Description

Technical Field

[0001] This utility model relates to the field of mobile power technology, specifically to a power box structure for an energy storage mobile power supply. Background Technology

[0002] In today's digital age, the widespread use of portable electronic devices such as smartphones, tablets, and smart wearables has led to a continuous increase in the market demand for power banks. Users' requirements for the functionality, performance, and cost of power banks are showing a significant trend of diversification, but existing power bank products have many shortcomings in meeting these needs. From a user needs perspective, different user groups have drastically different demands for power banks. Some consumers pursue ultimate performance, expecting power banks with high capacity, high output power, and fast charging capabilities to meet their needs for frequently using high-performance devices (such as gaming phones and professional photography equipment). However, these high-performance power banks often use high-end battery cells and complex circuit designs, which are not only expensive but also have significant heat dissipation issues due to their high power density, posing stability risks during prolonged use. Another group of users prioritizes stability, especially in outdoor work and emergency rescue scenarios, requiring power banks to operate reliably under complex environmental conditions (such as high temperature, low temperature, and vibration) to ensure continuous power supply to devices. However, existing general-purpose power banks fall short of professional-grade standards in terms of protection performance and environmental adaptability. In addition, there are a large number of price-sensitive consumers who prefer cost-effective and practical power banks, hoping to obtain devices that meet their basic charging needs at a lower cost. However, current power bank products on the market either sacrifice performance and quality to reduce costs or significantly increase prices in pursuit of high performance, making it difficult to strike a balance between performance, quality, and price, and thus failing to effectively meet the needs of this group of consumers. From a manufacturing perspective, to meet the diverse user needs mentioned above, manufacturers often need to produce multiple models of power banks. Different models differ in battery cell specifications, circuit design, and casing structure, significantly increasing the complexity of the production line. This increased complexity not only requires more production equipment and human resources but also increases the difficulty of production management and quality control, leading to a significant rise in production costs. Simultaneously, managing inventory across multiple models presents challenges, potentially resulting in unsold stock and excess inventory for some models, further driving up operating costs.

[0025] Working Principle: In the battery pack power supply stage, the battery compartment 5 inside the power supply box undertakes the core energy storage function. Multiple parallel battery mounting slots 14 are set inside the compartment, allowing users to select compatible rechargeable batteries according to their needs, such as common 18650 batteries and their high-performance variants (MJ1, 35E, etc.). After the batteries are installed in the slots, the energy is delivered to the charging / discharging board 4 via two sets of lead wires 15. The charging / discharging board 4 acts as the energy conversion and control center, and its integrated charging / discharging control chip (such as IP5306, SW6306V, etc.) plays a crucial role. When an external device is connected to the power bank through the USB-type-C discharge interface 10 of the interaction section 3, the charging / discharging control chip activates the boost conversion function, converting the low-voltage DC power output from the battery pack into a 5V standard voltage through the internal DC-DC boost circuit, and then stably outputting it to the device via the interface. During charging, an external power source inputs power through the USB-Type-C charging port 9. The chip first detects and filters the input voltage to ensure stable power quality. Then, it uses a constant current-constant voltage (CC-CV) charging mode to charge the battery pack: initially, it charges rapidly with a constant current, and when the battery voltage approaches the full charge threshold (approximately 4.2V), it automatically switches to constant voltage mode to avoid overcharging risks until the battery is fully charged. The box structure plays a crucial role in ensuring stable system operation. The upper cover 1 and lower cover 2 are hinged for opening and closing. Users can easily open the box by applying force through the trapezoidal structure formed by the first inner bevel notch 16 and the second inner bevel notch 17 at the opening convenience port 7. After opening, users can freely replace the battery pack or charging / discharging board to meet individual needs. When closed, the male and female connecting fasteners 18 of multiple sets of movable fasteners 8 interlock with each other, and together with the limiting structure at the hinge, ensure that the box remains firmly closed during transportation or use. The anti-loosening cover 6 is made of flexible silicone, which fits tightly against the battery pack surface after the box is closed. Its elastic deformation fills the gap between the battery and the compartment, preventing battery displacement due to vibration. Simultaneously, the excellent thermal conductivity of silicone quickly conducts the heat generated by the battery during operation to the box surface. Combined with the heat dissipation capacity of the PVC shell, this effectively reduces battery temperature, ensuring operation within a safe operating temperature range. User interaction is implemented by the interaction unit 3. When the power bank is charging, current flows into the charging / discharging board 4 through the charging interface 9, illuminating the LED indicator 11 connected to the main charging circuit, visually indicating normal charging operation. During discharging, users can determine the power bank's operating status by observing the charging prompts on the device, eliminating the need for additional indicator lights. Furthermore, the charging interface 9 and discharging interface 10 adopt the USB-type-C universal standard, supporting reversible insertion and compatibility with mainstream electronic devices. Combined with the intelligent identification function of the charging / discharging control chip, it can automatically adapt to the charging protocols required by the device (such as PD, QC, etc.) for efficient charging.
