Description

Technical Field

[0001] This invention relates to the field of vehicle structure, and more specifically to a side panel and a vehicle. Background Technology

[0002] In the development of new models, the position of the side panel 4a where it matches the A-pillar trim 5a and the roof trim 2a are crucial factors influencing the side panel structure design and stamping process. The structural design in this area significantly impacts material utilization, manufacturing processes, manufacturing steps, appearance matching, and surface quality. Under optimal styling and visibility conditions, the structural design of the parts plays a critical role in process control, cost, and mold debugging cycle. In previous vehicle development processes, cracking and material overlap in this area have consistently been challenging aspects of the overall vehicle development.

[0003] In models with A-pillar exterior trim 5a and roof trim 2a, to improve the poor surface quality at the sharp corners, the two exterior seam lines 31a and 32a converging at the sharp corners are designed to be as simple and smooth as possible to facilitate drawing and forming. Figure 1 As shown; to solve the problem of sidewall cracking at the sharp corner, the drawing depth at the sharp corner should be reduced as much as possible, or a shaping process should be added. Existing technical solutions, in order to reduce the stamping depth at the A-pillar sharp corner, require shortening the upper boundary of the windshield 1a downwards. The windshield boundary 12a and the roof trim 2a are butt-jointed, reducing the stamping depth. Although this solves the stamping problem of the side panel, it sacrifices the forward and upward visibility. The black edge 11a of the glass is often positioned relatively low, and the width of the black edge 6a is shown in the figure. Figure 1 As shown.

[0004] Existing technologies cannot simultaneously achieve both aesthetic appeal and optimal top field of vision. Therefore, it is necessary to provide a solution that can achieve both good aesthetic appeal and optimal top field of vision. Summary of the Invention

[0005] In order to simultaneously achieve both aesthetic appeal and optimal visibility, this invention proposes a side panel and vehicle, which is specifically implemented using the following technical solution.

[0006] The present invention provides a side panel, comprising a first panel, a second panel, a third panel, a first connecting plate, a second connecting plate, and a third connecting plate, wherein the first connecting plate, the second connecting plate, and the third connecting plate are connected to each other, the first connecting plate is connected to the first panel and the second panel respectively, the second connecting plate is connected to the first panel and the third panel respectively, and the third connecting plate is connected to the second panel and the third panel respectively.

[0007] The first plate has a first arc-shaped edge, a second arc-shaped edge, and a straight edge. A first spherical rounded corner is formed between the first arc-shaped edge and the second arc-shaped edge, and a second spherical rounded corner is formed between the first arc-shaped edge and the straight edge. The first arc-shaped edge and the straight edge are used to abut against the top cover panel, and the second arc-shaped edge is used to abut against the outer panel.

[0008] The second plate is used to connect the windshield and the roof trim panel;

[0009] The third plate is used to connect the exterior trim panel.

[0010] A further improvement of the side panel provided by the present invention is that the second panel is provided with a first step, a second step and a third step, the first step being used to support the top cover trim panel, the second step being used to support the windshield, and the third step being used to connect the glass adhesive layer.

[0011] A further improvement of the side panel provided by the present invention is that the distance between the first step and the first plate is equal to the sum of the thickness of the top cover trim and the length of the preset safety gap;

[0012] The distance between the second step and the first plate is equal to the sum of the thickness of the top cover trim, the thickness of the windshield, and the length of the preset safety gap;

[0013] The distance between the third step and the second step is equal to the difference between the thickness of the glass adhesive layer and the length of the preset safety gap.

[0014] A further improvement of the side panel provided by the present invention is that the first connecting plate is provided with oblique triangular ribs.

[0015] A further improvement of the side panel provided by the present invention is that the length of the preset safety gap is greater than 3mm;

[0016] The distance between the oblique triangular rib and the windshield at the end near the first spherical rounded corner is greater than 3mm, and the distance between the oblique triangular rib and the top cover trim panel at the end near the second spherical rounded corner is not less than 3mm and not more than 5mm.

[0017] A further improvement of the side panel provided by the present invention is that the first included angle between the oblique triangular rib and the stamping direction is not less than 35°.

