Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0034] It should be understood that the terms such as "have", "contain" and "include" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0035] In the description of the present application, it should be further explained that, unless otherwise explicitly specified and limited, the terms "mount", "connect", and "connect" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] According to the first aspect of the present application, referring to Figure 1 The present disclosure provides a front floor assembly, comprising a floor 1, a coaming assembly 2, and a reinforcing assembly 3.

[0037] In the present embodiment, the floor 1 and the coaming assembly 2 are connected to each other. The reinforcing assembly 3 is connected to the floor 1 and the coaming assembly 2, and can improve the connection strength between the floor 1 and the coaming assembly 2.

[0038] In some embodiments, the surrounding plate assembly 2 comprises a surrounding plate 21 and a torsion box 22 connected to the floor 1 and the surrounding plate 21.

[0039] In the embodiment, the torsion box 22 is made of aluminum alloy material by casting, which is simple in process, high in strength and light in weight. The floor 1 and the surrounding plate 21 are made of a metal material different from the torsion box 22, for example, can be sheet metal parts.

[0040] In some embodiments, referring to Figure 2 The reinforcing assembly 3 comprises a reinforcing part 31 connected to the floor 1.

[0041] In the embodiment, the reinforcing part 31 can be directly connected to the floor 1, for example, by welding or bolt connection. The reinforcing part 31 can also be indirectly connected to the floor 1, for example, through the first reinforcing seat 32 and / or the second reinforcing seat 33.

[0042] In some embodiments, the reinforcing part 31 comprises a first reinforcing portion 311 connected to the side of the torsion box 22 facing the floor 1.

[0043] In the embodiment, after the reinforcing part 31 is connected to the floor 1, the first reinforcing portion 311 is connected to the torsion box 22, which can improve the connection strength between the torsion box 22 and the floor 1, so that the connection between the torsion box 22 and the floor 1 is not easy to separate when the vehicle collides, and the safety performance of the vehicle is improved.

[0044] In the embodiment, on the basis of the connection (for example, riveting) of the torsion box 22 and the floor 1, the first reinforcing portion 311 supporting the torsion box 22 is added, which improves the connection reliability between the torsion box 22 and the floor 1 while ensuring the stability of the vehicle body. Therefore, when the vehicle suffers a frontal collision or an offset collision, the transmission of the collision load becomes smoother, so that the connection between the torsion box 22 and the floor 1 is not easy to separate, avoiding the damage and tearing failure of the passenger compartment, and ensuring the integrity of the passenger compartment.

[0045] In the embodiment, since the first reinforcing portion 311 is connected to the side of the torsion box 22 facing the floor 1, when the vehicle suffers a frontal collision or an offset collision, that is, the side of the torsion box 22 away from the floor 1 bears external force, the first reinforcing portion 311 of the reinforcing part 31 can effectively support the side of the torsion box 22 facing the floor 1, which improves the frontal crash performance and offset crash performance of the vehicle, and improves the torsional resistance performance in offset collision.

[0046] In some embodiments, the reinforcing part 31 comprises a second reinforcing portion 312 connected to the side of the surrounding plate 21 facing the floor 1.

[0047] In the embodiment, the second reinforcing part 312 can enhance the connection strength between the surrounding plate 21 and the floor 1, so that the surrounding plate 21 and the floor 1 are not easily disconnected (for example, the local weld points between the surrounding plate 21 and the floor 1 are not easily torn) when the vehicle suffers from a frontal collision or an offset collision, and the passenger compartment integrity is ensured.

[0048] In the embodiment, the reinforcing member 31 can effectively conduct the forward or offset collision force, increase the passenger compartment bending resistance, and maximize the disconnection between the surrounding plate assembly 2 and the floor 1, such as avoiding the tearing of the weld points between the surrounding plate 21 and the floor 1.

[0049] In the embodiment, the reinforcing member 31 simultaneously connects the torsion box 22 and the surrounding plate 21, can improve the torsion resistance during the offset collision, and improve the crash performance of the surrounding plate assembly 2. Thus, the lateral force tears the weld points or makes the connection disconnected, and the passenger compartment tearing is avoided.

