[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on the Chinese patent application with application number 202310776868.X and application date June 28, 2023, and claims the priority of the above-mentioned Chinese patent application. The entire content of the above-mentioned Chinese patent application is hereby introduced into this application as a reference. Technical Field

[0004] With the rapid development of the economy and the automotive industry, people's demands for vehicle aesthetics and comfort are becoming increasingly higher. Consequently, B-pillar-less vehicles are becoming increasingly common. The B-pillar is a crucial component for enhancing vehicle safety. In the event of a roll or overturn, it effectively prevents the cockpit from being squeezed and deformed, protecting the occupants.

[0005] The elimination of the B-pillar creates a greater load bearing capacity for the vehicle's upper side rails. Current B-pillar-less vehicles often feature sliding doors. The layout of the sliding door's upper guide rails results in insufficient support space in the upper side rails, resulting in lower structural strength and, consequently, lower vehicle reliability. Consequently, improvements to the upper side rail structure are urgently needed.

[0006] Summary of the Invention

[0007] In view of the above problems, the present application provides a roof side rail structure, a body structure and a vehicle, which can effectively improve the structural strength of the roof side rail and improve the reliability of the vehicle.

[0008] In a first aspect, an embodiment of the present application provides a roof rail structure, which includes a roof rail inner plate, a roof rail reinforcement plate, a guide rail mounting plate, a side panel outer plate, and a guide rail disposed on the guide rail mounting plate. The roof rail inner plate, the roof rail reinforcement plate, and the guide rail mounting plate are connected end to end to form a first cavity. The side panel outer plate is bent in a direction away from the first cavity and connected to the roof rail reinforcement plate to form a second cavity. The guide rail is located on a side of the guide rail mounting plate that is away from the first cavity in the first direction. Along the first direction, the projection of the first cavity at least partially overlaps with the projection of the second cavity, and the projection of the guide rail is located within the overlapping portion of the projection of the first cavity and the projection of the second cavity.

[0009] In some embodiments of the first aspect, the upper side beam structure also includes an installation area for installing a guide rail, the installation area is located on the side of the guide rail mounting plate away from the first cavity, and the cross-sectional area of ​​the first cavity along the first direction is larger than the cross-sectional area of ​​the installation area along the first direction.

[0010] In some embodiments of the first aspect, the roof rail inner plate, the roof rail reinforcement plate, the guide rail mounting plate and the side panel outer plate are an integrally formed structure.

[0011] In some embodiments of the first aspect, the first connecting portion of the side panel and the upper side beam reinforcement plate extends along the first direction, and the orthographic projection of the first connecting portion along the second direction covers at least part of the orthographic projection of the guide rail along the second direction.

[0012] In some embodiments of the first aspect, along the second direction, a projection of the guide rail is located within a projection of the first connecting portion.

[0013] In some embodiments of the first aspect, the guide rail mounting plate includes a first mounting plate and a second mounting plate, and the roof side rail reinforcement plate, the first mounting plate, the second mounting plate and the roof side rail inner plate are connected end to end to form a first cavity.

[0014] In some embodiments of the first aspect, a support plate is provided inside the first cavity, and the support plate is connected between inner walls of the first cavity along the first direction.

[0015] And / or, the support plate is connected between inner walls of the first cavity along the second direction.

[0016] In some embodiments of the first aspect, a dimension h1 of the first cavity along the first direction satisfies: h1 ≥ 45 mm, a dimension h2 of the first cavity along the second direction satisfies: h2 ≥ 10 mm, and the second direction is perpendicular to the first direction.

[0017] In a second aspect, an embodiment of the present application provides a vehicle body structure, which includes the upper side rail structure provided by any embodiment of the first aspect.

[0018] In a third aspect, an embodiment of the present application provides a vehicle, which includes the vehicle body structure provided by the implementation method of the second aspect.

[0019] The roof rail structure, vehicle body structure, and vehicle provided by the present application, on the one hand, have a projection of the first cavity and the projection of the second cavity at least partially overlap along a first direction. This allows the cross-sectional area of ​​the energy-absorbing cavity of the roof rail structure to be increased by the superposition of the first and second cavities, enabling the roof rail structure to withstand greater impact loads and effectively improving the structural strength of the roof rail structure. On the other hand, the projection of the first cavity and the projection of the second cavity at least partially overlap along the first direction, and the projection of the guide rail is located within the overlapping portion of the projection of the first and second cavities.

