[0044] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] like Figures 1-11 As shown, this utility model provides an electrode tab support 3. The electrode tab support 3 is provided with a first support surface 321 and a support groove 322. When the electrode tab support 3 is sandwiched between the core 1 and the electrode plate 2, the first support surface 321 is located at the end of the electrode tab support 3 away from the core 1 and abuts against the electrode plate 2. The electrode tab of the core 1 is sandwiched between the bottom of the support groove 322 and the electrode plate 2.

[0046] In this invention, a tab support 3 is provided between the core 1 and the electrode plate 2. The tab support 3 abuts against the core 1, and the electrode plate 2 is supported by the first support surface 321 on the tab support 3. The tab of the core 1 is accommodated and supported by the support groove 322 recessed on the first support surface 321. Thus, the electrode plate 2 can be reliably supported and fixed on the basis of abutting the tab, ensuring the position and orientation of the electrode plate 2, and improving the efficiency and quality of the assembly of the core assembly and the cover plate assembly 100.

[0047] Specifically, the tab support 3 includes a bottom support plate 31 and a support platform 32 connected to each other. The bottom support plate 31 abuts against the core 1, and the support platform 32 protrudes from one side of the bottom support plate 31. A first support surface 321 is disposed at the end of the support platform 32 opposite to the bottom support plate 31. By setting the bottom support plate 31 to contact the core 1, the bottom support plate 31 supports the support platform 32, thus preventing the support platform 32 from damaging the core 1.

[0048] More specifically, there are two bottom support plates 31, which are spaced apart in the first direction, and the support groove 322 is arranged through the second direction, with the first and second directions forming an angle. This arrangement can save material for the electrode bracket 3 while ensuring that the bottom support plates 31 reliably support the support platform 32.

[0049] In this embodiment, the first direction is perpendicular to the second direction, and the support platform 32 is mounted on one end of the two bottom support plates 31 facing each other.

[0050] Specifically, the end of the support platform 32 facing the core 1 is provided with a relief groove 323. The above-mentioned arrangement further saves the material used for the tab bracket 3 and avoids damaging the core 1.

[0051] like Figure 10 As shown, more specifically, a reinforcing rib 324 is provided in the clearance groove 323. The above-mentioned arrangement ensures the structural strength of the support platform 32.

[0052] In this embodiment, the reinforcing rib 324 includes transverse ribs and longitudinal ribs. The transverse ribs extend along the first direction and are located on the symmetrical plane of the support platform 32. The longitudinal ribs extend along the second direction and are provided in multiples, arranged on both sides of the transverse ribs. The reinforcing rib 324 does not protrude from the groove of the relief groove 323, thereby avoiding damage to the core 1.

[0053] like Figure 5 and Figure 6 As shown, this embodiment also provides a core assembly, including a core 1, an electrode plate 2 and the aforementioned tab support 3. The tab support 3 abuts against the core 1, the first support surface 321 abuts against the electrode plate 2, and the tabs of the core 1 are sandwiched between the bottom of the support groove 322 and the electrode plate 2.

[0054] In the core assembly of this utility model, an electrode tab support 3 is provided between the core 1 and the electrode plate 2. The electrode tab support 3 abuts against the core 1, and the electrode plate 2 is supported by the first support surface 321 on the electrode tab support 3. The electrode tab of the core 1 is accommodated and supported by the support groove 322 recessed on the first support surface 321. Thus, the electrode plate 2 can be reliably supported and fixed on the basis of abutting the electrode tab, ensuring the position and orientation of the electrode plate 2, and improving the efficiency and quality of assembling the core assembly and the cover plate assembly 100.

[0055] Specifically, the core assembly also includes a core support 4, which has a positioning through hole 41. The core support 4 abuts against the core 1, and the support platform 32 passes through the positioning through hole 41. By setting the core support 4, the tab support 3 can be positioned and installed more safely and reliably.

[0056] More specifically, the core support 4 has a first receiving groove 42 on the side facing the core 1, and the bottom support plate 31 is received in the first receiving groove 42. The above arrangement avoids the core support 4 from pressing against the bottom support plate 31 after it is assembled on the core 1, which would cause the bottom support plate 31 to damage the core 1.

[0057] More specifically, the core support 4 has a second receiving groove 43 on the side facing the core 1, and the electrode tab is received in the second receiving groove 43 and the support groove 322. By providing the second receiving groove 43, a passage is provided for the electrode tab on the core 1, so that the electrode tab can pass through the second receiving groove 43 and extend into the support groove 322.

