DETAILED DESCRIPTION

[0036] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] Reference Figure 1-8 The deformable stage lamp includes a first base 100 and a second base 200. The first base 100 and the second base 200 are both cube structures with the same length, width and height. The top surfaces of the first base 100 and the second base 200 are both equipped with a lamp body 230.

[0041] Two first rotating drums 110 are disposed in a corner of the first base 100. The two first rotating drums 110 are located at the top and bottom of the first base 100, and are aligned with the top and bottom surfaces of the first base 100 on opposite sides of the axis. A first rotating shaft 120 is provided through the two first rotating drums, and the ends of the first rotating shaft 120 are rotatably connected to the opposite sides of the two first rotating drums 110 on the axis.

[0042] The first base 100 is mounted on a drive unit, which includes a drive motor 300, a first gear 310, a second rotating shaft 320, and a second gear 330. The first gear 310 is mounted on the first rotating shaft 120 and is located within the top first rotating drum 110. The second rotating shaft 320 is rotatably mounted within the first base 100, and the second gear 330 is mounted on the second rotating shaft 320. The first gear 310 and the second gear 330 are meshed and connected to each other, and the second gear 330 has more teeth than the first gear 310. The output end of the drive motor 300 is connected to the second rotating shaft 320 or connected to the second rotating shaft 320 via a coupling. This allows the drive motor 300 to rotate the second rotating shaft 320, thereby driving the second gear 330. The rotation of the second gear 330 drives the first gear 310, which in turn drives the first rotating shaft 120.

[0043] A second rotating drum 210 is disposed in a corner of the second base 200. The second rotating drum 210 is located in the middle of the second base 200. The distance between the two first rotating drums 110 on their adjacent sides is equal to the height of the second rotating drum 210, allowing the second rotating drum 210 to be inserted between the two first rotating drums 110. It will be understood that the outer diameters of the first and second rotating drums 110, 210, are the same, and the first rotating drum 110, the second rotating drum 210, and the first rotating drum 110 at the top and the bottom are stacked in this order.

[0044] Among them, a connected wiring ring groove 220 is opened at the bottom of the second rotating drum 210 and the top of the first rotating drum 110 at the bottom. A channel for the conductive wire 221 to pass through is formed between the side wall of the wiring ring groove 220 and the first rotating shaft 120, thereby ensuring that the conductive wire 221 will not hinder the relative rotation between the first base 100 and the second base 200.

[0045] The first rotating shaft 120 is provided on the second rotating drum 210 and is fixedly connected to the top of the second rotating drum 210, so that when the first rotating shaft 120 rotates, it can drive the second base 200 to rotate relative to the first base 100, thereby realizing the orientation change between two adjacent lamp bodies 230.

[0046] For example, refer to Figure 9-11 When the stage light as a whole includes four bases, the four bases can change their positions by relative rotation, thereby changing the orientation of the four lamp bodies and providing different lighting effects for the stage.

[0047] Reference Figure 1-8 A chain 500 is disposed between the first base 100 and the second base 200. The chain 500 is formed by a plurality of chain blocks 510 rotatably connected. Two third rotating shafts 600 are rotatably mounted on the first base 100, one on either side of the first rotating drum 110. Two fourth rotating shafts 610 are rotatably mounted on the second base 200, one on either side of the second rotating drum 210. The chain blocks 510 at one end, or the extreme end of the chain 500, are rotatably mounted on the sidewall of one of the fourth rotating shafts 610. The chain blocks 510 at the other end, or the extreme end of the chain 500, are rotatably mounted on the sidewall of the other fourth rotating shaft 610 after passing through the two third rotating shafts 600. It will be appreciated that both sidewalls of the first base 100 adjacent to the first rotating drum 110 are provided with notches 620 for the chain 500 to pass through. Two side walls of the second base 200 adjacent to the second rotating drum 210 are both provided with holes for the chain 500 to pass through.

[0048] When the second base 200 rotates relative to the first base 100, the relative connection relationship between the first base 100 and the second base 200 can be guaranteed due to the pulling of the chain 500. Even if the first rotating shaft 120 is damaged, the first base 100 and the second base 200 are connected by the chain 500, thereby preventing the first base 100 or the second base 200 from being thrown out or falling off.

