Embodiment Construction

[0020] Embodiment: a kind of two-way mechanical friction damper, comprises piston cylinder 1, piston rod 2, piston and elastic body 3, and described piston rod 2 axially can slide setting distance and is inserted in piston cylinder 1, and piston rod 2 One end that is always located in the piston cylinder 1 is provided with a piston, and at least one elastic body 3 is arranged on the outer wall of the piston circumference, and the elastic body 3 is elastically pressed against the inner surface of the piston cylinder 1. The working principle: the elastic body 3 is installed in the piston cylinder 1 At this time, the elastic body 3 has a certain positive pressure on the inner wall of the piston cylinder 1. When the piston rod 2 is pulled and pressed, a certain frictional resistance will be generated between the elastic body 3 and the inner wall of the piston cylinder 1. The direction of the frictional resistance is opposite to the movement direction of the piston rod 2, and its si...

Abstract

The invention discloses a two-way mechanical friction damper, which includes a piston cylinder, a piston rod, a piston and an elastic body. The piston rod can slide axially and is inserted in the piston cylinder at a set distance, and the piston rod is always located in the piston cylinder. One end of the piston is provided with a piston, and at least one elastic body is provided on the outer wall of the piston circumference. When it is used to hover the luggage door of a car, it can stop the opening of the luggage door at any customary position. The mechanism has a simple structure, low manufacturing cost, does not need to be inflated, has no sealing requirements, and is not affected by temperature.

Description

technical field [0001] The invention relates to an automobile luggage door strut, in particular to a two-way mechanical friction damper. Background technique [0002] At present, the gas springs with arbitrary stop function are mainly used in the luggage door struts of automobiles. However, the gas springs have the following disadvantages: [0003] 1. It needs to be inflated, and has high requirements for airtightness. The airtightness is also affected by temperature. Due to thermal expansion and contraction, it will have sealing problems, resulting in the inability to hover at any position normally; [0004] 2. The traditional arbitrary gas stop spring has complex structure and high manufacturing cost. Contents of the invention [0005] In order to make up for the above deficiencies, the present invention provides a two-way mechanical friction damper, the two-way mechanical friction damper has a simple structure, low manufacturing cost, no need to inflate, no sealing req...
