Description

Technical Field

[0001] This invention relates to the field of electromagnets, and in particular to a vibration-damping electromagnet. Background Technology

[0002] An electromagnet is a device that generates electromagnetic fields when an electric current flows through it. A conductive winding, matching the power rating of the iron core, is wound around the outside. This current-carrying coil exhibits magnetism like a magnet, hence the name electromagnet. An electromagnet is magnetic when energized, and the magnetism disappears when the power is turned off. It has extremely wide applications in our daily lives, and its invention has greatly improved the power output of generators.

[0003] Existing shock-absorbing electromagnets typically combine electromagnets and permanent magnets. Since the magnetic force is a fixed force, it will generate a rebound force when responding to different external forces, making the shock absorption process uneven. Summary of the Invention

[0004] In order to overcome the shortcomings of existing technical solutions, the present invention provides a shock-absorbing electromagnet that can solve the problems mentioned in the background art.

[0005] The technical solution adopted by this invention to solve its technical problem is: A shock-absorbing electromagnet includes an upper fixed plate and a lower fixed plate. The bottom end of the upper fixed plate is provided with a frame, and the frame is provided with four through slots. Electromagnetic rails are installed in each of the four through slots. A bottom cover is installed at the end of the frame away from the upper fixed plate. A positioning hole is opened in the middle of the bottom cover. A base is provided at the upper end of the lower fixed plate. A housing is provided at the upper end of the base. An electromagnetic column is provided inside the housing. The electromagnetic column and the housing are perpendicular to the base. One end of the electromagnetic column extends into the interior of the base. An energized coil is provided inside the base. The energized coil surrounds the periphery of the electromagnetic column. The housing is provided outside the electromagnetic column. The inner wall of the housing is provided with four grooves. Metal conductive sheets are provided in the grooves. One end of the metal conductive sheets extends into the interior of the base and is connected to the energized coil. The inner wall of the housing is movably connected to the surface of the frame. The electromagnetic guide rail is composed of several electromagnetic blocks. Each electromagnetic block has a connecting plate at one end near the frame surface. The connecting plate is made of insulating plastic and has a conductive contact point at one end near the metal conductive sheet that contacts the metal conductive sheet. When powered on, the energized coil magnetizes the electromagnetic column, and the metal conductive sheet contacts the conductive contact, causing the electromagnetic block to generate a magnetic field opposite to that of the electromagnetic column.

[0006] Furthermore, the surface of the frame is provided with two bosses, and the inner wall of the shell is provided with two grooves that match the shape of the bosses.

[0007] Furthermore, an insulating back plate is installed at one end of the metal conductive sheet near the housing, and the insulating back plate is connected to the housing by several springs.

[0008] Furthermore, the electromagnetic column is made of silicon steel and is screwed to the base.

[0009] Furthermore, a buffer block is provided at the top of the base and at the end of the electromagnetic column away from the base, and the buffer block is made of elastic rubber.

[0010] Compared with the prior art, the beneficial effects of the present invention are: with the electromagnetic rail provided, the greater the external force, the more the electromagnetic rail is energized, the greater the magnetic force generated, and the magnetic force changes with the change of external force, making the shock absorption process smoother.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0013] The following is combined with Figures 1-5The corrosion-resistant electronic wire of the present invention is described in detail as follows: A shock-absorbing electromagnet includes an upper fixed plate 2 and a lower fixed plate 1. A frame 3 is provided at the bottom end of the upper fixed plate 2. The frame 3 is provided with four through slots 4. Electromagnetic rails 5 are installed in each of the four through slots 4. A bottom cover 6 is installed at the end of the frame 3 away from the upper fixed plate 2. A positioning hole is opened in the middle of the bottom cover 6. A base 7 is provided at the upper end of the lower fixed plate 1. A housing 8 is provided at the upper end of the base 7. An electromagnetic column 10 is provided inside the housing 8. The electromagnetic column 10 and the housing 8 are perpendicular to the base 7. One end of the electromagnetic column 10 extends into the interior of the base 7. An energized coil 9 is provided inside the base 7. The energized coil 9 surrounds the periphery of the electromagnetic column 10. The housing 8 is provided outside the electromagnetic column 10. Four grooves are provided on the inner wall of the housing 8. Metal conductive sheets 11 are provided in the grooves. One end of the metal conductive sheets 11 extends into the interior of the base 7 and is connected to the energized coil 9. The inner wall of the housing 8 is movably connected to the surface of the frame 3.

[0014] The electromagnetic guide rail 5 is composed of several electromagnetic blocks 501. Each electromagnetic block 501 has a connecting plate 502 at one end near the surface of the frame 3. The connecting plate 502 is made of insulating plastic. The end of the connecting plate 502 near the metal conductive sheet 11 is provided with a conductive contact 503 that contacts the metal conductive sheet 11. The end of the metal conductive sheet 11 near the housing 8 is provided with an insulating back plate. The insulating back plate is connected to the housing 8 by several springs.

[0015] In this embodiment, a shock-absorbing electromagnet, when energized, has a coil 9 magnetizing an electromagnetic column 10. A metal conductive sheet 11 contacts a conductive contact 503, causing the electromagnetic block 501 to generate a magnetic field opposite to that of the electromagnetic column 10. The greater the external force on the upper fixing plate 2, the larger the contact area between the frame 3 and the housing 8, the more conductive contacts 503 contact the metal conductive sheet 11, and the more magnetized the electromagnetic block 501, resulting in a greater magnetic force opposite to that of the electromagnetic column 10.
