Detailed Implementation

[0019] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The following is for reference. Figures 1-3 The vehicle body structure according to an embodiment of the present invention is described.

[0021] like Figures 1-3 As shown, the vehicle body structure according to an embodiment of the present invention includes: a door sill beam, a first reinforcing component 20, and a second reinforcing component 30.

[0022] The door sill beam includes: an inner door sill plate 11 and an outer door sill plate 12, the inner door sill plate 11 and the outer door sill plate 12 being along the width direction of the vehicle (i.e., Figure 1 Corresponding to the Y direction shown, the outer sill plate 12 defines a first mounting space 121, and the inner sill plate 11 defines a second mounting space 111; a first reinforcing component 20 is disposed in the first mounting space 121 and connected to the outer sill plate 12, and a second reinforcing component 30 is disposed in the second mounting space 111 and connected to the inner sill plate 11, along the width direction of the vehicle (i.e., Figure 1 (As shown in the Y direction), the orthographic projection of the first reinforcing component 20 and the orthographic projection of the second reinforcing component 30 have an overlapping area.

[0023] Understandably, there are two door sill beams, spaced apart and symmetrically arranged along the width of the vehicle.

[0024] Among them, the inner sill plate 11 and the outer sill plate 12 are along the width direction of the vehicle (i.e., Figure 1 As shown in the Y direction, in some embodiments of this application, the vehicle body structure also includes a middle reinforcing plate. The inner sill plate 11 and the outer sill plate 12 are both connected to the middle reinforcing plate, and are arranged along the width direction of the vehicle (i.e., along the Y direction). Figure 1 The Y-direction shown corresponds to the setting.

[0025] The outer sill plate 12 defines a first mounting space 121, which opens toward the inner sill plate 11. The inner sill plate 11 defines a second mounting space 111, which opens toward the outer sill plate 12. A first reinforcing component 20 is disposed in the first mounting space 121 and is connected to the outer sill plate 12. In some embodiments of this application, the first reinforcing component 20 is connected to the outer sill plate 12 by welding. A second reinforcing component 30 is disposed in the second mounting space 111 and is connected to the inner sill plate 11. In some embodiments of this application, the second reinforcing component 30 is connected to the inner sill plate 11 by welding.

[0026] Along the width direction of the vehicle (i.e.) Figure 1 As shown in the Y direction), the orthographic projection of the first reinforcing component 20 and the orthographic projection of the second reinforcing component 30 have an overlapping area. That is to say, if a plane is defined, the width direction of the vehicle (i.e., Figure 1 The Y-direction shown is perpendicular to the plane, and the normal of the plane is perpendicular to the width direction of the vehicle (i.e., Figure 1 Parallel to the Y direction shown, the orthographic projection of the first reinforcing component 20 on this plane and the orthographic projection of the second reinforcing component 30 on this plane have overlapping areas.

[0027] It is understandable that the vehicle body structure of this application can significantly improve the structural strength of the vehicle body structure without changing the overall layout, simply by adding the first reinforcing component 20 and the second reinforcing component 30 inside the door sill beam. Moreover, the weight increase is low, the number of parts is small, and the process is simple, which is conducive to greatly reducing development costs and material costs.

[0028] The body structure of this application can achieve orderly absorption and transfer of collision energy, meet the requirements of national and European side pole impact regulations, has low intrusion, and the survival space meets the regulatory requirements. Moreover, it can achieve flexible switching between the national standard version and the European standard version of the same body structure. Domestically sold models do not need to install the above-mentioned reinforcement components to meet the national standard requirements, while models exported to Europe only need to add the above-mentioned reinforcement components to meet the European standard requirements. There is no need to develop two completely different body-in-whites, which is conducive to improving the universality and export adaptability of the body structure.

[0029] Therefore, by placing the first reinforcing component 20 in the first mounting space 121 and connecting it to the outer sill plate 12, and placing the second reinforcing component 30 in the second mounting space 111 and connecting it to the inner sill plate 11, and by ensuring that the orthographic projections of the first reinforcing component 20 and the second reinforcing component 30 overlap, the side impact performance of the vehicle body structure can be significantly improved, the degree of sill beam deformation caused by side impact can be reduced, the compression of the side panel on the occupant survival space can be reduced, and safety can be improved.

