Abstract
Description
Technical Field
[0001] This utility model belongs to the field of battery technology, specifically relating to a battery terminal, a battery cover, and a battery. Background Technology
[0002] Currently, battery cover components are generally connected by riveting. The rivets used in these components are called terminals, and they are often assembled onto one side of the cover via a flange structure. The other end passes through the cover and is riveted to a terminal or other part. Conventional designs involve many parts, making material loading, assembly, and riveting difficult in automated production. Most often, manual assembly is used, followed by riveting from the riveting side of the cover. Therefore, this method suffers from disadvantages such as numerous structural parts, complex processing, and high cost. Summary of the Invention

[0025] The present invention will be more fully understood through the following detailed description, which should be read in conjunction with the accompanying drawings. Detailed embodiments of the present invention are disclosed herein; however, it should be understood that the disclosed embodiments are merely exemplary and that the present invention may be embodied in various forms. Therefore, the specific functional details disclosed herein should not be construed as limiting, but rather as the basis for the claims and as a representative basis for teaching those skilled in the art to employ the present invention in different ways in any suitable detailed embodiment.
[0026] Combination Figure 1 and Figure 2 As shown, the battery terminal 10 disclosed in this utility model belongs to the field of battery technology. This utility model designs the battery terminal as two parts, which mainly includes a separately set terminal body 1 and a metal sleeve 2, wherein the metal sleeve 2 is fitted onto the end of the terminal body 1.
[0027] Specifically, the electrode body 1 includes an integrally formed flange portion 11 and a connecting portion 12, with the connecting portion 12 extending downward from the lower surface of the flange portion 11. In this embodiment, the electrode body 1 has an overall riveted structure, wherein the flange portion 11 is used to fix to the front of the battery cover, and its overall shape is a horizontally placed disc with a certain thickness, and the connecting portion 12 is used to pass through to the back of the battery cover (i.e., the side near the electrolyte) for riveting, and it preferably extends downward from the middle of the lower surface of the flange portion 11, and its overall shape is a vertically placed cylinder.
[0028] The metal sleeve 2 is specifically fitted onto the end of the connecting part 12. In this embodiment, a simple interference fit is used between the metal sleeve 2 and the end of the connecting part 12. This interference fit design is easy to process, has low cost, and the material distribution is uniform after riveting, which can withstand a large pull force. After the metal sleeve 2 is fitted onto the end of the connecting part 12, it forms a cylindrical shape with the connecting part 12 having the same upper and lower outer diameters.
[0029] Preferably, the end of the connecting portion 12 is recessed inward to form a recessed portion 13, which is beneficial to the deformation of the material when the metal sleeve 2 is riveted.
[0030] Preferably, the electrode body 1 and the metal sleeve 2 are made of two different materials. In this embodiment, the electrode body 1 is made of aluminum and the metal sleeve 2 is made of copper, mainly to prevent corrosion by the electrolyte.
[0031] The present invention discloses a battery cover 20, comprising a cover body 21 and the aforementioned battery terminal 10 mounted on the cover body 21. In this embodiment, the cover body 21 includes a front cover 22 facing each other and a back cover 23 near the battery electrolyte. During installation, the battery terminal 10 is installed from the front cover 22 and riveted to the back cover 23. Specifically, the metal sleeve 2 is first installed to the end of the terminal body 1. After assembling the battery terminal 10, the flange portion 11 of the battery terminal 10 is installed on the front cover 22 (i.e., outside the battery after installation). The cylinder formed by the metal sleeve 2 and the connecting portion 12 passes through the battery cover 20 to the back cover 23 (i.e., inside the battery after installation) and is riveted from the back cover 23.
[0032] The present invention discloses a battery (not shown in the figure) including the aforementioned battery cover plate 20.
[0033] The present invention provides a battery terminal, a battery cover, and a battery, which have the following advantages: The present invention designs the terminal as two separate parts, which simplifies the structure of the terminal and meets the design requirements of the minimalist cover. During installation, the cover is first installed from the front and then riveted from the back, simplifying the complex structure into a simple and easy-to-assemble component. At the same time, it avoids high-cost processes such as welding, which is more conducive to production and incoming material control. It also facilitates automated assembly, reducing labor costs and related workstations.
