Furthermore, reference numerals and / or letters may be repeated in different examples.

[0036] The vehicle body structure 100 according to a first aspect embodiment of the present invention is described below with reference to the accompanying drawings.

[0037] like Figures 1 to 3 As shown, the vehicle body structure 100 according to the first aspect embodiment of the present invention includes: an A-pillar 1 and a B-pillar 2. The upper end of the B-pillar 2 is connected to the A-pillar 1. The B-pillar 2 includes an outer B-pillar panel 21, an inner B-pillar panel 22, and an inner B-pillar panel reinforcing plate 23. The inner B-pillar panel 22 is disposed inside the outer B-pillar panel 21. A first cavity is defined between the inner B-pillar panel 22 and the outer B-pillar panel 21. The inner B-pillar panel reinforcing plate 23 includes at least a first portion 231 located between the inner B-pillar panel 22 and the outer B-pillar panel 21. At least a portion of the first portion 231 is disposed within the first cavity to divide the first cavity into at least three first sub-cavities 24. Since B-pillar 2 is supported on the lower side of A-pillar 1, in the top-compression test, the force is applied to B-pillar 2 through A-pillar 1. By setting multiple first sub-cavities 24 in B-pillar 2, the rigidity of B-pillar 2 can be improved to enhance its resistance to deformation during the top-compression process. At the same time, the deformation of B-pillar 2 after impact can be reduced, thereby improving the collision performance of the vehicle body structure 100 and enhancing its safety.

[0038] According to the first aspect embodiment of the present invention, the vehicle body structure 100 can improve the rigidity of the B-pillar 2 by providing a plurality of first sub-cavities 24 in the B-pillar 2, thereby improving the B-pillar 2's resistance to deformation during the top pressure process. At the same time, it can reduce the deformation amplitude of the B-pillar 2 after bearing an impact, thereby improving the collision performance of the vehicle body structure 100 and enhancing the safety of the vehicle body structure 100.

[0039] In a specific example, such as Figure 3 As shown, multiple first sub-cavities 24 are distributed horizontally. That is, the B-pillar 2 has multiple first sub-cavities 24 extending vertically and distributed horizontally. This enhances the structural strength of the B-pillar 2 by improving the effect of the multiple first sub-cavities 24.

[0040] According to an embodiment of the present invention, the first part 231 and the inner panel of the B-pillar have a first connection point 25, a second connection point 26 and a third connection point 27 arranged sequentially in the front-rear direction. The first part 231 and the inner panel of the B-pillar define a first sub-cavity 24 located between the first connection point 25 and the second connection point 26 and a first sub-cavity 24 located between the second connection point 26 and the third connection point 27. The first part 231 and the outer panel of the B-pillar define a first sub-cavity 24. The second connection point 26 is located in the first cavity.

[0041] In other words, in the front-rear direction, the portion of the first part 231 located between the first connection point 25 and the second connection point 26, together with the portion of the B-pillar inner panel 22 located between the first connection point 25 and the second connection point 26, jointly define a first sub-cavity 24; the portion of the first part 231 located between the second connection point 26 and the third connection point 27, together with the portion of the B-pillar inner panel 22 located between the second connection point 26 and the third connection point 27, jointly define a first sub-cavity 24, and the two first sub-cavities 24 defined by the first part 231 and the B-pillar inner panel 22 are arranged in the front-rear direction; the portion of the first part 231 located between the first connection point 25 and the third connection point 27, together with the portion of the B-pillar outer panel 21 located between the first connection point 25 and the third connection point 27, jointly define a first sub-cavity 24 located on the side of the first part 231 opposite to the B-pillar inner panel 22. Therefore, by setting the first connection point 25, the second connection point 26 and the third connection point 27, while ensuring that at least three first sub-cavities 24 are formed inside the B-pillar 2, the connection position between the first part 231 and the inner plate 22 of the B-pillar can be increased, thereby improving the strengthening effect of the inner plate reinforcing plate 23 of the B-pillar on the inner plate 22 of the B-pillar, so as to improve the overall rigidity of the B-pillar 2 structure.

