Abstract
Description
Technical Field
[0001] This application relates to the field of automotive parts technology, and more particularly to a stamped structural part and a vehicle. Background Technology
[0002] The stamped structural components of a vehicle, such as the body beams, longitudinal beams, and some support components, need to be designed to balance a large stamping depth and sufficient structural strength, depending on the vehicle body performance requirements.
[0003] To ensure sufficient structural strength of stamped components, materials with high yield strength are often selected. However, these materials have low ductility, making one-time stamping difficult. Therefore, it is necessary to disassemble the stamped components, stamp them separately, and then weld them together.
[0004] However, this method of processing stamped structural parts makes the processing operation of stamped structural parts complicated. Utility Model Content
[0005] This application provides a stamped structural part and a vehicle to solve the problem that stamped structural parts need to be disassembled and are inconvenient to process.
[0006] In a first aspect, embodiments of this application provide a stamped structural component, including an integrally stamped stamped body and a connector disposed on the stamped body. The connector is used to connect with a connecting component of a vehicle. The stamped body includes an integrally stamped main board, a side plate, a connecting portion, and a buffer portion. The main board is bent relative to the connector, and the side plate is bent toward one side of the main board.
[0007] The connecting portion is obliquely disposed between the motherboard and the side panel to connect at least a portion of the motherboard and at least a portion of the side panel. The buffer portion is disposed on the side panel and has at least two buffer surfaces that extend sequentially in a direction away from the motherboard.
[0008] In one possible implementation, the stamped structural component provided in this application includes a buffer section comprising a first stage and a second stage, wherein the first stage and the second stage protrude sequentially from the side plate in a direction away from the main plate to form two buffer surfaces.
[0009] In one possible implementation, the stamping structure provided in this application embodiment has the second stage located on the side of the side plate away from the main plate and is inclined relative to the side plate.
[0010] In one possible implementation, the stamping structural member provided in this application embodiment further includes a third stage, which is located between the first stage and the second stage;
[0011] The first stage, the third stage, and the second stage sequentially form three buffer surfaces along the extension direction of the side plate.
[0012] In one possible implementation, the stamped structural member provided in this application embodiment includes at least one of the first stage and the third stage, which comprises a first sub-segment and a second sub-segment connected to each other. The extension direction of the first sub-segment forms an angle with the extension direction of the side plate, and the extension direction of the second sub-segment is consistent with the extension direction of the side plate. The first sub-segment and the second sub-segment form a stepped surface.
[0013] In one possible implementation, the stamped structural component provided in this application has a second sub-segment of the first stage transitionally connected to the first sub-segment of the third stage, and a second sub-segment of the third stage transitionally connected to the second stage.
[0014] In one possible implementation, the stamped structural component provided in this application includes a planar segment in the connecting portion, with the main board and the side plate located on opposite sides of the planar segment, and the planar segment being inclined relative to both the main board and the side plate.
[0015] In one possible implementation, the stamped structural component provided in this application includes two arc-shaped segments in the connecting portion. The two arc-shaped segments are respectively disposed on opposite sides of the planar segment, and the planar segment is respectively transitionally connected to the corresponding main board or the side plate through the two arc-shaped segments.
[0016] In one possible implementation, the stamped structural component provided in this application embodiment has at least two side plates, which are arranged opposite to each other and located on the same side of the main board.
[0017] The spacing between the stepped surfaces of at least two of the side plates that are arranged opposite to each other gradually increases in the direction away from the main plate.
[0018] Secondly, embodiments of this application provide a vehicle, including a vehicle body and any of the aforementioned stamped structural components, wherein the stamped structural components are disposed on the vehicle body.
