A Landing Gear Shock Absorbing Structure for Near Space Solar UAV

Abstract

The invention discloses a landing gear damping structure for a solar-powered unmanned aerial vehicle in an adjacent space, which includes a mounting plate, a chute is opened on the mounting plate, and a counterweight slider is slidably connected to the chute. One side of the counterweight slider is fixedly connected with an adjusting pin, the chute is provided with an elastic mechanism, the mounting plate is connected with a fixed plate through two sets of first buffer mechanisms, and the bottom side of the mounting plate is fixedly connected with a sealing seat A piston rod is fixedly connected to the fixed plate, a traveling device is provided at one end of the piston rod, and a first sealing chamber is opened in the sealing seat. In the present invention, by shortening the distance between the first powerful magnet and the second powerful magnet, the repulsive force between the first powerful magnet and the second powerful magnet is gradually increased, and the two-stage Buffering and shock absorption, so as to cooperate with the buffer spring for shock absorption, enhance the buffering effect and share the fatigue strength of the buffer spring.

Description

technical field [0001] The invention relates to the technical field of landing gear of unmanned aerial vehicles, in particular to a landing gear shock-absorbing structure for near-space solar-powered unmanned aerial vehicles. Background technique [0002] Near space refers to the airspace 20 to 100 kilometers away from the ground. Due to its important development and application value, it has attracted widespread attention in the world. UAV is also an important survey tool in airspace. UAV + industry application is the real The current application in aerial photography, agriculture, plant protection, infectious disease monitoring, surveying and mapping, news reporting, power inspection, disaster relief, etc. has greatly expanded the use of drones themselves, and developed countries are also actively expanding industry applications and the development of drone technology. [0003] Landing gear is used for the take-off and landing of drones, especially for landing, the cushio...

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: most of the traditional landing gears use springs for landing buffering and shock absorption, the effect of buffering and shock absorption is limited, and the fatigue strength of a single spring buffer is too large for the spring itself , will reduce its normal service life, and its elasticity will gradually weaken as the use time increases, and the cushioning effect will become worse and worse, so it has to be replaced frequently, which virtually increases the cost of use. In order to solve the above problems, We propose a landing gear shock-absorbing structure for near-space solar-powered drones
