Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0056] Figures 1 to 3 The present invention illustrates a multi-degree-of-freedom motion toy 10 in some embodiments. The multi-degree-of-freedom motion toy 10 includes an upper body 1, an arm assembly 2, an extension assembly 3, a lower body 4, and a leg assembly 5. The arm assembly 2 is movably connected to the upper body 1 through the extension assembly 3, the lower body 4 is movably connected to the upper body 1, and the leg assembly 5 is movably connected to the lower body 4.

[0057] It should be noted that the upper body 1 serves to support the movement of the extension component 3. The arm component 2 itself can also move relative to the extension component 3. The lower body 4 can move relative to the upper body 1. The leg component 5 can move relative to the lower body 4.

[0058] like Figures 1 to 7As shown, the upper body 1 has an extension groove 11. The arm assembly 2 includes a large arm 21 and a small arm 22. One end of the large arm 21 is provided with an arm groove 211, and the other end of the large arm 21 is rotatably connected to the small arm 22. The extension assembly 3 includes a movable shaft 31 and two shaft socket balls 32. The two shaft socket balls 32 are respectively disposed at both ends of the movable shaft 31. Each shaft socket ball 32 has a plurality of first contact domes 321 on its surface. One shaft socket ball 32 is rotatably disposed in the extension groove 11, and the other shaft socket ball 32 is rotatably disposed in the arm groove 211. Each first contact dome 321 is used to slide against the groove wall of the extension groove 11 and the groove wall of the arm groove 211.

[0059] The lower body 4 is movably connected to the upper body 1, and the lower body 4 has a leg recess groove 41. The leg assembly 5 includes a thigh 51, a leg recess ball 52, and a calf 53. One end of the thigh 51 is connected to the leg recess ball 52, and the other end of the thigh 51 is rotatably connected to the calf 53. The surface of the leg recess ball 52 is provided with a plurality of second contact domes 521. The leg recess ball 52 is rotatably disposed in the leg recess groove 41, and the second contact domes 521 slide against the groove wall of the leg recess groove 41.

[0060] It should be noted that the extension groove 11 is used to accommodate and constrain the bearing ball 32 in the extension assembly 3, allowing the bearing ball 32 to rotate at large angles within the extension groove 11. At the same time, the groove wall of the extension groove 11 provides a limiting function to prevent the bearing ball 32 from falling out, thereby ensuring the degree of freedom of movement of the extension assembly 3 relative to the upper body 1. The arm groove 211 is used to accommodate another bearing ball 32 in the extension assembly 3. Through the constraint of the groove wall of the arm groove 211, the bearing ball 32 can rotate freely within the arm groove 211, thereby realizing the multi-directional movement capability of the large arm 21 of the arm assembly 2 relative to the upper body 1.

[0061] The movable shaft 31 of the extension assembly 3 is used to connect two shaft socket balls 32. Several first contact round tops 321 on the shaft socket balls 32 are used to reduce frictional resistance when sliding against the groove walls of the extension socket 11 and the arm socket 211, ensuring the smoothness and stability of the rotation process and avoiding jamming.

[0062] The leg recess 41 is used to accommodate the leg ball 52 in the leg assembly 5. The limiting effect of the groove wall of the leg recess 41 allows the leg ball 52 to rotate at a large angle within the groove, thereby supporting the freedom of movement of the leg assembly 5 relative to the lower body 4. Several second contact domes 521 on the leg ball 52 are used to optimize the contact point when sliding against the groove wall of the leg recess 41, reducing wear and ensuring the smoothness and reliability of the leg assembly 5's movement.

[0063] The rotatable connection between the upper arm 21 and the forearm 22 of the arm assembly 2 is used to enable the forearm 22 to move independently relative to the upper arm 21, and the rotatable connection between the thigh 51 and the lower leg 53 of the leg assembly 5 is used to enable the lower leg 53 to move independently relative to the thigh 51. These rotatable connections together enhance the modular flexibility of the joint.

[0064] It should be noted that, through the synergistic effect of the aforementioned technical features, this embodiment achieves a large-angle movement capability for the multi-degree-of-freedom motion toy 10 in multiple key positions (such as between the upper body 1 and the arm assembly 2, inside the arm assembly 2, between the lower body 4 and the leg assembly 5, and inside the leg assembly 5). This increases the range of motion angles of the arm assembly 2 and the leg assembly 5, enabling the product to simulate more complex postures; enhances the flexibility and freedom of the overall structure, allowing for simultaneous movement of multiple joints; and optimizes rotational stability through the design of the grooves and contact domes, reducing component wear, thereby improving the product's durability and motion performance.

[0065] like Figures 1 to 5 As shown, in some embodiments of the multi-degree-of-freedom motion toy 10, the multi-degree-of-freedom motion toy 10 includes two arm assemblies 2, two extension assemblies 3 and two leg assemblies 5, with two extension slots 11 provided on the upper body 1 and two leg slots 41 provided on the lower body 4.

