Description

Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicles, in particular to a structure of an unmanned aerial vehicle used for forestry exploration. Background Art

[0002] A drone is an unmanned aircraft that is controlled by a radio remote control device and a self-contained program control device. Drones are actually a general term for unmanned aerial vehicles. From a technical point of view, they can be divided into several categories: unmanned helicopters, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airships, and unmanned paragliders.

[0003] The application of drones is particularly extensive, and they are also used in the process of forestry exploration. The Chinese patent with the announcement number CN215554135U currently discloses a drone for forestry exploration, including a drone, a laser radar sensor, a camera and a platform end. A connecting rod is connected to the lower side of the drone, and the connecting rod fixes the laser radar sensor through a first locking member and fixes the camera through a second locking member. However, when the drone in the above patent falls after the exploration is completed, it is difficult to buffer the collision between the drone and the ground when the drone falls, which easily causes the laser radar sensor and the camera of the drone to be damaged by vibration, thereby affecting the use of the exploration components. For this reason, we propose a drone structure used in forestry exploration to solve the above problems. Utility Model Content
