Description

Technical Field

[0001] This utility model belongs to the field of vehicle body assembly technology, specifically relating to a vehicle body structure and vehicle. Background Technology

[0002] The side skirts, as an important part of the car body, are a type of body kit. Located on the sides of the car body, they typically cover the doors, side windows, windshields, and other side cladding. They not only provide protection against wind, rain, and noise, but also offer additional protection in the event of a collision.

[0003] The existing vehicle body side panels have insufficient torsional stiffness and roof crush resistance, which directly affects the torsional stiffness and roof crush resistance of the entire vehicle, and thus affects the overall driving and riding safety. Utility Model Content

[0004] This utility model provides a vehicle body structure and vehicle, which aims to solve the problem of insufficient torsional stiffness and top pressure resistance of existing vehicle body side panels.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] In a first aspect, embodiments of the present invention provide a vehicle body structure, including:

[0007] The rear section assembly of the inner side panel and the side panel reinforcing plate assembly are provided, wherein the front part of the rear section assembly of the inner side panel is connected to the rear part of the side panel reinforcing plate assembly to form the inner side panel assembly.

[0008] Specifically, the upper beam reinforcing plate in the side panel reinforcing plate assembly overlaps and is fixedly attached to the C-pillar reinforcing plate in the rear section assembly of the inner side panel, and the sill beam reinforcing plate in the side panel reinforcing plate assembly overlaps and is fixedly attached to the lower section of the C-pillar reinforcing plate in the rear section assembly of the inner side panel.

[0009] The existing body assembly method is as follows: First, the rear section of the inner panel assembly and the front section of the side inner panel assembly are assembled into one unit to form the side inner panel assembly. Simultaneously, the side reinforcement plate assembly and the side outer panel sub-assembly are assembled to form the side outer panel assembly. Then, the side inner panel assembly and the side outer panel assembly are assembled to form the side panel assembly. Finally, the side panel assembly is assembled with the lower body assembly to form the body structure. During the welding of the side inner panel assembly and the side outer panel assembly, the side outer panel sub-assembly obstructs the welding, creating gaps between the upper edge beam reinforcement plate in the side reinforcement plate assembly and the upper end of the C-pillar reinforcement plate in the rear section of the side inner panel assembly. Similarly, gaps are formed in the overlap area between the lower section of the C-pillar reinforcement plate in the rear section of the side inner panel assembly and the sill beam reinforcement plate in the side reinforcement plate assembly. This results in gaps at the front and rear ends of the sheet metal structure in the corresponding area of ​​the C-pillar, causing these suspended areas to directly affect the torsional stiffness and roof crush resistance of the side panel. Compared with the prior art, the solution shown in this application pre-assembles the rear section assembly of the inner side panel and the side panel reinforcement assembly to form the inner side panel assembly. At this time, without the obstruction of the outer side panel sub-assembly, the upper beam reinforcement plate in the side panel reinforcement assembly and the C-pillar reinforcement plate in the rear section assembly of the inner side panel can overlap and fit together, and the sill beam reinforcement plate in the side panel reinforcement assembly and the lower section of the C-pillar reinforcement plate in the rear section assembly of the inner side panel can overlap and fit together, so that the sheet metal at the upper and lower ends of the corresponding area of ​​the C-pillar can be effectively connected and fixed, which can improve the torsional stiffness and anti-top pressure performance of the side panel area, thereby improving the torsional stiffness and anti-top pressure performance of the whole vehicle.

[0010] In conjunction with the first aspect, in one possible implementation, the arched portion of the upper beam reinforcing plate and the arched portion of the C-column reinforcing plate are fitted together, and there are multiple first connection positions distributed along the front-rear direction between them. By setting multiple first connection positions, the bonding strength between the upper beam reinforcing plate and the C-column reinforcing plate is enhanced. At the same time, the front-rear distribution effectively reduces the space occupied in the vertical direction, thus completing the connection and fixation between the upper beam reinforcing plate and the C-column reinforcing plate.

