Description
Technical Field
The utility model relates to an automotive filed especially relates to an on-vehicle camera scrubbing system.
Background
The vehicle-mounted camera mainly comprises an interior camera, a rear camera, a front camera, a side camera, a surrounding camera and the like. At present, cameras are mainly applied to backing images (rear view) and 360-degree panorama (round view) in a vehicle, more than 8 cameras equipped for various auxiliary devices of a high-end automobile are common, and the cameras are used for assisting drivers to park or trigger active safety functions such as emergency braking.
The smudgy types of the lens of the vehicle-mounted camera are mainly divided into two types according to the arrangement position of the camera, and the main smudgy types of the camera in the vehicle are dust, fingerprints, water stains, oil stains and the like; the main types of soiling of the cameras outside the vehicle are mud/dust/water stain/ice/unbroken rain.
Through the analysis, the dirty probability of occurrence of the camera in the vehicle is low, the user is easy to clean, and the camera outside the vehicle is more easy to be dirty due to the working environment, and the user is troublesome to clean along with the increase of the camera.
The main influence of the dirt on the camera at the present stage is that the user experience of auxiliary functions such as backing images and automatic parking is reduced or invalid, and the influence on the safety is small, so the requirement of the camera dirt removal at the present stage is not strong. With the popularization of ADAS and automatic driving, the pollution of the camera can influence the safety, so that the pollution removal of the camera outside the vehicle is imperative.
The dirtiness of on-vehicle camera needs can both be clear away at parking, driving in-process to need prevent that the camera surface from freezing, avoid the cleaning solution to freeze damage such as pipeline, water pump, air pump, arouse that the clean effect of camera reduces.
The prior art is used for driving the dirty mode of camera mainly is that injection rivers scrubbing and injection rivers + air-dry scrubbing two kinds of modes. Only the water jet is used for decontamination, and water alkali can be formed after wind blowing and sun drying, so that the surface coating of the camera objective lens can be separated after long-term use, and even the plastic objective lens is not transparent any more; in cold conditions, the sprayed water flow remains on the objective lens surface of the camera to be frozen, and the shot image is distorted. The intersection of the existing technical scheme that the dirt can be removed through water jet and air drying is near a water jet, residual water is easily formed in the water pipe after the jet is finished, and water scale is easily formed in the pipe. If the frost resistance of the glass water is poor, the glass water is leaked after the residual water in the water pipe and the water pump is frozen, and even the water pump is damaged and fails. Once leakage occurs on the waterway, the water pressure is insufficient, and the decontamination effect is influenced.
