[0032] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0033] Below, refer to the attached Figures 1-8 Describe the top cover assembly 100 according to the embodiment of the present utility model.

[0034] Refer to Figure 1 , Figure 2 And Figure 5 , the top cover assembly 100 according to the embodiment of the present utility model includes: a top cover body 10 and an explosion-proof valve 20.

[0035] Specifically, an explosion-proof valve hole 11 is provided on the top cover body 10, and a reinforcing rib 12 is provided at a circumferential position of the top cover body 10 near the explosion-proof valve hole 11. The reinforcing rib 12 is arranged along the circumference of the explosion-proof valve hole 11; the explosion-proof valve 20 seals the explosion-proof valve hole 11.

[0036] For example, as shown in Figure 1 , Figure 2 And Figure 5 , an explosion-proof valve hole 11 penetrating the top cover body 10 in the thickness direction of the top cover body 10 is provided on the top cover body 10, and a reinforcing rib 12 is provided on the top cover body 10 at a position near the circumference of the explosion-proof valve hole 11.

[0037] The top cover assembly 100 of the present utility model is provided with a reinforcing rib 12 near the explosion-proof valve hole 11, which can strengthen the strength of the top cover body 10 at the position of the explosion-proof valve hole 11, thereby effectively preventing the top cover body 10 from being damaged, improving the service life of the top cover body 10. At the same time, the strength of the position of the explosion-proof valve 20 port on the top cover body 10 is ensured, so that the connection reliability between the explosion-proof valve 20 and the top cover body 10 can be guaranteed, and further the risk of the explosion-proof valve 20 failing can be reduced, and the use safety of the battery 1000 can be improved. Moreover, the reinforcing rib 12 is arranged on the top cover body 10. Compared with the prior art solution of arranging the reinforcing rib 12 along the periphery of the explosion-proof valve hole 11, the top cover assembly 100 of the present application does not affect the installation of the explosion-proof valve 20, thereby reducing the installation difficulty of the explosion-proof valve 20. In addition, the processing difficulty of the top cover body 10 can be reduced, the processing time can be saved, and further the production efficiency can be improved.

[0038] For the top cover assembly 100 according to an embodiment of the present utility model, a reinforcing rib 12 is arranged near the explosion-proof valve hole 11, which can strengthen the strength of the top cover body 10 at the position of the explosion-proof valve hole 11, thereby effectively preventing the top cover body 10 from being damaged, improving the service life of the top cover body 10. At the same time, the risk of the explosion-proof valve 20 failing can also be reduced, and the use safety of the battery 1000 can be improved.

[0039] According to some embodiments of the present utility model, with reference to Figure 6 and Figure 7 , the reinforcing rib 12 is formed by being recessed downward along the thickness direction of the top cover body 10 (such as the front-back direction of the top cover body 10 shown in Figure 6 ). Thus, this setting form can not only play a role in strengthening the strength of the periphery of the explosion-proof valve hole 11, but also does not occupy the space inside the battery 1000, and further the rationality of the setting form can be ensured. For example, as shown in Figure 6 and Figure 7 , the reinforcing rib 12 is formed by being recessed backward from the surface of the top cover body 10.

[0040] According to some alternative embodiments of the present utility model, with reference to Figure 6 and Figure 7 , the depth of the downward recess of the reinforcing rib 12 is 0.1 mm - 0.5 mm. Thus, by limiting the degree of the recess of the reinforcing rib 12, the effect of the reinforcing rib 12 in strengthening the explosion-proof valve hole 11 can be ensured, and at the same time, the situation that the depth of the reinforcing rib 12 is too deep and occupies the space inside the battery 1000 can be avoided.

[0041] For example, as shown in Figure 6 and Figure 7 , the depth of the downward recess of the reinforcing rib 12 can be: 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm or 0.5 mm.

[0042] According to some embodiments of the present utility model, with reference toFigure 5 and Figure 6 The reinforcing rib 12 is provided on opposite sides of the explosion-proof valve hole 11, and the reinforcing rib 12 extends along the width direction of the explosion-proof valve hole 11. Thus, it can be ensured that both opposite sides of the explosion-proof valve hole 11 are strengthened, thereby effectively preventing damage to the periphery of the explosion-proof valve hole 11 of the top cover body 10.

[0043] For example, as shown in Figure 5 and 6 , the reinforcing rib 12 is provided on the upper and lower sides of the explosion-proof valve hole 11, and the reinforcing rib 12 extends linearly in the left-right direction.

