Description

Technical Field

[0001] This utility model relates to the field of shared power bank technology, specifically a shared power bank with LED backlight. Background Technology

[0002] Shared power banks are portable charging devices. Their main function is to provide power to smartphones or other mobile devices carried when out and about. Users can rent them in public places (such as shopping malls, airports, and train stations) and pay by time or number of uses. This convenient device solves the problem of not being able to charge one's phone when it is low on battery.

[0003] Traditional shared power banks can overheat their internal batteries after prolonged use, leading to battery aging, performance degradation, and reduced charging efficiency. Users may experience insufficient power. This invention adds multiple heat dissipation plates inside and promotes heat dissipation to the surrounding environment through heat dissipation holes, thereby reducing the internal temperature of the device and improving battery life. For this purpose, we propose a shared power bank with LED backlight. Utility Model Content

The heat sinks on the first heat sink 2 and the lithium battery 3 are vertically distributed, corresponding to the first protective shell 1 and the second insulating plate 11. The heat dissipation holes 12 and 18 on the back of the protective shell 5 promote heat diffusion to the surrounding environment through the contact surface area between the heat dissipation holes 12 and 18 and the air, thereby reducing the internal temperature of the device, maintaining the stability of the device, preventing overheating, ensuring that the lithium battery 3 operates within a safe temperature range, and avoiding performance degradation caused by overheating. The heat sinks on the first heat dissipation plate 2 and the second heat dissipation plate 4 serve as a passive cooling system, eliminating the need for active cooling devices such as fans, thereby reducing noise levels and improving user experience. An LED display screen 9 is installed on the outer side of the first protective shell 1. The LED display screen 9 is used to display the power status, charging status, or other prompt information. The LED display screen 9 is switched on and off and its brightness is adjusted automatically according to the power level through the control circuit.
