Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a battery rack and a vehicle. Background Technology

[0002] Batteries are a crucial component of new energy vehicles, and their battery packs are typically mounted to the vehicle frame using battery racks. Because the batteries used in vehicles are relatively large and difficult to place in the middle of the frame, the battery racks are usually fixed to the sides of the vehicle's underside, near the vehicle's perimeter.

[0003] However, this area is prone to scrapes and bumps when the vehicle is driving on roads with steps or potholes. When the battery pack is subjected to a large external impact force, the battery pack may become unstable or severely deformed, which may squeeze the internal battery modules, causing electrolyte leakage and other issues that affect the normal use of the battery. Utility Model Content

[0004] This application provides a battery rack and a vehicle, which aims to improve the structural stability and impact resistance of the battery rack so as to provide impact protection for the battery pack.

[0005] The specific technical solution is as follows:

[0006] An embodiment of the first aspect of this application provides a battery rack, which includes at least two brackets arranged vertically at intervals. Each bracket includes a crossbeam and a longitudinal beam, and two adjacent longitudinal beams are fixedly connected to each other by an inner support member disposed between them.

[0007] In some embodiments, the battery rack further includes a connector, through which two adjacent brackets are connected;

[0008] Each of the brackets also includes a side beam that forms the outer contour structure of the bracket. The crossbeam and the longitudinal beam are both disposed within the outer contour structure, and both ends of the crossbeam and both ends of the longitudinal beam are connected to the side beam.

[0009] The battery rack also includes a plurality of anti-collision beams located outside the outer contour structure. The anti-collision beams extend in the vertical direction and connect two adjacent side beams, wherein at least a portion of the anti-collision beams are aligned with the crossbeams.

[0010] In some embodiments, each bracket includes at least two beams, all of which are spaced apart within the outer contour structure;

[0011] Two adjacent crossbeams are aligned with each other, and each crossbeam has a corresponding anti-collision beam at both ends. The anti-collision beam has a cavity on the side facing the side beam, and the cavity extends vertically.

[0012] In some embodiments, each bracket includes at least two longitudinal beams, all of which are spaced apart and parallel to each other, and the longitudinal beams and the crossbeams are arranged in an alternating manner.

[0013] The crossbeam passes through a portion of the longitudinal beam and is also passed through another portion of the longitudinal beam.

[0014] In some embodiments, the inner support member includes two longitudinal support rods and at least two vertical support rods;

[0015] The longitudinal support rod is connected to the longitudinal beam, and each end of the vertical support rod is fixedly connected to one of the longitudinal support rods.

[0016] In some embodiments, there are multiple inner support members, and all the inner support members are spaced apart along the extension direction of the longitudinal beam;

[0017] And / or, the number of longitudinal beams is multiple, the number of inner support members is multiple, and each longitudinal beam is provided with a number of inner support members.

[0018] In some embodiments, the bracket or the lowermost bracket further includes a side beam and a plurality of support brackets, all of which are arranged parallel to the crossbeam. Each support bracket is located between the longitudinal beam and the side beam and is fixedly connected to the longitudinal beam and the side beam respectively. Furthermore, at least a portion of the axis of the support bracket is located on the same vertical plane as the centerline of the inner support member.

[0019] In some embodiments, the battery rack further includes a plurality of mounting brackets disposed on the longitudinal beam of the uppermost bracket, all of the mounting brackets being spaced apart along the extension direction of the longitudinal beam, and each mounting bracket having a mounting hole for connecting to the vehicle frame.

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

Therefore, the terms used to describe positional relationships in the accompanying drawings are only for illustrative purposes and should not be construed as limiting this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0040] With the increasing maturity of pure electric technology and the practical need for energy conservation and emission reduction, new energy vehicles are developing rapidly, and batteries are a crucial component for these vehicles. Due to the significant energy storage requirements of vehicle batteries, the battery packs in new energy vehicles are typically large and need to be fixed to the bottom of the vehicle frame using battery racks. Due to installation limitations, battery racks cannot easily be placed in the middle of the frame; therefore, they are fixed to the bottom of the vehicle near the outer perimeter.

[0041] However, this area is prone to scrapes and bumps when the vehicle is driving on roads with steps or potholes. When the battery pack is subjected to a large external impact force, the battery pack may become unstable or severely deformed, which may squeeze the internal battery modules. In severe cases, this can lead to electrolyte leakage, fire, or even explosion, which not only affects the normal use and lifespan of the battery, but may also pose a danger to the occupants.

