Description

Technical Field

[0001] This application relates to the field of vehicles, and more particularly to a vehicle body and a vehicle having the vehicle body. Background Technology

[0002] In related technologies, the vehicle body includes a front engine compartment assembly, which in turn includes a front bulkhead structure. This bulkhead structure is formed by splicing together multiple components, resulting in low integration and poor weight reduction. Furthermore, in a frontal collision, components within the front engine compartment assembly are prone to impacting the bulkhead structure. Deformation of the bulkhead structure can cause these components to intrude into the passenger compartment, potentially injuring occupants. Additionally, in electric vehicles, the battery pack is located below the passenger compartment. In a frontal collision, if components from the front engine compartment assembly intrude into the passenger compartment, they can compress the battery pack, reducing its reliability. Utility Model Content

[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, one object of this application is to propose a vehicle body that, by fixing a reinforcing structure to the front bulkhead structure, reduces the intrusion of components in the front engine compartment assembly into the passenger compartment of the vehicle in the event of a frontal collision, thereby reducing the risk of injury to occupants in the passenger compartment. Furthermore, when the vehicle is an electric vehicle, it helps to improve the reliability of the battery device, thereby improving the driving reliability of the vehicle.

[0004] This application also proposes a vehicle.

[0005] In a first aspect, embodiments of this application provide a vehicle body, including:

[0006] Front bulkhead structure, which extends along the width of the vehicle body;

[0007] The reinforcing structure has a reinforcement structure on at least one side of the front bulkhead structure along the length of the vehicle body. The reinforcement structure is fixed to the front bulkhead structure and extends along the width of the vehicle body.

[0008] In the above technical solution, by fixing the reinforcing structure to the front bulkhead structure, the structural strength of the front bulkhead structure is improved. In the event of a frontal collision, the front bulkhead structure can reliably support the components in the front engine compartment assembly of the vehicle body, reduce the amount of intrusion of the components in the front engine compartment assembly into the passenger compartment of the vehicle, reduce the risk of injury to the occupants in the passenger compartment, and when the vehicle is an electric vehicle, it can also reduce the risk of the battery device being crushed, which is conducive to improving the reliability of the battery device and thus improving the driving reliability of the vehicle.

[0009] In some embodiments, the front bulkhead structure includes: a front bulkhead middle structure and two front bulkhead end structures, the two front bulkhead end structures being opposite to and spaced apart along the width direction of the vehicle body, the front bulkhead middle structure being connected between the two front bulkhead end structures, and the two ends of the reinforcing structure extending to the respective front bulkhead end structures along the extension direction of the front bulkhead structure.

[0010] In the above technical solution, along the extension direction of the front bulkhead structure, the two ends of the reinforcing structure extend to the corresponding front bulkhead end structures, which enables the reinforcing structure to cover the entire area of ​​the middle front bulkhead structure along the extension direction of the front bulkhead structure. This allows the reinforcing structure to correspond with the installation space along the length of the vehicle body. In the event of a frontal collision, this further reduces the intrusion of components in the front engine compartment assembly into the passenger compartment, further reducing the risk of injury to occupants. It also further reduces the risk of the battery device being crushed, which is more conducive to improving the reliability of the battery device and thus further improving the driving reliability of the vehicle.

[0011] In some embodiments, a mounting groove extending along the extension direction of the front bulkhead is formed on the side of the front bulkhead facing the reinforcing structure, and at least a portion of the reinforcing structure is disposed within the mounting groove.

[0012] In the above technical solution, by having at least a portion of the reinforcing structure housed within the mounting groove, the overall structure of the front bulkhead and the reinforcing structure becomes more compact. This reduces the overall volume of the front bulkhead and the reinforcing structure, lowers the overall assembly space, and allows the inner wall of the mounting groove to limit the reinforcing structure when it contacts the inner wall, reducing the risk of deformation and enhancing its resistance to deformation. This further improves the structural strength of the front bulkhead. In the event of a frontal collision, this further reduces the intrusion of components from the front engine compartment into the passenger compartment, further reducing the risk of injury to occupants and minimizing the risk of battery compression, thereby further improving vehicle reliability.

[0013] In some embodiments, multiple mounting slots and multiple reinforcing structures are provided, and the multiple mounting slots and multiple reinforcing structures are assembled in a one-to-one correspondence.

[0014] In the above technical solution, by assembling the mounting slots and reinforcing structures one-to-one, the reinforcing structures can be reliably assembled into the corresponding mounting slots. The inner wall of the mounting slots can reliably limit the corresponding reinforcing structures, further reducing the risk of deformation of the reinforcing structures, further improving the ability of the reinforcing structures to resist deformation, and further improving the structural strength of the front structure.

[0015] In some embodiments, the reinforcing structure is fixedly provided with a mounting sleeve, the mounting sleeve having a mounting hole, and fasteners passing through the mounting hole and connected to the front bulkhead structure, so that the reinforcing structure is fixed to the front bulkhead structure.

