[0032] The following will be described with reference to Figures 1 to 4 The explosion-proof valve carrier assembly and the battery according to some embodiments of the present application.

[0033] Embodiment One

[0034] Referring to Figures 1 to 4 As shown in the drawings, the embodiment of the present application provides an explosion-proof valve bearing assembly, comprising: a bearing body 1 and an explosion-proof valve 2; wherein the explosion-proof valve 2 is installed on the bearing body 1, and the bearing body 1 is formed with a reinforcing rib 11 arranged on the side of the explosion-proof valve 2.

[0035] According to the above-described structure, it is known that the bearing body 1 provided in the present application can be a shell of a battery, which will be described hereinafter as an example, and the reinforcing rib 11 is arranged on the structure of the bearing member on the side of the explosion-proof valve 2, i.e. the shell, thereby strengthening the mechanical strength of the whole area of the explosion-proof valve 2 and effectively resisting deformation, and further ensuring the stability of the explosion-proof valve 2.

[0036] Further, preferably, the reinforcing rib 11 is arranged on the side of the circumference of the explosion-proof valve 2 and is close to the explosion-proof valve 2. Of course, it is not limited to this.

[0037] Further, preferably, the bearing body 1, i.e. the shell, is formed with a mounting through hole in a first predetermined direction b, such as the direction of the wall thickness of the shell, and the explosion-proof valve 2 is mounted in the mounting through hole. Based on the foregoing, preferably, the reinforcing rib 11 is arranged on the surface of the shell perpendicular to the first predetermined direction b.

[0038] It should be noted that the bearing body 1 provided in the present application can also be a cover plate of a battery, and the reinforcing rib 11 is arranged on the side of the explosion-proof valve 2 on the cover plate, thereby playing a role of increasing strength and effectively resisting deformation, and further ensuring the stability of the explosion-proof valve 2.

[0039] In this embodiment, preferably, as shown in Figure 1 and Figure 4 , the reinforcing rib 11 is arranged on the outside of the bearing body 1.

[0040] According to the above-described structure, the reinforcing rib 11 is arranged on the outer surface of the bearing member, thereby avoiding scratching the pole group of the battery and playing a role of protecting the pole group.

[0041] It should be noted that the reinforcing rib 11 is not limited to being arranged on the outer surface of the bearing member, and the reinforcing rib 11 can also be arranged on the inner surface of the bearing member.

[0042] In addition, it should also be noted that the inner surface of the bearing member is the side surface close to the pole group, and the outer surface of the bearing member is the side surface away from the pole group.

[0043] In this embodiment, preferably, as shown in Figure 4 , the height difference between the reinforcing rib 11 and the surface of the bearing body 1 on which the reinforcing rib 11 is formed is h, and 0.1mm≤h≤20mm.

[0044] According to the above-described structure, if the height of the reinforcing rib 11 is too small, the reinforcing rib 11 cannot play a high reinforcing role, and if the height of the reinforcing rib 11 is too large, the reinforcing rib 11 occupies a large space and is prone to interference with other components, which is not conducive to the overall capacity of the battery pack, and the reinforcing rib 11 is difficult to process, and the height difference h between the reinforcing rib 11 and the surface of the load-bearing body 1 in which the reinforcing rib 11 is formed is between 0.1 mm and 20 mm.

[0045] In this embodiment, preferably, as shown in FIG. 1, the number of reinforcing ribs 11 is two, and the reinforcing ribs 11 are arranged on opposite sides of the explosion-proof valve 2. Figure 1

[0046] According to the above-described structure, especially when the explosion-proof valve load-bearing assembly is a shell of a battery, because the explosion-proof valve 2 is installed on the narrow side of the load-bearing member, that is, the shell, the length direction space of the narrow side is fully utilized to arrange the reinforcing ribs 11 on opposite sides of the explosion-proof valve 2, so that both sides have uniform deformation resistance.