For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components.

[0034] With the rapid development of the economy and the automotive industry, people's demands for vehicle aesthetics and comfort are becoming increasingly higher. Consequently, B-pillar-less vehicles are becoming increasingly common. The B-pillar is a crucial component for enhancing vehicle safety. In the event of a roll or overturn, it effectively prevents the cockpit from being squeezed and deformed, protecting the occupants.

[0035] The inventors of this application noted that the removal of the B-pillar structure places greater loads on the vehicle's roof rails. Currently, many B-pillar-less vehicles are equipped with sliding doors. The layout of the sliding door's upper guide rails results in insufficient support in the roof rails, resulting in lower structural strength and, consequently, reduced vehicle safety.

[0036] The inventors of this application have discovered that by arranging the guide rail away from the upper side beam reinforcement plate along the first direction, a certain space can be created between the guide rail and the upper side beam reinforcement plate, thereby making the first cavity formed by the end-to-end connection of the upper side beam inner plate, the upper side beam reinforcement plate and the guide rail mounting plate have a larger size in the first direction, reducing the restriction of the guide rail on the setting space of the first cavity, so that the first cavity has a larger cross-sectional area along the first direction, thereby being able to withstand a larger load, effectively improving the structural strength of the upper side beam, and thereby improving the safety of the vehicle.

[0037] In order to solve the problems of the existing technology, the embodiment of the present application provides an upper side beam structure, a body structure and a vehicle, which can effectively improve the structural strength of the upper side beam and thus improve the safety of the vehicle. The upper side beam structure provided by the embodiment of the present application is first introduced below.

[0038] Figure 1 is a structural schematic diagram of an upper side beam structure provided in some embodiments of the present application; Figure 2 is a cross-sectional structural schematic diagram of an upper side beam structure along AA provided in some embodiments of the present application; Figure 3 is a cross-sectional structural schematic diagram of the connection method between the guide rail and the guide rail mounting plate in an upper side beam structure provided in some embodiments of the present application.

[0039] As shown in Figures 1 to 3, an embodiment of the present application provides a roof rail structure 100, including a roof rail inner plate 10, a roof rail reinforcement plate 20, a guide rail mounting plate 30, a side panel outer plate 60, and a guide rail 40 provided on the guide rail mounting plate 30. The roof rail inner plate 10, the roof rail reinforcement plate 20, and the guide rail mounting plate 30 are connected end to end to form a first cavity 50. The side panel outer plate 60 is bent in a direction away from the first cavity 50 and connected to the roof rail reinforcement plate 20 to form a second cavity 70. The guide rail 40 is located on a side of the guide rail mounting plate 30 away from the first cavity 50 along a first direction X. Along the first direction X, the projection of the first cavity 50 at least partially overlaps with the projection of the second cavity 70, and the projection of the guide rail 40 is located in the overlapping portion of the projection of the first cavity 50 and the projection of the second cavity 70.

[0040] In the embodiment of the present application, the upper side rail structure 100 may be a side rail structure on the top of the vehicle, and the first direction X may be understood as the height direction of the vehicle.

[0041] For example, one end of the roof side rail inner panel 10 is connected to one end of the roof side rail reinforcement plate 20, the other end of the roof side rail inner panel 10 is connected to one end of the guide rail mounting plate 30, and the other end of the roof side rail reinforcement plate 20 is connected to the other end of the guide rail mounting plate 30, so that the roof side rail inner panel 10, the roof side rail reinforcement plate 20 and the guide rail mounting plate 30 are connected end to end, and a first cavity 50 is formed inside the roof side rail inner panel 10, the roof side rail reinforcement plate 20 and the guide rail mounting plate 30. The first cavity 50 is the main load-bearing cavity of the roof side rail structure 100. The larger the cavity space of the first cavity 50, the greater the load it can withstand.

[0042] It should be noted that the roof side rail inner plate 10, the roof side rail reinforcement plate 20, and the guide rail mounting plate 30 can be connected end to end in a clockwise direction or in a counterclockwise direction. The roof side rail inner plate 10, the roof side rail reinforcement plate 20, and the guide rail mounting plate 30 are all curved panels in an irregularly bent state. This application does not limit the specific structural shape and connection sequence of the roof side rail inner plate 10, the roof side rail reinforcement plate 20, and the guide rail mounting plate 30, and they can be set according to actual conditions.