[0018] A further improvement of the side panel provided by the present invention is that the oblique triangular rib is trumpet-shaped, and the width of the oblique triangular rib at the end near the second spherical rounded corner is smaller than the width of the oblique triangular rib at the end near the first spherical rounded corner.

[0019] A further improvement of the side panel provided by the present invention is that the second included angle between the first arcuate ridge and the second arcuate ridge is greater than 60°, and the third included angle between the first arcuate ridge and the straight ridge is greater than 135°.

[0020] A further improvement of the side panel provided by the present invention is that the fourth included angle between the second arcuate ridge and the stamping direction is equal to 3°.

[0021] A further improvement of the side panel provided by the present invention is that the width of the first step on the side near the second spherical rounded corner is equal to 3 mm;

[0022] The first step has a first weld point, and the width of the first step in the direction passing through the first weld point is equal to 16mm.

[0023] A further improvement of the side panel provided by the present invention is that the third panel is provided with wrinkle-absorbing ribs.

[0024] A further improvement of the side panel provided by the present invention is that the depth of the wrinkle-absorbing rib is equal to 2mm.

[0025] In addition, the present invention also provides a vehicle including an exterior trim panel, a roof trim panel, a windshield, and a side panel as described above; a first panel of the side panel abuts against the roof trim panel and the exterior trim panel, a second panel of the side panel is connected to the windshield and the roof trim panel respectively, and a third panel of the side panel is connected to the exterior trim panel.

[0026] This invention optimizes and improves the structure of the side panel, which can overcome the adverse effects of the increased stamping depth and more complex appearance lines on the two sharp corners, while reducing manufacturing costs and stamping processes.

[0027] This invention, while taking into account both aesthetic appeal and optimal visibility, solves the problem of poor surface quality of the side panel in the assembly areas of the roof trim and A-pillar trim; it also solves the problem of cracking that easily occurs in the assembly areas of the side panel in the roof trim and A-pillar trim; it solves the problem of overlapping and wrinkling of the side walls and welding edges of the side panel in the assembly areas of the roof trim and A-pillar trim; and it can also optimize the number of processes for the side panel in this area.

[0028] The ingenious spherical corner design at the two sharp angles and the reduced drawing depth in the curved section of this invention allow for greater freedom in styling choices and designs, rather than being limited to simple straight-line fits. In terms of solving molding cracking, this invention reduces the molding process in that area to a single step and also allows the upper boundary of the windshield to be concealed within the roof trim panel, thereby increasing the forward and upward visibility angle.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] like Figure 1 As shown, in the prior art, the boundary 12a of the windshield and the boundary of the roof trim 2b are butt-jointed with no overlap; the black edge 11a of the glass is often positioned relatively low, resulting in poor upward visibility. In order to simultaneously achieve both aesthetic appeal and optimal upward visibility, this invention provides a side panel and a vehicle.

[0038] Example 1:

[0039] Combination Figures 2 to 6As shown, this embodiment 1 provides a side panel 4b, including a first panel 101, a second panel 102, a third panel 103, a first connecting plate 111, a second connecting plate 112, and a third connecting plate 113. The first connecting plate 111, the second connecting plate 112, and the third connecting plate 113 are connected to each other. The first connecting plate 111 is connected to the first panel 101 and the second panel 102 respectively. The second connecting plate 112 is connected to the first panel 101 and the third panel 103 respectively. The third connecting plate 113 is connected to the second panel 102 and the third panel 103 respectively.

[0040] The first plate 101 is provided with a first arc-shaped edge 31b, a second arc-shaped edge 32b and a straight edge 33b. A first spherical rounded corner 82 is formed between the first arc-shaped edge 31b and the second arc-shaped edge 32b, and a second spherical rounded corner 81 is formed between the first arc-shaped edge 31b and the straight edge 33b. The first arc-shaped edge 31b and the straight edge 33b are used to abut against the top cover panel 2b, and the second arc-shaped edge 32b is used to abut against the outer panel 5b.

[0041] The second plate 102 is used to connect the windshield 1b and the roof trim 2b;

[0042] The third plate 103 is used to connect the exterior trim panel 5b.

