[0040] The battery liquid injection hole sealing structure 100 according to the embodiments of the present application is described below with reference to the drawings.

[0041] Referring to Figures 1-10 As shown, the sealing structure 100 according to the embodiments of the present application can include a shell 10 and a blocking piece 20.

[0042] Specifically, the shell 10 is provided with a liquid injection hole 11, and the interior of the shell 10 can be injected through the liquid injection hole 11. The liquid injection hole 11 can be arranged at different positions of the shell 10, for example, in some embodiments, the shell 10 includes a top plate, a bottom plate and a side plate, and the liquid injection hole 11 can be arranged on the top plate, the bottom plate or the side plate, and the arrangement position of the liquid injection hole 11 can be flexibly selected.

[0043] The sealing member 20 is arranged in the interior of the shell 10, and is used to open and seal the liquid injection hole 11. The liquid injection hole 11 can be opened by the sealing member 20 to perform operations such as exhausting and supplementing liquid in the interior of the shell 10, and the liquid injection hole 11 can be closed by the sealing member 20 to seal the interior of the shell 10. The sealing member 20 is arranged in the interior of the shell 10, that is, the sealing member 20 is always located in the interior of the shell 10, and the sealing member 20 does not need to be removed from the liquid injection hole 11, which is beneficial to simplify the production process of the battery.

[0044] The sealing member 20 can be modified from a battery original component welded at the liquid injection hole 11 to seal the liquid injection hole 11, so that no new component needs to be added, and temporary sealing materials such as rubber plugs are also saved, which is beneficial to reduce the cost and save the process of inserting and pulling out the rubber plug, and the production efficiency of the battery is higher.

[0045] For example, in some embodiments, as shown in Figure 1 The sealing member 20 can be welded with the shell 10 after pre-charging, and there is a welding mark 200 at the junction of the sealing member 20 and the liquid injection hole 11. The welding method can be laser welding or electric arc welding.

[0046] During the pre-charging process, the battery needs to be restrained, and the battery will be extruded by the outside. In some related technologies, the rubber plug needs to be removed before pre-charging and plugged after pre-charging, that is, there is no sealing structure at the liquid injection hole during the pre-charging process, so that the electrolyte in the battery is easily extruded out during the pre-charging process, causing the battery and the equipment near the battery to be corroded by the electrolyte, and the safety is poor.

[0047] In the present application, the liquid injection hole 11 is opened by the sealing member 20 during the pre-charging process to exhaust, and the liquid injection hole 11 is sealed by the sealing member 20 to seal the battery, for example, the liquid injection hole 11 can be sealed before the electrolyte is extruded out, which reduces the risk of liquid leakage of the battery and has good safety.

[0048] The sealing structure 100 can further include a rod member 30, the rod member 30 is located in the interior of the shell 10 and connected with the shell 10, and the connection between the rod member 30 and the shell 10 can be one or a combination of a plurality of connection modes such as welding, bolt connection, clamping, etc.

[0049] The sealing member 20 is provided with a through hole 21, the rod member 30 is arranged in the through hole 21, and the sealing member 20 is slidable along the rod member 30 in a direction parallel to the center line of the liquid injection hole 11 to open and seal the liquid injection hole 11. In the present application, the liquid injection hole 11 and the through hole 21 can be circular holes, square holes or irregularly shaped holes, etc., and the shapes are various. For the convenience of understanding, the liquid injection hole 11 and the through hole 21 are taken as circular holes in the following explanation.

[0050] The center line of the liquid injection hole 11 can extend along the through direction of the liquid injection hole 11. For example, in some embodiments, as shown in Figures 1-3 the liquid injection hole 11 is a circular hole, the center line of the liquid injection hole 11 extends through the center of the circular hole and along the up-down direction.

