Background

Sensors are widely used in industry and in life, for example, in vehicle driving assistance systems and unmanned systems to detect the environment around a vehicle and identify surrounding objects. Sensor types include laser radar, cameras, and the like.

However, the surfaces of the sensors such as the camera and the laser radar are easily affected by the environment, various pollutants, rain, snow, dust, stains, insect corpses and the like can be attached to the surfaces of the sensors, and the surfaces of the sensors are polluted to influence the acquisition effect: for example, when a camera is attached by rain, a lens becomes blurred, and an image may be distorted, so that all images collected under normal conditions cannot be collected; if dust and dirt exist on the surface of the laser radar, the emission and the reception of laser are shielded to generate missed detection and false detection of obstacles. Once the sensor is contaminated, the driving assistance function may be limited and the automatic driving function may be disabled, thereby causing a traffic accident.

Therefore, the sensor requires a cleaning device. The existing sensor cleaning device generally adopts a scraping cleaning mode that a windscreen wiper moves and a sensor is fixed, and the scraping mode comprises a translation scraping mode and a rotary scraping mode.

With the rotary scraping, the related structure of the rotary scraping strip is complicated, and the scraping strip is also required to be in direct contact with the sensor surface, so that the sensor surface is abraded. Furthermore, more serious are: when the scraping strip moves and scrapes on the surface of the sensor, the sensor can be interfered to work, faults which are identified by mistake can be caused, and a vehicle driving auxiliary system or an unmanned driving system is influenced.