[0011] In some embodiments, the upper beam reinforcing plate has upper beam connecting flanges on its front and rear sides at its lower end, and the C-column reinforcing plate has C-column connecting flanges on its front and rear sides at its upper end. The upper beam connecting flanges are respectively fitted and connected to the corresponding C-column connecting flanges, and there is a second connection point between the upper beam connecting flange and the corresponding C-column connecting flange. The upper beam connecting flange and the C-column connecting flange not only strengthen the structure but also increase the bonding area between the upper beam reinforcing plate and the C-column reinforcing plate. By adding a second connection point, the number of connection points between the upper beam reinforcing plate and the C-column reinforcing plate is further increased, thereby further enhancing the bonding strength between them.

[0012] In conjunction with the first aspect, in one possible implementation, the lower end of the lower section of the C-pillar reinforcing plate is provided with a lower section connecting edge, the lower section connecting edge having two lower section mating walls set at an angle; the rear end of the sill beam reinforcing plate is provided with a sill connecting edge, the sill connecting edge having two sill mating walls set at an angle.

[0013] The two lower fitting walls are respectively fitted and connected to the corresponding threshold fitting wall, and there is a third connection position between the lower fitting wall and the corresponding threshold fitting wall.

[0014] By setting a third connection point with different bonding directions, the multi-directional load-bearing capacity of the bonding area between the lower section of the C-pillar reinforcement plate and the sill beam reinforcement plate can be significantly improved, which is conducive to improving the bonding strength between the two and thus improving the ability to resist lateral impact.

[0015] In conjunction with the first aspect, in one possible implementation, the vehicle body structure further includes a front section assembly of the side inner panel and a lower body assembly, wherein the lower part of the front section assembly of the side inner panel is connected to the side of the lower body assembly to form the lower body assembly;

[0016] The side inner panel assembly is connected to the outside of the lower body assembly, wherein the rear end of the middle section of the upper side beam inner panel in the front section of the side inner panel assembly overlaps and is fixed to the upper end of the C-pillar inner panel in the rear section of the side inner panel assembly.

[0017] The front section of the side inner panel assembly is connected to the lower body assembly to form the lower body assembly. This lower body assembly is then connected to the aforementioned side inner panel assembly to reduce the number of parts being added and improve assembly efficiency. In order not to affect the connection of the upper side beam area, the rear end of the middle section of the upper side beam inner panel in the front section of the side inner panel assembly is overlapped and fixed to the upper end of the C-pillar inner panel in the rear section of the side inner panel assembly.

[0018] In some embodiments, a first overlapping platform is formed at the rear of the middle section of the upper side beam inner panel, and a second overlapping platform is formed at the upper end of the C-pillar inner panel. The first overlapping platform and the second overlapping platform are in close contact. A first mounting hole is provided on the first overlapping platform, and a second mounting hole is provided on the second overlapping platform. The first overlapping platform and the second overlapping platform are fixed by fasteners passing through the first mounting hole and the second mounting hole. Taking into full account the gap generated between the side panel assembly and the lower body assembly in the upper side beam area, the connection is achieved by overlapping and fixing with fasteners, resulting in good connection reliability.

[0019] In some embodiments, multiple first mounting holes and multiple second mounting holes are provided along the vertical direction, each corresponding to one of the first mounting holes. This fully utilizes the space of the first and second overlapping platforms, increasing the number of connection points and enhancing the bonding strength between them.

[0020] In conjunction with the first aspect, in one possible implementation, in order to maintain the integrity of the vehicle body structure, the vehicle body structure further includes a side outer panel assembly connected to the outside of the side inner panel assembly.

[0021] In some embodiments, the vehicle body structure further includes a front section assembly of the side inner panel and a lower body assembly, wherein the lower part of the front section assembly of the side inner panel is connected to the side of the lower body assembly to form the lower body assembly;

[0022] The side panel assembly is a frame formed by connecting the outer side panel assembly and the inner side panel assembly. The side panel assembly is connected to the outside of the lower body assembly.

