[0016] Appendix Figure 1 This is a schematic diagram of the structure combining a flexible PCB board and a flexible LED digital tube for displaying multi-form information, as shown in Embodiment 1 of this application. Detailed Implementation
[0017] The following will be combined with the appendix Figure 1 The technical solutions in the embodiments of this utility model are clearly and completely described herein. The described embodiments are only possible technical implementations of this utility model and not all possible implementations. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of this utility model without creative effort, and these embodiments are also within the protection scope of this utility model.
[0018] The inventors of this application discovered that existing power banks only make simple improvements to their appearance, lacking breakthroughs in structural shape or display methods. Therefore, this application primarily uses flexible materials to fabricate the PCB board, enabling it to be bent, folded, and even rolled up to adapt to more diverse application scenarios. This design, utilizing a flexible PCB board and flexible LED digital tubes, achieves highly flexible and diverse display effects, thus solving the problem of the limited display methods in traditional power banks. The following is a further detailed description of this application.
[0019] Example 1
[0020] The deformable mobile power supply with multi-form display information provided in this application embodiment includes a flexible PCB board and a flexible LED digital tube. The flexible PCB board is used to carry electronic components and can be bent, folded, or rolled up to adapt to more diverse application scenarios. The flexible LED digital tube is mounted on the flexible PCB board and is used to display the current battery level and fast charging status.
[0021] Specifically, a flexible PCB consists of a substrate layer, a conductive layer, and a cover film. The substrate layer can be polyimide (PI) or other materials with good flexibility, while the conductive layer uses copper foil with a thickness of approximately 18μm to 35μm. The cover film provides insulation and protection, and commonly used materials include acrylic resin and epoxy resin. Alternatively, transparent conductive materials, such as ITO (indium tin oxide), can be used to enhance the display effect.
[0022] The manufacturing process of flexible PCBs utilizes laser cutting and thermoforming technologies. Laser cutting allows for precise cutting to the desired shape and size, while thermoforming sets the PCB at high temperatures, ensuring its stability after repeated bending. Furthermore, the flexible PCB undergoes surface gold plating, enhancing soldering reliability and corrosion resistance.
[0023] Flexible LED digital tubes are fixed to a flexible PCB board through a curing process. This curing process can be achieved using UV-cured adhesives, which offer excellent bonding strength and weather resistance, maintaining stable performance in various environments. Alternatively, hot melt adhesives or double-sided tape can also be used for fixing; these methods can also meet the needs of different application scenarios.
[0024] The structural design of flexible LED digital tubes is also crucial. It consists of multiple LED beads, each connected by tiny wires to form a complete display unit. The choice of LED beads is also important; common colors are red, green, and blue, which can be combined according to specific needs. Furthermore, there are various packaging forms for the LED beads, such as SMD (Surface Mount Device) and DIP (Dual In-line Package), each with its own unique advantages and disadvantages, allowing for selection based on specific requirements.
[0025] The display interface of flexible LED digital tubes can be designed in various ways to suit different application scenarios. For example, in outdoor sports scenarios, brighter red and green lights can be selected to ensure clear visibility even in strong light; while in indoor office scenarios, soft blue lights can be chosen to reduce eye strain. Furthermore, dynamic display effects, such as scrolling text and animations, can be achieved through programmable control, enhancing the user experience.
[0026] The connection between the flexible PCB board and the flexible LED digital tube is also crucial. They are connected by conductive cables, typically flat cable (FFC) or flexible printed circuit (FPC). Both of these connection methods offer excellent flexibility, allowing them to withstand frequent bending and twisting. Furthermore, the connection reliability can be improved by reinforcing the connection with solder joints.
[0027] The implementation principle of this embodiment is as follows:
[0028] Through the rational design and manufacturing of flexible PCB boards and flexible LED digital tubes, the power bank achieves high flexibility and versatility. The flexible PCB board can withstand multiple bends without damage and adapt to various complex installation environments, greatly expanding the application range of the power bank. Meanwhile, the introduction of flexible LED digital tubes makes the information display of the power bank more intuitive and diverse, enhancing the user experience. Furthermore, this design also reduces production costs to some extent, improving the product's market competitiveness.
[0029] Example 2
[0030] The difference between this embodiment and the previous one is that a control circuit consisting of a SOC architecture, an MCU, and a battery protection chip is added and integrated onto a flexible PCB board. This improvement gives the power bank stronger data processing capabilities and more comprehensive protection functions.
[0031] Specifically, a System-on-a-Chip (SoC) architecture is an integrated circuit that combines a processor, memory, input / output interfaces, and other functions into a single unit, suitable for high-performance computing and data processing tasks. The Microcontroller Unit (MCU) coordinates the work of each module, achieving efficient energy management. Battery protection chips are primarily used to monitor the battery's status and prevent overcharging, over-discharging, and other problems.
