When the stroller transitions from the open state to the folded state, the first limiting top piece 31 and the second limiting top piece 41 are separated from the first sliding block with the rotation of the first bottom frame 3 and the second bottom frame 4 respectively. The sleeve 53 and the second sliding sleeve 63 can be relatively slidable between the first sliding rod 51 and the first side frame 1 , and the second sliding rod 52 and the second side frame 2 can be relatively slidable.

A pull rod 9 is rotatably connected to the second side frame 2 . Specifically, the pulling rod 9 includes a lowering rod 91 whose lower part is rotatably connected with the lower part of the second side frame 2 , and an upper pulling rod 92 which is telescopically connected with the lowering rod 91 .

Folding principle of children's car:

When folding the stroller, pull up the connection between the first bottom frame 3 and the second bottom frame 4 to make the first bottom frame 3 and the second bottom frame 4 rotate and move closer to each other, thereby driving the first side frame 1 At the same time, due to the rotation of the first bottom frame 3 and the second bottom frame 4, the first limiting top piece 31 and the second limiting top piece 41 are separated from the first sliding sleeve 53 and the second limiting top piece 41. Two sliding sleeves 63, so that one end of the first sliding rod 51 and the first side frame 1 and one end of the second sliding rod 52 and the second side frame 2 can be relatively slidable. The mutual closeness of the second side frames 2 makes the rods in the first cross frame 5 , the second cross frame 6 and the cross brace 7 rotate and move closer to each other. Retract the lower rod 91 and the upper rod 92 , and rotate the rod 9 to make it close to the second side frame 2 . until the whole car is folded.

The folding stroller in the above embodiment, through its structural design, in the open state, the setting of the connecting assembly makes the entire chassis of the stroller have sufficient strength. During the folding process of the stroller, the cross frame design of the connecting assembly makes the connecting assembly Participate in the folding of the whole vehicle without affecting the folded volume of the whole vehicle. The folded stroller is flat as a whole, which greatly reduces the occupied space and is very convenient to store and carry.

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present invention, and the purpose thereof is to enable those who are familiar with the technology to understand the content of the present invention and implement accordingly, and cannot limit the protection scope of the present invention with this. All equivalent changes or modifications made according to the spirit of the present invention shall be included within the protection scope of the present invention.
