[0038] In order to more clearly understand the above-mentioned objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0039] Many specific details are set forth in the following description in order to provide a thorough understanding of the present disclosure, but the present disclosure may be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

[0040] Embodiment 1

[0041] As Figures 1-4 shown, this embodiment provides a vehicle floor structure, which includes a floor body 1 and a patch plate 2. Cross beams 11 and longitudinal beams 12 are formed on the floor body 1, and the cross beams 11 and the longitudinal beams 12 are arranged in a crisscross manner.

[0042] For the vehicle floor structure provided in this embodiment, cross beams 11 and longitudinal beams 12 are formed on the floor body 1. That is to say, the floor body 1 is an integral plate structure, and the cross beams 11 and the longitudinal beams 12 are directly formed on the floor body 1. That is, the cross beams 11 and the longitudinal beams 12 are directly formed on the floor body 1, and the separate structures of the cross beams 11 and the longitudinal beams 12 are cancelled. Therefore, there will be no welds or riveting parts connecting the cross beams 11, the longitudinal beams 12 and the floor body 1. Compared with the prior art in which the floor body 1, the cross beams 11, the longitudinal beams 12, etc. are connected by splicing, the number of splices is reduced, the assembly process is faster, and the overall weight can also be reduced to a certain extent compared with the prior art.

[0043] Specifically, the floor body 1 can be an integral plate structure, and the cross beams 11 and the longitudinal beams 12 on the floor body 1 can be formed by stamping the integral plate structure through a high-pressure die-casting process, so as to form the protruding cross beams 11 and longitudinal beams 12 on the floor body 1.

[0044] This embodiment takes the floor body 1 as the front floor as an example for illustration. In other embodiments, it can also be flexibly applied to other positions such as the rear floor. Among them, the cross beams 11 can specifically be the front cross beam 11 and the middle cross beam 11 on the front floor. In other embodiments, the front cross beam 11 can also be designed separately, or the middle cross beam 11 can be designed separately.

[0045] Furthermore, a patch panel 2 is provided at the position of the floor body 1 where the cross beam 11 is formed, and the patch panel 2 is press-fitted and connected to the floor body 1.

[0046] Since the cross beam 11 on the vehicle floor plays an important role in ensuring the torsional stiffness of the vehicle frame and bearing longitudinal loads, and is a key component for supporting the vehicle, it is required to protect the occupants in the vehicle during a collision. Therefore, the position of the cross beam 11 on the vehicle floor needs to ensure sufficient structural strength and stiffness. Only forming the cross beam 11 structure through a part of the floor body 1 cannot meet the structural performance requirements of the cross beam 11.

[0047] In this embodiment, the patch panel 2 is used to be arranged at the position of the floor body 1 where the cross beam 11 is formed, in order to enhance the structure at the position of the cross beam 11. Since the cross beam 11 is formed by stamping on the floor body 1, the structural strength at the cross beam 11 is weak and may not meet the required strength and stiffness of the floor cross beam 11. Therefore, by covering the patch panel 2 at the position of the cross beam 11 of the floor body 1, the structure at the position where the cross beam 11 is located can be enhanced by superimposing the patch panel 2, so that on the basis of forming the cross beam 11 by stamping the floor body 1, the floor body 1 and the patch panel 2 jointly bear the load demand at the cross beam 11 to ensure sufficient structural performance.

[0048] The vehicle floor structure provided in this embodiment includes a floor body 1 and a patch panel 2, so that the cross beams 11 and longitudinal beams 12 are formed on the floor body 1 in an interlaced manner. The patch panel 2 is covered at the position of the floor body 1 where the cross beam 11 is formed, and the patch panel 2 is press-fitted with the floor body 1 to form an integral structure. Such a setting enables the cross beams 11 and longitudinal beams 12 to be directly formed through the floor body 1, that is, the separate cross beam 11 and longitudinal beam 12 structures are cancelled. Therefore, there will be no welds or riveted parts connecting the cross beam 11, longitudinal beam 12 and the floor body 1. Compared with the prior art in which the separate floor body 1, cross beam 11, longitudinal beam 12, etc. are connected by splicing, the number of splices is reduced, the assembly process is faster, and the vehicle floor structure is lightened. Moreover, the patch panel 2 can enhance the structure at the position of the cross beam 11, so that the floor body 1 and the patch panel 2 jointly bear the load demand at the cross beam 11 to ensure that the vehicle floor has sufficient structural performance.

