[0002] With the close integration of the automobile industry and high-tech, the cars produced will have longer driving range, more auxiliary equipment and entertainment equipment, etc., and therefore the cars will have a higher total weight, which means that such cars need better roof compression resistance and higher frame strength requirements for the whole vehicle. In addition, when a car rolls over, the extrusion caused by the contact between the top of the car body and the ground will cause the frame of the car to deform. The deformation of the car frame will increase the amount of intrusion into the interior space and cause greater harm to the occupants in the car. When the vehicle rolls over and collides, most of the pressure on the roof is transmitted laterally to other frames through the roof crossbeam to reduce the roof pressure and reduce the amount of intrusion into the interior space to provide a certain safe living space for the passengers. However, the existing roof crossbeam and side panel connection parts are not firm and stable, resulting in an unstable force transmission path, which cannot effectively guarantee the bending resistance of the connection parts and the roof crossbeam, and also reduces the safety and reliability of the car in the event of a collision or rollover.

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] In the description of the embodiments of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper" and "lower" is based on the orientation or positional relationship shown in the accompanying drawings. The term "connection" in this application, unless otherwise specified, mainly refers to a physical structural connection, and may also include meanings such as direct connection or indirect connection when specified. The terms "first" and "second" in the specification and claims of this application and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the term "includes" and any variations thereof are intended to cover non-exclusive inclusions.

[0027] See also Figure 1-Figure 3 , Figure 1 is a schematic structural block diagram of a car 100 in an embodiment of the present application, Figure 2 1 is a three-dimensional schematic diagram of the connection between the roof crossbeam 2 and the side panel 1 of the automobile 100 in the embodiment of the present application, Figure 3 for Figure 2 The automobile 100 includes a side panel 1 and a roof cross beam 2. The side panel 1 includes a first side panel 11 and a second side panel 12. The first side panel 11 and the second side panel 12 are respectively located on both sides of the automobile 100. The roof cross beam 2 is used to connect the first side panel 11 and the second side panel 12. The roof cross beam 2 includes a cross beam assembly 21. The cross beam assembly 21 includes a cross beam reinforcement plate 211. The cross beam reinforcement plate 211 includes a first side 2111 and a second side 2112 opposite to each other. The first side 2111 is overlapped on the first side panel 11, and the second side 2112 is overlapped on the second side panel 12.

[0028] Therefore, the length of the cross beam reinforcement plate 211 is extended, so that the two sides of the cross beam reinforcement plate 211 are overlapped on the first side panel 11 and the second side panel 12, and then the cross beam reinforcement plate 211 and the first side panel 11 and the second side panel 12 have a certain overlapping overlap length. Therefore, the extrusion force exerted on the first side panel 11 or the second side panel 12 is transmitted to the second side panel 12 or the first side panel 11 through the cross beam reinforcement plate 211, and the connection part between the roof cross beam 2 and the side panel 1 will be more stable and firm. The side panels 1 and the cross beam reinforcement plate 211 are overlapped and overlapped, which effectively improves the bending resistance of the overlapped portion between the side panels 1 and the cross beam reinforcement plate 211, reduces the risk of bending, and is more conducive to the transmission of lateral force, thereby effectively ensuring the effectiveness of the force transmission path when the automobile 100 is subjected to top pressure, and also improves the safety and reliability of the automobile 100 in the event of a collision or rollover, providing a certain safe living space for passengers in the event of a collision or rollover.

[0029] Please also read Figure 4 , Figure 4 for Figure 2 A cross-sectional view at point A. In some embodiments, as Figure 3 and Figure 4 As shown, the overlapping length of the first side 2111 and the first side panel 11 is in the range of 200-250 mm, and the overlapping length of the second side 2112 and the second side panel 12 is in the range of 200-250 mm.

[0030] Thus, the length of the first side 2111 overlapped on the first side panel 11, that is, the length of the overlapping part of the cross beam reinforcement plate 211 and the first side panel 11 is in the range of 200-250mm, and the second side 2112 overlapped on the second side panel 12, that is, the length of the overlapping part of the cross beam reinforcement plate 211 and the second side panel 12 is in the range of 200-250mm. The length of the overlapping part is between 200-250mm, which can more effectively improve the bending resistance of the overlapping part between the side panel 1 and the cross beam reinforcement plate 211, reduce the risk of bending, is more conducive to the transmission of lateral force, and effectively ensure the effectiveness of the force transmission path when the automobile 100 is subjected to top pressure.

