Description

The present invention relates to the field of electric curtains, and specifically to smart electric curtains.

With the development of society and the improvement of people's lives, the demand for smart curtains is also increasing, and people install curtains to adjust the brightness of the room in office areas, living areas, and learning areas. Since conventional curtains are basically operated manually, the operation is troublesome and time-consuming. Recently, many electric curtains that are driven by a motor and open and close automatically have been released, which saves time and effort and is easy to operate. However, as the control requirements for curtains increase, more electronic components are added inside to achieve more intelligent control, resulting in larger volume of drive housing and more space. Will come to do.

Also, during installation, the motor must be placed coaxially with the rope reel, the transmission of the motor drives the coaxial rope reel to rotate synchronously, and the motor is typically at the end of the upper beam or in the middle of the upper beam. A position-mounted, end-mounted motor drives the rotation of the rope reel via a single output shaft, and the intermediate-mounted motor drives the rotation of the rope reel via a dual output shaft. Drive. Currently, there are two types of mainstream electric blind / beehive curtain motors on the market: single output and double output. The coaxial arrangement of the motor and the rope reel cannot be applied to short curtains, which limits the spread of electric curtains. At the same time, motor rotation and assembly requires the combination of different parts, which is complex and costly.

Also, as a problem common to conventional blinds / beehive shades, the internal mounting space of the upper beam is small, so the motor mounted inside the upper beam becomes very small, and the power supply that supplies power to the motor is also external. It has to be installed separately at the end of the upper beam or to the outside with a wired connection, which is very unattractive and has safety problems.

With respect to the current state of the prior art as described above, the technical problem to be solved by the present invention does not occupy a large space, can guarantee the external aesthetics, and can be used by users of intelligent control over the electric curtain. It is to provide smart electric curtains that can handle curtains of various sizes and lengths while meeting the demands.
