Description

Technical Field

[0001] This utility model relates to door and window profiles, and more particularly to a jigsaw puzzle assembly based on a mortise and tenon structure and a power battery CCS assembly. Background Technology

[0002] In the core component system of power batteries, the CCS (Battery Connection System) is a key component that connects cells in series, transmits current, and integrates voltage sampling and temperature monitoring functions. Its design and production mode directly affect the safety, production efficiency, and total life cycle cost of the battery pack. Currently, traditional power battery CCS modules generally adopt an "integrated design" scheme, which relies on a whole injection-molded separator plate for the aluminum busbar and other structural components. However, the integrated design makes the CCS module a large component, which is difficult to handle and is not conducive to the development and design of automated wire-pulling equipment. At the same time, if a component in the integrated product design fails or malfunctions, it faces the situation of large-scale scrapping of the entire product due to lack of repair capabilities, resulting in large-scale scrapping and loss of finished products.

[0003] Currently, the battery industry prioritizes extremely high safety and reliability. CCS module design emphasizes flexibility and lightweight construction, while production focuses on high efficiency and ease of maintenance and inspection. Therefore, there is an urgent need for a flexibly assembleable modular assembly based on a mortise and tenon structure, as well as a power battery CCS module. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this utility model provides a jigsaw puzzle assembly and a power battery CCS assembly based on a mortise and tenon structure.

[0005] To solve the above technical problems, the technical solution adopted by this utility model is: a jigsaw puzzle component based on mortise and tenon structure, which includes multiple sets of isolation plate units that can be spliced ​​sequentially; An insert strip is integrally connected to one end of the isolation plate unit, and a plug slot is integrally connected to the other end of the isolation plate unit; The inserts and slots of adjacent isolation plate units are inserted and connected and fixed by long strip buckles.

[0006] Preferably, the plate of the insert has multiple sets of internal riveting holes, and the upper and lower groove walls of the insertion groove have the same number of external riveting holes as the internal riveting holes. When the inserts and slots of adjacent isolation plate units are connected, the inner and outer rivet holes are matched and aligned one by one.

[0007] Preferably, the elongated buckle includes an elongated main plate, on which a snap-fit ​​connector is provided, which is adapted to engage and fix in aligned inner and outer rivet holes.

[0008] Preferably, the snap-fit ​​connector has a coarse limiting section and a fine through section connecting the elongated main body plate and the coarse limiting section.

[0009] Preferably, the long strip main body plate has extended pull ears at both ends.

[0010] A power battery CCS module includes the above-mentioned mortise and tenon structure-based jigsaw puzzle component.

[0011] Preferably, each partition plate unit has an aluminum bar groove, in which an aluminum bar is installed.

[0012] Preferably, the aluminum bar groove of the isolation plate unit is integrally connected with a snap-on post, and the aluminum bar is provided with a snap-on hole adapted to the snap-on post.

[0013] Preferably, the aluminum groove of the isolation plate unit is also provided with an operation hole.

[0014] This utility model discloses a jigsaw puzzle assembly and a power battery CCS assembly based on a mortise and tenon structure.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] Example 1 This embodiment discloses a jigsaw puzzle component based on a mortise and tenon structure, which mainly includes multiple sets of isolation plate units 1 that can be spliced ​​sequentially; The structural configuration of isolation plate unit 1 is as follows: Figure 1 and Figure 2 As shown, an insert strip 2 is integrally provided at one end of each isolation plate 1 unit, and an insertion slot 4 is integrally provided at the other end of the isolation plate unit 1. Based on the structure of the insert strip 2 and the insertion slot 4, the insert strip 2 of the adjacent isolation plate unit 1 is inserted and connected to the insertion slot 4, and then an additional device is installed at the insertion strip 2 and insertion slot 4 of the adjacent isolation plate unit 1. Figure 3 The elongated buckle 9 shown is used to achieve locking and fixation.

[0026] The specific locking and fixing structure is based on the mortise and tenon joint connection principle, and includes: First, such as Figure 1 and Figure 2 As shown, multiple sets of internal riveting holes 3 are provided on the plate body of the insert strip 2. Similarly, the same number of external riveting holes 5 as the internal riveting holes 3 are provided on the upper and lower groove walls of the insertion groove 4. By adjusting the spacing between multiple sets of inner rivet holes 3 and the spacing between multiple sets of outer rivet holes 5, when the insert strips 2 and insert slots 4 of adjacent isolation plate units 1 are inserted and connected, the inner rivet holes 3 and outer rivet holes 5 are matched and aligned one by one, so that one inner rivet hole 3 is aligned with one outer rivet hole 5.

