Abstract

The utility model relates to a headlight high/low beam switching device, the headlight is a projecting lamp. The utility model is characterized in that a fixed high beam anti-dazzling screen is arranged between a headlight lens and a curved surface reflective cup; a movable light screening sheet is arranged on the high beam anti-dazzling screen through a rotating shaft; and an electromagnetic driver unit is arranged on the high beam anti-dazzling screen. The movable light screening sheet under the action of the electromagnetic driver unit and the high beam anti-dazzling screen adjust beams reflected by a reflector so as to meet the high beam or low beam light-shape requirement; and the headlight high/low beam switching device has a simple structure, convenient operation and high reliability.

Description

The far and near light shifter of car light

Technical field

The present invention relates to the far and near switching device shifter of a kind of car light, is the device that switches lamp far away, low beam light source in especially a kind of automobile-used projection-type head lamp.

Background technology

At present, front lamp of vehicle is an irradiation function of taking into account distance light and dipped beam, and its light distributing system design is very complicated.The headlamp of more existing vehicles is a projection lamp, include curved surface transmitting mirror, light source and lens, in order to form two kinds of different irradiates light shapes of distance light and dipped beam, need to adopt far and near light shifter to finish the conversion of long-and-short distant light, but the structure of existing far and near light shifter is comparatively complicated, and reliability is low.

Summary of the invention

The purpose of this utility model is to provide a kind of handled easily, the far and near light shifter of the car light of good reliability.

The far and near light shifter of the car light of the utility model design is characterized in that: between the lenticular body of car light and curved surface reflector a fixing distance light anti-dazzling screen is arranged; One active catch mating plate is installed on the distance light anti-dazzling screen by rotating shaft, and an electromagnetic driver is installed on the distance light anti-dazzling screen; One linkage part, the magnetic core push rod of connection active catch mating plate and electromagnetic driver is equipped with back-moving spring on the magnetic core push rod.

Advantage of the present utility model is: when needs use high beam, the driver presses the power conversion switch, the coil electricity of electromagnetic driver, make the magnetic core push rod because of the magnetic energy that produced by coil influences, make it to be adsorbed and retreat, simultaneously also relatedly make linkage part stir the active catch mating plate to do packing up of rugosity along rotating shaft, at this moment, the no longer shading of active catch mating plate, the light beam of speculum blocks luminous intensity distribution by the distance light anti-dazzling screen, realizes by the switching of dipped beam to distance light.When not needing to use high beam, the driver resets the power conversion switch, the coil blackout of electromagnetic driver, the magnetic core push rod moves outside under the effect of back-moving spring, simultaneously also relatedly make linkage part stir the active catch mating plate to do to reset activity along rotating shaft, the active catch mating plate blocks to meet the light shape requirement of dipped beam with the light beam of distance light anti-dazzling screen to mirror reflects, and is simple in structure, easy to operate, the reliability height.

The specific embodiment

Cause Fig. 4 with reference to figure 1, be the far and near light shifter of a kind of car light, described car light is a projection lamp, and the light source 1 of car light has a fixing distance light anti-dazzling screen 4 between the lenticular body 3 of car light and oval curved surface reflector 2 in oval curved surface reflector 2; One active catch mating plate 5 is installed on the distance light anti-dazzling screen 4 by rotating shaft 51, and there is a breach 41 (Fig. 2) the corresponding position that the active catch mating plate is installed of fixing distance light anti-dazzling screen, and this breach is just blocked by the active catch mating plate during installation; Electromagnetic driver 6 is that this electromagnetic driver 6 is installed on the distance light anti-dazzling screen 4 at coil 61 internal magnetic core push rods 62; One linkage part 7, the magnetic core push rod 62 of connection active catch mating plate 5 and electromagnetic driver is equipped with back-moving spring 8 on the magnetic core push rod 62.

With reference to figure 1, Fig. 2, Fig. 5 and Fig. 6, when needs use high beam, the driver presses the power conversion switch, and the coil electricity 61 of electromagnetic driver 6 makes magnetic core push rod 62 influence because of the magnetic energy that produced by coil, make it to be adsorbed and retreat, simultaneously also relatedly make linkage part 7 stir active catch mating plate 5 to make pack up (Fig. 2, Fig. 5) of rugosity along rotating shaft 51, at this moment, no longer shading of active catch mating plate 5, the light beam of speculum 2 blocks luminous intensity distribution by the distance light anti-dazzling screen, realizes by the switching of dipped beam to distance light.When not needing to use high beam, the driver resets the power conversion switch, the coil blackout of electromagnetic driver 6, magnetic core push rod 62 moves outside under the effect of back-moving spring 8, simultaneously also relatedly make linkage part 7 stir active catch mating plate 5 to do to reset activity along rotating shaft, active catch mating plate 5 requires (Fig. 1 and Fig. 6) with distance light anti-dazzling screen 4 to the light shape that the light beam of mirror reflects blocks to meet dipped beam.

Claims
