DETAILED DESCRIPTION

[0040] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0041] Combination Figures 1 to 9 According to the shoulder joint 10 of the assembly toy 1000 of the embodiment of the present invention, the assembly toy 1000 includes a main body 100 and a limb 200, and the shoulder joint 10 includes: a first connection part 11, a second connection part 12 and a third connection part 13, the first connection part 11 is used to connect the main body 100; the second connection part 12 is connected to the first connection part 11, and the second connection part 12 is used to connect the limb 200; the third connection part 13 is connected to the second connection part 12, and the third connection part 13 is used to connect the shoulder accessory 25. Specifically, the first connection part 11 and the second connection part 12 can realize the connection between the limb 200 and the main body 100, and the third connection part 13 can realize the connection of the shoulder accessory 25, thereby, the assembly of the three parts of the toy can be realized through a shoulder joint 10 connector, which is conducive to simplifying the assembly structure and improving playability. More specifically, the third connection portion 13 provided at the shoulder joint 10 can also improve the flexibility of the shoulder accessory 25 after assembly. When the shoulder joint 10 rotates, the limb 200 and the shoulder accessory 25 can both rotate, thereby helping to improve the simulation of the toy and enhance the experience of children when playing with the toy.

[0042] According to the shoulder joint 10 of the assembly toy 1000 according to the embodiment of the present invention, multiple connecting parts are provided so that multiple assembly parts can be connected to the shoulder joint 10, which is convenient for users to assemble. After assembly, the limb 200 and the shoulder accessories 25 can move with the shoulder joint 10, which can improve the flexibility of the accessories of various parts of the toy during movement and help improve the simulation of the toy.

[0043] Specifically, in the related art, shoulder accessories need to be installed separately on the limbs, and during assembly, the connectors of the shoulder accessories need to be installed separately, and then the shoulder accessories are installed. The assembly operation is relatively complicated, which causes children to lose patience or find it difficult to complete the assembly. In addition, there are many delicate parts, which is not conducive to children's management of accessories. In addition, the shoulder accessories connected to the limbs are fixed on the limbs and cannot move with the movement of the shoulder joints, resulting in poor flexibility and low simulation of the toy. In the present application, the shoulder joint 10 is provided with a plurality of connecting parts, thereby, a plurality of connectors used to connect between a plurality of components can be integrated together, so that when assembling a plurality of components, only one accessory is needed to achieve assembly, and when the shoulder joint 10 rotates, a plurality of components can move, which is conducive to improving the simulation of the toy, thereby increasing the fun of children and improving playability.

[0044] Combination Figure 1 and Figure 2 In some embodiments of the present invention, the shoulder joint 10 further includes a first connecting rod 14 and a second connecting rod 15, wherein the first connecting rod 14 is connected between the first connecting portion 11 and the second connecting portion 12, and the second connecting rod 15 is connected between the second connecting portion 12 and the third connecting portion 13. Specifically, the first connecting rod 14 can realize the spaced connection between the first connecting portion 11 and the second connecting portion 12, so that there is a spacing between the first connecting portion 11 and the second connecting portion 12, and the spacing can increase the activity space after the main body 100 is connected to the limb 200, avoid interference between the limb 200 and the main body 100 when the limb 200 moves, and improve the activity of the toy. Similarly, the second connecting rod 15 can realize the spaced connection between the second connecting portion 12 and the third connecting portion 13, so that the shoulder accessory 25 has an activity space, avoid interference between the shoulder accessory 25 and the shoulder 20 or the limb 200, and affect the activity of the shoulder accessory 25.

[0045] In some embodiments of the present invention, Figure 1 and Figure 2For example, in some monster-shaped dolls or female dolls with high flexibility, the first connecting rod portion 14 and the second connecting rod portion 15 have an angle. Due to the particularity of the doll setting, the shoulder joint and the arm joint require a larger movable angle. Therefore, the angle range between the first connecting rod portion 14 and the second connecting rod portion 15 is required to be larger, and the angle is not less than 90° and not more than 170°. Therefore, the relationship between the first connecting portion 11, the second connecting portion 12 and the third connecting portion 13 can be defined, so that the third connecting portion 13 has a suitable movable space to avoid interference with the movement of the shoulder accessory 25 after installation, thereby facilitating the improvement of the simulation degree.

