Description

Technical Field

[0001] This application relates to the field of vehicle body structure technology, specifically a vehicle body sill structure and a vehicle. Background Technology

[0002] Currently, in the vehicle body, the sill is an important structure of the passenger compartment, mainly providing crash resistance and rigidity. For example, it bears the crash resistance requirements of the passenger compartment under collision conditions, and provides the rigidity requirements for installing components such as battery packs or body decorations. However, traditional sill structures often have problems with insufficient structural strength or stress concentration after a collision. Under collision conditions, the load is easily transferred to the surrounding area of ​​the passenger compartment, resulting in a reduction in the safety of the passenger compartment. Summary of the Invention

[0003] In view of this, it is necessary to provide a vehicle body sill structure that can improve safety and a vehicle having such a vehicle body sill structure.

[0004] This application provides a vehicle sill structure, including an inner sill plate, an outer sill plate, a filler, and a tube beam. The outer sill plate is connected to the inner sill plate, and a cavity exists between the outer sill plate and the inner sill plate. The filler is disposed in the cavity, and its opposite sides contact the inner sill plate and the outer sill plate, respectively. The filler fills the space between the inner sill plate and the outer sill plate. The filler has an installation channel that extends along the length of the filler. The tube beam passes through the installation channel, and its two ends are connected to the inner sill plate.

[0005] The aforementioned vehicle sill structure, by placing a filler in the cavity between the inner and outer sill panels and inserting a tubular beam through the filler, not only provides support and filling stiffness for the inner and outer sill panels but also forms a stress-dispersing transmission structure. In the event of a side collision, the load stress on the outer sill panel can be first transferred to the filler in contact with it. The filler can disperse the stress and transfer it to the tubular beam. Since the two ends of the tubular beam are fixed to the inner sill panel, the stress can be further dispersed to the vehicle floor and surrounding structure, avoiding local stress concentration. This enhances the stiffness and deformation resistance of the structure around the floor, thereby improving the safety of the passenger compartment.

[0006] In some embodiments, there are multiple fillers, which are spaced apart within the cavity.

[0009] In some embodiments, the inner sill plate and the outer sill plate are connected on one side of the filler, and there is a gap between the connection between the inner sill plate and the outer sill plate and the filler.

[0010] In some embodiments, at least one groove is provided on at least one side of the tube beam, the groove extending along the length of the tube beam, and the filler has a protrusion in the installation channel, the protrusion being disposed in the groove.

[0027] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, this application provides a vehicle sill structure 100 and a vehicle. The vehicle includes the vehicle sill structure 100, a crossbeam 200, and a floor 300. The vehicle sill structure 100 forms the sill of the vehicle's passenger compartment. The floor 300 serves as the floor of the vehicle's passenger compartment and is connected to the vehicle sill structure 100. Multiple crossbeams 200 are provided on the floor 300 as the frame to support the floor 300. In the vehicle, there is a vehicle sill structure 100 on each of the left and right sides of the vehicle. The sill extends along the longitudinal direction Y of the vehicle. The crossbeam 200 extends along the transverse direction X of the vehicle. Each end of the crossbeam 200 is connected to a vehicle sill structure 100. The floor 300 is also connected to a vehicle sill structure 100 on each side along the transverse direction X. Here, the longitudinal direction Y refers to the front-to-back direction when the vehicle is traveling, and the transverse direction X refers to the left-to-right direction when the vehicle is traveling.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the sill reinforcement structure 100 includes an inner sill plate 10, an outer sill plate 20, a tube beam 30, and a filler 40. The inner sill plate 10 connects to the end of the crossbeam 200, and the outer sill plate 20 is located on the side of the inner sill plate 10 away from the crossbeam 200 and the floor 300. The outer sill plate 20 is connected to the inner sill plate 10 to form a sill perpendicular to the crossbeam 200. A cavity 50 is provided between the inner sill plate 10 and the outer sill plate 20. The tube beam 30 and the filler 40 are both disposed within the cavity 50. Both ends of the tube beam 30 are fixed to the inner sill plate 10, so that the tube beam 30 is fixed relative to the sill. The filler 40 is provided with an installation channel 41, through which the tube beam 30 passes. A groove 31 is provided on the side of the tube beam 30, extending along the length of the tube beam 30 to increase the outer perimeter of the cross-section of the tube beam 30, thereby increasing the rigidity of the tube beam 30. The infill member 40 contacts the inner sill plate 10 and the outer sill plate 20 on opposite sides, respectively, so that the tube beam 30 is connected to the inner sill plate 10 and the outer sill plate 20 at the position of the infill member 40. The infill member 40 fills between the inner sill plate 10 and the outer sill plate 20, so that after being subjected to force, the infill member 40 disperses the force through multiple cells 43 to absorb energy, thereby reducing stress concentration in the sill. The end of the infill member 40 corresponds to the end of the crossbeam 200 along the transverse X direction to shorten the force transmission path between the infill member 40 and the crossbeam 200.

