DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] See also Figures 1 to 5 The embodiments of the present application provide a vehicle door sill structure and a vehicle, which can solve the problem of excessive deformation of the battery pack due to squeezing during a side collision in the related art.

[0021] The threshold structure of new energy vehicles is an important safety and functional component at the bottom of the vehicle body. It not only supports the body and protects the battery, but also needs to take into account the requirements of lightweight, collision safety, sealing and waterproofing.

[0022] The existing threshold beam is easily deformed by collision in the area where the battery pack is installed with nuts, and cannot effectively ensure the rigidity of the battery pack installation point and protect the battery pack from deformation.

[0023] In response to the problem in the related art that the battery pack is squeezed and excessively deformed during a side collision, on the first hand, an embodiment of the present application provides a vehicle threshold structure, which includes: a threshold body, a threshold structure reinforcement 5 and a battery pack mounting beam 7, wherein the threshold body is provided with a accommodating cavity; the threshold structure reinforcement 5 is arranged inside the accommodating cavity, and a buffer energy-absorbing member is filled between the threshold and the inner wall of the accommodating cavity; a battery pack mounting space is provided on the battery pack mounting beam 7, and the battery pack mounting space is located on one side of the threshold structure reinforcement 5, and the battery pack mounting beam 7 is connected to the threshold body through a first connecting member 8, and the first connecting member 8 passes through the accommodating cavity and is fixed to the threshold structure reinforcement 5.

[0024] In the present application, a sill structure reinforcement 5 is provided inside the sill body to strengthen the structural strength of the sill body, and the sill structure reinforcement 5 is provided on one side of the battery pack installation space, and the connection between the battery pack installation beam 7 and the sill structure reinforcement 5 is strengthened by the first connecting member 8, thereby strengthening the installation point of the battery pack installation beam 7 and the entire X-direction battery pack area. In addition, a buffer energy-absorbing member is filled between the sill structure reinforcement 5 and the inner wall of the accommodating cavity. In the event of a side collision of the vehicle, the buffer energy-absorbing member can absorb energy, further protecting the battery pack from being squeezed during the collision, and effectively preventing the battery pack from being squeezed, excessively deformed, and other problems during a side collision.

[0025] In this embodiment, the first connecting member 8 is a bolt, and the rocker structure reinforcement 5 includes a frame 52. The frame 52 is provided with a retaining nut 50 for connecting to the rocker body and a mounting nut 51 for connecting to the battery pack mounting beam 7. To ensure that the rocker structure reinforcement 5 meets the requirements of both lightweight and high strength, the frame 52 is made of a high-strength non-metallic material. This ensures that the rocker structure reinforcement 5 maintains lightweight while also improving structural rigidity and fatigue resistance.

[0026] In this embodiment, the frame 52 is preferably made of a composite material composed of plastic and glass fiber. The plastic serves as the matrix material, while the glass fiber is dispersed within the plastic matrix as a reinforcement, enhancing the overall strength and toughness of the rocker structure reinforcement 5. In this embodiment, the plastic and glass fiber used are typically PA6 and GF35, respectively. PA6 (nylon 6), a semi-crystalline thermoplastic, is lightweight and tough; GF35 is a composite material reinforced with 35% glass fiber, offering high strength and rigidity.

[0027] When the door sill structure reinforcement 5 is manufactured, the positioning nuts 50 and the installation nuts 51 set on the frame 52 are pre-embedded in advance and formed integrally with the frame 52 when it is formed. This design method not only simplifies the assembly process, but also improves the overall strength and structural stability of the door sill structure reinforcement 5, and avoids the risk of loosening or falling off caused by the split connection.

[0028] At the same time, the positioning nut 50 plays a role in positioning when installing with the door sill body; the mounting nut 51 plays a role in installing the battery pack mounting beam 7. In this embodiment, please refer to Figure 2 The setting method shown is: a positioning nut 50 and a mounting nut 51 are respectively provided on both sides of the skeleton 52, and a mounting nut 51 is provided in the middle of the skeleton 52; the positioning nut 50 and the mounting nut 51 can also be provided at other positions according to actual needs to ensure the stability of the connection between the threshold structure reinforcement 5 and the battery pack mounting beam 7 and the threshold body.

