Description

Technical Field

[0001] This application relates to the field of vehicle body structure technology, and in particular to a door sill pillar reinforcement assembly, vehicle body structure and vehicle. Background Technology

[0002] Currently, the conventional approach to improve the strength of the front end of the door sill is to reinforce the entire door sill or the hinge pillar (lower section of the A-pillar). However, the above approach cannot solve the problem of cracking of the inner and outer panels of the door sill. When the vehicle is impacted, the door sill or pillar will bend and deform, compressing the effective space inside the vehicle and thus reducing the survival space for occupants. Summary of the Invention

[0003] This application provides a door sill pillar reinforcement assembly, a vehicle body structure, and a vehicle, aiming to improve the problem of cracking in the inner and outer door sill panels, which leads to a reduction in the occupant survival space.

[0004] This application provides a door sill pillar reinforcement assembly, including a pillar, a door sill, and a reinforcement structure. The pillar is connected to the door sill, and the reinforcement structure is disposed between the door sill and the wheel along the vehicle's longitudinal direction. The reinforcement structure is fixedly connected to the front side of the pillar. By fixing the reinforcement structure to the front side of the pillar, the overall rigidity and impact resistance of the pillar can be improved. Simultaneously, by utilizing the space between the door sill and the wheel and placing the reinforcement structure in this space, the wheel can be effectively limited during a collision, thereby controlling the wheel's posture during the collision with the door sill. This avoids the wheel excessively deflecting inwards and directly impacting critical areas such as the base of the pillar or the front end of the door sill, and also reduces the impact of the wheel on the pillar and the front end of the door sill. This effectively improves the problem of separation of the inner and outer panels caused by weld failure, which leads to bending and deformation of the door sill and pillar, reducing passenger compartment deformation and ensuring occupant survival space.

[0005] Optionally, the reinforcing structure includes an inner reinforcing plate and an outer reinforcing plate, the inner reinforcing plate and the outer reinforcing plate are connected, and a first cavity is formed between them; The inner reinforcing plate is positioned between the outer reinforcing plate and the pillar along the vehicle's longitudinal direction, forming a second cavity between the inner reinforcing plate and the pillar. Through the first and second cavities, slight compression and deformation can absorb some energy, reducing the impact force transmitted to the pillar and sill.

[0006] Optionally, the inner reinforcing plate includes an inner main plate, a first overlapping plate, and a second overlapping plate, wherein the inner main plate is connected between the first overlapping plate and the second overlapping plate; The outer reinforcing plate includes an outer main plate, a third overlapping plate, and a fourth overlapping plate, with the outer main plate connected between the third overlapping plate and the fourth overlapping plate; The first overlapping plate is connected to the third overlapping plate, and the second overlapping plate is connected to the fourth overlapping plate. The first cavity is formed between the inner main body plate and the outer main body plate, with the inner main body plate separating the first cavity and the second cavity. Through the double overlapping of the inner and outer sides, the inner and outer sides of the reinforcing structure can be sealed, thus making the first cavity an independent enclosed space that can efficiently absorb collision energy through its own deformation. Furthermore, the connection between the inner and outer sides of the reinforcing structure forms a stable connection structure, enhancing the overall structural strength.

[0007] Optionally, the inner main body plate is provided with a plurality of first protrusions, which are disposed in the first cavity and connected to the outer main body plate, thereby enhancing the connection strength between the inner reinforcing plate and the outer reinforcing plate and improving the structural rigidity of the entire reinforcing structure.

[0008] Optionally, the outer main body plate is provided with a plurality of second protrusions, the plurality of second protrusions being disposed in the first cavity and connected to the inner main body plate; or, The outer main body plate is provided with a plurality of second protrusions, which are disposed in the first cavity, and each first protrusion is connected to a corresponding second protrusion. By connecting the second protrusion to the inner main body plate or connecting the second protrusion to the first protrusion, the connection strength between the inner and outer reinforcing plates can be enhanced, thereby improving the structural rigidity of the entire reinforced structure.

