Problems solved by technology

[0003] However, with this electromagnet structure in the prior art, when the coil 25 is energized, the force with which the moving magnetic pole 24 drives the push rod 23 to stretch out is relatively small, and it is difficult to meet the demand in some occasions that require a large driving force.
In order to increase the force that the moving magnetic pole 24 drives the push rod 23 to stretch out, people generally adopt two methods, the first is to increase the current inside the coil 25, and the second is to increase the coil; however, the first method will increase Power consumption, and lead to serious heating, the second method will lead to excessive coil volume, which is not conducive to the miniaturization of the product

Abstract

The invention provides an electromagnet structure. The electromagnet structure comprises a magnetic pole, a mounting member used for mounting the magnetic pole and guiding the movement of the magnetic pole, and a first coil and a second coil arranged around the mounting member, a first blocking structure is arranged on the mounting member, and a first elastic member is arranged between the magnetic pole and the first blocking structure; when being energized, the first coil generates a magnetic field to attract the magnetic pole to a position close to the first blocking structure, and at this time, the first elastic member is compressed to store energy; when the first coil de-energized, the second coil is energized, the second coil generates a magnetic force to attract the magnetic pole to move towards one side away from the first blocking structure, at this time, the first elastic member releases the energy to propel the magnetic pole to accelerate, so that when the magnetic pole arrives at the position of the second coil, the magnetic pole can obtain a larger speed, and thus being capable of driving the action of a mandril in a larger force. Compared with the prior art, the magnetic pole drives the movement of the mandril in the larger force without increasing the current or the coil, and demands under specific occasions can be satisfied.

Description

technical field [0001] The invention relates to an electromagnet structure and belongs to the technical field of electrical control and protection devices. Background technique [0002] Electromagnet structures are often used in electrical control devices to provide power for control actions. The electromagnet structure in the prior art is as figure 1 As shown, the moving magnetic pole 24 and the static magnetic pole 27 which are arranged relatively are included, wherein the static magnetic pole 27 is fixedly arranged, and the moving magnetic pole 24 can move back and forth relative to the static magnetic pole 27. There is a through hole for driving the push rod 23 to pass through, and a return spring 26 is sleeved on the outer wall of the drive push rod 23, and one end of the return spring 26 contacts with the moving magnetic pole 24, and the other end contacts with the static magnetic pole 27; A coil 25 is also provided on the circumferential outer side of the static mag...
