However, after actual use, it is found that the electric curtain is operated at full speed no matter when it is opened or closed. Therefore, the controller will drive the drive motor to rotate at full speed, which is relatively large and relatively large in power loss. Causes a large electrical load, so the required specifications of the hardware are relatively large, and the relative manufacturing cost will be increased; in addition, when the full speed is started to the fixed point position, it is easy to cause over-rotation due to inertial force, causing the curtain The screen cannot be accurately adjusted to the desired position, which is not good for power windows that require precise control. Even when folded or unfolded to the frame, it will overturn and touch the frame due to inertia, causing noise. Need to improve.

Relative to the storage unit of the required operation stroke, a processing unit respectively connected to the storage unit, the rotational speed stroke detection unit, and the driving motor, and the aforementioned processing unit receives the driving command and compares it with the storage unit to obtain an operation stroke, and compares the The operation stroke is divided into different driving speeds, and the speed stroke detection unit can detect the execution position of the operation stroke, and provide the basis for the processing unit to determine and adjust the driving speed; therefore, when the electric curtain is operated, through After the speed stroke detection unit detects the operating position, it can set the operating stroke to low-speed drive in the front and back sections respectively, thereby reducing the electrical load at startup. It can also be positioned at a slow speed before closing, and when the drive motor outputs When the power does not reach the predetermined movement, the power will continue to increase to ensure that the power output by the motor can accurately drive the driving device to operate, avoid over-rotation displacement due to inertia, and ensure that the power window can be operated more accurately every time For positioning.

The aforementioned and other technical content, features and effects of the present invention will be clearly understood in the following detailed description of the preferred embodiment with reference to the drawings.

1, the first preferred embodiment of the electric curtain 3 with precise transmission of the present invention. The electric window 3 includes a frame 31, at least one shielding member 32 arranged on the frame 31, and a driving the shielding member 32 The actuating transmission device 33, and a driving device 34 that drives the transmission device 33 to act; wherein, the driving device 34 has a controller 341, and a driver 342 that is controlled to rotate by the controller 341 and drives the transmission device 33, The aforementioned controller 341 controls the driver 342 to output the required power.

Continuing the foregoing, the controller 341 includes a rotational speed stroke detecting unit 3411 that detects the rotational speed of the driver 342, a storage unit 3412 that stores a plurality of driving commands relative to the required stroke of the operation, and a storage unit 3412 connected to the rotational speed respectively The stroke detecting unit 3411, the processing unit 3413 of the driver 342; wherein the processing unit 3413 can input a driving command from the outside and compare it with the storage unit 3412 to obtain a running stroke, and divide the running stroke into different driving speeds In this embodiment, the processing unit 3413 drives the drive motor 342 to be at least divided into low-speed drive and full-speed drive, and the low-speed drive means that the drive motor 342 outputs about 20% of the driving force, so that the shielding member 32 is more Slow movement. As for the full-speed drive, the drive motor 34 outputs 100% of the driving force, so that the shielding member 32 can move quickly, so that the shielding member 32 can be moved on the operating stroke generated by the same command. The segments are divided into different moving speeds. Furthermore, in this embodiment, the driver 342 includes a drive motor 3421 controlled by the processing unit 3413, and a deceleration motor 3422 arranged between the transmission device 33 and the drive motor 3421 , And the aforementioned driving motor 3421 is controlled by the processing unit 3413 to control the driving speed.

Finally, when the deceleration motor 3422 is 41-50 laps, the processing unit 3413 drives the drive motor 3421 to drive at low speed or decelerate cycle by cycle. In addition, the The speed range detection unit 3411 can detect the number of revolutions of the deceleration motor 3422 to provide a basis for the processing unit 3413 to determine the operating position and adjust the driving speed; furthermore, when the drive 342 output power does not reach the predetermined movement , Will continue to increase power.

Referring to Figures 1 and 2, when this embodiment is in action, when the shielding member 32 is to be moved, when the controller 341 receives a driving command from an external input, the processing unit 3413 will compare with the storage unit 3412 , And then convert the drive command into an operating stroke, and after the processing unit 3413 segmented the operating stroke into different drive speeds, it drives the drive motor 3421 to run, so that the drive motor 3421 is linked to the deceleration motor 3422, and the deceleration The motor 3422 drives the shielding member 32 to move in conjunction with the transmission device 33, and then controls the drive motor 3421 to drive at a low speed during initial operation.
