DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for mounting a vehicle headlamp.

(Conventional technology) A joint (outline) between a headlamp and a front fender (hereinafter, referred to as a fender) is a prominent part in the appearance of a car, and affects the texture of the car. To increase the assembly accuracy of this headlamp and fender, high-precision processing is required for the headlamp, fender and assembly product,
There is a technical difficulty that high-precision processing requires a large amount of cost for manufacturing a mold, and there is a trade-off between the texture of the product and the cost.

Conventionally, as shown in FIG. 4, the head lamp 1 and the fender 2 are assembled by using bolts 3 provided on the back surface of the holder 1a of the head lamp 1 (see also FIG. 5).
The nut 6 is screwed into the hole 5 of the lamp support panel 4, and the nut 6 is screwed and temporarily tightened. After positioning, the nut 6 is tightened and fixed. In addition, as shown in FIG. 6, a bolt 3 (see also FIG. 7) provided on the back surface of the holder 1a is inserted into the hole 5 of the lamp support panel 4 and the nut 6 is temporarily tightened to position in the left-right direction. Further, the lamp support portion 7 provided on the head lamp 1 and the upper member 8 connected to the lamp support panel 4 are temporarily tightened with bolts 9 and nuts 10 to position the head lamp 1 in the vertical direction. The headlamp 1 is fixed to the lamp support panel 4 by retightening the bolts 9 and the nuts 10.

A small hole 11, a large hole 12, a horizontal long hole 13, and a vertical long hole 14 as shown in FIG. 8 are formed in the lamp support panel 4 to which the headlamp 1 is attached. The headlamp 1 is rotated with reference to the small hole 11 irrespective of the position of the small hole 11, and the large hole 12, the horizontal long hole 13, and the vertical long hole 14 regulate up, down, left and right directions, and the components are within the respective allowable ranges. Adjust for variations.

Further, as shown in FIG. 9, a clip 15 (see also FIG. 11) protruding inward is provided on the rear side surface of the holder 1a of the headlamp 1 and a fastener 16 is provided on the fender 2 side, as shown in FIG. (See FIG. 10), and the headlamp 1 is fixed to the fender 2 by assembling these clips 15 and fasteners 16 as shown in FIGS. 12 and 13.

As a mounting structure of a headlamp for a vehicle, there are ones disclosed in Japanese Utility Model Laid-Open No. 60-75136 and Japanese Utility Model Laid-Open No. 63-114844. Japanese Utility Model Publication No. 60-75136 discloses a mounting flange formed by bending the front end portion of a front fender panel inward, and locating a hole located in the mounting flange at a position outside the rear surface of the lamp via a pin fastener. , A spherical locking portion at the tip of the locating pin protruding rearward is rotatably inserted, and further,
The radiator core panel as a lamp mounting panel
A long hole is formed, and a bolt protruding rearward is inserted into the inside of the rear surface of the headlamp to absorb a mounting error at the time of mounting. Also,
In Japanese Unexamined Utility Model Publication No. 63-114844, a positioning member is formed on the back surface of the lamp assembly, and a positioning hole for fitting the projection is formed on the lamp mounting surface to position and fix the two.

In addition, the position adjustment position of the headlamp
There is one disclosed in JP-A-115944. The one disclosed in this publication has a pivot shaft provided on a headlamp body pivotally attached to a pivot holder movably housed in a case mounted on a vehicle body, and adjusts the position of the headlamp and the vehicle body. It is.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional technology, the one shown in FIGS. 4 and 6 has a head lamp attached to a lamp support panel screwed to a fender irrespective of the fender. The headlamp is indirectly aligned with the fender.

As a result, the quality of the alignment between the fender and the headlamp depends on the assembling accuracy of the fender and the lamp support panel. To achieve a good alignment, the fender and the lamp support panel are integrated. High assembling accuracy is required. However, in general, the front fender is often damaged, and is often detachably screwed to a lamp support panel or the like for restoration and replacement, and high assembly accuracy cannot be expected.

As described above, the accuracy of assembling the fender and the lamp support panel cannot be expected, and if there is a variation in the assembly, the alignment between the head lamp mounted on the lamp support panel and the fender also varies depending on the variation. This causes a problem that it is difficult to adjust the gap between the fender and the lamp to the designed distance, for example. further,
In order to improve the assembling accuracy of the fender and the lamp support panel, a high-precision metal mold is required, and there is a problem that the number of manufacturing steps is increased and the cost is increased.

Further, when the fender and the headlamp are fixed by a clip as shown in FIG. 9, the position of the fender and the headlamp can be easily adjusted, but since the clip is fixed to the headlamp, the headlamp can be fixed. The position is determined only by the position of this clip both up and down, left and right, and conversely, the relationship between the headlamp bolt and the mounting hole of the lamp support panel becomes strict, that is, the adjustment range becomes narrow and assembly becomes difficult Problems arise. In order to assemble securely, high processing accuracy is required for clip mounting position, fastener mounting position, fender processing,
There is a possibility that the cost will increase.

