[0028] The present application provides an automatic support method, device, terminal, and medium for a tire model. The method sets all facets on the tire model surface to an unsupported area, adds a honeycomb structure to the interior of the tire, and then adds intelligent support to the interior of the honeycomb structure. The unsupported area state of all facets on the tire model surface is cleared, and block support is generated for the areas corresponding to each identified planar facet of the tire model. The method of the present application can achieve lightweight tires and solve the problem of not being able to add multiple types of support to a tire model with one click.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following embodiments and the accompanying drawings are used to further describe the technical solutions in the embodiments of the present invention. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] As shown in FIG1 , it shows a flow chart of an automatic support method applicable to a tire model according to an embodiment of the present invention.

[0031] The automatic support method applicable to the tire model comprises:

[0032] Step S101: setting all patches on the tire model surface to a no-support area state.

[0033] The types of patches on the tire model surface include: plane patches and patterned patches.

[0034] Specifically, the tire model surface patches include: 1 pattern surface patch and 5 plane patches; among them, 4 plane patches of the 5 plane patches are side plane patches, and the remaining 1 plane patch is a bottom plane patch.

[0035] In a specific embodiment, the patterned surface patch is the patch pointed to by arrow A in Figure 2, and the plane patch includes: plane patch 1, plane patch 2, plane patch 3, plane patch 4 and plane patch 5 pointed to by arrows in Figure 3; wherein, the side plane patch includes: plane patch 2, plane patch 3, plane patch 4 and plane patch 5.

[0036] Optionally, when adding support to the tire model, support cannot be added to the area corresponding to the patch set to the unsupported area state.

[0037] Step S102: Using the identified bottom plane patch of the tire model as an opening surface, adding a honeycomb structure to the interior of the tire model, setting each honeycomb structure patch of the honeycomb structure to an unmarked state, and keeping all patches on the surface of the tire model in a state of no support area.

[0038] Optionally, the method for identifying the bottom plane patch of the tire model includes: identifying the plane patch with the largest area among all patches on the tire model surface, and using the plane patch as the bottom plane patch of the tire model. For example, as shown in FIG3 , the area corresponding to plane patch 1 in the tire model is the largest in the tire model, so plane patch 1 is identified as the bottom plane patch of the tire model.

[0039] Optionally, using the bottom plane patch of the identified tire model as an opening surface and adding a honeycomb structure to the interior of the tire model includes: using the bottom plane patch of the identified tire model as an opening surface and adding each honeycomb structure patch to the interior of the tire model with its normal direction as the extension direction.

[0040] Optionally, when adding support to the tire model, support may be added to the area corresponding to each honeycomb structure facet that is set to an unmarked state.

[0041] It should be noted that the honeycomb structure in the above embodiment is the honeycomb structure shown in FIG. 4 .

[0042] Step S103: generating intelligent supports for each honeycomb structure patch area set to an unmarked state in the tire model, so as to add intelligent supports to the interior of the honeycomb structure.

[0043] Optionally, the method for generating the intelligent support includes:

[0044] Cutting the honeycomb structure according to the set layer thickness to generate slices at each layer;

[0045] Generate corresponding support points for slices that meet the support point generation conditions, and generate SLA supports with truss structures as support bodies based on each support point.

[0046] Among them, SLA support is a support structure that uses the SLA (Stereolithography Appearance) process; Stereolithography mainly uses photosensitive resin as raw material, taking advantage of the property that liquid photosensitive resin will quickly solidify under the irradiation of ultraviolet laser beams. Photosensitive resin is generally liquid, and it immediately causes a polymerization reaction when irradiated with ultraviolet light of a certain wavelength (250nm~400nm), completing the curing; SLA focuses ultraviolet light of a specific wavelength and intensity onto the surface of the photocurable material, causing it to solidify from point to line, and from line to surface, thereby completing the drawing of a layer cross-section; in this way, layer by layer is superimposed to complete the printing of a three-dimensional entity; the advantages of SLA technology are fast molding speed and high surface smoothness and fineness of the produced entity.

[0047] Optionally, the number of slices generated in each layer by cutting the honeycomb structure is related to a set layer thickness.

[0048] It should be noted that the truss structure in this embodiment is shown in FIG5 ; the layer thickness is set according to actual needs and is not limited in the present invention.

[0049] Optionally, generating corresponding support points for slices that meet the support point generation conditions includes: obtaining redundant contours obtained by comparing the contours of the current layer slice with the previous layer slice; judging whether the inclination angle calculated by the maximum offset distance corresponding to the redundant contour and the set layer thickness is within the intelligent support angle range; if it is within the intelligent support angle range, generating the corresponding support points for the current layer slice; if it is not within the intelligent support angle range, not generating the support points for the current layer slice.

[0050] Optionally, each slice layer corresponds to a Z-axis height; the order of the slice layers is from small to large Z-axis heights corresponding to the slice layers; and the support points corresponding to the slice layers are generated according to the order of the Z-axis heights from small to large.

[0051] For example, the Z-axis height corresponding to the first layer of slices is the smallest, and the Z-axis height corresponding to the current layer of slices is greater than the Z-axis height corresponding to the previous layer of slices.

[0052] Optionally, the two-dimensional contour corresponding to the current layer slice and the two-dimensional contour corresponding to the previous layer slice are compared to obtain a redundant contour; wherein the redundant contour is an extra two-dimensional contour obtained by comparing the two-dimensional contour corresponding to the current layer slice and the two-dimensional contour corresponding to the previous layer slice.

