Description

Technical Field

[0001] The utility model relates to the technical field of battery installation, in particular to an anti-misassembly mechanism for installing copper bars of a battery cluster. Background Art

[0002] In the energy storage field, a battery cluster is a high-voltage battery pack formed by connecting multiple battery packs in series using copper bars. Generally, the battery packs in the battery cluster are arranged in multiple columns. The battery packs need to be connected in series not only with the next battery pack in the same column but also in parallel with the battery packs in adjacent columns. The copper bars are the wires connecting between the battery packs. Therefore, the installation process of the copper bars is crucial for the safe operation of the entire energy storage system.

[0003] Therefore, when manually connecting battery packs and copper bars traditionally, due to the lack of effective positioning and fixing measures, the copper bars are prone to dislocation during the installation process, resulting in poor contact between adjacent battery packs. And if the series and parallel copper bars are wrongly connected manually, it will cause faults in the entire battery cluster.

[0004] In addition, if the copper bars are not installed properly, especially when the gap between the battery packs is small, the upper and lower layer copper bars may come into direct contact, causing a short circuit. Since the voltage of the battery cluster is as high as 1500V, once a short circuit occurs, it will not only cause equipment damage but also may lead to serious accidents such as fire or explosion. And the operator may install the copper bars wrongly due to unfamiliarity with the installation process or negligence.

[0005] In addition, when installing the copper bars, the operator also needs to spend more time to confirm the installation position of the copper bars, which will reduce the installation efficiency.

[0006] Chinese Patent (CN113113713B) discloses a power battery assembly and a vehicle. In this document, a cross beam is used to separate the battery packs. However, since the cross beam cannot be removed or unloaded, it will cause an increase in the overall weight of the battery assembly, affecting the battery quality.

[0007] Therefore, we propose a mechanism that can ensure the correct installation position of the copper bars. Summary of the Utility Model

[0008] In order to overcome the deficiencies in the background art, the utility model discloses an anti-misassembly mechanism for installing copper bars of a battery cluster.

[0009] To achieve the above-mentioned invention purpose, the utility model adopts the following technical scheme:

[0010] An anti-misassembly mechanism for installing copper bars of a battery cluster includes a separating part and a baffle part. The separating part is installed between two adjacent battery packs, and the baffle part is located on the top surface of the separating part and correspondingly above the battery packs.

[0011] Preferably, the separating part includes a central plate and separating strips, wherein a plurality of separating strips are fixedly arranged on both side plates of the central plate, and the separating strips are in contact with the side surfaces of the corresponding battery packs.

[0012] Preferably, two separating strips are arranged on both side plates of the central plate.

[0013] Preferably, a limiting cover is arranged between the separating part and the baffle part, and the limiting cover is located on the top surface of the battery pack.

[0014] Preferably, the limiting cover is arc-shaped.

[0015] Preferably, both the separating part and the baffle part are of multi-section structures, and a docking component is arranged between adjacent separating parts.

[0016] Preferably, the docking component includes a permanent magnet and a magnetic attraction block, wherein the permanent magnet is located on both side surfaces of a certain section of the separating part, and the magnetic attraction block is located on both side surfaces of another section of the separating part.

[0017] Due to the adoption of the technical scheme as described above, the utility model has the following beneficial effects:

[0018] An anti-misassembly mechanism for copper busbar installation of a battery cluster disclosed by the utility model, by being placed between two battery packs, can not only ensure that the distances between adjacent battery packs are the same, which is beneficial to the positioning and fixing during copper busbar installation; and due to the function of the baffle part, the space between the series copper busbars and the parallel copper busbars of the battery packs is blocked, thereby effectively eliminating the possibility of misconnection between the series copper busbars and the parallel copper busbars, and further ensuring that the copper busbars can be in the correct installation positions;

[0019] In addition, by setting the separating part and the baffle part as multi-section structures, the length of the anti-misassembly mechanism can be flexibly adjusted as needed, so as to adapt to different specifications of battery packs, and avoid affecting the installation between battery packs due to the overlong length of the anti-misassembly mechanism.

[0025] The technical solution of the present utility model will be described below in conjunction with the accompanying drawings in the embodiments of the present utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right", etc. indicating the orientation or positional relationship, they are only corresponding to the accompanying drawings of the present utility model for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation:

[0026] Embodiment 1 is as follows:

[0027] Combined with the attached Figures 1-4 A misassembly prevention mechanism for installing copper bars of a battery cluster is used to be installed between adjacent battery packs 6. Therefore, in a battery cluster, multiple misassembly prevention mechanisms of the present utility model need to be placed;

[0028] The misassembly prevention mechanism includes a partition part 1 and a baffle part 2. The partition part 1 is installed between two adjacent battery packs 6, and the baffle part 2 is located on the top surface of the partition part 1 and is correspondingly located above the battery pack 6;

[0029] Among them, the partition part 1 can make the intervals between the battery packs 6 the same, so as to ensure a certain installation position of the copper bar 7 and avoid the occurrence of misalignment of the copper bar 7 during installation; while the baffle part 2 correspondingly blocks the space between the series-connected copper bar 7 and the parallel-connected copper bar 7 of the battery pack 6, thus effectively eliminating the possibility of misconnection between the series-connected copper bar 7 and the parallel-connected copper bar 7, and further ensuring that the copper bar 7 can be in the correct installation position.

