[0002] In the field of modern building and home automation, push rod devices are key components for the automatic opening and closing of windows, and their performance and reliability directly affect the user experience and safety. Traditional push rod devices often suffer from problems such as insufficient control precision, poor synchronization, complex structure, and fragility, especially in situations requiring precise control of window opening angles or simultaneous opening of multiple windows.
[0003] Specifically, the control units of traditional push rod devices often use mechanical or simple electronic switches, making it difficult to achieve complex control logic and precise position feedback. This results in less smooth window opening action and makes it difficult to adjust the opening speed or stopping position according to actual needs. In addition, the transmission components of traditional push rod devices are often not optimized, resulting in low transmission efficiency, high noise, and easy wear, which affects the service life and reliability of the push rod device.
[0004] While some improved actuators have emerged in the market to address the aforementioned issues, most have yet to fully resolve the technical challenges related to control precision, synchronization, and durability. For instance, although some products utilize motor drives, the design of their transmission mechanisms remains crude, failing to effectively reduce friction and wear during transmission. Furthermore, the control units exhibit relatively limited functionality, lacking intelligent control strategies and real-time feedback mechanisms. Utility Model Content
