Description

Technical Field

[0001] This application relates to the field of stereoscopic model technology, and in particular to a leg structure, a foldable module, and a foldable model. Background Technology

[0002] Animal models are of great value for conveying emotions and popularizing science. Not only can pet owners customize animal models to commemorate their beloved pets, but educators can also use animal models to explain things when conducting animal science education, so that students can quickly understand the animal's body structure.

[0003] However, existing three-dimensional animal models only imitate geometric outlines and oversimplify the musculoskeletal structure of animals, resulting in a large difference from the real appearance of animals and making it difficult to resonate with users. Summary of the Invention

[0004] In view of this, and in response to the above-mentioned technical problems, this application provides a leg structure, a foldable module, and a foldable model.

[0005] A first aspect of this application provides a leg structure including a first leg cylinder, a second leg cylinder, and a first support assembly. The second leg cylinder is connected to the first leg cylinder and is rotatable relative to the first leg cylinder. The first support assembly is at least partially located within the first and second leg cylinders, with one end connected to the first leg cylinder and the other end connected to the second leg cylinder. When an external force is applied to the second leg cylinder, causing it to rotate relative to the first leg cylinder, the first support assembly deforms to abut against the inner wall of the first leg cylinder, resulting in a three-dimensional cylindrical structure for the first leg cylinder.

[0006] In this application, the leg structure includes a first leg cylinder and a second leg cylinder that can rotate relative to each other, and the interior of each cylinder is provided with a first support component. In this way, the leg structure can not only change the bending shape of the leg, but also switch between a three-dimensional or folded state of the leg, making the leg structure more closely resemble the real form of an animal in reality, making the foldable model more realistic, and increasing the degree of fit between the foldable model and the body shape of a real animal. Therefore, for pet owners, the foldable model has a stronger commemorative significance and higher emotional value. For popular science education, the learners can more realistically understand the real body structure of animals, making the educational significance stronger and the teaching efficiency higher.

[0007] A second aspect of this application provides a foldable module, which includes a torso structure and a leg structure as mentioned in the first aspect of this application. The torso structure includes a torso cylinder and a leg connecting assembly. The leg connecting assembly is connected to the torso cylinder, and a first leg cylinder is connected to the leg connecting assembly. The leg connecting assembly is used to drive the leg structure to move relative to the torso cylinder to adjust the tilt angle of the leg structure relative to the torso structure.

[0008] A third aspect of this application provides a foldable model that includes a foldable module as mentioned in the second aspect of this application.

[0009] Since the beneficial effects of the second and third aspects of the embodiments of this application are derived from the first aspect of the embodiments of this application, the main beneficial effects of the second and third aspects of the embodiments of this application can be specifically referred to the beneficial effects of the first aspect of the embodiments of this application, and will not be repeated here.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0016] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains. The terms “an,” “a,” or “the,” as used herein, do not indicate a limitation of quantity, but are merely used to indicate the presence of at least one. Terms such as “comprising” or “including” mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as “connected” or “linked” are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0017] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] Animal models hold immense value for emotional expression and science education. Pet owners can customize models to commemorate their beloved pets, and educators can use models to explain animal anatomy, enabling learners to quickly understand the animal's structure. However, existing 3D animal models suffer from poor smoothness when switching between 3D and collapsible structures. Users often need multiple attempts to successfully switch from 3D to collapsible, severely impacting the user experience. Therefore, enabling users to seamlessly switch between the structural states of animal models is a pressing issue that needs to be addressed.

[0019] To address the above problems, this application provides a method such as Figures 1 to 3The foldable model shown includes a foldable module. This foldable module optimizes its mechanism to allow users to easily switch its shape according to their needs. In daily use, users can adjust the foldable module to a three-dimensional shape for display. When users move or need to fold up the foldable model due to factors such as care, they can adjust the foldable module from a three-dimensional shape to a flat shape to reduce the space occupied by the foldable model and facilitate its storage.

[0020] It should be noted that the foldable model can be a canine model, a feline model, a rodent model, etc., and the specific structural proportions of the model can be adjusted accordingly based on the actual animal structural proportions.

[0021] To better understand the technical content of this solution, the following will be combined with the embodiments of this application. Figures 1 to 41 This document provides a clear and complete description of the various technical solutions in some embodiments of the foldable module of this application, wherein the directions appearing in each figure are mutually corresponding and identified. It should be noted that, in order to clearly and obviously show the various features to the reader in the figures, when multiple substantially identical structures appear in some figures, only one structure is schematically labeled in the figures to avoid interfering with the user's clear identification.

[0022] Please refer to Figures 1 to 4 In the foldable module 1001 of this application, the torso cylinder 10 includes a torso cylinder wall 100. The torso cylinder wall 100 is provided with a first fold line 1005 and a second fold line 1006 arranged opposite to each other. The first fold line 1005, the second fold line 1006 and the central axis of the torso cylinder 10 are collinear to form a reference plane 1007. The torso cylinder wall 100 can be folded along the first fold line 1005 and the second fold line 1006 so that the torso cylinder 10 can switch back and forth between a three-dimensional state and a stacked state.

[0023] The torso offset structure 2 is located within the torso cylinder 10 and is connected to the inner wall of the torso cylinder 10. Please refer to the reference. Figures 6 to 9 The torso offset structure 2 is provided with a third fold line 210. The third fold line 210, the first fold line 1005, the second fold line 1006 and the central axis of the torso cylinder 10 are parallel to each other. The torso offset structure 2 can be folded along the third fold line 210.

[0024] When the external force is along a direction parallel to the reference plane 1007 (see reference) Figure 4When the first direction F1 is applied to the torso cylindrical wall 100, the first fold line 1005 and the second fold line 1006 approach each other, the torso cylindrical wall 100 bends along the first fold line 1005 and the second fold line 1006, and drives the torso offset structure 2 to bend along the third fold line 210 and abut against the torso cylindrical wall 100; when the external force is along the normal direction of the reference plane 1007 (refer to...), Figure 4 When the second direction F2 is applied to the torso cylindrical wall 100, the first fold line 1005 and the second fold line 1006 move away from each other, the torso cylindrical wall 100 unfolds along the first fold line 1005 and the second fold line 1006, and drives the torso offset structure 2 to unfold along the third fold line 210.

[0025] In the above embodiments, whenever an external force is applied to the torso cylinder wall 100, the external force will be at least partially perpendicular to or parallel to the reference plane 1007. Since the torso offset structure 2 is connected to the torso cylinder 10, the torso offset structure 2 can deform accordingly under the influence of the external force to provide support for the torso cylinder wall 100, or to remove the support for the torso cylinder wall 100 so that the torso cylinder 10 can be folded into a planar structure. In this way, the user can smoothly switch between the three-dimensional or stacked state of the foldable module 1001 in this application by pinching and pressing different parts of the torso cylinder 10, thereby improving the smoothness of use of the foldable module 1001 and the response speed of structural switching, thus improving the user's experience of using the foldable model 1000.

