Product structure for automatically removing frost on surface of laser radar window through sealed heating

Abstract

The invention discloses a product structure for automatically removing frost on the surface of a laser radar window through sealed heating in the technical field of electric vehicles. The product structure comprises a laser radar cover and an assembly shell, motor bodies are symmetrically installed on the two sides of the laser radar cover, connecting pieces are fixedly connected with the output ends of the motor bodies, gear push rods are fixedly connected with the connecting pieces, the end, away from the corresponding motor body, of each gear push rod is fixedly connected with a transmission rod, the end, away from the corresponding motor body, of each transmission rod is fixedly connected with a lower cover, a carbon fiber heating wire is fixedly installed on each lower cover, the periphery of the side, close to the corresponding carbon fiber heating wire, of each lower cover is coated with hot melt adhesive, the side, away from the corresponding lower cover, of the hot melt adhesive is fixedly connected with an upper cover. Carbon fiber is used for heating, the purpose of rapidly heating to the required temperature with low energy consumption can be well achieved, and heat loss in the heating process is avoided through sealed heating of the surface of the laser radar cover.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a product structure for automatically removing frost on the surface of a lidar window through sealing and heating. Background technique [0002] With the rapid development of electric vehicles, millimeter-wave radar measurement technology cannot be widely used in the L3 stage due to the limitation of its own measurement distance and accuracy in the L3 stage of autonomous driving. Lidar can measure centimeters within a range of 350m. The degree has become a must-have automotive measuring device. The main factor affecting the lidar dome measurement is the frost on the surface of the lidar. At this stage, there is no case of using heating wire to remove frost on the surface of the radome and actual mass production. Limited to the arrangement of heating wires, the surface of the lidar cover cannot be removed cleanly, resulting in distortion of transmission and reception. ...

[0003] There are few cases of mass production of LiDAR dome products with heating and frost removal in the market. The heating method mainly uses heating wire and ITO to heat the surface of the product, which cannot remove the frost on the inner edge of the LiDAR dome window area well.

In addition, in the extreme environment of -40 degrees, the ice and frost on the edge of the laser radome combined with the heating wire can be removed, but the surrounding area that cannot be heated forms a hollow state relative to the product surface, which affects the measurement and analysis of the laser radome, forming Security risks