[0049] In some embodiments, the patch panel 2 is connected to the floor body 1 by hot pressing, so that the patch panel 2 completely adheres to the surface of the cross beam 11. This setting can achieve a more uniform and tight joint between the patch panel 2 and the floor body 1, with a higher connection tightness between the patch panel 2 and the floor body 1. Moreover, it can improve the mechanical properties such as the strength, hardness, and toughness of the overall structure through hot pressing, thereby further enhancing the structural strength of the vehicle floor structure at the position of the cross beam 11, and further ensuring that the cross beam 11 has sufficient structural performance. Compared with the traditional sheet metal welding process, a single hot stamping process can effectively reduce the lapped edges and connection points, improve the sealing performance of the floor structure, and achieve weight reduction and lightweighting.

[0050] Since the cross beam 11 of the traditional vehicle floor structure is designed and produced separately to ensure its sufficient structural performance, the setting of the patch panel 2 enables the vehicle floor structure provided in this embodiment to have a collision performance comparable to that of the traditional vehicle floor structure, so as to ensure the protection of the battery pack and the passenger compartment under different working conditions. On this basis, the vehicle floor structure provided in this embodiment can significantly reduce the tooling and die costs, simplify the OEM assembly line, save inputs such as equipment, site, and logistics. By integrating the patch panel 2 onto the integrated floor body 1, the integration of manufacturing is achieved, saving manufacturing costs and improving manufacturing efficiency. At the same time, the vehicle weight can be reduced to achieve the lightweight goal.

[0051] In some embodiments, the floor body 1 can use a metal material with relatively high strength, such as the 0.8mm thick Usibor1500 hot forming material. For the patch panel 2 structure provided on the cross beam 11, since it is a key side impact force transmission area, the patch panel 2 structure provided on the cross beam 11 can, for example, use the 1mm thick Usibor2000 hot forming material. Of course, in other embodiments, the strength of the patch panel 2 can also be flexibly adjusted according to the actual working conditions and different use areas of the patch panel 2 on the floor body 1.

[0052] In some embodiments, the number of cross beams 11 is multiple, and all cross beams 11 are arranged at intervals along the longitudinal direction of the floor body 1. The number of patch panels 2 is multiple, and each cross beam 11 is correspondingly covered with a patch panel 2. This setting can achieve targeted structural strengthening of the patch panel 2 and ensure that each cross beam 11 has sufficient load-bearing performance.

[0053] In other embodiments, the patch panel 2 can also be a whole plate structure covering the floor body 1, and it is ensured that the positions of all cross beams 11 can be covered. This not only ensures the structural enhancement of the cross beam 11, but also enhances the structures of other parts of the floor body 1 except the cross beam 11, thereby further improving the strength performance of the entire vehicle floor structure.

[0054] In some embodiments, a sled plate 13 is further formed on one side of the floor body 1. At least part of the sled plate 13 is covered with a patch plate 2, and the patch plate 2 covered on the sled plate 13 is press-fitted and connected to the floor body 1.

[0055] For a vehicle, the types of collisions include frontal collision, side collision, rear-end collision, etc. Among them, the frontal collision causes the greatest harm to personnel. For a vehicle, its body structure is required to absorb collision energy and protect the occupants in the occupant compartment from being injured. Therefore, strengthening beams are arranged on the floor structure of the vehicle to transmit the collision force. Such a beam with a relatively strong structure is called the sled plate 13 structure. The sled plate 13 structure usually has an arc transition to lap with the sill beam, so as to protect the area in front of the front mounting cross beam 11 of the seat during a collision.

[0056] The floor body 1 provided in this embodiment forms a sled plate 13 on one side of the floor body 1, thereby canceling the separate sled plate 13 structure. Therefore, the welds or rivets connecting the sled plate 13 and the bottom plate body can also be canceled. Compared with the prior art method of connecting and forming a separate sled plate 13 and the bottom plate body by splicing, the number of splices is reduced, the assembly process is faster, and the overall weight of the vehicle floor structure can also be reduced to a certain extent compared with the prior art.

[0057] On this basis, the patch plate 2 is covered on at least part of the sled plate 13, so as to strengthen the structure at the position of the sled plate 13. Thus, on the basis of forming the sled plate 13 by stamping the floor body 1, the sled plate 13 and the patch plate 2 provided on the sled plate 13 jointly bear the load-bearing requirements at the position of the sled plate 13 to ensure sufficient structural performance.

