Description

Technical Field

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

[0002] In mining vehicles, the battery support frame is a structure used to install batteries. It not only needs to bear the weight of the batteries, but also needs to provide stable and reliable structural support and protection during the operation of the mining vehicle.

[0003] Due to the complex road environment in mining areas, which is mostly unpaved roads such as potholes, gravel, and slopes, mining vehicles generate continuous and severe vibration and impact loads during operation. At the same time, under emergency braking, sudden stopping, or heavy-load conditions, the battery is subjected to significant inertial impact forces. These dynamic loads are directly transmitted to the battery support frame, causing it to be in a state of combined vibration fatigue and impact loads for a long time.

[0004] In related technologies, battery load-bearing frames are typically constructed by welding multiple beams or profiles. Under long-term vibration and impact loads, stress concentration easily occurs at the welds, leading to fatigue cracks and even structural breakage. This severely impacts the reliability of the battery load-bearing frame, thereby affecting the product's economic efficiency. Therefore, effectively improving the reliability of battery load-bearing frames is an ongoing research direction. Summary of the Invention

[0005] In view of the above problems, this application provides a battery support frame and a mining vehicle, which can effectively improve the reliability of the battery support frame.

[0006] In a first aspect, embodiments of this application provide a battery support frame, which includes a support body and reinforcing components. The support body includes multiple support portions spaced apart along a first direction, with a first accommodating space for accommodating a battery formed between adjacent support portions. Each support portion includes a first main beam and a second main beam, both extending along a second direction and spaced apart along a third direction. The first, second, and third directions intersect each other. Reinforcing components connect adjacent support portions and include a reinforcing plate, a first longitudinal beam, and a second longitudinal beam. The first longitudinal beam connects the first main beams of adjacent support portions, the second longitudinal beam connects the second main beams of adjacent support portions, and the reinforcing plate connects the first and second longitudinal beams.

[0007] In some embodiments of the first aspect, the reinforcing plate has an opening that penetrates the reinforcing plate in a third direction.

[0008] In some embodiments of the first aspect, the first main beam protrudes from the side surface of the first longitudinal beam opposite to the reinforcing plate, so as to form a second receiving space for accommodating the wire harness on the side of the first longitudinal beam opposite to the reinforcing plate.

[0009] In some embodiments of the first aspect, a wiring hole is provided on the reinforcing plate, and the wiring hole penetrates the reinforcing plate in a third direction.

[0010] In some embodiments of the first aspect, the reinforcing plate is provided with a first rib, which connects the first longitudinal beam and the second longitudinal beam.

[0011] In some embodiments of the first aspect, the load-bearing portion further includes a first crossbeam connected between the first main beam and the second main beam. A reinforcing plate is connected between the first crossbeams of two adjacent load-bearing portions.

[0012] In some embodiments of the first aspect, the load-bearing portion further includes a first reinforcing beam connecting the first main beam and the first crossbeam; and / or, the load-bearing portion further includes a second reinforcing beam connecting the second main beam and the first crossbeam.

[0013] In some embodiments of the first aspect, the supporting body further includes a side beam extending along a first direction, connecting multiple supporting parts, and located at the end of the supporting parts along a second direction. The side beam includes a beam body and a reinforcing member. The beam body includes a first wall, a second wall, and a third wall. The first and second walls are disposed opposite each other along the second direction. The third wall connects between the first and second walls and is disposed close to the first accommodating space along a third direction. The reinforcing member connects between the first and second walls and is disposed opposite to the third wall along a third direction. The projected area of ​​the reinforcing member along the third direction is smaller than the projected area of ​​the third wall along the third direction.

[0014] In some embodiments of the first aspect, the reinforcing plate includes a first plate body and a second plate body, the first plate body and the second plate body are disposed opposite to each other and spaced apart along a second direction, and an energy-absorbing cavity is formed between the first plate body and the second plate body.

[0015] Secondly, embodiments of this application provide a mining vehicle, which includes the battery support frame of any of the above solutions.

