Description

Technical Field

[0001] This utility model relates to the field of portable power banks, and in particular to a foldable multi-interface portable power bank. Background Technology

[0002] A portable power bank is a portable power supply device that integrates energy storage, voltage boosting, and charging management functions. This device primarily provides backup power for mobile electronic devices such as smartphones, laptops, tablets, digital cameras, and camcorders, combining the dual functions of a charger and a backup battery.

[0003] Portable power banks typically feature high capacity, multi-functionality, compact size, long lifespan, and stable operation. Their capacities range widely, from 2000mAh to 20000mAh, and even higher capacities are available on the market. High-capacity power banks can provide extended power to devices such as laptops, while lower-capacity ones are primarily used for charging small digital devices like mobile phones. Power banks are designed for portability; their compact size allows users to easily place them in a backpack or pocket, fulfilling their need to charge mobile devices anytime, anywhere.

[0004] Furthermore, portable power banks come equipped with various power adapters and USB ports, ensuring compatibility with diverse charging interfaces and protocols, making them suitable for a wide range of mobile devices from various brands and models. This eliminates user concerns about power bank compatibility with their devices. Many power bank products also support fast charging technology, significantly improving charging convenience and efficiency.

[0005] In practical applications of portable power banks, the use of fast charging technology does indeed present a problem of high heat dissipation. Fast charging technology achieves rapid charging by increasing voltage or current, but this also causes internal components (such as battery cells and circuit boards) to operate under high load, easily leading to overheating. If the power bank's heat dissipation design is inadequate, the internal temperature will rise rapidly, potentially causing safety hazards such as short circuits, bulging, or even explosions. This is especially true when multiple ports are used simultaneously, as the power bank needs to power multiple devices at the same time, further increasing the load and making the heat dissipation problem even more pronounced.

[0006] Furthermore, the quality of battery cells in fast power banks varies. Some low-quality cells have poor thermal stability at high power levels, making them prone to bulging, explosions, and other problems. Some suppliers, in order to reduce costs, even purchase low-quality cells, which further exacerbates safety risks. Utility Model Content

[0007] The main objective of this invention is to provide a foldable, multi-interface portable power bank that can effectively solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A foldable multi-interface portable power bank includes a power bank body, an indicator light, and two charging interfaces, wherein the indicator light and two charging interfaces are mounted on the power bank body;

[0010] The power bank body has a storage notch on its side wall, and a card interface is provided on the inner wall of the storage notch. A storage-type embedded shell is installed in the storage notch and the card interface, and a charging connector adapted to the card interface is provided on the inner wall of the storage-type embedded shell. The charging connector is adapted to the charging interface.

[0011] The inner wall of the retractable embedded shell is provided with a storage compartment. The storage compartment is connected to a first three-in-one connector and a second three-in-one connector through a first three-in-one wire and a second three-in-one wire, respectively, so as to expand the number of connectors.

[0012] The side wall of the retractable embedded shell has multiple slots, and each slot has a folded metal plate installed inside. By moving the folded metal plate to make it protrude, a gap is formed between the power bank body and the placement surface, which is used to accelerate airflow and improve heat dissipation efficiency.

[0013] In an optional embodiment of this utility model, the two charging ports are symmetrically distributed on the top of the power bank body, and the indicator light is located between the two charging ports. The power bank body and the storage-type embedded shell together form a cuboid object with an arc-shaped edge design.

[0014] In an optional embodiment of this utility model, the storage notch and the card interface are connected, and the inner wall of the card interface is provided with elastic metal. The elastic metal is inserted into the charging connector to realize the connection between the storage-type embedded shell and the power bank body. The storage-type embedded shell and the charging connector are heat-fused and fixed. A printed circuit board is installed inside the storage-type embedded shell.

[0015] In an optional embodiment of this utility model, the first three-in-one connector is connected to the first three-in-one wiring, and the first three-in-one wiring is connected to the printed circuit board of the storage-type embedded shell; the second three-in-one connector is connected to the second three-in-one wiring, and the second three-in-one wiring is connected to the printed circuit board of the storage-type embedded shell.

[0016] In an optional embodiment of this utility model, the first three-in-one connector and the second three-in-one connector are Lightning, Micro USB, and Type-C, respectively, and the first three-in-one connector and the second three-in-one connector are fixed by moving a folding metal piece.

[0017] In an optional embodiment of this utility model, the foldable metal sheet is made of foldable metal material and is hot-melted and fixed to the insertion port of the storage-type embedded shell. After the foldable metal sheet is bent, it lifts up the storage-type embedded shell, thereby lifting up the power bank body.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The retractable connector expansion mechanism effectively expands the number of connectors by retracting the first three-in-one cable, the second three-in-one cable, and the first three-in-one connector and the second three-in-one connector connected to them within the housing. This design meets the needs of different users for multiple interfaces, improving the practicality and compatibility of the power bank.

