Detailed Description
The technical scheme of the utility model is further explained in detail with the attached drawings as follows:
the utility model mainly comprises a magnetic conduction plate 1, a magnet 2 polarized up and down, an E-shaped iron core 3 and a coil 4, as shown in figures 1 and 2. Assembly of the generator assembly see fig. 2, the coil 4 is wound around the middle arm 32 of the E-core 3.
The combination of the magnetic conductive plate 1 and the vertically polarized magnet 2 is shown in fig. 3, two ends of the upper magnetic conductive plate 11 are respectively provided with a guide magnetic pole 110, 111, the upper guide magnetic pole 111 of the upper magnetic conductive plate is fixedly contacted with the upper surface magnetic pole 21 of the magnet, and the other end extends to a horizontal position with the lower surface magnetic pole 22 of the magnet towards the lower side of one side of the magnet 2, and forms a lower guide magnetic pole 110 of the upper magnetic conductive plate. The two ends of the lower magnetic conductive plate 12 are also respectively provided with a guide magnetic pole 120, 121, the lower guide magnetic pole 121 of the lower magnetic conductive plate is fixedly contacted with the lower surface magnetic pole 22 of the magnet, and the other end of the lower magnetic conductive plate extends to the horizontal position with the upper surface magnetic pole 21 of the magnet towards the upper part of the other side of the magnet 2, so that the upper guide magnetic pole 120 of the lower magnetic conductive plate is formed. The distribution structure of the guide magnetic poles of the magnetic conduction plate 1 enables the two magnetic poles of the magnet 2 to be distributed on an upper horizontal plane and a lower horizontal plane in a staggered mode. In cooperation with the E-core 3, it is ensured that the flux variation in the coil 4 is maximized.
The power generation device has two stable states, and the E-shaped iron core 3 is attracted with the guide magnetic pole. Fig. 4 illustrates a first stable state of the power plant. The end of the E-shaped iron core 3 is attracted with the two guide magnetic poles 111 and 120 at the upper end. The middle arm 32 of the E-shaped iron core 3 is in attraction contact with the upper guide magnetic pole 111 of the upper magnetic conductive plate, and the left arm 31 of the E-shaped iron core 3 is in attraction contact with the upper guide magnetic pole 120 of the lower magnetic conductive plate. When the polarization direction of the magnet 2 is from bottom to top, the N pole is at the top, the S pole is at the bottom, and the direction of the magnetic force line in the state is as follows: the N pole of the magnet 2 → the upper pilot pole 111 of the upper magnetic conductive plate → the middle arm 32 of the E-shaped core 3 → the left arm 31 of the E-shaped core 3 → the upper pilot pole 120 of the lower magnetic conductive plate → the S pole of the magnet 2, forming a closed loop of magnetic lines of force.
Fig. 5 shows another steady state. The tail end of the E-shaped iron core 3 is attracted with the two lower guide magnetic poles 110 and 121. The middle arm 32 of the E-shaped iron core 3 is in attraction contact with the lower guide magnetic pole 121 of the lower magnetic conductive plate, and the right arm 33 of the E-shaped iron core 3 is in attraction contact with the lower guide magnetic pole 110 of the upper magnetic conductive plate. When the polarization direction of the magnet 2 is from bottom to top, the N pole is at the top, the S pole is at the bottom, and the direction of the magnetic force line in the state is as follows: the N pole of the magnet 2 → the lower pilot pole 110 of the upper magnetic conductive plate → the right arm 33 of the E-shaped core 3 → the middle arm 32 of the E-shaped core 3 → the lower pilot pole 121 of the lower magnetic conductive plate → the S pole of the magnet 2, forming a closed loop of magnetic lines of force.
It can be seen that in both stable states, most of the magnetic lines of force of the magnet 2 penetrate the middle arm 32 of the E-core 3, and the direction of the magnetic lines of force is reversed. The flux variation in the coil 4 is thus maximised when switching between the two stable states.
The conversion of two stable states of the power generation device mainly reflects the relative motion between the E-shaped iron core 3 and two stable states of the magnet 2 and the magnetic conduction plate 1, but the rotor and the stator are not limited. The magnet 2 and the magnetic conduction plate 1 can be fixed, and the E-shaped iron core 3 (or the coil 4) moves in the pressing action. The E-shaped iron core 3 and the coil 4 can be fixed, and the magnet 2 and the magnetic conduction plate 1 move under the action of pressing.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention.
