[0002] The body of a vehicle includes a variety of structural parts, some of which are formed by stamping of sheet metal. Part of the sheet metal area eventually forms the structural part, and the other area of ​​the sheet metal is used to assist in the processing of the structural part. In the related art, the other area of ​​the sheet metal used to assist in the processing of the structure accounts for a large proportion, resulting in sheet metal waste. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a sheet material, a structural part, a method for manufacturing the same, and a vehicle to solve the technical problem of sheet material waste.

[0004] To achieve the above purpose, the technical solution adopted in this application is:

[0005] In a first aspect, a sheet material is provided, which is used for processing a structural part of a vehicle body, and the sheet material includes a first part and a second part, wherein the first part is used for forming the structural part, at least a portion of the second part surrounds the first part, and the at least a portion of the second part is connected to the first part, and the second part is used for assisting in processing the structural part, and the outer peripheral edge of the second part includes a plurality of edges. The difference between the minimum distance between any two edges of the outer peripheral edge of the second part and the edge of the first part is a, and the value range of a is: 0mm≤a≤30mm.

[0006] Through the above technical solution, the sheet material provided by the present application controls the difference in the minimum distance between the outer peripheral edge of the second part and the edge of the first part to within 30 mm, which can reduce the area of ​​the second part, and the second part is used for auxiliary processing of structural parts, not for forming structural parts, thereby reducing the waste of sheet material.

[0007] Therefore, the sheet material provided by the present application can solve the technical problem of sheet material waste.

[0008] In some embodiments, the value range of a is: 0mm≤a≤5mm, or 5mm≤a≤10mm, or 10mm≤a≤15mm, or 15mm≤a≤20mm, or 20mm≤a≤25mm, or 25mm≤a≤30mm.

[0009] In some embodiments, the minimum distance between the edge of the first portion and any side of the outer peripheral edge of the second portion is b, and the value range of b is: 150 mm≤b≤180 mm.

[0010] In this way, the minimum distance between the edge of the first part and the outer peripheral edge of the second part can be controlled between 150 mm and 180 mm, so that the sheet material can be processed into a structural part and material waste can be reduced. Among them, the minimum distance between the edge of the first part and the outer peripheral edge of the second part is greater than or equal to 150 mm, so that the second part can play a role in assisting the processing of the structural part. In addition, the minimum distance between the edge of the first part and the outer peripheral edge of the second part is less than 180 mm, which can reduce the area of ​​the second part and further reduce the waste of sheet material.

[0011] In some embodiments, the value range of b is: 150mm≤b≤155mm, or 155mm≤b≤160mm, or 160mm≤b≤165mm, or 165mm≤b≤170mm, or 170mm≤b≤175mm, or 175mm≤b≤180mm.

[0012] In some embodiments, the multiple sides of the outer peripheral edge of the second part include a first side, a second side, a third side and a fourth side, and the first side, the second side, the third side and the fourth side are connected in sequence to form a quadrilateral, and the minimum angle of the quadrilateral is α, and the value range of α is: 55°≤α<60°.

[0013] In this way, when the sheet material provided by the present application is cut by the swing shear, the swing shear angle is greater than 30° and less than or equal to 35°. Compared with the swing shear angle of 30°, the closest distance between the edge of the second part and the edge of the first part can be reduced, which is conducive to reducing the area of ​​the second part, thereby helping to reduce the waste of sheet material.

[0014] In some embodiments, the value range of α is: 55°≤α≤56°, or, 56°≤α≤57°, or, 57°≤α≤8°, or, 58°≤α≤59°, or, 59°≤α<60°.

[0019] The third process is performed on the sheet material at the third workstation, and the sheet material is rotated in a second direction by a second preset angle, the second direction is opposite to the first direction, and the second preset angle is equal to the first preset angle.

[0020] Through the above technical solution, the manufacturing method provided by the present application can rotate the sheet material in the first direction by a first preset angle at the first station, and the sheet material is rotated from the first posture to the second posture, so as to facilitate the second process of the sheet material at the second station.

