[0033] 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.

[0034] This utility model embodiment provides a wireless charging device, such as... Figures 1 to 3 As shown, the wireless charging device includes a base 1 and a wireless charging panel 2. A control circuit board 11 is provided inside the base 1 and is rotatably connected to one side of the base 1 to the wireless charging panel 2, so that the wireless charging panel 2 can rotate to fit against the first surface 12 of the base 1 or rotate to stand up from the first surface 12.

[0035] The wireless charging panel 2 includes a housing 21 and a magnetic wireless charging module 22. The magnetic wireless charging module 22 of the wireless charging panel 2 is electrically connected to the control circuit board 11. The housing 21 includes a top shell 211, a bottom shell 212 and a middle shell 213 installed between the top shell 211 and the bottom shell 212. The top shell 211 is away from the base 1 and the bottom shell 212 faces the base 1. The magnetic wireless charging module 22 is installed on the side of the middle shell 213 facing the top shell 211.

[0036] The wireless charging panel 2 of this utility model divides the housing 21 into a top shell 211, a bottom shell 212, and a middle shell 213 installed between the top shell 211 and the bottom shell 212. Compared to having only a top shell 211 and a bottom shell 212, the independently set middle shell 213 can be used to install a magnetic wireless charging module. In this way, it can ensure that the magnetic wireless charging module 22 is close enough to the top shell 211 to ensure charging efficiency and magnetic attraction to the charging device. At the same time, the middle shell 213 can be made of a material with high structural strength, so that the middle shell 213 and the top shell 211 can be manufactured separately in production, ensuring that the magnetic wireless charging module 22 has sufficient installation strength when installed in the middle shell 213.

[0037] Specifically, the magnetic wireless charging module 22 charges mobile phones. When in use, the wireless charging panel 2 can be rotated to stand upright, facilitating magnetic placement of the phone. When not in use, it rotates and adheres to the first surface 12 of the base 1 for storage. The top shell 211 can be injection molded from liquid silicone, while the middle shell 213 and bottom shell 212 are made of polycarbonate (PC). The liquid silicone injection-molded top shell 211 provides a softer charging contact interface for the phone, while the polycarbonate material provides sufficient structural strength. The top shell 211, middle shell 213, and bottom shell 212 can be fastened together using clips or screws; specific limitations are not specified here.

[0038] like Figure 5 , Figure 8 , Figure 10 and Figure 11The wireless charging panel 2 is rotatably connected to the base 1 via a pivot assembly 3. The pivot assembly 3 includes a pivot 31 and a rotating plate 32. The pivot 31 is installed in the base 1, and the rotating plate 32 is rotatably sleeved on the pivot 31. A connecting plate 23 is installed on the side of the middle shell 213 facing the bottom shell 212, and the rotating plate 32 is installed on the connecting plate 23. The pivot assembly 3 allows the wireless charging panel 2 to rotate flexibly on the base 1, making it convenient to stand the panel upright for magnetic charging during use and to attach it to the base 1 for storage when not in use, thus improving the ease of use and space adaptability of the wireless charging device.

[0039] The rotating shaft 31 is installed in the base 1, providing a stable fulcrum for rotation; the rotating plate 32 is rotatably sleeved on the rotating shaft 31, and the connecting plate 23 is installed on the rotating plate 32. The connecting plate 23 is also installed on the side of the middle shell 213 facing the bottom shell 212, realizing the rotational connection of the wireless charging panel 2, while also ensuring the firmness of the connection, and being able to withstand various forces during the rotation of the wireless charging panel 2, ensuring the wireless charging device and durability of the device.

[0040] Specifically, the hinge assembly 3 is installed via the connecting plate 23, and the middle shell 213 can provide sufficient installation strength for the hinge assembly 3. At the same time, the rotating plate 32 and the magnetic wireless charging module 22 are both installed on the middle shell 213, realizing modular integration and facilitating the assembly of the wireless charging panel 2.

