Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low-beam and high-beam automotive headlamp apparatus having a casing, in which a light source and a reflecting mirror are arranged, and the light source is provided. , With the adjustment member being switchable between a position for the low beam and a position for the high beam relative to the reflector.

[0002]

2. Description of the Related Art A headlight device of this type is known, for example, from DE-A 44 35 507. In the headlight device disclosed in this known specification, the light source is arranged so as to switch between the position for the low beam and the position for the high beam in the direction of the optical axis of the reflector and with respect to the optical axis of the reflector. So that it can be moved vertically. Perpendicular to the optical axis means that the pivot plane has a vertical extension and the optical axis extends into this pivot plane. To switch, the light source
The adjustment member causes the light source to pivot relative to the reflector about the light source rotation axis. The light source rotation axis extends horizontally with respect to the optical axis of the reflector and at a distance from the optical axis. Horizontal with respect to the optical axis means that the light source pivot axis is horizontal and extends perpendicular to the optical axis. The adjusting member can be configured as an electric motor, as a hydraulic or pneumatic drive, or as an electromagnet.

[0003] The electromagnet needs to be relatively large and strong in order to reliably fulfill the function as an adjusting member. The stroke of the electromagnet must be large enough to be able to travel the required path to switch the headlight device between the position for the high beam and the position for the low beam. Although this path can be shortened by a suitable gearbox, the electromagnets have the disadvantageous side effect of overcoming significantly greater adjusting forces and having to be configured accordingly. The larger and stronger the electromagnets are, the heavier they are, and therefore require more installation space. However, small and lightweight electromagnets cannot reliably fulfill the function of the adjusting member for switching between the position for the low beam and the position for the high beam.

[0004] German Patent Publication No. 443,550.
According to the headlight device known from U.S. Pat. No. 7,074,749, the headlight range is not changed by means of a motor for adjusting the headlight range and the like. However, especially when incorporating recent headlamps with a strong luminous flux, the headlight range is changed around the vehicle horizontal axis, independent of the inclination of the vehicle, so that when the headlight is turned on, It is important that road users other than vehicles are not dazzled.

[0005]

Based on the above-mentioned drawbacks, the object of the present invention is to improve a headlight device of the type mentioned at the outset by providing a position for the low beam and a position for the high beam. The switching between the two can be performed by means of an adjusting element having a structure which is as small and light as possible, which ensures a reliable and reliable switching function.

[0006]

According to the present invention which solves this problem, according to the headlight device of the type described at the outset,
The reflecting mirror is movable by a motor for adjusting a headlight range (Leuchtweite; beam reach distance) relative to the casing, and the adjusting member includes a motor for adjusting the headlight range and two electromagnets. have.

[0007]

According to the headlight device of the present invention, the headlight is already provided in the headlight device for switching the headlight between the position for the low beam and the position for the high beam. A motor for adjusting the headlight range is used. With this motor, on the one hand, the headlight range of the reflector is centered on the reflector pivot axis, which is generally horizontal to the reflector's optical axis and extends at a distance from this optical axis. Can be adjusted perpendicular to the optical axis. The motor for adjusting the headlight range is pivotally mounted on the reflector at a predetermined distance from the reflector pivot axis. The motor performs a linear sliding motion, whereby the reflector is pivoted about the reflector pivot axis. By appropriate control of the motor, the headlight range of the headlight device is changed around the vehicle's lateral axis in relation to the inclination of the vehicle, whereby the vehicle is switched on when the headlight is turned on. Other road users will not be dazzled. This is particularly advantageous when using modern headlamps with a strong luminous flux.

[0008] The motor for adjusting the headlight range, on the other hand, performs the original work of switching the headlights. The two electromagnets simply perform a holding function. The first electromagnet is used to hold the light source in a corresponding position relative to the reflector when the headlight is switched to a position for the high beam. The second electromagnet is held in place relative to the casing while the light source is being switched by the motor, so that the motor for headlight range adjustment is relatively relative to the casing. When the reflector is turned, the headlight is switched from a position for the low beam to a position for the high beam.

