Description

Technical Field

[0001] This application relates to the technical field of automobiles, and more particularly to a floor assembly and vehicle. Background Technology

[0002] Modern automobiles, as convenient and efficient means of transportation, have become an indispensable part of people's travel and freight transport. Their complex structure encompasses many key components such as the engine, chassis, and body, all working together to ensure the vehicle's normal operation. A car's performance and safety are closely linked, especially the body structure design, which directly affects the vehicle's strength, rigidity, and occupant protection in collisions and other accidents.

[0003] In the prior art, the seat crossbeam is generally composed of two beams, one in front of the seat and one in the rear. As a key component of the lower body assembly, this structure has a significant impact on the strength of the front floor, the weight of the vehicle, the collision stiffness of the vehicle, the precision of the body-in-white, and the safety of the vehicle.

[0004] However, existing technical solutions have many drawbacks, mainly in the following aspects: First, the structure is thin, with both the front and rear crossbeams of the seat being single-layer force transmission structures, resulting in poor load-bearing structure; second, the strength is insufficient, and the crossbeams are prone to deformation in side collision scenarios, thus affecting the safety protection performance of passengers; third, the stiffness is lacking, and the existing structure transmits a large force to the seat when subjected to a side collision, endangering passenger safety. Utility Model Content

[0005] This application addresses, to at least some extent, one of the technical problems in the related art.

[0006] Therefore, this application aims to provide a floor assembly and vehicle in which the crossbeam is designed as a layered structure including a lower crossbeam plate and an upper crossbeam plate. Through the layered force transmission path, the collision force can be effectively dispersed, reducing the deformation of the crossbeam during a collision. This solves the technical problem in the prior art where the seat experiences excessive force, endangering passenger safety.

[0007] To achieve the above objectives, in a first aspect, this application provides a floor assembly, comprising:

[0008] floor;

[0009] The crossbeam includes a lower plate and an upper plate; wherein:

[0010] The lower plate of the crossbeam is disposed on the upper surface of the floor, and the length direction of the lower plate of the crossbeam is the same as the width direction of the floor;

[0011] The upper plate of the crossbeam is disposed on the side of the lower plate of the crossbeam away from the floor, and the upper plate of the crossbeam and the lower plate of the crossbeam are arranged parallel to each other; a first cavity is formed between the upper plate of the crossbeam and the lower plate of the crossbeam.

[0012] In this technical solution, the crossbeam is designed as a layered structure comprising a lower and upper crossbeam plate. This design overcomes the limitations of traditional single-layer force transmission structures. By using layered force transmission paths, it effectively disperses collision forces and reduces the deformation of the crossbeam during a collision. In a side impact, the lower and upper crossbeam plates work together to form a more stable structure, significantly improving the crossbeam's bending and torsional resistance. This structure not only enhances safety during side impacts but also reduces the risk of passenger injury due to excessive crossbeam deformation. Furthermore, the layered structure design provides a foundation for subsequent reinforcement arrangement and material optimization, further improving the overall structural performance.

[0013] In some embodiments of this application, at least one mounting seat is provided on the side of the upper plate of the crossbeam away from the lower plate of the crossbeam, and the mounting seat is used to install a seat.

[0014] In the technical solution, the mounting base provides a reliable connection point for the installation of key components such as the seat, and this design enhances the stability of the seat installation.

[0015] In some embodiments of this application, the mounting base is partially connected to the upper plate of the crossbeam and partially connected to the lower plate of the crossbeam; or, the mounting base is completely connected to the upper plate of the crossbeam.

[0016] In this technical solution, this connection method makes the connection between the mounting bracket and the crossbeam more robust. Through this design, the forces generated during the installation of components such as the seat can be better distributed across the upper and lower plates of the crossbeam. In the event of a collision, the impact force is layered and limited, preventing the force from being effectively transmitted to the seat through the mounting bracket, thus achieving cushioning and reducing the risk of seat deformation during a collision, thereby further improving passenger safety. Furthermore, this connection method also facilitates subsequent manufacturing and assembly, improving production efficiency and product quality.

