[0045] The A column inner plate upper section 111 is an important part of the A column inner plate 11, and it is located at a high position of the vehicle body, plays an important role in resisting impact from the top of the vehicle and maintaining the stability of the vehicle body structure. The first sub-reinforcing structure 41 is located between the A column inner plate upper section 111 and the A column reinforcing plate 21, which can firmly connect the A column inner plate upper section 111 and the A column reinforcing plate 21 together to form a more stable overall structure, which can significantly improve the strength and rigidity of the A column and enhance the impact resistance of the side of the vehicle body. The existence of the first sub-reinforcing structure 41 can also optimize the stress distribution inside the A column, which can effectively absorb and disperse impact energy in extreme conditions such as collision, preventing structural damage caused by stress concentration.
[0046] According to some embodiments of the utility model, as shown in Figure 1 The first sub-reinforcing structure 41 is fixed to the A column reinforcing plate 21, for example: the first sub-reinforcing structure 41 and the A column reinforcing plate 21 can be fixedly connected by welding, the first sub-reinforcing structure 41 and the A column reinforcing plate 21 can be fixedly connected by bolts, but the utility model is not limited to this, the first sub-reinforcing structure 41 and the A column reinforcing plate 21 can also be fixedly connected by other ways, as long as the first sub-reinforcing structure 41 is fixed to the A column reinforcing plate 21. The application is described by taking the first sub-reinforcing structure 41 and the A column reinforcing plate 21 as an example, the welding connection can ensure the stable connection between the first sub-reinforcing structure 41 and the A column reinforcing plate 21, the welding connection has good fatigue resistance, can withstand long-term alternating load without failure, the first sub-reinforcing structure 41 is fixed to the A column reinforcing plate 21 by welding, forming a more solid overall structure, which can significantly improve the strength and rigidity of the A column area and enhance the impact resistance of the vehicle body.
[0047] As an example of the present application, the first sub-reinforcing structure 41 can be configured as a hot gas expansion tube connected with the A-pillar reinforcing plate 21 through cold metal transfer welding, which can provide a high-strength connection effect, ensure the connection stability and reliability between the first sub-reinforcing structure 41 and the A-pillar reinforcing plate 21, and realize lightweight design through optimization design and material selection under the premise of ensuring strength, which is helpful to reduce the weight of the vehicle body, improve fuel economy and vehicle performance.
[0048] According to some embodiments of the present application, as shown in Figure 4 The first sub-reinforcing structure 41 and the A-pillar reinforcing plate 21 are welded to form a plurality of connection structures 22, and the plurality of connection structures 22 are arranged along the extension direction of the A-pillar reinforcing plate 21, and at least two adjacent connection structures 22 are staggered along the extension direction of the A-pillar reinforcing plate 21.
[0049] The first sub-reinforcing structure 41 and the A-pillar reinforcing plate 21 are welded to form a plurality of connection structures 22, and the plurality of connection structures 22 are arranged along the extension direction of the A-pillar reinforcing plate 21, and at least two adjacent connection structures 22 are staggered along the extension direction of the A-pillar reinforcing plate 21.
[0050] The plurality of connection structures 22 are arranged along the extension direction of the A-pillar reinforcing plate 21, which can effectively disperse stress and avoid structural damage caused by excessive stress on a single point, and at least two adjacent connection structures 22 are staggered along the extension direction of the A-pillar reinforcing plate 21, which can solve the problems of difficult installation and matching deformation of the hot gas expansion tube, and can also reduce stress concentration phenomenon, avoid structural failure due to excessive stress, help to prolong the service life of the vehicle body structure, and improve the durability of the vehicle.
[0051] According to some embodiments of the present application, as shown in Figure 1 The A-pillar inner plate 11 can include an A-pillar inner plate lower section 112, the first reinforcing structure 40 includes a second sub-reinforcing structure 42, and the second sub-reinforcing structure 42 is located between the A-pillar inner plate lower section 112 and the A-pillar reinforcing plate 21.
[0052] As an example of the present application, the second sub-reinforcing structure 42 can be a roll-formed tube, which can be made of HC820 / 1180DP high-strength steel. After the sheet metal is roll-formed, it is self-docking and forms a tubular structure through laser welding, which has high strength and rigidity. The second sub-reinforcing structure 42 is located between the lower section 112 of the A-pillar inner panel and the A-pillar reinforcing plate 21, which can effectively resist external impact and deformation, and improve the anti-collision ability of the A-pillar reinforcing plate.
