Specifically, as shown in fig. 1 to 3, the second locking mechanism 820 includes a second locking member 821, a second locking groove (not shown in the drawings), and a third locking groove 823, the second locking groove is provided on the first frame fixing base 600, the third locking groove 823 is provided on the second frame fixing base 700, the second locking member 821 can be simultaneously locked and engaged with the second locking groove and the third locking groove 823, and rotation of the armrest fixing base 200 can drive the second locking member 821 to disengage from one of the second locking groove and the third locking groove 823, so that the second locking mechanism 820 is converted from the locking state to the unlocking state. In this embodiment, the second locking member 821 is a gear, and the second locking groove and the third locking groove 823 are gear grooves that cooperate with the second locking member 821. Of course, in other embodiments, the second locking member 821 may have other shapes, such as an irregular polygon, and the second locking groove and the third locking groove 823 may have other corresponding shapes, respectively.

Further, as shown in fig. 3 and 4, the second locking mechanism 820 further includes a frame release lock 824 and a push-on 825. The frame release lock 824 is mounted on the first frame fixing base 600, and the frame release lock 824 may specifically include a release lock body 824a and a release lock protrusion 824b that are connected to each other, where the release lock body 824a is disposed on a surface of the first frame fixing base 600 opposite to the second frame fixing base 700, a release lock hole 613 is disposed on the first frame fixing base 600, and the release lock protrusion 824b abuts against the second lock 821 through the release lock hole 613. The pushing member 825 is fixed to the first locking member 811, for example, the pushing member 825 may be integrally formed with the first locking member 811, and the pushing member 825 may specifically include two pushing ribs 825a disposed at intervals on a surface of the first locking member 811 facing away from the seat fixing base 400. The side of the connection fixing base 500 facing away from the seat fixing base 400 is opposite to the side of the first frame fixing base 600 provided with the frame release lock 824, and the connection fixing base 500 is provided with a pushing hole 514 (as shown in fig. 6) through which the pushing piece 825 passes. The armrest fixing base 200 rotates to drive the first locking member 811 to move axially, so that the pushing member 825 can push the frame releasing member 824 through the pushing hole 514, and the releasing protrusion 824b of the frame releasing member 824 pushes the second locking member 821 to disengage from the second locking groove, so that the second locking mechanism 820 is switched from the locking state to the releasing state. Meanwhile, the pushing member 825 integrally formed with the first locking member 811 is disposed in the pushing hole 514 in a penetrating manner, so that the first locking member 811 may be limited to move only in a direction approaching or moving away from the seat fixing base 400, i.e. only in an axial direction, so as to prevent the first locking member 811 from rotating around the mounting shaft 520, thereby achieving the locking function of the first locking mechanism 810.

Further, as shown in fig. 3, 4 and 8, the second locking mechanism 820 further includes a second elastic member 826, and both ends of the second elastic member 826 respectively abut against the second locking member 821 and the second frame fixing base 700 (specifically, the sixth body portion 710), and the second elastic member 826 moves the second locking member 821 in the direction of the second locking groove (i.e., the first frame fixing base). In the present embodiment, the second elastic member 826 is a spring or an elastic rubber column sleeved on the mounting shaft 520, which is not limited. Thus, after the state transition of the infant carrier is completed, for example, when the infant carrier is converted from the folded state to the unfolded state for use, the second elastic member 826 can automatically spring the second locking member 821 back to the second locking groove, so that the first frame fixing seat 600 and the second frame fixing seat 700 can be automatically locked again, and the operation is convenient.

Further, as shown in fig. 7 to 10, the third locking mechanism 840 has a locking state and a releasing state, the backrest fixing base 300 rotates to the first position relative to the armrest fixing base 200, and the armrest fixing base 200 is locked with the seat fixing base 400 by the third locking mechanism 840; the backrest fixing base 300 rotates to the second position relative to the armrest fixing base 200, and the third locking mechanism 840 releases the locking of the armrest fixing base 200 and the seat fixing base 400.

