Description

Technical Field

[0001] This application relates to the automotive field, and more particularly to a rear floor structure for mounting a driving module and an automotive thereof. Background Technology

[0002] Currently, the intelligent driving modules formed by integrating various controllers in automobiles into circuit boards are laid flat on the rear floor. However, there is no installation space on the rear floor, which leads to insufficient space on the rear floor of the vehicle and fails to meet the vehicle's safety requirements. Summary of the Invention

[0003] This application provides a rear floor structure for installing a driving module and a vehicle thereof, which can solve the problem in the related art where the intelligent driving module is laid flat on the rear floor, but no installation space is provided on the rear floor, resulting in insufficient space on the rear floor of the vehicle.

[0004] In a first aspect, embodiments of this application provide a rear floor structure for installing a driving module, comprising: a rear floor body and a protective cover structure. The rear floor body is disposed below the vehicle base. The rear floor body includes a first plate and a second plate connected to the first plate. There is a height difference between the first plate and the second plate, such that the top of the first plate is lower than the top of the second plate. An installation platform for installing the driving module is formed on the first plate, and an installation platform for installing an on-board charger is formed on the second plate. The protective cover structure is fixed to the first plate, and a driving module installation area is formed between the protective cover structure and the first plate. The protective cover structure is used to protect the driving module installed on the first plate. In this application, by lowering the height of the first plate, space is provided on the rear floor body to accommodate the driving module. The protective cover structure is fixed to the first plate, and a driving module installation area is formed between the protective cover structure and the first plate, so that the protective cover structure cooperates with the first plate to protect the driving module.

[0005] In conjunction with the first aspect, in one embodiment, the rear floor structure further includes a beam structure disposed on the rear floor body and connected to the protective cover structure.

[0006] In conjunction with the first aspect, in one embodiment, the crossbeam structure includes a front crossbeam and a middle crossbeam. The front crossbeam is disposed on the first plate and connected to the protective cover structure; the middle crossbeam is disposed on the first plate and connected to the protective cover structure; wherein the protective cover structure is disposed between the front crossbeam and the middle crossbeam, and the protective cover structure, the front crossbeam, and the middle crossbeam form a skeleton structure. The left protective cover, the right protective cover, the front crossbeam, and the middle crossbeam form an H-shaped skeleton structure. This structure enables the rear floor body to possess high modal performance, thereby effectively ensuring the modal requirements of the driving module.

[0007] In conjunction with the first aspect, in one embodiment, a reinforcing plate is fixedly connected to the surface of the beam structure.

[0008] In conjunction with the first aspect, in one embodiment, the protective cover structure includes: a left protective cover and a right protective cover, the left protective cover being fixed to one side of the top of the first plate; the right protective cover being fixed to the other side of the top of the first plate, and forming a central channel between the right and left protective covers.

[0009] In conjunction with the first aspect, in one embodiment, the protective cover structure has a reinforcing rib at its top, which extends along both sides of the top of the protective cover structure along the length of the vehicle; the protective cover structure has supporting legs around its perimeter, and the protective cover structure is connected to the first plate through the supporting legs. The left and right protective covers have deep-rib force-guiding structures, i.e., reinforcing ribs. When the reinforcing plate and the front crossbeam are subjected to impact force and collapse, they will pull the protective covers and the right protective cover, thus transferring a portion of the force to the middle crossbeam through the protective covers and the right protective cover.

[0010] In conjunction with the first aspect, in one embodiment, the cross-section of the reinforcing rib is wavy, and the depth of the reinforcing rib is greater than or equal to a set value.

[0011] In conjunction with the first aspect, in one embodiment, the set value is 10mm. Designing the rib depth of the protective cover structure to be greater than or equal to 10mm, which is twice the common depth, can significantly improve its modality. In addition, the structure of the reinforcing rib is a through-type structure, which is also very beneficial to modal improvement.

[0012] In conjunction with the first aspect, in one embodiment, a transition plate is provided between the first plate and the second plate. The transition plate is used to install a vehicle seat. One end of the transition plate is connected to the first plate, and the other end is connected to the second plate. The connection between the first plate and the transition plate is rounded, and the connection between the second plate and the transition plate is also rounded. By providing rounded transitions, the connection between the plates can be smoother and more fluid, avoiding the abruptness and disharmony caused by right-angle connections. At the same time, rounded transitions can disperse stress concentration at the plate connection, reducing material fracture or deformation caused by stress concentration. Rounded transitions can improve the strength and stability of the rear floor body. A driving module mounting bracket is fixedly connected to the top of the mounting platform of the first plate.

