Detailed Implementation

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] Combination Figures 1 to 3 According to an embodiment of the present invention, the limb component 100 of the assembly toy includes: an upper limb 10, a lower limb 20, and a joint 30. At least a portion of the joint 30 is disposed between the upper limb 10 and the lower limb 20, and the joint 30 is hinged to both the upper limb 10 and the lower limb 20. Specifically, the joint 30 can serve as a power hub for the movement of the upper limb 10 and the lower limb 20, facilitating the limb component 100 to perform flexion and extension movements. Exemplarily, the limb component 100 can be a limb structure used for the assembly toy to perform activities, support, or perform specific functions. For example, the assembly toy can be a humanoid toy, and the limb component 100 can be an arm or a leg. Taking the limb component 100 as an arm of a humanoid toy as an example, the upper limb 10 can be the upper arm, the lower limb 20 can be the forearm, and the joint 30 can be the elbow joint, through which the flexion and extension of the arm can be achieved.

[0031] Combination Figure 2 and Figure 3 The limb assembly 100 also includes a protective armor portion 40, which is connected to at least two of the upper limb portion 10, lower limb portion 20, and joint portion 30. Exemplarily, the protective armor portion 40 may be connected to the upper limb portion 10 and the joint portion 30; or, the protective armor portion 40 may be connected to the lower limb portion 20 and the joint portion 30; or, the protective armor portion 40 may be connected to the upper limb portion 10 and the lower limb portion 20; or the protective armor portion 40 may be connected to all three portions. The protective armor portion 40 is configured to unfold and retract with the limb assembly 100. Specifically, the limb assembly 100 can simultaneously unfold and retract the protective armor portion 40 during flexion and extension, enriching the form of the building toy and enhancing its fun.

[0032] Exemplarily, when the limb assembly 100 is extended, at least a portion of the armor portion 40 can be housed in the upper limb portion 10, and when the limb assembly 100 is bent, at least a portion of the armor portion 40 unfolds relative to the upper limb portion 10; or, when the limb assembly 100 is extended, at least a portion of the armor portion 40 can be housed in the lower limb portion 20, and when the limb assembly 100 is bent, the armor portion 40 unfolds relative to the lower limb portion 20; or, the armor portion 40 may include a first armor plate 41 and a second armor plate 42, combined with Figure 2 When the limb component 100 is extended, at least a portion of the first armor 41 can be stored in the upper limb 10, and at least a portion of the second armor 42 can be stored in the lower limb 20, in combination. Figure 3 When the limb component 100 bends, the first armor 41 can unfold relative to the upper limb 10, and the second armor 42 can unfold relative to the lower limb 20. This allows the limb component 100 to drive the armor 40 to unfold and retract in conjunction with the upper limb 10 and lower limb 20 as they rotate relative to each other, enriching the form of the building toy and enhancing its fun.

[0033] Combination Figure 3 and Figure 4 In some embodiments of this utility model, the armor part 40 includes a first armor 41, which is slidably connected to the upper limb part 10. Specifically, the first armor 41 can slide relative to the upper limb part 10, so that the first armor 41 can be unfolded and retracted when the upper limb part 10 rotates relative to the joint part 30.

[0034] In addition, the first armor 41 is slidably connected to the joint 30, which means that the first armor 41 can also slide relative to the joint 30, increasing the sense of movement of the first armor 41 and enhancing the fun of the assembly toy.

[0035] For example, when the upper limb 10 rotates relative to the joint 30, the first armor 41 can slide relative to the joint 30 first, and then slide relative to the upper limb 10; or, when the upper limb 10 rotates relative to the joint 30, the first armor 41 can slide relative to the upper limb 10 first, and then slide relative to the joint 30, so that the unfolding and folding of the first armor 41 has a certain sense of layering, further enhancing the fun of the assembly toy.

