Buffer device with leg type structure

Abstract

The invention relates to a buffering device with a leg type structure. The buffering device comprises a device containing plate and a plurality of buffering energy-absorbing legs. According to the technology, the physiological structure and jumping characteristics of locust legs are used for reference, the contact rebound phenomenon between an aircraft and a target spacecraft is avoided, and kinetic energy is absorbed and converted into elastic potential energy to dissipate impact energy during collision contact. Therefore, the device can adapt to complex surface characteristics, has high efficiency, can effectively solve the key problems of smooth contact and stable landing of small aircrafts. In the invention, the six buffer energy-absorbing legs are uniformly distributed in the circumferential direction of a device placing plate (I); wherein the buffering and energy-absorbing legs achieve buffering and shock absorption through torsional springs and one-way bearings, rebound is avoided.The six-leg structure is adopted to increase the buffering load capacity, the buffering device can meet the requirement for non-forward collision contact buffering, and on the basis, the feet connected through the ball pairs have multiple degrees of freedom and can adapt to the irregular surface of a target object. The buffer device has universality and can provide application prospects and reference for buffering and shock absorption in other fields.

Description

technical field [0001] The invention relates to a buffer device with a leg structure, which belongs to the field of robots. Background technique [0002] With the profound development of China's space technology, deep space exploration and space station construction are progressing steadily, and more aircraft and probes will be sent to space. The safe interaction between aircraft and the stable landing of probes are the key factors for spacecraft to perform space operations. , The premise of improving efficiency. In the field of space robots, how to stably attach high-speed flying vehicles to spacecraft has high scientific research value. The space vehicle will generate a large impulse when it moves at high speed, which makes the vehicle generate huge instantaneous energy when it comes into contact with the spacecraft in a gravity-free space environment, causing the vehicle to be quickly bounced off, making the vehicle unable to attach stably to the space vehicle. on the s...
