[0056] This application provides a vehicle. The vehicle can be a pure electric vehicle, a hybrid electric vehicle, a plug-in hybrid electric vehicle, a range-extended electric vehicle, a gasoline vehicle, etc.

[0057] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 100 provided in an embodiment of this application. The vehicle 100 includes a body assembly 10. The body assembly 10 is the frame of the vehicle, used to support the load on the vehicle 100. The body assembly 10 is also used to install various electrical and mechanical equipment to enable the vehicle 100 to have driving functions and various driver assistance functions.

[0058] The body assembly 10 serves two purposes: firstly, it forms a cavity that accommodates the engine and its components; secondly, when the vehicle 100 is involved in a collision, the various components of the body assembly 10 work together to absorb and transfer the energy generated by the collision, thereby reducing the energy transferred to the passenger compartment.

[0059] In some embodiments, please refer to Figure 2 , Figure 2This is a schematic diagram of the vehicle body assembly 10 provided in an embodiment of this application. The vehicle body assembly 10 includes a central tunnel structure 2. The central tunnel structure 2 connects the main body structure 1 of the vehicle 100 and the floor of the vehicle 100 (specifically, located below the passenger compartment). The main body structure 1 of the vehicle is the front end of the vehicle, such as the front engine compartment structure, the body frame supporting the front engine compartment structure, etc. The specific structure of the main body structure 1 will be described in detail later.

[0060] When vehicle 100 is involved in a collision, the main structure 1 usually collides with the obstacle. The collision energy is transferred through the main structure 1 to the central tunnel structure 2, and then to the floor of vehicle 100, causing damage to the floor of vehicle 100 and resulting in deformation of the passenger compartment, which can easily threaten the safety of the driver and passengers.

[0061] Based on this, please continue reading Figure 2 The central passage structure 2 includes a first enclosure 21 and a first reinforcing member 22. The first enclosure 21 encloses a first space; the first reinforcing member 22 is disposed in the first space and connected to the first enclosure 21.

[0062] By connecting the first reinforcement member 22 to the first bulkhead 21, the structural strength of the first bulkhead 21 can be strengthened, thereby strengthening the structural strength of the central tunnel structure 2 and enhancing its impact resistance. In this way, when the vehicle assembly 10 is subjected to a collision, the energy of the collision is transferred to the central tunnel structure 2, which will not deform or will only undergo minimal deformation, thus preventing deformation of the vehicle assembly 10 and consequently preventing deformation of the passenger compartment, protecting the safety of the occupants inside.

[0063] The first enclosure 21 can be arranged around a first direction to form a first space. The first direction is the length direction of the vehicle 100.

[0064] For example, the first enclosure 21 may be arranged around the first direction to form a passage that runs through the first direction, forming a first space.

[0065] For example, the first enclosure 21 may also be less than one circumference around the first direction. For instance, the first enclosure 21 may include a first panel, a second panel, and a third panel. The first panel, the second panel, and the third panel are connected sequentially around the first direction to form the first enclosure 21.

[0066] The first reinforcing member 22 can be a rod-shaped structure, a block-shaped structure, or a plate-shaped structure. This application uses a plate-shaped structure as an example for illustration.

[0067] In some embodiments, the first reinforcing member 22 includes a first reinforcing plate 23.

[0068] The first reinforcing plate 23 has a larger contact area with the first enclosure plate 21, providing better support for the first enclosure plate 21 and thus strengthening its structural strength. Furthermore, the first reinforcing plate 23 is easier to connect to the first enclosure plate 21.

[0069] In some embodiments, please refer to Figure 3 , Figure 3 for Figure 2 A schematic diagram of the structure of the first reinforcing plate. The first reinforcing plate 23 includes a first body portion 231 and a first protrusion portion 232. The first body portion 231 is connected to the first surrounding plate 21. The first protrusion portion 232 is provided on the first body portion 231 and protrudes along the thickness direction of the first reinforcing plate 23.

[0070] By providing the first protrusion 232, the structural strength of the first body part 231 can be enhanced, thereby increasing the structural strength of the first enclosure 21.

[0071] In this case, along the thickness direction of the first reinforcing plate 23, the first protrusion 232 can be located above the first body portion 231, or the first protrusion 232 can be located below the first body portion 231.

