Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle technology, and more particularly to a floor frame, a seat assembly, a floor assembly, and a vehicle. Background Technology
[0002] The existing front floor frame includes multiple stamped structural components, including a left reinforcing plate, a central channel, and a right reinforcing plate arranged sequentially in a left-right direction, and a first seat crossbeam and a second seat crossbeam connected by the central channel and arranged in a front-rear direction. The left and right reinforcing plates are both connected to the front side of the first seat crossbeam. The connected stamped structural components are assembled by welding to form the front floor frame.
[0003] The aforementioned front floor frame has the following defects:
[0004] Firstly, the large number of parts, complicated assembly process, and low assembly efficiency result in high processing costs for the entire front floor frame. Moreover, when multiple stamped parts are joined together by welding, the large welding error can easily increase the dimensional error of the entire front floor frame.
[0005] Secondly, the structural strength at the connection points of various structural components is not high, forming a weak area in the front floor. In the event of a collision, the weak area is more prone to connection failure, resulting in higher maintenance costs.
[0006] Thirdly, the seat frame is processed independently of the front floor frame. After the front floor frame is assembled, the front and rear ends of the seat frame are then installed onto the first and second seat crossbeams, respectively. This further increases the vehicle assembly process, reduces assembly efficiency, and increases assembly costs. Furthermore, seat frame mounting points need to be pre-reserved on both the first and second seat crossbeams. To ensure that both ends of the seat frame can be accurately installed onto the mounting points on the first and second seat crossbeams, the relative dimensions between these mounting points are critical, increasing the precision required for machining and further increasing processing costs.
[0007] Therefore, there is an urgent need for a floor frame to solve the above-mentioned technical problems. Summary of the Invention

[0024] And / or, the top of the connector is formed with a brake pedal mounting bracket;
[0025] And / or, the side of the rear crossbeam of the seat away from the front crossbeam of the seat is formed with a rear floor mounting structure.
[0026] As one feasible technical solution for the aforementioned floor frame, a frame connector is connected between at least two adjacent seat frames, and the two ends of the frame connector are respectively connected to the middle of the two seat frames in the front-back direction.
[0027] Alternatively, at least two frame connectors are connected between at least two adjacent seat frames, and the at least two frame connectors are arranged at intervals in the front-to-back direction.

[0050] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.
[0051] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0052] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0053] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.
[0054] For ease of description and understanding, in the embodiments of the present invention, along the length direction of the vehicle, the direction from the front to the rear of the vehicle is the front-to-back direction; along the width direction of the vehicle, the direction from the driver's seat to the passenger seat is the left-to-right direction; and the height direction of the vehicle is the vertical direction.
[0055] Embodiments of the present invention provide a floor frame to reduce the molding difficulty, processing cost, and assembly cost of the floor frame, while improving its structural strength, integration level, and processing efficiency. This floor frame can be a front floor frame or a rear floor frame; the structure of the floor frame will be described in detail below using a front floor frame as an example.
[0056] like Figures 1 to 5 As shown, the floor frame is a one-piece molded structural component. The floor frame includes a front seat crossbeam 1, a rear seat crossbeam 2, and at least two seat frames 3. The front seat crossbeam 1 and the rear seat crossbeam 2 are connected by a beam connector 8. The rear seat crossbeam 2 is spaced apart on the rear side of the front seat crossbeam 1 along the front-rear direction of the vehicle. The at least two seat frames 3 are spaced apart along the left-right direction of the vehicle. The front end of each seat frame 3 is connected to the front seat crossbeam 1, and the rear end of each seat frame 3 is connected to the rear seat crossbeam 2.
[0057] Connecting the front crossbeam 1 and rear crossbeam 2 of the seat via a row of seat frames 3 forms a single, integrally molded floor frame. This reduces the number of parts in the floor frame, eliminates the need for connections between independent components, simplifies the entire floor frame molding process, and improves processing efficiency. Integrating the seat frame 3 with the front and rear crossbeams also increases the overall integration of the floor frame, allows for more precise dimensional control, improves dimensional accuracy, and avoids dimensional errors caused by welding between independent components. Furthermore, it enhances the connection strength between the seat frame 3 and the front and rear crossbeams, improving the safety and reliability of the floor frame.
