Description

Technical Field

[0001] This utility model relates to the field of power banks, and in particular to a portable power bank. Background Technology

[0002] A portable power bank is a portable energy storage device with a built-in rechargeable battery pack, providing emergency power to mobile electronic devices such as smartphones, tablets, Bluetooth headsets, and smartwatches. Its core function is to output power via USB, Type-C, or wireless charging interfaces, solving the problem of devices being unusable due to depleted battery power. Technically, power banks typically consist of lithium-ion / lithium-polymer batteries, circuit protection modules (such as overcharge / over-discharge protection), voltage conversion chips, and a casing. Capacities are measured in milliampere-hours (mAh) or watt-hours (Wh), with common specifications ranging from 5000mAh (enough to charge a phone 1-2 times) to 30000mAh (supporting multiple devices for extended use). Users can choose between single-port or multi-port output, fast charging protocol compatibility (such as PD, QC), additional functions (such as LED lighting, solar charging), and size and weight (typically 100-500 grams) according to their needs. Due to their lightweight, portability, and plug-and-play characteristics, they have become an essential accessory for modern people's travel, business trips, and outdoor activities, especially significantly improving device battery life in environments without a fixed power source.

[0003] Currently, portable power banks still have several problems that need to be addressed in practical use. One prominent drawback is the lack of adequate protection for the charging port. Because the charging port is constantly exposed to the external environment, it is easily contaminated by dust, water, and other debris during daily use. Dust and water entering the charging port can cause short circuits in the internal circuitry, affecting the power bank's normal charging and discharging functions, and in severe cases, even damaging the internal electronic components and shortening its lifespan. Furthermore, debris entering the port can cause poor contact, preventing the power bank from providing stable power to devices, causing significant inconvenience to users. In addition, the charging port may be damaged by collisions with other objects during transport, further affecting the power bank's performance. Utility Model Content

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.

[0030] like Figures 1-8 As shown, a portable power bank includes a portable power bank body 1 and a back cover 2. A power switch button 3 is located on the left side wall of the portable power bank body 1, and a charging port 4 is located on the right side wall. An indicator light 5 is located at the bottom of the portable power bank body 1, and a wireless charging pad 6 is located on the front wall of the portable power bank body 1. A magnetic bracket 7 is also provided on the outside of the wireless charging pad 6. An earphone charging dock 8 is located inside the rear of the portable power bank body 1, and a [missing information - likely a device or component] is provided inside the earphone charging dock 8. For the Bluetooth headset 9, a protective mechanism 10 is also provided on the outside of the charging port 4. The protective mechanism 10 includes a side plate 13, a guide rod 20, a spring 21, a movable plate 22, and a baffle 25. The side plate 13 is fixedly connected to the right side wall of the portable power bank body 1 by screws 16. Two sets of left and right symmetrical guide rods 20 are fixedly connected inside the side plate 13. The spring 21 is sleeved on the outside of the guide rod 20. The movable plate 22 is movably connected to the guide rod 20 through sliding blocks 23 on both sides. The baffle 25 is fixedly connected to the inner side wall of the movable plate 22.

[0031] like Figures 3-5 As shown, cylindrical positioning protrusions 11 are fixedly installed on the right side wall of the portable power bank body 1, above and below the charging port 4, and threaded holes 12 are provided on the end wall of the positioning protrusions 11. The positioning protrusions 11 and threaded holes 12 enable the side plate 13 to be quickly and accurately positioned during installation, ensuring the accuracy of the installation position and avoiding installation deviation that would cause the protective mechanism 10 to malfunction. At the same time, the threaded connection provides a stable fixing effect, ensuring that the side plate 13 will not loosen or fall off during the use of the power bank, thus improving the stability and reliability of the protective mechanism 10.

[0032] like Figures 3-5 As shown, a set of symmetrical grooves 14 are provided on the side wall of the side plate 13, and a through positioning hole 15 is provided on the bottom surface of the groove 14. The positioning protrusion 11 is inserted into the positioning hole 15. The grooves 14 and the positioning hole 15 enable the side plate 13 to be accurately installed on the power bank body 1, which improves the accuracy and convenience of installation. The through-fitting of the positioning hole 15 and the positioning protrusion 11 further enhances the stability of the side plate 13 installation, reduces the shaking and deviation during the installation process, provides a good foundation for the subsequent fixing of the screws 16, and ensures the overall stability of the protective mechanism 10.

[0033] like Figures 3-5 As shown, screw 16 is threaded together with threaded hole 12 and located in positioning hole 15. By rotating screw 16, it is gradually tightened with threaded hole 12, thereby realizing the fixed connection between side plate 13 and portable power bank body 1.

[0034] like Figure 6 As shown, a socket 17 corresponding to and penetrating the charging port 4 is provided on the side wall of the side plate 13 between the positioning holes 15. The top and bottom surfaces of the socket 17 are respectively provided with inner cavities 18. The inner side walls of the inner cavity 18 are respectively provided with sliding grooves 19. The socket 17 is used to insert the charging cable into the charging port 4. The socket 17 makes it easy to insert the charging cable into the charging port 4 to realize the charging function. The inner cavity 18 provides space for the movement of the movable plate 22 and the baffle 25. The sliding grooves 19 provide a track for the sliding block 23 to slide.

