Description

Technical Field

[0001] This invention belongs to the field of vehicles, and in particular relates to a front bulkhead assembly, a vehicle, and a method for manufacturing the front bulkhead assembly. Background Technology

[0002] The front bulkhead is the main isolation component between the engine compartment and the passenger compartment, and it has the functions of sound insulation, vibration reduction, and heat insulation.

[0003] Conventional one-piece front bulkheads have a large drawing depth, which leads to many stamping cracks. They require the use of deep-drawing steel with better drawing performance and higher cost. Furthermore, trimming and punching require the use of oblique wedge dies, which have complex die structures and low material utilization in stamping, resulting in high production costs per piece.

[0004] An existing split-type front bulkhead assembly includes an upper front bulkhead, a left front bulkhead, a right front bulkhead, and a lower front bulkhead. The lower ends of the left and right sides of the upper front bulkhead are fixedly connected to the upper ends of the left and right front bulkheads, respectively. The lower middle part of the upper front bulkhead is fixedly connected to the upper end of the lower front bulkhead. The left and right ends of the lower front bulkhead are fixedly connected to the lower right part of the left front bulkhead, the left part of the right front bulkhead, and the lower part of the right front bulkhead, respectively. This split-type front bulkhead assembly divides the front bulkhead into four plates: the upper front bulkhead, the left front bulkhead, the right front bulkhead, and the lower front bulkhead. The left and right wheel arch clearance parts are respectively located on the left and right front bulkheads, which reduces the difficulty of stamping and forming. However, the entire front bulkhead is welded together from four plates, which involves a complex welding process and high cost. Summary of the Invention

[0006] To solve the above-mentioned technical problems, embodiments of the present invention provide a front bulkhead assembly, including an upper front bulkhead and a lower front bulkhead;

[0008] The upper part of the lower front panel is connected to the lower part of the upper panel body and the lower part of the wheel arch clearance part.

[0009] Optionally, it also includes a front bulkhead reinforcing beam extending in the left-right direction; the front bulkhead reinforcing beam is respectively connected to the upper front bulkhead and the lower front bulkhead.

[0010] Optionally, the upper part of the middle section of the front bulkhead reinforcing beam is connected to the front side of the upper plate body, and the lower part is connected to the front side of the lower front bulkhead plate; the two ends of the front bulkhead reinforcing beam are respectively connected to the front side of the corresponding wheel arch clearance portion.

[0011] Optionally, the front upper panel further includes a lower connecting edge, which is located at the lower edge of the upper panel body;

[0012] The lower front panel includes a lower panel body and a connecting edge on the upper side of the lower panel body; the middle section of the connecting edge on the lower side overlaps the lower connecting edge of the upper panel, and the two ends overlap the lower edge of the wheel arch clearance portion.

[0013] Optionally, the front bulkhead reinforcing beam includes a beam body, an upper beam connecting edge connected to the upper part of the beam body, and a lower beam connecting edge connected to the lower part of the beam body;

[0014] The middle section of the connecting edge on the beam is connected to the upper plate body, and both ends are connected to the wheel cover clearance part;

[0015] The two ends of the lower connecting edge of the beam are connected to the wheel cover clearance part.

[0016] Optionally, the connecting edge of the beam is welded to the front side of the upper plate body and the front side of the wheel cover clearance part;

[0017] The middle sections of the lower connecting edge of the beam, the lower connecting edge of the upper plate, and the upper connecting edge of the lower plate are stacked and welded from front to back; the two ends of the lower connecting edge of the beam are welded to the front side of the wheel cover clearance part.

[0018] The two ends of the connecting edge on the lower plate are welded to the rear side of the wheel arch clearance part.

[0019] Optionally, the middle section of the connecting edge on the beam and the upper plate body, the two ends of the connecting edge on the beam and the wheel cover clearance part, and the wheel cover clearance part and the two ends of the connecting edge on the lower plate are all connected by two layers of spot welding.

[0020] The middle sections of the connecting edge on the lower plate, the lower connecting edge on the upper plate, and the lower connecting edge on the beam are connected by three layers of spot welding.

[0021] Optionally, a force transmission cavity is formed between the beam body and the upper plate body, and between the beam body and the wheel cover clearance portion.