[0013] Secondly, embodiments of this application provide a vehicle comprising: a rear floor structure as described above.

[0014] The beneficial effects of the technical solutions provided in this application include:

[0015] This application provides a rear floor structure for installing a driving module and a vehicle thereof. By reducing the height of the first plate, the rear floor body has space to accommodate the driving module. A protective cover structure is fixed to the first plate, and a driving module installation area is formed between the protective cover structure and the first plate, so that the protective cover structure cooperates with the first plate to protect the driving module.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

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

[0028] Currently, the various driving modules in a car are integrated into a circuit board to form an intelligent driving module that is laid flat on the rear floor. However, there is no installation space on the rear floor, which leads to insufficient space on the rear floor of the vehicle and fails to meet the vehicle's safety requirements.

[0029] To address the issue of insufficient rear floor space in vehicles where the intelligent driving module is laid flat on the rear floor but no installation space is provided, this application provides a rear floor structure for installing a driving module. The structure includes a rear floor body 1 and a protective cover structure 2. The rear floor body 1 is located below the vehicle base and includes a first plate 10 and a second plate 12 connected to the first plate 10. There is a height difference between the first plate 10 and the second plate 12, such that the top of the first plate 10 is lower than the top of the second plate 12. The first plate 10 has an installation platform for installing the driving module, and the second plate 12 has an installation platform for installing an on-board charger. The protective cover structure 2 is fixed to the first plate 10, forming a driving module installation area 7 between the protective cover structure 2 and the first plate 10. The protective cover structure 2 protects the driving module installed on the first plate 10.

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

[0031] The rear floor body 1 is installed under the vehicle seat. The original anti-submarining protrusion of the seat in the rear floor body 1 is flattened, creating a flat structure with a lowered height to provide space for the installation of the intelligent driving module. In other words, in this embodiment, a first plate 10 and a second plate 12 are provided. The height of the first plate 10 is lowered, creating a height difference between the top of the first plate 10 and the top of the second plate 12, with the horizontal plane of the top of the second plate 12 above the horizontal plane of the top of the first plate 10. The tops of both the first plate 10 and the second plate 12 are made flat, allowing the driving module to be installed on the top of the first plate 10 and the onboard charger to be installed on the top of the second plate 12, without occupying additional interior space.

[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 the vehicle seat. The transition plate 11 is set in an inclined state, with one end connected to the first plate 10 and the other end connected to the second plate 12. The connection between the first plate 10 and the transition plate 11 is rounded, and the connection between the second plate 12 and the transition plate 11 is also rounded. By setting rounded transitions, the connection between the plates can be smoother and more fluid, avoiding the abruptness and disharmony caused by right-angle connections. At the same time, rounded transitions can disperse stress concentration at the connection between the first plate 10, the second plate 12, and the transition plate 11, reducing material fracture or deformation caused by stress concentration. Rounded transitions can improve the strength and stability of the rear floor body 1.

[0033] Furthermore, based on this, see Figure 7 As shown, a reinforcing member is also provided between the first plate 10 and the transition plate 11. One end of the reinforcing member is connected to the transition plate 11, and the other end is connected to the first plate 10. In addition, a reinforcing rib is provided on the second plate 12 along the length of the vehicle. The structural strength of the rear floor body 1 is further enhanced by the provided reinforcing member and the reinforcing rib.

[0034] Based on the above embodiments, in this embodiment, the protective cover structure 2 is fixed to the rear floor body 1 by screws. It should be noted that after the protective cover structure 2 is installed on the rear floor body 1, the horizontal plane of the top of the protective cover structure 2 coincides with or approximately coincides with the horizontal plane of the second plate 12. Here, coincidence means that the horizontal plane of the top of the protective cover structure 2 and the horizontal plane of the second plate 12 are the same horizontal plane; approximately coincidence means that there is a gap between the horizontal plane of the top of the protective cover structure 2 and the horizontal plane of the second plate 12. The size of the gap is determined according to the actual situation, and it is necessary to ensure that the protective cover structure 2 does not occupy additional interior space after being installed on the rear floor body 1.