[0022] In some embodiments, the multiple sides of the outer peripheral edge of the sheet include a first side, a second side, a third side and a fourth side, and the first side, the second side, the third side and the fourth side are sequentially connected to form a quadrilateral, and the minimum angle of the quadrilateral is α, and the value of α is: 55°≤α<60°.

[0023] In this way, when the sheet material provided by the present application is cut by the swing shear, the swing shear angle is greater than 30° and less than or equal to 35°. Compared with the swing shear angle of 30°, the closest distance between the edge of the second part and the edge of the first part can be reduced, which is conducive to reducing the area of ​​the second part, thereby helping to reduce the waste of sheet material.

[0024] In addition, the swing shear angle of the sheet metal during cutting will not impose any restrictions on the manufacturing method of the structural component.

[0025] In some embodiments, the first preset angle is β, and β satisfies the formula: 60°≤α+β≤120°, or the value range of β is: 0°<β≤65°.

[0028] In this way, the manufacturing method provided in the present application controls the difference in the minimum distance between the outer peripheral edge of the second part of the sheet and the edge of the first part to within 30 mm, which can reduce the area of ​​the second part, and the second part is used to assist in processing structural parts, not for forming structural parts, thereby reducing the waste of sheet material.

[0029] In addition, the manufacturing method provided in the present application can control the minimum distance between the edge of the first part of the sheet and the outer peripheral edge of the second part to be between 150 mm and 180 mm, so that the sheet can be processed into a structural part and material waste can be reduced.

[0052] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0053] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0054] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0055] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0056] See also Figure 1 The embodiment of the present application provides a vehicle 100, which can be a pure electric vehicle, or other battery-powered vehicle 100, such as a hybrid vehicle. Of course, the vehicle 100 can also be a fuel vehicle 100 or other power vehicle 100, such as a hydrogen energy vehicle 100.

[0057] The vehicle 100 includes a vehicle body 110, and the vehicle body 110 of the vehicle 100 generally includes a variety of structural parts 20, some of which are formed by stamping a sheet material 10. Partial areas of the sheet material 10 eventually form the structural parts 20, and other areas of the sheet material 10 are used to assist in processing the structural parts 20. For example, other areas of the sheet material 10 are used as clamping areas or process supplementary areas.

[0058] Optionally, the sheet material 10 includes a first portion 11 and a second portion 12, the first portion 11 is used to form the structural member 20, at least a portion of the second portion 12 surrounds the first portion 11, and the at least a portion of the second portion 12 is connected to the first portion 11, and the second portion 12 is used to assist in processing the structural member 20. That is, a partial area of ​​the sheet material 10 is located in the first portion 11, and the other area of ​​the sheet material 10 is located in the second portion 12.

[0059] See also Figure 2 The inventors found that the sheet material 10 is usually cut by swing shearing, and the swing shearing angle θ is limited by the processing technology of the sheet material 10 and is usually below a preset angle, that is, the swing shearing angle θ is less than or equal to the preset angle.

[0060] See also Figure 3 For example, in the related art, the swing shear angle θ1 of the sheet material 10 is 30°. This results in a large area of ​​the second portion 12 used for the auxiliary processing structure, resulting in waste of the sheet material 10.

[0061] In addition, the second part 12 surrounds the first part 11 , and along the direction of surrounding the first part 11 , the outer peripheral edge of the second part 12 is not uniformly spaced from the outer peripheral edge of the first part 11 , and a portion of the second part 12 has a large wasted area.

[0062] Please also read Figure 3 and Figure 4 In order to solve the above technical problems, the present application provides a sheet material 10, which is used to process a structural member 20 of a vehicle body 110, wherein the outer peripheral edge of the second portion 12 includes a plurality of edges. The difference between the minimum distance between any two edges of the outer peripheral edge of the second portion 12 and the edge of the first portion 11 is a, and the value range of a is: 0mm≤a≤30mm.

[0063] In this way, the sheet material 10 provided in the embodiment of the present application controls the difference in the minimum distance between the outer peripheral edge of the second part 12 and the edge of the first part 11 to within 30 mm, which can reduce the area of ​​the second part 12, and the second part 12 is used to assist in the processing of the structural part 20, not for forming the structural part 20, thereby reducing the waste of the sheet material 10.

