Automobile is with the combination shifting part structure of stirring unit switchTechnical field
The utility model relates to a kind of automobile with the combination shifting part structure of stirring unit switch, belongs to the unit switch technical field.
Background technology
All be equipped with in the left and right sides of vehicle steering and stir unit switch; Stir unit switch multiple stroke action is in use arranged; Signal lamp when turning to like control; Continuous near, distance light when overtake other vehicles night switch, and wherein above-mentioned some step all requires to stir unit switch and has auto-reset function.It is through the completion that cooperatively interacts of shifting part, spring, ejector pin, waveform tooth that existing unit switch is accomplished the work that resets, and wherein on shifting part, offers two spring eyes, in spring eye, is placed with spring and ejector pin; Ejector pin is pressed on the waveform tooth, and in the process of shifting part motion, ejector pin slides between the crest of waveform tooth and trough; When shifting part was stressed, ejector pin slided to crest from trough, and this moment, spring deformation was maximum; After loosing one's grip, the ejector pin self-return is to trough under the elastic force effect.But the phenomenon that driving lever can not self-return takes place in the unit switch regular meeting of stirring that in use finds existing this structure; Also there is the lighter problem of feel in the existing unit switch of stirring simultaneously.
Summary of the invention
The technical problem that the utility model will solve is, provide a kind of self-return sensitive, accurately, stir the suitable automobile of feel with the combination shifting part structure of stirring unit switch, can overcome the deficiency of prior art.
The technical scheme of the utility model is: it comprises shifting part, ejector pin, spring and waveform tooth; On shifting part, offer left spring hole and right spring eye; In left spring hole and right spring eye, be respectively equipped with spring and ejector pin; The end of ejector pin contacts with the flank of tooth of waveform tooth, and left spring hole and right spring eye are positioned at the both sides and the asymmetric arrangement of shifting part center line.
The distance of the center line in left spring hole and shifting part center line is 9.8mm, and the distance of the center line of right spring eye and shifting part center line is 10.3mm.
The degree of depth in left spring hole is 17.5-18.5mm, and the degree of depth of right spring eye is 15.5-16.5mm.
With prior art relatively, the utility model so just can avoid two ejector pins to be positioned at crest simultaneously and to be in poised state the spring eye asymmetric arrangement of shifting part center line both sides, can well solve driving lever can not the self-return problem; The degree of depth of spring eye is slightly transferred shallow, so just can increase the deflection of spring, solve the light problem of feel of stirring.

Embodiment
Embodiment 1: as shown in Figure 1; On shifting part 1, offer left spring hole 4 and right spring eye 5, in left spring hole 4 and right spring eye 5, be respectively equipped with spring and ejector pin 2, the half the circumference of the sleeve where it joins the shoulder of ejector pin 2 is pressed in Spring Card in the spring eye; The end of ejector pin 2 contacts with the flank of tooth of waveform tooth 3; For the end of avoiding ejector pin 2 is positioned at the crest of waveform tooth 3 simultaneously, when making shifting part 1, will be positioned at the left spring hole 4 and right spring eye 5 asymmetric arrangement of the both sides of shifting part 1 center line; It specifically is of a size of the center line in left spring hole 4 and the distance of shifting part 1 center line is 9.8mm, and the distance of the center line of right spring eye 5 and shifting part 1 center line is 10.3mm.Simultaneously for solving the light problem of driving lever feel; The degree of depth of left spring hole 4 and right spring eye 5 is reduced; The degree of depth that specifically is of a size of left spring hole 4 is 17.5-18.5mm, and the degree of depth of right spring eye 5 is 15.5-16.5mm, and its degree of depth begins to measure from the top of shifting part (1).Solving the light problem of feel also can adopt the replacing spring to realize.
