DETAILED DESCRIPTION

[00129] Hereinafter, exemplary embodiments will be described in detail by referring to the accompanying drawings.

[00130] Fig. 1 shows that a carrier 1 according to the disclosure is connected to a vehicle seat 2, in which the carrier 1 is placed on a seating 2A of the vehicle seat 2, and a front edge IE of the carrier 1 abuts against a back 2B of the vehicle seat 2. It should be noted, although the carrier 1 shown in the drawings is a baby basket, the disclosure is not limited thereto, and the carrier 1 according to the disclosure can serve to carry people, animals or articles, including but not limited to a baby basket, a sleeping box, a safety seat, an animal carrying device or an article carrying device and the like.

[00131] For sake of facilitating description, a baby basket will be taken as an example of the carrier 1 in the present disclosure. As shown in Figs. 5 and. 10, the baby basket 1 includes a backrest 1A, a sitting part IB, two side parts IClocated on left and right sides of the backrest 1A and the sitting part IB, and a supporting seat ID located at a lower part of the basket 1. As shown in Fig. 2B, the baby basket 1 may further include a handle IF for lifting the basket 1. The position where the two side parts 1C of the basket 1 are connected to the handle IF is a lifting point G The lifting point G can be, for example, a rotating shaft connecting the two side parts 1C of the basket 1 with the handle IF.

[00132] In addition, the direction for a baby on the backrest 1A of the basket 1 to face is defined as front, the direction for the baby to face back is defined as back, the left and right direction of the baby in the basket 1 is defined as lateral, the side of the basket 1 for carrying the baby is defined as an inner side of the basket 1 , and the opposite side is defined as an outer side of the basket 1. Other forms of the carrier 1 may be similar or different in structure from a baby basket.

[00133] As shown in Figs. 2A and. 2B, in order to safely and reliably connect the carrier 1 to the vehicle seat 2, the carrier 1 can be provided with an anchor assembly. The anchor joint 20 includes an anchor joint 20, and an engagement interface 20 A of the anchor joint 20 can be directly engaged with corresponding accessory, such as a connecting rod, a connecting ring, an anchoring interface and the like (usually located at the position where the seating 2A and the back 2B of the vehicle seat 2are connected to each other) on the vehicle seat 2, such that no additional base is necessary, which makes connection of the carrier 1 on the vehicle seat 2 more convenient and the structure simpler. According to actual situation of the vehicle seat 2, the engagement interface 20A of the anchor joint 20 may be lower than a sitting surface of the seating 2A of the vehicle seat 2, or located at the position where the seating 2A and the back 2B of the vehicle seat 2 are connected to each other, but the disclosure is not limited thereto.

[00134] Movable Support of Anchor Assembly

[00135] As shown in Fig. 3, in order to enable the carrier 1 to be stably connected on different vehicles, the anchor assembly according to the disclosure further includes a movable support 10. The movable support 10 is installed on the carrier 1 and connected to or integrally formed with the anchor joint 20. Specifically, the movable support 10 and the anchor joint 20 can be two members made separately, and then connected together by welding, riveting, screwing and the like. The movable support 10 and the anchor joint 20 may also be a single member integrally formed.

[00136] The movable support 10 may be arranged such that a part or the whole thereof can move in respect with the carrier 1, so the distance of the anchor joint 20 connected to the movable support 10 in respect with the carrier 1 can be changed. The “movement” of a part or the whole of the movable support 10 in respect with the carrier 1 may include the case where two members translate in respect with each other, or the case where two threaded structures move axially when they are screwed in respect with each other, etc.

[00137] In an embodiment, the movable support 10 may be arranged such that a common length of the movable support 10 and the anchor joint 20 exposed from the carrier 1 may be more than half of a total length of the movable support 10 and the anchor joint 20.

[00138] In another embodiment, the total length of the movable support 10 and the anchor joint 20 is 350 mm, and the movable support 10 can be arranged such that the common length of the movable support 10 and the anchor joint 20 exposed from the carrier 1 is 269 mm when the movable support 10 is fully extended. [00139] In yet another embodiment, as shown in Fig. 2B, the front edge IE of the carrier 1 may be taken as a reference line SI, a vertical line passing through the engagement interface 20 A of the anchor joint 20 may be taken as a joint line S2, and a distance of the joint line S2 in respect with the reference line SI is T, when the joint line S2 is on the left of the reference line SI in the figure, the distance T is positive, and when the joint line S2 is on the right of the reference line SI in the figure, the distance T is negative. Accordingly, the movable support 10 can be arranged such that when the engagement interface 20A of the anchor joint 20 is engaged with the corresponding accessory on -k; the vehicle seat 2, the distance T of the joint line S2 in respect with the reference line SI in the front-rear direction of the carrier 1 is in the range of 100 mm to -30 mm. That is, the movable support 10 can be arranged such that when the engagement interface 20A of the anchor joint 20 is engaged with the corresponding accessory on the vehicle seat 2, in the case that the engagement interface 20A is in front of the front edge IE of the carrier 1, the distance T of the engagement interface 20A in respect with the front edge IE of the carrier 1 in the front-rear direction of the carrier 1 is less than or equal to 100 mm, and in the case that the engagement interface 20A is behind the front edge IE of the carrier 1, the distance T of the engagement interface 20A in respect with the front edge IE of the carrier 1 in the front-rear direction of the carrier 1 is less than or equal to 30 mm. Accordingly, it can be ensured that when the carrier 1 is connected to the vehicle seat 2, the anchor joint 20 is sufficiently engaged with the corresponding accessory on the vehicle seat 2, and the front edge IE of the carrier 1 can tightly abut against the back 2B of the vehicle seat 2.

[00140] In another embodiment, as shown in Fig. 30, two sides of the front edge IE of the carrier 1 may be provided with heightening parts 1E1, and the heightening parts 1E1 are arranged to increase height of the two sides of the front edge IE, thereby preventing the carrier 1 from tipping.

[00141] It should be understood, the disclosure is not limited to the above embodiments.

[00142] The moving direction M of the movable support 10 is inclined to the horizontal plane

H.

[00143] In an embodiment, as shown in Fig. 2B, the moving direction M of the movable support 10 has an included angle a in respect with the horizontal plane H, and the included angle acan be arranged to be greater than 0° and less than or equal to 30°. In an embodiment, the included angle a of the moving direction M of the movable support 10 in respect with the horizontal plane H may be 13°. Moreover, the included angle a of the moving direction M of the movable support 10 in respect with the horizontal plane H is as same as an included angle of each long slot 103 in respect with the horizontal plane H. The numerical range of the above included angle can make the anchor assembly of the carrier 1 suitable for most vehicle seats 2.

[00144] Of course, the disclosure is not limited thereto, and the included angle a of the moving direction M of the movable support 10 in respect with the horizontal plane H can be arranged to other suitable angles greater than 30° according to actual requirements.

[00145] However, in order to more firmly and stably connect the carrier 1 to the vehicle seat 2, while avoid the situation that the carrier 1 is tipped due to an excessively large included angle a, as shown in Fig. 2B, the included angle ashould be less than or equal to an included angle P of a connecting line N between the lifting point G of the carrier 1 and the engagement interface 20A of the anchor joint 20 in respect with the horizontal plane H. Alternatively, an included angle 0 of the connecting line N between the lifting point G of the carrier 1 and the engagement interface 20A of the anchor joint 20 in respect with the moving direction M of the movable support 10 should be between 10° and 45°. Or alternatively, if the carrier 1 is a baby basket, in this embodiment, the acute included angle of an extending direction of the backrest 1A of the baby basket in respect with the moving direction M of the movable support 10 may be 32°. Such arrangement not only makes the carrier 1 be connected to the vehicle seat 2 more firmly and stably, but also facilitates the user to lift the carrier 1 after the anchor joint 20 is unlocked.

[00146] It should be noted, the included angle a of the moving direction M of the movable support 10 in respect with the horizontal plane H, the included angle P of the connecting line N between the lifting point G of the carrier 1 and the engagement interface 20A of the anchor joint 20 in respect with the horizontal plane H, and the included angle of the extending direction of the long slot 103 in respect with the horizontal plane H, all the included angles mentioned here are in respect with the horizontal plane H (see Fig. 2B). if the carrier 1 is inclined or overturned in respect with the horizontal plane H, the moving direction M of the movable support 10, the connecting line N, and the extending direction of the long slot 103 will all be inclined or overturned following the carrier 1, thus causing inestimable changes in the included angles of the moving direction M of the movable support 10, the connecting line N, and the extending direction of the long slot 103 in respect with the horizontal plane H, which obviously deviates from the design purpose of the disclosure. Therefore, in the disclosure, the setting ranges of the above included angles are discussed on the premise that the carrier 1 is placed on a horizontal plane and remains fixed in respect with the horizontal plane. All the above included angles belong to an inherent property of the carrier 1 itself and will not change due to changing in the installation environment of the carrier 1. Specifically, in reality, the sitting surface of the seating 2A of the vehicle seat 2 is sometimes not a horizontal plane, or the seating 2A of the vehicle seat 2 is elastic, which may cause the carrier 1 on the seating 2A not be surely on the horizontal plane H, but these factors will not change the above-mentioned included angles of the carrier 1 according to the disclosure. Furthermore, the included angle a of the moving direction M of the movable support 10 of the carrier 1 according to the disclosure in respect with the horizontal plane H, the included angle P of the connecting line N between the lifting point G of the carrier land the engagement interface 20A of the anchor joint 20 in respect with the horizontal plane H, the included angle of the extending direction of the long slot 103 in respect with the horizontal plane H, these included angles will not be changed due to factors such as the carrier 1 being placed on a non-horizontal plane or an elastic sitting surface or the carrier 1 being turned over in respect with the horizontal plane.

[00147] On the other hand, the movable support 10 can also be arranged such that the included angle a of the moving direction of the movable support 10 in respect with the horizontal plane is variable. For example, in an embodiment, in the case that the movable support 10 is arranged to include a movable part and an installation part, and the movable part can move in respect with the carrier 1, the installation part of the movable support 10 can be rotatably installed on the carrier 1 (not shown), such that the included angle a of the moving direction of the movable support 10 in respect with the horizontal plane can be changed as required, so the anchor joint 20 can be better engaged with corresponding accessories on different vehicle seats 2. Of course, as mentioned above, the included angle a of the moving direction of the movable support 10 in respect with the horizontal plane should not exceed the included angle P of the connecting line N between the lifting point G of the carrier 1 and the engagement interface 20A of the anchor joint 20 in respect with the horizontal plane H, so as to prevent the carrier 1 from tipping. Similarly, it should be noted, the change of the included angle a of the moving direction M of the movable support 10 in respect with the horizontal plane H discussed here is only caused by the rotation of the movable support 10, rather than caused by the carrier 1 being placed on a non-horizontal plane or an elastic sitting surface or the carrier 1 being turned over in respect with the horizontal plane.

[00148] When the user connects the carrier 1 to the vehicle seat 2 as shown in Fig. 1, he firstly moves the movable support 10 such that the anchor joint 20 is farthest away from the carrier 1, then moves the anchor joint 20 toward and finally is engaged with the corresponding accessory on the vehicle seat 2, next, he pushes the carrier 1 toward the back 2B of the vehicle seat 2 until the front edge IE of the carrier 1 abuts against the back 2B of the vehicle seat 2, thereby ensuring the carrier 1 to be stably seated on the vehicle seat 2. Finally, the user positions the movable support 10 in this position such that it cannot move any more. Accordingly, the carrier 1 is safely and reliably connected to the vehicle seat 2.

[00149] As shown in Figs. 5 and. 10, in an embodiment where the movable support 10 is arranged to be movable as a whole in respect with the carrier 1 , the carrier 1 may be provided with a support guiding part 102 for guiding the movement of the movable support 10. The support guiding part 102 can adopt various structures such as chute, guide rail, guide pin and the like to guide the movement of the entire movable support 10. Moreover, the support guiding part 102 may be formed inside, between and/or outside the component parts of the carrier 1.

[00150] In the embodiments shown in Figs. 4, 5, 6 and 10, the support guiding part 102 may be formed as a housing extending on an outer surface of the supporting seat ID of the carrier lin the front-rear direction, passing through the sitting part IB and protruding upward between the sitting part IB and the side parts 1C. That is, the support guiding part 102 can be arranged such that the maximum distance LI between two anchor joints 20 (i.e., the distance between lateral outer surfaces of the two anchor joints 20) on the movable support 10 moving along the support guiding part 102 is less than or equal to the distance L2 between the outer surface of the two side parts 1C of the carrier 1 (see Fig. 6), thereby realizing the function of stably moving the movable support 10 without increasing the overall volume of the carrier 1, and making the overall structure of the carrier 1 compact, especially without occupying additional space in the width direction (i.e., the left-right lateral direction). However, the disclosure is not limited thereto.

[00151] In this embodiment, a part of the support guiding part 102 located on the outer surface of the supporting seat ID of the carrier 1 is a guide rail, and a part of the housing located in the sitting part IB and formed between the sitting part IB and the side parts 1C is formed with a chute for the movable support 10 to slide therein. An inner contour of the chute may be formed to match an outer contour of the movable support 10. Although as shown in Figs. 5 and 10, a cross section of the inner contour of the chute and a cross section of the outer contour of the movable support 10 are approximately square, the disclosure is not limited thereto.

[00152] In another embodiment, the support guiding part 102 may be formed outside the component parts of the carrier 1. For example, the support guiding part 102 may be a guide rail or a guide pin arranged on the outer surface of each of the side parts 1C of the carrier 1, and is arranged such that the movable support 10 can be entirely movably installed on the carrier 1 by cooperating with the support guiding part 102.

[00153] In an embodiment where a part of the movable support 10 is arranged to be movable in respect with the carrier 1, the movable support 10 can be two members (a movable part and an installation part) which can move in respect with each other, such as a telescopic structure (not shown), i.e., a part of the movable support 10 (the movable part) can move in respect with the other part (the installation part). Among them, the installation part is installed on the carrier 1, and the movable part is connected to the anchor joint 20. By moving the movable part in respect with the installation part and the carrier 1, the distance of the anchor joint 20 in respect with the carrier 1 can be changed.

[00154] In the carrier 1 according to the disclosure, since the distance of the anchor joint 20 in respect with the carrier 1 can be changed, even if it is used on a different vehicle seat 2, the anchor joint 20 on the carrier 1 can extend a proper distance in respect with the carrier 1, thereby being suitable for engaging with the corresponding accessory on the different vehicle seat 2.

[00155] It should be understood, although the anchor joint 20 is shown to be connected to an end of the movable support 10, the anchor joint 20 may be connected to other suitable parts of the movable support 10 as long as it can change its distance in respect with the carrier 1 following the movement of the movable support 10.

[00156] In addition, connection between the anchor joint 20 and the movable support 10 may be a fixed connection or a movable connection. For example, the movable connection between the anchor joint 20 and the movable support 10 may be a rotary connection, or an elastic connection by means of elastic members such as rubber, spring and the like, such that the angle of the anchor joint 20 in respect with the movable support 10 can be changed, so as to facilitate the anchor joint 20 to be better engaged with the corresponding accessory on the different vehicle seat 2.

[00157] In the drawing, there are two anchor assemblies respectively arranged on two sides of the carrier 1. As shown in Fig. 3, a crossbar 11 is connected between the movable supports 10 of the two anchor assemblies. The crossbar 11 increases strength of the anchor assemblies, and In the meanwhile realizes a synchronous movement of the two movable supports 10. In an embodiment, the crossbar 11 is arranged below the movable supports 10, so as to be exposed from the lower part of the carrier 1, thereby enabling the user to contact and operate an unlocking operation member 40 arranged thereon (will be described later).

[00158] In order to enable the crossbar 11 to move together with the movable supports 10, the carrier 1 is provided with a long slot 103 for the crossbar 11 to move therein. In the embodiments shown in Figs. 4, 11, 27 and 29, the long slot 103 is formed in the supporting seat ID of the carrier 1, and its extending direction is parallel to the moving direction M of the movable supports 10. In an embodiment, the included angle of the extending direction of the long slot 103 in respect with the horizontal plane H can also be arranged to be greater than 0° and less than or equal to 30°.

[00159] Of course, the disclosure is not limited thereto, and the number of the anchor assemblies can also be one, or more than two, which can be flexibly arranged according to actual requirements.

[00160] Adjustment Device of Carrier

[00161] The carrier 1 further includes an adjustment device 100. The adjustment device 100 is arranged to be able to adjust the moving distance of the movable supports 10 in respect with the carrier 1. Specifically, when the user connects the carrier 1 to the vehicle seat 2, the movable supports 10 can be adjusted by the adjustment device 100 to move in respect with the carrier 1 until the anchor joint 20 connected to or integrally formed with the movable supports 10 is engaged with the corresponding accessory on the vehicle seat 2. Moreover, the adjustment device 100 can also position the movable supports 10 at this distance to ensure that the carrier 1 is safely and reliably connected to the vehicle seat 2.

[00162] However, the disclosure is not limited thereto, and the carrier 1 may not include the adjustment device 100. For example, in an embodiment, in the case that the movable supports 10 is arranged to include a movable part and an installation part, and the movable part can move in respect with the carrier 1, the movable part and the installation part may be connected by screwing, and the movable part can move in respect with the installation part along an axial direction of the movable part (not shown) by being screwed. When the user is ready to connect the carrier 1 to the vehicle seat 2, he can screw the movable part of the movable supports 10 to move in respect with the installation part along the axial direction of the movable part until the anchor joint 20 connected to or integrally formed with the movable part is engaged with the corresponding accessory on the vehicle seat 2. At this time, the movable supports 10 can be positioned at this distance without adjusting the movable supports 10 by the adjustment device 100.

[00163] Hereinafter, an embodiment in which the carrier 1 according to the disclosure uses the adjustment device 100 will be described in detail by referring to the drawings.

[00164] As shown in Figs. 7 and 9, the adjustment device 100 may include at least two distance positioning members 110 arranged on the movable supports 10 and a movable positioning member 120 arranged on the carrier 1. Among them, the movable positioning member 120 can move between an engaged position and a disengaged position. As shown in Fig. 7, the movable positioning member 120 is engaged with one of the distance positioning members 110 when is at the engaged position, thereby positioning the movable supports 10 at this position to position the distance of the movable supports 10 in respect with the carrier 1; moreover, as shown in Fig. 9, the movable positioning member 120 is disengaged from the distance positioning member 110 at the disengaged position, such that the movable supports 10 is released from positioning and can move in respect with the carrier 1.

