Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Reference Figures 1 to 11 This utility model provides a wireless charging power bank 90, including a housing 1, a heat dissipation housing 30, a battery 40 and a coil 50. The battery 40 is mounted on the housing 1. The coil 50 is electrically connected to the battery 40 to wirelessly charge external devices. The heat dissipation housing 30 is mounted on the housing 1 and connected to the coil 50 to conduct the heat generated by the coil 50 and the battery 40 to the outside.

[0042] The wireless charging power bank 90 disclosed in this utility model is equipped with a metal heat dissipation shell 30, which can promptly dissipate the heat generated by the coil 50 and battery 40 in the wireless charging power bank 90 when the user uses it. This prevents the wireless charging power bank 90 from reducing power, burning the user, or spontaneously combusting due to overheating. The heat dissipation shell 30 provides the wireless charging power bank 90 with good heat dissipation performance, provides users with a better user experience, and improves the safety of the wireless charging power bank 90.

[0043] It is understood that the battery 40 is installed on the housing 1 of the wireless charging power bank 90, and the heat dissipation housing 30 is installed on the housing 1. Part of the heat dissipation housing 30 is connected to the coil 50. When the wireless charging power bank 90 is working, the heat generated by the coil 50 and the battery 40 will be conducted to the heat dissipation housing 30, and the heat dissipation housing 30 will conduct the heat to the external environment. The heat dissipation housing 30 can be made of heat dissipation materials such as aluminum, iron, and silver to increase heat conduction and thus increase the heat dissipation efficiency of the heat dissipation housing 30.

[0044] Furthermore, the heat dissipation housing 30 is mounted on the housing 1 via the first connecting component 2a.

[0045] It is understood that the heat dissipation housing 30 and the housing 1 can be connected through the first connecting component 2a, without the need for traditional fasteners such as bolts and rivets, which facilitates rapid assembly in the production process, simplifies the production assembly process, and improves efficiency.

[0046] Furthermore, the first connecting component 2a includes a first connector 34 disposed on the heat sink housing 30 and a first locking block 15 disposed on the housing 1.

After the first connector 34 is inserted into the first slot 14, the first locking block 15 inside the first slot 14 engages with the first connecting hole 35 on the first connector 34, so that the heat sink 30 is locked onto the housing 1. The first locking block 15 is removed from the first connecting hole 35, and the first connector 34 is pulled out from the first slot 14, so that the heat sink 30 is detached from the housing 1.

[0048] The metal heat sink 30 and the first connector 34 are integrally formed by a mold. Traditional processes require bending the metal, which reduces its yield strength and causes cracks at the bend, making it prone to bending or breakage. In this embodiment, however, the integral forming using a mold ensures uniform metal strength at the first connector 34, making it more durable.

[0049] Furthermore, an annular boss 33 is provided on the inner side of the heat sink housing 30 at a position corresponding to the second mounting groove 32; a first mounting groove 11 matching the size of the annular boss 33 is provided on the outer side of the housing 1. When the heat sink housing 30 is installed on the housing 1, the annular boss 33 engages in the first mounting groove 11.

[0050] It is understandable that the shape and size of the annular boss 33 match the size of the first mounting groove 11. When the heat sink 30 is installed on the housing 1, the annular boss 33 can be engaged in the first mounting groove 11 to enhance the stability of the heat sink 30 when it is fixed to the housing 1.

[0051] Furthermore, the outer side of the heat sink housing 30 is provided with a first protrusion 31 for supporting the coil 50. A first shaft hole 31a is provided in the center of the first protrusion 31, and a second shaft hole 51 is provided in the center of the coil 50. The coil 50 is disposed on the first protrusion 31, and the first shaft hole 31a and the second shaft hole 51 are positioned correspondingly. A hollow second convex shaft 11a is provided at the center of the first mounting groove 11. The first shaft hole 31a of the heat sink housing 30 and the second shaft hole 51 of the coil 50 are fitted onto the second convex shaft 11a.

[0052] It is understandable that the coil 50 is set on the first boss 31 to connect the coil 50 to the heat sink 30, so that the heat generated by the coil 50 when it is working can be conducted to the heat sink 30. The coil 50 is provided with a second shaft hole 51 in the center and the first boss 31 is provided with a first shaft hole 31a in the center, so that the coil 50 and the heat sink 30 can be fixed on the shaft, which is convenient for installation and the design is simple and practical. The second shaft hole 51 of the coil 50 is sleeved on the second convex shaft 11a, and the first shaft hole 31a of the heat sink 30 is sleeved on the second convex shaft 11a, so that the coil 50 and the heat sink 30 can be fixed, which is simple and practical.