[0019] The stamped structural component and vehicle provided in this application embodiment include an integrally stamped stamping body and a connecting part disposed on the stamping body. The stamping body includes a main plate, a side plate, a connecting part, and a buffer part. The connection position between the main plate and the side plate is the starting point of the stamping process. The connecting part is located between the main plate and the side plate, which transitions and connects the main plate and the side plate, eliminating sharp connection parts between the main plate and the side plate, making the connection between the main plate and the side plate smoother, and making the starting point of the drawing smoother. The side plate is the part that mainly bears the drawing deformation. A buffer part is provided on the side plate, so that the buffer part forms at least two buffer profiles along the direction away from the main plate. That is, the buffer part forms at least two buffer profiles in the drawing direction of the side plate. The buffer profiles are used to buffer the drawing deformation of the side plate, thereby increasing the drawing depth of the side plate. Thus, by setting connecting parts and buffer parts on the stamped structural parts, the drawing of the stamped structural parts can be made smoother, the drawing depth can be increased, and the drawing crack can be prevented. This allows the stamped structural parts to be formed in one stamping without disassembly, making the processing operation of the stamped structural parts simpler and more efficient.

[0037] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the absence of conflict, the following embodiments and features can be combined with each other.
[0039] As described in the background section, stamped structural components of vehicles, such as body beams, longitudinal beams, and some support components, need to be designed to balance a large stamping depth and sufficient structural strength, depending on the vehicle body performance requirements.
[0040] To ensure sufficient structural strength in stamped structural parts, materials with high yield strength are often selected. However, these materials have low ductility, making one-time stamping difficult. Therefore, it is usually necessary to disassemble the stamped structural part, dividing it into at least two parts according to its shape. Each part is stamped separately and then welded to form a complete stamped structural part. While this approach ensures structural strength and reduces the space occupied by the stamped structural part, it increases the number of dies required in the processing, resulting in higher manufacturing costs. Furthermore, the welding of the various parts makes it difficult to guarantee the overall precision of the stamped structural part, leading to poor processing reliability.
[0041] Alternatively, the draft angle of the stamped structural parts can be increased to slow down the drawing process and reduce the stamping difficulty. However, increasing the draft angle of the stamped structural parts will also increase the size and weight of the stamped structural parts, thus increasing the space occupied in the vehicle interior.
[0042] In addition, the material of the stamped structural parts can be directly replaced. For example, the steel commonly used for stamped structural parts is high-strength cold-rolled duplex steel (HC340 / 590DP), which can be replaced with cold-rolled low-carbon steel (DC06 or DC04) with better ductility. Understandably, although such a setting can allow the stamped structural parts to be stamped in one step, it will reduce the structural strength of the stamped structural parts.
[0043] Therefore, the processing of existing stamped structural parts is relatively inconvenient.
[0044] In order to overcome the defects in the prior art, the stamped structural parts and vehicles provided in this application embodiment, by providing connecting parts and buffer parts on the stamped structural parts, can make the drawing of the stamped structural parts smoother, increase the drawing depth, and prevent drawing cracks, so as to complete the stamping of the stamped structural parts in one stamping without disassembling the parts, making the processing operation of the stamped structural parts simpler and more efficient.
[0045] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the present invention.
[0046] Reference Figures 1 to 5 As shown, this application embodiment provides a stamped structural component, including an integrally stamped stamped body and a connector 500 disposed on the stamped body. The connector 500 is used to connect with a vehicle connection component. The stamped body includes a main board 100, a side plate 200, a connecting portion 300 and a buffer portion 400. The main board 100 is bent relative to the connector 500, and the side plate 200 is bent toward the side of the main board 100.
[0047] The connecting part 300 is inclinedly disposed between the main board 100 and the side plate 200 to connect at least part of the main board 100 and at least part of the side plate 200. The buffer part 400 is disposed on the side plate 200 and has at least two buffer surfaces that extend sequentially in a direction away from the main board 100.
[0048] It is understandable that stamping refers to applying external force to metal sheets through a press and a mold. Under the action of the press, the metal sheet is plastically deformed by using the specific shape and size of the mold, thereby forming a part with the required shape and size.
[0049] The stamped structural parts in this application can be crossbeam structural parts of vehicles, longitudinal beam structural parts of vehicles, or other bracket structural parts on vehicles. The common feature of such structural parts is that the structural parts themselves have a large stamping depth and have high strength requirements.