[0043] When the upper boundary 12b of the windshield 1b extends to below the roof trim 2b, the width 6b of the black border 11b can be reduced, thereby maximizing the optimization of the forward and upward visibility angle. However, this requires increasing the stamping depth of the side panel 4b where it matches the A-pillar trim 5b and the roof trim 2b. In addition, a more complex curved exterior edge effect is also needed to balance the styling effect.

[0044] In this embodiment 1, the outer trim panel 5b refers to the A-pillar outer trim panel 5b, and the second panel 102 of the side panel 4b can be used to connect the windshield 1b and provide support for the windshield 1b to extend to the bottom of the roof trim panel 2b; a first spherical rounded corner 82 and a second spherical rounded corner 81 are respectively provided at the two sharp corners of the first panel 101. The two sharp corners are sphericalized to form the first spherical rounded corner 82 and the second spherical rounded corner 81, which can protect the sharp corners from cracking during the stamping process and overcome the influence of complex appearance lines on the outer surface quality; and the reasonable design of the size of the spherical rounded corners can protect the rounded corners from cracking during forming.

[0045] Furthermore, the second plate 102 is provided with a first step 71, a second step 72 and a third step 73. The first step 71 is used to support the top cover trim 2b, the second step 72 is used to support the windshield 1b and the third step 73 is used to connect the glass adhesive layer.

[0046] The drawing depth at the first spherical fillet 82 is relatively deep. In order to prevent the first spherical fillet 82 from cracking during the drawing process, this embodiment 1 designs a first step 71, a second step 72 and a third step 73 to divide the depth difference into three steps. The second plate 102 is designed to be formed in a three-step manner, thereby protecting the first spherical fillet 82 from cracking during the drawing process. This allows the area to be drawn in one step, solving the cracking problem here.

[0047] Furthermore, the distance H1 between the first step 71 and the first plate 101 is equal to the sum of the thickness of the top cover trim 2b and the length of the preset safety gap H3; the distance H2 between the second step 72 and the first plate 101 is equal to the sum of the thickness of the top cover trim 2b, the thickness of the windshield 1b, and the length of the preset safety gap H3; the distance between the third step 73 and the second step 72 is equal to the difference between the thickness of the glass adhesive layer and the length of the preset safety gap H3. In this embodiment 1, the depths of the first step 71, the second step 72, and the third step 73 gradually transition and deepen, alleviating the problem of stamping cracking caused by drastic depth changes.

[0048] Furthermore, the first connecting plate 111 is provided with a diagonal triangular rib 92.

[0049] In this embodiment 1, by setting oblique triangular ribs 92 in the first connecting plate 111, the drawing depth can be reduced, the adverse effects of drawing on the side appearance can be mitigated, the forming at the first arc-shaped ridge 31b can be protected, and in particular, the side wall in this area can be protected from cracking during drawing, thus solving the problem of cracking of the outer side plate 4b after the drawing depth is increased.

[0050] Furthermore, the length of the preset safety gap H3 is greater than 3mm; the distance between the end of the oblique triangular rib 92 near the first spherical rounded corner 82 and the windshield 1b is greater than 3mm, and the distance between the end of the oblique triangular rib 92 near the second spherical rounded corner 81 and the top cover trim 2b is not less than 3mm and not more than 5mm. Based on this, the angle θ3 between the oblique triangular rib 92 and the stamping direction is maximized as much as possible; the larger the angle θ3, the better for forming.

[0051] Furthermore, the first included angle θ3 between the oblique triangular rib 92 and the stamping direction is not less than 35°.

[0052] Furthermore, the oblique triangular rib 92 is trumpet-shaped, and the width of the oblique triangular rib 92 at the end near the second spherical rounded corner 81 is smaller than the width of the oblique triangular rib 92 at the end near the first spherical rounded corner 82.

