As shown in fig. 1-2, a sliding sleeve 140 is fixed at the side of the seat plate 121, and the sliding sleeve 140 is slidably sleeved on the seat tube 130.

As shown in fig. 3-6, the foldable stroller 100 further includes a cross bar 150 and a driving member 160, wherein the cross bar 150 is disposed below the seat plate 121, two ends of the cross bar are respectively fixed to the front legs 112, one end of the driving member 160 is pivotally connected to a protrusion 121a below the seat plate 121 through a rotating shaft, and the other end of the driving member 160 is clamped on the cross bar 150 and pivotally connected thereto, so that the relative position between the cross bar 150 and the seat plate 121 can be changed. When the frame 110 is folded, the cross bar 150 pulls the seat plate 121 along the seat tube 130 by the driving member 160 to slide to the rear of the stroller 100, and in this process, the relative position between the cross bar 150 and the seat plate 121 changes along with the folding of the frame 110.

With continued reference to fig. 1-6, the folding process of the stroller 100 of the present embodiment will be described. When the handle 111 is released from the engaging portion 113a, the handle 111a of the handle 111 is pushed to pivot the handle 111 forward of the stroller 100, and the front leg 112 is pivoted to close to the rear leg 113, so that the cross bar 150 moves backward synchronously with the front leg 112, and when the cross bar 150 moves, the seat plate 121 is pulled by the driving member 160 to slide backward of the stroller 100 along the seat tube 130, and when the frame 110 is fully folded, the seat plate 121 is not at the highest point of the frame 110, so that the volume of the folded frame 110 is reduced.

Referring now to fig. 7-8, another embodiment of the collapsible pushchair 100 of the present invention is different from the above embodiment only in the structure of the driving member 160, and the other structures are the same, and only the difference between the two structures will be described below, and the same parts will not be repeated.

As shown in fig. 8, in the present embodiment, the driving member 160 is fixed below the seat plate 121, the driving member 160 is provided with a chute 161, and the cross bar 150 is movably disposed in the chute 161, so that the position of the cross bar 150 relative to the seat plate 121 can be changed, and both ends of the cross bar 150 are respectively fixed to the front legs 112. When the frame 110 is folded, the seat plate 121 is pushed to slide along the seat tube 130 to the rear of the stroller 100 by the interaction of the cross bar 150 and the chute 161, and during this process, the cross bar 150 moves in the chute 161 to change the relative position between the cross bar 150 and the seat plate 121.

With continued reference to fig. 7-8, the collapsing process of the stroller 100 of this embodiment will be described. When the frame 110 is folded, the front legs 112 pivot relative to the rear legs 113 to move the cross bar 150 rearward along with the front legs 112, so that the cross bar 150 interacts with the side walls of the chute 161 and moves within the chute 161 to push the seat plate 121 to slide along the seat tube 130 toward the rear of the stroller 100, and when the frame 110 is fully folded, the seat plate 121 is not at the highest point of the frame 110, thereby reducing the volume of the folded frame 110.

A further embodiment of the collapsible pushchair 100 of the present invention will now be described with reference to figures 9-11. In this embodiment, the sliding sleeve 140 is slidably sleeved on the seat tube 130, and the sliding sleeve 140 is pivotally connected to a side portion of the seat plate 121 (see fig. 11) through a pivot 141, so that the seat plate 121 can rotate relative to the seat tube 130. The cross bar 150 is pivoted to the seat plate 121, specifically, the cross bar 150 is rotatably connected under the seat plate 121 by a connecting piece 170, so that the cross bar 150 can rotate relative to the seat plate 121, but the relative position between the cross bar 150 and the seat plate 121 is not changed; meanwhile, two ends of the cross bar 150 are respectively fixed on the front legs 112, and the cross bar 150 drives the seat plate 121 to slide and rotate relative to the seat tube 130.

With continued reference to fig. 10-11, the middle portion of the connecting member 170 has an arc structure corresponding to the outer diameter of the cross bar 150, the arc structure is clamped outside the cross bar 150, and two ends of the connecting member 170 are respectively fixed to the seat plate 121, so that the cross bar 150 can only rotate relative to the seat plate 121, but the relative position between the two can not be changed.

In this embodiment, the rest of the structure of the stroller 100 is the same as that of the above embodiment, and the description thereof will not be repeated.

With continued reference to fig. 9-11, the collapsing process of the stroller 100 of the present embodiment will be described. When the handle 111 and the engaging portion 113a are released from each other, the handle 111a of the handle 111 is pushed to pivot the handle 111 forward of the stroller 100, and simultaneously the front leg 112 is pivoted towards the rear leg 113, and the cross bar 150 moves backward along with the front leg 112, so that the cross bar 150 drives the seat plate 121 to slide backward of the stroller 100 along the seat tube 130, and simultaneously the seat plate 121 rotates about the pivot shaft 141, that is, the seat plate 121 slides and rotates relative to the seat tube 130, and when the frame 110 is fully folded, the seat plate 121 is not at the highest point of the frame 110, thereby reducing the volume of the folded frame 110.

It is to be understood that the present invention is not limited to strollers 100 having front and rear seats 120, 120', and that the present invention is applicable to strollers 100 having only one seat, as is well known to those skilled in the art.

Because the foldable stroller 100 of the present invention includes a foldable frame 110, a seat tube 130 disposed on the frame 110, and a seat plate 121 slidably connected to the seat tube 130, wherein the seat tube 130 extends along the front-rear direction of the stroller 100, and the folding of the frame 110 can drive the seat plate 121 to slide towards the rear of the stroller 100 relative to the seat tube 130, the seat plate 121 is not at the highest point of the frame 110 after the stroller 100 is completely folded, thereby reducing the folded volume of the stroller 100, facilitating storage and carrying, and the stroller 100 has a simple structure and simple folding operation.

The structure of the frame 110 and the folding operation of the stroller 100 according to the present invention are well known to those skilled in the art, and will not be described in detail herein.