[0030] The tube beam 30 has increased stiffness through the groove 31, and the filler 40 and the end of the crossbeam 200 correspondingly shorten the stress transmission path, so that the crossbeam 200, filler 40 and tube beam 30 form a stress transmission path with greater stiffness and shorter path. Since load transmission tends to be carried out through a path with greater stiffness and shorter path, all the crossbeams 200, filler 40 and tube beam 30 around the floor 300 can form a closed stress transmission path (e.g., Figure 2 (As shown by the light gray double arrows) Under collision conditions, the closed stress transfer path can disperse and transfer the load through multiple paths, reducing local stress concentration, thereby enhancing the stiffness and deformation resistance of the structure surrounding the floor 300, and thus improving the safety of the occupant compartment.

[0031] In some embodiments, such as Figure 2 As shown, the floor 300 is provided with multiple parallel crossbeams 200. One crossbeam 200 is located at the front edge of the floor 300, for example, as a crossbeam for the front seat of a vehicle. Another crossbeam 200 is located at the rear edge of the floor 300, for example, as a crossbeam for the rear seat of a vehicle. The remaining crossbeams 200 are located between the front and rear edges of the floor 300. The left and right ends of the multiple crossbeams 200 are respectively connected to the inner sill plates 10 on the left and right sides of the vehicle. The front end of the tube beam 30 corresponds to the end of the frontmost crossbeam 200 along the transverse X, and the rear end of the tube beam 30 corresponds to the end of the rearmost crossbeam 200 along the transverse X. The end of each crossbeam 200 between the front and rear edges of the floor 300 corresponds to a filler 40 along the transverse X, thus forming a grid-shaped closed stress transmission path. When a collision occurs at a location around the floor 300, the collision load can be dispersed and transmitted through multiple paths, reducing local stress concentration and improving the safety of the passenger compartment.

[0032] In some embodiments, such as Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, the filler 40 includes an outer wall 42 and a plurality of arrayed cells 43. The outer wall 42 forms a receiving cavity 44, and the plurality of cells 43 are located within the receiving cavity 44. Each cell 43 is hollow, so that when the filler 40 is subjected to force, the force is dispersed through the plurality of cells 43 to absorb energy, thereby reducing stress concentration in the sill. In addition, each cell 43 has a cell axis P, and the cell wall of each cell 43 extends along the cell axis P, which is perpendicular to the length direction of the tube beam 30. For example, the cell wall of the cell 43 extends in the transverse direction X, so that the cell wall forms a vertical support relationship with the inner sill plate 10, the outer sill plate 20 and the tube beam 30. Since the force of the crossbeam 200 is transmitted in the transverse direction X, the vertical support relationship can provide higher strength and stiffness to the sill in the transverse direction X, making the load-bearing capacity of the filler 40 stronger, reducing the risk of breakage of the filler 40, and further improving the strength of the stress transmission path.

[0033] Optionally, each cell 43 is a hexagonal prism structure, and the array of cells 43 forms a honeycomb structure along the transverse X-shaped cross-section. The honeycomb structure has the advantages of the shortest perimeter and the largest area, that is, obtaining the maximum strength with the least amount of material and effectively distributing the stress. It is understood that in other embodiments, each cell 43 may also be a triangular prism, a square prism, or other regular or irregular pattern arrangement to meet different actual working conditions.

[0034] Optionally, the outer wall 42 and multiple cells 43 of the filler 40 are integrally molded by injection molding. The specific material can be a plastic composite reinforcement material, such as glass fiber reinforced polypropylene, to improve production efficiency and cost and reduce the weight of the filler 40.

