the motor part is provided with opposed third and fourth ends; the third end of the motor part is in transmission connection with the transmission rod, and the fourth end of the motor part is exposed at the second end of the top rail to detachably connect the power supply part.
2 . The electric curtain of claim 1 , wherein a slide groove penetrating through both ends of the top rail along a length direction of the top rail disposed on an external surface of the top rail; a slide block slidably matched with the slide groove is disposed on a back surface of the power supply part.
3 . The electric curtain of claim 1 , wherein at least one clip for fitting onto the top rail is disposed on an external wall of the motor part, and a fitting opening matching the clip is disposed on a side wall of the top rail.
4 . The electric curtain of claim 1 , wherein the fourth end of the motor part is provided with at least one first magnet and/or first iron block, and an end of the power supply part for docking with the motor part is provided with a second magnetic block and/or second iron block for magnetically attracting the first magnetic block and/or first iron block.
5 . The electric curtain of claim 1 , wherein the drive device further comprises a control part, and the control part comprises a master control circuit board; the master control circuit board is disposed inside the power supply part; a power supply is disposed inside the power supply part, and the power supply is in electrical connection with the master control circuit board; an output interface is disposed in an exposed manner at a position close to the fourth end of the motor part on the master control circuit board; an input interface connected to the output interface is disposed in an exposed manner at the fourth end of the motor part.
6 . The electric curtain of claim 5 , wherein the motor part is internally provided with a motor core and a speed reducer; the motor core and the speed reducer are in transmission cooperation and fixedly connected; the speed reducer is close to the third end of the motor part, and the motor core is close to the fourth end of the motor part; an output end of the motor core is in transmission connection with an input end of the speed reducer, and an output end of the speed reducer is in transmission connection with the transmission rod; an end of the motor core away from the speed reducer is provided with a Hall plate and a signal magnet; a Hall sensor for sensing the signal magnet is disposed on the Hall plate; the fourth end of the motor part is internally provided with a transitional circuit board, and the transitional circuit board is in electrical connection with the Hall plate; the input interface is disposed on the transitional circuit board.
7 . The electric curtain of claim 6 , wherein a first vibration damping sleeve is connected at an end of the speed reducer away from the motor core, and a second vibration damping sleeve is disposed at an end of the motor core away from the speed reducer.
8 . The electric curtain of claim 7 , wherein a filling block is disposed at an end of the motor core away from the speed reducer in the motor part; the filling block is abutted against the second vibration damping sleeve to fill the gap between the motor core and the fourth end of the motor part.
