Description

Automatic curtain drive unit {AUTOMATIC CURTAIN DRIVING UNIT}

The present invention relates to an automatic curtain driving device, and more particularly, to an automatic curtain driving device that can accurately detect a jam during full opening / closing of a curtain to prevent damage to the device.

In general, homes and offices are equipped with curtains for the purpose of privacy, mining and heating. Curtains are made of fabric, and curtains can be opened and closed from side to side, vertical can be opened and closed / adjustable angle, and blinds can be opened and closed.

In order to operate such a curtain, the user must grab and pull the left and right opening and closing wires and the angle adjusting wire by hand, which is inconvenient to move to the installation place of the curtain.

In addition, when the wires for right and left opening and closing, the angle adjustment wires are made in orbit, each wire is seen in two lines. Here, two lines of wire (one for opening and one for closing) are designed to behave differently, but since each line is not marked for operation, pull the two lines of wire once to check the operation of the curtain. After checking, there is an inconvenience to pull the wire.

In order to solve the problem of the manual curtain has been proposed an electric curtain driving device that can drive the curtain from a distant place without the user moving to the curtain installation place. As a curtain electric switchgear, a blind automatic switchgear of Korean Patent Application No. 10-1999-36014 and a domestic electric curtain of Korean Patent Application No. 10-2000-50574 have been proposed.

The technical gist of the earlier application will be briefly described below.

In the blind automatic opening and closing device of Korean Patent Application No. 10-1999-36014, the blind provided with the opening and closing string and the direction adjusting string, the drive motor for forward / reverse rotation according to the input operation control signal, and the drive motor Rotating part for rotating the opening and closing string according to the rotation, and the reduction gear that is connected to the rotating part and formed with a plurality of fixed holes along the circumference does not become one rotation even when the blade is moved to the longest distance, and inserted into the fixing hole An opening and closing drive unit configured to include a plurality of fixing pins and a switch which stops the rotation of the motor when the fixing pin is in contact with the fixing pin; Drive motor for forward / reverse rotation according to the input operation control signal, a plurality of fixing grooves are formed on the outer periphery for the direction adjusting strap is formed, the rotating roller for rotating the direction adjusting strap in accordance with the rotation of the drive motor, and for direction adjustment A portion between the plurality of stop balls installed on the string to control the direction adjustment range of the blind and the plurality of stop balls of the direction adjusting string wound around the outer circumference of the rotating roller by a hollow formed in the center are respectively wound to push the stop ball inwards. A direction adjusting drive unit including a stopper which is returned to its original position when the pushing force of the stop ball is removed after moving by a predetermined distance, and a switch which stops the operation of the driving motor when contacted with the stopper; A remote controller is provided to allow a user to select an operation mode (open / close mode, direction control mode) of the plurality of driving units, and outputs a predetermined wireless signal according to the selected key, and a wireless signal output from the remote controller. Receiving unit for receiving and outputs a wired signal corresponding thereto; The control unit is configured to output an operation control signal corresponding to the driving motor of the plurality of driving units based on the signal output from the receiving unit so that the blind is opened or closed according to the user's selection.

According to the above-mentioned application, when the fixing pin is in contact with the switch while the reduction gear is rotated by the rotational force of the driving motor, it is determined that the blind motor is positioned at the rightmost or leftmost side, and the driving motor is stopped. Here, the reduction gear is not rotated even if the blind moves to the longest distance can restrain the movement of the blind, but the size of the reduction gear should be changed according to the installation distance of the blind. Therefore, since the size of the reduction gear varies depending on the moving distance of the blind, the parts cannot be shared, and since the reduction gear is limited, the practicality is inferior.

In addition, there is a problem that the driving motor is overheated because the driving motor is continuously driven even if foreign matter is caught in the rail while the blind reaches the rightmost side or the leftmost side when the blind moves, or the blind overlaps.

