[0013] This application sets up a rotary drive component, in which a first servo motor drives a worm gear to rotate. The worm gear meshes with a worm wheel to drive the clamping and fixing components and the projection lamp to rotate. In conjunction with a second servo motor, a turntable drives the entire articulated frame to rotate, forming a two-dimensional precise drive. Compared with existing equipment that relies on manual adjustment, the servo motor drive can achieve precise angle control, ensuring that the projection lamp can stably complete multi-angle rotation projection and meet the needs of complex stage lighting changes.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please see Figures 1 to 6 This utility model provides a technical solution: a dynamic stage projection light, including a base 1, with a counterweight chassis 101 integrally connected to the bottom of the base 1. A battery 10 is installed in the center of the interior of the base 1, and a second servo motor 11 and a controller 12 are respectively installed on both sides of the interior of the base 1. A turntable 8 is rotatably connected to the center of the top of the base 1, and the output end of the second servo motor 11 is connected to the center of the turntable 8. A hinge frame 2 is fixed to the top of the turntable 8, and the hinge frame 2 has a "U" shape design. A hinge plate 205 and a rotation drive assembly 3 are respectively fixed to the top of the vertical plates on both sides of the hinge frame 2. Two clamping and fixing assemblies 4 are provided, and the two clamping and fixing assemblies 4 are symmetrically arranged on both sides of the interior of the hinge frame 2. The base 1 is rotatably connected to the hinge plate 205 and the rotary drive assembly 3 respectively. The projection lamp 5 is clamped between the two clamping and fixing assemblies 4. The counterweight base 101 at the bottom of the base 1 can improve the overall stability of the equipment and prevent it from tipping over during projection. The battery 10 in the base 1 can provide independent power supply for the equipment, freeing it from the constraints of an external power cord and making it suitable for stage scenes without a fixed power supply. The second servo motor 11 drives the turntable 8 to rotate the hinge frame 2. Combined with the rotary drive assembly 3, it drives the clamping and fixing assemblies 4 and the projection lamp 5 to rotate, which can realize the dual-dimensional angle adjustment of the projection lamp 5 and meet the needs of multi-directional light and shadow projection. The U-shaped hinge frame 2, together with the clamping and fixing assemblies 4 on both sides, can form a stable clamping support for the projection lamp 5 and ensure the stability of the position of the projection lamp 5 when it is working.

[0018] Please see Figure 1 , Figure 4 and Figure 5The hinge frame 2 includes a telescopic sleeve 201, a telescopic arm 202, a support plate 203, a connecting seat 204, a drive gear 206, and a toothed plate 207. Telescopic sleeves 201 are symmetrically arranged on both sides of the connecting seat 204, and a first chamber 2041 is provided at the bottom of the connecting seat 204. The first chamber 2041 is connected to the interior of both telescopic sleeves 201. A telescopic arm 202, matching the internal shape of each telescopic sleeve 201, is movably inserted into each of the two telescopic sleeves 201. The end of the telescopic arm 202 away from the connecting seat 204 extends out of the telescopic sleeve 201 and connects to the horizontal plate of the "L"-shaped support plate 203. Drive gears 206 are rotatably connected to both sides of the first chamber 2041. Furthermore, a toothed plate 207 is provided at one end of the telescopic arm 202 near the connecting seat 204. The width of the toothed plate 207 is half the width of the telescopic arm 202. The toothed surfaces of the two toothed plates 207 mesh with the two drive gears 206 respectively, and the smooth surfaces of the toothed plates 207 are in close contact with each other. The telescopic sleeves 201 on both sides of the connecting seat 204 cooperate with the telescopic arm 202, which can flexibly adjust the support span of the hinge frame 2 to adapt to projection lamps 5 of different lengths. The drive gear 206 in the first chamber 2041 meshes with the toothed plate 207 on the telescopic arm 202, which can realize the synchronous extension and retraction of the telescopic arms 202 on both sides, ensuring that the positions of the support plates 203 on both sides are symmetrical after adjustment, and preventing the projection lamp 5 from tilting after clamping.

