[0032] Control module 1 is located on the main body 10;

[0033] Battery charging module 2 is electrically connected to control module 1 and is used to charge battery 20.

[0034] The battery voltage detection module 3 is electrically connected to the control module 1, and is used to detect the voltage of the battery 20.

[0035] Display module 4 is electrically connected to control module 1 and is used to display the power status of battery 20.

[0036] Through the above structure, by setting multiple battery receiving slots 11 within the main body 10, the function of simultaneously charging multiple batteries 20 is realized, significantly improving charging efficiency and meeting users' needs for charging batteries 20 from multiple devices.

After connecting to the power supply, the battery charger obtains power through the power input module 6 to power the other modules of the charger and begin charging.

[0038] In this embodiment, a boost module 8 is also included. When the battery is placed in the battery housing 11, the boost module 8 is electrically connected to the battery, the control module 1, the battery voltage detection module 3, and the display module 4. The boost module 8 is used to increase the input voltage of the battery 20 to power the control module 1, the battery voltage detection module 3, and the display module 4. With the above structure, when the battery is placed in the battery housing 11 and there is no external input power, the battery's input voltage is increased to 3.3V through the boost module to reach the voltage required by other modules of the battery charger, ensuring that real-time detection and display of the battery voltage can be achieved without an external charging power supply.

After the cover 13 is closed, the cover closure detection module 5 will detect whether the cover 13 is completely closed with the compartment 12 and transmit the detection result to the control module 1. If the closure is normal, the control module 1 will start the battery charging module 2 to charge the battery 20. At the same time, the battery voltage detection module 3 will monitor the voltage status of the battery 20 in real time and display the real-time battery level information of the battery 20 through the display module 4, so that the user can intuitively understand the charging status of the battery 20.

The temperature detection module 7 can monitor the temperature of the batteries 20 to ensure that the batteries 20 do not overheat during charging, thus effectively preventing safety accidents caused by overheating. This allows users to intuitively view the temperature status of each battery 20, improving safety and convenience of use.

[0043] In this embodiment, the outer side wall of the main body 10 is provided with a corrugated protrusion 101 circumferentially from top to bottom; through the above structure, the outer side wall of the battery charger main body 10 is provided with a corrugated protrusion 101 structure circumferentially from top to bottom.

[0044] In this embodiment, the cover 13 is rotatably fitted onto the compartment 12 via a pivot. A magnetic element 121 is located at the end of the compartment 12 furthest from the pivot, and a magnetic engaging element 131 is located at the end of the cover 13 corresponding to the magnetic element 121. When the cover 13 is fitted onto the compartment 12, the magnetic element 121 and the magnetic engaging element 131 are magnetically connected. With this structure, the cover 13 of the battery charger is rotatably fitted onto the compartment 12 via the pivot, facilitating opening and closing for the user. When the user closes the cover 13 onto the compartment 12, the magnetic element 121 and the magnetic engaging element 131 automatically attract and connect through magnetic force, ensuring that the cover 13 is securely closed onto the compartment 12. This design not only simplifies the closing operation of the cover 13 but also provides a more stable closing state, preventing the charger's performance or safety from being affected by a loose cover 13.

[0045] In this embodiment, the housing 12 includes an outer shell 122 and a charging base 123 disposed within the outer shell 122. A plurality of battery receiving slots 11 are arrayed on the charging base 123. Multiple slots 1231 are provided around the periphery of the charging base 123. Multiple latches 1221 are provided on the inner wall of the outer shell 122 corresponding to the slots 1231. The charging base 123 and the outer shell 122 are connected via the latches 1221. This structure, using the latches 1221, makes the connection between the charging base 123 and the outer shell 122 simpler and more secure, avoiding the complexity of traditional screws or other fixing methods.

[0046] In this embodiment, the positive electrode 21 is disposed at the bottom of the charging base 123, the negative electrode 22 is disposed inside the cover 13 of the battery receiving slot 11, and the input port 61 is electrically connected to the positive electrode and the negative electrode to charge the battery 20 in the battery receiving slot 11.

The digital display module 42 includes several digital displays 421. The battery receiving slots 11 are arrayed on the compartment 12, and the cover 13 is provided with digital displays 421 at positions corresponding to the battery receiving slots 11. When the battery voltage detection module 3 detects that the battery 20 is in a first voltage range, the digital displays 421 display the first numerical range. When the battery voltage detection module 3 detects that the battery 20 is in a second voltage range, the digital displays 421 display the second numerical range. When the battery voltage detection module 3 detects that the battery 20 is in a third voltage range, the digital displays 421 display the third numerical range.

[0049] In this embodiment, the first voltage range is 0V-1.3V, and the first numerical range is 0%-33%; the second voltage range is 1.31V-1.45V, and the second numerical range is 34%-66%; the third voltage range is 1.46V-1.5V, and the third numerical range is 67%-100%. By setting the digital display module 42 and the specific voltage range corresponding to the power display, the user can clearly and intuitively understand the power status of each battery 20. The percentage display on the digital display screen 421 can accurately convey the remaining power of the battery 20, avoiding the ambiguity of traditional chargers that only use indicator lights 411 or simple icons to indicate the power of the battery 20, thereby improving the user experience and ease of use.
