Secondly, the Bluetooth receiving module has the advantages of low power consumption and high compatibility, and has become one of the preferred solutions for modern wireless communication. Through Bluetooth connection, the power bank can easily be paired with smart phones, tablet computers and other smart devices, realize fast transmission of pattern customization signals, and simplify the operation process. In the embodiment, a Bluetooth receiving module is used.

[0030] Preferably, the Bluetooth receiving module as the receiving unit 2 is arranged on the circuit board 3. This layout has multiple advantages: first, the Bluetooth receiving module has ready-to-use products available, and the structure is relatively simple compared to the antenna of NFC transmission, further simplifying the internal structure of the power bank and reducing the connection lines between components, thereby reducing production costs and assembly difficulty. Second, the circuit board as the core control unit of the power bank, its stability and reliability directly affect the performance of the entire product. Integrating the receiving unit directly on the circuit board can ensure the accuracy and efficiency of signal transmission, reducing the possibility of signal attenuation and interference. Finally, from the maintenance point of view, the integrated design of the receiving unit and the circuit board also facilitates troubleshooting and maintenance work during production.

[0031] Preferably, the display screen 1 is an LED display screen. LED display screen has the characteristics of high brightness and high contrast, even in outdoor strong light environment can clearly display patterns or information, ensures that users in different scenes can obtain good visual experience. Second, LED display screen has the advantages of low power consumption and long service life, which can significantly reduce the energy consumption of the power bank, prolong its battery life, and reduce the frequency of replacing the display screen, reducing the use cost. In addition, the LED display screen also supports multiple color display, which can customize different color schemes according to the user's preferences and needs, further improving the individuality of the power bank. Furthermore, the response speed of the LED display screen is fast, which can update the display content in real time, ensuring that users can see the changes of the customized patterns in time.

The combination of the touch upper shell and the display screen greatly improves the convenience and intuitiveness of user operation. Users can directly control the functions of the power bank by touching specific areas on the upper shell, thereby simplifying the operation process. Secondly, the conductive glue has good conductivity and adhesion, and can accurately transmit the electrical signals generated by user touch to the display screen, achieving fast response. In addition, this design also enhances the stability and durability of the display screen. The display screen is tightly attached to the inner side of the upper shell and is fixed by conductive glue, avoiding the problem of loosening or falling off due to external impact or long-term use. Finally, from the perspective of user experience, the combination of the touch upper shell and the display screen makes the appearance of the power bank more simple and fashionable, meeting the aesthetic needs of modern people.

[0034] Preferably, the magnetic attraction piece 7 is further included, the housing 4 is provided with a containing portion 44 containing the magnetic attraction piece 7, and the magnetic attraction piece 7 is located in the containing portion 44. The application of the magnetic attraction piece greatly facilitates the connection of the power bank with other devices. Through the magnetic attraction force, the power bank can be easily adsorbed on mobile phones, tablets and other devices, realizing fast charging or data transmission, without worrying about the problem of cable entanglement or interface mismatch. This design not only improves the convenience of user experience, but also reduces the wear and tear of the interface caused by plugging and unplugging the cable. Secondly, the use of the magnetic attraction piece also enhances the safety of the power bank. During charging or data transmission, the magnetic attraction piece can maintain a stable connection state, avoiding the problem of accidental power failure or data loss caused by loose or falling cable. In addition, the design of the magnetic attraction piece also considers the aesthetics and practicality. The containing portion makes the magnetic attraction piece perfectly integrated into the overall appearance of the power bank, without being conspicuous or affecting the aesthetics.

[0035] Preferably, the housing 4 is further provided with a coil 5 and a magnetic separation sheet 6, the coil 5 is electrically connected with the circuit board 4, the magnetic separation sheet 6 is located on the side of the coil 5 away from the magnetic attraction piece 7, and the coil 5 and the magnetic separation sheet 6 are adhesively connected. The setting of the magnetic separation sheet effectively solves the problem of magnetic field interference that may occur during wireless charging. The magnetic separation sheet can guide the magnetic field, so that the magnetic field energy of the wireless charging transmitting end is more concentratedly transmitted to the receiving end, i.e. the power bank or mobile phone and other devices. This can improve the electromagnetic induction strength, so that the receiving end coil can more effectively capture energy, thereby converting it into electric energy and improving the charging efficiency. Wireless charging relies on the principle of electromagnetic induction, but strong magnetic field may interfere with other electronic elements inside the power bank, affecting the performance and stability of the power bank. Reducing the influence on other components in the power bank can avoid unnecessary heating and ensure the stability and safety of the power bank.

[0036] Preferably, the shell 4 is further provided with a non-slip pad 8 on one side of the magnetic member 7. The material of the non-slip pad generally has a high friction coefficient, which can effectively increase the friction between the power bank and the adsorption surface, prevent the power bank from slipping or falling off during use, and thus ensure the safety and stability of use.
