[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0028] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Furthermore, when an element is considered to be "transmission-connected" to another element, the two can achieve power transmission, and its specific implementation method can be implemented using the existing technology, which will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation method.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0031] Please refer to the attached Figure 1 -Attached Figure 7 , the utility model embodiment proposes a LED dynamic mechanical wing, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the LED dynamic mechanical wings include a shell 1 and a driving component and two groups of transmission components installed in the shell 1. Luminous swinging parts 2 are rotatably installed on both sides of the shell 1 to form the shape of wings. The driving component includes a driving motor 3, a reducer 4, a driving gear 5 and two driven gears 6 meshing with each other. The output shaft of the driving motor 3 is connected to the input shaft of the reducer 4, and the output shaft of the reducer 4 is fixedly connected to the driving gear 5. The driving gear 5 is meshed with one of the driven gears 6, and one of the driven gears 6 is connected to one of the swinging parts 2 through a group of transmission components to drive one of the swinging parts 2 to swing back and forth up and down, and the other driven gear 6 is connected to the other swinging part 2 through another group of transmission components to drive the other swinging part 2 to swing back and forth synchronously up and down.

[0032] It is understandable that after the driving motor 3 is started as a power source, its output shaft rotates and the speed is adjusted through the reducer 4, and the output shaft of the reducer 4 drives the driving gear 5 to rotate. The function of the reducer 4 is to reduce the speed of the driving motor 3 and increase the torque to adapt to the torque and speed required for the mechanical wing to swing. The driving gear 5 is meshed with the two driven gears 6. Through the gear meshing transmission principle, when the driving gear 5 rotates, it will drive the two driven gears 6 to rotate synchronously in the opposite direction.

[0033] The working principle of the utility model is as follows: the output power of the driving motor 3 is amplified by the torque of the reducer 4 and then transmitted to the driving gear 5, and the driving gear 5 drives the driven gear 6 connected thereto to rotate. Since the two driven gears 6 are meshed with each other, when one driven gear 6 rotates, it will drive the other driven gear 6 to rotate in the opposite direction. Each driven gear 6 is connected to the swinging member 2 on one side through a set of transmission components, and the transmission components convert the rotational motion of the driven gear 6 into the up and down reciprocating swinging motion of the swinging member 2. Due to the synchronous action of the two sets of transmission components, the swinging members 2 on both sides (i.e., the LED luminous wing structure) will be driven by the driving motor 3. According to a predetermined rule, the swinging members 2 will swing synchronously up and down according to a predetermined rule, simulating the flight posture of real wings. During the swinging process of the swinging member 2, its built-in LED light will light up or flash with the swinging of the wings, thereby forming a dynamic and dazzling visual effect. The utility model has a compact structure. Through the ingenious cooperation of the gear transmission mechanism composed of the driving motor 3, the reducer 4, the driving gear 5 and the driven gear 6 and the transmission components, it is realized that one driving motor 3 drives two swinging members 2 to swing synchronously.

[0034] In a preferred scheme of the present embodiment, the transmission assembly includes a first connecting rod 7, a second connecting rod 29, a first positioning shaft 8, and a second positioning shaft 9. The first positioning shaft 8 is fixedly mounted on the side surface of the corresponding driven gear 6. One end of the first connecting rod 7 is rotatably connected to the first positioning shaft 8. The other end of the first connecting rod 7 is rotatably connected to one end of the second connecting rod 29. The other end of the second connecting rod 29 is fixedly connected to one end of the corresponding swinging member 2. One end of the second positioning shaft 9 is fixed on the housing 1. The other end of the second positioning shaft 9 passes through the second connecting rod 29 and the second connecting rod 29 can rotate around the second positioning shaft 9.

[0035] Specifically, a first ring 10 is provided at one end of the first connecting rod 7 , a first bearing is installed in the first ring 10 , and the first connecting rod 7 is connected to the first positioning shaft 8 through the first bearing.