[0016] In the above technical solution, by fixing the reinforcing structure with an installation sleeve, and fasteners passing through the installation holes and connected to the front bulkhead structure, the reinforcing structure can be reliably fixed to the front bulkhead structure, thereby making the reinforcing structure and the front bulkhead structure form a whole. When the vehicle is involved in a frontal collision, the front bulkhead structure can effectively resist the impact of the components inside the front engine compartment assembly.

[0017] In some embodiments, there are multiple mounting sleeves, which are arranged along the extension direction of the reinforcing structure.

[0018] In the above technical solution, by setting multiple mounting sleeves, multiple fasteners can be used simultaneously to reliably fix the reinforcing structure to the front bulkhead structure, thereby improving the connection strength between the reinforcing structure and the front bulkhead structure, reducing the risk of separation between the reinforcing structure and the front bulkhead structure, and thus helping to improve the reliability of the vehicle body.

[0019] In some embodiments, the reinforcing structure is constructed as a reinforcing beam.

[0020] In the above technical solution, by constructing the reinforcing structure as a reinforcing beam, the structure of the reinforcing structure can be simplified, making it easier to manufacture and improve the production efficiency of the reinforcing structure. This, in turn, helps to improve the production efficiency of the car body. Furthermore, due to the simplicity of the reinforcing structure, labor input costs can be saved, thereby reducing the manufacturing cost of the car body.

[0021] In some embodiments, the reinforcing structure forms a buffer space.

[0022] In the above technical solution, by forming a buffer space through the reinforcement structure, while satisfying the requirement of improving the structural strength of the front structure, the reinforcement structure is conducive to the deformation and energy absorption of the reinforcement structure when it is compressed, reducing the risk of stress concentration in the reinforcement structure, thereby reducing the risk of fracture of the reinforcement structure. Furthermore, when the reinforcement structure is impacted, it is conducive to the reinforcement structure to transmit force in multiple directions.

[0023] In some embodiments, the vehicle body further includes an energy-absorbing structure, wherein the energy-absorbing structure is provided within the buffer space.

[0024] In the above technical solution, by setting the energy-absorbing structure in the buffer space, the energy-absorbing structure can absorb energy when the reinforced structure is compressed, further reducing the risk of stress concentration in the reinforced structure, thereby further reducing the risk of fracture of the reinforced structure.

[0025] In some embodiments, the energy-absorbing structure includes at least one of an energy-absorbing box, a buffer frame, a spring, and an airbag component.

[0026] In the above technical solution, by including at least one of the following components—energy-absorbing box, buffer frame, spring, and airbag component—the energy-absorbing structure can have energy-absorbing performance, thereby meeting the working requirements and improving the energy-absorbing effect. After being impacted, the energy-absorbing structure can absorb more collision force, which can further reduce the stress on the reinforced structure.

[0027] In some embodiments, the reinforcement structure and the front fascia structure are shape-adapted.

[0028] In the above technical solution, by adapting the shape of the reinforcing structure and the front bulkhead structure, the reinforcing structure can extend with the front bulkhead structure, which facilitates the installation of the reinforcing structure on the front bulkhead structure, helps to reduce the manufacturing difficulty of the car body, and also enables the reinforcing structure to be reliably fixed to the front bulkhead structure.

[0029] In some embodiments, the front fascia structure is a one-piece molded part.

[0030] In the above technical solution, by constructing the front bulkhead structure as a one-piece molded part, the structural strength of the front bulkhead structure can be further improved. In the event of a frontal collision, the front bulkhead structure can more reliably support the components in the front engine compartment assembly of the vehicle body, further reducing the amount of intrusion of the components in the front engine compartment assembly into the passenger compartment of the vehicle, and further reducing the risk of injury to the occupants in the passenger compartment. Furthermore, since the front bulkhead structure is a one-piece molded part, the number of components that make up the front bulkhead structure is effectively reduced, as is the connection structure between the components that make up the front bulkhead structure. This is conducive to achieving a lightweight design of the front bulkhead structure and also helps to reduce the manufacturing cost of the front bulkhead structure.

[0031] Secondly, embodiments of this application provide a vehicle including the aforementioned vehicle body.

[0052] Unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions.

[0053] Unless otherwise specified, all technical features and optional technical features of this application may be combined to form new technical solutions.

[0054] In this application, "multiple" means two or more (including two).

[0055] The battery device mentioned in the embodiments of this application may include multiple battery cells, which are connected in series, parallel or mixed connection through a busbar component.

[0056] In some embodiments, the battery device includes a housing and a plurality of battery cells housed within the housing.

[0057] As an example, multiple battery cells can be housed in a housing by directly fixing them to the housing.

[0058] As an example, the enclosure may include a first enclosure and a second enclosure. The first enclosure and the second enclosure are fastened together to form a mounting cavity inside the enclosure, which can accommodate multiple battery cells, i.e., multiple battery cells are installed in the mounting cavity. Here, "closed" refers to covering or closing, which can be sealed or not sealed. The first enclosure may be one of the upper enclosure and the lower enclosure, and the second enclosure may be the other of the upper enclosure and the lower enclosure.

[0059] In this embodiment of the application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0060] 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.

