Abstract

The utility model provides a combined switch for a car, which is composed of a bearer, a handle, a knob, a control lever in the handle, etc. The utility model is characterized in that the handle and the end of the control lever are respectively provided with ashifting fork and a shifting block, and the shifting fork and shifting block can drive a slide plate embedded in a slide plate sleeve to slide; the bottom surface of the slide plate and the bearer corresponding to the bottom surface of the slide plate are provided with a movable and a fixed contact pieces, and contacts are positioned on the movable contact piece or the fixed contact piece. The contact force of the combined switch is provided by springs, the movable contact piece is regarded as an electricity conducting element, and the movable and fixed contact pieces are contracted in a slide mode, so the utility model has the characteristics of reliable contact and long service life.

Description

The automobile unit switch

The utility model relates to a kind of automobile unit switch, refers in particular to the unit switch that can be used for car bulb control.

Existing automobile generally comprises light control and windscreen wiper control two parts with unit switch, the light control section is by carriage, slide plate, reed, ejector pin, on, compositions such as lower contact, its basic structure is that reed one end is installed on the carriage, the other end is established upper contact, slide plate is positioned at the carriage below, which is provided with the logic groove, the ejector pin that reed will pass carriage is pressed on the slide plate, and position corresponding with upper contact on the carriage is provided with lower contact, before slide plate, after, a left side, during right motion, ejector pin falls into groove, the switch contact conducting, and ejector pin is opened to end face, switch contact disconnects, because reed is both as flexible member, again as conducting element, during switch on and off in the course of work, reed bears dynamic loading, be easy to generate fatigue failure, therefore this unit switch exists the life-span short, the problem of poor reliability.

For this reason, the deficiency that is to overcome prior art of the purpose of this utility model, and a kind of good reliability, long automobile unit switch of life-span are provided.

The technical scheme that realizes the utility model purpose is a kind of automobile unit switch, at least comprise switch carriage, be installed on handle and the knob that is positioned at lever operated end on the carriage, knob is by being wrapped in the break-make of the control lever control switch in the handle, its special character is that the end of control lever is provided with shifting block, shifting block can insert the draw-in groove on the slide plate that is arranged in its below, be fixed with static contact on the carriage corresponding with the slide plate bottom surface, at the bottom of the slide plate and have groove, be embedded with flexible member and movable contact spring in the groove, movable contact spring is pressed on the static contact under the flexible member effect, and the contact then is positioned on static contact or the movable contact spring.

And the control end of handle is provided with position-limit mechanism, and it is made of the spring, the ball that are positioned at the logic groove on the carriage and be mated.

And the flexible member that is arranged in groove is a spring.

Above technical scheme further is improved to slide plate peripheral hardware slide plate cover, and the slide plate cover is embedded in slide plate wherein, and the projection that slide plate puts is arranged in the shift fork that is located at the handle below.

As shown from the above technical solution, the automobile that the utility model provides uses the light control section of unit switch mainly by carriage, slide plate, spring, moving, formations such as static contact, movable contact spring is embedded in the groove of slide plate bottom surface, static contact is fixed on the carriage, movable contact spring relies on the pressure of groove inner spring to be pressed on the static contact, owing to made the reed clapper-type contact of contact in the prior art scheme contact of into contact slidingtype, contact pressure is stable, be difficult for producing fatigue failure, so long service life of this switch, and in the unit switch that the utility model provides, use movable contact spring as conducting element, sliding contact, good reliability.

The utility model is described in further detail below with reference to accompanying drawing.

Accompanying drawing 1 is a main diagrammatic sketch of the present utility model.

Fig. 2 be among Fig. 1 A-A to cut-away view.

Shown in accompanying drawing, the automobile that the utility model provides mainly is made up of light control section 12 and windscreen wiper control section 7 with unit switch, wherein windscreen wiper control section 7 adopts prior art, here no longer explain, the joystick 2 of light control section 12 is installed on the carriage 8, the operating side of handle 2 is provided with knob 1, knob 1 is installed on the control lever 3 that is wrapped in handle 2 inside, the control end below of handle 2 is provided with shift fork 17, shift fork 17 belows are slide plate cover 14, projection on the slide plate cover 14 is positioned at shift fork 17, slide plate 13 is embedded in the slide plate cover 14, the control end of control lever 3 is provided with shifting block 16, shifting block 16 is with knob 1, when control lever 3 rotates, can insert the draw-in groove 15 on the slide plate 13 that is arranged in its below, knob 1 just can be by control lever 3 shifting blocks 16 control slide plates 13 left sides like this, right is slided, 2 on handle is by before stirring slide plate cover 14 and making slide plate 13, the rear is to slip, slide plate 13 bottom surfaces have groove 18, be embedded with flexible member 11 and movable contact spring 10 in the groove 18, flexible member 11 is a spring in the present embodiment, be fixed with static contact 9 on the carriage 8 corresponding with slide plate 13 bottom surfaces, movable contact spring 10 is pressed on the static contact 9 in the effect 1 of spring 11, the contact then is positioned on static contact 9 or the movable contact spring 10, distributing position according to the contact in the utility model is provided with the logic position-limit mechanism at the control end of handle 2, this mechanism is identical with the structure of this part in the prior art, all mainly by being located at logic groove 6 on the carriage 8 and the spring 4 that is mated, ball 5 constitutes, in the operating process, slide plate 13 is at handle 2, before the common control of knob 1 down, after, a left side, right motion, drive movable contact spring 10 and carry out the logic slip, realize the break-make of switch contact, when movable contact spring 10 is connected static contact 9, switch conduction, when movable contact spring 10 breaks away from static contact 9, switch disconnects, the accompanying drawing of present embodiment provides the example with the supporting unit switch of mini van, but in actual the use according to the characteristics of other vehicle, make an amendment slightly on the basic structure of this unit switch according to conventional method, can make and the supporting unit switch of other vehicle.
