Description

Technical Field

[0001] This utility model relates to the technical field of cross-disciplinary fields of handicrafts and mechanical transmission, specifically to an acrylic dynamic ornament. Background Technology

[0002] Acrylic dynamic ornaments are made primarily of acrylic. Acrylic has excellent light transmission, is lightweight, comes in a variety of colors, and is easy to process and shape, giving the ornaments a more transparent and modern aesthetic. They can be made into various shapes (such as animals, people, and abstract figures) according to design requirements. Common types include human figures, animal figures, geometric shapes, and scene subjects. Human figures are themed around various human figures, such as anime characters, celebrities, athletes, and cartoon characters. By moving their heads or arms, the ornaments become more interesting and interactive. Common examples include the Luo Shengdeng creative head-shaking ornament and the Sun Yingsha-themed acrylic spring rocking ornament.

[0003] Existing dynamic acrylic ornaments mostly achieve dynamic effects through simple single-axis rotation or single-part swinging, such as only the head or a single limb making reciprocating movements. The parts lack coordinated linkage, the overall movement is mechanical and the aesthetics are limited, making it difficult to meet users' needs for rich dynamic scenes. Some ornaments that achieve multi-part movement often use multiple drive sources (such as multiple motors) to control different parts separately, resulting in a bulky overall structure, complicated assembly, and high energy consumption. Utility Model Content

[0004] To address the issues of limited dynamic forms and multiple driving sources, the purpose of this invention is to provide an acrylic dynamic ornament.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an acrylic dynamic ornament, comprising a support plate, wherein a rear swing arm, a first head, a second head, a front swing arm, a torso, a hind leg, a first front leg, and a second front leg are movably disposed on one side of the support plate; a first head support shaft, a drive shaft, a first leg pivot shaft, a second leg pivot shaft, and a third leg pivot shaft are rotatably connected to the outer surface of the support plate; one end of each of the first, second, and third leg pivot shafts passes through the support plate and is fixedly connected to a second eccentric connecting plate; one end of each of the three second eccentric connecting plates is respectively connected to the hind leg, the second front leg, and the third front leg. One side of the leg and the first front leg are fixedly connected. One end of the first head support shaft is fixedly connected to the middle of the first head. Two second head support shafts are rotatably provided on the outer surface of the support plate. One end of the two second head support shafts is sleeved on the second head. One side of the outer surface of one of the second head support shafts is fixedly sleeved with the rear swing arm. One end of the other second head support shaft passes through the second head and is fixedly connected to the front swing arm. A frame is fixedly connected to one side of the support plate. A micro motor is fixedly installed on one side of the frame. The output end of the micro motor is fixedly connected to one end of the drive shaft.

[0006] Preferably, a drive gear is fixedly sleeved on the outer surface of the drive shaft near the micro motor, a driven shaft is rotatably provided on one side of the support plate, two irregular plates are fixedly sleeved on the outer surface of the driven shaft, a first driven gear is fixedly connected to one end of the driven shaft, the outer surface of the first driven gear meshes with the outer surface of the drive gear, a swing rod is fixedly connected to one end of each of the two second head support shafts, a pulley is rotatably connected to one end of each of the two swing rods, the outer surfaces of the two pulleys slide against the outer surfaces of the two irregular plates respectively, a second driven gear is fixedly connected to the other end of the second leg shaft, and a third driven gear is fixedly connected to the other end of the third leg shaft.

[0007] Preferably, the irregular plate is configured as a cam structure with a non-circular curve outer contour. When the driven shaft drives it to rotate, the non-circular curve contour change can stably drive the pulley to make periodic lifting and lowering motion. This allows the swing rod to drive the second head support shaft to achieve uniform and regular reciprocating swing, ensuring smooth and uninterrupted movement of the rear swing arm, front swing arm, and second head. At the same time, the cam structure has high transmission efficiency and stable operation, and can accurately control the swing amplitude and frequency, improving the coordination and aesthetics of the dynamic movement of the ornament.

[0008] Preferably, a battery electrically connected to the micro motor is fixedly installed on the lower part of one side of the support plate, which can provide a stable and independent DC power supply to the micro motor. The ornament can operate autonomously without the need for an external power cord, so that the placement of the ornament is not limited by the power interface, making the usage scenarios more flexible. At the same time, the battery installed on the lower part of the support plate can optimize the overall center of gravity distribution, prevent the ornament from tipping over due to the movement of the upper parts, and improve the stability and ease of use of the ornament.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model uses a single micro motor as a power source, combined with various mechanical structures such as gear meshing, eccentric connecting plates, linkage transmission, and cam drive, to transform rotational motion into coordinated swinging of multiple parts of the head, swing arm, torso, and legs, achieving rich and continuous dynamic effects. The overall structure is compact and has high space utilization. Power is transmitted through gear meshing, synchronous pulleys and synchronous belts to ensure consistent movement rhythm of each component and avoid misalignment. At the same time, the linkage design of the transmission rod and transmission plate enables the first head to move in conjunction with the movements of other components, improving the overall dynamic coordination and aesthetics.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-5 As shown, this utility model provides an acrylic dynamic ornament, including a support plate 11. The support plate 11 serves as a support base, and a first head support shaft 19, a drive shaft 21, a first leg shaft 22, a second leg shaft 23, and a third leg shaft 24 are mounted on one side of the support plate 11 by a rotatable connection. The connection between each shaft and the support plate 11 is clearance-fitted to ensure smooth rotation.