[0043] Optionally, the roof side rail inner plate 10, the roof side rail reinforcement plate 20, the guide rail mounting plate 30, and the guide rail 40 may all be made of metal materials, such as stainless steel, aluminum, or titanium. The roof side rail inner plate 10, the roof side rail reinforcement plate 20, the guide rail mounting plate 30, and the guide rail 40 may be connected by, but not limited to, welding, riveting, or bolting.

[0044] Exemplarily, one end of the side outer panel 60 is connected to one end of the upper side beam reinforcement plate 20, the other end of the side outer panel 60 is connected to the other end of the upper side beam reinforcement plate 20, and the side outer panel 60 is bent in a direction away from the first cavity 50 to form a second cavity 70 between the side outer panel 60 and the upper side beam reinforcement plate 20.

[0045] As described above, one end of the top side rail reinforcement plate 20 is also connected to the top side rail inner plate 10. At the connection point where the top side rail reinforcement plate 20 and the top side rail inner plate 10 are connected, the side panel outer panel 60, the top side rail reinforcement plate 20 and the top side rail inner plate 10 form a sandwich structure in which the top side rail reinforcement plate 20 is located in the middle, and the side panel outer panel 60 and the top side rail inner plate 10 are located on both sides of the top side rail reinforcement plate 20 along the thickness direction. Similarly, the other end of the top side rail reinforcement plate 20 is also connected to the guide rail mounting plate 30. At the connection point where the top side rail reinforcement plate 20 and the guide rail mounting plate 30 are connected, the side panel outer panel 60, the top side rail reinforcement plate 20 and the top side rail inner plate 10 form a sandwich structure in which the top side rail reinforcement plate 20 is located in the middle, and the side panel outer panel 60 and the guide rail mounting plate 30 are located on both sides of the top side rail reinforcement plate 20 along the thickness direction. The above arrangement can improve the structural strength of the connection between the side panel outer panel 60 , the roof side rail reinforcement plate 20 , the roof side rail inner panel 10 and the guide rail mounting plate 30 , thereby improving the overall reliability of the roof side rail structure 100 .

[0046] The side outer panel 60 is bent in a direction away from the first cavity 50, so that the second cavity 70 is located on the side of the first cavity 50 away from the guide rail 40. The second cavity 70 also has a load-bearing capacity. The larger the cavity space of the second cavity 70, the greater the load it can withstand. At the same time, the second cavity 70 can also improve the bending and torsional strength of the roof rail structure 100.

[0047] Optionally, the side panel 60 can be made of a metal material, such as stainless steel, aluminum, or titanium. The side panel 60 is an irregularly curved panel. The connection between the side panel 60 and the roof rail reinforcement plate 20, and between the guide rail mounting plate 30 and the guide rail 40, can be, but is not limited to, welding, riveting, or bolting.

[0048] The guide rail 40 is mounted on the guide rail mounting plate 30. The guide rail 40 occupies a portion of the space within the roof rail structure 100, thereby limiting the space available for the first cavity 50. In the embodiment of the present application, the guide rail 40 is located on the side of the first cavity 50 facing away from the second cavity 70 along the first direction X. That is, the guide rail 40 is located away from the roof rail reinforcement plate 20 along the first direction X. In other words, the roof rail reinforcement plate 20 and the guide rail 40 are located on opposite sides of the first cavity 50 along the first direction X. This creates a certain amount of space between the guide rail 40 and the roof rail reinforcement plate 20, thereby giving the first cavity 50 a larger size along the first direction X. It should be noted that in the embodiment of the present application, the guide rail 40 is first installed on the guide rail mounting plate 30 after the roof rail inner panel 10, the roof rail reinforcement plate 20, and the guide rail mounting plate 30 are connected. This avoids connection difficulties caused by the guide rail 40 obstructing the connection between the roof rail reinforcement plate 20 and the guide rail mounting plate 30. As an example, referring to FIG. 3 , the guide rail 40 and the guide rail mounting plate 30 may be connected by bolts.

