Description

Technical Field

[0001] The utility model relates to the technical field of liftable lecterns, in particular to an integrated multi-functional intelligent liftable lectern. Background Art

[0002] A lectern, also called a podium, is a table used by speakers. It is mostly integrated with devices such as microphones and computers. When a speaker is giving a speech, the speech script needs to be placed on the lectern for the speaker to view, making the speaker's speech process smoother.

[0003] The following technical problems exist in the conference lecterns in the prior art:

[0004] 1. Currently, most of the lecterns in the conference field have a fixed or simple liftable height, and the different heights of the speakers cause great inconvenience when speaking and facing the conference participants.

[0005] 2. On large conference platforms and stages, due to the different heights of the speakers, when looking at the speech script, the top lighting causes unclear vision and dizziness in the eyes, resulting in speech mistakes.

[0006] 3. Currently, the lecterns in the conference field are heavy and not convenient to move. Therefore, it takes a lot of manpower and time to arrange them on the conference platform;

[0007] 4. There is no built-in preset program. All speakers need to understand the operation method of the lectern in advance, which consumes a certain amount of time in the early stage. At the same time, when about to speak, in necessary cases, the speaker needs to adjust the appropriate desktop height immediately, which will waste a lot of time, affect the speaker's performance and affinity with the participants, and there are also misoperations; the existing lecterns can preset multiple height intervals. When the speaker is about to go onto the lectern, the backstage staff can set the preset position or timely height data through the remote control to adjust the appropriate desktop height.

[0008] 5. The speech manuscripts are either held by hand, placed horizontally on the lectern, or placed on a fixed-angle page-turning platform. Currently, the speech manuscripts are placed horizontally on the desktop or on a desktop with an unadjustable angle. For people of different heights, it is difficult to present the best visual angle to meet the need to read the manuscript content, and even the manuscript content cannot be clearly read due to the top lighting. At the same time, most of the existing fixed-angle page-turning platforms cannot adjust the angle of the manuscript according to personal habits, resulting in poor viewing for the speaker and thus affecting the speech effect.

[0043] Example, as Figure 1 As shown, the present invention provides an integrated multifunctional intelligent lifting podium, including a four - unit microphone 1, a page - turning platform 2, a lifting control system 3, and a podium 4. Among them, the composition of the page - turning platform 2 is as Figure 4 shown, including a manuscript support plate 21, a spring hinge sub - part 22, a spring hinge mother - part 210, a connecting seat 23, a shaft support seat 24, a nylon gear 25, an adjustment knob 26, a transmission rotating shaft 27, a page - turning platform base 28, a lifting circular arc rack 29, and an anti - slip pad 211.

[0044] Among them, the composition of the lifting control system 3 is as Figure 2 shown, including a screen display remote control 31, an intelligent synchronous control screen 32, a lifting device 33, and a driver 34.

[0045] Among them, the composition of the podium 4 is as Figure 2 shown, including a lifting table body 41, a base 42, and universal wheels 43. The lifting table body 41 includes a tabletop 411, a workbench surface 412, a side drawer 413, an intermediate drawer 414, and an inspection door 415; the universal wheels 43 are composed of 2 universal wheels and 2 brake - equipped universal wheels (not marked in the figure) each.

[0046] The specific implementation principle is as follows:

[0047] As Figure 4As shown in the figure, the spring hinge sub-component 22 is fixed to the tail of the manuscript support plate 21. Three connecting seats 23 are fixed to the lower side of the manuscript support plate 21. The shaft support seat 24 is fixed to the connecting seat 23. The transmission rotating shaft 27 passes through the shaft support seats 24 respectively. Both ends of the transmission rotating shaft 27 are small-diameter steps, so as to limit the axial movement of the transmission rotating shaft 27. Being fixed on the shaft support seat 24 can prevent left and right movement. At the same time, one nylon gear 25 is installed in the interval between two or three shaft support seats 24. Two nylon gears 25 are sleeved on the transmission rotating shaft 27, and the nylon gears 25 and the transmission rotating shaft 27 are fixed in the corresponding positions by set screws. One end of the transmission rotating shaft 27 penetrates through the side of the manuscript support plate 21, and the adjustment knob 26 is fixed to one side of the transmission rotating shaft 27 by a set screw; the adjustment knob 26 and the two nylon gears 25 are fixed on the transmission rotating shaft 27 at the same time, and can maintain relative static while moving simultaneously. The page-turning table base 28 is placed horizontally on the tabletop. The spring hinge female component 210 is fixed to the tail of the page-turning table base 28. The lifting arc-shaped rack 29 is fixedly installed at the head of the page-turning table base 28. When installed, the center of the spring hinge female component 210 coincides with the center of the pitch circle of the lifting arc-shaped rack 29.

