Description

Technical Field

[0001] This application relates to the technical field of electrode post packaging, and more particularly to a packaging assembly for integrated electrode posts. Background Technology

[0002] In the packaging structure of batteries or power modules, the cover plate and electrode terminals are key components for connecting to external circuits. The cover plate typically serves as the sealing structure at the top of the battery, providing excellent sealing and insulation properties. The positive and negative terminals, acting as the positive and negative interfaces for current output, are positioned on the cover plate to facilitate the installation of the entire power supply mechanism into external devices and achieve electrical connection. Through reasonable structural design, the connection between the cover plate and the terminals must not only ensure stable electrical conduction but also possess sufficient mechanical strength and environmental adaptability to ensure the safe and reliable operation of the power supply device.

[0003] In existing technologies, to achieve stable installation of the terminals on the cover plate, a stamping and stretching process is typically used to form a fixing ring structure with a certain height and strength on the surface of the cover plate. This fixing ring surrounds the terminal and cooperates with it for positioning, thereby firmly fixing the positive and negative terminals to the cover plate. This structural form simplifies the assembly process, improves production efficiency, and enhances the connection stability between the terminal and the cover plate to a certain extent, and is widely used in the manufacturing process of various battery modules.

[0004] However, existing technology has significant drawbacks. Because the fixing ring is formed on the upper surface (i.e., the outer surface) of the cover plate, and the electrode post is directly mounted on this surface, the electrode post is constantly exposed to the external environment, making it susceptible to adverse effects such as humidity, dust, and corrosive gases. Especially in high-humidity or highly corrosive environments, the electrode post is prone to oxidation, corrosion, and even short circuits, which can affect its conductivity and lifespan, and in severe cases, even lead to safety accidents. Therefore, improving the installation structure of the cover plate and electrode post to meet assembly requirements while mitigating the adverse effects of the external environment on the electrode post has become a critical technical challenge for improving the safety and reliability of power supply devices. Utility Model Content

[0005] This application provides a packaged assembly for an integrated electrode post to solve the technical problem that the posts on existing optical cover plates are easily affected by the external environment. The technical solution is as follows:

[0006] This application provides an integrated electrode post packaging assembly, including: a cover plate body having a first surface and a second surface; a first through hole on the cover plate body, a fixing ring on the second surface, and a second through hole on the fixing ring that mates with the first through hole; and an electrode post having a first end face and a second end face arranged opposite to each other, the electrode post being mounted on the cover plate body in an inverted manner through the fixing ring.

[0007] The first end face is exposed on the first surface through the first through hole, and the second end face is exposed on the second surface through the second through hole.

[0008] In one embodiment, the fixed ring body is bent to form a first limiting wall and a second limiting wall; the first limiting wall is perpendicular to the second surface; the second limiting wall extends toward the center of the first limiting wall and is parallel to the second surface to form a limiting groove in the fixed ring body, and the pole piece is embedded in the limiting groove.

[0009] In one embodiment, the fixing ring and the cover plate body are integrally formed.

[0010] In one embodiment, the pole piece includes: a first part, which is embedded in a limiting groove, and a second end face is disposed on the end of the first part away from the first through hole; a second part, which is embedded in the first through hole, and is connected to the side of the first part away from the second end face, and the first end face is disposed on the end of the second part away from the first part, and the diameter of the second part is smaller than the diameter of the first part.

[0011] In one embodiment, an insulating layer is provided on the first part, and the insulating layer is supported between the first part and the fixing ring.

[0012] In one embodiment, a toothed first limiting structure is arranged along the circumference on the radial side of the second part; a grooved second limiting structure is arranged along the circumference on the sidewall of the first through hole, and the second limiting structure engages with the first limiting structure.

[0013] In one embodiment, it further includes a sealing ring disposed in a limiting groove, the sealing ring being supported between the first part and a portion of the cover body located in the limiting groove.

[0014] In one embodiment, a relief groove is provided on the cover plate body located on the first surface, and a first through hole is provided in the center of the relief groove and communicates with the relief groove; the integrated electrode post packaging assembly further includes: a functional layer body, which is disposed in the relief groove and in the mating gap between the first through hole and the second part, and the surface of the functional layer body facing away from the bottom of the relief groove is flush with the first surface.