[0023] By adjusting the welding sequence between various assemblies, the problem of the inability to connect the sheet metal at the upper and lower ends of the C-pillar is avoided. At the same time, it can also ensure that the rear end of the middle section of the upper side beam inner panel in the front section of the side inner panel assembly can be overlapped and fixed with the upper end of the C-pillar inner panel in the rear section of the side inner panel assembly. The overall integrity of the body structure is stronger, which plays a positive role in improving the torsional stiffness and top pressure resistance of the body structure itself.

[0024] Secondly, this utility model embodiment also provides a vehicle including the above-described body structure.

[0025] Compared with the prior art, the solution shown in this application improves the torsional stiffness and top pressure resistance of the vehicle by adopting the above-mentioned body structure, thereby optimizing the driving safety of the vehicle and enhancing the market competitiveness of the product.

[0042] Please refer to the following: Figure 1 , Figures 4 to 6 The vehicle body structure 1 provided by this utility model will now be described. The vehicle body structure 1 includes a rear section assembly 100 of the inner side panel and a side reinforcement plate assembly 200. The front part of the rear section assembly 100 of the inner side panel is connected to the rear part of the side reinforcement plate assembly 200 to form the inner side panel assembly 10. The upper beam reinforcement plate 210 in the side reinforcement plate assembly 200 overlaps and is fixedly attached to the C-pillar reinforcement plate 110 in the rear section assembly 100 of the inner side panel, and the sill beam reinforcement plate 220 in the side reinforcement plate assembly 200 overlaps and is fixedly attached to the lower section 120 of the C-pillar reinforcement plate in the rear section assembly 100 of the inner side panel.

[0043] This embodiment exemplarily illustrates the assembly structure of the rear section assembly 100 of the left side inner panel and the side reinforcement plate assembly 200. The structures on the left and right sides of the vehicle body are symmetrical, and the structure on the right side will not be described in detail here.

[0044] The existing body assembly method is as follows: First, the rear section assembly of the inner panel is assembled with the front section assembly of the side inner panel to form the side inner panel assembly. At the same time, the side reinforcement plate assembly is assembled with the side outer panel sub-assembly to form the side outer panel assembly. Then, the side inner panel assembly and the side outer panel assembly are assembled to form the side assembly. Finally, the side assembly is assembled with the lower body assembly to form the body structure. When the inner side panel assembly and the outer side panel assembly are welded together, the outer side panel sub-assembly obstructs the connection between the upper beam reinforcement plate in the side panel reinforcement plate assembly and the upper end of the C-pillar reinforcement plate in the rear section of the inner side panel assembly. The lower section of the C-pillar reinforcement plate in the rear section of the inner side panel assembly and the sill beam reinforcement plate in the side panel reinforcement plate assembly also form gaps at intervals. This results in the problem that the upper and lower ends of the corresponding area of ​​the C-pillar cannot be connected by sheet metal structures. These suspended areas directly affect the torsional stiffness and top pressure resistance of the side panel.

[0045] Compared with the prior art, the vehicle body structure 1 provided in this embodiment pre-assembles the rear section assembly 100 of the inner side panel and the side reinforcement plate assembly 200 to form the inner side panel assembly 10. At this time, without the obstruction of the outer side panel sub-assembly, the upper beam reinforcement plate 210 in the side reinforcement plate assembly 200 and the C-pillar reinforcement plate 110 in the rear section assembly 100 of the inner side panel can overlap and fit together and be fixed. In addition, the sill beam reinforcement plate 220 in the side reinforcement plate assembly 200 and the lower section 120 of the C-pillar reinforcement plate in the rear section assembly 100 of the inner side panel can overlap and fit together and be fixed. This allows the upper and lower sheet metal of the corresponding area of ​​the C-pillar to be effectively connected and fixed, which can improve the torsional stiffness and anti-top pressure performance of the side area, thereby improving the torsional stiffness and anti-top pressure performance of the whole vehicle.

