[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0033] Please see Figure 1 and Figure 2 This application provides a vehicle body structure 100 that defines a seating space to accommodate passengers or goods. In this embodiment, the vehicle body structure 100 includes a vehicle pillar 10 and a vehicle sill 20, with the vehicle pillar 10 connected to the vehicle sill 20. The vehicle pillar 10 includes an inner pillar plate 11 and an outer pillar plate 12. The inner pillar plate 11 is located on the side of the vehicle sill 20 facing the seating space, and the outer pillar plate 12 is located on the side of the vehicle sill 20 away from the seating space. The inner pillar plate 11 and the outer pillar plate 12 are located on opposite sides of the vehicle sill 20, and are connected to the vehicle sill 20, clamping the vehicle sill 20 to ensure a stable connection between the vehicle pillar 10 and the vehicle sill 20.

[0034] In some embodiments, the vehicle sill 20 is an aluminum alloy structure, while the inner pillar plate 11 and outer pillar plate 12 are steel structures. The inner pillar plate 11 (or outer pillar plate 12) is connected to the vehicle sill 20 using a flow drill screw (FDS) process. The aluminum alloy vehicle sill 20 is lightweight, which can reduce the overall weight of the vehicle body and facilitate the lightweighting of the vehicle body structure 100. In other embodiments, both the vehicle sill 20 and the vehicle pillar 10 are steel structures, in which case the vehicle sill 20 and the vehicle pillar 10 can be connected by welding, resulting in a more stable connection.

[0035] Please see Figure 3 In this embodiment, the vehicle body structure 100 further includes a first connector 30, which is used to enhance the connection stability between the vehicle sill 20 and the pillar outer panel 12. Specifically, the vehicle sill 20 has an internally hollow structure to reduce its weight. The first connector 30 is disposed inside the vehicle sill 20 and is located on the side of the vehicle sill 20 near the pillar outer panel 12. The first connector 30, the vehicle sill 20, and the pillar outer panel 12 are fixedly connected to enhance the connection strength between the vehicle sill 20 and the pillar outer panel 12. In this embodiment, the vehicle body structure 100 also includes bolts (or bolts with nuts). The bolts pass through the first connector 30, the vehicle sill 20, and the pillar outer plate 12 in sequence to fix the three together. The bolt connection provides greater stability, making the connection between the vehicle sill 20 and the pillar outer plate 12 more secure. The first connector 30 can disperse the stress around the bolt holes on the vehicle sill 20 and the pillar outer plate 12, preventing the bolts from directly connecting the vehicle sill 20 and the pillar outer plate 12, thus preventing severe deformation of the vehicle sill 20 and the pillar outer plate 12. It can also prevent local stress concentration and breakage of the bolts. The first connector 30 can improve the structural strength at the connection between the vehicle sill 20 and the pillar outer plate 12. In other embodiments, the vehicle body structure 100 may also include other fasteners besides bolts, such as rivets, pins, etc.

[0036] In this embodiment, the connection process of "using bolts to fix two or more components" is referred to as bolt connection, and will not be described again in the following text.

[0037] Please see Figure 3 and Figure 4In this embodiment, the vehicle body structure 100 further includes a second connecting member 40, which is used to enhance the connection stability between the vehicle sill 20 and the inner pillar panel 11. Specifically, the second connecting member 40 is located between the outer pillar panel 12 and the inner pillar panel 11, and is fixedly connected to both the inner pillar panel 11 and the vehicle sill 20 to strengthen the connection between them. In this embodiment, the second connecting member 40 is bolted to both the vehicle sill 20 and the inner pillar panel 11; other fixing connection methods may be used in other embodiments.

[0038] In summary, this application provides a vehicle body structure 100, which includes a vehicle body pillar 10, a vehicle body sill 20, a first connecting member 30, and a second connecting member 40. The vehicle body pillar 10 includes an outer pillar plate 12 and an inner pillar plate 11, which are located on opposite sides of the vehicle body sill 20 and are connected to the vehicle body sill 20. The vehicle body sill 20 has a hollow internal structure, and the first connecting member 30 is disposed inside the vehicle body sill 20, and the first connecting member 30, the vehicle body sill 20, and the outer pillar plate 12 are fixedly connected. The second connecting member 40 is disposed between the inner pillar plate 11 and the outer pillar plate 12, and is connected to both the inner pillar plate 11 and the vehicle body sill 20.

