[0039] like Figure 1-Figure 3 As shown, the utility model provides a battery cell mechanism, including a battery cell assembly and a positioning assembly; the battery cell assembly includes a first battery cell 1 and a second battery cell 2, the positioning assembly forms a first installation space and a second installation space, a partition beam is provided between the first installation space and the second installation space, a receiving groove 301 is formed on the partition beam, the receiving groove 301 is located on the side of the partition beam, and an opening is formed correspondingly; the first battery cell 1 is arranged in the first installation space, and the second battery cell 2 is arranged in the second installation space, and the pole ear at one end of the first battery cell 1 and the pole ear at one end of the second battery cell 2 enter the receiving groove 301 through the opening and are connected to each other.

[0040] Compared with the existing technology, the battery cell mechanism provided by the present invention has the following advantages:

[0041] The battery cell mechanism provided by the present invention can provide a stable installation space for the first battery cell 1 and the second battery cell 2 through the first installation space and the second installation space formed by the positioning component, and since a partition beam is provided between the first installation space and the second installation space in the present application, on the one hand, two installation spaces can be made through the partition beam, so that the positioning component can provide more stable support for the first battery cell 1 and the second battery cell 2. On the other hand, since a receiving groove 301 is formed on the partition beam in the present application, and the receiving groove 301 is located on the side of the partition beam and has an opening correspondingly formed, when the first battery cell 1 and the second battery cell 2 are installed, the pole ear at one end of the first battery cell 1 and the pole ear at one end of the second battery cell 2 can be directly placed from the opening into the receiving groove 301 for welding, thereby improving the assembly efficiency to a certain extent.

[0042] Furthermore, the accommodation groove 301 can also be used to preliminarily position the tabs of the first battery cell 1 and the second battery cell 2, thereby preventing the tabs from moving and causing problems such as loose welding or displacement, thereby ensuring welding quality.

[0043] It should be noted that the above-mentioned receiving groove 301 is formed on the side of the partition beam in this application. Figure 2 Based on the perspective of the , it is located on the bottom side of the partition beam and forms an opening, so that the tab can directly enter the receiving groove 301 for positioning and connection. Figure 2 If the positioning assembly is flipped 180°, the above-mentioned accommodating groove 301 will be formed on the upper side of the partition beam. That is to say, the accommodating groove 301 in this application needs to be located at the edge of the side of the partition beam, so that an opening can be formed to facilitate the placement and connection of the tab.

[0044] Alternatively, as Figure 1 Combine Figure 2 As shown, the battery cell structure provided by the present invention further includes a protective member 5 , which is disposed on the opening and completely covers the tab located in the receiving groove 301 .

[0045] Since the accommodating groove 301 is formed at the edge of the side of the partition beam, by providing a protective member 5 and making the protective member 5 cover the opening and completely cover the pole ear in the accommodating groove 301, on the one hand, it can cooperate with the accommodating groove 301 to form a relatively closed limiting space to limit the pole ear connected in the accommodating groove 301 and prevent the pole ear from falling out. On the other hand, by adding the protective member 5, the contact between the pole ear connected in the accommodating groove 301 and the shell can be isolated, which can not only ensure the safety of the pole ear, but also avoid the risk of leakage.

[0046] Therefore, it can be understood that the protective member 5 in the present application is made of insulating material, so as to fully isolate the contact between the tab and the external shell.

[0047] Alternatively, as Figure 1 Combine Figure 2 As shown, the positioning assembly in the present application includes a first positioning member and a second positioning member, and the first positioning member and the second positioning member both include a docking plate 3; the docking plate 3 of the first positioning member is connected to the docking plate 3 of the second positioning member to form a partition beam, and the docking plate 3 of the first positioning member toward the end of the second positioning member and the docking plate 3 of the second positioning member toward the end of the first positioning member are both formed with docking grooves, and the two docking grooves are connected to form a receiving groove 301.

[0048] In actual application, the above-mentioned partition beam in this application is formed by docking two docking plates 3, and the docking plates 3 in this application are hollow structures with docking grooves formed at the ends. Thus, by docking the two docking grooves, the above-mentioned accommodating groove 301 is formed to achieve positioning and accommodation of the tabs.

[0049] Alternatively, as Figure 1 Combine Figure 2 As shown, the first positioning member and the second positioning member in the present application also include a connecting plate 4. The connecting plate 4 of the first positioning member and the docking plate 3 are arranged perpendicular to each other, and the connecting plate 4 of the second positioning member and the docking plate 3 are arranged perpendicular to each other, forming a T-shaped first positioning member and a second positioning member.

[0050] The connecting plate 4 can support and protect the sides of the first battery cell 1 and the second battery cell 2, thereby ensuring the stability of the long battery cell and avoiding bending and deformation during assembly or use.

[0051] The T-shaped first positioning member and the second positioning member can make the force more uniform and ensure the stability of the overall structure.

[0052] Alternatively, as Figure 2 As shown, the connecting plate 4 in the present application includes a plurality of supporting segments 401 and a plurality of connecting segments 402 . The supporting segments 401 and the connecting segments 402 are alternately arranged, and the width of the supporting segments 401 is greater than the width of the connecting segments 402 .

