[0033] This embodiment provides a wireless charging kit, which can be applied to a mobile terminal. The wireless charging kit may include a housing, a receiving coil and a connector. The receiving coil and the connector may be arranged on the housing. The receiving coil is electrically connected to the connector.

[0034] When the wireless charging kit is installed on the mobile terminal, the connector of the wireless charging kit is electrically connected to the wireless charging circuit of the mobile terminal, so that the receiving coil of the wireless charging kit is electrically connected to the wireless charging circuit of the mobile terminal. In addition, the receiving coil of the wireless charging kit and the receiving coil of the mobile terminal are connected in parallel. That is, when the wireless charging kit is installed on the mobile terminal, the receiving coils included in both the wireless charging kit and the mobile terminal are connected in parallel.

[0035] In one embodiment, the housing of the wireless charging kit may include a housing base. Figure 1 When the wireless charging kit is installed on the mobile terminal, the housing base 11 can be used to accommodate the mobile terminal 200. At least two receiving coils can be provided on the housing base 11. The at least two receiving coils are arranged side by side and at intervals.

[0036] Take the case where two receiving coils are provided on the housing base 11 as an example. Figure 2 As shown, a receiving coil 21 and a receiving coil 22 are provided on the housing base 11 , and the receiving coil 21 and the receiving coil 22 are arranged side by side and spaced apart from each other.

[0037] In one embodiment, in addition to the shell base, the housing of the wireless charging kit may also include a cover. The cover is connected to the shell base. The cover can cover the screen of the mobile terminal. That is, the user can flip open or retract the cover. When the user retracts the cover, the cover can block the screen of the mobile terminal. When the user flips open the cover, the cover will not block the screen of the mobile terminal. The cover may be provided with a receiving coil. The receiving coil of the cover, the receiving coil of the shell base, and the receiving coil of the mobile terminal are connected in parallel.

[0038] In one embodiment, at least two receiving coils may be provided on the cover of the wireless charging kit. The at least two receiving coils may be arranged side by side and spaced apart from each other. For example, two receiving coils may be provided on the cover. Figure 3 As shown, the wireless charging kit may include a housing base 11 and a cover 12. The cover 12 may be provided with a receiving coil 23 and a receiving coil 24. The receiving coil 23 and the receiving coil 24 are arranged side by side and spaced from each other.

[0039] In another embodiment, the cover of the wireless charging kit may be provided with at least two receiving coils. The at least two receiving coils may be coaxially arranged and spaced apart from each other. For example, two receiving coils are provided on the cover. Figure 4 As shown, the cover 12 may be provided with a receiving coil 25 and a receiving coil 26. The receiving coil 25 and the receiving coil 26 are coaxially arranged and spaced from each other. It should be noted that the size of the receiving coil 25 may be consistent with that of the receiving coil 26.

[0040] In one embodiment, the housing of the wireless charging kit may include a housing base and a cover. The cover is connected to the housing base. When the wireless charging kit is installed on a mobile terminal, the housing base can be used to accommodate the mobile terminal. The cover can cover the screen of the mobile terminal. That is, the user can flip open or retract the cover. When the user retracts the cover, the cover can block the screen of the mobile terminal. When the user flips open the cover, the cover will not block the screen of the mobile terminal. The cover may be provided with a receiving coil. The receiving coil of the cover and the receiving coil of the mobile terminal are connected in parallel.

[0041] In one embodiment, at least two receiving coils may be provided on the cover of the wireless charging kit. The at least two receiving coils may be arranged side by side and spaced apart from each other. For example, two receiving coils may be provided on the cover. Figure 5 As shown, the wireless charging kit may include a housing base 11 and a cover 12. The cover 12 may be provided with a receiving coil 23 and a receiving coil 24. The receiving coil 23 and the receiving coil 24 are arranged side by side and spaced from each other. However, no receiving coil is provided on the housing base 11.

[0042] In another embodiment, the cover of the wireless charging kit may be provided with at least two receiving coils. The at least two receiving coils may be coaxially arranged and spaced apart from each other. For example, two receiving coils are provided on the cover. Figure 6 As shown, the cover body 12 may be provided with a receiving coil 25 and a receiving coil 26. The receiving coil 25 and the receiving coil 26 are coaxially arranged and spaced from each other. However, no receiving coil is provided on the housing base 11.

[0043] In one embodiment, the cover body is provided with two receiving coils as an example. Figure 7 The cover body 12 is provided with a first receiving coil 27 and a second receiving coil 28. The first receiving coil 27 and the second receiving coil 28 are coaxially arranged and spaced from each other. A magnetic shielding layer 41 may also be provided between the first receiving coil 27 and the second receiving coil 28.

[0044] This embodiment also provides a wireless charging base, such as Figure 7 As shown, the wireless charging base 300 may include a first side wall 301, a second side wall 302 and a third side wall 303. The first side wall 301, the second side wall 302 and the third side wall 303 form a receiving groove 304. A first transmitting coil 305 is provided on the first side wall 301, and a second transmitting coil 306 is provided on the second side wall 302.