[0017] In some embodiments of this application, a central channel protrudes upward from the middle of the floor, and the length direction of the central channel is the same as the length direction of the floor; both sides of the width direction of the central channel are installation areas, and the crossbeams are provided in each installation area.

[0018] In the technical solution, seats can be installed on both sides of the installation area, namely the left and right seats, which is more in line with modern car design.

[0019] In some embodiments of this application, multiple beams are provided at intervals along the length of the floor.

[0020] In this technical solution, each seat is mounted on multiple crossbeams. These crossbeams better disperse the impact force and reduce deformation during a collision. In a side impact, the multiple crossbeams work together to form a more stable structural frame, significantly improving the vehicle's side impact safety.

[0021] In some embodiments of this application, a connecting longitudinal beam is provided on the side of the floor away from the crossbeam; the connecting longitudinal beam is located in the installation area.

[0022] In this technical solution, the structural strength and rigidity of the floor assembly are further enhanced by connecting longitudinal beams. These beams work in conjunction with the crossbeams to form a more robust structural frame, better bearing the various loads generated during vehicle operation, improving vehicle stability and safety, and also contributing to increased vehicle durability and reducing structural deformation or damage caused by long-term use.

[0023] In some embodiments of this application, a connector is provided on the side of the connecting longitudinal beam away from the central channel. The connector is connected to the connecting longitudinal beam and the floor. The side of the connector away from the central channel is used to connect the sill beam.

[0024] In this technical solution, the connectors ensure a reliable connection between the longitudinal beams and the floor and sill beams, forming a unified structural frame. This connection method effectively transmits and disperses various forces generated during vehicle operation, improving the vehicle's structural stability and overall integrity. Simultaneously, the connector design also strengthens the connection between the sill beams and the floor, enhancing the strength of the vehicle's side structure, improving safety during side collisions, and reducing the risk of vehicle deformation or damage due to weak connections between the sill beams and the floor.

[0025] In some embodiments of this application, a second cavity is formed between the connector and the floor.

[0026] In the technical solution, the bending design of the connector forms a second cavity, which improves the structural strength of the connector, enhances the firmness and reliability of the connection, and plays a role in mitigating and blocking the collision force during the collision process, thus protecting the safety of the cab.

[0027] In addition, this application also provides a vehicle, including:

[0028] The vehicle body includes the floor assembly as described above;

[0029] A seat, which is mounted on the crossbeam.

[0030] In the technical solution, the design of the floor assembly can effectively improve the side collision safety of the vehicle, reduce the injury to passengers during a collision, and also help improve the vehicle's handling performance and stability, enhance the overall performance and quality of the vehicle, and strengthen the vehicle's competitiveness in the market.

[0031] In some embodiments of this application, the vehicle body further includes door assemblies; the door assemblies are disposed on both sides of the floor width direction;

[0032] The door assembly includes a sill beam that is connected to the floor.

[0033] In the technical solution, the connection between the door sill beam and the floor can further enhance the strength and rigidity of the vehicle side, improving the safety of the vehicle in a side collision.

[0034] As can be seen from the above technical solutions, additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0050] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0051] It should be noted that in the automotive industry, seat crossbeams are generally composed of two beams: the front and rear mounting beams of the seat. As a key component of the lower body assembly, this structure has a significant impact on the strength of the front floor, the weight of the vehicle, the collision stiffness of the vehicle, the precision of the body-in-white, and the overall safety of the vehicle.

[0052] In existing technologies, the floor assembly structure is thin, with both the front and rear seat mounting beams being single-layer force-transmitting structures, resulting in inadequate load-bearing capacity. Furthermore, the floor assembly lacks sufficient strength, making the beams prone to deformation in side-impact collisions, thus affecting passenger safety. Additionally, the floor assembly lacks rigidity; in existing structures, the forces transmitted to the seat during side-impact collisions are relatively large, endangering passenger safety.

