CONSTITUTION: A device for preventing the discharge of a battery of a vehicle comprises an accessory power supply detecting unit(11), an illumination power supply detecting unit(12), a control unit(13), an alarm(14), and an illumination power supply cut-off unit(15). If a tail light(22b) or a room lamp(22a) is left in the on state when a drier gets off a vehicle, an operating signal is applied to the alarm and the power supply cut-off unit by the control unit. The alarm warns the driver by issuing an alarm. Thereafter, the power supply cut-off unit cuts off the power supply of the lamps.

Description

Apparatus for preventing a battery from discharging in a motor vehicle}

The present invention relates to a device capable of preventing the discharge of the battery by warning the driver when the driver gets off while the light device of the automobile is turned on and cutting off the power of the light device.

A general automobile as shown in FIG. 1 is provided with a lighting device including various lamps, wirings, fuses, switches, and the like for various purposes such as lighting, indicating, signaling, warning, and decoration.

Among such lighting devices, lighting such as an indoor light (1) for illuminating the interior of a vehicle or a tail light (3) installed under the headlight (2) in front of the vehicle body is usually powered directly from a battery to operate regardless of the operation of the engine. Is supplied.

Therefore, when the driver gets off after the vehicle has finished driving, unless the interior light or tail light is turned off due to the driver's carelessness, the accessory light powered from the battery is kept in the lit state until the next time the vehicle runs. As a result, when such accessories are left in the lit state, the battery is completely discharged and the starter cannot be operated. Therefore, the engine cannot be started and the vehicle cannot be operated.

Accordingly, the driver must bear the inconvenience of connecting the battery of another vehicle and the discharged battery by using a jump cable to charge the battery or to replace the battery with a charged battery.

The present invention has been made in view of the above-mentioned, the driver warns the driver when getting off without turning off the lights directly supplied from the battery, such as indoor lights or taillights, and the battery is completely discharged. It is an object of the present invention to provide a battery discharge preventing device for a vehicle that can be prevented.

1 is a perspective view of a typical vehicle.

Figure 2 is a schematic diagram showing a battery discharge preventing device according to an embodiment of the present invention.

An apparatus for preventing battery discharge of a vehicle according to the present invention for achieving the above object includes an accessory power detector for detecting on / off of an accessory power source; An illumination power detection unit for detecting on / off of power of various lights supplied directly from a battery; A control unit for applying an operation signal when the accessory power detection unit is detected to be in an off state from the accessory power detection unit and the lighting power detection unit is in an on state from the lighting power detection unit; An alarm unit for generating an alarm signal to the driver when an operation signal is applied from the controller; And an illumination power cutoff unit which cuts off the illumination power when an operation signal is applied from the controller.

The alarm unit preferably generates an alarm sound through the speaker of the audio device. In addition, the power cutoff unit is preferably operated after a predetermined time elapses after the operation signal is applied from the controller.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

2 illustrates an apparatus for preventing battery discharge of a vehicle according to an exemplary embodiment of the present invention.

As shown, the vehicle battery discharge prevention device according to an embodiment of the present invention, the accessory power detector 11, the illumination power detector 12, the control unit 13, the alarm unit 14 and the illumination power cut-off unit ( 15).

The accessory power detector 11 is for determining whether the driver gets off the vehicle and detects whether the accessory power source 21 is on or off.

The lighting power detector 12 detects whether the lights, such as the indoor light 22a or the taillight 22b, are turned on or off from the lights directly supplied from the battery 23.

The control unit 13 is connected to the accessory power detector 11 and the illumination power detector 12. The controller 13 determines whether the driver gets off with the lights 22a or 22b turned on from the signals input from the accessory power detector 11 and the illumination power detector 12, and the driver turns on the lights. When it is determined to get off, the operation signal is applied to the alarm unit 14 and the lighting power cut-off unit 15.

The alarm unit 14 generates an alarm sound for the driver to recognize through the speaker 24. In this case, the speaker 23 may use a speaker of the audio device, and an alarm sound may also use a voice of a pre-recorded person.

The lighting power cut-off unit 15 illuminates a predetermined time, preferably 5 seconds after the operation signal is applied from the control unit 13 through the relays 25a and 25b connected to the power input terminals of the lights 22a and 22b. The power supplies 22a and 22b are cut off.

When the driver turns the ignition key to the OFF state in order not to turn off the light that is directly supplied from the battery 23 such as the interior light 22a or the tail light 22b, the accessory power supply (ACC) 21 is turned off. It is in the Off state and the lighting power is (On). When the accessory power source 21 detected by the accessory power detector 11 is in an off state and the power source of the lights 22a and 22b detected by the illumination power source detector 12 is in the on state, The driver determines that the driver gets off with the lights turned on and applies the operation signal to the alarm unit 14 and the power cut-off unit 15.

Accordingly, the alarm unit 14 alerts the driver by generating an alarm, and after a predetermined time has elapsed, the power cut-off unit 15 cuts off the power of the lights 22a and 22b.

The device for preventing battery discharge of a vehicle according to the present invention as described above generates an alarm so that the driver can recognize and take action when the driver gets off without turning off the light supplied directly from the battery, such as an indoor light or a tail light. In addition, there is an advantage to prevent the battery from being completely discharged by cutting off the power supply.

In the above, the present invention has been illustrated and described with respect to certain preferred embodiments. However, the present invention is not limited only to the above-described embodiments, and those skilled in the art to which the present invention pertains may vary without departing from the spirit of the technical idea of the present invention described in the claims below. It can be changed.