[0061] Battery cells can be cylindrical, flat, cuboid, or other shapes, and this application embodiment is not limited to any of these. Battery cells are generally classified into three types according to their packaging method: cylindrical battery cells, square battery cells, and pouch battery cells, and this application embodiment is not limited to any of these types either.

[0062] A battery cell includes a casing, electrode assembly, and electrolyte. The casing houses the electrode assembly and electrolyte. The electrode assembly consists of an anode electrode, a cathode electrode, and a separator. The battery cell primarily functions by the movement of metal ions between the anode and cathode electrodes. The anode electrode includes an anode current collector and an anode active material layer. The anode active material layer is coated on the surface of the anode current collector. The uncoated anode current collector protrudes beyond the coated anode current collector and serves as the anode tab. Taking a lithium-ion battery as an example, the anode current collector can be made of aluminum, and the anode active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide, etc. The cathode electrode includes a cathode current collector and a cathode active material layer. The cathode active material layer is coated on the surface of the cathode current collector. The uncoated cathode current collector protrudes beyond the coated cathode current collector and serves as the cathode tab. The cathode current collector can be made of copper, and the cathode active material can be carbon or silicon, etc. To ensure that a large current can be passed without melting, there are multiple anode tabs stacked together, and there are multiple cathode tabs stacked together.

[0063] The separator can be made of PP (polypropylene) or PE (polyethylene), etc. Furthermore, the electrode assembly can be a wound structure or a stacked structure; the embodiments of this application are not limited to these.

[0064] In recent years, the vehicle industry has developed rapidly. Taking new energy vehicles as an example, the vehicle body, as the core component of the vehicle, plays an irreplaceable and important role.

[0065] In related technologies, the vehicle body includes a front engine compartment assembly, which in turn includes a front bulkhead structure. In the event of a frontal collision, components within the front engine compartment assembly are prone to impacting the front bulkhead structure. Deformation of the front bulkhead structure can cause these components to intrude into the passenger compartment, potentially injuring occupants. Furthermore, in electric vehicles, the battery pack is located below the passenger compartment. In a frontal collision, if components from the front engine compartment assembly intrude into the passenger compartment, they can compress the battery pack, reducing its reliability.

[0066] Based on the above considerations, to address the issues of components within the front engine compartment intruding into the passenger compartment and battery pack compression, a vehicle body was designed after in-depth research. This design includes: a front bulkhead structure extending along the width of the vehicle body; and a reinforcing structure, extending along the length of the vehicle body. At least one side of the front bulkhead structure is provided with a reinforcing structure, which is fixed to the front bulkhead structure and extends along the width of the vehicle body. By fixing the reinforcing structure to the front bulkhead structure, the structural strength of the front bulkhead structure is improved. In the event of a frontal collision, the front bulkhead structure can reliably support the components within the front engine compartment assembly, reducing the amount of intrusion of these components into the passenger compartment and lowering the risk of injury to occupants. Furthermore, when the vehicle is an electric vehicle, it also reduces the risk of battery pack compression, improving the reliability of the battery pack and thus enhancing the overall vehicle reliability.

[0067] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 200 provided in some embodiments of this application. The vehicle 200 can be a gasoline-powered vehicle or a new energy vehicle; a new energy vehicle can be a pure electric vehicle, a hybrid electric vehicle, or a range-extended electric vehicle, etc. A battery device 300 is mounted on the chassis of the vehicle 200. The battery device 300 can be used to power the vehicle 200; for example, the battery device 300 can serve as the operating power source for the vehicle 200. The vehicle 200 may also include a controller 201 and a motor 202. The controller 201 is used to control the battery device 300 to supply power to the motor 202, for example, to meet the power needs of the vehicle 200 during starting, navigation, and driving.

[0068] In some embodiments of this application, the battery device 300 can not only serve as the operating power source for the vehicle 200, but also as the driving power source for the vehicle 200, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 200.

[0069] The following is for reference. Figures 2-5 Describes a vehicle body 100 according to an embodiment of this application.

[0070] like Figure 2 and Figure 3 As shown, the vehicle body 100 according to an embodiment of this application includes: a front bulkhead structure 10, which extends along the width direction of the vehicle body 100; and a reinforcing structure 20, which is provided on at least one side of the front bulkhead structure 10 along the length direction of the vehicle body 100, the reinforcing structure 20 being fixed to the front bulkhead structure 10 and extending along the width direction of the vehicle body 100.

