[0021]In this embodiment, since the first limiting groove and the second limiting groove are separated from each other along the first direction and misaligned in the second direction, with the partition located between the first and second limiting grooves, the first and second limiting grooves are essentially not connected and are separated by the partition.

Each battery pack contains multiple cells, which are combined and welded together to enable higher power output. However, connecting the individual cells requires welding adjacent terminals and then installing busbars, including positive and negative busbars. When connecting other components, these busbars may come into contact, potentially causing short circuits and compromising the battery pack's safety. Utility Model Content

[0004] In a first aspect, embodiments of this application provide an insulating support for a battery module. The insulating support includes a first limiting groove, a second limiting groove, and a partition plate disposed thereon. The first limiting groove and the second limiting groove are separated from each other along a first direction, and the partition plate is located between the first limiting groove and the second limiting groove.

[0012] Both the first and second latching members are connected to the substrate, and the first and second latching members are spaced apart along the first direction. A portion of the substrate is located between the first and second latching members. The gap between the first and second latching members communicates with the first limiting groove. The first latching member, the second latching member, and the first limiting groove together limit the first conductive busbar.
[0013] Optionally, the first snap-fit component includes a first snap-fit plate and a first snap-fit hook, wherein the first snap-fit plate is connected to the substrate and the first snap-fit hook is connected to the surface of the first snap-fit plate facing the second snap-fit plate;

[0016] Optionally, the partition has a notch, and the notch is opposite to the second snap-fit member in the first direction, the notch abutting the second snap-fit member so that the second snap-fit member is deformable along the first direction.
[0017] Optionally, the substrate has a weight-reducing groove, which is opposite to the second limiting groove in a third-direction upward position.
[0018] In a second aspect, embodiments of this application provide a battery pack, the battery pack including a battery module, a first conductive busbar, a second conductive busbar, and an insulating support for the battery module as described in any one of the first aspects above;

[0021] In this embodiment, since the first limiting groove and the second limiting groove are separated from each other along the first direction and misaligned in the second direction, with the partition located between the first and second limiting grooves, the first and second limiting grooves are essentially not connected and are separated by the partition. Therefore, when the insulating support is applied to the battery pack, once the first conductive busbar of the battery module is accommodated in the first limiting groove and the second conductive busbar of the battery module is accommodated in the second limiting groove, the first and second conductive busbars are separated by the partition, effectively preventing contact between the first and second conductive busbars and thus avoiding a potential short circuit in the battery pack. In other words, in this embodiment, by providing the first and second limiting grooves on the insulating support, and by separating the first and second limiting grooves from each other, the first and second conductive busbars of the battery module are effectively separated by the partition when the insulating support is applied to the battery pack, preventing contact between the first and second conductive busbars and thus avoiding a potential short circuit in the battery pack, thereby effectively improving the safety of the battery pack.

Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0032] 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", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship 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.
[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0034] like Figure 1As shown, the insulating bracket is provided with a first limiting groove 001, a second limiting groove 002, and a partition 13. The first limiting groove 001 and the second limiting groove 002 are separated from each other along the first direction X, and the partition 13 is located between the first limiting groove 001 and the second limiting groove 002. The first limiting groove 001 and the second limiting groove 002 are misaligned in the second direction Y. The first limiting groove 001 is used to accommodate the first conductive bar 100 of the battery module 300, the second limiting groove 002 is used to accommodate the second conductive bar 200 of the battery module 300, and the partition 13 separates the first conductive bar 100 and the second conductive bar 200.
[0035] In this embodiment, since the first limiting groove 001 and the second limiting groove 002 are separated from each other along the first direction X, and the first limiting groove 001 and the second limiting groove 002 are misaligned in the second direction Y, and the partition 13 is located between the first limiting groove 001 and the second limiting groove 002, the first limiting groove 001 and the second limiting groove 002 are essentially not connected and are separated by the partition 13. Thus, when the insulating bracket is applied in the battery pack, once the first conductive busbar 100 of the battery module 300 is accommodated in the first limiting groove 001 and the second conductive busbar 200 of the battery module 300 is accommodated in the second limiting groove 002, the first conductive busbar 100 and the second conductive busbar 200 will be separated by the partition 13, thereby effectively preventing the first conductive busbar 100 and the second conductive busbar 200 from contacting each other, which could lead to a short circuit in the battery pack. That is, in this embodiment of the application, by setting a first limiting groove 001, a second limiting groove 002 and a partition 13 on the insulating bracket, and separating the first limiting groove 001 and the second limiting groove 002 from each other, the insulating bracket is applied to the battery pack, and the first conductive bar 100 and the second conductive bar 200 of the battery module 300 are effectively separated by the partition 13, avoiding contact between the first conductive bar 100 and the second conductive bar 200, which could lead to a short circuit in the battery pack, thereby effectively improving the safety of the battery pack.
