[0067] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0069] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0070] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0071] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0072] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0073] like Figures 1 to 4 As shown, the embodiment of the present application discloses a performance device, including a winding device 1, two lifting components 2 and a display device 4; wherein the winding device 1 has a traction member 11, and the winding device 1 can be used to retract and release the traction member 11; the lifting component 2 includes a fixed bracket 21 and at least one lifting bracket 22, the traction member 11 is drawn out from the winding device 1, wound on the fixed bracket 21, and then wound and fixed on the lifting bracket 22, and the winding device 1 retracts and releases the traction member 11 so that the lifting bracket 22 rises or falls relative to the fixed bracket 21. For example, the lifting bracket 22 can be completely accommodated in the fixed bracket 21 when the winding device 1 releases the traction member 11 to realize the descent of the display device 4, or the lifting bracket 22 can pull the lifting bracket 22 up when the winding device 1 retracts the traction member 11 to make the display device 4 rise. In summary, the embodiment of the present application drives the lifting bracket 22 to rise or fall by releasing or retracting the traction member 11 of the winding device 1, thereby making the display device 4 rise or fall, so as to ensure that the display device 4 is relatively stable and reliable to rise and fall.

[0074] Specifically, the winding device 1 of this embodiment can be, for example, a common winch in the related art, which can realize the clockwise or counterclockwise winding of the traction member 11 therein through electric control, thereby realizing the release or retraction of the traction member 11. Optionally, the traction member 11 is a metal traction rope or a metal traction chain; for example, it can be a steel wire rope, or a chain, etc., which is selected according to actual needs, and this embodiment does not make specific restrictions on this. In addition, the display device 4 can be, for example, Figure 1 The circle shown may also be a square or any other shape, which is selected according to actual needs and is not specifically limited in this embodiment.

[0075] Since the display device 4 is relatively large in size and mass, and in order to make the lifting of the display device 4 more stable, the lifting components 2 of this embodiment can be arranged as two opposite ones, and the two lifting components 2 are lifted and lowered together to drive the display device 4 to be lifted and lowered more stably. Each lifting component 2 includes a fixed bracket 21 and at least one lifting bracket 22, and the fixed bracket 21 is arranged on the support surface, that is, the fixed bracket 21 is immovable relative to the support surface, and only the lifting bracket 22 is lifted and lowered relative to the fixed bracket 21 or the support surface to drive the display device 4 to be lifted and lowered. Therefore, the fixed bracket 21 can be arranged on a support surface such as the ground, so that the lifting bracket 22 can be accommodated in the fixed bracket 21 and can be lifted and lowered relative to the fixed bracket 21.

[0076] For example, when there is no need to raise the display device 4, the lifting bracket 22 is accommodated in the fixed bracket 21. At this time, the display device 4 is flush with the performance device, and the display device 4 can serve as a part of the performance device for performers to stand and perform the performance device; when it is necessary to raise the display device 4 to present image information to the audience, the lifting bracket 22 is raised relative to the fixed bracket 21 and drives the display device 4 to rise to a predetermined height.

[0077] It should be explained here that the height of the display device 4 relative to the performance device must be at least greater than the radius of the display device 4 to ensure that the display device 4 can be turned over with its radius as the radius when it is raised to the preset height for the audience to watch. The specific height of the display device 4 relative to the performance device is set according to actual needs, and this embodiment does not specifically limit this.

[0078] In this embodiment, if Figures 1 to 3 As shown, the specific lifting process of the lifting component 2 is as follows:

[0079] The traction member 11 is led out from the winding device 1, wound on the fixed bracket 21, and then wound and fixed on the lifting bracket 22; in a feasible manner of this embodiment, for Figure 1 The lifting assembly 2 on the left is used as an example to illustrate: when the display device 4 is in the Figure 1 When the display device 4 is raised to a preset height as shown, when it is necessary to lower the display device 4, the winding device 1 rotates clockwise, at which time the traction member 11 is released, and the lifting bracket 22 descends relative to the fixed bracket 21, thereby driving the display device 4 to descend and be flush with the performance device; when the display device 4 is in a state as shown Figure 3 In the falling state shown, when the display device 4 needs to be raised, the winding device 1 rotates counterclockwise, and the traction member 11 is retracted. The lifting bracket 22 rises relative to the fixed bracket 21, thereby driving the display device 4 to rise to a preset height. Figure 1The lifting process of the lifting assembly 2 on the right side is opposite to that of the lifting assembly on the left side, that is, the winding device 1 rotates counterclockwise, at which time the traction member 11 is released, and the lifting bracket 22 descends relative to the fixed bracket 21, thereby driving the display device 4 to descend and be flush with the performance device; when the display device 4 is in a position as shown in FIG. Figure 3 In the falling state shown, when the display device 4 needs to be raised, the winding device 1 rotates clockwise, and the traction member 11 is retracted. The lifting bracket 22 rises relative to the fixed bracket 21, thereby driving the display device 4 to rise to a preset height.

