Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and in particular to a camera fixing structure for unmanned aerial vehicles. Background Art

[0002] Drones have extremely wide applications in many fields. If a natural disaster or dangerous situation occurs, drones can also be used for rapid monitoring. When using a drone, it is generally necessary to assemble the drone before it can be released. In rescue operations, due to time constraints, using a screwdriver to assemble or replace parts such as cameras is cumbersome and wastes rescue time.

[0003] However, current drones are often connected to cameras via screws, which will delay time and be cumbersome to operate in the event of an emergency. Therefore, a drone camera fixing structure that can be quickly disassembled and assembled is proposed to facilitate quick installation and fixing of the camera.

[0004] A camera fixing structure for a geological survey UAV is disclosed in announcement number CN220076694U. Although the utility model discloses a camera fixing structure for a geological survey UAV, including a mounting seat, a camera on the mounting seat, a slider on the camera, a splint on the slider, a moving mechanism installed on the splint, a driving mechanism installed on the splint, the moving mechanism is used to adjust the position of the driving mechanism, and a cleaning mechanism is installed on the driving mechanism to facilitate wet cleaning of the camera and drying of the camera to avoid dust or fog adhering to the surface of the camera and improve the clarity of image acquisition.

[0005] Although the above patent achieves the goal of wiping and cleaning the dust and fog on the surface of the camera through a cleaning mechanism, preventing dust or fog from adhering to the surface of the camera and affecting image acquisition, thereby improving the clarity of the image acquisition process and improving image acquisition efficiency; however, the device lacks the setting of quick disassembly components and limiting mechanisms. In the event of a dangerous situation, assembling the camera will delay time and the operation is also relatively cumbersome.

[0006] Therefore, it is necessary to invent a drone camera fixing structure to solve the above problems. Utility Model Content
