A voice coil actuated miniature flexible valve

Abstract

The invention discloses a minisize flexible valve driven by a voice coil. The minisize flexible valve comprises two parts, namely a driving valve and a follow-up valve. An upper film is arranged on the upper surface of a driving valve upper valve body in a covering manner. A lower film is arranged between the driving valve upper valve body and a driving valve lower valve body. The driving valve upper valve body is provided with a horizontal ventilation pipe and a vertical valve hole. A sliding block is mounted in the valve hole and slides up and down. The ventilation pipe is cut off into two parts through the sliding block, and the two parts communicate with each other through a driving valve control gas channel. The driving valve lower valve body is provided with a valve cavity. The valvecavity is internally provided with a voice coil boss and a coil. Magnetic steel is located at the bottom. The coil is connected with a power source through a wire. A follow-up valve upper valve bodyis provided with a horizontal gas channel. A follow-up valve gas inlet / outlet communicates with gas through an extrusion channel. A follow-up valve lower valve body is provided with the horizontal gaschannel to serve as a follow-up valve control gas channel, wherein the follow-up valve control gas channel extends to the position under the extrusion channel and penetrates the upper top face. The follow-up valve control gas channel is connected with a driving valve gas outlet. The minisize flexible valve is good in compatibility with a soft robot and high in external impact resistance, and adaptability of the valve is improved.

Description

technical field [0001] The invention relates to a flexible valve, in particular to a micro flexible valve driven by a voice coil, which is used to control the movement of a pneumatic soft robot. Background technique [0002] In recent years, traditional solenoid valves are made of metal materials, which are relatively hard and difficult to integrate on soft robots. Moreover, these solenoid valves made of hard materials are easily damaged under harsh environmental conditions or after being impacted. In view of the above problems, it is necessary to study a new type of micro-flexible valve driven by voice coil to solve these problems. Contents of the invention [0003] In order to solve the problems existing in the background technology, the object of the present invention is to provide a brand-new micro-flexible valve driven by a voice coil, which is used to control the motion of a pneumatic soft robot. [0004] The technical scheme adopted in the present invention is: ...
