[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a mounting structure for an automobile headlamp.

(Prior Art) Conventionally, there is a mounting structure for the above-mentioned headlamp as shown in FIG. 3, for example.

To explain this with a diagram, 21 is a front panel that forms the front of the car body, and the arrow in the diagram indicates
Fr indicates the front of the vehicle.

An opening 22 is formed in the front panel 21, and a headlamp 23 is fitted into the opening 22. The upper opening edge of the opening 22 has a cross section of approximately L.
The bent end of the bent portion 22a is further bent downward to form an inner flange 22b.
is formed.

Reference numeral 24 denotes a headlamp cover, and this headlamp cover 24 is in the form of a box with an opening at the front. This headlamp cover 24 covers the headlamp 23 from its rear side. A flange 24a formed at the upper front edge of the headlamp cover 24 is joined to an inner flange 22b of the opening 22, and both flanges 22a
b and 24a are welded together by spot welding. The reference numeral 26 in the figure is the welded part, and 27
is a sealer.

Further, a bent portion 22a of the opening 22 and a head lamp 23 facing the bent portion 22a are also provided.
Resin headlamp door 2 that covers the outer surface of the
8 is provided. That is, this headlamp door 2
8 covers the flanges 22b and 24a between the bent portion 22a and the headlamp 23, and the welded portion 26 thereof, thereby improving the appearance of this portion.

(Problem to be solved by the invention) By the way, in the above configuration, both flanges 22
If an attempt is made to spot weld b and 24a with a spot gun, it is necessary to sandwich both flanges 22b and 24a with the spot gun, so the width dimension W of both flanges 22b and 24a is required to be increased to some extent.

When the width W is increased in this way, it becomes necessary to also increase the width W' of the headlamp door 28 to cover it.

However, when the width dimension W' of the headlamp door 28 is increased in this way, the appearance weight of the headlamp door 28 relative to the headlamp 23 becomes larger, and the appearance of the two becomes unbalanced, resulting in a decrease in the appearance of this part. This causes the inconvenience of doing so.

(Purpose of the invention) This invention was made in view of the above-mentioned circumstances, and aims to improve the appearance of the headlamp mounting area by reducing the width of the headlamp door.

(Structure of the invention) The feature of this invention to achieve the above object is that the front edge of the headlamp cover is bent toward the inside of the vehicle body so that the cross section is approximately L-shaped, and this bent portion is joined to the inner surface of the edge of the opening having a substantially L-shaped cross section so as to be in surface contact with the inner surface of the opening, and is bonded with an adhesive.

(effect) The effects of the above configuration are as follows.

An opening 2 into which the headlamp 3 is inserted is formed in the front panel 1, and the front edge of a headlamp cover 7 covering the headlamp 3 is adhered to the opening edge of the opening 2 with adhesive. Regarding the connection of the front edge of the headlamp cover 7, it is no longer necessary to use a conventional welding spot gun. For this reason, opening 2
No structural restrictions are imposed on the connection between the opening edge of the headlamp cover 7 and the front edge of the headlamp cover 7 when using a spot gun. Therefore, to the extent that structural constraints are not imposed in this way,
Since the space between the bent portion 2a of the opening and the corresponding outer surface of the headlamp 3 can be made narrower, the width of the headlamp door 11 that covers the space between them can also be made smaller.

In addition, in the above connection, in this invention, the bent portion 2a of the opening 2 is bent into a substantially L-shaped cross section.
In order to correspond to this, the front end edge of the headlamp cover 7 is formed into a bent portion 7a having a substantially L-shaped cross section, and both of these bent portions 2a, 7a are joined so as to be in surface contact with each other and bonded with adhesive 8. The opening edge of the opening 2 and the front edge of the headlamp cover 7 are bonded together at two bonding surfaces that intersect at almost right angles (Example) An example of this invention will be described below with reference to FIGS. 1 and 2. explain.

In the figure, reference numeral 1 denotes a front panel made of sheet metal that forms the front of the vehicle body, and arrow Fr in the figure indicates the front of the vehicle body.

An opening 2 is formed in the front panel 1,
A headlamp 3 is fitted into this opening 2.
The headlamp 3 has a lamp housing 4 provided inside the front panel 1, and a lens 5 attached to the lamp housing 4 so as to cover the front opening of the lamp housing 4. In the above case, the lamp housing 4 is fixed to a stationary member of the vehicle body (not shown). Further, the lens 5 is fitted into the opening 2, so that the front surface of the front panel 1 and the front surface of the lens 5 are substantially flush with each other.