[0041] Specifically, the connecting plate 23, the rotating shaft 31, and the rotating plate 32 are all metal parts. The connecting plate 23 is mounted on the middle shell 213 with screws, and the rotating plate 32 is mounted on the connecting plate 23 with screws. The rotating plate 32 is rotated and tightened on the rotating shaft 31, generating damping so that the wireless charging panel 2 can be maintained at the rotation angle. Specifically, an inner bracket 13 is provided inside the base 1. The rotating shaft 31 is mounted on the inner bracket 13 with screws, and the main control circuit board is mounted on the inner bracket 13 with screws. The inner bracket 13 is then mounted in the base 1 with screws. The main control circuit board is the power control and distribution component of the wireless charging device. It can be set up using conventional technical means, and no specific restrictions are made here.

[0042] Further integration Figure 8 and Figure 9 As shown, a first wiring groove 231 is provided on the side of the connecting plate 23 facing the middle shell 213, and the wires 225 of the magnetic wireless charging module 22 pass through the first wiring groove 231. The configuration of the first wiring groove 231 provides an orderly wiring path for the wires 225 of the magnetic wireless charging module 22, so that the wires 225 can be neatly arranged and fixed on the connecting plate 23, avoiding messy tangling of the wires 225 and improving the safety and reliability of the wireless charging device.

[0043] A first wiring groove 231 is provided on the side of the connecting plate 23 facing the middle shell 213. After the wires 225 of the magnetic wireless charging module 22 are led out from the module, they can pass into the first wiring groove 231. The wiring groove constrains and guides the wires 225, reducing the pulling, wear, or interference with the normal operation of other components during the rotation of the wireless charging panel 2, and ensuring the stability of the connection between the wires 225 and the magnetic wireless charging module 22 and subsequent circuits. After the wires 225 are led out from the rotation connection of the wireless charging panel 2, they are introduced into the base 1 and electrically connected to the control circuit board 11.

[0044] like Figure 12 As shown, the middle shell 213 is provided with a second wiring groove 2131 corresponding to the first wiring groove 231, and the first wiring groove 231 and the second wiring groove 2131 are engaged. The middle shell 213 is provided with the second wiring groove 2131 at the position corresponding to the first wiring groove 231. When the connecting plate 23 is installed on the middle shell 213, the first wiring groove 231 and the second wiring groove 2131 are engaged to form a complete wiring channel, providing sufficient wiring space for guide layout.

[0045] like Figure 6 As shown, a coil groove 2111 and a magnetic ring groove 2112 surrounding the coil groove 2111 are provided on the side of the top shell 211 facing the middle shell 213. The magnetic wireless charging module 22 includes a charging coil 222 and a magnetic ring 221 surrounding the charging coil 222. The charging coil 222 is located in the coil groove 2111, and the magnetic ring 221 is located in the magnetic ring groove 2112. In this design, a coil groove 2111 and a magnetic ring groove 2112 surrounding the coil groove 2111 are provided on the side of the top shell 211 facing the middle shell 213. The charging coil 222 of the magnetic wireless charging module 22 is placed in the coil groove 2111, and the magnetic ring 221 is installed in the magnetic ring groove 2112. The charging coil 222 and the magnetic ring 221 are positioned and fixed by the constraints of the coil groove 2111 and the magnetic ring groove 2112. Specifically, the wire 225 is connected to the charging coil 222.

[0046] The magnetic ring groove 2112 has a wiring notch 2113 on the side near the first wiring groove 231. The wires 225 of the magnetic wireless charging module 22 are led out from the wiring notch 2113 and introduced into the first wiring groove 231 and the second wiring groove 2131.

[0047] The opening of the wiring notch 2113 provides a convenient channel for the wires 225 of the magnetic wireless charging module 22 to be led out from the magnetic ring groove 2112 side, so that the wires 225 can be smoothly led out from near the magnetic ring groove 2112 and enter the first wiring groove 231 and the second wiring groove 2131. This avoids the wires 225 being obstructed by the magnetic ring groove 2112 during the wiring process, ensuring the smoothness and rationality of the wiring of the wires 225, and further improving the reliability and safety of the device.

[0048] Specifically, the coil groove 2111 and the magnetic ring groove 2112 are formed by the rib 2114. The coil groove 2111 is circular and the magnetic ring groove 2112 is ring-shaped.