[0026] It should be noted that the foldable module 1001 in the stacked state may bulge slightly due to the material properties itself, but since the space occupied by the foldable module 1001 is significantly reduced, this state can still be considered as the foldable module 1001 being in the stacked state.

[0027] Please continue to refer to this. Figures 6 to 9 In some embodiments, the torso biasing structure 2 further includes a torso locking part 20 and a torso support part 21, both of which are connected to the torso cylindrical wall 100. The torso support part 21 is provided with the third fold line 210. When an external force is applied to the torso cylindrical wall 100 in a direction parallel to the reference plane 1007, the torso support part 21 bends along the third fold line 210, and the torso cylindrical wall 100 can drive the torso locking part 20 to move to a locked state, so that the torso support part 21 abuts against the torso cylindrical wall 100. When an external force is applied to the torso cylindrical wall 100 in a direction normal to the reference plane 1007, the torso support part 21 unfolds along the third fold line 210, and the torso cylindrical wall 100 drives the torso locking part 20 to move to an unlocked state.

[0028] In this embodiment, the torso locking part 20 is used to lock the structural state of the torso biasing structure 2, and the torso support part 21 is used to support the torso cylinder 10. The torso locking part 20 and the torso support part 21 cooperate with each other to adjust the structural state of the torso biasing structure 2 accordingly, so that the torso biasing structure 2 can adaptively support the torso cylinder 10.

[0029] It should be noted that the locking and unlocking states of the torso locking part 20 correspond to whether the foldable module 1001 can maintain a three-dimensional or folded state in this structural state. If the foldable module 1001 can maintain a three-dimensional state in this structural state, then the torso locking part 20 is in the locked state. If the foldable module 1001 cannot maintain a three-dimensional state in this structural state, that is, if the foldable module 1001 can freely switch between a three-dimensional and folded state, then the torso locking part 20 is in the unlocked state.

[0030] Further reference is available. Figure 7 In some embodiments, the torso locking portion 20 includes a first movable sub-portion 200, a second movable sub-portion 201, and a limiting portion 202. The first movable sub-portion 200 and the second movable sub-portion 201 are arranged facing each other so that the first movable sub-portion 200 and the second movable sub-portion 201 can move closer or further apart relative to each other. Both the first movable sub-portion 200 and the second movable sub-portion 201 are connected to the torso cylindrical wall 100, and the limiting portion 202 connects the first movable sub-portion 200 and the second movable sub-portion 201 to constrain the structural state of the first movable sub-portion 200 and the second movable sub-portion 201.

[0031] The limiting part 202 deforms to allow the torso locking part 20 to switch back and forth between the locked state and the unlocked state. When the torso locking part 20 is in the locked state, the limiting part 202 constrains the first movable sub-part 200 to abut against the second movable sub-part 201. When the torso locking part 20 is in the unlocked state, the first movable sub-part 200 moves away from the second movable sub-part 201. Thus, through the constraint of the limiting part 202, the torso locking part 20 can only switch states when a certain external force intervenes. Specifically, whether the torso locking part 20 switches from the locked state to the unlocked state or from the unlocked state to the locked state, if the torso locking part 20 is not subjected to a certain external force, it will not switch its current state arbitrarily. In this way, when the foldable model 1000 is blown by the wind or lightly touches other objects, it can change its own predetermined structural shape, thereby enabling the foldable model to generate structural deformation in sync with the user's own needs.

[0032] It should be noted that the limiting part 202 can be a cylindrical structure, and its deformation is due to the change in the radial dimension of its own cylinder after being subjected to force. Alternatively, the limiting part 202 can be an elastic element (such as a rubber band), and its deformation is due to the change in its own dimension after being subjected to force.

[0033] You can continue to refer to this. Figures 7 to 9 In some embodiments, the first movable sub-part 200 includes a first movable member 2000 and a first connecting member 2001. The first connecting member 2001 connects the first movable member 2000 and the limiting part 202 to opposite sides, respectively. The limiting part 202 is used to constrain the movable state of the first movable member 2000.

[0034] The second movable sub-part 201 includes a second movable member 2010 and a second connecting member 2011. The two opposite sides of the second connecting member 2011 are respectively connected to the second movable member 2010 and the limiting part 202. The limiting part 202 is used to constrain the movable state of the second movable member 2010.

[0035] When the torso locking part 20 is in the locked state, the first connecting member 2001 applies force to the first movable member 2000 along the first lever arm direction, and the second connecting member 2011 applies force to the second movable member 2010 along the second lever arm direction. On the side where the first connecting member 2001 and the second connecting member 2011 are located, the first lever arm direction and the second lever arm direction intersect, so that the first connecting member 2001 and the second connecting member 2011 are at an angle. The limiting part 202 constrains the first connecting member 2001 and the second connecting member 2011 so that the first connecting member 2001 and the second connecting member 2011 maintain the included angle state. Thus, under the connection action of the first connecting member 2001 and the second connecting member 2011, the first movable member 2000 abuts against the second movable member 2010. If no external force is applied, the limiting part can constrain the movement of the first connecting member 2001 and the second connecting member 2011 through its own elasticity, so that the first movable member 2000 remains abutting against the second movable member 2010.

[0036] It should be noted that the lever arm direction mentioned in the above embodiments can be referenced to the tilt position of each connector relative to each movable part in the accompanying drawings. Since the connector in the figure is a uniform plate structure, the lever arm direction is the extension direction of the connector. If the connector is a non-uniform structure, the lever arm direction can be parallel to the extension direction of the line connecting the centers of the two connecting ends of the connector.

[0037] Please continue to refer to this. Figures 7 to 9In some embodiments, the first connector 2001 includes a first connecting wall 2002, with the limiting part 202 and the first movable part respectively connected to opposite sides of the first connecting wall 2002. The first movable part is used to move the first connecting wall 2002. When the torso locking part 20 is in the locked state, the first connecting wall 2002 is parallel to the direction of the first lever arm. The second connector 2011 includes a second connecting wall 2012, with the limiting part 202 and the second movable part respectively connected to opposite sides of the second connecting wall 2012. The second movable part is used to move the second connecting wall 2012. When the torso locking part 20 is in the locked state, the second connecting wall 2012 is parallel to the direction of the second lever arm.

[0038] Please continue to refer to this. Figures 7 to 9 In some embodiments, the first connector 2001 includes a plurality of parallel and spaced first connecting walls 2002, which can strengthen the connection between the first movable member 2000 and the limiting part 202 through the plurality of first connecting walls 2002. Furthermore, the plurality of first connecting walls 2002 can be supported at multiple positions between the first movable member 2000 and the limiting part 202, so that the first movable member 2000 and the limiting part 202 can maintain the stability of their own structure during the movement and deformation of the first movable part 200.

