[0035] The front floor assembly 10 of current vehicles is typically composed of multiple beams and flat plates welded together. This design complicates the manufacturing process and results in inconsistent weld quality, potentially weakening the overall strength and causing additional vibration and noise at the joints. Furthermore, specialized molds are required to produce each component, increasing waste output and manufacturing costs.

[0036] To this end, the present technical solution proposes a front floor assembly 10 for a vehicle having a body 20. The front floor assembly 10 includes:

[0037] The panel 100 is used to connect with the vehicle body 20;

[0038] The central channel beam 200 is provided on the panel 100 and extends along the length direction of the vehicle;

[0039] A seat cross member 300 is provided on the panel 100 and extends along the width direction of the vehicle;

[0040] The panel 100 , the center channel beam 200 and the seat cross beam 300 are integrally formed.

[0041] In the technical solution of the present invention, the panel 100, the center channel beam 200 and the seat cross beam 300 in the traditional vehicle structure are made into an integral part by an integrated molding method, so that the front floor assembly 10 is integrated into an integral part, which reduces the number of parts. In this way, the process of re-splicing the parts in the traditional processing steps can be omitted, thereby reducing the processing difficulty. The entire front floor assembly 10 is formed in one piece. Compared with the method of forming the panel 100, the center channel beam 200 and the seat cross beam 300 separately, it can reduce the waste generated in the processing process and reduce the material cost. Moreover, since the various components are formed in one piece, there is no problem of poor splicing between the various components, which is also conducive to improving the processing quality and overall strength of the entire front floor assembly 10.

[0042] like Figures 1 to 5 In one embodiment of the present invention, the front floor assembly 10 is arranged at the floor position of the passenger compartment of the vehicle body 20. The front floor assembly 10 includes a panel 100. The panel 100 is a flat plate structure. The front end of the panel 100 is connected to the rear wall of the engine compartment, the left and right sides of the panel 100 are connected to the door sill beams, and the rear side of the panel 100 is connected to the rear floor. A central channel beam 200 is provided in the middle of the panel 100. The central channel beam 200 extends along the length direction of the vehicle. One end of the central channel beam 200 is connected to the rear wall of the engine compartment, and the other end is connected to the rear floor. The central channel beam 200 can play a role in transmitting force along the length direction of the vehicle to improve the overall structural strength of the vehicle body 20. In addition, a seat cross beam 300 is provided on the floor. The seat cross beam 300 extends along the width direction of the vehicle, and the two ends of the seat cross beam 300 are respectively connected to the door sill beams on both sides. Then, the seat cross beam 300 can play the role of transmitting the force in the width direction of the vehicle. In addition, the seat cross beam 300 is also integrated with a seat installation function. The car seat can be installed on the seat cross beam 300, and then installed on the vehicle body 20. In this solution, the above-mentioned panel 100, the center channel beam 200 and the seat cross beam 300 are processed and formed as one piece. The three components can be cast or stamped out at one time as a complete unit. This can reduce the assembly links between multiple individual parts and simplify the processing technology of the front floor assembly 10. Compared with the separate production of each component, the one-piece processing can reduce the scrap and waste generated during the processing, which helps to save costs. In addition, it can also eliminate the problem of splicing gaps or poor welding between different parts in the traditional structure, which can improve the reliability and overall strength of the front floor assembly 10.

[0043] In one embodiment of the present invention, the panel 100, the central channel beam 200 and the seat cross beam 300 are integrally stamped or injection molded; the integral molding method of the front floor assembly 10 can also be flexibly selected according to the material or design requirements. For example, the panel 100, the central channel beam 200 and the seat cross beam 300 can be made of metal materials such as aluminum alloy or high-strength steel, and the above three components can be integrally stamped, thus ensuring that the front floor assembly 10 has excellent mechanical properties and durability; of course, in order to improve the lightweight level, the front floor assembly 10 can also be made of non-metallic materials such as plastic, and the panel 100, the central channel beam 200 and the seat cross beam 300 can be processed by integral injection molding, thus reducing the weight of the front floor assembly 10, improving the lightweight level of the vehicle, and helping to reduce automobile energy consumption and improve automobile economy. Furthermore, in another embodiment of the present invention, to achieve both lightweight and high strength, the front floor assembly 10 may be made of a non-metallic composite material. For example, the front floor assembly 10 may be made of glass fiber reinforced polypropylene. The glass fiber reinforces the polypropylene, thereby ensuring lightweight while also maintaining the strength of the front floor assembly 10.

