[0022] The present invention is further described below with reference to specific embodiments. Figure 1 —5:

[0023] A motorcycle windshield electric lifting mechanism includes a connecting bracket 1 fixed to the front of the motorcycle, the connecting bracket 1 is provided with a lifting slide rail in the up and down direction, and a lifting movable seat 3 for connecting the windshield is slidably connected to the lifting slide rail through a sliding block 2, and a driving rack 4 is provided on the lifting movable seat 3 along its sliding direction. A driving gear engaged with the driving rack 4 is rotatably connected to the connecting bracket 1, and the driving gear is connected to the servo motor 5 fixed to the connecting bracket 1. The servo motor 5 drives the driving gear to engage with the driving rack 4 to drive the lifting movable seat 3 to move up and down on the lifting slide rail.

[0024] The overall structure of the utility model is compact and simple, the design is reasonable and the cost is low. With the help of the matching structure of the driving rack 4 and the driving gear, the servo motor 5 drives the lifting and moving seat 3 to move up and down on the lifting slide rail. Its transmission is stable, reliable and easy to adjust.

[0025] Among them, in order to further improve the lifting and moving stability of the lifting and moving seat 3, in this embodiment, two lifting slide rails are provided and are respectively located on the left and right sides of the connecting bracket 1, and the left and right sides of the lifting and moving seat 3 are respectively slidably matched with the lifting slide rails on the corresponding sides.

[0026] Considering that during windshield adjustment and vehicle driving, there is a gap in the connection between the windshield and the adjustment structure, which can easily cause shaking and abnormal noise, the sliding block 2 is provided with two or more mating holes at intervals on one side wall. Each mating hole is equipped with a ball 6 that can roll on the lifting rail, and a mating spring 7 is installed between the ball 6 and the bottom of the mating hole. The ball 6, under the elastic action of the mating spring 7, compensates for the gap between the sliding block 2 and the lifting rail, effectively preventing the shaking of the windshield during adjustment and vehicle driving.

[0027] At the same time, in order to enable the sliding block 2 to be assembled into the lifting slide rail and facilitate the sliding block 2 to move up and down in the lifting slide rail, in this embodiment, the specific structure adopted by the lifting rail is: a rail groove 8 is opened on the connecting bracket 1 in the up and down directions, and a rail cover plate 9 is provided at the notch of the rail groove 8. The lifting slide rail is formed between the rail cover plate 9 and the rail groove 8, and the sliding block 2 is arranged in the rail groove 8, and the matching hole is arranged on the side wall of the sliding block 2 facing the rail cover plate 9, and an arc groove is opened on the side wall of the sliding block 2 facing the bottom of the rail groove 8. Matching strip through holes 10 are axially opened on both side walls of the rail groove 8 between the sliding block 2 and the bottom surface of the rail groove 8. The lifting seat 3 is rotatably connected to a roller 12 located in the rail groove 8 through a connecting pin 11 passing through the two matching strip through holes 10, and the roller 12 is rollingly fitted between the arc groove and the bottom surface of the rail groove 8.

[0028] In addition, in order to further improve the stability of the driving rack 4 in the lifting and lowering movement relative to the connecting bracket 1, a limiting strip-shaped through hole 13 is opened on the driving rack 4 along the sliding direction of the lifting and moving seat 3, and a fixed angle plate 14 is provided on the connecting bracket 1. One end of the fixed angle plate 14 is fixed on the connecting bracket 1, and the other end is slidably fitted in the limiting strip-shaped through hole 13 through a limiting axle pin, and the middle part of the fixed angle plate 14 is inserted on the axis of the driving gear through a positioning axle pin 15.

[0029] At the same time, the servo motor 5 can be directly linked to the driving gear. In this embodiment, the servo motor 5 is fixed on the back of the connecting bracket 1, the lifting and moving seat 3 and the driving gear are arranged on the front of the connecting bracket 1, and the output end of the servo motor 5 is connected to the driving gear through the gearbox 16.

[0030] Furthermore, in order to ensure the meshing transmission between the driving gear and the driving rack 4, and to prevent the driving gear from continuing to drive the rotation when the driving rack 4 drives the lifting and moving seat 3 to move to the upper and lower extreme positions, thereby causing the driving gear and the driving rack 4 to slip or even wear, an upper limit switch 17 and a lower limit switch 18 are provided on the connecting bracket 1 located on one side of the driving rack 4 along the axial interval of the driving rack 4, and an upper limit stop wall that can cooperate with the trigger end of the upper limit switch 17 and a lower limit stop wall that can cooperate with the trigger end of the lower limit switch 18 are provided on the driving rack 4. The control assembly is electrically connected to the upper limit switch 17 and the lower limit switch 18, and the control switch controls the opening and closing state of the servo motor 5 according to the signals of the upper limit switch 17 and the lower limit switch 18.

[0031] When the driving gear and the driving rack 4 are matched to the extreme position, in order to prevent the sliding block 2 from having a matching gap with the end of the lifting slide rail, which in turn causes the windshield to shake, the upper and lower ends of the lifting slide rail are respectively connected to a damping baffle 20 that can move along the lifting slide rail through a damping spring 19. The sliding block 2 moves up and down and can abut against the corresponding damping baffle 20.

[0032] In addition, the specific structure of the cooperation between the upper limit switch 17 and the lower limit switch 18 and the driving rack 4 is as follows: a limit groove 21 is opened on the side of the driving rack 4 away from the driving gear, and the trigger ends of the upper limit switch 17 and the lower limit switch 18 are both located in the limit groove 21, and the upper limit retaining wall and the lower limit retaining wall are the upper and lower end walls of the limit groove 21 respectively.

[0033] The above embodiment is only one of the preferred embodiments of the present invention and is not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made based on the shape, structure, and principle of the present invention should be included in the scope of protection of the present invention.
