Frame Structure For Anti-Vibration Fan

Abstract

An anti-vibration fan includes a frame, a bottom chassis and an elastic frame. The elastic frame includes a plurality of curved plate-like suspending arms, each having a first suspending arm section. An end of the suspending arm section has a bent section with a curved shape at its middle section, and an end of the bent section has a second suspending arm section. The bottom chassis includes a disc body and a plurality of protruding ribs extended upward from the disc body and connected to the first suspending arm section. The second suspending arm section is connected to a frame body of the frame, and the plurality of suspending arms form the elastic frame. After vanes are pivotally connected to the bottom chassis, the elastic frame cancels out the vibration force produced by the rotating vanes, so as to reduce noises and enhance the life expectancy of vanes effectively.
