Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel vehicle headlight. More specifically, the present invention is intended to provide a new vehicle headlamp in which the product name and the like can be displayed on the front surface without using a cover that must be removed at the time of use.

[0002]

2. Description of the Related Art In a conventional vehicle headlight, for example, a fog lamp or a spot lamp, when a product name or the like is to be displayed on the front surface of the headlight, an opaque material covering the entire lens surface of the headlight is used. A lamp cover is provided, and a product name or the like is displayed on the surface of the lamp cover.

[0003]

In the above-mentioned conventional vehicle headlamp, when the headlamp is turned on, the lamp cover must be removed by human hands or by providing a drive source and by remote control. However, if it is done manually, you have to go out and remove the cover, which is bothersome and
In the case of remote control, there are drawbacks that the device itself is large and expensive.

[0004]

In order to solve the above-mentioned problems, the vehicle headlamp of the present invention is formed by covering the front opening of a reflector having a front surface with a front lens and defining the reflector and the front lens. A light source bulb is arranged in a space, a lens guard is arranged on the front side of a front lens, and a plate made of a light-transmitting plate material is attached to the lens guard.

[0005]

Therefore, in the vehicle headlamp according to the present invention, since the plate is formed of the translucent plate material, it is not necessary to remove the plate at the time of lighting, and the troublesomeness of the prior art is eliminated. Moreover, it is possible to prevent the apparatus from becoming large and expensive.

6 is attached to the front end of the lamp body 2.

In addition, 31, 31, ... Are guard portions 28,
28, ... Appropriate ones, in the present embodiment the one located at the lowermost end 28 and the one located immediately above it 28.
Engagement protrusions protruding from the rear edge of the rear portion, which are formed at a substantially central portion in the left-right direction and are appropriately separated from each other in the left-right direction.

A mark plate 32 is made of transparent synthetic resin such as polycarbonate. The mark plate 32 has a horizontally long rectangular plate portion 33 when viewed from the front, and a locking portion projecting rearward so as to extend parallel to each other from vertically spaced apart positions in the center of the rear surface of the plate portion 33. The leg pieces 34, 34 are integrally formed. Engaging claws 34a, 34a are provided at the tip ends of the surfaces of the locking leg pieces 34, 34 located on the opposite sides.

The distance between the surfaces of the locking leg pieces 34, 34 located on opposite sides is set slightly larger than the distance between the rear edges of the guards 28, 28, ... Of the lens guard 26. Has been done. In addition, the engaging claws 34a, 34a
The gap between the rear surface of the plate portion 33 and the rear surface of the plate portion 33 is formed to be approximately the same as the front-back width of the guard portions 28, 28, ... Of the lens guard 26.

On the rear surface of the plate portion 33 of the mark plate 32, a sticker (not shown) displaying a mark such as a product name is attached. Therefore, when viewed from the front, the mark displayed on the sticker can be visually recognized. It It is to be noted that what is displayed on the sticker may be not only the mark but also the character, or only the character may be displayed instead of the mark.
What you want to display may be displayed appropriately.

Then, in the mark plate 32, locking leg pieces 34, 34 are inserted between two adjacent guard portions 28, 28 of the lens guard 26. Guard parts 28, 2
Since 8 ... has a V-shaped cross-section,
Since the engaging claws 34a, 34a of the locking leg pieces 34, 34 move along the inclined surfaces 28a, 28a of the guard portions 28, 28, the leading ends of the locking leg pieces 34, 34 are moved backward. The engaging claws 34 are bent so as to approach each other.
When a and 34a pass the rear ends of the guard portions 28 and 28, the bent locking leg pieces 34 and 34 are returned to their original positions, and the engaging claws 34a and 34a are engaged with the rear edges of the guard portions 28 and 28. The mark plate 32 is thereby supported between the adjacent guard portions 28, 28.

The interval between the engaging protrusions 31, 31, ... Formed on the rear edges of the guard portions 28, 28 is approximately equal to the width of the tip portions of the locking leg pieces 34, 34 of the mark plate 32. ,
The engagement claws 34a, 34a of the locking leg pieces 34, 34 are engaged with the guard portions 28, 28 at the rear edges thereof by the engagement projections 31, 31,
.., the mark plate 32 is positioned, and the position does not move due to vibration or the like during traveling.

In the spot lamp 1 described above,
Two lens guards 28, 2 with adjacent product names, etc.
Since the mark plate 32 attached between the eight parts is used, the required light distribution can be obtained without removing the mark plate during use, and thus there is no need to remove the cover as in the conventional case.

When it is necessary not to give a dazzling light to the driver of an oncoming vehicle, to reduce the light intensity, or to diffuse the light, it is necessary to have a mark plate of a necessary size. Should be attached to the required place.
In this way, when the purpose is to control the light distribution to some extent, the portions other than the display such as marks are left transparent, and appropriate lens elements such as fisheye lens elements and prism elements may be formed on the back surface or front surface thereof.

Regarding the formation of the display of the marks and the like, in the above description, an example in which a sheet having the display of the marks and the like is attached to the back surface of the plate portion 33 is shown, but the present invention is not limited to this, and printing, hot stamping, etc. It may be formed by an appropriate means. Further, the display location is not limited to the back surface of the plate portion 33, and may be formed on the front surface. However, the plate part 33
By forming it on the back surface of the display, peeling of the display is prevented, and the display has a sense of depth. Incidentally, these displays are not limited to the light non-transmissive ones, and may be semi-transmissive ones. In such a case, by properly selecting the transmissivity, the above-mentioned light distribution control is also useful. .

[0032]

As is apparent from the above description, in the vehicle headlamp of the present invention, the front opening of the reflector having the front opening is covered with the front lens, and the space defined by the reflector and the front lens is provided. A light source bulb is arranged inside, a lens guard is arranged on the front side of the front lens, and a plate made of a light-transmitting plate material is attached to the lens guard.

Therefore, in the vehicle headlight of the present invention,
Since the plate is formed of a translucent plate material, it is not necessary to remove the plate at the time of lighting, there is no troublesomeness as in the conventional case, and it is possible to prevent the apparatus from becoming large and expensive.

It should be noted that the specific shapes and structures of the respective parts shown in the above-mentioned embodiments are merely examples of the embodiment when the present invention is carried out, and the technical form of the present invention can be realized by these. The range is not to be construed as limiting.