[0036] It should be noted that, in the embodiments of this application, the first conductive bus 100 can be the positive bus of the battery module 300, and the second conductive bus 200 can be the negative bus of the battery module 300. Of course, the first conductive bus 100 can also be the negative bus of the battery module 300, and the second conductive bus 200 can also be the positive bus of the battery module 300. This embodiment of the application does not limit the specific application in this regard.
[0037] In addition, in this embodiment, the insulating bracket is formed by processing an insulating material, which can be plastic. Of course, the insulating material can also be other materials with insulating properties, such as resin.
[0038] Furthermore, in this embodiment, the first direction X intersects with the second direction Y. Specifically, the first direction X and the second direction Y can be perpendicular. Of course, the angle between the intersection of the first direction X and the second direction Y can be close to 90°. For example, the angle between the intersection of the first direction X and the second direction Y is 85°, or even 95°.
[0039] In some embodiments, such as Figure 2 As shown, the insulating support includes a substrate 11 and a first baffle 12; the first baffle 12 and the partition 13 are connected to the same surface of the substrate 11, and the first baffle 12, the partition 13 and the substrate 11 form a first limiting groove 001, and the second limiting groove 002 is located on the side of the partition 13 away from the first baffle 12.
[0040] Since the first baffle 12 and the partition 13 are connected to the same surface of the substrate 11, the first baffle 12, the partition 13 and the substrate 11 can be arranged to form a first limiting groove 001. That is, the surfaces of the first baffle 12, the partition and the substrate 11 are arranged to form a first limiting groove 001, so the first conductive bus 100 can be directly installed in the first limiting groove 001. Thus, the first baffle 12 and the partition 13 can limit the first conductive bus 100, ensuring that the position of the first conductive bus 100 in the first limiting groove 001 is relatively fixed, and avoiding the problem of the first conductive bus 100 easily shaking in the first limiting groove 001.
[0041] It should be noted that the first baffle 12, the partition plate and the substrate 11 can be integrally formed, that is, the insulating support can be directly formed by integral molding process, which makes the structure of the insulating support high in strength and the various components of the insulating support not easy to separate.
[0042] In some embodiments, such as Figure 2 As shown, the insulating support also includes a second baffle 20, which is connected to the substrate 11, and there is a gap between the second baffle 20 and the substrate 11 along the third direction Z, the gap forming a second limiting groove 002.
[0043] Since the second baffle 20 is connected to the substrate 11, and there is a gap between the second baffle 20 and the substrate 11 along the third direction Z, this gap can form a second limiting groove 002. Therefore, when the second conductive bus 200 is installed in the second limiting groove 002, the second conductive bus 200 can pass through the second limiting groove 002, and the substrate 11 and the second baffle 20 can limit the second conductive bus 200, preventing the second conductive bus 200 from easily shaking. In other words, by setting the second baffle 20, not only is it convenient to form the second limiting groove 002, but it is also convenient to limit the second conductive bus 200.
[0044] It should be noted that, in this embodiment, the second baffle 20 and the substrate 11 can be integrally formed, that is, the substrate 11 and the second baffle 20 can be directly formed by integral molding process, which makes the structure of the insulating support high in strength and the various components in the insulating support not easy to separate. Of course, the second baffle 20 and the substrate 11 can also be connected by connection process, for example, by welding process.
[0045] In some embodiments, such as Figure 2 As shown, the second baffle 20 has a limiting protrusion 21 on its surface facing the substrate 11, and the limiting protrusion 21 is located at the end of the second baffle 20 away from the partition 13 in the first direction X, and the limiting protrusion 21 extends in the direction toward the substrate 11.
[0046] With this configuration, once the second conductive bus 200 is installed in the second limiting groove 002, the limiting protrusion 21 can limit the second conductive bus 200, preventing it from easily detaching from the second limiting groove 002. That is, when the second conductive bus 200 is installed in the second limiting groove 002, the substrate 11, the second baffle 20, and the limiting protrusion 21 together limit the second conductive bus 200, effectively ensuring its stability within the second limiting groove 002.
[0047] In some embodiments, such as Figure 3 As shown, the partition 13 has a first cutout 131. With this design, the first cutout 131 can effectively reduce the weight of the partition 13, thereby reducing the weight of the insulating bracket and preventing a significant increase in the weight of the battery pack after the insulating bracket is installed in the battery pack.
