In the unfolded state, the axis of the tenth axis X10 and the axis of the eleventh axis X11 both extend in the up-down direction, the axis of the twelfth axis X12 and the axis of the thirteenth axis X13 both extend in the front-back direction, and there is no parallel relationship between the axes of the above-mentioned axes.

[0071] In this embodiment, the push rod 41 comprises an upper push rod 411 and a lower push rod 412, the lower part of the lower push rod 412 constitutes a first end and is rotatably connected to the rear support 1, the inner side of the lower part of the lower push rod 412 is provided with a push handle linkage 42, the upper part of the lower push rod 412 is rotatably connected to the lower part of the upper push rod 411, the upper part of the upper push rod 411 constitutes a second end, and the second cross support frame 9 is arranged between the upper parts of the two side upper push rods 411. Specifically, on the left and right sides, the upper part of the lower push rod 412 is rotatably connected to the lower part of the upper push rod 411 around the fourteenth axis X14, and the axis of the fourteenth axis X14 extends in the left-right direction. The upper parts of the two upper push rods 411 are folded towards each other, the two second cross support rods 91 are rotatably connected to the upper parts of the upper push rods 411 on the same side, and in the unfolded state, the upper parts of the upper push rods 411 and the second cross support rods 91 constitute the push handle of the stroller, and the user drives the stroller forward by pushing the upper parts of the upper push rods 411 or the second cross support rods 91.

[0072] The stroller further comprises a first wheel 101 and a second wheel 102, the first wheel 101 has two groups arranged on the left and right sides of the lower part of the front support 3, and the second wheel 102 has two groups arranged on the left and right sides of the lower part of the rear support 1. Specifically, the two groups of first wheels 101 are arranged on the lower part of the two front legs 31 respectively, and the two groups of second wheels 102 are arranged on the lower part of the two side support rods 11 respectively.

[0073] In the unfolded state, the two side support rods 11 gradually extend outward along the left-right direction from front to back, and the distance between the upper ends of the two side support rods 11 is greater than the distance between the lower ends, so that the distance between the two groups of first wheels 101 is greater, thereby enabling the first wheels 101 to provide more stable support. When the stroller is in the unfolded state, the distance between the two groups of first wheels 101 along the left-right direction is greater than the distance between the two groups of second wheels 102 along the left-right direction. During the conversion of the stroller from the unfolded state to the folded state, the distance between the two groups of first wheels 101 decreases, and the distance between the two groups of second wheels 102 remains unchanged. In the present embodiment, the two groups of second wheels 102 are arranged on the outer sides of the two side support rods 11, and the two side support rods 11 extend downward and toward each other, and the distance between the lower ends is less than the distance between the upper ends, thereby reducing the distance between the two groups of second wheels 102 and reducing the size of the stroller along the left-right direction when folded.

[0074] When folding the stroller, referring to Figures 4 to 6 the locking of the locking mechanism is released, and the upper push rod 411 is rotated along the a direction about the fourteenth axis X14, so that the upper push rod 411 rotates relative to the lower push rod 412 and is folded toward each other, and the connection between the upper push rod 411 and the lower push rod 412 moves downward. The upper push rod 411 drives the lower push rod 412 to flip backward along the b direction about the third axis X3 and to fold toward the rear side of the rear support 1. During the flipping of the lower push rod 412, the push handle linkage 42 drives the rear seat plate 22 to flip along the c direction about the first axis X1, and the lower part of the second connecting rod 72 drives the sliding member 5 to slide downward along the length direction of the side support rod 11. The sliding member 5 drives the first connecting rod 71 to slide downward, and the front part of the first connecting rod 71 drives the front support leg 31 to flip backward along the d direction about the second axis X2 relative to the front side of the rear support 1. The folding continues to reach the final folded state. During the folding of the stroller along the front-rear direction, the distance between the lower ends of the two front support legs 31 and the distance between the upper parts of the two upper push rods 411 are reduced, and the distance between the lower parts of the two upper push rods 411 and the distance between the upper parts of the two lower push rods 412 are also reduced, thereby driving the first cross support frame 8 and the second cross support frame 9 to fold along the left-right direction, and the two groups of first wheels 101 also fold toward each other, so that the stroller folds along the left-right direction.

[0075] When the trolley is folded, the front support legs 31, rear support 1, lower push rod 412, and upper push rod 411 are folded together from front to back. The front seat plate 21 is flipped to a position approximately parallel to the plane of the front support 3. This can also be understood as the front seat plate 21 extending vertically and positioned between the two front support legs 31. The rear seat plate 22 extends horizontally, positioned approximately horizontally between the connecting parts on both sides. The distance between the second ends of the two front support legs 31 is less than the distance between their first ends. The two first cross braces 81 form an acute angle, as do the two second cross braces 91. The distance between the two sets of first wheels 101 is less than the distance between the two sets of second wheels 102, and the two sets of first wheels 101 are folded together between the two sets of second wheels 102 in the left-right direction. In this state, the rotating connection between the upper push rod 411 and the lower push rod 412, along with the second wheels 102, is supported on the ground. In this embodiment, the dimension of the upper part of the rear support 1 along the left and right direction determines the dimension of the upper part of the trolley along the left and right direction in the folded state, and the distance between the two sets of second wheels 102 determines the dimension of the lower part of the trolley along the left and right direction in the folded state.

[0076] In summary, the trolley structure of this embodiment is simple. The trolley can be folded not only in the front-to-back direction but also in the left-to-right direction. Simultaneously, its seat frame 2 folds during the folding process relative to the rear support 1. The folding operation is simple: just press down and push forward the upper push rod 411 to drive the support rod and rear support 1 together in the front-to-back direction. During this process, the width of the rear support 1 remains unchanged in the left-to-right direction, and the second ends of the support rods away from the rear support 1 move closer together in the left-to-right direction, thus causing the trolley to fold in the left-to-right direction. There is no linkage mechanism between the rear support 1 and the support rods to drive the support rods to fold in the left-to-right direction. In the folded state, the front seat plate 21 flips to be approximately perpendicular to the rear seat plate 22, minimizing the trolley's folded volume. The trolley has a neat and compact overall structure after folding, occupies little space, is easy to store at home and carry when going out, and provides a good user experience.
