Problems solved by technology

[0005] Aiming at the problems that the undercarriage of the UAV cannot be folded, takes up a lot of space when it is stored, and is inconvenient to carry, the invention designs a quick folding mechanism. After the undercarriage is folded, it fits with the cantilever and is fixed on the cantilever, effectively preventing retraction. The random shaking of the rear landing gear, the design fully highlights the quickness and reliability of the mechanism

Abstract

The invention relates to a design of a rapid retractable and folding mechanism for a landing gear of a multi-rotor unmanned aerial vehicle. A locking mechanism can be used to quickly unfold or fold the landing gear and lock it. The locking mechanism includes a housing, a guide post and a return spring. The guide post is two straight arms connected to the bottom wall to form an integral U-shape, one of which is shorter than the other. The lugs are provided with through holes for passing through the two straight arms of the U-shaped guide post, and the end of the landing gear is provided with symmetrical connecting lugs that can respectively fit the two lugs of the motor seat from the outside. There are two limit holes on the lugs, and the short straight arms passing through the through holes on the lugs of the motor base are respectively inserted into the two limit holes to lock the landing gear in the unfolded working position, or in the folded retractable position. Location. Using this folding mechanism can quickly and conveniently open and retract the landing gear, which is beneficial to save a lot of installation and disassembly time when the multi-rotor UAV system is in use.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a landing gear folding mechanism of an unmanned aerial vehicle. Guided by this plan, the finished UAV landing gear can save frequent installation and disassembly processes, saving a lot of time, and the landing gear takes up less space after folding, and has better environmental applicability. Background technique [0002] Multi-rotor UAV is actually an aircraft with multiple rotors. Because of its simple structure, low cost, and easy manipulation, it can integrate multiple loads to complete complex tasks. It has been widely used in the military industry and social life industry. s concern. Multi-rotor drones can be used in border defense monitoring, military investigation, police and fire monitoring and other industries, and can also be widely used in aerial photography and photography. The field of use of drones is becoming wider and wider, and the applicatio...
