Description

Technical Field

[0001] This application relates to the field of toy manufacturing technology, and in particular to a rotatable combination structure for the eyes and neck of a figurine. Background Technology

[0002] Figurines are typically based on characters from anime, games, and movies, and are meticulously handcrafted. These characters often have distinct personalities and characteristics, and figurines perfectly recreate their images and details. With advancements in 3D printing and precision mold manufacturing technologies, the production process of figurines has continuously improved, resulting in even more refined details.

[0003] Traditional figurines often have fixed eye and neck structures, which limits the diversity of facial expressions and reduces their expressiveness when simulating real human movements. Utility Model Content

[0004] To solve or partially solve the problems existing in the related technologies, this application provides a rotatable combination structure for the eyes and neck of a figurine.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0006] A rotatable assembly structure for the eyes and neck of a figurine, comprising a face, eyes, neck, and back of the head, further comprising:

[0007] An oval through-hole is made in the face and the bottom of the back of the head, and the neck is inserted into the oval through-hole;

[0008] A groove is created on the back of the head and fits the eyes; the eyes rotate and connect to the groove.

[0009] The shape of the neck matches the elliptical through hole, and the major axis diameter of the neck is slightly smaller than the major axis dimension of the elliptical through hole and larger than the minor axis dimension of the elliptical through hole, so that the minor axis of the elliptical through hole restricts the range of rotation of the neck in the horizontal plane.

[0010] Optionally, the bottom wall of the groove is provided with a blocking protrusion, and the eye is provided with a limiting protrusion on the side near the bottom wall of the groove.

[0011] Optionally, the face is provided with an insertion hole that is adapted to the front end of the rear head.

[0012] Optionally, the lower end of the face is provided with a positioning hole with a semi-elliptical cross section, and the lower end of the back of the head is provided with a mating hole with a semi-elliptical cross section that matches the positioning hole.

[0013] Optionally, the positioning hole and the mating hole cooperate to form the elliptical through hole.

[0014] Optionally, the forward extension of the neck is configured with an elliptical shape that adapts to the elliptical through-hole.

[0015] Optionally, four limiting protrusions are provided.

[0016] The beneficial effects of this application are as follows: The eyes of this application can rotate, and the neck adopts an insert design. Combined with the oval through-holes at the bottom of the face and the back of the head, a stable locking mechanism is formed, ensuring the stability of the head while allowing the head to rotate in multiple degrees of freedom, increasing the range of motion of the figure. This design not only enhances the figure's aesthetic appeal but also strengthens its interactivity and fun, enabling the figure to better simulate the movements and expressions of real people, increasing the diversity of the figure's facial expressions, and thus improving its expressiveness in simulating the movements of real people.

[0033] The above description is merely an optional embodiment of this application and is not intended to limit this application.

[0034] To make the objectives, technical solutions, and beneficial effects of this application clearer, the preferred embodiments of this application will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding by those skilled in the art.

[0035] Example 1:

[0036] See Figures 1 to 4 A rotatable assembly structure for the eyes and neck of a figurine, comprising a face 1, eyes 2, neck 3, and back of the head 4, further comprising:

[0037] An elliptical through-hole is opened at the bottom of the face 1 and the back of the head 4, and the neck 3 is inserted into the elliptical through-hole;

[0038] A groove 5 is formed on the back of the head 4 and is adapted to the eye 2. The eye 2 is rotatably connected to the groove 5.

[0039] The shape of the neck 3 matches the elliptical through hole, and the major axis diameter of the neck 3 is slightly smaller than the major axis dimension of the elliptical through hole and larger than the minor axis dimension of the elliptical through hole, so that the minor axis of the elliptical through hole restricts the rotation range of the neck 3 on the horizontal plane.

[0040] Specifically, the groove 5 is used to install and support the eye part 2. The eye part 2 is rotatably connected to the groove 5, allowing it to rotate freely within the groove 5. This rotation enhances the expressive possibilities of the figure's facial features. The groove 5 has arc-shaped limiting blocks at its upper and lower ends that match the curvature of the eye part 2, ensuring the eye part 2 stays in place and doesn't fall out, thus improving its stability. The face 1 and the bottom of the head 4 have elliptical through holes that match the neck 3. The diameter of the neck 3 is slightly smaller than the major axis of the elliptical through hole but larger than its minor axis, allowing the neck 3 to be inserted vertically into the elliptical through hole. However, its rotation in the horizontal plane is somewhat restricted. When the neck 3 attempts to rotate along the minor axis of the elliptical through hole, it abuts against the edge of the hole, thus limiting its rotation. This design provides the neck 3 with some flexibility in the horizontal direction, but not complete free rotation. Simultaneously, it allows the head to rotate in multiple degrees of freedom without restricting the rotation of the eye part 2.

