[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0024] Please refer to Figures 1 to 3 This application provides a battery pack bracket having intersecting first directions X, second directions Y, and third directions Z. The battery pack bracket includes a bottom frame 100, a top frame 110, multiple connecting beams 120, and multiple first diagonal braces 200 arranged along the third direction Z. The first directions X, second directions Y, and third direction Z are, respectively, the width direction, the length direction, and the height direction of the battery pack bracket.

[0025] The top frame 110 is spaced apart from the bottom frame 100 in the third direction Z. Both the top frame 110 and the bottom frame 100 can be rectangular frame structures, and the top frame 110 and the bottom frame 100 have the same dimensions. The first direction X is the same as the width direction of the top frame 110 and the bottom frame 100, and the second direction Y is the same as the length direction of the top frame 110 and the bottom frame 100, both extending in the same direction.

[0026] Each connecting beam 120 extends along a third direction Z and connects between the bottom frame 100 and the top frame 110 in the third direction Z, cooperating to form a receiving compartment 130. The receiving compartment 130 is located inside the battery pack bracket formed by the bottom frame 100, multiple connecting beams 120, and the top frame 110. The receiving compartment 130 can house the vehicle's high-voltage box, charging equipment, and water-cooling unit, with the high-voltage box and charging equipment arranged adjacent to each other. The battery pack 400 can be installed on the top frame 110. The high-voltage box and charging equipment are electrically connected to the battery pack 400, and the water-cooling unit, as an important component of the battery pack 400's liquid cooling system, is used to cool the battery pack 400. Thus, the battery pack 400 is mounted on the top frame 110 above the battery pack bracket, and the high-voltage box, charging equipment, and water-cooling unit are installed in the receiving compartment 130 within the battery pack bracket. This allows the battery pack 400, high-voltage box, charging equipment, and water-cooling unit to be integrated and installed within the battery pack bracket, forming an integrated, modular battery pack bracket assembly. Typically, the vehicle battery system and high-voltage box are supplied by the same manufacturer. Integrating the battery pack 400, charging equipment, and high-voltage box within the battery pack bracket not only saves on wiring cables for the high-voltage box but also facilitates modular assembly of the vehicle battery system and high-voltage box. Optionally, a first housing 170 covers the multiple connecting beams 120 between the bottom frame 100 and the top frame 110. That is, the first housing 170 can be installed around the perimeter of the battery pack bracket. The first housing 170 isolates the receiving compartment 130 of the battery pack bracket from the external environment, helping to protect the high-voltage box, charging equipment, and water-cooling components installed within the receiving compartment 130 from external bumps or impacts.

[0027] Each first diagonal brace 200 is connected between the bottom frame 100 and the top frame 110 in the third direction Z, and is positioned between two adjacent connecting beams 120 in the second direction Y. The extension direction of the first diagonal brace 200 is at an angle to the extension direction of the connecting beam 120. When the bottom frame 100 and the top frame 110 are rectangular frame structures, four connecting beams 120 can be provided, with the four connecting beams 120 respectively located at the four corners of the bottom frame 100 and the top frame 110. The angled arrangement of the first diagonal brace 200 and the connecting beam 120 can enhance the resistance to external deformation between the bottom frame 100 and the top frame 110, thereby increasing the strength of the battery pack bracket and providing stable support for the battery pack 400 on the top frame 110. It can also prevent damage to the high-voltage box, charging equipment, and water-cooling components in the housing 130 due to compression caused by deformation of the battery pack bracket.

[0028] Through the above technical solution, the bottom frame 100, connecting beam 120, and top frame 110 can form a housing 130 within the battery pack bracket. The housing 130 can integrate and accommodate the high-voltage box, charging equipment, and water-cooling components. The battery pack 400 can be installed on the top frame 110, thereby improving the integration and modularity of the battery pack bracket. By setting a first diagonal brace 200 at an angle to the connecting beam 120 between the top frame 110 and the bottom frame 100, the first diagonal brace 200 can be inclined between the bottom frame 100 and the top frame 110, increasing the strength of the battery pack bracket. This not only provides stable support for the battery pack 400 on the top frame 110, but also improves the deformation resistance of the housing 130, preventing the space inside the housing 130 from being squeezed under external forces, and preventing damage to the high-voltage box, charging equipment, and water-cooling units inside the housing 130 due to compression.

[0029] In some embodiments, please Figures 1 to 3 Further reference Figure 4 and Figure 5 The multiple first diagonal braces 200 include a first sub-diagonal brace 210 and a second sub-diagonal brace 211.

