[0003] This application relates to the field of new energy vehicle technology, and more specifically, to a bracket, a bracket assembly, and a vehicle. Background Technology

[0004] New energy vehicles have become an important part of the sustainable development of the vehicle industry due to their energy-saving and environmental protection advantages. With the development of new energy vehicles, people's requirements for the driving range of new energy vehicles are also increasing. In order to meet the needs of new energy vehicles to replenish power loss in a timely manner during driving, the solution of battery swapping to replenish power loss in a timely manner has emerged.

[0005] For new energy vehicles, improving the degree of lightweighting is an urgent technical problem to be solved. Summary of the Invention

[0006] This application provides a bracket, a bracket assembly, and a vehicle. The technical solution provided by this application can improve the degree of vehicle lightweighting.

[0007] This application is achieved through the following technical solution:

[0008] In a first aspect, this application provides a bracket for mounting on a vehicle frame, the bracket including a mounting beam. The mounting beam is provided with a plurality of mounting portions, which are spaced apart along the length direction of the mounting beam, and the plurality of mounting portions are used for detachably connecting a battery. A cavity is formed inside the mounting beam, extending along the length direction of the mounting beam.

[0009] In the above scheme, the bracket is used to mount on the vehicle frame, and the mounting parts on the mounting beam are used to detachably connect to the battery. By arranging multiple mounting parts at intervals along the length of the mounting beam, it is possible to achieve distributed battery swapping (i.e., on-demand battery swapping; for example, when the required range is short, a smaller number of batteries can be installed on the corresponding number of mounting parts in multiple sets; when the required range is long, a larger number of batteries can be installed on the corresponding number of mounting parts in multiple sets) and / or increase the locking points between the mounting beam and the battery to improve locking strength. Furthermore, by setting a cavity inside the mounting beam, on the one hand, the bracket can be made lighter, thereby improving the overall vehicle lightweighting; on the other hand, because the extension direction of the cavity is consistent with the arrangement direction of the multiple mounting parts, the impact of the cavity on the bracket's stiffness and strength can be effectively reduced. Compared to schemes where the cavity is arranged along an inclined or perpendicular direction to the length of the mounting beam, this reduces the risk of the bracket bending or even breaking along the mounting part due to impact, resulting in higher reliability of the bracket under conditions of high lightweighting.

[0010] According to some embodiments of this application, the mounting portion includes a mounting hole formed on the mounting beam; the mounting hole extends through the mounting beam along a first direction, the first direction being perpendicular to the length direction of the mounting beam.

[0011] In the above solution, on the one hand, the mounting part has a simple structure and is easy to manufacture; on the other hand, because the mounting part has a simple structure, the connection between the battery and the mounting part is also simple, which can effectively improve the battery swapping efficiency; furthermore, the extension direction of the cavity is perpendicular to the through direction of the mounting hole, which can effectively reduce the impact of the cavity on the rigidity and strength of the bracket, so that the bracket has high structural strength to stably mount the battery and improve the driving reliability of the vehicle.

[0012] According to some embodiments of this application, the mounting part further includes a mounting sleeve, at least a portion of which is disposed within the mounting hole.

[0013] In the above solution, by setting a mounting sleeve inside the mounting hole, the structural strength of the mounting part can be improved, so that the battery can be stably connected to the bracket, reducing the risk of battery falling off and improving the driving reliability of the vehicle.

[0014] According to some embodiments of this application, along a first direction, the mounting beam has opposing first and second end walls, and the mounting sleeve is connected to the first and second end walls.

[0015] In the above solution, by setting the mounting sleeve to connect with the first end wall and the second end wall, the mounting sleeve and the mounting beam are integrated as a whole. This can effectively improve the problem that the support structure strength may be reduced due to the cavity, improve the rigidity and strength of the mounting part, enhance the deformation resistance of the support when mounting the battery, reduce the risk of battery falling off, and thus improve the driving reliability of the vehicle.

[0016] According to some embodiments of this application, the outer contour of the cross-section of the mounting beam is rectangular.

[0017] In the above scheme, by setting the outer contour of the cross-section of the mounting beam to a rectangle, the mounting beam has good strength and rigidity after the cavity is set, thereby improving the deformation resistance of the bracket when the battery is mounted.

[0018] According to some embodiments of this application, a support member is provided inside the cavity, and the support member is connected to the hanging beam.

[0019] In the above solution, by setting up support components inside the cavity, the strength and rigidity of the mounting beam can be effectively improved, the deformation resistance of the bracket can be enhanced, and thus the driving reliability of the vehicle can be improved.

[0020] According to some embodiments of this application, the support member and the mounting beam are integrally formed.

[0021] In the above solution, the support component and the mounting beam are integrally formed, which enables the bracket to have high strength and rigidity, improves the bracket's resistance to deformation when the battery is mounted, reduces the risk of the battery falling off, and thus improves the vehicle's driving reliability.

[0022] According to some embodiments of this application, the support and the mounting beam are formed by bending a single plate.

[0023] In the above scheme, the support components and the mounting beam are formed by bending a single plate, which makes the bracket more efficient and less expensive to manufacture.

[0024] According to some embodiments of this application, the support divides the cavity into multiple sub-cavities, which extend along the length of the mounting beam.

[0025] In the above solution, the cavity is divided into multiple sub-cavities by the support components. Each sub-cavity is independent of the others. While improving the lightweighting of the bracket, it can effectively improve the strength and rigidity of the mounting beam, enhance the bracket's resistance to deformation, reduce the risk of battery detachment, and thus improve the vehicle's driving reliability.

[0026] According to some embodiments of this application, the plurality of sub-cavities include a first sub-cavity and a second sub-cavity. The mounting beam includes a first wall, a second wall, a third wall, a fourth wall, a fifth wall, and a sixth wall. Along a second direction, both ends of the first wall are connected to one end of the second wall and one end of the third wall, respectively; along a first direction, the fourth wall is spaced apart from the first wall, and one end of the fourth wall is connected to the other end of the second wall; along a first direction, the fifth wall is spaced apart from the first wall, and one end of the fifth wall is connected to the other end of the third wall; along a first direction, one end of the sixth wall is connected to the other end of the fourth wall, and the other end of the sixth wall is connected to the first wall. The first wall, the second wall, the fourth wall, and the sixth wall together form the first sub-cavity; the other end of the fifth wall is connected to the sixth wall, and the first wall, the third wall, the fifth wall, and the sixth wall together form the second sub-cavity. The first direction, the second direction, and the length direction of the mounting beam are all perpendicular to each other.

