[0051] 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, and 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 scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0052] According to a first aspect of the present invention, referring to... Figures 1 to 3This utility model embodiment provides an isolation component 2 for a busbar 1, including: a first connecting structure 21, which is used to snap onto the busbar 1 so that the isolation component 2 is fixed to the busbar 1; and a second connecting structure 22, which is connected to the first connecting structure 21 and is used to support and fix the insulating cover 3 of the battery cell module 4.

[0053] In use, the first connecting structure 21 can be connected to the busbar 1 first, so that the isolator 2 is fixed on the busbar 1. Then the insulating cover 3 and the second connecting structure 22 can be connected to fix the relative position between the busbar 1 and the insulating cover 3.

[0054] The first connecting structure 21 is connected to the busbar 1 by a snap-fit ​​mechanism, which provides a certain connection strength and facilitates the installation and disassembly of the first connecting structure 21 and the busbar 1, thereby reducing the difficulty of operation for workers. There are several ways to snap-fit ​​the first connecting structure 21 to the busbar 1. For example, a groove can be made on the busbar 1, and the first connecting structure 21 can be set as a protrusion that mates with the groove; inserting the protrusion into the groove achieves the snap-fit. Alternatively, a through hole 311 can be made on the busbar 1, and the first connecting structure 21 can be set as a snap-fit; the snap-fit ​​and the through hole 311 mate to achieve the snap-fit. The first connecting structure 21 can also be directly set as a gripper structure, allowing the isolator 2 to be directly clamped onto the busbar 1. Other forms can also be used to achieve the snap-fit ​​between the first connecting structure 21 and the busbar 1; this invention does not limit this approach.

[0055] The second connecting structure 22 is used to connect the insulating cover 3, and the connection method between the two can be selected according to design requirements. For example, the second connecting structure 22 can be configured as an adhesive layer, allowing the insulating cover 3 to be adhered to the spacer 2; alternatively, a through hole 311 can be provided on the insulating cover 3, and the second connecting structure 22 can be configured as a protrusion that can be inserted into the through hole 311, allowing the insulating cover 3 to snap into the spacer 2; alternatively, a threaded hole can be provided on the insulating cover 3, and the second connecting structure 22 can be configured as another threaded hole opposite to it, allowing the insulating cover 3 and the spacer 2 to be connected by bolts; alternatively, a magnetic element can be provided on the insulating cover 3, in which case the second connecting structure 22 can be configured as a magnetically attracted metal or another magnetic element, allowing a magnetic connection between the insulating cover 3 and the spacer 2. Other forms can also be used to achieve the connection between the second connecting structure 22 and the insulating cover 3, and this utility model does not limit this.

[0056] The first connecting structure 21 and the second connecting structure 22 can be made of plastic materials such as polyamide 66, polycarbonate, polyphenylene ether, high-density polyethylene, and acrylonitrile-butadiene-styrene copolymer. These materials have high strength, excellent impact resistance and insulation properties, ensuring the firmness of the connection while having a small weight, thereby minimizing the weight of the battery pack.

[0057] In this embodiment of the invention, a first connecting structure 21 and a second connecting structure 22 are respectively provided on the separator 2. The separator 2 can be directly snapped onto the busbar 1 through the first connecting structure 21, and then the insulating cover 3 can be supported and fixed through the second connecting structure 22, thereby fixing the relative position between the insulating cover 3 and the busbar 1. Compared with the method of connecting by cable ties, the installation of the insulating cover 3 is simpler in this invention, which greatly improves the assembly efficiency of the battery module. Moreover, cable ties have certain requirements for flexibility and their flame retardancy rating is low, usually only reaching UL94-V2, while the separator 2 in this invention can be made of materials such as polycarbonate that meet the UL94-V0 requirements, which greatly enhances the flame retardancy performance of the battery pack.

[0058] In one embodiment, reference is made to Figure 2 and Figure 5 The isolation member 2 also includes a connecting portion 23; the first connecting structure 21 includes: a first limiting member 211, which is connected to the connecting portion 23; and a second limiting member 212, which is connected to the connecting portion 23. The first limiting member 211 and the second limiting member 212 are spaced apart so that a first slot 213 is formed between the first limiting member 211 and the second limiting member 212. The first slot 213 is used to connect with the busbar 1.

