Description

Technical Field

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

[0002] Vehicles are machines driven by fuel or electricity to carry people or goods. As an important load-bearing component of the chassis system, the front floor assembly has a significant impact on the vehicle's noise, vibration, and harshness (NVH) performance, driving comfort, and the stability of key components due to its structural stiffness and vibration characteristics.

[0003] In related technologies, the reinforced structure of vehicle floor has limitations in dealing with complex dynamic loads and is difficult to provide effective vibration reduction and structural stiffness. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a vehicle floor and a vehicle that can effectively buffer vibration and impact, thereby improving the vehicle's NVH performance.

[0005] In a first aspect, this application provides a vehicle floor, including a floor body and a reinforcing structure. The floor body is provided with a reinforcing region. The reinforcing structure is located in the reinforcing region and includes a plurality of reinforcing protrusions. The plurality of reinforcing protrusions are continuously arranged along the extension direction of the floor body, and each reinforcing protrusion is arranged adjacent to at least two reinforcing protrusions.

[0006] The vehicle floor provided in this application includes a floor body and a reinforcing structure. The reinforcing structure is disposed within a reinforced area of ​​the floor body to increase the structural strength of the vehicle floor. Based on this, the reinforcing structure includes multiple reinforcing protrusions, which are continuously arranged along the extension direction of the floor body to form a continuous buffering reinforcing structure. Each reinforcing protrusion is adjacent to at least two other reinforcing protrusions. Each reinforcing protrusion can transmit vibration impacts in different directions to the at least two adjacent reinforcing protrusions, thereby effectively dispersing vibration energy and improving vibration reduction. Furthermore, the multiple reinforcing protrusions increase the cross-sectional area of ​​the vehicle floor, improving its torsional and bending resistance, and optimizing its stiffness to provide stable support and positioning for the components fixed to the vehicle floor. Compared with the strip-shaped reinforcing ribs used in related technologies, the vehicle floor of this application has multiple continuous reinforcing protrusions, which can effectively buffer vibration impacts, improve the stiffness of the vehicle floor, and thus improve the NVH performance of the vehicle.

[0007] In some implementations, the reinforcing protrusion includes a first surface, the floor body includes a structural surface, the structural surface and the first surface are located on the same side of the vehicle floor, the first surface is provided to protrude relative to the floor body in a direction away from the structural surface, and at least a portion of the first surface extends along an arc.

[0008] In some implementations, the reinforcing protrusion includes a second surface that is recessed relative to the floor body in a direction away from the structural surface, and the distance between the second surface and the first surface is uniform.

[0009] In some implementations, a first transition portion is provided between two adjacent reinforcing protrusions. The first transition portion includes a third surface that is in contact with the first surface. The third surface is recessed relative to the floor body in a direction close to the structural surface to form a drainage groove.

[0010] In some implementations, both the first and third surfaces are arc surfaces. The first surface has a first radial dimension, and the third surface has a second radial dimension. The ratio of the second radial dimension to the first radial dimension is in the range of 0.2-0.3.

[0011] In some implementations, the first transition portion extends along a straight line and has a preset size along its extension direction, and multiple first transition portions corresponding to the same reinforcing protrusion have the same preset size.

[0012] In some implementations, the plurality of reinforcing protrusions include at least two columns of protrusions arranged sequentially along a first direction, each column of protrusions including at least two reinforcing protrusions arranged sequentially along a second direction, the second direction having an angle with the first direction.

[0013] In some implementations, the reinforcing protrusions in two adjacent columns of protrusions are staggered along a second direction.

[0014] In some implementations, the vehicle floor includes at least two reinforcing regions, and / or the vehicle floor includes at least two floor bodies; and each reinforcing region of the floor body is provided with a reinforcing structure.

[0015] Secondly, this application provides a vehicle, including a body and a vehicle floor as described in the first aspect, the vehicle floor being connected to the body.

[0016] In the vehicle described in this application, including the vehicle floor, the reinforced area of ​​the vehicle floor is provided with multiple continuous reinforcing protrusions, which can effectively buffer vibration and impact, improve the rigidity of the vehicle floor, and thus improve the NVH performance of the vehicle.

[0030] The following is a detailed description of this application.

