Description

Technical Field

[0001] This utility model relates to the field of battery pack technology, and in particular to a die-cut insulating protective cover. Background Technology

[0002] In the current battery pack industry, the CCS assembly module is a key component, and its insulation protection is crucial. Existing battery packs primarily rely on thermoformed PC insulation covers for CCS module insulation protection. From a manufacturing perspective, thermoforming requires specialized molds, which are expensive to produce, resulting in high mold opening costs. Furthermore, the unit cost of each thermoformed PC insulation cover is also high, undoubtedly increasing the overall production cost of the battery pack and hindering large-scale production and cost control. Regarding time costs, the development cycle for thermoformed PC insulation covers is as long as 10 days. In a highly competitive market, a long development cycle means slow product iteration and an inability to quickly respond to market demands, potentially putting companies at a disadvantage in market competition. During battery pack vibration tests, the thermoformed PC insulation covers may detach, failing to provide reliable insulation protection for the CCS module and posing a significant safety hazard.

[0003] The existing technology has the following technical problems: the existing insulating protective cover is of a fixed size, which is difficult to adapt to battery packs of different lengths. Custom molds are required, which has a long development cycle and high cost. In addition, the existing protective cover only covers the surface of the aluminum busbar and is not easy to fold to cover the edges, which leads to exposed edges that are prone to short circuits, mechanical damage or dust accumulation, reducing the safety of the battery pack. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a die-cut insulating protective cover.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a die-cut insulating protective cover, comprising a protective cover, the protective cover including a first cover plate, a second cover plate and a rotating shaft, the first cover plate and the second cover plate being hinged together by the rotating shaft, the bottom surface of the protective cover being provided with adhesive backing, the side surface of the first cover plate being provided with a connecting block, the side surface of the connecting block being provided with a guide groove, the side surface of the connecting block being provided with a fixing groove, the side surface of the second cover plate being provided with a guide block, the side surface of the second cover plate being provided with a fixing block, the top surface of the fixing block being provided with a buckle, and the interior of the fixing groove being provided with a limit groove.

[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0024] Reference Figure 1-5 A die-cut insulating protective cover includes a protective cover 1 with an adhesive backing 2 on its bottom surface. The protective cover 1 is mainly made of PC sheet with a thickness of 0.15mm and is produced using a die-cutting process. The frosted surface of the PC sheet is bonded with the adhesive backing 2. The adhesive used must meet the temperature requirements of -40℃ to 105℃. The adhesive is used to bond the aluminum busbar and the vacuum-formed bracket of the CCS assembly, but it is prohibited to bond the FPC of the CCS assembly. This method enhances the bonding force with the CCS assembly and achieves the insulating protection function of the CCS assembly. Compared with traditional vacuum-formed PC insulating protective covers, it has advantages such as low cost and short development cycle. The protective cover 1 includes a first cover plate 101, a second cover plate 102, and a rotating shaft 103. The first cover plate 101 and the second cover plate 102 are connected by the rotating shaft. The first cover plate 101 and the second cover plate 102 are fixedly connected by the first cover plate 101 and the second cover plate 102 through the fixing bolt 12. The first cover plate 101 and the second cover plate 102 together constitute the main body of the protective cover 1. The first cover plate 101 and the second cover plate 102 are connected by the rotating shaft 103, so that the two can rotate relative to each other. This provides rotational support for the first cover plate 101 and the second cover plate 102 to achieve 90° rotation, ensuring that the protective cover 1 can flexibly adjust the coverage range to adapt to different usage scenarios. The relative position of the first cover plate 101 and the second cover plate 102 is fixed by the fixing bolt 12. After the first cover plate 101 and the second cover plate 102 are rotated to a suitable angle, they are fixed by the fixing bolt 12 to maintain a stable coverage state.

