Fig. 1 is a schematic exploded view of some embodiments of the disclosed child carrier. Fig. 2 is a schematic structural view of some embodiments of the child carrier of the present disclosure in a first state. Fig. 3 is a schematic structural view of some embodiments of the child carrier of the present disclosure in a second state.

Referring to fig. 1-3, embodiments of the present disclosure provide a child carrier including a basket and a collapsible bracket structure. The collapsible bracket structure is detachably connected with the basket body 10 of the basket. Referring to fig. 1, the basket may include a basket body 10 and a handle assembly 20 rotatably disposed on the basket body 10. The basket provides space for children or infants to sit on and can be transferred and carried by the carrying handle assembly.

The foldable stand structure can be folded to reduce the storage size, thereby making the child carrier easier to store or carry. The foldable support is detachably connected with the basket body, so that a user can split the basket and the foldable support structure to conveniently carry, fold or change the using mode of the child carrier. The replacement of either the basket or the collapsible bracket structure may also be accomplished as desired.

Referring to fig. 1, in some embodiments, the collapsible bracket structure comprises: a rear joint assembly 61, a forefoot assembly 62, a link assembly 63, a rearfoot assembly 64, and a chute assembly 65. In other embodiments, the collapsible bracket structure may take other forms, including other structural members.

In fig. 2, a rear joint assembly 61 is provided on the basket body 10, one end of a front foot assembly 62 far from the ground is rotatably connected with the basket body 10, one end of a link assembly 63 is connected with the front foot assembly 62, the other end of the link assembly 63 is connected with the rear joint assembly 61, a rear foot assembly 64 is connected with the rear joint assembly 61, and is rotatable relative to the link assembly 63, a chute assembly 65 is provided on the basket body 10, and the rear joint assembly 61 is slidably connected with the chute assembly 65 to switch the child carrier between a first state S1 and a second state S2.

Referring to the first state shown in fig. 2, in the first state S1, the rear joint assembly 61 is located at an end of the chute assembly 65 remote from the ground, and the front foot assembly 62 is abutted against the lower portion 11 of the basket body 10, and the rear foot assembly 64 is abutted against the back portion 12 of the basket body 10.

To reach the first state S1 from the second state S2, the forefoot assembly 62 can be rotated back to a position against the lower part 11 of the basket body 10, at which point the cross beam on the forefoot assembly 62 can be inserted into the notch 14 of the lower part 11 of the basket body 10 and can be locked by means of a locking element. With the rearward rotation of the forefoot assembly 62, the connecting rod assembly 62 is driven to push the joint assembly 61 to move upwards under the guiding action of the chute assembly 65, and the rear foot assembly 64 swings forwards while moving upwards along with the upward movement of the joint assembly 61 through the cooperation of the structure in the joint assembly 61 and the two non-parallel chutes 651, 652 of the chute assembly 65, so as to be abutted against the back 12 of the basket body 10.

At this time, the child carrier has been folded to a size similar to that of the basket itself, and is conveniently used as the basket, or put into a car to be used as a child safety seat. The handle assembly 20 is adjustable to a suitable rotational position as desired.

Referring to the second state S2 shown in fig. 3, in the second state S2, the rear joint assembly 61 is located at an end of the chute assembly 65 near the ground, and the forefoot assembly 62 and the rearfoot assembly 64 are supported on the ground by a wheelset.

To pass from the first state S1 to the second state S2, the forefoot assembly 62 may be rotated forward to a position where it is supported on the ground by the wheelsets. With the forward rotation of the forefoot component 62, the connecting rod component 62 is driven to pull the joint component 61 to move downwards under the guiding action of the chute component 65, and the heel component 64 swings backwards while moving downwards along with the downward movement of the joint component 61 due to the cooperation of the structure in the joint component 61 and two non-parallel chutes of the chute component 65, so that the position supported on the ground through the wheel set is reached, and at the moment, the joint component 61 can be locked at the bottom end of the chute component 65 through the locking piece.

At this point the child carrier has been deployed into a child stroller, and the handle assembly 20 can be adjusted to a suitable rotational position as desired for pushing the push rod of the child stroller to move over the ground.

In view of the complexity of the folding and unfolding of the collapsible bracket structure relative to the basket, and the corresponding adjustment of the handle assembly, embodiments of the present disclosure further provide a basket that may be used with the collapsible bracket structure or as part of a product, or may be used separately or as a separate product and the collapsible bracket structure separately, in order to reduce the safety risk associated with user mishandling or unfamiliar with handling.

