Embodiment Construction

[0045] The present invention will be further elaborated below in conjunction with embodiment.

[0046] The present invention provides a reusable rigid-flexible double-working mode landing buffer device, which can buffer the impact force of the ground during the landing process, and lock the buffer spring after the buffer is over to prevent it from reciprocating vibration causing aircraft or robots overturned. In addition, the rigid working mode of the buffer device can fix the length of the buffer device at a specified length, eliminate the vibration caused by the buffer device during the working process of the aircraft or robot, and enhance the stability and safety of the aircraft or robot. In addition, the length of the buffer device can be fixed at different positions within the adjustable range, enabling the aircraft or robot to crawl on a larger slope and walk sideways on the slope, so as to increase the overturning angle of the aircraft and robot, and at the same time ad...

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...