[0027] Secondly, such as Figure 3 and Figure 4 As shown, the specific structural configuration of the long strip buckle 9 is as follows: the long strip buckle 9 includes a long strip main plate 91, and the long strip main plate 91 is provided with several snap-fit ​​connectors 93. The number of snap-fit ​​connectors 93 is the same as that of the inner rivet eye hole 3 or the outer rivet eye hole 5.

[0028] The snap-fit ​​connector 93 has a coarse limiting section 93a and a fine through-hole section 93b connecting the elongated main body plate 91 and the coarse limiting section 93a. Thus, when the insert strips 2 and insertion slots 4 of adjacent partition plate units 1 are inserted and connected, the snap-fit ​​connector 93 is inserted into the inner rivet hole 3 and the outer rivet hole 5 respectively. By pressing and fixing, the coarse limiting section 93a is snapped and fixed in the rivet hole, allowing the two adjacent partition plate units 1 to be assembled. The fine through-hole section 93b maintains a certain gap with the rivet hole, and the resulting hollow structure can mitigate the effects of thermal expansion and contraction, thereby ensuring the stability of the connection.

[0029] The state after the two isolation plate units 1 are spliced ​​and assembled is as follows Figure 5 and Figure 6 As shown, the bottom surface of the connector 93 is flush with the back of the isolation plate unit 1. After the insert strip 2 and the insertion slot 4 are connected and the long strip buckle 9 is pressed to fix it, the puzzle components can be quickly, conveniently and flexibly assembled and connected.

[0030] Preferably, the two ends of the long strip main plate 91 are provided with extended pull ears 92 to make it easier to disassemble the long strip buckle 9.

[0031] In addition, it should be noted that the isolation plate unit 1 is integrally injection molded, with the insert strip and insertion groove connected as a whole; the long strip buckle 9 is also an injection molded part, which can maintain effective fastening force after the buckle head and the mortise and tenon joint of the rivet hole are fixedly connected.

[0032] In summary, for the mortise and tenon structure-based jigsaw puzzle component disclosed in this embodiment, the injection-molded separator plate is a modular design that can be spliced. Compared with the traditional integrated design, this embodiment effectively solves the pain points of traditional one-piece injection-molded separator plates, such as large size, high cost, and long sample production cycle. The modular design meets the contemporary power battery CCS component's pursuit of lightweight, easy maintenance, and automation, saving equipment development cycle and a large amount of investment in capital, manpower, and material resources.

[0033] Example 2 This embodiment discloses a power battery CCS module, which adopts the mortise and tenon structure-based jigsaw puzzle component disclosed in Embodiment 1; like Figure 5-7 As shown, the puzzle assembly has connectable partition plate units 1. Each partition plate unit is formed with an aluminum bar groove 6 and a snap-fit ​​post 8 during injection molding. An aluminum bar 10 is installed in the aluminum bar groove 6.

[0034] like Figure 8 As shown, the aluminum bar 10 has a snap-fit ​​hole 11 for the snap-fit ​​post 8. Thus, by pressing, the aluminum bar 10 can be fixed into the aluminum bar groove 6 of the partition plate through the snap-fit ​​post 8.

[0035] Preferably, an operation hole 7 is also provided in the aluminum bar groove 6 of the isolation plate unit 1. This hole allows the welding tool to more easily contact the welding part of the aluminum bar, thereby facilitating the connection of the aluminum bar 10 with other components.

[0036] Therefore, the power battery CCS module disclosed in this embodiment uses a splicable separator unit 1 with aluminum foil and other structural components. Adjacent separator units are assembled and fixed by inserts, slots, and long clips. Compared with the prior art, it has the following advantages: 1) Modular isolation plate units can be flexibly and conveniently spliced ​​and assembled. By adjusting the number of splices and the arrangement, different cell layouts can be met, and various new modules can be quickly adapted. 2) The modular isolation plate unit makes the CCS module compact in structure. When used in power batteries, it can leave more space, which is beneficial for heat dissipation and provides buffer space for the expansion of lithium batteries during cycle use. 3) The small size and standardized isolation plate better meet the needs of the automated production line. In addition, the special connection structure design of the isolation plate unit provides better convenience for disassembly and maintenance, avoiding the unfavorable situation of large-scale scrapping and inability to repair once a component of the integrated product design is damaged or malfunctions.

[0037] 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.
