Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a protector mounting structure which is interposed so as not to damage an exterior plate of a vehicle body when the vehicle lamp is mounted on the vehicle body.

[Conventional technology]

FIG. 2 is a sectional view of a vehicular lamp equipped with a protector mounting structure of a conventional example.

The vehicle body exterior plate 1 is provided with an opening 1a for mounting a lamp, and a stepped portion 1b is formed around the opening 1a.

The main body of the lamp housing 2 is fitted into the opening 1a.

A flange portion 2a is formed around the front opening portion of the lamp housing 2, and the flange portion faces the periphery of the lamp fitting mounting opening portion 1a (inside the stepped portion 1b) of the vehicle body exterior plate, and the packing 7 Abut through.

A front lens 3 is attached to cover the front opening of the lamp housing 2.

A bulb socket 4 is installed through the vicinity of the center of the lamp housing, and a light source bulb 5 is mounted.

Reference numeral 6 is a reflector provided inside the lamp housing 2.

A protector 8 made of a flexible material is interposed between the periphery of the front lens 3 and the vehicle exterior plate 1 (outside the stepped portion 1b).

FIG. 3 shows enlarged details of the vicinity of the protector 8.

Around the front lens 3, the lamp housing flange 2a
The side surface (the right side in the figure) of the outer periphery of the outer peripheral surface of the outer peripheral surface of the base plate 3 is protruded to face the exterior plate 1 to form the protruding surface 3a.

An adhesive layer 9 is formed between the projecting surface 3 a and the protector 8 and the protector 8 is bonded to the front lens 3.

[Problems to be solved by the device]

In the protector mounting structure of the above-mentioned conventional example, (a) the area where the adhesive layer 9 can be formed is limited by the size of the overhanging surface 3a formed on the back surface of the front lens 3 and cannot be made very wide. No adhesive strength can be obtained.
If the adhesive strength is insufficient, there is a risk that the protector 8 may be displaced in the direction in which it comes out (to the right in the drawing).

(B) If the amount of the adhesive applied to the overhanging surface 3a is too large, there is a risk that the adhesive will come out as shown by the arrow a and the appearance will be impaired.

(C) When the front lens 3 is colorless and the adhesive layer 9 is colored, the color tone of the adhesive layer appears in the external appearance, and the appearance is not good.

The present invention has been made in order to solve the above-mentioned problems, and (a) a sufficient adhesive area can be obtained, (b) there is no possibility that the adhesive that has come out will damage the appearance, and (c) adhesive An object of the present invention is to provide a protector mounting structure in which the color tone of the agent does not appear in the appearance through the front lens, and (d) the protector and the packing are not displaced with respect to the lamp housing.

[Means for Solving the Problems]

The structure of the present invention will be described below with reference to FIG. 1 corresponding to the embodiment.

In the protector 10 according to the present invention, a portion 10a shown in the drawing is a portion which is sandwiched between the overhanging surface 3a of the front lens and the vehicle body exterior plate 1 and receives pressure, and corresponds to the protector 8 of the conventional example. Is.

In the present invention, the pressure receiving portion 10a is extended to the inside (left side in the figure) of the outer periphery of the lamp housing flange portion 2a to form an extension portion 10b, and this extension portion is provided on the rear surface (projection portion) of the lamp housing flange portion 2a. Figure behind the light direction
Face the bottom surface in this figure) and extend this extension
10b is sandwiched between the lamp housing flange portion 2a and the packing 7, the lamp housing flange portion 2a and the protector extension portion 10b are adhered, and the protector extension portion 10b is attached.
And the packing 7 are bonded.

[Action]

(A) According to the above configuration, the bonding surface (the surface on which the adhesive layer 11a is formed) can be wide, and sufficient bonding strength can be obtained.

(B) Even if the adhesive comes out from the adhesive surface, it does not appear in the appearance, so there is no fear of impairing the appearance.

(C) Since the adhesive layer is formed apart from the front lens (on the back side of the lamp housing flange portion), there is no possibility that its color tone will appear in appearance.

(D) Since the protector and the lamp housing are bonded to each other and the protector and the packing are bonded to each other, there is no possibility that the protector and the packing are displaced from the lamp housing.

〔Example〕

FIG. 1 is a sectional view showing one embodiment of a protector mounting structure according to the present invention.

This embodiment is an improvement in which the present invention is applied to the mounting structure of the conventional example shown in FIG. 3, and the same reference numerals as those in FIG. Through are similar components.

The protector 10 according to the present embodiment includes a pressure receiving portion 10a that is compressed by being sandwiched between the overhanging surface 3a of the front lens 3 and the vehicle body exterior plate 1, and a lamp housing inside (left side in the figure) from the pressure receiving portion 10a. Extension part 10 extended to the back side of the flange part 2a
It is constructed integrally with b.

Then, the extension portion 10b is replaced with the lamp housing flange portion 2
Adhere the surfaces that overlap with a to each other to form an adhesive layer 11a.
In addition to the above, the extension portion 10b and the packing 7 are also adhered to form an adhesive layer 11b.

(A) In this embodiment, since the area of the adhesive layer 11a is larger than that of the overhanging surface 3a of the front lens, sufficient adhesive strength can be obtained and there is no risk of the protector 10 being misaligned. . Further, since the extension portion 10b of the protector 10 and the packing 7 are adhered to each other, there is no possibility that the packing 7 will be displaced.

(B) In addition, in this embodiment, even if the excess adhesive comes out from the portion where the adhesive layer 11a is to be provided, it does not flow out to the front side of the lamp or the exterior plate, so there is no risk of impairing the appearance.

(C) Furthermore, since the adhesive layer 11a of this embodiment is formed on the back surface of the flange portion 2a of the lamp housing (generally an opaque member), the color tone of the adhesive layer may appear in the appearance through the front lens. There is no.

[Effect of device]

As described above, according to the protector mounting structure according to the present invention, (a) a sufficient bonding area and bonding strength can be obtained, and the protector is displaced in the direction of the humming or the packing is displaced. There is no fear, (b) there is no fear that the appearance will be damaged even if the adhesive sticks out from the bonding surface, and (c) the color tone of the adhesive layer even if the adhesive layer is colored and the front lens is colorless. There is no danger of appearing in the appearance through the front lens.
