Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] For a further understanding of the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0033] Please refer to Figures 1-8, the present invention provides a technical solution: a BMS battery management system module with heat dissipation function, including an installation box 1, a sealing cover 6 is arranged on the top of the installation box 1, a pipeline 3 is fixedly installed on one side of the installation box 1, the pipeline 3 is communicated with the inside of the installation box 1, a heat dissipation fan 2 is fixedly installed at the air inlet end of the pipeline 3, a wind guiding piece 14 is fixedly installed at one end of the pipeline 3 inside the heat dissipation fan 2, a protective net 7 is fixedly installed on one side of the installation box 1, and a PCB circuit board 11 is arranged inside the installation box 1.

[0034] When dissipating heat from the PCB circuit board 11, start the heat dissipation fan 2, so that the air blown by the heat dissipation fan 2 enters the inside of the installation box 1 through the pipeline 3, and then is discharged through the protective net 7, so as to facilitate the air to move from the upper and lower sides of the PCB circuit board 11, so as to facilitate cooling the PCB circuit board 11, so as to prevent the PCB circuit board 11 from overheating, facilitate dissipating heat from the upper and lower sides of the PCB circuit board 11, and maximize the heat dissipation effect on the PCB circuit board 11.

[0035] Two fixed limiting blocks 18 are fixedly installed inside the installation box 1, clamping blocks 19 are slidably connected inside both of the two fixed limiting blocks 18, the upper sides of the two clamping blocks 19 are both inclined, grooves 20 are opened on the opposite sides of the two clamping blocks 19, the PCB circuit board 11 is located inside the two grooves 20, a blocking plate 22 is fixedly installed at one end of the clamping block 19 inside the fixed limiting block 18, the blocking plate 22 is slidably connected inside the fixed limiting block 18, a second elastic spring 21 is fixedly installed inside the fixed limiting block 18, and one end of the second elastic spring 21 close to the blocking plate 22 is fixedly connected to the blocking plate 22.

[0036] When fixing the PCB circuit board 11, place the PCB circuit board 11 on the two clamping blocks 19, and then press down the PCB circuit board 11, so that the PCB circuit board 11 squeezes the inclined surfaces of the two clamping blocks 19, so that the clamping blocks 19 slide into the inside of the fixed limiting block 18 and squeeze the second elastic spring 21. Then when the PCB circuit board 11 coincides with the groove 20, the clamping block 19 will be reset by the elastic force of the second elastic spring 21, so as to clamp the PCB circuit board 11, so as to facilitate fixing the PCB circuit board 11, improve the convenience of fixing the PCB circuit board 11, and prevent the PCB circuit board 11 from shaking inside the installation box 1.

[0037] Inside the installation box 1, a guide rod 13 is fixedly installed. A circular hole 12 is formed in the PCB circuit board 11. The guide rod 13 is slidably connected inside the circular hole 12. A sliding ring 17 is slidably sleeved on the guide rod 13. A return spring 16 is movably sleeved on the guide rod 13. The upper end of the return spring 16 is fixedly connected to the sliding ring 17, and the lower end of the return spring 16 is fixedly connected to the inside of the installation box 1.

[0038] When the PCB circuit board 11 moves downward, the circular hole 12 is aligned with the guide rod 13. Then, when the PCB circuit board 11 moves downward, the PCB circuit board 11 will squeeze the sliding ring 17, causing the sliding ring 17 to slide on the guide rod 13 and compress the return spring 16. When the two clamping blocks 19 no longer squeeze the PCB circuit board 11, the PCB circuit board 11 will be reset by the elastic force of the return spring 16, and then the PCB circuit board 11 will be pushed out from the guide rod 13, facilitating the disassembly of the PCB circuit board 11, reducing the difficulty of disassembling the PCB circuit board 11, and increasing the speed of disassembling the PCB circuit board 11.

[0039] On both sides of the installation box 1, support outer rods 5 are fixedly installed. Inside both support outer rods 5, limit plates 9 are slidably connected. On both limit plates 9, first elastic springs 10 are fixedly installed. One end of each of the two first elastic springs 10 away from the two limit plates 9 is fixedly connected to the inside of the two support outer rods 5 respectively. On one side of each of the two limit plates 9, a hook 4 is fixedly installed. The hook 4 slidably penetrates through the support outer rod 5 and extends to the outside of the support outer rod 5.

