[0026] In one embodiment, as shown in Figures 1 to 7, a bracket assembly is provided, which is applied to a battery rack 10, and the battery rack 10 includes a battery rack body 100, and the battery rack body 100 is provided with a multi-layer battery storage area 110; the bracket assembly includes a plurality of first brackets 20; the first brackets 20 are used to support the battery pack 50; the plurality of first brackets 20 are distributed in the multi-layer battery storage area 110, and the plurality of first brackets 20 in the same battery storage area 110 are arranged in multiple columns and multiple rows; two adjacent first brackets 20 in the same row are staggered so that two adjacent battery packs 50 in the same row are staggered.

[0027] Among them, the battery rack 10 can be used to store and support the fixed battery pack 50. The battery rack 10 includes a battery rack body 100. The battery rack body 100 can be divided into multiple layers. For example, the battery rack body 100 can be provided with a multi-layer battery storage area 110. The battery rack body 100 can also be provided with a high-voltage box layer. The high-voltage box layer can be located on the top of the battery rack body 100. The battery storage area 110 can be used to store multiple battery packs 50. The battery pack 50 can be composed of multiple battery modules connected in series. The battery module can be a battery module of a single-row battery cell group, a battery module of a double-row battery cell group, or a battery module of a multi-row battery cell group. The battery cell group can be composed of multiple battery cells connected in series and / or in parallel. Exemplarily, the battery cell can be a lithium battery cell.

[0028] The support assembly may include multiple first brackets 20, with each battery storage area 110 being provided with multiple first brackets 20. For example, each battery storage area 110 is provided with the same number of first brackets 20, and the first brackets 20 may be installed in the corresponding battery storage area 110 by welding or screwing.

[0029] The first bracket 20 can be used to support the battery pack 50. For example, the first bracket 20 has a long strip structure. The multiple first brackets 20 in the same battery storage area 110 are arranged in multiple columns and rows, the two adjacent first brackets 20 in the same row are staggered, and the two adjacent first brackets 20 in the same column are spaced apart. When multiple battery packs 50 are set on the corresponding first brackets 20, the multiple battery packs 50 in the same battery storage area 110 are arranged in multiple columns and rows, and the two adjacent battery packs 50 in the same row are staggered.

[0030] Exemplarily, the battery pack 50 is a convex battery pack 50, with a rectangular bottom and a rectangular top. The bottom area of ​​the battery pack 50 is larger than the top area. The bottom side of the battery pack 50 is positioned on the first bracket 20. By staggering two adjacent first brackets 20 in the same row, the bottom side of the two adjacent battery packs 50 in the same row are staggered. In one example, multiple first brackets 20 in the same column of the same battery storage area 110 are parallel to each other, and multiple first brackets 20 in the same row of the same battery storage area 110 are parallel to each other.

[0031] The first bracket 20 includes a first end and a second end, the first end of the first bracket 20 is opposite to the second end, the battery pack 50 includes a front end and a rear end, the front end of the battery pack 50 is opposite to the rear end. Exemplarily, during the installation of the battery pack 50, the battery pack 50 is placed on the first bracket 20, and the user applies a thrust to the front end of the battery pack 50, so that the rear end of the battery pack 50 is pushed toward the first end along the second end of the first bracket 20 until the rear end of the battery pack 50 abuts against the first end of the first bracket 20, thereby achieving the installation and fixation of the battery pack 50.