[0058] More specifically, the support groove 322 is provided through the second direction, and in the second direction, the inner walls of the support platform 32 and the positioning through hole 41 are spaced apart. The above arrangement provides a passage for the tabs on the core 1, allowing the tabs to pass through the gap between the support platform 32 and the positioning through hole 41 and extend into the support groove 322.

[0059] In this embodiment, the first receiving groove 42 extends along the first direction and connects to the opening at one end of the positioning through hole 41. Two first receiving grooves 42 are configured for each positioning through hole 41, and the two first receiving grooves 42 are located at both ends of the positioning through hole 41 in the first direction. The second receiving groove 43 extends along the second direction and connects to the opening at one end of the positioning through hole 41. Two second receiving grooves 43 are configured for each positioning through hole 41, and the two second receiving grooves 43 are located at both ends of the positioning through hole 41 in the second direction.

[0060] Specifically, a retaining edge 44 is provided on the side of the core support 4 away from the core 1, and the retaining edge 44 is arranged around the outer periphery of the positioning through hole 41. By providing the retaining edge 44, the tabs on the support platform 32 can be insulated and protected.

[0061] In this embodiment, the core support 4 is provided with two positioning through holes 41, and a retaining edge 44 is configured for each positioning through hole 41. The two retaining edges 44 are respectively arranged around the outer periphery of the two support platforms 32.

[0062] Specifically, of the base support plate 31 and the core support 4, one is provided with a locking head 311 and the other with a locking slot 45, with the locking head 311 being engaged with the locking slot 45. This arrangement allows the tab support 3 to be connected to the core support 4 more stably and reliably.

[0063] In this embodiment, two clips 311 are respectively provided on the two bottom support plates 31 of the tab bracket 3, and a slot 45 is provided at the bottom of the first receiving groove 42 of the core bracket 4 for each clip 311.

[0064] In this embodiment of the core assembly, the bottom surface of the support groove 322 is the second support surface, the surface of the bottom support plate 31 facing the core 1 is the third support surface, the reinforcing rib 324 is disposed on the back of the second support surface, and the clamping head 311 is disposed on the back of the third support surface. During assembly, the tabs of the core 1 surround the second support surface, clamping the second support surface in the middle. The core bracket 4 is provided with a positioning through hole 41, and an upwardly turned-up baffle 44 is provided around the positioning through hole 41. When the core bracket 4 is assembled with the tab bracket 3, the first support surface 321 and the second support surface of the tab bracket 3 will pass through the positioning through hole 41. The core bracket 4 is provided with a first receiving groove 42 at the corresponding third support surface of the tab bracket 3. The bottom of the first receiving groove 42 is provided with a clamping slot 45 to facilitate positioning, assembly and fixation with the tab bracket 3. To ensure that the tab bracket 3 does not protrude from the bottom surface of the core bracket 4 after assembly, and to prevent the plastic protrusion on the tab bracket 3 from damaging the core 1, after the tab bracket 3 is assembled into the core bracket 4, a long slot is formed between its long side and the positioning through hole 41 of the core bracket 4 to accommodate the tab. Since the tab protrudes from the end face of the core 1, a second receiving groove 43 is provided in the area corresponding to the tab protrusion of the core bracket 4 to prevent the tab from being damaged when the core bracket 4 is pressed down. After the tab bracket 3 is assembled in the core assembly, the bottom support plate 31 of the tab bracket 3 abuts against the top end face of the core 1, and the first support surface 321 abuts against the electrode plate 2. Through the above assembly relationship, the effective support of the electrode plate 2 in the height direction can be ensured. An assembly gap is formed between the second support surface and the bottom surface of the electrode plate 2 to accommodate the folded tab.

[0065] like Figures 1-4 As shown, this embodiment also provides a battery, including a cover plate assembly 100 and the above-mentioned winding core assembly, with the electrode plate 2 passing through the electrode post hole of the cover plate assembly 100.

[0066] In the battery of this embodiment, a tab support 3 is provided between the core 1 and the electrode plate 2. The tab support 3 abuts against the core 1, and the electrode plate 2 is supported by the first support surface 321 on the tab support 3. The tab of the core 1 is accommodated and supported by the support groove 322 recessed on the first support surface 321. Thus, the electrode plate 2 can be reliably supported and fixed on the basis of abutting the tab, ensuring the position and orientation of the electrode plate 2, and improving the efficiency and quality of the assembly of the core assembly and the cover assembly 100.

[0067] Specifically, the battery consists of three main parts: a cover plate assembly 100, a core assembly, and a housing 200. The cover plate assembly 100 is provided with terminals, and the terminals are provided with terminal holes. During assembly, the electrode plates 2 on the core assembly pass through the terminal holes on the cover plate assembly 100 and fit into the terminal holes, and then are welded and sealed. The housing 200 is fitted onto the outside of the core assembly, and the cover plate assembly 100 and the housing 200 are fitted together and then welded and sealed.