[0048] It should be noted that a groove can be formed on the partition 13, which forms the first hollow part 131.
[0049] Additionally, in the embodiments of this application, such as Figure 4 As shown, the partition 13 may include a baffle plate 132, a sealing plate 133, and a fixing plate 134; the baffle plate 132 is an arc-shaped plate, and in the third direction Z, the sealing plate 133 is connected to one side of the baffle plate 132, and the fixing plate 134 is connected to the side of the fixing plate 134 away from the baffle plate 132; wherein, along the first direction X, the baffle plate 132 has at least two opposing sub-plates, and there is a gap between the two sub-plates, which forms a first hollow portion 131, thereby reducing the weight of the partition 13.
[0050] In addition, the blocking plate 133 is connected to one side of the partition plate 132, and the fixing plate 134 is connected to the side of the fixing plate 134 away from the partition plate 132. Thus, after the fixing plate 134 is connected to the mounting base plate 11, it can be ensured that the partition plate 132 is connected to the mounting base plate 11, so that the partition plate 13 is more firmly fixed to the mounting base plate 11.
[0051] It should be noted that the partition plate 132 may include a first sub-plate 1321, a connecting plate 1322, and a second sub-plate 1323. The connecting plate 1322 is connected to the first sub-plate 1321 and the second sub-plate 1323 respectively. The connecting plate 1322 is an arc-shaped plate. The sealing plate 133 is connected to the first sub-plate 1321, the connecting plate 1322, and the second sub-plate 1323 respectively in the third direction Z. The fixing plate 134 is connected to the sealing plate 133. The first sub-plate 1321 and the second sub-plate 1323 are distributed at intervals along the first direction X, and the connecting plate 1322 is connected to the first sub-plate 1321 and the second sub-plate 1323 respectively.
[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, the insulating bracket also includes a first snap-fit member 30 and a second snap-fit member 40; both the first snap-fit member 30 and the second snap-fit member 40 are connected to the substrate 11, and the first snap-fit member 30 and the second snap-fit member 40 are distributed at intervals along the first direction X, with a portion of the substrate 11 located between the first snap-fit member 30 and the second snap-fit member 40, and the gap between the first snap-fit member 30 and the second snap-fit member 40 communicates with the first limiting groove 001, and the first snap-fit member 30, the second snap-fit member 40 and the first limiting groove 001 together limit the first conductive bus 100.
[0053] Since the first latching member 30 and the second latching member 40 are spaced apart along the first direction X, and a portion of the substrate 11 is located between the first latching member 30 and the second latching member 40, when the first conductive bus 100 is installed in the first limiting groove 001, a portion of the first conductive bus 100 can pass through the gap between the first latching member 30 and the second latching member 40, and both the first latching member 30 and the second latching member 40 are in contact with the first conductive bus 100, thereby limiting the first conductive bus 100 by the first latching member 30 and the second latching member 40, ensuring that the first conductive bus 100 is not easily shaken. In addition, once the first conductive bus 100 is installed into the first limiting groove 001, the portion of the substrate 11 located between the first latching member 30 and the second latching member 40 will also contact the first conductive bus 100. This means that the substrate 11, the first latching member 30, and the second latching member 40 will all limit the first conductive bus 100. That is, the first latching member 30, the second latching member 40, and the first limiting groove 001 together limit the first conductive bus 100, effectively preventing the problem of the first conductive bus 100 being prone to shaking. In addition, the first snap-fit member 30 is equivalent to being independent of the second baffle 20, and the second snap-fit member 40 is equivalent to being an independent partition 13. Thus, the first snap-fit member 30 and the second snap-fit member 40 can have a certain degree of deformation. When installing the first conductive bus 100, if the gap between the first snap-fit member 30 and the second snap-fit member 40 is slightly smaller than the size of the first conductive bus 100, the first conductive bus 100 can apply force to the first snap-fit member 30 and the second snap-fit member 40, causing the first snap-fit member 30 and the second snap-fit member 40 to deform, ensuring that the first conductive bus 100 can be installed between the first snap-fit member 30 and the second snap-fit member 40.
[0054] It should be noted that when the insulating support includes a substrate 11, a second baffle 20, and a partition 13, both the first latching member 30 and the second latching member 40 are connected to the substrate 11. The first latching member 30 is located on one side of the second baffle 20 in the second direction Y, and the second latching member 40 is located on one side of the partition 13 in the second direction Y. The first latching member 30 and the second latching member 40 are opposite each other in the first direction X. The first latching member 30 is essentially independent of the substrate 11 and the second baffle 20, allowing it to have a certain deformation under stress. Similarly, the second latching member 40 is also essentially independent of the substrate 11 and the partition 13, allowing it to have a certain deformation under stress.
