Embodiment Construction

[0039] like Figure 1 to Figure 3 As shown, the structure of the damping device 100 includes a cage 110 , a mandrel 120 , a friction bush 130 , a compression spring 140 and a screw 150 . The cage 110 is used to support the mandrel 120 , the friction bearing shell 130 , the compression spring 140 and the screw 150 .

[0040] The cage 110 is cylindrical and is provided with a first accommodating hole 111 and a second accommodating hole 112 . The first accommodating hole 111 penetrates through the cage 110 in the axial direction. The second accommodating hole 112 is radially extended on the holder 110 and has an opening on the side wall 113 of the holder 110 . The first receiving hole 111 communicates with the second receiving hole 112 . There are a plurality of second accommodation holes 112 uniformly distributed along the circumferential direction, and the specific number can be determined according to the number of compression springs 140 to be provided.

Abstract

The invention relates to a damping device. The damping device comprises a retainer, a mandrel, friction bearing bushes, elastic reset devices and abutting pieces; the retainer is provided with a first accommodating hole and second accommodating holes, and the first accommodating hole is communicated with the second accommodating holes; the mandrel is partially inserted into the first accommodating hole and is movably arranged; the friction bearing bushes are used for providing friction force to serve as resistance for rotation of the mandrel, and the elastic reset devices abut against the friction bearing bushes; and the abutting pieces are arranged in the second accommodating holes, and the abutting pieces abut against the elastic reset devices so that the elastic reset devices can keep abutting against the friction bearing bushes. The damping device is simple in structure and low in production cost. All parts of the damping device can be fed by adopting an automatic feeding machine and can be automatically assembled by adopting automatic production equipment, so that the labor intensity of workers is reduced, and the production efficiency is high.

Description

technical field [0001] The present invention relates to damping devices. Background technique [0002] At present, the electric tailgate technology is the latest technology for the trunk tailgate of passenger cars, especially SUV and MPV models. Object sensing operation, the device that controls the opening and closing of the tailgate, and the electric tailgate also has functions such as intelligent anti-pinch and height memory function. It has the advantages of convenient control and strong practicability, so it is widely used in C-class luxury cars and B-class vehicles, such as Land Rover Evoque, Range Rover series, Ford Maverick, Volvo XC70 and other SUV models. [0003] In order to ensure the realization of the various functions of the electric tailgate, it is necessary to be equipped with anti-pinch strips, self-priming locks, ECU and electric struts. The reciprocating movement of the electric struts is controlled by the ECU, combined with the assistance of self-primin...
