After continuous research, design, and repeated trial and improvement of samples, a practical new device is finally created.
[0043] Please refer to Figs. 1 to 3 The embodiment of the present application provides a glue pouring protection device, which comprises a shell 1 and a battery management system control board.
[0044] The outer casing 1 has an opening, which is actually the installation entrance for the first control board 2 and the second control board 3 to be installed in the outer casing. A first wire-locking groove group 11 and a second wire-locking groove group 12 are provided on the opposite sides of the opening.
[0045] The first control board 2 and the second control board 3 are sequentially installed into the outer casing 1, with the first control board 2 closer to the bottom wall of the outer casing 1. The first connecting wire group 31 connected to the second control board 3 is inserted into the first wire-locking groove group 11, and the second connecting wire group 32 connected to the second control board 3 is inserted into the second wire-locking groove group 12, thus separating the first control board 2 and the second control board 3 from each other. The outer casing 1 is filled with sealant for sealing the first control board 2 and the second control board 3. It should also be noted that the sealant fills the gap between the first control board 2 and the second control board 3, thereby maintaining the first control board 2 and the second control board 3 in an insulated state.
[0046] The installation steps of the glue-potting protection device in this embodiment are as follows:
[0047] ①Insert the first control board 2 into the outer casing 1.
[0048] ② The second control board 3 is installed into the outer casing 1, and the first connecting wire group 31 connected to the second control board 3 is inserted into the first wire slot group 11, and the second connecting wire group 32 connected to the second control board 3 is inserted into the second wire slot group 12, so that the first control board 2 and the second control board 3 are kept insulated and separated.
[0049] ③ Inject sealant into the outer casing 1, and the sealant submerges the top of the second control board 3, so that both the first control board 2 and the second control board 3 are sealed.
[0050] In this embodiment, both the first control board 2 and the second control board 3 are installed into the housing 1 along the opening. The first connecting wire group 31 connected to the second control board 3 is inserted into the first wire-clamping groove group 11, and the second connecting wire group 32 connected to the second control board 3 is inserted into the second wire-clamping groove group 12, thus achieving insulation separation between the first control board 2 and the second control board 3. Then, sealant is injected into the housing 1 to completely seal the first control board 2 and the second control board 3. The sealant injection protection device in this embodiment can insulate the first control board and the second control board within the same housing 1, reducing the installation volume and improving the safety of the first control board 2 and the second control board 3.
[0051] It should also be noted that the mounting structure of the outer shell 1, the first control board 2, and the second control board 3 in this embodiment can further simplify assembly and improve assembly efficiency. That is, the first control board 2 is positioned by the bottom wall of the outer shell 1, and the second control board 3 is positioned and assembled by the first connecting wire group 31 and the second connecting wire group 32.

[0055] Optionally, the first control panel 2 is an MCU control panel, and the second control panel 3 is a battery charging and discharging control panel. The MCU control panel can support mainstream communication modes on the market, such as UART communication, CAN communication and RS485 communication, etc.; and the battery charging and discharging control panel can support charging and discharging of commonly used ternary lithium batteries.
[0056] Optionally, the housing 1 is a transparent shell. In the glue filling process, whether there is a bubble inside can be directly observed, thereby avoiding the glue filling protection device with unqualified glue filling.
[0057] Optionally, the shell 1 is provided with a front flange 15 and a rear flange 16, and the front flange 15 and the rear flange 16 are both provided with fixing holes to facilitate the fixing of the shell 1 on the two-wheeled vehicle.