[0049] Furthermore, a cam 400 is mounted on the second rotating shaft 320. The outer periphery of the cam 400 contacts the side of the chain 500 near the third rotating shaft 600. The outer periphery of the cam 400 has a special curve. When the drive motor 300 drives the second base 200 to rotate relative to the first base 100, the second rotating shaft 320 also drives the cam 400 to rotate, thereby keeping the chain 500 in a taut state. When the chain 500 is in a taut state, it can tighten the first base 100 and the second base 200, making their relative movement smoother and their relative position more stable, thereby ensuring the stability and aesthetics of the lighting effects displayed by the two lamp bodies 230.

[0050] A first magnetic block 630 and a second magnetic block 640 are installed near the notch 620 of the first base 100, and each notch 620 is provided with two first magnetic blocks 630 and two second magnetic blocks 640. The two first magnetic blocks 630 are respectively located at the top and bottom of the notch 620, and the two second magnetic blocks 640 are also respectively located at the top and bottom of the notch 620. That is, a first magnetic block 630 and a second magnetic block 640 are respectively provided at the top and bottom of the notch 620, and the first magnetic blocks 630 and the second magnetic blocks 640 are arranged side by side.

[0051] A fifth rotating shaft 520 is provided between two adjacent chain blocks 510. The fifth rotating shaft 520 comprises a non-circular segment 522 and a circular segment 521. The circular segment 521 has a circular cross-section, while the non-circular segment 522 has a non-circular cross-section, such as a square, pentagon, hexagon, or triangle. The holes in the chain blocks 510 through which the fifth rotating shaft 520 passes include a circular hole 511 and a non-circular hole 512. The circular hole 511 mates with the circular segment 521, while the non-circular hole 512 mates with the non-circular segment 522. Third magnetic blocks with opposite magnetic properties are located at each end of the fifth rotating shaft 520.

[0052] When the second base 200 swings relative to the first base 100, the chain block 510 on one side of the chain 500 extends out of the first base 100 from the notch 620 of the first base 100. At this time, the two adjacent chain blocks 510 pass through the first magnetic block 630 and the second magnetic block 640 in sequence when passing through the notch 620. When the fifth rotating shaft 520 between the two adjacent chain blocks 510 passes through the second magnetic block 640, the second magnetic block 640 interacts with the third magnetic block 650 at the end of the fifth rotating shaft 520 on the same side to make the fifth rotating shaft 520 slide, so that the non-circular segments 522 of the fifth rotating shaft 520 are all inserted into the non-circular holes 512 of the two adjacent chain blocks 510, even if the two adjacent chain blocks 510 cannot rotate relative to each other. Therefore, the chain 500 extending out of the first base 100 maintains an overall stable state because the two adjacent chain blocks 510 cannot rotate, thereby providing a larger supporting force between the first base 100 and the second base 200, ensuring the relative position stability of the first base 100 and the second base 200.

[0053] When the second base 200 swings relative to the first base 100, the chain block 510 on the other side of the chain 500 will extend into the first base 100 through the notch 620 of the first base 100. At this time, the two adjacent chain blocks 510 will pass through the second magnetic block 640 and the first magnetic block 630 in sequence when passing through the notch 620. When the fifth rotating shaft 520 between the two adjacent chain blocks 510 passes through the first magnetic block 630, the first magnetic block 630 interacts with the third magnetic block 650 at the end of the fifth rotating shaft 520 on the same side to cause the fifth rotating shaft 520 to slide, thereby causing the non-circular segment 522 of the fifth rotating shaft 520 to extend out of the non-circular hole 512 of one of the chain blocks 510, so that the two adjacent chain blocks 510 can rotate relative to each other around the axis of the fifth rotating shaft 520 again, thereby ensuring the bendable and directional change ability of the chain 500 in the first base 100.

