Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to a battery cell packaging structure. Background Art

[0002] A cell refers to a single electrochemical cell containing positive and negative electrodes, which is generally not used directly. Unlike batteries, which contain protection circuits and shells and can be used directly, the composition of lithium-ion secondary rechargeable batteries is as follows: cell + protection circuit board.

[0003] In a battery cell packaging structure whose Chinese utility model patent application disclosure specification is CN209515801U, although it has a side fastening assembly for limiting and fixing the side of the cell body, and a top fastening assembly for pressing and fixing the top of the cell body, the side fastening assembly and the top fastening assembly are provided to effectively prevent the front and rear deviation of the cell body during the packaging process, which not only protects the cell body, but also prevents the deviation of the cell body, increases the success rate of the cell body packaging process, reduces costs, and saves raw materials. However, the cover and the shell are fixedly connected. If the cell body is damaged later, the entire packaging structure cannot be reused. At the same time, due to the fixed connection structure between the cover and the shell, the position of the pressing block is also fixed, and it cannot be guaranteed to be close to the outer surface of the cell body, so that the fixing effect provided by the pressing block is limited.

[0024] A battery cell packaging structure comprises a shell 1, a heat dissipation fin 2 is installed at the bottom end of the shell 1 through a mounting groove, a battery cell body 3 is arranged on the top of the heat dissipation fin 2, a positioning block 4 is fixedly arranged on the outside of the battery cell body 3 inside the shell 1, a cover 5 is arranged on the top of the shell 1, through grooves 6 are opened on the surfaces of both ends of the cover 5, and accommodating grooves 7 are opened on one side inside the through groove 6 at both ends of the cover 5, a guide rod 8 is fixedly arranged between one end of the accommodating groove 7 and the through groove 6, a connecting plate 9 is movably arranged on the outside of one end of the guide rod 8 through a mounting hole on one side inside the through groove 6, a spring 10 is installed on the outside of one end of the guide rod 8 inside the accommodating groove 7, one end of the spring 10 is fixedly connected to the connecting plate 9, a clamping block 11 is fixedly arranged on the bottom end of the connecting plate 9, clamping grooves 12 are opened on the top of both sides of the shell 1, one end of the clamping block 11 is located inside the clamping groove 12, and push blocks 13 are fixedly arranged on one end of the connecting plate 9 at both ends of the top of the cover 5;

[0025] Through the above scheme, the battery cell body 3 is built into the shell 1, and the position of the battery cell body 3 inside the shell 1 is limited by the use of the positioning block 4 to prevent the battery cell body 3 from being offset during the packaging process. Then, the cover 5 is buckled. During the buckling process, the inner wall of the shell 1 contacts the arc surface of the card block 11, and the card block 11 and the connecting plate 9 are offset along the guide rod 8 as a whole, so that the card block 11 can be extended into the shell 1. When the card block 11 is aligned with the card slot 12, the connecting plate 9 will squeeze the inner wall of the shell 1 through the tensile force of the spring 10, and the card block 11 will be embedded in the card slot 12, thereby completing the packaging of the battery cell body 3 in the shell 1.

[0026] In this embodiment, preferably, a receiving groove 14 is provided at the bottom of the cover 5;

[0027] Through the above solution, the receiving groove 14 is used to receive structures such as the threaded rod 15 and the pressing block 16;

[0028] In this embodiment, preferably, a threaded rod 15 is movably provided at the top of the receiving groove 14 through a rotating shaft, and a pressing block 16 is movably provided at the outer side of the bottom end of the threaded rod 15 through a threaded groove;

[0029] Through the above solution, the pressed block 16 is displaced to squeeze the battery cell body 3, thereby fixing the packaged battery cell body 3;

[0030] In this embodiment, preferably, a knob 17 is installed at the top of the cover 5 at one end of the rotating shaft where the threaded rod 15 is located, and a rotating rod 21 is provided on one side of the top of the knob 17 .

[0031] Through the above solution, the threaded rod 15 is driven to rotate by using the knob 17;

[0032] In this embodiment, preferably, slide grooves 18 are provided on both side surfaces of the interior of the storage groove 14 , a guide block 19 is movably provided at one end of the interior of the slide groove 18 , and a slide rod 20 is slidably connected to the inner wall of the guide block 19 .

[0033] Through the above solution, the connection between the slide groove 18 and the guide block 19 is used to provide a limiting effect for the pressing block 16;

[0034] In this embodiment, preferably, one end surface of the block 11 is arc-shaped;

[0035] Through the above scheme, when in use, the block 11 with an arc-shaped surface at one end is impacted by the inner wall of the shell 1 due to the arc surface of the block 11. The block 11 and the connecting plate 9 as a whole will be shifted along the guide rod 8 so that the block 11 can extend into the shell 1, thereby facilitating the work of fastening the cover 5.

[0036] When a battery cell packaging structure of the present embodiment is used, the battery cell body 3 is built into the shell 1, and the position of the battery cell body 3 inside the shell 1 is limited by the use of the positioning block 4 to prevent the battery cell body 3 from being offset during the packaging process. Then, the cover 5 is buckled. During the buckling process, the inner wall of the shell 1 contacts the arc surface of the card block 11, and the card block 11 and the connecting plate 9 are offset along the guide rod 8 as a whole so that the card block 11 can extend into the shell 1. When the card block 11 is aligned with the card slot 12, the connecting plate 9 will squeeze the inner wall of the shell 1 through the tensile force of the spring 10, and the card block 11 will be embedded in the card slot 12, thereby completing the packaging of the battery cell body 3 in the shell 1, and the heat dissipation fins 2 The supporting surface can ensure the heat dissipation effect of the battery cell body 3. Afterwards, the threaded rod 15 can be driven to rotate by screwing the knob 17. Due to the connection between the guide block 19 and the slide groove 18, the pressing block 16 will be displaced with the rotation of the threaded rod 15 and squeeze the battery cell body 3, thereby fixing the packaged battery cell body 3, thereby ensuring the stability of the battery cell body 3 inside the shell 1, and also making the bottom surface of the battery cell body 3 close to the upper surface of the heat dissipation fins 2, thereby improving the heat dissipation efficiency provided by the heat dissipation fins 2. When the battery cell body 3 needs to be taken out later, it only needs to push the push block 13 to disengage the card block 11 from the card slot 12 to remove the cover 5, so that the user can easily inspect the battery cell body 3.
