[0036] In one embodiment, the U-shaped bracket 80 has pin ends 81 on both sides, and the card cover 20 has mounting holes 21 corresponding to the pin ends 81.

[0037] Specifically, the pin ends 81 are designed on both sides of the U-shaped bracket 80, while the card cover 20 has mounting holes 21 corresponding to the pin ends 81. This design allows the U-shaped bracket 80 to be connected to the mounting holes 21 on the card cover 20 via the pin ends 81, thereby securing the two together. Furthermore, pin connections typically offer high stability and reliability, capable of withstanding certain external forces and torques; therefore, this design ensures that the U-shaped bracket 80 will not detach or loosen due to external forces during unfolding or use, guaranteeing the overall stability and safety of the product.

[0038] In one embodiment, the U-shaped bracket 80 is made of metal.

[0039] Specifically, metal materials typically possess high strength and hardness, allowing the U-shaped bracket 80 made of metal to withstand greater weight and pressure. Furthermore, metal materials exhibit excellent durability and fatigue resistance, maintaining their shape and performance over extended periods without easily aging or wearing down. This enables the U-shaped bracket 80 to withstand prolonged use and frequent adjustments. Additionally, the smooth, glossy surface of metal materials typically lends the product a noble and elegant appearance, making the U-shaped bracket 80 more visually appealing and enhancing its overall aesthetics. Moreover, using metal to construct the U-shaped bracket 80 elevates the product's perceived quality and grade, making it more competitive in the market. This helps attract consumers who pursue a high-quality lifestyle and increases product sales.

[0040] In one embodiment, the side of the main body 10 is also provided with an indicator light, which is electrically connected to the PCB circuit board 60.

[0041] Specifically, the indicator light uses different flashing patterns or color changes to intuitively display the remaining battery level of the power bank. This allows users to quickly understand the battery status without complicated operations or checking the screen, enabling them to charge the power bank in time or adjust their usage strategy accordingly. Furthermore, the intuitive battery display helps users better plan their usage time and avoid disruptions due to insufficient battery power; this also enhances the overall user experience.

In addition, by integrating the display module, the power bank not only possesses basic charging functions but also provides additional features such as battery level display and charging status indication, making the product more practical and convenient, and meeting diverse user needs.

[0046] In one embodiment, the side of the main body 10 is also provided with a charging interface, which is electrically connected to the PCB circuit board 60.

[0047] Specifically, the charging port is a key component connecting the power bank to an external power source, allowing users to charge the power bank's battery cells 30 by connecting a charger or device such as a computer. Furthermore, the charging port design allows users to charge the power bank anytime, anywhere, without needing to search for specific charging equipment or locations. Most power banks use standard charging ports such as Micro USB and Type-C, making it easy for users to find compatible chargers.

[0048] In one embodiment, the main body 10 is composed of a front shell 11 and a bottom shell 12, and the card cover 20 is connected to the bottom shell 12.

[0049] Specifically, the combined design of the front cover 11 and the bottom cover 12 makes the main body 10 structure more stable, able to withstand certain external impacts and pressures, protecting the internal electronic components from damage. Furthermore, the front cover 11 and the bottom cover 12 are typically connected using snap-fit ​​or screw connections, making the assembly process simpler and faster. This design also facilitates subsequent disassembly and maintenance; when internal components malfunction, the front cover 11 and the bottom cover 12 can be easily opened for inspection or replacement. Additionally, the card cover 20, attached to the bottom cover 12, protects the card from external environmental interference and damage, such as scratches and contamination.

[0050] The Bluetooth module 70 and the display module use existing publicly available technologies, which will not be elaborated on here.