[0051] The sealing member 20 is arranged inside the shell 10 through the rod member 30, and the movement of the sealing member 20 for opening and sealing the liquid injection hole 11 can be guided through the rod member 30, so that the sealing member 20 moves along the extension direction of the center line of the liquid injection hole 11 and is not easy to deviate or shake, the operation of the sealing member 20 for opening and sealing the liquid injection hole 11 is more stable, the risk of sealing failure caused by incomplete sealing is reduced, and the production efficiency of the battery is improved.

[0052] According to the sealing structure 100 of the battery liquid injection hole, the sealing member 20 is used to open and seal the liquid injection hole 11, the rubber plug can be omitted, the process of inserting and pulling out the rubber plug is omitted to simplify the production process of the battery, and the sealing member 20 can be guided through the rod member 30, so that the operation of the sealing member 20 for opening and sealing the liquid injection hole 11 is more stable and reliable, and the production efficiency of the battery is improved.

[0053] The sliding of the sealing member 20 along the rod member 30 in the direction parallel to the center line of the liquid injection hole 11 can be controlled through various structures, so that the movement of the sealing member 20 is flexibly controlled.

[0054] For example, in some embodiments, the sealing member 20 is subjected to a pressure from the outside of the shell 10 towards the inside of the shell 10 through the external tool 300, or the sealing member 20 is subjected to a repulsive force from the outside of the shell 10 towards the inside of the shell 10 through the cooperation between the magnetic member on the external tool 300 and the magnetic member on the sealing member 20, and the like, so that the sealing member 20 moves towards the direction away from the liquid injection hole 11 to open the liquid injection hole 11. The sealing member 20 is sucked by the suction cup on the external tool 300 to exert a force from the inside of the shell 10 towards the outside of the shell 10 on the sealing member 20, or the sealing member 20 is hooked by the hook on the external tool 300 to exert a force from the inside of the shell 10 towards the outside of the shell 10 on the sealing member 20, or the sealing member 20 is sucked by the magnetic member on the external tool 300 to exert a suction force from the inside of the shell 10 towards the outside of the shell 10 on the sealing member 20, and the like, so that the sealing member 20 moves towards the direction close to the liquid injection hole 11 to open the liquid injection hole 11.

[0055] In some embodiments of the utility model, as shown in Figures 4-5 the rod member 30 is in clearance fit with the through hole 21, so that the sliding of the sealing member 20 along the rod member 30 in the direction parallel to the center line of the liquid injection hole 11 is not easy to wear or jam, the service life of the rod member 30 and the sealing member 20 is prolonged, and the sliding operation of the sealing member 20 relative to the rod member 30 is more smooth.

[0056] In some embodiments, as shown in Figure 4 and Figure 6 , the through holes 21 are multiple, the rod members 30 are multiple, the multiple rod members 30 are correspondingly arranged in the through holes 21, and the cooperation of the multiple rod members 30 and the multiple through holes 21 makes the sliding of the blocking member 20 along the rod members 30 not easy to be skewed, and the guiding effect on the blocking member 20 is better.

[0057] In some embodiments, as shown in Figure 4 and Figure 6 , the multiple through holes 21 are centrally symmetric about the center line of the liquid injection hole 11, so that the multiple rod members 30 can uniformly apply guiding force to the blocking member 20 about the center line of the liquid injection hole 11, further reducing the possibility of skewing of the blocking member 20 during sliding, and the guiding effect on the blocking member 20 is better.

[0058] In some embodiments of the utility model, as shown in Figure 4 and Figures 6-7 , the distance between the center line of the through hole 21 and the center line of the blocking member 20 is r1, the distance between the center line of the rod member 30 and the center line of the liquid injection hole 11 is r2, and r1=r2. The center line of the through hole 21 can extend in the direction of the through hole 21, and the center line of the rod member 30 can extend in the length direction of the rod member 30. For example, in some embodiments, as shown in Figures 1-4 and Figures 6-7 , the through hole 21 is a circular hole, the through hole 21 penetrates in the up-down direction, the center line of the through hole 21 passes through the center of the circular hole and extends in the up-down direction, the rod member 30 extends in the up-down direction, the cross section of the rod member 30 perpendicular to the up-down direction is circular, and the center line of the rod member 30 passes through the center of the cross section of the rod member 30 and extends in the up-down direction.