[0058] Furthermore, integrating the seat frame 3, the front crossbeam 1, and the rear crossbeam 2 into one unit can significantly improve the performance of the area near the seat, thereby enhancing the user's perceived experience.
[0059] In some embodiments, the floor skeleton is an integrally cast aluminum part. Compared with the all-steel floor skeleton or the steel-aluminum hybrid floor skeleton in the prior art, the overall weight of the vehicle is reduced by reducing the overall density of the floor skeleton, and the cost of the floor skeleton can be significantly reduced.
[0060] Exemplarily, die-casting is used when the floor skeleton is integrally formed. Die-casting applies pressure to the molten raw material, enabling the raw material to have higher forming precision, that is, the dimensional tolerance of the formed part is smaller and the surface precision is higher, thus achieving precise control of the dimensions of the floor skeleton and further shortening the dimension chain. In some other embodiments, the floor skeleton can also be formed by casting.
[0061] In some embodiments, as Figure 1 and Figure 6 shown, both the front seat crossbeam 1 and the rear seat crossbeam 2 have cavities 100 with openings facing downwards, which is beneficial to reducing the weight of the front seat crossbeam 1 and the rear seat crossbeam 2 and achieving lightweight of the floor skeleton; forming the cavity 100 by die-casting is beneficial to improving the structural strength of the front seat crossbeam 1 and the rear seat crossbeam 2; in practical applications, wiring harnesses, pipelines and other general assembly parts can be arranged in the cavity 100 to make full use of the space on the floor skeleton.
[0062] Exemplarily, the above cavity 100 is a U-shaped through-hole penetrating in the left-right direction, and the opening edge of the U-shaped through-hole is turned outwards to form an outward flange, so that the front seat crossbeam 1 and the rear seat crossbeam 2 form a "ji" - shaped opening structure. When a side collision occurs, the "ji" - shaped opening structure can ensure that the collision force can be continuously transmitted on the front seat crossbeam 1 and the rear seat crossbeam 2, thus well transmitting the collision force.
[0063] In some embodiments, as Figure 1 and Figure 6 shown, the top surface of the front seat crossbeam 1 and the rear seat crossbeam 2 is provided with a reinforcing groove 200, and a reinforcing boss 300 is formed on the bottom wall of the cavity 100. Forming the above reinforcing groove 200 and reinforcing boss 300 by die-casting is beneficial to improving the structural strength of the front seat crossbeam 1 and the rear seat crossbeam 2.
[0064] In some embodiments, as Figure 1 and Figure 2As shown, the floor skeleton further includes a middle reinforcement member 5, a first side reinforcement member 6, and a second side reinforcement member 7, all of which are located on the front side of the front seat cross member 1. Among them, the rear end of the middle reinforcement member 5 is connected to the front seat cross member 1; the middle reinforcement member 5 is provided with the first side reinforcement member 6 on both sides in the left - right direction, and the first side reinforcement member 6 is connected to the front seat cross member 1; on the side of the first side reinforcement member 6 facing away from the middle reinforcement member 5, there is a second side reinforcement member 7 connected, and the second side reinforcement member 7 and the first side reinforcement member 6 connected to it are arranged at an angle. Exemplarily, the middle reinforcement member 5 and the first side reinforcement member 6 both extend in the front - rear direction.
[0065] Integrating the middle reinforcement member 5, the first side reinforcement member 6, the second side reinforcement member 7, the front seat cross member 1, the rear seat cross member 2, and the seat skeleton 3 all into an integrated unit, there are more integrated parts and a higher integration rate. At the same time, it can improve the lightweight effect of the floor skeleton.
[0066] In addition, by adding the second side reinforcement member 7, the structural strength of the entire floor skeleton can be improved. Moreover, when a side collision occurs to the vehicle, the second side reinforcement member 7 can absorb the impact force generated by the collision, improving the anti - collision performance, reliability, and stability of the entire floor skeleton.
[0067] Exemplarily, there are two first side reinforcement members 6 and two second side reinforcement members 7. The two first side reinforcement members 6 are symmetrically arranged with respect to the middle reinforcement member 5, and the two second side reinforcement members 7 are symmetrically arranged with respect to the middle reinforcement member 5.
