Description

Technical Field

[0001] The present application relates to the technical field of shadow play, and in particular to a shadow play display device and a control method thereof. Background Art

[0002] As a traditional art with local characteristics in my country, shadow puppetry not only contains the essence of traditional Chinese art, but is also a mysterious artistic skill. Ordinary people rarely have the opportunity to directly contact shadow puppetry in life. At the same time, shadow puppetry has high requirements for the skills of performers. In addition to being able to control the movements of the shadow figures, performers must also closely cooperate with the background music, taking into account the narration and singing. It is not easy to master a solid foundation in shadow puppet performance. Therefore, the dissemination and inheritance of shadow puppetry are also restricted by the difficulty of shadow puppetry performance. By combining mechanical automation control technology and devices to perform shadow puppetry, it can play a positive role in the dissemination of shadow puppetry performances and the inheritance of skills. Researchers have also successively developed a variety of devices for displaying shadow puppetry performances. The structure can refer to a shape-matching robot for shadow puppetry performances disclosed in Chinese patent document CN114534275B. It includes a linear module and a shadow puppet robot arranged thereon. The shadow puppet robot is connected to three control lines of a shadow puppet. The linear module controls the horizontal movement of the robot and controls the movements of the shadow puppet through the robot. The shadow puppet robot controls various movements of the shadow puppet through a contour-like torso and two contour-like arms, thereby realizing a shadow puppet performance display.

[0003] In the above structure, since the copying trunk is connected to the copying arm, when the copying trunk is rotating, the copying arm will be affected by the rotation of the copying trunk and tilt, which will cause the various parts of the shadow puppet to be difficult to be in the same vertical plane during movement, and there will be a large gap between the overall fit of the shadow puppet and the screen, which will affect the imaging of the shadow puppet on the screen. Therefore, when the copying arm controls the swing or bending of the shadow puppet's hand parts, it is necessary to control the copying trunk to rotate at the same time to ensure that the shadow puppet as a whole is in the same vertical plane; and the rotation of the copying trunk will affect the swing of the shadow puppet's head parts, so it is difficult to control the individual parts of the shadow puppet to move independently, affecting the performance of the shadow puppet.

[0004] Therefore, there is a need for a shadow play display device and a control method thereof that can reliably image shadow puppets and is convenient for controlling individual parts of the shadow puppets to move independently. Summary of the invention

[0053] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0054] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0055] Reference Figure 1-5 , a shadow play display device, comprising: a frame body 1, a curtain 7 and a shadow play lamp 8;

[0056] The frame body 1 includes twelve metal rods and a rectangular frame defined by the metal rods. The metal rods are made of aluminum alloy profiles. The curtain 7 is arranged on the front side of the frame body 1. The shadow puppet lamp 8 is fixedly arranged on the frame body 1 to project the shadow puppet onto the curtain 7.

[0057] In some embodiments, the shadow play display device further includes: a moving mechanism 2 and a control mechanism consisting of three connecting rods 3, three telescopic rods 301 and three first motors;

[0058] Specifically, the moving mechanism 2 is arranged in the frame body 1, and is used to adjust the position of the shadow puppet in the frame body 1 to change the projection form; the ends of the three connecting rods 3 close to the screen 7 are respectively hinged to the head part and the hand part of the shadow puppet through universal joints to control the movement of the shadow puppet; and the ends of the three connecting rods 3 close to the screen 7 are in the same plane parallel to the screen 7; the ends of the three telescopic rods 301 away from the hinge point of the shadow puppet part are respectively hinged to the ends of the three connecting rods 3 away from the screen 7 through universal joints, and the telescopic rods 301 are respectively connected to the ends of the three connecting rods 3 away from the screen 7 through universal joints. The rod 301 is arranged parallel to the curtain 7; three first motors 302 are fixedly arranged on the moving mechanism 2 by bolts, the rotating end of the first motor 302 is vertically connected with a first connecting piece via a key body, the first connecting piece is fixedly connected with a hinge seat by welding, one end of the telescopic rod 301 close to the hinge point of the shadow puppet part is hinged in the hinge seat, the three telescopic rods 301 are respectively connected to the rotating ends of the three first motors 302 through the first connecting piece and the hinge seat, and the rotating ends of the first motors 302 are respectively coaxially arranged with the hinge points of the shadow puppet part;

