AI Technical Summary

Technical Problem

The existing mechanical lidar has a long shaft length, which houses the drive device, communication device and power supply device on the base, resulting in an increase in the size of the lidar.

Method used

A hollow cavity is defined by a hollow fixed shaft and a rotating part. The drive unit, power supply module and communication unit are set in the hollow cavity, omitting the solid shaft and reducing the axial dimension of the lidar along the fixed shaft.

Benefits of technology

This effectively reduces the size and height of the lidar.

Abstract

A laser radar, characterized in comprising: a base (200) comprising a fixed shaft (210), the fixed shaft (210) being a hollow shaft; a rotating part (100) rotationally connected with the base (200) and configured to rotate around a central axis of the fixed shaft (210), the rotating part (100) and the fixed shaft (210) jointly defining a hollow chamber, and a laser transceiver system of the laser radar being fixed to the rotating part (100); and a driving device for driving the rotating part (100) to rotate relative to the base (200), the driving device comprising a stator (241) and a rotor (242) coupled with the stator (241), the stator (241) being sleeved on an outer peripheral wall of the fixed shaft (210), the rotor (242) being arranged around the stator (241), and the rotor (242) being connected with the rotating part (100). The driving device, a power supply part and a communication part of the laser radar can not be arranged on the same shaft body, so that the axial dimension of the laser radar along the fixed shaft can be reduced, and the volume of the laser radar is further reduced.