[0030] In some embodiments of the present invention, such as Figure 3 As shown, the sill outer panel 12 includes: a first outer panel 122, a second outer panel 123, and a third outer panel 124. The second outer panel 123 extends along the height direction of the vehicle. The ends of the first outer panel 122 and the third outer panel 124 away from the sill inner panel 11 are respectively connected to the two ends of the second outer panel 123 along the height direction of the vehicle, so as to jointly define the first installation space 121. The first reinforcing component 20 includes a first reinforcing member 21, which is connected to the first outer panel 122, the second outer panel 123, and the third outer panel 124. The dimension of the first reinforcing member 21 along the length direction of the vehicle is greater than the dimension along the height direction of the vehicle.

[0031] The sill outer panel 12 includes a first outer panel 122, a second outer panel 123, and a third outer panel 124, which are respectively connected and arranged. The second outer panel 123 is along the height direction of the vehicle (i.e., Figure 1Extending in the Z direction (as shown), the first outer plate 122 and the third outer plate 124 have an end near the inner sill plate 11 and an end away from the inner sill plate 11. The ends of the first outer plate 122 and the third outer plate 124 away from the inner sill plate 11 are connected to the two ends of the second outer plate 123 extending in the height direction. The first outer plate 122, the second outer plate 123, and the third outer plate 124 together define a first mounting space 121. As some embodiments of this application, the first outer plate 122, the second outer plate 123, and the third outer plate 124 are integrally formed.

[0032] The first reinforcing component 20 includes a first reinforcing member 21, which is connected to the first outer plate 122, the second outer plate 123, and the third outer plate 124. As some embodiments of this application, the first reinforcing member 21 includes a first sub-plate 22, a second sub-plate 23, and a third sub-plate 24. The second sub-plate 23 is along the height direction of the vehicle (i.e.,...). Figure 1 Extending in the Z direction (as shown), the ends of the first sub-plate 22 and the third sub-plate 24 away from the inner sill plate 11 are respectively connected to the second sub-plate 23 along the vehicle height direction (i.e., Figure 1 The two ends of the plate (in the Z direction shown) are connected, and the first sub-plate 22 is connected to the first outer plate 122, the second sub-plate 23 is connected to the second outer plate 123, and the third sub-plate 24 is connected to the first outer plate 122.

[0033] As some embodiments of this application, the first reinforcing member 21 has a C-shaped cross-section that is adapted to the cross-section of the outer sill plate 12.

[0034] The first reinforcing member 21 is larger in dimension along the length of the vehicle than in dimension along the height of the vehicle (i.e.) Figure 1 The dimensions shown are in the Z direction, meaning that the first reinforcing member 21 has dimensions along the length direction of the vehicle (i.e., Figure 1 The dimensions in the X direction (as shown) and along the height direction of the vehicle (i.e.) Figure 1 The dimensions of the first reinforcing member 21 in the Z direction (as shown) are along the length of the vehicle (i.e., Figure 1 The dimension in the X direction (as shown) is larger than that along the height direction of the vehicle (i.e. Figure 1 The dimension in the Z direction (as shown).

[0035] This design can improve the structural strength and stiffness of the sill outer panel 12, enhance its bending stiffness and cross-sectional stability, and ensure that the impact load on the sill outer panel 12 during a side collision can be evenly transferred to the first reinforcing member 21 and dispersed, reducing the risk of local load concentration. It can also disperse the Z and Y direction impact forces generated by the side collision, resist Z and Y direction deformation, and improve the compactness and bending performance of the vehicle body structure.

[0036] In some embodiments of the present invention, such as Figure 3As shown, the first reinforcing component 20 further includes a second reinforcing member 25. The first reinforcing member 21 defines a first subspace 211 that opens toward the inner sill plate 11. The second reinforcing member 25 is disposed within the first subspace 211 and connected to the first reinforcing member 21.

