Description

Technical Field

[0001] Embodiments of the present application relate to the field of vehicles, and more particularly, to a floor panel of a vehicle and a vehicle. Background Art

[0002] With the development of the times, electric vehicles have huge market prospects due to their high environmental protection, low noise, low cost of use and other advantages. They can effectively promote energy conservation and emission reduction, which is beneficial to the development and progress of society.

[0003] For electric vehicles, how to improve their manufacturing efficiency and vehicle performance is a technical problem that needs to be solved urgently. Summary of the Invention

[0004] The embodiments of the present application provide a vehicle floor and a vehicle that can have high manufacturing efficiency and performance.

[0005] In a first aspect, a floor panel of a vehicle is provided, comprising: a plate-shaped main body portion; and a side beam portion provided on at least one side of the plate-shaped main body portion, wherein the side beam portion and the plate-shaped main body portion are an integrally formed structure.

[0006] Through the technical solution of the embodiments of the present application, a plate-shaped main body and side beams are integrated into the vehicle's floor. These plate-shaped main body and side beams can be integrally installed in the vehicle via the floor, which helps reduce the number of parts required during vehicle production and improves vehicle manufacturing efficiency. Furthermore, the plate-shaped main body and side beams are integrally formed, eliminating the need for connectors to connect them. This also helps improve the mechanical strength of the two components, enhancing the reliability of the floor and the vehicle as a whole.

[0007] In some possible implementations, the plate-shaped main body is used as a wall of a battery box of a vehicle.

[0008] Through the technical solution of this embodiment, the plate-shaped main body of the bottom plate is reused as the wall of the vehicle's battery box, which is beneficial to further reduce the number of parts in the vehicle, improve the manufacturing efficiency of the vehicle, and reduce the weight of the battery in the vehicle to increase the energy density of the battery.

[0009] In some possible implementations, the side beam portion and the plate-shaped main body portion are integrally formed die-cast parts.

[0010] In the technical solution of this embodiment, the die-casting process has high production efficiency, and the products manufactured by the die-casting process have many advantages such as strong wear resistance, high strength, relatively complex molding structure, high dimensional accuracy, and low surface roughness. Therefore, the die-casting process is used to manufacture the one-piece molded side beam part and the plate-shaped main body part, so that the bottom plate has better mechanical properties and can meet the different application requirements of the vehicle.

[0011] In some possible implementations, the base plate further includes a thermal management portion, at least a portion of which is an integrally formed structure with the plate-shaped main body, and the thermal management portion is used to perform thermal management on an area corresponding to the plate-shaped main body.

[0012] Through the technical solution of this embodiment, at least a portion of the thermal management unit, the plate-shaped main body, and the side beam can be formed simultaneously through an integrated molding process. The vehicle's floorpan can integrate multiple functional components at once, further reducing the number of vehicle parts and improving manufacturing efficiency and performance. Furthermore, integrating the thermal management unit into the floorpan reduces the required installation space within the vehicle, thereby increasing available space within the vehicle while achieving thermal management of vehicle components to enhance vehicle performance.

[0013] In some possible embodiments, the thermal management part includes: a plate-shaped main body part and a sealing plate, the plate-shaped main body part and the sealing plate are stacked and fixedly connected, and a flow channel is formed between the plate-shaped main body part and the sealing plate, and the flow channel is used to accommodate fluid to perform thermal management on the area corresponding to the plate-shaped main body part.

[0014] This embodiment's technical solution designates the thermal management unit as a flow channel consisting of a plate-shaped main body and a sealing plate. This allows the plate-shaped main body to be reused as a component of the thermal management unit, reducing the number of parts required in vehicle manufacturing and improving the efficiency of thermal management unit manufacturing. Furthermore, the flow channel provides relatively uniform and reliable thermal management of vehicle components, further enhancing vehicle reliability.

[0015] In some possible implementations, a groove is formed in the plate-shaped main body, and the sealing plate is used to seal the groove to form a flow channel.

[0016] Through the technical solution of this embodiment, the groove can be formed in the plate-like main body more conveniently through an integrated molding process, and the sealing plate can adopt a conventional plate-like structure, which is conducive to further improving the manufacturing efficiency of the thermal management part in the vehicle.

[0017] In some possible implementations, the size of the sealing plate is the same as that of the plate-shaped main body.

[0018] In the technical solution of this embodiment, when the sealing plate is attached to the plate-like main body, the edges of the two can be flush with each other, thereby facilitating the fitting connection between the sealing plate and the plate-like main body. The sealing plate and the plate-like main body can have better sealing performance, and thus the flow channel between the sealing plate and the plate-like main body can have better reliability in use.

[0019] In some possible implementations, the edge of the sealing plate is welded to the edge of the plate-shaped main body.