[0025] The first cover plate 101 has a connecting block 3 on its side, a guide groove 4 on its side, and a fixing groove 5 on its side. The sides of the guide groove 4 and the fixing groove 5 are connected. The second cover plate 102 has a guide block 7 on its side and a fixing block 8 on its side. Both the fixing groove 5 and the fixing block 8 are T-shaped, and the shape and position of the fixing block 8 are adapted to the fixing groove 5. The guide block 7 and the fixing block 8 are integrally formed. The guide groove 4 cooperates with the guide block 7 on the second cover plate 102. During the assembly of the first cover plate 101 and the second cover plate 102, the relative movement between the first cover plate 101 and the second cover plate 102 is stable and accurate, improving assembly efficiency and structural stability. The fixing groove 5 is adapted to the T-shaped fixing block 8 on the second cover plate 102. The two cooperate to achieve a reliable connection between the first cover plate 101 and the second cover plate 102, enhancing the overall stability of the protective cover 1. The top surface of the fixing block 8 is provided with a buckle. 9. A groove 10 is formed on the top surface of the fixing block 8, and the buckle 9 is set on the surface of the groove 10. A limiting groove 11 is formed inside the fixing groove 5. The shape and position of the buckle 9 are adapted to the limiting groove 11. The buckle 9 has a certain elastic deformation. When the fixing block 8 is inserted into the fixing groove 5, the buckle 9 is pressed downward and deformed, falling into the groove 10. When the buckle 9 is fully inserted, the buckle 9 returns to its original shape and is engaged in the limiting groove 11, thus realizing the connection between the first cover plate 101 and the second cover plate 102. Locking prevents accidental separation. With the cooperation of the movable groove 6, it is convenient for personnel to press down the buckle 9 to connect and separate the fixed block 8 and the fixed groove 5. The position of the buckle 9 corresponds to the movable groove 6. The top surface of the connecting block 3 is provided with the movable groove 6, and the movable groove 6 is connected to the top surface of the limiting groove 11. When disassembling the protective cover 1, it is convenient for the operator to press the buckle 9 through the movable groove 6 to make it disengage from the limiting groove 11, so as to separate the first cover plate 101 and the second cover plate 102.

[0026] During operation, firstly, based on the actual size of the battery pack, align the guide block 7 on the side of the second cover plate 102 with the guide groove 4 on the side of the connecting block 3 of the first cover plate 101, so that the fixing block 8 can be smoothly inserted into the fixing groove 5. During the insertion process, the buckle 9 on the top surface of the fixing block 8 will be pressed down to generate elastic deformation and fall into the groove 10. After full insertion, the buckle 9 returns to its original shape and locks into the limiting groove 11. If adjustment or disassembly is required, the buckle 9 can be pressed through the movable groove 6 on the top surface of the connecting block 3 to disengage it from the limiting groove 11. After assembly, it is adhered to the aluminum busbar and blister bracket of the CCS assembly with the backing adhesive 2, taking care to avoid the FPC, so as to wrap the edge of the aluminum busbar, enhance the bonding force and insulation protection effect. Then, the first cover plate 101 or the second cover plate 102 near the edge is rotated 90 degrees by the rotating shaft 103 and fixed by the fixing bolt 12. At the same time, it is pasted to the side of the battery pack with the backing adhesive 2. The whole process is simple and efficient, effectively improving the reliability and service life of the battery pack. Specific Implementation Example 2:

[0028] A die-cut insulating protective cover, based on the basic structure in Specific Embodiment 1, further discloses the following: the first cover plate 101 and the second cover plate 102 are folded by rotating shaft 103. The specific folding position can be designed according to the actual situation, ensuring that the folding position corresponds to the position where the battery pack needs to be folded and wrapped, so that the first cover plate 101 or the second cover plate 102 can be fully folded and pasted. In addition to setting one rotating shaft 103 for folding, two or three rotating shafts 103 can also be set on the surface of the protective cover 1 for folding. The specific design is based on the actual size and situation, which improves the adaptability of the protective cover 1 to battery packs of different specifications. This multi-rotating shaft 103 design not only improves the versatility of the protective cover 1, but also further optimizes the insulation protection effect, reduces safety hazards caused by poor adaptability, and provides a more reliable guarantee for the stable operation of the battery pack.

[0029] In summary:

[0030] 1. The protective cover 1, fixing block 8, buckle 9, and fixing groove 5 are adopted. The production process is changed from vacuum forming to die cutting, which reduces the development cycle, saves materials, and reduces costs. In addition, the adhesive backing 2 ensures that the protective cover 1 will not fall off during vibration testing and has a stronger bonding force. Furthermore, the protective cover 1 is formed by hinged first cover plate 101 and second cover plate 102 through rotating shaft 103. The first cover plate 101 and second cover plate 102 can be rotated 90 degrees by fixing bolt 12 and rotating shaft 103. The fixing bolt 12 and adhesive backing 2 are used to fix the first cover plate 101 and second cover plate 102. The second cover plate 102 folds to cover the edge, thus wrapping the edge of the aluminum busbar. There is no loosening during vibration testing, which effectively improves performance and increases the reliability and service life of the battery pack. At the same time, when dealing with battery packs of different lengths, there is no need to customize molds. The fixing block 8 on the second cover plate 102 is inserted into the fixing groove 5 of the connecting block 3 of the first cover plate 101, so that the buckle 9 on the fixing block 8 is engaged in the limiting groove 11. With the help of the guide block 7 and the guide groove 4, quick assembly and adaptation can be achieved.
