DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] See also Figures 1 to 8 The embodiment of the present application provides a rear floor structure for installing a driving module and a vehicle thereof, which can solve the problem in the related art that the intelligent driving module is laid flat on the rear floor, but no installation space is set on the rear floor, resulting in insufficient space on the rear floor of the vehicle.

[0028] At present, the intelligent driving module formed by integrating various driving modules on the car into the circuit board is laid flat on the rear floor, but there is no installation space on the rear floor, which will lead to insufficient space on the rear floor of the vehicle and fail to meet the safety requirements of the vehicle.

[0029] The intelligent driving module is laid flat on the rear floor, but there is no installation space on the rear floor, which will lead to the problem of insufficient space on the rear floor of the vehicle. On the first aspect, the embodiment of the present application provides a rear floor structure for installing a driving module, which includes: a rear floor body 1 and a protective cover structure 2, the rear floor body 1 is arranged under the vehicle base, the rear floor body 1 includes a first plate body 10 and a second plate body 12 connected to the first plate body 10, there is a height difference between the first plate body 10 and the second plate body 12, so that the top of the first plate body 10 is lower than the top of the second plate body 12, the first plate body 10 is formed with a mounting platform for installing the driving module, and the second plate body 12 is formed with a mounting platform for installing the on-board charger; the protective cover structure 2 is fixed on the first plate body 10, a driving module installation area 7 is formed between the protective cover structure 2 and the first plate body 10, and the protective cover structure 2 is used to protect the driving module installed on the first plate body 10.

[0030] In the present application, by lowering the height of the first plate body 10, a space is provided on the rear floor body 1 to accommodate the driving module, the protective cover structure 2 is fixed on the first plate body 10, and a driving module installation area 7 is formed between the protective cover structure 2 and the first plate body 10, so that the protective cover structure 2 cooperates with the first plate body 10 to protect the driving module.

[0031] Among them, the rear floor body 1 is installed under the vehicle seat. In the rear floor body 1, the original anti-diving convex structure of the seat is flattened to make a flat structure, and the height is appropriately lowered to reserve space for the installation of the intelligent driving module. That is to say, in this embodiment, the first plate body 10 and the second plate body 12 are set, and the height of the first plate body 10 is lowered to form a height difference between the top of the first plate body 10 and the top of the second plate body 12, and the horizontal plane where the top of the second plate body 12 is located is located above the horizontal plane where the top of the first plate body 10 is located. And the tops of the first plate body 10 and the second plate body 12 are set as planes, so the driving module can be installed on the top of the first plate body 10, and the on-board charger can be installed on the top of the second plate body 12, and no additional space in the vehicle is occupied.

[0032] Furthermore, a transition plate 11 is provided between the first plate 10 and the second plate 12, and the transition plate 11 is used to install a vehicle seat. The transition plate 11 is set to an inclined state, one end of the transition plate 11 is connected to the first plate 10, and the other end is connected to the second plate 12, and a rounded transition is provided at the connection between the first plate 10 and the transition plate 11, and a rounded transition is provided at the connection between the second plate 12 and the transition plate 11. By providing a rounded transition, the connection between the plates can be smoother and more fluent, avoiding the abruptness and inharmoniousness caused by the right-angle connection; at the same time, the rounded transition can disperse the stress concentration at the connection between the first plate 10, the second plate 12 and the transition plate 11, reduce the material fracture or deformation caused by the stress concentration, and the rounded transition can improve the strength and stability of the rear floor body 1.

[0033] Further, on this basis, see Figure 7 As shown, a reinforcement piece is further provided between the first plate body 10 and the transition plate body 11, one end of the reinforcement piece is connected to the transition plate body 11, and the other end is connected to the first plate body 10. In addition, reinforcing ribs are provided on the second plate body 12 along the length direction of the vehicle, and the structural strength of the rear floor body 1 is further strengthened by the provided reinforcement piece and the reinforcing ribs.