[0050] In the embodiment, the reinforcing member 31 connects the surrounding plate 21 and the floor 1, and the reinforcing member 31 connects the torsion box 22 and the floor 1. Thus, only the reinforcing member 31 needs to be added, the lightweight torsion box 22 is retained, the connection strength between the torsion box 22 and the floor 1, the torsion box 22 and the surrounding plate 21, and the surrounding plate 21 and the floor 1 is ensured, the stability of the front floor assembly structure is improved, and the torsion resistance of the surrounding plate assembly 2 is also improved.

[0051] In some embodiments, referring to Figure 3 As shown, the first reinforcing part 311 and the second reinforcing part 312 are an integral molding structure or a split structure.

[0052] In some embodiments, the first reinforcing part 311 and the second reinforcing part 312 are connected to each other, and the first reinforcing part 311 and the second reinforcing part 312 are an integral molding structure, which improves the structural strength of the reinforcing member 31, and also avoids the disconnection between the torsion box 22 and the surrounding plate 21, thereby improving the strength of the reinforcing member 31 and the front floor assembly structure.

[0053] In the embodiment, when the reinforcing member 31 is a sheet metal part, it can be made by stamping forming, so that the first reinforcing part 311 and the second reinforcing part 312 can be manufactured together by stamping forming, the assembly process between the first reinforcing part 311 and the second reinforcing part 312 is omitted, the manufacturing and installation efficiency of the reinforcing member 31 is improved, and the manufacturing cost of the reinforcing member 31 (i.e., the front floor assembly) is reduced.

[0054] In some embodiments, the first reinforcing part 311 and the second reinforcing part 312 are connected to each other, and the first reinforcing part 311 and the second reinforcing part 312 are in a split structure, which improves the flexibility of the component, and facilitates replacement and maintenance. In the embodiment, the first reinforcing part 311 and the second reinforcing part 312 can be connected to each other, or can be not connected (for example, the first reinforcing part 311 and the second reinforcing part 312 are arranged at intervals).

[0055] In some embodiments, the reinforcing member 31 has a first wall 313 and a second wall 314.

[0056] In the embodiment, the first wall 313 and the second wall 314 are connected to each other, for example, by an integral molding manner.

[0057] In some embodiments, the first wall 313 is arranged opposite to the floor 1 along a first direction X, and the second wall 314 is arranged opposite to the surrounding plate assembly 2 along a second direction Y, and the first direction X and the second direction Y are arranged at a certain angle.

[0058] In the embodiment, the first direction X and the second direction Y have an angle therebetween, and the angle is not equal to 0° or 180°.

[0059] In the embodiment, the first wall 313 and the second wall 314 have a certain angle therebetween. Compared with the scheme that the first wall 313 and the second wall 314 are parallel to each other, that is, the reinforcing member 31 adopts a straight structure, the reinforcing member 31 has higher supporting strength for the surrounding plate assembly 2 (for example, the torsion box 22 and / or the surrounding plate 21), and improves the structural strength of the front floor assembly. Moreover, the reinforcing member 31 has stronger anti-deformation (for example, anti-bending) capability.

[0060] In the embodiment, the angle between the first wall 313 and the second wall 314 matches the angle between the floor 1 and the surrounding plate 21. For example, the angle between the first wall 313 and the second wall 314 is greater than or equal to the angle between the floor 1 and the surrounding plate 21. Thus, the reinforcing member 31 is more fitted to the floor 1 and the surrounding plate 21, reduces the occupation of the reinforcing member 31 to the space in the vehicle, and increases the space in the vehicle.

[0061] For example, the plane where the first wall 313 is located is parallel to the plane where the floor 1 is located, and both are perpendicular to the first direction X. The plane where the second wall 314 is located is parallel to the plane where the surrounding plate 21 is located, and both are perpendicular to the second direction Y.

[0062] For example, when the angle between the running board of the vehicle and the carpet is between 130° and 140°, the arrangement is more ergonomic. At this time, the angle between the floor 1 and the coaming 21 can be between 140° and 150°. The angle between the first wall 313 and the second wall 314 can be correspondingly arranged to be between 140° and 160°, for example, 150°±5°, so that the vehicle is more ergonomic and the support strength of the reinforcement 31 for the coaming assembly 2 (such as the torsion box 22 and / or the coaming 21) is higher.

