[0032] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0033] like Figures 1 to 4 As shown, a wireless charging device 10 of one embodiment includes a circuit board 100, a bottom shell 200, a top cover 300, a coil 400, and a plurality of function switches 500. The top cover 300 covers the bottom shell 200, the circuit board 100 is mounted on the bottom shell 200, the power supply terminal of the circuit board 100 is used for electrical connection to a power source, the coil 400 is electrically connected to the charging terminal of the circuit board 100, each function switch 500 is electrically connected to a control terminal of the circuit board 100, and the plurality of function switches 500 are arranged around the coil 400. The top cover 300 has a plurality of spaced-apart clearance grooves 311, and the plurality of function switches 500 are located in the corresponding clearance grooves 311 so that the function switches 500 abut against the surface of the top cover 300.
[0034] In this embodiment, the circuit board 100 is mounted on the bottom shell 200. The circuit board 100 is electrically connected to the power supply terminal through wires. The coil 400 is electrically connected to the circuit board 100. Multiple function switches 500 are arranged around the coil 400. The multiple function switches 500 are used to realize different functions of the wireless charging device 10, such as charging state switching, safety protection, pairing or connection control, etc. Each function switch 500 is located in the clearance blocking groove 311 of the upper cover 300. The clearance blocking groove 311 is used to block the electromagnetic interference of the metal conductive parts of the function switch 500 to the coil 400. When the device is started, the alternating current passes through the coil 400 to generate a magnetic field. This magnetic field is induced by the receiving coil 400 of the charging device and forms an electromotive force, thereby causing the charging device to generate current.
[0035] In the aforementioned wireless charging device 10, the circuit board 100 is mounted on the bottom shell 200, the coil 400 is electrically connected to the circuit board 100, and the circuit board 100 is electrically connected to the power supply. Multiple function switches 500 are arranged around the coil 400 to realize multiple functions of the wireless charging device 10. The top cover 300 has multiple spaced-apart isolation slots 311, and each function switch 500 is located in a corresponding isolation slot 311 to avoid the metal parts of the function switch 500 from interfering with the signal of the coil 400. Compared with the traditional design where the function buttons are far away from the coil 400, the wireless charging device 10 of this application effectively utilizes the assembly space of the top cover 300 and the bottom shell 200, making the device structure more compact and more conducive to the assembly of the device in smart homes.
[0036] In one embodiment, the function switch 500 is a tactile switch or a touch switch. In this embodiment, the function selection of the wireless charging device 10 is achieved through a tactile switch or a touch switch. Furthermore, in other embodiments, the function switch 500 can also be other switches based on existing technology.
[0037] In one embodiment, the function switch 500 is a tactile switch;
[0038] The function switch 500 includes a conductive elastic element (not shown) and a button (not shown). One end of the conductive elastic element is connected to the circuit board 100, and the other end of the conductive elastic element is connected to the button. The conductive elastic element and the button are located in the clearance and blocking groove 311, and the button is flush with the surface of the upper cover 300.
[0039] In this embodiment, the function switch 500 is a tactile switch, and the conductive elastic element is a metal sheet. Pressing the button causes the metal sheet to deform under force, thereby closing or opening the circuit and enabling the selection of the function of the wireless charging device 10. Furthermore, both the button and the conductive elastic element are located within the clearance groove 311 to prevent the conductive elastic element from interfering with the electromagnetic waves of the coil 400. At the same time, the button is flush with the surface of the top cover 300 to ensure a flat surface for the wireless charging device 10.
[0040] In one embodiment, the height of the clearance groove 311 is greater than the height of the conductive elastic element. It is understood that the greater height of the clearance groove 311 ensures that the conductive elastic element is completely contained within the clearance groove 311, further improving the shielding effect of the top cover 300 on the conductive elastic element.
[0041] In one embodiment, the top cover 300 is a glass top cover 300. In this embodiment, the top cover 300 is made of glass to make the structure of the top cover 300 flat, and at the same time to make the wireless charging device 10 more aesthetically pleasing.
[0042] In one embodiment, a heat-dissipating protective film (not shown) is attached to the surface of the top cover 300. It is understood that heat is generated when the coil 400 is energized, and this heat is transferred to the top cover 300. Since the top cover 300 is in contact with the charging device, heat is transferred from the top cover 300 to the charging device. By attaching a heat-dissipating protective film made of polyimide (PI) to the surface of the top cover 300, the heat dissipation performance of the top cover 300 is improved, and it also provides waterproofing, thereby extending the lifespan of the device.
[0043] like Figure 3 As shown, in one embodiment, the upper cover 300 has a plurality of spaced-apart limiting posts 310 protruding on one side adjacent to the bottom shell 200, and each limiting post has a corresponding clearance groove 311. In this embodiment, the upper cover 300 has a plurality of spaced-apart limiting posts 310 protruding on one side adjacent to the bottom shell 200, and each limiting post 310 has a corresponding clearance groove 311. The multiple function switches 500 are located in the corresponding clearance grooves 311. This saves material on the upper cover 300 and also prevents the metal pieces of the function switches 500 from interfering with the coil 400.
[0044] like Figure 1 , Figure 4 and Figure 5As shown, in one embodiment, the bottom shell 200 includes a first shell 210 and a second shell 220 connected in sequence. The first shell 210 has a first embedding groove 211, and the second shell 220 has a second embedding groove 221. The first embedding groove 211 and the second embedding groove 221 are connected. The upper cover 300 is located in the first embedding groove 211, and the circuit board 100 is located in the second embedding groove 221. The groove wall of the second embedding groove 221 has a clearance opening 222 for wires to pass through. In this embodiment, the first shell 210 and the second shell 220 are integrally formed, and the upper cover 300 is located in the first embedding groove 211 to make the upper cover 300 and the bottom shell 200 structurally flat. The circuit board 100 is located in the second embedding groove 221 and connected to the second shell 220. Wires are connected to the circuit board 100 through the clearance opening 222 to make the circuit board 100 conductive to the power supply.
[0045] like Figure 5 As shown, in one embodiment, the diameter of the first housing 210 is larger than the diameter of the second housing 220. It is understood that the diameter of the first housing 210 is larger than the diameter of the second housing 220 so that the first housing 210 and the second housing 220 form a "T" shape to fit the furniture assembly space, resulting in a flat structure for the assembled wireless charging device 10.
[0046] This application also provides a smart home system, including the wireless charging device 10 described in any of the above embodiments, wherein the wireless charging device 10 is used to install on a sofa or table. The aforementioned wireless charging device 10, through its compact and miniaturized structural design, enables the wireless charging device to perform multiple functions and is also adaptable to the assembly space of a smart home, thereby improving the convenience of charging electrical devices.
[0047] Compared with the prior art, this disclosure has at least the following advantages:
[0048] In the aforementioned wireless charging device 10, the circuit board 100 is mounted on the bottom shell 200, the coil 400 is electrically connected to the circuit board 100, and the circuit board 100 is electrically connected to the power supply. Multiple function switches 500 are arranged around the coil 400 to realize multiple functions of the wireless charging device 10. The top cover 300 has multiple spaced-apart isolation slots 311, and each function switch 500 is located in a corresponding isolation slot 311 to avoid the metal parts of the function switch 500 from interfering with the signal of the coil 400. Compared with the traditional design where the function buttons are far away from the coil 400, the wireless charging device 10 of this application effectively utilizes the assembly space of the top cover 300 and the bottom shell 200, making the device structure more compact and more conducive to the assembly of the device in smart homes.
[0049] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure.