[0049] The magnetic wireless charging module 22 also includes a mounting plate 223, which is installed on the side of the middle shell 213 facing the top shell 211. The charging coil 222 and the magnetic ring 221 are mounted on the mounting plate 223. The mounting plate 223 provides an independent mounting platform for the charging coil 222 and the magnetic ring 221, allowing the magnetic wireless charging module 22 to be mounted more stably on the middle shell 213. This modular design improves the overall structural strength and stability of the magnetic wireless charging module 22, and also facilitates the assembly, disassembly, and replacement of the magnetic wireless charging module 22, enhancing production flexibility and maintenance convenience. Specifically, the magnetic ring 221 is composed of multiple magnets arranged in a ring shape, and the charging coil 222 and the magnetic ring 221 can be fixed to the mounting plate 223 with glue or the like.

[0050] The wireless charging module includes a wireless charging circuit board 224, which is mounted on the side of the mounting plate 223 near the second wiring groove 2131. The wireless charging circuit board 224 is electrically connected to the charging coil 222 and the control circuit board 11 via wires 225. A clearance opening 2132 is provided on the middle shell 213 corresponding to the wireless charging circuit board 224, allowing space to be provided for the components on the wireless charging circuit board 224. The clearance opening 2132 provides sufficient space for the components on the wireless charging circuit board 224, preventing interference from the middle shell 213 and ensuring that the wireless charging circuit board 224 can be properly installed and operate on the mounting plate 223. It also facilitates heat dissipation and optimizes the layout of components, improving the performance and reliability of the wireless charging device. The components are necessary electronic components on the wireless charging circuit board 224, such as resistors, which can be set according to actual needs and will not be described in detail here.

[0051] Specifically, the charging coil 222 is connected to the wireless charging circuit board 224 via a wire 225, and the wireless charging circuit board 224 is then electrically connected to the control circuit board 11 via a wire 225, thereby realizing the electrical connection between the magnetic wireless charging module 22 and the control circuit board 11. The wire 225 of the charging coil 222 is led out from the wiring notch 2113 and connected to the wireless charging circuit board 224. The wire 225 of the wireless charging circuit board 224 passes through the first wiring groove 231 and the second wiring groove 2131, and is led out from the rotating connection of the wireless charging panel 2 and introduced into the base 1 to connect with the control circuit board 11.

[0052] Two opposing mounting ears 2231 are provided on the side of the mounting plate 223 near the second wiring groove 2131. The two ends of the wireless charging circuit board 224 are respectively mounted on the two mounting ears 2231; a clearance opening 2132 is located between the two mounting ears 2231. The mounting ears 2231 provide reliable mounting support points for the wireless charging circuit board 224, allowing it to be firmly mounted on the mounting plate 223. This improves the mounting strength and stability of the wireless charging circuit board 224, preventing it from loosening or being damaged due to vibration or other external forces during use, and ensuring the normal operation and performance of the wireless charging device. Specifically, the two ends of the wireless charging circuit board 224 are mounted on the two mounting ears 2231 with screws. The mounting plate 223 can be a plastic plate.

[0053] like Figure 10 As shown, a first magnetic attraction structure 24 is installed between the bottom shell 212 and the middle shell 213 inside the wireless charging panel 2, and a second magnetic attraction structure 14 is installed inside the base 1 corresponding to the first magnetic attraction structure 24. When the wireless charging panel 2 rotates and adheres to the first surface 12 of the base 1, the first magnetic attraction structure 24 and the second magnetic attraction structure 14 magnetically attract each other. The cooperative use of the first magnetic attraction structure 24 and the second magnetic attraction structure 14 enables the wireless charging panel 2 to be firmly fixed by magnetic attraction when it rotates and adheres to the first surface 12 of the base 1, preventing the wireless charging panel 2 from loosening or falling off due to external force or vibration in the stored state, thus improving the stability and safety of the wireless charging device.

[0054] Specifically, the first magnetic attraction structure 24 and the second magnetic attraction structure 14 can both be magnets, or one of them can be a magnet and the other can be a metal block that can be magnetically attracted to the magnet, such as an iron block.