[0036] Specifically, the transmission assembly also includes a third positioning shaft 11, a second ring 12 is provided at the other end of the first connecting rod 7, a second bearing is installed in the second ring 12, the third positioning shaft 11 is connected to the second bearing, and one end of the second connecting rod 29 is movably sleeved in the third positioning shaft 11.

[0037] Specifically, the second connecting rod 29 and the second positioning shaft 9 are connected via a third bearing.

[0038] It can be understood that, the first positioning shaft 8 is fixedly installed on the side of the driven gear 6, and one end of the first connecting rod 7 is rotatably connected to the first positioning shaft 8. The first positioning shaft 8 serves as a pivot point, so that the rotation of the driven gear 6 can drive the first connecting rod 7 connected thereto to move together. Since the other end of the first connecting rod 7 is rotatably connected to one end of the second connecting rod 29, and the other end of the second connecting rod 29 is fixedly connected to one end of the corresponding swing member 2, the movement of the first connecting rod 7 will drive the movement of the second connecting rod 29, and the other end of the second connecting rod 29 is fixedly connected to one end of the swing member 2, so the rotation of the second connecting rod 29 will directly drive the swing member 2 to move, and one end of the second positioning shaft 9 is fixed on the housing 1, and its role is to serve as a fulcrum for the rotation of the second connecting rod 29, and the other end of the second positioning shaft 9 passes through the second connecting rod 29, so that the second connecting rod 29 can rotate around the second positioning shaft 9.

[0039] When the driving motor 3 is started, the driving system composed of the reducer 4, the driving gear 5 and the driven gear 6 finally converts the rotational motion of the gear into the swinging motion of the second connecting rod 29, thereby driving the swinging member 2 to swing back and forth up and down, simulating the dynamic effect of the wings.

[0040] In a preferred solution of this embodiment, a partition plate 13 is provided inside the housing 1 to separate the interior of the housing 1 into a front space and a rear space, the drive motor 3 and the reducer 4 are fixedly mounted on one side of the partition plate 13, the driving gear 5, two driven gears 6 and two sets of transmission components are located on the other side of the partition plate 13, and the output shaft of the reducer 4 is fixedly connected to the driving gear 5 after passing through the partition plate 13. This has the advantages of convenient installation and convenient maintenance and repair of the equipment in the later stage, and the drive motor 3 and the reducer 4 are centrally arranged at the rear, which is convenient for early installation and later maintenance and repair.

[0041] In this embodiment, two fourth bearings are respectively installed on one side of the partition plate 13 and on the rear shell plate of the shell 1, and a rotating shaft 14 is installed between the fourth bearing on one side of the partition plate 13 and the fourth bearing on the rear shell plate of the shell 1. One end of the two rotating shafts 14 passes through the partition plate 13 respectively and is fixedly connected to the two driven gears 6 one by one.

[0042] Two rotating shafts 14 are respectively inserted between the fourth bearing on one side of the partition plate 13 and the fourth bearing on the rear shell plate of the housing 1. One end of each of the two rotating shafts 14 is fixedly connected to a driven gear 6, ensuring that the driven gear 6 can rotate smoothly and without deviation. Such a design not only enhances the stability of the driven gear 6 during rotation, but also reduces the energy loss caused by friction, and improves the working efficiency and service life of the overall mechanical structure. At the same time, this dual-bearing support structure can better disperse the load, ensuring the stability and accuracy of the rotation of the driven gear 6 under the drive motor 3.

[0043] It can be understood that the cooperation of the rotating shaft 14, the first positioning shaft 8, the third positioning shaft 11, and the second positioning shaft 9 forms the classic four-point lever arm principle, and the four points are used as force support and angle rotation to form a lever support, and the rotating shaft 14 and the second positioning shaft 9 are used as positioning, and the output rotation of the connecting force of the driving gear 5 and the two driven gears 6 drives the first connecting rod 7 and the second connecting rod 29 as an angle adjustment to drive the swing member 2 to form an up and down angular movement.

