Device for automatically removing rainwater from rearview mirror outside vehicle

Abstract

The invention provides a device for automatically removing rainwater from a rearview mirror outside a vehicle, and belongs to the field of automobile parts. The device for automatically removing the rainwater from the rearview mirror outside the vehicle comprises a water storage cup, a water level sensor, a controller and heating devices, wherein the water storage cup is used for collecting rainwater within a predetermined period of time, a drainage pipeline is connected to the cup bottom of the water storage cup, and a leak-off valve is arranged on the drainage pipeline; the water level sensor is used for detecting the volume of rainwater collected by the water storage cup and sending a detection signal indicating the volume; the controller is used for receiving a detection signal to acquire the volume, calculating real-time rainfall capacity within a predetermined time period according to the volume, and controlling at least a part of a plurality of heating devices installed on the rearview mirror to work according to the magnitude of the real-time rainfall capacity; and the heating devices are used for heating the rearview mirror to remove the rainwater from the rearview mirror.The device for automatically removing the rainwater from the rearview mirror outside the vehicle controls the heating degree of the heating devices to a rearview mirror lens according to the rainfallcapacity, and has a simple structure and high practicability.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a device for automatically removing rainwater from a vehicle exterior rearview mirror. Background technique [0002] The rearview mirror is a tool for the driver to directly obtain external information such as the rear, side and bottom while sitting in the driver's seat. Reasonable use of the external information fed back by the rearview mirror can facilitate the driver's operation, prevent driving safety accidents, and ensure personal safety . [0003] The rearview mirror is installed on the outer side of the car body. When the vehicle is driving, it is used to observe the road conditions behind. In sunny days, the rearview mirror can clearly reflect the rear situation, but in rainy days, the rearview mirror lens will Adhering to rainwater, it cannot clearly reflect the rear situation, which seriously affects driving safety and is dangerous to the driver. At present, some r...

[0003] The rearview mirror is installed on the outer side of the car body. When the vehicle is driving, it is used to observe the road conditions behind. In sunny days, the rearview mirror can clearly reflect the rear situation, but in rainy days, the rearview mirror lens will Attached to the rainwater, it cannot clearly reflect the situation behind, which seriously affects the driving safety and is dangerous to the driver

At present, some rearview mirrors that can prevent water droplets from adhering to the lens have also appeared on the market, but they are expensive and generally only suitable for high-end cars, and the internal structure is complicated, energy consumption, practicability and versatility are not high.