[0046] In most male character dolls and human-shaped dolls, the shoulder joint structure with an angle of not less than 90° and not more than 150° can meet the movable requirements in most cases, so that the shoulder accessory 25 can move in the area obliquely above the shoulder 20, improving the aesthetics and authenticity. At the same time, the three-connection structure of the integrated structure also makes the coordination of the shoulder joint with other joints more natural, and the overall look and feel will be more natural in the multi-angle movement and various postures of the doll, greatly improving the simulation of the doll. Specifically, in actual application, the assembly toy 1000 can be a human-shaped toy, or an animal-shaped toy or an anthropomorphic animal-shaped toy. Therefore, the position of the shoulder accessory 25 can be set according to actual use needs. When the angle is large, the third connection part 13 deviates from the first connection part 11 to a large extent. In this way, the third connection part 13 can be connected to a larger shoulder accessory 25, or when the assembly toy 1000 is a monster or an anthropomorphic animal image, the flexibility of assembly and the diversity of toy shapes can be improved.

[0047] Optionally, when the second connection portion 12 is in the shape of a ring, a pancake or a sphere, the third connection portion 13 is disposed between the highest point and the lowest point of the second connection portion 12 along the up-down direction.

[0048] Optionally, the building block toy 1000 may have a plurality of shoulder joint 10 components, and the plurality of shoulder joint 10 components may be in the form of different angles between the first connecting rod portion 14 and the second connecting rod portion 15. When children play with the building block toy 1000, they may select a suitable shoulder joint 10 to assemble according to the scene and image, thereby increasing the fun of the building block toy 1000.

[0049] In some embodiments of the present invention, the second connecting rod portion 15 has a first end connected to the second connecting portion 12 and a second end connected to the third connecting portion 13. The cross-sectional area of ​​the first end of the second connecting rod portion 15 is larger than the cross-sectional area of ​​the second end of the second connecting rod portion 15, which can provide assembly space for the shoulder accessory 25 and help improve the connection stability. Specifically, the second connecting portion 12 is used to connect the limb 200. Since the size of the limb 200 is large, the size of the second connecting portion 12 is also large. The size of the shoulder accessory 25 connected to the third connecting portion 13 is small, so the size of the third connecting portion 13 can be smaller than the first connecting portion 11 or the second connecting portion 12. The second connecting rod portion 15 is configured such that the first end connected to the second connecting portion 12 with a larger size is thicker and the second end connected to the third connecting portion 13 is thinner, which can improve the mobility while improving the structural stability.

[0050] Combination Figure 1 and Figure 2 In some embodiments of the present invention, the spacing between the first connecting portion 11 and the second connecting portion 12 is x, and the height of the assembly toy is h, wherein x satisfies x≤0.0125h+6. Specifically, in the human aesthetics model, when the width of the human shoulder 20 is one-fourth of the human height and the human torso is one-fifth of the human height, the shape is closest to the shape of the ideal human body, which will naturally leave a beautiful visual impression on people. Therefore, according to the human aesthetics model, the width of the two shoulders 20 is 0.25h of the human shoulder width minus 0.2h of the human torso width = 0.05h, and the width of the single shoulder is 0.025h. If the distance between the first connection part 11 and the second connection part 12 is x, and the length of the first connecting rod part 14 is b, it can be obtained that 0.025h-(xb)≥x, wherein b is a constant. According to the inventor's long-term experiments, it is found that the distance x between the first connection part 11 and the second connection part 12 is positively correlated with the ball head diameter of the first connection part 11. The larger the ball head diameter, the larger the distance x. If it is assumed that the ball head diameter is L, then x=L+b. It is found in long-term calculations that the functional relationship holds when b is 12. Therefore, b in the embodiment of the present invention is 12 mm. Therefore, by simplifying the formula, it can be obtained that x≤0.0125h+6.

[0051] Therefore, when the height of the assembled toy 1000 is 90 mm, x≤7.125 mm; when the height of the assembled toy 1000 is 100 mm, x≤7.25 mm; when the height of the assembled toy 1000 is 120 mm, x≤7.5 mm; when the height of the assembled toy 1000 is 150 mm, x≤7.875 mm.

[0052] Furthermore, there is also a spacing between the second connecting portion 12 and the third connecting portion 13, the spacing is x, and the height of the assembled toy is h. The calculation method is the same as mentioned above and will not be repeated again. Among them, b can be the length of the second connecting rod portion 12, and can also be set to 12 mm. Therefore, the formula is obtained, and x satisfies x≤0.0125h+6.

