Embodiments for Carrying out the Invention

[0018] Hereinafter, with reference to the accompanying drawings in the embodiments of the present invention, the technical proposals in the embodiments of the present invention will be clearly and completely described. Obviously, the embodiments described here are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments that can be obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0019] Refer to FIGS. 1 to 11 in combination. The wireless charging mobile power source 90 according to the present invention includes a first case 10, a second case 20, a heat dissipation case 30, a battery 40 and a coil 50. The first case 10 and the second case 20 are connected to each other to form an accommodation space. The battery 40 is disposed in the aforementioned accommodation space. The heat dissipation case 30 is connected to the first case 10 or the second case 20. A part of the heat dissipation case 30 is disposed on the outermost side of the wireless charging mobile power source 90. The coil 50 is electrically connected to the battery 40 and is used for wireless charging of an external device. Further, the coil 50 is in contact with the heat dissipation case 30, and the heat dissipation case 30 is used for conducting the heat generated by the coil 50 and the battery 40 to the outside. As can be seen, in this embodiment, a part of the heat dissipation case 30 is disposed on the outermost side of the wireless charging mobile power source 90. However, in other embodiments, the heat dissipation case 30 may be disposed at other positions, and other cases or cover plates may be further disposed on the outer heat dissipation case 30. However, it is sufficient that the coil 50 is in contact with the heat dissipation case 30 and the heat dissipation case 30 can conduct the heat generated by the coil 50 and the battery 40 to the outside of the coil 50.

[0020] Since the wireless charging mobile power source 90 disclosed in the present invention is provided with a metal heat dissipation case, when the user uses the wireless charging mobile power source 90, the heat generated by the coil and the battery in the wireless charging mobile power source 90 can be quickly conducted to the outside. Thereby, the wireless charging mobile power source 90 can prevent problems such as a decrease in output power due to too high a temperature, burns to the user, and spontaneous ignition. The heat dissipation case 30 imparts excellent heat dissipation performance to the wireless charging mobile power source 90, brings a better use experience to the user, and can improve the safety of the wireless charging mobile power source 90.

[0021] Note that the battery 40 is disposed inside the wireless charging mobile power supply 90 and abuts against the first case 10 and the second case 20. The heat dissipation case 30 is connected to the first case 10 or the second case 20, and a part of it is connected to the coil 50. When the wireless charging mobile power supply 90 operates, the heat generated from the coil 50 and the battery 40 is conducted to the heat dissipation case 30, and the heat dissipation case 30 conducts the heat to the external environment. The heat dissipation case 30 may be made of a heat dissipation material such as aluminum, iron, or silver.

[0022] Furthermore, the first case 10 and the second case 20 are detachably connected to each other.

[0023] As can be seen, since the first case 10 and the second case 20 are detachably connected, conventional fasteners such as bolts and rivets are not required, and quick assembly and disassembly are possible. Thereby, the assembly process can be simplified and the efficiency can be improved.

[0024] Furthermore, the heat dissipation case 30 is detachably covered on the first case 10.

[0025] As can be seen, for the connection method between the heat dissipation case and the first case, conventional fasteners such as bolts and rivets are not required, quick assembly and disassembly can be realized, the assembly process can be simplified, and the efficiency can be improved.

[0026] Furthermore, on the outside of the heat dissipation case 30, a circular first protrusion pedestal 31 for placing the coil 50 is provided. A first shaft hole 31a is provided at the center of the first protrusion pedestal 31. A second shaft hole 51 is provided at the center of the coil 50. The coil 50 is disposed on the first protrusion pedestal 31 so that the positions of the first shaft hole 31a and the second shaft hole 51 are aligned.

[0027] As can be seen, since the coil 50 is disposed on the first protrusion pedestal 31 so as to be in contact with the heat dissipation case 30, the heat generated when the coil 50 case operates is conducted to the heat dissipation case. Also, the second shaft hole 51 provided at the center of the coil 50 and the first shaft hole 31a provided at the center of the first protrusion pedestal 31 facilitate the fixing of the coil 50 and the heat dissipation case 30 to the shaft body, enabling easy attachment, with a simple and practical design.

[0028] Furthermore, the wireless charging mobile power source 90 further includes an annular magnet 60 for adsorbing an external device. The heat dissipation case 30 is provided with a second annular groove 32 so as to surround the first protrusion pedestal 31. The magnet 60 is disposed within the second annular groove 32.

[0030] Furthermore, an annular boss 33 is provided at a position corresponding to the second annular groove 32 inside the heat dissipation case 30. An outer side of the first case 10 is provided with a first annular groove 11 that matches the dimensions of the annular boss 33. After the heat dissipation case 30 is attached to the first case 10, the annular boss 33 is engaged within the first annular groove 11.

[0031] As can be understood, since the shape and dimensions of the annular boss 33 match those of the first annular groove 11, when the heat dissipation case 30 is attached to the first case 10, the annular boss 33 is engaged within the first annular groove 11, thereby improving the stability when the heat dissipation case 30 and the first case 10 are fixed.

