Referring to fig. 1-4, a clock spring shifting block 1 according to an embodiment of the present application is described, where the clock spring shifting block 1 has a small friction force when being engaged with a return latch 2, and the clock spring shifting block 1 is less worn during rotation of a steering wheel, which is beneficial for long-term use.

As shown in fig. 1 to 4, a clock spring dial 1 according to an embodiment of the present application includes: the shifting block body 11.

As shown in FIG. 1, the dial body 11 is adapted to be rotatably mounted to the vehicle body, and the dial body 11 is adapted to be interlocked with the steering wheel, so that the dial body 11 can rotate together with the steering wheel during rotation of the steering wheel. Wherein, shifting block body 11 is used for mutually supporting with steering switch's return spring bolt 2 to realize steering switch's return operation. And when the shifting block body 11 rotates to different positions, the matching state of the shifting block body 11 and the return bolt 2 of the steering switch is different.

The periphery wall of the shifting block body 11 is provided with a pressing part 12 protruding outwards along the radial direction, the return bolt 2 of the steering switch is suitable for elastically pressing a first arc-shaped surface 13 of the periphery wall of the pressing part 12, and the first arc-shaped surface is inwards recessed along the radial direction of the shifting block body.

It should be noted that the return bolt 2 of the steering switch is movably mounted on the vehicle body, wherein the return bolt 2 is elastically connected to the vehicle body through a pre-tightening spring, and after the steering switch is turned on, the return bolt 2 extends out under the elastic acting force of the pre-tightening spring.

As shown in fig. 2, the reset bolt 2 of the steering switch is opposite to the pressing portion 12 of the shifting block body 11 along the radial direction of the shifting block body 11, wherein the shifting block body 11 is configured such that, at an initial position, the pressing portion 12 of the shifting block body 11 is opposite to the reset bolt 2, and the central position of the first arc-shaped surface 13 along the circumferential direction of the shifting block body 11 is opposite to the reset bolt 2. The initial position is a position where the dial body 11 is located when the steering wheel is not rotated (the wheel is in a return state).

Thus, after the steering switch is turned on, the return bolt 2 extends out towards the shifting block body 11 under the elastic acting force of the pre-tightening spring, at the moment, the return bolt 2 is opposite to the first arc-shaped surface 13, and the first arc-shaped surface 13 is inwards recessed along the radial direction, so that the positive abutting pressure between the return bolt 2 and the first arc-shaped surface 13 is smaller or no positive abutting pressure exists, at the moment, if a driver drives the steering wheel to rotate, the friction between the abutting portion 12 and the return bolt 2 is smaller, and in the rotating process of the steering wheel, the abrasion of the abutting portion 12 is smaller.

Like this, through the cooperation of the shifting block body 11 that such structure set up with return spring bolt 2, can make shifting block body 11 still can keep good user state after long-term the use, and then guarantee to guarantee that shifting block body 11 drives return spring bolt 2 motion effectively and makes change direction switch close when the steering wheel reversal, improve the reliability that clock spring shifting block 1 used, increase of service life.

It should be noted that the axis of the second arc-shaped surface 14 coincides with the axis of the shifting block body 11, so that in the process that the return bolt 2 abuts against the second arc-shaped surface 14, the positive abutting pressure of the return bolt 2 at each position on the second arc-shaped surface 14 is the same, and it should be noted that the length of the second arc-shaped surface 14 along the circumferential direction of the shifting block body 11 is smaller than the length of the first arc-shaped surface 13 along the circumferential direction of the shifting block body 11. That is to say, in the process of the rotation of the shifting block body 11, the return bolt 2 is more opposite to the first arc-shaped surface 13. Like this, at the in-process of setting aside block body 11 for the motion of return spring bolt 2, return spring bolt 2 and setting aside block body 11 more keep at less positive pressure state, like this, can greatly reduce the wearing and tearing volume of setting aside block body 11 in the rotation process, prolong the life of setting aside block body 11.

Wherein, the curvature radius of first arcwall face 13 is the same with the curvature radius of second arcwall face 14, and like this, first arcwall face 13 and second arcwall face 14 can the same processing mode machine-shaping, improve machining efficiency, do benefit to the processing cost who reduces shifting block body 11.

In some embodiments, as shown in fig. 1, the distances from both ends of the pressing portion 12 in the circumferential direction to the axis of the first arc-shaped surface 13 are equal, that is, the central position of the first arc-shaped surface 13 in the circumferential direction of the shifting block body 11 coincides with the central position of the pressing portion 12, so that when the shifting block body 11 rotates clockwise and counterclockwise, the pressing states of the return bolt 2 and the first arc-shaped surface 13 are the same, thereby ensuring that the vehicle can be accurately and reliably aligned when turning left or right.

In some embodiments, as shown in fig. 1 to fig. 3, there are two pressing portions 12, the first arc-shaped surfaces 13 of the two pressing portions 12 are disposed opposite to each other in the radial direction of the shift block body 11, and both the two pressing portions 12 can be used to cooperate with the return bolt 2. Therefore, when the abrasion loss of one of the pressing parts 12 is large, the position of the shifting block body 11 can be flexibly adjusted, so that the other pressing part 12 is matched with the return bolt 2, the clock spring shifting block 1 does not need to be replaced when one of the pressing parts 12 is damaged, and the use cost of the clock spring shifting block 1 is reduced.
