Definitions

  • the electric blind in the invention includes a frame, a plurality of slat units, a linking rod, and a stepping motor unit
  • the frame has two side vertical rods pivotally connected with the horizontal slat units between, and the linking rod is fixed with a lengthwise side of all the slat units, so all the slat units may synchronously swing to an angle by the function of the linking rod when the steering motor rotates one of the slat units,
  • the stepping motor is positioned in one of the two side vertical rods, connected with only one end of one slat unit so that all the slat units may swing at the same time by function of the linking rod.
  • a preferred embodiment of an electric blind in the present invention includes a frame 10, a plurality of slat units 20, a linking rod 30 and a stepping motor unit 40 as main components,
  • the frame 10 is provided with a plurality of insert holes 11 spaced apart equidistantly in two side vertical rods respectively, and a cavity 12 just behind one of the insert groove 11 in one of the two vertical rods.
  • the insert holes 11 in one side vertical rod are respectively at the same level with those 11 in the other side vertical rod to align to each other.
  • Each slat unit 20 as shown in Fig. 4 consists of a slat 21 and two end caps 22 with a recessed hollow 221 to fit around one of the two ends of the slat 21. Further, a pin 222 is fixed with in a center of an outer side of the end cap 22 to fit in the insert hole 11 of the side vertical rod of the frame so that each slat 21 may be combined pivotally and horizontally with the frame.
  • the connect rod 30 is fixed vertically with an lengthwise side of all the horizontal slats 21 so that all the slat units 20 may rotated for a certain angle at the same time by the interactive function of the connect rod 30, when they are driven by the stepping motor unit 40.
  • the stepping motor unit 40 consists of a stepping motor 41 and a controller 42, and the stepping motor 41 is positioned in the cavity 12 of the frame 10 and has a shaft 411, which is provided with a flat position surface 412 on its end. Further a linking member 43 fits around the flat position surface 412 of the shaft 411, having a position groove 431 and a fit groove 432 respectively in two ends. Then the shaft 411 of the stepping motor 41 fits in the position groove 431 of the linking member 43, and one of the slat unit 20 fits in the fit groove 432 of the linking member 43 so that the stepping motor unit 40 may drive all the slats units 20 through the connect rod 20 for changing the angle of the slat units 20. As to the controller 42, it is connected with the rear side of the motor 41, controlling the input pulse of the stepping motor 41 by means of infrared ray,
  • the electric blind has the slat units 20 possible to be handled to manually change the angle of the slat units 20, and also at the same time possible to be electrically handled to change the angle of the slat units 20.
  • the controller can control the input pulse to the stepping motor 41 so the shaft 411 of the stepping motor 41 may be rotated to a needed angle.
  • the electric blind is changed in its angle by the controller 42, which controls the input pulse to the stepping motor 41 and adjusts the rotating angle of the motor 41 so as to make the slat units 20 rotate for a needed angle.
  • the input pulse to the motor 41 might not force tire stepping motor 41 overloaded, enabling the slat units 20 still be swung for a needed angle whether the stepping motor 41 rotates or not, because the stepping motor 41 can rotate idle in the worst case.
  • the slat units 20 can have a movement to return to a zero point so the controller or manual operation can swing the slat units 20 to the zero point.
  • the stepping motor 41 can rotate idle if the slat units 20 is swung to the utmost point, and if the stepping motor 41 keeps on rotating for a preset time, the slat units 20 can be shut completely (i.e-, move to the zero point). And subsequently if the motor starts from the zero point, the slat units 20 are to be swung precisely to the needed angle according to the input pulse.
  • Fig. 6 shows a second preferred embodiment of an electric blind in the invention, which has the same structure as the first one, except that a gear unit is added between the motor 41 and the linking member 43.
  • the gear unit consists of a gear unit 433 and a set switch 44.
  • the gear unit 433 can be a bevel gear unit.
  • the set switch 44 is composed of a protruding wheel 441 and an electrical switch 442, and the protruding wheel can fit around the linking member 43 or firmly connected with the slat 21, the end cap 22 or the pin 222. Then when the slat 21 reaches the zero point, it touches the electrical switch 442, which then generates a signal, and the controller 42 receives the signal of the zero point from the slat unit 20.
  • the number of the combination of the protruding wheel 441 and the electrical switch 442 can be increased, augmenting the number of sensing points. For example, more accurate and timely control can be got by eight different locations that three sensing points in conjunction with a two digit code mode can obtain. It goes without saying that the sensing signal can be substituted by a photo-sensing mode, which is a well-known art not to be described here.
  • the invention has the following advantages, as can be seen from the foresa.id description.
  • the slat units can be manually rotated even if the stepping motor is still in operation, and then the stepping motor can rotates idle. Therefore, the angle of the slat units can be adjusted, not making any damage to the stepping motor, with its service life prolonged.
  • the control signal for the motor is pulse, so the rotating process for an angle of the slat units is in proportion to the number of the pulse. It means that the angle of the slat units can be accurately calculated by the number of the input pulse, so the stepping motor can make a preset angle rotation owing to the function of the controller, with its practicality and accuracy of the control increased.
