  • Patent number: 11936278
    Abstract: A fan braking structure includes a fan including a frame having an upright bearing cup, and a fan impeller having a vertical rotating shaft pivotally received in the bearing cup and provided at a free end with a groove; a braking structure located at a lower part of the bearing cup and including a brake plate and an electromagnet, and the brake plate being provided at one side with a protruded brake pin and at another side with a magnetic member; and an elastic element disposed between and pressed against the brake plate and the electromagnet. When the fan is powered off, the electromagnet is energized and produces magnetic poles that magnetically repel the magnetic member, such that the brake pin is pushed by a magnetic force and the elastic element toward the rotating shaft to engage with the groove, causing the fan to brake and stop rotating inertially.
