AI Technical Summary
Technical Problem
When the air conditioning unit damper is sealed, the lack of smooth contact between the housing and the damper or deformation can cause whistling and damper impact noise, affecting user comfort.
Method used
A soft rubber sleeve is fitted onto the damper plate, and equally spaced trapezoidal blocks are set on it. Hollowed-out parts and reinforcing ribs are set on the damper shaft. Combined with the sliding connection mechanism and the telescopic mechanism, whistling and impact noises are avoided.
Benefits of technology
The trapezoidal blocks guide and buffer the airflow, avoiding whistling and impact noises, improving user comfort, reducing the load on the damper drive mechanism, and facilitating maintenance and component replacement.
