multi-link jumping mechanism

Abstract

The invention discloses a multi-connection-rod jumping mechanism. The multi-connection-rod jumping mechanism comprises a rack, a multi-connection-rod mechanism, an elastic element, an energy storage assembly and a triggering device. The energy storage assembly is used for stretching the elastic element in a non-return mode. The triggering device can relieve the non-return function of the energy storage assembly to make the elastic element rebound. Resilience of the elastic element is used for driving the multi-connection-rod mechanism to be subjected to momentary deformation and pushing the multi-connection-rod mechanism to move upwards to achieve jumping through reactive force of connection rods and the ground during deformation. The multi-connection-rod jumping mechanism is simple in structure and capable of walking on a flat terrain and jumping when running into a barrier, ditches and other complex rugged terrains, and thus the passing performance of a robot is improved greatly.

Description

technical field [0001] The invention relates to the field of jumping mechanisms, in particular to a multi-link jumping mechanism. Background technique [0002] With the expansion of the application range of robots, robots are often required to have jumping devices to jump over obstacles or ditches in practical applications. For example, in some special environments such as archaeological exploration, interstellar exploration, military reconnaissance and anti-terrorism activities, robots must It has strong terrain adaptation and autonomous movement ability. Robots in the prior art mainly have two modes of movement, one is wheeled or belt-driven, which is the driving mode of most mobile robots, ranging from various remote control toy machine cars or autonomous machines Small cars, as large as unmanned vehicles on the battlefield or alien surface detectors in interstellar exploration; the other is bionic crawling or walking, such as snake robots, robot cats, robot dogs and var...

AI Technical Summary

Problems solved by technology

There are at least the following disadvantages in the above-mentioned prior art: wheeled and crawler robots can only work on flat terrain, and once the terrain is uneven, their movement will be greatly restricted; the ability of walking or crawling robots to climb over obstacles is slightly stronger, but their freedom High degrees, a large number of joint drivers make the control complex, the movement is slow, and when the obstacle is larger than its own size, it is difficult to climb over smoothly