[0020] In the technical solution of this embodiment, the sealing plate and the plate-like main body can be connected by welding, so that the two have higher connection reliability and sealing. Through this embodiment, it is beneficial to further improve the reliability of the flow channel between the sealing plate and the plate-like main body.

[0021] In some possible implementations, the thermal management portion further includes: a fluid interface pipe, the fluid interface pipe is connected to the flow channel, and the fluid interface pipe and the plate-shaped main body are an integrally formed structure.

[0022] In the technical solution of this embodiment, the fluid interface pipe does not need to be installed in the plate-like main body through additional mounting parts, and the fluid interface pipe has good connectivity and sealing with the flow channel formed in the plate-like main body, and the possibility of fluid leakage between the two is low.

[0023] In some possible implementations, the bottom plate further includes: a first reinforcement member, which is provided at the connection between the plate-shaped main body portion and the side beam portion.

[0024] In the technical solution of this embodiment, a first reinforcement is provided at the connection between the plate-like main body and the side beam portion. The first reinforcement can strengthen the relatively weak connection between the plate-like main body and the side beam portion, thereby improving the mechanical strength of the connection, reducing the influence of external force on the base plate, and further improving the reliability of the base plate.

[0025] In some possible implementations, the first reinforcement, the side beam portion, and the plate-shaped main body portion are an integrally formed structure.

[0026] Through the technical solution of this embodiment, the first reinforcement can also be integrally formed with the plate-like main body and the side beam portion, which is conducive to further reducing the number of parts in the vehicle and improving the manufacturing efficiency of the vehicle. The first reinforcement also does not require additional connecting parts to be installed between the plate-like main body and the side beam portion, which can improve the connection strength of the first reinforcement between the plate-like main body and the side beam portion.

[0027] In some possible implementations, the first reinforcement member includes at least one triangular reinforcement member, and two adjacent sides of the triangular reinforcement member are connected to the plate-shaped main body portion and the side beam portion.

[0028] In the technical solution of this embodiment, the first reinforcement includes a triangular reinforcement, which has high stability. The plate-like main body and the side beam part are connected by the triangular reinforcement, which is conducive to effectively improving the connection strength and connection stability between the plate-like main body and the side beam part.

[0029] In some possible embodiments, the side beam portion includes a side beam frame and multiple second reinforcements, the side beam frame and the multiple second reinforcements are an integrally formed structure, and the multiple second reinforcements are distributed in the side beam frame to enhance the strength of the side beam portion.

[0030] In the technical solution of this embodiment, the side beam portion is designed as an integrally formed side beam frame and a plurality of second reinforcement members. While the side beam portion has strong overall strength and better stability, the overall mass of the side beam portion is small and the design flexibility is high, which is beneficial to improving the comprehensive performance of the floor where the side beam portion is located and the vehicle.

[0031] In some possible implementations, at least some of the plurality of second reinforcement members are reinforcement members with varying thickness.

[0032] Through the technical solution of this embodiment, compared with the reinforcement with uniform thickness, the second reinforcement with varying thickness can reinforce different positions of the side beam portion to different degrees, so that the side beam portion can better adapt to the reinforcement requirements of different parts of the vehicle.

[0033] In some possible implementations, the plurality of second reinforcement members are distributed in a lattice or honeycomb pattern within the edge beam frame.

[0034] Through the technical solution of this embodiment, the multiple second reinforcements can have better structural stability in the side beam frame. The multiple second reinforcements can evenly and reliably improve the overall strength of the side beam part, thereby improving the overall performance of the floor.

[0035] In some possible implementations, the side member portion includes a rocker beam of a vehicle.

[0036] Through the technical solution of this embodiment, the rocker beam is integrated as a side beam portion with the plate-shaped main body portion, thereby reducing the number of parts in the vehicle manufacturing process and improving the manufacturing efficiency of the vehicle. In addition, the rocker beam and the plate-shaped main body portion can have better stability and connection strength, thereby improving the strength and reliability of the rocker beam in the vehicle.

[0037] In a second aspect, a vehicle is provided, comprising: a vehicle body, and the floor panel according to the first aspect or any possible embodiment of the first aspect, wherein the floor panel is installed below the vehicle body.

[0038] In some possible implementations, the vehicle further includes: a frame and a battery, the frame having an opening facing the bottom plate, and the bottom plate covering the opening to form a sealed space for accommodating the battery.

