[0088] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0089] In the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art will appreciate that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit the difference. It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way. In the embodiments of the present application, "at least one" refers to one or more, and "more" refers to two or more.

[0090] It should be noted that the "at..." in the embodiment of the present application can be the instant when a certain situation occurs, or can be a period of time after a certain situation occurs, and the embodiment of the present application does not specifically limit this. In addition, the design method of a bumper shaping surface provided in the embodiment of the present application is only used as an example, and a design method of a bumper shaping surface can also include more or less content.

[0091] In modern car design, the bumper is not only an important part of the vehicle's appearance, but also has the function of absorbing impact energy and protecting passengers and the vehicle body. In traditional design, the design of the bumper depends on the designer's experience. The designer uses intuitive judgment to determine the location of electrical components (such as cameras, radars) and the layout of the license plate, and ensures sufficient air intake to meet the engine cooling requirements, while also meeting the collision test standards.

[0092] However, this approach has certain limitations, as the designer’s experience may not be sufficient to take into account all complex factors, such as aerodynamic performance, pedestrian protection requirements, and different regulatory requirements in different regions. Therefore, multiple modifications are usually required after the initial design stage to achieve the final design goal, which prolongs the development cycle of the bumper styling surface and increases the design cost.

[0093] Based on this, the embodiments of the present application propose a design method, device, equipment, medium and product for a bumper styling surface, which can be used in the field of automobile design technology, and aim to solve the above technical problems of the prior art, so as to systematically classify and inspect multiple factors affecting the bumper styling, so that designers can identify potential problems earlier and make optimization adjustments in the early stages of design, thereby improving the quality and efficiency of the design, reducing the number of later changes to the bumper styling surface, shortening the bumper styling surface development cycle, and reducing development costs.

[0094] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0095] Figure 1 A schematic diagram of a design method for a bumper profile provided in an embodiment of the present application Figure 1 .like Figure 1 As shown, the method includes:

[0096] S101, obtaining a vehicle layout drawing, and setting a vehicle coordinate system for the vehicle layout drawing, so as to extract position information of multiple target components affecting the bumper styling surface in the vehicle coordinate system from the vehicle layout drawing through three-dimensional software.

[0097] In an embodiment of the present application, the executor of a method for designing a bumper styling surface may be a server, which may be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server, etc., and no specific restrictions are made here.

[0098] The server can first obtain a vehicle layout drawing of a vehicle whose bumper styling surface is to be designed, and set a vehicle coordinate system for the vehicle layout drawing, so as to extract position information of multiple target components affecting the bumper styling surface in the vehicle coordinate system from the vehicle layout drawing through three-dimensional software, such as Auto Computer-Aided Design (AutoCAD).

[0099] The position information of multiple target components includes: bumper bottom position, bumper longitudinal position, approach angle, front overhang boundary position, pendulum collision area, bumper air intake area, radiator area, multiple functional component areas and license plate area, etc.

[0100] That is to say, the server can determine the approach angle and front overhang boundary based on the vehicle layout diagram, and set the pendulum model to delineate the pendulum collision area on the front bumper area, and can determine the position of the radiator tank on the bumper area based on the vehicle layout diagram, and determine the positions of multiple functional components and the license plate position in the bumper area.

[0101] Among them, the bottom position of the bumper refers to the position of the lowest end of the vehicle's bumper, that is, the distance between the lowest edge of the vehicle's front bumper and the ground.

[0102] The longitudinal position of the bumper refers to the specific installation position of the bumper in the front and rear direction of the vehicle, that is, the installation position of the bumper in the length direction of the vehicle. The design of this position has a direct impact on the vehicle's safety performance, collision test results and appearance design.

[0103] The approach angle (also called the departure angle) refers to the minimum angle at which the front end of a vehicle can approach an obstacle without colliding. Specifically, it is the angle between the point where the front wheels of the vehicle touch the ground and the lowest point of the front end of the vehicle. The approach angle of the bumper is an important parameter in automobile design. It is directly related to the vehicle's passability and driving safety under complex road conditions, and can directly affect the vehicle's ability to pass on rough terrain.

