Abstract: A damper with hidden rail, comprising a shell and a damper, the damper comprises a tension piece, a sliding block, a telescopic cylinder and a limiting piece, the sliding block is slidably mounted in the shell, and the tension piece is connected to the shell and the sliding block; the tension piece is capable of pulling the sliding block to move; the limiting piece is connected to the sliding block, and the telescopic cylinder is mounted on the shell; the limiting piece is provided with a compression surface, one end of telescopic cylinder abuts 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 that the tension piece pulls the sliding block, the telescopic cylinder moves; and in the process that the telescopic cylinder moves, the telescopic cylinder is gradually compressed.

Abstract: A door hinge having a damping function, comprising a housing, a first rotating shaft, a second rotating shaft, a U-shaped rotating shaft, a hinge cup, a linkage member, a torsion spring, a connector, a supporting structure, and a damping structure; one end of the linkage member is rotationally provided in the housing by means of the first rotating shaft, and the other end of the linkage member is rotationally connected to the hinge cup by means of one arm of the U-shaped rotating shaft; one end of the connector is rotationally provided in the housing by means of the second rotating shaft, and the other end of the connector is rotationally connected to the hinge cup by means of the other arm of the U-shaped rotating shaft; the torsion spring is fitted over the second rotating shaft.