[0059] r1=r2 makes the installation of the rod member 30 arranged in the through hole 21 more smooth, so as to more conveniently assemble the blocking member 20 and the rod member 30. It can be understood that r1 and r2 are equal within a certain error, so that r1 and r2 are approximately equal, so as to reduce the manufacturing difficulty of the blocking structure 100.

[0060] In some embodiments, as shown in Figure 7 , in the direction perpendicular to the center line of the liquid injection hole 11, the distance between the center line of the rod member 30 and the center line of the liquid injection hole 11 is r2, the radius of the rod member 30 is r3, the maximum distance between the edge of the liquid injection hole 11 and the center line of the liquid injection hole 11 is r4, r4

[0061] In some embodiments, as shown in Figures 1-4 and Figure 7 , the injection hole 11 is a circular hole, the maximum distance between the edge of the injection hole 11 and the center line of the injection hole 11 is r4, which is the radius of the injection hole 11, and the projection of the injection hole 11 and the rod 30 in the up-down direction does not overlap.

[0062] In some embodiments, as shown in Figure 8 , in the direction perpendicular to the center line of the injection hole 11, the maximum distance between the edge of the injection hole 11 and the center line of the injection hole 11 is r4, the minimum distance between the edge of the sealing member 20 and the center line of the sealing member 20 is r5, and r4 < r5, so that the part of the sealing member 20 in contact with the shell 10 in the state of sealing the injection hole 11 is not easy to be exposed, so as to completely seal the injection hole 11 and better seal the injection hole 11. The area of the sealing member 20 is greater than the area of the injection hole 11 to better seal the injection hole 11, which is beneficial to reduce the risk of liquid leakage at the injection hole 11.

[0063] In some embodiments, as shown in Figures 1-4 and Figures 6-8 , the center line of the injection hole 11 extends in the up-down direction, the injection hole 11 is a circular hole in the horizontal plane, the maximum distance between the edge of the injection hole 11 and the center line of the injection hole 11 is r4, which is the radius of the injection hole 11, and the sealing member 20 is circular, the minimum distance between the edge of the sealing member 20 and the center line of the sealing member 20 is r5, which is the radius of the sealing member 20.

[0064] In some embodiments of the utility model, as shown in Figure 5 and Figures 8-10 , the rod 30 comprises a rod body 31 and a limiting protrusion 32 arranged on the outer circumferential surface of the rod body 31, and the rod body 31 is connected with the shell 10 and penetrates through the through hole 21. The limiting protrusion 32 can be arranged at both ends or the middle part of the rod body 31 along the length direction of the rod body 31, so that the limiting protrusion 32 protrudes from the outer circumferential surface of the rod body 31.

[0065] As shown in Figure 5 , Figures 7-8 , the sealing structure 100 comprises an elastic member 40, the elastic member 40 is sleeved on the rod body 31 and abuts between the sealing member 20 and the limiting protrusion 32, and the elastic member 40 can exert a elastic force on the sealing member 20 towards the injection hole 11. The elastic member 40 can be a spring or other elastic component.

[0066] The limiting convex part 32 protrudes from the outer circumferential surface of the rod body 31, so that the elastic member 40 sleeved on the rod body 31 can abut against the limiting convex part 32. The elastic member 40 and the blocking member 20 can be in abutting pressure or fixed connection, and the elastic member 40 and the limiting convex part 32 can be in abutting pressure or fixed connection, so that the elastic member 40 can abut between the blocking member 20 and the limiting convex part 32.

[0067] The elastic member 40 is limited by the blocking member 20 and the limiting convex part 32, so that the elastic member 40 is always located between the blocking member 20 and the limiting convex part 32, so as to change the distance between the blocking member 20 and the limiting convex part 32 by the elastic deformation of the elastic member 40, and then control the sliding of the blocking member 20 along the rod member 30 in the direction parallel to the center line of the liquid injection hole 11. The cost of controlling the movement of the blocking member 20 by the elastic member 40 is low and easy to realize.