[0042] According to some embodiments of the present invention, the first part 231 includes a first main body 2311, a first connecting part 2312, and a second connecting part 2313. The first main body 2311 is U-shaped and opens toward the outer panel 21 of the B-pillar. The first connecting part 2312 and the second connecting part 2313 are respectively connected to the front and rear ends of the first main body 2311. The first connecting part 2312 is sandwiched between the front end of the inner panel 22 of the B-pillar and the front end of the outer panel 21 of the B-pillar, and the first connecting part 2312 is connected to both the front end of the inner panel 22 of the B-pillar and the front end of the outer panel 21 of the B-pillar. The connection point between the first connecting part 2312 and the front end of the B-pillar inner panel 22 constitutes the first connection point 25. The second connecting part 2313 is sandwiched between the rear end of the B-pillar inner panel 22 and the rear end of the B-pillar outer panel 21, and the second connecting part 2313 is connected to both the rear end of the B-pillar inner panel 22 and the rear end of the B-pillar outer panel 21. The connection point between the second connecting part 2313 and the rear end of the B-pillar inner panel 22 constitutes the third connection point 27. The first main body 2311 is connected to the B-pillar inner panel 22, and the connection point between the first main body 2311 and the B-pillar inner panel 22 constitutes the second connection point 26.

[0043] In other words, the first part 231 is connected to both the inner B-pillar panel 22 and the outer B-pillar panel 21. The first connecting part 2312, sandwiched between the inner B-pillar panel 22 and the outer B-pillar panel 21, and the second connecting part 2313, sandwiched between the inner B-pillar panel 22 and the outer B-pillar panel 21, increase the number of connection points between the first part 231 and the inner and outer B-pillar panels 22 and 21, thereby enhancing the strengthening effect of the inner B-pillar panel reinforcement plate 23 on the overall B-pillar structure. Furthermore, the first main body 2311 has a U-shaped cross-section in the vertical direction that opens towards the outer B-pillar panel 21, i.e., towards the outer side of the vehicle body structure 100. This facilitates the connection between the first main body 2311 and the inner B-pillar panel 22. Simultaneously, by complicating the cross-sectional shape of the first part 231, the structural strength of the inner B-pillar panel reinforcement plate 23 can be increased, thus enhancing the strengthening effect on the B-pillar.

[0044] According to some embodiments of this utility model, such as Figure 4 As shown, the lower end of the B-pillar has a crumple zone 28, and the lower end of the B-pillar inner panel reinforcement plate 23 is higher than the crumple zone 28. That is, the B-pillar inner panel reinforcement plate 23 is positioned above the crumple zone 28. Therefore, while ensuring the reinforcement effect of the B-pillar inner panel reinforcement plate 23 on the B-pillar inner panel 22, it avoids the B-pillar inner panel reinforcement plate 23 affecting the deformation of the crumple zone 28. In other words, it ensures that the crumple zone 28 can properly crumple and absorb energy to buffer the impact force, thereby reducing the injury to occupants within the vehicle body structure 100.

[0045] According to some embodiments of this utility model, such as Figure 5As shown, pillar A1 includes an outer upper panel 11 and an inner upper panel 12. The inner upper panel 12 is located inside the outer upper panel 11, defining a second cavity between the inner upper panel 12 and the outer upper panel 11. The second cavity is located above the first cavity. The inner panel reinforcement plate 23 of pillar B also includes a second portion 232 located between the inner upper panel 12 and the outer upper panel 11. At least a portion of the second portion 232 is located within the second cavity to divide the second cavity into at least three second sub-cavities 13. The multiple second sub-cavities 13 are arranged in the vertical and / or horizontal directions. In other words, through the cooperation of the inner upper panel 12, the outer upper panel 11, and the second portion 232 of the inner panel reinforcement plate 23 of pillar B, multiple second sub-cavities 13 extending in the front-rear direction and arranged in the vertical and / or horizontal directions can be formed at the connection position between pillar A1 and pillar B2. Therefore, the connection between A-pillar 1 and B-pillar 2 can be increased to improve the stability of the connection between A-pillar 1 and B-pillar 2. At the same time, the strength of the connection between A-pillar 1 and B-pillar 2 can be strengthened to improve the rigidity of the connection between A-pillar 1 and B-pillar 2, thereby improving the overall stability and safety of the vehicle body structure 100.

[0046] According to some embodiments of the present invention, the second part 232 and the inner panel 12 of the A-pillar have a fourth connection point 14, a fifth connection point 15 and a sixth connection point 16 arranged sequentially from top to bottom. The second part 232 and the inner panel 12 of the A-pillar define a second sub-cavity 13 located between the fourth connection point 14 and the fifth connection point 15 and a second sub-cavity 13 located between the fifth connection point 15 and the sixth connection point 16. The second part 232 and the outer panel 11 of the A-pillar define a second sub-cavity 13. The fifth connection point 15 is located in the second cavity.