[0059] By engaging the busbar 1 through the first slot 213, the isolator 2 can be fixed onto the busbar 1. Depending on the specific structure of the first limiting member 211 and the second limiting member 212, the first slot 213 can have only one opening or multiple openings. For example, when the connecting part 23 is a vertical plate, the first limiting member 211 and the second limiting member 212 can be set as parallel horizontal plates, with the vertical plate and the horizontal plate perpendicular to each other. In this case, the enclosed first slot 213 has openings on three sides, allowing the operator to choose the insertion method of the busbar 1 and the isolator 2 as needed. Alternatively, the first limiting member 211 and the second limiting member 212 can be set as L-shaped plates, so that the enclosed first slot 213 has only one opening. In this case, the L-shaped plate is connected to the peripheral side of the busbar 1, thereby improving the stability of the connection between the busbar 1 and the isolator 2.

[0060] The number of the first limiting member 211 and the second limiting member 212 can be set as needed. For example, both the first limiting member 211 and the second limiting member 212 can include multiple spaced limiting blocks, so that the busbar 1 can be inserted between the limiting blocks while reducing the material used for the isolation member 2, thereby reducing the weight of the isolation member 2 and saving costs. The distance between the first limiting member 211 and the second limiting member 212 is related to the size of the busbar 1. Usually, the size of the first slot 213 needs to be slightly smaller than the size of the busbar 1 so that the first slot 213 can firmly clamp the busbar 1.

[0061] In one embodiment, reference is made to Figure 5 and Figure 6 The first limiting member 211 is provided with a locking hook 2111, and a second slot 214 is formed between the locking hook 2111 and the second connecting structure 22. The second slot 214 is used to engage the busbar 1.

[0062] The locking hook portion 2111 and the second connecting structure 22 are spaced apart. Taking the locking hook portion 2111 and the second connecting structure 22 as being arranged along the X-axis direction as an example, when the busbar 1 is engaged in the first slot 213, one side of the busbar 1 is restricted by the locking hook portion 2111, and the other side of the busbar 1 is restricted by the second connecting structure 22, thereby fixing the position of the busbar 1 and the isolator 2 in the X direction, and further improving the stability of the connection between the busbar 1 and the isolator 2.

[0063] In some embodiments, the locking hook portion 2111 is set as a protrusion on the first limiting member 211, and the distance between the locking hook portion 2111 and the second connecting structure 22 is controlled to be close to the width of the busbar 1, so that both the locking hook portion 2111 and the second connecting structure 22 abut against the busbar 1, thereby improving the limiting effect on the busbar 1 and enabling the isolation member 2 to be firmly fixed on the busbar 1.

[0064] In some embodiments, the surface of the locking hook 2111 that contacts the busbar 1 is a plane, which makes the contact area between the locking hook 2111 and the busbar 1 larger, thereby increasing the friction between the two and thus improving the stability of the engagement between the second slot 214 and the busbar 1.

[0065] In one embodiment, reference is made to Figure 5 and Figure 6The first limiting member 211 is elongated, with one end of the first limiting member 211 away from the second connecting structure 22 and having a locking hook portion 2111. The first slot 213 near the locking hook portion 2111 forms an insertion interface 215 for the busbar 1 to be inserted. The end of the locking hook portion 2111 away from the second connecting structure 22 and / or the end of the second limiting member 212 away from the second connecting structure 22 are provided with a guide structure 21111 to guide the busbar 1 into the first slot 213.