[0022] Optionally, the thickness of the lower front panel is less than the thickness of the upper front panel.

[0023] On the other hand, the present invention also provides a vehicle including the aforementioned front bulkhead assembly.

[0024] Compared with the prior art, the front bulkhead assembly and vehicle provided in this embodiment of the invention divide the front bulkhead assembly into two parts—upper front bulkhead and lower front bulkhead. The wheel arch clearance portion is set on the upper front bulkhead, which has a simple structure and is conducive to simplifying processing and assembly. On the raw material plate used to process the upper front bulkhead, the rib groove structure corresponding to the area of ​​the upper plate body and the area corresponding to the wheel arch clearance portion can be lightly machined, and then the area corresponding to the wheel arch clearance portion can be folded back to reduce the processing depth of the wheel arch clearance portion. This is conducive to simplifying the mold and improving the material utilization rate, thus reducing the cost.

[0025] On the other hand, the present invention also provides a method for manufacturing the aforementioned front bulkhead assembly, comprising the following steps:

[0026] Manufacturing the upper front fascia panel; the manufacturing steps of the upper front fascia panel include:

[0027] The front upper panel is processed into a process component. The area on the front upper panel process component corresponding to the wheel arch clearance part is in an unfolded state. The area on the front upper panel process component corresponding to the upper panel body has a first rib groove structure, and the area on the front upper panel process component corresponding to the wheel arch clearance part has a second rib groove structure.

[0028] The front upper panel process component is precision machined to shape the second rib groove structure into place and to fold and arch the wheel cover clearance part on the front upper panel into place.

[0029] Manufacture the aforementioned lower front panel;

[0030] Connect the upper front panel and the lower front panel.

[0031] Optionally, the step of processing the front upper panel process part includes: stamping a steel plate with a first stamping die, drawing the first rib groove structure and the second rib groove structure on the steel plate to obtain the front upper panel process part, and the first rib groove structure is in the formed state.

[0032] Optionally, the finishing process of the front upper panel process component includes: stamping the front upper panel process component with a second stamping die, shaping the second rib groove structure into place, folding and arching the part of the front upper panel process component corresponding to the wheel arch avoidance part into place, and flanging the perimeter of the front upper panel into place.

[0033] The manufacturing method of the front bulkhead assembly provided in this embodiment of the invention avoids directly stamping the wheel cover clearance part on the steel plate in one sequence compared with the prior art. Instead, the upper front bulkhead plate and the lower front bulkhead plate are manufactured separately, and then the upper front bulkhead plate and the lower front bulkhead plate are connected. When manufacturing the upper front bulkhead plate, the area on the upper front bulkhead plate process component corresponding to the wheel cover clearance part is in an unfolded state, and then the wheel cover clearance part is folded up. This can reduce the processing depth of the wheel cover clearance part, reduce the waste area, simplify the mold and improve the material utilization rate, reduce the number of processes, and reduce costs.

[0051] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0052] The directions in this application are consistent with the directions when a vehicle is driving normally: the front-to-back direction is the x-direction, which is longitudinal; the left-to-right direction is the y-direction, which is lateral; and the up-and-down direction is the z-direction, which is vertical.

[0053] like Figures 1 to 7 As shown, the front bulkhead assembly provided in this embodiment of the invention includes an upper front bulkhead 1 and a lower front bulkhead 2;

[0054] The front upper panel 1 includes an upper panel body 11 and wheel arch clearance portions 12 integrally disposed at the left and right ends of the upper panel body 11, so that the structure consisting of the upper panel body 11, the wheel arch clearance portion 12 disposed at the left end of the upper panel body 11 and the wheel arch clearance portion 12 disposed at the right end of the upper panel body 11 is an integral structure; the wheel arch clearance portion 12 arches backward relative to the upper panel body 11.

[0055] The upper part of the lower front panel 2 is connected to the lower part of the upper panel body 11 and the lower part of the wheel arch clearance part 12.

