Detailed Implementation

[0036] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] like Figures 1-9 As shown, the vehicle side reinforcement structure of this embodiment includes a side door ring assembly, a door sill 3, and a floor beam 4.

[0038] Specifically, such as Figures 1-4 As shown, the side door ring assembly includes an integrated inner door ring 1 and an integrated outer door ring 2. The integrated outer door ring 2 includes an A-pillar outer panel 21, a B-pillar outer panel 22, a C-pillar outer panel 23, and an upper beam outer panel 24. The upper ends of the A-pillar outer panels 21, B-pillar outer panels 22, and C-pillar outer panels 23 are all connected to the upper beam outer panel 24, and the lower ends of the A-pillar outer panels 21, B-pillar outer panels 22, and C-pillar outer panels 23 are all connected to the sill 3. The integrated inner door ring 1 includes an A-pillar inner panel 11, a B-pillar inner panel 12, a C-pillar inner panel 13, and an upper beam inner panel 14. The upper ends of the A-pillar inner panels 11, B-pillar inner panels 12, and C-pillar inner panels 13 are all connected to the upper beam inner panel 14, and the lower ends of the A-pillar inner panels 11, B-pillar inner panels 12, and C-pillar inner panels 13 are all connected to the sill 3. The floor beam 4 is connected to the sill 3.

[0039] It is understandable that the outer A-pillar panel 21, outer B-pillar panel 22, outer C-pillar panel 23, and outer upper beam panel 24 form an integrated outer door ring 2, and the inner A-pillar panel 11, inner B-pillar panel 12, inner C-pillar panel 13, and inner upper beam panel 14 form an integrated inner door ring 1. Compared with the traditional side panel structure, this application simplifies the connection and forming of the A-pillar assembly, B-pillar assembly, C-pillar assembly, and upper beam assembly to the forming and connection of the inner and outer door rings. The integrated door ring reduces the number of structural components and production processes, and the integrated door ring can form a closed ring reinforcement structure after being connected with the sill 3, which improves the overall strength of the vehicle side panel and eliminates the weakening of the overall strength of the side panel by welding defects and welding failures.

[0040] The vehicle side wall reinforcing structure of the embodiment of the present application, the side wall door ring assembly comprises an integrated inner door ring 1 and an integrated outer door ring 2, and the integrated outer door ring 2 comprises an A-pillar outer plate 21, a B-pillar outer plate 22, a C-pillar outer plate 23 and an upper beam outer plate 24 connected with each other, the integrated inner door ring 1 comprises an A-pillar inner plate 11, a B-pillar inner plate 12 and a C-pillar inner plate 13 and an upper beam inner plate 14, and the integrated inner door ring 1 and the integrated outer door ring 2 are connected with a rocker 3, and a floor cross beam is connected with the rocker 3, so that the integrated door ring reduces the number of structural parts and production processes, and the integrated door ring can form a closed ring-shaped reinforcing structure after being connected with the rocker 3, thereby improving the overall strength of the vehicle side wall panel, eliminating the weakening of the overall strength of the side wall panel caused by welding defects and welding failure, and at the same time, the floor cross beam 4 can effectively support the rocker 3 to protect the battery and the passenger compartment.

[0041] Preferably, the rocker 3 is an integrated aluminum extrusion rocker 3, which can effectively crush and absorb collision energy.

[0042] Further, as shown in Figure 1 and Figure 2 , the upper beam outer plate 24 comprises a first outer plate segment and a second outer plate segment, the first outer plate segment is connected between the A-pillar outer plate 21 and the B-pillar outer plate 22, and the second outer plate segment is connected between the B-pillar outer plate 22 and the C-pillar outer plate 23, and the upper beam inner plate 14 comprises a first inner plate segment and a second inner plate segment, the first inner plate segment is connected between the A-pillar inner plate 11 and the B-pillar inner plate 12, and the second inner plate segment is connected between the B-pillar inner plate 12 and the C-pillar inner plate 13.

