Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive body technology, and in particular to a body structure. Background Technology

Detailed Implementation
[0047] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0048] Reference Figures 1 to 3 As shown, this utility model provides a vehicle body structure, including a side ring 1, a top ring 5, a D ring 9, and a rear C ring 13, wherein:
[0049] Reference Figure 4 As shown, the side ring 1 includes a side outer panel 2 and a wheel arch outer panel 3. The side outer panel 2 and...
[0050] A first reinforcing plate 4 is provided between the outer plates 3 of the wheel cover. The two ends of the first reinforcing plate 4 are connected to the outer plates 2 of the side wall and the outer plates 3 of the wheel cover, respectively. The first reinforcing plate 4 can enhance the connection strength between the outer plates 2 of the side wall and the outer plates 3 of the wheel cover.
[0051] Reference Figure 5 As shown, the top ring 5 includes a top cover 6 and a rear crossbeam inner plate 7. A second reinforcing plate 8 is provided between the top cover 6 and the rear crossbeam inner plate 7. The two ends of the second reinforcing plate 8 are connected to the top cover 6 and the rear crossbeam inner plate 7, respectively. The second reinforcing plate 8 is the outer plate of the rear crossbeam. The second reinforcing plate 8 can enhance the connection strength between the top cover 6 and the rear crossbeam inner plate 7.
[0052] Reference Figure 6As shown, the D-ring 9 includes an inner D-pillar panel 10, an outer D-pillar panel 11, and a side panel 2. The inner D-pillar panel 10 and the outer D-pillar panel 11 are located on the same side of the side panel 2. A third reinforcing plate 12 is provided between the outer D-pillar panel 11 and the inner D-pillar panel 10. The third reinforcing plate 12 is a D-pillar reinforcing plate. Both ends of the third reinforcing plate 12 are connected to the inner D-pillar panel 10 and the outer D-pillar panel 11, respectively. The third reinforcing plate 12 is used to enhance the connection strength between the outer D-pillar panel 11 and the inner D-pillar panel 10.
[0053] The rear C-ring 13 includes the rear floor 14, the outer side panel 2, the inner rear side panel 15, and the inner D-pillar panel 10, as shown in the reference. Figure 7 As shown, a rear floor beam 16 is provided on the rear floor 14, which enhances the rigidity of the rear floor 14. (Refer to...) Figure 8 As shown, the rear side inner panel 15 is connected to the D-pillar inner panel 10. A fourth reinforcing plate 17 is provided on the side of the rear side inner panel 15 away from the side outer panel 2. The fourth reinforcing plate 17 is used to enhance the rigidity of the rear side inner panel 15.
[0054] Compared to existing vehicle body structures, the side ring 1, top ring 5, B ring 47, front C ring 48, rear C ring 13, and D ring 9 all have unconnected sections, resulting in poor overall vehicle body rigidity. In the embodiments provided in this application, by setting a first reinforcing plate 4, a second reinforcing plate 8, a third reinforcing plate 12, a rear floor crossbeam 16, and a fourth reinforcing plate 17 in the side ring 1, top ring 5, D ring 9, and rear C ring respectively, the unconnected sections of the vehicle body rings are connected, making them interlocked. This improves the overall torsional rigidity, bending rigidity, and modal rigidity of the vehicle body. When the vehicle is driving on a ring road or a tortuous road, it avoids large torsional deformation of the vehicle body and can greatly reduce the risk of abnormal noise.
[0055] Reference Figure 9 as well as Figure 10 As shown, the rear C-ring 13 includes a lower C-ring connector 18, which includes a rear wheel arch inner plate 19 and a rear beam 20. Multiple first connection points 21 are provided between the rear wheel arch inner plate 19 and the rear beam 20. These first connection points 21 are formed by spot welding and structural adhesive 46. The lower C-ring connector 18 is a critical location for vehicle body torsion and is welded between major vehicle body assemblies (upper body 41 and lower body 42). The matching at this location is complex, and there are risks of incomplete welds, weld detachment, and fatigue tearing. Given the interlocking nature of the aforementioned frame, further structural reinforcement at this location can effectively reduce the risk of various abnormal noises.
