[0007] Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The referenced element symbols in the following description will be regarded as the same or similar elements when the same element symbols appear in different drawings. These embodiments are only part of the present invention and do not disclose all possible implementation methods of the present invention. More specifically, these embodiments are only examples within the scope of the patent application of the present invention.

[0008] Please refer to FIG. 1, which is a schematic diagram of a portable electronic device according to an embodiment of the present invention. FIG. 1 shows a circuit diagram and a configuration diagram of a portable electronic device 100. In this embodiment, the portable electronic device 100 includes a function panel 110 and a host 120. The function panel 110 includes panel coils CP1-CP6. The host 120 is connected to the panel coils CP1-CP6. The host 120 includes a host coil CH and a battery module 121. The battery module 121 is connected to the host coil CH and the panel coils CP1-CP6.

[0009] In this embodiment, when the function panel 110 is overlapped with the host 120, the host 120 provides one of the battery power PB of the battery module 121 and the host coil power PH from the host coil CH to the panel coils CP1-CP6. Therefore, the function panel 110 can use the power located in the panel coils CP1-CP6 to perform one of wireless power transmission and induction heating (IH).

[0010] It is worth mentioning that the electric energy in the panel coils CP1-CP6 can be used for either wireless power transmission or induction heating. In this way, the portable electronic device 100 has multiple wireless power coupling functions.

[0011] In this embodiment, the host coil CH is located at the edge of the host 120. The area surrounded by the host coil CH is larger than the area surrounded by the panel coils CP1-CP6. In addition, when the functional panel 110 is overlapped with the host 120, the area surrounded by the panel coils CP1-CP6 will be within the area surrounded by the host coil CH.

[0012] For example, the functional panel 110 may be a display panel. The panel coils CP1-CP6 are disposed in the back panel 111 of the functional panel 110. For example, the portable electronic device 100 may be a notebook computer.

[0013] In this embodiment, the functional panel 110 includes six panel coils CP1 to CP6. However, the present invention is not limited to the number of panel coils. The functional panel 110 may include one or more panel coils.

[0014] In this embodiment, the battery module 121 can be implemented by an aluminum ion battery module, but the present invention is not limited to the implementation of the battery module 121.

[0015] In addition, in the present embodiment, the host 120 can adjust at least one of the frequency and amplitude of the electric energy located in the panel coils CP1~CP6, thereby adjusting the transmission directivity of the wireless power transmission. Specifically, the panel coils CP1~CP6 are regarded as a panel coil array. The difference in the frequency and amplitude of the electric energy located in the panel coils CP1~CP6 can affect the direction in which the functional panel 110 performs one of wireless power transmission and induction heating. For example, when the electric energy located in the panel coil CP1 has the maximum amplitude, the power supply direction of the functional panel 110 will be toward an object adjacent to or close to the panel coil CP1. When the electric energy located in the panel coils CP1 and CP6 have the same maximum amplitude, the power supply direction of the functional panel 110 will be toward at least one object adjacent to or close to the panel coils CP1 and CP6.

[0016] Please refer to FIG. 1 and FIG. 2 , FIG. 2 is a schematic diagram of the operation of a portable electronic device according to an embodiment of the present invention. In this embodiment, wireless power transmission may include wireless charging. For example, when the functional panel 110 is overlapped with the host 120, the external portable electronic devices ED1 and ED2 are placed on the back plate 111. The position of the external portable electronic device ED1 corresponds to the panel coil CP1. The position of the external portable electronic device ED2 corresponds to the panel coil CP5. Therefore, the power located in the panel coil CP1 can be used to wirelessly charge the external portable electronic device ED1. The power located in the panel coil CP5 can be used to wirelessly charge the external portable electronic device ED2. The external portable electronic devices ED1 and ED2 can be a smart phone and a smart watch, respectively. The external portable electronic device ED1 receives the power located in the panel coil CP1 in a wireless power transmission manner to charge the battery (not shown) in the external portable electronic device ED1. The external portable electronic device ED2 receives power from the panel coil CP5 via wireless power transmission to charge a battery (not shown) in the external portable electronic device ED2.

[0017] For example, when the function panel 110 is overlapped with the host 120, the conductive object CT1 is placed on the back plate 111. The position of the conductive object CT1 corresponds to the panel coils CP1, CP2, CP4, CP5. Therefore, the electric energy located in the panel coils CP1, CP2, CP4, CP5 can induction heat the conductive object CT1. The conductive object CT1 can be a metal container. The electric energy located in the panel coils CP1, CP2, CP4, CP5 can generate eddy currents on the surface of the conductive object CT1 and heat the surface of the conductive object CT1. The function panel 110 itself does not generate heat. In this embodiment, when the electric energy located in the panel coils CP1, CP2, CP4, CP5 induction heats the conductive object CT1, the conductive object CT1 can be raised to be close to the panel coils CP1, CP2, CP4, CP5 without contacting the function panel 110.

