DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] This embodiment provides a battery pack tray structure, and its structural diagram is as follows Figures 1-4As shown, it includes a pallet main body 1, a plurality of connecting ear blocks 7 are arranged on the outer wall of the pallet main body 1, a partition 2 is arranged in the pallet main body 1, the partition 2 is distributed along the width direction of the pallet main body 1, and a plurality of partitions 2 are arranged side by side. The multiple partitions 2 arranged side by side in the pallet main body 1 can separate the multiple battery packs to prevent short circuits caused by battery damage, leakage, etc. When thermal runaway occurs in the battery pack, the heat propagation speed is slowed down, the current distribution between battery cells or modules is balanced, and the battery performance degradation or damage caused by excessive local current is avoided, thereby improving safety performance. A slide groove 3 is provided on the bottom wall inside the pallet body 1. The slide groove 3 is distributed along the length direction of the pallet body 1. There are multiple slide grooves 3 arranged side by side. Each of the majority slide grooves 3 is slidably embedded with sliders 4 of the same number as the partitions 2. Multiple partitions 2 are respectively assembled on multiple sliders 4. By utilizing the sliding cooperation between the sliders 4 and the slide grooves 3 and fixing the partitions 2 on the sliders 4, the position of the partitions 2 can be adjusted to facilitate the assembly of the battery pack.

[0026] In this embodiment, the slider 4 is set to a "convex" shaped structure to prevent the slider 4 from falling off the slide groove 3. A connecting bolt 8 is passed through the position on the partition 2 corresponding to the slide groove 3, and a threaded hole 15 is opened on the slider 4 to match the thread of the connecting bolt 8. The partition 2 can be fixed on the slider 4 by using the threaded cooperation between the connecting bolt 8 and the threaded hole 15.

[0027] Furthermore, auxiliary positioning bolts 10 are vertically threaded at both ends of the partition 2, and rubber strips 11 are embedded at positions on the inner bottom wall of the support plate body 1 aligned with the auxiliary positioning bolts 10. The rubber strips 11 are distributed in opposite directions along the length of the support plate body 1. Tightening the auxiliary positioning bolts 10 and pressing the rubber strips 11 against each other can assist in positioning the partition 2 inside the support plate body 1, thereby separating and positioning multiple battery packs.

[0028] In a further embodiment, a groove 16 is provided at the bottom of the slider 4. The groove 16 extends through both side walls of the slider 4 and communicates with the chute 3. A through groove 6 is provided on the end face of the support plate body 1. A partition 13 is provided in the through groove 6. Both ends of the chute 3 communicate with the through groove 6. Providing a groove 16 at the bottom of the slider 4 that communicates with the chute 3, and providing through grooves 6 at both ends of the support plate body 1 that communicate with the chute 3, facilitates ventilation and heat dissipation at the bottom of the battery pack, wherein the partition 13 acts to block dust and mosquitoes. Bosses 9 are provided on both sides of the partition 2. The height of the bosses 9 is less than that of the partition 2. After the battery pack is installed, the bosses 9 can be used to create a gap between the partition 2 and the battery pack, thereby facilitating heat dissipation from the sides of the battery pack.

[0029] In a further embodiment, end plates 5 are provided at both ends of the pallet body 1, and fixing bolts 12 threadedly inserted into the pallet body 1 are passed through the end plates 5. Protrusions 14 engaged with the pallet body 1 are provided at both ends of the end plates 5. After the end plates 5 are removed, the slider 4 can be removed or assembled from the through groove 6, which is also conducive to the assembly of the battery pack into the pallet body 1.

[0030] Working principle: When in use, multiple partitions 2 arranged side by side in the support body 1 can be used to separate multiple battery packs to prevent short circuits caused by battery damage, leakage, etc. When thermal runaway occurs in the battery pack, the heat propagation speed is slowed down, the current distribution between battery cells or modules is balanced, and the battery performance degradation or damage caused by excessive local current is avoided, thereby improving safety performance. The position of the partition 2 can be adjusted by sliding the slider 4 with the slide groove 3 and fixing the partition 2 on the slider 4, thereby facilitating the assembly of the battery pack. By tightening the auxiliary positioning bolts 10 and pressing against the rubber strips 11, the partition 2 can be assisted in positioning in the support plate body 1, which is used to separate and position multiple battery packs. A groove 16 connected to the slide 3 is provided at the bottom of the slider 4, and through grooves 6 connected to the slide 3 are provided at both ends of the support plate body 1, which is beneficial to ventilation and heat dissipation at the bottom of the battery pack. The bosses 9 arranged on both sides of the partition 2 leave a gap between the battery pack and the partition 2, which is beneficial to ventilation and heat dissipation on the side of the battery pack. The overall structure is flexible, convenient for assembly of the battery pack, and provides the battery pack with an installation space with good heat dissipation effect.
