Description

Technical Field

[0001] This utility model relates to the field of toy technology, specifically to a building block joint body and toy. Background Technology

[0002] Existing humanoid dolls are very popular because their appearance is very similar to that of humans. In order to change the current situation where the fixed joints prevent movement and result in low simulation, the joints are designed to be rotatable, which improves the simulation of the toys.

[0003] However, for some smaller toy joints (e.g., characters with a height between 10 and 12 cm), in order to resolve the contradiction between stability and good rotational force during joint rotation, it is often necessary to increase the size of the joint. However, increasing the size can easily damage the appearance of the product and affect its overall aesthetics. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of this utility model is to provide a building block joint body and toy.

[0005] According to the present invention, a modular joint body includes body blocks and shoulder blocks, wherein the shoulder blocks are rotatable relative to the body blocks. The body block has an assembly slot, and the shoulder block has a pivot. The pivot can be detachably fitted into the assembly slot and can rotate relative to the assembly slot. The pivot and the assembly slot are both interference-fitted in the radial and axial directions; or The shoulder block has an assembly hole, and the body block has a receiving groove. One end of the shoulder block with the assembly hole extends into the receiving groove and is integrally injection molded with a mating column so that the shoulder block is non-removably rotatably mated with the body block.

[0006] Preferably, the shoulder block includes a connecting end and a joint body, the connecting end being integrally formed with the joint body, and the pivot or mounting hole being located on the connecting end. Preferably, the connecting end has a cross-section that is wider at the top and narrower at the bottom.

[0007] Preferably, the joint body has a fan-shaped structure. Preferably, the joint body has a first splicing structure. Preferably, the first splicing structure is a ball head or ball socket structure.

[0008] Preferably, the lower end of the rotating shaft is also provided with a limiting platform, which can limit the rotation of the shoulder block when the shoulder block rotates relative to the body block.

[0009] Preferably, the inner surface of the shoulder block and the side of the body block opposite to the inner surface of the shoulder block are both flat. Preferably, the shoulder block can rotate relative to the body block and can switch between a first position and a second position. When the shoulder block is in the first position, the flat surface of the inner surface of the shoulder block contacts and abuts against the flat surface of the body block, thereby limiting the rotation of the shoulder block inward. When the shoulder block is in the second position, the limiting platform abuts against the inner wall of the assembly groove, thereby limiting the rotation of the shoulder block outward. Preferably, the opening of the assembly groove is an outward-opening structure.

[0010] Preferably, the interference fit between the rotating shaft and the mounting groove in the radial direction is 0.03–0.07 mm. Preferably, the interference fit between the rotating shaft and the mounting groove in the radial direction is 0.04–0.06 mm. Preferably, the interference fit between the rotating shaft and the mounting groove in the radial direction is 0.05 mm.

[0011] Preferably, the interference fit between the rotating shaft and the mounting groove in the axial direction is 0.05–0.1 mm. Preferably, the interference fit between the rotating shaft and the mounting groove in the axial direction is 0.06–0.09 mm. Preferably, the interference fit between the rotating shaft and the mounting groove in the axial direction is 0.07–0.08 mm.

[0012] Preferably, the interference fit between the mounting hole and the mating post is 0.02–0.04 mm. Preferably, the interference fit between the mounting hole and the mating post is 0.03 mm.

[0013] Preferably, the mating post has a cylindrical structure. Preferably, the mating post has a notch. Preferably, the length of the mating post in contact with the assembly hole is 3-4 mm.

[0014] A toy according to the present invention includes the aforementioned building block joint body.

[0015] Preferably, the shoulder blocks spliced ​​on both sides of the body block form a butterfly shoulder structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention solves the contradiction between stability and good rotational force during joint rotation in small toys by setting the joint size to an interference fit with the mounting groove in both the length and radial directions of the rotating shaft, or by configuring mounting holes on the shoulder blocks and configuring fitting posts integrally injection molded with the mounting holes on the body blocks, so that the shoulder blocks cannot be disassembled and rotate with the body blocks. It does not require increasing the size of the joints, ensures the overall aesthetics of the product, and has a simple structure that is easy to implement. Attached Figure Description

[0019] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0020] Example 1: This utility model provides a modular joint body, such as... Figure 1 , Figure 2 , Figure 3 As shown, it includes a body block 1 and a shoulder block 2. The shoulder block 2 can rotate relative to the body block 1. Specifically, the body block 1 has an assembly groove 11, and the shoulder block 2 has a rotating shaft 211. The rotating shaft 211 can be detachably matched and assembled into the assembly groove 11, and the rotating shaft 211 can rotate relative to the assembly groove 11. In order to solve the contradiction between the stability of rotation and the rotational force between the rotating shaft 211 and the assembly groove 11, the rotating shaft 211 and the assembly groove 11 are both set to interference fit in the radial direction and the axial direction.

[0021] like Figure 1 , Figure 2 As shown, the shoulder block 2 includes a connecting end 21 and a joint body 22. The connecting end 21 and the joint body 22 are integrally formed. The pivot 211 is located on the connecting end 21. The cross-section of the pivot 211 is wider at the top and narrower at the bottom, as shown. Figure 3 As shown, the opening of the assembly groove 11 is an outward-expanding structure, which is the widest part of the opening and gradually narrows inward from the end of the opening. This facilitates the rapid entry of the rotating shaft 211 into the assembly groove 11 during assembly.

