The present invention automatically raises and lowers the bladder that controls the amount of shading of the shading light, which is attached to the window, and visually blocks the indoor and outdoor sides, and horizontally or vertically (blinds) the blind shade blades. The present invention relates to an electric blind driving device for converting strength, and in particular, by improving the structure of the driving device, the driving force of the motor is accurately transmitted to the lifting wire and the angle adjusting wire, so that the lifting and lowering of the sunshade wing is smooth and sunshade. It is an electric blind driving device developed for the purpose of providing high-quality products with the convenience of using and extending the lifespan effect, and the shading reliability can be improved. .

In general, as the sunshade device that controls the amount of sunshine, a number of sunshade wings are typically spoken up and down as lifting and lowering wires and angle adjusting wires, and each sunshade wing is raised and lowered by the forward and reverse rotational power of the motor. Vertical or horizontal adjustment to adjust the amount of sunshine appropriately, such as the blade wing lift, lower and angle adjustment is introduced by the manual operation that the user operates by directly pulling or releasing the wire, and the motor showing the reverse driving force In addition, a reduction gear for transmitting the driving force of the motor, the reduction gears of the forward and reverse driving force of the motor through the reducer to increase and decrease the blind sunshade wings, the pulley for converting the angle, the electric motor is composed of a combination of the wire is introduced. Bar, in the conventional electric blind drive device, a constant force on the pulley constituting the operating portion When the phase is applied, a pair of angle adjustment wires are connected at regular intervals on both ends of the winding spring (spring) wound so that rotation is blocked by slip resistance when the pressure is applied below a certain force. It is wound separately on the pulley (a pulley in which the angle adjusting wire is wound), and each wire is a structure connected to each awning wing in a normal manner, and the pair of angle adjusting wires are vertically moved in opposite directions by the rotational force of the motor. Each sunshade wing connected to it is adjusted vertically (or inclined) or horizontally and completely shaded with both sunshade wings being vertical, and the sunshade wing is fully open while the sunshade wings are all horizontally adjusted. It was to control the amount of sunshine.

In addition, the opening and closing operation of the blind sunshade wing causes the sunshade wing to move up and down as the wire for lifting and lowering is wound or unwinded by the forward and reverse rotation of the motor.

However, in such a conventional blind, the wire for angle adjustment is connected to the winding winder on the pulley, and during the angular displacement of the sunshade wing, the pulley is rotated by the slip resistance between the spring and the pulley so that the pulley is rotated. Although the angle can be adjusted, when the pulley is rotated more than a certain angle by the rotation of the motor, that is, when the sun blade is rotated more than the maximum in the vertical or horizontal angle adjustment, the force acting on the mainspring is The friction spring is generated as the spring is idling in the slip state because it is operated more than the slip resistance.

Accordingly, it is impossible to adjust the angle of the sunshade wing because the wear resistance is generated due to frictional force at the part where the spring of the pulley is wound and the slip resistance is lost during long-term use. It was not easy to use it because it was impossible to adjust or maintain the adjustment angle of the sunshade blade.

Therefore, in order to solve the above-mentioned drawbacks of the present invention, the driving force of the motor is accurately transmitted to each of the elevating wire and the elevating wire when the blind sunshade wing rises and falls and the angle change of the sunshade wing is performed. As the lifting, lowering and angle adjustments are made in a stable state, the lifting and lowering operation is smooth, and it is designed to accurately adjust and maintain the angle of the sunshade blade. As follows.

A plurality of sunshade wings 1 are addressed to the lifting and lowering wires 2 and the angle adjusting wires 20, and each of the wires 2 and 20 is wound on a spool 4 arranged in the motor 3. In the general blind for adjusting the amount of sunshine as the sunshade wing is moved up and down and the horizontal and vertical state in accordance with the forward and reverse rotation of the motor, the locking jaw (5a) is protruded on the outer peripheral edge, the internal gear having a gear formed on the inner surface (5), the prime gear (6) located in the center of the internal gear (5), the plurality of pin gears (7) and pin pins (7) that are engaged between the internal gear (5) and the prime gear (6). Spool (4) is connected to the projection (4a), and the fixed bracket (8) (80) and the fixed bracket to be coupled to one side of the internal gear (5) and the spool (4) respectively (8) (80), the pulley assembly is composed of a rotating jersey bar (9) which is fixed to the internal gear (5) the locking jaw (5a) while blocking the rotation of the internal gear (A) is fabricated and provided, the pulley assembly motive gear 6 is coupled to the shaft member 3a of the motor 3 by the key means B, and the position is installed inside the cover 10, but the internal gear locking step ( The sunshade wing angle adjustment wire 20 is connected to 5a), and the spool 4 has the structure which connected the raising and lowering wire 2 to it. Here, each wire (2) 20 is connected in a navigable manner to the sunshade wing (1) of each blind through the hole of the cover (10).