[0104] The front overhang boundary position refers to the horizontal distance from the center of the vehicle's front wheel to the front end of the vehicle (usually the front end of the front bumper), that is, the distance from the center line of the front wheel axle to the front end point of the vehicle, which is the length of the front overhang.

[0105] The pendulum impact area refers to the specific location where the pendulum hits the vehicle in a pendulum impact test. The pendulum impact test is usually performed in the center and on both sides of the bumper to test the performance of the entire bumper. Specifically, the distance between the center point of the pendulum impact area and the ground can be 445 mm, the distance between the upper edge of the pendulum impact area and the ground can be 502 (i.e. 445+57) mm, and the distance between the lower edge of the pendulum impact area and the ground can be 388 (i.e. 445-57) mm.

[0106] The bumper air intake area refers to the opening or grille on the front bumper of the vehicle designed to direct air into the engine compartment to provide sufficient air flow to the engine, radiator and other cooling systems to ensure that the engine operates within the preset temperature range.

[0107] The radiator tank area refers to the area at the front of the vehicle used to install the radiator tank (also called radiator or cooler).

[0108] The multiple functional component areas include a fog lamp area, a radar area, a sensor area, a front camera area and other functional component areas.

[0109] License plate area means the area on the front and rear bumpers of a vehicle that is designed specifically for mounting and displaying the vehicle license plate.

[0110] In modern vehicle design, the front bumper is not just a protective device, but also integrates multiple functional components. The design of these functional areas needs to take into account cooling performance, aerodynamic performance, safety and aesthetics.

[0111] S102: construct a design constraint model diagram of a bumper styling surface according to position information of a plurality of target components, and design the bumper styling surface based on the design constraint model diagram.

[0112] Specifically, the design constraint model diagram is used to indicate the constraint conditions between multiple target component position information through a graphic.

[0113] The server may construct a design constraint model diagram of the bumper styling surface according to the position information of multiple target components, and design the bumper styling surface based on the design constraint model diagram. Figure 2 A schematic diagram of a bumper profile provided in an embodiment of the present application Figure 1 . Figure 2 This is the front view of the bumper styling surface, such as Figure 2 As shown, the bumper styling surface 10 includes a front vehicle logo area 20, a front camera area 30, a radar area 40, a radiator area 50, a front license plate area 60, a front anti-collision beam area 70, a pendulum collision area 80 and a bumper bottom position 90. The bumper bottom position 90 refers to the distance between the bottom edge of the front bumper of the vehicle and the ground 901.

[0114] S103, obtaining a functional component area on the bumper molding surface, a pendulum collision area, a first gap size between the functional component and the structural hard point of the bumper, and a second gap size between the bumper and the anti-collision beam.

[0115] In the embodiments of the present application, the structural hard points of the bumper refer to key positions that must be fixed or supported in the bumper design. These positions are usually the main support points for connecting the bumper to the body or other components, such as structural hard points such as sheet metal or anti-collision beams.

[0116] Specifically, the server can further obtain multiple functional component areas on the bumper molding surface, the pendulum collision area, the first gap size between multiple functional components and the structural hard points of the bumper, and the second gap size between the bumper and the anti-collision beam, so as to further determine whether the design of the multiple functional component areas on the bumper molding surface is reasonable.

[0117] S104: If the functional component area is outside the pendulum collision area, and the first gap size is greater than the second gap size, it is determined that the bumper shaping surface collision verification is successful.

[0118] Specifically, if multiple functional component areas are located outside the pendulum collision area, and the first gap size is greater than the second gap size, it can be determined that the design of multiple functional component areas on the bumper molding surface is reasonable, and it can be determined that the bumper molding surface collision verification is successful. Making multiple functional component areas located outside the pendulum collision area and the first gap size greater than the second gap size can prevent multiple functional components such as fog lights, radars, sensors, and front cameras from being damaged when a low-speed collision occurs.