[0027] In the above scheme, the mounting beam structure is simple and easy to manufacture. The support component may include a sixth wall. By setting the sixth wall, which connects the fourth wall and the first wall that are opposite to each other on the mounting beam, the strength and rigidity of the mounting beam can be effectively improved, the risk of battery detachment can be reduced, the deformation resistance of the bracket can be improved, and thus the driving reliability of the vehicle can be improved.

[0028] According to some embodiments of this application, the end of the sixth wall away from the fourth wall is provided with a first bend, the first bend extending along a second direction and connected to the first wall.

[0029] In the above solution, by setting the first bending part, the connection area between the sixth wall and the first wall can be increased, the support capacity of the sixth wall can be improved, the strength and rigidity of the mounting beam can be effectively improved, the deformation resistance of the bracket can be improved, the risk of battery detachment can be reduced, and thus the driving reliability of the vehicle can be improved.

[0030] According to some embodiments of this application, the first bend extends from the end of the sixth wall toward the third wall.

[0031] The above solution, by setting the first bending part to extend towards the third wall, enables the bracket to evenly bear the impact, improves the bracket's resistance to deformation, reduces the risk of battery detachment, and thus improves the vehicle's driving reliability.

[0032] According to some embodiments of this application, the end of the fifth wall away from the third wall is provided with a second bend, the second bend extending along a first direction and connected to the sixth wall.

[0033] In the above scheme, by setting the second bending part, the connection area between the fifth wall and the sixth wall can be increased, the connection reliability between the fifth wall and the sixth wall can be improved, and the geometry of the cross-section of the hanging beam has good load-bearing capacity. Under the condition of reducing the structural mass, the bracket has good resistance to deformation.

[0034] According to some embodiments of this application, the bracket further includes a connecting portion connected to the mounting beam, the connecting portion being used to connect to the longitudinal beam of the vehicle frame.

[0035] In the above solution, by setting up a connecting part, the mounting beam can be effectively connected to the longitudinal beam of the frame, so that the mounting beam can effectively support the battery through the mounting part, reducing the risk of battery detachment and improving the driving reliability of the vehicle.

[0036] According to some embodiments of this application, the mounting beam is provided with two connecting parts, which are spaced apart. The two connecting parts and the mounting beam together form an upward-opening groove for the vehicle frame to pass through.

[0037] In the above solution, by setting two connecting parts, on the one hand, it can form a groove to avoid the longitudinal beams of the frame; on the other hand, it can connect the connecting parts to the outer side of the corresponding longitudinal beams, that is, the two longitudinal beams of the frame are respectively connected by the corresponding connecting parts, so that the mounting unit and the frame have a stable connection relationship, reducing the risk of battery detachment and improving the reliability of vehicle operation; furthermore, since there are two connecting parts, and the two connecting parts are set laterally along the frame, the mounting beam can be set with more mounting parts to mount larger batteries or more batteries, thereby effectively improving the vehicle's range.

[0038] According to some embodiments of this application, the bracket also includes a rib plate located on the side of the connector opposite to the groove, and the rib plate connects the mounting beam and the connector.

[0039] In the above solution, by setting ribs on the outside of the frame, the space between the connecting part and the mounting beam can be made reasonable, and the structural strength of the connecting part and the mounting beam can be improved, reducing the risk of battery detachment and improving the driving reliability of the vehicle.

[0040] According to some embodiments of this application, a bent portion is provided at one end of the rib plate near the mounting beam, and the rib plate is connected to the mounting beam through the bent portion.

[0041] In the above scheme, by setting a bend at the end of the rib near the load beam, the connection area between the rib and the load beam can be increased, thereby improving the connection reliability between the rib and the load beam.

[0042] According to some embodiments of this application, a notch is formed at one end of the rib plate near the mounting beam, and the notch is provided corresponding to the mounting part.

[0043] In the above solution, by setting a notch at one end of the rib plate near the mounting beam, space above the mounting part can be left free, reducing the risk of the battery being interfered with by the rib plate when mounted on the mounting part.

[0044] According to some embodiments of this application, the connecting part is a flange provided on the rib plate, and the rib plate and the connecting part are arranged perpendicular to each other.

[0045] In the above scheme, the connecting part can be a flange set on the rib plate. For example, the connecting part and the rib plate are integrally formed, which can make the connecting part and the rib plate have high structural strength, effectively provide structural strength for the mounting beam, thereby effectively supporting the battery and reducing the risk of battery falling off.

[0046] According to some embodiments of this application, the rib includes a first rib and a second rib stacked together, and the connecting portion includes a first sub-connecting portion and a second sub-connecting portion, wherein the first sub-connecting portion is a flange disposed on the first rib and the second sub-connecting portion is a flange disposed on the second rib.

[0047] In the above scheme, the rib can be a double-layer plate structure. Since the rib is a double-layer plate structure, the rib can form two flanges facing opposite directions, that is, form the first sub-connection part and the second sub-connection part, so that there is a large connection area between the rib and the longitudinal beam, improving the connection reliability between the rib and the longitudinal beam, thereby improving the structural strength of the mounting beam, enabling the mounting beam to effectively support the battery and reducing the risk of battery falling off.

[0048] According to some embodiments of this application, the bracket includes a plurality of mounting beams, which are spaced apart, and a receiving space for accommodating at least a portion of the battery is formed between two adjacent mounting beams.

[0049] In the above solution, the bracket includes multiple mounting beams, so that at least a portion of the receiving space for accommodating the battery can be formed between two adjacent mounting beams, so that the battery can be installed in the corresponding receiving space in an orderly manner, thereby improving the battery swapping efficiency of the vehicle.

[0050] Secondly, some embodiments of this application also provide a bracket assembly, including a vehicle frame and the bracket provided in the first aspect. The bracket is mounted on the longitudinal beam of the vehicle frame.

[0051] In the above solution, by installing brackets on the longitudinal beams of the chassis, the chassis can achieve a high degree of weight reduction while still enabling battery swapping operations.

[0052] According to some embodiments of this application, the longitudinal beam includes a web, an upper flange, and a lower flange, with the web connecting the upper flange and the lower flange. The support also includes a connecting portion connected to the web.

[0053] In the above solution, the bracket is connected to the web of the longitudinal beam through the connecting part, which enables the bracket to be effectively installed on the longitudinal beam, reduces the risk of the bracket falling off the longitudinal beam, and improves the reliability of vehicle operation.

[0054] According to some embodiments of this application, the mounting beam is connected to the lower flange.

[0055] In the above solution, the bracket is connected to the web of the longitudinal beam through the connecting part and to the lower flange of the longitudinal beam through the mounting beam. This allows the bracket to be firmly installed on the longitudinal beam, reducing the risk of the bracket falling off the longitudinal beam and improving the reliability of vehicle operation.

