[0019] In order to fully understand the present application, a detailed structure will be provided in the following description to illustrate the technical solution proposed in the present application. The preferred embodiments of the present application are described in detail below. However, in addition to these detailed descriptions, the present application may also have other implementation methods.

[0020] The following describes a wireless charging device 100 according to one embodiment of the present application with reference to Figures 1 to 6. As shown in Figures 1 to 6, the wireless charging device 100 includes: a charging device body; a magnetic wireless charging transmitter module 110 for attracting and wirelessly charging electronic devices; wherein, the number of magnetic wireless charging transmitter modules 110 is multiple, and any one of the multiple magnetic wireless charging transmitter modules 100 is detachably connected to the charging device body.

[0021] In one example, the electronic device can be attracted to the magnetic wireless charging transmitter module 110 by magnetic force, and the magnetic wireless charging transmitter module 110 can wirelessly charge the electronic device.

[0022] In one example, since there are multiple magnetic wireless charging transmitter modules 110, any one of the multiple magnetic wireless charging transmitter modules 110 can be detachably connected to the charging device body, so different magnetic wireless charging transmitter modules 110 can be replaced and assembled with the charging device body to meet different charging needs.

[0023] In one example, the wireless charging method of the magnetic wireless charging transmitting module 110 can be electromagnetic induction, magnetic field resonance, radio wave, or other types, which are not limited to this.

[0024] In one example, the wireless charging standard of the magnetic wireless charging transmitting module 110 can be Qi standard, Power Matters Alliance (PMA) standard, Alliance for Wireless Power (A4WP) standard, iNPOFi technology, Wi-Po technology, or other standards, which are not limited to this.

[0025] In one example, the electronic device may be a mobile phone, a tablet, a smart watch, a headset, etc., which is not limited to this. For example, FIG1 shows a schematic diagram of a mobile phone 200 being attached to a wireless charging device 100 .

[0026] According to the wireless charging device 100 of the present application, by making any one of the multiple magnetic wireless charging transmitter modules 110 detachably connected to the charging device body, different magnetic wireless charging transmitter modules 110 can be replaced and assembled with the charging device body according to actual charging needs, so that the wireless charging device 100 can meet different charging needs.

[0027] In one embodiment of the present application, the plurality of magnetic wireless charging transmitter modules 110 may each have different charging powers, or may each have other different charging functions, etc., without limitation. Thus, magnetic wireless charging transmitter modules 110 with different charging powers and different charging functions can be replaced and assembled with the charging device body, so that the wireless charging device 100 can provide different charging powers and different charging functions.

[0028] In one embodiment of the present application, as shown in Figure 1, the magnetic wireless charging transmitter module 110 is tilted relative to the main body of the charging device. After the electronic device is attached to the magnetic wireless charging transmitter module 110, it can be placed at an angle, acting as a stand, so that wireless charging does not affect the use of the electronic device.

[0029] In one embodiment of the present application, as shown in FIG. 2 , the magnetic wireless charging transmitter module 110 includes a magnetic wireless charging transmitter module 111 and a bracket 112 provided on the magnetic wireless charging transmitter module 111 .

[0030] In one embodiment of the present application, as shown in FIG2 , a slot 113 is formed between the magnetic wireless charging transmitter module 111 and the bracket 112. The magnetic wireless charging transmitter module 111 can be mounted in other locations through the slot 113. The other locations may be a desktop, a vehicle cabin, a selfie device, or other electronic devices, without limitation.

[0031] In one example, the magnetic wireless charging transmitter module 110 can serve as a bracket for an electronic device. After the electronic device is adsorbed onto the magnetic wireless charging transmitter module 110, the magnetic wireless charging transmitter module 110 can be clamped on other electronic devices through the card slot 113, so that the wireless charging device 100 can also have the function of an electronic device bracket.

[0032] For example, as shown in Figure 3, taking the electronic device as a mobile phone 200 as an example, the magnetic wireless charging transmitter module 110 can be used as a mobile phone holder. After the mobile phone 200 is adsorbed on the magnetic wireless charging transmitter module 110, the magnetic wireless charging transmitter module 110 can be clamped on the edge of the screen of the laptop computer 300 through the card slot 113, so that the mobile phone camera can act as the camera of the laptop computer 300.

[0033] Of course, the mobile phone 200 and the laptop computer 300 can be connected via corresponding software to achieve data transmission. For example, after the mobile phone 200 is inserted into the laptop computer 300 via the card slot 113 of the magnetic wireless charging transmitter module 110, software such as DroidCam or iVcam can be used to establish a communication connection between the mobile phone 200 and the laptop computer 300, thereby allowing the camera of the mobile phone 200 to act as the camera of the laptop computer 300 for applications such as video conferencing and live broadcasting.

[0034] It can be understood that since the magnetic wireless charging transmitter module 110 with different charging power and functions can be replaced, the structure of the magnetic wireless charging transmitter module 111 can be determined according to the actual charging power and function. This application does not specifically limit the structure of the magnetic wireless charging transmitter module 111.