[0053] Based on this, this application proposes a floor assembly and vehicle, which uses a crossbeam design to create a layered structure including a lower crossbeam plate and an upper crossbeam plate. This layered force transmission path effectively disperses collision forces. Upon impact, the upper and lower crossbeam plates separately absorb the force, reducing the force directly transmitted from the crossbeam to the seat and solving the problem of passenger safety in existing technologies.

[0054] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0055] Referring to all the accompanying drawings, in one illustrative embodiment of the floor assembly and vehicle of this application, the floor assembly includes a floor 100. The floor 100 serves as the foundation of the vehicle, ensuring the torsional rigidity of the vehicle body and improving the vehicle's handling stability under complex road conditions. Furthermore, the floor 100 provides a reasonable pathway for in-vehicle wiring and piping, making the layout of the vehicle's electrical and power transmission systems more organized and facilitating installation and maintenance.

[0056] In this application, taking the vehicle placed horizontally as an example, the lower surface of the floor 100 is the side facing the ground, and the length direction of the floor 100 is the length direction of the vehicle, which can also be understood as the front-back direction of the vehicle. The width direction of the floor 100 is the width direction of the vehicle.

[0057] In some embodiments, the floor assembly further includes a cross beam. The cross beam provides a stable support point for seat installation, ensuring that the seat can withstand the weight of passengers and various dynamic forces during vehicle driving, and guaranteeing the riding safety and stability.

[0058] Furthermore, the cross beam includes a cross beam lower plate 200 and a cross beam upper plate 300; the cross beam is designed as a layered structure including the cross beam lower plate 200 and the cross beam upper plate 300. This design breaks through the limitations of the traditional single-layer force transmission structure. Through the upper and lower layered force transmission paths, it can effectively disperse the collision force and reduce the deformation amount of the cross beam during collision.

[0059] Even further, the cross beam lower plate 200 is disposed on the upper surface of the floor 100, and the length direction of the cross beam lower plate 200 is the same as the width direction of the floor 100. The cross beam upper plate 300 is disposed on the side of the cross beam lower plate 200 away from the floor 100, and the cross beam upper plate 300 is arranged parallel to the cross beam lower plate 200. During a side collision, the cross beam lower plate 200 and the upper plate can work together to form a more stable structure, significantly enhancing the bending and torsional resistance of the cross beam. This structure not only enhances the safety of the vehicle during side collision, but also reduces the risk of harm to passengers caused by excessive deformation of the cross beam. In addition, the design of the layered structure also provides a basis for subsequent rib arrangement and material optimization, further improving the performance of the overall structure.

[0060] In some embodiments, a first cavity is formed between the cross beam upper plate 300 and the cross beam lower plate 200. The first cavity provides a force collapse space and a buffering function. During a side collision of the vehicle, the first cavity allows a certain relative displacement between the cross beam upper plate 30 and the cross beam lower plate 200, thereby absorbing and dispersing the collision energy. The design of this collapse space can effectively reduce the possibility of the collision force being directly transmitted to the passenger seat, reduce the impact force received by the passengers, and enhance the safety of the vehicle during side collision.

[0061] In some embodiments, a reference plane is defined, the reference plane is parallel to the length direction of the floor 100 and perpendicular to the floor 100. The cross-sectional line of the cross beam lower plate 200 on the reference plane is in a "ji" shape, which can also be understood as the cross section of the cross beam lower plate 200 is in an "n" shape.

[0062] Further, the lower beam plate 200 includes a first vertical segment and a first horizontal segment. Among them, the length direction of the first vertical segment is arranged along the width direction of the floor 100, the width direction of the first vertical segment is vertically arranged, and the two first vertical segments are parallel and arranged at intervals along the length direction of the floor 100. The first horizontal segment is horizontally arranged, and the length direction of the first horizontal segment is arranged along the width direction of the floor 100. The two sides of the width direction of the first horizontal segment are respectively connected to the tops of the two first vertical segments. The bottom of the first vertical segment is connected to the floor 100 to form the lower beam plate 200.