[0056] According to some embodiments of this application, the support assembly further includes a reinforcing member that is connected to the longitudinal beam and the connecting portion.

[0057] In the above solution, by setting reinforcement components, the connection stability between the bracket and the longitudinal beam can be improved on the one hand, and the structural strength of the connection part can be effectively improved on the other hand, thereby improving the structural stability of the bracket, reducing the risk of battery detachment, and improving the driving stability of the vehicle.

[0058] According to some embodiments of this application, the reinforcing member includes a first part and a second part that are interconnected. The first part is located on the side of the connecting portion away from the web plate. The first part, the connecting portion, and the web plate are interconnected. The second part is connected to the upper wing plate.

[0059] In the above solution, the bracket is connected to the web of the longitudinal beam through the connecting part, and to the upper flange of the longitudinal beam through the second part of the reinforcing member. This allows the bracket to be firmly installed on the longitudinal beam, reducing the risk of the bracket falling off the longitudinal beam and improving the reliability of vehicle operation.

[0060] According to some embodiments of this application, the first part is provided with a first through hole, the connecting part is provided with a second through hole, the web is provided with a third through hole, and the bracket assembly further includes a first fastener, which passes through the first through hole, the second through hole and the third through hole to fix the first part and the connecting part to the web.

[0061] In the above solution, by providing a first through hole in the first part of the reinforcing member, a second through hole in the connecting part, and a third through hole in the web of the longitudinal beam, the first fastener can lock the reinforcing member, the connecting part, and the longitudinal beam together as one unit, so that the bracket is firmly installed on the longitudinal beam, reducing the risk of the bracket falling off the longitudinal beam and improving the reliability of vehicle operation.

[0062] According to some embodiments of this application, the second part is provided with a fourth through hole, the upper wing plate is provided with a fifth through hole, and the bracket assembly further includes a second fastener, which passes through the fourth through hole and the fifth through hole to fix the second part to the upper wing plate.

[0063] In the above solution, by setting a fourth through hole in the second part of the reinforcing member and a fifth through hole in the upper flange of the longitudinal beam, the second fastener can lock the reinforcing member and the longitudinal beam together, so that the bracket is firmly installed on the longitudinal beam, reducing the risk of the bracket falling off the longitudinal beam and improving the reliability of vehicle operation.

[0064] Thirdly, some embodiments of this application also provide a vehicle, including:

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0083] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0084] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.

[0089] Currently, new energy vehicles often use battery swapping to replenish the power lost during driving.

[0090] For new energy vehicles, lightweighting affects the manufacturing cost and driving range, so how to achieve lightweighting is an urgent technical problem to be solved.

[0091] New energy vehicles with battery swapping capabilities often have a frame equipped with a battery swapping bracket. The bracket's mounting beam has a mounting section for detachable connection to the battery. The mounting section includes mounting holes on the mounting beam, which are typically through holes penetrating two opposite walls of the beam. Currently, to reduce the impact of mounting holes on the strength and rigidity of the mounting beam, it is often a solid structure, resulting in greater weight and affecting the vehicle's lightweight design.

[0092] In view of this, to improve the lightweighting of vehicles, some embodiments of this application provide a bracket for mounting to a vehicle frame, the bracket including a mounting beam. The mounting beam is provided with multiple mounting parts, which are spaced apart along the length direction y of the mounting beam, and the multiple mounting parts are used for detachably connecting to a battery. A cavity is formed inside the mounting beam, extending along the length direction of the mounting beam.

[0093] In the above scheme, the bracket is used to install on the vehicle frame, and the mounting part on the mounting beam is used to detachably connect to the battery. By arranging multiple mounting parts at intervals along the length direction y of the mounting beam, it is possible to achieve subcontracted battery swapping (i.e., on-demand battery swapping; for example, when the required range is short, a smaller number of batteries can be installed on the corresponding number of mounting parts in multiple sets of mounting parts; when the required range is long, a larger number of batteries can be installed on the corresponding number of mounting parts in multiple sets of mounting parts) and / or increase the number of locking points between the mounting beam and the battery to improve the locking strength. By incorporating a cavity within the mounting beam, the bracket can be made lighter, thereby improving the overall lightweighting of the vehicle. Furthermore, since the cavity extends in the same direction as the arrangement of multiple mounting sections, the impact of the cavity on the bracket's stiffness and strength can be effectively reduced. Compared to designs where the cavity is inclined or perpendicular to the length of the mounting beam, this reduces the risk of the bracket bending or even breaking along the mounting section due to impact, resulting in higher reliability of the bracket even with a high degree of lightweighting.

[0094] The brackets disclosed in this application can be, but are not limited to, installed on the frames of passenger vehicles, commercial vehicles, and other types of frames. The vehicles disclosed in this application can be, but are not limited to, used in passenger vehicles, commercial vehicles, and other types of vehicles.

The length direction y of the mounting beam can be the direction with the larger dimension of the mounting beam 11. Please refer to [link / reference]. Figure 2 The length direction y of the mounting beam can be perpendicular to the longitudinal direction (length direction of the longitudinal beam 51). In some embodiments, such as Figure 2 A portion of the mounting beam 11 may be located between a pair of longitudinal beams 51 of the frame 50, and a portion of the mounting beam 11 may be located on both sides of the frame 50 along the transverse direction of the frame 50. In other embodiments, the mounting beam 11 may be located on the outer side of the frame 50. In still other embodiments, the mounting beam 11 may be located between a pair of longitudinal beams 51 of the frame 50.

[0105] In some embodiments, the bracket 10 may include a plurality of mounting beams 11, which may be spaced apart, for example, along a direction perpendicular to the length direction y of the mounting beams. In some embodiments, the plurality of mounting beams 11 may be interconnected by connecting members, for example, adjacent two mounting beams 11 may be connected by a connecting rod.

[0106] The mounting part 110 is used for detachable connection with the battery 200. When the bracket 10 is applied to a vehicle, the detachable connection between the mounting part 110 and the battery 200 enables battery swapping of the vehicle.

[0107] There are multiple mounting parts 110. On a mounting beam 11, multiple mounting parts 110 are arranged at intervals along the length direction y of the mounting beam.

[0108] In some embodiments, multiple mounting portions 110 on the mounting beam 11 can be used to connect the same battery 200. In some embodiments, multiple mounting portions 110 on the mounting beam 11 can be used to connect different batteries 200; for example, some mounting portions 110 on the mounting beam 11 are used to connect the same battery 200, while others are used to connect another battery 200. In some embodiments, one mounting beam 11 can mount one or more batteries 200. In some embodiments, multiple mounting beams 11 can jointly mount one or more batteries 200.