[0053] This functional relationship shows that the different distances between the three connecting parts of the shoulder joint 10 are mainly due to the corresponding changes in the design of the shoulder ball head size in toys of different sizes, and then the distances between the three connecting parts will also change accordingly, so as to adapt to the shoulder accessories in the process of assembling the arm movement of the toy 1000 to be more natural, and there will be no interference between the various parts, thereby improving the playability and controllability of the toy.

[0054] More specifically, in some embodiments of the present invention, the first connection portion 11 and the second connection portion 12 are spaced apart, and the spacing between the first connection portion 11 and the second connection portion 12 is set to be no less than 3 mm and no more than 8 mm; the second connection portion 12 and the third connection portion 13 are spaced apart, and the spacing between the second connection portion 12 and the third connection portion 13 is set to be no less than 3 mm and no more than 8 mm. Combined with the above, this spacing can provide a space for the shoulder accessory 25, the limb 200 or the main body 100 to move, so as to avoid interference in the movement of these components after they are connected to the shoulder joint 10.

[0055] For example, the spacing between the first connection part 11 and the second connection part 12 can be 4 mm, and the spacing between the second connection part 12 and the third connection part 13 can be 5 mm; or, the spacing between the first connection part 11 and the second connection part 12 can be 6 mm, and the spacing between the second connection part 12 and the third connection part 13 can be 6 mm. That is to say, according to the form of different toys, the spacing between the first connection part 11 and the second connection part 12 and the spacing between the second connection part 12 and the third connection part 13 can be different or the same. The value of the spacing can be based on the size of the assembly toy 1000. For example, when the assembly toy 1000 is larger, the spacing is larger, such as 8 mm, and when the assembly toy 1000 is smaller, the spacing is smaller, such as 4 mm. Or the distance of the spacing can be reasonably selected according to the form of the toy or the overall aesthetics.

[0056] Combination Figure 1 and Figure 2 In some embodiments of the present invention, at least one of the first connection part 11, the second connection part 12 and the third connection part 13 is configured as a universal joint to achieve a rotational connection, thereby improving the mobility of the assembly toy 1000 and facilitating manual disassembly and assembly by users without the need for tools.

[0057] Specifically, combined Figure 2 and Fig. 9In some embodiments of the present invention, the second connecting portion 12 is in the shape of a ball head, and the limb 200 is configured with a ball head seat. The limb 200 can be detachably sleeved on the second connecting portion 12, so that the limb 200 can be rotatably connected to the main body 100 and is easy to disassemble and assemble.

[0058] In other embodiments of the present invention, Figure 1 and Figure 6 The second connection part 12 is in the shape of a round pancake, and the limb 200 is configured with a mounting seat 201. The second connection part 12 can be detachably inserted into the mounting seat 201, so that the limb 200 can be rotatably connected to the main body 100 and is easy to disassemble. More specifically, the second connection part 12 is in the shape of a round pancake or annular ring with a certain thickness. The circumference of the second connection part 12 can connect the first connecting rod part 14 or the first connecting part 11 and the second connecting rod part 15 or the third connecting part 13. The upper surface and the lower surface of the second connection part 12 are in contact or abutment with the inner wall of the mounting seat 201, which can improve the stability of the second connection part 12 after being connected to the limb 200.

[0059] Furthermore, in some embodiments of the present invention, the first connection part 11 is interference-fitted with the main body 100, the second connection part 12 is interference-fitted with the limb 200, and the third connection part 13 is interference-fitted with the shoulder accessory 25. Thus, it is easy to realize the connection between the first connection part 11 and the main body 100, the connection between the second connection part 12 and the limb 200, and the connection between the third connection part 13 and the shoulder 20, and it is possible to realize the detachable connection between the connector and the component. In addition, the interference-fit connection method makes the connection between the connector and the component have a certain stability and is not easy to shake. In this way, when the user plays with the toy, the limb 200 may be rotated to a certain angle, and the interference-fit connection method can position the adjusted limb 200 at the adjustment position, so that the toy can be changed into various shapes, the playability is improved, and the structure is simple and easy to manufacture.