[0037] The first reinforcing member 21 defines a first subspace 211, which opens toward the inner door sill panel 11. A second reinforcing member 25 is disposed within the first subspace 211 and is connected to the first reinforcing member 21. Specifically, the second reinforcing member 25 extends along the height direction of the vehicle (i.e.,...). Figure 1 The second reinforcing member 25 has two opposing ends in the Z direction (as shown), and is along the height direction of the vehicle (i.e., along the Z direction). Figure 1 The two ends of the second reinforcing member 25 (in the Z direction shown) are respectively connected to the first reinforcing member 21, and the second reinforcing member 25 is along the width direction of the vehicle (i.e., Figure 1 The outer side (in the Y direction shown) is connected to the first reinforcing member 21.

[0038] In some embodiments of this application, the second reinforcing member 25 has an "L"-shaped cross-section. In some embodiments of this application, the second reinforcing member 25 is connected to the first reinforcing member 21 by welding.

[0039] By defining a first subspace 211 that opens toward the inner sill plate 11 by the first reinforcing member 21, and by placing the second reinforcing member 25 within the first subspace 211 and connecting it to the first reinforcing member 21, the structural strength and torsional stiffness of the first reinforcing assembly 20 can be further improved to resist the Z-direction deformation of the outer sill plate 12 during a side impact, thereby reducing the risk of excessive deformation of the outer sill plate 12 compressing the occupant survival space.

[0040] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the sill inner panel 11 includes: a first inner panel 112, a second inner panel 113, and a third inner panel 114. The second inner panel 113 is located along the height direction of the vehicle (i.e., Figure 1 Extending in the Z direction (as shown), the ends of the first inner panel 112 and the third inner panel 114 away from the outer sill panel 12 are respectively connected to the second inner panel 113 along the vehicle height direction (i.e., Figure 1 The two ends of the Z-direction shown are connected to jointly define the second installation space 111; The second reinforcing component 30 includes a third reinforcing member 31, which is connected to the first inner panel 112, the second inner panel 113, and the third inner panel 114, and the third reinforcing member 31 is along the length direction of the vehicle (i.e., Figure 1 The dimension in the X direction (as shown) is larger than that along the height direction of the vehicle (i.e. Figure 1 The dimension in the Z direction (as shown).

[0041] The sill inner panel 11 includes a first inner panel 112, a second inner panel 113, and a third inner panel 114, which are respectively connected and arranged. The second inner panel 113 is arranged along the height direction of the vehicle (i.e., Figure 1 Extending in the Z direction (as shown), the first inner plate 112 and the third inner plate 114 have an end near the outer sill plate 12 and an end away from the outer sill plate 12. The ends of the first inner plate 112 and the third inner plate 114 away from the inner sill plate 11 are connected to the two ends of the second inner plate 113 extending in the height direction. The first inner plate 112, the second inner plate 113, and the third inner plate 114 together define the second mounting space 111. As some embodiments of this application, the first inner plate 112, the second inner plate 113, and the third inner plate 114 are integrally formed.

[0042] The second reinforcing component 30 includes a third reinforcing member 31, which is connected to the first inner panel 112, the second inner panel 113, and the third inner panel 114. As some embodiments of this application, the third reinforcing member 31 includes a fourth sub-plate 32, a fifth sub-plate 33, a sixth sub-plate 34, a seventh sub-plate 35, and an eighth sub-plate 36. The fifth sub-plate 33 is located along the height direction of the vehicle (i.e.,...). Figure 1 Extending in the Z direction (as shown), the ends of the fourth sub-plate 32 and the sixth sub-plate 34 furthest from the outer sill plate 12 are respectively connected to the fifth sub-plate 33 along the vehicle height direction (i.e., Figure 1 The two ends of the fifth sub-plate 33 are connected along the length direction of the vehicle (i.e., the Z direction shown). Figure 1 The X-direction shown is connected to the seventh sub-plate 35 and the eighth sub-plate 36 respectively. The seventh sub-plate 35 is along the height direction of the vehicle (i.e., Figure 1 The Z-direction shown is connected to the fourth sub-plate 32 and the sixth sub-plate 34 respectively, and the eighth sub-plate 36 is along the height direction of the vehicle (i.e., Figure 1 The Z-direction shown is connected to the fourth sub-plate 32 and the sixth sub-plate 34 respectively. The fourth sub-plate 32 is connected to the first inner plate 112, the fifth sub-plate 33 is connected to the second inner plate 113, and the sixth sub-plate 34 is connected to the third inner plate 114.