[0056] The front bulkhead assembly provided in this embodiment of the invention, compared with the prior art, divides the front bulkhead assembly into upper and lower parts—upper front bulkhead 1 and lower front bulkhead 2. The wheel arch clearance portion 12 is integrally set on the upper front bulkhead 1. The structure is simple and facilitates simplified processing and assembly. Rib groove structures corresponding to the area of ​​the upper bulkhead body 11 and the area corresponding to the wheel arch clearance portion 12 can be shallowly machined on the raw material plate used for processing the upper front bulkhead 1 (at this time, the upper front bulkhead is a process component, and the wheel arch clearance portion 12 is in a flattened state relative to the finished upper front bulkhead 1, such as...). Figure 8 As shown, Figure 8The arrows in the diagram indicate the folding direction of the front upper panel process component relative to the finished front upper panel 1. The area indicated by 12a is a schematic diagram of the wheel cover clearance part 12 in a folded state. Folding the area corresponding to the wheel cover clearance part 12 back can reduce the processing depth of the wheel cover clearance part 12, which is beneficial for simplifying the mold, improving material utilization, and reducing costs.

[0057] In one embodiment, such as Figures 1 to 4 As shown, it also includes a front bulkhead reinforcing beam 3 extending in the left-right direction; the front bulkhead reinforcing beam 3 is connected to the upper front bulkhead 1 and the lower front bulkhead 2 respectively. The front bulkhead reinforcing beam 3 increases the connection strength between the upper front bulkhead 1 and the lower front bulkhead 2, avoids collision tearing between the upper front bulkhead 1 and the lower front bulkhead 2, and improves the collision safety performance of the vehicle body structure.

[0058] Specifically, the upper front panel 1 and the lower front panel 2 are made of steel plates, and the front panel reinforcing beam 3 is made of hot-formed steel or ultra-high-strength steel.

[0059] Preferably, the upper part of the middle section of the front bulkhead reinforcing beam 3 is connected to the front side of the upper plate body 11, and the lower part is connected to the front side of the lower front bulkhead plate 2; both ends of the front bulkhead reinforcing beam 3 are respectively connected to the front side of the corresponding wheel arch avoidance parts 12. The structure is simple, which can reduce the width of the front bulkhead reinforcing beam 3 and reliably increase the connection strength between the upper front bulkhead plate 1 and the lower front bulkhead plate 2, avoid collision tearing between the upper front bulkhead plate 1 and the lower front bulkhead plate 2, and improve the collision safety performance of the vehicle body structure.

[0060] In one embodiment, such as Figure 3 and Figure 4 As shown, the front upper panel 1 also includes an upper panel lower connecting edge 13, which is located at the lower edge of the upper panel body 11.

[0061] The lower front panel 2 includes a lower panel body 21 and a lower upper connecting edge 22 located on the upper edge of the lower panel body 21. The middle section of the lower upper connecting edge 22 overlaps with the lower connecting edge 13 of the upper panel, and both ends overlap with the lower edge of the wheel arch clearance portion 12. By providing the lower connecting edge 13 of the upper panel and the upper connecting edge 22 of the lower panel, a reliable connection between the upper front panel 1 and the lower front panel 2 is achieved through the lower upper connecting edge 22 overlapping the lower connecting edge 13 of the upper panel and the wheel arch clearance portion 12.

[0062] In one embodiment, such as Figure 3 and Figure 4 As shown, the front bulkhead reinforcing beam 3 includes a beam body 31, an upper beam connecting edge 32 connected to the upper part of the beam body 31, and a lower beam connecting edge 33 connected to the lower part of the beam body 31.

[0063] The middle section of the upper connecting edge 32 is connected to the upper plate body 11, and the two ends of the upper connecting edge 32 are connected to the wheel cover clearance part 12.

[0064] The upper panel lower connecting edge 13 is connected to the middle section of the lower panel upper connecting edge 22 and the middle section of the beam lower connecting edge 33 respectively; the two ends of the beam lower connecting edge 33 are connected to the wheel arch avoidance part 12. This facilitates the connection of the front bulkhead reinforcing beam 3 to the front bulkhead upper panel 1 and the front bulkhead lower panel 2, increases the connection strength between the front bulkhead upper panel 1 and the front bulkhead lower panel 2, avoids collision tearing between the front bulkhead upper panel 1 and the front bulkhead lower panel 2, and improves the collision safety performance of the vehicle body structure.