[0031] This application provides a vehicle, which is a machine powered by fuel or electricity used to transport people or goods. The vehicle can be a sedan, SUV, sport utility vehicle (SUV), multi-purpose vehicle (MPV), truck, bus, public transport, etc. The vehicle can refer to a fuel-powered vehicle, an electric vehicle, or a hybrid vehicle.

[0032] Vehicles typically include a front floor assembly, which, as a crucial load-bearing component of the chassis system, significantly impacts the vehicle's noise, vibration, and harshness (NVH) performance, driving comfort, and the stability of key components due to its structural stiffness and vibration characteristics. With increasing user demands for vehicle comfort, safety, and lightweight design, the front floor assembly has shown limitations in handling vibration and noise transmission under complex operating conditions. To improve its vibration resistance and structural stiffness, reinforced structural designs are commonly employed.

[0033] In some technical solutions, the reinforcement structure is configured with corrugated stiffeners, E-shaped stiffeners, or strip stiffeners. These reinforcement structures improve stiffness by increasing the local thickness of the front floor or changing its geometry. However, these types of reinforcement structures still have certain limitations when dealing with complex dynamic loads. The overall weight reduction space is limited, and in some cases, stress concentration may affect the structural durability. Traditional reinforcement structures are usually continuous structures, making it difficult to simultaneously meet the requirements of stiffness improvement and functional design, such as drainage path optimization.

[0034] Therefore, embodiments of this application also provide a vehicle floor, with reference to Figure 1 , Figure 2 and Figure 3 The vehicle floor includes a floor body 100 and a reinforcing structure 200. The floor body 100 is provided with a reinforcing region 110. The reinforcing structure 200 is located in the reinforcing region 110 and includes a plurality of reinforcing protrusions 210. The plurality of reinforcing protrusions 210 are continuously arranged along the extension direction of the floor body 100, and each reinforcing protrusion 210 is arranged adjacent to at least two reinforcing protrusions 210.

[0035] In some examples, the floor body 100 is the front floor of the vehicle, for example, the floor body 100 is located on the side of the vehicle's B-pillar near the front of the vehicle; in other examples, the floor body 100 is the rear floor of the vehicle, for example, the floor body 100 is located on the side of the vehicle's B-pillar near the rear of the vehicle; and in still other examples, the floor body 100 is an integral floor covering both the front and rear of the vehicle.

[0036] It should be noted that the reinforced area 110 can be any area of ​​the floor body 100. For example, the reinforced area 110 is an area away from the floor beam; or, for example, the reinforced area 110 is an area that fixes or supports structures such as pipes.

[0037] In some examples, the reinforcing structure 200 is disposed on the surface of the floor body 100 facing or away from the interior space; in other examples, the reinforcing structure 200 and the floor body 100 are configured as a continuous structure along the extension direction of the floor body 100.

[0038] In some examples, the reinforcing protrusion 210 refers to a structure that protrudes at least partially relative to the floor body 100; in other words, the projection of the floor body 100 along the extension direction of the floor body 100 does not completely cover the projection of the reinforcing protrusion 210.

[0039] In some examples, the extension direction of the floor body 100 refers to any direction parallel to the surface of the largest dimension of the floor body 100. For example, if the floor body 100 is horizontally positioned, its extension direction includes any horizontal direction.

[0040] In some examples, multiple reinforcing structures 200 are set consecutively, meaning that no floor body 100 or other physical structure is set between two adjacent reinforcing structures 200.

[0041] In some examples, the multiple reinforcing protrusions 210 in the reinforcing structure 200 have the same size or structure; in other examples, the multiple reinforcing protrusions 210 in the reinforcing structure 200 have different sizes or structures.

[0042] In some examples, each reinforcing protrusion 210 is arranged adjacent to at least two other reinforcing protrusions 210 along the extension direction of the floor body 100. For example, the floor body 100 includes three reinforcing protrusions 210, which are adjacent to each other in pairs. It should be noted that different reinforcing protrusions 210 in the reinforcing structure 200 may have the same or different numbers of adjacent reinforcing protrusions 210.

[0043] The technical solution provided in this application embodiment includes a vehicle floor comprising a floor body 100 and a reinforcing structure 200. The reinforcing structure 200 is disposed within the reinforcing region 110 of the floor body 100 to increase the structural strength of the vehicle floor.

