Problems solved by technology
[0018] The invention provides a low-cost shock-absorbing structure for the photoelectric load equipment of the UAV. By integrating the power supply battery of the UAV and the load, the shock-absorbing rubber ball is installed at an angle to the horizontal plane and the shock-absorbing spring and rubber shock absorber The shock balls are installed in series, etc., on the basis of reducing the natural frequency of the photoelectric load, it improves the shock isolation effect on the full-frequency vibration of the load, and can solve the problem of increasing the counterweight to reduce the flight time of the UAV in the existing technology, and the design of the shock absorbing structure is complicated. The problem of poor adaptability to the environment

Embodiment 1
[0048] Such as figure 1 , 2 , 3(A), and 3(B), the mounting plate 5 used in this embodiment is rectangular, and 4 sets of damping members are used, which are arranged on the four corners of the square, and the photoelectric imaging load is installed through the support column 7 Below the mounting plate 5, it can be threaded or welded.
[0049] Use magic straps to pass through the two long circular grooves of the mounting plate 5, and fix the battery 6, and the four support columns 7 pass through the four light holes distributed in the center of the mounting plate 5 to hoist and fix the photoelectric imaging load. The included angle of rubber damping ball 4 and horizontal plane is chosen 45 °.

The invention discloses a shock-absorbing structure for an unmanned aerial vehicle, which includes several sets of shock-absorbing components, mounting plates and batteries, and each set of shock-absorbing components is composed of a spring I, a spring II, a support rod, a sleeve and rubber for shock absorption. ball composition. The invention can solve the problems in the prior art that increasing the counterweight reduces the flight time of the unmanned aerial vehicle, complicating the design of the shock-absorbing structure and having poor wide adaptability to the environment.
Description
technical field [0001] The invention relates to the technical field of mechanical design, in particular to a shock-absorbing structure of an unmanned aerial vehicle, in particular to a shock-absorbing structure of an unmanned aerial vehicle photoelectric imaging load. Background technique [0002] A multi-rotor UAV is an unmanned aerial vehicle with three or more rotor shafts. The multi-rotor UAV has the advantages of small size, light weight, hoverability, and convenient manipulation. In recent years, it has developed rapidly in the field of aerial photography. In order to prolong the working time of multi-rotor drones in the air, under the same video imaging quality, using lighter and smaller loads has become the first choice of drone manufacturers. . However, when multiple propellers work at the same time, it will bring high-frequency vibration to the body of the multi-rotor UAV, and the vibration will be transmitted to the photoelectric imaging load carried by the body,...