[0016] The battery load-bearing frame provided in this application, by incorporating reinforcing components between adjacent load-bearing parts, enables the reinforcing plate, first main beam, second main beam, first longitudinal beam, and second longitudinal beam to form a closed box-shaped frame structure, creating an equivalent closed force loop. This significantly improves the bending and torsional resistance of the battery load-bearing frame. The first and second longitudinal beams form an effective force transmission path in the first direction between adjacent load-bearing parts, reducing local deflection and fatigue stress concentration in individual load-bearing parts and improving long-term durability. The reinforcing plate provides resistance to shear forces under torsional conditions, giving the entire battery load-bearing frame stronger shear and torsional resistance, thereby reducing torsional deformation under complex road conditions or impacts and effectively improving the reliability of the battery load-bearing frame.

[0028] The battery support frame provided in the embodiments of this application will be described below with reference to the accompanying drawings. Figure 1 This is a three-dimensional structural diagram of a battery support frame provided in some embodiments of this application. Figure 2 This is a top view schematic diagram of a battery support frame provided in some embodiments of this application. Figure 3 A battery support frame provided for some embodiments of this application along Figure 2 A schematic diagram of the cross-sectional structure of AA in the diagram.

[0029] refer to Figures 1 to 3 This application provides a battery support frame, which includes a support body 10 and reinforcing members 20. The support body 10 includes multiple support sections 11, which are spaced apart along a first direction X. A first accommodating space 12 for accommodating a battery is formed between two adjacent support sections 11. Each support section 11 includes a first main beam 111 and a second main beam 112, both of which extend along a second direction Y. The first main beam 111 and the second main beam 112 are spaced apart along a third direction Z, and the first direction X, the second direction Y, and the third direction Z intersect each other. The reinforcing members 20 are connected between two adjacent support sections 11. The reinforcing members 20 include a reinforcing plate 21, a first longitudinal beam 22, and a second longitudinal beam 23. The first longitudinal beam 22 connects between the first main beams 111 of two adjacent support sections 11, and the second longitudinal beam 23 connects between the second main beams 112 of two adjacent support sections 11. The reinforcing plate 21 connects between the first longitudinal beam 22 and the second longitudinal beam 23.

[0030] The supporting body 10 is used to provide the supporting foundation and installation reference for the battery, and its whole can be a frame structure.

[0031] Optionally, the first main beam 111 and the second main beam 112 can be made of high-strength steel, aluminum alloy or composite materials to balance load-bearing strength and lightweight requirements.

[0032] The dimensions of the first accommodating space 12 can be designed to match the shape of the battery. Its boundary can be defined by the beam of the adjacent support part 11 and the necessary transverse connecting parts, thereby forming a regular and assemblable battery installation area within the support body 10, which facilitates the positioning, fixing and replacement of the battery.

[0033] The first main beam 111 and the second main beam 112 are spaced apart along the third direction Z, so that the same load-bearing part 11 forms a certain structural width difference in the third direction Z, thereby forming an open type 24 or a semi-closed type beam frame.

[0034] The first main beam 111 and the second main beam 112 can be profile beams or welded beams, and the cross-sectional shape of the first main beam 111 and the second main beam 112 can be C-shaped structure, I-shaped structure or rectangular structure, etc.

[0035] The reinforcing component 20 is disposed between two adjacent bearing parts 11 and connected to the bearing parts 11, which can form an overall force transmission path and improve the overall structural strength and stability of the bearing body 10.

[0036] Specifically, the reinforcing plate 21 can form a continuous connection interface with the first main beam 111, the second main beam 112, the first longitudinal beam 22, and the second longitudinal beam 23, so that the structure can achieve uniform stress distribution under bending and torsion conditions and reduce stress concentration.

[0037] The first longitudinal beam 22 can be directly connected to the first main beam 111, or it can be indirectly connected to the first main beam 111 through other components. As an example, the connection method between the first longitudinal beam 22 and the first main beam 111 can be, but is not limited to, welding, bolting, or riveting.

[0038] The second longitudinal beam 23 can be directly connected to the second main beam 112, or it can be indirectly connected to the second main beam 112 through other components. As an example, the connection method between the second longitudinal beam 23 and the second main beam 112 can be, but is not limited to, welding, bolting, or riveting.

