Changhong Meiling Has Been Granted An Invention Patent Authorization: A Damping Monitoring Device For Washing Machine Shock Absorbers And Washing Machine Shock Absorbers

According to data from Qichacha, Changhong Meiling (000521) has obtained a new invention patent authorization, titled "A Damping Monitoring Device for Washing Machine Shock Absorbers and Washing Machine Shock Absorbers". The patent application number is CN202210877722. X, and the authorization date is July 9, 2024.
Patent Abstract: This application provides a damping monitoring device for a washing machine shock absorber and a washing machine shock absorber. By setting a pressure sensor at the contact point between the damping rod and the damping cylinder of the shock absorber, the pressure sensor provides real-time feedback on the stress magnitude between the damping rod and the damping cylinder during each vibration. The magnitude of stress is used to reflect the vibration situation, and the magnitude of stress is converted into electrical signals through pressure sensors, thereby achieving the reflection of vibration quantity through electrical signals. Then, the controller compares the vibration reflected by the electrical signal with the vibration threshold range to determine the damping performance of the shock absorber in real time, and releases the oil used to increase or decrease damping based on the state of the damping performance. In the presence of multiple shock absorbers, the controller also monitors the vibration situation of multiple shock absorbers in real time and adjusts the consistency of the damping performance of the shock absorbers based on the detection signal feedback from the pressure sensor.