[0044] Based on this, the reinforcing structure 200 includes multiple reinforcing protrusions 210, which are continuously arranged along the extension direction of the floor body 100 to form a continuous buffering reinforcing structure 200. Each reinforcing protrusion 210 is arranged adjacent to at least two other reinforcing protrusions 210. Each reinforcing protrusion 210 can transmit vibration impact in different directions to the at least two adjacent reinforcing protrusions 210 to effectively disperse vibration energy and improve vibration reduction effect. In addition, the multiple reinforcing protrusions 210 increase the cross-sectional area of ​​the vehicle floor, which can improve the torsional and bending resistance of the vehicle floor and optimize the stiffness of the vehicle floor so as to provide stable support and positioning for the components fixed to the vehicle floor.

[0045] Compared with the strip-shaped reinforcing ribs in related technologies, the vehicle floor of this application is provided with multiple continuous reinforcing protrusions 210, which can effectively buffer vibration impact, improve the rigidity of the vehicle floor, and thus improve the NVH performance of the vehicle.

[0046] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the reinforcing protrusion 210 includes a first surface 211, and the floor body 100 includes a structural surface 120, the structural surface 120 and the first surface 211 being located on the same side of the vehicle floor; the first surface 211 is provided to protrude relative to the floor body 100 in a direction away from the structural surface 120, and at least a portion of the first surface 211 extends along an arc.

[0047] In some examples, the first surface 211 is the convex surface of the reinforcing protrusion 210, and the first surface 211 is convex away from the center surface of the floor body 100.

[0048] In some examples, the entire first surface 211 extends along an arc, and the first surface 211 can be a curved surface, a conical surface, a spherical surface, or an ellipsoidal surface, etc.; in other examples, part of the first surface 211 extends along an arc, and another part extends along a straight line. For example, the outline of the first surface 211 is a frustum shape, and its top surface is a plane.

[0049] The technical solution provided in this application embodiment strengthens the first surface 211 of the protrusion 210 by protruding relative to the floor body 100, and at least a portion of the first surface 211 extends along an arc. The protrusion 210 is configured as an arc-shaped structure to disperse the vibration impact received and improve the impact resistance and vibration reduction performance.

[0050] Reference Figure 4 In some embodiments of this application, the reinforcing protrusion 210 includes a second surface 212, which is recessed relative to the floor body 100 in a direction away from the structural surface 120, and the distance between the second surface 212 and the first surface 211 is uniformly arranged.

[0051] In some examples, the second surface 212 is a concave surface of the reinforcing protrusion 210, the second surface 212 is concave towards the center surface of the floor body 100, and the second surface 212 and the first surface 211 are opposite surfaces of the reinforcing protrusion 210.

[0052] In some examples, the distance between the first surface 211 and the second surface 212 refers to the distance in the direction perpendicular to the first surface 211 and the second surface 212. For example, if both the first surface 211 and the second surface 212 are spherical, then the distance refers to the distance in the radial direction.

[0053] In some examples, the uniform spacing between the first surface 211 and the second surface 212 means that the spacing between multiple reference points on the second surface 212 and the first surface 211 along the corresponding direction is equal or less than a preset threshold. For example, the spacing difference between different reference points is less than 0.1 mm.

[0054] The technical solution provided in this application embodiment strengthens the second surface 212 of the protrusion 210 to be concave relative to the floor body 100, and the distance between the second surface 212 and the first surface 211 is uniformly set so as to strengthen the protrusion 210 to form a plate-like structure, which is convenient for stamping or molding, has strong process adaptability, is easy to process and produce, and the plate-like structure uses less material and is lighter, so as to improve the structural strength and stability while reducing the weight of the front floor.

[0055] Reference Figure 4 , Figure 5 and Figure 6 In some embodiments of this application, a first transition portion 220 is provided between two adjacent reinforcing protrusions 210. The first transition portion 220 includes a third surface 221, which is in contact with the first surface 211. The third surface 221 is recessed relative to the floor body 100 in a direction close to the structural surface 120 to form a drainage groove 222.

[0056] In some examples, the third surface 221 and the first surface 211 are continuously arranged surfaces, and the third surface 221 and the first surface 211 can have an acute angle, an obtuse angle or a right angle transition; or the first surface 211 and the second surface 212 can have a rounded corner or a smooth transition.

[0057] In some examples, the concave direction of the third surface 221 relative to the floor body 100 is opposite to the convex direction of the first surface 211 relative to the floor body 100. For example, the reinforcing protrusion 210 protrudes upward and the third surface 221 is concave downward to facilitate fluid flow.

