DETAILED DESCRIPTION

[0045] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the embodiments set forth herein is illustrative and explanatory in nature and not restrictive of the disclosure. In other words, the disclosure is not limited to the embodiments set forth herein, but the

[0046] In the present disclosure, the orientation words up, down, left, right, front, back refer to the up, down, left, right, front, back defined by the vehicle in the normal use state, and the specific can refer to Figure 1 The terms used, such as "first", "second", are only used to distinguish one element from another element, and do not have sequential and important nature, and the multiple in the present application refers to two or more and includes two.

[0047] In the description of the present disclosure, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0048] Referring to Figures 1 to 5 The present disclosure provides a vehicle body structure, which comprises an A-pillar 5, a front roof cross beam 6 and a cross beam joint 7; the front roof cross beam 6 extends along the left-right direction, and the end of the front roof cross beam 6 is connected with the A-pillar 5 through the cross beam joint 7; wherein the cross beam joint 7, the A-pillar 5 and the front roof cross beam 6 surround the joint cavity 70.

[0049] In the above technical solution, the front roof cross beam 6 and the A-pillar 5 are connected through the cross beam joint 7, and a joint cavity 70 is surrounded, so that the connection strength between the front roof cross beam 6 and the A-pillar 5 can be significantly improved, and the end of the front roof cross beam 6 can resist the impact force from the roof area; in addition, the surrounded joint cavity 70 can effectively disperse and absorb the impact force during the collision, and improve the safety performance.

[0050] In an embodiment, referring to Figure 3 and Figure 4 As shown in the figures, the inside of the front roof cross beam 6 is formed with a cross beam cavity 60 extending along the left-right direction, and the joint cavity 70 is communicated with the cross beam cavity 60.

[0051] In this embodiment, by communicating the joint cavity 70 with the cross beam cavity 60, a continuous and reinforced structural frame is formed, which not only increases the overall rigidity of the roof area, but also can provide stronger support force in the collision or rollover accident, ensure the ability to resist impact force deformation, and improve the safety performance of the vehicle.

[0052] Secondly, the design of the communication between the joint cavity 70 and the cross beam cavity 60 can allow the impact force to be transmitted and dispersed through the cross beam cavity 60 and the joint cavity 70 when the collision occurs, reducing the possibility of local stress concentration.

[0053] In addition, by connecting the beam cavity 60 and the joint cavity 70, the energy absorption path can be optimized, so that the impact capacity can be more effectively absorbed, improving safety.

[0054] Optionally, as shown in Figure 1 and Figure 2 , the joint cavity 70 is divergent in the direction away from the roof front beam 6. Because the joint cavity 70 is divergent, the energy generated by the collision can be gradually dispersed to a larger area, reducing local stress concentration. Among them, for the beam joint 7, the extension of the beam joint 7 in the front and rear direction is "outer eight" in the left and right direction and away from the roof front beam 6, and the extension of the beam joint 7 in the up and down direction also gradually extends downward.

[0055] Optionally, as shown in Figures 1 to 4 , the roof front beam 6 includes a beam upper plate 61 and a beam lower plate 62, which extend in the left and right direction and are connected in the up and down direction to define a beam cavity 60; the end of the beam upper plate 61 is connected with the A-pillar 5, and the end of the beam lower plate 62 is connected with the A-pillar 5 through the beam joint 7; the beam joint 7, the A-pillar 5 and the beam lower plate 62 surround the joint cavity 70.

[0056] In this embodiment, the beam upper plate 61 and the beam lower plate 62 are connected in the up and down direction to form the beam cavity 60, which can significantly enhance the overall rigidity and bending resistance of the roof front beam 6. At the same time, this double-layer structure design can effectively disperse external forces from different directions, improving the safety of the vehicle in a collision. In addition, the design of the joint cavity 70 can provide an additional energy absorption path when a collision occurs, which can guide and disperse the shock wave to some extent, effectively absorbing and dispersing the collision energy and protecting the safety of the passengers in the vehicle.

[0057] In one embodiment, as shown in Figure 4 , the A-pillar 5 includes an A-pillar outer plate 52 and an A-pillar inner plate 51 which are connected; the end of the beam upper plate 61 is connected with the A-pillar outer plate 52, and the end of the beam lower plate 62 is connected with the A-pillar inner plate 51 through the beam joint 7; the beam joint 7, the A-pillar inner plate 51 and the beam lower plate 62 surround the joint cavity 70.

[0058] In this embodiment, the beam upper plate 61 is connected to the A-pillar outer plate 52, while the beam lower plate 62 is connected to the A-pillar inner plate 51 through the beam joint 7, forming a double-layer support structure. This design can effectively increase the rigidity and strength of the connection area of the roof front beam 6 and the A-pillar 5.

[0059] In another embodiment, as shown in Figure 2 and Figure 5As shown, the cross beam joint 7 comprises a first joint segment 71 and a second joint segment 72 connected to each other, the first joint segment 71 is connected to the front roof cross beam 6 in an overlapping manner, and the second joint segment 72 is used to surround the joint cavity 70.