[0054] For example, the first magnetic block 630 has an N pole, the second magnetic block 640 has an S pole, the third magnetic block 650 at the top of the fifth rotating shaft 520 has an S pole, and the third magnetic block 650 at the bottom of the fifth rotating shaft 520 has an N pole. The N poles and S poles attract each other, while the N poles and the S poles repel each other. When the fifth rotating shaft 520 extends out of the first base 100, the repulsive force between the upper second magnetic block 640 and the top third magnetic block 650, and the attractive force between the lower second magnetic block 640 and the bottom third magnetic block 650, causes the fifth rotating shaft 520 to quickly respond and slide downward, thereby allowing the non-circular segments 522 of the fifth rotating shaft 520 to be inserted into the non-circular holes 512 of the two adjacent chain blocks 510, even if the two adjacent chain blocks 510 cannot rotate relative to each other. When the fifth rotating shaft 520 extends into the first base 100, the mutual attraction between the upper first magnetic block 630 and the top third magnetic block 650, and the mutual repulsion between the lower first magnetic block 630 and the bottom third magnetic block 650, enable the fifth rotating shaft 520 to quickly respond and slide upward. The non-circular segment 522 of the fifth rotating shaft 520 extends out of the non-circular hole 512 of one of the chain blocks 510, thereby allowing the two adjacent chain blocks 510 to rotate relative to each other around the axis of the fifth rotating shaft 520. It will be appreciated that the second magnetic block 640 is located closer to the outside of the first base 100.

[0055] It should be noted that due to the presence of the first rotating drum 110 and the second rotating drum 210, when the first base 100 and the second base 200 are in close contact, the fifth rotating shaft 520 of the chain 500 corresponding to the center of rotation can be provided without the non-circular section 522, allowing the chain 500 to rotate a certain angle at this position to prevent interference between the second rotating drum 210 and the chain. In another embodiment, a groove structure for the chain 500 to be inserted can be provided on the outer circumference of the first rotating drum 110 and the second rotating drum 210, and the first magnetic block 630 and the second magnetic block 640 are mounted side by side on the upper and lower surfaces of the groove structure. When the first base 100 and one side of the second base 200 are in close contact, the fifth rotating shaft 520 at the corresponding rotation center position in the external chain 500 passes through the second magnetic block 640 and the first magnetic block 630 in sequence. Under the interaction of the first magnetic block 630 and the third magnetic block 650, the fifth rotating shaft 520 can respond quickly and slide upward, and the non-circular segment 522 of the fifth rotating shaft 520 extends out of the non-circular hole 512 of one of the chain blocks 510, so that the corresponding two chain blocks 510 can rotate relative to each other around the axis of the fifth rotating shaft 520 again. To prevent the second rotating drum 210 from interfering with the chain and being unable to rotate into place, similarly, when the first base 100 and the second base 200 are rotated apart from each other from a state of being tightly attached on one side, under the action of the second magnetic block 640, the fifth rotating shaft 520 can respond quickly and slide downward, so that the non-circular segments 522 of the fifth rotating shaft 520 are inserted into the non-circular holes 512 of the corresponding two chain blocks 510, even if the two adjacent chain blocks 510 cannot rotate relative to each other, the linear support capacity and anti-deformation capacity of the chain 500 are maintained.

[0056] Furthermore, to ensure the positional stability of the fifth rotating shaft 520, positioning grooves 700 are transversely defined at both the top and bottom of the chain block 510. Springs 710 are housed within the positioning grooves 700, one end of which is secured to the bottom wall of the positioning groove 700, while a positioning bead 720 is fixedly mounted to the other end. Positioning holes 730 are provided at both ends of the fifth rotating shaft 520. These annular positioning holes 730 mate with the positioning bead 720. When the fifth rotating shaft 520 slides upward until its top surface is flush with the top surface of the chain block 510, the corresponding springs 710 cause the positioning bead 720 at the top to engage with the positioning hole 730 at the top, thereby restricting the position of the fifth rotating shaft 520 and maintaining its stability in the upper position. When the fifth rotating shaft 520 slides downward until the bottom surface is just flush with the bottom surface of the chain block 510, under the action of the corresponding spring 710, the positioning bead 720 at the bottom abuts against the positioning hole 730 at the bottom, thereby limiting the position of the fifth rotating shaft 520 and maintaining the stability of the fifth rotating shaft 520 in the lower position.