[0064] Therefore, the sheet material 10 provided in the embodiment of the present application can solve the technical problem of sheet material 10 waste.

[0065] Optionally, the value range of a may be: 0mm≤a≤10mm. Optionally, the value range of a may be: 0mm≤a≤5mm. Optionally, the value range of a may be: 5mm≤a≤10mm.

[0066] Optionally, the value range of a may be: 10mm≤a≤20mm. Optionally, the value range of a may be: 10mm≤a≤15mm. Optionally, the value range of a may be: 15mm≤a≤20mm.

[0067] Optionally, the value range of a may be: 20mm≤a≤30mm. Optionally, the value range of a may be: 20mm≤a≤25mm. Optionally, the value range of a may be: 25mm≤a≤30mm.

[0068] Optionally, the value of a can be one of: 0mm, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, and 30mm.

[0069] Optionally, the value of a can also be: 0.5mm, 1.5mm, 2.5mm, 3.5mm, 4.5mm, 5.5mm, 6.5mm, 7.5mm, 8.5mm, 9.5mm, 10.5mm, 11.5mm, 12.5mm, 13.5mm, 14.5mm, 15.5mm, 16.5mm, 17.5mm, 18.5mm, 19.5mm, 20.5mm, 21.5mm, 22.5mm, 23.5mm, 24.5mm, 25.5mm, 26.5mm, 27.5mm, 28.5mm, 29.5mm.

[0070] It is understandable that the difference a between the minimum distances between any two sides of the outer peripheral edge of the second portion 12 and the edge of the first portion 11 can be specifically selected according to the model and size of the structural member 20 and the sheet material 10 .

[0071] In some embodiments, the minimum distance between the edge of the first portion 11 and any side of the outer peripheral edge of the second portion 12 is b, and the value range of b is: 150 mm≤b≤180 mm.

[0072] In this way, the sheet material 10 provided in the embodiment of the present application can control the minimum distance between the edge of the first part 11 and the outer peripheral edge of the second part 12 to be between 150 mm and 180 mm, so that the sheet material 10 can be processed into the structural part 20 and material waste can be reduced.

[0073] The minimum distance between the edge of the first part 11 and the outer peripheral edge of the second part 12 is greater than or equal to 150 mm, so that the second part 12 can play a role in assisting the processing of the structural member 20. In addition, the minimum distance between the edge of the first part 11 and the outer peripheral edge of the second part 12 is less than 180 mm, which can reduce the area of ​​the second part 12 and further reduce the waste of the sheet material 10.

[0074] Optionally, the value range of b may be: 150 mm ≤ b ≤ 160 mm. Optionally, the value range of b may be: 150 mm ≤ b ≤ 155 mm. Optionally, the value range of b may be: 155 mm ≤ b ≤ 160 mm.

[0075] Optionally, the value range of b may be: 160 mm ≤ b ≤ 170 mm. Optionally, the value range of b may be: 160 mm ≤ b ≤ 165 mm. Optionally, the value range of b may be: 165 mm ≤ b ≤ 170 mm.

[0076] Optionally, the value range of b may be: 170 mm ≤ b ≤ 180 mm. Optionally, the value range of b may be: 170 mm ≤ b ≤ 175 mm. Optionally, the value range of b may be: 175 mm ≤ b ≤ 180 mm.

[0077] Optionally, the value of b can be: 150mm, 151mm, 152mm, 153mm, 154mm, 155mm, 156mm, 157mm, 158mm, 159mm, 160mm, 161mm, 162mm, 163mm, 164mm, 165mm, 166mm, 167mm, 168mm, 169mm, 170mm, 171mm, 172mm, 173mm, 174mm, 175mm, 176mm, 177mm, 178mm, 179mm, 180mm.

[0078] Optionally, the value of b can also be: 150.5mm, 151.5mm, 152.5mm, 153.5mm, 154.5mm, 155.5mm, 156.5mm, 157.5mm, 158.5mm, 159.5mm, 160.5mm, 161.5mm, 162.5mm, 163.5mm, 164.5mm, 165.5mm, 166.5mm, 167.5mm, 168.5mm, 169.5mm, 170.5mm, 171.5mm, 172.5mm, 173.5mm, 174.5mm, 175.5mm, 176.5mm, 177.5mm, 178.5mm, 179.5mm.

