Description

Technical Field

[0001] This utility model relates to the field of handicraft manufacturing technology, specifically to a linkage structure for large-scale handicrafts. Background Technology

[0002] For large-scale handicrafts, achieving coordinated movements between their various parts to simulate realistic motion has become a crucial direction for innovation. Currently, some handicrafts on the market with coordinated structures suffer from unreasonable structural design. For example, some handicrafts have overly simple coordinated structures, capable only of single or limited movements, failing to vividly depict complex dynamic effects; while others, although possessing rich movements, suffer from imprecise connections and transmissions between components, resulting in stiff, unnatural movements that negatively impact the overall aesthetic appeal. Regarding mechanical transmission, some existing coordinated structures employ traditional methods, such as simple gear or linkage transmissions, which are insufficient to meet the diverse movement needs of large-scale handicrafts. Furthermore, the design of existing coordinated structures for large-scale handicrafts often fails to adequately consider the integration of artistic form and mechanical structure. In many cases, the mechanical structure is too abrupt, disrupting the overall artistic beauty of the handicraft and failing to achieve a perfect unity of art and technology. Utility Model Content

The two rear thighs are connected to the buttocks via a rear main shaft lower linkage frame, a rear main shaft upper linkage frame, and a fixed connecting rod. The rear thighs are connected to the two rear lower legs. The two rear thighs are connected to two middle locking connecting blocks, two upper locking connecting blocks, two lower locking connecting blocks, two hip and knee connecting pins, two insertion blocks, two insertion slots, two fixed movable blocks, and two rear support rods in mutual cooperation.

[0005] As a preferred embodiment of this utility model, the head-to-body connecting block is embedded in the head-to-body connecting groove, the head-to-body connecting block is rotatably connected to the head-to-body connecting groove, and the head-to-body connecting block is installed on the top of the head.

[0006] As a preferred embodiment of this utility model, both the first and second rib-moving connecting rods are hinged to the rear side of the body, and the first and second rib-moving connecting rods are rotatably connected.

[0007] As a preferred embodiment of this utility model, one end of the front connecting rod is hinged to the front thigh via a front connecting shaft, and the other end of the front connecting rod is connected to the body via a frame drive shaft and a front thigh connecting movable block. The front thigh is rotatably connected around the front connecting shaft.

[0008] As a preferred technical solution of this utility model, the lower linkage frame of the rear main shaft and the upper linkage frame of the rear main shaft are fixedly connected to the buttocks, and the two ends of the fixed connecting rod are respectively hinged to the lower linkage frame of the rear main shaft and the rear thigh. The two rear thighs are connected by a hip-knee connecting pin.

[0009] As a preferred technical solution of this utility model, the connecting crank is inclined and hinged to the two front thighs and the two rear thighs with one end higher than the other.

[0010] As a preferred embodiment of this utility model, anti-slip pads are provided inside both the upper and lower movable grooves.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Through the ingenious connection and coordinated operation of various components, such as the linkage design of the head and torso, and the front and hind legs, it can simulate an extremely rich variety of postures and movements, completely changing the monotonous and mechanical nature of traditional handicrafts. This large-scale handicraft can present a variety of complex and natural dynamics similar to those of real living beings, such as walking, breathing, and twisting, greatly enhancing its artistic expression and aesthetic appeal, bringing viewers a more vivid and realistic visual experience, and strengthening the artistic appeal and attractiveness of the handicraft;

[0013] 2. The unique connection between the head-to-body connecting block and the head-to-body connecting groove gives the head flexible multi-angle rotation capability. According to design requirements, the head can rotate freely within a large angle range, easily presenting different orientations and postures, vividly showcasing the dynamism of the artwork, expressing the animal's alertness and observation, and further enriching the expressive forms of the artwork.

[0014] 3. Through the hinged design of the first and second rib-moving links with the body, the body can achieve realistic swinging movements. It can simulate the rise and fall of the rib cage when a living organism breathes, or the twisting posture of the body during walking or running, making the craft seem to have life, greatly enhancing the sense of realism and dynamism, making it easier for viewers to resonate and immerse themselves in the artistic atmosphere created by the craft.

[0015] 4. Through innovative connection structures between the front and rear thighs, the movement of an animal's legs, such as stepping and flexion / extension, is accurately simulated. The front thighs achieve natural lifting and lowering movements through components such as the front connecting rod, while the rear thighs complete stable flexion / extension movements through components such as the rear main shaft and lower linkage frame. The two work in perfect harmony, as smooth and natural as the leg movements of a real animal, greatly improving the realism of the artwork and making the dynamic expression of the entire artwork more delicate and realistic.

