[0031] Bottom plate 1;

[0032] A side frame 2, the side frame 2 is fixedly connected to the upper end of the bottom plate 1;

[0033] A protrusion 5, the protrusion 5 is fixedly connected to the side end of the side frame 2;

[0034] The connecting piece 6 is connected to the side end of the protrusion 5 . The side end of the connecting piece 6 is provided with a bayonet 7 , which matches the protrusion 5 .

[0035] In a specific embodiment of the utility model, the bottom plate 1 serves as the base of the connecting piece, providing a support and stable foundation for the entire connecting piece. The side frame 2 is fixedly connected to the upper end of the bottom plate 1, providing an additional support structure for the connecting piece, so that the connecting piece maintains the correct position and shape. The protrusion 5 is fixedly connected to the side end of the side frame 2. The protrusion is used to contact and connect a part of other components. For example, they can contact the contact point of the battery cell. The connecting piece 6 is connected to the side end of the protrusion 5. This piece of component is responsible for electrical connection, connecting the circuits of the battery cells to ensure the flow of current. The bayonet 7 is located at the side end of the connecting piece 6. It is a structure used to fix and keep the connecting piece in the correct position. It matches the protrusion 5 and can ensure the stability of the connecting piece and the reliability of contact.

[0036] For details, please refer to Figure 2-Figure 4 A rectangular block 3 is fixedly connected to the upper end of the side frame 2, and a circular hole 4 is opened at the lower end of the rectangular block 3.

[0037] In this embodiment: the rectangular block 3 is fixedly connected to the upper end of the side frame 2 to increase the structural strength and stability of the side frame. The design of the rectangular block can provide additional support to withstand mechanical stress, and also helps to maintain the shape and structural integrity of the entire connecting piece. The circular hole 4 is located at the lower end of the rectangular block 3, and the circular hole is used to achieve connection or fixation with other components. For example, the circular hole can be used to pass a screw or bolt to firmly connect the rectangular block 3 and the side frame 2 or other components together. Such a design can ensure that the connecting piece can be stably fixed in the battery pack to prevent displacement during use. In general, the rectangular block 3 and the circular hole 4 are components of the connecting piece, and they work together to provide structural support and achieve connection to ensure the stability and reliability of the lithium battery connecting piece.

[0038] For details, please refer to Figure 1-Figure 3 A circular groove 8 is formed at the upper end of the connecting piece 6, a spring 9 is fixedly connected in the circular groove 8, and a clamping block 10 is fixedly connected to the upper end of the spring 9, and the clamping block 10 matches the circular hole 4.

[0039] In this embodiment: a circular groove 8 is provided at the upper end of the connecting piece 6 of the circular groove 8, which is a structure for accommodating a spring 9. The design of the circular groove can ensure that the spring maintains the correct position in the connecting piece and provides enough space so that the spring can freely expand and contract. The spring 9 is fixedly connected in the circular groove 8, and the function of the spring is to provide elasticity when the connecting piece 6 is connected to other components. This elastic connection can absorb certain impacts and vibrations, thereby improving the stability and durability of the connection.

The clamping block 10 is fixedly connected to the upper end of the spring 9, and the clamping block is used to match the circular hole 4 on the rectangular block 3 to achieve the fixation of the connecting piece 6 with the side frame 2 or other components. When the clamping block 10 is inserted into the circular hole 4, the connection can be maintained by the pressure of the spring 9. This design can ensure the stability of the connection under vibration and thermal expansion.

[0040] For details, please refer to Figure 2 , the thickness of the bottom plate 1 is 2CM.

[0041] In this embodiment, the thickness of the bottom plate 1 is 2 cm, which is a design choice to balance multiple factors such as mechanical strength, heat dissipation performance, space occupation and weight to achieve the best performance and reliability of the battery pack. In different application scenarios and design requirements, the thickness of the bottom plate will vary.

[0042] For details, please refer to Figure 1 , the height of the side frame 2 is 3CM.

[0043] In this embodiment, the height of the side frame 2 is 3 cm, which is a design choice to balance factors such as structural stability, space design, weight distribution and heat dissipation performance to achieve the best performance and reliability of the battery pack. The height of the side frame will vary in different application scenarios and design requirements.

[0044] For details, please refer to Figure 1 and Figure 2 , the height of the rectangular block 3 matches the connecting piece 6.

[0045] In this embodiment, when the height of the rectangular block 3 matches the connecting piece 6, better structural integration can be achieved, so that the connecting piece 6 can be more tightly combined with the rectangular block 3, thereby improving the overall stability and durability. The matching height allows the rectangular block 3 to be more accurately installed on the connecting piece 6, reducing installation errors and ensuring the accuracy and reliability of the connection.

[0046] Working principle and use process of the utility model: First, place the connecting piece 6 at the predetermined position of the bottom plate 1. Ensure that the contact surface between the connecting piece and the bottom plate is flat, and there is no interference between the connecting piece and other components of the battery pack. Place the rectangular block 3 at the predetermined position of the side frame 2. Ensure that the height of the rectangular block matches the connecting piece 6 so that the card block 10 can be smoothly inserted into the circular hole 4. Place the spring 9 in the circular groove 8 to ensure that the spring can be freely extended and retracted. Fix the card block 10 at the upper end of the spring 9 to ensure that the card block matches the circular hole 4. Insert the card block 10 into the circular hole 4 on the rectangular block 3 so that the spring 9 generates pressure to maintain the stable connection between the connecting piece 6 and the bottom plate 1. Ensure that the contact surface between the connecting piece 6 and the side frame 2 is firm and there is no looseness or gap. Check the stability of the entire connection system to ensure that all components are properly installed and tightly connected. If necessary, perform an electrical performance test to verify whether the electrical connection between the connecting piece 6 and other components is good. After confirming that the connecting piece 6 and the rectangular block 3 and other components are installed correctly, complete the installation of the battery pack. Perform a final performance check to ensure that the battery pack can work properly.