[0049] Moreover, in the embodiment of the present application, along the first direction X, the projection of the guide rail 40 is located in the overlapping part of the projection of the first cavity 50 and the projection of the second cavity 70, that is, the first cavity 50 and the second cavity 70 can jointly protect the guide rail 40, thereby making the guide rail 40 less likely to be deformed and damaged under impact.

[0050] Optionally, the upper side beam inner plate 10, the upper side beam reinforcement plate 20, the guide rail mounting plate 30 and the side panel outer plate 60 can all be made of high-strength steel such as Q390 steel, Q420 steel, Q460 steel, Q550 steel or Q690 steel to further improve the overall structural strength of the upper side beam structure 100.

[0051] In the above technical solution, on the one hand, the projection of the first cavity 50 and the projection of the second cavity 70 along the first direction X at least partially overlap. This superposition of the first cavity 50 and the second cavity 70 increases the cross-sectional area of ​​the energy-absorbing cavity of the roof rail structure 100, enabling the roof rail structure 100 to withstand greater impact loads and effectively improving the structural strength of the roof rail structure 100. On the other hand, along the first direction X, the projection of the first cavity 50 and the projection of the second cavity 70 at least partially overlap, and the projection of the guide rail 40 is located within the overlapping portion of the projection of the first cavity 50 and the projection of the second cavity 70. This allows the first cavity 50 and the second cavity 70 to jointly protect the guide rail 40, making it less susceptible to deformation and damage under impact. In this way, the reliability of the vehicle is effectively improved.

[0052] In some embodiments, a dimension h1 of the first cavity 50 along the first direction X satisfies: h1≥45 mm, a dimension h2 of the first cavity 50 along the second direction Y satisfies: h2≥10 mm, and the second direction Y is perpendicular to the first direction X.

[0053] As described above, the upper side beam structure 100 in the embodiment of the present application can be a side beam structure on the top of the vehicle. The first direction X can be understood as the height direction of the vehicle, and the second direction Y is perpendicular to the first direction X, that is, the second direction Y can be understood as the width direction of the vehicle.

[0054] In the above embodiments, the dimension h1 of the first cavity 50 along the first direction X can be understood as the height of the first cavity 50 , and the dimension h2 of the first cavity 50 along the second direction Y can be understood as the thickness of the first cavity 50 .

[0055] The size h1 of the first cavity 50 is set within the above range, which can provide a larger height for the first cavity 50 to enhance the bearing capacity of the first cavity 50 along the first direction X, thereby further improving the structural strength of the roof rail.

[0056] The size h2 of the second cavity 70 is set within the above range, which can provide a larger width for the first cavity 50 to enhance the bearing capacity of the first cavity 50 along the second direction Y, thereby further improving the structural strength of the roof rail.

[0057] For example, the size h1 of the first cavity 50 may be, but is not limited to, 45 mm, 50 mm, 70 mm, or 90 mm. The size h2 of the first cavity 50 may be, but is not limited to, 10 mm, 15 mm, 20 mm, or 40 mm.

[0058] In some embodiments, the upper side beam structure 100 also includes an installation area 301 for installing the guide rail 40. The installation area 301 is located on the side of the guide rail mounting plate 30 away from the first cavity 50. The cross-sectional area of ​​the first cavity 50 along the first direction X is greater than the cross-sectional area of ​​the installation area 301 along the first direction X.

[0059] For example, the installation area 301 can be understood as a portion of the space in the roof rail structure 100 occupied by the guide rail 40. It is understandable that the larger the cross-sectional area of ​​the installation area 301 along the first direction X, the larger the space in the roof rail structure 100 occupied by the guide rail 40, thereby reducing the space for the first cavity 50. Similarly, the smaller the cross-sectional area of ​​the installation area 301 along the first direction X, the smaller the space in the roof rail structure 100 occupied by the guide rail 40, thereby increasing the space for the first cavity 50.

[0060] In the above technical solution, by setting the cross-sectional area of ​​the first cavity 50 along the first direction X to be larger than the cross-sectional area of ​​the installation area 301 along the first direction X, the space occupied by the installation area 301 in the upper side beam structure 100 can be reduced, thereby increasing the setting space of the first cavity 50, further improving the bearing capacity of the first cavity 50, and further improving the structural strength of the upper side beam.

