Technical Field

[0001] The utility model relates to the technical field of vehicle structures, and particularly relates to a steering wheel adjusting mechanism. Background Art

[0002] A golf cart, also known as an electric golf cart or a pneumatic golf cart, is an environment-friendly passenger vehicle specially designed for golf courses.

[0003] In the related art, a golf cart includes a frame, a body, wheels, and a steering wheel. A user sits in the body and controls the direction of the wheels through the steering wheel.

[0004] Specifically, the steering wheel is mounted on the frame through a mounting tube.

[0005] In order to enable the steering wheel to adapt to users of different heights, the steering wheel of a golf cart is usually adjustable. The conventional steering wheel adjustment method is to manually loosen the mounting tube and the frame and then manually pull and adjust the height of the steering wheel. After adjustment, the mounting tube and the frame are manually locked again.

[0006] However, the existing steering wheel adjustment method of a golf cart is troublesome and laborious to operate, which is not conducive to the operation of the user. Content of the Utility Model

[0007] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a steering wheel adjusting mechanism, which can simplify the adjustment operation of the steering wheel and make the adjustment operation of the steering wheel more labor-saving.

[0012] A gas spring, one end of which is hinged to the frame and the other end of which is hinged to the mounting tube. The gas spring expands and contracts to drive the mounting tube to swing up and down.

[0013] A steering wheel adjusting mechanism according to an embodiment of the utility model has at least the following beneficial effects:

[0014] 1. The utility model realizes the angle adjustment of the steering wheel by setting a vehicle frame, a steering wheel and a connecting component. The connecting component includes an installation pipe and an installation frame. One end of the installation pipe is connected to the installation frame, the other end of the installation pipe is rotatably connected to the steering wheel, and the installation frame is hinged to the vehicle frame.

The gas spring expands and contracts to drive the installation pipe to swing up and down. Thus, the gas spring can drive the installation pipe to swing up and down, and the angle of the installation pipe can be automatically fixed after the gas spring stops expanding and contracting. Further, the manual pulling and adjusting of the steering wheel and the manual locking and fixing of the angle of the steering wheel are eliminated, the adjustment operation of the steering wheel is simplified, and the adjustment operation of the steering wheel is made more labor-saving.

The first pin shaft 170 is rotatably connected to the vehicle frame 100. A first bolt 180 and a first threaded hole 190 for positioning and fixing are provided between the first bushing 160 and the first pin shaft 170. Thus, when the first bolt 180 is loosened, the first pin shaft 170 can rotate and slide inside the first bushing 160, facilitating the assembly of the first pin shaft 170 on the first bushing 160. After the first pin shaft 170 is assembled, the first bolt 180 is screwed into the first threaded hole 190, so that the cooperation between the first bolt 180 and the first threaded hole 190 can quickly position and fix the first pin shaft 170 and the first bushing 160. Furthermore, the assembly efficiency of the first pin shaft 170 can be improved.

[0052] Further, the first threaded hole 190 is provided on the first pin shaft 170, and the first threaded hole 190 extends along the radial direction of the first pin shaft 170.

[0057] Further, the two second bushings 200 are respectively located on both sides of the mounting bracket 140, and the two second bushings 200 respectively limit both sides of the mounting bracket 140, thereby making the swing of the mounting bracket 140 more stable.

[0058] Refer to Figure 5 , in some specific embodiments, a third bushing 210 is further provided on the mounting bracket 140. A second pin shaft 220 is provided within the third bushing 210. The second pin shaft 220 is arranged parallel to the first pin shaft 170. The vehicle frame 100 is provided with a first sliding groove 230 for accommodating the sliding of the second pin shaft 220. Both ends of the first sliding groove 230 respectively limit the maximum sliding positions of the second pin shaft 220, thereby facilitating the limitation of the angular range of the up-and-down swing of the steering wheel 110 and avoiding the excessive up-and-down swing angle of the steering wheel 110.

[0059] In some specific embodiments, a second bolt 240 and a second threaded hole 250 for positioning and fixing are provided between the third bushing 210 and the second pin shaft 220. Thus, when the second bolt 240 is loosened, the second pin shaft 220 can rotate and slide within the third bushing 210, facilitating the assembly of the second pin shaft 220 onto the third bushing 210. After the second pin shaft 220 is assembled, the second bolt 240 is screwed into the second threaded hole 250, enabling the cooperation between the second bolt 240 and the second threaded hole 250 to quickly position and fix the second pin shaft 220 and the third bushing 210. Furthermore, the assembly efficiency of the second pin shaft 220 can be improved.

[0060] Furthermore, the second threaded hole 250 is provided on the second pin shaft 220 and extends along the radial direction of the second pin shaft 220. Thus, the second bolt 240 can pass through the side wall of the third bushing 210 from the radial outside of the third bushing 210 and then be threadedly connected to the second threaded hole 250, facilitating the operations of tightening and loosening the second bolt 240.

[0063] For the gas spring 150, one end of the gas spring 150 is hinged to the vehicle frame 100, and the other end of the gas spring 150 is hinged to the mounting tube 130. The gas spring 150 expands and contracts to drive the mounting tube 130 to swing up and down.

[0064] In this embodiment, by providing the gas spring 150, one end of the gas spring 150 is hinged to the vehicle frame 100, and the other end of the gas spring 150 is hinged to the mounting tube 130. The gas spring 150 expands and contracts to drive the mounting tube 130 to swing up and down. Thus, the gas spring 150 can drive the mounting tube 130 to swing up and down, and after the gas spring 150 stops expanding and contracting, it can automatically fix the angle of the mounting tube 130. Furthermore, the angle of the steering wheel 110 can be automatically adjusted and fixed, eliminating the need for manual pulling and adjusting the steering wheel 110 and manually locking and fixing the angle of the steering wheel 110, simplifying the adjustment operation of the steering wheel 110 and making the adjustment operation of the steering wheel 110 more labor-saving.
