Safety fastener device suitable for fixing cabin of unmanned helicopter

Abstract

The invention discloses a safety fastener device suitable for fixing a cabin of an unmanned helicopter. The safety fastener device comprises an upper fastener, a lower fastener, an annular locking buckle and a quick release pin, wherein the upper fastener is fixedly connected with the upper cabin cover, and the lower fastener is fixedly connected with the main cabin body; the key structures such as the upper fastener, the lower fastener, the annular locking buckle and the quick release pin are combined and assembled, so the peripheral surface and multiple directions of the connecting piece canbe fastened at the same time, structural reliability and stability of the connecting piece are guaranteed, and the design requirement for fixing the cabin of the unmanned helicopter is met.

Description

technical field [0001] The invention relates to the technical field of unmanned helicopter equipment, in particular to a safety fastener device suitable for fixing the cabin body of an unmanned helicopter. Background technique [0002] An unmanned helicopter refers to a vertical take-off and landing (VTOL) unmanned aircraft that is controlled by radio ground remote control or / and autonomously. In the past ten years, with the research progress of composite materials, power systems, sensors, especially flight control and other technologies, unmanned helicopters have developed rapidly and are increasingly becoming the focus of attention. [0003] Unmanned helicopters have unique flight performance and use value. Compared with manned helicopters, unmanned helicopters have incomparable advantages in many aspects due to the characteristics of no casualties, small size, low cost, and strong survivability. In terms of civilian use, unmanned helicopters have broad application prosp...

AI Technical Summary

Problems solved by technology

[0004] Researchers have developed and designed a new type of unmanned helicopter system. The unmanned helicopter system is generally composed of a helicopter body, a control and navigation system, an integrated radio system, and mission load equipment; the helicopter body adopts a split design , the helicopter body is composed of an upper hatch cover and a main cabin body. The connection between the upper hatch cover and the main cabin body is generally fixed with rivets or screws, but neither of these two connection methods can achieve the technical requirements of quick disassembly and safety and reliability. ;For example, the rivet connection method cannot be quickly disassembled, and it is very inconvenient to disassemble. However, the screw connection method is also labor-intensive and time-consuming to disassemble, and the connection reliability is not stable.