In addition, the opening and closing strap is wound around the driving roller rotated by the driving motor while being supported by the pressing roller, and is configured to rotate by friction force when the driving roller rotates, but the driving roller and the pressing roller have a surface contact structure. The frictional force is weak, and therefore, there is a problem that a malfunction may occur in which the opening and closing strap does not rotate even when the driving roller is rotated.

In addition, the domestic electric curtain of Korean Patent Application No. 10-2000-50574, the controller unit consisting of a forward / reverse rotation motor, a power transmission device, a control circuit board, an open / close detection device; An extruded aluminum rail having a positioning hole; An aluminum connecting portion including a connecting plate having a double center hole which can adjust a distance; It consists of a tension line pull. The opening / closing detection device is configured such that the microcomputer stops the electric motor when a curtain is brought into contact with the opening / closing pressing device that is inserted into the tension line lead-out part side of the controller section so as to generate a signal.

According to the previous application, if the curtain is perpendicular or horizontal to the window when adjusting the angle of the curtain, the curtain contacts the open or closed pressing device and the microcomputer stops the electric motor based on this contact signal. Although it prevents overheating, if it is forcibly stopped while the curtain is opened and closed, the electric motor may be continuously driven and overheated, and it may be damaged by a separate opening / closing device. have.

The present invention is to solve the above problems, to provide an automatic curtain driving device that can accurately detect the jam during the full opening / closing of the curtain by using a simple structure, and stop the operation of the device. have.

Another object of the present invention is to increase the frictional force between the left and right opening and closing wires and the rotating means for rotating the wires to prevent the wire from slipping.

<Example 1>

Another example of the wire drive wheel, Figure 5b is an exploded view of the drive wheel applied to Figure 5a, Figure 5c is a state diagram of the installation of the drive wheel applied to Figure 5a.

As shown in FIG. 1, the automatic curtain driving device 100 according to the present invention includes a driving wheel 20 and an idle wheel for rotating the driving means 10 and the curtain opening and closing wire 1 forming an endless track. 30, a completely open / close detection means 40 for detecting a jam phenomenon during the full opening / closing of the curtain, and a signal by a wireless signal and a complete opening / closing detection means by an operation of a remote controller (not shown). It comprises a control unit (not shown) for controlling the drive means on the basis.

The drive means 10 is composed of a drive motor 11 and first and second power transmission gears 12 and 12a for transmitting the rotational force of the drive motor 11 to the drive wheel 20.

One side of the first movable plate 13 is rotatably installed, and a through hole is formed through the driving shaft 11a of the driving motor 11 at approximately the center thereof.

The first and second power transmission gears 12 and 12a are installed on the first movable plate 13 so that they can be idled and remain separated from the first drive gear 11b and the driving wheel 20. By the movement of the movable plate 13, either one is engaged with the first drive gear 11b and the drive wheel 20.

Both sides of the first movable plate 13 may include: first and second movable plate 13 moving one of the first and second power transmission gears 12 and 12a to be engaged with the first driving wheel 20; Two solenoids 14 and 14a are provided.

In this case, when the first and second power transmission gears 12 and 12a and the driving wheel 20 are separated from each other, since the driving wheel 20 is not bound by the driving motor 11, the user may manually operate the first and second power transmission gears 12 and 12a. The curtain 1 can be opened or closed by manipulating the wire 1.

Manual opening and closing of the curtain, as shown in Figure 2, to form a socket (20b) having a polygonal wrench groove (20a) in the drive wheel 20, by inserting the polygon wrench (T) in the wrench groove (20a) wrench (T ) Can be made by the method of turning.

As shown in FIG. 2, the wire opening / closing drive wheel 20 and the idle wheel 30 have a plurality of vanes 21 and 31 formed on the outer circumferential surface of the vane 21 and 31, respectively. ) Are installed so as to cross each other, and gear portions 22 and 32 that are engaged with each other are formed at one end. Wire seating grooves 21a and 31a may be formed at ends of the vanes 21 and 31. As a result, the opening and closing wire having a circular cross-section and frictional force are increased to prevent the phenomena in which the first wire 1 does not rotate when the driving wheel 20 and the idle wheel 30 are rotated.