[0032] In this embodiment, the bracket assembly is applied to the battery rack 10, and the battery rack 10 includes a battery rack body 100, and the battery rack body 100 is provided with a multi-layer battery storage area 110; the bracket assembly includes multiple first brackets 20; the first brackets 20 are used to support the battery pack 50; the multiple first brackets 20 are distributed in the multi-layer battery storage area 110, and the multiple first brackets 20 in the same battery storage area 110 are arranged in multiple columns and multiple rows; the two adjacent first brackets 20 in the same row are staggered, so that the two adjacent battery packs 50 in the same row are staggered, and there is no need to modify the structure of the battery pack 50, which is more conducive to adapting to standard containers. The embodiment of the present application ensures that a battery pack 50 can be placed on each first bracket 20 by staggering two adjacent first brackets 20 in the same row and coordinating the battery pack 50 with the first bracket 20. Moreover, by staggering the first bracket 20, one battery pack 50 of the two adjacent battery packs 50 in the same row is staggered with the other battery pack 50, thereby reducing the installation width of the battery pack 50 and allowing a longer battery pack 50 to fit into a standard container, thereby improving the versatility of the standard container.

[0033] In one embodiment, as shown in Figures 8 and 9, the battery pack 50 includes a battery pack body 510 and a support plate 520. The battery pack body 510 is disposed on the support plate 520, and the support plate 520 is provided with a first protrusion 522 protruding from the battery pack body 510; the first protrusions 522 of two adjacent battery packs 50 in the same row are staggered.

[0034] The battery pack 50 can be divided into a battery pack body 510 and a support plate 520. The battery pack body 510 is mounted on the support plate 520. The surface area of ​​the support plate 520 is larger than the bottom area of ​​the battery pack body 510. The support plate 520 and the battery pack body 510 form a convex structure of the battery pack 50. It should be noted that the support plate 520 may be provided with a liquid cooling channel to cool and dissipate heat from the battery pack 50.

[0035] The support plate 520 is provided with a first protrusion 522, which protrudes from the battery pack body 510. For example, during the installation of the battery pack 50, the support plate 520 of the battery pack 50 is placed on the first bracket 20. The user applies a pushing force to the front end of the battery pack 50, so that the rear end of the battery pack 50 is pushed along the second end toward the first end of the first bracket 20 until the first protrusion 522 of the support plate 520 abuts the first end of the first bracket 20, thereby completing the installation of the battery pack 50.

[0036] By staggering two adjacent first brackets 20 in the same row, when a battery pack 50 is mounted on the first brackets 20, the first protrusion 522 of one battery pack 50 is offset against the first protrusion 522 of the other battery pack 50 (i.e., the bottom edge of the convex battery pack 50 rests on the step of the other convex battery pack 50). This achieves staggered placement of the two battery packs 50, reduces the installation width of the battery packs 50, allows longer battery packs 50 to fit into standard containers, and improves the versatility of standard containers. It should be noted that the staggered distance between two adjacent first brackets 20 in the same row is determined by the protruding dimensions of the first protrusions 522 of the battery packs 50.

[0037] In one example, the protrusion distance of the first protrusion 522 is greater than or equal to the staggered distance between two adjacent first brackets 20 in the same row. The support plate 520 of the battery pack 50 is placed on the first bracket 20, with the first protrusion 522 of the support plate 520 abutting the first end of the first bracket 20. This allows the battery packs 50 in two adjacent first brackets 20 in the same row to be staggered, i.e., the first protrusion 522 of one battery pack 50 is offset from the first protrusion 522 of another battery pack 50. This allows two longer battery packs 50 to be placed in two adjacent first brackets 20 in the same row.

[0038] In one embodiment, as shown in Figures 8 and 9, the support plate 520 is further provided with a second protrusion 526 protruding from the battery pack body 510. The second protrusion 526 of the support plate 520 protrudes from the battery pack body 510. The second protrusion 526 is connected to the first protrusion 522. For example, the support plate 520 is a rectangular structure, with the first protrusion 522 located on a first short side of the support plate 520 and the second protrusion 526 located on a first long side of the support plate.

[0039] In one embodiment, as shown in FIG. 4 and FIG. 5 , the first bracket 20 is cross-disposed with a first panel 210 and a second panel 220 ; the first panel 210 and the second panel 220 are respectively used to support adjacent two sides of the battery pack 50 .