[0039] Through the technical solution of the embodiments of the present application, a plate-shaped main body and side beams are integrated into the vehicle's floor. These plate-shaped main body and side beams can be integrally installed in the vehicle via the floor, which helps reduce the number of parts required during vehicle production and improves vehicle manufacturing efficiency. Furthermore, the plate-shaped main body and side beams are integrally formed, eliminating the need for connectors to connect them. This also helps improve the mechanical strength of the two components, enhancing the reliability of the floor and the vehicle as a whole. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0056] The present application relates to vehicles, and more specifically, to the floor of a vehicle. In some related arts, the floor of the vehicle may also be referred to as the chassis of the vehicle. The floor of the vehicle and the vehicle body form the overall frame of the vehicle, and the floor may be used to support seats, users, and other components of the vehicle. The vehicle involved in the present application may be an electric vehicle, which may be equipped with a battery. In some specific implementations, the battery may be a power battery, which may be fixedly mounted to the floor of the electric vehicle to provide power for the electric vehicle.

[0057] The battery referred to in the embodiments of this application refers to a single physical module that includes one or more battery cells to provide higher voltage and capacity. For example, the battery referred to in this application may include a battery module or a battery pack. A battery generally includes a casing that encloses one or more battery cells. The casing prevents liquids or other foreign matter from affecting the charging or discharging of the battery cells.

[0058] In addition to the floor and body, the basic structure of a vehicle also includes various other structural components, such as rocker beams, front beams, and rear beams. These beam structures can be connected to the floor via connectors to enhance the mechanical strength of the entire vehicle frame. However, in this embodiment, the floor and beams are separate components. The strength of the connection between them is limited by factors such as the material of the connectors and the connection process, resulting in a weak connection, which affects the overall mechanical strength and reliability of the vehicle.

[0059] In view of this, an embodiment of the present application provides a floor panel of a vehicle, comprising: a plate-shaped main body portion and a side beam portion, wherein the side beam portion is arranged on at least one side of the plate-shaped main body portion, and the side beam portion and the plate-shaped main body portion are an integrally formed structure. Through the technical solution of the embodiment of the present application, the floor panel of the vehicle is integrated with the plate-shaped main body portion and the side beam portion, and the plate-shaped main body portion and the side beam portion can be installed in the vehicle as a whole through the floor panel, which is beneficial to reducing the number of parts in the vehicle production process and improving the manufacturing efficiency of the vehicle. In addition, the plate-shaped main body portion and the side beam portion are integrally formed, and there is no need for connectors to connect the two, which is also beneficial to improving the mechanical strength between the two as a whole, and improving the reliability of the floor panel and the vehicle as a whole.

[0060] The technical solutions described in the embodiments of the present application can be applied to various types of vehicles, such as fuel vehicles, gas vehicles or new energy vehicles, among which new energy vehicles can be pure electric vehicles, hybrid vehicles or extended-range vehicles, etc.

[0061] As an example, Figure 1 A structural schematic diagram of a vehicle 1 provided in one embodiment of the present application is shown.

[0062] like Figure 1 As shown, the interior of the vehicle 1 may be provided with a motor 40, a controller 30, and a battery 10. The controller 30 is used to control the battery 10 to power the motor 40. For example, the battery 10 may be provided at the bottom, front, or rear of the vehicle 1. The battery 10 may be used to power the vehicle 1. For example, the battery 10 may serve as an operating power source for the vehicle 1 and may be used for the circuit system of the vehicle 1, such as for starting, navigating, and operating the vehicle 1. In another embodiment of the present application, the battery 10 may serve not only as an operating power source for the vehicle 1, but also as a driving power source for the vehicle 1, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1.

[0063] Figure 2 A schematic structural diagram of a vehicle floor panel 100 provided in an embodiment of the present application is shown.

[0064] like Figure 2 As shown, in an embodiment of the present application, the floor 100 of the vehicle includes: a plate-shaped main body portion 110 and a side beam portion 120, wherein the side beam portion 120 is arranged on at least one side of the plate-shaped main body portion 110, and the side beam portion 120 and the plate-shaped main body portion 110 are an integrally formed structure.

[0065] Specifically, in the base plate 100, the plate-shaped main body 110 is a plate-shaped member with high strength and rigidity. It serves as the main body of the vehicle and can be used to support the seat, user, and other components in the vehicle. By way of example and not limitation, the plate-shaped main body 110 can be a metal member with high mechanical rigidity and strength.

[0066] As an example, in Figure 2 In the illustrated embodiment, there can be two side beams 120, which can be disposed on either side of the plate-shaped main body 110. In other examples, the number of side beams 120 can be other numbers. For example, the number of side beams 120 can be designed based on the shape of the plate-shaped main body 110, and this embodiment of the present application does not specifically limit this.

[0067] The side beam 120 can also have a certain strength and hardness. When the side beam 120 and the plate-shaped main body 110 are connected to each other as a whole, the side beam 120 can strengthen and support the plate-shaped main body 110 in its extending direction to improve the overall strength of the plate-shaped main body 110.

