Description

Technical Field

[0001] This utility model belongs to the field of lidar technology, specifically, it relates to a protection device for lidar. Background Art

[0002] As a light detection and ranging device, lidar works by emitting a detection signal (laser beam) towards the target, then comparing the received signal reflected back from the target (target echo) with the emitted signal. After appropriate processing, relevant information about the target can be obtained. Due to its small size and light weight, lidar is increasingly widely used. As a high-precision detection device, the normal operation of lidar is crucial to ensuring the safety and accuracy of the system. Therefore, necessary protection is required for lidar, necessitating the use of lidar protection devices. Application number CN202122210916.8 discloses a protection device for lidar, which, by setting up a protective shell, a top cover, and a lifting mechanism, allows the lidar body to be lowered into the protective shell when not in use, thus protecting the lidar. However, the opening and closing assembly of the top cover and the protective shell, as well as the lifting operation of the lifting mechanism, are all manually adjusted. When the lidar is installed in a high position, opening the top cover and adjusting the lifting mechanism are inconvenient, resulting in poor overall effectiveness of the protection device.

[0003] In view of this, the present utility model is proposed. Utility Model Content
