[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] This utility model embodiment provides a portable power supply, such as... Figures 1 to 10 As shown, the power bank includes a main body 1 and a wireless charging plate 2. The top of the main body 1 has a top mounting cavity 11, in which a first wireless charging module 12 is installed. The first wireless charging module 12 is covered with a top cover 13. The wireless charging plate 2 is provided with a second wireless charging module 21. A connection opening 131 is opened on one side of the top cover 13, and a rotating shaft 14 is installed in the connection opening 131. A rotating connecting piece 22 is installed on one side of the wireless charging plate 2, and the rotating connecting piece 22 is connected to the rotating shaft 14 with damping rotation. A clearance groove 23 is provided on the first side 25 on the side where the rotating connecting piece 22 is located, and the clearance groove 23 extends along the first side 25.

[0035] By rotating the wireless charging pad 2, the wireless charging pad 2 can be closed onto the upper cover 13, or rotated off the upper cover 13 to stand up.

[0036] The power bank of this invention has a top mounting cavity 11, in which the first wireless charging module 12 is installed and covered by a top cover 13. A connecting opening 131 is provided in the top cover 13, and a rotating shaft 14 is installed in the opening 131. A rotating connecting piece 22 is installed on one side of the wireless charging plate 2. The wireless charging plate 2 is mounted on the top of the main body 1 through a damped rotating connection with the rotating shaft 14. Simultaneously, a clearance groove 23 is provided on the first side 25 to avoid the top edge of the main body 1 during the rotation of the wireless charging plate 2, ensuring normal rotation. In other words, the power bank of this invention ensures normal rotation and use of the wireless charging plate 2, and allows it to be stored under the top cover 13, while directly installing the wireless charging plate 2 through the rotating shaft 14 and connecting piece, eliminating the need for a telescopic rod or L-shaped connecting arm 221, resulting in a simple structure.

[0037] Specifically, when using the hinge 14 and connecting piece to connect the wireless charging pad 2 to the top of the main body 1, the wireless charging pad 2 and the top of the main body 1 will be relatively close. However, by setting the clearance groove 23, the normal rotation of the wireless charging pad 2 can be ensured on this basis. At the same time, by directly using the hinge 14 and connecting piece, the height of the wireless charging pad 2 when it is rotated and standing is relatively low, which can reduce the overall height and center of gravity of the power bank, making it less likely for the mobile phone to tip over when placed on the wireless charging pad 2.

[0038] The top mounting cavity 11 located on the top of the main body 1 can provide a reliable installation space for the first wireless charging module 12, allowing the first wireless charging module 12 to be close to the top cover 13, ensuring normal wireless charging.

[0039] The first wireless charging module 12 and the second wireless charging module 21 can be magnetic wireless charging modules. The rotating connecting piece 22 can be tightly fitted onto the rotating shaft 14 to achieve a damped rotational connection; the rotating shaft 14 can be a damped rotating shaft 14. A circuit board 17 is also provided inside the main body 1, and the circuit board 17 is installed in the top mounting cavity 11. The circuit board 17 serves as a power bank circuit distribution and control component, and it can be implemented in a manner known to those skilled in the art. The first wireless charging module 12 and the second wireless charging module 21 are respectively connected to the circuit board 17. A rechargeable battery (not shown) is also provided inside the main body 1, and the rechargeable battery is electrically connected to the circuit board 17 to store electrical energy for the power bank and provide charging energy. The rechargeable battery can be a lithium-ion battery.

[0040] The top cover 13 can hold a Bluetooth earphone storage case, and the first wireless charging module 12 charges the Bluetooth earphone storage case. The wireless charging pad 2 can charge a mobile phone. In other words, the power bank of this invention provides a wireless charging position at the top cover 13 and a wireless charging position at the wireless charging pad 2.

[0041] Specifically, the rotating connecting piece 22 is installed on the inner side of the clearance groove 23. In this design, installing the rotating connecting piece 22 on the inner side of the clearance groove 23 makes it easier to connect with the rotating shaft 14, and also facilitates the wireless charging plate 2 to be covered on the upper cover 13. Furthermore, a decorative piece 24 is attached to the side of the wireless charging plate 2 facing the upper cover 13. The decorative piece 24 can cover the rotating connecting piece 22, improving the aesthetics.

