[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a battery cover structure that can improve the accuracy of helium detection and scanning, including a battery cover body 1. A sealing reinforcement ring 107 is integrally provided at the lower end of the battery cover body 1, and the size of the sealing reinforcement ring 107 is smaller than the size of the battery cover body 1. This structure, through the design of the sealing reinforcement ring 107, gives the bottom of the battery cover body 1 a stepped structure, allowing the battery cover body 1 to close more tightly and to be stably positioned during helium detection. On both sides of the upper end of the battery cover body 1, electrode post fixing seats 108 are integrally provided, and negative electrode post 2 and positive electrode post 4 are respectively installed on the electrode post fixing seats 108. An explosion-proof sheet 5 is provided at the upper center of the main body 1, and an electrolyte injection hole 6 is also provided on the battery cover main body 1. This structure, through the explosion-proof sheet 5, constitutes a safety component of the battery cover main body 1, preventing the battery from exploding or other dangerous situations due to excessive internal pressure under abnormal conditions. The electrolyte injection hole 6 is used for electrolyte injection. A thickened frame 106 is provided at the upper end of the battery cover main body 1, and a smooth surface 104 is integrally provided between the thickened frame 106. A scanning labeling area 3 is provided on the smooth surface 104. The outer ring of the explosion-proof sheet 5 is provided with an explosion-proof sheet protrusion 105 integrally formed with the battery cover main body 1, and an explosion-proof sheet groove 102 is also provided on the outer ring of the explosion-proof sheet protrusion 105. This structure, through the explosion-proof sheet 5, constitutes a safety component of the battery cover main body 1, preventing the battery from exploding or other dangerous situations due to excessive internal pressure under abnormal conditions. An outer protrusion 105 and an outer groove 102 are designed around the outer ring of the explosion-proof sheet 5. This reduces the thickness of the battery cover body 1 at the explosion-proof sheet 5 and ensures sufficient structural strength. The injection hole 6 is located between the explosion-proof sheet 5 and the positive electrode post 4. The standardized helium detection interface 101 and the smooth surface 104 are located between the explosion-proof sheet 5 and the negative electrode post 2. This structure, by integrating the standardized helium detection interface 101 and the scanning labeling area 3, allows for immediate helium detection after scanning. The standardized helium detection interface 101 avoids the inaccurate positioning problem caused by using electrodes and explosion-proof valves for helium detection, effectively improving the accuracy of helium detection positioning of the battery cover body 1. The upper part of the cover body 1 near the smooth surface 104 is integrally provided with a helium detection tool anti-deviation positioning protrusion ring 103. The helium detection tool can be accurately positioned by the helium detection tool anti-deviation positioning protrusion ring 103, and the battery cover body 1 can have a reliable and stable sealing structure after the helium detection is completed. The helium detection tool anti-deviation positioning protrusion ring 103 is provided with a standardized helium detection interface 101. The terminal post stabilizing seat 108 is a square platform structure, and positive and negative terminal marking rings 7 are fastened to the outside of the terminal post stabilizing seat 108 respectively. This structure uses insulating material to make the terminal post stabilizing seat 108 and distinguishes the terminal post stabilizing seat 108 by color, which can facilitate the differentiation of the negative terminal post 2 and the positive terminal post 4.

[0018] Working Principle: When using this battery cover structure that improves the accuracy of helium detection and scanning, the battery cover body 1 first installs the negative terminal 2 and the positive terminal 4 respectively through the terminal post stabilizing seat 108. Positive and negative terminal marking rings 7 are used to distinguish between the negative terminal 2 and the positive terminal 4. The explosion-proof sheet 5 is secured at the installation location through the explosion-proof sheet protrusion 105 and the explosion-proof sheet groove 102. Barcodes, QR codes, etc., are affixed to the smooth surface 104, which is flush with the upper end of the thickened frame 106, ensuring the structural strength of the battery cover body 1 while facilitating the display of barcodes and QR codes. During the helium testing of the battery cover body 1, the battery cover body 1 is positioned under the helium testing device by the sealing reinforcement ring 107. After scanning the barcode and QR code at the labeling area 3, the helium testing device performs helium testing. The helium testing fixture is connected to the standardized helium testing interface 101 by the positioning of the anti-deviation positioning protrusion ring 103. Then, the helium testing can be performed to ensure that the injection hole 6 is sealed during the helium testing process. By accurately positioning the battery cover body 1 for helium testing, the efficiency of the helium testing of the battery cover body 1 can be improved, thereby completing a series of tasks.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