[0020] The rear swing arm 10 and the front swing arm 14 are respectively fixedly sleeved with two second head support shafts 20. The second head 13 is sleeved on the ends of the two second head support shafts 20. The first head 12 is fixed to one end of the first head support shaft 19. The body 15 is fixedly connected to the upper end of the reciprocating swing plate 28. The hind leg 16, the second front leg 18, and the first front leg 17 are respectively connected to the first leg pivot 22, the second leg pivot 23, and the third leg pivot 24 through the second eccentric connecting plate 25, so as to realize the swing driven by the rotation of the shaft.

[0021] The micro motor 32 is fixed to the frame 31, and its output end is connected to the drive shaft 21. The drive gear 33 is sleeved on the side of the drive shaft 21 near the motor. The driven shaft 34 is fixed with the special plate 35 and the first driven gear 36, and the first driven gear 36 meshes with the drive gear 33. One end of the two second head support shafts 20 is connected to the swing rod 37. The pulley 38 at the end of the swing rod 37 is in contact with the outer surface of the special plate 35. The second driven gear 39 and the third driven gear 40 are fixed to the ends of the second leg shaft 23 and the third leg shaft 24, respectively, and mesh with the drive gear 33 and the second driven gear 39 in sequence.

[0022] The first leg shaft 22 is connected to the third driven gear 40 via a synchronous pulley 41 and a synchronous belt 42. The transmission rod 29 is sleeved on one of the second head support shafts 20, and its end pin is embedded in the groove of the transmission plate 30. The transmission plate 30 is fixed to the first head support shaft 19. The battery is installed at the lower part of the support plate 11 and is connected to the micro motor 32 via a wire to supply power. The driving gear 33 meshes with the first driven gear 36 to drive the driven shaft 34 and the special plate 35 to rotate. The outer contour of the cam of the special plate 35 pushes the pulley 38, causing the swing rod 37 to drive the second head support shaft 20 to rotate reciprocally, thereby realizing the periodic swing of the rear swing arm 10, the front swing arm 14, and the second head 13. Simultaneously, the second head support shaft 20, through the cooperation of the transmission rod 29 and the transmission plate 30, drives the first head support shaft 19 to rotate, causing the first head 12 to swing synchronously. The drive shaft 21 drives the first eccentric connecting plate 26 to rotate, and through the connecting rod 27, pushes the reciprocating swing plate 28 to swing back and forth, realizing the swing of the body 15. The drive gear 33 sequentially drives the second driven gear 39 and the third driven gear 40 to rotate, causing the second leg shaft 23 and the third leg shaft 24 to rotate. The third driven gear 40 drives the first leg shaft 22 to rotate through the synchronous belt 42. Each leg shaft is converted into the swing of the hind leg 16, the first front leg 17, and the second front leg 18 through the second eccentric connecting plate 25.

[0023] Working principle: The swinging parts of the first head 12, front swing arm 14, rear swing arm 10, and body 15 are started by the micro motor 32, and the output end drives the drive shaft 21 to rotate. The drive gear 33 on the drive shaft 21 rotates synchronously and, through meshing with the first driven gear 36, transmits power to the driven shaft 34, causing the driven shaft 34, the coaxial profiled plate 35, and the first driven gear 36 to start rotating. When the drive shaft 21 rotates, the first eccentric connecting plate 26 rotates with it, driving the reciprocating swing plate 28 to reciprocate through the connecting rod 27, thereby driving the body 15 to reciprocate. At the same time, the first head support shaft 19 is directly connected to the first head 12. When the profiled plate 35 on the driven shaft 34 rotates, its cam-shaped outer contour pushes the pulley 38, causing the swing rod 37 to drive the two second head support shafts 20 to rotate periodically. The two second head support shafts 20 are fixedly connected to the rear swing arm 10 and the front swing arm 14, respectively, thereby realizing the swing cycle of the front swing arm 14 and the rear swing arm 10. When one of the second head support shafts 20 rotates under the drive of the profiled plate 35, the swing rod 37, and other components, the transmission rod 29 fixedly connected to it swings synchronously. Since one end of the transmission rod 29 is slidably connected to the slide groove of the transmission plate 30 through a pin, during the swinging process, it will push the transmission plate 30 to reciprocate around the axis of the first head support shaft 19, thereby driving the first head 12 to rotate cyclically.

[0024] In the swinging parts of the hind leg 16, the first front leg 17, and the second front leg 18, during the rotation of the drive shaft 21, the driving gear 33 drives the first driven gear 36 to rotate, and simultaneously drives the second driven gear 39 to rotate. The second driven gear 39 then drives the third driven gear 40 to rotate. Through the meshing of the driving gear 33, the second driven gear 39, and the third driven gear 40, the first leg shaft 22, the second leg shaft 23, and the third leg shaft 24 are rotated. The second eccentric connecting plate 25 at the end of the shaft rotates with the shaft, and through the eccentric structure, the rotational motion is converted into the swinging motion of the hind leg 16, the first front leg 17, and the second front leg 18, simulating leg dynamics and realizing the swinging motion.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