[0080] The fixed bracket 21 is further explained below. It can be understood that the present embodiment preferably has two sets of lifting components that are arranged opposite to each other and have the same structure. The following explanation will only take one set of lifting components as an example, and will not be repeated for the two sets of lifting components. Figure 5 The figure is a schematic diagram of the structure of a fixed bracket in a group of lifting components on the left side. Specifically, the fixed bracket 21 includes a fixed bracket body 211; two first sliding wheels 212, which are respectively arranged on opposite sides of the fixed bracket body 211; and two second sliding wheels 213, which are respectively arranged on opposite sides of the fixed bracket body 211; and the first sliding wheel 212 is arranged at one end of the fixed bracket body 211 close to the support surface, that is, the first sliding wheel 212 is located at the bottom end of the fixed bracket body 211, and the second sliding wheel 213 is arranged at one end of the fixed bracket body 211 away from the support surface, that is, the second sliding wheel 213 is arranged above the first sliding wheel 212, more specifically, the second sliding wheel 213 is located at the top of the fixed bracket body 211; the traction member 11 is led out from the winding device 1, and is sequentially wound on the first sliding wheel 212 and the second sliding wheel 213, and then connected to the lifting bracket 22.

[0081] Specifically, the first sliding wheel 212 and the second sliding wheel 213 are equivalent to the fixed pulleys. Figure 1 The lifting assembly 2 on the left is used as an example to illustrate: when the display device 4 is in the Figure 1 When the display device 4 is lowered to a preset height, the winding device 1 rotates clockwise to release the traction member 11. The traction member 11 is wound around the second sliding wheel 213 and the first sliding wheel 212 in sequence and then wound into the winding device 1. Since the free end of the traction member 11 is connected to the lifting bracket 22, the traction member 11 is moved along the winding device 1. Figure 1 When the first wiring track p shown in FIG. 1 moves, the lifting bracket 22 is driven to descend relative to the fixed bracket 21, thereby driving the display device 4 to descend and be flush with the performance device; when the display device 4 is in a position as shown in FIG. Figure 3In the descending state shown in the figure, when the display device 4 needs to be raised, the winding device 1 rotates counterclockwise, and the traction member 11 is retracted at this time. The traction member 11 passes through the first sliding wheel 212 and the second sliding wheel 213 in sequence and is fixed on the lifting bracket 22. Since the free end of the traction member 11 is connected to the lifting bracket 22, the traction member 11 moves along the Figure 1 When the second wiring track m shown in FIG. 1 moves, the winding device 1 pulls the traction member 11 back, so that the traction member 11 drives the lifting bracket 22 to rise relative to the fixed bracket 21, thereby driving the display device 4 to rise to a preset height.

[0082] against Figure 1 The lifting process of the lifting assembly 2 on the right side is opposite to the lifting process of the lifting assembly 2 on the left side, that is, when the display device 4 is in the position as shown in FIG. Figure 1 When the display device 4 is lowered to a preset height, the winding device 1 rotates counterclockwise to release the traction member 11. The traction member 11 is wound around the second sliding wheel 213 and the first sliding wheel 212 in sequence and then wound into the winding device 1. Since the free end of the traction member 11 is connected to the lifting bracket 22, the traction member 11 is moved along the winding device 1. Figure 1 When the first wiring track p shown in FIG. 1 moves, the lifting bracket 22 is driven to descend relative to the fixed bracket 21, thereby driving the display device 4 to descend and be flush with the performance device; when the display device 4 is in a position as shown in FIG. Figure 3 In the descending state shown in the figure, when the display device 4 needs to be raised, the winding device 1 rotates clockwise, and the traction member 11 is retracted at this time. The traction member 11 passes through the first sliding wheel 212 and the second sliding wheel 213 in sequence and is fixed on the lifting bracket 22. Since the free end of the traction member 11 is connected to the lifting bracket 22, the traction member 11 moves along the lifting bracket 22. Figure 1 When the second wiring track m shown in FIG. 1 moves, the winding device 1 pulls the traction member 11 back, so that the traction member 11 drives the lifting bracket 22 to rise relative to the fixed bracket 21, thereby driving the display device 4 to rise to a preset height.