[0066] It should be noted that in the embodiments of this application, "and / or" describes the relationship between associated objects, indicating that there can be three kinds of relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0067] The isolator 2 is typically made of high-strength plastic, and the first limiting member 211 is elongated, giving it a certain degree of elasticity. When the busbar 1 is slowly inserted into the first slot 213 from the side of the hook portion 2111, the guide structure 21111 first guides the busbar 1 into the first slot 213, reducing the difficulty of operation for the operator. Then, because the busbar 1 is slightly larger than the first slot 213, the elongated first limiting member 211 deforms, allowing the busbar 1 to be smoothly inserted into the first slot 213. After the busbar 1 is accommodated in the first slot 213, the deformed first limiting member 211 also provides a certain amount of pressure, ensuring a tight connection between the busbar 1 and the isolator 2. Specifically, the width of the first limiting member 211 can be set as needed. A larger width provides stronger resistance to deformation and a more secure connection between the busbar and the isolator 2; a smaller width makes it easier for the busbar 1 to engage with the first slot 213.

[0068] The guide structure 21111 can be configured as an inclined surface that is tilted toward the inside of the first slot 213, so that when the busbar 1 is inserted, the edge of the busbar 1 first contacts the inclined surface, and as the busbar 1 continues to be inserted, the inclined surface will guide the busbar 1 to gradually enter the first slot 213.

[0069] In one embodiment, reference is made to Figure 6 and Figure 7 The connecting part 23 includes a partition 231, and a first connecting structure 21 is provided on each side of the thickness direction H2 of the partition. The first connecting structures 21 located on different sides of the partition 231 are used to connect to different busbars 1.

[0070] Since multiple busbars 1 are typically spaced apart in the battery cell module 4, in this embodiment of the invention, a first connection structure 21 is provided on both sides of the partition 231, enabling the isolator 2 to connect to two busbars 1 simultaneously, further improving the stability of the connection between the isolator 2 and the busbar 1. Furthermore, after the isolator 2 is installed on the busbar 1, the partition 231 is located between the two busbars 1, which increases the creepage distance between the busbars 1 and improves the safety performance of the battery cell module 4.

[0071] In one embodiment, reference is made to Figure 6 and Figure 7 The connecting part 23 also includes a connecting plate 232, which is connected to the partition plate 231, and the second connecting structure 22 is connected to the connecting plate 232.

[0072] The connection plate 232 allows for more flexible placement of the second connection structure 22. The position of the second connection structure 22 can be changed by altering the size of the connection plate 232 and the connection angle between the connection plate 232 and the partition plate 231, thus adapting to different models of insulating covers 3. For example, in some embodiments, the insulating cover 3 is a regular rectangle. In this case, the connection plate 232 can be perpendicularly connected to the partition plate 231, allowing multiple separators 2 to be used in a single cell module 4. In this case, the second connection structures 22 are neatly arranged and can be connected to the insulating cover 3 simultaneously, thereby improving the stability of the connection between the separators 2 and the insulating cover 3.

[0073] In one embodiment, reference is made to Figures 4 to 6 The first limiting member 211 is connected to the connecting plate 232, and the second limiting member 212 is connected to the partition 231; the connecting plate 232 is connected to one end of the partition in the length direction H3, and the first limiting member 211 and the second limiting member 212 are spaced apart along the width direction H4 of the partition.

[0074] The first limiting member 211 and the second limiting member 212, arranged along the width direction of the partition 231, can clamp the busbar 1, thereby restricting the movement of the busbar 1 in the width direction of the partition 231. The first limiting member 211 is connected to the connecting plate 232, creating a certain gap between the first limiting member 211 and the partition 231. When the busbar 1 is inserted into the first slot 213, the first limiting member 211 can deform, making insertion of the busbar 1 easier. The second limiting member 212, located on the partition 231, ensures that the second limiting member 212 is difficult to deform, ensuring that the first slot 213 can provide sufficient pressure to clamp the busbar 1 and guarantee the stability of the connection.

[0075] In one embodiment, reference is made to Figure 7 and Figure 8The second connecting structure 22 includes a third limiting member 221, which protrudes from the connecting part 23 and is used to engage with the through hole 311 of the side wall 31 of the insulating cover 3.