[0044] In this embodiment, the swing member 2 includes a flip seat 15 and a mounting plate 16, one end of the flip seat 15 is fixedly connected to the transmission assembly, and the other end of the flip seat 15 is fixedly connected to one end of the mounting plate 16. Figure 7 As shown, an LED light board 17 is installed on the mounting plate 16 , and swing-out grooves 18 are respectively provided on the two side plates of the housing 1 .

[0045] It is understandable that one end of the flip seat 15 is connected to the transmission assembly in a fixed manner, so that when the transmission assembly is acted upon by the driving force of the driving assembly, the flip seat 15 can perform a reciprocating up and down swinging motion. The other end of the flip seat 15 is fixed to one end of the mounting plate 16, and the main function of the mounting plate 16 is to carry and fix the LED light board 17. By setting the swinging clearance groove 18 on the two side panels of the shell 1, its purpose is to provide sufficient activity space for the up and down swinging of the swinging member 2 (i.e., the flip seat 15 and the mounting plate 16), avoid collision with the shell 1 during the swinging process, and ensure that the entire mechanical wing structure can operate smoothly and unhindered.

[0046] In a preferred solution of this embodiment, a PMMA light diffuser plate 19 is further mounted on the mounting plate 16 , and the PMMA light diffuser plate 19 covers the LED light board 17 .

[0047] It can be understood that the PMMA light diffuser plate 19 can effectively disperse the light emitted by the LED light board 17 evenly, avoiding the strong glare caused by direct illumination, making the light soft and evenly distributed, greatly improving the visual comfort and viewing effect, and at the same time improving the brightness consistency: through the refraction and diffusion effect of the PMMA light diffuser plate 19, the brightness difference between the LED lamp beads can be reduced, making the brightness of the entire wing surface more consistent, enhancing the overall effect of the wing dynamic lighting, in addition, it can also protect the LED light board 17: The PMMA light diffuser plate 19 can also play a certain protective role, reduce the erosion of dust on the LED light board 17, and extend the service life of the LED light board 17.

[0048] In a preferred solution of the present embodiment, an LED wall washer lamp 20 is installed on the inner top of the housing 1 , and a transparent window 21 is provided on the front shell plate of the housing 1 .

[0049] It can be understood that by setting up the LED wall washer light 20, the internal space of the shell 1 can be illuminated, increasing the atmosphere and mechanical style. By setting up a transparent window 21 on the front shell plate of the shell 1, the beauty of the movement of the mechanical gears inside the shell 1 can be better and more intuitively viewed, bringing a better visual experience.

[0050] In this embodiment, a motor control mainboard 24 is further provided inside the housing 1 for controlling the operation of the drive motor 3, and a display screen 25 is provided on one side of the housing 1. In addition, a reading disk 26 is also installed on one of the rotating shafts 14, and an optical coupler 27 is installed above the reading disk 26.

[0051] It is understandable that the optical coupler 27 element installed above the reading disk 26 is mainly used to detect the rotation position of the reading disk 26. The optical coupler 27 element uses the principle of photoelectric induction. When the scale or mark on the reading disk 26 passes through the gap between the optical coupler 27 transmitter and the receiver, the output state of the optical coupler 27 will be changed, thereby realizing real-time and accurate detection of the rotation angle of the rotating shaft 14. The display screen 25 can be used to display and adjust various parameters of the equipment, such as the working mode of the drive motor 3, fault alarm information, etc., to facilitate the staff to monitor and debug the equipment.

[0052] In addition, an LED light control board is also provided inside the housing 1 for controlling the light color and brightness of the LED lights on the LED light board 17, thereby forming an independently controlled LED light emitting effect.

[0053] In this embodiment, the partition plate 13 and the rear shell plate of the shell 1 are connected by

[0054] The housing 1 is supported by four positioning pillars 28; a hanging fixed branch pipe 22 is also installed on the top of the housing 1, and a buckle 23 is installed on the top of the hanging fixed branch pipe 22 for hanging the mechanical wings. The LED dynamic mechanical wings proposed by the utility model can be applied to bars, concerts, music festivals, large-scale events, commercial spaces, high-end entertainment venues, etc.

[0055] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which are all protected by the utility model.