[0043] As some embodiments of this application, the third reinforcing member 31 is constructed as a box-shaped bracket and is disposed in the second mounting space 111 of the inner sill plate 11, and the cross section of the third reinforcing member 31 is adapted to the cross section of the inner sill plate 11.

[0044] The third reinforcing member 31 is along the length direction of the vehicle (i.e.) Figure 1 The dimension in the X direction (as shown) is larger than that along the height direction of the vehicle (i.e. Figure 1 The dimensions shown are in the Z direction, meaning that the third reinforcing member 31 has dimensions along the length direction of the vehicle (i.e., Figure 1 The dimensions in the X direction (as shown) and along the height direction of the vehicle (i.e.) Figure 1The dimensions of the third reinforcing member 31 in the Z direction (as shown) are along the length of the vehicle (i.e., Figure 1 The dimension in the X direction (as shown) is larger than that along the height direction of the vehicle (i.e. Figure 1 The dimension in the Z direction (as shown).

[0045] This design can improve the structural strength and stiffness of the inner sill plate 11, enhance its bending stiffness and cross-sectional stability, and ensure that the impact load on the inner sill plate 11 during a side pillar collision can be evenly transferred to the third reinforcing member 31 and dispersed, reducing the risk of local load concentration. It can also disperse the Y and Z direction impact forces generated by the side pillar collision, resist Z and Y direction deformation, and improve the compactness and bending performance of the vehicle body structure.

[0046] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the second reinforcing component 30 includes: a fourth reinforcing member 37, a third reinforcing member 31 defining a second subspace 311 that opens toward the outer sill plate 12, the fourth reinforcing member 37 being disposed within the second subspace 311 and connected to the third reinforcing member 31.

[0047] The third reinforcing member 31 defines a second subspace 311, which opens toward the outer door sill panel 12. A fourth reinforcing member 37 is disposed within the second subspace 311 and is connected to the third reinforcing member 31. In some embodiments of this application, the fourth reinforcing member 37 is positioned along the width direction of the vehicle (i.e.,...). Figure 1 The Y-direction shown has two opposite ends, along the width direction of the vehicle (i.e., Figure 1 (as shown in the Y direction), the two opposite ends of the fourth reinforcing member 37 are connected to the third reinforcing member 31 and the intermediate reinforcing plate, respectively. The fourth reinforcing member 37 is along the length direction of the vehicle (i.e., Figure 1 The two ends of the fourth reinforcing member 37 (in the X direction shown) are connected to the seventh sub-plate 35 and the eighth sub-plate 36, respectively. In some embodiments of this application, the cross-sectional structure of the fourth reinforcing member 37 is "Z" shaped. In some embodiments of this application, the fourth reinforcing member 37 is connected to the third reinforcing member 31 by welding.

[0048] By defining a second subspace 311 that opens toward the outer sill plate 12 with the third reinforcement 31, and by placing the fourth reinforcement 37 within the second subspace 311 and connecting it to the third reinforcement 31, the structural strength and torsional stiffness of the second reinforcement assembly 30 can be further improved to resist the Z-direction and Y-direction deformation of the outer sill plate 12 during a side impact, thereby reducing the risk of excessive deformation of the inner sill plate 11 compressing the occupant survival space.

[0049] In some embodiments of the present invention, such as Figure 1 and Figure 2As shown, the second reinforcing component 30 includes a fifth reinforcing member 38, which is connected to the first inner panel 112, the second inner panel 113, and the third inner panel 114, along the length direction of the vehicle (i.e., Figure 1 (As shown in the X direction), the fifth reinforcing member 38 and the third reinforcing member 31 are arranged together.

[0050] As some embodiments of this application, the fifth reinforcing member 38 is along the height direction of the vehicle (i.e. Figure 1 The fifth reinforcing member 38 (shown in the Z direction) has two opposing ends. Its two ends are respectively welded to the first inner plate 112 and the third inner plate 114, along the width direction of the vehicle (i.e., Figure 1 (As shown in the Y direction), the fifth reinforcing member 38 is connected to the second inner panel 113 on the side closest to the inside of the vehicle. Along the length direction of the vehicle (i.e., Figure 1 (As shown in the X direction), the fifth reinforcing member 38 and the third reinforcing member 31 are arranged together.