[0050] In this embodiment, the stamping body can be located at the end of the connecting body 500. The stamping body includes a main plate 100, a side plate 200, a connecting portion 300, and a buffer portion 400. The main plate 100 can be regarded as the base of the stamping body, and the side plate 200 is formed by stamping and drawing the portion of the blank other than the base. Therefore, the drawing length of the side plate 200 can be regarded as the stamping depth of the stamping body.
[0051] A connecting portion 300 is provided between the side plate 200 and the main plate 100. The connecting portion 300 is located at the starting point of the stamping and drawing process. This connecting portion 300 allows for a smooth transition between the main plate 100 and the side plate 200, making the starting point of the drawing process smoother. Compared to a direct connection between the side plate 200 and the main plate 100, the connecting portion 300 eliminates the sharp edges that would result from such a direct connection, blunting the edges and preventing thinning of the stamped component during the stamping process, thus reducing the possibility of breakage. Furthermore, compared to directly eliminating the sharp edges between the main plate 100 and the side plate 200 by adding chamfers or rounded corners, the connecting portion 300 has a larger area, resulting in a smoother starting point for the drawing process, better buffering effect, and easier demolding.
[0052] As the main part bearing the drawing load, it is crucial to ensure the structural integrity of the side plate 200 during the stamping and drawing process. Therefore, a buffer section 400 is provided on the side plate 200. The buffer section 400 can form at least two buffer surfaces in the drawing direction of the side plate 200. Specifically, the buffer surfaces can be stepped surface structures. Due to the presence of the buffer surfaces, during the stamping and drawing process of the stamped structural part, the side plate 200 can be transitioned and buffered at the buffer surfaces when deformed, avoiding stress concentration caused by continuous deformation of the side plate 200. This makes the stress on the side plate 200 more uniform during deformation, preventing the side plate 200 from cracking and being damaged, thereby enabling the stamped structural part to have a larger drawing depth.
[0053] Therefore, in the stamping structural component provided in this application embodiment, the connecting portion 300 is located between the main plate 100 and the side plate 200, providing a smoother connection between the main plate 100 and the side plate 200, resulting in a smoother starting point for the drawn part. Furthermore, a buffer portion 400 is provided on the side plate 200, forming at least two buffer surfaces along the drawing direction of the side plate 200 to buffer the drawing deformation of the side plate 200, thereby increasing the drawing depth of the side plate 200. This allows for smoother drawing of the stamping structural component and the stamping body, increases the drawing depth, and prevents drawing cracks. It enables the stamping of the structural component to be completed in one stamping operation at the stamping body without disassembly, making the processing of the stamping structural component simpler and more efficient.
[0054] Furthermore, this design eliminates the need to increase the draft angle at the stamping body of the stamped structural component, preventing an increase in the component's size and excessive occupation of vehicle space, thus ensuring a compact structure. Simultaneously, it eliminates the need to change the processing material of the stamped structural component, allowing it to balance structural strength and drawing depth.
[0055] Furthermore, it should be noted that in order to improve the stamping efficiency of the stamped structural parts in this application embodiment, a stamping die adapted to the stamping structural parts can be provided. Compared with traditional dies, the stamping die has a structure corresponding to the connecting part 300 and the buffer part 400, eliminating the need to add multiple sets of dies corresponding to the disassembly structure, thus preventing a significant increase in the processing cost of the stamped structural parts.
[0056] Reference Figures 1 to 5 As shown, the buffer section 400 includes a first stage 410 and a second stage 420. The first stage 410 and the second stage 420 protrude sequentially from the side plate 200 away from the main plate 100 along the side plate 200 to form two buffer surfaces.
[0057] It is understandable that by setting the first stage 410 and the second stage 420 to protrude sequentially along the drawing direction of the side plate 200 and form two buffer surfaces, different degrees of buffering effect can be provided in stages during the drawing process of the side plate 200, so that the buffer part 400 can more effectively disperse stress and avoid stress concentration.
[0058] The second stage 420 is located on the side of the side panel 200 away from the main board 100 and is tilted relative to the side panel 200.