[0031] In some embodiments, such as Figure 2 and Figure 3 As shown, the first side panel 11 includes a first A-pillar inner panel 111 and a first A-pillar reinforcement panel 112, the second side panel 12 includes a second A-pillar inner panel 121 and a second A-pillar reinforcement panel 122, the first A-pillar reinforcement panel 112 is located on a side of the first A-pillar inner panel 111 facing the second A-pillar inner panel 121, and extends along a first direction 13 toward a side of the second A-pillar inner panel 121, the second A-pillar reinforcement panel 122 is located on a side of the second A-pillar inner panel 121 facing the first A-pillar inner panel 111, and extends along a second direction 14 toward a side of the first A-pillar inner panel 111, wherein the first direction 13 and the second direction 14 are arranged in opposite directions.

[0032] Thus, the first A-pillar reinforcement plate 112 and the second A-pillar reinforcement plate 122 extend along the first direction 13 and the second direction 14 respectively, so as to increase the length of the overlapping portion between the cross beam reinforcement plate 211 and the side panel 1, further improving the continuity and stability of the lateral force transmission path of the roof cross beam 2. In addition, the overlapping portion between the side panel 1 and the cross beam reinforcement plate 211 effectively improves the bending rigidity of the overlapping portion between the side panel 1 and the cross beam reinforcement plate 211, which is more conducive to the transmission of lateral force.

[0033] In some embodiments, such as Figure 3 and Figure 4 As shown, the first side 2111 is fixedly connected to the first A-pillar reinforcement plate 112 through a welding point 25 and a structural adhesive 26 , and the second side 2112 is fixedly connected to the second A-pillar reinforcement plate 122 through a welding point 25 and a structural adhesive 26 .

[0034] Thus, the cross beam reinforcement plate 211 is fixedly overlapped on the side panel 1 through the welding point 25 and the structural adhesive 26, which further stabilizes the force transmission path and enhances the connectivity between the cross beam reinforcement plate 211 and the side panel 1; and the presence of the structural adhesive 26 reduces the risk of failure of the welding point 25 and improves the overall safety of the roof cross beam 2.

[0035] In some embodiments, such as Figure 3 and Figure 4 As shown, the first A-pillar inner panel 111 and the first A-pillar reinforcement panel 112 are connected via the welding point 25 and the structural adhesive 26 , and the second A-pillar inner panel 121 and the second A-pillar reinforcement panel 122 are connected via the welding point 25 and the structural adhesive 26 .

[0036] Please also read Figure 5 and Figure 6 , Figure 5 for Figure 2 The cross-section at point B, Figure 6 for Figure 2 A cross-sectional view at C. In some embodiments, as Figure 3 and Figure 6 As shown, a mounting portion 2113 is provided at the middle position of the cross beam reinforcement plate 211, and the mounting portion 2113 is used to mount the radar 4 of the automobile 100. The thickness of the mounting portion 2113 is thinner than the thickness of the cross beam reinforcement plate 211 excluding the mounting portion 2113. The cross beam assembly 21 also includes a cross beam plate 212 and a connecting plate 213. The cross beam plate 212 connects the cross beam reinforcement plate 211, the connecting plate 213, the first side panel 11 and the second side panel 12 to form a cavity. The roof cross beam 2 includes a first reinforcement assembly 22, and the first reinforcement assembly 22 is installed in the cavity between the mounting portion 2113 and the cross beam plate 212, and connects the mounting portion 2113 and the cross beam plate 212.

[0037] Thus, the thickness of the installation portion 2113 is reduced due to the corresponding avoidance of the installation of the radar 4, which makes the middle part of the roof cover beam 2 prone to bending, and the first reinforcing component 22 is installed and filled in the cavity, so that the first reinforcing component 22 connects the installation portion 2113 and the beam plate 212, thereby ensuring the bending resistance of the middle part of the roof cover beam 2 and the lateral force transmission path of the automobile 100 when it is under top pressure; and further improving the top pressure resistance performance of the roof cover beam 2, effectively preventing the top cover beam 2 from bending in the middle part.