[0042] Based on the above, the applicant of this application has proposed a technical solution in the embodiments of this application to improve the anti-collision performance of the battery rack by improving the structure of the battery rack, thereby enhancing the protective function of the battery rack for the battery.

[0043] like Figure 1-6 As shown, an embodiment of the first aspect of this application provides a battery rack, which includes at least two brackets 20 arranged vertically at intervals, each bracket 20 including a crossbeam 22 and a longitudinal beam 23.

[0044] Specifically, the battery rack's brackets 20 are used to place battery modules, and each bracket 20 can hold multiple battery modules. For example, when the battery rack includes two brackets 20, multiple battery modules can be placed on the two brackets 20 in layers. This embodiment uses a battery rack with two brackets 20 as an example, but in other embodiments, the battery rack can also be configured to include more than two brackets 20.

[0045] Furthermore, it should be noted that the "up and down" direction mentioned in this embodiment refers to the vertical direction perpendicular to the horizontal plane when the battery rack is installed horizontally at the bottom of the vehicle frame. In other words, at least two brackets 20 arranged vertically at intervals are at least two brackets 20 arranged in the vertical direction.

[0046] The bracket 20 includes a crossbeam 22 and a longitudinal beam 23, which can be arranged in an alternating manner to form a placement plane for placing the battery module. Furthermore, the alternating arrangement of the crossbeam 22 and the longitudinal beam 23 can also ensure the structural strength of the bracket 20, guaranteeing its support effect and impact resistance.

[0047] Furthermore, the two adjacent longitudinal beams 23 are fixedly connected to each other by an inner support member 40 located between them. Since the inner support member 40 is fixedly supported between the two longitudinal beams 23, it provides vertical support and impact resistance. When the longitudinal beam 23 of the bottom bracket 20 is impacted, the inner support member 40 not only resists the external impact force to a certain extent, but also disperses the impact force towards the adjacent brackets 20, thereby further ensuring the structural strength and impact resistance of the bottom of the bracket 20 and further enhancing the overall impact resistance of the battery rack.

[0048] In summary, the battery rack provided in this embodiment includes at least two brackets 20 arranged vertically at intervals. Each bracket 20 includes a crossbeam 22 and a longitudinal beam 23. The two adjacent longitudinal beams 23 are fixedly connected to each other by an inner support member 40 located between them. In this way, the inner support member 40 achieves overall connection and support of the battery rack, thereby improving the overall impact resistance of the battery rack. When the longitudinal beam 23 of the bottom bracket 20 is impacted, the longitudinal beam 23 can resist the external impact force to a certain extent through the inner support member 40. Furthermore, the impact force can also be dispersed towards the adjacent brackets 20 through the inner support member 40, thereby further ensuring the structural strength and impact resistance of the bottom of the bracket 20. Therefore, the structural stability and anti-collision performance of the battery rack are greatly improved, thus providing better anti-collision protection for the battery pack.

[0049] like Figure 2 As shown, in some embodiments, the battery rack also includes several mounting brackets 60, which are disposed on the longitudinal beam 23 of the uppermost bracket 20. All mounting brackets 60 are arranged at intervals along the longitudinal beam 23, and each mounting bracket 60 has a mounting hole for connecting to the vehicle frame.

[0050] After the battery module is fixed on the bracket 20, the entire battery rack is then mounted and fixed to the bottom of the vehicle frame via the top mounting bracket 60. For example, the mounting bracket 60 may use a mounting rod that extends vertically, and the mounting bracket 60 is fixedly connected to the vehicle frame via mounting holes formed on its surface using fasteners.

[0051] In other feasible methods, the mounting bracket 60 can also be installed and fixed to the vehicle frame by welding. To ensure installation stability, multiple mounting brackets 60 can be provided, and the multiple mounting brackets 60 are evenly distributed on the battery rack, thereby connecting and fixing the battery rack to the vehicle frame at multiple points.

[0052] like Figure 2 and Figure 4 As shown, in some embodiments, the battery rack also includes a connector 10, and two adjacent brackets 20 are connected by the connector 10.

[0053] Since the battery module is placed on the bracket 20, in order to ensure the connection stability between two adjacent brackets 20, the connector 10 can be arranged at intervals along the circumference of the bracket 20, so as to make the connection strength between two adjacent brackets 20 higher and to ensure the support strength at each position of the bracket 20.