[0009] Optionally, the inner reinforcing plate is provided with a plurality of first connecting holes, and the outer reinforcing plate is provided with a plurality of second connecting holes. Each first connecting hole communicates with the corresponding second connecting hole. The first connecting hole and the second connecting hole are used to pass through a first fastener so that the inner side of the reinforcing structure is connected to the column, thereby enabling the inner side of the reinforcing structure to be assembled on the column.

[0010] Optionally, the inner reinforcing plate is provided with a plurality of third connecting holes, which are used to insert second fasteners so that the outer side of the reinforcing structure is connected to the column, thereby enabling the assembly of the outer side of the reinforcing structure with the column.

[0011] Optionally, the outer reinforcing plate is provided with multiple through holes, and each of the third connecting holes can be exposed from the corresponding through hole. The projection of the third connecting hole on the front side of the column is located inside the projection of the through hole on the front side of the column. By using the through holes to avoid obstruction, the operating tool can pass through the through holes to reach the third connecting hole and directly act on the second fastener, facilitating the operation of the second fastener in the third connecting hole.

[0012] Optionally, the column includes an inner column plate and an outer column plate. The outer column plate is connected to the outside of the inner column plate. The inner side of the reinforcing structure is connected to the inner column plate, and the outer side of the reinforcing structure is connected to the outer column plate. By forming a stable structure with the inner and outer column plates through mutual restraint, the connection strength and impact resistance between the inner and outer column plates are improved, and the risk of weld cracking between the inner and outer column plates is reduced.

[0013] Optionally, the sill post reinforcement assembly further includes a front crossbeam and a torsion box. The front crossbeam and the torsion box are connected to the inner plate of the post, and the inner side of the reinforcement structure is connected to the front crossbeam and the torsion box. The front crossbeam and the torsion box are connected to the inner plate of the post, thereby achieving an indirect connection between the inner side of the reinforcement structure and the inner plate of the post.

[0014] Optionally, the torque box is disposed below the front crossbeam, and the upper part of the torque box is connected to the lower part of the front crossbeam. The connection between the torque box and the front crossbeam allows for load sharing, preventing force concentration on a single component or connection point.

[0015] Optionally, the threshold includes an inner threshold panel and an outer threshold panel. The outer threshold panel is connected to the outside of the inner threshold panel and is connected to the outer panel of the post. The inner threshold panel is connected to the inner panel of the post. This double-fixing of the threshold, both inside and outside, reduces loosening of the connection and jointly constrains the relative displacement between the threshold and the post, preventing breakage due to concentrated load when connected on one side.

[0016] This application also provides a vehicle body structure, including the door sill pillar reinforcement assembly as described in any of the preceding claims.

[0017] In the vehicle body structure of this embodiment, the door sill pillar reinforcement assembly can improve the problem of bending deformation of door sills and pillars, thereby increasing the strength of the vehicle body structure, reducing passenger compartment deformation, and ensuring passenger survival space.

[0018] This application also provides a vehicle including the body structure described above.

[0019] In this embodiment, the vehicle's door sill and pillar reinforcement assembly improves the bending and deformation problems of the door sill and pillars, thereby enhancing the strength of the vehicle body structure, reducing deformation of the passenger compartment, and ensuring the survival space for occupants.

[0022] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] The front of the door sill is a "composite load-bearing area" on the side of the vehicle, needing to withstand longitudinal, lateral, and vertical forces during vehicle movement (bumps, braking) and collisions. To improve the strength of the front of the door sill, the entire door sill or the hinge pillar (lower section of the A-pillar) is usually reinforced. However, the above methods cannot solve the problem of separation of the inner and outer panels due to weld failure, which leads to bending and deformation of the door sill and A-pillar. This deformation directly intrudes into the passenger compartment, causing excessive deformation of the passenger compartment and affecting survival space. Furthermore, reinforcing the door sill or pillar results in unreasonable material utilization and redundant vehicle weight. The additional structure affects the overall vehicle lightweighting level and is not conducive to energy consumption optimization and handling stability improvement.

