Problems solved by technology

The arched landing gear has the disadvantages of heavy weight, large volume, and poor portability, which affect the flight time of the UAV and the convenience of packaging and transportation; the straight-rod landing gear has the characteristics of small size and light weight, but it does not have arms. The locking function requires an additional design of a locking mechanism, which undoubtedly increases the number of parts and thus increases the weight of the body; the retractable landing gear has the portability of being foldable and recyclable, but it also does not have the arm locking function

Embodiment

[0067] 1. Install and fix

[0068] Glue the locking button 2 with the upper casing, glue the bottom button 7 with the lower casing, connect the landing gear support rod 5 and the locking rod 4 through the opening bayonet pin 6, and connect the arm shaft 8 and the energy-absorbing shrapnel 3 Put them between the upper body shell 10 and the lower body shell 9 in sequence, and then pass the locking rod 4 through the lower body shell 9, the bottom button 7, the arm shaft 8, the energy-absorbing shrapnel 3, and the lock The button 2 and the body upper shell 10 lock the locking rod 4 with the locking cap 1 above the body upper shell 10 .

[0069] 2. Arm deployment and recovery

[0070] Arm unfolding process: the first step is to rotate the arm to a specific unfolding angle, which is determined by the stop surface of the locking button 2 and the position of the groove. The second step is to break down the landing gear support rod 5 in turn. The upper end of the landing gear support...

Abstract

The present invention provides a light-duty folding multi-rotor aircraft arm locking reusable landing gear and its use method as well as an unmanned aerial vehicle. structure, the landing gear support rod is connected to the locking rebound structure through a fixed structure. The landing gear of the present invention is simple in mechanism and high in reliability. It is similar in appearance to the straight-rod landing gear. It has the advantages of small size, light weight, foldability and good portability. A small multi-rotor drone with foldable arms.

Description

【Technical field】 [0001] The invention relates to the technical field of mechanism design of aviation aircraft, in particular to a light-duty folding multi-rotor arm-locking reversible landing gear and an unmanned aerial vehicle. 【Background technique】 [0002] Small multi-rotor drones are currently widely used in fields such as plant protection, line inspection, security, and target reconnaissance. In order to ensure the portability and rapid recovery of small multi-rotor drones, it is necessary to design connection locking mechanisms for some components. [0003] The flight duration of a small multi-rotor UAV is an important indicator for its performance assessment. How to reduce the weight of the airframe as much as possible and improve the strength-to-weight ratio of the airframe while ensuring the carrying capacity of the airframe is what aircraft design engineers have been studying. question. The landing gear is an important part of the small multi-rotor UAV, which is...