[0060] Combination Figure 1 and Fig. 9 The assembly toy 1000 according to an embodiment of the present invention comprises: a main body 100, a limb 200, a shoulder accessory 25 and the shoulder joint 10 of the aforementioned assembly toy 1000, a first connection part 11 connecting the main body 100, a second connection part 12 connecting the limb 200, and a third connection part 13 connecting the shoulder accessory 25.

[0061] According to the assembly toy 1000 of the embodiment of the present invention, by applying the aforementioned shoulder joint 10 in the assembly toy 1000, the main body 100, the limbs 200 and the shoulder accessories 25 can be connected through the shoulder joint 10, which is convenient for users to assemble and after assembly, the limbs 200 and the shoulder accessories 25 can move with the shoulder joint 10, which can improve the flexibility of the accessories of various parts of the toy during movement, and is conducive to improving the simulation of the toy.

[0062] Specifically, combined Figure 4 In some embodiments of the present invention, the main body 100 is provided with a first hinge seat 110, the first hinge seat 110 is provided with a first accommodating space, and the first connecting portion 11 is passed through the first accommodating space and is rotatably connected to the first hinge seat 110. Specifically, the first accommodating space can accommodate the first connecting portion 11 and the first connecting portion 11 can rotate in the first accommodating space, so that the first connecting portion 11 and the main body 100 can be stably connected, and the first connecting portion 11 and the main body 100 can rotate relatively, thereby improving the playability of the assembly toy 1000.

[0063] Combination Figure 3 In some embodiments of the present invention, the limb 200 includes a shoulder 20, the shoulder 20 is provided with a second hinge seat 22, the second hinge seat 22 is provided with a second accommodating space, the second connecting portion 12 is passed through the second accommodating space and is rotatably connected to the second hinge seat 22, the second accommodating space can accommodate the second connecting portion 12 and the second connecting portion 12 can rotate in the second accommodating space, a stable connection between the second connecting portion 12 and the shoulder 20 can be achieved, and the second connecting portion 12 and the shoulder 20 can rotate relative to each other, thereby improving the playability of the assembly toy 1000.

[0064] More specifically, combined with Figure 3 and Figure 4 The second hinge seat 22 has a first opening 202 and a second opening 203. The first opening 202 is connected to the second accommodation space. The first connecting rod 14 between the first connecting part 11 and the second connecting part 12 is movably arranged in the first opening 202, so that one end of the first connecting rod 14 extends out of the second accommodation space, which is convenient for the first connecting part 11 to be connected to the main body 100. The second opening 203 is connected to the second accommodation space. The second connecting rod 15 between the second connecting part 12 and the third connecting part 13 is movably arranged in the second opening 203, so that one end of the second connecting rod 15 extends out of the second accommodation space, which is convenient for the third connecting part 13 to be connected to the main body 100.

[0065] Further, in some embodiments of the present invention, the first opening 202 includes a first sub-opening 202a and a second sub-opening 202b connected along a first direction, and the second sub-opening 202b has a larger opening size along a second direction than the first sub-opening 202a, wherein the first direction is perpendicular to the second direction.

[0066] The first direction can refer to Figure 7 The up and down directions in the second direction can refer to Figure 6 In the front-to-back direction, that is to say, the first opening 202 allows the first connecting rod portion 14 to pass through the second hinge seat 22, and the first sub-opening 202a and the second sub-opening 202b can also provide activity space for the first connecting rod portion 14. When the second connecting portion 12 rotates in the second hinge seat 22, the larger second sub-opening 202b can allow the second connecting rod portion 15 to swing up and down and forward and backward. The size of the second sub-opening 202b along the front-to-back direction is reduced, so that when in the extreme position, the swing of the first connecting rod portion 14 along the front-to-back direction can be limited, which is beneficial to improve the stability of the assembly toy 1000 during activity.

[0067] The second opening 203 includes a third sub-opening 203a, a fourth sub-opening 203b and a fifth sub-opening 203c which are interconnected along the first direction, the fourth sub-opening 203b is arranged between the third sub-opening 203a and the fifth sub-opening 203c, and the opening size of the fourth sub-opening 203b along the second direction is larger than the third sub-opening 203a and the fifth sub-opening 203c, wherein the first direction is perpendicular to the second direction. Specifically, the second connecting rod portion 15 has a larger range of motion at the fourth sub-opening 203b, which is conducive to improving the degree of mobility. When the second connecting rod portion 15 moves upward to the first extreme position, the movement of the second connecting rod portion 15 in the front-to-back direction is subject to certain restrictions, which can improve the stability of the position adjustment of the shoulder accessory 25. Similarly, when the second connecting rod portion 15 moves downward to the second extreme position, the second connecting rod portion 15 can also move along a predetermined direction, which is convenient for user adjustment and provides feedback on the user's hand feel, thereby improving the interactivity of the toy. In other words, combined with Figure 4 The second opening 203 can be constructed in a form that is wide in the middle and narrow at both ends along the up-down direction, which can improve the mobility of the connecting rod 11 while limiting the position at the extreme positions at both ends to improve the stability during activity.