[0068] For example, in some embodiments, as shown in Figure 8 , the blocking member 20 is in a state of blocking the liquid injection hole 11, and the elastic member 40 is in a compressed state. The external tool 300 can be used to apply downward pressure to the blocking member 20, so that the elastic member 40 is further compressed and deformed to open the liquid injection hole 11. The external tool 300 can also be removed, so that the blocking member 20 moves upward along the rod member 30 under the elastic force of the elastic member 40 to block the liquid injection hole 11.

[0069] In some embodiments of the utility model, as shown in Figures 1-4 , Figure 6 and Figure 8 , the blocking structure 100 comprises a sealing member 50, which is arranged on the side of the blocking member 20 close to the liquid injection hole 11 and extends along the circumference of the liquid injection hole 11. In the state that the blocking member 20 blocks the liquid injection hole 11, the sealing member 50 is in sealing contact with the inner surface of the shell 10. The sealing member 50 can be used to seal the connection between the blocking member 20 and the inner surface of the shell 10 around the liquid injection hole 11, so as to better seal the liquid injection hole 11 by sealing the liquid injection hole 11 with the sealing member 50 and the blocking member 20.

[0070] The sealing member 50 can be arranged on the surface of the side of the blocking member 20 close to the liquid injection hole 11, or the surface of the side of the blocking member 20 close to the liquid injection hole 11 can be grooved and the sealing member 50 can be arranged in the groove, so that the sealing member 50 can be in sealing connection with the inner surface of the shell 10 in the state that the blocking member 20 blocks the liquid injection hole 11.

[0071] Of course, the sealing member 50 can also be arranged on the shell 10, so that the inner surface of the shell 10, the sealing member 50 and the side of the blocking member 20 close to the liquid injection hole 11 are in sealing contact to seal the liquid injection hole 11. For example, in some embodiments, the sealing member 50 is arranged on the inner surface of the shell 10, and extends along the circumference of the liquid injection hole 11. In the state that the liquid injection hole 11 is blocked by the blocking member 20, the sealing member 50 is in sealing contact with the side of the blocking member 20 close to the liquid injection hole 11. Through the sealing member 50, the inner surface of the shell 10 around the liquid injection hole 11 and the blocking member 20 are in sealing connection, so that the liquid injection hole 11 is sealed by the sealing member 50 and the shell 10, and the sealing effect of the liquid injection hole 11 is better.

[0072] The sealing member 50 extends along the circumference of the liquid injection hole 11, so that the sealing member 50 extends in a ring shape, such as a circular ring shape, a square ring shape, an irregular ring shape, etc. The material of the sealing member 50 can be silica gel or rubber, etc.

[0073] In some embodiments, as shown in Figs. 4 and Figure 8 in the direction parallel to the center line of the liquid injection hole 11, the projection of the liquid injection hole 11 on the blocking member 20 is located within the projection of the inner circumferential surface of the sealing member 50 on the blocking member 20, so that more areas of the sealing member 50 are in sealing connection with the inner surface of the shell 10 rather than exposed to the liquid injection hole 11, which is beneficial to fully utilize the sealing member 50 to make the sealing effect of the liquid injection hole 11 better.

[0074] For example, in some specific embodiments, as shown in Figs. 5 and Figure 4 and Figure 6 the radius r4 of the liquid injection hole 11, the radius r6 of the inner circumferential surface of the sealing member 50, r4 < r6.

[0075] In some embodiments, as shown in Figs. 6, Figure 4 , Figure 6 and Figure 8 in the direction parallel to the center line of the liquid injection hole 11, the projection of the through hole 21 on the blocking member 20 is located outside the projection of the outer circumferential surface of the sealing member 50 on the blocking member 20, so that the sealing member 50 is less likely to interfere with the through hole 21, so that the rod member 30 can be more smoothly arranged in the through hole 21, and the sliding of the blocking member 20 along the rod member 30 is more smooth.

