Description

Technical Field

[0001] This utility model specifically relates to a multi-functional load suspension device for unmanned aerial vehicles (UAVs), belonging to the field of UAV technology. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and their own programmed control devices, or operated autonomously, either completely or intermittently, by an onboard computer. Compared to manned aircraft, UAVs are often better suited for dangerous missions. UAVs can be categorized into military and civilian applications. In the military field, UAVs are divided into reconnaissance aircraft and target drones. In the civilian field, the combination of UAVs with industry applications represents the true necessity of UAVs. Currently, applications in aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news reporting, power line inspection, disaster relief, film and television shooting, and creating romantic scenes have greatly expanded the uses of UAVs. Developed countries are also actively expanding industry applications and developing UAV technology.

[0003] A search revealed a publicly available patent (publication number: CN212667694U) for a multi-functional payload suspension device for unmanned aerial vehicles (UAVs). The patent describes a device comprising a connecting plate with a pair of connecting rods symmetrically mounted on both sides of its bottom. The bottom ends of the two pairs of connecting rods are connected to a support plate. A suspension device is fixedly connected to the center of the bottom of the connecting plate. The suspension device consists of a main housing, a mounting plate, and a secondary housing. The top of the main housing is fixedly connected to the connecting plate. A mounting groove is provided at the bottom of the main housing, and the mounting plate is installed inside the mounting groove. A turntable is movably engaged on the bottom surface of the mounting plate, and a fixing seat is fixedly connected to the bottom end of the turntable. Axle pins are fixedly connected to both sides of the secondary housing and are fixedly installed to the fixing seat via the axle pins. This multi-functional payload suspension device for UAVs has a simple and reasonable structure, a novel design, and is easy to operate. It effectively solves the problem of existing UAV camera suspension devices being inconvenient for adjusting and using the camera, and has high practical value.

[0004] However, the aforementioned patent still has some shortcomings. For example, when the drone is flying at high altitude, there will be mosquitoes at high altitude. When the mosquitoes hit the viewing window, their corpses will remain on the surface. When the scraper is used to scrape, it will not only fail to make the viewing window clearer, but will also spread the mosquito corpses evenly on the window, thus affecting the use of the camera.
