The specific modeling execution process is as follows Figure 1 shown.

[0023] An embodiment of the present invention provides a modeling method for interior and exterior trims. Figure 1 A flowchart of a modeling method for interior and exterior trims provided by an embodiment of the present invention, such as Figure 1 As shown, the method includes: Step 102: Acquire the set standard structure data.

[0024] In the embodiment of the present invention, each step may be performed by a computer device. For example, the computer device includes a computer or a tablet computer.

[0025] In an embodiment of the present invention, standard structure data can be added to the design platform, wherein the standard structure data can be the A-pillar interior panel, the installation point structure, and the instrument panel matching structure according to the best practices of previous projects to form a solidified matching relationship.

[0026] Figure 2 A schematic diagram of a standard structure data provided by an embodiment of the present invention, such as Figure 2As shown, the standard structural data may include the root and main body connection thickness A1, the gradual thinning height A2, the root inner rounded corner A3, the transition surface angle A4, the gradual thinning angle A5, the draft angle A6 and the buckle seat thickness A7.

[0027] Table 1 is a standard structure data table, as shown in Table 1 below.

[0028] Table 1 As shown in Table 1 above, when the interior and exterior trims are polypropylene (PP) parts and the exterior is painted, when the thickness of the leather grain is T=2.0~2.7, the recommended value of A1 is 0.8; when the interior and exterior trims are acrylonitrile butadiene styrene (ABS) and other material parts, when the thickness is T=2.0~2.4, the recommended value of A1 is 0.8; when the interior and exterior trims are PP parts, when the thickness of the leather grain is T≥2.8, the recommended value of A1 is 1.0; when the interior and exterior trims are ABS and other material parts, when the thickness is T≥2.4, the recommended value of A1 is 1.0.

[0029] Step 104: Model the interior and exterior trim parts according to the standard structure data to generate an initial model.

[0030] In the embodiment of the present invention, the interior and exterior trims include parts with consistent modeling requirements such as the A-pillar interior panel, the B-pillar interior panel or the C-pillar interior panel in the automobile interior.

[0031] In the embodiment of the present invention, the modeling of the A-pillar interior trim panel is taken as an example for description.

[0032] Step 106: Arrange the mounting point structure of the initial model and the sheet metal connection according to the standard structure data to generate a first model.

[0033] In the embodiment of the present invention, standard structure data can be called from the design platform.

[0034] In the embodiment of the present invention, the standard structure data may further include the spacings B1 and B2 between the installation point structures.

[0035] In an embodiment of the present invention, the installation point structure for connecting the initial model and the sheet metal can be automatically arranged. Specifically, according to the distances A1 and A2 from the boundary of surface A and the spacings B1 and B2 between the installation point structures, the installation point structure is automatically called from the design center, and corresponding adjustments and arrangements are automatically made. In addition, distances, moving objects, array features, offset surfaces, replacement surfaces, trimmed bodies, and stitching are automatically measured, thereby improving modeling efficiency and avoiding inconsistent designs by different personnel and subjective errors that may occur in manual arrangements.

[0036] Figure 3 A schematic diagram of a mounting point structure for arranging an initial model and connecting a sheet metal is provided in an embodiment of the present invention, such as Figure 3 As shown, A1' is the first boundary distance, A2' is the second boundary distance, B1 and B2 are the spacings between the mounting point structures, wherein B1 is the first spacing distance, and B2 is the second spacing distance.

[0037] Step 108: Arrange the snap-fit ​​structure between the first model and the instrument panel according to the standard structure data to generate a second model.

[0038] In an embodiment of the present invention, the standard structural data may also include distance requirements C1, C2, C3, C4, C5 and C6 from the A surface, where C1 is the first A surface distance, C2 is the second A surface distance, C3 is the third A surface distance, C4 is the fourth A surface distance, C5 is the fifth A surface distance, and C6 is the sixth A surface distance.

[0039] In the embodiment of the present invention, the snap-fit ​​structure between the first model and the instrument panel can be automatically arranged. Figure 4A , 4B A schematic diagram of a snap-in structure for arranging a first model and an instrument panel according to an embodiment of the present invention, according to calling the snap-in structure from the design platform (see Figure 4A ), the specific choice of the card structure can be selected according to the actual situation based on the structure required by the A-pillar upper trim. Based on the boundary of the A-surface of the model, according to the distance requirements C1, C2, C3, C4, C5 and C6 from the A-surface, the card structure matching the instrument panel is automatically arranged (see Figure 4B ), and measure distances, move objects, array features, offset faces, replace faces, trim bodies, and stitch, which improves efficiency and avoids subjective errors that may occur in manual layout. It does not involve inputting the dashboard, but only separately matching the structure that is snapped to the dashboard on the A-pillar upper trim.

[0040] Step 110: Perform a modeling operation on the second model to generate an interior and exterior trim model.

[0041] In the embodiment of the present invention, the modeling operation includes a distance measurement operation, an object movement operation, an array feature operation, an offset surface operation, a surface replacement operation, a body trimming operation, and a stitching operation.

