Abstract
The invention discloses a stress buffer device and method for a rotary door. The stress buffer device comprises a connecting line, a multi-turn coil, two magnets, a charge pump system, an energy storage capacitor, a switch device and an electromagnetic rotary shaft damper. The connecting line is wound around a rotary shaft of the door, one end of the connecting line is fixed to the rotary shaft, and the other end of the connecting line is conducted with the induction coil. The induction coil is located between the two magnets arranged in parallel. The polarity of the opposite ends is opposite. A strong magnetic field is formed between the two magnets. The induction voltage is generated when the induction coil moves and cuts a magnetic induction line. The induction coil is connected with the input end of the charge pump system. Charge pump circuits are used for collecting the induction voltage generated by the induction coil and increasing the voltage. The output end of the charge pump system is connected with the energy storage capacitor in series. The energy storage capacitor supplies power to the electromagnetic rotary shaft damper through the switch device. When the electromagnetic rotary shaft damper is electrified, the resistance of the rotary shaft is increased under the effect of electromagnetic attraction. By the adoption of the stress buffer device and device for the rotary door, the resistance generated when the door is closed normally cannot be increased, and the damage of impact generated when the door is closed with strength to the door can be avoided effectively as well.
