[0022] A first circular hole 7 through which a heat conducting strip 9 passes is formed at the top of the conveying bin 4. The conveying bin 4 communicates with the installation bin 2 through the first circular hole 7. A second circular hole 8 through which the heat conducting strip 9 passes is formed at the top of the installation bin 2. The suction bin 3 communicates with the installation bin 2 through the second circular hole 8. The inner diameters of the first circular hole 7 and the second circular hole 8 are both larger than the outer diameter of the heat conducting strip 9, and the heat conducting strip 9 is close to the battery body 5. The heat conducting strip 9 is made of a heat conducting material, such as aluminum, etc., which is adjusted according to the specific use situation. The heat conducting strip 9 can absorb the heat generated by the battery body 5. When the gas flows along the heat conducting strip 9 from bottom to top, the heat on the heat conducting strip 9 and the battery body 5 can be taken away.

[0023] A limiting plate 10 is fixedly connected to the top of the heat conducting strip 9, and the outer diameter of the limiting plate 10 is larger than the inner diameter of the second circular hole 8. The limiting plate 10 can close the second circular hole 8.

[0024] A first spring 16 is fixedly connected to the top of the limiting plate 10, and the top end of the first spring 16 abuts against the top of the suction bin 3. The first spring 16 is provided for the reset of the limiting plate 10 and other structures.

[0025] A baffle 12 is fixedly connected to the square box 11. The baffle 12 cooperates with the through hole 13.

[0026] The controller and its control principle are common existing technologies and will not be elaborated here.

[0027] A first square groove 17 is formed at one end of the housing 1. A first square cylinder 18 is fixedly connected inside the first square groove 17. The first square cylinder 18 communicates with the suction bin 3. A first support block 19 is fixedly connected to the inner wall of the first square cylinder 18. A motor 20 is fixedly connected to the first support block 19, and a fan 21 is fixedly connected to the motor 20.

The second square cylinder 27 communicates with the conveying bin 4. A through groove 28 is formed at the end of the second square cylinder 27 far from the conveying bin 4. A filter plate 29 is fixedly connected inside the through groove 28.

[0029] During actual use, when the temperature sensor detects that the temperature exceeds the set threshold, it transmits this information to the controller. The controller controls the electromagnet 15 to start, and the magnetic properties of the mutually approaching surfaces of the magnetic block 14 and the electromagnet 15 are the same. Under the repulsive force, the magnetic block 14 pushes the square box 11 and the baffle 12 to move upward, the through hole 13 is opened, and the bottom box 6 communicates with the conveying bin 4 through the through hole 13; at the same time, the limiting plate 10 moves upward, and the second round hole 8 is opened.

[0030] Start the motor 20, the motor 20 drives the fan 21 to rotate. Under the suction force, the external air enters the inside of the conveying bin 4 after being filtered by the filter plate 29, and then enters the inside of the suction bin 3 through the through hole 13, the bottom box 6, the first round hole 7, and the second round hole 8, and is discharged from the first square tube 18.

[0031] The gas flows along the heat conducting strip 9 from bottom to top, taking away the heat on the heat conducting strip 9 and the battery body 5, improving the heat dissipation efficiency of the battery body 5, and realizing the protection of the battery pack. Especially in the electromechanical equipment of new energy vehicles, the battery pack is one of its core components, thus ensuring the use safety of new energy vehicles.

[0032] Due to the difference in heat generation of the battery body 5, during the heat dissipation process of the present invention, the second round holes 8 and through holes 13 at other positions are in a closed state, and each battery body 5 can dissipate heat independently and specifically, avoiding mutual influence and improving the heat dissipation efficiency.

[0033] A rotating shaft 23 is fixedly connected to the first square tube 18. The rotating shaft 23 is located at one end of the first square tube 18 away from the suction bin 3. A flap 22 is rotatably connected to the rotating shaft 23. A circular groove 24 is formed on the inner wall of the first square tube 18.

One end of the torsion spring 25 is fixedly connected to the inner wall of the circular groove 24, and the other end of the torsion spring 25 is fixedly connected to the flap 22.

[0034] During heat dissipation, the motor 20 drives the fan 21 to rotate, and the suctioned gas is discharged from the first square tube 18. When the gas is discharged, it will push the flap 22 to turn outwards, so that the first square tube 18 is opened, which does not affect ventilation and heat dissipation. After the heat dissipation stops, the restoring elastic force of the torsion spring 25 makes the flap 22 reset, closing the first square tube 18 to prevent dust and the like from entering the inside of the housing 1.

[0035] A second support block 30 is fixedly connected to the inner wall of the second square tube 27. A second spring 31 is fixedly connected to the second support block 30. The end of the second spring 31 away from the second support block 30 is fixedly connected to the sealing plate 32.

[0036] During heat dissipation, under the suction force, the sealing plate 32 moves towards the second support block 30, facilitating the entry of external air into the interior of the second square tube 27. After heat dissipation ends, the restoring elastic force of the second spring 31 causes the sealing plate 32 to reset, closing the filter plate 29. When the sealing plate 32 contacts the filter plate 29 during the reset process, the filter plate 29 will vibrate, loosening the impurities accumulated outside the filter plate 29, facilitating subsequent cleaning by the operator.

[0037] The present invention also proposes a usage method for the vehicle battery pack protection device for electromechanical equipment, which is applied to the above-mentioned vehicle battery pack protection device for electromechanical equipment, and further includes the following operating steps: S1. Connection: At the heating position, the square frame 11 drives the limiting plate 10 to move upward through the heat conducting strip 9, and the conveying bin 4, the bottom box 6, the first round hole 7, the second round hole 8, and the suction bin 3 are connected. S2. Heat dissipation: The gas flows upward along the heat conducting strip 9, taking away the heat on the battery body 5. S3. Reset: The square frame 11 drives the limiting plate 10 to reset through the heat conducting strip 9.

[0038] Working principle: During actual use, when the temperature sensor detects that the temperature exceeds the set threshold, it transmits this information to the controller. The controller controls the electromagnet 15 to start. The magnetic properties of the mutually approaching surfaces of the magnetic block 14 and the electromagnet 15 are the same. Under the repulsive force, the square frame 11 and the baffle 12 are pushed upward by the magnetic block 14, and the through hole 13 is opened. The bottom box 6 is connected to the conveying bin 4 through the through hole 13. At the same time, the limiting plate 10 moves upward, and the second round hole 8 is opened.

[0039] Start the motor 20. The motor 20 drives the fan 21 to rotate. Under the suction force, the external air enters the interior of the conveying bin 4 after being filtered by the filter plate 29, and then enters the interior of the suction bin 3 through the through hole 13, the bottom box 6, the first round hole 7, and the second round hole 8, and is discharged from the first square tube 18.

[0040] During heat dissipation, the motor 20 drives the fan 21 to rotate. The suctioned gas is discharged from the first square tube 18. When the gas is discharged, it will push the flap 22 to turn outwards, opening the first square tube 18, which does not affect ventilation and heat dissipation. After heat dissipation stops, the restoring elastic force of the torsion spring 25 causes the flap 22 to reset, closing the first square tube 18 to prevent dust and the like from entering the interior of the housing 1.

[0041] During heat dissipation, under the suction force, the sealing plate 32 moves towards the second support block 30, facilitating the entry of external air into the interior of the second square tube 27. After heat dissipation ends, the restoring elastic force of the second spring 31 causes the sealing plate 32 to reset, closing the filter plate 29. When the sealing plate 32 contacts the filter plate 29 during the reset process, the filter plate 29 will vibrate, loosening the impurities accumulated outside the filter plate 29, facilitating subsequent cleaning by the operator.