[0083] Optional, such as Fig.10 As shown, the performance device of this embodiment also includes a first controller 5, which is electrically connected to the winding device 1 and is used to control the winding device 1 to retract or release the traction member 11. As can be seen from the above, the retraction or release length of the traction member 11 determines the rising or falling height of the lifting bracket 22. Therefore, in order to accurately control the rising or falling height or distance of the lifting bracket 22, a first controller 5 can be provided to control the speed and length of the winding device 1 to retract or release the traction member 11. Specifically, the first controller 5 can be a control switch or button of the winding device 1 (such as a winch).

[0084] like Figure 1 , Figure 5 , Figure 6 As shown, the lifting bracket 22 includes a first lifting bracket 221, which can be accommodated in the fixed bracket 21 and can be lifted relative to the fixed bracket 21; the first lifting bracket 221 includes: a first lifting bracket body 2211; two third sliding wheels 2212, which are arranged on opposite sides of one end of the first lifting bracket body 2211 close to the support surface (that is, the third sliding wheels 2212 are roughly arranged at the bottom of the first lifting bracket body 2211). The traction member 11 is wound around the fixed bracket 21 and then wound around and fixed on the third sliding wheels 2212, so that when the traction member 11 is subjected to traction, the first lifting bracket 221 is driven to rise relative to the fixed bracket 21; or when the traction member 11 is subjected to counter-traction, the first lifting bracket 221 is caused to fall relative to the fixed bracket 21.

[0085] That is, although the third sliding wheel 2212 is fixed on the first lifting bracket body 2211, it is equivalent to a movable pulley, which is used to realize the lifting movement of the first lifting bracket 221 relative to the fixed bracket 21 under the action of traction. Figure 1 The lifting assembly 2 on the left is used as an example to illustrate: when the display device 4 is in the Figure 1 When the display device 4 is raised to a preset height, the winding device 1 rotates clockwise to release the traction member 11. The traction member 11 is wound around the third sliding wheel 2212, the second sliding wheel 213, and the first sliding wheel 212 in sequence and then wound into the winding device 1. Since the free end of the traction member 11 is wound around the third sliding wheel 2212 and fixed on the first lifting bracket body 2211, the traction member 11 is moved along the winding device 1. Figure 1 When the first wiring track p shown in FIG. 1 moves, the first lifting bracket 221 is driven to descend relative to the fixed bracket 21, thereby driving the display device 4 to descend and be flush with the performance device; when the display device 4 is in a position as shown in FIG. Figure 3 In the descending state shown in the figure, when the display device 4 needs to be raised, the winding device 1 rotates counterclockwise, and the traction member 11 is retracted. The traction member 11 passes through the first sliding wheel 212, the second sliding wheel 213, and the third sliding wheel 2212 in sequence and is fixed to the first lifting bracket body 2211. Figure 1 When the second wiring track m shown in moves, the winding device 1 pulls the traction member 11 back, so that the traction member 11 drives the first lifting bracket 221 to rise relative to the fixed bracket 21, thereby driving the display device 4 to rise to a preset height.

[0086] against Figure 1 The lifting process of the lifting assembly 2 on the right side is opposite to the lifting process of the lifting assembly 2 on the left side, that is, when the display device 4 is in the position as shown in FIG. Figure 1When the display device 4 is raised to a preset height, the winding device 1 rotates counterclockwise to release the traction member 11. The traction member 11 is wound around the third sliding wheel 2212, the second sliding wheel 213, and the first sliding wheel 212 in sequence and then wound into the winding device 1. Since the free end of the traction member 11 is wound around the third sliding wheel 2212 and fixed on the first lifting bracket body 2211, the traction member 11 is moved along the first lifting bracket body 2211. Figure 1 When the first wiring track p shown in FIG. 1 moves, the first lifting bracket 221 is driven to descend relative to the fixed bracket 21, thereby driving the display device 4 to descend and be flush with the performance device; when the display device 4 is in a position as shown in FIG. Figure 3 In the descending state shown in the figure, when the display device 4 needs to be raised, the winding device 1 rotates clockwise, and the traction member 11 is retracted at this time. The traction member 11 passes through the first sliding wheel 212, the second sliding wheel 213, and the third sliding wheel 2212 in sequence and is fixed to the first lifting bracket body 2211. Figure 1 When the second wiring track m shown in moves, the winding device 1 pulls the traction member 11 back, so that the traction member 11 drives the first lifting bracket 221 to rise relative to the fixed bracket 21, thereby driving the display device 4 to rise to a preset height.