[0058] It should be noted that the cross-sectional profile of the drainage channel 222 can be a regular or irregular shape such as a triangle, rectangle, semicircle, or trapezoid.

[0059] In some examples, a second transition portion 230 is provided between the floor body 100 and the adjacent reinforcing protrusion 210. The second transition portion 230 and the first transition portion 220 may have the same or different structures and dimensions.

[0060] The technical solution provided in this application embodiment forms a flow channel 222 in the first transition portion 220 between two adjacent reinforcing protrusions 210. The flow channel 222 facilitates the flow of liquid. A large number of flow channels 222 with diverse paths can be formed between multiple reinforcing protrusions 210 in the reinforcing structure 200 to guide the flow of coolant, electrophoretic coating, etc., thus enriching the functionality of the reinforcing mechanism.

[0061] Reference Figure 4 , Figure 6 and Figure 7 In some embodiments of this application, the first surface 211 and the third surface 221 are both arc surfaces. The first surface 211 has a first radial dimension R1, and the third surface 221 has a second radial dimension R2. The ratio of the second radial dimension R2 to the first radial dimension R1 is in the range of 0.2-0.3.

[0062] In some examples, the ratio of the second radial dimension R2 to the first radial dimension R1 is greater than or equal to 0.2 and less than or equal to 0.25, for example, 0.2, 0.21, 0.22, 0.23, 0.24, or 0.25; in other examples, the ratio of the second radial dimension R2 to the first radial dimension R1 is greater than or equal to 0.25 and less than or equal to 0.3, for example, 0.25, 0.26, 0.27, 0.28, 0.29, or 0.3.

[0063] In some examples, the corresponding first radial dimension R1 of the first surface 211 is a radius that is greater than or equal to 32 millimeters (mm) and less than or equal to 35 mm, such as 32 mm, 32.5 mm, 33 mm, 33.5 mm, 34 mm, 34.5 mm, or 35 mm.

[0064] In some examples, adjacent reinforcing protrusions 210 are smoothly transitioned by a rounded corner with a radius of 9 mm. This chamfer design has a dual function: on the one hand, the 9 mm radius transition angle ensures the natural transmission of stress flow and solves the stress concentration problem caused by right-angle connections; on the other hand, the drainage channel 222 with a width W of 8 mm formed by the chamfered area forms an efficient drainage path. Experimental data show that its drainage efficiency is 70% higher than that of the traditional structure.

[0065] It should be noted that the dimensions of the first surface 211 and the third surface 221 mentioned above are merely examples. The first radial dimension R1 corresponding to the first surface 211 can be designed based on the area of ​​the reinforced region 110, the number of reinforcing protrusions 210 required by the reinforced structure 200, and the strength requirements of the vehicle floor, etc. The second radial dimension R2 corresponding to the third surface 221 can be designed based on drainage requirements or the strength requirements of the vehicle floor, etc.

[0066] The technical solution provided in this application embodiment allows for a larger first radial dimension R1, which increases the size of the reinforcing protrusion 210, thus providing better bending and torsional resistance. A larger second radial dimension R2 allows for the formation of a larger drainage channel 222, facilitating liquid passage. Setting the ratio of the second radial dimension R2 to the first radial dimension R1 within a suitable range balances the strength of the reinforcing structure 200 with liquid flowability, meeting the demands of complex operating conditions.

[0067] Reference Figure 5 In some embodiments of this application, the first transition portion 220 extends along a straight line and has a preset size L along its extension direction. The multiple first transition portions 220 corresponding to the same reinforcing protrusion 210 have the same preset size L.

[0068] In some examples, the projected outer contour of the reinforcing protrusion 210 along the vertical projection of the floor body 100 can be a shape such as a triangle, rectangle, rhombus, trapezoid, pentagon or hexagon, and the first transition portion 220 corresponding to the reinforcing protrusion 210 corresponds to the edge of the projected outer contour.

[0069] In some examples, the fact that the preset dimensions L of multiple first transition portions 220 are consistent means that the difference between the preset dimensions L of any two first transition portions 220 is less than or equal to a preset threshold. For example, under the condition that the processing accuracy or measurement accuracy allows, any two preset dimensions L corresponding to the same reinforcing protrusion 210 are less than 0.1 mm.

