A Reusable Landing Buffer Device with Rigid and Flexible Dual Modes

Abstract

The invention relates to a reusable landing buffer device with dual modes of rigidity and flexibility, which includes a telescopic tube, a buffer spring, and a telescopic seat; one end of the outer wall of the telescopic tube and one end of the telescopic seat are socketed together to form a buffer core; the buffer spring sleeve On the outside of the buffer core, under the joint action of external force and the buffer spring, the telescopic seat can slide relative to the telescopic tube; M limit ball sockets and N buffer ball sockets are arranged on the inner surface of the telescopic tube; M limit electromagnet components and N buffer electromagnet components, the limit electromagnet components are used to cooperate with the limit ball socket, control the buffer device to work in the rigid working mode, and the length of the buffer core is fixed at the specified length; the buffer electromagnetic The iron component is used to cooperate with the buffer ball socket, and the buffer device is controlled to work in the buffer mode. During the buffer process, the buffer spring is compressed to absorb the impact energy generated by the external force. After the energy absorption process, the length of the spring will be automatically locked.

Description

technical field [0001] The invention relates to a rigid-flexible double-mode reusable landing buffer device, which belongs to the technical field of landing and buffering of aerospace vehicles and robots. Background technique [0002] Aircraft and robot landing buffer technology is used to protect aircraft and robots from being damaged when they are subjected to ground impact force during landing. Due to the complex landform environment, the buffer device needs to absorb the impact energy through the elastic medium during the landing process. After the energy is completely absorbed, the energy is dissipated through the damping device or material. [0003] At present, the buffer devices that have been adopted abroad include airbag buffer devices, compressible energy absorbers, air pressure buffers, hydraulic buffer devices, magnetorheological buffer devices, electromagnetic damping buffer devices and mechanical spring buffer devices. [0004] In the space environment, the re...
