Description

Technical Field

[0001] This application relates to the technical field of battery cover plates, and more particularly to a battery cover plate for fixing terminal posts. Background Technology

[0002] As a crucial component of battery modules, the battery cover's design not only affects the battery's aesthetics but also its safety and functionality. Smooth covers are increasingly used in battery cover design, primarily serving to enhance the appearance and protect the internal structure. However, in practical applications, effective isolation between the smooth cover and the battery terminals is essential. This is because the battery terminals are critical for the output of positive and negative current; direct exposure could lead to short circuits. Furthermore, during battery operation, the terminals may release harmful chemical components, all of which require appropriate isolation measures to prevent damage to the smooth cover or safety issues.

[0003] Currently, PPS (polyphenylene sulfide) plastic is widely used in the industry as the insulating material between the battery cover and the battery terminals. PPS plastic is widely used due to its excellent heat resistance, good electrical insulation properties, and outstanding chemical stability. It can effectively block the battery terminals from contact with the external environment, preventing electrical accidents caused by accidental contact, and can also isolate the chemical components that the terminals may release, thus protecting the battery cover from corrosion and damage. In addition, PPS plastic also possesses a certain degree of mechanical strength, which can enhance the structural stability of the entire battery cover to some extent.

[0004] While PPS plastic performs well in many aspects, the existing solution still has significant shortcomings. Specifically, PPS plastic is generally fixed to the cover plate by adhesive bonding. Although this method is simple, it is particularly vulnerable to various forces during actual use. Especially when the insulating component is subjected to external forces such as torque, the adhesive points easily become weak points, causing the PPS plastic insulating component to detach. Once this happens, it not only damages the overall aesthetics of the battery cover plate, but more importantly, it seriously affects the battery's safety performance, increasing the risk of short circuits and other safety hazards. Therefore, how to improve the existing technology to ensure that the insulating component is more securely connected to the cover plate has become an urgent problem to be solved. Utility Model Content

[0005] This application provides a battery cover for fixing terminals. By forming an anti-rotation structure on a first limiting portion and applying an insulating component to the anti-rotation structure, the technical problem of the insulating component on the battery cover easily detaching under torsional force is solved. The technical solution is as follows:

[0006] This application provides a battery cover for fixing a terminal post, comprising: a light cover plate having a mounting position, a first limiting portion, and a second limiting portion; the mounting position being for accommodating the terminal post; the first limiting portion being located at the top of the mounting position, and the second limiting portion being located at the bottom of the mounting position; the first limiting portion and the second limiting portion forming a groove in the mounting position; the groove being for preventing the terminal post from detaching from the mounting position; and an insulating component, bonded to the first limiting portion, for isolating the light cover plate from the terminal post.

[0007] An anti-rotation structure is formed on the first limiting part, and the insulating component acts on the anti-rotation structure to restrict the relative rotation between the first limiting part and the insulating component.

[0008] In one embodiment, the insulating component includes: a first insulating member having a receiving groove for enclosing a first limiting portion, the groove wall of the receiving groove covering the outer surface of the first limiting portion and the outer end of the first limiting portion; the anti-rotation structure includes: a first anti-rotation hole disposed on the outer surface of the first limiting portion, the first insulating member partially extending into the first anti-rotation hole.

[0009] In one embodiment, the insulating component includes: a second insulating member, a first side of which covers the inner surface of the first limiting portion, and a second side of which is opposite to the first limiting portion for covering the pole post; the anti-rotation structure includes: a second anti-rotation hole disposed on the inner surface of the first limiting portion, and a portion of the second insulating member extending into the second anti-rotation hole.

[0010] In one embodiment, a third anti-rotation hole is formed on the second insulating member, and a first limiting portion extends into the third anti-rotation hole to restrict the relative rotation of the first limiting portion and the second insulating member.

[0011] In one embodiment, the first limiting part has a bent structure, and the outer end of the first limiting part extends toward the center point of the mounting position; the second limiting part is connected to the side wall of the mounting position, and the outer end of the second limiting part extends toward the center point of the mounting position to form a slot in the mounting position.