[0061] In some embodiments, the roof rail inner plate 10 , the roof rail reinforcement plate 20 , the guide rail mounting plate 30 and the side panel outer plate 60 are an integrally formed structure.

[0062] For example, the roof rail inner panel 10, the roof rail reinforcement panel 20, the guide rail mounting plate 30, and the side panel outer panel 60 can be integrally formed through a roll-forming process. This eliminates the need for an additional connection process to connect the roof rail inner panel 10, the roof rail reinforcement panel 20, the guide rail mounting plate 30, and the side panel outer panel 60, thereby simplifying the manufacturing process of the roof rail structure 100. Furthermore, compared to connecting the roof rail inner panel 10, the roof rail reinforcement panel 20, the guide rail mounting plate 30, and the side panel outer panel 60 through an additional connection process, the integral structure of the roof rail inner panel 10, the roof rail reinforcement panel 20, the guide rail mounting plate 30, and the side panel outer panel 60 has a higher connection strength, further improving the overall structural strength of the roof rail structure 100 and further enhancing the reliability of the vehicle.

[0063] In some embodiments, the first connection portion 80 of the side outer panel 60 and the upper side beam reinforcement plate 20 extends along the first direction X, and the projection of the first connection portion 80 along the second direction Y covers at least part of the projection of the guide rail 40 along the second direction Y.

[0064] The first connection portion 80 between the side panel 60 and the roof rail reinforcement 20 is the connection point close to the guide rail 40. The first connection portion 80 extends along the first direction X. As mentioned above, the first direction X can be understood as the height direction of the vehicle, and the second direction Y can be understood as the width direction of the vehicle.

[0065] It is understandable that the guide rail 40 is used to install the sliding door of the vehicle, so that the sliding door can slide. In the embodiment of the present application, the extension direction of the upper side beam structure 100 and the various panels in the upper side beam structure 100 and the guide rail 40 is the longitudinal direction of the vehicle. The projection of the first connecting portion 80 along the second direction Y covers at least part of the projection of the guide rail 40 along the second direction Y, that is, along the second direction Y, the first connecting portion 80 can block at least part of the guide rail 40. For example, along the second direction Y, the first connecting portion 80 can block a portion of the guide rail 40, or it can block the entire guide rail.

[0066] In the above technical solution, the first connecting portion 80 of the side outer panel 60 and the upper side beam reinforcement plate 20 is extended along the first direction X, and the first connecting portion 80 along the second direction Y can block at least part of the guide rail 40. On the one hand, the first connecting portion 80 blocks the guide rail 40 so that the guide rail 40 will not be exposed to the user's field of vision, which can improve the aesthetics of the vehicle; on the other hand, the first connecting portion 80 blocks the guide rail 40 and can also protect the guide rail 40, which can reduce the occurrence of objects in the external environment hitting the guide rail 40 and causing damage to the sliding door, thereby improving the reliability of the guide rail 40.

[0067] In some embodiments, along the second direction Y, the projection of the guide rail 40 is located within the projection of the first connecting portion 80, so that the first connecting portion 80 can completely cover the guide rail 40 along the second direction Y, further improving the aesthetics of the vehicle and the reliability of the slide rail.

[0068] In some embodiments, reinforcing ribs are provided on at least one of the roof side rail inner panel 10 , the roof side rail reinforcement panel 20 , the guide rail mounting plate 30 , or the side panel outer panel 60 .

[0069] The reinforcing ribs can improve the structural strength of the roof side rail inner panel 10, the roof side rail reinforcement panel 20, the guide rail mounting plate 30, or the side panel outer panel 60. For example, the reinforcing ribs can protrude from the side surface of the roof side rail inner panel 10, the roof side rail reinforcement panel 20, the guide rail mounting plate 30, or the side panel outer panel 60 that is close to the first cavity 50, or can protrude from the side surface of the roof side rail inner panel 10, the roof side rail reinforcement panel 20, the guide rail mounting plate 30, or the side panel outer panel 60 that is away from the first cavity 50.

[0070] In some optional embodiments, the reinforcing ribs are integrally formed with the upper side beam inner plate 10, the upper side beam reinforcement plate 20, the guide rail mounting plate 30 or the side panel outer plate 60, that is, the reinforcing ribs can be integrally formed by a stamping process, the manufacturing process is simple and no additional materials are required.