[0022] Furthermore, a limiting platform 212 is also provided at the lower end of the rotating shaft 211. The inner side of the shoulder block 2 and the side of the body block 1 facing the inner side of the shoulder block 2 are both flat. When the shoulder block 2 rotates relative to the body block 1, the limiting platform 212 can limit the rotation of the shoulder block 2. Specifically, the shoulder block 2 can rotate relative to the body block 1 and can switch between a first position and a second position. When the shoulder block 2 is in the first position, the flat surface of the inner side of the shoulder block 2 contacts and abuts against the flat surface of the body block 1, thereby limiting the rotation of the shoulder block 2 in the inward direction by the body block 1. When the shoulder block 2 is in the second position, such as Figure 5 As shown, the limiting platform 212 abuts against the inner wall of the assembly groove 11 to limit the rotation of the body block 1 to the shoulder block 2 in the outward direction.

[0023] like Figure 3 As shown, the cross-section of the joint body 22 is fan-shaped, and the shoulder blocks 2 spliced ​​on both sides of the body block 1 are like the wings of two butterflies. Therefore, the shoulder blocks 2 form the structure of butterfly shoulders.

[0024] Furthermore, the joint body 22 has a first splicing structure 221, such as... Figure 2 As shown, the first splicing structure 221 is a ball-head or ball-socket structure, which can be used to connect the arm blocks of the puppet.

[0025] In this embodiment, the monochrome joints require user assembly, enhancing the user's assembly experience. The body block 1 and shoulder block 2 are injection molded separately, allowing the joints to achieve good mechanical strength and rotational force despite their small size. This avoids blindly increasing joint size for strength and rotational force, which could compromise the product's appearance. Furthermore, a suitable interference fit provides excellent insertion and removal feel and rotational force. In this application, the interference fit between the shaft 211 and the mounting groove 11 in the radial direction is 0.03–0.07 mm, preferably 0.04–0.06 mm, for example, 0.05 mm. The interference fit between the shaft 211 and the mounting groove 11 in the axial direction is 0.05–0.1 mm. Preferably, the interference fit between the rotating shaft 211 and the assembly groove 11 in the axial direction is 0.06 to 0.09 mm, for example, 0.07 to 0.08 mm. This will provide better rotational force and assembly / disassembly force, good elasticity and good mechanical strength, a good insertion and removal experience, and a good lifespan requirement.

[0026] This utility model also provides a toy, including a block joint body. The toy can be a doll toy, an animal toy, an anime character, etc., and can be flexibly applied according to actual scenarios.

[0027] Example 2: This embodiment is a variation of Embodiment 1. The difference is that the shoulder block 2 has an assembly hole 213, and the body block 1 has a receiving slot 12. Figure 6 , Figure 7 As shown, one end of the shoulder block 2 with the mounting hole 213 extends into the receiving groove 12 and is integrally injection molded through the mating post 13, making the shoulder block 2 and the body block 1 non-detachable, and allowing for rotational engagement. It should be noted that in this embodiment, integral injection molding refers to the shoulder block 2 and the mating post 13 being injection molded in the same mold, so that the mating post 13 is not assembled into the mounting hole 213 by splicing, but rather matched into the mounting hole 213 through injection molding, thus achieving both rotational function and non-detachability.

[0028] In this embodiment, the shoulder block 2 includes a connecting end 21 and a joint body 22. The connecting end 21 and the joint body 22 are integrally formed, and the assembly hole 213 is located on the connecting end 21.

[0029] In this embodiment, the shoulder block 2 and the body block 1 are two-color integrated joints, which do not require assembly by the user or the factory. They are injection molded as a whole, which makes it convenient for users to assemble models and saves costs. In addition, the joints are made small in size but still have good mechanical strength and rotational force. There is no need to blindly increase the joint size for the sake of strength and rotational force, which would damage the product appearance.

[0030] Furthermore, the mating post 13 and the mounting hole 213 cooperate to provide rotational force. The mating post 13 preferably adopts a cylindrical structure. A notch 131 is provided on the mating post 13 to enhance the rotational force. The contact length between the mating post 13 and the mounting hole 213 is controlled between 3 and 4 mm. The notch 131 on the mating post 13 generates an interference fit during rotation, further enhancing the rotational force. The interference fit between the mounting hole 213 and the mating post 13 is controlled between 0.02 and 0.04 mm, preferably 0.03 mm. The joint rotational force can be controlled between 2 and 5 N·cm. This rotational force can be guaranteed even after life testing, resulting in the best user experience.

[0031] Taking Example 1 as an example, the assembly process of the body block 1 and the shoulder block 2 is as follows: During the insertion of the shoulder block 2 into the body block 1, the pivot 211 and the mounting slot 11 are interference-fitted. The pivot 211 compresses and deforms the mounting slot 11, causing it to slightly flare outwards. After the pivot 211 is inserted into the mounting slot 11, it enters a tight fit. The mounting slot 11 then retracts from its compressed and deformed state, clamping the pivot 211, producing a "click" sound, indicating that the assembly is complete and providing good feedback to the user. The interference fit between the pivot 211 and the mounting slot 11 generates rotational force, and different amounts of interference in the pivot hole provide different rotational and insertion / removal forces.
