For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The present embodiment is described in detail below with reference to the accompanying drawings:

[0026] This embodiment provides a folding bicycle. Please refer to the accompanying drawings in the specification. Figure 1-7 .

[0027] like Figure 1-7 As shown, a folding bicycle comprises a vertical front vehicle support 1 and a rear vehicle support 2, the bottom legs of the front vehicle support 1 and the rear vehicle support 2 are respectively provided with universal wheels 3, the bottoms of the front vehicle support 1 and the rear vehicle support 2 are rotatably connected by a horizontal rotating folding rod 4 symmetrically on both sides, and the columns of the front vehicle support 1 and the rear vehicle support 2 above the horizontal rotating folding rod 4 are fixed with fixed sleeves 5 with openings facing each other, and both ends of a horizontal vehicle body support 6 are respectively provided with plug-in parts 7 extending outside the vehicle body support 6, and the plug-in parts 7 at each end are respectively plugged into the corresponding fixed sleeves 5, so that the vehicle body support 6 is supported and fixed between the front vehicle support 1 and the rear vehicle support 2. The fixed sleeve 5 can be rotatably connected to the column, such as a hinge structure that rotates upward, which can be rotated 90 degrees, and can be rotated from a vertical state to a horizontal state at most. When folding, it is necessary to first pull out the plug-in part 7 of the vehicle body bracket 6 from the corresponding fixed sleeve 5, that is, remove the vehicle body bracket 6 first. Therefore, when the vehicle body is in an open state, the folding rod 4 can be used to further support the vehicle body bracket 6 by horizontally rotating it, and both can ensure that the four columns of the front vehicle bracket 1 and the rear vehicle bracket 2 are always vertical, thereby improving the overall carrying capacity of the vehicle body. In order to facilitate hand pushing, the upper ends of the front vehicle bracket 1 and the rear vehicle bracket 2 are respectively rotatably provided with outwardly rotating folding armrests 12.

[0028] Specifically: each horizontal rotating and folding rod 4 has two rod bodies 401, and a rotating sleeve 402 is vertically fixed at both ends of each rod body 401. The rotating sleeve 402 at one opposite end of each rod body 401 is sleeved together, and the rotating sleeve 402 at the other end of each rod body 401 is sleeved on the corresponding front vehicle support 1 and rear vehicle support 2 columns. In this way, after the vehicle body support 6 is disassembled, the horizontal rotating and folding rods 4 on each side are rotatably connected by the vertical rotating sleeve 402, so that they can only be rotated and folded in the horizontal direction. In order to avoid interference between the left and right horizontal rotating and folding rods 4 when folding, the left and right horizontal rotating and folding rods 4 can be staggered up and down, and when the vehicle body is unfolded, the folding part of each horizontal rotating and folding rod 4 is slightly bent inward relatively, so that when the vehicle body is in a folded state, the front vehicle support 1 and the rear vehicle support 2 are folded close to each other through the horizontal rotating and folding rod 4.

[0029] In order to facilitate folding, the vehicle body support 6 also adopts a folding structure, such as being composed of a front and rear frame 601, and the front and rear frames 601 are rotatably connected by a hinge 602, and when the front and rear frames 601 are horizontal, the opposite ends of the hinge 602 are close together, so that after the vehicle body support 6 is fully opened, it is rotated into place by the hinge 602 for limiting, and when it is horizontal, the contact position of the hinge 602 provides downward pressure on the frame to increase the load-bearing capacity of the vehicle body. When the vehicle body support 6 is folded, the front and rear frames 601 can be rotated downward around the hinge 602, and support blocks 603 are respectively provided at the bottom of the front and rear frames 601. The support blocks 603 are supported on the horizontal rotating folding rod 4 on one side to provide upward supporting force. The vehicle body support 6 itself has a strong supporting effect, and is supported on the horizontal rotating folding rod 4 by the support blocks 603, so the supporting strength of the vehicle body support 6 is greatly improved, and it can carry heavier goods and can also be better used for people to lie down and rest.

[0030] For more convenient use, a bearing frame 9 that is opened horizontally outward is rotated inside the front vehicle bracket 1 or the rear vehicle bracket 2 through a hinge 8, and a seat frame 10 is rotatably connected to the outside of the bearing frame 9 through the hinge 8. The two ends of the outer side of the bearing frame 9 are located in the column hooks 11 of the front vehicle bracket 1 or the rear vehicle bracket 2, and the outer end of the seat frame 10 is fixedly connected to the column of the front vehicle bracket 1 or the rear vehicle bracket 2 through a soft rope. The soft rope is elastic and convenient for folding the seat frame 10. Through the design of the hinges 8 at various locations, that is, the hinges 8 at various locations rotate at a certain angle, and the bearing frame 9 is in a vertical state, the seat frame 10 can be rotated 90 degrees into the vehicle body, that is, the seat frame 10 is equivalent to being horizontally located in the vehicle body to form a folding seat, which can realize the seat function of the seat frame 10; similarly, when the bearing frame 9 and the seat frame 10 are rotated outward along the hinge 3 at the bottom of the bearing frame 9, the hinge can also make the bearing frame 9 almost horizontal with the vehicle body bracket 6, and the bearing frame 9 is used as an extension space of the vehicle floor for lying down and sleeping.

[0031] In order to better support the vehicle roof, the upper ends of the columns of the front vehicle bracket 1 and the rear vehicle bracket 2 are respectively provided with ceiling support rods 15. Specifically: the upper ends of the columns of the front vehicle bracket 1 and the rear vehicle bracket 2 are respectively covered with fixing blocks 13, and the other end of each fixing block 13 is respectively provided with a vertical socket 14, and a plug 16 is fixed to the lower end of the ceiling support rod 15, and the plug column 17 on one side of the plug 16 is located in the socket 14 of the fixing block 13.

[0032] In order to provide a better ride, a seat can also be placed on the other side of the folding seat. A horizontal support crossbar 18 is fixed to the top of the front vehicle bracket 1, and a hook structure 20 is provided on the back of the backrest of the seat 19 placed on the vehicle body bracket 6, and the hook structure 20 is hung on the horizontal support crossbar 18.

[0033] Of course, the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