The one disclosed in Japanese Utility Model Publication No. 60-75136 has one end of the headlamp rotatably fixed to the fender,
That is, since the head lamp and the fender are fixed in association with each other, there is a problem that the adjustment range between the head lamp and the fender is narrowed. Further, the one disclosed in Japanese Utility Model Laid-Open No. 63-114844 also has a problem that the adjustment range is similarly narrowed because the fender and the headlamp are fixedly positioned. Furthermore, the one disclosed in Japanese Utility Model Application Laid-Open No. 62-115944 has a complicated structure, and does not directly position the headlamp and the fender in association with each other, but has a low degree of freedom in adjustment.

The present invention has been made to solve the above-described problem. The fender and the headlamp are positioned by associating with each other by abutting, and the assembling accuracy of the headlamp and the fender is increased, thereby improving the texture and improving the manufacturability. It is another object of the present invention to provide an automobile headlamp mounting device with improved assemblability.

(Means for Solving the Problems) As a means for solving the above problems, the present invention is to form a flange portion by bending a front end portion of a fender inward and to provide a lamp support panel for mounting a head lamp on the fender. The rear of the headlamp holder is provided with a rib and a bolt protruding rearward, and a long hole-like insertion hole through which the bolt is inserted is formed in the lamp support panel by the number of bolts. The side part is in contact with the tip of the flange part.

(Operation) In the present invention, the front end of the fender is bent inward to form a flange, and the side of the rib protruding from the back of the head lamp holder of the flange at the time of assembling the head lamp is used. The head lamp and the fender are associated with each other without fixing the rib and the flange portion, and the mating surfaces of the fender and the head lamp are positioned so as to smoothly and coincide with each other.

Further, the lamp support panel for mounting the head lamp connected to the fender is provided with a plurality of elongated insertion holes corresponding to the number of bolts protruding from the back of the head lamp holder. When assembling,
The movement of the bolt inserted into the insertion hole is allowed, and the trouble at the time of processing each of the bolt and the flange is adjusted.
That is, when assembling the headlamp, the positions of the headlamp in the vertical and horizontal directions are adjusted to ensure that the mating surfaces of the fender and the headlamp are aligned.

(Embodiment) An embodiment of the present invention will be described below with reference to FIG. The figure shows the mounting state of the head lamp and the fender, and shows only one side for convenience. In the figure, the lower side is the front part of the car. In the figure, what is indicated by reference numeral 17 is an automobile fender. At the tip of the fender 17, a flange portion 18 bent inward is formed.
A lamp support panel 19 screwed to the fender 17 (not shown) is provided behind the flange portion 18. Lamp support panel 19 has lamp support panel
A headlamp in which a bolt 21 is inserted through an insertion hole 20 of 19 and a rib 22 is in contact with a flange portion 18 via a cap 23
24 is fixed by a nut 25 screwed to the bolt 21.

The back part of the headlamp 24 will be further described. The rear side of the headlamp 24 is a holder 26,
On the back of 26, four bolts 21 are provided, two on each side, as shown in FIG. The upper and lower two ribs are provided between the bolt 21 on the side of the fender 17 and the side edge of the holder 26.
22 is formed integrally with the holder 26. A rust prevention cap 23 is attached to the rib 22. The shape of the insertion hole 20 formed in the lamp support panel 19 is a horizontal slot as shown in FIG. The lamp support panel 19 has four insertion holes 20 formed therein. Since the insertion hole 20 has a long hole shape, the bolt 21 of the headlamp 24 is easily inserted at the time of assembly.

With the above configuration, when assembling the headlamp 24 to the lamp support panel 19, the holder of the headlamp 24 is required.
26, the bolt 21 is inserted into the insertion hole 25 formed in the lamp support panel 19, the head lamp 24 is slid outward, and the rib 22 and the flange portion 18 are brought into contact via the cap 23. If the nut 25 is tightened and fixed, the fender 17 and the headlamp 24 are not fixed, but can be associated with each other only by being brought into contact with each other. Further, since the step between the fender 17 and the headlamp 24 can be determined by the length of the flange 18, the step can be easily eliminated by managing only the length of the flange 18.

(Effects of the Invention) In the present invention, as described above, the flange of the fender and the rib of the headlamp are positioned in contact with each other, and the assembling accuracy of the headlamp and the fender is increased. Variations in the left and right steps from the headlamp are reduced, and the texture can be improved. Further, by making the rib and the flange portion abut, the adjustment range of the headlamp is widened, and the degree of freedom of adjustment can be increased. In addition, the accuracy of assembling the fender and the headlamp is high, the complicated mold is not required, the cost of the mold is not required, and the productivity is improved. Further, since the rib of the headlamp and the flange of the fender are integrally formed from the respective parts, dimensional accuracy is more easily obtained than when another member is used, thereby improving the manufacturability. Further, another member necessary for the headlamp is only a cap to be mounted on the rib, so that it is possible to suppress an increase in cost and to be economical.