As shown in FIG. 1, the opening / closing detection means 40 includes a first guide wheel 41 and an idle wheel, which are installed to be idled through a fixed shaft 41a on one side of the idle wheel 30. One end of the rod 42 is rotatably installed between the 30 and the first guide wheel 41 so that two portions of the opening and closing first wire 1 are wound so as to cross the first wire 1. The first switch operating wheel 43 revolves around the one end of the first rod 42 by the tension generated in the) and, as shown in FIG. 3, the movement of the first switch operating wheel 43. The first switch operating member 44 and the first switch operating member 44 interlocked with each other, and the first and the second switches operating on and off by the first switch operating member 44 when the curtain is opened / closed. Limit switches S1 and S2 are included.

One end of the first rod 42 is preferably rotatably coupled to the fixed shaft 41a of the first guide wheel 41.

As shown in FIG. 3, the first switch actuating member 44 includes a first switch actuating lever 45 extending from the bottom of the first switch actuating wheel 43 and the first switch actuating wheel 43. The first switch operating piece 46 is installed at the bottom and includes a guide hole 46a through which the first switch operating lever 45 is movably inserted. The first switch operating piece 46 is moved from the time when the first switch operating lever 45 is moved by a predetermined distance and is caught by the catching portions 46b and 46c at the end of the guide hole 46a, so that the first and second limit switches ( S1) (S2) is turned on. In this case, since the movement distance of the 1st switch operation wheel 43 can be reduced by the guide hole 46a of the 1st switch operation piece 46, the size of an apparatus can be reduced.

In this case, when the moving radius of the first switch operating wheel 43 is short, the driving motor 11 is stopped even in a temporarily stopped state, thereby sufficiently securing the moving radius of the first switch operating wheel 43 to prevent such a malfunction. Preferably, as an example, the size of the first guide wheel 41 may be smaller than the idle wheel 30 while the idle wheel 30 is larger than or equal to the size of the idle wheel 30.

Although not shown in the drawings, the automatic curtain driving device according to the present invention is installed in the installation space via the case.

The operation of Embodiment 1 according to the present invention configured as described above is as follows.

According to the automatic curtain driving apparatus according to the present invention, the curtain can be opened and closed automatically by operating the remote control, and the user can open and close the curtain manually.

As shown in FIG. 1, since the power transmission gears 12 and 12a are in a neutral state not engaged with the driving wheel 20 for opening and closing, the idle wheel 30 on which the first wire 1 is wound is driven motor 11. Since it is not bound, the curtain can be opened and closed by inserting the wrench (T) into the wrench insertion groove (20a) of the drive wheel 20 by turning the wrench (T).

When the curtain is automatically opened and closed by operating the remote controller, when a button of the remote controller is selected to open the curtain in a closed state, a wireless signal is transmitted from the remote controller, and the controller converts the wireless signal into an electrical signal to drive the driving means.

As shown in FIG. 4B, the controller applies a current to the first solenoid 14 so that the first power transmission gear 12 is engaged with the first driving gear 11b and the driving wheel 20 for opening and closing. The plate 13 is moved, and at the same time, positive polarity is given to the drive motor 11 (see FIG. 1) so that the first drive gear 11b is rotated in one direction.

The rotational force of the first driving gear 11b is transmitted to the driving wheel 20 through the gear portion 22 engaged with the first power transmission gear 12 so that the driving wheel 20 is rotated, and the driving wheel 20 is rotated. The idle wheel 30 meshed with is rotated together.

The first wire 1 wound around the idle wheel 30 is rotated by the rotational force of the driving wheel 20 and the idle wheel 30, and the first wire 1 is alternately arranged with vanes 21 and 31 interposed therebetween. Since the frictional force is maintained by being inserted into the wire seating grooves 21a and 31a (see FIG. 2) of the wedges, the frictional force is rotated without slipping.

