Description

Technical Field

[0001] This utility model relates to the field of new energy battery module technology, and in particular to an integrated CCS sampling module that is easy to assemble. Background Technology

[0002] In new energy battery modules, the CCS (Cell Contact System) sampling module is a core component for battery state monitoring. The stability and assembly efficiency of its wiring harness directly affect product safety and production costs. Traditional sampling harness fixing methods rely on multiple independent cable ties to bundle and fix them one by one, which has significant drawbacks:

[0003] Low space utilization: Multiple independent cable ties occupy a large amount of space in the wire harness slot, resulting in a messy wire harness layout, which not only affects the neatness of the appearance, but also hinders the integration design of subsequent module heat dissipation structures or other functional components.

[0004] The assembly process is cumbersome: the repeated cable tie fixing operation requires manual or robotic arms to repeatedly position, thread, and lock, which greatly increases the assembly time. In addition, the frequent friction and collision between the wire harness and the cable tie during the operation can easily cause hidden damage such as wear on the wire insulation layer and scratches on the metal wires.

[0005] Accumulated quality risks: Each cable tie fixing step may introduce assembly errors (such as cable ties being too tight and compressing the wire harness, or too loose and causing displacement). The accumulation of multiple processing steps significantly increases the product defect rate, which violates the manufacturing principle of "reducing one processing step reduces one point of risk".

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] like Figures 1 to 5 As shown, this application provides an integrated CCS sampling module that is easy to assemble, including: a blister box 10 for supporting a battery module; an adapter slot 11 opened on one side of the blister box 10, with buckles 12 staggered at the edge of the opening of the adapter slot 11; a wire harness 50 laid inside the adapter slot 11, with a sampling terminal 30 connected to the outside of the wire harness 50 by a wire; and a pressure strip 40 pressing between the wire harness 50 and the buckles 12.

[0032] After adopting the above technical solution, by setting the pressure strip 40 in the middle of the blister box 10 and the wire harness 50, the problem of multiple cable ties occupying a large amount of space in the wire harness slot during the installation and fixing process of the existing CCS sampling module can be solved. This results in a messy wire harness layout, which not only affects the appearance and regularity, but also hinders the integration design of the subsequent module heat dissipation structure or other functional components. The repeated cable tie fixing operation requires manual or robotic arms to repeatedly position, thread, and lock, which greatly increases the assembly time. In addition, the frequent friction and collision between the wire harness and the cable tie during the operation can easily cause hidden damage such as wear of the wire insulation layer and scratches on the metal wires.

[0033] It should be noted that during the installation of the wire harness 50, after the aluminum busbar 20, the acquisition terminal 30 and the wire harness 50 are assembled, the wire harness 50 is ensured to be located inside the blister box 10. The pressure strip 40 is quickly pushed into the adapter groove 11 along the buckle 12. Under the natural force, the upward pushing force of the pressure strip 40 and the downward force of the buckle 12 are opposite in direction and the same in magnitude, forming a dynamic balance and achieving the fixing effect. This reduces the efficiency reduction caused by manual binding and tying, and plays a role in increasing production and efficiency.

[0034] During the process of the pressure strip 40 passing through the buckle 12, the above operation can be performed by an automated robotic arm. Then, the interaction force of the wire harness 50, the pressure strip 40 and the buckle 12 can be used to fix the entire module.

[0035] In a preferred and feasible embodiment, the pressure strip 40 is made of PC (polycarbonate) material. When implementing this embodiment, given the PC material of the pressure strip 40, its excellent high-temperature resistance plays a crucial role during the insertion process between the wire harness 50 and the clip 12. (See attached diagram.) Figure 6 Further analysis reveals that the PC material can withstand temperatures exceeding 130℃. This characteristic ensures that after the blister pack 10 and battery module are assembled, it not only fully meets the various operating conditions required by the battery during daily use but also easily handles the heat generated by the wiring harness 50 during operation. Thanks to the excellent high-temperature resistance of the PC material, problems such as material aging and deformation caused by high temperatures are effectively avoided, thus significantly improving the service life of the pressure strip 40 and providing a reliable guarantee for the stable operation of the entire battery system.

[0036] In another equally innovative and practical embodiment, the pressure strip 40 is made of PPSU (polyphenylsulfone). In implementing this embodiment, the unique chemical properties of PPSU material become apparent. Because PPSU is resistant to weak acids, weak alkalis, and neutral oils, it can adapt to certain complex environments during daily battery use. For example, in environments where it may come into contact with trace amounts of acidic or alkaline substances or neutral oils, the PPSU pressure strip 40 can still maintain stable performance and will not be damaged by chemical corrosion, thereby further improving the practicality and reliability of the entire battery module and broadening its application range.

[0037] In another optional embodiment, this application also includes an aluminum busbar 20 connected to the acquisition terminal 30. The aluminum busbar 20 is arranged in a carefully designed staggered pattern along the outer side of the wiring harness 50. This unique distribution is not arbitrary but the result of in-depth research and optimization design. This layout of the aluminum busbar 20 greatly facilitates its connection with the acquisition terminal 30. Through this connection method, the acquisition terminal 30 can stably and accurately acquire various key data of the battery module, such as voltage, current, and temperature. Based on this real-time acquired data, real-time monitoring of the battery module can be achieved, like equipping the battery module with a sensitive "health monitor." Once any abnormality occurs in the battery module, such as overcharging, over-discharging, or abnormal temperature, the background system can immediately issue an alarm, and relevant personnel can take timely measures to handle the situation, effectively preventing the occurrence of emergencies, ensuring the safe operation of the battery module, and extending the service life of the battery module.

[0038] In another optional embodiment, the upper end of the blister box 10 is precision-machined to have a slot specifically for holding the aluminum strip 20. The slot is not a simple groove structure; it also cleverly incorporates positioning posts that engage with the aluminum strip 20. During the fitting and installation operation between the aluminum strip 20 and the blister box 10, corresponding positioning holes are provided on the top of the aluminum strip 20. During installation, simply align the positioning holes of the aluminum strip 20 with the positioning posts in the slot and insert them to achieve a secure connection between the aluminum strip 20 and the blister box 10. This connection method is not only convenient and quick to install, but also ensures that the aluminum strip 20 is accurately positioned on one side of the blister box 10, preventing loosening or displacement of the aluminum strip 20 during use, thus ensuring the stability and reliability of the entire structure.

[0039] In another optional embodiment, the buckle 12 and the adapter slot 11 are fixedly connected. This connection method has been rigorously designed and tested to ensure the connection strength and stability between the two. Simultaneously, one edge of the buckle 12 is finely polished and chamfered. When implementing this embodiment, when the pressure strip 40 is inserted between the wire harness 50 and the buckle 12, due to the chamfer, the pressure strip 40 can smoothly slide into the adapter slot 11 at an angle. This design effectively avoids problems such as jamming or damage caused by hard collisions between the pressure strip 40 and the edge during insertion, ensuring smooth connection between the pressure strip 40, the wire harness 50, and the buckle 12, and improving the efficiency and quality of the entire assembly process.