[0038] In some embodiments, such as Figure 6 As shown, the radar 4 is fixed to the mounting portion 2113 by four bolts 41 .

[0039] Please also read Figure 7 , Figure 7 FIG. 2 is a perspective schematic diagram of the first connecting plate 2131 connecting the cross beam plate 212 and the first A-pillar inner plate 111 in the embodiment of the present application. Figure 3 and Figure 8 As shown, the connecting plate 213 includes a first connecting plate 2131 and a second connecting plate 2132, the first connecting plate 2131 is located on the side of the cross beam plate 212 away from the cross beam reinforcement plate 211, one side of the first connecting plate 2131 is connected to the cross beam plate 212, and the other side of the first connecting plate 2131 is connected to the first A-pillar inner plate 111, the second connecting plate 2132 is located on the side of the cross beam plate 212 away from the cross beam reinforcement plate 211, one side of the second connecting plate 2132 is connected to the cross beam plate 212, and the other side of the second connecting plate 2132 is connected to the second A-pillar inner plate 121.

[0040] Thus, the first connecting plate 2131 and the second connecting plate 2132 connect the cross beam plate 212 and the side panel 1 together, thereby improving the connectivity and stability of the roof cross beam 2.

[0041] The length of the first connecting plate 2131 connecting the first A-pillar inner plate 111 is 300 mm, and the length of the second connecting plate 2132 connecting the second A-pillar inner plate 121 is 300 mm.

[0042] In some embodiments, such as Figure 3 and Figure 5 As shown, the side of the cross beam plate 212 is bent and extends toward the cross beam reinforcement plate 211, the side of the cross beam reinforcement plate 211 is bent and extends toward the cross beam plate 212, and the side of the cross beam plate 212 and the side of the cross beam reinforcement plate 211 are fixedly connected to achieve the connection between the cross beam plate 212 and the cross beam reinforcement plate 211.

[0043] In some embodiments, the connecting plate 213, the beam reinforcement plate 211 and the beam plate 212 are connected by the welding points 25 and / or the structural adhesive 26 to strengthen the connection and reduce the risk of connection failure of the top cover beam 2.

[0044] In some embodiments, such as Figure 3 As shown, the length of the first reinforcing component 22 is greater than the length of the mounting portion 2113 .

[0045] Therefore, the first reinforcing component 22 completely covers the middle portion of the roof cross beam 2 and extends to both ends by a certain length, so as to ensure the strength of the middle portion of the roof cross beam 2 and the bending resistance of the roof cross beam 2 .

[0046] Please also read Figure 8 , Figure 8 for Figure 3 Enlarged view at D. In some embodiments, the first reinforcement assembly 22 includes a first frame 221 and a first filler 222 , the first frame 221 and the first filler 222 are fixedly connected, the first filler 222 fixes the first frame 221 on the cross beam 212 , and connects the mounting portion 2113 and the cross beam 212 .

[0047] Thus, the first filling piece 222 fixes the first frame 221 in the cavity, and fixedly connects the first frame 221, the bottom of the mounting portion 2113 and the crossbeam plate 212, thereby ensuring the bending resistance of the middle portion of the top cover crossbeam 2, further improving the top pressure resistance of the top cover crossbeam 2, and effectively preventing bending of the middle portion of the top cover crossbeam 2.

[0048] In some embodiments, the first frame 221 is a CBS (Composite Body Solutions) frame, the first filling piece 222 is CBS expansion glue, the CBS frame is pasted in the cavity by the CBS expansion glue, and the mounting portion 2113 and the cross beam plate 212 are connected by the CBS expansion glue. Compared with the sheet metal structure, the structure of the CBS frame and the CBS structural glue 26 can make the weight of the automobile 100 lighter, thereby meeting the lightweight demand of the automobile 100.

[0049] In some embodiments, such as Figure 3As shown, the roof cover beam 2 also includes a second reinforcement component 23 and a third reinforcement component 24. The second reinforcement component 23 is installed on the connection portion formed by the first connecting plate 2131 connecting the beam plate 212, and connects the beam plate 212, the first connecting plate 2131 and the beam reinforcement plate 211. The third reinforcement component 24 is installed on the connection portion formed by the second connecting plate 2132 connecting the beam plate 212, and connects the beam plate 212, the second connecting plate 2132 and the beam reinforcement plate 211.

