Technical Field

[0001] This application relates to the field of battery pack technology, and more particularly to a housing structure. Background Technology

[0002] With the development of the new energy industry, more and more vehicles are starting to use new energy.

[0003] In related technologies, new energy vehicles are powered by multiple battery packs. Each battery pack includes a housing and multiple battery modules installed inside the housing. The housing is a rectangular frame. During installation, multiple battery packs are fixed inside the vehicle, and they are often stacked in multiple layers, with multiple frames stacked sequentially.

[0004] However, the battery pack located below is prone to damage due to the low strength of the frame, which can cause the components inside the frame to be subjected to greater pressure. Utility Model Content

[0005] This application provides a box structure to solve the problem of low frame strength in the prior art.

[0006] This application provides a box structure, including:

[0007] A frame, the interior of which is used to mount a battery module;

[0008] A plurality of first support members are distributed circumferentially along the frame, and the first support members connect opposite ends of the frame in the height direction.

[0009] In one possible implementation, a bottom support is also included, the bottom support being located inside the frame and connected to the bottom of the frame.

[0010] In one possible implementation, at least one second support member is further included, which is connected to the frame and supports the lower surface of the bottom support member.

[0011] In one possible implementation, multiple second support members are provided, and the second support members are arranged sequentially at intervals along the extension direction of the frame.

[0012] In one possible implementation, the upper end of the frame is provided with an upper flange, the lower end of the frame is provided with a lower flange, and the first support member is connected to the upper flange, the lower flange, and the frame.

[0013] In one possible implementation, the first support member includes a first connecting plate, a second connecting plate, and at least two support columns, with the two ends of the support columns respectively connected to the first connecting plate and the second connecting plate;

[0014] The first connecting plate is connected to the upper flange, the second connecting plate is connected to the lower flange, and the support column is connected to the outer or inner side wall of the frame.

[0015] In one possible implementation, the support column is connected to the outer wall of the frame, and the support column has at least one connection hole.

[0016] In one possible implementation, at least one first corner support is further included, the first corner support being connected to the upper flange and the outer or inner wall of the frame, or the first corner support being connected to the lower flange and the outer or inner wall of the frame.

[0017] In one possible implementation, the first corner support includes a main body and a hollow area disposed in the middle of the main body. The main body is connected to the upper flange and the outer or inner wall of the frame, or the main body is connected to the lower flange and the outer or inner wall of the frame.

[0018] In one possible implementation, at least one second corner support is further included, which is connected to two adjacent inner sidewalls or two outer sidewalls of the frame, or the second corner support is connected to the frame and the second support.

[0019] This application provides a housing structure comprising: a frame, the interior of which is used to install battery modules; and multiple first support members distributed circumferentially along the frame, connecting opposite ends of the frame in the height direction.

[0032] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0034] In related technologies, new energy vehicles are powered by multiple battery packs. Each battery pack includes a housing and multiple battery modules installed inside the housing. The housing is typically a rectangular frame. During installation, multiple battery packs are fixed inside the vehicle, and they are often stacked in multiple layers, with multiple frames stacked sequentially.

[0035] However, under the weight of the battery pack, the lower battery pack is prone to deformation due to the lower strength of its frame. This deformation can cause the frame to exert significant pressure on its internal components (such as the battery module), potentially damaging them. For example, when the frame bulges outward, dents inward, or bends downward, it can easily put pressure on the internal components.

[0036] Therefore, this application provides a box structure, including: a frame, the interior of which is used to install battery modules; and a plurality of first support members distributed circumferentially along the frame, the first support members connecting opposite ends of the frame in the height direction. Thus, by supporting the frame with the first support members, the load-bearing capacity of the frame is improved, and the frame strength is increased. This reduces the possibility of deformation of the frame when it is under pressure, solving the problem of low frame strength in the prior art. Consequently, when multiple battery packs are stacked on top of each other, the possibility of pressure on the components inside the frame is reduced, and the possibility of damage to the components inside the frame is also reduced.