[0066] Two extension components 3 are rotatably connected to two extension slots 11 in a one-to-one correspondence; two arm components 2 are rotatably connected to two arm components 2 in a one-to-one correspondence; and two leg components 5 are rotatably connected to two leg slots 41 in a one-to-one correspondence.

[0067] Understandably, the two extension slots 11 independently accommodate the axial ball sockets 32 of the two extension components 3, ensuring that the rotational degrees of freedom of the two extension components 3 do not interfere with each other. The two leg slots 41 independently constrain the leg ball sockets 52 of the two leg components 5, realizing the mobility of the two leg components.

[0068] Two extension components 3 are rotatably connected to two extension slots 11 in a one-to-one correspondence, allowing the left and right extension components 3 to rotate independently at different angles. Two leg components 5 are rotatably connected to two leg slots 41 in a one-to-one correspondence, enabling the product to achieve asynchronous movement of the two leg components 5 (such as standing on one leg, standing forward and backward, standing sideways, splits, etc.).

[0069] It should be noted that, in this embodiment, the symmetrically distributed extended grooves 11 and leg grooves 41 enable the arms and legs of the multi-degree-of-freedom motion toy 10 to move synchronously or asynchronously, thus expanding the range of bionic motion and ensuring that the two sides do not interfere with each other, thereby improving the coordination of the movements.

[0070] like Figure 4 , Figure 8 and Figure 9As shown, in some embodiments of the multi-degree-of-freedom motion toy 10, the upper arm 21 is also provided with an arm joint groove 212, and two mutually symmetrical support shafts 2121 are provided in the arm joint groove 212.

[0071] The end of the forearm 22 is provided with an arm connecting part 221, and arm connecting sleeves 2211 are respectively provided on two opposite sides of the arm connecting part 221.

[0072] The arm connecting part 221 is movably inserted into the arm connecting groove 212, and each support shaft 2121 is movably inserted into the arm connecting sleeve 2211 in a corresponding manner; the forearm 22 rotates relative to the upper arm 21 through the arm connecting sleeve 2211 and the support shaft 2121.

[0073] Understandably, the arm joint groove 212 provides a receiving space to limit the arm connection portion 221, preventing the forearm 22 from detaching from the upper arm 21 and ensuring that the forearm 22 can rotate in a predetermined direction. The two support shafts 2121 are respectively inserted into the two arm connection sleeves 2211, which can distribute the force on the joint, improve durability, and enhance stability during rotation. The inner wall of the arm connection sleeve 2211 slides against the surface of the support shafts 2121, converting the rotation of the forearm 22 into a stable rotation about the axis of the two support shafts 2121.

[0074] It should be noted that the symmetrical insertion design of the double support shaft 2121 and the arm connecting sleeve 2211 significantly enhances the structural strength of the connection between the upper arm 21 and the lower arm 22, avoids the problem of easy wear of single-point support, and ensures that there is no radial sway during the rotation of the lower arm 22, thereby improving the stability of the product's movement.

[0075] like Figure 8 and Figure 9 As shown, in some embodiments of the multi-degree-of-freedom motion toy 10, each support shaft 2121 is provided with an annular groove 2122 around its periphery.

[0076] Damping stripes 2212 are provided on the inner and outer peripheral sidewalls of the arm connecting sleeve 2211, and several damping protrusions 2213 are provided on the arm connecting part 221, with each damping protrusion 2213 surrounding the two arm connecting sleeves 2211 respectively.

[0077] The arm connecting sleeve 2211 is movably inserted into the annular groove 2122, and each damping stripe 2212 slides against the groove wall of the annular groove 2122 and the support shaft 2121, and each damping protrusion 2213 slides against the groove wall of the arm connecting groove 212; the gap between the arm connecting sleeve and the support shaft is 0.1mm to 0.3mm, and the height of the damping stripe is 0.1mm to 0.5mm.

[0078] Understandably, the annular groove 2122 is used to accommodate the edge of the arm connecting sleeve 2211, restricting the axial displacement of the arm connecting sleeve 2211 and preventing it from dislodging from the support shaft 2121 during rotation. The damping stripes 2212 allow the product to increase the contact friction with the groove wall of the annular groove 2122 and the surface of the support shaft 2121 through the concave and convex texture, providing rotational resistance, thereby allowing it to be fixed after rotating to different angles.

[0079] It should be noted that configuring the gap between the arm connecting sleeve and the support shaft to 0.1mm to 0.3mm can ensure stability during relative movement while preventing loosening. The height of the damping stripe 2212 refers to the amount of protrusion of the damping stripe 2212 from its set position.