[0053] The roll-forming process allows complex bending and forming operations on the tube to adapt to the needs of the vehicle body design. The roll-formed tube structure is relatively simple, has low production cost, and is relatively easy to repair and replace, which reduces maintenance cost and time.
[0054] According to some embodiments of the present application, as shown in Figure 1 and Figure 3 , the second sub-reinforcing structure 42 can be annular, and the second sub-reinforcing structure 42 extends along the extension direction of the lower section 112 of the A-pillar inner panel.
[0055] The annular structure has higher strength and rigidity, which can effectively resist external impact and deformation, and can also better disperse stress and avoid structural failure caused by stress concentration. The second sub-reinforcing structure 42 extends along the extension direction of the lower section 112 of the A-pillar inner panel, which can provide a larger connection area, thereby further enhancing the strength and rigidity of the region and improving the stability of the overall structure.
[0056] According to some embodiments of the present application, as shown in Figure 1 and Figure 3 , the second sub-reinforcing structure 42 is fixedly connected with the lower section 112 of the A-pillar inner panel and the A-pillar reinforcing plate 21, for example: the second sub-reinforcing structure 42 and the lower section 112 of the A-pillar inner panel and the A-pillar reinforcing plate 21 can be fixedly connected by bolts, or the second sub-reinforcing structure 42 and the lower section 112 of the A-pillar inner panel and the A-pillar reinforcing plate 21 can be fixedly connected by welding, as long as the second sub-reinforcing structure 42 and the lower section 112 of the A-pillar inner panel and the A-pillar reinforcing plate 21 are fixedly connected. Specifically, as shown in Figure 1 and Figure 3As shown, along the extension direction of the second sub-reinforcing structure 42, the second sub-reinforcing structure 42 can be formed with a plurality of threaded sleeves 60 arranged in a staggered manner, and the second sub-reinforcing structure 42 is fixedly connected with the A-pillar inner panel lower section 112 and the A-pillar reinforcing plate 21 through bolts, so as to ensure the connection strength between the second sub-reinforcing structure 42 and the A-pillar inner panel lower section 112 and the A-pillar reinforcing plate 21, and further ensure the fastening and stability of the connection. The threaded sleeves 60 arranged in a staggered manner can help to disperse the stress at the connection, avoid structural failure caused by stress concentration, further improve the strength and durability of the connection, and the connection mode of the threaded sleeves 60 and the bolts makes the installation process more simple, reduces the installation difficulty and time cost.
[0057] According to some embodiments of the present application, as shown in Figure 3 As shown, the second sub-reinforcing structure 42 can include a plurality of wall portions 421 connected in sequence, and at least two adjacent wall portions 421 are connected through an arc-shaped wall 422, and the radius of the circle on which the inner side wall of the arc-shaped wall 422 is located is greater than or equal to 3mm.
[0058] Among them, the second sub-reinforcing structure 42 can include a plurality of wall portions 421 connected in sequence, and at least two adjacent wall portions 421 are connected through an arc-shaped wall 422, and the radius of the circle on which the inner side wall of the arc-shaped wall 422 is located is greater than or equal to 3mm, for example: the radius of the circle on which the inner side wall of the arc-shaped wall 422 is located can be 3mm, 4mm, 5mm, 6mm and the like, but the present application is not limited thereto, the radius of the circle on which the inner side wall of the arc-shaped wall 422 is located can also be other values, as long as the radius of the circle on which the inner side wall of the arc-shaped wall 422 is located is greater than or equal to 3mm, the upper limit value of the radius of the circle on which the inner side wall of the arc-shaped wall 422 is located can be reasonably set according to the actual situation, in this way, the risk of cracking of the second sub-reinforcing structure 42 can be avoided.
[0059] The plurality of wall portions 421 are connected in sequence through the arc-shaped wall 422, forming a more solid overall structure, which can enhance the connection stability between the wall portions 421 and improve the carrying capacity of the overall structure, and the design of the arc-shaped wall 422 can effectively disperse stress and avoid structural failure caused by stress concentration. When the second sub-reinforcing structure 42 is subjected to external force, the arc-shaped wall 422 can absorb and disperse the impact energy, thereby improving the strength and rigidity of the second sub-reinforcing structure 42, and further improving the strength and rigidity of the side wall assembly 100.

