[0019] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0020] like Figure 1-Figure 4 As shown, a BMS protection board with OTA function provided in this embodiment includes a mounting frame 1, fixed corner brackets 2 are arranged at the bottom of the four corners of the outer wall of the mounting frame 1, a second reserved hole 9 is arranged at the top of the fixed corner bracket 2, a protection layer frame 3 is buckled and installed in the second reserved hole 9, fixed plug posts 5 are arranged around the inner wall of the protection layer frame 3, and a control board body 4 is arranged directly below the fixed plug posts 5.

[0021] The fixed angle bracket 2 and the mounting frame 1 are integrally cast and made of metal material. The fixed angle bracket 2 is L-shaped, which supports the mounting frame 1 to a certain height, which is beneficial to the installation of the control board circuit and the ventilation and heat dissipation of the circuit board.

[0022] The four corners of the bottom of the protective layer frame 3 are welded with plug-in locking buckle columns 8, and the plug-in locking buckle columns 8 are detachably connected to the second reserved holes 9. The protective layer frame 3 is a hollow structure, which not only protects the circuit board, but also facilitates the placement of the top structure of the circuit board.

[0023] The first reserved hole 7 is aligned with the hole position on the control body, and the first reserved hole 7 can lock and fix the plug post 5.

[0024] The top four corners of the protection layer frame 3 are provided with layer frame combination mounting holes 6, and the layer frame combination mounting holes 6 are used to install another set of protection layer frames 3, so as to realize overlapping installation of circuit boards.

[0025] The working principle of this device: when this device is used, the four sets of fixed angle codes 2 of the mounting frame 1 are reinforced with screws on the holes on the outer wall of the battery pack, and then the protective layer frame 3 is pulled out from the second reserved hole 9 on the mounting frame 1 by plugging and unplugging the locking buckle column 8 through appropriate external force, and the control board body 4 is aligned and placed on the mounting frame 1, and the holes are aligned, and the protective layer frame 3 then inserts the fixed plug column 5 into the hole position of the circuit board, and finally inserts it into the first reserved hole 7, and at the same time, the plugging and locking buckle column 8 is again inserted into the second reserved hole 9 and locked, so that the circuit board can be firmly installed on the external side of the battery pack, and then the monitoring circuit of the battery pack is connected to the input interface of the circuit board to complete the installation. When a new monitoring circuit needs to be added, it can be continued and installed through the layer frame combination mounting hole 6 on the top of the protective layer frame 3, which is more convenient and can quickly realize the overlapping installation of circuit boards, which is more practical.

[0026] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
