Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of a person skilled in the art, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection required by the present application.
[0033] For example, Figures 1-7As shown in the figure, an embodiment of this utility model discloses a shoulder structure for a humanoid model toy, which includes a torso joint 3, a first joint 4, a second joint 5, and an arm joint 6. One end 31 of the torso joint is used to connect to the torso 1 of the humanoid model toy; for example, one end 31 of the torso joint can be rotatably connected to the torso 1 to drive the arm 2 to be raised or lowered. The other end 32 of the torso joint is hinged to one end 41 of the first joint, the other end 42 of the first joint is hinged to one end 51 of the second joint, and the other end 52 of the second joint is hinged to one end of the arm joint 6. The other end of the arm joint 6 is used to connect to the arm 2 of the humanoid model toy; for example, the other end of the arm joint 6 can be fixedly connected to the arm 2.
[0034] The shoulder structure of the humanoid model toy has both a retracted and an extended state. In the retracted state, as... Figure 4 As shown, the other end 52 of the second joint is relatively close to the trunk joint 3. In the extended state, as... Figure 6 As shown, the other end 52 of the second joint is relatively far from the torso joint 3. When the shoulder structure of the humanoid model toy is in the extended state, as... Figure 7 As shown, the aforementioned arm joint 6 can rotate relative to the other end 52 of the second joint, so as to move the arm 2 closer to or away from the chest of the torso 1.
[0035] Compared to the existing technology where the torso joint 3 is directly hinged to the arm joint 6, the shoulder structure of this utility model adds a first joint 4 and a second joint 5. Thus, when the shoulder structure is in the extended state, the arm joint 6 is moved away from the torso 1, thereby reducing the interference of the torso 1 on the rotation of the arm joint 6, increasing the range of motion of the arm joint 6, and allowing the arm 2 to achieve a natural chest-crossing posture.
[0036] This invention, through precise mechanical design, improves the articulation of the shoulder structure, allowing it to move a wider range of motion in multiple directions. This enables the humanoid model to more naturally perform actions requiring high shoulder mobility, such as crossing its arms. At the same time, it does not compromise the overall appearance of the humanoid model, maintaining its aesthetic appeal.
[0037] In some implementations, such as Figure 4 As shown, the aforementioned trunk joint 3 may be provided with a limiting stop surface 10, which is used to limit the second joint 5 in the contracted state to prevent the second joint 5 from rotating and to lock the second joint 5.
[0038] In the example above, locking the second joint 5 helps maintain the contracted state of the shoulder structure and improves the stability of the shoulder structure in the contracted state.
[0039] To achieve the function of the aforementioned limiting stop surface 10, in some embodiments, such asFigure 4 As shown, the aforementioned limiting stop surface 10 may include a first stop surface 101 and a second stop surface 102. In the retracted state, the first stop surface 101 engages with the other end 52 of the second joint to prevent the second joint 5 from rotating in the first direction w1; and the second stop surface 102 engages with one end 51 of the second joint to prevent the second joint 5 from rotating in the second direction w2. The first direction w1 and the second direction w2 are opposite in direction.
[0040] In the above example, by designing two different stop surfaces on the torso joint 3 to cooperate with the second joint 5, the second joint 5 can be locked to prevent it from shaking.
[0041] In some implementations, such as Figure 5 As shown, when the second joint 5 is locked, the first joint 4 can drive the second joint 5 to rotate relative to the torso joint 3, causing the torso joint 3 and the second joint 5 to be misaligned, thereby causing the first stop surface 101 and the second stop surface 102 to be misaligned and separated from the second joint 5, ending the stopping state of the two stop surfaces on the second joint 5, and thus unlocking the second joint 5.
[0042] In the example above, once the second joint 5 is unlocked, the shoulder structure can be switched to an extended state for the user to play with.
[0043] To achieve the function of the aforementioned first stop surface 101, in a specific application example, such as Figure 4 As shown, the other end 52 of the aforementioned second joint may have a first arcuate surface 50a, and the aforementioned first stop surface 101 may be a second arcuate surface. The other end 52 of the second joint cooperates with the second arcuate surface through the first arcuate surface 50a to prevent the second joint 5 from rotating in the first direction w1.
[0044] To achieve the function of the aforementioned second stop surface 102, in a specific application example, such as Figure 4 As shown, one end 51 of the aforementioned second joint may have a first plane 50b, and the aforementioned second stop surface 102 may be a second plane. One end 51 of the second joint engages with the second plane through the first plane 50b to prevent the second joint 5 from rotating in the second direction w2.
[0045] In some implementations, such as Figure 3 As shown, the other end 32 of the aforementioned torso joint has a first mounting groove 301, and one end 41 of the first joint is installed in the first mounting groove 301 and is hinged to the opposite side walls of the first mounting groove 301 through the first hinge shaft 1a.
[0046] In the above example, by installing one end 41 of the first joint in the first mounting slot 301 of the torso joint 3, installation space can be saved, and the assembly structure of both the torso joint 3 and the first joint 4 is more compact.
[0047] In some embodiments, as shown in Figure 3 one end 51 of the aforementioned second joint has a second mounting slot 501, the other end 42 of the aforementioned first joint is installed in the second mounting slot 501, and is hinged to the opposite two side walls of the second mounting slot 501 by a second hinge shaft 2a.
[0048] In the above example, by installing the other end 42 of the first joint in the second mounting slot 501 of the second joint 5, installation space can be saved, and the assembly structure of both the first joint 4 and the second joint 5 is more compact.
[0049] In some embodiments, as shown in Figure 2 one end of the aforementioned arm joint 6 has a third mounting slot 601, the other end 52 of the second joint is installed in the third mounting slot 601, and is hinged to the opposite two side walls of the third mounting slot 601 by a third hinge shaft 3a.
[0050] In the above example, by installing the other end 52 of the second joint in the third mounting slot 601 of the arm joint 6, installation space can be saved, and the assembly structure of both the second joint 5 and the arm joint 6 is more compact.
[0051] In some embodiments, the utility model also provides a humanoid model toy, which comprises the shoulder structure of any one of the above-mentioned humanoid model toys. Since the humanoid model toy adopts the shoulder structure, compared with the prior art in which the torso joint 3 is directly hinged to the arm joint 6, the shoulder structure of the utility model increases the first joint 4 and the second joint 5, so that when the shoulder structure is in an unfolded state, the arm joint 6 is away from the torso 1, the interference of the torso 1 on the rotation of the arm joint 6 is reduced, the movable range of the arm joint 6 is increased, and the arm 2 can realize a natural hugging posture.
[0052] The above only describes the preferred embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by using the utility model specification and the drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