[0039] Please continue to refer to this. Figures 7 to 9 In some embodiments, the second connector 2011 includes a plurality of parallel and spaced second connecting walls 2012, which can strengthen the connection between the second movable member 2010 and the limiting part 202 through the plurality of second connecting walls 2012. Furthermore, the plurality of second connecting walls 2012 can be supported at multiple positions between the second movable member 2010 and the limiting part 202, so that the second movable member 2010 and the limiting part 202 can maintain the stability of their own structure during the movement and deformation of the second movable part 201.

[0040] Please continue to refer to this. Figures 7 to 9 In some embodiments, the first connector 2001 is provided with a fourth fold line 2003, which is parallel to the third fold line 210. The first connector 2001 also includes a third connecting wall 2006, which connects the limiting part 202 and the first connecting wall 2002, and the third connecting wall 2006 is bendable relative to the first connecting wall 2002 along the fourth fold line 2003. The third connecting wall 2006 can improve the connection strength between the first connecting wall 2002 and the limiting part 202, thereby improving the structural stability of the first connector 2001.

[0041] Please continue to refer to this. Figures 7 to 9 In some embodiments, the first connector 2001 is provided with a fifth fold line 2004, which is parallel to the third fold line 210. The first connector 2001 also includes a fourth connecting wall 2005, which connects the first movable member 2000 and the first connecting wall 2002, and the third connecting wall 2006 is bendable relative to the first connecting wall 2002 along the fifth fold line 2004. The fourth connecting wall 2005 enhances the connection strength between the first connecting wall 2002 and the first movable member 2000, thereby improving the structural stability of the first connector 2001.

[0042] Please continue to refer to this. Figures 7 to 9 In some embodiments, the second connector 2011 is provided with a sixth fold line 2013, which is parallel to the third fold line 210. The second connector 2011 also includes a fifth connecting wall 2014, which connects the limiting portion 202 and the second connecting wall 2012, and the fifth connecting wall 2014 is bendable relative to the second connecting wall 2012 along the sixth fold line 2013. The fifth connecting wall 2014 can improve the connection strength between the second connecting wall 2012 and the limiting portion 202, thereby improving the structural stability of the second connector 2011.

[0043] Please continue to refer to this. Figures 7 to 11 In some embodiments, the second connector 2011 is provided with a seventh fold line 2015, which is parallel to the third fold line 210. The second connector 2011 also includes a sixth connecting wall 2016, which connects the second movable member 2010 and the second connecting wall 2012, and the sixth connecting wall 2016 is bendable relative to the second connecting wall 2012 along the seventh fold line 2015. The sixth connecting wall 2016 can improve the connection strength between the second connecting wall 2012 and the second movable member 2010, thereby improving the structural stability of the second connector 2011.

[0044] Please continue to refer to this. Figures 6 to 11 In some embodiments, the torso locking portion 20 includes a first movable sub-portion 200 and a limiting portion 202. The first movable sub-portion 200 is connected to the torso cylindrical wall 100, and the limiting portion 202 is connected to the first movable sub-portion 200. The limiting portion 202 deforms to allow the torso locking portion 20 to reciprocate between the locked state and the unlocked state. When the torso locking portion 20 is in the locked state, the first connecting member 2001 applies force to the first movable member 2000 along the direction of the first lever arm, and the limiting portion 202 abuts against and frictionally locks itself to the torso cylindrical wall 100.

[0045] Unlike the previous embodiments, in the above embodiments, the static friction between the limiting part 202 and the torso cylinder wall 100, and the elastic constraint of the limiting part 202 transmitted to the first movable part 200 through the first movable part 200, together stop the first movable part 200 in the immediate position, so that the torso locking part 20 no longer moves and the torso biasing structure 2 remains in a locked state.

[0046] For reference Figure 7 In some embodiments, the first movable sub-part 200 has a symmetrical structure, and the limiting part 202 has a cylindrical structure. The limiting part 202 is arranged around the outer periphery of the first connecting member 2001 and the first movable member 2000. Along the normal direction of the reference plane 1007, multiple first connecting members 2001 are symmetrically distributed on opposite sides of the first movable member 2000. Thus, along the normal direction of the reference plane 1007, multiple lever arms are formed between the limiting part 202 and the first movable member 2000 to facilitate the smooth movement of the first movable member 2000. In addition, multiple first connecting members 2001 can support the first movable member 2000 and the limiting member on multiple sides along the normal direction of the reference plane 1007, which helps maintain the structural stability of the first movable member 2000 and the limiting member, thereby improving the structural stability of the first movable sub-part 200.

[0047] For reference Figure 7 In some embodiments, the second movable sub-part 201 has a symmetrical structure, and the limiting part 202 has a cylindrical structure. The limiting part 202 is arranged around the outer periphery of the second connecting member 2011 and the second movable member 2010. Along the normal direction of the reference plane 1007, multiple second connecting members 2011 are symmetrically distributed on opposite sides of the second movable member 2010. Thus, along the normal direction of the reference plane 1007, multiple lever arms are formed between the limiting part 202 and the second movable member 2010 to facilitate the smooth movement of the second movable member 2010. In addition, multiple second connecting members 2011 can support the second movable member 2010 and the limiting member on multiple sides along the normal direction of the reference plane 1007, which helps maintain the structural stability of the second movable member 2010 and the limiting member, thereby improving the structural stability of the second movable sub-part 201.

[0048] You can continue to refer to this. Figures 7 to 11In some embodiments, the torso support portion 21 includes a first support sub-portion 211 and a second support sub-portion 212. Along the normal of the reference plane 1007, the first support sub-portion 211 and the second support sub-portion 212 are symmetrically distributed on opposite sides of the reference plane 1007 to symmetrically support the torso cylinder 10. Both the first support sub-portion 211 and the second support sub-portion 212 are provided with the third fold line 210. Both the first support sub-portion 211 and the second support sub-portion 212 can be folded along the third fold line 210 to abut against the torso cylinder wall 100. Thus, the first support sub-portion 211 and the second support sub-portion 212 can deform accordingly with the relative displacement of the first movable sub-portion 200 and the second movable sub-portion 201 to switch the structural state of the torso offset structure 2, thereby correspondingly adjusting the structural state of the foldable module 1001.

[0049] You can continue to refer to this. Figure 7 In some embodiments, the first support sub-part 211 further includes a plurality of first support walls 2110 and abutment walls 2111. The opposite sides of the first support walls 2110 are respectively connected to the torso cylindrical wall 100 and the support wall. Along the parallel direction of the reference plane 1007, each opposite side of the abutment wall 2111 is connected to one of the first support walls 2110. The abutment walls 2111 are used to connect the torso cylindrical body 10, so that the torso cylindrical body 10 can be supported in a three-dimensional state. The first support sub-part 211 has two third fold lines 210. The first support walls 2110 can be bent relative to the abutment walls 2111 along the third fold lines 210. When the torso locking part 20 is in the locked state, the first support walls 2110 bend relative to the abutment walls 2111, and the abutment walls 2111 abut against the torso cylindrical wall 100.