[0072] In some embodiments, please continue reading Figure 2 The vehicle body assembly 10 also includes a main structure 1, a central tunnel structure 2 connected to the main structure 1 and adapted to connect to the floor of the vehicle 100.

[0073] By setting up the central tunnel structure 2, the main structure 1 is connected to the floor of the vehicle 100. When the vehicle 100 collides, the collision energy transmitted to the main structure 1 can be transmitted to the floor of the vehicle 100 through the central tunnel structure 2, thereby avoiding the deformation of the passenger compartment caused by the collision and protecting the safety of the occupants in the passenger compartment.

[0074] In some embodiments, please continue reading Figure 3 The first reinforcing member 22 includes a first reinforcing plate 23, and a first connecting portion 233 is formed at one end of the first reinforcing plate 23 facing away from the main structure 1. The first connecting portion 233 is adapted to connect to the floor.

[0075] The first connecting part 233 of the first reinforcing plate 23 is connected to the floor. When the energy of the collision is transferred to the main structure 1, it can be transferred to the floor through the first reinforcing plate 23.

[0076] In some embodiments, the first reinforcing plate 23 further includes a second protrusion 234, which is disposed at one end of the first body portion 231 opposite to the main body structure 1 and protrudes along the thickness direction of the first reinforcing plate 23. The second protrusion 234 is formed as a first connecting portion 233.

[0077] The placement of the second protrusion 234 at the end furthest from the first protrusion 232 further increases the structural strength of the first reinforcing plate 23. Furthermore, the second protrusion 234 forms the first connecting portion 233 and connects to the floor, thereby strengthening the connection between the first reinforcing plate 23 and the floor.

[0078] Along the thickness direction of the first reinforcing plate 23, the second protrusion 234 and the first protrusion 232 can be located on one side of the first body portion 231, or on both sides of the first body portion 231.

[0079] In some embodiments, the first reinforcing plate 23 is provided with a first recess 235, which is recessed along the surface of the first body portion 231 opposite to the second protrusion 234 to the second protrusion 234.

[0080] By recessing the first recess 235 into the second protrusion 234, the material of the first reinforcing plate 23 can be saved, thereby reducing the weight of the first reinforcing plate 23. This not only saves production costs but also improves the driving performance of the vehicle 100.

[0081] In some embodiments, the first protrusion 232 is provided at one end of the first body portion 231 facing the main structure 1, and the protrusion direction of the first protrusion 232 is opposite to the protrusion direction of the second protrusion 234.

[0082] The first protrusion 232 and the second protrusion 234 are located at both ends of the first body portion 231 and along the thickness direction of the first reinforcing plate 23. The first protrusion 232 and the second protrusion 234 are located on both sides of the first body portion 231, which can jointly strengthen the structural strength of the first body portion 231, thereby strengthening the structural strength of the first reinforcing plate 23.

[0083] In some embodiments, the first reinforcing plate 23 further includes a first bending portion 236 and a second bending portion 237, both of which are connected to the first body portion and are disposed opposite to each other along a second direction, the second direction being perpendicular to the first direction; the first bending portion 236 and the second bending portion 237 are bent along the direction of the first body portion away from the first protrusion 232.

[0084] The first bending portion 236 and the second bending portion 237 can provide support on both sides of the first protrusion 232, the first body portion and the second protrusion 234, thereby increasing the structural strength of the first protrusion 232, the first body portion and the second protrusion 234, and thus increasing the structural strength of the first reinforcing plate 23.

[0085] The first reinforcing plate 23 is also provided with mounting holes, clearance holes, and leakage holes. The mounting holes are used for components to pass through and connect to the first enclosure plate 21. The clearance holes are used to allow some components on the first enclosure plate 21 to pass through. The leakage holes are used to prevent electrophoretic fluid from remaining between the first enclosure plate 21 and the first reinforcing plate 23 after electrophoresis.

[0086] In some embodiments, please continue reading Figure 2 The central passage structure 2 also includes a central passage front connecting plate 24, one end of which is connected to the main structure 1, and the other end of which is connected to the first enclosure plate 21.

[0087] By setting the front connecting plate 24 of the central channel, the main structure 1 and the central channel structure 2 are connected, so that the collision energy transmitted to the main structure 1 can be transmitted to the central channel structure 2 and then further transmitted through the central channel structure 2, thereby preventing the main structure 1 from deforming and preventing the passenger compartment from deforming, thus protecting the occupants in the passenger compartment.