[0058] Specifically, the floor body 1 is an integral plate structure, and the sled plate 13 is formed by stamping the integral plate structure through a high-pressure die-casting process, so as to form an extended sled plate 13 structure on the floor body 1. And for the patch plate 2 structure provided on the sled plate 13, since it is a key frontal collision force transmission area, the patch plate 2 structure provided on the sled plate 13 can, for example, use a 1-mm-thick Usibor1500 hot-forming material.

[0059] In some embodiments, the number of sled plates 13 is multiple, and a patch plate 2 is correspondingly provided on each sled plate 13. With such a setting, targeted structural strengthening of the patch plate 2 can be achieved, and sufficient load-bearing performance can be ensured at each position of the sled plate 13.

[0060] Among them, at least part of the sled board 13 is covered with a patch board 2. It can be understood that the patch board 2 provided on one of the sled boards 13 does not completely cover the sled board 13, that is to say, the patch board 2 only covers a part of the sled board 13. This setting, on the one hand, minimizes the material usage on the basis of ensuring sufficient structural strength at the sled board 13, so as to further control the weight of the floor. On the other hand, it is convenient to set connection parts and other structures between the sled board 13 and other structures, such as between the sled board 13 and the cross beam 11.

[0061] In this embodiment, the patch board 2 covered on the cross beam 11 corresponds to the extension length and the outer contour shape of the cross beam 11, and the patch board 2 covered on the sled board 13 corresponds to the extension length and the outer contour shape of the sled board 13. That is to say, there are at least two types of patch boards 2 corresponding to the cross beam 11 and the sled board 13 respectively. And the number of the patch boards 2 can be specifically determined according to the number of the cross beams 11 and the sled boards 13 on the floor body 1.

[0062] Similarly, in other embodiments, the patch board 2 can also be a whole board structure covered on the floor body 1, and it is ensured that all the positions of the sled boards 13 can be covered, or while covering the positions of the sled boards 13, the positions of the cross beams 11 are also covered. This not only ensures the structural enhancement of the sled boards 13, or the sled boards 13 and the cross beams 11 together, but also enhances the other part structures of the floor body 1 except the cross beams 11 and the sled boards 13, thereby further improving the strength performance of the entire vehicle floor structure.

[0063] In some embodiments, the patch board 2 includes a clamping plate 21 and an extension edge 22. A receiving groove for receiving the cross beam 11 is formed on the clamping plate 21. The extension edge 22 is arranged around the edge of the receiving groove and extends in a direction away from the receiving groove. The clamping plate 21 is clamped on the cross beam 11, and the extension edge 22 is attached to the part of the floor body 1 located on the outer peripheral side of the cross beam 11. The patch board 2 is pressed against the floor body 1 through the extension edge 22 to form an integral structure.

[0064] The patch plate 2 is arranged as the buckle plate 21 and the extension edge 22. On the one hand, it can enable the patch plate 2 to wrap the entire cross beam 11 and be arranged in accordance with the arrangement mode of the cross beam 11. In this way, when the acting force is transmitted to the position of the cross beam 11, the patch plate 2 and the cross beam 11 can have basically the same stress distribution, so as to ensure that the overall stress distribution requirements of the vehicle floor structure will not be affected after the patch plate 2 is set. On the other hand, by making the extension edge 22 fit with the floor body 1 along the outer peripheral side of the cross beam 11, while ensuring the protection and strengthening effect of the patch plate 2 on the cross beam 11, it also makes the patch plate 2 and the floor body 1 have a relatively uniform joint effect, ensuring the connection tightness between the patch plate 2 and the floor body 1.

[0065] In some embodiments, the buckle plate 21 and the cross beam 11 are connected by welding. Such an arrangement can further ensure the connection firmness between the buckle plate 21 and the cross beam 11. Specifically, when implementing, electric welding can be used to perform multi-point welding along the extension direction of the cross beam 11 and the buckle plate 21, so as to minimize the number of welding points as much as possible.

[0066] In some embodiments, the joint between the extension edge 22 and the floor body 1 is adhesively connected. Such an arrangement can further ensure the connection tightness between the extension edge 22 and the floor body 1.

[0067] In some embodiments, the wall of the accommodation groove fits with the surface of the cross beam 11. Such an arrangement can enable the patch plate 2 and the cross beam 11 to have a better fitting effect, so that the patch plate 2 and the cross beam 11 cooperate together to better bear the acting force in the direction of the cross beam 11.

