Description

Electronic clutch control electric blinds {ELECTROMAGNETIC CLUTCH-CONTROLLED ELECTRIC BLIND}

TECHNICAL FIELD The present invention relates to blinds and, more particularly, to an electromagnetic clutch-controlled electric blind.

Typical electric blinds generally have an upper frame, a lower frame, a plurality of blind flesh positioned between the upper frame and the lower frame, a gap adjusting device capable of raising, lowering, lowering the position of the lower frame, and changing the area occupied by the blind. It includes a tilt control device that can adjust the angle to change the amount of light entering the blind. Among them, the spacing device usually includes a pull string exposed on the side of the blind to allow the user to raise or lower the lower frame by pulling the string. On the other hand, the tilt adjusting device also includes a tilt adjusting part exposed on the side of the blind so that the user can change the tilt angle of the blind flesh. However, the exposed pull line of the conventional blind described above can be adjusted only after approaching the blind with a human hand, which inconveniences the user and wastes effort. On the other hand, the exposed pull lines of the blinds are also unfamiliar with children's playing or handling at any time, thus providing an unfortunate example of breakdowns and entanglements, so that the exposed pull lines are clearly the most dangerous of the residential environment. To make a factor.

Therefore, many contractors have devoted themselves to the study of blinds and motorized blinds where no pulling lines are exposed. As for the existing general electric blinds, as shown in US Patent No. 5,103,888, the motor must be installed in the upper frame or the lower frame, and the operation by the remote control is controlled to control the rise and fall of the blind pull line. However, the operation of this motor can only be used for raising and lowering the blind flesh, and there is no way to adjust the tilt of the blind flesh, so when the user tries to adjust the tilt of the blind flesh, he also goes near the blind and adjusts it with human hands. Must be used This lacks convenience in user operation.

It is therefore a main object of the present invention to provide an electronic clutch controlled electric blind. The electric clutch control electric blinds can not only electrically adjust the width of the blind flesh up and down, but also can adjust the tilt angle of the blind flesh electrically, thus providing convenience of automation and operation in the blind adjustment operation.

Another object of the present invention is to provide an electric clutch control electric blind, which requires a single power transmission power source and which can reduce the cost by making the size of the entire mechanism relatively small.

In addition, the electronic clutch-controlled electric blind provided by the present invention is a kind of electronic clutch-controlled electric blind, which includes an upper frame and a pair of blind flesh, and the upper frame forms an accommodation space therein, and a pair of blind flesh is slightly blind flesh. A blind transmission structure comprising: a power transmission mechanism including an electronic clutch that is always connected to or disconnected from the motor, and used to raise or lower the height position of each blind flesh when its main shaft indicates a state in which the motor is connected. A spacing adjustment sensor portion, the inclination adjustment sensor portion which can be used to change the inclination angle of each blind flesh when its main shaft is connected to the motor through the electronic clutch and indicates the state in which the electronic clutch and the motor are connected.

In FIG. 9, the tilt adjustment sensor unit 60 is used to measure the horizontal position and the limit of the left and right tilt of the blind flesh tilt. It mainly includes a tilt detecting disk 61, a fixed plate 62, and a tilt sensor 63.

The tilt detecting disk 61 is fixed to one end of the tilt adjusting shaft 42 of the tilt adjusting unit 40 and rotates under the operation of the tilt adjusting shaft 42. The left limit sensor 611, the horizontal sensor 613, and the right limit sensor 612 are respectively provided at predetermined positions outside the tilt detection disk 61.

When both shaft motors 21 transmit power to the tilt adjustment shaft 42 to rotate, at the same time power is also transmitted to the tilt detection disk 61 to rotate together, and when the blind flesh 121 is tilted to the left as far as possible to the left The limit sensor 611 directly reacts with the left limit sensing unit 631, and transmits this reaction signal to the two-axis motor 21, so that the two-axis motor 21 can stop the operation at any time. When the blind flesh 121 is inclined as far as possible to the right, the right limit sensor 612 immediately reacts with the right limit detection unit 632 to transmit the reaction signal to the biaxial motor 21, and the biaxial motor 21 Allow it to stop working again at any time.

So far, the structure of each part of the motorized blind structure 100 which electronically adjusts the space | interval and the inclination and the component construction method were demonstrated. The following is how it works.

To reduce the width of the blind flesh: When the transmitter 24 of the power transmission mechanism 20 transmits a signal to reduce the gap through a human hand, the receiver 25 immediately receives this signal and transmits it to the two-axis motor 21, and the gap adjusting sensor The electronic clutch 22 connected to the unit 30 is brought into an engaged state and is operated in connection with the biaxial motor 21. The other side of the electronic clutch 23 is to be separated from the tilt control sensor unit 4, it can be connected to the two-axis motor 21 to operate. At this time, the power of both shaft motor 21 is directly transmitted to the winding shaft 31 of the gap adjusting unit 30, the winding shaft 31 is rotated by transmitting a movement to each winding disk 33, and is connected At the same time as the spacing pulley 34 is wound up, it is first wound on the conical surface 332 and then gradually wound onto the winding surface 332 again. The lower frame 123 may be pulled up by winding the gap adjusting pull line 34, and at the same time, the blind flesh 121 may be raised from the lower frame 123 in order to raise the position of the blind flesh 121. When the blind flesh 121 is collected to the limit position (collected to the narrowest state) through the operation of the gap detecting unit 50, the biaxial motor 21 stops the operation and the structural parts are adjusted. To prevent damage.

