Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an image acquisition device for unmanned aerial vehicles. Background Art

[0002] Unmanned aerial vehicles, also known as drones, are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. They have no cockpit but are equipped with autopilots, program control devices and other equipment. Personnel on the ground, on ships or at the mother aircraft remote control station use radar and other equipment to track, locate, remotely control, telemeter and digitally transmit them. By combining image acquisition devices with drones, images can be acquired in the air.

[0003] Publication No. CN211468810U discloses a drone image acquisition device. The patent is convenient and quick to connect the drone through a fastening nut, and is applicable to a wide range of models. The rubber pad can prevent the fastening nut from loosening due to flight turbulence. The second servo motor drives the camera body to rotate horizontally, and the first servo motor drives the camera body to rotate longitudinally. The shooting angle of the camera body can be flexibly adjusted. The transparent cover has excellent protection, reduces the impact of the external environment, and extends the service life of the device. When there is a lot of dust or rainy days, the third servo motor drives the driven gear and the second shaft to rotate forward and reversely, so that the arc rod reciprocates along the transparent cover. The transparent cover is cleaned by brush hairs, which improves the shooting quality and can be used on rainy days. The ceramic heating plate can heat to prevent the transparent cover from freezing and condensing. The device has a simple structure and is easy to process. However, the patent still has the following problems in actual use:

[0004] The third servo motor drives the driven gear and the second rotating shaft to rotate forward and reversely, so that the arc rod reciprocates along the transparent cover, and the transparent cover is cleaned by the bristles, thereby improving the shooting quality. However, in actual use, the bristles and the arc rod are fixed to the first rotating shaft and the second rotating shaft, which is inconvenient to disassemble in the later stage. The bristles will age after long-term use, and if the bristles are not cleaned regularly, certain stains or dust will easily remain on the bristles during the cleaning process, which will reduce the cleaning effect of the bristles and affect the cleaning quality of the transparent cover.

[0005] An image acquisition device for an unmanned aerial vehicle is proposed to solve the above-mentioned problems. Utility Model Content