[0079] It is understandable that the minimum distance b between the edge of the first portion 11 and any one side of the outer peripheral edge of the second portion 12 can be specifically selected according to the model and size of the structural member 20 and the sheet material 10 .

[0080] Optionally, the sheet material 10 provided in the present application can reduce the value of a and / or b by adjusting the swing shear angle. For example, the swing shear angle θ2 of the sheet material 10 provided in the present application is 35°.

[0081] Please continue reading Figure 3 and Figure 4 In some embodiments, the multiple edges of the outer peripheral edge of the second part 12 include a first edge 101, a second edge 102, a third edge 103 and a fourth edge 104. The first edge 101, the second edge 102, the third edge 103 and the fourth edge 104 are connected in sequence to form a quadrilateral. The minimum angle of the quadrilateral is α, and the value of α is: 55°≤α<60°.

[0082] For example, the angle formed by the first side 101 and the second side 102 is α. It can be understood that the angle α formed by the first side 101 and the second side 102 and the swing shear angle θ2 of the sheet material 10 provided in the present application are complementary angles, that is, α+θ2=90°.

[0083] It is understandable that when the sheet material 10 provided in the present application is cut by the swing shear, the swing shear angle θ2 is greater than 30° and less than or equal to 35°, that is, 30°<θ2≤35°. Compared with the related art, the swing shear angle θ1 is 30°, which can reduce the minimum distance between the edge of the second part 12 and the edge of the first part 11, which is beneficial to reducing the area of ​​the second part 12, thereby helping to reduce the waste of the sheet material 10.

[0084] Optionally, the value range of α may be: 55°≤α≤57°. Optionally, the value range of α may be: 55°≤α≤56°. Optionally, the value range of α may be: 56°≤α≤57°.

[0085] Optionally, the value range of α may be: 57°≤α<60°. Optionally, the value range of α may be: 57°≤α≤58°. Optionally, the value range of α may be: 58°≤α≤59°. Optionally, the value range of α may be: 59°≤α<60°.

[0086] Optionally, the value of α may be one of 55°, 56°, 57°, 58°, and 59°.

[0087] Optionally, the value of α may also be one of 55.5°, 56.5°, 57.5°, 58.5°, and 59.5°.

[0088] It is understandable that the value of the minimum angle α of the quadrilateral formed by the outer peripheral edges of the second portion 12 can be specifically selected according to the model and size of the structural member 20 and the sheet material 10 .

[0089] The present application also provides a structural member 20, which is used in the vehicle body 110 and can be made from the sheet material 10 of any of the above embodiments. The structural member 20 provided in the present application has the same or similar technical effects as the sheet material 10 of any of the above embodiments, which will not be described in detail here.

[0090] Optionally, the structural member 20 includes a fender. That is, the fender on the vehicle body 110 can be manufactured from the sheet material 10 of the above embodiment. It is understandable that other structural members 20 on the vehicle body 110 can also be manufactured from the sheet material 10 of the above embodiment, such as the enclosure.

[0091] Please also read Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 In order to manufacture a structural member 20 using the sheet material 10, the embodiment of the present application further provides a method for manufacturing the structural member 20, wherein the structural member 20 is used for a vehicle body 110, and the manufacturing method comprises:

[0092] S1, providing a sheet material 10. Optionally, please refer to Figure 4 and Figure 5 After the sheet 10 is cut by the swing, it reaches the blanking station for preparing the structural part 20 for subsequent processing. It can be understood that the sheet 10 of the manufacturing method provided in the embodiment of the present application can be the sheet 10 of any of the above embodiments, and has the same technical effect as the sheet 10 of the above embodiments.

[0093] For example, the multiple sides of the outer peripheral edge of the second part 12 include a first side 101, a second side 102, a third side 103 and a fourth side 104. The first side 101, the second side 102, the third side 103 and the fourth side 104 are connected in sequence to form a quadrilateral, and the minimum angle of the quadrilateral is α, and the value of α is: 55°≤α<60°.