[0119] S105, projecting the air intake area of ​​the bumper styling surface to obtain the air intake area boundary and the radiator water tank boundary.

[0120] Specifically, after completing the collision check, the server can further perform a feasibility check on the air intake area of ​​the bumper molding surface. Specifically, the radiator and the bumper are assembled according to the vehicle coordinate system through a computer-aided three-dimensional interactive application (CATIA), and the air intake area of ​​the bumper molding surface is projected, thereby obtaining the air intake area boundary of the air intake area on the bumper molding surface, and the boundary of the radiator, that is, the boundary size of the heat dissipation area of ​​the radiator on the bumper molding surface, thereby obtaining the air intake area area according to the air intake area boundary, and obtaining the radiator area area according to the tank boundary.

[0121] S106, determining an air intake ratio according to an air intake area boundary and a radiator water tank boundary, and determining that the bumper molding surface air intake verification is successful when the air intake ratio is greater than or equal to a preset air intake ratio.

[0122] Specifically, after obtaining the air intake area and the radiator water tank area according to the air intake area boundary and the radiator water tank boundary respectively, the air intake ratio can be determined according to the ratio between the air intake area area and the radiator water tank area area, and when the air intake ratio is greater than or equal to the preset air intake ratio (such as 25%), the bumper styling surface air intake verification is determined to be successful.

[0123] The present embodiment provides a method for designing a bumper shaped surface, the method comprising: obtaining a vehicle layout drawing, and setting a vehicle coordinate system for the vehicle layout drawing, so as to extract multiple target component position information affecting the bumper shaped surface in the vehicle coordinate system from the vehicle layout drawing through three-dimensional software; constructing a design constraint model diagram of the bumper shaped surface according to the multiple target component position information, and designing the bumper shaped surface based on the design constraint model diagram, the design constraint model diagram being used to indicate the constraint conditions between the multiple target component position information through graphics; obtaining a functional component area, a pendulum collision area, a first gap size between the functional component and the structural hard point of the bumper, and a second gap size between the bumper and the anti-collision beam on the bumper shaped surface; if the functional component area is located outside the pendulum collision area and the first gap size is greater than the second gap size, determining that the bumper shaped surface collision verification is successful; projecting the air intake area of ​​the bumper shaped surface to obtain the air intake area boundary and the radiator water tank boundary; determining the air intake ratio according to the air intake area boundary and the radiator water tank boundary, and determining that the bumper shaped surface air intake verification is successful when the air intake ratio is greater than or equal to the preset air intake ratio. The following technical effects are achieved: a three-dimensional design constraint model diagram of the bumper styling surface is constructed through three-dimensional software, and the bumper styling surface is designed based on the design constraint model diagram, thereby limiting the design of the bumper styling surface so that it is designed on the basis of satisfying various constraint conditions in the design constraint model diagram, and performing collision verification and air intake verification after the design is completed.

[0130] Then, the server can combine the position information of multiple target components to generate multiple design constraints. The multiple design constraints include: the angle between the bottom position of the bumper and the tangent line drawn by the front wheel of the vehicle and the ground is greater than the approach angle; the bottom of the bumper is lower than the bottom surface of the anti-collision beam, and the distance between the bottom surface of the anti-collision beam is greater than the preset distance (such as 40 mm); the longitudinal position of the bumper is located after the front overhang boundary position, that is, the front end position of the bumper does not exceed the front overhang boundary position; the bumper air intake area covers the radiator area, that is, the bumper air intake area covers the boundary of the radiator area of ​​the radiator; multiple functional component areas are located outside the pendulum collision area, that is, multiple functional component areas must not be arranged in the pendulum collision area to avoid To prevent the vehicle from causing damage to multiple functional components such as fog lights, radars, sensors and front cameras when a low-speed collision occurs; the center point of the license plate area is located on the right side of the vehicle's longitudinal symmetry plane. The license plate area can overlap with the front anti-collision beam area to reduce the occupation of the bumper air intake area. The center point of the license plate area cannot be located on the left side of the vehicle's longitudinal symmetry plane. In addition, the license plate area can be set in two ways: the first vehicle license plate area and the second vehicle license plate area. The first vehicle license plate area is set to 520 mm × 140 mm, and the second vehicle license plate area is set to 320 mm × 160 mm.

