[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] In view of the problem of poor protective performance of bottom protective plates in related technologies, this utility model provides a bottom protective plate to improve protection and meet the protection performance of batteries.

[0038] like Figure 1 and Figure 2 As shown, the bottom protective plate includes a protective plate 1 and a reinforcing structure. The reinforcing structure is located at the bottom of the protective plate 1 and connected to the protective plate 1. The reinforcing structure includes at least one first reinforcing component 2 and at least one second reinforcing component 3. The first reinforcing component 2 includes a first reinforcing member 21 and a first substrate 22. The first substrate 22 has a first mounting groove 221 on its side facing the protective plate 1. The first reinforcing member 21 is located in the first mounting groove 221. The second reinforcing component 3 includes at least a second substrate 32. The first substrate 22 and the second substrate 32 are stacked and connected.

[0039] The reinforcing structure of the bottom guard plate provided by this utility model includes at least a first reinforcing component 2 and a second reinforcing component 3. Since the first reinforcing component 2 includes a first reinforcing member 21 and a first substrate 22, and the second reinforcing component 3 includes at least a second substrate 32, the first substrate 22 and the second substrate 32 are stacked and connected. This arrangement can improve the overall strength of the bottom guard plate and reduce the damage to the internal structure of the battery pack caused by external impact after being impacted, thereby reducing the deformation of the bottom guard plate when impacted. Compared with the existing technology where the bottom guard plate is provided with a single-layer reinforcing member, the strength of the bottom guard plate is improved, thereby reducing the amount of deformation of the bottom guard plate and meeting the protection requirements of the battery.

[0040] The aforementioned bottom protection plate offers excellent comprehensive protection, is lightweight, low-cost, and space-saving.

[0041] In addition, the protective plate 1, the first substrate 22 and the second substrate 32 are all complete plate structures, which can improve the rigidity of the bottom protective plate.

[0042] Furthermore, the second reinforcing component 3 also includes a second reinforcing member 31, and the second substrate 32 is provided with a second mounting groove, within which the second reinforcing member 31 is located. This staggered arrangement of the second reinforcing member 31 and the first reinforcing member 21 improves the overall strength of the bottom protective plate.

[0043] Specifically, the second substrate 32 is provided with a second mounting groove on the side wall facing the protective plate 1, and the first substrate 22 is provided with a first mounting groove 221 on the side wall facing the protective plate 1. This arrangement can prevent the first reinforcing member 21 from separating from the first substrate 22 and the second reinforcing member 31 from the second substrate 32 after the bottom protective plate is impacted, thereby improving the stability of the reinforcing structure.

[0044] Furthermore, the length of the first reinforcing member 21 extends along the first direction, and the length of the second reinforcing member 31 extends along the second direction, with the first and second directions forming an angle. In this way, the first reinforcing member 21 and the second reinforcing member 31 overlap at least partially in the height direction of the bottom guard plate, thereby improving the overall strength of the bottom guard plate and reducing the amount of deformation of the bottom guard plate after being impacted.

[0045] For example, the angle between the first direction and the second direction is 90 degrees, that is, the first direction and the second direction are perpendicular. Exemplarily, the first direction is the X direction and the second direction is the Y direction. Of course, in other embodiments, the first direction is the Y direction and the second direction is the X direction. This arrangement ensures that the first reinforcing member 21 and the second reinforcing member 31 can at least partially overlap in the Z direction, further improving the overall structural performance, thereby improving the overall strength of the bottom protective plate and meeting the battery protection requirements.

[0046] In some embodiments, such as Figure 2As shown, the thickness of the protective plate 1 is set as d1, where 0.2mm < d1 < 3mm; for example, the value of d1 can be 1mm, 1.5mm, 2mm or 2.5mm, and is not specifically limited in this embodiment. When d1 is 1mm, the overall thickness of the bottom protective plate can be reduced, reducing the space occupied by the bottom protective plate. When d1 is 2.5mm, the thickness of the bottom protective plate can be increased, increasing the load-bearing capacity of the bottom protective plate, increasing the overall strength of the protective plate 1, and reducing the deformation of the protective plate 1.

[0047] The thickness of the first reinforcing member 21 and the thickness of the second reinforcing member 31 are both d2, where 0.5mm < d2 < 6mm. For example, d2 can be 0.6mm, 1mm, 2mm, 3mm, 4mm or 5mm. In this embodiment, no specific limitation is made. When d2 is 1mm, the overall thickness of the bottom guard plate can be reduced, and the space occupied by the bottom guard plate can be reduced. When d2 is 5mm, the thickness of the bottom guard plate can be increased, the load-bearing capacity of the bottom guard plate can be increased, the overall strength of the first reinforcing member 21 and the second reinforcing member 31 can be increased, and the deformation of the first reinforcing member 21 and the second reinforcing member 31 can be reduced.