[0024] like Figures 1 to 6 As shown in the figure, a door sill reinforcement assembly 100 provided in this application embodiment includes a door sill 1, a door sill 2 and a reinforcement structure 3. The door sill 1 is connected to the door sill 2, and the reinforcement structure 3 is disposed between the door sill 2 and the wheel along the front-rear direction of the vehicle. The reinforcement structure 3 is fixedly connected to the front side of the door sill 1.

[0025] In this embodiment, the reinforcing structure 3 is fixedly connected to the front side of the pillar 1, which can improve the overall rigidity and impact resistance of the pillar 1, providing a more stable support foundation for the side of the vehicle body. At the same time, without affecting the shape of the sill 2, the space between the sill 2 and the wheel is cleverly utilized. By placing the reinforcing structure 3 in the space between the sill 2 and the wheel, it can effectively limit the wheel during a collision, thereby controlling the posture of the wheel when colliding with the sill 2. This can prevent the wheel from deflecting too far inward and directly hitting the root of the pillar 1 or the front end of the sill 2, and can also reduce the impact of the wheel on the front end of the pillar 1 and the sill 2. This can effectively improve the problem of separation of the inner and outer panels of the pillar 1 due to weld failure, which leads to bending and deformation of the sill 2 and the pillar 1, reducing the deformation of the passenger compartment and ensuring the survival space of the occupants.

[0026] As an example, the door sill pillar reinforcement assembly 100 includes a pillar 1, a door sill 2, and a reinforcement structure 3. The pillar 1 is an A-pillar, and its lower end is connected to the front end of the door sill 2. The reinforcement structure 3 is positioned between the door sill 2 and the wheel along the vehicle's longitudinal direction, and is fixedly connected to the front side of the pillar 1. That is, in the vehicle's longitudinal direction, the reinforcement structure 3, the lower end of the pillar 1, and the door sill 2 are arranged sequentially. The reinforcement structure 3 does not occupy interior space of the vehicle body, yet it can support the pillar 1 and the door sill 2, and directly increase the rigidity of the pillar 1.

[0027] In small offset collisions (such as 25% offset collisions), when a collision occurs, the reinforcing structure 3 located between the sill 2 and the wheel can directly contact the wheel. Its rigidity prevents the wheel from excessively shifting inwards towards the vehicle body, thereby controlling the wheel's rotation angle in the small offset collision. This avoids the wheel tilting and directly impacting critical areas such as the base of the pillar 1 or the front end of the sill 2, reducing direct impact damage to the sill 2 at the source of the collision. Simultaneously, the reinforcing structure 3 can offset some of the impact force, reducing the load on the weld points of the pillar 1 and sill 2, and reducing deformation of the pillar 1 and sill 2 due to structural failure.

[0028] In one embodiment, such as Figure 1 As shown, the reinforcing structure 3 includes an inner reinforcing plate 31 and an outer reinforcing plate 32. The inner reinforcing plate 31 and the outer reinforcing plate 32 are connected and a first cavity is formed between them. The inner reinforcing plate 31 is disposed between the outer reinforcing plate 32 and the pillar 1 along the front-rear direction of the vehicle, and a second cavity is formed between the inner reinforcing plate 31 and the pillar 1.

[0029] A composite reinforcement structure can be formed by connecting the inner reinforcement plate 31 and the outer reinforcement plate 32. When the reinforcement structure 3 is installed on the column 1, the reinforcement structure 3 will first come into contact with the wheel when a collision occurs. The first cavity between the inner reinforcement plate 31 and the outer reinforcement plate 32 and the second cavity between the inner reinforcement plate 31 and the column 1 can absorb some energy through slight compression and deformation, thereby reducing the impact force transmitted to the column 1 and the sill 2.

