Description
Technical Field
[0001] The utility model relates to the technical field of toys, in particular to a leg movable joint structure and a humanoid toy. Background Art
[0002] The animation IP industry is growing larger and larger. In the animation IP industry, the characters in the animation works need to be produced and assembled into model toys. The human-shaped model toys, such as animation heroes, monsters, robots and other model toys, need to achieve a variety of postures and movements, such as standing, walking, running, squatting and other postures. In these different postures, the knees of the legs remain bent and also have to bear the weight of the entire model toy. For light human-shaped toys, the requirements of load-bearing and rotation can be met by the interference fit of bearings and shafts. However, on large doll models with heavier weight, this interference fit structure of bearings and shafts is easily destroyed by the weight of the entire model toy. Therefore, larger human-shaped toys are mostly locked at the knees after the posture is adjusted to prevent them from rotating, thereby ensuring that the knees can withstand the weight of the entire human-shaped toy.

[0031] The specific implementation modes of the present utility model are introduced with reference to the accompanying drawings.
[0032] refer to Figure 1 The figure is a schematic diagram of the three-dimensional structure of the legs of a humanoid toy, which includes a thigh 101, a calf 102 and a foot 103 from top to bottom. The leg movable joint structure is arranged at the knee between the thigh 101 and the calf 102. The leg movable joint structure can make the calf 102 rotate to a certain angle relative to the thigh 101, thereby realizing the posture adjustment of the bent legs of the humanoid toy.
[0033] refer to Figures 1 to 7A leg movable joint structure is arranged at the knee of a humanoid toy, comprising a rotary damper 1, a thigh connecting member 2 and a calf connecting assembly 3. The rotary damper 1 is horizontally placed at the connection between the thigh 101 and the calf 102 of the humanoid toy, the thigh connecting member 2 is fixed to the inner wall of the thigh 101, and the thigh connecting member 2 is provided with a first connecting sleeve 21 which is sleeved on the outer circumferential direction of the first rotating part 11 of the rotary damper 1; the calf connecting assembly 3 is arranged between the calf 102 and the rotary damper 1, and the calf connecting assembly 3 is arranged between the calf 102 and the rotary damper 1. The component 3 includes a first connecting member 31 and a second connecting member 32 respectively fixed on both sides of the inner wall of the calf 102. The first connecting member 31 is provided with a second connecting sleeve 33 which is sleeved on the outer circumferential direction of the second rotating part 12 of the rotary damper 1. The second connecting member 32 is provided with a limiting sleeve 34 which is sleeved on one end of the first connecting sleeve 21. A limiting structure 4 is arranged between the limiting sleeve 34 and the first connecting sleeve 21. The second connecting sleeve 33, the first connecting sleeve 21 and the limiting sleeve 34 are arranged side by side along the axial direction of the rotary damper 1.
[0034] In the leg movable joint structure of the present embodiment, the rotary damper 1 serves as a rotating component, which achieves the deceleration of the rotation between the thigh 101 and the calf 102 through its own damping, so that the legs of the human-shaped toy can bend at a certain angle at the knees and maintain it, which is convenient for the posture adjustment of the human-shaped toy and improves the user experience; the main body of the rotary damper 1 is made of metal material with strong bearing capacity. By coaxially arranging the first connecting sleeve 21 between the second connecting sleeve 33 and the limiting sleeve 34, it is ensured that the rotary damper 1 can stably maintain a horizontal state to avoid swaying, thereby improving the stability of the entire leg movable joint structure and extending the service life.
[0035] In order to ensure the stable installation of the rotary damper 1, in this embodiment, reference Figure 4 The first rotating part 11 and the second rotating part 12 of the rotary damper 1 are coaxially arranged, and the outer side walls of the first rotating part 11 and the second rotating part 12 are both provided with outer positioning planes 71, and the inner walls of the first connecting sleeve 21 and the second connecting sleeve 33 are both provided with inner positioning planes 72 that cooperate with the corresponding outer positioning planes 71.
[0036] It should be further explained that the second rotating part 12 enables the first rotating part 11 and the second rotating part 12 which are mounted on the first rotating part 11 to rotate relative to each other, and the rotation process is affected by the damping between the two. The first connecting sleeve 21 is fixed to the first rotating part 11, and the second connecting sleeve 33 is fixed to the second rotating part 12, so that the rotation between the thigh 101 installed with the first connecting sleeve 21 and the calf 102 installed with the second connecting sleeve 33 is affected by the damping between the first rotating part 11 and the second rotating part 12, so that the thigh 101 can remain motionless after rotating a certain angle relative to the calf 102, and maintain the adjusted posture unchanged.
