Description

Technical Field

[0001] The invention relates to the technical field of model construction splicing, and in particular to a slice-type assembly model structure and a manufacturing method thereof. Background Art

[0002] Existing assembly models are generally in the form of flat puzzles, and their structure generally includes a mounting plate with a block slot arranged on the mounting plate. The blocks are moved in the block slot to form specific patterns. The assembly mode of this type of structure can only be used to train the operator's two-dimensional spatial imagination ability, and cannot well train the operator's three-dimensional spatial imagination ability. The existing assembled three-dimensional models are basically similar assembly toys such as building blocks or jigsaw puzzles, all of which are assembled into three-dimensional models with three-dimensional block components of various shapes and sizes. The assembly mode of this type of structure can only predictably combine and assemble the original state of the model with three-dimensional block components, lacking the perception of two-dimensional space and the expansion of thinking, and the materials used are mostly plastic and wood materials. Therefore, there is a gap in the market and technology, and there are very few assembly model structures that can simultaneously meet the two-dimensional and three-dimensional training capabilities.

[0003] In the model assembly process, a known model is often required to be produced and processed into various assembly components through equipment. Concave and convex points, plug interfaces and other structures are set on the assembly components to build the model. The production and processing accuracy is difficult to control, and there are nesting mismatches, which are easy to loosen, or the relative positions of the components are stuck after connection. Disassembly requires strong force, which can easily cause damage to the components and is difficult to reuse for a long time. Some assembly components are even connected to build the model structure by bonding with glue or other adhesives. The reuse rate is extremely low. At the same time, the safety is low and it is not suitable for children. Summary of the invention

[0013] 2) Based on the maximum outline of the plane image, the corresponding three-dimensional model is reduced inward and then cut in parallel to obtain a group of contour plates with a certain thickness. This group of contour plates is recorded as a2, and the reduction ratio is recorded as x,0 <x<1;

[0014] 3) Continue to cut parallel to the corresponding three-dimensional model after the contour on the plane is reduced inward, and obtain a group of contour plates with a certain thickness. This group of contour plates is recorded as a3, and the reduction ratio is recorded as y, 0 <y<1;

[0015] 4) Continue to repeat step 3) until a group of contour plates with a certain thickness is obtained. This group of contour plates is recorded as a i , the reduction ratio is recorded as z,0 <z<1。

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention 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 invention and are not intended to limit the present invention.

[0039] See also Figure 1-10A slice-type assembly model structure, the embodiments of the present invention all take a dinosaur model structure as an example. Of course, the model structure is not limited to dinosaur models, and can also be other biological, plant or building models, etc. The specific selection will not limit the present invention. The model structure includes a structural axis 1 and a plurality of contour plates 2 cut from a three-dimensional model in a slice manner. Each corresponding position on the contour plate 2 is provided with a through hole 3 that is compatible with the cross-sectional size of the structural axis 1. The structural axis 1 is provided with a locking mechanism 4. The structural axis 1 passes through the contour plates 2 obtained by the slicing method in sequence through the through holes 3, and one or more matching contour plates 2 are nested on the outward side of the locking structure 4. In actual use, the contour plates 2 obtained by slicing can be but are not limited to metal sheets, plastic sheets or cardboard sheets, all of which are made of environmentally friendly materials and can be significantly degraded. It is preferably placed in a random order before assembly to increase the fun and challenge of model assembly. When the model structure needs to be assembled, the contour plates 2 are assembled into a three-dimensional model in the order of slicing by the structural axis 1, such as Fig.10 As shown, the assembly operation is completed. Especially for children, the disordered contour plates 2 can also enhance the training of children's plane and space logical thinking ability, which has important guiding and educational significance.

[0040] The three-dimensional model will obtain multiple contour plates 2 through slicing. The preferred slicing method is to obtain the contour plates 2 by cutting them in parallel in the same displacement direction, that is, the contour plates 2 can be obtained by cutting with horizontal displacement, vertical displacement or displacement at any angle. In this embodiment, the contour plates 2 are obtained by slicing with horizontal displacement, so there are a certain number of contour plates 2 on both sides of the horizontal plane from the center line of the model structure. The dinosaur model used in this embodiment is sliced ​​in the above-mentioned slicing method to obtain the contour plate result. The slicing method will not be repeated. The specific number of slicing times and the number of contour plates obtained by slicing are based on the actual model structure, and are not limited to the specific number and number in this embodiment. First, the model structure is sliced ​​4 times to obtain 4 groups of contour plates a1, a2, a3, and a4 respectively. At this time, the horizontal planes from the center line of the model structure to the left and right sides contain these 4 groups of contour plates. For the convenience of observation, the structural schematic diagrams of the contour plates a1, a2, a3, and a4 on the left side of the model are shown respectively, as shown in FIG. Figure 1 At the same time, after the last 4 slicing operations, 3 more slicing operations are carried out to obtain 3 sets of contour plates a5, a6, and a7, which exist on the horizontal planes on the left and right sides of the model construction center line respectively. The structural schematic diagrams of the 3 sets of contour plates a5, a6, and a7 on the left side of the model are shown respectively, as shown in FIG. Figure 2 As shown in the figure, it can be seen that the three groups of contour plates on the left are discontinuous; finally, slicing the remaining part of the dinosaur model will obtain three groups of contour plates a8, a9, a 10, with the three sets of contour plates a8, a9, a 10 The structural schematic diagrams are shown respectively, as Figure 3 shown.