[0087] like Figure 5 , Figure 6 As shown, the fixed bracket 21 also includes a fourth sliding wheel 214, which is arranged on the fixed bracket 21 and is flush with the second sliding wheel 213; and the line connecting the center of the fourth sliding wheel 214 and the center of the third sliding wheel 2212 is parallel to the lifting direction of the lifting bracket 22, so that the trajectory of the traction member 11 between the third sliding wheel 2212 and the fourth sliding wheel 214 is parallel to the lifting direction of the lifting component 2, so that the lifting component 2 can rise or fall more smoothly without tilting, that is, the fourth sliding wheel 214 plays a role in converting the trajectory of the traction member 11.

[0088] Further integration Figure 7As shown, the lifting bracket 22 also includes a second lifting bracket 222, which can be accommodated in the first lifting bracket 221 and can be lifted relative to the fixed bracket 21 and the first lifting bracket 221. The second lifting bracket 222 has a second lifting bracket body 2221, on which a first fixing member 2222 is provided, and the first fixing member 2222 is specifically arranged at the bottom of the second lifting bracket body 2221. In order to realize the lifting transmission of the second lifting bracket 222, the lifting bracket 22 of this embodiment is provided with a first group of transmission components, and the first group of transmission components, in addition to the above-mentioned first fixing member 2222, also includes: a second fixing member 215 is provided on the fixed bracket 21, a fifth sliding wheel 2213 is provided on the first lifting bracket 221, and the lifting bracket 22 of this embodiment is also provided with a first transmission chain 224. The fifth sliding wheel 2213 is disposed at one end of the first lifting bracket 221 away from the supporting surface, and is located at the side of the third sliding wheel 2212 away from the supporting surface (i.e., the fifth sliding wheel 2213 is located above the third sliding wheel 2212); one end of the first transmission chain 224 is fixedly connected to the first fixing member 2222, and the other end is fixedly connected to the second fixing member 215 after passing through the fifth sliding wheel 2213. In this way, when the first lifting bracket 221 is lifted or lowered relative to the fixing bracket 21, since the fifth sliding wheel 2213 is lifted or lowered, but the end of the first transmission chain 224 connected to the second fixing member 215 is stationary, the second lifting bracket 222 is driven to be lifted or lowered in conjunction with the lifting or lowering of the first lifting bracket 221.

[0089] That is, the length of the first transmission chain 224 is fixed, one end of which is fixed on the fixed bracket 21, and the other end is fixed on the bottom end of the second lifting bracket 222. When the first lifting bracket 221 rises, the first lifting bracket 221 rises and pushes the second lifting bracket 222 to rise, that is, the length of the first transmission chain 224 between the fifth sliding wheel 2213 and the second lifting bracket body 2221 is reduced, and the distance between the first transmission chain 224 between the fifth sliding wheel 2213 and the fixed bracket 21 is increased; and when the first lifting bracket 221 descends, the first lifting bracket 221 descends and drives the second lifting bracket 222 to descend, that is, the length of the first transmission chain 224 between the fifth sliding wheel 2213 and the second lifting bracket body 2221 is increased, and the distance between the first transmission chain 224 between the fifth sliding wheel 2213 and the fixed bracket 21 is reduced.

[0090] In summary, this embodiment indirectly drives the second lifting bracket 222 to rise or fall at the same time by the rise and fall of the first lifting bracket 221. Compared with the scheme that uses pulleys and traction members to drive the first lifting bracket and the second lifting bracket to rise and fall, which causes the traction member to be too long and easy to break, resulting in unstable lifting, this embodiment only uses the traction member 11 when the first lifting bracket 221 rises or falls. The traction member 11 only needs to pull the first lifting bracket 221 to rise or fall, so its length is shorter. At the same time, when the first lifting bracket 221 rises or falls, it indirectly drives the second lifting bracket 222 to rise or fall at the same time, so the whole lifting process is more stable.

