Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a novel rechargeable battery structure. Background Technology

[0002] Current rechargeable battery structures with integrated charging protection boards have significant problems. Existing rechargeable batteries with Type-C interfaces assemble structural components with Type-C interface protection boards together and then loosely place them in the battery casing. Firstly, the structural components are complex, numerous, and expensive. Secondly, battery assembly is difficult, time-consuming, has a high defect rate, and high manufacturing costs. Thirdly, the loose internal structure leads to unreliable battery performance and inability to discharge at high currents. Fourthly, the use of unsafe lithium battery cells poses safety hazards. Fifthly, the user experience is poor, and the protection board's protection function is inadequate, severely affecting battery performance. (The last sentence appears to be a separate, unrelated point: "Patent authorization announcement number CN 212323125") In the U, a Type-C interface rechargeable battery structure for optimized production and quality is disclosed. Although this structure avoids connecting the negative terminal to the Type-C interface through a wire and simplifies the structure, the protection of the Type-C interface circuit requires the use of two metal housings for combined installation. This is not only inconvenient to install and greatly affects production speed, but also relies on two nickel plates to be tightly attached to conduct electricity for the connection between the Type-C interface and the positive and negative terminals of the battery. Such a connection method is prone to poor contact and greatly affects the quality of the battery. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a new rechargeable battery structure. It has made significant innovations and optimizations to the internal structure of the battery and provided a specific assembly scheme, making the internal structure of the battery more reasonable and improving the reliability and electrical performance of the rechargeable battery as much as possible. It can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel rechargeable battery structure, comprising a rechargeable battery cell, wherein a metal protective shell is sleeved on the outer side of the upper end of the rechargeable battery cell, and the metal protective shell and the rechargeable battery cell are fixed by stamping indentations. A circuit board is disposed inside the metal protective shell, and a positive electrode spring contact pin is disposed at the center of the lower surface of the circuit board. The lower end of the positive electrode spring contact pin contacts the upper positive electrode of the rechargeable battery cell. A positive electrode post is disposed on the upper surface of the circuit board, which is conductive to the positive electrode spring contact pin. The positive electrode post penetrates through a pre-reserved through hole in the metal protective shell. A Type-C connector is welded to one side of the lower surface of the circuit board. A slot corresponding to the Type-C connector is disposed on the metal protective shell. A protective support plate is disposed between the circuit board and the upper end of the rechargeable battery cell, and a groove corresponding to the Type-C connector is disposed on the protective support plate. A negative electrode conductive spring sheet is disposed on one side of the lower surface of the circuit board, which is conductive to the inner side of the metal protective shell.

[0005] Furthermore, the positive electrode spring contact pin includes a connecting tube that is welded and fixed to the circuit board, and a spring is provided on the inner top surface of the connecting tube, with a conductive pin connected to the lower end of the spring.

[0006] Furthermore, the upper end of the conductive pin is a boss-shaped structure, and the upper end of the conductive pin slides up and down with the connecting tube.

[0007] Furthermore, a rubber insulating pad is provided between the upper surface of the circuit board and the inner top surface of the metal protective shell, and a through hole corresponding to the positive electrode post is provided on the rubber insulating pad.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: Conductivity is achieved through contact between the negative conductive spring and the metal protective shell, while the metal protective shell is fixed to the steel shell of the rechargeable battery cell for conductivity. Therefore, the Type-C connector is connected to the negative terminal of the rechargeable battery cell through the negative conductive spring and the metal protective shell, and also connected to the positive terminal of the rechargeable battery cell through the Type-C connector. This allows the Type-C connector to charge the rechargeable battery cell. The structure is simplified, and the risk of poor contact is avoided. This novel rechargeable battery structure significantly innovates and optimizes the internal structure of the battery and provides a specific assembly scheme, making the internal structure of the battery more rational and maximizing the reliability and electrical performance of the rechargeable battery.