[0044] like Figure 3 In one embodiment of the present invention, the seat cross beam 300 has a first cavity with an opening at the bottom, the middle channel beam 200 has a second cavity with an opening at the bottom, and the front floor assembly 10 further includes a reinforcing structure 400, which is arranged in the first cavity and / or the second cavity; wherein, the front floor assembly 10 can be formed by bending thin plates of equal thickness into one piece. Such a structural design can not only provide the necessary support and strength, but also help to reduce processing difficulty and save materials. The reinforcing structure 400 can be a reinforcing rib protruding from the first cavity and the second cavity, or it can be a thin plate attached to the inner wall of the first cavity and the second cavity to increase the wall thickness. By adding the reinforcing structure 400, the overall deformation resistance of the front floor assembly 10 can be enhanced, and the structural strength of the front floor assembly 10 can be improved.

[0045] like Figure 4 , in one embodiment of the present invention, the reinforcement structure 400 includes a reinforcement beam 410 and / or a reinforcement plate 420;

[0046] Among them, the reinforcing beam 410 is embedded in the first cavity and extends along the width direction of the vehicle, and the reinforcing beam 410 is connected to the inner wall of the first cavity; the reinforcing plate 420 is connected to the edge of the opening of the second cavity and extends along the length direction of the vehicle, and the reinforcing plate 420 and the reinforcing beam 410 are connected to each other.

[0047] In this embodiment, the reinforcing beam 410 can be a structure such as a tubular beam. The length of the reinforcing beam 410 can be equal to the length of the seat cross beam 300. The reinforcing beam 410 is embedded in the seat cross beam 300 and can be connected to the inner wall of the first cavity by bonding, riveting or welding. This can improve the rigidity of the seat cross beam 300 and prevent it from deforming when subjected to lateral force. In this solution, the reinforcing beam 410 can be processed by hot air expansion molding. The outer peripheral wall of the reinforcing beam 410 matches the shape of the inner wall of the first cavity. When the reinforcing beam 410 is embedded in the first cavity, the reinforcing beam 410 and the first cavity can be completely attached. The reinforcement beam 410 can be combined to enhance the support provided by the seat cross member 300. Furthermore, the reinforcement plate 420 can be a plate-shaped structural member. The reinforcement plate 420 is positioned at the edge of the opening of the second chamber of the center tunnel beam 200 and secured to the center tunnel beam 200 by welding, riveting, or bonding. The reinforcement plate 420 extends along the length of the vehicle and can be equal to the overall length of the front floor assembly 10. The shape of the reinforcement plate 420 can be adapted to and conform to the shape of the location in which it is installed. This helps to enhance the rigidity of the center tunnel beam 200 along the length of the vehicle, thereby improving the rigidity of the entire front floor assembly 10. Furthermore, the reinforcement beam 410 and the reinforcement plate 420 can be connected to each other, thereby supporting each other and increasing the force transmission path of the front floor assembly 10, further enhancing the rigidity and torsional resistance of the seat cross member 300 and the center tunnel beam 200. In this solution, the provision of the reinforcing beam 410 and the reinforcing plate 420 not only serves to improve the rigidity, but also is equivalent to dividing the panel 100, the center channel beam 200 and the seat cross beam 300 into multiple areas, which is beneficial to reducing the transmission of vibration between the various areas, preventing resonance, and achieving the effect of improving NVH performance.

[0048] like Figure 4 In one embodiment of the present invention, first connecting points 411 are provided at both ends of the reinforcement beam 410, and second connecting points 421 are provided at both ends of the reinforcement plate 420. The first connecting points 411 and the second connecting points 421 are used to connect to the vehicle body 20. In this embodiment, the first connecting points 411 and the second connecting points 421 may be pre-set holes, protrusions, or other structures that facilitate connection. The first connecting points 411 secure the reinforcement beam 410 to the vehicle body 20 through welding, riveting, or other methods, and the second connecting points 421 secure the reinforcement plate 420 to the vehicle body 20 through welding, riveting, or other methods. This improves the connection strength between the entire front floor assembly 10 and the vehicle body 20, increases the force transmission path between the front floor assembly 10 and the vehicle body 20, and helps improve the collision safety of the vehicle.

