Abstract

The invention provides a vehicle radar laser scanning mechanism and a manufacturing method of the vehicle radar laser scanning mechanism. The vehicle radar laser scanning mechanism comprises a motor and a lens bracket matched with an output shaft of the motor in a transmission mode. An emitting lens and a receiving lens are arranged in the lens bracket in parallel. A casing of the motor is fixedly connected with a bottom plate through a motor base, the output shaft of the motor is fixedly connected with the middle of a driving wheel, the end of the driving wheel is matched with one end of a connecting rod in a rotating mode, the other end of the connecting rod is matched with one end of an oscillating rod in a rotating mode, the other end of the oscillating rod is matched with the bottom plate in a rotating mode through a fixed rotating shaft and a fixed rotating shaft bearing sequentially, the fixed rotating shaft bearing is arranged at the bottom of the fixed rotating shaft, an encoder is arranged in the middle of the fixed rotating shaft, and the top of the fixed rotating shaft is fixedly connected with the bottom of the lens bracket through the oscillating rod. The vehicle radar laser scanning mechanism is high in scanning efficiency, good in stability, high in scanning precision and high in controllability.

Description

technical field [0001] The invention relates to a vehicle laser radar, in particular to a vehicle radar laser scanning mechanism and a manufacturing method thereof, which are particularly suitable for improving the radar lateral detection accuracy and scanning efficiency. Background technique [0002] LiDAR can accurately measure the position, motion state and shape of the target, detect, identify, distinguish and track the target. With the increasing application research of lidar, lidar has become a kind of system with multiple functions. At present, the application demand of lidar in the automotive field is increasing, especially in the field of active safety control, the most typical of which is to detect obstacles ahead. In order to detect obstacles in a timely and effective manner and ensure driving safety, lidar must reach a certain horizontal detection range, and has the characteristics of high resolution and high detection accuracy. [0003] The Chinese patent appl...
