[0024] The following disclosure provides many different implementations or examples for carrying out different structures of this application. To simplify the disclosure of this application, the components and arrangements of specific examples are described below. Of course, these are merely examples and are not intended to limit this application.

[0025] In small-box module solutions, due to internal space constraints, battery modules must be suspended within the box. The battery cells cannot be placed directly at the bottom of the box, and structural adhesives cannot be used to bond them due to design or manufacturing requirements. The current solution of simply fixing the battery module to the module bracket using cable ties has significant drawbacks: the lack of effective fixing and limiting structures for the cells in the height direction causes the battery module to fail to maintain stability during vibration, ultimately failing modal testing and failing to meet performance standards.

[0026] According to the first aspect of this application, please refer to Figure 1This application provides a battery pack, including a housing 100, a support assembly 200, and a battery module 300. The housing 100 provides physical protection for the battery module 300 and facilitates installation. The support assembly 200 supports the battery module 300 and limits its position in the Z-direction of gravity. The battery module 300 combines multiple battery cells to provide higher voltage, capacity, and power output compared to a single battery cell. The housing 100 includes multiple sidewalls 110 extending along the Z-direction of gravity, which are sequentially connected to form a receiving cavity 120. The support assembly 200 is disposed within the receiving cavity 120 and connected to the sidewalls 110. The battery module 300 is detachably disposed within the receiving cavity 120. The battery module 300 includes a battery pack 310 and a plate 320. The plate 320 is connected to the battery pack 310. The plate 320 is provided with a mounting groove 3211, the opening of which faces the side wall 110. A portion of the support component 200 is inserted into the mounting groove 3211 to limit the plate 320 along the gravity direction Z. It can be understood that the mounting groove 3211 facing the side wall 110 means that the opening of the mounting groove 3211 faces the gravity direction Z, that is, the direction of the mounting groove 3211 intersects the gravity direction Z. The plate 320 is connected to the battery pack 310, and the support component 200 is connected to the side wall 110, with a portion of the support component 200 inserted into the mounting groove 3211, thereby limiting the battery module 300 in the gravity direction Z through the support component 200.

[0027] It should be noted that the housing 100 includes a top plate and a bottom plate arranged opposite each other along the gravity direction Z, two side walls 110 arranged opposite each other along the first direction X, and two side walls 110 arranged opposite each other along the second direction Y. The top plate, bottom plate, and four side walls 110 enclose a receiving cavity 120. That is, the housing 100 has a cuboid structure. One of the four side walls 110 is a movable side wall 110 to facilitate the loading and unloading of the battery module 300. Additionally, to better illustrate the internal structure of the battery pack, Figure 1 One of the sidewalls 110 is not shown.

[0028] It should be noted that the main function of the battery pack 310 is to connect multiple battery cells together to form a whole, in order to provide the required voltage and capacity.

[0029] In some embodiments, please refer to Figure 2The battery pack 310 has a terminal side 311, which is a key area for achieving charging and discharging connections in the battery pack 310, and typically integrates electrode terminals and related conductive structures. To further improve the electrical safety of the battery pack, a mounting groove 3211 is located at the end of the plate 320 away from the terminal side 311 in the gravity direction Z. It can be understood that the support assembly 200 is located near the end of the plate 320 away from the terminal side 311, which increases the creepage distance between the terminal side 311 and the support assembly 200. This effectively reduces the risk of accidental electrical connection between the live parts of the terminal side 311 and the support assembly 200 due to insulation failure, avoiding safety hazards such as leakage and short circuits.

[0030] In some embodiments, please refer to Figure 1 and Figure 2 The plate 320 includes two end plates 321, which are disposed opposite to each other on both sides of the battery pack 310 along the first direction X and are both connected to the battery pack 310. The two end plates 321 together provide lateral support and structural fixation for the battery pack 310. To accommodate the installation and positioning function of the support assembly 200, a mounting groove 3211 is provided at the end of the end plate 321 away from the terminal post 311, and the mounting groove 3211 penetrates the end plate 321 along the first direction X, so that the support assembly 200 can enter from one side of the end plate 321 and exit from the other side in the first direction X, forming a stable interlocking structure. It is understood that each end plate 321 is provided with a mounting groove 3211, and the mounting grooves 3211 on the two end plates 321 are in corresponding positions, so that the support assembly 200 can be inserted from the mounting groove 3211 of one end plate 321 to the mounting groove 3211 of the other end plate 321 in the first direction X, so as to form a stable interlocking structure.

[0031] Corresponding to the housing 100, among the multiple side walls 110, there are two first walls 111. The two first walls 111 are arranged opposite each other along the second direction Y, and the opening of the mounting groove 3211 faces the first wall 111. The two first walls 111 serve as the fixed base for the support assembly 200. The side of the support assembly 200 away from the battery pack 310 is connected to the first wall 111, thereby forming a support structure extending along the first direction X within the receiving cavity 120. When the battery module 300 is installed into the receiving cavity 120, part of the support assembly 200 can be inserted into the mounting grooves 3211 of the two end plates 321. By means of the fixed relationship between the support assembly 200 and the first wall 111 and the insertion relationship between the support assembly 200 and the mounting groove 3211, the battery module 300 is reliably limited in the gravity direction Z.