[0131] Furthermore, multiple functional component areas and license plate areas should avoid overlapping with the bumper air intake area as much as possible, that is, minimize the occupation of the bumper air intake area. If there is no conflict between the functions implemented by the various functional component areas and license plate areas, they can overlap.

[0132] Figure 4 A schematic diagram of a bumper profile provided in an embodiment of the present application Figure 2 . Figure 4 This is the side view of the bumper styling surface, such as Figure 4As shown, the front overhang boundary position 410 is the distance from the center line of the front wheel axle to the frontmost point of the front of the vehicle, the approach angle 420 is the angle between the point where the front wheel of the vehicle contacts the ground 901 and the lowest point of the front end of the vehicle, the distance between the front anti-collision beam area 70 and the bottom of the bumper is the anti-collision beam bottom surface limiting boundary 430, the anti-collision beam bottom surface limiting boundary 430 is greater than the preset distance, and the area where the pendulum 440 collides with the bumper styling surface is the pendulum collision area.

[0133] S304, adding the design constraint conditions to the dimension model diagram to obtain the design constraint model diagram, and designing the bumper modeling surface based on the design constraint model diagram.

[0134] Specifically, the server may add a plurality of design constraint conditions to the dimension model diagram of the bumper styling surface, thereby generating a design constraint model diagram, and design the bumper styling surface based on the design constraint model diagram.

[0135] S305, obtaining the functional component area on the bumper molding surface, the pendulum collision area, the first gap size between the functional component and the structural hard point of the bumper, and the second gap size between the bumper and the anti-collision beam.

[0136] S306: If the functional component area is outside the pendulum collision area, and the first gap size is greater than the second gap size, it is determined that the bumper styling surface collision check is successful.

[0137] S307: Project the air intake area of ​​the bumper styling surface to obtain the air intake area boundary and the radiator water tank boundary.

[0138] S305-307 are similar to S103-S105, and will not be described in detail in this embodiment.

[0139] S308: Determine the area of ​​the first air intake region and the area of ​​the heat dissipation water tank region within the boundary of the heat dissipation water tank according to the boundary of the air intake region and the boundary of the heat dissipation water tank.

[0140] Specifically, the air intake area can be subdivided into a first air intake area within the boundary of the heat sink, and a second air intake area outside the boundary of the heat sink. Figure 5 A schematic diagram of a bumper profile provided in an embodiment of the present application Figure 3 .like Figure 5 As shown, there are multiple in-boundary air inlets 510 within the boundary of the radiator area 50, and multiple out-boundary air inlets 520 outside the boundary of the radiator area 50. Both the in-boundary air inlets 510 and the out-boundary air inlets 520 can be openings or grilles for guiding air into the engine compartment. The area of ​​the first air inlet region within the radiator boundary can be determined based on the multiple in-boundary air inlets 510.

[0141] S309: Determine the proportion of the first air intake area within the boundary of the heat sink according to the area of ​​the first air intake area and the area of ​​the heat sink area.

[0142] Specifically, the proportion of the first air intake area within the boundary of the cooling water tank can be determined according to the ratio between the area of ​​the first air intake region and the area of ​​the cooling water tank.

[0143] S310: If the first air intake area ratio is greater than or equal to the preset air intake ratio, it is determined that the bumper shape air intake verification is successful.

[0144] Specifically, if the first air intake area ratio is greater than or equal to the preset air intake ratio, it can be determined that the bumper shape air intake verification is successful.

[0145] S311: If the first air intake area ratio is less than the preset air intake ratio, determine the area of ​​the second air intake region outside the boundary of the cooling water tank.

[0146] Specifically, if the first air intake area ratio is smaller than the preset air intake ratio, the area of ​​the second air intake region outside the boundary of the cooling water tank may be determined based on a plurality of outside-boundary air intake inlets 520 .