[0036] Combination Figure 4 In some embodiments of this utility model, the upper limb 10 includes a first slide rail 11, and the first armor 41 includes a first slider 411. The first slider 411 is slidably disposed on the first slide rail 11. The first slide rail 11 and the first slider 411 cooperate to guide the movement of the upper limb 10 and the first armor 41, which facilitates the unfolding and retraction of the first armor 41 relative to the upper limb 10, simplifies the structure of the limb assembly 100, and facilitates the assembly of the limb assembly 100.

[0037] Combination Figure 4 In some embodiments of this utility model, the joint portion 30 includes a second slide rail 31, and the first armor plate 41 includes a second slider 412, which is slidably disposed on the second slide rail 31. The second slide rail 31 and the second slider 412 cooperate to guide the movement of the joint portion 30 and the first armor plate 41, facilitating the sliding of the first armor plate 41 relative to the joint portion 30, simplifying the structure of the limb assembly 100, and facilitating the assembly of the limb assembly 100.

[0038] For example, the joint 30 includes a first hinge point 32 and a second hinge point 33, which are arranged at intervals. The first hinge point 32 is rotatably connected to the upper limb 10, and the second hinge point 33 is rotatably connected to the lower limb 20. The first slide rail 11 may be configured as an arcuate track extending around the first hinge point 32, and the second slide rail 31 may be configured as an arcuate track extending around the first hinge point 32.

[0039] Combination Figure 2 , Figures 5 to 7In some embodiments of this utility model, the limb assembly 100 has an unfolded state and a first folded state. In the unfolded state, the upper limb 10 and the lower limb 20 extend in opposite directions, and the angle between the upper limb 10 and the joint 30 is a1. In the first folded state, the angle between the upper limb 10 and the joint 30 is a2, where a1 > a2 and a1 - a2 ≤ 40°. In both the unfolded and first folded states, at least a portion of the first armor 41 is housed inside the upper limb 10. Specifically, when the limb assembly 100 is in the unfolded state, at least a portion of the first armor 41 is housed inside the upper limb 10. When the rotation angle of the upper limb 10 relative to the joint 30 is less than or equal to 40°, the first armor 41 remains housed inside the upper limb 10. That is, when the rotation angle of the upper limb 10 relative to the joint 30 is small, the first armor 41 will not unfold.

[0040] Combination Figure 5 and Figure 7 For example, the angle between the upper limb 10 and the joint 30 is defined as the angle between line segment A and line segment B. Line segment A is the line segment between the center point of the joint 30 near the end of the upper limb 10 and the center point of the joint 30 near the end of the lower limb 20. Line segment B is the line segment between the center point of the upper limb 10 away from the joint 30 and the center point of the end near the joint 30. In the unfolded state, the upper limb 10 and the lower limb 20 extend in opposite directions, and the angle between the upper limb 10 and the joint 30 can be approximately 178°. When the limb assembly 100 needs to switch to the first folded state, the upper limb 10 rotates at an angle less than or equal to 40° relative to the joint 30, and the first armor 41 will not unfold. Of course, in the unfolded state, the angle α1 between the upper limb 10 and the joint 30 can also be set to 180°, 177°, 176°, etc.

[0041] For example, the limb component 100 can be the arm of a humanoid toy. When the limb component 100 is unfolded, the arm can be straightened. The limb component 100 can be switched to the first folded state by rotating the upper limb part 10 relative to the joint part 30, which makes it easier for the assembled toy to achieve fine movements such as arm bending and enriches the play of the assembled toy.

[0042] Combination Figure 9 and Figure 10The limb assembly 100 also has a second folded state. In the second folded state, the angle between the upper limb 10 and the joint 30 is a3, where a1 > a3 and a1 - a2 > 40°. In the second folded state, the first armor 41 unfolds relative to the upper limb 10. Specifically, when the limb assembly 100 is in the unfolded state, at least a portion of the first armor 41 is tucked inside the upper limb 10. When the upper limb 10 rotates at an angle greater than 40° relative to the joint 30, the first armor 41 unfolds relative to the upper limb 10. That is, when the upper limb 10 rotates at a large angle relative to the joint 30, the first armor 41 unfolds. In combination with the foregoing, the first armor 41 does not unfold in the unfolded state and the first folded state. When the limb assembly 100 switches to the second folded state, the first armor 41 unfolds relative to the upper limb 10, making the movement of the first armor 41 more layered, further enriching the form of the building toy, and enhancing the fun of the building toy.

