Abstract

The invention provides a lens assembly, a lens module, a laser module and a laser radar device. The lens assembly comprises a lens fixing seat and a lens. The lens fixing seat is provided with an accommodating hole. And the lens is arranged in the accommodating hole of the lens fixing seat. The optical axis of the lens and the central symmetry axis of the outer wall face of the lens fixing base are parallel to each other and spaced by a preset distance. According to the invention, the central symmetry axis of the lens fixing seat and the central symmetry axis of the lens are parallel to each other and are spaced by the preset distance, so that when the lens assembly is applied to the laser radar device of the sweeping robot, the light emitted by the laser assembly can be deflected by a certain angle, and the actual application requirement of the laser radar device is met.

Description

technical field [0001] The invention belongs to the field of laser technology, and in particular relates to a lens assembly, a lens module, a laser module and a laser radar device. Background technique [0002] In 2009, Neato released a laser radar for robots. The laser radar uses the triangular ranging method between the laser transmitter and receiver to measure the distance to obstacles. The laser ranging sensor is installed on the motor. , measure the distance within a 360° circle by rotating, and draw an indoor map based on this. The laser transmitter is one of the core components of lidar. In conventional application scenarios, in order to adjust the focal length of the laser emitter, and then adjust the position and shape of the projection spot generated by the laser emitter to meet the standard, the laser emitter is usually set in a two-stage structure. The optical lens is located in one section, and the laser assembly is located in the other section. The two-sectio...
