The present invention relates to a low power solenoid structure, capable of minimizing solenoid power. According to the present invention, the low power solenoid structure comprises: a frame including a hole having a surface opened; an operating core moving inside the hole of the frame and having magnetic force; a solenoid comprising a secondary coil to move the operating core with gravitation power by being wound on the frame, and a first coil to move the operating core with repulsive force; and a spring placed on the operating core and the inside the hole of the frame to elastically support the operating core toward the outside. Therefore, the present invention performs a latch function by performing the flow control of the operating core through one coil, and controls the operation maintenance of the operating core with a trigger signal by offsetting the magnetization of the operating core through controlling another coil, and therefore, consumption power for solenoid control is reduced. |
