Description

Technical Field

[0001] This application relates to the fields of handicrafts, cultural products, and interlocking toys, and in particular to a handmade interlocking three-dimensional model with a novel interlocking structure. Background Technology

[0002] Currently, most handmade interlocking 3D models on the market (such as 3D origami, interlocking toys, etc.) are made of paper materials. Their joints are usually supported by a single connector when the model is in a 3D structure, or by bending or pressing to form an integral crease at the connector, so as to achieve folding and storage and 3D unfolding.

[0003] For example, the earlier patent application CN111890833B disclosed a method of manually assembled three-dimensional origami. This method achieves the transformation between a three-dimensional and flat state through the movable connection of the origami base, origami connectors, and origami body. The origami body uses a single, integrated origami support as a support for the second origami board in its three-dimensional structure. However, this connection method, which relies on material flexibility, still has certain shortcomings: when using rigid materials such as acrylic or rigid plastic, the materials themselves are relatively hard and lack flexibility, making it difficult to fold at the joints. After repeated bending, breakage or permanent deformation can easily occur, leading to decreased model stability and a shortened lifespan. Furthermore, most existing models have limited functionality, lack expandability, and are difficult to integrate electronic components to enhance interactivity and aesthetics.

[0004] Therefore, there is an urgent need for a new type of hand-assembled three-dimensional model that is structurally stable, uses a wide range of materials, and supports functional expansion. Summary of the Invention

[0005] This application provides a novel interlocking 3D model to solve the problem that in existing interlocking 3D models, when a single connector is used as a support at the model connection point, the connection point is not easy to fold, and after repeated bending, it is prone to breakage or permanent deformation, resulting in decreased model stability and shortened service life.

[0006] This application provides a hand-assembled three-dimensional model with a novel splicing structure, including:

[0014] Preferably, the first splicing structure includes:

[0018] Preferably, when there are multiple first protrusion structures, a second mating groove is provided between two adjacent first protrusion structures, and a second protrusion structure that mates with the second mating groove is provided on the first splicing base and / or the second splicing base.

[0019] Preferably, when the origami body is in a three-dimensional state, the first splicing base and the second splicing base are spliced ​​into a planar whole through corresponding protrusion structures and matching grooves.

[0020] Preferably, the adapter plate is disposed at the connection between the first splicing base and the second splicing base. The adapter plate is provided with a first / second through slot for the first / second protrusion structure to pass through, and both the first splicing base and the second splicing base are provided with splicing parts for connecting with other components on the side away from the adapter plate.

[0021] The length of the first through slot and the second through slot is less than or equal to the length of the corresponding protrusion structure.

[0022] Preferably, when the length of the first through slot and / or the second through slot is less than the length of the corresponding protrusion structure:

[0023] One end of the first through slot is provided with an oblique extension slot to facilitate its interlocking with the first protrusion structure;

[0024] The second through slot has movable holes at both ends, the diameter of which is larger than the width of the second through slot, so as to facilitate its insertion and connection with the second protrusion structure.

[0025] The first protruding structure has a first snap-fit ​​groove that can limit the position of the adapter plate;

[0026] The second protrusion structure has a second snap-fit ​​groove on both sides that can limit the position of the adapter plate.

[0027] Preferably, it also includes an origami outer body, which includes a first outer panel and a second outer panel, the first outer panel and the second outer panel being respectively disposed on opposite sides of the origami connector.

[0028] Preferably, the upper connecting plate includes a first connecting plate and a second connecting plate;

[0035] The beneficial effects of this application are as follows:

[0036] The novel interlocking three-dimensional model of this application, by utilizing the mechanical interlocking of the corresponding protrusions and matching grooves in the first interlocking structure, as well as the rigid support of the adapter plate, eliminates the dependence on the flexibility of materials, allowing the model to be made of hard materials such as acrylic and hard plastic. This solves the problem of breakage and glue separation caused by repeated folding of traditional paper models, and significantly improves the durability and service life of the model.

