At this time, the moving block is unlocked and can move freely in the moving groove, thereby driving the connecting plate and the battery protection board to move to the desired position. The sensing module on the battery protection board is used to collect various parameter information of the battery and This information is transmitted to the over-discharge identification module above. The over-discharge identification module uses advanced circuit design and algorithms to accurately analyze and judge the received parameters to determine whether the battery is in an over-discharge state. After adjusting the position of the battery protection board, release the card block, the spring returns to its original state, and pushes the sliding block to move in the opposite direction, so that the card block is re-engaged in the card slot on the surface of one side of the installation box, and the battery protection board is locked in the new position, ensuring that the battery protection board stably monitors and protects the battery status during operation. The heat absorption plate is tightly fixed on the inside of the heat dissipation slot, and the heat generated by the battery protection board during operation is conducted to the heat absorption plate itself, achieving initial heat accumulation and absorption. The heat absorbed by the heat absorption plate is then transferred to the heat absorption plate by the conduction plate. The heat is efficiently transferred to the heat sink. The heat sink has a large surface area and can further disperse the conducted heat. The heat sink is fixed on the upper surface of the heat sink at equal intervals. The heat sink greatly increases the surface area in contact with the air. Air, as a medium for heat transfer, exchanges heat with the heat sink and takes away the heat on the heat sink, thereby achieving a heat dissipation effect. The bumps further increase the surface area of ​​the heat sink. The heat generated by the battery protection board can be quickly dissipated to the surrounding environment, maintaining the overall low-temperature operation state of the battery protection board, ensuring its internal circuit to work stably and reliably, and enabling temperature-sensitive components such as the over-discharge identification module to function accurately. Install the mounting plate along the top of the base. The slot slides forward, and when the mounting plate drives the shield cover to move, the mounting block on one side of the shield cover also moves together. When the mounting block moves to the position corresponding to the positioning column fixedly connected to the base, the positioning column will slide into the positioning slot opened on one side of the mounting block. The shield cover effectively blocks external electromagnetic interference, and the circuit can operate in a relatively stable electromagnetic environment, which improves the accuracy and reliability of over-discharge identification. The adjustment mechanism can flexibly adjust the position as needed, which is convenient for maintenance and component replacement, and fully ensures the stable and efficient operation of the battery protection function. The heat dissipation mechanism ensures that the battery protection board can maintain a good heat dissipation state in different working environments and working conditions, thereby extending its service life and ensuring the safe and stable operation of the battery system.

The sensing module 708 on the battery protection plate 706 is used to collect various parameter information of the battery 5 and transmit this information to the over-discharge identification module 707 above. The over-discharge identification module 707 uses advanced circuit design and algorithms to accurately analyze and judge the received parameters to determine whether the battery 5 is in an over-discharge state. After adjusting the position of the battery protection plate 706, the card block 716 is released, the spring 715 returns to its original state, and pushes the sliding block 714 to move in the opposite direction.The card block 716 is re-engaged in the card slot 717 on the side surface of the installation box 2 to lock the battery protection board 706 in the new position, ensuring that the battery protection board 706 stably monitors and protects the status of the battery 5 during operation.

[0033] Furthermore, the inner dimension of the limiting groove 702 is consistent with the outer dimension of the limiting block 703, and two groups of limiting blocks 703 are symmetrically arranged around the central axis of the moving block 704. Through the setting of the limiting blocks 703, when in use, the two limiting blocks 703 simultaneously limit the moving block 704, making the moving block 704 more stable during the sliding process.

[0034] Furthermore, two groups of connecting plates 705 are symmetrically arranged around the central axis of the battery protection board 706. The sensing module 708 is connected to the over-discharge identification module 707 through the battery protection board 706.

