When the frame 100 is converted from the unfolded state to the folded state, as shown in fig. 3 and 4, the locking of the frame 100 by the locking mechanism (not shown in the figures) is released, the handle bar 22 is pressed down, the lower push rod 211 slides down along the length extension direction of the sliding part 32 on each of the left and right sides of the frame 100, so that the first connecting rod 31 rotates downward around the first rotation center line a, and the push rod 21 and the front support rod 11 gradually get closer together in the front-rear direction; the relative approach of the push rod 21 and the front support rod 11 drives the rear support rod 51 to rotate upwards around the third rotation center line c, and the rear support rod 51 and the lower push rod 211 gradually move relatively closer; the seat post 71 rotates backward around the fourth rotation center line d and gradually gathers between the front support rod 11 and the push rod 21 in the front-rear direction; the second rod section 212b slides downward along the length direction of the first rod section 212a, the second rod section 212b gradually shrinks into the rod cavity of the first rod section 212a, the first rod section 212a slides downward along the length direction of the lower push rod 211, and the first rod section 212a gradually shrinks into the rod cavity of the lower push rod 211.

When the frame 100 is in the folded state, the front portion of the rear bracket 5, the lower portion of the push rod bracket 2 and the lower portion of the front bracket 1 are close to each other, the push rod bracket 2 is positioned between the two sets of front wheel assemblies 200 in the left-right direction, the front wheel assemblies 200 are positioned below the push rod bracket 2, and the two sets of rear wheel assemblies 300 are positioned between the two sets of push rods 21 in the left-right direction. Specifically, as shown in fig. 5 and 6, on each of the left and right sides of the vehicle frame 100, the front stays 11 and the push rods 21 are relatively closed, the closed front stays 11 extend substantially in parallel with the push rods 21, the rear stays 51 are closed inside the push rods 21, and the front end portions of the rear stays 51, the lower end portions of the push rods 21, and the lower end portions of the front stays 11 are closed to each other; the third connecting rod 61, the seat rod 71 and the seat supporting rod 81 are relatively folded together, and the three folded parts are positioned between the front supporting rod 11 and the lower push rod 211 in the vertical direction; the front wheel assembly 200 is positioned below the push rod 21, and the rear wheel assembly 300 is folded at the inner side of the lower push rod 211; the upper push rod 212 is in a retracted state relative to the lower push rod 211, the first rod segment 212a is retracted in the rod cavity of the lower push rod 211, and the second rod segment 212b is retracted in the rod cavity of the first rod segment 212 a.

The stroller has a pushing use state when the frame 100 is in the unfolded state, as shown in fig. 1 and 2, when the stroller is in the pushing use state and the frame 100 is in the unfolded state, the front wheel assembly 200 and the rear wheel assembly 300 are supported on the ground together, and at this time, the handle bar 22 is pushed forward, and the stroller can be pushed to travel.

When the stroller frame 100 is folded and the stroller needs to be towed, as shown in fig. 7 and 8, a user only needs to lift the handle bar 22 upward to extend the folded stroller frame 100 obliquely from front to back and then to back, and the front wheel assembly 200 is supported on the ground; the upper push rod 212 is pulled backward so that the upper push rod 212 and the lower push rod 211 are in an opened state, and at this time, the user can tow the stroller by pulling the grip lever 22.

Specifically, when the child stroller is in a towing use state, the child stroller has a high towing gear and a low towing gear which can adapt to the user difference avatar. Based on the above-mentioned conversion process from the folded state to the towing use state, the handle bar 22 is pulled upward, so that only the first bar section 212a extends upward from the bar cavity of the lower push bar 211, and at this time, the stroller is in the low towing gear position, and the handle bar 22 is pulled backward, so that the stroller can be towed to travel. Based on the above-mentioned conversion process from the folded state to the towing use state, the handle bar 22 is pulled upward, so that the first bar section 212a extends upward from the bar cavity of the lower push bar 211, and the second bar section 212b extends upward from the bar cavity of the first bar section 212a, at this time, the stroller is in the high towing gear position, and the handle bar 22 is pulled rearward, so that the stroller can be towed to travel.

In some other embodiments, the front wheel assembly 200 is a universal wheel assembly, and the front wheel assembly 200 is disposed at the bottom of the extension rod 112 in a universal rotation manner, so that when the stroller is in a pushing use state, the stroller can flexibly switch the driving direction thanks to the arrangement of the universal wheel assembly; when the child stroller is in a towing use state, the driving direction can be flexibly converted due to the arrangement of the universal wheel assembly, and the towing is easier and more labor-saving.

In conclusion, the stroller of the present invention occupies a small space after being folded; and the folded stroller can be towed for storage and convenient transportation.

The above-mentioned embodiments are merely illustrative of the technical idea and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered in the scope of the present invention.
