[0032] With the rapid development of economy and automobile industry, people have higher and higher requirements on the appearance and comfort of automobiles. Therefore, B-pillar-free models are becoming more and more popular. For vehicles, B-pillar is an important component to improve vehicle safety. When the vehicle rolls or overturns, B-pillar can effectively prevent the cockpit from being squeezed and deformed, and play a protective role for the passengers in the vehicle.

[0033] The inventor of the present application has noticed that due to the elimination of the B-pillar structure, the upper side beam structure of the vehicle needs to bear a greater load. Currently, most B-pillar-free models are equipped with sliding doors. The layout requirements of the upper guide rails of the sliding doors will result in the upper side beam structure not having enough cavity space to provide support force, resulting in a lower structural strength of the upper side beam structure, and thus lower vehicle safety.

[0034] The inventors of the present 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 provided 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.

[0035] In order to solve the problems of the prior art, an 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 in the embodiment of the present application is first introduced below.

[0036] Figure 1 A schematic diagram of a top beam structure provided in some embodiments of the present application; Figure 2 A schematic diagram of a cross-sectional structure of an upper side beam structure along AA provided in some embodiments of the present application;

[0037] Figure 3 A schematic cross-sectional structure diagram of a connection method between a guide rail and a guide rail mounting plate in an upper side beam structure provided in some embodiments of the present application.

[0038] like Figures 1 to 3 As shown, the 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 disposed 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 the 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.

[0039] In the embodiment of the present application, the upper side beam structure 100 may be a side beam structure on the top of the vehicle, and the first direction X may be understood as the height direction of the vehicle.

[0040] Exemplarily, one end of the upper side beam inner plate 10 is connected to one end of the upper side beam reinforcement plate 20, the other end of the upper side beam inner plate 10 is connected to one end of the guide rail mounting plate 30, and the other end of the upper side beam reinforcement plate 20 is connected to the other end of the guide rail mounting plate 30, so that the upper side beam inner plate 10, the upper side beam reinforcement plate 20 and the guide rail mounting plate 30 are connected end to end, and a first cavity 50 is formed inside the upper side beam inner plate 10, the upper side beam reinforcement plate 20 and the guide rail mounting plate 30. The first cavity 50 is the main bearing cavity of the upper side beam structure 100, and the larger the cavity space of the first cavity 50, the greater the load that can be borne.

[0041] It should be noted that the upper side beam inner plate 10, the upper side beam reinforcement plate 20 and the guide rail mounting plate 30 can be connected end to end in a clockwise direction or end to end in a counterclockwise direction. The upper side beam inner plate 10, the upper side beam reinforcement plate 20 and the guide rail mounting plate 30 are all curved plates in an irregular bending state. The present application does not limit the specific structural shape and connection sequence of the upper side beam inner plate 10, the upper side beam reinforcement plate 20 and the guide rail mounting plate 30, which can be set according to actual conditions.

[0042] Optionally, the upper side beam inner plate 10, the upper side beam reinforcement plate 20, the guide rail mounting plate 30 and the guide rail 40 can all be made of metal materials, such as stainless steel, aluminum or titanium. The connection method between the upper side beam inner plate 10, the upper side beam reinforcement plate 20, the guide rail mounting plate 30 and the guide rail 40 can be but is not limited to welding, riveting or bolting.

[0043] 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.

[0044] As mentioned above, one end of the upper side beam reinforcement plate 20 is also connected to the upper side beam inner plate 10. At the connection of one end where the upper side beam reinforcement plate 20 is connected to the upper side beam inner plate 10, the side outer plate 60, the upper side beam reinforcement plate 20 and the upper side beam inner plate 10 form a sandwich structure in which the upper side beam reinforcement plate 20 is located in the middle, and the side outer plate 60 and the upper side beam inner plate 10 are located on both sides of the upper side beam reinforcement plate 20 along the thickness direction of itself; similarly, the other end of the upper side beam reinforcement plate 20 is also connected to the guide rail mounting plate 30, and at the connection of one end where the upper side beam reinforcement plate 20 is connected to the guide rail mounting plate 30, the side outer plate 60, the upper side beam reinforcement plate 20 and the upper side beam inner plate 10 form a sandwich structure in which the upper side beam reinforcement plate 20 is located in the middle, and the side outer plate 60 and the guide rail mounting plate 30 are located on both sides of the upper side beam reinforcement plate 20 along the thickness direction of itself. The above arrangement can improve the structural strength of the connection between the side panel outer plate 60 , the roof side beam reinforcement plate 20 , the roof side beam inner plate 10 and the guide rail mounting plate 30 , thereby improving the overall reliability of the roof side beam structure 100 .

[0045] 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 bearing capacity. The larger the cavity space of the second cavity 70, the greater the load that the second cavity 70 can bear. At the same time, the second cavity 70 can also improve the bending and torsional strength of the upper side rail structure 100.

[0046] Optionally, the side panel 60 may be made of a metal material, such as stainless steel, aluminum or titanium. The side panel 60 is a curved panel in an irregular bending state. The connection between the side panel 60 and the upper side beam reinforcement plate 20, and the connection between the guide rail mounting plate 30 and the guide rail 40 may be, but not limited to, welding, riveting or bolting.