[0018] In this embodiment, when the function panel 110 is overlapped with the host 120, the host 120 performs one of wireless power transmission and induction heating according to the object type of the object close to the panel coils CP1~CP6. For example, the object adjacent to the panel coil CP1 can communicate with the host 120 through any form of communication to inform the object type. When the host 120 knows that the object is an external portable electronic device ED1 according to the object type of the object and the external portable electronic device ED1 is adjacent to the panel coil CP1, the function panel 110 can use the power located in the panel coil CP1 to perform wireless power transmission to the external portable electronic device ED1.

[0019] For example, when the host 120 knows that the object is a conductive object CT1 according to the object type and the conductive object CT1 is close to the panel coil CP4, the functional panel 110 can use the power located in the panel coil CP4 to inductively heat the conductive object CT1. In addition, the functional panel 110 can also use the power of the panel coils CP1, CP2, and CP5 located adjacent to the panel coil CP4 to inductively heat the conductive object CT1.

[0020] For example, the user may set the portable electronic device 100 according to the object type of the object, so that the functional panel 110 utilizes the power located in the panel coils CP1-CP6 to perform one of wireless power transmission and induction heating.

[0021] In this embodiment, when the host 120 learns that the object is a conductive object CT1 according to the object type and the conductive object CT1 is close to the panel coil CP4, the functional panel 110 uses the electric energy located in the panel coils CP1, CP2, CP4, and CP5 to inductively heat the conductive object CT1. In addition, the host 120 also uses the host coil electric energy PH to inductively heat the conductive object CT1. In this way, the range of inductive heating is increased. In addition, the uniformity of inductive heating can be improved.

[0022] In this embodiment, the host coil power PH can also be provided to the panel coils CP1-CP6 in a wireless power transmission manner. Therefore, the portable electronic device 100 can transmit the host coil power PH to the panel coils CP1-CP6 via the host coil CH to perform one of wireless power transmission and induction heating.

[0023] In this embodiment, the battery power PB can also be provided to the panel coils CP1-CP6 in a wired power transmission manner. Therefore, the battery module 121 can provide the battery power PB to the panel coils CP1-CP6 to perform one of wireless power transmission and induction heating.

[0024] Please refer to FIG. 1 and FIG. 3 , which is a schematic diagram of the operation of a portable electronic device according to an embodiment of the present invention. In this embodiment, when the function panel 110 is overlapped with the host 120 and at least one of the panel coils CP1 to CP6 is adjacent to an external portable electronic device, the function panel 110 can use the at least one of the panel coils CP1 to CP6 to receive external power from the external portable electronic device. For example, when the function panel 110 is overlapped with the host 120, the panel coil CP1 is adjacent to the external portable electronic device ED1. The panel coil CP5 is adjacent to the external portable electronic device ED2. Therefore, the panel coil CP1 receives the external power PE1 from the external portable electronic device ED1 in a wireless power transmission manner. The panel coil CP5 receives the external power PE2 from the external portable electronic device ED2 in a wireless power transmission manner.

[0025] Next, the function panel 110 uses the external power PE1 and PE2 to charge the battery module 121. For example, the host 120 receives the external power PE1 and PE2 from the panel coils CP1 and CP5, and provides the external power PE1 and PE2 to the battery module 121. For another example, the host 120 can use the host coil CH to receive the external power PE1 and PE2 from the panel coils CP1 and CP5 in a wireless power transmission manner to generate the host coil power PH, and provide the host coil power PH to the battery module 121.

[0026] Please refer to FIG. 4, which is a schematic diagram of a portable electronic device according to an embodiment of the present invention. In this embodiment, the portable electronic device 200 includes a function panel 110 and a host 220. The function panel 110 includes panel coils CP1-CP6. The host 220 is connected to the panel coils CP1-CP6. The host 220 includes a host coil CH, a battery module 121, and transmission circuits 222 and 223. The transmission circuit 222 is connected between the battery module 121 and the panel coils CP1-CP6. The transmission circuit 222 transmits the battery power PB to the panel coils CP1-CP6, and transmits the power in the panel coils CP1-CP6 to the battery module 121.

[0027] The transmission circuit 223 is connected between the battery module 121 and the host coil CH. The transmission circuit 223 transmits the battery power PB to the host coil CH, and uses the host coil power PH to charge the battery module 121.

