Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to automobile lamps such as motorcycle headlamps, and more specifically relates to an improvement in the mounting structure of a front lens to a lamp body.

<Conventional technology> Conventionally, when attaching the front lens to the lamp body,
A sealing groove is formed surrounding the front opening of the lamp body,
A sealing agent or packing material was loaded into the sealing compound, and the sealing leg of the front lens was inserted, and then the front lens was integrated into the lamp body using screws or C-shaped clips.

Therefore, there was a problem that the number of parts and assembly man-hours were large, leading to high costs.

<Problems to be solved by the invention> The present invention has been made in view of the above-mentioned problems in the past, and it is possible to assemble the front lens to the lamp body with one touch without using any special parts, and it also has a seal. To provide a lighting device for an automobile in which there is no risk of rainwater intruding into a lighting chamber from between a front lens and a lighting body even without using an agent or packing material.

<Means for Solving the Problems> The automotive lamp of the present invention that achieves the above purpose has a mounting flange extending around the outer periphery of the front opening of the lamp body, and engaging claws protruding from the upper left and right sides of the mounting flange. At the same time, hook pieces are protruded on the left and right sides of the lower part of the mounting flange, and a waterproof rib is protruded from the front lens to surround the entire front opening of the lamp body, and a peripheral side wall is provided on the outside of the waterproof rib. and an engaging hole into which the engaging claw of the light body is fitted and a hooking hole into which the hooking claw piece is inserted and engaged are formed in the peripheral side wall to integrate the front lens with the light body. It is characterized by what it did.

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

The lamp body 1 is molded into the desired shape using a resin material,
A mounting flange 3 that abuts or engages with the front lens 2 is integrally formed on the outer periphery of the front opening 1a, and an engaging claw 4 for engaging and fixing the front lens 2 to the mounting flange 3. and a hooking claw piece 5 is provided protrudingly.

The mounting flange 3 is formed to extend all around the outside of the front opening 1a of the lamp body 1, and the upper flange 3a is formed on the front opening 1a of the lamp body 1 at the tip surface 1'a.
It is formed in a more fully rearward position and extends outward,
The lower flange 3b is formed in the vicinity of the front end surface 1'a of the front opening 1a of the lamp body 1, projecting slightly forward, and the left and right flanges 3c are continuous between the upper flange 3a and the lower flange 3b. It is intended to be formed. Engagement pawls 4 are integrally formed to protrude from the upper portions of the left and right flanges 3c, and hooking pawl pieces 5 are integrally formed from the left and right portions of the lower flange 3b.

The engaging claw 4 is for engaging and fixing the upper part of the front lens 2, and has notches 6 formed on the left and right sides to provide elasticity, and the hooking claw piece 5 is for attaching the upper part of the front lens 2. The boundary portion 5a with the lower flange 3b is formed thin to provide elasticity.

The front lens 2 is molded into a desired shape using a resin material, and has a waterproof rib 7 surrounding the entire front opening 1a of the lamp body 1 and a circumferential side wall 8 formed protruding from the same body.

The waterproofing rib 7 is formed in an annular shape surrounding the entire circumference of the front opening 1a of the lamp body 1 so as to match the outer shape of the front opening 1a, and its tip surface 7a is in contact with the surface of the mounting flange 3 of the lamp body 1. It is to be formed.

The peripheral side wall 8 is formed at an outer position of the waterproofing rib 7, substantially parallel to the waterproofing rib 7, and protrudes downward from both left and right sides of the front lens 2. That is, this peripheral wall 8 is formed so as to abut and engage with the end faces of the mounting flange 3 of the lamp body 1, particularly the left and right flanges 3c and the lower flange 3b. And this peripheral side wall 8
In this case, an engaging hole 9 and a engaging hole 10 are formed at positions corresponding to the engaging claw 4 and the hooking claw piece 5 protruding from the mounting flange 3 of the lamp body.

The engagement holes 9 are formed in the upper part of the circumferential wall 8 corresponding to the engagement claws 4 protruding from the left and right flanges 3 c of the lamp body 1 , and the engagement holes 10 are formed in the upper part of the lower flange 3 of the lamp body 1 .
An opening is formed in the lower part of the circumferential wall 8 corresponding to the hooking claw piece 5 protruding from b.

When assembling the front lens 2 to the lamp body 1, first, with the upper part of the front lens 2 tilted forward, the lower part of the front lens 2 is brought into contact with the lower part of the lamp body 1. As shown by the two-dot chain line in FIG. 3, insert the hook piece 5 of the lamp body 1 between the waterproof rib 7 of the front lens 2 and the circumferential side wall 8, and hold the upper part of the front lens 2 in the lamp body. One direction (arrow m in the figure)
When the light body 1 is rotated about the hook piece 5 of the lamp body 1 in the direction shown by , the hook piece 5 of the lamp body is inserted into and engaged with the engagement hole 10 of the front lens 2. Next, when the upper part of the front lens 2 is pressed against the lamp body 1, the engaging claw 4 of the lamp body is inserted and fitted into the engaging hole 9 of the front lens 2, and the front lens 2 is integrated with the lamp body 1. .

<Effects of the invention> Since the automotive lamp of the present invention is constructed in this way, the front lens can be assembled to the lamp body with one touch without using any special parts or tools, and is therefore superior to conventional ones. In comparison, the number of parts and assembly man-hours can be reduced, leading to significant cost reductions.

In addition, a waterproofing rib that surrounds the entire front opening of the lamp body is provided protruding from the front lens, and a peripheral side wall is extended outside the waterproofing rib, so there is no need to use sealant or packing material. There is no risk of rainwater entering the lamp chamber between the front lens and the lamp body.

Therefore, the intended purpose can be achieved.
