Description

The present invention relates to a structure for attaching a vehicle lamp such as a high mount stop lamp to a vehicle body.

Conventionally, when installing a high-mount stop lamp at the rear of a vehicle body, a printed substrate (3) having a light source (light emitting diode 4) is supported on a housing (cover body 13) as disclosed in the following patent documents. It is customary to connect the housing to the lens (lens body 5), fix them to the decorative cover (case body 21), and then attach the decorative cover to the vehicle body (inner surface of the rear windshield 23). It was.

When such a mounting structure is adopted, a housing is interposed between the light source and the lens. Then, the deviation of the position of the substrate with respect to the housing is added to the deviation of the position of the housing with respect to the lens, and the deviation between the optical axis of the light emitted from the light source and the lens, in other words, the error may become large. .. Even if such a deviation occurs, in order to ensure that the required amount of light is output through the lens in the desired direction, a high-brightness, high-performance illumination light source must be used. However, this led to an increase in cost.

An embodiment of the present invention will be described with reference to the drawings. The vehicle lighting equipment of the present embodiment is a type of tail lamp (tail lamp) installed at the rear of the vehicle body, particularly a high mount stop lamp 2 independently installed at a high position in the center in the width direction of the vehicle body. As is well known, the high mount stop lamp 2 is a third brake lamp (brake light), which lights up in conjunction with the operation of the brake pedal of the driver of the vehicle, and the vehicle is currently decelerating with respect to the following vehicle and its surroundings. It is intended to clearly indicate that the vehicle is in the middle or stopped.

FIG. 1 is a side sectional view showing a mounting structure of the high mount stop lamp 2 of the present embodiment. In FIG. 1, the rear upper part of the vehicle body is enlarged and shown, the right side of the figure is the front side and the passenger compartment side of the vehicle, the left side is the rear side of the vehicle and the outside of the passenger compartment, and the upper and lower parts are the upper side of the vehicle. It is the lower side.

The high mount stop lamp 2 is attached to the upper part of the back door 1 of the vehicle, for example. The upper part of the back door 1 is provided with an outer panel 11 located on the outside of the vehicle interior and an inner panel 12 located on the vehicle interior side. The outer panel 11 and the inner panel 12 may be made of metal or resin, respectively.

The outer panel 11 is a frame body having an opening that serves as a window. A window glass 13 is fixed to the opening via a sealing member (not shown) so as to close the opening. The inner panel 12 is joined to the outer panel 11 so as to face the outer panel 11.

The high mount stop lamp 2 is supported by the inner panel 12 of the back door 1. The high mount stop lamp 2 is exposed through the window glass 13 at the central portion near the upper edge of the window of the back door 1 when viewed from the rear of the vehicle. When the high mount stop lamp 2 is turned on, the light 3 emitted from the light source 21 is emitted toward the outside of the vehicle interior through the window glass 13.

The high-mount stop lamp 2 of the present embodiment has a substrate 22 that supports the light source 21 and is provided with an electric circuit connected to the light source 21, and a lens 23 that is directly fastened to the substrate 22 and allows light 3 emitted by the light source 21 to pass through. And a decorative cover 24 to which the lens 23 is fixed and attached to the inner panel 12 of the back door 1 while supporting the lens 23 and the substrate 22.

The substrate 22 is provided with a light emitting diode 21 as a light source on the rear surface side. However, the light source is not limited to the light emitting diode 21, and other types of lamps may be used as the light source. The substrate 22 is provided with a penetrating insertion hole 221 through which a screw 25 for fastening the substrate 22 to the lens 23 can be inserted. On the other hand, the lens 23 is provided with a boss 231 projecting forward toward the substrate 22, and a female screw hole is cut in the inner circumference of the boss 231. The boss 231 functions as a nut for screwing the screw 25. When fastening the substrate 22 and the lens 23, the rear surface side of the substrate 22 is abutted against the boss 231 while aligning the insertion holes 221 of the substrate 22 with the female screw holes of the boss 231 and inserted from the front side of the substrate 22. A screw 25 is inserted into the hole 221 and the male screw of the shaft portion of the screw 25 is screwed into the female screw hole of the boss 231.

The decorative cover 24 is, for example, a resin-made member having an opaque light-shielding property, and plays a role of suppressing the invasion of the light 3 emitted by the light emitting diode into the vehicle interior side. The decorative cover 24 includes a bottom wall 241 forming the bottom surface of the high mount stop lamp 2 and a front wall 242 that is connected to the front edge of the bottom wall 241 and rises diagonally forward and upward. The lens 23 is fixed to the decorative cover 24 by joining the lower end portion thereof to the upper surface of the bottom wall 241 of the decorative cover 24. The upper end portion of the front wall 242 is inserted into a concave groove 121 formed in advance in the inner panel 12 of the back door 1 and fixed to the inner panel 12. By engaging the upper end portion of the front wall 242 of the decorative cover 24 with the concave groove 121 of the inner panel 12, it is possible to preferably prevent the light 3 emitted from the light emitting diode 21 from leaking to the vehicle interior side.

According to the present embodiment, since the substrate 22 supporting the light source 21 and the lens 23 are directly fastened, the light source 21 emits light without any other member such as a housing intervening between the two. The displacement between the optical axis of light and the lens 23 can be reduced. Therefore, it is guaranteed that the required amount of light 3 is output through the lens 23 in a desired direction, and the need for using the high-brightness, high-performance light source 21 is eliminated, which contributes to cost reduction. Can be done.

In addition, the weight of the high mount stop lamp 2 is reduced by eliminating a member such as a housing interposed between the substrate 22 and the lens 23. Of course, the cost of the housing is also reduced.

Further, no housing is provided on the front side of the substrate 22 (the back side of the substrate 22 in the sense of the opposite side of the light source 21), and a gap having a predetermined size is provided between the front side of the substrate 22 and the front wall 242 of the decorative cover 24. By forming and opening the front side of the substrate 22, heat dissipation efficiency is improved, and the life of the high mount stop lamp 2 can be expected to be extended.

The present invention is not limited to the embodiments described in detail above. For example, the application target of the present invention is not limited to the high mount stop lamp 2. It is also conceivable to apply the present invention to other aspects of vehicle lighting, such as taillights such as brake lamps and license lamps.

In addition, the specific configuration of each part can be variously modified without departing from the spirit of the present invention.

The present invention can be applied to a high mount stop lamp or the like mounted on a vehicle.
