Referring to fig. 1 and 2a, and 3 to 6, in one embodiment of the present invention, a ride vehicle having a folded state and a constant height is provided, which includes a frame 100 having a length direction L and a width direction W, a liner 200 disposed inside the frame 100, and wheels 300 disposed below the frame 100. As shown in fig. 1, frame 100 includes a bottom bracket 110, a column 140, and a side bracket 150. The side blocking frame 150 is disposed between two adjacent columns 140, and forms an accommodating space 111 with the bottom bracket 110. The two adjacent columns are two columns adjacent to each other in the longitudinal direction L or the width direction W. The receiving space 111 may be used to install the liner 200 and to load articles.

As shown in fig. 2a, 2b and 3, the bottom bracket 110 comprises two side bars 120 arranged in parallel along the length direction and a crosspiece arranged between the two side bars 120. Side bars 120 are two-fold bars that can be rotated and folded in a vertical plane, for example, at least a portion of folded side bars 120 may be away from bottom bracket 110, and folding of side bars 120 affects ride height. Further, the side bar 120 is rotatably folded in a vertical plane inside the side bar 150. The bottom bracket 110 itself forms a bottom plane ABCD, which is perpendicular to the vertical plane of the edge bar 120 that is pivotally folded.

The crosspieces can be folded in the width direction W, i.e. collapsed or folded. The cross pieces may be two-fold rods that can be folded in a horizontal plane, and the cross pieces 130 using two-fold rods are divided into two groups, the folding directions of the cross pieces in different groups are different, and the number of the cross pieces in one group may be one or two. In other embodiments the rungs may also be flexible strips, for example cloth strips.

As shown in fig. 3 and 4, four columns 140 are respectively disposed at the corner positions of the frame 100 and connected to the bottom bracket 110. The upright column 140 is provided with an upper fixing member 141 and a lower fixing member 143, and the end of the side bar 120 is hinged to the lower fixing member 143.

The side frames 150 have first and second coupling portions 151 and 152 at both sides thereof to hinge the respective posts 140. Side rails 150 include any two adjacent posts between which a rail is located on the side of frame 100. For any one of the uprights, the side frames 150 have a first connecting portion 151 and a second connecting portion 152 connected thereto. The first connection 151 is axially fixed relative to the upright 140 and the second connection 152 is axially movable relative to the upright 140. Specifically, the first connecting portion 151 is hinged to the upper fixing member 141, and the second connecting portion 152 is hinged to the sliding member 142 provided on the pillar 140.

The side guard frame 150 includes at least one scissor mechanism, each scissor structure is composed of a pair of scissor rods 153 hinged to each other, the scissor rods 153 of two adjacent scissor structures are hinged in a one-to-one correspondence manner, and the scissor rod 153 of the uppermost scissor mechanism is hinged to the upright column 140.

As shown in fig. 3, 5 and 6, compared with fig. 1-2 a, the design of the pull handle 400 is also increased, and the pull handle 400 is hinged to the bottom bracket 110 and can be contracted and/or folded.

The folding of the bottom bracket 110 is achieved by rotating and folding the side rods 120 and folding the cross pieces. When the traveling vehicle is folded, the second connecting part 152 moves axially along the upright posts 140, the sliding part 142 slides axially along the upright posts towards the wheel direction, the width of the side blocking frame 150 is correspondingly shortened, the overall height of the traveling vehicle is not influenced, and the four upright posts 140 are gathered towards the center, so that the folding of the traveling vehicle is realized. The width of the side frames 150 is shortened accordingly, meaning that the side frames 150 are shortened in both the length direction L and the width direction W.

All possible combinations of the technical features of the embodiments described above may not be described for the sake of brevity, but should be considered as being within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features. Features of different embodiments are shown in the same drawing, which is to be understood as also disclosing combinations of the various embodiments concerned.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, and these are all within the scope of protection of the present application.