[0050] Thus, the second reinforcing assembly 23 and the third reinforcing assembly 24 are respectively installed at the connecting parts on both sides of the connecting plate 213 and the cross beam plate 212, so as to enhance the rigidity of the connecting parts and improve the rigidity and bending resistance of both sides of the roof cross beam 2.

[0051] Please also read Fig. 9 and Fig.10 , Fig. 9 for Figure 3 The enlarged view at E, Fig.10 for Figure 3 Enlarged view at F. In some embodiments, Fig. 9 As shown, the second reinforcement assembly 23 includes a second frame 231 and a second filling piece 232 . The second frame 231 and the second filling piece 232 are fixedly connected. The second filling piece 232 fixes the second frame 231 to the connecting plate 213 and the cross beam plate 212 .

[0052] In some embodiments, such as Fig.10 As shown, the third reinforcement assembly 24 includes a third frame 241 and a third filling piece 242 . The third frame 241 and the third filling piece 242 are fixedly connected. The third filling piece 242 fixes the third frame 241 to the connecting plate 213 and the cross beam plate 212 .

[0053] In some embodiments, such as Figure 3 and Figure 4 As shown, the second skeleton 231 is fixedly connected to the cross beam plate 212 and the first connecting plate 2131 through the welding point 25 and the second filling piece 232, and the third skeleton 241 is fixedly connected to the cross beam plate 212 and the second connecting plate 2132 through the welding point 25 and the second filling piece 232.

[0054] In some embodiments, the second frame 231 and the third frame 241 are CBS frames, and the second filling piece 232 and the third filling piece 242 are CBS expansion glue. The CBS expansion glue will expand due to heat after being baked at high temperature. Therefore, the CBS frame is adhered to the connecting plate 213 and the cross beam plate 212 through the CBS expansion glue, and the cross beam plate 212, the cross beam reinforcement plate 211 and the connecting plate 213 are bonded together.

[0055] In some embodiments, such as Fig. 9 and Fig.10 As shown, the second reinforcement assembly 23 includes a first reinforcement segment 233 and a second reinforcement segment 234, the first reinforcement segment 233 is installed on the first connection portion 27 on the first connecting plate 2131, and the second reinforcement segment 234 is installed on the second connection portion 28 on the beam plate 212, wherein the first connection portion 27 and the second connection portion 28 constitute the connection portion formed by the first connecting plate 2131 connecting the beam plate 212, and the third reinforcement assembly 24 includes a third reinforcement segment 243 and a fourth reinforcement segment 244, the third reinforcement segment 243 is installed on the third connection portion 29 on the second connecting plate 2132, and the fourth reinforcement segment 244 is installed on the fourth connection portion 30 on the beam plate 212, wherein the third connection portion 29 and the fourth connection portion 30 constitute the connection portion formed by the second connecting plate 2132 connecting the beam plate 212.

[0056] Thus, the second reinforcement component 23 and the third reinforcement component 24 are each divided into two parts and installed on the first connection part 27, the second connection part 28, the third connection part 29 and the fourth connection part 30. The second reinforcement component 23 and the third reinforcement component 24 are designed as two-section types, which is convenient for the connection of the connecting plate 213 to the cross beam plate 212, facilitates the upper operation, and can also effectively enhance the stiffness of each connection part, thereby improving the stiffness and bending resistance of both sides of the top cover cross beam 2.

[0057] In some embodiments, the cross beam plate 212 and the connecting plate 213 are made of hot-formed steel material, and the cross beam reinforcement plate 211 is made of high-strength steel material.

[0058] Thus, the cross beam plate 212 and the connecting plate 213 are made of hot-formed steel material, and the cross beam reinforcement plate 211 is made of high-strength steel material, which further enhances the rigidity of the roof cross beam 2, effectively improves the bearing capacity of the roof cross beam 2, and improves the bending resistance of the roof cross beam 2. While improving the rigidity of the roof cross beam 2, the production difficulty of the automobile 100 is reduced, and the weight of the automobile 100 is reduced.

[0059] The high-strength steel material is a steel material with a yield strength of 210-550 MPa and a tensile strength of 340-780 MPa.
