Description

Technical Field

[0001] This utility model relates to the field of exhibition products technology, and in particular to a transmission structure for a lifelike doll. Background Technology

[0002] In the fields of commercial display, folk culture dissemination, and exhibition, lifelike mascots, with their realistic appearance and ability to simulate specific actions, have become important carriers for attracting crowds and conveying scene information. Currently, various functional lifelike mascot exhibits exist on the market. For example, the automatic noodle-slicing mascot commonly seen at the entrance of noodle shops typically uses a motor-driven linkage mechanism to move the mascot's arms in reciprocating noodle-slicing motions, visually demonstrating the noodle-making process. Similarly, the automatic millstone mascots placed at the entrance of pharmacies or grain stores use transmission components to rotate the millstone, and the mascot's hand movements simulate the traditional grinding scene. These lifelike mascots play a role in enhancing shop visibility and increasing the visual appeal of the scene.

[0003] However, existing humanoid dolls still have significant shortcomings in terms of motion complexity, structural adaptability, and display effect. Current humanoid doll technology has technological gaps in simulating lower limb circulatory movements, adapting to bicycle suspended display scenarios, and realizing the linkage between actions and carriers. There is an urgent need for a simulation device that can stably realize the doll's automatic cycling action, adapt to the bicycle suspended support, and has a simple and reliable structure, so as to make up for the shortcomings of existing technologies and meet the display needs in diverse scenarios. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a transmission structure for a simulated doll riding a unicycle.

[0005] To solve the above-mentioned technical problems, this utility model discloses a transmission structure for a simulation doll, including a base frame and a C-shaped arm. The bottom end of the C-shaped arm is fixedly connected to the rear end of the base frame, and the top end of the C-shaped arm is fixedly connected to a wheel bracket facing the base frame. A wheel body is provided inside the wheel bracket, and a first rotating shaft for simulating leg movement is fixedly passed through the middle of the wheel body and arranged along the axial direction of the wheel body. The first rotating shaft is rotatably connected to the wheel bracket through a bearing. Foot pedals are fixedly installed at both ends of the first rotating shaft. The wheel bracket is also fixedly installed with a rotating component for driving the first rotating shaft to rotate. An upwardly extending support rod is fixedly connected to the top of the C-shaped arm or the wheel bracket. A second rotating shaft for simulating shoulder movement is provided on the side of the support rod and can rotate relative to the support rod. The second rotating shaft is arranged in a vertical direction. A rotating linkage mechanism is provided between the foot pedal and the second rotating shaft so that the second rotating shaft reciprocates when the foot pedal rotates.

[0006] The wheel bracket is an inverted U-shaped structure, so that the wheel bracket extends downwards with a pair of hinge ears. Each hinge ear has a mounting hole at its end for mounting a bearing, and the first shaft passes through the two mounting holes.

[0007] The rotating linkage mechanism includes a linkage assembly and a third rotating shaft. The third rotating shaft is arranged laterally and rotatably mounted on the bottom of the support rod. The linkage assembly includes an L-shaped linkage for simulating the lower leg and foot and a straight linkage for simulating the thigh. The lateral section of the L-shaped linkage is fixed to the foot pedal, and the longitudinal section of the L-shaped linkage is hinged to one end of the straight linkage through a hinge. The other end of the straight linkage is fixed to the second rotating shaft so that the second rotating shaft reciprocates when the straight linkage moves.

[0008] The bottom end of the second rotating shaft is located above the middle of the third rotating shaft. A toggle bar extending radially outward is fixed to the bottom end of the second rotating shaft. An upwardly inclined toggle piece is fixed to the middle of the third rotating shaft. A through hole is opened on the end of the toggle piece facing the toggle bar, and the end of the toggle bar is inserted into the through hole.

[0009] The support rod has a first horizontal beam fixed to its bottom, a first sleeve fixed to the side of the first horizontal beam, and a third rotating shaft passing through the first sleeve so that the third rotating shaft can rotate relative to the support rod.

[0010] The top surface of the first crossbeam is fixedly equipped with a first support frame for mounting the lifelike doll.

[0011] The support rod is fixed to the side with a second sleeve, and the second rotating shaft passes through the second sleeve so that the second rotating shaft can rotate relative to the support rod.

[0012] The top of the support rod is fixedly connected to a second horizontal beam, and the top surface of the second horizontal beam is fixedly installed with a second support frame for mounting the simulated human figure.

[0013] The top of the third rotating shaft is fixed to a rotating disk, and the outer periphery of the rotating disk has multiple support holes arranged circumferentially for installing cross braces.

[0014] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0015] (1) By rotating the linkage mechanism, the first rotating shaft (and foot pedal) used to simulate leg movement is mechanically connected to the second rotating shaft used to simulate shoulder movement, so that the leg stepping action and the shoulder swinging action are driven by the same power source (rotating component) to achieve linkage. This solves the problem of isolated and uncoordinated leg and shoulder movements of existing simulation dolls, conforms to the natural laws of human movement, greatly improves the simulation degree of movement, and realizes multi-action coordinated linkage.

