Description

[0001] MODULE TYPE PROTECTING APPARATUS FOR FAN RESISTOR CONTROLLER [0002]

[0001] The present invention relates to a fan register controller, and more particularly, to a fan register controller, which is equipped with a modular protection device coupled to one end of a fan resistor controller, Register 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 normally has no problem, but there may be a situation where the fan motor is confined 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.

Also, once the fuse is disconnected once it is turned off, that is, the fuse is used again after the fuse is replaced.

Therefore, in the conventional case, once the fuse is blown, the fan motor can not be driven until the fuse is connected again, which leads to inconvenience in use. In addition, since the fuse of the conventional register controller uses a separately implemented fuse, the material cost is increased, and a noise filter or the like has to be used to fix the fuse.

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-mentioned problems, and it is an object of the present invention to provide a fan resistor controller in which a modular protection device is coupled to one end of a fan resistor controller, And to provide a fan register controller.

A fan register controller according to one aspect of the present invention controls a current applied to a fan motor of a vehicle to adjust a speed of the fan resistor. A pattern wiring formed on the printed circuit board so as to be connected to at least one or more current wiring terminals of the fan resistor controller; And a thermal fuse formed on the thermal fuse.

According to the present invention, in the modular protection device, the thermal fuse is connected to the current sensing resistors, one end of each of which is connected to the plurality of current wiring terminals and the other end of which is connected to a current sensing resistor having a different resistance value, And is cut according to the temperature at which heat is generated when the current flowing through the current sensing resistor is equal to or higher than the allowable current.

In the present invention, the modular 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 modular protection device is connected to one end of the internal circuit of the fan register controller, and the one end is connected to the high speed end (HI), the low speed end (LO) And at least any one of them.

According to the present invention, the modular protection device further includes a case surrounding the printed circuit board on which the thermal fuse and the pattern wiring are printed, and the case is connected to an internal printed circuit And is formed to be hermetically sealed to protect the substrate, and the connection terminal is formed to be drawn out from the case.

In the present invention, the fan resistor controller is characterized in that a connector-shaped detachable attachment portion is formed in the housing of the fan resistor controller to couple the protection device to the fan resistor controller.

A modular protection device is coupled to one end of the fan resistor controller so that the modular protection device is activated before the fuse is operated to prevent the fan motor from being turned on by cutting off the current.

FIG. 2 is an exemplary diagram showing a schematic configuration of a modular protection device coupled to a fan register controller according to an embodiment of the present invention; FIG.
FIG. 3 is an exemplary view for explaining a configuration in which a modular protection device is coupled to a fan register controller according to an embodiment of the present invention; FIG.

Hereinafter, an embodiment of a fan register controller according to the present invention will be described with reference to the accompanying drawings.

In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

FIG. 2 is an exemplary diagram showing a schematic configuration of a modular protection device coupled to a fan register controller according to an embodiment of the present invention. FIG.

2, the fan register controller according to the present embodiment includes a modular protection device 100 at one end (e.g., high-speed stage HI, low-speed stage LO, .

The modular protection device 100 interrupts the flow of current when the fan motor is restrained during a high speed or low speed operation of the fan motor and a current (overcurrent) of a predetermined level or higher flows .

The modular protection device 100 also includes a thermal fuse 120 formed on the substrate and a current sensing resistor 130 connected to one end of the thermal fuse 120.

One end of the thermal fuse 120 is connected to one end of the fan resistor controller (for example, high-speed terminal HI, low-speed terminal LO, and ground terminal GND) And the other end thereof is connected to the current sensing resistor 130. The current sensing resistor 130 is connected to the wiring 110 formed in a copper foil pattern.

Therefore, when the restraining current flows in the current sensing resistor 130 and the temperature rises, the thermal fuse 120 is cut off, thereby blocking the current flowing in the fan motor.