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

[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 10; the right protective cover 21 is fixed to the other side of the top of the first plate 10, and forms a central channel with the left protective cover 20.

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

[0038] In this application, the left protective shield 20 and the right protective shield 21 have the same structural shape, therefore the following description will take the left protective shield 20 as an example:

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

[0040] In this embodiment, the top plate is set to a wave shape, and in the top plate, the height of the side of its top end near the first plate 10 is higher than the height of the side near the second plate 12, so that the height of the top plate gradually decreases along the length of the vehicle.

[0041] In this embodiment, the left protective cover 20 and the right protective cover 21 are separately disposed on both sides of the top of the first plate 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 various possible implementations of the embodiments of this application, and the embodiments of this 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 general conventional structures, this is the anti-submersion structure of the rear floor structure, and the space below the anti-submersion structure is generally wasted and not utilized. The structure of this application is to design the first plate 10 in the rear floor body 1 as a planar 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 10. The driving module mounting bracket 4 is used to fix various specifications of driving modules. 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 10 first, then the driving module should be assembled on the driving module mounting bracket 4, and then the protective cover structure 2 should be 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 forces; (2) Support the seat cushion and provide a fixing point for the seat cushion; (3) Have the function of preventing seat submersion. Its raised structure can effectively prevent the seat from submerging during the collision.

[0044] Based on the above embodiments, in this embodiment, to solve the problem of insufficient modalities in the rear floor body 1, the following optimizations were made to the protective cover structure 2:

[0045] Further, see Figure 3 As shown, the top of the protective cover structure 2 is provided with a reinforcing rib 24, and the reinforcing rib 24 is arranged to penetrate through both sides of the top of the protective cover structure 2 along the length of the vehicle.

[0046] In addition to reinforcing the protective cover structure 2 with reinforcing ribs 24, the cross-section of the reinforcing ribs 24 is wavy. The wavy reinforcing ribs 24 can more effectively disperse and withstand external forces, thereby improving the overall structural strength of the protective cover structure 2. This design allows the protective cover structure 2 to distribute these forces more evenly when subjected to pressure, tension, or shear forces, reducing stress concentration and thus preventing structural damage due to localized overload. Furthermore, the wavy design increases the stability of the protective cover structure 2, reducing structural vibration and deformation. Simultaneously, the wavy reinforcing ribs 24 have a stronger sense of layering and dynamism, enhancing the aesthetics of the protective cover structure 2.

[0047] Furthermore, the depth of the reinforcing rib 24 is set to be greater than or equal to a predetermined value. In this embodiment, the predetermined value is set to 10mm, meaning the depth of the reinforcing rib 24 is set to be greater than or equal to 10mm. Generally, the depth of the reinforcing rib 24 is around 5mm. The deeper the reinforcing rib 24, the better its modal characteristics. Since deeper reinforcing ribs 24 mean more material is used, this increases the overall stiffness of the protective cover structure 2. Stiffness is the structure's ability to resist deformation. Higher stiffness means the protective cover structure 2 is less prone to deformation under stress. Deeper reinforcing ribs 24 can more effectively disperse and bear external forces, reducing stress concentration and improving the structure's vibration resistance, reducing the risk of deformation and damage under vibration loads. This helps improve the overall stability and durability of the protective cover structure 2. Therefore, without affecting the arrangement of the driving module, designing the rib depth of the protective cover structure 2 to be greater than or equal to 10mm, twice the common depth, can significantly improve its modal characteristics. Additionally, the front-to-back through-type structure of the reinforcing rib 24 is also very beneficial for modal improvement.

[0048] Based on the above embodiments, in this embodiment, the protective cover structure 2 is provided with supporting legs 23 around its perimeter, and the protective cover structure 2 is connected to the first plate 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 10. The protective cover structure 2 is fixed by screwing the support leg 23 to the first plate 10.

[0050] Generally, the number and position of the support legs 23 are determined based on the actual situation. For example, see... Figure 3 As shown, Figure 3 The protective shield structure 2 shown includes a left protective shield 20 and a right protective shield 21. A support leg 23 is fixed on one side of the left protective shield 20 and another support leg 23 is fixed on the other side. The right protective shield 21 has the same number of support legs 23 as the left protective shield 20.

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

[0052] Based on the above embodiments, 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 10, the protective cover structure 2 is also connected and fixed to the crossbeam structure 3.