[0016] (2) A C-arm is used to connect the base frame and the wheel bracket to form a stable support frame. The wheel bracket supports the bearing of the first shaft, ensuring that the first shaft has a small radial offset and runs smoothly during rotation. This avoids the action jam caused by structural shaking, extends the service life of the device, and has strong structural stability.

[0017] (3) The first rotating shaft is driven by a single rotating component, and the second rotating shaft is driven synchronously by the rotating linkage mechanism. This eliminates the need for a separate drive component for the shoulder in traditional multi-action simulation dolls, reduces the number of parts, lowers the manufacturing cost, simplifies the transmission path, improves the power transmission efficiency, and has high transmission efficiency and low cost.

[0018] (4) The fixed connection structure between the C-arm and the base frame, the arrangement of the wheel brackets and the setting of the support rods can be flexibly adapted to simulation dolls of different sizes and shapes. Only the installation position of the relevant parts needs to be adjusted to meet the assembly requirements of diverse dolls, thus expanding the applicability of the structure.

[0019] (5) The second rotating shaft is arranged in the vertical direction, which is closer to the actual movement axis of the human shoulder. Combined with the transmission characteristics of the rotating linkage mechanism, the reciprocating swing trajectory of the shoulder is closer to the real human movement, which solves the problem of stiff shoulder movement caused by the traditional horizontal rotating shaft and enhances the realism of the display.

[0028] Example 1

[0029] This utility model discloses one specific embodiment of a transmission structure for a simulation doll. Please see [link / reference]. Figure 1 As shown, the transmission structure for the simulation doll includes a base frame 1, a C-shaped arm 2, a wheel bracket 3, a wheel body 32, a first rotating shaft 41, and a foot pedal.

[0030] In this embodiment, the base frame 1 is rectangular in shape and serves as the load-bearing foundation for the entire transmission structure. The bottom end of the C-arm 2 is firmly connected to the rear end of the base frame 1, providing stable support for the subsequent structure. A wheel bracket 3 is fixedly attached to the top of the C-arm 2, facing the base frame 1. The wheel bracket 3 adopts an inverted U-shaped structure, allowing it to extend downwards with a pair of hinge ears 31. Each hinge ear 31 has a mounting hole at its end for installing a bearing. The first rotating shaft 41 passes through both mounting holes, enabling it to rotate rotatably with the wheel bracket 3 via the bearing. This double-hinged-ear 31 support method effectively enhances the radial stability of the first rotating shaft 41, preventing shaft misalignment during long-term operation and improving the overall reliability of the structure. A first rotating shaft 41 is fixedly inserted through the middle of the wheel body 32 and arranged along its axial direction. The first rotating shaft 41 is used to simulate leg movement. Pedals are fixedly installed at both ends of the shaft. A rotating component (not shown) for driving the first rotating shaft 41 to rotate is also fixedly installed on the wheel bracket 3. The rotating component can be understood as a drive source composed of a motor, a power supply module and a gearbox. It is mainly used to drive the first rotating shaft 41 to rotate, thereby simulating the activity of a puppet pedaling a bicycle. The first rotating shaft 41 can be driven to rotate by a single rotating component, which reduces the number of parts, reduces manufacturing costs, and also improves the efficiency of power transmission.

[0031] In this embodiment, an upwardly extending support rod is fixed to the top of the C-shaped arm 2. The support rod integrates a transmission structure for simulating the movement of the doll's shoulders. This transmission structure is linked with the foot pedal. When the foot pedal rotates, the transmission structure can simulate the swaying of the doll's shoulders.

[0032] It should be noted that, please see Figure 1 The pedals are mainly connected to the foot structure of the dummy and are used to simulate the dummy's pedaling motion. The transmission structure includes an L-shaped link 51 for simulating the lower leg and foot and a straight link 52 for simulating the thigh. The transverse section of the L-shaped link 51 is fixed to the pedal, and the longitudinal section of the L-shaped link 51 is hinged to one end of the straight link 52 via a hinge.

[0033] Example 2

[0034] This utility model discloses a second specific embodiment of a transmission structure for a simulation doll. Please see [link / reference]. Figure 2 The main technical solution of this embodiment is the same as that of Embodiment 1. Features not explained in this embodiment are explained in Embodiment 1 and will not be repeated here. The difference between this embodiment and Embodiment 1 is that in this embodiment, the support rod is fixed to the top of the wheel bracket 3.

[0035] Combination Figures 2 to 4A second rotating shaft 42, rotatable relative to the support rod and used to simulate shoulder movement, is provided on the side of the support rod. The second rotating shaft 42 is arranged vertically, and a second sleeve 63 is fixedly connected to the side of the support rod. The second rotating shaft 42 passes through the second sleeve 63, allowing it to rotate stably relative to the support rod. This vertically arranged second rotating shaft 42 more closely matches the actual movement axis of the human shoulder, providing a structural basis for the natural simulation of shoulder movements. A rotating linkage mechanism is provided between the foot pedal and the second rotating shaft 42. This mechanism can drive the second rotating shaft 42 to swing back and forth when the foot pedal rotates, realizing the coordinated linkage of leg and shoulder movements.

