Description

Technical Field

[0001] This application relates to the technical field of rechargeable batteries, and in particular to a tightly sealed rechargeable battery. Background Technology

[0002] Rechargeable batteries, also known as storage batteries or secondary batteries, are a type of battery that can convert electrical energy into chemical energy and store it through a charging process. When needed, the stored chemical energy can be converted back into electrical energy to supply power. They usually require an external power source to provide electrical energy. Current flows into the positive terminal and out through the negative terminal of the battery, causing an electrochemical reduction reaction inside the battery. This changes the chemical state of the positive and negative electrode materials, converting electrical energy into chemical energy and storing it inside the battery for multiple uses.

[0003] A search revealed Chinese patent application CN202223049062.0, which discloses a tightly sealed rechargeable battery, including a cell assembly and an end cap assembly. The cell assembly includes a cell component with a first terminal at one end and a first solder joint at the center of the first terminal. The end cap assembly includes a cover, a circuit board, and a connector. The cover is positioned over the end of the cell component near the first terminal. The circuit board is located between the cover and the cell component, and a charging port is connected to the circuit board, with one end extending beyond the circumference of the cover. A second solder joint is located on the circuit board. The connector is located between the cell component and the cover, with both ends connected to the first and second solder joints, respectively. This application uses welding to connect the connector to the circuit board and the cell component at both ends, ensuring a tight connection. This allows for a more secure sealing of the cell during encapsulation, preventing poor contact due to vibration and other factors, thus extending the cell's lifespan.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects: During use, the inside of the battery cell is usually sealed after encapsulation. During charging, the heat inside is not easily dissipated during the current flow, which leads to heat accumulation and an increase in the internal temperature of the battery. The high-temperature environment can cause an imbalance in the chemical reaction between the positive and negative electrode materials and the electrolyte, resulting in a decrease in battery performance and a shortening of battery life.

[0005] To address the problems mentioned in the background section, this application provides a tightly sealed rechargeable battery.

[0006] This application provides a sealed and secure rechargeable battery, which adopts the following technical solution: it includes a protective shell, characterized in that: an inner core is fixedly connected to the inner wall of the protective shell, a charging terminal is provided on the upper side of the inner core, a charging head is fixedly connected to one side of the charging terminal, a head frame is fixedly connected to the upper side of the protective shell, a positive terminal is fixedly connected to the upper side of the head frame, and the positive terminal is electrically connected to the inner core.

[0007] The charging head has an opening on its upper part, and a pressure block is slidably fitted on the inner wall of the opening. A pressing component that cooperates with the pressure block is provided on the upper side of the charging head. A blocking ring is fixedly connected to the upper side of the pressure block. Heat dissipation vents that cooperate with the blocking ring are provided on both sides of the head frame.

[0008] Optionally, the compression assembly includes a U-shaped frame fixedly connected to the upper side of the charging head and a micro spring fixedly connected to one side of the inner wall of the U-shaped frame, the lower end of the micro spring being fixed to the pressure block.

[0012] Optionally, a filter screen is fixedly connected to the lower side of the blocking ring, and the filter screen is in contact with the head frame.

[0013] Optionally, an anti-slip pad is provided on the lower side of the pressure block, and one side of the anti-slip pad is set in an arc shape.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] This invention, by setting up components such as a blocking ring, a heat dissipation vent, a movable vent, and a pressure block, enables the upper end of the charger to press against the pressure block when the charger is inserted into the charging head during charging. This causes the pressure block to move the blocking ring upwards, misaligning it with the heat dissipation vent, thereby opening the heat dissipation vent. This increases the airflow inside the head frame during charging to a certain extent, thus improving the heat dissipation effect during charging.

[0016] This invention, by setting up a compression component, enables the charger to be inserted into the charging head. The micro spring sheet compresses the pressure block downwards, and the anti-slip pad compresses the charger port, thereby improving the firmness of the charger connection and the stability during the charging process.