[0080] like Figure 8 and Figure 9 As shown, in some embodiments of the multi-degree-of-freedom motion toy 10, the groove of the arm connector 212 is provided with a clearance notch 2123 in the rotation direction of the arm connector 221. The clearance notch 2123 is inserted into the arm connector 221 when it rotates. The opening angle of the clearance notch is 120° to 150°.

[0081] Understandably, the opening direction of the clearance notch 2123 is aligned with the rotation trajectory of the arm connection 221, in order to extend the maximum rotation position of the arm connection 221, so that the arm connection 221 can rotate at a larger angle.

[0082] It should be noted that configuring the opening angle of the avoidance gap to 120° to 150° can significantly improve maneuverability.

[0083] like Figure 6 As shown, in some embodiments of the multi-degree-of-freedom motion toy 10, the groove of the extension slot 11 is provided with a plurality of upper limit position notches 111, each upper limit position notch 111 is inserted into the movable shaft 31 when it moves, and the depth of the upper limit position notch is 1.2 times the shaft diameter of the movable shaft.

[0084] Understandably, the upper limit position notch 111 is spaced at the edge of the groove of the extension recess 11, so as to allow the movable shaft 31 to be partially embedded when it rotates with the shaft recess ball 32 to different high positions, thereby releasing the travel constraint of the groove on the movable shaft 31 and expanding the movement angle of the movable shaft 31.

[0085] It should be noted that the upper limit position notch 111 provides multiple discrete limit position receiving points, enabling the extension component 3 to be stably docked at a larger tilt angle, significantly expanding the relative range of motion between the upper body 1 and the arm component 2, and enhancing the product's motion performance.

[0086] Specifically, the depth of the notch 111 at the upper limit position is 1.2mm to 3.1mm.

[0087] like Figure 7 As shown, in some embodiments of the multi-degree-of-freedom motion toy 10, the groove of the leg recess 41 is provided with several lower limit position notches 411, each of which is inserted into the thigh 51 when it moves.

[0088] Understandably, the notches 411 at various lower limit positions are spaced apart at the edge of the groove of the leg socket 41, so as to allow the end of the thigh 51 to be partially embedded when the thigh 51 of the leg assembly 5 moves to different positions, so as to avoid excessive rotational limitation on the thigh 51, and allow the thigh 51 to rotate within a larger angle range, thereby improving the flexibility of movement.

[0089] In some embodiments, the coverage of the first contact dome on the surface of the bearing ball is 30% to 50%.

[0090] Understandably, the area occupied by the first contact dome accounts for 30% to 50% of the surface area of ​​the nacelle.

[0091] Specifically, the diameter of the shank ball is 12 mm, and the diameter of the extended groove is 12.5 mm.

[0092] like Figure 2 and Figure 4 As shown, in some embodiments of the multi-degree-of-freedom motion toy 10, the leg assembly 5 further includes a knee joint 54, on which two rotating connecting parts 541 are provided;

[0093] like Figure 4 as well as Figures 10 to 12 As shown, a first rotating groove 511 is provided at one end of the thigh 51, and a first connecting part 5111 is provided in the first rotating groove 511; a second rotating groove 531 is provided at one end of the lower leg 53, and a second connecting part 5311 is provided in the second rotating groove 531.

[0094] One of the rotating connecting parts 541 is rotatably disposed in the first rotating groove 511, and the other rotating connecting part 541 is rotatably disposed in the second rotating groove 531, and the two rotating connecting parts 541 are respectively inserted and engaged with the first connecting part 5111 and the second connecting part 5311.

[0095] Understandably, the two rotating connecting parts 541 provided on the knee joint 54 greatly release the rotational freedom of the thigh 51 and the lower leg 53, avoid physical interference between the thigh 51 and the lower leg 53 due to their respective shapes when they rotate relative to each other, and effectively improve the degree of freedom of movement of the leg assembly 5.

[0096] like Figures 1 to 5As shown, in some embodiments of the multi-degree-of-freedom motion toy 10, the multi-degree-of-freedom motion toy 10 also includes an extension component 6, which includes an extension shaft 61 and two extension balls 62.

[0097] like Figure 4 and Figure 5 As shown, the upper body 1 is also provided with a first expansion groove 12, and the lower body 4 is also provided with a second expansion groove 42. One expansion ball 62 is rotatably disposed in the first expansion groove 12, and the other expansion ball 62 is rotatably disposed in the second expansion groove 42.

[0098] Understandably, in this embodiment, two extended ball sockets 62 are connected by an extended shaft 61 to form a two-degree-of-freedom rotational structure. On the one hand, the extended shaft 61 allows for a gap between the upper body 1 and the lower body 4, preventing mutual interference when they move relative to each other; on the other hand, the extended ball sockets 62 at both ends of the extended shaft 61 also allow the upper body 1 and the lower body 2 to move independently without affecting each other. The first extended groove 12 and the second extended groove 42 each independently accommodate one extended ball socket 62, providing rotational space and constraining the release of the extended ball socket 62.