[0039] The reinforcing plate 21 can be directly connected between the first longitudinal beam 22 and the second longitudinal beam 23, or it can be indirectly connected between the first longitudinal beam 22 and the second longitudinal beam 23 through other components. As an example, the connection method can be, but is not limited to, welding, bolting, or riveting.

[0040] Optionally, the reinforcing plate 21, the first longitudinal beam 22, and the second longitudinal beam 23 can be made of high-strength steel, aluminum alloy, or composite materials to balance load-bearing strength and lightweight requirements.

[0041] The above technical solution, by setting reinforcing members 20 between adjacent load-bearing parts 11, enables the reinforcing plate 21, the first main beam 111, the second main beam 112, the first longitudinal beam 22 and the second longitudinal beam 23 to form a closed box-shaped frame structure, forming an equivalent closed force loop, which significantly improves the bending and torsional resistance of the battery load-bearing frame.

[0042] The first longitudinal beam 22 and the second longitudinal beam 23 form an effective force transmission path for adjacent load-bearing parts 11 in the first direction X, which can reduce the local deflection and fatigue stress concentration of a single load-bearing part 11 and improve long-term durability.

[0043] The reinforcing plate 21 can resist shear force under torsional conditions, making the entire battery support frame structure stronger in shear and torsion resistance, thereby reducing the torsional deformation of the battery support frame under complex road conditions or impact conditions, and effectively improving the reliability of the battery support frame.

[0044] In some embodiments, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0045] In some embodiments, the reinforcing plate 21 may be composed of two or more segmented plates, which are respectively connected to the first longitudinal beam 22 and the second longitudinal beam 23 and spliced ​​together in the middle.

[0046] In some embodiments, the reinforcing plate 21 has an opening 24 that penetrates the reinforcing plate 21 in a third direction Z.

[0047] For example, the projection shape of the opening 24 along the third direction Z can be, but is not limited to, a circle, an ellipse, an oblong shape, a rectangle, etc.

[0048] The number of openings 24 can be one or more, where "more" refers to two or more.

[0049] The opening 24 makes it easier for the reinforcing plate 21 to undergo controllable local yielding and deformation under impact or collision loads. Together with the frame structure formed by the first longitudinal beam 22, the second longitudinal beam 23, the first main beam 111 and the second main beam 112, a certain energy absorption effect can be achieved, improving the overall reliability of the battery load-bearing frame.

[0050] The opening 24 can reduce the amount of material used in the reinforcing plate 21, achieving weight reduction while ensuring the strength of key connection positions, which is conducive to reducing the energy consumption of the whole vehicle.

[0051] The opening 24 can also form an airflow channel, which, in conjunction with the heating characteristics of the battery in the first accommodating space 12, makes it easier for heat to be discharged through convection and diffusion, thereby improving the battery thermal management efficiency.

[0052] In some embodiments, the ratio between the projected area of ​​the opening 24 along the third direction Z and the projection of the reinforcing plate 21 along the third direction Z is 0.4-0.7, which can improve the balance between structural strength, weight and heat dissipation performance.

[0053] For example, the ratio between the projected area of ​​the opening 24 along the third direction Z and the projection of the reinforcing plate 21 along the third direction Z can be 0.4, 0.5, 0.6, 0.7, etc.

[0054] In some embodiments, the reinforcing plate 21 has a plurality of weight-reducing holes 50, which helps to further reduce the overall weight of the reinforcing plate 21.

[0055] In some embodiments, a plurality of weight-reducing holes 50 are spaced apart along the outer periphery of the opening 24, which can disperse the stress path around the opening 24 in a circumferential manner, making the circumferential edge of the opening 24 more evenly stressed.

[0056] In some embodiments, the first main beam 111 protrudes from the surface of the first longitudinal beam 22 on the side facing away from the reinforcing plate 21, so as to form a second accommodating space 30 for accommodating the wire harness on the side of the first longitudinal beam 22 facing away from the reinforcing plate 21.