[0063] It should be noted that, in order to ensure the structural strength of the lower beam plate 200, the lower beam plate 200 is integrally formed, that is, the first vertical segment and the first horizontal segment are integrally formed.

[0064] In some embodiments, in order to ensure the connection strength between the lower beam plate 200 and the floor 100, the bottom of the first vertical segment is bent horizontally with a first flanging, and the first flanging is fitted to the floor 100 to improve the connection strength.

[0065] Further, in order to facilitate manual connection of the lower beam plate 200 and the floor 100, the extending direction of the first flanging is away from the other first vertical segment. In this way, the two first flangings are located outside, which is convenient for subsequent manual installation.

[0066] In some embodiments, the preferred connection method between the lower beam plate 200 and the floor 100 is welding. The welding connection strength is high, which can significantly improve the structural strength and integrity of the floor assembly. However, other connection methods such as bolts and rivets are not excluded in this application.

[0067] Specifically, the lower beam plate 200 is connected to the floor 100 through the first flanging.

[0068] In some embodiments, the cross-sectional line of the upper beam plate 300 on the reference plane is in a "ji" shape, which can also be understood as the cross-section of the upper beam plate 300 is in an "n" shape.

[0069] Further, the upper beam plate 300 includes a second vertical segment and a second horizontal segment. Among them, the width direction of the second vertical segment is vertically arranged, the length direction of the second vertical segment is arranged along the width direction of the floor 100, and the two second vertical segments are parallel and arranged at intervals along the length direction of the floor 100. The second horizontal segment is horizontally arranged, and the length direction of the second horizontal segment is arranged along the width direction of the floor 100. The two sides of the width direction of the second horizontal segment are respectively connected to the tops of the two second vertical segments. The bottom of the second vertical segment is connected to the lower beam plate 200.

[0070] In some embodiments, the preferred distance between the second horizontal segment and the first horizontal segment is 40 millimeters.

[0071] In some embodiments, the second vertical segment is respectively attached to the sidewall of the corresponding first vertical segment, and the second vertical segment is connected to the first vertical segment to realize the connection between the upper plate 300 and the lower plate 200 of the crossbeam. This connection method can effectively enhance the overall structural strength and stability of the crossbeam, ensuring that the various parts of the crossbeam can work together when subjected to external forces or loads, and avoiding structural failure due to loosening or deformation of the connection parts. Furthermore, during the production process, the distance between the second horizontal segment and the first horizontal segment can be adjusted according to requirements, thereby adjusting the height of the upper plate 300 of the crossbeam, which is convenient for adjustment according to different vehicle models.

[0072] Specifically, the second vertical segment is connected to the first vertical segment by welding. Alternatively, the second vertical segment can also be connected to the first vertical segment by bolts, screws, rivets, or other similar structures.

[0073] In another embodiment, the second vertical segment is connected to the first horizontal segment. In this design, the bottom of the second vertical segment is supported by the first horizontal segment, resulting in stronger vertical load-bearing capacity.

[0074] It is understandable that after the upper plate 300 of the crossbeam is connected to the lower plate 200 of the crossbeam, a first cavity is formed between the two second vertical sections, the first horizontal section and the second horizontal section.

[0075] In some embodiments, at least one mounting seat 400 is provided on the side of the upper crossbeam 300 away from the lower crossbeam 200, and the mounting seat 400 is used to mount the seat. The mounting seat 400 provides a reliable connection point for the installation of critical components such as the seat, and this design enhances the stability of the seat installation.

[0076] Preferably, each crossbeam upper plate 300 is provided with two mounting seats 400. The two mounting seats 400 meet the current vehicle seat installation requirements and can provide more reliable support and fixing points to ensure the firmness of the connection.