[0041] At this point, the dinosaur model structure has been completely sliced ​​to obtain each group of contour plates 2, directly reducing the three-dimensional model to contour plates 2 mainly in two-dimensional space, avoiding the situation where the plates are not accurately matched due to separate production and processing by equipment outside the model, facilitating disassembly and assembly, and improving the reuse rate and stability of the model structure. In another embodiment, it is further preferred that the thickness of each group of contour plates 2 is equal, so that the assembly of the contour plates 2 is more neat and uniform, but it increases the difficulty of identification for the operator, thereby adding more fun.

[0042] In practical applications, the preferred model structure may include multiple structural axes 1, and each structural axis 1 is respectively adapted to a corresponding through hole 3, and is not limited to the number of structural axes 1 and through holes 3 in this embodiment. Figure 1 Each group of contour plates 2 of the dinosaur model shown is provided with two through holes 3, including a first through hole 31 located at the body of the dinosaur model and a second through hole 32 located at the head of the dinosaur model. At the same time, there is a structural axis 1 with a cross-sectional size adapted to the through hole 3. The structural axis 1 includes a first structural axis 11 adapted to the first through hole 31 and a second structural axis 12 adapted to the second through hole 32. The structure of the first structural axis 11 is as shown in FIG. Figure 4 As shown, the first structural shaft 11 includes an inner shaft portion 111 and an outer shaft portion 112, and the first through hole 31 adapted to the inner shaft portion 111 is shown in FIG. Figure 1 On the contour plate 2 shown, the first through hole 31 adapted to the outer shaft portion 112 is shown. Figure 2 and 3 On the contour plate 2 shown.

[0043] The first structural shaft 11 is provided with a locking mechanism 4, which includes a locking hole 41 and a locking member 42. The locking hole 41 is provided at both ends of the first structural shaft 11, and the locking member 42 can be embedded in and separated from the locking hole 41. In this embodiment, when the locking member 42 is embedded in the first structural shaft 11, as shown in FIG. Figure 5 As shown, it is easy to disassemble and manufacture, and improves the reusability and stability of the model structure.

[0044] like Figure 6 As shown, the second through hole 32 at the head position of the dinosaur model is matched with the second structural axis 12, and the second through hole 32 matched with the cross-sectional size of the second structural axis 12 is shown. Figure 1 On the contour plate 2 shown in the figure, in this embodiment, the side view structure when the locking element 42 is embedded in the second structural axis 12 is as shown in FIG. Figure 7The first structural axis 11 and the second structural axis 12 are respectively used to fix each contour plate 2, avoiding the need to directly set concave and convex points and plug-in interfaces on the contour plate 2, thereby reducing processing costs and the probability of damage. It is worth mentioning that since the structural axis 1 plays a stabilizing role in the through assembly of the contour plate and is tightly matched with the through hole 3, the shape of the structural axis is not limited to the shape mentioned in this embodiment, and can also be cylindrical, cross-shaped, etc.

[0045] The preferred contour plate 2 has a printed layer sprayed on each surface, and the printed layer is provided with a pattern and / or color, and the outer side surface of the contour plate 2 spliced ​​in the order of slices forms a continuous pattern and / or color. To avoid interference with the observation of the line drawing, the printed layer is not shown in the attached figure. Since it is equipped with a printed layer and the pattern and / or color thereon, the model construction operator can identify the elements of the pattern and / or color of the printed layer of each contour plate 2 during the assembly process, which is particularly effective in enabling children to understand and recognize color gradients and layering, enriching their imagination, and the model construction has rich colors and a strong three-dimensional sense. After the complete assembly combination, a continuous pattern and / or color will be formed, which will make the model construction more vivid and realistic, and increase the sense of experience.