[0044] According to some alternative embodiments of the present invention, referring to Figure 5 and Figure 6 , the width w of the reinforcing rib 12 is 0.5 mm - 5 mm. Thus, by defining the width of the reinforcing rib 12, the strength of the reinforcing rib 12 can be ensured, thereby ensuring the effect of the reinforcing rib 12 strengthening the periphery of the explosion-proof valve hole 11. At the same time, it can also avoid the problem that the too wide width of the reinforcing rib 12 affects the layout space of other structures on the top cover body 10.

[0045] For example, as shown in Figure 5 , the width of the reinforcing rib 12 can be: 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm or 5 mm.

[0046] According to some embodiments of the present invention, referring to Figure 5 and Figure 6 , the distance d between the reinforcing rib 12 and the periphery of the explosion-proof valve hole 11 is 1 mm - 10 mm. Thus, it can prevent the distance between the reinforcing rib 12 and the periphery of the explosion-proof valve hole 11 from being too long, which affects the effect of the reinforcing rib 12 strengthening the strength of the explosion-proof valve hole 11. At the same time, it can also prevent the distance between the reinforcing rib 12 and the periphery of the explosion-proof valve hole 11 from being too short, which affects the installation of the explosion-proof valve 20.

[0047] For example, as shown in Figure 5 , the distance between the reinforcing rib 12 and the periphery of the explosion-proof valve hole 11 can be: 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm.

[0048] According to some embodiments of the present invention, referring to Figure 8 , the number of the reinforcing ribs 12 is multiple, that is to say, the number of the reinforcing ribs 12 can be two, three or four or more, and multiple reinforcing ribs 12 are arranged at intervals around the periphery of the explosion-proof valve hole 11. Thus, multiple reinforcing ribs 12 can ensure the effect of the reinforcing ribs 12 strengthening the periphery of the explosion-proof valve hole 11, thereby effectively preventing damage at the explosion-proof valve hole 11 of the top cover body 10.

[0049] For example, as shown inFigure 8 As shown, four reinforcing ribs 12 are provided on the top cover body 10 near the periphery of the explosion-proof valve hole 11. Two of the reinforcing ribs 12 are provided on the upper and lower sides of the periphery of the explosion-proof valve hole 11, and the other two reinforcing ribs 12 are provided on the left and right sides of the periphery of the explosion-proof valve hole 11.

[0050] According to some embodiments of the present invention, with reference to Figure 2 and Figure 4 , the top cover body 10 is a stamping part, and the reinforcing ribs 12 are formed by stamping. Thus, the top cover body 10 with this structure can not only ensure the strength of the top cover body 10, but also ensure the processing efficiency of the top cover body 10. At the same time, by using the same process, the reinforcing ribs 12 can be directly processed, which can effectively improve the production efficiency.

[0051] According to some embodiments of the present invention, with reference to Figure 2 and 5 , two pole holes 13 are provided on the top cover body 10, and the two pole holes 13 are arranged at intervals along the extending direction of the top cover body 10. Thus, the pole holes 13 can facilitate the pole to extend out of the top cover body 10, so as to facilitate the connection of the pole with other structures.

[0052] For example, as Figure 2 and Figure 5 shown, the top cover body 10 is a rectangular plate extending in the up and down direction, and the pole holes 13 are provided on the upper side of the explosion-proof valve hole 11, and the two pole holes 13 are arranged at intervals in the up and down direction.

[0053] According to the battery 1000 of the second aspect embodiment of the present invention, with reference to Figure 1 , it includes the top cover assembly 100 of the first aspect of this embodiment.

[0054] According to the battery 1000 of the embodiment of the present invention, by providing the top cover assembly 100 of the first aspect embodiment above, and arranging the reinforcing ribs 12 at a position close to the explosion-proof valve hole 11, the strength of the top cover body 10 at the position of the explosion-proof valve hole 11 can be strengthened, so as to effectively prevent the top cover body 10 from being damaged. At the same time, the risk of failure of the explosion-proof valve 20 can also be reduced, and the use safety of the battery 1000 can be improved.

[0055] Furthermore, as Figure 1 and Figure 2 shown, the battery 1000 includes: a housing 200, an open opening is formed in the front side of the housing 200, and the top cover body 10 covers the open opening. Thus, the battery 1000 can form a sealed whole, so as to ensure the normal function of the battery 1000.