[0035] In some embodiments, the outer wall 42 of the filler 40 has a plate-like structure to cover the cells 43 inside the receiving cavity 44, which can improve the overall structural strength of the filler 40 and prevent the cells 43 from collapsing or breaking during stress, thereby better performing the functions of energy absorption and force transmission. The outer wall 42 includes a top surface 421, a bottom surface 422, and a middle surface 423. The middle surface 423 connects the top surface 421 and the bottom surface 422. The middle surface 423 is the side of the filler 40 facing the sill outer plate 20. The middle surface 423 fits the inner surface of the sill outer plate 20. Since the bottom side of the sill outer plate 20 has a concave stepped surface 21 to adapt to the shape and installation requirements of the vehicle bottom sill area, the middle surface 423 has a corresponding recess 424, which can not only cooperate with the stepped surface 21 to make the filler 40 fit the inner surface of the sill outer plate 20. The full contact between the sill outer plate 20 and the filler 40 also results in the cross-sectional width of the portion above the recess 424 being greater than that below the recess 424. This variable cross-sectional structure, which is wider at the top and narrower at the bottom, gives the filler 40 a larger moment of inertia, improving its bending and compressive strength. In addition, the step surface 21 and the recess 424 increase the effective contact area between the filler 40 and the sill outer plate 20 in the transverse X direction, increasing the path of load stress from the sill outer plate 20 to the filler 40 and further dispersing the stress.

[0036] In some embodiments, such as Figure 4 and Figure 5 As shown, the filler 40 has extension arms 45 on opposite sides along the length of the tube beam 30. The side of the extension arm 45 facing the tube beam 30 has a first assembly part 451. The tube beam 30 has a second assembly part 32 corresponding to the first assembly part 451. The first assembly part 451 and the second assembly part 32 are assembled together to fix the filler 40 and the tube beam 30.

[0037] Optionally, the first assembly part 451 is a snap fastener, and the second assembly part 32 is a slot. The snap fastener is snapped into the slot to fix the filler 40 and the tube beam 30. The snap fastener can be pressed in once through elastic deformation to complete the fixation, reducing the number of operations and parts, and facilitating the quick installation of the filler 40.

[0038] Optionally, the first assembly part 451 is a through hole and the second assembly part 32 is a threaded hole. The through hole and the threaded hole are aligned and set. Bolts are passed through the through hole and the threaded hole in sequence and tightened to fix the filler 40 to the tube beam 30. The bolt connection can facilitate the disassembly and removal of the filler 40 for later maintenance.

[0039] Optionally, the first assembly part 451 is a positioning pin, and the second assembly part 32 is a positioning hole. The positioning pin is inserted into the positioning hole to achieve positioning. At the same time, adhesive is applied to the positioning hole or the contact surface between the extension arm 45 and the tube beam 30. After curing, an adhesive bond is formed, which can provide stronger connection strength.

[0040] In some embodiments, such as Figure 7 As shown, the inner sill plate 10 and the outer sill plate 20 are connected above and below the filler 40. A gap 60 is formed between the connection between the inner sill plate 10 and the outer sill plate 20 and the filler 40. Specifically, the gap 60 is formed at the bottom and top of the filler 40. The gap 60 allows the anti-rust paint to flow within the sill, enabling the paint to penetrate more fully and coat evenly on the inner surface of the inner sill plate 10, the inner surface of the outer sill plate 20, the outer wall of the pipe beam 30, the outer wall 42 of the filler 40, and all weld areas. This avoids problems such as missing paint film on the inner wall caused by the completely sealed cavity in traditional closed sills, thereby improving the corrosion resistance of the sill. Furthermore, the gap 60 provides deformation space, allowing the filler 40 to deform upon impact, further absorbing energy and reducing the peak force transmission. For example, the vertical width of the gap 60 is approximately 3 mm to ensure the flow of the anti-rust paint.

[0041] In some embodiments, such as Figure 4 and Figure 7 As shown, the tube beam 30 has at least one groove 31 on each of its opposite sides along the transverse X direction. The arrangement of multiple grooves 31 further increases the outer perimeter of the tube beam 30's cross-section, improving its bending and torsional resistance. Preferably, the tube beam 30 has one groove 31 on each of its opposite sides along the transverse X direction, making its cross-section "I"-shaped, i.e., the tube beam 30 is an I-beam. The I-beam can improve the stiffness of the tube beam 30, and the symmetrical I-beam can make the stress distribution more uniform, reducing local stress concentration, thereby improving the overall structural strength of the threshold. In other embodiments, the cross-section of the tube beam 30 can also be "U"-shaped, etc., to adapt to different design requirements.

