Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] like Figures 1 to 2 As shown, the damping structure of a drone according to the present invention includes a support shaft 1 and a sleeve 2; the bottom end of the sleeve 2 is sealed; the inner cavity of the sleeve 2 is set There is an elastic element 14; the shaft body of the support shaft 1 matches the inner hole of the sleeve 2; the support shaft 1 is inserted into the sleeve 2 and fixedly connected with one end of the elastic element 14; the other end of the elastic element 14 is fixed on The sealing end surface of the sleeve 2; several energy-absorbing systems are evenly distributed on the side wall of the sleeve 2; the energy-absorbing systems are distributed on the sleeve 2; the energy-absorbing systems are used to absorb the support shaft 1 kinetic energy; the fuselage of the UAV is fixed on the top of the support shaft 1. During the landing process of ...

Abstract

The invention relates to the technical field of an unmanned aerial vehicle, in particular to a shock absorbing structure of the unmanned aerial vehicle, wherein the bottom end of the sleeve is sealed;The inner cavity of the sleeve is provided with an elastic element; The shaft body of the supporting shaft is matched with the inner bore of the sleeve; A support shaft is fixedly connected with oneend of that elastic element after being inserted into the sleeve; The other end of the elastic element is fixed on the sealing end face of the sleeve; Several energy absorption systems are uniformly distributed on the side wall of the sleeve; The energy absorption system is circumferentially distributed on the sleeve. The energy absorption system is used to absorb the kinetic energy of the supportshaft. When the invention is used, the support shaft can be quickly stationary relative to the sleeve by using the energy absorption system, the UAV can be prevented from reciprocating on the groundfor a long time during the landing process, the airframe parts are protected to a great extent, and the service life of the UAV is prolonged.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a shock-absorbing structure for drones. Background technique [0002] UAV is an unmanned aircraft controlled by radio remote control equipment and its own program control device. It is a general term for unmanned aerial vehicles and was first used in the military field. With the development and promotion of UAV technology, UAVs have been widely used in aerial photography, agriculture, forestry, surveying and mapping and other fields. Limited by the operational accuracy or the existing technical conditions, the UAV will inevitably be impacted by the strong reaction force on the ground when it takes off and lands, which will damage the UAV body and the precision parts erected on the UAV to a certain extent. Instrument, so it is necessary to carry out certain shock absorption treatment on the UAV. [0003] Most of the existing shock absorbing devices directly compress the gas ela...