The projection 4a of the spool 4 is inserted into the hole 7a formed in the center of the pinch gear 7. The shaft member 3a of the motor 3 is coupled to the motive gear 6 through the hole of the fixing bracket 8.

Referring to the effect of the present invention configured as described above are as follows. Looking at the horizontal and vertical (inclined) operating relationship of the blind shade blade (1), (the state of Figure 3 (a) for the sake of convenience, the shade blade is adjusted horizontally, the figure 3 (b) It is assumed that the sunshade wing is adjusted vertically (inclined) .In addition, the forward rotation of the motor is made in the direction of arrow R (left to right), and the reverse rotation is made in the direction of arrow L (right → left). First, when the motor 3 is rotated forward in the direction of arrow R as shown in FIG. 3 (a), the motive gear 6 is rotated in the rotation direction of the motor, and the pinch gear 7 is in the motor rotation direction. It rotates in the reverse direction, the internal gear 5 is rotated in the direction of the arrow K, and if the motor 3 is rotated in the reverse direction to rotate in the direction of the arrow "L" as shown in FIG. ) Is rotated in the rotational direction of the motor, the pin gear 7 is rotated in the reverse direction of the motor rotational direction, Folding control 5 is rotated in the arrow M direction.

Therefore, the pair of awning wing angle adjusting wires 20 fixed to the locking step 5a of the internal gear 5 are vertically inclined (horizontally) or horizontally to each awning wing 1 connected thereto while vertically moving in opposite directions. Adjust

In other words, when the motor 3 rotates forward (arrow R direction: left to right) in the state of FIG. 3 (a), the internal gear 5 rotates in the direction of the arrow K and rotates in the same state as (b). Since the pair of angle adjusting wire 20 is moved vertically in the opposite direction as shown in P, P1 of FIG. 3 (a) of the drawing, the awning wing 1 is angularly converted to a vertical (inclined) state. When the motor 3 rotates in reverse direction (arrow L: right to left) in the state of 3 (b), the internal gear 5 rotates in the direction of the arrow M and moves to the same position as the third drawing in the drawing (a). As the angle adjusting wire 20 is vertically moved in the opposite direction to each other as shown by arrows 0 and 01 in FIG. 3 (b), the sunshade wing 1 is angle-controlled in a horizontal state.

With this operation, the sunshade wings 1 are completely shielded in the vertical (tilt) state as shown in the third drawing (b), and the sunshade wings 1 are fully opened in the horizontal state as shown in the third drawing (a) in the drawing. When it is in a state of being adjusted, the amount of sunshine is controlled by appropriate adjustment.

Here, as the internal gear 5 rotates as described above, the spool 4 is in a state of being suspended by the blind shading wing 1 through the lifting and lowering wire 2 so that the rotation is stopped by the blind load. For this reason, the pin gear 7 is rotated in the opposite direction to the rotation direction of the motor 3 without shifting the position inside the internal gear 5 with the projection 4a of the spool 4 as the center axis.

On the other hand, as the internal gear 5 is rotated by the driving of the motor 3, the internal gear locking jaw 5a is attached to both side fixing brackets 8 and 80 as shown in FIG. 3 (a) (b). The internal gear 5 is not rotated when the fixed support rod 9 is caught. (Here, for convenience, the locking jaw (5a) of the internal gear (5) on the rotary stopper (9) is a state in which the sunshade wing is converted to the horizontal state, the state caught in the state shown in FIG. (b) The sunshade blade 1 is inclined or vertical in the state of being caught in the state of

In addition, when the sunshade wing is angularly converted as described above and the motor 3 is driven continuously while the rotation of the internal gear 5 is stopped, it is coupled to the motor shaft member 3a by the key means B. The prime move gear 6 is rotated, and at the same time, a plurality of pin gears 7 engaged with the prime move gear 6 are rotated in the internal gear 5 in which rotation is stopped.