In this embodiment, as shown in fig. 22, the second position may be a position where the backrest fixing base 300 rotates relative to the armrest fixing base 200 to the armrest supporting rod 111 and the backrest supporting rod 112 are substantially parallel or coincident; as shown in fig. 21, the first position is other than the second position. Thus, when the infant carrier needs to be folded, the backrest fixing base 300 can be rotated from the first position to the second position relative to the armrest fixing base 200, i.e. the armrest supporting rod 111 and the backrest supporting rod 112 are substantially parallel or overlapped, and at this time, the third locking mechanism 840 releases the locking of the armrest fixing base 200 and the seat fixing base 400, so that the armrest supporting rod 110, the backrest supporting rod 120 and the seat supporting rod 130 can be further operated to fold to the substantially parallel states, thereby saving the storage space of the folded seat assembly 110.

Specifically, as shown in fig. 7 to 10 and 17, the third locking mechanism 840 includes a first locking portion provided on the armrest fixing base 200 and a second locking portion provided on the seat fixing base 400, and when the back fixing base 300 rotates to the first position relative to the armrest fixing base 200, the first locking portion is in locking engagement with the second locking portion, and when the back fixing base 300 rotates to the second position relative to the armrest fixing base 200, the first locking portion is disengaged from the second locking portion. In this embodiment, the first locking portion is a locking block 841 disposed on the armrest fixing base 200, and the second locking portion is a locking groove 842 disposed on the seat fixing base 400 and capable of being matched with the locking block 841. Of course, the positions of the engaging blocks 841 and the engaging grooves 842 may be interchanged, or the third locking mechanism 840 may take other forms, such as, but not limited to, hooks and holes that cooperate with each other.

Alternatively, as shown in fig. 10 and 17, the engagement groove 842 is provided on the locking boss 411. Referring to fig. 18, the first body 210 of the armrest fixing base 200 is provided with a radially disposed mounting groove 213, the engaging block 841 is disposed in the mounting groove 213, and the engaging block 841 extends from a notch of the mounting groove 213 to be engaged with the engaging groove 842. The locking boss 411 passes through the first through hole 311 so that the locking block 841 can be locked to the locking groove 842. Alternatively, the mounting groove 213 and the mounting channel 211 are disposed along the same radial direction of the armrest fixing base 200, i.e., the engagement block 841 and the locking pin 831 are disposed along the same radial direction of the armrest fixing base 200, so that the engagement block 841 and the locking pin 831 can achieve locking of the seat fixing base 400 from both opposite sides of the armrest fixing base 200.

Further, as shown in fig. 7 to 10 and 17, the second body portion 310 of the backrest fixing base 300 has a guide rail groove 312, and the guide rail groove 312 is different from the notch of the engagement groove 842 at different positions, i.e. the extending path of the guide rail groove 312 is gradually changed. The locking block 841 has a locking portion 841a and a guide post 841b, the locking portion 841a can be inserted into the locking slot 842, the guide post 841b is inserted into the guide rail slot 312 and moves along the guide rail slot 312, when the backrest fixing base 300 rotates to the second position relative to the armrest fixing base 200, the guide rail slot 312 is farthest from the center of the second body portion 310, that is, the guide rail slot 312 is farthest from the locking boss 411, and the locking block 841 moves along the guide rail slot 312 until the locking portion 841a is separated from the locking slot 842. When the backrest fixing base 300 rotates to the first position relative to the armrest fixing base 200, the engaging block 841 moves along the rail slot 312 to the engaging portion 841a to be inserted into the engaging slot 842. Thus, on the one hand, when the backrest fixing base 300 rotates to the first position relative to the armrest fixing base 200, the third locking mechanism 840 is in a locking state, when the backrest fixing base 300 rotates to the second position relative to the armrest fixing base 200, the third locking mechanism 840 is in a releasing state, on the other hand, during the unfolding process of the infant carrier, due to the cooperation of the guide posts 841b on the clamping blocks 841 and the guide rail grooves 312, the armrest fixing base 200 and the backrest fixing base 300 form linkage during pivoting, so that the armrest supporting rod 111 can be unfolded together with the backrest supporting rod 112 and even the whole infant carrier, and can be automatically returned to the initial position, thereby realizing the automatic return of the armrest supporting rod 111 during the unfolding process. Thus, during the folding process of the infant carrier, the backrest fixing base 300 can drive the armrest fixing base 200 to rotate relative to the seat fixing base 400 in the original direction until the folding process is completed.