[0068] In the embodiment of the present application, the plate-shaped main body portion 110 and the side beam portion 120 in the base plate 100 are an integrally formed structure, that is, the two can be manufactured and formed by the same process, and no additional connecting parts and connecting processes are required between the two. Therefore, the connection strength between the plate-shaped main body portion 110 and the side beam portion 120 will not be limited by the connecting parts and the connecting process, and the plate-shaped main body portion 110 and the side beam portion 120 as a whole can have higher mechanical strength.

[0069] In some specific implementations, the one-piece molding process for manufacturing the plate-shaped main body portion 110 and the side beam portion 120 can be specifically selected based on the materials of the two and manufacturing requirements. By way of example and not limitation, the one-piece molding process can include: injection molding, stamping, die-casting, CNC (Computer Numerical Control) molding, etc.

[0070] Through the technical solution of the embodiment of the present application, the vehicle floor panel 100 integrates a plate-shaped main body portion 110 and a side beam portion 120. The plate-shaped main body portion 110 and the side beam portion 120 can be integrally installed in the vehicle through the floor panel 100, which helps reduce the number of parts in the vehicle production process and improves vehicle manufacturing efficiency. In addition, the plate-shaped main body portion 110 and the side beam portion 120 are integrally formed, and no connectors are required to connect them. This also helps to improve the mechanical strength of the two as a whole, thereby improving the reliability of the floor panel 100 and the vehicle as a whole.

[0071] In some possible implementations, the side beam portion 120 and the plate-shaped main body portion 110 are integrally formed die-cast parts. In other words, the side beam portion 120 and the plate-shaped main body portion 110 can be integrally formed through a die-casting process.

[0072] Specifically, die casting is a metal casting process that uses a mold cavity to apply high pressure to a molten metal, forming the metal into a casting within the mold. This die casting process offers high production efficiency, and the resulting products exhibit numerous advantages, including strong wear resistance, high strength, relatively complex molding structures, high dimensional accuracy, and low surface roughness. Therefore, using this die casting process to manufacture the integrally formed side beam portion 120 and plate-shaped main body portion 110 can ensure that the floor panel 100 has superior mechanical properties and can meet the diverse application requirements of vehicles.

[0073] In some embodiments, the vehicle may be equipped with a battery, and the plate-shaped main body 110 of the base plate 100 may be a wall of a battery box.

[0074] In this embodiment, Figure 3 A schematic structural diagram showing the cooperation between the base plate 100 and the battery box 200 provided in an embodiment of the present application is shown.

[0075] like Figure 3 As shown, the battery box 200 may include an upper cover 210 and a frame 220. The upper cover 210 may be one of the walls of the battery box 200. Figure 3 In the illustrated embodiment, the upper cover 210 may be the plate-shaped main body 110 in the base plate 100 . In other words, the plate-shaped main body 110 may be reused as the upper cover 210 of the battery box 200 .

[0076] In some embodiments, the frame 220 may be a hollow rectangular parallelepiped with one open surface, and the plate-shaped main body 110 may cover the open surface to form a sealed cavity for accommodating the battery. In other embodiments, the frame 220 may also be a hollow frame structure with two open surfaces on opposite sides, with the plate-shaped main body 110 covering one of the two open surfaces. The other open surface may be equipped with a bottom guard plate or other structural member. The bottom guard plate, the plate-shaped main body 110, and the frame 220 together form a sealed cavity for accommodating the battery.

[0077] Through the technical solution of the embodiment of the present application, the plate-shaped main body 110 in the base plate 100 is reused as the wall of the battery box of the vehicle, which is beneficial to further reduce the number of parts in the vehicle, improve the manufacturing efficiency of the vehicle, and help reduce the weight of the battery in the vehicle to increase the energy density of the battery.

[0078] Figure 4 Another schematic structural diagram of the base plate 100 provided in an embodiment of the present application is shown.

[0079] like Figure 4 As shown, in the embodiment of the present application, the base plate 100 further includes: a thermal management portion 130 , at least a portion of which is an integrally formed structure with the plate-shaped main body portion 110 , and the thermal management portion 130 is used to perform thermal management on the area corresponding to the plate-shaped main body portion 110 .

[0080] Specifically, the base plate 100 provided in the embodiment of the present application is further integrated with a thermal management unit 130 , which can perform thermal management on components located near the plate-shaped main body 110 in the vehicle, that is, cool and / or heat the components.

[0081] As an example, Figure 2As shown, when the plate-shaped main body 110 of the bottom plate 100 serves as the wall of the battery case 200, the thermal management unit 130 can perform thermal management on the batteries disposed inside the battery case 200 to improve the operating performance of the batteries and reduce the possibility of battery failures such as thermal runaway.