[0057] For example, taking the side where the reinforcing plate 21 is located as the "inner side" and the side of the first longitudinal beam 22 facing away from the reinforcing plate 21 as the "outer side", the first main beam 111 forms a protruding structure on the outer side, thereby forming a second accommodating space 30 on the outer side of the battery support frame. This second accommodating space 30 is used to accommodate wiring, which may include high-voltage wiring harnesses, low-voltage wiring harnesses, signal lines, sampling lines, grounding lines, communication lines, temperature sensor lines, cooling system control lines, etc., and may also include wiring harness protective components such as hoses, sheaths, or corrugated pipes.

[0058] The second accommodating space 30 is located outside the battery support frame, allowing operators to directly perform wiring, fixing, and maintenance from the outside. This significantly reduces spatial interference and assembly difficulty caused by threading wires within the first accommodating space 12, improving assembly efficiency and maintainability. The wiring harness, arranged within the second accommodating space 30, maintains a more stable gap with the battery, reducing the risk of collision, compression, and pulling under vibration conditions, and enhancing the durability and reliability of the wiring harness.

[0059] Figure 4 A battery support frame provided for some embodiments of this application along Figure 2 A cross-sectional structural diagram of BB in the diagram.

[0060] Continue to refer to Figure 4 In some embodiments, the reinforcing plate 21 is provided with a wiring hole 25, which penetrates the reinforcing plate 21 in the third direction Z.

[0061] For example, the projection shape of the wiring hole 25 along the third direction Z can be, but is not limited to, a circle, an ellipse, an oblong shape, a rectangle, etc.

[0062] The number of wiring holes 25 can be one or more, where "more" refers to two or more.

[0063] The wiring hole 25 provides a direct channel for the wire harness to cross the reinforcing plate 21, so that the wire harness can be laid without detouring or passing through narrow gaps. Structurally, it shortens the wiring path and reduces the number of turns, which significantly reduces the difficulty of wire harness laying and assembly time.

[0064] In some embodiments, the wiring hole 25 is located on the side of the reinforcing plate 21 near the first longitudinal beam 22.

[0065] In some embodiments, the wiring hole 25 is located on the side of the reinforcing plate 21 near the second longitudinal beam 23.

[0066] In some embodiments, the reinforcing plate 21 includes a first plate portion and a second plate portion, the plane of the first plate portion is perpendicular to the second direction Y, and the plane of the second plate portion intersects with the plane of the first plate portion.

[0067] This makes the reinforcing plate 21 form a bent plate structure, which makes the reinforcing plate 21 more easily deformable and absorb energy when subjected to external loads, thereby helping to reduce the peak value of the load transmitted to the load-bearing body 10 and reduce the risk of cracking of the load-bearing body 10.

[0068] In some embodiments, the opening 24 is provided in the first plate portion.

Figure 6 Another battery support frame provided for some embodiments of this application along Figure 5 A cross-sectional structural diagram of CC in the diagram.

[0070] Continue to refer to Figures 5 to 6 In some embodiments, the reinforcing plate 21 is provided with a first protruding rib 26, which connects the first longitudinal beam 22 and the second longitudinal beam 23.

[0071] By setting a first rib 26 on the reinforcing plate 21 to connect the first longitudinal beam 22 and the second longitudinal beam 23, the first rib 26 can guide the force flow on the surface of the reinforcing plate 21, thereby guiding and diverting the load transmission path on the reinforcing plate 21. The impact force or bending force can be dispersed and transmitted to the first longitudinal beam 22 and the second longitudinal beam 23 along a predetermined path, thereby reducing the peak stress in a certain local area, further reducing the risk of cracking, and further improving the reliability of the battery load-bearing frame.

[0072] The first rib 26 is a raised rib structure formed on the surface of the reinforcing plate 21, which can be made by stamping, rolling, hydroforming or welding of parts.

[0073] Optionally, the cross-sectional shape of the first rib 26 perpendicular to the third direction Z can be semi-circular, trapezoidal, or triangular, etc.

[0074] Optionally, the number of first ribs 26 can be one or more, where "more" refers to two or more.

