Description

[Detailed Description of the Invention] The present invention relates to a vehicle headlamp. Specifically, by dividing the reflector into a rear half and a front half without deteriorating its reflective performance, it is possible to simplify the manufacture of the reflector, and also to increase the selectivity of the design suitable for vehicle headlamps. The present invention aims to provide a new vehicular headlamp that can be expanded.

When it comes to vehicle headlights, especially automobile headlights, the relationship with the vehicle body design cannot be ignored. That is, it is necessary that the external shape is adapted to the vehicle body line, and it is necessary that no part of the headlight protrudes from the vehicle body line. If the vehicle body, especially the front sides, has steep curves, the lens surface cannot be made flat (that is, perpendicular to the optical axis) and must be tilted. Then, the aperture edge of the reflecting mirror corresponding to the lens must also be cut diagonally. However, there is the problem that reflective mirrors must have an effective reflective surface of a certain value or more, so if the opening edge is cut diagonally, the depth must be increased to compensate for the lost reflective surface. I have to do it. If such a deep reflective mirror is formed from a metal plate, the metal plate will need to be deep drawn, resulting in poor workability and low yield, as well as strong spring back. You will not be able to obtain

Therefore, the present invention aims to provide a new vehicle headlamp that can easily obtain a deep reflecting mirror, and includes a reflecting mirror with an opening at the front and a covering for the front opening of the reflecting mirror. It comprises a lens, and a light source placed in a space limited by the reflecting mirror and the lens, and the reflecting mirror has a rear half and a front half formed as separate members. The second half is formed by drawing a metal plate, and the first half is made of synthetic resin.
It is characterized in that the rear opening edge of the front half is integrally attached to the opening edge of the rear half.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Details of the vehicle headlamp of the present invention will be described below with reference to embodiments shown in the accompanying drawings.

In the figure, reference numeral 1 denotes a reflecting mirror, which consists of a rear half 2 and a front half 3. A mounting hole 4 is formed approximately at the rear center of the rear half portion 2, and a light bulb 5 for a light source is removably mounted in the mounting hole 4 by a known method. Further, an installation flange 6 projecting outward is formed on the front opening edge of the rear half portion 2.
An upright edge 7 is formed on the outer edge of the flange 6 and projects forward. The latter half 2 is formed by pressing a metal plate, and a reflective surface is formed on the inner surface 8 by vacuum deposition of aluminum or the like.

The front half 3 of the reflecting mirror 1 is molded from synthetic resin. The inner surface 9 is formed to be continuous with the inner surface 8 of the second half portion 2, and a reflective surface is formed on the inner surface 9 by vacuum deposition of aluminum or the like. A rib 10 is protruded from the outside of the rear opening edge of the front half portion 3, and a groove 11 is formed thereby.

A lamp body 12 of a side marker lamp is integrally connected to one side edge of the front opening of the front half portion 3 of the reflecting mirror 1. A light bulb 13 is attached to the rear center of the vehicle side light lamp body 12. Reference numeral 14 denotes a shade projecting forward from the opening edge on the headlight side of the side lamp body 12.

A lens installation groove 15 that opens toward the front is formed at the front peripheral edge of the integrated body of the first half of the reflector 3 and the sidemarker lamp body 12.

The rear opening edge of the first half part 3 of the reflector is placed on the front surface of an installation flange 6 formed at the front opening edge of the second half part 2, and is bonded with an adhesive. Note that the connection between the two reflecting mirror parts is not by adhesive, but by an appropriate engagement means, such as forming a protrusion from the front half and engaging the protrusion with an engagement notch formed on the rear half. Alternatively, an adhesive means may be used in combination with this, and in any case, it is sufficient that both members are integrally formed.

