The battery assembly is mounted on the upper end of the battery pack base 1 via a control component. Each battery pack assembly includes four movable seats 13. The control component includes a control panel 20 and four push seats 22. A partition frame 11 is located within the enclosure 2 at the upper end of the battery pack base 1. The partition frame 11 has a cross-shaped structure, dividing the enclosure 2 into four interval areas 12. The four movable seats 13 are horizontally positioned within the four interval areas 12, and the cross-sectional area of ​​each interval area 12 is larger than that of the movable seats 13. An auxiliary sliding groove 17 is provided on one side of each interval area 12. An auxiliary slider 18 is provided on one side of the lower end of each movable seat 13.

The receiving radio station is located in the interval area 12 and is provided with a receiving groove 16 on one side. The movable seat 13 is provided with a receiving bus 15 on the side near the receiving groove 16. The receiving bus 15 is inserted into the receiving groove 16. A sealing gasket is provided on the side of the movable seat 13 near the receiving groove 16. A control groove 19 is opened in the battery pack base 1. A control disk 20 is horizontally inserted in the control groove 19. A control tooth 21 is provided at the upper end of the control disk 20. The control tooth 21 is arranged in a planar spiral structure. A strip groove 35 is opened on one side of the interval area 12, which is connected to the control groove 19. The strip groove 35 is arranged in the same direction as the auxiliary slide 17. A push seat 22 is provided at the lower end of the movable seat 13. The push seat 22 is inserted into the control groove 19 through the strip groove 35. The lower end of the push seat 22 is provided with a meshing tooth groove. The meshing tooth groove of the push seat 22 is meshed and connected to one side of the control tooth 21.

[0041] By controlling the engagement of the worm gear 25 with the control panel 20, the self-limiting mechanism between the structures can be automatically completed in the non-drive state, maintaining the stable power connection of the four movable seats 13.

[0042] Example 3

[0043] Based on Embodiment 2, the cover plate 8 is synchronously controlled. The synchronization component includes a synchronization cylinder 23 and a lifting rod 26.

[0044] Example 4

[0045] Based on Embodiment 3, the up-and-down movement of the cover plate 8 is controlled. The cover plate 8 is horizontally positioned above the battery pack base 1 via a guide assembly. The guide assembly includes several guide boxes 6. Two guide boxes 6 are vertically positioned on each of the four sides of the upper end of the battery pack base 1. A guide groove is opened on one side of each guide box 6. A guide post 7 is vertically and movably inserted into each guide box 6. The guide post 7 is connected to the emergency shield 5 and one side of the cover plate 8, respectively. A docking frame 28 is provided at the lower end of the cover plate 8. The docking frame 28 is correspondingly positioned to the partition frame 11. A lifting rod 26 is vertically positioned at the lower center of the docking frame 28. The lower end of the lifting rod 26 is movably inserted into the synchronous cylinder 23. Two synchronous spiral grooves 24 are symmetrically provided on the inner circumference of the synchronous cylinder 23. Several lifting sliders 27 are symmetrically provided on one side of the lifting rod 26 placed inside the synchronous cylinder 23, and the several lifting sliders 27 are movably inserted into the two synchronous spiral grooves 24, respectively.

[0046] When the electrical connectors 15 of the four movable seats 13 are disengaged from the electrical connector slots 16, the cover plate 8 moves downwards synchronously, blocking the upper end of the enclosure plate 2 and the ventilation hole 3, making the four partition areas 12 independent, thus reducing the risk in the event of local temperature runaway and spontaneous combustion.

[0047] In addition, high-temperature resistant sealing gaskets are provided at the contact points between the cover plate 8 and the enclosure plate 2, and at the contact points between the docking frame 28 and the partition frame 11.

[0048] In its natural state, the cover plate 8 has a gap with the enclosure plate 2, which facilitates air flow and provides safety protection for the top of the battery pack 14, thereby improving the safety of the battery pack 14.