[0043] Further, as shown in Figure 3 , the top end of the B-pillar outer plate 22 is connected with a first adapter plate 25, and the first adapter plate 25 has a first side plate extending towards and connected with the first outer plate segment and a second side plate extending towards and connected with the second outer plate segment, and the first outer plate segment and the A-pillar outer plate 21 are connected through a second adapter plate 26 with a corner. Thus, the integrated outer door ring 2 is composed of the A-pillar outer plate 21, the first outer plate segment, the B-pillar outer plate 22, the second outer plate segment, the C-pillar outer plate 23, the first adapter plate 25 and the second adapter plate 26, and different parts can be selected from a plurality of thicknesses and material combinations to greatly improve the weight reduction opportunity. Preferably, laser welding is used between the parts.

[0044] Further, as shown in Figure 4 , the top end of the B-pillar inner plate 12 is connected with a third adapter plate 15, and the third adapter plate 15 has a second side plate extending towards and connected with the first inner plate segment and a third side plate extending towards and connected with the second inner plate segment, and the first inner plate segment and the A-pillar inner plate 11 are connected through a fourth adapter plate 16 with a corner.

[0045] Further, as shown in Figure 3As shown, the outer B-pillar panel 22 includes an outer B-pillar main plate connected to the first adapter plate 25 and an outer B-pillar bottom plate connected to the sill 3, and the outer B-pillar main plate and the outer B-pillar bottom plate are connected. The inner B-pillar panel 12 includes an inner B-pillar main plate connected to the third adapter plate 15 and an inner B-pillar bottom plate connected to the sill 3, and the inner B-pillar main plate and the inner B-pillar bottom plate are connected.

[0046] Therefore, the integrated inner door ring 1 is composed of multiple structural parts, including the A-pillar inner panel 11, the first inner panel segment, the B-pillar inner panel 12, the second inner panel segment, the C-pillar inner panel 13, the third transition plate 15, and the fourth transition plate 16. Different parts can be selected with various material thicknesses and combinations, greatly increasing the opportunity for weight reduction. Preferably, the various structural parts are laser welded together.

[0047] In some embodiments, such as Figure 1 As shown, the top surface of the threshold 3 is provided with a first threshold connecting plate 31 and a second threshold connecting plate 32 extending along its length and arranged at intervals. The first threshold connecting plate 31 connects between the inner panel 11 of the A-pillar and the inner panel 12 of the B-pillar, and the second threshold connecting plate 32 connects between the inner panel 12 of the B-pillar and the inner panel 13 of the C-pillar. Thus, the first threshold connecting plate 31, the inner panel 11 of the A-pillar, and the inner panel 12 of the B-pillar can form a closed loop structure, and the second threshold connecting plate 32, the inner panel 12 of the B-pillar, and the inner panel 13 of the C-pillar can also form a closed loop structure, further strengthening the structural strength of the integrated inner door ring 1.

[0048] Furthermore, such as Figure 6 As shown, the lower end of the B-pillar inner panel 12 has a B-pillar connecting plate 121 extending obliquely away from the B-pillar outer panel 22. The B-pillar connecting plate 121 is attached to and connected to the upper surface of the sill 3. The B-pillar connecting plate 121 and the floor beam 4 are connected by a beam connecting plate 5. One end of the beam connecting plate 5 is attached to and connected to the upper surface of the floor beam 4, and the other end is attached to and connected to the upper surface of the B-pillar connecting plate 121. Thus, the attachment of the B-pillar connecting plate 121 to the sill 3 increases the connection surface between the B-pillar inner panel 12 and the sill 3, thereby increasing the connection strength. The beam connecting plate 5 connects the B-pillar inner panel 12, the sill 3, and the floor beam 4 into a single unit, further improving the overall strength of the vehicle side panel.

[0049] Preferably, such as Figure 7 As shown, the integrated inner door ring 1 and / or the integrated outer door ring 2 are provided with a reinforcing structure.

[0050] Optionally, such as Figures 7-9 As shown, a reinforcing plate 7 is provided on the inner side of the outer panel 21 and / or the inner panel 11 of the A-pillar to improve the anti-collision strength of the A-pillar.