[0029] On the basis of the above embodiment, in order to improve the lightweight degree of the skeleton 52, hollow areas are provided at intervals along the length direction of the skeleton 52; it should be noted that when providing the hollow areas, it is necessary to consider both the strength requirements and the lightweight requirements of the skeleton 52. Furthermore, in order to avoid the reduction of the structural strength of the hollow areas, reinforcing ribs are provided in the hollow areas so that the hollow areas are formed as follows. Figure 2 、 Figure 3 The “M”-shaped reinforcement structure shown in the embodiment is arranged at the location where the mounting nut 51 is arranged.

[0030] Based on the above embodiment, in this embodiment, the buffering energy absorbing member is fixed to the surface of the frame 52. When the rocker structure reinforcement member 5 is installed inside the rocker body, the buffering energy absorbing member is arranged between the surface of the frame 52 and the inner wall of the accommodating cavity.

[0031] The energy-absorbing component absorbs and disperses impact energy. It can be made of rubber, foam, or epoxy foam 9. In this embodiment, the energy-absorbing component comprises epoxy foam 9. The advantage of epoxy foam 9 is that it combines high-strength bonding with energy absorption while also providing lightweight performance. During the heat-curing process, the epoxy foam 9 expands 2-3 times its original size, filling the cavity between the frame 52 and the inner wall of the housing. This improves the local structural strength of the door sill body and simplifies the assembly process.

[0032] Furthermore, the buffer energy-absorbing member is arranged between two adjacent hollow areas, and, under the premise of meeting performance requirements, the hollow area at the top of the skeleton 52 and the hollow area at the bottom of the skeleton 52 are staggered, and the "M"-shaped reinforcement structure is also staggered synchronously, which can achieve the purpose of reducing weight and reducing parts costs.

[0033] In this embodiment, the thickness of the epoxy foam 9 is set to a value range of 3~5mm; and the epoxy foam 9 and the skeleton 52 are set to be two-color injection molding, that is, the epoxy foam 9 and the skeleton 52 are injection molded twice in the same mold through the two-color injection molding process to form an integrated composite structure. During the production, the skeleton 52 is first injection molded as the base material, and then the liquid epoxy foam 9 is injected into the mold in the second injection molding stage. During the curing process, the epoxy foam 9 expands and fills the cavity between the skeleton 52 and the inner wall of the accommodating cavity, forming a high-strength bond with the skeleton 52 and the inner wall of the accommodating cavity.

[0034] Building on the above-mentioned embodiment, in this embodiment, the length of the frame 52 is less than a set threshold. Because the mounting point tolerance requirements for the battery pack mounting beam 7 are relatively high, typically requiring a position accuracy of ±0.6mm, this tolerance requirement must be met when embedding the mounting nuts 51 in the rocker structure reinforcement 5. To meet this tolerance, the length of the rocker structure reinforcement 5 must be less than a set threshold. In this embodiment, the threshold is set to 500mm, meaning the length of the rocker structure reinforcement 5 must be limited to 500mm. If the length exceeds this threshold, the tolerance of the embedded mounting nuts 51 in the rocker structure reinforcement 5 will not meet the required tolerance.

[0035] However, battery packs typically exceed 500mm in length, requiring two or more sill reinforcements 5 to meet installation requirements. Connecting two or more sill reinforcements 5 requires further consideration of the connection strength between them. Therefore, structural adhesive connection grooves 53 are provided at the ends of the frame 52. When multiple sill reinforcements 5 are provided, a gap is created between the structural adhesive connection grooves 53 on adjacent sill reinforcements 5. In this embodiment, epoxy foam 9 can also be used as the structural adhesive. The spacing between the two sill reinforcements 5 is designed to be 5mm. Epoxy foam 9 is pre-placed in the structural adhesive connection grooves 53. The depth of the structural adhesive connection grooves 53 is designed to be between 6 and 8mm, and the thickness of the epoxy foam 9 is designed to be between 3 and 5mm. This ensures that after baking and foaming, the epoxy foam 9 connects the two or more sill reinforcements into a single unit, protecting the entire battery pack.

[0036] On the basis of the above embodiment, in this embodiment, the door sill body includes: a door sill beam 4 and a side panel assembly. The door sill beam 4 has an accommodating cavity therein; and the side panel assembly is connected to the door sill beam 4 .