[0046] Considering that the area where the column is located is a key area requiring reinforcement, in order to maintain the structural strength of the C-column, the area where the upper beam reinforcing plate 210 connects with the C-column reinforcing plate 110, and the C-column reinforcing plate 110 itself, are both inwardly arched plates. Therefore, to achieve a lapped and fixed fit between the arched portion of the upper beam reinforcing plate 210 and the C-column reinforcing plate 110, in some embodiments, see... Figure 5 The arched portion of the upper beam reinforcing plate 210 is fitted and connected to the arched portion of the C-column reinforcing plate 110, and the two have multiple first connection positions 20 distributed along the front-back direction. These first connection positions 20 are welded connections. By setting multiple first connection positions 20, the bonding strength between the upper beam reinforcing plate 210 and the C-column reinforcing plate 110 is enhanced. Simultaneously, the front-back distribution effectively reduces the vertical space occupied, fully adapting to situations where the overlap area between the upper beam reinforcing plate 210 and the C-column reinforcing plate 110 is narrow, thus completing the connection and fixation between the upper beam reinforcing plate 210 and the C-column reinforcing plate 110.

[0047] Optionally, both the arched portion of the upper side beam reinforcement plate 210 and the arched portion of the C-column reinforcement plate 110 have an inner wall and two side walls respectively provided on the front and rear sides of the inner wall. The inner wall and the two side walls form an arched shape. To reduce the difficulty of welding operations, a plurality of first connection positions 20 are arranged corresponding to the inner walls of the arched portions of the upper side beam reinforcement plate 210 and the C-column reinforcement plate 110, so as to obtain a larger operating space.

[0048] During specific implementation, there are two first connection positions 20, which are arranged approximately evenly on the inner wall of the arched portion. In this way, the number of first connection positions 20 is reduced, the adverse effects of welding on the sheet metal parts are avoided, and at the same time, the assembly progress can be accelerated.

[0049] In some embodiments, referring to Figure 5 , on the front side and the rear side of the lower end of the upper side beam reinforcement plate 210, upper side beam connection flanges 211 are respectively provided, and on the front side and the rear side of the upper end of the C-column reinforcement plate 110, C-column connection flanges 111 are respectively provided. By providing the upper side beam connection flanges 211 and the C-column connection flanges 111, and combining the arched design of the upper side beam reinforcement plate 210 and the C-column reinforcement plate 110 described above, the cross-sections of the upper side beam reinforcement plate 210 and the C-column reinforcement plate 110 are in a "C" shape, which is beneficial to further enhancing the structural strength of the upper side beam reinforcement plate 210 and the C-column reinforcement plate 110. Based on this, the upper side beam connection flanges 211 are respectively in close connection with the corresponding C-column connection flanges 111, and there is a second connection position 30 between the upper side beam connection flanges 211 and the corresponding C-column connection flanges 111. In this way, the upper side beam connection flanges 211 and the C-column connection flanges 111 can not only play a role in strengthening the structure, but also increase the bonding area between the upper side beam reinforcement plate 210 and the C-column reinforcement plate 110. By adding a second connection position 30, the number of connection points between the upper side beam reinforcement plate 210 and the C-column reinforcement plate 110 is further increased, and thus the bonding strength between the upper side beam reinforcement plate 210 and the C-column reinforcement plate 110 is further enhanced.

[0050] Optionally, in order to make full use of the limited overlapping space between the upper side beam reinforcement plate 210 and the C-column reinforcement plate 110, the heights of the first connection position 20 and the second connection position 30 are approximately the same. In addition, since the widths of the upper side beam connection flanges 211 and the C-column connection flanges 111 are limited, in order to make full use of the limited space and ensure the bonding strength, a second connection position 30 is provided at the upper side beam connection flanges 211 and the C-column connection flanges 111 at the front part, and a second connection position 30 is provided at the upper side beam connection flanges 211 and the C-column connection flanges 111 at the rear part.

