[0015] 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.

[0016] Example 1: Please refer to Figure 1 - Figure 7This utility model provides a technical solution: a portable power bank, including a power bank body 1, a charging cable 2 fixedly connected to one side of one end of the power bank body 1, a slot 14 formed at one corner of the power bank body 1, a charging end 20 fixedly connected to one end of the charging cable 2, a T-shaped rod 31 fixedly installed at the middle of the lower end of the charging end 20, and triangular guide rods 33 fixedly installed on both sides of the middle of the upper end of the charging end 20, a T-shaped groove 30 formed at the lower part of the middle of one end of the slot 14, and triangular guide grooves 32 formed on both sides of the upper part of the middle of one end of the slot 14, a sliding groove 22 formed at the lower end of the middle of one side of the slot 14, a sliding plate 23 slidably engaged in the middle of the sliding groove 22, a spring 26 fixedly connected to one end of the sliding groove 22, one end of the spring 26 fixedly connected to one side of the sliding plate 23, a pressure plate 29 fixedly connected to one end of the sliding plate 23, and a pressure plate 29 in the middle of the sliding plate 23. A bottom slot 25 is provided below the slide plate 23, a top slot 24 is provided above the middle of the slide plate 23, a notch 28 is provided on one side of the middle of the slide plate 23, and limit plates 27 are fixedly installed on both sides of the middle of the slide groove 22 near the spring 26. The charging end 20 is inserted into the middle of the slot 14, the triangular guide rod 33 is slidably engaged in the middle of the triangular guide groove 32, and the triangular guide rod 33 and the triangular guide groove 32 are engaged. The T-shaped groove 30, the slot 14 and the triangular guide groove 32 are connected. The T-shaped rod 31 is slidably engaged in the middle of the slide plate 23. The lower end of the T-shaped rod 31 with a larger diameter is slidably engaged in the middle of the bottom slot 25, and the middle part of the T-shaped rod 31 with a smaller diameter is slidably engaged in the middle of the top slot 24. The opening of the notch 28 is larger than the diameter of the T-shaped rod 31. The end of the slide plate 23 abuts against the two limit plates 27. A metal sleeve 21 is provided on the outside of the charging cable 2.

[0017] In this embodiment, the charging cable 20 is mechanically locked to the power bank slot 14, and a metal sleeve 21 is fitted over the outside of the charging cable 2 to reinforce the cable body. This allows the charging cable 2 to be converted into a load-bearing lanyard, supporting the hanging of the power bank, such as on a backpack, wrist, or tent, reducing the risk of loss due to clutter on the desktop or outdoors. When it is necessary to release the restriction of the charging end 20 at the end of the charging cable 2, simply press the pressure plate 29 to drive the sliding plate 23 to squeeze inward along the slide groove 22. During this process, the spring 26 will contract. When the end of the sliding plate 23 abuts against the two limiting plates 27, the notch 28 of the sliding plate 23 will be located on one side of the T-shaped rod 31. Since the size of the notch 28 is larger than the T-shaped rod 31, the sliding plate 23 will release the restriction on the T-shaped rod 31, and the user can pull it outward. The entire charging cable 2 and charging end 20 can be used for charging. After charging is complete, when it is necessary to lock the charging end 20, repeat the above pressing operation to push the slide plate 23 inward until it abuts against the limiting plate 27. At this time, insert the charging end 20 into the slot 14 along the T-slot 30. The T-rod 31 can be directly inserted into the middle of the slide plate 23. Release the pressure plate 29, and the spring 26 will push the slide plate 23 to reset. The notch 28 of the slide plate 23 will be misaligned with the T-rod 31, so that the slide plate 23 limits the T-rod 31, so that the charging cable 2 forms a closed loop structure that can be used for suspension. Throughout the process, the triangular guide rod 33 at the top of the charging end 20 and the guide slot provide precise guidance to ensure that the locking position is automatically aligned when inserted, reducing misoperation.

[0018] Example 2: As Figure 1 - Figure 7 As shown, a charging port 11 is provided in the middle of one end of the power bank body 1, a switch button 12 is provided on the other side of the middle of one end of the power bank body 1, a wireless charging magnetic coil 13 is provided in the middle of the upper end of the power bank body 1, and a bracket 10 is rotatably installed on one side of the middle of the lower end of the power bank body 1.

[0019] In this embodiment, the charging interface 11 can quickly replenish the power bank body 1 to meet subsequent discharge needs. The top wireless charging magnetic coil 13 supports magnetic wireless charging of devices without plugging or unplugging the wires. The magnetic positioning avoids displacement and interruption. The wired interface and wireless module can work simultaneously to power multiple devices at the same time, improving the efficiency of multi-device users. The switch button 12 supports one-click wake-up or power-off of the power bank to avoid accidental touches that cause power loss. Users can also adjust the stand 10 to a suitable position and lean the power bank body 1 against the table, making it more convenient to use with the wireless charging magnetic coil 13.

[0020] like Figure 1 - Figure 7As shown, an external power source charges the internal battery pack of the power bank through the charging port 11. When the battery pack discharges, the power is transmitted to the charging terminal 20 through the charging cable 2 to power devices such as mobile phones. The wireless charging magnetic coil 13 enables the power bank to have wireless charging functionality. Combined with the charging cable 2, it achieves both wireless and wired charging modes, making it more practical. Users can also adjust the stand 10 to a suitable position and lean the power bank 1 against a table, making it more convenient to use with the wireless charging magnetic coil 13.

[0021] When not in use, the T-shaped rod 31 of the charging end 20 can be inserted into the slot 14. The slide plate 23 will reset under the action of the spring 26, causing the notch 28 to move away from the T-shaped rod 31. The bottom slot 25 will hold the large-diameter part of the lower end of the T-shaped rod 31, and the top slot 24 will restrain the small-diameter part of the middle of the T-shaped rod 31, forming a mechanical interlock. At this time, the charging cable 2 and the power bank body 1 form a closed-loop structure, which can withstand a tensile force several times the weight of the power bank itself. The charging cable 2 is covered with a metal sleeve 21, which gives the charging cable 2 tensile and bending resistance, thus giving it a lanyard function. At the same time, the triangular guide rod 33 and the inclined surface of the triangular guide groove 32 cooperate to automatically guide the T-shaped rod 31 to align with the notch 28 of the slide plate 23 when inserted, realizing the blind insertion function. When charging is required using the charging cable 2, the pressure plate 29 can be pressed to push the slide plate 23 to compress the spring 26 and slide along the slide groove 22. When the notch 28 aligns with the T-shaped rod 31, since the notch 28 is larger than the size of the T-shaped rod 31, the T-shaped rod 31 loses its constraint and can be pulled out freely to achieve the discharge function. The limiting plate 27 can limit the maximum stroke of the slide plate 23 to ensure that the spring 26 is not over-compressed and causes plastic deformation. Through mechanical structure innovation, this power bank gives traditional power banks new use value without significantly increasing cost and size, and is especially suitable for users who have high requirements for portability and multi-functionality.