Fig. 4 is a structural exploded schematic view of some embodiments of the basket of the present disclosure. The basket includes: the handle assembly 20 is connected to the handle body 10. A handle assembly 20 is rotatably disposed on the basket body 10. The handle assembly 20 includes a handle upper tube 21, a handle lower tube 22, and a swivel joint 23. The handle upper tube 21 is inserted into the handle lower tube 22 and is telescopic relative to the handle lower tube 22, and the rotary joint 23 is connected with the handle lower tube 22 and is rotatably connected with the basket body 10.

The first lock-unlock mechanism includes a first lock 31 and a first unlock 32, the first lock 31 being configured to lock at least two telescopic positions of the handle upper tube 21 relative to the handle lower tube 22, respectively, and the first unlock 32 being configured to disengage the first lock 31 from a lock position upon receiving an operation force.

The handle upper tube 21 may be locked in a longer extended position relative to the handle lower tube 22 to accommodate, for example, pushing or the like, or may be locked in a shorter extended position relative to the handle lower tube 22 to accommodate, for example, lifting or reducing the space occupied by the handle assembly.

The safety mechanism is configured to unlock the rotational lock of the revolute joint 23 with respect to the basket body 10 when the first locking member 31 locks the first telescopic position of the handle upper tube 21 with respect to the handle lower tube 22, and to lock the rotational position of the revolute joint 23 with respect to the basket body 10 when the first locking member 31 does not lock the first telescopic position of the handle upper tube 21 with respect to the handle lower tube 22.

The lifting handle assembly which can stretch and retract and can rotate relative to the lifting basket body is adopted, and locking and unlocking of at least two stretching positions of the lifting handle upper pipe and the lifting handle lower pipe of the lifting handle assembly are achieved through the first locking and unlocking mechanism. If the first locking piece locks the upper handle tube and the lower handle tube at the first telescopic position of the upper handle tube and the lower handle tube, the safety mechanism unlocks the rotating joint and the rotation locking of the lifting basket body, and if the upper handle tube and the lower handle tube are not locked at the first telescopic position, the safety mechanism locks the rotating joint and the rotation position of the lifting basket body so that the rotating joint and the lifting basket body cannot rotate relatively, thus the rotation of the lifting handle assembly relative to the lifting basket body can be realized after the condition that the upper handle tube and the lower handle tube are at the first telescopic position is necessarily met, and the safety risks such as tipping of the lifting basket caused by the fact that an operator touches the first unlocking piece by mistake or is not familiar with the operation of the first unlocking piece and applies a moment for rotating the lifting handle assembly are avoided.

Referring to fig. 4, in some embodiments, the basket further includes a second locking and unlocking mechanism. The second locking and unlocking mechanism includes a second locking piece 51 configured to lock the rotational position of the rotational joint 23 with respect to the basket body 10, and a second unlocking piece 52 configured to disengage the second locking piece 51 from the locking position upon receiving an operation force.

In fig. 4, the second locking piece 51 may be formed to have a profile structure with a plurality of tooth shapes, capable of locking engagement with the inner tooth structure provided on the joint engagement portion 13 on the rotation joint 23 and the basket body 10, and when the second locking piece 51 is in locking engagement with both the inner tooth structure of the rotation joint 23 and the inner tooth structure of the joint engagement portion 13, the rotation joint 23 is locked against rotation with respect to the basket body 10.

For the user, the second unlocking member 52 is operated to disengage the second locking member 51 from the locking position, for example, the second unlocking member 52 is pressed down, so that the second unlocking member 52 moves the second locking member 51 inward by pressing the second locking member 51 by the boss, and moves out of the position of locking engagement with the rotary joint 23, thereby releasing the rotary locking action of the second locking member 51 on the rotary joint 23. Thus, with the safety mechanism releasing the rotational lock between the rotational joint 23 and the basket body 10, the handle assembly 20 can be rotated to the proper working position relative to the basket body 10 by operating the second unlocking member 52.

On the other hand, the handle assembly 20 cannot be rotated relative to the basket body 10 either by operating the second unlocking member in a state in which the safety mechanism locks the rotational position of the rotational joint relative to the basket body 10 or by unlocking the rotational lock of the rotational joint 23 and the basket body 10 by the safety mechanism in a state in which the second unlocking member is not operated, so that the risk of a user due to a wrong operation is effectively reduced.

