Abstract
Description
Technical Field
[0001] The present application relates to the technical field of vehicle structures, and in particular to a vehicle body pillar reinforcement structure, a vehicle body pillar, and a vehicle. Background Art
[0002] The body pillars are a crucial component of the vehicle's body and serve as its primary support structure. They not only provide structural support but also disperse the force of a collision, protecting the occupants. For example, the A-pillars are typically located on either side of the windshield, connecting the engine compartment to the passenger compartment. In a head-on collision, the A-pillars disperse the force of the impact toward the roof, sides, and floor, maintaining the passenger compartment intact and preventing intrusion by wheels, suspension, and other components.
[0003] Vehicle body pillars are typically equipped with reinforcement structures to improve their effectiveness in withstanding and distributing impact forces during a collision, thereby protecting the occupants' living space. These reinforcement structures are typically made of high-strength metal and are typically thick, which increases the weight of the vehicle body pillar and hinders lightweighting. To balance structural strength and weight, related technologies employ reinforcement plates and support plates attached to local reinforcement plates as reinforcement structures. However, the connection strength between the reinforcement plates and the support plates in these reinforcement structures is insufficient, resulting in insufficient structural strength of the vehicle body pillars and poor deformation resistance of the vehicle body pillars.

[0044] The embodiment of the present application provides a vehicle body pillar reinforcement structure 10, which is applicable to a vehicle body pillar 100, for example, an A-pillar, a B-pillar, a C-pillar, a D-pillar, etc. Figure 1 and Figure 2 The figure shows the relevant structure of the vehicle body pillar 100 to which the vehicle body pillar reinforcement structure 10 provided in the embodiment of the present application is applicable. Figure 1 A schematic diagram of the local structure of the vehicle. Figure 2 for Figure 1 Section view along AA. Figure 2 In the illustrated example, the vehicle body pillar 100 includes a side panel outer panel 30 , a side panel inner panel 20 and a vehicle body pillar reinforcement structure 10 . The vehicle body pillar reinforcement structure 10 is disposed between the side panel inner panel 20 and the side panel outer panel 30 .
[0045] The following combination Figures 3 to 5 The vehicle body pillar reinforcement structure 10 according to an embodiment of the present application will be described in detail.
[0046] Figure 3 1 is a side view of the coordination between the reinforcement plate 1 and the support member 2 in the vehicle body pillar reinforcement structure 10 provided in an exemplary embodiment of the present application; Figure 4 is a schematic structural diagram of a support member 2 provided in an exemplary embodiment of the present application; Figure 51 is a top view of the coordination between the reinforcement plate 1 and the support member 2 in the vehicle body pillar reinforcement structure 10 provided in an exemplary embodiment of the present application.
[0047] Reference Figures 3 to 5 The vehicle body pillar reinforcement structure 10 includes a reinforcement plate 1 and a support member 2 .
[0048] The reinforcement plate 1 is used to increase the strength of the vehicle body pillar 100. In the event of a head-on collision, side collision, or rollover, the reinforcement plate 1 can enhance the impact resistance of the vehicle body pillar 100 to protect the lives of the occupants. The main portion of the reinforcement plate 1 can be constructed in a flat plate shape. The main portion of the reinforcement plate 1 can also be bent into a complex structure with multiple side walls. For example, the cross-section of the main portion of the reinforcement plate 1 can be L-shaped, U-shaped, or other shapes. The reinforcement plate 1 can be formed using a structure composed of multiple layers of steel plates or a special stamping process to increase its strength. The material of the reinforcement plate 1 can include, but is not limited to, dual-phase steel (DP steel), transformation-induced plasticity steel (TRIP steel), etc. The support member 2 serves as an auxiliary support, providing additional support for the reinforcement plate 1, thereby increasing the strength of the vehicle body pillar 100. The support member 2 includes a main body 25 and a first flange 21 , a second flange 22 and a third flange 23 circumferentially arranged along the main body 25 . The first flange 21 , the second flange 22 and the third flange 23 are all connected to the reinforcing plate 1 .
[0049] The main body 25 can retain the basic form of a plate, having a certain length, width, and thickness. The main body 25 provides primary support. The first flange 21, the second flange 22, and the third flange 23 can be vertical surfaces extending from the edge of the main body 25. The first flange 21, the second flange 22, and the third flange 23 can enhance the strength of the support member 2 while providing more possibilities for connecting the support member 2 to the reinforcing plate 1. The material of the support member 2 can include, but is not limited to, steel, aluminum alloy, etc.
