[0047] Figure 1 and Figure 2 A new type of battery cover 10 in some embodiments of the utility model is shown. The new type of battery cover 10 is used to be installed on the battery, and the new type of battery cover 10 plays a protective role.

[0048] like Figures 1 to 5 As shown, the new battery cover 10 includes a cover body 1, a bracket 2, a pull ring 3, a pole 4 and a sealing ring 5. The bracket 2 is arranged on the cover body 1, the pull ring 3 is arranged on the bracket 2, the pole 4 is arranged on the pull ring 3, and the sealing ring 5 is arranged between the pole 4 and the cover body 1.

[0049] It can be understood that the cover 1 plays a supporting and fixing role, the bracket 2 is used to fix the pull ring 3, and the pull ring 3 is used to fix the pole 4, so that the relative position of the pole 4 and the cover 1 is determined. The sealing ring 5 plays a role of sealing and leakproofing.

[0050] like Figures 1 to 5 As shown, the cover body 1 is provided with a mounting hole 11; the bracket 2 is provided with a through hole 21, the bracket 2 is connected to the lower surface of the cover body 1, and the through hole 21 is aligned with the mounting hole 11; the pull ring 3 is arranged on the bracket 2, the pull ring 3 passes through the through hole 21 and is exposed in the mounting hole 11; the bottom of the pole 4 is inserted and fixed to the top of the pull ring 3, and the pole 4 is exposed in the mounting hole 11; the sealing ring 5 is arranged in the mounting hole 11 (the mounting hole 11 is shown in FIG. Figures 3 to 5 ), the sealing ring 5 is respectively sealed against the pole 4, the pull ring 3, the bracket 2 and the hole wall of the mounting hole 11.

[0051] It can be understood that the opening of the mounting hole 11 provides the required space for the pull ring 3 and the pole 4 to be installed. The opening of the through hole 21 allows the pull ring connected to the lower surface of the bracket 2 to pass through the bracket 2 and be exposed in the mounting hole 11. The bracket 2 and the cover body 1 can be connected by snaps, bolts, welding, interference fit or other connection methods in the relevant technology. Since the pull ring 3 passes through the through hole 21 and is exposed in the mounting hole 11, the pole 4 located in the mounting hole 11 can be fixed. The shape and size specifications of the sealing ring 5 can be flexibly set, and can be adjusted according to the predetermined installation position of the sealing ring 5 to ensure that the sealing ring 5 can ensure effective sealing and leakage prevention at the predetermined installation position to ensure the safety factor of the product.

[0052] It should be noted that the bracket 2 is fixed on the cover body 1, thereby fixing the relative positions of the bracket 2 and the cover body 1; the pull ring 3 is arranged on the bracket 2, fixing the relative positions of the bracket 2 and the pull ring 3; the pole 4 is arranged on the pull ring 3, and the relative positions of the pole 4 and the pull ring 3 are also fixed; in this way, in the subsequent installation steps, no matter whether the subsequently installed parts are formed on the pole or the cover body by injection molding, or are pre-formed and then assembled on the pole or the cover body, the subsequently installed parts are guaranteed in the installation position and the size specifications thereof, preventing the problem of insufficient assembly accuracy or insufficient injection molding accuracy due to the poor position of the pole 4, thereby ensuring the safety factor of the product.

[0053] It should also be noted that the pull ring 3 is respectively connected to the cover body 1 and the pole 4, and the sealing ring 5 is correspondingly placed above the cover body 1, which avoids the connecting piece used to connect the battery cell and the pole from directly contacting the sealing ring 5 during the welding process, thereby preventing the sealing ring from being scalded or deformed by the high-temperature connecting piece during the welding process, thereby ensuring the sealing performance of the sealing ring 5, and then ensuring the anti-leakage function, further improving the safety factor of the product.

[0054] In addition, it should be noted that while the pole 4 is riveted by the pull ring 3, the connection position of the two can also be welded. At the same time, in the process of riveting the pole 4, the pole 4 will compress the sealing ring 5, so that the sealing ring 5 respectively presses against the bottom of the pole 4 and the cover 1, thereby ensuring the sealing effect. In addition, since the pole 4 is accurately and reliably fixed by the pull ring 3, the pole 4 with a stable position can always maintain an even and effective pressure on the sealing ring 5, avoiding excessive or insufficient local pressure that leads to a decrease in sealing.

[0055] Furthermore, the pull ring 3 is configured as a metal ring body.

[0056] It can be understood that the metal ring has higher structural strength and stronger thermal conductivity, which can improve the durability of the product and further avoid the problem of local heat accumulation during the welding process.

[0057] like Figures 3 to 5 As shown, in some embodiments of the new battery cover 10, a positioning boss 12 is provided on the cover body 1, a positioning groove 51 is opened on the sealing ring 5, the positioning boss 12 is inserted into the positioning groove 51, and the positioning boss 12 is supported on the inner wall surface of the positioning groove 51.