[0037] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0038] like Figure 1 As shown in the embodiment of this application, a box structure includes:

[0039] Frame 100, the interior of which is used to install the battery module;

[0040] Multiple first support members 200 are distributed circumferentially along the frame 100, and the first support members 200 connect the two opposite ends of the frame 100 in the height direction.

[0041] The frame 100 is horizontally positioned and has a rectangular outline, forming a mounting cavity on its inner side. However, the frame 100 can also have a circular or other polygonal outline; there are no limitations. In use, the battery module or other electronic components are simply installed within the frame 100 to form the complete battery pack.

[0042] Multiple first support members 200 are distributed circumferentially along the frame 100. The first support members 200 can be located on the inner side or the outer side of the frame 100. Thus, the multiple first support members 200 support the frame 100 from the direction of gravity (i.e., the height direction), thereby improving the strength and load-bearing capacity of the frame 100.

[0043] In use, the first support member 200 supports the frame 100, thereby improving the load-bearing capacity of the frame 100 and increasing the strength of the frame 100. This reduces the possibility of deformation of the frame 100 when it is under pressure, solving the problem of low strength of the frame 100 in the prior art. As a result, when multiple battery packs are stacked on top of each other, the possibility of pressure on the components (such as battery modules) inside the frame 100 can be reduced, and the possibility of damage to the components inside the frame 100 can be reduced.

[0044] Furthermore, such as Figure 1 and Figure 2 As shown, the upper end of the frame 100 is provided with an upper flange 110, and the lower end of the frame 100 is provided with a lower flange 120. The first support member 200 is connected to the upper flange 110, the lower flange 120 and the frame 100.

[0045] In this embodiment, the upper end of the frame 100 is provided with an upper flange 110, which extends outward toward the frame 100, and the extending direction of the upper flange 110 is perpendicular to the plane containing the outer wall of the frame 100. The upper flange 110 has a closed-loop structure, and the annular contour of the upper flange 110 is consistent with the annular contour of the frame 100. In practice, the upper flange 110 can be integrally formed by the frame 100, or it can be connected to the frame 100 by welding or other means.

[0046] Similarly, the lower end of the frame 100 is provided with a lower flange 120, which extends outward toward the frame 100, and the extending direction of the lower flange 120 is perpendicular to the plane containing the outer wall of the frame 100. The lower flange 120 has a closed-loop structure, and the annular contour of the lower flange 120 is consistent with the annular contour of the frame 100. In practice, the lower flange 120 can be integrally formed with the frame 100, or it can be connected to the frame 100 by welding or other means.

[0047] At this time, the first support member 200 is located on the outside of the frame 100, and the first support member 200 is connected to the upper flange 110, the lower flange 120 and the outer side wall of the frame 100. Thus, the first support member 200 supports the frame 100 from the outside, improves the strength of the frame 100, and reduces the possibility of obstructing the installation of internal components of the frame 100.

[0048] In other embodiments, the upper flange 110 and the lower flange 120 may extend toward the inside of the frame 100. In this case, the first support member 200 is correspondingly disposed on the inside of the frame 100, that is, the first support member 200 is connected to the upper flange 110, the lower flange 120 and the inner wall of the frame 100.

[0049] In some embodiments, such as Figure 2As shown, the first support member 200 includes a first connecting plate 210, a second connecting plate 220 and at least two support columns 230, with the two ends of the support columns 230 respectively connected to the first connecting plate 210 and the second connecting plate 220.

[0050] The first connecting plate 210 is connected to the upper flange 110, the second connecting plate 220 is connected to the lower flange 120, and the support column 230 is connected to the outer or inner wall of the frame 100.

[0051] In this embodiment, the first support member 200 is disposed on the outer side of the frame 100, the first connecting plate 210 is welded to the upper flange 110, and the second connecting plate 220 is welded to the lower flange 120. Two support columns 230 are provided, both of which extend vertically, and the two ends of the support columns 230 are respectively welded to the first connecting plate 210 and the second connecting plate 220, and the middle part of the support column 230 is welded to the outer wall of the frame 100.