[0051] In some embodiments, referring to Figure 6The lower end of the lower section 120 of the C-pillar reinforcement plate is provided with a lower section connecting edge 121, and the lower section connecting edge 121 has two lower section fitting walls 1211 set at an included angle; the rear end of the sill beam reinforcement plate 220 is provided with a sill connecting edge 221, and the sill connecting edge 221 has two sill fitting walls 2211 set at an included angle; the two lower section fitting walls 1211 are respectively fitted and connected to the corresponding sill fitting walls 2211, and there is a third connection position 40 between the lower section fitting wall 1211 and the corresponding sill fitting wall 2211. In this embodiment, the two lower section fitting walls 1211 form a connection part with a cross section that is approximately "L" shaped, and the two sill fitting walls 2211 also form a connection part with a cross section that is approximately "L" shaped, in order to adapt to the structural design requirements of the lower sill area. Based on this, a third connection position 40 is provided on different fitting walls. Since there are many third connection positions 40, and the connection direction of the third connection positions 40 corresponding to different fitting walls is different, for example... Figure 6 In the middle, the joint direction of the upper third connection position 40 is at an angle to the joint direction of the lower third connection position 40. In this way, the multi-directional load-bearing capacity of the joint area between the lower section 120 of the C-pillar reinforcement plate and the sill beam reinforcement plate 220 can be significantly improved, which is conducive to improving the joint strength of the two and thus improving the ability to resist lateral impact.

[0052] Optionally, since the dimensions of the lower fitting wall 1211 and the threshold fitting wall 2211 are relatively small, the number of third connection positions 40 should be minimized while ensuring the bonding strength. For example, Figure 6 The diagram shows a case where a third connection position 40 is provided between the lower section fitting wall 1211 and the corresponding threshold fitting wall 2211.

[0053] In some embodiments, see Figure 2 , Figure 7 and Figure 8 The vehicle body structure 1 also includes a front section assembly of the side inner panel 300 and a lower body assembly 400. The lower part of the front section assembly of the side inner panel 300 is connected to the side of the lower body assembly 400, forming a lower body assembly 50. The side inner panel assembly 10 is connected to the outside of the lower body assembly 50. The rear end of the middle section 310 of the upper side beam inner panel in the front section assembly of the side inner panel 300 overlaps and is fixed to the upper end of the C-pillar inner panel 130 in the rear section assembly of the side inner panel 100. In this embodiment, the front section assembly of the side inner panel 300 is connected to the lower body assembly 400 to form the lower body assembly 400, which is then connected to the aforementioned side inner panel assembly 10, reducing the number of assembly steps and improving assembly efficiency. Therefore, in order not to affect the connection of the upper beam area, the rear end of the middle section 310 of the upper beam inner panel in the front section assembly 300 of the side inner panel overlaps and is fixed with the upper end of the C-column inner panel 130 in the rear section assembly 100 of the side inner panel.

[0054] Based on the above embodiments, see Figure 8 A first overlapping platform 311 is formed at the rear of the middle section 310 of the upper side beam inner panel, and a second overlapping platform 131 is formed at the upper end of the C-pillar inner panel 130. The first overlapping platform 311 and the second overlapping platform 131 are in close contact. The first overlapping platform 311 is provided with a first mounting hole 312, and the second overlapping platform 131 is provided with a second mounting hole 132. The first overlapping platform 311 and the second overlapping platform 131 are fixed by fasteners passing through the first mounting hole 312 and the second mounting hole 132. Both the first overlapping platform 311 and the second overlapping platform 131 have overlapping and contacting planes, and they can be formed in the middle section 310 of the upper side beam inner panel and the C-pillar inner panel 130 respectively by stamping. This embodiment fully considers the gap generated between the side inner panel assembly 10 and the lower body assembly 400 in the upper side beam area, and achieves connection by fastening after overlapping, resulting in good connection reliability.

