[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] This utility model embodiment provides a coil device, such as Figure 1 and Figure 2 As shown, the coil device includes multiple stacked and spaced coil assemblies 110. Each coil assembly 110 includes an insulating support plate 111 and at least one spiral coil 112 wound from the center outward. The spiral coil 112 is attached to the outer surface of the insulating support plate 111. At opposite ends of the insulating support plate 111 in a first direction, the insulating support plates 111 of two adjacent coil assemblies 110 are connected by a support assembly 120 to form a gap between the two coil assemblies 110. The spiral coils 112 of the multiple coil assemblies 110 are connected in parallel.

[0027] The coil device provided in this embodiment of the utility model is provided with multiple coil assemblies 110. Each coil assembly 110 includes an insulating support plate 111 and at least one spiral coil 112 wound from the center outwards and attached to the insulating support plate 111. Each spiral coil 112 can generate a magnetic field when energized. At the opposite ends of the insulating support plate 111 in the first direction, the insulating support plates 111 of two adjacent coil assemblies 110 are connected by a support assembly 120, so that the two adjacent coil assemblies 110 are spaced apart to avoid short circuits. At the same time, the multiple coil assemblies 110 are stacked and spaced apart, and their spiral coils 112 are connected in parallel, which can superimpose the magnetic fields of the multiple coil assemblies 110. Compared with the existing coil devices, the magnetic field strength of the entire coil device can be improved to meet the needs of scenarios with larger magnetic field strength.

[0028] The spiral coil 112 can be attached to the insulating support plate 111 with glue, and the glue can be cured and shaped by hot pressing.

[0029] In an optional embodiment of this application, reference is made to Figure 2 The insulating support plate 111 has an arc-shaped structure, and the support assembly 120 is located in the middle of the arc-shaped structure. With the spiral coil 112 attached to the outer surface of the insulating support plate 111, the insulating support plate 111 can surround and cover the human body, better matching the shape of the human body and making the magnetic field distribution more uniform. The support assembly 120, located in the middle of the arc-shaped structure, is closer to the center of gravity of the insulating support plate 111, making the structure stable after the multiple coil assemblies 110 are assembled.

[0030] Specifically, when the spiral coil 112 is attached to the insulating support plate 111 with glue, and the glue is cured and shaped by hot pressing, the insulating support plate 111 is rolled to form an arc-shaped structure.

[0031] Alternatively, the insulating support plate 111 may be made of epoxy resin.

[0032] In an optional embodiment of this application, reference is made to Figure 2 Two spiral coils 112 are attached to each insulating support plate 111. The two spiral coils 112 are distributed along the first direction of the insulating support plate 111 and are connected in parallel.

[0033] By attaching two spiral coils 112 to the insulating support plate 111 and connecting them in parallel, the coil assembly 110 has a larger size and can cover a larger current sensing area.

[0034] refer to Figure 1 and Figure 3 In an optional embodiment of this application, the support component 120 includes a vertically arranged support member 121 and a horizontally arranged connector 122. The support member 121 and the connector 122 are detachably connected and fixed to the insulating support plate 111 through the connector 122. The support members 121 of two adjacent support components 120 are detachably connected to each other.

[0035] Specifically, the vertically arranged support member 121 can effectively withstand vertical forces, separating adjacent insulating support plates 111 and adjacent coil assemblies 110, preventing the spiral coils 112 on adjacent insulating support plates 111 from contacting each other and avoiding short circuits. The horizontally arranged connector 122 can enhance the lateral stability of the structure, connecting and fixing the support member 121 to the insulating support plate 111 together, preventing the coil assembly 110 from shifting laterally. The support member 121 and connector 122 are detachably connected, making disassembly and installation between the support member 121 and connector 122 more convenient, and the support member 121 can be reused and replaced. The detachable connection of the support members 121 of adjacent support assemblies 120 allows multiple coil assemblies 110 and multiple support assemblies 120 to form an integral structure, enhancing the stability of the entire coil device. Designers can also stack and install different numbers of coil assemblies 110 as needed, making assembly flexible. Therefore, this application uses the combination of support member 121 and connector 122 to connect the insulating support plate 111 of adjacent coil assembly 110 together, which has a relatively simple structure, is easy to install and maintain, and is flexible in assembly.