[0091] Further integration Figure 8 As shown, the lifting bracket 22 also includes a third lifting bracket 223, which can be accommodated in the second lifting bracket 222 and can be lifted relative to the fixed bracket 21 and the second lifting bracket 222. The third lifting bracket 223 has a third lifting bracket body 2231, on which a third fixing member 2232 is provided, and the third fixing member is specifically arranged at the bottom of the third lifting bracket body 2231. In order to realize the lifting transmission of the third lifting bracket 223, the lifting bracket 22 of this embodiment is provided with a second group of transmission components, which, in addition to deleting the third fixing member 2232, also includes: a fourth fixing member 2214 is provided on the first lifting bracket 221, a sixth sliding wheel 2223 is provided on the second lifting bracket 222, and the lifting bracket 22 of this embodiment is also provided with a second transmission chain 225. Among them, the sixth sliding wheel 2223 is arranged at one end of the second lifting bracket 222 away from the supporting surface, specifically at the top of the second lifting bracket body 2221; one end of the second transmission chain 225 is fixedly connected to the third fixing member 2232, and the other end is fixedly connected to the fourth fixing member 2214 after passing through the sixth sliding wheel 2223. In this way, when the second lifting bracket 222 is linked with the first lifting bracket 221 and then lifted and lowered, the sixth sliding wheel 2223 will be lifted and lowered, thereby driving the length of the second transmission chain 225 located on both sides of the sixth sliding wheel 2223 to change, and finally the third lifting bracket 223 is lifted and lowered in linkage with the lifting and lowering of the second lifting bracket 222.

[0092] That is, the length of the second transmission chain 225 is fixed, one end of which is fixed to the first lifting bracket 221, and the other end is fixed to the bottom end of the third lifting bracket 223. When the first lifting bracket 221 or the second lifting bracket 222 rises, the first lifting bracket 221 and the second lifting bracket 222 rise and push the third lifting bracket 223 to rise; and when the first lifting bracket 221 or the second lifting bracket 222 falls, the first lifting bracket 221 and the second lifting bracket 222 fall and drive the third lifting bracket 223 to rise.

[0093] In order to explain the above complex lifting process more clearly, please combine Fig. 9 As shown, Fig. 9 This is a diagram illustrating the principle of lifting of three lifting brackets. It should be noted that in order to more clearly explain the linkage between the lifting brackets during the lifting process, Fig. 9 In the figure, some structures of each lifting bracket, such as sliding wheels, fixing parts, transmission chains and other structures and their positions are only schematically marked, for example: Fig. 9 In order to clearly illustrate the linkage of the second lifting bracket with respect to the first lifting bracket, only the fifth sliding wheel in the first lifting bracket, the first fixing member of the second lifting bracket and the second fixing member of the fixing bracket and their positions are schematically shown, which does not mean that Fig. 9 The positions shown in are specific limitations of the actual solution.

[0094] like Fig. 9 As shown, the lifting process of the first lifting bracket 221 is: through the action of the traction member on the first sliding wheel and the second sliding wheel (preferably, the fourth sliding wheel), the third sliding wheel 2212 on the first lifting bracket 221 is driven to lift and lower, thereby driving the entire first lifting bracket 221 to lift and lower relative to the fixed bracket 21.

[0095] The lifting process of the second lifting bracket 222 is as follows: when the first lifting bracket 221 is lifted and lowered relative to the fixed bracket 21, the fifth sliding wheel 2213 of the first lifting bracket 221 will also be lifted and lowered. At this time, the lengths of the two sections of the first transmission chain 224 located on both sides of the fifth sliding wheel 2213 and connected to the first fixing member 2222 of the second lifting bracket 222 and the second fixing member 215 of the fixed bracket 21 respectively will change, thereby causing the second lifting bracket 222 to also be lifted and lowered.

[0096] The lifting process of the third lifting bracket 223 is similar to that of the second lifting bracket 222: when the second lifting bracket 222 is lifted and lowered relative to the first lifting bracket 221, the sixth sliding wheel 2223 of the second lifting bracket 222 will also be lifted and lowered. At this time, the lengths of the two sections of the second transmission chain 225 located on both sides of the sixth sliding wheel 2223 and connected to the third fixing member 2232 of the third lifting bracket 223 and the fourth fixing member 2214 of the first lifting bracket 221 respectively will change, thereby causing the third lifting bracket 223 to also be lifted and lowered.

