[0038] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0039] The following combination Figures 1 to 12 , describing the embodiments of the present utility model.

[0040] According to an embodiment of the present invention, on the one hand, a battery rack is provided, comprising:

[0041] Mounting rack;

[0042] Multiple support beam groups are fixed on the mounting frame at intervals along the height direction of the mounting frame, each support beam group includes two support beams 1 located at the same height, and a battery pack mounting position 5 is formed between the two support beams 1 in the support beam group;

[0043] There are multiple reinforcement members 2, and at least one reinforcement member 2 is correspondingly arranged under each support beam. Each reinforcement member 2 includes a connecting portion and a supporting portion that are fixedly connected. The connecting portion is fixed on the mounting frame, and the supporting portion is connected to the bottom of the support beam 1 for reinforcing the support beam 1. An avoidance space 3 is formed between the connecting portion and the supporting portion for avoiding the battery pack 11 below.

[0044] A reinforcement 2 is installed at the bottom of the support beam 1, and the connecting part of the reinforcement 2 is fixed on the mounting frame. The supporting part reinforces the support beam 1 to improve the bearing capacity of the support beam 1; an avoidance space 3 is formed between the supporting part and the connecting part of the reinforcement 2, which can avoid the battery pack 11 below it, so that the top of the battery pack 11 and the bottom of the support beam 1 can be closer. At the same time, the side wall of the battery pack 11 and the mounting frame can be closer, so that a larger battery pack 11 can be installed, or a larger number of battery packs can be installed, thereby increasing the overall capacity.

[0045] In particular, Figure 2 、 Figure 4 and Figure 6 The lowermost part is a high-voltage box 13 instead of the battery pack 11 . The high-voltage box 13 is connected to the column 4 , and a fixing column (not shown) different from the column 4 may be provided corresponding to the high-voltage box 13 .

[0046] In a specific embodiment, Figure 6 As shown, a plurality of battery pack mounting positions 5 arranged longitudinally along the mounting frame form a column of battery pack accommodating chambers. In other embodiments, a plurality of support beams 1 may be fixed on the mounting frame to form a plurality of columns of battery pack accommodating chambers.

[0047] In one embodiment, Figure 1 、 Figure 2 and Figure 4 As shown, the mounting frame includes multiple columns, each column group includes multiple parallel and spaced columns 4, two support beams 1 in the support beam group are respectively fixed on two adjacent columns, and the connecting parts are fixed on the columns 4.

[0048] The support beam group is fixed on the column group, the support beam 1 is arranged vertically to the column 4, and the bottom two sides of the battery pack 11 can abut against the two support beams 1 in a support beam group. Multiple support beam groups are arranged at intervals along the height direction of the column 4. The battery pack 11 is located between the two support beams 1 in the support beam group. The column 4 is small in size and can reduce the volume of the mounting frame within a limited space to accommodate more battery packs 11.

[0049] In a specific embodiment, Figure 4 As shown, the tops of the multiple columns 4 in the same row are fixedly connected with cross bars 12 to improve the stability and firmness of the multiple columns 4.

[0050] In one embodiment, Figure 3 As shown, the support beam 1 includes a fixedly connected guide support plate 101 and a connecting plate 102. The battery pack mounting position 5 is located between two connecting plates 102 in the same support beam group. The guide support plate 101 is connected to the support portion, and the connecting plate 102 is fixedly connected to the mounting bracket. The bottom sides of the battery pack 11 slide against the two guide support plates 101 in the same support beam group. The battery pack 11 is inserted from one end of the guide support plate 101 and slides into the battery pack mounting position 5. The connecting plate 102 is fixed to the column 4, thereby fixing the position of the guide support plate 101.

[0051] In one embodiment, Figures 2 to 3 As shown, the battery pack installation position 5 is provided with an insertion end for installing the battery pack 11, and the support beam 1 also includes at least one baffle 6, which is fixed to the end of the support beam 1 away from the insertion end. The baffle 6 is used to limit the battery pack 11 in the insertion direction of the battery pack 11 to prevent the battery pack 11 from sliding out of the guide support plate 101 during installation.

[0052] In a specific embodiment, Figure 3 As shown, the baffle 6 is fixed on the connecting plate 102. In other embodiments, the baffle 6 can also be fixed on the guide support plate 101.