[0082] In the embodiments of the present application, the thermal management unit 130 can be implemented in various ways. As an example and not limitation, the thermal management unit 130 can be an air-cooled structure, a liquid-cooled structure, or a natural convection heat dissipation structure. If the thermal management unit 130 is an air-cooled structure, the thermal management unit 130 can be a fan. If the thermal management unit 130 is a liquid-cooled structure, the thermal management unit 130 can be a water-cooled pipe or a water-cooled plate. If the thermal management unit 130 is a natural convection heat dissipation structure, the thermal management unit 130 can be a heat sink.

[0083] At least a portion of the thermal management unit 130 is integrally formed with the plate-shaped main body 110. Specifically, at least a portion of the thermal management unit 130, the plate-shaped main body 110, and the side beam 120 can be formed simultaneously through an integrated molding process. The vehicle's floor panel 100 can integrate multiple functional components, further reducing the number of vehicle parts and improving manufacturing efficiency and performance. Furthermore, integrating the thermal management unit 130 into the floor panel 100 reduces the required installation space within the vehicle, thereby increasing available space within the vehicle while enabling thermal management of vehicle components to enhance vehicle performance.

[0084] Continue to see Figure 4 As shown, in some embodiments, the thermal management part 130 may include a plate-shaped main body part 110 and a sealing plate 132, and the plate-shaped main body part 110 and the sealing plate 132 are stacked and fixedly connected, and a flow channel is formed between the plate-shaped main body part 110 and the sealing plate 132, and the flow channel is used to accommodate fluid to perform thermal management on the area corresponding to the plate-shaped main body part 110.

[0085] Specifically, in this embodiment, the thermal management unit 130 may be a liquid-cooled thermal management component. The flow channels within the thermal management unit 130 may contain water or other types of liquids to achieve thermal management. Of course, in addition to liquids such as water, the flow channels within the thermal management unit 130 may also contain gaseous fluids such as air. The thermal management unit 130 may utilize liquid and / or gaseous fluids to thermally manage components within the vehicle.

[0086] In this embodiment, the plate-shaped main body 110 can be used as part of the thermal management unit 130, thereby reducing the number of parts in the thermal management unit 130. In some embodiments, a groove 131 can be formed in the plate-shaped main body 110, and a sealing plate 132 is used to block the groove 131 to form a flow channel. In other embodiments, a groove can also be formed in the sealing plate 132, and the plate-shaped main body 110 is used to block the groove in the sealing plate 132 to form a flow channel.

[0087] Through the technical solution of this embodiment, the thermal management unit 130 is designed as a flow channel consisting of a plate-shaped main body 110 and a sealing plate 132. The plate-shaped main body 110 can be reused as a component of the thermal management unit 130, reducing the number of parts in the vehicle manufacturing process and improving the manufacturing efficiency of the thermal management unit 130 in the vehicle. The flow channel also provides relatively uniform and reliable thermal management of vehicle components, further improving vehicle reliability.

[0088] In the case where the groove 131 is provided in the plate-shaped main body 110, the groove 131 can be formed in the plate-shaped main body 110 by an integral molding process. Optionally, the position and shape of the groove 131 in the plate-shaped main body 110 can be designed according to actual needs. Figure 4 In the illustrated embodiment, the groove 131 may be serpentinely disposed in the plate-shaped main body 110 , that is, the groove 131 may form a serpentine flow channel, the length of which may be designed to be relatively long, thereby performing sufficient thermal management on components in the vehicle.

[0089] Through the technical solution of the embodiment of the present application, the groove 131 can be formed in the plate-like main body 110 more conveniently through an integrated molding process, and the sealing plate 132 can adopt a conventional plate-like structure, which is conducive to further improving the manufacturing efficiency of the thermal management part 130 in the vehicle.

[0090] In some embodiments, the size of the sealing plate 132 may be the same as the size of the plate-shaped main body 110 .

[0091] Specifically, in this embodiment, when the sealing plate 132 is attached to the plate-like main body 110, the edges of the two can be flush with each other, thereby facilitating the fitting connection between the sealing plate 132 and the plate-like main body 110. The sealing plate 132 and the plate-like main body 110 can have better sealing performance, and thus the flow channel between the sealing plate 132 and the plate-like main body 110 can have better reliability in use.

[0092] In some embodiments, an edge of the sealing plate 132 is welded to an edge of the plate-shaped main body 110 .

[0093] Specifically, in this embodiment, the sealing plate 132 and the plate-like main body 110 can both be made of metal, which has high mechanical strength and hardness. The sealing plate 132 and the plate-like main body 110 can be connected by welding, thereby achieving a high connection reliability and sealing performance. This embodiment further improves the reliability of the flow channel between the sealing plate 132 and the plate-like main body 110.

[0094] Figure 5 Shown Figure 4 A partially enlarged schematic diagram of part A in the illustrated embodiment.

