Abstract

The utility model provides a full-low beam regulator device for auto lamp. The utility model contains a shell. One end of the shell along axis direction forms a connection interface and the other end is connected with a rear cover; the rear cover is embedded with a permanent magnet; a coil group is provided inside the shell and the coil group is a reel provided with a via in the axis direction and wound with two groups of winding along the outer edge; the upper part of the reel is connected with an inner core which can move along the axis direction and the other end of the inner core is connected with a bulb which is provided with a reflecting cover. When the coil group is charging, the coil group will attract mutually with the permanent magnet and drive the bulb to move backward and downward and the bulb forms a high lamp (full-beam lamp) after a reflection through the auto lamp cover; when the coil group is cut off power, the bulb will move upward and toward to make the bulb return to the original height and form a low lamp (low-beam lamp).

Description

The far and near lamp adjusting device of car light

Technical field:

The utility model relates to a kind of device of headlight, relates in particular to a kind of far and near lamp adjusting device of car light.

Technical background:

The employed headlight of general vehicle mainly is to possess the bulb (having two luminous points) that a pair of tungsten filament is arranged, and utilizes again to switch tungsten filament changes focal length to change luminous point the type of focusing, to obtain the effect of far and near lamp.

Recently but developing the xenon lamp single spot bulb that a kind of brightness outclass osram lamp uses on automobile, yet it but can only provide the luminous point of a high brightness, though brighter lighting source is provided, but making in use, this kind xenon lamp single spot bulb can't resemble purpose and the effect that two luminous point osram lamps directly reach the far and near lamp of switching, so get effect for obtaining far and near lamp, generally get form with two reflections of each configuration lamp socket in the headstock both sides, so that high beam and dipped headlights to be provided respectively, but this way, cause cost to improve again, and got vehicle and can't be suitable for and change the outfit for single emission lamp socket is set originally.So be necessary to provide a kind of can distance switch xenon lamp light source body.

The specific embodiment:

To shown in Figure 3, the far and near lamp adjusting device of the car light of the utility model embodiment is made up of housing 1, permanent magnet 2, coil groups 3, inner core 4, an xenon lamp 5, a connecting seat 6, an adapter sleeve 7, a reflection shield 8 according to Fig. 1.

This housing 1 is the tubular body of the both ends open of a hollow, and a housing end opening vertically forms connector 20, and the other port is connected with a tail-hood 10 closed ports; Be provided with a holder 11 in tail-hood 10, this holder 11 is a slice circular piece, and there is a tubular body that is hollow the centre, is equipped with a spring 27 in the pore; On holder 11, be with the permanent magnet 2 of an annular; Housing 1 below periphery is provided with opening and forms line outlet 25, supplies the lead-in wire of bulb 5 and coil groups 3 to pass; As Fig. 3, housing 1 connector 20 outside wall surface are provided with 2 L shaped short slots 19, and connector 20 inwalls are provided with the draw runner 21 of protrusion.

This coil groups 3 is one and is provided with the line wheel that perforation and outer rim are arranged with two groups of windings vertically, during energising, and the online two groups of magnetic loops that the winding polarization is opposite of taking turns of winding; On coil groups 3 one ends, be provided with a bolt buckle 14.

In conjunction with Fig. 3, Fig. 4, Fig. 5 and Fig. 6, these inner core 4 lower ends are provided with a fork 16, match with the bolt buckle 14 of coil groups 3 one ends, by connector inner core 4 are connected on the coil groups 3; These inner core 4 outer walls are provided with chute 17, and this chute 17 tilts to have certain angle from front to back, and chute 17 tail ends are provided with stop part 26; The manufactured materials of this inner core 4 is the heatproof pottery.

One bulb 5 is that an xenon is put bulb 5, in have a single luminous point, bulb 5 one ends link to each other with inner core 4.

As shown in Figure 3, on housing 1 connector 20, be with an adapter sleeve 7, one concave point arranged at adapter sleeve 7 inwalls; Connector 20 outer walls are provided with 2 L shaped short slots 19, and when adapter sleeve 6 linked to each other with connector 20, concave point slipped into short slot 19, with angle of adapter sleeve rotation, just adapter sleeve 7 have been fixed on the connector 20 again.

As shown in Figure 7, one is used for the Connection Block 7 that combines with lamp socket, snaps onto during installation on the adapter sleeve 6, and the ring place is provided with several and connects haptic element 24 in Connection Block 7, by welding Connection Block 7 is fixed on the adapter sleeve 6.

In conjunction with Fig. 1, Fig. 2 and Fig. 3, one reflection shield 8, one end has connecting hole 13, corresponding with the connecting hole 23 on the Connection Block, by screw reflection shield is fixed on the adapter sleeve 6, reflection shield 8 belows are provided with opening 9, and a fixing hole 13 is arranged at the reflection shield bottom, by screw it is linked to each other with connecting hole 23 on the Connection Block, reflection shield is fixed on the Connection Block.

With reference to figure 1 and Fig. 3, by coil groups 3 is switched on, make coil groups 3 produce magnetic field, just make coil groups 3 overcome the elastic force effect of spring, move backward and adsorb mutually with permanent magnet 2, thereby driven inner core 4 and bulb 5 bottom offset mutually together, because the displacement of bulb 5 has changed the focusing of bulb 5 on lamp shade, just formed lamp effect far away like this, then again by coil groups 3 is cut off the power supply, make coil groups 3 lose magnetic field effect, under the effect of spring 27 elastic force, move 3 groups of phase fronts of propelling coil, thereby also drive inner core 4 and bulb 5 displacement forward, make bulb 5 get back to original position again, just formed the effect of low beam.

In conjunction with Fig. 4 and Fig. 5, chute 17 bottoms on inner core 4 outer walls are provided with stop part 26, connector 20 inwalls are provided with the draw runner 21 of the certain angle that tilts from front to back, make bulb 5 that displacement also be arranged when moving axially in the horizontal direction, make the regulating effect of distance of light desirable more: when coil groups 3 energisings, coil groups 3, inner core 4 and bulb 5 be interlock forward or backward together, and by the effect of draw runner 21 and chute 17, inner core 4 and bulb 5 are towards reflection shield direction displacement 2mm-3mm.