[00165] It should be understood, arranged positions of the distance positioning members 110 and the movable positioning member 120 can be interchanged, that is, the distance positioning members 110 can be arranged on the carrier 1, and the movable positioning member 120 can be arranged on the movable supports 10. In addition, the movement of the movable positioning member 120 between the engaged position and the disengaged position may be pivoting, sliding, or a combination of pivoting and sliding.

[00166] In an embodiment, the movable positioning member 120 is a positioning hook pivotably arranged on the carrier 1 , and the distance positioning members 110 are at least two positioning holes arranged on the movable supports 10. Of course, the disclosure is not limited thereto, and the movable positioning member 120 and the distance positioning members 110 may be, for example, two members cooperating in concave and convex, or pin rolls, slotted holes and the like.

[00167] For convenience of description, the positioning holes 110 and the positioning hook 120 will be taken as example for explanation.

[00168] The positioning hook 120 can be pivoted between an engaged position and a disengaged position. As shown in Fig. 7, the positioning hook 120 will be engaged with one of the positioning holes 110 when pivoted to the engaged position. As shown in Fig. 9, the positioning hook 120 is disengaged from the positioning holes 110 when pivoted to the disengaged position.

[00169] The at least two positioning holes 110 can be arranged at equal or unequal intervals along the moving direction of the movable supports 10, such that when the positioning hook 120 is engaged with different positioning holes 110, the movable supports 10 can be positioned at different distances in respect with the carrier 1, so as to satisfy the requirement of connecting the carrier 1 to a different vehicle seat 2.

[00170] In order to facilitate the user’s operation, the adjustment device 100 may further include an adjusting operation member 130. The adjusting operation member 130 is movably disposed on the carrier 1, and is arranged to be able to drive the positioning hook 120 to move toward the disengaged position. The adjusting operation member 130 may take various structural forms such as a handle, a wrench, a lever, a button, a knob and the like. Moreover, the movement of the adjusting operation member 130 on the carrier 1 may be performed in various forms, such as sliding, pivoting or screwing and the like, as long as it can drive the positioning hook 120 to move.

[00171] Of course, the adjustment device 100 may not include the adjusting operation member 130, and the positioning hook 120 may be arranged such that the user can contact and operate the carrier 1 from outside.

[00172] After the adjusting operation member 130 drives the positioning hook 120 to move to the disengaged position under operation of the user, the adjusting operation member 130 can return to an initial position by means of a reset elastic member (not shown). It should be understood, the reset elastic member is not necessary, and the adjusting operation member 130 may be arranged to return to the initial position under operation of the user.

[00173] In the embodiments shown in Figs. 7 and 9, the adjustment device 100 may further include a linked movement member 140. A first end 141 of the linked movement member 140 is connected to the adjusting operation member 130, and a second end 142 of the linked movement member 140 is directly or indirectly connected to the positioning hook 120, such that the adjusting operation member 130 drives the positioning hook 120 via the linked movement member 140.

[00174] The linked movement member 140 can be a flexible member made of various materials, such as a silk, a thread, a rope and the like, which can withstand tensile force, or a rigid member in the form of a rod, a plate or a block.

[00175] Of course, the adjustment device 100 may not include the linked movement member 140, and the adjusting operation member 130 may directly connect to and drive a movable positioning member such as the positioning hook 120, but in such case, the arranged position of the adjusting operation member 130 on the carrier is not as flexible as that in the case of including the linked movement member 140.

[00176] In the embodiments shown in Figs. 7 and 9, the positioning hook 120 may be provided with a driving part 121. The driving part 121 is directly or indirectly connected to the second end 142 of the linked movement member 140. Of course, the disclosure is not limited thereto. More specifically, the positioning hook 120 may not be provided with the driving part 121, and in such case, the second end 142 of the linked movement member 140 may be directly or indirectly connected to a body of the positioning hook 120, as long as the linked movement member 140 can drive the positioning hook 120 to move.

[00177] In an embodiment, the adjusting operation member 130 is a turnable knob, and the linked movement member 140 is a pull rope wound around the knob 130. By turning the knob 130, the user can wind more pull rope 140 around the knob 130, thus pulling the pull rope 140 to drive the positioning hook 120 connected to the second end 142 of the pull rope 140.

[00178] Hereinafter, the description will be carried out by taking the adjusting operation member 130 being a handle slidably arranged on the carrier 1 and being slidable under pulling of the user as example with reference to the drawings, especially Fig. 12.

[00179] In an embodiment, the adjusting operation member 130 is disposed on the outer surface of the carrier 1 (see Fig. 11), and the linked movement member 140 extends between the two side parts 1C of the carrier 1 (see Fig. 10). In this embodiment, one of the first end 141 of the linked movement member 140 and the adjusting operation member 130 needs to firstly pass through the carrier 1 to be connected to the other.

[00180] As shown in Figs. 6, 8, 10, the carrier 1 is penetratingly provided with a strip-shaped connecting slot 101 at the position where the adjusting operation member 130 is arranged, and a bulged post 131 on the adjusting operation member 130 passes through the connecting slot 101, thus enabling the first end 141 of the linked movement member 140 to be connected to the bulged post 131. Moreover, when the adjusting operation member 130 is moving, the bulged post 131 on the adjusting operation member 130 can slide in the connecting slot 101.

[00181] In yet another embodiment, the bulged post 131 may has a screw 132 connected thereon (see Fig. 12), and a diameter of a cap of the screw 132 is larger than a width of the connecting slot 101. When the adjusting operation member 130 is installed on the carrier 1, the bulged post 131 passes through the connecting slot 101, and then the screw 132 is connected onto the bulged post 131. The screw 132 can prevent the bulged post 131 of the adjusting operation member 130 from separating from the connecting slot 101, thus preventing the adjusting operation member 130 from separating from the carrier 1.

[00182] Locking and Unlocking of Anchor Joint

[00183] In order to facilitate the user to operate the anchor joint 20 of the anchor assembly and switch it between the locked state and the unlocked state, as shown in Figs. 12 to 21, the anchor assembly further includes an unlocking drive member 30 and an unlocking operation member 40.

[00184] Among them, the unlocking drive member 30 is arranged on the movable support 10 and can slide along the movable support 10 between a driving position (see Figs. 13 and 19) and a non-driving position (see Figs. 14 and 21). After the anchor joint 20 enters the locked state, the unlocking drive member 30 will slide to the driving position. In addition, the unlocking drive member 30 can allow the anchor joint 20 to enter the unlocked state when sliding to the non-driving position.

[00185] The unlocking operation member 40 is operatively connected to the unlocking drive member 30, and is arranged to be able to drive the unlocking drive member 30 to slide to the non-driving position.

[00186] In an embodiment, as shown in Fig. 13, the unlocking operation member 40 is connected to and drives the unlocking drive member 30 via a transmission member 50. However, the disclosure is not limited thereto, the transmission member 50 can be omitted, and the unlocking operation member 40 may be directly connected to and drive the unlocking drive member 30.

[00187] As shown in Figs. 13 and 14, a middle part 51 of the transmission member 50 is pivotably connected to the movable supports 10, a first end 52 of the transmission member 50 is connected to the unlocking operation member 40, and a second end 53 of the transmission member 50 is directly or indirectly connected to the unlocking drive member 30.

[00188] The first end 52 and the second end 53 of the transmission member 50 can rotate around a rotary connection of the middle part 51. Accordingly, when the user operates the unlocking operation member 40, the movement of the unlocking operation member 40 will be transmitted to the unlocking drive member 30 via the transmission member 50.

[00189] Specifically, as shown in Fig. 14, when the user exerts an acting force on the unlocking operation member 40 in a second rotation direction R2, the first end 52 of the transmission member 50 connected to the unlocking operation member 40 will be pivoted in the second rotation direction R2 following the unlocking operation member 40, and the second end 53 of the transmission member 50 connected to the unlocking drive member 30 will also be pivoted in the second rotation direction R2, whereby the second end 53 drives the unlocking drive member 30 to slide to the non-driving position along the movable support 10, thereby allowing the anchor joint 20 to enter the unlocked state.

[00190] On the other hand, when the anchor joint 20 enters the locked state, the unlocking drive member 30 will slide to the driving position along the movable support 10 under driving of a sliding member 22 (will be described later) connected to it, without the user exerting an acting force on the unlocking operation member 40. As shown in Fig. 13, the second end 53 of the transmission member 50 is pivoted toward the first rotation direction Rl under driving of the unlocking drive member 30, and the first end 52 of the transmission member 50 is also pivoted toward the first rotation direction Rl, whereby the first end 52 drives the unlocking operation member 40 to be pivoted toward the first rotation direction Rl .

[00191] Although the transmission member 50 in Figs. 13 and 14 has a cylindrical shape, the disclosure is not limited thereto, and the transmission member 50 may take various structures such as a sheet shape or a rod shape.

[00192] Figs. 13 and 14 also show an embodiment where the second end 53 of the transmission member 50 is indirectly connected to the unlocking drive member 30. Among them, a latch 54 passes through the second end 53 of the transmission member 50, a slotted hole 12 of the movable supports 10, and a connecting hole 31 of the unlocking drive member 30, such that the second end 53 of the transmission member 50 is connected to and drives the unlocking drive member 30 via the latch 54. In order to facilitate the second end 53 of the transmission member 50 to be pivoted toward the first rotation direction R1 or the second rotation direction R2, the slotted hole 12 of the movable supports 10 is arranged as an arc-shaped strip slot, such that the latch 54 can slide in the slotted hole 12.

[00193] In another embodiment, the latch 54 may be integrally formed with the second end 53 of the transmission member 50. Accordingly, the second end 53 of the transmission member 50 is directly connected to and drives the unlocking drive member 30.

[00194] It should be understood, in the carrier 1 according to the disclosure, the adjusting operation member 130 and the unlocking operation member 40 can be functionally interchanged. That is, the adjusting operation member 130 can be arranged to drive the unlocking drive member 30 to slide toward the non-driving position, and the unlocking operation member 40 can be arranged to drive the positioning hook 120 to move toward the disengaged position, for this, only relevant members need to be slightly modified based on the above embodiment.

[00195] As shown in Figs. 15 to 21, the anchor joint 20 of the anchor assembly includes a joint support 21, a sliding member 22, and a locking hook 23.

[00196] Among them, the joint support 21 is connected to the movable support 10. The sliding member 22 is slidably arranged in the joint support 21 and connected to the unlocking drive member 30, such that the sliding member 22 slides together with the unlocking drive member 30 between the driving position and the non-driving position. In an embodiment, the joint support 21 is provided with a fixed pin 21 A, and the sliding member 22 is correspondingly provided with a strip-shaped fixed pin slide slot 22C for the fixed pin 21 A to slide therein, thereby guiding the sliding member 22 to slide in the joint support 21 and preventing the sliding member 22 from separating from the joint support 21.

[00197] The locking hook 23 is arranged in the joint support 21 to be rotatable between a locked position and an unlocked position, so as to lock or unlock a corresponding accessory on the vehicle seat 2. Specifically, during a locking process, as shown in Fig. 19, when the anchor joint 20 is engaged with the corresponding accessory such as a connecting rod, a connecting ring, an anchoring interface and the like (not shown) on the vehicle seat 2, the corresponding accessory enters the engagement interface 20A of the anchor joint 20, and during this process, the corresponding accessory will drive the locking hook 23 to rotate to the locked position, such that the locking hook 23 locks the corresponding accessory. In addition, when the locking hook 23 rotates to the locked position, the sliding member 22 slides to the driving position under driving of a sliding member reset elastic member 25 (will be described later), and brings the unlocking drive member 30 to slide to the driving position. In an unlocking process, as shown in Fig. 21, when the sliding member 22 slides to the non-driving position, the locking hook 23 is allowed to rotate towards the unlocked position, such that the locking hook 23 unlocks the corresponding accessory.

[00198] In order to rotate the locking hook 23 toward the unlocked position, as shown in Figs. 15 and 17A-17B, the anchor joint 20 may include a locking hook reset elastic member 24. The locking hook reset elastic member 24 is arranged to drive the locking hook 23 to rotate toward the unlocked position.

[00199] In an embodiment, the locking hook reset elastic member 24 is a torsion spring arranged around the rotating shaft 23B of the locking hook 23 (see Figs. 17A and 17B). A first end 24A of the torsion spring may be connected to the locking hook 23, and a second end 24B of the torsion spring may be connected to the joint support 21. Of course, the disclosure is not limited thereto, and the locking hook reset elastic member 24 may take other forms of elastic members as long as it can drive the locking hook 23 to rotate toward the unlocked position.

[00200] When the anchor joint 20 is in the locked state, that is, the locking hook 23 is in the locked position, in order to prevent the risk that the carrier 1 is separated from the vehicle seat 2 due to accidental unlocking between the anchor joint 20 and the corresponding accessory of the vehicle seat 2, as shown in Figs. 17A, 17B, 19 and 21, the anchor joint 20 may include a sliding pin 22A connected to the sliding member 22, and the locking hook 23 may be correspondingly provided with a recess 23A engaged with the sliding pin 22A. The recess 23A on the locking hook 23 is arranged such that when the locking hook 23 rotates to the locked position, as shown in Fig. 19, the sliding pin 22A of the sliding member 22 is engaged with the recess 23 A of the locking hook 23, so as to prevent the locking hook 23 from rotating toward the unlocked position, thereby keeping the locking hook 23 in the locked position. When the anchor joint 20 needs to be unlocked, as shown in Fig. 21, the sliding member 22 slides to the non-driving position, and the sliding pin 22A of the sliding member 22 is disengaged from the recess 23A of the locking hook 23, so the locking hook 23 rotates to the unlocked position under acting of the locking hook reset elastic member 24.

[00201] In order to facilitate the sliding pin 22A to slide following the sliding member 22 in the joint support 21, the joint support 21 is correspondingly provided with a strip-shaped sliding pin sliding slot 21B for the sliding pin 22A to slide therein, thereby guiding the sliding member 22 to slide in the joint support 21 and preventing the sliding member 22 from separating from the joint support 21.

[00202] In an embodiment, the anchor joint 20 may further include a sliding member reset elastic member 25. The sliding member reset elastic member 25 is arranged to drive the sliding member 22 to slide toward the driving position. As shown in Figs. 19 and 21, the sliding member reset elastic member 25 may be arranged between the fixed pin 21 A of the joint support 21 and an inner wall of the sliding member 22. As shown in Fig. 19, when the sliding member 22 and the unlocking drive member 30 are in the driving position, the distance between the fixed pin 21 A of the joint support 21 and the inner wall of the sliding member 22 is the largest, and the sliding member reset elastic member 25 is in a relative small stressed state, so the sliding member reset elastic member 25 exerts a relative small acting force on the sliding member 22, and such acting force helps to keep the sliding member 22 in the driving position, such that the sliding pin 22A of the sliding member 22 remains engaged with the recess 23 A of the locking hook 23. As shown in Fig. 21, when the sliding member 22 slides to the non-driving position, the distance between the fixed pin 21 A of the joint support 21 and the inner wall of the sliding member 22 is the smallest, and the sliding member reset elastic member 25 is in a relative large stressed state, so the sliding member reset elastic member 25 will exert a relative large acting force on the sliding member 22, and such acting force will drive the sliding member 22 to slide toward the driving position.

[00203] Hereinafter, the overall working process of the anchor joint 20, the unlocking drive member 30, and the unlocking operation member 40 will be described.

[00204] In a locking process, the user engages the anchor joint 20 to the corresponding accessory such as a connecting rod, a connecting ring, an anchoring interface and the like on the vehicle seat 2, and the corresponding accessory enters the engagement interface 20A of the anchor joint 20. In this process, the corresponding accessory will drive the locking hook 23 to rotate to the locked position, so the locking hook 23 locks the corresponding accessory. When the locking hook 23 rotates to the locked position, the sliding member 22 slides to the driving position under driving of the sliding member reset elastic member 25. Moreover, as shown in Fig. 19, the unlocking drive member 30 connected to the sliding member 22 also slides to the driving position. Accordingly, when the sliding member 22 slides to the driving position, as shown in Fig. 19, the sliding pin 22A of the sliding member 22 enters a position where it is engaged with the recess 23 A of the locking hook 23, so as obstruct the locking hook 23 from rotating toward the unlocked position, thereby keeping the locking hook 23 in the locked position. When the unlocking drive member 30 slides to the driving position, as shown in Fig. 13, the second end 53 of the transmission member 50 is pivoted toward the first rotation direction Rl under driving of the unlocking drive member 30, and the first end 52 of the transmission member 50 is also pivoted toward the first rotation direction Rl, whereby the first end 52 drives the unlocking operation member 40 to be pivoted toward the first rotation direction Rl .

[00205] In an unlocking process, as shown in Fig. 14, the user exerts an acting force on the unlocking operation member 40 toward the second rotation direction R2, the first end 52 of the transmission member 50 connected to the unlocking operation member 40 is pivoted toward the second rotation direction R2 following the unlocking operation member 40, and the second end 53 of the transmission member 50 connected to the unlocking drive member 30 is also pivoted toward the second rotation direction R2, such that the second end 53 drives the unlocking drive member 30 to slide along the movable support 10 to the non-driving position. Then, the sliding member 22 connected to the unlocking drive member 30 also slides to the non-driving position. Accordingly, when the sliding member 22 also slides to the non-driving position, as shown in Fig. 21, the sliding pin 22A of the sliding member 22 is disengaged from the recess 23 A of the locking hook 23, then the locking hook 23 rotates to the unlocked position under acting of the locking hook reset elastic member 24, thereby making the locking hook 23 unlock the corresponding accessory.

[00206] In order to make the anchor joint 20 more aesthetically pleasing, the anchor joint 20 further includes a joint housing 26. The joint housing 26 accommodates the joint support 21, the sliding member 33, and the locking hook 23 therein.

[00207] After the anchor joint 20 is provided with the joint housing 26, it will be difficult for the user to confirm whether the anchor joint 20 is in the locked state or the unlocked state. For this, in an embodiment, the anchor joint 20 according to the disclosure is further provided with an indication device. As shown in Fig. 15, the joint housing 26 has an indication window 26A formed as passing through the joint housing 26. Meanwhile, as shown in Figs. 15, 16 and 17A, the sliding member 22 is provided with an indication member 22B. The indication member 22B includes a first region 22B1 and a second region 22B2 adjacent to each other. The first region 22B1 and the second region 22B2 may have colors or patterns different from each other, so as to indicate that the anchor joint 20 is in the locked state or the unlocked state, respectively. The indication member 22B can slide following the sliding member 22, such that the first region 22B1 and the second region 22B2 are exposed switchably from the indication window 26A, thereby indicating the state of the anchor joint 20 to the user.