[0034] On the basis of the above-mentioned embodiment, in this embodiment, the protective cover structure 2 is fixed to the rear floor body 1 by screwing. It should be noted that after the protective cover structure 2 is installed on the rear floor body 1, the horizontal plane where the top of the protective cover structure 2 is located coincides or roughly coincides with the horizontal plane where the second plate body 12 is located. The coincidence here means that the horizontal plane where the top of the protective cover structure 2 is located is the same as the horizontal plane where the second plate body 12 is located, and the roughly coincidence means that there is a gap between the horizontal plane where the top of the protective cover structure 2 is located and the horizontal plane where the second plate body 12 is located. The size of the gap is determined according to the actual situation. It needs to be ensured that the protective cover structure 2 does not occupy additional space in the vehicle after being installed on the rear floor body 1.

[0035] In some possible embodiments, the protective cover structure 2 is set as an integrated plate structure, and the protective cover structure 2 includes a top plate and side plates, and the side plates are fixed on both sides of the top plate, and are screwed and fixed to the first plate body 10 of the rear floor body 1 through the side plates.

[0036] In some other possible embodiments, see Figure 1 As shown, the protective cover structure 2 includes a left protective cover 20 and a right protective cover 21. The left protective cover 20 is fixed to one side of the top of the first plate body 10; the right protective cover 21 is fixed to the other side of the top of the first plate body 10 and forms a central channel between the left protective cover 20 and the right protective cover 21.

[0037] In this embodiment, the left protective cover 20 and the right protective cover 21 are arranged to have the same structural shape. In addition, the structural shapes of the left protective cover 20 and the right protective cover 21 may also be different and can be set according to specific needs.

[0038] In the present application, the left protective cover 20 and the right protective cover 21 are provided with the same structural shape, so the left protective cover 20 is taken as an example for description below:

[0039] The left protective cover 20 includes a top plate and a side plate. The top plate is fixedly connected to the top end of the side plate. The top plate and the side plate are integrally formed. The side plate is fixed to the first plate body 10 by screwing.

[0040] In this embodiment, the top plate is arranged to be wavy, and in the top plate, the height of the top end close to the first plate body 10 is higher than the height close to the second plate body 12, so that the height of the top plate gradually decreases along the length direction of the car.

[0041] In this embodiment, the left protective cover 20 and the right protective cover 21 are separately arranged on both sides of the top of the first plate body 10, and a central channel is formed between the left protective cover 20 and the right protective cover 21. When the driving module is installed, it is installed between the bottom ends of the left protective cover 20 and the right protective cover 21.

[0042] The above embodiments are merely multiple possible implementations of the embodiments of the present application, and the embodiments of the present application are not limited thereto.

[0043] Therefore, the driving module is arranged in the driving module installation area 7 formed by the rear floor body 1 and the left protective cover 20 structure 2. This structure makes full use of the space of the rear floor body 1. In the general traditional structure, this is the anti-diving structure of the rear floor structure, and the space below the anti-diving structure is generally wasted and not utilized. The structure of the present application is to design the first plate body 10 in the rear floor body 1 into a plane shape, and weld the driving module mounting bracket 4 of the driving module on this plane, that is, the driving module mounting bracket 4 is fixedly connected to the top of the mounting platform of the first plate body 10, and the driving module mounting bracket 4 is used to fix driving modules of various specifications. In order to ensure that the driving module can be installed smoothly, the driving module mounting bracket 4 should be fixed on the first plate body 10 first, and then the driving module should be assembled on the driving module mounting bracket 4, and then the protective cover structure 2 is assembled. The main functions of the protective cover structure 2 are as follows: (1) protect the driving module and prevent the driving module from being squeezed by external force; (2) support the seat cushion and provide a fixing point for the seat cushion; (3) have the function of preventing the seat from diving, and its raised structure can effectively prevent the seat from diving during a collision.

[0044] On the basis of the above embodiment, in this embodiment, in order to solve the problem of insufficient mode of the rear floor body 1, the protective cover structure 2 is optimized as follows:

[0045] For further information, see Figure 3 As shown, a reinforcing rib 24 is provided at the top of the protective cover structure 2, and the reinforcing rib 24 is provided to penetrate both sides of the top of the protective cover structure 2 along the length direction of the automobile.