[0047] In other words, in the vertical direction, the portion of the second part 232 located between the fourth connection point 14 and the fifth connection point 15, together with the portion of the inner panel 12 on the A-pillar located between the fourth connection point 14 and the fifth connection point 15, jointly define a second sub-cavity 13; the portion of the second part 232 located between the fifth connection point 15 and the sixth connection point 16, together with the portion of the inner panel 12 on the A-pillar located between the fifth connection point 15 and the sixth connection point 16, jointly define a second sub-cavity 13, and the two second sub-cavities 13 defined by the second part 232 and the inner panel 12 on the A-pillar are arranged in the front-back direction; the portion of the second part 232 located between the fourth connection point 14 and the sixth connection point 16, together with the portion of the outer panel 11 on the A-pillar located between the fourth connection point 14 and the sixth connection point 16, jointly define a second sub-cavity 13 located on the side of the second part 232 opposite to the inner panel 12 on the A-pillar. Therefore, by setting the fourth connection point 14, the fifth connection point 15 and the sixth connection point 16, while ensuring that at least three second sub-cavities 13 are formed inside the B-pillar 2, the connection position between the second part 232 and the inner plate 12 of the A-pillar can be increased to improve the rigidity of the connection position between the A-pillar and the B-pillar.

[0048] According to some embodiments of the present invention, the second part 232 includes a second main body 2321, a third connecting part 2322, and a fourth connecting part 2323. The third connecting part 2322 and the fourth connecting part 2323 are respectively connected to the upper and lower ends of the second main body 2321. The third connecting part 2322 is sandwiched between the upper end of the outer panel 11 of the A-pillar and the upper end of the inner panel 12 of the A-pillar, and the third connecting part 2322 is connected to both the upper end of the outer panel 11 and the upper end of the inner panel 12 of the A-pillar. The connection point between the third connecting part 2322 and the inner panel 12 of the A-pillar constitutes the fourth connection point 1. 4. The upper end of the inner panel 22 of the B-pillar is sandwiched between the fourth connecting part 2323 and the lower end of the inner panel 12 of the A-pillar. The upper end of the inner panel 22 of the B-pillar is connected to both the fourth connecting part 2323 and the lower end of the inner panel 12 of the A-pillar. The connection position between the fourth connecting part 2323 and the inner panel 22 of the B-pillar forms the sixth connection point 16. The second main body 2321 is located in the second cavity. In the vertical direction, the middle part of the side of the second main body 2321 away from the outer panel 11 of the A-pillar is connected to the inner panel 12 of the A-pillar. The connection point between the second main body 2321 and the inner panel 12 of the A-pillar forms the fifth connection point 15.

[0049] In other words, the second part 232 is connected to the inner panel 12 of the A-pillar, the outer panel 11 of the A-pillar, and the inner panel 22 of the B-pillar. Specifically, the portion of the third connecting part 2322 sandwiched between the inner panel 12 and the outer panel 11 of the A-pillar increases the connection points between the second part 232 and the inner and outer panels 12 of the A-pillar. Similarly, the portion of the inner panel 22 of the B-pillar sandwiched between the fourth connecting part 2323 and the lower end of the inner panel 12 of the A-pillar increases the connection points between the inner panel 22 of the B-pillar, the inner panel 12 of the A-pillar, and the second part 232. This also creates a continuous path between the B-pillar and the inner panel 12 of the A-pillar, thereby improving the structural strength at the connection between the A-pillar and the B-pillar.