[0037] It can be understood that, in such a configuration, the plane positioning between the inner positioning plane 72 and the outer positioning plane 71 enables better positioning between the first rotating part 11 and the first connecting sleeve 21, and between the second rotating part 12 and the second connecting sleeve 33. It is convenient to accurately sleeve the first connecting sleeve 21 and the second connecting sleeve 33 on the first rotating part 11 and the second rotating part 12, respectively, to prevent the first connecting sleeve 21 and the second connecting sleeve 33 from slipping off from the first rotating part 11 and the second rotating part 12, so that the rotary damper 1 is stably installed between the first connecting sleeve 21 and the second connecting sleeve 33.
[0038] In order to fix the rotary damper 1 to the first connecting sleeve 21 and the second connecting sleeve 33 respectively, in this embodiment, reference Figure 4 The first connecting sleeve 21 and the first rotating part 11 as well as the second connecting sleeve 33 and the second rotating part 12 are fixed by bolts 13 , and the bolts 13 and the axial direction of the rotary damper 1 are perpendicular to each other.
[0039] It can be understood that, with such an arrangement, screw holes 14 for mounting bolts 13 are provided on the outer positioning planes 71 of the first rotating part 11 and the second rotating part 12, and the first connecting sleeve 21 and the first rotating part 11, and the second connecting sleeve 33 and the second rotating part 12 are fixed by screws. The bolts 13 and the axial direction of the rotary damper 1 are perpendicular to each other, which facilitates the opening of the screw holes 14 and the installation of the bolts 13.
[0040] In order to limit the rotation angle, in this embodiment, reference Figure 5 and Figure 6 The first connecting sleeve 21 is provided with a limiting portion 41 extending into the limiting sleeve 34. The limiting portion 41 is provided with a limiting groove 42 along the circumferential direction. A limiting block 43 is provided on the inner wall of the limiting sleeve 34. The limiting block 43 is arranged parallel to the axial direction. The limiting block 43 is located in the limiting groove 42. The limiting angle of the limiting structure 4 formed by the limiting groove 42 and the limiting block 43 is less than 90°.
[0041] It can be understood that, with such an arrangement, the first rotating part 11 and the second rotating part 12 of the rotary damper 1 can rotate 360°, and the limiting structure 4 makes the rotation angle of the thigh 101 and the calf 102 generally less than 90°. In order to ensure the overall load-bearing performance of the leg movable joint structure, less than 60° is optimal.
[0042] In order to achieve angle limitation, in addition to setting the limiting groove 42 on the first connecting sleeve 21, the limiting groove 42 can also be set on the second connecting sleeve 33. In some other embodiments, the first connecting sleeve 21 is provided with a limiting portion 41 extending into the interior of the limiting sleeve 34, and the limiting portion 41 is convexly provided with a limiting block 43. The limiting sleeve 34 is provided with a limiting groove 42 along the circumferential direction, and the limiting block 43 is located in the limiting groove 42. The limiting angle of the limiting structure 4 formed by the limiting groove 42 and the limiting block 43 is less than 90°.
[0043] In order to stably install the thigh connecting member 2 on the inner wall of the thigh 101, in this embodiment, reference Figure 6 A mounting tube 5 extending into the calf 102 is provided at the lower end of the thigh 101, and the mounting tube 5 is fixed to the inner wall of the thigh 101. The rotary damper 1 is located in the mounting tube 5, and the thigh connecting member 2 is fixed inside the mounting tube 5. The mounting tube 5 is provided with an avoidance hole 51 for installing the first connecting member 31 and the second connecting member 32.
[0044] It can be understood that, with such an arrangement, the thigh connector 2 is fixed to the inner wall of the thigh 101 through the mounting tube 5, and the outer diameter of the mounting tube 5 is smaller than the inner diameter of the thigh 101 and the inner diameter of the calf 102, so that the mounting tube 5 can extend into the calf 102, so that the installation position of the first connecting sleeve 21 can reach the inside of the calf 102 and be arranged close to the rotary damper 1, so that the first connecting sleeve 21, the second connecting sleeve 33, and the limiting sleeve 34 can be arranged side by side on the rotary damper 1, ensuring that the rotary damper 1 is stably arranged inside the calf 102.
[0045] In order to prevent the first connecting sleeve 21 from swinging, in this embodiment, reference Figure 6 The thigh connector 2 includes a mounting frame 22, the first connecting sleeve 21 is located in the middle of the mounting frame 22, and the mounting frame 22 is respectively provided with a first mounting position 23 and a second mounting position 24 on both sides of the radial direction of the first connecting sleeve 21, and the first mounting position 23 and the second mounting position 24 are respectively fixed to the inner wall of the mounting tube 5 by a first screw 25 and a second screw 26, and the distance between the first screw 25 and the second screw 26 is greater than the outer diameter of the first connecting sleeve 21.