[0012] In one embodiment, it further includes a sealing ring disposed in the mounting position, the sealing ring being located between the second limiting portion and the second insulating member, for sealing the gap between the second insulating member and the pole post and the second limiting portion.

[0013] In one embodiment, an annular groove is provided on the inner surface of the second limiting part, and the sealing ring is partially embedded in the annular groove.

[0014] In one embodiment, the sealing ring includes: a compression portion disposed between the second limiting portion and the pole post in an interference fit manner, such that the side of the compression portion away from the pole post is embedded in an annular groove; and a relief portion located outside the compression portion, the relief portion being supported between the second insulating member and the second limiting portion.

[0015] The thickness of the compression portion is greater than the thickness of the relief portion, so that an abutting surface is formed on the side of the relief portion facing the second insulating member, and the abutting surface is attached to the second insulating member.

[0016] In one embodiment, a pressure relief port is provided on the cover plate, which is used to install an explosion-proof valve.

[0017] In one embodiment, it further includes: an insulating bottom cover located on the side of the light cover plate away from the first limiting portion; the insulating bottom cover is provided with a mounting base adapted to the mounting position, the mounting base being snapped into the mounting position so that the insulating bottom cover can be detachably mounted on the light cover plate.

[0018] Compared with existing technologies, the battery cover plate for fixing the terminals proposed in the above technical solution achieves significant technical benefits by forming an anti-rotation structure on the first limiting part and having the insulating component act on this anti-rotation structure. This design creates an interlocking relationship between the insulating component and the first limiting part, greatly enhancing the torsional resistance of the insulating component. Even under large torque, the insulating component remains stable and does not rotate relative to the first limiting part. This not only solves the problem of adhesive point failure caused by rotation but also significantly improves the stability and reliability of the entire battery cover plate structure. By preventing the rotation of the insulating component, the service life of the battery cover plate and its internal components is effectively extended. A stable insulating component can effectively isolate the battery terminals from the external environment for a long time, preventing current leakage and chemical corrosion, and protecting the internal battery structure from damage. Furthermore, it reduces malfunctions caused by loose or detached insulating components, lowering maintenance costs.

[0019] In summary, this application provides a simple and effective solution to prevent insulating components from rotating or falling off when subjected to torque, greatly improving the safety, durability, and practicality of the battery cover.

[0041] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0042] Reference Figures 1 to 4As shown, an embodiment of this application proposes a battery cover for fixing a terminal post 4. The battery cover may include: a light cover 1, which has a mounting position 13, a first limiting part 11, and a second limiting part 12. The mounting position 13 is used to accommodate the terminal post 4. The first limiting part 11 is located at the top of the mounting position 13, and the second limiting part 12 is located at the bottom of the mounting position 13. The first limiting part 11 and the second limiting part 12 form a groove in the mounting position 13, which is used to restrict the terminal post 4 from leaving the mounting position 13. An insulating component 2 is bonded to the first limiting part 11 to isolate the light cover 1 from the terminal post 4.

[0043] An anti-rotation structure is formed on the first limiting part 11, and the insulating component 2 acts on the anti-rotation structure to restrict the relative rotation between the first limiting part 11 and the insulating component 2.

