Description

Technical Field

[0001] This utility model relates to the technical field of trendy toy standees, and more particularly to an electric standee. Background Technology

[0002] Among trendy toy (trendy toy) derivatives, toy standees are a very popular form. They are usually presented as stand-up display boards, and their main function is to statically display printed images of specific characters (e.g., images derived from anime, games, or original intellectual property (IP)).

[0003] However, traditional standees are typically static, displaying figures and other images without moving. These static standees are often poorly constructed, and their static display format fails to effectively attract and maintain consumer attention, resulting in insufficient appeal. Furthermore, static displays lack dynamism and vitality, failing to create a lively and interesting atmosphere, leading to a monotonous and dull display effect and a limited consumer experience. Moreover, static displays that remain in the same position and posture for extended periods can easily cause visual fatigue for consumers. Traditional standees have severely impacted the consumer viewing experience and fail to meet consumer needs.

[0004] Therefore, there is an urgent need for an electric signboard to overcome the aforementioned problems. Utility Model Content

[0026] The power module is fixed on the mounting base plate, and the rotary driver and the light strip are both electrically connected to the power module.

[0027] Because the rotary driver of the electric standee of this utility model is fixed to the rear side of the mounting base, and the drive gear is fixedly connected to the output shaft of the rotary driver; the reciprocating swing conversion component and the swing gear set are both located on the rear side of the mounting base, and the first linkage and the second linkage are both pivotally connected to the rear side of the mounting base, and the rotation axis of the first linkage and the rotation axis of the second linkage are both perpendicular to the mounting base; the reciprocating swing conversion component is driven between the drive gear and the first linkage, and the second linkage is driven between the first linkage and the swing gear set; the head model component is oscillating on the front side of the mounting base, and the upper torso...

The upper torso model is fixedly connected to the second linkage, and its rotation axis coincides with that of the second linkage. The head model assembly is driven by a swaying gear set. A rotary driver drives the drive gear to rotate, which in turn drives the reciprocating sway conversion assembly to rotate the first linkage in both forward and reverse directions. The first linkage drives the second linkage to rotate in both forward and reverse directions, which in turn drives the swaying gear set to rotate in both forward and reverse directions. This design achieves multi-level coordinated oscillation, where the lower torso model swings left and right via the first linkage, the upper torso model swings left and right via the second linkage, and the head model assembly swings via the oscillating gear set. This allows the lower torso, upper torso, and head model assemblies to swing in unison, creating a dynamic display that replaces the static display structure of traditional standees. Using a rotary actuator as a single drive source to propel the complex, coordinated oscillation of multiple parts of the lower torso, upper torso, and head model assemblies results in a more sophisticated structure. This dynamic oscillation display effectively attracts and maintains consumer attention, significantly enhancing visual appeal. Furthermore, the display effect is more dynamic and vibrant, creating a lively and engaging atmosphere, preventing visual fatigue, and thus improving the consumer's viewing experience and better meeting their usage needs.

[0037] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments, but the implementation of the present invention is not limited thereto.

