Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle headlamp mounting structure, and more particularly to a headlamp mounting structure in a large truck or the like.
[0002]
[Prior art]
For vehicles with a high vehicle height such as a large truck, as seen in Japanese Utility Model Publication No. 59-11033, for example, headlamps attached to the lower part of the front end of the cab are provided in openings provided near both ends of the front bumper. Or, as seen in Japanese Utility Model Publication No. 4-3880, headlamps attached to the outer surfaces of the front end portions of the side rails constituting the body frame face the openings provided near both ends of the front bumper. May reduce ground clearance.
[0003]
However, when the headlamps are attached to the lower part of the front end of the cab as in the former case, if the cab is float-supported with respect to the vehicle body frame to enhance the comfort, the height of the optical axis of the headlamp increases as the cab moves up and down. In either case, it is difficult to make the headlamp and front bumper openings correspond to each other with high accuracy in order to attach the left and right headlamps individually to the large cab or body frame. Further, there is a possibility that the appearance quality is deteriorated due to a positional deviation between the opening and the headlamp.
[0004]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and is compatible with the opening provided in the front bumper while attaching a headlamp to a vehicle body frame having a stable ground height to increase the stability of the optical axis. An object of the present invention is to provide a mounting structure that can improve accuracy and improve the appearance quality.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides a bracket fixed to the outer surface of the front end of the side rail that constitutes the vehicle body frame, left and right lamp stays fixed to both ends of a support member extending in the vehicle width direction, It has a front bumper with an opening . The left and right lamp holders joined together via a support member are fixed to the brackets, respectively, so that the headlamp attached to the lamp holder faces the opening from the back of the front bumper. Yes.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below in detail with reference to the drawings. 1 is a front view showing an embodiment of a vehicle having a headlamp mounting structure according to the present invention, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a cross-sectional view taken along line BB in FIG. 4 is an exploded perspective view of the main part.
[0007]
In these drawings, a vehicle body frame 2 on which a cab 1 of a cab-over-type truck is mounted is configured by connecting left and right side rails 3 and a cross member (not shown) in a ladder shape as in the case of a conventionally known ladder type frame. . Note that brackets 4 each having a flat T-shape are fastened and fixed to the outer surfaces of the front end portions of the side rails 3 by bolts (not shown).
[0008]
In addition, the lamp holder 6 is fastened and fixed to both ends of the support member 5 extending in the vehicle width direction in the vicinity of the front end of the vehicle body frame 2 with bolts 7, so that the left and right lamp holders 6 integrated in advance are attached to the front bumper 8. Corresponding to the openings 9 provided in the vicinity of both ends. The support member 5 is composed of an angle member that bends along the upper front portion and the upper front portion of the lamp holder as shown in the figure. For example, by adjusting the coupling position of the support member 5 and the lamp holder 6, While the lamp holder 6 is coupled and integrated with high rigidity, the left and right lamp holders 6 are made to correspond to the left and right openings 9 provided in the front bumper 8 with high accuracy, so that the headlamp 10 attached to the lamp holder 6 is attached to the front bumper 8. It faces the opening 9 from the back.
[0009]
The lamp holder 6 includes an attachment portion 6a to the support member 5 and a holding portion 6b that surrounds the periphery of the headlamp 10, and the headlamp 10 can be attached and detached as necessary. 6c is a headlamp mounting bolt provided on the holding portion 6b, 11 is a bolt that fastens and fixes the lamp holder 6 to the bracket 4, and 11a temporarily fixes the lamp holder 6 to the bracket 4 to improve alignment workability. On the other hand, after positioning, a positioning bolt for fastening the lamp holder 6 to the bracket 4 together with the bolt 11 and a bolt hole 12 are used, and the support member 5 is used as a holder for a harness (not shown) to the headlamp 10. is doing.
[0010]
That is, conventionally, since the left and right headlamps are attached to the cab or the vehicle body frame via the bracket, it is difficult to align the headlamp with the opening provided in the front bumper.
[0011]
However, in this embodiment, the left and right lamp holders 6 are integrated in advance via the support member 5 so that the lamp holders 6 correspond to the respective openings 9 of the front bumper 8 and then attached to the side rails of the vehicle body frame 1. The left and right lamp holders 6 (head lamps 10) integrated in advance via the support member 5 are attached to the body frame 2 as a unit, such as attaching the lamp holder 6 to the bracket 4 .
[0012]
For this purpose, the lamp holder 6 (headlamp 10) is installed in the opening 9 of the front bumper 8 without performing the position adjustment work as in the case where the left and right lampholders 6 (headlamp 10) are individually attached to the cab or the vehicle body frame. High accuracy can be achieved.
[0013]
Further, for example, the assembly width of the side rail 3 of the vehicle body frame 2 or the mounting position of the bracket 4 using an insertion gap secured between the bolts 11 and 11a and the bolt holes 12 for fastening and fixing the bracket 4 and the lamp holder 6 to each other. Therefore, it is not necessary to increase the accuracy of the assembly width of the side rails 3 more than necessary. Furthermore, since the left and right lamp holders 6 attached to the bracket 4 are coupled to each other via the support member 5, the support rigidity of the lamp holder 6 is increased.
[0014]
In addition, since the headlamp 10 is attached to the vehicle body frame 2, even when the cab 1 is float-supported on the vehicle body frame 2 to enhance the comfortability, the ground surface of the optical axis of the headlamp 10 accompanying the vertical movement of the cab is increased. There is no change in height and safety is increased.
[0015]
In the above embodiment, the support member 5 is formed of an angle member so as to ensure the positioning function and coupling rigidity of the left and right lamp holders 6, but the support member is formed of, for example, a pipe member or a channel member, or If necessary, the coupling rigidity and coupling accuracy of the left and right lamp holders 6 can be further increased by using two or more support members 5. In addition, the shapes of the bracket 4 and the lamp holder 6 are not limited to those shown in the embodiment, and may be anything as long as the headlamp 10 can be securely attached to the side rail 3 of the vehicle body frame 2.
[0016]
【The invention's effect】
As is apparent from the above description, the present invention is such that left and right lamp holders (headlamps) integrated in advance via a support member extending in the vehicle width direction are attached to the body frame as a unit. This eliminates the need for difficult position adjustment work, such as when attaching individual lamp holders (headlamps) to the cab or body frame, and increases the accuracy and strength of the headlamps and the appearance of the vehicle headlamps. Quality can be improved.
