Description

Technical Field

[0001] This invention relates to the field of vehicle technology, specifically providing an A-pillar structure, body structure, and vehicle for use in vehicles. Background Technology

[0002] With the rise of new energy vehicles and intensifying competition, vehicle exterior design has become increasingly important, gradually becoming a key factor for consumers when purchasing a car. Vehicle manufacturers are focusing on exterior design to attract consumers and differentiate themselves from competitors.

[0003] The A-pillar is the supporting pillar at the front of a vehicle, and its position is an important aspect of vehicle exterior design. To achieve a more harmonious body shape, some models choose to move the A-pillar forward. Moving the A-pillar forward improves the vehicle's aerodynamics, creates smoother front lines, and enhances the overall visual harmony—all crucial for the vehicle's appeal and brand image.

[0004] However, if the A-pillar is moved forward, and the A-pillar reinforcement plate does not move forward with it, the cavity formed between the A-pillar reinforcement plate and the outer side panel cannot be completely and effectively sealed; if the A-pillar reinforcement plate moves forward with it, the A-pillar is prone to bending and deformation when the vehicle is involved in an off-center collision, and the personal safety of the driver cannot be effectively guaranteed.

[0005] Accordingly, there is a need in the art for a new A-pillar structure, body structure, and vehicle for solving the above problems. Summary of the Invention

[0006] This invention aims to solve the aforementioned technical problem, namely, the poor sealing between the A-pillar reinforcement plate and the outer side panel when the A-pillar is moved forward. To this end, this invention provides an A-pillar structure for vehicles. This A-pillar structure for vehicles includes:

[0007] A door sill beam is provided along the length of the vehicle;

[0008] The A-pillar body is set along the height direction of the vehicle, and the bottom of the A-pillar body is connected to the door sill beam;

[0009] A-pillar reinforcement plate, connected to the front end of the A-pillar body, is positioned along the length of the vehicle, with the front end of the A-pillar reinforcement plate extending forward of the front end of the door sill beam;

[0010] The side panel is disposed on the outside of the sill beam, the A-pillar body, and the A-pillar reinforcing plate, and the sill beam, the A-pillar body, and the A-pillar reinforcing plate are all connected to the side panel. Along the length of the vehicle, the front end of the side panel is located between the front end of the A-pillar reinforcing plate and the front end of the sill beam, and the top of the side panel overlaps the A-pillar reinforcing plate, so that a stable sealing structure is formed between the side panel, the A-pillar reinforcing plate, and the A-pillar body.

[0011] In the specific embodiment of the A-pillar structure for vehicles described above, the outer side of a portion of the A-pillar reinforcing plate is in contact with the inner side of the side panel, and the outer side of the A-pillar body is in contact with the inner side of the side panel.

[0012] In the specific embodiment of the A-pillar structure for vehicles described above, the A-pillar structure further includes:

[0013] Vibration damping tower, wherein the A-column reinforcing plate is connected to the vibration damping tower;

[0014] The inner A-pillar panel is located inside the A-pillar body and the A-pillar reinforcing plate, and both the A-pillar body and the A-pillar reinforcing plate are connected to the inner A-pillar panel.

[0015] In the specific embodiment of the A-pillar structure for vehicles described above, the inner side of the A-pillar body and the inner side of the A-pillar reinforcing plate are in contact with the outer side of the inner A-pillar plate, and the A-pillar reinforcing plate, the outer side panel, the inner A-pillar plate, and the shock absorber tower cooperate to form an integrated sealed structure.

[0016] In the specific embodiment of the A-pillar structure for the vehicle described above, the distance between the front end of the side panel and the front end of the sill beam is greater than 40mm along the length of the vehicle.

[0017] In the specific embodiment of the A-pillar structure for vehicles described above, the strength of the A-pillar reinforcing plate is less than the strength of the A-pillar body.

[0018] In the specific embodiment of the A-pillar structure for vehicles described above, the thickness of the A-pillar reinforcing plate is less than the thickness of the A-pillar body.

[0019] In the specific embodiment of the A-pillar structure for vehicles described above, along the length of the vehicle, the connection between the A-pillar reinforcing plate and the A-pillar body is located on the rear side of the front end of the sill beam.

[0020] The present invention also provides a vehicle body structure. The vehicle body structure includes:

[0021] The A-pillar structure for vehicles as described above;

[0022] The upper beam of the A-pillar is connected to the A-pillar body and the outer side panel of the A-pillar structure. The outer side of the upper beam of the A-pillar is in contact with the inner side of the outer side panel.