[0040] The first bracket 20 can be made of metal and includes a first panel 210. The first panel 210 is a long, rectangular panel that supports the second side of the battery pack 50. The first bracket 20 also includes a second panel 220 connected to the first panel 210. The second panel 220 supports the first side of the battery pack 50, with the first side and the second side of the battery pack 50 adjacent to each other. For example, the second panel 220 is connected to the first end of the first panel 210 and perpendicular to the first panel 210. In one example, the first panel 210 can include a guide groove. The second side of the battery pack 50 cooperates with the guide groove of the first panel 210, allowing the second side of the battery pack 50 to be pushed and moved along the guide groove of the first panel 210. For example, in two adjacent first brackets 20 in the same row, the second panel 220 of one first bracket 20 is parallel to the second panel 220 of the other second bracket.

[0041] By staggering two adjacent first brackets 20 in the same row, the second panel 220 of one first bracket 20 is staggered with the second panel 220 of another first bracket 20. During the installation of the battery pack 50, the second side of the battery pack 50 is placed on the first panel 210. The user applies a thrust to the front end of the battery pack 50, so that the rear end of the battery pack 50 is pushed toward the first end along the second end of the first panel 210 until the first side of the battery pack 50 abuts against the second panel 220, thereby limiting and fixing the battery pack 50, thereby achieving the installation and setting of the battery pack 50 on the first bracket 20, so that two adjacent battery packs 50 in the same row are staggered, which can enable longer battery packs 50 to fit into standard containers, thereby improving the versatility of standard containers.

[0042] Exemplarily, the first side of the battery pack 50 is the first protrusion 522 of the support plate 520, and the second side of the battery pack 50 is the second protrusion 526 of the support plate 520. During the installation of the battery pack 50, the second protrusion 526 is abutted against the first panel 210. The user applies a thrust to the front end of the battery pack 50, so that the rear end of the battery pack 50 is pushed toward the first end along the second end of the first panel 210 until the first protrusion 522 abuts against the second panel 220, thereby limiting and fixing the battery pack 50, thereby realizing the installation and setting of the battery pack 50 on the first bracket 20, so that the second protrusions 526 of two adjacent battery packs 50 in the same row are staggered, so that longer battery packs 50 can be adapted to standard containers, thereby improving the versatility of standard containers.

[0043] In one embodiment, as shown in FIG. 4 and FIG. 5 , the second panel 220 is provided with a snap-fit ​​member 222 , and the snap-fit ​​member 222 is used to snap-fit ​​the battery pack 50 .

[0044] The clip 222 may be provided on the second panel 220 by welding or screwing. In another example, the clip 222 and the second panel 220 are an integrally formed structure.

[0045] During the installation of the battery pack 50, the second side of the battery pack 50 is placed on the first panel 210, and the user applies a thrust to the front end of the battery pack 50, so that the rear end of the battery pack 50 is pushed toward the first end along the second end of the first panel 210. At the same time, the first side of the battery pack 50 is clamped to the clamping part 222 of the second panel 220, so that the rear end of the battery pack 50 is limited and fixed to the second panel 220, thereby enhancing the installation firmness and convenience of the battery pack 50 and preventing the rear end of the battery pack 50 from loosening.

[0046] For example, as shown in Figure 10, the first side of the battery pack 50 (such as the first protrusion 522) is provided with a slot 524 corresponding to the clamping member 222; the first side of the battery pack 50 is clamped to the clamping member 222 of the second panel 220 through the slot 524 to limit and fix the first protrusion 522 on the second panel 220.

[0047] In one embodiment, the clamping member 222 includes a first clamping section 2222 and a second clamping section 2224; the second end of the first clamping section 2222 is connected to the first end of the second connecting section, and the second end of the second clamping section 2224 is arranged on the second panel 220; the first end size of the first clamping section 2222 is smaller than the second end size of the first clamping section 2222.