[0047] The guide rail 40 is installed on the guide rail mounting plate 30. The guide rail 40 will occupy a part of the space in the upper side beam structure 100, and thus will cause a certain restriction on the setting space of 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 away from the second cavity 70 along the first direction X, that is, the guide rail 40 is arranged away from the upper side beam reinforcement plate 20 along the first direction X, that is, the upper side beam reinforcement plate 20 and the guide rail 40 are located on both sides of the first cavity 50 along the first direction X, so that there is a certain space between the guide rail 40 and the upper side beam reinforcement plate 20, and thus the first cavity 50 has a larger size in the first direction X. It should be noted that in the embodiment of the present application, after the upper side beam inner plate 10, the upper side beam reinforcement plate 20 and the guide rail mounting plate 30 are connected, the guide rail 40 is installed on the guide rail mounting plate 30, which can avoid the connection difficulty caused by the guide rail 40 blocking the connection between the upper side beam reinforcement plate 20 and the guide rail mounting plate 30. As an example, refer to Figure 3The guide rail 40 and the guide rail mounting plate 30 may be connected by bolts.

[0048] 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.

[0049] 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.

[0050] In the above technical solution, on the one 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, so that the cross-sectional area of ​​the energy-absorbing cavity of the upper side beam structure 100 as a whole is increased by the superposition of the first cavity 50 and the second cavity 70, so that the upper side beam structure 100 can withstand a larger impact load, and the structural strength of the upper side beam structure 100 is effectively improved; 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 in the overlapping part of the projection of the first cavity 50 and the projection of the second cavity 70, so that the first cavity 50 and the second cavity 70 can jointly protect the guide rail 40, so that the guide rail 40 is less likely to be deformed and damaged under impact. In this way, the reliability of the vehicle is effectively improved.

[0051] In some embodiments, the dimension h1 of the first cavity 50 along the first direction X satisfies:

[0052] 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, and the installation area 301 is located on the side of the guide rail mounting plate 30 away from the first cavity 50, and the cross-sectional area of ​​the first cavity 50 along the first direction X is larger than the cross-sectional area of ​​the installation area 301 along the first direction X.

[0059] Exemplarily, the installation area 301 can be understood as a portion of the space in the upper side beam structure 100 occupied by the guide rail 40. It can be understood that the larger the cross-sectional area of ​​the installation area 301 along the first direction X, the larger the space in the upper side beam structure 100 occupied by the guide rail 40, and thus the smaller the setting space of 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 upper side beam structure 100 occupied by the guide rail 40, and thus the larger the setting space of 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 upper side beam inner plate 10, the upper side beam reinforcement plate 20, the guide rail mounting plate 30 and the side outer plate 60 can be integrally formed by a rolling process. On the one hand, there is no need to connect the upper side beam inner plate 10, the upper side beam reinforcement plate 20, the guide rail mounting plate 30 and the side outer plate 60 through an additional connection process, which simplifies the manufacturing process of the upper side beam structure 100. At the same time, compared with connecting the upper side beam inner plate 10, the upper side beam reinforcement plate 20, the guide rail mounting plate 30 and the side outer plate 60 through an additional connection process, the upper side beam inner plate 10, the upper side beam reinforcement plate 20, the guide rail mounting plate 30 and the side outer plate 60 in an integrated structure have a higher connection firmness, which can further improve the overall structural strength of the upper side beam structure 100 and further improve 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 beam reinforcement plate 20 is a connection portion 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 length 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. Exemplarily, 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 slide rail.

[0066] In the above technical solution, the first connection portion 80 between the side outer panel 60 and the upper side beam reinforcement plate 20 is extended along the first direction X, and the first connection portion 80 along the second direction Y can block at least a portion of the guide rail 40. On the one hand, the first connection 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 connection portion 80 blocks the guide rail 40 and protects 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 rail inner plate 10 , the roof rail reinforcement plate 20 , the guide rail mounting plate 30 , or the side panel outer plate 60 .

[0069] The reinforcing ribs can improve the structural strength of the roof side beam inner plate 10, the roof side beam reinforcement plate 20, the guide rail mounting plate 30 or the side outer plate 60. For example, the reinforcing ribs can protrude from the side surface of the roof side beam inner plate 10, the roof side beam reinforcement plate 20, the guide rail mounting plate 30 or the side outer plate 60 close to the first cavity 50, or protrude from the side surface of the roof side beam inner plate 10, the roof side beam reinforcement plate 20, the guide rail mounting plate 30 or the side outer plate 60 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, and the manufacturing process is simple and does not require the addition of other materials.

[0071] In the above technical scheme, 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 , and 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 which are independently connected to each other. One end of the upper side beam inner plate 10 is connected to one end of the upper side beam reinforcement plate 20, the other end of the upper side beam 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 upper side beam reinforcement plate 20, so that the upper side beam reinforcement plate 20, the first mounting plate 31, the second mounting plate 32 and the upper side beam inner plate 10 are connected end to end, and a first cavity 50 is formed inside the upper side beam reinforcement plate 20, the first mounting plate 31, the second mounting plate 32 and the upper side beam inner plate 10.

[0074] It should be noted that the upper side beam reinforcement plate 20, the first mounting plate 31, the second mounting plate 32 and the upper side beam 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 irregular bending state. The specific structural shape sequence of the first mounting plate 31 and the second mounting plate 32 is not limited in this application and can be set according to actual conditions.

[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 use flexibility of the upper side beam structure 100.

[0076] In some embodiments, a support plate 90 is disposed 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 force between the inner walls of the first cavity 50. Exemplarily, the support plate 90 can be connected between the inner walls of the first cavity 50 along the first direction X, can be connected between the inner walls of the first cavity 50 along the second direction Y, or can be connected between 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 force 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 force between the inner walls of the first cavity 50 along the second direction Y.

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

[0079] In the above technical solution, by setting the 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.