[0046] In addition to setting up the reinforcing ribs 24 to strengthen the shield structure 2, the cross-section of the reinforcing ribs 24 is also wavy. The wavy reinforcing ribs 24 can disperse and withstand external forces more effectively, thereby improving the strength of the overall structure of the shield structure 2. This design enables the shield structure 2 to distribute these forces more evenly when subjected to pressure, tension or shear force, reducing stress concentration and thus avoiding damage to the structure due to local overload; in addition, the wavy design can increase the stability of the shield structure 2 and reduce the vibration and deformation of the structure; at the same time, the wavy reinforcing ribs 24 have a stronger sense of hierarchy and dynamism visually, which can increase the aesthetics of the shield structure 2.

[0047] Further, the depth of the reinforcing rib 24 is set to be greater than or equal to a set value. In the present embodiment, the set value is set to 10 mm, that is, the depth of the reinforcing rib 24 is set to be greater than or equal to 10 mm. Generally, the depth of the reinforcing rib 24 is about 5 mm. The deeper the depth of the reinforcing rib 24, the better its modal state. Since deeper reinforcing ribs 24 mean that more materials are used, the overall stiffness of the shield structure 2 is increased. Stiffness is the ability of a structure to resist deformation. Higher stiffness means that the shield structure 2 is less likely to deform when subjected to force. Deeper reinforcing ribs 24 can more effectively disperse and withstand external forces, reduce stress concentration, and improve the vibration resistance of the structure, reducing deformation and damage risks under vibration loads, which helps to improve the overall stability and durability of the shield structure 2. Therefore, without affecting the layout of the driving module, the rib depth of the shield structure 2 is designed to be greater than or equal to 10 mm, which is twice the common depth, and can significantly improve its modal state. In addition, the structure of the reinforcing rib 24 is a front-to-back through-type, which is also very beneficial to the improvement of the modal state.

[0048] On the basis of the above-mentioned embodiment, in this embodiment, supporting legs 23 are arranged around the protective cover structure 2 , and the protective cover structure 2 is connected to the first plate body 10 through the supporting legs 23 .

[0049] In this embodiment, a support leg 23 is fixedly connected to the protective cover structure 2, and a screw connection point 22 is provided on the first plate body 10. The protective cover structure 2 is fixed by screwing the support leg 23 to the first plate body 10.

[0050] Generally, the number and position of the support legs 23 are determined according to actual conditions. Figure 3 As shown, Figure 3 The protective cover structure 2 shown in the figure comprises a left protective cover 20 and a right protective cover 21. A support leg 23 is fixed to one side of the left protective cover 20, and a support leg 23 is also fixed to the other side. The number of support legs 23 on the right protective cover 21 and the left protective cover 20 is the same.

[0051] In addition to the screw connection point 22 provided at the mounting position of the support leg 23, see Figure 3 As shown, screw connection points 22 are also provided on both sides of the first plate body 10 along the length direction of the vehicle, so that the protective cover structure 2 can be directly screwed to the first plate body 10 to improve the stability of the connection between the protective cover structure 2 and the first plate body 10.

[0052] On the basis of the above embodiment, in this embodiment, the rear floor structure further includes a crossbeam structure 3 , which is disposed on the rear floor body 1 and connected to the protective cover structure 2 .

[0053] It should be noted that, in addition to being connected to the first plate body 10 , the protective cover structure 2 is also connected and fixed to the beam structure 3 .

[0054] Among them, the crossbeam structure 3 includes: a front crossbeam 30 and a middle crossbeam 31, the front crossbeam 30 is arranged on the first plate body 10 and is connected to the protective cover structure 2; the middle crossbeam 31 is arranged on the first plate body 10 and is connected to the protective cover structure 2; wherein the protective cover structure 2 is arranged between the front crossbeam 30 and the middle crossbeam 31, and the protective cover structure 2, the front crossbeam 30 and the middle crossbeam 31 form a skeleton structure.