[0050] It should be noted that, when the main body of the reinforcing plate 1 is plate-shaped, the reinforcing plate 1 can be connected via the end faces of the first flange 21, the second flange 22, and the third flange 23. In embodiments where the reinforcing plate 1 includes multiple side walls, the first flange 21, the second flange 22, and the third flange 23 can be stacked with different side walls of the reinforcing plate 1, thereby facilitating the connection between the reinforcing plate 1 and the support member 2.
[0051] In a specific application, the reinforcing plate 1 may extend in the height direction of the vehicle, and the main body 25 of the support member 2 may be constructed as a rectangle, with the length of the main body 25 extending in the front-rear direction of the vehicle and the width of the main body 25 extending in the left-right direction of the vehicle.
[0052] The first flange 21 , the second flange 22 , and the third flange 23 may be connected to the reinforcing plate 1 in a manner that includes at least one of welding, screwing, and riveting.
[0053] In some embodiments, the first flange 21 is welded to the reinforcing plate 1 to improve the connection stability between the first flange 21 and the reinforcing plate 1 .
[0054] In some embodiments, the second flange 22 is welded to the reinforcing plate 1 to improve the connection stability between the second flange 22 and the reinforcing plate 1 .
[0055] In some embodiments, the second flange 22 is welded to the reinforcing plate 1 to improve the connection stability between the third flange 23 and the reinforcing plate 1 .
[0056] On the basis of welding, the first flange 21, the second flange 22 and the third flange 23 can also be provided with connection holes for use with connecting parts (bolts, screws, etc.) to further enhance the connection stability between these flanges and the reinforcing plate 1.
[0057] In the above embodiment, by connecting the first flange 21, the second flange 22, and the third flange 23 to the reinforcing plate 1, the support member 2 is connected to the reinforcing plate 1 at multiple different positions. This improves the connection strength between the reinforcing plate 1 and the support member 2, thereby improving the overall strength of the vehicle body pillar reinforcement structure 10 and thereby enhancing the deformation resistance of the vehicle body pillar 100.
[0058] In some embodiments, the support member 2 further includes a fourth flange 24. The first flange 21, the second flange 22, the third flange 23, and the fourth flange 24 are sequentially adjacently disposed along the circumference of the main body 25. The first flange 21 and the third flange 23 are disposed opposite each other along a first direction X, and the second flange 22 and the fourth flange 24 are disposed opposite each other along a second direction Y, where the second direction Y intersects the first direction X. It will be appreciated that the support member 2 is provided with flanges on all four sides, and such an arrangement can provide a support member 2 with greater strength.
[0059] In practical applications, the first direction X may be parallel to the length direction of the vehicle body, and the second direction Y may be parallel to the width direction of the vehicle body.
[0060] In practical applications, the fourth flange 24 may not be connected to other components or structures. That is, the fourth flange 24 is used to increase the structural strength of the support member 2 and is not used to connect to other structures. Since the fourth flange 24 is not connected to other structures, the end of the fourth flange 24 away from the main body 25 is suspended in the air, and the vibration amplitude of the fourth flange 24 is relatively large. In order to alleviate the vibration of the fourth flange 24 and improve the modal state of the support member 2, the size of the fourth flange 24 can be reduced. For example, the width of the fourth flange 24 can be smaller than that of the other flanges. The dimension of the fourth flange 24 along the thickness direction of the main body 25 is the width of the fourth flange 24.
[0061] The first flange 21 , the second flange 22 , the third flange 23 and the fourth flange 24 can be turned toward the same side of the main body 25 , or one or more flanges can be turned toward one side of the main body 25 and the remaining flanges can be turned toward the other side of the main body 25 .
[0062] In some embodiments, as Figure 4 As shown, the first flange 21, the second flange 22, the third flange 23, and the fourth flange 24 are located on the same side of the main body 25. It can be understood that for the support member 2, the flanges on the same side help control the thickness of the support member 2 compared to the flanges on the opposite sides, making the support member 2 thinner. As a result, the support member 2 occupies less space when used in the vehicle body pillar 100, thereby facilitating the assembly of other components.
[0063] Reference Figure 4 In some embodiments, in order to alleviate stress concentration at the connection positions between each flange and the main body 25, the support member 2 may further include a first transition portion 211, a second transition portion 221, a third transition portion 231 and a fourth transition portion 241.
[0064] The first flange 21 and the main body 25 are smoothly transitioned through the first transition portion 211, and the second flange 22 and the main body 25 are smoothly transitioned through the second transition portion 221. The third flange 23 and the main body 25 are smoothly transitioned through the third transition portion 231. The fourth flange 24 and the main body 25 are smoothly transitioned through the fourth transition portion 241.