[0039] In this embodiment, the first connector 30 improves the connection between the vehicle sill 20 and the outer pillar panel 12, making the connection between the outer pillar panel 12 and the vehicle sill 20 more stable; the second connector 40 improves the connection between the vehicle sill 20 and the inner pillar panel 11, making the connection between the inner pillar panel 11 and the vehicle sill 20 more stable; the first connector 30 and the second connector 40 effectively improve the stability of the connection relationship between the vehicle pillar 10 and the vehicle sill 20, improve the structural strength of the vehicle structure 100, and ensure that the vehicle pillar 10 and the vehicle sill 20 can be stably connected when the vehicle structure 100 is subjected to external impact, thereby reducing the probability of tearing between the vehicle sill 20 and the vehicle pillar 10 and ensuring the integrity of the vehicle structure 100.

[0040] Please see Figure 3In this embodiment, the vehicle sill 20 includes a sill body 24 and a reinforcing component 25. The sill body 24 is a cylindrical or hollow tubular structure with surrounding sidewalls defining its internal space. The reinforcing component 25 is disposed within the internal space of the sill body 24 and is connected to the inner wall of the sill body 24. Multiple connection points exist between the reinforcing component 25 and the inner wall of the sill body 24, allowing the reinforcing component 25 to be supported within the internal space of the sill body 24. The reinforcing component 25 improves the structural strength of the sill body 24, resulting in higher impact resistance and making the vehicle sill 20 less prone to deformation or breakage.

[0041] Please see Figure 3 and Figure 5 In this embodiment, the first connector 30 includes a first connecting portion 31 and a second connecting portion 32 connected to each other. The first connecting portion 31 is attached to the side of the sill body 24 near the outer plate 12 of the pillar. The first connecting portion 31 and the outer plate 12 of the pillar are located on opposite sides of this part of the structure of the sill body 24. The first connecting portion 31, the sill body 24, and the outer plate 12 are fixedly connected (e.g., bolted). The attachment of the first connecting portion 31 to the sill body 24 increases the structural strength of the area of ​​the sill body 24 corresponding to the first connecting portion 31, making the fixed connection relationship between the first connecting portion 31, the sill body 24, and the outer plate 12 more stable. The second connecting portion 32 is fixedly connected to the reinforcing component 25 (e.g., bolted). The second connecting portion 32 increases the correlation between the first connector 30 and the vehicle sill 20, making the connection relationship between the first connector 30 and the vehicle sill 20 more stable, and making the connection relationship between the vehicle sill 20 and the outer plate 12 more stable.

[0042] In this embodiment, the reinforcing component 25 includes at least one first reinforcing rib 251. The opposite sides of the first reinforcing rib 251 are respectively connected to the inner wall of the sill body 24 to support the sill body 24. The first reinforcing rib 251 is a sheet-like or plate-like structure to effectively improve the structural strength of the vehicle sill 20. A first connecting portion 31 is located on one side of the first reinforcing rib 251, and a second connecting portion 32 is connected to the side of the first connecting portion 31 near the first reinforcing rib 251. The second connecting portion 32 protrudes relative to the first connecting portion 31 in a direction away from the pillar outer plate 12. The second connecting portion 32 fits against the first reinforcing rib 251 and is fixedly connected to the first reinforcing rib 251 (e.g., bolted connection). In this embodiment, both the first connecting portion 31 and the second connecting portion 32 are plate-like structures to improve the fit between the first connecting member 30 and the vehicle sill 20. The first connecting member 30 is an angle steel structure with high structural strength, which can improve the structural strength of the vehicle sill 20 and also improve the connection stability between the vehicle sill 20 and the pillar outer plate 12. In other embodiments, the structure of the first connector 30 can be specifically configured according to actual needs.

[0043] In this embodiment, the reinforcing component 25 further includes at least one second reinforcing rib 252, which can be a sheet-like structure or a plate-like structure. The second reinforcing rib 252 is intersecting with the first reinforcing rib 251 and integrally formed to achieve high structural strength of the reinforcing component 25. The opposite sides of the second reinforcing rib 252 are respectively connected to the inner wall of the sill body 24. In this embodiment, the reinforcing component 25 includes multiple first reinforcing ribs 251 and multiple second reinforcing ribs 252. The multiple first reinforcing ribs 251 are sequentially and spaced apart inside the sill body 24, and the multiple second reinforcing ribs 252 are sequentially and spaced apart inside the sill body 24. Each second reinforcing rib 252 is intersecting with at least one first reinforcing rib 251 to form a grid-like structure, thereby giving the reinforcing component 25 high structural strength. When the number of both first reinforcing ribs 251 and second reinforcing ribs 252 is large, one side of the second reinforcing rib 252 is connected to the inner wall of the sill body 24, and the other side can be connected to one of the first reinforcing ribs 251.