[0035] In one example, as shown in Figure 4, the magnetic wireless charging transmitter module 111 includes a first shell 1111, and a first magnetic member 1112, a wireless charging transmitter coil 1113 and a first circuit board 1114 arranged in the first shell 1111. The wireless charging transmitter coil 1113 is electrically connected to the first circuit board 1114, and the first circuit board 1114 is provided with a first electrical connector 1115 for electrically connecting to the charging device body.

[0036] The first magnetic member 1112 can provide a magnetic force to adsorb the electronic device onto the first housing 1111. Since the electronic device is adsorbed onto the first housing 1111 under the action of the magnetic force, the electronic device can be rotated after being adsorbed onto the first housing 1111 to freely adjust the display angle of the electronic device.

[0037] After the magnetic wireless charging transmitter module 110 is assembled with the charging device body, the magnetic wireless charging transmitter module 110 can be electrically connected to the charging device body through the first electrical connector 1115 .

[0038] After the magnetic wireless charging transmitter module 110 is electrically connected to the charging device body, the power provided by the charging device body can be transmitted to the first circuit board 1114 through the first electrical connector 1115. The first circuit board 1114 can control the wireless charging transmitter coil 1113, which transmits power in the form of electromagnetic waves to the electronic device attached to the first housing 1111, thereby wirelessly charging the electronic device.

[0039] In one example, the first circuit board 1114 can be a PCB (Printed circuit board), PCBA (Printed Circuit Board Assembly, a blank PCB board with SMT components or DIP plug-in), etc., without limitation.

[0040] In one embodiment of the present application, the main body of the charging device is a signal converter module 120 , and the signal converter module 120 is used to supply the received electric energy to the magnetic wireless charging transmitting module 110 .

[0041] In one example, the signal converter module 120 has a signal conversion function. For example, it can duplicate or even expand the ports of the laptop computer 300 to enable convenient one-stop connection between the laptop computer 300 and multiple accessories or external devices, thereby increasing the number and types of output interfaces of the laptop computer 300.

[0042] In one example, since the signal converter module 120 and the magnetic wireless charging transmitter module 110 are detachably connected, the signal converter module 120 with different signal conversion functions can be replaced according to actual signal conversion requirements.

[0043] In one example, the signal converter module 120 can be connected to a laptop computer 300 , a desktop computer, or other devices. The signal converter module 120 can obtain electrical energy from the above devices and provide the obtained electrical energy to the magnetic wireless charging transmitter module 110 .

[0044] In one example, the electronic device can be adsorbed onto the magnetic wireless charging transmitter module 110, and the magnetic wireless charging transmitter module 110 can send the power provided to it by the signal converter module 120 to the electronic device through wireless charging, thereby wirelessly charging the electronic device.

[0045] Thus, the wireless charging device 100 of this embodiment, by combining the magnetic wireless charging transmitter module 110 with the signal converter module 120, not only enables wireless charging but also functions as a signal converter. This allows for multiple functions, reduces the number of desktop accessories, tidies up the desktop, and reduces the cost of purchasing various accessories. Furthermore, this embodiment allows for replacement of the signal converter module 120 with different signal conversion functions based on signal conversion requirements.

[0046] In one embodiment of the present application, as shown in FIG. 5 , the signal converter module 120 includes a signal converter body 121 and a control module 122 disposed on the signal converter body 121 for controlling the magnetic wireless charging transmitter module 110 .

[0047] The signal converter body 121 is a device that can convert one signal into another. For example, the signal converter body 121 can duplicate or even expand the ports of a notebook computer, thereby enabling convenient one-stop connection between the notebook computer 300 and multiple accessories or external devices, thereby increasing the number and types of output interfaces of the notebook computer 300.

[0048] It is understandable that since the signal converter module 120 with different signal conversion functions can be replaced, the structure of the signal converter body 121 can be determined according to the actual signal conversion function. This application does not specifically limit the structure of the signal converter body 121.

[0049] In one example, the signal converter body 121 can be a hub, a docking station, an adapter, etc., which is not limited.

[0050] In one example, the signal converter body 121 has one or more signal conversion interfaces for performing signal conversion. The signal conversion interface may be a USB interface (e.g., a Standard type-A interface, a Mini type-A interface, a Micro type-A interface, a Standard type-B interface, a Mini type-B interface, a Micro type-B interface, a type-C interface, etc.), an HDMI interface, a VGA interface, etc., without limitation.

[0051] It should be noted that when the magnetic wireless charging transmitter module 110 performs wireless charging, the first circuit board 1114 can play a primary control role, and the control module 122 can play an auxiliary control role. It is understood that the structure of the control module 122 can also be determined according to actual conditions, and this application does not specifically limit the structure of the control module 122.

[0052] In one example, as shown in Figure 6, the control module 122 includes a second shell 1221, and a third magnetic member 1222 and a second circuit board 1223 arranged in the second shell 1221. The second circuit board 1223 is electrically connected to the signal converter body 121, and the second circuit board 1223 is provided with a second electrical connector 1224 for electrically connecting to the magnetic wireless charging transmitter module 110.