The left and right opening and closing first wire 1 is smoothly rotated without being guided by the switch operating wheel 43 and the first guide wheel 41.

On the other hand, when the curtain is fully opened or caught during the movement and no longer moving, as shown in FIG. 4B, the curtain is not moved but the driving wheel 20 is continuously rotated by the rotational force of the driving motor 11. Based on the advancing direction of the wire 1, a strong tension is applied to the A portion of the wire 1 that does not pass through the idle wheel 30, so that the A portion is taut, and conversely, Part B is loose because part B has relatively little tension. Accordingly, the tension causes the first switch operating wheel 43 to revolve through the first rod 42 to move from the state of the virtual line to the state of the solid line, and to move the first switch operating wheel 43. As shown in FIG. 3, the first switch operating lever 45 at the bottom thereof moves along the guide hole 46a of the first switch operating piece 46, and the first switch operating lever 45 is guided. The first switch operating piece 46 is moved together with the first switch operating lever 45 from the moment it moves along the ball 46a and comes into contact with the one end engaging portion 46b of the first switch operating piece 46. 1 Turn on the limit switch (S1).

When the first limit switch S1 is turned on, the control unit determines that the curtain is completely open or is caught during the movement to stop the driving motor 11, and cuts off the current applied to the first solenoid 14 so that the first power is reduced. Move the transmission gear 12 to the neutral position. Since the engagement of the first power transmission gear 12 may not be released when the first movable plate 13 moves, after the driving of the driving motor 11 is stopped, the first driving gear 11b is reversed only by a predetermined period. Direction so that the first power transmission gear 12 is pushed from the first drive gear (11b) to be separated from the drive wheel (20).

On the contrary, when the button of the remote controller is selected to close the curtain, the receiving unit detects this and the control unit applies a current to the second solenoid 14a as shown in FIG. 4C to drive the second power transmission gear 12a for opening and closing. The first movable plate 13 is moved to engage the wheel 20, and at the same time, the negative drive is imparted to the driving motor 11 (see FIG. 1) so that the first driving gear 11b rotates in the reverse direction. .

The rotational force of the driving motor 11 is transmitted to the driving wheel 20 through the second power transmission gear 12a so that the driving wheel 20 is rotated, and the idle wheel 30 is driven by the rotational force of the driving wheel 20. It is rotated to rotate the wire (1). As the first wire 1 rotates, the curtain closes slowly.

On the other hand, when the curtain is completely closed or closed while being closed, the driving wheel 20 is continuously rotated by the rotational force of the driving motor 11, but since the first wire 1 is not moved, it is shown in FIG. 4C. As described above, a strong tension is applied to the portion B of the first wire 1 that does not pass through the idle wheel 30 when the traveling direction of the first wire 1 is referred to, so that the portion B becomes taut and the idle wheel ( Part A loosens because part of tension A is hardly applied to part A after 30). Accordingly, the tension of the first switch operating wheel 43 is rotated about the fixed shaft 41a of the first rod 42 while moving from the state of the virtual line to the state of the solid line, as shown in FIG. As described above, the first switch operating lever 45 at the bottom thereof is moved along the guide hole 46a of the first switch operating piece 46 by the movement of the first switch operating wheel 43. From the moment when the lever 45 moves and contacts the other locking portion 46c of the first switch operating piece 46, the first switch operating piece 46 is moved together with the first switch operating lever 45 to move the second. Turn on the limit switch (S2).

When the limit switch S2 is turned on, the control unit determines that the curtain is completely closed or jammed to stop the driving motor 11, and cuts off the current applied to the second solenoid 14a to cut the second power transmission gear 12a. ) To the neutral position.

Since the engagement of the second power transmission gear 12a may not be released when the first movable plate 13 moves, the first driving gear 11b is rotated in the opposite direction after the driving of the driving motor 11 is stopped. The second power transmission gear 12a is pushed from the first drive gear 11b so as to be separated from the driving wheel 20.

