Description
Technical Field
[0001] This invention relates to the field of toy technology, specifically to a hip joint body and toy. Background Technology
[0002] In the design of lower limb joint structures for humanoid robots or biomimetic mechanical devices, to achieve complex movements such as walking, squatting, and leg folding, it is usually necessary to set up multi-degree-of-freedom rotational joints between the hip joint and the thigh segment. Currently, most mainstream lower limb designs adopt a leg-folding movement mode where the thigh structures directly converge towards the midline to simulate the human leg-folding posture. However, in existing technologies, the crotch joint structure located between the legs is often a monolithic block structure with a fixed volume and spatial position. During the process of the thighs rotating and folding towards the midline, the crotch structure interferes with the inner walls of the thighs, such as... Figure 6 As shown, the angle of thigh rotation is restricted, making it impossible to fully bring the legs together.
[0003] This interference problem has a series of negative impacts: First, it restricts the freedom of movement, making it impossible to achieve the normal human posture of legs together, affecting the biomimetic effect and the accuracy of movement reproduction; second, to avoid interference, existing designs are usually forced to increase the gap between the crotch structure and the inner thigh, resulting in a bulky and larger overall structure, which is not conducive to miniaturization and lightweight design; third, some designs avoid interference by sacrificing the rotation angle of the hip joint or using an outward swing structure, which leads to a decrease in the flexibility of walking, turning and other movements. Therefore, there is an urgent need for a new hip joint structure that can solve the problem of crotch and thigh interference and enable unobstructed leg-to-leg movement. Summary of the Invention

Detailed Implementation
[0046] 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 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.
[0047] Example 1: This invention provides a hip joint body, such as Figures 1 to 5 As shown, the system includes a support body 1, a left connecting component, a right connecting component, a left building block 6, and a right building block 7. The right end of the left connecting component is rotatably disposed on the left side of the support body 1. The proximal end of the left building block 6 is rotatably disposed on the left end of the left connecting component and has a left sliding stroke in the axial direction of the left connecting component. The left end of the right connecting component is rotatably disposed on the right side of the support body 1. The proximal end of the right building block 7 is rotatably disposed on the right end of the right connecting component and has a right sliding stroke in the axial direction of the right connecting component. This allows the left leg connected to the left building block 6 and the right leg connected to the right building block 7 to be adjusted to a closed position. Specifically, both the left building block 6 and the right building block 7 are preferably equipped with outer armor. The outer armor can be decorated in various ways, such as with shapes, colors, and textures, to increase the realism of the character.
[0048] Furthermore, the left and right legs can switch between a together position and an extended position, such as... Figure 12As shown, in this embodiment, since both the left block 6 and the right block 7 are equipped with outer armor, when both the left block 6 and the right block 7 rotate to a vertical position and continue to rotate towards each other, the outer armor of the left block 6 and the outer armor of the right block 7 come into contact and abut against each other, preventing the left block 6 from rotating further to the right and the right block 7 from rotating further to the left, thus achieving a closed state between the left and right legs. It should be noted that when the left block 6 rotates to a vertical position and continues to rotate to the right, its axis N forms an angle θ with the body's midline M, as shown... Figure 11 As shown, when the right block 7 rotates to the vertical position and continues to rotate to the left, its axis forms an angle α with the body's midline M. These two angles can be adjusted according to the actual product requirements. For example, they can be adjusted by changing the lengths of the left and right sliding strokes to meet the needs of motion simulation. In practical applications, for different shapes of hips, thighs, and calves, and considering the connection structures, lengths, thicknesses, and armor configurations, the angle at which the left block 6 rotates to the vertical position and continues to rotate to the right, and the angle at which the right block 7 rotates to the vertical position and continues to rotate to the left, may differ when reaching the closed position. The closed position in this invention can be flexibly understood according to the actual application scenario.
[0049] It should be emphasized that, compared with the prior art, the left block 6 and the right block 7 in this invention can continue to rotate to the right after rotating to the vertical position, and the right block 7 can continue to rotate to the left after rotating to the vertical position. Moreover, they can continue to rotate at a certain angle, such as 10° or 12°, which greatly increases the flexibility of movement, improves the simulation, and enhances the fun.