[0020] The foldable metal plate design not only enhances the power bank's heat dissipation performance but also improves its overall stability and durability. When the foldable metal plate is protruded, it creates a gap between the power bank body and the placement surface, accelerating airflow and effectively improving heat dissipation efficiency. This ensures the power bank maintains good performance during prolonged use, preventing performance degradation or damage due to overheating.

[0021] The combination of a retractable connector extension mechanism and a foldable metal plate further enhances the portability and ease of use of the power bank. The retractable insert can be cleverly installed within the storage notch and card slot of the power bank's main body, saving space and making it convenient for users to carry and store. Meanwhile, the foldable design of the metal plate allows users to easily manipulate it as needed, making operation simple and quick. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figure 1 - Figure 6 As shown, a foldable multi-interface portable power bank consists of a power bank body 1, an indicator light 2, and two charging ports 3. The indicator light 2 and the two charging ports 3 are cleverly installed on the surface of the power bank body 1. A storage notch 4 is specially designed on the side wall of the power bank body 1. This notch not only facilitates storage and carrying for users but also has a practical function. On the inner wall of the storage notch 4, a card slot 5 is specially provided for cooperation with the storage-type embedded shell 6.

[0031] The retractable housing 6 is cleverly installed within the storage notch 4 and card slot 5, and its inner wall has a charging connector 7 adapted to the card slot 5. This charging connector 7 is perfectly compatible with the charging interface 3, ensuring the power bank's efficient charging performance. In addition, the inner wall of the retractable housing 6 also has a storage compartment 8. Inside the storage compartment 8, a first three-in-one connector 10 and a second three-in-one connector 12 are connected via a first three-in-one wire 9 and a second three-in-one wire 11, respectively, thereby expanding the number of connectors to meet the needs of different users.

[0032] To further enhance the practicality of the power bank, multiple slots 13 are provided on the side wall of the retractable housing 6. Each slot 13 contains a foldable metal plate 14, which can be protruded by the user, creating a gap between the power bank body 1 and the placement surface. This design helps accelerate airflow, effectively improving heat dissipation efficiency and ensuring the power bank maintains good performance during prolonged use.

[0033] Remove the storage-type embedded shell 6 and insert the charging connector 7 into the charging interface 3 to expand the number and type of connectors.

[0034] Two charging ports 3 are symmetrically distributed on the top of the power bank body 1, while the indicator light 2 is located between the two charging ports 3, allowing users to easily check the charging status. The power bank body 1 and the retractable housing 6 together form a cuboid shape with rounded edges, which is not only aesthetically pleasing but also increases grip comfort. The storage notch 4 and the card slot 5 are connected. The inner wall of the card slot 5 has a flexible metal element. When the flexible metal element is inserted into the charging connector 7, it securely connects the retractable housing 6 to the power bank body 1. To further enhance the stability of the connection, the retractable housing 6 and the charging connector 7 are fixed by heat fusion, ensuring the overall structural stability. In addition, a printed circuit board is installed inside the retractable housing 6 to support various electronic functions.

[0035] The first three-in-one connector 10 and the second three-in-one connector 12 are respectively connected to the first three-in-one cable 9 and the second three-in-one cable 11, and these two cables are in turn connected to the printed circuit board of the retractable embedded shell 6. The first three-in-one connector 10 and the second three-in-one connector 12 support multiple interfaces such as Lightning, Micro USB, and Type-C, allowing users to choose the appropriate interface for charging their devices. To ensure the stability and durability of the interfaces, the first three-in-one connector 10 and the second three-in-one connector 12 are secured by a sliding folding metal tab 14.

[0036] The foldable metal sheet 14 is made of foldable metal material and is heat-fused to the slot 13 of the storage-type embedded shell 6. When the foldable metal sheet 14 is bent, it can lift the storage-type embedded shell 6, and thus lift the entire power bank body 1, thereby creating a gap between the power bank body 1 and the placement surface, effectively improving heat dissipation efficiency. This design not only improves the heat dissipation performance of the power bank, but also enhances its overall stability and durability.

[0037] First, remove the retractable housing 6 from the storage notch 4. Insert the charging connector 7 inside the retractable housing 6 into the charging port 3 of the power bank body 1, ensuring a secure connection. Connect the first three-in-one connector 10 and the second three-in-one connector 12 via the first three-in-one cable 9 and the second three-in-one cable 11 to expand the number and type of connectors. Select the corresponding three-in-one connector to connect according to the type of device to be charged (such as Lightning, Micro USB, Type-C, etc.). During charging, check the indicator light 2 on the surface of the power bank body 1 to understand the charging status.

[0038] For extended use of the power bank, the folding metal tab 14 on the retractable case 6 can be moved to protrude, creating a gap between the power bank body 1 and the placement surface, thus improving heat dissipation. Connect the device to the extended three-in-one connector or the charging port 3 on the power bank body to begin charging. After use, unplug the charging connector 7 from the charging port 3 and place the retractable case 6 back into the storage notch 4 on the power bank body 1 for convenient next use. This foldable multi-port portable power bank can be used efficiently and safely.