[0053] By alternately arranging the support segments 401 and the connecting segments 402, on the one hand, the battery cells and the overall connecting plate 4 can be supported by the support segments 401; on the other hand, since the width of the connecting segments 402 is smaller than the width of the supporting segments 401, during use, the gas produced by the battery cells can flow directly through the position of the connecting segments 402. Moreover, since the connecting segments 402 and the supporting segments 401 in the present application are alternately arranged, they can fully cover various positions of the battery cells, so that the gas can be quickly released, thereby improving the safety of the overall battery.

[0054] It should be noted that the lengths of the connecting section 402 and the supporting section 401 in the present application are the same, thereby ensuring uniform force on the entire connecting plate 4 and improving the support stability and exhaust stability of the overall structure.

[0055] Alternatively, as Figure 2 Combine Figure 4 As shown, the battery cell mechanism provided by the present invention also includes a first end plate 6 and a second end plate 7; the first end plate 6 and the second end plate 7 are relatively arranged at both ends of the connecting plate 4, and are connected to the connecting plate 4 to form a rectangular first installation space and a second installation space.

[0056] By providing the first end plate 6 and the second end plate 7 at both ends of the connecting plate 4 , a complete rectangular installation space can be formed, thereby achieving stable support for the first battery cell 1 and the second battery cell 2 .

[0057] It should be additionally explained here that tab through-holes 601 are formed on both the first end plate 6 and the second end plate 7 in the present application, thereby providing a basis for the tabs of the first battery cell 1 and the second battery cell 2 to pass through.

[0058] Alternatively, as Figure 2 Combine Figure 4 As shown, in the present application, a clamping portion 403 is formed at one end of the connecting section 402 located at the end away from the supporting section 401, and a clamping groove portion is formed at the position of the first end plate 6 and the second end plate 7 corresponding to the clamping portion 403. The clamping portion 403 is clamped with the clamping groove portion, so that the first end plate 6 and the second end plate 7 can be detachably connected to the connecting plate 4 of the first positioning member and the connecting plate 4 of the second positioning member.

[0059] By forming the clamping grooves at the ends of the first end plate 6 and the second end plate 7 and corresponding to the clamping portion 403 , the connecting plate 4 can be quickly connected to the first end plate 6 and the second end plate 7 , thereby improving assembly efficiency.

[0060] Preferably, if Figure 4 As shown, the clamping portion 403 in the present application includes a clamping section 4031 and an abutting section 4032. The clamping section 4031 is embedded in the clamping slot, and the abutting section 4032 is perpendicular to the clamping section 4031 and abuts against the side of the first end plate 6 and the second end plate 7 away from the battery cell.

[0061] The abutment section 4032 which is perpendicular to the clamping section 4031 can limit the displacement of the connecting plate 4 in the length direction, that is, when the clamping section 4031 is embedded in the clamping slot, the abutment section 4032 can abut against the side of the first end plate 6 and the second end plate 7 facing away from the battery cell, thereby limiting the position of the connecting plate 4 in the length direction through the abutment section 4032, avoiding the problem of movement and squeezing of the battery cell during installation and use, which affects the safety of the overall battery.

[0062] In addition, if Figure 5 Combine Figure 6 As shown, the utility model also provides a battery, including an insulating film 8, a shell, an explosion-proof valve 9 and the above-mentioned battery cell mechanism, the insulating film 8 is coated on the outside of the battery cell mechanism, the insulating film 8 is formed with a first slit portion 801 at a position corresponding to the connecting plate 4, and the insulating film 8 is formed with a second slit portion 802 at a position corresponding to the partition beam; the battery cell mechanism coated with the insulating film 8 is arranged in the shell, the shell is formed with a first accommodating portion at a position corresponding to the first slit portion 801, and a second accommodating portion at a position corresponding to the second slit portion 802, and the explosion-proof valve 9 is correspondingly arranged in the first accommodating portion and the second accommodating portion.

[0063] Batteries using the cell structure provided by this application, on the one hand, have longer and larger cell structures, and on the other hand, can ensure good structural strength, avoiding bending and deformation that can reduce battery yield. Furthermore, the reduced assembly difficulty and improved efficiency of the cell structure can improve both the difficulty and efficiency of battery production.

[0064] In addition, the battery provided in the present application also includes an insulating film 8, and the insulating film 8 has a first slit portion 801 formed at a position corresponding to the connecting plate 4, and a second slit portion 802 formed at a position corresponding to the partition beam, so that the internal gas can pass through the first slit portion 801 and the second slit portion 802. Accordingly, a first accommodating portion formed at a position corresponding to the first slit portion 801 of the shell and a second accommodating portion formed at a position corresponding to the second slit portion 802 can provide an installation basis for the explosion-proof valve 9, so that the internal gas can be quickly discharged from the explosion-proof valve 9 through the first slit portion 801 and the second slit portion 802, thereby ensuring the safety of the entire battery.

[0065] It should be noted that the battery provided in the present application further includes a cover plate 10, and the cover plates 10 are relatively arranged at both ends of the shell and cover the opening of the shell, thereby forming a closed accommodation space to accommodate the above-mentioned battery cell mechanism.

[0066] Since the end of the connecting plate 4 in this application is formed with a snap-fit ​​portion 403, the corresponding position of the cover plate 10 is eliminated from the design of other structures, thereby avoiding interference and affecting assembly. Furthermore, since the explosion-proof valve 9 in this application is located on the narrow side and large side surface of the housing, the explosion-proof valve 9 is not required to be provided on the cover plate 10, thereby saving manufacturing process and cost.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
