Description

Technical Field

[0001] The invention belongs to the technical field of unmanned aerial vehicle lifting platforms, and in particular relates to a vehicle-mounted take-off and landing lifting platform for a rotary-wing unmanned aerial vehicle. Background Art

[0002] A drone is an unmanned aircraft controlled by a radio remote control device or an onboard computer program control system. In recent years, with the rapid development of drone technology, drones have been widely used in many fields, especially in agriculture. However, drones are mostly used for agricultural operations in the field, which has the characteristics of complex operating environment and poor take-off and landing conditions, so a take-off and landing platform is needed for assistance.

[0003] However, most of the drone landing platforms on the market are fixed and cannot be adjusted. In addition, the existing drone landing platforms lack corresponding protective fixing structures. When the drone is landed and not in use, the volume on the platform is tilted or tipped over by external forces, which makes it easier to be damaged. Especially for vehicle-mounted drones, since the platform is prone to shaking during vehicle movement, it is more likely to cause damage to the drone. In the prior art, vehicle-mounted drones are mostly fixed by manually using buckles or strapping tapes. Not only is the fixing operation inconvenient, the drone is easily damaged during the fixing process, and the drone needs to be manually released again when in use, affecting the use of the drone.
