[0037] The present application provides a vehicle floor.

[0038] In the embodiments of the present application, please refer to Figures 1 to 7 The vehicle floor is applied to a vehicle, the vehicle includes a vehicle-mounted power management module 900a and a storage battery 900b, and the vehicle floor includes a floor body 100, a longitudinal beam assembly, a reinforcing piece and a mounting piece. The longitudinal beam assembly includes a first longitudinal beam 200 and a second longitudinal beam 300 fixed to opposite sides of the floor body 100, respectively. The reinforcing piece is arranged below the floor body 100 and fixed to the longitudinal beam assembly. The mounting piece is arranged on the lower side of the floor body 100 and connected to the reinforcing piece, and the mounting piece is used for mounting at least one of the vehicle-mounted power management module 900a and the storage battery 900b.

[0039] The technical scheme of the present application transmits the force of the vehicle power management module 900a and the battery 900b to the longitudinal beam assembly by mounting the vehicle power management module 900a and the battery 900b on the reinforcing member, which is arranged below the floor body 100 and fixed on the longitudinal beam assembly, so that the stiffness and strength of the vehicle floor are sufficient to support the vehicle power management module 900a and the battery 900b. Compared with directly placing the vehicle power management module 900a and the battery 900b on the floor body 100 and supporting them by the reinforcing member arranged below the floor body 100, the installation height of the vehicle power management module 900a and the battery 900b can be effectively reduced, and the space occupied by the vehicle power management module 900a and the battery 900b in the rear trunk can be reduced, so that the space volume of the rear trunk of the hybrid vehicle is ensured, and the market competitiveness of the hybrid vehicle type of the vehicle floor using the present application is improved.

[0040] In the present embodiment, the installation height of the vehicle power management module 900a can be reduced, or the installation height of the battery 900b can be reduced, or the installation height of the vehicle power management module 900a and the battery 900b can be reduced.

[0041] Under the premise of meeting the support stiffness and strength, the reinforcing member can be the original load-bearing structure of the vehicle frame, such as the sub-frame 400, the rear cross beam, etc., or a newly added load-bearing structure, such as a newly added cross beam. As for the installation height of the vehicle power management module 900a and the battery 900b, the reinforcing member is arranged below the floor body 100 in the present embodiment, and the vehicle power management module 900a and the battery 900b are fixedly mounted on the reinforcing member through the mounting member on the reinforcing member. At this time, the floor body 100 can be provided with a recess, and the vehicle power management module 900a and the battery 900b are mounted in the recess, and the reinforcing member and the mounting member are arranged below the recess to provide support force for the floor body 100, or the floor body 100 can be provided with an avoiding opening, and the vehicle power management module 900a and the battery 900b are directly mounted on the reinforcing member below the avoiding opening. At this time, a reinforcing structure is arranged below the floor body 100 and adjacent to the avoiding opening to reinforce the avoiding opening, so that the modal performance of the avoiding opening can be improved, and the vibration mode amplitude of the avoiding opening can be effectively reduced.

[0042] In an embodiment, please refer to Figures 1 to 7The reinforcing member includes a subframe 400 fixed to the longitudinal beam assembly, and the mounting member includes a first mounting member 600 arranged on the subframe 400 and used for mounting the vehicle power management module 900a. In this way, the reinforcing member of the present embodiment utilizes the existing subframe 400, and the vehicle power management module 900a is directly fixed to the subframe 400 through the first mounting member 600, so that the gap between the subframe 400 and the floor body 100 can be fully utilized, thereby reducing the mounting height of the vehicle power management module 900a. In order to adapt to the structure of the original subframe 400, the first mounting member 600 is designed in reference to the original shape on the subframe 400 in the present embodiment, so that the first mounting member 600 can stably mount the vehicle power management module 900a. Of course, in other embodiments, a cross beam can be newly installed below the first longitudinal beam 200 and the second longitudinal beam 300, and the vehicle power management module 900a is mounted on the cross beam, thereby reducing the mounting height of the vehicle power management module 900a.