[0077] In some embodiments, the mounting base 400 is rectangular or trapezoidal. For ease of manufacturing, the bottom of the mounting base 400 is open. The bottom of the mounting base 400 is connected to the upper plate 300 of the crossbeam.

[0078] In some embodiments, the bottom of the mounting base 400 is completely fixed to the upper crossbeam plate 300. It can be completely fixed to the second horizontal section of the upper crossbeam plate 300, or partially fixed to the second horizontal section and partially fixed to the second vertical section. In the event of a collision, the force must first be transmitted through the lower crossbeam plate 200 to the upper crossbeam plate 300, and then through the upper crossbeam plate 300 to the mounting base 400 and the seat to achieve force transmission. By dissipating force during the transmission process, the force cannot be effectively transmitted to the seat, thus achieving cushioning, reducing the risk of seat deformation in a collision, and further improving passenger safety.

[0079] Specifically, the bottom of the mounting base 400 is provided with a second flange, which is attached to and connected to the upper plate 300 of the crossbeam.

[0080] Preferably, the second flange is connected to the upper plate 300 of the crossbeam by welding, which results in higher welding strength and improved structural strength. Alternatively, the second flange can also be connected to the upper plate 300 of the crossbeam by bolts, screws, rivets, or other similar structures.

[0081] In other embodiments, the mounting base 400 is partially connected to the upper plate 300 of the crossbeam and partially connected to the lower plate 200 of the crossbeam. This connection method makes the connection between the mounting base 400 and the crossbeam more robust. Through this design, the forces generated during the installation of components such as the seat can be better distributed across the upper and lower plates of the crossbeam. During a collision, the impact force is layered and restricted, preventing the force from being effectively transmitted to the seat through the mounting base 400, thus achieving cushioning, reducing the risk of seat deformation during a collision, and further improving passenger safety. Furthermore, this connection method also facilitates subsequent manufacturing and assembly, improving production efficiency and product quality.

[0082] Specifically, the bottom of the mounting base 400 is provided with a second flange, part of which is connected to the upper plate 300 of the crossbeam, and the other part is connected to the lower plate 200 of the crossbeam.

[0083] Preferably, one-quarter of the second flange is installed on the lower plate 200 of the crossbeam, and the remaining three-quarters is installed on the upper plate 300 of the crossbeam. This configuration allows for better stress distribution and support for the seat when the crossbeam is under load. In the event of a collision, the impact force is stratified and cannot be effectively transferred to the mounting base 400, reducing the risk of seat deformation during a collision and thus effectively improving the safety performance of the cab.

[0084] In some embodiments, a central channel 101 protrudes upward from the middle of the floor 100, and the length direction of the central channel 101 is the same as the length direction of the floor 100; both sides of the width direction of the central channel 101 are mounting areas, and each mounting area is provided with a crossbeam. Seats can be installed in both mounting areas, namely a left seat and a right seat, which is more in line with modern automotive design.

[0085] Specifically, the central aisle 101 is located in the middle of the floor 100 so that the width of the installation areas on both sides is the same, so that the space occupied by the seats on both sides is similar, thus ensuring passenger comfort.

[0086] In some embodiments, the lower beam plate 200 of the crossbeam can extend beyond the central channel 101. Alternatively, the lower beam plates 200 of the two mounting areas can be understood as interconnected.

[0087] In some embodiments, multiple crossbeams are spaced apart along the length of the floor 100. Each seat is mounted on a corresponding number of crossbeams, which can better disperse the impact force and reduce the deformation of the crossbeams during a collision. In a side collision, the multiple crossbeams can work together to form a more stable structural frame, significantly improving the vehicle's side collision safety.

[0088] In some embodiments, two mounting seats 400 are provided on every two crossbeams, so there are four mounting seats 400 on two crossbeams, and every four mounting seats 400 correspond to one seat. The four mounting seats 400 correspond to the four corners of the bottom of the seat, providing a stable connection point for the seat and ensuring the stability and safety of the seat during use.

