[0031] Embodiment 1

[0032] Please refer to Figures 1 to 6 Embodiment 1 of the present invention is: a foldable magnetic power bank, comprising a power bank 21, a magnetic component 1 and a support component 2, wherein the magnetic component 1 is mounted on the front surface of the power bank 21 and is rotatable relative to the power bank 21, and the support component 2 is mounted on the rear surface of the power bank 21, the magnetic component 1 comprises a support body, and a wireless charging coil and a magnetic coil component 9 are provided on the support body, and the wireless charging coil 12 is electrically connected to the power bank 21.

[0033] The support body includes a connected metal sheet 14 and a plastic part 13, the metal sheet 14 is provided with an avoidance hole 141, the plastic part 13 is provided with an installation cavity 131 matching the wireless charging coil 12 at the avoidance hole 141, the wireless charging coil 12 is installed in the installation cavity 131, and the periphery of the installation cavity 131 is provided with an installation groove 132 for installing the magnetic suction ring part 9. Compared with the support body made of pure plastic material, the support body composed of the metal sheet 14 and the plastic part 13 can be made thinner in overall thickness under the premise of the same structural strength of the magnetic suction part 1, so as to improve the portability of the foldable magnetic suction power bank to a greater extent.

[0034] In order to make the structure of the magnetic component 1 thinner and lighter, so as to make the overall cross-section height of the foldable magnetic power bank in the folded state lower for users to carry, preferably, the peripheral wall of the installation cavity 131 extends into the avoidance hole 141, and a part of the wireless charging coil 12 is correspondingly located in the avoidance hole 141. In other words, the existence of the avoidance hole 141 makes room for the wireless charging coil 12 to be installed, thereby making the thickness of the magnetic component 1 thinner.

[0035] In some embodiments, the plastic part 13 has a cover 133 that blocks the installation cavity 131. The wireless charging coil 12 is located on the side of the cover 133 close to the metal sheet 14. The existence of the cover 133 can effectively protect the wireless charging coil 12 and reduce the probability of the wireless charging coil 12 being damaged by the impact of foreign objects. For ease of processing, the cover 133 and the plastic part 13 are preferably an integral structure of integral injection molding. Of course, in a specific product, the plastic part 13 may not have the cover 133. In this case, the annular structure on the plastic part 13 constitutes the installation cavity 131.

[0036] Preferably, the mounting groove 132 communicates with the opposite sides of the plastic part 13, and the magnetic attraction ring 9 connects the metal sheet 14. This allows the magnetic attraction ring 9 to be provided with a greater thickness to improve the magnetic attraction effect of the magnetic attraction part 1, or in other words, under the premise that the thickness of the magnetic attraction ring 9 is certain, the thickness of the plastic part 13 can be set to be thinner, thereby further reducing the overall thickness of the magnetic attraction part 1.

[0037] The magnetic attraction component 1 also includes an upper cover 11 and a lower cover 15 which are connected to each other to form a chamber. The wireless charging coil 12, the magnetic attraction ring component 9, the metal sheet 14 and the plastic component 13 are all installed in the chamber. One end of the metal sheet 14 extends out of the chamber to the outside to connect with the first rotating shaft component 23. A mounting hole 16 is provided on the top surface of the upper cover 11 opposite to the wireless charging coil 12. The magnetic attraction ring component 9 is correspondingly located in the mounting hole 16. A PET thin patch component 8 is installed on the plastic component 13. The PET thin patch component 8 is located in the mounting hole 16. The PET thin patch component 8 closes the mounting groove 132 and covers the corresponding area of ​​the mounting cavity 131.

[0038] To facilitate the positioning and installation of the PET thin patch, the plastic part 13 has a positioning frame 134, the edge of the mounting hole 16 is close to the outer wall of the positioning frame 134, and the edge of the PET thin patch part 8 is close to the inner wall of the positioning frame 134. Preferably, the positioning frame 134 and the PET thin patch part 8 are not protruding from the surface of the upper cover 11. Further preferably, the height of the positioning frame 134, the thickness of the PET thin patch and the thickness of the upper cover 11 near the positioning frame 134 are equal, that is, the front surface of the magnetic suction part 1 can form a flat surface.

[0039] In this embodiment, the upper cover 11 and the lower cover 15 are made of leather material, and the edges of the upper cover 11 and the lower cover 15 are integrated into one body. The leather increases the aesthetics and feel of the exterior of the magnetic suction part 1, and can also better reflect the overall quality of the device. In other embodiments, when the upper cover 11 and the lower cover 15 are made of leather material, the edges of the upper cover 11 and the lower cover 15 can also be glued or connected by sewing lines. Of course, in some embodiments, the upper cover 11 / lower cover 15 can also be made of other materials, and the materials of the upper cover 11 and the lower cover 15 can be the same or different.