[0044] Specifically, in the technical solution adopted in this application, the mounting position 13 provided on the cover plate 1 can be a mounting hole capable of accommodating the electrode post 4. In this embodiment, the cover plate 1 can be formed by a stamping process to create a first limiting part 11 and a second limiting part 12. It can be understood that the first limiting part 11 and the second limiting part 12 are integrally formed with the cover plate 1, thereby saving the process of welding the first limiting part 11 and the second limiting part 12. In some embodiments, the first limiting part 11 and the second limiting part 12 can also be connected to the cover plate 1 by welding. The first limiting part 11 and the second limiting part 12 are used to fix the electrode post 4 in the mounting position 13. Specifically, the first limiting part 11 is located at the top of the mounting position 13, and the second limiting part 12 is located at the bottom of the mounting position 13 to form a slot that restricts the electrode post 4 from leaving the mounting position 13. In this application, it is also necessary to separate the electrode post 4 from the cover plate 1. Therefore, an insulating component 2 for separating the cover plate 1 from the electrode post 4 is also covered on the first limiting part 11. The insulating component 2 can be made of PPS (polyphenylene sulfide) plastic material, which has good chemical resistance, can resist the corrosion of chemical substances inside the battery, can ensure stable existence in the battery working environment, and also has excellent heat resistance and cold resistance, can adapt to temperature changes during battery operation, can ensure the stability of mechanical strength at high temperatures, and will not crack at low temperatures. At the same time, it has excellent electrical insulation. In this application, an anti-rotation structure is formed on the first limiting part 11. When the insulating component 2 is adhered to the first limiting part 11, it can act on the anti-rotation structure to increase the anti-rotation strength between the insulating component 2 and the first limiting part 11, thereby effectively preventing damage to the connection structure caused by relative rotation between the insulating component 2 and the first limiting part 11, which would lead to the insulating component 2 falling off. In some embodiments, a keyway and a key that cooperates with it, such as a flat key or a spline, can be provided on the first limiting part 11, or a positioning pin or a positioning hole can be provided. Both can coexist, or they can be irregularly shaped structures, such as a meshing tooth structure.

[0045] Furthermore, refer to Figure 1 and Figure 3 As shown, in some embodiments, the insulating component 2 includes: a first insulating member 21, having a receiving groove for enclosing the first limiting portion 11, the groove wall of the receiving groove covering the outer surface of the first limiting portion 11 and the outer end of the first limiting portion 11; the anti-rotation structure includes: a first anti-rotation hole 101, arranged on the outer surface of the first limiting portion 11, the first insulating member 21 partially extending into the first anti-rotation hole 101.

[0046] Specifically, in one embodiment of the technical solution adopted in this application, the insulating component 2 includes at least a first insulating member 21 covering the outer surface of the first limiting part 11, and the first insulating member 21 is provided with a receiving groove for covering the first limiting part 11. The groove wall of the receiving groove can cover the outer surface of the first limiting part 11 and the outer end of the first limiting part 11 to prevent the outer end of the first limiting part 11 from contacting the pole post 4, so as to achieve a partial barrier between the first limiting part 11 and the pole post 4 through the first insulating member 21. The key technical point of this embodiment is that a first anti-rotation hole 101 is provided on the first limiting part 11. The first anti-rotation hole 101 is arranged on the outer surface of the first limiting part 11, and the first insulating member 21 extends into the first anti-rotation hole 101. Specifically, when PPS plastic is injected into the outer side of the first limiting part 11 and between the outer end of the first limiting part 11 and the pole post 4 to form the first insulating member 21, PPS plastic is injected into the first anti-rotation hole 101 so that the first limiting part 11 and the first insulating member 21 can jointly improve the torsional resistance.

[0047] Furthermore, refer to Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the insulating component 2 includes: a second insulating member 22, the first side of the second insulating member 22 covering the inner surface of the first limiting portion 11, and the second side of the second insulating member 22 facing away from the first limiting portion 11 for covering the pole post 4; the anti-rotation structure includes: a second anti-rotation hole, arranged on the inner surface of the first limiting portion 11, and the second insulating member 22 partially extending into the second anti-rotation hole.

[0048] Specifically, in one embodiment of the technical solution adopted in this application, the insulating component 2 includes at least a second insulating member 22 covering the outer surface of the first limiting portion 11. A first side of the second insulating member 22 covers the inner surface of the first limiting portion 11, while a second side of the second insulating member 22 facing away from the first limiting portion 11 can cover the pole post 4. It should be explained that, with the pole post 4 as the first reference, the first side refers to the outer surface of the second insulating member 22, and the second side refers to the inner surface of the second insulating member 22. The key technical point of this embodiment is that a second anti-rotation hole is provided on the first limiting portion 11, and the second anti-rotation hole is arranged on the inner surface of the first limiting portion 11, while the second insulating member 22 partially extends into the second anti-rotation hole. Specifically, when PPS plastic is injected into the gap between the inner surface of the first limiting portion 11 and the pole post 4 to form the second insulating member 22, the PPS plastic is injected into the second anti-rotation hole, so that the first limiting portion 11 and the second insulating member 22 can jointly improve the torsional resistance.

