The invention belongs to the technical field of auxiliary equipment of vehicle signal devices, and particularly relates to a protection device for distance measurement of a large transport vehicle. The protection device comprises a dustproof shell, an open-close type lens cover mechanism and a fixed installation mechanism, the lens cover mechanism comprises a first motor, a large gear and a small gear, the large gear and the small gear are meshed, a light hole corresponding to a lens window hole is formed in the middle of the large gear, and when the large gear rotates positively and negatively, the ends, corresponding to the light hole, of four sliding blocks are closed or separated; the opening and closing of the maximum circular area can be realized in a very small space, the light hole can be shielded or opened, when distance measurement is not needed, the light hole can be shielded, dust can be effectively prevented from being attached to the optical lens, the interference of the dust on the optical path is reduced, and the precision and the stability of the distance measurement device are improved; the fixed installation mechanism can achieve clamping installation or magnetic type installation of the protection device, and when installation is completed, the position of an L-shaped clamping plate is adjusted, and the horizontal distance or the vertical distance of the laser type distance measuring device when the laser type distance measuring device passes through an obstacle can be adjusted.

    本发明属于车辆信号装置辅助设备的技术领域,具体涉及一种用于大型运输车测距的保护装置。包括防尘外壳、开合式镜盖机构和固定安装机构,镜盖机构包括第一电机、相啮合的大齿轮和小齿轮,大齿轮的中部对应镜头视窗孔开设有透光孔,大齿轮正、反转时,四块滑块对应透光孔一端对合或分开,能够在极小的空间内实现最大圆形区域的开闭,可使得透光孔遮蔽或敞开,不需要测距时,可使透光孔遮蔽,能有效避免灰尘在光学镜片上的附着,降低灰尘对光路的干扰,提高测距装置的精度和稳定性;固定安装机构可实现保护装置的夹紧安装或是磁吸式安装,当安装完成时,调节L形夹板的位置,可以调整激光式测距装置侧的通过障碍物时的水平距离或是垂直距离。