[0109] In some embodiments, the mounting portion 110 includes, but is not limited to, mounting holes, mounting threads, and other structures that enable a detachable connection with the battery 200.

[0110] The phrase "the interior of the mounting beam 11 has a cavity 111" can be understood as the presence of a cavity 111 inside the mounting beam 11, which makes the mounting beam 11 lightweight. In some embodiments, the cavity 111 may refer to a hollow portion inside the mounting beam 11, which may or may not penetrate the wall of the mounting beam 11. For example, in some embodiments, the cavity 111 penetrates both ends of the mounting beam 11 along its length direction y. In other embodiments, the cavity 111 is a chamber structure located inside the mounting beam 11, which is not connected to the outside.

[0111] "The cavity 111 extends along the length direction y of the mounting beam" can be understood as the direction of the maximum size of the cavity 111 being the length direction y of the mounting beam, which can also be understood as the cavity 111 extending along the arrangement direction of the multiple mounting parts 110.

[0112] In the above scheme, the bracket 10 is used to be mounted on the vehicle frame 50, and the mounting part 110 on the mounting beam 11 is used to be detachably connected to the battery 200. By arranging multiple mounting parts 110 at intervals along the length direction y of the mounting beam, it is possible to achieve battery swapping in a subcontracted manner (that is, battery swapping on demand; for example, when the required range is short, a smaller number of batteries 200 can be installed on the corresponding number of mounting parts 110 in multiple sets of mounting parts 110; when the required range is long, a larger number of batteries 200 can be installed on the corresponding number of mounting parts 110 in multiple sets of mounting parts 110) and / or increase the locking points between the mounting beam 11 and the battery 200 to improve the locking strength. By setting a cavity 111 inside the mounting beam 11, the bracket 10 can be made lighter, thereby improving the degree of vehicle lightweighting. On the other hand, since the cavity 111 is set to extend along the length direction y of the mounting beam, it can effectively reduce the impact on the stiffness and strength of the bracket 10. Compared with the scheme where the cavity 111 is set along the inclined or perpendicular length direction y of the mounting beam, it can reduce the risk of the bracket 10 bending or even breaking along the mounting part 110 due to impact, so that the bracket 10 has high reliability under the condition of high lightweighting.

[0113] According to some embodiments of this application, please refer to Figure 4 , Figure 4 for Figure 2 Enlarged view at point A. The mounting part 110 includes a mounting hole 1100 formed on the mounting beam 11. The mounting hole 1100 penetrates the mounting beam 11 along a first direction z, which is perpendicular to the length direction y of the mounting beam.

[0114] The mounting hole 1100 can be a through-hole structure extending through the mounting beam 11 along a first direction z. The first direction z is perpendicular to the length direction of the mounting beam 11. In some embodiments, when the bracket 10 is applied to a vehicle, the first direction z can be the direction of gravity. In some embodiments, the battery 200 has a mounting member that can pass through the mounting hole 1100 and be mounted on the mounting beam 11.

[0115] In some embodiments, the mounting hole 1100 penetrates the mounting beam 11 along the first direction z, and the cavity 111 can penetrate the mounting beam 11 along the length direction y of the mounting beam. In some embodiments, the mounting hole 1100 and the cavity 111 can communicate with each other inside the mounting beam 11. In some embodiments, when the bracket 10 is applied to a vehicle, since both the mounting hole 1100 and the cavity 111 penetrate the mounting beam 11, and the mounting hole 1100 and the cavity 111 are interconnected inside the mounting beam 11, water flowing into the bracket 10 from the outside can be quickly drained into the mounting beam 11.

[0116] In the above solution, on the one hand, the mounting part 110 has a simple structure and is easy to manufacture; on the other hand, because the mounting part 110 has a simple structure, the connection method between the battery 200 and the mounting part 110 is also simple, which can effectively improve the battery swapping efficiency; furthermore, the extension direction of the cavity 111 is perpendicular to the through direction of the mounting hole 1100, which can effectively reduce the influence of the cavity 111 on the stiffness and strength of the bracket 10, so that the bracket 10 has high structural strength to stably mount the battery 200 and improve the driving reliability of the vehicle.

[0117] According to some embodiments of this application, please refer to Figure 5 , Figure 5 This is a schematic diagram of the mounting hole 1100 and mounting sleeve 1101 in some embodiments of this application.

[0118] The mounting part 110 also includes a mounting sleeve 1101, at least a portion of which is disposed within the mounting hole 1100.

[0119] In some embodiments, the mounting sleeve 1101 may be disposed within the mounting hole 1100. The mounting sleeve 1101 may be disposed within the mounting hole 1100 by means of bonding, welding, threaded connection, or other methods. In some embodiments, the material of the mounting sleeve 1101 may be the same as or different from the material of the mounting beam 11. In some embodiments, the material of the mounting sleeve 1101 may be aluminum alloy, steel, or reinforced plastic, etc.

[0120] In the above solution, by setting a mounting sleeve 1101 inside the mounting hole 1100, the structural strength of the mounting part 110 can be improved, so that the battery 200 can be stably connected to the bracket 10, reducing the risk of the battery 200 falling off and improving the driving reliability of the vehicle.

[0121] According to some embodiments of this application, see Figure 5 Along the first direction z, the mounting beam 11 has a first end wall 112 and a second end wall 113 opposite to each other, the mounting sleeve 1101 extends beyond the first end wall 112 and the second end wall 113, and the mounting sleeve 1101 is connected to the first end wall 112 and the second end wall 113.

[0122] The first end wall 112 and the second end wall 113 are two wall portions of the mounting beam 11 that are opposite each other in the first direction z. In some embodiments, the first direction z can be the direction of gravity, the first end wall 112 can be the top wall of the mounting beam 11, and the second end wall 113 can be the bottom wall of the mounting beam 11.

[0123] "The connection between the mounting sleeve 1101 and the first end wall 112 and the second end wall 113" can be understood as the two ends of the mounting sleeve 1101 in the first direction z being able to connect to the first end wall 112 and the second end wall 113. The connection relationships between the mounting sleeve 1101 and the first end wall 112, and between the mounting sleeve 1101 and the second end wall 113, include but are not limited to welding, bonding, screwing, riveting, etc.

[0124] In some embodiments, in the first direction z, the size of the mounting beam 11 may exceed the size of the mounting beam 11, such that either end of the mounting beam 11 can extend beyond the first end wall 112 and the second end wall 113. For example, in the first direction z, both ends of the mounting beam 11 extend beyond the first end wall 112 and the second end wall 113, with the portion of the mounting beam 11 extending beyond the first end wall 112 connected to the first end wall 112, and the portion of the mounting beam 11 extending beyond the second end wall 113 connected to the second end wall 113.