[0097] In summary, this embodiment indirectly drives the third lifting bracket 223 to rise or fall at the same time by the rise and fall of the first lifting bracket 221 or the second lifting bracket 222. Compared with the scheme in the related art that uses pulleys and traction members to drive the first lifting bracket, the second lifting bracket and the third lifting bracket to rise and fall, which causes the traction member to be too long and easy to break, resulting in unstable lifting, this embodiment only uses the traction member 11 when the first lifting bracket 221 rises or falls. The traction member 11 only needs to pull the first lifting bracket 221 to rise or fall, so its length is shorter. At the same time, when the first lifting bracket 221 rises or falls, it indirectly drives the second lifting bracket 222 to rise or fall at the same time, and drives the third lifting bracket 223 to rise or fall at the same time, so the whole lifting process is more stable.

[0098] The traction member of this embodiment is only used to traction the first lifting bracket to rise and fall, and the second lifting bracket and the third lifting bracket are lifted and lowered by the first transmission chain and the second lifting chain respectively. Therefore, the lifting and lowering of the first lifting bracket, the second lifting bracket and the third lifting bracket are realized by the combination of the traction member and the first transmission chain and the second transmission chain, so that the traction member, the first transmission chain and the second transmission chain are relatively independent, so that it is easy to replace or repair when any one of them breaks. In addition, compared with traction members such as wire ropes, the first transmission chain and the second transmission chain have better wear resistance and therefore have a longer service life.

[0099] like Figure 1 As shown, according to the above, the lifting assembly 2 includes two left and right arrangements, and in order to simultaneously drive the lifting and lowering of the two lifting assemblies 2 on the left and right, the winding device 1 of this embodiment includes two, and the two winding devices 1 respectively retract and release the corresponding traction members 11 to control the lifting and lowering of the corresponding lifting assembly 2. And in order to ensure the same frequency or synchronous rise or fall of the lifting assembly 2, and ensure the smoothness of the rise or fall of the display device 4 to prevent tilting, in this embodiment, the performance device also includes a synchronization device 7, and the synchronization device 7 is respectively connected to the two winding devices 1, and is used to enable the two winding devices 1 to control the corresponding lifting assembly 2 to rise and fall synchronously. The synchronization device 7 can be selected from the synchronizer in the relevant technology, and this embodiment does not make a specific limitation.

[0100] like Figure 1 , Figure 4 , Fig.10 As shown, the performance device also includes a control component 41 and a light-emitting component 42 which are communicatively connected to each other. The light-emitting component 42 is arranged on the outer wall of the display device 4 and is electrically connected to an external power supply through a cable. The control component 41 is used to control the light-emitting component 42 to emit illumination light to cooperate with the performance effect of the performance device, thereby providing users with a richer viewing experience.

[0101] In one implementation, each light-emitting component 42 can be electrically connected to the same control component 41, and the control component 41 is used to control each light-emitting component 42 to emit illumination light, that is, all the light-emitting components 42 can be turned on or off by one control component 41, so that the control of the light-emitting components 42 is more convenient.

[0102] In another implementation, in order to facilitate the individual control of the opening and closing of each light-emitting component 42 to coordinate with the performance effect of the performance device, each light-emitting component 42 can also be electrically connected to the corresponding control component 41, and each control component 41 is used to control the corresponding light-emitting component 42 to emit irradiation light, so that the control of the light-emitting components 42 is independent of each other, so as to flexibly control the opening and closing of the required light-emitting components 42 according to the performance effect. For example, each light-emitting component 42 has a control component 41, and each control component 41 is used to control the opening or closing of the light-emitting component 42 electrically connected to it. In addition, a general control unit can be provided to control the working state of the control component 41 electrically connected to all the light-emitting components 42, so that all the light-emitting components 42 can be conveniently controlled to be turned on or off when it is necessary to control all the light-emitting components 42 to be turned on or off.

[0103] It should be noted that, in the present embodiment, the electrical connection between the light-emitting component 42 and the control component 41 is specifically achieved through a cable, and the light-emitting component 42 can be a common LED light strip or LED light tube in the relevant technology, or a common spotlight, etc.; the control component 41 is a common switch in the relevant technology or a controller with an opening and closing function, which is selected according to actual needs, and this embodiment does not provide a specific model example for this.

[0104] In this embodiment, the light-emitting component 42 can be a plurality of independent spotlights, each of which is evenly spaced and distributed on the outer wall of the display device 4. Each of the spotlights can be electrically connected to the same control component 41, and the control component 41 is used to control each of the spotlights to emit irradiation light, that is, all the spotlights can be turned on or off through one control component 41, so that the control of the spotlights is more convenient. It is also possible to set each spotlight to be electrically connected to a corresponding control component 41, and each control component 41 is used to control the corresponding spotlight to emit irradiation light, so that the control of the spotlights is independent of each other, so as to flexibly control the opening and closing of the required spotlights according to the effect of the performance device. For example, each spotlight has a control component 41, and each control component 41 is used to control the corresponding electrically connected spotlight to turn on or off.