[0042] In some embodiments, the tube beam 30 is a hollow beam to reduce its weight and cost. For example, the tube beam 30 is formed from high-strength steel using a hot-expansion process, and different wall thicknesses can be used to match the crash performance requirements of vehicles of different weights. Furthermore, the hollow tube beam 30 can absorb energy through deformation, reducing peak force transmission. In other embodiments, the tube beam 30 can also be a solid beam to provide higher strength and stiffness.

[0043] In some embodiments, such as Figure 7 As shown, the filler 40 has a protrusion 46 in the installation channel 41. The protrusion 46 is located in the groove 31. The cooperation between the protrusion 46 and the groove 31 can increase the contact area between the cell 43 in the filler 40 and the tube beam 30, thereby dispersing the force and reducing stress concentration. In addition, it can further restrict the movement of the filler 40 relative to the tube beam 30, improve the stability of the filler 40, and thus ensure the effective closed stress transmission path.

[0044] In some embodiments, such as Figure 2and Figure 3 As shown, the inner sill plate 10 includes a first inner plate segment 11, a second inner plate segment 12, a first connecting plate 13, and a second connecting plate 14. The front end of the first inner plate segment 11 connects to the vehicle's pillar 400, which is connected to the outer sill plate 20. Preferably, the pillar 400 is the vehicle's A-pillar, specifically the pillar between the vehicle's windshield and the left and right front doors. The rear end of the first inner plate segment 11 connects to the front end of the second inner plate segment 12, which connects to other vehicle frame components. The first connecting plate 13 is located on the side of the pillar 400 facing the outer sill plate 20, and the second connecting plate 14 is located on the side of the second inner plate segment 12 facing the outer sill plate 20. The first connecting plate 13 is used to fix the front end of the tube beam 30, and the second connecting plate 14 is used to fix the rear end of the tube beam 30.

[0045] Optionally, the first inner plate segment 11, the second inner plate segment 12, the first connecting plate 13, the second connecting plate 14, the outer sill plate 20, and the column 400 are all made of high-strength steel by stamping and roll forming, and assembled by welding and bolting. Since the first inner plate segment 11 and the second inner plate segment 12, which are stamped and roll formed, have a concave structure on the side facing the pipe beam 30, it is difficult to directly install the pipe beam 30. Therefore, the first connecting plate 13 and the second connecting plate 14 play an auxiliary role in the installation. The first connecting plate 13 and the second connecting plate 14 protrude outward toward the pipe beam 30, thereby facilitating the installation of the pipe beam 30.

[0046] In some embodiments, such as Figure 2 and Figure 3 As shown, the first connecting plate 13 and the second connecting plate 14 are respectively provided with mounting grooves 15 on the side facing the outer sill plate 20. The mounting grooves 15 are used to accommodate the ends of the pipe beam 30. The groove surface of the mounting groove 15 can play a positioning role for the pipe beam 30. The bottom surface of the mounting groove 15 is provided with mounting holes 16. The pipe beam 30 is provided with through holes 33. The through holes 33 are aligned with the mounting holes 16. The pipe beam 30 can be fixed in the mounting groove 15 by passing bolts through the through holes 33 and the mounting holes 16 in sequence, so as to ensure the connection strength between the two ends of the pipe beam 30 and the inner sill plate 10.

[0047] In some embodiments, such as Figure 2 and Figure 3 As shown, the first connecting plate 13 is positioned along the transverse X at the end of the frontmost beam 200 of the floor 300, and the second connecting plate 14 is positioned along the transverse X at the end of the rearmost beam 200 of the floor 300. Since the two ends of the beam 200 need to be connected by the first connecting plate 13 and the second connecting plate 14, the two ends of the beam 200 cannot be fitted with filler 40. However, the first connecting plate 13 and the second connecting plate 14 can compensate for the lack of filler 40. The first connecting plate 13 and the second connecting plate 14 can connect the end of the tube beam 30 to the inner sill plate 10, thereby connecting the beam 200 to ensure the integrity of the closed stress transmission path.

Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