FIG. 5 is a schematic view of the angle of the handle assembly relative to the basket body in some embodiments of the basket of the present disclosure. Referring to fig. 5, in some embodiments, the safety mechanism is configured to unlock the rotational position of the revolute joint 23 relative to the basket body 10 and lock the handle upper tube 21, the handle lower tube 22, and the revolute joint 23 in the first telescopic position when the angle α formed by the plane of the handle assembly 20 relative to the forward direction F of the basket body 10 is greater than a preset angle threshold.

The preset angle threshold may be used to determine a suitable value or range of values, such as 45 ° or 60 °, for example, with reference to a ride height that is more comfortable or more effort-saving by the user when pushing the stroller. When the included angle α is greater than the predetermined angle threshold, which generally corresponds to the use of the carrier in the non-push mode, the handle assembly 20 may be rotated to a suitable position as desired, such as to an angular position perpendicular to the forward direction F when used as a carrier or to an angular position greater than 90 when used as a child safety seat, etc. At this time, the upper handle tube 21, the lower handle tube 22 and the rotary joint 23 are locked by the safety mechanism, so as to prevent the upper handle tube 21 from suddenly extending under the lifting effect to cause the risks of injury or frightening of children.

Fig. 6 is an exploded view of the handle down tube, swivel joint, safety mechanism, and second locking and unlocking mechanism of some embodiments of the basket of the present disclosure. Referring to fig. 6, in some embodiments, the first telescoping position is the telescoping position of the at least two telescoping positions that is closest to the revolute joint 23. This first telescopic position may be relatively close to the swivel joint 23, thus locking the handle upper tube 21 in a relatively short or shortest position relative to said handle lower tube 22, so that the handle assembly can be adjusted to a shorter state.

In fig. 6, the handle lower pipe 22 may have a first card slot 221 and a second card slot 222, and the second card slot 222 is located at a lower side of the first card slot 221. The first locking member 31 is disposed at the bottom end of the handle upper tube 21, and can be locked into the first locking groove 221 or the second locking groove 222 under the elastic force of the first elastic member 33. In a state where the first locking member 31 is engaged with the first engagement groove 221, the handle upper tube 21 is extended and locked with respect to the handle lower tube 22, and when the first locking member 31 is engaged with the second engagement groove 222, the first locking member 31 locks the handle upper tube 21 in the first expansion position with respect to the handle lower tube 22.

FIG. 7 is an exploded schematic view of the handle top tube, handle bottom tube, and first locking and unlocking mechanism of some embodiments of the basket of the present disclosure. Fig. 8 is a schematic view of an assembled structure of a handle top tube and a first unlocking member in some embodiments of the basket of the present disclosure. Referring to fig. 7 and 8, in some embodiments, the first unlocking member 32 includes: a first lock release operating assembly 321 and a pull cord 322. The first lock release operating assembly 321 is located on the handle upper tube 21. The pull cord 322 is disposed in the inner cavity of the upper handle tube 21, and has one end connected to the first lock release operating assembly 321 and the other end connected to the first locking member 31. The first lock release operating assembly 321 is configured to pull the first locking member 31 through the pulling cord 322 when receiving an operating force, so that the first locking member 31 is disengaged from the first or second locking groove 221 or 222 against an elastic force.

The pull cord 322 may be a wire rope or other flexible cord that provides tension. The first lock release operating member 321 may take the form of a button. In fig. 7 and 8, a first unlocking operation member 321 may be provided at an upper portion of the handle upper tube (i.e., a cross member that can be used for pushing). In cooperation with the first unlocking operation assembly 321, the first unlocking piece 32 may further include: an upper cover 323, a lower cover 325, and a pulling member 324. The cross member of the handle upper tube 21 may be provided with a through groove so that the upper cover 323 and the lower cover 325 surround the handle upper tube 21 and pass through the groove to be fastened to each other. The pulling member 324 may be provided in the cross beam and slide on a surface of the lower cover 323.

