DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear combination lamp structure for an automobile having a housing for accommodating a lamp and an inner cap fitted into an opening of the housing.

[0002]

2. Description of the Related Art There is a conventional rear combination lamp structure for an automobile constructed as follows.

That is, a rear combination lamp provided at the rear end of the vehicle body in a side cross-sectional view of the rear portion of the vehicle body,
A housing having an opening supported by a rear wall of the vehicle body and opening rearward at a rear end thereof, a valve disposed inside the housing, a lens for closing the opening, and the valve fitted in the opening; And a resin inner cap that covers the rear side of the inner cap, extends substantially horizontally in a flat manner, and integrally extends forward and downward from the upper and lower portions of the inner cap, and these extended ends are connected to the housing. An upper and lower pair of connecting plates are provided, and the inner cap is connected to the housing by these connecting plates.

In addition, the inner cap has a cap body constituting an intermediate portion in the vertical direction of the inner cap, and upper and lower plates extending integrally from the upper and lower ends of the cap body toward the front, respectively. And a pair of upper and lower outward flanges integrally extending from the extending end portions of the upper and lower plates, respectively, in a direction away from each other in the vertical direction.

In the above construction, as shown by a two-dot chain line in FIG. 1, each of the connecting plates is integrally extended forward from a front surface of a vertically intermediate portion of each of the outward flanges. I have.

[0006]

By the way, in the above-mentioned prior art, the connecting plate is integrally extended from the front surface of the middle part in the vertical direction of the outward flange as described above. When the rear combination lamp is viewed from the rear of the vehicle body, the base (FIG. 1)
A, B) can easily be seen through the outward flange and the lens, which is not preferable because it causes the appearance of the rear combination lamp to deteriorate.

Second, when the inner cap is resin-molded by injection molding or the like, sink marks tend to be formed on the rear surface of the outward flange corresponding to the base of the connecting plate. This is also undesirable because it can be seen through the flange and the lens, which also reduces the appearance of the rear combination lamp.

Conventionally, in a plan view of a vehicle body, the width dimension of the connecting plate remains large at its base in each part in the front-rear direction. A part of the illuminating light going downward is apt to be blocked in a wide range by the connecting plate, which also causes the appearance of the rear combination lamp to deteriorate at the time of lighting, and also causes the inside of the rear combination lamp to be degraded. As a result, the heat resistance becomes insufficient, and the heat radiation becomes insufficient, so that the rear combination lamp tends to become hot.

Therefore, it is conceivable to reduce the width dimension of the connecting plate. However, if this is simply done, the strength of the connecting plate may be insufficient, and the connecting strength of the inner cap to the housing may be insufficient. Occurs.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and improves the appearance of the rear combination lamp when viewed from the rear of the vehicle body and increases the heat-resistant capacity inside the rear combination lamp. It is another object of the present invention to prevent the rear combination lamp from being heated to a high temperature and to firmly connect the inner cap to the housing even in such a case.

In a plan view of the vehicle body 1 (FIG. 3), each of the connecting plates 14 and 15 is tapered forward.

For this reason, the width dimension of each of the connecting plates 14 and 15 is set, for example, at each portion in the front-rear direction.
The area of each of the connecting plates 14 and 15 can be reduced as compared with the case where the large size in 9 is left.

Therefore, it is possible to prevent a part of the irradiation light from the bulb 10 from being blocked by the connecting plates 14 and 15 in a wide range, thereby improving the appearance when the lamp 5 is turned on. Since the heat-resistant capacity inside the lamp 5 is increased, heat is sufficiently released, and the temperature of the lamp 5 is prevented from becoming high.

In the above case, the connecting plates 14 and 15 for connecting the inner cap 12 to the housing 8 have a greater stress on the bases 28 and 29 side than on the extended end side due to the load from the housing 8. Likely to happen,
Each of the connecting plates 14 and 15 has a tapered shape facing forward, and the width of each of the bases 28 and 29 can be increased. Therefore, an increase in stress on the bases 28 and 29 is suppressed. .