[0088] In some embodiments, the central access front connecting plate 24 includes at least one of a first hot-dip galvanized steel plate and a first aluminized steel plate.

[0089] The central passage front connecting plate 24 can be a first hot-dip galvanized steel plate, a first aluminized zinc steel plate, or a combination of a first hot-dip galvanized steel plate and a first aluminized steel plate.

[0090] In some embodiments, please refer to Figure 4 , Figure 4 This is a structural schematic diagram of the vehicle body assembly provided in an embodiment of this application from another perspective. The main structure 1 includes a support plate 11, a crash beam 12, and a connecting assembly 13. The central channel structure 2 is connected to the support plate 11. The crash beam 12 is located on the side of the support plate 11 opposite to the central channel structure 2. The connecting assembly 13 is connected between the support plate 11 and the crash beam 12.

[0091] The anti-collision beam 12 is connected to the connecting assembly 13, the connecting assembly 13 is connected to the support plate 11, and the support plate 11 is connected to the central tunnel structure 2, forming a collision energy transfer structure. When the vehicle 100 collides, the energy generated by the collision can be transferred to the floor through the anti-collision beam 12, the connecting assembly 13, the support plate 11, and the central tunnel structure 2, thereby reducing the impact of the collision on the passenger compartment, preventing the passenger compartment from deforming or causing only minor deformation, and thus protecting the safety of the occupants inside the passenger compartment.

[0092] The connecting component 13 can be one, two, or more than two.

[0093] In some embodiments, please refer to Figure 5 , Figure 5 for Figure 4 A schematic diagram of the structure of the middle support plate. The support plate 11 includes at least one of a second hot-dip galvanized steel plate and a second aluminized steel plate.

[0094] The support plate 11 can be a second hot-dip galvanized steel plate, a second aluminized steel plate, or a second hot-dip galvanized steel plate and a second aluminized steel plate.

[0095] In some embodiments, the support plate 11 includes a first sub-plate 111 and a second sub-plate 112. Along the height direction of the vehicle 100, the second sub-plate 112 is connected to the lower end of the first sub-plate 111. The second sub-plate 112 includes at least one of a second hot-dip galvanized steel plate and a second aluminized steel plate.

[0096] The second sub-plate 112 can be a second hot-dip galvanized steel plate, a second aluminized steel plate, or a second hot-dip galvanized steel plate and a second aluminized steel plate.

[0097] In some embodiments, please refer to Figure 6 , Figure 6 for Figure 2 The diagram shows the structure of the second connecting plate. The body assembly 10 also includes a second connecting plate 15, which is connected to the second sub-plate 112 and is adapted to connect to the A-pillar of the vehicle.

[0098] By setting the second connecting plate 15, the second sub-plate 112 and the A-pillar of the vehicle 100 are connected, so that the second sub-plate 112, the second connecting plate 15 and the A-pillar form a force transmission path. When the vehicle 100 collides, the collision energy is transferred to the second sub-plate 112, and can be transferred to the body assembly 10 through the second connecting plate 15 and the A-pillar, thereby reducing the collision energy transferred from the second sub-plate 112 to the passenger compartment.

[0099] In some embodiments, the second connecting plate 15 includes at least one of a third hot-dip galvanized steel plate and a third aluminized steel plate.

[0100] The second connecting plate 15 can be a third hot-dip galvanized steel plate, a third aluminized steel plate, or both a third galvanized steel plate and a third aluminized steel plate.

[0101] In some embodiments, the main structure 1 further includes an energy-absorbing component 14, which includes a plurality of energy-absorbing boxes 141 arranged along a second direction, the second direction being perpendicular to the first direction.

[0102] When vehicle 100 collides with an obstacle, the main structure 1 collides with the obstacle, and the energy-absorbing component 14 of the main structure 1 can absorb the collision energy. The energy-absorbing component 14 includes multiple energy-absorbing boxes 141, which can absorb more collision energy to reduce the collision energy transmitted from the energy-absorbing boxes 141 and reduce the damage to vehicle 100.

[0103] The number of multiple energy-absorbing boxes 141 can be 2, 3, 4, 5, 6, 7, 8, 9, etc.

[0104] In some examples, the energy-absorbing component 14 is located between the connecting component 13 and the anti-collision beam 12.