[0048] After the installation is completed, as Figure 3 shown in the figure, where the spring hinge sub-component 22 and the spring hinge female component 210 are assembled into the finished product component spring hinge, and a total of 2 are installed. The spring hinge has a certain torque. After the manuscript support plate 21 and the page-turning table base 28 are installed, the page-turning table base 28 is placed on the horizontal table and remains stationary. When applying force up and down on the manuscript support plate 21, it can move up and down along the lifting arc-shaped rack 29, and there will be a certain gravity moment during the up and down movement of the manuscript support plate 21. The spring hinge can neutralize the gravity moment of the manuscript support plate 21, and the manuscript support plate 21 can freely stop at any position of the lifting arc-shaped rack 29.

[0049] At the same time, rotate the adjustment knob 26, and the two nylon gears 25 rotate simultaneously. The two nylon gears 25 rotate along the lifting arc-shaped rack 29 to drive the manuscript support plate 21 to move up and down. The lower end of the shaft support seat 24 is provided with a shaft hole, and the shaft hole is provided with an opening at the position, and an adjustment screw is provided at the opening. The tightness of the adjustment screw can change the size of the shaft hole, so that the pressure between the shaft hole of the shaft support seat 24 and the shaft surface of the transmission rotating shaft 27 can be increased, thereby increasing the friction force to play a damping role, so as to meet the requirement that a certain force can be borne on the inclined surface of the manuscript support plate 21. And the adjustment knob 26 can be rotated so that the manuscript support plate 21 can be adjusted by a certain angle at the original fixed angle to meet the use requirements of different scenarios.

[0050] As Figure 2As shown in the figure: The intelligent synchronization control panel 32 in the lifting control system 3 is installed and fixed on the middle drawer 414. Four hole positions on the upper plane of the lifting device 33 are fixed on the support plate in the lifting table body 41 by screws, and four hole positions on the lower plane of the lifting device 33 are fixed on the support plate in the base 42 by screws.

[0051] The driver 34 is fixed in the base 42 by screws. The driver 34 is externally connected with a power supply line. The driver 34 is connected to two lifting devices 33 and the intelligent synchronization control panel 32 through signal lines and power supply lines respectively. The intelligent synchronization control panel 32 can set the synchronous lifting and lifting speed of the two lifting devices 33, drive the lifting and lowering of the lifting table body 41 through the lifting device 33 and can display the height position parameters in real time. At the same time, multiple person names and corresponding height position parameters can be preset, and the height position of the lifting device 33 can be controlled by touching the preset person name or serial number in the intelligent synchronization control panel 32. At the same time, the screen display remote controller 31 can also synchronously display the preset person name or serial number in the synchronization control panel 32 and directly click to control, or can be controlled to rise and fall in real time through the up and down arrow keys.

[0052] As Figure 1 shown in the figure: When the speaker walks to the middle of the intelligent lifting podium and faces the four-unit microphone 1, after the speech manuscript is placed on the page-turning platform 2, the staff can use the screen display remote controller 31 to control the lifting of the lifting table body 41 according to the options of the preset personnel so as to meet the preset height position parameters. At the same time, the speaker rotates the adjustment knob 26 to control the lifting of the manuscript support plate 21 according to the current light environment, so that the speech manuscript has a suitable angle, enabling the speaker to have the best visual angle and clearly read the content of the manuscript, achieving the effect of the speech.

[0053] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention; without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