[0055] In some embodiments, such as Figure 3As shown, the first snap-fit member 30 includes a first snap-fit plate 31 and a first snap-fit hook 32. The first snap-fit plate 31 is connected to the substrate 11, and the first snap-fit hook 32 is connected to the surface of the first snap-fit plate 31 facing the second snap-fit plate 41. The second snap-fit member 40 includes a second snap-fit plate 41 and a second snap-fit hook 42. The second snap-fit plate 41 is connected to the substrate 11, and the second snap-fit hook 42 is connected to the surface of the second snap-fit plate 41 facing the first snap-fit plate 31. The first snap-fit hook 32 and the second snap-fit hook 42 snap-fit the first conductive bus 100.
[0056] Since the first hook 32 is connected to the surface of the first latching plate 31 facing the second latching plate 41, and the second hook 42 is connected to the surface of the second latching plate 41 facing the first latching plate 31, the first hook 32 and the second hook 42 are positioned opposite each other. Therefore, when the first conductive busbar 100 is installed in the first limiting groove 001, the first hook 32 and the second hook 42 can support the first conductive busbar 100. That is, the first hook 32 and the second hook 42 can engage the first conductive busbar 100, and the first latching plate 31 and the second latching plate 41 can contact the first conductive busbar 100, thereby ensuring that the first conductive busbar 100 is effectively fixed and thus ensuring that the first conductive busbar 100 is not easily detached from the first limiting groove 001.
[0057] It should be noted that the first snap-fit plate 31, the second snap-fit plate 41, and the substrate 11 can be integrally formed, that is, the first snap-fit plate 31, the second snap-fit plate 41, and the substrate 11 are directly formed by integral molding process, which improves the strength of the insulating bracket and makes the components in the insulating bracket less prone to separation. Specifically, when the insulating bracket includes the substrate 11, both the first snap-fit plate 31 and the second snap-fit plate 41 are connected to the substrate 11, and the first snap-fit plate 31, the second snap-fit plate 41, and the substrate 11 can be integrally formed.
[0058] In some embodiments, such as Figure 3 As shown, the partition 13 has a notch 1301, and the notch 1301 is opposite to the second snap-fit member 40 in the first direction X. The notch 1301 avoids the second snap-fit member 40, so that the second snap-fit member 40 can be deformed along the first direction X. With this arrangement, when installing the first conductive bus 100, even if the size of the first conductive bus 100 is large enough to deform the second snap-fit member 40, the presence of the notch 1301 ensures that the second snap-fit member 40 can deform along the first direction X. That is, the notch 1301 avoids the second snap-fit member 40, allowing the snap-fit member 40 to be deformable, thereby facilitating the installation of the first conductive bus 100.
[0059] In some embodiments, such as Figure 4As shown, the substrate 11 has a weight-reducing groove 101, which is positioned opposite to the second limiting groove 002 in the third direction Z. This arrangement effectively reduces the weight of the substrate 11, thereby reducing the weight of the insulating support and preventing a significant increase in the weight of the battery pack after the insulating support is installed in the battery pack.
[0060] It should be noted that two weight-reduction grooves 101 can be provided on the substrate 11. One weight-reduction groove 101 corresponds to the first limiting groove 001, and the other weight-reduction groove 101 corresponds to the second limiting groove 002, which can further reduce the weight of the substrate 11. The thickness of the substrate 11 at the weight-reduction groove 101 corresponding to the second limiting groove 002 is greater than the thickness at the weight-reduction groove 101 corresponding to the first limiting groove 001, which allows the second limiting groove 002 to have a larger width. When the second conductive bus 200 passes through the second limiting groove 002, the second limiting groove 002 provides better restraint for the second conductive bus 200.
[0061] Additionally, in some embodiments, such as Figure 1 and Figure 2 As shown, a connecting plate 111 is connected to the substrate 11, and the connecting plate 111 is provided with a reinforcing structure 50. The reinforcing structure 50 and the first baffle 12 are located on the same side of the substrate 11. The reinforcing structure 50 includes a plurality of reinforcing plates 51, and at least two of the plurality of reinforcing plates 51 intersect.