[0037] In this embodiment, the threshold structure reinforcement 5 is arranged in the accommodating cavity inside the threshold beam 4. The dimensions of the threshold structure reinforcement 5 are smaller than the dimensions of the accommodating cavity. In this embodiment, the dimensions of the threshold structure reinforcement 5 are 3 mm smaller than the dimensions of the accommodating cavity to facilitate the foaming and filling of the epoxy foam 9.

[0038] The rocker reinforcement 5 is secured to the rocker beam 4 via a retaining nut 50. After the rocker body and rocker reinforcement 5 are painted and baked, the epoxy foam 9 on the rocker reinforcement 5 foams and fills the cavity, further strengthening the mounting point of the battery pack mounting beam 7 and the entire X-axis area where the battery pack resides. This solidified cavity protects the battery pack from compression during a side impact. CAE analysis also shows that the presence of this rocker reinforcement 5 reduces the amount of battery pack intrusion during a side impact by 12%, further improving crash performance and meeting performance targets.

[0039] On the basis of the above embodiment, in this embodiment, the side panel assembly includes: a side panel outer panel 1, a side panel inner panel patch 6 and a side panel reinforcement panel assembly.

[0040] Among them, the side panel outer panel 1 is connected to one side of the top end of the sill beam 4, and the bottom end of the side panel outer panel 1 extends toward the bottom end of the sill beam 4 so that the side panel outer panel 1 wraps one side of the sill beam 4 to improve the structural strength of the side of the sill body, and the side panel outer panel 1 and the sill beam 4 are fitted together and need to be coated with structural glue to be fixed to the sill beam 4, thereby enhancing the connection strength between the side panel outer panel 1 and the sill beam 4; the side panel inner panel patch 6 is connected to the other side of the top end of the sill beam 4, and the side panel inner panel patch 6 is provided to be connected to the side panel outer panel 1, at the same time, the side panel reinforcement panel assembly is arranged between the side panel outer panel 1 and the side panel inner panel patch 6 to improve the connection strength of the side panel assembly, and the bottom end of the side panel reinforcement panel assembly extends toward the bottom end of the sill beam 4, so that the side panel reinforcement panel assembly and the sill beam 4 are fitted together and need to be coated with structural glue to be fixed to the sill beam 4, thereby further improving the structural strength of the side of the sill body.

[0041] Furthermore, the side panel reinforcement assembly includes: a side panel inner panel body 3 and a side panel reinforcement body 2, the side panel inner panel body 3 is connected to the side panel inner panel patch 6; the side panel reinforcement body 2 is connected between the side panel inner panel body 3 and the side panel outer panel 1. The side reinforcement plate and the side inner panel body 3 are first spot-welded together to form a side reinforcement plate assembly, and a nut 51 is embedded in the rocker structure reinforcement 5. The rocker structure reinforcement 5 is first connected to the rocker beam 4 by riveting, and the side inner panel patch 6 is connected to the rocker beam 4 through a second connecting piece 10. The side reinforcement plate assembly and the side outer panel 1 are also connected to the rocker beam 4 through a second connecting piece 10. The contact surfaces of the side inner panel patch 6, the side reinforcement plate assembly and the side outer panel 1 with the rocker beam 4 need to be coated with structural adhesive. After being welded together to form a white body, the white body is painted and baked, and the epoxy adhesive of the rocker structure reinforcement 5 is foamed and cured, filling the accommodating cavity of the rocker beam 4. After the battery pack mounting beam 7 is connected to the white body by bolts, it further protects the battery pack from being squeezed during a collision.

[0042] It should also be noted that, in this embodiment, the second connecting member 10 is configured as a screw, and the side panel inner panel patch 6, the side panel reinforcement panel assembly and the side panel outer panel 1 are connected to the rocker beam 4 through FDS (Flow Drill Screw).

[0043] In summary, the present application provides a battery pack installation structure through a novel structural design. At the same time, the structure has better performance and is safer, provides better protection for the battery pack, and enhances the competitiveness of the entire vehicle. The installation nut 51 is directly embedded in the door sill structure reinforcement 5, and the skeleton 52 characteristics of the door sill structure reinforcement 5 and the epoxy foam 9 are arranged at intervals to reduce weight and reduce costs. At the same time, the epoxy foam 9 is designed on the side of the door sill structure reinforcement 5 to achieve the connection of multiple door sill structure reinforcements 5.