[0050] In some embodiments, the torso biasing structure 2 further includes a reinforcing support arm 203, one side of which is connected to the limiting part 202 and the other side is connected to the support part 71. In the locked state of the torso locking part 20, the reinforcing support arm 203 is inclined to the support part 71 and the limiting part 202. The reinforcing support arm 203 is used to transmit the external force transmitted to the limiting part 202 to the support part 71 so that the torso support part 21 can support the torso cylinder 10.

[0051] For reference Figure 12In some embodiments, the torso biasing structure 2 includes multiple parallel torso locking portions 20. Each torso locking portion 20 includes a first movable sub-part 200, a second movable sub-part 201, and a limiting portion 202. The first movable sub-part 200 and the second movable sub-part 201 are arranged facing each other, and both are connected to the inner wall of the torso cylinder 10. The first movable sub-part 200 and the second movable sub-part 201 can move relatively closer or further apart to drive the torso cylinder wall 100 to unfold or fold along the first fold line 1005 and the second fold line 1006, thereby increasing the connection area between the torso biasing structure 2 and the torso cylinder 10, and thus improving the linkage effect between the torso biasing structure 2 and the torso cylinder 10. The first movable sub-parts 200 of the multiple torso locking portions 20 can be connected sequentially, and the second movable sub-parts 201 of the multiple torso locking portions 20 can be connected sequentially, so that the torso biasing structure 2 is an integral structure.

[0052] For reference Figure 13 and Figure 14 In some embodiments, the inner wall of the torso cylinder 10 is connected to multiple torso offset structures 2 stacked along the parallel direction of the reference plane 1007. The limiting portions 202 of the multiple torso offset structures 2 are sequentially connected along the parallel direction of the reference plane 1007. The torso locking portion 20 includes a first movable sub-part 200, a second movable sub-part 201, and a limiting portion 202. The first movable sub-part 200 and the second movable sub-part 201 are arranged facing each other, and both the first movable sub-part 200 and the second movable sub-part 201 are connected to the inner wall of the torso cylinder 10. The first movable sub-part 200 and the second movable sub-part 201 can move relatively closer or further away to drive the torso cylinder wall 100 to unfold or fold along the first fold line 1005 and the second fold line 1006, thereby increasing the connection area between the torso offset structure 2 and the torso cylinder 10, and thus improving the linkage effect between the torso offset structure 2 and the torso cylinder 10.

[0053] in, Figure 12 and Figure 13 The specific structures of the torso locking part 20, limiting part 202 and / or torso support part 21 of the torso offset structure 2 shown can be referred to Figure 6 The specific structural features, operating principles, and beneficial effects of the embodiments shown will not be elaborated here.

[0054] Please refer to Figure 15 and Figure 16In some embodiments, the torso support 21 includes a plurality of first support sub-parts 211, each first support sub-part 211 having a third fold line 210, allowing it to be folded or unfolded along the third fold line 210. The first support sub-part 211 at the third fold line 210 is used to abut against the torso cylindrical wall 100. At least two first support sub-parts 211 are arranged opposite to each other, and a central bending line 213 is provided at the connection between the two first support sub-parts 211, so that the two first support sub-parts 211 can rotate relative to each other along the central bending line 213. In the locked state of the torso locking part 20, the structure of the two first support sub-parts 211 at the middle bending line 213 abuts against the surface of the limiting part 202. When an external force is applied to the torso cylinder wall 100 along the normal direction of the reference plane 1007, the structure of the two first support sub-parts 211 at the middle bending line 213 can abut against the limiting part 202 to compress the limiting part 202 and stabilize the torso locking part 20 in the locked state.

[0055] Please refer to Figure 17 and Figure 18 In some embodiments, the torso biasing structure 2 includes a limiting part 202 and a first movable sub-part 200. The limiting part 202 has a conical structure. A first connecting member 2001 is located in the limiting part 202 and is connected to the inner wall of the limiting part 202. The first movable member 2000 is connected to the inner wall of the torso cylinder 10. The conical end of the limiting part 202 is connected to the inner wall of the torso cylinder 10. The opening of the limiting part 202 faces the first movable sub-part 200. Thus, when the first movable member 2000 moves, the torso cylinder 10 can be unfolded or folded along the first fold line 1005 and the second fold line 1006.

[0056] In some embodiments, the first connector 2001 has a parallelogram structure.

[0057] Please refer to this as well. Figure 1 , Figure 19 , Figure 20 and Figure 21 In some embodiments, the foldable module 1001 further includes a chest and neck cylinder 3 and a chest and neck offset structure 4. The chest and neck cylinder 3 includes a chest and neck cylinder wall, which has an eighth fold line 300 and a ninth fold line 301 arranged opposite to each other. The eighth fold line 300 and the ninth fold line 301 are located on a first cross-section of the chest and neck cylinder wall, which is parallel to the normal of the reference plane 1007. The chest and neck cylinder wall can be folded along the eighth fold line 300 and the ninth fold line 301.

[0058] The chest and neck offset structure 4 is located within the chest and neck cylindrical body 3. The chest and neck offset structure 4 includes a tenth fold line 40, which is parallel to the first cross-section. The chest and neck offset structure 4 can be folded along the tenth fold line 40. The chest and neck offset structure 4 is connected to the torso offset structure 2 to drive the torso offset structure 2 to move within the torso cylindrical body 10.

[0059] When the external force is along a direction parallel to the first cross section (refer to...) Figures 1 to 3 When the external force (F3) is applied to the chest and neck cylindrical wall, the eighth fold line 300 and the ninth fold line 301 move towards each other, the torso cylindrical wall 100 bends along the eighth fold line 300 and the ninth fold line 301, and drives the chest and neck offset structure 4 to bend along the tenth fold line 40 and abut against the chest and neck cylindrical wall. When the external force is applied to the chest and neck cylindrical wall along the normal direction of the first section, the eighth fold line 300 and the ninth fold line 301 move away from each other, the chest and neck cylindrical wall unfolds along the eighth fold line 300 and the ninth fold line 301, and drives the chest and neck offset structure 4 to unfold along the tenth fold line 40.

