Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a left headlamp section or a right headlamp section, in which each of the left and right headlamp sections of a vehicle is composed of two headlamp units arranged adjacent to each other. The present invention relates to a vehicular lamp structure in which each of the two headlamp units constituting the above is configured to be adjustable in the optical axis direction.

[0002]

2. Description of the Related Art Each of the left and right headlight parts mounted on a vehicle has a basic structure including a front lens part, a headlight unit, a headlight unit support part, and the like. An optical axis direction adjustment mechanism for adjusting the vertical direction and the horizontal direction of the optical axis of the lighting unit is provided. Vertical adjustment and horizontal adjustment of the optical axis of the headlamp unit are performed so that the irradiation range of the headlamp unit conforms to the regulations, and therefore the optical axis direction adjustment mechanism is
The direction of the optical axis of the headlight unit can be adjusted so that the irradiation range of the headlight unit according to the regulations can be obtained.

As an optical axis direction adjusting mechanism provided in a headlight portion of such a vehicle, for example, one disclosed in Japanese Utility Model Laid-Open No. 63-134842 has been proposed. Such an already proposed optical axis direction adjusting mechanism is such that the lower left end or the right end part of the headlight unit is attached to the vehicle body via the spherical bearing unit, and the upper part of the headlight unit is replaced by the spherical bearing unit. A mechanism for adjusting the optical axis direction of the headlamp unit up and down by rotating it about an axis extending in the left-right direction through the spherical bearing part at the lower left end or right end part of the headlamp unit. The headlamp unit is mounted on the vehicle body via the headlight unit by rotating the right portion or the left portion of the headlamp portion about an axis extending vertically through the spherical bearing portion. And a mechanism for adjusting the optical axis direction of the optical axis to the left and right.

Further, in the left and right headlight parts mounted on the vehicle, the left headlight part and the right headlight part are arranged adjacent to each other due to functional requirements or design requirements. It is also proposed that the headlight unit be formed by two headlight units. Then, in a headlight part formed by two headlight units,
For each optical axis of the individual headlamp units, vertical adjustment and horizontal adjustment are required to be performed. Therefore, for example, as described above, Based on the same concept as in the case of the optical axis direction adjusting mechanism that rotates and adjusts the optical axis direction up and down and left and right, they are arranged adjacent to each other to form the left headlight section or the right headlight section. For each of the headlight units, a mechanism for vertically adjusting the optical axis direction by rotating the headlight unit about an axis extending in the left-right direction,
A mechanism for adjusting the optical axis direction to the left and right is provided by rotating it about an axis extending vertically.

[0005]

As described above, when the left headlight part and the right headlight part are each formed by two headlight units arranged adjacent to each other, the left headlight part is formed. Alternatively, the two are arranged adjacent to each other to form the right headlamp section.
For each of the headlight units, by rotating it about the axis extending in the left-right direction,
In the case where a mechanism for adjusting the optical axis direction up and down and a mechanism for adjusting the optical axis direction to the left and right by rotating the axis about the axis extending in the vertical direction are provided. The respective configurations of the left headlight section and the right headlight section become extremely complicated with an independent optical axis direction adjusting mechanism for each of the two headlight units, and accordingly, Assembling and adjusting work of the headlight unit is complicated, and manufacturing costs increase.

In view of the above point, the present invention provides two headlamp units, which are arranged adjacent to each other, as a unit for forming a left headlamp section or a right headlamp section mounted on a vehicle.
Based on a relatively simple structure, a vehicle lamp structure capable of being supported in a state where vertical and horizontal adjustments of the optical axis thereof are accurately performed by the optical axis adjusting means. The purpose is to provide.

The main holding member and the second light valve that constitutes the other of the two headlight units are held, and the main holding member and the second light valve can be rotated with a rotation center axis line extending in the left-right direction of the vehicle. And a sub-holding member attached to the holding member, and further causes the main holding member to rotate about a rotation center axis extending in the left-right direction, thereby vertically moving the optical axes of the two headlight units. The first optical axis adjusting means for performing the adjustment and the main holding member are caused to rotate about a rotation center axis line extending in the vertical direction to adjust the left and right directions of the respective optical axes of the two headlight units. Second to do Made to perform the optical axis adjustment means, the rotation of with the rotation center axis line extending in the lateral direction sub-holding member,
Third optical axis adjusting means for performing vertical adjustment with respect to the other optical axis of the two headlight units is provided and configured.

[0008]

In the vehicular lamp structure according to the present invention configured as described above, one of the two headlamp units arranged adjacent to each other is supported by the main holding member, and The holding member is rotated by the first optical axis adjusting means with a rotation center axis extending in the left-right direction, and is rotated by the second optical axis adjusting means with a rotation center axis extending in the up-down direction. In addition, the other of the two headlamp units arranged adjacent to each other is supported by the sub-holding member, and the sub-holding member is attached to the main holding member to provide the main holding member. In addition to the rotation, the third optical axis adjusting means rotates about a rotation center axis extending in the left-right direction.
Then, the vertical adjustment of the optical axis of one of the two headlamp units arranged adjacent to each other with respect to the optical axis is performed by the first optical axis adjusting means and of the two headlamp units arranged adjacent to each other. Vertical adjustment of the other with respect to the optical axis is performed independently by the first optical axis adjusting means and the third optical axis adjusting means, respectively, and further, two headlamps arranged adjacent to each other. The horizontal adjustment of the optical axis of each unit is commonly performed by the second optical axis adjusting means.

By doing so, the first light valve constituting one of the two headlamp units is directly supported, and the other of the two headlamp units is constituted. The main holding member that supports the second light valve via the sub holding member and the three optical axis adjusting means (first, second and third optical axis adjusting means) are relatively simple. With such a configuration, each of the two headlamp units arranged adjacent to each other is reliably supported, and
The vertical direction adjustment and the horizontal direction adjustment regarding the optical axis required for each of the two headlamp units that are arranged adjacent to each other are accurately performed.
