The embodiment of the invention relates to the technical field of unmanned driving, and particularly discloses an unmanned vehicle with a liftable laser radar, wherein the unmanned vehicle comprises a vehicle body, a laser radar and a lifting device; the vehicle roof of the vehicle body is provided with a containing groove and a sliding hole communicated with the containing groove, and the sliding hole is located at the groove bottom of the containing groove; the laser radar comprises a transparent shell and a radar body; the radar body is contained in the transparent shell, the transparent shell is contained in the containing groove, and the transparent shell can do reciprocating motion in the containing groove; the lifting device comprises a lead screw, a sleeving assembly, a lifting bearing and a driving mechanism, the lifting bearing is fixed to the surface, facing the groove bottom of the containing groove, of the transparent shell, the lifting bearing sleeves one end of the lead screw, the other end of the lead screw is contained in the sliding hole, the sleeving assembly sleeves the lead screw and is in threaded connection with the lead screw, and the driving mechanism is connected with the sleeving assembly; when the sleeving assembly rotates, the lead screw pushes the transparent shell to reciprocate along the central axis of the containing groove. In this way, dust deposition on the laser radar can be avoided.
本发明实施例涉及无人驾驶技术领域,具体公开了一种激光雷达可升降的无人车,包括车体,车体的车顶设置有收容槽和与收容槽连通的滑孔,滑孔位于收容槽的槽底;激光雷达,包括透明壳体和雷达本体,雷达本体收容于透明壳体内,透明壳体收容于收容槽,并且透明壳体可在收容槽内做往复运动;升降装置,包括丝杆、套接组件、升降轴承和驱动机构,升降轴承固定于透明壳体面向收容槽的槽底的一表面,并且升降轴承套接于丝杆的一端,丝杆的另一端收容于滑孔,套接组件套接于丝杆并螺接,驱动机构与套接组件连接,在套接组件转动时,丝杆推动透明壳体沿收容槽的中轴线往复运动。通过上述方式,本发明实施例能够避免激光雷达沉积灰尘。