[0043] Specifically, in the present embodiment, please continue to refer to Figures 1 to 7 The second reinforcing rib 610 is arranged on the first mounting member 600 to improve the structural strength of the first mounting member 600, so as to guarantee the supporting effect of the first mounting member 600 on the vehicle power management module 900a and meet the rigidity and strength requirements of supporting the vehicle power management module 900a. On the other hand, since the first mounting member 600 is adapted to the shape of the subframe 400, there are inevitably some structures on the first mounting member 600 that are not subjected to force. Therefore, the first mounting member 600 is provided with a weight-reducing hole 620 to reduce the weight of the first mounting member 600 while guaranteeing the supporting effect of the first mounting member 600 on the vehicle power management module, thereby reducing the material usage of the first mounting member 600 to reduce the production cost.

[0044] As for the design of the floor body 100, please refer to Figures 1 to 7 The floor body 100 is provided with an access hole 110 corresponding to the subframe 400, which is used for avoiding the vehicle power management module 900a. It should be noted that the weight of the vehicle power management module 900a is generally large, and the vehicle power management module 900a is directly mounted on the subframe 400 through the first mounting member 600. Since the subframe 400 is connected with the longitudinal beam assembly, the load bearing requirement can be effectively met, and when the vehicle power management module 900a needs to be repaired, the vehicle power management module 900a can be disassembled through the access hole 110, thereby guaranteeing the convenience of repair. Of course, in other embodiments, a mounting groove can be concavely arranged on the floor body 100, and the vehicle power management module 900a is mounted in the mounting groove, and the mounting groove is fixed to the first mounting member 600 on the subframe 400 below.

[0045] As for the influence of the access hole 110 on the strength of the floor body 100, in the embodiment, please continue to refer to Figures 1 to 7 The reinforcing member further comprises a reinforcing cross beam 500 fixed to the floor body 100 and extending along the edge of the access hole 110, and the two ends of the reinforcing cross beam 500 are connected to the first longitudinal beam 200 and the second longitudinal beam 300, respectively. In this way, when the edge of the access hole 110 is subjected to an external force, the reinforcing cross beam 500 will form a support at the edge of the access hole 110 and transmit the external force to the first longitudinal beam 200 and the second longitudinal beam 300, thereby effectively suppressing the local modal of the access hole 110. Without loss of generality, the structural strength of the reinforcing cross beam 500 is greater than that of the floor body 100 at the access hole 110, thereby ensuring the stability of the edge of the access hole 110, avoiding vibration deformation of the floor body 100, and reducing the noise impact of the floor modal shape on the vehicle interior. Of course, the reinforcing cross beam 500 intersects with the first longitudinal beam 200 and the second longitudinal beam 300, respectively, and a secondary cross beam is further arranged at the edge of the access hole 110 parallel to the first longitudinal beam 200 and the second longitudinal beam 300 to further ensure the rigidity and strength of the access hole 110.

[0046] As for the newly added reinforcing cross beam 500, under the premise of ensuring its structural strength, the embodiment also takes into account the difficulty of processing the reinforcing cross beam 500. In an embodiment, please refer to Figures 1 to 7 The reinforcing cross beam 500 comprises a cross beam body 510 and a cross beam joint 520 connected to each other, the cross beam joint 520 is connected to the first longitudinal beam 200, and the end of the cross beam body 510 away from the cross beam joint 520 is connected to the second longitudinal beam 300, and the cross beam body 510 and the cross beam joint 520 are independently formed and then connected to each other. It should be noted that the access hole 110 is arranged adjacent to the first longitudinal beam 200, the cross beam body 510 extends along the edge of the access hole 110, and a plurality of cross beams are originally arranged between the first longitudinal beam 200 and the second longitudinal beam 300. The cross beam body 510 can be made by using the original cross beam mold, so that only the mold of the cross beam joint 520 needs to be designed, which not only can reduce the development cost, but also can set the shape of the cross beam joint 520 to be more convenient for connection with the first longitudinal beam 200. Of course, in other embodiments, the reinforcing cross beam 500 can be integrally formed, and the two ends of the reinforcing cross beam 500 can also be provided with cross beam joints 520.

[0047] The cross beam joint 520 can be lapped below the cross beam body 510, or the cross beam body 510 can be lapped below the cross beam joint 520. In addition, the connection between the cross beam joint 520 and the first longitudinal beam 200 can be provided with a plurality of lapping surfaces, and the plurality of lapping surfaces can be lapped with the side and bottom of the first longitudinal beam 200, respectively, so as to form a better force transmission loop, so that the force of the vehicle floor is more uniform, and the vehicle floor modal is effectively improved and the vibration mode amplitude of the vehicle floor is reduced.

