The above structure, in response to the deficiencies in the existing technology, proposes an improved technical solution. When the structure is set up, it includes a shell 1, a negative electrode cover plate 2, a positive electrode cover plate 3, an insulating fixing ring 4, and a winding core 5. The winding core 5 is located inside the shell 1. The positive electrode cover plate 3 is set at one end of the winding core 5 and the shell 1, and the negative electrode cover plate 2 and the insulating fixing ring 4 are set at the other end of the winding core 5 and the shell 1. In this way, the insulating fixing ring 4 and the insulating baffle can reliably achieve the insulation performance of the battery, and the positive electrode components can be reliably connected to the shell and the winding core, and the negative electrode components can be reliably connected to the shell and the winding core, thereby improving the sealing performance. In this way, each component forms a new energy power battery with an integral structure, and the battery can be reliably used in related power vehicles to meet the use requirements. The parameters of the battery-related components are adjusted within the set range to improve the scope of application. The lithium-ion battery structure described in the utility model has a simple structure. Through the structural setting and parameter setting, the sealing and insulation performance are improved, the battery is matched with the corresponding vehicle, and the use requirements are met.

[0032] The positive electrode cover plate 3, negative electrode cover plate 2, and winding core 5 are located within the housing 1. In this structure, the housing serves as a cavity for the battery's components. The housing effectively protects the internal components and reliably seals the battery from both inside and outside, achieving a waterproofing effect.

[0033] The copper-aluminum composite rivet 2.7 of the negative electrode cover plate 2 is riveted to the negative electrode post 2.1. The copper-aluminum composite rivet 2.7 presses against the sealing ring 2.8 and the negative electrode lower molding 2.9, which in turn presses against the negative electrode stamped cover plate 2.5. The negative electrode post 2.1 presses against the negative electrode upper molding 2.3, and the negative electrode post 2.1 and the negative electrode upper molding 2.3 press against the negative electrode stamped cover plate 2.5. This structure sets the structure of the negative electrode cover plate 2 to effectively meet usage requirements.

[0034] The negative electrode post 2.1 includes a positioning blind hole 2.1.1 and a rivet assembly hole 2.1.2. When the positioning blind hole 2.1.1 is configured: 2.1.2 Rivet assembly hole structure setting: The number of the positioning blind holes 2.1.1 is 1 to 4, and the number of the rivet assembly holes 2.1.2 is 1 to 2.

[0035] The negative electrode cover plate 2 has an injection molded portion 2.3 on the negative electrode, including an insulating boss 2.3.1, a positioning boss 2.3.2, and a positioning through-hole 2.3.3. The number of insulating bosses 2.3.1 matches the number of rivet mounting holes 2.1.2. The number of positioning bosses 2.3.2 is 1 to 4, and the number of positioning through-holes 2.3.3 matches the number of positioning blind holes 2.1.1. This structure limits the components of the negative electrode cover plate 2, resulting in a structurally reliable negative electrode cover that meets the battery's operational requirements.

[0036] The negative electrode stamped cover plate 2.5 includes positioning blind holes A2.5.1, positioning blind holes B2.5.2, rivet holes 2.5.3, and air guide notches 2.5.4. The number of positioning blind holes A2.5.1 is consistent with the number of positioning through holes 2.3.3, the number of positioning blind holes B2.5.2 is consistent with the number of positioning bosses 2.3.2, the number of rivet holes 2.5.3 is consistent with the number of rivet assembly holes 2.1.2, and the number of air guide notches 2.5.4 is 1-2. The above structure defines the components of the negative electrode stamped cover plate to form a structurally reliable negative electrode stamped cover plate that meets the use requirements of the battery.

[0037] The negative electrode post 2.1 of the negative electrode cover 2 is configured as follows: 5mm ≤ negative electrode post L ≤ 400mm, 5mm ≤ negative electrode post H ≤ 120mm, and 5mm ≤ negative electrode post D ≤ 20mm. This configuration allows the negative electrode post 2.1 to be adjusted within a set range by adjusting its parameters, effectively increasing its adaptability. The negative electrode post parameters must match the relevant battery components.

[0038] When the negative electrode stamping cover plate 3.1 structure of the negative electrode cover plate 3 is set: 5mm≤negative electrode stamping cover plate third level L3.1.3≤400mm, 1mm≤the difference between the negative electrode stamping cover plate third level L3.1.3 and the negative electrode stamping cover plate second level L3.1.2≤10mm, 1mm≤the difference between the negative electrode stamping cover plate second level L3.1.2 and the negative electrode stamping cover plate first level L3.1.1≤10mm, 5mm≤negative electrode stamping cover plate third level H3.1.3≤120mm, 1mm≤the difference between the negative electrode stamping cover plate third level H3.1.3 and the negative electrode stamping cover plate second level H3.1.2≤10mm, 1mm≤the difference between the negative electrode stamping cover plate second level H3.1.2 and the negative electrode stamping cover plate first level H3.1.1≤10mm, 5mm≤negative electrode stamping cover plate D3.1.1≤20mm. The above structure, by setting the parameters of the negative electrode stamping cover plate 3.1, allows the negative electrode stamping cover plate 3.1 to be adjusted within the set range, thereby effectively improving the adaptability range and meeting battery requirements.

[0040] The sealing ring 2.8 is located between the copper-aluminum composite rivet 2.7 and the negative electrode lower molding 2.9, and the explosion-proof valve 2.6 is installed on the negative electrode post 2.1. With this structure, during battery production, the explosion-proof valve 2.6 needs to be fixedly installed on the negative electrode post 2.1, and the sealing ring 2.8 is located between the copper-aluminum composite rivet 2.7 and the negative electrode lower molding 2.9, thereby ensuring a reliable structural seal.

[0041] The new energy power battery described in the present invention includes a shell 1, a negative electrode cover plate 2, a positive electrode cover plate 3, an insulating fixing ring 4, and a winding core 5. The winding core 5 is located inside the shell 1. The positive electrode cover plate 3 is provided at one end of the winding core 5 and the shell 1, and the negative electrode cover plate 2 and the insulating fixing ring 4 are provided at the other end of the winding core 5 and the shell 1. In this way, the insulating fixing ring 4 and the insulating baffle can reliably achieve the insulation performance of the battery, and the positive electrode components can be reliably connected to the shell and the winding core, and the negative electrode components can be reliably connected to the shell and the winding core, thereby improving the sealing performance. In this way, the various components form a new energy power battery with an integral structure, and the battery can be reliably used in related power vehicles to meet the use requirements. The parameters of the battery-related components are adjusted within the set range to improve the scope of application. The lithium-ion battery structure described in the present invention has a simple structure. Through the setting of the structure and the setting of the parameters, the sealing and insulation performance are improved, the matching of the battery in the corresponding vehicle is met, and the use requirements are met.

It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
