Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and particularly relates to a load quick disassembly device for a large-load unmanned aerial vehicle. Background Technique

[0002] At present, the technology of unmanned aerial vehicles has developed and been applied quite rapidly, and has been widely used both in military and people's daily lives, solving problems in related fields. The unmanned aerial vehicle itself can carry a certain weight of materials. For example, it is used to transport fertilizers, pesticides, and picked fruits in mountainous areas, and there are also unmanned aerial vehicles used to drop materials at rescue and disaster relief sites, all of which can realize the function of material transfer through remote control.

[0003] According to a load quick disassembly device for a large-load unmanned aerial vehicle (authorization announcement number: CN221757767 U) disclosed on the patent network, it is described that "the utility model belongs to the technical field of unmanned aerial vehicles, and particularly relates to a load quick disassembly device for a large-load unmanned aerial vehicle, including an unmanned aerial vehicle frame. An installation device is arranged at the upper end inside the unmanned aerial vehicle frame, and the installation device includes a disassembly and assembly unit and an auxiliary unit. For this load quick disassembly device of the large-load unmanned aerial vehicle, by setting the disassembly and assembly unit, the drawable carrying board is slowly inserted along the sliding groove opened by the drawable groove assembly. When the retaining piece is located at the rear end of the clamping block, the spring will push the clamping block to pop out from the fixed block to limit the retaining piece, thereby fixing the drawable carrying board. When it is necessary to disassemble the drawable carrying board, the drawable carrying board is pulled out along the drawable groove assembly, thus realizing quick disassembly, and solving the problem that when the existing large-load unmanned aerial vehicle mounts third-party equipment, it is mounted on the unmanned aerial vehicle through a pipe rack, or directly fixed on the body of the unmanned aerial vehicle, or fixed with screws, and all require tools during disassembly and assembly, and the disassembly is very inconvenient."

[0004] Regarding the above description content, the applicant believes that there are the following problems:
