The technical solutions of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.
[0028] Example 1: The power bank component 1 of this multi-functional power bank is formed by a lower housing 11 and an upper housing 12 fastened together and secured with four screws to form a stable overall structure. The upper surface of the lower housing 11 has a battery slot 13 with six recesses for holding six lithium batteries 16, providing long-lasting power to the device. The upper surface of the upper housing 12 has six recesses for embedding and fixing six solar panels 2, which can charge the lithium batteries 16 under sunlight. A charging panel 14 is located at the front of the lower housing 11 and the upper housing 12, and has three charging and discharging ports 15, including USB-A, USB-C, and Micro USB ports, to meet the charging needs of different devices. A wireless Bluetooth module 18 is fixed to the rear side of the upper surface of the lower housing 11, enabling wireless audio transmission. The rear surfaces of the lower housing 11 and the upper housing 12 have four openings for embedding and fixing four full-range speakers 19, and a notch for embedding and fixing an RGB LED light panel 17. The power supply end of the RGB LED light panel 17 is connected to the power output end of the lithium battery 16. A button for controlling the RGB LED light panel 17 to light up or turn off is fixed on the rear end face of the upper housing 12 for user convenience.
[0029] The strap assembly 3 includes a right elastic fabric 31 fixed to the right side of the lower housing 11 and a left elastic fabric 32 fixed to the left side. Both are sewn with Velcro 33 on both sides. Through the mutual adhesion of the Velcro 33, the right elastic fabric 31 and left elastic fabric 32 can be flipped downwards and adhered together to securely fasten the power bank to a backpack, arm, or other location; alternatively, the right elastic fabric 31 and left elastic fabric 32 can be folded upwards and adhered to cover and protect the solar panel 2. A charging controller compatible with the solar panel 2 is installed at the rear of the inner cavity of the lower housing 11 to ensure the stability and efficiency of solar charging.
[0030] Example 2: The multi-functional power bank in this example is structurally similar to Example 1, but with some optimizations. The power bank assembly 1 is also formed by a lower housing 11 and an upper housing 12 fastened together, secured with six screws to improve the overall structural stability. The battery slot 13 has eight recesses for holding eight lithium batteries 16, increasing the power bank's capacity. Eight solar panels 2 are embedded and fixed on the upper surface of the upper housing 12 to improve solar charging efficiency. The charging panel 14 has four charging and discharging ports 15, including two USB-A ports, one USB-C port, and one Lightning port, meeting the charging needs of more devices. Six openings are provided on the rear surfaces of the lower housing 11 and the upper housing 12 for embedding and fixing six full-range speakers 19, providing stronger audio output capabilities. The brightness of the RGB LED light panel 17 is adjustable, with multi-level brightness adjustment via buttons on the rear surface of the upper housing 12 to meet lighting needs in different environments. The right elastic fabric 31 and left elastic fabric 32 of the strap assembly 3 are made of softer materials to improve wearing comfort.
[0031] Example 3: This example of a multi-functional power bank further expands its functionality. After the lower housing 11 and upper housing 12 of the power bank component 1 are fastened together, they are treated with waterproof structures such as sealing strips to achieve an IPX7 waterproof standard, suitable for harsh outdoor environments. The battery slot 13 has seven recesses designed to hold and fill seven lithium batteries 16, balancing power storage and size / weight. Seven solar panels 2 are embedded and fixed on the upper surface of the upper housing 12, using high-efficiency monocrystalline silicon solar panels to improve charging efficiency. The charging panel 14 has five charging and discharging ports 15, including three USB-A ports, one USB-C port, and one wireless charging module, meeting the needs of wireless charging devices. Five openings are provided on the rear surfaces of the lower housing 11 and upper housing 12 for embedding and fixing five full-range speakers 19, providing a more immersive audio experience. The RGB LED light panel 17 uses RGB LED beads, and the color can be adjusted via a button on the rear surface of the upper housing 12 to create different atmospheres. Hooks are added to the right elastic fabric 31 and left elastic fabric 32 of the strap assembly 3 for easy hanging of items such as keys and small tools. A smart charging controller is installed at the rear of the inner cavity of the lower housing 11, which can automatically adjust the charging strategy according to the power of the lithium battery 16 and the charging status of the solar panel 2 to extend battery life.
[0032] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:
[0033] Users connect an external power source (such as a charger or computer USB port) via the charging / discharging interface 15 of the charging panel 14. The current, after being regulated by the charging controller, is delivered to the lithium battery 16 in the battery compartment 13. The charging controller monitors the battery voltage and temperature in real time to prevent overcharging or overheating. When the solar panel 2 is exposed to sunlight, the photovoltaic effect generates current, which is converted by the charging controller into a voltage suitable for the lithium battery before being stored. The charging controller prioritizes solar power, charging the battery with any remaining charge; if sunlight is insufficient, it automatically switches to external power or battery power.
[0034] Users connect the device requiring power via charging / discharging interface 15. The lithium battery 16 outputs current after being regulated by the charging controller, supporting simultaneous power supply from multiple interfaces. When equipped with a wireless charging module, it can charge compatible devices via electromagnetic induction. After the wireless Bluetooth module 18 is paired with devices such as mobile phones and tablets, the audio signal is decoded by the module and transmitted to the full-range speaker 19 to achieve stereo playback. Users press the control button at the rear of the upper housing 12 to trigger the RGB LED light panel 17 to light up; if it is an adjustable brightness model, a long press of the button can cycle through multiple brightness levels; if it is an RGB model, a short press of the button switches the color mode. The LED power is directly supplied by the lithium battery 16, and the controller can ensure automatic shutdown when the battery is low to protect the battery. The right elastic fabric 31 and the left elastic fabric 32 are attached and fixed around the target object (such as a backpack strap or arm) using Velcro 33.
[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