[0054] For example, connector 10 can use a plate-like structure, such as Figure 4As shown in the diagram, the connector 10 is designed as a plate structure. On the one hand, it allows for a longer connection surface with the bracket 20 to ensure connection strength. On the other hand, it also provides some protection on the side of the battery rack to prevent large objects, such as stones, from hitting the battery modules inside the battery rack and causing damage to the battery modules.

[0055] In specific implementations, in some embodiments, the multi-layer brackets 20 can be connected by a single connector 10. That is, the height of the connector 10 is adapted to the overall height of the battery rack, thereby further improving the structural stability of the battery rack in the height direction. In other embodiments, a single connector 10 can connect only two adjacent brackets 20, allowing the connectors 10 to be staggered at adjacent positions, thus achieving a tighter connection. Furthermore, the connector 10 and the bracket 20 can be connected by welding or bolts.

[0056] Furthermore, each bracket 20 includes a side beam 21, which forms the outer contour structure of the bracket 20. The cross beam 22 and the longitudinal beam 23 are both located within the outer contour structure, and both ends of the cross beam 22 and the two ends of the longitudinal beam 23 are connected to the side beam 21.

[0057] In other words, the outer contour structure enclosed by the side beams 21 is the shape of the bracket 20 used to place the battery module, such as a rectangle. In this embodiment, a rectangle is used as an example to illustrate the outer contour structure.

[0058] In a practical implementation, the side beam 21 can include four sub-side beams, which are connected end to end to form a rectangular structure. Based on this, the crossbeam 22 is placed within the outer contour structure, and both ends of the crossbeam 22 are connected to the side beam 21. For example, the two ends of the crossbeam 22 can be connected to two oppositely positioned sub-side beams, thus enabling the crossbeam 22 to provide a certain degree of support between the two opposite sub-side beams.

[0059] Furthermore, the battery rack also includes a plurality of anti-collision beams 30 located outside the outer contour structure. The anti-collision beams 30 extend in the vertical direction and connect to two adjacent side beams 21, wherein at least a portion of the anti-collision beams 30 are aligned with the crossbeams 22.

[0060] This can be understood as follows: on the plane where a crossbeam 22 is located, two anti-collision beams 30 can extend vertically from the side beam 21 of the bracket 20 until they connect with the side beam 21 on the adjacent bracket 20. In this way, when the anti-collision beam 30 is hit from the side, since the anti-collision beam 30 is aligned with the crossbeam 22, that is, the anti-collision beam 30 is supported by the crossbeam 22, a part of the force applied to the anti-collision beam 30 can be distributed to the crossbeam 22, thereby transmitting and dispersing the force. Compared with the case where the anti-collision beam 30 bears the impact force alone, the deformation of the anti-collision beam 30 is smaller and the impact force that it can withstand is greater.

[0061] For example, when arranging the crossbeam 22 and the anti-collision beam 30, their positions can be adjusted according to the actual situation, such as specifically for parts that are prone to impact.

[0062] In some embodiments, the battery rack may be made of low-alloy high-strength steel. Using low-alloy high-strength steel for the battery rack results in greater structural strength and impact resistance, making it less prone to deformation and damage when subjected to external impacts or pressure.

[0063] Low-alloy high-strength steel specifically refers to low-alloy engineering structural steel in which a small amount of alloying elements are added to low-carbon steel, resulting in a yield strength exceeding 275 MPa in the rolled or normalized state. Low-alloy high-strength steel possesses high strength and high load-bearing capacity while also exhibiting relatively light weight.

[0064] For example, the battery rack can be made of Q355B steel, and the side connecting plates can be made of 700L steel, so as to ensure that the steel plates can withstand greater forces during the stretching process without breaking, and can maintain good integrity when subjected to impact or bending.

[0065] like Figure 1 As shown, in some embodiments, the bracket 20 includes at least two crossbeams 22, all of which are spaced apart within the outer contour structure. Furthermore, adjacent crossbeams 22 are aligned with each other, and each crossbeam 22 has a corresponding anti-collision beam 30 at both ends.

[0066] This configuration allows the two corresponding crossbeams 22 and the two anti-collision beams 30 to jointly form a frame-like support structure. In other words, not only do the increased number of crossbeams 22 provide better support for the outer contour structure of the bracket 20, enhancing its support strength, but the combined effect of multiple crossbeams 22 and multiple anti-collision beams 30 creates a larger number of frame-like support structures, further increasing the protective density of the battery rack and thus enhancing its protective capabilities.