[0065] Specifically, the upper connecting edge 32 of the beam is welded to the front side of the upper plate body 11 and the front side of the wheel cover clearance part 12;

[0066] The middle sections of the lower connecting edge 33 of the beam, the middle sections of the lower connecting edge 13 of the upper plate, and the middle sections of the upper connecting edge 22 of the lower plate are stacked from front to back and connected by welding; the two ends of the lower connecting edge 33 of the beam are welded to the front side of the corresponding wheel cover clearance part 12.

[0067] The two ends of the connecting edge 22 on the lower plate are welded to the rear side of the wheel arch clearance part 12. This facilitates the assembly of the upper front panel 1, the lower front panel 2, and the front panel reinforcing beam 3, and ensures the connection strength of the three components.

[0068] In one embodiment, such as Figure 3 and Figure 4 As shown, the middle section of the upper connecting edge 32 of the beam is connected to the upper plate body 11, the two ends of the upper connecting edge 32 of the beam are connected to the wheel cover clearance part 12, and the wheel cover clearance part 12 is connected to the two ends of the lower plate connecting edge 22 by two layers of spot welding.

[0069] The middle sections of the connecting edge 22 on the lower plate, the lower connecting edge 13 on the upper plate, and the middle sections of the lower connecting edge 33 on the beam are connected by three layers of spot welding. This simplifies the assembly process of the upper front panel 1, the lower front panel 2, and the front panel reinforcing beam 3, and is less expensive than the front panel assembly assembled by laser welding.

[0070] Preferably, the upper connecting edge 13 and the lower connecting edge 22 are connected by spot welding adhesive, and the wheel arch clearance part 12 and the lower connecting edge 22 are connected by spot welding adhesive. The spot welding adhesive plays a sealing and reinforcing role between the upper front panel 1 and the lower front panel 2.

[0071] In one embodiment, such as Figure 3 As shown, a force transmission cavity 4 is formed between the beam body 31 and the upper plate body 11, and between the beam body 31 and the wheel cover clearance part 12. The force transmission cavity 4 is conducive to stress dispersion and better avoids collision tearing between the upper front plate 1 and the lower front plate 2.

[0072] In one embodiment, the thickness of the lower front panel 2 is less than the thickness of the upper front panel 1. The lower front panel 2 and the upper front panel 1 are two parts, so different thicknesses can be used. Reducing the thickness of the lower front panel 2 is beneficial for vehicle body lightweighting and cost reduction.

[0073] In one embodiment, the boundary line between the wheel arch clearance portion 12 and the upper plate body 11 is a straight line or nearly a straight line when projected in the front-rear direction. This makes it easy to fold the wheel arch clearance portion 12 relative to the upper plate body 11, which simplifies the manufacturing process. Figure 5 The area enclosed by dashed boxes A and B serves as the wheel cover clearance part 12. During processing, the wheel cover clearance part 12 is folded up along the straight edges A1 and B1. The process is simple, and a certain design deviation is allowed during actual processing. The boundary line between the wheel cover clearance part 12 and the upper plate body 11 should be close to a straight line.

[0074] On the other hand, the present invention also provides a vehicle including the aforementioned front bulkhead assembly.

[0075] On the other hand, the present invention also provides a method for manufacturing the aforementioned front bulkhead assembly, comprising the following steps:

[0076] S1. Manufacture the front upper panel 1;

[0077] The manufacturing steps of the front upper panel 1 include:

[0078] OP10, process the front upper panel process part, the area on the front upper panel process part corresponding to the wheel arch avoidance part 12 is in an unfolded state, the area on the front upper panel process part corresponding to the upper panel body 11 is processed with a first rib groove structure, and the area on the front upper panel process part corresponding to the wheel arch avoidance part 12 is processed with a second rib groove structure.

[0079] OP30, perform fine machining on the front upper panel process parts, shape the second rib groove structure into place, and fold and arch the wheel cover clearance part 12 on the front upper panel 1 into place;

[0080] S2, Manufacturing the lower front panel 2;

[0081] S4. Connect the upper front panel 1 and the lower front panel 2.