[0032] At the heart of the SOC architecture is a high-performance ARM Cortex-M series processor with a clock speed of up to 168MHz, built-in high-speed cache, and low-power mode to effectively reduce energy consumption. In addition, it is equipped with a rich set of peripheral interfaces, such as SPI, I2C, and UART, facilitating communication with other modules.
[0033] The MCU used is an STM32 series microcontroller, which features powerful real-time processing capabilities and low power consumption. It can monitor battery parameters such as voltage and current in real time and adjust the charging and discharging process according to preset algorithms to ensure safe battery operation. Furthermore, the MCU supports multiple communication protocols, such as Bluetooth and Wi-Fi, facilitating remote management and control.
[0034] The battery protection chip used is the TI TPS25980, a high-performance lithium-ion battery protection chip that provides overcurrent protection (OCP), overvoltage protection (OVP), and short-circuit protection. When an abnormality is detected, the protection chip immediately cuts off the circuit to prevent danger.
[0035] The implementation principle of this embodiment is as follows:
[0036] By introducing an advanced SOC architecture, MCU, and battery protection chip, the intelligence and safety of the power bank have been significantly improved. The powerful computing capabilities of the SOC architecture enable the power bank to better adapt to complex data processing tasks, while the efficient energy management of the MCU extends battery life and reduces maintenance costs. The addition of the battery protection chip provides users with comprehensive safety protection, eliminating potential risks. Overall, this improvement not only enhances product performance but also delivers a better user experience.
[0037] Example 3
[0038] The difference between this embodiment and the previous one is that it adds a Lightning interface and a USB-C interface, supporting multiple protocol input / output, including PD, QC2.0, QC3.0, AFC, and FCP. This improvement gives the power bank stronger compatibility and faster charging speed.
[0039] Specifically, both the Lightning and USB-C ports use high-quality metal contacts with low contact resistance and high wear resistance. The Lightning port is commonly used in Apple devices and supports reversible insertion for user convenience. The USB-C port is widely used in various smart devices, supporting power transmission up to 100W to meet the charging needs of high-power devices.
[0040] The power bank supports multiple input / output protocols including PD (Power Delivery), QC2.0 (Quick Charge 2.0), QC3.0 (Quick Charge 3.0), AFC (Adaptive Fast Charging), and FCP (Fast Charging Protocol). These protocols each have different characteristics and technical specifications, but they can all significantly improve charging speed and efficiency.
[0041] The PD protocol is a standard developed by the USB-IF organization, supporting a maximum power transfer of 100W and enabling fast charging between various devices. QC2.0 and QC3.0 are fast charging protocols introduced by Qualcomm, supporting maximum charging powers of 18W and 36W respectively. AFC is an internationally used fast charging protocol, supporting a maximum charging power of 15W. FCP is a domestically developed fast charging protocol, supporting a maximum charging power of 18W.
[0042] The implementation principle of this embodiment is as follows:
[0043] By adding Lightning and USB-C ports and supporting multiple fast charging protocols, the compatibility and charging speed of the power bank have been greatly improved. Regardless of the type of device used, users can find a suitable charging port and protocol to enjoy a convenient and efficient charging experience. Furthermore, support for multiple protocols helps extend battery life and reduce damage caused by overcharging. In short, this improvement not only enhances the product's functionality but also brings greater convenience to users.
[0044] Example 4
[0045] The difference between this embodiment and the previous one is the addition of OCP, OVP, and short-circuit output protection functions to ensure the safe operation of the power bank under extreme conditions. This improvement aims to enhance product reliability and user peace of mind.
[0046] Specifically, OCP (Over Current Protection) refers to overcurrent protection; when the detected current exceeds a set value, the protection circuit will immediately disconnect to prevent the circuit from burning out due to excessive current. OVP (Over Voltage Protection) refers to overvoltage protection; when the detected voltage exceeds a set value, the protection circuit will also disconnect in time to prevent safety accidents caused by excessive voltage. Short circuit protection quickly cuts off the power supply when a short circuit is detected at the load end, avoiding serious consequences such as fires.
[0047] To achieve these protective functions, we have incorporated dedicated protection circuitry within the power bank. This circuitry typically consists of precision components such as resistors, capacitors, diodes, and MOSFETs, employing a combination of hardware circuitry and software algorithms to provide accurate protection. Furthermore, periodic self-testing and fault alarm mechanisms proactively detect potential problems, ensuring the product is always in optimal working condition.
[0048] The implementation principle of this embodiment is as follows:
[0049] By adding OCP, OVP, and short-circuit output protection functions, the power bank possesses comprehensive safety protection measures, enabling it to operate normally under various extreme conditions. This is crucial for users, as it not only protects the device itself from damage but also prevents safety accidents caused by unforeseen circumstances. This improvement undoubtedly provides additional safety for users who frequently carry power banks. Overall, this improvement not only enhances product reliability but also brings users greater peace of mind.
[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