[0030] The first sub-bracing 210 is connected between the bottom frame 100 and the top frame 110 in the third direction Z. Multiple first sub-bracing 210s may be included, and the angle between the extension direction of different first sub-bracing 210s and the extension direction of the connecting beam 120 can be different. That is, the inclination degree of different first sub-bracing 210s can be different. By installing multiple first sub-bracing 210s with different inclination angles between the bottom frame 100 and the top frame 110, the first sub-bracing 210s can cooperate with the connecting beam 120 to provide various support forces for the bottom frame 100 and the top frame 110, which helps to improve the deformation resistance of the bottom frame 100 and the top frame 110.

[0031] The second sub-bracing 211 is connected between the bottom frame 100 and the top frame 110 in the third direction Z. Multiple second sub-bracing 211s may be included, and the angle between the extension direction of different second sub-bracing 211s and the extension direction of the connecting beam 120 can be different. That is, the inclination degree of different second sub-bracing 211s can be different. By installing multiple second sub-bracing 211s with different inclination angles between the bottom frame 100 and the top frame 110, the second sub-bracing 211s can cooperate with the connecting beam 120 to provide various support forces for the bottom frame 100 and the top frame 110, which helps to improve the deformation resistance of the bottom frame 100 and the top frame 110.

[0032] The extension direction of the first sub-diagonal brace 210 forms an angle with the extension direction of the second sub-diagonal brace 211. The first sub-diagonal brace 210 and the second sub-diagonal brace 211 can form a V-shape or a figure-eight shape. The V-shape or figure-eight shape of the first and second sub-diagonal braces 210 and 211 enhances the strength of the battery pack bracket and improves its resistance to deformation. It should be noted that when the first and second sub-diagonal braces 210 and 211 form a V-shape, the vertex of the angle formed by the V-shape is the intersection of the first and second sub-diagonal braces 210 and 211. A straight line runs along the third direction Z through this vertex, and the first and second sub-diagonal braces 210 and 211 are located on opposite sides of this straight line in the second direction Y. When the first sub-bracing 210 and the second sub-bracing 211 are in a V-shape, the extensions of the two sub-bracing 210 and the second sub-bracing 211 form an angle, and the intersection of their extensions is the vertex of this angle. A straight line passes through this vertex along the third direction Z, and the first sub-bracing 210 and the second sub-bracing 211 are located on either side of this straight line in the second direction Y. Thus, the first sub-bracing 210 and the second sub-bracing 211 can support the bottom frame 100 and the top frame 110 in a V-shape or a figure-eight shape, effectively improving the strength and deformation resistance of the battery pack bracket.

[0033] In some embodiments, please refer to Figures 1 to 5 The battery pack bracket also includes a first connector 212. The first connector 212 extends along a second direction Y and connects to the same end of the first sub-diagonal brace 210 and the second sub-diagonal brace 211, such that the first sub-diagonal brace 210 and the second sub-diagonal brace 211 are connected to the top frame 110 or the bottom frame 100 via the first connector 212. Specifically, the first connector 212 has a plate-like structure. The first connector 212 can connect portions of the first sub-diagonal brace 210 and the second sub-diagonal brace 211 into a single unit. By connecting the first connector 212 to the frame of the top frame 110 or the bottom frame 100, not only can the first sub-diagonal brace 210 and the second sub-diagonal brace 211 be connected as a whole, improving the overall integrity of the first sub-diagonal brace 210 and the second sub-diagonal brace 211, but also the first connector 212 can simultaneously connect the first sub-diagonal brace 210 and the second sub-diagonal brace 211 to the top frame 110 or the bottom frame 100, simplifying the installation process of the first sub-diagonal brace 210, the second sub-diagonal brace 211 and the top frame 110 or the bottom frame 100.

[0034] In some embodiments, please refer to Figures 1 to 5 The battery pack bracket also includes an auxiliary beam 140 and a second connector 213.

[0035] An auxiliary beam 140 extends along the third direction Z, connecting the bottom frame 100 and the top frame 110. The auxiliary beam 140 is also positioned between two adjacent connecting beams 120 in the second direction Y. The auxiliary beam 140, in conjunction with the connecting beams 120, enhances the support for the top frame 110 and the bottom frame 100, preventing deformation in the middle of the top and bottom frames 110. Optionally, the bottom frame 100 is provided with a second intermediate beam 111 along the first direction X. One end of the auxiliary beam 140 is fixed to the connection between the top frame 110 and the second intermediate beam 111, thereby improving the support at the connection between the top frame 110 and the second intermediate beam 111. It should be noted that a cross beam 112 and a strip 113 can also be provided inside the top frame 110. The cross beam 112 can fix the external wiring harness of the battery pack 400 on the top frame 110, facilitating cable management. The strip 113 is arranged inside the top frame 110 along the first direction X. The strip 113 facilitates the installation of components inside the storage compartment 130 and helps to make the layout of components such as high voltage boxes and charging equipment inside the storage compartment 130 more orderly.