[0053] In this embodiment 1, the oblique triangular rib 92 is designed in a trumpet shape. The width of the oblique triangular rib 92 at the end near the second spherical fillet 81 is smaller than the width of the oblique triangular rib 92 at the end near the first spherical fillet 82. That is, the oblique triangular rib 92 gradually increases in size from the end near the second spherical fillet 81 to the end near the first spherical fillet 82. In other words, the upper boundary line 10 of the oblique triangular rib 92 gradually rises from the fillet R1 at the root of the first step 71, transitioning smoothly until it approaches the outer surface of the first plate 101. In this embodiment 1, under the condition of continuously increasing depth, by gradually increasing the size of the oblique triangular rib 92, the drawing line L2 ( Figure 4 The length of the dotted line (in the diagram) is always maintained within a uniform range, which helps to improve the appearance quality of the drawn and stamped parts and further protects the sidewall of the first arc-shaped ridge 31b from cracking during the drawing process. The drawing line length refers to the distance the material flows during the stamping and drawing process; the shorter the distance, the better. In this embodiment 1, the first arc-shaped ridge 31b, the second arc-shaped ridge 32b, and the straight ridge 33b are all rounded. Figure 4 R2 is the rounded corner of the first arc-shaped edge 31b, and H4 is the straight segment that matches the top cover trim 2b.

[0054] Furthermore, the second included angle θ2 between the first arcuate edge 31b and the second arcuate edge 32b is greater than 60°, and the third included angle θ1 between the first arcuate edge 31b and the straight edge 33b is greater than 135°.

[0055] The first spherical fillet 82 and the second spherical fillet 81 are cosmetic fillets, so the spherical fillets should not be too large and should be aesthetically pleasing. Furthermore, the second included angle θ2 and the third included angle θ1 need to be limited. Too small an included angle not only makes molding difficult but also severely impacts the appearance quality. Therefore, the recommended value for the second included angle θ2 between the first arc-shaped edge 31b and the second arc-shaped edge 32b is greater than 60°, and the recommended value for the third included angle θ1 between the first arc-shaped edge 31b and the straight edge 33b is greater than 135°, facilitating molding and ensuring good appearance quality.

[0056] Furthermore, the fourth included angle θ4 between the second arc-shaped ridge 32b and the stamping direction is equal to 3°.

[0057] To reduce unnecessary stamping processes, in this embodiment 1, the draft angle (fourth included angle θ4) at the second arc-shaped ridge 32b is designed as a positive angle in the Z direction, specifically Z direction + 3°. That is, the fourth included angle θ4 between the second arc-shaped ridge 32b and the stamping direction is equal to 3°, thus saving the forming process at this point. The value of the fourth included angle θ4 matches the A-pillar exterior trim panel 5b.

[0058] Furthermore, the width of the first step 71 on the side near the second spherical fillet 81 is equal to 3mm; the first step 71 is provided with a first solder point P3, and the width of the first step 71 in the direction passing through the first solder point P3 is equal to 16mm.

[0059] In this type of structure, wrinkling often occurs on the flange surface around sharp corners. To solve the wrinkling problem, in this embodiment 1, the cutting edge line L3 (i.e., boundary line) of the second plate 102 can be adjusted to shorten the width of the first step 71 on the side near the second spherical fillet 81 as much as possible. Preferably, the width on the side near the second spherical fillet 81 is equal to 3mm, thereby removing the wrinkled part.

[0060] In this embodiment 1, the first step 71 has a first weld point P3 for connecting the outer side panel 4b and the top cover trim panel 2b; the third step 73 has a second weld point P1 for connecting the outer side panel 4b and the A-pillar trim panel 5b; the A-pillar trim panel 5b has a third weld point P2 for connecting the A-pillar trim panel 5b and the A-pillar inner panel; and the outer side panel 4b also has a fourth weld point P4 for connecting the outer side panel 4b and the top cover trim panel 2b. In this embodiment 1, considering that the distance between the second weld point P1 and the fourth weld point P4 is too long, the width at the first weld point P3 is widened, so that the width of the first step 71 in the direction passing through the first weld point P3 is equal to 16mm.