[0030] As an example, the reinforcing structure 3 includes an inner reinforcing plate 31 and an outer reinforcing plate 32. The outer reinforcing plate 32 is connected to the outside of the inner reinforcing plate 31, and the inner reinforcing plate 31 is disposed between the outer reinforcing plate 32 and the front side of the column 1. The inner reinforcing plate 31 can separate and form a first cavity and a second cavity. During installation, the inner reinforcing plate 31 and the outer reinforcing plate 32 can be connected as a whole by welding, screwing, or other methods before the reinforcing structure 3 is assembled onto the column 1. The reinforcing structure 3 and the column 1 can be connected by welding, screwing, or other methods.

[0031] Preferably, the inner reinforcing plate 31 and the outer reinforcing plate 32 are welded together and then connected to the column 1 by bolts.

[0032] The inner reinforcing plate 31 is arranged along the length of the column 1, and the outer reinforcing plate 32 is also arranged along the length of the column 1. The lower ends of the inner reinforcing plate 31 and the outer reinforcing plate 32 can be aligned with the lower end of the sill 2. After the inner reinforcing plate 31 and the outer reinforcing plate 32 are welded together, they can form a structure that wraps around the front end of the column 1 and the sill 2. During a collision, the area and angle in direct contact with the tire will change significantly. In a frontal offset collision, this not only improves the impact resistance of the front end of the sill 2 against the tire and other chassis components and reduces the force on the column 1 and the sill 2, but also controls the rotation angle of the wheel during the collision, reducing the impact of the tire on the sill 2.

[0033] By adjusting the thickness, material, and shape of the inner reinforcing plate 31 and the outer reinforcing plate 32, vehicles of different weights can be matched to achieve similar functions with minimal weight.

[0034] In one embodiment, such as Figure 5 , Figure 6 As shown, the inner reinforcing plate 31 includes an inner main plate 311, a first overlapping plate 312 and a second overlapping plate 313, with the inner main plate 311 connected between the first overlapping plate 312 and the second overlapping plate 313; the outer reinforcing plate 32 includes an outer main plate 321, a third overlapping plate 322 and a fourth overlapping plate 323, with the outer main plate 321 connected between the third overlapping plate 322 and the fourth overlapping plate 323.

[0035] The first overlapping plate 312 is connected to the third overlapping plate 322, the second overlapping plate 313 is connected to the fourth overlapping plate 323, the first cavity is formed between the inner main plate 311 and the outer main plate 321, and the inner main plate 311 separates the first cavity and the second cavity.

[0036] In this embodiment, the first overlapping plate 312 is connected to the third overlapping plate 322, and the second overlapping plate 313 is connected to the fourth overlapping plate 323. Through the double overlapping of the inner and outer sides, the inner and outer sides of the reinforcing structure 3 can be sealed, thereby making the first cavity an independent closed space. The closed cavity can efficiently absorb collision energy through its own deformation. Moreover, the reinforcing structure 3 can form a stable connection structure through the connection of the inner and outer sides, thereby enhancing the overall structural strength.

[0037] As an example, the inner reinforcing plate 31 includes an inner main plate 311, a first overlapping plate 312 and a second overlapping plate 313. The inner main plate 311 is connected between the first overlapping plate 312 and the second overlapping plate 313. The first overlapping plate 312 is connected to the inner side of the inner main plate 311, and the second overlapping plate 313 is connected to the outer side of the inner main plate 311.

[0038] The outer reinforcing plate 32 includes an outer main plate 321, a third overlapping plate 322 and a fourth overlapping plate 323. The outer main plate 321 is connected between the third overlapping plate 322 and the fourth overlapping plate 323. The third overlapping plate 322 is connected to the inner side of the outer main plate 321 and the fourth overlapping plate 323 is connected to the outer side of the outer main plate 321.

[0039] During assembly, the outer reinforcing plate 32 and the inner reinforcing plate 31 are placed opposite each other, the first overlapping plate 312 and the third overlapping plate 322 are welded together, and the second overlapping plate 313 and the fourth overlapping plate 323 are welded together to obtain the reinforcing structure 3.

