[0002] Battery poles, as an important part of the battery, undertake the key tasks of current transmission and chemical reaction. With the rapid development of the automobile industry, the requirements for battery performance are also increasing. The design and material selection of battery poles have an important impact on the performance and life of the battery.

According to the battery pole assembly of the embodiment of the utility model, the battery pole and the current connecting piece are plugged in and matched. The device is simply fixed to the battery on the outside of the battery pole, and there is no fulcrum inside. When the force on the outside of the pole is too great, the fixation between the outside of the pole and the battery will be damaged, causing displacement between the sealing material inside the battery and the pole, resulting in a gap that makes it impossible for the sealing material to be completely sealed, thereby causing electrolyte leakage.

[0003] Therefore, it is necessary to improve a battery pole with high shear resistance in the prior art to solve the above problems. Summary of the invention

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a battery pole with high shear resistance, comprising: a base, a pole arranged at one end of the base, and a protective structure; the protective structure is arranged on the outer layer of the base and the pole, and the protective structure is arranged in contact with the outer layer of the base and the pole;

[0006] The base includes a base body, a connecting end arranged at one end of the base body, and a fixing end arranged at the other end of the base body; the connecting end and the fixing end are arranged opposite to each other; and the pole is arranged at the connecting end;

[0023] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] As shown in the figure, a battery pole with high shear resistance includes: a base 1, a pole 2 arranged at one end of the base, and a protective structure;

[0025] It should be noted that the base 1 and the pole 2 are prepared in a separate arrangement. After the preparation is completed, a protective structure is coated on the base 1 and the pole 2. The protective structure improves the corrosion resistance and wear resistance of the pole 2 and the base 1 without affecting the connection between the base 1 and the pole 2 to the inside and the outside of the battery.

[0026] The base 1 includes a base body 10, a connecting end 11 disposed at one end of the base body 10, and a fixing end 13 disposed at the other end of the base body 10; the connecting end 11 and the fixing end 13 are disposed opposite to each other; the pole 2 is disposed at the connecting end 11;

[0027] In a preferred embodiment of the present invention, the connection end 11 is arranged in an arc shape, and a connection hole 12 is provided on the connection end 11 . The connection hole 12 is used for fixed connection with the pole 2 .

[0028] In a preferred embodiment of the utility model, the fixing end 13 is provided with a protrusion on the base body 10 , the cross section of the fixing end 13 is arranged in a "X" shape, and a fixing hole 14 is arranged in the middle of the protrusion of the fixing end 13 .

[0029] It should be noted that the base 1 is composed of a base body 10 whose initial shape is a rectangular metal plate, which is then subjected to cutting and bending processes to form a fixed end 13 and a connecting end 11 at both ends, thereby forming a base 1 with a connecting end 11 and a fixed end 13 at both ends.

[0030] The connection end 11 is only subjected to a cutting process to form the connection end 11 of the base 1. First, a cutting process is performed at the end point of the rectangular metal plate to cut the sharp corner at the end point into a semicircular arc shape, and the diameter of the arc is the length of the shorter side of the horizontal plane of the rectangular metal plate. At this time, the connection end 11 is formed, and the connection end 11 is used for fixed connection with the pole 2. A connection hole 12 is also cut on the connection end 11. The circles of the connection hole 12 and the semicircular arc are located at the same point, and the size of the connection hole 12 is smaller than the connection position of the pole 2 and the diameter of the connection hole 12 is smaller than the diameter of the connecting piece 21. The reference range is 0.01mm-0.1mm, preferably 0.05mm, and the diameter of the seasonal connection hole 12 is smaller than the diameter of the connecting piece 21 by 0.01mm-0.1mm, preferably 0.05mm.

[0031] Among them, the fixed end 13 is prepared by cutting and bending processes, and the fixed end 13 is arranged opposite to the connecting end 11. The preparation of the fixed end 13 is specifically to first open a fixing hole 14 at the end of the rectangular metal plate opposite to the connecting end 11 through a cutting process, and then use this end as the fixed end 13. The center of the fixing hole 14 and the center of the connecting hole 12 are located in a vertical plane. The fixing hole 14 is used to fix the entire base 1 and the pole 2, and then bend to form a "J"-shaped protruding structure. At the same time, the fixing hole 14 is located at the center of the "J"-shaped protruding structure.

[0032] During operation, the entire base 1 is arranged inside the battery, and the base 1 is fixedly connected to the inside of the battery through the fixing hole 14 using bolts, and then the gaps between the battery pole 2, the base 1 and the battery cover are filled with sealing materials such as epoxy resin and polyurethane glue to prevent the gap between the pole 2, the base 1 and the battery from causing leakage of the battery electrolyte. At this time, the connecting hole 12 is located at the hole reserved for the pole 2 of the battery, and the pole 2 is located at the hole.