[0032] It should be noted that the two end plates 321 abut against the two sides of the battery pack 310 respectively. The two end plates 321 and the battery pack 310 can be tied and fixed by cable ties 400, so that the three form a compact battery module 300 with good vibration resistance. This facilitates subsequent loading and unloading operations and reduces the risk of loosening of the internal components of the battery module 300.

[0033] In some embodiments, please refer to Figure 1 The structure of the plate 320 is further optimized. In addition to the two end plates 321, a support plate 322 is added. The support plate 322 is connected to the two end plates 321 and the battery pack 310 respectively, and the terminal post side 311 is located on the side of the battery pack 310 away from the support plate 322. On the one hand, it can connect the two end plates 321 into an integral frame, improving the support strength of the plate 320 for the battery pack 310; on the other hand, it can further strengthen the overall structural stability of the battery module 300 through its connection with the battery pack 310.

[0034] To accommodate the insertion and positioning of the support component 200, a connecting groove 3221 is provided on the support plate 322. The opening of the connecting groove 3221 faces the first wall 111 of the housing 100, meaning that the opening of the connecting groove 3221 faces the direction of gravity Z. In other words, the direction of the opening of the mounting groove 3211 intersects the direction of gravity Z. The connecting groove 3221 communicates with the mounting grooves 3211 on the two end plates 321 respectively, forming a plug-in groove 330, in which part of the support component 200 is inserted. When the battery module 300 is installed into the receiving cavity 120, part of the structure of the support component 200 can be directly inserted into the insertion slot 330. Compared with relying solely on the mounting slot 3211 on the end plate 321, the overall through-hole of the insertion slot 330 allows the support component 200 to fit more tightly with the plate 320, further improving the reliability of the battery module 300 in the Z-direction of gravity, and enhancing the battery module 300's resistance to displacement in a vibration environment.

[0035] It should be noted that the connection between the support plate 322 and the battery pack 310 can be achieved by adhesive bonding. This connection method does not require additional drilling or fasteners, and can form a tight and reliable connection without damaging the outer shell structure of the battery pack 310 or occupying too much assembly space. At the same time, the buffering properties of the adhesive can absorb vibration energy to a certain extent, reducing the hard collision between the battery pack 310 and the support plate 322 caused by vibration, and indirectly improving the vibration resistance of the battery module 300.

[0036] In some embodiments, please refer to Figure 1 and Figure 3The support assembly 200 includes two brackets 210 arranged opposite each other along the second direction Y. Each bracket 210 is connected to a first wall 111, forming a symmetrical and stable support structure. It should be noted that the bracket 210 is generally L-shaped, which can achieve the function of fixed extension and limiting in a limited space, adapting to the compact layout requirements of small box modules.

[0037] Suitable, such as Figure 3 As shown, in the gravity direction Z, the end plate 321 has two mounting slots 3211 at the end opposite to the pole post side 311. The two mounting slots 3211 are located on both sides of the end plate 321 in the second direction Y, and the openings of the two mounting slots 3211 face opposite directions, with the opening of each mounting slot 3211 facing its adjacent first wall 111.

[0038] Specifically, the bracket 210 includes a first connecting portion 211 and a second connecting portion 212, meaning that the two sides of the L-shaped bracket 210 correspond to the first connecting portion 211 and the second connecting portion 212, respectively. The first connecting portion 211 is located between the battery module 300 and the first wall 111 and is connected to the first wall 111, providing a stable mounting base for the entire bracket 210. The second connecting portion 212 is connected to the first connecting portion 211 perpendicularly or at a preset angle and extends towards the battery pack 310. At least a portion of the second connecting portion 212 is inserted into the insertion slot 330. When the battery module 300 is installed into the receiving cavity 120, at least a portion of the second connecting portion 212 will be inserted into the insertion slot 330 of the plate 320. With the rigid support of the L-shaped structure and the cooperation of the first connecting portion 211 being fixed and the second connecting portion 212 being inserted, the displacement of the battery module 300 in the direction of gravity Z is reliably limited.

[0039] In some embodiments, please refer to Figure 4 and Figure 5 To better illustrate the internal structure of the battery pack, Figure 4 One sidewall 110 is not shown. The plate 320 includes two end plates 321, which are disposed opposite to each other on both sides of the battery pack 310 along the first direction X and are both connected to the battery pack 310. The two end plates 321 together provide lateral structural support for the battery pack 310.

