[0066] The adjustment assembly 20 also includes a limit member 23, which is connected to the second end 212 and is arranged on the same side of the first adjustment member 21 as the second adjustment member 22. The limit member 23 is suitable for abutting against the second adjustment member 22 to limit the rotation angle of the second adjustment member 22, so that when the second adjustment member 22 rotates under the drive of the second driving member 30, it will not turn to the side of the first adjustment member 21 facing the frame 300, so as to ensure that the second adjustment member 22 can accurately contact the road surface 2000, thereby preventing the safety of the driver and passengers from being endangered when the two-wheeled vehicle 1000 tips over.

[0067] Please refer to Figure 2, the first adjusting member 21 is provided with a first through hole 215, and the first through hole 215 runs through two opposite surfaces of the first adjusting member 21. Optionally, the first through hole 215 is provided in the aforementioned first rod 213. Optionally, there are multiple first through holes 215, and the multiple first through holes 215 are arranged at intervals on the first rod 213. Optionally, the first through hole 215 is extended along the aforementioned axis 301, and may also have an angle with the axis 301, without limitation. Optionally, in the orthographic projection in the direction of the axis 301, the contour shape of the first through hole 215 may be rectangular, circular, trapezoidal, non-circular, etc., without limitation. Optionally, the aforementioned second rod 214 is provided with a second through hole (not shown), and the structure and number of the second through hole are similar to those of the first through hole 215, which can be used as a reference and will not be repeated.

[0068] The first adjusting member 21 is provided with a first through hole 215 which penetrates two opposite surfaces of the first adjusting member 21 , thereby making the mechanical structure of the first adjusting member 21 more stable, improving the rigidity and stability of the first adjusting member 21 , and reducing the weight of the first adjusting member 21 .

[0069] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship of terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" are based on the orientation or positional relationship described in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0070] What is disclosed above is only a preferred embodiment of the present application, and it certainly cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiment and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