[0095] like Figure 5 As shown, in the embodiment of the present application, the thermal management portion 130 further includes: a fluid interface pipe 133 , the fluid interface pipe 133 is connected to the flow channel, and the fluid interface pipe 133 and the plate-shaped main body portion 110 are an integrally formed structure.

[0096] As an example, Figure 5 1 shows two fluid interface pipes 133 , which are a fluid inlet pipe and a fluid outlet pipe respectively. Through the two fluid interface pipes 133 , the fluid can circulate in the flow channel to further enhance the thermal management effect of the thermal management unit 130 .

[0097] In other alternative examples, the thermal management unit 130 may include another number of fluid interface conduits 133. For example, the thermal management unit 130 may include only one fluid interface conduit 133, which may serve as both a fluid inlet conduit and a fluid outlet conduit. In another example, the thermal management unit 130 may include three or more fluid interface conduits 133, which may be distributed throughout the plate-shaped main body 110 and interconnected with the flow channels.

[0098] In the embodiment of the present application, the fluid interface conduit 133 can also be manufactured in an integral molding process within the plate-shaped main body 110. In some implementations, the plate-shaped main body 110, the groove 131, and the fluid interface conduit 133 can be integrally formed through a die-casting process. The fluid interface conduit 133 does not require additional mounting components to be installed within the plate-shaped main body 110. Furthermore, the fluid interface conduit 133 maintains good connectivity and sealing with the flow channel formed within the plate-shaped main body 110, minimizing the likelihood of fluid leakage between the two.

[0099] Figure 6 Another schematic structural diagram of the base plate 100 provided in an embodiment of the present application is shown.

[0100] like Figure 6As shown, in the embodiment of the present application, the bottom plate 100 may further include: a first reinforcement 140 , which is arranged at the connection between the plate-shaped main body portion 110 and the side beam portion 120 .

[0101] In some embodiments, the plate-shaped main body portion 110 may be arranged perpendicular to the wall of the side beam portion 120. In this case, the connection between the plate-shaped main body portion 110 and the side beam portion 120 is relatively weak and easily affected by external forces, causing the connection to break.

[0102] In view of this, the embodiment of the present application provides a first reinforcement 140 at the connection between the plate-shaped main body portion 110 and the side beam portion 120. The first reinforcement 140 can strengthen the relatively weak connection between the plate-shaped main body portion 110 and the side beam portion 120, thereby improving the mechanical strength of the connection, reducing the impact of external forces on the base plate 100, and further improving the reliability of the base plate 100.

[0103] Optionally, in the embodiment of the present application, the first reinforcement 140 can be designed into various shapes or structures according to needs. As an example but not a limitation, the first reinforcement 140 can be a long strip reinforcement, a triangular reinforcement, etc.

[0104] In some embodiments, the first reinforcement 140 , the side beam portion 120 , and the plate-shaped main body portion 110 are an integrally formed structure.

[0105] Specifically, in this embodiment, the first reinforcement 140 can be integrally formed with the plate-shaped main body 110 and the side beam 120. As an example and not a limitation, the first reinforcement 140, the plate-shaped main body 110 and the side beam 120 can be integrally formed by a die-casting process.

[0106] Through the technical solution of this embodiment, the first reinforcement 140 can also be integrally formed with the plate-shaped main body portion 110 and the side beam portion 120, which is conducive to further reducing the number of parts in the vehicle and improving the manufacturing efficiency of the vehicle. The first reinforcement 140 also does not require additional connecting parts to be installed between the plate-shaped main body portion 110 and the side beam portion 120, which can improve the connection strength of the first reinforcement 140 between the plate-shaped main body portion 110 and the side beam portion 120.

[0107] In some specific implementations, such as Figure 6 As shown, the first reinforcement 140 includes at least one triangular reinforcement, and two adjacent sides of the triangular reinforcement are connected to the plate-shaped main body portion 110 and the side beam portion 120 .

[0108] Specifically, in this embodiment, the first reinforcement 140 includes a triangular reinforcement, which has high stability. The plate-like main body portion 110 and the side beam portion 120 are connected by the triangular reinforcement, which is beneficial to effectively improve the connection strength and connection stability between the plate-like main body portion 110 and the side beam portion 120.

[0109] Alternatively, when the plate-shaped main body 110 is perpendicular to the wall of the side beam 120, the triangular reinforcement member may be a right-angled triangular reinforcement member, with two right-angled sides of the right-angled triangular reinforcement member respectively connected to the plate-shaped main body 110 and the side beam 120. Of course, when the plate-shaped main body 110 is not perpendicular to the wall of the side beam 120, the triangular reinforcement member may also be an acute-angled triangle reinforcement member or an obtuse-angled triangle reinforcement member.

[0110] When the first reinforcement 140 includes a plurality of triangular reinforcements, the plurality of triangular reinforcements may be arranged equidistantly along the extension direction of the side beam portion 120 , thereby providing uniform reinforcement and support between the side beam portion 120 and the plate-shaped main body portion 110 .