Due to the fact that the two electromagnets fulfill only the holding function and do not need to have a switching function, these two electromagnets can be constructed in a particularly lightweight and small construction. Since the original switching function is performed by the motor for adjusting the headlight range, a reliable and reliable switching function is assured despite the small size and weight of the electromagnet. According to the headlight of the present invention, it is not necessary to use an expensive dual-function motor having a relatively large structure and a complicated structure to switch the headlight between the low beam and the high beam.

Thus, the motor for adjusting the headlight range satisfies two functions. On the one hand, this motor changes the headlight range of the headlight device, and on the other hand, this motor
In cooperation with the two electromagnets, it acts as an adjusting member for switching the headlight between a position for the low beam and a position for the high beam.

[0011]

According to an advantageous embodiment of the invention, the headlight device has a control unit, which comprises a motor for adjusting the headlight range,
An electromagnet for switching between a position for the low beam and a position for the high beam is controlled. The motor for headlight range prominence makes it possible to change the headlight range of the headlight device in a general manner. Only when switching the lighting function, i.e. when switching the low beam to the high beam or vice versa, the control unit switches the motor from the headlight range adjustment function between the position for the low beam and the position for the high beam. Bring to function. When the switching process has ended, ie when the lighting function has been switched, the control unit brings the motor again from the switching function to the original headlight range adjustment function.

[0012] Advantageously, the light source is movable relative to the reflector between a position for the low beam and a position for the high beam to effect the switching. Also advantageously,
The light source is slidable substantially parallel to the optical axis of the reflector. Thereby, the concentration of the light beam reflected by the reflecting mirror is obtained. Alternatively or additionally, the light source is pivotable perpendicular to the optical axis of the reflector. Thereby, the light beam reflected by the reflecting mirror can be raised.

According to an advantageous embodiment of the invention, the light source is pivotable with respect to the reflector at a light source pivot axis extending horizontally with respect to the optical axis of the reflector and spaced apart from the optical axis. It is supported. By pivoting about a light source pivot axis arranged in this manner, the light source is displaced substantially parallel to the optical axis of the reflector and pivoted perpendicular to the optical axis. As a result, the light beam reflected by the reflector is concentrated and raised. It is also conceivable to form a light source turning axis on the optical axis of the reflecting mirror.
By doing so, of course, even if the light source is turned around the light source turning axis, it will not be shifted backward in the light emission direction parallel to the optical axis.

According to another advantageous embodiment of the invention, a light source is provided in which the first electromagnet is moved to a position for a low beam or a position for a high beam relative to a reflector in an operating state. Has been proposed to hold in a position relative to the reflector.

According to an advantageous embodiment of the invention, the headlight device has a spring member between the reflector and the light source,
The spring member presses the light source to a predetermined turning position with respect to the reflecting mirror, and at this time, the electromagnet is pulled against the spring force. The pivot position advantageously corresponds to a position for the low beam. The spring element is preferably designed as a pressure spring.

According to an advantageous embodiment of the invention, the first electromagnet is fixed to the reflector at a distance from the optical axis of the reflector. Also advantageously, a first magnetizable flange is arranged opposite the working side of the first electromagnet and spaced apart in a non-operating state of the first electromagnet by a spring member, A flange is fixed to the light source. The first flange is at least partially made of a magnetizable material. The flange is coated with a magnetizable material or the magnetizable material is embedded in the flange.

The reflector is pivotally supported on the casing by a reflector pivot axis extending along a reflector pivot axis extending horizontally with respect to the optical axis of the reflector and spaced apart from the optical axis. May be. However, also according to an advantageous embodiment of the invention, the reflector is pivoted on the casing with a reflector pivot axis extending horizontally with respect to the optical axis of the reflector and spaced apart from the optical axis. Supported as possible.