[0036] The second connector 213 is connected to the end of the first sub-bracing 210 away from the first connector 212, and the second connector 213 is connected to the same end of the first sub-bracing 210 and the auxiliary beam 140, or the same end of the second sub-bracing 211 and the auxiliary beam 140. Specifically, the second connector 213 can simultaneously connect the first sub-bracing 210 and the auxiliary beam 140, as well as the second sub-bracing 211 and the auxiliary beam 140. The second connector 213 can connect the first sub-bracing 210 and the auxiliary beam 140, as well as the second sub-bracing 211 and the auxiliary beam 140, into a single unit. By connecting the second connector 213 to the frame of the bottom frame 100 or the top frame 110, not only can the first sub-diagonal brace 210 and the auxiliary beam 140, as well as the second sub-diagonal brace 211 and the auxiliary beam 140, be connected as a whole, improving the overall integrity of the first sub-diagonal brace 210, the second sub-diagonal brace 211 and the auxiliary beam 140, be connected to the bottom frame 100 or the top frame 110 at the same time by the second connector 213, simplifying the process of installing the first sub-diagonal brace 210, the second sub-diagonal brace 211 and the auxiliary beam 140 on the battery pack bracket.

[0037] In some embodiments, please continue to refer to Figures 1 to 5 The second connector 213 includes a first connector 2130 and a second connector 2131.

[0038] The first connecting portion 2130 extends along the second direction Y and is connected to the same end of the first sub-bracing 210 and the auxiliary beam 140, or the same end of the second sub-bracing 211 and the auxiliary beam 140. The second connecting portion 2131 extends along the first direction X and is connected to the first connecting portion 2130. Both the first connecting portion 2130 and the second connecting portion 2131 are plate-like structures.

[0039] The battery pack bracket also includes a first reinforcing beam 150, one end of which is connected to the second connecting portion 2131, and the other end is connected to the top frame 110 and the auxiliary beam 140. The first connecting portion 2130 is fitted and fixed to the frame of the bottom frame 100, and the second connecting portion 2131 is connected to the first reinforcing beam 150. Optionally, a transition portion 2132 for connecting the first connecting portion 2130 and the second connecting portion 2131 can also be provided between them. The transition portion 2132 can extend along the surface of the frame of the bottom frame 100 and connect the first connecting portion 2130 and the second connecting portion 2131 into one unit. The transition portion 2132 can increase the connection area between the second connecting member 213 and the frame of the bottom frame 100, thereby improving the connection reliability between the second connecting member 213 and the bottom frame 100.

[0040] Thus, by using the first connecting part 2130 and the second connecting part 2131, the connection difficulty between the first lower connector and the bottom frame 100 and the assembly frame 300 can be reduced according to the structural characteristics of the bottom frame 100 and the assembly frame 300, which helps to improve the connection efficiency between the first inclined beam and the bottom frame 100 and the assembly frame 300. In addition, the first reinforcing beam 150 is inclinedly disposed between the second connecting part 2131 and the top frame 110. The bottom end of the first reinforcing beam 150 is fixedly connected to the second connecting part 2131, and the top end of the first reinforcing beam 150 is connected to the top frame 110 and the auxiliary beam 140. As a result, the connection strength between the second connecting part 2131 and the top frame 110 and the auxiliary beam 140 can be increased, further improving the overall strength of the assembly frame 300 and the battery pack bracket.

[0041] In some embodiments, please refer to Figures 3 to 5 The battery pack bracket also includes an auxiliary rib 160, which is located at the end where the auxiliary beam 140 connects to the top frame 110, and is connected to both the auxiliary beam 140 and the top frame 110. The auxiliary rib 160 has a triangular plate-like structure. The auxiliary rib 160 enhances the connection strength between the auxiliary beam 140 and the top frame 110, enabling the auxiliary beam 140 to reliably support the top frame 110 over a long period.

