[0042] The utility model provides a magnetic wireless charger, which is used for charging electronic devices with wireless charging function, such as mobile phones, wireless earphone boxes, smart watches, etc.

[0043] In the embodiment of the present utility model, Figures 1 to 7 As shown, the magnetic wireless charger includes a charging base 10, a hinge 30 and a bracket 20. A charging position 11 is provided on the front of the charging base 10. The charging base 10 is provided with a charging circuit, a wireless charging coil 15 and a magnetic structure 16. The wireless charging coil 15 is connected to the charging circuit. The wireless charging coil 15 and the magnetic structure 16 are both arranged corresponding to the charging position 11.

[0044] The hinge 30 includes two connecting plates 31 that are hinged to each other. The rotation axis of the hinge 30 is parallel to the two connecting plates 31. The hinge 30 has a closed state in which the two connecting plates 31 are close together, and one of the connecting plates 31 is fixed to the back of the charging base 10; the bracket 20 is fixed to the other connecting plate 31 of the hinge 30. When the hinge 30 is in the closed state, the bracket 20 is overlapped on the back of the charging base 10.

[0045] Specifically, when it is necessary to charge the electronic device, the electronic device is placed in the corresponding charging position 11, so that the electronic device is magnetically fixed to the magnetic structure 16, and the wireless charging coil 15 cooperates with the receiving coil on the electronic device to realize charging. When the mobile phone is placed in the charging position 11, the mobile phone can be placed in landscape or portrait mode. When the hinge 30 is in a closed state, the two connecting plates 31 are close to each other and are roughly parallel. While ensuring the structural strength of the connecting plate 31, the connecting plate 31 is as thin as possible to reduce the thickness of the hinge 30. For example, the material of the connecting plate 31 is metal.

[0046] The technical solution of the utility model connects the charging seat 10 and the bracket 20 by using a hinge 30, specifically, one of the connecting plates 31 of the hinge 30 is fixed to the back of the charging seat 10, and the other connecting plate 31 is fixed to the bracket 20. Compared with the method of setting the mounting hole of the rotating shaft 312 on the bracket 20, the connecting plate 31 can be directly fixed to the surface of the bracket 20, and the thickness requirement of the bracket 20 is small. The thickness of the bracket 20 can be reduced as much as possible while ensuring the structural strength of the bracket 20, so that the bracket 20 can be made into a thin structure, and then the thickness of the magnetic wireless charger can be reduced, making the magnetic wireless charger lighter and thinner as a whole, increasing convenience, and easy to carry.

[0047] Optionally, the connecting plate 31 is located on the inner side of the bracket 20 ; when the bracket 20 is stored, the hinge 30 can be hidden between the bracket 20 and the charging base 10 .

[0048] In some embodiments, the back of the charging stand 10 is provided with a first mounting groove 12, and the connecting plate 31 fixed to the charging stand 10 is located in the first mounting groove 12; the bracket 20 is provided with a second mounting groove 21, and the connecting plate 31 fixed to the bracket 20 is located in the second mounting groove 21. With such a configuration, when the hinge 30 is in a closed state, the bracket 20 can be closer to the back of the charging stand 10, reducing the gap between the bracket 20 and the charging stand 10 in the closed state, thereby reducing the storage size of the magnetic wireless charger, making it easier to store and carry. Optionally, the second mounting groove 21 is located on the inner side of the bracket 20 (i.e., the side of the bracket 20 facing the charging stand 10), so that the hinge 30 can be hidden between the bracket 20 and the charging stand 10 when the bracket 20 is stored.

[0049] In some embodiments, the bracket 20 is annular, that is, the bracket 20 is a closed ring, which can not only make the bracket 20 have high structural strength, but also make the bracket 20 simple in structure and easy to manufacture. Of course, in other embodiments, the bracket 20 can also be set in an arc or plate shape.

[0050] In some embodiments, a ring groove 13 is provided on the back of the charging stand 10, and when the hinge 30 is in the closed state, the bracket 20 is located in the ring groove 13. That is, by using the space on the charging stand 10 to store the bracket 20, the storage size of the magnetic wireless charger can be further reduced, making it more convenient to store and carry.

[0051] In some embodiments, the annular groove 13 is located at the peripheral portion of the charging base 10 , so that the annular groove 13 can be prevented from occupying the arrangement space of the magnetic attraction structure 16 and the wireless charging coil 15 in the charging base 10 , thereby improving the compactness of the structure of the charging base 10 .

[0052] In some embodiments, the charging base 10 is circular and the bracket 20 is annular, which is convenient for storage. Of course, in other embodiments, the charging base 10 and the bracket 20 are both polygonal.

[0053] In some embodiments, the charging circuit has a charging interface 14, which is located on the side of the charging stand 10, and the charging interface 14 is used to connect to a power source. Specifically, the charging interface 14 can be powered by connecting to a power adapter, or by connecting to the charging interface 14 by connecting to a mobile power supply. By arranging the charging interface 14 on the side of the charging stand 10, it is convenient to connect the charging interface 14 regardless of whether the bracket 20 is in an unfolded state or a folded state.

