Concealed laser radar

Abstract

The invention relates to the technical field of vehicle engineering, and discloses a concealed laser radar, which comprises a sealing box, the surface of which is provided with a window, and the sealing box is also provided with a drainage pipe for drainage; the detection radar is rotationally mounted in the sealing box, and a cover plate is arranged at the top of the detection radar; and the driving mechanism is mounted on the sealing box. The device has the following advantages and effects that the detection radar is raised or lowered through rotation of the rotating shaft, the movement range of the detection radar is reduced, meanwhile, the cover plate is used for shielding, a corrugated pipe or a sealing film which is prone to damage and difficult to control is not needed, a sealing box with good sealing performance can be used as a mounting foundation, and the sealing effect is good. And the possibility that water enters the vehicle from the installation position of the laser radar is reduced. And meanwhile, when the laser radar does not need to be used, the detection radar can be put down, so that the whole laser radar and the vehicle are integrated, and the visual effect is better.

Description

technical field [0001] The present application relates to the technical field of vehicle engineering, in particular to a concealed lidar. Background technique [0002] Lidar is a device that measures the distance, speed and other parameters of the target object by sending a laser to the surface of the object, and then measuring the arrival time of the reflected beam. All-in-one optical instrument. In the autonomous driving technology, the environmental perception system is a basic and crucial part, which is the guarantee of the safety and intelligence of the autonomous vehicle. Among the environmental perception sensors, the lidar has the advantages of reliability, detection range and ranging accuracy. Has incomparable advantages. With the development of technologies such as autonomous driving, there are more and more scenarios in which lidars are integrated and installed in vehicles. [0003] At present, the current forward-looking lidars of new energy vehicles are gener...

Problems solved by technology

[0003] At present, the current front-looking lidar of new energy vehicles is generally fixed, that is, a structure protrudes from the front windshield of the car, and the front-looking lidar is placed in it to fix it, which greatly affects the appearance of the whole vehicle and makes buyers feel uncomfortable. , has a certain impact on product sales, and at the same time, it will increase the wind resistance when driving, affect the driving experience, and also generate noise when driving at high speed

[0004] There is also another lifting lidar design on the market, which uses some structures to lift the entire lidar directly. This is called the lifting lidar, but there are certain defects in the sealing and fixing of the structural design

For example, due to the large range of movement of this type of structure, a sealing method with strong ductility is required, such as placing the radar in a bellows or a sealing film to achieve sealing, but the durability of these two structures is insufficient. , easy to age, brittle, not conducive to sealing, and repeated folding of the bellows or sealing film will also cause damage to the sealing material

And considering the folding of the bellows and the sealing film, as well as the large range of radar lifting activities, it is also necessary to use an open pallet structure as the base for the lidar installation. The open pallet is mainly for the wiring harness and connection of the laser radar. Due to the movement of structures such as devices or pipelines, a considerable number of openings are set, so it is called an open pallet. The sealing effect between the open pallet and the vehicle sheet metal is poor, and it is easy to appear from the laser radar. If water leaks into the car