[00208] Specifically, the first region 22B1 may be arranged in green or printed with the word “locked” to indicate that the anchor joint 20 is in the locked state, and the second region 22B2 may be arranged in red or printed with the word “unlocked” to indicate that the anchor joint 20 is in the unlocked state. When the sliding member 22 slides to the driving position following the unlocking drive member 30, the green or the word “locked” of the first region 22B1 will be exposed from the indication window 26A, thereby indicating to the user that the anchor joint 20 is in the locked state. When the sliding member 22 slides to the non-driving position following the unlocking drive member 30, the red or the word “unlocked” of the second region 22B2 will be exposed from the indication window 26A, thereby indicating to the user that the anchor joint 20 is in the unlocked state.

[00209] Connecting Post

[00210] The carrier 1 according to the disclosure can be connected not only to the vehicle seat 2, but also to an application device (see Figs. 92 to 100). Here the application device can also be called as carrier application device, which refers to a device the carrier 1 can be placed or applied thereto, including but not limited to a baby stroller, a baby chair for carrying baby, a child stroller for carrying child, or a cart for articles or animals.

[00211] As shown in Figs. 2A and. 2B, in order to facilitate connecting the carrier 1 to the carrier application device, the carrier 1 may be provided with a connecting post 200. The connecting post 200 on the carrier may be arranged being able to move between an extended position and a retracted position, so as to be engaged with a corresponding accessory on the carrier application device, thereby enabling a user to easily connect or remove the carrier 1 to/from the carrier application device.

[00212] In an embodiment, the connecting post 200 may be arranged being able to be driven by the adjusting operation member 130. That is, when the user operates the adjusting operation member 130, he can adjust the movable support 10, or alternatively, he can drive the connecting post 200. This can not only make the user’s operation more convenient, but also reduce the number of parts on the carrier 1 and simplify the structure. Of course, the disclosure is not limited thereto. In another embodiment, the connecting post 200 can also be operated by the user independently of the adjusting operation member 130.

[00213] Here, the connecting post 200 which can be driven by the adjusting operation member 130 to move toward the retracted position will be taken as an example for description. Meanwhile, as shown in Figs. 23B and 25B, the carrier 1 is provided with a connecting post reset elastic member 202. The connecting post reset elastic member 202 is arranged to drive the connecting post 200 to move toward the extended position.

[00214] In an embodiment, as shown in Figs. 7 and 9, the adjustment device 100 of the carrier 1 further includes a bringing member 150. The bringing member 150 is connected between the second end 142 of the linked movement member 140 and the driving part 121 of the positioning hook 120, and is movably arranged on the carrier 1. In this embodiment, the driving part 121 is in a state of being indirectly connected to the second end 142 of the linked movement member 140. The movement of the bringing member 150 on the carrier 1 can take various forms, such as sliding, rotating or a combination of sliding and rotating, as long as it can transmit the acting force of the linked movement member 140 to the positioning hook 120.

[00215] Specifically, in the embodiments shown in Figs. 7, 8, and 23B-25B, the bringing member 150 includes a bringing member front part 151 and a bringing member rear part 152 connected to each other by a T-shaped concave-convex fitting (see Figs. 23B and 25B). Among them, the bringing member front part 151 is connected to the second end 142 of the linked movement member 140, and the bringing member rear part 152 is provided with a strip-shaped bringing slot 152A for the driving part 121 of the positioning hook 120 to be inserted therein. The bringing slot 152A is arranged to be able to exert an acting force on the driving part 121 to make the positioning hook 120 pivot between the engaged position and the disengaged position. Of course, the disclosure is not limited thereto, and more specifically, the bringing member front part 151 and the bringing member rear part 152 of the bringing member 150 may be connected by various ways such as screwing, riveting and the like, or the bringing member 150 may be a single member. In addition, the bringing member 150 can take other structural forms to drive the positioning hook 120.

[00216] In order to realize that the connecting post 200 can be driven by the adjusting operation member 130, the bringing member 150 and the connecting post 200 may be arranged to be able to drive each other to move.

[00217] In the embodiment shown in Figs. 23B and 25B, the bringing member front part 151 is provided with a driving ramp 151 A, and the connecting post 200 is provided with a driving bulged part 201. The driving ramp 151 A and the driving bulged part 201 abut against each other, such that one of the bringing member front part 151 and the connecting post 200 can drive the other to move.

[00218] When the user acts on the adjusting operation member 130, the adjusting operation member 130 drives the bringing member 150 to move toward right in the figures via the linked movement member 140, and the bringing slot 152A of the bringing member rear part 152 drives the driving part 121 of the positioning hook 120 such that the positioning hook 120 moves toward the disengaged position and is disengaged from one of the positioning holes 110, so the movable support 10 can move in respect with the carrier 1. In the meanwhile, as shown in Fig. 23B, the driving ramp 151 A on the bringing member front part 151 pushes the driving bulged part 201 on the connecting post 200, such that the connecting post 200 moves toward the retracted position (the lower part in Fig. 23B) to retract back to the carrier 1, whereby the carrier 1 can be moved away from the carrier application device.

[00219] When the user no longer acts on the adjusting operation member 130, the adjusting operation member 130 will return to the initial position, so it will no longer drive the bringing member 150 to move toward right in the figure, so, as shown in Fig. 25B, the connecting post 200 moves toward the extended position (the upper part in Fig. 25B) to extend out of the carrier 1 under action of the connecting post reset elastic member 202, thereby enabling the carrier 1 to be connected to the carrier application device. In the meanwhile, the driving bulged part 201 on the connecting post 200 pushes the driving ramp 151 A on the bringing member front part 151, such that the bringing member 150 to move toward left in the figure, and the bringing slot 152A of the bringing member rear part 152 drives the driving part 121 of the positioning hook 120 such that the positioning hook 120 toward the engaged position and is engaged with one of the positioning holes 110, so the movable support 10 can be positioned in respect with the carrier 1.

[00220] Of course, the disclosure is not limited thereto, and the driving ramp 151 A may be arranged on the connecting post 200, while the driving bulged part 201 may be arranged on the bringing member front part 151. Alternatively, both the bringing member front part 151 and the connecting post 200 are provided with driving ramps 151 A abutting against each other.

[00221] Connecting Hook

[00222] As shown in Figs. 2A and. 2B, in order to facilitate to connect the carrier 1 to the carrier application device, the carrier 1 may also be provided with a connecting hook 300. The connecting hook 300 on the carrier is arranged to be movable between a connected position and a non-connected position, so as to be engages with a corresponding accessory on the carrier application device, thereby enabling the user to easily connect or remove the carrier 1 to/from the carrier application device.

[00223] In an embodiment, as shown in Figs. 27 and. 29, the connecting hook 300 may be arranged to be connected to the adjusting operation member 130, such that the adjusting operation member 130 can drive the connecting hook 300 under operation of the user. That is, when the user operates the adjusting operation member 130, he can either adjust the movable support 10, or drive the connecting hook 300. This can not only make the user’s operation more convenient, but also reduce the parts on the carrier 1 and simplify the structure. Of course, the disclosure is not limited thereto, and in another embodiment, the connecting hook 300 can also be operated by the user independently of the adjusting operation member 130.

[00224] It should be understood, the adjusting operation member 130 may be arranged to drive the connecting hook 300 to move toward the connected position and/or the non-connected position. In an embodiment, the adjusting operation member 130 is arranged to drive the connecting hook 300 to move toward the non-connected position, and at the same time, the connecting hook 300 is arranged to be driven by another member to move toward the connected position. For example, the carrier 1 may include a connecting hook reset elastic member 301, and the connecting hook reset elastic member 301 drives the connecting hook 300 to move toward the connected position sj],

[00225] Here, the connecting hook 300 which can be driven by the adjusting operation member 130 to move toward the non-connected position and can be driven by connecting hook reset elastic member 301 to move toward the connected position will be taken as an example for description.

[00226] As shown in Figs. 12, 27 and. 29, the connecting hook reset elastic member 301 may be an M elastic sheet arranged on the connecting hook 300, and the elastic sheet may abut against the carrier 1. [00227] When the user acts on the adjusting operation member 130, as shown in Fig. 29, the adjusting operation member 130 drives the connecting hook 300 while moving, such that the connecting hook 300 is pivoted toward the non-connected position, whereby the carrier 1 can be moved away from the carrier application device.

[00228] When the user no longer acts on the adjusting operation member 130, as shown in Fig. 27, the connecting hook 300 is pivoted toward the connected position under an elastic force of the elastic sheet 301 abutting against the carrier 1, whereby the carrier 1 can be connected to the carrier application device. In the meanwhile, the adjusting operation member 130 connected to the connecting hook 300 will be driven by the connecting hook 300 to return to the initial position.

[00229] Second Embodiment of Adjustment Device of Carrier

[00230] Figs. 31 to 42 show the second embodiment of the adjustment device of the carrier according to the disclosure, which is different from the embodiments of the adjustment device described above with reference to Figs. 7 to 9 mainly in that, an adjustment executing member 160 is used in the second embodiment to replace the adjusting operation member 130, and correspondingly, structure and driving mode of the movable positioning member 120 are changed in the second embodiment.

[00231] Specifically, the second embodiment of the adjustment device 100 may include an adjustment executing member 160, and the adjustment executing member 160 is arranged to be able to directly or indirectly drive the movable positioning member 120 to move toward a disengaged position.

[00232] In the embodiment shown in Figs. 31 to 35, the adjustment executing member 160 is an adjustment button arranged on the crossbar 11 between two movable supports 10. Since the crossbar 11 can be arranged below the movable supports 10 so as to be exposed from the lower part of the carrier 1, the user can easily touch and operate the adjustment button 160 arranged on the crossbar 11.

[00233] However, the disclosure is not limited thereto. The adjustment executing member 160 can take various structural forms, such as a handle, a wrench, a lever, a knob and the like, and can be arranged on the carrier 1 or at other positions, as long as it can drive the movable positioning member 120 to move toward the disengaged position.

[00234] In the second embodiment of the adjustment device 100, as shown in Figs. 34, 36, 37 and 39, the movable positioning member 120 is a positioning post movably arranged on a fixed seat 60, and the fixed seat 60 is fixed to the carrier 1. It should be understood, the movable positioning member 120 can be movably arranged on the carrier 1 without the fixed seat 60.

[00235] The at least two distance positioning members 110 are at least two positioning holes arranged on each of the movable supports 10. Moreover, the at least two positioning holes 110 are arranged at equal or unequal intervals along the moving direction of each of the movable supports 10.

[00236] The positioning post 120 is arranged to be able to move between the engaged position and the disengaged position. As shown in Figs. 34 and 36, the positioning post 120 is engaged with one of the positioning holes 110 when moving to the engaged position, thereby positioning the corresponding movable support 10 at this position. The positioning post 120 is disengaged from the positioning hole 110 when moving to the disengaged position, such that the movable support 10 is released from positioning and can move in respect with the carrier 1.

[00237] In order to realize the movement of the positioning post 120 arranged on the fixed seat 60 between the engaged position and the disengaged position, as shown in Figs. 37 and 39, the fixed seat 60 is provided with a positioning post guide part 601 for the positioning post 120 to move therein. Of course, the disclosure is not limited thereto. The fixed seat 60 may be provided with another structure to guide the movement of the positioning post 120 between the engaged position and the disengaged position. For example, one of the fixed seat 60 and the positioning post 120 may be provided with a pin roll, and the other one may be provided with a chute for the pin roll to slide thereon, and the movement of the positioning post 120 can be guided by cooperation between the pin roll and the chute.

[00238] In order to realize that the adjustment executing member 160 drives the positioning post 120, the second embodiment of the adjustment device 100 further includes a positioning member driving rod 122 and a traction member 170.

[00239] In the embodiments shown in Figs. 31, 34, 37 and 39, the fixed seat 60 is provided with a positioning member driving rod 122 capable of driving the positioning post 120 to move between the engaged position and the disengaged position. A pivoting end 122 A of the positioning member driving rod 122 is pivotably connected to the fixed seat 60, and a middle part of the positioning member driving rod 122 is movably connected to the positioning post 120, such that the pivoting movement of the positioning member driving rod 122 can bring the positioning post 120 to move.

[00240] More specifically, as shown in Figs. 37 and 39, the middle part of the positioning member driving rod 122 may be provided with a long-stripe-shaped driving rod slotted hole 122B. Correspondingly, a corresponding position of the positioning post 120 is provided with a positioning post pinhole 125. By inserting a pin roll (not shown) to pass through the driving rod slotted hole 122B and the positioning post pinhole 125, it can be realized that the pivoting movement of the positioning member driving rod 122 brings the positioning post 120 to move. In addition, in order to facilitate the movement of the pin roll, as shown in Figs. 37 and 39, the positioning post guide part 601 on the fixed seat 60 is also provided with a long stripe-shaped positioning post guide part slotted hole 601 A for the pin roll to pass through and move therein. Of course, the disclosure is not limited thereto, and the positioning member driving rod 122 can drive the positioning post 120 to move in other ways. For example, the positioning member driving rod 122 may be connected by a steel wire and drive the positioning post 120 to move.

[00241] The adjustment executing member 160 and the positioning member driving rod 122 are connected and driven by the traction member 170. As shown in Figs. 31 and 34, a first end of the traction member 170 is connected to the adjustment executing member 160, and a second end of the traction member 170 is connected to a free end 122C of the positioning member driving rod 122.

[00242] When the adjustment executing member 160, such as an adjustment button, is operated, it drives the positioning member driving rod 122 to be pivoted toward an disengaging direction via the traction member 170 (i.e., in Fig. 31, the free end 122C of the positioning member driving rod 122 moves downwardly), thereby driving the positioning post 120 to move toward the disengaged position.

[00243] It should be understood, although in the above-described embodiment, the adjustment executing member 160 indirectly drives the positioning post 120 to move toward the disengaged position via the traction member 170 and the positioning member driving rod 122, the adjustment executing member 160 may be arranged adjacent to the positioning post 120 and directly drives the positioning post 120.

[00244] In another embodiment, it is unnecessary to provide the positioning member driving rod 122, and the second end of the traction member 170 may be directly connected to the positioning post 120, such that the traction member 170 can directly drive the positioning post 120 to move toward the disengaged position.

[00245] In addition, the fixed seat 60 is also provided with a positioning member reset elastic member 123, and the positioning member reset elastic member 123 is arranged to directly or indirectly drive the positioning post 120 toward the engaged position to move. In the embodiments shown in Figs. 36, 37, 39, the positioning member reset elastic member 123 may be a positioning member reset torsion spring, and the positioning member reset torsion spring 123 is arranged to drive the positioning member driving rod 122 to be pivoted toward the engagement direction, thereby driving the positioning post 120 to move toward the engaged position. Of course, the positioning member reset elastic member 123 may be an elastic member adopting another structure, such as a spring or a hydraulic rod and the like arranged to directly drive the positioning post 120 to move toward the engaged position.

[00246] When preparing to connect the carrier 1 to the vehicle seat 2, the user can firstly make the movable supports 10 move to extend out in respect with the carrier 1, such that the anchor joint 20 is away from the carrier 1, which can facilitate the user to engage the anchor joint 20 with the corresponding accessory on the vehicle seat 2. After the engagement, the user needs to move the carrier 1 such that the front edge IE of the carrier 1 can abut against the back 22 of the vehicle seat 2, thereby ensuring that the carrier 1 is firmly connected to the vehicle seat 2. In this process, it is required to make the movable supports 10 be able to move and retract in respect with the carrier 1 such that the anchor joint 20 is adjacent to the carrier 1. However, at this time, it would be very inconvenient if the user needs to operate the adjustment executing member 160 all the time such that the adjustment executing member 160 drives the movable positioning member 120 to keep it in the disengaged position.

[00247] In order to facilitate the user to retract the movable support 10 without operating the adjustment executing member 160, in an embodiment, as shown in Fig. 36, an end of the positioning post 120 which is engaged with one of the positioning holes 110 is provided with a positioning post ramp 124. The positioning post ramp 124 is arranged such that when the movable support 10 receives an acting force to move toward the carrier 1, an edge of the positioning holes 110 engaged with the positioning post 120 will abut against the positioning post ramp 124, thereby pushing the positioning post 120 to move toward the disengaged position, until the positioning post 120 is disengaged from the positioning holes 110, whereby the movable support 10 can move in respect with the carrier 1. That is, the positioning post ramp 124 is arranged to face the edge of the positioning holes 110 closer to the anchor joint 20. Accordingly, when the anchor joint 20 receives an acting force toward the direction of the carrier 1 (e.g., the acting force is a reverse thrust received by the anchor joint 20 exerted by the corresponding accessory on the vehicle seat 2 when the carrier 1 is pushed toward the direction of the vehicle seat 2), the anchor joint 20 brings the movable supports 10 to move together toward the carrier 1, so the edge of the positioning holes 110 on the movable supports 10 will exert an abutting force on the positioning post ramp 124, thereby pushing the positioning post 120 to move toward the disengaged position.

[00248] Of course, the disclosure is not limited thereto, and in all embodiments of the disclosure, a positioning member clamping end 126 of the movable positioning member 120, which is engaged with one of the distance positioning members 110, may be provided with a positioning member ramp 126A. Moreover, the positioning member ramp 126A may be arranged in the same way as the positioning post ramp 124 described above. For example, in the embodiment shown in Fig. 66B, the movable positioning member 120 is a positioning hook pivotably arranged on the carrier 1, and the distance positioning members 110 are positioning holes arranged on the movable supports 10. Among them, the positioning member clamping end 126 of the positioning hook 120 engaged with one of the positioning holes 110 may be provided with a positioning member ramp 126A. The positioning member ramp 126A may be arranged such that when the movable supports 10 is received an acting force to move toward the carrier 1, the edge of the positioning holes 110 engaged with the positioning member clamping end 126 will abut against the positioning member ramp 126 A, thereby pushing the positioning hook 120 to be pivoted toward the disengaged position, until the positioning hook 120 is disengaged from the positioning holes 110, whereby the movable supports 10 can move in respect with the carrier 1.

[00249] In addition, since the movable supports 10 may move toward the carrier 1 when receiving an acting force toward the carrier 1 , and in the process of connecting the carrier 1 to the vehicle seat 2, the movable supports 10 and the anchor joint 20 connected thereto are easily subjected to the acting force toward the carrier 1 due to touching the vehicle seat 2 and the like, so the movable supports 10 may accidentally move and retract in respect with the carrier 1, which may be adverse to the installation of the carrier 1. In order to avoid this problem, in an embodiment, as shown in Figs. 34 and 40-42, each of the movable supports 10 may be provided with a support insertion hole 13 (see Figs. 34 and 40), and the carrier 1 is provided with a support insertion member 104 for the support insertion hole 13 to be inserted therein. When the support insertion member 104 is movably inserted into the support insertion hole 13, the movable supports 10 cannot move in respect with the carrier 1, thereby avoiding the movable supports 10 from accidentally moving to be retracted or extended in respect with the carrier 1.