[0057] Reference Figure 12-13The two ends of the chain block 510 away from the side of the third rotating shaft 600 are provided with right-angle limiting blocks 740 protruding therefrom. The right-angle limiting blocks 740 are triangular structures with right-angle edges, so that the two adjacent chain blocks 510 can only rotate towards the direction of wrapping the third rotating shaft 600, thereby improving the compression resistance of the chain 500 part extending out of the first base 100, further improving the connection strength of the chain, and further improving the relative connection stability between the first base 100 and the second base 200.

[0058] Further, with reference to Figure 14-15 The stage lamp further comprises a first mounting plate 800. The first base 100 is provided with a sixth rotating shaft 810. The top of the sixth rotating shaft 810 penetrates the top of the first base 100 and is mounted on the top of the first base 100 through a flange, and the bottom of the sixth rotating shaft 810 penetrates the bottom of the first base 100 and is provided with a roller 830. The second base 200 is provided with a seventh rotating shaft 820. The top of the seventh rotating shaft 820 penetrates the top of the first base 100 and is mounted on the top of the first base 100 through a flange, and the bottom of the sixth rotating shaft 810 penetrates the bottom of the first base 100 and is provided with a roller 830. The top and bottom circumferential sides of the roller 830 are annularly provided with a plurality of balls 840, and the balls 840 partially protrude from the top surface or the bottom surface of the roller 830 and can roll relative to the roller 830. The first base 100 is provided with two sixth rotating shafts 810, and the distance between the two sixth rotating shafts 810 from the first rotating shaft 120 is different. The second base 200 is provided with two seventh rotating shafts 820, and the distance between the two seventh rotating shafts 820 from the first rotating shaft 120 is different.

[0059] The top of the first mounting plate 800 is provided with four T-shaped grooves 850, which are arc-shaped grooves curved in a circular arc shape with the axis of the first rotating shaft 120. The four T-shaped grooves 850 can correspondingly slide the rollers 830 at the bottom of the two sixth rotating shafts 810 and the two seventh rotating shafts 820, respectively. One end of each of the four T-shaped grooves 850 penetrates one side of the first mounting plate 800. When the roller 830 slides in the corresponding T-shaped groove 850, the balls 840 abut against the top surface and the bottom surface of the head of the T-shaped groove 850, thereby ensuring smooth sliding of the roller 830 in the T-shaped groove 850.

[0060] The first mounting plate 800 is slidingly provided with a clamping frame 860. The clamping frame 860 has four end portions, and each end portion is provided with a limiting groove 870. The openings of the limiting grooves 870 are oppositely distributed. The top of the first mounting plate 800 is further provided with a first telescopic cylinder 880, which is a pneumatic cylinder, a hydraulic cylinder or an electric telescopic cylinder. The output end of the first telescopic cylinder 880 is connected with the clamping frame 860.

[0061] When the first telescopic cylinder 880 drives the bracket 860 to slide to one end, the two sixth rotating shafts 810 of the first base 100 can be respectively embedded in the two limiting grooves 870 on the same side, thereby limiting the sliding of the sixth rotating shafts 810 in the corresponding T-slots 850, making it impossible for the first base 100 to rotate relative to the first mounting plate 800. Therefore, if the drive motor 300 is started at this time to drive the second base 200 to rotate relative to the first base 100, the second base 200 can be rotated relative to the first mounting plate 800, while the first base 100 is fixed relative to the first mounting plate 800.

[0062] When the first telescopic cylinder 880 drives the bracket 860 to slide to the other end, the two seventh rotating shafts 820 of the second base 200 are respectively embedded in the two limiting grooves 870 on the other side, thereby restricting the sliding of the seventh rotating shafts 820 within the corresponding T-slots 850 and preventing the second base 200 from rotating relative to the first mounting plate 800. Therefore, if the drive motor 300 is activated to rotate the second base 200 relative to the first base 100 at this time, the first base 100 can rotate relative to the first mounting plate 800, while the second base 200 remains stationary relative to the first mounting plate 800. Therefore, the first telescopic cylinder 880 can be driven to restrict the first base 100 or the second base 200 according to the desired stage lighting effect.

[0063] Example 2:

[0064] Reference Figure 16-19 The difference between the embodiment of the present application and the first embodiment is that the mounting structures of the first base 100 and the second base 200 are different. In this embodiment, the stage light further includes a second mounting plate 900, which replaces the first mounting plate 800.