[0071] In the above technical solution, by arranging reinforcing ribs on at least one of the upper side beam inner plate 10, the upper side beam reinforcement plate 20, the guide rail mounting plate 30 or the side panel outer plate 60, the reinforcing ribs can reduce the deformation of the upper side beam inner plate 10, the upper side beam reinforcement plate 20, the guide rail mounting plate 30 or the side panel outer plate 60, and improve the compressive strength of the upper side beam inner plate 10, the upper side beam reinforcement plate 20, the guide rail mounting plate 30 or the side panel outer plate 60, thereby further improving the structural strength of the upper side beam.

[0072] In some embodiments, the guide rail mounting plate 30 includes a first mounting plate 31 and a second mounting plate 32 . The roof rail reinforcement plate 20 , the first mounting plate 31 , the second mounting plate 32 and the roof rail inner plate 10 are connected end to end to form a first cavity 50 .

[0073] Exemplarily, the guide rail mounting plate 30 includes a first mounting plate 31 and a second mounting plate 32 that are independently connected to each other. One end of the roof rail inner plate 10 is connected to one end of the roof rail reinforcement plate 20, the other end of the roof rail inner plate 10 is connected to one end of the first mounting plate 31, the other end of the first mounting plate 31 is connected to one end of the second mounting plate 32, and the other end of the second mounting plate 32 is connected to the other end of the roof rail reinforcement plate 20. In this way, the roof rail reinforcement plate 20, the first mounting plate 31, the second mounting plate 32 and the roof rail inner plate 10 are connected end to end, and a first cavity 50 is formed inside the roof rail reinforcement plate 20, the first mounting plate 31, the second mounting plate 32 and the roof rail inner plate 10.

[0074] It should be noted that the roof rail reinforcement plate 20, the first mounting plate 31, the second mounting plate 32, and the roof rail inner plate 10 can be connected end to end in a clockwise direction or in a counterclockwise direction. The first mounting plate 31 and the second mounting plate 32 are both curved plates in an irregularly bent state. This application does not limit the specific structural shape of the first mounting plate 31 and the second mounting plate 32, and they can be set according to actual circumstances.

[0075] In the above technical solution, by setting the guide rail mounting plate 30 as a first mounting plate 31 and a second mounting plate 32 that are independently connected to each other, the boundary shape of the upper side beam structure 100 can be arranged more flexibly, so that the upper side beam structure 100 can adapt to more structural shape arrangements, thereby improving the flexibility of use of the upper side beam structure 100.

[0076] In some embodiments, a support plate 90 is provided inside the first cavity 50, and the support plate 90 is connected between the inner walls of the first cavity 50 along the first direction X, and / or, the support plate 90 is connected between the inner walls of the first cavity 50 along the second direction Y.

[0077] The support plate 90 can provide support between the inner walls of the first cavity 50. For example, the support plate 90 can be connected between the inner walls of the first cavity 50 along the first direction X, or can be connected between the inner walls of the first cavity 50 along the second direction Y, or can be connected to both the inner walls of the first cavity 50 along the first direction X and the inner walls of the first cavity 50 along the second direction Y. When the support plate 90 is connected between the inner walls of the first cavity 50 along the first direction X, the support plate 90 supports the inner walls of the first cavity 50 along the first direction X, and the support plate 90 can provide support between the inner walls of the first cavity 50 along the first direction X; when the support plate 90 is connected between the inner walls of the first cavity 50 along the second direction Y, the support plate 90 supports the inner walls of the first cavity 50 along the second direction Y, and the support plate 90 can provide support between the inner walls of the first cavity 50 along the second direction Y.

[0078] Optionally, the support plate 90 may be made of, but not limited to, a metal material such as stainless steel, aluminum, or titanium, etc. The support plate 90 may be connected to the inner wall of the first cavity 50 by, but not limited to, welding, riveting, or bolting.

[0079] In the above technical solution, by setting a support plate 90 between the inner walls of the first cavity 50, the support plate 90 can provide support force between the inner walls of the first cavity 50, thereby further improving the bearing capacity of the first cavity 50 and further improving the structural strength of the upper side beam.
