After the overall assembly is completed, place the outer protective shell 1 on the bottom of the car, and electrically connect the power supply to the car's wires through wires.

[0031] As a further implementation of this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, an inner protective frame 2 is arranged on the inner side of the outer protective shell 1, and a sealing cover plate 3 is arranged above the inner protective frame 2, a reserved card slot 4 is opened on the side wall of the outer protective shell 1, a heat conducting plate 5 is arranged at the bottom of the inner cavity of the outer protective shell 1, and a heat dissipation fin 6 is arranged at the bottom of the heat conducting plate 5, one end of the heat dissipation fin 6 will extend to the outside of the bottom of the outer protective shell 1, but the extension length will not be too long, a protective plate 7 is arranged on the inner side of the outer protective shell 1, and a first damper 8 is arranged in the middle section of the side wall of the protective plate 7.

An insulating pad 20 is fixedly connected to one end of the second damper 19, and a rubber bump 21 is arranged on the other side of the insulating pad 20. The rubber bump 21 is equidistant from the inner side of the battery arrangement cavity 13. The rubber protrusions 21 are evenly distributed on the side wall of the insulating pad 20, and the inside of the rubber protrusions 21 is made of rubber material. A second spring 22 is fixedly connected to a corner of one side of the insulating pad 20, an adapter seat 23 is fixedly installed at one end of the partition 18, and a third spring 24 is fixedly connected to the inner cavity of the adapter seat 23, and a blocking rod 25 is fixedly connected to the other end of the third spring 24, and an auxiliary slide plate 26 is sleeved on the outer side of one end of the blocking rod 25.

[0034] When the battery pack needs to be assembled, the partition 18 will first be extended to the inner side of the inner protective frame 2 through the inner side of the through groove 14. At the same time, one end of the partition 18 will be engaged in the notch reserved on the inner wall of the inner protective frame 2 to achieve preliminary positioning of the partition 18. Then the adapter seat 23 set at the other end of the partition 18 will be engaged with the inner side of the through groove 14 to achieve positioning of the partition 18. At this time, the position of the baffle rod 25 is on one side of the baffle groove 15, so the lateral force applied to the baffle rod 25 disappears. Then the reverse force generated by the deformation of the third spring 24 will push the baffle rod 25 in the reverse direction, and then input one end of the baffle rod 25 into the inner side of the baffle groove 15, so as to achieve positioning of the partition 18. The setting of the auxiliary slide plate 26 is used to improve the stability of the baffle rod 25 during the lateral movement. Qualitatively, when multiple partitions 18 are assembled, the battery packs are placed in the divided battery arrangement cavities 13 respectively, and the battery packs will laterally squeeze the insulating pad 20 to achieve lateral movement of the insulating pad 20. At this time, the insulating pad 20 will laterally press the second damper 19 and the second spring 22, and then the reverse force generated by the deformation of the two can effectively prevent the battery pack from lateral shaking, thereby improving the stability of the battery pack itself.

[0036] When the battery pack is placed on the inner side of the inner protective frame 2, the sealing cover plate 3 is snap-connected to the top opening of the inner protective frame 2. At this time, the sealing seat 27 is snap-connected to the inner protective frame 2. When the two are fully snap-connected, a plurality of blocks 28 equidistantly distributed along the center point of the sealing seat 27 can be snap-connected to the inner side of the groove 16 to achieve a preliminary connection between the two. Subsequently, a plurality of positioning bolts 29 are passed through the sealing cover plate 3 to extend to the inner side of the bolt groove 17.

[0037] Specific working principle:

[0038] When in use, the partition 18 will first pass through the inner side of the through groove 14 and be extended to the inner side of the inner protective frame 2. At the same time, one end of the partition 18 will be engaged in the notch reserved on the inner wall of the inner protective frame 2 to achieve the initial positioning of the partition 18. Then the adapter seat 23 set at the other end of the partition 18 will be engaged with the inner side of the through groove 14 to achieve the positioning of the partition 18. At this time, the position of the blocking rod 25 is on one side of the blocking groove 15, so the lateral force applied to the blocking rod 25 disappears. Then the reverse force generated by the deformation of the third spring 24 will push the blocking rod 25 in the reverse direction, and then input one end of the blocking rod 25 into the inner side of the blocking groove 15, so as to achieve the positioning of the partition 18. The setting of the auxiliary slide plate 26 is used to increase the blocking rod 25. Stability during lateral movement. After the multiple partitions 18 are assembled, the battery packs are placed in the divided battery arrangement chambers 13 respectively, and the battery packs will laterally squeeze the insulating pad 20 to achieve lateral movement of the insulating pad 20. At this time, the insulating pad 20 will laterally press the second damper 19 and the second spring 22, and then the reverse force generated by the deformation of the two can effectively prevent the battery pack from lateral shaking, thereby improving the stability of the battery pack itself. At the same time, since the internal structure of the rubber protrusion 21 is made of rubber material, the multiple rubber protrusions 21 set in combination can further protect the battery pack to prevent the outer surface of the battery pack from being damaged by friction with the insulating pad 20, and the multiple battery packs are electrically connected through wires. And the inner side of the insulating pad 20 can be reserved with holes for the wires to pass through, and then when the battery pack is arranged, the sealing cover plate 3 is snap-connected to the top opening of the inner protection frame 2. At this time, the sealing seat 27 is snap-connected with the inner protection frame 2, and when the two are fully snap-fitted, a plurality of snap blocks 28 equidistantly distributed along the center point of the sealing seat 27 can be snap-fitted to the inner side of the groove 16 to achieve a preliminary connection between the two, and then a plurality of positioning bolts 29 are passed through the sealing cover plate 3 so that they extend to the inner side of the bolt groove 17. At this time, by rotating the positioning bolts 29, a threaded connection between the positioning bolts 29 and the bolt groove 17 can be achieved. After the connection is completed, the inner protection frame 2 can be sealed, which has an effective dustproof and waterproof effect. Then the inner protection frame 2 is placed outside. The inner side of the protective shell 1, and because the outer protective shell 1 is sleeved on the outer side of the inner protective frame 2, and the outer protective shell 1 is snap-connected with the bottom of the car through the reserved card slot 4, when the car base encounters a bump during driving, the collision object will first contact the outer protective shell 1, and then the inner protective frame 2 can be effectively protected to ensure the safety of the battery pack in the inner protective frame 2 and achieve the purpose of anti-collision. When the inner protective frame 2 shakes laterally on the inner side of the outer protective shell 1, the inner protective frame 2 will push the protective plate 7 connected to one side thereof, and then the protective plate 7 will push the rotating rod 9 under the action of the lateral force of the inner protective frame 2, so that the rotating rod 9 pushes the sliding sleeve 10 connected to the other end through the connecting ear, so that the sliding sleeve 10 slides laterally along the cross bar 11.When the sleeve 10 slides laterally, the first spring 12 will be deformed accordingly. At the same time, the movement of the protective plate 7 will squeeze the first damper 8. Then, the reverse force generated by the deformation of the first spring 12 and the first damper 8 can achieve the purpose of buffering protection, thereby preventing the inner protective frame 2 from shaking significantly during the driving of the vehicle, affecting the stability of the internal battery pack, causing the wire to fall off, etc., and improving the practicality of the entire device. Since a heat conducting plate 5 is provided at the bottom of the inner cavity of the outer protective shell 1, and the heat conducting plate 5 is attached to the bottom of the inner protective frame 2, the heat generated by the battery during operation can be transferred by the heat conducting plate 5, and dissipated through multiple heat dissipation fins 6 evenly distributed at the bottom, thereby achieving the purpose of heat dissipation.