Figures 5a, 5b and 5c is a perspective view, a wire wound development and installation state diagram of another embodiment of a drive wheel applied to the automatic curtain drive device according to the present invention, respectively.

As shown in FIG. 5A, the driving wheel 50 has vanes 51 and 52 formed on opposite sides of its outer circumferential surface, respectively, having inclined portions 51a and 52a and vertical portions 51b and 52b. ) Are zigzag arranged in two lines in the circumferential direction, and the gear portion 53 is formed at one end.

As shown in FIG. 5B, the wire 1 descends toward the outer circumferential surface side of the driving wheel 50 along the inclined portions 51a and 52a facing the driving wheel 50 and is arranged in a zigzag form. It is wound in a meandering shape by the 52, and tightened in opposite directions by the facing vertical portions 51b and 52b, so that the friction force is very large, so that the wire is not rotated and rotated when the driving wheel 50 is rotated. Malfunctions are prevented.

Therefore, the driving wheel 50 does not need an idle wheel for rubbing the wire 1 to the driving wheel 50 because the friction force with the wire 1 is large, as shown in Figure 5c, even if only one wire is installed (1) can be rotated without slipping.

<Example 2>

The automatic curtain driving device according to the second embodiment is applied to a curtain (called a vertical) capable of opening and closing and angle adjustment.

The second wire for angle adjustment is formed at the end of the vane 61. A ball catching portion 61a is provided in (2) to which the balls 2a coupled at a predetermined interval are separated so as to be distinguishable from the first wire 1.

The second driving means may be configured to drive the driving wheel 60 by a separate driving motor, and the first and second driving wheels 20 using one driving motor 11 to rotate the driving wheel 20. 60 may be configured to operate, but the latter is employed in the present invention to reduce the number of parts.

That is, the second driving means is provided with a height difference from the first driving gear 11b on the second movable plate 13a, one end of which is rotatably installed, and the driving shaft 11a of the driving motor 11. The second drive gear 11c and the second drive gear 11c disposed above the second movable plate 13a and the second movable plate 13a are installed on the second movable plate 13a so as to be idled, respectively. Third and fourth power transmission gears 15 and 15a selectively engaged with the third and fourth solenoids 16 provided on both sides of the second movable plate 13a to move the second movable plate 13a, respectively. 16a).

The angle opening / closing detection means having the same structure as the opening and closing means is also applied to the angle adjusting means. That is, as shown in Figure 6, the angle opening / closing detection means, the second guide wheel 71 is installed on the fixed shaft 41a of the first guide wheel 41 on one side of the drive wheel 60 so as to be idle. ) Between the second driving wheel 60 and the second guide wheel 71 is rotatably installed on the second rod 72 having one end rotatably fixed, and the second wire 2 is wound so as to cross each other. The second switch operating wheel 73 revolves about one end of the second rod 72 by the tension generated in the second wire 2, and as shown in FIG. 73 is installed on both sides of the second switch operating member 74 and the second switch operating member 74 to be interlocked according to the movement of the switch, and is turned on by the second switch operating member 74 when the curtain is opened / closed. It includes a limit switch (S3) (S4) actuated.

The operation according to the second embodiment of the automatic curtain driving apparatus according to the present invention configured as described above is as follows.

Vertical opening and closing and angular opening and closing of the vertical drive one drive motor 11, but the first and second movable plates 13 and 13a are operated only in each mode. That is, only the first movable plate 13 is operated at the left and right opening and closing, and only the second movable plate 13a is operated at the angle opening and closing.

In the case of vertically opening and closing the vertically by operating a button of the remote controller, as shown in FIGS. 4B and 4C, the first movable plate 13 is rotated by the first and second solenoids 14 and 14a to rotate the first and second power. Any one of the transmission gears 12 and 12a is engaged with the drive gear 11b and the left and right driving wheels 20. By applying the positive / negative polarity to the driving motor 11 to impart rotational force in one direction, rotating the driving wheel 20 to open and close the curtain left and right is the same as that of the curtain left and right, as shown in the first embodiment. It will be omitted.

