Description

Technical Field

[0001] The present invention relates to the field of toys, and more particularly to an internal bone support for a highly realistic toy. Background Art

[0002] In the toy manufacturing industry, the doll skeleton, as a key component determining the movement performance and overall texture of the doll, has always been the focus of research and production. With the continuous improvement of consumers' requirements for toy quality and authenticity, the design and manufacture of high-performance doll skeletons have become increasingly important. With the continuous development of the toy market, higher requirements are put forward for the performance and functions of doll skeletons. Not only does the skeleton need to have high precision and strength to ensure the smoothness and accuracy of the doll's movements, but also higher stability and economy in production and manufacturing. At the same time, different sizes and types of toy products are emerging continuously, such as humanoid dolls, plush toys, animal models, etc., which requires the design and manufacture of doll skeletons to be unrestricted by product size and meet diverse application requirements.

[0003] However, there are many deficiencies in the prior art in terms of the precision, strength, production stability, and manufacturing process quality of bone manufacturing. In small-sized products, the prior art often fails to solve the design and manufacturing problems of kinematic pairs restricted by size and structure, resulting in limited movement functions of the doll, making it difficult to achieve full-scale simulation movements and affecting the authenticity and interest of the toy. Therefore, the present invention proposes an internal bone support for a highly realistic toy. Summary of the Invention

[0004] The purpose of the present invention is to provide an internal bone support for a highly realistic toy to solve the problems in the prior art described in the above background art, namely, there are many deficiencies in the precision, strength, production stability, and manufacturing process quality of bone manufacturing. In small-sized products, the prior art often fails to solve the design and manufacturing problems of kinematic pairs restricted by size and structure, resulting in limited movement functions of the doll, making it difficult to achieve full-scale simulation movements and affecting the authenticity and interest of the toy.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A high-fidelity toy internal bone bracket, including an internal skeleton, the internal skeleton is composed of a neck rotating shaft, a chest ball connection fixing seat, a waist connecting shaft, an abdominal ball connection fixing seat, a leg mechanism and an arm mechanism. The bottom of the chest ball connection fixing seat is movably connected to the abdominal ball connection fixing seat through the waist connecting shaft. The side of the chest ball connection fixing seat is movably connected to the arm mechanism through a ball joint, and the top of the chest ball connection fixing seat is movably connected to the neck rotating shaft. Both ends of the neck rotating shaft and the waist connecting shaft are spherical structures. The side of the abdominal ball connection fixing seat is movably connected to the leg mechanism through a ball joint. The leg mechanism and the arm mechanism are both composed of a rotating shaft connection component and a hinge component, and the rotating shaft connection component and the hinge component are connected up and down.

[0007] Optionally, the chest ball connection fixing seat includes an upper piece of the chest ball fixing seat and a lower piece of the chest ball fixing seat. The upper piece of the chest ball fixing seat and the lower piece of the chest ball fixing seat are riveted by a plurality of rivets. The abdominal ball connection fixing seat includes an upper piece of the abdominal ball fixing seat and a lower piece of the abdominal ball fixing seat. The upper piece of the abdominal ball fixing seat and the lower piece of the abdominal ball fixing seat are riveted by a plurality of rivets to form the chest ball connection fixing seat.

[0008] Optionally, the rotating shaft connection component includes a first connecting rod, a second connecting rod and a steel pipe. The first connecting rod is movably connected to the ball joint through a rivet. The first connecting rod is connected to the second connecting rod. The body of the steel pipe is provided with a forming groove, and the first connecting rod and the second connecting rod are correspondingly provided with grooves at the same position as the steel pipe. The first connecting rod and the second connecting rod are locked by pressing the groove of the steel pipe.

[0009] Optionally, the first connecting rod and the second connecting rod can rotate 360 degrees, and the diameters of the first connecting rod and the second connecting rod are applicable to 2.0 - 3.0 millimeters.

[0010] Optionally, the hinge component includes a third connecting rod, a fourth connecting rod and a hinge rotating shaft. The third connecting rod is the same rod as the second connecting rod. The third connecting rod is movably connected to the fourth connecting rod through the hinge rotating shaft, and the hinge rotating shaft can be equivalent to a rivet.

[0011] Optionally, the second connecting rod and the third connecting rod can move within the range of 30 degrees - 180 degrees through the hinge rotating shaft.

[0012] Optionally, the entire internal skeleton is made of metal material.

[0013] Optionally, the length of the connecting rod on the leg mechanism is greater than the length of the connecting rod on the arm mechanism.

[0014] The beneficial effects of the present invention are:

[0015] 1. In the present invention, various components of the internal bone bracket of the high-fidelity toy are connected through ball connection structures, planar rotating shafts, and 360-degree rotating shaft connection structures, enabling the toy to make rotations in multiple angles and directions and assume arbitrary shapes, almost completely imitating all actions that a real person can perform, making toys such as dolls extremely realistic. The hinge components and 360-degree rotating shaft connection components designed in the present invention are not affected by the size of the doll, so that the imitation movements of the doll are not restricted.