[0047] It should be noted that: not only is the reinforcing rib 11 arranged on opposite sides of the explosion-proof valve 2, but the reinforcing rib 11 can also be arranged on only one side of the explosion-proof valve 2, and in addition, the number of reinforcing ribs 11 on each side of the explosion-proof valve 2 is not limited to one, but can be more than one, for example, two, three, or four, and the like. Figure 1

[0048] In addition, when the space around the explosion-proof valve 2 is large enough, a plurality of explosion-proof valves 2 can also be arranged on the entire periphery of the explosion-proof valve 2, so as to ensure the uniformity of the strength of the entire periphery of the explosion-proof valve 2, and thus the entire periphery of the explosion-proof valve 2 has uniform deformation resistance, which can effectively resist deformation in this area, thereby improving the structural stability of the explosion-proof valve 2.

[0049] In this embodiment, preferably, as shown in FIG. 1, the reinforcing rib 11 extends along the width direction of the load-bearing body 1. Figure 1

[0050] According to the above-described structure, the reinforcing rib 11 extends along the width direction of the load-bearing body 1, such as a shell, and fully utilizes the width space of the narrow side to as long as possible, thereby further improving the deformation resistance of this area.

[0051] It should be noted that: the reinforcing rib 11 is not limited to extending along the width direction of the load-bearing body 1 as described above, but the reinforcing rib 11 can also extend along the length direction of the load-bearing body 1, which is selected according to actual needs.

[0052] In this embodiment, preferably, as shown in FIG. 1, the reinforcing rib 11 is in a circular arc shape and is arranged around the periphery of the explosion-proof valve 2. Figure 1 It should be noted that: the reinforcing rib 11 is not limited to extending along the width direction of the load-bearing body 1 as described above, but the reinforcing rib 11 can also extend along the length direction of the load-bearing body 1, which is selected according to actual needs.​​​

[0053] According to the structure described above, the explosion-proof valve 2 is preferably oval in this embodiment, so the reinforcing rib 11 is designed in an arc shape, which is further matched with the arc of the end of the explosion-proof valve 2, so as to maximize the length of the reinforcing rib 11 in a limited space, and further improve the strength. It should be noted that the explosion-proof valve 2 is generally oval or circular as described above, and the reinforcing rib 11 is designed in an arc shape, which can adapt to the explosion-proof valve 2 with the above-mentioned shape.

[0054] Of course, the shape of the reinforcing rib 11 is not limited to this, and it can also be other shapes, such as a straight line, etc.

[0055] In this embodiment, as shown in Figure 1 , the reinforcing rib 11 is arranged at a distance from the explosion-proof valve 2 along the length direction of the shell.

[0056] According to the structure described above, the reinforcing rib 11 is at a certain distance from the explosion-proof valve 2, so as not to affect the installation of the explosion-proof valve 2, which is simple and convenient to operate.

[0057] It should be noted that the reinforcing rib 11 can also be adjacent to the explosion-proof valve 2, which is specifically designed according to actual needs.

[0058] In this embodiment, as shown in Figure 4 , the reinforcing rib 11 is formed on the bearing body 1 by stamping.

[0059] According to the structure described above, the reinforcing rib 11 is directly stamped on the bearing body 1, which is simple and convenient to operate, has high production efficiency and good consistency, and the reinforcing rib 11 and the bearing body 1 are integrated, so the overall strength is high and it is not easy to be damaged.

[0060] It should be noted that the reinforcing rib 11 is not limited to being formed by stamping, and other methods can also be used, for example: the reinforcing rib 11 and the bearing body 1 are independent components, and the two can be connected and fixed together by welding, which is specifically selected according to actual needs.

[0061] In this embodiment, as shown in Figure 4 , the bearing body 1 is formed by stamping to protrude outwardly, and the inner side of the bearing body 1 corresponding to the mounting protrusion part is formed with a mounting groove part, and the mounting protrusion part is formed with a mounting through hole, and the explosion-proof valve 2 is mounted in the mounting through hole and the mounting groove.