[0015] Compared with existing technologies, the integrated electrode post packaging assembly proposed in the above technical solution is achieved by mounting the electrode post in a fixed ring within the cover plate body in an inverted manner, with both ends of the electrode post exposed on the first and second surfaces of the cover plate body, respectively. A closed-loop fixed ring is provided on the second surface (i.e., the inner surface) of the cover plate body, and the electrode post is embedded within it for inverted fixation, thus encapsulating the main structure of the electrode post inside the cover plate. Compared to the traditional approach of placing the fixed ring on the outer surface, this solution significantly reduces the area of ​​the electrode post directly exposed to the external environment, effectively isolating it from the corrosive effects of humidity, corrosive gases, and other adverse factors, thereby extending the electrode post's service life. The electrode post is securely connected to the cover plate body via the fixed ring, while the first end face is exposed on the first surface (outer side) of the cover plate body through a first through-hole for connection to external circuitry; the second end face is exposed on the second surface through a second through-hole for easy connection to the internal wiring of the power supply mechanism. This dual-end exposed design achieves a compact and functionally integrated terminal post mounting structure while ensuring reliable electrical connections, improving overall assembly efficiency and space utilization. Because the fixing ring is located inside the cover plate, the terminal post does not protrude excessively from the outer surface of the cover plate after installation, further reducing the likelihood of mechanical impact, dirt accumulation, and environmental corrosion. This structural design not only enhances the product's protection level but also helps improve the overall sealing and insulation performance of the battery module or power system, providing strong protection for the safe operation of the equipment under harsh conditions.

[0016] In summary, this application provides an integrated electrode terminal packaging assembly with reasonable structure, strong sealing performance, and good environmental adaptability, as well as its manufacturing method. It overcomes the defects of the terminal in the prior art that are easily affected by the external environment, and has good application prospects. It is especially suitable for fields such as battery packaging with high reliability requirements, power battery systems for new energy vehicles, and energy storage equipment.

[0037] 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.

[0038] First Embodiment

[0039] Reference Figures 1 to 7 As shown, an embodiment of this application proposes an integrated electrode post packaging assembly, which may include: a cover plate body 1 having a first surface 101 and a second surface 102; a first through hole 10 is provided on the cover plate body 1, and a fixing ring 11 is provided on the second surface 102, the fixing ring 11 having a second through hole 110 that mates with the first through hole 10; and an electrode post 2 having a first end face 202 and a second end face 201 arranged opposite to each other, the electrode post 2 being mounted on the cover plate body 1 in an inverted manner through the fixing ring 11;

[0040] The first end face 202 is exposed on the first surface 101 through the first through hole 10, and the second end face 201 is exposed on the second surface 102 through the second through hole 110.

[0041] Specifically, in the technical solution adopted in this application, the cover plate body 1 can be a light cover plate, which has an upper surface and a lower surface. In this application, the upper surface of the light cover plate is defined as the first surface 101, and the lower surface is defined as the second surface 102. The pole piece 2 is disposed on the cover plate body 1, and the opposite first end face 202 and second end face 201 on the pole piece 2 are exposed on the cover plate body 1. A first through hole 10 is provided on the cover plate body 1. The key technical point of this application is that a fixed ring 11 with a closed-loop structure is provided on the second surface 102. The fixed ring 11 has a second through hole 110 on the side opposite to the second surface 102. The second through hole 110 corresponds to the first through hole 10, so that the second through hole 110 can be connected to the first through hole 10. When the pole piece 2 is arranged in the fixed ring 11 in an inverted manner, the pole piece 2 is installed on the cover plate body 1 through the fixed ring 11. Thus, the first end face 202 is exposed on the first surface 101 through the first through hole 10, and the second end face 201 is exposed on the second surface 102 through the second through hole 110. Since the fixed ring 11 is located inside the cover plate body 1, only one end face of the pole piece, namely the first end face 202, is exposed on the first surface 101 of the cover plate body 1. This can prevent the external environment from directly corroding the sealing structure, such as humidity and corrosive gases.

[0042] Furthermore, refer to Figure 6 As shown, in some embodiments, the fixed ring 11 is bent to form a first limiting wall 111 and a second limiting wall 112; the first limiting wall 111 is perpendicular to the second surface 102; the second limiting wall 112 extends toward the center of the first limiting wall 111 and is parallel to the second surface 102 to form a limiting groove 113 in the fixed ring 11, and the pole piece 2 is embedded in the limiting groove 113.