[0043] For example, the upper limb 10 includes a first slide rail 11, the first armor 41 includes a first slider 411 slidably disposed on the first slide rail 11, the joint 30 includes a second slide rail 31, the first armor 41 includes a second slider 412 slidably disposed on the second slide rail 31. The sliding resistance between the first slider 411 and the first slide rail 11 is greater than the sliding resistance between the second slider 412 and the second slide rail 31. This allows the second slider 412 to slide first on the second slide rail 31 when the upper limb 10 rotates around the first hinge point 32. When the second slider 412 slides to the limit position of the second slide rail 31, it then drives the first slider 411 to slide on the first slide rail 11. For example, when the limb assembly 100 is in the unfolded state, the first armor 41 is stored in the limb assembly 100. When the limb assembly 100 switches from the unfolded state to the first folded state, the second slider 412 slides within the second slide rail 31, and the first armor 41 does not unfold in conjunction. When the limb assembly 100 continues to switch from the first folded state to the second folded state, the first slider 411 slides within the first slide rail 11, causing the first armor 41 to unfold relative to the upper limb 10. In other words, when the limb assembly 100 is in the straightened state, the first armor 41 is stored in the limb assembly 100. When the limb assembly 100 is bent at a small angle, the first armor 41 does not unfold. When the limb assembly 100 is bent at a large angle, the first armor 41 unfolds, making the movement of the first armor 41 more layered and enriching the fun of the assembly toy.

[0044] Combination Figure 3 and Figure 5In some embodiments of this utility model, the armor portion 40 further includes a second armor 42, which connects the lower limb portion 20 and the joint portion 30. In the unfolded state, one end of the first armor 41 is tucked inside the upper limb portion 10, and the other end of the first armor 41 is tucked inside the second armor 42. By providing the first armor 41 and the second armor 42, the shape of the limb assembly 100 is further enriched. In the unfolded state, the other end of the first armor 41 is tucked inside the second armor 42, making the structure of the limb assembly 100 compact in the unfolded state and preventing the first armor 41 from being exposed.

[0045] Combination Figure 3 and Figure 4 In some embodiments of this utility model, the armor portion 40 includes a second armor 42, which is slidably connected to the lower limb portion 20 and hinged to the joint portion 30. Specifically, the second armor 42 can slide relative to the lower limb portion 20, facilitating the unfolding and retraction of the second armor 42 when the lower limb portion 20 rotates relative to the joint portion 30, enriching the form of the building toy and enhancing its fun.

[0046] Combination Figure 4 Furthermore, the lower limb 20 includes a third slide rail 21, and the second armor 42 includes a third slider 421, which is slidably disposed on the third slide rail 21. The third slide rail 21 and the third slider 421 cooperate to guide the movement of the lower limb 20 and the second armor 42, facilitating the unfolding and retraction of the second armor 42 relative to the lower limb 20, simplifying the structure of the limb assembly 100, and facilitating the assembly of the limb assembly 100.

[0047] Combination Figure 2 , Figure 3 , Figure 10 and Figure 11 In some embodiments of this utility model, the limb assembly 100 has an unfolded state and a third folded state. In the unfolded state, the upper limb 10 and the lower limb 20 extend in opposite directions, and the angle between the lower limb 20 and the joint 30 is a4. At least a portion of the second armor 42 is folded inside the lower limb 20. In the third folded state, the angle between the lower limb 20 and the joint 30 is a5, where a4 > a5, and the second armor 42 is unfolded relative to the lower limb 20. Specifically, when the limb assembly 100 is in the unfolded state, at least a portion of the second armor 42 is housed inside the lower limb 20. When the lower limb 20 rotates relative to the joint 30, the second armor 42 unfolds relative to the lower limb 20.