[0046] It can be understood that, with such an arrangement, the first connecting sleeve 21 is fixed to the mounting tube 5 through the mounting frame 22, and the larger area between the first mounting position 23 and the second mounting position 24 of the mounting frame 22 prevents the first connecting sleeve 21 from swinging, thereby improving the stability between the first connecting sleeve 21 and the rotary damper 1.
[0047] In order to stably install the calf connection assembly 3 on the inner wall of the calf 102, in this embodiment, refer to Figure 5A mounting seat 6 is provided on the upper part of the calf 102, and the mounting seat 6 is fixed to the inner wall of the calf 102. The first connecting member 31 and the second connecting member 32 are respectively fixed on both sides of the mounting seat 6. A avoiding groove 61 is provided in the middle part of the mounting seat 6, and the lower end of the mounting tube 5 extends into the avoiding groove 61.
[0048] It can be understood that, with such an arrangement, the first connecting member 31 and the second connecting member 32 of the calf connecting assembly 3 are fixed on the mounting seat 6, and are installed together on the inner wall of the calf 102 through the mounting seat 6. The mounting seat 6 with greater strength can ensure that the calf connecting assembly 3 can be more stably fixed on the inner wall of the calf 102, and the avoidance groove 61 is used to provide the lower end of the mounting tube 5 with rotation space to avoid collision between the lower end of the mounting tube 5 and the mounting seat 6. The margin of this rotation space is designed based on the mounting tube 5 rotating 60° relative to the mounting seat 6.
[0049] In order to stably fix the first connecting member 31 and the second connecting member 32 on the mounting base 6, in this embodiment, reference Figure 4 The first connecting member 31 and the second connecting member 32 are both provided with a support 35, and the mounting seat 6 is provided with a positioning groove 62 matching the shape of the support 35. The support 35 is clamped in the positioning groove 62, and the support 35 has a first mounting plate 36 and a second mounting plate 37 extending outward on both sides of the radial direction. The first mounting plate 36 and the second mounting plate 37 are respectively fixed to the inner wall of the calf 102 by a third screw 38 and a fourth screw 39, and the spacing between the third screw 38 and the fourth screw 39 is greater than the width of the support 35.
[0050] It can be understood that, with such a configuration, the positioning groove 62 cooperates with the support 35, so that the support 35 and the mounting seat 6 can be better positioned and connected, and the larger area formed between the first mounting plate 36 and the second mounting plate 37 can improve the stability between the support 35 and the mounting seat 6. After being fixed by screws, the support 35 can be effectively prevented from shaking relative to the mounting seat 6, thereby stably fixing the first connecting member 31 and the second connecting member 32 on the mounting seat 6.
[0051] The embodiment of the present application uses the rotary damper 1 as a rotating component, and uses its own damping to achieve the deceleration of the rotation between the thigh 101 and the calf 102, so that the legs of the human-shaped toy can be bent within the range of 0-60° at the knees, which is convenient for the posture adjustment of the human-shaped toy and improves the user experience; the thigh connecting member 2 and the calf connecting assembly 3 are installed respectively through the installation tube 5 and the installation seat 6. After the rotary damper 1 is installed between the thigh connecting member 2 and the calf connecting assembly 3, it is installed as a whole on the installation tube 5 and the installation seat 6, and finally assembled between the inner wall of the thigh 101 and the inner wall of the calf 102, which is convenient for installation and improves assembly efficiency.
[0052] The embodiment of the present application also provides a humanoid toy, including a thigh 101, a calf 102 and a sole 103. A leg movable joint structure of the first aspect is arranged between the thigh 101 and the calf 102, and an ankle joint structure 8 is arranged between the calf 102 and the sole 103. The leg movable joint structure is a joint structure with only one rotational degree of freedom with a rotation angle less than 90 degrees, and the ankle joint structure 8 is a joint structure with three orthogonal rotational degrees of freedom. The humanoid toy allows the legs to bend within a range of 0-60° at the knees through the leg movable joint structure, and the ankle joint structure 8 allows the ankles to rotate in three directions, which is convenient for adjusting the posture of the humanoid toy.
[0053] The ankle joint structure 8 includes a first rotational connection component 81, a second rotational connection component 82 and a third rotational connection component 83. The first rotational connection component 81 is placed horizontally on the inner wall of the calf 102, the third rotational connection component 83 is placed horizontally on the sole 103, and the second rotational connection component 82 is vertically arranged between the first rotational connection component 81 and the third rotational connection component 83 to form three orthogonal rotational degrees of freedom.
