[0031] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which 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 drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0032] Reference will be made below to Figures 1 - 5 describe the vehicle body structure 100 according to the first aspect embodiment of the present invention.
[0033] As Figures 1 - 4 shown, the vehicle body structure 100 according to the first aspect embodiment of the present invention includes: a door ring reinforcement plate 10 and a lower hinge reinforcement plate 20.
[0034] Specifically, the door ring reinforcement plate 10 is formed by enclosing an A-pillar reinforcement section 11, a sill reinforcement section 12, a B-pillar reinforcement section 13, and an upper side reinforcement section 14 of the side panel. The lower hinge reinforcement plate 20 is disposed at the lower part of the A-pillar reinforcement section 11, and a first reinforcing rib 21 is formed on the lower hinge reinforcement plate 20, and the first reinforcing rib 21 extends in the front-rear direction of the vehicle.
[0035] Among them, the door ring reinforcement plate 10 is arranged between the inner side panel and the outer side panel. Specifically, the A-pillar reinforcement section 11 is arranged in the A-pillar 30, the sill reinforcement section 12 is arranged in the sill 31, the B-pillar reinforcement section 13 is arranged in the B-pillar 32, and the upper side panel reinforcement section 14 is arranged in the roof side rail 33. The lower hinge reinforcement plate 20, the A-pillar reinforcement section 11 and the position where the A-pillar 30 installs the door lower hinge are fixedly connected, so as to strengthen the structural strength of the position where the A-pillar 30 installs the door lower hinge and improve the structural stability of the door on the vehicle body.
[0036] It can be understood that the door ring reinforcement plate 10 is an integral part. During the assembly process, the operator has fewer operation steps, which can reduce the assembly difficulty and improve the assembly efficiency. After the assembly is completed, the A-pillar reinforcement section 11 and the lower hinge reinforcement plate 20 can provide support for the A-pillar 30 inside the A-pillar 30, thereby improving the structural strength of the A-pillar 30.
[0037] During the driving of the vehicle, when the A-pillar 30 is impacted, the A-pillar reinforcement section 11 and the lower hinge reinforcement plate 20 can bear the impact together with the A-pillar 30 inside the A-pillar 30. The impact force can be transmitted between the various reinforcement sections of the door ring reinforcement plate 10 and the lower hinge reinforcement plate 20, so that the impact force is dispersed, thereby improving the impact resistance of the A-pillar 30.
[0038] During the driving of the vehicle, the impact force in the front-rear direction is often relatively large. When the vehicle is collided in the front-rear direction, especially in the case of an offset collision in the front-rear direction, a large impact force will act on the A-pillar 30. In this embodiment, by providing the first reinforcing rib 21 extending in the front-rear direction on the lower hinge reinforcement plate 20, when the A-pillar 30 is impacted in the front-rear direction, the first reinforcing rib 21 can share a part of the impact force in the front-rear direction, improve the bearing capacity of the A-pillar 30 for the impact in the front-rear direction, thereby further improving the impact resistance of the A-pillar 30 and enhancing the safety of the vehicle.
[0039] For the vehicle body structure 100 according to the first aspect embodiment of the present invention, on the one hand, the assembly difficulty can be reduced, and on the other hand, the impact resistance of the A-pillar 30 can be improved, thereby improving the safety of the vehicle.
[0040] In some embodiments of the present invention, such as Figure 3 and Figure 5As shown, the vehicle body structure 100 further includes an A-pillar 30. The A-pillar 30 includes an inner A-pillar panel 34 and an outer A-pillar panel (not shown in the drawings) arranged inside and outside. An A-pillar reinforcement section 11 is provided between the inner A-pillar panel 34 and the outer A-pillar panel. The lower hinge reinforcement plate 20 is formed with a folded edge that folds towards the inner A-pillar panel 34, and the folded edge is connected to the inner A-pillar panel 34. In this way, the folded edge can provide support inside the A-pillar 30, further enhancing the structural strength of the A-pillar 30. When the A-pillar 30 is impacted, the folded edge can also share part of the impact force, thereby further improving the impact resistance of the A-pillar 30.
[0041] In some embodiments of the present utility model, as Figure 3 shown, the folded edge includes: a first folded edge 22 and a second folded edge 23. The front side edge of the lower hinge reinforcement plate 20 is bent to form the first folded edge 22, and the upper side edge of the lower hinge reinforcement plate 20 is bent to form the second folded edge 23. It can be understood that the impact force from the front of the vehicle has a greater impact on the A-pillar 30, and the side impact on the A-pillar 30 from the outside to the inside has a greater impact on the safety of the occupants inside the vehicle. By providing the first folded edge 22 at the front side edge of the lower hinge reinforcement plate 20, and connecting the first folded edge 22 to the front side of the inner A-pillar panel 34, the structural strength of the front side of the inner A-pillar panel 34 can be improved. By providing the second folded edge 23 at the upper side edge of the hinge reinforcement plate, when a collision occurs at the side front of the vehicle, the second folded edge 23 can reduce the deformation of the A-pillar 30 in the left-right direction, thereby reducing the probability of the deformation of the A-pillar 30 invading the occupant compartment. Thus, the safety of the vehicle can be further improved. Among them, preferably, the first folded edge 22 is bolted to the inner A-pillar panel 34.
