The operation principle of the present invention is that: when cargo is static or when driving, cylindrical shell and base cylindrical by
When airflow function, vibration can be generated, vibration causes spring deformation occurs deformation, and spring deformation metamorphosis is in piezoelectric ceramic thin sheet
With the power of piezoelectric ceramics on piece, cause piezoelectric ceramic thin sheet and piezoelectric ceramic piece that flexible deformation bending, piezoelectric ceramic thin sheet occurs
When deforming with piezoelectric ceramic piece, electric current, then the electricity by being connected to piezoelectric ceramic thin sheet and piezoelectric ceramics on piece can be generated
It charges directly to Vehicular accumulator cell in circuit.
The process of energy conversion: air-flow flows through the vibrational energy generated when disturbing flow device, passes it to pressure by spring
Electroceramics thin slice, piezoelectric ceramic thin sheet converts vibrational energy into electric energy again, then charges to Vehicular accumulator cell.When van-type goods
Vehicle when driving, is mounted on function of the disturbing flow device of booth upper in addition to carrying out energy regenerating, also acts as a part of eddy generator
Effect.When windstream flows through disturbing flow device cylindrical shell, disturbing flow device will generate the relatively stronger whirlpool of intensity,
After the whirlpool of this high-energy is mixed with low-energy boundary layer air flowing downstream, boundary layer just is given energy transmission, has made to locate
Boundary layer flow field in adverse pressure gradient can continue to be attached to carriage body surface and will not separate after obtaining additional-energy, also just press down
Vortex shedding has been made, air drag suffered by cargo is reduced.
The utility model has the advantages that disturbing flow device of the invention can recycle wind energy, it is converted into electric energy and stores, improves the energy
Utilization rate；And cargo when driving, moreover it is possible to play the role of eddy generator, reduce in driving process suffered by cargo
Air drag.
