If you park for a long time without turning off, it is common to see that the starter, which requires a heavy load when the battery is discharged and starts again, is unable to perform due to its inability to start.

Therefore, FIG. 1 has a problem in that battery discharge cannot be prevented when parking for a long time without turning off the system (emergency light, radio, indoor light, tail light) operated by the battery's constant power.

That is, the power supplied from the battery 1 via the slow blow fuse 2 is always supplied even when the start switch 3 is turned off (emergency light, radio, indoor light, tail light, etc.). In this state, power is continuously supplied.

Therefore, there is a problem in that the battery is discharged by a long time power supply, there is a problem that the start motor is unable to start due to the battery discharge when the driver wants to start due to the battery discharge.

The present invention has been made to solve the problems described above, the vehicle and heavy equipment constant power cut-off that controls the power supply through the timer relay for the components of the vehicle and heavy equipment that is always powered even in the start switch off state The purpose is to provide a system.

That is, according to the present invention, when a long time is parked while forgetting to switch off each of the vehicle and heavy equipment components operated by the battery constant power, the timer is turned off if the continuous state of the start switch continues for a predetermined time or more. Its purpose is to provide a vehicle and heavy equipment constant power interruption system that checks this and cuts off the circuits of components that are operated by battery constant power.

In order to achieve the above object, the present invention provides a power system for a vehicle and heavy equipment, comprising: a start switch for determining whether power is supplied to each component of the vehicle and heavy equipment according to a user's request; A timer relay for checking a signal generated when the start switch is not in an off state and cutting off transmission of supply power when the signal does not occur for a predetermined time; And a switching relay for performing or interrupting the supply of the battery constant power to the component operated by the battery constant power of the vehicle and the heavy equipment according to whether the power is supplied through the timer relay.

The present invention is a circuit that applies a timer and discharge cut-off relay that can block battery discharge due to malfunction because the circuit that receives battery constant power is not cut off even when the start switch is turned off after parking the vehicle. This system is applicable to.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a configuration diagram of an embodiment of a vehicle and heavy equipment constant power cut-off system according to the present invention.

The vehicle and heavy equipment constant power cut-off system according to the present invention comprises a battery (1), a slow blow fuse (2), a start switch (3), a timer relay (4) and a switching relay (5).

In the system according to the present invention, the timer relay 4 drives the switching relay 5 to shut off the battery continuous power supply circuit.

When the start switch 3 is moved to the on position, the timer relay 4 receives the signal of the ACC terminal of the start switch 3 and keeps the contact in the on state so that the switching relay ( 5) Since the vehicle and heavy equipment components (emergency lights, radios, indoor lights, taillights, etc.) operated by the battery are always in normal operating condition.

When the start switch is turned off and the signal of the AC terminal of the start switch 3 is not transmitted to the timer relay 4 continuously for 30 minutes, the contact point of the timer relay 4 drops and the switching relay The switching relay 5 was not operated because the coil of (5) could not be driven, thereby causing the battery and heavy equipment components (emergency lights, radios, indoor lights, taillights, etc.) operated by the battery to be constantly operated and malfunctioned. Even if parked for a long time in the state, it is possible to block the battery discharge in advance.

That is, the power supplied from the battery 1 is transferred to the corresponding component via the slow blow fuse 2, the start switch 3 is corresponding to the state selected by the user in the power delivery to these components Command to supply power to the component.

However, in the present invention, since the start switch 3 is approached when the power is not cut off to the circuit which receives the constant power even when the start switch 3 is turned off by the user, the start switch 3 is turned off. In ACC, the signal of the ACC stage, which is not generated, is used as a discrimination criterion.

The timer relay 4 is checking the signal generated from the ACC stage of the start switch 3, and if the signal continues to occur, the timer relay 4 is connected to the power delivered through the slow blow fuse 2. The timer relay 4 releases the power supply state to the switching relay 5 when the supply state to the switching relay 5 is maintained, and the signal at the ACC stage does not occur for 30 minutes. Here, 30 minutes as an example, the power off time may be changed.

The switching relay 5 drives the coil based on the power delivered through the timer relay 4 to maintain the power supply from the slow blow fuse 2 to the circuit consuming the battery constant power, and the timer relay 4 When the power supply that is transmitted through the power supply is interrupted, the driving of the coil is stopped and the power supply to the circuit that consumes battery power is cut off.

The present invention as described above, by using a timer at the time of the start switch (Off) automatically switches the operation of the switching relay after a certain time, the operation of the timer by the AC (ACC) signal at the start switch (On) Command and supply and cut off the circuit power operated by battery constant power through the switching relay.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

The present invention as described above, there is an effect that can be cut off the power supply to the circuit through the timer and the discharge cut-off relay for the circuit that receives the battery constant power even in the start switch-off state of the vehicle and heavy equipment.

In addition, the present invention, there is an effect that can prevent the discharge of the battery due to the malfunction of the system that is operated by the battery always power when the vehicle and heavy equipment parking for a long time.