[0089] Specifically, the positions of the four mounting seats 400 on each pair of crossbeams correspond to the four corners of the rectangle, which facilitates the installation of the seat.

[0090] In some embodiments, the central channel 101 of the floor 100 can gradually flatten out from the front end of the floor 100 to the rear end, that is, the central channel 101 structure is not visible at the rear end of the floor 100. Front seats are installed on both sides of the central channel 101 at the front end of the floor 100.

[0091] In some embodiments, the beam structure in this application may be applied to the front seat or the rear seat.

[0092] In some embodiments, a connecting longitudinal beam 500 is provided on the side of the floor 100 opposite to the crossbeam; the connecting longitudinal beam 500 is located in the installation area. The connecting longitudinal beam 500 further enhances the structural strength and rigidity of the floor assembly. The connecting longitudinal beam 500 can work in conjunction with the crossbeam to form a more stable structural frame, better withstand various loads generated during vehicle operation, improve vehicle stability and safety, and also help improve vehicle durability, reducing structural deformation or damage caused by long-term use.

[0093] Furthermore, the longitudinal beam 500 extends along the same length as the floor 100, significantly enhancing the overall structural strength and stability of the floor 100. Because the longitudinal beam extends along the length of the floor 100, it effectively distributes the load borne by the floor 100 evenly, preventing localized stress concentration and thus improving the floor 100's bending and torsional resistance.

[0094] In some embodiments, each mounting area corresponds to a connecting longitudinal beam 500, which is located in the middle of the mounting area. This facilitates support for the mounting area.

[0095] In another embodiment, each installation area corresponds to multiple connecting longitudinal beams 500, further enhancing the strength of the support for the floor 100.

[0096] Furthermore, the cross-section of the connecting longitudinal beam 500 is in an inverted "Ji" shape, which can also be understood as the cross-section of the connecting longitudinal beam 500 being in a "U" shape.

[0097] Specifically, the connecting longitudinal beam 500 includes a third vertical segment and a third horizontal segment. Among them, the width direction of the third vertical segment is vertically arranged, and the length direction of the third vertical segment is arranged along the length direction of the floor 100. The two third vertical segments are parallel and arranged at intervals along the width direction of the floor 100. The third horizontal segment is horizontally arranged, and the length direction of the third horizontal segment is arranged along the length direction of the floor 100. The two sides in the width direction of the third horizontal segment are respectively connected to the bottoms of the two second horizontal segments. The top of the third vertical segment is connected to the lower surface of the bottom plate.

[0098] In some embodiments, the top of the third vertical segment is bent horizontally with a third flange, and the third flange is fitted to the floor 100 to improve the connection strength.

[0099] Furthermore, to facilitate manual connection of the connecting longitudinal beam 500 to the floor 100, the extending direction of the third flange is away from the other third vertical segment. In this way, the two third flanges are located outside, facilitating subsequent manual installation.

[0100] Preferably, the connecting longitudinal beam 500 and the floor 100 are connected by welding. In addition, the connecting longitudinal beam 500 and the floor 100 can also be connected by structures such as bolts, screws, and rivets.

[0101] Furthermore, the connection between the connecting longitudinal beam 500 and the floor 100 is achieved by connecting the third flange to the floor 100.

[0102] In some embodiments, a connector 600 is provided on the side of the connecting longitudinal beam 500 away from the middle channel 101. The connector 600 is connected to the connecting longitudinal beam 500 and the floor 100, and the side of the connector 600 away from the middle channel 101 is used to connect to the sill beam 701. The setting of the connector 600 enables the connecting longitudinal beam 500 to be reliably connected to the floor 100 and the sill beam 701, forming an integral structural framework. This connection method can better transmit and disperse various forces generated during vehicle driving, improving the structural stability and integrity of the vehicle. At the same time, the design of the connector 600 also makes the connection between the sill beam 701 and the floor 100 more firm, enhancing the strength of the vehicle side structure, improving the safety during vehicle side collision, and reducing the risk of vehicle deformation or damage caused by the insecure connection between the sill beam 701 and the floor 100.

