Problems solved by technology

[0006] The purpose of the present invention is to provide a follow-up mechanism, so as to solve the problem that the pressing force at the friction plate in the prior art depends entirely on the spring parameters, which makes it difficult to adjust the friction force, the diameter of the friction plate is too large, and there are many key parts, which leads to the control of dimensional accuracy. Difficult, low concentricity, and flaws that failed 30,000 fatigue tests

Embodiment Construction

[0029] Below in conjunction with accompanying drawing, provide the preferred embodiment of the present invention, and describe in detail, make can better understand the function, characteristic of the follow-up mechanism of the present invention.

[0030] Such as Figure 3-5 Shown is a follow-up mechanism according to a preferred embodiment of the present invention. The mechanism includes a mechanism base 1 and a mechanism hinge 2 connected through two rotating shafts 31 on the left and right sides respectively. The left and right are completely symmetrical structures, wherein the rotating shaft 31 is divided into two sections, one section is a flat head section with a diameter of 6mm , the other section is a round head section with a diameter of 6mm, and the middle of the flat head section and the round head section is separated by a flange 311 with a diameter of 12mm. A flat hole is opened on the mechanism base 1, and a round hole is opened on the mechanism turning page 2, ...

Abstract

The invention provides a free stopping mechanism which comprises a mechanism base and a mechanism turning leaf, wherein the mechanism base and the mechanism turning leaf are connected on one side in a penetrating mode through a revolving shaft. A flange is arranged on the revolving shaft. A first friction piece, a second friction piece and a dish cushion piece are arranged among the mechanism base, the mechanism turning leaf and the flange at intervals. The mechanism base and the mechanism turning leaf are pressed through the flange. An opening-assisting spring is wound on the periphery of the revolving shaft and connected with the mechanism base at one end and connected with the mechanism turning leaf at the other end. The diameters of the friction pieces and the outer diameter of the opening-assisting spring can be controlled within 24mm and even can reach 12mm. Pressure on the friction pieces depends on pressure of riveting equipment or screwing torque of a nut so as to facilitate adjustment. Key parts are reduced. Coaxiality and rigidity are improved to prevent the revolving shaft from axially displacing. Attenuation of the friction pieces after a high temperature and low temperature fatigue alternating test is relieved and the friction pieces can undergo thirty thousand times of fatigue tests.

Description

technical field [0001] The present invention relates to a mechanical mechanism, more particularly to a follow-up mechanism. Background technique [0002] In the field of automotive interiors, some models have an open center console armrest configuration, and the effect of opening the armrest is different. For example, some armrests need to be grasped by the user during the whole process of opening. Once they let go, they will quickly fall and close, similar to the front hood of a car; The user needs to press down with his hands. Once the hand is released, the armrest will return to the maximum opening angle, similar to the trunk lid of a car; some armrests have preset opening angles, and the user can open the armrest to these specific angles according to needs. When hovering occurs, the armrest can withstand a certain amount of pressure at a preset opening angle without closing, similar to a car handbrake; some armrests can hover at any opening angle, and will not automatic...
