Abstract
Description
Technical Field
[0001] This utility model relates to CCS components, and more particularly to a detachable and recyclable injection-molded isolation plate and CCS components. Background Technology
[0002] CCS (Compact Cushion System) modules are a crucial component of new energy power battery modules, typically comprising FPC (Flexible Printed Circuit Board), aluminum cores, and injection-molded separators. In traditional FPC-type CCS modules, the aluminum cores are often thermally riveted to the injection-molded separators to meet welding requirements between the aluminum cores and battery cells. However, thermal riveting not only requires the design of riveting fixtures but also consumes a significant amount of time. Furthermore, it carries the risk of the riveting posts breaking off. Inadequate design clearance can also lead to the riveting head damaging the aluminum cores and injection-molded separators. Therefore, traditional thermal riveting suffers from drawbacks such as being time-consuming, labor-intensive, costly to produce, and posing significant safety hazards.
[0003] On the other hand, with the rapid development of new energy vehicles, the requirements for the weight and cost of automotive components are becoming increasingly stringent. As a major component of new energy vehicles, new energy power battery modules will play a crucial role in weight reduction and cost reduction. In traditional FPC-type CCS modules, the injection-molded separator structure is also fixed and cannot be disassembled. Therefore, it cannot effectively contribute to reducing costs, labor time, and cell weight. Utility Model Content
[0004] To address the shortcomings of the aforementioned technologies, this invention provides a detachable and recyclable injection-molded isolation plate and CCS assembly.
[0005] To solve the above technical problems, the technical solution adopted by this utility model is: a detachable and recyclable injection-molded isolation plate, which includes two bracket units that are assembled together;
[0006] Each support unit includes a first connecting arm and a second connecting arm; the first connecting arm of one support unit and the second connecting arm of another support unit are aligned at their ends and assembled to form a locking structure, which is used to engage and connect a limit clamp.
[0007] An aluminum bar limiting component is provided at the aluminum bar mounting groove of the support unit. The aluminum bar limiting component includes an aluminum bar limiting plate and a raised limiting block. The raised limiting block and the aluminum bar limiting plate are spaced apart to form an aluminum bar insertion limiting groove.
[0008] Preferably, the limiting clamp includes a cross brace, and side limiting plates are symmetrically distributed at both ends of the short side of the cross brace;
[0009] The upper half of the side limiting plate is positioned above the cross brace to form a pressing part;
[0010] The lower half of the side limiting plate is located below the cross brace, and an engaging angle is formed on the side of the lower half of the side limiting plate.
[0011] Preferably, the locking structure includes a first assembly structure located at the end of the first connecting arm and a second assembly structure located at the end of the second connecting arm.
[0012] The first assembly structure has a first locking groove on its side, and the second assembly structure has a second locking groove on its side.
[0013] The No. 1 and No. 2 locking slots are assembled into a locking slot, which is used to engage with the lower half of the side limiting plate.
[0014] Preferably, both the No. 1 and No. 2 locking slots have sharp corner structures to accommodate the locking angle.
[0015] Preferably, a limit block is also provided below the cross brace plate.
[0016] Preferably, the first assembly structure has a first misaligned rib, and the second assembly structure has a second misaligned rib; the first misaligned rib and the second misaligned rib are spliced together to form a limiting through hole;

[0018] Preferably, the aluminum bar limiting member is located at the edge of the bracket unit and is provided in multiple sets at intervals.
[0019] A CCS assembly includes the aforementioned removable and recyclable injection-molded partition plate.
[0020] This utility model discloses a detachable and recyclable injection-molded separator plate and CCS assembly. The aluminum bar is fixed in a fixed relative position by an aluminum bar limiting component on the separator plate to meet the requirements of cell welding. This aluminum bar limiting component structure replaces the traditional hot riveting fixing method for CCS assembly, avoiding damage to the aluminum bar and breakage of the hot riveting post. The separator plate also improves its structural strength by adding fixing points and meets the requirements for fixing the aluminum bar, offering advantages such as reduced labor time and cost savings.
[0021] Meanwhile, the isolation plate uses limit clamps and locking structures to assemble and fix the upper and lower isolation plate support units. After the aluminum bar and the battery cell are welded, the locking mechanism of the buckle (i.e., the limit clamp) is released, and the support units of the isolation plate are pulled out from the left and right to achieve the purpose of recycling. This provides effective support for reducing the weight and saving costs of new energy power battery modules. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0033] Example 1
[0034] This embodiment discloses a removable and recyclable injection-molded isolation plate, such as... Figure 1 and Figure 2 As shown, it includes two bracket units 1 that are assembled together;
[0035] Two support units 1 are assembled together to form an injection-molded isolation plate structure. The support unit 1 is made of PC material and is used to support aluminum bars, wire harnesses and other structures.
[0036] The aluminum bar is formed by stamping aluminum profiles and is mainly used for welding the positive and negative electrodes of the battery cells and for connecting the battery cells in series and parallel. In traditional CCS modules, the aluminum bar is usually connected and assembled with the injection-molded separator plate by hot riveting, which has disadvantages such as high cost, time and labor, breakage of the hot riveting post, and easy damage to the aluminum bar and injection-molded separator plate. Considering the above technical defects, the detachable and recyclable injection-molded separator plate disclosed in this embodiment is located in the support unit 1.
[0037] An aluminum bar limiting component 5 is provided at the aluminum bar mounting slot of the support unit 1, such as... Figure 1 , Figure 8 and Figure 9 As shown, the aluminum bar limiting component 5 is specifically located at the edge of the bracket unit 1 and is integrally injection molded with the bracket unit 1.
