[0003] In a conference scenario, since the conference hall is large, participants may not be able to see the content on the podium demonstration screen clearly due to angle or distance. Therefore, it is necessary to set up an independent interactive machine for each participant to realize the intelligent display of the content of the podium demonstration screen. The interactive machines in the prior art are mostly electronic screens. However, the electronic screens are large in size, which will block the vision of the participants to a certain extent and occupy a large space on the desktop, causing inconvenience to the participants when not in use. At the same time, the existing interactive machines based on electronic screens can only achieve one-way information transmission, that is, the content can only be transmitted from the podium demonstration screen or the podium host to the interactive machine, which makes it impossible for participants to provide feedback through the interactive machine, causing difficulties in conference communication.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] The present invention provides a conference intelligent interactive machine 10, such as Figure 1 and Figure 2 As shown, it comprises: a base 100 , a projection device 200 and a display device 300 , wherein the projection device 200 is disposed on the base 100 .

[0032] Among them, Figure 2 and Figure 3 As shown, the display device 300 includes: a rotating shaft 310, a display screen 320, a support beam 330 and two telescopic rods 340. The base 100 is provided with a receiving cavity 110, the rotating shaft 310 is arranged in the receiving cavity 110 through a torsion spring (not shown), the display screen 320 is curled and wound around the rotating shaft 310, the free end of the display screen 320 is connected to the support beam 330, and the two telescopic rods 340 are respectively located at the two ends of the rotating shaft 310, and the two ends of each telescopic rod 340 are respectively connected to the support beam 330 and the base 100.

[0033] The telescopic rod 340 is a hollow structure. Figure 2 and Figure 3 As shown, two one-way valves 120 are provided on the base 100, and the two one-way valves 120 correspond to the two telescopic rods 340 respectively. The base 100 is provided with a gas transmission channel 101 (such as Figure 6 As shown), the one-way valve 120 is connected to the telescopic rod 340 through the air supply channel 101.

[0034] In this embodiment, if Figure 3 and Figure 4 As shown, the projection device 200 includes a fixed bracket 210 and a projector 220 rotatably disposed on the fixed bracket 210 , the light-emitting screen of the projector 220 faces the display curtain 320 , and the fixed bracket 210 is detachably clamped on the base 100 .

[0035] Compared with the electronic screen of the prior art, the conference intelligent interactive machine 10 of the present invention is compact and does not occupy too much desktop space. Moreover, the conference intelligent interactive machine 10 of the present invention has two states: idle state (such as Figure 4 as shown) and usage status (as shown Figure 5 shown);

[0036] Initially, the conference intelligent interactive machine 10 is in an idle state. In this state, the display curtain 320 is completely rolled up on the rotating shaft 310, the two telescopic rods 340 are also folded and accommodated in the base 100, and the support beam 330 connected to the telescopic rods 340 is also covered on the base 100. The conference intelligent interactive machine 10 in the idle state is small in size and low in height, and it is not easy to block the vision of the participants;

[0037] When in use, the user only needs to pull up the support beam 330, and the support beam 330 will rise with the display curtain 320 and the telescopic rod 340 (such as Figure 2 and Figure 5 As shown). At this time, the rotating shaft 310 unwinds the display curtain 320, and the torsion spring accumulates elastic potential energy. The rotating shaft 310 always maintains the reeling tension on the display curtain 320, which allows the display curtain 320 to remain flat after being pulled out. At the same time, the telescopic rod 340 is stretched, and its internal volume (space) increases and forms a negative pressure. The external gas will pass through the one-way valve 120 and the gas supply channel 101 in turn into the telescopic rod 340 to achieve filling; because the one-way valve 120 only allows gas to flow in one direction, the gas entering the interior of the conference intelligent interactive machine 10 will not be discharged, so that the telescopic rod 340 will remain in an stretched state (i.e., in use). In other words, although the torsion spring has elastic potential energy at this time, due to the obstruction of the telescopic rod 340, the display curtain 320 will remain unfolded and cannot be reeled, that is, the conference intelligent interactive machine 10 is in use at this time;

