Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, and in particular relates to a detachable and foldable structure for a machine arm and a three-way connection structure including the structure. Background Technology

[0002] The arms of multi-rotor drones occupy a large portion of their volume. Therefore, in production and use, clips are installed at the connection points between the arms and the fuselage to allow for folding or direct disassembly of the arms, minimizing their size during transport and storage. However, current technologies either allow only folding or disassembly. While quick folding is most convenient for transport, this structure is often fixed. If disassembly is needed due to arm damage, the operation is cumbersome and requires special tools. While detachable structures offer easier replacement, removing all arms is time-consuming when the drone needs to be folded and moved during use. Furthermore, current drone structures tend to... The number of rotors on an arm varies, sometimes one, sometimes two. Existing technologies often cannot achieve rapid switching. At the same time, the arm often contains numerous cables, which are usually routed separately with individual plug-in interfaces at joints or disassembly points. When folding or disassembling, the cables need to be plugged in and unplugged individually. This is not only complicated, but the separate cable connection structure is also prone to damage during disassembly or folding due to operational errors such as forgetting to unplug the cables. Therefore, developing a structure that can be folded, disassembled, and quickly switched between different numbers of arms, while also facilitating rapid plugging and unplugging of cables, has been a problem that those skilled in the art have been pondering.