[0040] When fixing the installation box 1, pull the two hooks 4, causing the two hooks 4 to move away from each other, and then causing the two limit plates 9 to slide inside the two support outer rods 5, stretching the two first elastic springs 10. Then, place the installation box 1 on the installation plate and stop pulling the two hooks 4. Then, the two hooks 4 will be reset by the pulling force of the two first elastic springs 10, and the two hooks 4 will clamp on the installation plate, thus realizing the fixation of the installation box 1, facilitating the installation of the installation box 1, and facilitating the operation of the staff.

[0041] The inside of the installation box 1 is rotatably connected with a rotating shaft 8. One end of the rotating shaft 8 located inside the installation box 1 is fixedly sleeved with an eccentric wheel 23. Two clamping grooves 24 are formed on the eccentric wheel 23. Two sealing plates 15 are slidably connected inside the installation box 1. Lifting plates 25 are fixedly installed at the bottoms of the two sealing plates 15. The lifting plates 25 are slidably connected inside the installation box 1. Third elastic springs 27 are fixedly installed on the two lifting plates 25. One end of each of the two third elastic springs 27 facing away from each other is fixedly connected to the inside of the installation box 1. Clamping blocks 26 are fixedly installed on one side of the two lifting plates 25 facing each other. The clamping blocks 26 are in conformity with the clamping grooves 24.

[0042] Rotate the rotating shaft 8 to drive the eccentric wheel 23 to rotate, so that the eccentric wheel 23 squeezes the two lifting plates 25, causing the two lifting plates 25 to move away from each other inside the installation box 1, squeezing the two third elastic springs 27, pushing the two sealing plates 15 out of the inside of the installation box 1, and enabling the two sealing plates 15 to block the protective net 7. After the eccentric wheel 23 rotates 90 degrees, the clamping blocks 26 will enter the inside of the clamping grooves 24, realizing the support for the two sealing plates 15, facilitating the sealing plates 15 to block the protective net 7, preventing external dust from entering the inside of the installation box 1 and affecting the heat dissipation effect of the PCB circuit board 11.

[0043] Working principle:

[0044] Start the cooling fan 2, so that the air from the cooling fan 2 blows into the inside of the installation box 1 through the pipeline 3 and is discharged through the protective net 7, facilitating the air to move from the upper and lower sides of the PCB circuit board 11 and cooling the PCB circuit board 11.

[0045] When fixing the PCB circuit board 11, place the PCB circuit board 11 on the two clamping blocks 19, then press down the PCB circuit board 11, causing the PCB circuit board 11 to squeeze the inclined surfaces of the two clamping blocks 19, making the clamping blocks 19 slide into the inside of the fixing limiting block 18 and squeezing the second elastic spring 21. When the PCB circuit board 11 coincides with the groove 20, the clamping blocks 19 will reset by the elastic force of the second elastic spring 21 to clamp the PCB circuit board 11.

[0046] When the PCB circuit board 11 moves downward, the circular hole 12 is aligned with the guide rod 13. Then, when the PCB circuit board 11 moves downward, the PCB circuit board 11 will squeeze the sliding ring 17, so that the sliding ring 17 slides on the guide rod 13 and squeezes the return spring 16. When the two clamping blocks 19 no longer squeeze the PCB circuit board 11, the PCB circuit board 11 will be reset by the elastic force of the return spring 16, and then the PCB circuit board 11 will be pushed out from the guide rod 13, which is convenient for disassembling the PCB circuit board 11.

[0047] When fixing the installation box 1, pull the two hooks 4, so that the two hooks 4 move away from each other. Then, the two limit plates 9 slide inside the two support outer rods 5, stretching the two first elastic springs 10. Then, place the installation box 1 on the installation plate and stop pulling the two hooks 4. Then, the two hooks 4 will be reset by the pulling force of the two first elastic springs 10, so that the two hooks 4 clamp on the installation plate, thus realizing the fixation of the installation box 1.

[0048] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
