Above, the slider 5 is located above the first shaft 7 . When the vehicle frame is in the unfolded state, the support frame 3 is located behind the first support 1. During the transition of the vehicle frame from the unfolded state to the folded state, the support frame 3 rotates forward toward the first support 1, and the basket frame 4 is opposite to the first support 1. A support 1 slides forward and rotates relative to the first support 1 , wherein the front of the basket 4 moves upwards and the rear of the basket 4 moves downwards to be folded behind the first support 1 .

Specifically, the first bracket 1 has two first support rods 11 arranged on the left and right sides and extending in the up and down direction, and the support frame 3 has two support rods 31 arranged on the left and right sides and extending in the up and down direction. The basket frame 4 is located between the two first support rods 11 and between the two support rods 31 along the left and right directions. 1. The cross bar 42 fixed between the rear parts of the two basket bars 41. Here, the cross bar 42 and the two basket bars 41 are integrally arranged as a U-shaped bar with the opening facing forward.

Each first pole 11 is rotatably connected to a sliding piece 5 through the third shaft 9, and the sliding piece 5 here is specifically a sliding sleeve, and the sliding sleeve is sleeved on the basket rod 41 on the corresponding side in a sliding fit. , the first pole 11 is fixed with a connecting head 12 protruding backward, the lower end of each side supporting rod 31 is pivotally connected to the connecting head 12 around the first axis 7, and the supporting rod 31 is connected with the corresponding side basket at the same time. The lever 41 is pivotally connected about the second shaft 8 . The front end of the basket rod 41 on each side is also fixedly provided with a limiting member 43, and the limiting member 43 is located in front of the sliding sleeve. In this embodiment, the limiting member 43 is specifically an end plug inserted into the rod cavity at the front end of the basket rod 41 . When the vehicle frame is in an unfolded state, the limiting member 43 is against the front end of the sliding sleeve.

When the vehicle frame is in the unfolded state, the basket rod 41 has a first rod segment 411 and a second rod segment 412 connected along the length direction, and the first rod segment 411 is located between the slider 5 and the support rod 31 (that is, the slider 5 and the second shaft 8), the second rod segment 412 is located behind the support rod 31 (that is, the rod segment behind the second shaft 8), and the length of the second rod segment 412 is greater than that of the first rod segment 411 length, which makes the overall length of the basket frame 4 longer.

Referring to the drawings, in this embodiment, the first wheel assembly 10 is a rear wheel assembly, and the second wheel assembly 20 is a front wheel assembly, that is to say, the first support 1 is a rear wheel support, and the second support 2 is a rear wheel assembly. The front wheel support, when the vehicle frame is in the unfolded state, the first support 1 extends obliquely upward from the rear to the front, and the second support 2 extends obliquely upward from the front to the rear, the first support 1 is located behind the second support 2, and the support frame 3 is located behind the first bracket 1, and most of the basket frame 4 is located behind the first bracket 1, which can have a larger size and accommodating space. The vehicle frame also includes a push rod frame 6 extending obliquely from front to rear in an unfolded state. The upper part of the second bracket 2 is pivotally connected to the lower part of the push rod frame 6, and the upper part of the first bracket 1 is pivotally connected to the second frame. On the support 2 , the support frame 3 is rotatably connected between the first support 1 and the push rod frame 6 .

In the unfolded state of the children's stroller of the present embodiment, as shown in Fig. 1 and Fig. 2, the first support 1 and the second support 2 are deployed along the front-to-rear direction, and the basket frame 4 extends along the front-to-rear direction and is mostly overhanging the Behind the first bracket 1, the basket frame 4 can have a larger size and accommodating space, and at the same time, it is also convenient for the user to pick and place items. When the vehicle frame needs to be folded up, as shown in Fig. 4 and Fig. 5, turning the push rod frame 6 downward and backward can drive the push rod frame 6 to rotate relative to the second bracket 2 and the support frame 3, and drive the first The first bracket 1 and the second bracket 2 rotate relative to each other and gradually draw in the front and rear directions. The basket frame 4 is linked to rotate relative to the support frame 3 and slide relative to the first bracket 1 , thereby rotating and retracting relative to the first bracket 1 and the support frame 3 . The folded children's stroller is shown in Fig. 6 and Fig. 7, and its folded structure is compact and takes up less space.
