Description

Technical Field

[0001] This utility model relates to CCS components, and more particularly to a CCS component for a fixed temperature sensor. Background Technology

[0002] With the rapid development of the new energy vehicle industry, higher requirements have been placed on the lightweighting and cost control of various components in power battery modules. In new energy power battery modules, the CCS module is one of the key components, and the way its temperature sensor is fixed directly affects the overall performance and cost of the module. Traditional temperature sensor modules use a top-cover acquisition and fixing structure, which has the following main technical limitations:

[0003] First, due to limitations in vacuum forming technology and material thickness, traditional structures cannot effectively fix the temperature sensor, necessitating the addition of injection-molded structural components. Specifically, two connecting aluminum brackets are used in conjunction with the bottom structure for fixation, and then the temperature sensor assembly is assembled with rivets on the injection-molded structural components and hot-riveted to achieve final fixation. This fixing method not only increases the complexity of the structure but also leads to an increase in the amount of bracket material used, thereby driving up material costs.

[0004] Secondly, traditional fixed structures place high demands on molds, significantly increasing mold design and manufacturing costs. This not only affects production costs but also limits the flexibility of the production process. Therefore, existing top-cover temperature sensor mounting structures face significant challenges in meeting the requirements for lightweighting and low cost, necessitating a more optimized solution.

[0005] In summary, traditional temperature sensor mounting structures have significant shortcomings in terms of material usage and mold costs, making them difficult to meet the stringent requirements of the new energy vehicle industry for lightweight components and cost control. Therefore, it is necessary to improve and optimize them. Utility Model Content

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] In this embodiment, Figure 1 and Figure 2 A CCS assembly for a fixed temperature sensor is shown, comprising:

[0030] The injection-molded isolation plate 3 serves as the main support structure of the component. It has a through groove for installing the aluminum bar. Specifically, the through groove is an opening or groove on the injection-molded isolation plate. Its shape and size match the cross-section of the aluminum bar. The width and depth of the through groove are designed to ensure that the aluminum bar can be smoothly embedded and firmly fixed on the injection-molded isolation plate.

[0031] Aluminum bar 1 is matched and installed in the through groove of the injection molded isolation plate. A square groove is opened on the aluminum bar for installing the protective block of the temperature sensor assembly.

[0032] The temperature sensor assembly includes a protective block 2 that is fitted into a square slot. The protective block is aligned with the square slot on the aluminum plate, ensuring a perfect match between the shape of the protective block and the contour of the slot. A temperature sensor 7 is embedded within the protective block, and its pins are soldered to pads on the flexible circuit board below. A reinforcing plate is connected to the flexible circuit board directly below the pads via insulating adhesive, ensuring the reliability of the solder joints and stable transmission of electrical signals. The flexible circuit board is mounted on an injection-molded isolation plate 3 for signal acquisition and transmission. The flexible circuit board is attached to the injection-molded isolation plate using adhesive or mechanical fastening to ensure its stability within the assembly. Temperature sensor models include NTC (Negative Temperature Coefficient Thermistor) or PTC (Positive Temperature Coefficient Thermistor), with the specific model selected based on the temperature detection range and accuracy requirements, such as NTC 10K or PTC 100. The reinforcing plate is typically made of materials such as FR4 (glass fiber reinforced epoxy resin) or polyimide (PI), which have good mechanical strength and insulation properties. Flexible circuit boards typically use polyimide (PI) or polyester (PET) as the substrate.

[0033] The protective block of the temperature sensor assembly is embedded in a square groove. The square groove abuts and limits the protective block in the X-axis direction, preventing movement in that direction. A protrusion on the side wall of the protective block engages with the square groove in the Y-axis direction, ensuring its stability in that direction. An injection-molded isolation plate abuts and limits the protective block in the Z-axis direction, preventing displacement in that direction.

[0034] A thermal pad 6 is attached to the side of the temperature sensor 7 closest to the battery cell to enhance thermal conduction between the temperature sensor and the battery cell, ensuring accurate temperature detection. The circumferential outer contour of the thermal pad matches the circumferential outer contour of the temperature sensor, maximizing the contact area between the thermal pad and the temperature sensor and improving thermal conduction efficiency.

[0035] like Figure 3 and Figure 4 As shown, in this embodiment, the injection-molded isolation plate 3 is provided with rivet posts 8, and the aluminum bar 1 has a circular hole 11 at the position corresponding to the rivet post. The circular hole 11 and the rivet post 8 are matched and installed to limit the position, thereby fixing the injection-molded isolation plate and the aluminum bar and ensuring a stable connection between the two. The protective block has protrusions 9 on both side walls in the Y-axis direction, and the inner wall of the square groove has a matching groove 10. The protrusions include protrusions or protrusions. The protective block is limited in the Y-axis direction by engaging with the groove.

[0036] This utility model discloses a novel fixed temperature sensor design that eliminates complex structural designs, solves the problem of insufficient design space hindering mass production feasibility, reduces material usage, and features a simple structure, easy mold making, low cost, and convenient product processing. Furthermore, the novel fixed structure's small footprint creates more structural layout space for new energy power battery modules. This design enables weight reduction, cost reduction, and improved reliability of CCS modules, providing effective support for research on lightweighting, cost savings, and reliability of new energy power battery modules.