[0059] The second stage 420 is positioned on the side of the side plate 200 away from the main plate 100, specifically at the edge of the side plate 200 away from the main plate 100. The second stage 420 is tilted relative to the side plate 200, thus positioning the second stage 420 at the end point of the drawing of the side plate 200. This allows the second stage 420 to smoothly release the drawing force at the end point of the drawing of the side plate 200, eliminating stress concentration during the drawing process of the side plate 200. This ensures that the stamping body of the stamped structural part can be successfully stamped and drawn without cracking.
[0060] Furthermore, tilting the second stage 420 allows the second stage 420 to transitionally connect the side plate 200 and the flange structure located on the side of the side plate 200 away from the main board 100, making the overall structure of the stamped component smoother, avoiding the formation of sharp corners, and further ensuring that the stamped component can be stamped smoothly.
[0061] Furthermore, in some embodiments, reference is made to... Figures 1 to 5 As shown, the buffer section 400 also includes a third stage 430, which is located between the first stage 410 and the second stage 420.
[0062] The first stage 410, the third stage 430, and the second stage 420 form three buffer surfaces in sequence along the extension direction of the side plate 200.
[0063] By setting a third stage 430 between the first stage 410 and the second stage 420, the third stage 430 forms a transition between the first stage 410 and the second stage 420, so that the third stage 430 forms an additional buffer surface between the buffer surface formed by the first stage 410 and the buffer surface formed by the second stage 420. The three buffer surfaces can further improve the buffering effect of the buffer section 400 on the side plate 200 during the drawing process, and effectively increase the drawing depth of the side plate 200.
[0064] In specific implementation, refer to Figure 1 and Figure 5 As shown, at least one of the first stage 410 and the third stage 430 includes a first sub-segment and a second sub-segment connected to each other. The extension direction of the first sub-segment is at an angle to the extension direction of the side plate 200, and the extension direction of the second sub-segment is consistent with the extension direction of the side plate 200. The first sub-segment and the second sub-segment form a stepped surface.
[0065] It is understandable that the first sub-segment a 411 of the first stage 410 and the first sub-segment b 431 of the third stage 430 both form an angle with the extension direction of the side plate 200, and the second sub-segment a 412 of the first stage 410 and the second sub-segment b 432 of the third stage 430 are both set along the extension direction of the side plate 200. That is, the first sub-segment and the second sub-segment extend in different directions, which can disperse the drawing pressure and stress to different extension paths, avoid stress concentration, and improve the support capacity and stability of the side plate 200.
[0066] Furthermore, in this embodiment, the first stage 410 on one side panel 200 of the motherboard 100 has a first sub-segment a 411 and a second sub-segment a 412, and the third stage 430 also has a first sub-segment b 431 and a second sub-segment b 432. On the other side panel 200 of the motherboard 100, the first stage 410 only has the second sub-segment a 412, and the third stage 430 has a first sub-segment b 431 and a second sub-segment b 432.
[0067] In other embodiments, the first stage 410 and the third stage 430 on the side plates 200 on both sides of the motherboard 100 may each have a first sub-segment and a second sub-segment, and the second stage 420 may also have a first sub-segment and a second sub-segment. This application does not limit this.
[0068] Furthermore, referring to Figure 5 As shown, the second sub-segment a 412 of the first stage 410 is transitionally connected to the first sub-segment b 431 of the third stage 430, and the second sub-segment b 432 of the third stage 430 is transitionally connected to the second stage 420.
[0069] This arrangement, where the first stage 410, the third stage 430, and the second stage 420 are continuously arranged on the side plate 200, makes the stamping main structure of the stamping component more compact. Furthermore, during the drawing process, the side plate 200 is continuously and uninterruptedly buffered by the buffer section 400, thereby increasing the drawing limit and drawing depth of the side plate 200 and preventing the side plate 200 from cracking during the drawing process.
[0070] Furthermore, in some embodiments, reference is made to Figures 1 to 5 As shown, the connecting part 300 includes a planar section 310, with the main board 100 and the side plate 200 located on opposite sides of the planar section 310. The planar section 310 is inclined relative to both the main board 100 and the side plate 200.