According to an advantageous embodiment of the invention, the second electromagnet is arranged in the headlight device in such a way that it holds the light source in an operating state relative to the casing. .

According to an advantageous embodiment of the invention, the second electromagnet is fixed to the housing. Also advantageously, facing the working side of the second electromagnet is arranged a second magnetizable flange which is spaced apart in a non-operating state of the second electromagnet, said flange being provided with a flange. Fixed to the light source. The second flange is also at least partially
Made of magnetizable material.

According to another advantageous embodiment of the headlight device according to the invention, the second electromagnet connects the light source to the reflector when the second electromagnet is in operation, so that the reflector pivot axis can be adjusted. It is arranged in the headlight device such that the pivoting movement of the reflector with respect to the centered casing is diverted to a pivoting movement about the light source pivot axis relative to the reflector. The turning movement of the reflecting mirror about the turning axis of the reflecting mirror is performed by a motor for adjusting a headlight range. The second electromagnet is preferably fixed to the light source.

According to an advantageous embodiment of the invention, a second magnetizable flange, which is arranged opposite the working side of the second electromagnet and is inactive with the second electromagnet, spaced apart therefrom. And the flange is connected to the reflector at a distance from the reflector pivot axis via a Bowden cable, the Bowden cable being centered about the reflector pivot axis relative to the casing. The turning movement is changed to a turning movement of the second flange relative to the reflecting mirror.

The sliding movement of the second flange relative to the reflector when the second electromagnet is actuated causes a pivoting movement about the light source pivot axis relative to the reflector.

It is also advantageous that the working side of the second electromagnet and the second flange extend parallel to or parallel to the pivot plane of the light source.

The headlight device according to the invention is also particularly advantageous if the light source is configured as a gas discharge lamp, in particular a Xenon lamp.

Hereinafter, a method for switching the headlight device from the low beam to the high beam according to the present invention will be described in detail. If the headlight device is not switched, the motor for headlight range adjustment is in a mode for headlight range adjustment. In order to switch the headlight device, the motor is switched from a mode for headlight range adjustment to a switching mode. In the position for the low beam, the two electromagnets are inactive. The light source and the reflector are in a predetermined initial position relative to each other and with respect to the casing.

To switch the headlight, a second electromagnet is first activated. This keeps the light source in its initial position relative to the casing. In the next step, the reflector is pivoted vertically upward by a motor for headlight range adjustment about the reflector pivot axis. Since the light source is held in its initial position relative to the casing, by pivoting the reflecting mirror relative to the casing, the light source causes the reflecting mirror to resist the spring force of the pressing spring. It is made to make a relative swiveling motion. When the light source is pivoted until the first magnetizable flange abuts the working side of the first electromagnet, the first electromagnet holds the light source in this pivoted position relative to the reflector. Actuated to do so.

The light source has now reached the position for the high beam. Then, it is only necessary to pivot the reflector with the light source to its initial position. For this purpose, the second electromagnet is actuated, and the reflector is pivoted vertically downward about the reflector pivot axis by the motor for headlight range adjustment. The entire headlight is then located at its high beam position.

The method for switching a headlight device from a high beam to a low beam is significantly simpler. To do so, it is only necessary to operate the first electromagnet. Due to the spring force of the pressure spring, the light source is pivoted vertically upward relative to the reflector and again assumes its initial position.

The headlight device according to the invention is such that when one or two electromagnets fail, the headlight occupies a position for the low beam anyway and other road users are dazzled. Not configured. If the second electromagnet fails, the headlight cannot be switched from the position for the low beam to the position for the high beam. If the first electromagnet fails, the headlamp automatically switches from the position for the high beam to the position for the low beam by the spring force of the pressing spring.