[0016] 2. In the present invention, by adopting such a planar hinge component, the upper and lower connecting rods are respectively connected to the front and rear parts of the leg, and the rivet rotating shaft serves as the rotation center. The design of the front-end shaping dimensions enables the leg to stop rotating when standing (about 180 degrees) and when bending to a certain extent (about 30 degrees), simulating real leg movements. The connecting rod structure split in the middle is convenient for processing and production, while ensuring the firmness and movement accuracy of the leg joint. Moreover, this structure will not damage the soft rubber layer wrapped outside the connecting rod, making the toy look more beautiful and realistic.

[0017] 3. The structure of the present invention simplifies the development difficulty and quantity of the skeleton mold, improves the production efficiency through the application of simple special tooling equipment, and has flexible production capacity by using standardized design modules to design parts. The all-metal skeleton, due to reasonable structural design and assembly scheme, has precise finished product dimensions, extremely small errors, a simple and durable skeleton, smooth movement, and standardized actions, with high productivity and economic value.

[0032] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0033] The following will be described in conjunction with the preferred embodiments of the device of the present invention.

[0034] Embodiment 1:

[0035] As shown in the attached Figure 1 to the attached Figure 4 The present invention provides a high-fidelity toy internal bone bracket, including an internal skeleton, which is composed of a neck rotating shaft 1, a chest ball connection fixing seat 2, a waist connection shaft 3, an abdominal ball connection fixing seat 4, a leg mechanism 5 and an arm mechanism 6. The bottom of the chest ball connection fixing seat 2 is movably connected to the abdominal ball connection fixing seat 4 through the waist connection shaft 3. The side of the chest ball connection fixing seat 2 is movably connected to the arm mechanism 6 through a ball joint 9, and the top of the chest ball connection fixing seat 2 is movably connected to the neck rotating shaft 1. Both ends of the neck rotating shaft 1 and the waist connection shaft 3 are spherical structures. This unique spherical structure design draws on the concept of connecting the spherical ends of the movable joints to the body parts in the movable model, enabling the neck and waist to achieve flexible rotation at multiple angles, with a smooth rotation process and no sense of pause, greatly enhancing the realism of the toy's movements. The side of the abdominal ball connection fixing seat 4 is movably connected to the leg mechanism 5 through a ball joint 9. Both the leg mechanism 5 and the arm mechanism 6 are composed of a rotating shaft connection component 7 and a hinge component 8. The rotating shaft connection component 7 and the hinge component 8 are connected up and down, similar to the overall structure formed by connecting different body parts through movable joints in the movable model, which not only ensures the flexibility of the limb joints but also enhances the firmness of the structure.

[0036] Furthermore, the chest ball connection fixing seat 2 includes an upper piece 201 of the chest ball fixing seat and a lower piece 202 of the chest ball fixing seat. The upper piece 201 of the chest ball fixing seat and the lower piece 202 of the chest ball fixing seat are riveted together by a number of rivets. The abdominal ball connection fixing seat 4 includes an upper piece 401 of the abdominal ball fixing seat and a lower piece 402 of the abdominal ball fixing seat. The upper piece 401 of the abdominal ball fixing seat and the lower piece 402 of the abdominal ball fixing seat are riveted together by a number of rivets to form the chest ball connection fixing seat 2. This split design not only facilitates the manufacture of the mold and the assembly of the product, effectively reducing the development cost of the skeleton mold, but also can quickly adapt to the production requirements of different-sized toys by standardizing the design of modular parts, establishing a flexible production system, further reducing the production cost and improving the production efficiency. This is just like in a movable model, the body part is formed by riveting two stainless steel sheets to form a hollow spherical surface, which is connected to the movable joint to achieve flexible rotation and shaping. Our split design also provides guarantee for the flexibility and adaptability of the bone bracket. By simplifying the development difficulty and quantity of the skeleton mold, the production efficiency is improved by applying simple special tooling equipment, and the flexible production ability is possessed by adopting the standardized design of modular parts. The all-metal skeleton, due to its reasonable structural design and assembly scheme, has precise manufacturing, accurate finished product dimensions, extremely small errors, simple and durable structure, smooth movement, standard actions, and great productive and economic value.

[0037] Embodiment 2:

[0038] As shown in the Figure 3 to the Figure 4 accompanying drawings, this embodiment is basically the same as the previous embodiment. The difference is that the rotating shaft connection assembly 7 includes a first connecting rod 701, a second connecting rod 702 and a steel pipe 703. The first connecting rod 701 is movably connected to the ball joint 9 by a rivet. The first connecting rod 701 is connected to the second connecting rod 702. The body of the steel pipe 703 is provided with a forming groove, and the first connecting rod 701 and the second connecting rod 702 are correspondingly provided with grooves at the same position as the steel pipe 703. The first connecting rod 701 and the second connecting rod 702 are locked by pressing the groove of the steel pipe 703.