[0040] In one embodiment, such as Figure 5 As shown, the inner main body plate 311 is provided with a plurality of first protrusions 314, which are disposed in the first cavity and connected to the outer main body plate 321. The connection between the first protrusions 314 and the outer main body plate 321 can further enhance the connection strength between the inner reinforcing plate 31 and the outer reinforcing plate 32, thereby improving the overall strength of the reinforcing structure 3.

[0041] As an example, the inner main plate 311 is provided with a plurality of first protrusions 314, which protrude toward the outer reinforcing plate 32. The first protrusions 314 are disposed in the first cavity. After the plurality of first protrusions 314 are welded to the outer main plate 321, it is equivalent to constructing a plurality of support structures in the first cavity. These support structures can increase the contact area between the inner reinforcing plate 31 and the outer reinforcing plate 32, enhance the surface strength, and improve the structural strength of the entire reinforcing structure 3.

[0042] Multiple first protrusions 314 are spaced apart along the vertical direction of the vehicle and are located within a first cavity. The first cavity comprises two parts: one part is the cavity between the inner main body plate 311 and the front side of the pillar 1; the other part is the cavity enclosed by the first protrusions 314 as they arch towards the outer reinforcing plate 32. These two parts constitute the complete spatial structure of the first cavity. In this example, the first protrusion 314 is frustum-shaped.

[0043] In one embodiment, such as Figure 5 The diagram shows a schematic representation of the inner reinforcing plate 31. The inner main plate 311 includes a first plate 3111, a second plate 3112, and a third plate 3113. The second plate 3112 is located between the first plate 3111 and the third plate 3113. The first plate 3111 connects to one side of the first overlapping plate 312 and the second plate 3112, and the third plate 3113 connects to the other side of the second overlapping plate 313 and the second plate 3112. The first plate 3111, the second plate 3112, and the third plate 3113 are connected to form a U-shaped structure, with the opening of the U-shaped structure facing the column 1. This allows the first plate 3111, the second plate 3112, the third plate 3113, and the front side of the column 1 to jointly define a second cavity. Multiple first protrusions 314 are provided on the second plate 3112.

[0044] In one embodiment, such as Figure 6 As shown, the outer main body plate 321 is provided with a plurality of second protrusions 325, which are disposed in the first cavity and connected to the inner main body plate 311; or, the outer main body plate 321 is provided with a plurality of second protrusions 325, which are disposed in the first cavity, and each first protrusion 314 is connected to the corresponding second protrusion 325.

[0045] As an example, the outer main body plate 321 is provided with a plurality of second protrusions 325, which are disposed in the first cavity and connected to the inner main body plate 311. The connection between the second protrusions 325 and the inner main body plate 311 can further enhance the connection strength between the inner reinforcing plate 31 and the outer reinforcing plate 32, thereby improving the overall strength of the reinforcing structure 3.

[0046] The second protrusion 325 protrudes towards the inner reinforcing plate 31, and multiple second protrusions 325 are spaced apart along the vertical direction of the vehicle, located within the first cavity. After the multiple second protrusions 325 are welded to the inner main plate 311, they effectively construct multiple support structures within the first cavity. These support structures increase the contact area between the inner reinforcing plate 31 and the outer reinforcing plate 32, enhancing surface strength and improving the overall structural strength of the reinforcing structure 3. In this example, the second protrusion 325 is frustum-shaped.

[0047] As an example, the outer main body plate 321 is provided with a plurality of second protrusions 325, which are disposed in the first cavity. Each first protrusion 314 is connected to the corresponding second protrusion 325. The first protrusions 314 and the second protrusions 325 together constitute the support structure in the first cavity, which can further increase the connection strength between the inner reinforcing plate 31 and the outer reinforcing plate 32.

[0048] The first protrusion 314 protrudes towards the outer reinforcing plate 32, and the second protrusion 325 protrudes towards the inner reinforcing plate 31. The first protrusion 314 can abut against the corresponding second protrusion 325, and the first protrusion 314 and the second protrusion 325 are connected by welding.