[0053] Furthermore, the wireless charging power bank 90 also includes a ring-shaped magnet 60, which is used to attract external devices; the magnet 60 is connected to the housing 1 through a second connecting component 3a; a second mounting groove 32 is provided around the first protrusion 31 on the heat dissipation housing 30, and the magnet 60 is disposed in the second mounting groove 32.

[0054] It is understood that the wireless charging power bank 90 is equipped with a magnet 60, which is connected to the housing 1 via a second connecting component 3a. This facilitates rapid assembly during production, simplifies the assembly process, and improves efficiency. The magnet 60 enables the wireless charging power bank 90 to have a magnetic attraction function, allowing it to attract external charging devices and providing users with a richer user experience. Specifically, the magnet 60 used in this embodiment has a strong magnetic force, ensuring that even when the wireless charging power bank 90 is using a battery 40 with a capacity of 10,000 mAh or more, it remains attached to the external charging device and will not fall off when the user removes the device.

[0055] Furthermore, the second connecting component 3a includes a protrusion 61 disposed on the magnet 60 and a slot 12 disposed on the housing 1. The magnet 60 includes an extension end, and the protrusion 61 is disposed on the extension end. A first through hole 11d is provided in the first mounting groove 11, and a second through hole 32b is provided in the second mounting groove 32 at a position corresponding to the first through hole 11d. A slot 12 matching the protrusion 61 is provided on the inner side of the housing 1. After the extension end passes through the second through hole 32b and the first through hole 11d, the protrusion 61 is engaged in the slot 12 so that the magnet 60 is installed in the second mounting groove 32.

[0056] It is understandable that after the extended end of the magnet 60 passes through the first through hole 11d and the second through hole 32b, the protrusion 61 on the extended end can be engaged in the slot 12 inside the housing 1 so that the magnet 60 is fixed in the second mounting slot 32. The design is simple and practical, convenient and quick to assemble, and avoids the use of screws, thus improving assembly efficiency.

[0057] Furthermore, the wireless charging power bank 90 also includes a cover 70 that matches the size of the second mounting slot 32, and the cover 70 is connected to the housing 1 via a third connecting component 4a.

[0058] It is understandable that the cover plate 70 covers the housing 1, which can protect the coil 50 and the magnet 60, and can improve the overall aesthetics; the cover plate 70 is connected to the housing 1 through the third connecting component 4a, which facilitates quick assembly during production, simplifies the production assembly process, and improves efficiency.

[0059] Furthermore, a first convex shaft 71 is provided in the center of the inner side of the cover plate 70, and a protruding second locking block 72 is provided on one side of the first convex shaft 71. The first convex shaft 71 passes through the first shaft hole 31a and the second shaft hole 51 and is inserted into the hollow second convex shaft 11a. The second locking block 72 is engaged with the inner wall of the housing 1 so that the cover plate 70 covers the coil 50 and is installed in the second mounting groove 32.

[0060] It is understood that the first convex shaft 71 in the center of the cover plate 70 can be inserted into the hollow second convex shaft 11a, and the second locking block 72 provided on the first convex shaft 71 can be engaged with the inner side wall of the housing 1 so that the cover plate 70 is connected to the housing 1; the first convex shaft 71 is elastic, which makes it convenient for users to install and remove the cover plate 70.

[0062] It is understood that the position of the second connector 73 corresponds one-to-one with the position of the second connecting hole 32a. After the second connector 73 is inserted into the second connecting hole 32a, the third locking block 74 on the second connector 73 can engage with the inner side wall of the housing 1, further fixing the cover plate 70. The second connector 73 is elastic, which facilitates the quick disassembly and quick installation of the cover plate 70.

[0063] Furthermore, the wireless charging power bank 90 also includes a control circuit board 80, which is disposed inside the housing 1 and electrically connected to the battery 40.

[0064] It is understandable that the control circuit board 80 can control the power on and off of the wireless charging power bank 90, and can also convert the current into alternating current and conduct it to the coil 50, so that the coil 50 generates a magnetic field.

[0065] Furthermore, a first wire hole 11c is provided in the first mounting groove 11, and a second wire hole 32c is provided in the second mounting groove 32 at a position corresponding to the first wire hole 11c.

[0066] It is understandable that 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, making reasonable use of space and with a simple and practical design.

[0067] Furthermore, an indicator light 81 is provided on the control circuit board 80; a slot 24 is provided on the housing 1 at the position corresponding to the indicator light 81.

[0068] It is understandable that there are several indicator lights 81 arranged in sequence. The indicator lights 81 can display the battery level. The more battery power is left, the more indicator lights 81 will light up. The less battery power is left, the fewer indicator lights 81 will light up.

[0069] In some embodiments, indicator light 81 can be a single indicator light, the color of which changes according to the battery level. When the battery is high, the indicator light 81 is more green, and when the battery is low, the indicator light 81 is more red.

