Abstract

The invention relates to an embedded hinge for an automobile headrest and an armrest and a manufacturing method of the embedded hinge. The embedded hinge is that the middle part of a main shaft (3) is smooth; a plurality of frictional plates (4) which are closely arranged in parallel sleeve the outer side of the smooth part; the main shaft (3) transversely passes through a housing (1); the frictional plates (4) are positioned in the housing (1) and connected with the inner sidewall of the housing (1), wherein the frictional plates (4) are in point contact connection with the main shaft (3) and rotate opposite to the main shaft (3); the housing (1) is full of lubricating oil, and end covers (3) are mounted at two ends of the housing (1) by a sealing manner. The embedded hinge has the characteristics of being simple in structure, convenient to manufacture, low in production cost, high in fatigue resisting intensity, and adjustable in torque.

Description

technical field

[0001] The invention relates to the manufacturing field of connectors for automobile headrests and armrests, in particular to an embedded hinge for automobile headrests and armrests and a manufacturing method thereof. Background technique

[0002] Hinges generally used in automobile headrests and armrests usually use imported hinges. The friction plate set used inside the hinge is generally composed of several circular friction plates stacked together. In the hinge shell, the friction plate is placed to rotate. At the same time, the friction plate group and the main shaft adopt surface contact. Although the friction force generated by the surface contact is very large, it is not conducive to the dripping of lubricating oil. After the shaft is installed, it needs to be rotated continuously. Only the rotating shaft can make the lubricating oil fill between the entire rotating shaft and the friction plate group. This kind of imported hinge is not only time-consu...