[0042] In some embodiments, please Figures 3 to 5 Further reference Figure 6 and Figure 7The bottom frame 100 is provided with a first intermediate beam 101 extending along a first direction X. The battery pack bracket also includes a plurality of second diagonal braces 220, each of which is connected between the first intermediate beam 101 and the top frame 110 in a third direction Z. Specifically, in some applications, one end of the second diagonal brace 220 is connected to the bottom frame 100 via the first intermediate beam 101, and the other end of the second diagonal brace 220 is directly connected to the frame of the top frame 110. The second diagonal braces 220 can further enhance the connection strength between the bottom frame 100 and the top frame 110, and improve the deformation resistance of the entire battery pack bracket. Optionally, the end of the second diagonal beam connected to the top frame 110 can also be connected to a portion of the first diagonal brace 200, improving the integrity of the second diagonal brace 220 and the first diagonal brace 200, so that the second diagonal brace 220 can cooperate with the first diagonal beam to jointly enhance the connection strength and deformation resistance between the bottom frame 100 and the top frame 110, and improve the reliability of the battery pack bracket.

[0043] It should be noted that the housing 130 can be divided into two parts by the first intermediate beam 101 and the second diagonal brace 220. One part of the housing 130 is used to install the high-voltage box and charging equipment, and the other part of the housing 130 is used to install the water cooling equipment.

[0044] In addition, reinforcing beams 102 are provided on both sides of the first intermediate beam 101 in the second direction Y. The reinforcing beams 102 are arranged within the bottom frame 100 along the second direction Y. The reinforcing beams 102 can improve the support effect on the high-voltage box, charging equipment and water-cooled unit in the housing 130, and improve the load-bearing reliability of the battery pack bracket.

[0045] In some embodiments, please refer to Figures 1 to 5 The multiple second diagonal braces 220 include a third sub-diagonal brace 221 and a fourth sub-diagonal brace 222.

[0046] The third sub-diagonal brace 221 is connected between the first intermediate beam 101 and the top frame 110 in the third direction Z. The extension direction of the third sub-diagonal brace 221 is set at an angle to the extension direction of the connecting beam 120. By setting the third sub-diagonal brace 221 obliquely between the bottom frame 100 and the top frame 110, the third sub-diagonal brace 221 can cooperate with the connecting beam 120 to provide support for the bottom frame 100 and the top frame 110, which helps to improve the deformation resistance of the bottom frame 100 and the top frame 110.

[0047] The fourth sub-diagonal brace 222 is connected between the first intermediate beam 101 and the top frame 110 in the third direction Z. The extension direction of the fourth sub-diagonal brace 222 is set at an angle to the extension direction of the connecting beam 120. By setting the fourth sub-diagonal brace 222 obliquely between the bottom frame 100 and the top frame 110, the fourth sub-diagonal brace 222 can cooperate with the connecting beam 120 to provide support for the bottom frame 100 and the top frame 110, which helps to improve the deformation resistance of the bottom frame 100 and the top frame 110.

[0048] The extension direction of the third sub-diagonal brace 221 is set at an angle to the extension direction of the fourth sub-diagonal brace 222. The third sub-diagonal brace 221 and the fourth sub-diagonal brace 222 can form a V-shape or a figure-eight shape. The V-shape or figure-eight shape of the third sub-diagonal brace 221 and the fourth sub-diagonal brace 222 can enhance the strength of the battery pack bracket and improve its resistance to deformation. It should be noted that when the third sub-diagonal brace 221 and the fourth sub-diagonal brace 222 are V-shaped, the vertex of the angle formed by the V-shaped third sub-diagonal brace 221 and the fourth sub-diagonal brace 222 is the intersection point of the third sub-diagonal brace 221 and the fourth sub-diagonal brace 222. A straight line passing through this vertex along the third direction Z has the third sub-diagonal brace 221 and the fourth sub-diagonal brace 222 located on both sides of this straight line in the second direction Y. When the third sub-bracing 221 and the fourth sub-bracing 222 are in a V-shape, the extensions of the V-shaped third sub-bracing 221 and the fourth sub-bracing 222 form an angle, and the intersection of their extensions is the vertex of this angle. A straight line runs along the third direction Z through this vertex, and the third sub-bracing 221 and the fourth sub-bracing 222 are located on both sides of this straight line. Thus, the third sub-bracing 221 and the fourth sub-bracing 222 can support the bottom frame 100 and the top frame 110 in a V-shape or a V-shape, effectively improving the strength and deformation resistance of the battery pack bracket.

[0049] Therefore, the second diagonal brace 220 can work together with the first diagonal brace 200 to improve the overall strength of the battery pack bracket and prevent the battery pack bracket from deforming under external forces.