[0048] It should be noted that the coil spring (not shown in the figure) and the subframe 400 are adjacent to the mounting point of the cross beam assembly and the mounting point of the cross beam 500, and the new force loop formed by the cross beam 500 and the first longitudinal beam 200 and the second longitudinal beam 300 further improves the dynamic stiffness of the mounting point of the subframe 400 and the mounting point of the coil spring.

[0049] Further, in the present embodiment, please refer to Figure 3 The cross beam 500 is provided with a connecting flange 530, and is fixedly connected to the floor body 100 through the connecting flange 530. The connecting flange 530 is provided with a first reinforcing rib 531. Without loss of generality, the connecting flange 530 is adjacent to the edge of the access hole 110. In this way, the connecting flange 530 is arranged to increase the overlapping area of the cross beam 500 and the floor body 100, thereby improving the support force of the cross beam 500 on the floor body 100 and more effectively improving the modal performance of the access hole 110. At the same time, the first reinforcing rib 531 is arranged on the connecting flange 530 to reduce the possibility of stress deformation of the connecting flange 530. Of course, in other embodiments, the connecting flange 530 can be arranged as a discontinuous overlapping surface, or a support member can be arranged on the side of the connecting flange 530 away from the floor body 100, which is inclined to connect the main stem of the cross beam 500.

[0050] For the battery 900b, in an embodiment, the mounting member includes a second mounting member 700 arranged on the floor body 100 and used for mounting the battery 900b. It should be noted that the weight of the battery 900b is smaller than that of the on-board power management module 900a. The floor body 100 can be provided with a small avoiding hole, and the second mounting member 700 is fixed to the avoiding hole in a tray shape, and the edge of the second mounting member 700 is overlapped with the edge of the avoiding hole to effectively support the battery 900b. In this way, the installation height of the battery 900b can be reduced by lowering the installation position of the second mounting member 700. Of course, in other embodiments, a groove can be arranged on the floor body 100, and the battery 900b is directly mounted in the groove. The second mounting member 700 is arranged below the groove and connected with the reinforcing member to transmit the gravity of the battery 900b.

[0051] It can be understood that the battery 900b needs to be electrically connected with the on-board power management module 900a, that is, the battery 900b and the on-board power management module 900a need to be installed as close as possible on the floor of the vehicle. Since the on-board power management module 900a is arranged adjacent to the first longitudinal beam 200, in the present embodiment, please refer to Figures 1 to 7The second mounting member 700 is connected to the second longitudinal beam 300. One end of the reinforcing cross beam 500 is connected to the second longitudinal beam 300 through the second mounting member 700, and the other end is connected to the first longitudinal beam 200. It should be noted that the second mounting member 700 needs to have a relatively large structural strength to support the storage battery. Therefore, the mounting position of the reinforcing cross beam 500 is avoided from the second mounting member 700. In this way, the mounting position of the second mounting member 700 can be arranged flexibly, and the structural strength of the second mounting member 700 can be effectively utilized to support the access hole 110. Thus, the material usage of the reinforcing cross beam 500 is reduced, and the development cost is reduced. In addition, the reinforcing cross beam 500 can improve the structural strength of the second mounting member 700, effectively suppress the modal shape of the floor body 100, and reduce the noise influence of the modal shape of the floor body 100 on the vehicle interior. Of course, in other embodiments, the two ends of the reinforcing cross beam 500 can be directly connected to the second longitudinal beam 300 and the first longitudinal beam 200.

[0052] In an embodiment, in the present embodiment, please refer to Figures 1 to 7 The reinforcing member further includes a bridging frame 800. The second mounting member 700 is arranged adjacent to the second longitudinal beam 300, and the two ends of the bridging frame 800 are connected to the second mounting member 700 and the second longitudinal beam 300, respectively. In this way, the storage battery 900b and the vehicle-mounted power management module 900a are arranged adjacent to each other while leaving a certain gap, so that the shape of the second mounting member 700 is better adapted to the storage battery 900b, and the storage battery 900b is prevented from shaking. Without loss of generality, the bridging frame 800 is arranged at the two ends of the side of the second mounting member 700 adjacent to the second longitudinal beam 300. In this way, the stress of the second mounting member 700 can be better balanced. Of course, in other embodiments, the second mounting member 700 can be directly connected to the second longitudinal beam 300.