[00250] In an embodiment, the support insertion hole 13 and the support insertion member 104 are arranged such that only when the corresponding movable support 10 moves to a point where the distance of the anchor joint 20 in respect with the carrier 1 is the largest, the support insertion member 104 can be inserted into the support insertion hole 13. Here, the movable support 10 is moved such that the distance of the anchor joint 20 in respect with the carrier 1 is the largest, which means that the movable support 10 extends the longest in respect with the carrier 1, which is to facilitate the user to engage the anchor joint 20 with the corresponding accessory on the vehicle seat 2. Afterward, the user can adjust the movable support 10 to an appropriate extension length.

[00251] In this embodiment, the support insertion member 104 may be arranged to be pivotably connected to the carrier 1 (see Figs. 34, 40 42), or pivotably connected to the inside of an insertion member housing 104B (see Fig. 41 Fig. 42), the insertion member housing 104B may be fixed to the carrier 1. Accordingly, the support insertion member 104 can be movably inserted into the support insertion hole 13 by a pivoting movement. However, the disclosure is not limited thereto, and the support insertion member 104 may be arranged to be translationally inserted into the support insertion hole 13.

[00252] In order to keep the support insertion member 104 inserted into the support insertion hole 13 without being accidentally separated, in an embodiment, as shown in Figs. 34 and 40, the carrier 1 or the insertion member housing 104B may be provided with an insertion member reset elastic member 104A, and the insertion member reset elastic member 104A is arranged to drive the support insertion member 104 to move toward the direction of being inserted into the support insertion hole 13. The insertion member reset elastic member 104A may be a suitable elastic member such as a torsion spring, a hydraulic rod and the like.

[00253] On the other hand, after the anchor joint 20 is engaged with the corresponding accessory on the vehicle seat 2, the user needs to allow the movable supports 10 to move to be retracted in respect with the carrier 1, and at this time, it is required to make the support insertion member 104 be inserted into the support insertion hole 13 be separated from the support insertion hole 13. Of course, the user can manually operate the support insertion member 104 to separate it from the support insertion hole 13.

[00254] In an embodiment, as shown in Figs. 34 and 42, the unlocking drive member 30 arranged on each of the movable supports 10 (structure and working principle of the unlocking drive member 30 are similar to the unlocking drive member 30 in the embodiment shown in Figs. 12 to 21) may be provided with a bulged part 33. The bulged part 33 is arranged such that when the unlocking drive member 30 is in the non-driving position, the bulged part 33 will not be exposed from the support insertion hole 13; and when the unlocking drive member 30 is not in the non-driving position, the bulged part 33 is exposed from the support insertion hole 13 and drives the support insertion member 104 to be separated from the support insertion hole 13, such that the support insertion member 104 cannot prevent the movable supports 10 from moving in respect with the carrier 1.

[00255] Specifically, on the one hand, when the user prepares to engage the anchor joint 20 with the corresponding accessory on the vehicle seat 2, the movable supports 10 can be moved to make the distance of the anchor joint 20 in respect with the carrier 1 be the largest, such that the support insertion member 104 can be inserted into the support insertion hole 13, thereby keeping the movable supports 10 in this position in respect with the carrier 1. In this process, the anchor joint 20 is in the unlocked state, and the unlocking drive member 30 is in the non-driving position, meanwhile, since the bulged part 33 on the unlocking drive member 30 will not be exposed from the support insertion hole 13, the support insertion member 104 will remain inserted in the support insertion hole 13, thereby preventing the movable supports 10 from moving to be retracted in respect with the carrier 1.

[00256] On the other hand, after the anchor joint 20 is engaged with the corresponding accessory on the vehicle seat 2, the anchor joint 20 is in the locked state, and the unlocking drive member 30 moves to a position other than the non-driving position. At this time, since the bulged part 33 on the unlocking drive member 30 is exposed from the support insertion hole 13 and drives the support insertion member 104 to be separated from the support insertion hole 13, the support insertion member 104 cannot prevent the movable supports 10 from moving in respect with the carrier 1. Thus, the movable supports 10 can move to be retracted in respect with the carrier 1, thereby facilitating the user to abut the front edge IE of the carrier 1 against the back 22 of the vehicle seat 2.

[00257] It should be understood, the above cooperating structures of the support insertion member 104 and the support insertion hole 13 can be applied to all embodiments of the adjustment device according to the disclosure. Particularly, if the top end of the movable positioning member 120 in this embodiment of the adjustment device is provided with a ramp similar to the positioning post ramp 124, then the above cooperating structures of the support insertion member 104 and the support insertion hole 13 can be used to prevent the movable supports 10 from accidentally moving to be retracted or extended in respect with the carrier 1. On the other hand, even if the top end of the movable positioning member 120 is not provided with a ramp similar to the positioning post ramp 124, the above cooperating structures of the support insertion member 104 and the support insertion hole 13 can be used as a second safety lock additionally to the first safety lock (i.e., the cooperating structures of the movable positioning member 120 and the distance positioning members 110).

[00258] In addition, it should be understood, positions of the support insertion member 104 and the support insertion hole 13 can be arranged according to actual requirements.

[00259] For example, in the embodiments shown in Figs. 34, 35 and 40-42, the support insertion holes 13 are arranged on opposite inner side walls of the two movable supports 10. Of course, the support insertion hole 13 may also be provided by one which is arranged on an inner side wall or outer side wall of only one of the movable supports 10. Accordingly, the support insertion member 104 can be arranged adjacent to the inner side wall or outer side wall of the movable support 10, so as to be inserted into the support insertion holes 13. Moreover, the bulged part 33 is arranged on a corresponding inner side or outer side of the unlocking drive member 30.

[00260] For yet another example, in the embodiment shown in Figs. 66A and 66B, the support insertion hole 13 are arranged on an upper wall of the movable support 10. Of course, the support insertion hole 13 may also be arranged on a lower wall of the movable support 10. Accordingly, the support insertion member 104 may be arranged adjacent to the upper wall or the lower wall of the movable support 10, so as to be inserted into the support insertion hole 13. Moreover, the bulged part 33 is arranged on a corresponding upper surface or lower surface of the unlocking drive member 30.

[00261] Second Embodiment of Unlocking Mechanism of Anchor Assembly [00262] Figs. 31 to 39also show the second embodiment of an unlocking mechanism of the anchor assembly according to the disclosure, which is different from the embodiment of the unlocking mechanism of the anchor assembly described above with reference to Figs. 12 to 21 mainly in that an unlocking execution member 130' is used in the second embodiment to replace the unlocking operation member 40, and correspondingly, driving structure and driving mode of the unlocking drive member 30 are changed in the second embodiment.

[00263] Specifically, in the second embodiment, the anchor assembly may include an unlocking execution member 130'. The unlocking execution member 130' is movably arranged on the carrier 1, and is arranged to directly or indirectly drive the unlocking drive member 30 to slide toward the non-driving position.

[00264] In the embodiment shown in Figs. 31 to 39, the unlocking execution member 130' is the same as the previously described adjusting operation member 130 in terms of its own structure and positional relationship in respect with the carrier 1, and the only difference is that the function of the previously described adjusting operation member 130 is to drive the positioning hook 120 to move toward the disengaged position, and the function of the unlocking execution member 130' in the second embodiment is to drive the unlocking drive member 30 to slide toward the non-driving position.

[00265] In the second embodiment, the anchor assembly may include a linked movement member 140. A first end 141 of the linked movement member 140 is connected to the unlocking execution member 130', and a second end 142 of the linked movement member 140 is directly or indirectly connected to the unlocking drive member 30, such that the unlocking execution member 130' drives the unlocking drive member 30 via the linked movement member 140.

[00266] In order to realize driving the unlocking drive member 30 to slide toward the non-driving position, in the second embodiment, as shown in Fig. 33, the unlocking drive member 30 is provided with a plurality of oblique teeth 32. Correspondingly, the anchor assembly includes an oblique teeth cooperative member 61 movably arranged on a fixed seat 60. The fixed seat 60 is fixed to the carrier 1. The oblique teeth cooperative member 61 is arranged to be able to move and abut against a ramp of one oblique teeth 32 of the plurality of oblique teeth 32 under driving of the linked movement member 140, thereby pushing the unlocking drive member 30 to slide toward the non-driving position. It should be understood, the oblique teeth cooperative member 61 can be movably arranged on the carrier 1 without the fixed seat 60. [00267] In order to realize that the oblique teeth cooperative member 61 arranged on the fixed seat 60 is movable, as shown in Figs. 37 and 39, the fixed seat 60 is provided with a cooperative member guide part 602 for the oblique teeth cooperative member 61 to move therein. Of course, the disclosure is not limited thereto. The fixed seat 60 can be provided with another structure to guide movement of the oblique teeth cooperative member 61. For example, one of the fixed seat 60 and the oblique teeth cooperative member 61 can be provided with a pin roll, and the other can be provided with a chute for the pin roll to slide thereon, so the movement of the oblique teeth cooperative member 61 can be guided by the cooperation between the pin roll and the chute.

[00268] In addition, as shown in Figs. 34 and 36, the unlocking drive member 30 is located inside the movable support 10, so the oblique teeth cooperative member 61 can move through the positioning holes 110 on the movable support 10 to abut against the oblique teeth 32 on the unlocking drive member 30. In an embodiment where the movable support 10 is not provided with the positioning holes 110, the movable support 10 may be provided with a penetrating hole (not shown) dedicated for the oblique teeth cooperative member 61 to move therethrough, or the movable support 10 may be arranged to expose a part of the unlocking drive member 30 with the oblique teeth 32, such that the oblique teeth cooperative member 61 can abut against the oblique teeth 32 of the unlocking drive member 30.

[00269] In the embodiments shown in Figs. 31, 33, 34, and 36-39, the same fixed seat 60 is adopted to arrange the oblique teeth cooperative member 61 and the positioning post 120, which is helpful for the production and assembly of the members. However, the disclosure is not limited thereto, and different fixed seats may be adopted to respectively arrange the oblique teeth cooperative member 61 and the positioning post 120. In addition, the oblique teeth cooperative member 61 can be movably arranged on the carrier 1 without the fixed seat 60.

[00270] In order to realize driving of the oblique teeth cooperative member 61, as shown in Figs. 33, 38 and 39, in the second embodiment, the anchor assembly further includes a cooperative member turntable 62 capable of driving the oblique teeth cooperative member 61. The cooperative member turntable 62 is rotatably arranged on the fixed seat 60. The linked movement member 140 may directly or indirectly drive the cooperative member turntable 62 to rotate toward a third rotation direction R3 (see Fig. 33), thereby driving the oblique teeth cooperative member 61 to move toward a direction for abutting against the oblique teeth 32. [00271] As shown in Fig. 37, a turntable rotating shaft 621 of the cooperative member turntable 62 is provided with a turntable torsion spring 622. The turntable torsion spring 622 is arranged to drive the cooperative member turntable 62 to rotate toward a fourth rotation direction R4 opposite to the third rotation direction R3 (see Figs. 33 and 38), thereby driving the oblique teeth cooperative member 61 to move toward a direction away from the oblique teeth 32.

[00272] After the unlocking drive member 30 moves to the non-driving position such that the anchor joint 20 is unlocked, the user does not operate the unlocking execution member 130' any longer, so the turntable torsion spring 622 will drive the cooperative member turntable 62 to rotate toward the fourth rotation direction R4, thereby driving the oblique teeth cooperative member 61 to move toward the direction away from the oblique teeth 32 until leaving the positioning holes 110, so as to avoid the oblique teeth cooperative member 61 to obstruct the movable supports 10 from moving in respect with the carrier 1 due to being inserted into the positioning holes 110.

[00273] In order to realize that the cooperative member turntable 62 drives the oblique teeth cooperative member 61, in the embodiment shown in Figs. 38 and 39, the oblique teeth cooperative member 61 is provided with a cooperative member driving hole 611 (see Fig. 39), and the cooperative member turntable 62 is provided with a turntable driving hole 623, furthermore, a turntable driving pin 624 passes through the cooperative member driving hole 611 on the oblique teeth cooperative member 61 and the turntable driving hole 623 on the cooperative member turntable 62, such that the cooperative member turntable 62 can drive the oblique teeth cooperative member 61. Among them, the turntable driving hole 623 may be designed with a larger size, such that in the process for the cooperative member turntable 62 to drive the oblique teeth cooperative member 61, the turntable driving pin 624 has enough moving space.

[00274] In addition, in order to facilitate the movement of the turntable driving pin 624, as shown in Figs. 37 and 39, the cooperative member guide part 602 on the fixed seat 60 has a long stripe-shaped cooperative member guide part slotted hole 602A from the turntable driving pin 624 to pass through and move therein. Of course, the disclosure is not limited thereto, and the cooperative member turntable 62 can also adopt other structures and drive the oblique teeth cooperative member 61 in other ways. For example, the cooperative member turntable 62 may be connected by a steel wire and drive the oblique teeth cooperative member 61 to move. [00275] In the second embodiment, as shown in Fig. 31, the anchor assembly may further include a bringing member 150 connected to the second end 142 of the linked movement member 140. The bringing member 150 is movably arranged on the carrier 1, and connected to the cooperative member turntable 62 via a turntable connecting member 63. The bringing member 150 and the turntable connecting member 63 are arranged to be able to transmit driving of the linked movement member 140 to the cooperative member turntable 62.

[00276] It should be understood, the bringing member 150 used in the second embodiment can be as same as the bringing member 150 previously described with reference to Figs. 7, 8, 23B and 25B in structure and working principle related to driving the connecting post 200. That is, the bringing member 150 and the connecting post 200 used in the second embodiment may also be arranged to drive each other to move, such that the connecting post 200 can be driven by the unlocking execution member 130'.

[00277] As shown in Figs. 33 and 34, the turntable connecting member 63 may be connected to a turntable connecting point 625 on the cooperative member turntable 62, such that the turntable connecting member 63 can drive the cooperative member turntable 62 toward a third rotation direction R3 to rotate (see Fig. 33).

[00278] In the embodiment shown in Figs. 38 and 39, the cooperative member turntable 62 is shaped approximately a half disk, which is to reduce the production materials and cost of the cooperative member turntable 62, and also to reduce weight of the cooperative member turntable 62 at the same time. It should be understood, the cooperative member turntable 62 may be shaped as a complete disk.

[00279] It should be understood, the second embodiment of the adjustment device of the carrier and the second embodiment of the unlocking mechanism of the anchor assembly previously described above can be used together, as shown in Figs. 31 to 36, but they can also be used separately.

[00280] Third Embodiment of Adjustment Device of Carrier

[00281] Figs. 43 to 46 show the third embodiment of the adjustment device of the carrier according to the disclosure, which is different from the embodiments of the adjustment device described above with reference to Figs. 7 to 9 mainly in that the adjusting operation member 130 is replaced by an anchor assembly operation member 40' in the third embodiment, and correspondingly, the third embodiment changes the driving mode of the movable positioning member 120.

[00282] Specifically, in the third embodiment, the anchor assembly may include a driving turntable 70 and the anchor assembly operation member 40'.

[00283] The driving turntable 70 is rotatably arranged on the movable supports 10, and is arranged such that the movable supports 10 can move in respect with the carrier 1 or unlock the anchor joint 20.

[00284] The anchor assembly operation member 40' is arranged to directly or indirectly drive the driving turntable 70 to rotate. In addition, in the embodiments shown in Figs. 43, 47 and 49, the anchor assembly operation member 40' is arranged near the crossbar 11 between the two movable supports 10, and the crossbar 11 may be arranged below the movable supports 10, so as to be exposed from the lower part of the carrier 1, such that the user can easily touch and operate the anchor assembly operation member 40' arranged near the crossbar 11. Of course, the disclosure is not limited thereto, and the anchor assembly operation member 40' can be arranged at other positions as long as it is convenient for the user to operate.

[00285] In the embodiment shown in Fig. 43, the anchor assembly operation member 40' may be connected to and drive the driving turntable 70 via a transmission member 50. However, the disclosure is not limited thereto, and the transmission member 50 may be omitted, so the anchor assembly operation member 40' may be directly connected to and drive the driving turntable 70.

[00286] As shown in Fig. 43, a middle part 51 of the transmission member 50 is pivotably connected to the movable supports 10, a first end 52 of the transmission member 50 is connected to the anchor assembly operation member 40', and a second end 53 of the transmission member is directly or indirectly connected to the driving turntable 70.

[00287] In the embodiment shown in Fig. 43, a latch 54 passes through the second end 53 of the transmission member 50, an arc-shaped slotted hole 12 on the movable support 10, and a long stripe-shaped turntable connecting hole 71 on the driving turntable 70 (see Figs. 48 and 50), such that the second end 53 of the transmission member 50 is connected to and drives the driving turntable 70 via the latch 54. In order to facilitate the second end 53 of the transmission member 50 to be pivoted toward the first rotation direction R1 or the second rotation direction R2, the slotted hole 12 on the movable support 10 is arranged as an arc-shaped strip slot, such that the latch 54 can slide in the slotted holes 12. In another embodiment, the latch 54 may be integrally formed with the second end 53 of the transmission member 50, and accordingly, the second end 53 of the transmission member 50 is directly connected to and drives the driving turntable 70.

[00288] The first end 52 of the transmission member 50 and the second end 53 can rotate around the rotary connection of the middle part 51.

[00289] When the user exerts an acting force on the anchor assembly operation member 40' toward the second rotation direction R2, the first end 52 of the transmission member 50 connected to the anchor assembly operation member 40' will be pivoted toward the second rotation direction R2 following the anchor assembly operation member 40' (see Fig. 46), so the second end 53 of the transmission member 50 connected to the driving turntable 70 is also pivoted toward the second rotation direction R2, whereby the second end 53 drives the driving turntable 70 to rotate toward a fifth rotation direction R5 (see Fig. 46).

[00290] When the user exerts an acting force on the anchor assembly operation member 40' toward the first rotation direction Rl, the first end 52 of the transmission member 50 connected to the anchor assembly operation member 40' will be pivoted toward the first rotation direction Rl following the anchor assembly operation member 40' (see Fig. 50), so the second end 53 of the transmission member 50 connected to the driving turntable 70 is also pivoted toward the first rotation direction Rl, whereby the second end 53 drives the driving turntable 70 to rotate toward a sixth rotation direction R6 (see Fig. 50).

