The present invention relates to a power distribution control device for minimizing vehicle battery discharge. More specifically, the load of the continuous power connected directly to the battery side is grouped into a load group requiring previous information maintenance and a load group requiring no previous information maintenance. The present invention relates to a power distribution control device capable of minimizing discharge by reducing the dark current caused by the continuous power supply to a load group that does not need to maintain previous information when the vehicle is not used for a long time by pinging.

1 is a view showing a conventional power distribution structure, the OFF, ACC, ON, START contacts are formed in the ignition switch rotary 1 is connected to the battery 3 and the contact according to the position of the ignition key.

Insert the ignition key into the ignition switch rotary (1) in the OFF position, rotate it, and start the engine without starting the engine, that is, the ACC position where an electric device, ie a radio, a cigarette lighter, etc. can be used, and all electric lights while checking various warning lights before starting. Each function is performed by moving to the ON position where the device can be used and the START position for driving the starting motor, and a load is connected to each contact point.

That is, depending on which contact of the ignition switch rotary (1) is connected to the vehicle load can be divided into ACC load (4), ON load (5), START load (6), in particular, regardless of the position of the ignition key A load that is always powered (hereinafter referred to as an "always power load") 7 is directly connected to the battery 3.

If the driver turns the ignition key to the START position and the engine is started, the ignition key remains in place and at the same time the ignition key is automatically reversed to the ON position. Operate.

In case of removing the ignition key, rotate the ignition key to the ACC position, rotate it in the pushed state, and move it to the OFF position to remove it.

However, when the vehicle is left for a long time, the battery 3 is discharged, and thus, the starting motor cannot be driven. Therefore, it is often impossible to start the vehicle and to start the vehicle using the power of another vehicle.

This discharge of the battery 3 always occurs due to the characteristics of the battery 3, but its speed is closely related to the constant power load 7 connected to the vehicle.

In other words, the load (4,5) connected to the ACC position or the ON position is irrelevant to the discharge of the vehicle because the contact point is not connected and the power of the battery 3 is not supplied until the start key is rotated to reach the position. The load 7 causes a dark current in the state that the vehicle is turned off, which acts as the main cause of the vehicle discharge.

On the other hand, in order to solve this problem, a technique for cutting off the power or preventing the discharge of the battery is disclosed in Korean Patent Publication Nos. 2004-3436, 2004-48025, 2006-4769, 2006-19330, etc. Prior art is to turn off the power of the load of the load, especially during the constant power supply, especially when the risk of high discharge or detecting the battery voltage is lowered completely turn off the power stage.

The present invention has been devised to minimize vehicle battery discharge, unlike the prior art described above, and uses the vehicle for a long time by grouping the load of the constant power into a load group requiring previous information maintenance and a load group requiring no previous information maintenance. If not, the purpose of the present invention is to provide a power distribution control device capable of minimizing discharge by reducing the dark current caused by the constant power by interrupting the supply of the constant power to the load group that does not need previous information maintenance.

Power distribution control device for minimizing vehicle battery discharge according to an embodiment of the present invention for achieving the above object, the battery power to the load depending on which contact point of the ignition switch rotary to the ignition switch to distinguish the load of the vehicle In the device for supplying,

The normal power load is grouped into two groups, but the normal power is used before the operation of the load group (B1 load) and simply the start-up key operation. It is characterized in that it is grouped into a load group (B2 load) irrelevant to information retention, and is provided with a constant power distribution switch that cuts off the supply of the continuous power to the B2 load when the vehicle is not used for a long time.

As described in the related art, in order to minimize vehicle discharge, it is necessary to minimize dark current caused by loads using the constant power in view of the power distribution system.

For this reason, if the driver does not start the vehicle for a long time, the risk of discharge can be minimized if the continuous power supply is cut off to the constant power load. Should be considered.

For example, in the case of a digital clock of a vehicle, if the power is disconnected and then reconnected, all values such as time are reset, which causes inconvenience of resetting the time, and the data of the ECU is also reset.

On the other hand, in case of load such as power seat, it uses normal power (because the seat is adjusted before starting key operation), but even if the power supply is cut off for a long time, it is not a problem next time.

Therefore, it is necessary to reclassify the load using the constant power.

That is, it is necessary to distinguish between a load that causes inconvenience when the supply of the constant power is cut off for a long time, and a load that does not cause any problem when the supply is supplied again.

From this point of view, the present invention groups the continuous power into two groups based on the above criteria at the point where the battery is divided into the respective loads of the constant power, and then the driver may constantly apply the power to the load group corresponding to the latter. OFF can greatly reduce vehicle discharge.

Hereinafter, the configuration and operation of the embodiments of the present invention will be described with reference to the accompanying drawings, and like reference numerals refer to like elements.

2 is a diagram illustrating a grouping structure of a constant power load for implementing the present invention.

As shown, the constant power load 7 is grouped into two groups, the criteria of which is whether or not it is a problem when the constant power is turned off, that is, the load group (digital clock, ECU, etc.) to maintain previous information. , `` B1 Load '') (7a) and the load group irrelevant to maintaining the previous information using the constant power supply since it must be used before the operation of the ignition key (hereinafter referred to as `` B2 Load '') It is divided into (7b).

3A and 3B are diagrams before and after operation for explaining the concept of the present invention using FIG.

The B1 load 7a and the B2 load 7b may be selected by the driver to select 'maintain power connection between B1 load and B2 load' or 'maintain power connection only for B1 load'.