[0125] For example, please see Figure 5 The portion of the mounting beam 11 extending beyond the first end wall 112 may have a flange, which can be connected to the outer surface of the first end wall 112. The connection between the flange and the first end wall 112 includes, but is not limited to, overlapping, welding, bonding, riveting, or threaded connections. The other end of the mounting beam 11 can be connected to the second end wall 113. The mounting beam 11 can be connected to the inner or outer surface of the second end wall 113. The connection between the mounting beam 11 and the second end wall 113 includes, but is not limited to, overlapping, welding, bonding, riveting, or threaded connections. When the bracket 10 is applied to a vehicle, due to the cavity 111, the second end wall 113 and the first end wall 112 are spaced apart. When the mounting beam 11 carries the battery 200, the weight of the battery 200 is distributed to the first end wall 112 and the second end wall 113 through the mounting sleeve 1101, improving the deformation resistance of the mounting beam 11.

[0126] In some embodiments, the portion of the mounting beam 11 extending beyond the second end wall 113 may be formed with a flange, which may be connected to the outer surface of the second end wall 113. The connection relationship between the flange and the second end wall 113 includes, but is not limited to, overlapping, welding, bonding, riveting, or threaded connection.

[0127] In the above solution, by setting the mounting sleeve 1101 to be connected to the first end wall 112 and the second end wall 113, the mounting sleeve 1101 and the mounting beam 11 are integrated as a whole. This can effectively improve the problem that the structural strength of the bracket 10 may be reduced due to the cavity 111, improve the rigidity and strength of the mounting part 110, enhance the deformation resistance of the bracket 10 when mounting the battery 200, reduce the risk of the battery 200 falling off, and thus improve the driving reliability of the vehicle.

[0128] According to some embodiments of this application, please refer to Figure 2 The outer contour of the cross-section of the suspended beam 11 is rectangular.

[0129] The cross-section of the mounting beam 11 can be understood as a plane obtained by cutting off the mounting beam 11 with a plane perpendicular to the length direction y of the mounting beam. The outer contour of the cross-section of the mounting beam 11 being rectangular can be understood as the outer contour of the cross-section of the mounting beam 11 being rectangular or similar to a rectangle.

[0130] In some embodiments, the cross-section of the mounting beam 11 is hollow, and the hollow is formed by the cavity 111.

[0131] In the above scheme, by setting the outer contour of the cross-section of the mounting beam 11 to a rectangle, the mounting beam 11 has good strength and rigidity after the cavity 111 is provided, thereby improving the deformation resistance of the bracket 10 when the battery 200 is mounted.

[0132] In other embodiments, the cross-section of the mounting beam 11 can be triangular, pentagonal, or other shapes.

[0133] According to other embodiments of this application, please refer to Figure 6 , Figure 6 This is a schematic diagram of the cross-section of the mounting beam 11 in some other embodiments of this application.

[0134] A support member 1110 is provided inside the cavity 111, and the support member 1110 is connected to the hanging beam 11.

[0135] The support member 1110 is a component disposed within the cavity 111, and both ends of the support member 1110 can be connected to the inner wall of the mounting beam 11. In some embodiments, the support member 1110 can be a rod-shaped component or a similar rod-shaped component, and its opposite ends can be connected to different inner walls of the mounting beam 11 (for example, the opposite ends of the support member 1110 can be connected to the opposite inner walls of the mounting beam 11).

[0136] In some embodiments, the material of the mounting sleeve 1101 may be the same as or different from the material of the mounting beam 11. In some embodiments, the material of the mounting sleeve 1101 may be aluminum alloy, steel, or reinforced plastic, etc.

[0137] In some embodiments, the support member 1110 may be a component of the mounting beam 11, for example, integrally formed with the mounting beam 11. In other embodiments, the support member 1110 is not a component of the mounting beam 11, and the support member 1110 is placed into the cavity 111 after the mounting beam 11 is provided with the cavity 111.

[0138] In some embodiments, the thickness direction of the support member 1110 may be perpendicular to the first direction z.

[0139] In the above solution, by setting a support member 1110 in the cavity 111, the strength and rigidity of the mounting beam 11 can be effectively improved, the deformation resistance of the bracket 10 can be improved, and thus the driving reliability of the vehicle can be improved.

[0140] According to some embodiments of this application, the support member 1110 is integrally formed with the mounting beam 11.

[0141] In some embodiments, the support member 1110 and the mounting beam 11 can be integrally formed by casting or roll forming processes.

[0142] Roll forming is a process that relies on the plastic movement properties of materials to form various complex parts using the principle of rolling extrusion. For an example, please refer to... Figure 6 The support component 1110 and the mounting beam 11 can be manufactured by roll forming of sheet metal parts.

[0143] In the above scheme, the support component 1110 and the mounting beam 11 are integrally formed, which enables the bracket 10 to have high strength and rigidity, improves the deformation resistance of the bracket 10 when mounting the battery 200, reduces the risk of the battery 200 falling off, and thus improves the driving reliability of the vehicle.

[0144] According to some embodiments of this application, the support member 1110 and the mounting beam 11 are formed by bending a single plate.

[0145] In some embodiments, the support member 1110 and the mounting beam 11 can be formed from a single sheet by a roll forming process. In other embodiments, the support member 1110 and the mounting beam 11 can be formed from a single sheet by a bending process.

[0146] The use of roll forming technology to manufacture the mounting beam 11 and the support component 1110 has the following advantages: the shape of the cross-section can be reasonably designed to improve the load-bearing capacity of the mounting beam 11 and make the mounting beam 11 lightweight; high-strength materials can be used to further reduce the weight of the mounting beam 11 while meeting the load-bearing requirements; and the manufacturing cost is low.

[0147] In the above scheme, the support 1110 and the mounting beam 11 are formed by bending a single plate, so that the bracket 10 has high manufacturing efficiency and low manufacturing cost.

[0148] According to some embodiments of this application, the support member 1110 divides the cavity 111 into a plurality of sub-cavities 111, which extend along the length direction y of the mounting beam.

[0149] The cavity 111 extends along the length direction y of the mounting beam. In some embodiments, the support member 1110 divides the cavity 111 into a plurality of sub-cavities 111 in a direction perpendicular to the length direction y of the mounting beam, such that the sub-cavities 111 extend along the length direction y of the mounting beam.

[0150] The length direction y perpendicular to the mounting beam can be a first direction z. The length direction y perpendicular to the mounting beam can also be a second direction x, which can be perpendicular to the first direction z. In some embodiments, when the support member 1110 divides the cavity 111 into multiple sub-cavities 111 along the first direction z, the mounting hole 1100 can penetrate the support member 1110. In some embodiments, when the support member 1110 divides the cavity 111 into multiple sub-cavities 111 along the first direction z, the mounting hole 1100 may not penetrate the support member 1110.

