Description

Technical Field

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

[0002] A power bank is a portable charger that can be carried by the user and stores its own electrical energy. It is mainly used to charge consumer electronic products such as handheld mobile devices (e.g., cordless phones, laptops), especially in situations where there is no external power supply. Its main components include: a battery for storing electrical energy, a circuit for stabilizing the output voltage (DC-DC converter), and most power banks come with a charger for charging the built-in battery. Currently, power bank cables are usually of the retractable or exposed type, and the cable connectors are prone to detaching from the power bank, causing the cables to become tangled or damaged.

[0003] Power bank devices typically come with a single-wire single-end or single-wire multi-end, but can only charge one device at a time. Furthermore, the stability of the wire connector when placed and fixed to the power bank is low, making it difficult to limit and fix the connector. The connector is prone to detaching from the power bank, causing the wire to become tangled or the connector to be squeezed and damaged. Therefore, those skilled in the art have provided a power bank to solve the problems mentioned in the background art. Utility Model Content

A motherboard is installed inside the housing and on the other side of the stretching coils. Two interfaces are installed on one side of the motherboard. Two sets of limiting members are installed inside the placement box.

[0007] Preferably, the limiting component includes two placement compartments opened at the top of the placement box, and limiting strips are connected to the two sides inside the placement compartments respectively. The limiting strips have a semi-circular cross-section.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 In this embodiment of the utility model, a power bank includes a power bank housing 1, a base plate 2 snapped onto the bottom of the housing 1, two battery blocks 3 installed inside the housing 1, a placement box 4 installed on the top of the housing 1, two sets of tension coils 5 installed inside the housing 1, charging connectors 6 connected to the ends of the tension coils 5, a main board 7 installed inside the housing 1 and on the other side of the tension coils 5, two interfaces 8 installed on one side of the main board 7, and two sets of limiting members installed inside the placement box 4.

[0025] In use, the two interfaces 8 are mainly USB-C and USB-USB ports, which are used to charge the power bank. The charging connector 6 can drive the tension coil 5 to wind and stretch. The placement box 4 can place the charging connector 6. The limiting component can limit and fix the charging connector 6 to prevent the charging connector 6 from coming off and causing the wires to become tangled or squeezed and damaged. The charging connectors 6 at the ends of the two tension coils 5 can be used to charge the two devices simultaneously.

[0026] In one embodiment, the limiting component includes two placement compartments 9 opened on the top of the placement box 4, with limiting strips 10 connected to the two sides inside the placement compartments 9 respectively. An elastic strip 14 is embedded inside the limiting strip 10, and an anti-slip pad 13 is laid at the bottom of the placement compartments 9. The limiting strip 10 has a semi-circular cross section.

[0027] Among them, the two placement bins 9 on the top of the placement box 4 can place the two charging connectors 6. The anti-slip pads 13 laid at the bottom of the placement bins 9 can provide anti-slip protection for the charging connectors 6 to prevent the charging connectors 6 from sliding. The limiting strips 10 are made of rubber, and the two limiting strips 10 can undergo elastic deformation. The elastic strips 14 can support the limiting strips 10. The two limiting strips 10 can limit and fix the charging connectors 6 to prevent the charging connectors 6 from shifting or detaching.

[0028] Furthermore, protective pads 11 are embedded on the inner side of the housing 1 and on the other side of the bottom plate 2. Insulating gaskets 12 are laid between the two battery blocks 3. A heat dissipation pad 15 is laid on one side of the bottom plate 2 and at the bottom of the battery blocks 3.

[0029] In one embodiment, specifically, the cross-section of the protective pad 11 is "day" shaped. The protective pad 11 on one side of the bottom plate 2 and the protective pad 11 on one side of the housing 1 are respectively located on both sides of the battery blocks 3, enabling the housing 1 and the bottom plate 2 to clamp and fix the two battery blocks 3 by means of the protective pads 11 to prevent the battery blocks 3 from shaking or shifting. The insulating gaskets 12 can provide insulating separation protection for the two battery blocks 3 to avoid damage to the device caused by electric leakage of the battery blocks 3. The heat dissipation pad 15 can conduct heat and dissipate heat from the bottom of the two battery blocks 3, extending the service life of the battery blocks 3.

[0030] The working principle of the present utility model:

[0031] First, the charging connectors 6 pull the stretching coil 5 to extend. The two charging connectors 6 can simultaneously charge two devices. After charging is completed, the stretching coil 5带动 the charging connectors 6 to contract. Then, the charging connectors 6 are placed in the placement bins 9 on the top of the placement box 4. Then, the anti-slip pads 13 wrap and protect the charging connectors 6. At the same time, the two limiting strips 10 undergo elastic deformation, and then the elastic strips 14 support the limiting strips 10. At this time, the two limiting strips 10 limit and fix the charging connectors 6.

[0032] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
