[0010] The advantages of this utility model are: This utility model is a mounting mechanism for a built-in airborne camera. Addressing the need for drone cameras to film airport runways and runway centerlines, a mounting mechanism is designed. This mechanism is installed under the nose of the drone, integrating the drone skin, camera mounting bracket, and aperture. The skin is connected to the drone structure via quick-release screws. The camera mounting bracket is installed inside the skin, serving to mount the camera and adjust its angle within a certain range. An aperture is located at the front of the bracket to facilitate camera filming of external scenes.

[0011] This utility model's installation mechanism integrates the drone skin, camera mounting bracket, and light window into a single unit. The camera is mounted on the bracket on the ground, the mounting angle is adjusted, and the camera plug is connected, completing the camera installation. The skin is then fixed to the drone structure, achieving overall installation. Installation is convenient and operation is simple.

[0012] The mounting mechanism of this utility model can be adjusted at different camera fields of view, making it highly adaptable and versatile.

[0013] The skin of the installation mechanism of this utility model is made of carbon fiber, the light window is made of acrylic glass, and the mounting bracket and the light window fixing plate are made of aluminum alloy. The material cost is low, which realizes low-cost manufacturing.

[0014] This invention mounts the camera inside the skin of the drone, having no impact on the aircraft's aerodynamics. Furthermore, the installation environment has minimal impact on the camera's performance, and the camera requires no structural reinforcement. The design is reasonable, achieves aircraft weight reduction, and has been verified through flight testing to meet usage requirements. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] Example 1. A built-in airborne camera mounting mechanism, see [link / reference]. Figure 1 and Figure 2The system includes a skin 1, with a mounting bracket 3 fixed to the inner side of the skin 1. A camera 2 is mounted on the mounting bracket 3. A light window 4 designed based on the shooting angle of the camera 2 is provided on the skin 1 in front of the mounting bracket 3. The mounting bracket 3 includes a bracket base 6 and an adjustment bracket 7. The camera 2 is mounted on the adjustment bracket 7. The bracket base 6 is fixed to the skin 1. The front end of the adjustment bracket 7 is hinged to the front end of the bracket base 6. The adjustment bracket 7 can rotate around the hinge point of the front end to adjust the shooting angle of the camera 2.
