Description

Technical Field

[0001] The utility model belongs to the technical field of wireless transmission, and particularly relates to an enhanced magnetic coupling wireless transmission device. Background Art

[0002] Traditional magnetic coupling wireless transmission devices usually use a single set of coils for energy transmission, and their magnetic field intensity and transmission efficiency are relatively low. In order to improve the wireless transmission efficiency and transmission distance, the existing methods are as follows: increasing the number of coil turns, using high magnetic permeability materials, or optimizing the coil structure.

[0003] However, the existing methods for improving the wireless transmission efficiency and transmission distance all have certain limitations. For example, increasing the number of coil turns will cause the coil volume to increase, using high magnetic permeability materials will increase the material cost, and optimizing the coil structure may reduce the coupling coefficient between coils. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the utility model provides an enhanced magnetic coupling wireless transmission device, which does not need to increase the number of coil turns, does not need to use high magnetic permeability materials, and does not need to optimize the coil structure. Therefore, it does not need to increase the coil volume, nor will it increase the material cost, and will not reduce the coupling coefficient between coils. Only by changing the layout form of the coils can the enhancement of the magnetic field intensity be achieved, thereby improving the wireless transmission efficiency and transmission distance.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: an enhanced magnetic coupling wireless transmission device, comprising a plurality of magnetic coupling wireless transmission modules, and the plurality of magnetic coupling wireless transmission modules adopt a linear array layout form.

[0006] The magnetic coupling wireless transmission module includes an alternating current power supply, a compensation capacitor, and a coil magnetic coupling assembly; the compensation capacitor and the coil magnetic coupling assembly are connected in parallel and are jointly connected to the alternating current power supply.

[0007] The coil magnetic coupling assembly includes a first electromagnetic unit, a second electromagnetic unit, a third electromagnetic unit, and a fourth electromagnetic unit; the first electromagnetic unit, the second electromagnetic unit, the third electromagnetic unit, and the fourth electromagnetic unit are connected in series.

[0008] The first electromagnetic unit, the second electromagnetic unit, the third electromagnetic unit, and the fourth electromagnetic unit have the same structure, and each includes a bobbin and a protective shell; the bobbin adopts a cylindrical structure, and the protective shell adopts a cylindrical structure; the protective shell is coaxially sleeved outside the bobbin, and there is a winding space for the coil between the protective shell and the bobbin.

[0009] The wire hubs of the first electromagnetic unit and the third electromagnetic unit are distributed in parallel; the wire hubs of the second electromagnetic unit and the fourth electromagnetic unit are distributed coaxially; the wire hubs of the first electromagnetic unit and the third electromagnetic unit are distributed perpendicular to the wire hubs of the second electromagnetic unit and the fourth electromagnetic unit.

[0010] The wire hubs between the first electromagnetic unit and the second electromagnetic unit, between the second electromagnetic unit and the third electromagnetic unit, and between the third electromagnetic unit and the fourth electromagnetic unit are fixedly connected by hollow studs.

[0011] The coils in the first electromagnetic unit, the second electromagnetic unit, the third electromagnetic unit and the fourth electromagnetic unit are connected in series in sequence, and the central holes of the hollow studs serve as the series wiring holes for the coils of adjacent electromagnetic units.

[0012] Advantages of the present utility model:

[0013] For the enhanced magnetic coupling wireless transmission device of the present utility model, there is no need to increase the number of coil turns, no need to use high magnetic permeability materials, and no need to optimize the coil structure.

Detailed implementation manners

[0018] The following further describes the present utility model in detail with reference to the drawings and specific embodiments.

[0019] As Figures 1 to 3 shown, an enhanced magnetic coupling wireless transmission device includes a plurality of magnetic coupling wireless transmission modules, and the plurality of magnetic coupling wireless transmission modules adopt a linear array layout form.