[0048] For example, the angle between the lower limb portion 20 and the joint portion 30 is defined as the angle between line segment A and line segment C. Line segment A is the line segment between the center point of the joint portion 30 near the end closest to the upper limb portion 10 and the center point of the joint portion 30 near the end closest to the lower limb portion 20. Line segment C is the line segment between the center point of the lower limb portion 20 away from the joint portion 30 and the center point of the lower limb portion 20 near the joint portion 30. For example, in the unfolded state, the upper limb portion 10 and the lower limb portion 20 extend in opposite directions. a4 can be 175°, and a5 can be 160°, 150°, 140°, 120°, etc. Of course, in the unfolded state, the angle a4 between the lower limb portion 20 and the joint portion 30 can also be set to 180°, 177°, 176°, etc.

[0049] Combination Figure 5 In some embodiments of this utility model, the joint portion 30 includes a first hinge point 32 and a second hinge point 33, which are arranged at intervals. The first hinge point 32 is rotatably connected to the upper limb portion 10, and the second hinge point 33 is rotatably connected to the lower limb portion 20. By providing the first hinge point 32 and the second hinge point 33 arranged at intervals on the joint connection portion, the flexion and extension of the limb assembly 100 is facilitated, and the exposure of the joint connection portion of the limb assembly 100 during flexion and extension is reduced, thereby improving the realism of the assembled toy.

[0050] Combination Figures 1 to 11In some specific embodiments of this utility model, the limb component 100 includes: an upper limb 10, a lower limb 20, a joint 30, and a protective armor 40. At least a portion of the joint 30 is disposed between the upper limb 10 and the lower limb 20. The joint 30 includes a first hinge point 32 and a second hinge point 33 arranged at intervals. The first hinge point 32 is rotatably connected to the upper limb 10, and the second hinge point 33 is rotatably connected to the lower limb 20. The protective armor 40 includes a first armor 41 and a second armor 42. The first armor 41 is slidably connected to the upper limb 10 and is slidably connected to the joint 30. The second armor 42 is slidably connected to the lower limb 20 and is hinged to the joint 30. When the upper limb 10 rotates relative to the joint 30 around the first hinge point 32, it can cause the first armor 41 to unfold and retract in conjunction. When the lower limb 20 rotates relative to the joint 30 around the second hinge point 33, it can cause the second armor 42 to unfold and retract in conjunction. When the upper limb 10 and lower limb 20 are in the unfolded (extended) state, at least a portion of the first armor 41 can be retracted into the upper limb 10, and at least a portion of the second armor 42 can be retracted into the lower limb 20, making the structure of the limb assembly 100 compact. The transition from the unfolded state to the folded state means that when the limb component 100 is bent, if the rotation angle of the upper limb 10 relative to the joint 30 is less than or equal to 40°, the first armor 41 will not be pulled. If the rotation angle of the upper limb 10 relative to the joint 30 is greater than 40°, the first armor 41 will be pulled to unfold. When the lower limb 20 rotates relative to the joint 30, the second armor 42 can be pulled to unfold. This makes the unfolding of the armor 40 more layered, enriches the shape of the limb component 100, and enhances the fun of the assembly toy.

[0051] This utility model also proposes an assembly toy, including the aforementioned limb component 100.

[0052] The assembly toy may include a main body and the aforementioned limb components 100, with the limb components 100 connected to the main body. For example, the main body and limb components 100 may include multiple parts, which are assembled and combined to create the toy's shape. By incorporating the aforementioned limb components 100, the upper limbs 10 and lower limbs 20 of the limb components 100 can, when rotated relative to each other, cause the armor parts 40 to unfold and retract in tandem, enriching the form of the assembly toy and enhancing its fun factor.
