The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a wireless power transmitting device according to an embodiment of the present invention. As shown in fig. 1, the wireless power transmitting apparatus a includes a wireless power transmitting coil 1 and a magnet unit 2.
The magnet units 2 are arranged around the wireless power transmitting coil 1 at intervals, one end of each magnet unit close to the wireless power transmitting coil 1 and the other end of each magnet unit far away from the wireless power transmitting coil 1 are first magnetic poles 21, and a second magnetic pole 22 is arranged between the two first magnetic poles 21. Wherein the first magnetic pole 21 and the second magnetic pole 22 have opposite polarities. That is, the magnet unit 2 has three magnetic poles arranged in a direction from the center of the wireless power transmitting coil 1 toward the outside of the device, the magnetic poles at both ends have the same polarity, and the magnetic pole in the middle has a polarity opposite to the magnetic poles at both ends. For convenience, the magnetic poles at the two ends are the first magnetic poles 21, and the magnetic pole in the middle is the second magnetic pole 22.
Also, the wireless power transmitting device a has a transmitting face a0, i.e. a face that is capable of wirelessly charging the wireless power receiving device when in use. Due to the characteristics of the magnet itself, in order to stabilize the magnetic properties of the magnet unit 2, the polarities of the side of the magnet unit 2 close to the emitting surface a0 and the side far from the emitting surface a0 are reversed. That is, the magnet unit 2 is divided into two layers, one layer is disposed on the side adjacent to the emitting surface a0, the two ends are the first magnetic poles 21, and the middle is the second magnetic pole 22. The surface of the magnet unit 2 away from the emitting surface a0 is another layer, and opposite to the above, one end close to the wireless power transmitting coil 1 and the other end away from the wireless power transmitting coil 1 are the second magnetic poles 22, and the first magnetic pole 21 is between the two second magnetic poles 22.
In the present embodiment, the first magnetic pole 21 is an N pole, and the second magnetic pole 22 is an S pole. Alternatively, the first magnetic pole 21 may be an S pole, and in this case, the second magnetic pole 22 may be an N pole. This design varies with specific production needs.
Further, in the present embodiment, the magnet unit 2 is arranged in a circular shape with a predetermined distance from the wireless power transmitting coil 1. Alternatively, the magnet units 2 may be arranged in a shape other than a circle, such as a sector, that is, the magnet units 2 may be arranged only in a partial area of the arc, so as to form an attraction effect with the wireless power transmitting device, thereby assisting the positioning. The number and shape of the magnet units 2 and the distance between the magnet units and the wireless power transmitting coil 1 are not limited, and the magnet units can be changed along with specific production requirements.
Further, the wireless power transmitting apparatus a may further include a housing 5, and the wireless power transmitting coil 1 and the magnet unit 2 are disposed in the housing 5. Alternatively, the shape and size of the housing 5 may vary to follow the internal structure and specific production requirements of the wireless power transmitting device a.
Fig. 2 is a schematic diagram of a wireless power transmitting device adapted to a wireless power receiving device of an iPhone12 series mobile phone according to an embodiment of the present invention. Fig. 3 is a schematic diagram illustrating the operation of the wireless power transmitting device adapting to the first wireless power receiving device according to the embodiment of the present invention. Fig. 4 is a schematic diagram of the operation of the wireless power transmitting device adapted to the second wireless power receiving device according to the embodiment of the present invention. As shown in fig. 2, 3 and 4, the wireless power transmitting device a can be adapted to different wireless power receiving devices.
The magnet unit 4 of the wireless energy receiving device is a magnetic block with magnetism at two ends and non-magnetized in the middle. Due to the nature of the magnet, the central non-magnetized area 43 is magnetized by the two magnetic poles and thus has a weaker magnetic property. That is, the side of the non-magnetized region 43 close to the first magnetic pole 41 is the second magnetic pole 42 with weaker magnetism and opposite to the first magnetic pole 41, and the side close to the second magnetic pole 42 is the first magnetic pole 41 with weaker magnetism. Also, like the wireless power transmitting apparatus a having the transmitting face a0, the wireless power receiving apparatus has the receiving face B0, i.e., a face capable of receiving wireless power, and the polarity of the face of the magnet unit 4 of the wireless power receiving apparatus which is close to the receiving face B0 is opposite to that of the face thereof which is far from the receiving face B0.
When the wireless power transmitting device A is matched with a wireless power receiving device B of an iPhone12 series mobile phone, the wireless power transmitting coil 1 is opposite to the wireless power receiving coil 3. Because the wireless power receiving coil 3 of the iPhone12 series mobile phone is smaller than the common specification, the arrangement pattern of the magnet unit 4 is also smaller than that of the magnet unit 2 of the wireless power transmitting device A. At this time, the second magnetic pole 22 of the magnet unit 2 is opposite to the first magnetic pole 41 of the magnet unit 4 of the wireless power receiving device at the end far away from the wireless power receiving coil 3, and the two magnetic poles are opposite, so that the two magnetic poles attract each other to generate an auxiliary positioning effect. The first magnetic pole 21 of the magnet unit 2 close to one end of the wireless power transmitting coil 1 is opposite to the second magnetic pole 42 with weak magnetism of the non-magnetized area 43, and a certain magnetic attraction force is also formed between the two.