[0105] In this embodiment, for the fixing method of the light emitting component 42 on the peripheral wall of the display device 4, the light emitting component 42 may have a connection portion, and the connection portion has a threaded hole or a mounting hole, and the light emitting component 42 may be fixed on the peripheral wall of the display device 4 by passing a fastener (such as a screw or an expansion screw, etc.) through the threaded hole or the mounting hole and fixing it on the side wall of the display device 4. Alternatively, another fixing method is that a buckle or a clamping portion is provided on the peripheral wall of the display device 4, and the light emitting component 42 is fixed on the peripheral wall of the display device 4 by the buckle or inserted in the clamping portion so that the light emitting component 42 is fixed on the peripheral wall of the display device 4. The clamping portion here may be a card slot, etc., and the shape of the card slot matches the outer contour of the light emitting component 42, so that the light emitting component 42 is directly clamped in the clamping portion to realize its connection to the peripheral wall of the display device 4. The fixing method of the light emitting component 42 on the peripheral wall of the display device 4 can refer to the above three examples of this embodiment, and other fixing methods can also be selected according to actual needs, which is not specifically limited in this embodiment.

[0106] In order to make the illumination light emitted by the spotlights enrich the performance effect of the display device 4, in one embodiment, each spotlight is used to emit illumination light of the same color, that is, all spotlights can emit red illumination light, or blue illumination light or yellow illumination light when turned on. The color of the illumination light emitted by the specific spotlight is set according to actual needs, and this embodiment does not make any specific limitation on this.

[0107] In order to make the illumination light emitted by the spotlights enrich the performance effect of the performance device, in another embodiment, some of the spotlights emit illumination light of different colors or wavelength ranges and the colors or wavelength ranges of the illumination light emitted by adjacent spotlights are different, that is, some of the spotlights emit red illumination light, some of the spotlights emit blue illumination light, some of the spotlights emit green illumination light, and some of the spotlights emit yellow illumination light, so that all the spotlights can emit colorful illumination light when turned on, which can further enrich the lighting effect of the performance device. The color and type of the illumination light emitted by the specific spotlights are set according to actual needs, and this embodiment does not specifically limit this. It needs to be explained that in order to make the illumination light emitted by all the spotlights present a colorful lighting effect, the color or wavelength range of the illumination light emitted by adjacent spotlights can be set to be different. For example, if the illumination light emitted by one of the spotlights is red, its two adjacent spotlights can emit blue and yellow illumination light respectively, so that the colors of the illumination light emitted by the adjacent spotlights are different so that the spotlights emitting illumination light of different colors are distributed at intervals.

[0108] like Figure 1 , Figure 4 , Fig.10As shown, the performance device also includes a control component 41 and a water mist component 43 which are communicatively connected to each other, and the water mist component 43 includes: a water storage part, which is arranged in the display device 4 for storing water; a spraying part, which is arranged on the outer peripheral wall of the display device 4 and is connected to the water storage part pipeline; and a boosting part, which is arranged in the pipeline and is electrically connected to the control component 41; wherein: a through hole is provided on the peripheral wall of the display device 4, one end of the pipeline is connected to the water storage part and is connected to the spraying part through the through hole, and the control component 41 controls the boosting component to spray the water source in the water storage part from the spraying part under pressure to present a fountain-like effect, thereby cooperating with the performance effect of the performance device, thereby providing the audience with a richer viewing experience.

[0109] In one implementation, each water mist component 43 can be electrically connected to the same control component 41, and the control component 41 is used to control each water mist component 43 to spray water, that is, all water mist components 43 can be opened or closed by one control component 41, so that the control of the water mist component 43 is more convenient. It should be explained that the control component here is different from the control component for controlling the light-emitting component 42 described above, but can be of the same model or specification as the control component for controlling the light-emitting component 42, that is, the control components for controlling the light-emitting component 42 and the water mist component 43 are different control components, so that the control of the water mist component 43 and the light-emitting component 42 are independent of each other and do not interfere with each other. Alternatively, the control component here can also be the control component for controlling the light-emitting component 42 described above, that is, the control component is used to simultaneously control the opening or closing of the light-emitting component 42 and the water mist component 43, so that the operation is more convenient.

