Abstract

The invention relates to a buffer and an operating mechanism using the buffer. The buffer comprises a piston cavity, a piston and an electric field generating device, the outside of the piston cavity is provided with a fluid channel, two fluid inlets and outlets are arranged on the fluid channel, the two fluid inlets and outlets are communicated with a rod cavity and a non-rod cavity of the piston cavity respectively, and the electric field generating device is arranged on a channel wall of the fluid channel. When the buffer is in use, an electrorheological fluid flows among the rod cavity, the non-rod cavity and the fluid channel through the two fluid inlets and outlets on the fluid channel; the buffering stroke of the piston cannot be limited by the electric field generating device, and compared with the prior art, the buffering effect is better.

Description

technical field [0001] The invention relates to a buffer and an operating mechanism using the buffer. Background technique [0002] Most of the existing operating mechanisms are electronically controlled, and the operating speed of the operating mechanism is relatively high during the opening or closing process. In order to slow down the rigid collision of the operating mechanism, a buffer is often installed on the operating mechanism. [0003] The Chinese utility model patent with the authorized announcement number CN2318453Y and the announcement date of 1999.05.12 discloses a self-adaptive damper composed of electrorheological fluid and piezoelectric ceramics, including an outer cylinder. Guided assembly partition, the partition divides the inner cavity of the outer cylinder into upper and lower chambers, the upper chamber is equipped with a piston, and is filled with electrorheological fluid; the lower chamber is equipped with piezoelectric ceramic sheets, piezoelectric c...
