[0027] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figure 1-3 The detailed description of the embodiments will clearly demonstrate this. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0028] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0029] Example 1: A magnetic attraction device for adaptive cascade charging, comprising:

[0030] Battery Body 1 and Magnetic Cascading Terminal 11: This utility model includes multiple battery bodies 1, each battery body 1 having a magnetic cascading terminal 11 on at least one side. The magnetic cascading terminal 11 includes a magnet N pole 101, a magnet S pole 102, and multiple electrical pins 103. The electrical pins 103 include a contact detection terminal, a communication pin, a positive terminal pin, and a GND pin. During battery cascading, the magnetic cascading terminal 11 of the battery body 1 is guided and magnetically attracted to the magnet S pole 102 of the adjacent battery's magnetic cascading terminal 11 via the magnet N pole 101, and the magnet S pole 102 is guided and magnetically attracted to the magnet N pole 101 of the adjacent battery's magnetic cascading terminal 11, thus easily achieving the cascading of multiple batteries. This magnetic connection method not only simplifies the cascading operation but also ensures the stability of the connection.

[0031] The contact detection terminal is used to detect the contact signal between the batteries on both sides when they are cascaded. When a contact signal is detected, the control unit controls the corresponding MOSFET to turn on, so that the cascaded batteries are electrically connected, ensuring smooth power transmission between the batteries.

[0032] Communication pins play a crucial role in battery cascading, enabling communication with the batteries on either side to obtain information such as the number of cascaded batteries and the power rating of the charger plugged into the Type-C port. This information allows the entire system to adaptively adjust its charging strategy, improving charging efficiency and safety.

[0033] Type C Female Connector 2: Located on top of the battery body 1, Type C Female Connector 2 has multiple functions. Firstly, it enables the charging and discharging of the battery body 1. When the Type C terminal of the battery is plugged into a charger, charging can begin; when plugged into a device, it provides power. Secondly, Type C Female Connector 2 can also be used for cascading charging of multiple batteries, further expanding the battery's application scenarios and flexibility. While the positive and negative terminals are only used for charging and discharging the battery body 1, Type C Female Connector 2, in addition to its charging and discharging function, also supports cascading charging of multiple batteries, clearly defining its roles and improving the functionality and reliability of the device.

[0034] Button 3 and Capacitor Indicator Light 31: Button 3 is located on the top of the battery body 1, and it integrates a four-segment circular multi-color capacitor indicator light 31. The capacitor indicator light 31 displays different colors via button 3, which can be used to distinguish batteries from different users or batteries corresponding to different cameras. This design greatly facilitates users in quickly identifying and using the battery they need in scenarios where multiple batteries are available.

[0035] Other components: The bottom of the battery body 1 is provided with a battery negative terminal 4, a battery communication terminal 5, and a battery positive terminal 6, which are used to realize the electrical connection between the battery and external devices.

[0036] The battery body 1 internally houses an MCU, a protocol chip, and a BUCK-BOOST circuit. When the battery's Type-C terminal is plugged into the charger, the MCU controls the MOSFET to turn off and the ideal diode to turn on. The protocol chip controls the BUCK-BOOST circuit to output the corresponding charging voltage according to the battery's voltage level, ensuring a stable and efficient charging process. When the battery's Type-C terminal is plugged into a device, the MCU controls the MOSFET to turn on, and the protocol chip controls the BUCK-BOOST circuit to discharge the individual battery cells plugged into the device, meeting the device's power requirements.

[0037] The top of the battery body 1 also features a 1 / 4" threaded hole, which serves a dual purpose. It can be used to install screws that secure the upper casing, ensuring the stability of the battery structure; it can also be used to secure lightweight devices, increasing the battery's versatility and application scenarios.

[0038] When using:

[0039] 1. Battery Cascading Operation: When multiple battery bodies 1 are brought close together, the N pole 101 of the magnet will automatically guide and magnetically attract the S pole 102 of the adjacent battery, and vice versa, completing the physical connection. At this time, the contact detection terminal detects a contact signal, and the control unit controls the corresponding MOSFET to turn on, realizing the electrical connection. Simultaneously, the communication pins begin communicating with the cascaded batteries on the left and right sides to obtain information such as the number of cascaded batteries and the charger power.

[0040] 2. Charging process: When the battery's Type C terminal is plugged into the charger, the MCU controls the MOSFET to turn off and the ideal diode to turn on. The protocol chip, based on the battery voltage level, controls the BUCK-BOOST circuit to output the corresponding charging voltage to charge the battery.

[0041] 3. Discharge process: When the Type C terminal of the battery is inserted into the device, the MCU controls the MOS transistor to turn on, and the protocol chip controls the BUCK-BOOST circuit to discharge the individual battery and supply power to the device.

[0042] 4. Battery identification and device fixation: Users can use button 3 to adjust the indicator light 31 to display different colors, thus distinguishing their own batteries. When it is necessary to fix a lightweight device, the 1 / 4 threaded hole on the top of the battery body 1 can be used for fixation.

[0043] Through the above embodiments, the adaptive cascade charging magnetic device of this utility model can efficiently and conveniently realize the functions of battery cascading, charging and discharging, and device fixation, providing users with a better user experience.

[0044] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