[0070] Users can see indicator light 81 through the slot, thus knowing how much battery power is left, improving the user experience.

[0071] Furthermore, a power interface 82 is also provided on the control circuit board 80.

[0072] It is understandable that users can connect an external power cord to the power interface 82 to charge the wireless charging power bank 90. ​​The power interface 82 can be, but is not limited to, commonly used interfaces such as USB and Type-C.

[0073] Furthermore, a power button 21 is provided on the housing 1, and the power button 21 is electrically connected to the control circuit board 80.

[0075] Furthermore, the housing 1 includes a first housing 10 and a second housing 20 that are detachably connected, and the housing 1 also includes a fourth connecting component 1a, through which the first housing 10 and the second housing 20 are connected.

[0076] It can be understood that the housing 1 is formed by connecting the first housing 10 and the second housing 20, and the first housing 10 and the second housing 20 form an accommodating space; the first housing 10 and the second housing 20 are connected by the fourth connecting component 1a, which does not require traditional fasteners such as bolts and rivets, making it convenient and quick to assemble, simplifying the production assembly process and improving efficiency.

[0077] Furthermore, the fourth connecting component 1a includes a third connector 22 disposed inside the second housing 20 and a fourth connecting hole 13a disposed on the first housing 10. One end of the third connector 22 includes a fourth locking block 23. The first housing 10 includes a second slot 13, and the fourth connecting hole 13a is disposed in the second slot 13. The third connector 22 is inserted into the second slot 13, and the fourth locking block 23 is engaged in the fourth connecting hole 13a to connect the first housing 10 with the second housing 20. The fourth locking block 23 is disengaged from the fourth connecting hole 13a to detach the second housing 20 from the first housing 10.

[0078] It is understood that there are 4 third connectors 22 and 4 second slots 13. The positions of the 4 third connectors 22 correspond one-to-one with the positions of the 4 second slots 13. After the third connector 22 is inserted into the second slot 13, the fourth locking block 23 provided on the third connector 22 engages in the fourth connecting hole 13a in the second slot 13, so that the first housing 10 is locked onto the second housing 20.

[0079] Furthermore, several heat dissipation grooves 36 are provided on the surface of the heat dissipation housing 30.

[0080] It is understandable that the heat dissipation groove 36 can increase the heat dissipation area of ​​the heat dissipation shell 30, further improving the heat dissipation performance of the heat dissipation shell 30. At the same time, when the external device is placed on the wireless charging power bank 90 for charging, the heat dissipation groove 36 can reduce the contact area between the heat dissipation shell 30 and the external device, resulting in less heat accumulation and improved heat dissipation performance.

[0081] Furthermore, the wireless charging power bank 90 also includes a heat insulation plate 91, which is disposed on both sides of the battery 40. The heat insulation plate 91 can be made of aerogel.

[0082] It is understandable that there are two heat insulation plates 91. When the wireless charging power bank 90 is working, the battery 40 will generate heat. The heat insulation plates 91 are attached to both sides of the battery 40 and cover the main surface of the battery 40. This can effectively block the heat generated by the battery 40 from being transferred to the outer shell 1, providing users with a better user experience. At the same time, the heat insulation plates 91 can also play a buffering role and protect the battery 40.

[0083] Furthermore, the surface of the cover plate 70 is provided with several strip-shaped protrusions 75.

[0084] It is understandable that the several strip-shaped protrusions 75 on the surface of the cover plate 70 can increase the surface area of ​​the cover plate 70, thereby increasing the heat dissipation area and further enhancing the heat dissipation performance.

[0085] Furthermore, such as Figure 12 As shown, in another embodiment, the internal structure is the same, so it is not shown in disassembly. The difference is that the heat sink 30 is mounted on the housing 1 via a fifth connecting assembly; the fifth connecting assembly includes a positioning groove 37 disposed on the heat sink 30 and an elastic member 16 disposed on the housing 1. One end of the elastic member 16 is raised outward, and the other end of the elastic member 16 is engaged in the positioning groove 37 so that the heat sink 30 is mounted on the housing 1.

[0086] It is understood that there are two elastic elements 16, which are located on both sides of the housing 1. There are also two positioning grooves 37, which are located on both sides of the inner wall of the heat dissipation housing 30. The housing 1 includes the elastic element 16, which is elastic and has one end that is raised outward. The inner wall of the heat dissipation housing 30 is provided with positioning grooves 37. When the heat dissipation housing 30 is fitted onto the housing 1, the housing 1 compresses the elastic element 16 until the raised end of the elastic element 16 slides into the positioning groove 37, thus fixing the heat dissipation housing 30 onto the housing 1. By using the installation method of the fifth connecting component, production steps can be saved, installation speed can be accelerated, production efficiency can be improved, and costs can be saved at the same time.