[0037] Furthermore, the heat dissipation mechanism 8 includes a heat dissipation groove 801, a heat absorbing plate 802, a conductive plate 803, a heat dissipation plate 804, a heat dissipation fin 805 and a protrusion 806. The inner surface of the battery protection plate 706 is provided with a heat dissipation groove 801, the inner surface of the heat dissipation groove 801 is fixedly connected to the heat absorbing plate 802, one side surface of the heat absorbing plate 802 is fixedly connected to the heat absorbing plate 802, one side surface of the heat absorbing plate 802 is fixedly connected to the conductive plate 803, the upper surface of the conductive plate 803 is fixedly connected to the heat dissipation plate 804, the upper surface of the heat dissipation plate 804 is fixedly connected to the heat dissipation fin 805, and one side surface of the heat dissipation fin 805 is fixedly connected to the protrusion 806. Through the arrangement of the heat dissipation groove 801, the heat absorbing plate 802, the conductive plate 803, the heat dissipation plate 804, the heat dissipation fin 805 and the protrusion 806, when in use, the heat absorbing plate 802 is tightly fixed to the inner side of the heat dissipation groove 801, and the heat generated by the battery protection plate 706 when working is reduced.

The heat dissipation plate 804 has a large surface area and can further disperse the conducted heat. The heat sink 805 is fixed on the upper surface of the heat sink 804 at equal intervals. The heat sink 805 greatly increases the surface area in contact with the air. As a medium for heat transfer, the air will exchange heat with the heat sink 805 and take away the heat on the heat sink 805, thereby achieving a heat dissipation effect. The bump 806 further increases the surface area of ​​the heat sink 805. The heat generated by the battery protection board 706 can be quickly dissipated to the surrounding environment, maintaining the overall low-temperature operation state of the battery protection board 706, ensuring the stable and reliable operation of its internal circuit, and enabling the over-discharge identification module 707 and other temperature-sensitive components to function accurately.

[0039] Working principle: When installing batteries 5 of different sizes or performing maintenance and inspection on the protection plate, if you need to adjust the position of the battery protection plate 706, press the card block 716. The card block 716 is forced to drive the sliding block 714 to move toward the side of the spring 715, compressing the spring 715. At the same time, the connecting column 713 drives the limiting block 712 to slide in the limiting groove 711, and the card block 716 retracts and disengages from the engaging state with the card slot 717. At this time, the moving block 704 is unlocked and can move freely in the moving groove 701, thereby driving the connecting plate 705 and the battery protection plate 706 to move to the desired position. The sensing module 708 on the battery protection plate 706 is used to collect various parameters of the battery 5. The over-discharge identification module 707 above uses advanced circuit design and algorithm to accurately analyze and judge the received parameters to determine whether the battery 5 is in an over-discharge state. After adjusting the position of the battery protection plate 706, release the block 716, the spring 715 returns to its original state, and pushes the sliding block 714 to move in the opposite direction, so that the block 716 is re-engaged in the slot 717 on the side surface of the installation box 2, and the battery protection plate 706 is locked in the new position, ensuring that the battery protection plate 706 stably monitors and protects the battery 5 during operation. The heat absorption plate 802 is tightly fixed to the heat dissipation slot 801 On the inside, the heat generated by the battery protection plate 706 when working is conducted to the heat absorbing plate 802 itself, realizing the initial accumulation and absorption of heat. The conduction plate 803 efficiently conducts the heat absorbed by the heat absorbing plate 802 to the heat dissipation plate 804. The heat dissipation plate 804 has a large surface area and can further disperse the conducted heat. The heat sink 805 is fixed on the upper surface of the heat dissipation plate 804 at equal intervals. The heat sink 805 greatly increases the surface area in contact with the air. As a medium for heat transfer, the air will exchange heat with the heat sink 805 and take away the heat on the heat sink 805, thereby achieving a heat dissipation effect. The bump 806 further increases the surface area of ​​the heat sink 805. The heat generated by the battery protection board 706 can be quickly dissipated into the surrounding environment, maintaining the overall low-temperature operating state of the battery protection board 706, ensuring that its internal circuit works stably and reliably, and enabling components that are more sensitive to temperature, such as the over-discharge identification module 707, to function accurately. The mounting plate 602 is slid and pushed along the mounting groove 601 above the base 1. When the mounting plate 602 drives the shielding cover 603 to move, the mounting block 604 on one side surface of the shielding cover 603 also moves together. When the mounting block 604 moves to the position corresponding to the positioning column 606 fixedly connected to the base 1, the positioning column 606 will slide into the positioning groove 605 opened on one side surface of the mounting block 604.
