[0042] Figures 1 to 3 The battery 10 in some embodiments of the present invention is shown. The battery 10 can be any type of battery in the related art. The battery 10 includes a housing 1, a surrounding mechanism 2, a conducting mechanism 3 and a stabilizing mechanism 4.

[0043] It can be understood that the housing 1 and the surrounding mechanism 2 play a role of storage. The surrounding mechanism 2 also plays a role in fixing the conductive mechanism 3. The conductive mechanism 3 not only plays a role in storing and outputting electric energy, but also plays a role in transmitting electric energy. The stabilizing mechanism 4 plays a role in stabilizing some components of the conductive mechanism 3.

[0044] like Figures 1 to 5 As shown, the enclosure mechanism 2 includes a cover body 21 and a fixing ring 22. The cover body 21 is arranged on the shell 1. The shell 1 and the cover body 21 together enclose a storage space 11. The fixing ring 22 is arranged on the cover body 21. The fixing ring 22 encloses a mounting position 211 on the cover body 21. A connecting hole 212 is opened at the bottom of the mounting position 211.

[0045] It can be understood that the cover 21 is used to accommodate the battery cell 31 together with the housing 1. The fixing ring 22 is used to fix the covering member 41. The mounting position 211 is used to install the fixing ring 22. The connecting hole 212 is used to connect the pole 34 on one side of the cover 21 with the battery cell 31 on the other side of the cover 21.

[0046] It should be noted that the mounting position 211 can be configured to be completely defined by the fixing ring 22 in some embodiments, and can be configured to be defined by the fixing ring 22 and a groove body opened on the cover body 21 in other embodiments, and the groove body also serves to position the fixing ring 22.

[0047] like Figures 1 to 5As shown, the conduction mechanism 3 includes a battery cell 31, a conductive member 32, at least two sealing rings 33 and a pole 34. The battery cell 31 and the conductive member 32 are respectively arranged in the storage space 11. The conductive member 32 is electrically connected to the battery cell 31 and the pole 34 respectively. Each sealing ring 33 and the pole 34 are respectively arranged in the installation position 211. Each sealing ring 33 is placed outside the connecting hole one by one. Each sealing ring 33 is respectively supported on the pole 34 and the bottom of the installation position 211. A convex edge 341 is provided in the circumferential direction of the pole 34, and the fixing ring 22 surrounds the pole 34.

[0048] It can be understood that the battery cell 31 can be configured as a battery cell used in various battery types in the prior art. The conductive member 32 is used to conduct the battery cell 31 with the pole 34 so that current can be transmitted between the battery cell 31 and the pole 34. The sealing ring 33 is used to seal the matching gap between the bottom of the pole 34 and the cover 21. The number of the sealing rings 33 is set to at least two. When a single sealing ring 33 fails, the remaining sealing rings can be used to seal and prevent leakage, thereby improving the leakage-proof reliability of the product. The pole 34 is used to conduct the battery cell 31 with an external power supply or power consumption mechanism.

[0049] It should be noted that if Figure 4 and Figure 5 As shown, the inner diameters of the sealing rings 33 are different, and the sealing rings 33 are configured to be concentrically arranged, so that the sealing rings 33 are installed one by one from the inside to the outside.

[0050] like Figures 1 to 5 As shown, the stabilizing mechanism 4 includes a covering member 41 . The covering member 41 covers the flange 341 . The covering member 41 abuts against the bottom of the pole 34 , the fixing ring 22 and the mounting position 211 , respectively.

[0051] It can be understood that the covering member 41 covers the convex edge 341 from all directions, and since the covering member 41 respectively abuts against the bottom of the pole 34, the fixing ring 22 and the mounting position 211, that is, the covering member 41 will be clamped between the pole 34, the fixing ring 22 and the bottom of the mounting position 211; in this way, when the pole 34 is subjected to pressure toward the cover body 21, the covering member 41 can support the pole 34 from the bottom of the pole 34; when the pole 34 is subjected to a pulling force away from the cover body 21, the covering member 41 can provide limited support from above the convex edge 341; when the pole 34 is subjected to a force parallel to the surface of the cover body 21, the covering member 41 can limit the pole 34 from various circumferential positions, thereby limiting the position of the pole 34 in the circumferential direction.

[0052] In summary, the setting position of the pole 34 in the installation position 211 can be effectively fixed, and the setting stability of the pole 34 can be improved, so that the spacing between the bottom of the pole 34 and the bottom of the installation position 211 can be kept stable, thereby ensuring that the compression amount of the sealing ring 33 is kept as constant as possible, thereby ensuring the sealing effect of the sealing ring 33, and achieving the effect of always sealing the matching gap between the cover body 21 and the pole 34.