[0111] It can be understood that when the base plate 100 includes multiple side beam portions 120, a first reinforcement member 140 can be provided at the connection between each side beam portion 120 and the plate-like main body portion 110, so as to enhance the mechanical strength between each side beam portion 120 and the plate-like main body portion 110.

[0112] Figure 7 Another schematic structural diagram of the base plate 100 provided in an embodiment of the present application is shown.

[0113] like Figure 7 As shown, in an embodiment of the present application, the side beam portion 120 includes a side beam frame 121 and a plurality of second reinforcements 122. The side beam frame 121 and the plurality of second reinforcements 122 are an integrally formed structure. The plurality of second reinforcements 122 are distributed in the side beam frame 121 to enhance the strength of the side beam portion 120.

[0114] Optionally, in the side beam portion 120 provided in the embodiment of the present application, the side beam frame 121 is a hollow frame. In some embodiments, the side beam frame 121 can be a hollow frame with an opening, for example, Figure 7 As shown, the side beam frame 121 is a hollow frame with three openings. Alternatively, in other embodiments, the side beam frame 121 can also be a hollow frame with an external closure. The embodiment of the present application does not limit the specific form design of the side beam frame 121.

[0115] Multiple second reinforcements 122 are distributed throughout the hollow side beam frame 121 to enhance the overall strength of the side beam portion 120 and reduce the impact and shock of external forces on the side beam portion 120. The multiple second reinforcements 122 and the side beam frame 121 can be formed using an integrated molding process, resulting in superior stability and design flexibility. While enhancing the overall strength of the side beam portion 120, the multiple second reinforcements 122 in the side beam portion 120 can be flexibly designed to suit different application scenarios and usage requirements.

[0116] In the technical solution provided in the embodiment of the present application, the side beam portion 120 is designed as an integrally formed side beam frame 121 and a plurality of second reinforcements 122. While the side beam portion 120 has strong overall strength and better stability, the overall mass of the side beam portion 120 is small and the design flexibility is high, which is beneficial to improving the comprehensive performance of the bottom plate 100 where the side beam portion 120 is located and the vehicle.

[0117] In some embodiments, at least some of the second reinforcement members 122 in the plurality of second reinforcement members 122 are reinforcement members with varying thickness.

[0118] Specifically, in this embodiment, since the second reinforcement members 122 can be formed through an integral molding process, the structural design of the second reinforcement members 122 can be relatively flexible. At least some of the plurality of second reinforcement members 122 can be reinforcement members with varying thicknesses. For example, at least some of the second reinforcement members 122 can be plate-like members or strip-like members with varying thicknesses.

[0119] Through the technical solution of this embodiment, compared with the reinforcement with uniform thickness, the second reinforcement 122 with varying thickness can reinforce different positions of the side beam portion 120 to different degrees, so that the side beam portion 120 can better adapt to the reinforcement requirements of different parts of the vehicle.

[0120] In some embodiments, the plurality of second reinforcement members 122 may be distributed in a lattice or honeycomb pattern within the side beam frame 121 .

[0121] For example, Figure 7 As shown, the plurality of second reinforcement members 122 may be a plurality of plate-like reinforcement members, which are arranged in a crisscross pattern to form a lattice-like distribution within the side beam frame 121. In other examples, the plurality of second reinforcement members 122 may also be arranged in a honeycomb pattern or other regular or irregular pattern within the side beam frame 121 to reinforce the side beam portion 120.

[0122] Through the technical solution of this embodiment, the multiple second reinforcements 122 can have better structural stability in the side beam frame 121. The multiple second reinforcements 122 can evenly and reliably improve the overall strength of the side beam portion 120, thereby improving the overall performance of the floor 100.

[0123] In the above embodiments of the present application, the side beam portion 120 may include a rocker beam of the vehicle.

[0124] Specifically, the sill beam of a vehicle is a beam located below a vehicle door. A vehicle may include two sill beams, which may be distributed on both sides of the vehicle.

[0125] In some related technologies, the sill beam and vehicle floor are separate components, requiring multiple installation steps to install each separately, impacting vehicle manufacturing efficiency. Furthermore, the separation of the sill beam and vehicle floor also affects its strength and reliability within the vehicle.

[0126] Therefore, in the present application, the rocker beam is integrated as the side beam portion 120 with the plate-shaped main body portion 110, thereby reducing the number of parts in the vehicle manufacturing process and improving the manufacturing efficiency of the vehicle. In addition, the rocker beam and the plate-shaped main body portion 110 can have better stability and connection strength, thereby improving the strength and reliability of the rocker beam in the vehicle.

