Description

一种滑盖式隐藏激光雷达机械装置A sliding cover hidden lidar mechanical device

技术领域technical field

本实用新型涉及汽车技术领域,特别涉及一种滑盖式隐藏激光雷达机械装置。The utility model relates to the technical field of automobiles, in particular to a sliding cover type hidden laser radar mechanical device.

背景技术Background technique

当前新能源汽车的前视激光雷达一般都是固定式,即汽车前风挡上面凸起一个结构,将前视激光雷达放置于其中固定。这种固定式激光雷达结构非常影响整车外观的视觉效果,使得车辆科技含量不够强烈。At present, the forward-looking lidar of new energy vehicles is generally fixed, that is, a structure protrudes from the front windshield of the car, and the forward-looking lidar is placed in it and fixed. This fixed lidar structure greatly affects the visual effect of the vehicle's appearance, making the vehicle's technological content not strong enough.

市面上也存在另外一种升降式激光雷达的设计,但是该结构设计密封和固定都存在一定的缺陷。这种升降式激光雷达结构将雷达至于波纹管(一种密封膜)中实现密封,但是波纹管的耐久性和在极端天气暴露的环境下,易老化、脆裂,不利于密封,且该结构使用开放式托板结构对激光雷达进行固定,该开放式结构无密封可言。There is also another lifting lidar design on the market, but this structural design has certain defects in sealing and fixing. This lifting lidar structure seals the radar in the bellows (a kind of sealing film), but the durability of the bellows and the environment exposed to extreme weather are prone to aging and brittleness, which is not conducive to sealing, and the structure The lidar is fixed using an open pallet structure, which has no seal at all.

市面上还有另外一种隐藏式激光雷达是直接通过齿轮机构带动激光雷达直升直降的结构,但是该结构受造型影响较大,对整车的风阻和NVH影响较大,且直升直降的结构对于盖板的密封结构设计复杂且困难,且由于该结构齿轮结构直接作用于铰接的转轴位置,导致行程较小,且对驱动电机的输出功率和扭矩要求较大,不利于节能,对驱动电机的选型存在较大的挑战。There is another hidden lidar on the market that directly drives the lidar through the gear mechanism to go straight up and down. However, this structure is greatly affected by the shape and has a great impact on the wind resistance and NVH of the vehicle. The lower structure is complex and difficult to design the sealing structure of the cover plate, and because the gear structure of this structure directly acts on the position of the hinged shaft, the stroke is small, and the output power and torque of the driving motor are required to be large, which is not conducive to energy saving. There is a big challenge to the selection of the drive motor.
