Abstract

In a battery discharge preventing circuit for a car comprising an oblivion detector, its output and a bypass circuit of the present invention, an oblivion detector detects that parking and tail lights are left turned on when a driver forgets to turn them off and carelessly turns off the ignition switch or pulls out the ignition key and leaves the car. When the oblivion detector detects that parking and tail lights are left turned on, said detector output opens the parking and tail light circuit and automatically turns off parking and tail lights. Thereby, the present invention prevents a car battery from being discharged.

Description

DESCRIPTION
Title of Invention
Battery Discharge Preventing Circuit For A Car
Technical Field
This invention relates to a battery discharge preventing circuit to be applied to a parking and tail light circuit for a car or the like.
Background Art
In a parking and tail light circuit of a car, parking and tail lights are controlled by a light switch. If a light switch is turned to a Park position, parking and tail lights will be turned on. If the light switch is turned to a OFF position, said lights will be turned off. In case a driver forgets to turn off said lights and maintains a light switch to the PARK position, said lights will be remained turned on.
FIG. 3 is an example of a circuit diagram showing a prior art of such a parking and tail light circuit. A light switch 6 is the switch to control parking and tail lights. When a driver turns the light switch 6 to the PARK position, a parking and tail light relay 7 will be energized. Then, said relay contact 8 will be closed and parking and tail lights will be turned on. If a driver forgets to turn off said lights when he pulls out the ignition key and leaves from the car, said lights will be remained turned on and a car battery will be discharged slowly. Thus, there has been a problem that, if a driver forgets to turn the light switch 6 to OFF position and leaves parking and tail lights turned on all day long, the battery will be totally discharged and he won't start the car without helping other battery. Disclosure of the Invention
An object of the present invention is to provide a battery discharge preventing circuit for a car, which will open a parking and tail light circuit and automatically turn off parking and tail lights when a driver completely forgets to turn off said lights.
Another object of the invention is to provide a bypass switch, which can bypass a battery discharge preventing circuit whenever it is necessary.
Another object of the invention is to provide a bypass lamp, which displays to a driver that a battery discharge preventing circuit is bypassed.
A battery discharge preventing circuit according to the present invention comprises a parking and tail light turning -off oblivion detecting means detecting that a driver forgets to turn off parking and tail lights and leaves said lights turned on, a parking and tail light turning - off means opening a parking and tail light circuit and automatically turning off parking and tail lights when a parking and tail light turning-off oblivion detecting means detects said lights left turned on, and a parking and tail light turning-off bypassing means bypassing the battery discharge preventing circuit.
The other features and advantages of the present invention will become apparent enough with the following explanations.
Brief Description of the Drawings
FIG. 1 is a circuit diagram showing a battery discharge preventing circuit embodying the present invention. FIG. 2 is a diagram showing an example of a conventional ignition switch FIG. 3 is a circuit diagram showing an example of prior art of a parking and tail light circuit.
Best Mode of Carrying out the Invention
FIG. 1 is a circuit diagram showing a battery discharge preventing circuit embodying the present invention.
An oblivion detector 5 is installed between an ignition key interlock contact 4 and the PARK contact of a light switch 6. A parking and tail light automatic turning-off section 2, which is composed of an oblivion detector output 9 and a bypass circuit 3, is connected at anywhere of a parking and tail light control section 1 in order to automatically turn off parking and tail lights when the oblivion detector 5 detects that a driver completely forgets to turn off parking and tail lights and leaves said lights turned on
The ignition key interlock contact 4 is closed when the ignition switcMFIG. 2) turns off to the LOCK position or when the ignition key is pulled out, and said interlock contact 4 is opened when the ignition switcMFIG. 2) is turned to any position of ACC, ON, or START(designated when the ignition switch is turned -on condition hereinafter). The Park position of the light switch 6 is to turn on parking and tail lights.
The oblivion detector 5 as shown in the FIG. 1 is energized when both the ignition key interlock contact 4 and the PARK contact of the light switch 6 are closed at the same time; the ignition key interlock contact 4 is closed when the ignition switcMFIG. 2) is not on the tumed-on condition, that is, when the ignition switcMFIG. 2) is turned off to LOCK position or when the ignition key is pulled out. Said detector 5 is de-energized when either the ignition switch is on the turned-on condition or the PARK contact of the light switch 6 is opened by turning the light switch 6 to OFF position. The oblivion detector output 9 is opened when the oblivion detector 5 is energized and said detector output 9 is closed when the oblivion detector 5 is de-energized.
When the ignition switch is on the turned-on condition, the oblivion detector 5 becomes de-energized and said detector output 9 is closed. At this moment, if the light switch 6 is turned to the Park position, a parking and tail light relay 7 will be energized and said relay contact 8 is closed. Therefore, parking and tail lights will be turned on. If a driver carelessly turns off the ignition switcMFIG. 2) or pulls out the ignition key without turning off the light switch 6 while parking and tail lights are turned on, the oblivion detector 5 will be energized due to the closure of the ignition key interlock contact 4 since the PARK contact of the light switch 6 has already been closed. Once the oblivion detector 5 becomes energized, said detector output 9 is opened and the parking and tail light circuit will be opened. Therefore, parking and tail lights will be automatically turned off and the battery discharge will be prevented.
A bypass circuit 3 is to enable a driver to bypass the battery discharge preventing circuit and turn on parking and tail lights when the ignition switch is not on the turned-on condition. When a bypass switch 10 is depressed, the oblivion detector output 9 is bypassed and a bypass lamp 13 is lit. When the oblivion detector output 9 is bypassed, parking and tail lights can be controlled by the light switch 6 as shown in the FIG. 3 of prior art of a parking and tail light circuit. The bypass lamp 11 will remind a driver of the battery discharge preventing circuit bypassed so that he can restore the bypass switch without forgetting.
In the present invention, it is apparent that different working modes in a wide range can be formed on the bases of the present invention without deviating from the spirit and scope of the invention. The present invention is not restricted by its specific working modes except being limited by the appended claims.
