Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging equipment, and in particular to a modular power bank. Background Technology
[0002] In the field of portable charging device manufacturing, existing power banks typically consist of a shell, an internal battery pack (such as lithium-ion cells), a PCB board, and various input / output interfaces (such as USB-A, Type-C, etc.). Their internal structure design must be strictly adapted to the size and shape of specific batteries and the physical specifications of the interfaces.
[0003] The current product development model adopts a targeted R&D strategy. For each battery type and interface combination scheme, the mechanical structure such as battery compartment layout, circuit board fixing position and interface mounting slot needs to be designed separately. This results in the internal structural topology being highly bound to specific components. When market demand changes to other interfaces or differentiated battery specifications (such as cells with different capacities), the original mechanical structure cannot be directly adapted due to a lack of compatibility and scalability. The entire internal architecture must be redesigned and verified. This structural rigidity problem forces companies to invest repetitive R&D resources in each new product, extending the development cycle. Utility Model Content
[0004] The purpose of this utility model is to provide a modular power bank with a modular battery compartment design, which facilitates the replacement of panels with different interfaces and battery cells of different specifications, thereby reducing design costs and shortening the development cycle.
[0005] The technical solution adopted by the modular power bank disclosed in this utility model is: The device includes a bottom shell, a front panel, and a battery pack. The bottom shell has a first slot for mounting the front panel, an opening on its outer side, and a limiting groove for mounting the battery pack. The front panel has a first PCB board with multiple discharge and charging ports, all electrically connected to the first PCB board. The front panel is inserted into the first slot. Near the opening, a second PCB board is electrically connected to the battery pack. The battery pack is inserted into the limiting groove. The second PCB board is electrically connected to the first PCB board. A cover plate is provided on the bottom shell, which contacts the front panel and the battery pack, confining them within the bottom shell.
[0006] As a preferred embodiment, a receiving cavity is formed between the battery pack and the panel, the first PCB board is located in the receiving cavity, and both the first PCB board and the second PCB board are electrically connected to ports, with wires electrically connected between the two ports.
[0007] As a preferred embodiment, the cover plate has a second slot, and the panel is inserted into the second slot.
[0008] As a preferred embodiment, the bottom shell has multiple connecting posts extending inside, the cover plate has multiple mounting holes, the mounting holes have fasteners installed inside, and the fasteners pass through the mounting holes and are fixedly connected to the connecting posts.
[0009] As a preferred embodiment, both sides of the bottom shell have outward protrusions, the connecting post is located inside the protrusions, both sides of the cover plate have connecting portions, and the mounting holes are located on the connecting portions.
[0010] The beneficial effects of the modular power bank disclosed in this utility model are: When market demand changes and other interface types need to be replaced, only the same size panel needs to be replaced, and the required discharge and charging interfaces are configured on the panel. The panel is then installed in the first slot, and the first PCB board and the second PCB board are electrically connected. When market demand changes and requires the use of other specifications of battery cells, it is only necessary to combine the required specifications of battery cells into a battery pack with the same size as the original battery pack, install the battery pack in the limiting groove, and electrically connect the second PCB board to the first PCB board. As a result, when developing new products, companies only need to replace the panel, battery pack, and the corresponding first and second PCB boards, which can reduce the design cost of the bottom shell and cover structure and shorten the product development cycle.

[0017] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Example 1, please refer to Figures 1-3 and Figure 5 .
[0018] The present invention discloses a modular power bank, including a bottom shell 1, a panel 2, a battery pack 3, and a cover plate 4; The top of the bottom shell 1 has an installation opening, through which the panel 2 and the battery pack 3 are inserted into the interior of the bottom shell 1. The outer side of the bottom shell 1 has an opening, and the interior of the bottom shell 1 has a first slot 11 for installing the panel 2. The first slot 11 is close to the opening. In this embodiment, the cross-section of the first slot 11 is preferably U-shaped, so that when the panel 2 is inserted into the first slot 11, the first slot 11 limits three of the sides of the panel 2, thereby improving the firmness of the first slot 11 in constraining the panel 2 and making it easier for the panel 2 to be inserted into the first slot 11 during installation.
[0019] Panel 2 is provided with multiple discharge ports and charging ports. In this embodiment, it is preferred that the external electronic device is electrically connected to the discharge port using a data cable, and the discharge port conducts current to the external electronic device for charging through the data cable. Furthermore, a first PCB board is provided on the panel 2, and the first PCB board 21 is fixedly connected to the panel 2. The discharge interface and the charging interface are both electrically connected to the first PCB board 21.
[0020] Three of the edges of panel 2 are inserted into the first slot 11. Panel 2 is close to the opening, and the discharge interface and charging interface face the outside of the bottom shell 1 through the opening.