[0023] The present invention also provides a vehicle. The vehicle includes the body structure as described above.

[0024] With the above technical solution, the A-pillar structure for vehicles provided by the present invention has its front end of the side outer panel located between the front end of the A-pillar reinforcing plate and the front end of the sill beam. That is, along the length of the vehicle, the front end of the A-pillar reinforcing plate is positioned ahead of the front end of the side outer panel. This arrangement allows the top of the side outer panel to overlap the outer side of the A-pillar reinforcing plate, thereby avoiding the formation of a cavity between the side outer panel and the A-pillar reinforcing plate. This results in a stable sealing structure between the side outer panel, the A-pillar reinforcing plate, and the A-pillar body, which facilitates the application of sealant in the subsequent painting process to achieve a completely effective and stable seal between the side outer panel, the A-pillar reinforcing plate, and the A-pillar body.

[0041] It should be noted that in the description of this invention, terms such as "upper," "lower," "left," "right," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the relevant devices or elements must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, ordinal numbers such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0043] Furthermore, it should be noted that in the description of this invention, the terms "up," "down," "front," and "rear" mentioned below refer to the up, down, front, and rear directions of the vehicle. These are generally relative to the normal driving state of the vehicle. Specifically, when the vehicle is driving normally, the direction towards the roof is "up," the direction towards the chassis is "down," the direction towards the front of the vehicle is "front," and the direction towards the rear of the vehicle is "rear."

[0044] In this invention, the vehicle can be an internal combustion engine vehicle or a new energy vehicle, and no limitation is made in this invention.

[0045] In some examples, the vehicle of the present invention may be a new energy vehicle.

[0046] For example, the vehicle of the present invention may be an electric vehicle.

[0047] A vehicle's exterior design can showcase its technological sophistication and aesthetic appeal. Many new energy vehicles employ unique exterior design elements to highlight their advanced technology and technological features, which can attract consumer attention and shape brand image. For example, moving the A-pillar forward can give the vehicle a streamlined shape, thereby improving aerodynamic performance, reducing wind resistance, and ultimately increasing energy efficiency and driving range.

[0048] When a vehicle adopts a forward-shifted A-pillar design, if the A-pillar reinforcement plate does not move forward accordingly, the upper front end of the side panel will be ahead of the front end of the A-pillar reinforcement plate, creating a cavity between the front end of the A-pillar reinforcement plate and the upper front end of the side panel. However, when filling the cavity between the front end of the A-pillar reinforcement plate and the upper front end of the side panel with a filling material (e.g., foam material), a complete seal cannot be achieved. Therefore, this will cause a seal failure in the A-pillar area, reducing the vehicle's sealing performance. This can lead to increased wind noise and technical problems such as rainwater or moisture entering the vehicle interior, causing corrosion, mold, or deformation of interior materials. Furthermore, the A-pillar seal failure can allow rainwater to seep into the vehicle's internal structural spaces, such as the electrical system or chassis components, posing a safety hazard.

[0049] like Figure 1 As shown, the present invention proposes an A-pillar structure 200 for vehicles. The A-pillar structure 200 for vehicles includes a sill beam 10, an A-pillar body 20, an A-pillar reinforcing plate 30, and a side panel 40.

[0050] The door sill beam 10 is installed along the length of the vehicle;

[0051] The A-pillar body 20 is set along the height direction of the vehicle, and the bottom of the A-pillar body 20 is connected to the door sill beam 10.

[0052] The A-pillar reinforcement plate 30 is connected to the front end of the A-pillar body 20. Along the length of the vehicle, the front end 30b of the A-pillar reinforcement plate 30 is positioned ahead of the front end 10a of the sill beam 10.

[0053] The side panel 40 is located on the outside of the sill beam 10, the A-pillar body 20 and the A-pillar reinforcing plate 30. The sill beam 10, the A-pillar body 20 and the A-pillar reinforcing plate 30 are all connected to the side panel 40. Along the length of the vehicle, the front end 40a of the side panel 40 is located between the front end 30b of the A-pillar reinforcing plate 30 and the front end 10a of the sill beam 10. The top of the side panel 40 overlaps with the A-pillar reinforcing plate 30, so that a stable sealing structure is formed between the side panel 40, the A-pillar reinforcing plate 30 and the A-pillar body 20.