[0039] Furthermore, the first connecting rod 701 and the second connecting rod 702 can rotate 360 degrees, and the diameters of the first connecting rod 701 and the second connecting rod 702 are applicable to 2.0 - 3.0 mm.

[0040] Specifically, both the first link 701 and the second link 702 are turned with grooves, which are carefully designed with shapes and dimensions matching the formed grooves of the subsequent press-fitted steel pipe 703. The existence of the grooves provides positioning and fixing points for the tight connection between the steel pipe 703 and the links, enabling the steel pipe 703 to be accurately embedded into the links and forming a certain constraint relationship with the links, but not completely restricting the rotation of the links. When the steel pipe 703 is press-fitted with the upper and lower links, the formed grooves of the steel pipe 703 will cooperate with the grooves of the upper and lower links to form a relatively stable structure. This cooperation method not only ensures the connection strength between the links and the steel pipe 703 but also provides space for the rotation of the links. Although the upper and lower links are locked by the press-formed grooves of the steel pipe 703, there is a certain small gap between the links and the steel pipe 703. This gap will neither cause looseness or wobbling of the links during rotation nor prevent the links from having enough space for 360-degree rotation, providing an effective solution for the flexible rotation of the toy joints and enabling the toy to present more natural and realistic action effects.

[0041] Furthermore, the hinge assembly 8 includes a third link 801, a fourth link 802, and a hinge rotating shaft 803. The third link 801 is the same as the second link 702. The third link 801 is movably connected to the fourth link 802 through the hinge rotating shaft 803, and the hinge rotating shaft 803 can be equivalent to a rivet.

[0042] Furthermore, the second link 702 and the third link 801 can move within the range of 30 degrees - 180 degrees through the hinge rotating shaft 803. The front-end shaping dimensions in the hinge assembly 8 are designed to ensure that the two links can be folded within the range of approximately 30 degrees and 180 degrees. The structure with a break in the middle of the link is simple to process, firm, accurate in movement, and high in structural strength. And it tries to protect without damaging the rubber coating layer or various outer wrapping materials.

[0043] Specifically, the dimensions of the front-end shaping of the second link 702 and the third link 801 are carefully designed, which is the key factor restricting the folding angle. For example, the front end of the link may be designed into a specific arc, inclined plane, or a structure with protrusions and grooves. When the link rotates, these special-shaped parts will interfere with each other, thereby preventing the link from continuing to rotate and achieving the purpose of restricting the folding angle. When the link starts to rotate from the initial position and rotates to about 30 degrees, a certain part of the front-end shaping will come into contact with each other, generating resistance, making the link unable to continue rotating in this direction, thus restricting the minimum folding angle to 30 degrees; similarly, when the link rotates in the opposite direction and rotates to 180 degrees, that is, when the upper and lower links are in a straight line state, another part of the front-end shaping will resist each other, preventing the link from continuing to rotate and ensuring that the maximum folding angle is 180 degrees;

[0044] Among them, the structure with the rod split in the middle is relatively easy to process. Traditional integral connecting rod processing may require complex molds and processes. However, for the structure split in the middle, the two split parts can be processed separately first and then assembled, which reduces the processing difficulty and cost. Moreover, the two split parts are optimized in the connection part, which can disperse stress and improve the strength of the whole structure. When bearing external forces, the force can be more evenly distributed to the whole connecting rod, reducing the risk of local stress concentration, thus ensuring the reliability and durability of the structure. In addition, the structure with the rod split in the middle can avoid excessive friction and collision with the rubber coating layer or the outer wrapping material during the rotation of the connecting rod, and avoid excessive stress concentration in some parts of the connecting rod, thereby preventing stress from being transmitted to the outer wrapping material and causing the outer wrapping material to crack or deform. By evenly distributing stress, the integrity and aesthetics of the outer wrapping material are protected.

[0045] Taking the leg joint of the internal bone bracket of a high-fidelity toy as an example, this planar hinge structure is adopted. The upper and lower connecting rods are respectively connected to the front and rear parts of the leg, and the rivet rotating shaft serves as the rotation center. The front-end shape and size are designed so that the leg stops rotating at about 180 degrees when standing and about 30 degrees when bent to a certain extent, simulating real leg movements. The connecting rod structure split in the middle is convenient for processing and production, and at the same time ensures the firmness and movement accuracy of the leg joint. Moreover, this structure will not damage the soft rubber coating layer wrapped outside the connecting rod, making the toy look more beautiful and realistic.

[0046] Furthermore, the length of the connecting rod on the leg mechanism 5 is greater than the length of the connecting rod on the arm mechanism 6.

[0047] Furthermore, the entire internal skeleton is made of metal materials.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
