Different embodiments of the collapsible stroller 100 of the present invention will now be described with reference to fig. 1-11, respectively. The rear seat 120' is conventional in the art and will not be described in detail.

Referring to fig. 1-6, in an embodiment of the foldable stroller 100 of the present invention, the front seat 120 disposed in front of the stroller 100 includes a seat plate 121, the seat plate 121 is slidably connected to the seat tube 130, and when the frame 110 is folded, the seat plate 121 is driven to slide along the seat tube 130 toward the rear of the stroller 100 to reduce the folded volume of the stroller 100.

As shown in fig. 1-2, a sliding sleeve 140 is fixed on 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 comprises a cross bar 150 and a driving member 160, wherein the cross bar 150 is disposed below the seat plate 121, and two ends of the cross bar 150 are respectively fixed to the front legs 112, one end of the driving member 160 is pivotally connected to the protrusion 121a below the seat plate 121 through a rotating shaft, and the other end of the driving member 160 is engaged with 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 to slide along the seat tube 130 to the rear of the stroller 100 by the driving member 160, and during this process, the relative position between the cross bar 150 and the seat plate 121 changes with the folding of the frame 110.

With continued reference to fig. 1-6, the collapsing process of the stroller 100 of this embodiment will be described. When the rider 111 is unlocked from the engaging portion 113a, the operating portion 111a of the rider 111 is pushed to pivot the rider 111 forward of the stroller 100, and simultaneously the front leg 112 is pivoted close to the rear leg 113, so that the cross bar 150 moves backward along with the front leg 112 synchronously, when the cross bar 150 moves, the driving member 160 pulls the seat plate 121 to slide backward of the stroller 100 along the seat tube 130, and when the frame 110 is completely folded, the seat plate 121 is not located at the highest point of the frame 110, thereby reducing the volume of the folded frame 110.

Referring now to fig. 7-8, another embodiment of the collapsible stroller 100 of the present invention differs from the previous embodiment only in the structure of the driving member 160, and the other structures are the same, and only the differences between the two will be described below, and the descriptions of the same parts will be omitted.

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 an inclined slot 161, the cross bar 150 is movably disposed in the inclined slot 161, so that the position of the cross bar 150 relative to the seat plate 121 can be changed, and two ends of the cross bar 150 are respectively fixed to the front legs 112. When the stroller 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 inclined groove 161, and during this process, the cross bar 150 moves in the inclined groove 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 are pivoted close to the rear legs 113, so that the cross bar 150 moves backward along with the front legs 112, and therefore the cross bar 150 interacts with the side wall of the inclined groove 161 and moves in the inclined groove 161, thereby pushing the seat plate 121 to slide along the seat tube 130 to the rear of the stroller 100, and when the frame 110 is completely folded, the seat plate 121 is not located at the highest point of the frame 110, thereby reducing the volume of the folded frame 110.

Referring now to fig. 9-11, yet another embodiment of the collapsible stroller 100 of the present invention will be described. 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 through a pivot 141 (see fig. 11), so that the seat plate 121 can rotate relative to the seat tube 130. The cross bar 150 is pivotally connected to the seat plate 121, and specifically, the cross bar 150 is rotatably connected to the lower side of the seat plate 121 through a connecting member 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, the two ends of the cross bar 150 are respectively fixed to the front legs 112, and the seat plate 121 is driven by the cross bar 150 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 is an arc structure corresponding to the outer diameter of the cross bar 150, the arc structure is clamped outside the cross bar 150, and the 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 cannot be changed.

In this embodiment, the remaining structure of the stroller 100 is the same as that of the above-described 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 handlebar 111 and the engaging portion 113a are unlocked from each other, the operating portion 111a of the handlebar 111 is pushed to pivot the handlebar 111 toward the front of the stroller 100, and simultaneously the front leg 112 is pivoted toward 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 toward the rear of the stroller 100 along the seat tube 130, and simultaneously the seat plate 121 rotates around 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 completely folded, the seat plate 121 is not located 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 a stroller 100 having a front seat 120 and a rear seat 120', and that the present invention is applicable to a stroller 100 having only one seat, as is well known to those skilled in the art.

Because the foldable stroller 100 of the present invention comprises 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-back direction of the stroller 100, and the folding of the frame 110 can drive the seat plate 121 to slide toward the rear of the stroller 100 relative to the seat tube 130, the seat plate 121 is not located at the highest point of the frame 110 after the stroller 100 is completely folded, thereby reducing the volume of the folded stroller 100, facilitating storage and carrying, and the stroller 100 has a simple structure and a simple folding operation.
