AI Technical Summary

Technical Problem

The reaction force of the existing buffer sheet increases sharply during compression, resulting in the inability to stabilize the desired reaction force in some cases.

Method used

A buffer sheet is designed, which includes a flat plate portion and a plurality of protrusions, with a hollow inside the protrusion, and a groove is provided on the inner and outer surfaces of the protrusion, and the groove is deformed in a stable posture as a starting point for deformation.

Benefits of technology

By providing the groove, the protrusion can be deformed stably during compression, and a large change in reaction force is suppressed, so as to ensure that the buffer sheet can stably generate the desired reaction force.

Abstract

The invention provides a buffer sheet capable of stably generating a reaction force. The buffer sheet (100) is composed of an elastic body and comprises: a flat plate part (110); the buffer sheet (100) is provided with a flat plate section (110), and a plurality of protruding sections (120) protruding from the flat plate section (110), the inside of each protruding section being a cavity opening on the opposite side in the protruding direction, the buffer sheet being characterized in that a groove is provided on at least one of the inner surface and the outer surface of each protruding section (120), the groove being a deformation starting point when the protruding section (120) is compressed and deformed.