[0048] The first engaging section 2222 and the second engaging section 2224 are integrally formed. The first engaging section 2222 may be a conical structure, while the second engaging section 2224 may be a cylindrical structure. For example, the first engaging section 2222 is a conical structure, while the second engaging section 2224 is a cylindrical structure. The first end of the first engaging section 2222 is smaller than the second end of the first engaging section 2222. The engaging slot 524 on the first side of the battery pack 50 is larger than the first end of the first engaging section 2222. Thus, the first engaging section 2222 serves as a guide for insertion, facilitating insertion of the engaging slot 524 on the first side of the battery pack 50 into the engaging member 222 of the second panel 220.

[0049] During the installation of the battery pack 50, the second side of the battery pack 50 is placed on the first panel 210, and the user applies a thrust to the front end of the battery pack 50, so that the rear end of the battery pack 50 is pushed toward the first end along the second end of the first panel 210, and at the same time, the first side of the battery pack 50 is aligned with the first clamping section 2222 of the second panel 220, so that the clamping groove 524 of the first side of the battery pack 50 is inserted into the clamping piece 222 of the second panel 220, thereby limiting and fixing the first side of the battery pack 50 to the second panel 220, that is, limiting and fixing the rear end of the battery pack 50 to the second panel 220 of the first bracket 20, thereby enhancing the installation firmness and convenience of the battery pack 50.

[0050] In one embodiment, as shown in Figures 4 and 10, the first bracket 20 is further provided with a third panel 230 and a fourth panel 240; the third panel 230, the fourth panel 240 and the first panel 210 are enclosed to form a limiting groove, which is used to guide the battery pack 50 to be pushed toward the second panel 220 so that the battery pack 50 is clamped on the clamping part 222 of the second panel 220.

[0051] The third panel 230 is a long strip panel, the fourth panel 240 is a long strip panel, the third panel 230 and the first panel 210 are integrally formed, and the fourth panel 240 and the first panel 210 are integrally formed. Exemplarily, the third panel 230 is perpendicular to the first panel 210, the fourth panel 240 is perpendicular to the first panel 210, and the third panel 230 is parallel to the fourth panel 240.

[0052] The third panel 230 , the fourth panel 240 and the first panel 210 enclose a limiting groove, and the second side of the battery pack 50 is disposed in the limiting groove, so that the second side of the battery pack 50 is limited by the limiting groove.

[0053] During the installation of the battery pack 50, the second side of the battery pack 50 is placed in the limiting groove, and the user applies a thrust to the front end of the battery pack 50. The second side of the battery pack 50 is pushed along the limiting groove from the second end to the first end of the first panel 210, so that the card slot 524 on the first side of the battery pack 50 is aligned with the card connector 222 of the second panel 220, and then the card slot 524 on the first side of the battery pack 50 is carded to the card connector 222 of the second panel 220, so that the first side of the battery pack 50 is limited and fixed on the second panel 220, that is, the rear end of the battery pack 50 is limited and fixed on the second panel 220 of the first bracket 20, thereby enhancing the installation firmness and convenience of the battery pack 50.

[0054] In one embodiment, as shown in Figure 10, the bracket assembly further includes a buffer member 30, which is disposed on the inner wall of the third panel 230, and the buffer member 30 is located between the third panel 230 and the battery pack 50; and / or, the buffer member 30 is disposed on the inner wall of the fourth panel 240, and the buffer member 30 is located between the fourth panel 240 and the battery pack 50.

[0055] The buffer component 30 may be, but is not limited to, a foam sheet.

