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 an aircraft arm body and communicating inside and outside, a lock arranged on the aircraft arm body and capable of being slidably matched with the guiding hole and an eccentric wheel driving mechanism connected with the lock and arranged on the aircraft arm. The eccentric wheel driving mechanism comprises an eccentric wheel movably connected with the lock and a rotating shaft connected with the eccentric wheel, the eccentric wheel conducts axial movement around the rotating shaft and drives the lock to conduct linear motion in the guiding hole, 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 eccentric wheel driving structure is mainly utilized to drive the lock to conduct the linear motion on the guiding hole formed in the connecting end of the aircraft arm body and communicating inside and outside, 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 aircraft arms. 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 photography. [0003] Existing aircraft often consists of an aircraft fuselage and an aircraft arm extending from the aircraft fuselage to the outside. Motors and propellers are installed on the outer ends of the aircraft arms to drive the flight of the aircraft. The lower part of the aircraft is also provided with feet. frame to facilitate the landing of the aircraft. [0004] However, in the existing aircraft, the stretched aircraft arms and tripods are all fixedly connected to the fuselage. After use, the large arm span makes the aircraft ...

Problems solved by technology

[0004] However, in the existing aircraft, the stretched aircraft 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. Due to the weight reduction of the aircraft itself, 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