[0049] In one embodiment, such as Figure 6 The diagram shows the structure of the outer reinforcing plate 32. The outer main plate 321 includes a fourth plate 3211, a fifth plate 3212, and a sixth plate 3213. The fifth plate 3212 is disposed between the fourth plate 3211 and the sixth plate 3213. The fourth plate 3211 is connected between the third overlapping plate 322 and one side of the fifth plate 3212, and the sixth plate 3213 is connected between the fourth overlapping plate 323 and the other side of the fifth plate 3212. By connecting the fourth plate 3211, the fifth plate 3212, and the sixth plate 3213, a U-shaped outer main plate 321 is obtained, and the opening of the U-shaped structure faces the inner reinforcing plate 31. The inner main plate 311 and the outer main plate 321 define a first cavity.

[0050] The projected area of ​​the outer main plate 321 on the front side of the column 1 is larger than the projected area of ​​the inner main plate 311 on the front side of the column 1. When the inner reinforcing plate 31 and the outer reinforcing plate 32 are assembled, the outer main plate 321 can cover the inner main plate 311, thereby forming a first cavity between the two.

[0051] In one embodiment, such as Figure 5As shown, the inner reinforcing plate 31 is provided with multiple first connecting holes 3121, and the outer reinforcing plate 32 is provided with multiple second connecting holes 3221. Each first connecting hole 3121 communicates with the corresponding second connecting hole 3221. The first connecting holes 3121 and the second connecting holes 3221 are used to pass through first fasteners so that the inner side of the reinforcing structure 3 is connected to the column 1. After the inner reinforcing plate 31 and the outer reinforcing plate 32 are welded together, the first connecting holes 3121 and the second connecting holes 3221 can be aligned. By passing the first fasteners through the second connecting holes 3221 and the first connecting holes 3121 in sequence, the inner side of the reinforcing structure 3 can be assembled on the column 1.

[0052] The first fastener is a screw or bolt, which is used to install and remove the reinforcing structure 3, making it convenient to replace the reinforcing structure 3.

[0053] As an example, the inner reinforcing plate 31 is provided with a plurality of first connecting holes 3121, which are spaced apart on the first overlapping plate 312. The outer reinforcing plate 32 is provided with a plurality of second connecting holes 3221, which are spaced apart on the third overlapping plate 322. After the first connecting holes 3121 and the second connecting holes 3221 are aligned one by one, the first overlapping plate 312 and the third overlapping plate 322 are welded together.

[0054] In one embodiment, such as Figure 5 As shown, the inner reinforcing plate 31 is provided with multiple third connecting holes 3131, which are used to pass through second fasteners to connect the outer side of the reinforcing structure 3 to the column 1. After the second fastener passes through the third connecting holes 3131, the outer side of the reinforcing structure 3 can be assembled with the column 1.

[0055] When the reinforcing structure 3 is connected to the column 1, the reinforcing structure 3 can be installed on the column 1 through the first fasteners inserted in the first connecting hole 3121 and the second connecting hole 3221, and the second fasteners in the third connecting hole 3131.

[0056] The second fastener is a screw or bolt, which is used to install and remove the reinforcing structure 3, making it convenient to replace the reinforcing structure 3.

[0057] In one embodiment, such as Figure 2 , Figure 6As shown, the outer reinforcing plate 32 is provided with multiple through holes 324, and each third connecting hole 3131 can be exposed from the corresponding through hole 324. The projection of the third connecting hole 3131 on the front side of the column 1 is located inside the projection of the through hole 324 on the front side of the column 1. The through holes 324 can be bypassed, allowing the operating tool to pass through the through hole 324 to reach the third connecting hole 3131 and directly act on the second fastener, facilitating the operation of the second fastener in the third connecting hole 3131.

[0058] The number of through holes 324 is the same as the number of third connecting holes 3131, and the positions of through holes 324 and third connecting holes 3131 correspond to each other in the front-rear direction of the vehicle.