[0044] Please see Figure 4 and Figure 6 In this embodiment, the vehicle sill 20 includes a first sill portion 21 and a second sill portion 22 connected to each other. Both the first sill portion 21 and the second sill portion 22 have internal spaces. The first sill portion 21 is located between the second sill portion 22 and the outer pillar plate 12. The second sill portion 22 is located on the side of the first sill portion 21 facing the passenger space. A first connector 30 is disposed inside the first sill portion 21, and the first connector 30, the first sill portion 21, and the outer pillar plate 12 are bolted together. The second sill portion 22 is located between the first sill portion 21 and the inner pillar plate 11. The second sill portion 22 protrudes relative to the first sill portion 21 towards the inner pillar plate 11. The second sill portion 22 is connected to the inner pillar plate 11 (e.g., using a flow drill screw connection). A portion of the structure of the first sill portion 21 is spaced apart from the inner pillar plate 11. In this embodiment, the second sill portion 22 is connected to the inner side of the first sill portion 21.

[0045] The first sill portion 21 and the second sill portion 22 are arranged in an L-shape, forming an accommodating space 23 located below the second sill portion 22. A second connecting member 40 is disposed within the accommodating space 23, and the inner pillar plate 11 is located on one side of the accommodating space 23. The second connecting member 40 is positioned between the inner pillar plate 11 and the first sill portion 21, and is fixedly connected to both the first sill portion 21 (e.g., by bolts) and the inner pillar plate 11 (e.g., by bolts), thereby improving the connection strength and stability between the vehicle sill 20 and the inner pillar plate 11. In this embodiment, the structure of the vehicle sill 20 is fully utilized, satisfying the connection between the vehicle sill 20 and the inner pillar plate 11 without increasing the space occupied by the vehicle structure 100. Furthermore, the second connecting member 40 strengthens the connection between the vehicle sill 20 and the inner pillar plate 11.

[0046] Please see Figure 4 , Figure 6 and Figure 7 In this embodiment, an extension 1112 is provided on one side of the inner plate 11 of the column. The extension 1112 is partially spaced from the first threshold portion 21. A second connector 40 is located between the extension 1112 and the first threshold portion 21, and the second connector 40 is fixedly connected to both the extension 1112 and the first threshold portion 21. In this embodiment, the size of the extension 1112 is related to the number of second connectors 40. As an example, if there is only one second connector 40, the size of the extension 1112 can be set to be relatively small, just enough to be fixedly connected to the second connector 40. As another example, if there are two, three or more second connectors 40, the size of the extension 1112 can be set to be relatively large, so that it can be fixedly connected to multiple second connectors 40 simultaneously. In this embodiment, the inner panel 11 of the pillar may include an inner panel body 111. The inner panel body 111 is located on the side of the vehicle sill 20 away from the outer panel 12 of the pillar. The inner panel body 111 includes a main body 1111 and an extension 1112 mentioned above. The extension 1112 is connected to the lower side of the main body 1111 and extends downward relative to the main body 1111 to be spaced apart from the first sill portion 21.

[0047] In this embodiment, the vehicle body pillar 10 can be an A-pillar (located at the windshield), a B-pillar (located between the front and rear doors), a C-pillar (located at the rear windshield), or a D-pillar (located at the rear windshield of vehicles with longer bodies such as SUVs and MPVs). In this embodiment, the A-pillar is used as an example to illustrate the vehicle body pillar 10.

[0048] Please see Figure 4 and Figure 7In this embodiment, the vehicle body structure 100 is provided with a torque box assembly at its forward front end. The torque box assembly includes a torque box base plate 71, which is located around the vehicle body pillar 10. Specifically, the vehicle body sill 20 (and the vehicle body pillar 10) is disposed on one side of the torque box base plate 71, at least a portion of the structure of the vehicle body sill 20 is located above the torque box base plate 71, a second sill portion 22 is disposed opposite to the torque box base plate 71, and a second connecting member 40 is located between the torque box base plate 71 and the second sill portion 22.

