Technical field
The utility model relates to the nearly distance light adjusting device of a kind of car light.
Background technology
At present, on the vehicle night employed headlamp, according to different driving road-condition lighting requirements, need have the function of switching high beam, dipped headlights.Common headlamp is in order to take into account the irradiates light shape of nearly distance light, and the design of its light distributing system is very complicated, and the shape of car light is subjected to the restriction of car shape again.The headlamp of more existing vehicles is made of a light source and speculum, in order to form two kinds of different irradiates light shapes according to the world, adopt the form of an anti-dazzling screen to finish the conversion of far changing light, but the light-shielding structure of more existing conversion light shapes, in order to satisfy the performance indications that become the light time, its structure more complicated has reduced the cost that reliability has increased product simultaneously.
The utility model content
The purpose of this utility model is: provide a kind of car light nearly distance light adjusting device, it is simple in structure, and it is higher that nearly distance light switches precision, the dependability height.
The technical solution of the utility model is: the nearly distance light adjusting device of a kind of car light, it comprises mount pad, mount pad is provided with a light hole, this light hole is provided with the anti-dazzling screen that is used for the car light light beam is done the dipped beam luminous intensity distribution, described anti-dazzling screen is connected with a pull bar, described pull bar can drive anti-dazzling screen and depart from light hole, connects one on the pull bar and can produce the solenoid that magnetic force spurs pull bar, also is provided with the return power apparatus opposite with the solenoid magnetic force pulling pull bar direction of motion on pull bar.
The further technical scheme of the utility model is: the nearly distance light adjusting device of a kind of car light, it comprises mount pad, mount pad is provided with a light hole, this light hole is provided with the anti-dazzling screen that is used for the car light light beam is done the dipped beam luminous intensity distribution, described anti-dazzling screen is connected with a pull bar, described pull bar can drive anti-dazzling screen and depart from light hole, connects one on the pull bar and can produce the solenoid that magnetic force spurs pull bar, also is provided with the return power apparatus opposite with the solenoid magnetic force pulling pull bar direction of motion on pull bar.Described anti-dazzling screen links to each other with mount pad by gag lever post.Described pull bar can drive anti-dazzling screen and move along the mount pad surface.
The technical scheme that the utility model is detailed is: the nearly distance light adjusting device of a kind of car light, it comprises mount pad, mount pad is provided with a light hole, this light hole is provided with the anti-dazzling screen that is used for the car light light beam is done the dipped beam luminous intensity distribution, described anti-dazzling screen is connected with a pull bar, described pull bar can drive anti-dazzling screen and depart from light hole, connects one on the pull bar and can produce the solenoid that magnetic force spurs pull bar, also is provided with on pull bar and the opposite return spring of the solenoid magnetic force pulling pull bar direction of motion.Described anti-dazzling screen links to each other with mount pad by gag lever post.Described pull bar can drive anti-dazzling screen and move along the mount pad surface.
The utility model has the advantages that:
1. the nearly distance light adjusting device of car light of the present utility model, operation precision is higher when the switching of nearly distance light, can not produce other light shape except that nearly distance light light shape, the shake of light shape when switching, light shape does not take place simultaneously, breaking down as device to guarantee to automatically revert to dipped beam light shape, guarantees the reliability of light in night running of vehicle.
2. the nearly distance light adjusting device of car light of the present utility model, simple in structure, production cost is low, be fit to promote.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is structural representation of the present utility model (during the dipped beam luminous intensity distribution).
Fig. 2 is structural representation of the present utility model (during the distance light luminous intensity distribution).
Wherein: 1 anti-dazzling screen; 2 gag lever posts; 3 pull bars; 4 return springs; 5 solenoids; 6 mount pads.
The specific embodiment
Embodiment one: as shown in Figure 1, the nearly distance light adjusting device of a kind of car light, it comprises mount pad 6, and mount pad 6 is provided with a light hole, and this light hole is provided with the anti-dazzling screen 1 that is used for the car light light beam is done the dipped beam luminous intensity distribution.
The utility model is by the far and near light of anti-dazzling screen 1 control, and anti-dazzling screen 1 is stuck on the pull bar 3, is connected with mount pad 6 by gag lever post 2.Pull bar 3 can drive anti-dazzling screen and move to depart from light hole along the mount pad surface.Connect one on the pull bar 3 and can produce the solenoid 5 that magnetic force spurs pull bar 3; On pull bar, also be provided with and the opposite return spring 4 of solenoid 5 magnetic force pulling pull bar 3 directions of motion.
During work, anti-dazzling screen 1 is in closed state with mount pad 6, covers on light hole, and the light beam that speculum penetrates is made the light distribution requirements (as shown in Figure 1) of dipped beam luminous intensity distribution to meet dipped beam.When the needs distance light, the driver presses change-over switch, and solenoid 5 energisings produce magnetic force pulling pull bar 3, and pull bar 3 drives anti-dazzling screen 1 and moves, and make distance light luminous intensity distribution (as shown in Figure 2) to the light beam of speculum this moment.After using distance light to finish, the driver presses change-over switch, solenoid 5 outages, and the elastic force of return spring 4 impels anti-dazzling screen 1 to reset, and anti-dazzling screen 1 is made the dipped beam luminous intensity distribution to meet the dipped beam requirement to the folded light beam of speculum again.
Certainly, the nearly distance light adjusting device of car light of the present utility model also can have multiple conversion and remodeling, is not limited to the concrete structure of above-mentioned embodiment.In a word, protection domain of the present utility model should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