[0071] The vehicle body 100 includes a front engine compartment assembly 30. The front engine compartment assembly 30 includes a front bulkhead structure 10, located in front of the passenger compartment of the vehicle 200. The front engine compartment assembly 30 may also include a front anti-collision beam 32 and two front longitudinal beams 31. The front anti-collision beam 32 extends along the width direction of the vehicle body 100, and the front anti-collision beam 32 and the front bulkhead structure 10 are positioned opposite each other and spaced apart along the length direction of the vehicle body 100. The width direction of the vehicle body 100 is... Figure 2 In the Y direction, the length direction of the vehicle body is 100. Figure 2 In the X direction, the front anti-collision beam 32 can extend in a straight line along the width direction of the vehicle body 100, or the front anti-collision beam 32 can be an arc-shaped structure, extending along the width direction of the vehicle body 100, and protruding in a direction away from the front bulkhead structure 10. Both front longitudinal beams 31 extend along the length direction of the vehicle body 100, and the two front longitudinal beams 31 are arranged opposite each other and spaced apart along the width direction of the vehicle body 100. Along the length direction of the vehicle body 100, the two front longitudinal beams 31 are located between the front anti-collision beam 32 and the front bulkhead structure 10. The rear end of the front longitudinal beam 31 is fixedly connected to the front bulkhead structure 10. An energy-absorbing device 33 can be connected between the front end of the front longitudinal beam 31 and the front anti-collision beam 32. The energy-absorbing device 33 can be an energy-absorbing box, and the energy-absorbing device 33 is fixedly connected to the corresponding front longitudinal beam 31 and the front anti-collision beam 32. When the front of the vehicle body 100 is impacted, the front anti-collision beam 32 can transfer the impact force to the energy absorption device 33. The energy absorption device 33 can absorb the impact force and reduce the risk of deformation of the front longitudinal beam 31, thereby reducing the risk of components in the front engine compartment assembly 30 intruding into the passenger compartment of the vehicle 200. The length direction of the vehicle body 100 is the longitudinal direction of the vehicle body 100, and the width direction of the vehicle body 100 is the lateral direction of the vehicle body 100.

[0072] The front bulkhead structure 10 extends along the width direction of the vehicle body 100. The front bulkhead structure 10 can extend in a straight line along the width direction of the vehicle body 100, or it can be an arc-shaped structure extending along the width direction of the vehicle body 100. The front bulkhead structure 10 protrudes towards the front anti-collision beam 32; in other words, the front bulkhead structure 10 protrudes towards the front side of the vehicle body 100. Along the length direction of the vehicle body 100, at least one side of the front bulkhead structure 10 is provided with a reinforcing structure 20. It should be noted that the reinforcing structure 20 is provided on the front side of the front bulkhead structure 10, or on the rear side of the front bulkhead structure 10, or on both the front and rear sides of the front bulkhead structure 10. The reinforcing structure 20 is fixed to the front bulkhead structure 10. The reinforcing structure 20 can be fixed to the front bulkhead structure 10 by bolts, welded to the front bulkhead structure 10, or snap-fitted to the front bulkhead structure 10. The reinforcing structure 20 extends along the width direction of the vehicle body 100. As an example, the reinforcing structure 20 can extend linearly along the width direction of the vehicle body 100. As another example, the reinforcing structure 20 can be an arc-shaped structure. The reinforcing structure 20 can extend along the width direction of the vehicle body 100 and protrude towards the front anti-collision beam 32. Both ends of the reinforcing structure 20 can extend to the corresponding end positions on the front bulkhead structure 10. The reinforcing structure 20 can be a reinforcing tube beam, a reinforcing rod (solid), etc. The specific construction of the reinforcing structure 20 is not specifically limited, as long as the reinforcing structure 20 can enhance the structural strength of the front bulkhead structure 10. Along the length direction of the vehicle body 100, the orthographic projection of the reinforcing structure 20 and the orthographic projection of the front bulkhead structure 10 have an overlapping area, and the orthographic projection of the reinforcing structure 20 can be located within the orthographic projection range of the front bulkhead structure 10.

[0073] In this application, by fixing the reinforcing structure 20 to the front bulkhead structure 10, the structural strength of the front bulkhead structure 10 is improved, thereby enhancing its impact resistance. In the event of a frontal collision, such as a frontal center pole impact, the front bulkhead structure 10 reliably supports the components within the front engine compartment assembly 30 of the vehicle body 100, reducing the deformation of the front bulkhead structure 10 and minimizing the intrusion of components from the front engine compartment assembly 30 into the passenger compartment of the vehicle 200. This reduces the risk of components from the front engine compartment assembly 30 intruding into the passenger compartment and thus reduces the risk of injury to the occupants. Furthermore, when the vehicle 200 is an electric vehicle, the battery pack 300 is located below the passenger compartment, which also reduces the risk of the battery pack 300 being crushed, improving its reliability and thus enhancing the driving reliability of the vehicle 200.

[0074] In the above technical solution, by fixing the reinforcing structure 20 to the front bulkhead structure 10, the structural strength of the front bulkhead structure 10 is improved. When the vehicle 200 is involved in a frontal collision, the front bulkhead structure 10 can reliably support the components in the front engine compartment assembly 30 of the vehicle body 100, reduce the amount of intrusion of the components in the front engine compartment assembly 30 into the passenger compartment of the vehicle 200, reduce the risk of injury to the occupants in the passenger compartment, and when the vehicle 200 is an electric vehicle, it can also reduce the risk of the battery device 300 being crushed, which is conducive to improving the reliability of the battery device 300 and thus improving the driving reliability of the vehicle 200.

[0075] According to some embodiments of this application, such as Figure 2 and Figure 3 As shown, the front bulkhead structure 10 includes: a front bulkhead middle structure 11 and two front bulkhead end structures 12. The two front bulkhead end structures 12 are opposite to each other and spaced apart along the width direction of the vehicle body 100. The front bulkhead middle structure 11 is connected between the two front bulkhead end structures 12. Along the extension direction of the front bulkhead structure 10, the two ends of the reinforcing structure 20 extend to the corresponding front bulkhead end structures 12 respectively.