[0033] The pole 2 includes a column 20 , a connecting piece 21 arranged at one end of the column 20 , and a torque piece 22 arranged on the circumference of the column 20 ; a connecting notch is provided on the torque piece, and the connecting notch can be connected to the battery to increase the torque of the column 20 .

[0034] In a preferred embodiment of the present invention, the torque member 22 is composed of a first circular plate and a second circular plate, and the connecting notch is formed on the first circular plate.

[0035] In a preferred embodiment of the present invention, the connecting member 21 is configured in the shape of a short shaft, and the connecting member 21 and the connecting hole 12 can be interference-fitted.

[0036] It should be noted that the pole 2 is composed of a column 20, a connecting piece 21 and a torque piece 22. The column 20 is set in a cylindrical shape and is the main body of the pole 2, which is used to connect the inner and outer parts of the battery. The connecting piece 21 and the torque piece 22 are respectively arranged at one end of the column 20, and the torque piece 22 is arranged on the circumference of the end point of the column 20, and the torque piece 22 is arranged at the end point of the column 20. The column 20, the connecting piece 21 and the torque piece 22 are formed by integral casting, so that the column 20, the connecting piece 21 and the torque piece 22 are a whole, wherein the torque piece 22 is composed of a first circular plate and a second circular plate, the first circular plate is arranged at the bottom of the second circular plate, the diameter of the first circular plate is larger than the second circular plate, and a connecting notch is opened on the circumference of the first circular plate, and the connecting notch is used to increase the shear force of the pole 2 as a whole. When working, the existing Conventional technology uses sealing materials to directly perform sealing processing, and the pole 2 is cylindrical. During the connection between the external device and the battery through the pole 2, there is no fulcrum between the circular pole 2 and the sealing material. When the force on the outside of the pole 2 is too large, the fixation between the outside of the pole 2 and the battery will be damaged, and there is no fulcrum inside, which causes displacement between the sealing material inside the battery and the pole 2, thereby generating a gap, resulting in the inability to completely seal the sealing material, and then causing electrolyte leakage. In the present application, the connection notch opened on the first circular plate generates a fulcrum between the sealing material and the sealing material during the sealing process of the battery, so that even if there is a problem with the external connection point, the pole 2 of the present application can still be limited as a whole inside the battery through the fulcrum at the connection notch to avoid displacement of the pole 2 and the generation of a gap.

[0037] The second circular plate is arranged above the first circular plate. During the installation process, the connecting piece 21 is pressed together with the connecting hole 12 of the connecting end 11 of the base body 10 so that the two are interference fit. At the same time, the second circular plate is also pressed together with the reserved hole of the upper pole 2 of the battery so that the two are also interference fit, and then the sealing material is used for sealing.

[0038] The protective structure is arranged on the outer surface of the base 1 and the pole 2, and the protective structure is arranged in close contact with the outer surface of the base 1 and the pole 2;

[0039] In a preferred embodiment of the present invention, the protective structure is made of metal material to improve the wear resistance and corrosion resistance of the base 1 and the pole 2 while ensuring the electrical conductivity of the pole 2.

[0040] In a preferred embodiment of the utility model, the protective structure includes a wear-resistant layer and a corrosion-resistant layer. The corrosion-resistant layer is arranged in contact with the base 1 and the pole 2, and the wear-resistant layer is arranged in contact with the corrosion-resistant layer.

[0041] In a preferred embodiment of the utility model, the wear-resistant layer is made of titanium nitride with a thickness of 0.1mm-0.5mm, and the corrosion-resistant layer is made of polyvinyl fluoride with a thickness of 1.5μm-2μm.

[0042] It should be noted that the protective structure is composed of a wear-resistant layer and a corrosion-resistant layer. The corrosion-resistant layer is attached to the pole 2 and the base 1. The wear-resistant layer is attached to the corrosion-resistant layer. The corrosion-resistant layer is prepared by polyvinyl fluoride. After the preparation is completed, it is sprayed on the pole 2 and the base 1 by a spraying process. Polyvinyl fluoride is a polymer material. The molecular structure of polytetrafluoroethylene is very stable. The bond between the fluorine atom and the carbon atom in its molecular chain is very strong and is not easily destroyed by chemical substances. The chemical properties of PTFE are very inert and not easy to react with other substances. It will not be corroded by chemical substances such as acids, alkalis, solvents, and oxidants. Therefore, it can be used in various harsh environments. The optimal thickness of the corrosion-resistant layer prepared by polyvinyl fluoride is 1.7μm. Titanium nitride is a stable metal compound with a very high hardness of more than 2000HV, which is 2-3 times that of other cemented carbides. This high hardness enables it to resist wear and scratches, and is a preferred material for preparing wear-resistant coatings. Titanium nitride has good corrosion resistance and can work in various corrosive media without being easily corroded and oxidized. This further enhances its wear resistance in complex environments.

[0043] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