[0060] In the above embodiments, whenever an external force is applied to the chest and neck cylinder 3, the external force will be at least partially perpendicular to or parallel to the first cross section. Therefore, since the torso offset structure 2 is connected to the chest and neck cylinder 3, the chest and neck offset structure 4 can be deformed accordingly by the external force to provide support for the chest and neck cylinder wall, or to remove the support for the chest and neck cylinder wall so that the chest and neck cylinder 3 can be folded into a planar structure. In this way, the user can smoothly switch between the three-dimensional or stacked state of the foldable module 1001 in this application by pinching and pressing different parts of the chest and neck cylinder 3, thereby improving the smoothness of use of the foldable module 1001 and the response speed of structural switching, thus improving the user's experience of using the foldable model 1000.

[0061] Please continue to refer to this. Figures 19 to 21 In some embodiments, the chest and neck offset structure 4 includes a chest and neck support portion 41 and a chest and neck linkage portion 42. The chest and neck support portion 41 supports the chest and neck cylinder 3. One side of the chest and neck support portion 41 is connected to the torso cylinder wall 100, and the other side of the chest and neck support portion 41 is connected to the chest and neck linkage portion 42. The chest and neck support portion 41 can bend and move relative to the chest and neck linkage portion 42 along the tenth fold line 40, and drive the torso cylinder 10 to bend and move relative to the chest and neck support portion 41 along the tenth fold line 40. In short, the chest and neck offset structure 4 can not only support the chest and neck cylinder 3, but also drive the torso cylinder 10 to move, so that the torso cylinder 10 can change with the structural changes of the chest and neck offset structure 4, thereby improving the linkage effect of the foldable module 1001.

[0062] Please continue to refer to this. Figures 19 to 21 In some embodiments, the chest and neck linkage 42 includes a first linkage 420 and a second linkage 421. The chest and neck linkage 42 also includes an eleventh fold line 43, which is parallel to the tenth fold line 40. The chest and neck support 41, the first linkage 420, and the second linkage 421 are sequentially connected, and the first linkage 420 is connected to the chest and neck cylinder wall. The chest and neck support 41 can be folded relative to the first linkage 420 along the tenth fold line 40, and the second linkage 421 can be folded relative to the first linkage 420 along the eleventh fold line 43 to adjust the support state of the chest and neck offset structure 4 for the chest and neck cylinder 3.

[0063] Along the normal of the reference plane 1007, the torso cylindrical wall 100 includes a first connection position (not shown) and a second connection position (not shown) that are arranged opposite to each other. The chest and neck support 41 is connected to the first connection position, and the second linkage 421 is connected to the second connection position, so as to drive the torso cylindrical wall 100 to fold or unfold.

[0064] Please continue to refer to this. Figures 19 to 21 In some embodiments, the first linkage 420 includes a first linkage sub-part 4200 and a second linkage sub-part 4201 connected sequentially. The first linkage sub-part 4200 is connected to the chest and neck cylinder wall. The chest and neck support 41 can be folded relative to the first linkage sub-part 4200 along the tenth fold line 40, and the second linkage sub-part 421 can be folded relative to the first linkage sub-part 4200 along the eleventh fold line 43. The second linkage sub-part 4201 extends at least partially out of the chest and neck cylinder 3, allowing the user to manually pull the second linkage sub-part 4201. When an external force is applied to the second linkage sub-part 4201 in a direction parallel to the first cross-section, the first linkage sub-part 4200 moves relative to the chest and neck cylinder wall, causing the chest and neck support 41 and the second linkage sub-part 421 to move the torso cylinder wall 100 relative to the chest and neck cylinder wall. The second linkage sub-part 4201 can be directly used by the user to directly control the structural form of the chest and neck offset structure 4, thereby adjusting the structural state of the chest and neck cylinder 3 accordingly.

[0065] In some embodiments, the first linkage sub-part 4200, the second linkage sub-part 4201, the second linkage part 421, and the chest and neck support part 41 have a parallelogram structure.

[0066] like Figure 19As shown, in some embodiments, the chest and neck offset structure 4 includes a chest and neck support portion 41 and a chest and neck linkage portion 42. The chest and neck support portion 41 is used to support the chest and neck cylinder 3. The two sides of the chest and neck support portion 41 are respectively connected to the torso cylinder wall 100 and the chest and neck linkage portion 42. The chest and neck linkage portion 42 is connected to the chest and neck cylinder 3 and can slide along the chest and neck cylinder 3. The chest and neck linkage portion 42 can drive the chest and neck support portion 41 to rotate relative to the chest and neck cylinder 3 along the tenth fold line 40.

[0067] like Figure 20 and Figure 21 As shown, in some embodiments, the chest and neck offset structure 4 includes a chest and neck support portion 41 and a chest and neck linkage portion 42. The chest and neck support portion 41 supports the chest and neck cylinder 3. The chest and neck support portion 41 has a twelfth fold line 44, which is parallel to the tenth fold line 40. The side of the chest and neck support portion 41 is connected to the torso cylinder wall 100, and the surface of the chest and neck support portion 41 is connected to the chest and neck linkage portion 42. The chest and neck linkage portion 42 can drive the chest and neck support portion 41 to fold along the twelfth fold line 44, and drive the torso cylinder 10 to bend and move relative to the chest and neck support portion 41 along the tenth fold line 40. The difference from the above embodiments is that the chest and neck support portion 41 in this embodiment can be bent itself.

[0068] In some embodiments, the chest and neck support portion 41 has a notch at the location of the twelfth fold line 44, and the chest and neck linkage portion 42 passes through the notch and abuts against the other side surface of the chest and neck support portion 41. The chest and neck linkage portion 42 may have an abutting protrusion.

[0069] In some embodiments, the neck and chest section 3 extends into the torso section 10. When the first section is perpendicular to the reference plane 1007, the neck and chest section wall and the torso section wall 100 are frictionally locked together so that the neck and torso of the foldable model 1000 can maintain relative stability.

[0070] In some embodiments, the inner wall of the chest and neck cylinder 3 is provided with a limiting sliding channel, through which the chest and neck linkage part 42 passes and can slide along the sliding channel. This enhances the connection strength between the chest and neck linkage part 42 and the chest and neck cylinder 3, ensuring that the connection between them remains intact. In some embodiments, two spaced and through notches are formed in the chest and neck cylinder wall to create the limiting sliding channel. In other embodiments, a limiting strip is provided on the inner surface of the chest and neck cylinder 3, and the limiting strip and the chest and neck cylinder wall together form the limiting sliding channel.

[0071] In some embodiments, in order to increase the synchronization between the neck offset structure and the torso offset structure 2, the chest and neck linkage part 42 in the chest and neck offset structure 4 is connected to the torso offset structure 2 or the torso cylinder 10. In this way, the user can make the chest and neck cylinder 3 and the torso cylinder 10 be supported or folded synchronously by applying force to the torso cylinder 10 or the chest and neck offset structure 4, thereby improving the efficiency and speed of the user's operation of the foldable model 1000.