[0038] For ease of description, the aluminum bar limiting component 5 is divided into an aluminum bar limiting plate 51 and a raised limiting block 52; wherein, the raised limiting block 52 and the aluminum bar limiting plate 51 are spaced apart, thereby forming an aluminum bar insertion limiting groove between the raised limiting block 52 and the aluminum bar limiting plate 51.
[0039] Therefore, as Figure 9 As shown, the aluminum bar mounting groove and the aluminum bar limiting member 5 work together to fix the aluminum bar in the height and left and right directions, so that the aluminum bar maintains a fixed relative position to meet the requirements of cell welding.
[0040] In summary, the detachable and recyclable injection-molded separator disclosed in this embodiment, by setting aluminum bar limiting components on the separator's support unit to replace the traditional hot riveting fixing scheme, effectively improves the fit of various components of the CCS module, making its structure more coherent and simple, and creating more structural layout space for new energy power battery modules. Furthermore, by eliminating the hot riveting fixing process, the aluminum bar is better fixed while avoiding damage to the aluminum bar and breakage of the hot riveting column, offering advantages such as saving time and effort, reducing process costs, and improving safety. Moreover, the aluminum bar limiting components also add fixing points to the separator structure. By adding these fixing points, the separator's structural strength is improved while meeting the requirements for fixing the aluminum bar, effectively securing the aluminum bar within the aluminum bar mounting groove.
[0041] Example 2
[0042] This embodiment discloses a detachable and recyclable injection-molded separator plate. Based on the structure disclosed in Embodiment 1, a limiting clamp 2 and a locking structure are used to assemble and fix the two support units 1. After the aluminum bar and the cell electrode are welded, the limiting clamp 2 is released from the locking structure, and the support units 1 are pulled out to the left and right to achieve the purpose of recycling the injection-molded separator plate, thereby providing effective support for weight reduction and cost saving of new energy power battery modules.
[0043] like Figure 3 and Figure 4 As shown, each support unit 1 includes a first connecting arm 1a and a second connecting arm 1b; the first connecting arm 1a of one support unit 1 and the second connecting arm 1b of the other support unit 1 are aligned at the end positions to form a locking structure, and then the locking structure is used to engage and connect the limit clamp 2.
[0044] Among them, the limiting clamp 2 is made of PC material by injection molding and is designed as follows: Figure 5 The irregular structure shown.
[0045] For ease of description, the limiting clamp 2 is divided into a horizontal support plate 21, a side limiting plate 22, and a limiting block 23; the side limiting plate 22 has two pieces, symmetrically distributed at both ends of the short side of the horizontal support plate 21; the limiting block 23 is distributed below the plate body of the horizontal support plate 21.
[0046] The upper half of the side limiting plate 22 is positioned above the cross brace plate 21, so that the upper half of the side limiting plates on both sides together form the pressing part 22a.
[0047] The lower half of the side limiting plate 22 is located below the cross brace 21, and symmetrically distributed engagement angles 22b are formed on the side of the lower half of the side limiting plate 22.
[0048] Accordingly, such as Figure 6 and Figure 7 As shown, the positioning structure includes a first assembly structure 3 located at the end of the first connecting arm 1a and a second assembly structure 4 located at the end of the second connecting arm 1b.
[0049] A first engaging groove 32 is provided on the side of the first assembly structure 3, and a second engaging groove 42 is provided on the side of the second assembly structure 4. The first engaging groove 32 and the second engaging groove 42 are assembled together to form an engaging groove, which is used to engage with the lower half of the side limiting plate 22. At the same time, both the first engaging groove 32 and the second engaging groove 42 have a sharp corner structure to adapt to the engaging angle 22b.
[0050] Therefore, as Figure 3 and Figure 4 As shown, the limiting clamp 2 uses the lower half of the side limiting plate 22 with the engaging angle 22 to engage into the engaging groove to achieve the engaging assembly of the two support units.
[0051] Preferably, the limiting block 23 structure of the limiting clamp 2 plays a role in further fixing and strengthening. The first assembly structure 3 has a first misaligned rib 31, and the second assembly structure 4 has a second misaligned rib 41. The first misaligned rib 31 and the second misaligned rib 41 are spliced together to form a limiting through hole. The cross support plate 21 of the limiting clamp 2 spans across the spliced first misaligned rib 31 and second misaligned rib 41, and makes the limiting block 23 fit into the limiting through hole.
[0052] Therefore, the detachable and recyclable injection-molded isolation plate disclosed in this embodiment can be disassembled and recycled. By pressing the pressing part 22a of the limiting clamp 2, under the elastic action of the PC material, the side limiting plate 22 and the engaging angle 22b of the limiting clamp 2 can be disengaged from the engaging groove. At the same time, the limiting clamp 2 is pulled upward, causing the limiting block 23 to disengage from the limiting through hole, thereby releasing the limiting clamp 2 from the limiting and fixing effect on the first assembly structure 3 and the second assembly structure 4. After the limiting clamp 2 is completely disassembled, the support unit 1 of the isolation plate can be pulled out from the left and right to achieve the purpose of recycling the isolation plate. Correspondingly, the aluminum bar and the aluminum bar limiting part 5 are assembled in a plug-in manner, which will not affect the extraction operation of the support unit.
[0053] The irregularly designed limiting clamp 2, along with the matching No. 1 assembly structure 3 and No. 2 assembly structure 4, enables the limiting clamp 2 to be quickly and conveniently disassembled, thereby realizing the recycling of the injection molding isolation plate, reducing working hours, accelerating the production pace, achieving the advantages of improved production efficiency, and playing a key role in reducing costs.

On the one hand, the recycling of the injection-molded separator plate can reduce the cost of the separator plate, thereby reducing the overall cost. On the other hand, it provides strong technical support for reducing the weight of new energy power battery modules.
[0056] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