[0110] In another implementation, in order to facilitate the individual control of the opening and closing of each water mist component 43 to coordinate with the performance effect of the performance device, each water mist component 43 can also be electrically connected to the corresponding control component 41, and each control component 41 is used to control the corresponding water mist component 43 to spray water, so that the control of the water mist component 43 is independent of each other, so as to flexibly control the opening and closing of the required water mist component 43 according to the performance effect. For example, each water mist component 43 has a control component 41, and each control component 41 is used to control the opening or closing of the corresponding electrically connected water mist component 43. In addition, a general control unit can be set to control the working state of the control component 41 correspondingly electrically connected to all water mist components 43, so that all water mist components 43 can be conveniently controlled to be opened or closed when all water mist components 43 need to be controlled to be opened or closed.

[0111] It should be noted that, in the present embodiment, the electrical connection between the water mist component 43 and the control component 41 is specifically achieved through a cable, and the water mist component 43 can be a nozzle or a sprayer commonly used in the relevant technology; the control component 41 is a switch commonly used in the relevant technology or a controller with an opening and closing function, which is selected according to actual needs, and this embodiment does not provide a specific model example for this.

[0112] In this embodiment, the water mist component 43 can be fixed on the outer peripheral wall of the display device 4 by having a connection portion with a threaded hole or a mounting hole, and by passing a fastener (such as a screw or an expansion screw, etc.) through the threaded hole or the mounting hole and fixing it on the side wall of the display device 4, thereby fixing the water mist component 43 on the outer peripheral wall of the display device 4. Alternatively, another fixing method is that a buckle is provided on the outer peripheral wall of the display device 4, and the water mist component 43 is fixed on the outer peripheral wall of the display device 4 by the buckle. The fixing method of the water mist component 43 on the outer peripheral wall of the display device 4 can refer to the above two examples of this embodiment, and other fixing methods can also be selected according to actual needs, and this embodiment does not specifically limit this.

[0113] The water mist component 43 includes: a water storage part, a spraying part and a pressurizing part; wherein the water storage part is connected to the spraying part pipeline, so that the pressurizing part located in the pipeline sprays the water source in the water storage part through the spraying part when external pressure is increased or negative pressure is applied to form a fog forest effect to cooperate with the overall effect of the performance device, so that the function of the display device 4 is richer to further enrich the audience's viewing experience.

[0114] In this embodiment, the water storage part is provided in the cavity of the display device 4 for storing water, and the water source is used to be sprayed out later to cooperate with the performance device effect. Specifically, the water storage part can be a water bag or a water tank provided in the cavity of the display device 4. The specific water storage capacity of the water storage part is set according to actual needs, and this embodiment does not specifically limit this.

[0115] In addition, the spraying part is arranged on the outer peripheral wall of the display device 4 and is connected with the water storage part pipeline so that when the external pressure is increased or negative, the water source in the water storage part is pumped to the spraying part and sprayed out through the spraying part to form a fog forest effect. The specific pipeline connection between the water storage part and the spraying part can be connected through a plastic water pipe, a metal pipe or a corrugated pipe commonly used in the relevant technology.

[0116] The booster component is arranged in the pipeline and is electrically connected to the control component 41. The control component 41 controls the booster component to spray the water source in the water storage part from the spraying part under pressure. The booster component can be a common booster pump or water pump, etc., which can be selected according to actual needs, and this embodiment does not make specific limitations on this.

[0117] like Figure 4As shown, the performance device includes a base 3 and a performance device body 8 arranged on one side of the base 3. A through hole 81 with a radius of the diameter of the display device 4 is formed at the center of the performance device body 8. The display device 4 can be located in the through hole 81 after falling.

[0118] like Figure 4 As shown, the outer periphery of the performance device body 8 is provided with a plurality of petal blades 82 at intervals along the circumference of the performance device body 8, and each petal blade 82 is evenly spaced along the circumference of the performance device body 8. The specific setting position and setting number of the petal blades 82 are set according to actual needs, and this embodiment does not specifically limit this. In addition, the petal blades 82 are in the shape of a lotus, so that the entire performance device is in the shape of a lotus, so that it has a smoother outer contour and can enhance the viewing comfort of the audience. And each petal blade 82 has a standing surface s on the side away from the base 3 for the actor to stand, and the performer can also stand on the petal blade 82 to perform, so as to meet the performer's performance needs of the performance device. In addition, in this embodiment, the petal blades 82 are stamped from sheet metal materials.
