Multicopter

Multicopter optimized with a multi-stage detachable wing support and socket coupling structure

This technology is a structural optimization for multicopter airframes that features a multi-stage detachable wing support (first and second supports) to allow for easy attachment, detachment, and vertical angle adjustment, while stabilizing mechanical and electrical connections through an integrated electrical connector and socket structure.

As multicopters have grown in size due to the mounting of equipment such as cameras, they have become difficult to transport and store. Furthermore, there have been limitations in structural design regarding the ability to secure sufficient thrust, maintain flight stability, withstand wind resistance, and protect the airframe during a crash.

This technology incorporates an angle adjustment unit using a rotation center pin and a fixing pin between the airframe and the wing support. It also introduces an electrical connection (plug/cord) and socket coupling structure that allows the second support to be inserted into and detached from the first support, ensuring ease of disassembly and transport. Applicable to unmanned aerial photography, surveillance, reconnaissance, and environmental monitoring, it improves flight stability and wind resistance while facilitating easier transport and storage.

Key Features:

• Wing supports provided along the circumference of the airframe, capable of vertical angle adjustment
• A first support coupled to the airframe with adjustable angles, and a second support that is detachably fitted to the first support and to which the wings are attached
• An electrical connector provided to enable electrical connection between the first and second supports when they are coupled together
• A socket fitted to the outside of the second support to restrict movement, into which the first support is inserted and secured with screws