[0063] For example, the angle between the first wall 313 and the second wall 314 can be 145°, 146°, 147°, 148°, 149°, 150°, 151°, 152°, 153°, 154°, 155°. Of course, the angle between the first wall 313 and the second wall 314 can also be 140°, 141°, 142°, 143°, 144°, 156°, 157°, 158°, 159°, 160°.

[0064] In some embodiments, the reinforcement 31 has a first surface 315 facing the floor 1 and the coaming assembly 2, a second surface 316 facing away from the floor 1 and the coaming assembly 2, and a reinforcing groove 317.

[0065] In this embodiment, the first surface 315 can be the lower surface of the reinforcement 31, and the second surface 316 can be the upper surface of the reinforcement 31. The reinforcing groove 317 is a groove recessed on the surface of the reinforcement 31. Figure 3

[0066] In this embodiment, by providing the reinforcing groove 317 on the reinforcement 31 (for example, by forming the reinforcing groove 317 by stamping), the stiffness and strength of the reinforcement 31 can be improved, thereby improving the bending resistance and torsion resistance of the reinforcement 31, and then improving the support strength of the reinforcement 31 for the coaming assembly 2.

[0067] For example, the reinforcing groove 317 can extend along the front-rear direction of the vehicle, thereby improving the frontal crash and offset crash performance of the front floor assembly.

[0068] For example, the reinforcing groove 317 is provided on the first wall 313 and the second wall 314. The reinforcing groove 317 on the first wall 313 and the reinforcing groove 317 on the second wall 314 are in communication with each other.

[0069] For example, the reinforcing groove 317 is provided on the first reinforcing portion 311 and the second reinforcing portion 312. The number of reinforcing grooves 317 on the first reinforcing portion 311 is greater than the number of reinforcing grooves 317 on the second reinforcing portion 312, thereby improving the support strength of the reinforcement 31 (i.e., the first reinforcing portion 311) for the torsion box 22. ​

[0070] In some embodiments, the reinforcing groove 317 is recessed in the first surface 315 and / or the second surface 316.

[0071] In the present embodiment, the reinforcing groove 317 is only recessed in the first surface 315, for example, formed in the first surface 315 by means of stamping, which can reduce the manufacturing cost of the reinforcing member 31. Compared with the scheme of "the reinforcing groove 317 is only recessed in the second surface 316", the reinforcing member 31 occupies less space in the vehicle, thereby increasing the interior space of the vehicle.

[0072] In some embodiments, referring to Figure 4 As shown, the reinforcing assembly 3 comprises a first reinforcing seat 32 connected to the floor 1.

[0073] In the present embodiment, the first reinforcing part 311 is indirectly connected to the floor 1 through the first reinforcing seat 32, which avoids stress concentration caused by the direct connection of the first reinforcing part 311 to the floor 1. The first reinforcing part 311 is directly connected to the torque box 22, thereby reducing the manufacturing cost of the front floor assembly.

[0074] In some embodiments, one side of the first reinforcing part 311 is detachably connected to the first reinforcing seat 32, and the opposite side of the first reinforcing part 311 is detachably connected to the torque box 22.

[0075] In the present embodiment, the first reinforcing part 311 is detachably connected to the first reinforcing seat 32 and the torque box 22, which facilitates the installation and disassembly of the first reinforcing part 311, and also facilitates the maintenance and replacement of the first reinforcing part 311.

[0076] In the present embodiment, the first reinforcing part 311 can be connected to the first reinforcing seat 32 and the torque box 22 by means of bolts, flow drill screws (FDS), self-piercing rivets (SPR), thereby realizing detachable connection.

[0077] For example, when the first reinforcing part 311 is connected to the first reinforcing seat 32 and the torque box 22 by means of bolts, only by providing threaded holes on the first reinforcing seat 32 and threaded holes on the torque box 22 (for example, by modifying the casting mold of the torque box 22), the detachable installation of the first reinforcing part 311 can be realized, thereby reducing the manufacturing and installation cost of the front floor assembly.