[0076] The front bulkhead structure 10 includes a central front bulkhead structure 11 and two end front bulkhead structures 12. The two end front bulkhead structures 12 are arranged opposite each other along the width direction of the vehicle body 100 and are spaced apart along the width direction of the vehicle body 100. The structures of the two end front bulkhead structures 12 can be identical. The central front bulkhead structure 11 is connected between the two end front bulkhead structures 12. Along the extension direction of the front bulkhead structure 10, one end of the central front bulkhead structure 11 is fixedly connected to one end front bulkhead structure 12, and the other end of the central front bulkhead structure 11 is fixedly connected to the other end front bulkhead structure 12. Along the extension direction of the front bulkhead structure 10, both ends of the reinforcing structure 20 extend to the corresponding end front bulkhead structure 12. That is, the left end of the reinforcing structure 20 extends to the left end front bulkhead structure 12, and the right end of the reinforcing structure 20 extends to the right end front bulkhead structure 12.

[0077] It should be noted that, as Figure 2 As shown, the front engine compartment assembly 30 defines an installation space 34, which is used to install components within the front engine compartment assembly 30. The components within the front engine compartment assembly 30 may include structures such as motors. The front bulkhead central structure 11 and the installation space 34 are arranged opposite to each other along the length direction of the vehicle body 100, and the installation space 34 is located on the front side of the front bulkhead central structure 11.

[0078] In the above technical solution, along the extension direction of the front bulkhead structure 10, the two ends of the reinforcing structure 20 extend to the corresponding front bulkhead end structure 12, which enables the reinforcing structure 20 to cover the entire area of ​​the front bulkhead middle structure 11 along the extension direction of the front bulkhead structure 10. This allows the reinforcing structure 20 to correspond with the installation space 34 along the length direction of the vehicle body 100. In the event of a frontal collision of the vehicle 200, this further reduces the amount of intrusion of components in the front engine compartment assembly 30 into the passenger compartment of the vehicle 200, further reducing the risk of injury to the occupants in the passenger compartment. In addition, it also further reduces the risk of the battery device 300 being crushed, which is more conducive to improving the reliability of the battery device 300 and thus further improving the driving reliability of the vehicle 200.

[0079] According to some embodiments of this application, a mounting groove 13 extending along the extension direction of the front bulkhead structure 10 is formed on the side of the front bulkhead structure 10 facing the reinforcing structure 20, and at least a portion of the reinforcing structure 20 is disposed in the mounting groove 13.

[0080] Among them, such as Figure 3 As shown, the mounting groove 13 is formed in the front bulkhead structure 10; in other words, the front bulkhead structure 10 defines the mounting groove 13. Along the length direction of the vehicle body 100, the mounting groove 13 is formed on the side of the front bulkhead structure 10 facing the reinforcing structure 20. The mounting groove 13 extends along the extending direction of the front bulkhead structure 10. When the reinforcing structure 20 is provided on the front side of the front bulkhead structure 10, the mounting groove 13 is formed on the front side of the front bulkhead structure 10. When the reinforcing structure 20 is provided on both the front and rear sides of the front bulkhead structure 10, the mounting groove 13 is formed on both the front and rear sides of the front bulkhead structure 10. The mounting groove 13 is open towards the corresponding reinforcing structure 20. As an example, when the reinforcing structure 20 is provided on the front side of the front bulkhead structure 10, the front end of the mounting groove 13 located on the front side of the front bulkhead structure 10 is open. As another example, when a reinforcing structure 20 is provided on the rear side of the front bulkhead structure 10, the rear end of the mounting groove 13 located on the rear side of the front bulkhead structure 10 is open. At least a portion of the reinforcing structure 20 is disposed within the mounting groove 13, a part of the reinforcing structure 20 is disposed within the mounting groove 13, or the entire structure of the reinforcing structure 20 is disposed within the mounting groove 13. Figure 3 As shown, this application will be described using the example of a reinforcing structure 20 provided on the rear side of the front enclosure structure 10 and an mounting groove 13 formed on the rear side of the front enclosure structure 10.

[0081] In the above technical solution, by having at least a portion of the reinforcing structure 20 disposed within the mounting groove 13, the overall structure of the front bulkhead structure 10 and the reinforcing structure 20 can be made compact, which helps to reduce the overall volume of the front bulkhead structure 10 and the reinforcing structure 20, and reduce the overall assembly space of the front bulkhead structure 10 and the reinforcing structure 20. Furthermore, since the reinforcing structure 20 is disposed within the mounting groove 13, when the reinforcing structure 20 contacts the inner wall surface of the mounting groove 13, the inner wall surface of the mounting groove 13 can limit the reinforcing structure 20, reduce the risk of deformation of the reinforcing structure 20, improve the ability of the reinforcing structure 20 to resist deformation, and further improve the structural strength of the front bulkhead structure 10. In the event of a frontal collision of the vehicle 200, the intrusion of components in the front engine compartment assembly 30 into the passenger compartment of the vehicle 200 is further reduced, further reducing the risk of injury to the occupants in the passenger compartment, and also further reducing the risk of the battery device 300 being crushed, thereby further improving the driving reliability of the vehicle 200.

