The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] Please refer to Figure 1 、 Figure 2 and Figure 3 : A mobile power supply for wireless charging, comprising a housing 1, a circuit board 2, a battery 3, a coil 4, a magnet 5, a control unit 6, a charging chip 7, a charging port 8, a power detection unit 9, and a display screen 10. The circuit board 2 is installed inside the housing 1, the battery 3 is installed inside the housing 1 and electrically connected to the circuit board 2, the magnet 5 is installed inside the housing 1, the coil 4, the control unit 6, the charging chip 7, and the power detection unit 9 are installed on the circuit board 2 and electrically connected to the circuit board 2, the charging port 8 is installed on the housing 1 and electrically connected to the circuit board 2, and the display screen 10 is installed on the outer layer of the housing 1 and electrically connected to the circuit board 2.

[0024] The housing 1 includes a cover plate 111 and a bottom case 112, and the cover plate 111 and the bottom case 112 are detachably connected. This facilitates the replacement of the modules inside the housing 1. The magnet 5 is used to adsorb to an external wireless charging device together, ensuring the stability of charging; the control unit 6 is one of a single-chip microcomputer or an MCU module; the charging port 8 is used to connect to an external charger to charge the battery 3 through the charging circuit on the circuit board 2; the charging chip 7 is used to convert electrical energy into a wireless signal and transmit it to the wireless charging device to achieve the wireless charging function; the power detection unit 9 is used to detect the power of the battery 3 in real time and send it to the control unit 6; the display screen 10 is used to display the percentage of power, for example, there is still 60% power.

[0025] When a power bank is needed for wireless charging, it is magnetically attracted to an external wireless charging device through the magnet 5. The battery 3 sends a current signal to the charging chip 7 through the coil 4. The charging chip 7 converts the current signal into a wireless signal and then sends it to the external wireless charging device for charging. The power detection unit 9 detects the power value of the battery 3 in real time and sends it to the control unit 6. The control unit 6 displays the percentage of the power on the display screen 10 for the user to view. When the power is too low, charging the external wireless device is stopped. The power situation of the power bank can also be grasped in real time. When the power is insufficient, the power bank is charged in time.

[0026] In this way, for a wireless charging power bank, through the cooperative setting of the circuit board 2, the battery 3, the coil 4, the magnet 5, the control unit 6, the charging chip 7, the charging port 8, the power detection unit 9, and the display screen 10, the power detection unit 9 detects the power of the battery 3 in real time through the detection circuit on the circuit board 2 and sends it to the control unit 6. The control unit 6 displays the current power percentage on the display screen 10, enabling the user to know how much power the current power bank has and whether charging is needed, thus improving the convenience of using the power bank.

[0027] In one embodiment, the wireless charging power bank further includes an indicator light 11. The indicator light 11 is installed on the side of the housing 1 and is electrically connected to the circuit board 2; there are multiple indicator lights 11 for respectively displaying different colors.

[0028] In this way, since there are multiple indicator lights 11, for example, 3 indicator lights 11, which are respectively displayed in red, green, and blue. When the power value of the battery 3 is lower than a preset threshold, for example, lower than 20% of the rated power, the control unit 6 controls the red light to light up, reminding the user that the power is low; if the power value of the battery 3 is higher than the preset threshold, for example, higher than 80%, the control unit 6 controls the green light to light up, reminding the user that the power is sufficient, enabling the user to understand the power situation of the power bank even when there is no time to look at the display screen 10.

[0029] In one embodiment, the wireless charging power bank further includes a temperature detection module 12. The temperature detection module 12 is installed inside the housing 1 and is electrically connected to the circuit board 2.

[0030] In this way, the temperature detection module 12 detects the temperature value of the housing 1 in real time and sends it to the control unit 6. The control unit 6 compares it with the preset data stored. When the temperature is higher than the preset threshold, the control unit 6 controls the indicator light 11 to give an alarm, reminding the user that the temperature inside the power bank is too high.

[0031] Such as Figure 4As shown, in one embodiment, the wireless charging power bank further includes a coil mounting base 13, and the coil mounting base 13 is mounted on the circuit board 2 for mounting the coil 4.

[0032] In this way, through the setting of the coil mounting base 13, a good fixing effect can be achieved on the coil 4.

[0033] In one embodiment, the wireless charging power bank further includes a lanyard 14. A notch 1121 is formed in the bottom case. One end of the lanyard 14 is fixedly connected to the battery 3, and the other end passes through the notch 1121 so that at least a part of the lanyard 14 is placed outside the housing 1.

[0034] In this way, a part of the rope body of the lanyard 14 is outside the housing 1. When the battery 3 needs to be replaced, after the cover plate 111 and the bottom case 112 are disassembled, pulling the part of the lanyard 14 outside the housing 1 can pull the battery 3 out of the bottom case 112 to complete the quick replacement of the battery 3.

[0035] In one embodiment, the wireless charging power bank further includes a switch 15, and the switch 15 is accommodated on the side of the housing 1 and is electrically connected to the circuit board 2.

[0036] In this way, when the switch 15 is pressed, a start signal is sent to the control unit 6 through the circuit board 2, and the control unit 6 controls the battery 3, the coil 4, the charging chip 7, the charging port 8, and the power detection unit 9, and the display screen 10 to start.

[0037] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