[00291] Accordingly, when the user operates the anchor assembly operation member 40', the movement of the anchor assembly operation member 40' will be transmitted to the driving turntable 70 via the transmission member 50.

[00292] In order to realize that the driving turntable 70 can make the movable supports 10 move in respect with the carrier 1, the anchor assembly includes: at least two distance positioning members 110, arranged on the movable support 10; a movable positioning member 120, arranged on the carrier 1, and can move between an engaged position and a disengaged position. Among them, the movable positioning member 120 is engaged with one of the distance positioning members 110 in the engaged position, and the movable positioning member 120 is disengaged from the distance positioning member 110 in the disengaged position.

[00293] In the embodiment shown in Figs. 45 and 46, the movable positioning member 120 is a positioning hook pivotably arranged on the carrier 1, and the distance positioning members 110 are at least two positioning holes arranged on the movable support 10. Of course, the disclosure is not limited thereto, and the movable positioning member 120 and the distance positioning members 110 may be, for example, two members cooperating in concave and convex, or pin rolls, slotted holes and the like.

[00294] As shown in Figs. 45 and 46, the anchor assembly further includes a first driving connection member 81. The first driving connection member 81 is connected between the driving turntable 70 and the movable positioning member 120, such that when the driving turntable 70 rotates toward the fifth rotation direction R5 under driving of the anchor assembly operation member 40' (see Fig. 46), the driving turntable 70 drives the positioning hook 120 to move toward the disengaged position via the first driving connection member 81, such that the movable supports 10 can move in respect with the carrier 1.

[00295] Third Embodiment of Unlocking Mechanism of Anchor Assembly

[00296] Figs. 47 to 50 show the third embodiment of the unlocking mechanism of the anchor assembly according to the disclosure, which is different from the embodiments of the unlocking mechanism of the anchor assembly described above with reference to Figs. 12 to 21 mainly in that the unlocking drive member 30 is replaced by a turntable 70 and a second driving connection member 82 in the third embodiment.

[00297] In order to realize that the driving turntable 70 can unlock the anchor joint 20, the anchor assembly includes a sliding member 22. The sliding member 22 is arranged in the anchor joint 20 to be capable of sliding between a driving position and a non-driving position, moreover, the sliding member 22 is arranged such that when the sliding member 22 slides to the driving position, the anchor joint 20 can be kept in a locked state, and when the sliding member 22 slides to the non-driving position, the anchor joint 20 is allowed to enter an unlocked state. It should be understood, the sliding member 22 and the anchor joint 20 used in the third embodiment may be as same in structure and working principle as the sliding member 22 and the anchor joint 20 previously described with reference to Figs. 15 to 21.

[00298] As shown in Figs. 48 and 50, the anchor assembly further includes a second driving connection member 82. the second driving connection member 82 is connected between the driving turntable 70 and the sliding member 22, such that when the driving turntable 70 rotates toward a sixth rotation direction R6 opposite to the fifth rotation direction R5, the driving turntable 70 drives the sliding member 22 to slide toward the non-driving position via the second driving connection member 82 (see Fig. 50), thereby unlocking the anchor joint 20.

[00299] The first driving connection member 81 and the second driving connection member 82 each can be a flexible member made of various materials, such as silk, thread, rope and the like, or a rigid member in the form of a rod, a plate or a block.

[00300] It should be understood, the third embodiment of the adjustment device of the carrier and the third embodiment of the unlocking mechanism of the anchor assembly described above can be used together, as shown in Figs. 45 and 46, or can be used separately.

[00301] In the case that third embodiment of the adjustment device of the carrier and the third embodiment of the unlocking mechanism of the anchor assembly are used together, and the first driving connection member 81 and the second driving connection member 82 are flexible members, in an embodiment, the first driving connection member 81 and the second driving connection member 82 may be two parts of a same driving connection member. That is, the first driving connection member 81 and the second driving connection member 82 may be, for example, a same steel wire, and a middle part of the steel wire is connected to the turntable connecting point 72 on the driving turntable 70 (see Figs. 45, 46, 48 and 50, in which the first driving connection member 81 is not shown in Figs. 48 and 50 for sake of simplicity). In fact, in this embodiment, the third embodiment selectively realizes the movement of the movable supports 10 in respect with the carrier 1 and the unlocking of the anchor joint 20 by using the anchor assembly operation member 40', the driving turntable 70, and the driving connection member.

[00302] Fourth Embodiment of Adjustment Device of Carrier and Unlocking Mechanism of Anchor Assembly

[00303] Figs. 51 to 62 show the fourth embodiment of the adjustment device of the carrier and the unlocking mechanism of the anchor assembly according to the disclosure, which is different from the embodiments of the adjustment device described above with reference to Figs. 7 to 9 and the unlocking mechanism of the anchor assembly described above with reference to Figs. 12 to 21 mainly in that the movable support 10 moves in respect with the carrier 1 and the anchor joint 20 is unlocked are realized in the fourth embodiment by using an anchor assembly operation member 40' and a functional drive member 90.

[00304] Specifically, in the fourth embodiment, the anchor assembly may include a functional drive member 90 and an anchor assembly operation member 40'.

[00305] As shown in Figs. 53, 55, 57 and 61, the functional drive member 90 is movably arranged on the movable supports 10, and is provided with a guide slot 91 consisting of a parallel slot 91 A and an inclined slot 91B which are communicated with each other. Among them, an extending direction of the parallel slot 91 A is parallel to the moving direction of the movable support 10, and an extending direction of the inclined slot 91 B is inclined to the moving direction of the movable supports 10. The parallel slot 91 A and the inclined slot 91B have a converged point 911, the parallel slot 91 A has a parallel slot end 912 away from the converged point 911, and the inclined slot 91 B has an inclined slot end 913 away from the converged point 911.

[00306] Correspondingly, the movable support 10 is provided with a guide post 14 passing through the guide slot 91.

[00307] Through the cooperation of the guide slot 91 and the guide post 14, the functional drive member 90 can either move in respect with the movable support 10 parallel to the moving direction of the movable supports 10 to realize unlocking of the anchor joint 20, or move in respect with the movable support 10 inclined to the moving direction of the movable supports 10 to realize moving of the movable supports 10 in respect with the carrier 1.

[00308] More specifically, on the one hand, in order to unlocking of the anchor joint 20, the guide slot 91 and the guide post 14 are arranged such that when the functional drive member 90 moves to make the guide post 14 locate at the parallel slot end 912, as shown in Fig. 55, the functional drive member 90 moves to the non-driving position at this time, and through an unlocking link rod 27 connected between the functional drive member 90 and the sliding member 22, the functional drive member 90 drives the sliding member 22 also to move to the non-driving position, and accordingly, the anchor joint 20 is allowed to enter the unlocked state. It should be understood, the sliding member 22 and the anchor joint 20 used in the fourth embodiment may be as same in structure and working principle as the sliding member 22 and the anchor joint 20 previously described with reference to Figs. 15 to 21. In addition, in other embodiment, the functional drive member 90 may be connected to and drive the sliding member 22 by other members, or alternatively, the functional drive member 90 may be directly connected to and drive the sliding member 22.

[00309] In the embodiment shown in Fig. 62, the unlocking link rod 27 has a body part 271 and two connecting arms 272 extending from the body part 271. Among them, the body part 271 is provided with a body part connecting hole 271 A for connecting to the functional drive member 90. The two connecting arms 272 serve to be connected to the sliding member 22. Of course, the unlocking link rod 27 can take other suitable structure.

[00310] On the other hand, in order to realize moving and positioning of the movable supports 10 in respect with the carrier 1, as shown in Figs. 59 and 60, the anchor assembly includes: at least two distance positioning members 110, arranged on the movable support 10; and a movable positioning member 120, arranged on the carrier 1 and can move between the engaged position and the disengaged position. Among them, the movable positioning member 120 is engaged with one of the distance positioning members 110 when in the engaged position, thereby preventing the movable supports 10 from moving in respect with the carrier 1 ; and the movable positioning member 120 is disengaged from the distance positioning members 110 when in the disengaged position, thereby allowing the movable supports 10 to move in respect with the carrier 1.

[00311] In the embodiment shown in Figs. 59 and 60, the movable positioning member 120 is a positioning post movably arranged on the carrier 1 with a positioning member reset elastic member 123 arranged below positioning post. The positioning member reset elastic member 123 is arranged to drive the movable positioning member 120 to move toward the engaged position. However, the disclosure is not limited thereto, and the movable positioning member 120 may take other structures.

[00312] Correspondingly, the functional drive member 90 is provided at least two pushing bulges 92, and the pushing bulges 92 are arranged such that when the functional drive member 90 moves to make the guide post 14 be at the inclined slot end 913, as shown in Fig. 60, one of the pushing bulges 92 can push the movable positioning member 120 to the disengaged position.

[00313] That is, the guide slot 91 and the guide post 14 are arranged such that when the functional drive member 90 moves to make the guide post 14 be at the inclined slot end 913, as shown in Fig. 57, the functional drive member 90 moves substantially in a direction perpendicular to the moving direction of the movable supports 10, i.e., the functional drive member 90 moves toward the downward direction in Fig. 57, thereby urging one of the pushing bulges 92 of the functional drive member 90 to contact the movable positioning member 120 and pushing the movable positioning member 120 to the disengaged position.

[00314] In an embodiment, the number and position of the pushing bulges 92 of the functional drive member 90 may be arranged to be corresponding to the number and position of the distance positioning members 110, such that when the functional drive member 90 moves to make the guide post 14 be at inclined slot end 913, the pushing bulges 92 can enter the distance positioning members 110 one by one, so as to ensure that the movable positioning member 120 are pushed to the disengaged position. Of course, the number of the pushing bulges 92 of the functional drive member 90 may also be arranged to be less than the number of the distance positioning members 110.

[00315] In addition, as shown in Fig. 61, the end of the functional drive member 90 is provided with a long stripe-shaped avoidance slot 93 for connecting to the unlocking link rod 27, and an extension direction of the avoidance slot 93 is parallel to the extending direction of the inclined slot 9 IB. A pin roll can pass through the body part connecting hole 271 A on the unlocking link rod 27 and the avoidance slot 93 on the functional drive member 90, thereby connecting the functional drive member 90 to the unlocking link rod 27. Accordingly, when the functional drive member 90 moves in respect with the movable supports 10 in a moving direction inclined to the movable supports 10, it will not be interfered by the unlocking link rod 27.

[00316] The anchor assembly operation member 40' adopted in the fourth embodiment is as same in structure and working principle as the anchor assembly operation member 40' adopted in the third embodiment, except that the anchor assembly operation member 40' in the fourth embodiment is arranged to directly or indirectly drive the functional drive member 90 to move on the movable support 10.

[00317] Similar to the third embodiment, the anchor assembly operation member 40' in the fourth embodiment can be connected to and drive the functional drive member 90 via a transmission member 50. However, the disclosure is not limited thereto, the transmission member 50 may be omitted, and the anchor assembly operation member 40' may be directly connected to and drive the functional drive member 90.

[00318] As shown in Fig. 51, the middle part 51 of the transmission member 50 is pivotably connected to the movable supports 10, the first end 52 of the transmission member 50 is connected to the anchor assembly operation member 40', and the second end 53 of the transmission member is directly or indirectly connected to the functional drive member 90 (not shown in Fig. 51).

[00319] In the embodiment shown in Fig. 51, a latch 54 passes through the second end 53 of the transmission member 50, the arc-shaped slotted hole 12 of the movable supports 10 and the long stripe-shaped functional drive member connecting hole 94 of the functional drive member 90 (see Figs. 53, 55, 57 and 61), such that the second end 53 of the transmission member 50 is connected to and drives the functional drive member 90 via the latch 54. In order to facilitate the second end 53 of the transmission member 50 to be pivoted toward the first rotation direction Rl or the second rotation direction R2, the slotted hole 12 on the movable supports 10 is arranged as an arc-shaped strip slot, such that the latch 54 can slide in the slotted hole 12. In another embodiment, the latch 54 may be integrally formed with the second end 53 of the transmission member 50, whereby the second end 53 of the transmission member 50 is directly connected to and drives the functional drive member 90.

[00320] The first end 52 and the second end 53 of the transmission member 50 can rotate around the rotary connection of the middle part 51.

[00321] When the user exerts an acting force on the anchor assembly operation member 40' toward the second rotation direction R2, the first end 52 of the transmission member 50 connected to the anchor assembly operation member 40' is pivoted toward the second rotation direction R2 following the anchor assembly operation member 40' (see Fig. 55), then the second end 53 of the transmission member 50 connected to the functional drive member 90 is also pivoted toward the second rotation direction R2, and accordingly, the second end 53 drives the functional drive member 90 to move to make the guide post 14 be at the parallel slot end 912 (see Fig. 55), thereby realizing the unlocking of the anchor joint 20.

[00322] When the user exerts an acting force on the anchor assembly operation member 40' toward the first rotation direction Rl, the first end 52 of the transmission member 50 connected to the anchor assembly operation member 40' is pivoted toward the first rotation direction Rl following the anchor assembly operation member 40' (see Fig. 57), then the second end 53 of the transmission member 50 connected to the functional drive member 90 is also pivoted toward the first rotation direction Rl, whereby the second end 53 drives the functional drive member 90 such that the guide post 14 is at the inclined slot end 913 (see Fig. 57), thereby realizing the movement of the movable supports 10 in respect with the carrier 1.

[00323] Fifth Embodiment of Adjustment Device of Carrier

[00324] Figs. 63 to 71 show the fifth embodiment of the adjustment device of the carrier according to the disclosure, which is different from the embodiments of the adjustment device described above with reference to Figs. 7 to 9 mainly in that an adjustment executing member 180 is used in the fifth embodiment to replace the adjusting operation member 130, and correspondingly, the connecting member between the adjustment executing member 180 and the movable positioning member 120 is omitted in the fifth embodiment.

[00325] Specifically, the fifth embodiment of the adjustment device 100 may include an adjustment executing member 180. The adjustment executing member 180 is arranged to be directly connected with or integrally formed with the movable positioning member 120, and can drive the movable positioning member 120 to move toward the disengaged position. That is, there is no other connecting member between the adjustment executing member 180 and the movable positioning member 120, thus the manufacturing and installation costs of the adjustment device 100 can be reduced.

[00326] In the embodiments shown in Figs. 66A, 66B, 69 and 70, the movable positioning member 120 is arranged in the carrier 1, and the movable positioning member 120 has a positioning member connection part 127 exposed outside the carrier 1 (see Figs. 69 and 70), such that the adjustment executing member 180 is connected to the positioning member connection part 127 outside the carrier 1, thereby facilitating the user to drive the movable positioning member 120 in the carrier 1 by operating the adjustment executing member 180 outside the carrier 1.

[00327] In another embodiment, the movable positioning member 120 may not be provided with the positioning member connection part 127, instead, the adjustment executing member 180 may be provided with a part that can be inserted into the carrier 1 and connected to the movable positioning member 120.

[00328] In yet another embodiment, the movable positioning member 120 can be integrally formed with the adjustment executing member 180, for example, the positioning member connection part 127 of the movable positioning member 120 exposed outside the carrier 1 can be used as the adjustment executing member 180.

[00329] In addition, although the movable positioning member 120 is shown as being a positioning hook pivotably arranged on the carrier 1, the movable positioning member 120 of this embodiment can take another form such as a positioning post and the like.

[00330] Although the adjustment executing member 180 is shown in a form of a sliding cover, the adjustment executing member 180 can take various structural forms such as a handle, a wrench, a lever, a button, a knob and the like. Moreover, the movement of the adjustment executing member 180 on the carrier 1 may be performed in various forms, such as sliding, pivoting or screwing and the like, as long as it can drive the movable positioning member 120. For example, when the movable positioning member 120 is a positioning hook pivotably arranged on the carrier 1, the adjustment executing member 180 can be a knob rotating coaxially with the positioning hook 120, and the knob can be arranged such that when the knob is operated by the user to rotate, it can bring the positioning hook 120 to be pivoted toward the disengaged position.

[00331] In the embodiment shown in Figs. 68 to 70, the carrier 1 has an opening 105 (see Fig. 70) at a position where the movable positioning member 120 is located, such that the movable positioning member 120 is exposed outside the carrier 1 via the opening 105, thereby facilitating the connection between the movable positioning member 120 and the adjustment executing member 180. The opening 105 may be sized to expose most of the movable positioning member 120, as shown in Fig. 70. The opening 105 may also be sized to expose only a small part of the movable positioning member 120, e.g., only the positioning member connection part 127.

[00332] In order to prevent dust or sundries from entering the interior of the carrier 1 via the opening 105 to affect the operation of the movable positioning member 120, and also to make the carrier 1 more aesthetically pleasing at the same time, as shown in Figs. 68 and 69, the carrier 1 may be provided with a decorative cover 106 covering the opening 105. Of course, if the opening 105 is sized to expose only the positioning member connection part 127 of the movable positioning member 120, it is unnecessary to provide the decorative cover 106.

[00333] As shown in Figs. 69 and 71, the decorative cover 106 is provided with a penetrative decorative cover long slot 106A, such that the positioning member connection part 127 is exposed outside the carrier 1 by passing through the decorative cover long slot 106A and can slide along the decorative cover long slot 106A. The movement of the movable positioning member 120 between the engaged position and the disengaged position can be limited by the positioning member connection part 127 sliding along the decorative cover long slot 106A.

[00334] In addition, in order to prevent the movable positioning member 120 from swinging during the movement, at least one of the carrier 1 and the decorative cover 106 can be provided with a supporting rib 107 for supporting the movable positioning member 120, as shown in Figs. 70 and 71, so as to ensure the movement of the movable positioning member 120 to be more stable.

[00335] As shown in Fig. 66B, the carrier 1 may also be provided with a positioning member reset torsion spring 123, and the positioning member reset torsion spring 123 is arranged to drive the movable positioning member 120 to move toward the engaged position. Accordingly, when the user does not operate the adjustment executing member 180, the movable positioning member 120 will move to the engaged position to be engaged with one of the distance positioning members 110 under driving of the positioning member reset torsion spring 123.

[00336] In the embodiment shown in Fig. 71, the decorative cover 106 may be provided with a torsion spring post 106B for the positioning member reset torsion spring 123 to be arranged thereon. Of course, the positioning member reset torsion spring 123 can be an elastic member adopted another structure, such as a spring or a hydraulic rod and the like, to drive the movable positioning member 120 to move toward the engaged position.

[00337] In the embodiment shown in Fig. 67, in the case that there two movable positioning members 120 provided and the two movable positioning members 120 are respectively cooperating with two movable supports 10, a positioning member linked movement rod 128 may be connected between the two movable positioning members 120. The positioning member linked movement rod 128 is arranged such that one of the movable positioning members 120 can bring the other movable positioning member 120 to move synchronously via the positioning member linked movement rod 128. Thus, the user only needs to drive one of the movable positioning members 120, the two movable positioning members 120 can move synchronously.