[0147] S312: Convert the area of ​​the second air intake region to the area of ​​the third air intake region within the boundary of the heat dissipation water tank according to a preset conversion coefficient.

[0148] Specifically, the server can convert the area of ​​the second air intake region into the area of ​​the third air intake region within the boundary of the heat sink according to a preset conversion coefficient (such as 0.4). That is, if the air intake area within the boundary of the heat sink is insufficient, air can be taken in from multiple out-of-boundary air intake inlets 520 outside the boundary of the heat sink. However, since the air entering from the out-of-boundary air intake inlets 520 has a lower cooling effect on the engine, radiator and other cooling systems, the area of ​​the second air intake region can be multiplied by the preset conversion coefficient to convert it into the area of ​​the third air intake region within the boundary of the heat sink.

[0149] At this time, an air guide device may be further designed for the outer-boundary air inlet 520 so that the air entering from the outer-boundary air inlet 520 can enter the cooling water tank through the air guide device to cool the engine, radiator and other cooling systems.

[0150] S313: Determine a proportion of a second air intake area within a boundary of the heat sink according to the area of ​​the first air intake area, the area of ​​the third air intake area, and the area of ​​the heat sink area.

[0151] Specifically, the server can sum the areas of the first air intake area and the third air intake area to obtain the area of ​​the fourth air intake area, and determine the proportion of the second air intake area within the boundary of the cooling water tank according to the ratio between the area of ​​the fourth air intake area and the area of ​​the cooling water tank.

[0152] S314: If the second air intake area ratio is greater than or equal to the preset air intake ratio, it is determined that the bumper shape air intake verification is successful.

[0153] Specifically, if the second air intake area ratio is greater than or equal to the preset air intake ratio, it can be determined that the bumper shape air intake verification is successful.

[0154] Furthermore, in a possible implementation, a method for designing a bumper profile surface further includes: when the first gap size is smaller than the second gap size, adjusting the functional component area so that the first gap size is larger than the second gap size, thereby preventing the vehicle from causing damage to multiple functional components such as fog lights, radars, sensors, and front cameras when a low-speed collision occurs. When the air intake ratio is smaller than a preset air intake ratio, adjusting the bumper profile surface to increase the area of ​​the bumper air intake region until the air intake ratio is greater than or equal to the preset air intake ratio.

[0155] A method for designing a bumper styling surface provided in an embodiment of the present application constructs a dimension model diagram of the bumper styling surface according to multiple target component position information, combines the multiple target component position information to generate design constraints, then adds the design constraints to the dimension model diagram to obtain a design constraint model diagram, and designs the bumper styling surface based on the design constraint model diagram, fully considering multiple complex factors that need to be paid attention to in the design of the bumper styling surface, improving the design quality of the bumper styling surface, and reducing the number of repeated changes to the bumper styling surface in the later stage; according to the air intake area boundary and the radiator water tank boundary, determines the first air intake area ratio within the radiator water tank boundary, and if the first air intake area ratio is less than the preset air intake ratio, determines the second air intake area ratio outside the radiator water tank boundary. The area of ​​the second air intake area is calculated, and the area of ​​the second air intake area is converted to the area of ​​the third air intake area within the boundary of the radiator water tank according to a preset conversion coefficient. Then, according to the area of ​​the first air intake area, the area of ​​the third air intake area and the area of ​​the radiator water tank, the proportion of the second air intake area within the boundary of the radiator water tank is determined. Then, when the proportion of the second air intake area is greater than or equal to the preset air intake proportion, it is determined that the bumper shape air intake verification is successful, so that the design of the bumper air intake area is more reasonable, and sufficient air flow can be provided for the engine, radiator and other cooling systems; by preventing multiple functional component areas and license plate areas from overlapping with the bumper air intake area, the occupation of the bumper air intake area is reduced, and it is further ensured that the area of ​​the bumper air intake area meets the heat dissipation requirements of the engine, radiator and other cooling systems.