[0078] In the embodiment, the original layout of the vehicle does not need to be changed, i.e., the main structure of the floor 1 and the torsion box 22 does not need to be changed, and the structural strength and manufacturing process of the floor 1 and the torsion box 22 are not affected, thereby reducing the design and production cost of the front floor assembly. Meanwhile, the front collision and offset collision performance of the vehicle is met, and the tearing of the welding points and the disconnection of the front floor assembly are avoided.

[0079] In the embodiment, when the front floor assembly is installed, the first reinforcing part 311 (i.e., the reinforcing member 31) can be implemented in a later assembly, i.e., the installation of the first reinforcing part 311 (i.e., the reinforcing member 31) is performed after the assembly of the surrounding plate assembly 2 and the floor 1.

[0080] In the embodiment, the torsion box 22 and the first reinforcing part 311 are detachably connected (e.g., bolted), which can connect different materials together and effectively ensure the integrity of the front floor assembly and simultaneously enhance the rigidity of the vehicle.

[0081] In the embodiment, the torsion box 22 and the first reinforcing part 311 (i.e., the reinforcing member 31) are effectively connected by bolts, which ensures that the structures of the two materials are stably connected when a collision occurs, and the collision force is effectively transmitted through the reinforcing member 31, thereby ensuring the passenger compartment integrity. The force transmission effect of the reinforcing member 31 is ensured to further improve the front collision and offset collision performance of the front floor assembly structure.

[0082] For example, the front and rear sides of the first reinforcing part 311 are connected with the torsion box 22 and the first reinforcing seat 32, respectively, which improves the front collision and offset collision performance of the front floor assembly and avoids the disconnection between the torsion box 22 and the floor 1.

[0083] For example, the first reinforcing seat 32 can be a beam structure extending along the front-rear direction of the vehicle, thereby improving the front collision and offset collision performance of the front floor assembly.

[0084] In some embodiments, referring to Figure 4 continuously, the reinforcing assembly 3 includes a second reinforcing seat 33 connected to the floor 1 and a mounting seat 34 connected to the surrounding plate 21.

[0085] In the embodiment, the second reinforcing part 312 is indirectly connected to the floor 1 through the second reinforcing seat 33, thereby avoiding stress concentration when the second reinforcing part 312 is directly connected to the floor 1. The second reinforcing part 312 is indirectly connected to the surrounding plate 21 through the mounting seat 34, thereby avoiding stress concentration when the second reinforcing part 312 is directly connected to the surrounding plate 21.

[0086] In some embodiments, one side of the second reinforcing part 312 is detachably connected to the second reinforcing seat 33, and the opposite side of the second reinforcing part 312 is detachably connected to the mounting seat 34.

[0087] In the embodiment, the second reinforcing part 312 is detachably connected to the second reinforcing seat 33 and the mounting seat 34, facilitating the installation and dismounting of the second reinforcing part 312, and facilitating the maintenance and replacement of the second reinforcing part 312.

[0088] In the embodiment, the second reinforcing part 312 can be connected to the second reinforcing seat 33 and the mounting seat 34 by bolts, flow drill screws (FDS), self-piercing rivets (SPR), so as to realize detachable connection.

[0089] For example, when the second reinforcing part 312 is connected to the second reinforcing seat 33 and the mounting seat 34 by bolts, only threaded holes need to be provided on the second reinforcing seat 33 and the mounting seat 34, so as to realize detachable installation of the second reinforcing part 312, and reduce the manufacturing and installation cost of the front floor assembly.

[0090] In the embodiment, the original layout structure of the vehicle does not need to be changed, that is, the main structure of the floor 1 and the surrounding plate 21 does not need to be changed, and the structural strength and manufacturing process of the floor 1 and the surrounding plate 21 are not affected, thereby reducing the design and production cost of the front floor assembly. At the same time, the front collision and offset collision performance of the vehicle is met, and the tearing of the internal welding point of the front floor assembly and the disconnection are avoided.

[0091] In the embodiment, when the front floor assembly is installed, the second reinforcing part 312 (i.e., the reinforcing part 31) can realize the rear assembly, that is, the surrounding plate assembly 2 is assembled with the floor 1, and then the second reinforcing part 312 (i.e., the reinforcing part 31) is installed.

