[0020] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0021] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0023] Reference Figure 1-4 An electromagnetic induction element comprises a mounting base 1 and a protective panel 2. The mounting base 1 is provided with a protective panel 2 on the front and back sides thereof by screw connection. A plurality of U-shaped cores 4 are provided inside the mounting base 1. Magnetic induction coils 5 are wound on the surfaces of the U-shaped cores 4. Adjacent U-shaped cores 4 are perpendicular to each other. A plurality of U-shaped cores 4 perpendicular to each other and with their ends butted against each other are provided inside the mounting base 1. The magnetic induction coils 5 wound on the surfaces generate a magnetic field for electromagnetic induction after being energized. The magnetic fields generated by the magnetic induction coils 5 on the surfaces of the U-shaped cores 4 inside the entire mounting base 1 after being energized affect each other, thereby increasing the coverage range of the magnetic field. At the same time, the range of magnetic field generation is expanded from the horizontal and vertical directions, thereby effectively increasing the range of electromagnetic induction.

[0024] In order to increase the adaptability of electromagnetic induction of the entire device, a connecting substrate 6 is provided on the front of the protective panel 2, and a wiring hole 7 is provided on the surface of the connecting substrate 6. The connecting substrate 6 is connected to both ends of the magnetic induction coil 5, and the connecting substrate 6 is embedded in the surface of the protective panel 2. The positions of the connecting substrate 6 and the magnetic induction coil 5 on the surface of the U-shaped iron core 4 correspond one to one. The entire magnetic induction coil 5 is energized mainly through the end connected to the back of the connecting substrate 6, and is energized for use after being connected to an external power supply through the node wire holes on the surface of the connecting substrate 6. The corresponding hierarchical induction coils can be energized through the connecting substrate 6 according to needs for induction use. For example, the magnetic induction coils 5 on the surface of the first, third, and fourth U-shaped iron core 4 are energized for use. At this time, the magnetic fields generated at the first, third, and fourth positions are the strongest, and adjacent magnetic fields are staggered. At this time, the corresponding external magnetic field can be sensed through the strength and type of the generated magnetic field. The corresponding magnetic induction coil 5 can be energized according to actual use needs, thereby effectively increasing the adaptability of electromagnetic induction when used.

[0025] In order to increase the adaptability and coverage of the entire electromagnetic induction, the ends of adjacent U-shaped cores 4 are arranged to abut against each other, and the numbers of turns of the magnetic induction coils 5 wound on the surfaces of adjacent U-shaped cores 4 are different, so that the number of turns of the magnetic induction coils 5 of the adjacent U-shaped cores 4 is a variable, and different magnetic field intensities are generated after power is turned on, thereby increasing the adaptability of the magnetic field size and type. The magnetic induction coils 5 at both ends of the same U-shaped core 4 are wound with the same number of turns, and the magnetic induction coils 5 on the surface of the same U-shaped core 4 are wound in opposite directions. The variables of the magnetic field generated by the same U-shaped core 4 are controlled, so that the same U-shaped core 4 generates a magnetic field with the same magnetic field size and opposite direction, which is convenient for the U-shaped core 4 to be used alone for induction. The U-shaped cores 4 inside the mounting base 1 are of the same size, and the cross-sectional diameters of the magnetic induction coils 5 on the surfaces of adjacent U-shaped cores 4 are the same, thereby reducing the variables of different magnetic fields generated by adjacent U-shaped cores 4, and facilitating the control and selection of the corresponding U-shaped core 4 for use.

[0026] Other limiting structures of the entire device are that ventilation fans 3 are embedded in the top and bottom surfaces of the mounting base 1, and the ventilation fans 3 on the top and bottom surfaces of the mounting base 1 are staggered. Through the arrangement of the ventilation fans 3, heat can be dissipated for each magnetic induction coil 5 inside the entire mounting base 1 when energized. The front size of the protective surface is the same as the size of the front edge of the mounting base 1, and the edges of the mounting base 1 and the protective panel 2 are deburred. Specific embodiment 2:

[0028] Reference Figure 1-4 When the entire device is actually used, an external power source corresponding to the magnetic induction coil 5 needs to be set, such as a battery, which can be used to power the magnetic induction coil 5 after connecting to the wiring hole 7, so as to facilitate the formation of the magnetic field and realize the use of electromagnetic induction. At the same time, the ventilation fan 3 can be powered by the power supply, which is convenient for the operation of the ventilation fan 3 and increases the heat dissipation function of the entire device. Specific embodiment three:

[0030] Reference Figure 1-4 The entire device is connected to the substrate 6 and the magnetic induction coil 5 is generally connected through the surface contacts. The thickness, number of turns and winding direction of the magnetic induction coil 5 generated on the surface of the U-shaped iron core 4 are set based on the content of the above embodiment 1 and the magnetic field induction requirements during actual use.

[0031] In summary:

[0032] A plurality of U-shaped iron cores 4 which are perpendicular to each other and butted against each other at the ends are provided inside the mounting base 1, and a magnetic field is generated when a magnetic induction coil 5 is wound on the surface and energized for use in electromagnetic induction. The magnetic fields generated by the magnetic induction coils 5 on the surfaces of the U-shaped iron cores 4 inside the entire mounting base 1 after energization affect each other, thereby increasing the coverage of the magnetic field and expanding the range of the magnetic field generation in the horizontal and vertical directions, thereby effectively increasing the range of electromagnetic induction. At the same time, the corresponding hierarchical sense coils can be energized for use induction through the connecting substrate 6 as needed, thereby increasing the adaptability of electromagnetic induction when used.