[0127] In some alternative embodiments, the side beam portion 120 may also include a front beam and / or a rear beam of the vehicle, wherein the front beam is a beam structure located at the front of the vehicle, and the rear beam is a beam structure located at the rear of the vehicle.

[0128] Figure 8 Another schematic structural diagram showing the cooperation between the base plate 100 provided in an embodiment of the present application and the battery box 200 in the vehicle is shown.

[0129] like Figure 8 As shown, in the embodiment of the present application, the bottom plate 100 includes: a plate-shaped main body portion 110 , a side beam portion 120 , a sealing plate 132 and a first reinforcement member 140 .

[0130] Alternatively, the side beam portion 120 may be a vehicle rocker beam, and the bottom plate 100 may be integrated with the plate-shaped main body portion 110. For example, the plate-shaped main body portion 110 and the rocker beam are both made of metal and may be integrally formed by a die-casting process.

[0131] In this embodiment of the present application, the plate-shaped main body 110 and the sealing plate 132 are stacked and fixedly connected. A flow channel is formed between the plate-shaped main body 110 and the sealing plate 132. This flow channel can accommodate fluid to achieve thermal management. In other words, in this embodiment of the present application, the thermal management unit can include the plate-shaped main body 110 and the sealing plate 132, and the plate-shaped main body 110 can be reused as a component of the thermal management unit.

[0132] Alternatively, as Figure 8 As shown, a groove 131 is formed in the plate-shaped main body 110. After the sealing plate 132 is stacked and attached to the plate-shaped main body 110, the sealing plate 132 blocks the groove 131 in the plate-shaped main body 110 to form a flow channel. The groove 131 can be formed in the plate-shaped main body 110 through an integral molding process (e.g., a die-casting process).

[0133] The first reinforcement member 140 is provided at the connection between the plate-shaped main body portion 110 and the side beam portion 120 to reinforce the connection between the plate-shaped main body portion 110 and the side beam portion 120. Figure 8 In the illustrated example, the first reinforcement 140 includes a plurality of triangular reinforcements, which extend along the length direction of the side beam portion 120 and are equidistantly distributed between the plate-shaped main body portion 110 and the side beam portion 120 .

[0134] In the side beam portion 120, a plurality of second reinforcement members 122 are distributed in the side beam frame 121, so that the side beam portion 120 has high strength and low weight. Figure 8 As shown, the second reinforcement members 122 are arranged in a lattice-like distribution in the side beam frame 121 . Alternatively, the second reinforcement members 122 may also be arranged in a honeycomb-like or other shapes in the side beam frame 121 .

[0135] Furthermore, in the embodiment of the present application, the base plate 100 can be applied to a vehicle having a battery, and the plate-shaped main body 110 in the base plate 100 can be reused as a wall of the battery box 200 in the vehicle, for example, Figure 8 As shown, the plate-shaped main body 110 can be reused as the upper cover of the battery box 200 .

[0136] The battery box 200 may include a frame 220, which may be a hollow frame structure with two opposite sides being open. The plate-shaped main body 110 covers one of the two open sides, and the other open side may be equipped with a bottom guard plate ( Figure 8 The bottom guard plate, the plate-shaped main body 110 and the frame 220 together form a closed cavity for accommodating the battery.

[0137] In some embodiments, the frame 220 can be connected to the side beam portion 120 fixed in the bottom plate 100 to achieve the installation of the battery box 200 in the vehicle. As an example, Figure 8 As shown, extensions are formed on both sides of the frame 220, and grooves that match the extensions are formed in the side beam 120. After the extensions of the frame 220 are accommodated in the grooves in the side beam 120, the two can be installed and connected by connecting parts such as bolts.

[0138] The present application also provides a vehicle, comprising a vehicle body and the base plate 100 provided in any one of the above embodiments, wherein the base plate 100 is installed below the vehicle body.

[0139] Specifically, the vehicle body can be the vehicle's frame, which forms the vehicle's overall appearance. The body may include, for example, windows, doors, a cockpit, a passenger compartment, an engine compartment, and a luggage compartment. The floor panel 100 is mounted beneath the vehicle body to form the overall structural framework of the vehicle.

[0140] In some embodiments, the vehicle may be, for example, Figure 1 The vehicle 1 shown in FIG. The vehicle 1 may include a battery 10. The vehicle 1 may further include a frame 220 having an opening toward the bottom plate 100, and the bottom plate 100 covers the opening to form a sealed space for accommodating the battery 10.

[0141] Specifically, in this embodiment, the frame 220 and the bottom plate 100 can together form a battery box for accommodating the battery 10. The mutual cooperation between the frame 220 and the bottom plate 100 can be seen above. Figure 3 or Figure 8 The description of the embodiments shown will not be repeated here.

[0142] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and components may be substituted with equivalents without departing from the scope of the present application. In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
