Description
Technical field
The utility model relates to a kind of motor turning switch automatic resetting device.
Background technology
The motor turning switch is a switch of realizing vehicle operation steering indicating light function when turning.Before being turn inside diameter, navigating mate operation pole changer is opened turning indicator; Behind turn inside diameter, pole changer can SELF CL, thereby closes turning indicator.
And in order to realize the self-return action of pole changer, realize by the direct or indirect bonded assembly parts of bearing circle usually.Wherein a kind of structure comprises pole changer, drive element, spring and base.With Fig. 1, Fig. 2 is the principle of work of this structure of example brief description.
Conventional confguration generally includes several sections such as drive element 10, spring 11, base 12, pole changer 13.Pole changer 13 is assemblied on the base 12, is fixing assembling.Drive element 10 is assembled on the center shaft of base 12, and spring 11 is assemblied between drive element 10 and the base 12.Under the virgin state, the buckle of drive element 10 contacts with step on the base 12, deviates from from base 12 to limit it.After switch was assembled on the vehicle, drive element 10 can move downward certain distance along base 12 central axis direction compression springs 11, and at this moment the buckle of drive element 10 separates with step on the base 12.When bearing circle rotated, drive element 10 rotated simultaneously, thereby reaches the effect of stirring return piece 14 on the pole changer, makes the switch SELF CL.
This traditional mounting structure can realize easily that drive element freely rotates with bearing circle, has advantages such as simple in structure, reliable in action.But under many situations, there are decentraction in entrucking rear base center shaft and steering column (being the bearing circle center of turn).At this moment, because suffered spring force bearing surface of drive element and bearing circle distance are bigger, bigger moment will be formed.Drive element and seat are bigger, will produce bigger friction force.Therefore, cause clamping stagnation in the drive element rotation process easily, parts depreciation is serious, and noise is bigger, thereby influences the service life of parts.
The utility model content
Technical problem to be solved in the utility model provides a kind of motor turning switch automatic resetting device.
In order to address the above problem, the utility model is taked following technical scheme:
A kind of motor turning switch automatic resetting device, it comprises pole changer, drive element, spring and base, described pole changer is assemblied on the base, be fixing assembling, described drive element is assembled on the center shaft of base, clamping between described drive element and the base, cooperatively interact, described spring is assemblied between drive element and the base, and spring housing is outside drive element, and the upper end props up the upper surface of drive element, the lower end props up base, there are two sections inclined-planes in the fitting surface of spring and drive element on the top of drive element on the basifacial drive element of the cooperation of described drive element and base, terminal bevel angle is 1 °.
Preferably, described drive element inwall is provided with step, and the center shaft of base is provided with buckle, and step and buckle clamping make described drive element and base be connected together by this structure.
Preferably, be provided with the cooperation muscle in a side of the spacing buckle of described base, described drive element cooperates with the muscle that cooperates on the base.
Preferably, described drive element and base matching part are facing directly of 2mm.
The beneficial effects of the utility model are: when drive element moved with bearing circle, if the center shaft of base and steering column decentraction, drive element can be done coning motion around the base center shaft.When the handle of pole changer is got to out, the return piece will stretch out to base central hub direction on the pole changer.Like this, when drive element rotates, can activate return piece on the pole changer.The mounting structure of drive element and base center shaft, realizing that drive element is when the center shaft of base is done coning motion, and because the spring bearing surface is on the top of drive element, reduce moment of torsion, thereby reduce friction, make the drive element motion reliable, flexible, thereby reach the function of return piece on the smooth and easy activation pole changer.

The specific embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Shown in Fig. 3,4,7, motor turning switch 23 automatic resetting devices of the present utility model, it comprises pole changer 23, drive element 20, spring 21 and base 22.Described pole changer 23 is assemblied on the base 22, be fixing assembling, there is the cylindrical center axle at base 22 centers, drive element 20 is assemblied on the center shaft of base 22, spring 21 is assemblied between drive element 20 and the base 22, and drive element 20 is cylindrical, and the inwall of drive element 20 is provided with step, buckle 26 is arranged on the center shaft of base 22, and drive element 20 and base 22 are by step and buckle 26 spacing clampings.Because spring 21 is when virgin state, the step at drive element 20 middle parts contacts with buckle 26 on the base 22 all the time.As shown in Figure 4, spring 21 mainly is enclosed within outside the drive element 20, and the assembling back mainly cooperates with drive element 20, and the upper end of spring 21 props up the top of drive element 20, and the plane of action that makes spring 21 is on the top of drive element 20, and the lower end of spring 21 props up base 22.Drive element 20 is 2mm with base 22 fitting surface broadbands, and this numerical value also can suitably be adjusted according to actual conditions.The fitting surface bottom of described drive element 20 and spring 21, there are two sections inclined-planes in drive element 20, and angle at the end is 1 °, and this angle also can be adjusted 3 °～5 ° according to actual conditions.Like this, when drive element 20 moved with bearing circle, if the center shaft of base 22 and steering column decentraction, drive element 20 can be done coning motion around base 22 center shafts.
As shown in Figure 5, when the handle of pole changer 23 is got to out, return piece 24 will stretch out to base 22 central hub directions on the pole changer 23.Like this, when drive element 20 rotates, can activate return piece 24 on the pole changer 23.The mounting structure of drive element 20 and base 22 center shafts, realizing that drive element 20 is when the center shaft of base 22 is done coning motion, and because spring 21 bearing surfaces are on the top (as shown in Figure 4) of drive element 20, reduce moment of torsion, thereby reduce friction, make drive element 20 motions reliable, flexible, thereby reach the function of return piece 24 on the smooth and easy activation pole changer 23.
As shown in Figure 5, be provided with bar in a side of the spacing buckle 26 of described base 22 and cooperate muscle 25, join with muscle for 8 on the internal diameter of described drive element 20 and the base 22 and cooperate.As shown in Figure 6, cooperate muscle 25 concrete structures on the base 22, this muscle position requires not have draft angle, and the high polishing in surface.On the base 22 buckle 26 concrete structures as shown in Figure 6, its moulding is finished inserting by bottom fluting, has avoided the die life loss that the strong demoulding causes and the increase of die cost like this.
This mounting structure can realize that drive element 20 does coning motion around base 22 center shafts, and since spring 21 bearing surfaces on the top of drive element 20, reduce moment of torsion, thereby reduce friction.Make drive element 20 motions reliable, flexible, thereby reach the function of return piece 24 on the smooth and easy activation pole changer 23.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