[0075] In some embodiments, the first rib 26 and the reinforcing plate 21 are integrally formed, which can simplify the manufacturing process and reduce costs.

[0076] In some embodiments, the support portion 11 further includes a first crossbeam 113, which is connected between the first main beam 111 and the second main beam 112, and the reinforcing plate 21 is connected between the first crossbeams 113 of two adjacent support portions 11.

[0077] By adding a first crossbeam 113 connecting the first main beam 111 and the second main beam 112, a stable transverse frame unit is formed between the first main beam 111 and the second main beam 112, improving the structural stability of a single load-bearing part 11. Simultaneously, a reinforcing plate 21 is connected between the first crossbeams 113 of two adjacent load-bearing parts 11, so that the reinforcing plate 21 and the first crossbeam 113 together form a stable support structure, allowing the load to be distributed more evenly between adjacent load-bearing parts 11, thereby further improving the reliability of the battery load-bearing frame.

[0078] The first crossbeam 113 can be made of high-strength steel, aluminum alloy, or composite materials to balance load-bearing strength and lightweight requirements. The first crossbeam 113 can be a profile beam or a welded beam, and the cross-sectional shape of the first crossbeam 113 can be a C-shaped structure, an I-shaped structure, or a rectangular structure, etc.

[0079] The reinforcing plate 21 can be directly connected to the first crossbeam 113, or it can be indirectly connected to the first crossbeam 113 through other components. As an example, the connection method between the reinforcing plate 21 and the first crossbeam 113 can be, but is not limited to, welding, bolting, or riveting.

[0080] In some embodiments, the corner of the reinforcing plate 21 is provided with a clearance opening to facilitate the fixed connection between the first longitudinal beam 22 and the first main beam 111, and to facilitate the fixed connection between the first longitudinal beam 22 and the first cross beam 113.

[0081] In some embodiments, the load-bearing part 11 further includes a first reinforcing beam 114, which connects the first main beam 111 and the first crossbeam 113.

[0082] By adding a first reinforcing beam 114, a triangular support structure is formed between the first main beam 111 and the first cross beam 113, thereby improving the overall structural stability of the load-bearing part 11.

[0083] The first reinforcing beam 114 can be directly connected to the first main beam 111, or it can be indirectly connected to the first main beam 111 through other components. As an example, the connection method between the first reinforcing beam 114 and the first main beam 111 can be, but is not limited to, welding, bolting, or riveting.

[0084] The first reinforcing beam 114 can be directly connected to the first crossbeam 113, or it can be indirectly connected to the first crossbeam 113 through other components. As an example, the connection method between the first reinforcing beam 114 and the first crossbeam 113 can be, but is not limited to, welding, bolting, or riveting.

[0085] The first reinforcing beam 114 can be made of high-strength steel, aluminum alloy, or composite materials to balance load-bearing strength and lightweight requirements. The first reinforcing beam 114 can be a profile beam or a welded beam, and its cross-sectional shape can be a C-shaped structure, an I-shaped structure, or a rectangular structure, etc.

[0086] In some embodiments, the load-bearing portion 11 further includes a second reinforcing beam 115, which connects the second main beam 112 and the first crossbeam 113.

[0087] By adding a second reinforcing beam 115, a triangular support structure is formed between the second main beam 112 and the first crossbeam 113, thereby improving the overall structural stability of the load-bearing part 11.

[0088] The second reinforcing beam 115 can be made of high-strength steel, aluminum alloy, or composite materials to balance load-bearing strength and lightweight requirements.

[0090] In some embodiments, the load-bearing portion 11 further includes a fourth reinforcing beam, which connects the second main beam 112 and the second longitudinal beam 23.

[0091] In some embodiments, the reinforcing plate 21 is provided with a second rib, which connects the first longitudinal beam 22 and the first cross beam 113. The second rib can distribute and transfer stress to the first longitudinal beam 22 and the first cross beam 113.

[0092] In some embodiments, the reinforcing plate 21 is provided with a third rib, which connects the second longitudinal beam 23 and the first cross beam 113. The third rib can distribute and transfer stress to the second longitudinal beam 23 and the first cross beam 113.