[0028] The host 220 further includes a power regulator 224. The power regulator 224 is connected between the transmission circuit 223 and the battery module 121. The power regulator 224 regulates the host coil power PH to the battery power PB. Therefore, the power regulator 224 can convert the host coil power PH into a voltage value and / or current value that meets the requirements for charging the battery module 121.

[0029] In this embodiment, the host 220 may not include the power regulator 224. In other words, based on different designs or requirements, the power regulator 224 may be omitted.

[0030] In this embodiment, the power transmission between the functional panel 110, the host coil CH and the battery module 121 has been clearly described in the multiple embodiments of FIG. 1 to FIG. 3, and thus will not be repeated here.

[0031] Please refer to FIG. 5 and FIG. 6. FIG. 5 is a schematic diagram of a portable electronic device according to an embodiment of the present invention. FIG. 6 is an operation schematic diagram of a portable electronic device according to an embodiment of the present invention. In this embodiment, the portable electronic device 300 includes a function panel 110, a host 220, and a power circuit 330. The function panel 110 includes panel coils CP1 to CP6. The host 220 is connected to the panel coils CP1 to CP6. The host 220 includes a host coil CH, a battery module 121, transmission circuits 222, 223, and a power regulator 224. The connection method and operation of the transmission circuits 222, 223 and the power regulator 224 have been clearly described in the embodiment of FIG. 4, so they will not be repeated here.

[0032] The power circuit 330 includes a power coil CW and a power transmission circuit 331. The power transmission circuit 331 is connected to the power coil CW. The power transmission circuit 331 transmits the power of the external power source PEX to the power coil CW. The power circuit 330 provides the power power PW located in the power coil CW to at least one of the panel coils CP1~CP6 and the host coil CH in a wireless power transmission manner.

[0033] For example, the host 220 uses the host coil CH to receive the power energy PW located at the power coil CW to generate the host coil power PH, and uses the host coil power PH to charge the battery module 121. For example, the host coil power PH is provided to the battery module 121 via the power regulator 224 and the transmission circuit 223.

[0034] For example, the host 220 uses the host coil CH to receive the power energy PW located in the power coil CW to generate the host coil energy PH, and provides the host coil energy PH to the panel coils CP1-CP6. Therefore, the functional panel 110 can use the energy located in the panel coils CP1-CP6 to perform one of wireless power transmission and induction heating, as shown in FIG6. The operation of wireless power transmission and induction heating has been clearly described in the embodiments of FIG1 and FIG2, so it will not be repeated here.

[0035] For example, the power circuit 330 uses the power coil CW to receive the host coil power PH to generate the power power PW, and provides the power power PW to the panel coils CP1-CP6. Therefore, the functional panel 110 can use the power in the panel coils CP1-CP6 to perform one of wireless power transmission and induction heating.

[0036] In addition, the power circuit 330 can also utilize the power coil CW to receive at least one of the power of the host coil PH and the power of the panel coils CP1-CP6.

[0037] For example, the host 220 provides the battery power PB of the battery module 121 to the host coil CH to generate the host coil power PH. The power circuit 330 receives the host coil power PH through the power coil CW to generate the power power PW, and feeds the power power PW in the power coil CW back to the external power PEX.

[0038] For example, the functional panel 110 provides the power (e.g., external power PE1, PE2) located in the panel coils CP1-CP6 to the host coil CH to generate the host coil power PH. The power circuit 330 uses the power coil CW to receive the host coil power PH to generate the power power PW, and uses the power power PW located in the power coil CW to feed back to the external power PEX.

[0039] For example, the functional panel 110 provides the power (e.g., external power PE1, PE2) located in the panel coils CP1-CP6 to the power coil CW to generate power power PW. The power circuit 330 uses the power coil CW to receive the host coil power PH to generate power power PW, and uses the power power PW located in the power coil CW to feed back to the external power PEX.

[0040] In this embodiment, the external power source PEX comes from the power grid. Therefore, the power circuit 330 can use the power coil CW to collect at least one of the power of the host coil PH and the power of the panel coils CP1-CP6 to generate power energy PW, and use the power energy PW in the power coil CW to feed back to the power grid.

[0041] Based on the above, the portable electronic device 300 realizes a variety of wireless power transmission functions.

[0043] In this embodiment, when the switch SW1 is turned on, the panel coil CP1 is selected. At this time, the capacitor C1 and the panel coil CP1 perform a resonant operation. Therefore, the resonant frequency of the electric energy in the panel coil CP1 is equal to the preset wireless power transmission frequency. Therefore, the electric energy in the panel coil CP1 has a better power transmission efficiency. On the other hand, when the switch SW1 is turned off, the panel coil CP1 is not selected.