[0092] In the embodiment, the bolts are used to effectively connect the surrounding plate 21 and the second reinforcing part 312 (i.e., the reinforcing part 31), and to effectively connect the second reinforcing part 312 (i.e., the reinforcing part 31) and the floor 1, so as to effectively transmit the collision force through the reinforcing part 31, and ensure the integrity of the passenger compartment. The force transmission effect of the reinforcing part 31 is ensured, so as to further improve the front collision and offset collision performance of the front floor assembly structure.

[0093] For example, the front and rear sides of the second reinforcing part 312 are connected to the mounting seat 34 and the second reinforcing seat 33 respectively, so as to improve the front collision and offset collision performance of the front floor assembly, and avoid disconnection between the surrounding plate 21 and the floor 1.

[0094] In some embodiments, continuing to refer to Figure 2 As shown, the first reinforcing seat 32 and the second reinforcing seat 33 are welded to the floor 1.

[0095] In the embodiment, the first reinforcing seat 32 and the second reinforcing seat 33 are welded at different positions of the floor 1, which can optimize the distribution of welding points on the floor 1, relieve the phenomenon of stress concentration, and improve the connection reliability between the floor 1 and the first reinforcing seat 32 and the second reinforcing seat 33.

[0096] In some embodiments, the mounting seat 34 is welded to the coaming 21.

[0097] In the embodiment, the welding position between the mounting seat 34 and the coaming 21 is different from the welding position between the floor 1 and the coaming 21, which can optimize the distribution of welding points on the coaming 21, relieve the phenomenon of stress concentration, and improve the connection reliability between the coaming 21 and the mounting seat 34.

[0098] For example, during the welding process of the floor 1 and the coaming assembly 2, the welding of the first reinforcing seat 32, the second reinforcing seat 33 and the mounting seat 34 is carried out synchronously, and after the welding is completed, the assembly (such as bolt connection) of the reinforcing member 31 is carried out, which optimizes the assembly process of the front floor 1 total length and does not affect the assembly process and manufacturing process between the floor 1 and the coaming assembly 2.

[0099] In some embodiments, continue to refer to Figure 4 As shown, the front floor assembly further includes a structural adhesive layer 4.

[0100] In the embodiment, the structural adhesive layer 4 can further enhance the connection strength of the front floor assembly and improve the crash performance of the front floor assembly.

[0101] For example, the structural adhesive layer 4 is an adhesive with high strength, strong carrying capacity, fatigue resistance and corrosion resistance. By bonding the inside of the front floor assembly through the structural adhesive layer 4, the lightweight effect of the front floor assembly can be further improved while ensuring the rigidity and strength requirements of the overall structure of the front floor assembly.

[0102] In some embodiments, continue to refer to Figure 5 As shown, the structural adhesive layer 4 covers at least the joint between the floor 1 and the coaming assembly 2.

[0103] In the embodiment, the structural adhesive layer 4 can cover the joint between the floor 1 and the coaming 21 and cover the joint between the floor 1 and the torsion box 22, so as to avoid the disconnection between the floor 1 and the coaming assembly 2 in the case of forward collision and offset collision.

[0104] In the embodiment, the structural adhesive layer 4 can also cover the joint between the torsion box 22 and the coaming 21, so as to improve the connection strength between the torsion box 22 and the coaming 21 and avoid the disconnection between the torsion box 22 and the coaming assembly 2 in the case of forward collision and offset collision.

[0105] For example, the surrounding plate 21 is welded to the front side of the floor 1, and the torsion box 22 is riveted to the front side of the floor 1. The torsion box 22 is riveted to the left side of the surrounding plate 21 or the right side of the surrounding plate 21.

[0106] According to a second aspect of the present application, a vehicle is provided, which comprises the front floor assembly described above. The vehicle has all the beneficial effects of the front floor assembly described above, which will not be repeated herein.

[0107] In the description of the present application, the terms "first", "second" are only for descriptive purpose, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0108] In the above embodiments, the description of each embodiment is focused on, and the parts not described in detail in a certain embodiment can be referred to the relevant description of other embodiments.
