[0028] The utility model is further described below in conjunction with the accompanying drawings:

[0029] Embodiment 1:

[0030] like Figures 1 to 10 As shown, the first aspect of the utility model provides a child seat reversing device, including a base 1, to which is connected a seat assembly 2 capable of rotating and reversing relative to the base 1, the seat assembly 2 comprising a seat portion 21 rotatably connected to the base 1 and a backrest portion 22 connected to the seat portion 21, a locking structure 23 capable of locking the seat portion 21 and the base 1 is provided between the seat portion 21 and the base 1, a connecting frame assembly 24 capable of providing protection for the child is provided between the backrest portion 22 and the seat portion 21, and an operating member 241 is provided on the connecting frame assembly 24, which can drive the locking structure 23 to unlock after operation so that the seat assembly 2 can rotate and reversal relative to the base 1.

[0031] When the seat assembly 2 needs to be reversed, the locking structure 23 can be unlocked by operating the operating member 241 set on the connecting frame assembly 24. The operating member 241 is set on the connecting frame assembly 24 and is in a conspicuous position so that the user can directly see it. The user does not need to reach under the seat part 21 to feel for the operating member. The child seat reversing device of the utility model is more convenient to operate and unlock.

[0032] like Figures 4 to 5 As shown, the locking structure 23 includes at least two reversing locking positions 231 arranged on the base 1, the seat portion 21 is connected with a driving member 232 which can slide relative to the seat portion 21 after being subjected to an external force, and the seat portion 21 is also connected with a locking member 233 which moves relative to the seat portion 21 and engages in or disengages from the reversing locking position 231 when driven by the driving member 232, a cable 234 which can pull the driving member 232 to slide when the operating member 241 is operated is connected between the driving member 232 and the operating member 241, an elastic member 235 which can keep the locking member 233 in a locked state is provided between the locking member 233 and the seat portion 21, and a reset member 236 which can drive the driving member 232 to reset is provided between the driving member 232 and the seat portion 21. When the locking structure 23 needs to be unlocked, the operating member 241 is operated. After the operating member 241 is operated, the cable 234 is pulled. The cable 234 drives the driving member 232 to slide relative to the seat portion 21 during the movement of the operating member 241. During the sliding process, the driving member 232 drives the locking member 233 to move relative to the seat portion 21. The locking member 233 is separated from the reversing locking position 231 on the base 1 and enters the seat portion 21. At this time, the seat assembly 2 can be rotated and reversed relative to the base 1.

[0033] like Figure 5As shown, the locking member 233 is provided with a first inclined sliding surface 2331, and the driving member 232 is provided with a second inclined sliding surface 2321 which can push the first inclined sliding surface 2331 when the driving member 232 slides, so that the locking member 233 slides upward. When the driving member 232 is pulled by the cable 234 and slides relative to the seat portion 21, the second inclined sliding surface 2321 on the driving member 232 pushes the first inclined sliding surface 2331 on the locking member 233, so that the locking member 233 slides upward relative to the seat portion 21 and leaves the locking position 231 on the base 1. The cooperation between the first inclined sliding surface 2331 and the second inclined sliding surface 2321 can make the driving member 232 push the locking member 233 to slide more steadily and smoothly.

[0034] like Figure 5 As shown, the driving member 232 is also provided with a clearance groove 2332 for the locking member 233 to pass through and to make way for the locking member 233. The clearance groove 2332 can also be used to limit the position where the locking member 233 slides relative to the driving member 232.

[0035] like Figure 7 As shown, the connecting frame assembly 24 includes an armrest frame 242 connected to the backrest portion 22, and the connecting frame assembly 24 also includes a connecting member 243 connected to both the armrest frame 242 and the seat portion 21. The upper part of the connecting member 243 is installed at the front end of the armrest frame 242, and the lower part of the connecting member 243 is installed at the front end of the seat portion 21. The operating member 241 is arranged on the connecting member 243. The armrest frame 242, the connecting member 243, the seat portion 21 and the backrest portion 22 cooperate to form a surrounding frame, so that the child is safer when sitting on the seat.

[0036] like Figure 7 As shown, the operating member 241 is rotatably connected to the connecting member 243, and one end of the cable 234 is connected to the operating member 241, and the other end is connected to the driving member 232. When the operating member 241 is rotated, the operating member 241 pulls the cable 234, and the other end of the cable 234 can pull the driving member 232 to make the locking member 233 disengage from the locking position 231. Figures 9 to 10 As shown, the second aspect of the utility model provides a child stroller, comprising the child seat reversing device described above.

[0037] Embodiment 2:

[0038] The difference between Example 2 and Example 1 is that:

[0039] The backrest 22 is rotatably connected to the seat 21, the connecting frame assembly 24 includes an armrest frame 242 rotatably connected to the backrest 22, and the connecting frame assembly 24 also includes a connecting member 243 rotatably connected to both the armrest frame 242 and the seat 21, the upper part of the connecting member 243 is mounted on the front end of the armrest frame 242, the lower part of the connecting member 243 is mounted on the front end of the seat 21, and the operating member 241 is arranged on the connecting member 243. At this time, the backrest 22 and the connecting member 243 can be rotated and folded relative to the seat 21, and the armrest frame 242 can be rotated and folded relative to the backrest 22 and the connecting member 243, thereby reducing the space occupied by the child seat and making it easier to store and transport.