[0052] Therefore, for the same first support member 200, the frame 100 is supported by multiple support columns 230 at the same time, and the possibility of the outer wall of the frame 100 being recessed inward is reduced.

[0053] In other embodiments, the first support member 200 may be disposed inside the frame 100, in which case the support column 230 is welded to the inner wall of the frame 100. Alternatively, the first connecting plate 210, the second connecting plate 220, and the support column 230 may be integrally formed. Of course, the first connecting plate 210 may be connected to the upper flange 110 by screwing or other means, the second connecting plate 220 may be connected to the lower flange 120 by screwing or other means, and the support column 230 may be connected to the frame 100 by screwing or other means.

[0054] Furthermore, such as Figure 1 As shown, when the support column 230 is connected to the outer wall of the frame 100, at least one connection hole 231 is provided on the support column 230.

[0055] This allows some bolts to be installed through the connection hole 231 during actual installation, connecting two adjacent battery packs without the need for additional drilling on site, thus improving the convenience of the installation process.

[0056] It should be noted that the connecting hole 231 can be an oblong hole that extends in the same direction as the support column 230, or it can be a round hole or a hole of other shapes. There are no restrictions on this.

[0057] In some embodiments, such as Figure 3 As shown, the box structure also includes a bottom support 300, which is located inside the frame 100 and is connected to the bottom of the frame 100.

[0058] It should be noted that the bottom support 300 can be a plate-like structure. The thickness of the bottom support 300 can be reasonably set according to actual needs. The bottom support 300 is set at the bottom of the frame 100 and located inside the frame 100. The edge contour of the bottom support 300 matches the contour of the frame 100 to close the mounting cavity inside the frame 100. The bottom support 300 is welded and fixed to the frame 100.

[0059] Therefore, the bottom support 300 can provide a mounting surface for the components inside the frame 100, improving the ease of component installation. In addition, the bottom support 300 also supports the frame 100 from the inside, further reducing the possibility of deformation of the frame 100 when it is subjected to external forces.

[0060] In practice, for example, the bottom support 300 can be connected to the frame 100 by friction stir welding of a profile cold plate.

[0061] In other embodiments, the bottom support 300 may be configured as a mesh structure. Alternatively, the bottom support 300 may be connected to the frame 100 by screws or other means.

[0062] In some embodiments, such as Figure 3 As shown, the box structure also includes at least one second support member 400, which is connected to the frame 100 and is supported on the lower surface of the bottom support member 300.

[0063] The second support member 400 can be a rod-shaped structure. The two ends of the second support member 400 are respectively welded to the opposite ends of the frame 100, and the second support member 400 abuts against the lower surface of the bottom support member 300. The second support member 400 can also be welded to the bottom support member 300.

[0064] In use, the second support member 400 can support the frame 100, increasing its strength and load-bearing capacity. Furthermore, the second support member 400 also provides better support for the bottom support member 300, improving its load-bearing capacity and ensuring better stability after the battery module is installed.

[0065] Specifically, such as Figure 3 As shown, multiple second support members 400 are provided, and the second support members 400 are arranged at intervals along the extension direction of the frame 100.

[0066] It should be noted that the second support member 400 extends along the width direction of the frame 100, and multiple second support members 400 are distributed sequentially at intervals along the length direction of the frame 100, so that multiple second support members 400 can support the bottom support member 300 and the frame 100 from different parts, thereby improving the strength of the frame 100.

[0067] In this embodiment, at least two second support members 400 are respectively supported at both ends of the bottom support member 300 in the length direction.

[0068] In other embodiments, the second support member 400 located at both ends of the distribution direction can also be welded to the frame 100 at its middle part to improve the stability of the connection between the second support member 400 and the frame 100.