The pulling member 324 may be provided in two pieces to be engaged with the first unlocking operation member 321. The first unlocking operation assembly 321 is installed in the through hole of the upper cover 323, and has two first wedge portions 3211 which can be respectively engaged with the second wedge portions 3241 of the two pulling pieces 324 through wedge surfaces, so that the two pulling pieces 324 are slid toward each other when the first unlocking operation assembly 321 is pressed. The end portions of the pull ropes 322 at the two sides are connected with the two pulling members 324, so that the two pulling members 324 slide towards each other to drive the first locking members 31 at the two sides to overcome the elastic force of the elastic member 33 and separate from the first clamping groove 221 or the second clamping groove 222.

Fig. 9 is a schematic structural view of a joint engagement portion in some embodiments of the basket of the present disclosure. FIG. 10 is a schematic cross-sectional view of the handle upper tube in some embodiments of the basket of the present disclosure in position relative to the rotational joint when the handle lower tube is not in the first telescoping position. FIG. 11 is a schematic cross-sectional view of some embodiments of the basket of the present disclosure in which the handle upper tube is locked in a first telescoping position relative to the handle lower tube and the safety mechanism releases the rotational lock of the rotational joint to the basket body.

Referring to fig. 6 to 11, in some embodiments, the handle upper tube 21 has a third clamping groove 211, the handle lower tube 22 has a fourth clamping groove 223, the rotational joint 23 has a fifth clamping groove 231, and the third clamping groove 211, the fourth clamping groove 223, and the fifth clamping groove 231 are at least partially aligned in a state that the first locking member 31 is clamped into the second clamping groove 222. The safety mechanism comprises a blocking piece 41, a limiting elastic piece 42 and a safety limiting piece 43. The safety stopper 43 has a telescopic stopper 431, and the blocking piece 41 is disposed between the pivot joint 23 and the handle lower tube 22.

In fig. 6 and 10, the blocking piece 41 is held at a position blocking the fourth clamping groove 223 by the limiting elastic piece 42, so as to limit the telescopic limiting piece to be clamped into the fourth clamping groove 223 through the fifth clamping groove 231. The blocking piece 41 is held in a position to block the fourth catching groove 223 when the handle upper tube 21 is not retracted downward to the first telescopic position, so that the telescopic stopper cannot enter the fourth catching groove 223. Thus, the interference effect of the safety mechanism on the extension and retraction of the handle assembly can be avoided.

In fig. 11, when the first locking member 31 is locked in the second locking groove 222, the handle upper tube 21 may abut against the blocking block 41, so that the blocking block 41 may be separated from the position blocking the fourth locking groove 223, and the expansion and contraction limiting portion 431 may be locked in the fourth locking groove 223 and the third locking groove 211 via the fifth locking groove 231. In this way, the first locking member 31 can be locked in a telescopic manner by the telescopic limiting portion 431, so that the risk of extension of the handle assembly is not caused even if the user mismanipulates the first unlocking member 32 in a situation where telescopic is not desired (for example, the included angle α is greater than the preset angle threshold).

Referring to fig. 6, 10 and 11, in some embodiments, the safety stop 43 is hinged within the rotational joint 23, and the safety mechanism further includes a safety spring 44, the safety spring 44 being configured to cause the expansion stop 431 to tend to snap into the fourth detent 223. In fig. 6 and 11, the locking protection sleeve 35 is fixedly provided at the lower end of the telescopic upper tube 21 by the locking pin 36, and the pressing stopper 41 moves toward the rotation joint 23 when it is retracted to the deepest position of the telescopic lower tube 22 with the telescopic upper tube 21, thereby yielding the fourth locking groove 223. The safety stopper 43 automatically engages the expansion and contraction stopper 431 into the fourth engaging groove 223 under the elastic force of the safety elastic member 44.

FIG. 12 is a schematic cross-sectional view of some embodiments of the basket of the present disclosure in which the handle upper tube is locked in a first telescoping position relative to the handle lower tube and the safety mechanism locks the rotational joint to rotation of the basket body. FIG. 13 is another cross-sectional schematic view of some embodiments of the basket of the present disclosure in which the handle upper tube is locked in a first telescoping position relative to the handle lower tube and the securing mechanism locks the rotational joint to rotation of the basket body.

Referring to fig. 6 and 9-13, in some embodiments, the basket body 10 has a joint engaging portion 13, the rotary joint 23 is sleeved on the joint engaging portion 13, the joint engaging portion 13 has a rotation limiting groove 131, the safety limiting member 43 has a telescopic limiting portion 431 and a rotation limiting portion 432, and the safety mechanism further includes a safety elastic member 44, and the safety elastic member 44 is configured such that the telescopic limiting portion 431 tends to be snapped into the fourth clipping groove 223.

