A bionic crawling mechanism

By using a drive module to drive the inner crank and connecting rod transmission in the bionic crawling device, the inner and outer cranks are driven to make elliptical cone motion, which solves the problems of large support fluctuation and insufficient stability, and achieves a more stable crawling effect and miniaturization of the device.

AI Technical Summary

⚠Technical Problem

Existing biomimetic crawling devices suffer from significant vertical fluctuations in their support structure during crawling, resulting in insufficient stability and making miniaturization difficult.

⚗Method used

The drive module drives the inner crank and connecting rod transmission, which in turn drives the inner and outer cranks to make elliptical conical motion. The phase difference between the two sets of spatial crank structures achieves stable support of the bracket and reduces the vertical fluctuation.

🎯Benefits of technology

It further reduces the amplitude of vertical fluctuations during crawling, improves crawling stability, and has a compact structure that is easy to miniaturize.

Abstract

The utility model relates to bionic technology field especially is a kind of bionic crawling mechanism, including drive module, support and at least one pair of crawling mechanism, drive module is equipped in support, each pair of crawling mechanism includes two groups of space crank structure and two connecting rods, two groups of space crank structure respectively with two connecting rods one-to-one corresponding cooperation;The outside end of two groups of space crank structure is in low position and undertakes support;Space crank structure includes the inner crank, fulcrum and outer crank connected in order from inside to outside, and one end of connecting rod is drivenly connected with the output end of drive module;The inner end of inner crank is drivenly connected with the middle part of connecting rod, and fulcrum is rotatably connected with support;Drive module drives inner crank movement via connecting rod, to drive outer crank movement.The utility model adds connecting rod transmission between inner crank and drive module to drive inner crank to make elliptic cone movement or approximate elliptic cone movement, and the up-and-down fluctuation amplitude when crawling is reduced, and crawling efficiency is higher, and stability is better.