[0050] In the extended position, the left and right legs form a split, which can also create a straight line, such as... Figure 9 As shown in (1), a simulated splits motion effect is achieved. When the hip joint in this invention is in a splits position, the split angle can reach more than 180°, as shown in (1). Figure 9 (2) As shown. In addition, when the left block 6 or the right block 7 is rotated in the left or right direction, the rotation angle relative to the support body 1 is allowed to exceed 90°, making the entire structure more flexible, more realistic, and increasing the overall structure's interest.
[0051] Furthermore, the left end of the left connecting component has a left ball sleeve 21 that is freely slidable, and the left sliding stroke is achieved by sliding the left ball sleeve 21. The proximal end of the left block 6 is disposed outside the left ball sleeve 21 and rotates in cooperation with the left ball sleeve 21. The right end of the right connecting component has a right ball sleeve 31 that is freely slidable, and the right sliding stroke is achieved by sliding the right ball sleeve 31. The proximal end of the right block 7 is disposed outside the right ball sleeve 31 and rotates in cooperation with the right ball sleeve 31.
[0052] like Figures 1 to 5 As shown, the left connecting component includes a left middle block 2 and a left ball sleeve 21, and the right connecting component includes a right middle block 3 and a right ball sleeve 31. The proximal ends of the left middle block 2 and the right middle block 3 are rotatably mounted on the support 1. The left ball sleeve 21 is slidably fitted onto the distal end of the left middle block 2, and the right ball sleeve 31 is slidably fitted onto the distal end of the right middle block 3. During actual posture adjustment, due to the adjustment of the movement, the left ball sleeve 21 can adaptively slide freely on the left middle block 2, and the right ball sleeve 31 can adaptively slide freely on the right middle block 3. Specifically, the left ball sleeve 21 and the left cover 4 can slide along the axis of the left middle block 2, and the right ball sleeve 31 and the right cover 5 can slide along the axis of the right middle block 3. One end of the left block 6 is rotatably mounted on the outside of the left ball sleeve 21, and one end of the right block 7 is rotatably mounted on the outside of the right ball sleeve 31. When the left block 6 and the right block 7 are rotated to adjust their state, the left ball sleeve 21 on the left middle block 2 and the right ball sleeve 31 on the right middle block 3 both have a sliding stroke, which allows the joint to adjust its posture by sliding left and right during rotation. This can adaptively avoid interference with other components during joint rotation, making the joint movement change more flexible and the flexibility and simulation higher.
[0053] To enhance the aesthetics of the joint, the left connecting component also includes a left concealing cover 4, and the right connecting component also includes a right concealing cover 5, such as... Figure 5 As shown, the left cover 4 is rotatably disposed outside the left ball sleeve 21, and the right cover 5 is rotatably disposed outside the right ball sleeve 31. The left cover (4) is provided with a left rotating shaft 42, and the right cover 5 is provided with a right rotating shaft 52. The left block 6 is rotatably disposed outside the left cover 4 and can rotate relative to the left cover 4 around the left rotating shaft 42. The right block 7 is rotatably disposed outside the right cover 5 and can rotate relative to the right cover 5 around the right rotating shaft 52. During rotation, the left cover 4 can partially or completely cover the ends of the left ball sleeve 21 and the left middle block 2, and the right cover 5 can partially or completely cover the ends of the right ball sleeve 31 and the right middle block 3. When viewed from the outside, the internal parts are not visible, thus playing a role in concealing ugliness and improving the aesthetics of the entire structure.
[0054] like Figure 1 , Figure 2As shown, the left cover 4 is provided with a left protrusion 41, the left block 6 is provided with a left edge end 64, the right cover 5 is provided with a right protrusion 51, and the right block 7 is provided with a right edge end 74. When in the extended state, the left edge end 64 abuts against the left protrusion 41, and the right edge end 74 abuts against the right protrusion 51. The above structure configuration can make the left block 6 and the left cover 4, and the right block 7 and the right cover 5 have a limiting structure, so that the linkage of the parts through the limiting structure is more precise when the action is switched.