[0068] In some embodiments, as Figure 1 and Figure 2 shown, the middle reinforcement member 5, the first side reinforcement member 6, and the second side reinforcement member 7 all have a cavity 100 with an opening facing downwards, which is beneficial to reducing the weight of the middle reinforcement member 5 and achieving the lightweight of the floor skeleton; forming this cavity 100 by die - casting is beneficial to improving the structural strength of the middle reinforcement member 5, the first side reinforcement member 6, and the second side reinforcement member 7; in actual application, wiring harnesses, pipelines and other general assembly parts can be arranged in the cavity 100 to make full use of the space on the floor skeleton.
[0069] Exemplarily, the cavity 100 on the above - mentioned middle reinforcement member 5 and the cavity 100 on the first side reinforcement member 6 are both U - shaped through - holes that penetrate in the front - rear direction, and the cavity 100 on the second side reinforcement member 7 is a U - shaped through - hole that penetrates along its extending direction. The opening edges of each U - shaped through - hole are turned outwards to form an outward - turned edge, so that the middle reinforcement member 5, the first side reinforcement member 6, and the second side reinforcement member 7 all form a "C" - shaped opening structure. When a side collision occurs, the "C" - shaped opening structure can ensure that the collision force can be continuously transmitted on the middle reinforcement member 5 and the first side reinforcement member 6, thus well transmitting the collision force.
[0070] The cavities 100 on the middle reinforcing member 5, the first side reinforcing member 6, the second side reinforcing member 7, the front crossbeam 1 of the seat, and the rear crossbeam 2 of the seat are interconnected, which is beneficial for arranging wiring harnesses, pipes, and other assembly components in the interconnected cavities 100.
[0071] In some embodiments, such as Figure 1 and Figure 2 As shown, the top surface of the first side reinforcement 6 is provided with a reinforcing groove 200, and a reinforcing boss 300 is formed on the bottom wall of the cavity 100 on the first side reinforcement 6. The above-mentioned reinforcing groove 200 and reinforcing boss 300 are formed by die casting, which is beneficial to improving the structural strength of the middle reinforcement 5.
[0072] In some embodiments, such as Figure 1 and Figure 2 As shown, the end of the second side reinforcement 7 that is connected to the first side reinforcement 6 is closer to the front crossbeam 1 of the seat than the other end.
[0073] For example, the included angle between the second side reinforcement 7 and the first side reinforcement 6 connected thereto is an acute angle. This arrangement helps to improve the impact resistance of the floor frame. The specific angle between the second side reinforcement 7 and the first side reinforcement 6 connected thereto can be determined through repeated experiments, and will not be specifically set here.
[0074] In some embodiments, the end of the second side reinforcement 7 on the left side away from the middle reinforcement 5 is flush with the left end of the front seat crossbeam 1 and the left end of the rear seat crossbeam 2, and the end of the second side reinforcement 7 on the right side away from the middle reinforcement 5 is flush with the right end of the front seat crossbeam 1 and the right end of the rear seat crossbeam 2. This helps to improve the impact resistance of the floor frame and enhance its safety performance.
[0075] In some embodiments, such as Figure 2 , Figure 7 and Figure 9 As shown, the beam connector 8 is located between the front crossbeam 1 and the rear crossbeam 2 of the seat. The front end of the beam connector 8 is connected to the front crossbeam 1, and the rear end of the beam connector 8 is connected to the rear crossbeam 2. Exemplarily, two beam connectors 8 are provided, spaced apart along the left-right direction on opposite sides of the central reinforcing member 5, and symmetrically arranged about the central reinforcing member 5. It should be noted that the number of beam connectors 8 is not limited to two; it can also be one, in which case the beam connector 8 and the central reinforcing member 5 can be arranged facing each other along the front-back direction; it can also be three, four, or more, with multiple beam connectors 8 spaced apart along the left-right direction.
[0076] For example, the front crossbeam 1 and the rear crossbeam 2 of the seat each correspond to a beam connector 8. The front crossbeam 1 and the corresponding beam connector 8 are arranged facing each other in the front-rear direction. The beam connector 8 has a cavity 100 with its opening facing downward, which helps to reduce the weight of the middle reinforcement 5 and achieve lightweighting of the floor frame. The cavity 100 is formed by die casting, which helps to improve the structural strength of the beam connector 8. The cavity 100 on the front crossbeam 1 and the cavity 100 on the corresponding beam connector 8 are connected, and the cavity 100 on the rear crossbeam 2 and the cavity 100 on the corresponding beam connector 8 are also connected. This allows for the arrangement of wiring harnesses, pipes and other assembly components in the cavity 100, making full use of the space on the floor frame.
