Description

Technical Field

[0001] The utility model relates to an aluminum bar fixing structure, in particular to a novel power battery aluminum bar fixing structure and a CCS component. Background Art

[0002] New energy vehicles require large-capacity power batteries, which are usually composed of independent battery cells. Among them, CCS components are an important component of new energy power battery modules. For traditional CCS components, the aluminum bars are usually fixed with movable clips and injection-molded isolation plates. However, the movable clips are highly elastic and easily deformed and unstable, and are prone to breaking or causing the aluminum bar to fall out. Multiple processing is prone to defects. Once the movable clips are deformed or even broken during installation of the aluminum bar, it will cause process losses, resulting in low efficiency and high processing costs in multiple processes. In addition, most conventional aluminum bars on the market today have simple structures and small thicknesses, further exacerbating the problem of easy detachment after installation. Utility Model Content

[0003] In order to solve the deficiencies of the above technologies, the present invention provides a new power battery aluminum bar fixing structure and CCS assembly.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a new type of power battery aluminum bar fixing structure, which includes an injection-molded isolation plate, on which is formed an aluminum bar groove for installing and placing the aluminum bar, and an integrated buckle for fixing the aluminum bar;

[0005] The integrated buckle has a hook structure, and a square hole is opened at the position of the aluminum bar corresponding to the buckle. The aluminum bar is fixed by cooperating with the integrated buckle through the square hole.

[0006] Preferably, the aluminum bar trough is surrounded by raised side walls on the injection-molded isolation plate, and the integrated buckle is located on the side walls of the aluminum bar trough.

[0007] Preferably, an inwardly extending deformation section is formed at one side edge of the side wall of the aluminum bar groove, and an integrated snap-fit is formed at the location of the inwardly extending deformation section.

[0008] Preferably, the length of the integrated buckle is 2 mm, and the opening size of the square hole is 2 mm*3 mm.

[0009] Preferably, a limit block is provided on the side wall of the aluminum bar groove.

[0010] Preferably, the limit block is located at the top corner of the aluminum bar groove and extends along the top of the side wall of the aluminum bar groove.

[0011] Preferably, the injection molded isolation plate is also formed with an anti-fool structure, which is connected to one side of the aluminum trough side wall.

[0012] A CCS component includes a new power battery aluminum bar fixing structure.

[0013] Preferably, the aluminum bar is a laminated aluminum bar, and the square holes are opened in the upper aluminum substrate of the laminated aluminum bar.

[0014] The utility model discloses a new type of power battery aluminum bar fixing structure and CCS assembly. It adopts an injection-molded isolation plate with an integrated snap-on structure, which cooperates with the square hole on the aluminum bar to quickly fix the aluminum bar. Compared with the traditional movable snap-on structure, it is not easy to deform and break, and the fixation is more stable and reliable. At the same time, the limit block is used to strengthen the fixation to prevent the aluminum bar from falling out. The aluminum bar used is a laminated aluminum bar. The laminated aluminum bar structure can be flexibly grooved to avoid the block structure. Compared with the traditional single-layer aluminum bar, the stamping process is omitted, which plays a key role in reducing costs and increasing efficiency. In addition, the traditional single-layer aluminum bar has a small thickness, and the laminated aluminum bar can increase its thickness, reduce the probability of the aluminum bar falling off, and can effectively increase the cross-sectional flow area.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0019] The utility model discloses a new type of power battery aluminum bar fixing structure, the structure is arranged as follows Figure 1 and Figure 2 As shown, it includes an injection molded isolation plate 1 as an insulating structure, and the injection molded isolation plate 1 is used to fix and limit the aluminum bar 2.

[0020] First, an aluminum bar groove 3 for installing and placing the aluminum bar 2 is formed on the injection molded isolation plate 1. Secondly, an integrated clip 4 is also integrally provided on the injection molded isolation plate 1; the integrated clip 4 has a hook structure, and accordingly, a square hole 5 is opened at the position of the aluminum bar 2 corresponding to the clip 4. Therefore, after the aluminum bar 2 is installed and placed in the aluminum bar groove 3, it is fixed through the square hole 5 and the integrated clip 4, thereby realizing rapid fixation of the aluminum bar.

[0021] As for the integrated buckle 4, it is an integrated structure on the injection molded isolation plate 1; preferably, the aluminum groove 3 is surrounded by the raised side walls on the injection molded isolation plate 1, and the side walls of the aluminum groove 3 provide a location for the setting of the integrated buckle 4.

[0022] In order to make the integrated buckle 4 smoothly combine with the square hole 5 on the aluminum bar 2, an inward deformation section 8 is formed on one side of the side wall of the aluminum bar groove 3, and the integrated buckle 4 is integrally formed at the location of the inward deformation section 8.

[0023] Thus, the novel design can replace the movable clips of traditional injection molded isolation panels by opening a hole in the aluminum bar 2 and using an integrated clip, which reduces the processing difficulty and has the advantage of being less prone to deformation and breakage. Preferably, the length of the integrated clip 4 is set to 2mm, and the size of the square hole 5 is 2mm*3mm.

[0024] In order to further improve the stability of the aluminum bar 2 fixed in the aluminum bar groove 3, a limit block 6 is further provided on the side wall of the aluminum bar groove 3. The limit block 6 is located at the top corner position of the aluminum bar groove 3 and extends along the top end of the side wall of the aluminum bar groove 3. According to the limiting requirements, one or more top corner positions can be arbitrarily selected to set the limit block.

[0025] In addition, an anti-fool structure 7 is formed on the injection molded isolation plate 1. The anti-fool structure 7 is connected to one side of the side wall of the aluminum bar groove 3. The anti-fool structure 7 designed with a specific shape helps to distinguish and avoid incorrect installation of the aluminum bar.

[0026] The present utility model also discloses a CCS component, which adopts a new power battery aluminum bar fixing structure designed by the present utility model. The square hole on the aluminum bar 2 is fixed with the integrated buckle 4 of the injection-molded isolation plate 1, and the aluminum bar 2 is fixed in the aluminum bar groove 3 of the injection-molded isolation plate 1 by using a limit block 6.

[0027] Preferably, the aluminum bar 2 is a laminated aluminum bar, and the square hole 5 is opened at the upper aluminum substrate of the laminated aluminum bar; the laminated aluminum bar has an increased thickness compared to the traditional single-layer aluminum bar, thereby reducing the probability of the aluminum bar falling off.

[0028] At the same time, the laminated aluminum bar can be flexibly grooved to avoid the block structure. Compared with the traditional single-layer aluminum bar, it eliminates the stamping process and, to a certain extent, avoids the defective phenomenon of the one-piece clip after multiple processing. The laminated aluminum bar can also increase the flow area and improve the stress that the battery cell can withstand after expansion, which plays a key role in improving production efficiency.

[0029] The above-mentioned implementation manner is not a limitation of the present invention, and the present invention is not limited to the above-mentioned examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also fall within the scope of protection of the present invention.
