[0034] See Figures 1-8 As shown, this utility model provides an intelligent lectern, which includes a base 1, a tabletop 2, a ladder 100, a lighting component 200, and a drive component 300. The tabletop 2 is fixed above the base 1. The ladder 100 is located above the tabletop 2, and its rear end has an inclined surface 1802 and a recessed groove 1801 at its upper end. A monitoring screen 4 and a photoelectric switch 3 located around the monitoring screen 4 are provided on the inclined surface 1802. The lighting component 200 has a first position embedded in the recessed groove 1801 and a second position located above the ladder 100. The drive component 300 is located inside the ladder 100 and can drive the lighting component 200 to move between the first position and the second position. The photoelectric switch 3 is used to control the operation of the drive component 300.

[0035] In this invention, when the photoelectric switch 3 is not blocked by an object above it, the lighting component 200 is in the first position and the lamp beads on the lighting component 200 are not lit; when the photoelectric switch 3 detects that it is blocked by an object above it, the driving component 300 drives the lighting component 200 to move from the first position to the second position, and the lamp beads on the lighting component 200 light up, the lighting component 200 emits light and illuminates the paper speech manuscript placed on the inclined surface 1802.

[0036] See Figure 2 and Figure 4As shown, the ladder platform 100 in this embodiment is mainly composed of a surrounding plate 17 and a bent plate 18. The surrounding plate 17 is roughly U-shaped. The bottom of the surrounding plate 17 is fixedly connected to the edge of the platform 2. The bent plate 18 is located above the platform 2. The edge of the bent plate 18 is fixedly connected to the surrounding plate 17 and the platform 2. The horizontal part of the bent plate 18 forms the top surface of the ladder platform 100, and the inclined part of the bent plate 18 forms the inclined surface 1802 of the ladder platform 100. The surrounding plate 17, the bent plate 18 and the platform 2 together form a cavity for accommodating the drive assembly 300.

[0037] See Figures 5 to 7 As shown, in this embodiment, the drive assembly 300 includes a support arm 5, a slide rail 6, a drive shaft 7, a gear 8, and a motor 9. The upper end of the support arm 5 is fixedly connected to the lighting assembly 200, and the support arm 5 is provided with teeth. The upper end of the slide rail 6 is fixedly connected to the platform 100, the lower end of the slide rail 6 is fixedly connected to the table surface 2, and the lower end of the support arm 5 is slidably connected to the slide rail 6. The drive shaft 7 is horizontally arranged and rotatably connected to the slide rail 6. The gear 8 is provided on the drive shaft 7 and meshes with the teeth on the support arm 5. The motor 9 is connected to the drive shaft 7 through a transmission mechanism and drives the drive shaft 7 to rotate. The motor 9 is connected to the photoelectric switch 3.

[0038] like Figure 7 As shown, there are two support arms 5, two slide rails 6, and two gears 8. The aforementioned transmission mechanism includes a drive pulley 19 mounted on the motor 9 and a driven pulley 20 mounted on the transmission shaft 7. The drive pulley 19 and the driven pulley 20 are connected by a belt 21. When the motor 9 rotates, it can drive the transmission shaft 7 to rotate, and then the gear 8 will drive the support arm 5 to slide along the slide rail 6.

[0039] See Figure 5 and Figure 8 As shown, in order to achieve a sliding connection between the support arm 5 and the slide rail 6, the slide rail 6 is provided with a slide groove 601, the lower end of the support arm 5 is provided with two shafts 10, one end of the shafts 10 is provided with a roller 11, the roller 11 is located in the slide groove 601 and can roll in the slide groove 601.

[0040] See Figure 5 and Figure 6 As shown, the slide 601 and the support arm 5 are concentric arcs, with the center of the slide 601 and the monitoring screen 4 located on the same side of the slide 601. Figure 6 As shown, when the lighting component 200 moves to the second position, the light-emitting surface on the lighting component 200 faces the inclined plane 1802, which helps to illuminate more objects (such as paper manuscripts) placed on the inclined plane 1802.

[0041] See Figure 5As shown, the smart lectern also includes a stop plate 12 connected to the lower edge of the inclined surface 1802. When a speech is placed on the inclined surface 1802, the bottom of the speech contacts the stop plate 12, which prevents the speech placed on the inclined surface 1802 from sliding downward.

[0042] In this embodiment, the photoelectric switch 3 is positioned between the monitoring screen 4 and the stop plate 12, so that no matter how large the presentation slide is placed on the inclined surface 1802, the slide will block the photoelectric switch 3. The photoelectric switch 3 in this invention can also be replaced by a through-beam infrared sensor and a control module (microcontroller) electrically connected to the through-beam infrared sensor.

[0043] In this embodiment, a display screen 13 is provided at the front end of the base 1. The display screen 13 can be an LCD screen and can be used to display information such as the speaker's personal introduction and the topic of the speech. A touch screen 14 and a microphone 15 are provided on the tabletop 2. The touch screen 14 is used to control the intelligent lectern, such as turning pages of information displayed on the monitor screen 4, selecting / inputting information displayed on the display screen 13, and adjusting the volume in conjunction with the external speakers. A microphone 15 is provided on each side of the touch screen 14, and the microphones 15 are connected to the sound reinforcement system (speakers). The lower end of the base 1 is provided with multiple casters 16, which facilitate the movement of the intelligent lectern and make it more convenient to use.

[0044] In some embodiments, the base 1 includes a housing 101 and two electric lifting columns 102. The bottom of the electric lifting columns 102 is fixedly connected to the housing 101. A lifting button 22 is provided on the platform 2. The speaker can adjust the height of the smart lectern according to their own height by using the lifting button 22, so that the smart lectern can be suitable for speakers of different heights.

[0045] In this invention, a USB interface can be installed on the intelligent lectern to read or copy the speech content prepared by the speaker from a USB flash drive, and display the speech content on the monitoring screen 4. When the speaker prepares a paper speech, the speaker can place the paper speech on the inclined surface 1802 of the platform 100. After the photoelectric switch 3 detects that a paper speech is placed on the inclined surface 1802, the driving component 300 drives the lighting component 200 to move to the second position, and the lighting component 200 emits light to illuminate the speech, allowing the standing speaker to read the speech at a suitable angle. After the speech, when the speaker removes the paper speech from the inclined surface 1802, the driving component 300 drives the lighting component 200 to move to the first position, and the LEDs on the lighting component 200 turn off.

[0046] The intelligent lectern provided by this utility model can not only display the speech content on the monitor screen 4, but also place printed paper manuscripts. Most importantly, when the intelligent lectern is used to place paper manuscripts, the lighting component 200 can automatically extend to a suitable position to provide good lighting for the paper manuscript, facilitating the speaker's reading. Furthermore, the lighting component 200 automatically extends when the paper manuscript is placed on the inclined surface 1802 and automatically retracts when the paper manuscript is removed from the inclined surface 1802, achieving automatic extension and retraction of the lighting component 200, making it more convenient to use. When not in use, the lighting component 200 is located in the recess 1801, with its upper end flush with the upper end of the platform 100, resulting in a simpler, more aesthetically pleasing design and easier cleaning.