[0038] Please see Figures 1 to 9The electric standee 100 of this utility model includes: a mounting base plate 10, a rotary driver 20a, a drive gear 20b, a reciprocating swing conversion assembly 30, a first linkage 40, a second linkage 50, a swing gear set 60, a head model assembly 70, an upper torso model 80a, and a lower torso model 80b. The rotary driver 20a is fixed to the rear side of the mounting base plate 10, and the drive gear 20b is fixedly connected to the output shaft of the rotary driver 20a, that is, the rotation axis of the drive gear 20b coincides with the rotation axis of the output shaft of the rotary driver 20a, so that the rotary driver 20a can drive the drive gear 20b to rotate. The rotary driver 20a can specifically be a motor, but is not limited thereto. The reciprocating oscillation conversion assembly 30 and the oscillating gear set 60 are both located on the rear side of the mounting base plate 10. The first linkage 40 and the second linkage 50 are both pivotally connected to the rear side of the mounting base plate 10, and the rotation axis of the first linkage 40 and the rotation axis of the second linkage 50 are both perpendicular to the mounting base plate 10. The reciprocating oscillation conversion assembly 30 is driven between the drive gear 20b and the first linkage 40, and the second linkage 50 is driven between the first linkage 40 and the oscillating gear set 60, forming a multi-stage linkage structure. The head model assembly 70 is pivotally mounted on the front side of the mounting base plate 10. The upper torso model 80a and the lower torso model 80b are both pivotally connected to the front side of the mounting base plate 10, and the rotation axes of both the upper and lower torso models 80a are perpendicular to the mounting base plate 10. The upper torso model 80a is located below the head model assembly 70, and the lower torso model 80b is located below the upper torso model 80a. The lower torso model 80b is fixedly connected to the first linkage 40, and the rotation axis of the lower torso model 80b coincides with the rotation axis of the first linkage 40, allowing the lower torso model 80b to pivot via the first linkage 40. The upper torso model 80a is fixedly connected to the second linkage 50, and the rotation axis of the upper torso model 80a coincides with the rotation axis of the second linkage 50, so the upper torso model 80a can be driven to swing through the second linkage 50. The head model assembly 70 is driven to swing through the swing gear set 60, so the head model assembly 70 can be driven to swing through the swing gear set 60. Then, the rotary driver 20a drives the drive gear 20b to rotate, and the drive gear 20b drives the reciprocating swing conversion assembly 30 to drive the first linkage 40 to reciprocate forward and reverse rotation. The first linkage 40 drives the second linkage 50 to reciprocate forward and reverse rotation, and the second linkage 50 drives the swing gear set 60 to reciprocate forward and reverse rotation. It achieves multi-level linkage swing by having the lower torso model 80b swing back and forth from left to right by the first linkage 40, the upper torso model 80a swing back and forth from left to right by the second linkage 50, and the head model assembly 70 swing back and forth by the swing gear set 60.This allows the lower torso model 80b, upper torso model 80a, and head model component 70 to reciprocate in unison, achieving a dynamic reciprocating display. This replaces the static display structure of traditional standees. A rotary actuator 20a serves as the single driving source, driving the complex, interconnected reciprocating movements of multiple parts of the lower torso model 80b, upper torso model 80a, and head model component 70, resulting in a more sophisticated structure. This dynamic reciprocating display effectively attracts and maintains consumer attention, significantly enhancing visual appeal. Furthermore, the display effect is more dynamic and vibrant, creating a lively and engaging atmosphere, preventing visual fatigue, and thus improving the consumer's viewing experience and better meeting their usage needs. Specifically, as follows:

[0039] Please see Figures 3 to 9In this embodiment, the reciprocating oscillating conversion assembly 30 includes: a fixed plate 31, a translation plate 32, a first eccentric gear 33, a second eccentric gear 34, a third eccentric gear 35, and a transmission gear 36. The fixed plate 31 is fixed to the rear side of the mounting base plate 10, and the translation plate 32 moves on the fixed plate 31 in the left-right direction. A first eccentric shaft 331 is formed on the first eccentric gear 33, a second eccentric shaft 341 is formed on the second eccentric gear 34, and a third eccentric shaft 351 is formed on the third eccentric gear 35. That is, the rotation axis of the first eccentric shaft 331 is offset from the geometric center of the first eccentric gear 33, the rotation axis of the second eccentric shaft 341 is offset from the geometric center of the second eccentric gear 34, and the rotation axis of the third eccentric shaft 351 is offset from the geometric center of the third eccentric gear 35. The first eccentric shaft 331 and the second eccentric shaft 341 are both pivotally connected to the translation plate 32, and the third eccentric shaft 351 is pivotally connected to the fixed plate 31. The first eccentric shaft 331, the second eccentric shaft 341 and the third eccentric shaft 351 are all perpendicular to the mounting base plate 10. The first eccentric gear 33, the third eccentric gear 35 and the second eccentric gear 34 have the same eccentricity, number of teeth, module, pressure angle and tooth profile. The third eccentric gear 35 meshes with the first eccentric gear 33 and the second eccentric gear 34. The first eccentric gear 33, the third eccentric gear 35 and the second eccentric gear 34 are arranged side by side in the left and right direction. When the third eccentric shaft 351 is furthest from the first eccentric shaft 331, it is closest to the second eccentric shaft 341; conversely, when the third eccentric shaft 351 is closest to the first eccentric shaft 331, it is furthest from the second eccentric shaft 341. This ensures that the third eccentric gear 35 can smoothly and stably drive the first eccentric gear 33 and the second eccentric gear 34 to rotate synchronously, in the same direction, and at the same speed. Furthermore, the transmission gear 36 is fixedly connected to the third eccentric shaft 351, and the rotation axis of the transmission gear 36 coincides with the rotation axis of the third eccentric shaft 351. The rotation axis of the drive gear 20b is perpendicular to the mounting base plate 10, and the transmission gear 36 meshes with the drive gear 20b. Then, the driving gear 20b drives the transmission gear 36 to rotate, and the transmission gear 36 drives the third eccentric shaft 351 to rotate. The third eccentric gear 35 rotates synchronously with the third eccentric shaft 351. The third eccentric gear 35 drives the first eccentric gear 33 and the second eccentric gear 34 to rotate synchronously, in the same direction, and at the same speed. By utilizing the meshing and eccentric characteristics of the eccentric gears, and since the first eccentric shaft 331 and the second eccentric shaft 341 are both pivotally connected to the translation plate 32, the rotational motion of the third eccentric shaft 351 can be converted into the reciprocating linear translational motion of the translation plate 32 in the left and right directions.

[0040] Please continue reading. Figure 8 and Figure 9The translation plate 32 has a first positioning protrusion 321 and a second positioning protrusion 322, which are spaced apart in the left-right direction. The fixing plate 31 has a first guide groove 311 and a second guide groove 312 recessed in the left-right direction, which are opposite to each other in the left-right direction. The first positioning protrusion 321 is slidably engaged in the first guide groove 311, and the second positioning protrusion 322 is slidably engaged in the second guide groove 312. This allows the first positioning protrusion 321 to be limited and slidably engaged in the first guide groove 311 in the left-right direction, and the second positioning protrusion 322 to be limited and slidably engaged in the second guide groove 312 in the left-right direction, thereby realizing the installation structure in which the translation plate 32 moves on the fixing plate 31 in the left-right direction. The structure is simpler and more reasonable.

[0041] Please see Figure 9 Preferably, in this embodiment, the translation plate 32 has an elongated guide hole 323 arranged in the left-right direction, and the third eccentric rotating shaft 351 slides through the elongated guide hole 323. On the one hand, by providing the elongated guide hole 323 to avoid the third eccentric rotating shaft 351, the left-right movement of the translation plate 32 is prevented from being interfered with or hindered, resulting in a more efficient structure. On the other hand, when the elongated guide hole 323 moves left and right, it can also be guided and limited by the third eccentric rotating shaft 351, ensuring that the left-right movement of the translation plate 32 is more stable and secure.

[0042] Please see Figures 5 to 9 In this embodiment, the first linkage 40 includes a linkage gear 41 and a first sector gear 42. The first sector gear 42 is integrally formed on the rear side of the linkage gear 41, and the rotation axis of the linkage gear 41 coincides with the rotation axis of the first sector gear 42. A first swing mounting shaft 82 is formed on the lower torso model 80b, protruding rearward. The first swing mounting shaft 82 is vertically pivotally connected to the mounting base plate 10, thereby realizing the mounting structure of the lower torso model 80b pivotally connected to the front side of the mounting base plate 10. The pivot structure is simpler and more reasonable. The linkage gear 41 is fixedly connected to the first swing mounting shaft 82, and the rotation axis of the linkage gear 41 coincides with the rotation axis of the first swing mounting shaft 82. A rack 324 is also formed on the translation plate 32. The rack 324 is arranged in the left-right direction and meshes with the first sector gear 42. Since the rack 324 moves back and forth in a straight line along the left and right direction with the translation plate 32, the rack 324 can drive the first sector gear 42 to rotate back and forth in opposite directions. Then, the first sector gear 42 drives the connecting gear 41 to rotate back and forth in opposite directions in a synchronous manner. The connecting gear 41 can drive the lower torso model 80b to swing back and forth around the axis of the first swing mounting shaft 82, making the structure more compact and ingenious.