[0053] After the magnetic wireless charging transmitter module 110 and the signal converter module 120 are assembled, the signal converter module 120 can be electrically connected to the magnetic wireless charging transmitter module 110 through the second electrical connector 1224 .

[0054] After the signal converter module 120 is electrically connected to the magnetic wireless charging transmitter module 110, the electric energy received by the signal converter body 121 can be transmitted to the second circuit board 1223, and the second circuit board 1223 then provides the electric energy to the magnetic wireless charging transmitter module 110 through the second electrical connector 1224, so that the magnetic wireless charging transmitter module 110 can wirelessly charge the electronic device adsorbed thereon.

[0055] In one example, the second circuit board 1223 can be a PCB (Printed circuit board), PCBA (Printed Circuit Board Assembly, a blank PCB board with SMT components or DIP plug-in), etc., without limitation.

[0056] In one embodiment of the present application, as shown in FIG. 4 , the bracket 112 is provided with a second magnetic member 114 for magnetically connecting to the signal converter module 120 .

[0057] Among them, after the magnetic wireless charging transmitter module 110 is assembled with the signal converter module 120 through the first coupling part 1121, the assembly between the signal converter module 120 and the magnetic wireless charging transmitter module 110 can be made more stable through the magnetic attraction force between the second magnetic part 114 and the second magnetic part 114.

[0058] In one embodiment of the present application, as shown in FIG. 4 , the bracket 112 has a first coupling portion 1121 detachably connected to the charging device body (eg, the signal converter module 120 ), and the first electrical connector 1115 is exposed at the first coupling portion 1121 .

[0059] Exemplarily, the magnetic wireless charging transmitter module 110 can be assembled with the signal converter module 120 through the first coupling portion 1121, and after the magnetic wireless charging transmitter module 110 and the signal converter module 120 are assembled, the magnetic wireless charging transmitter module 110 and the signal converter module 120 can be electrically connected through the first electrical connector 1115 exposed to the first coupling portion 1121.

[0060] In one embodiment of the present application, as shown in FIG6 , the second shell 1221 has a second coupling portion 1225 detachably connected to the magnetic wireless charging transmitter module 110 , and the second electrical connector 1224 is exposed at the second coupling portion 1225 .

[0061] Exemplarily, the signal converter module 120 can be assembled with the magnetic wireless charging transmitter module 110 through the second coupling portion 1225, and after the signal converter module 120 and the magnetic wireless charging transmitter module 110 are assembled, the signal converter module 120 and the magnetic wireless charging transmitter module 110 can be electrically connected through the second electrical connector 1224 exposed to the second coupling portion 1225.

[0062] Therefore, by exposing the first electrical connector 1115 to the first coupling portion 1121 and the second electrical connector 1224 to the second coupling portion 1225, after the magnetic wireless charging transmitter module 110 and the signal converter module 120 are assembled through the first coupling portion 1121 and the second coupling portion 1225, electrical connection can be achieved through the first electrical connector 1115 exposed in the first coupling portion 1121 and the second electrical connector 1224 exposed in the second coupling portion 1225.

[0063] It is understood that the first coupling portion 1121 and the second coupling portion 1225 can be a detachable mechanical connection structure, such as a snap connection structure, a threaded connection structure, a key connection structure, etc., and this is not limited. For example, as shown in Figures 4 and 6, the first coupling portion 1121 can be a groove structure, and the second coupling portion 1225 can be a protrusion structure that matches the groove structure. The magnetic wireless charging transmitter module 110 and the signal converter module 120 are detachably connected through the groove structure and the protrusion structure. Of course, the first coupling portion 1121 can also be a protrusion structure and the second coupling portion 1225 can be a groove structure, which will not be repeated here.

[0064] The first electrical connector 1115 and the second electrical connector 1224 can be electrical connectors (whose function is to bridge two conductors on a loop so that current or signal can flow from one conductor to another), such as a plug and socket structure, a spring probe structure, etc., which are not limited to this. For example, as shown in Figures 4 and 6, the first electrical connector 1115 can be a pin needle and the second electrical connector 1224 can be a pogo pin needle. After the magnetic wireless charging transmitter module 110 and the signal converter module 120 are assembled, electrical connection is achieved through the pin needle and the pogo pin needle. Of course, the first electrical connector 1115 can also be a pogo pin needle and the second electrical connector 1224 can be a pin needle, which will not be repeated here.

[0065] To summarize, according to the wireless charging device of the embodiment of the present application, by making any one of the multiple magnetic wireless charging transmitter modules detachably connected to the charging device body, different magnetic wireless charging transmitter modules can be replaced and assembled with the charging device body according to actual charging needs, so that the wireless charging device can meet different charging needs, such as different charging power, different charging functions, etc.

[0066] In addition, by combining a magnetic wireless charging transmitter module with a signal converter module, the present invention enables the wireless charging device to function not only as a wireless charger but also as a signal converter. This allows for multiple functions, reduces the number of desktop accessories, tidies up the desktop, and reduces the cost of purchasing various accessories. Furthermore, the present invention allows for replacement of signal converter modules with different signal conversion functions based on signal conversion requirements.