[0076] For example, in some specific embodiments, as shown in Figs. 7 and Figure 4 and Figure 6 the distance between the edge of the through hole 21 and the center line of the blocking member 20 is r7, the radius of the outer circumferential surface of the sealing member 50 is r8, r7 > r8

[0077] In some embodiments in which the sealing member 50 is arranged on the blocking member 20, as shown in Figs. 8, Figure 4 , Figure 6 and Figure 8As shown, in the vertical direction, the projection of the injection hole 11 on the sealing member 20 is located within the area enclosed by the inner circumferential surface of the sealing member 50, and the projection of the through hole 21 on the sealing member 20 is located outside the area enclosed by the outer circumferential surface of the sealing member 50. This results in a better sealing effect at the injection hole 11, smoother installation of the rod 30 on the sealing member 20, and easier installation of the sealing member 50 on the sealing member 20.

Since the sealing structure 100 according to an embodiment of the present invention has the aforementioned beneficial technical effects, the battery according to an embodiment of the present invention, by opening and sealing the filling hole 11 with the sealing member 20, can eliminate the need for a rubber stopper, thus simplifying the battery production process and eliminating the need for inserting and removing the rubber stopper. Furthermore, the rod 30 can guide the sealing member 20, making the operation of opening and sealing the filling hole 11 with the sealing member 20 more stable and reliable, which is beneficial to improving the battery production efficiency.

[0079] In some embodiments, the battery may further include an electrode assembly and an electrolyte. The housing 10 of the sealing structure 100 is used to contain the electrode assembly and the electrolyte, and the electrolyte is injected into the housing 10 through the injection hole 11. The electrode assembly is the component in the battery where the electrochemical reaction occurs. The electrode assembly includes multiple layers of materials such as cathode plates, anode plates, and separators arranged in a stacked manner. The battery mainly relies on the movement of metal ions between the cathode plates and the anode plates to operate.

The blocking piece 20 is arranged inside the shell 10 and located at the lower side of the liquid injection hole 11, and the sealing piece 50 is arranged at the upper side of the blocking piece 20. The blocking piece 20 is circular and provided with four through holes 21 which are symmetric about the center of the circle, and the four rod pieces 30 are correspondingly arranged in the four through holes 21. The rod piece 30 is located inside the shell 10 and comprises a rod body 31 and a limiting protrusion 32 arranged on the outer circumferential surface of the rod body 31, and the rod body 31 is connected with the shell 10. The elastic piece 40 is sleeved on the rod body 31 and abuts between the blocking piece 20 and the limiting protrusion 32, and the elastic piece 40 is in a compressed state. The blocking piece 20 is slidable along the rod piece 30 in the up-down direction to open and block the liquid injection hole 11, and the elastic piece 40 always applies an upward elastic force to the blocking piece 20.

[0083] In the natural state without applying external force to the blocking structure 100, the blocking piece 20 blocks the liquid injection hole 11 under the elastic force of the elastic piece 40, and the sealing piece 50 is in sealing connection with the inner surface of the shell 10, thereby forming a temporary sealing structure. When it is needed to communicate the inside of the shell 10 with the outside, the blocking piece 20 only needs to be pushed away from the inside to the outside to open the liquid injection hole 11.

[0084] For example Figure 2 As shown in the figure, the blocking piece 20 can be pushed away downward by the external tool 300 such as a liquid injection nozzle, so that the electrolyte can be injected into the inside of the shell 10. For example Figure 3 As shown in the figure, the blocking piece 20 can be pushed away downward by the external tool 300 such as an exhaust nozzle, so that the gas in the inside of the shell 10 can flow out. For example Figure 1 As shown in the figure, after the liquid injection, exhaust and other operations are completed, laser welding can be used at the junction between the blocking piece 20 and the liquid injection hole 11 to realize the sealing welding of the liquid injection hole 11.
