[0021] The utility model will be further described in connection with the drawings and specific embodiments:

[0022] As Figures 1 to 3 shown, the unmanned aerial vehicle airborne computer damping device based on the damping ball-floating rigid body structure provided by the utility model, including structural wall 1, NUC carrier 2, aluminum column 3, carbon fiber rigid body frame 4 and damping ball 5, carbon fiber rigid body frame 4 is located inside structural wall 1, the number of aluminum column 3 is four, one end of aluminum column 3 is connected with carbon fiber rigid body frame 4, the other end of aluminum column 3 is connected with unmanned aerial vehicle through screw, damping ball 5 is located between carbon fiber rigid body frame 4 and unmanned aerial vehicle. NUC carrier 2 is installed inside carbon fiber rigid body frame 4 and is fixed through screw, NUC carrier 2 is electrically connected with unmanned aerial vehicle.

[0023] The structural wall 1 is a cuboid column structure, the structural wall 1 is a hollow structure, the structural wall 1 is a supporting part, plays a supporting role, the section of the structural wall 1 is a mouth-shaped structure, the bottom of the structural wall 1 is in an open state and is fixedly connected with the unmanned aerial vehicle.

[0024] The aluminum column 3 is made of aluminum alloy, has the characteristics of light weight and high strength. The four aluminum columns 3 are respectively located at the four corners of the carbon fiber rigid frame 4, which can ensure the stable connection of the shock absorbing device mechanism and the unmanned aerial vehicle body.

[0025] The carbon fiber rigid frame 4 is a rectangular frame structure, the carbon fiber rigid frame 4 is formed by rigidly connecting carbon plates to form a stable frame structure for supporting and fixing the NUC carrier 2. The carbon fiber rigid frame 4 is a layered structure, and the NUC carrier 2 and the shock absorbing ball 5 are respectively layered in the carbon fiber rigid frame 4.

[0026] The carbon plate is made of carbon fiber material, and the carbon fiber material has the characteristics of high strength and light weight. It can effectively prevent the NUC carrier 2 from bending and deforming when impacted. In this embodiment, the NUC carrier 2 is a mature existing technology device, usually NUC12 or NUC13.

[0027] The number of shock absorbing balls 5 is two and arranged in parallel. The shock absorbing ball 5 is made of elastic material and is placed between the carbon fiber rigid frame 4 and the body of the unmanned aerial vehicle. The shape of the shock absorbing ball 5 is spherical, which can be elastically deformed when impacted to absorb impact energy and protect the NUC carrier 2 from damage. The NUC carrier 2 is installed inside the carbon fiber rigid frame 4 and fixed by screws to ensure its stability during flight. The main function of the NUC carrier 2 is to perform the computing task of the unmanned aerial vehicle. By fixing it inside the carbon fiber rigid frame 4, it can effectively prevent displacement or damage due to vibration or impact during flight.