[0040] To accommodate the installation and positioning of the support assembly 200, a mounting groove 3211 is provided at the end of the end plate 321 away from the terminal post 311. The mounting groove 3211 extends through the end plate 321 along the second direction Y, and the opening of the mounting groove 3211 is located on the side of the end plate 321 opposite to the battery pack 310, forming an outward-facing insertion channel. It can be understood that each end plate 321 has a mounting groove 3211, and the openings of the mounting grooves 3211 on the two end plates 321 face away from each other.

[0041] Corresponding to the housing 100, among the multiple side walls 110, there are two first walls 111, which are arranged opposite each other along the first direction X, and the opening of the mounting groove 3211 faces the first wall 111; the support assembly 200 forms a support structure extending along the second direction Y. It should be noted that the support assembly 200 can be connected to the first wall 111 or directly connected to the bottom plate of the housing 100, thus achieving a stable fixing effect.

[0042] When the battery module 300 is inserted into the receiving cavity 120 from the second direction Y, part of the support component 200 can be inserted into the mounting groove 3211 along the second direction Y. By means of the fixed relationship between the support component 200 and the first wall 111 or the fixed relationship between the support component 200 and the base plate, as well as the insertion and engagement of the support component 200 and the mounting groove 3211, the battery module 300 is effectively limited in the gravity direction Z, and the stability of the battery module 300 in the vibration environment is further optimized.

[0043] In some embodiments, such as Figure 4 As shown, the structure of the plate 320 is further improved by including a support plate 322 in addition to the two end plates 321. The support plate 322 is connected to the two end plates 321 and the battery pack 310, which not only connects the two end plates 321 into a whole, enhancing the structural rigidity of the plate 320, but also forms a stable connection with the battery pack 310, improving the overall integrity of the battery module 300; it also provides effective support for the battery pack 310. At the same time, the terminal post side 311 of the battery pack 310 is designed to be on the side opposite to the support plate 322. This layout can reduce structural interference between the terminal post side 311 and the support plate 322.

[0044] It should be noted that the connection between the support plate 322 and the battery pack 310 can be achieved by adhesive bonding. This connection method does not require additional drilling or fasteners, and can form a tight and reliable connection without damaging the outer shell structure of the battery pack 310 or occupying too much assembly space. At the same time, the buffering properties of the adhesive can absorb vibration energy to a certain extent, reducing the hard collision between the battery pack 310 and the support plate 322 caused by vibration, and indirectly improving the vibration resistance of the battery module 300.

[0045] In some embodiments, please refer to Figure 4 and Figure 6 The support assembly 200 includes two brackets 210 arranged opposite each other along the first direction X. Each bracket 210 is disposed between the end plate 321 and the first wall 111. Each bracket 210 can be connected to one of the first walls 111 respectively, or both brackets 210 can be connected to the base plate. The end of the bracket 210 away from the corresponding first wall 111 is inserted into the mounting groove 3211.

[0046] It should be noted that each bracket 210 extends along the second direction Y, and the bracket 210 is L-shaped overall. This enables fixed extension and limiting within a limited space, adapting to the compact layout requirements of small box modules. Specifically, the bracket 210 includes a first connecting part 211 and a second connecting part 212, that is, the two sides of the L-shaped bracket 210 correspond to the first connecting part 211 and the second connecting part 212, respectively. The first connecting part 211 is located between the end plate 321 and the first wall 111. The side of the first connecting part 211 away from the end plate 321 is connected to the first wall 111, or the first connecting part 211 extends to connect with the bottom plate of the box 100, providing a stable installation base for the entire bracket 210. The second connecting part 212 is connected to the first connecting part 211 perpendicularly or at a preset angle, and extends towards the end plate 321. At least a portion of the second connecting part 212 is inserted into the mounting groove 3211.

[0047] When the battery module 300 is installed into the receiving cavity 120 along the first direction X, at least a portion of the second connecting part 212 will be inserted into the mounting groove 3211. With the rigid support of the L-shaped structure, the fixing of the first connecting part 211 to the first wall 111 or the bottom plate, and the engagement of the second connecting part 212, the displacement of the battery module 300 in the direction of gravity Z is reliably limited.

[0048] In some embodiments, the two end plates 321 and the support plate 322 are integrally formed. This allows the two end plates 321, i.e., the support plate 322, to form an inseparable integral structure, which not only eliminates the assembly process between the end plates 321 and the support plate 322, avoiding the risk of structural failure due to loose connections, but also improves the overall structural strength and rigidity of the plate body 320. The integrally formed plate body 320 can more evenly distribute stress when subjected to force, thereby better supporting the battery pack 310 and cooperating with the support assembly 200 to achieve positioning.

[0049] According to a second aspect of this disclosure, a vehicle is provided that includes the aforementioned battery pack. The vehicle possesses all the beneficial effects of the aforementioned battery pack, which will not be elaborated further herein.

[0050] The vehicle may be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this disclosure does not make any specific restrictions.

[0051] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