[0059] As an example, the inner reinforcing plate 31 is provided with a plurality of third connecting holes 3131, which are spaced apart on the second overlapping plate 313 of the inner reinforcing plate 31. The outer reinforcing plate 32 is provided with a plurality of through holes 324, which are spaced apart on the outer main plate 321. The positions of the through holes 324 and the third connecting holes 3131 are correspondingly arranged in the front-rear direction of the vehicle. The second fastener in the corresponding third connecting hole 3131 can be installed or removed through each through hole 324.

[0060] In one embodiment, such as Figure 3 , Figure 4 As shown, the column 1 includes an inner column plate 11 and an outer column plate 12. The outer column plate 12 is connected to the outer side of the inner column plate 11. The inner side of the reinforcing structure 3 is connected to the inner column plate 11, and the outer side of the reinforcing structure 3 is connected to the outer column plate 12. By connecting the inner column plate 11 and the outer column plate 12 to the inner and outer sides of the reinforcing structure 3 respectively, the reinforcing structure 3 is no longer an independent attachment to the column 1, but forms a stable structure with the inner column plate 11 and the outer column plate 12, thereby improving the connection strength and impact resistance between the inner column plate 11 and the outer column plate 12, reducing the risk of weld cracking between the inner column plate 11 and the outer column plate 12, ensuring the integrity of the crew compartment, and guaranteeing the crew survival space.

[0061] In one embodiment, the front side of the column 1 is provided with a plurality of fourth connecting holes, which are located on the front side of the outer plate 12 of the column. The inner reinforcing plate 31 is provided with a plurality of third connecting holes 3131, which are spaced apart on the second overlapping plate 313 of the inner reinforcing plate 31. The number of third connecting holes 3131 is the same as the number of fourth connecting holes, and the third connecting holes 3131 correspond to the fourth connecting holes. When connecting the reinforcing structure 3, a third fastener is inserted through the third connecting hole 3131 and the corresponding fourth connecting hole, which can connect the outer side of the reinforcing structure 3 to the front side of the column 1. The third fastener can be a screw or bolt, etc.

[0062] In one embodiment, such as Figure 1 , Figure 2 As shown, the door sill post reinforcement assembly 100 also includes a front beam 4 and a torsion box 5. The front beam 4 and the torsion box 5 are connected to the inner plate 11 of the post, and the inner side of the reinforcement structure 3 is connected to the front beam 4 and the torsion box 5.

[0063] The inner side of the reinforcing structure 3 is connected to both the front crossbeam 4 and the torsion box 5. The front crossbeam 4 and the torsion box 5 are connected to the inner plate 11 of the column, thereby achieving an indirect connection between the inner side of the reinforcing structure 3 and the inner plate 11 of the column.

[0064] As an example, the sill pillar reinforcement assembly 100 also includes a front crossbeam 4 and a torsion box 5. The front crossbeam 4 extends along the left-right direction of the vehicle, and its outer side is connected to the pillar inner plate 11. The torsion box 5 is an anti-torsion component that can counteract torsional forces. Its outer side is also connected to the pillar inner plate 11. Both the front crossbeam 4 and the torsion box 5 are welded to the pillar inner plate 11. Since the reinforcement structure 3 is installed on the front side of the pillar 1, it is not easy to contact the pillar inner plate 11. The indirect connection between the front crossbeam 4 and the torsion box 5 reduces the difficulty of connecting the reinforcement structure 3 to the pillar inner plate 11. In the indirect connection mode, the force of the reinforcement structure 3 is first distributed to the front crossbeam 4 and the torsion box 5, and then jointly transmitted to the pillar inner plate 11. At the same time, the front crossbeam 4 can also diffuse some of the lateral force to other areas of the vehicle body, significantly reducing the risk of local stress overload and improving the overall failure resistance.

[0065] Among them, such as Figure 4 As shown, the front crossbeam 4 is provided with a first mounting hole 41, and the number of first mounting holes 41 can be one or more. After the inner reinforcing plate 31 and the outer reinforcing plate 32 are welded together, the first connecting hole 3121 and the second connecting hole 3221 can be aligned. After the first fastener passes through the second connecting hole 3221, the first connecting hole 3121 and the first mounting hole 41 in sequence, the inner side of the reinforcing structure 3 can be connected to the front crossbeam 4.

