Technical Field

[0001] This utility model relates to the technical field of wireless charging equipment for mobile phones, specifically a magnetic wireless power bank. Background Technology

[0002] Smartphones and tablets have become indispensable devices in people's lives; however, their battery life is insufficient to support prolonged use. Power banks are small, convenient, and portable, providing power to these electronic devices and solving the problem of insufficient battery life when using them outdoors or for extended periods.

[0003] Traditional power banks can only charge electronic devices using a charging cable. This may reduce the mechanical damage to the electronic devices due to insufficient support, or the power bank may not be usable if the charging cable is forgotten.

[0004] For users who frequently need to carry power banks, choosing a compact, lightweight charger with wireless charging capabilities is crucial. Traditional wireless chargers haven't solved the issues of portability and speed.

[0005] To address the aforementioned issues, a magnetic wireless charging bank is proposed. Utility Model Content

A control button is provided on one side of the outer shell of the control module. A display module is provided on the control module on the same side. The thickness of the shell of the wireless charging module is greater than the thickness of the control module. The control module is provided with a first fixing block and a second fixing block, which are respectively connected to a first transformer and a second transformer through a connecting groove. The wireless charging module is provided with a first magnetic module attached to the rear side of the shell. The wireless charging coil is provided with a second magnetic module near the front side of the shell. The number of magnets contained in the first magnetic module (110) is greater than the number of magnets contained in the second magnetic module (115).

[0007] Preferably, the wireless charging module has a battery inside, and the wireless charging coil is located at the center of the wireless charging module on one side of the battery, and a second magnetic module is located on the other side of the wireless charging coil.

[0013] Preferably, the first magnetic module and the second magnetic module can enable at least two of the magnetic wireless charging banks to attract each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model, through the setting of a wireless charging module, a first magnetic module, and a second magnetic module, enhances the power bank's adsorption capacity, enabling it to adsorb similar power banks.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figure 1-3 A magnetic wireless charging power bank includes a wireless charging device body, which comprises a control module 10 and a wireless charging module 11. Both the control module 10 and the wireless charging module 11 have outer shells. The control module 11 has a control button 100 located on one side of the outer shell, used to control the charging and discharging of the power bank. On the same side of the control module 10, a display module 101 is located to the right of the control button 100, displaying the current power level and any malfunctions. The shell thickness of the wireless charging module 11 is greater than that of the control module 10 to prevent damage to the control button 100 or the display module 101 due to compression when the power bank is in an magnetic state. Inside the control module 10, a first fixing block 122 and a second fixing block 123 are respectively connected to a first transformer 126 and a second transformer 127 via a connecting groove 125, within which a circuit is laid.

[0025] The wireless charging module 11 has a wireless charging module 110 located on the rear side of the housing. The first magnetic module 110 enhances the magnetic attraction of the magnetic wireless power bank. At least two magnetic wireless power banks can attract each other, and the magnetic wireless power bank can only attract power banks equipped with the wireless charging module 110, or attract devices weighing less than 300 grams. If the device being attracted has a magnetic module, the magnetic attraction of the magnetic power bank is improved.

[0026] The first magnetic module 110 has a heat dissipation module 112 at its lower end. The heat dissipation module 112 is made of metal with good thermal conductivity. The heat dissipation metal sheet is attached to the coil and is also designed with a heat dissipation hole structure to communicate with the external environment to enhance the heat dissipation effect. The heat dissipation metal includes at least aluminum alloy.

[0027] Please see Figure 1-5 The wireless charging module 11 also contains a battery located at its center. A wireless charging coil is also located within the main body of the wireless charging device, surrounding the battery. A second magnetic module 115 of the same size is positioned near the front of the housing of the wireless charging coil. The second magnetic module 115 and the coil are designed in a layered manner in the vertical direction. This design effectively avoids interference, ensuring the efficiency and stability of wireless charging, and enhances the magnetic attraction effect, allowing the magnet to be closer to the device being charged for better magnetic attraction. It also ensures better alignment and coupling between the coil and the receiving device's coil. Both the control module 10 and the wireless charging module 11 have mounting posts 121 that fit into their corresponding housings. Protective silicon sheets 120 for support and protection are located around the mounting posts 121. Fixing posts 124 are located inside the first fixing block 122 and the second fixing block 123.

[0028] Both the first magnetic module 110 and the second magnetic module 115 include at least one magnet. In one power bank, the north pole of the magnet in the first magnetic module 110 faces outward, while in the other magnetic module 115, the south pole of the magnet faces outward, to achieve adsorption. The first magnetic module 110 contains more magnets than the second magnetic module 115. The magnetic force used to attract the device is less than the magnetic force used to attract the power bank. Furthermore, the magnets within the magnetic modules are evenly distributed to ensure uniform force when stacked.

[0029] Furthermore, the first magnetic module 110 and the second magnetic module 115 are provided with fixing buckles around their perimeter, and the first magnetic module 110 and the second magnetic module 115 will attract each other. Inside the power bank, between the second magnetic module 115 and the first magnetic module 110, a plastic sheet of appropriate size is placed to reduce the magnetism inside the power bank.

[0030] Furthermore, the control module 10 is provided with a USB charging and discharging interface 114 located at the bottom of the housing of the control module 10. At the same time, a Type C charging and discharging interface 113 is provided adjacent to the USB charging and discharging interface 114 on the same side. The USB charging and discharging interface 114 and the Type C charging and discharging interface 113 can not only discharge other devices, but also charge the magnetic wireless power bank. In order to avoid damaging the magnetic wireless power bank, the USB charging and discharging interface and the Type C charging and discharging interface cannot charge it at the same time.

[0031] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