[0065] In some embodiments, the first transition portion 211, the second transition portion 221, the third transition portion 231 and the fourth transition portion 241 are continuously arranged along the circumference of the main body 25. It is understood that the transition portions connecting the flanges to the main body 25 are connected in sequence from beginning to end without interruption.
[0066] In the embodiment of the present application, the transition portions connecting the flanges to the main body 25 are continuously arranged, so that the support member 2 with higher overall strength can be obtained.
[0067] Optionally, the first transition portion 211 , the second transition portion 221 , the third transition portion 231 and the fourth transition portion 241 all transition to the main body portion 25 in a rounded manner.
[0068] Reference Figure 4 In some embodiments, the main body 25 is provided with a first reinforcing rib 26. The first reinforcing rib 26 can be provided in a strip-shaped, grid-shaped, or other structure connected to the main body 25. The first reinforcing rib 26 and the main body 25 can be integrally formed. The first reinforcing rib 26 can be a solid structure or a hollow structure. The first reinforcing rib 26 can also be a structure stamped from the main body 25.
[0069] In some embodiments, the main body 25 is further provided with a second reinforcing rib 27, the extension direction of which intersects with the extension direction of the first reinforcing rib 26. The formation of the second reinforcing rib 27 can refer to the formation of the first reinforcing rib 26.
[0070] In one embodiment, the extending direction of the first reinforcing rib 26 is perpendicular to the extending direction of the second reinforcing rib 27 .
[0071] In one embodiment, the first reinforcing rib 26 extends from the first flange 21 toward the third flange 23. The second reinforcing rib 27 extends from the second flange 22 toward the fourth flange 24. In practical applications, the first reinforcing rib 26 can extend along the length of the vehicle body, and the second reinforcing rib 27 can extend along the width of the vehicle body. The first reinforcing rib 26, together with the first and third flanges 21, 23, absorbs impact forces in the front-to-rear direction of the vehicle body, while the second reinforcing rib 27, together with the second and fourth flanges 22, 24, absorbs impact forces in the left-to-right direction of the vehicle body.
[0072] In some embodiments, the first flange 21, the second flange 22, the third flange 23, the fourth flange 24, the first reinforcing rib 26, and the second reinforcing rib 27 are located on the same side of the main body 25. The main body 25 is stamped to form a convex portion on the side of the main body 25 facing the four flanges, and a concave portion corresponding to the convex portion is formed on the side of the main body 25 facing away from the four flanges. The convex portion may include the first reinforcing rib 26 and the second reinforcing rib 27 described above.
[0073] In some embodiments, the strength of the support member 2 can be further improved by providing the first reinforcement rib 26 and / or the second reinforcement rib 27 , so that the support member 2 can better disperse stress when subjected to impact force, thereby improving the overall strength of the vehicle body pillar reinforcement structure 10 .
[0074] In addition, the first reinforcing rib 26 and / or the second reinforcing rib 27 can also alleviate the risk of fatigue cracks caused by vibration of the support member 2. Specifically, the first reinforcing rib 26 and / or the second reinforcing rib 27 can be arranged near the connection position between other components and the reinforcing plate 1. For example, the reinforcing plate 1 is provided with a door hinge mounting point, and the support member 2 can be arranged near the door hinge mounting point. For another example, the reinforcing plate 1 is provided with a door limiter mounting point, and the support member 2 can be arranged near the door limiter mounting point. The support member 2 is arranged near the door hinge mounting point or the door limiter mounting point to reinforce the area around the mounting point. The first reinforcing rib 26 and / or the second reinforcing rib 27 increase the strength of the support member 2, thereby alleviating the vibration transmitted from the mounting point to the reinforcing plate, which helps to improve the problem of abnormal noise from the door connected to the vehicle body pillar reinforcement structure 10.
[0075] For example, Figure 3As shown, the reinforcement plate 1 can be provided with a first connecting portion 15 and a second connecting portion 16, which are spaced apart along the height direction of the vehicle body. The first connecting portion 15 is used to connect to one door hinge, and the second connecting portion 16 is used to connect to another door hinge. The support member 2 is provided between the first connecting portion 15 and the second connecting portion 16. The support member 2 can strengthen the area near the first connecting portion 15 and the second connecting portion 16, thereby improving the overall strength of the vehicle body pillar 100.
[0076] Reference Figure 4 In some embodiments, the support member 2 is further provided with a stress relief hole 28, which passes through the first reinforcing rib 26, or the second reinforcing rib 27, or both the first reinforcing rib 26 and the second reinforcing rib 27. The stress relief hole 28 is used to relieve stress when the support member 2 is deformed by an impact force.