[0053] like Figure 4 and Figure 5 As shown, in some embodiments of the battery 10, the stabilizing mechanism 4 also includes a cover member 42, which is disposed on the fixing ring 22, abuts against the pole 34, is connected to the covering member 41, and the cover member 42 and the covering member 41 jointly cover the fixing ring 22.

[0054] It can be understood that the cover member 42 is used to cover the outer side of the fixing ring 22 together with the cover member 41, and the two are also used to fill the matching gap between the pole 34 and the fixing ring 22, so as to improve the position stability of the pole 34 in the fixing ring 22 and prevent the pole 34 from accidentally shifting. The cover member 42 and the covering member 41 can be configured to be connected by common connection methods such as bonding, welding or welding.

[0055] like Figure 4 and Figure 5 As shown, in some embodiments of the battery 10, the cover 42 and the covering 41 are an integral injection-molded structure.

[0056] It can be understood that by simultaneously manufacturing the cover avoidance member 42 and the covering member 41 by injection molding, not only the connection strength between the cover avoidance member 42 and the covering member 41 can be improved, but also the cover avoidance member 42 and the covering member 41 can be fully covered with various positions of the fixing ring 22, and the covering member 41 can be fully covered with various positions of the flange 341, and the gap between the fixing ring 22 and the pole 34 can be fully filled; in this way, the cover avoidance member 42 and the covering member 41 can be more firmly fixed on the fixing ring 22 and the flange 341, and the fitting gap between the pole 34 and the fixing ring 22 can be eliminated as much as possible, thereby significantly improving the position stability of the stabilizing mechanism 4 on the cover body 21, preventing shaking or accidental displacement, and ensuring the sealing effect of the sealing ring 33.

Figure 3 ), a second profiling groove 213 is formed at the bottom of the mounting position 211, and the first profiling groove 342 and the second profiling groove 213 together accommodate the sealing ring 33.

[0058] It can be understood that the bottom surface of the convex edge 341 is flush with the bottom surface of the pole 34. The number of the first profiling grooves 342 can be flexibly set, preferably the number of the first profiling grooves 342 is configured to be equal to the number of the sealing rings 33, and preferably the number of the second profiling grooves 213 is configured to be equal to the number of the first profiling grooves 342.

[0059] It should be noted that the first contoured groove 342 and the second contoured groove 213 are used to clamp the sealing ring 33 from opposite sides respectively, so that the sealing ring 33 is compressed, and the sealing ring 33 can seal the matching gap between the bottom of the sealing pole 34 and the bottom of the installation position 211 to prevent leakage.

[0060] like Figure 4 As shown, in some embodiments of the battery 10, the fixing ring 22 includes an annular wall portion 221, the upper portion of the annular wall portion 221 extends toward the center of the annular wall portion 221 to form an upper transverse portion 222, and the lower portion of the annular wall portion 221 extends toward the direction away from the center of the annular wall portion 221 to form a lower transverse portion 223, the lower transverse portion 223 is connected to the mounting position 211, and the covering member 41 fills the gap between the lower transverse portion 223 and the mounting position 211.

[0061] It can be understood that the annular wall portion 221 is annular as a whole. A rounded corner is provided at the connection position between the lower transverse portion 223 and the annular wall portion 221, and a rounded corner is provided at the connection position between the upper transverse portion 222 and the annular wall portion 221. The provision of the rounded corner can prevent stress concentration and damage at the connection position. The provision of the upper transverse portion 222 can further prevent the stabilizing mechanism 4 from escaping from the fixing ring 22, especially when the pole 34 is subjected to the longitudinal force, the provision of the upper transverse portion 222 can play a certain role in clamping and limiting.

[0062] like Figures 1 to 5 As shown, in some embodiments of the battery 10, the conducting mechanism 3 further includes a connecting portion 331 (the connecting portion 331 is shown in FIG. Figure 8 ), the connecting portion 331 connects the two sealing rings 33 respectively, and the connecting portion 331 and the two sealing rings 33 are an integrally formed structure. It can be understood that the setting of the connecting portion 331 can limit the relative position of the two sealing rings 33, thereby improving the assembly efficiency of the two sealing rings 33 and eliminating the tediousness of manually positioning the two sealing rings 33.

[0063] like Figure 4 and Figure 5 As shown, in some embodiments of the battery 10 , a hook 12 is provided on the housing 1 , and the hook 12 passes through and clamps the connecting hole 212 .

[0064] It can be understood that the hook 12 has a certain degree of deformation ability, and can automatically reset after the hook 12 passes through the connecting hole 212 , so that the hook 12 automatically clamps with the connecting hole 212 .

[0065] like Figure 2 As shown, in some embodiments of the battery 10 , a mounting groove 214 is formed on the cover 21 , and the mounting groove 214 defines a mounting position 211 .