Therefore, the spool 4 coupled to the holes 7a of the plurality of pin gears 7 through the self protrusions 4a rotates in the rotational direction of the motor 3, so that the lifting and lowering wires 2 Winding or unwinding, the sunshade wing (1) is smoothly lifted (opened) or lowered (closed) to perform the normal blind sunshade wing, closing operation.

This will be described in more detail as follows.

Here, for convenience, it is assumed that the motor 3 operates in reverse rotation (right to left in the direction of the arrow L) when the blind is opened, and the motor 3 operates in forward rotation (left to right in the direction of the arrow R) when the blind is closed. .

That is, when the user turns on the reverse rotation switch (not shown in the drawing) to open the sunshade wing of the blind, the prime mover 6 is reversed and the pinch is rotated as the motor 3 reverses (right to left). Since the gear 7 is rotated from left to right, the internal gear 5 is rotated from left to right. In this process, the spool 4 is stopped by the blind load.

At this time, the sunshade wing 1 is angled vertically (inclined) (in Figure 3 (b) in the same operation as described above the internal gear 5 is rotated from left to right to the sunshade wing all 1 Adjusting in a horizontal state and at the same time the locking jaw (5a) and the rotating support bar (9) is caught as shown in Figure 3 (a), and, even in the state before the opening of the sunshade wing (1) is adjusted to the horizontal state Since the locking step 5a of the internal gear 5 and the rotary stop bar 9 are engaged with each other as shown in FIG. 3 (a), the sunshade wing is horizontal. (5) is in the state of rotation stop.

In this state, the motor 3 is continuously rotated in reverse direction (right to left), and the internal gear 6 is rotated and the plurality of pin gears 7 engaged with the primary gear 6 rotate at the same time. 5) is moved from the right side to the left side, and accordingly, the spool 4 coupled to the plurality of pin gears 7 via the projections 4a is rotated in the rotational direction of the motor 3 for lifting and lowering. As the wire 2 is wound around the spool 4, the sunshade wing 1 is moved upward. When the movement is completed, the power supply is cut off by a predetermined sensing means, and at the same time, the driving of the motor is cut off. The operation is completed.

In addition, when the user turns on the forward-only switch (not shown in the drawing) to close the sunshade wing of the blind, the prime mover 6 rotates forward as the motor 3 rotates forward (left to right), Since the internal gear 5 is rotated from the right side to the left side, the pin gear 7 is rotated from the right side to the left side while angle-shifting all of the sunshade blades 1 which are folded and opened horizontally as described above. As shown in FIG. 3 (b), the locking step 5a of the internal gear 5 is caught by the rotation support rod 9, and the internal gear 5 is in a rotationally stopped state. In this process, the spool 4 is rotated and stopped by the load of the blind, and even in this state, the motor 3 is rotated forward by continuously performing the forward rotation (left to right). At the same time, a plurality of pin gears 7 meshed with the prime gear 6 are engaged with the internally-rotated gear 5 that has been rotated and then moved from left to right.

Accordingly, since the spool 4 coupled to the plurality of pin gears 7 through the projection 4a is rotated from left to right, the lifting and lowering wire 2 wound on the spool 4 is unwinded and the blind shade blades 1 ) Is unfolded by the load and descending without difficulty.

When the lowering is completely completed in the descending process of the blind shading wing (1), the power supply is cut off by a predetermined amount of sensing, at the same time the motor drive is stopped to complete the normal blind closing operation.

On the other hand, if you want to arbitrarily adjust the opening of the blind shade blade (1) or the angle adjustment of the closed section and the shade blade (1), by pressing the forward or reverse rotation switch in a speedy manner, Can be selectively adjusted accordingly.

As can be seen from the above, the present invention is a blind drive device that folds and closes the sunshade wing of the blind in a folding manner and arbitrarily adjusts the angle of the sunshade, such as an internal gear, a pinchgear, a prime mover, a rotary support rod, and the like. It is equipped with a pulley assembly combined with and connected to the motor, so that the driving force of the motor is transmitted to the blind wires and the angle wires at the time of angle conversion during closing. It can be made smoothly and smoothly, and it can maintain and adjust the angle of the sunshade accurately. It is convenient to use and can be used for a long time.
