Abstract

A smart active mount apparatus configured for removing a complicated wiring for connecting a controller, a mount, and an engine ECU, a vacuum negative pressure hose, and a controller may include an insulator disposed in a case to define a liquid chamber; a lower orifice plate disposed in the case to partition the liquid chamber into upper and lower liquid chamber; an upper orifice plate disposed above the lower orifice plate; a membrane disposed between the lower and upper orifice plates; a diaphragm disposed under the lower orifice plate, an air chamber defined between the membrane and the lower orifice plate; a solenoid valve connected to the air chamber; and a generator disposed to the diaphragm, the generator generating electrical energy by movement or deformation of the diaphragm to supply the electrical energy as actuating power of the solenoid valve.

First claim

What is claimed is:

1. A smart active mount apparatus comprising:
an insulator disposed in a case to fix an internal core and define a liquid chamber;
a lower orifice plate disposed in the case to partition the liquid chamber into an upper liquid chamber and a lower liquid chamber, and having an orifice to guide a fluid flow between the upper liquid chamber and the lower liquid chamber;
an upper orifice plate disposed above the lower orifice plate;
a membrane disposed between the lower orifice plate and the upper orifice plate;
a diaphragm disposed under the lower orifice plate in the case to define the lower liquid chamber together with the lower orifice plate between the lower orifice plate and the diaphragm;
an air chamber defined between the membrane and the lower orifice plate;
a solenoid valve connected to the air chamber, wherein the air chamber selectively fluidically-communicates with the atmosphere; and
a generator disposed to the diaphragm, the generator generating electric power by movement or deformation of the diaphragm to supply the electric power as actuating power of the solenoid valve,
wherein the generator generates the electric power when the movement of the diaphragm increases while a vehicle travels on a predetermined road, and the solenoid valve is operated to be closed when the electric power generated by the generator reaches a predetermined level, and
wherein the generator generates the electric power which does not reach the predetermined level by the movement of the diaphragm while an engine idles, and the solenoid valve is operated to be opened when the electric power generated by the generator does not reach the predetermined level.

2. The smart active mount apparatus of claim 1 , wherein while the vehicle travels on the predetermined road, a flow of fluid moving from the upper liquid chamber to the lower liquid chamber is increased by moving of the internal core so that the diaphragm is moved and deformed.

3. The smart active mount apparatus of claim 1 , further including a power converter configured to convert the electric power output from the generator to supply the electric power as the actuating power of the solenoid valve.

4. The smart active mount apparatus of claim 3 , wherein the power converter includes a rectifier circuit configured to convert AC power output from the generator into DC power to apply the converted DC power to the solenoid valve.

5. The smart active mount apparatus of claim 3 , wherein an output terminal of the generator is directly connected to an input terminal of the power converter through a wiring, and an output terminal of the power converter, from which the converted electric power is output, is directly connected to a power input terminal of the solenoid valve through a wiring.

6. The smart active mount apparatus of claim 1 , wherein the generator is a nano-generator installed integrally to the diaphragm, the nano-generator including an electrode and a composite including a nanoparticle-sized piezoelectric material.

7. The smart active mount apparatus of claim 6 , wherein the nano-generator has a structure where the composite is laminated on the diaphragm as a substrate.