[0077] In some embodiments, such as Figure 2 , Figure 7 and Figure 9 As shown, a connector is provided between the first side reinforcement 6 and the middle reinforcement 5. By providing the connector, the structural strength of the first side reinforcement 6 can be reduced in the event of a side collision. At the same time, in conjunction with the second side reinforcement 7, the impact resistance of the floor frame can be improved.
[0078] For example, the connector includes a first connector 13 and a second connector 14. A first connector 13 is arranged between the first side reinforcement 6 and the middle reinforcement 5 on the left side, and a second connector 14 is arranged between each first side reinforcement 6 and the middle reinforcement 5. The two second connectors 14 are arranged facing each other in the left-right direction, and the first connector 13 is located in front of the second connector 14.
[0079] In some embodiments, both the first connector 13 and the second connector 14 have an upward-facing first groove that extends through the entire structure in the left-right direction; both the first connector 13 and the second connector 14 have a downward-facing second groove that extends through the entire structure in the left-right direction. Forming the first and second grooves by die casting improves the structural strength of the first connector 13 and the second connector 14, and also gives them better impact absorption performance, thereby improving the overall impact resistance of the floor frame and contributing to the lightweighting of the floor frame.
[0080] In some embodiments, such as Figure 1 and Figure 11As shown, multiple battery mounting brackets 9 are formed at the bottom of the front crossbeam 1 and the rear crossbeam 2 of the seat, and battery mounting brackets 9 are also formed at the bottom of the two second connectors 14. The power battery is mounted to the floor frame through the multiple battery mounting brackets 9. Integrating the battery mounting brackets 9 and the floor frame into one unit can reduce the number of parts, improve the degree of integration, and improve the assembly efficiency of the power battery and the floor frame. For example, the bottom wall of the reinforcing groove 200 on the front crossbeam 1 and the rear crossbeam 2 of the seat is recessed downwards, so that the bottom wall of the corresponding cavity forms a protruding battery mounting bracket 9. The bottom wall of the first groove is recessed downwards, so that the lower surface of the first connector 13 forms a protruding battery mounting bracket 9. The bottom wall of the second groove is recessed downwards, so that the lower surface of the second connector 14 forms a protruding battery mounting bracket 9. It should be noted that the structure of the battery mounting bracket 9 is not limited to the above structure, and can also be other structures. The specific structure can be set according to the installation requirements of the power battery, which will not be described in detail here.
[0081] For example, five battery mounting brackets 9 are arranged on both the front crossbeam 1 and the rear crossbeam 2 of the seat. The battery mounting brackets 9 on the front crossbeam 1 and the rear crossbeam 2 are arranged facing each other in the front-rear direction. The middle battery mounting bracket 9 is positioned directly opposite the central reinforcement member 5 in the front-rear direction. The two pairs of battery mounting brackets 9 on the left side of the central reinforcement member 5 are symmetrically arranged about the beam connector 8 on the same side. The two pairs of battery mounting brackets 9 on the right side of the central reinforcement member 5 are symmetrically arranged about the beam connector 8 on the same side. Each of the two second connectors 14 is provided with one battery mounting bracket 9 and is symmetrically arranged about the central reinforcement member 5.
[0082] In some embodiments, such as Figure 1 and Figure 2 As shown, the top of the reinforcing member 5 integrates an electrical module mounting bracket 10, and the top of the first connecting member 13 is formed with a brake pedal mounting bracket 11. This arrangement integrates both the electrical module mounting bracket 10 and the brake pedal mounting bracket 11 with the floor frame, reducing the number of parts and increasing the level of integration. It should be noted that the electrical module mainly refers to the automatic driving controller, vehicle motion threshold controller, etc.
[0083] For example, multiple electrical module mounting brackets 10 are provided, and multiple electrical module mounting brackets 10 protrude from the top surface of the central reinforcing member 5, and brake pedal mounting bracket 11 protrudes from the bottom wall of the first groove on the first connecting member 13.