[00338] As shown in Figs. 63, 64 and 68-70, in order to conveniently drive the movable positioning members 120, the adjustment executing member 180 is arranged on an outer surface of a supporting seat ID under a side part 1C of the carrier 1, such that the user can operate it easily. In an embodiment, two adjustment executing members 180 are respectively arranged on the outer side surfaces of two supporting seats ID on two sides of the carrier 1. Thus, when the user operates the adjustment executing member 180 on either side of the carrier 1 to drive one of the movable positioning members 120, by the positioning member linked movement rod 128 connected between the two movable positioning members 120, the two movable positioning members 120 can move synchronously, which is convenient for the user to use. Of course, the user can also operate the two adjustment executing members 180 on both sides of the carrier 1 with both hands. In yet another embodiment, only one the adjustment executing member 180 is arranged on the outer surface of one supporting seat ID on one side of the carrier 1, such that manufacturing and installation costs can be reduced. Thus, when the user operates the one adjustment executing member 180 to drive the movable positioning members 120, by the positioning member linked movement rod 128 connected between the two movable positioning members 120, the two movable positioning members 120 can move synchronously.

[00339] Fifth Embodiment of Unlocking Mechanism of Anchor Assembly

[00340] Fig. 72 shows the fifth embodiment of the unlocking mechanism of the anchor assembly according to the disclosure, which is different from the second embodiment of the unlocking mechanism of the anchor assembly described above with reference to Figs. 31 to 39 mainly in that the intermediate members between the unlocking execution member 130' and the unlocking drive member 30 in the fifth embodiment are greatly reduced, thereby reducing the manufacturing and installation costs of the unlocking mechanism of the anchor assembly.

[00341] Specifically, the unlocking execution member 130' in the fifth embodiment is as same as the unlocking execution member 130' described in the second embodiment in terms of its own structure and positional relationship in respect with the carrier 1.

[00342] In an embodiment, only the linked movement member 140 is provided between the unlocking execution member 130' and the unlocking drive member 30, i.e., the first end 141 of the linked movement member 140 is connected to the unlocking execution member 130', and the second end 142 is directly connected to the unlocking drive member 30. When the user operates the unlocking execution member 130', the unlocking execution member 130' drives the unlocking drive member 30 to slide toward the non-driving position via the linked movement member 140.

[00343] In yet another embodiment, in order to enable the unlocking execution member 130', in the meantime driving the unlocking drive member 30 to move to the non-driving position to unlock the anchor joint 20, also drive the connecting post 200 to move to the retracted position such that the carrier 1 can move away from the carrier application device, as shown in Fig. 72, there is not only a linked movement member 140 with its first end 141 connected to the unlocking execution member 130' is provided between the unlocking execution member 130' and the unlocking drive member 30, but also a bringing member 150 connected to the second end 142 of the linked movement member 140 is provided. The bringing member 150 is movably arranged on the carrier 1, and is connected to the unlocking drive member 30 via a driving member connecting member 64. The bringing member 150 and the driving member connecting member 64 are arranged to be able to transmit driving of the linked movement member 140 to the unlocking drive member 30. Thus, when the user operates the unlocking execution member 130', the unlocking execution member 130' drives the unlocking drive member 30 to slide toward the non-driving position via the linked movement member 140, the bringing member 150, and the driving member connecting member 64.

[00344] It should be understood, the bringing member 150 used in the fifth embodiment can be substantially as same as the bringing member 150 described above with reference to Figs. 6, 7, Fig. 8, Figs. 23B and 25B in terms of structure and working principle related to driving the above connecting post 200. That is, the bringing member 150 and the connecting post 200 used in the fifth embodiment can be can also be arranged to drive each other to move, such that the connecting post 200 can be driven by the unlocking execution member 130'.

[00345] Base for Placing Carrier

[00346] In order to facilitate the user to connect the carrier 1 to the vehicle seat 2 shown in Fig.

1, the disclosure further provides another scheme, i.e., as shown in Fig. 73, the carrier 1 is connected to the vehicle seat 2 by a base 400.

[00347] The base 400 according to the disclosure may be connected to the vehicle seat 2 in advance by a conventional means such as a safety belt or ISOFIX and the like. Thus, when the carrier 1 is connected to or moved away from the base 400, that is, when the carrier 1 is connected to or moved away from the vehicle seat 2, this scheme can greatly improve the convenience of connecting or removing the carrier 1 to/from the vehicle seat 2.

[00348] It should be understood, the base 400 according to the disclosure can not only serve to place the carrier 1 including the anchor assembly, but also serve to place the carrier without the anchor assembly.

[00349] If the base 400 serve to place the carrier 1 including the anchor assembly as mentioned above, as shown in Figs. 75A, 75B, 76A and 76B, the base 400 is provided with an avoidance space 480. The avoidance space 480 may be arranged inside a front side of the base 400 at a position corresponding to the anchor assembly of the carrier 1. For example, the avoidance space 480 may be located between two side walls of a front and two base bulged parts 430 (will be described later) of the base 400. Thus, when the carrier 1 is placed on the base 400, the avoidance space 480 can accommodate the anchor assembly of the carrier 1. For example, the avoidance space 480 may be a space formed among two side walls of the front and the two base bulged parts 430 (will be described later) of the base 400 and an upper surface of the base 400. In order to ensure that a width of the avoidance space 480 is sufficient to accommodate the anchor assembly, as shown in Figs. 76A and 76B, a recession 482 may be formed on each of the side walls of the base 400 forming the avoidance space 480, and the recessions 482 extend downward from tops of the side walls to middle parts of the side walls. Thus, when the carrier 1 is placed on the base 400, the avoidance space 480 can accommodate the anchor assembly of the carrier 1. Before the carrier 1 is placed on the base 400, the anchor assembly can be adjusted to an appropriate extension length according to the situation of the avoidance space 480, for example, the extension length can be adjusted to be the shortest.

[00350] Of course, if the base 400 is used to place a carrier which does not include an anchor assembly, it is unnecessary for the base 400 to be provided with the avoidance space 480.

[00351] Figs. 73 to 82 show a first embodiment of the base 400 according to the disclosure for placing the carrier 1. For the convenience of description, as mentioned above, the direction for the backrest 1A in the carrier 1 to face is defined as front and the direction for it to face back is defined as back, and the left and right direction of the carrier 1 is defined as lateral, as shown in Figs. 73 to 77. It should be understood, positional terms such as “front,” “rear” and “lateral” are only used for clarity and convenience of description, rather than limitations of the disclosure.

[00352] In an embodiment, as shown in Figs. 75A, 75B and 76A-76B, the base 400 according to the disclosure includes a base engagement member 410 and a base operating member 420. Among them, the base engagement member 410 is used to engage the carrier 1, and the base operating member 420 is used to drive the base engagement member 410.

[00353] Hereinafter, the base engagement member 410 and its related components will be firstly described in detail.

[00354] As shown in Figs. 75A, 76A and 77-79, the base engagement member 410 on the base 400 is arranged to be movable between an engaged position and a non-engaged position. Among them, the base engagement member 410 can be engaged with a carrier engaging member 108 (see Fig. 74) arranged on the carrier 1 in the engaged position, thereby connecting the carrier 1 to the base 400, as shown in Fig. 73; moreover, the base engagement member 410 can be disengaged from the carrier engaging member 108 in the non-engaged position, thereby allowing the carrier 1 to move away from the base 400.

[00355] As shown in Fig. 77, after the base engagement member 410 moves to the non-engaged position under driving of the base operating member 420, it can return to the engaged position by a base elastic member 450. The base elastic member 450 is arranged to drive the base engagement member 410 to move toward the engaged position. In the embodiment shown in Fig. 77, the base elastic member 450 is a torsion spring. However, the base elastic member 450 may take another form of an elastic member such as a compression spring, a hydraulic rod and the like, as long as it can drive the base engagement member 410 to move toward the engaged position. In addition, it should be understood, the base elastic member 450 is not necessary for the disclosure, and the base engagement member 410 can be arranged to return to the engaged position under driving of the base operating member 420.

[00356] In the process for the user to place the carrier 1 on the base 400, in order to facilitate the user to move the base engagement member 410 to the non-engaged position without operating the base operating member 420, in the embodiment shown in Figs. 75A to 77, an end of the base engagement member 410 engaged with the carrier engaging member 108is provided with an engaging member ramp 413. The engaging member ramp 413 is arranged such that when the base engagement member 410 is ready to engage with the carrier engaging member 108, the carrier engaging member 108 can abut against the engaging member ramp 413, thereby pushing the base engagement member 410 to move toward the non-engaged position, thus making it more convenient for the user.

[00357] Referring to Fig. 74, in an embodiment, the carrier engaging member 108 may be a carrier engagement rod arranged on each of the supporting seats ID of the carrier 1. The base engagement member 410 may be a base engagement hook (see Figs. 75A to 77) pivotably arranged on the base 400. By engaging the carrier engagement rod 108 to the base engagement hook 410 or disengaging from the base engagement hook 410, it is easy to realize that the carrier 1 is connected to or moved away from the base 400.

[00358] In this embodiment, as shown in Fig. 77, an end of a front base engagement hook 410A (will be described later) engaged with the carrier engagement rod 108 is provided with an engaging member ramp 413. The engaging member ramp 413 is inclined in respect with the horizontal direction, such that when the front base engagement hook 410A is ready is ready to engage with the carrier engagement rod 108, the carrier engagement rod 108 can abut against the engaging member ramp 413, thereby generating a pivoting moment to the front base engagement hook 410A, and pushing the front base engagement hook 410A to be pivoted a the seventh rotation direction R7 to reach the non-engaged position. Correspondingly, as shown in Fig. 77, an end of a rear base engagement hook 41 OB (will be described later) engaged with the carrier engagement rod 108 may also be provided with an engaging member ramp 413. The engaging member ramp 413 is inclined in respect with the horizontal direction, such that when the rear base engagement hook 41 OB is ready to engage with the carrier engagement rod 108, the carrier engagement rod 108 can abut against the engaging member ramp 413, thereby generating a pivoting moment to the rear base engagement hook 41 OB, and pushing the rear base engagement hook 41 OB to be pivoted toward an eighth rotation direction R8 to reach the non-engaged position. It should be understood, in this embodiment, since the direction in which the front base engagement hook 410A is pivoted toward the non-engaged position (i.e., the seventh rotation direction R7) is different from the direction in which the rear base engagement hook 41 OB is pivoted toward the non-engaged position (i.e., the eight rotation direction R8), the inclination direction of the engaging member ramp 413 of the front base engagement hook 410A is also different from that of the engaging member ramp 413 of the rear base engagement hook 41 OB. However, if the front base engagement hook 410A and the rear base engagement hook 41 OB are arranged in the same direction to be pivoted toward the non-engaged position, the inclined direction of the engaging member ramp 413 of the front base engagement hook 410A may be arranged as same as that of the engaging member ramp 413 of the rear base engagement hook 410B.

[00359] In the embodiment shown in Fig. 74, the carrier engagement rod 108 is arranged to extend along a lateral direction perpendicular to the front-rear direction of the carrier 1. It should be understood, the carrier engagement rod 108 can also be arranged to extend along the front-rear direction of the carrier 1, and in such case, the position of the base engagement hook 410 and its engagement direction with the carrier engagement rod 108 need to be adjusted accordingly.

[00360] In the embodiment shown in Fig. 77, the base engagement hook 410 is pivotably connected to an engaging hook fixed seat 411, and the engaging hook fixed seat 411 is fixed to the base 400. In other embodiments, the base engagement hook 410 may also be directly connected to the base 400. In addition, the base engagement hook 410 is not limited to be pivotable, and may also be adopted to be slidable.

[00361] Of course, the disclosure is not limited thereto. The carrier engaging member 108 and the base engagement member 410 according to the disclosure may adopt other engaging members. For example, the carrier engaging member 108 may be an engaging hole arranged on the carrier 1, and the base engagement member 410 may be an engaging pin which can be movably inserted into the engaging hole.

[00362] In order to better place the carrier 1 in the base 400, in the embodiment shown in Figs. 75A to 76B, the base 400 may have base bulged parts 430 arranged on a surface thereof contacting with the carrier 1, and each of the base bulges 430 is provided with a base groove 431 capable of accommodating the carrier engagement rod 108. Moreover, the base engagement hook 410 is at least partially movably arranged in the base groove 431 and is arranged such that the base engagement hook 410 can lock the carrier engagement rod 108 inside the base groove 431 when in the engaged position; and the base engagement member 410 allows the carrier engagement rod 108 to enter or leave the base groove 431 when in the non-engaged position.

[00363] In order to more firmly place the carrier 1 in the base 400, a plurality of engaging points may be arranged between the carrier 1 and the base 400, so as to ensure that the carrier Iwill not be unstable such as overturning or swinging after the carrier 1 and the base 400 are connected.

[00364] In the embodiment shown in Figs. 75A to 79, the base engagement member 410 may include a front base engagement member 410A and a rear base engagement member 410B separated by a certain distance along the front-rear direction of the base 400. Among them, the front base engagement member 410A is located at a front of the base 400, and the rear base engagement member 410A is located at a rear of the base 400. Correspondingly, as shown in Fig. 74, the carrier engaging member 108 may include a front carrier engaging member 108A and a rear carrier engaging member 108B separated by a certain distance along the front-rear direction of the carrier 1. Positions of the front carrier engaging member 108 A and the rear carrier engaging member 108B are respectively corresponding to positions of the front base engagement member 410A and the rear base engagement member 410B. Such configuration can avoid the carrier 1 from turning over in the front-rear direction on the base 400.

[00365] Further, the front base engagement member 410A and the rear base engagement member 410B may be respectively provided by two (as shown in Figs. 75A to 77) or more along the lateral direction of the carrier 1. Such configuration can avoid the carrier 1 from swinging laterally on the base 400.

[00366] Next, the base operating member 420 and its related components will be described in detail.

[00367] In the base 400 according to the disclosure, the base operating member 420 is movably arranged on the base 400, and is arranged to directly or indirectly drive the base engagement member 410 to move toward the non-engaged position.

[00368] In the embodiment shown in Figs. 75A to 79, the base engagement member 410 includes a front base engagement member 410A and a rear base engagement member 410B, and the base operating member 420 may be arranged to directly drive the rear base engagement member 410B to be pivoted toward the eight rotation direction R8 as shown Fig. 77 (i.e., to move toward the non-engaged position), and simultaneously indirectly drive the front base engagement member 410A to be pivoted toward the seventh rotation direction R7 (i.e., to move toward the non-engaged position) through a base linked movement member 440. In this embodiment, the seventh rotation direction R7 of the front base engagement member 410A and the eight rotation direction R8 of the rear base engagement member 410B are opposite. However, it should be understood, the seventh rotation direction R7 of the front base engagement member 410A and the eight rotation direction R8 of the rear base engagement member 410B may be arranged to be the same, for example, the rear base engagement member 410B may be arranged to be pivoted toward the seventh rotation direction R7 to reach the non-engaged position.

[00369] The base linked movement member 440 can be a flexible member made of various materials, such as a thread, a wire, a rope and the like, or a rigid member in the form of a rod, a plate or a block. The base linked movement member 440 serves to transmit the movement of the base operating member 420 to the front base engagement member 410A.

[00370] More specifically, as shown in Figs. 76A to 81, the base operating member 420 includes: an operating member body 421, arranged to be capable of operating the base 400 from outside; an operating member extension part 422, extending from the operating member body 421 toward an interior of the base 400, so as to be able to contact and drive the base engagement member 410.

[00371] In the embodiments shown in Figs. 77, 80, 81, the operating member body 421 is provided with an operating member long slot 421 A extending along the front-rear direction of the base 400, and the base 400 is provided with a base bulged post 460 (see Fig. Fig. 81) passing through the operating member long slot 421 A, such that the base operating member 420 can move in respect with the base 400. Moreover, since the base bulged post 460 can only slide inside the operating member long slot 421 A, the position and the movement stroke of the base operating member 420 in respect with the base 400 are limited, thereby avoiding the base operating member 420 from being accidentally separated from the base 400.

[00372] Of course, the disclosure is not limited thereto. In another embodiment, as shown in Figs. 77, 80, 81, the operating member extension part 422 is provided with an operating member limiting slot 422B extending along the front-rear direction of the base 400, and the base 400 is provided with a base limiting post 491 passing through the operating member limiting slot 422B. Such configuration can also limit the movement of the base operating member 420 in respect with the base 400. This configuration can be used together with the above configuration of the operating member long slot 421 A and the base bulged post 460, or can be used alone.

[00373] In order to make the movement of the base operating member 420 in respect with the base 400 more stable, the base 400 may be provided with a U-shaped base limiting rib 492, and the operating member extension part 422 may be arranged to be able to pass through the base limiting rib 492 and move along the base limiting rib 492. Such configuration can be used together with the above configuration of the operating member long slot 421 A and the base bulged post 460 or the above configuration of the operating member limiting slot 422B and base limiting post 491, or can be used alone.

[00374] In addition, the base operating member 420 may drive the base engagement member 410 in various ways.

[00375] In the embodiment shown in Figs. 77 and 78, the operating member extension part 422 of the base operating member 420 is provided with a long operating member drive slot 422A; the base engagement member 410 is provided with an engaging member drive pin 412 (see Fig. 78), and the engaging member drive pin 412 passes through the operating member drive slot 422A. Moreover, the extending direction of the operating member drive slot 422A is inclined to the moving direction of the base operating member 420, such that when the base operating member 420 moves in respect with the base 400, the operating member drive slot 422A drives the engaging member drive pin 412 to slide therein, and the sliding direction of the engaging member drive pin 412 inside the operating member drive slot 422A will also be inclined to the moving direction of the base operating member 420, so the base engagement member 410 will be pivoted or move, thus realizing that the base engagement member 410 moves toward the non-engaged position. [00376] As shown in Fig. 77, when the base operating member 420 is operated to move, its operating member extension part 422 moves synchronously, by driving of the operating member drive slot 422A of the operating member extension part 422 to the engaging member drive pin 412 of the rear base engagement member 41 OB (see Fig. 78), the rear base engagement member 410B will be pivoted toward the eight rotation direction R8 (i.e., toward the non-engaged position). At the same time, the base linked movement member 440 connected to the operating member extension part 422 transmits the movement of the base operating member 420 to the front base engagement member 410A, and drives the front base engagement member 410A to be pivoted toward the seventh rotation direction R7 (i.e., toward the non-engaged position).

