Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a battery with a charging port. Background Technology

[0002] A rechargeable battery is a battery with a limited number of recharge cycles, which can be used after being charged with a charger. The advantages of rechargeable batteries are their reusability, economy, and environmental friendliness. Lithium-ion batteries are a type of rechargeable battery that primarily relies on the movement of lithium ions between the positive and negative electrodes to function. During charging and discharging, Li+ ions repeatedly insert and extract between the two electrodes: during charging, Li+ ions extract from the positive electrode, pass through the electrolyte, and insert into the negative electrode, leaving the negative electrode in a lithium-rich state; the reverse occurs during discharging. With the development of microelectronics technology at the end of the 20th century, miniaturized devices have become increasingly common, placing high demands on power supplies. Rechargeable lithium-ion batteries have thus entered a stage of large-scale practical application. Existing rechargeable batteries typically require a dedicated charger, which is quite inconvenient.

[0025] Reference Figures 1-5 This utility model provides a battery with a charging port, including: a steel sleeve 1, a straight plate 2, an isolation bracket 3, a protection circuit board 4, and a battery cell 5 with a groove on the positive terminal. A first plug 6 is provided at the bottom of the straight plate 2, and a charging port 7 facing the side is provided at the bottom of the straight plate 2. A second plug 8 is provided above the protection circuit board 4. The straight plate 2 and the protection circuit board 4 are connected together by the first plug 6 and the second plug 8, and the isolation bracket 3 is sandwiched between the straight plate 2 and the protection circuit board 4. A first through hole 9 corresponding to the charging port 7 is provided on the side of the isolation bracket 3. The straight plate 2, the isolation bracket 3, and the protection circuit board 4 are distributed in the groove of the battery cell 5 from top to bottom and are pressed together by the steel sleeve 1. A second through hole 10 corresponding to the charging port 7 is provided on the side of the steel sleeve 1. A positive terminal 11 is provided at the top center of the straight plate 2.

[0026] The charging port 7 can be a common charging interface such as a Type-C interface. The first plug-in 6 and the second plug-in 8 are corresponding male and female plugs used for electrical connection.

[0027] The above technical solution uses a through-plate 2 with a first plug-in 6 and a charging port 7, a protective circuit board 4 with a second plug-in 8, and an isolation bracket 3 to form a cooperative structure. The battery is fixed to the groove of the cell 5 by a steel sleeve 1, so that the battery of this utility model has a built-in charging port and can be charged directly with a conventional charging cable, which is more convenient. The overall structure is simple, the layout is reasonable, and it is easy to manufacture.

[0028] In some embodiments, the isolation bracket 3 is a ring-shaped sleeve structure, specifically, the isolation bracket 3 is made of plastic. This structural design allows the isolation bracket 3 to provide isolation and support between the through plate 2 and the protective circuit board 4, and also has an insulating effect.

[0029] A sealing ring 12 is provided on the side wall of the groove of the battery cell 5. Specifically, the sealing ring 12 is made of plastic.

[0030] In some embodiments, a positive electrode ring is provided on the bottom outer periphery of the protection circuit board 4, and an aluminum plate 13 for contacting and connecting the positive electrode ring is provided at the bottom of the groove of the battery cell 5. The aluminum plate 13 is connected to the positive electrode tab of the battery cell 5.

[0031] Furthermore, the bottom of the aluminum plate 13 is connected to the positive electrode tab via a current interruption device 14. The current interruption device 14, or CID, plays a crucial role as a common component in batteries. When the battery encounters a crisis, such as overheating, short circuit, or overcharging, the CID acts as a safety barrier. By monitoring pressure changes, when the pressure exceeds a preset threshold, the CID automatically disconnects the positive electrode lead to prevent electrolyte leakage and ensure battery safety.

[0032] In some embodiments, the steel sleeve 1 is an annular sleeve structure with an inner retaining edge at the upper end. This structure can effectively fix the object and is simple in design.