[0060] In this embodiment, the overlapping connection of the first joint segment 71 to the front roof cross beam 6 can significantly increase the strength and stability of the connection between the cross beam joint 7 and the front roof cross beam 6. Secondly, through the overlapping connection, the contact area can be increased, thereby dispersing the stress and reducing the risk of failure due to local stress concentration, thereby improving the stability of the entire vehicle body structure. In addition, the first joint segment 71 not only provides the function of connection, but also plays the role of support and reinforcement, which helps to improve the overall load-bearing capacity of the front roof cross beam 6.

[0061] Optionally, the first joint segment 71 extends in the left-right direction with a size of not less than 95 mm. That is, the overlapping area between the cross beam joint 7 and the front roof cross beam 6 in the left-right direction has a size of not less than 95 mm, which ensures that the overlapping area between the cross beam joint 7 and the front roof cross beam 6 is larger, and a larger overlapping area means higher connection strength and rigidity. In addition, a larger overlapping area helps to better disperse external forces and impacts from different directions, avoiding local stress concentration and reducing the risk of fatigue damage or fracture caused by local excessive stress. For example, the first joint segment 71 extends in the left-right direction with a size of 100 mm, but the present disclosure does not limit the specific size.

[0062] In one embodiment, the first joint segment 71 and the front roof cross beam 6 are connected by at least one row of joint spot welds, and each row of joint spot welds comprises a plurality of joint spot welds arranged in pairs in the front-rear direction.

[0063] In this embodiment, by using the connection mode of multiple joint spot welds, uniform distribution of stress can be achieved, and compared with the concentrated welding mode, the distributed joint spot welds can effectively avoid stress concentration and reduce the risk of fatigue cracks or fractures caused by stress concentration.

[0064] Secondly, the plurality of spaced joint spot welds help to more effectively disperse impact energy during a collision, as the joint spot welds are distributed over a larger area, the structure can absorb energy through more paths when impacted, thereby further protecting the safety of passengers in the vehicle.

[0065] In another embodiment, the first joint segment 71 and the front roof cross beam 6 are also connected by adhesive bonding.

[0066] In this embodiment, welding provides a high-strength mechanical connection, while the adhesive provides additional bonding force through intermolecular forces. This dual fixing mechanism significantly enhances the overall strength and rigidity of the joint. Secondly, the adhesive can evenly distribute stress in the area between weld points, reducing localized stress concentration and further improving fatigue resistance and durability. Additionally, the adhesive has certain energy absorption properties, absorbing some impact energy during collisions and reducing the energy transferred to the weld points.

[0067] Optionally, the joint solder joint group can be set to at least two rows, with adjacent rows of joint solder joint groups spaced apart in the left-right direction.

[0068] In this embodiment, by setting at least two rows of joint weld point groups, the number and distribution density of connection points are increased, significantly improving the connection strength and rigidity between the first joint segment 71 and the front crossbeam 6 of the roof. Secondly, the multiple rows of joint weld point groups spaced apart in the left-right direction can more evenly distribute stress, avoiding localized stress concentration and reducing the risk of fatigue cracks or fractures caused by stress concentration. Furthermore, the multiple rows of joint weld point groups provide more energy absorption paths, enabling the structure to more effectively disperse and absorb energy when subjected to impact.

[0069] In other implementations, refer to Figure 2 and Figure 5 As shown, the second connector section 72 includes a connector base plate 721, a connector front side plate 722, and a connector rear side plate 723. The connector base plate 721 is connected to the first connector section 71 on one side in the left-right direction and to the A-pillar 5 on the other side. The connector front side plate 722 is connected to the first connector section 71 on one side in the left-right direction and to the A-pillar 5 on the other side. The connector rear side plate 723 is connected to the first connector section 71 on one side in the left-right direction and to the A-pillar 5 on the other side. The connector front side plate 722 is connected to the front side of the connector base plate 721, and the connector rear side plate 723 is connected to the rear side of the connector base plate 721. Furthermore, the sides of the connector front side plate 722 and the connector rear side plate 723 furthest from the connector base plate are connected to at least the A-pillar 5.

[0070] In this embodiment, a multi-faceted support structure is first formed by setting a joint base plate 721, a joint front side plate 722, and a joint rear side plate 723. This design significantly enhances the overall strength and rigidity of the entire beam joint 7. The mutual support between the plates can effectively disperse stress from different directions, improving the stability and deformation resistance of the beam joint 7.

[0071] Secondly, each panel (joint base plate 721, joint front side plate 722 and joint rear side plate 723) is connected to the first joint section 71 on one side in the left and right directions, and connected to the A-pillar on the other side, forming a three-dimensional connection structure and improving the firmness of the structural connection.

[0072] In addition, when the vehicle is in a collision, the impact energy can be dispersed and absorbed by the joint bottom plate 721, the joint front side plate 722 and the joint rear side plate 723 working together.

