The orientation terms such as "first direction, second direction" are defined based on Figure 2 the directions indicated by the arrows corresponding to the "first direction" and "second direction" marked in

[0025] According to some embodiments of the present disclosure, a hierarchical display structure for a battery pack is provided. Referring to Figures 1 to 4 as shown in

[0026] the hierarchical display structure includes a first support member 5 and a second support member 6. The first support member 5 extends along the first direction, one end is used to abut against the inner bottom wall of the tray 1, and the other end is used to support the battery cell group 2. The second support member 6 extends along the first direction, one end is used to abut against the upper surface of the battery cell group 2, and the other end is used to support the liquid cooling plate 3.

[0027] In the exemplary embodiment provided by the present disclosure, referring to Figure 2As shown, both the first support member 5 and the second support member 6 can be configured as columnar structures. With this arrangement, the first support member 5 supports the battery cell group 2, facilitating the separation of the battery cell group 2 from the tray 1, and the second support member 6 supports the liquid cooling plate 3, facilitating the separation of the battery cell group 2 from the liquid cooling plate 3, which is beneficial for observing and studying the structures of the tray 1, the battery cell group 2, and the liquid cooling plate 3. In addition, using a columnar structure is conducive to the lightweight of the structure.

[0028] In the exemplary embodiment provided by the present disclosure, referring to Figure 2 and Figure 3 As shown, the first support member 5 may include a first support body 51. One end of the first support body 51 is provided with a first support portion 52, and the other end is provided with a second support portion 53. The first support portion 52 abuts against the inner bottom wall 11 of the tray 1, and the second support portion 53 is used to support the battery cell group 2. In the above technical solution, the first support portion 52, the second support portion 53, and the first support body 51 can be integrally processed and formed, ensuring the structural strength of the first support member 5, and thus being beneficial to improving the support performance of the first support member 5.

[0029] In the exemplary embodiment provided by the present disclosure, referring to Figure 3 As shown, the first support portion 52 can be configured as a disc structure, and the diameter of the first support portion 52 is greater than the diameter of the first support body 51. By this setting, the contact area between the first support member 5 and the inner bottom wall 11 is increased, thereby improving the stability of the support. Here, in order to ensure the reliability of the support, the first support portion 52 can be adhesively connected to the inner bottom wall 11. In this way, it can not only prevent the first support portion 52 from shifting relative to the inner bottom wall 11 or detaching from the inner bottom wall 11 during an accidental collision, but also facilitate the disassembly and assembly of the first support member 5.

[0030] In the exemplary embodiment provided by the present disclosure, referring to Figure 2 and Figure 3 As shown, the second support portion 53 can be configured as a U-shaped structure to form a receiving groove 531 for supporting the battery cell group 2. By this setting, the battery cell group 2 can pass through the receiving groove 531 to be constrained in the receiving groove 531, thereby ensuring the stability of the support of the second support portion 53 for the battery cell group 2.

[0031] In the exemplary embodiment provided by the present disclosure, referring to Figure 2As shown, the first support member 5 has a plurality of them, and the plurality of first support members 5 are arranged at intervals in the second direction, the second direction is perpendicular to the first direction and the second direction corresponds to the length direction of the battery cell group 2. Among them, the number of the first support members 5 can be set to two, three or four. In practical applications, it can be flexibly set according to the size of the battery cell group 2, and the present disclosure does not make specific limitations on this. By setting like this, multiple parts of the battery cell group 2 are effectively supported, improving the support performance for the battery cell group 2.

[0032] In the present disclosure, the battery cell group 2 includes a plurality of battery cells 21, and the plurality of battery cells 21 are all sequentially inserted through the second support portions 53 of the respective first support members 5 in the second direction, and the plurality of battery cells 21 are stacked in the third direction (not shown in the figure) to form the battery cell group 2, wherein the third direction is perpendicular to both the second direction and the first direction.

[0033] In the exemplary embodiment provided by the present disclosure, referring to Figure 4 As shown, the second support member 6 may include a second support body 61, and third support portions 62 are provided at both ends of the second support body 61. The third support portions 62 are configured as disc structures, and the diameter of the third support portions 62 is greater than the diameter of the second support body 61. By setting like this, the third support portions 62 are abutted against the battery cell group 2 or the liquid cooling plate 3. Since the diameter of the third support portions 62 is greater than the diameter of the second support body 61, the second support member 6 has a larger abutting area with the battery cell group 2. Similarly, the second support member 6 also has a larger abutting area with the liquid cooling plate 3, thereby improving the stability among the second support member 6, the battery cell group 2 and the liquid cooling plate 3.

[0034] In the present disclosure, there are a plurality of second support members 6, and the plurality of second support members 6 can be arranged in a matrix. In this way, the stability of the liquid cooling plate 3 is ensured. In addition, the second support members 6 and the battery cell group 2 and the liquid cooling plate 3 can be connected by an adhesive method to improve the reliability of the support.

[0035] In the exemplary embodiment provided by the present disclosure, referring to Figure 2 As shown, the hierarchical display structure may include a mounting plate 7 and a third support member 81. The mounting plate 7 is arranged between the battery cell group 2 and the liquid cooling plate 3 through the third support member 81, and the mounting plate 7 is used to support the bus bar 4. In the above technical solution, the third support member 81 supports the mounting plate 7, and the mounting plate 7 is used to support the bus bar 4 to display the bus bar 4.

[0036] In the exemplary embodiment provided by the present disclosure, referring to Figure 2As shown, the hierarchical display structure may further include a towing line 8, which is used to connect the mounting plate 7 and the liquid cooling plate 3 to suspend the mounting plate 7 above the liquid cooling plate 3. Here, the towing line 8 and the third support member 81 may be respectively disposed on two opposite sides of the mounting plate 7. Due to the arrangement of the towing line 8, the mounting plate 7 can be stably located between the battery cell group 2 and the liquid cooling plate 3 through the cooperation of the towing line 8 and the third support member 81. In this way, the stability of the mounting plate 7 is ensured, the number of the third support members 81 is reduced, which is beneficial to the lightweight of the structure, and the display effect is improved.
