Description

Technical Field

[0001] This utility model belongs to the field of charging equipment technology, and in particular relates to a power bank with a switchable charging interface. Background Technology

[0002] With the widespread use of smartphones, tablets, and other mobile devices, users' demand for battery replenishment devices is increasing daily. Power banks, as portable energy storage products, have become essential tools for daily travel and office use. Currently, the core function of power bank products on the market revolves around "providing power replenishment for mobile devices with different interface types."

[0003] Current power banks generally come in three types: those with a fixed single interface, those with fixed multiple interfaces, and those with a fixed data cable. For a single fixed interface, it is only configured with a single type of interface, and you need to carry an additional data cable with the corresponding interface, which increases the burden of carrying it when traveling and goes against the core design intention of portable energy storage of power banks. For fixed multi-port designs, the multi-port design not only takes up more space in the casing, increasing the size of the power bank, but also exposes the ports to the outside for a long time, making them susceptible to dust or water droplets, which can lead to oxidation of the port contacts and short circuits in the internal power PCBA. For fixed data cables, although it is possible to achieve compatibility without additional cables by having 1-2 built-in fixed data cables, this solution has the problems of easy data cable wear and limited usage scenarios. The built-in data cables are prone to core breakage due to repeated bending, which affects normal use.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a power bank with a switchable charging interface to overcome the shortcomings in current practical applications. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model embodiment is to provide a power bank with a switchable charging interface to solve the problems in the background technology mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A power bank with a switchable charging interface includes a power bank body, a power PCBA inside the power bank body, a charging groove on one side of the power bank, symmetrical shaft holes on two side walls of the charging groove, two limiting plates arranged parallel to each other on one side of the shaft holes, both limiting plates being fixed to the side wall of the charging groove, and a limiting slot being formed between the two limiting plates, and further includes: A switching component is disposed inside the charging recess. Both ends of the switching component are rotatably mounted in the shaft hole, and both ends of the switching component cooperate with the limiting slot. The switching component is connected to the power PCBA. A TYPE-C male connector and a Lightning male connector are fixed on one side of the switching component, and the TYPE-C male connector and the Lightning male connector are perpendicular to each other.

[0007] As a further technical solution of this utility model, the switching component includes a switching base, a rotating shaft, a locking plate, and an FPC flexible flat cable. The left and right sides of the switching base are fixed with rotating shafts and locking plates, and two locking plates are provided on the same side of the switching base. The two locking plates on the same side of the switching base are perpendicular to each other, and the two locking plates alternately cooperate with the limiting slots. The switching base is respectively equipped with a TYPE-C male connector and a Lightning male connector. The Lightning male connector is electrically connected to the FPC flexible flat cable and the TYPE-C male connector, respectively. One end of the FPC flexible flat cable extends into the inside of the power bank and is inserted into the ribbon cable interface of the power PCBA.

[0008] As a further technical solution of this utility model, the switching seat is a plastic part, which is connected to the FPC flexible flat cable, TYPE-C male interface and Lightning male interface as a whole by overmolding injection molding, and the rotating shaft and the card plate on the side wall of the switching seat are integrally injection molded with it.

[0009] As a further technical solution of this utility model, the Lightning male connector is provided with a Lightning interface PCB, and solder joints are distributed on both sides of the Lightning interface PCB. The solder joints on both sides of the Lightning interface PCB are respectively soldered to the TYPE-C male connector and the FPC flexible flat cable.

[0010] As a further technical solution of this utility model, the TYPE-C male connector is provided with a TYPE-C interface PCB, and solder joints are distributed on one side of the TYPE-C interface PCB. The solder joints on one side of the TYPE-C interface PCB are soldered together with one side of the Lightning interface PCB.