[0042] In an embodiment of the present invention, when the interior and exterior trim include an A-pillar interior panel, the distance measuring operation includes: measuring the model structure data of the second model, the model structure data including: a first boundary distance A1' and a second boundary distance A2' of the A-surface boundary distance, a first spacing distance B1 and a second spacing distance B2 of the mounting point structure spacing, and a first A-surface distance C1, a second A-surface distance C2, a third A-surface distance C3, a fourth A-surface distance C4, a fifth A-surface distance C5 and a sixth A-surface distance C6 from the A-surface. The program measures the first boundary distance A1' and the second boundary distance A2' of the boundary distance of surface A, the spacings B1 and B2 between the mounting point structures, and the distances C1, C2, C3, C4, C5, and C6 from surface A by calling the measure distance command (the command can calculate the distance between two objects, the radius of a cylinder, the length of a curve, and the radius of an arc or a circle. The basic principle is: by analyzing the geometric properties of two objects, calculating the straight-line distance between them, the actual length of a curve, and the radius of an arc, a circle, or a cylinder, so as to meet the requirements of dimension measurement and verification and ensure accuracy).

[0043] In the embodiment of the present invention, the object moving operation includes: displacing or rotating the model structure data according to the standard structure data. The program completes the corresponding adjustment and arrangement of the mounting point structure and the clamping structure by calling the move object command (the command can be used to reposition the object in the component, and the command can be used to move the object a specific distance along a given vector, toward a given vector, between two points, or along the X, Y and Z directions of the reference coordinate system (CSYS), and can move the object along a specified vector and rotate the object around a specified vector. The basic principle is that by defining the parameters of displacement and rotation, the object in the component can be accurately repositioned, including operations such as moving along a specific vector, rotating, and independently moving sub-objects).

[0044] In an embodiment of the present invention, the array feature operation includes: generating multiple feature instances by specifying the array boundary, instance direction, rotation angle, and variation parameters, so as to copy and arrange multiple installation point structures and snap-in structures according to the multiple feature instances. The program copies and arranges multiple installation point structures and snap-in structures by calling the array feature command (the command allows different types of feature arrays to be created by setting the array boundary, instance direction, rotation angle, and variation options, such as linear, circular, or polygonal arrays. The basic principle is: generating multiple feature instances by specifying the array boundary, instance direction, rotation angle, and variation parameters, thereby achieving feature copying and arrangement, and is often used to create regularly distributed structural elements, such as linear arrays, circular arrays, or polygonal arrays).

[0045] In the embodiment of the present invention, the offset surface operation includes: moving or extending one or more surfaces along the surface normal direction at a specified positive or negative distance, changing the surface position of the geometric body, so as to offset some surfaces of the mounting point structure or the clamping structure to the A-pillar interior panel, and generate an offset structure. Among them, the program offsets some surfaces of the mounting point structure or the clamping structure to the A-pillar interior panel by calling the offset surface command (the command allows one or more surfaces to be offset along the surface normal direction at a specified positive or negative distance, provided that the topology of the body does not change, and its basic principle is: by moving or extending one or more surfaces along the surface normal direction at a specified positive or negative distance, thereby changing the surface position of the geometric body without changing the overall topological structure of the body).

[0046] In the embodiment of the present invention, the surface replacement operation includes: adjusting the surface features of the second model without changing the overall topological structure of the body, so as to replace the unnecessary surface in the offset structure with the required surface. The program replaces the unwanted surface obtained by the offset with the required surface by calling the replace surface command (the command allows one or more faces or a single reference plane to replace a group of faces, and its basic principle is: by selecting an existing face and replacing it with a new geometric face, it is possible to adjust or modify specific surface features without changing the overall topological structure of the body to meet the design requirements).

[0047] In the embodiment of the present invention, the trimming operation includes: trimming off the portion of the offset structure that exceeds the A-pillar interior panel, and retaining the portion overlapping with the A-pillar interior panel. The program calls the trim body command (the command allows one or more target bodies to be trimmed by a face or plane, and the user can specify the body part to be retained and the part to be discarded. The trimmed target body will be displayed as the shape of the trimmed geometric element. The basic principle is: by using a face or plane to interact with the target body, the retained or discarded part can be specified, thereby modifying the appearance or structure of the target body according to the shape of the trimmed geometric element, which is usually used to accurately adjust the geometric shape) to trim off the unnecessary portion of the offset structure that exceeds the A-pillar interior panel, and retain the portion overlapping with the A-pillar interior panel.

[0048] In an embodiment of the present invention, the stitching operation includes: merging the boundary lines of multiple adjacent or intersecting surfaces or solid models into a continuous surface or entity, so as to merge the mounting point structure and / or the clip structure with the A-pillar interior panel into an interior and exterior trim model. The program calls the stitching command (the command allows two or more sheets to be connected into a new single sheet. If these sheets surround a closed volume, a solid body will be constructed. The gap between the selected sheets must not exceed the specified tolerance, otherwise the result will be a sheet. The basic principle is: by merging the boundary lines of multiple adjacent or intersecting surfaces or solid models into a continuous surface or entity, the gaps or discontinuous surfaces in the model are eliminated, ensuring smooth connection under limited boundary conditions, so as to maintain geometric consistency and continuity during subsequent processing or analysis) to merge the mounting point structure or the clip structure with the A-pillar interior panel into a solid (interior and exterior trim model).
