Description

Technical Field

[0001] The utility model relates to the technical field of vehicle accessories, in particular to a motorcycle windshield lifter. Background Art

[0002] Motorcycles, electric vehicles, tricycles, etc. on the market are basically equipped with windshields to reduce the damage to the human body caused by wind and sand or debris blowing in the face of the vehicle during the moving process. For example, the current motorcycle windshield usually adopts a fixed and non-adjustable structure, which cannot meet the comfort and safety requirements of people of different heights for driving motorcycles. In order to solve the above problems, a motorcycle windshield lifter with adjustable windshield height is produced.

[0003] The existing motorcycle windshield lifter includes a frame, a bracket for fixing the windshield, and a driving device for driving the bracket to move up and down. The bracket is an integrated or bilaterally symmetrical split type. A slider is connected to the bracket, and a slide rail that slides with the slider is fixed to the frame. The slider and the slide rail of the existing motorcycle windshield lifter are easily stuck when dust or small particles of sand enter, so that the lifter often needs to be cleaned and repaired, which shortens the service life. Utility Model Content

[0004] Based on the above problems, the purpose of the utility model is to provide a motorcycle windshield lifter with stable displacement, small starting torque and long service life.

[0005] In view of the above problems, the following technical solutions are provided: a motorcycle windshield lifter, comprising a frame, a bracket for fixing the windshield, and a driving device for driving the bracket to move up and down, the bracket being an integrated type or a bilaterally symmetrical split type, a slide rail being installed on the frame, a guide member being connected to the slide rail, a guide block being connected to a side of the bracket facing the frame, a transmission member being rotatably connected to the guide block, and the transmission member being in sliding engagement with the guide member.

[0006] In the above structure, the starting torque when the drive device drives the bracket to move can be reduced by slidingly cooperating with the guide member, thereby extending the service life of the drive device, and improving the stability of the bracket when it is displaced, thereby improving the structural strength and reliability of the utility model. The transmission member is rotatably connected to the guide block so that dust or small particles of mud and sand enter the slide rail without being stuck, and the transmission member can still move relative to the guide member, thereby avoiding the need for frequent cleaning, disassembly, and maintenance of the utility model, reducing manual labor, and extending the service life of the utility model. The rotation of the transmission member can reduce the friction of the transmission member and the guide member in the displacement, further reducing the starting torque of the drive device.

[0007] The utility model is further configured that at least two transmission members are spaced apart in the displacement direction of the guide block, two guide members are provided and are respectively located on both sides of the slide rail, and guide grooves are provided in the radial direction of the transmission member to slide with the guide members.

[0008] In the above structure, the guide groove can facilitate the sliding cooperation between the transmission member and the guide member, and can improve the smoothness of the relative displacement of the transmission member relative to the guide member, thereby improving the reliability of the utility model. By providing at least two transmission members and two guide members, the stability of the displacement of the guide block can be improved, thereby further improving the reliability of the bracket during displacement.

[0009] The utility model is further configured such that the transmission member is located inside the slide rail or sleeved on the outside of the slide rail. When the transmission member is located inside the slide rail, each transmission member is offset to both sides relative to the central axis of the slide rail.

[0010] The above structure can reduce the blocking effect caused by dust and small particles of sand, so that the transmission member and the guide member can be smoothly displaced, thereby improving the reliability of the utility model. By arranging the transmission member in the slide rail, and each transmission member is offset to both sides relative to the central axis of the slide rail, the transmission member can be rolled relative to the guide member, thereby improving the smoothness of the transmission member displacement, thereby improving the reliability and stability of the utility model.

[0011] The utility model is further configured that the transmission member adopts a grooved bearing.

[0012] The above structure can facilitate the installation of the transmission member, thereby improving the convenience of assembly of the utility model.

[0013] The utility model is further configured that the guide member adopts a cylindrical shaft, and the guide member is integrally arranged with the slide rail or riveted on the slide rail.

[0014] In the above structure, the guide member is integrated with the slide rail, which can facilitate its production, thereby improving the convenience of its assembly. If the guide member is riveted on the slide rail, it is convenient for the manufacturer to select guide members of different materials for assembly according to actual use conditions, thereby extending its service life.

[0015] The utility model is further configured that both ends of the slide rail are provided with limit seats, and a buffer pad is provided on one side of the limit seat facing the slide rail.

[0016] In the above structure, the guide block can be limited by setting a limit seat, and the impact force between the limit seat and the guide block can be reduced by setting a buffer pad, thereby improving the stability of the structure of the utility model and reducing the generation of noise.

[0017] The utility model is further configured that the buffer pad is fastened to the limiting seat by a limiting bolt, and the limiting bolt is correspondingly abutted and matched with the guide member.

[0018] In the above structure, the buffer pad can be fixed by setting the limiting bolt, and the end of the guide member can be abutted and limited, thereby improving the stability of the guide member and improving the reliability of the utility model.

[0019] The utility model is further configured that the buffer pad is provided with a buffer portion protruding toward the sliding block.

[0020] The above structure can facilitate the buffer pad to better buffer the guide block, thereby improving the buffer effect of the buffer pad.

[0021] The utility model is further configured that an elastic groove is provided in the middle of the buffer portion.

[0022] With the above structure, the elastic force of the buffer portion can be increased, and thus the buffering capacity thereof can be further improved.

[0023] The utility model is further configured that the slide rail is mounted on the frame by rivets.

[0024] The above structure can improve the connection strength between the slide rail and the frame and the stability of the structure. BRIEF DESCRIPTION OF THE DRAWINGS
