Description

Technical Field

[0001] The utility model relates to the technical field of deformable toys, in particular to a deformable mecha model toy. Background Art

[0002] Mecha model toys generally involve transformation between two forms: humanoid and vehicle. During the play process of children, the deformation of the toy can develop children's thinking and cultivate their hands-on ability at the same time. However, in existing deformable toys, the form changes are mostly from humanoid robots to vehicle carriers. The structural design and play design are similar, and the homogeneous competition is relatively serious. There is a lack of design for changing from humanoid to abstract geometric bodies. Secondly, existing toys mainly change between two forms, with relatively single gameplay, low freedom, limited fun in playing experience, and lack of imagination space. In addition, mecha model toys with form changes often have difficulty in realizing the mutual use of molds for humanoid limbs, and the development cost is relatively high. Therefore, the utility model proposes a deformable mecha model toy. Summary of the Utility Model

[0016] Working principle: This utility model includes three forms: mecha model form, solid disc form and dragon-shaped mechanical arm form;

[0017] 1. Taking the first ring as an example, the steps for transforming the mecha model into a solid disc are as follows:

[0018] Step S1, separate the second arc-shaped member from the central circular member; separate the third fastener from the third groove, separate the second fastener from the second groove, and screw the second fastener into the second arc-shaped member.

[0019] Step S2: Deform the first annular component, which serves as the hand of the mecha model. The finger assembly rotates clockwise into the interior of the palm assembly, the palm assembly rotates counterclockwise 90° until its upper edge aligns with the lower edge of the forearm assembly, the thumb assembly rotates into the recess between the palm assembly and the forearm assembly, the elbow joint assembly and the axis of the component below it rotate 180°, then the upper arm assembly and the axis of the component below it rotate 180°, and the shoulder armor assembly rotates counterclockwise until its outer contour and the forearm assembly close together to form a portion of the annulus. After the first arcuate component closes and becomes part of the annulus, the entire first arcuate component rotates around the shoulder ball joint and the rotating shaft, joining the second arcuate component to form a portion of the annulus. At this point, the first annular component is completely deformed.

[0020] Step S3, deforming the third arc-shaped part serving as the leg of the mecha model; separating the interconnected first annular part and the second annular part, then rotating the forefoot component clockwise to the inside of the calf component, and also rotating the rear foot component clockwise to form an arc with the calf component, the second thigh component and the component axis below it rotate 180°, the first thigh component rotates 90° clockwise around the third hip joint, and then rotates the second hip joint 90° upward, and then rotates the entire third arc-shaped part 90° counterclockwise around the first hip joint, and finally rotates the first thigh component inward so that the third groove of the first thigh component engages with the first snap fastener.

[0021] In step S4, the rear sole assembly is embedded in the depression on the outer edge of the palm assembly, so that the third arc-shaped member is connected and fixed to the first arc-shaped member. At this point, the first arc-shaped member, the second arc-shaped member and the third arc-shaped member are connected end to end in sequence to form a closed loop.

[0022] Step S5, deforming the central circular component serving as the torso of the mecha model toy; rotating the head component to be in the same straight line with the neck component, rotating the ear component backward to be parallel to the neck component, squeezing the head component and the tail component inward, and shrinking them into the interior of the central component.

[0023] Step S6: Nest the first annular member and the second annular member on the central circular member; rotate the third buckle member by 90 degrees, wrap the first annular member and the second annular member around the outer peripheral surfaces of the first circular member and the second circular member respectively, align the third groove with the rotated third fastener and insert it for fixation, so that the first annular member and the second annular member are nested with the first circular member and the second circular member respectively to form a solid disk. Finally, slide the first circular member and the second circular member towards the central member until they come into contact to complete the deformation.

[0024] Second, the deformation steps of the dragon-shaped robotic arm form are as follows: Separate the first annular member and the first circular member, and the second annular member and the second circular member. Embed the rear foot assembly of the first annular member into the gap of the palm assembly of the second annular member and form a fixation, thereby deforming into the dragon-shaped robotic arm form.

[0025] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0026] In the present utility model, by providing the first annular member and the second annular member serving as the limbs of the mecha model toy, and the central circular member serving as the torso of the mecha model toy, the first annular member and the second annular member are composed of the first arc member, the second arc member and the third arc member.

4. A deformable mecha model toy according to claim 1, wherein, The first arc member serves as the hand of the mecha model shape, and it includes a shoulder armor assembly, a shoulder joint assembly, a large arm assembly, an elbow joint assembly, a small arm assembly, and a palm assembly.

5. A deformable mecha model toy according to claim 4, wherein The shoulder joint assembly is provided with a shoulder ball socket joint member, and the shoulder ball socket joint member is connected to the shoulder spherical joint member of the second arc member, so that the first arc member can move around the shoulder ball socket joint of the second arc member. The large arm assembly is connected to the small arm assembly through the elbow joint assembly. The other end of the small arm assembly is movably connected with a palm assembly. The palm assembly includes a finger assembly and a thumb assembly that are movably arranged.

6. A deformable mecha model toy according to claim 4, characterized in that, The third arc member serves as the leg of the mecha model shape, and it includes a multi-axis hip joint assembly, a first thigh assembly, a second thigh assembly, a calf assembly, and a foot sole assembly.

7. A deformable mecha model toy according to claim 6, characterized in that, The multi-axis hip joint assembly is composed of a first hip joint, a second hip joint, and a third hip joint, which are sequentially axially connected. The first hip joint is axially movably connected to the U-shaped hip connector of the second arc-shaped member. The third hip joint is connected to the first thigh assembly. One end of the first thigh assembly connected to the multi-axis hip joint assembly is provided with a third groove, which is adapted to the first buckle member of the U-shaped hip connector. The other end of the first thigh assembly is connected to the second thigh assembly, and the second thigh assembly is connected to the calf assembly. The middle part of the calf assembly is hollow, and the foot sole assembly is rotatably connected to the middle part of the calf assembly. The foot sole assembly includes a front foot sole assembly and a rear foot sole assembly.

8. A deformable mecha model toy according to claim 6, characterized in that, The first annular member and the second annular member can form the shape of a dragon-shaped robotic arm. By inserting the foot sole assembly of the first annular member into the gap of the palm assembly of the second annular member and forming a fixation, it is deformed into the shape of a dragon-shaped robotic arm.