[0068] More specifically, the core assembly comprises several parts, including a core 1, electrode plates 2, electrode tab supports 3, core supports 4, and an insulating film 5. The two electrode plates 2 are the positive and negative electrode plates, respectively, and the two electrode tab supports 3 are the positive and negative electrode tab supports, respectively. During assembly, the core 1 is first fitted with positive and negative electrode tabs, which are welded to the positive and negative electrode plates respectively. The electrode tab supports 3 are sandwiched between the core 1 and the electrode tabs, abutting against the top face of the core 1 and the bottom face of the electrode plate 2 in the height direction, providing support. After assembling the above semi-finished products, the core supports 4 are assembled on top of the core 1. The core supports 4 fit snugly around the top of the core 1 from top to bottom. The core supports 4 and the electrode tab supports 3 are fitted together using clips 311 and slots 45. Finally, the entire assembly is covered with the insulating film 5.

[0069] In the battery of this embodiment, the electrode plate 2 passes through the terminal hole and fits into it. The electrode tab bracket 3 supports the electrode plate 2 to ensure that it does not tilt after assembly, thus ensuring the welding yield of the electrode plate 2 and the terminal. The cover plate assembly 100 includes a cover plate 101 and a sealing ring 102. The cover plate 101 is a smooth aluminum sheet. Since the smooth aluminum sheet is a metal conductor, the battery insulation protection needs to ensure that the electrode tab and the smooth aluminum sheet do not come into contact. The retaining edge 44 at the top of the through hole of the core bracket 4 is nested with the sealing ring 102 at the bottom of the terminal to ensure the insulation protection between the electrode tab and the smooth aluminum sheet. The second receiving groove 43 on the core bracket 4 is located between the smooth aluminum sheet and the electrode tab to ensure the insulation between the electrode tab and the smooth aluminum sheet.

[0070] Overall, the battery comprises a cover assembly 100, a core assembly, and a casing 200. The core assembly consists of a core 1, electrode plates 2, a tab support 3, a core support 4, and an insulating film 5. The tab support 3 is positioned between the electrode plates 2 and the core 1, ensuring effective support of the electrode plates 2 in the height direction and improving the assembly yield of the electrode plates 2 and the terminals. The tab support 3 is elongated, with its second support surface in the middle primarily supporting the tabs. A reinforcing rib 324 is provided on the back of the second support surface to ensure the structural strength of the tab support 3 and prevent deformation after injection molding. First support surfaces 321 are designed at both ends of the second support surface, directly contacting and supporting the lower surface of the electrode plates 2. The bottom surface opposite the first support surface 321 is the third support surface, supporting the end face of the core 1. The core support 4 has corresponding electrode tabs... The mounting positions of the ear and electrode bracket 3 are provided with positioning through holes 41. A retaining edge 44 is designed around the positioning through hole 41. The positioning through hole 41 has an assembly gap with the electrode bracket 3 and the electrode plate 2 to ensure that they can pass smoothly through the positioning through hole 41. The electrode bracket 3 is accommodated inside the retaining edge 44. The top of the retaining edge 44 abuts against the sealing ring 102 to ensure that the electrode does not come into contact with the light aluminum sheet. For the electrode bracket 3 and the core bracket 4, the electrode bracket 3 is mounted on the core bracket 4. The electrode bracket 3 is fixed to the core bracket 4 by a clip 311. The core bracket 4 is designed with a first receiving groove 42 corresponding to the mounting position of the electrode bracket 3 to prevent the electrode bracket 3 from exceeding the lower surface of the core bracket 4 after assembly. The core bracket 4 is provided with a second receiving groove 43 to prevent the core 1 from being damaged after being pressed against the end face of the core 1.

[0071] This embodiment also provides a vehicle, including a vehicle body and the aforementioned battery, with the battery installed in the vehicle body.

[0072] In the vehicle of this embodiment, a tab bracket 3 is provided between the core 1 and the electrode plate 2. The tab bracket 3 abuts against the core 1, and the electrode plate 2 is supported by the first support surface 321 on the tab bracket 3. The tab of the core 1 is accommodated and supported by the support groove 322 recessed on the first support surface 321. Thus, the electrode plate 2 can be reliably supported and fixed on the basis of abutting the tab, ensuring the position and orientation of the electrode plate 2, and improving the efficiency and quality of the assembly of the core assembly and the cover plate assembly 100.
