Description

A SLR camera damping device for fixed-wing unmanned aerial vehicles

technical field

The utility model relates to the field of aerial photography of unmanned aerial vehicles, in particular to a shock absorbing device for a single-lens reflex camera used on a fixed-wing unmanned aerial vehicle.

Background technique

SLR cameras are the mainstream acquisition equipment for drones to obtain higher-resolution ground images and higher-precision data mapping. Originally, SLR cameras were designed for handheld shooting and tripod fixed shooting, and their working environment is a vibration-free environment. However, when an oil-powered UAV is used as an aerial photography device, the vibration environment inside the fuselage far exceeds the vibration that it is designed to accept. If the camera is not protected and the vibration is isolated, the aerial photo will be blurred and deformed. If it is heavy, it will directly damage the camera and cause great losses.

At present, many fixed-wing UAVs achieve camera shock absorption in the following way: just use a single sponge or soft material to wrap the camera for shock absorption, the shock absorption effect is not good, because a large area of sponge is in contact with the drone body , the vibration is also transmitted to the camera due to the large contact area, and the more vibration is transmitted to the camera, the effect of effective vibration reduction cannot be achieved. At the same time, it can't effectively absorb the momentary vibration when the drone lands (the g value of the acceleration of gravity is about: 0.5g value-0.8g value).

The beneficial effects of the utility model are: the shock absorber and the UAV fuselage adopt the minimum contact surface, which can isolate the vibration from the UAV to the greatest extent, and can absorb the instantaneous vibration generated when the UAV lands and lands (can absorb the maximum 4g value), and firmly fix the camera equipment on the drone body to avoid impact.

On the basis of the above-mentioned technical scheme, the utility model can also be further improved as follows:

Further, the primary shock-absorbing disk is a frame plate structure; the secondary shock-absorbing disk includes a chassis and a stopper that match the frame-plate structure of the primary shock-absorbing disk, and the stopper is installed vertically upward On both sides of the chassis, the fixing frame is located on the upper part between the blocks, and the primary vertical shock absorber is arranged between the chassis and the primary shock absorber.

The beneficial effect of adopting the above-mentioned further technical solution is: on the one hand, the first-stage shock-absorbing disk and the second-stage shock-absorbing disk of the frame-mounted structure reduce the contact surface with the UAV fuselage; load.

Further, the secondary transverse arm shock absorber is located between the stopper and the side wall of the fixing frame.

Further, the primary vertical shock absorber includes a fixing seat, a screw and a rubber disk, the rubber disk axially passes through the fixing seat, and the screw passes through the rubber disk to connect the secondary shock absorber.
