Description

  The present invention relates to a vehicular rearward confirmation device disposed in a vehicle such as a one-box vehicle or a hatchback vehicle.

It is known that in a vehicle rear confirmation device, a rear confirmation camera is attached to substantially the center of a rear bumper at the rear of the vehicle (Patent Document 1).
JP-A-9-150670

  However, in such a vehicle rear confirmation device, since the rear confirmation camera is attached to the rear bumper, muddy water adheres to the camera lens when water smoke rises during running in rainy weather, or the like. Even if muddy water does not adhere, if the tires of your vehicle cause water spray near the ground to obstruct the camera lens's field of view, the camera's field of view is obstructed and the rear view is confirmed. There was a problem that would become difficult.

  The present invention has been made in view of the above problems, and an object of the present invention is to maintain the reliability of backward confirmation by a camera.

Therefore, in the present invention, in a vehicle rearward confirmation device including a camera for confirming the rear of the vehicle, the camera is disposed in a high-mount stop lamp provided at a position above the rear bumper.
Further, a pair of the high mount stop lamps may be provided on both sides in the vehicle width direction at the rear part of the vehicle, and preferably, the camera may be provided at substantially the center of the high mount stop lamp.

  According to the present invention, even if the rear bumper is contaminated with water smoke, the camera is disposed in a high-mount stop lamp provided at a position above the rear bumper, and the water rising above the rear bumper The airflow that flows along the vehicle will flow to the rear of the vehicle, so it will not reach the high-mount stop lamp, and the camera lens placed in the high-mount stop lamp will not get dirty, so you can reliably check the rear. There is an effect.

Further, since a pair of high mount stop lamps are provided on both sides in the vehicle width direction at the rear of the vehicle, each camera can take an image of a different predetermined range, and there is an effect that the rear can be confirmed over a wide range.
Further, if the camera is provided at substantially the center of the high-mount stop lamp, the appearance of the high-mount stop lamp (or the rear part of the vehicle) can be improved by, for example, symmetrically arranging brake lamps on both sides thereof.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 3, a vehicle rearward confirmation device 1 according to the present invention is used for rearward confirmation in a high-mount stop lamp 3 provided above a rear bumper 12 of a vehicle (here, a one-box vehicle) 2. The camera 4 is provided.
Here, the “high-mount stop lamp” is disposed at a position above the rear bumper 12 at the rear part of the vehicle and near the front (vehicle interior) or rear (outside the vehicle compartment) of the rear window 6 and relates to the brake lamp. This means that the red light is irradiated to the rear of the vehicle. Accordingly, in the present invention, the rear confirmation camera 4 is disposed above the rear bumper 12 even when muddy water adheres to the rear bumper 12 when water smoke rises during rainy weather or the like. It is possible to prevent muddy water from adhering to the lens of the camera 4. And even if the water rises above the rear bumper 12, the water flows to the rear of the vehicle by the airflow flowing along the vehicle body, so it does not reach the high mount stop lamp 3 (rear confirmation camera 4), The backward confirmation by the backward confirmation camera 4 can be reliably performed.

  A pair of high-mount stop lamps 3 are provided on both sides in the vehicle width direction at the rear of the vehicle. Since the maximum possible shooting range of one rear confirmation camera 4 is about 30 ° in the vertical direction and the horizontal direction, the overall shooting range can be expanded by providing a pair of high-mount stop lamps 3 on both sides in the vehicle width direction. It is possible to take a picture of the rear of the vehicle as a blind spot of the driver (see FIG. 2).

  The high-mount stop lamp 3 is fixed to the inner side (vehicle interior side) of the back door 5 via a fastener such as a bolt. Thus, the rear confirmation camera 4 can confirm the rear of the vehicle through the rear window 6. Even if muddy water adheres to the rear window 6 and the field of view of the rear confirmation camera 4 is temporarily blocked, the rear window 6 can be cleaned again by removing dirt with a wiper (not shown). The field of view of the camera 4 can be ensured.

Moreover, the high mount stop lamp 3 is comprised like FIG. 4 or FIG. 5 from a viewpoint of the improvement of the beauty | look in a vehicle rear part, and the efficiency of arrangement | positioning.
In FIG. 4, when the rear confirmation camera 4 is installed in the high-mount stop lamp 3 of the type including the red LED 10, the high-mount stop lamp 3 of the type including the red bulb (bulb) 11 is illustrated in FIG. 5. The case where the camera 4 for back confirmation is installed is each shown. Since the same effect is obtained even when the red bulb 11 is used, the description will be given only for the red LED 10.

The exterior of the high-mount stop lamp 3 is attached to a main body cover 3a having a substantially rectangular parallelepiped box shape with a vehicle rear side surface (a surface facing the rear window 6 in FIG. 2) opened, and an opening of the cover 3a. The lamp cover 3b is included.
A rear confirmation camera 4 and a red LED 10 are disposed in the main body cover 3a (in the high-mount stop lamp 3).

A CCD camera is used as the rear confirmation camera 4 and is provided at the approximate center in the main body cover 3a. Three red LEDs 10 are symmetrically arranged on both sides of the rear confirmation camera 4.
The red LED 10 is configured to light up in association with the lighting of the taillight (brake lamp) 9 by a brake signal.

A lamp cover 3b is attached to the opening of the main body cover 3a so as to cover the rear confirmation camera 4 and the red LED 10.
Here, a through hole 3c corresponding to the diameter of the lens 4a of the rear confirmation camera 4 is formed in the approximate center of the lamp cover 3b. After the lamp cover 3b is attached to the opening of the main body cover 3a, The confirmation camera 4 can confirm the rear of the vehicle.

  As described above, the rear confirmation camera 4 is configured integrally with the high-mount stop lamp 3, so that the high-mount stop trump 3 and the rear confirmation camera 4 are provided separately from the case where the high-mount stop trump 3 and the rear confirmation camera 4 are provided separately. Save time and effort. And since the camera 4 for back confirmation is provided in the approximate center of the high mount stop lamp 3, the red LED 10 of the both sides of the camera 4 can be regularly arranged, and the aesthetics of the high mount stop lamp 3 (rear part of the vehicle) can be improved. it can.

Referring again to FIGS. 1 to 3, a monitor (display) 7 for displaying an image taken by the rear confirmation camera 4 is provided in the vehicle interior. The rear confirmation camera 4 and the monitor 7 are connected by a cable 8 that transmits a signal (video data behind the vehicle) from the rear confirmation camera 4 to the monitor 7 (FIG. 1).
The monitor 7 is disposed on the dashboard or the like so that the driver can easily visually recognize the video photographed by the rear confirmation camera 4. As the monitor 7, for example, a small liquid crystal display device such as a vehicle-mounted television is used.

  For example, when the shift lever is set to the reverse position, the rear confirmation camera 4 and the monitor 7 are switched to ON. As a result, when the tail lamp (back lamp) 9 is lit and the rear of the vehicle is illuminated, the rear confirmation camera 4 facilitates the rear confirmation, and the vehicle 2 can be moved backward safely.