[0053] In one embodiment, Figure 3 As shown, the support beam 1 also includes at least one limit plate 7. One side of the limit plate 7 is fixedly connected to the side of the connecting plate 102 away from the guide support plate 101. The limit plate 7 is used to limit the vertical movement of the battery pack 11 along the mounting frame. The limit plate 7 is located above the battery pack 11 to limit the vertical movement of the battery pack 11, preventing the battery pack 11 from shaking up and down during transportation or movement, thereby colliding with other parts and causing damage to the battery pack 11.

[0054] In one embodiment, Figure 1 As shown, the end of the guide support plate 101 extends out of the mounting frame, and a clearance gap 8 for evading pipelines is formed between the end of the guide support plate 101 and the mounting frame. The arrangement of the clearance gap 8 facilitates the layout of the pipelines.

[0055] In a specific embodiment, Figure 7 As shown, the reinforcement member 2 is an L-shaped plate. The longitudinal plate 21 of the L-shaped plate serves as a connection portion fixed to the column 4, and the transverse plate 22 serves as a support portion to support the support beam 1. An escape space 3 is formed between the transverse plate 22 and the longitudinal plate 21. The arrangement of the L-shaped plate allows for a larger connection area between the support beam 1 and the longitudinal plate 21, thereby ensuring connection strength while also forming a sufficient escape space 3.

[0056] It is further explained that if Figure 8 As shown, the ends of the transverse plate 22 and the longitudinal plate 21 are connected with a reinforcing plate 27. The arrangement of the reinforcing plate 27 can improve the structural strength of the L-shaped plate, thereby achieving a better reinforcement effect on the support beam 1. The reinforcing plate 27 is arranged at an angle, and an avoidance space 3 can be formed underneath it, so that the space occupied by the reinforcement member 2 as a whole is relatively small.

[0057] It is further explained that if Figure 10 As shown, one side end of the triangular support plate 28 is fixedly connected to the surface of the horizontal plate 22, and the other side end is fixedly connected to the surface of the longitudinal plate 21. The setting of the triangular support plate enhances the strength of the L-shaped plate, thereby achieving a better support effect, and at the same time forming an avoidance space 3, and the space occupied by the reinforcement 2 as a whole is smaller.

[0058] It is further explained that the fixing plate 27 and the triangular support plate 28 can be provided on the L-shaped plate at the same time.

[0059] Regarding the structure of the reinforcement member 2, in other embodiments, as Figure 9 As shown, the reinforcement 2 can be a wedge-shaped plate having a plane 24, an inclined surface and two side surfaces 23. The two side surfaces 23 serve as connecting parts, and their bottom ends are fixedly connected to the column 4. The plane 24 serves as a supporting part to support the support beam 1, and an escape space 3 is formed below the inclined surface. Alternatively, Figure 11 As shown, the square tube is cut downward along its axial direction to form an avoidance space 3 , the fixed end 25 of the square tube is fixed on the column 4 as a connecting portion, and the longer top surface 26 serves as a supporting portion to support the support beam 1 .

[0060] According to an embodiment of the present invention, on the other hand, a battery cluster is provided, including a battery rack and a plurality of battery packs 11, the battery packs 11 are installed in the battery pack installation position 5, as shown in FIG. Figure 6 As shown, the distance H between the top of the battery pack and the bottom of the support beam 1 located above it is less than or equal to 50 mm.

[0061] It should be noted that the distance H between the top of the battery pack 11 and the bottom of the support beam 1 above it is less than or equal to 50 mm. This reduces the distance between two adjacent battery packs 11 while ensuring that the battery packs 11 can effectively dissipate heat, thereby increasing the capacity of the battery packs 11.

[0062] According to an embodiment of the present invention, on the other hand, a battery compartment is provided, comprising: a compartment body 9 and at least one battery rack or battery cluster, wherein the battery rack or battery cluster is installed in the compartment body 9 .

[0063] In a specific embodiment, a plurality of partitions are provided in the cabin 9, which divide the cabin 9 into a plurality of battery cavities. The plurality of battery cavities are each provided with a hatch. A plurality of battery racks are correspondingly installed in the plurality of battery cavities, and the plurality of hatches are each provided with a hatch door 10.

[0064] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the accompanying application.