[0049] The upper end of the synchronous spiral groove 24 can be set through the upper end of the synchronous cylinder 23 to facilitate the disassembly and assembly of the cover plate 8 and the maintenance and replacement of the infrared sensing module 30.

[0050] Example 5

[0051] Based on Embodiment 4, temperature detection of the battery pack 14 is completed. The monitoring component includes four infrared sensing modules 30, which are symmetrically arranged on the side of the cover plate 8 near the battery pack base 1. The four infrared sensing modules 30 are correspondingly arranged with four movable seats 13. A conical guide groove 29 is opened on the side of the cover plate 8 near the battery pack 14. The four infrared sensing modules 30 are respectively located in the center of the four conical guide grooves 29. A diversion groove 31 is opened on both sides of the cover plate 8 near the conical guide grooves 29. One side of the diversion groove 31 is connected to the conical guide groove 29. The conical guide channel 29 has a blowout channel 32. A connecting pipe 33 is inserted into the side of the cover plate 8 near the conical guide channel 29. The connecting pipe 33 is U-shaped and two diversion channels 31 are connected to each side of the connecting pipe 33. A control box 9 is horizontally installed at the top of the cover plate 8. Two inlet pipes 10 are horizontally symmetrically installed on both sides of the control box 9. Four diversion pipes 34 are horizontally symmetrically installed on the four sides of the control box 9. One side of each of the four diversion pipes 34 is connected to one side of the four connecting pipes 33. When temperature runaway is detected, intelligent sensing and rapid control can be performed.

[0052] An electrically controlled valve can be installed inside the shunt pipe 34. When liquid nitrogen gas or lime is introduced into the inlet pipe 10, the shunt pipe 34 and the connecting pipe 33 at the corresponding positions can be connected to achieve local safety protection.

[0053] In addition, the enclosure panel 2, cover plate 8, partition frame 11 and docking frame 28 are all made of explosion-proof materials that are heat-resistant, flame-retardant and explosion-proof.

[0054] During use, the temperature of the battery pack 14 is monitored by the non-contact infrared sensor module 30. When the temperature of the battery pack 14 runs out of control;

[0055] The backup power control drives the worm gear 25 to rotate, which in turn drives the worm gear 25 to control the control disk 20 to rotate through the worm teeth 36. When the control disk 20 rotates, it drives the control teeth 21 to drive and control the four push seats 22, so that the four movable seats 13 move along the strip groove 35 and the auxiliary slide groove 17, thereby disconnecting the power supply 15 from the power supply groove 16 and completing the power disconnection connection of the battery pack 14 above the four movable seats 13.

[0056] While the movable seat 13 moves, the synchronous cylinder 23 rotates synchronously with the control panel 20. Under the sliding connection between the lifting slider 27 and the synchronous spiral groove 24, the cover plate 8 is pulled to move horizontally downward along several guide boxes 6. The docking frame 28 docks and presses with the partition frame 11. The emergency shielding plate 5 descends to seal the ventilation hole 3 of the enclosure plate 2, and performs sealing and isolation treatment on the four partition areas 12.

[0057] After the interval 12 is sealed, the location of temperature runaway is determined based on the monitoring data of the infrared sensing module 30. Liquid nitrogen gas and lime are then introduced into the corresponding shunt pipe 34 and connecting pipe 33 through the access pipe head 10. The gas and lime enter the corresponding interval 12 from the shunt trough 31 and the blow-out trough 32 and come into contact with the battery pack 14 to suppress the potential danger of temperature runaway.

[0058] When the battery pack 14 is in normal use, cooling gas is similarly introduced into the conical guide groove 29 through the connection pipe head 10. The cooling gas is evenly blown towards the battery pack 14 under the guiding effect of the conical guide groove 29.

[0059] The cooling gas blown towards the battery pack 14 descends and flows out from the vent 3, driving airflow within the spacer 12 and reducing the possibility of temperature runaway in the battery pack 14.

[0060] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