Normally, since the fuse has a normalized allowable current, it is not easy to use a fuse corresponding exactly to the restraining current of the fan motor, so that a fuse having a slight margin is used. Therefore, in practice, considerable variation occurs in the fuse operating time of the vehicle.

However, since the thermal fuse 120 formed in the modular protection device 100 according to the present embodiment is formed to be fixed on the substrate, it is advantageous in that it is very stable from the vibration of the vehicle.

As described above, the modular protection device 100 according to the present embodiment operates before the fuse of the fan resistor controller (or the fuse in the fuse box) operates to interrupt the current flowing in the fan motor.

Accordingly, it is possible to prevent the occurrence of a safety accident such as a fire, and to operate the fan motor through replacement of the modular protection device 100 at a low cost without replacing a relatively expensive fuse, There is an effect of preventing destruction of the fan motor and the resistor due to the fast cutting operation of the thermal fuse attached so as to accurately correspond to the current.

The fan register controller according to the present embodiment may be realized by integrally embodying the modular protection device 100 within the fan register controller or by controlling at least one stage of the fan register controller such as a high speed stage HI, Shaped connecting / disconnecting unit 230 (see FIG. 3) that can be connected to the grounding terminal (GND) can be formed on the housing so that the modular protection apparatus 100 can be easily attached to / detached .

FIG. 3 is an exemplary view illustrating a configuration in which a modular protection device 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 incorporating the modular protection device 100 into the fan register controller, or at least one stage of the fan register controller (e.g., high speed stage HI, low speed stage LO (Ground terminal (GND)), as shown in Fig.

In this case, when the modular protection device 100 is integrally implemented in the fan resistor controller, the modular protection device 100 can be implemented using a printed circuit board, and the printed circuit board can be installed in each operating mode (e.g., high speed mode, low speed mode, (Or terminals) that can be connected to the current supply wiring for driving the power supply lines (or terminals).

The printed circuit board may include a current sensing resistor 130 in addition to the thermal fuse 120. At this time, the current sensing resistor 130 may have different resistance values according to the current supply wiring for driving the fan motor in each operation mode (for example, high speed mode, low speed mode, etc.).

For example, when the normal current flows, the current sensing resistor 130 does not generate heat, but when the constraining current (i.e., an overcurrent generated when the fan motor is constrained) flows, ), The temperature fuse 120 (or the connection portion between the thermal fuse and the pattern resistor) is cut according to the temperature rise of the current sensing resistor 130.

The pattern wiring 110, the thermal fuse 120, and the current sensing resistor 130 are exaggerated for clarity of explanation. In actual application, the position and the shape of the pattern wiring 110, the thermal fuse 120, . ≪ / RTI > For example, the current sensing resistor 130 may be formed of a pattern resistor (i.e., a resistor printed in a pattern).

Meanwhile, when the modular protection device 100 is detachably mountable, a connector-shaped detachable attachment portion 230 is formed on the housing of the fan resistor controller so that the modular protection device 100 can be easily detached (or coupled) .

In addition, a separate case (not shown) surrounding the printed circuit board may be further included to easily attach the modular protection device 100 to the detachable unit 230 formed on the fan register controller. The case (not shown) may be formed in a hermetically sealed shape to protect the internal printed circuit board from external shocks, dirt, or moisture. When a case (not shown) is applied to the modular protection device 100, a terminal (that is, a connection terminal) for connecting to the current supply wiring should be implemented to be drawn out.

As described above, according to the present embodiment, the modular protection device 100, which is integrally implemented or detachably mounted inside the fan resistor controller, operates before the fuse operates to cut off the current flowing in the fan motor. Accordingly, it is possible to prevent the occurrence of a safety accident such as a fire, and to operate the fan motor through replacement of the modular protection device 100 at a low cost without replacing a relatively expensive fuse, There is an effect of preventing destruction of the fan motor and the resistor due to the fast cutting operation of the printed thermal fuse so as to accurately correspond to the current.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, I will understand the point. Accordingly, the technical scope of the present invention should be defined by the following claims.