[0049] A portion of the torque box base plate 71 is located on the side of the vehicle pillar 10 facing the passenger space. The vehicle structure 100 also includes a third connector 50, located on the side of the pillar inner plate 11 facing away from the vehicle sill 20. The third connector 50 is connected (e.g., by welding, bolting, etc.) to the torque box base plate 71, and the third connector 50 can improve the performance of the torque box assembly. Please refer to [link to relevant documentation]. Figure 8 In this embodiment, the torque box assembly also includes a torque box sealing plate 72, which is generally positioned above the third connector 50. The opposite sides of the third connector 50 are connected to the torque box bottom plate 71 and the torque box sealing plate 72, respectively.

[0050] The third connector 50 and the second connector 40 are located on opposite sides of the extension 1112. The second connector 40, the extension 1112, and the third connector 50 are fixedly connected (e.g., by bolts) so that the overall structure formed by the vehicle pillar 10 and the vehicle sill 20 (hereinafter referred to as the overall door frame structure) establishes a connection relationship with more vehicle structures, thereby giving the overall door frame structure high strength and structural stability. In this embodiment, the vehicle body structure 100 may include a floor 80. The third connector 50, the torque box base plate 71, and the floor 80 can be fixedly connected (e.g., by welding or bolts), making the position of the torque box assembly more stable. This allows the torque box assembly to effectively improve the structural strength of the overall door frame structure, making the overall door frame structure less prone to disintegration or tearing.

[0051] Please see Figure 7 and Figure 8In this embodiment, the third connector 50 includes a support portion 51 and an overlapping portion 52. One side of the support portion 51 is connected to the torsion box bottom plate 71, and the other side of the support portion 51 is connected to the torsion box sealing plate 72. The support portion 51 has a sheet-like structure, with multiple protrusions formed on one side surface. When viewed from the other side of the support portion 51, multiple grooves are formed at the locations of the multiple protrusions. Therefore, the support portion 51 has an uneven structure with obvious protrusions or grooves, which makes the structure of the support portion 51 more rigid and less prone to deformation, thereby improving the performance of the torsion box assembly. The overlapping portion 52 is connected to the side of the support portion 51 near the extension portion 1112. The overlapping portion 52 and the second connector 40 are located on opposite sides of the extension portion 1112, respectively. The overlapping portion 52, the extension portion 1112, and the second connector 40 are fixedly connected (e.g., bolted). In this embodiment, the overlapping portion 52 is a flat, sheet-like structure. The overlapping portion 52 extends relative to the extension portion 1112 towards the torsion box bottom plate 71, causing the third connector 50 to have a bent structure, thus increasing the structural strength of the third connector 50. The overlapping portion 52 corresponds to the extension portion 1112, and the overlapping portion 52 fits snugly against the extension portion 1112, resulting in a relatively stable connection between the overlapping portion 52 and the extension portion 1112.

[0052] Please see Figure 7 and Figure 9 In this embodiment, the second connector 40 includes a first bent portion 41, a connecting portion 45, and a second bent portion 42. The first bent portion 41 and the second bent portion 42 are respectively connected to opposite sides of the connecting portion 45. The first bent portion 41 bends relative to the connecting portion 45, and the second bent portion 42 bends relative to the connecting portion 45. The bending directions of the first bent portion 41 and the second bent portion 42 relative to the connecting portion 45 are the same, and the first bent portion 41 and the second bent portion 42 are arranged at intervals. The first threshold portion 21, the first bent portion 41, the second bent portion 42, the extension portion 1112, and the third connector 50 are arranged sequentially. The first bent portion 41 is attached to and fixedly connected to the first threshold portion 21 (e.g., bolted connection). The second bent portion 42, the extension portion 1112, and the third connector 50 (the overlapping portion 52) are attached to and fixedly connected sequentially. In some embodiments, the connecting portion 45 is fixedly connected to the torsion box bottom plate 71 (e.g., bolted connection or welding). In this embodiment, the second connector 40 is a folded sheet structure, which is lightweight and has little impact on the weight of the vehicle body structure 100. In other embodiments, the structure of the second connector 40 can be specifically configured according to requirements, for example, it can be a solid block or columnar structure.