[0058] It can be understood that the protrusion of the positioning boss 12 is adapted to the groove depth of the positioning groove 51, and the cross-sectional profile of the positioning boss 12 is also adapted to the cross-sectional profile of the positioning groove 51. In this way, when the positioning boss 12 is correspondingly inserted into the positioning groove 51, the groove wall and the groove bottom of the positioning groove 51 will be tightly held against the outer surface of the positioning boss 12, thereby ensuring the sealing. Among them, the inner wall surface of the positioning groove 51 includes the groove wall and the groove bottom of the positioning groove 51.

[0059] like Figures 3 to 5 As shown, in other embodiments of the new battery cover 10, a mounting groove 13 is further provided on the cover body 1, a mounting hole 11 is provided at the bottom of the mounting groove 13, a positioning boss 12 is provided at the bottom of the mounting groove 13, a positioning groove 51 is provided on the sealing ring 5, and the positioning boss 12 is inserted into the positioning groove 51.

[0060] It can be understood that the installation groove 13 prevents the sealing ring 5 from being directly exposed on the upper surface of the cover 1, thereby protecting the sealing ring 5 to a certain extent. Furthermore, the components subsequently assembled on the pole 4 can also be installed and positioned with the help of the positioning groove 51, thereby improving the assembly accuracy. When the positioning boss 12 is correspondingly inserted into the positioning groove 51, the groove wall and the groove bottom of the positioning groove 51 will be tightly against the outer surface of the positioning boss 12, thereby ensuring the sealing performance.

[0061] It should be noted that if the subsequently assembled parts are set on the pole 4 or the cover 1 by injection molding, the opening of the mounting groove 13 can also increase the contact area between the injection-molded parts and the cover 1, thereby increasing the connection strength and improving the durability of the product.

[0062] like Figure 3 and Figure 5 As shown, in some embodiments of the novel battery cover 10 , the positioning boss 12 is annular, and the inner ring side wall of the positioning boss 12 is aligned with the hole wall of the mounting hole 11 .

[0063] It can be understood that the annular positioning boss 12 can ensure that all directions of the circumference are in contact with the sealing ring 5 for sealing. The inner ring side wall of the positioning boss 12 is aligned with the hole wall of the mounting hole 11, so that the sealing ring 5 can continue to extend to the hole wall of the mounting hole 11 after being arranged on the positioning boss 12, thereby extending the corresponding sealing position of the sealing ring 5, thereby improving the sealing performance of the product.

[0064] like Figure 4 and Figure 5 As shown, in some embodiments of the new battery cover 10, a avoidance groove 22 is opened on the lower surface of the bracket 2; the bottom of the pull ring 3 extends outward to form a connecting skirt 31, and the top of the pull ring 3 extends inward to form a clamping skirt 32, the connecting skirt 31 is arranged in the avoidance groove 22, and the clamping skirt 32 is sleeved and fixed on the bottom of the pole 4.

[0065] It can be understood that the avoidance groove 22 is used to accommodate the connection skirt 31, so as to achieve the purpose of positioning and installing the connection skirt 31, thereby achieving the purpose of positioning the pull ring 3 and the cover body 1 relative to each other. The connection between the connection skirt 31 and the avoidance groove 22 can be bonding, clamping, welding, clamping, screwing or other connection methods in the prior art, and of course, multiple connection methods can be used at the same time. The clamping skirt 32 is used to tightly abut against the pole 4 passing through it, so as to accurately position the pole 4.

[0066] It should be noted that the bottom of the pull ring 3 extending outwards means extending in a direction away from the center of the pull ring 3 , and the top of the pull ring 3 extending inwards means extending in a direction close to the center of the pull ring 3 .

[0067] like Figure 4 and Figure 5 As shown, in some embodiments of the novel battery cover 10 , a clamping boss 41 is provided at the bottom of the pole 4 , a clamping skirt 32 is passed through the clamping boss 41 , and the clamping skirt 32 is supported on the peripheral side wall of the clamping boss 41 .

[0068] It can be understood that the bottom of the pole 4 refers to the surface of the pole 4 facing the bracket 2. The height of the clamping boss 41 can be flexibly set, and it is preferred to be able to stably cooperate with the clamping skirt 32.

[0069] Furthermore, the height of the clamping boss 41 is configured to be equal to the thickness of the clamping skirt 32, so that after the clamping boss 41 is inserted into the clamping skirt 32 from one side, the clamping boss 41 will not pass through the other side of the clamping skirt 32, but will be aligned with the clamping skirt 32. In this way, it is possible to avoid the pole from occupying too much space, and more installation space is left for the connecting piece and other components, thereby improving the overall compactness of the product.

[0070] like Figures 3 to 6 As shown, in some embodiments of the novel battery cover 10 , the novel battery cover 10 further includes an injection molded part 6 , which is sleeved on the peripheral side wall of the pole 4 , and the bottom of the injection molded part 6 is abutted against the cover body 1 .

[0071] It can be understood that the injection molded part 6 is configured as a sleeve-shaped structure that fits tightly along the side walls of the pole 4. Its material is selected from thermoplastic resins with good insulation, chemical corrosion resistance and suitable flexibility, such as polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS) or high-temperature resistant nylon, etc., to ensure long-term stability in complex electrochemical environments.

