The traditional display rack has single function, only simply displays the cultural relics, most of audiences cannot know the knowledge which the audiences want to know by watching the cultural relics, and interactivity is not good. In the intelligent interactive LED display stand 10 of the present invention, a man-machine interaction system 300 (as shown in fig. 1) is additionally arranged on the top of the glass protection cover 200, and better interaction with the audience can be performed by arranging the man-machine interaction system 300. On the one hand, the man-machine interaction system 300 can display the related information of the current cultural relics in the form of pictures or words, on the other hand, the spectator can operate the man-machine interaction system 300 according to the requirements of the spectator, and the content interested by the spectator can be obtained, so that the interactivity is good.

As shown in fig. 3, in particular, in the present invention, the human-computer interaction system 300 includes an angle adjusting device 310 and a touch display 320 mounted on the angle adjusting device 310. By setting the angle adjusting device 310, the angle of the touch display 320 can be adjusted, so that people with different ages and heights can better see the content on the screen.

In order to enable the cultural relics to rotate and enable surrounding viewers to see the overall shape of the cultural relics, the conventional display stand is simply provided with a rotation driving device, and the rotation driving device drives the cultural relics to rotate at a fixed rotation speed. For special persons such as expert scholars, the special requirements for viewing the cultural relics are met, the cultural relics are not required to rotate at a fixed rotating speed, and the autonomous rotation adjustment of the cultural relics is required to be carried out according to the actual requirements.

To this end, the intelligent interactive LED display stand 10 of the present invention is further modified as follows:

the intelligent interactive LED display stand 10 further includes an automated manual drive system 400 (shown in fig. 4) mounted on the base 100 for driving the rotation of the rotary platform 110. The automated manual drive system 400 may be understood as either a general public or a special person depending on the community for which the current relics are directed. If the display is common, the sponsor can choose to automatically rotate the cultural relics in the display rack at a fixed rotating speed; if the display is special, the sponsor can choose to make the cultural relics in the display stand rotate in a manual self-adaptive manner.

As shown in fig. 5, in particular, the manual-automatic driving system 400 includes an integrated frame 410, and a rotation shaft 420, an automatic driving device 430, and a manual driving device 440 mounted on the integrated frame 410.

The rotation shaft 420 is connected to the rotation stage 110.

The automatic driving device 430 is unidirectionally driving-connected with the rotation shaft 420. If the display is common, the sponsor can choose to automatically rotate the cultural relics in the display rack at a fixed rotating speed.

As shown in fig. 5, manual drive 440 is drivingly connected to rotary shaft 420 through overspeed protection device 450. If the display is special, the sponsor can choose to make the cultural relics in the display stand rotate in a manual self-adaptive manner.

When the manual driving device 440 is provided, since the cultural relics are adaptively rotated manually, the rotational speed is not controllable, if the rotational speed is too high, the sudden start speed of the rotary platform 110 is too high, so that a large inertia is generated, and the cultural relics are easy to topple over to cause damage. In addition, for important cultural relics, the rotary platform 110 is not suitable to be provided with related clamping jigs to clamp the cultural relics, which is easy to cause irreversible damage to the cultural relics, so that the cultural relics are preferably placed on the rotary platform 110 directly without blocking.

For this purpose, an overspeed protection device 450 is added between the manual driving device 440 and the rotation shaft 420 to prevent the rotation shaft 420 from suddenly starting at an excessively high speed.

As shown in fig. 5, 6 and 7, specifically, the overspeed protection apparatus 450 includes: a driving disk 451, a driven disk 452, and a torsion spring 453. The driven plate 452 is rotatably arranged on the integrated frame 410, and the driving plate 451 and the driven plate 452 are coaxially and mutually rotatably connected. The driven plate 452 is provided with a notch 454, the driving plate 451 is provided with a bump 455 positioned in the notch 454, the bump 455 is provided with a telescopic spring 456, and one end of the telescopic spring 456 is propped against the wall surface of the notch 454.

The integrated frame 410 is provided with a friction disc 457, an accommodating space 458 is formed between the driven disc 452 and the friction disc 451, a torsion spring 453 is accommodated in the accommodating space 458 (shown in fig. 8), and an outer ring of the torsion spring 453 is in sliding contact with the inner wall of the friction disc 457; wherein the end of torsion spring 453 is located between tab 455 and the wall of notch 454.

As shown in fig. 5, the manual driving device 440 includes a dial 441 and a dial gear 442 disposed on the dial 441, and the dial gear 442 is engaged with the driving plate 451.

