[0002] A car's battery box typically includes an upper cover, battery modules, a lower housing, and a crossbeam. The battery modules are vertically hoisted into the lower housing. The crossbeam is connected to the lower housing via brackets and can divide the lower housing into multiple chambers, facilitating the isolation of individual battery cells within the battery modules.

[0003] In the existing technology, the connection strength between the crossbeam and the bracket is poor, and the connection is prone to failure after long-term use, resulting in poor overall strength of the battery box and affecting its service life. Utility Model Content

[0004] Therefore, it is necessary to provide a battery box reinforcement structure, a battery box, and an automobile that improves the connection strength between the crossbeam and the bracket.

[0006] The support includes a first support and a second support, which are respectively disposed on both sides of the crossbeam and are used to connect the box body and the crossbeam;

[0007] A first connecting part is provided on the first bracket and is used to connect with the crossbeam;

[0008] A second connecting part is provided on the second bracket and is used to connect with the crossbeam; the first connecting part and the second connecting part enclose an installation area, and the end of the crossbeam is located within the installation area;

[0009] A connecting component includes a connector and a connecting cap. The connector is located in the mounting area and connects the first connecting portion and the second connecting portion to the crossbeam respectively. The connecting cap is connected to the connector and has welding protrusions on it. The welding protrusions are fixedly connected to the first connecting portion / second connecting portion.

[0010] In one embodiment, the connecting components are configured as multiple groups, and the multiple groups of connecting components are distributed at intervals along the height direction of the bracket.

[0011] In one embodiment, one end of the connector abuts against the first connecting portion, and the other end passes through the first connecting portion, the crossbeam, and the second connecting portion in sequence and is connected to the connecting cap; the welding protrusion is fixedly connected to the second connecting portion.

[0012] In one embodiment, the connecting cap and the connecting member are screwed together, and the welding protrusion and the second connecting part are welded together.

[0013] In one embodiment, the welding bumps are provided in multiple locations, and the multiple welding bumps are spaced apart on the side of the connecting cap near the second connecting portion.

[0014] In one embodiment, the first bracket has a first extension and a second extension for connecting to the housing; the first extension is located at the lower part of the first bracket along the height direction of the bracket; the second extension is located at the side of the first connecting part along the length direction of the crossbeam; the second bracket has a third extension and a fourth extension for connecting to the housing; the third extension is located at the lower part of the second bracket along the height direction of the bracket; the fourth extension is located at the side of the second connecting part along the length direction of the crossbeam.

[0031] Please see Figures 1 to 4 This application provides a battery box reinforcement structure. The battery box includes a box body 100 and a crossbeam 200 disposed on the box body 100. The battery box reinforcement structure includes a bracket 1, a first connecting portion 21, a second connecting portion 22, and a connecting component 3. Specifically, the bracket 1 includes a first bracket 11 and a second bracket 12. The first bracket 11 and the second bracket 12 are respectively disposed on both sides of the crossbeam 200 for connecting the box body 100 and the crossbeam 200. The first connecting portion 21 is disposed on the first bracket 11 for connecting to the crossbeam 200. The second connecting portion 22 is disposed on the second bracket 12 for connecting to the crossbeam 200. The first connecting portion 21 and the second connecting portion 22 enclose a mounting area 23, and the end of the crossbeam 200 is located within the mounting area 23. The connecting component 3 includes a connector 31 and a connector cap 32. The connector 31 is located in the mounting area 23 and connects the first connecting portion 21 and the second connecting portion 22 to the crossbeam 200 respectively. The connecting cap 32 is connected to the connecting part 31. The connecting cap 32 is provided with welding protrusions 33, which are fixedly connected to the first connecting part 21 / the second connecting part 22.

[0032] Understandably, the first bracket 11 and the second bracket 12 are respectively located on both sides of the crossbeam 200 and connected to the crossbeam 200 via connectors 31, increasing the number of connection points between the bracket 1 and the crossbeam 200 and thus increasing the connection strength. Secondly, the connecting cap 32 is fixed to the connecting part via welding protrusions 33, fixing the position of the connecting cap 32. This prevents the connecting cap 32 and connector 31 from separating and causing connection failure, making the connection between the bracket 1 and the crossbeam 200 more robust, further improving the connection strength, ensuring the overall strength of the battery box, and extending the battery box's service life.