[0059] More specifically, the three first motors 302 are used to independently control the swing of the head part and the hand part of the shadow puppet. When the first motor 302 rotates, it drives the telescopic rod 301 to rotate. When the joints of the hand parts of the shadow puppet are relatively fixed, the telescopic rod 301 is in a fixed limit position. At this time, the hand parts of the shadow puppet can be regarded as a whole; the telescopic rod 301 drives the connecting rod 3 to rotate axially around the rotating end of the first motor 302, so the head part or the hand part of the shadow puppet can be swung around the hinge point by the first motor 302. At this time, the body part of the shadow puppet is relatively still, and the movement of the head part or the hand part of the shadow puppet does not affect the movement of other parts of the shadow puppet. In this way, the movement of the head part or the hand part of the shadow puppet can be independently controlled, which is convenient for simplifying the control logic. At the same time, it can be understood that since the length of the telescopic rod 301 depends on the distance from the hinge point of each part of the shadow puppet to the end of the end that is hinged with the connecting rod 3, and the head part of the shadow puppet usually does not need to bend, but only needs to swing, when used to control the swing of the head part of the shadow puppet, the telescopic rod 301 can be replaced with a rod of fixed length, which does not affect the use of this embodiment.

[0060] More specifically, the telescopic rod 301 is used to control the bending of the shadow puppet's hand. When the shadow puppet's hand part needs to be bent, the rotating end of the first motor 302 slightly rotates in the bending direction of the hand part, and the telescopic rod 301 contracts, so that the shadow puppet's hand part can be bent. The bending of the shadow puppet's two hand parts does not affect the movement of other parts of the shadow puppet, so the movement of the shadow puppet's two hand parts can be independently controlled, which is convenient for simplifying the control logic.

[0061] In some embodiments, the moving mechanism 2 includes: a longitudinal moving assembly consisting of a second motor 4, a first synchronous belt 401, a first transmission shaft 402, a second synchronous belt 403, a first moving block 404, a first guide rod 405 and a first slider 406, for realizing longitudinal movement of the shadow puppet;

[0062] Specifically, the second motor 4 is fixedly arranged on the rear side of the frame body 1 by bolts, and is used to drive the longitudinal movement of the moving mechanism 2. The rotating end of the second motor 4 is connected to the first synchronous pulley; the first synchronous belt 401 is vertically arranged on the rear side of the frame body 1 and is arranged at the lower part of the second motor 401, and the upper end of the first synchronous belt 401 is connected to the first synchronous pulley; the first transmission shaft 402 is transversely arranged on the rear side of the frame body 1 through a pair of bearing seats, and is arranged at the lower part of the second motor 401, and the middle part of the first transmission shaft 402 is provided with a second synchronous pulley, the lower end of the first synchronous belt 401 is connected to the second synchronous pulley, the first transmission shaft 402 is rotated by the transmission of the first synchronous belt 401, and the two ends of the first transmission shaft 402 are provided with third synchronous pulleys; the second synchronous belt 403 is longitudinally arranged on both sides of the frame body 1, and one end of the second synchronous belt 403 close to the rear side of the frame body 1 is connected to the third synchronous pulley; the front side of the frame body 1 is provided with a pair of bearing seats The second transmission shaft, both ends of the second transmission shaft are provided with fourth synchronous pulleys, and one end of the second synchronous belt 403 near the front side of the frame body 1 is connected to the fourth synchronous pulley; the reciprocating rotation of the rotating end of the second motor 4 drives the first synchronous belt 401 to drive, the transmission of the first synchronous belt 401 drives the first transmission shaft 402 to rotate, and the rotation of the first transmission shaft 402 drives the reciprocating transmission of the second synchronous belt 403 in the longitudinal direction; the first moving block 404 is fixedly arranged on the second synchronous belt 403 by bolts, and moves longitudinally following the transmission of the second synchronous belt 403; the first guide rod 405 is longitudinally arranged on both sides of the frame body 1 through a coupling, and is arranged above the second synchronous belt 403; the first slider 406 is slidably sleeved on the first guide rod 405, and is connected to the upper part of the first moving block 404 by bolts, and the first slider 406 moves longitudinally following the movement of the first moving block 404, and the first guide rod 405 can guide and stabilize the movement of the first slider 406. The longitudinal moving component thus realizes the longitudinal movement of the shadow puppet.