[0151] In some embodiments, when the mounting hole 1100 penetrates the support member 1110, the mounting sleeve 1101 can be connected to the support member 1110. The connection relationship between the mounting sleeve 1101 and the support member 1110 includes, but is not limited to, welding, bonding, threaded connection, riveting, etc.

[0152] In the above solution, the cavity 111 is divided into multiple sub-cavities 111 by the support member 1110. Each sub-cavity 111 is independent of each other. While improving the lightweight of the bracket 10, the strength and rigidity of the mounting beam 11 can be effectively improved, the deformation resistance of the bracket 10 can be improved, the risk of the battery 200 falling off can be reduced, and thus the driving reliability of the vehicle can be improved.

[0153] According to some embodiments of this application, please refer to Figure 6 The multiple sub-cavities 111 include a first sub-cavity 1111 and a second sub-cavity 1112. The mounting beam 11 includes a first wall 21, a second wall 22, a third wall 23, a fourth wall 24, a fifth wall 25, and a sixth wall 26. Along the second direction x, the two ends of the first wall 21 are connected to one end of the second wall 22 and one end of the third wall 23, respectively; along the first direction z, the fourth wall 24 is arranged at intervals relative to the first wall 21, and one end of the fourth wall 24 is connected to the other end of the second wall 22; along the first direction z, the fifth wall 25 is arranged at intervals relative to the first wall 21, and one end of the fifth wall 25 is connected to the other end of the third wall 23; along the first direction z, one end of the sixth wall 26 is connected to the other end of the fourth wall 24, and the other end of the sixth wall 26 is connected to the first wall 21. The first wall 21, the second wall 22, the fourth wall 24, and the sixth wall 26 together form the first sub-cavity 1111; the other end of the fifth wall 25 is connected to the sixth wall 26. The first wall 21, the third wall 23, the fifth wall 25, and the sixth wall 26 together form the second sub-cavity 1112. The first direction z, the second direction x, and the length direction y of the suspended beam are all perpendicular to each other.

[0154] In some embodiments, the mounting portion 110 can be a mounting hole 1100, which can penetrate the mounting beam 11 along a first direction z. The second direction x can be perpendicular to the first direction z, or it can be perpendicular to the length direction y of the mounting beam.

[0155] In some embodiments, the mounting beam 11 and the support member 1110 can be formed by bending a plate-like structure. See also Figure 6 The mounting beam 11 includes a first wall 21, a second wall 22, a third wall 23, a fourth wall 24, a fifth wall 25, and a sixth wall 26. The two ends of the first wall 21 in the second direction x can be bent in the same direction along the first direction z to form the second wall 22 and the third wall 23, respectively. The second wall 22 is bent in the second direction x toward the third wall 23 to form the fourth wall 24. The fourth wall 24 is bent in the first direction z toward the first wall 21 to form the sixth wall 26. The third wall 23 is bent in the second direction x toward the second wall 22 to form the fifth wall 25. The end of the fifth wall 25 away from the third wall 23 can be connected to the sixth wall 26.

[0156] The end of the sixth wall 26 away from the fourth wall 24 can be connected to the first wall 21 to provide support. The sixth wall 26 can be at least a part of the structure of the support member 1110, or it can be understood that the support member 1110 includes the sixth wall 26.

[0157] In some embodiments, the mounting hole 1100 may penetrate the first wall 21 and the fifth wall 25, or the mounting hole 1100 may penetrate the first wall 21 and the fourth wall 24.

[0158] Alternatively, in some other embodiments, unlike the directions described above, the descriptions of the first wall 21, second wall 22, third wall 23, fourth wall 24, fifth wall 25, and sixth wall 26 regarding the first direction z and the second direction x can be interchanged. For example, along the first direction z, both ends of the first wall 21 are connected to one end of the second wall 22 and one end of the third wall 23, respectively. That is, both ends of the first wall 21 in the first direction z can be bent in the same direction z to form the second wall 22 and the third wall 23, respectively. In these other embodiments, the mounting hole 1100 can penetrate the third wall 23, the sixth wall 26, and the second wall 22.

[0159] In some embodiments, the connection between the sixth wall 26 and the first wall 21 includes, but is not limited to, abutment, bonding, welding, or threaded connection. In some embodiments, the connection between the fifth wall 25 and the sixth wall 26 includes, but is not limited to, abutment, bonding, welding, or threaded connection.

[0160] In some embodiments, during the formation of the first wall 21, the second wall 22, the third wall 23, the fourth wall 24, the fifth wall 25 and the sixth wall 26, a cavity 111 may be formed inside the mounting beam 11 accordingly, and the cavity 111 includes a first sub-cavity 1111 and a second sub-cavity 1112.

[0161] In the above scheme, the mounting beam 11 has a simple structure and is easy to manufacture. The support member 1110 may include a sixth wall 26. By setting the sixth wall 26, the sixth wall 26 connects the fourth wall 24 and the first wall 21 that are disposed opposite to each other on the mounting beam 11, which can effectively improve the strength and rigidity of the mounting beam 11, reduce the risk of the battery 200 falling off, improve the deformation resistance of the bracket 10, and thus improve the driving reliability of the vehicle.

[0162] According to some embodiments of this application, see Figure 6 The sixth wall 26 is provided with a first bend 27 at the end away from the fourth wall 24. The first bend 27 extends along the second direction x and is connected to the first wall 21.

[0163] The first bend 27 may be a portion disposed at the end of the sixth wall 26 and extending along the second direction x to have a large connection area with the first wall 21. In some embodiments, the first bend 27 may extend toward the third wall 23. In other embodiments, the first bend 27 may extend toward the second wall 22.

[0164] In some embodiments, the connection between the first bend 27 and the first wall 21 includes, but is not limited to, abutment, bonding, welding, or threaded connection.

[0165] The above solution, by setting the first bending portion 27 to extend toward the third wall 23, enables the bracket 10 to bear the impact evenly, improves the deformation resistance of the bracket 10, reduces the risk of the battery 200 falling off, and thus improves the driving reliability of the vehicle.

[0166] According to some embodiments of this application, the first bend 27 extends from the end of the sixth wall 26 toward the third wall 23.

[0167] The above solution, by setting the first bending portion 27 to extend toward the third wall 23, enables the bracket 10 to bear the impact evenly, improves the deformation resistance of the bracket 10, reduces the risk of the battery 200 falling off, and thus improves the driving reliability of the vehicle.

