The present invention relates to an electromagnet variable magnet unit capable of vibration control and a conversion method thereof.

More specifically, it is mounted on a damper under the driver's seat for the purpose of improving vibration comfort and riding comfort of the seat by shock or excitation transmitted from the outside for the driver's comfortable operation when driving a car, a ship, or heavy equipment for transportation. In the electromagnetic magnet spring for controlling the damper by the electric current input to the, the invention relates to an electromagnet variable magnet unit capable of vibration control transmitted to the seat from the outside and a conversion method thereof,

In particular, by changing the arrangement and direction of the movable side electromagnet in contact with the fixed side electromagnet, the vibration prevention function of the magnet unit (magnet spring) can be automatically changed according to the state of the road surface, and thus the conventional mounting on the seat Freely adjust vibration dampening characteristics of the suspension device of the technology;

It is a very useful invention for an electromagnet variable magnet unit capable of vibration control and a conversion method thereof, in which the vibration control of the configuration in which the component parts are monotonous and the manufacturing cost is greatly reduced is possible.

Drivers who drive commercially operated cars, ships, heavy equipment for transportation, feel very tired because they have to drive for a long time and a long distance with a fixed driver posture.

This difficult working environment accumulates the driver's fatigue and promotes the disease of the occupational driver. In particular, the vibration transmitted from the outside to the seat has a great influence on the cause of the lumbar disease of the driver.

Accordingly, suspension devices having a configuration for reducing fatigue of the human body by minimizing, absorbing and suppressing non-uniform shock or vibration transmitted to the sheet by using vibration isolation devices capable of alleviating vibration transmitted to the sheet have been proposed.

In general, if the dynamic magnification is small in order to improve the low frequency characteristics of the suspension device, it becomes a rigid spring, which deteriorates the high frequency characteristics, thereby reducing vibration. However, the cushioning of the seat is reduced, and the loss factor is increased to improve the high frequency characteristics. The soft springs deteriorate the low-frequency characteristics, improving ride quality but transmitting external vibration to the seat.

Accordingly, there is a problem in that the performance of the conventional suspension device is limited due to various constraints.

As shown in FIG. 10, in order to solve the above problems, the Korean Patent Publication No. 10-2007-0093748 (published on September 19, 2007) discloses a "variable suspension using electromagnetic induction phenomenon" patent.

Suspension device of the method of minimizing, absorbing and suppressing non-uniform shock or vibration transmitted to the seat by varying the rigidity of the coil spring 713 by increasing the rigidity of the conventional coil spring 713 which is weak to shock and controlling the strength of the electromagnetic force. As a configuration to increase the rigidity of the coil spring 713 by controlling the strength of the electromagnetic force, there is a limit to the prevention of vibration transmitted to the seat, and in particular, when the vehicle runs on an unpaved road, vibration transmitted from the outside is transmitted to the seat. There is a difficulty in mitigating vibration of the form desired by the user;