[0037] Furthermore, by setting the first splicing structure on both sides of the interlayer component, the interlayer component in three-dimensional state is provided with external closed protection. Combined with the planar support provided by the interlayer support plate, the three-dimensional shape is ensured to be accurate and not easily deformed. At the same time, it provides a hollow interlayer structure that can be filled for the interlayer component, which is better than the existing solution that relies on a single support component.

[0038] In particular, by creating a hollow layer between the origami connector and the origami body, an ideal installation space is provided for integrating electronic components such as LED light panels and voice broadcasting elements, thus expanding the functionality and interactivity of the model.

[0050] The technical solutions of this application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] The following is combined with Figure 1-5 This describes a hand-assembled three-dimensional model with a novel splicing structure provided in the embodiments of this application.

[0052] Reference Figure 1 and Figure 2 As shown in the embodiment of this application, the hand-assembled three-dimensional model with a novel splicing structure mainly includes an origami connector 100, an origami body 200, and an origami outer decoration 300. The origami body is connected to the origami connector, and when the origami connector rotates around its own rotation center, it can stretch the origami body into a three-dimensional state or compress the origami body into a flat state.

[0053] Please continue to refer to Figure 3 ,like Figure 3 As shown, it is a partial assembly structure diagram of the origami connector and the origami body in this application;

[0054] In some specific embodiments, the origami connector 100 includes an upper connecting plate, a lower connecting plate, and a support plate 105. In this embodiment, the upper connecting plate further includes a first connecting plate 101 and a second connecting plate 102, and the lower connecting plate includes a third connecting plate 103 and a fourth connecting plate 104. The first connecting plate 101, the second connecting plate 102, the third connecting plate 103, and the fourth connecting plate 104 are all rotatably connected through the support plate 105, that is, they can rotate with their respective connection points with the support plate 105 as the rotation center. The upper connecting plate and the lower connecting plate are spaced apart at the upper and lower ends of the support plate 105, so that a hollow layer that can be used for wiring or accommodating some electronic components is formed between the upper connecting plate and the lower connecting plate.

[0055] Please continue to refer to Figure 4 ,like Figure 4 As shown, it is a partial assembly diagram of the interlayer structure and the first splicing structure in this application;

[0056] In some specific embodiments, the origami body includes a first folding board 201, interlayer components, a first splicing structure 203, and multiple individual boards 205; one end of the first folding board 201 is inserted into the connection between the first connecting plate 101 and the second connecting plate 102 and passes through the first connecting plate 101 and the second connecting plate 102 before abutting against the outer surface of the third connecting plate 103 or the fourth connecting plate 104; one or more interlayer components are provided, each interlayer component includes two second folding boards 202 symmetrically arranged on both sides of the first folding board 201. When multiple sets are provided, the multiple sets of interlayer components are sequentially layered from bottom to top, and an interlayer support plate 204 is also provided between adjacent two sets of interlayer components to provide support for the upper components. A third splicing structure similar to or the same as the first splicing structure is also formed between the interlayer support plate 204 and the first folding board 201 to facilitate compression and folding;

[0057] Please continue to refer to Figure 5 ,like Figure 5 As shown, it is a schematic diagram of a first splicing structure provided in an embodiment of this application;

[0058] In some specific embodiments, the first splicing structure is used to connect the two ends of two second folded cardboard 202 in the same group. The first splicing structure includes a first splicing base 2031, a second splicing base 2032, and a transition plate 2033. The first splicing base 2031 is provided with at least one first protrusion structure 2034, and the second splicing base 2032 is provided with a first mating groove 2036 that cooperates with the first protrusion structure 2034. When there are multiple first protrusion structures 2034, a second mating groove 2037 is also provided between two adjacent first protrusion structures 2034, and a second protrusion structure 2035 that can cooperate with the second mating groove 2037 is provided on the corresponding splicing base. In a three-dimensional state, the first splicing base 2031 and the second splicing base 2032 are tightly spliced ​​into a planar whole through the mutual cooperation of the corresponding mating grooves and protrusion structures, providing vertical support and closed protection for the interlayer components.