[0053] Please see Figure 10In this embodiment, the inner pillar panel 11 includes an inner panel body 111 and a folded edge portion 112. The folded edge portion 112 is connected to one side of the inner panel body 111 and is located approximately in front of the inner panel body 111 in the forward direction of the vehicle body structure 100. The folded edge portion 112 is bent relative to the inner panel body 111 and extends relative to the inner panel body 111 towards the outer pillar panel 12. The main body portion 1111 and the extension portion 1112 are respectively connected to the side of the folded edge portion 112 away from the outer pillar panel 12. The main body portion 1111 and the extension portion 1112 are arranged side by side and connected to each other.

[0054] The folded edge 112 is in a state of covering the end of the vehicle body sill 20, for example... Figure 2 The folded edge 112 can cover part of the structure of the second sill portion 22, or cover part of the structure of both the second sill portion 22 and the first sill portion 21. The folded edge 112 is located on one side of the accommodating space 23 in the forward direction of the vehicle body structure 100. The part of the structure of the folded edge 112 corresponding to the accommodating space 23 is located between the inner panel body 111 and the first sill portion 21. The structure of the folded edge 112 is located on one side of the second connector 40. The second connector 40 is fixedly connected to the folded edge 112 (e.g., bolted connection), increasing the number of connection points between the second connector 40 and the inner panel 11 of the pillar, and improving the stability of the connection relationship between the second connector 40 and the inner panel 11 of the pillar, and between the inner panel 11 of the pillar and the vehicle sill 20.

[0055] Please see Figure 10 In this embodiment, the torque box base plate 71 includes a base plate body 711 and a protrusion 712. The base plate body 711 is generally plate-shaped and relatively flat. The vehicle sill 20 is located above the base plate body 711. The base plate body 711 and the second sill portion 22 are spaced apart from each other. The second connecting member 40 is located between the base plate body 711 and the second sill portion 22. The protrusion 712 is connected to the base plate body 711. The structure of the protrusion 712 is relatively three-dimensional. The protrusion 712 extends relative to the base plate body 711 towards the direction close to the second sill portion 22. Part of the structure of the protrusion 712 extends into the accommodating space 23. The protrusion 712 is located on the side of the second connecting member 40 away from the folded edge portion 112. The second connecting member 40 is fixedly connected to the protrusion 712 (e.g., bolted connection). In this embodiment, the second connector 40 is fixedly connected to the first threshold 21, the folded edge 112, the extension 1112 of the door panel body, the protrusion 712, and the third connector 50 on all four sides. The overall structure of the door frame is highly connected to other vehicle structures, and the overall structure of the door frame is relatively stable.

[0056] Please see Figure 9 and Figure 10In this embodiment, the second connector 40 further includes a third bend 43 and a fourth bend 44. The first bend 41, the third bend 43, the second bend 42, and the fourth bend 44 are sequentially connected to the outer periphery of the connecting portion 45. The first bend 41, the third bend 43, the second bend 42, and the fourth bend 44 are all bent relative to the connecting portion 45, and the bending directions are the same. The first bend 41 and the second bend 42 are arranged at intervals relative to each other, and the third bend 43 and the fourth bend 44 are both located between the first bend 41 and the second bend 42, and are arranged at intervals relative to each other. The third bend 43 is fixedly connected to the folded edge 112 (e.g., bolted connection), the fourth bend 44 is fixedly connected to the protrusion 712 (e.g., bolted connection), the second bend 42, the inner panel body 111 (the extension 1112), and the third connector 50 (the overlapping portion 52) are fixedly connected, and the first bend 41 is fixedly connected to the first sill portion 21. In this embodiment, the first bend 41, the second bend 42, the third bend 43, the fourth bend 44, and the connecting portion 45 are integrally formed. The bending process makes the second connector 40 three-dimensional, the structure of the second connector 40 is stable and has high strength, and the weight of the second connector 40 is light, with little impact on the overall weight of the vehicle body structure 100. In some embodiments, two adjacent bends can be connected to each other to improve the structural strength of the second connector 40.

