[0038] like Figures 1 to 8 As shown, the automatic flush double-door device for performing arts in this embodiment includes a front support mechanism 1 and a rear support mechanism 2 arranged front and back, the front support mechanism 1 is provided with two front display screen systems 3 arranged in the same plane, and a passage portion 4 for people to pass through is formed between the two front display screen systems 3, and two rear display screen systems 5 arranged in the same plane are provided on the rear support mechanism 2 at the corresponding passage portion 4, and the passage portion 4 is closed when used in the performing state so that the two front display screen systems 3 and the two rear display screen systems 5 form a flat display plane, and each rear display screen system 5 includes a front and rear driving mechanism 51 and a left and right driving mechanism 52, and when used in the passing state, the two rear display screen systems 5 are first synchronously withdrawn to the rear and then translated to the left and right to open the passage portion 4. The specific implementation principle is as follows:

[0039] In the performance state, the two rear display screen systems 5 arranged in the same plane are combined, and the channel part 4 is closed, so that the two rear display screen systems 5 are arranged between the two front display screen systems 3, that is, the two front display screen systems 3 and the two rear display screen systems 5 form a flat display plane, so that the display area is large and the display effect is good. Figure 1 shown.

[0040] When a traffic state is required, such as the sudden entry of actors or guests, the two rear display screen systems 5 are driven by the front and rear drive mechanisms 51 to synchronously withdraw backwards, so that the two rear display screen systems 5 and the two front display screen systems 3 are no longer in the same plane. Figure 4 Then, driven by the left and right driving mechanisms 52, the two rear display screen systems 5 are respectively translated to the left and right, and are respectively translated to the rear of the front display screen system 3. At this time, the passage 4 between the two front display screen systems 3 is opened, as shown in FIG. Figure 2 As shown, it is convenient for the sudden entry of actors and guests.

[0041] After entering, the two rear display screen systems 5 are respectively translated to the left and right to be merged and brought together under the drive of the left and right driving mechanisms 52, and then the two brought together rear display screen systems 5 are synchronously moved forward together under the drive of the front and rear driving mechanisms 51, so that the two rear display screen systems 5 and the two front display screen systems 3 are restored to the same plane again, so that the display area is large and the display effect is good.

[0042] Through the above special scientific design, it has the following technical advantages:

[0043] First, the automatic flush double-door device for performing arts of the present invention is provided with a front support mechanism 1, a rear support mechanism 2, a front display screen system 3, and a rear display screen system 5 that cooperate with each other. In the performing arts state, the passage part 4 can be closed, so that the two front display screen systems 3 and the two rear display screen systems 5 form a flat display plane with a large display area and good display effect. When the sudden entry of actors and guests is required, the passage part 4 can be formed to facilitate the rapid entry of actors and guests, so that it can be opened and closed to provide different viewing experiences and good performing arts effects.

[0044] Secondly, the automatic flush double-door device for performances of the present invention has a modular frame structure, and its structural parts are all processed after welding, and all matching surfaces are machined, which greatly improves the assembly accuracy. The display screen system is quick to install and build, will not affect the progress of the performance, and has low construction cost and high construction efficiency.

[0045] In this embodiment, each rear display screen system 5 includes a main frame 53 and a first display screen frame 54, and a plurality of display screens 6 are mounted on the first display screen frame 54. The first display screen frame 54 is slidably mounted on the main frame 53 through a first slide rail assembly 55, so as to slide forward and backward toward the main frame 53 under the drive of the front and rear drive mechanism 51. In this embodiment, the first slide rail assembly 55 includes a plurality of slide rails fixed on the main frame 53, and the sliders on the slide rails are fixedly connected to the first display screen frame 54.

[0046] In the present embodiment, the front and rear drive mechanism 51 comprises a first motor 511 fixed on the main frame 53 and two optical axis ball screw slides 512 arranged up and down, the slide portion of the optical axis ball screw slide 512 is connected to the first display screen frame 54, the first motor 511 is arranged between the two optical axis ball screw slides 512, and is simultaneously connected to the two optical axis ball screw slides 512 by the first synchronous belt assembly 513. In the present embodiment, the first motor 511 is a servo motor. Through the transmission cooperation of the servo motor, the first synchronous belt assembly 513, and the two optical axis ball screw slides 512, the drive synchronization accuracy is high and the installation space is small. Of course, in other embodiments, other drive mechanisms, such as screw mechanisms, gear rack mechanisms, etc., can also be used, which should all belong to the protection scope of the present invention.