The upper opening edge of the opening 2 is bent rearward so that the cross section is approximately L-shaped, and this forms an upper bent portion 2a. Further, the bent end of this upper bent portion 2a is further bent downward. The lower opening edge of the opening 2 is bent rearward so that the cross section has an inverted substantially L-shape, and this forms a lower bent portion 2b.

Reference numeral 7 designates a headlamp cover made of sheet metal. This headlamp cover 7 is a box having an opening on the front side, and this headlamp cover 7 covers the headlamp 3 from the back side thereof. The front edge of the upper part of the headlamp cover 7 is bent rearward so that the cross section is approximately L-shaped, and this forms an upper bent portion 7a. and,
This upper bent portion 7a is joined to the inner surface of the upper bent portion 2a of the opening 2 so as to make surface contact with it, and is firmly adhered with an adhesive 8. This adhesive 8 is a structural adhesive, which also functions as a sealer, ie it seals between the upper folds 2a, 7a.

Further, the front edge of the lower portion of the headlamp cover 7 is bent downward, and this forms a lower bent portion 7b. The lower bent portion 7b is joined to the inner surface of the lower bent portion 2b of the opening 2 by spot welding. 9 is a sealer.

A headlamp door 11 is provided so as to frame the outer peripheral surface of the lens 5. The headlamp door 11 is made of resin and has an annular shape when viewed from the front, and covers the space between the opening edge of the opening 2 and the corresponding outer peripheral surface of the lens 5 to improve the appearance of this area.

An upper door 12 constituting the upper part of the headlamp door 11 is fitted between the upper bent portion 2a of the opening 2 and the upper surface of the lens 5. In this case, the upper bent portion 2a of the opening 2 and the lens 5
The gap between the upper door 12 and the upper surface is kept as small as possible, and therefore the width W of the upper door 12 is also small. Also, this upper door 1
2 has a vertical piece 12a, an upper door 12b and a lower piece 12c extending rearward from the upper and lower edges of this vertical piece 12a, and has a substantially U-shaped cross section, and the front side of the vertical piece 12a is It is substantially flush with the front surface of the front panel 1 and the lens 5. Further, elastic bodies 14 and 15 are attached to the rear ends of the upper door 12b and the lower piece 12c.

Similarly to the upper door 12, the lower door 13 constituting the lower part of the headlamp door 11 also has a vertical piece 1.
3a, an upper piece 13b, and a lower door 13c, and the elastic body 15 is attached to the rear end of the upper piece 13b.

A plurality of mounting pieces 17 are integrally molded on each of the lens 5 and the headlamp cover 7, and by screwing these mounting pieces 17 together with bolts, the headlamp door 11 can be attached to the headlamp 3 side. There is.

In the above case, a convex strip 18 is integrally molded on the entire outer peripheral surface of the lens 5, and the rear end of the lower piece 12c of the upper door 12 and the lower door 13
The rear end of the upper piece 13b is connected to the elastic body 15, respectively.
The entire surface of the protruding strip 18 is pressed against the front surface of the protruding strip 18 via the strip. Additionally, 19 is a front bumper.

The headlamp door 11 is a frame made of resin, which itself does not have sufficient rigidity and is relatively easily bent. However, as mentioned above, this is in pressure contact with the highly rigid headlamp 3,
Therefore, the headlamp door 11 maintains a predetermined shape. Further, in this case, the elastic body 15 is connected to the headlamp 3 and the headlamp door 11.
It absorbs the vibration that occurs between these two to prevent rattling between them.

When assembling the headlamp door 11 on the headlamp 3 side, this headlamp door 1
1 is brought into contact with the convex strip 18. Then, the overall shape of the headland door 11 can be maintained and positioned at the same time during this assembly. For this reason,
This assembly work can be done easily.

(Effects of the invention) According to this invention, since the space between the bent portion of the opening and the corresponding outer surface of the headlamp can be made narrower, the width of the headlamp door that covers the space between the two can also be made smaller. Therefore, the appearance of the headlamp door relative to the headlamp is prevented from becoming excessively heavy, thereby improving the appearance of the headlamp mounting portion.

By the way, when two flat plates are bonded together with an adhesive, the adhesive usually has a low tensile strength, so when the two flat plates separate from each other in the perpendicular direction, they will separate relatively easily. There is a risk of

Therefore, in this invention, the opening edge of the opening and the front edge of the headlamp cover are bonded at two bonding surfaces that intersect at almost right angles, and the bonding of these bonding surfaces compensates for each other against loads in all directions. prevent each other from peeling off. Therefore, the front edge of the headlamp cover is firmly connected to the opening edge of the opening.
