Abstract

The invention provides a heating device for a radar housing. The device comprises a bottom plate which is transparent and can enable laser to pass through, at least two electric heating elements whichare arranged on the bottom plate in a non-intersecting manner and are used for emitting heat when being electrified, and at least two connecting pieces which are arranged on the bottom plate, are transparent, allow the laser to pass through and are used for connecting the at least two electric heating elements in parallel. The at least two connecting pieces are suitable for being connected with an external power supply so as to supply power to the at least two electric heating elements which are connected in parallel. The invention further provides a manufacturing method of the radar housingand the heating device. Barrier-free heating of the vehicle-mounted radar laser can be realized, so that water or ice on the surface of the radar housing can be removed.

Description

technical field [0001] The present application relates to the field of vehicle radar, in particular to a heating device for a vehicle radar housing. Background technique [0002] At present, the lidar is usually installed on the top of the vehicle. When the vehicle starts or encounters extreme weather, there will be water mist or even frost on the lidar housing. If the water mist or frost on the radar cover cannot be removed quickly and effectively, It will make the lidar function temporarily abnormal, making the vehicle unable to travel or posing safety hazards when traveling. [0003] Since the mechanical lidar needs a 360° rotation, if heating components are placed on the lidar, it will block the projection of the radar laser, which will affect the reliability of the lidar. The solid-state lidar housing (generally arc-shaped) needs to ensure a certain viewing angle. When installing the heating component, the size of the outer cover is often increased to ensure the viewin...
