  • a conventional shutter generally includes a frame 20 pivotally disposed on the edge of the window (not shown) and a plurality of blades 21a pivotally disposed on two sides of the frame 20 in horizontal parallel. Two ends of each of the blades 21a are inserted into the pivot holes (not shown) on the inner side of the frame 20 through a pivot piece 210 which can be rotated and has an appropriate damping (used for preventing the bladeset from rotating automatically due to its own weight).
  • the intermediate section of each of the blades 21a facing the room is linked up with each other through a pull rod 22 via looped links, such that the angle of the whole bladeset 21 of the shutter is adjusted by pushing and pulling the pull rod 22 manually.
  • the operation may be motorized by using a motor device.
  • a motorized mechanism must be in capable of being operated forward and backward, and generally a small DC motor can be used and a cell is used as a power.
  • angle control it is substantially possible that multiple shutters are operated simultaneously by using a remote control signal, however, if starting forward and backward rotations and stopping are controlled only depending on visualization by an operator, one similar case that multiple shutters are incapable of being simultaneously adjusted to a common given angle during an manual operation still occurs.
  • the motorized device a user can still operate manually, thus a motorization design must meet such a requirement and should not result in a conflict or damage to the device. Therefore, the present invention is to achieve the convenience in use and operation and to achieve a motorization of the bladeset angle of the shutter by using simple and reliable device and method.
  • the present invention provides a method to motorize bladeset rotation angle of a shutter, which allows the user to operate by taking a given target angle as an instruction.
  • the method comprises resetting the bladeset of the shutter to an origin point position at first when an instruction of starting the target angle is received; and then rotating the bladeset of the shutter to a given target angle with respect to the origin point, and calculating a residual angle deviation to continuously rotate the bladeset to the given target angle when an instruction of the given rotation angle is received again during the operation.
  • a preferred embodiment of the present invention provides five kinds of instruction selections such as an upper origin point, 45 degrees, 90 degrees, 135 degrees and a lower origin point, such that the bladeset of the shutter automatically rotates to the required rotation angle only according to one instruction from the user.

  • a moment restrictor is also provided in an embodiment of the present invention, such that only appropriate connecting moment is delivered between the driver and the bladeset, thus when the moment exceeds a preset range, the moment restrictor is departed from each other, thereby protecting the drive construction from being damaged and allowing the user to adjust the bladeset manually.
  • the method and device to motorize bladeset rotation angle of the shutter according to the present invention enables the bladeset of the shutter to be rotated to the given angle under an instruction, and allows a remote control operation, and meanwhile controls the bladeset of multiple shutters to be rotated to the target angle. Furthermore, the present invention enables the bladeset of the shutter to seek the origin point wisely, controls the rotation to the target angle accordingly, and allows updating of the requirement for the target angle during the process, thereby saving the time and power consumption and considering both the motorized and manual operations.
  • the device 1 to motorize bladeset rotation angle of shutter of the present invention comprises a body 10 buried on one side of a frame 20 of the shutter, an output shaft 109 fitted with one end of one of the blades of the bladeset 21 through an end cover 212 for transmission.
  • the body 10 can be controlled remotely with an input interface 61 by transmitting signals in a wired or wireless manner, and the wireless communication manner may be a radio frequency or an infrared signal manner.

  • the sensor 40 includes an actuating piece 41 connected to the output shaft 109 and a switch 42
  • the driver 50 includes a motor 51 and a reduction gear set (such as the gears 52, 53, 54, 55 described below), for driving the output shaft 109.
  • the controller receives the instruction signal from the input interface, the driver 50 is controlled to determine the origin point position of the bladeset 21 by utilizing the sensor 40, and then the bladeset 21 is further driven to the target angle.
  • FIG. 5 shows a local structure of one embodiment of the driver 50, the sensor 40, and the bladeset 21 (represented by the end cover 212).
  • the output shaft of the motor 51 is connected to a motor gear 52, a big gear 53 is engaged with the motor gear 52, a small gear 54 and the big gear 53 are set coaxially, which are connected with each other or have a moment restrictor, an output gear 55 is fixed to the output shaft 109, and the above motor 51, motor gear 52, and coaxial gear set (including the big gear 53 and the small gear 54) and output shaft 109 together form the driver 50 disposed in the body 10, such that the coaxial gear set (including the big gear 53 and the small gear 54) and the output shaft 109 may be positioned and rotated pivotally, and thereby the rotary force of the motor 51 is decreased in speed and increased in force and then transmitted to the output shaft 109.
  • the output shaft 109 forms a cross shaped (or another suitable shape) spindle hole 109a to transfer the rotary force in combination with a protrusion 212a corresponding to the end cover 212 of the blade.
  • the motor 51 preferably is a stepping motor, by the driving pulse of which the rotation angle is controlled exactly.
  • At least one actuating point is set on the output shaft 109, and here two actuating protrusions 411, 412 respectively correspond to the upper origin point U and lower origin point D of the bladeset 21.
  • the actuating protrusions 411, 412 press a switch 42 for an actuation through a spring 413, such that the switch 42 produces an ON signal when the output shaft 109 and the bladeset 21 are rotated to near the positions of upper, lower limits of a rotatable range of the blade (that is the upper origin point and the lower origin point), while produces an OFF signal when they are at other intermediate angles.