[0043] Please continue reading. Figures 5 to 9 In this embodiment, a second swing mounting shaft 81 protrudes rearward from the upper torso model 80a. The second swing mounting shaft 81 is vertically pivotally connected to the mounting base plate 10, thereby realizing the mounting structure in which the upper torso model 80a is pivotally connected to the front side of the mounting base plate 10. The pivotal structure is simpler and more reasonable. Furthermore, the second linkage 50 is a circular gear (not shown in the figure). The circular gear is fixedly connected to the second swing mounting shaft 81, and the rotation axis of the circular gear coincides with the rotation axis of the second swing mounting shaft 81. The circular gear meshes with the linkage gear 41. Thus, the linkage gear 41 drives the circular gear to synchronously reciprocate and switch between forward and reverse rotation. The circular gear can then drive the upper torso model 80a to swing left and right around the axis of the second swing mounting shaft 81, making the structure more compact and ingenious.

[0044] Please continue reading. Figures 5 to 9 In this embodiment, the head model assembly 70 includes: a head main model 71, a first additional swing model 72, and a second additional swing model 73. A third swing mounting shaft 711 protrudes rearward from the head main model 71, a fourth swing mounting shaft 721 protrudes rearward from the first additional swing model 72, and a fifth swing mounting shaft 731 protrudes rearward from the second additional swing model 73. The third, fourth, and fifth swing mounting shafts 711, 721, and 731 are all vertically pivotally connected to the mounting base plate 10. The head main model 71 is located between the first and second additional swing models 72 and 73 in the left-right direction. This achieves a mounting structure in which the head main model 71, the first additional swing model 72, and the second additional swing model 73 are swingably positioned on the front side of the mounting base plate 10, resulting in a simpler and more reasonable pivoting structure.

[0045] Furthermore, in this embodiment, the swing gear assembly 60 includes: a non-circular gear 61, a first driven gear 62, and a second driven gear 63. The non-circular gear 61 is fixedly connected to the third swing mounting shaft 711. A second sector gear 611 and a third sector gear 612 are integrally formed on the non-circular gear 61. The rotation axis of the second sector gear 611 and the rotation axis of the third sector gear 612 coincide with the rotation axis of the third swing mounting shaft 711, enabling the second sector gear 611 and the third sector gear 612 to swing synchronously left and right with the head body model 71. The first driven gear 62 is fixedly connected to the fourth swing mounting shaft 721, and the rotation axis of the first driven gear 62 coincides with the rotation axis of the fourth swing mounting shaft 721, enabling the first driven gear 62 to swing synchronously left and right with the first additional swing model 72. The second driven gear 63 is fixedly connected to the fifth swing mounting shaft 731. The rotation axis of the second driven gear 63 coincides with the rotation axis of the fifth swing mounting shaft 731, enabling the second driven gear 63 and the second additional swing model 73 to swing back and forth synchronously. The second sector gear 611 meshes with a circular gear, and the third sector gear 612 meshes with the first driven gear 62 and the second driven gear 63. The circular gear drives the second sector gear 611 to rotate back and forth synchronously, and the third sector gear 612 rotates back and forth synchronously with the second sector gear 611. Thus, the third sector gear 612 can drive the first driven gear 62 and the second driven gear 63 to rotate back and forth synchronously. In this way, through a step-by-step linkage structure, the head body model 71, the first additional swing model 72, and the second additional swing model 73 swing back and forth synchronously.

