Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile split central armrests, and in particular relates to a rotating shaft structure suitable for an automobile flip central armrest. Background Art
[0002] At present, many central armrests of the central control sub-panel of automobiles are designed to be flip-up. Compared with the double-leaf armrest, the rotating shaft mechanism of the flip-up central armrest plays a vital role. The current rotating shaft is designed as a ratchet and ratchet form. Due to structural limitations, problems such as jamming, noise, and gear loss are very likely to occur during operation. In view of this, a rotating shaft structure suitable for a flip central armrest of an automobile is urgently needed in the industry. The matching structure of the screw torque and the end face teeth is utilized to avoid the jamming, noise, and gear loss caused by the ratchet and ratchet structure. Utility Model Content
[0003] The purpose of the utility model is to provide a rotating shaft structure suitable for a flip central armrest of an automobile, which plays the role of a rotating shaft by utilizing the torque of a screw and the cooperation between the end teeth, thereby solving the problems of jamming, gear loss, and gear breaking caused by the existing ratchet wheel and ratchet gear rotating shaft cooperation.
[0004] The utility model solves the technical problem by adopting the following technical solutions:
[0005] A rotating shaft structure suitable for a flip central armrest of an automobile, comprising: a bracket body 1, a hinge bracket 2, a ring nut 3, a damper 4, a swing arm 5, a gasket 6, a disc gasket 7, and a fastening screw 8, wherein the swing arm 5 is coaxially matched with the bracket body 1; the hinge bracket 2 is coaxially matched with the damper 4, and the shaft on the ring nut 3 passes through the holes on the hinge bracket 2 and the ring nut 3; the boss A on the damper 4 is matched with the groove B on the bracket body 1; the shaft on the ring nut 3 is coaxially matched with the hole on the damper 4, and the end face tooth shape of the ring nut 3 is It meshes with the end face teeth of the damper 4; the shaft on the ring nut 3 passes through the holes on the hinge bracket 2, the damper 4, the swing arm 5 and the bracket body 1 and passes through the disc gasket 7 and the gasket 6 with the fastening screw 8, and the ring nut 3 is fixed with the fastening screw 8 by threaded connection; after assembly, the damper 4 cooperates with the end face teeth of the ring nut 3, and the fastening screw 8 is tightened by torque, and the disc gasket 7 is subjected to force. During the flipping process of the armrest, the end face teeth of the damper 4 provide a reverse force when the armrest is flipped, and the butterfly gasket 7 will also balance part of the force and provide an extrusion force equal to the torque.
[0006] The advantages and positive effects of the utility model are:
[0007] In this new design, the damper is installed on the bracket body and fixed, and the end face tooth profile of the damper meshes with the damper teeth, providing a rotation axis for the central armrest under the action of the tightening torque. This design can ensure the stability of the armrest during use and prevent driving safety and comfort from being affected by the unstable mechanical structure of the armrest.