[0053] Optionally, the method for obtaining the maximum offset distance includes: offsetting the redundant contour until no contour is left, where the offset value is the maximum offset distance; wherein the method for offsetting the redundant contour includes: compressing the area corresponding to the redundant contour; and the redundant contour is two-dimensional. Optionally, the intelligent support angle range is the angle range within which corresponding support points can be generated for the current layer slice.

[0054] Optionally, since a certain distance needs to exist between each support point, the number of support points corresponding to the current layer slice is also limited by the number of support points corresponding to all layer slices before the current layer.

[0055] For example, if the current layer is layer 7, the number of support points corresponding to the slices of layer 7 is limited by the number of support points corresponding to the slices of layers 1 to 6. This is because the support points corresponding to the slices of layer 7 need to be a certain distance away from the support points corresponding to the slices of layers 1 to 6.

[0056] It should be noted that the intelligent support angle range can be set according to actual needs, and the present invention does not limit this.

[0057] The following is an example of a method for generating corresponding support points for slices that meet the support point generation conditions, combined with the above embodiment:

[0058] Example 1: Generate multiple support points for the first layer of slices.

[0059] Compare the two-dimensional contour corresponding to the first layer of slices with the two-dimensional contour corresponding to the zero layer of slices to obtain a redundant contour. Since there is no zero layer of slices, it means that the zero layer of slices is empty, and the redundant contour obtained is the two-dimensional contour corresponding to the first layer of slices. Determine whether the inclination angle calculated by the maximum offset distance corresponding to the two-dimensional contour corresponding to the first layer of slices and the set layer thickness is within the intelligent support angle range. If it is within the intelligent support angle range, the support point of the first layer of slices is generated; if it is not within the intelligent support angle range, the support point of the first layer of slices is not generated.

[0060] Example 2: Generate multiple support points for the i-th slice.

[0061] Compare the 2D contour corresponding to the i-th slice with the 2D contour corresponding to the i-1th slice to obtain a redundant contour. Determine whether the tilt angle calculated from the maximum offset distance corresponding to the redundant contour and the set slice thickness is within the intelligent support angle range. If so, support points are generated for the i-th slice; if not, no support points are generated for the i-th slice.

[0062] In this embodiment, i represents the serial number of each layer; the smaller i is, the smaller the Z-axis height corresponding to the i-th layer slice is; the maximum value of i is the number of slices in each layer generated by cutting the honeycomb structure; the maximum value of i is related to the set layer thickness.

[0063] It should be noted that the present invention does not offset the redundant contours in the actual model until there are no contours.

[0064] Step S104: clearing the unsupported area state of all patches on the surface of the tire model, and generating block support for the area corresponding to the identified large plane patch of the tire model.

[0065] Optionally, the method for identifying the large plane patch of the tire model includes: jointly identifying a plane patch on the tire model surface whose normal direction is consistent with the normal direction of the identified bottom plane patch of the tire model and the bottom plane patch as a large plane patch.

[0066] For example, the bottom plane patch of the tire model is the plane patch pointed to by arrow C in Figure 6, and the plane patch on the surface of the tire model whose normal direction is consistent with the normal direction of the bottom plane patch of the tire model is the patch pointed to by arrow B in Figure 6. This patch and the bottom plane patch are jointly identified as a large plane patch, and the area corresponding to this patch and the area corresponding to the bottom plane patch are the areas corresponding to the large plane patch. Then, block support is generated for the area corresponding to the large plane patch, and the block support is the support pointed to by arrow D in Figure 6.

[0067] Optionally, the block support adopts SLA support.

[0068] It should be noted that the addition of intelligent supports to the honeycomb structure and the generation of block supports in the above embodiment are intended to prevent material from falling during the printing process, which would affect the success rate of tire model printing. The following will describe in detail the automatic support method applicable to tire models in conjunction with the above embodiment:

[0069] First, the patterned surface patch indicated by arrow A in Figure 2 and planar patches 1 through 5 in Figure 3 are set to an unsupported area. The bottom patch of the identified tire model, namely planar patch 1, is used as the open surface. The normal direction of planar patch 1 is determined and used as the extension direction to add a honeycomb structure to the tire interior. This honeycomb structure contributes to tire lightweighting.

[0070] To prevent material from sagging during printing, which could affect the success rate of tire model printing, smart supports need to be added to the honeycomb structure. Since the honeycomb structure's individual patch areas are unmarked, and planar patches 1 through 5 are unsupported, during the smart support addition process, smart supports are generated for the unmarked honeycomb patch areas, while no supports are generated for planar patches 1 through 5. This prevents supports from being generated on the patterned patch, which could affect the surface support of the patterned patch after printing.

[0071] After generating the intelligent support, the unsupported area state of plane patch 1 to plane patch 5 is cleared, and as shown in FIG6 , the patch on the surface of the tire model whose normal direction is consistent with the normal direction of the bottom plane patch of the tire model is the patch pointed to by arrow B in FIG6 , and this patch and the bottom plane patch are jointly identified as plane patches, and then block support as shown in FIG6 is generated for the area corresponding to this patch and the area corresponding to the bottom plane patch.

[0072] Similar in principle to the above embodiment, the present invention provides an automatic supporting device suitable for a tire model.

[0073] The following provides specific embodiments in conjunction with the accompanying drawings:

[0074] FIG7 is a schematic structural diagram of an automatic supporting device for a tire model according to an embodiment of the present invention.

[0075] The automatic supporting device 7 suitable for the tire model comprises:

[0077] a honeycomb structure adding module 72, connected to the state setting module 71, configured to use the identified bottom plane patch of the tire model as an opening surface, add a honeycomb structure to the interior of the tire model, set each honeycomb structure patch of the honeycomb structure to an unmarked state, and keep all patches on the surface of the tire model in a state of no support area;
