[0001] The utility model relates to the technical field of box - type folding electric vehicles, in particular to a rotatable folding handlebar and a box - type folding electric vehicle of a box - type folding electric vehicle. Background Art

[0002] The front frame of a box - type folding electric vehicle needs to be folded, which also poses a challenge to the structure of the handlebar.

[0003] For example, a Chinese patent with the publication number CN115649335A discloses a box - type folding electric bicycle, which includes a box body and a front wheel assembly. The front wheel assembly includes a foldable handlebar mechanism, i.e., a handlebar. The handlebar is folded by folding forward. The handlebar includes a U - shaped handlebar support frame, a folding vertical pipe, and a foldable handle. Among them, when the handlebar mechanism is folded, due to the structure of the U - shaped handlebar support frame extending backward, the U - shaped handlebar support frame will protrude beyond the front wheel. In order to enable the front wheel assembly to be placed inside the box after folding, it is necessary to limit and fix it after increasing the folding angle or increase the length of the box body.

[0004] Due to the limited internal space of the box - type folding electric vehicle, the above - mentioned handlebar structure needs to be improved so that the U - shaped handlebar support frame does not protrude beyond the front wheel after folding. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, to provide a rotatable folding handlebar and a box - type folding electric vehicle of a box - type folding electric vehicle, first rotate the handlebar and then fold it forward. The folded handlebar will not protrude beyond the front wheel, will not occupy the internal space of the box of the box - type folding electric bicycle, and will not affect the overall folding of the frame.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a rotatable folding handlebar of a box - type folding electric vehicle includes:

[0010] The U - shaped handlebar support frame is used for connecting the handlebar. The handlebar is a foldable handlebar, and the handlebar is installed at the upper ends of the two side walls of the U - shaped handlebar support frame. There is a certain inclination angle between the U - shaped handlebar support frame and the vertical direction;

[0011] When in the riding state, the U-shaped handlebar support frame inclines towards the side close to the vehicle body;

[0012] After the rotating shaft rotates 180°, the pin shaft between the upper joint and the lower joint is located on the side far from the vehicle body, which is used to enable the folding joint to fold towards the side far from the vehicle body.

[0013] Furthermore, the upper ends of the two side walls of the U-shaped handlebar support frame are connected by an arc-shaped connecting piece, and the arc-shaped connecting piece protrudes towards the side far from the vehicle body, which is used to make way for the front wheel in the storage state.

[0014] Furthermore, one side of the connecting surface of the upper joint and the lower joint is rotationally connected by a pin shaft, and the other side is limited and locked by a buckle.

[0015] Furthermore, the upper end of the connecting rod is fixedly connected to the lower end of the U-shaped handlebar support frame, and the lower end of the connecting rod is fixedly connected to the upper end of the upper joint.

[0028] Figures 1-6 A rotatable and foldable handlebar of a box - type folding electric vehicle shown includes:

[0029] A rotating mechanism 1, the rotating mechanism includes a rotating shaft 11 and a shaft sleeve 12 rotatably sleeved outside the rotating shaft 11, and the shaft sleeve 12 is used for fixedly connecting with the vehicle body 5;

[0030] A folding joint 2, the folding joint 2 includes an upper joint 21 and a lower joint 22 rotatably connected by a pin shaft,

[0031] Through the cooperation of the rotating shaft 11 and the folding joint 2, first rotate and then fold the handlebar forward. After folding, the handlebar will not protrude beyond the front wheel, will not occupy the internal space of the box of the box - type folding electric bicycle, and will not affect the overall folding of the vehicle frame.

[0032] Among them, the upper end of the upper joint 21 is fixedly connected to the U-shaped handlebar support frame 3 through the connecting rod 4, and the lower end of the lower joint 22 is fixedly connected to the fork arm 7 of the front wheel 6 through the rotating shaft 11.

[0033] The U-shaped handlebar support frame 3 is used to connect the handlebar 8, and the handlebar 8 is also a foldable handlebar. The handlebar 8 is installed at the upper ends of the two side walls of the U-shaped handlebar support frame 3, and there is a certain inclination angle between the U-shaped handlebar support frame 3 and the vertical direction.

[0034] In the riding state, the U-shaped handlebar support frame 3 inclines towards the side close to the vehicle body 5.

[0035] After the rotating shaft 11 rotates 180°, the pin shaft between the upper joint 21 and the lower joint 22 is located on the side away from the vehicle body 5, which is used to enable the folding joint 2 to fold towards the side away from the vehicle body 5.

[0036] The upper ends of the two side walls of the U-shaped handlebar support frame 3 are connected by an arc-shaped connecting piece 31, and the arc-shaped connecting piece 31 protrudes towards the side away from the vehicle body 5, which is used to make way for the front wheel 6 in the storage state.

[0037] One side of the connecting surface of the upper joint 21 and the lower joint 22 is rotatably connected by a pin shaft, and the other side is limited and locked by a lock 23.

[0038] The upper end of the connecting rod 4 is fixedly connected to the lower end of the U-shaped handlebar support frame 3, and the lower end of the connecting rod 4 is fixedly connected to the upper end of the upper joint 21.

[0039] A box-type folding electric vehicle includes a box body. The front and rear sides of the box body have openings. A lifting mechanism and a vehicle body 5 are arranged in the box body.