[0067] Furthermore, since the bottom crossbeam 22 and side beam 21 of the battery rack are both supported by the anti-collision beam 30, when the battery rack is impacted from the bottom, a portion of the force applied to the bottom crossbeam 22 and a portion of the force applied to the bottom side beam 21 can be distributed to the anti-collision beam 30, thereby further enhancing the impact resistance of the bottom crossbeam 22 and side beam 21 of the battery rack to a certain extent.

[0068] See Figure 1 As shown, for example, in addition to connecting a crash beam 30 to both ends of each crossbeam 22, a separate crash beam 30 can also be set to connect between the side beams 21 of two adjacent brackets 20. This can achieve a tighter wrapping of the side of the battery rack, and the crash beam 30 can further play a certain degree of impact resistance in some areas not covered by the frame-shaped support structure of the side beam 21.

[0069] In one feasible approach, in addition to the anti-collision beams 30 that form a frame-like support structure with the crossbeams 22, all other anti-collision beams 30 can be symmetrically arranged along the transverse centerline of the battery rack. This not only further enhances the structural strength and stability of the battery rack through the installation of the anti-collision beams 30, but also provides broader and more comprehensive protection for the entire battery rack.

[0070] Furthermore, such as Figure 3 As shown, in some embodiments, a cavity 31 is formed on the side of the anti-collision beam 30 facing the side beam 21, and the cavity 31 extends vertically. This arrangement allows the cavity 31 on the anti-collision beam 30 to form an energy-absorbing cavity. When the anti-collision beam 30 is subjected to an external impact, part of the energy absorption can be achieved through the collapse deformation of the anti-collision beam 30 towards the interior of its cavity 31, thereby further improving the impact resistance of the frame support structure formed by the anti-collision beam 30 and the crossbeam 22.

[0071] In practice, the anti-collision beam 30 can be configured as a rectangular tube, a "U"-shaped tube, a "C"-shaped tube, a circular tube, or other structural forms. The connection between the anti-collision beam 30 and the crossbeam 22 can be achieved by welding, for example, to further ensure connection strength and structural stability.

[0072] For example, each bracket 20 can also be provided with multiple longitudinal beams 23. This arrangement provides better support capacity, higher structural stability, and higher structural strength for the bracket 20, thereby improving its impact resistance. In a specific arrangement, all longitudinal beams 23 are spaced apart and parallel to each other. Furthermore, the crossbeams 22 and longitudinal beams 23 can be arranged in an alternating pattern.

[0073] In this configuration, the crossbeam 22 passes through a portion of the longitudinal beam 23 and is also passed through another portion of the longitudinal beam 23. In other words, the crossbeam 22 and the longitudinal beam 23 can be interwoven in a continuous manner; see [reference needed] for details. Figure 1 As shown. That is to say, a notch is made at the intersection of the crossbeam 22 and the longitudinal beam 23, for example, a notch is made on the crossbeam 22 to allow the longitudinal beam 23 to pass through, or a notch is made on the longitudinal beam 23 to allow the crossbeam 22 to pass through.

[0074] This design not only makes the placement surface of the battery module formed by the longitudinal beam 23 and the cross beam 22 of the bracket 20 flatter, thus ensuring the structural stability of the battery module after placement, but also enhances the structural integrity of the cross beam 22 and the longitudinal beam 23, making it easier to transmit and disperse forces at the intersection of the cross beam 22 and the longitudinal beam 23.

[0075] For example, in some embodiments, the number of inner support members 40 can be set to multiple, and all inner support members 40 are spaced apart along the extension direction of the longitudinal beam 23, which can further improve the overall structural strength of the battery rack. Alternatively, for example, all inner support members 40 can be distributed on all longitudinal beams 23.

[0076] like Figure 5 and Figure 6 As shown, in some embodiments, the inner support member 40 includes two longitudinal support rods 41 and at least two vertical support rods 42. The longitudinal support rods 41 are connected to the longitudinal beam 23, and each vertical support rod 42 is fixedly connected to a longitudinal support rod 41 at both ends.

[0077] By including two longitudinal support rods 41 and at least two vertical support rods 42 in the inner support member 40, the inner support member 40 can form a frame-type support structure, which makes the structure more stable and has a stronger ability to bear forces.