[0072] For reference Figures 22 to 41 In some embodiments, the foldable module 1001 includes a leg structure 1002, such as Figure 22 and 26 As shown, the leg structure 1002 includes a first leg cylinder 5, a second leg cylinder 6, and a first support assembly 7. The second leg cylinder 6 is connected to the first leg cylinder 5 and is rotatable relative to the first leg cylinder 5. The first support assembly 7 is at least partially located within the first leg cylinder 5 and the second leg cylinder 6. One end of the first support assembly 7 is connected to the first leg cylinder 5, and the other end is connected to the second leg cylinder 6. When an external force is applied to the second leg cylinder 6, causing it to rotate relative to the first leg cylinder 5, the first support assembly 7 deforms to abut against the inner wall of the first leg cylinder 5, giving the first leg cylinder 5 a three-dimensional cylindrical structure.

[0073] It should be noted that, Figure 23 for Figure 22 Structural diagram of the main body (or, Figure 23 for Figure 22 (Internal main structure after removing external decorative panels) Figure 26 for Figure 25 Structural diagram of the main body (or, Figure 26 for Figure 25 (The internal main structure after removing the external decorative pieces) In some embodiments, decorative pieces can be added to the outside of the first leg cylinder 5 and / or the second leg cylinder 6 to make the appearance of the leg structure 1002 more closely match the actual appearance of the animal. The size of the decorative pieces can be changed according to the body structure of different parts of the animal to make the foldable model 1000 more realistic.

[0074] The leg structure 1002 in this application is provided with a first leg cylinder 5 and a second leg cylinder 6 that can rotate relative to each other, and a first support component 7 is provided inside the cylinder. In this way, the leg structure 1002 can not only change the bending shape of the leg, but also switch between three-dimensional and folded states of the leg, making the leg structure 1002 more in line with the real form of animals in reality, making the foldable model 1000 more realistic, and increasing the degree of fit between the foldable model 1000 and the body shape of real animals. Therefore, for pet owners, the foldable model 1000 brings stronger commemorative significance and higher emotional value. For popular science education, the learners can more realistically understand the real body structure of animals, making the educational significance stronger and the teaching efficiency higher.

[0075] Please refer to Figures 27 to 31 In some embodiments, the first support assembly 7 includes a linkage part 70 and a support part 71. The linkage part 70 is slidable relative to the inner wall of the first leg cylinder 5. One end of the linkage part 70 is connected to the inner wall of the first leg cylinder 5, and the other end of the linkage part 70 is connected to the second leg cylinder 6. One end of the support part 71 is fixedly connected to the inner wall of the first leg cylinder 5, and the other end of the support part 71 is connected to the linkage part 70. The support part 71 is used to abut against the inner wall of the first leg cylinder 5, so that the first leg cylinder 5 has a three-dimensional cylindrical structure. The first support assembly 7 is provided with a first crease 72. When the second leg cylinder 6 rotates relative to the first leg cylinder 5, the linkage part 70 moves relative to the inner wall of the first leg cylinder 5, and the support part 71 rotates relative to the linkage part 70 around the first crease 72 to adjust the relative position of the support part 71 and the inner wall of the first leg cylinder 5.

[0076] In the above embodiments, the first support component 7 can provide support and can be folded up to remove the support for the leg cylinder when the foldable model 1000 needs to be folded up, so that the leg cylinder can be folded up to reduce the space occupancy. The folding action of the leg cylinder can be done manually or by designing the connection relationship between the first support component 7 and the first leg cylinder 5 and / or the second leg cylinder 6 so that the first support component 7 can be linked to the first leg cylinder 5 and / or the second leg cylinder 6 to fold or unfold.

[0077] Please continue to refer to this. Figures 27 to 31In some embodiments, the linkage 70 includes a fourth linkage sub-part 700 and a fifth linkage sub-part 701 connected together. The end of the fourth linkage sub-part 700 away from the fifth linkage sub-part 701 is connected to the support part 71, and the end of the fifth linkage sub-part 701 away from the fourth linkage sub-part 700 is connected to the second leg cylinder 6. This allows the support part 71 to move relative to the second leg cylinder 6. The linkage 70 has a second crease 702 parallel to the first crease 72. When the second leg cylinder 6 rotates relative to the first leg cylinder 5, the fourth linkage sub-part 700 and the fifth linkage sub-part 701 move relative to the inner wall of the first leg cylinder 5. The fifth linkage sub-part 701 rotates relative to the fourth linkage sub-part 700 along the second crease 702, causing the support part 71 to rotate relative to the fourth linkage sub-part 700 along the first crease 72.

[0078] Please continue to refer to this. Figure 27 In some embodiments, the inner wall of the first leg cylinder 5 is provided with a first sliding channel 52. The support portion 71 and the fifth linkage sub-part 701 are respectively located on opposite sides of the first sliding channel 52. The fourth linkage sub-part 700 passes through the first sliding channel 52. When the fourth linkage sub-part 700 moves relative to the inner wall of the first leg cylinder 5, the fourth linkage sub-part 700 slides along the first sliding channel 52, thereby driving the support portion 71 and the fifth linkage sub-part 701 to move relative to the inner wall of the first leg cylinder 5. The first sliding channel 52 not only guides the movement path of the fourth linkage sub-part 700 so that the fourth linkage sub-part 700 does not move arbitrarily relative to the inner wall of the first leg cylinder, but also improves the connection strength between the fourth linkage sub-part 700 and the first leg cylinder 5.

[0079] In some embodiments, two spaced-apart and through notches are formed on the inner wall of the first leg cylinder 5 to form a first sliding channel 52. In other embodiments, a first baffle 54 is provided on the inner surface of the first leg cylinder 5, and the first baffle 54 and the inner wall of the first leg cylinder 5 together form the first sliding channel 52.

[0080] Please continue to refer to this. Figure 29 and Figure 30In some embodiments, the inner wall of the second leg cylinder 6 is provided with a second sliding channel 60. The linkage part 70 also includes a third linkage sub-part 703, which is connected to the opposite ends of the fifth linkage sub-part 701, respectively, along with the fourth linkage sub-part 700. The third linkage sub-part 703 passes through the second sliding channel 60. When the third linkage sub-part 703 moves relative to the inner wall of the second leg cylinder 6, it slides along the second sliding channel 60. The second sliding channel 60 not only guides the movement path of the third linkage sub-part 703, preventing it from moving arbitrarily relative to the inner wall of the second leg cylinder, but also enhances the connection strength between the third linkage sub-part 703 and the second leg cylinder 6.

[0081] In some embodiments, two spaced-apart and through notches are formed on the inner wall of the second leg cylinder 6 to form a second sliding channel 60. In other embodiments, a second baffle 61 is provided on the inner surface of the second leg cylinder 6, and the second baffle 61 and the inner wall of the second leg cylinder 6 together form the second sliding channel 60.