[0016] 5. Through the ingenious application of the connecting curved rod, the coordinated and unified movements of the front and rear legs are achieved. When the front thigh moves, the connecting curved rod can transmit the motion to the rear thigh, and according to the designed motion logic, make the rear thigh make corresponding and coordinated movements. This ensures that when the craftwork simulates walking, running, and other movements, the posture conforms to the movement laws of real living organisms, avoiding disjointed or uncoordinated movements, making the overall movement more natural and smooth, and improving the quality and aesthetics of the craftwork.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] Please see Figure 1-6This utility model provides a linkage structure for a large handicraft, including a head 1, a neck 2, a torso 3, two front thighs 4, two rear thighs 5, a buttocks 6, a rib-driven connecting rod 9, an upper movable groove 10, a fixed frame rod 15, and two front lower legs 17. The head 1 is connected to the torso 3 through the cooperation of a head-to-torso connecting block 7 and a head-torso connecting groove 8. One end of the rib-driven connecting rod 9 and the second rib-driven connecting rod 33 is connected to the torso 3. The upper movable groove 10 is located in the torso 3. The two front thighs 4 are connected to the torso 3 through a front connecting rod 11, a front connecting shaft 12, a frame drive shaft 13, and a front thigh insert movable block 14. The fixed frame rod 15 is connected to the front support rod 16. The two front lower legs 17 are connected to the front thighs 4 through grafting pins 18. The two front thighs 4 are connected to a connecting crank rod. One end of the connecting rod 19 is rotatably connected, and the other end of the connecting rod 19 is rotatably connected to two lower movable slots 20. The two lower movable slots 20 are located at the bottom of the corresponding two rear thighs 5. The two rear thighs 5 are connected to the buttocks 6 through the rear main shaft lower linkage frame 21, the rear main shaft upper linkage frame 22, and the fixed connecting rod 23. The rear thighs 5 are connected to the two rear calves 24. The two rear thighs 5 are connected to the two middle locking connecting blocks 25, the two upper locking connecting blocks 26, the two lower locking connecting blocks 27, the two hip and knee connecting pins 28, the two plug-in blocks 29, the two plug-in slots 30, the two fixed movable blocks 31, and the two rear support rods 32 in mutual cooperation. The head 1 can rotate relative to the body 3 through the cooperation of the head top torso connecting block 7 and the head top torso connecting slot 8, providing the head's movement expression for the craft. Rib linkage 1 (9) and rib linkage 2 (33) are connected to the torso 3. Under power, they can drive the torso to produce swinging and other movements, simulating postures similar to breathing or twisting. The front thigh 4 is connected to the torso via the front link 11, front connecting shaft 12, frame drive shaft 13, and front thigh connecting block 14, enabling lifting and lowering movements, simulating leg movements. The fixed frame rod 15 and front support rod 16 provide support and stability to the structure. The front lower leg 17 is connected to the front thigh 4 via the grafting pin 18, moving with the movement of the front thigh. The connecting crank rod 19 connects the front thigh 4 and the rear thigh 5, transmitting the movement of the front thigh to the rear thigh and coordinating the movements of the front and rear legs. The rear thigh 5 is connected to the buttock 6 via the rear main shaft lower linkage 21, rear main shaft upper linkage 22, and fixed link 23, enabling flexion and extension movements. The rear lower leg 24 is connected to the rear thigh 5 to complete the corresponding movements. The components work together to achieve overall coordination of the artwork. Through a unique connection and combination method, complex linkages between multiple parts of a large-scale artwork are achieved. Compared to the single or simple movements of traditional handicrafts, this structure can simulate richer and more natural postures and movements, greatly enhancing the dynamic display effect of the artwork. At the same time, this structural design fully considers the mechanical transmission and motion coordination between different parts, ensuring the smoothness and stability of the overall movement.

[0026] The head-to-body connecting block 7 is embedded in the head-to-body connecting groove 8, and the head-to-body connecting block 7 and the head-to-body connecting groove 8 are rotatably connected. The head-to-body connecting block 7 is installed on the top of the head 1. When the head 1 needs to rotate, the head-to-body connecting block 7 rotates relative to the head-to-body connecting groove 8, causing the head to rotate at multiple angles, thus presenting different head postures. The embedded rotating connection method results in a compact structure and flexible rotation. Compared with the traditional simple hinge method, it can provide a more stable and multi-angle rotation effect, making the head movements more natural and diverse, and enhancing the expressiveness of the craft.

[0027] Both rib-driven connecting rod 1 (9) and rib-driven connecting rod 2 (33) are hinged to the rear side of the body part 3, and are rotatably connected. When driven by a power source such as a motor, they can rotate around the hinge point. Working together, they cause the body part 3 to swing back and forth or left and right, simulating the breathing and twisting movements of living organisms. Through the hinged design of the two rib-driven connecting rods, relatively complex swinging movements of the body part are achieved. Unlike the fixed or simple swinging methods of the body part in traditional handicrafts, this design more vividly expresses the dynamic feel of the handicraft and increases its artistic appeal.

[0028] One end of the front connecting rod 11 is hinged to the front thigh 4 via the front connecting shaft 12, and the other end of the front connecting rod 11 is connected to the body 3 via the drive shaft 13 and the front thigh connecting movable block 14. The front thigh 4 rotates around the front connecting shaft 12. When power is applied, the front connecting rod 11 rotates around the front connecting shaft 12, causing the front thigh 4 to perform reciprocating movements such as lifting and lowering around the front connecting shaft 12, achieving a walking motion similar to that of an animal's leg. This articulated connection design accurately simulates the movement of an animal's leg, making the movement of the front thigh more realistic. Compared with traditional leg connection structures, its flexibility and realism are significantly improved, making the dynamic display of the craft more vibrant.