[0168] According to some embodiments of this application, the end of the fifth wall 25 away from the third wall 23 is provided with a second bend 28, which extends along the first direction z and is connected to the sixth wall 26.

[0169] The second bend 28 may be a portion disposed at the end of the fifth wall 25 and extending along the first direction z to have a large connection area with the sixth wall 26. In some embodiments, the second bend 28 may extend toward the first wall 21.

[0170] In some embodiments, the connection between the second bend 28 and the sixth wall 26 includes, but is not limited to, abutment, bonding, welding, or threaded connection.

[0171] In the above scheme, by setting the second bending part 28, the connection area between the fifth wall 25 and the sixth wall 26 can be increased, the connection reliability between the fifth wall 25 and the sixth wall 26 can be improved, and the geometry of the cross-section of the hanging beam 11 has good load-bearing capacity. Under the condition of reducing the structural weight, the bracket 10 has good deformation resistance.

[0172] In other embodiments of this application, another type of mounting beam 11 is also provided; please refer to [link to relevant documentation]. Figure 7 , Figure 7 This is a schematic diagram of the cross-section of the mounting beam 11 in some other embodiments of this application.

[0173] The multiple sub-cavities 111 include a third sub-cavity, a fourth sub-cavity, and a fifth sub-cavity. The mounting beam 11 includes a seventh wall 31, an eighth wall 32, a ninth wall 33, a tenth wall 34, an eleventh wall 35, a twelfth wall 36, a thirteenth wall 37, and a fourteenth wall 38.

[0174] Along the second direction x, the two ends of the seventh wall 31 are connected to one end of the eighth wall 32 and one end of the ninth wall 33, respectively. Along the first direction z, the tenth wall 34 is arranged at an interval opposite to the seventh wall 31, and one end of the tenth wall 34 is connected to the other end of the eighth wall 32.

[0175] Along the first direction z, one end of the eleventh wall 35 is connected to the other end of the tenth wall 34, and the other end of the eleventh wall 35 is connected to one end of the twelfth wall 36. The twelfth wall 36 extends along the first direction z toward the eighth wall 32 and is connected to the first wall 21. Along the first direction z, one end of the thirteenth wall 37 is connected to the other end of the tenth wall 34, and the other end of the thirteenth wall 37 is connected to the tenth wall 34.

[0176] Along the first direction z, the fourteenth wall 38 and the seventh wall 31 are spaced apart. One end of the fourteenth wall 38 is connected to the other end of the ninth wall 33, and the other end of the fourteenth wall 38 is connected to the eleventh wall 35. The tenth wall 34, the eleventh wall 35, the twelfth wall 36, and the thirteenth wall 37 together form the third sub-chamber. The seventh wall 31, the eighth wall 32, the tenth wall 34, and the thirteenth wall 37 together form the fourth sub-chamber. The seventh wall 31, the ninth wall 33, and the fourteenth wall 38 together form the fifth sub-chamber.

[0177] The thirteenth wall 37 has a third bend 39 at its end away from the twelfth wall 36. The third bend 39 extends along the first direction z toward the eighth wall 32 and is connected to the tenth wall 34. The fourteenth wall 38 has a fourth bend 40 at its end away from the ninth wall 33. The fourth bend 40 extends along the second direction x and is connected to the eleventh wall 35.

[0178] According to some embodiments of this application, please refer to Figures 2-4 The bracket 10 also includes a connecting part 12, which is connected to the mounting beam 11 and is used to connect to the longitudinal beam 51 of the frame 50.

[0179] In some embodiments, the connecting portion 12 may be connected to the outer or inner side of the longitudinal beam 51 of the frame 50. The side of the longitudinal beam 51 facing another longitudinal beam 51 may be the inner side, and the side of the longitudinal beam 51 away from another longitudinal beam 51 may be the outer side. In some embodiments, the connecting portion 12 may be connected to the frame 50 by welding, threaded connection, or other connection methods.

[0180] The mounting beam 11 is directly or indirectly connected to the connecting part 12 so that the mounting beam 11 can be connected to the vehicle frame 50. In some embodiments, the mounting beam 11 can be connected to the connecting part 12 by welding, riveting, threaded connection or other connection methods. In some embodiments, the mounting beam 11 can be integrally formed with the connecting part 12, for example by roll forming or by bending process.

[0181] In the above solution, by setting the connecting part 12, the mounting beam 11 can be effectively connected to the longitudinal beam 51 of the frame 50, so that the mounting beam 11 can effectively support the battery 200 through the mounting part 110, reducing the risk of the battery 200 falling off and improving the driving reliability of the vehicle.

[0182] According to some embodiments of this application, see Figure 3 The mounting beam 11 is provided with two connecting parts 12, which are spaced apart. The two connecting parts 12 and the mounting beam 11 together form an upward-opening groove 120, which is used for the frame 50 to pass through.

[0183] In some embodiments, each mounting beam 11 is provided with two connecting portions 12, and the two connecting portions 12 are spaced apart (for example, the two connecting portions 12 are spaced apart along the length direction y of the mounting beam), so that the two connecting portions 12 are respectively connected to a pair of longitudinal beams 51 of the frame 50, for example, the outer side of the pair of longitudinal beams 51. That is, it can be understood that the two connecting portions 12 on each mounting beam 11 are respectively located on the outer side of the frame 50.

[0184] "The groove 120 is for the frame 50 to pass through" can be understood as the longitudinal beam 51 of the frame 50 can pass through the groove 120 formed between the two connecting parts 12 on the mounting beam 11.

[0185] In the above solution, by setting two connecting parts 12, on the one hand, it can form a groove 120 that avoids the longitudinal beam 51 of the frame 50; on the other hand, it can make the connecting parts 12 connect to the outer side of the corresponding longitudinal beam 51, that is, the two longitudinal beams 51 of the frame 50 are respectively connected by the corresponding connecting parts 12, so that the mounting unit and the frame 50 have a stable connection relationship, reducing the risk of the battery 200 falling off and improving the reliability of vehicle driving; furthermore, since there are two connecting parts 12, and the two connecting parts 12 are arranged laterally along the frame 50, that is, the mounting beam 11 can be provided with more mounting parts 110 to mount a larger battery 200 or more batteries 200, thereby effectively improving the vehicle's range.

[0186] According to some embodiments of this application, please refer to Figure 3 The bracket 10 also includes a rib 13, which is located on the side of the connecting part 12 away from the groove 120. The rib 13 connects the mounting beam 11 and the connecting part 12.

