AI Technical Summary

Problems solved by technology

The cylinder can be pushed and pulled, and the force is directly related to the air pressure. The force-to-weight ratio can reach more than 50, but the movement is slow and cannot simulate biological movement. The muscles can be fast or slow, the pulling force can be large or small, and the changes are real-time.
The deforming cavity is generally made of 3D printed pleated plastic. When it is inflated, it will generate pulling force or pushing force. The force end is soft and the force-to-weight ratio can reach more than 100. However, the movement life is short and it is easy to break. The stroke is very short, and it is impossible to simulate the characteristics that the muscles can be fast or slow, the pulling force can be large or small, and the changes are real-time.

Description

technical field [0001] The invention relates to the technical field of electric control, in particular to an electric power cylinder. Background technique [0002] With the advancement of science and technology, products in the field of bionics have developed rapidly. Among them, artificial muscle is an example of the application of bionic products in real life. [0003] The current artificial muscles use pneumatic schemes, one is a cylinder and the other is a deformation chamber. The cylinder can be pushed and pulled, and the force is directly related to the air pressure. The force-to-weight ratio can reach more than 50, but the movement is slow, which cannot simulate the characteristics of the muscles that can be fast or slow, the pulling force can be large or small, and the changes are real-time. The deforming cavity is generally made of 3D printed pleated plastic. When it is inflated, it will generate pulling force or pushing force. The force end is soft and the force-...