[0055] See also Figure 8 As shown, the middle cross beam 31 is disposed at the bottom end of the first plate body 10 and is connected and fixed to the first plate body 10 by screwing, and the front cross beam 30 is disposed at the end of the first plate body 10 and is also connected and fixed to the first plate body 10 by screwing. It should be noted that the connection method of the middle cross beam 31, the front cross beam 30 and the first plate body 10 is not limited to screwing, and can also be connected by welding, by gluing, etc.

[0056] Therefore, one end of the protective cover structure 2 is also connected to the front cross beam 30, and the other end is also connected to the middle cross beam 31. The front cross beam 30, the middle cross beam 31 and the protective cover structure 2 also form a skeleton structure. Figure 6 As shown, when the protective cover structure 2 includes a left protective cover 20 and a right protective cover 21, the left protective cover 20, the right protective cover 21, the front cross beam 30, and the middle cross beam 31 form an H-shaped skeleton structure. This structure enables the rear floor body 1 to have higher modal performance, thereby effectively ensuring the modal requirements of the driving module.

[0057] See also Figure 4 As shown, the driving module is arranged on the rear floor body 1 and below the left protective cover 20 and the right protective cover 21, without occupying the original space under the floor. By setting the front cross beam 30 and the rear cross beam, the space under the rear floor body 1 can form a fuel tank arrangement area 6, and the fuel tank of the extended-range or hybrid vehicle model can still be arranged, so that the structure has stronger compatibility.

[0058] On the basis of the above embodiment, in this embodiment, in order to further improve the structural strength of the rear floor body 1 , a reinforcing plate 5 is fixedly connected to the surface of the cross beam structure 3 . Specifically, the reinforcing plate 5 is fixed to the front cross beam 30 .

[0059] In this embodiment, since the reinforcing plate 5 and the front crossbeam 30 are connected to the left protective cover 20 and the right protective cover 21, and the left protective cover 20 and the right protective cover 21 are connected to the middle crossbeam 31, the left protective cover 20 and the right protective cover 21 have deep rib force-conducting structures, namely reinforcing ribs 24. When the reinforcing plate 5 and the front crossbeam 30 collapse under the collision force, the protective cover and the right protective cover 21 will be pulled, so that part of the force is transmitted to the middle crossbeam 31 through the left protective cover 20 and the right protective cover 21. Therefore, in this application, see Figure 5 As shown, compared with the traditional rear floor structure, in addition to the force transmission path A during a side collision, there are also force transmission paths B and C.

[0060] In summary, the rear floor body 1 in this application is flattened by smoothing the original raised structure of the seat anti-diving, and made into a flat structure, and the height is appropriately lowered to reserve space for the installation of the intelligent driving module. The left protective cover 20 in the protective cover structure 2 can be fixed on the rear floor body 1, the middle crossbeam 31 and the front crossbeam 30 of the rear floor by screwing; the right protective cover 21 can be fixed on the rear floor body 1, the middle crossbeam 31 and the front crossbeam 30 by screwing; the front crossbeam 30 and the rear floor body 1 can be welded together, and screwed together with the left protective cover 20 and the right protective cover 21; the middle crossbeam 31 and the rear floor body 1 can be welded together, and screwed together with the left protective cover 20 and the right protective cover 21; the driving module mounting bracket 4 is welded to the first plate body 10 on the rear floor body 1; the reinforcing plate 5 is welded to the front crossbeam 30; in this application, the rear floor structure can be diversified to meet the installation of different intelligent driving modules.

[0061] Compared with the conventional arrangement, the rear floor structure for installing the driving module provided in the present application utilizes the space wasted by the original anti-diving structure and does not occupy additional space in the vehicle; this structure meets the modal performance requirements of the driving module and the collision safety requirements of the whole vehicle. The skeleton of the new structure is H-shaped and has high strength. At the same time, the modality of the rear floor structure is also improved, that is, it meets the safety requirements of seat anti-diving and the modal requirements of the floor of the intelligent driving module; this structure has strong compatibility. This structure can be used not only in pure electric vehicles, but also in extended-range or hybrid vehicles. The space under the floor can still be used to arrange the fuel tank and its pipelines, etc.