[0036] Optionally, refer to Figure 1 , Figure 3 and Figure 4 The support member 121 has a slot 1211 and a snap-fit ​​part 1212 that mates with the slot 1211 at both ends. The support members 121 of two adjacent support components 120 are connected by snap-fit ​​parts 1212 into the slot 1211.

[0037] The support members 121 of two adjacent support assemblies 120 are installed and connected together by a slot 1211 and a snap-fit ​​part 1212, which allows for quick assembly and disassembly without the need for bolts, nuts, or other tools. This connection method greatly reduces installation time and improves the efficiency of equipment assembly and maintenance. The engagement of the slot 1211 and the snap-fit ​​part 1212 provides a stable mechanical connection, preventing adjacent support members 121 from loosening or falling off during use, and improving the stability of the connection between adjacent coil assemblies 110.

[0038] Optionally, refer to Figures 3 to 5 The support member 121 is provided with a snap-fit ​​hole 1213, and the connector 122 is horizontally snapped into the snap-fit ​​hole 1213.

[0039] The support 121 and the connector 122 are connected together by a snap-fit, thereby fixing the support 121 to the insulating support plate 111. No bolts, nuts or other fastening tools are needed, which greatly improves the efficiency of installation and disassembly, supports quick replacement and disassembly, and the snap-fit ​​structure does not require additional fasteners, reducing space occupation and making the assembly of multiple coil assemblies 110 more compact.

[0040] Optionally, refer to Figure 3 and Figure 4 The side of the support member 121 is provided with a limiting groove 1214, which is used to limit the support assembly 120 on the outer shell in the vertical direction.

[0041] The limiting groove 1214 can precisely limit the position of the support component 120 in the vertical direction, preventing it from being displaced vertically during use. The support component 120 can be more stably fixed on the outer shell, enhancing the stability of the overall structure.

[0042] In an optional embodiment of this application, reference is made to Figure 1 and Figure 3 The connector 122 is provided with pads (not shown in the figure), and the two ends of the spiral coil 112 are electrically connected to the pads of the connector 122 arranged on opposite ends of the insulating support plate 111. Both the connector 122 and the support 121 are made of conductive material.

[0043] Specifically, the spiral coil 112 is electrically connected to the solder pads on the connector 122. The two ends of the spiral coil 112 can be connected to the power circuit through the support components 120 at opposite ends of the insulating support plate 111. That is, the support component 120 not only serves as a mechanical connection structure that separates adjacent coil components 110, but also as an electrical connection structure that realizes the parallel connection of adjacent coil components 110. This eliminates the need for complicated wiring methods, simplifies the electrical connection process, greatly simplifies the assembly of the entire coil device, and improves the assembly efficiency and production efficiency of the coil device.

[0044] In practice, the two ends of the spiral coil 112 are soldered to the corresponding pads of the connector 122, thereby achieving an electrical connection between the spiral coil 112 and the connector 122.

[0045] refer to Figure 1 and Figure 6 In an optional embodiment of this application, the coil device further includes at least two lateral support frames 130 arranged at opposite ends in the second direction of the insulating support plate 111. The lateral support frames 130 are provided with a plurality of support arms 131 corresponding to the insulating support plate 111. Each support arm 131 is used to support an insulating support plate 111. The second direction is perpendicular to the first direction.

[0046] Specifically, the lateral support frame 130 supports multiple insulating support plates 111 through multiple support arms 131, achieving support for the insulating support plates 111 in the second direction. This effectively distributes the load, reduces local stress concentration, and thus improves the stability of the entire coil assembly. The support assembly 120 in the first direction and the lateral support frame 130 in the second direction can support and separate the insulating support plates 111 of the multiple coil assemblies 110 in different directions, improving the stability of the electrical connection and structural stability of the multiple coil assemblies 110.

[0047] Optionally, the first direction is the length direction of the insulating support plate 111, such as... Figure 1 The Y direction shown is the second direction, which is the width direction of the insulating support plate 111, as shown in the figure. Figure 1 As shown in the X direction, the support assembly 120 and the lateral support frame 130 are combined in the length and width directions of the insulating support plate 111 to support the insulating support plate 111, resulting in high structural stability.