[0070] In some examples, the central reinforcing protrusion 210 is cross-linked with the six surrounding reinforcing protrusions 210 to form a hexagonal topology. Its planar projection (projection in the direction perpendicular to the floor body 100) presents a regular hexagonal feature with a side length of 20mm. This biomimetic layout significantly improves the isotropic stiffness of the overall structure.

[0071] The technical solution provided in this application embodiment is that the first transition portion 220 extends in a straight line so that the flow resistance of the formed drainage groove 222 is small, which facilitates the flow of liquid; the multiple first transition portions 220 corresponding to the same reinforcing protrusion 210 adopt the same preset size L so that the reinforcing protrusion 210 forms a more regular structure, which facilitates the splicing of multiple reinforcing protrusions 210.

[0072] Reference Figure 2 , Figure 3 and Figure 5 In some embodiments of this application, the plurality of reinforcing protrusions 210 include at least two columns of protrusions arranged sequentially along a first direction X, and each column of protrusions includes at least two reinforcing protrusions 210 arranged sequentially along a second direction Y, wherein the second direction Y has an angle with the first direction X.

[0073] It should be noted that the angle between the first direction X and the second direction Y can be acute, right, or obtuse. In some examples, the first direction X is the length direction of the vehicle, and the second direction Y is the width direction of the vehicle.

[0074] In one example, the reinforcing protrusions 210 include n columns of protrusions, and each column of protrusions includes m reinforcing protrusions 210, thereby forming a honeycomb reinforcing structure 200 composed of m*n reinforcing protrusions 210, where m and n are both positive integers greater than or equal to 2.

[0075] The technical solution provided in this application embodiment is that multiple reinforcing protrusions 210 form a protrusion column, and the protrusion column includes at least two reinforcing protrusions 210 arranged along the second direction Y, and at least two protrusion columns are arranged along the first direction X, so that the multiple reinforcing protrusions 210 form an array structure, the structure is more regular, and it is easier to process and manufacture.

[0076] Reference Figure 2 , Figure 3 and Figure 5 In some embodiments of this application, the reinforcing protrusions 210 in two adjacent protrusion columns are staggered along the second direction Y.

[0077] In some examples, the amount of staggering of the reinforcing protrusions 210 in adjacent columns of protrusions is related to the size of a single reinforcing protrusion 210. For example, multiple reinforcing protrusions 210 in reinforcing structure 200 may employ an arc structure of the same size, with an staggering amount that is half the size of the arc structure.

[0078] In some examples, a 33.5mm radius arc-shaped reinforcing protrusion 210 is used as the basic unit. The coverage area of ​​a single reinforcing protrusion 210 can be adjusted by changing the central angle A. Different central angles A result in different height dimensions H for the reinforcing protrusion 210. Adjusting the central angle A allows for the formation of reinforcing ribs with a height dimension H ranging from 5mm to 10mm. Multiple reinforcing protrusions 210 are arranged in a staggered layout, with adjacent columns of protrusions 210 offset by a 17.3mm misalignment to form a half-phase shift. This design not only enhances the continuity of the reinforcing structure 200 but also constructs an n-layer staggered protective network in the longitudinal dimension, improving vibration resistance and reinforcement effects.

[0079] The technical solution provided in this application embodiment sets the reinforcing protrusions 210 in the protrusion column as an interlaced structure so that a single reinforcing protrusion 210 can be adjacent to more reinforcing protrusions 210, forming a more dispersed vibration energy transmission path, thereby improving the vibration resistance of the reinforcing structure 200.

[0080] Reference Figure 2 and Figure 3 In some embodiments of this application, the vehicle floor includes at least two reinforcing regions 110, and / or the vehicle floor includes at least two floor bodies 100; and each reinforcing region 110 of the floor body 100 is provided with a reinforcing structure 200.

[0081] In some examples, the vehicle floor includes a single floor body 100, which has one or more reinforcing regions 110, and the different reinforcing regions 110 have reinforcing structures 200 with the same or different structures.

[0082] In some examples, the vehicle floor includes one or more floor bodies 100, each floor body 100 having a reinforcing region 110 with a reinforcing structure 200. The reinforcing structures 200 of different floor bodies 100 may have the same or different structures.

