Description

Technical Field

[0001] The utility model belongs to the technical field of electric curtain equipment, and particularly relates to a side-by-side double-track curtain system. Background Art

[0002] As users have higher and higher requirements for the aesthetics of curtains, most of the existing curtain tracks use double tracks, and different styles of curtains can be selected according to user needs, which greatly improves the aesthetics of curtains. However, most of the existing double-track curtains use a single motor or are driven by double motors set at both ends of the track. The existing single-motor drive has a single driving mode for curtains and can only control the synchronous opening and closing of double-track curtains, which affects the user experience. In addition, the existing double motors are set at both ends of the track, which increases the overall area occupied by the curtains and affects the aesthetics.

[0003] In order to solve the shortcomings of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a smart curtain device with a single motor controlling a dual track [202120361813.9], which includes two curtain tracks arranged side by side and a dual-control transmission box assembly arranged at both ends of the two curtain tracks. A circle of synchronous belt is provided in each curtain track, and an end pulley for driving the end of the curtain is provided at the relative position of the two synchronous belts. The powertrain is composed of a clutch assembly, a motor assembly and a circuit board assembly arranged under the powertrain housing, which are arranged in sequence. The clutch assembly and the motor assembly are electrically connected to the circuit board assembly through a Hall sensor, respectively, and a pluggable power cord is connected to the bottom of the circuit board assembly.

[0004] The above solution solves the problem of the single motor driving curtains in existing curtains to a certain extent, but the solution still has many shortcomings. For example, its single motor cannot be used for larger curtains, and its applicability is low. In addition, its single motor needs to be adjusted when it is adjusted to a single curtain drive, which affects the user experience. Summary of the Invention