[0065] Specifically, the top of the second mounting plate 900 defines two annular grooves 910 of varying radii. The annular grooves 910 have a T-shaped cross-section, allowing the rollers 830 to slide within them. Each opening of the annular grooves 910 accommodates the sliding movement of a sixth rotating shaft 810 and a seventh rotating shaft 820, respectively. The balls 840 on the rollers 830 contact the top or bottom surfaces of the T-shaped heads of the annular grooves 910, ensuring smooth sliding of the first base 100 and the second base 200, respectively, relative to the second mounting plate 900.

[0066] A connecting cylinder 930 is rotatably mounted in the middle of the first rotating shaft 120. The bottom of the connecting cylinder 930 extends out of the first base 100 and is inserted into the top of the second mounting plate 900. The bottom of the connecting cylinder 930 is fixedly connected to the second mounting plate 900.

[0067] A second telescopic cylinder 940 is mounted on top of the connecting tube 930, positioning the second telescopic cylinder 940 at the top of the first base 100, thereby reducing the overall height of the structure. The second telescopic cylinder 940 can be a pneumatic, hydraulic, or electric cylinder. The top of the connecting tube 930 extends out of the first base 100 and connects to the housing of the second telescopic cylinder 940. The output end of the second telescopic cylinder 940 extends into the connecting tube 930 and can slide along its axis relative to the connecting tube 930. The connecting tube 930 also provides support for the rotation of the first rotating shaft 120 relative to the first base 100.

[0068] A fixed rod 920 is fixedly mounted on the outside of the seventh rotating shaft 820. The end of the fixed rod 920, away from the seventh rotating shaft 820, faces directly toward the first rotating shaft 120 and is then sleeved onto the outside of the connecting tube 930. The fixed rod 920 is rotatable relative to the connecting tube 930. Two first push rods 950 and two second push rods 970 are rotatably mounted on the output end of the second telescopic cylinder 940. A first push block 960 is rotatably mounted on the end of the first push rod 950 away from the output end of the second telescopic cylinder 940. The first push block 960 slides through the connecting tube 930. A second push block 980 is rotatably mounted on the end of the second push rod 970 away from the output end of the second telescopic cylinder 940. The second push block 980 slides through the connecting tube 930.

[0069] The two first push blocks 960 are symmetrically located on either side of the output end of the second telescopic cylinder 940. The two second push blocks 980 are also symmetrically located on either side of the output end of the second telescopic cylinder 940. The opposite sides of the two first push blocks 960 correspond to the bottom of the first base 100, and the opposite sides of the two second push blocks 980 correspond to the fixed rod 920.

[0070] Therefore, when the output end of the second telescopic cylinder 940 is located in the middle position between the first base 100 and the fixing rod 920 , the two first push blocks 960 and the two second push blocks 980 do not protrude from the outer wall of the connecting tube 930 .

[0071] When the output end of the second telescopic cylinder 940 is driven to move downward, the second push block 980 is pushed out of the outer wall of the connecting tube 930 and pressed against the fixing rod 920 through the second push rod 970, thereby limiting the rotation of the fixing rod 920 relative to the second mounting plate 900, that is, limiting the rotation of the second base 200 relative to the second mounting plate 900. Therefore, if the drive motor 300 is started at this time to drive the second base 200 to rotate relative to the first base 100, the first base 100 can be rotated relative to the first mounting plate 800, while the second base 200 is fixed relative to the first mounting plate 800.

[0072] When the output end of the second telescopic cylinder 940 is driven to move upward, the first push block 960 will be pushed out of the outer wall of the connecting cylinder 930 by the first push rod 950 and abut against the bottom position of the first base 100, thereby limiting the rotation of the first base 100 relative to the second mounting plate 900. Therefore, if the driving motor 300 is started to drive the second base 200 to rotate relative to the first base 100 at this time, the second base 200 can be rotated relative to the second mounting plate 900, while the first base 100 is fixed relative to the second mounting plate 900. Therefore, the second telescopic cylinder 940 can be driven to limit the first base 100 or the second base 200 according to the required lighting effect of the stage.

[0073] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
