[0039] Example 1

[0040] Existing methods for simulating the opening and closing of petals and leaves typically involve multiple actors forming a circle, each wearing petals and leaves on their arms. The actors then simulate the opening and closing of the petals and leaves by stretching and retracting their arms. This method requires the actors to work together tacitly, which wastes manpower. Furthermore, the frequent arm movements increase the actors' workload and can easily cause fatigue.

[0041] In view of this, an embodiment of the present invention provides a simulated branch and leaf opening and closing device, including: a drive component, a lifting steel frame 400, a transmission component and a bracket component. The drive component is connected to the lifting steel frame 400 and is used to drive the lifting steel frame 400 to rise or fall. The transmission component is installed on the lifting steel frame 400, and the transmission component is connected to the bracket component. The transmission component can drive the bracket component to swing while the lifting steel frame 400 rises or falls.

[0042] The drive assembly drives the lifting steel frame 400 up and down. Simultaneously, the transmission assembly drives the support assembly to swing. The petals and branches are mounted on the support assembly to simulate the opening and closing of the petals and branches. The simulated branch and leaf opening and closing device has a simple structure and mechanically simulates the opening and closing of the petals and branches without the need for actors, saving manpower and reducing the actors' workload.

[0043] In an optional manner of this embodiment, the driving assembly includes a motor 100 and a hydraulic cylinder 200 , the output shaft of the motor 100 is connected to the hydraulic cylinder 200 , and the telescopic end of the hydraulic cylinder 200 is connected to the lifting steel frame 400 .

[0044] See Figure 1 The motor 100 drives the hydraulic cylinder 200 to perform telescopic movement, and the telescopic movement of the hydraulic cylinder 200 drives the lifting steel frame 400 to rise or fall. The motor 100 can be controlled at a fixed speed by the PLC program, thereby realizing the control of the rising or falling speed of the lifting steel frame 400.

[0045] Furthermore, the motor 100 is installed on the main steel frame 300, the lifting steel frame 400 is arranged inside the main steel frame 300, and the hydraulic cylinder 200 is arranged in the vertical direction.

[0046] Please continue to see Figure 1 The motor 100 is installed near the top of the main steel frame 300, the lifting steel frame 400 is set at the middle and lower position inside the main steel frame 300, the hydraulic cylinder 200 is arranged vertically, and the telescopic end of the hydraulic cylinder 200 is in the vertical direction, thereby driving the lifting steel frame 400 to rise and fall in the vertical direction.

[0047] In an optional manner of this embodiment, the lifting steel frame 400 includes an upper steel frame 410, lifting pillars 420 and a lower steel frame 430. The upper steel frame 410 and the lower steel frame 430 are arranged at intervals in the vertical direction. The upper steel frame 410 and the lower steel frame 430 are connected by the lifting pillars 420, and the transmission assembly is installed on the upper steel frame 410 and the lower steel frame 430.

[0048] See Figure 1 and Figure 2The upper steel frame 410 and the lower steel frame 430 are connected and fixed by multiple lifting struts 420. The upper steel frame 410 and the lower steel frame 430 are both regular octagonal frame structures. The transmission assembly is installed on the upper steel frame 410 and the lower steel frame 430. As the upper steel frame 410 and the lower steel frame 430 rise or fall synchronously, the transmission assembly also rises and falls, driving the bracket assembly to swing.

[0049] In an optional manner of this embodiment, the transmission assembly includes multiple upper transmission rod groups and multiple lower transmission rod groups. The multiple upper transmission rod groups are circumferentially installed on the upper steel frame 410, and the multiple lower transmission rod groups are circumferentially installed on the lower steel frame 430.

[0050] Since both the upper steel frame 410 and the lower steel frame 430 in this embodiment are regular octagonal frame structures, the corresponding number of upper transmission rod groups and lower transmission rod groups is also eight. The eight upper transmission rod groups are evenly installed along the circumference of the upper steel frame 410, and the eight lower transmission rod groups are evenly installed along the circumference of the lower steel frame 430. The upper transmission rod groups rise and fall synchronously with the rise and fall of the upper steel frame 410 and drive the bracket assembly to swing. The lower transmission rod groups rise and fall synchronously with the rise and fall of the lower steel frame 430 and drive the bracket assembly to swing.

[0051] Furthermore, the upper transmission rod group includes a first upper linkage rod 510 and a second upper linkage rod 520. One end of the first upper linkage rod 510 is fixedly connected to the upper steel frame 410, and the other end is rotatably connected to the second upper linkage rod 520. The end of the second upper linkage rod 520 away from the first upper linkage rod 510 is connected to the bracket assembly.

[0052] See Figure 1 The first upper linkage rod 510 is rotatably connected to the second upper linkage rod 520. One end of the first upper linkage rod 510 is fixed to the upper steel frame 410, while the second upper linkage rod 520 passes through the first limiting structure 600 on the main steel frame 300 and is connected to the bracket assembly. The rise or fall of the upper steel frame 410 causes the first upper linkage rod 510 to rise and fall synchronously, while the second upper linkage rod 520 rotates simultaneously. Due to the limiting effect of the first limiting structure 600, the second upper linkage rod 520 can only swing, thus achieving the swing of the bracket assembly.

[0053] Similarly, the lower transmission rod group includes a first lower linkage rod 710 and a second lower linkage rod 720. One end of the first lower linkage rod 710 is fixedly connected to the lower steel frame 430, and the other end is rotatably connected to the second lower linkage rod 720. The end of the second lower linkage rod 720 away from the first lower linkage rod 710 is connected to the bracket assembly.

[0054] Please continue to see Figure 1The first lower linkage rod 710 is rotatably connected to the second lower linkage rod 720. One end of the first lower linkage rod 710 is fixed to the lower steel frame 430, while the second lower linkage rod 720 passes through the second limiting structure 800 on the main steel frame 300 and is connected to the bracket assembly. The rise or fall of the lower steel frame 430 causes the first lower linkage rod 710 to rise and fall synchronously, while the second lower linkage rod 720 rotates simultaneously. Due to the limiting effect of the second limiting structure 800, the second lower linkage rod 720 can only swing, thus achieving the swing of the bracket assembly.

[0055] In an optional manner of this embodiment, the bracket assembly includes an upper bracket 910 and a lower bracket 920 , the upper bracket 910 is connected to the second upper linkage rod 520 , and the lower bracket 920 is connected to the second lower linkage rod 720 .

[0056] See Figure 2 The upper bracket 910 is connected to the end of the second upper linkage rod 520, and the lower bracket 920 is connected to the end of the second lower linkage rod 720. The petals and branches are mounted on each of the upper bracket 910 and the lower bracket 920. When the upper bracket 910 and the lower bracket 920 swing, the opening and closing of the petals and branches can be simulated.

[0057] When the simulated branch and leaf opening and closing device is in use, the petals and branches are first installed on the upper bracket 910 and the lower bracket 920, and then the motor 100 is controlled to work at a fixed time and speed through the PLC program. The extension and retraction of the hydraulic cylinder 200 drives the lifting steel frame 400 to move up and down, and then drives the upper bracket 910 and the lower bracket 920 to swing at a certain angle, thereby simulating the opening and closing shape of the petals and branches.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
