Problems solved by technology

[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-consuming to produce and assemble, but also very expensive. Therefore, in order to reduce the overall production cost and increase the production speed, a new hinge structure is designed. is necessary

Embodiment 1

[0026] According to the torque required by the hinge, first install the friction plate 4 on the smooth position in the middle of the main shaft 2, then install the main shaft 2 in the housing 1, and then set the pressure of the press according to the required torque, and press the press together The housing 1 deforms the housing 1 and generates pressure, which causes the inner friction plate 4 to deform, so that the friction plate 4 and the main shaft 3 generate friction through point contact, which changes the torque of the hinge, and then passes through the housing The arc-shaped grooves 7 at both ends are filled with high and low temperature resistant lubricating oil, and finally sealed by the end cover 2, so that dust can enter and prevent lubricating oil from leaking.

Embodiment 2

[0028] When the hinge link needs to be installed inside the headrest, the hinge link is placed into the mold, the hinged shell 1 is installed on the headrest fixing part, and the end of the main shaft 2 corresponds to the connection position of the headrest rotating part, and then injection molding The headrest skeleton is formed by injection molding, and the entire headrest skeleton is integrally formed, wherein the connecting position of the headrest rotating part wraps the transverse groove 5 on the end of the main shaft 2 and is not easy to fall off.

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 present invention relates to the manufacturing field of automobile headrests and armrest connectors, in particular to an embedded hinge for automobile headrests and armrests and a manufacturing method thereof. Background technique [0002] Hinge joints generally used for car headrests and armrests usually adopt foreign imported hinges. The friction plate group used inside the hinge is generally composed of several circular friction plates stacked, and at the same time, there are extended strips embedded on the outside of the ring friction plates. In the hinge shell, the friction plate is placed to rotate. At the same time, the friction plate group and the main shaft are in surface contact. Although the friction force generated by the surface contact is very large, it is not conducive to the dripping of lubricating oil. The rotating shaft needs to be continuously rotated after being installed. The shaft can fill the entire shaft and friction plate with l...
