A Flat Peristaltic Crawling System Based on Helical Auxiliary Mechanism

Abstract

The invention discloses a flat creeping system based on a screw pair mechanism. The flat creeping system is synergistically composed of a plurality of mechanical bionic joint units. An up-down supporting module utilizes a screw pair to transfer circular movement into linear movement, so that the up-down movement of a supporting platform or a supporting base is completed. A front-back moving modulemakes the direction of the motor output power to be changed through a bevel gear, the circular movement is changed into the linear movement through a gear and a rack, so that the front-back movementof a foot or the supporting platform is completed. A control module utilizes a travel switch to promote next movement at a limiting position, thus circulatory movement and alternate movement of the front-back moving module or the up-down supporting module are achieved, and accordingly marching forward of each joint unit is achieved. Marching forward, steering and obstacle climbing of the flat creeping system are achieved through synergism of each joint, by adopting the flat design, the whole height is lowered, the fighting efficiency is improved, the energy expenditure of soldiers is reduced,and the area of a bomb landing face is decreased.

Description

technical field [0001] The invention relates to a flat peristaltic crawling system based on a spiral auxiliary mechanism. By imitating the body movement posture of snakes when stretching and crawling, the flat design is used to realize the automation of crawling and crawling of individual soldiers in wartime. It belongs to the flat peristaltic crawling system that improves combat efficiency, reduces the physical energy consumption of soldiers, and reduces the projectile surface area. Background technique [0002] Individual soldiers crawling forward in a low profile are used to use low cover to quickly and covertly approach the target or pass through obstacles under enemy fire. Our army's individual soldiers crawl forward in a low profile on the basis of lying down, using their arms to push the ground and their feet to move forward in unison. However, in training or actual combat, there are still many things to be improved in low-profile creeping forward. [0003] 1) When ...
