BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luggage door which is supported at a front end of a luggage room at a rear portion of a vehicle body so as to be openable upward, and a rear spoiler is mounted at a rear end of the luggage door. The present invention relates to a vehicle stop display device provided on a vehicle to which a stop lamp is attached.

[0002]

2. Description of the Related Art This type of stop display device used in the event of an emergency stop of a vehicle is separately prepared such as installing a triangular sign on the road or installing a rotary stop indicator on the roof. Instead, according to Japanese Patent Application Laid-Open No. Hei 8-301008, the present applicant attaches a triangular light-transmitting member to the back surface of a luggage door and sets a light-guiding portion protruding from a light-transmitting portion at the bottom of the door. At the front end, a lens that forms a light introduction surface that faces the high-mount stop lamp placed on the package tray when the luggage door is opened and allows the light to enter therethrough, and reflects the light emitted through the light guide to the rear of the vehicle. We proposed a car stop display device in which the cut part is formed of a translucent body.

[0003]

Thus, when the luggage door is opened, the triangular translucent body is turned on by the light emission of the high mount stop lamp placed on the package tray. A structural problem remains in that a light-transmitting body that emits light in the entire region is required.

[0004] In view of the above, the present invention provides a vehicle stop display device that can reliably notify an emergency stop with a simpler configuration using a high-mount stop lamp provided on a luggage door. The purpose is to do.

[0005]

In order to achieve this object, according to the present invention, a front end of a luggage door is supported at a front end of a luggage room at a rear portion of a vehicle body so as to be openable upward. In addition, a rear spoiler is mounted on the rear end of the upper surface of the luggage door, and in a stop display device provided on a vehicle having a high-mount stop lamp mounted on the rear surface of the luggage door bent downward from the upper surface of the luggage door, At least in the area above the high mount stop lamp on the rear surface of the rear spoiler protruding upward and backward from the upper end, a reflective surface shaped to face rearward with the luggage door open is formed,
The upper part of the outer lens of the high-mount stop lamp is formed as a Fresnel lens that partially emits the light toward the reflecting surface so that the light emission of the high-mount stop lamp is reflected backward with the luggage door open, The high-mount stop lamp is driven by a blinking drive circuit in response to a detection signal of a switch that detects the opening of the luggage door.

When the switch detects the opening of the luggage door, the high mount stop lamp is driven by the blinking drive circuit. The flashing emission of the high mount stop lamp illuminates the reflecting surface through the Fresnel lens. The flickering light is emitted rearward so that it can be visually recognized from the vehicle behind by the reflection surface facing rearward by opening the luggage door.

According to the first aspect, instead of forming the upper part of the outer lens as a Fresnel lens, according to the second aspect, the light is reflected backward inside the upper part of the outer lens of the high mount stop lamp with the luggage door open. As described above, a dedicated lamp that causes colored light emission to be directed toward the reflecting surface is incorporated, and the dedicated lamp can be driven by a blinking drive circuit in response to a detection signal of a switch that detects opening of the luggage door. . In order to perform the blinking display only at the time of the actual emergency stop, the blinking drive circuit is started by the lighting operation of the hazard lamp switch in a state where the switch detects the opening of the luggage door.

The upper surface 2a of the rear spoiler protrudes rearward from the rear surface 1b of the luggage door while slightly rising rearward.

The rear spoiler rear surface 2b projects obliquely upward and rearward from the upper end of the luggage door rear surface 1b and reaches the rear end of the rear spoiler upper surface 2a, so that the luggage door 1 has a concave surface facing rearward with a maximum open state of about 45 °. It is formed in a shape. The rear surface of the luggage door exhibits light reflection characteristics with a reflective paint mixed with glass beads or the like, a film having a high reflectivity, plating, or a smooth white paint film.

As shown in FIGS. 1 and 2, the upper part of the outer lens 10 of the high mount stop lamp 5 has a red Fresnel that deflects the light emitted from the bulb 5a toward the rear surface 2b of the rear spoiler and slightly diffuses the light. Lens 1
1 is formed. On the other hand, rear spoiler rear surface 2b
The central region functions as a reflection surface 12 for the light transmitted by the Fresnel lens 11, and has a concave shape so that the light incident from the Fresnel lens 11 can be visually recognized from a vehicle behind the vehicle in a fully open state. To reflect.

At the rear end of the luggage room floor,
A switch 7 is provided for turning on a courtesy lamp that illuminates the interior of the luggage room when the luggage door 1 is opened. FIG. 4 shows a drive circuit for operating the bulb 5a as a stop display device by using this switch. In response to a detection signal of the switch 7, the drive input to the bulb 5a is changed to a normal stop lamp drive circuit. And a switching circuit 17 for supplying from a hazard lamp blinking drive circuit 16.

The operation of the thus configured stop display device is as follows. When the luggage door 1 is opened during an emergency stop, the switch 7 turns on the courtesy lamp and activates the switching circuit 17. Accordingly, when the hazard lamp switch is operated, a blinking drive input is supplied from the blinking drive circuit 16 to the bulb 5a instead of the DC-form stop lamp drive input, and the high-mount stop lamp 5 emits a continuous red light during normal braking. Flashes red instead of lit.

Accordingly, red colored light is emitted from the Fresnel lens 11 to the central area of the rear surface 2b of the rear spoiler rotated to a high position, and blinking light is emitted backward from the reflective surface 12 in a wider area than the outer lens 10. Then, the emergency stop state is notified to the following vehicle.

FIG. 5 shows another embodiment of the present invention. The outer lens 10 of the high-mount stop lamp 5 is shown in FIG.
Is partitioned by a partition 18 and the reflecting surface 12
A red LED 19 is housed inside the lens extension 13 as a dedicated lamp so as to be able to face the lens. As a result, diffused light is emitted toward the reflection surface 12 through the lens extension portion 13. The LED 19 is directly driven via the switch 7 by the hazard lamp blinking drive circuit 16 of FIG. The lens extension 13 may have a Fresnel lens shape that diffuses the red light of the LED 19 in the horizontal direction.

Further, as another drive circuit, an LED 19
The bulb 5a may be configured to be driven by the blinking drive circuit 16 in response to only the detection signal of the switch 7 irrespective of the operation of the hazard lamp switch. The blinking drive circuit may be configured independently of the hazard lamp, or the switch may be dedicated to the courtesy lamp.
Further, a Fresnel-shaped reflecting surface can be formed only in the central region on the rear surface of the spoiler.
