When the wind shielding mechanism works, when the wind shielding glass plate is lower, the driving assembly 400 operates and drives the driving lifting assembly 300 to drive the wind shielding support 200 to move in the first direction, and at the moment, the wind shielding glass plate arranged on the wind shielding support 200 is lifted relative to the wind shielding base 100 in the first coordinate direction under the action of the wind shielding support 200, which is equivalent to increase the height of the wind shielding glass plate; when the windshield glass plate is higher, the driving assembly 400 operates and drives the driving lifting assembly 300 to drive the windshield support 200 to move in the second direction, and at this time, the windshield glass plate arranged on the windshield support 200 descends relative to the windshield base 100 in the first coordinate direction under the action of the windshield support 200, which is equivalent to reducing the height of the windshield glass plate. Therefore, the wind shielding mechanism can be adjusted according to the height of a driver, so that the wind shielding glass plate of the driver plays a role in guiding the direction of airflow, and has a certain evading effect on some tiny obstacles, thereby reducing the influence of the wind shielding glass plate on the visual field of the driver and improving the safety of the driver in the driving process.

It should be noted here that the wind-shielding bracket 200 may be directly fixed to the threaded slider 302, or may be further driven by other components. When directly fixed on the threaded slider 302, the first direction and the second direction coincide with the first coordinate direction, and the first direction is a positive direction of the first coordinate direction, and the second moving direction is a negative direction of the first coordinate direction.
When the windshield glass plate is low, the driving assembly 400 outputs a clockwise driving force, the screw 301 of the driving assembly 400 receives the driving force and drives the threaded slider 302 to slide in the first direction, when the windshield support 200 is directly arranged on the threaded slider 302, the windshield support 200 moves in the first direction under the action of the threaded slider 302, and at the moment, the windshield support 200 rises in the first coordinate direction relative to the windshield base 100, which is equivalent to increasing the height of the windshield glass plate. When the windshield glass plate is high, the driving assembly 400 outputs a driving force in the counterclockwise direction, the screw 301 of the driving assembly 400 receives the driving force and drives the threaded slider 302 to slide in the second direction, and when the windshield support 200 is directly arranged on the threaded slider 302, the windshield support 200 moves in the second direction under the action of the threaded slider 302, and at the moment, the windshield support 200 descends in the first coordinate direction relative to the windshield base 100, which is equivalent to the reduction of the height of the windshield glass plate.
Or when the windshield glass plate is lower, the driving assembly 400 outputs a driving force in the counterclockwise direction, the screw 301 of the driving assembly 400 receives the driving force and drives the threaded slider 302 to slide in the first direction, when the windshield support 200 is directly arranged on the threaded slider 302, the windshield support 200 moves in the first direction under the action of the threaded slider 302, and at this time, the windshield support 200 rises in the first coordinate direction relative to the windshield base 100, which is equivalent to increasing the height of the windshield glass plate. When the windshield glass plate is higher, the driving assembly 400 outputs a clockwise driving force, the screw rod 301 of the driving assembly 400 receives the driving force and drives the threaded slider 302 to slide in the second direction, and when the windshield support 200 is directly arranged on the threaded slider 302, the windshield support 200 moves in the second direction under the action of the threaded slider 302, and at the moment, the windshield support 200 descends in the first coordinate direction relative to the windshield base 100, which is equivalent to the reduction of the height of the windshield glass plate.
When the wind shielding bracket 200 is directly fixed on the threaded slider 302, in order to ensure that the wind shielding bracket 200 stably ascends or descends, a sliding wheel and a guide rail groove matched with the sliding wheel are also arranged between the wind shielding bracket 200 and the wind shielding base 100, and when the sliding wheel is arranged on the wind shielding bracket 200, the guide rail groove is arranged on the wind shielding base 100; when the sliding wheels are disposed on the wind shielding base 100, the guide rail groove, the extending direction of which is the first coordinate direction, is disposed on the wind shielding bracket 200. And the guide rail grooves are arranged in pairs, at least one group is arranged, and when two groups are arranged, the two groups are symmetrically arranged to increase stability.

Specifically, the first transmission assembly 500 includes a hexagonal shaft 503, a first link 501 and a second link 502, wherein the hexagonal shaft 503 is rotatably disposed on the wind shielding base 100, and the hexagonal shaft 503 extends along a second coordinate direction, and the second coordinate direction is perpendicular to the first coordinate direction; the first end of the first connecting rod 501 is hinged to the threaded slider 302, the second end of the first connecting rod 501 is hinged to the first end of the second connecting rod 502, and the second end of the second connecting rod 502 is fixed to the hexagonal shaft 503 and drives the hexagonal shaft 503 to rotate.
The first link 501 and the second link 502 form a crank slider mechanism in cooperation with the threaded slider 302, and convert the reciprocating linear motion of the threaded slider 302 into a rotational motion of the hexagonal shaft 503. When the threaded slider 302 descends in the first coordinate direction, the first connecting rod 501 and the second connecting rod 502 drive the hexagonal shaft 503 to rotate anticlockwise; when the threaded slider 302 moves up in the first coordinate direction, the first link 501 and the second link 502 drive the hexagonal shaft 503 to rotate clockwise.