[0103] In some embodiments, a plurality of connectors 600 are arranged at intervals along the length direction of the floor 100. The arrangement of the plurality of connectors 600 can significantly improve the overall stability and bearing capacity of the structure of the floor 100.

[0104] In some embodiments, a second cavity is formed between the connector 600 and the floor 100. The second cavity enables the connector 600 to produce a certain degree of elastic deformation when subjected to a collision force, thereby playing a role in buffering and energy absorption. This design can effectively disperse and absorb the impact force generated during a side collision of the vehicle, reduce the direct transmission of force, and lower the risk of intrusion into the passenger compartment, significantly improving the side collision safety of the vehicle.

[0105] In some embodiments, the connector 600 includes a first connecting portion 601 and a second connecting portion 602. The first connecting portion 601 and the second connecting portion 602 are distributed along the length direction of the floor 100. The first connecting portion 601 is used to connect the floor 100, and the second connecting portion 602 is used to connect two adjacent first connecting portions 601. The bent design of the connector 600 improves its structural strength, enhances the firmness and reliability of the connection, and plays a role in alleviating and blocking the collision force during the collision process, protecting the safety of the cab.

[0106] Furthermore, a second cavity is formed between the second connecting portion 602, the first connecting portion 601 and the floor 100.

[0107] It can also be understood that the first connecting portion 601 is in an inverted "U" shape or "W" shape. The first connecting portion 601 is connected to the sill beam and the connecting longitudinal beam 500 by spot welding. It plays a role in alleviating and blocking the collision force during the collision process, protecting the safety of the cab.

[0108] It should be noted that, preferably, the first connecting portion 601 has two forms. Among them, the first form is that the connector 600 includes two first connecting portions 601 and one second connecting portion 602. One side of the first connecting portion 601 is connected to the floor 100, and both sides of the second connecting portion 602 are respectively connected to the sides of the corresponding first connecting portion 601 away from the floor 100.

[0109] Specifically, a rectangular or trapezoidal second cavity is formed among the two first connecting portions 601, the second connecting portion 602 and the floor 100. [[ID=第十九]]

[0110] The second form is that the connector 600 includes four first connecting portions 601 and two second connecting portions 602. Each first connecting portion 601 is spaced apart along the length of the floor 100, and one side of each first connecting portion 601 is connected to the floor 100. Taking the distribution direction of the first connecting portions 601 as an example, they are first connecting portions 601A, 601B, 601C, and 601D. First connecting portions 601B and 601C are connected to each other at the connection point to the floor 100. The two sides of one second connecting portion 602 are connected to the sides of the first connecting portions 601A and 602B away from the floor 100. The two sides of the other second connecting portion 602 are connected to the sides of the first connecting portions 601C and 602D away from the floor 100. This makes the connector 600 "W" shaped. In this form, two second cavities are formed between the connector 600 and the floor 100.

[0111] In some embodiments, in order to improve the structural strength of the connector 600, the connector 600 is a one-piece molded part.

[0112] Furthermore, this application also provides a vehicle, including a body and seats, the body including the floor assembly as described above; the seats are mounted on a crossbeam. The design of the floor assembly can effectively improve the side-impact safety of the vehicle, reduce injury to passengers during a collision, and also help improve the vehicle's handling performance and stability, enhance the overall performance and quality of the vehicle, and strengthen the vehicle's competitiveness in the market.

[0113] Furthermore, the seat is mounted on the mounting base 400.

[0114] In some embodiments, the vehicle body also includes a door assembly 700; the door assembly 700 is disposed on both sides of the floor 100 in the width direction; the door assembly 700 includes a sill beam 701, which is connected to the floor 100. The connection between the sill beam 701 and the floor 100 can further enhance the strength and rigidity of the vehicle side, and improve the safety of the vehicle in a side collision.

[0115] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
