[0023] To better understand the technical solution of this utility model, the embodiments provided by this utility model are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-3 As shown, this embodiment provides a battery charging box, including: a box body 1 and a cover 2, the cover 2 being closable and covering the box body 1; the box body 1 is provided with a plurality of charging slots 3, the charging slots 3 being used to accommodate rechargeable batteries 4; each charging slot 3 has a charging contact at its bottom, and the cover 2 is also provided with a charging contact at a position corresponding to the charging slot 3; it also includes a plurality of intermediate conversion parts 5, the intermediate conversion parts 5 being detachably disposed in the charging slots 3, and the outer wall matching the shape of the charging slots 3; one end of the intermediate conversion part 5 is open, and the other end is provided with a small hole or is set as an open end.

[0025] In this embodiment, the cover 2 is rotatably connected to the box 1 and can be opened and closed. The charging slot 3 inside the box 1 is used to accommodate the rechargeable battery 4. Charging is achieved by the charging contacts at the top and bottom contacting both ends of the battery 4. The rechargeable battery 4 in this embodiment has various models, such as AA and AAA. A special feature is the inclusion of several intermediate conversion components 5. These intermediate conversion components 5 have the same shape as the charging slot 3 but are smaller in scale, used to accommodate smaller batteries 4. This allows for the conversion of the rechargeable battery 4 model and, depending on the number of intermediate conversion components 5, the simultaneous charging of different battery models 4. The size of the intermediate conversion components 5 in this embodiment can be adjusted according to the model of the battery 4 that needs to be charged. To ensure charging efficiency, both ends of the intermediate conversion components 5 are not closed, allowing the battery 4 placed in the intermediate conversion components 5 to contact the charging contacts at both ends for charging. In this embodiment, the upper end of the intermediate conversion component 5 is open, and the bottom end has a small hole for charging contacts. In other embodiments, both ends can be open or in other unclosed states.

[0026] Furthermore, the diameter of the intermediate conversion component 5 is smaller than the diameter of the charging slot 3. The intermediate conversion component 5 is provided to accommodate batteries 4 of different models; therefore, the diameter of the intermediate conversion component 5 is smaller than the diameter of the outer charging slot 3 to accommodate batteries 4 with smaller diameters.

[0027] Furthermore, the number of intermediate conversion components 5 is no greater than the number of charging slots 3. The number of intermediate conversion components 5 can be equal to or less than the number of charging slots 3, enabling complete replacement with charging of other types of batteries 4, or partial replacement.

[0028] Based on the above embodiment, the top edges of several intermediate conversion parts 5 are connected into a whole by connecting parts 6. The intermediate conversion part 5 can be a single unit, but for convenience, the tops of each intermediate conversion part 5 can be connected to form a whole.

[0029] In this embodiment, a first mounting component 7 and a second mounting component 8 are also included. The first mounting component 7 is disposed inside the cover 2, and the second mounting component 8 is disposed inside the box 1. A first mainboard is disposed inside the first mounting component 7, and charging contacts are provided on the first mainboard. The charging slot 3 is disposed inside the second mounting component 8, which also contains a second mainboard, and charging contacts are provided on the second mainboard. The first mounting component 7 and the second mounting component 8 are used to assist in the installation of various components within the cover 2 and the box 1, respectively.

[0030] Furthermore, to connect the first and second motherboards, the second mounting component 8 is provided with a through-hole connecting groove 9, within which a metal connector 10 is installed. The first mounting component 7 has a connecting contact point 11, one end of which is located on the first motherboard. One end of the metal connector 10 is fixed to the second motherboard, while the other end detachably abuts against the connecting contact point 11. The metal connector 10 connects the first and second motherboards through-hole, and the metal connector 10 abuts against the connecting contact point 11. When the cover 2 is opened, the connecting contact point 11 separates from the metal connector 10, ending charging. When the cover 2 is closed, the connecting contact point 11 abuts against the metal connector 10, and charging continues. A charging port is provided on the outside of the housing 1 for connecting an external power source. The charging port connects to the first and second motherboards to enable charging.

[0031] The above provides a detailed description of a battery charging box provided by the embodiments of this utility model. For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
