Retractable type aircraft damping mechanism

Abstract

The invention relates to a retractable type aircraft damping mechanism, comprising a retaining ring, a telescopic cylinder, a subbase, installation columns and damping springs. Through holes are formed in the retaining ring and the subbase, the upper end of the telescopic cylinder is connected with the retaining ring, the lower end of the telescopic cylinder is connected with the subbase, the damping springs are uniformly distributed on the outer side of the telescopic cylinder, the upper ends of the damping springs are connected to the lower end face of the retaining ring though the installation columns, and the lower ends of the damping springs are connected to the upper end face of the subbase through the installation columns. The retractable type aircraft damping mechanism is retracted under the effect of gravity and recoil force, thus the shaking force transmitted to the aircraft per se is effectively reduced, aerodynamic damping and spring damping are applied to the retractable type aircraft damping mechanism, the structure is simple and the damping effect is good.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a retractable aircraft damping mechanism. Background technique [0002] Aircraft is an instrumental flying object manufactured by humans, capable of flying off the ground, flying in space and controlled by humans in the atmosphere or in space outside the atmosphere (space). Aircraft are divided into aircraft, spacecraft, rockets, missiles and guided weapons UAV is also a kind of aircraft. UAV is an unmanned aircraft controlled by radio remote control equipment and its own program control device. From a technical point of view, it can be divided into unmanned helicopters, unmanned fixed-wing aircraft, and unmanned aircraft. Multi-rotor aircraft, unmanned airships and unmanned parawing aircraft, etc.; can be divided into military and civilian use according to the application field, and military drones are divided into reconnaissance aircraft and target drones; at present, drones can be wide...

AI Technical Summary

Problems solved by technology

[0003] The aircraft has the advantages of compact structure, small size, strong popularity, flexible movement and stable flight, and is widely used in civilian and military applications, and is popular with the public; It determines the flight time and stability of the aircraft, while the shock absorption directly determines the stability and safety of the aircraft when it lands, and indirectly affects the quality of the aircraft itself and the safety of the objects or people it carries.

There are also some technologies that have proposed solutions to the vibration damping problem of aircraft. For example, the Chinese patent No. 201510270375.4 discloses a kind of aircraft damping tripod. The sleeve and the inner shaft pass through the oil seal to form an internal sealing structure. Under the action of the resistance grease, the spring makes the expansion and contraction of the inner shaft play a buffering and shock-absorbing effect; the Chinese patent No. 201410012150.4 discloses a shock-absorbing device for an unmanned aerial vehicle, and the shock-absorbing effect is achieved by setting a shock-absorbing ball; However, the above technologies all have problems such as ineffective shock absorption.