[0082] According to some embodiments of this application, multiple mounting slots 13 and multiple reinforcing structures 20 are provided, and multiple mounting slots 13 and multiple reinforcing structures 20 are assembled in a one-to-one correspondence.

[0083] One mounting slot 13 houses a reinforcing structure 20. As an example, both the mounting slot 13 and the reinforcing structure 20 are provided as a single unit, with the reinforcing structure 20 positioned within the mounting slot 13. As another example, multiple mounting slots 13 and reinforcing structures 20 are provided, with one reinforcing structure 20 installed within each mounting slot 13. When multiple mounting slots 13 and reinforcing structures 20 are provided, all of them can be located on the front side of the front bulkhead 10, or all of them can be located on the rear side of the front bulkhead 10, or a portion of the mounting slots 13 and a portion of the reinforcing structures 20 can be located on the front side of the front bulkhead 10, while another portion of the mounting slots 13 and another portion of the reinforcing structures 20 can be located on the rear side of the front bulkhead 10.

[0084] In the above technical solution, by assembling the mounting groove 13 and the reinforcing structure 20 in a one-to-one correspondence, the reinforcing structure 20 can be reliably assembled into the corresponding mounting groove 13. The inner wall surface of the mounting groove 13 can reliably limit the corresponding reinforcing structure 20, further reducing the risk of deformation of the reinforcing structure 20, further improving the ability of the reinforcing structure 20 to resist deformation, and further improving the structural strength of the front structure 10.

[0085] According to some embodiments of this application, the reinforcing structure 20 is fixedly provided with a mounting sleeve 21, which has a mounting hole. Fasteners are inserted through the mounting hole and connected to the front structure 10 so that the reinforcing structure 20 is fixed to the front structure 10.

[0086] Among them, such as Figure 3and Figure 4 As shown, the reinforcing structure 20 is fixedly provided with a mounting sleeve 21. The mounting sleeve 21 can be welded to the reinforcing structure 20, or it can be snapped onto the reinforcing structure 20. The specific assembly method of the mounting sleeve 21 and the reinforcing structure 20 is not specifically limited, as long as the mounting sleeve 21 is fixed to the reinforcing structure 20. As an example, the fastener can be a bolt, and the front cover structure 10 can have a threaded hole corresponding to the mounting hole. The fastener passes through the mounting hole and is assembled in the threaded hole of the front cover structure 10, thereby fixing the fastener to the front cover structure 10, and thus fixing the reinforcing structure 20 to the front cover structure 10. As another example, the front cover structure 10 can have a snap-fit ​​part corresponding to the mounting hole. The fastener passes through the mounting hole, and the fastener and the snap-fit ​​part snap-fit ​​together, thereby fixing the fastener to the front cover structure 10, and thus fixing the reinforcing structure 20 to the front cover structure 10.

[0087] In the above technical solution, by fixing the mounting sleeve 21 to the reinforcing structure 20, and fasteners passing through the mounting holes and connected to the front bulkhead structure 10, the reinforcing structure 20 can be reliably fixed to the front bulkhead structure 10, thereby making the reinforcing structure 20 and the front bulkhead structure 10 form a whole. When the vehicle 200 is involved in a frontal collision, the front bulkhead structure 10 can effectively resist the impact of the components inside the front engine compartment assembly 30.

[0088] According to some embodiments of this application, such as Figure 3 and Figure 4 As shown, there are multiple mounting sleeves 21, which are arranged along the extension direction of the reinforcing structure 20.

[0089] The mounting sleeves 21 can be multiple, such as two, three, four, or five. The number of mounting sleeves 21 can be reasonably selected according to the actual situation. This application uses thirteen mounting sleeves 21 as an example for explanation. The multiple mounting sleeves 21 are arranged along the extension direction of the reinforcing structure 20. The multiple mounting sleeves 21 can be arranged sequentially with intervals along the extension direction of the reinforcing structure 20, or they can be arranged evenly along the extension direction of the reinforcing structure 20. The interval between any two adjacent mounting sleeves 21 along the extension direction of the reinforcing structure 20 is the same. Multiple fasteners are used, and the multiple mounting sleeves 21 and multiple fasteners are assembled in a one-to-one correspondence.

[0090] In the above technical solution, by setting multiple mounting sleeves 21, multiple fasteners can be used simultaneously to reliably fix the reinforcing structure 20 to the front bulkhead structure 10, thereby improving the connection strength between the reinforcing structure 20 and the front bulkhead structure 10, reducing the risk of separation between the reinforcing structure 20 and the front bulkhead structure 10, and thus improving the reliability of the vehicle body 100.

[0091] According to some embodiments of this application, such as Figure 3 and Figure 4 As shown, the reinforcing structure 20 is constructed as a reinforcing beam.

