Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, and in particular to a stage lighting effect switching mechanism. Background Technology

[0002] In stage lighting applications, the conventional method for achieving diverse pattern effect switching relies on a turntable structure with multiple effect sheets stacked on top of each other. This design inevitably causes at least one turntable to deviate from the optimal focal plane of the optical path, resulting in blurred projected images, edge distortion, or reduced sharpness, thus weakening the visual expressiveness of the stage lighting. Furthermore, due to the focal length characteristics of the non-optimal plane, designers must repeatedly adjust and compensate for the pattern shapes of the effect sheets to accommodate the optical path deviation. This process not only significantly increases the complexity and workload of pattern design but also prolongs the product development cycle and increases production costs and the risk of errors.

[0036] See Figures 1 to 5 This utility model embodiment proposes a stage lighting effect switching mechanism, including a main board 1, a mounting plate 2, two symmetrically arranged effect units 3, and a driving component 4; the main board 1 is provided with a light projection hole 10, the mounting plate 2 is located above the main board 1 and slides with the main board 1, the mounting plate 2 is provided with a light projection waist hole 20, the effect units 3 are located at both ends of the light projection waist hole 20, and the effect unit 3 includes a rotating shaft 30, a turntable 31, a first gear plate 32, a bushing 33, a second gear plate 34, a first transmission component 35, and a second transmission component 36;

[0037] The rotating shaft 30 passes through the turntable 31, the first gear disk 32 and the bushing 33 in sequence and is coaxially connected to the second gear disk 34. The rotating shaft 30 is connected to the turntable 31. The first gear disk 32 is sleeved on the bushing 33. The second gear disk 34 is rotatably embedded in the bushing 33. The bushing 33 is connected to the mounting plate 2.

[0038] The turntable 31 is provided with light-transmitting holes 37 and a plurality of pattern modules 38. The light-transmitting holes 37 and each of the pattern modules 38 are evenly distributed around the center of the turntable 31. The pattern modules 38 mesh with the first toothed disk 32. The first transmission member 35 is connected to the first toothed disk 32 in a transmission manner. The second transmission member 36 is connected to the second toothed disk 34 in a transmission manner.

[0039] The driving component 4 drives the mounting plate 2 to move radially along the projection hole 10 so that the two ends of the projection hole 20 can be aligned with the projection hole 10 and form a projection channel.

[0040] Specifically, the mounting plate 2 and the main board 1 can slide together via a linear guide or a ball bearing slider. The projection hole 20 is an elongated opening structure with semi-circular ends. The length of the projection hole 20 can be adjusted according to the diameter of the projection hole 10 and the layout of the two effect units 3, for example, set to more than twice the diameter of the projection hole 10 to ensure alignment accuracy during light path switching. The rotating shaft 30 passes through the turntable 31, the first gear plate 32, and the bushing 33. The two ends of the rotating shaft 30 are rigidly connected to the turntable 31 and the second gear plate 34 respectively via bolts. Figure 5As shown, the upper part of the bushing 33 is a sleeve, and the lower part is a disc. The diameter of the sleeve is smaller than that of the disc. The sleeve and the disc are coaxially and integrally formed. The disc has a cylindrical cavity for accommodating the second gear disc 34. An opening is also provided on one side of the cylindrical cavity for the transmission connection between the second gear disc 34 and the second transmission member 36. In some embodiments, the second gear disc 34 and the turntable 31 can also be provided with keyways to improve the robustness of the three. The first gear disc 32 is fitted with a rotating shaft 30 and rotates on the drive member 4 of the first transmission member 35. The meshing relationship between the first gear disc 32 and the pattern module 38 can be achieved by a gear pair. For example, a gear ring is provided on the outer edge of the pattern module 38 and directly meshes with the tooth surface of the first gear disc 32 to achieve the angle adjustment function. The transmission connection between the first transmission member 35 and the first gear disc 32 can be achieved by chain drive or gear drive. The driving component 4 can be implemented using a cylinder, chain drive, ball screw, or hydraulic cylinder. For example, the extension and retraction of the cylinder piston rod can drive the mounting plate 2 to move radially along the projection hole 10, thereby achieving dynamic alignment between the projection waist hole 20 and the projection hole 10. The turntable 31 is provided with a light-transmitting hole 37 and several pattern modules 38, which are evenly distributed around the center of the turntable 31. The light-transmitting hole 37 provides a direct light path without any effect, while the pattern modules 38 are used to achieve diverse visual effects. The pattern modules 38 mesh with the first gear plate 32, and the rotation of the first gear plate 32 directly drives the pattern modules 38 to rotate, thereby switching the light output effect. The second transmission component 36 is connected to the second gear plate 34 to drive the turntable 31 to rotate, thereby enabling different pattern modules 38 to rotate on the projection channel.

[0041] In this embodiment, the mechanism drives the mounting plate 2 to move via the drive component 4, aligning one end of the projection hole 20 with the projection hole 10, thereby activating the corresponding effect unit 3; then the second transmission component 36 drives the turntable 31 to rotate, selecting the light-transmitting hole 37 or the target pattern module 38; the first transmission component 35 drives the individual pattern module 38 to fine-tune the angle and calibrate the projection orientation.

[0042] Furthermore, the driving component 4 is a through-type lead screw stepper motor 40, and the two ends of the lead screw of the through-type lead screw stepper motor 40 are threadedly connected to the transmission blocks 41. The transmission blocks 41 are fixed on the main board 1, and the through-type lead screw stepper motor 40 is fixed on the mounting plate 2.