[0054] The crossbeam structure 3 includes a front crossbeam 30 and a middle crossbeam 31. The front crossbeam 30 is disposed on the first plate 10 and connected to the protective cover structure 2. The middle crossbeam 31 is disposed on the first plate 10 and connected to the protective cover structure 2. The protective cover structure 2 is disposed 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 Figure 8 As shown, the middle crossbeam 31 is located at the bottom of the first plate 10 and is fixed to the first plate 10 by screwing. The front crossbeam 30 is located at the end of the first plate 10 and is also fixed to the first plate 10 by screwing. It should be noted that the connection method between the middle crossbeam 31, the front crossbeam 30 and the first plate 10 is not limited to screwing; it can also be connected by welding, adhesive bonding, etc.

[0056] Therefore, one end of the protective cover structure 2 is also connected to the front crossbeam 30, and the other end is also connected to the middle crossbeam 31. The front crossbeam 30, the middle crossbeam 31, and the protective cover structure 2 also form a skeleton structure. See also 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 crossbeam 30, and the middle crossbeam 31 form an H-shaped skeleton structure. This structure enables the rear floor body 1 to have high modal performance, thereby effectively ensuring the modal requirements of the driving module.

[0057] See 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 space under the original floor. Through the front crossbeam 30 and the rear crossbeam, the space under the rear floor body 1 can form the fuel tank arrangement area 6, which can still accommodate the fuel tank of range-extended or hybrid vehicles, thus making the structure highly compatible.

[0058] Based on the above embodiments, 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 crossbeam structure 3. Specifically, the reinforcing plate 5 is fixed to the front crossbeam 30.

[0059] In this embodiment, since the reinforcing plate 5, the front crossbeam 30 are connected to the left protective cover 20 and the right protective cover 21, and the left and right protective covers 20 and 21 are connected to the middle crossbeam 31, and the left and right protective covers 20 and 21 have deep rib force-guiding structures, namely reinforcing ribs 24, when the reinforcing plate 5 and the front crossbeam 30 are crushed by impact force, they will pull the protective covers and the right protective cover 21, so that a part of the force is transmitted to the middle crossbeam 31 through the left and right protective covers 20 and 21. Therefore, in this application, see Figure 5 As shown, compared to the traditional rear floor structure, which only has force transmission path A in the event of a side impact, it also has force transmission path B and force transmission path C.

[0060] In summary, the rear floor body 1 in this application flattens out the original seat anti-submersion protrusion structure, making it a flat structure with an appropriately reduced height, reserving space for the installation of the intelligent driving module. The left protective cover 20 in the protective cover structure 2 can be fixed to the rear floor body 1, the middle crossbeam 31, and the front crossbeam 30 of the rear floor by screws; the right protective cover 21 can be fixed to the rear floor body 1, the middle crossbeam 31, and the front crossbeam 30 by screws; the front crossbeam 30 can be welded to the rear floor body 1 and screwed to the left and right protective covers 20 and 21; the middle crossbeam 31 can be welded to the rear floor body 1 and screwed to the left and right protective covers 20 and 21; the driving module mounting bracket 4 is welded to the first plate 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 requirements of different intelligent driving modules.

[0061] Compared to conventional layouts, the rear floor structure for installing the driving module provided in this application utilizes the space wasted by the original anti-submersion structure without occupying additional interior space. This structure meets the modal performance requirements of the driving module and the overall vehicle collision safety requirements. The new structure has an H-shaped frame with high strength, while also improving the modal performance of the rear floor structure, satisfying both the seat anti-submersion safety requirements and the intelligent driving module's modal requirements for the floor. This structure has strong compatibility; it can be used not only in pure electric vehicles but also in range-extended or hybrid vehicles, and the space under the floor can still accommodate the fuel tank and its piping.

[0062] Secondly, embodiments of this application provide a vehicle comprising: the rear floor structure provided in any of the above embodiments of this application.

[0072] Based on the above embodiments, in this embodiment, a transition plate 11 is provided between the first plate 10 and the second plate 12; a driving module mounting bracket 4 is fixedly connected to the top of the first plate 10.

[0073] In this application, the rear floor body 1 has its original seat anti-submersion protrusion structure flattened to create a planar structure with a lowered height, reserving space for the installation of the intelligent driving module.