[0048] In some embodiments, the thickness of the first substrate 22 and the thickness of the second substrate 32 are both d3, where 0.1mm < d3 < 10mm. For example, d3 is 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm or 9mm. When d3 is 1mm, the overall thickness of the bottom protective plate can be reduced, and the space occupied by the bottom protective plate can be reduced. At this time, d2 is 0.6mm, which can ensure that the first substrate 22 and the second substrate 32 are processed with corresponding grooves to embed the first reinforcing member 21 and the second reinforcing member 31 in the corresponding reinforcing member. When d3 is 10mm, the thickness of the bottom protective plate can be increased, thereby increasing the strength of the substrate and reducing the overall deformation of the substrate.

[0049] In some embodiments, along the thickness direction (i.e., the Z direction) of the bottom protective plate, the protective plate 1, the first reinforcing component 2 and the second reinforcing component 3 are stacked sequentially from top to bottom, and the first reinforcing component 2 is located between the protective plate 1 and the second reinforcing component 3 and is fixedly connected to the protective plate 1 and the second reinforcing component 3 respectively.

[0050] In other embodiments, there are two or more first reinforcing components 2 or second reinforcing components 3, and the second reinforcing components 3 are interconnected with the first reinforcing components 2. For example, a second reinforcing component 3 is disposed between two first reinforcing components 2, and a first reinforcing component 2 is disposed between two second reinforcing components 3, and the first reinforcing components 2 and the second reinforcing components 3 are interconnected.

[0051] In some embodiments, the first substrate 22 has a plurality of first mounting grooves 221, and correspondingly, the number of first reinforcing members 21 is also plurality of. Each of the plurality of first reinforcing members 21 is arranged in a one-to-one correspondence with a plurality of first mounting grooves 221. This reduces the overall material area of ​​the first reinforcing members 21, lowering manufacturing costs. Especially for locations prone to impact, larger areas of the first reinforcing members 21 can be provided to improve local strength and reduce deformation. Specifically, the first reinforcing members 21 are embedded within the first mounting grooves 221. The first reinforcing members 21 can be embedded through integral injection molding or compression molding processes. The first reinforcing component 2 and / or the second reinforcing component 3 are integral structures. For example, the first reinforcing member 21 is a metal plate, which can be placed in a molding die and then formed through injection molding, compression molding, or RTM processes to obtain the first reinforcing component 2. The second reinforcing component 3 is also obtained using the same method.

[0052] In some embodiments, the second substrate 32 has a plurality of second mounting slots, and correspondingly, the number of second reinforcing members 31 is also plurality of. Each of the plurality of second reinforcing members 31 is arranged in a one-to-one correspondence with a plurality of second mounting slots. This reduces the overall material area of ​​the second reinforcing members 31, lowering manufacturing costs. Especially for locations prone to impact, larger areas of second reinforcing members 31 can be provided to improve local strength and reduce deformation. Specifically, the second reinforcing members 31 are embedded in the second mounting slots. The second reinforcing members 31 can be embedded through integral injection molding or compression molding processes. For example, the second reinforcing member 31 is a metal plate, which can be first placed in a molding die and then formed through injection molding, compression molding, or RTM processes to obtain the second reinforcing component 3.

[0053] In some embodiments, the protective plate 1, the first reinforcing member 21, the first substrate 22, the second reinforcing member 31, and the second substrate 32 are all metal plates or composite material plates. For example, when the protective plate 1, the first reinforcing member 21, the first substrate 22, the second reinforcing member 31, and the second substrate 32 are all metal plates, the metal plates can specifically be steel plates, aluminum alloy plates, or magnesium alloy plates, which can improve the structural strength and rigidity of the protective plate 1, the first reinforcing member 21, the first substrate 22, the second reinforcing member 31, and the second substrate 32.

[0054] When the protective plate 1, the first reinforcing member 21, the first substrate 22, the second reinforcing member 31, and the second substrate 32 are all composite material plates, the composite material plates can be epoxy resin plates, vinyl ester resin plates, or polyurethane plates, etc. Alternatively, other non-composite polymer material plates, such as PEEK or PPO, can also be used. This allows the protective plate 1, the first reinforcing member 21, the first substrate 22, the second reinforcing member 31, and the second substrate 32 to possess good toughness, providing flexible protection under bottom impact conditions.