[0043] Specifically, the through-type lead screw stepper motor 40 converts rotational motion into linear displacement through the threaded engagement of the lead screw and the transmission block 41. Since transmission blocks 41 are provided at both ends of the lead screw, driving force can be applied simultaneously from both symmetrical ends during rotation, effectively preventing the mounting plate 2 from tilting or jamming due to unilateral force. Furthermore, the through-type lead screw stepper motor 40 is directly fixed to the mounting plate 2; this integrated design simplifies the transmission path, eliminates potential backlash errors in intermediate links, and improves the system's response speed and overall rigidity. In practical implementation, the lead of the through-type lead screw stepper motor can be set according to actual needs, for example, in the range of 2mm to 10mm.

[0044] Furthermore, both the first transmission component 35 and the second transmission component 36 include a transmission motor, a pulley, and a synchronous belt; the output shaft of the transmission motor is connected to the pulley, and the first gear disc 32 and the second gear disc 34 are respectively connected to the corresponding pulleys via synchronous belts.

[0045] Furthermore, the first gear disk 32 includes a first annular gear disk 320 and a second annular gear disk 321 arranged coaxially; the first annular gear disk 320 is meshed with the timing belt, and the second annular gear disk 321 is meshed with each of the pattern modules 38.

[0046] Furthermore, the pattern module 38 is either a color filter toothed disk or a perforated toothed disk. The color filter toothed disk controls the color of light through filtering principles and can use filters of different colors. The perforated toothed disk forms specific light effect patterns through physical perforation, by processing the desired perforation pattern onto a metal or plastic toothed disk. The color filter toothed disk directly affects the color of light, utilizing its inherent filtering properties to achieve color transformation. The perforated toothed disk forms specific patterns through physical obstruction, and its meshing connection with the first transmission component 35 ensures precise alignment during rotation.

[0047] Furthermore, the hollowed-out toothed disc includes a fixing ring and a patterned toothed disc; the turntable 31 is provided with several through holes, the patterned toothed disc is rotatably mounted on the fixing ring, the fixing ring is fixed in the through holes, and the patterned toothed disc is engaged with the second annular toothed disc 321.

[0048] Furthermore, the turntable 31 has a first magnetic post (not shown) on the side facing the mounting plate 2, and the mounting plate 2 has a first magnetic sensor (not shown) adapted to the first magnetic post at the corresponding position; the pattern module 38 has a second magnetic post, and the mounting plate 2 has a second magnetic sensor adapted to the second magnetic post at the corresponding position.

[0049] Specifically, as the turntable 31 rotates, the first magnetic post on the turntable 31 generates a periodic magnetic field change signal at the first magnetic sensor. This signal is collected in real time and converted into angular information of the turntable 31, thus ensuring the long-term stability of the turntable 31's positioning. The second magnetic post on the pattern module 38 provides a unique position identifier for each module. When the pattern module 38 switches, the second magnetic sensor determines whether the module has accurately reached the target position by sensing changes in magnetic field strength. This dual detection mechanism not only avoids minor offsets caused by gear meshing clearance or vibration, but also significantly improves the position correction capability during complex light effect switching processes. In addition, since both the magnetic post and the magnetic sensor adopt a non-contact design, the cumulative error caused by mechanical friction is effectively eliminated, while avoiding interference from external additional structures on the light path, thus ensuring the accurate presentation of the projected light effect.

[0050] Furthermore, such as Figure 6 As shown, the stage lighting effect switching mechanism also includes two mirror-symmetrical flame disc assemblies 5, which are located between the turntable 31 and the mounting plate 2 and are used to output flame light effects.

[0051] Furthermore, the flame disk assembly 5 includes a base plate 50, a swing arm 51, a flame toothed disk 52, a third transmission component 53, and a fourth transmission component 54;

[0052] The third transmission component 53 and the fourth transmission component 54 are fixed on the base plate 50, and the base plate 50 is connected to the mounting plate 2.

[0053] One end of the swing arm 51 is provided with a transmission tooth 55, which is sleeved on the rotating shaft of the third transmission component 53. The fourth transmission component 54 is connected to the transmission tooth 55 via a synchronous belt.

[0054] The flame toothed disc 52 is fixedly mounted on the other end of the swing arm 51 by a bearing. The rotating shaft of the third transmission component 53 is provided with a drive tooth 56. The swing arm 51 is provided with a plurality of sequentially meshing driven teeth 57. The drive tooth 56 is connected to the flame toothed disc 52 through the driven teeth 57.

[0055] Specifically, the flame gear disk 52 is used to output flame light effects. The flame gear disk 52 is made of high-temperature resistant PEEK material with a thickness of up to 3mm. Flame textures are laser-engraved on its surface, and it is connected to the swing arm 51 via bearings. A toothed ring is machined on the outer edge of the flame gear disk 52, meshing with the driven tooth 57 on the swing arm 51. A transmission tooth 55 at one end of the swing arm 51 is fitted onto the rotating shaft of the third transmission component 53, allowing it to rotate synchronously with the shaft. A fourth transmission component 54 is connected to the transmission tooth 55 via a synchronous belt, thereby driving the swing arm 51 to revolve around the rotating shaft, enabling the flame gear disk 52 to quickly switch between entering and leaving the projection channel. The third transmission component 53 drives the drive tooth 56 on the output shaft, which in turn drives the driven tooth 57 on the swing arm 51 to rotate, causing the driven tooth 57 to drive the flame gear disk 52 to rotate. Combined with the flame textures, this outputs a dynamic flashing effect simulating flames.