[0043] Specifically, in the technical solution adopted in this application, in order to enable the pole piece 2 to be installed in the fixing ring 11, the fixing ring 11 is bent to form a first limiting wall 111 and a second limiting wall 112. The first limiting wall 111 is perpendicular to the second surface 102 and is used to wrap around the radial side of the pole piece 2. The second limiting wall 112 is bent toward the circular direction of the first limiting wall 111, that is, the second limiting wall 112 is bent toward the inner side of the first limiting wall 111 and is parallel to the second surface 102. The second limiting wall 112 is used to abut against the second end face 201 of the pole piece 2 and exposes part of the second end face 201 through the second through hole 110, that is, the aforementioned second through hole 110, thereby forming a limiting groove 113 in the fixing ring 11 so that the pole piece 2 can be embedded in the limiting groove 113.

[0044] Furthermore, refer to Figures 1 to 5 As shown, in some embodiments, the fixing ring 11 is integrally formed with the cover plate body 1.

[0045] Specifically, in the technical solution adopted in this application, the cover plate body 1 can be formed into a fixing ring 11 on the second surface 102 by a stretching process, and the fixing ring 11 is formed into a first limiting wall 111 and a second limiting wall 112 with a 90° angle by a riveting and bending process, so that the fixing ring 11 and the cover plate body 1 are integrally formed, effectively improving the stability of the fixing ring 11 on the cover plate body 1.

[0046] Furthermore, refer to Figure 3 and Figure 4 As shown, in some embodiments, the pole piece 2 includes: a first part 21, which is embedded in the limiting groove 113, and a second end face 201 is disposed on the end of the first part 21 away from the first through hole 10; a second part 22, which is embedded in the first through hole 10, and the second part 22 is connected to the side of the first part 21 away from the second end face 201, and a first end face 202 is disposed on the end of the second part 22 away from the first part 21, and the diameter of the second part 22 is smaller than the diameter of the first part 21.

[0047] Specifically, in the technical solution adopted in this application, since the diameter of the first part 21 is larger than the diameter of the second part 22, the first part 21 can be embedded in the limiting groove 113 so that the first part 21 can be fixedly installed in the limiting groove 113. The second part 22 is embedded in the first through hole 10. The first end face 202 is located on the side of the second part 22 away from the first part 21, and the second end face 201 is located on the side of the first part 21 away from the second part 22. This allows the first end face 202 to be exposed on the first surface 101 through the first through hole 10, and the second end face 201 to be exposed on the second through hole 110 on the fixing ring 11. This is equivalent to the second end face 201 being exposed on the second surface 102, so that the power supply equipment and the power consumption equipment can be electrically connected through the pole piece 2.

[0048] Furthermore, refer to Figure 7 As shown, in some embodiments, an insulating layer 23 is provided on the first part 21, and the insulating layer 23 is supported between the first part 21 and the fixing ring 11.

[0049] Specifically, in the technical solution adopted in this application, the insulating layer 23 can be made of liquid crystal polymer material—LCP. The insulating layer 23 is injection molded on the radial side surface of the first part 21 and part of the second end face 201. Specifically, the insulating layer 23 is set between the first part 21 and the fixing ring 11 to play an insulating role. Moreover, since the material of the insulating layer 23 has a certain rigidity and strength, it can also play a supporting role between the first part 21 and the fixing ring 11, so that the shape is more regular and the riveting size is more stable when the fixing ring 11 is riveted.

[0050] Furthermore, refer to Figure 1 and Figure 3 As shown, in some embodiments, a toothed first limiting structure 221 is arranged along its circumference on the radial side of the second part 22; a grooved second limiting structure 12 is arranged along its circumference on the sidewall of the first through hole 10, and the second limiting structure 12 engages with the first limiting structure 221.

[0051] Specifically, in the technical solution adopted in this application, after the second limiting structure 12 engages with the first limiting structure 221, it can increase the torque of the pole piece 2 in the cover plate body 1, effectively preventing the pole piece 2 from rotating randomly in the cover plate body 1, making the pole piece 2 installed in the cover plate body 1 more stable.

[0052] Furthermore, refer to Figures 5 to 7 As shown, in some embodiments, it further includes a sealing ring 3 disposed in a limiting groove 113, the sealing ring 3 being supported between the first part 21 and a portion of the cover plate body 1 located in the limiting groove 113.

[0053] Specifically, in the technical solution adopted in this application, in order to achieve encapsulation in the fixed ring 11, a sealing ring 3 is disposed in the fixed ring 11 and located in the limiting groove 113. Specifically, before installing the pole piece 2 in the limiting groove 113, the sealing ring 3 is placed in the limiting groove 113. The sealing ring 3 is supported between the surface of the first part 21 near the second part 22 and the part of the cover plate body 1 located in the limiting groove 113. When the second limiting part is bent and abuts against the second end face 201, it can drive the first part 21 to squeeze the sealing ring 3, causing the sealing ring 3 to deform in the limiting groove 113, thereby achieving the effect of encapsulating the pole piece 2 in the fixed ring 11.

