Detailed Implementation

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] This application provides a square plastic tray for battery cells, such as Figures 1 to 6 As shown, the pallet body 1 is integrally injection molded. The pallet body 1 has at least one receiving groove 2. The receiving groove 2 includes a first groove and a second groove. The first groove is located at the top of the pallet body 1, and the second groove is located at the side of the pallet. The two opposite side walls of the receiving groove 2 are provided with a plurality of first heat dissipation holes 23 in the longitudinal direction. The plurality of first heat dissipation holes 23 penetrate the side walls of the receiving groove 2 in the transverse direction. The bottom of the receiving groove 2 is provided with a plurality of second heat dissipation holes 24 in the longitudinal direction. The outer periphery of the second heat dissipation holes 24 is provided with a boss 25. The boss 25 is provided with a plurality of third heat dissipation holes 26 in the longitudinal direction. The second heat dissipation holes 24 and the third heat dissipation holes 26 penetrate the bottom of the receiving groove 2 in the vertical direction.

[0025] like Figure 3 and Figure 4 As shown, each of the two opposite sidewalls of the receiving groove 2 has a pair of guide grooves 21. The two pairs of guide grooves 21 are arranged opposite to each other. Each pair of guide grooves 21 includes two guide grooves 21 arranged vertically. The guide groove 21 includes multiple first grooves 211 and multiple second grooves 212. The multiple first grooves 211 and multiple second grooves 212 are arranged longitudinally at intervals. The second groove 212 located at the end is connected to the second groove opening. The first groove 211 has a circular structure and the second groove 212 has a long strip structure. The vertical cross-sectional length of the first groove 211 is greater than the vertical cross-sectional length of the second groove 212.

[0026] like Figure 5 and Figure 6As shown, a plurality of baffle plates 3 are slidably connected in the two groups of guide grooves 21, and a battery cell groove for placing the square battery cell is formed between two adjacent baffle plates 3. The baffle plate 3 comprises a first rod body 31, a plate body 32 and a second rod body 33 connected in sequence from top to bottom. The first rod body 31 is parallel to the second rod body 33. A displacement slot 311 is formed on each of the two longitudinal sides of the first rod body 31 and extends in the vertical direction. The first end of the first rod body 31 and the first end of the second rod body 33 are respectively arranged in a pair of guide grooves 21. The second end of the first rod body 31 and the second end of the second rod body 33 are respectively arranged in another pair of guide grooves 21. The first rod body 31 and the second rod body 33 are slidably connected in the second groove body 212 and matched with the first groove body 211. The baffle plate 3 is locked by being embedded in the first groove body 211. The two sides of the plate body 32 are respectively formed with a heat dissipation channel 22 and a plurality of first heat dissipation holes 23 in communication with the heat dissipation channel 22. Specifically, the tray body 1 made of plastic material has a certain elasticity. An operator can push the first rod body 31 and the second rod body 33 according to the size of the square battery cell, so that they are slidably connected in the second groove body 212 and then slid into the appropriate first groove body 211, thereby completing the fixation of the baffle plate 3.

[0027] In a specific implementation scenario, the number of accommodation grooves 2 is two. The first groove openings of the two accommodation grooves 2 are arranged on the same level, and the second groove openings are arranged on the same level. The plurality of first heat dissipation holes 23 of the two accommodation grooves 2 are in communication with each other.

[0028] In the specific use process of the square battery cell plastic tray, the operator can push the first rod body 31 and the second rod body 33 to move in the second groove body 212 according to the need, and then clamp them in the appropriate first groove body 211 to fix the baffle plate 3. The space for placing the square battery cell is formed between the two adjacent baffle plates 3 and has an adjustable size. The heat dissipation channel 22 and the first heat dissipation hole 23 form a heat dissipation passage extending to the outside for heat dissipation of the two sides of the square battery cell. The bottom of the square battery cell is placed on the boss 25 and forms a gap with the second heat dissipation hole 24. The second heat dissipation hole 24 and the third heat dissipation hole 26 are used for heat dissipation of the bottom of the square battery cell. Compared with the prior art, the square battery cell plastic tray can flexibly accommodate square battery cells of various sizes.

[0029] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application.