[0105] The energy-absorbing component 14 can support the anti-collision beam 12 on the one hand, and absorb the energy transmitted from the anti-collision beam 12 to the connecting component 13 on the other hand, so as to reduce the damage to the connecting component 13.

[0106] In some embodiments, the main structure 1 further includes a support plate 11, a central channel structure 2 connected to the support plate 11, and a connecting component 13 including a longitudinal beam 131 and a wheel cover structure 132. The longitudinal beam 131 is connected to the support plate 11; one end of the wheel cover structure 132 is connected to the longitudinal beam 131, and the other end of the wheel cover structure 132 is connected to the support plate 11.

[0107] The longitudinal beam 131 and the support plate 11 are connected by the wheel arch structure 132, so that the longitudinal beam 131, the wheel arch structure 132 and the support plate 11 form a triangular structure. When collision energy is transferred from the anti-collision beam 12, the longitudinal beam 131, the wheel arch structure 132 and the support plate 11 can form a good support structure, reducing the impact of collision energy.

[0108] In some embodiments, please continue reading Figure 4 The main structure 1 also includes a crash beam 12, which is located on the side of the support plate 11 facing away from the central channel structure 2; the multiple energy-absorbing boxes 141 include a first energy-absorbing box 141a and a second energy-absorbing box 141b, the first energy-absorbing box 141a is connected between the crash beam 12 and the longitudinal beam 131; the second energy-absorbing box 141b is connected between the crash beam 12 and the wheel cover structure 132.

[0109] The first energy-absorbing box 141a and the second energy-absorbing box 141b can absorb more energy transmitted from the anti-collision beam 12. After absorbing all the energy, the first energy-absorbing box 141a transfers the remaining collision energy to the longitudinal beam 131, and the second energy-absorbing box 141b transfers the remaining collision energy to the wheel arch structure 132, thereby reducing the collision energy transmitted from the anti-collision beam 12 to the longitudinal beam 131 and the wheel arch structure 132. This protects the longitudinal beam 131 from damage caused by receiving too much collision energy transmitted from the anti-collision beam 12.

[0110] The first energy-absorbing box 141a can be a single unit. Alternatively, there can be multiple first energy-absorbing boxes 141a. For example, the number of multiple first energy-absorbing boxes 141a can be 2, 3, 4, 5, 6, 7, 8, or 9. The second energy-absorbing box 141b can be a single unit. Alternatively, there can be multiple second energy-absorbing boxes 141b. For example, the number of multiple second energy-absorbing boxes 141b can be 2, 3, 4, 5, 6, 7, 8, or 9.

[0111] In some embodiments, the energy-absorbing box 141 is provided with a second recess 141c, which is recessed from the outer surface of the energy-absorbing box 141 toward the inner cavity of the energy-absorbing box 141.

[0112] By providing the second recess 141c of the energy-absorbing box 141, when impact energy is transferred to the energy-absorbing box 141, the second recess 141c can guide the energy-absorbing box 141 to form a crush, thereby absorbing the impact energy and reducing the impact energy transferred from the energy-absorbing box 141.

[0113] There can be one second recess 141c. There can also be multiple second recesses 141c. For example, the number of multiple second recesses 141c can be 2, 3, 4, 5, 6, 7, 8, 9, etc.

[0114] In some embodiments, the inner surface of the energy-absorbing box 141 is provided with a third protrusion 141d; the second recess 141c extends to the third protrusion 141d.

[0115] The third protrusion 141d can strengthen the structural strength of the energy-absorbing box 141, thereby enabling the energy-absorbing box 141 to absorb more collision energy and reduce the collision energy transmitted from the energy-absorbing box 141.

[0116] There can be one third protrusion 141d. There can also be multiple third protrusions 141d. For example, the number of multiple third protrusions 141d can be 2, 3, 4, 5, 6, 7, 8, 9, etc.

[0117] In some embodiments, the energy-absorbing box 141 includes a first box body 142 and a second box body 143 that are separately disposed, and the first box body 142 and the second box body 143 are joined together to form the inner cavity of the energy-absorbing box 141.

[0118] The separation of the first box 142 and the second box 143 can reduce the processing difficulty of the energy-absorbing box 141 and facilitate the processing of the second recess 141c on the outer surface of the first box 142 and the second box 143, and the processing of the third protrusion 141d on the inner surface of the first box 142 and the second box 143, so that the energy-absorbing box 141 can better absorb the energy of the collision.