[0045] When the cover 12 is located in the receiving groove 304 of the wireless charging base 300, for example, when the user flips open the cover 12 and places the cover 12 in the receiving groove 304, the first receiving coil 27 can receive power from the first transmitting coil 305, and the second receiving coil 28 can receive power from the second transmitting coil 306. After receiving power, the first receiving coil 27 and the second receiving coil 28 can wirelessly charge the mobile terminal through the wireless charging circuit of the mobile terminal.

[0046] It is understandable that when the cover 12 is located in the receiving groove 304, the charging speed of the mobile terminal can be improved because the first receiving coil 27 and the second receiving coil 28 can receive power at the same time. In addition, since the first receiving coil 27 and the second receiving coil 28 are connected in parallel, the charging power can be evenly distributed.

[0047] In another implementation, this embodiment further provides a wireless charging base, wherein the transmitting coils of the wireless charging base are arranged on the same side. Figure 8 The wireless charging base 300 may be provided with at least a transmitting coil 307 and a transmitting coil 308. The transmitting coil 307 and the transmitting coil 308 are provided on the same side. For example, the transmitting coil 301 and the transmitting coil 308 are both provided on one side of the surface 310 of the wireless charging base 300.

[0048] Then, when the cover 12 is located on the wireless charging base 300, the receiving coil of the cover 12 that is close to the wireless charging base (i.e., the target receiving coil) receives power from the transmitting coil of the wireless charging base. The target receiving coil is one of the first receiving coil 27 and the second receiving coil 28 of the cover.

[0049] For example, when the user places the screen of the mobile terminal upward and opens the cover, the second receiving coil 28 of the cover 12 is close to the transmitting coil 307 of the wireless charging base. Then, the second receiving coil 28 will receive power from the transmitting coil 307, that is, the second receiving coil 28 is the target receiving coil. Alternatively, when the user places the screen of the mobile terminal downward and opens the cover, the first receiving coil 27 of the cover is close to the transmitting coil 307 of the wireless charging base. Then, the first receiving coil 27 will receive power from the transmitting coil 307, that is, the first receiving coil 27 is the target receiving coil.

[0050] In one embodiment, the housing of the wireless charging kit may include a cover and a housing base. The cover is connected to the housing base. When the wireless charging kit is installed on a mobile terminal, the housing base is used to accommodate the mobile terminal, and the cover can cover the screen of the mobile terminal. The cover and the housing base are each provided with at least one receiving coil.

[0051] When the cover covers the screen of the mobile terminal and the wireless charging kit is located in the receiving slot of the wireless charging base, the receiving coils of the cover and the shell base respectively receive electrical energy from the transmitting coil of the wireless charging base, wherein the transmitting coils are provided on two side walls of the receiving slot of the wireless charging base.

[0052] For example, Fig. 9 As shown, the wireless charging base 300 includes a first side wall 301, a second side wall 302 and a third side wall 303. The first side wall 301, the second side wall 302 and the third side wall 303 form a receiving groove. A transmitting coil 305 is provided on the first side wall 301, and a transmitting coil 306 is provided on the second side wall 302.

[0053] A receiving coil 291 is provided at the cover of the wireless charging kit, and a receiving coil 292 is provided at the shell base of the wireless charging kit. When the wireless charging kit is installed on the mobile terminal 200, when the cover covers the screen of the mobile terminal 200 and the wireless charging kit is located in the receiving slot of the wireless charging base, the receiving coil 291 of the cover and the receiving coil 292 of the shell base receive power from the transmitting coil 305 and the transmitting coil 306 of the wireless charging base respectively.

[0054] In one embodiment, the connector of the wireless charging kit may include a first connector and a second connector. The positive pole of the receiving coil of the wireless charging kit is connected to the first connector, and the negative pole of the receiving coil of the wireless charging kit is connected to the second connector. The first connector may be electrically connected to the positive pole of the wireless charging circuit of the mobile terminal, and the second connector may be electrically connected to the negative pole of the wireless charging circuit of the mobile terminal.

[0057] The mobile terminal 200 may include a housing 204, on which a third connection portion 202 and a fourth connection portion 203 may be provided. The third connection portion 202 is electrically connected to the positive pole of the wireless charging circuit of the mobile terminal 200, and the fourth connection portion 203 is electrically connected to the negative pole of the wireless charging circuit of the mobile terminal 200. The mobile terminal 200 also includes a receiving coil 201 and a magnetic shielding layer 43.

In addition, each receiving coil on the wireless charging kit and the receiving coil of the mobile terminal are connected in parallel with each other. That is, the first receiving coil 27, the second receiving coil 28, the receiving coil 293 of the housing base 11, and the receiving coil 201 of the mobile terminal 200 are arranged in parallel with each other.

[0059] In another embodiment, if Fig.11 As shown, a notch may be provided on the housing 204 of the mobile terminal 200, and the third connection portion 202 and the fourth connection portion 204 may be provided in the notch.