[0032] Furthermore, a hollow first protruding shaft 11a is provided at the center position of the first annular groove 11, and the first shaft hole 31a of the heat dissipation case 30 and the second shaft hole 51 of the coil 50 are engaged with the outer periphery of the first protruding shaft 11a.

[0033] As can be understood, the second shaft hole 51 of the coil 50 is fitted onto the first protruding shaft 11a, and the first shaft hole 31a of the heat dissipation case 30 is fitted onto the first protruding shaft 11a, so that the coil 50 and the heat dissipation case 30 are firmly fixed, and the design is simple and practical.

[0034] Furthermore, the wireless charging mobile power supply 90 further includes a cover plate 70 that matches the dimensions of the second annular groove 32.

The second protruding shaft 71 passes through the first shaft hole 31a and the second shaft hole 51 and is inserted into the hollow first protruding shaft 11a. The first engaging hook 72 is engaged with the inner wall of the first case 10. Thereby, the cover plate 70 is adhered to the upper surface of the coil 50 and is mounted in the second annular groove 32.

[0035] As can be seen from the above description, in the present invention, the second protruding shaft 71 at the center of the cover plate 70 is inserted into the hollow first protruding shaft 11a, and the first engaging hook 72 provided on the second protruding shaft 71 is engaged with the inner wall of the first case 10, thereby connecting the cover plate 70 and the first case 10 to each other. Since the second protruding shaft 71 has elasticity, the attachment operation and removal operation of the cover plate 70 by the user are facilitated.

[0036] Furthermore, a plurality of first connection members 73 are provided at the inner edge of the cover plate 70. On one side of the first connection member 73, a second engaging hook 74 is provided. A second connection hole 32a is provided in the second annular groove 32. A first connection hole 11b corresponding to the position of the second connection hole 32a is provided in the first annular groove 11. The first connection member 73 is inserted into the second connection hole 32a and the first connection hole 11b. The second engaging hook 74 is engaged with the inner wall of the first case 10.

[0037] Note that the positions of the plurality of first connection members 73 correspond one-to-one to the positions of the plurality of second connection holes 32a. After the first connection member 73 is inserted into the second connection hole 32a, the second engagement hook 74 on the first connection member 73 is engaged with the inner wall of the first case 10. Thereby, the fixing of the cover plate 70 is further strengthened. And since the first connection member 73 has elasticity, it becomes easy to quickly remove or quickly attach the cover plate 70.

[0038] Furthermore, the magnet 60 is provided with an extended end, and a bump 61 is provided on the extended end. A first through hole 11d is provided in the first annular groove 11, and a second through hole 32b is provided at a position corresponding to the first through hole 11d in the second annular groove 32. Inside the first case 10, a fitting recess 12 that matches the bump 61 is provided. After the extended end penetrates through the second through hole 32b and the first through hole 11d, the bump 61 fits into the fitting recess 12 so that the magnet 60 can be mounted in the second annular groove 32.

[0039] As can be seen from the above description, after the extended end of the magnet 60 penetrates through the first through hole 11d and the second through hole 32b, the bump 61 at the extended end engages with the fitting recess 12 in the first case 10, thereby fixing the magnet 60 in the second annular groove 32. Such a design is simple and practical, and can achieve rapid assembly and disassembly.

[0040] Furthermore, the wireless charging mobile power supply 90 includes a control circuit board 80. The control circuit board 80 is disposed in the accommodation space and is electrically connected to the battery 40.

[0041] The control circuit board 80 can control the energization and power-off of the wireless charging mobile power supply 90, and can further convert direct current into alternating current and conduct it to the coil 50 to generate a magnetic field in the coil 50.

[0043] With the configuration in which one end of the coil 50 is connected to the control circuit board 80 through the first wire hole 11c and the second wire hole 32c, space can be rationally utilized, and a simple and practical design can be obtained.

[0044] Furthermore, an indicator lamp 81 is provided on the control circuit board 80. An opening 24 is provided at a position corresponding to the indicator lamp 81 in the second case 20.

[0045] Also, a plurality of indicator lamps 81 are arranged in sequence. The more battery remaining, the more indicator lamps 81 are lit. Conversely, the less battery remaining, the fewer indicator lamps 81 are lit.

[0046] In some embodiments, there may be one indicator lamp 81, and the color of the indicator lamp 81 changes according to the remaining amount of the battery.

[0047] The user can know the remaining amount of the battery by looking at the indicator lamp 81 through the opening, improving the usage experience.

[0048] Furthermore, a power interface 82 is further provided on the control circuit board 80.

[0049] Also, the user can charge the wireless charging mobile power source 90 by connecting an external power cable to the power interface. The power interface 82 is not limited to common interfaces such as USB and Type-C.

[0050] Furthermore, the second case 20 is provided with a power button 21 that is electrically connected to the control circuit board 80.

[0051] By pressing the power button 21, the user can control the start or stop of charging of the wireless charging mobile power supply 90, and the operation is easy.

[0052] Furthermore, a second connection member 22 is provided inside the second case 20, and a third engaging hook 23 is provided at one end of the second connection member 22.