[0029] The lower linkage frame 21 and upper linkage frame 22 of the rear main shaft are fixedly connected to the hip 6. The two ends of the fixed connecting rod 23 are hinged to the lower linkage frame 21 and the posterior thigh 5, respectively. The two posterior thighs 5 are connected by a hip-knee connecting pin 28. When power is input, the fixed connecting rod 23 drives the posterior thigh 5 to flex and extend around the hip-knee connecting pin 28 and other connection points, with the posterior lower leg 24 following suit, achieving the normal movement posture of the posterior leg. This structural design rationally distributes the force during the movement of the posterior thigh, and through the coordinated work of multiple components, ensures the stability and smoothness of the flexion and extension movements of the posterior thigh. Compared with traditional posterior leg structures, it better simulates the movement of real organisms, improving the overall quality and aesthetic value of the craftwork.

[0030] The connecting crank 19 is inclined and hinged at one end to the two front thighs 4 and the two rear thighs 5, with one end higher than the other. When the front thighs 4 move, the connecting crank 19 changes its angle with the movement of the front thighs, thereby causing the rear thighs 5 to move accordingly. This coordinates the movements of the front and rear legs, making the movement of the craft more consistent with the movement logic of actual living organisms.

[0031] Both the upper movable groove 10 and the lower movable groove 20 are equipped with anti-slip pads. The anti-slip pads inside the upper movable groove 10 and the lower movable groove 20 increase the friction between the groove and the sliding parts such as sliders or rollers. When the parts slide in the groove, the anti-slip pads can prevent the sliding parts from slipping, ensuring that the parts move accurately along the predetermined trajectory, thus guaranteeing the accuracy and stability of the linkage structure movement.

[0032] In this invention, the overall linkage structure achieves complex and coordinated linkage of multiple parts through the cooperation of the head-to-body connecting block 7 and the head-to-body connecting groove 8 between the head 1 and the torso 3, the driving of the torso by the first rib-moving connecting rod 9 and the second rib-moving connecting rod 33, the coordination of the front thigh 4 and the rear thigh 5 with various connecting components such as the front connecting rod 11 and the rear main shaft lower linkage frame 21, and the transmission of the movement of the front and rear legs by the connecting crank rod 19. Under the action of power, each component, according to the designed connection relationship and movement mode, jointly simulates rich and natural posture movements. The head rotation connection is achieved by the head-to-body connecting block 7 being embedded in the head-to-body connecting groove 8, forming a rotational connection between the two. When head movement is required, the head-to-body connecting block 7 rotates relative to the head-to-body connecting groove 8, driving the head to achieve flexible rotation at multiple angles. The body swaying drive is hinged to the rear side of the body 3 via rib-driven connecting rod 1 9 and rib-driven connecting rod 2 33. Under the drive of the power source, the two rotate around the hinge point, cooperating to drive the body to produce back-and-forth or left-and-right swaying movements, simulating the breathing, twisting and other postures of an organism. The front thigh movement simulation is achieved by connecting one end of the front connecting rod 11 to the front thigh 4 via the front connecting shaft 12, and the other end connecting to the body 3 via the frame drive shaft 13 and the front thigh insertion movable block 14. When the power is applied, the front connecting rod 11 rotates around the front connecting shaft 12, driving the front thigh to perform reciprocating movements such as lifting and lowering around the front connecting shaft, accurately simulating the walking movements of an animal's legs. The hind thigh movement is coordinated by being fixedly connected to the buttocks 6 via the rear main shaft lower linkage frame 21 and the rear main shaft upper linkage frame 22. The two ends of the fixed connecting rod 23 are respectively hinged to the rear main shaft lower linkage frame 21 and the hind thigh 5. When power is input, the fixed connecting rod 23 drives the posterior thigh to flex and extend around the hip-knee connecting pin 28 and other connection points, with the posterior lower leg 24 following suit. Simultaneously, it coordinates with the posterior thigh via the connecting crank 19. The coordination between the posterior and posterior legs is achieved by the connecting crank 19, one end of which is inclinedly hinged to the posterior thigh 4, and the other end to the posterior thigh 5. When the posterior thigh moves, the connecting crank changes its angle accordingly, thereby driving the posterior thigh to move accordingly, achieving coordinated and unified movements of the posterior and posterior legs, making the movement of the craftwork more consistent with biological movement logic. Precise movement of the movable grooves is achieved through anti-slip pads inside the upper movable groove 10 and lower movable groove 20, increasing friction with sliding components such as sliders or rollers, preventing slippage, ensuring precise sliding of components within the grooves along a predetermined trajectory, and guaranteeing the accuracy and stability of the linkage structure's movement.