[0084] The structures of the aforementioned electrical module mounting bracket 10 and brake pedal mounting bracket 11 are not limited to the structures described above; other structures can also be used. The specific configuration can be determined based on the actual installation requirements of the electrical module and brake pedal, and will not be detailed here. Furthermore, the positions of each mounting bracket are not limited to the positions described above; appropriate mounting brackets can be set according to the specific vehicle component layout for different vehicle models. When the floor frame is a rear floor frame, the vehicle components installed on the integrally formed mounting bracket on the rear floor frame differ, and will not be detailed here.
[0085] In some embodiments, such as Figure 11 As shown, the inner wall of the cavity 100 is formed with reinforcing ribs 400. There are three types of reinforcing ribs 400, referred to as first reinforcing ribs, second reinforcing ribs and third reinforcing ribs respectively. For example, the first side reinforcing member 6 and the middle reinforcing member 5 are each provided with a plurality of first reinforcing ribs extending in the left-right direction and spaced apart in the front-back direction, and a second reinforcing rib extending in the front-back direction; the second side reinforcing member 7 is provided with a plurality of first reinforcing ribs extending in the front-back direction and spaced apart in the left-right direction, and a second reinforcing rib extending in the extension direction of the second side reinforcing member 7 itself; the beam connector 8 is provided with a plurality of first reinforcing ribs extending in the left-right direction and spaced apart in the front-back direction, and a second reinforcing rib extending in the front-back direction; the front crossbeam 1 and the rear crossbeam 2 of the seat are each provided with a plurality of first reinforcing ribs extending in the front-back direction and spaced apart in the left-right direction, a second reinforcing rib extending in the left-right direction, and a third reinforcing rib extending in the front-back direction and located between the two beam connectors 8.
[0086] The third reinforcing rib is disposed on the cavity sidewall of the cavity 100 on the front crossbeam 1 and the rear crossbeam 2 of the seat; the first reinforcing rib on the front crossbeam 1 and the rear crossbeam 2 of the seat is located on the outer side of the two beam connectors 8 in the left-right direction; the second reinforcing rib on the first side reinforcing member 6 is connected to the second reinforcing rib on the corresponding beam connector 8. The second reinforcing rib is disposed on the cavity bottom wall and cavity sidewall of the cavity 100, and no reinforcing rib 400 is disposed on the outer flange of each cavity 100.
[0087] Because the floor frame is a one-piece cast aluminum component, it avoids the disruption of the overall vehicle structure path caused by the separate processing of parts. It can also add a large number of reinforcing ribs 400 to the weak areas of the floor frame, thus solving the drawback that the weak areas cannot be reinforced when using a steel split floor frame, thereby maximizing the structural performance of the floor frame.
[0088] In some embodiments, such as Figure 1As shown, a rear floor mounting structure 12 is formed on the side of the rear crossbeam 2 facing away from the front crossbeam 1. Exemplarily, the rear floor mounting structure 12 is a through hole that runs vertically through the rear crossbeam 2 and is used to pass fasteners through it. There are multiple through holes, which are arranged at intervals in the left and right directions. The through holes are located on the outward flange of the side of the rear crossbeam 2 facing away from the front crossbeam 1. The floor frame is connected to the rear floor by fasteners.
[0089] Embodiments of the present invention also provide a seat assembly, including a seat and a floor frame provided in any of the above embodiments, wherein the seat is mounted on the seat frame 3.
[0090] Specifically, such as Figure 4 and Figure 5 As shown, the seat is movably mounted on the seat frame in the front-to-back direction. Specifically, the seat frame 3 includes a front seat frame 3a, a rear seat frame 3b, and a seat mounting part 3c. The front end of the seat mounting part 3c is connected to the front seat frame 3a and extends forward from it, while the rear end is connected to the rear seat frame 3b and extends rearward from it. The seat mounting part 3c is located above the front and rear seat frames 3a and 3b, and is supported by them. The seat is movably connected to the seat mounting part in the front-to-back direction, allowing for position adjustment. Furthermore, by supporting the seat mounting part 3c with the front and rear seat frames 3a and 3b, the height of the seat mounting part 3c is increased, providing ample installation space for the seat and preventing interference between the seat and the front and rear crossbeams 1 and 2.