[0041] After the eyes 2 are inserted into the groove 5, the face 1 is placed over the front of the back head 4. At this time, the lower part of the face 1 and the lower part of the back head 4 form an elliptical through hole that fits the neck 3. The neck 3 is then inserted into the elliptical through hole, thus assembling the figure. The face 1 provides the basic appearance of the figure. The face 1 is manufactured using a high-precision 3D printing process. The face 1 is made according to the design drawings. This structure should accurately reproduce the facial features of the target character, including but not limited to facial features, contours, and expression details.

[0042] In summary, the eyes 2 of this application are rotatable, and the neck 3 adopts an insert design. Combined with the elliptical through-holes at the bottom of the face 1 and the rear head 4, a stable locking mechanism is formed, ensuring the stability of the head while allowing the head to rotate in multiple degrees of freedom, increasing the range of motion of the figure. This design not only enhances the figure's aesthetic appeal but also strengthens its interactivity and fun, enabling the figure to better simulate the movements and expressions of real people, increasing the diversity of the figure's facial expressions, and thus improving its expressiveness in simulating the movements of real people.

[0043] It should be noted that this application focuses on the rotatable combination structure of the figure's eyes and neck, while the face 1, eyes 2, neck 3 and back of the head 4 are common knowledge, and their specific structures will not be described in detail here.

[0044] Example 2:

[0045] See Figure 3 , Figure 5 and Figure 6 Based on Embodiment 1, optionally, the bottom wall of the groove 5 is provided with a blocking protrusion, and the eye 2 is provided with a limiting protrusion 6 on the side near the bottom wall of the groove 5.

[0046] Specifically, the end of the limiting protrusion 6 furthest from the eye 2 is slidably connected to the bottom wall of the groove 5. When the eye 2 rotates to a certain angle, the limiting protrusion 6 abuts against the blocking protrusion on the bottom wall of the groove 5, thus blocking the movement of the limiting protrusion 6 and restricting the rotation angle of the eye 2. By allowing the eye 2 to rotate within a limited range within the overall shape, changes in eye movements are achieved, enhancing the richness and realism of the figure's expression.

[0047] See Figure 4 Optionally, the face 1 is provided with an insertion hole 7 that is adapted to the front end of the rear head 4.

[0048] Specifically, by opening the embedding hole 7, it is convenient to assemble the front end of the rear head 4 with the face 1.

[0049] See Figure 7 Optionally, the lower end of the face 1 is provided with a positioning hole 8 with a semi-elliptical cross section, and the lower end of the head 4 is provided with a mating hole 9 with a semi-elliptical cross section that matches the positioning hole 8.

[0050] Optionally, the positioning hole 8 and the mating hole 9 are fitted together to form the elliptical through hole.

[0051] Optionally, the forward extension of the neck 3 is configured with an elliptical shape that matches the elliptical through hole.

[0052] Specifically, the semi-elliptical cross-sections of the positioning hole 8 and the mating hole 9 can be combined to form an ellipse. This design allows the neck 3 to be inserted vertically and has some flexibility in the horizontal direction, but it cannot rotate completely freely. The forward extension of the neck 3 is designed with a fitting elliptical shape to ensure a tight fit with the face 1 and the back of the head 4 after insertion. It also allows the head to rotate in multiple degrees of freedom without restricting the rotation of the eyes 2. These components are then assembled into a complete figure head structure. During assembly, the rotation range of the eyes 2 and the locking force of the neck 3 are precisely adjusted to ensure that the dynamic expression and structural stability of the figure head meet the design requirements.

[0053] In addition, the dimensions of the neck structure (especially the diameter or width of its insertion portion) need to match the major axis of the ellipse to ensure that the neck structure can be smoothly inserted into the elliptical hole. Simultaneously, the cross-sectional shape of the neck structure also needs to be adapted to the shape of the elliptical hole to reduce friction and resistance during assembly. A certain assembly clearance needs to be left between the neck structure and the elliptical hole to allow the neck structure a certain range of motion after insertion, while avoiding excessive tightness that could lead to wear or damage.

[0054] See Figure 3 Optionally, the limiting protrusion 6 is provided with four.

[0055] Specifically, by setting multiple limiting protrusions 6 in conjunction with multiple blocking protrusions, the rotation range of the figure's eyes 2 can be precisely controlled. This helps to achieve specific expressions or perspectives, making the figure more vivid and realistic. At the same time, limiting the rotation range of the eyes 2 can also prevent excessive rotation of the eyes 2 from damaging the connecting structure or affecting the overall aesthetics.

[0056] It should be noted that the structures and / or installation methods not detailed in this application are those that can be known by those skilled in the art in combination with common knowledge and / or prior art, and are not the focus of this application, and will not be elaborated further here.

[0057] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this application; the dimensions of the drawings are not related to the specific physical object, and the physical object dimensions can be arbitrarily changed.