[0119] In some embodiments, please refer to Figure 7 and combined Figure 8 and Figure 4 The main structure 1 includes a connecting component 13, which includes a longitudinal beam 131. The longitudinal beam 131 connects the energy-absorbing component 14 and the support plate 11. The longitudinal beam 131 includes a beam body 131a and a second reinforcing member 131b. The beam body 131a has a cavity. The second reinforcing member 131b is located in the cavity and is connected to the beam body 131a.

[0120] in, Figure 7 for Figure 4 Schematic diagram of the middle longitudinal beam. Figure 8 for Figure 7 A structural diagram of the central longitudinal beam without the connecting plate.

[0121] When the vehicle 100 collides, the collision energy is transferred to the longitudinal beam 131 of the connecting assembly 13, and is connected to the beam 131a through the second reinforcing member 131b, increasing the cross-sectional area of ​​the beam 131a, thereby increasing the structural strength of the beam 131a, and further increasing the structural strength of the longitudinal beam 131, thus enhancing the anti-collision performance of the longitudinal beam 131.

[0122] Furthermore, when the collision energy transmitted to the longitudinal beam 131 is too large, the second reinforcing plate 131c increases the cross-sectional area of ​​the beam 131a, allowing the longitudinal beam 131 to collapse along the direction of its extension and absorb the collision energy. The cavity also provides space for the collapse of the longitudinal beam 131, preventing the longitudinal beam 131 from bending in the second direction and losing its function of absorbing collision energy.

[0123] The second reinforcing member 131b can be a rod-shaped structure, a block-shaped structure, or a plate-shaped structure. This application uses a plate-shaped structure as an example for illustration.

[0124] In some embodiments, the second reinforcing member 131b includes a second reinforcing plate 131c.

[0125] The second reinforcing plate 131c can have a larger contact area with the beam 131a, providing better support for the beam 131a and thus strengthening the structural strength of the beam 131a. Furthermore, the second reinforcing plate 131c is easier to connect to the beam 131a.

[0126] In some embodiments, the beam 131a includes a second enclosure plate 131d and a sealing plate 131e. The second enclosure plate 131d is arranged around the extension direction of the longitudinal beam 131 to form a second space. One end of the second space has a second opening in the second direction. The sealing plate 131e is connected to the second enclosure plate 131d and covers the second opening. The second reinforcing plate 131c is connected to the sealing plate 131e.

[0127] After the second reinforcing plate 131c is connected to the sealing plate 131e, the sealing plate 131e covers the opening of the second enclosure plate 131d to form a beam 131a. This facilitates the installation of the second reinforcing plate 131c.

[0128] For example, the second enclosure 131d may include a fourth plate, a fifth plate, and a sixth plate. The fourth plate, the fifth plate, and the sixth plate are connected sequentially around the longitudinal beam 131 to form the second enclosure 131d.

[0129] The material of the second enclosure 131d can be hot-dip galvanized steel sheet or aluminized steel sheet.

[0130] The material of the sealing plate 131e can be hot-dip galvanized steel sheet or aluminized steel sheet.

[0131] In some embodiments, beam 131a includes at least one of hot-dip galvanized steel beam and aluminized steel beam.

[0132] The beam 131a can be a galvanized steel beam, an aluminized steel beam, or a hot-dip galvanized steel beam and an aluminized steel beam.

[0133] In some embodiments, the second reinforcing plate 131c includes a second main body portion 131f and a fourth protrusion portion 131g. The second main body portion 131f is connected to the sealing plate 131e. The fourth protrusion portion 131g is disposed on the second main body portion 131f and protrudes in the direction opposite to the sealing plate 131e.

[0134] The fourth protrusion 131g can increase the structural strength of the second main body 131f, thereby increasing the structural strength of the sealing plate 131e and enhancing the anti-collision performance of the sealing plate 131e.

[0135] In some embodiments, the second reinforcing plate 131c is further provided with a third recess 131h, which is recessed from the side surface of the second main body portion 131f toward the sealing plate 131e to the fourth protrusion 131g.

[0136] The third recessed portion 131h is recessed to the fourth protruding portion 131g, which can save material of the second reinforcing plate 131c, thereby reducing the weight of the second reinforcing plate 131c. This can save production costs while improving the driving performance of the vehicle 100.

[0137] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