[0049] In one embodiment of the present invention, the first connection position 411 is configured as a first connection hole, through which a fastener passes and is locked to the vehicle body 20. The specific number of the first connection holes can be adjusted according to actual needs. The fastener can be a bolt. After passing through the first connection hole, the fastener can be fixed to the vehicle body 20 with a nut. This not only ensures the reliability of the connection between the reinforcement beam 410 and the vehicle body 20, but also reduces assembly difficulty. Similarly, the second connection position 421 is configured as a second connection hole. The central channel beam 200 is provided with a third connection hole opposite the second connection hole. The fastener passes through the second and third connection holes and is locked to the vehicle body 20. The specific number of the second and third connection holes can also be adjusted according to actual needs. The fastener can be a bolt. After passing through the second and third connection holes, the fastener can be fixed to the vehicle body 20 with a nut. In this way, the central channel beam 200, the reinforcement plate 420, and the vehicle body 20 are connected together, greatly improving the reliability of the connection between the front floor assembly 10 and the vehicle body 20, while also reducing assembly difficulty.

[0050] In one embodiment of the present invention, the seat cross beam 300 includes a front cross beam 310 and a rear cross beam 3230. The front cross beam 310 and the rear cross beam 3230 are arranged at intervals along the length of the vehicle, and the height of the front cross beam 310 is greater than the height of the rear cross beam 3230. In addition, the top surface of the front cross beam 310 and the top surface of the rear cross beam 3230 are both inclined surfaces inclined toward the rear of the vehicle. During assembly, the seat is placed on the front cross beam 310 and the rear cross beam 3230. The height of the front cross beam 310 is greater than the height of the rear cross beam 3230, which allows the seat to have a backward tilt during installation, so that the passenger's back fits better against the seat when riding, thereby improving riding comfort. Especially during long-distance driving or riding, this design helps to reduce the discomfort caused by sitting for a long time.

[0051] In one embodiment of the present invention, a reinforcing beam 410 is provided in both the front cross beam 310 and the rear cross beam 3230, and a supporting structure is provided in the reinforcing beam 410 in the rear cross beam 3230; the provision of the reinforcing beam 410 can further increase the rigidity of the front cross beam 310 and the rear cross beam 3230, thereby ensuring the structural strength of the seat installation position; in addition, since the weight of the passenger will be more concentrated on the rear cross beam 3230 after the seat is tilted backward, a supporting structure can be added inside the reinforcing beam 410 in the rear cross beam 3230 to better bear the weight of the passenger and prevent deformation. In this embodiment, the supporting structure can be a transverse or longitudinal support rib provided on the reinforcing beam 410. The supporting structure can be evenly distributed on the reinforcing beam 410 or locally reinforced in key stress areas. For ease of processing, the supporting structure can be integrally formed with the reinforcing beam 410.

[0052] like Figure 5In one embodiment of the present invention, the reinforcing beam 410 is a tubular beam structure. The reinforcing beam 410 has a bottom wall and a top wall along the vehicle height direction. The supporting structure is configured as a support portion 412 protruding from the bottom wall toward the top wall. The support portion 412 is supported on the side of the top wall facing the bottom wall. This embodiment provides a design form of the supporting structure. In this embodiment, the reinforcing beam 410 is a hollow tubular beam structure. The reinforcing beam 410 has a top wall and a bottom wall along the vehicle height direction. The support portion 412 can be integrally formed on the bottom wall. Specifically, the support portion 412 can be a protruding structure formed by bending the bottom wall toward the top wall. The protrusion is supported on the bottom surface of the top wall. The support portion 412 extends along the length direction of the reinforcing beam 410 to both ends of the reinforcing beam 410. When the top wall of the support beam is under pressure, the support portion 412 can support the top wall upward, thereby improving the pressure bearing capacity of the reinforcing beam 410. In this solution, the integrated design of the support portion 412 and the reinforcing beam 410 can reduce the difficulty of processing the reinforcing beam 410 and help reduce manufacturing costs.

[0053] The present invention also provides a vehicle, which includes a body 20. A mounting opening is provided at the bottom of the body 20, and a front floor assembly 10 is fastened to the mounting opening. The front floor assembly 10 is welded or adhesively fixed to the periphery of the mounting opening. The specific structure of the front floor assembly 10 refers to the above-mentioned embodiment. Since this vehicle adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0054] The above are merely exemplary embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