[0036] Combination Figure 2 and Figure 3 The rotating linkage mechanism includes a linkage assembly and a third rotating shaft 43. The third rotating shaft 43 is arranged laterally. A first crossbeam 61, also arranged laterally, is fixedly connected to the bottom of the support rod. A first sleeve 62 is fixedly connected to the side of the first crossbeam 61. The third rotating shaft 43 passes through the first sleeve 62, thereby allowing the third rotating shaft 43 to rotate relative to the support rod. The linkage assembly includes an L-shaped linkage 51 for simulating the lower leg and foot, and a straight linkage 52 for simulating the thigh (attached). Figure 1 (Illustrated in the diagram) The transverse section of the L-shaped link 51 is fixed to the foot pedal, and the longitudinal section of the L-shaped link 51 is hinged to one end of the straight link 52 through a hinge. The other end of the straight link 52 is fixed to the second rotating shaft 42. When the foot pedal rotates with the first rotating shaft 41, the L-shaped link 51 drives the straight link 52 to move (swing back and forth within a fan-shaped range), which in turn drives the second rotating shaft 42 to swing back and forth.

[0037] Further, please see Figure 3 The bottom end of the second rotating shaft 42 is located above the middle of the third rotating shaft 43. A radially outward extending actuating bar 44 is fixedly connected to the bottom end of the second rotating shaft 42. An upwardly inclined actuating plate 45 is fixedly connected to the middle of the third rotating shaft 43. A through hole is opened at the end of the actuating plate 45 facing the actuating bar 44, and the end of the actuating bar 44 is inserted into the through hole. When the third rotating shaft 43 rotates, the actuating plate 45 pushes the actuating bar 44 through the through hole, thereby causing the second rotating shaft 42 to swing back and forth around its own axis. This transmission method, through the cooperation of the actuating plate 45 and the actuating bar 44, transmits the pedaling action of the leg to the shoulder through such mechanical linkage, making the leg and shoulder movements coordinated and unified, conforming to the natural laws of human movement, greatly improving the simulation of the movement, further optimizing the linkage effect of the leg and shoulder movements, and making the movement transmission smoother and more stable.

[0038] In addition, please see Figure 4A first support frame 71 for mounting a simulated doll is fixedly installed on the top surface of the first crossbeam 61. A second crossbeam 64 arranged laterally is fixedly connected to the top of the support rod. A second support frame 72 for mounting a simulated doll is fixedly installed on the top surface of the second crossbeam 64. Through the first support frame 71 and the second support frame 72, simulated dolls of different sizes and shapes can be flexibly adapted. Diverse assembly needs can be met simply by adjusting the installation position, greatly expanding the applicability of this transmission structure. At the same time, a rotating disk 46 is fixedly connected to the top of the third rotating shaft 43. Multiple support holes 47 arranged circumferentially for mounting cross braces are opened on the outer periphery of the rotating disk 46. These support holes 47 can be used to selectively install cross braces and other components. The cross braces mainly serve to support the shoulders of the simulated doll, and facilitate the expansion of decorative parts or interactive sensors, further enhancing the functional expandability of the structure.

[0039] The working process of the transmission structure in this embodiment is as follows: After the drive motor is powered on (the rotating component is started), the first rotating shaft 41 is driven to rotate through gear transmission, which synchronously drives the wheel body 32 and the foot pedal to make circular motion (simulating wheel rolling and leg pedaling); the foot pedal drives the L-shaped connecting rod 51 to move, which pulls the third rotating shaft 43 to swing around the first sleeve 62 through the straight connecting rod 52 (swinging back and forth within a fan-shaped range); the actuating plate 45 on the third rotating shaft 43 swings with it, and pushes the actuating bar 44 to swing back and forth through the through hole, thereby driving the second rotating shaft 42 to rotate back and forth around the second sleeve 63 by ±30° (simulating shoulder swinging). After the crossbar is installed by the rotating disk 46 on the third rotating shaft 43, combined with the simulated doll installed on the transmission structure, the coordinated linkage of the doll's whole body movements can be realized.

[0040] In summary, the transmission structure of this simulation doll forms a stable support frame through C-shaped arms 2 and wheel brackets 3, ensuring the smooth operation of the first rotating shaft 41. The use of a rotating linkage mechanism enables coordinated movement of the legs and shoulders, making the movements more in line with the laws of human movement and improving the simulation level. By using a single rotating component to drive multiple movements, the number of parts is reduced, transmission efficiency is improved, and costs are lowered. The design of the support holes 47 in the first and second support frames 72 and the rotating disk 46 further enhances the adaptability and expandability of the structure. The overall structure is stable and reliable, has rich functions, and provides excellent simulation effects.

[0041] Finally, it should be noted that the transmission structure for a simulated doll disclosed in this utility model embodiment is only a preferred embodiment of this utility model and is only used to illustrate the technical solution of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