[0066] The torque box 5 is provided with a second mounting hole 51, and the number of second mounting holes 51 can be one or more. After the inner reinforcing plate 31 and the outer reinforcing plate 32 are welded together, the first connecting hole 3121 and the second connecting hole 3221 can be aligned. After the first fastener passes through the second connecting hole 3221, the first connecting hole 3121 and the second mounting hole 51 in sequence, the inner side of the reinforcing structure 3 can be connected to the torque box 5.

[0067] In one embodiment, the torque box 5 is disposed below the front crossbeam 4, and the upper part of the torque box 5 is connected to the lower part of the front crossbeam 4. Through the connection between the torque box 5 and the front crossbeam 4, they form a unified whole, sharing the load. The front crossbeam 4 can transmit force to the torque box 5, and similarly, the torque box 5 can also transmit force to the front crossbeam 4, avoiding the concentration of force on a single component or connection point. The torque box 5 is welded to the front crossbeam 4.

[0068] In one embodiment, such as Figure 3 As shown, the threshold 2 includes an inner threshold panel 21 and an outer threshold panel 22. The outer threshold panel 22 is connected to the outside of the inner threshold panel 21 and is connected to the outer panel 12 of the post. The inner threshold panel 21 is connected to the inner panel 11 of the post.

[0069] The sill 2 and the pillar 1 are key connection parts of the vehicle body. The inner sill plate 21 and the inner pillar plate 11 form an inner rigid connection, and the outer sill plate 22 and the outer pillar plate 12 form an outer rigid connection. The double fixation on the inner and outer sides reduces the loosening of the connection and jointly constrains the relative displacement of the sill 2 and the pillar 1, avoiding breakage due to concentrated load when connected on one side.

[0070] When the sill 2 is subjected to a vertical load, the force is transferred to the inner sill plate 21 and the inner pillar plate 11, and then to the outer pillar plate 12 via the outer sill plate 22. The pillar 1 then distributes the load to other areas of the vehicle body. When the pillar 1 is subjected to a lateral impact, the impact energy is transferred to the inner sill plate 21 via the inner pillar plate 11 and to the outer sill plate 22 via the outer pillar plate 12. The sill 2 can buffer the impact through its own lateral rigidity, so that the load is evenly distributed in the inner and outer paths, reducing the risk of local stress overload.

[0071] Among them, the outer sill plate 22 is welded to the outer column plate 12, and the inner sill plate 21 is welded to the inner column plate 11.

[0072] This application also provides a vehicle body structure, including the door sill pillar reinforcement assembly 100 of any of the above embodiments.

[0073] In this embodiment, the door sill reinforcement assembly 100 includes a pillar 1, a door sill 2, and a reinforcement structure 3. The pillar 1 is connected to the door sill 2, and the reinforcement structure 3 is disposed between the door sill 2 and the wheel along the front-rear direction of the vehicle. The reinforcement structure 3 is fixedly connected to the front side of the pillar 1.

[0074] In the event of a small offset collision, by utilizing the space between the sill 2 and the wheel, and by placing the reinforcing structure 3 in the space between the sill 2 and the wheel, the wheel can be effectively limited during the collision. This controls the posture of the wheel when it collides with the sill 2, preventing the wheel from excessively deflecting inward and directly impacting critical areas such as the base of the pillar 1 or the front end of the sill 2. It also reduces the impact of the wheel on the front end of the pillar 1 and the sill 2. This effectively improves the problem of separation of the inner and outer panels of the pillar 1 due to weld failure, which leads to bending and deformation of the sill 2 and the pillar 1. This enhances the strength of the vehicle body structure, reduces passenger compartment deformation, and ensures the survival space for the occupants.

[0075] This application also provides a vehicle, including the body structure described in the above embodiments.

[0076] The vehicle in this embodiment includes a body structure. The strength of the body structure is improved, which can reduce the deformation of the passenger compartment inside the vehicle and ensure the survival space for the occupants.