[0055] Optionally, the rear part of the middle section 310 of the upper beam inner plate is stepped, and the stepped surface of the stepped area is the first overlapping platform 311; similarly, the front upper part of the C-column inner plate 130 is stepped, and the stepped surface of the stepped area is the second overlapping platform 131. By setting the stepped structure, the rear part of the middle section 310 of the upper beam inner plate and the upper part of the C-column inner plate 130 are brought as close as possible, achieving overlapping and fixing of the two without affecting the overall structure of the plates.

[0056] Optionally, the first overlapping platform 311 is located inside the second overlapping platform 131. If the fastener is a threaded fastener, a nut seat corresponding to the second mounting hole 132 is welded and fixed on the outer surface of the second overlapping platform 131 to achieve assembly with the threaded fastener. If the fastener is a straight-insertion snap fastener, there is no need to set a connecting seat on the outer side of the second overlapping platform 131. Other fastener implementation methods will not be listed here.

[0057] If the first overlapping platform 311 is located outside the second overlapping platform 131, and the fastener is a threaded fastener, a nut seat corresponding to the first mounting hole 312 is welded and fixed on the outer surface of the first overlapping platform 311 to achieve assembly with the threaded fastener; if the fastener is a straight-insertion snap-fit, there is no need to set a connecting seat on the outer side of the first overlapping platform 311; the implementation methods of other fasteners will not be listed here.

[0058] In some embodiments, see Figure 8 Multiple first mounting holes 312 are provided along the vertical direction, and multiple second mounting holes 132 are provided along the vertical direction, corresponding one-to-one with the first mounting holes 312. This embodiment fully expands the area of ​​the first overlapping platform 311 and the second overlapping platform 131, and makes full use of the space of the first overlapping platform 311 and the second overlapping platform 131, increasing the number of connection points and improving the bonding strength between the two.

[0059] In some embodiments, see Figures 1 to 3 To maintain the integrity of the vehicle body structure 1, the vehicle body structure 1 also includes a side outer panel assembly 500, which is connected to the outside of the side inner panel assembly 10. Based on this, the vehicle body structure 1 also includes a side inner panel front section assembly 300 and a lower body assembly 400. The lower part of the side inner panel front section assembly 300 is connected to the side of the lower body assembly 400 to form a lower body assembly 50. The frame formed by connecting the side outer panel assembly 500 and the side inner panel assembly 10 is a side panel assembly 60, which is connected to the outside of the lower body assembly 50.

[0060] In this embodiment, the assembly method of the vehicle body structure 1 is as follows:

[0061] For the first assembly, the side panel reinforcement plate assembly 200 is welded to the rear section of the side panel inner panel assembly 100 to form the side panel inner panel assembly 10. (See reference...) Figure 1 ;

[0062] The inner side panel assembly 10 and the outer side panel assembly 500 are welded together to form the side panel assembly 60. (See reference) Figure 1 ;

[0063] The front section of the side inner panel assembly 300 is welded to the lower body assembly 400 to form the lower body assembly 50. (See reference...) Figure 2 ;

[0064] The second assembly involves welding the lower body assembly 50 and the side assembly 60 to form body structure 1. (See reference...) Figure 3 .

[0065] By adjusting the welding sequence between the various assemblies, the problem of the sheet metal not being able to connect at the upper and lower ends of the C-pillar is avoided. At the same time, it can also ensure that the rear end of the upper side beam inner panel 310 in the front section assembly 300 of the side inner panel can be overlapped and fixed with the upper end of the C-pillar inner panel 130 in the rear section assembly 100 of the side inner panel. The overall integrity of the body structure 1 is stronger, which plays a positive role in improving the torsional stiffness and top pressure resistance of the body structure 1 itself.

[0066] Based on the same inventive concept, this application also provides a vehicle including the above-described body structure 1.

[0067] Compared with the prior art, the vehicle provided in this embodiment improves the torsional stiffness and anti-top pressure performance of the whole vehicle by adopting the above-mentioned body structure 1, thereby optimizing the driving safety of the whole vehicle and enhancing the market competitiveness of the product.

[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
