[0002] The steering columns of existing low-speed four-wheeled vehicles all adopt a fixed installation structure, which makes it impossible for users to adjust the angle of the steering column and change the position of the steering wheel connected to the steering column. As a result, different users cannot adjust the position of the steering wheel according to their own body shape, which has limitations in use.

[0003] In view of the above problems, it is necessary to study a steering column adjustment structure for low-speed four-wheeled vehicles, which can adjust the angle of the steering column to facilitate driving of low-speed four-wheeled vehicles by users of different body types. Utility Model Content

[0004] The purpose of this utility model is to provide a steering column adjustment structure for a low-speed four-wheeled vehicle, which can adjust the angle of the steering column to facilitate driving of low-speed four-wheeled vehicles by users of different body types.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A steering column adjustment structure for a low-speed four-wheeled vehicle includes a fixed seat, a steering column, and an adjustment mechanism. The upper end of the steering column is connected to a steering wheel, and the lower end of the steering column is hinged to the fixed seat. The adjustment mechanism includes a connecting seat, an adjusting seat, and a self-locking gas spring. The upper end of the self-locking gas spring is hinged to the middle of the steering column, and the lower end of the self-locking gas spring is connected to the connecting seat. The adjusting seat is hinged to the connecting seat, and the adjusting seat movably presses the needle valve of the self-locking gas spring. An elastic reset member is fitted between the adjusting seat and the connecting seat. The elastic reset member is used to drive the adjusting seat back to a position where the needle valve of the self-locking gas spring is not pressed. The connecting seat is hinged to the fixed seat.

[0007] The elastic reset component is a torsion spring, which is fitted at the pivot point between the adjusting seat and the connecting seat. The first end of the torsion spring abuts against the adjusting seat, and the second end of the torsion spring abuts against the connecting seat.

[0008] The adjusting seat is provided with a slot for the first end of the torsion spring to be engaged.

[0009] The connecting seat includes two opposing connecting side plates and a connecting top plate connecting the two connecting side plates. The connecting top plate is connected to the lower end of the self-locking gas spring, and the two connecting side plates are hinged to the adjusting seat. The second end of the torsion spring abuts against the connecting top plate.

[0010] The adjustment seat has a kick plate.

[0011] The adjusting seat includes an adjusting plate, a connecting plate, and a kick plate. The adjusting plate is hinged to the connecting seat and can be used to press the needle valve of the self-locking gas spring. The upper and lower ends of the connecting plate are respectively connected to the adjusting plate and the kick plate. The kick plate is intersecting with both the adjusting plate and the connecting plate.

[0012] The adjustment mechanism also includes two connecting seats that are rotatably connected to both sides of the connecting seat, and the connecting seats are fixedly connected to the fixed seat.

[0015] The fixed seat is provided with an arc-shaped limiting groove, and the steering column is connected to a limiting post that slides in contact with the limiting groove. The limiting post moves against both sides of the limiting groove.

[0016] With the above solution, when this utility model is applied to a low-speed four-wheeled vehicle, the upper end of the steering column is connected to the steering wheel, and the fixing seat is fixedly engaged with the vehicle body. When the user needs to adjust the steering column angle, the user presses the adjusting seat, which presses the needle valve of the self-locking gas spring, thus unlocking the self-locking gas spring. At this time, the user can rotate the steering column to adjust its angle, and the self-locking gas spring will extend and retract accordingly with the change in the steering column angle. After the user adjusts the steering column angle to the desired angle, the user releases the pressure on the adjusting seat. The adjusting seat resets under the action of the elastic reset member, thus releasing the pressure on the needle valve of the self-locking gas spring. At this time, the self-locking gas spring is locked and cannot extend or retract, thereby fixing the steering column. Attached Figure Description