[0055] It should be noted that the materials of the protective plate 1, the first reinforcing member 21, the first substrate 22, the second reinforcing member 31, and the second substrate 32 can be adjusted, and can be adjusted according to different working conditions.

[0056] In some embodiments, a portion of the protective plate 1, the first reinforcing member 21, the first substrate 22, the second reinforcing member 31, and the second substrate 32 is a metal plate, and the other portion is a composite material plate. Exemplarily, both the protective plate 1 and the second substrate 32 are metal plates, while the first reinforcing member 21, the first substrate 22, and the second reinforcing member 31 are composite material plates. With this configuration, the bottom protective plate possesses strong comprehensive mechanical properties. In other embodiments, the protective plate 1, the first reinforcing member 21, and the second reinforcing member 31 are all metal plates, while the first substrate 22 and the second substrate 32 are both composite material plates.

[0057] In some embodiments, reinforcing ribs 4 are provided in at least one of the protective plate 1, the first reinforcing member 21, the first substrate 22, the second reinforcing member 31, and the second substrate 32, such as... Figure 3 As shown, a reinforcing rib 4 is provided on the first substrate 22. The reinforcing rib 4 is obtained through topology optimization. The topology-optimized reinforcing rib 4 can improve the overall structural rigidity of the bottom cover plate, so that the bottom cover plate can better protect the battery cell from impact damage and cause safety accidents.

[0058] This utility model also provides a battery box, which includes a main body and a bottom protective plate provided in this embodiment. The bottom protective plate is located at the bottom of the main body and is fixedly connected to the main body. The bottom protective plate provided in this embodiment has a reinforcing structure including at least a first reinforcing component 2 and a second reinforcing component 3. The first reinforcing component 2 includes a first reinforcing member 21 and a first substrate 22, and the second reinforcing component 3 includes a second reinforcing member 31 and a second substrate 32. The first substrate 22 and the second substrate 32 are stacked and connected. Thus, the first reinforcing member 21 and the second reinforcing member 31 are staggered along the height direction of the bottom protective plate, thereby improving the overall strength of the bottom protective plate. This reduces the deformation of the bottom protective plate upon impact and improves its overall strength. Compared to the prior art where the bottom protective plate has a single-layer reinforcing member, this method improves the strength of the bottom protective plate, thereby reducing the deformation and meeting the battery protection requirements.

[0059] This utility model also provides a battery pack, such as Figure 4As shown, the battery pack includes a battery module 20 and a battery housing provided in this embodiment of the invention. The battery module 20 is disposed within the battery housing, and the bottom protective plate 10 is located at the bottom of the battery module 20. Since the battery housing includes the bottom protective plate 10, and since the bottom protective plate 10 provided in this embodiment of the invention has a reinforcing structure including at least a first reinforcing component 2 and a second reinforcing component 3, the first reinforcing component 2 includes a first reinforcing member 21 and a first substrate 22, and the second reinforcing component 3 includes a second reinforcing member 31 and a second substrate 32. The first substrate 22 and the second substrate 32 are stacked and connected. Thus, the first reinforcing member 21 and the second reinforcing member 31 are staggered along the height direction of the bottom protective plate 10, thereby improving the overall strength of the bottom protective plate 10. This reduces the deformation of the bottom protective plate 10 upon impact, and improves the overall strength of the bottom protective plate 10. Compared to the prior art where the bottom protective plate 10 has a single-layer reinforcing member, this method improves the strength of the bottom protective plate 10, thereby reducing the deformation of the bottom protective plate 10 and meeting the battery protection requirements.

[0060] This utility model also provides a vehicle including a battery pack provided in an embodiment of this utility model. Since the battery pack includes a bottom protection plate 10, and the bottom protection plate 10 provided in this embodiment has a reinforcing structure including at least a first reinforcing component 2 and a second reinforcing component 3, the first reinforcing component 2 includes a first reinforcing member 21 and a first substrate 22, and the second reinforcing component 3 includes a second reinforcing member 31 and a second substrate 32. The first substrate 22 and the second substrate 32 are stacked and connected. Thus, the first reinforcing member 21 and the second reinforcing member 31 are staggered along the height direction of the bottom protection plate 10, thereby improving the overall strength of the bottom protection plate 10. This reduces the deformation of the bottom protection plate 10 upon impact, and improves the overall strength of the bottom protection plate 10. Compared to the prior art where the bottom protection plate 10 has a single-layer reinforcing member, this improves the strength of the bottom protection plate 10, thereby reducing the deformation of the bottom protection plate 10 and meeting the battery protection requirements.