[0099] It should be noted that by setting the extension component 6 in this embodiment, the upper body 1 and the lower body 4 can independently perform compound actions such as pitching and bending, thereby improving the realism of the product's movements.

[0100] like Figure 1 and Figure 2 As shown, in some embodiments of the multi-degree-of-freedom motion toy 10, the multi-degree-of-freedom motion toy 10 also includes a head assembly 7; as Figures 3 to 5 as well as Figure 12 As shown, the head assembly 7 includes a head shaft 71, a head anti-slip ball 72, and a head smooth ball 73. One end of the head shaft 71 is connected to the head anti-slip ball 72, and the other end of the head shaft 71 is connected to the head smooth ball 73. The surface of the head anti-slip ball 72 is provided with a plurality of anti-slip domes 721.

[0101] The upper body 1 is also provided with a head connection groove 13, and the anti-slip ball 72 of the head is rotatably disposed in the head connection groove 13, and the anti-slip round top 721 slides against the groove wall of the head connection groove 13.

[0102] Understandably, the anti-slip dome 721 on the surface of the anti-slip ball 72 reduces the contact area with the groove wall of the head connector 13, thus reducing wear. The smooth ball 73 on the head allows users to quickly replace the product head, while also preventing excessive wear on the connection point to the external head (not shown).

[0103] The non-slip dome 721 provides a certain amount of damping to prevent the head assembly 7 from accidentally sagging due to gravity; the smooth ball 73 ensures smooth horizontal and vertical rotation of the head.

[0104] like Figure 4 As shown, in some embodiments of the multi-degree-of-freedom motion toy 10, the upper body 1 is provided with an upper reinforcing rib 14, and the lower body 4 is provided with a lower reinforcing rib 43.

[0105] Understandably, the upper reinforcing rib 14 enhances the strength of the upper body 1 and prevents it from twisting or deforming. The lower reinforcing rib 43 strengthens the lower body 4. Thus, the durability of the product can be improved through this embodiment.

[0106] Figure 13 The integrated injection mold 20 in some embodiments of the present invention is shown. The integrated injection mold 20 includes an upper mold 30, an upper mold core 40, a lower mold 50 and a lower mold core 60. The upper mold core 40 is connected to the upper mold 30 and the lower mold core 60 is connected to the lower mold 50.

[0107] When the upper mold 30 and the lower mold 50 are closed, the lower mold core 60 and the upper mold core 40 together define the injection cavity 70. The injection cavity 70 is used to inject plastic material and mold a multi-degree-of-freedom action toy that can be formed according to any of the above technical solutions. The draft angle of the injection cavity is 1° to 3°.

[0108] It should be noted that the upper mold 30 and lower mold 50 are respectively aligned and installed on the injection molding equipment. During the injection molding process, the injection molding equipment drives the upper mold 30 and lower mold 50 to close. After the molds close, the upper mold core 40 and lower mold core 60 will abut against each other, thus forming an injection cavity 70. Subsequently, the injection molding equipment injects the rubber material into the integrated injection mold 20. The rubber material flows along the channels on the integrated injection mold 20 into the injection cavity 70 and fills the injection cavity 70. After the rubber material cools and solidifies, a multi-degree-of-freedom motion toy 10 will be formed in the injection cavity 70. In this way, the production efficiency of the product can be improved through the content of this embodiment.

[0109] It should also be noted that the injection mold in this embodiment can mold all the moving joints on the toy in one go, which greatly improves the production efficiency of the product.

[0110] Furthermore, in actual production, the temperature of the injection cavity 70 can be controlled between 180°C and 220°C, and the cooling time of the rubber compound can be between 20 and 30 seconds.

[0111] The following are the beneficial effects of implementing this utility model:

[0112] This utility model relates to a multi-degree-of-freedom motion toy and an integrated injection mold. The integrated injection mold is used to injection mold the multi-degree-of-freedom motion toy. In this multi-degree-of-freedom motion toy, by rotating the axle ball in the extension groove and arm groove respectively, the axle ball can rotate at a larger angle within the groove, and the groove wall only serves to prevent the ball from falling out; thereby realizing the movement of the arm assembly within a larger angle range and improving the product's motion angle.

[0113] At the same time, the arm assembly can be fixed by inserting the ball joint into the extension groove and the arm groove, and the degree of freedom of the two when rotating relative to each other can be guaranteed.

[0114] Furthermore, the extension slots on the upper body allow the extension components to move; the arm slots allow the upper arm to move; the arm assembly is divided into a relatively movable upper arm and forearm; the leg slots allow the thigh to move; the leg assembly is divided into a relatively movable thigh and lower leg. In this way, the multi-degree-of-freedom motion toy can move in multiple positions, greatly improving the product's flexibility.
