Description

Technical Field

[0001] This utility model relates to an assembly structure, and more particularly to a rechargeable sodium battery to dry cell battery assembly structure. Background Technology

[0002] Most AA batteries currently available are nickel-metal hydride rechargeable batteries, nickel-cadmium rechargeable batteries, alkaline zinc-manganese batteries, or ordinary acidic zinc-manganese batteries. There are no products that convert sodium batteries to dry cell batteries, nor is there such an assembly structure. The chemical reactions that occur inside dry cell batteries are usually irreversible. Taking the common zinc-carbon dry cell battery as an example, its basic working principle is to generate current through the redox reaction between zinc and manganese dioxide. Once the discharge is complete, the internal chemical substances have been transformed into other compounds. These compounds cannot be converted back into the original active materials by a simple external power source, resulting in the dry cell battery being unrechargeable and having a limited capacity. Utility Model Content

[0003] In order to overcome the shortcomings of dry cell batteries, which are usually irreversible due to the chemical reactions inside the batteries, resulting in the batteries being unrechargeable and having limited power, the technical problem of this utility model is to provide a rechargeable sodium battery to dry cell battery assembly structure.

[0004] The technical implementation scheme of this utility model is as follows: a rechargeable sodium battery to dry cell assembly structure, including a cell, a cap, a PCB support frame, a PCB, a PCB spring and a negative electrode insulating sheet. The cap is provided at the upper end of the cell, the negative electrode of the cell is attached to the PCB support frame, the PCB is connected to the top of the PCB support frame, the PCB and the cap are tightly attached, the PCB spring is integrated at the bottom of the PCB, the positive electrode of the cell is attached to the PCB spring, and the negative electrode insulating sheet is pasted on the top of the cap.

[0005] In a preferred embodiment of this utility model, the bottom of the PCB has a built-in Type-C charging port.

[0008] In a preferred embodiment of this utility model, the sliding cover has anti-slip texture.

[0009] In a preferred embodiment of this utility model, the PCB passes through the cap and the negative electrode insulating sheet.

[0010] Compared with the prior art, the present invention has the following advantages: The present invention assembles the PCB on the PCB support frame and assembles the cap onto the battery cell. The cap and the battery cell are assembled by interference fit to complete the assembly of the finished battery cell. The plug can be inserted into the cap through the notch for charging. This assembly process is simple, has charging function, long cycle life, and is safe and environmentally friendly. Attached Figure Description
