[0002] LiDAR is a high-precision sensor that is mainly used to measure information such as the distance, direction, height, speed, and shape of an object. The power board of the LiDAR is an indispensable part of the LiDAR system. It is responsible for providing stable and reliable power supply and drive control for the LiDAR to ensure that the LiDAR can work normally.
[0003] The existing structure of the laser radar is a large-area power supply board, which is fixed on the rotating bearing of the radar. This structure creates a certain distance between the power supply board and the base plate. Therefore, the transmitting tube fixed on the power supply board and the receiving tube fixed on the base plate are far apart. That is, the optical communication path for sending data is long, which makes the signal weaker, making it easy to generate bit errors, and the communication rate is also low, which in turn affects the use effect of the laser radar.

[0008] Preferably, the surface of the power board is electrically connected to a Pin terminal and the other end of the Pin terminal is electrically connected to a transmitting and receiving module board, so that power supply and information communication are performed between the power board and the transmitting and receiving module board through the Pin terminal.
[0009] Preferably, a lens module bracket is connected to the surface of the transmitting and receiving module board, and one end of the lens module bracket is connected to a lens barrel.
[0010] Preferably, the surface of the base is connected to a mounting bracket, and a motor is connected inside the mounting bracket, and the output shaft of the motor is connected to a drive disk.
[0011] Preferably, the driving disc is connected to the rotating disc via a flexible transmission.
[0012] Compared with the prior art, the beneficial effects of the present invention are: by adjusting the internal structure of the radar, reducing the volume of the power board, changing the position of the power board, and installing the power board in the middle of the bearing, the radar main control structure is compact and the space utilization rate is high. The power board, transmitting tube, and receiving tube are integrated and installed in the installation inner tube, which improves the space utilization rate and facilitates compact installation in the laser radar system. The distance between the transmitting tube fixed on the power board and the receiving tube fixed on the base plate is reduced, that is, the optical communication path is shortened, thereby improving the intensity of the optical signal and the communication rate.