[0056] In one feasible implementation, the first connection point 21 is formed by a combination of spot welding and structural adhesive 46. In order to make the connection between the rear wheel arch inner plate 19 and the rear beam 20 more reliable and rigid, and to avoid the risks of incomplete welding, detachment, and fatigue tearing, the spacing between adjacent first connection points 21 should be less than 40mm. The small spacing between adjacent first connection points 21 can avoid the failure of structural adhesive 32 due to large gaps, thereby avoiding potential abnormal noise risks.
[0057] Furthermore, referring to Figure 11 As shown, due to the significant risk of abnormal noise from the C-ring lower joint 18, in order to avoid connection failure and abnormal noise risks caused by incomplete welding, the number of welding layers of the parts 50 between the rear wheel cover 35 and the rear beam 20 should be no more than 3 layers. Too many welding layers can easily lead to incomplete welding. The welding thickness between the inner plate 19 of the rear wheel cover 35 and the rear beam 20 should be less than or equal to 4mm. Thicker welding positions can easily lead to connection failure.
[0058] Reference Figure 12 As shown, the rear wheel arch inner plate 19 is laser-welded to divide it into a soft area 43 and a hard area 44. The thicker rear wheel arch inner plate 19 has better resistance to deformation, and the high-strength material can also prevent weld failure. The combination of the two can effectively avoid the risk of abnormal noise. In addition, the soft area 43 is a difficult part of stamping, and using soft material can prevent forming cracks.
[0059] The vehicle body structure of this application includes an upper body 41 and a lower body 42, wherein the upper body 41 and the lower body 42 are in... Figure 12 The soft area 43 shown in the diagram adopts a 0.8mm gap design, while the hard area 44 adopts a conventional 0-fit design. Here, the upper body 41 and the lower body 42 are U-shaped surfaces matched (as shown by the black line). The surface is complex and the matching is difficult. The hard area 44 is thick, hard, and has many surrounding parts, while the soft area is made of soft material, has fewer surrounding parts, and has a simple structure. The soft area 43 adopts a 0.8mm gap design to make the surface of the hard area 44 fit better, which can prevent the risk of weld failure and abnormal noise caused by the difficulty of dimensional matching of the hard area 44.
[0060] Reference Figure 13 as well as Figure 14As shown, the vehicle body structure also includes a D-pillar upper connector 22, which includes a roof crossbeam 23 and a fifth reinforcing plate 24. The fifth reinforcing plate 24 is connected to the roof crossbeam 23 and serves as a top beam reinforcing plate to improve the rigidity of the D-pillar upper connector 22. The roof crossbeam 23 has a width of 130mm and a thickness of 1.0mm, while the fifth reinforcing plate 24 has a thickness of 1.2mm. Compared to the dimensions of the roof crossbeam 23 in the prior art, this application increases the width and thickness of the roof crossbeam 23, and, under the action of the fifth reinforcing plate 24, increases the cross-sectional area of the D-pillar upper connector 22, thereby improving the rigidity of the D-pillar upper connector 22 and reducing the risk of excessive connector deformation.
[0061] Reference Figure 15 as well as Figure 16 As shown, the vehicle body structure includes a tailgate latch 25, which comprises an inner tailgate panel 26, an outer tailgate panel 27, and a latch mounting plate 28. The two ends of the latch mounting plate 28 are connected to the inner tailgate panel 26 and the outer tailgate panel 27, respectively. The latch mounting plate 28 and the inner tailgate panel 26 are fixedly connected by structural adhesive 32. The latch mounting plate 28 provides the mounting for the tailgate lock; its rigidity will affect the amount of deformation of the tailgate under torsional conditions.
[0062] Compared to the latch mounting plate 28 in the prior art, this application increases the area of the latch mounting plate 28, allowing it to connect simultaneously to both the inner panel 26 and the outer panel 27 of the tailgate, thereby improving the rigidity of the tailgate latch 25. The latch mounting plate 28 is fixedly connected to the inner panel 26 of the tailgate using structural adhesive 32, which effectively reduces tailgate deformation and avoids the risk of abnormal noise due to excessive deformation.
