technical field

The utility model relates to the technical field of wipers, in particular to a variable section wiper device for vehicles.

Background technique

Wipers, also known as wipers, water dials, wipers or windshield wipers, are devices used to wipe off raindrops and dust attached to the windshield of vehicles to improve the visibility of drivers and increase driving safety. Cars almost everywhere have windshield wipers because they are required by law. Vehicles such as hatchbacks and recreational vehicles also have wipers on the rear windows. In addition to cars, other means of transportation are also equipped with wipers, such as trains and trams. Some engineering tools, such as cranes, are also equipped with wipers. The power source of the wipers comes from the electric motor, which is the core of the entire wiper system. The quality requirements for wiper motors are quite high. It uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is generally integrated with the mechanical part of the worm gear. The effect of the worm and gear mechanism is to reduce the speed and increase the twist. Its output shaft drives the four-bar linkage, and the continuous rotational motion is changed into a left-right swinging motion through the four-bar linkage.

The wiper area of the traditional vehicle wiper is fixed, and there are dead angles, which affect the driver's operating vision. Therefore, we propose a variable section wiper device for vehicles.