Further, as shown in fig. 8, 10 and 28, the third locking mechanism 840 further includes a third elastic member 843, two ends of the third elastic member 843 respectively abut against the armrest fixing base 200 and the engagement block 841, specifically, two ends of the third elastic member 843 respectively abut against the engagement block 841 and the groove bottom of the mounting groove 213, and the third elastic member 843 moves the engagement block 841 in a direction toward the engagement groove 842. Thus, after the state transition of the infant carrier is completed, for example, the state transition from the folded state to the unfolded state, the backrest fixing base 300 rotates to the first position relative to the armrest fixing base 200, and the locking block 841 can be automatically locked into the locking groove 842 under the action of the third elastic member 843, so as to lock the armrest fixing base 200 and the seat fixing base 400, thereby improving the safety performance.

Specifically, as shown in fig. 28, the third elastic member 843 may be mounted by providing a mounting table 841c on the engaging block 841, where the mounting table 841c includes an abutting portion 841d and a protruding portion 841e that are connected to each other, the third elastic member 843 is partially sleeved outside the protruding portion 841e, and an end of the third elastic member 843 away from the bottom of the mounting groove 213 abuts against the abutting portion 841 d. Of course, other means of mounting the third elastic member 843 may be employed. The third elastic member 843 may be a spring, an elastic rubber column, or the like, which is not limited thereto.

Further, as shown in fig. 7 to 10, the fourth locking mechanism 830 can achieve the relative locking of the armrest fixing base 200 and the seat fixing base 400, and when the backrest fixing base 300 rotates to the second position relative to the armrest fixing base 200, the fourth locking mechanism 830 can be operated so that the armrest fixing base 200 rotates relative to the seat fixing base 400. Thus, when the fourth locking mechanism 830 is operated, the armrest fixing seat 200 and the seat fixing seat 400 are unlocked, the armrest fixing seat 200 and the seat fixing seat 400 rotate relatively, and finally the armrest supporting rod 111, the seat supporting rod 113 and the backrest supporting rod 112 are in a nearly parallel state, and the armrest supporting rod 111 is not inclined or protrudes outwards, so that the overall volume is smaller after folding, the transportation cost is reduced, and the storage and the placement are convenient. Because of the smart cooperation of the fourth locking mechanism 830 and the third locking mechanism 840, a dual locking safety effect is provided for the infant carrier, if the fourth locking mechanism 830 is operated alone or the backrest fixing base 300 is rotated to the second position relative to the armrest fixing base 200 so that the third locking mechanism 840 is in the unlocking state, the unlocking of the infant carrier cannot be achieved, and only if the fourth locking mechanism 830 and the third locking mechanism 840 are simultaneously unlocked, the armrest supporting rod 111, the backrest supporting rod 112, the seat supporting rod 113 and the like of the infant carrier can be rotated relatively. This can prevent the infant carrier from being accidentally folded when the fourth locking mechanism 830 is touched by mistake or rotates the backrest support bar 112 to be substantially parallel or coincident with the armrest support bar 111, thereby greatly improving the safety performance of the infant carrier.