[0094] For example, the sheet material 10 includes a first part 11 and a second part 12, the first part 11 is used to form a structural part 20, at least part of the second part 12 is arranged to surround the first part 11, and the at least part of the second part 12 is connected to the first part 11, and the second part 12 is used to assist in the processing of the structural part 20. The outer peripheral edge of the second part 12 includes a plurality of edges. Among them, the difference between the minimum distance between any two edges of the outer peripheral edge of the second part 12 and the edge of the first part 11 is a, and the value range of a is: 0mm≤a≤30mm. In this way, the preparation method provided in the embodiment of the present application can solve the technical problem of waste of sheet material 10.

[0095] For example, the minimum distance between the edge of the first part 11 and any side of the outer peripheral edge of the second part 12 is b, and the value range of b is: 150mm≤b≤180mm. In this way, the preparation method provided in the embodiment of the present application can control the minimum distance between the edge of the first part 11 and the outer peripheral edge of the second part 12 to be between 150mm and 180mm, so that the sheet material 10 can be processed into the structural part 20, and material waste can be reduced.

Figure 6 Optionally, the first station is a palletizing station, and the first process is a palletizing process. The manufacturing method provided in the present application can rotate the sheet material 10 at a first preset angle β from a first posture to a second posture at the palletizing station.

The manufacturing method provided in the present application can destacking the sheet material 10 in the destacking process.

[0098] It is understood that the destacking is performed by blowing the sheet 10 in a direction parallel to the sheet 10 using airflow, and then transporting the sheet 10 to the next station. Figure 6 The destacking angle λ cannot be greater than 30°. If the destacking angle λ is greater than 30°, the destacking effect will be affected. The destacking angle λ is the angle between the side of the sheet 10 opposite to the airflow direction (e.g., the first side 101) and the Y direction. The Y direction is perpendicular to the X direction and parallel to the sheet 10.

[0099] Therefore, the manufacturing method provided in the embodiment of the present application can rotate the sheet material 10 in the first direction by a first preset angle at the first workstation (stacking workstation), and the sheet material 10 is rotated from the first posture to the second posture, thereby reducing the destacking angle, making it easier to perform the second process (destacking process) on the sheet material 10 at the second workstation (destacking workstation).

[0100] See also Figure 8 , S4, performing a third process on the sheet material 10 at the third station, and moving the sheet material 10 along the second direction (such as Figure 8 The sheet 10 is rotated by a second preset angle (in the Z2 direction in the center), the second direction is opposite to the first direction, and the second preset angle is equal to the first preset angle. Optionally, the third station is a centering station, and the third process is a centering process. In this way, the manufacturing method provided by the present application can rotate the sheet 10 from the second posture to the first posture at the centering station, so that the sheet 10 can be subsequently processed.

[0101] See also Fig. 9 S5, stamping the sheet material 10 to form a structural member 20. Optionally, the structural member 20 includes a fender. That is, the fender on the vehicle body 110 can be manufactured from the sheet material 10 of the above embodiment. It is understandable that other structural members 20 on the vehicle body 110 can also be manufactured from the sheet material 10 of the above embodiment, such as a panel.

[0102] Please also read Figure 6 and Fig.11 In some embodiments, the first preset angle β satisfies the formula: 60°≤α+β≤120°, or the value range of β is: 0°<β≤65°.

[0103] In this way, the manufacturing method provided in the present application can rotate the sheet material 10 in the first direction by a first preset angle at the first station, and the sheet material 10 is rotated from the first posture to the second posture, so as to facilitate the second process of the sheet material 10 at the second station.

[0105] Optionally, the value of β can be: 1°, 2°, 3°, 4°, 5°, 7°, 10°, 13°, 15°, 17°, 20°, 23°, 25°, 27°, 30°, 33°, 35°, 37°, 40°, 43°, 45°, 47°, 50°, 53°, 55°, 57°, 60°, 63°, 65°, etc.

[0106] It is understandable that, at the first station (palletizing station), when the angle (palletizing angle λ) between the first edge 101 and the airflow direction Y is less than or equal to 30°, the second posture of the sheet material 10 can have a variety of postures.