[0020] The magnetic coupling wireless transmission module includes an alternating current power supply 1, a compensation capacitor 2, and a coil magnetic coupling assembly 3; the compensation capacitor 2 and the coil magnetic coupling assembly 3 are arranged in parallel and are jointly connected to the alternating current power supply 1.

[0021] The coil magnetic coupling assembly 3 includes a first electromagnetic unit 4, a second electromagnetic unit 5, a third electromagnetic unit 6, and a fourth electromagnetic unit 7; the first electromagnetic unit 4, the second electromagnetic unit 5, the third electromagnetic unit 6, and the fourth electromagnetic unit 7 are connected in series.

[0022] The first electromagnetic unit 4, the second electromagnetic unit 5, the third electromagnetic unit 6, and the fourth electromagnetic unit 7 have the same structure, and each includes a wire hub 8 and a protective shell 9; the wire hub 8 adopts a cylindrical structure, and the protective shell 9 adopts a cylindrical structure; the protective shell 9 is coaxially sleeved outside the wire hub 8, and a winding space for a coil 10 is left between the protective shell 9 and the wire hub 8.

[0023] The wire hubs 8 of the first electromagnetic unit 4 and the third electromagnetic unit 6 are distributed in parallel; the wire hubs 8 of the second electromagnetic unit 5 and the fourth electromagnetic unit 7 are coaxially distributed; the wire hubs 8 of the first electromagnetic unit 4 and the third electromagnetic unit 6 are perpendicular to the wire hubs 8 of the second electromagnetic unit 5 and the fourth electromagnetic unit 7.

[0024] The wire hub 8 of the first electromagnetic unit 4 and the wire hub 8 of the second electromagnetic unit 5, the wire hub 8 of the second electromagnetic unit 5 and the wire hub 8 of the third electromagnetic unit 6, and the wire hub 8 of the third electromagnetic unit 6 and the wire hub 8 of the fourth electromagnetic unit 7 are all fixedly connected by hollow studs 11.

[0025] The coils 10 in the first electromagnetic unit 4, the second electromagnetic unit 5, the third electromagnetic unit 6, and the fourth electromagnetic unit 7 are sequentially connected in series, and the central holes of the hollow studs 11 serve as the series wiring holes for the coils 10 of adjacent electromagnetic units.

[0026] The following describes a primary usage process of the present utility model with reference to the accompanying drawings:

[0027] In this embodiment, the coils 10 of the first electromagnetic unit 4, the second electromagnetic unit 5, the third electromagnetic unit 6, and the fourth electromagnetic unit 7 can effectively form a Halbach array under a specific spatial layout, thereby enhancing the magnetic field strength in a specific direction.

[0028] In use, first start the alternating current power supply 1. Through the coils 10 in the first electromagnetic unit 4, the second electromagnetic unit 5, the third electromagnetic unit 6 and the fourth electromagnetic unit 7, the four electromagnetic units can respectively generate alternating magnetic fields. The four alternating magnetic fields can be superimposed and enhanced in a specific direction, while canceling each other out in other directions, thereby forming a unidirectionally enhanced magnetic field, ultimately increasing the magnetic field strength, and further improving the wireless transmission efficiency and transmission distance.

[0029] During the wireless transmission process, the compensation capacitor 2 can filter out the clutter and interference signals existing in the alternating current power supply 1, improve the power supply quality, and thus improve the stability of wireless transmission. At the same time, the compensation capacitor 2 can also adjust the equivalent impedance of the coil 10 to match the impedance of the load, thereby improving the wireless transmission efficiency.

[0030] In addition, before use, the distance between the wire hubs 8 of adjacent electromagnetic units can be adjusted by screwing the hollow stud 11, thereby changing the distance between the coils 10 of adjacent electromagnetic units, changing the degree of superposition between the alternating magnetic fields, and ultimately changing the strength of the unidirectionally enhanced magnetic field, and finally changing the wireless transmission efficiency and transmission distance.
