Description

Technical Field

[0002] As people's living standards continue to improve, the demand for smart electronic products is also growing, especially in the field of smart homes. The emergence of smart curtains has greatly facilitated people's home life. They can be controlled by remote control, voice control, mobile phone APP control, remote control, timer control of curtain opening and closing, and other functions. Not only does it facilitate people's daily home life, but it also improves the overall home decoration level.

[0003] The core component of an electric curtain track is the curtain motor, which drives the curtains automatically on the track. However, existing motor assemblies on the market are too large. After installation, the motor is exposed outside the curtain, which is very unsightly, affecting the aesthetics and lowering the quality of home decoration. Because the electric curtain motors commonly used on the market are outdated and have long passed the protection period, they are still produced by various manufacturers. As a result, the compatibility between the motor and the track transmission box is poor, and the failure rate is high. In addition, when encountering inward-opening windows, the window cannot be opened due to the oversized motor. In addition, the existing improved small motor assemblies for electric tracks on the market have complex internal structures, low production efficiency and high production costs, and cannot be truly reduced in size, which cannot solve the above problems.