[0082] The manufacturing method provided by the present invention avoids directly stamping the wheel cover clearance part 12 on the steel plate in one sequence. Instead, the upper front panel 1 and the lower front panel 2 are manufactured in steps S1 and S2 respectively. Then, the upper front panel 1 and the lower front panel 2 are connected in step S4. When the upper front panel 1 is manufactured, the area on the upper front panel process part corresponding to the wheel cover clearance part 12 in step OP10 is in an unfolded state. This is equivalent to first processing the wheel cover clearance part 12 in a flat state, and then folding the wheel cover clearance part 12 in OP30. This can reduce the processing depth of the wheel cover clearance part 12, reduce the waste area, simplify the mold and improve the material utilization rate, reduce the number of processes and reduce costs.

[0083] Preferably, steps OP10, OP30, and S2 are processed using stamping dies, thus manufacturing the upper front panel and lower front panel separately, and then connecting the upper front panel and lower front panel, which simplifies the stamping die and prevents stamping cracks.

[0084] In one embodiment, step OP10 includes: stamping a steel plate using a first stamping die to draw a first rib groove structure and a second rib groove structure onto the steel plate, obtaining the front upper panel process part, and the first rib groove structure is in a formed state. That is, through the sequential processing of OP10, the first rib groove structure meets the rib groove structure surface requirements on the upper plate body of the finished front upper panel. The process is simple. First, the first rib groove structure on the upper plate body 11 of the front upper panel 1 and the second rib groove structure on the wheel arch clearance part 12 are drawn, while the wheel arch clearance part 12 is in a flattened state, which greatly reduces the drawing depth of OP10. That is, the first stamping die in OP10 achieves shallow drawing of the steel plate, improving the stamping forming performance of the front upper panel 1, preventing stamping cracks, and reducing the scrap area. Compared with the traditional deep drawing process, it greatly improves the material utilization rate. The subsequent positive punching and repair process does not require a wedge die, simplifying the structure of the first stamping die.

[0085] Specifically, such as Figure 9 As shown, the first stamping die includes a first upper die 5, a blank holder 6, and a first lower die 7. The first upper die 5 first moves down to its edge and closes with the blank holder 6, pressing the steel plate tightly. Then, the blank holder 6 moves down synchronously with the first upper die 5, and the steel plate contacts the first lower die 7. The blank holder 6 and the first upper die 5 continue to move down to the bottom of the stamping die, and the steel plate undergoes plastic deformation, drawing out the first rib groove structure and the second rib groove structure to obtain the front upper plate process part.

[0086] In addition, the manufacturing process of the front upper panel 1 also includes the following steps performed between step OP10 and step OP30:

[0087] OP20: Punch and trim the front upper panel process parts to achieve the processing of necessary holes and removal of edge waste on the front upper panel 1.

[0088] In one embodiment, step OP30, the flanging and shaping step, which involves finishing the front upper panel process component, includes: stamping the front upper panel process component using a second stamping die to shape the second rib groove structure into place; folding and arching the portion of the front upper panel process component corresponding to the wheel arch clearance portion 12 into place; thereby shaping the wheel arch clearance portion 12 into place; and flanging the entire circumference of the front upper panel 1 into place. The second stamping die completes the processing of multiple parts of the front upper panel 1, simplifying the process.

[0089] Specifically, such as Figure 10As shown, the second stamping die includes a second upper die and a second lower die 9. The second upper die includes a flanging and shaping cutter block 81 and a blank holder 82. Figure 10 The middle arrow indicates the alignment direction of the flanging and shaping blade 81, the pressure core 82, and the second lower mold 9; the front upper plate process part processed in step OP20 is transferred to the second lower mold 9, then the pressure core 82 moves down and closes with the second lower mold 9 to press the front upper plate process part, and then the flanging and shaping blade 81 moves down to realize the folding, arching and positioning of the part of the front upper plate process part corresponding to the wheel cover avoidance part 12, and the shaping of the second rib groove structure, and to realize the flanging of the front upper plate around the circumference.

[0090] The present invention also provides a method for manufacturing the aforementioned front bulkhead assembly, comprising the following steps:

[0091] S3, Manufacturing front bulkhead reinforcement beam 3;

[0092] Step S4 includes:

[0093] Weld the front bulkhead reinforcing beam 3, the front upper plate 1, and the front lower plate 2.

[0094] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
