In summary of the above technical features, the main effects of the shift control structure of the present electric roller shutter can be clearly shown in the following embodiments.

Referring to the first figure, the shift control structure of the electric rolling door and window of the embodiment is used for controlling a motor (A1) of an electric rolling door and window (A) for winding or winding the electric motor. Rolling door and window (A), the shift control structure of the electric rolling door and window includes:

An encoder (1) is electrically connected to the motor (A1) to detect the actual amount of rotation of one of the motors (A1). A storage unit (2) stores a preset first rotation amount and a preset second rotation amount greater than the first rotation amount. A comparison module (3), the signal is connected to the encoder (1) and the storage unit (2). A shifting unit (4), for example, a transformer, or a circuit for varying the magnitude of the current entering the motor (A1), the signal is coupled to the comparison module (3) and the motor (A1).

For example, it is also possible to retract the electric roll door (A) for opening. First, the motor (A1) starts with a first rotational speed and winds up the electric rolling door window (A). The first rotational speed is relatively slow, so as to avoid excessive torque of the motor (A1) initial starting, such as gears and transmissions. Risk of damage to parts such as shafts and chains. The encoder (1) detects the actual amount of rotation of the motor (A1) during the winding of the motor (A1) at the first rotational speed of the motor (A1), and the comparison module ( 3) comparing the actual amount of rotation and the first amount of rotation stored by the storage unit (2), when the actual amount of rotation matches the first amount of rotation, the comparison module (3) generates a A variable speed signal.

The actual amount of rotation and the second amount of rotation stored by the storage unit (2), when the actual amount of rotation matches the second amount of rotation, the comparison module (3) generates a second shifting signal. After receiving the second shift signal, the shifting unit (4) changes the motor (A1) from the second rotational speed to a third rotational speed between the first rotational speed and the second rotational speed. When the motor (A1) is shifted to the third rotational speed, the end of the electric rolling door window (A) is located at a lowering speed position (C), and when the electric rolling door window (A) is completely closed, the electric rolling door and window (A) The end of the ) is located at a closed position (D) (e.g., the ground). Preferably, the reduced position (C) is between 60 and 100 cm from the closed position (D), and this embodiment is 80 cm. By the way, the motor (A1) winds the electric winding door window (A) to a relatively slow third speed to stop, avoiding excessive torque generated by the motor (A1) when the speed is fast and instantaneously stopped, such as Risk of damage to parts such as gears, drive shafts, and chains. The electric roller shutter (A) is shifted to a relatively slow third speed 80 cm away from the closed position (D) to ensure safety such as a person or a pet.

Referring to the first and fifth figures, the resistance sensing unit (5) of the embodiment generates an abnormal resistance signal when sensing the abnormal resistance when the motor (A1) rotates, and the shifting unit (4) After the abnormal resistance signal is received, the motor (A1) is stopped, and the motor (A1) is reversed by a preset reverse rotation amount, and then stopped, so that the electric winding door window (A) is scrolling. When it collides with an object, such as a person or a pet (E), it can be reversely scrolled by a predetermined amount and then stopped to ensure the safety of the person or pet (E) or the like. In addition, the infrared sensing unit (6) of the embodiment generates the shielding signal after sensing the shielding object on the opening path or the closing path of the electric rolling door window (A), such as a person or a pet (E). After that, the shifting unit (4) receives the shielding signal to stop the motor (A1), and stops the motor (A1) by reversing the preset reverse rotation amount, and then stops the electric winding door (A). The predetermined amount can be reversely scrolled and then stopped to ensure the safety of the person or pet (E) or the like.