[0046] like Figure 8 As shown in the side view structural diagram of the assembled state of the contour plates a1 to a4, the first structural axis 11 and the second structural axis 12 are used to respectively penetrate the contour plate 2 obtained by the slicing method through the first through hole 31 and the second through hole 32, and then the locking piece 42 is respectively inserted into the first through hole 31 and the second through hole 32, as shown in FIG. Fig. 9 As shown, the through contour plate 2 is fixedly assembled, and the locking structure 4 formed by the embedded locking element 42 will be nested with the remaining one or more contour plates 2, such as Fig.10 As shown, in this embodiment, the remaining contour plate 2 is Figure 2 The three groups of contour plates a5, a6, and a7 at the head position of the dinosaur model, and Figure 3 A8, A9, A in the structure of the dinosaur model 10 .

[0047] The present invention also provides a method for making a sliced ​​assembly model structure, such as Fig.11 As shown, the manufacturing method includes a slicing method, S100, and the slicing method specifically includes the following steps:

[0048] 1) Project the three-dimensional model onto a plane to obtain the plane view of the model. Cut parallel to the three-dimensional model corresponding to the maximum outline of the plane view to obtain a set of contour plates 2 of a certain thickness. The contour plate is recorded as a1. Slice the dinosaur model structure as a prototype. For easy observation, the contour plate of the left view of the model is as follows: Figure 1As shown, obtain the contour plate piece a1 corresponding to the maximum contour;

[0049] 2) On the basis of the maximum contour of the said plan view, perform parallel cutting on the corresponding solid model after inward proportional reduction, to obtain a group of contour plate pieces with a certain thickness. This group of contour plate pieces is denoted as a2, and the reduction ratio is denoted as x, where 0 < x < 1. As Figure 1 shown, the obtained group of contour plate pieces a 2； ,

[0050] 3) Then, continue to perform parallel cutting on the corresponding solid model after inward proportional reduction on the basis of the previous contour on the said plan view, to obtain a group of contour plate pieces with a certain thickness. This group of contour plate pieces is denoted as a3, and the reduction ratio is denoted as y, where 0 < y < 1. As Figure 1 shown, the obtained group of contour plate pieces a2;

[0051] 4) Continue to repeat step 3) until finally obtaining a group of contour plate pieces with a certain thickness. This group of contour plate pieces is denoted as a i , and the reduction ratio is denoted as z, where 0 < z < 1. In this embodiment, continuing to repeat step 3) will continue to obtain subsequent contour plate pieces a4 to a 10 , among which the 3 groups of contour plate pieces a5, a6, and a7 obtained are in a discontinuous state. The finally obtained group of contour plate pieces is shown in Figure 3 the contour plate piece a 10 .

[0052] In practical applications, when the reduction ratios x, y,..., z of the above-mentioned plan view are not equal, the sizes of the multiple contour plate pieces 2 obtained by slicing will appear uneven, the structure of the assembled model will appear abrupt and unnatural, and the assembly difficulty will be greatly increased. Preferably, the reduction ratios x = y =... = z of the above-mentioned plan view, and the thicknesses of the obtained contour plate pieces a1, a2, a3... a i are the same, that is, the thicknesses of the contour plate pieces a1, a2, a3... a 10 in this embodiment are equal, making the assembly more neat and unified, but it will increase the recognition difficulty of the operator to a certain extent, thus increasing more fun.

[0053] The manufacturing method of the present invention not only includes the above-mentioned S100, slicing method, but also includes:

[0054] S101, drilling holes in the plate pieces. Use drilling equipment to drill through holes 3 at the corresponding positions in the same displacement direction of each contour plate piece 2 obtained by the slicing method; during specific operation, stack the contour plate pieces a1, a2, a3, a4 obtained by the slicing method for assembly, as Figure 8As shown, drilling equipment is used to align the stacked contour plates a1, a2, a3, and a4 to drill through holes 3 at corresponding positions, respectively drilling the first through hole 31 and the second through hole 32. Similarly, the remaining contour plates 2 are stacked and drilled to drill through holes 3.

[0055] S102, spray printing to form a printing layer;

[0056] S103, shaft assembly, using a structural shaft 1 with a locking structure 4 to sequentially penetrate the contour plate 2 obtained by slicing through the through hole 3, until the contour plate 2 reaches the locking hole 41 on the structural shaft 1, such as Fig. 9 As shown, a matching lock 42 is assembled on the lock hole 41, and then the remaining one or more contour plates 2 are nested and tightly fitted into the lock 42, as shown in FIG. Fig.10 As shown, the model assembly is completed.

[0057] Before step S103, it also includes spraying a printing layer on the contour plate 2. The printing layer can be compounded or / printed on each side of the contour plate by a printing machine, and a pattern and / or color is provided on the printing layer. This increases the aesthetics of the model structure and allows the operator to identify the elements of the pattern and / or color of the printing layer on each side of each contour plate 2 during the assembly process. The model has rich colors and a strong three-dimensional sense. After the complete assembly combination, a continuous pattern and / or color will be formed, which will make the model structure more vivid and lifelike, increase the sense of experience, and have the characteristics of educational, entertainment and decoration.