On the other hand, if the button of the remote control is selected to open the vertical angle of the vertically closed window and the right angle to the window, the control unit applies a current to the third solenoid 16 as shown in FIG. The second driving plate 13a is moved so that the three power transmission gear 15 is engaged with the second driving wheel 60, and the positive polarity is given to the driving motor 11 (see FIG. 6) to drive shaft 11a. Let it rotate forward.

By the movement of the second movable plate 13a, the third power transmission gear 15 is engaged with the drive gear 11c and the second drive wheel 60 so that the rotational force of the drive shaft 11a (see FIG. 6) becomes the third. The second driving wheel 60 is rotated by the power transmission gear 15 to the second driving wheel 60, and the second hanging wheel 60 is rotated, and the second hanging wheel 60 is caught by the vanes 61 (see FIG. 6). The two wires 2 rotate in an endless track by the rotational force of the second driving wheel 60. As the second wire 2 rotates, the angle of the vertical is gradually opened perpendicular to the window.

On the other hand, when the vertical wire is completely opened or caught in the middle while the second wire 2 is rotating, the tension of the second switch operating wheel 73 is applied from the second wire 2 as in the operation of the first wire 1. 7 moves upwards or downwards based on the drawings, and as shown in FIG. 7, the second switch operating lever 75 moves along the guide hole 76a by the movement of the second switch operating wheel 73. The two-switch operation piece 76 is moved, and any one of the limit switches S3 and S4 is turned on by the second switch operation piece 76, and the control unit stops the driving motor 11, and the third solenoid By (16), the second movable plate 13a is returned to its original position. Immediately after the drive motor 11 is stopped, the drive gear 11c is rotated in the opposite direction by a predetermined section so that the third power transfer gear 15 engaged with the drive gear 11c and the second drive wheel 60 is engaged. The third power transmission gear 15 is removed by rotating in reverse.

When the remote control is operated to close the vertically open window substantially horizontally with respect to the window, as shown in FIG. 9, the control unit changes the rotational direction of the driving motor 11 and is driven by the fourth solenoid 16a. The fourth power transmission gear 15a is engaged with the driving gear 11c and the second driving wheel 60. The vertical wire is closed while the second wire 2 is moved by the second driving wheel 60.

When the vertical is closed horizontally or caught in the middle of the window, the driving of the drive motor 11 is stopped and this operation is the same as described above, and thus will be omitted.

10a and 10b respectively show the installation state of the automatic curtain driving apparatus according to the present invention, as shown in Figure 10, the driving device 100 according to the present invention is the guide frame (F) of the curtain (C) It can be installed in the, if the installation space can not be installed next to the guide frame (F) as shown in Figure 10b, each wire (1) (2) flexible hoses 80, 81 Inserted into the inside, can be installed in the free space driving device 100 according to the present invention.

Therefore, the tension applied to the wires (1) and (2) determines the complete opening / closing of the curtains, so that interference does not occur when the curtains move, and the size of these components does not change with the change in the size of the curtains. .

In addition, the frictional force between the wire 1 and the driving wheel 20 or 60 for rotating the wire 1 is increased to prevent the phenomenon in which the wire 1 does not rotate and slips when the driving wheel 20 or 60 is rotated.

In addition, there is no unnecessary operation for converting the driving of the curtain from electric to manual.

As described above, in the automatic curtain driving device according to the present invention, the curtain is fully opened and closed by the tension of the wire, and the operation of the device is controlled by controlling the operation of the device, thereby increasing the accuracy of the operation, regardless of the size of the curtain. Can be shared

In addition, since the frictional force between the wire and the driving wheel to which the wire is wound increases, the wire is normally rotated when the driving wheel rotates, thereby improving reliability of the product.

In addition, there is an effect such that the manual / automatic is switched without a separate operation, the manual / automatic switching operation is convenient.
