Example Embodiment

[0053] Example one

[0054] reference image 3 , The wireless transmitting part 10 includes a transmitting coil 11 and a first ferrite 10. The first ferrite 10 is arranged below the transmitting coil 11, and the first ferrite 10 connects the transmitting coil 11 with other metals in the wireless charging device. The devices are spaced apart, and the first ferrite 10 is used to prevent metal devices provided in the wireless charging device from affecting the transmitter coil 11 to generate magnetic flux. The relay part 30 includes a relay coil 31 and a circuit part. The circuit part includes a capacitor 32. The two ends of the capacitor 32 are connected with both ends of the relay coil 31 to form a loop. The entire relay part 30 is located above the transmitting coil 11. The wireless receiving part 20 includes a receiving coil 202 and a second ferrite 203. The wireless receiving part 20 is set in the device to be charged. The device to be charged includes a battery 204. The second...

Example Embodiment

[0061] Example two

[0062] This embodiment is an improvement made on the basis of the first embodiment. In this example, the wireless transmitting part 10 includes two transmitting coils, such as Picture 9 Shown. The two transmitting coils are the first transmitting coil 111 and the second transmitting coil 112 respectively, and the first transmitting coil 111 and the second transmitting coil 112 are arranged side by side above the first ferrite 12. The relay coil 31 is located above the middle of the first transmission coil 111 and the second transmission coil 112. In this embodiment, as Picture 10 As shown, the circuit part 33 connected to both ends of the relay coil 31 is provided with a switch 34 and a control part 35 in addition to the capacitor 32. In this example, the relay coil 31 has a dual function, which can be used as a spare transmitter coil, or can realize the function of a transmitter coil alone. Except for the above improvements, the rest of this embodiment i...

Example Embodiment

[0068] Example three

[0069] This embodiment is an improvement made on the basis of the first and second embodiments, such as Picture 11 As shown, the present example includes two relay parts and one transmitting coil, and each relay part includes the circuit part as described in the second embodiment, and the transmitting coil 11 is located below the middle of the two relay coils 31, The relay coil has the dual functions of the transmitting coil and the relay coil at the same time, which is selected by the circuit section 33. Except for the above improvements, the rest of this embodiment is the same as the first embodiment. This embodiment realizes free charging in more locations.

[0070] The working principle of this embodiment is as follows:

[0071] reference Picture 11 , When the position of the receiving coil is above the transmitting coil 11, such as Picture 11 Above the position A shown in Figure 1, the transmitting coil 11 receives the current from the signal source, ...

Abstract

The invention provides an enhanced wireless charging system, which comprises a wireless emitting part, at least one relay part, and a wireless receiving part, wherein the wireless emitting part comprises a first ferrite and at least one emitting coil, and the emitting coil is connected with a signal source; the relay part comprises a relay coil and a circuit part, and two ends of the relay coil and two ends of the circuit part form a return circuit; and the wireless receiving part comprises a receiving coil and a second ferrite. According to the system, a first coil is powered on to produce a first magnetic flow passing through the relay coil; the relay coil produces a first induced current; the circuit part conducts charging and discharging, so as to allow the relay coil to produce a second magnetic flux; and the second magnetic flux passes through the receiving coil, so that the receiving coil obtains energy to charge a battery. Through the adoption of the system, the relay coil and a capacitor are introduced, the charging distance increasing can be realized through the increment of the magnetic flow of the receiving coil; the ferrite is thinner to save space so as to realize the application of thinner mobile phones and other terminals; and additionally, a control part is introduced, and the relay coil or the emitting coil is increased, so as to realize charging at free position.

Description

[0001] technical field [0002] The invention relates to the technical field of design of mobile phone charging systems, in particular to an enhanced wireless charging system. [0003] Background technique [0004] Wireless terminals, such as PDA (Persional Digital Assistant), mobile phones and other power supplies are provided by a rechargeable battery. The existing charging methods include: an independent battery charging base, charging through a USB universal interface and wireless charging. The stand-alone battery charging base method requires at least two batteries, and the batteries do not work during charging. Charging through the USB universal interface requires only one battery, and the battery is in continuous working state during charging, but requires a USB connection. Wireless charging enables a battery to be charged at any time without any connecting wires. [0005] In recent years, the technology of wireless charging has developed rapidly and is rapidly ap...