[0050] According to some embodiments of this utility model, such as Figure 6 As shown, the vehicle body structure 100 includes a sill 3, and the lower end of the B-pillar 2 is connected to the sill 3, that is, the B-pillar 2 is supported between the sill 3 and the A-pillar 1. The sill 3 includes an outer sill plate 31, an inner sill plate 32 and a sill reinforcement plate 33. The upper end of the sill reinforcement plate 33 is connected to the upper end of the inner sill plate 32, and the lower end of the sill reinforcement plate 33 is connected to the lower ends of the inner sill plate 32 and the outer sill plate 31. There is a seventh connection point 34 between the sill reinforcement plate 33 and the outer sill plate 31, located in the middle of the vertical direction of the sill reinforcement plate 33. The sill reinforcement plate 33 and the outer sill plate 31 define a third cavity 35 and a fourth cavity 36 located on the upper and lower sides of the seventh connection point 34, respectively. In other words, the portion of the sill reinforcement plate 33 above the seventh connection point 34 and the portion of the outer sill plate 31 above the seventh connection point 34 together define the third cavity 35 above the seventh connection point 34. Similarly, the portion of the sill reinforcement plate 33 below the seventh connection point 34 and the portion of the outer sill plate 31 below the seventh connection point 34 together define the third cavity 35 below the seventh connection point 34. This effectively increases the number of cavities at the sill 3, thereby improving the sill 3's resistance to deformation. For example, in a pole impact test, by providing at least the third cavity 35 and the fourth cavity 36 within the sill 3, the deformation of the sill 3 towards the interior of the vehicle body structure 100 after an impact can be reduced, thus improving the collision performance of the vehicle body structure 100 and enhancing its safety. Furthermore, it effectively increases the fixing position of the sill reinforcement plate 33, ensuring the stability of the sill reinforcement plate 33 after installation.

[0051] According to some embodiments of this utility model, the sill 3 further includes an inner sill plate reinforcing plate 37, which defines a fifth cavity between the inner sill plate 32 and the reinforcing plate 33. The inner sill plate reinforcing plate 37 is disposed on the inner sill plate 32 and located within the fifth cavity. Therefore, by providing the inner sill plate reinforcing plate 37 within the fifth cavity, the deformation resistance of the fifth cavity can be improved. For example, the inner sill plate reinforcing plate 37 can divide the fifth cavity into multiple cavities, thereby improving the structural strength of the sill 3 and enhancing its post-impact performance.

[0052] According to some embodiments of this utility model, the sill inner panel 32 and the sill reinforcing plate 33 are respectively connected to the inner and outer sides of the lower end of the B-pillar inner panel 22. The lower end of the B-pillar inner panel 22 divides the fifth cavity into an inner cavity 38 and an outer cavity 39 located on the inner and outer sides of the B-pillar inner panel 22. That is, the lower end of the B-pillar inner panel 22 is sandwiched between the sill inner panel 32 and the sill reinforcing plate 33. Through the cooperation of the B-pillar inner panel 22 with the sill inner panel 32 and the sill reinforcing plate 33, the number of cavities extending in the front-rear direction on the sill 3 can be increased, thereby improving the pillar impact performance of the sill 3. In addition, the connection between the B-pillar 2 and the sill 3 can be strengthened to improve the overall stability and safety of the vehicle body structure 100.

[0053] Furthermore, a sill inner panel reinforcing plate 37 is disposed within the inner cavity 38, dividing the inner cavity 38 into multiple third sub-cavities 321, which are arranged vertically. In other words, the sill 3 also has multiple third sub-cavities 321 extending longitudinally and arranged vertically. This effectively increases the number of cavities within the sill 3, thereby reducing the deformation amplitude of the sill 3 upon impact with a pillar, thus improving its pillar impact performance. Additionally, it strengthens the connection between the B-pillar 2 and the sill 3, enhancing the overall stability and safety of the vehicle body structure 100.

[0054] In a specific example, the lower end of the B-pillar inner panel 22 is sandwiched between the lower end of the sill inner panel 32 and the lower end of the sill reinforcement plate 33, and is connected to both the lower ends of the sill inner panel 32 and the lower ends of the sill reinforcement plate 33. The upper ends of the sill inner panel 32 and the upper ends of the sill reinforcement plate 33 are located on the inner and outer sides of the B-pillar inner panel 22 and are connected to the B-pillar inner panel 22. This increases the connection points between the B-pillar inner panel 22 and the sill 3, thereby improving the rigidity of the connection points between the B-pillar 2 and the sill 3.

[0055] According to some embodiments of the present invention, the inner sill plate reinforcing plate 37 has an inwardly open U-shaped cross section in the front-back direction. The inner sill plate reinforcing plate 37 is located in the middle of the fifth cavity in the vertical direction and includes a first side plate 371, a second side plate 372 and a third side plate 373. The first side plate 371 is located above the second side plate 372. The ends of the first side plate 371 and the second side plate 372 that are away from the sill plate reinforcing plate 33 are connected to the inner sill plate 32. The ends of the first side plate 371 and the second side plate 372 that are close to the sill plate reinforcing plate 33 are connected through the third side plate 373.

