AI Technical Summary
Technical Problem
Existing active suspension systems have batteries that consume a lot of power and require frequent charging, resulting in excessive energy consumption.
Method used
A combination of piezoelectric sensors and transformers is used. The transformer increases the current to supply the magnetic components to generate a magnetic field, which adjusts the suspension stiffness and damping. The controller calculates the required damping force, reducing the need for external power supply.
Benefits of technology
This achieves low power consumption of the suspension system, accurately suppresses vibration, extends the lifespan of the sensor, and reduces energy consumption.

Abstract
The utility model provides a kind of active suspension. The active suspension includes suspension body, transformer and controller, suspension body includes magnetic assembly and piezoelectric sensor, transformer is connected between piezoelectric sensor and magnetic assembly, and controller is connected with piezoelectric sensor and is connected with transformer. The active suspension of the utility model, when piezoelectric sensor generates current when suspension body is vibrated, part of current is supplied to magnetic assembly to generate magnetic field after increasing by transformer, so as to adjust the rigidity and damping of suspension body, another part of current is supplied to controller, and controller calculates the damping force required by suspension body and the current value required to reach the required damping force according to the received current, and adjusts transformer to make output current value consistent with required current value, so as to accurately suppress vibration. At the same time, since the current of magnetic assembly comes from piezoelectric sensor, the required external power supply of suspension body can be reduced or even no external power supply is needed, so the active suspension has lower power consumption.