[0057] Please see Figure 11 In this embodiment, the vehicle body structure 100 further includes a fourth connecting member 60, which is disposed between the inner pillar plate 11 and the outer pillar plate 12. The fourth connecting member 60 and the second connecting member 40 are located on opposite sides of the vehicle sill 20, respectively. The second connecting member 40 is approximately located below the vehicle sill 20, and the fourth connecting member 60 is approximately located on the top side of the vehicle sill 20. The fourth connecting member 60 is connected to the vehicle sill 20. The fourth connecting member 60 is a steel structure, and the vehicle sill 20 is an aluminum alloy structure. The fourth connecting member 60 and the vehicle sill 20 can be connected by a flow drill screw process or by a bolt connection. In this embodiment, the fourth connecting member 60 is fixedly connected to the inner pillar plate 11 (e.g., by bolt connection). The fourth connecting member 60 fixes the top side structure of the vehicle sill 20 to the inner pillar plate 11, and the second connecting member 40 fixes the bottom side structure of the vehicle sill 20 to the inner pillar plate 11 and other vehicle structures, thereby improving the connection strength between the vehicle sill 20 and the inner pillar plate 11 and making the overall door frame structure more stable.

[0058] Please see Figure 6 In this embodiment, the fourth connector 60 is connected to the second threshold portion 22 near the inner plate 11 (the inner plate body 111) of the column, and the fourth connector 60 and the second connector 40 are located on opposite sides of the second threshold portion 22. Please refer to [link / reference]. Figure 11 and Figure 12 The fourth connector 60 is a hollow tubular structure. It is connected to the top side of the second sill portion 22 and is fixedly connected to the inner pillar plate 11. In this embodiment, the second connector 40 fixes the first sill portion 21 to the inner pillar plate 11, and the fourth connector 60 fixes the second sill portion 22 to the inner pillar plate 11, making the connection between the vehicle sill 20 and the inner pillar plate 11 more stable. In other embodiments, the structure of the fourth connector 60 can be configured according to requirements.

[0059] Please see Figure 11 and Figure 13 In this embodiment, the vehicle body pillar 10 is an A-pillar located at the front end of the vehicle body structure 100. A front bulkhead 90 is also provided at the front end of the vehicle body structure 100. The front bulkhead 90 is arranged parallel to the vehicle body pillar 10, and the arrangement direction of the front bulkhead 90 and the vehicle body pillar 10 approximately intersects the forward direction of the vehicle body structure 100. The front bulkhead 90 is located on the side of the inner pillar panel 11 facing away from the outer pillar panel 12. Part of the structure of the front bulkhead 90 is attached to the outer pillar panel 12. The front bulkhead 90 and the fourth connecting member 60 are located on opposite sides of the outer pillar panel 12. The front bulkhead 90, the inner pillar panel 11, and the fourth connecting member 60 are fixedly connected (e.g., bolted) to allow the overall door frame structure to be associated with more vehicle structures, thereby improving the structural strength and stability of the overall door frame structure.

[0060] In this embodiment, the front panel 90 includes an integrally formed panel body 91 and a fitting portion 92. The panel body 91 is generally a sheet or plate structure. The fitting portion 92 is connected to the side of the panel body 91 near the inner plate 11 of the column. The fitting portion 92 is bent relative to the panel body 91 and fits against the surface of the inner plate 11 of the column. The fourth connector 60, the inner plate 11 of the column, and the fitting portion 92 are bolted together.

[0061] In summary, the vehicle body structure 100 in this embodiment includes an overall door frame structure and a first connecting member 30, a second connecting member 40, a third connecting member 50, and a fourth connecting member 60. The first connecting member 30 makes the connection between the vehicle sill 20 and the outer panel 12 of the pillar more stable. The second connecting member 40 and the fourth connecting member 60 make the connection between the vehicle sill 20 and the inner panel 11 of the pillar more stable. Under the combined action of the second connecting member 40, the third connecting member 50, and the fourth connecting member 60, the overall door frame structure is associated with multiple vehicle structures, giving the overall door frame structure high structural strength and stability. This makes it less likely for the vehicle sill 20 and the vehicle pillar 10 to separate or tear under external impact, thereby reducing the damage to the vehicle body structure 100 and the user in an accident. The associated vehicle structures include, but are not limited to: the torque box bottom plate 71, the torque box sealing plate 72, the front bulkhead 90, and the floor 80.

[0062] Please see Figure 14 This application embodiment also provides a vehicle 1000, which includes the body structure 100 mentioned above. In this embodiment, the vehicle 1000 may further include a cover 900, which is a part that covers the outer periphery of the body structure 100 to form the exterior surface of the vehicle.