[0040] In this embodiment, one end of the metal sheet 14 is installed on the power bank 21 through the first rotating shaft 23. Specifically, the first rotating shaft 23 includes a first blade 231, a first shaft and a second blade 232. The first blade 231 and the second blade 232 are connected through the first shaft rotating member, and the second blade 232 is connected to the power bank 21. In order to simplify the structure for assembly, preferably, the first blade 231 is a partial area of ​​the metal sheet 14. In detail, in order to make the folding magnetic power bank in the folded state smaller, the power bank 21 is provided with a first receiving groove 31, and the first rotating shaft 23 is located in the first receiving groove 31. In this embodiment, a partial area of ​​the second blade 232 extends into the power bank 21, and the first receiving groove 31 is located at the edge of the front surface of the power bank 21. In detail, one end of the metal sheet 14 extends to the outside through the cavity formed by the upper cover 1111 and the lower cover 1515, and the part of the metal sheet 14 extending out of the cavity is the first blade 231. Of course, in other embodiments, the specific structure of the first rotating shaft 23 can also be other structures.

[0041] The wireless charging coil 12 includes a connected body 121 and a lead 122. A wire groove 135 connected to the installation cavity 131 is provided on one side of the plastic part 13 close to the metal sheet 14. The wire groove 135 is used to accommodate the lead 122. One end of the lead 122 away from the body 121 passes through the magnetic attraction component 1 and penetrates into the power bank 21 to be electrically connected to the power bank 21.

[0042] In this embodiment, the support member 2 includes an upper shell 17, a lower shell 19 and a support sheet, the support sheet is installed between the upper shell 17 and the lower shell 19, the edges of the upper shell 17 and the lower shell 19 are integrated, the support sheet includes an upper support plate 22 and a lower support plate 18, the upper support plate 22 and the lower support plate 18 are fixedly connected by a second rotating shaft 24, and the upper shell 17 is fixedly bonded to the rear surface of the power bank 21 at the position opposite to the upper support plate 22. Optionally, the upper shell 17 and the lower shell 19 are also made of leather material, and the support sheet is made of metal material. The support strength is increased by the support sheet made of metal material, and the support can be better supported in a triangular structure, while the external aesthetics is increased by the leather material.

[0043] Among them, the first rotating shaft 23 and the second rotating shaft 24 are both damping hinge mechanisms, so that they can be automatically positioned after rotation, thereby better supporting. Moreover, after the magnetic suction member 1 is made thinner as a whole, it is not only convenient for users to rotate the magnetic suction member 1, but also can reduce the damping requirements of the first rotating shaft 23, so that the first rotating shaft 23 can adopt some small damping hinge mechanisms, which is conducive to reducing the volume of the first rotating shaft 23 to ensure the aesthetics of the foldable magnetic suction power bank, and at the same time can reduce the manufacturing cost of the foldable magnetic suction power bank.

[0044] In this embodiment, the power bank 21 includes an upper box 3, a lower box 4, a polymer battery 5 and a mainboard 6. The upper box 3 is fixedly connected to the lower box 4. Optionally, the upper box 3 and the lower box 4 are assembled and fixed together by screws. The mainboard 6 and the polymer battery 5 are installed inside the upper box 3 and the lower box 4. The lead 122 is electrically connected to the mainboard 6, for example by welding.

[0045] In this embodiment, a button port is provided at one end of the upper box 3, in which a button component 7 connected to the main board 6 is installed. The button component 7, the main board 6 and the polymer battery 5 are electrically connected, so that the charging of the power bank 21 can be effectively controlled by the button component 7.

[0046] When using, Figure 5 and Figure 6 As shown, the magnetic member 1 can be opened separately, so that the mobile phone can be directly adsorbed on the magnetic member 1, and the lower support plate 18 can be opened at the same time as the magnetic member 1 is opened, so that a triangular structure is formed between the lower support plate 18 and the power bank 21, thereby increasing the stability of the support, and the support member 2, the power bank 21 and the magnetic core member can be combined to form a mobile phone holder, so that the mobile phone can be directly fixed on the upper part for use, which greatly increases the adaptability;

[0047] After the mobile phone is adsorbed on the magnetic attraction member 1, the internal polymer battery 5 can be connected to the wireless charging coil 12 through the button member 7, and the power in the polymer battery 5 can be directly wirelessly transmitted to the mobile phone battery through the wireless charging coil 12.

[0048] When not in use, the magnetic member 1 and the support member 2 can be folded inward so that the two are placed close to the power bank 21, thereby greatly reducing the volume and facilitating carrying.

[0049] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention.