[0019] Please see Figure 5 The connecting seat 204 has a second chamber 2042 at its top, and a drive wheel 209 is rotatably connected to the center of the second chamber 2042. Both sides of the second chamber 2042 have driven wheels 210 that mesh with the drive wheel 209. The centers of the two driven wheels 210 are connected to the center of the drive gear 206 below them via a rotating shaft. An adjustment knob 208 is installed at the center of the top of the connecting seat 204, and the output end of the adjustment knob 208 is connected to the center of the drive wheel 209. Rotating the adjustment knob 208 drives the drive wheel 209 to rotate, which in turn drives the driven wheels 210 on both sides to rotate synchronously. This, in turn, drives the drive gear 206 below to rotate via the rotating shaft, achieving synchronous adjustment of the telescopic arms 202 on both sides. This operation is convenient and the adjustment accuracy is high. The second chamber 2042 protects the drive wheel 209 and the driven wheels 210, preventing dust and impurities from entering and affecting the gear transmission effect, thus extending the service life of the components.

[0020] Please see Figure 2An integrated power terminal is provided on one side of the connecting base 204, and a telecommunications connection cable 7 is plugged into the integrated power terminal. The other end of the telecommunications connection cable 7 is provided with an anti-disconnect plug, which is compatible with the signal power slot of the projection lamp 5. An annular slip ring rotor 801 is coaxially embedded on the outer periphery of the turntable 8, and a conductive slip ring stator 6 is fixedly installed on the top of the base 1 on the outer side of the turntable 8 by a bracket. The conductive slip ring stator 6 and the slip ring rotor 801 are coaxially compatible and rotate together, and the contact surfaces of the two are provided with a wear-resistant conductive layer. The conductive slip ring stator 6 is connected to the battery via wires. Pool 10 and controller 12 are electrically connected. The slip ring rotor 801 is connected to the integrated power terminal on the connecting seat 204 through a flame-retardant wire of the same specification. The anti-detachment plug of the telecommunication connection cable 7 is adapted to the signal power slot of the projection lamp 5, which can prevent the connection cable from falling off when the projection lamp 5 rotates or moves, ensuring stable power supply and signal transmission. The conductive slip ring stator 6 is adapted to rotate coaxially with the slip ring rotor 801, which can keep the circuit continuously conductive when the turntable 8 drives the hinge frame 2 to rotate, avoiding the wire tangling. The integrated power terminal facilitates the quick connection of the telecommunication connection cable 7 and the connecting seat 204.

[0021] Please see Figure 4 and Figure 5 Each end of the telescopic sleeve 201 away from the connecting seat 204 is provided with a locking component 9. The locking component 9 includes a boss 901, an adjusting screw 902, a receiving groove 903, and a limiting prism 904. The boss 901 has a receiving groove 903 inside, and a limiting prism 904 that matches its shape is provided in the receiving groove 903. The upper surface of the telescopic arm 202 has a first prism groove 2021, and the bottom of the limiting prism 904 engages with the first prism groove 2021. An adjusting screw 902 is provided at the center of the top of the boss 901, and the output end of the adjusting screw 902 is rotatably connected to the limiting prism 904 for adjustment. The screw 902 can drive the limiting prism plate 904 to move up and down in the receiving groove 903. When the bottom of the limiting prism plate 904 engages with the first prism groove 2021 of the telescopic arm 202, it can firmly lock the position of the telescopic arm 202, preventing the telescopic arm 202 from sliding on its own when the equipment is working, thus ensuring the stability of the support structure. The shape of the receiving groove 903 matches that of the limiting prism plate 904, which can guide the movement direction of the limiting prism plate 904 and ensure that the limiting prism plate 904 is precisely engaged with the first prism groove 2021. The boss 901 provides an installation carrier for the adjusting screw 902 and the limiting prism plate 904, improving the firmness of the connection between the locking component 9 and the telescopic sleeve 201.

