Unmanned aerial vehicle undercarriage and anti-falling energy storage method

Abstract

The invention relates to an unmanned aerial vehicle undercarriage and an anti-falling energy storage method. The unmanned aerial vehicle undercarriage comprises an undercarriage body, the undercarriage body is damped after being folded / compressed, an energy storage device is arranged on the undercarriage body, the energy storage device is charged after the undercarriage body is folded / compressed, and the energy storage device is used for providing power when the undercarriage body is unfolded. The purpose of the invention is to provide buffering in a landing stage and store energy by adopting an energy storage device, convert gravitational potential energy of the unmanned aerial vehicle in the landing stage into elastic potential energy and store the elastic potential energy, and release the stored energy during takeoff, so that the elastic potential energy is converted into upward kinetic energy, thereby facilitating vertical takeoff of the unmanned aerial vehicle. Power consumption in the takeoff stage and electric energy in the descending stage are reduced.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to an unmanned aerial vehicle landing gear and an anti-drop energy storage method. Background technique [0002] Unmanned aerial vehicles are referred to as UAVs for short. UAVs can be divided into taxiing takeoff and landing and vertical takeoff and landing according to the takeoff mode. The landing gear of domestic vertical take-off and landing drones mostly uses skid-type landing gear with two poles on both sides or four pillars as the landing gear. These common structures can basically meet the take-off and landing performance requirements of small vertical take-off and landing drones, but there is a single structure , poor cushioning performance, poor stability, and can not protect the UAV in special circumstances during landing; compound wing vertical take-off and landing UAVs have a large take-off weight, and have high requirements for the load-ca...

The landing gear of domestic vertical take-off and landing drones mostly uses skid-type landing gear with two poles on both sides or four pillars as the landing gear. These common structures can basically meet the take-off and landing performance requirements of small vertical take-off and landing drones, but there is a single structure , poor cushioning performance, poor stability, and can not protect the UAV in special circumstances during landing; compound wing vertical take-off and landing UAVs have a large take-off weight, and have high requirements for the load-carrying of the landing gear and the stability of the aircraft during landing. Wing vertical take-off and landing drones only rely on four rotors to complete the landing when they land vertically, and there is a high possibility of abnormal landing during the landing phase. For example, the uneven power of the four rotors causes the drone to tilt; Due to the weakening of the battery power, the power system cannot reach the set pulling force, resulting in too fast descent. Ordinary landing gear will cause the UAV to receive excessive impact force, resulting in damage to the fuselage or damage to the precision instruments in the cabin due to huge impact force.

[0003] The landing gear of drones on the market has a single function, which cannot protect the drone against special circumstances during landing, nor can it store the energy during the descent to reduce the energy consumption of the drone

Traditional skid landing gear can absorb limited energy only by its own deformation
