AI Technical Summary

Technical Problem

Conventional shock absorbers with springs and air cylinders require a large space due to the matching length of the air cylinder and spring, leading to an oversized slide rail, which is inefficient and costly.

Method used

A shock absorber with a hidden rail design that incorporates a telescopic cylinder, a tensioning member, and a limiting member, where the telescopic cylinder is compressed differently from the sliding direction, converting its force into resistance for damping, reducing the size and cost by eliminating the need for a long air cylinder.

Benefits of technology

The hidden rail damper achieves a damping effect while significantly reducing the size and cost of the damping structure by minimizing the space required for the air cylinder, ensuring stable and efficient operation.

Abstract

The present invention provides a concealed rail damper comprising a frame and a damper, wherein the damper comprises a tensioning piece, a sliding piece, a telescopic cylinder, and a limiting piece; the sliding piece is slidably installed in the frame, and the tensioning piece is connected to the frame and to the sliding piece; the sliding piece has a first position and a second position in the frame, and the tensioning piece is capable of pulling the sliding piece to move it from the first position to the second position; the limiting piece is connected to the sliding piece and the telescopic cylinder is installed in the frame; or the telescopic cylinder is installed in the sliding piece, and the limiting piece is installed in the frame.The limiting piece is provided with a compression surface; one end of the telescopic cylinder rests against the compression surface directly or indirectly, and the telescopic cylinder and the limiting piece have a first relative position and a second relative position. In the process where the tensioning piece pulls the sliding piece to move from the first position to the second position, the telescopic cylinder moves from the first relative position to the second relative position. And in the process where the telescopic cylinder moves from the first relative position to the second relative position, the telescopic cylinder is gradually compressed. The shock absorber provided by the present invention adopts a small-sized telescopic cylinder, thereby reducing the production cost of the shock absorber.