[0022] Please see Figure 4The rotary drive assembly 3 includes a mounting base 301, a worm gear 302, a worm 303, and a first servo motor 304. The mounting base 301 is welded to the top of the vertical plate of one of the "L"-shaped support plates 203, and the worm 303 is rotatably connected to the bottom of the mounting base 301. The worm gear 302 is provided in the mounting base 301 above the worm 303 and meshes with it. The worm gear 302 coincides with the central axis of the hinge plate 205. The first servo motor 304 is fixed on the mounting base 301 on one side of the worm 303, and the output end of the first servo motor 304 is connected to the worm 303 via a connection with the worm 303. 03 Connection: The first servo motor 304 drives the worm gear 303 to rotate, which in turn drives the worm wheel 302 to rotate, thereby driving the clamping and fixing assembly 4 and the projection lamp 5 to rotate. The servo motor has high driving precision, which can realize the precise adjustment of the angle of the projection lamp 5 to meet the complex lighting and shadow requirements of the stage. The meshing of the worm wheel 302 and the worm gear 303 has a self-locking function, which can prevent the projection lamp 5 from rotating on its own after being adjusted to the target angle, ensuring angle stability. The worm wheel 302 coincides with the central axis of the hinge plate 205, ensuring that the projection lamp 5 rotates around the fixed axis when rotating, avoiding deviation that affects the projection accuracy.

[0023] Please see Figure 2 and Figure 6The clamping and fixing assembly 4 includes a cross seat 401, a first extension arm 402, a second extension arm 403, and a movable clamping plate 405. The cross seat 401 has a cross-shaped structure. A second pull-out groove 4012 is formed along the length direction inside the horizontal part of the cross seat 401, and the second extension arm 403 is slidably fitted inside the second pull-out groove 4012. A first pull-out groove 4011 is formed along the height direction inside the upper half of the vertical part of the cross seat 401, and the first pull-out groove 4011 is located directly above the second pull-out groove 4012, with the two being vertically distributed. The first extension arm 402 is slidably fitted inside the first pull-out groove 4011. The first extension arm 402 and the second extension arm 403 are connected... 3. A movable clamping plate 405 is integrally connected to the end of the cross base 401 away from the center. The movable clamping plate 405 has a 90° bent structure, and its inner side forms a clamping surface adapted to the outer periphery of the projection lamp 5. A fixed clamping plate 4013 is integrally connected to the corresponding end of the cross base 401 away from the two movable clamping plates 405. The fixed clamping plate 4013 has a 90° bent structure. The bending direction of the fixed clamping plate 4013 is consistent with that of the corresponding movable clamping plate 405 and they are arranged opposite to each other. The fixed clamping plate 4013 and the movable clamping plate 405 together form a bidirectional clamping structure for the projection lamp 5. The side of the first extension arm 402 and the second extension arm 403 away from the connecting seat 204 is open. A second ribbed groove 404 is provided, and the second ribbed grooves 404 are evenly spaced along the length direction of the first extension arm 402 and the second extension arm 403. A locking component 9 is fixed to the outer side of the cross seat 401 away from the fixed clamping plate 4013, and the limiting ribbed plate 904 of the locking component 9 engages with the corresponding second ribbed groove 404 to lock the pull-out position of the first extension arm 402 and the second extension arm 403. The first pull-out groove 4011 and the second pull-out groove 4012 of the cross seat 401 are respectively adapted to the first extension arm 402 and the second extension arm 403. The distance between the movable clamping plate 405 and the fixed clamping plate 4013 can be adjusted by pulling out the extension arms. The projector lamps 5 of different diameters and sizes are highly compatible. Both the movable clamping plate 405 and the fixed clamping plate 4013 have a 90° bending structure, which can increase the contact area with the projector lamps 5, improve clamping stability, and prevent the projector lamps 5 from slipping. The second rib grooves 404 on the first extension arm 402 and the second extension arm 403 are matched with the limiting rib plate 904 of the locking component 9, which can quickly lock the position of the extension arm and ensure that the movable clamping plate 405 is fixed after clamping. The operation is convenient and the fixation is reliable. The cross-shaped seat 401 can form a two-way clamping of the projector lamps 5 from the horizontal and vertical directions, further improving the clamping stability and ensuring that the projector lamps 5 do not deviate during rotation and projection.
