Description

CROSS-REFERENCE TO RELATED APPLICATION This patent application claims the benefit and priority of Chinese Patent Application No. 202411573103.7 filed with the China National Intellectual Property Administration on Nov. 6, 2024, the disclosure of which is incorporated by reference herein in its entirety as part of the present application. TECHNICAL FIELD The present disclosure relates to the field of mechanical engineering automation technology, and in particular to, a compact type dual-motor driving and force balance control device for roller blinds. BACKGROUND The existing electric actuator and reducer for window roller blinds are disposed externally, and generally employ a gear-screw speed-reduction mode. However, the conventional device not only has low speed-reduction efficiency, but also makes electric curtains unappealing due to its externally disposed motor and reduction gear. Moreover, the conventional device generally uses a single-motor and single-reducer driving mode, resulting in large size of the motor and reducer, which is not conducive to installation and maintenance. Thus, the conventional device is not conducive to meeting the requirements of making the electric roller blind system have simple and appealing appearance. Therefore, based on the above conventional problems, a compact type dual-motor driving and force balance control device for roller blinds is proposed. Motors and reducers are installed inside a roller blind spool, so that the electric roller blinds and a power system are integrated to the utmost extent, achieving the best compact effect for the electric roller blinds and the power system, and making the appearance of the system simple and appealing. SUMMARY The present disclosure is intended to provide a compact type dual-motor driving and force balance control device for roller blinds, for solving the problems as follows. The existing electric actuator and reducer for window roller blinds is disposed externally, and generally employs a gear-screw speed-reduction mode; however, the conventional device not only has low speed-reduction efficiency, but also makes electric curtains unappealing due to its externally disposed motor and reduction gear; moreover, the conventional device generally uses a single-motor and single-reducer driving mode, resulting in large size of the motor and reducer, which is not conducive to installation and maintenance; thus, the conventional device is not conducive to meeting the requirements of making the electric roller blind system have simple and appealing appearance. To achieve the objective described above, the present disclosure provides the following technical solutions. The technical solutions of the present disclosure are that a compact type dual-motor driving and force balance control device for roller blinds includes a roller blind spool; a left aluminum alloy support is fixedly disposed at one end of the roller blind spool, a left driving motor is fixedly disposed on one side of the left aluminum alloy support, a left driving output planetary reducer is fittingly disposed at an output end of the left driving motor, a left planetary reducer torque output shaft is fixedly disposed at one end of the left driving output planetary reducer, and a left connecting plate is fixedly disposed at one end of the left planetary reducer torque output shaft; and a right aluminum alloy support is fixedly disposed at an other end of the roller blind spool, a right driving motor is fixedly disposed at one end of the right aluminum alloy support, a right driving output planetary reducer is fittingly disposed at an output end of the right driving motor, a right planetary reducer torque output shaft is fixedly disposed at one end of the right driving output planetary reducer, and a right connecting plate is fixedly disposed at one end of the right planetary reducer torque output shaft.
