Description

Technical Field

[0001] This utility model relates to the field of battery pack technology, and in particular to a CCS component structure with a protective cover. Background Technology

[0002] New energy vehicles have received widespread attention from all sectors of society due to their excellent environmental performance, and the requirements for them are constantly increasing. As a type of new energy vehicle, electric vehicles are also developing towards higher safety, higher energy density, and lighter weight. The main factor determining the driving range of an electric vehicle is the power supply battery. Different specifications of power supply batteries can be selected for different vehicle models to meet driving requirements.

[0003] Battery packs used in electric vehicles typically consist of multiple cell modules connected in series. This means that multiple cell modules are horizontally stacked within the same housing and then connected in series. The core cell module is configured with a specific number of cells to meet the required output voltage, and all the cells are connected via copper busbars to output the voltage.

[0004] In power battery cell modules, the positive and negative terminals of the battery cells are positioned upwards and symmetrically arranged on the cell surface. Voltage is typically acquired using wiring harnesses. However, traditional wiring harness acquisition requires multiple harnesses, which not only occupies a large space in the battery pack but also relies heavily on manual labor during electrical connections, resulting in very low automation. Therefore, the integrated busbar CCS module was developed as a key electrical connection structure within the battery module, with main functions including:

[0005] High-voltage series and parallel connection of battery cells: This enables high-voltage series and parallel connection of battery cells in the battery module, ensuring that the battery system can operate normally.

[0006] Information Acquisition: Integrates signal acquisition components (such as FPC, FFC, etc.) to collect information such as battery temperature and voltage, providing important data support for BMS (Battery Management System).

[0007] Safety protection: It has an overcurrent fuse function, which can quickly cut off the current when the battery system malfunctions, preventing the fault from escalating.

[0008] Chinese utility model patent CN220155717U discloses a CCS assembly, which includes a wire harness, a conductive busbar electrically connected to the wire harness, and a mounting bracket for mounting the conductive busbar. The mounting bracket is an epoxy board, and the conductive busbar is fixed to the mounting bracket by fasteners. In this design, because there is no mounting position on the mounting bracket for quick positioning of the conductive busbar, position calibration is time-consuming. Furthermore, the use of screws or rivets as fasteners between the conductive busbar and the mounting bracket (which can also be understood as a wire harness isolation plate) further increases the complexity of the connection between the conductive busbar and the mounting bracket. Disassembly of the conductive busbar in case of a fault is also cumbersome.

[0009] On the other hand, since the conductive busbar (also known as the conductive aluminum busbar) has a conductive function, if it is directly exposed to the air, it will inevitably cause a short circuit in the battery cell when it comes into contact with an external conductor or liquid, which will lead to a safety accident.

[0010] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0011] The purpose of this invention is to overcome the problems of the prior art and provide a CCS component structure with a protective cover. This solves the technical problems of the inability to quickly position and connect the conductive aluminum bar and the wire harness isolation plate in the traditional technology, and the fact that exposing the conductive aluminum bar to the air will inevitably cause a short circuit in the battery cell when it comes into contact with external conductors or liquids, thus leading to a safety accident.

[0012] The above objectives are achieved through the following technical solutions:

[0013] A CCS assembly structure with a cover includes a wire harness isolation plate and a matching cover. The wire harness isolation plate has a flexible circuit board mounting position at its axial position for mounting a flexible circuit board, and symmetrically arranged on both sides of the flexible circuit board mounting position are a left aluminum bar mounting position and a right aluminum bar mounting position for mounting conductive aluminum bars. Each of the left and right aluminum bar mounting positions has an aluminum bar mounting frame with a hollowed-out bottom, and several aluminum bar support beams are provided at the bottom of the aluminum bar mounting frame. The inner wall of the aluminum bar mounting frame is provided with aluminum bar buckles. The outer side of the aluminum bar mounting frame is provided with cover clips, and correspondingly, the cover has a matching cover slot.

[0014] Furthermore, the aluminum bar mounting frame has a nickel strip through groove on the side facing the flexible circuit board mounting position, so as to electrically connect the conductive aluminum bar to the flexible circuit board through the nickel strip.

[0015] Further, in the left aluminum bar mounting position, the aluminum bar mounting frame includes a front external aluminum bar mounting frame arranged sequentially from front to back, and a plurality of left aluminum bar mounting frames; in the right aluminum bar mounting position, the aluminum bar mounting frame includes a rear external aluminum bar mounting frame arranged sequentially from back to front, and a plurality of right aluminum bar mounting frames; the conductive aluminum bar includes a front external aluminum bar installed in the front external aluminum bar mounting frame, a left conductive aluminum bar installed in the left aluminum bar mounting frame, a rear external aluminum bar installed in the rear external aluminum bar mounting frame, and a right conductive aluminum bar installed in the right aluminum bar mounting frame.