When adjusting the width of the blind flesh, When the transmitter 24 of the power transmission mechanism 20 transmits a signal for widening the interval through the hand of a person, the operation manner thereof is approximately the same as the state when the width is narrowed. However, as the two-axis motor 21 rotates in the opposite direction (a direction opposite to the rotational direction when the width is narrowed), and the gap adjusting pull string 34 is released from the winding disk 33, The effect is to widen the gap. At the same time, when the blind flesh 121 reaches the limit position (the state where the blind flesh is opened at the widest interval), the two-axis motor 21 operates likewise through the operation of the gap detecting unit 50 (see FIGS. 6 and 7). Stops and prevents damage to structural components.

In the method of adjusting the inclination of the blind flesh, the operating method of adjusting the inclination angle of the blind flesh 121 is as follows.

When the human hand sends a signal to the transmitter 24 of the power transmission mechanism 20 to increase the inclination angle, the receiver 25 receives the signal, transmits the signal to the biaxial motor 21, and adjusts the spacing adjuster ( When the electronic clutch 22 connected to the 30 is removed, the two-axis motor 21 cannot move. On the other hand, the other side of the electronic clutch 23 is connected to each inclination control unit 40, and is connected to the two-axis motor 21 to operate. At this time, the power of the two-axis motor 21 is transmitted to the set of teeth 41 of the gap adjusting unit 40, the tilt adjusting shaft 42 is rotated due to the gear 41, and at the same time the tilt adjusting disk 43 Is reversed to change the direction, both ends of the fixed tilt adjustment pull line 44 due to the tilt adjustment disk 43 is moved up and down, respectively, and changes the inclination angle of each blind flesh (121) To achieve the function of increasing the inclination angle of the blind flesh 121. At the same time, the left limit sensor 611 or the right limit sensor 612 immediately responds when the blind flesh 121 is inclined to the limit position from side to side through the action of the tilt adjustment sensor unit 60, thereby causing the two-axis motor 21 to act. Stop operation and prevent unnecessary operation and damage.

On the other hand, specifically to this, when the interval between the blind flesh 121 is narrowed or widened, the receiver 25 is first connected to the electronic clutch 23 connected to the interval adjustment sensor unit 40, blind The electronic clutch causes the flesh 121 to automatically return to the horizontal position first (the horizontal sensor 613 and the horizontal sensing unit 633 interact with each other to stop the operation of the two-axis motor after the mutual response). The 23 is removed and connected to the electronic clutch 22 to adjust the operation of the blind flesh 121.

The above description so far, as shown in FIG. 10 of the present invention, the two-axis motor 21 is the gap adjusting portion 30 and the tilt adjusting portion 40 toward the electromagnetic clutch 22, 23 in different directions. It is connected to), and transmits power to the spacing control unit 30 and the tilt control unit 40 as a single power source. FIG. 11 illustrates a second embodiment of the present invention, which is different from the above-described embodiment because the two-shaft motor 21 is directly connected to the gap adjusting unit 30. ) Is separated, and when the blind inclination is added, the electronic clutch 23 is connected to the inclination control unit 40 to provide power so that the space adjustment unit 30 can operate to a slight degree, but the inclination control unit ( Since the rotation range of 40) is only a small range, the range in which the gap adjuster 30 moves together is small, and only causes the lower frame to make small up and down operations, and does not affect the reliability of the operation. 12 shows a third embodiment of the present invention, which differs from the first embodiment in that the motor 21 'is a single-axis motor, and a pair of gears is operated by such a single-axis motor, 41 operate the electromagnetic clutches 22 and 23 and the space | interval / tilt adjustment part 30 and 40, respectively. Fig. 13 is in accordance with the fourth embodiment of the present invention, which is different from the third embodiment in that the single-axis motor 21 'is directly connected to the gap adjusting unit via a set of teeth 41. FIG. 14 shows a fifth embodiment of the present invention, in which the single-axis motor 21 'is directly connected to the gap adjusting unit 30, and again connected to a set of teeth 41, and then again an electronic clutch of another shaft. 23 and the tilt control unit 40 is connected.

The present invention, that is, the structure of each part of the electric blind structure 100 for electronically adjusting the width and inclination, its component configuration method, the operation method have been described in detail.

First, both the rise and fall height of the blind flesh and the angle of inclination of the blind flesh have the ability to adjust both. Since the adjustment of the adjustment part for adjusting the blind flesh up and down or the adjustment part for adjusting the inclination angle of the blind flesh is solely separated and combined through the electronic clutch, all of the power of the motor is transmitted and the effect of the electric control is achieved. The defects that made simple electric adjustments such as the adjustment of the blinds up and down are eliminated only if the user is familiar with the operating technology.

Second, the source of power is single, the mechanism is relatively small and sophisticated. Effective use of the separation and coupling effects of the electronic clutches during gap adjustment and tilt adjustment allows a single power source to power two loads, and is relatively inexpensive, has a sophisticated structure and significantly reduces the space consumption of the blind upper frame. Decrease.

Third, reduce the probability of damage to the instrument. Since the space | interval adjustment part and the inclination adjustment part are provided in this invention, it can use when the blind flesh rises and falls to a limit position, respectively, or changes the inclination angle. The two-axis motors can be stopped immediately, reducing unnecessary consumption and waste of power in the device and increasing the service life of the device.
