Abstract

The utility model relates to a vehicle lamp switch, mounted in vehicle lamp, between a light source and a front frame, to control the extension of an extend rod via an electromagnetic valve, thereby moving a mobile plate to selectively shade part of the light source. And when the mobile plate shades part of the light source, the light strength is weak to be used as near lamp, and when the mobile plate not shades the light source, all light rays can be radiated outward, the light strength is strong to be used as far lamp. Therefore, the utility model can use single light source and simple structure to switch near lamp and far lamp, to effectively reduce production cost and assemble process.

Description

The car light shifter

Technical field

The utility model is a kind of car light shifter, refers to a kind of being located in the car light, in order to change the shifter of far and near lamp.

Background technology

Vehicle is when night running, because weather, the factor that road conditions etc. are different, need utilize of the illumination of different light as vehicle front, the headlight that generally is used for vehicle front is divided into lamp far away and two kinds of lighting systems of low beam at least, in the prior art, mostly adopt the mode of two light sources, promptly in same light fixture, be provided with a low beam light source and a lamp source far away, utilize and switch the whether luminous of two light sources, change the illumination of headlight as lamp far away or low beam, yet, must in same light fixture, be provided with two light sources in the prior art constructions, higher on the cost of manufacture compared to single light source, and in order to switch two light sources, many corresponding circuits must be set, increase cost of manufacture equally and improved the degree of difficulty in the assembling.

Summary of the invention

Because the shortcoming of aforesaid prior art, the utility model has designed a kind of car light shifter, utilizes single light source can reach the effect of switching far and near lamp.

For reaching above-mentioned utility model purpose, the technological means that the utility model adopted is a kind of car light shifter of design, comprising:

One base plate, one side indent form the central authorities shallow groove in dark two ends;

One portable plate, it is hubbed on the base plate, and portable plate is with respect to groove, and portable plate is provided with a plate;

One electromagnetic valve group, it has an electromagnetic valve and an extension rod, and electromagnetic valve is fixedly arranged on the base plate, and extension rod stretches out and interfixes with connecting panel from electromagnetic valve one end.

The utility model is installed in the car light, and is arranged between the light source and preceding end housing of car light, and the inner casing of base plate and car light interfixes, and the groove of base plate and portable plate are with respect to light source.

Utilize electromagnetic valve to drive extension rod, make portable plate move with respect to base plate, then portable plate optionally partly covers the light source of car light, since light source when partly being covered light intensity relatively a little less than, the distance that can throw is shorter relatively, so can be used as low beam uses, light source not during crested light intensity stronger relatively, the distance that can throw is longer relatively, uses so can be used as lamp far away, therefore, advantage of the present utility model is, utilizes simple member to form and single light source, can reach the effect of switching far and near lamp, not only cost of manufacture be can effectively reduce, assembling and production process also can be simplified simultaneously.

The specific embodiment

See also shown in Fig. 1-2, the utility model includes a base plate 10, a portable plate 20, reaches an electromagnetic valve group 30.

Aforesaid base plate 10 1 sides central authorities indent forms a groove 11, and groove 11 is central authorities' shallow shape in dark two ends, and an end that approaches to be provided with groove 11 sides on the base plate 10 runs through and forms a pivoted hole 12, and base plate 10 central authorities run through and form plurality of fixed hole 13.

Aforesaid portable plate 20 is hubbed on the base plate 10, and can cover the groove 11 of base plate 10 relatively, portable plate 20 1 ends run through and form a pivoted hole 21, one articulated part 22 runs through the pivoted hole 21 of base plate 10 and portable plate 20, so that portable plate 20 is hubbed on the base plate 10, articulated part 22 can be the combination of bolt 221 and nut 222, portable plate 20 central vertical are provided with a plate 23, connecting panel 23 can interfix with portable plate 20 or be one-body molded with portable plate 20, and connecting panel 23 forms a short slot 231 from a side indent.

Aforesaid electromagnetic valve group 30 is located on the base plate 10 and with portable plate 20 and is joined, electromagnetic valve group 30 includes an electromagnetic valve 31 and an extension rod 32, electromagnetic valve 31 is fixedly arranged on the centre on the base plate 10, electromagnetic valve 31 and the base plate 10 side indent of joining forms the plurality of fixed hole, plurality of fixed part 311 runs through the fixed orifice 13 of base plate 10 respectively and is fixed in the fixed orifice of electromagnetic valve 31, interfix with base plate 10 with electromagnetic valve 31 electromagnetic valve group 30, the fixed orifice of electromagnetic valve 31 can be screw, connecting element 311 can be screw, extension rod 32 stretches out from electromagnetic valve 31 1 ends, extension rod 32 is with respect to the groove 11 of base plate 10, and extension rod 32 interfixes with connecting panel 23, extension rod 32 directly concaves near the end and forms a ring groove 321, the ring groove 321 of extension rod 32 is embedded in the short slot 231 of connecting panel 23, so that extension rod 32 and connecting panel 23 are interfixed.

See also shown in Figure 3ly, the utility model is installed in the car light 40, and is arranged between the light source 41 and shell 42 of car light 40, and base plate 10 interfixes with the inner casing 43 of car light 40, and the groove 11 of base plate 10 and portable plate 20 are with respect to light source 41.

See also shown in Fig. 3-4, when startup electromagnetic valve 31 stretches out extension rod 32, extension rod 32 promotes connecting panel 23, make portable plate 20 cover on the groove 11 of base plate 10 relatively and shaded portions light source 41, because when light source 41 was partly covered, the light amount of outwards being throwed reduced, then light intensity weakens, so the distance that light can transmit is shorter relatively, and can be used as low beam and use this moment.

See also Fig. 3 and shown in Figure 5, when startup electromagnetic valve 31 inwardly shrinks extension rod 32, extension rod 32 pulling connecting panels 23, make portable plate 20 move and not be shielded in relatively on the groove 11 of base plate 10 to electromagnetic valve 31, because light source 41 is not masked, and then can fully outwards throw, light intensity strengthens relatively, so the distance that light can transmit is far away relatively, and can be used as lamp far away and use this moment.