[0076] The insulating cover 3 typically has a side wall 31 to prevent the busbar 1 from being exposed. This also prevents contamination of the busbar 1 by debris or dust during assembly and transfer, and prevents short circuits and fires caused by operator error leading to contact with the busbar 1. A through hole 311 is provided on the side wall 31 to facilitate the passage of cable ties for locking the insulating cover 3. Based on this, in this embodiment of the invention, a third limiting member 221 is provided so that when the insulating cover 3 is installed on the isolator 2, the third limiting member 221 can engage with the through hole 311, thereby achieving a locking between the isolator 2 and the insulating cover 3.

[0077] In some embodiments, the third limiting member 221 can be configured as a pin, which can be directly inserted into the through hole 311, resulting in a simple structure and low manufacturing cost. Alternatively, the third limiting member 221 can be configured as a ring-shaped buckle, consisting of two hinged semicircular parts. When the buckle is open, the insulating cover 3 can be installed; when the buckle is closed, the semicircular parts can pass through the through hole 311 to achieve locking, thereby preventing compression between the insulating cover 3 and the insulating cover 3 and reducing the probability of damage to the insulating cover 3 or the isolator 2. By setting the third limiting member 221, the movement of the insulating cover 3 in any direction on the plane of its side wall 31 can be restricted, improving the stability of the connection between the insulating cover 3 and the isolator 2.

[0078] In one embodiment, reference is made to Figure 7 and Figure 8 The third limiting member 221 has a guide surface 2211 at one end facing away from the connecting part 23. During installation, the insulating cover 3 first contacts the guide surface 2211. Then, as the insulating cover 3 descends, it presses against the third limiting member 221 until the third limiting structure is engaged within the through hole 311. By providing the guide surface 2211, the insulating cover 3 can smoothly engage with the isolating member 2 along the guide surface 2211 during installation, reducing resistance during installation and making the installation of the insulating cover 3 easier.

[0079] In one embodiment, reference is made to Figure 7 and Figure 8 The second connecting structure 22 also includes a fourth limiting member 222, which is connected to the connecting part 23. The fourth limiting member 222 is provided with a limiting groove 2221 with an opening facing the insulating cover 3, for accommodating the side wall 31 of the insulating cover 3.

[0080] When the insulating cover 3 is installed, it is inserted into the limiting groove 2221 from the opening, thereby restricting the horizontal movement of the insulating cover 3. In some embodiments, the width of the limiting groove 2221 is slightly smaller than the thickness of the side wall 31 of the insulating cover 3, so that the limiting groove 2221 and the insulating cover 3 achieve an interference fit, improving the stability of the connection between the isolator 2 and the insulating cover 3.

[0081] In one embodiment, reference is made to Figure 7 The main body is provided with a support part 24, which is used to support the insulating cover 3.

[0082] The support portion 24 can be columnar, plate-shaped, or other irregularly shaped, and this embodiment of the present invention does not limit this. By providing the support portion 24, after the insulating cover 3 is installed on the isolation member 2, the support portion 24 abuts against the inner surface of the insulating cover 3, thereby supporting the insulating cover 3 and improving the structural stability of the battery cell module 4.

[0083] According to a second aspect of this utility model, a battery cell module 4 is provided, comprising: a plurality of battery cells; a busbar 1 connected to the battery cells; an isolator 2 as described in the foregoing embodiments, the isolator 2 being snapped into the busbar 1; and an insulating cover 3 connected to the isolator 2. Since the battery cell module 4 includes the aforementioned busbar 1, it possesses all the beneficial effects of the aforementioned busbar 1, and the embodiments of this utility model will not be described in detail here.

[0084] According to a third aspect of this utility model, a battery pack is provided, including the cell module 4 in the foregoing embodiments. Since the battery pack includes the aforementioned cell module 4, it possesses all the beneficial effects of the aforementioned cell module 4; further details of the embodiments of this utility model will not be repeated here.

[0085] According to a fourth aspect of this utility model, a vehicle is provided, including the cell module 4 or the battery pack as described in the foregoing embodiments. Since the vehicle includes the aforementioned cell module 4 or battery pack, it possesses all the beneficial effects of the aforementioned cell module 4 or battery pack, which will not be elaborated upon here. The vehicle may be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this application does not specifically limit its application in this regard.