[00377] Of course, the disclosure is not limited thereto, and the base operating member 420 may drive the base engagement member 410 in other ways. For example, in an embodiment where the movement direction of the base operating member 420 is as same as the direction of the base engagement member 410 to move toward the non-engaged position, the base operating member 420 may be fixed together with or integrally formed with the base engagement member 410, thereby realizing synchronous movement. Alternatively, an intermediate member similar to the base linked movement member 440 may be arranged between the base operating member 420 and the base engagement member 410, and the Mo movement of the base operating member 420 can be transmitted to the base engagement member 410 by the intermediate member. Alternatively, the operating member extension part 422 of the base operating member 420 may enter not only to the rear base engagement member 410B, but also to the front base engagement member 410A, such that the operating member extension part 422 of the base operating member 420 can simultaneously drive the rear base engagement member 410B and the front base engagement member 410Ato be pivoted toward the same direction, thus omitting the base linked movement member 440.

[00378] In order to avoid the problem that the base operating member 420 is exposed to outside, resulting in unsightly appearance or easy damage of internal members, the base 400 further includes a bottom cover 470, as shown in Fig. 82, the bottom cover 470 is fixed to the base 400 and partially covers the base operating member 420. The bottom cover 470 partially covers the base operating member 420, which not only protects the internal members, but also enables the user to contact and operate the base operating member 420 from outside of the base 400. [00379] The base 400 according to the disclosure for placing the carrier 1 can also adopt another embodiment, which is different from the previous embodiment in that the carrier engaging member of the carrier can move between the engaged position and the non-engaged position, while the base engagement member of the base is fixed in respect with the base. Moreover, such another embodiment replaces the base operating member with a carrier operating member.

[00380] Specifically, the base 400 is provided with a base engagement member 410' (see the schematic structure shown in Figs. 75B and 76B), and the carrier 1 includes a carrier engaging member 200 (see Fig. Fig. 74). The carrier engaging member 200 is arranged on the carrier 1 to be movable between an engaged position and a non-engaged position. Among them, the carrier engaging member 200 can be engaged with the base engagement member 410' on the base 400 when in the engaged position, and the carrier engaging member 200 is disengaged from the base engagement member 410' when in the non-engaged position.

[00381] The carrier 1 further includes a carrier operating member, such as the adjusting operation member 130 shown in Fig. 74. The adjusting operation member 130 is movably arranged on the carrier 1 and is arranged to directly or indirectly drive the carrier engaging member 200 to move toward the non-engaged position. The user can drive the carrier engaging member by operating the carrier operating member on the carrier 1, thereby realizing that the carrier 1 is moved away from the base 400.

[00382] In the embodiment shown in Figs. 73 and 74, the carrier engaging member 200 of the carrier 1 can adopt the previously described connecting post 200 for connecting to the carrier application device, the carrier operating member can adopt the previously described adjusting operation member 130. In this embodiment, the base 400 can be used as a carrier application device as mentioned above, and the base engagement member 410' is a base engaging hole capable of being engaged with the connecting post 200, as shown in Figs. 75B and 76B. Specifically, the connecting post 200 is arranged on the carrier 1 to be movable between an extended position and a retracted position. The connecting post 200 can be engaged with the base engagement member 410' on the base 400 when in the extended position, such that the carrier 1 can be connected to the base 400. The connecting post 200 can be disengaged from the base engagement member 410' when in the retracted position, such that the carrier 1 can be moved away from the base 400. The adjusting operation member 130 can drive the connecting post 200 to move toward the retracted position. Thus, in the case that the carrier 1 has already been provided with a connecting post 200, it is only required to arrange the base engagement member 410' (e.g., the base engaging holes shown in Figs. 75B and 76B) which can be engaged with the connecting post 200 on the base 400, then the carrier 1 can be easily connected to or moved away from the base 400 without other components to be provided, which can greatly reduce the manufacturing and assembly costs.

[00383] In order to more stably place the carrier 1 on the base 400, the connecting post 200 of the carrier 1 can be arranged by a plurality. For example, at least two connecting posts 200 separated by a certain distance in the front-rear direction may be respectively arranged on both sides of the carrier 1, and at least two base engaging holes 410' separated by a certain distance in the front-rear direction may be respectively arranged on both side walls of the base 400, so by cooperation of the plurality of the connecting posts 200 and the plurality of the base engaging holes 410', the carrier 1 can be prevented from tipping in respect with the base 400 in the front-rear direction.

[00384] It should be understood, the connecting structure and driving of the connecting posts 200 and the adjusting operation member 130 in this embodiment may be as same as or different from those of the connecting posts 200 and the adjusting operation member 130 described above with reference to Figs. 2A, 2B, 7, 9, 23B, 25B. For example, the adjusting operation member 130 in this embodiment may be connected to and drive the connecting posts 200 through only one linked movement member 140 or another intermediate member.

[00385] Of course, the disclosure is not limited thereto. The carrier engaging member of the carrier 1 may not adopt the connecting posts200, and the carrier operating member may not adopt the adjusting operation member 130. In other embodiments, separate carrier engaging member and carrier operating member can be arranged on the carrier 1, so as to realize the engagement or disengagement of the carrier engaging member with the base engagement member 410' of the base 400, thereby placing or moving the carrier 1 to or away from the base 400.

[00386] In addition, in the case that the connecting posts 200 of the carrier 1 is only used for connecting another carrier application device but not the base 400, a side walls of the base 400 can be provided with a connecting post avoidance slot 481 at a position corresponding to the connecting post 200. As shown in Figs. 75A 76A, when the carrier 1 is placed on the base 400, the connecting post avoidance slot 481 serve to accommodate the connecting posts 200 of the carrier 1.

[00387] Figs. 83 to 91 show the second embodiment of the base 400 for placing the carrier 1 according to the disclosure, which is different from the first embodiment of the base 400 described above with reference to Figs. 73 to 82 mainly in that in the first embodiment, the base operating member 420 is constituted by a single component, and the user drives the base engagement member 410 by operating the single component for translation, while in the second embodiment, the base operating member 420 is constituted by a plurality of components, and the user drives the base engagement member 410 by operating one of the components to rotate.

[00388] Specifically, in the second embodiment of the base 400, the base operating member 420 includes an operating member rotating part 423 and an operating member driving part 424.

[00389] As shown in Figs. 84 and 86, the operating member rotating part 423 is rotatably connected to the base 400.

[00390] The operating member rotating part 423 is arranged capable of operating from outside of the base 400 to rotate it. The operating member rotating part 423 may take a form of a block, a plate, a rod or other structures specially designed.

[00391] In an embodiment, as shown in Fig. 84, the base operating member 420 may include an operating member rotating shaft 425, and the operating member rotating part 423 can rotate around the operating member rotating shaft 425.

[00392] It should be understood, the operating member rotating shaft 425 can be integrally formed with the operating member rotating part 423, or it can be a separate component independent of the operating member rotating part 423, and a shaft hole (not shown) for the operating member rotating shaft 425 to rotate therein may be formed on the base 400. Alternatively, the operating member rotating shaft 425 may be integrally formed with the base 400, and a shaft hole for the operating member rotating shaft 425 to rotate therein may be formed on the operating member rotating part 423.

[00393] In another embodiment, the base operating member 420 may not include the operating member rotating shaft 425, instead, an arc guide rail (not shown) may be formed on the base 400, and the operating member rotating part 423 may rotate along the arc guide rail.

[00394] The operating member rotating part 423 rotates on the base 400, such that the base operating member 420 does not have to extend out of the base 400 as in the first embodiment, which is beneficial to an application environment with small operation space.

[00395] The operating member driving part 424 is movably connected to the base 400, and can contact and drive the base engagement member 410. The rotation of the operating member rotating part 423 can directly or indirectly drive the operating member driving part 424 to move, thereby driving the base engagement member 410.

[00396] It should be understood, the base engagement member 410 used in the second embodiment may be as same in structure and working principle as the base engagement member 410 described in the first embodiment. Therefore, as shown in Fig. 84, the operating member driving part 424 in the second embodiment may adopt a structure similar to that of the operating member extension part 422 in the first embodiment.

[00397] For example, the operating member driving part 424 may be provided with a long driving part driving slot 424B (see Fig. 84). The driving part driving slot 424B is similar to the operating member drive slot 422A in the first embodiment, and is used for cooperating with the engaging member drive pin 412 (see Fig. 84) on the base engagement member 410, such that when the operating member driving part 424 moves in respect with the base 400, the operating member drive slot 424B drives the engaging member drive pin 412 to slide therein, and the sliding direction of the engaging member drive pin 412 inside the operating member drive slot 424B will also be inclined to the moving direction of the operating member driving part 424, so the base engagement member 410 will be pivoted or moved, thus realizing that the base engagement member 410 moves toward the non-engaged position.

[00398] For another example, the operating member driving part 424 may be provided with a driving part long slot 424C (see Fig. 84) extending along the front-rear direction of the base 400. the driving part long slot 424C is similar to the operating member long slot 421 A in the first embodiment, and is used to cooperate with the base bulged post 460 (see Figs. 80 and 81) on the base 400, such that the movement of the operating member driving part 424 in respect with the base 400 is restricted.

[00399] Hereinafter, referring to Figs. 83 to 88, an embodiment in which the rotation of the operating member rotating part 423 directly drives the operating member driving part 424 to move will be describe. In this embodiment, the operating member rotating part 423 directly acts on the operating member driving part 424.

[00400] In order to make the operating member rotating part 423 with the operating member driving part 424 be linked moving, as shown in Fig. 86, the operating member rotating part 423 is provided with a long rotating part linked movement slot 423 A, the operating member driving part 424 is provided with a long driving part linked movement slot 424A, and an operating member driving shaft 426 simultaneously passes through the rotating part linked movement slot 423 A and the driving part linked movement slot 424 A, such that the operating member rotating part 423 can drive the operating member driving part 424 to move by the operating member driving shaft 426.

[00401] More specifically, when the operating member rotating part 423 rotates under operation of the use, the rotating part linked movement slot 423 A on the operating member rotating part 423 will rotate accordingly, thus the rotating part linked movement slot 423A will bring the operating member driving shaft 426 passing therethrough to move. Since the operating member driving shaft 426 also simultaneously passes through the driving part linked movement slot 424A on the operating member driving part 424in the meantime, after the operating member driving shaft 426 in moving abuts an end of the driving part linked movement slot 424A, the operating member driving shaft 426 will bring the operating member driving part 424 to move, thus realizing that the operating member rotating part 423 drives the operating member driving part 424 to move by the operating member driving shaft 426.

[00402] As shown in Fig. 86, the carrier 1 may be provided with a driving part reset elastic member 424D. The driving part reset elastic member 424D is arranged to drive the operating member driving part 424 to move towards the initial position, such that once the user no longer acts on the operating member rotating part 423, the operating member driving part 424 will return to the initial position under the elastic force of the driving part reset elastic member 424D, and at the same time, the operating member driving part 424 will further drive the operating member rotating part 423 to return to the initial position by the operating member driving shaft 426.

[00403] The driving part reset elastic member 424D can adopt a suitable elastic member such as a spring, a torsion spring, a hydraulic rod and the like.

[00404] It should be understood, although in the embodiment shown in Fig. 86, the driving part reset elastic member 424D is arranged to directly act on the operating member driving part 424, however, in other embodiments, the driving part reset elastic member 424D may also be arranged to directly act on the operating member rotating part 423, such that the driving part reset elastic member 424D drives the operating member rotating part 423 to return to the initial position, and further, the operating member rotating part 423 drives the operating member driving part 424 to return to initial position by the operating member driving shaft 426.

[00405] In addition, the driving part reset elastic member 424D is not necessary, and the operating member rotating part 423 may be arranged to return to the initial position under operation of the user, and then the operating member driving part 424 is driven to return to the initial position by the operating member driving shaft 426.

[00406] Next, an embodiment in which the operating member rotating part 423 indirectly drives the operating member driving part 424 to move will be described with reference to Figs. 89 to 91. Different from the embodiment described above with reference to figs. 83 to 88, in this embodiment, the operating member Figs. 83 to 88, in this embodiment, the operating member rotating part 423 indirectly acts on the operating member driving part 424.

[00407] As shown in Figs. 89 and 91, the base operating member 420 further includes an operating member linked movement part 427. The operating member linked movement part 427 is arranged to transmit rotation of the operating member rotating part 423 to the operating member driving part 424, so as to drive the operating member driving part 424 to move.

[00408] Figs. 89 and 91 show an embodiment of the operating member linked movement part 427. The operating member linked movement part 427 is rotatably connected to the base 400, and is provided with a linked movement part contact end 427 A. The linked movement part contact end 427A abuts against the operating member rotating part 423, such that rotation of the operating member rotating part 423 can drive the operating member linked movement part 427 to rotate.

[00409] In order to make the operating member linked movement part 427 and the operating member driving part 424 be linked moving, the operating member linked movement part 427 is also provided with a long linked movement part long slot 427B, and a linked movement part driving shaft 428 simultaneously passes through the linked movement part long slot 427B and the driving part linked movement slot 424A, such that the operating member linked movement part 427 can drive the operating member driving part 424 to move by the linked movement part driving shaft 428.

[00410] More specifically, when the operating member rotating part 423 rotates under operation of the user, the linked movement part contact end 427A of the operating member linked movement part 427 abutting against the operating member rotating part 423 is pushed by the operating member rotating part 423 to move, such that the operating member linked movement part 427 rotates. Then, the linked movement part long slot 427B on the operating member linked movement part 427 will rotate accordingly, so, the linked movement part long slot 427B will brings the linked movement part driving shaft 428 passing therethrough to move. Since the linked movement part driving shaft 428 also simultaneously passes through the driving part linked movement slot 424A on the operating member driving part 424, when the linked movement part driving shaft 428 in moving abuts against an end of the driving part linked movement slot 424A, the linked movement part driving shaft 428 will bring the operating member driving part 424 to move, thus realizing that the movement of the operating member rotating part 423 is firstly transmitted to the operating member linked movement part 427, and then the operating member linked movement part 427 drives the operating member driving part 424 to move by the linked movement part driving shaft 428.

[00411] In order to realize the rotation of the operating member linked movement part 427, in an embodiment, as shown in Figs. 89 and 91, the operating member linked movement part 427 may include a linked movement part rotating shaft 427C, and the operating member linked movement part 427 can rotate around the linked movement part rotating shaft 427C.

[00412] It should be understood, the linked movement part rotating shaft 427C may be integrally formed with the operating member linked movement part 427, or it can be a separate component independent of the operating member linked movement part 427, and a shaft hole (not shown) for the linked movement part rotating shaft 427C to rotate therein can be formed on the base 400. Alternatively, the linked movement part rotating shaft 427C may be integrally formed with the base 400, and a shaft hole for the linked movement part rotating shaft 427C to rotate therein can be formed on the operating member linked movement part 427.

[00413] In addition, in the embodiment shown in Fig. 91, the linked movement part long slot 427B is arranged at the other end of the operating member linked movement part 427 opposite to the linked movement part contact end 427A. However, it should be understood, the linked movement part long slot 427B may be provided at other positions on the operating member linked movement part 427, as long as it can transmit the movement of the operating member rotating part 423.

[00414] Although an embodiment of the operating member linked movement part 427 has been described above with reference to Figs. 89 and 91, the disclosure is not limited thereto. The operating member linked movement part 427 may take other structures. For example, the operating member linked movement part 427 can be a flexible member such as a thread, a wire, a rope and the like, with one end connected to the operating member rotating part 423 and the other end connected to the operating member driving part 424, such that the operating member linked movement part 427 can transmit the rotation of the operating member rotating part 423 to the operating member driving part 424, so as to drive the operating member driving part 424 to move.

[00415] In the embodiment shown in Fig. 91, the carrier 1 may also be provided with a driving part reset elastic member 424. The arrangement and function of the driving part reset elastic member 424D are as same as those mentioned above, so the details are not redundantly repeated here.

[00416] As in the first embodiment, in the second embodiment of the base 400, as shown in Figs. 83 to 91, the base engagement member 410 may include a front base engagement member 410A and a rear base engagement member 410B separated by a certain distance along the front-rear direction of the base 400. Among them, the front base engagement member 410A is located at the front of the base 400, and the rear base engagement member 410B is located at the rear of the base 400. Moreover, the operating member driving part 424 may be arranged to directly drive the rear base engagement member 410B to move toward the non-engaged position, and simultaneously indirectly drive the front base engagement member 410Ato move toward the non-engaged position through a base linked movement member (not shown).

[00417] As shown in Figs. 84, 87, 88 and 89, in the case that the base engagement member 410 can be pivoted around the engaging member pivot 415 on the base 400, in order to keep the base engagement member 410 in the engaged position more stably,, the base engagement member 410 may be provided with an engaging member counterweight 414. The engaging member counterweight 414 is arranged such that the base engagement member 410 tends to be pivoted toward the engaged position. For example, the position of the engaging member counterweight 414 on the base engagement member 410 may be at a certain distance from the engaging member pivot 415 in the front-rear direction of the carrier 1, and the center of gravity of the base engagement member 410 is located between the engaging member counterweight 414 and the engaging member pivot 415 in the front- rear direction of the carrier 1, thereby facilitating the generation of a moment for the base engagement member 410 to be pivoted toward the engaged position.

[00418] In the disclosure, the engaging member counterweight 414 may adopt various suitable counterweight components such as a post, a block and the like, as long as its size and weight can be cooperative with the base engagement member 410.

[00419] Specifically, in the embodiment shown in Fig. 87, the rear base engagement member 410B is provided with a rear engaging member counterweight 414B. The rear engaging member counterweight 414B may be arranged such that the center of gravity P2 of the rear base engagement member 410B is located between the rear engaging member counterweight 414B and the rear engaging member pivot 415B in the front- rear direction of 14 the carrier 1. Thus, the center of gravity P2 of the rear base engagement member 410B will generate a moment that makes the rear base engagement member 410B be pivoted toward the engaged position.

[00420] In an embodiment, the distance X2 between the center of gravity P2 of the rear base engagement member 410B and the center line of the rear engaging member pivot 415B in the front-rear direction of the carrier 1 is equal to 4 mm.

[00421] In yet another embodiment, the center of gravity P2 of the rear base engagement member 410B may be arranged to be substantially on a horizontal plane 12 with the rear engaging member pivot 415B. For example, the rear engaging member counterweight 414B may be arranged such that the center of gravity of the rear engaging member counterweight 414B and the center line of the rear engaging member pivot 415B are on the same horizontal plane 12. In such configuration, when the vehicle is running, if an emergency situation such as an unexpected braking, or a collision caused by acceleration occurs, the center of gravity P2 of the rear base engagement member 410B will not generate a moment for the rear base engagement member 410B to be pivoted toward the non-engaged position, thereby effectively preventing the rear base engagement member 410B from being accidentally disengaged from the rear carrier engaging member 108B (see Fig. 74) of the carrier 1.