[0055] like Figure 1 , Figure 5 , Figure 7 As shown, one end of the left middle block 2 is a left connecting shaft 23. The center of the end of the left connecting shaft 23 has a left receiving groove 232. One or both sides of the end of the left connecting shaft 23 are provided with a left limiting protrusion 231. The left ball sleeve 21 has a left assembly hole 213, a left guide groove 211 disposed on the inner wall of the left assembly hole 213, and a left partition 212 located in the middle of the inner wall of the left assembly hole 213. During assembly, when the left connecting shaft 23 is assembled into the left assembly hole 213, the left limiting protrusion 231 moves along the left guide groove 212. The guide groove 211 slides, causing the left receiving groove 232 to deform and narrow as it passes the left partition 212. After the left limiting protrusion 231 passes the left partition 212, the left receiving groove 232 returns to its original shape. The left ball sleeve 21 can slide between the left limiting protrusion 231 and the root of the left connecting shaft 23, providing axial flexibility along the connecting shaft direction for the joint's deformation. During axial sliding, the left partition 212 acts as a limiting stop for the left limiting protrusion 231, ensuring stability during the sliding process. It should be noted that the left limiting protrusion 231 is equipped with a left-inclined surface for easy assembly.
[0056] Furthermore, the other end of the left middle block 2 is the left assembly end 22. The support body 1 has a support shaft 11. The left assembly end 22 is assembled on the support shaft 11. The left assembly end 22 can rotate relative to the support shaft 11, which increases the overall flexibility of the joint.
[0057] like Figure 1 , Figure 5 , Figure 8As shown, one end of the right middle block 3 is the right connecting shaft 33, and the other end of the right middle block 3 is the right assembly end 32. The right assembly end 32 is assembled onto the support shaft 11, and the right assembly end 32 can rotate relative to the support shaft 11. The right connecting shaft 33 has a right receiving groove 332 at its center at its end. A right limiting protrusion 331 is arranged on one or both sides of the end of the right connecting shaft 33. The right ball sleeve 31 has a right assembly hole 313, a right guide groove 311 arranged on the inner wall of the right assembly hole 313, and a right partition 312 located in the middle of the inner wall of the right assembly hole 313. During assembly, the right connecting shaft 33 enters the right assembly hole 313 and the right limiting protrusion 331 slides along the right guide groove 311 and deforms when passing the right partition 312, causing the right receiving groove 332 to narrow. After passing the right partition 312, the deformation returns to its original shape. The right ball sleeve 31 can slide between the right limiting protrusion 331 and the root of the right connecting shaft 33, providing axial flexibility along the connecting shaft direction for the deformation of the joint. During axial sliding, the right partition 312 forms a limiting block on the right limiting protrusion 331, which is beneficial to the stability of the overall structure. To improve assembly efficiency, the right limit protrusion 331 is equipped with a right inclined surface, which facilitates rapid assembly.
[0058] like Figure 1 , Figure 5 , Figure 7 , Figure 8 As shown, the left connecting shaft 23 of the left middle block 2 and the right connecting shaft 33 of the right middle block 3, which are assembled on the support shaft 11, have their axes on the same plane, so that the left connecting shaft 23 and the right connecting shaft 33 are symmetrically arranged after assembly. This ensures more freedom and is beneficial to the aesthetics of the whole structure.
[0059] like Figure 1 , Figure 3 , Figure 5 As shown, the other end of the left block 6 is equipped with a first splicing structure 63, and the other end of the right block 7 is equipped with a second splicing structure 73. Both the first splicing structure 63 and the second splicing structure 73 are used to splice other blocks. The first splicing structure 63 is preferably a ball head or a ball socket, and the second splicing structure 73 is preferably a ball head or a ball socket. By adopting a ball head or ball socket structure, the entire joint has more degrees of freedom of movement, which is beneficial to improving the simulation accuracy of the entire joint.
[0060] like Figure 1 , Figure 5As shown, the left block component 6 includes a first left block cover 61 and a second left block cover 62. The first left block cover 61 is spliced onto the second left block cover 62. Part or all of the left cover 4 is disposed in the left block component 6. The outer surface of the left cover 4 has a first arc-shaped curved surface. The interior of the left block component 6 has a structure that matches the first arc-shaped curved surface, so that the left cover 4 and the left block component 6 can rotate and engage. The structure and principle of the rotational engagement are similar to the engagement structure of a ball head and a ball socket.
[0061] Furthermore, the right block component 7 includes a first right block cover 71 and a second right block cover 72. The first right block cover 71 is spliced onto the second right block cover 72. Part or all of the right cover 5 is disposed in the right block component 7. The outer surface of the right cover 5 has a second arc-shaped curved surface. The interior of the right block component 7 has a structure that matches the second arc-shaped curved surface, so that the right cover 5 and the right block component 7 can rotate and engage. The structure and principle of the rotational engagement are similar to the engagement structure of a ball head and a ball socket.