[0082] In some embodiments, the support portion 71 is provided with a fourth crease 73 and a third crease 74 parallel to the first crease 72, and the support portion 71 is rotatable relative to the inner wall of the first leg cylinder 5 along the fourth crease 73 and the third crease 74.

[0083] The support portion 71 further includes a third support sub-portion 75, a fourth support sub-portion 76, and a support linkage portion 77. The third support sub-portion 75 and the fourth support sub-portion 76 are spaced apart and connected parallel to the inner wall of the first leg cylinder 5, and the third support sub-portion 75 is connected to the linkage portion 70. The support linkage portion 77 is used to drive the third support sub-portion 75 to rotate along the fourth crease 73 relative to the inner wall of the first leg cylinder 5, and to drive the fourth support sub-portion 76 to rotate along the third crease 74 relative to the inner wall of the first leg cylinder 5. The support linkage portion 77 can increase the linkage effect between the third support sub-portion 75 and the fourth support sub-portion 76, and simplify the structure of the support portion 71. The same structure can achieve the effect of driving both the third support sub-portion 75 and the fourth support sub-portion 76 to move.

[0084] The opposite ends of the support linkage part 77 are respectively connected to the third support sub-part 75 and the fourth support sub-part 76, and the support linkage part 77 is parallel to the cylinder wall of the first leg cylinder 5. When the third support sub-part 75 rotates along the second crease 702 relative to the inner wall of the first leg cylinder 5, the support linkage part 77 drives the fourth support sub-part 76 to rotate along the third crease 74 relative to the inner wall of the first leg cylinder 5.

[0085] In the above embodiments, the support portion 71 is provided with multiple support sub-parts. In this way, the support portion 71 can act on more positions of the first leg cylinder 5 and provide support to multiple positions of the first leg cylinder 5. This improves the support effect of the support portion 71 on the first leg cylinder 5 and enhances the three-dimensional effect and structural stability of the first leg cylinder 5 in the three-dimensional state.

[0086] In some embodiments, the linkage 70 has a symmetrical structure, with the third linkage sub-part 703 and the fourth linkage sub-part 700 symmetrically distributed on opposite sides of the fifth linkage sub-part 701, so that the fifth linkage sub-part 701 can drive the third linkage sub-part 703 and the fourth linkage sub-part 700 to move at the same frequency, thereby improving the linkage effect and linkage speed of the linkage 70.

[0087] In some embodiments, the end of the third linkage sub-part 703 away from the fifth linkage sub-part 701 is connected to the support part 71, so as to drive the support part 71 to rotate relative to the inner wall of the second leg cylinder 6.

[0088] Please refer to this as well. Figure 24 , Figures 36 to 38 In some embodiments, the first leg cylinder 5 is further provided with a third sliding channel 53, which is spaced apart from the first sliding channel 52. The leg structure 1002 also includes a first connecting component 8, one side of which passes through the third sliding channel 53, and the other side of which is connected to the second leg cylinder 6. The first connecting component 8 can slide along the third sliding channel 53 to drive the second leg cylinder 6 to rotate relative to the first leg cylinder 5.

[0089] In the above embodiments, by setting a third sliding channel 53 spaced apart from the first sliding channel 52, the mutual interference between the first connecting component 8 and the linkage part 70 is reduced, allowing both to move smoothly relative to the inner wall of the first leg cylinder 5. The first connecting component 8 serves as the connecting medium between the first leg cylinder 5 and the second leg cylinder 6, enabling the first leg cylinder 5 and the second leg cylinder 6 to maintain a connection relationship when the first leg cylinder 5 rotates relative to the second leg cylinder 6.

[0090] Please refer to this as well. Figure 24 , Figures 36 to 38In some embodiments, the first connecting component 8 includes a first connecting sub-component 80 and a second connecting sub-component 81. One side of the first connecting sub-component 80 is fixedly connected to the second connecting sub-component 81, and the other side of the first connecting sub-component 80 passes through the third sliding channel 53. One side of the second connecting sub-component 81 is fixedly connected to the outer wall of the first leg cylinder 5, and the other side of the second connecting sub-component 81 is connected to the second leg cylinder 6. At the connection position of the first connecting sub-component 80 and the second connecting sub-component 81, the first connecting sub-component 80 and the first leg cylinder 5 are located on opposite sides of the second connecting sub-component 81.

[0091] In the above embodiment, the second connecting component connects the second leg cylinder 6 to the first leg cylinder 5, while the first connecting component 8 indirectly connects to the second leg cylinder 6 by connecting to the second connecting component. Thus, when the first leg cylinder 5 rotates relative to the second leg cylinder 6, the first connecting component 8 can move along the third sliding channel 53 to reduce structural interference caused by the relative rotation of the leg cylinders. Furthermore, the second connecting component 81 also helps the first connecting component 80 share a certain amount of connection strength; that is, the connection between the first leg cylinder 5 and the second leg cylinder 6 is jointly borne by the first connecting component 80 and the second connecting component 81, thereby ensuring a stable connection between the first leg cylinder 5 and the second leg cylinder 6.

[0092] In some embodiments, the second leg cylinder 6 has a fourth sliding channel in its cylinder wall, and the other side of the second connecting piece 81 passes through the second leg cylinder 6 so that it can slide along the fourth sliding channel. In this way, when the first leg cylinder 5 rotates relative to the second leg cylinder 6, both the first connecting piece 80 and the second connecting piece 81 can slide relative to the interior of their corresponding leg cylinders, so that the force on the first connecting assembly 8 as a whole can be symmetrically distributed, thereby extending the service life of the first connecting assembly 8.

[0093] Please refer to this as well. Figure 24 and Figure 38In some embodiments, the first connecting component 80 includes a first fixing portion 800 and a first connecting portion 801 connected together. The first connecting component 80 has a sixth fold 802, and the first fixing portion 800 is rotatable relative to the first connecting portion 801 along the sixth fold 802. The first fixing portion 800 is fixedly connected to the second leg cylinder 6, and the first connecting portion 801 passes through the third sliding channel 53. The second connecting component 81 includes a second fixing portion 810 and a second connecting portion 811 connected together. The second connecting component 81 has a fifth fold 812 parallel to the sixth fold 802. The second fixing portion 810 is rotatable relative to the second connecting portion 811 along the sixth fold 802. The second fixing portion 810 is fixedly connected to the first connecting portion 801, and the second connecting portion 811 is connected to the second leg cylinder 6.

[0094] Thus, not only do the first connecting sub-component 80 and the second connecting sub-component 81 provide corresponding connecting areas for connection, but the sliding connection between them is also ensured, allowing them to slide relative to the inner wall of their corresponding leg cylinders. Furthermore, the sixth crease 802 and the fifth crease 812 enhance the overlapping degree of the first connecting assembly 8, enabling it to overlap or unfold accordingly with the relative rotation between the leg cylinders. A schematic diagram of the unfolded structure of the first connecting assembly 8 can be used for reference. Figure 37 .