Next, the operation principle of the overspeed protection apparatus 450 will be described:

as shown in fig. 9, the dial wheel 441 is rotated by a human hand, and the dial wheel 441 further drives the driving disc 451 to rotate through the dial gear 442;

as shown in fig. 9, if a hand is slowly pulling the pulling wheel disc 441, the driving disc 451 is slowly started, the protrusion 455 on the driving disc 451 pushes the wall surface of the notch 454 through the telescopic spring 456, the driven disc 452 is pushed by the telescopic spring 456 to rotate, and it is understood that in the early stage, the wall surface of the notch 454 of the driven disc 452 contacts with the end of the torsion spring 453 in the process of rotating together, so that the whole torsion spring 453 is contracted towards the center, the friction force between the outer ring of the torsion spring 453 and the inner wall of the friction disc 457 is reduced (the torsion spring 453 is not limited by the friction disc 457), and in the later stage, the driving disc 451, the driven disc 452 and the torsion spring 453 can rotate together, so that the driving disc 451 drives the rotating shaft 420 engaged with the driving disc 451 to rotate, and the rotating platform 110 is driven by the rotating shaft 420 to rotate;

as shown in fig. 9, if a hand is pulling the pulling wheel disc 441 quickly, the driving disc 451 is started quickly, at the instant of this quick start, the telescopic spring 456 is compressed suddenly (the driven disc 452 is not rotated yet), and since the driving disc 451 rotates earlier than the driven disc 452, the bump 455 on the driving disc 451 contacts with the end of the torsion spring 453, so that the whole torsion spring 453 expands outwards, the friction between the outer ring of the torsion spring 453 and the inner wall of the friction disc 457 becomes large (the torsion spring 453 is tightly bound by the friction disc 457), the driving disc 451 cannot rotate any more, the rotating shaft 420 engaged with the driving disc 451 cannot rotate, and the rotating platform 110 cannot rotate, thereby achieving the purpose of overspeed protection.

Here, it is also specifically noted that the manual-automatic driving system 400 of the present invention may implement manual adjustment (via the manual driving device 440) and may implement automatic adjustment (via the automatic driving device 430), and the automatic driving device 430 and the manual driving device 440 are integrated on the integrated frame 410, so that interference between the manual driving device 440 and the automatic driving device 430 cannot occur during manual adjustment or during automatic adjustment, and it is necessary to ensure smoothness of respective operations.

For this purpose, the automatic driving device 430 of the present invention is in unidirectional driving connection with the rotation shaft 420. Specifically, the rotary shaft 420 is provided with an outer ring gear 421 and an inner ring gear 422 (as shown in fig. 5 and 8). The driving disk 451 has a gear structure, and the outer gear ring 421 of the rotation shaft 420 is engaged with the driving disk 451; as shown in fig. 8, the output end of the automatic driving device 430 is provided with a pawl 431, one end of the pawl 431 is rotatably provided at the output end of the automatic driving device 430 by a torsion spring (not shown), and the other end of the pawl 431 abuts against the inner gear ring 422 of the rotating shaft 420.

As shown in fig. 10, when the manual-automatic driving system 400 starts automatic adjustment, the output end of the automatic driving device 430 drives the pawl 431 to rotate clockwise, the pawl 431 drives the rotating shaft 420 to rotate through the annular gear 422, and the rotating shaft 420 drives the rotating platform 110 to rotate; during the rotation of the rotation shaft 420, the external gear ring 421 also drives the driving disc 451 to rotate, and the driving disc 451 further drives the dial wheel 441 of the manual driving device 440 to rotate, but this does not prevent the automatic adjustment function of the manual driving system 400; also, since the rotational speed of the automatic drive 430 is very slow, the overspeed protection apparatus 450 does not initiate overspeed protection;

as shown in fig. 9, when the manual adjustment is started by the manual-automatic driving system 400, the dial wheel 441 is dialed clockwise, so that the driving disc 451 rotates counterclockwise, and the driving disc 451 drives the rotation shaft 420 to rotate clockwise, so that the pawl 431 in the current state does not obstruct the rotation shaft 420 rotating clockwise, and the manual adjustment function of the manual-automatic driving system 400 is smoothly performed; it is also possible to obtain that the dial wheel 441 is dialed in a clockwise direction, and the rotary platform 110 finally rotates in a clockwise direction, which accords with the normal hand-eye adjustment habit of people.

In this embodiment, the automatic driving device 430 includes a motor and a gear reducer used in cooperation with the motor, and the pawl 431 is disposed on a gear output shaft of the gear reducer.

According to the intelligent interaction LED display stand 10, on the basis that man-machine interaction can be achieved, automatic rotation adjustment can be conducted on a display product according to the requirements of special persons.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