[0042] In some embodiments of the present utility model, as Figure 3 shown, the second folded edge 23 is formed with a connecting folded edge 231 that folds upwards, and the second folded edge 23 is connected to the inner A-pillar panel 34 through the connecting folded edge 231. By providing the connecting folded edge 231, it is convenient to realize the connection between the second folded edge 23 and the inner A-pillar panel 34, and the connecting folded edge 231 can increase the contact area between the second folded edge 23 and the inner A-pillar panel 34, thereby improving the connection strength between the second folded edge 23 and the inner A-pillar panel 34. Among them, preferably, the connecting folded edge 231 and the inner A-pillar panel 34 are welded.
[0043] In some embodiments of the present utility model, the A-pillar reinforcement section 11 is fixedly connected between the lower hinge reinforcement plate 20 and the outer A-pillar panel. In this way, during the production process, the probability of the lower hinge reinforcement plate 20 interfering with the door ring reinforcement plate 10 is relatively low, thereby reducing the production difficulty.
[0044] The A-pillar strengthening section 11 is welded to the lower hinge reinforcing plate 20. The welding connection has relatively high strength and reliability. By welding the A-pillar strengthening section 11 and the lower hinge reinforcing plate 20, it is easier to make the connection strength between the A-pillar strengthening section 11 and the lower hinge reinforcing plate 20 meet the design requirements.
[0045] In some embodiments of the present utility model, as Figures 2 - 4 shown, a groove 111 is formed on the A-pillar strengthening section 11, the lower hinge reinforcing plate 20 is disposed in the groove 111, a third folded edge 24 that is folded inward is formed on the lower hinge reinforcing plate 20, and the third folded edge 24 is connected to the side wall of the groove 111. By providing the groove 111, the groove 111 can increase the structural strength of the door ring reinforcing plate 10, thereby further improving the structural strength of the A-pillar 30, and the groove 111 can increase the connection area between the lower hinge reinforcing plate 20 and the A-pillar strengthening section 11, thereby increasing the connection strength between the lower hinge reinforcing plate 20 and the A-pillar strengthening section 11. By providing the third folded edge 24, the connection area between the lower hinge reinforcing plate 20 and the A-pillar strengthening section 11 can be further increased, thereby further increasing the connection strength between the lower hinge reinforcing plate 20 and the A-pillar strengthening section 11.
[0046] In some embodiments of the present utility model, as Figure 3 shown, there are multiple first reinforcing ribs 21. For example, the first reinforcing ribs 21 can be two, three, or four. The multiple first reinforcing ribs 21 are arranged at intervals in the up-and-down direction of the vehicle. A second reinforcing rib 25 is further formed on the lower hinge reinforcing plate 20. The second reinforcing rib 25 extends in the up-and-down direction of the vehicle and is disposed between two adjacent first reinforcing ribs 21. By providing the second reinforcing rib 25, the anti-impact ability of the lower hinge reinforcing plate 20 in the up-and-down direction can be improved. Thus, the anti-impact ability of the A-pillar 30 in the up-and-down direction can be improved, thereby further improving the anti-impact ability of the A-pillar 30.
[0047] In some embodiments of the present utility model, as Figure 2 shown, the lower hinge reinforcing plate 20 includes a first strengthening section 26 and a second strengthening section 27. The first strengthening section 26 extends in the up-and-down direction of the vehicle. The second strengthening section 27 is connected to the lower end of the first strengthening section 26 and extends backward in the front-rear direction of the vehicle. The first strengthening section 26 is disposed on the A-pillar strengthening section 11, and the second strengthening section 27 is disposed on the sill strengthening section 12. When the A-pillar 30 is impacted, the impact force on the A-pillar 30 will be transmitted to the sill 31. By disposing the second strengthening section 27 on the sill strengthening section 12, the anti-impact ability of the sill 31 can be improved, thereby further improving the safety of the vehicle.
[0048] In some embodiments of the present utility model, as Figure 2As shown, the vehicle body structure 100 further includes: an upper hinge reinforcement plate 40, which is provided at the upper part of the A-pillar reinforcement section 11. Among them, the upper hinge reinforcement plate 40, the A-pillar reinforcement section 11, and the position where the A-pillar 30 installs the door upper hinge are fixedly connected, thereby strengthening the structural strength of the position where the A-pillar 30 installs the door upper hinge, and further improving the structural stability of the door on the vehicle body. In addition, the upper hinge reinforcement plate 40 can also provide support for the A-pillar 30 inside the A-pillar 30 and share the impact force received by the A-pillar 30, thereby further improving the impact resistance of the A-pillar 30.
[0049] In some embodiments of the present invention, as Figure 2 shown, the vehicle body structure 100 further includes: a sill support plate 50 and a sill reinforcement plate 60. The sill support plate 50 is provided at the sill reinforcement section 12, and the sill reinforcement plate 60 is connected between the sill reinforcement section 12 and the B-pillar reinforcement section 13. By providing the sill support plate 50 and the sill reinforcement plate 60, the structural strength of the sill 31 can be improved, thereby further improving the impact resistance of the vehicle.