[0071] It is understandable that by setting the planar segment 310 to connect the main board 100 and the side plate 200, and by tilting the planar segment 310 towards the main board 100 and the side plate 200, the planar segment 310 can be used to transition between the main board 100 and the side plate 200, eliminating the sharp edges caused by the direct connection between the main board 100 and the side plate 200, blunting the connection part between the main board 100 and the side plate 200, reducing the sharpness of the drawing start point, and effectively maintaining the smoothness of the drawing start point.
[0072] Furthermore, refer to Figures 1 to 5 As shown, the connecting part 300 also includes two arc-shaped segments 320, which are respectively disposed on opposite sides of the flat segment 310. The flat segment 310 is connected to the corresponding main board 100 or side plate 200 through the two arc-shaped segments 320.
[0073] It is understandable that by setting the curved section 320, the edge structure generated when the flat section 310 is connected to the motherboard 100 or the side plate 200 can be further eliminated, making the connection between the flat section 310 and the motherboard 100 or the side plate 200 smoother.
[0074] In specific settings, the two sides of the curved section 320 are tangent to the flat section 310 and the corresponding main board 100 or side plate 200, respectively, to ensure the transition connection effect of the curved section 320.
[0075] Furthermore, when the stamped structural parts are specifically crossbeam or longitudinal beam components, it is necessary to ensure their stable support effect on the vehicle body, so refer to... Figures 1 to 5 As shown, at least two side panels 200 are required, the at least two side panels 200 are arranged opposite each other, and the at least two side panels 200 are located on the same side of the main board 100.
[0076] The spacing between the corresponding stepped surfaces of at least two side plates 200 that are set opposite to each other gradually increases in the direction away from the main plate 100.
[0077] Among them, the spacing between the corresponding step surfaces on the two side plates 200 gradually increases in the direction away from the main plate 100, which makes the spacing between the two side plates 200 increase with the step surfaces, so that the stamped structural parts can be smoothly separated from the mold during the mold release process.
[0078] Furthermore, both side panels 200 are connected to the main board 100 via connecting parts 300, and both side panels 200 are provided with buffer parts 400.
[0079] This application also provides a vehicle, including a vehicle body and a stamped structural member as described in any of the above embodiments, the stamped structural member being disposed on the vehicle body.
[0080] The stamped structural components have been described in detail in the above embodiments and will not be repeated here.
[0081] The vehicle provided in this application embodiment includes a stamped structural component. This component comprises a connector 500 and a stamped body disposed on the connector 500. The stamped body includes an integrally stamped main plate 100, side plates 200, a connecting portion 300, and a buffer portion 400. The connection point between the main plate 100 and the side plates 200 is the starting point of the stamping process. The connecting portion 300 is located between the main plate 100 and the side plates 200, providing a transitional connection between them, thus eliminating the need for friction between the main plate 100 and the side plates 200. The sharp connection between the main board 100 and the side plate 200 makes the connection smoother and the starting point of the drawing more even. The side plate 200 is the main part that bears the drawing deformation. A buffer part 400 is provided on the side plate 200, so that the buffer part 400 forms at least two buffer surfaces along the extension direction of the side plate 200. That is, the buffer part 400 forms at least two buffer surfaces in the drawing direction of the side plate 200. The buffer surfaces are used to buffer the drawing deformation of the side plate 200, so as to increase the drawing depth of the side plate 200.
[0082] Thus, by providing a connecting part 300 and a buffer part 400 on the stamped structural part, the drawing of the stamped structural part can be made smoother, the drawing depth can be increased, and the drawing crack can be prevented. This allows the stamped structural part to be formed in one stamping without disassembly, making the processing operation of the stamped structural part simpler and more efficient.
[0083] Furthermore, this design eliminates the need to increase the draft angle of the stamped structural parts, thus avoiding an increase in the size of the stamped structural parts and excessive occupation of vehicle space, ensuring the compact structure of the stamped structural parts. At the same time, it also eliminates the need to change the processing material of the stamped structural parts, allowing the stamped structural parts to balance structural strength and drawing depth.
