[0082] Further, the seat pocket assembly 300 and the structural member 100 are detachably installed and fixed to the frame assembly 200; the second installation structure on the seat pocket assembly 300 for assembling with the frame assembly 200 is the same as the first installation structure on the structural member 100 for assembling with the frame assembly 200. In this way, the seat pocket assembly 300 and the structural member 100 can share the installation matching structure 210.

[0083] Continuing to refer to Figure 10 As shown in the figure, in addition to comprising the installation matching structure 210, the frame assembly 200 further comprises a support frame 220, a handle structure 230 and a wheel 240, the installation matching structure 210 is installed on the support frame 220, the wheel 240 is installed at the bottom of the support frame 220, and the handle structure 230 is installed at the top of the support frame 220 and is used for being held and pushed by the user. In some embodiments, the installation matching structure 210 is installed at the top of the support frame 220.

[0084] The support frame 220 comprises a pair of side frame bodies and a transverse frame body connected between the pair of side frame bodies, the transverse frame body is provided with the installation matching structure 210 for installing and fixing the base 110, the installation matching structure 210 has the first connecting structure and the second connecting structure which are oppositely arranged in the front-back direction, the base 110 is provided with the second lock groove matched with the first connecting structure and the locking piece 113 matched with the second connecting structure. In an embodiment, the first connecting structure is a lock tongue; and the second connecting structure is a first lock groove.

[0085] AsFigure 1 and Figure 13 As shown in FIGS. 1 and 2, the seat-harness assembly 300 comprises a seat plate 310 and a backrest 320 connected to each other, the seat plate 310 and the backrest 320 are connected in an L shape, and the seat plate 310 and the backrest 320 are used for the child to sit and lean. Optionally, the seat plate 310 and the backrest 320 are rotatably arranged, and the rotation axis is A. The seat-harness assembly 300 further comprises a guardrail in a U shape, and the guardrail is rotatably connected at the connection between the seat plate 310 and the backrest 320. By rotating the guardrail, the guardrail can be rotated to the front side of the child to protect the child.

[0086] In some embodiments, the seat-harness assembly 300 is integrated with the same structures as the structural member 100, i.e., the seat-harness assembly 300 is also provided with the base 110, the support frame 120, the locking member 113, the second locking slot 111, the mounting slot 112, the control member 130, and the first engagement tooth 140, etc. structures. Details of these structures have been described above, and will not be repeated here. The support frame 120 can be integrated with the guardrail. Such arrangement not only enables the seat-harness assembly 300 and the basket to share the mounting and cooperation structure 210 on the frame assembly 200, but also reduces the design and manufacturing costs.

[0087] The installation and removal processes of the seat-harness assembly 300 are as follows:

[0088] The installation process is as follows: after aligning the seat-harness assembly 300 with the mounting and cooperation structure 210 of the frame assembly 200, the seat-harness assembly 300 is lowered. During this process, the second guide inclined surface at the lower front end of the seat-harness assembly 300 hits the front unlocking member 214, and the front unlocking member 214 is pushed by the second guide inclined surface to move away from the second locking slot 111. At the same time, the locking member 113 on the seat-harness assembly 300 slides backward along the first guide inclined surface after hitting the mounting and cooperation structure 210, so that the seat-harness assembly 300 can continue to be lowered to the fixed position. After the seat-harness assembly 300 is in place, the locking member 113 is inserted into the first locking slot 213 under the drive of the elastic body 116, and the lock tongue 211 connected to the front unlocking member 214 is inserted into the second locking slot 111 under the drive of the elastic member 215. Thus, the assembly is completed.

[0089] The removal process is as follows: as shown in FIGS. 6 and 7, the backrest 320 is unlocked, and the backrest 320 is rotated through the rotation axis A connected to the seat plate 310. During the rotation of the backrest 320, the locking member 113 is driven to disengage from the first locking slot 213, thereby achieving rear unlocking. At the same time, the front unlocking member 214 at the front is pulled inward to move, so that the lock tongue 211 disengages from the second locking slot 111, thereby completing the rear unlocking. After unlocking, the seat-harness assembly 300 is lifted, and thus the disassembly of the seat-harness assembly 300 is completed. Figure 13 and Figure 14 The installation and removal processes of the seat-harness assembly 300 are as follows:

[0090] The installation and removal processes of the structural member 100 are as follows:

[0091] The installation process is as follows: the structure 100 is aligned with the mounting fitting structure 210 of the frame assembly 200, and then the structure 100 is placed down, in the process, the second guide slope at the front lower end of the structure 100 hits the front unlocking piece 214, and the front unlocking piece 214 is pushed to move away from the second lock slot 111 through the second guide slope; at the same time, the locking piece 113 in the structure 100 slides backward along the first guide slope after hitting the mounting fitting structure 210, so that the structure 100 can continue to be placed down to the fixed position; after the structure 100 is placed down to the position below, the locking piece 113 is inserted into the first lock slot 213 under the driving of the elastic body 116, and the lock tongue 211 connected with the front unlocking piece 214 is inserted into the second lock slot 111 under the driving of the elastic piece 215, and the assembly is completed. After the structure 100 is installed to the position, the basket can be installed on the structure 100.

[0092] The removal process is as follows: as shown in Figure 15 The control handle 130 is pulled upward to unlock the engagement of the second engagement teeth 150 of the support frame 120 and the first engagement teeth 140 of the base 110, so that the first engagement teeth 140 and the second engagement teeth 150 are switched to the separated state, the support frame 120 can be rotated through the rotating axis B connected with the base 110, the support frame 120 is rotated forward, and the notch surface in the support frame 120 hits the locking piece 113 in the rotating process, so as to drive the locking piece 113 to slide backward and disengage from the first lock slot 213, thereby realizing the rear unlocking. At the same time, the front unlocking piece 214 is pulled to move inward, so that the lock tongue 211 disengages from the second lock slot 111, and the rear unlocking is completed. After the unlocking, the structure 100 is lifted, and the disassembly of the structure 100 is completed.