[0187] In some embodiments, the rib 13 may be a component connecting the mounting beam 11 and the connecting portion 12. In some embodiments, the rib 13 may be a component for strengthening the structural strength of the connecting portion 12, the mounting beam 11, and the frame 50. In some embodiments, the rib 13 may be a reinforcing rib, reinforcing beam, or reinforcing rib disposed between the connecting portion 12 and the mounting beam 11. In some embodiments, the rib 13 may be made of materials such as aluminum alloy, steel, or cast iron. In some embodiments, the materials of the rib 13, the connecting portion 12, and the mounting beam 11 may be the same or different. In some embodiments, the rib 13 may be connected to the connecting portion 12 by welding, threaded connection, or other connection methods. Alternatively, in some embodiments, the rib 13 may be integrally formed with the connecting portion 12. In some embodiments, the rib 13 may be connected to the mounting beam 11 by welding, threaded connection, or other connection methods. Alternatively, in some embodiments, the rib 13 may be integrally formed with the connecting portion 12 and the mounting beam 11.

[0188] In the above solution, by setting ribs 13 on the outside of the frame 50, the space between the connecting part 12 and the mounting beam 11 can be made reasonable, and the structural strength of the connecting part 12 and the mounting beam 11 can be improved, reducing the risk of the battery 200 falling off and improving the driving reliability of the vehicle.

[0189] According to some embodiments of this application, see Figure 8 , Figure 8This is a schematic diagram of a partial structure of the bracket 10 in some embodiments of this application. A bent portion 130 is provided at one end of the rib plate 13 near the mounting beam 11, and the rib plate 13 is connected to the mounting beam 11 through the bent portion 130.

[0190] The bent portion 130 is a component provided at one end of the rib 13 near the mounting beam 11. The bent portion 130 can be a component formed by bending or rolling the rib 13, and the bent portion 130 can be perpendicular to the main body of the rib 13. The bent portion 130 has a surface facing the mounting beam 11, which can be connected to the surface of the mounting beam 11.

[0191] In some embodiments, the rib 13 can be a double-layer plate structure, which can be composed of two plate-like structures stacked together. One plate-like structure is bent to form a bent portion 130, which is connected to the mounting beam 11. The other plate-like structure is bent to form a bent portion 130, which is also connected to the mounting beam 11. The bent portions 130 of the two plate-like structures are bent in opposite directions, for example, along the thickness direction of the rib 13, towards both sides of the rib 13.

[0192] In the above scheme, by providing a bending portion 130 at the end of the rib plate 13 near the mounting beam 11, the connection area between the rib plate 13 and the mounting beam 11 can be increased, thereby improving the connection reliability between the rib plate 13 and the mounting beam 11.

[0193] According to some embodiments of this application, a notch 131 is formed at one end of the rib plate 13 near the mounting beam 11, and the notch 131 is provided corresponding to the mounting part 110.

[0194] The notch 131 can be a recessed structure (or a groove-like structure) formed at the end of the rib 13. The notch 131 is provided corresponding to the mounting portion 110, providing space above the mounting portion 110. In some embodiments, the battery 200 has a mounting member corresponding to the mounting hole 1100, which is inserted into the mounting hole 1100 to connect the battery 200 and the bracket 10. In the height direction, the dimension of the mounting member extending beyond the upper surface of the mounting beam 11 can be less than or equal to the distance from the bottom of the notch 131 to the upper surface of the mounting beam 11.

[0195] In the above solution, by providing a notch 131 at one end of the rib plate 13 near the mounting beam 11, space above the mounting part 110 can be left free, reducing the risk of the battery 200 being interfered with by the rib plate 13 when it is mounted on the mounting part 110.

[0196] According to some embodiments of this application, please refer to Figure 3 The connecting part 12 is a flange provided on the rib plate 13, and the rib plate 13 and the connecting part 12 are arranged perpendicular to each other.

[0197] The phrase "the connecting part 12 is a flange set on the rib 13" can be understood as the connecting part 12 being formed by bending or rolling the rib 13, which means that the connecting part 12 and the rib 13 are an integral structure. The phrase "the rib 13 and the connecting part 12 are set perpendicular to each other" can be understood as the connecting part 12 being formed by bending the rib 13 at a 90-degree angle.

[0198] In the above scheme, the connecting part 12 can be a flange provided on the rib plate 13, that is, the connecting part 12 and the rib plate 13 are integrally formed, which can make the connecting part 12 and the rib plate 13 have high structural strength, effectively provide structural strength for the mounting beam 11, thereby effectively supporting the battery 200 and reducing the risk of the battery 200 falling off.

[0199] According to some embodiments of this application, the rib plate 13 includes a first rib plate 132 and a second rib plate 133 stacked together, and the connecting portion 12 includes a first sub-connecting portion 12 and a second sub-connecting portion 12. The first sub-connecting portion 12 is a flange disposed on the first rib plate 132, and the second sub-connecting portion 12 is a flange disposed on the second rib plate 133.

[0200] In some embodiments, the rib 13 can be a double-layer plate structure. For example, the rib 13 can be formed by stacking two plate-like structures. Alternatively, the rib 13 can be formed into a two-layer plate structure by bending or other processes from a single plate-like structure. See also... Figure 3 In the thickness direction of the rib 13, the rib 13 has a first rib 132 and a second rib 133 stacked on top of each other. The first sub-connecting portion 12 is a flange formed by bending or rolling the first rib 132, and the second sub-connecting portion 12 is a flange formed by bending or rolling the second rib 133. In the thickness direction of the rib 13, the first sub-connecting portion 12 and the second sub-connecting portion 12 are located on opposite sides of the rib 13.

[0201] In the above scheme, the rib plate 13 can be a double-layer plate structure. Since the rib plate 13 is a double-layer plate structure, the rib plate 13 can form two flanges facing opposite directions, that is, form the first sub-connection part 12 and the second sub-connection part 12, so that the rib plate 13 and the longitudinal beam 51 have a large connection area, improve the connection reliability between the rib plate 13 and the longitudinal beam 51, thereby improving the structural strength of the mounting beam 11, so that the mounting beam 11 can effectively support the battery 200 and reduce the risk of the battery 200 falling off.

[0204] The phrase “a receiving space is formed between two adjacent mounting beams 11 for accommodating at least a portion of the battery 200” can be understood as the receiving space formed between two adjacent mounting beams 11 being able to accommodate at least a portion of the structure of the battery 200, such as accommodating one battery 200, or accommodating a portion of a battery 200.

[0205] In the above scheme, the bracket 10 includes multiple mounting beams 11, such that at least a portion of the accommodating space for accommodating the battery 200 can be formed between two adjacent mounting beams 11, so that the battery 200 can be installed in the corresponding accommodating space in an orderly manner, thereby improving the battery swapping efficiency of the vehicle.