[0038] Then, the podium demonstration screen transmits the signal to the projector 220, and the projector 220 tilts and projects the content of the demonstration on the podium toward the display screen 320, thus solving the problem that the participants cannot see the demonstration content clearly;

[0039] After use, the user only needs to "unlock" the two one-way valves 120 so that the one-way valves 120 no longer prevent the gas from flowing in the opposite direction, thereby achieving mutual circulation of gas inside and outside the device. In this way, under the pulling force of the rotating shaft 310, the display curtain 320, the telescopic rod 340 and the support beam 330 will drop together, the display curtain 320 will be rolled up, the telescopic rod 340 will be folded, and the gas in the telescopic rod 340 will also be discharged to the outside.

[0040] It should be emphasized that the setting of the rotating shaft 310 plays a key role in the present invention: first, the display screen 320 cooperates with the rotating shaft 310 to realize the winding storage mode. Compared with the folding storage mode, the winding storage mode can keep the surface of the display screen 320 smooth and avoid wrinkles on the display screen 320 after multiple storages; secondly, the rotating shaft 310 is set on the base 100 through the torsion spring. When the display screen 320 is unwound, the torsion spring accumulates elastic potential energy, and the rotating shaft 310 always keeps the display screen 320 in a stable state. The display screen 320 has a tensile force, and the tensile force is evenly distributed on the display screen 320, which enables the display screen 320 to remain flat after being unfolded without being loose; in addition, the tensile force provided by the rotating shaft 310 also provides power for the subsequent folding of the display screen 320. After the one-way valve 120 is "unlocked", the telescopic rod 340 can be compressed, and the display screen 320 and the telescopic rod 340 can be automatically recovered under the action of the tensile force, thereby providing convenience for users.

[0041] In order to realize the function of the one-way valve 120 described above, the present invention makes a special design for the one-way valve 120, as follows.

[0042] like Figure 6 As shown, the one-way valve 120 includes: a valve body 121 , an isolation sheet 122 , a positioning frame 123 , and a return spring 124 . The valve body 121 is provided with an air hole 102 and an air cavity 103 . The air hole 102 is connected to the air delivery channel 101 through the air cavity 103 .

[0043] The isolation piece 122 and the positioning frame 123 are both installed in the air cavity 103 of the valve body 121 . A pressure spring 125 is provided between the positioning frame 123 and the isolation piece 122 . The isolation piece 122 blocks the air hole 102 under the supporting action of the pressure spring 125 .

[0044] The valve body 121 is arranged on the base 100 through a return spring 124. The base 100 is provided with an exhaust hole 104. The side wall of the valve body 121 is provided with an air leakage hole 105 that matches the exhaust hole 104. The air leakage hole 105 is communicated with the air cavity 103. A blocking ring 126 is arranged on the valve body 121. The return spring 124 pushes the blocking ring 126 to resist and block the exhaust hole 104.

[0045] The working principle of the one-way valve 120 is described below:

[0046] When the display curtain 320 is unfolded and the telescopic rod 340 is stretched, the internal space of the telescopic rod 340 increases and forms a negative pressure, and the external gas pushes the isolation plate 122 under the action of pressure. At this time, the pressure spring 125 is compressed, and the isolation plate 122 no longer blocks the air hole 102, so the external gas enters the gas transmission channel 101 through the air hole 102 and the air cavity 103, and finally fills the interior of the telescopic rod 340;

[0047] When the telescopic rod 340 is pulled by the rotating shaft 310, the gas inside the telescopic rod 340 cannot escape to the outside because the isolation sheet 122 blocks the air hole 102. Therefore, the pressure of the gas prevents the telescopic rod 340 from being folded, so that the telescopic rod 340 and the display curtain 320 remain in the use state;

[0048] When the display curtain 320 needs to be folded, the user only needs to press the two one-way valves 120 on both sides of the base 100 to make the valve body 121 slide relative to the base 100 (i.e., "unlocking" the one-way valve 120 as described above). At this time, the return spring 124 is compressed, and the blocking ring 126 of the valve body 121 no longer blocks the exhaust hole 104. The telescopic rod 340 is folded by the pulling force of the rotating shaft 310, and the internal space of the telescopic rod 340 is reduced. Under the action of pressure, the gas inside will pass through the gas transmission channel 101, the air cavity 103, and the air leakage hole 105 in turn, and finally be discharged to the outside from the exhaust hole 104. In this way, the telescopic rod 340 can be folded smoothly, and the conference intelligent interactive machine 10 changes back to the idle state.