[0072] It should be noted that a precise snap-fit ​​design can be used to ensure a firm fit with the peripheral side wall of the pole 4, or a special adhesive, ultrasonic welding or other non-destructive connection technology can be used to ensure that it is firmly attached to the pole, while the bottom is flatly fitted to the cover 1 to achieve double sealing.

[0073] The novel battery cover 10 further includes an injection molded part 6 , which is injection molded on the cover and abuts against the peripheral outer side wall of the pole 4 .

[0074] It can be understood that the shape of the injection molded part 6 precisely matches the pole contour, and is molded in one step by a precision mold, ensuring the dimensional accuracy and surface quality. During the production process, the injection molded part 6 is directly molded on the pole 4 and the cover 1 by injection molding technology, without the need for additional fixing measures, which greatly simplifies the assembly process and improves the tightness of fit between components.

[0075] like Figure 5 and Figure 7 As shown, in some embodiments of the novel battery cover 10 , a fixed ridge 42 is provided on the peripheral outer wall of the pole 4 , the injection molded part 6 is covered on the fixed ridge 42 , and the fixed ridge 42 is supported on the sealing ring 5 .

[0076] It can be understood that the provision of the fixed convex edge 42 provides a reliable assembly position for the injection molded part 6 and also increases the matching area between the pole 4 and the injection molded part 6 , thereby increasing the assembly accuracy of the pole 4 and the injection molded part 6 .

[0077] like Figures 4 to 7 As shown, in some embodiments of the new battery cover 10, the new battery cover 10 also includes an alignment component 7, which includes at least one alignment notch 71 and at least one alignment column 72; one of the alignment notch 71 and the alignment column 72 is arranged on the fixed flange 42, and the other of the alignment notch 71 and the alignment column 72 is arranged on the injection molded part 6, and the alignment column 72 is inserted into the alignment notch 71, and the alignment column 72 is supported against the inner wall surface of the alignment notch 71.

[0078] It can be understood that the number of the alignment notches 71 is configured to be equal to the number of the alignment posts 72, and there is a one-to-one correspondence between the two, that is, each alignment post 72 is individually inserted into one alignment notch 71. The tight support between the alignment posts 72 and the inner wall of the alignment notch 71 achieves the purpose of ensuring assembly stability through physical restraint force, avoiding any potential offset or rotation, thereby ensuring that the compression amount of each position of the sealing ring 5 is kept as constant as possible, thereby ensuring the sealing performance of the sealing ring 5, and further improving the safety of the product.

[0079] It should be noted that in the embodiment where the injection molded part 6 is configured to be pre-fabricated and then assembled to the pole 4, the plug-in cooperation between the alignment notch 71 and the alignment column 72 can guide and lock the correct docking position between the fixed flange 42 on the pole 4 and the injection molded part 6, thereby improving the positioning accuracy and efficiency during the assembly process.

[0080] In the embodiment where the injection molded part 6 is configured to be injection molded on the pole 4 and the cover 1, the plug-in cooperation between the alignment notch 71 and the alignment post 72 can also prevent the pole from deflecting or other poor positioning phenomena, thereby ensuring sealing safety.

[0081] The battery of the utility model comprises a shell, a winding core and a novel battery cover plate 10 , wherein the winding core is arranged in the shell, and the cover body 1 is covered on the shell.

[0082] It can be understood that the shell plays the role of accommodating the winding core. After the cover body 1 is covered in the shell, the cover body 1 and the shell can enclose a space for the winding core to be installed. The cover body 1 and the shell are sealed to prevent liquid from leaking.

[0083] The energy storage box of the utility model can be used alone, and multiple energy storage boxes can also be used in combination. In some embodiments, the energy storage box includes a box body and a plurality of batteries, and each battery is arranged in the box body.

[0084] It can be understood that the batteries are arranged in sequence in the box, and the specific arrangement is adjusted according to the actual application requirements. In the present invention, since the safety factor of each battery is improved, the safety factor of the energy storage box is also improved.

On the new type of battery cover, on the one hand, a pull ring is arranged on a bracket and the pull ring is configured to be exposed in a mounting hole, and on the other hand, a pole is configured to penetrate a fixed pull ring, so that the sealing ring is completely isolated from the upper part of the bracket, thereby avoiding direct contact between the connecting piece and the sealing ring when welding below the bracket, and at the same time, the heat energy generated by welding can also be quickly transferred to various positions of the pull ring, and further transferred outside the peripheral edge of the pull ring, avoiding excessive local heat accumulation due to untimely heat conduction, preventing the bracket and the sealing ring from being damaged due to local high temperature, preventing leakage and ensuring the safety factor of the product.

[0087] Furthermore, positioning the pole by the pull ring can prevent the pole from being displaced during subsequent processing, thereby ensuring the accuracy of the dimensions and installation of the parts to be assembled or formed in subsequent steps, thereby avoiding the reduction of local voltage breakdown resistance caused by pole displacement, and further improving the safety factor of the product.