[0062] Since the reinforcing structure 50 and the first baffle 12 are located on the same side of the substrate 11, the reinforcing structure 50 has less impact on the substrate 11 when the insulating support is installed in the battery pack. This allows the substrate 11 to be as close as possible to the first conductive busbar 100 and the second conductive busbar 200, facilitating the installation of the first conductive busbar 100 in the first limiting groove 001 and the second conductive busbar 200 in the second limiting groove 002. Furthermore, at least two of the reinforcing plates 51 intersect, resulting in higher strength at the intersection, further enhancing the strength of the insulating support. In other words, by providing the reinforcing structure 50, the strength of the insulating support can be effectively improved.
[0063] It should be noted that, in this embodiment, the number of reinforcing plates 51 can be set according to actual needs. For example, there may be three reinforcing plates 51, with two extending along the second direction Y and spaced apart along the first direction X, and the other reinforcing plate 51 intersecting with the other two. Alternatively, there may be four reinforcing plates 51, with two extending along the second direction Y and spaced apart along the first direction X, and the other two extending along the first direction X and spaced apart along the second direction Y. The specific number of reinforcing plates 51 is not limited in this embodiment.
[0064] Furthermore, in this embodiment, when the substrate 11 has two weight-reducing grooves 101, the partition 13 has a first hollow portion 131, and the reinforcing structure 50 includes multiple reinforcing plates 51, the thickness of the substrate 11 of the insulating bracket, the thickness of the substrate 11 at the second hollow portion 101, the thickness of the partition 13 at the second hollow portion 101, and the thickness of the reinforcing plates 51 are all equal, which facilitates the design of molds for the production of the insulating bracket. That is, in this embodiment, the thickness of the plates is equal.
[0065] Additionally, in some embodiments, such as Figure 2 and Figure 3 As shown, at least one slot 111 is provided on each side of the first latch 30 and the second latch 40 in the second direction Y, and the at least one slot 111 is distributed along the first direction X. With this arrangement, the presence of the slot 111 can effectively reduce the weight of the substrate 11, thereby reducing the weight of the insulating support, so that after the insulating support is installed in the battery pack, the weight of the battery pack is not increased significantly.
[0066] It should be noted that the number of slots 111 on either side of the second direction Y of the substrate 11 can be set according to actual needs. For example, the number of slots 111 on either side of the second direction Y of the substrate 11 may be 2, or the number of slots 111 on either side of the second direction Y of the substrate 11 may be 3. In this respect, the embodiments of this application do not limit the scope.
[0067] In this embodiment, since the first limiting groove 001 and the second limiting groove 002 are separated from each other along the first direction X, and the first limiting groove 001 and the second limiting groove 002 are misaligned in the second direction Y, and the partition 13 is located between the first limiting groove 001 and the second limiting groove 002, the first limiting groove 001 and the second limiting groove 002 are essentially not connected and are separated by the partition 13. Thus, when the insulating bracket is applied in the battery pack, once the first conductive busbar 100 of the battery module 300 is accommodated in the first limiting groove 001 and the second conductive busbar 200 of the battery module 300 is accommodated in the second limiting groove 002, the first conductive busbar 100 and the second conductive busbar 200 will be separated by the partition 13, thereby effectively preventing the first conductive busbar 100 and the second conductive busbar 200 from contacting each other, which could lead to a short circuit in the battery pack. In other words, in this embodiment, by providing a first limiting groove 001, a second limiting groove 002, and a partition 13 on the insulating bracket, with the first limiting groove 001 and the second limiting groove 002 being separated from each other, the insulating bracket is applied to the battery pack. The first conductive bar 100 and the second conductive bar 200 of the battery module 300 are effectively separated by the partition 13, preventing contact between the first conductive bar 100 and the second conductive bar 200, which could lead to a short circuit in the battery pack, thus effectively improving the safety of the battery pack. Furthermore, the presence of the weight-reducing groove 101 reduces the weight of the insulating bracket, which helps to reduce the weight of the battery module 300 after the insulating bracket is installed, facilitating the widespread adoption of the battery module 300.
[0068] This application provides a battery pack, such as... Figure 5 , Figure 6 and Figure 7 As shown, the battery pack includes a battery module 300, a first conductive busbar 100, a second conductive busbar 200, and an insulating bracket as described in any of the above embodiments.
[0069] Both the first conductive bus 100 and the second conductive bus 200 are connected to the battery module 300. The first conductive bus 100 is disposed in the first limiting groove 001, and the second conductive bus 200 is disposed in the second limiting groove 002.
[0070] It should be noted that the first conductive bus 100 can be formed of metal, for example, the first conductive bus 100 is an aluminum bus, or for another example, the first conductive bus 100 is a copper bus; similarly, the second conductive bus 200 can be formed of metal, for example, the second conductive bus 200 is an aluminum bus, or for another example, the second conductive bus 200 is a copper bus.
