Landing buffering device for unmanned aerial vehicle

Abstract

The invention discloses a landing buffering device for an unmanned aerial vehicle. The landing buffering device comprises an outer bag and an inner bag which is composed of an inflation framework. After being inflated, the inflation framework of the inner bag comprises four cylindrical main air columns in the same shape, the top surfaces of the main air columns are located on the top plane, and the bottom surfaces of the main air columns are located on the bottom plane. The main air columns are connected through side air columns and the projections of the side air columns on the top plane are distributed along the sides of a rectangle. The outer bag is used for wrapping the inner bag and is in a rectangular solid shape or a cube shape after being inflated, the height of the outer bag is larger than or equal to that of the main air columns, and the projection of the outer bag on the top plane covers the projections of the main air columns and the side air columns. The landing buffering device for the unmanned aerial vehicle can be in a fixed square shape after being inflated, the fixed shape of the unmanned aerial vehicle can be guaranteed in the landing process of the unmanned aerial vehicle, even though the unmanned aerial vehicle is affected by air resistance, the unmanned aerial vehicle does not impact on the ground directly, and therefore the good unmanned aerial vehicle protection effect can be achieved.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles, and more specifically relates to an unmanned aerial vehicle landing buffer device, which can quickly inflate when the unmanned aerial vehicle lands, and plays the role of shock absorption and buffering. Background technique [0002] UAVs are used in a wide range of fields, and domestic UAV technology is becoming more and more mature. UAVs have the advantages of being able to adapt to complex and harsh environments, flexible in design, small in size, and long in duration without causing loss of personnel. In order to ensure that UAVs are safe and undamaged during emergency landings, reduce the cost of UAVs and reuse them, it is usually necessary to set up UAVs with emergency landing protection devices. [0003] At present, the UAV landing buffer device helps the parachute to buffer the connecting rod. Through the tension buffer component in the connecting rod, it plays a buffering role, so...

Problems solved by technology

[0005] In view of the above defects or improvement needs of the prior art, the purpose of the present invention is to provide a landing buffer device for unmanned aerial vehicles, wherein by improving its key buffer airbag structure, shape and setting method, it is different from the prior art. It can effectively solve the problem that the fuselage of the UAV directly hits the ground during the descent process, and the buffer device can maintain a fixed shape during the descent process of the UAV, which is not easy to cause the UAV fuselage to tip over, making the buffer device Can maintain a stable cushioning effect under different usage environments