Specifically, as shown in fig. 7 to 10, the fourth locking mechanism 830 includes a third locking portion provided on the armrest fixing base 200 and a fourth locking portion provided on the seat fixing base 400, the third locking portion being operable to be locked or unlocked in cooperation with the fourth locking portion, or the fourth locking portion being operable to be locked or unlocked in cooperation with the third locking portion.

Alternatively, as shown in fig. 7 to 10 and 17, the third locking portion is a locking pin 831 movably disposed on the armrest fixing base 200, and the fourth locking portion is a fourth locking groove 832 disposed on the seat fixing base 400 and capable of being engaged with the locking pin 831. Thus, the armrest fixing base 200 and the seat fixing base 400 can be locked by the engagement of the locking pin 831 and the fourth locking groove 832, and the fourth locking mechanism 830 can be unlocked by operating the locking pin 831 such that the locking pin 831 is disengaged from the fourth locking groove 832, and the armrest fixing base 200 and the seat fixing base 400 can be rotated relative to each other, that is, the armrest support rod 111 and the seat support rod 113 can be rotated relative to each other. Of course, the positions of the locking pins 831 and the fourth locking grooves 832 may be interchanged, or the third locking portion and the fourth locking portion may be other forms, such as hooks and holes, etc., which can be engaged with each other, without limitation.

Further, as shown in fig. 17, a fourth locking groove 832 is provided on the locking boss 411. Referring to fig. 18, a mounting channel 211 may be formed on the first body 210 of the armrest fixing base 200, and one end of the locking pin 831 may pass through the mounting channel 211 to cooperate with the fourth locking slot 832, and the other end of the locking pin 831 may protrude out of the mounting channel 211 to be operated. The locking boss 411 passes through the first through-hole 311 so that the locked pin 831 can be locked-engaged with the fourth locking groove 832.

Further, as shown in fig. 10 and 13, the fourth locking mechanism 830 further includes a fourth elastic member 833, two ends of the fourth elastic member 833 respectively abut against the armrest fixing seat 200 and the locking pin 831, and the fourth elastic member 833 makes the locking pin 831 constantly move toward the fourth locking slot 832. Thus, after the state transition of the infant carrier is completed, for example, the infant carrier is converted from the folded state to the unfolded state, the locking pins 831 can be automatically locked into the fourth locking grooves 832 under the action of the fourth elastic members 833 to realize the re-locking of the armrest fixing seat 200 and the seat fixing seat 400, so that the locking pins 831 do not need to be further manually operated, time and labor are saved, and the safety performance can be improved.

Alternatively, as shown in fig. 10 and 13, the fourth elastic member 833 may be disposed in such a manner that a limiting post (not shown in the drawings) is disposed on an inner wall of the mounting channel 211, a radially disposed limiting hole 831a is disposed on the locking pin 831, the limiting post is inserted into the limiting hole 831a, and two ends of the fourth elastic member 833 respectively abut against the limiting post and a hole wall of a side of the limiting hole 831a away from the locking boss 411. Thus, the fourth elastic member 833 can function to assist the resetting of the locking pin 831. Of course, the fourth elastic member 833 may be provided in other manners. The fourth elastic member 833 is a spring, an elastic rubber column, or the like, and is not limited thereto.

Further, as shown in fig. 11, the fourth locking mechanism 830 further includes an operating member 834 connected to the locking pin 831, where the operating member 834 can be operated to activate the locking pin 831. Thus, the locking pin 831 can be conveniently operated by the user, and the user experience is improved. Alternatively, the operating member 834 is a webbing, and the webbing is employed as the operating member 834 occupies little storage space and also little increases the overall weight of the infant carrier. Of course, the operating member 834 may be a tab or the like, which is not limited thereto. The locking pin 831 may be provided with a penetrating hole 831b at an end protruding from the mounting channel 211, and the webbing may be wound around and fixed to the locking pin 831 through the penetrating hole 831b, however, the webbing may be fixed to the fixing pin in other manners, which is not limited.