[0083] For example, the vehicle floor includes Figure 2 The first floor shown and Figure 3 The second floor shown is arranged along the width direction of the vehicle. For example, the first floor is the left front floor and the second floor is the right front floor. The first floor and the second floor are respectively provided with honeycomb-shaped reinforcing structures 200.

[0084] The technical solution provided in this application embodiment includes a vehicle floor comprising at least two reinforcing regions 110, and each reinforcing region 110 is provided with a reinforcing structure 200. The structural strength of the vehicle floor can be improved from multiple regions. By superimposing the performance of multiple reinforcing structures 200, the vibration resistance and structural stiffness of the vehicle floor can be further improved. By providing reinforcing structures 200 on multiple floor bodies 100 of the vehicle floor, corresponding strength improvements can be provided for different floor bodies 100.

[0085] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the vehicle includes a body 300 and a vehicle floor, which is connected to the body 300.

[0086] In some examples, the vehicle body 300 includes a floor frame comprising crossbeams and longitudinal beams arranged in a cross configuration, with the vehicle floor laid over the crossbeams and longitudinal beams.

[0087] In some examples, the vehicle body 300 also includes a seat that is attached to the floor of the vehicle body 300 and supported by the floor of the vehicle body 300.

[0088] The technical solution provided in this application embodiment includes a vehicle floor, and the reinforced area 110 of the vehicle floor is provided with a plurality of continuous reinforcing protrusions 210, which can effectively buffer vibration and impact, improve the rigidity of the vehicle floor, and thus improve the NVH performance of the vehicle.

[0089] In one embodiment of this application, the vehicle floor includes a first floor and a second floor. The first floor and the second floor are respectively provided with a reinforcing structure 200. The reinforcing structure 200 includes a plurality of reinforcing protrusions 210 forming a honeycomb structure. The first surface 211 and the second surface 212 of the reinforcing protrusions 210 are arc surfaces. The edges of the reinforcing protrusions 210 are regular hexagonal structures. A single reinforcing protrusion 210 can be adjacent to six or fewer reinforcing protrusions 210. The plurality of reinforcing protrusions 210 form a plurality of sequentially arranged protrusion columns. The protrusion columns include a plurality of sequentially arranged reinforcing protrusions 210. The plurality of reinforcing protrusions 210 in adjacent protrusion columns are staggered. The stagger size is the radius corresponding to a single reinforcing protrusion 210. For example, if the diameter corresponding to a single reinforcing protrusion 210 is 33.5 mm, then the stagger size is 17.3 mm. A drainage groove 222 is formed between two adjacent reinforcing protrusions 210. The cross-section of the drainage groove 222 is set to be arc-shaped, and the radius of the drainage groove 222 is set to be 9 mm.

[0090] The vehicle floor and vehicle of this application embodiment employ a honeycomb hexagonal reinforcement structure 200 arranged in an arc shape. The reinforcement structure 200 includes multiple closely arranged hexagonal reinforcing protrusions 210, which can improve the rigidity of the vehicle floor and reduce vibration. The honeycomb reinforcement structure 200 can effectively disperse vibration energy, solving the problem of vibration and resonance in the front floor assembly under complex dynamic loads, improving road noise transmission from the vehicle floor, and enhancing the overall NVH performance of the vehicle. The honeycomb reinforcement structure 200 also has good torsional and bending resistance to optimize the rigidity of areas such as oil pipe fixing. Adjacent reinforcing protrusions 210 form guiding drainage channels 222, and the drainage channels 222 between multiple reinforcing protrusions 210 converge to form a continuous and reasonable channel path, which facilitates the flow of liquid electrophoretic coating along the drainage channels 222, has good electrophoretic coating function, and also facilitates the discharge of coolant and other substances, and facilitates the process. This reinforcing structure 200 effectively solves multiple technical problems such as floor vibration, road noise control, oil pipe path stability and guiding drainage while improving the mechanical performance of the vehicle floor.

[0091] Reference Figure 8 The figures show the frequency response function (FRF) curves of three different vehicle floor structures. Curve C3 shows the frequency response function curve of the honeycomb reinforced structure 200 of this application, while curves C1 and C2 are the frequency response function curves of the floor in the related art. The comparison shows that the vehicle floor of the honeycomb reinforced structure 200 significantly reduces the vibration response in the key frequency band and the amplitude is significantly reduced compared to other floors.