[0035] like Figure 7 and Figure 8As shown, the guide rod 20 is fixedly installed inside the sliding groove 19, and the spring 21 is fitted onto the outside of the guide rod 20. The outer end of the spring 21 is fixedly installed together with the inner end wall of the sliding groove 19. The movable plate 22 is movably installed inside the inner cavity 18, and sliding blocks 23 are fixedly installed on both sides of the movable plate 22. The sliding blocks 23 are movably installed inside the sliding groove 19, and a guide hole 24 is provided on the top surface of the sliding block 23. The sliding block 23 is movably installed together with the guide rod 20 through the guide hole 24, and the inner end of the spring 21 is fixedly installed together with the guide rod 20. The sliding block 23 is fixedly installed together, and the baffle 25 is wedge-shaped and fixedly installed on the inner side wall of the movable plate 22. When the charging cable is inserted into the charging port 4, it will push the baffle 25, causing the movable plate 22 to drive the sliding block 23 to slide along the guide rod 20, compressing the spring 21, thereby exposing the charging port 4. After charging is completed, the charging cable is pulled out, and the elastic force of the spring 21 causes the movable plate 22 to return to its original position, and the baffle 25 covers the charging port 4 again, thereby effectively protecting the charging port 4 and extending the service life of the portable power bank body 1.

[0036] The specific working principle of the protective mechanism 10 in conjunction with the portable power bank body 1 is as follows:

[0037] Install the protective mechanism 10 onto the portable power bank body 1, so that the positioning protrusion 11 on the right side wall of the portable power bank body 1 is inserted into the positioning hole 15 opened on the side wall of the side plate 13. Use an auxiliary tool to thread the screw 16 into the threaded hole 12 opened on the end wall of the positioning protrusion 11 until the screw 16 is placed in the groove 14.

[0038] When the charging port 4 is not in use, the baffle 25 in the protective mechanism 10 is in a closed state under the elastic force of the spring 21. At this time, the outer end of the spring 21 is fixed to the inner end wall of the sliding groove 19, and the inner end is fixed to the sliding block 23. The spring 21 is in a naturally extended state, pushing the movable plate 22 to a suitable position in the inner cavity 18, so that the baffle 25 tightly covers the charging port 4. Since the baffle 25 is fixed on the inner side wall of the movable plate 22, the sliding blocks 23 on both sides of the movable plate 22 are movably installed in the sliding groove 19 and are movably connected to the guide rod 20 through the guide hole 24. The guide rod 20 is fixed in the sliding groove 19, so the baffle 25 can be stably in a closed position, effectively preventing dust, water stains, debris, etc. from entering the charging port 4, avoiding short circuits in the internal circuit due to dust and water stains, preventing poor contact caused by debris, ensuring the stability of the normal charging and discharging function of the power bank, and extending the service life of the internal electronic components of the power bank. At the same time, the baffle 25 can also play a buffer role, reducing the damage to the charging port 4 caused by collisions with other items during carrying.

[0039] When charging port 4 is needed, the user inserts the charging cable into socket 17 and pushes it towards charging port 4. The charging cable will contact baffle 25. Since baffle 25 is wedge-shaped, the charging cable can smoothly push baffle 25. Baffle 25 drives movable plate 22 to move within inner cavity 18. Sliding blocks 23 on both sides of movable plate 22 slide along sliding groove 19 on guide rod 20, simultaneously compressing spring 21. As movable plate 22 moves, baffle 25 will gradually enter inner cavity 18, gradually exposing charging port 4. The charging cable can then be smoothly inserted into charging port 4 for charging. During charging... Spring 21 is always in a compressed state, applying elastic force to sliding block 23. However, due to the obstruction of the charging cable, movable plate 22 and baffle 25 remain in their current positions. When charging is complete, the user unplugs the charging cable. At this time, the elastic force of spring 21 begins to take effect, pushing sliding block 23 to slide along sliding groove 19 on guide rod 20 towards charging port 4. Sliding block 23 drives movable plate 22 to move within inner cavity 18. Movable plate 22 then drives baffle 25 to reset, tightly blocking charging port 4 again. The whole process is flexible and smooth, without hindering the charging operation, thus improving the user experience.

[0040] The indicator light 5 shows whether the portable power bank 1 is fully charged and its power consumption. When the portable power bank 1 is fully charged and the user needs to use it to charge a mobile phone, the user turns on the portable power bank 1 by pressing the power switch button 3. The user then places the mobile phone (with a wireless charging and magnetic charging case) in the center of the wireless charging pad 6. The magnetic bracket 7 then magnetically attaches the mobile phone, and the wireless charging pad 6 wirelessly charges the phone. When the user needs to charge the mobile phone via a data cable, the user connects the data cable to one charging port 4 of the power bank and the other charging port 4 of the mobile phone for wired charging. This charging port 4 is a common Type-C to Lightning data cable, supporting mainstream mobile phones such as Huawei, Samsung, and Apple. When the user needs to charge the Bluetooth headset 9, the user opens the snap-fit ​​back cover 2 and places the Bluetooth headset 9 into the headset charging dock 8 for charging.