[0054] In this embodiment, the front end 40a of the side outer panel 40 of the A-pillar structure 200 is located between the front end 30b of the A-pillar reinforcing plate 30 and the front end 10a of the sill beam 10. That is, along the length of the vehicle, the front end 30b of the A-pillar reinforcing plate 30 is positioned ahead of the front end 40a of the side outer panel 40, and the top of the side outer panel 40 overlaps with the A-pillar reinforcing plate 30. This arrangement allows the top of the side outer panel 40 to overlap with the outer side of the A-pillar reinforcing plate 30, thereby avoiding the formation of a cavity between the side outer panel 40 and the A-pillar reinforcing plate 30. This results in a stable sealing structure between the side outer panel 40, the A-pillar reinforcing plate 30, and the A-pillar body 20, which is beneficial for applying sealant in the subsequent painting process to achieve a completely effective and stable seal between the side outer panel 40, the A-pillar reinforcing plate 30, and the A-pillar body 20. In the subsequent painting process, sealant can be used to create a complete seal between the side panel 40, the A-pillar reinforcement plate 30 and the A-pillar body 20, effectively improving the sealing performance of the vehicle's A-pillar area.

[0055] In this embodiment, the sill beam 10, as a structural component of the vehicle, can increase the strength and rigidity of the vehicle body. When the vehicle is subjected to impact or collision, the sill beam 10 can disperse and absorb some of the energy, helping to protect the vehicle occupants and mitigate the impact of the collision on the vehicle structure. Furthermore, the sill beam 10 can also provide some protection in the event of a side collision. As part of the vehicle's side structure, it increases the rigidity of the vehicle body, thereby reducing the degree of vehicle deformation during a side collision and protecting the safety of the occupants.

[0056] In one possible implementation, the sill beam 10 is made of aluminum alloy material formed by an extrusion process.

[0057] In this embodiment, the A-pillar reinforcement plate 30 is connected to the front end of the A-pillar body 20 to increase the rigidity and strength of the vehicle, providing additional protection and stability. Furthermore, it can absorb and disperse collision energy, mitigating the impact of a collision on the safety of vehicle occupants and reducing injuries to them.

[0058] Furthermore, such as Figure 1 As shown, the outer side of part of the A-pillar reinforcement plate 30 is attached to the inner side of the side wall outer plate 40, and the outer side of the A-pillar body 20 is attached to the inner side of the side wall outer plate 40.

[0059] In this embodiment, the outer side of a portion of the A-pillar reinforcement plate 30 is fitted with the inner side of the side outer panel 40, and the outer side of the A-pillar body 20 is fitted with the inner side of the side outer panel 40. This arrangement effectively connects and fixes the structures between the A-pillar reinforcement plate 30 and the side outer panel 40, as well as between the A-pillar body 20 and the side outer panel 40, thereby increasing the structural strength and rigidity of the entire vehicle and providing better support and stability. Furthermore, this arrangement allows for a seamless fit between the outer side of the A-pillar reinforcement plate 30 and the inner side of the side outer panel 40, as well as between the outer side of the A-pillar body 20 and the inner side of the side outer panel 40, resulting in a smoother and more natural transition between the A-pillar reinforcement plate 30 and the side outer panel 40, thus enhancing the overall appearance and quality of the vehicle.

[0060] Furthermore, such as Figures 2 to 4 As shown, the A-column structure 200 may also include a shock absorber tower 50 and an inner A-column plate 60.

[0061] The A-column reinforcing plate 30 is connected to the damping tower 50;

[0062] The inner A-pillar panel 60 is located inside the A-pillar body 20 and the A-pillar reinforcing plate 30, and both the A-pillar body 20 and the A-pillar reinforcing plate 30 are connected to the inner A-pillar panel 60.

[0063] In this embodiment, the arrangement of the A-pillar reinforcement plate 30 connected to the shock absorber tower 50 increases the structural support of the front of the vehicle. By connecting the A-pillar reinforcement plate 30 and the shock absorber tower 50, additional support and stability can be provided, increasing the overall rigidity and strength of the vehicle. Furthermore, connecting the A-pillar reinforcement plate 30 and the shock absorber tower 50 can help disperse collision energy, reduce the impact of a collision on the vehicle's occupants, and thus contribute to improving vehicle safety.

[0064] In this embodiment, the A-pillar reinforcement plate 30 is directly connected to the shock absorber tower 50, eliminating the need for the outer plate of the upper front longitudinal beam, thereby enhancing the overall consistency of the vehicle's A-pillar area. The inner A-pillar plate 60 can be used to support and reinforce the structure of the vehicle's A-pillar area, and can also reduce the impact of external factors such as road noise and engine vibration on the vehicle interior, providing a quieter and more comfortable driving environment.

[0065] In one possible implementation, the A-column reinforcing plate 30 is welded to the damping tower 50.

