Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicular lamp such as a rear combination lamp, and more particularly to a mounting structure of an inner lens in a vehicular lamp provided with an outer lens and an inner lens.

[0002]

[Prior Art]

 FIG. 4 shows an example of a conventional mounting structure for the inner lens 91 in this type of vehicle lighting device 90. An opening 92a is provided at an appropriate position on the side surface of the housing 92, and the inner lens 91 The outer edge is provided with a hook portion 91a corresponding to the opening portion 92a, and the hook portion 91a is inserted into the opening portion 92a for attachment. After the inner lens 91 is attached, The outer lens 93 is attached so as to cover the inner lens 91 using a seal groove 92b provided at the tip of the housing 92.

However, in this type of vehicular lamp 90, the number of cases where a colorless and transparent outer lens 93 is adopted recently has increased due to a request from an automobile design side, and in this case, the inner lens 91 of the inner lens 91 is increased. The hook portion 91a is viewed as a black spot through the outer lens 93, and there is a problem in that the vehicle lamp 90 alone or the entire vehicle is very unnatural in terms of design. The solution had become an issue.

[Means for Solving the Problems]

 As a concrete means for solving the above-mentioned conventional problems, the present invention provides an opening on a side surface of a housing of a vehicle lamp, and inserts a hook provided on an outer edge of an inner lens into the opening. In the inner lens mounting structure for a vehicle lamp to be mounted, a step portion is provided on a side surface of the housing, the step portion expanding toward an insertion direction for mounting the inner lens, and the opening portion is provided at an appropriate position in contact with the step portion, On the outer edge of the inner lens, a leg portion that is substantially flush with the inner diameter of the stepped portion is provided on the insertion direction side, and a hook portion corresponding to the opening is provided on the outer side surface of the leg portion. A problem is solved by providing an inner lens mounting structure for a vehicular lamp, wherein a shielding plate that covers at least the leg portion of the inner lens is provided inside. Than it is.

【Example】

 Next, the present invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 in FIG. 1 denotes a vehicular lamp. An opening 21a is provided on a side surface 21 of a housing 2 of the vehicular lamp 1, and a hook portion 31a provided on the inner lens 3 is provided in the opening 21a. It is similar to the conventional example in that it is inserted and attached.

However, according to the present invention, as shown in FIG. 2, a side surface 21 of the housing 2 is provided with a step portion 21b which is widened toward the insertion direction for mounting the inner lens 3, and the opening portion 21a is provided with the step portion 21b. By using a so-called so-called cut-out structure as a mold structure for forming the step portion 21b, the step portion 21b is provided at an appropriate position in contact with the step portion 21b.

Further, the inner lens 3 is provided at its outer edge with a frame-shaped leg portion 31 projecting toward the insertion direction side when it is attached to the housing 2, and the leg portion 31 is provided. The inner diameter of the hook portion 31a is substantially flush with the inner diameter of the step portion 21b provided in the housing 2, and the hook portion 31a corresponds to the position where the opening portion 21a is provided on the outer surface of the leg portion 31. Are provided (see FIG. 1).

In addition, in the present invention, the shielding plate 4 is attached to the inner surface of the housing 2 so as to cover at least the leg portion 31 of the inner lens 3 in the attached state. In this type of vehicular lamp 1, since the reflecting mirror 5 is usually provided inside the housing 2, the shielding plate 4 is provided with the edge portion of the reflecting mirror 5 on the rear surface 32 of the inner lens 3. It is preferable to form an integral body by extending it until it touches.

A seal groove 22 is provided at the tip of the housing 2, and the outer lens 6 is attached by using the seal groove 22, but this portion has been described in the conventional example. Since the configuration is exactly the same as, the detailed description is omitted here.

Next, the operation and effect of the present invention having the above-described configuration will be described. By providing the shield plate 4 that reaches the back surface 32 of the inner lens 3 and covers the legs, the housing 2 and the inner member 3 are provided. When this portion is viewed through the outer lens 6 with the lens 3 attached, the leg portion 31 of the inner lens 3 and the inner diameter of the housing 2 are substantially flush with each other, so that the appearance is improved. The leg portion 31 is completely covered with the shielding plate 4 without causing unsightly appearance, which means that the hook portion 31a provided on the outer side surface of the leg portion 31 is also covered, and The hook portion 31a becomes invisible and no black spots are formed.

FIG. 3 shows another embodiment of the present invention. The previous embodiment is an example in which the reflecting mirror 5 is provided in the housing 2 and thus the shielding plate 4 is formed integrally with the reflecting mirror 5. As described above, this embodiment corresponds to the case where the housing 2 itself is formed in the shape of a reflecting mirror and aluminum vapor deposition is performed, and a separate reflecting mirror is not used. In this case, the shielding plate 7 is the inner member. For example, the inner surface of the leg portion 31 of the lens 3 is formed by performing coating or taping with the above-described aluminum vapor deposition and color matching. Since the operation and effect of this embodiment are completely the same as those of the previous embodiment, detailed description thereof is omitted here.

[0012]

[Effect of the device]

 As described above, according to the present invention, the step portion is provided on the side surface of the housing and the opening portion is provided at the step portion, and the outer edge of the inner lens is provided with the leg portion which is substantially flush with the inner diameter of the step portion. By providing a hook portion on the outer surface of the leg portion and providing a shield plate that covers at least the leg portion of the inner lens at the inner portion of the housing, the inner lens mounting structure for a vehicle lamp is provided. The hook part can be shielded without causing unsightly appearance, which prevents the occurrence of black spots in the vehicle lamp due to the peristaltic hook, and gives a sense of quality to this type of vehicle lamp. It is extremely effective in improving