[0030] Embodiment 2 is as follows:

[0031] On the basis of Embodiment 1, the partition part 1 is further defined. The partition part 1 includes a central plate 11 and partition strips 12. A plurality of partition strips 12 are respectively fixedly arranged on both side plates of the central plate 11, and the partition strips 12 are in contact with the side surface of the corresponding battery pack 6. By setting the partition strips 12 to limit the distance between the battery packs 6, the scheme of using a thick central plate 11 can be replaced, thus having the effects of saving energy and reducing the volume of the partition part 1;

[0032] In addition, according to the different distances that the central plate 11 penetrates into the gap between the battery packs 6, the number of partition strips 12 is correspondingly adjusted, which can improve the contact and support effect of the partition part 1 on two adjacent battery packs 6, that is, when the height of the battery pack 6 is higher, the distance that the central plate 11 penetrates into the gap is longer, and the number of corresponding partition strips 12 is also more, which can provide stable contact and support for the battery pack 6.

[0033] Specifically, another embodiment of the partition portion 1 is that, on the basis of Embodiment 2, it is defined that two partition strips 12 are provided on both side plates of the central plate 11. In this embodiment, the number of the partition strips 12 is defined. Thus, in Embodiment 2, when the distance that the central plate 11 penetrates into the gap between the battery packs 6 is different, instead of adjusting the number of the partition strips 12, the distance between the partition strips 12 is changed, and the battery packs 6 can still be provided with stable abutting support under different battery pack 6 specifications. Compared with the abutting support method of Embodiment 2, the number of the partition strips 12 can be further reduced in this embodiment, so as to achieve the effect of saving resources.

[0034] In addition, a limit cover 3 is provided between the partition portion 1 and the baffle portion 2. The limit cover 3 is located on the top surface of the battery pack 6. After the partition portion 1 is placed into the gap between two adjacent battery packs 6, the limit cover 3 can limit the penetration distance of the partition portion 1, so as to ensure that the baffle portion 2 will not penetrate therewith. In addition, the limit cover 3 is set to be arc-shaped, and the arc arch end of the limit cover 3 faces the baffle portion 2, which can reduce the contact area between the limit cover 3 and the top surface of the battery pack 6, and thus avoid the possibility of the limit cover 3 scratching the battery pack 6.

[0035] Embodiment 3 is as follows:

[0036] On the basis of Embodiment 1, the partition portion 1 and the baffle portion 2 are further defined, that is, both the partition portion 1 and the baffle portion 2 are set as multi-section structures, and a docking component is provided between adjacent partition portions 1. By setting the partition portion 1 and the baffle portion 2 as multi-section structures, the length of the anti-misassembly mechanism can be flexibly adjusted as needed, so as to adapt to different specifications of the battery packs 6, and avoid affecting the installation between the battery packs 6 due to the too long length of the anti-misassembly mechanism. The docking component enables two sections of the baffle portion 2 to be connected as a whole, ensuring the integrity of the assembled multi-section baffle portion 2 and partition portion 1.

[0037] It should be noted that both the partition portion 1 and the baffle portion 2 are set as multi-section structures, which means that the whole anti-misassembly mechanism is composed of multiple parts docked, so that the overall length of the anti-misassembly mechanism can be changed by adjusting the number of sections.

[0038] In addition, the docking component includes a permanent magnet 4 and a magnetic attraction block 5. The permanent magnet 4 is located on both side surfaces of a certain section of the partition portion 1, and the magnetic attraction block 5 is located on both side surfaces of another section of the partition portion 1. The structure of magnet adsorption makes the disassembly and assembly between two sections of the partition portion 1 more convenient, and thus makes the overall combination process of the anti-misassembly mechanism more convenient.

[0039] When implementing the anti-misassembly mechanism for installing copper bars of a battery cluster described in the present utility model, first place the partition portion 1 on one side of the first battery pack among two adjacent battery packs 6, and then install the second battery pack. At this time, the second battery pack and the first battery pack will clamp the partition portion 1, and the baffle portion 2 is correspondingly located above the two battery packs 6, separating the installation position of the series copper bar of the first battery pack from the installation position of the parallel copper bar of the second battery pack. Finally, install the copper bars at the corresponding positions of the first battery pack and the second battery pack;

[0040] It can effectively prevent one end of the series copper bar from being installed at the installation position of the series copper bar of the first battery pack, while the other end of the series copper bar is installed at the installation position of the parallel copper bar of the second battery pack, resulting in misassembly of the copper bar;

[0041] It should be noted that according to the different widths of the battery packs 6, the number of sections used in this anti-misassembly mechanism is also different.

[0042] The parts not detailed in the present utility model are the prior art. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model; therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model, and any reference signs in the claims should not be regarded as limiting the claims involved.
