Locking mechanism of aircraft arm

Abstract

The invention discloses a locking mechanism of an aircraft arm. The locking mechanism comprises an aircraft arm and an aircraft arm mounting base used for connecting the aircraft arm to an aircraft main body. The locking mechanism comprises a guiding hole formed in the connecting end of the aircraft arm and communicating inside and outside, a lock capable of being slidably matched with the guiding hole and a pull pin connected with the lock and arranged on the aircraft arm are arranged in the guiding hole, the lock conducts linear motion in the guiding hole along with the pull pin, and the front end of the lock is in attached contact with or away from the surface of a clamping plate arranged on the aircraft arm mounting base. According to the locking mechanism of the aircraft arm, the purpose that the aircraft arm can freely extend / be folded is achieved, the pull pin connected with the lock and arranged on the aircraft arm is mainly utilized, the lock conducts linear motion in the guiding hole along with the pull pin, the front end of the lock is in attached contact with or away from the surface of the clamping plate arranged on the aircraft arm mounting base, and locking / unlocking of the aircraft arm is achieved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a locking mechanism for an aircraft arm. Background technique [0002] At present, aircraft or unmanned aerial vehicles have been more and more widely used in social life, for close-range observation of places that are difficult for people to reach, or for high-altitude aerial photography, which provides convenience for observation and shooting. [0003] Existing aircraft often consists of an aircraft fuselage and a machine arm extending from the aircraft fuselage to the outside. Motors and propellers are installed at the outer ends of the machine arms to drive the flight of the aircraft. A tripod is also provided at the bottom of the aircraft. to facilitate the landing of the aircraft. [0004] However, in the existing aircraft, the stretched arms and tripods are all fixedly connected to the fuselage. After use, the large arm span makes the aircraft have higher requireme...

Problems solved by technology

[0004] However, in the existing aircraft, the stretched arms and tripods are all fixedly connected to the fuselage. After use, the large arm span makes the aircraft have higher requirements for storage space. The weight of the aircraft itself needs to be considered, and the structure of each part of the aircraft is relatively simple. Therefore, the large arm span also leads to the danger of easy damage caused by improper storage