[0046] Please see Figure 1 , Figure 3 , Figure 5 and Figure 6The electric signboard 100 of this utility model further includes: a first leg-swinging model 80c and a second leg-swinging model 80d. The upper end of the first leg-swinging model 80c is pivotally connected to the lower end of the lower torso model 80b, and the upper end of the second leg-swinging model 80d is pivotally connected to the lower end of the lower torso model 80b. The first leg-swinging model 80c is located to the left of the second leg-swinging model 80d. The lower end of the first leg-swinging model 80c protrudes rearward to form a first guide post 83, and the lower end of the second leg-swinging model 80d protrudes rearward to form a second guide post 84. A first arc-shaped guide hole 11 and a second arc-shaped guide hole 12 are also formed on the mounting base plate 10. The first arc-shaped guide hole 11 is located to the left of the second arc-shaped guide hole 12. The first arc-shaped guide hole 11 and the second arc-shaped guide hole 12 are both arranged at an angle close to each other, and both the first arc-shaped guide hole 11 and the second arc-shaped guide hole 12 are located below the lower torso model 80b. The first guide post 83 slides through the first arc-shaped guide hole 11, and the second guide post 84 slides through the second arc-shaped guide hole 12. Therefore, when the lower torso model 80b swings left and right, it drives the first swing leg model 80c and the second swing leg model 80d to swing synchronously left and right. Through the guide and avoidance structure, the lower ends of the first swing leg model 80c and the second swing leg model 80d move up and down, guiding and avoiding their reciprocating movement. This makes the swinging of the first swing leg model 80c and the second swing leg model 80d smoother and more natural, and the structure more stable.

[0047] Alternatively, in this embodiment, the first additional swing model 72 and the second additional swing model 73 can be selected as the shape of a double ponytail hairstyle swinging on the left and right sides of the head main model 71, forming a dynamic effect where the double ponytail hairstyle swings naturally with the head main model 71. Then, the head main model 71, the first additional swing model 72, the second additional swing model 73, the upper torso model 80a, the lower torso model 80b, the first leg swing model 80c, and the second leg swing model 80d form a complete human body swing model, with a more complete and reasonable structure and a better display effect.

[0048] It should be noted that, in this embodiment, the specific gear size parameters of the driving gear 20b, transmission gear 36, first eccentric gear 33, second eccentric gear 34, third eccentric gear 35, rack 324, first sector gear 42, connecting gear 41, second sector gear 611, third sector gear 612, first driven gear 62, and second driven gear 63 can be flexibly selected by those skilled in the art according to actual usage requirements, and all are within the protection scope of this utility model. Therefore, they will not be described in detail here.

[0049] Please see Figures 1 to 6The electric signboard 100 of this utility model also includes: an outer frame 90a, a transparent inner frame 90b, a transparent panel 90c, a back cover 90d, a light strip 90e, and a power module 90d. The mounting base plate 10 is fixedly embedded in the outer frame 90a, and the transparent inner frame 90b is fixed to the front side of the mounting base plate 10. The four sides of the front side of the outer frame 90a all protrude towards the center to form an annular limiting wall 91. The transparent panel 90c is fixedly clamped between the front side of the transparent inner frame 90b and the rear side of the annular limiting wall 91. The head model assembly 70, the upper torso model 80a, the lower torso model 80b, the first swing leg model 80c, and the second swing leg model 80d are all located between the mounting base plate 10 and the transparent panel 90c. This design isolates the head model assembly 70, upper torso model 80a, lower torso model 80b, first leg model 80c, and second leg model 80d within the cavity formed by the mounting base 10, transparent panel 90c, and transparent inner frame 90b. This isolates the head model assembly 70, upper torso model 80a, lower torso model 80b, first leg model 80c, and second leg model 80d from the outside environment, preventing accidental contact that could affect their movement. This provides better protection for the head model assembly 70, upper torso model 80a, lower torso model 80b, first leg model 80c, and second leg model 80d, resulting in a safer and more reliable structure. Furthermore, the rear cover 90d is fixedly closed to the rear side of the outer frame 90a, and the mounting base 10 is located between the transparent inner frame 90b and the rear cover 90d. This design encapsulates all internal components, including the mounting base 10, rotary driver 20a, drive gear 20b, reciprocating swing conversion assembly 30, first linkage 40, second linkage 50, swing gear set 60, head model assembly 70, upper torso model 80a, lower torso model 80b, first swing leg model 80c, second swing leg model 80d, and transparent inner frame 90b, within a housing cavity formed by the rear cover 90d, outer frame 90a, and transparent panel 90c. This design better protects the internal components, prevents accidental external interference, and results in a more robust and reliable structure.