[0049] In some embodiments, the insulating component 2 may include a first insulating member 21 covering the outer surface of the first limiting portion 11 and a second insulating member 22 covering the outer surface of the first limiting portion 11; the first insulating member 21 is provided with a receiving groove for covering the first limiting portion 11, the groove wall of which can cover the outer surface of the first limiting portion 11 and the outer end of the first limiting portion 11 to prevent the outer end of the first limiting portion 11 from contacting the pole post 4, so as to achieve a partial barrier between the first limiting portion 11 and the pole post 4 through the first insulating member 21. The key technical point of this embodiment is that a first anti-rotation hole 101 is provided on the first limiting part 11. The first anti-rotation hole 101 is arranged on the outer surface of the first limiting part 11, and the first insulating member 21 extends into the first anti-rotation hole 101. Specifically, when PPS plastic is injected between the outer side of the first limiting part 11 and the outer end of the first limiting part 11 and the pole post 4 to form the first insulating member 21, PPS plastic is injected into the first anti-rotation hole 101 so that the first limiting part 11 and the first insulating member 21 can jointly improve the torsional resistance through the cooperation of the first anti-rotation hole 101 and the first limiting part 11. The first side of the second insulating member 22 covers the inner surface of the first limiting part 11, and the second side of the second insulating member 22 away from the first limiting part 11 can cover the pole post 4. It should be explained that when the pole post 4 is used as the first reference, the first side refers to the outer surface of the second insulating member 22, and the second side refers to the inner surface of the second insulating member 22. The key technical point of this embodiment is that a second anti-rotation hole is provided on the first limiting part 11, the second anti-rotation hole is arranged on the inner surface of the first limiting part 11, and the second insulating member 22 extends into the second anti-rotation hole; specifically, when PPS plastic is poured into the gap between the inner surface of the first limiting part 11 and the pole post 4 to form the second insulating member 22, PPS plastic is injected into the second anti-rotation hole so that the first limiting part 11 and the second insulating member 22 can jointly improve the torsional resistance through the cooperation of the second anti-rotation hole and the first limiting part 11.

[0050] Furthermore, referring to Figure 4, in some embodiments, a third anti-rotation hole 221 is formed on the second insulating member 22, and the first limiting portion 11 extends into the third anti-rotation hole 221 to restrict the relative rotation of the first limiting portion 11 and the second insulating member 22.

[0051] Specifically, in the technical solution adopted in this application, a protrusion may be provided on the inner surface of the first limiting part 11. The protrusion is misaligned with the second anti-rotation hole. When PPS plastic is poured into the gap between the inner surface of the first limiting part 11 and the pole post 4 to form the second insulating member 22, the second insulating member 22 partially covers the protrusion to form the third anti-rotation hole 221. The cooperation between the protrusion and the third anti-rotation hole 221 can further enhance the torsional resistance of the first limiting part 11 and the second insulating member 22.

[0052] Furthermore, refer to Figure 2 As shown, in some embodiments, the first limiting part 11 has a bent structure, and the outer end of the first limiting part 11 extends toward the center point of the mounting position 13; the second limiting part 12 is connected to the side wall of the mounting position 13, and the outer end of the second limiting part 12 extends toward the center point of the mounting position 13 to form a slot in the mounting position 13.

[0053] Furthermore, refer to Figure 1 and Figure 2 As shown, in some embodiments, it further includes a sealing ring 3, which is disposed in the mounting position 13. The sealing ring 3 is located between the second limiting part 12 and the second insulating member 22, and is used to seal the gap between the second insulating member 22 and the pole post 4 and the second limiting part 12.

