Problems solved by technology

At present, researchers mainly use linear motors or "rotary motors + linear motion and rotary motion conversion devices (such as rack and pinion, ball screw, etc.)" to convert the mechanical energy of the relative motion of the suspension into electrical energy. The voltage changes randomly, and the voltage fed back by the motor is also an alternating current with a constantly changing amplitude, while most of the electrical equipment and energy storage devices on the vehicle are 48V DC, and the power supply needs to be relatively stable DC, so the amplitude of the motor feedback Changing alternating current is difficult to directly carry out effective recycling

Embodiment Construction

[0014] like figure 1 As shown, in the dotted line frame is the vehicle suspension system vibration energy recovery device of the present invention, which specifically includes: a linear motor, a rectifier module (i.e. the AC-DC module in the figure), a step-up and step-down circuit, a data acquisition circuit, a DC electromagnetic Relay switch and embedded host computer (that is, the embedded MCU in the figure).

[0015] The specific working principle is:

[0016] When the vehicle is running on an uneven road surface, relative motion occurs between the vehicle body and the wheels, which drives the linear motor in the suspension system to reciprocate and linearly move; (for the positional relationship, see figure 1 On the left side, the suspension system is a general term for the components connecting the car body and the wheels, mainly including springs and shock absorbers. )

[0017] The linear motor converts the vibration energy of the suspension system into three-phase a...

Abstract

The invention provides a vehicle suspension system vibration energy recovery device. Classical rectifier circuits and buck-boost circuits are taken as design basis, the voltage at the input end and the voltage at the output end are constantly collected, the error between an output voltage actual value and an output voltage target value is calculated, and the duty ratio of a PWM signal is amended, so that closed-loop feedback control for voltage regulation is realized, three-phase alternating current with constantly changing voltage amplitude can be converted into stable direct current capable of charging a storage battery, and the operation is stable and reliable.

Description

[0001] Technical field: [0002] The invention belongs to electromechanical integration equipment, and mainly relates to a vibration energy recovery device of a vehicle suspension system, which is used for recovery of the vibration energy of the vehicle suspension system. Background technique [0003] With the development of full electrification, digitalization and informatization of vehicles, more and more in-vehicle devices need power supply and energy consumption, and energy supply has become a key factor restricting vehicle battery life. For example, the advanced active suspension system can effectively dampen the vibration of the car body and greatly improve the ride comfort and ride comfort of the vehicle, but at the cost of consuming external energy. At the same time, the impact load and vibration energy transmitted to the vehicle body by the uneven road surface during the driving process of the vehicle is an important part of the energy consumption of the vehicle. It ...