[0093] In some embodiments, the support portion 11 further includes a second crossbeam, which is connected between the first main beam 111 and the second main beam 112. The first crossbeam 113 and the second crossbeam are spaced apart along the second direction Y, which can further improve the structural stability of the support portion 11.

[0095] Continue to refer to Figure 7 In some embodiments, the supporting body 10 further includes a side beam 13, which extends along a first direction X and connects to a plurality of supporting parts 11. The side beam 13 is located at the end of the supporting part 11 along a second direction Y. The side beam 13 includes a beam body 131 and a reinforcing member 132. The beam body 131 includes a first wall 1311, a second wall 1312, and a third wall 1313. The first wall 1311 and the second wall 1312 are arranged opposite each other along the second direction Y. The third wall 1313 is connected between the first wall 1311 and the second wall 1312 and is arranged along a third direction Z close to the first accommodating space 12. The reinforcing member 132 is connected between the first wall 1311 and the second wall 1312 and is arranged opposite to the third wall 1313 along the third direction Z. The projected area of ​​the reinforcing member 132 along the third direction Z is smaller than the projected area of ​​the third wall 1313 along the third direction Z.

[0096] The projected area of ​​the reinforcing member 132 along the third direction Z is smaller than the projected area of ​​the third wall 1313 along the third direction Z. That is, the reinforcing member 132 is smaller than the third wall 1313. It does not completely enclose the C-shaped structure into a box beam, but provides local support and deformation resistance in key areas. Specifically, the reinforcing member 132 can be set as a short span plate, reinforcing rib, bridging plate or local transverse stiffener. Its position can correspond to the easily deformable area of ​​the main beam 131. The main beam 131 is reinforced by a small volume component, which suppresses the expansion of the opening 24, buckling or warping deformation of the C-shaped beam under load.

[0097] Optionally, the reinforcing member 132 may be made of high-strength steel, aluminum alloy or composite material to balance load-bearing strength and lightweight requirements.

[0098] The reinforcing member 132 can be directly connected between the first wall 1311 and the second wall 1312, or it can be indirectly connected between the first wall 1311 and the second wall 1312 through other components. As an example, the connection method can be, but is not limited to, welding, bolting, or riveting.

[0099] The above technical solution, by setting the edge beams 13, enables multiple load-bearing parts 11 to form a continuous connection at the boundary, which can improve the overall boundary support capacity and structural continuity of the load-bearing main body 10. The beam body 131 adopts a C-shaped structure composed of the first wall 1311, the second wall 1312, and the third wall 1313, which reduces the amount of material used while meeting the load-bearing requirements, which is conducive to reducing the overall weight of the load-bearing main body 10 and achieving lightweighting.

[0100] Meanwhile, by setting up a reinforcing member 132 with a smaller projected area to locally cross-connect and constrain the first wall 1311 and the second wall 1312, the deformation on the side of the C-shaped opening 24 can be effectively suppressed, and the local strength, deformation resistance and reliability of the side beam 13 can be improved. Thus, while reducing the overall weight of the load-bearing body 10 and achieving lightweighting, the reliability of its structure can also be taken into account.

[0101] In some embodiments, the number of reinforcing members 132 is multiple, and the multiple reinforcing members 132 are spaced apart along the first direction X.

[0102] In some embodiments, in the same plane perpendicular to the second direction Y, the orthographic projection of the reinforcing member 132 at least partially overlaps with the orthographic projection of the first main beam 111. This ensures that the reinforcing member 132 is arranged to correspond to the connection position where the first main beam 111 transmits force to the side beam 13, thereby enabling targeted support for the connection area between the first main beam 111 and the beam body 131.

[0103] In some embodiments, in the same plane perpendicular to the second direction Y, the orthographic projection of the reinforcing member 132 at least partially overlaps with the orthographic projection of the second main beam 112. This ensures that the reinforcing member 132 is arranged to correspond to the connection position where the second main beam 112 transmits force to the side beam 13, thereby enabling targeted support for the connection area between the second main beam 112 and the beam body 131.