  • the controller (not shown) controls the bladeset 21 to be rotated and positioned according to the signals, and once the controller determines that the bladeset 21 has reached the upper or lower origin point U or D, the blades are accordingly controlled to be rotated to other positioning angles A, B, C etc.
  • the above spring 413 and switch 42 (fixed on a circuit board 62) are both fixed within the body 10, and form the sensor 40 together with the actuating protrusions 411, 412.
  • FIG. 6 shows an embodiment of the input interface 61 of the present invention.
  • the input interface preferably is a remote control, such that multiple shutters may be remotely controlled simultaneously with a radio frequency or an infrared signal.
  • the input interface 61 is provided with a plurality of given target angle keys, for example the upper origin point key 610, the first target angle key 611, the second target angle key 612, the third target angle key 613, the lower origin key 614 and a stop key 615. Accordingly, the user only needs to choose to press any one of the target angle keys 610, 611, 612, 613, and 614 to send out the instruction signal, the device of the present invention automatically performs the angle control. During the performance, the user may change the target angle at any time or may press the stop key 615 to stop the rotation of the bladeset 21.
  • FIG. 7 is a schematic view of the rotation angle of the bladeset 21.
  • the blade when starting from an initial point S1, the blade first rotates upwards until reaching the upper origin point U (the sensor is ON), and then the controller counts the angle (with time or in pulse number) inversely to rotate the blade to the target angle T1. During this period, for example being at the intermediate point M1 before reaching the upper origin point U, even though the setting of the target angle is changed, the controller continues to perform an upward rotation to turn to the control of a new target angle after finding the upper origin point U (if the target angle is the upper origin point U or the lower origin point D, the rotation proceeds upwards, downwards to the end at any time).
  • the controller reckons a subsequent travel with the current position and continues to rotate the blade to the new target angle T2. For example, if again receiving the instruction of a new target angle at an intermediate point M3 before T2 is reached, the controller inversely rotates the blade to the new target angle T3 since the position has been exceeded.
  • the blade 21 originally stops at the lower origin point D, the sensor being ON, and when being restarted, the controller is incapable of determining whether the blade 21 is at the upper origin point U or at the lower origin point D (since the blade may be moved manually by the user when it is stopped), so the controller still controls the blade to rotate upwards.
  • the sensor 40 is checked at real time, and if it is found that the signal has changed from ON to OFF, it is known that the blade 21 is at the lower origin point D originally, and the blade can be controlled to rotate towards the target angle (that is the second target angle B) accordingly.
  • FIG. 8 is a flow diagram.
  • the state of sensor in a current position is checked and recorded (step S 10).
  • the blade rotates upwards by a certain rotation angle (step S20).
  • the case on a change in the sensor is determined (step S30). If the sensor 40 changes from ON to OFF, it represents that the blade originally is at the lower origin point, so a present angle equals to the lower origin point minus the rotation angle (step S40), the rotation continues to be controlled accordingly.
  • the controller may continues to rotate the blade by a certain rotation angle for a re-determination, and when it is determined that the sensor remains ON, it represents that the blade now is at the upper origin point, and a present angle equals to the upper origin point (step S50), and the blade may be rotated downwards to the target angle accordingly.
  • a difference between an up-to-date target angle and a present angel is viewed circularly (step S60).
  • the blade is rotated upwards, that is the blade is rotated upwards by a rotation angle and the rotation angle is subtracted from the present angle (step S70). If the present angle is less than the target angle, the blade continues to be rotated downwards, that is the blade is rotated downwards by a rotation angle and the rotation angle is subtracted from the present angle (step S80). If the difference equals to 0, the rotation is stopped.
  • the rotation angle modified each time is represented by 5 degrees, and practically other angle values may also be used for operation.
  • the motor functions as a power which is slowed down by the reduction gear set, such that the output shaft generates a sufficient moment, correspondingly, when the pull rod or blade is rotated by manual operation, or a barrier is encountered or a dead point is reached during the blade rotation, an external force is input from the blade, which relatively drives an internal driver means to rotate instantly and rapidly, such that the driver means is easy to be damaged. Therefore, in the present invention, a moment restrictor is designed on the transmitting path between the transmitting shaft and the motor output shaft, such that the transmitting force detaches when the external force or load exceeds a preset value, and thereby avoiding the driver means from being damaged by the external force. In the embodiment as shown in FIG.
  • an elastic damping structure is designed on the coaxial reduction gear, and as shown the perspective and exploded view of FIGs. 9a and 9b, the big, small gears 53, 54 are slidably arranged on the shaft rod 56, and an elastic piece, for example colloidal silica or a rubber ring 59, is clamped therebetween, which is firmly locked to an appropriate pressure by utilizing the shoulder region of one end of the shaft rod 56 or a snap ring 561 as well as a screw thread 562, a washer 580 and dual lug nuts 581, 582 at the other end, and thereby generating an appropriate friction rotation moment.
  • an elastic piece for example colloidal silica or a rubber ring 59
  • a moment is set sufficient to be output from the inside to drive the blade to rotate, and is capable of protecting the internal driver means from being damaged by the undue moment input from the outside via an overload slip.
  • the moment restrictor naturally may be designed between the output gear and the output shaft, or on the motor gear.
  • the method and device to motorize bladeset rotation angle of the shutter of the present invention at least can achieve the following functions.
