The electric drive unit 50 is a motor for providing a rotational force in the forward / reverse direction to the hinge support point of the foot board 20 to pivot the foot board 20 in the folding and unfolding direction with respect to the mounting bracket 10 52 is provided. At this time, the motor 52 is equipped with a drive gear 54 on the rotating shaft, the drive gear 54 is meshed with the driven gear 56 installed on the hinge pin (H), including the motor 52 The drive gear 54 and the driven gear 56 are preferably accommodated in the case 58 installed on the bottom surface of the mounting bracket 10.

It is provided with an overload protection circuit for controlling and especially preventing overload during operation.

To this end, the overload protection circuit switches the polarity of the voltage applied to the motor 52 of the electric drive unit 50 according to the signal provided from the signal input unit 30 to perform forward / reverse driving of the motor 52. The normal / reverse driving power supply unit CS to be adjusted, the normal on-type relay switch RS connected in series between the power supply unit CS and the one power terminal 52a of the motor 52, The first poly switch PT1 and the first diode D1 connected in series between the power supply unit CS and the relay switch RS are interposed between the power supply unit CS and the relay switch RS. The second poly switch PT2 and the second diode D2 connected in parallel with the first poly switch PT1 and the first diode D1, and the power supply unit CS and the motor 52, respectively. The first poly switch PT1, the first diode D1, and the second poly switch PT between the other power terminal 52b. 2) and a relay connected to the second diode D2 in parallel to turn off the relay switch RS when energizing the first poly switch PT1 or the second poly switch PT2 for a predetermined current or more, respectively. The coil RC is provided.

Accordingly, the control unit 40 according to the signal input from at least one of the manual operation switch 32, the door switch 34, the external transmitter 36 of the wireless door lock device the electric drive unit 50. The foot board 20 is pivoted in the unfolding or folding direction with respect to the mounting bracket 10 by adjusting the DC voltages applied to both power terminals 52a and 52b of the motor 52 of FIG.

For example, the control unit 40 controls the electric drive unit 50 when an opening signal according to the operation of the operation switch 32 is input and outputs a signal at the start of operation to the electric drive unit 50 so that the foot board ( 20 is unfolded, and when the closing signal according to the manipulation of the manipulation switch 32 is inputted, the foot board 20 is folded to its original state.

When the door open signal is input from the door switch 34 according to the opening and closing of the door 5 by the user, the control unit 40 controls the electric drive unit 50 to start operation of the electric drive unit 50. The foot board 20 is unfolded by outputting a signal, and when the door closing signal is input, the foot board 20 is folded back to its original state.

In addition, when the door open signal is input from the external transmitter 36 of the wireless door lock device, the control unit 40 controls the electric drive unit 50 to unfold the foot board 20, and the door close signal. When is input, the foot board 20 is folded to its original state.

That is, when an unfolding signal is input to the control unit 40 through the signal input unit 30, a positive DC voltage B + from the battery is transferred to the first poly switch PT1 and the first through the power applying unit CS. One diode D1, the c contact and b contact of the relay switch RS, the motor 52, and the ground terminal (E) of the power supply unit (CS) flows. At this time, some current also flows in the relay coil RC, but since this is not sufficient to magnetize the relay coil RC, the relay switch RS is in a switched-on state, i.e., the c contact and the b contact. Stay connected. As a result, the motor 52 is rotated forward to rotate the hinge pin (H) to rotate the foot board 20 in the unfolding direction.

On the contrary, when the folding signal is input to the control unit 40 through the signal input unit 30, the switching of the switching state is accompanied by the power applying unit CS, and through this, the DC voltage B + is moved in the opposite direction to the motor ( 52) and contacts b and c of the relay switch RS, the second poly switch PT2, the second diode D2, and the ground terminal E of the power applying unit CS. Accordingly, the motor 52 is rotated in the reverse direction to rotate the hinge pin (H) to rotate the foot board 20 in the folding direction.

If the foot board 20 is completely turned in the folding or unfolding direction with respect to the mounting bracket 10 during the series of processes, if the continuous operating power is applied to the motor 52, the motor 52 Since the state of the overload may cause damage to the motor 52, in view of the present invention, the relay switch (RS) is turned off via the relay coil (RC) when the motor 52 is overloaded You can do it.

That is, when the foot board 20 turns to the end in the folding or unfolding direction with respect to the mounting bracket 10 according to the driving of the motor 52, the motor 52 no longer rotates and stops. As voltage is continuously applied even in the state, the current value is increased due to overload.

As described above, when the current flowing in the motor 52 is increased, a voltage drop occurs while the internal resistance of the first poly switch PT1 or the second poly switch PT2 increases, thereby causing the relay coil RC to flow. As the current value increases, the relay coil RC is magnetized. According to the magnetization of the relay coil RC, the relay switch RS is switched off, that is, the c contact and the a contact are connected in the relay switch RS, and the current flow to the motor 52 is interrupted and the motor ( 52) is stopped. Thereafter, when an off signal is input by the user, the power applying unit CS is switched to the off state so that the current flowing to the relay coil RC through the battery is cut off, so that the relay coil RC is non-magnetized. Since the switch RS is originally switched on, that is, the state in which the c contact and the b contact are connected, the switch RS waits for input of an on signal by the next user.

For reference, the first and second poly switches PT1 and PT2 are employed as a temperature-responsive resistor element whose internal resistance varies with temperature, and the first and second poly switches PT1 and PT2 are connected to the temperature. Accordingly, since the resistance value is variable and the temperature exceeds a predetermined value, the self-switching function is used. The relay switch RS is used to protect the motor 52 from overcurrent when the relay switch RS does not normally perform an overcurrent blocking action. However, since the first and second poly switches PT1 and PT2 take a relatively long time to perform their own switching operation and a large amount of overcurrent may flow into the motor 52 during this time, the overcurrent interruption is performed by the relay switch RS. And the first and second poly switches PT1 and PT2 are used to assist in blocking an overcurrent in an emergency.

In addition, according to the polarity of the voltage (B +) applied from the battery to the motor 52, the direction of the current flowing through the motor 52 flows separately between the first diode D1 and the second diode D2. When the switching signal for unfolding the foot board 20 by the operation of the input signal is input to the signal input unit 30, the current is transferred from the battery through the power supply unit CS, the first poly switch PT1 and the first diode. (D1) flows to the c contact, the b contact, the motor 52, the ground terminal E of the relay switch RS, the motor 52 is driven forward rotation, while the user's operation of the foot board 20 When a switching signal for folding is input to the signal input unit 30, current is supplied from the battery through the power supply unit CS, the motor 52, the b contact point of the relay switch RS, the c contact point, and the second poly switch ( PT2), the second diode D2, and the ground terminal E flow to drive the motor 52 in reverse rotation.

At this time, when the foot board 20 is stopped at the unfolding position by the forward rotation driving of the motor 52 and the current value flowing in the motor 52 is high, the internal resistance of the first poly switch PT1 increases as the voltage increases. While the current value flowing through the relay coil RC rises and the relay coil RC is magnetized, the foot board 20 stops at the unfolding position by the reverse rotation driving of the motor 52 and the current value flowing to the motor 52. In the increased state, as the internal resistance of the second poly switch PT2 increases, the current value flowing through the relay coil RC increases, so that the relay coil RC becomes magnetized.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limited to the particular details of the embodiments set forth herein. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
