Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to an aiming structure of a headlamp for automobiles including motorcycles.

<Prior Art> As shown in FIGS. 4 and 5, the conventional aiming structure of an automobile headlamp includes a fulcrum 3 formed at, for example, the upper right side of a rim 2 attached to the outer periphery of a lamp unit 1. A screw 4 for horizontal aiming is connected to the upper left position, and a screw 5 for vertical aiming is connected to the lower right position. In such a conventional aiming structure, the lamp unit A connects the rim 2 and the fulcrum parts 3 and 2.
Since only the aiming screws 4 and 5 are supported on the vehicle body side in a hanging manner, they tend to be weak against vibration and lack strength, and the optical axis tends to shake after adjustment. Moreover, as shown in FIG. 5, it is necessary to ensure a gap 6 for aiming between the lamp unit 1 and the rim 2, and aiming components are arranged around the outer periphery of the lamp unit. Therefore, the entire headlamp becomes large and requires a large installation space on the vehicle body, and the momentum lamp unit itself has to be made smaller to accommodate the limited installation space, which is an inconvenience.

<Problems to be solved by the invention> The present invention was devised in view of the inconveniences and shortcomings of the conventional structure, and it is possible to reliably and firmly support the lamp unit and improve vibration resistance and strength. It is an object of the present invention to provide an aiming structure for an automobile headlamp, which eliminates the need for a rim for supporting a lamp unit and thereby allows the entire headlamp to be made smaller.

<Means for Solving the Problems> The aiming structure of the vehicle headlamp of the present invention that achieves the above purpose is such that the upper center of the lamp unit is connected to the vehicle body side with a single screw to form a fulcrum part.
A bracket with an arm is attached to the lower part of the lamp unit located on the axis of the fulcrum part so as to be horizontally rotatable with one shaft screw, and the shaft screw is attached to the lower part of the arm or the lamp unit. An arcuate hole is formed at the center, and an aiming screw is connected between the lamp unit and the arm through the arcuate hole, so that the lamp unit can be aimed in the left and right directions, and the bracket is fixed to the support leg on the vehicle body side. The lamp unit is connected with a real aiming screw, and an arcuate hole through which the aiming screw is inserted is formed in the bracket or support leg in an arc shape centered on the fulcrum part, so that the lamp unit can be aimed in the vertical direction. That is.

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

The lamp unit 1 is constructed in the same manner as the conventional lamp unit, and is fixed to the housing 7 or the adjusting metal by appropriate means. In the following description, the lamp unit, the housing 7, and the adjusting metal will be simply referred to as the lamp unit 1.

The lamp unit 1 is supported on the vehicle body side at its upper center position and lower center position so as to be able to aim freely in the left and right and up and down directions.

The fulcrum part 8 that supports the lamp unit 1 so that it can be aimed freely in the horizontal and vertical directions is
The upper center position of the vehicle body side 9 is connected to the vehicle body side 9. That is, the fulcrum part 8 directly connects the upper center position of the lamp unit 1 to the vehicle body side 9 with one screw 10, and also connects the screw 10 and the lamp unit 1 to the vehicle body side 9 directly.
A rubber damper 11 is interposed between the lamp unit 1 and the lamp unit 1 so as to correspond to the aiming operation of the lamp unit 1.

In addition, a bracket 12 is attached to the lower center position of the lamp unit 1, and the bracket 1
2 to support legs 13 on the vehicle body side, and supports the lamp unit 1 so as to be able to aim horizontally and vertically with respect to the vehicle body.

The bracket 12 is for directly supporting the lamp unit 1 and at the same time supporting the lamp unit 1 in a freely aiming manner.The bracket 12 is formed in the shape of a gate on the front, and its horizontal portion 12a is located at the lower central position of the lamp unit 1, more specifically, at the fulcrum. The lamp unit 1 is mounted on the lower part of the lamp unit 1 located on the axis of the section 8 with a single shaft screw 14 so as to be rotatable in the horizontal direction, and the left and right vertical sections 12b are attached to the support legs 1 fixed to the vehicle body side 9.
3 and one aiming screw 15 are connected to each other so as to be movable up and down in the front and rear directions. Also, bracket 12
The lamp unit 1 is installed horizontally in the horizontal part 12a of the lamp unit 1.
an arm 12' is integrally extended along the lower part of the
An arcuate hole 17 centered around the shaft screw 14 is formed in the lower part of the arm 12' or the lamp unit 1, and an aiming screw 16 is inserted into the arcuate hole 17, and the aiming screw 16 is used to hold the arm 12'. and the lower part of the lamp unit 1 are connected to each other, so that the lamp unit 1 can be freely aimed in the left and right directions. Also, bracket 12
The left and right vertical parts 12b or the support legs 13 have an arcuate hole 18 through which the aiming screw 15 is inserted.
is formed in an arc shape centered on the fulcrum portion 8, so that the lamp unit 1 can be freely aimed in the vertical direction.

Therefore, when adjusting the aiming of the lamp unit 1 in the left and right direction relative to the vehicle body, the lamp unit 1 can be adjusted by loosening the screws 14 and 16 that connect the lamp unit 1 and the bracket 12.
The lamp unit 1 can be freely rotated left and right around the screw 14, more specifically around the line connecting the screw 14 and the screw 10 of the fulcrum 8, so stop the lamp unit 1 at a desired position and remove the screw 14 and screw again. All you have to do is tighten 16. When adjusting the aiming in the vertical direction, the lamp unit 1 can be adjusted by loosening the screw 15 connecting the bracket 12 and the support leg 13.
Since it can move freely in the vertical direction around the fulcrum part 8, it is sufficient to stop the lamp unit 1 at a desired position and tighten the screw 15 again.

<Effects of the invention> Since the aiming structure of the automobile headlamp of the invention is constructed in this manner, it is possible not only to easily and accurately adjust the aiming, but also to ensure that the lamp unit is firmly supported against the vehicle body. It is possible to improve the performance, vibration resistance, and strength.

That is, in the conventional structure, the lamp unit was supported on the vehicle body side including the housing in a hanging manner by an aiming component such as an aiming screw, but in the structure of the present invention, the lamp unit is directly supported by a metal fitting attached to the vehicle body side. Therefore, the lamp unit can be firmly and securely supported against the vehicle body.

Furthermore, since there is no need for a rim to support the lamp unit, an expensive aiming screw, or a self-locking nut, parts costs can be reduced, and ease of assembly is improved, resulting in significant cost reductions. It is possible to expect. That is,
Conventionally, the aiming component that supports the lamp unit so that it can be aimed freely and the mounting component that attaches the headlight to the vehicle body were separate, but in this proposal, both are used for the same purpose, so the number of parts can be reduced overall. This means that it can be reduced.

Further, according to the proposed structure, there is no need for a rim to support the lamp unit, and furthermore, since no aiming component is arranged around the outer periphery of the lamp unit,
The entire headlamp can be made smaller, and if the installation space on the vehicle body is the same, the lamp unit can be made larger accordingly.

Therefore, the intended purpose can be achieved.
