Description

Technical Field

[0001] This utility model belongs to the field of new energy battery technology and relates to a battery sealing component with anti-leakage function. Background Technology

[0002] New energy power batteries refer to batteries that primarily use renewable energy as their power source. Common power batteries mainly include lithium batteries, lead-acid batteries, and sodium-sulfur batteries. Compared with traditional power batteries, new energy power batteries have advantages such as large capacity, high charge and discharge efficiency, long service life, and no lead pollution. Currently, new energy power batteries are widely used in new energy vehicles, energy storage equipment, and other fields.

[0003] However, the identification of formation nails and sealing nails in existing new energy batteries is poor. When processing lithium batteries, even if there are omissions, it is difficult to identify them in time, which reduces the safety of using new energy batteries. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A battery sealing assembly with anti-leakage function is installed at the liquid injection hole position of the cover plate of a new energy battery; it includes: a formation nail body, which is composed of an integrally formed nail post and a rubber plug;

[0006] The body of the chemically formed nail is made of a material that has a distinct color difference from the chemically formed compounds in the lithium battery and the battery cover.

[0007] As a further aspect of this utility model, the color of the chemically formed nail body includes, but is not limited to, eye-catching colors such as yellow, orange, and green.

[0008] As a further embodiment of this utility model, the upper end of the nail post is also integrally formed with an upwardly extending extension section.

[0009] The beneficial effects of this utility model are as follows: During lithium battery processing, color management is achieved; during the formation process, brightly colored formation pins are installed at the electrolyte injection hole position on the battery cover, thus marking the battery as incomplete in the formation process; after the formation process is completed, the workers replace the formation pins with equally brightly colored sealing pins and insert them into the electrolyte injection hole position, achieving sealing while simultaneously marking the completion of the process; thus achieving color management, the brightly colored formation pins and sealing pin structure allow workers to quickly inspect and identify the battery, avoiding any omissions in sealing.

It should be understood that this application is not limited to the exemplary embodiments disclosed herein. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0015] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] In the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0017] Please see Figures 1-2 In this embodiment of the utility model, a battery sealing assembly 1 with anti-leakage function is installed at the injection hole 21 position of the new energy battery cover plate 2; it includes: formation nail 1 and sealing nail 3. The formation nail 1 and sealing nail 3 are both made of materials with obvious color differences from the battery cover plate 2 in the lithium battery, and the formation nail 1 and sealing nail 3 are made of materials of different colors.

[0018] During lithium battery processing, color management is achieved. During the formation process, a brightly colored formation nail 1 is installed at the electrolyte injection hole 21 of the battery cover plate 2 to mark the battery as incomplete in the formation process. After the formation process is completed, the workers replace the formation nail 1 with a sealing nail 3, which also has a bright color effect, and insert it into the electrolyte injection hole 21 to achieve sealing and mark the completion of the process. This achieves the effect of color management. Through the structure of the brightly colored formation nail 1 and sealing nail 3, workers can quickly check and identify the battery, avoiding any omissions in sealing.

[0019] Furthermore, the colors of the chemically formed nail 1 and the sealing nail 3 include, but are not limited to, more conspicuous colors such as yellow, orange, and green, which allow staff to observe and distinguish them more intuitively.

[0020] Furthermore, the chemically formed nail 1 is composed of an integrally formed nail post 11 and a rubber plug 12; while the sealing nail 3 is integrally formed by an integrally formed sealing end 32 and an embedded end 31.

[0021] Both the formation nail 1 and the sealing nail 3 are used to install at the injection hole 21 position of the battery cover 2 (please refer to the battery cover 2). Figure 3-4 As shown), injection hole 21 is a countersunk hole structure.

[0022] When the chemically formed nail 1 is installed, the rubber plug 12 is embedded into the through hole 211 of the injection hole 21 and is press-fitted to it; while the diameter of the nail post 11 is larger than the diameter of the through hole 211, and the end face of the nail post 11 abuts against the countersunk hole 212 of the injection hole 21, covering and sealing the through hole 211.

[0023] The sealing end 32 of the sealing nail 3 has a columnar structure and is inserted into the liquid injection hole 21 of the battery cover plate 2, corresponding to the hole shape of the liquid injection hole 21, and the sealing end 32 is press-fitted with the liquid injection hole 21; after the sealing nail is installed, the sealing work of the liquid injection hole 21 is achieved through the sealing end 32.

[0024] The embedded end 31 serves as a guide for the installation of the sealing nail. The lower end of the embedded end 31 has a tapered structure, which makes it easier and more accurate to insert the embedded end 31 into the injection hole 21.

[0025] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