[0021] The bottom shell 1 has a limiting groove 12 for installing the battery pack 3 inside, and the first slot 11 and the limiting groove 12 are arranged at intervals. Furthermore, a second PCB board is electrically connected to the battery pack 3, and the second PCB board 31 is fixedly connected to the battery pack 3 and electrically connected to the battery pack 3. Furthermore, the limiting groove 12 is filled with glue, and the battery pack 3 is inserted into the limiting groove 12. The glue adheres the battery pack 3 to the limiting groove 12, improving the firmness of the battery pack 3 installed in the limiting groove 12. A receiving cavity is formed between the battery pack 3 and the panel 2, and the first PCB board 21 is located in the receiving cavity. The second PCB board 31 can be selectively placed in the receiving cavity or in the limiting groove 12. Furthermore, both the first PCB board 21 and the second PCB board 31 are electrically connected to ports 211, and wires are electrically connected between the two ports 211; terminals are electrically connected to both ends of the wires, and the terminals are detachably connected to the ports 211 and conduct current. The external power cord is electrically connected to the charging interface. The charging interface transmits current to the second PCB board 31 through the first PCB board 21 and wires, and charges the battery pack through the second PCB board 31. External electronic devices are electrically connected to the discharge interface via a data cable. The battery pack transmits current to the first PCB board 21 via the second PCB board 31 and wires. The first PCB board 21 charges the external electronic devices via the discharge interface.
[0022] Multiple connecting posts 131 extend from the inner wall of the bottom shell 1, and the multiple connecting posts 131 are respectively close to both sides of the inner wall of the bottom shell 1; multiple mounting holes 421 are passed through the cover plate 4, and the multiple mounting holes 421 are respectively close to both sides of the cover plate 4, and a fixing member is provided in the mounting hole 421; the cover plate 4 is placed on the mounting opening of the bottom shell 1, and the cover plate 4 touches the panel 2 and the battery pack 3, constraining the two within the bottom shell 1; the fixing member passes through the mounting hole 421 and is fixedly connected to the connecting posts 131, thus fixing the cover plate 4 to the bottom shell 1; Furthermore, a second slot 41 is provided on the cover plate 4, and the other side of the panel 2 is inserted into the second slot 41, which improves the firmness of the panel 2 installed between the bottom shell 1 and the cover plate 4.
[0023] When market demands change and a different interface type is required: A panel 2 with the same outline size is selected, and a discharge interface and a charging interface that meet the new requirements are arranged on it; then the new panel 2 is installed in the first slot 11, and the second PCB board 31 is connected to the first PCB board 21 through wires, so that the interface of this power bank meets the new requirements. When market demand changes and other specifications of battery cells need to be used: The battery cells that meet the new requirements are assembled into a new battery pack 3, whose external dimensions are consistent with the original battery pack 3; then the new battery pack 3 is installed in the limiting groove 12, and the first PCB board 21 and the second PCB board 31 are connected by wires, so that the battery pack 3 of this power bank meets the new requirements. Therefore, when developing new products, companies only need to replace panel 2, battery pack 3, and the corresponding first PCB board and second PCB board, which can reduce the design cost of the bottom shell 1 and cover plate 4 structure and shorten the product development cycle.
[0024] Example 2, please refer to Figures 4-6 .
[0025] Based on the original embodiment 1, both sides of the bottom shell 1 have protrusions 13 that bulge outwards, and the two sides of the inner wall of the bottom shell 1 form additional spaces, with multiple connecting columns 131 located in the two protrusions 13 respectively. Both sides of the cover plate 4 have connecting parts 42, and multiple mounting holes 421 are located on the two connecting parts 42 respectively; when the cover plate 4 is placed on the bottom shell 1, the mounting holes 421 correspond to the connecting posts 131. The protrusion 13 can increase the internal space of the bottom shell 1 and prevent the connecting post 131 from encroaching on the installation space of the battery pack 3.
[0026] This utility model provides a modular power bank. When market demand changes and other interface types need to be replaced, only the panel of the same size needs to be replaced, and the required discharge and charging interfaces are configured on the panel. The panel is installed in the first slot, and the first PCB board and the second PCB board are electrically connected. When market demand changes and requires the use of other specifications of battery cells, it is only necessary to combine the required specifications of battery cells into a battery pack with the same size as the original battery pack, install the battery pack in the limiting groove, and electrically connect the second PCB board to the first PCB board. As a result, when developing new products, companies only need to replace the panel, battery pack, and the corresponding first and second PCB boards, which can reduce the design cost of the bottom shell and cover structure and shorten the product development cycle.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
