[0001] The present invention relates to a fan register controller, and more particularly, to a fan register controller that allows a protection device to be coupled to one end of a fan resistor controller, .

Generally, a cooling device including a fan (for example, an axial fan) is installed in the vehicle for cooling the heat exchanger, and the fan is rotated by the fan motor to cool the heat exchanger.

In this case, the fan motor is selected and driven in two or more stages of high speed and low speed. In order to adjust the speed of the fan motor, a resistor Resistor controller (or a fan register controller) is installed.

The register controller includes a first connector (not shown) connected to the fan motor and a second connector (not shown) connected to a power source of the vehicle. A low speed operation circuit is configured by connecting the register controller and the fan motor . And the voltage supplied to the fan motor is controlled to be low by the low speed operation circuit, whereby the fan motor is driven at a high speed to a low speed. Therefore, a resistor (R) constituting an electric resistor for adjusting the intensity of the current is installed in the register controller.

At this time, the fan motor of the vehicle usually has no problem, but there may be a situation where the fan motor is restrained due to an accident that the vehicle is subjected to a strong impact such as a collision, a collision or the like due to a peripheral circuit or a component failure. As described above, when the fan motor is restrained and the fan can not rotate, a current (overcurrent) exceeding a certain level flows to the fan motor, resulting in a safety accident such as fire and electric shock.

Therefore, in order to prevent a problem caused when the fan motor is restrained, a conventional resistor controller includes a separate fuse mounted at a low speed (LO), as shown in FIG. 1, And when the fan motor is restrained in the high-speed stage (HI), it is generally configured to detect the overcurrent in the fuse box (not shown) of the vehicle and to interrupt the current.

However, as a result of the analysis of the vehicle fire accident, there is a problem that the fuse operation time of the vehicle is actually large and the probability of occurrence of fire in the fan motor is still high.

The background art of the present invention is disclosed in Korean Registered Patent No. 10-1335698 (registered on November 26, 2013, Register for a motor controller).

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a fan register controller, which is coupled to one end of a fan resistor controller to allow a protection device to operate before a fuse operates, It has its purpose.

In the present invention, the protection device may be integrally formed inside the fan resistor controller or detachably attached to the outside of the fan resistor controller.

In the present invention, the protection device is characterized in that, when the vehicle is powered off, the blocking state is restored.

In the present invention, the protection device is connected to one end of the internal circuit of the fan register controller, and the one end is connected to at least one of the high speed terminal (HI), the low speed terminal (LO), and the ground terminal Or more.

In the present invention, the fan register controller may further include a connector-shaped detachable portion formed in a housing of the fan resistor controller to couple the protection device to the fan resistor controller.

In the present invention, the protection device includes: a current sensing unit that senses an amount of current flowing according to an operation mode of the fan motor; And a circuit blocking / returning unit for shutting off the flow of current when the current sensed by the current sensing unit is equal to or greater than a preset current amount, and returning the flow of the blocked current when the current sensed through the current sensing unit is less than a preset current amount. And a control unit.

In the present invention, the current sensing unit and the circuit breaker / return unit may be integrally formed.

In the present invention, the current sensing unit and the circuit breaker / return unit may include at least one material whose physical characteristics change according to a current flow.

The protective device 100 or 100 'may be configured such that when the fan motor is restrained during a high speed or low speed operation of the fan motor and a current (overcurrent) do.

In addition, when the constraint of the fan motor is released and a current less than a predetermined level flows, the protective devices 100 and 100 'can automatically return to flow the current again. Alternatively, the protection devices 100 and 100 'may be reset and automatically return to the normal state when the vehicle power is off (i.e., ignition off).

The protection devices 100 and 100 'may be installed only in the high-speed stage HI as shown in FIG. 2 (a), or may be installed in the high-speed stage HI and the low- LO, or may be installed only at the ground terminal (GND) as shown in FIG. 2 (c).

When the protection device 100 or 100 'is installed only in the high speed stage HI, the fan motor is protected in the case where the high speed fan motor is constrained, and the protection device 100 or 100' ) And the low speed stage (LO), and when the protection device (100, 100 ') is installed only at the ground terminal (GND), the fan motor is protected when the fan motor in high speed or low speed operation is arrested .

As described above, the protective devices 100 and 100 'according to the present embodiment operate before the fuse operates to interrupt the current flowing in the fan motor, and automatically return when the current cutoff condition is released, . As a result, there is an effect of preventing the occurrence of safety accidents such as fire, an effect of operating the fan motor without replacing the fuse, and an effect of preventing destruction of the fan motor and the resistor.

The fan register controller according to the present embodiment can be realized by integrally embodying the protective devices 100 and 100 'in the inside or by connecting one end (eg, high speed end HI, low speed end LO, (Or coupling) of the protection devices 100 and 100 'can be realized by forming a connector-shaped removable portion 130 (see FIG. 4) in the housing, which can be connected to the ground (GND) .

If the protective devices 100 and 100 'are installed at the high speed end HI and the low speed end LO respectively as shown in FIG. 2B, the attaching / detaching unit 130 (see FIG. 4) Two may be formed.

The current sensing unit 110 senses a current amount (or a level) flowing according to an operation mode of the fan motor (for example, high speed mode, low speed mode, etc.).

The circuit blocking / returning unit 120 cuts off the current flow when the current sensed through the current sensing unit 110 is equal to or greater than a predetermined current amount (or level). Also, the circuit blocking / returning unit 120 returns the flow of the blocked current when the current sensed through the current sensing unit 110 is less than a predetermined current amount (or level).

The current sensing unit 110 and the circuit breaker / return unit 120 may be integrally formed.

The current sensing unit 110 and the circuit breaker / return unit 120 may include at least one material whose physical characteristics change according to the current flow. That is, the circuit breaker / return unit 120 switches or reconnects the circuit by switching the contact (not shown) through which the current changes due to the change of physical characteristics.

FIG. 4 is an exemplary view illustrating a configuration in which a protector is coupled to a fan register controller according to an embodiment of the present invention. Referring to FIG.

As described above, the fan register controller according to the present embodiment can be realized by integrally embodying the protective devices 100 and 100 'in the inside, or at one end (e.g., high speed stage HI, low speed stage LO (Ground terminal (GND)), as shown in Fig.

In this case, when the protective devices 100 and 100 'are integrally mounted in the fan register controller, they can be implemented using a printed circuit board. When the protective devices 100 and 100' are detachably mountable, A connector-shaped detachable attachment portion 130 is formed in the housing of the controller so that the protective devices 100 and 100 'can be detached (or coupled). The protective devices 100 and 100 'may include a housing having a connector shape corresponding to the removable portion 130 formed in the fan resistor and having a rectangular plate shape in a direction of being detached and attached to the detachable portion 130 of the fan resistor. A plurality of terminals are formed so as to protrude from one side of the housing and protrude from one side of the housing, the plurality of plate-like terminals are formed such that relatively narrow faces are opposed to each other, When the fan register controller is detached (or coupled) to the detachable unit 130 of the fan resistor controller, the width of one side of the fan register controller is gradually reduced toward the protruding portion of the plurality of terminals, .

As described above, according to the present embodiment, the protective devices 100 and 100 'integrally implemented or detached inside the fan resistor controller operate before the fuse operates to cut off the current flowing to the fan motor, When the constraint of the fan motor is released, the fan motor is returned to operate the fan motor. This prevents the occurrence of safety accidents such as fire, the effect of operating the fan motor without replacing the fuse when the current interruption condition is released, and the destruction of the fan motor and the resistor due to the quick operation before the fuse operates .
