The vehicle camera device is one of the widely used vehicle equipments. The rear end of the vehicle is equipped with a reversing camera device. During the reversing of the vehicle, the reversing camera device images are transmitted to the in-vehicle screen display to provide the driver to view the reversing distance and Whether it will collide with obstacles to avoid danger.

A lens that is generally installed on the outside of the vehicle. When rain or other water droplets may be sprayed on the surface of the lens, the image to be captured may be blurred or obscured. The driver cannot watch the vehicle while driving. Clear images can't accurately know whether the vehicle is safely separated from other people's things, thus increasing the probability of danger. Therefore, how to solve the problem that the outer lens of the vehicle is obscured by foreign objects and produces a blurred image is a problem that the relevant industry must consider.

In view of the above problems, the present invention provides an exterior lens cleaning system including an exterior lens, a vehicle signal input unit, a vehicle control module and a clearing device; the vehicle signal input unit receives at least one vehicle operation information transmitted from the outside, and the vehicle control module Connected to the vehicle signal input unit and received at least one vehicle operation information to generate a control signal, the cleaning device is electrically connected to the vehicle control module and corresponds to the exterior lens, and the cleaning device includes a fan, wherein the cleaning device receives the control signal, and Control the fan to run the air to the outside lens to remove foreign objects on the outside lens.

This creation uses the cleaning device to actively operate the air supply to the outside lens, and removes the foreign matter on the outer lens of the vehicle to apply to any vehicle equipped with the screen of the exterior image system. The outer lens of the vehicle has water droplets attached to the outside of the vehicle or after washing, or foreign matter adheres to the leaves. The active operation sensor or the driver can generate at least one vehicle operation information by using a directional light control switch, a gear shift switch or a corresponding water drop clear switch, and then generate a vehicle control information corresponding to the vehicle operation information.