[0059] The adapter plate 2033 is disposed at the connection between the first splicing base 2031 and the second splicing base 2032. It has a first through slot 2038 and a second through slot 2039 for the first protruding structure 2034 and the second protruding structure 2035 to pass through. In order to enhance the assembly firmness, the length of the first through slot 2038 can be slightly smaller than the length of the first protruding structure 2034, and an oblique extension groove 2040 is opened at one end to guide the protruding structure to slide in. The two ends of the second through slot 2039 can be opened with larger diameter movable holes 2041 to facilitate the insertion of the second protruding structure 2035. Furthermore, the first protruding structure 2034 is provided with a first locking groove, and the second protruding structure 2035 is provided with second locking grooves on both sides, for accommodating the adapter plate 2033 and limiting and locking the adapter plate 2033 after splicing to prevent it from loosening. The ends of the first splicing base 2031 and the second splicing base 2032 away from the adapter plate 2033 are connected to the corresponding side of the second folding cardboard 202. In the flat state, the adapter plate 2033 is attached to the surfaces of the two splicing bases; in the three-dimensional state, the adapter plate 2033 is perpendicular to the two splicing bases.

[0060] The first splicing structure set on both sides of the interlayer component provides external closed protection for the interlayer component in three-dimensional state. Combined with the planar support provided by the interlayer support plate, it ensures the accuracy of the three-dimensional shape and is not easily deformed. At the same time, it provides a hollow interlayer structure that can be filled for the interlayer component, which is far superior to the existing solution that relies on a single support component.

[0061] One side of the second card slot may also be provided with a plug buckle, and the other side is provided with a plug slot that matches the plug buckle, so as to extend the length of the second card slot. When needed, the length of the second card slot can be extended by staggering the plug buckle and the plug slot, so as to facilitate the splicing or disassembly of the adapter plate 2033.

[0062] In some specific embodiments, the origami outer body 300 includes a first outer panel 301 and a second outer panel 302. The ends of the first connecting plate 101 and the third connecting plate 103 away from the support plate 105 are connected to the first outer panel 301, and the ends of the second connecting plate 102 and the fourth connecting plate 104 away from the support plate 105 are connected to the second outer panel 302. The outer body not only beautifies the appearance of the model, but also serves as a support leg to support the model's standing in a three-dimensional state.

[0063] On the other hand, in order to enhance the overall stability of the model in three-dimensional state, the overall length of the upper connecting plate can be slightly smaller than that of the lower connecting plate, so that the upper connecting plate, the lower connecting plate and the origami outer body 300 can form a trapezoidal structure with a larger bottom and a smaller top, providing more stable support for the model as a whole.

[0064] Both substrates are provided with splicing parts on the side away from the adapter plate and on the side of both connecting plates away from the support plate for connecting with corresponding components. The splicing parts are corresponding insertion slots or connectors, which will not be described in detail here, and will not affect the operator's splicing operation.

[0065] In some specific embodiments, an electronic component 400 may be provided within the hollow layer and / or the structure between the hollow layers, including an LED light panel, a voice broadcast element, and a control element that can control the LED light panel and the voice broadcast element. The control element may integrate a touch switch or a photosensitive sensor. When the model is unfolded into a three-dimensional state, the LED light panel is triggered to turn on the lighting or flash, and the voice broadcast element is activated to play preset content, such as an introduction to the prototype location or related structure of the model, or playing corresponding holiday greetings when it is given as a gift, which greatly enhances the interactivity and fun of the model.

[0066] By creating a hollow layer between the origami connector and the origami body, an ideal installation space is provided for the integrated LED light panel, voice broadcasting elements, and other electronic components 400. This expands the functionality and interactivity of the model, enabling it to have audio-visual interactive effects and enhancing the product's added value and market competitiveness.

[0067] During operation, when the user unfolds the origami outer body 300, the upper and lower connecting plates rotate simultaneously, causing the entire origami connector 100 to rotate around the support plate 105. This action stretches the origami body 200, and the components between layers gradually unfold under the support of the corresponding connecting components and the first splicing structure 203, ultimately forming a stable three-dimensional structure. At the same time, the internal electronic components 400 are triggered, realizing sound and light interaction. Reversing the operation compresses the model back into a flat state for easy storage.