[0092] The reinforcing structure 20 is constructed as a reinforcing beam, which is a strip structure extending along the extension direction of the front structure 10. The reinforcing beam can be a solid structure or a hollow structure to reduce the weight of the reinforcing structure 20. The cross-sectional shape of the reinforcing beam can be circular, polygonal, or other shapes, and the cross-sectional shape can be reasonably selected and set according to the actual use. This application uses a square cross-sectional shape of the reinforcing beam as an example for illustration.

[0093] In the above technical solution, by constructing the reinforcing structure 20 as a reinforcing beam, the structure of the reinforcing structure 20 can be simplified, making it easier to manufacture and improve the production efficiency of the reinforcing structure 20, thereby improving the production efficiency of the body 100. Furthermore, due to the simplicity of the structure of the reinforcing structure 20, labor input costs can be saved, thereby reducing the manufacturing cost of the body 100.

[0094] According to some embodiments of this application, the reinforcing structure 20 has a buffer space 23.

[0095] The reinforcing structure 20 includes a buffer space 23. As an example, the buffer space 23 may comprise a single space. As another example, the buffer space 23 may comprise multiple subspaces arranged sequentially along the extending direction of the reinforcing structure 20. Figure 3 As shown, the buffer space 23 can extend along the extension direction of the reinforcing structure 20, and the buffer space 23 can penetrate the reinforcing structure 20 along the extension direction of the reinforcing structure 20. The reinforcing structure 20 can be a tubular structure, and the tubular reinforcing structure 20 defines the buffer space 23.

[0096] In the above technical solution, the reinforcement structure 20 forms a buffer space 23. On the basis of improving the structural strength of the front structure 10, when the reinforcement structure 20 is squeezed, it is conducive to the deformation and energy absorption of the reinforcement structure 20, reducing the risk of stress concentration in the reinforcement structure 20, thereby reducing the risk of fracture of the reinforcement structure 20. Furthermore, when the reinforcement structure 20 is impacted, it is conducive to the reinforcement structure 20 to transmit force in multiple directions.

[0097] According to some embodiments of this application, the vehicle body 100 further includes an energy-absorbing structure (not shown in the figure), and the energy-absorbing structure is provided in the buffer space 23.

[0098] The energy-absorbing structure is deformable and can be fixed to the reinforcing structure 20. The energy-absorbing structure can be fixed to the reinforcing structure 20 by adhesive bonding, welding, or bolts. The specific method of fixing the energy-absorbing structure to the reinforcing structure 20 is not limited, as long as the energy-absorbing structure is fixed to the reinforcing structure 20. The energy-absorbing structure can be constructed of rubber, etc.

[0099] In the above technical solution, by setting the energy-absorbing structure in the buffer space 23, when the reinforcing structure 20 is compressed, the energy-absorbing structure can absorb energy, further reducing the risk of stress concentration in the reinforcing structure 20, thereby further reducing the risk of fracture of the reinforcing structure 20.

[0100] According to some embodiments of this application, the energy-absorbing structure includes at least one of an energy-absorbing box, a buffer frame, a spring, and an airbag component.

[0101] The energy-absorbing structure may include at least one of the following: an energy-absorbing box, a buffer frame, a spring, and an airbag component. That is, the energy-absorbing structure may include one of the following: an energy-absorbing box, a buffer frame, a spring, and an airbag component; or the energy-absorbing structure may include any two of the following: an energy-absorbing box, a buffer frame, a spring, and an airbag component; or the energy-absorbing structure may include any three of the following: an energy-absorbing box, a buffer frame, a spring, and an airbag component; or the energy-absorbing structure may include any four of the following: an energy-absorbing box, a buffer frame, a spring, and an airbag component.

[0102] According to some embodiments of this application, the energy-absorbing box can have hollow cavities, and there can be multiple hollow cavities. These hollow cavities can be parallel to each other, and the cross-sectional shape of the hollow cavities can be square, rectangular, circular, rhomboid, polygonal, etc. The energy-absorbing box material can be made of high-ductility aluminum alloy. The cross-sectional shape of the hollow cavity can be square. The cross-sectional shape of the hollow cavity can also be rectangular. The cross-sectional shape of the hollow cavity can also be circular. The cross-sectional shape of the hollow cavity can also be regular hexagonal. Alternatively, at least some of the hollow cavities can have a rhomboid cross-sectional shape.

[0103] According to some embodiments of this application, a buffer frame encloses and forms a buffer cavity. The buffer cavity is formed by the buffer frame; in other words, the buffer frame defines the buffer cavity. As an example, the buffer cavity may be located inside the buffer frame. As another example, the buffer cavity has at least one open end. The buffer frame may be a separately configured frame structure.

[0104] According to some embodiments of this application, the energy-absorbing structure is constructed as an airbag component. As an example, the airbag component is similar to the airbag on vehicle 200. Initially, the airbag component is not filled with gas, which will not be described in detail here. As another example, the airbag component is a bag filled with gas.

[0105] In the above technical solution, by including at least one of the energy-absorbing structure, energy-absorbing box, buffer frame, spring, and airbag component, the energy-absorbing structure can have energy-absorbing performance, thereby meeting the working requirements and improving the energy-absorbing effect of the energy-absorbing structure. After being impacted, the energy-absorbing structure can absorb more collision force, which can further reduce the force on the reinforcing structure 20.