Further, as shown in fig. 7 and 9, the fifth locking mechanism 850 has a locked state and an unlocked state, in this embodiment, the fifth locking mechanism 850 includes a back release lock 851 located on top of the back support bar 112, and by pressing the back release lock 851, the fifth locking mechanism 850 can be switched from the locked state to the unlocked state, thereby achieving the angular adjustment of the back support bar 112 relative to the armrest support bar 111. The fifth locking mechanism 850 is in a locked state, the backrest fixing base 300 is locked relative to the armrest fixing base 200, the fifth locking mechanism 850 is in a released state, and the backrest fixing base 300 rotates relative to the armrest fixing base 200.

The following is a specific process for converting the infant carrier from the unfolded state to the folded state:

as shown in fig. 21 to 23, the backrest locking member 851 is pressed first, so that the fifth locking mechanism 850 is released, the backrest fixing base 300 can rotate to the second position (as shown in fig. 22) relative to the armrest fixing base 200, the backrest support rod 112 coincides with or is parallel to the armrest support rod 111, and the backrest support rod 112 is blocked by the armrest support rod 111 from continuing to rotate forward. At the same time, the third locking mechanism 840 releases the lock, and the engagement block 841 is disengaged from the engagement groove 842. At this time, the webbing is pulled to disengage the locking pin 831 from the fourth locking groove 832, and the fourth locking mechanism 830 is released, so that the armrest fixing base 200 and the seat fixing base 400 can rotate relatively to respectively drive the armrest support rod 111 and the seat support rod 113 to rotate in a direction approaching the backrest support rod 112, and finally the armrest support rod 111, the seat support rod 113 and the backrest support rod 112 are in a nearly parallel state, and the armrest support rod 111 does not incline or protrude outwards. Meanwhile, when the armrest fixing base 200 rotates, the driving piece 813 can push the first locking piece 811, so that the first locking piece 811 is separated from the first locking groove 812, i.e. the first locking mechanism 810 releases the lock, and the seat fixing base 400 and the connection fixing base 500 can rotate relative to each other, i.e. the seat support bar 113 can rotate and fold relative to the frame assembly 120. When the first locking member 811 is pushed, the pushing member 825 of the first locking member 811 pushes the frame release locking member 824 of the second locking mechanism 820, so as to release the locking between the rider support rod 121 and the front foot support rod 122, and drive the rider support rod 121 and the front foot support rod 122 to rotate and fold together. Thus, the whole infant carrier can be folded (as shown in fig. 23).

The infant carrier has at least the following technical effects:

in the infant carrier, the armrest fixing base 200, the seat fixing base 400 and the connection fixing base 500 are coaxially pivoted, and the armrest fixing base 200 and the seat fixing base 400 are fixed to the frame assembly 120 through the connection fixing base 500, i.e., when the armrest support rod 111 and the seat support rod 113 are respectively connected with the armrest fixing base 200 and the seat fixing base 400, the armrest support rod 111 and the seat support rod 113 are fixed to the frame assembly 120. The first locking mechanism 810 can be used to control the relative fixation and relative rotation between the seat mount 400 and the connection mount 500, i.e., between the seat support bar 113 and the frame assembly 120. When the infant carrier needs to be folded, the armrest fixing base 200 is rotated to convert the first locking mechanism 810 from the locking state to the unlocking state, i.e. the locking between the seat support rod 113 and the frame assembly 120 is released, the seat support rod 113 can be rotated to fold, i.e. the whole infant carrier is driven to fold, so that the whole size of the folded infant carrier is smaller. By adopting the mode of rotating the armrest fixing seat 200 (namely rotating the armrest supporting rod 111) to link and fold the seat assembly 110, compared with the traditional mode of linking and folding the seat supporting rod 113 through the backrest supporting rod 112, the manufacturing process can be well controlled, the use is convenient, the situation that the seat supporting rod 113 is unlocked by directly folding the backrest supporting rod 112 can be avoided, and the safety coefficient is higher.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The foregoing examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