[0042] The first sidewall 231 of the clearance groove 23 near the rotating connecting piece 22 is set as an inclined surface. The first sidewall 231 is inclined towards the rotating connecting piece 22 from the bottom of the clearance groove 23 to the rotating connecting piece 22. Setting the first sidewall 231 as an inclined surface can better avoid the edge of the corresponding clearance groove 23 on the top of the main body 1.

[0043] A wire passage 2311 is provided on the first sidewall 231 near the rotating connecting piece 22 of the clearance groove 23. The wire 211 of the second wireless charging module 21 is led out from the wire passage 2311 and passes through the connection opening 131 into the main body 1 to be electrically connected to the circuit board 17. The wire passage 2311 and the connection opening 131 facilitate the passage of the wire 211. The wire passage 2311 is located on the first sidewall 231, which also facilitates the guiding and leading out of the wire.

[0044] Furthermore, the rotating connecting piece 22 has two opposing connecting arms 221, which are damped and rotatably connected to the rotating shaft 14. The diameter of the portion of the rotating shaft 14 between the two connecting arms 221 is smaller than the diameter of the rest of the rotating shaft 14. A wire through-hole is formed between the two connecting arms 221. After the wire 211 is led out from the wire through-hole 2311, it passes through the portion of the rotating shaft 14 between the two connecting arms 221 and enters the main body 1. The reduced diameter of the portion of the rotating shaft 14 between the two connecting arms 221 provides more wiring space for the wire 211 to pass through, avoiding interference between the rotating shaft 14 and the guide, and preventing wear on the wire 211.

[0045] Inside the top mounting cavity 11, two oppositely arranged mounting bosses 111 are provided on one side where the rotating shaft 14 is located. The two ends of the rotating shaft 14 are respectively mounted on the top of the two mounting bosses 111. The mounting bosses 111 provide mounting positions for the rotating shaft 14, facilitating stable and convenient installation of the rotating shaft 14.

[0046] Specifically, each of the two mounting bosses 111 has a positioning pin 1112 on its top, and the rotating shaft 14 has positioning holes 141 at both ends, into which the positioning pin 1112 is inserted. The engagement of the positioning pin 1112 with the positioning holes 141 enables the rotating shaft 14 to be positioned during installation, improving the ease and stability of installation. Furthermore, both ends of the rotating shaft 14 are fixed to the two mounting bosses 111 by screws 15. The screws 15 can extend from the other side of the mounting bosses 111 to the top of the mounting bosses 111 and be screwed onto the rotating shaft 14.

[0047] Furthermore, a clearance groove 1111 is provided on the top of the mounting boss 111 near the other mounting boss 111, and the two connecting arms 221 are partially accommodated in the corresponding clearance groove 1111. The clearance groove 1111 ensures the smooth rotation of the connecting arms 221 and avoids interference between the connecting arms 221 and the mounting boss 111.

[0048] A magnet is installed inside the wireless charging pad 2, and a Hall sensor 16 is installed in the top mounting cavity 11 corresponding to the magnet. The Hall sensor 16 is electrically connected to the circuit board 17. When the wireless charging pad 2 is closed on the top cover 13, the magnet and the Hall sensor 16 are aligned. When the wireless charging pad 2 is rotated off the top cover 13 and stood up, the magnet moves away from the Hall sensor 16, the Hall sensor 16 generates a charging start signal, and the circuit board 17 controls the wireless charging pad 2 to start.

[0049] When the wireless charging pad 2 is closed on the top cover 13, the magnet approaches the Hall sensor 16, the Hall sensor 16 generates a charging stop signal, and the circuit board 17 controls the wireless charging pad 2 to turn off.

[0050] By setting corresponding magnets and Hall sensors 16, the wireless charging pad 2 can be automatically powered off when stored on top of the main body 1, and automatically powered on when rotated up from the top of the main body 1, making it convenient to use.