It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0024] This application discloses a tightly sealed rechargeable battery. For example... Figure 1-4 As shown, it includes a protective shell 1, an inner core 2 fixedly connected to the inner wall of the protective shell 1, a charging terminal 3 provided on the upper side of the inner core 2, a charging head 4 fixedly connected to one side of the charging terminal 3, a head frame 5 fixedly connected to the upper side of the protective shell 1, a positive terminal 6 fixedly connected to the upper side of the head frame 5, and the positive terminal 6 and the inner core 2 are electrically connected.

[0025] Please see Figure 3 A sealing block 12 is provided on one side of the charging head 4. The sealing block 12 is snapped into the inside of the charging head 4. After charging is completed, the sealing block 12 is inserted into the inside of the charging head 4 to protect the entrance of the charging head 4 and reduce the trouble of dust and moisture to the charging head 4.

[0026] Please see Figure 3 A reserved opening 13 is provided on one side of the head frame 5. The charging head 4 and the sealing block 12 are both set inside the reserved opening 13. The reserved opening 13 and the charging head 4 cooperate to facilitate the fixing of the charging head 4.

[0027] The charging head 4 has an opening 7 on its upper part, and a pressure block 8 is slidably fitted on the inner wall of the opening 7.

[0028] Please see Figure 3 An anti-slip pad 16 is provided on the lower side of the pressure block 8. One side of the anti-slip pad 16 is arc-shaped. When the pressure block 8 presses against the charger port, the anti-slip pad 16 contacts the charger port, further improving the firmness.

[0029] The upper side of the charging head 4 is provided with a pressing component 9 that cooperates with the pressing block 8. A blocking ring 10 is fixedly connected to the upper side of the pressing block 8. Heat dissipation vents 11 that cooperate with the blocking ring 10 are opened on both sides of the head frame 5.

[0030] Please see Figure 3 The compression assembly 9 includes a U-shaped frame 901 fixedly connected to the upper side of the charging head 4 and a micro spring 902 fixedly connected to one side of the inner wall of the U-shaped frame 901. The lower end of the micro spring 902 is fixed to the pressure block 8. When the charger is inserted into the charging head 4, the micro spring 902 presses the pressure block 8 downward, thereby improving the firmness of the charger insertion during charging and thus improving the stability during the charging process.

[0031] Please see Figure 3 An anti-detachment strap 14 is fixedly connected to the inner wall of the reserved opening 13. The upper end of the anti-detachment strap 14 is fixed to the sealing block 12. When the sealing block 12 is removed, the anti-detachment strap 14 can fix the sealing block 12 to prevent the sealing block 12 from being accidentally lost after removal.

[0032] Please see Figure 4 A filter 15 is fixedly connected to the lower side of the blocking ring 10. The filter 15 is in contact with the head frame 5. When the blocking ring 10 moves upward, the filter 15 can block the heat dissipation port 11 to prevent dust from entering the head frame 5 during charging.

[0033] The implementation principle of a tightly sealed rechargeable battery according to an embodiment of this application is as follows: When the battery needs to be recharged after use, the sealing block 12 is opened first to allow the battery to leak out, and then the matching charger is inserted. When the charger is inserted into the charging head 4, the upper end of the charger will squeeze the pressure block 8, causing the pressure block 8 to move the blocking ring 10 upward and misalign it with the heat dissipation vent 11, thereby opening the heat dissipation vent 11 and increasing the airflow inside the head frame 5 during charging to a certain extent, thereby improving the heat dissipation effect during charging.

[0034] When the charger is inserted into the charging head 4, the micro spring 902 presses the pressure block 8 downwards, and the anti-slip pad 16 presses against the port of the charger, thereby improving the firmness of the charger connection during charging and improving the stability during the charging process. When the charger is unplugged, the micro spring 902 presses the pressure block 8, which causes the sealing block 12 to seal the heat dissipation port 11 and protect the inside of the protective shell 1.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