[0050] Furthermore, please refer to Figure 3 and Figure 4 The light strip 90e is placed around the inner side of the outer frame 90a, with the illumination direction of the light strip 90e facing the transparent inner frame 90b. This allows the light emitted by the light strip 90e to pass through the transparent inner frame 90b and illuminate the head model assembly 70, upper torso model 80a, lower torso model 80b, first leg model 80c, and second leg model 80d. This creates a visual effect of a surrounding light-emitting band around the front of the mounting base plate 10, allowing the head model assembly 70, upper torso model 80a, lower torso model 80b, first leg model 80c, and second leg model 80d to be displayed more clearly, with a brighter and better visual effect, and a more reasonable and aesthetically pleasing structure.

[0051] Furthermore, please refer to Figures 2 to 4 The power module 90d is fixed on the mounting base plate 10, and the rotary driver 20a and the light strip 90e are both electrically connected to the power module 90d. The power module 90d controls the rotation or stopping of the rotary driver 20a and the illumination or extinguishing of the light strip 90e. Specifically, in this embodiment, the power module 90d is provided with a swing control button 93, a light control button 94, and a power socket 95. Both the swing control button 93 and the light control button 94 extend through the cover in the front-to-back direction. Operating the swing control button 93 controls the rotation or stopping of the rotary driver 20a, and operating the light control button 94 controls the illumination or extinguishing of the light strip 90e. The rear cover 90d also has a insertion clearance hole 92 to avoid the power socket 95. The insertion clearance hole 92 is directly opposite the power socket 95 in the front-to-back direction, allowing the power socket 95 to be used for connecting external power cables for easy connection to an external power supply. It should be noted that the specific structure and working principle of the power module 90d and the swing control button 93, light control button 94 and power socket 95 are all conventional technical means well known to those skilled in the art, and therefore will not be described in detail here.

[0052] The working principle of the electric signboard 100 of this utility model will be described in detail with reference to the accompanying drawings:

[0053] First, plug the external power supply cable into the power socket 95.

[0054] When the head model 71, the first additional swing model 72, the second additional swing model 73, the upper torso model 80a, the lower torso model 80b, the first swing leg model 80c, and the second swing leg model 80d need to be swinged for display, press the swing control button 93 on the power module 90d to turn it on, so that the rotary driver 20a is powered on and starts to rotate. The rotary driver 20a drives the drive gear 20b to rotate, which in turn drives the transmission gear 36 to rotate. The transmission gear 36 then drives the third eccentric shaft 351 to rotate, and the third eccentric gear 35 rotates synchronously with the third eccentric shaft 351. The third eccentric gear 35 drives the first eccentric gear 33 and the second eccentric gear 34 to rotate synchronously, in the same direction, and at the same speed. Utilizing the meshing and eccentric characteristics of the eccentric gears, and since both the first eccentric shaft 331 and the second eccentric shaft 341 are pivotally connected to the translation plate 32, the rotational motion of the third eccentric shaft 351 can be converted into the reciprocating linear translational motion of the translation plate 32 in the left-right direction. The rack 324 moves reciprocally linearly with the translation plate 32 in the left-right direction, thereby driving the first sector gear 42 to rotate back and forth. The first sector gear 42 then drives the connecting gear 41 to rotate back and forth synchronously. The connecting gear 41 can then drive the lower torso model 80b to swing left and right around the axis of the first swing mounting shaft 82. Moreover, when the lower torso model 80b swings left and right, it drives the first swing leg model 80c and the second swing leg model 80d to swing left and right synchronously.