[0095] In some embodiments, in order to improve the misalignment effect between the third sliding channel 53 and the first sliding channel 52, a plate is added to the leg cylinder structure accordingly. Figures 31 to 33 As shown, a first mounting plate 55 is added to the inner wall of the first leg cylinder 5. The first mounting plate 55 is used to connect the first support component 7 and to form the first sliding channel 52. In this way, not only is the internal structural strength of the first leg cylinder 5 improved, but the first mounting plate 55 can also form a physical isolation barrier between the first sliding channel 52 and the third sliding channel 53, so that the first sliding channel 52 and the third sliding channel 53 are not connected.

[0096] Please refer back. Figure 34 In some embodiments, the size of the first leg cylinder 5 is larger than the size of the second leg cylinder 6, so that the leg structure 1002 more closely conforms to the actual shape of the animal. For example, a larger first leg cylinder 5 is used to simulate the animal's thigh, and a smaller second leg cylinder 6 is used to simulate the animal's lower leg. In addition, the first leg cylinder 5 and the second leg cylinder 6 can also be configured as irregular cylinders, such as trapezoidal cylinders.

[0097] Please refer back. Figures 22 to 26 In some embodiments, the leg structure 1002 further includes a third leg cylinder 9, wherein the first leg cylinder 5, the second leg cylinder 6, and the third leg cylinder 9 are sequentially connected. The leg structure 1002 also includes a third support assembly 90, which is at least partially located in the second leg cylinder 6 and the third leg cylinder 9. In the second leg cylinder 6, the first support assembly 7 and the third support assembly 90 are arranged opposite to each other so that the rotational directions of the different leg cylinders can be staggered. For example, the first leg cylinder 5 rotates clockwise relative to the second leg cylinder 6, and the third leg cylinder 9 rotates counterclockwise relative to the second leg cylinder 6.

[0098] In the above embodiments, the aim is to increase the similarity to the skeletal structure of an animal's leg by increasing the number of leg tubes, thereby making the foldable model 1000 more realistic in resemblance to the animal's true form.

[0099] Please refer to Figure 39 and Figure 40 In some embodiments, the foldable module 1001 includes a torso structure 1, which includes a torso cylinder 10 and a leg connecting assembly 11. The leg connecting assembly 11 is connected to the torso cylinder 10, and a first leg cylinder 5 is connected to the leg connecting assembly 11. The leg connecting assembly 11 is used to move the leg structure 1002 relative to the torso cylinder 10 to adjust the tilt angle of the leg structure 1002 relative to the torso structure 1. Thus, the leg structure 1002 can rotate relative to the torso cylinder 10 as the foldable model 1000 adjusts its posture, allowing the foldable model 1000 to adopt a posture that conforms to the actual body shape of an animal, increasing the mimicry effect of the foldable model 1000.

[0100] Please refer to Figure 39 and Figure 41 In some embodiments, the leg connection structure includes a leg connection part 110 and a rotation linkage part 111 connected together. The leg connection part 110 is used to connect the first leg cylinder 5, and the rotation linkage part 111 is connected to the torso cylinder 10 and can rotate relative to the torso cylinder 10. The rotation linkage part 111 includes a rotation connector 1110 and a rotation linkage part 1114, such as... Figure 41As shown, the rotating connector 1110 includes a fixing part 1111 and an adjusting part 1112. The fixing part 1111 and the adjusting part 1112 are connected end to end to make the rotating connector 1110 cylindrical. The fixing part 1111 is fixedly connected to the torso cylinder 10. The adjusting part 1112 has multiple adjusting creases 1113. The adjusting part 1112 can be folded along different adjusting creases 1113 to allow the adjusting part 1112 to rotate relative to the torso cylinder 10. The opposite sides of the rotating linkage 1114 connect the adjusting part 1112 and the first leg cylinder 5.

[0101] Among them, the rotating linkage 1114 increases the flexibility of the leg structure 1002 in rotating relative to the torso cylinder 10, and can stop at the position after the leg structure 1002 rotates relative to the torso cylinder 10, thereby improving the degree of restoration of the foldable model 1000 to the real form of the animal.

[0102] For reference Figure 39 and Figure 40 In some embodiments, the torso cylinder 10 is further provided with a sliding groove 101. The rotational linkage 1114 includes a first rotational linkage sub-part 1115 and a second rotational linkage sub-part 1116 connected to each other, with the first rotational linkage sub-part bent at the second rotational linkage sub-part 1116. The first rotational linkage sub-part is connected to the adjusting part 1112, and the second rotational linkage sub-part 1116 is slidably connected to the groove wall of the sliding groove 101. The sliding groove 101 can guide the rotational path of the rotational linkage 1114 and can stably connect the second rotational linkage sub-part 1116 to the torso cylinder 10, thereby increasing the connection strength and relative rotational effect between the rotational linkage 1110 and the torso cylinder 10.

[0103] For reference Figure 39 and Figure 40 In some embodiments, the leg connecting portion 110 further includes a reinforcing connector 1117, one side of which is fixedly connected to the torso cylinder 10, and the other side is fixedly connected to the rotation linkage 1114. The reinforcing connector 1117 is used to connect the first surface 50 of the first leg cylinder 5, and the rotation linkage 1114 is used to connect the second surface 51 of the first leg cylinder 5 adjacent to the first surface 50, so that the leg structure 1002 can achieve a three-dimensional state through the connection relationship with the leg connecting portion 110.

[0104] In some embodiments, when the torso cylinder 10 is in a stacked state, the reinforcing connector 1117 is attached to the surface of the torso cylinder 10. When the torso cylinder 10 is in a three-dimensional state, the reinforcing connector 1117 is suspended on the surface of the reference plane 1007 and the rotation linkage 1114. In this way, the leg cylinder can adjust its own three-dimensional state and stacked state accordingly through the linkage action of the reinforcing connector 1117.

[0105] In some embodiments, the torso structure 1 includes a torso cylinder 10 and a leg connecting assembly 11. The leg connecting assembly 11 is connected to the torso cylinder 10, and a first leg cylinder 5 is connected to the leg connecting assembly 11. The leg connecting assembly 11 is used to move the leg structure 1002 relative to the torso cylinder 10 to adjust the tilt angle of the leg structure 1002 relative to the torso structure 1. It should be noted that the first leg cylinder 5 represents the thigh portion of the actual animal leg structure 1002, thus the connection of the first leg cylinder 5 to the leg connecting assembly 11 more closely conforms to the animal's actual body structure.

[0106] In some embodiments, each structure may have a reinforcing layer attached to both sides of the crease to increase the strength and stability of the structure while ensuring its foldability.
