Magnetic simulation muscle structure

Abstract

The invention discloses a magnetic simulation muscle structure which is provided with a first module, and a second module arranged in the first module; and the first module and the second module can be moved relatively through electromagnetic repulsion force. The simulation muscle structure is a simulation muscle device using the electromagnetic repulsion force, and a traditional driving mode using a servo motor as a robot is changed completely. Compared with another driving mode using electromagnetic attraction, the magnetic simulation muscle structure has the effects that the controllable expansion degree is achieved on the expansion stroke of simulation muscle is achieved, while the electromagnetic attraction can only attract and release once, namely that only one-time extension and contraction can be achieved, and the expansion degree of the electromagnetic attraction can not be controlled. Thus, the magnetic simulation muscle structure is achieved by using the repulsion force of amagnetic field, namely that not only can any expansion degree of the simulation muscle be achieved, but also control over the size of the required force can be achieved. Therefore, the magnetic simulation muscle structure has the advantages of high acceleration, low mechanical wear, small size, light weight, low noise, energy saving, high response speed, controllable expansion degree and other excellent driving characteristics.

Problems solved by technology

[0003] Compared with the traditional non-linear motor drive, the new device driven by linear motor has the advantages of simple structure, no contact wear, low noise, high precision, flexible combination and fast speed, etc., but the characteristics of the linear motor itself determine its own defects. : For example, the edge effect caused by the on-off of the magnetic circuit and the installation air gap are large; in addition, the traditional gravitational attraction mechanism still has the connection stroke that cannot be accurately controlled by the attraction, which makes the attraction connection extremely abrupt

In other words, as long as the electromagnetic attraction is triggered, the electromagnet will directly change from a static state to a moving state and will not stop on the stroke, but until it is attracted to the magnetic coil, which will make it impossible to control the electromagnet. In terms of the position of the magnetic circuit, it is impossible to realize the control of fine movements in practical applications, and it is not practical at all.