[0054] Specifically, in the technical solution adopted in this application, the sealing ring 3 can be deformed by the pressure of the pole post 4, so that the sealing ring 3 is in close contact with the pole post 4 and the second limiting part 12, avoiding gaps between the sealing ring 3 and the pole post 4 and between the sealing ring 3 and the second limiting part 12, thereby increasing the contact area between the sealing ring 3 and the pole post 4 and improving the sealing effect.

[0055] Furthermore, refer to Figure 2 As shown, in some embodiments, an annular groove 102 is provided on the inner surface of the second limiting part 12, and the sealing ring 3 is partially embedded in the annular groove 102.

[0056] Specifically, in the technical solution adopted in this application, since the sealing ring 3 has deformation characteristics, the sealing ring 3 can extend into the annular groove 102 under the action of extrusion pressure, thereby further increasing the contact area between the sealing ring 3 and the second limiting part 12, thereby improving the sealing reliability, making the battery cover plate have higher airtightness, effectively preventing the power battery using the battery cover plate of this application from getting damp or water ingress, reducing the risk of overheating or explosion of the power battery, and making the power battery safer.

[0057] Furthermore, refer to Figure 2 As shown, in some embodiments, the sealing ring includes: a compression portion 31, which is disposed between the second limiting portion 12 and the pole post 4 in an interference fit manner, so that the side of the compression portion 31 away from the pole post 4 is embedded in the annular groove 102; and a relief portion 32, which is located outside the compression portion 31 and is supported between the second insulating member 22 and the second limiting portion 12.

[0058] The thickness of the compression portion 31 is greater than the thickness of the relief portion 32, so that an abutment surface 301 is formed on the side of the relief portion 32 facing the second insulating member 22, and the abutment surface 301 is attached to the second insulating member 22.

[0059] Specifically, in the technical solution adopted in this application, the sealing ring 3 is divided into a compression portion 31 located in the inner ring and a relief portion 32 located in the outer ring. The compression portion 31 corresponds to the pole post 4, and the relief portion 32 corresponds to the second insulating member 22. Thus, when the pole post 4 is assembled in the mounting position 13, the pole post 4 compresses the compression portion 31 of the sealing ring 3, and presses the side of the compression portion 31 away from the pole post 4 into the annular groove 102, while the relief portion 32 is supported between the second insulating member 22 and the second limiting portion 12. Since the key technical point of this embodiment is that the thickness of the compression portion 31 is set to be greater than the thickness of the relief portion 32, the thickness of the compression portion 31 will change when it is compressed by the pole post 4, while the thickness of the relief portion 32 will not be affected. Thus, when the pole post 4 compresses the sealing ring 3, it can effectively prevent the formation of gaps between the sealing ring 3 and the second insulating member 22, which would cause the second insulating member 22 to fail to block.

[0060] Furthermore, refer to Figure 1 As shown, in some embodiments, the cover plate 1 is provided with a pressure relief port 103, which is used to configure the explosion-proof valve 6.

[0061] Specifically, in the technical solution adopted in this application, the cover plate 1 has a through hole, which serves as a pressure relief port 103 for the cover plate 1. An explosion-proof valve 6 is installed on the cover plate 1, and the explosion-proof valve 6 is located on the pressure relief port 103. A protective film 7 can also be provided on the explosion-proof valve 6. The protective film 7 is pasted on the cover plate 1 and is used to prevent the explosion-proof valve 6 from being contaminated by dust or other contaminants.

[0062] Furthermore, refer to Figure 1 As shown, in some embodiments, it further includes: an insulating bottom cover located on the side of the light cover plate 1 away from the first limiting part 11; the insulating bottom cover is provided with a mounting base 51 adapted to the mounting position 13, the mounting base 51 is snapped into the mounting position 13 so that the insulating bottom cover is detachably mounted on the light cover plate 1.

[0063] Specifically, in the technical solution adopted in this application, the insulating bottom cover is located on the side of the light cover plate 1 away from the first limiting part 11. Specifically, it is connected by the matching buckle between the mounting base 51 and the mounting position 13 to quickly install the insulating bottom cover on the light cover plate 1, so as to realize the tool-free installation of the insulating bottom cover, which is simple to install and more convenient and quick to install and remove.
