[0024] The overall structure of the present invention 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. The 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 there is a gap in the connection between the windshield and the adjustment structure during the adjustment of the windshield and the driving of the vehicle, which is easy to shake and produce abnormal noise, two or more matching holes are arranged on one side wall of the sliding block 2, and each matching hole is provided with a ball 6 that can roll on the lifting slide rail, and a matching spring 7 is provided between the ball 6 and the bottom of the matching hole. That is, the ball 6 compensates for the matching gap between the sliding block 2 and the lifting slide rail under the elastic action of the matching spring 7, so as to effectively solve the shaking phenomenon of the windshield during the adjustment and driving of the vehicle.

[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 track groove 8 is opened on the connecting bracket 1 in the up and down directions, and a track cover plate 9 is covered at the notch of the track groove 8, and the lifting slide rail is formed between the track cover plate 9 and the track groove 8, and the sliding block 2 is arranged in the track groove 8, and the matching hole is arranged on the side wall of the sliding block 2 facing the track cover plate 9, and an arc groove is opened on the side wall of the sliding block 2 facing the bottom of the track groove 8, and matching strip through holes 10 are axially opened on the two side walls of the track groove 8 between the sliding block 2 and the bottom surface of the track groove 8, and the lifting and moving seat 3 is rotatably connected to a roller 12 located in the track groove 8 through a connecting pin shaft 11 passing through the two matching strip through holes 10, and the roller 12 is rollingly matched between the arc groove and the bottom surface of the track 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.

[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 arranged 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 arranged 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, thereby causing the windshield to swing, the upper and lower ends of the lifting slide rail are respectively connected with a damping baffle 20 that can move along the lifting slide rail through a damping spring 19, and the sliding block 2 can move 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 stop wall and the lower limit stop wall are respectively the upper and lower end walls of the limit groove 21.