Then, a motor 9 for adjusting the headlight range is controlled by the control unit 10 and this motor 9 turns the reflecting mirror 4 in the direction of the arrow 18 by the angle α (see FIG. 2) about the turning axis 8 of the reflecting mirror. It is turned. The light source 3 is a second electromagnet 16
Is actuated so that it is held in its pivoted position relative to the casing 2 so that the light source 3
It does not follow the turning motion of. During the pivoting movement of the reflector 4 relative to the casing 2, the light source 3 resists the spring force of the pressing spring 12 until the first flange 13 hits the working surface 11 a of the first electromagnet 11. And is turned relatively to the reflecting mirror 4. First electromagnet 1
1 is actuated, whereby the first flange 13 is held on the actuation surface 11a of the first electromagnet 11. This holds the light source 3 in its instantaneous pivot position relative to the reflector 4. Next, the second electromagnet 16 is deactivated again. The control unit 10 controls the motor 9 for adjusting the headlight range in the following manner. In other words, control is performed so that the reflecting mirror 4 and the light source 3 can be turned back around the reflecting mirror turning axis 8 in the direction of the arrow 19 and turned. Thus, the headlight device 1 is located at the position for the high beam (see FIG. 3). The reflecting mirror 4
At its initial position (see FIG. 1), the light source 3 is shifted backward (light emission direction 7) along the optical axis 5 of the reflector 4,
It is pivoted vertically downward (in a direction away from the optical axis 5 of the reflector 4).

To switch the headlight device 1 according to the invention back from the position for the high beam to the position for the low beam again, it is only necessary to operate the first electromagnet 11. The light source 3 is again turned to its initial position (see FIG. 1) about the light source turning axis 6 by the spring force of the pressing spring 12.

FIGS. 4 and 5 show a second embodiment of the headlight device according to the present invention. The headlight device shown is
The position for the low beam (FIG. 4) is switched without switching to the position for the high beam (FIG. 5).

The headlight device 1 shown in FIGS. 4 and 5 has substantially the same configuration as the headlight device 1 shown in FIGS. The difference from the headlight device 1 shown in FIGS. 1 to 3 is that the second electromagnet 16 is fixed to the web structure 14 of the light source 3. A second magnetizable flange 17 is arranged facing the working surface 16a of the second electromagnet 16 and spaced apart therefrom. Second
Is connected to the reflector 4 via a Bowden cable 20 at a distance from the reflector pivot axis 8. The Bowden cable 20 converts the turning movement of the reflecting mirror 4 about the turning axis 8 with respect to the casing 2 into the sliding movement of the second flange 17 with respect to the reflecting mirror 4.

, And a second electromagnet 16.

In order to switch the headlight device 1 according to the invention from a position for the low beam (FIG. 4) to a position for the high beam (FIG. 5), first the second electromagnet 16 is activated and the second electromagnet 16 is activated. The flange 17 is held on the working side 16 a of the second electromagnet 16. The motor 9 for adjusting the headlight range is then controlled by the control unit 10 so that the reflecting mirror 4 is turned in the direction of arrow 18 about the reflecting mirror axis 8 by an angle α (see FIG. 2). . When the second electromagnet 16 is actuated, the second flange 17 is held on the actuation surface 16a of the second electromagnet.
The turning position of the reflecting mirror 4 around the center shifts to a turning motion of the light source 3 about the light source turning axis 6 relative to the reflecting mirror 4 via the Bowden cable 20. The turning movement of the light source 3 is performed against the spring force of the pressing spring 12.
At the end of the swiveling movement of the light source 3, the first flange 13

The reflecting mirror 4 is turned upward by an angle α from its initial position (see FIG. 4), and the light source 3 is moved backward along the optical axis 5 of the reflecting mirror 4 (in a direction opposite to the light emitting direction 7). It is displaced and turned upward (away from the optical axis 5 of the reflecting mirror 4) in the vertical direction.

For normal headlight drive outside the switching drive, the second electric motor 16 is deactivated again. Thus, the motor 9 for adjusting the headlight range can adjust the headlight range of the headlight device 1 in a known manner.

The first electromagnet 11 is deactivated in order to switch the headlight device 1 according to the invention from the position for the high beam back to the position for the low beam. Light source 3
