Bionic jellyfish foot and mechanical jellyfish applying bionic jellyfish foot

Abstract

The invention belongs to the technical field of bionic machinery, and particularly relates to a bionic jellyfish foot and a mechanical jellyfish applying the bionic jellyfish foot. The bionic jellyfish foot comprises a first hinge point, a second hinge point, a third hinge point and a fourth hinge point, and is characterized in that a power assembly is arranged at the datum line and drives the second hinge point and the third hinge point to generate synchronous reciprocating linear motion in the length direction of the datum line, or the power assembly drives the first hinge point and the fourth hinge point to generate synchronous reciprocating linear motion in the length direction of the datum line, and each hinge point correspondingly drives the corresponding connecting rod to generate afollow-up action, so that a high bionic action function on the jellyfish foot is realized. The invention further provides a mechanical jellyfish based on the bionic jellyfish foot, which is particularly suitable for science and education propaganda or unmanned underwater navigation occasions.

Description

technical field [0001] The invention belongs to the technical field of bionic machinery, and in particular relates to a bionic jellyfish foot and a mechanical jellyfish using the bionic jellyfish foot. Background technique [0002] Bionics is an interdisciplinary subject that combines engineering technology and biological science developed in recent years. The purpose is to analyze biological processes and structures, and use the obtained analysis results for future design. In bionics, through the understanding and analysis of jellyfish, it has been found that compared with wave-propelled fish, it has the advantages of concealed movement, small size, light weight, high flexibility and low metabolic rate, and can effectively use the water to swim. Characteristic, therefore, people are committed to realizing the biomimicry to jellyfish always. At present, on the one hand, jellyfish bionics is used in science and education publicity, such as science and technology museums, etc...

AI Technical Summary

Problems solved by technology

In the bionic research of jellyfish, how to imitate the elegant movement of jellyfish is the key point. Most of the existing technologies are described in the invention title of "a bionic mechanical jellyfish" with the Chinese patent announcement number "CN108146599A": the jellyfish head, jellyfish body It is composed of jellyfish tail, among which, jellyfish body is equipped with various sensors, encoders, and control panels; jellyfish head is equipped with GPS locator, power indicator light and antenna; jellyfish tail is equipped with power supply and multi-functional expansion interface; Most of the existing technologies focus on signal control and neglect motion management. There are very few bionic studies on the most important marching motion of jellyfish. The scientific and educational effect is poor; and when used as underwater navigation equipment, the above-mentioned rigid foot movements obviously cannot achieve the ideal water propulsion effect, and can only rely on additionally loaded propulsion components such as propellers to realize the traveling function, which cannot be effective Using the inherent concealment of jellyfish, etc., needs to be solved urgently