When the wireless power transmitting device a is matched with the first wireless power receiving device B1, the wireless power transmitting coil 1 is opposite to the wireless power receiving coil 3. Since the arrangement pattern of the magnet units 4 of the first radio energy receiving device B1 is larger than that of the magnet units 2 of the radio energy transmitting device a, the second magnetic poles 22 of the magnet units 2 are opposite to the first magnetic poles 41 of the magnet units 4 of the radio energy receiving device at the end close to the radio energy receiving coil 3, and the two magnetic poles are opposite to each other, so that the two magnetic poles attract each other to generate an auxiliary positioning effect.
When the wireless power transmitting device a and the second wireless power receiving device B2 are matched, the wireless power transmitting coil 1 is opposite to the wireless power receiving coil 3. Since the arrangement pattern of the magnet units 4 of the second wireless power receiving device B2 is substantially equal to the arrangement pattern of the magnet units 2 of the wireless power transmitting device a, the second magnetic poles 22 of the magnet units 2 are opposite to the first magnetic poles 41 of the magnet units 4 of the wireless power receiving device at the end close to the wireless power receiving coil 3, and the first magnetic poles 21 of the magnet units 2 at the end far from the wireless power transmitting coil 1 are opposite to the second magnetic poles 42 of the magnet units 4 of the wireless power receiving device at the end far from the wireless power receiving coil 3. The two groups of magnetic poles have opposite magnetism, so that the two groups of magnetic poles attract each other to generate an auxiliary positioning effect.
Fig. 5 is an operational schematic diagram of the MagSafe device adapting to the radio energy receiving device of the iPhone12 series handset. The MagSafe device C is a special wireless power transmitting device adapted to an iPhone12 series mobile phone, and the MagSafe device C and the iPhone12 series mobile phone have mutually corresponding magnetic attraction designs inside, so that the MagSafe device C can generate an auxiliary alignment effect when being used in a matched manner. However, since the wireless power transmitting coil 1 and the wireless power receiving coil 3 which are built in the wireless power transmitting coil 1 and the wireless power receiving coil 3 are smaller than common specifications, when the wireless power transmitting coil 1 and the wireless power receiving coil 3 are matched with other wireless charging transmitting or receiving devices, the wireless power transmitting coil 1 or the wireless power receiving coil 3 cannot be aligned, and further actual wireless charging power cannot reach design power, so that equipment generates heat, and charging efficiency is low. The utility model discloses this problem has not only been solved effectively to wireless power transmitting device A, can carry out wireless charging for iPhone12 series cell-phone, also can carry out wireless charging for other wireless battery charging outfits, still has the assistance-localization real-time function simultaneously, can save user's time. In addition, because the utility model discloses the magnet unit 2 of wireless power transmitting device A is in the part in the wireless energy path that charges still less, therefore the loss is littleer, and charge efficiency is higher.
It should be understood that the kind and type of the wireless power receiving apparatus is not limited to the above three, and therefore, the present application does not limit the correspondence relationship of the positions between the magnet unit 2 of the wireless power transmitting apparatus a and the magnet unit 4 of the wireless power receiving apparatus. The wireless power transmitting device A can adapt to other wireless power receiving devices by adjusting the preset distance between the magnet unit 2 and the wireless power transmitting coil 1 or the arrangement pattern of the magnet unit 2.
Fig. 6 is a schematic structural diagram of an auxiliary positioning device according to an embodiment of the present invention. As shown in fig. 6, the auxiliary positioning device includes magnet units 2 arranged around the charging area 10 at intervals, one end of the magnet unit 2 close to the charging area 10 and the other end far from the charging area 10 are first magnetic poles 21, and a second magnetic pole 22 is arranged between the two first magnetic poles 21. Wherein the first magnetic pole 21 and the second magnetic pole 22 have opposite polarities. That is, the auxiliary positioning device is composed of the magnet units 2, which are arranged and configured in the same way, and the position of the wireless power transmitting coil 1 of the wireless power transmitting device a is the charging area 10.
The auxiliary positioning device is arranged between the wireless power transmitting device and the wireless power receiving device to provide a magnetic attraction positioning function. Further, the auxiliary positioning device further comprises a housing 5. In this embodiment, the housing 5 is a mobile phone housing, and the magnet unit 2 is disposed on the mobile phone housing. The mobile phone with the mobile phone shell comprises a mobile phone shell, wherein the mobile phone shell is provided with a magnetic attraction structure, the magnetic attraction structure is arranged in the mobile phone shell, and the external wireless power transmitting device D is provided with a magnetic attraction structure.