[0063] In some embodiments, the moving mechanism 2 further includes: a lateral moving assembly consisting of a transverse plate 5, a third motor 501, a fifth synchronous pulley 502, a third synchronous belt 503, a sixth synchronous pulley 504, a second moving block 505, a second guide rod 506 and a second slider 507, for realizing lateral movement of the shadow puppet;

[0064] Specifically, the two ends of the horizontal plate 5 are fixed on the first slider 406 by bolts, and move longitudinally following the movement of the first slider 406; in addition, a control circuit board, a power supply, an air pump and an audio system can also be set on the horizontal plate 501; the third motor 501 is fixed on the lower part of the horizontal plate 5 by bolts, and is used to drive the lateral movement of the mobile mechanism 2; the fifth synchronous pulley 502 is set on the third motor 501 and is connected to the rotating end of the third motor 501; the third synchronous belt 503 is horizontally set at the lower part of the horizontal plate 5, and is connected to the fifth synchronous pulley 502 at one end close to the third motor 501; the sixth synchronous pulley 504 is set at the lower part of the horizontal plate 5 through a bearing rotation connection, and is connected to the end of the third synchronous belt 503 away from the third motor 501; in this way, the third motor The reciprocating rotation of the rotating end of the machine 501 drives the fifth synchronous pulley 502 to rotate, and the rotation of the fifth synchronous pulley 502 drives the third synchronous belt 503 to reciprocate in the transverse direction; the second moving block 505 is fixedly arranged on the third synchronous belt 503 by bolts, and moves transversely following the third synchronous belt 503; the second guide rod 506 is transversely fixedly arranged below the transverse plate 5 through a coupling, and is arranged above the third synchronous belt 503; the second slider 507 is slidably sleeved on the second guide rod 506, and the second guide rod 506 can guide and stabilize the movement of the second slider 507, and the lower part of the second slider 507 is fixedly connected to the second moving block 505 by bolts; the second slider 507 moves transversely following the movement of the second moving block 505. The transverse moving assembly thus realizes the transverse movement of the shadow puppet.

[0065] In some embodiments, the moving mechanism 2 further includes: a vertical moving assembly consisting of a slot plate 6, a cylinder 601 and a connecting plate 602, for realizing vertical movement of the shadow puppet;

[0066] Specifically, the slot plate 6 is fixedly arranged on the side of the second slider 507 by bolts, and moves laterally following the movement of the second slider 507; the cylinder 601 is fixedly arranged in the slot plate 6 by bolts, and the vertical movement of the three first motors 302 is realized by the extension and contraction of the moving end of the cylinder 601 in the vertical direction; the connecting plate 602 is fixedly arranged on the moving end of the cylinder 601 by bolts, and the above-mentioned first motor 302 is fixedly arranged on the connecting plate 602 by bolts. The vertical movement assembly realizes the vertical movement of the shadow puppet.

[0067] The control method of the shadow play display device implemented according to the above embodiment includes the following steps:

[0068] S1: Turn on the shadow puppet lamp 8; move the position of the shadow puppet by the moving mechanism 2 until the shadow puppet contacts the inner side of the curtain 7, and then adjust the position of the shadow puppet on the curtain 7 so that the shadow puppet is completely visible on the curtain 7;

[0069] S2: The shadow puppet part is swung by the rotation of the first motor 303; the shadow puppet part is swung and bent by the rotation of the first motor 303 and the extension and retraction of the telescopic rod 302;

[0070] S3: The shadow play performance is realized by moving the moving mechanism 2 in combination with the movement of the shadow play parts.

[0071] To summarize, the present invention can move the position of the shadow puppet through the moving mechanism 2. When the first motor 302 of the control mechanism 3 rotates, it drives the telescopic rod 301 to rotate, and the telescopic rod 301 drives the connecting rod 3 to rotate around the axial direction of the rotating end of the first motor 302. Therefore, the head of the shadow puppet can be rotated around the hinge point in the vertical plane through the rotation of the first motor 302, so that the shadow puppet's head can swing. At this time, the body of the shadow puppet is relatively still, and the movement of the shadow puppet's head does not affect the movement of other parts of the shadow puppet. In this way, the movement of the shadow puppet's head can be controlled separately, simplifying the control logic; when the shadow puppet's arm needs to be bent, the first motor 302 rotates slightly in the direction of the arm bending, and the telescopic rod 301 contracts at the same time, so that the shadow puppet's arm can swing and bend; the present invention can independently control the movement of the shadow puppet's head and two arms, and the control logic is simple; the ends of the three connecting rods 3 connected to the shadow puppet are in the same vertical plane, so that the shadow puppet as a whole is always in the same vertical plane, and the imaging of the shadow puppet is reliable.