[0011] As a further technical solution of this utility model, a protective cover for shielding the charging groove is also installed on one side of the main body of the power bank. The protective cover is a silicone dust cover that is interference-fitted with the edge of the charging groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The switching component is connected to the power PCBA. One side of the switching component has a Type-C male connector and a Lightning male connector fixed to it, perpendicular to each other. By rotating the switching component 90 degrees, the positions of the Type-C and Lightning male connectors can be changed, allowing them to alternately rotate to a position perpendicular to the charging recess. This enables quick switching between the two interfaces, replacing the two data cables found on traditional power banks. Users no longer need to carry extra cables; simply rotating the switching component allows for compatibility with both Apple and Android phones, solving the core pain point of carrying multiple cables when traveling with multiple devices. The operation is simple and quick, improving the user experience.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] like Figures 1 to 5 As shown, a power bank with a switchable charging interface provided as an embodiment of this utility model includes a power bank body 1, a power PCBA is provided inside the power bank body 1, a charging groove 2 is provided on one side of the power bank, shaft holes 7 are symmetrically provided on the two side walls of the charging groove 2, and two limiting plates 8 are arranged parallel to one side of the shaft holes 7. The two limiting plates 8 are fixed on the side wall of the charging groove 2, and a limiting slot is formed between the two limiting plates 8. The power bank also includes: A switching component 4 is disposed inside the charging recess 2. Both ends of the switching component 4 are rotatably mounted within the shaft hole 7, and both ends cooperate with the limiting slots. The switching component 4 is connected to the power PCBA. A TYPE-C male connector 5 and a Lightning male connector 6 are fixed to one side of the switching component 4, respectively. The TYPE-C male connector 5 and the Lightning male connector 6 are perpendicular to each other. By rotating the switching component 4 90 degrees, the positions of the TYPE-C male connector 5 and the Lightning male connector 6 can be changed, allowing them to alternately rotate to a position perpendicular to the charging recess 2. This enables quick switching between the two interfaces, replacing the two data cables on a traditional power bank. Users no longer need to carry additional data cables; simply rotating the switching component 4 allows for compatibility with both Apple and Android phones, solving the core pain point of carrying multiple cables when traveling with multiple devices. The operation is simple and quick, improving the user experience.

[0023] like Figures 2 to 5 As shown in the preferred embodiment of this utility model, the switching component 4 includes a switching base 41, a rotating shaft 42, a retaining plate 43, and an FPC flexible flat cable. The rotating shaft 42 and the retaining plate 43 are fixed on both the left and right sides of the switching base 41, and two retaining plates 43 are provided on the same side of the switching base 41. The two retaining plates 43 located on the same side of the switching base 41 are perpendicular to each other, and the two retaining plates 43 alternately cooperate with the limiting slots. A TYPE-C male connector 5 and a Lightning male connector 6 are respectively installed on the switching base 41. The Lightning male connector 6 is electrically connected to the FPC flexible flat cable and the TYPE-C male connector 5 respectively. One end of the FPC flexible flat cable extends into the inside of the power bank and is inserted into the ribbon cable interface of the power supply PCBA.

[0024] The engagement between the pivot 42 and the shaft hole 7 allows the switching base 41 to rotate 90 degrees back and forth within the charging recess 2, thereby changing the positions of the TYPE-C male connector 5 and the Lightning male connector 6. This allows the TYPE-C male connector 5 and the Lightning male connector 6 to rotate alternately to a position perpendicular to the charging recess 2, enabling quick switching between the two interfaces. This replaces the two data cables on a traditional power bank, eliminating the need for users to carry additional data cables. Users can simply rotate the switching component 4 to adapt to both Apple and Android phones, solving the core pain point of having to carry multiple cables when traveling with multiple devices.

[0025] like Figures 2 to 5 As shown, in a preferred embodiment of the present invention, the switching base 41 is preferably a plastic part, which is connected to the FPC flexible flat cable, the TYPE-C male connector 5 and the Lightning male connector 6 as a whole by overmolding injection molding. The rotating shaft 42 and the clamping plate 43 on the side wall of the switching base 41 are integrally injection molded with it.

[0026] like Figures 2 to 5 As shown, in a preferred embodiment of the present invention, the Lightning male connector 6 is provided with a Lightning interface PCB. Solder joints are distributed on both sides of the Lightning interface PCB, and the solder joints on both sides of the Lightning interface PCB are respectively soldered to the TYPE-C male connector 5 and the FPC flexible flat cable.

[0027] like Figures 2 to 5 As shown, in a preferred embodiment of the present invention, the TYPE-C male connector 5 is provided with a TYPE-C interface PCB, and solder joints are distributed on one side of the TYPE-C interface PCB. The solder joints on one side of the TYPE-C interface PCB are soldered together with one side of the Lightning interface PCB.

[0028] like Figure 1 and Figure 2 As shown in the preferred embodiment of this utility model, a protective cover 3 for shielding the charging groove 2 is also installed on one side of the power bank body 1. The protective cover 3 is preferably a silicone dust cover, which is interference-fitted with the edge of the charging groove 2. When the power bank is idle, it can cover the charging groove 2, thereby protecting the TYPE-C male connector 5 and the Lightning male connector 6, preventing dust and other impurities from entering the interface, reducing interface contact failures caused by dust, and thus extending the service life of the TYPE-C male connector 5 and the Lightning male connector 6.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