[0062] According to the structure described above, the protrusion is formed on one side of the bearing member by stamping, and the groove is formed on the opposite side, so as to provide space for installing the explosion-proof valve 2, and also form a structure similar to the reinforcing rib, which helps to improve the strength.

[0063] It should be noted that: it is not limited to the above structure. Alternatively, the installation protrusion may not be stamped on the load-bearing component. That is, the installation through hole may be directly opened on the flat structure to directly install the explosion-proof valve 2. The specific choice depends on the actual needs.

[0064] In this embodiment, preferably, as follows: Figure 1 As shown, in a plane perpendicular to the first preset direction b, the maximum distance between the reinforcing rib 11 and the explosion-proof valve 2 is a, and a≤200mm. This not only effectively increases the mechanical strength of the explosion-proof valve area but also facilitates the forming of the reinforcing rib 11 without affecting the assembly of the explosion-proof valve 2. Of course, it is not limited to this; a>200mm can also be made.

[0065] In summary, this application provides a load-bearing structure for an explosion-proof valve 2. By providing reinforcing ribs 11 on the load-bearing body 1 around the explosion-proof valve 2, the overall mechanical strength of the explosion-proof valve 2 area is enhanced, and the deformation resistance of the explosion-proof valve 2 is improved. Moreover, the load-bearing structure of this explosion-proof valve 2 can be a battery shell or a battery cover, etc.

[0066] In addition, the reinforcing rib 11 is located on the outside of the load-bearing component, that is, on the side away from the electrode assembly, which can prevent the electrode assembly from being scratched and play a role in protecting the electrode assembly.

[0067] In addition, the reinforcing rib 11 can be formed on the load-bearing component by stamping or connected to the load-bearing body 1 by welding. The operation is simple and convenient, and the process is mature.

[0068] In addition, the reinforcing rib 11 can be extended along the length or width of the load-bearing member according to the actual situation of the area, so as to make full use of the space and maximize the strength and resistance to deformation.

[0069] In addition, reinforcing ribs 11 are provided on at least two opposite sides of the supporting body 1, which helps to improve the overall strength of the left and right sides and has a uniform resistance to deformation.

[0070] Furthermore, the height difference between the reinforcing rib 11 and the surface of the supporting body 1 on which the reinforcing rib 11 is formed is h, and 0.1mm≤h≤20mm. If the height of the reinforcing rib 11 is too small, it will not play a significant reinforcing role. If the height of the reinforcing rib 11 is too large, it will occupy a large space, easily interfere with other components, and be detrimental to the overall capacity improvement of the battery pack. Moreover, it will be difficult to process. Therefore, the height difference h between the reinforcing rib 11 and the surface of the supporting body 1 on which the reinforcing rib 11 is formed is between 0.1mm and 20mm.

[0071] In this embodiment, preferably, as follows: Figure 1As shown, the number of explosion-proof valves 2 is one, of course, not limited to this, the number of explosion-proof valves 2 can also be multiple, for example, two or three, etc.

[0072] Embodiment two

[0073] Embodiment two of the present application also provides a battery comprising the explosion-proof valve bearing assembly described in embodiment one, thus, having all the beneficial technical effects of the explosion-proof valve bearing assembly, the same technical features and beneficial effects will not be repeated.

[0074] It should be noted that the bearing body 1 of the explosion-proof valve bearing assembly can be the shell of the battery, and when the bearing body 1 is the shell of the battery, the shell is a rectangular shell, and the explosion-proof valve 2 is installed on the narrow side of the shell, that is, the side formed by the long side and the wide side, in addition, it should be noted that the shell is not limited to being open at both ends along its length, that is, not only limited to the structure of the shell having four sides, but also other structures can be used, for example, the shell can also be open at only one end, that is, the shell has five sides; The bearing body 1 of the explosion-proof valve bearing assembly can also be the cover plate (not shown in the figure) of the battery, which is selected according to actual needs.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solutions of the embodiments of the present application.
