For the above-mentioned wiper, since the wind turbine is fixed on the housing of the rearview mirror, when the vehicle is running, it will generate wind force, and the wind turbine will rotate under the action of the wind force, and then the power can be transmitted to the annular wiper blade through the transmission mechanism , so that the ring-shaped wiper blade slides reciprocally along the sheathing direction of the lens, and then the lens of the rearview mirror can be clear in rainy weather, ensuring the safety of the vehicle in rainy weather.

It should be noted that when the rearview mirror is arranged on the vehicle in the horizontal direction, the annular wiper blade slides in the horizontal direction; when the rearview mirror is arranged in the vertical direction on the vehicle, the annular wiper blade slides in the vertical direction In addition, it should be noted that the size of the blades of the wind turbine can be changed according to actual needs to meet the needs of higher power, and the size changes include blade height, blade rotation radius, and blade swept area.

In some specific embodiments, the above-mentioned transmission mechanism 4 may specifically include a connecting rod 41, a rocker 42 and a transmission shaft 43. One end of the connecting rod 41 is hinged to the part of the ring-shaped wiper blade 2 located at the back of the lens 1. The connecting rod 41 The other end of the rocker 42 is hinged with one end of the rocking bar 42, and the other end of the rocking bar 42 is vertically fixed on the transmission shaft 43, and the transmission shaft 43 is connected in transmission with the output shaft 31 of the wind turbine 3. It should be noted that the size of the rocker and connecting rod needs to be changed according to the size of the rearview mirror. These two are the main factors affecting the stroke length of the wiper blade. It should be ensured that the ring-shaped wiper blade has as long as possible. work plan. Of course, it can be understood that the above-mentioned link mechanism is only a preferred example of the transmission mechanism of the embodiment of the present invention.