[0106] According to some embodiments of this application, the reinforcing structure 20 and the front bulkhead structure 10 are shape-adapted.

[0107] Wherein, along the extending direction of the reinforcing structure 20 and along the extending direction of the front structure 10, the shape of the reinforcing structure 20 is the same as or approximately the same as the shape of the front structure 10, and the extending direction of the reinforcing structure 20 is the same as or approximately the same as the extending direction of the front structure 10.

[0108] In the above technical solution, by adapting the shapes of the reinforcing structure 20 and the front bulkhead structure 10, the reinforcing structure 20 can extend with the front bulkhead structure 10, which makes it easier to install the reinforcing structure 20 on the front bulkhead structure 10, which helps to reduce the manufacturing difficulty of the body 100, and also enables the reinforcing structure 20 to be reliably fixed to the front bulkhead structure 10.

[0109] According to some embodiments of this application, the front structure 10 is a one-piece molded part.

[0110] The front bulkhead structure 10 is constructed as a single molded part. This design can further enhance the structural strength of the front bulkhead structure 10. In the event of a frontal collision, the front bulkhead structure 10 can more reliably support the components in the front engine compartment assembly 30 of the vehicle body 100, further reducing the intrusion of the components in the front engine compartment assembly 30 into the passenger compartment of the vehicle 200, and further reducing the risk of injury to the occupants in the passenger compartment. Furthermore, since the front bulkhead structure 10 is a single molded part, the number of components that make up the front bulkhead structure 10 is effectively reduced, as are the connecting structures between the components. This is conducive to achieving a lightweight design of the front bulkhead structure 10 and also helps to reduce the manufacturing cost of the front bulkhead structure 10.

[0111] According to some embodiments of this application, such as Figure 2 and Figure 3As shown, along the length of the vehicle body 100, at least one side of the front bulkhead structure 10 has a reinforcing rib structure 14, which is more conducive to improving the structural strength of the front bulkhead structure 10. When the vehicle 200 is involved in a frontal collision, the front bulkhead structure 10 can more reliably support the components in the front engine compartment assembly 30 of the vehicle body 100, further reducing the amount of intrusion of the components in the front engine compartment assembly 30 into the passenger compartment of the vehicle 200, further reducing the risk of injury to the occupants in the passenger compartment. In addition, when the vehicle 200 is an electric vehicle, it can also further reduce the risk of the battery device 300 being crushed, which is more conducive to improving the reliability of the battery device 300 and thus further improving the driving reliability of the vehicle 200.

[0112] It should be noted that the reinforcing structure 20 can be constructed as a metal part, and the reinforcing structure 20 can be made of materials such as aluminum and steel. The reinforcing structure 20 can be formed by extruding aluminum profiles or by rolling steel.

[0113] like Figure 1 As shown, the vehicle 200 according to an embodiment of this application includes the body 100 of this application embodiment.

[0114] The body 100 is mounted on the vehicle 200 and can be mounted on the chassis of the vehicle 200. In the event of a frontal collision, the front bulkhead structure 10 can reliably support the components in the front engine compartment assembly 30 of the body 100, reduce the intrusion of the components in the front engine compartment assembly 30 into the passenger compartment of the vehicle 200, reduce the risk of injury to the occupants in the passenger compartment, and when the vehicle 200 is an electric vehicle, it can also reduce the risk of the battery device 300 being crushed, which is conducive to improving the reliability of the battery device 300 and thus improving the driving reliability of the vehicle 200.

[0115] According to some embodiments of this application, see Figure 2 and Figure 3As shown, this application provides a vehicle body 100, including a front bulkhead structure 10 and a reinforcing structure 20, both of which can be made of metal. The front bulkhead structure 10 extends along the width direction of the vehicle body 100, and the reinforcing structure 20 is provided on at least one side of the front bulkhead structure 10 along the length direction of the vehicle body 100. The reinforcing structure 20 is fixed to the front bulkhead structure 10 and extends along the width direction of the vehicle body 100. The front bulkhead structure 10 includes a front bulkhead middle structure 11 and two front bulkhead end structures 12. The two front bulkhead end structures 12 are opposite to and spaced apart along the width direction of the vehicle body 100. The front bulkhead middle structure 11 is connected between the two front bulkhead end structures 12. Along the extension direction of the front bulkhead structure 10, both ends of the reinforcing structure 20 extend to the corresponding front bulkhead end structures 12. A mounting groove 13 extending along the extension direction of the front bulkhead structure 10 is formed on the side of the front bulkhead structure 10 facing the reinforcing structure 20, and at least a portion of the reinforcing structure 20 is disposed within the mounting groove 13. The mounting slots 13 and the reinforcing structure 20 are assembled in a one-to-one correspondence. The reinforcing structure 20 is fixedly provided with a mounting sleeve 21, which has a mounting hole. Fasteners are inserted through the mounting hole and connected to the front bulkhead structure 10 to fix the reinforcing structure 20 to the front bulkhead structure 10. The reinforcing structure 20 is constructed as a reinforcing beam, and the reinforcing beam forms a buffer space 23.
