Abstract
Description
Technical Field
[0001] The utility model relates to a vehicle-mounted hoisting bracket, in particular to a hoisting bracket capable of effectively protecting an unmanned aerial vehicle (UAV) during transportation or storage, belonging to the technical field of special vehicle accessories. Background Art
[0002] Unmanned aerial vehicles (hereinafter referred to as UAVs) are widely used in aerial reconnaissance, surveillance, communication, anti-submarine and electronic jamming. In actual use, UAVs need to be frequently stored and transported between different locations. Since the UAV carrying platform is a mobile platform, when hoisting the UAV, the UAV is directly hoisted in and out of the carriage and fixed to the carrying platform only through devices such as mooring ropes using a hoisting mechanism, and the front and rear wheels of the UAV cannot be positioned and adjusted. This not only makes hoisting difficult and unreliable, but also causes the UAV to be unable to be effectively protected during transportation and storage. In severe cases, it will affect the vehicle's driving, and there are safety hazards for the vehicle and personnel. If an integrated platform for automatic leveling and azimuth adjustment is adopted, its cost is extremely high. Summary of the Utility Model