[00422] Optionally, in the embodiment shown in Fig. 88, the front base engagement member 410A is provided with a front engaging member counterweight 414A. The front engaging member counterweight 414A may be arranged such that the center of gravity Pl of the front base engagement member 410A is located between the front engaging member counterweight 414A and the front engaging member pivot 415 A in the front-rear direction of the carrier 1. Thus, the center of gravity Pl of the front base engagement member 41 OA will generate a moment for the front base engagement member 41 OA to be pivoted toward the engaged position.

[00423] In an embodiment, the distance XI between the center of gravity Pl of the front base engagement member 41 OA and the center line of the front engaging member pivot 415 A in the front-rear direction of the carrier 1 is equal to 17 mm.

[00424] In yet another embodiment, the center of gravity Pl of the front base engagement member 410A may be arranged to be substantially on the same horizontal plane II with the center line of the front engaging member pivot 415 A. For example, the front engaging member counterweight 414A may be arranged such that the center of gravity of the front engaging member counterweight 414A and the center line of the front engaging member pivot 415A are on the same horizontal plane II. In such configuration, when the vehicle is running, if an emergency situation such as an unexpected braking, or a collision caused by acceleration occurs, the center of gravity Pl of the front base engagement member 410A will not generate a moment for the front base engagement member 41 OA to be pivoted toward the non-joint position, thus effectively preventing the front base engagement member 410A from being accidentally disengaged from the front carrier engaging member 108A (see Fig. 74) of the carrier 1.

[00425] It should be understood, although in the above embodiments, the engaging member counterweight 414 is described by combining the second embodiment of the base 400, the engaging member counterweight 414 can also be applied to the first embodiment of the base 400. [00426] Carrier Application Device

[00427] Next, an embodiment of a carrier application device 500 according to the disclosure will be described with reference to Figs. 92 to 100.

[00428] It should be noted, in the disclosure, the carrier application device 500 refers to a device where the carrier 1 can be placed or applied. Although the carrier application device 500 shown in the drawings is a baby stroller, but the disclosure is not limited thereto, the carrier application device 500 according to the disclosure may also include, but is not limited to, a baby chair for carrying a baby, a child stroller for carrying a child, or cart for carrying articles or animals, or a base which can be connected to a vehicle seat and the like.

[00429] In addition, although the carrier 1 shown in the drawings is a baby basket, but the disclosure is not limited thereto, and the carrier 1 according to the disclosure can serve to carry people, animals or articles, including but not limited to a baby basket, a sleeping box, a safety seat, an animal carrying device or an article carrying device and the like.

[00430] The carrier 1 may have various embodiments, for example, the first embodiment of the carrier 1 has a pivotable anchor joint 20 (see Fig. 94), the second embodiment of the carrier 1 has a retractable anchor joint 20 (see Fig. 95), and the third embodiment of the carrier 1 does not have any anchor joint 20 (see Fig. 96).

[00431] For sake of facilitating description, a baby stroller will be taken as an example of the carrier application device 500, and a baby basket will be taken as an example of the carrier 1.

[00432] In addition, the direction for a baby in the baby stroller 500 to face is defined as front, the direction for the baby to face back is defined as back (see Figs. 92 and 94 to 96), the front-back direction is defined as the longitudinal direction of the baby stroller 500, and the left-right direction perpendicular to the front-rear direction is defined as the lateral direction T of the baby stroller 500 (see Figs. 93, 97 and 98). Other forms of the carrier application device 500 may have structures similar to or different from that of the baby stroller.

[00433] In order to safely and reliably connect the baby basket 1 to the baby stroller 500, the baby stroller 500 includes an application holding part, and the application holding part can be engaged with a carrier holding part on the baby basket 1, such that the baby basket 1 is placed on the baby stroller 500.

[00434] In the embodiment shown in Figs. 92 to 98, the application holding part includes two lateral application holding parts 510 arranged along a lateral direction T of the baby stroller 500. Correspondingly, as shown in Figs. 101 to 103, the carrier holding part of the baby basket 1 includes two lateral carrier holding parts 1G engaged with the two lateral application holding parts 510.

[00435] In order to realize engagement between the application holding part and the carrier holding part, each of the lateral application holding parts 510 is provided with a recessed part 511 (see Figs. 93, 98, 99), each of the lateral carrier holding parts 1G is provided with a bulged part 1G1 (see Figs. 101 to 103), and the recessed part 511 and the bulged part 1G1 can be engaged with each other.

[00436] In such case, since the distance between the two lateral application holding parts 510 s very close to the distance between the two lateral carrier holding parts 1G (to ensure better engagement between the lateral application holding parts 510 and the lateral carrier holding parts 1G), when the baby basket 1 is placed on the baby stroller 500, it is relatively difficult for the bulged parts 1G1 of the lateral carrier holding parts 1G to enter the recessed parts 511 of the lateral application holding parts 510.

[00437] In order to facilitate the bulged parts 1G1 to enter the recessed parts 511, in the embodiment shown in Figs. 103 and 104, the bulged parts 1G1 are arranged operable to be extended out or retracted into the baby basket 1. As shown in Fig. 103, when the bulged parts 1G1 is extended out of the baby basket 1, i.e., in the extended position, the distance between the bulged parts 1G1 on the two sides of the baby basket 1 is greater than the distance between the recessed parts 511 on the two sides of the baby stroller 500, which makes it difficult for the baby basket 1 to reach a position to be connected to the baby stroller 500. Furthermore, as shown in Fig. 104, when the bulged parts 1G1 are retracted into the baby basket 1, i.e., in the retracted position, the distance between the bulged parts 1G1 on the two sides of the baby basket 1 becomes smaller than the distance between the recessed parts 511 on the two sides of the baby stroller 500, which enables the baby basket 1 to easily reach the position to be connected to the baby stroller 500. Thus, when the user places the baby basket 1 on the baby stroller 500, he may firstly operate the bulged parts 1G1 to be retracted into the baby basket 1, such that the baby basket 1 can easily reach the position to be connected to the baby stroller 500. Then, after the bulged parts 1G1 are aligned with the recessed parts 511, the bulged parts 1G1 are operated to be extended out of the baby basket 1 and enter the recessed parts 511, thereby easily completing the engagement between the lateral application holding parts 510 and the lateral carrier holding parts IQ so as to hold the baby basket 1 in the position to be connected to the baby stroller 500.

[00438] In an embodiment, the bulged parts 1G1 capable of being extended out or retracted into the baby basket 1 may adopt the connecting posts 200 described above with reference to Figs. 6-9 and 22-25B.

[00439] Of course, the disclosure is not limited thereto.

[00440] The bulged parts 1 G1 capable of being extended out or retracted into the baby basket 1 may take other structures to realize extending and retracting of the bulged parts 1G1. For example, a button (not shown) coupled to the bulged parts 1 G1 in moving may be arranged on the baby basket 1, and the bulged parts 1G1 can be retracted into the baby basket 1 by pressing the button.

[00441] In addition, each of the lateral application holding parts 510 of the baby stroller 500 may be provided with a protuberance, and each of the lateral carrier holding parts 1G of the baby basket 1 may be provided with a recessed part. Moreover, each of the lateral application holding parts 510 of the baby stroller 500 may be provided with a protuberance which can be operated to extend out or retract into the baby stroller 500.

[00442] Furthermore, in addition to this engagement of cooperating in concave and convex, the disclosure can also adopt other engagement as cooperating in a guide rail and a guide slot.

[00443] The two lateral application holding parts 510 may be constituted by part of the baby stroller 500, or may be constituted by separate components mounted on the baby stroller 500.

[00444] In the embodiment shown in Figs. 92 to 98, the lateral application holding parts 510 are constituted by separate components mounted on the baby stroller 500. In this embodiment, each of the lateral application holding parts 510 constituted by separate components includes a holding part engaging end 512 and a holding part connecting end 513.

[00445] As shown in Fig. 99, the holding part engaging end 512 is provided with the recessed part 511 for engaging with the bulged part 1G1 arranged on the corresponding lateral carrier holding part 1G

[00446] The holding part connecting end 513 may be connected to a handbar 520 of the baby stroller 500 (see Figs. 92 to 98).

[00447] More specifically, as shown in Figs. 99 and 100, the holding part connecting end 513 is sleeve-shaped and is sleeved on the handbar 520 of the baby stroller.

[00448] In order to prevent the lateral application holding parts 510 from sliding up and down along the handbar 520, a through hole (see Fig. 99) penetrating both the handbar 520 and the holding part connecting end 513 can be formed at a connecting part between the handbar 520 and the holding part connecting end 513 and a screw or pin can be inserted in the through hole, so as to prevent the holding part connecting end 513 from moving in respect with the handbar 520.

[00449] Although the handbar 520 shown in the drawings is a lower handbar, the disclosure is not limited thereto, and the holding part connecting end 513 may be sleeved on an upper handbar of the baby stroller. In other embodiments, the holding part connecting end 513 may be connected to other parts of the baby stroller 500, such as the seat and the like.

[00450] By making the recessed parts 511 on the two sides of the baby stroller 500 and the bulged parts 1 G1 on the two sides of the baby basket 1 be engaged with each other, a two-point connection can be realized between the baby stroller 500 and the baby basket 1.

[00451] In the case of this two-point connection, the baby basket 1 can be placed forward on the baby stroller 500, that is, the facing direction of the baby in the baby basket 1 is consistent with the forward direction of the baby stroller 500, such that the visual field direction of the baby is consistent with that of the caregiver. In addition, the baby basket 1 can also be placed on the baby stroller 500 in a backward direction, that is, the facing direction of the baby in the baby basket 1 is consistent with the backward direction of the baby stroller 500 (see Figs. 94 to 96), such that the caregiver can observe the situation of the baby in the baby basket 1 more conveniently.

[00452] Of course, the disclosure is not limited thereto. In an embodiment, the application holding part may include two longitudinal application holding parts (not shown) arranged in the front-rear direction of the baby stroller 500. Correspondingly, the carrier holding part of the baby basket 1 may include two longitudinal carrier holding parts (not shown) respectively engaged with the two longitudinal application holding part.

[00453] In yet another embodiment, the application holding part may be a vertical pillar (not shown) arranged on the baby stroller 500, and the carrier holding part may be a vertical slotted hole (not shown) arranged on the baby basket 1, and by engagement between the vertical pillar and the vertical slotted hole, the baby basket 1 can be placed on the baby stroller 500.

[00454] In the case of the above two-point connection, in order to keep balance in the front-rear direction after the baby basket 1 is placed on the baby stroller 500, the two lateral carrier holding parts 1G on the baby basket 1 may be arranged in the middle part of the baby basket 1 in the front-rear direction of the baby basket 1. That is, the two lateral carrier holding parts 1G may be arranged as close as possible to the center of gravity of the baby basket 1 in the front-rear direction of the baby basket 1 , so as to reduce the tendency of the baby basket 1 to tip over along the front-rear direction.

[00455] In order to ensure that the baby basket 1 will not tip over along the front-rear direction after being placed on the baby stroller 500, the disclosure also provides the following schemes.

[00456] In a first scheme, the recessed part 511 and the bulged part 1G1 are corresponding to each other in shape and size, and are arranged such that the bulged part 1G1 cannot rotate the recessed part 511.

[00457] For example, the recessed part 511 of the application holding part may have a quadrangular opening (see Fig. 99), and the bulged part 1G1 of the carrier holding part is correspondingly a post with a quadrangular bottom (see Figs. 101 and 102). Moreover, the sizes of the recessed part 511 and the bulged part 1G1 are also corresponding to each other, i.e., the bulged part 1G1 of the carrier holding part is slightly smaller than the recessed part 511 of the application holding part in size. Thus, after the bulged part 1G1 is inserted into the recessed part 511, the bulged part 1G1 cannot rotate inside the recessed part 511, thereby preventing the baby basket 1 from tipping along the front-rear direction in respect with the baby stroller 500.

[00458] Of course, the disclosure is not limited thereto, and the recessed part 511 of the application holding part and the bulged part 1G1 of the carrier holding part may also be posts with various polygonal, elliptical or other shapes, as long as it is ensured that the bulged part 1G1 cannot rotate inside the recessed part 511.

[00459] In a second scheme, the application holding part may include a longitudinal application holding part 530, and the longitudinal application holding part 530 is spaced apart from the lateral application holding part 510 along a longitudinal direction of the baby stroller 500. Correspondingly, the carrier holding part includes a longitudinal carrier holding part 1H capable of being engaged with the longitudinal application holding part 530.

[00460] In the embodiment shown in Figs. 94 to 97, the longitudinal application holding part 530 may be an armrest of the baby stroller, and the longitudinal carrier holding part 1H can be engaged with the armrest 530.

[00461] In an embodiment, the longitudinal carrier holding part 1H is arranged to be operable to move between a connected position engaged with the longitudinal application holding part 530 and a non-connected position disengaged from the longitudinal application holding part 530. [00462] In yet another embodiment, the longitudinal carrier holding part 1H which can be operated to move between the connected position and the non-connected position may adopt the connecting hook 300 described above with reference to Figs. 12 and 26-29.

[00463] Of course, the disclosure is not limited thereto. The longitudinal application holding part 530 may adopt other components on the baby stroller 500, or alternatively, a separate component may be disposed on the baby stroller 500 as the longitudinal application holding part 530.

[00464] Similarly, the longitudinal carrier holding part 1H may adopt other components on the baby basket 1, or alternatively, a separate component may be disposed on the baby basket 1 as the longitudinal carrier holding part 1H. [00465] By engaging the recessed parts 511 on the two sides of the baby stroller 500 with the bulged parts 1G1 on the two sides of the baby basket 1, and engaging the longitudinal application holding part 530 of the baby stroller 500 with the longitudinal carrier holding part 1H of the baby basket 1, a three-point connection can be realized between the baby stroller 500 and the baby basket 1, thereby ensuring a more stable connection between the baby stroller 500 and the baby basket 1.

[00466] In the present disclosure, only one of the above first scheme and second scheme may be adopted, or both schemes may be adopted together.

[00467] As shown in Fig. 105, after the carrier 1 is placed on a carrier application device 500, a longitudinal application holding part (e.g., an armrest of the carrier 1) 530 of the carrier application device 500 is engaged with the longitudinal carrier holding part 1H of the carrier 1, so as to fix the carrier 1 in the longitudinal direction of the carrier application device 500. However, the longitudinal application holding part 530 is usually smooth (see Fig. 106), and the longitudinal application holding part 530 is not completely attached to the carrier 1, which causes it impossible for the longitudinal application holding part 530 to restrict the carrier 1 in the lateral direction of the carrier application device 500, so the carrier 1 will shake left and right in a small range, resulting in potential safety hazards or scaring the child in sleeping.

[00468] In order to avoid such situation, as shown in Fig. 107, the longitudinal application holding part 530 according to the disclosure may be provided a holding part stop structure 531, and the holding part stop structure 531 is arranged to be able prevent the carrier 1 from shaking.

[00469] In the embodiments shown in Figs. 107 to 109, the holding part stop structure 531 may be at least two stop bulges 531 arranged on the longitudinal application holding part 530. The adjacent two stop bulges 531 can clamp a part of the carrier 1 between them, such that the carrier 1 will not shake.

[00470] The stop bulges 531 may take the shape of a stereo triangle or other shapes.

[00471] In order to make the stop bulges 531 prevent the carrier 1 from shaking more effectively, in the embodiments shown in Figs. 108 and 109, the two stop bulges 531 are arranged to be non-parallel to each other. This is a preferred embodiment, but it is not limited to this, and the two stop bulges 531 may be arranged in parallel with each other.

[00472] Specifically, as shown in Fig. 108, the maximum distance Z1 between the two stop bulges 531 may be 24 mm, and the minimum distance Z2 between the two stop bulges 531 may be 19 mm.

[00473] In addition, as shown in Fig. 108, the length Z3 of each of the stop bulges 531 may be 22 mm, and the width Z4 of each of the stop bulges 531 may be 13 mm. As shown in Fig. 109, the height Z5 of each of the stop bulges 531 may be 3 mm.

[00474] Corresponding to the holding part stop structure 531 on the longitudinal application holding part 530, the carrier 1 may be provided with a carrier stop structure IK. As shown in Fig. 110, the carrier stop structure IK may be a protruding structure on the carrier 1, and its shape, size and position all corresponding to the stop bulges 531, such that the carrier stop structure IK can be engaged between the adjacent two stop bulges 531. Thus, the carrier stop structure IK is in colser contact with the stop bulges 531, such that the carrier 1 will not shake.

[00475] In one embodiment, as shown in Figs. 107 and 108, at least two stop bulges 531 are respectively provided with guide ramp 531A, and two adjacent guide ramps 531 A are oppositely arranged. The carrier stopper IK can be engaged between two adjacent guide ramps 531 A.

[00476] Of course, the disclosure is not limited thereto.

[00477] The holding part stop structure 531 and/or the carrier stop structure IK may take other structural forms.

[00478] For example, the holding part stop structure 531 may be a recess formed in the longitudinal application holding part 530, and the recess may be engaged with and in closer contact with the protruding carrier stop structure IK formed in the carrier 1.

[00479] For another example, the holding part stop structure 531 may be at least one engaging post formed in the longitudinal application holding part 530, and which may be respectively engaged with same number of the carrier stop structures IK each in a shape of an engaging hole formed in the carrier 1.

[00480] For yet another example, the holding part stop structure 531 may be a specific surface (such as curved surface, wave surface, sawtooth surface) formed on the longitudinal application holding part 530, and the specific surface may be in closer contact with the mating surface on the carrier 1 in a manner of face-to-face completely contact each other, such that the carrier 1 will not shake. In such embodiment, the carrier 1 is unnecessary to be provided a separate carrier stop structure IK.

[00481] In the above description of representative examples, directional terms (such as “up,” “down,” “left,” ’’right,” “front,” ”back“ and the like) are used for convenience of reference to the

T& drawings. However, it should be clearly understood, the scope of the disclosure is not limited to any particular direction described herein.

[00482] Since the features of the present disclosure can be embodied in various forms without departing from the characteristics of the disclosure, it should also be understood, the above embodiments are not limited to any details described above, unless otherwise specified, but should be broadly interpreted as falling within the scope defined by the appended claims, and therefore, all modifications and variations that fall within the scope and bounds of the claims or equivalents of such ranges and bounds should be covered by the appended claims.
