[0006] To further improve the above technical solution, screw holes are provided at the four corners of the bottom plate of the mounting bracket for locking with the vehicle frame.

[0007] Further, the steering column connecting member and the gas spring connecting member are aligned along the central axis of the bottom plate.

[0008] Further, the gas spring includes an adjustment handle. Pressing the adjustment handle can make the piston of the gas spring move up and down, thereby realizing the angle adjustment of the steering column.

[0009] Further, when the adjustment handle is released, the gas spring is self-locked and the steering column is locked.

[0010] Further, the steering wheel is mounted on the steering column through a spline.

[0011] Further, it further includes a mobile phone holder, and the mobile phone holder is mounted on the steering column.

[0012] Further, the gas spring is connected to the hinge seat through an M8 screw.

[0021] The technical solution of the present utility model will be described in detail below with reference to the drawings, but the protection scope of the present utility model is not limited to the described embodiments.

[0022] Embodiment 1: The steering column adjustment mechanism for low-speed electric vehicles as shown in Figure 1 includes a mounting bracket 2, a steering column 1, a gas spring 3, a steering wheel 4 and a mobile phone holder 5. The steering wheel 4 is mounted on the top of the steering column through a spline to ensure stability and accuracy during operation.

[0023] As shown in Figure 2 , Figure 3As shown, the mounting bracket 2 has a bottom plate, on which a steering column connector and a gas spring connector are provided. The steering column connector and the gas spring connector are aligned along the central axis of the bottom plate. The four corners of the bottom plate are fixed to the vehicle frame through four screw holes to ensure the stability of the structure. The steering column connector is of a U-shaped frame structure. Rotating shaft holes are provided on two opposite side walls of the U-shaped frame, and through holes corresponding to the U-shaped frame are provided on the bottom plate. The bottom of the steering column passes through the through holes and is connected to the rotating shaft holes through rotating shaft bolts on the side wall of the steering column. The gas spring connector is two relatively arranged hinge seats, and the bottom end of the gas spring extends between the two hinge seats and is hinged through a connector.

[0024] As Figure 3 shown, the steering shaft 1 is fixed to the mounting bracket 2 through a rotating shaft bolt; the structure of the rotating shaft bolt is as Figure 4 shown.

[0025] The bottom end of the gas spring 3 is fixedly connected to the hinge seat on the mounting bracket 2 through an M8 screw, and the top end is connected to the steering column 1, so as to realize the angle adjustment of the steering column.

[0026] During adjustment, the user holds the gas spring adjustment handle and presses it. The handle drives the gas spring piston to move up and down, thereby driving the column to perform front and rear angle adjustment. After adjusting to a suitable position, the handle is released, and the self-locking function of the gas spring automatically locks the current angle to complete the adjustment.

[0027] As Figure 5 shown, the mobile phone bracket 5 is adhered to an appropriate position of the steering column to facilitate the driver to fix the mobile phone while driving.

[0028] The utility model adopts a gas spring structure, enabling the steering column to perform front and rear angle adjustment according to the driver's needs, and automatically locking the adjusted angle through the self-locking function, which is convenient to operate and has high safety.
