The high-speed analog switch is electrically connected to the LDO voltage stabilization circuit and the card reader slot 12. By inserting an SD card or a TF card into the card reader slot 12, the storage of the memory card can be realized. When the control module is connected to an external device, such as a computer or a mobile phone and other terminal devices, through a connection line, the data information stored in the memory card inserted into the card reader slot can be directly read. The integration degree is high, and the photographer does not need to additionally configure a card reader, reducing the number of related accessories that need to be carried when the photographer goes out and reducing the burden.

The power management circuit is connected to an interface circuit 23. By inserting a connection line into the interface circuit 23, the control module is connected and communicated with an external device, so as to meet the data transmission requirements, and further achieve the effect of being compatible with a card reader, and directly read the data information in the memory card in the connected device. In addition, by inserting a connection line into the interface circuit 23, the storage box is connected to an external power supply, and the external power supply can provide electrical energy for the operation of each circuit component in the storage box and charge and store energy for the battery in the storage box.

When the user is shooting outdoors, the spare camera battery is stored and placed in the battery storage compartment 11, so that the electrode plate of the camera battery contacts the contacts 111 in the battery storage compartment 11, thereby realizing the electrical connection between the camera battery and the control module. After the camera battery is placed in the battery storage compartment 11, if the main control MCU circuit determines that the power of the camera battery is insufficient, the output voltage of the energy storage battery is converted into DC4.4V through the boost circuit, and then the electric energy is transmitted to the camera battery to charge the camera battery. Connect an external power supply through the interface circuit 23, and then convert the voltage through the power management circuit to charge the energy storage battery to meet the charging and endurance requirements of the energy storage battery. The main control MCU circuit is connected to a MOS tube switching circuit. The MOS tube switching circuit is electrically connected to the power management circuit and the contacts 111 in the battery storage compartments 11.

Through calculation by the main control MCU circuit, the current power levels of the energy storage battery and the camera battery can be obtained and displayed on the display circuit 21. Users can intuitively obtain the remaining power level of the energy storage battery on the display circuit 21. After placing the camera battery in the corresponding battery storage compartment 11, the real-time power level and charging status of the camera battery can be viewed.

The display circuit 21 and the button module 22 can be set on the cover 3 for easy viewing and operation directly on the cover 3. However, this setting method requires setting connecting wires inside the hinge position between the cover 3 and the box body 1. Under the operation of opening and closing the cover multiple times, there is a situation where the connecting wires are fatigued and damaged, thereby affecting the display or button functions. A fastening mechanism 31 is provided at the joint between the cover 3 and the box body 1. The fastening mechanism 31 adopts one or both of a magnetic attraction structure or a snap structure. The cover 3 is locked on the box body 1 through the fastening mechanism 31 to prevent the cover 3 from accidentally opening during storage, resulting in the internal camera battery falling out of the battery storage compartment 11. In summary, through the setting of a card reader slot connected to the control module in this application, by inserting an SD card or a TF card into the card reader slot 12, the storage of the memory card can be realized; when the control module is connected to an external device, such as a computer or a mobile phone and other terminal devices through a connecting wire, the data information stored in the memory card inserted into the card reader slot can be directly read.

The output and input states of the camera battery are switched through the MOS transistor switching circuit. Thus, when connected to a mobile phone through the interface circuit 23, the energy storage battery is used to supply power to the connected device such as a mobile phone to meet the requirement of charging the mobile phone; when the remaining power of the energy storage battery is low or the electric energy is exhausted, the camera battery is switched to the output state through the MOS transistor switching circuit, so that the camera battery can directly supply power to the mobile phone, enabling the camera battery to act as a mobile power source to achieve reverse power supply. Please refer to FIG. 3. The interface circuit 23 further includes a USB connecting wire 24. The end 241 of the USB connecting wire 24 is a USB A plug or a Type-C plug. The USB connecting wire 24 passes through from one side surface of the outer corner of the box body 1. A storage groove 13 is provided on the other side surface of the outer corner. A limiting block 131 is provided on one side of the storage groove 13 close to the outer corner. A wire passing hole is provided between the limiting block 131 and the bottom surface of the storage groove 13. The USB connecting wire 24 passes through the wire passing hole, and the end 241 of the USB connecting wire 24 is limited by the limiting block 131. When the end 241 of the USB connecting wire 24 is stored in the storage groove 131, the USB connecting wire 24 forms a U-shaped hanging belt at the outer corner of the box body 1, which is convenient for carrying or hanging the storage box by hand. In summary, in this application, the energy storage battery is used to charge the camera battery placed in the battery storage compartment. The detection circuit is adopted to detect the current power levels of the energy storage battery and the camera battery in real time. The main control MCU circuit calculates the detection results, and finally the power status is output on the display circuit. While meeting the function of storing the camera battery, it can also charge the camera battery. This avoids the situation where the photographer needs to frequently replace the spare camera battery due to the inability to timely judge the remaining power during long-term outdoor shooting, improves the replacement efficiency of the camera battery, and provides battery life guarantee for long-term outdoor shooting.
