[0033] REFERENCE Figure 1 Figure 8 For one embodiment of the present application, an automatic foldable child stroller is provided, which comprises:

[0034] The frame unit 100 comprises a push rod assembly 101, a front support assembly 102, a rear support assembly 103 and a frame folding linkage assembly 104, the frame unit 100 and the foldable child seat 200 are installed through the fixed seat 203, and the front support assembly 102 and the rear support assembly 103 are rotatably installed;

[0035] ​The foldable child seat 200 comprises a fixed seat 203, a seat surface 202 rotating relative to the fixed seat 203, and a backrest frame 201;

[0036] The locking mechanism 300 comprises a backrest locking assembly, a seat surface locking assembly, and a frame locking assembly. The backrest locking assembly is arranged between the backrest frame 201 and the fixed seat 203, and comprises a backrest reset spring 305, a sliding block locking piece 306, and a backrest frame unlocking piece 307. The seat surface locking assembly is arranged between the seat surface 202 and the fixed seat 203, and comprises a linkage 301, a reset spring 302, a locking tooth 303, and a seat surface unlocking piece 304. The frame locking assembly is arranged between the fixed seat 203 and the push rod assembly 101, and comprises a frame unlocking button 308, a frame locking gear 309, and a reset spring 310. The backrest reset spring 305 and the sliding block locking piece 306 are both mounted in the fixed seat 203. The backrest frame unlocking piece 307 is mounted on the backrest frame 201. The linkage 301, the reset spring 302, the locking tooth 303, and the seat surface unlocking piece 304 are all mounted on the fixed seat 203. The frame unlocking button 308, the frame locking gear 309, and the reset spring 310 are all mounted in the inner part of the lower end joint of the push rod assembly 101.

[0037] When the backrest frame 201 rotates forward and exceeds the backrest adjustment range, the backrest frame 201 is in a non-use state. At this time, the seat surface unlocking piece 304 can release the locking of the seat surface locking assembly. The seat surface unlocking piece 304 pushes against the frame unlocking button 308 and moves outward, and triggers the frame locking gear 309 to move outward and compress the reset spring 310. At this time, the frame unit 100 is in an unlocked state, and the automatic folding of the frame unit 100 can be realized. When the frame unit 100 is opened, the reset spring 310 resets the frame locking gear 309, thereby realizing the frame locking function. Therefore, the folding and unfolding of the child stroller is facilitated, the process is simple and intuitive, and the convenience of use is greatly improved.

[0038] When the backrest frame 201 rotates relative to the seat surface 202 within the backrest angle adjustment range, the seat surface unlocking piece 304 cannot release the locking of the seat surface locking assembly. When the backrest frame 201 rotates forward and exceeds the backrest adjustment range, the backrest frame 201 is in a non-use state. At this time, the seat surface unlocking piece 304 can release the locking of the seat surface locking assembly. The seat surface unlocking piece 304 pushes against the frame unlocking button 308 and moves outward, and triggers the frame locking gear 309 to move outward and compress the reset spring 310.

[0039] The lower end of the front support assembly 102 and the lower end of the rear support assembly 103 are both fixedly mounted with a tire assembly 105. The setting of the tire assembly 105 facilitates the movement of the child seat.

[0040] Working principle: when the backrest frame unlocking piece 307 is pulled, the sliding block locking piece 306 is rotated and the backrest reset spring 305 is compressed, the locking between the backrest frame 201 and the seat surface 202 is released, so that the backrest frame 201 and the seat surface 202 reach the non-use state of the seat, at this time the backrest frame 201 can be folded; the seat surface unlocking piece 304 is pulled, the locking tooth 303 is driven through the seat surface unlocking piece 304 and the linkage 301 and the reset spring one 302 is compressed, and is moved to the unlocking direction, so that the seat surface 202 and the fixed seat 203 are unlocked, at the same time the seat surface unlocking piece 304 is pressed against the frame unlocking button 308 and is moved outward, and the frame locking gear 309 is touched and moved outward to compress the reset spring two 310, at this time the frame unit 100 reaches the unlocking state, that is, the frame unit 100 can be automatically folded, the child seat is completely in the unlocking state, the seat surface 202 and the frame unit 100 are folded, and the child seat is completely folded, wherein the contents not described in detail in the description belong to the prior art known to those skilled in the art.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