[0068] Combination Figure 6In some other embodiments of the present invention, the shoulder 20 is provided with a second hinge seat 22, the second hinge seat 22 is provided with a second accommodating space, the second connecting portion 12 is penetrated in the second accommodating space, the second connecting portion 12 is penetrated in the second accommodating space, and is rotatably connected with the second hinge seat 22, the second hinge seat 22 has a third opening 204, the third opening 204 is connected to the second accommodating space, the first connecting rod portion 14 between the first connecting portion 11 and the second connecting portion 12 and the second connecting rod portion 15 between the second connecting portion 12 and the third connecting portion 13 are movably penetrated in the third opening 204, so that after the second connecting portion 12 is installed on the second hinge seat 22, the first connecting rod portion 14 and the second connecting rod portion 15 can extend outward to connect other components, and the third opening 204 extends along an arc from a side close to the main body 100 to the outside of the limb 200 away from the main body 100, thereby increasing the activity space of the first connecting rod portion 14 and the second connecting rod portion 15. More specifically, the second hinge seat 22 is also provided with a transition section 24, and the transition section 24 is provided at the opposite ends of the third opening 204 along the left and right directions. When the first connecting rod portion 14 and the second connecting rod portion 15 are rotated to the extreme position along the third opening 204, the transition section 24 can cooperate with the first connecting rod portion 14 and the second connecting rod portion 15. The first connecting rod portion 14 and the second connecting rod portion 15 can fit the transition section 24 to position the connecting rod 11 to the extreme position, and can also protect the connecting rod 11 to prevent children from damaging the connecting rod 11 due to excessive rotation force during operation.

[0069] Combination Fig. 9 In some embodiments of the present invention, the shoulder accessory 25 is provided with a third accommodating space, the third connecting portion 13 is inserted into or inserted into the third accommodating space, and is rotatably connected to the shoulder accessory 25, so that the assembly of the shoulder accessory 25 can be realized, and when the second connecting portion 12 is spherical, the shoulder accessory 25 can also rotate independently, thereby further increasing the movable parts of the toy, improving the playability and simulation.

[0070] Specific, combined Figures 5 and 6 In some embodiments of the present invention, the limb 200 includes an arm 30 and a leg 60, wherein the arm 30 includes an upper arm 31 and a lower arm 32, wherein the upper arm 31 is hinged to the lower arm 32, and the lower arm 32 is provided with a first connecting portion 33 and a second connecting portion 34 at opposite ends in the up and down directions, and the first connecting portion 33 is eccentrically connected to the lower arm 32, so that the upper arm 31 can be closer to the lower arm 32 when rotating, and the lower arm 32 has a larger rotation angle, which makes the movement between the limbs more realistic and closer to the state of the human body moving the limbs.

[0071] The first connection part 33 is used for articulating the upper arm 31, and the second connection part 34 is used for connecting the hand 35. The first connection part 32 is a mounting seat with a matching hole, and the second connection part 36 is a ball head. The arm mecha 34 can also be set on the outside of the lower arm 32. Figure 8 The outer periphery of the arm mecha 34 can also be covered with an arm armor 37.

[0072] Combination Figure 6 and Figure 8 In some embodiments of the present invention, the shoulder 20 is provided with a connecting column 21, and the upper arm 31 is provided with a matching hole, and the connecting column 21 extends into the matching hole and can rotate relative to the connecting column 21. Specifically, after the upper arm 31 is installed, the upper arm 31 can be rotated relative to the shoulder 20 through the second connecting portion 12, for example, it can be rotated upward, forward, left or right to achieve the action of lifting the upper arm 31, and the upper arm 31 can also achieve circumferential rotation to achieve the action of flipping the upper arm 31, thereby further improving the simulation degree.

