Description

[Detailed description of the invention] <Industrial field of application> The present invention relates to an automobile lamp, and more specifically, an outer lens seal groove and an inner lens seal groove are formed surrounding the front opening of the lamp body, and each seal The present invention relates to an automobile lamp in which the outer lens and the inner lens are installed in parallel at the front opening of the lamp body by adhesively fixing the seal legs of the outer lens and the inner lens in the grooves with a sealant, respectively.

<Prior Art> In a conventional automobile lamp of this type, a pin or a protruding piece b is provided on an inner lens a, as shown in FIG. Inner lens a
This was done to prevent rattling and lifting of the surface. Therefore, when the light is not lit, the pin or protrusion b of the inner lens a can be seen through the outer lens c, and the outer lens seal groove e or the inner lens seal groove f of the lamp body d.
There was a problem in that the partition wall g between the lamp and the lamp could be seen through the outer lens c, spoiling the appearance of the lamp. This problem becomes noticeable when the outer lens is formed as a transparent lens without a lens step.

<Problem to be solved by the invention> The present invention has been made in view of such conventional problems, and it is an object of the present invention to simply and reliably prevent rattling and floating of the inner lens without using special parts. In addition, the inner lens can be easily installed in a predetermined position, and even if the outer lens is formed as a transparent lens without a lens step, the outer lens seal groove or the inner lens seal groove of the lamp body can be easily installed. It is an object of the present invention to provide a lighting device for an automobile that does not allow the partition wall between the two and the outer lens to be seen through the outer lens and has a good appearance when not lit.

<Means for solving the problem> The automotive lamp of the present invention that achieves the above purpose is:
A sealing groove for the outer lens and a sealing groove for the inner lens are formed surrounding the front opening of the lamp body, and the sealing legs of the outer lens and the inner lens are adhesively fixed to each sealing groove with a sealant, thereby forming the outer lens and the inner lens. In the automotive lighting device, the inner lens is provided with a peripheral wall that surrounds the peripheral edge of the inner lens, and a tip of the rising peripheral wall is directed outward to form a substantially U-shaped cross section. , the outer surface of the tip of the rising peripheral wall is brought into contact with the inner surface of the outer lens, and the tip of the partition wall that partitions the seal groove for the outer lens and the seal groove for the inner lens is abutted and fitted inside the tip of the rising peripheral wall. It is characterized by the combination of

<Example> Hereinafter, an example of implementing the present invention will be described based on the drawings.

The automotive lighting device of the present invention, like the conventional one, has a bulb 2 installed inside a lighting body 1 formed into a required shape, and a sealing groove 3 for an outer lens and a sealing groove 3 for an inner lens in the front opening of the lighting body 1. A seal groove 4 is formed around the entire circumference, and the seal legs 5a, 6a of the outer lens 5 and inner lens 6 are adhesively fixed to each seal groove 3, 4 with a sealant 7, thereby sealing the outer lens 5 and the inner lens. It is constructed by installing lenses 6 in parallel at the front opening of the lamp body 1.

The outer lens 5 may be formed in the same manner as before, and may be formed as a transparent lens without a lens step, or if necessary, a lens step may be formed on the inner surface, and the tip of the seal leg 5a on the periphery may be used for the outer lens of the lamp body 1. It is inserted into the seal groove 3 and fixed in an airtight manner with a sealant 7, and is installed in the front opening of the lamp body 1 in parallel with the inner lens 6.

The inner lens 6 has a lens step 61 formed thereon to obtain the required light distribution, and a seal leg 6a is integrally formed on the periphery of the lens step 61 to protrude toward the inner lens seal groove 4 of the lamp body 1. A peripheral wall 8 rising toward the lens 5 side is integrally formed and protrudes around the entire circumference, and the seal leg 6a is connected to the inner lens seal groove 4 of the lamp body 1.
The outer lens 5 is inserted into the outer lens 5 and fixed with adhesive using a sealant 7, and is installed in the front opening of the lamp body 1 in parallel with the outer lens 5.

The rising peripheral wall 8 of the inner lens 6 extends around the entire periphery of the inner lens 6 to the outer lens 5.
The outer surface 8 of the tip 81 is formed so as to protrude from the same body so as to come into contact with the inner surface 51 of the tip, and the tip 81 is formed to have a substantially U-shaped cross section toward the outside.
1a is in contact with the periphery of the inner surface 51 of the outer lens 5, and on the inner side 81b of the tip portion 81 is the tip of the partition wall 9 that partitions the outer lens seal groove 3 and the inner lens seal groove 4 formed in the lamp body 1. are fitted in contact with each other.

<Effects of the Invention> Since the automotive lamp of the present invention is configured in this manner, it has the following effects.

Since a rising peripheral wall is formed around the peripheral edge of the inner lens, the strength of the inner lens itself is increased, and deformation distortion can be kept small even if the inner lens is formed thin.

The tip of the rising peripheral wall faces outward and is formed into a substantially U-shaped cross section, and the outer surface of the tip comes into contact with the inner surface of the outer lens, so there is no need to use special parts to prevent rattling or lifting of the inner lens. This can be easily and reliably prevented, and even if the inner lens is somewhat distorted, the distortion can be corrected by the pressing force of the outer lens.

The tip of the partition wall that separates the outer lens seal groove and the inner lens seal groove formed on the lamp body is abutted and fitted inside the tip of the rising peripheral wall, so that the outer lens seal groove or partition is The wall rises and is obscured by the tip of the surrounding wall, and even if the outer lens is transparent without a lens step, it will no longer be visible through the outer lens, making it difficult to see the external appearance of the lamp when it is not lit. It can improve the appearance.

Moreover, the movement of the inner lens in the surface direction and depth direction of the lens is restricted by the inner surface of the outer lens and the partition wall of the lamp body, making it easy to position the inner lens in the surface direction of the lens. At the same time, the inner lens is not installed at an angle with respect to the depth direction of the seal groove of the lamp body, and the inner lens can be easily and accurately installed with respect to the lamp body.

Therefore, the intended purpose can be achieved.