[0066] In one possible implementation, the A-pillar reinforcement plate 30 is connected to the damping tower 50 via an automated screw assembly connection technology (e.g., FDS connection method).

[0067] Furthermore, such as Figure 3As shown, the inner side of the A-pillar body 20 and the A-pillar reinforcing plate 30 are attached to the outer side of the A-pillar inner plate 60, and the A-pillar reinforcing plate 30, the side outer plate 40, the A-pillar inner plate 60 and the shock absorber tower 50 work together to form an integrated sealed structure.

[0068] In this embodiment, the A-pillar reinforcing plate 30 extends forward, and the inner side of the A-pillar body 20 and the A-pillar reinforcing plate 30 fits against the outer side of the A-pillar inner plate 60. This allows the A-pillar reinforcing plate 30, the side outer plate 40 of the A-pillar structure 200, the A-pillar inner plate 60, and the shock absorber to form a sealed enclosure, effectively enhancing the sealing performance of the vehicle's A-pillar area. This effectively prevents external elements such as rainwater, mud, and dust from entering the A-pillar area and the vehicle interior. Furthermore, the formed sealed closed-loop structure can reduce noise transmission and improve the vehicle's sound insulation performance.

[0069] Furthermore, such as Figure 1 As shown, along the length of the vehicle, the distance D between the front end 40a of the side panel 40 and the front end 10a of the sill beam 10 is greater than 40mm.

[0070] In this embodiment, if the distance D between the front end of the side outer panel 40 and the front end of the sill beam 10 is greater than 40mm, it can be considered that the vehicle adopts a design scheme of moving the A-pillar forward.

[0071] In one possible implementation, the distance D between the front end 40a of the side panel 40 and the front end 10a of the sill beam 10 is 130mm.

[0072] Furthermore, such as Figure 2 As shown, the strength of the A-pillar reinforcement plate 30 is less than the strength of the A-pillar body 20.

[0073] In this embodiment, the strength of the A-pillar reinforcement plate 30 is less than the strength of the A-pillar body 20. This arrangement allows the vehicle to disperse some of the collision energy during an off-center collision, thus reducing the impact on the A-pillar body 20.

[0074] Furthermore, such as Figure 2 As shown, the thickness of the A-pillar reinforcement plate 30 is less than the thickness of the A-pillar body 20.

[0075] In this embodiment, the thickness of the A-pillar reinforcement plate 30 is less than the thickness of the A-pillar body 20. This arrangement allows the vehicle to disperse some of the collision energy during an off-center collision, reducing the impact on the A-pillar body 20.

[0076] When a vehicle experiences a side impact collision, the front end of the vehicle will be subjected to a powerful impact force. Since the A-pillar reinforcement plate 30 is located at the front end of the A-pillar body 20, the impact force is first transmitted to the A-pillar reinforcement plate 30 and then to the A-pillar body 20. Because the strength of the A-pillar reinforcement plate 30 is less than the strength of the A-pillar body 20, and / or the thickness of the A-pillar reinforcement plate 30 is less than the thickness of the A-pillar body 20, when the impact force is first transmitted to the A-pillar reinforcement plate 30, the A-pillar reinforcement plate 30 will absorb most of the impact energy and collapse, thereby reducing the impact energy reaching the A-pillar body 20, effectively mitigating the impact on the A-pillar body 20, and thus reducing the direct impact of the collision on the A-pillar body 20, reducing the risk of deformation and structural damage to the A-pillar body 20.

[0077] In one possible implementation, the strength of the A-pillar reinforcing plate 30 and the A-pillar body 20 can be tensile strength.

[0078] In some examples, the strength of the A-pillar reinforcement plate 30 is less than 270 MPa, while the strength of the A-pillar body 20 can be 500–800 MPa.

[0079] In one possible implementation, the thickness of the A-pillar reinforcement plate 30 can be 0.7 to 0.9 mm, and the thickness of the A-pillar body 20 can be 1.4 mm.

[0080] In some examples, the thickness of the A-pillar reinforcement plate 30 is 0.8 mm, and the thickness of the A-pillar body 20 is 1.4 mm.

[0081] Furthermore, such as Figure 2 and Figure 4 As shown, along the length of the vehicle, the connection 30a between the A-pillar reinforcement plate 30 and the A-pillar body 20 is located behind the front end 10a of the sill beam 10.

[0082] In this embodiment, the connection 30a between the A-pillar reinforcing plate 30 and the A-pillar body 20 is located behind the front end 10a of the sill beam 10. This arrangement allows the sill beam 10 to bear most of the impact energy received by the vehicle during a collision, thereby effectively preventing the A-pillar from deforming and improving the impact resistance of the A-pillar area.

