Detailed Description

The sliding mechanism of the automobile steering system with the conductive function comprises a spline shaft 1, a conductive elastic sheet 2 and a spline sleeve 3 (see the attached figure 1 in the specification); the spline shaft 1, the conductive elastic sheet 2 and the spline sleeve 3 are all made of metal conductive materials.

A plastic isolation layer (not shown in the attached figures of the specification) is coated on the circumferential surface of one end of the spline shaft 1; the plastic isolation layer wraps and covers all spline teeth of the spline shaft 1. The purpose of setting up the plastics isolation layer lies in: so that the spline shaft 1 and the spline sleeve 3 keep a micro interference fit clearance through a plastic isolation layer, thereby solving the problem that abnormal sound and sliding are easy to occur between the existing spline shaft and the spline sleeve.

A clamping ring groove 4 is arranged on the circumferential surface of one end of the spline shaft 1; the clamping ring groove 4 is positioned on one side of the plastic isolation layer, so that the problem that the clamping ring groove 4 is difficult to conduct electricity when covering the plastic isolation layer can be avoided.

One end of the spline shaft 1 is provided with a conductive elastic sheet 2 through a clamping ring groove 4 (see the attached figures 4 and 5 in the specification). The conductive elastic sheet 2 is of an integrated structure and comprises a connecting ring 5, a butting elastic sheet 6 and a clamping claw 7; a plurality of contact spring pieces 6 are uniformly distributed on one side of the connecting ring 5 in a circular ring shape. The number of the abutting elastic sheets 6 is consistent with that of the spline grooves on the spline shaft 1, and the relative positions of the abutting elastic sheets 6 are consistent with that of the spline grooves on the spline shaft 1. Conflict shell fragment 6 can be connected with the spline groove joint on the integral key shaft 1 when so can ensure the assembly.

Conflict shell fragment 6 is bow-shaped structure, will conflict shell fragment 6 so set up's aim at: so that when the spline shaft 1 is inserted into the spline sleeve 3, the abutting elastic sheet 6 can be elastically contacted with the inner surface of the spline groove of the spline sleeve 3 through the arch back position (see the attached figures 6 and 7 in the specification). Thereby, the purpose that the spline sleeve 3 can be electrically connected with the abutting elastic sheet 6 is achieved.

A plurality of clamping claws 7 with V-shaped structures are uniformly distributed on the other side of the connecting ring 5 in a circular ring shape; the clamping claw 7 is connected with the clamping ring groove 4 of the spline shaft 1 in a clamping mode. The clamping claw 7 is arranged in such a way that the spline shaft 1 can be electrically connected with the clamping claw 7 through the clamping ring groove 4; secondly, the conductive elastic sheet 2 can be in clamping connection with the clamping ring groove 4 through the clamping claw 7, so that the problem that the conductive elastic sheet 2 is easily separated from the clamping ring groove 4 is solved.