[0056] For example, the buffer 30 can be set on the inner wall of the third panel 230 or the inner wall of the fourth panel 240 by bonding, and then after the second side of the battery pack 50 is placed in the limiting groove, the buffer 30 can cushion the second side of the battery pack 50 to prevent the user from applying a push to the front end of the battery pack 50. When the second side of the battery pack 50 is pushed from the second end to the first end of the first panel 210 along the limiting groove, the third panel 230 or the fourth panel 240 directly squeezes or bumps the second side of the battery pack 50. In another example, the inner wall of the third panel 230 and the inner wall of the fourth panel 240 are respectively provided with the buffer 30, and then when the user applies a push to the front end of the battery pack 50 and the second side of the battery pack 50 is pushed from the second end to the first end of the first panel 210 along the limiting groove, the buffer 30 of the third panel 230 and the buffer 30 of the fourth panel 240 can simultaneously play a buffering and protective role on the second side of the battery pack 50.

[0057] In one embodiment, as shown in FIG. 5 , the first bracket 20 is further provided with a plurality of connection portions 250 for connecting to the battery rack body 100 , and the plurality of connection portions 250 protrude from the first panel 210 .

[0058] The connecting portion 250 is integrally formed with the first panel 210. For example, the first bracket 20 is provided with two connecting portions 250, one connecting portion 250 is provided adjacent to the first end of the first bracket 20, and the other connecting portion 250 is provided adjacent to the second end of the first bracket 20.

[0059] For example, the connecting portion 250 is protruding from the first panel 210, and the connecting portion 250 is provided with at least one first mounting hole, and the battery holder body 100 is provided with a second mounting hole corresponding to the first mounting hole. Then, a screw can be passed through the first mounting hole of the connecting portion 250 and the second mounting hole of the battery holder body 100, and the connecting portion 250 can be locked on the battery holder body 100, thereby achieving the installation and locking of the first bracket 20 on the battery holder body 100, while avoiding interference with the battery pack 50 installed on the first bracket 20.

[0060] In one example, as shown in FIG3 , at least one connection portion 250 is disposed adjacent to the second panel 220 ; the first panel 210 , the second panel 220 and the connection portion 250 adjacent to the second panel 220 enclose a relief portion 260 ; the relief portion 260 is used to avoid adjacent first brackets 20 in the same row.

[0061] The avoidance portion 260 is a notch-shaped structure. By arranging the connecting portion 250 adjacent to the second panel 220 and maintaining a certain distance between the connecting portion 250 and the end of the first panel 210, a notch-shaped structure is formed between the first panel 210, the second panel 220, and the connecting portion 250 adjacent to the second panel 220. That is, the first panel 210, the second panel 220, and the connecting portion 250 adjacent to the second panel 220 enclose the avoidance portion 260. As a result, the avoidance portion 260 of the first bracket 20 can avoid another first bracket 20 adjacent to the same row, thereby achieving a staggered arrangement of two first brackets 20 adjacent to the same row, thereby improving the compactness of the structure and avoiding interference with another first bracket 20 adjacent to the same row. By coordinating the battery pack 50 and the first bracket 20, it is ensured that a battery pack 50 can be placed on each first bracket 20, and by staggering the first bracket 20, one battery pack 50 in two adjacent battery packs 50 in the same row is staggered with the other battery pack 50, thereby reducing the installation width of the battery pack 50, allowing longer battery packs 50 to fit into standard containers, thereby improving the versatility of standard containers.

[0062] In one embodiment, as shown in FIG. 1 and FIG. 2 , the bracket assembly further includes a support block 40 ; a first end portion of the support block 40 is disposed on the battery rack body 100 , and a second end portion of the support block 40 is disposed on the first bracket 20 .

[0063] Among them, the support block 40 can be a support block 40 made of metal material, the first end of the support block 40 can be set on the battery rack body 100 by welding or screwing, and the second end of the support block 40 can be set on the first bracket 20 by welding or screwing.

[0064] Illustratively, the support block 40 can be divided into a first support section and a second support section. The first and second support sections are integrally formed, with the first end of the support block 40 located in the first support section and the second end of the support block 40 located in the second support section. Illustratively, the first support section is perpendicular to the second support section, and the connection between the first and second support sections forms an arc transition, thereby strengthening the support block 40, enhancing the fixation of the first bracket 20, and preventing the first bracket 20 from twisting.