[0051] As some embodiments of this application, there are multiple fifth reinforcing members 38, and the multiple fifth reinforcing members 38 are along the length direction of the vehicle (i.e., Figure 1 The X-direction (as shown) is arranged at intervals.

[0052] This configuration enables the fifth reinforcing member 38 to uniformly transfer the Y-direction and Z-direction impact loads generated by the side impact to the inner sill plate 11, which can significantly improve the ability of the inner sill plate 11 to resist Y-direction and Z-direction deformation.

[0053] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the vehicle's body structure also includes: a front floor 40, a rear crossbeam 41 behind the front seats, and a reinforcing beam 42. The reinforcing beam 42 is located on the front floor 40, and the rear crossbeam 41 behind the front seats covers the reinforcing beam 42 and is connected to the front floor 40. The reinforcing beam 42 extends along the width direction of the vehicle (i.e.,...). Figure 1 It extends in the Y direction as shown and its two ends are respectively connected to the inner sill plates 11 of the two sill beams.

[0054] Among them, the reinforcing beam 42 is provided on the front floor 40. As some embodiments of this application, the reinforcing beam 42 is provided on the front floor 40 by bolt connection. The rear crossbeam 41 of the front seat is covered on the reinforcing beam 42. Furthermore, the rear crossbeam 41 of the front seat is connected to the front floor 40. As some embodiments of this application, the rear crossbeam 41 of the front seat is connected to the reinforcing beam 42 by bolt connection, and the rear crossbeam 41 of the front seat is connected to the front floor 40 by welding.

[0055] Reinforcing beam 42 is along the width direction of the vehicle (i.e.) Figure 1 The reinforcing beam 42 extends along the width direction of the vehicle (i.e., the Y direction shown), and the reinforcing beam 42 extends along the width direction of the vehicle (i.e., the Y direction shown). Figure 1 The two ends of the reinforcing beam 42 (in the Y direction shown) are respectively connected to the inner sill plates 11 of the two sill beams. As some embodiments of this application, the reinforcing beam 42 is along the width direction of the vehicle (i.e., Figure 1 The two ends of the Y-direction shown are respectively connected to the inner sill plates 11 of the two sill beams on the left and right sides of the vehicle by welding.

[0056] This configuration allows the Y-axis impact force on the sill beam on the impact side to be directly transmitted to the reinforcing beam 42 via the inner sill plate 11 during a side collision, and then from the reinforcing beam 42 to the sill beam on the non-collision side, forming a complete Y-axis force transmission path. This reduces the Y-axis deformation after a collision and provides passengers with ample survival space.

[0057] In some embodiments of the invention, the reinforcing beam 42 is formed with a plurality of beams along the width direction of the vehicle (i.e., Figure 1 A cavity extending in the Y direction (as shown), multiple cavities along the length direction of the vehicle (i.e., Figure 1 (as shown in the X direction) arranged at intervals.

[0058] As some embodiments of this application, the reinforcing beam 42 is formed with two beams along the width direction of the vehicle (i.e., Figure 1 The cavity extends along the Y direction (as shown), and the two cavities are along the length direction of the vehicle (i.e., Figure 1 (as shown in the X direction) arranged at intervals.

[0059] This configuration can improve the structural strength and torsional stiffness of the reinforcing beam 42, so that the reinforcing beam 42 can absorb energy through cavity collapse after the collision, and can form a continuous and uninterrupted force transmission channel in the Y direction, which is beneficial to reducing the Y-direction deformation after the collision.

[0060] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, along the width direction of the vehicle (i.e. Figure 1 (As shown in the Y direction), the orthographic projection of the reinforcing beam 42 and the orthographic projection of the third reinforcing member 31 have an overlapping area.

[0061] In other words, a plane is defined that is parallel to the width direction of the vehicle (i.e., Figure 1 The plane is perpendicular to the Y-direction shown, and its normal is perpendicular to the width direction of the vehicle (i.e., the Y-direction shown). Figure 1 Parallel to the Y-direction shown, the orthographic projection of the reinforcing beam 42 on this plane coincides with the orthographic projection of the third reinforcing member 31 on this plane.