[0078] In practice, the longitudinal support rod 41 and the vertical support rod 42 can together form a trapezoidal structure or a square structure to further ensure structural stability. In some embodiments, the longitudinal support rod 41 and the vertical support rod 42 can also be integrally formed to further increase structural strength. In addition, the inner support member 40 can also be made of the same material as the anti-collision beam 30.

[0079] like Figure 1 As shown, in some embodiments, the bracket 20 or the lowermost bracket 20 further includes several support brackets 24. All support brackets 24 are arranged parallel to the crossbeam 22, and each support bracket 24 is disposed between the longitudinal beam 23 and the side beam 21 and fixedly connected to them respectively. This arrangement can further enhance the structural strength of the bracket 20 through the support brackets 24, not only strengthening its surface support force, but also improving the structure's impact resistance and range.

[0080] In this embodiment, the support bracket 24 is set on the lowest bracket 20 as an example. Of course, in other embodiments, the support bracket 24 can be set on all brackets 20.

[0081] In other possible implementations, when the bracket 20 also includes multiple longitudinal beams 23, the support bracket 24 can also be set between adjacent longitudinal beams 23 on both sides, thereby further enhancing the structural strength of the bracket 20.

[0082] For example, the number of support brackets 24 can be set to multiple, and all support brackets 24 are arranged at intervals on the outer contour structure enclosed by the side beams 21 of the bracket 20. This arrangement can further enhance the structural strength of the bracket 20.

[0083] Figure 2 In one example of the arrangement of the support brackets 24, support brackets 24 can be installed between multiple crossbeams 22, and between the crossbeams 22 and the side beams 21 near the side beams 21. In this case, the support brackets 24 can extend along the same straight line to connect the side beams 21 and all crossbeams 22 in a through-type manner. Simultaneously, support brackets 24 can be further installed between the longitudinal beams 23 and the side beams 21, thereby maximizing the number of support brackets 24 to improve the overall structural strength of the battery rack. Of course, in other embodiments, other arrangements of the support brackets 24 can also be used.

[0084] For example, in one possible implementation, the axis of a portion of the support bracket 24 may be located in the same vertical plane as the centerline of the inner support member 40. In this way, the forces acting on the support bracket 24 can be dispersed through the inner support member 40, thereby further improving the impact resistance of the battery rack.

[0085] For example, the support bracket 24 can also adopt a rectangular tube, a "U"-shaped tube, a "C"-shaped tube, or a round tube. This can also form a crumple space on the support bracket 24. When the support bracket 24 is subjected to external impact force, it can absorb part of the force through its own deformation, thereby further protecting the battery module located inside the battery rack.

[0086] like Figure 2 As shown, in some embodiments, the battery rack further includes several cover plates 50, which cover the top of the battery rack. The cover plates 50 on the top of the battery rack can provide a certain degree of protection for the battery modules, preventing the battery pack from being squeezed from above or from being hit by flying stones. In some embodiments, the cover plates 50 can also cover the bottom of the battery rack. This arrangement can also further protect the bottom of the battery pack. For example, the cover plates 50 can be made of steel plates to ensure a certain degree of impact resistance.

[0087] Since the top layer of the battery rack is usually fixed to the vehicle frame, it is less likely to be affected by external impacts. Therefore, in this embodiment, the top cover plate 50 is made of a flexible material, such as alloy spring steel or rubber, to provide protection while minimizing structural weight.

[0088] Furthermore, a buffer cavity can be provided between the cover plate 50 and the battery rack, so that when the battery rack is impacted from the bottom or top, a certain amount of deformation can be absorbed through the buffer cavity, thereby protecting the internal structure of the battery rack.

[0089] An embodiment of the second aspect of this application provides a vehicle that includes the battery rack from any of the above embodiments. The battery rack is used to secure itself to the vehicle, specifically to the bottom of the vehicle frame.

[0090] In this embodiment, when the bottom of the battery rack is impacted during vehicle operation, the inner support member 40 not only resists the external impact force to a certain extent, but also disperses the impact force towards the adjacent bracket 20 through the inner support member 40, thereby further ensuring the structural strength and impact resistance of the bottom of the bracket 20, further improving the overall impact resistance of the battery rack, and thus providing better anti-collision protection for the battery pack.

[0091] It should be noted that the vehicle provided in this embodiment should also include other modules or components that enable the vehicle to operate normally. Here, the other modules or components included in the vehicle provided in this embodiment will not be described one by one.

[0092] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