[0016] Furthermore, the number of the left aluminum bar mounting frames is the same as the number of the right aluminum bar mounting frames.

[0017] Furthermore, the front-end external aluminum bar mounting frame and the rear-end external aluminum bar mounting frame have the same specifications, and both have external through slots on the side facing the end.

[0018] Furthermore, external aluminum bar mounting frames at the front and rear ends are provided with external aluminum bar clips on the inner walls of the sides facing the flexible circuit board mounting positions, and external aluminum bar buckles are provided on the other side corresponding to the external aluminum bar clips.

[0019] Furthermore, the left and right aluminum bar mounting frames have the same specifications, both including symmetrically arranged front and rear borders, as well as symmetrically arranged inner and outer borders; the aluminum bar buckles include a front aluminum bar buckle disposed on the inner wall of the front border and a rear aluminum bar buckle disposed on the inner wall of the rear border; an aluminum bar buckle block is disposed on the inner wall of the inner border.

[0020] Furthermore, there are three of each of the left and right aluminum bar mounting frames.

[0021] Furthermore, a plurality of positioning posts are provided on the flexible circuit board mounting position, and corresponding positioning holes are provided on the flexible circuit board that correspond to the positioning posts.

[0022] Furthermore, the wire harness isolation plate is made of insulating material.

[0023] This utility model provides a CCS assembly structure with a protective cover. By setting aluminum bar mounting frames at the left and right aluminum bar mounting positions and aluminum bar buckles on the inner walls of the mounting frames, it achieves precise positioning and locking of the conductive aluminum bar. Furthermore, by setting protective cover feet on the outer side of the aluminum bar mounting frames and providing matching protective cover grooves on the cover, it can shield each mounting position, thus isolating it from the outside and protecting the internal conductive aluminum bar and flexible circuit board components. This CCS assembly structure is not only simple in structure but also enables rapid positioning and installation of the conductive aluminum bar and flexible circuit board while providing protection.

[0041] like Figures 1-4 As shown, this solution provides a CCS assembly structure with a cover, including a wire harness isolation plate 1 and a matching cover 2.

Figure 5 As shown.

[0043] The outer side of the aluminum bar mounting frame 5 is provided with a cover clip 506, and the cover 2 is provided with a matching cover slot 201. By engaging the cover clip 506 with the cover slot 201, the cover 2 can be quickly snapped onto the wire harness isolation plate 1, thereby protecting the conductive aluminum bar 4 and the flexible circuit board 3 installed on the wire harness isolation plate 1.

[0044] It should be noted that the wire harness isolation plate 1 is made of insulating material, such as plastic.

[0047] In the right aluminum bar mounting position 103, the aluminum bar mounting frame 5 includes a rear external aluminum bar mounting frame 502 arranged sequentially from back to front, and a plurality of right aluminum bar mounting frames 504.

[0052] The front-end external aluminum bar mounting frame 501 and the rear-end external aluminum bar mounting frame 502 have the same specifications, and both have external through slots 507 on their sides facing the ends.

[0053] Specifically, the front-end external aluminum bar 401 extends out of the external through slot 507 and connects to the external copper busbar 10;

[0057] As a specific embodiment of this solution, the front external aluminum bar 401 is inserted obliquely into the front external aluminum bar mounting frame 501 until it is stopped by the external aluminum bar locking block 508; then the front external aluminum bar 401 is pressed down flat until it is locked by the external aluminum bar buckle 509, thus embedding the front external aluminum bar 401 into the front external aluminum bar mounting frame 501.

[0058] The left aluminum bar mounting frame 503 and the right aluminum bar mounting frame 504 described in this solution have the same specifications, both including a symmetrically arranged front frame 510 and rear frame 511, as well as a symmetrically arranged inner frame 512 and outer frame 513.

[0060] An aluminum bac 614 is provided on the inner wall of the inner frame 512.

[0061] The outer frame 513 is provided with the cover clip 506.

[0062] In this embodiment, the interaction between the aluminum bar clip 514, the front aluminum bar clip 601, and the rear aluminum bar clip 602 enables the limiting clip of the left conductive aluminum bar 403 or the right conductive aluminum bar 404, thereby allowing it to be securely embedded in the left aluminum bar mounting frame 503 or the right aluminum bar mounting frame 504.

[0063] As a specific embodiment of this solution, there are three left aluminum bar mounting frames 503 and three right aluminum bar mounting frames 504.