To this end, the regular power distribution switch 10 is divided into a fixed end 11 and a moving end 12 to branch the fixed end 11 into the B1 fixed end 11a and the B2 fixed end 11b, and the mobile end ( 12) B1 fixed end 11a forms a constant contact with B1 moving end 12a for supplying power to B1 load 7a, and B2 fixed end 11b selectively forms a contact with B2 load 7b. It is formed by separating the B2 moving end (12b) for supplying power.

That is, the B1 moving end 12a always maintains contact with the B1 fixed end 11a even when moved by the driver's operating means, and supplies the constant power of the battery 3 to the B1 load 7a, but the B2 moving end When 12b is moved by the operation of the driver's operating means, the contact point with the B2 fixed end 12a is dropped, and the B2 load 7b cannot supply the constant power of the battery 3 to the B2 load 7b (see Fig. 3B).

In this case, the default value is 'maintain power connection between B1 and B2 load' as shown in FIG. 3A. However, when the vehicle is not used for a long time (for example, when traveling for a long time) such that vehicle discharge is concerned, As described above, only the B1 load is maintained at all times by the driver's operating means, so that the constant power is supplied only to the B1 load 7a.

As a result, the vehicle discharge due to the B2 load 7b is prevented at the source to minimize the discharge by reducing the dark current caused by the constant power.

Figures 4a and 4b is a view before and after the operation with the operating means in the grouping structure of FIG.

As shown in Figure 4a, the operating means 20 is provided in the constant power distribution switch 10 of FIG.

The actuating means 20 includes a case 21 enclosing the external power distribution switch so as to protect the regular power distribution switch, a B1 moving end 12a forming a contact point in the middle of the B1 fixing end 11a, and An insulating bar 22 for coupling the B2 moving end 12b that forms a contact at an end of the B2 fixed end 11b to be spaced a predetermined distance apart, and one end of which is fixed to the case 21 so that the other end is insulated from the insulating bar 22. The return spring 23 is connected to the middle portion of the) and the operating rod 24 is connected to the insulating bar 22 on the opposite side of the return spring 23 protruding out of the case 21.

In addition, a locking hole 24a is formed in the operating rod 24, and a locking hole 25 is installed at the lower portion of the operating rod 24 to restrict the movement of the operating rod 24 by being caught by the locking hole 24a. .

One side of the locking hole 25 is coupled to rotate to the hinge shaft 26, the other end of the hinge shaft 26 is supported by the fixing body 28, the other end of the locking hole 25 A torsion spring 27 is inserted to push the latch 25 toward the operating rod 24, and a locking protrusion 29 protrudes from the upper side of the opposite side on which the hinge shaft 26 is formed.

In the above configuration, when the vehicle is not used for a long time and the driver pulls the operation rod 24 to the right as shown in FIG. 4B, the return bar 23 fixed to the case 21 expands and the insulation bar 22 is expanded. Resiliently moving to the right, thereby moving the B1 moving end 12a and B2 moving end 12b coupled by the insulating bar 22 to the right.

When the operating rod 24 is moved and the locking hole 24a of the operating rod 24 is moved to the place where the locking protrusion 29 of the locking hole 25 is located, the other side of the locking hole 25 is hinge shaft 26. The locking protrusion 29 is inserted into and caught by the locking hole 24a while being raised by the torsion spring 27 about the center.

At this time, the B1 fixed end 11a and the B1 moving end 12a form a contact point at the end thereof, and the contact point of the B2 fixed end 11b and the B2 moving end 12b is separated, so that the constant power is supplied only to the B1 load 7a. It is supplied, and it is in a state where a constant power is not supplied to B2 load 7b.

FIG. 5 is a view in which the return means is provided in FIG. 4B. FIG.

If the vehicle is not used for a long time and the vehicle is frequently used, the constant power should be supplied to both the B1 load 7a and the B2 load 7b. The return means 30 to be returned to the position of FIG. 4A, which is the position, should be provided in the constant power distribution switch 10 in which the actuation means 20 is implemented.

The return means 30 is located inside the ignition switch rotary 1 and when the starter key 2 is rotated from the ON position to the start position, the return means 30 rotates together with the starter key 2 to connect the contact point of the START load 6. And a contact switch 31 which is made and restored to the ON position, and is connected to the contact switch 31 and is pulled when the contact switch 31 is rotated, and a lower part of the other side of the locking hole 25. When one end is coupled and the other end is connected to the pulling line 32 and the pulling line is pulled, the other side of the locking hole 25 is rotated downward to stop the locking protrusion 29 at the locking hole 24a of the operating rod 24. A tension bar (34) which allows the pulling spring (33) to be pulled out to release the latch, and the pulling spring (33) can be pulled at an appropriate tension when the pulling wire (32) connected thereto is pulled as the contact switch (31) rotates. )

In the state where the constant power is supplied to the B1 load 7a and the constant power is not supplied to the B2 load 7b, the driver inserts the ignition key 2 into the ignition switch rotary 1 and rotates to start the ignition. The contact switch 31 inside the switch rotary 1 rotates with the starter key 2 to pull the pull string 32 connected to the contact switch 31.

Therefore, the other side of the locking hole 25 pivots around the hinge shaft 26 by the pulling spring 32 connected to the pulling line 31 to rotate downward to release the locking protrusion 29, thereby returning the inflated return. The actuating rod 24 and the moving end 12 are returned to their original positions by the spring 23, and a contact is formed again between the moving end 12 and the fixed end 11, so that the default state of 'B1 load and B2' is achieved. Maintain power connection at constant load.

And when the start with the start key (2) in the default state it can be seen that the latch 25 is rotated by the return means 30, but irrelevant to the contact formation of the constant power distribution switch 10.