[0091] The front end of the seat mounting part 3c is mounted to the seat frame 3 on the front crossbeam 1, and the rear end of the seat mounting part 3c is mounted to the seat frame 3 on the rear crossbeam 2. The seat mounting part 3c is a guide rail structure, and the seat is movably mounted on the seat mounting part 3c in the front-to-back direction. This configuration allows the seat to be adjusted in the front-to-back position. It should be noted that in other embodiments, the seat can also be fixedly mounted on the seat mounting part.
[0092] For example, when the above-mentioned floor frame is used for the front floor of a vehicle, there are two seats, namely a driver's seat and a passenger seat. Each seat is equipped with two seat frames 3. Each seat and the corresponding two seat frames 3 slide in the front-back direction to improve the stability of the seat when moving back and forth.
[0093] It should be noted that the number of seat frames 3 can be flexibly selected according to different vehicle models or different seat models.
[0094] For example, such as Figures 7 to 10As shown, the top surface of the seat mounting part 3c has an upward-facing U-shaped groove. The upper edges of the opposite side walls of the U-shaped groove are folded inward to form inward flanges. The space between the inward flanges and the bottom wall of the U-shaped groove forms a sliding groove. This sliding groove and the seat slide together in the front-back direction, providing guidance for the seat's front-back position adjustment. Simultaneously, the inward flanges also limit the seat's position in the vertical direction, improving the stability of the seat during sliding. It should be noted that the structure of the seat mounting part 3c is not limited to the above structure; any structure that enables the seat mounting part 3c and the seat to slide together in the front-back direction is acceptable. Further examples will not be provided here.
[0095] In some embodiments, a frame connector 4 connects at least two adjacent seat frames 3. For example, a frame connector 4 connects two adjacent seat frames 3 corresponding to the same seat, with the left and right ends of the frame connector 4 connected to the middle of the two seat frames 3 in the front-rear direction. Connecting the two seat frames 3 with the frame connector 4 reduces the deformation of the middle of the seat frame 3 after the seat is installed on the two seat frames 3, thus improving the stability of the seat. It should be noted that the frame connector 4 between two adjacent seat frames 3 corresponding to the same seat is not limited to one; it can be two, three, or more, in which case the multiple frame connectors 4 are arranged at intervals in the front-rear direction. Frame connectors 4 can also be arranged between two adjacent seat frames 3 of different seats.
[0096] For example, the two seat frames 3 corresponding to the same seat are symmetrically arranged about the corresponding beam connectors 8. The two seats are located directly behind the two first side reinforcements 6 in a one-to-one correspondence. The two seat frames 3 corresponding to the same seat are arranged between the first side reinforcements 6 in the left-right direction and are symmetrically arranged about the first side reinforcements 6. The seat frames 3 on the left and right sides of the central reinforcement 5 are symmetrically arranged about the central reinforcement 5.
[0097] In some embodiments, a seat limiting part 30 is installed on the top of the seat mounting part 3c. The seat limiting part 30 may be a limiting protrusion or the like installed on the seat mounting part 3c. The specific installation method of the seat limiting part 30 may be a plug-in connection, a fastening connection, or the like, and will not be specifically limited here.
[0098] Embodiments of the present invention also provide a floor assembly, including a floor body and the seat assembly provided in any of the above embodiments, with a floor frame connected to the floor body. Specifically, the floor body is located above the floor frame and is fixedly installed on the floor frame.
[0099] The floor frame of this floor assembly is made of a one-piece molded aluminum casting, which reduces the overall weight of the floor frame and contributes to its lightweight design. It also reduces the number of parts and has a high degree of integration, integrating the battery mounting bracket 9, electrical module mounting bracket 10, and brake pedal mounting bracket 11 onto the floor frame, making it easier to ensure dimensional accuracy and reducing welding errors. Because the floor frame uses a one-piece molded structure, it eliminates the need for sealant compared to existing split floor frames.
[0100] In terms of overall layout, the assembly requirements of each installation point can be met by optimizing the local morphology of the cast aluminum parts. There is no need to set up separate installation brackets on the floor frame. Moreover, the connection requirements of the rear floor can be met by directly integrating the rear floor installation structure 12 on the rear crossbeam 2 of the seat.
[0101] Embodiments of the present invention also provide a vehicle including the aforementioned floor assembly, which reduces the weight of the vehicle, reduces the number of parts, and lowers the processing cost of the floor frame, thereby improving vehicle production efficiency and helping to comprehensively reduce the overall cost of the vehicle.
[0102] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