[0056] Here, "opening inwards" refers to opening towards the direction away from the inner panel 22 of the B-pillar. That is, the outer ends of the first side panel 371 and the second side panel 372 are respectively connected to the upper and lower ends of the third side panel 373, and the first side panel 371 and the second side panel 372 are spaced apart from the upper and lower side walls of the fifth cavity. Thus, the fifth cavity can be divided into multiple cavities by the inner sill reinforcement plate 37. This effectively improves the structural strength of the sill 3, thereby enhancing its column impact resistance.

[0057] Specifically, the sill inner panel reinforcement plate 37 and the sill inner panel 32 define a third sub-cavity 321 located above the first side panel 371, a third sub-cavity 321 located between the first side panel 371 and the second side panel 372, and a third sub-cavity 321 located below the second side panel 372. In other words, the first side panel 371 and the second side panel 372 can divide the inner cavity 38 into three third sub-cavities 321 arranged in the vertical direction. Thus, the sill inner panel reinforcement plate 37 is U-shaped, which can reduce the difficulty of dividing the inner cavity 38 into three third cavities 35. Moreover, the size of the sill inner panel reinforcement plate 37 is small, which can reduce the installation difficulty of the sill inner panel reinforcement plate 37 and reduce the impact of the sill inner panel reinforcement plate 37 on the overall weight of the vehicle body structure 100.

[0058] According to some embodiments of this utility model, the vehicle body structure 100 further includes a mounting bracket 4. The mounting bracket 4 is used to install the seat belt assembly. The mounting bracket 4 is located on the inner side of the lower end of the B-pillar inner panel 22 and is connected to the sill inner panel 32. The mounting bracket 4, the B-pillar inner panel 22, and the sill inner panel 32 together define a sixth cavity 41, which is located on the upper side of the sill inner panel 22. That is, while the B-pillar inner panel 22 is connected to the sill inner panel 32, it is also connected to the sill inner panel 32 through the mounting bracket 4. At the same time, the mounting bracket 4, the B-pillar inner panel 22, and the sill inner panel 32 together define the sixth cavity 41, which can improve the rigidity of the connection position between the mounting bracket 4 and the B-pillar inner panel 22 and the sill inner panel 32. Therefore, the reliability of the connection between the B-pillar 2 and the sill 3 can be improved. In a specific example, the mounting bracket 4 is used to install the seat belt pretensioner.

[0059] In some embodiments, the vehicle body structure 100 further includes a side outer panel 5, which is disposed on the outside of the A-pillar 1, B-pillar 2 and sill 3 and welded to the A-pillar 1, B-pillar 2 and sill 3. In addition, the B-pillar inner panel reinforcing plate 23 is welded to the B-pillar outer panel 21, the B-pillar inner panel 22, the A-pillar upper outer panel 11 and the A-pillar upper inner panel 12. The B-pillar inner panel 22 is welded to the A-pillar upper inner panel 12, the sill inner panel 32, the sill reinforcing plate 33 and the mounting bracket 4. The sill reinforcing plate 33 is welded to the sill outer panel 31. The sill inner panel reinforcing plate 37 and the mounting bracket 4 are welded to the sill inner panel 32.

[0060] According to some embodiments of this utility model, the A-pillar 1 includes an upper outer panel 11, and the sill 3 includes a sill outer panel 31. The upper outer panel 11, the B-pillar outer panel 21, and the sill outer panel 31 are integrally formed. Therefore, this integrally formed structure not only ensures the structural and performance stability of the upper outer panel 11, the B-pillar outer panel 21, and the sill outer panel 31, but also facilitates molding and simplifies manufacturing. Furthermore, it eliminates the need for assembly parts and connection processes used to connect the upper outer panel 11, the B-pillar outer panel 21, and the sill outer panel 31, reducing the number of weld points between them. This results in lower production costs and significantly improves the assembly efficiency of the upper outer panel 11, the B-pillar outer panel 21, and the sill outer panel 31, ensuring reliable connection. In a specific example, the upper outer panel 11, the B-pillar outer panel 21, and the sill outer panel 31 together constitute an integrally formed thermoformed equal-thickness door ring.

[0063] According to the second aspect embodiment of the present invention, by providing a plurality of first sub-cavities 24 in the B-pillar 2, the rigidity of the B-pillar 2 can be improved to enhance its resistance to deformation during the top pressure process, and the deformation amplitude of the B-pillar 2 after bearing an impact can be reduced, thereby improving the collision performance of the vehicle body structure 100 and enhancing the safety of the vehicle body structure 100.
