Embodiment Construction

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0030] see Figure 1 to Figure 3 A self-pretensioning rotating shaft assembly shown includes a bushing 100 , a torsion spring assembly center shaft 200 , a first fixing block 300 , a torsion spring 400 , a buffer sleeve 500 and an elastic buffer washer 600 .

[0031] The casing 100 in this embodiment is an aluminum tube, and an axial notch 101 , 102 is formed on the outer surface of both ends of the casing 100 . The central shaft 200 of the torsion spring assembly is arranged in the casing 100, and the central shaft 200 of the torsion spring assembly is preferably a steel shaft.

[0032] A flattened head 210 is processed at the front end of the central axis 200 of the torsion spring assembly, a pair of ear portions 220 are arranged near the front end, and a collar 230 is set betwe...

Abstract

The invention discloses a self pre-tightening force rotating shaft component, comprising a sleeve, a torsion spring assembly center shaft, a first fixed block arranged at a first end of the sleeve, a torsion spring and a cushion cover sheathing between the outer peripheral surface of the torsion spring and the inner wall of the sleeve, wherein the diameter of the tail end of the torsion spring is gradually reduced and finally close to the outer diameter of the torsion spring assembly center shaft, the tail end of the torsion spring is set to be a hook-like structure, a pin hole is formed at a position close to the tail end of the torsion spring assembly center shaft, a pin passing through the pin hole is matched with the hook-like structure to fix the tail end of the torsion spring, one elastic buffer washer in interference fit with the inner wall of the sleeve sheathes between the tail end of the torsion spring assembly center shaft and the pin hole, and the two ends of the elastic buffer washer are limited by the pin and a locking piece arranged at the tail end of the torsion spring assembly center shaft. The self pre-tightening force rotating shaft component can prevent the torsion spring and the sleeve from being in contact to produce noise in a bumping or jittering environment, and functions of buffering and damping are achieved.

Description

technical field [0001] The invention relates to a rotating shaft assembly, in particular to a self-pretensioning rotating shaft assembly suitable for a window rotating shaft (such as an automobile sunroof rotating shaft, a high-speed rail window rotating shaft, etc.). Background technique [0002] The structure of the current energy storage rotating shaft mechanism is roughly like the energy storage mechanism disclosed in the background technology of the Chinese patent authorization announcement number CN203584283U (authorization announcement date 2014.05.07). However, the end of the torsion spring of the energy storage mechanism of this structure is a diameter-shaped torsion arm, which is placed in the slot at the tail of the iron core. It is necessary to assemble a blocking sleeve and then put on a snap ring, which is complicated to assemble. And the noise reduction effect of the energy storage mechanism of this structure is poor.