[0073] Optionally, referring to Figure 2 As shown, the joint bottom plate 721 gradually extends downward in the left-right direction and away from the first joint segment 71, the joint front side plate 722 gradually extends forward in the left-right direction and away from the first joint segment 71, and the joint rear side plate 723 gradually extends rearward in the left-right direction and away from the first joint segment 71.

[0074] In this embodiment, first, the extension arrangement of the joint bottom plate 721, the joint front side plate 722 and the joint rear side plate 723 can increase the contact area with the A-pillar 5, providing a larger support surface, thereby increasing the strength and deformation resistance of the connection between the cross beam joint 7 and the A-pillar. Second, the joint front side plate 722 gradually extends forward, the joint rear side plate 723 gradually extends rearward, and the joint bottom plate 721 gradually extends downward, which means that the space of the joint cavity 70 gradually increases in the direction away from the first joint segment 71, forming a gradually expanding cavity that can guide and disperse the shock wave during a collision, thereby improving the deformation resistance.

[0075] In one embodiment, referring to Figure 2 and Figure 5 As shown, the second joint segment 72 further comprises a front side joint flange 724 and a rear side joint flange 725, the front side joint flange 724 is connected to the joint front side plate 722 and extends forward, and the front side joint flange 724 is connected to the front roof cross beam 6 and the A-pillar 5; the rear side joint flange 725 is connected to the joint rear side plate 723 and extends rearward, and the rear side joint flange 725 is connected to the front roof cross beam 6 and the A-pillar 5.

[0076] In this embodiment, first, the front side joint flange 724 and the rear side joint flange 725 extend forward and rearward respectively, and are connected to the front roof cross beam 6 and the A-pillar 5, significantly increasing the connection area, which not only enhances the rigidity and deformation resistance of the cross beam joint 7 area, but also facilitates the effective transmission of impact force from the roof at the cross beam joint 7.

[0077] Second, by increasing the front side joint flange 724 and the rear side joint flange 725 in the front-rear direction, more support points are formed, making the structure more stable in multiple dimensions and reducing the problem of local stress.

[0078] In addition, the front side joint flange 724 and the rear side joint flange 725 provide an additional energy absorption path, which can more effectively disperse impact energy during a collision and improve safety performance.

[0079] Optionally, referring to Figure 1 and Figure 2 As shown, the A-pillar 5 includes an A-pillar inner panel 51, which includes an A-pillar inner side panel 511 and an A-pillar inner top panel 512 connected to an upper end of the A-pillar inner side panel 511 and extending in the left-right direction toward the inside of the vehicle; the front-side joint flange 724 is connected to the A-pillar inner side panel 511 and the A-pillar inner top panel 512, and the rear-side joint flange 725 is connected to the A-pillar inner side panel 511 and the A-pillar inner top panel 512.

[0080] In this embodiment, by designing the A-pillar inner panel 51 as the A-pillar inner side panel 511 and the A-pillar inner top panel 512, and connecting the front-side joint flange 724 and the rear-side joint flange 725 to the two parts respectively, a more complex three-dimensional support structure is formed, further increasing the strength and rigidity of the connection between the cross beam joint 7 and the A-pillar 5.

[0081] Secondly, the front-side joint flange 724 and the rear-side joint flange 725 are not only connected to the A-pillar inner side panel 511, but also to the A-pillar inner top panel 512, and are connected to the A-pillar 5 in different areas and directions, making the connected cross beam joint 7 and A-pillar 5 more stable and reducing local stress concentration.

[0082] In addition, the structure in different areas and directions provides multiple energy absorption paths, which can guide and absorb shock waves in different directions in the event of a collision, improving safety performance.

[0083] In another embodiment, referring to Figure 1 and Figure 2 As shown, the A-pillar inner panel 51 further includes an A-pillar inner bottom panel 513 connected to a lower end of the A-pillar inner side panel 511 and extending in the left-right direction toward the outside of the vehicle; the second joint section 72 further includes a bottom-side flange 726 connected to the A-pillar inner bottom panel 513, and the bottom-side flange 726 is connected in sequence to the front-side joint flange 724, the joint bottom panel 721, and the rear-side joint flange 725 in the front-rear direction.

[0084] In this embodiment, first, by extending the A-pillar inner bottom panel 513 in the left-right direction toward the outside of the vehicle and connecting it to the lower end of the A-pillar inner side panel 511, this design can effectively increase the overall rigidity of the A-pillar. Secondly, the bottom-side flange 726 is connected in sequence to the front-side joint flange 724, the joint bottom panel 721, and the rear-side joint flange 725 in the front-rear direction, forming a continuous reinforcing structure. This not only helps to disperse and bear forces from different directions, but also reduces fatigue damage caused by long-term vibration or stress concentration.

[0087] Secondly, by locating the rear corner panel 73 in the rear corner gap 730, the energy absorption path can be optimized, which helps to better disperse the impact force in the event of a side or rollover accident, thereby protecting the safety of the passengers in the vehicle.

[0088] In addition, the rear corner panel 73 is arranged in the space of the rear corner gap 730, which not only does not increase the additional space occupation, but also improves the space utilization of the overall structure through this compact design.
