Description

[Detailed description of the invention] <<Industrial application>> The present invention relates to vehicle lighting equipment such as signal lights and auxiliary headlights, and in particular surrounds a lamp bulb and converts the light emitted from the lamp bulb into a predetermined colored light. This invention relates to a vehicle lamp equipped with a changeable colored cap.

<<Prior Art>> FIG. 4 shows an example of such a conventional vehicle lamp.

This vehicle lamp 1 is, for example, a turn signal lamp, and includes a housing 3 having an opening 2 on the front side.
A lamp bulb 4 is inserted and held in the rear part of the housing 3, and an amber cap 5 is arranged and fixed to the housing 3 surrounding the lamp bulb 4.
and a lens 6 bonded to the front surface of the housing 3.

The housing 3 is integrally molded with synthetic resin,
At the rear, there is a socket mounting hole 7 and a groove 8 formed around the entire front part of this socket mounting hole 7.
It is equipped with In addition, a groove 9 is provided at the periphery of the opening 2.
is formed.

The lamp bulb 4 is attached to the socket 1 attached to the rear socket attachment hole 7 of the housing 3.
0 within the housing 3.

The amber cap 5 has a substantially cylindrical shape with a front end that completely surrounds the entire lamp bulb 4 held in the housing 3, and a rear end 5a that covers the lamp bulb 4 and is inserted into the socket mounting hole 7 of the housing 3. It is inserted into the peripheral groove 8 and bonded with an adhesive 11.

The lens 6 is a white transparent lens, and is provided with a leg portion 12 that continues toward the rear along its entire periphery. Agent 13
are connected via.

FIG. 5 shows another example of such a conventional vehicle lamp. This differs from the conventional example described above only in the mounting structure of the amber cap.

The entire front periphery of the socket mounting hole 15 of the housing 14 includes a recessed step 17 into which the amber cap 16 can be fitted, and a boss having a mounting hole protruding forward at the bottom of the recessed step 17. 18.

Furthermore, a fixing piece 19 is integrally formed at a predetermined position on the outer circumferential portion of the amber cap 16, protruding outwardly and having a screw insertion hole in the front-rear direction. The amber cap 16 has a rear end portion 1.
6a is fitted into the recessed step 17 of the housing 14, the fixing piece 19 is brought into contact with the front surface of the boss part 18 of the housing 14 so that each hole communicates with the other, and the screw 20 is inserted through the screw insertion hole of the fixing piece 19. is attached by screwing into the attachment hole of the boss portion 18.

<<Problem to be solved by the invention>> However, in such conventional vehicle lamps, the colored cap is fixed to the housing using a separate member, that is, an adhesive in the former conventional example, and an adhesive in the latter conventional example. In this case, screws are used for fixing, which has the problem of poor workability and increased assembly man-hours.

Furthermore, in the former prior art fixing structure for the colored caps, the interior of the colored caps becomes high in temperature due to the heat generated when the lamp bulb is turned on, and there is a risk that the adhesive force of the adhesive may decrease and the colored caps may fall off.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a vehicle lamp in which a colored cap can be easily and reliably attached to a housing.

<Means for Solving the Problems> In order to solve the above-mentioned problems, a vehicle lamp according to the present invention is a vehicle lamp in which a colored cap surrounding the lamp bulb is disposed on a lamp body holding a lamp bulb. The lamp body is characterized in that a groove is provided in the periphery of the colored cap installation position, and a protrusion that is press-fitted into the groove is integrally provided on the outer periphery of the colored cap.

<<Operation>> The colored cap surrounding the lamp bulb is fixed to the lamp body by having a protrusion integrally provided on its outer circumference press-fitted into a groove provided in the lamp body.

<<Embodiment>> FIG. 1 shows an embodiment of a vehicle lamp according to the present invention.

This vehicle lamp 21 is, for example, a turn signal lamp, and includes a housing 23 which is a lamp body having an opening 22 on the front, a lamp bulb 24 held at the rear of the housing 23, and a housing surrounding the lamp bulb 24. Amber cap 25 arranged and fixed to 23 and housing 2
The lens 26 is cemented to the front surface of the lens 3.

The housing 23 is integrally molded from synthetic resin, and has a socket mounting hole 27 at the rear, a recessed step 28 formed around the entire front part, and upper and lower positions around the recessed step 28. Each of the grooves 29 is provided with a T-shaped groove 29 as shown in FIG. Further, a groove 3 is provided at the peripheral edge of the opening 22.
0 is formed.

The lamp bulb 24 is held within the housing 23 via a socket 31 that is mounted in a rear socket mounting hole 27 of the housing 23.

The amber cap 25 is integrally molded with synthetic resin, and has a substantially cylindrical shape with a closed front part that surrounds the entire lamp bulb 24 inserted and held within the housing 23, and has a symmetrical shape at the rear end of its outer periphery. Projections 32 are formed at two locations that project outwardly and are press-fitted into respective grooves 29 provided at the upper and lower portions of the periphery of the recessed step 28 of the housing 23 . As shown in detail in FIG. 2, these protrusions 32 are continuous to the rear end of the outer periphery of the amber cap 25 in a T-shape that can be fitted into each groove 29 of the housing 23 in the outward direction, and the horizontal portion 33
A bulging bead 34 is formed at the front of the plane part and the front part of both side parts. Then, attach the rear end of the outer periphery of the amber cap 25 to the housing 23.
The protrusions 32 are fitted into the grooves 28 at the top and bottom of the groove 28, as shown in FIG. That is, the amber cap 25 is T
Each bead 34 formed on each letter-shaped protrusion 32 is pressed against and fixed to the inner wall surface of each T-shaped groove 29 of the housing 23 .

The lens 26 is a white transparent lens, and is provided with leg portions 35 that extend rearward around its entire periphery.The leg portions 35 are inserted into the groove portion 30 at the periphery of the opening 22 of the housing 23, and are inserted into the hot melt. They are bonded via a sealant 36 such as:

In this way, this vehicle lamp 21 has an amber cap 25 fitted into the recessed step 28 of the housing 23, and each protrusion 3 integrally formed on the outer circumference of the amber cap 25.
Since the amber cap 25 is press-fitted and fixed into each groove 29 provided at the top and bottom of the periphery of the recessed step 28, the amber cap 25 can be easily and reliably assembled to the housing 23. That is, the amber cap 25 can be assembled to the housing 23 with one touch. Also,
According to this fixing structure, it is possible to prevent the amber cap 25 from wobbling in the vertical and lateral directions and to securely fix the amber cap 25. Also,
In addition to eliminating the need for separate fixing members such as adhesives and screws and associated fixing jigs as in the past,
The amber cap 25 can be prevented from falling off without being affected by heat generated when the lamp bulb 24 is turned on.

<<Effects of the invention>> As described above, according to the vehicle lamp of the present invention,
A groove is provided in the periphery of the colored cap installation position of the lamp body, and a protrusion that is press-fitted into the groove is integrally provided on the outer periphery of the colored cap, and the protrusion is press-fitted into the groove to insert the colored cap into the groove. Since it is fixed, the colored cap can be easily and reliably assembled to the lamp body. In addition, this fixing structure eliminates the need for separate fixing members such as adhesives and screws as in the past, and prevents the colored cap from falling off without being affected by the heat generated when the lamp bulb is lit. .
