Description

[Detailed description of the invention] <Industrial field of application> The invention relates to automobile headlights, and more specifically, a movable member is attached to a fixed member side so that aiming can be freely adjusted, and the vertical aiming amount of the movable member is adjusted. This invention relates to a headlamp for an automobile that can be observed using a spirit level installed on the side of a movable member.

There are two types of aiming adjustment methods for automotive headlights: a movable reflector type that moves the reflector relative to the lamp body, and a movable unit type that moves the lamp unit relative to the housing or vehicle body. are the same, and in this specification, a movable member such as a reflector or a lamp unit is referred to as a movable member, and a member such as a lamp body, housing, or vehicle body that supports the movable member is referred to as a fixed member.

<Prior art> In headlights for automobiles, vertical aiming adjustments are made while observing a spirit level installed on the movable member side. Due to installation errors and assembly errors to the vehicle body, the bubble in the spirit level installed on the movable member side may move to an extreme position, making it impossible to perform aiming adjustment.

<Problem 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 move and adjust the position of the bubble of the spirit level installed on the movable member side to an appropriate position. The aim is to provide headlights for automobiles.

<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 movable member is assembled to a fixed member side so that aiming can be freely adjusted, a level is installed on the movable member side for observing the amount of aiming in the vertical direction, and the level and the movable member are connected. The feature is that an elastic adjustment member is interposed between the two.

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

1 to 5 show an embodiment of a movable unit type headlamp in which the movable member A is the lamp unit 1 and the fixed member B is the housing 2, and FIGS. 6 to 8 show the movable member A. 1 shows an embodiment of a headlamp of a movable reflector type in which the figure is a reflector 3 and the fixed member B is a lamp body 4, and common constituent members are designated by the same reference numerals throughout all the drawings. Furthermore, movable member A
As the aiming mechanism for freely adjusting the aiming toward the fixed member B side, a conventionally known mechanism can be adopted, and a description of its specific structure will be omitted here.

Therefore, a level C for observing the amount of aiming in the vertical direction is installed on the movable member A, and
An elastic adjustment member D is interposed between the spirit level C and the movable member A.

The level C, like a normal level, has a bubble tube 6 housed in a case 5 and an observation scale 7 formed on the top surface of the bubble tube 6, and is fixedly installed on the top surface of the movable member A. do. At this time, the level C is installed so that its longitudinal direction coincides with the optical axis direction of the movable member A, and the elastic adjustment member D is interposed between it and the movable member A.

The elastic adjustment member D is designed to prevent air bubbles from the level C installed on the movable member A side due to molding errors and assembly errors of each component of the headlight, including the level C, and installation errors to the vehicle body. 8 is not in the proper position, the bubble 8 is moved and adjusted to the proper position by moving the level C, and the level is inserted between the level C and the movable member A. C is supported so that it can swing up and down and/or left and right. That is, the embodiments shown in FIGS. 1 to 3 are as follows:
An example is shown in which the elastic adjustment member D is a coil spring, and flanges 9a and 9b are provided protruding from the side wall 5a and rear wall 5b of the spirit level C, respectively.
Elastic adjustment members (coil springs) D are interposed between a and 9b and the upper surface of the movable member A, respectively, and are attached using screws 10a and 10b. Therefore, in the case of this embodiment, by rotating the screw 10a of the flange 9a protruding from the side wall 5a of the level C in the forward and reverse directions, the level C can be adjusted by the elastic action of the elastic adjustment member (coil spring) D. The screw 10b of the flange 9b that can be swung in the left and right direction and protrudes from the rear wall 5b side of the spirit level C
By rotating forward and backward, the level C can be similarly swung up and down, and as a result, the bubble 8 of the level C can be moved and adjusted to an appropriate position. Further, the embodiments shown in FIGS. 4 to 8 show examples in which the elastic adjustment member D is a plate spring, and flanges 9b and 9c are protruded on the rear wall 5b and front wall 5c of the spirit level C, respectively. The front flange 9c is engaged with the engagement hole 11 formed protruding from the movable member A side, and an elastic adjustment member (plate spring) D is interposed between the level C and the movable member A. , the flange 9b on the rear wall 5b side of the spirit level C is attached to the movable member A together with the elastic adjustment member (plate spring) D with screws 10b. Therefore, in the case of this embodiment, by rotating the screw 10b forward and backward, the level C is swung vertically by the elastic action of the elastic adjustment member (plate spring) D, and the bubble 8 of the level C is You will be able to move and adjust it to the appropriate position.

In particular, in the case of a movable reflector type headlight, the movable member (reflector 3) A on which the level C is installed is housed within the fixed member (light body 4) B, so the level C cannot be installed externally. The level C is installed at a position where it can be seen from the top surface of the front lens 12 as in the embodiment shown in FIGS. 6 and 7, or is movable as in the embodiment shown in FIG. An arm 13 formed integrally or separately from a member (reflector 3) A is made to protrude from a fixed member (light body 4) B, and a level C is installed on the arm 13. At this time, in the case of the former (the embodiment shown in FIGS. 6 and 7), the elastic adjustment member D and screw 10b for swinging the level C are also accommodated in the fixing member (light body 4) B. Therefore, an insertion hole 14 for inserting the screwdriver E is formed on the B side of the fixing member (lamp body 4), and the insertion hole 14 is opened.
A screwdriver E is inserted through the hole to rotate the screw 10b, and the insertion hole 14 is closed with a rubber bushing 15 when not in use. Also, the latter (the embodiment shown in Fig. 8)
In this case, in order to ensure waterproofness between the fixing member (lamp body 4) B and the arm 13, a rubber bush 16 is interposed between the two.

<Effects of the invention> Since the automobile headlight of the invention is constructed in this way,
Even if there is a molding error or an assembly error of each component, or an assembly error in the vehicle body, the position of the bubble of the spirit level installed on the movable member side can be easily moved and adjusted to an appropriate position.

Therefore, the intended purpose can be achieved.