[0083] In one possible implementation, in the event of an oblique collision, the impact force generated by the collision is first transmitted to the A-pillar reinforcement plate 30, which absorbs the impact energy and collapses. Since the connection 30a between the A-pillar reinforcement plate 30 and the A-pillar body 20 is located behind the front end 10a of the sill beam 10, the impact energy continues to be transmitted to the sill beam 10 along with the impact force. Because the sill beam 10 is made of aluminum alloy and has sufficient strength and rigidity through extrusion, after some of the impact energy is absorbed by the A-pillar reinforcement plate 30 in the later stages of the collision, most of the remaining impact energy is borne by the sill beam 10. This reduces the impact on the A-pillar body 20, lowers the risk of deformation and structural damage to the A-pillar body 20, and effectively reduces the risk of injury to the occupants of the vehicle during an oblique collision.

[0084] In one possible implementation, the connection 30a between the A-pillar reinforcing plate 30 and the A-pillar body 20 can be a vertical connection seam, and it is in the shape of a straight line.

[0085] In some examples, the connection seam between the A-pillar reinforcement plate 30 and the A-pillar body 20 is located 20 mm behind the front end 10a of the sill beam 10.

[0086] Furthermore, such as Figure 2 and Figure 4 As shown, the A-pillar reinforcement plate 30 is connected to the A-pillar body 20 by laser welding.

[0087] In this embodiment, laser welding technology can weld A-pillar reinforcing plates 30 of different thicknesses, strengths and / or materials to the A-pillar body 20, thereby achieving different thicknesses and / or strengths in the vehicle A-pillar structure 200, and allowing arbitrary splicing according to strength and functional design needs, thus optimizing the A-pillar structure 200 and the production and assembly process.

[0088] In one possible implementation, the A-pillar reinforcement plate 30 is made of a low-strength steel plate that can be laser-welded to hot-formed steel, and the A-pillar body 20 can be hot-formed steel.

[0089] In some examples, the A-pillar reinforcement plate 30 can be made of Ductidor450 material, and the A-pillar body 20 can be made of PHD950Y1300T material.

[0090] For example, the A-pillar reinforcement plate 30 can be made of Ductidor450 t0.7 material, and the A-pillar body 20 can be made of PHD950Y1300T t1.4 material.

[0091] like Figure 3 and Figure 4As shown, the present invention also proposes a vehicle body structure 300. This vehicle body structure 300 includes an A-pillar structure 200 and an upper A-pillar beam 210 as described in the above embodiments.

[0092] The upper beam 210 of the A-column is connected to the A-column body 20 and the outer side panel 40 of the A-column structure 200. The outer side of the upper beam 210 of the A-column is in contact with the inner side of the outer side panel 40.

[0093] In this embodiment, the upper side beam 210 of the A-pillar is connected to the A-pillar body 20 and the side outer panel 40 of the A-pillar structure 200. This arrangement can increase the strength and rigidity of the overall structure of the A-pillar area of ​​the vehicle, and can withstand the impact force generated during a frontal collision, dispersing the impact force to the A-pillar and other parts of the vehicle, thereby effectively protecting the personal safety of the occupants.

[0094] In one possible implementation, in the event of a biased collision, the impact force is first transmitted to the A-pillar reinforcement plate 30. The A-pillar reinforcement plate 30, with its good deformation capacity, absorbs the impact energy and collapses. Since the connection seam between the A-pillar reinforcement plate 30 and the A-pillar body 20 is located behind the front end 10a of the sill beam 10, the impact energy continues to be transmitted to the sill beam 10 as the impact force continues to be transmitted. Because the sill beam 10 is made of aluminum alloy and formed through an extrusion process, it has sufficient strength and rigidity. In the later stages of the collision, after some of the impact energy is absorbed by the A-pillar reinforcement plate 30, most of the remaining impact energy is borne by the sill beam 10. This maximizes the absorption of impact energy, thereby reducing the impact on the A-pillar body 20, lowering the risk of deformation and structural damage to the A-pillar body 20, and effectively reducing the impact energy transmitted to the upper A-pillar beam 210. This makes the upper A-pillar beam 210 less prone to deformation in the event of a biased collision, thus effectively reducing the risk of injury to occupants during a biased collision.

[0095] In one possible implementation, the upper side beam 210 of the A-pillar is connected to the A-pillar body 20 by welding or bolting.

[0096] The present invention also proposes a vehicle. The vehicle includes a body structure 300 as described in the above embodiments.

[0097] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
