[0042] Specifically, the wireless charging module 21 of the first wireless charging pad 2 is a magnetic wireless charging coil. This magnetic wireless charging coil can magnetically hold the watch in place while it is charging, improving charging stability and efficiency. The rechargeable battery module 11 includes a rechargeable battery 111, which can be a lithium-ion battery. The circuit board 12 serves as the distribution and control component of the mobile power supply circuit. It can be a single circuit board 12 or multiple circuit boards 12 used in combination. It can be implemented in ways known to those skilled in the art, and will not be described in detail here.

[0043] Specifically, a first wiring port 22 is provided on the first wireless charging plate 2 at the rotating plate 25; a second wiring port 131 is provided in the receiving groove 13 at the pivot member 14; the wires of the wireless charging module pass through the first wiring port 22 and the second wiring port 131 in sequence and are introduced into the main body 1 to be electrically connected to the circuit board 12. The opening of the first wiring port 22 and the second wiring port 131 facilitates the wires of the wireless charging module 21 to be led out from the first wireless charging plate 2 and introduced into the main body 1. The first wiring port 22 is opened at the rotating plate 25, which facilitates the opening of the first wiring port 22 and its centralized arrangement with the rotating plate 25. Similarly, the second wiring port 131 is also opened at the pivot member 14, and the wires are led out and introduced from the rotating position of the first wireless charging plate 2, reducing the exposure of the wires.

[0044] Further integration Figure 7 As shown, the power bank also includes a cable management sleeve 15, which is installed at the second cable management port 131. The cable management sleeve 15 has a cable passage 151 through which the wire passes into the main body 1. The cable management sleeve 15 can cover the second cable management port 131, preventing the interior of the main body 1 from being exposed and improving the aesthetics.

[0045] Specifically, a mounting boss 132 is provided on the lower edge of the receiving groove 13, and the mounting boss 132 extends in the width direction of the receiving groove 13; the rotating shaft 14 is mounted on the mounting boss 132. The mounting boss 132 provides an installation position for the rotating shaft 14, and the setting of the mounting boss 132 can facilitate the installation of the rotating shaft 14.

[0046] Further integration Figures 9 to 11As shown, the cable routing sleeve 15 includes a snap-fit ​​part 152 and a plug-in part 153, which are connected in an L-shape. The snap-fit ​​part 152 has a retaining support part 154 on both sides. The second cable routing opening 131 is located at the mounting protrusion 132. Retaining support grooves 1321 are formed on both sides of the second cable routing opening 131 on the mounting protrusion 132. The snap-fit ​​part 152 snaps onto the inner side of the upper edge of the second cable routing opening 131, the plug-in part 153 plugs into the inner side of the lower edge of the second cable routing opening, and the retaining support part 154 is supported on the retaining support groove 1321.

[0047] The latching part 152 latches onto the inner side of the upper edge of the second wiring port 131, and the insertion part 153 inserts into the inner side of the lower edge of the second wiring port, preventing the wiring sleeve 15 from coming out towards the opening of the receiving groove 13. The abutting support part 154 supports the abutting support groove 1321, preventing the wiring sleeve 15 from falling into the main body 1. Furthermore, the latching part 152 can abut against the upper edge of the second wiring port 131. Thus, the wiring sleeve 15 can be limited from all directions, ensuring its installation stability. At the same time, it does not require additional fasteners, making the structure simple and convenient. Specifically, the wiring sleeve 15 is a plastic part that can deform to a certain extent. During assembly, the insertion part 153 is first inserted into the inner side of the lower edge of the second wiring port, and the abutting support part 154 is simultaneously supported on the abutting support groove 1321. Then, the latching part 152 is pressed into the inner side of the upper edge of the second wiring port 131 to complete the assembly. The latching part 152 is provided with a hook 1521 having a bevel 15211, which facilitates the latching part 152 being pressed into the inner side of the upper edge of the second wiring port 131. A corresponding groove 17 can be provided on the inner side of the upper edge of the second wiring port 131, and the hook 1521 is engaged in the groove 17.

[0048] The rotating shaft 14 is provided with a rotating shaft portion 141, which is rotatably connected to the rotating plate 25 via a rotating shaft 26. Positioning holes 142 are provided on both sides of the rotating shaft portion 141. A positioning protrusion 132 is provided on the side of the mounting boss 132 facing the inlet of the receiving groove 13, corresponding to the positioning holes 142, and is inserted into the positioning holes 142. The rotating shaft portion 141 is rotatably connected to the rotating plate 25 via the rotating shaft 26. The rotating shaft 26 can be a damping rotating shaft 26, allowing the first wireless charging plate 2 to rotate while having a certain damping, thereby maintaining the rotation angle or ensuring stable storage in the receiving groove 13. The cooperation of the positioning holes 142 and the positioning protrusion 1322 serves to position the rotating shaft 14, facilitating its installation.

[0049] Furthermore, on the rotating shaft 14, mounting holes are provided on both sides of each positioning hole 142. The rotating shaft 14 is screwed onto the mounting boss 132 through the mounting holes by screws 16 passing through the mounting holes. The rotating shaft 14 is further fixed by screws 16 to ensure its secure installation.

[0050] The upper edge of the receiving groove 13 is set as an inclined surface 133, which slopes outward from the bottom of the receiving groove 13 to the opening of the receiving groove 13. In this design, setting the upper edge of the receiving groove 13 as an inclined surface 133 provides a locking space for the first wireless charging pad 2 to rotate out, making it convenient for the user to rotate the first wireless charging pad 2 from the receiving groove 13. Furthermore, a handle groove 24 is provided on the side of the first wireless charging pad 2 opposite to the rotating piece 25. The handle groove 24 facilitates the user to apply force to rotate the first wireless charging pad 2 from the receiving groove 13.

[0051] The first wireless charging pad 2 is provided with a magnet 23, and a Hall sensor (not shown) is provided in the main body 1 at the corresponding receiving slot 13. The Hall sensor is electrically connected to the circuit board 12. When the first wireless charging pad 2 is stored in the receiving slot 13, the magnet 23 corresponds to the Hall sensor.

[0052] When the first wireless charging pad 2 is rotated out of the receiving slot 13, the magnet 23 moves away from the Hall sensor, the Hall sensor generates a charging start signal, and the circuit board 12 controls the first wireless charging pad 2 to start. When the first wireless charging pad 2 is put back into the receiving slot 13, the magnet 23 moves closer to the Hall sensor, the Hall sensor generates a charging stop signal, and the circuit board 12 controls the first wireless charging pad 2 to stop.

[0053] By setting the corresponding magnet 23 and Hall sensor, the first wireless charging pad 2 can be automatically powered off when it is stored in the receiving slot 13, and automatically powered on when it is removed from the receiving slot 13, which is convenient to use.
