≪ 3. Characteristics according to the configuration of the electric drive apparatus according to the second embodiment of the present invention &

5A to 5F are diagrams for explaining characteristics according to the configuration of the electric drive system according to the second embodiment of the present invention,

The electric driving apparatus according to the second embodiment of the present invention shown in Figs. 5A to 5F means an electric driving apparatus that can be mounted on a curtain.

The electric driving apparatus according to the second embodiment of the present invention includes a driving unit driven by power supply, a receiving unit receiving a radio signal generated by the operation of the remote controller, and a driving unit driven by a command corresponding to a signal received by the receiving unit .

FIG. 5A is a plan view illustrating a cross section of the drive unit of the electric drive apparatus according to the second embodiment of the present invention.

The driving unit of the electric driving apparatus according to the second embodiment of the present invention includes a driving motor 510, a driving wheel 520, a driving shaft 515, a sensing unit 525, a sensing switch S, a braking member 540, A lifting member 545, a solenoid portion 530, and an elastic member 546.

The driving unit of the electric driving apparatus according to the second embodiment of the present invention may include a lid member 523, a fixing member 511, and a socket member 512.

The driving motor 510 is supplied with power and generates rotational motion.

The drive shaft 515 is provided between the drive wheel 520 and the drive motor 510 for shaft coupling.

The braking member 540, the elastic member 546 and the drive wheel 520 are axially coupled in the order of the drawing shown in Fig. 5A by the drive shaft 515. [

In some cases, the socket member 512, the braking member 540, the elastic member 5460, the driving wheel 520, and the lid member 523 are arranged in the order of the drawing shown in FIG. 5A by the drive shaft 515 As shown in FIG.

The braking member 540 moves along the axial direction of the drive shaft 515 and rises to allow the drive wheel 520 to brak.

The lifting member 545 is coupled at one end to the braking member 540 such that the braking member 540 is lifted along the drive shaft.

The solenoid portion 530 is engaged with the other end of the lifting member 545 so that the lifting member 545 is lifted.

The solenoid portion 530 includes a solenoid valve 531.

A description of the solenoid valve will be given later.

The elastic member 546 is provided between the driving wheel 520 and the braking member 540.

Referring to FIG. 5B, a process of braking the driving unit of the electric driving apparatus according to the second embodiment of the present invention will now be described.

If the control unit determines that the command corresponding to the radio signal received by the receiving unit is terminated in the state where the driving unit is driven, the control unit causes the solenoid unit 530 to receive the current so that the solenoid valve 531 is pulled upward ).

Thus, the solenoid valve 53 is connected to the solenoid valve 53 so that the lifting member 545 is lifted up (m520).

Then, the braking member 540 in which the raising member 545 is formed is caused to rise along the drive shaft 515 (m530).

The engaging member formed on the braking member 540 engages with the insertion groove of the driving wheel 520 to allow the driving wheel 520 to brak.

When the driving wheel 520 is braked, the control unit stops supplying the current to the solenoid unit 530.

When the operation of the solenoid portion 530 stops, the elastic member 546 causes the engaging member to be disengaged from the insertion groove (m540).

Then, the braking member 540 causes the lifting member 545 to be lowered (m550), so that the lifting member 545 causes the solenoid valve 531 to return downward (m560).

Referring to FIG. 5C, the driving wheel 520 is connected to the curtain so that the connecting cord L, which allows the curtain to be opened or closed, is wound around the outer periphery of the turning radius.

In addition, the connection cord L wound on the driving wheel 520 crosses left and right to be wound on the sensing means 525. The reason for this and the driving wheel 520 and the sensing means 525 will be described later in detail.

On the other hand, the electric drive apparatus according to the present embodiment may include a socket fixing member 513.

Therefore, the socket member 512, which is axially coupled to the driving wheel 520 and the braking member 540 through the drive shaft, can be fixed by the socket fixing member 513.

Referring to FIG. 5D, the sensing means 525 senses an open, closed, or engaged state of the curtain.

The tension of the connecting strap L wound on the driving wheel 520 is maintained and the connecting straps L are crossed to increase the contact force and the contact area between the connecting strap L and the driving wheel 520 , And between the curtain and the driving wheel 520.

The sensing switch S is formed on the left and right sides of the sensing unit 525. When the sensing unit 525 senses the open state, the closed state, or the engagement state of the curtain, the sensing unit 525 sends a signal to the control unit .

In this embodiment, the open state or the closed state of the curtain means the fully opened or closed state of the curtain.

The process of sensing the opening state, the closing state, or the hooking state of the curtain will be described in detail as follows.

When the opening state of the curtain, the closed state, or the hooking state occurs, the connecting string L of the curtain is not moved, and only the driving wheel 520 is continuously driven with the tension of the connecting string L of the curtain being maintained The tensile force applied to the connection cord L wound on the sensing means 525 increases and the sensing means 525 moves to the left or right.

For example, when the driving wheel 520 is driven in the clockwise direction (m620), when the opening state, the closing state, or the locking state of the curtain is generated, the sensing means 525, (M640).

When the sensing means 525 moves to the left, the sensing switch S operates and sends a signal to the control unit.

Then, the control unit causes the driving unit to be braked. (The process of braking the driving unit by the control unit has been described above.)

Even when the driving wheel 520 is driven in the counterclockwise direction (m610), the sensing means 525 moves to the right (m630).

5C and 5E, the driving wheel 520 includes a plurality of asymmetric projecting members 522 along the outer periphery of the turning radius so that the connecting strap L is inserted in the longitudinal direction But they are staggered to increase the contact force.

An insertion groove 521 is formed in the width direction along the circumferential direction. The insertion groove 521 is formed with an inner jaw along the inner circumference of the driving wheel 520.

The locking member 541 formed on the braking member 540 is extended in the direction of the insertion groove 521 so as to be inserted into the insertion groove 521 to stop driving the driving wheel 520, And the upper surface bent to be inserted into the insertion groove 521 for easy insertion is curved.

The lower surface of the engaging member 541 is bent so that the length of the lower surface of the engaging member 541 is released from the insertion groove 521 by elastic force.

The protruding members 522 of the driving wheel 520 are provided in a plurality of asymmetric rows and the driving wheel 520 crosses the connecting cord L by the sensing means 525 in the left and right directions. So that the electric driving device can more easily open and close the curtain.

The one end of the upper end of the protruding member 522 is formed in a curved line so as to minimize the damage of the connecting strap L when the connecting strap L is bound and separated.

The upper end of the engaging member 541 is formed in a curved shape so that the driving wheel 520 can be rotated in a state in which the braking member 540 does not return to the position before fully lifted by the elastic member So that there is no problem in manually opening and closing the curtain even if the electric driving device is mounted and used.

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 limiting the scope of the invention as defined by the appended claims. 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 invention.
