Detailed Implementation

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0026] The structure of the electric windshield lifting mechanism assembly in this embodiment of the utility model is as follows: Figures 1 to 6As shown, it includes a mounting base 1, a windshield bracket 2, a rack 3, a drive motor 4, and a guide structure. The windshield bracket 2 is used to mount the windshield (not shown in the figure). The rack 3 is arranged in the vertical direction and its upper and lower ends are fixedly connected to the mounting base 1. The windshield bracket 2 can move up and down relative to the mounting base 1. The guide structure is located between the mounting base 1 and the windshield bracket 2. The guide structure provides guidance for the vertical movement of the windshield bracket 2. The drive motor 4 is fixed on the windshield bracket 2, and a drive gear 41 is installed at the output end of the drive motor 4. The rack 3 has a rack portion 31 arranged along its length direction. The rack portion 31 meshes with the drive gear 41. In this embodiment, in practical applications, the drive motor 4 drives the drive gear 41 to rotate, and then through the meshing transmission between the drive gear 41 and the rack portion 31, the drive motor 4 and the windshield bracket 2 fixedly connected to it are driven to move up and down under the guidance of the guide structure, thereby realizing the electric control of the windshield lifting. This structure offers the advantage of easy control, allowing users to adjust the windshield height with simple operation. Furthermore, in one usage environment, this electric windshield lifting mechanism assembly can interconnect with other electronic systems on the motorcycle. For example, the windshield can automatically rise to reduce wind resistance when the motorcycle reaches a certain speed, and automatically lower to increase ventilation at low speeds. The guide structure design ensures smooth and stable lifting movement between the drive motor 4 and the windshield bracket 2, enhancing the overall user experience. Overall, this structure not only improves operational convenience but also enhances the motorcycle's riding comfort and safety.

[0027] See Figures 1 to 3 The windshield bracket 2 includes a left bracket 21, a right bracket 22 and a connecting frame 23. The connecting frame 23 fixes the left bracket 21 and the right bracket 22 to form a stable overall structure. The drive motor 4 is fixed on the connecting frame 23.

[0028] To enhance the stability of the windshield bracket 2, guide structures are provided between the left bracket 21 and the right bracket 22 and the mounting base 1. This design can effectively reduce the swaying or tilting of the windshield bracket 2 during the lifting and lowering process, thereby improving the overall stability.

[0029] Referring to 4, the drive motor 4 has an outer shell 40. A limiting sliding hole 42 is formed between the outer shell 40 and the windshield bracket 2. The limiting sliding hole 42 and the rack rod 3 are slidably sleeved. This structure can strengthen the connection between the drive motor 4 and the windshield bracket 2 and the rack rod 3, thereby ensuring the integrity of the structure. At the same time, it can ensure that the drive gear 41 and the rack part 31 reliably mesh.

[0030] Further, see Figure 3The guide structure includes a limiting guide rod 11 fixed on the mounting base 1 and a linear bearing 24 fixed on the windshield bracket 2. The limiting guide rod 11 is arranged in the vertical direction, and the linear bearing 24 is slidably sleeved on the limiting guide rod 11. This ensures that the linear bearing 24 can slide flexibly on the limiting guide rod 11, thereby improving the smoothness of the structure and avoiding jamming during the lifting and lowering movement of the windshield bracket 2.

[0031] See Figure 1 and Figure 3 As shown, limit switches 12 are provided at both the upper and lower ends of the mounting base 1. When the windshield bracket 2 moves to its uppermost or lowermost position, the corresponding limit switch 12 is triggered to ensure that the windshield bracket 2 can stop moving in time when it reaches its limit position, thereby preventing mechanical damage caused by excessive travel and improving the safety and reliability of the system. The limit switches 12 can be micro switches, limit switches, etc.

[0032] See Figure 2 and Figure 3 An elongated hole 13 is provided on the mounting base 1 along the vertical direction. The drive motor 4 is located in the elongated hole 13. The position of the drive motor 4 can be avoided through the elongated hole 13, thereby optimizing space utilization, improving the compactness of the structure, and avoiding the increase in the size of the mechanism due to the interference between the position of the drive motor 4 and the mounting base 1.

[0033] See Figure 6 As shown, the rack rod 3 is provided with a sliding groove 30 extending in the vertical direction, the rack part 31 is disposed in the sliding groove 30, and the drive gear 41 extends into the sliding groove 30 to mesh with the rack part 31, thereby enhancing the stability of the structure.

[0034] To ensure reliable fixation between the windshield and the windshield bracket 2, the windshield bracket 2 is provided with a support plane 25 and a fixing hole 26. The support plane 25 is attached to the surface of the windshield to form a stable support for the windshield, and then screws are used to cooperate with the fixing hole 26 to effectively fix the windshield.

[0035] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the protection scope of this invention.
