Therefore, they should not be understood as limitations on the present utility model.

[0030] In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more than two. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] In one embodiment of the present invention, Figure 1-5 As shown, a buffered battery tray is provided, including a tray body 10, a placement seat 20, a first buffer seat 30 and a second buffer seat 40: a fixed cavity 11 is formed inside the tray body 10. The placement seat 20 is arranged in the fixed cavity 11. A plurality of groups of partitions 21 are provided on the placement seat 20. A first buffer layer 22 for buffering the battery module is provided on both sides of the partition 21. The first buffer seat 30 is arranged in a plurality of groups, and the plurality of groups of first buffer seats 30 are equidistantly distributed on the placement seat 20, and the first buffer seat 30 is located between two adjacent groups of partitions 21. The first buffer seat 30 is used for buffering the battery module. The second buffer seat 40 is arranged between the placement seat 20 and the tray body 10, and is used for buffering the placement seat 20.

[0032] By providing the first buffer layer 22, the first buffer seat 30 and the second buffer seat 40, when the battery module is placed on the placement seat 20 during transportation, the battery cells of the battery module are buffered and fixed by the first buffer layer 22, so as to avoid direct collision or extrusion between the battery cells or between the battery cells and the placement seat 20, thereby improving the service life of the battery module seat. At the same time, under the action of the second telescopic rod 32 and the second spring 33 in the first buffer seat 30, the battery cells are initially buffered, and then under the action of the connecting rod of the second buffer seat 40, the first slider 42 and the second slider 43, the battery cells and the placement seat 20 are further buffered, thereby reducing the impact force on the battery cells, avoiding damage to the battery cells, and improving the service life of the battery module.

[0033] Preferably, multiple groups of adjustment components are provided between the first buffer layer 22 and the partition 21. The multiple groups of adjustment components are equidistantly distributed on the partition 21. By providing the adjustment components, the clamping space of battery modules of different sizes can be adjusted by the adjustment components to adapt to battery modules of different sizes, and the battery modules can also be clamped and fixed to avoid collision between the battery cells of the battery module or between the battery cells and the placement seat 20, thereby improving the service life of the battery module.

[0034] Specifically, the adjustment component includes a first telescopic rod 23. The first telescopic rod 23 is arranged between the first buffer layer 22 and the partition 21. An elastic block 24 is sleeved on the outside of the first telescopic rod 23, and the elastic block 24 is located between the first buffer layer 22 and the partition 21. The elastic block 24 is an elastic rubber block. The distance between the first buffer layer 22 and the partition 21 is adjusted by the first telescopic rod 23 and the elastic block 24, so that the placement cavity between the two first buffer layers 22 can adapt to battery modules of different sizes. At the same time, the impact force acting on the battery cell is also buffered by the first buffer layer 22 and the elastic block 24, and the impact force is reduced one by one by the first buffer layer 22 and the elastic block 24, so that the damage to the battery cell is minimized and the service life of the battery module is improved.

[0035] Furthermore, a second buffer layer 25 is provided on the two side walls of the placement seat 20. The second buffer layer 25 can be made of a silicone material or a sponge rubber material, which can be selected according to actual production needs. By providing the second buffer layer 25, the second buffer layer 25 fits the outer side of the battery cell of the battery module, and plays a role in fixing and buffering the battery cell, reducing the impact force on the battery cell, avoiding direct collision between the battery cell and the inner wall of the placement seat 20, and improving the service life of the battery module.

[0036] Furthermore, a plurality of groups of bumps 26 are disposed outside the first buffer layer 22. The bumps 26 are sponge rubber blocks, which absorb and disperse the impact force on the battery cell, effectively reducing the impact force and increasing the service life of the battery module.

[0037] Preferably, multiple groups of placement cavities for placing battery modules are formed between multiple groups of partitions 21 and the placement seat 20. Multiple groups of placement cavities are equidistantly distributed in the placement seat 20. The cells in the battery module are placed in the placement cavities, so that the cells can be stably installed in the placement cavities, avoiding collision between the cells, and improving the service life of the battery module.

[0038] Specifically, the first buffer seat 30 includes a buffer plate 31. Two sets of second telescopic rods 32 are provided at the bottom end of the buffer plate 31. A second spring 33 is sleeved on the outer side of the second telescopic rod 32, and the second spring 33 is used for buffering the buffer plate 31. By setting the first buffer seat 30, during transportation, the buffer plate 31 is squeezed by the battery cell of the battery module. Under the action of the second telescopic rod 32 and the second spring 33, the buffer plate 31 generates a certain displacement and elastic rebound force, so that the battery cell can be stably installed in the placement cavity, avoiding collision between the battery cells or between the battery cell and the placement seat 20 due to shaking, thereby improving the service life of the battery module.

[0039] Furthermore, an installation cavity is provided between the second telescopic rod 32 and the placement seat 20, and two sets of second telescopic rods 32 are symmetrically distributed in the installation cavity. The second spring 33 is located between the installation cavity and the buffer plate 31. By symmetrically distributing the second telescopic rods 32 in the installation cavity, the stability of the buffer plate is improved, so that the battery cell is more stable during the buffering process, and the protection effect of the battery cell is enhanced.

[0040] Preferably, the second buffer seat 40 includes a sliding rod 41 disposed in the tray body 10. The sliding rod 41 is provided with a first slider 42 and a second slider 43. A third spring 44 is connected between one end of the first slider 42 and the tray body 10. A fourth spring 45 is connected between one end of the second slider 43 and the tray body 10. A fifth spring 46 is provided between the first slider 42 and the second slider 43. The first slider 42 and the second slider 43 are respectively connected to the bottom end of the placement seat 20 through a connecting rod. During transportation, the placement seat 20 drives the first slider 42 and the second slider 43 to be relatively far away on the sliding rod 41, and the first slider 42 and the second slider 43, under the action of the third spring 44 and the fourth spring 45, cause the placement seat 20 to generate a certain displacement and elastic rebound force, relieve the impact force on the placement seat 20, so that the placement seat 20 can be stably installed in the fixed cavity 11, avoid collision between the battery cells or between the battery cells and the placement seat 20 due to shaking, and improve the service life of the battery module. At the same time, by providing the fifth spring 46 , when the first slider 42 and the second slider 43 are relatively close to each other, the interaction force between the two is relieved, so that the placement seat 20 is more stable, and the stability of the placement seat 20 is improved.

[0041] Furthermore, the tray body 10 is provided with a first slide groove 47 and a second slide groove 48. The first slider 42 is slidably connected in the first slide groove 47. The second slider 43 is slidably connected in the second slide groove 48. By providing the first slide groove 47 and the second slide groove 48, the travel of the first slider 42 and the second slider 43 is limited, and the first slider 42 and the second slider 43 are also guided, thereby improving the sliding stability of the first slider 42 and the second slider 43.

Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model.