[0073] More specifically, combined Figures 5 and 6 In some embodiments of the present invention, the leg 60 includes a thigh 61 and a calf 62, wherein the thigh 61 is hinged to the calf 62, and the calf 62 is provided with a first connection portion 63 and a second connection portion 64 at opposite ends in the up-down direction, and the third connection portion 63 is eccentrically connected to the calf 62, and the third connection portion 63 is used for the hinge connection of the thigh 61, and the fourth connection portion 66 is used for connecting the foot 65. The third connection portion 63 is a mounting seat with a matching hole, and the fourth connection portion 66 is a ball head. The leg mecha 64 can also be set on the outside of the calf 62. In combination with Figure 8 The outer periphery of the leg mecha 64 can also be covered with a leg armor 68.

[0074] The forearm 32 or the calf 62 extends along a first direction, the first connection portion 33 or the third connection portion 63 connects the forearm 32 or the calf 62, and extends along a second direction, the second direction is perpendicular to the rotation axis between the first connection portion 33 or the third connection portion 63 and the connection portion of the upper arm 31 or the thigh 61, and has an angle with the first direction. The angle is greater than 0 and less than or equal to 60 degrees.

[0075] The distance between the rotation axis of the forearm 32 or the calf 62 along the first direction and the perpendicular line of the rotation axis between the first connection part 33 or the third connection part 63 and the connection part of the upper arm 31 or the thigh 61 is greater than 0 and less than or equal to 5 mm.

[0076] Combination Figure 5In some embodiments of the present invention, the assembly toy further includes a waist component 50, including: a hip joint 51 and a connection seat 52, the hip joint 51 includes a frame, a first hinge part and a second hinge part, the first hinge part and the second hinge part are connected to the frame, and the first hinge part is used to connect the leg 60; the connection seat 52 includes a third hinge part 521 and a fourth hinge part 522 distributed up and down, the third hinge part 521 is rotatably connected to the second hinge part, and the fourth hinge part 522 is used to be rotatably connected to the main body 100. Specifically, the hip joint 51 includes a frame for connecting the first hinge part and the second hinge part, so that the frame can support the hinge part and can also position the first hinge part and the second hinge part to a predetermined position. During assembly, the first hinge part of the hip joint 51 is rotatably connected to the leg 60, the second hinge part is rotatably connected to the third hinge part 521 of the connection seat 52, and the third hinge of the connection seat 52 is rotatably connected to the main body 100. Thus, the connecting seat 52 is connected between the main body 100 and the hip joint 51, realizing the connection between the upper and lower parts of the building block toy 1000, and the connecting seat 52 and the main body 100, the connecting seat 52 and the hip joint 51, and the hip joint 51 and the leg 60 can all be rotated, making the movement of the middle waist position of the building block toy 1000 more flexible and the action simulation of the building block toy 1000 higher.

[0077] In some embodiments of the present invention, the rotation angle of the connecting seat 52 relative to the hip joint 51 is not less than 3 degrees and not more than 20 degrees. The appropriate rotation angle increases the range of motion of the waist and avoids interference between components during rotation.

[0078] The waist component 50 also includes a waist protection shell 53 and a hip joint protection shell 54. The waist protection shell 53 is sleeved on the outside of the connecting seat 52 and fixedly connected to the fixing member, thereby realizing the connection between the waist protection shell 53 and the connecting seat 52. Specifically, the connecting seat 52 includes a first fixing member and a second fixing member, and the first fixing member and the second fixing member are arranged on both sides of the connecting seat 52 along the left-right direction, which can improve the connection stability. The hip joint protection shell 54 is sleeved on the outside of the hip joint 51, and the hip joint 51 can be installed in the hip joint protection shell 54 to play a protective role, and can also cover the hip joint 51 to improve the aesthetics. The waist mecha can also be equipped to provide a variety of assembly forms and gameplay to improve playability.

[0079] More specifically, one of the second hinge part and the third hinge part 521 is a ball head and the other is a ball head seat, so that the connection seat 52 and the hip joint 51 can be universally rotated, which is beneficial to increase the rotation range and enable the robot to perform a variety of actions, such as the main body 100 flexing forward, lying backward, or tilting to the left and right sides. In addition, the matching method of the ball head and the ball head seat is relatively simple and easy to assemble.