[0069] In some embodiments, such as Figure 1 As shown, the box structure also includes at least one first corner support 500, which is connected to the outer or inner sidewall of the upper flange 110 and the frame 100, or the first corner support 500 is connected to the outer or inner sidewall of the lower flange 120 and the frame 100.

[0070] In this embodiment, multiple first corner support members 500 are provided, and all of the multiple first corner support members 500 are disposed on the outer side of the frame 100. Some of the first corner support members 500 are disposed at the upper end of the frame 100, and these first corner support members 500 are simultaneously welded to the upper flange 110 and the outer side wall of the frame 100. Other first corner support members 500 are disposed at the lower end of the frame 100, and these first corner support members 500 are simultaneously welded to the lower flange 120 and the outer side wall of the frame 100.

[0071] Thus, the first corner support member 500 supports the upper flange 110 or the lower flange 120, improving the stability of the connection between the upper flange 110 or the lower flange 120 and the frame 100; and, together with the first support member 200, it improves the overall load-bearing capacity of the frame 100.

[0072] In other embodiments, when the upper flange 110 or the lower flange 120 extends toward the inner side of the frame 100, the first corner support 500 can be connected to the inner wall of the upper flange 110 and the frame 100, or connected to the inner wall of the lower flange 120 and the frame 100. Furthermore, the first corner support 500 can also be connected to the upper flange 110, the lower flange 120, or the frame 100 by screwing or other means. The number of first corner supports 500 can be reasonably set according to actual needs and is not limited thereto.

[0073] like Figure 4As shown, the box structure also includes at least one second corner support 600, which is connected to two adjacent inner sidewalls or two outer sidewalls of the frame 100, or the second corner support 600 is connected to the frame 100 and the second support 400.

[0074] In this embodiment, multiple second corner support members 600 are provided. Some of the second corner support members 600 are welded to the two adjacent inner sidewalls of the frame 100. Alternatively, these second corner support members 600 can also be welded to the two adjacent outer sidewalls of the frame 100. This provides support for the corners of the frame 100, improving its stability and strength.

[0075] Another portion of the second corner support member 600 is correspondingly disposed on each of the second support members 400, and the second corner support member 600 is welded to the frame 100 and the second support member 400. Thus, the second corner support member 600 improves the stability of the connection between the second support member 400 and the frame 100.

[0076] In other embodiments, the second corner support 600 may be connected to the frame 100 or the second support 400 by screwing or other means.

[0077] Furthermore, such as Figure 4 As shown, the first corner support member 500 includes a main body 510 and a hollow area 520 disposed in the middle of the main body 510. The main body 510 is connected to the outer or inner wall of the upper flange 110 and the frame 100, or the main body 510 is connected to the lower flange 120 and the outer or inner wall of the frame 100.

[0078] In this embodiment, both the first corner support 500 and the second corner support 600 include a main body 510 and a hollow area 520 disposed in the middle of the main body 510.

[0079] The main body 510 can be prism-shaped, corresponding to the corner contour of the mounting surface, such as a triangular prism, a square prism, a trapezoidal prism, or other structures. The shape of the main body 510 can also be customized according to actual needs; there are no restrictions on this. The main body 510 has a hollowed-out center, forming a hollow area 520. This ensures better stability of the main body 510 while reducing material usage and lowering costs.

[0080] The mounting surface refers to the outer / inner sidewall of the frame 100, the surface of the upper flange 110, the surface of the lower flange 120, or the surface of the second support member 400.

[0081] In practice, simply place the main body 510 on the mounting surface and then weld the main body 510 to the mounting surface.

[0082] In summary, the box structure provided in this application embodiment, when in use, supports the frame 100 through the first support member 200, thereby improving the load-bearing capacity of the frame 100 and increasing the strength of the frame 100. This reduces the possibility of deformation of the frame 100 when it is subjected to pressure, solving the problem of low strength of the frame 100 in the prior art. As a result, when multiple battery packs are stacked on each other, the possibility of pressure on the components (such as battery modules) inside the frame 100 can be reduced, and the possibility of damage to the components inside the frame 100 can be reduced.