[0050] In some embodiments, please refer to Figure 4 and Figure 5 The battery pack bracket also includes a third connector 223, which extends along a first direction X and connects to the same end of the third sub-diagonal brace 221 and the fourth sub-diagonal brace 222, so that the third sub-diagonal brace 221 is connected to the first intermediate beam 101 or the top frame 110 via the third connector 223. Specifically, the third connector 223 is a plate-like structure. The third connector 223 can connect part of the third sub-diagonal brace 221 and the fourth sub-diagonal brace 222 into one unit. The connection between the third connector 223 and the first intermediate beam 101 not only connects the third sub-diagonal brace 221 and the fourth sub-diagonal brace 222 into one unit, improving the overall integrity of the third sub-diagonal brace 221 and the fourth sub-diagonal brace 222, but also allows the third sub-diagonal brace 221 and the fourth sub-diagonal brace 222 to the first intermediate beam 101 simultaneously via the third connector 223, simplifying the installation process of the third sub-diagonal brace 221, the fourth sub-diagonal brace 222, and the bottom frame 100.

[0051] In some embodiments, please refer to Figures 1 to 7The battery pack bracket also includes an assembly frame 300, which includes a first beam 310 and a second beam 320 connected to each other. The first beam 310 extends along a first direction X, and the second beam 320 extends along a second direction Y. Both the first beam 310 and the second beam 320 are connected to the bottom frame 100. Specifically, the assembly frame 300 is located on the side of the bottom frame 100 away from the top frame 110. The assembly frame 300 can be a rectangular or square structure, and there are two of each of the first beam 310 and the second beam 320. The two first beams 310 are connected to the bottom frame 100 along the first direction X, and the two second beams 320 are connected to the bottom frame 100 along the second direction Y. The second beam 320's connection along the second direction Y to the length of the bottom frame 100 provides stable support for the battery pack bracket. The first beam 310 can be connected to the vehicle to install the battery pack bracket on the vehicle, providing an installation location for the battery pack 400, high-voltage box, charging equipment and water-cooled unit required for normal vehicle operation.

[0052] In other embodiments, when the second connector 213 includes a first connecting portion 2130 and a second connecting portion 2131, the second connecting portion 2131 is connected to the first beam 310, thereby connecting one end of the first reinforcing beam 150 to the top frame 110 and the auxiliary beam 140, and the other end to the first beam 310 of the assembly frame 300. Thus, by using the first connecting portion 2130 and the second connecting portion 2131, the connection difficulty between the second lower connector and the bottom frame 100 and the assembly frame 300 can be reduced according to the structural characteristics of the bottom frame 100 and the assembly frame 300, which helps to improve the connection efficiency between the first diagonal brace 200 and the bottom frame 100 and the assembly frame 300. Furthermore, the first reinforcing beam 150 is inclined between the second connecting portion 2131 and the top frame 110, which can make the connection strength between the second connecting portion 2131 and the top frame 110 and the auxiliary beam 140 higher, further improving the overall strength of the battery pack bracket.

[0053] In some embodiments, please refer to Figures 1 to 7The assembly frame 300 also includes a second reinforcing beam 311 and an auxiliary inclined beam 312. The second reinforcing beam 311 extends along the second direction Y, with one end connected to the first beam 310 and the other end connected to the bottom frame 100. The second reinforcing beam 311 supports the bottom frame 100. The auxiliary inclined beam 312 is connected at one end to the first beam 310 and at the other end to the bottom frame 100 and the second reinforcing beam 311. Specifically, the assembly frame 300 has second reinforcing beams 311 on both sides in the second direction Y, which are connected to the first beam 310 and the frame body of the bottom frame 100 along the length direction. The second reinforcing beams 311 can support both ends of the bottom frame 100 along the length direction, improving the overall strength of both ends of the battery pack bracket. The auxiliary inclined beam 312 is located between the second reinforcing beams 311 on the same first beam 310. One end of the auxiliary inclined beam 312 is connected to the first beam 310, and the other end is connected to the frame of the bottom frame 100 in the length direction and the second reinforcing beam 311. This can further improve the overall strength of the battery pack bracket, so that the battery pack bracket can provide reliable support for the battery pack 400, high voltage box, charging equipment and water-cooled unit.

[0054] In this embodiment, please refer to further details. Figure 8 A stiffening plate 340 is also provided between the first beam 310, the frame of the bottom frame 100, and the second reinforcing beam 311 to further enhance the supporting effect of the second reinforcing beam 311 on the bottom frame 100. In addition, the second reinforcing beam 311 and the auxiliary inclined beam 312 are welded together by a pad 330.

[0055] In some embodiments, please Figures 1 to 3 Further reference Figure 9 and Figure 10 The assembly frame 300 also includes an assembly component 313, which is connected to the first beam 310. The assembly component 313 has a plate-like structure, and multiple assembly components 313 may be included, in various sizes. Multiple assembly components 313 are mounted on the first beam 310 along a first direction X. The assembly component 313 can be installed on the vehicle using bolts or other fasteners, enabling the assembly of the battery pack bracket with the vehicle.