[0080] When one of the third hinge 521 or the second hinge is a universal ball head, when the rotation angle is moderate, the diameter of the ball head can be appropriately increased to increase the bearing capacity of the connection and improve the structural strength. In other words, a relatively balanced value can be selected between the ball head diameter and the waist rotation degree, which can improve the mobility while maintaining the durability of the toy.

[0081] The following further describes how to design the diameter of the ball head. The diameter of the ball head of the fourth hinge 522 is x, and the height of the assembly toy 1000 is h, where x satisfies x≥(0.125h-7) / 2.3. Specifically, x≥(0.125h-7) / 2.3 is converted or simplified from x≥(0.125h-7-0.3x) / 2, and the converted formula can be easily incorporated into calculations during manufacturing.

[0082] The formula is described in detail below. According to the human body structure ratio of eight heads of the human body aesthetic model, the height of the entire body is divided into the length of eight heads. 0.125h is the length of one head. The height of the hinge portion of the connection seat 52 generally occupies the length of one head, so it is 0.125h. Taking the embodiment in which the third hinge portion 521 and the fourth hinge portion 522 of the connection seat 52 are connected by two ball heads arranged in the vertical direction as an example, 7 mm is the middle wall thickness between the third hinge portion 521 and the fourth hinge portion 522. 0.3x is the length of the connecting column 21 between the ball head and the middle wall thickness, which is 0.15x. For the upper and lower ball heads of the connecting seat 52, the sum of two 0.15x is 0.3x. The length of one head is 0.125h minus the middle wall thickness of 7 mm. After deducting the length of the connecting column 21 connecting the two ball heads at the upper and lower ends, 0.3x, it is equal to the diameter of the two ball heads. Therefore, the difference (0.125h-7-0.3x) needs to be divided by 2 to obtain the formula x≥(0.125h-7-0.3x) / 2. Substituting the height h into the formula, in the 90 mm building block toy 1000, the ball head diameter x must be greater than or equal to 1.85 mm; in the 100 mm building block toy 1000, the ball head diameter x must be greater than or equal to 2.39 mm; in the 120 mm building block toy 1000, the ball head diameter x must be greater than or equal to 3.48 mm; in the 150 mm building block toy 1000, the ball head diameter x must be greater than or equal to 5.11 mm (the above calculated values ​​have been rounded off).

[0083] It should be noted that when the components of the assembly toy 1000 are not suitable for matching according to the above formula, they can also be appropriately adjusted according to actual conditions. For example, when the toy is a humanoid robot, its structure may be different from the human body structure. The robot can be partially designed based on the human form. At this time, the size of the components and the size of the ball head seat that can be set on the components can be referred to for adjustment to achieve better activity effects.

[0084] In some embodiments of the present invention, the diameter of the ball head is no greater than 8 mm. Specifically, when the toy is in an animal form or other forms, the diameter of the ball head can also be set to a size no greater than 8 mm, so that the range of rotation can be increased while ensuring the bearing capacity. For example, when the height of the toy is small, the diameter of the ball head can be appropriately reduced to match the parts of the toy, or, when the size of a certain part of the toy is unconventional, the size of the ball head can be appropriately adjusted according to the size of the part, and the present invention is not limited thereto.

[0085] Optionally, the multiple ball heads of the waist component 50 can have the same diameter, which can be calculated according to the above formula, or can be set to have a ball head diameter of no more than 8 mm, and the diameters of the multiple ball heads can also be different.

[0086] In some embodiments of the present invention, one of the third hinge part 521 and the fourth hinge part 522 is a ball head, and the other is a ball head seat, which can achieve a foolproof effect while facilitating the connection with the hip joint 51 and the main body 100. Specifically, since the third hinge part 521 and the fourth hinge part 522 are respectively arranged on opposite sides of the connecting seat 52, the two hinge parts are arranged in different forms, which can be convenient for children to distinguish during assembly, so as to avoid the situation where the third hinge part 521 and the fourth hinge part 522 are installed reversely. For example, the third hinge part 521 is a ball head seat, and when assembling, the child can directly and quickly confirm that the third hinge part 521 in the form of a ball head seat should be connected to the ball head-shaped structure of the second hinge part by observing that the second hinge part is a ball head.

[0087] Of course, the third hinge part 521 and the fourth hinge part 522 may both be ball heads, or the third hinge part 521 and the fourth hinge part 522 may both be ball head seats.
