Description

Technical Field

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

[0002] A drone is an unmanned aircraft controlled by a radio remote control device or an onboard computer program control system. It has a simple structure and low cost. Drone aerial photography is becoming more and more popular because of its large shooting field of view, small shooting angle constraints, and good light, field of view, and angle of the photos taken. Therefore, the camera is installed on the drone through a clamping device. There are at least the following disadvantages in the use of the existing clamping device: 1. The existing clamping device has a poor clamping effect on the camera when in use, and is not convenient for clamping drone cameras of different sizes, which reduces the scope of application and reduces practicality; 2. Due to the vibration generated by the drone flight, the camera will shake slightly, making the camera easily damaged by the vibration, and also affecting the quality of the camera's shooting picture. Therefore, we introduce a clamping device for drone cameras. Utility Model Content

[0024] In this embodiment, the shock-absorbing mechanism 3 includes a shock-absorbing box 31. A shock-absorbing frame 32 is inserted and movably connected to the middle of the upper box wall of the shock-absorbing box 31, and the upper end of the shock-absorbing frame 32 is fixedly connected to the lower end of the mounting plate 1.

Then, the clamped and installed camera body 11 can be installed on the drone through the mounting hole 2 on the mounting plate 1. When the drone drives the camera body 11 to fly and shoot, the vibration pushes the shock-absorbing frame 32 to move in the shock-absorbing box 31, which can reduce the vibration of the drone. Then, through the elasticity of several shock-absorbing springs 33 and the suppression of the elasticity of the shock-absorbing springs 33 by four shock absorbers 4, the shock-absorbing effect of the vibration can be enhanced. Then, through the magnetic repulsion force generated between the first magnetic strip 34 and the second magnetic strip 35, the shock-absorbing effect of the camera body 11 can be further enhanced, so that the camera body 11 is not easily damaged by vibration, thereby extending the service life of the camera body 11 and ensuring the quality of the pictures taken by the camera body 11.