[0061] Furthermore, the third plate 103 is provided with wrinkle-absorbing ribs 91. In this embodiment 1, wrinkle-absorbing ribs 91 (concave ribs) are designed according to actual needs to solve the problems of wrinkling and stacking of parts; furthermore, the depth of wrinkle-absorbing ribs 91 is equal to 2mm to avoid the wrinkle-absorbing ribs 91 being too deep and causing the first spherical fillet 82 to crack. Figure 5 In the middle, H6 represents the depth of the wrinkle-reducing rib 91, and H5 represents the forming depth on one side of the second arc-shaped ridge 32b.

[0062] This invention optimizes and improves the structure of the outer side panel 4b, which can overcome the adverse effects of the deeper stamping depth and more complex appearance lines on the two sharp corners, while reducing manufacturing costs and stamping processes.

[0063] This invention, while balancing aesthetic appeal and optimal upper field of vision, solves the problems of poor surface quality of the side panel 4b in the component areas of the roof trim 2b and A-pillar trim 5b; it also solves the problem of easy cracking of the side panel 4b in the component areas of the roof trim 2b and A-pillar trim 5b; it solves the problem of material overlap and wrinkling on the side walls and welding edges of the side panel 4b in the component areas of the roof trim 2b and A-pillar trim 5b; and it can also optimize the number of processes for the side panel 4b in this area.

[0064] The ingenious spherical corner design at the two sharp angles and the reduced drawing depth in the curved section of this invention allow for greater freedom in styling choices and designs, rather than being limited to simple straight-line fits. In terms of solving molding cracking, this invention reduces the molding process in that area to a single step and also allows the upper boundary 12b of the windshield 1b to be concealed within the roof trim 2b, thereby increasing the forward and upward visibility angle.

[0065] Example 2:

[0066] This embodiment 2 provides a vehicle including an exterior trim panel 5b, a roof trim panel 2b, a windshield 1b, and a side panel 4b as in embodiment 1; the first panel 101 of the side panel 4b abuts against the roof trim panel 2b and the exterior trim panel 5b, the second panel 102 of the side panel 4b is connected to the windshield 1b and the roof trim panel 2b respectively, and the third panel 103 of the side panel 4b is connected to the exterior trim panel 5b.

[0067] In this embodiment 2, the second plate 102 of the side outer panel 4b connects to the windshield 1b, providing support for the windshield 1b to extend to the bottom of the roof trim 2b. A first spherical rounded corner 82 and a second spherical rounded corner 81 are respectively provided at the two sharp corners of the first plate 101. Spherical treatment of the two sharp corners to form the first spherical rounded corner 82 and the second spherical rounded corner 81 protects the sharp corners from cracking during stamping, overcoming the influence of complex appearance lines on the outer surface quality. Furthermore, the reasonable design of the spherical rounded corner dimensions protects the rounded corners from cracking during forming. This overcomes problems such as stamping cracking, wrinkling, and poor surface finish caused by increasing the stamping depth of the side outer panel 4b at the matching point with the A-pillar outer trim 5b and the roof trim 2b. In this embodiment 2, the upper boundary 12b of the windshield 1b extends to the bottom of the roof trim 2b, maximizing the optimization of the forward and upward viewing angle. This embodiment 2 also incorporates more complex curved appearance lines to balance aesthetic appeal.

[0068] This invention, while balancing aesthetic appeal and optimal upper field of vision, solves the problems of poor surface quality of the side panel 4b in the component areas of the roof trim 2b and A-pillar trim 5b; it also solves the problem of easy cracking of the side panel 4b in the component areas of the roof trim 2b and A-pillar trim 5b; it solves the problem of material overlap and wrinkling on the side walls and welding edges of the side panel 4b in the component areas of the roof trim 2b and A-pillar trim 5b; and it can also optimize the number of processes for the side panel 4b in this area.

[0069] The ingenious spherical corner design at the two sharp angles and the reduced drawing depth in the curved section of this invention allow for greater freedom in styling choices and designs, rather than being limited to simple straight-line fits. In terms of solving molding cracking, this invention reduces the molding process in that area to a single step and also allows the upper boundary 12b of the windshield 1b to be concealed within the roof trim 2b, thereby increasing the forward and upward visibility angle.

[0070] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