The rear surface of the cap body 20, the outer surfaces of the upper and lower plates 21 and 22, and the rear surfaces of the outward flanges 24 and 25 in the inner cap 12 are substantially centered in the width direction of the vehicle body 1, respectively. A relief 31 having a uniform width and extending in the vertical direction is formed. The relief 31 is formed by a large number of groove shapes extending parallel to each other in the up-down direction. The relief 31 scatters the light emitted from the bulb 10 when it is transmitted. The appearance of the lamp 5 is improved.

In the above configuration, the bases 28 and 29 of the connecting plates 14 and 15 and the relief 31 are located at substantially the same position in the width direction of the vehicle body 1 and the base 2
The width dimensions of 8, 29 and the relief 31 are substantially the same.

For this reason, when the lamp 5 is viewed from the rear of the vehicle body 1, the bases 28, 29 of the connecting plates 14, 15 are provided.
Is easily seen through the lens 11 is also more reliably prevented by the relief 31.

Therefore, the base 2 of each of the connecting plates 14 and 15
Since the lamps 8 and 29 are not easily seen, the appearance of the lamp 5 is improved.

The extending end of the upper connecting plate 14 is connected to the housing 8 by the locking member 16 of the locking member 16 and the fastener 17, and the lower end of the lower connecting member 14 is connected to the housing 8 by the fastener 17. The extended end of the connecting plate 14 is connected to the housing 8.

For this reason, when the lamp 5 is viewed from the rear of the vehicle body 1, the lower connecting plate 15 of the extended ends of the connecting plates 14 and 15 which is less visible from the rear of the vehicle body 1. Since the extended end is connected to the housing 8 by the fastener 17, the fastener 17 can be easily seen through the inner cap 12 and the lens 11 in combination with the presence of the relief 31. Is prevented.

Therefore, the appearance of the lamp 5 is improved because the fastener 17 is not easily seen.

Although the above description is based on the illustrated example, the extending ends of the connecting plates 14 and 15 may be connected to the housing 8 by a locking member 16 together.
7 may be used. In addition, each of the connecting plates 1
4 and 15 may be triangular in plan view of the vehicle body 1, or only one of them may be tapered.

The inner cap is provided with a pair of lower and upper connecting plates that extend integrally from the lower part toward the front and are connected to the housing, respectively.

The inner cap includes a cap body constituting a middle part of the inner cap in the vertical direction, an upper and lower plate integrally extending forward from upper and lower ends of the cap body, respectively. In a rear combination lamp structure of an automobile having a pair of upper and lower outward flanges integrally extending in a direction away from each other in the vertical direction from each of the extending ends of the upper and lower plates,

The extending ends of the upper and lower plates and the bases of the upper and lower connecting plates respectively corresponding thereto are located at substantially the same position in the vertical direction.

For this reason, first, when the lamp is viewed from the rear of the vehicle body, the fact that the base of each of the connecting plates can be easily seen through the outward flange and the lens means that the upper and lower plates can be easily seen. Is prevented by

Therefore, the appearance of the lamp is improved because the base of each connecting plate is not easily seen.

Second, when the inner cap is resin-molded by injection molding or the like, the upper and lower plates are opposed to each other in the front-rear direction at the base of the connecting plate. The occurrence of sink marks on the rear surface of the outward flange is prevented.

Therefore, the appearance of the lamp is further improved by the absence of sink marks on the rear surface of the outward flange.

According to a second aspect of the present invention, the connecting plate has a tapered shape facing forward in a plan view of the vehicle body.

For this reason, the area of the connecting plate can be reduced as compared with the case where the width of the connecting plate is kept large at its base in, for example, the front-rear direction.

Therefore, it is possible to prevent a part of the irradiation light from the bulb from being blocked by the connecting plate in a wide range, thereby improving the appearance at the time of lighting of the lamp and improving the inside of the lamp. Since the heat-resistant capacity is increased, heat is sufficiently released, and the temperature of the lamp is prevented from becoming high.

In the above case, the connecting plate for connecting the inner cap to the housing tends to generate a larger stress on the base side than on the extended end side due to the load from the housing. It is tapered toward the front and its width at the base side can be increased, so that an increase in the stress at the base side is suppressed.

Therefore, as described above, even when the appearance of the lamp is improved and the temperature is prevented from becoming high, the connection of the inner cap to the housing is firmly performed by the connection material.