[0047] In this embodiment, the main frame 53 is slidably mounted on the rear support mechanism 2, and the left and right driving mechanism 52 includes a second motor 522 and a screw rod 521 fixed on the rear support mechanism 2 along the left and right translation direction, and the nut seat 523 on the screw rod 521 is fixedly connected to the first display screen frame 54. The second motor 522 is connected to the screw rod 521 through the second synchronous belt assembly 524, so as to drive the main frame 53 to drive the first display screen frame 54 to move back and forth. The second motor 522 drives the screw rod 521 to rotate through the second synchronous belt assembly 524, so that the screw rod nut in the nut seat 523 rotates, and then drives the first display screen frame 54 to move horizontally through the nut seat 523. In this embodiment, the second motor 522 is a servo motor, so that the driving synchronization accuracy is high. At the same time, this special driving matching method greatly saves the installation space and also increases the door opening distance.

[0048] In this embodiment, the top of each main frame 53 is slidably mounted on the rear support mechanism 2 through the second slide rail assembly 56, and the bottom of each main frame 53 is slidably mounted on the working ground through the third slide rail assembly 57. The upper and lower limit sliding mode allows the main frame 53 to move back and forth with high precision without shaking.

[0049] In this embodiment, each front display screen system 3 includes a second display screen frame 31 and a translation drive electric cylinder 32. A plurality of display screens 6 are mounted on the second display screen frame 31. The second display screen frame 31 can be slid left and right on the front support mechanism 1 through the fourth slide rail assembly 58. The translation drive electric cylinder 32 is fixed on the front support mechanism 1 and is used to drive the second display screen frame 31 to translate outward before the rear display screen system 5 moves backward. In order to make the two front display screen systems 3 and the two rear display screen systems 5 form a flatter display plane and improve the performance effect, it is necessary to make the two front display screen systems 3 and the two rear display screen systems 5 contact closely and reduce the gap. However, such a setting may cause risks or poor movement when the rear display screen system 5 moves backward. For this reason, the present invention further makes improvements and sets the two second display screen frames 31 to be able to translate outward. This means that before the rear display screen system 5 moves backward, the translation drive electric cylinder 32 will be controlled to work, so as to push the two second display screen frames 31 to move outward for a distance, so as to facilitate the movement of the rear display screen system 5. When the two rear display screen systems 5 that have come together move forward synchronously, the translation drive electric cylinder 32 will simultaneously drive the two front display screen systems 3 to move together, and finally the two rear display screen systems 5 and the two front display screen systems 3 will be restored to the same plane again, so that the display area is large and the display effect is good. That is, the problems of flatness of the approach, safety and stability of movement, and convenience of movement are well taken into consideration.

[0050] In this embodiment, a top display screen system 7 is further provided on the front support mechanism 1 above the channel portion 4 and the two front display screen systems 3. The top display screen system 7 and the two front display screen systems 3 are arranged in the same plane. The top display screen system 7 includes a third display screen frame 71 and a lifting drive electric cylinder 72. A plurality of display screens 6 are mounted on the third display screen frame 71. The third display screen frame 71 can be slidably mounted on the front support mechanism 1 through the fifth slide rail assembly 59. The lifting drive electric cylinder 72 is fixed on the front support mechanism 1 and is used to drive the third display screen frame 71 to translate upward before the rear display screen system 5 performs a backward exit action. By arranging the top display screen system 7 on the top, the display area of ​​the combined display screen is further increased, and the display effect is good. Of course, as mentioned above, by setting the lifting drive electric cylinder 72 to drive the third display screen frame 71 to move upward, before the rear display screen system 5 moves backward, the translation drive electric cylinder 32 will be controlled to operate to push the two second display screen frames 31 to move a certain distance toward the outside respectively, and at the same time, the lifting drive electric cylinder 72 will be controlled to drive the third display screen frame 71 to move upward for a certain distance, so as to facilitate the movement of the rear display screen system 5.

[0051] When the two rear display screen systems 5 that have come together move forward synchronously, the translation drive electric cylinder 32 will drive the two front display screen systems 3 to move together, and the lifting drive electric cylinder 72 will also drive the third display screen frame 71 to move downward and together, so that the two rear display screen systems 5, the two front display screen systems 3, and the top display screen system 7 are finally restored to the same plane, so that the display area is large and the display effect is good. That is, the problems of smoothness of the approach, safe and stable movement, and convenience of movement are well taken into consideration.

[0052] In this embodiment, a plurality of positioning components are also included, and the plurality of positioning components are respectively fixed on the front support mechanism 1 and the rear support mechanism 2 for performing mobile real-time positioning.