[0054] Furthermore, refer to Figures 5 to 7 As shown, in some embodiments, a relief groove 13 is provided on the cover plate body 1 on the first surface 101, and a first through hole 10 is provided in the center of the relief groove 13, and the first through hole 10 communicates with the relief groove 13; the integrated electrode post packaging assembly proposed in this application also includes: a functional layer 4, which is disposed in the relief groove 13 and in the mating gap between the first through hole 10 and the second part 22, and the surface of the functional layer 4 facing away from the bottom of the relief groove 13 is flush with the first surface.

[0055] Specifically, in the technical solution adopted in this application, in order for the pole piece 2 to play its proper role on the cover plate body 1, a functional layer 4 is also covered on the cover plate body 1. The functional layer 4 can be made of polyphenylene sulfide (PPS) and is used to perform insulation or conductivity. In one embodiment, the functional layer 4 can be injection molded on the first surface 101 of the cover plate body 1 and in the fitting gap between the second part 22 of the pole piece 2 and the first through hole 10 to perform insulation. In the preferred embodiment of this application, in order to make the first surface 101 with the injection molded functional layer 4 have a certain flatness, a relief groove 13 for accommodating part of the functional layer 4 is provided on the cover plate body 1. The relief groove 13 is located on the first surface 101 surrounding the first through hole 10. During injection molding, the functional layer 4 with a certain fluidity can be injected into the relief groove 13, and part of the functional layer 4 flows into the first through hole 10 through the relief groove 13. After the relief groove 13 is filled, the first surface 101 has a certain flatness, which makes it easier to attach the insulating film on the first surface 101.

[0056] Second Embodiment

[0057] The embodiments of this application also propose a method for manufacturing an integrated electrode terminal package assembly, which may include the following steps:

[0058] A first through hole 10 is opened on the cover plate body 1 by stamping process, and the opposite surfaces on the cover plate body 1 are divided into a first surface 101 and a second surface 102.

[0059] A fixing ring 11 perpendicular to the cover plate body 1 is formed on the second surface 102 by a stretching process. The fixing ring 11 and the part of the cover plate body 1 located inside the fixing ring 11 are used to form a limiting groove 113. The bottom of the limiting groove 113 is connected to the first through hole 10, and the opening of the limiting groove 113 is the second through hole 110.

[0060] The pole piece 2 includes a first part 21 and a second part 22 with a diameter smaller than the first part 21. An insulating layer 23 is injection molded on the radial side of the first part 21 and the second end face 201 facing away from the second part 22.

[0061] A sealing ring 3 is placed in the limiting groove 113, and the pole piece 2 is inverted in the limiting groove 113, so that the sealing ring 3 is supported between the first part 21 and the part of the cover plate body 1 located in the fixing ring body 11. The first end face 202 of the second part 22 facing away from the first part 21 is exposed on the first surface 101 through the first through hole 10. Then the fixing ring body 11 is bent inward to limit the pole piece 2 in the limiting groove 113, so that the insulating layer 23 is supported between the pole piece 2 and the fixing ring body 11.

[0062] Reference Figure 8 As shown, specifically, in the technical solution adopted in this application, after the fixed ring 11 is bent by riveting, the cover plate body 1 with the electrode post 2 is placed in a two-color injection molding machine 5 to simultaneously inject functional layers 4 onto the positive and negative electrode posts on the cover plate. The functional layer 4 injected onto the positive electrode post on the cover plate body 1 is conductive, while the functional layer 4 injected onto the negative electrode post is insulating. This completes the manufacturing method of the integrated electrode post encapsulation assembly. There is no need to perform welding processes or other processes that generate high temperatures on the cover plate body 1, which effectively avoids secondary crystallization of the functional layer 4 due to high temperatures, and avoids unnecessary impact on the resistance performance of the positive electrode, the insulation performance of the negative electrode, and the corrosion resistance performance of the battery.

[0063] Furthermore, in some embodiments, it also includes: during the stamping process of forming the first through hole 10, a relief groove 13 located on the first surface 101 is formed around the first through hole 10.

[0064] A functional layer 4 is injection molded in the relief groove 13 and in the fitting gap between the first part 21 and the first through hole 10. The surface of the functional layer 4 facing away from the bottom of the relief groove 13 is flush with the first surface 101.