[0055] At the same time, the circular gear driven by the linkage gear 41 rotates synchronously back and forth, and the circular gear can drive the upper torso model 80a to swing left and right around the axis of the second swing mounting shaft 81.

[0056] Simultaneously, the circular gear drives the second sector gear 611 to rotate synchronously in both forward and reverse directions, while the third sector gear 612 rotates synchronously in both forward and reverse directions along with the second sector gear 611. Thus, the third sector gear 612 can drive the first driven gear 62 and the second driven gear 63 to rotate synchronously in both forward and reverse directions. In this way, through the step-by-step linkage structure, the head body model 71, the first additional swing model 72, and the second additional swing model 73 swing synchronously left and right.

[0057] When it is necessary to stop the swinging, press the swing control button 93 on the operating power module 90d to disconnect, and the rotation driver 20a will stop rotating. The head body model 71, the first additional swinging model 72, the second additional swinging model 73, the upper torso model 80a, the lower torso model 80b, the first swinging leg model 80c, and the second swinging leg model 80d will stop swinging.

[0058] When the light strip 90e needs to be lit or turned off, the light strip 90e can be controlled to be lit or turned off by pressing the light control button 94.

[0059] Since the rotary driver 20a of the electric stand 100 of this utility model is fixed to the rear side of the mounting base 10, and the drive gear 20b is fixedly connected to the output shaft of the rotary driver 20a; the reciprocating swing conversion assembly 30 and the swing gear set 60 are both located on the rear side of the mounting base 10, and the first linkage 40 and the second linkage 50 are both pivotally connected to the rear side of the mounting base 10, and the rotation axis of the first linkage 40 and the rotation axis of the second linkage 50 are both perpendicular to the mounting base 10; the reciprocating swing conversion assembly 30 is driven between the drive gear 20b and the first linkage 40, and the second linkage 50 is driven between the first linkage 40 and the swing gear set 60; the head model assembly 70 is oscillatingly located on the front side of the mounting base 10, and the upper torso model... Both model 80a and lower torso model 80b are pivotally connected to the front side of mounting base plate 10, and the rotation axis of upper torso model 80a and lower torso model 80b are perpendicular to mounting base plate 10; upper torso model 80a is located below head model assembly 70, and lower torso model 80b is located below upper torso model 80a; lower torso model 80b is fixedly connected to first linkage member 40, and the rotation axis of lower torso model 80b coincides with the rotation axis of first linkage member 40; upper torso model 80a is fixedly connected to second linkage member 50, and the rotation axis of upper torso model 80a coincides with the rotation axis of second linkage member 50; head model assembly 70 is drive-connected to oscillating gear set 60. The rotary driver 20a drives the drive gear 20b to rotate, which in turn drives the reciprocating swing conversion assembly 30 to drive the first linkage 40 to rotate back and forth. The first linkage 40 drives the second linkage 50 to rotate back and forth, which in turn drives the swing gear set 60 to rotate back and forth. This achieves multi-level linkage swing, where the first linkage 40 drives the lower torso model 80b to swing left and right, the second linkage 50 drives the upper torso model 80a to swing left and right, and the swing gear set 60 drives the head model assembly 70 to swing back and forth. This allows the lower torso model 80b, upper torso model 80a, and head model component 70 to reciprocate in unison, achieving a dynamic reciprocating display. This replaces the static display structure of traditional standees. Using a rotary actuator 20a as a single drive source, it propels the complex, interconnected reciprocating movements of multiple parts of the lower torso model 80b, upper torso model 80a, and head model component 70, resulting in a more sophisticated structure. This dynamic reciprocating display effectively attracts and maintains consumer attention, significantly enhancing visual appeal. Furthermore, the display effect is more dynamic and vibrant, creating a lively and engaging atmosphere, preventing visual fatigue, and thus improving the consumer's viewing experience and better meeting their usage needs.