The second reinforcing structure 50 can significantly improve the local strength and rigidity of the B-pillar area, help resist external impact and deformation, and improve the overall stability of the vehicle body. The second reinforcing structure 50 is fixedly connected with at least one of the B-pillar inner plate and the B-pillar reinforcing plate 23, for example, the second reinforcing structure 50 is fixedly connected with the B-pillar inner plate, or the second reinforcing structure 50 is fixedly connected with the B-pillar reinforcing plate 23, or the second reinforcing structure 50 is fixedly connected with both the B-pillar inner plate and the B-pillar reinforcing plate 23. As long as the second reinforcing structure 50 is fixedly connected with at least one of the B-pillar inner plate and the B-pillar reinforcing plate 23. As an example of the present application, the second reinforcing structure 50 and the B-pillar reinforcing plate 23 can be fixedly connected by spot welding. The second reinforcing structure 50 and the B-pillar reinforcing plate 23 can be effectively connected together, and the connection strength and stability between the two can be ensured, so that various complex loads and stresses can be borne during vehicle driving, and the overall strength and rigidity of the vehicle body can be improved.
[0062] Further, the side wall reinforcing plate 20 includes an A-pillar reinforcing plate 21, a B-pillar reinforcing plate 23, a C-pillar reinforcing plate 24, and a rocker outer plate 25. In manufacturing the side wall reinforcing plate 20, the A-pillar reinforcing plate 21, the B-pillar reinforcing plate 23, the C-pillar reinforcing plate 24, and the rocker outer plate 25 are first spliced by laser tailor welding, and then the B-pillar reinforcing plate 23 is spot-welded with the second reinforcing structure 50. After that, the side wall reinforcing plate 20 is heated and integrally formed in a hot stamping die. This can reduce the number and weight of lap joints of separate parts, improve the lightweight level of the vehicle body, optimize the force transmission path, improve the development cycle and production rhythm, and reduce the manufacturing cost of the vehicle while taking into account performance and lightweight.
[0063] After the side wall reinforcing plate 20 is integrally formed, the first reinforcing structure 40 and the second reinforcing structure 50 are assembled between the side wall reinforcing plate 20 and the side wall inner plate 10, and the side wall reinforcing plate 20 is connected with the side wall inner plate 10 and the side wall outer plate 30 to form a high-strength and lightweight side wall assembly 100. This can reduce the manufacturing cost of the vehicle while taking into account performance and lightweight.
[0064] To improve material utilization and reduce the weight of the part to a greater extent, when manufacturing the side wall reinforcement plate 20, appropriate laser welding positions can be selected, different regions can select appropriate thickness and strength according to their performance requirements, and the thickness of the manufacturing plate of the side wall reinforcement plate 20 can be set to be between 1.0-2.5mm, for example: the thickness of the manufacturing plate of the side wall reinforcement plate 20 can be 1.0mm, 2.5mm, etc. The strength can select 1500MPa-2000Mpa hot forming steel, for example: the strength of the manufacturing plate of the side wall reinforcement plate 20 can select 1500MPa, 2000Mpa hot forming steel, and the thickness of the plate of the second reinforcing structure 50 can be 1.2-2mm, for example: the thickness of the plate of the second reinforcing structure 50 can be 1.2mm, 2mm, etc. The manufacturing plate of the side wall reinforcement plate 20 can also select a bare plate (a steel plate without processing) or a plated plate.
[0065] As an example of the present application, the manufacturing plate of the side wall reinforcement plate 20 can be a bare plate, and a shot blasting process is added after the part is formed to remove the oxide film formed on the surface, but in order to ensure that the C-pillar reinforcement plate 24 has better part size after shot blasting, the thickness of the C-pillar reinforcement plate 24 can be greater than 1.2mm, thereby ensuring the size accuracy and strength of the side wall reinforcement plate 20, so that it can better withstand various loads and stresses, and help to improve the structural strength and stability of the vehicle, and improve the handling and safety of the vehicle.
