Motor-driven curtain or blind assembly

摘要

Systems and methods for a motor-driven curtain or blind assembly are provided. For example, in some embodiments the motor drive assembly includes a track, a lead runner, and a plurality of sensors. The track can have a plurality of coils that can be electrically activated to generate an electromagnetic field to cause the lead runner to slide along the track. The lead runner may include magnet housing with a magnet to interact with the electromagnetic field. In some embodiments, the plurality of sensors or switches can be disposed between the coils. The sensors can be configured to activate the electromagnetic field locally to cause the lead runner to slide along the track. Examples of the sensors or switches include, but are not limited to, a reed switch, a silicone magnetic switch, an optical switch, a mechanical limit switch, a proximity switch, a magnetic encoder, or an optical encoder.

主权项

1. A curtain or blind assembly comprising:
a track having a plurality of coils fixed along the track, wherein the plurality of coils can be electrically activated to generate an electromagnetic field, wherein the track includes an iron strip to increase the electromagnetic field, and a carrier which provides electrical insulation and is interposed between the iron strip and the plurality of coils, and wherein the plurality of coils are placed in pairs along the track and configured to be electrically connected to different polarities to create alternating north and south poles; a lead runner with a magnet housing which houses a permanent magnet, the lead runner configured to slide along the track in response to an activation of the electromagnetic field triggered by an application that executes on a mobile device; and a plurality of sensors and switches disposed between the plurality of coils, wherein during operation, when the permanent magnet is disposed directly under a subset of the plurality of coils, a magnetic field of the permanent magnet is configured to cause contact closure in a subset of the plurality of switches corresponding to the subset of plurality of coils to allow electrical power flow exclusively to the subset of the plurality of coils to activate the electromagnetic field therein to cause the lead runner slide along the track, while a remaining of the plurality of coils do not receive electrical power.