[0062] It should be noted that the left block 6, the left cover 4, and the left ball sleeve 21 form a joint structure similar to a universal joint. The left block 6 can rotate relative to the left cover 4, the left cover 4 can rotate relative to the left ball sleeve 21, and the left ball sleeve 21 can slide on the left connecting shaft 23. The right block 7, the right cover 5, and the right ball sleeve 31 form a joint structure similar to a universal joint. The right block 7 can rotate relative to the right cover 5, the right cover 5 can rotate relative to the right ball sleeve 31, and the right ball sleeve 31 can slide on the right connecting shaft 33. This allows the entire hip structure to achieve large-angle adjustments to the thigh posture through multi-level rotation and sliding. This gives the left block 6 and the right block 7 not only a degree of freedom of left and right movement, but also a degree of freedom of forward and backward movement. The ability of the left and right legs to move together, in a split, or in any of these states relies on the rotational engagement between the proximal end of the left middle block 2 and the support body 1, the rotational engagement between the proximal end of the right middle block 3 and the support body 1, the sliding engagement between the left ball sleeve 21 and the left connecting shaft 23, the sliding engagement between the right ball sleeve 31 and the right connecting shaft 33, the rotational engagement between the left cover 4 and the left ball sleeve 21, the rotational engagement between the right cover 5 and the right ball sleeve 31, the rotational engagement between the left block 6 and the left cover 4, and the rotational engagement between the right block 6 and the left cover 4. At least one of the following relationships—the rotational coordination between block 7 and the right cover 5, the rotational coordination between the left block 6 and the left leg, and the rotational coordination between the right block 7 and the right leg—not only solves the problem of not being able to bring the legs together due to groin interference, but also solves the problem of complex motion simulation such as forward and backward movement, hip widening and narrowing. The rotational movements are more flexible, giving the hips more freedom of movement, and can also achieve movement changes that are different from those of ordinary people. The high flexibility of posture adjustment between the left block 6 and the right block 7 in this invention is conducive to improving the joint simulation and increasing the fun of the toy.
[0063] like Figure 1 , Figure 5 As shown, the support body 1 has a cover 8 on the outside. The cover 8 includes a front block cover 81 and a rear block cover 82. The front block cover 81 is spliced onto the rear block cover 82. The splicing method is preferably a male and female joint. The ends of the support body 1 are spliced onto the front block cover 81 and / or the rear block cover 82. The specific splicing method can be flexibly selected according to different scenarios.
[0064] This invention also provides a toy, including a hip joint, preferably a block figure capable of crossing its legs while standing. Specifically, both the left block 6 and the right block 7 have degrees of freedom to twist forward or backward relative to the support 1. When the left block 6 and the right block 7 are twisted forward and backward respectively, a crossing leg movement can be achieved. Figure 10 As shown, this enhances the fun of the toy.
[0065] Example 2: The difference between this embodiment and embodiment 1 is that neither the left block 6 nor the right block 7 is equipped with an outer armor. When the left block 6 and the right block 7 rotate to the vertical position and continue to rotate towards each other, the left leg connected to the left block 6 and the right leg connected to the right block 7 come into contact and abut against each other on opposite sides, so that the left block (6) can no longer rotate to the right and the right block (7) can no longer rotate to the left, thereby making the left leg and the right leg reach the state of being together.
[0066] The working principle of this invention is as follows: When the left and right legs are together, an external force drives the right block 7 to rotate upward away from the left block 6. At this time, the right block 7 drives the right cover 5 to rotate relative to the right ball sleeve 31. During the rotation, the right ball sleeve 31 can adapt to the rotation by sliding on the right middle block 3. When the right edge 74 abuts against the right protrusion 51 and can no longer rotate upward, the right block 7 rotates to the top. At this time, the left block 6 is driven to rotate upward. The left block 6 drives the left cover 4 to rotate relative to the left ball sleeve 21. During the rotation, the left ball sleeve 21 can adapt to the rotation by sliding on the left middle block 2. When the left edge 64 abuts against the left protrusion 41 and can no longer rotate upward, the left block 6 rotates to the top. At this time, the left and right legs are in an extended state.
