Description

[Detailed description of the invention] <Industrial field of application> The present invention relates to an automobile headlamp, and more specifically to an automobile headlamp of a movable reflector type in which a reflector is installed within the lamp body so that aiming can be freely adjusted. It is something.

<Conventional technology> Although the aiming of automobile headlights is adjusted in advance by the lamp manufacturer, after it is assembled into the automobile,
That is, it is necessary to further adjust the aiming when the vehicle is shipped or after it has been assembled into the vehicle and used for a certain period of time.

Conventionally, in the case of movable reflector type headlights, the vehicle was placed on a horizontal floor, the headlights were turned on, and the aiming adjustment was performed while projecting the light distribution onto a screen installed in front of the vehicle. was doing. For this reason, special equipment and equipment were required to make aiming adjustments, and there were problems that required skill.

<Problems to be solved by the invention> The present invention was made in view of the above-mentioned problems in the past, and it is possible to easily adjust the aiming without requiring any special equipment, equipment, or skill. It is an object of the present invention to provide an automobile headlamp that can perform the following functions.

<Means for solving the problem> The vehicle headlamp of the present invention that achieves the above purpose is:
In an automobile headlamp in which a reflector is installed in the light body so that the aiming can be freely adjusted, an observation window is formed in the light body or the front lens, and the amount of aiming in the vertical direction of the reflector is observed in the reflector. The present invention is characterized in that a level is installed at a position that can be seen from the observation window, and a scale is formed on the observation window for observing the amount of movement of the level in the left and right direction.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

In the figure, reference numeral 1 denotes a lamp body, within which a reflecting mirror 2 is installed via an aiming mechanism so that aiming can be freely adjusted, and a front lens 3 is installed in the front opening of the lamp body 1.

As the aiming mechanism, a conventionally known aiming mechanism may be employed. In the illustrated embodiment, the lamp body 1
The pivot 4 protruding from the side is connected to the pivot receiver 5 attached to the mounting stay 21 of the reflector 2 to form a fulcrum part, and the two moving point parts for vertical aiming and left/right aiming are attached to the mounting stay 21 of the reflector 2. Stay 22
The tip end 7a of the aiming screw 7 is connected to the support member 6 attached to the lamp body 1, and the screw part 7b of the aiming screw 7 is screwed to the gear unit 8 attached to the lamp body 1, and the input operation lever of the gear unit 8 is connected. The aiming screw 7 is rotatably operated via the arrow 9 to adjust the aiming of the reflecting mirror 2.

The lamp body 1 or the front lens 3 is provided with an observation window 11 for observing a level 10, which will be described later.
Install it in a location where it can be seen from.

When the observation window 11 is formed in the lamp body 1, the observation window 11 is formed by, for example, hollowing out the upper wall 1a of the lamp body 1 to an appropriate size to form an opening and covering it airtightly with a transparent cover plate 11a. When forming the lens 3, a part of the upper wall 3a that does not affect the light distribution performance is formed into a transparent transparent shape, so that the spirit level 10 placed on the reflector 2 can be seen from the upper part of the outside of the headlight. It is configured as follows. Also, in this observation window 11, a level 10 installed on the reflecting mirror 2 moves in the left-right direction (arrow H) in unison with the aiming operation of the reflecting mirror 2, that is, in the left-right direction of the reflecting mirror 2. A scale 12 is formed for observing the amount of aiming.
At this time, the scale 12 may be formed only on the transparent cover plate 11a constituting the observation window 11, or only on the lamp body 1 side, or may be formed on the cover plate 11a as in the illustrated embodiment.
It may also be formed over the lamp body 1.

The spirit level 10 is for observing the vertical aiming amount of the reflecting mirror 2, and like a normal spirit level, it has a mark (bubble) 10a and a vertically long center line 10.
b and a scale 10c, and is positioned directly below the observation window 11 and fixedly installed on the upper wall 2a of the reflecting mirror 2. At this time, the level 10 is installed so that its longitudinal direction coincides with the front-rear direction of the reflecting mirror 2, and is positioned on the opposite side of the aiming fulcrum with respect to the center of the reflecting mirror 2 (line L in FIG. 1). In addition, it is preferable to install it so as to be located near the top and bottom of a horizontal plane that includes the aiming fulcrum. By installing the spirit level 10 in this manner, the amount of vertical aiming movement of the reflecting mirror 2 can be observed with higher sensitivity and less error.

Therefore, the aiming of the headlamp of the present invention is adjusted in advance by the lamp manufacturer, and then the aiming screw 7 is rotated in the forward and reverse directions after being assembled into the vehicle by the automobile manufacturer to adjust the aiming of the reflector 2. Let's do it. At this time, first rotate the vertical aiming screw 7 in the vertical direction (direction of arrow V).
After the aiming adjustment is completed, look at the level 10 installed on the reflecting mirror 2 from above the observation window 11, and check the mark (bubble) 1 on the level 10.
Mark the position of 0a on the observation window 11 (marking) 1
3, then rotate the left and right aiming screw 7 to adjust the aiming in the left and right direction (in the direction of arrow H). After completing the aiming adjustment, move the spirit level 10 installed on the reflector 2 to the observation window 11. A marking 14 is placed on the scale 12 that coincides with the center line 10b of the spirit level 10 when viewed from above. Therefore, from now on, the level 10 installed on the reflecting mirror 2
Vertical aiming adjustment can be performed simply by matching the mark (bubble) 10a of the mark 10a with the mark 13 marked on the observation window 11. Aiming adjustment in the left and right direction can be performed simply by matching the mark 14 with the mark 14.

<Effect of the invention> Since the automobile headlight of the invention is constructed in this way,
Vertical aiming adjustment can be performed using a spirit level installed on the reflector, and horizontal aiming adjustment can be made by simply aligning the spirit level (center line) with the scale (mark) formed on the observation window. Aiming adjustment can be easily carried out without requiring any special equipment or skill.

Therefore, the intended purpose can be achieved.