[0054] In some embodiments, a damping structure is provided between the two connecting plates 31 so that the two connecting plates 31 can be fixed at any angle within the maximum rotation angle range for user convenience. For example, when the user is wirelessly charging the mobile phone, the user can adjust the viewing angle of the mobile phone according to needs.

[0055] Optionally, the maximum rotation angle between the two connecting plates 31 is not less than 180°, that is, one of the connecting plates 31 can be rotated 180° from the closed state, so that the two connecting plates 31 are fully unfolded, which can be applied to a variety of usage scenarios. In the embodiment where the bracket 20 is ring-shaped, the bracket 20 can be used as a hanging ring.

[0056] In some embodiments, one of the connecting plates 31 is provided with two lugs 311, and the side of the other connecting plate 31 is provided with a rotating shaft 312, which is installed between the two lugs 311, and the rotating shaft 312 can rotate relative to at least one of the connecting plates 31. In this way, the thickness of the connecting plate 31 can be reduced, thereby reducing the storage size of the magnetic wireless charger, making it easier to store and carry. The lug 311 can be provided on the connecting plate 31 fixed to the charging stand 10, and the lug 311 can also be provided on the connecting plate 31 fixed to the bracket 20.

[0057] In some embodiments, one of the connecting plates 31 includes a plate body 313 and a connecting portion 314 connected to the side of the plate body 313, the connecting portion 314 is provided with a rotating shaft 312, the connecting portion 314 is located between two lugs 311, and the plate body 313 is spaced from the lugs 311. This can avoid interference between the connecting plate 31 and the lugs 311 when the connecting plate 31 rotates, and can achieve a maximum rotation angle of not less than 180° between the two connecting plates 31 while making the hinge 30 smaller.

[0058] In some embodiments, the magnetic attraction structure 16 includes a plurality of magnets, which are distributed in a ring shape and are located outside the wireless charging coil 15. Specifically, the magnets may be aluminum iron shed magnets or other types of magnets.

[0059] In some embodiments, a magnet is disposed in the bracket 20. This allows the bracket 20 to be adsorbed on a workbench made of magnetic material, making it easy to fix the magnetic wireless charger.

[0060] In some embodiments, reference Figure 8 , Fig.10 or Fig.12The charging stand 10 includes a seat body 17 and a rotating member 18. A charging position 11 is provided on the front of the seat body 17. The rotating member 18 is rotatably mounted on the side of the seat body 17 away from the charging position 11. The rotation axis of the rotating member 18 is perpendicular to the front of the seat body 17. One of the connecting plates 31 is fixed on the side of the rotating member 18 away from the charging position 11. Specifically, the rotation axis of the rotating member 18 is roughly located at the center of the seat body 17 and the rotating member 18, so that the rotating member 18 can rotate on the seat body 17, so that the position of the bracket 20 can be easily changed, so that the user can use it according to actual needs. For example, when the charging interface 14 is arranged on the side of the seat body 17, the charging interface 14 can be rotated to the side by relatively rotating the seat body 17 and the rotating member 18, so as to facilitate plugging and unplugging the power cord. In some embodiments, a first mounting groove 12 is provided on the side of the rotating member 18 away from the charging position 11.

[0061] In some embodiments, reference Fig. 9 , Fig.11 or Fig.13 , an annular groove 171 is provided on the side of the seat 17 away from the charging position 11. The annular groove 171 is in the shape of a ring extending along the circumference of the seat 17. The rotating member 18 is in the shape of a ring and is rotatably installed in the annular groove 171. Specifically, the rotation axis of the rotating member 18 is roughly colinear with the axis of the rotating member 18. By setting the rotating member 18 in the annular groove 171, effective protection can be provided for the rotating member 18, and the rotation stability of the rotating member 18 can be improved. Of course, in other embodiments, the rotating member 18 is in the shape of a plate and is rotatably installed on the back of the seat 17 through the rotating shaft 312.

[0062] Optionally, refer to Fig.11 or Fig.13 The annular groove 171 is spaced from the outer circumference of the seat body 17, so as to prevent the outer circumference of the rotating member 18 from being exposed to the outside, which can effectively protect the rotating member 18 and improve the rotation stability of the rotating member 18. Fig. 9 The annular groove 171 passes through the outer circumferential surface of the seat body 17 .

[0063] There are many ways to rotate the rotating member 18. For example, in one embodiment, referring to Fig. 9 or Fig.13 A first slot 172 is provided on the inner side wall of the annular groove 171 (i.e., the side wall close to the axis of the rotating member 18), and a second slot 181 is provided on the inner circumference of the rotating member 18. The charging stand 10 also includes a retaining spring 19, which is sleeved in the first slot 172 and extends into the second slot 181 to limit the rotating member 18 from escaping from the annular groove 171.

[0064] In another embodiment, referring to Fig.11The annular groove 171 is spaced from the outer circumferential surface of the seat body 17, and the outer side wall of the annular groove 171 (i.e., the side wall away from the axis of the rotating member 18) is provided with a first clamping groove 172, and the outer circumferential surface of the rotating member 18 is provided with a second clamping groove 181. The charging seat 10 also includes a retaining spring 19, which is sleeved in the second clamping groove 181 and extends into the first clamping groove 172 to limit the rotating member 18 from escaping from the annular groove 171.

[0065] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