Reference numeral 16 denotes a lens made of synthetic resin, and is formed in a shape and size that can cover the front surface of the headlight reflector 1 and the front surface of the sidemarker lamp body 12. A projecting edge 17 is formed on the peripheral edge of the lens 16 and projects rearward. And this lens 16
A peripheral edge 17 is adhesively fixed in a lens installation groove 15 formed on the peripheral edge of the reflector front half portion 3--sidemarker lamp body 12 integrated body. At this time, the front end of the shade 14 comes into contact with the inner surface of the lens 16.

The headlamp structure 18, in which the headlamp and the sidemarker lights are integrally formed as described above, is tiltably supported by a housing 19 fixed to the vehicle body, and its support will be explained. The headlamp structure 18 is attached to the housing 19 by means of one tilting fulcrum 20 and two adjuster steering parts 21 (only one of which is shown). The positional relationship of these connection points is such that, when viewed from the front, the tilting fulcrum part 20 is located at the upper right (or upper left), and one of the adjuster steering parts 21 is located at the upper left (or upper right). , the other azimuth steering section is arranged at the lower right side (or at the lower left side). That is, when viewed from the front, one of the adjusting parts 21 is centered around the tilting fulcrum part 20.
The fulcrum section 20 is located at a position horizontally spaced apart from the fulcrum part 20, and another adjusting section is located at a position vertically spaced from the fulcrum part 20.

The tilting fulcrum portion 20 consists of a receiver 22 and a sphere 23. The sphere 23 projects laterally from a bracket 24 fixed to the rear portion 2 of the reflector 1. The receiver 22 is made of synthetic resin and has a block shape, and is attached to a bracket 25 fixed to the housing 19.
is fixed. A spherical recess 26 is formed in the receiver 22, and the spherical body 23 is fitted into the spherical recess 26, thereby forming the tilting fulcrum 20.

The adjusting section 21 has an adjusting screw 27 as a main component. 28
is a self-locking nut fixed to the housing 19, and the adjusting screw 2 is attached to this.
The tips of No. 7 are screwed together. A collar 30 is integrally formed slightly rearwardly from the head 29 of the adjusting screw 27, and the adjusting screw 27 is fixed to the rear half portion 2 of the reflector between the collar 30 and the head 29. The bracket 31 is engaged. As a result, the adjusting section 21 is configured, and the adjusting screw 27 is attached to the self-locking nut 28.
When the bracket 31 is screwed in, the portion of the bracket 31 that engages with the adjusting screw 27 moves rearward, and conversely, when the adjusting screw 27 is unscrewed from the self-locking nut 28, the portion of the bracket 31 that engages with the adjusting screw 27 moves rearward. The part will move forward. The other adjuster staying portion (not shown) also has this adjuster staying portion 21.
It is configured in the same way.

Therefore, when the adjusting screw 27 is operated (screwing in or out of the self-locking nut 28), the headlight structure 18 connects the tilting fulcrum part 20 and the other adjusting part. When the headlamp structure is tilted about the line as an axis and the adjuster steering screw in the other adjuster steering section is operated, the headlamp structure is tilted about the line connecting the tilting fulcrum part 20 and one adjuster stayer 21. Become.

In addition, if the threads of the adjusting screw are multi-thread screws such as double-thread screws or triple-thread screws, the tilting work can be done quickly, and the engagement with the self-locking nut is loose. There is no such thing as becoming.

As described above, in the vehicle headlight of the present invention, the reflector is composed of two parts, the latter half and the first half, so even if the reflector is deep, it can be easily adjusted. , can be manufactured at low cost and with high precision, and because the rear and front parts of the reflector are integrally attached,
Both reflective surfaces can be formed continuously, and dark areas can be eliminated when the headlight is viewed from the front.

Furthermore, by configuring the reflector in two parts, one of the parts can be made of synthetic resin, and the lamp body of the side lamp can be integrally formed with this, expanding the range of applications. can.

In the above embodiment, the shade 14 not only serves to block light between the headlights and the side marker lights, but also serves as reinforcement, and also serves to support the large lens when it is pressed from the front. I am accomplishing it.