[0049] It is worth mentioning that the telescopic rod 340 can only be recovered when the two one-way valves 120 are "unlocked" together. If only the one-way valve 120 on one side is pressed, the telescopic rod 340 corresponding to that side can be retracted, while the telescopic rod 340 on the other side cannot be retracted because the internal gas cannot escape. This design can avoid the situation where the display curtain 320 is rolled up due to errors. When the one-way valve 120 on one side is "unlocked" by the error, the display curtain 320 can still be maintained in the unfolded state with the support of the telescopic rod 340 on one side; after accidentally letting go, the one-way valve 120 affected by the error can be reset in time and return to the state of being supported by the telescopic rods 340 on both sides. Only when the one-way valves 120 on both sides are pressed together to "unlock" can the display curtain 320 and the telescopic rod 340 be smoothly recovered to the idle state.

[0050] Preferably, the spacer 122 is made of a PU material, and the valve body 121 is made of a copper alloy material. The spacer 122 made of a PU material can have both the rigidity of plastic and the elasticity of rubber, that is, it can fit tightly with the inner wall of the valve body 121 when blocking the air hole 102, and is not prone to serious deformation after long-term use, thereby achieving good air tightness.

[0051] In this embodiment, the display screen 320 is made of a transparent material, and an electrochromic film 350 is attached to the display screen 320. The electrochromic film 350 can remain transparent when not powered, and will "fog" to present an opaque state after power is supplied. The conference intelligent interactive machine 10 of the present invention utilizes this feature of the electrochromic film 350, so that the display screen 320 can present two different styles of transparent and opaque during use, so as to play different functions and improve the efficiency of conference communication.

[0052] For example, when the meeting is in the demonstration phase, the display screen 320 of the conference intelligent interactive machine 10 changes to an opaque state, and the projection device 200 can project the content demonstrated on the podium onto the display screen 320, so that the participants can see the content clearly, thereby realizing positive interaction; when the meeting is in the problem feedback phase, the display screens 320 of all conference intelligent interactive machines 10 change to a transparent state, and the participants who have no problem to feedback can project a specified color (for example, green) on the display screen 320, and the participants who have problems to feedback can project another specified color (for example, red) on the display screen 320. Since the display screen 320 is transparent, the color of the light refracted by the display screen 320 can be directly observed on the podium, so that it can clearly and quickly know which participants have the need to feedback problems, thereby realizing reverse interaction.

[0053] Preferably, the structure of the electrochromic film 350 can refer to the Chinese utility model patent with publication number CN201222152Y and the name “Flexible electrochromic film”. Figure 7 As shown, the electrochromic film 350 includes two flexible substrate layers 351, a color-changing layer 352, an ion conductor layer 353, an ion storage layer 354, and two conductive layers 355. Both conductive layers 355 are provided with extraction electrodes 356. The color-changing layer 352, the ion conductor layer 353, and the ion storage layer 354 are sandwiched in the two conductive layers 355. The two flexible substrate layers 351 are respectively located on the outside of the two conductive layers 355. When power is turned on to issue a command, the ion storage layer 354 stores and releases corresponding ions, and the color-changing layer 352 changes color, so that the electrochromic film 350 is "atomized" and becomes opaque.

[0054] In one embodiment, a writing board 130 (eg, Figure 1 As shown in FIG. 3 , the writing board 130 and the projection device 200 are respectively located on both sides of the display screen 320. When in use, the writing board 130 can be used to write the name of the participant at this seat so that the participant knows it.

[0055] In summary, the conference intelligent interactive machine 10 of the present invention can take into account the characteristics of small size and clear display, thereby avoiding blocking the field of vision of participants and avoiding excessive occupation of desktop space; at the same time, it realizes two-way interaction, which is conducive to improving the efficiency of conference communication.

[0056] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