[0051] Optionally, there can be multiple reinforcing plates 7, arranged at intervals on the outer A-pillar panel 21 and the inner A-pillar panel 11. For example... Figure 8As shown, a set of reinforcing plates 7 can be arranged on the A-pillar inner panel at the bottom end and the middle region.

[0052] Optionally, as shown, reinforcing plates 7 are arranged on the inner side of the upper beam inner panel 14 and / or the upper beam outer panel 24. Figure 9

[0053] The vehicle of the embodiment of the present application comprises the vehicle side wall reinforcing structure of the above embodiment.

[0054] The vehicle of the embodiment of the present application, by adopting the above vehicle side wall reinforcing structure, the side wall door ring assembly comprises an integrated inner door ring 1 and an integrated outer door ring 2, and the integrated outer door ring 2 comprises an A-pillar outer panel 21, a B-pillar outer panel 22, a C-pillar outer panel 23 and an upper beam outer panel 24 connected together, and the integrated inner door ring 1 comprises an A-pillar inner panel 11, a B-pillar inner panel 12 and a C-pillar inner panel 13 and an upper beam inner panel 14, and the integrated inner door ring 1 and the integrated outer door ring 2 are connected with the rocker 3, and the floor cross beam is connected with the rocker 3, so that the integrated door ring reduces the number of structural parts and the production process, and after the integrated door ring is connected with the rocker 3, a closed ring-shaped reinforcing structure can be formed, the overall strength of the vehicle side wall panel is improved, the weakening of the overall strength of the side wall panel by welding defects and welding failure is eliminated, at the same time, the floor cross beam 4 can effectively support the rocker 3, protect the battery and the passenger compartment, and the vehicle has good crashworthiness.

[0055] The side wall door ring assembly manufacturing method of the embodiment of the present application, the side wall door ring assembly is according to the side wall door ring assembly of the above embodiment, and the method comprises:

[0057] It should be noted that taking the integrated outer door ring 2 as an example, if the A-pillar outer panel 21, the B-pillar outer panel 22 and the C-pillar outer panel 23 are directly connected with the upper beam outer panel 24 to form an integrated body, since the bottom end of the A-pillar outer panel 21 and the B-pillar outer panel 22 is open, and the bottom end of the B-pillar outer panel 22 and the C-pillar outer panel 23 is open, it is difficult to control the forming precision of the integrated outer door ring 2, thereby causing the integrated outer door ring 2 after forming to be not matched with the rocker 3.

[0058] ​To solve the above problems, the threshold imitation piece 6 is used to replace the threshold 3, the A-pillar outer plate 21, the B-pillar outer plate 22 and the C-pillar outer plate 23 are sequentially welded on the threshold imitation piece 6, and then the upper beam outer plate 24 is connected, so that the A-pillar outer plate 21, the threshold imitation piece 6 and the B-pillar outer plate 22 can form a closed structure, and the B-pillar outer plate 22 and the C-pillar outer plate 23 can form a closed structure, thereby ensuring the forming precision of the integrated outer door ring 2. Similarly, the forming process of the integrated inner door ring 1 can refer to the integrated outer door ring 2, and details are not repeated here.

[0059] Further, after the integrated outer door ring 2 and the integrated inner door ring 1 are formed, the threshold imitation piece 6 can be cut off, and then the threshold 3 is connected with the integrated outer door ring 2 and the integrated inner door ring 1 to form a side wall reinforcing structure.

[0060] The side wall door ring assembly manufacturing method of the embodiment of the application uses the threshold imitation piece 6 to replace the threshold 3, and sequentially welds each component based on the threshold imitation piece 6 to finally form the integrated inner door ring 1 and the integrated outer door ring 2, thereby reducing the number of structural components and production processes, and after the integrated door ring 1 is connected with the threshold 3, a closed ring reinforcing structure can be formed, the overall strength of the vehicle side wall plate is improved, the weakening of the overall strength of the side wall plate caused by welding defects and welding failure is eliminated, and the integrated door ring 1 remains a closed structure during forming, thereby ensuring the forming precision.
