Protecting and cleaning device used for solid-state laser radar and embedded into vehicle bodies and cleaning method

Abstract

The invention belongs to the technical field of vehicle-mounted sensors, and provides a protecting and cleaning device used for a solid-state laser radar and embedded into vehicle bodies and a cleaning method. The device comprises a linear motor, a windshield wiper, cleaning nozzles, a laser radar protective cover sleeve, a protective cover rotary motor, a laser radar base large platform, a laserradar protective cover, linear motor guide rails, a protective cover fixing plate and magnets. The device is suitable for the solid-state laser radar capable of being embedded into the vehicle bodies,the time when the laser radar cannot work in a stained state can be shortened, the working continuity of the sensor and the reliability of obtained data are guaranteed, solid stains are removed, thedevice is simple in structure, small in size, free of special auxiliary equipment, low in improvement degrees of the structures of fabricated vehicles, can be embedded into the vehicle bodies of mostof the vehicles, and is high in matching degree with vehicle body structures, and the integral shapes of the vehicles are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of vehicle sensors, in particular to a protective cleaning device and a cleaning method embedded in a vehicle body type solid-state laser radar. Background technique [0002] With the development of unmanned driving technology, more and more smart cars are beginning to use lidar sensors for the car's environmental perception. During the driving process, the lidar transmits environmental data to the car, and the on-board computing platform processes the data and sends driving instructions to the car in real time. Therefore, in order to ensure the safe and reliable driving of the car, the data of the lidar must be accurate and continuous. [0003] In addition, the current lidar can be roughly divided into mechanical lidar and solid-state lidar according to the principle. Mechanical LiDAR has a detection range of 360 degrees, but is too bulky and expensive to mass-produce. The detection range of solid-state ...

Problems solved by technology

This method is more efficient, but takes longer on stubborn stains and the lidar will also not work until the stain is done
