A plurality of the pressing feet are all in a bent structure facing the center of the bearing platform, and the bent part of the pressing foot presses on the bottom end of the spiral spring. An inserting piece distributed in the opposite direction to the spiral spring is arranged on the conductive sheet. Although the above utility model adopts an annularly distributed pressing foot structure, the bent part of the pressing foot can tightly clamp the bottom end of the spiral spring, so as to form a multi-point reinforcement effect on the bottom end of the spiral spring, that is, to ensure the stability of the connection state between the spiral spring and the conductive sheet. However, the battery elastic sheet structure is provided with four pressing feet for fixing the spring, and the four pressing feet need to be precisely bent to fix the spring, so that the spring needs to be more precisely aligned and fixed during installation, increasing the complexity and time cost of installation. Therefore, those skilled in the art provide a battery elastic sheet structure to solve the problems raised in the above background art. Summary of the Utility Model

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The function of the accompanying drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model. However, it should not be construed as a limitation on the protection scope of the present utility model.

[0021] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , an embodiment of the present utility model provides a battery shrapnel structure, which includes a shrapnel 11 and a spring 22. A spiral-shaped positioning portion 44 is provided inside the shrapnel 11. One end of the spring 22 close to the shrapnel 11 is provided with a bent section 66. One end of the bent section 66 opposite to the spring 22 is provided with a positioning section 77. The positioning section 77 is inserted into the inside of the positioning portion 44. On the outside of the shrapnel 11 and on one side close to the connection of the positioning section 77 and the bent section 66, there is a pressing portion 33. On the bottom of the positioning portion 44 and on one side of the end of the positioning section 77, there is a limiting portion 55. The top surface height of the limiting portion 55 is higher than the bottom surface height of the positioning portion 44, forming an additional limiting effect on the front and back positions of the positioning section 77, enhancing the connection strength between the spring 22 and the shrapnel 11, and preventing loosening or falling off caused by vibration or impact during use.

[0022] After the positioning section 77 of the spring 22 is located inside the positioning portion 44, rotate the spring 22 so that the positioning section 77 rotates a certain angle, and make the end of the positioning section 77 located on one side of the limiting portion 55. Bend the pressing portion 33 to contact the bent section 66 of the spring 22. At this time, the spiral-shaped positioning section 77 is cooperatively connected with the spiral-shaped positioning portion 44, which can limit the up and down position of the spring 22. Under the limiting action of the limiting portion 55 and the pressing portion 33, the front and back positions of the spring 22 can be limited, realizing the tight connection between the spring 22 and the shrapnel 11, preventing loosening or falling off caused by vibration or impact during use, and the overall connection operation is simple and efficient, which is beneficial to the production efficiency of the battery shrapnel structure.

[0023] The pressing portion 33 and the shrapnel 11 are provided as an integral structure. The pressing portion 33 integrated with the shrapnel 11 has sufficient strength, and the pressing portion 33 can be made by opening inside the shrapnel 11. Then, bending the pressing portion 33 to contact the outside of the bent section 66 can complete the connection work between the pressing portion 33 and the bent section 66, and the manufacturing work is simpler and more efficient. The spring 22, the bent section 66 and the positioning section 77 are provided as an integral structure. The bent section 66 and the positioning section 77 are bent from the spring 22, and the manufacturing is simple.

[0024] The shrapnel 11 and the spring 22 are both made of phosphor bronze material. The phosphor bronze material not only has good electrical conductivity but also has sufficient strength and elasticity, which can ensure that the shrapnel structure maintains a stable connection during the installation and use of the battery. Anti-corrosion coatings are provided on the surfaces of the shrapnel 11 and the spring 22. The anti-corrosion coating can be a nickel-plated layer to prevent oxidation and corrosion, extend the service life of the shrapnel structure, and improve its reliability in various environments.

[0025] Working principle: After the positioning section 77 of the spring 22 is located inside the positioning part 44, rotate the spring 22 so that the positioning section 77 rotates a certain angle, and make the end of the positioning section 77 be located on one side of the limiting part 55, bend the pressing part 33 to contact the bent section 66 of the spring 22. At this time, the spiral positioning section 77 cooperates with the spiral positioning part 44 to limit the up and down position of the spring 22. Under the limiting action of the limiting part 55 and the pressing part 33, the front and back positions of the spring 22 can be limited, realizing the tight connection between the spring 22 and the shrapnel 11, which can prevent loosening or falling off caused by vibration or impact during use, and the overall connection operation is simple and efficient, which is beneficial to the production efficiency of the battery shrapnel structure.
