BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described, but are not limited thereto without departing from the gist of the present invention.
[0020]
1A and 1B show an embodiment of the present invention, in which FIG. 1A is a perspective view of a rear seat portion of an automobile, and FIG. 1B is an enlarged front view in a dotted line.
[0021]
The opening / closing device for opening the door from the outside has a knob 14 for releasing the lock and a recess 15 for facilitating the grip of the knob 14 as shown in the figure. Then, in order to prevent an unexpected accident due to a hook, the vehicle door 12 is configured to bulge out from the outer surface of the vehicle door 12 at a gentle inclination.
[0022]
The light source unit 11 is housed in a housing 11 a configured to be at the same height as the knob 14. As the light source, a light bulb, an LED, or the like is used, but there is no particular limitation. Hereinafter, an LED will be described as a light source.
[0023]
Needless to say, the housing 11a is required to have a necessary portion having translucency. The illustrated example is a housing that can transmit light downward and rearward.
It is preferable to arrange an LED that projects downward and an LED that projects backward within one housing 11a. The LED projecting downward is for illuminating the foot when getting on and off, and the LED projecting backward is for informing the rear vehicle or a pedestrian approaching from behind that the door is open. Of course, the purpose of the door open display can be achieved by either downward projection or rearward projection.
It can also be projected to the side. In this case, for example, it is effective for visual recognition when the door lock is released by the remote switch, and it is possible to easily confirm the position of the own vehicle at night.
It can also be projected forward. In this case, it is a sign that calls attention to a car or a pedestrian approaching from the front.
[0024]
In rear projection, one LED is sufficient because the light source can be directly viewed. On the other hand, the foot illumination is preferably bright because it reflects light from a light source, and it is preferable to arrange two or more LEDs. The brightness increases as the number of LEDs increases, but it is most preferable that the number of LEDs increases to 3 from the viewpoint of the size of the housing 11a and power consumption.
[0025]
The vehicle door opening operation display device of the present invention may be mounted on any one of the doors, particularly on the driver's seat side which is most frequently opened and closed. However, it is more effective to attach to all doors so that they are all lit when the door is opened.
[0026]
A control mechanism for mounting the vehicle door opening operation display device of the present invention on all doors and turning on all the doors when any door is opened will be described below.
[0027]
2A and 2B show an example of a vehicle door opening operation display device control mechanism of the present invention, wherein FIG. 2A is a block diagram, and FIG. 2B is a time chart showing the operation.
[0028]
In this example, four LEDs are illustrated as the light source unit 21. One is for rearward projection and three are for downward projection.
[0029]
The power supply 24 is a battery mounted on a vehicle and is supplied with 12 V power. The power supply flows to a ground (body ground) 25 via a power supply 24-a control unit 23-a light source (LED) 21-a control unit 23 for controlling a light source driving current-a door courtesy switch 22. When the door courtesy switch 22 is open (OFF), power supply is also cut off.
[0030]
The door courtesy switch 22 includes a switch 22a that is closed when the driver's seat door is unlocked, a switch 22b that is closed when the driver's seat door is opened, and a switch 22c that is closed when any door other than the driver's seat is opened. As doors other than the driver's seat, four passenger doors, rear left and right doors, and a back door are exemplified. Switches other than the driver's seat are each provided with a switch that is closed by a door opening operation. Circuits including these are connected in parallel by P and further include a switch 22b that is closed by opening the driver's door. The circuit is adapted to enter the control unit 23 by D.
[0031]
The circuit from the switch 22a, which is closed by the release of the driver's door lock, enters the timer circuit of the control unit 23 via L, and after the driver's door lock is released, a certain time (for example, 10 seconds, this time is, for example, about 3 to After that, the LED is turned off while fading out for about 3 seconds, for example.
[0032]
Next, the operation will be described with reference to a time chart (FIG. 2B).
[0033]
First, when the driver's door lock is released, the switch 22a is closed and the LED is turned on (1 in the figure). At this time, the timer circuit operates to turn off the LED after a certain period of time. Even if the driver's seat door lock is opened, the door may not be actually opened, or the vehicle may be driven with the driver's seat door lock open, so that useless lighting is prevented. The release of the driver's door lock includes keyless entry.
[0034]
When the driver's seat and other doors are opened, at least one of the switches 22b and 22c is closed. At this time, the LEDs are turned on when the switches are closed (2 in the figure), and are turned off when opened (3 in the figure).
[0035]