When the included angle α formed by the plane of the handle assembly 20 relative to the forward direction of the basket body 10 is a preset angle threshold, and the first locking member 31 is not locked in the second locking groove 222, the safety mechanism can make the expansion limiting portion 431 blocked by the blocking block 41 and not locked in the fifth locking groove 231, the third locking groove 211 and the fourth locking groove 223, and make the rotation limiting portion 432 locked in the rotation limiting groove 131, so as to realize rotation locking of the rotation joint 23 and the joint matching portion 13.

When the included angle α is a preset angle threshold, the handle assembly 20 of the lifting basket is at the pushing position, and at this time, if the handle assembly 20 rotates when not locked at the first telescopic position, a safety risk is brought, so that the safety mechanism does not clamp into the fifth clamping groove 231, the third clamping groove 211 and the fourth clamping groove 223 by limiting the telescopic limiting portion 431, and then the rotation limiting portion 432 located at the other end of the pivot on the safety limiting member 43 clamps into the rotation limiting groove 131, so that the rotation joint 23 and the joint mating portion 13 cannot rotate relative to each other.

When the included angle α formed by the plane of the handle assembly 20 relative to the forward direction of the basket body 10 is a preset angle threshold, and the first locking member 31 is locked into the second locking groove 222, the safety mechanism may further enable the telescopic limiting portion 431 to be locked into the fifth locking groove 231, the third locking groove 211 and the fourth locking groove 223 during rotation of the handle assembly 20, and enable the rotation limiting portion 432 to be disengaged from the rotation limiting groove 131, so as to release the rotation locking of the rotation joint 23 and the joint matching portion 13.

When the included angle alpha is a preset angle threshold, the handle assembly 20 of the basket is in the pushing position, and at this time, if the handle assembly 20 is locked in the first telescopic position, the handle assembly is ready to be switched from the pushing state to other working states by rotating the handle assembly. Therefore, the safety mechanism releases the restriction that the telescopic limiting portion 431 is locked in the fifth locking groove 231, the third locking groove 211 and the fourth locking groove 223, and accordingly, the rotation limiting portion 432 of the safety limiting member 43 located at the other end of the pivot shaft is separated from the rotation limiting groove 131 along with the locking of the telescopic limiting portion 431, so that the rotation of the rotation joint 23 relative to the joint matching portion 13 is not limited any more. Thus, the handle component can rotate relative to the basket body after the second unlocking piece is pressed in a matched mode.

Referring to fig. 6 and 9-13, in some embodiments, the basket body 10 has a joint engaging portion 13, the revolute joint 23 is sleeved on the joint engaging portion 13, the joint engaging portion 13 has a rotation guiding groove 132, and the safety stopper 43 has a telescopic stopper 431 and a rotation stopper 432.

When the included angle α formed by the plane of the handle assembly 20 relative to the forward direction of the basket body 10 is greater than the preset angle threshold, and the first locking member 31 is locked into the second locking groove 222, the safety mechanism can make the rotation limiting portion 432 be locked into the rotation guiding groove 132, so that the rotation limiting portion 432 rotates within the limited rotation range of the rotation guiding groove 132, and make the expansion limiting portion 431 be locked into the fifth locking groove 231, the third locking groove 211 and the fourth locking groove 223, so as to limit expansion of the handle upper tube 21 relative to the handle lower tube 22.

When the included angle α is greater than the preset angle threshold, the handle assembly 20 is in the non-pushing position, and the handle assembly 20 can adjust the rotation angle as required, so that the extension brings about a safety risk. Therefore, the safety mechanism makes the rotation limiting portion 432 be locked into the rotation guiding groove 132, and the rotation guiding groove 132 has a certain angle range along the circumferential direction, so that the rotation limiting portion 432 can slide within the angle range of the rotation guiding groove 132. The rotation guide groove 132 may be shallower than the rotation limit groove 131, so that the expansion and contraction limit portion 431 does not separate from the fifth engagement groove 231, the third engagement groove 211, and the fourth engagement groove 223 when the rotation limit portion 432 is engaged with the rotation guide groove 132. In this way, the expansion and contraction limiting portion 431 is engaged with the fifth engagement groove 231, the third engagement groove 211, and the fourth engagement groove 223, thereby limiting expansion and contraction of the handle upper tube 21 with respect to the handle lower tube 22.