[0053] It should be noted that the mounting points of the coil spring and the subframe 400 adjacent to the mounting points of the bridging frame 800 and the second longitudinal beam 300. In this way, the new stress loop formed by the bridging frame 800, the second mounting member 700 and the second longitudinal beam 300 further improves the dynamic stiffness of the mounting points of the subframe 400 and the coil spring.

[0054] Specifically, in the present embodiment, please continue to refer to Figures 1 to 7The two ends of the lapping frame 800 are provided with a plurality of lapping surfaces 810, which are respectively lapped to the second mounting member 700 and the second longitudinal beam 300 through the plurality of lapping surfaces 810. In this way, the plurality of lapping surfaces 810 at one end of the lapping frame 800 are respectively lapped to the side and bottom of the first longitudinal beam 200, and the plurality of lapping surfaces 810 at the other end are respectively lapped to the side and bottom of the second mounting member 700, so as to form a better force transmission loop between the second longitudinal beam 300 and the second mounting member 700, to make the force transmission between the second mounting member 700 and the floor body 100 more uniform, effectively improve the floor mode and reduce the floor mode amplitude, and further strengthen the structural strength of the second mounting member 700.

[0055] Further, in the embodiment, the cross beam joint 520, the cross beam body 510, the second mounting member 700, and the lapping frame 800 are sequentially connected to form a cross beam assembly of the first longitudinal beam 200 and the second longitudinal beam 300, wherein the cross beam body 510 extends along the edge of the access hole 110, and the connecting flange 530 on the side of the reinforcing cross beam 500 facing the access hole 110 directly abuts the edge of the access hole 110.

[0056] When the vehicle-mounted power management module 900a is working, it needs to be cooled and current output. Therefore, the vehicle is provided with a cooling pipeline 900c and a power line 900d, and the vehicle-mounted power management module 900a is connected to the cooling pipeline 900c and the power line 900d. The cooling pipeline 900c and the power line 900d need to be installed with supports for positioning and installation. In an embodiment, please refer to Figures 1 to 7 The first mounting member 600 is also used for mounting and fixing the cooling pipeline 900c and the power line 900d. In this way, the vehicle-mounted power management module 900a, the cooling pipeline 900c, and the power line 900d are all mounted on the first mounting member 600, not only the vehicle-mounted power management module 900a is arranged adjacent to the cooling pipeline 900c and the power line 900d, but also the mounting supports of the vehicle-mounted power management module 900a, the cooling pipeline 900c, and the power line 900d can be integrated into the first mounting member 600, which reduces the development cost and the vehicle production cost. Of course, in other embodiments, the mounting supports of the cooling pipeline 900c, the power line 900d, and the vehicle-mounted power management module 900a can be separately provided.

[0057] In an embodiment, please refer to Figures 1 to 7, the floor body 100 is provided with a plurality of third reinforcing ribs, and the plurality of third reinforcing ribs include at least one of a fishbone reinforcing rib 120 and an H-shaped reinforcing rib. In this way, the third reinforcing ribs can improve the structural strength of the floor body 100, thereby guaranteeing the support force of the floor body 100 on the vehicle-mounted power management module 900a and the storage battery 900b, that is, effectively improving the local modal of the floor body 100, reducing the mode shape amplitude, and improving the in-vehicle noise. Of course, in other embodiments, the third reinforcing cross beam 500 also includes at least one of a Z-shaped reinforcing rib and other shapes of reinforcing ribs.

[0058] The application also provides a vehicle, which comprises a vehicle-mounted power management module 900a, a storage battery 900b, and a vehicle floor. The vehicle-mounted power management module 900a and the storage battery 900b are respectively mounted on the first mounting member 600 and the second mounting member 700. The specific structure of the vehicle floor is described above. Since the vehicle adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0059] The above is only an optional embodiment of the application, and does not limit the patent scope of the application.