[0068] In some embodiments, the vehicle floor structure further includes a joint connector 3. At least part of the joint connector 3 is arranged on the patch plate 2 covering the cross beam 11, and at least part of the joint connector 3 is used to connect the cross beam 11 with the vehicle body sill. The arrangement of the joint connector 3 can facilitate the connection between the position of the cross beam 11 and the vehicle body sill. For example, when the vehicle floor structure is the vehicle front floor, joint connectors 3 are arranged on both the cross beam 11 in the middle of the front floor and the cross beam 11 in front of the front floor to realize the connection of the entire floor with the vehicle body sill.

[0069] Specifically, the number of the joint connectors 3 is at least two. Two joint connectors 3 are correspondingly arranged on each patch plate 2, and the two joint connectors 3 are respectively arranged at both ends of a patch plate 2. Since both ends of the cross beam 11 structure need to be correspondingly connected to the vehicle body sills on both sides of the vehicle, each cross beam 11 is connected to the vehicle body sills on both sides through two joint connectors 3 to ensure the assembly effect between the vehicle floor structure and the vehicle body sill.

[0070] In some embodiments, the joint connector 3 is press-fitted with the patch panel 2 to form an integral structure. Press-fitting the joint connector 3 and the patch panel 2 to form an integral structure enables a more uniform and tight bond between the joint connector 3 and the patch panel 2, ensuring sufficient structural strength at the joint connector 3. At the same time, compared with the traditional welding process, the sealing performance of the connection can also be improved.

[0071] In other embodiments, the joint connector 3 and the patch panel 2 can also be connected by welding. Alternatively, after forming an integral structure by press-fitting, electric welding can be performed at multiple positions to further ensure the connection effect and structural strength.

[0072] In some embodiments, the joint connector 3 includes a mounting plate 31 and a lapping edge 32. The mounting plate 31 is buckled on the patch panel 2, and the lapping edge 32 is disposed at the edge of the mounting plate 31 and extends in a direction away from the mounting plate 31. The lapping edge 32 is used to connect with the vehicle body sill. This setting enables a better fitting effect between the joint connector 3 and the patch panel 2, and at the same time facilitates the connection with the vehicle body sill through the lapping edge 32.

[0073] In specific implementation, since the joint connector 3 is disposed at the end of the patch panel 2, the lapping edge 32 is disposed at one side edge of the mounting plate 31 facing the outside of the floor to facilitate the corresponding connection with the vehicle body sills located on both sides of the floor body 1. And the lapping edge 32 can be circumferentially arranged along the outer edge of the mounting plate 31.

[0074] See Figure 4 As shown, in some embodiments, at least one end of the joint connector 3 is connected to the patch panel 2 covering the sled plate 13, and the other end of the joint connector 3 is connected to the patch panel 2 covering the cross beam 11. Through this joint connector 3, not only is there sufficient connection position on the vehicle floor structure to connect with other structures of the vehicle, but also the patch panel 2 on the sled plate 13 is connected and joined with the patch panel 2 on the cross beam 11, thereby further enhancing the strength of the entire vehicle floor structure.

[0075] In specific implementation, the joint connector 3 can be disposed between some of the sled plates 13 and the cross beams 11, and can be flexibly adjusted according to the configuration of the mounting points on the vehicle. And the sled plate 13 is connected to the cross beam 11 closest to it, which is usually the front cross beam 11 of the front floor structure.

[0076] See Figure 4 As shown, in some embodiments, the joint connector 3 can also be disposed between two adjacent cross beams 11 to further add connection points to the vehicle floor structure.

[0077] In some embodiments, reinforcing ribs 14 are further formed on the floor body 1. The number of the reinforcing ribs 14 is multiple, and all the reinforcing ribs 14 are arranged at intervals along the transverse direction and / or the longitudinal direction of the floor body 1. The arrangement of the reinforcing ribs 14 can further ensure the structural strength of the vehicle floor structure. Specifically, the reinforcing ribs 14 can be arranged in a combined manner of transverse reinforcing ribs 14 and longitudinal reinforcing ribs 14 to achieve a better stress distribution effect.

[0078] For the arrangement of the reinforcing ribs 14, the grouting path where the reinforcing ribs 14 need to be arranged can be obtained through CAE optimization, so as to efficiently improve the overall performance of the floor structure. Among them, CAE optimization means using CAE software (Computer-Aided Engineering Software) to perform structural analysis, vibration analysis, etc. on the vehicle floor. CAE software can utilize computer technology and numerical simulation methods to simulate and predict the behaviors of different engineering systems, so as to discover potential problems in advance and take corresponding measures. For example, in automotive engineering, engineers can use CAE software to simulate the collision, fatigue, and vibration of the vehicle to obtain the stress defect positions of the vehicle, and then optimize the defect positions to ensure the safety performance of the vehicle.