[0063] Reference Figure 17 as well as Figure 18 As shown, the vehicle body structure also includes a B-pillar latch mounting surface 29, which includes a side outer panel 2 and a B-pillar reinforcing plate 30. The side outer panel 2 and the B-pillar reinforcing plate 30 are connected by fasteners 31 and structural adhesive 32. Due to manufacturing tolerances, relying solely on fasteners 31 to connect the B-pillar latch mounting surface 29 will result in poor surface fit and may easily cause abnormal noise. Adding structural adhesive 32 between the side outer panel 2 and the B-pillar reinforcing plate 30, in conjunction with fasteners 31, can compensate for some of the manufacturing tolerances.
[0064] Reference Figure 19 as well as Figure 20 As shown, the vehicle body structure also includes a C-pillar latch mounting surface 33, which includes a side outer panel 2, a C-pillar reinforcing plate 34, and a rear wheel cover 35. The two ends of the C-pillar reinforcing plate 34 are connected to the side outer panel 2 and the rear wheel cover 35, respectively. Structural adhesive 32 is provided between the C-pillar reinforcing plate 34 and the side outer panel 2.
[0065] Compared to existing technologies, this application integrates independent, small latch reinforcement plates onto the C-pillar reinforcement plate 34 and then fixes them together with structural adhesive 32. The integrated reinforcement plate is used to install the rear door. Its rigidity will affect the amount of deformation of the rear door under torsional conditions. Therefore, by strengthening the structure at the latch and connecting it with fasteners 31 and structural adhesive 32 at the same time, the surface fit can be better, thereby avoiding abnormal noise caused by excessive deformation of the rear door.
[0066] Reference Figure 21 as well as Figure 22 As shown, the side ring 1 includes an upper A-pillar reinforcing plate 37 and an upper side beam reinforcing plate 38. The upper A-pillar reinforcing plate 37 and the upper side beam reinforcing plate 38 are fixedly connected by spot welding. Using spot welding instead of pure structural adhesive 32 to connect the side ring 1 can avoid the risk of abnormal noise caused by the failure of pure structural adhesive 32.
[0067] Because the conditions for using structural adhesive 32 for bonding are quite demanding, requiring the surface gap to be ≤0.5mm, but in actual manufacturing, due to cumulative tolerances, there is often a small probability that the tolerance gap is ≥0.5mm, which causes the structural adhesive 32 to fail in some models and produce abnormal noises. Structural adhesive 32 requires that the vehicle body vibration be small during the painting, baking and hardening process, otherwise the structural adhesive 32 is prone to failure and abnormal noises.
[0068] Reference Figure 23 as well as Figure 24 As shown, the vehicle body structure includes a rear side panel 15 and an upper side beam panel 39. The rear side panel 15 and the upper side beam panel 39 have multiple second connection points 40, which are welded together to fix the rear side panel 15 and the upper side beam panel 39 together.
[0069] Existing technologies mainly use pure fasteners 31 for connection. However, fasteners 31 are prone to omissions during manufacturing. When they are omitted, the surfaces at that point are not connected, which can lead to relative displacement between the surfaces and cause abnormal noise. During the final assembly process, the installation torque of fasteners 31 is theoretically within the set range, but in actual production, there is a risk that some vehicles may have insufficient torque. When the torque is insufficient, the parts may cause abnormal noise. During vehicle use, fasteners 31 also have the risk of torque attenuation due to stress release.
[0070] The embodiments provided by this utility model eliminate the pure fastener 31 connection in the body part. The new structural design uses CO2 welding to replace the fastener 31 connection, reducing the source of abnormal noise risk.
[0071] This application improves the overall rigidity of the vehicle body and effectively reduces the risk of abnormal noise by setting reinforcing plates on the side ring 1, top ring 5, D ring 9 and rear C ring 13, and enhancing the connection strength of the upper B-pillar connector 49, lower C-ring connector 18, upper D-pillar connector 35 and lower D-pillar connector 51 respectively.
[0072] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