[0077] If the support member 2 is located near the connection between other components and the reinforcing plate 1, vibrations of the other components will cause the reinforcing plate 1 to vibrate, and this vibration will be transmitted to the support member 2, causing fatigue in the support member 2. Therefore, by providing the first reinforcing rib 26 and / or the second reinforcing rib 27 on the main body 25 of the support member 2, the risk of fatigue cracks in the support member 2 caused by vibrations of other components being transmitted to the support member 2 through the reinforcing plate 1 can be reduced.
[0078] Reference Figure 5 In some embodiments, the reinforcing plate 1 includes a first side panel 11, a second side panel 12, and a third side panel 13. The first side panel 11 and the third side panel 13 are arranged opposite to each other, and the second side panel 12 connects the first side panel 11 and the third side panel 13. The first side panel 11, the second side panel 12, and the third side panel 13 define a cavity 14. The support member 2 is arranged in the cavity 14. The first flange 21 is stacked with the first side panel 11, and the first flange 21 is connected to the first side panel 11. The second flange 22 is stacked with the second side panel 12, and the second flange 22 is connected to the second side panel 12. The third flange 23 is stacked with the third side panel 13, and the third flange 23 is connected to the third side panel 13. The main body 25 is roughly parallel to the cross-sectional direction of the reinforcing plate 1.
[0079] In the embodiment of the present application, the main body 25 can provide support force for the reinforcing plate 1 along the direction relative to the first flange 21 and the third flange 23, and provide support force for the reinforcing plate 1 along the direction relative to the second flange 22 and the fourth flange 24.
[0080] In order to facilitate the connection between the support member 2 and the reinforcement plate 1, the cavity 14 can be set to an open structure. In actual application, the open side of the cavity 14 faces the interior of the vehicle and is covered by the side inner panel 20. The cavity 14 can be understood as an inner cavity.
[0081] The first side panel 11 may further have a flange at one end away from the second side panel 12, and the first side panel 11 is connected to the side inner panel 20 via the flange. The third side panel 13 may further have a flange at one end away from the second side panel 12, and the third side panel 13 is connected to the side inner panel 20 via the flange.
[0082] Reference Figure 2 The present application also provides a vehicle pillar 100. The vehicle pillar 100 includes the vehicle pillar reinforcement structure 10 provided in any of the aforementioned embodiments. Because the vehicle pillar 100 includes the vehicle pillar reinforcement structure 10, the vehicle pillar 100 has the beneficial effects of the vehicle pillar reinforcement structure 10. For the sake of brevity, these effects are not further detailed here.
[0083] Reference Figure 2 In some embodiments, the vehicle body pillar 100 further includes a side panel inner panel 20 and a side panel outer panel 30 .
[0084] The side panel outer panel 30 is disposed opposite to the side panel inner panel 20 . The vehicle body pillar reinforcement structure 10 is disposed between the side panel inner panel 20 and the side panel outer panel 30 and is connected to the side panel inner panel 20 and the side panel outer panel 30 .
[0085] The side panel inner panel 20 is located inside the reinforcement panel 1. It also reinforces the vehicle body pillar 100 and provides a mounting base for interior components. In the event of a collision, the side panel inner panel 20 and the reinforcement panel 1 absorb and disperse the impact energy, protecting the safety of the vehicle's passengers.
[0086] The side panels 30, located outside the reinforcement plate 1, are an integral part of the vehicle's exterior appearance. They not only serve a decorative purpose but, together with other exterior body panels, contribute to the vehicle's overall appearance. In the event of a collision, the side panels 30 also help absorb impact energy to a certain extent, minimizing injuries to passengers.
[0087] The side outer panel 30 can be made of thin steel plate or other metal materials, and the surface is painted to improve its corrosion resistance and aesthetics.
[0088] When the fourth flange 24 is not connected to any other structure, it hangs in the air and is easily excited. In other words, it is susceptible to vibrations due to external forces or energy. If the support member 2 is located in the cavity 14, the cavity 14 will amplify the vibration sound, causing the door connected to the body pillar reinforcement structure 10 to vibrate and produce abnormal noise. By providing the first reinforcing rib 26 and / or the second reinforcing rib 27 on the main body 25 of the support member 2, the vibration amplitude of the fourth flange 24 is reduced, thereby reducing noise and helping to alleviate the problem of abnormal door noise connected to the body pillar reinforcement structure 10.
[0089] Reference Figure 2 In some embodiments, the vehicle body pillar 100 is an A-pillar, which further includes a side A-pillar connector 40. The side A-pillar connector 40 is connected to the reinforcement plate 1 and the support member 2. The side A-pillar connector 40 is connected to the vehicle body structure, thereby connecting the reinforcement plate 1 and the vehicle body pillar 100 to the vehicle body.