[0033] Furthermore, the connecting components 3 are configured in multiple groups. Along the height direction of the bracket 1, the multiple groups of connecting components 3 are distributed at intervals.

[0034] Understandably, multiple sets of connecting components 3 can increase the number of connection points between the crossbeam 200 and the bracket 1, further increasing the connection strength between the two. The number of connecting components 3 can be selected according to actual needs and is not specifically limited.

[0035] In one embodiment, one end of the connector 31 abuts against the first connecting portion 21, and the other end passes sequentially through the first connecting portion 21, the crossbeam 200, and the second connecting portion 22 and is connected to the connecting cap 32. The welding protrusion 33 is fixedly connected to the second connecting portion 22.

[0036] In this structure, the connector 31 passes through the crossbeam 200 and the bracket 1. The connector 31 will bear most of the tensile force, which will greatly improve the connection strength and avoid connection failure.

[0037] For example, the connecting cap 32 and the connecting piece 31 are fixedly connected by screws, and the welding protrusion 33 and the second connecting part 22 are fixedly connected by welding. The screw connection has a better locking effect and a more secure connection.

[0038] For example, the connector 31 is a bolt, the connector cap 32 is a nut, and the welding protrusion 33 is a protrusion integrally formed on the nut.

[0039] Furthermore, multiple welding bumps 33 are provided. The multiple welding bumps 33 are distributed at intervals on the side of the connecting cap 32 near the second connecting portion 22.

[0040] Understandably, multiple welding protrusions 33 can increase the connection area between the connecting cap 32 and the second connecting part 22, enhance the connection strength between the two, increase the tensile strength, and improve the strength of the battery box.

[0041] For example, multiple welding protrusions 33 are spaced apart circumferentially along the screw holes on the connector cap 32. This results in a more uniform connection and stress distribution. Four welding protrusions 33 are preferably provided, but the number can be selected according to actual needs.

[0042] In one embodiment, the first bracket 11 is provided with a first extension 111 and a second extension 112 for connecting the housing 100. The first extension 111 is located at the lower part of the first bracket 11 along the height direction of the bracket 1. The second extension 112 is located on the side of the first connecting part 21 along the length direction of the crossbeam 200.

[0043] In one embodiment, the second bracket 12 is provided with a third extension 121 and a fourth extension 122 for connecting the housing 100. The third extension 121 is located at the lower part of the second bracket 12 along the height direction of the bracket 1. The fourth extension 122 is located on the side of the second connecting part 22 along the length direction of the crossbeam 200.

[0044] Understandably, the first extension 111 and the third extension 121 are located at the bottom and can be connected to the bottom surface of the housing 100. The second extension 112 and the fourth extension 122 are located on the side and can be connected to the side wall of the housing 100. The bracket 1 has multiple connection points with the housing 100, ensuring stable connection and improving the overall strength of the battery box.

[0045] Furthermore, the second extension 112 is provided with a first reinforcing section 113, which extends from the second extension 112 toward the first connecting section 21 and abuts against the first connecting section 21.

[0046] Furthermore, the fourth extension 122 is provided with a second reinforcing section 123, which extends from the fourth extension 122 toward the second connecting section 22 and abuts against the second connecting section 22.

[0047] Understandably, in this structure, the first reinforcing section 113, the second extension 112, and the first connecting section 21 form a triangle, as do the second reinforcing section 123, the fourth extension 122, and the second connecting section 22. This structure provides high overall stability and allows the support to withstand greater pressure, reducing the possibility of deformation of the support 1. This avoids the possibility of deformation and failure at the connection between the connector 31 and the support 1, further enhancing the connection strength.

[0048] In one embodiment, the bracket 1 further includes a third bracket 13. The third bracket 13 is disposed on the side of the second extension 112 and the fourth extension 122, and is connected to the second extension 112 and the fourth extension 122, respectively.

[0049] Understandably, the third bracket 13 can connect the second extension 112 and the fourth extension 122, that is, connect the first bracket 11 and the second bracket 12, further improving the overall strength of the bracket 1 and the overall strength of the battery box.

[0050] The connections mentioned above can be made by screwing, riveting, welding, etc. The specific method can be selected according to actual needs, and will not be elaborated here.

[0051] This application also provides a battery case, including the battery case reinforcement structure of any of the above embodiments.

[0052] This application also provides a vehicle including a battery pack reinforcement structure according to any of the above embodiments.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