[0104] In some embodiments, the battery support frame further includes a heat insulation component, which is disposed on the outside of the support body 10 and encloses the first accommodating space 12. The reinforcing member 132 is provided with a mounting part, and the heat insulation component is fixedly connected to the mounting part.

[0105] The heat insulation component forms a covering and enclosed structure on the outside of the supporting body 10, so that the first accommodating space 12 forms a relatively independent thermal environment, thereby reducing the direct impact of external temperature changes on the battery, and playing a certain role in preventing dust, water splash and mud and sand intrusion in the first accommodating space 12.

[0106] The insulation component can be a plate or a shell, and it can be arranged along the outer contour of the supporting body 10 so that the battery is located in the closed cavity formed by the insulation component and the supporting body 10 after installation.

[0107] Alternatively, the mounting part can be a boss, mounting lug, flange, nut seat, or connecting piece with holes, etc.

[0108] The mounting part that fixes the insulation component to the reinforcing member 132 can effectively transfer the installation load to the side beam 13 and the load-bearing body 10 through the reinforcing member 132, thereby reducing the risk of loosening and deformation of the insulation component under vibration conditions.

[0109] In some embodiments, a fastener is provided on the first longitudinal beam 22, which can be used to fix the thermal insulation component.

[0110] In some embodiments, a fastener is provided on the second longitudinal beam 23, which can be used to fix the thermal insulation component.

[0111] In some embodiments, the ratio between the projected area of ​​the reinforcing member 132 along the third direction Z and the projected area of ​​the third wall 1313 along the third direction Z is 0.05-0.6, which can further improve the balance between the reliability of the supporting body 10 and its lightweight effect.

[0112] For example, the ratio between the projected area of ​​the reinforcing member 132 along the third direction Z and the projected area of ​​the third wall 1313 along the third direction Z can be 0.05, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, etc.

Figure 9 A battery support frame provided for some embodiments of this application along Figure 8 A schematic diagram of the cross-sectional structure of DD in the diagram.

[0114] Continue to refer to Figures 8 to 9 In some embodiments, the reinforcing plate 21 includes a first plate body 211 and a second plate body 212, the first plate body 211 and the second plate body 212 are arranged opposite to each other and spaced apart along the second direction Y, and an energy absorption cavity 40 is formed between the first plate body 211 and the second plate body 212.

[0115] When the battery support frame is subjected to impact, the energy-absorbing cavity 40 can absorb energy through the deformation of the first plate 211 and the second plate 212, reducing the transmission of the peak load to the supporting body 10, thereby further improving the overall structural reliability. At the same time, the double-layer plate structure can provide more stable plate support and anti-warping ability under normal working conditions, which helps to improve the overall bending performance of the battery support frame.

[0116] Figure 10 Another battery support frame provided for some embodiments of this application along Figure 8 A schematic diagram of the cross-sectional structure of DD in the diagram.

[0117] Continue to refer to Figure 10In some embodiments, the first plate 211 includes a first segment 2111, a second segment 2112, and a third segment 2113. The first segment 2111 is connected between the second segment 2112 and the third segment 2113. Both the second segment 2112 and the third segment 2113 are bent relative to the first segment 2111 along a line close to the second plate 212. The second plate 212 includes a fourth segment 2121, a fifth segment 2122, and a sixth segment 2123. The fourth segment 2121 is connected between the fifth segment 2122 and the sixth segment 2123. Both the fifth segment 2122 and the sixth segment 2123 are bent relative to the fourth segment 2121 along a line close to the first plate 211. The first segment 2111 and the fourth segment 2121 are arranged opposite each other along a second direction Y, the second segment 2112 and the fifth segment 2122 are arranged opposite each other along a second direction Y, and the third segment 2113 and the sixth segment 2123 are arranged opposite each other along a second direction Y.

[0118] By setting the first plate 211 and the second plate 212 as bent plate structures, more controllable and stable progressive deformation energy absorption can be formed under impact load, so that the load is more evenly distributed to the first longitudinal beam 22 and the second longitudinal beam 23, reducing the risk of cracking.

[0119] In some embodiments, the battery support frame further includes a base plate connected to the outside of the bottom support portion 11.
