Subsequent technological innovations have made charging mobile phones, tablets, and other devices much easier, significantly improving user convenience and the energy density, volume, and battery life of portable devices. However, continuous improvements in portability and other aspects of the manufacturing process have significantly enhanced the user experience. However, behind these advancements, the assembly quality of power banks and the stability of their assembly have a significant impact on product reliability.

[0003] Utility model patent number CN212393104U discloses a mounting structure for a portable power bank, comprising a power bank body and a steel wire. The power bank body has a first receiving groove formed on its outer surface, a spring clip mounted within the first receiving groove and fixedly connected to the power bank body. The spring clip has a connection groove formed at its top end, a fixed shaft mounted within the connection groove, and the fixed shaft is fixedly connected to the spring clip. Sealing covers are mounted on the left and right outer sides of the power bank body, and a second receiving groove is formed on the inner wall of the sealing cover, with the steel wire mounted within the second receiving groove.

[0034] A mobile power supply with adhesive structure, referring to Figure 1 and Figure 2 , including an installation box 1 and a power supply assembly 2, and the power supply assembly 2 is installed in the installation box 1. The edges and corners of the installation box 1 are all rounded, which makes the mobile power supply more convenient to hold and carry. The installation box 1 includes a box cover 11 and a box body 12. The box cover 11 can cover the box body 12 to form a sealed installation box 1. After the power supply assembly 2 is installed inside the box body 12, the box body 12 is sealed and installed through the installation box 1 cover, so that the mobile power supply can be used stably as a whole. The edge of the bottom surface of the box cover 11 is provided with a connecting strip 13 extending toward the box body 12, and the inner edge of the box body 12 is provided with a connecting groove 14 with an upward opening. When the box cover 11 and the box body 12 are closed, the connecting strip 13 is inserted into the connecting groove 14, so that the box body 12 and the box cover 11 are accurately connected. Connecting strip 13 is positioned slightly inward at the bottom edge, with connecting groove 14 positioned on the inside. This conceals the strip and groove when lid 11 and body 12 are connected, enhancing the overall aesthetics. An adhesive layer 15 is provided at the bottom of groove 14. Once inserted into groove 14, connecting strip 13 contacts adhesive layer 15, bonding it to the groove. This allows for quick connection and securement of the mounting box 1, improving the manufacturing efficiency of the power bank.

[0035] Reference Figure 3 and Figure 4 The power supply assembly 2 is located in the installation box 1 and includes a battery cell 21, a circuit board 22, an electrical interface 23, and a button 24. There are two battery cells 21, and the battery cells 21 are connected to a current collector 25. After the two battery cells 21 are connected through the current collector 25, they are connected to the circuit board 22. The circuit board 22 is connected to an electrical interface 23 and a button 24. There are three electrical interfaces 23, including two different types of electrical interfaces 23, which improves the charging efficiency and compatibility of the mobile power supply and can charge a greater number and variety of devices at the same time. The box body 12 is provided with a connection port 16 and a button port 17. The electrical interface 23 corresponds to the connection port 16, and the button 24 corresponds to the button port 17, making the use of the mobile power supply more convenient.

[0036] Reference Figure 3 and Figure 4 The box body 12 is provided with a connecting rod 18, which supports the connecting circuit board 22, ensuring its stable installation within the mounting box 1. However, the inner wall of the box body 12, corresponding to the connecting rod 18 and the connecting port 16, is not provided with a connecting groove 14, preventing the connecting groove 14 from interfering with the connection between the connecting rod 18 and the circuit board 22, or between the connecting port 16 and the electrical interface 23. A cushion is provided on the surface of the battery cell 21 near the mounting box 1 to cushion the impact of the external side of the mounting box 1 on the battery cell 21, ensuring its protection during use.

[0037] The working principle of the embodiment of the present application is as follows: by providing a connecting strip 13 on the bottom edge of the box cover 11 and a connecting groove 14 on the inner edge of the box body 12, when the box cover 11 closes the box body 12, the connecting strip 13 can fit into the connecting groove 14, thereby ensuring the accurate connection between the box cover 11 and the box body 12. Furthermore, an adhesive layer 15 provided in the connecting groove 14 fixes the connecting strip 13 inserted into the connecting groove 14, thereby firmly connecting the box cover 11 and the box body 12. The combination of the connecting strip 13, the connecting groove 14, and the adhesive layer enables the installation box 1 to be quickly and conveniently fixed, thereby improving the production efficiency of the mobile power supply.
