Description

Technical Field

[0001] This disclosure relates to the fields of intelligent teaching and smart screen products, and in particular to a multifunctional lectern and intelligent teaching device based on a smart screen system. Background Technology

[0002] With social development and technological advancements, the education sector has gradually gained more attention. The completeness of various teaching equipment directly impacts the quality of instruction students receive. To enable students to receive a better education, intelligent lecterns (or multifunctional lecterns) are indispensable teaching tools.

[0003] Currently, some lecterns consist of a lectern body and an LCD or touchscreen display, with the LCD or touchscreen display either mounted on the lectern body or embedded within it, such as the multi-functional teaching lectern disclosed in existing patent CN203789423U. This results in a relatively fixed viewing angle for the computer or touchscreen display. Due to differences in the height of different lecturers, the angle at which their eyes look at the display also varies, making it difficult for existing multi-functional lecterns to adequately meet the needs of different lecturers. For example, taller lecturers (e.g., 1.8 meters tall) are forced to view the screen in an unnatural posture (bending over or looking up). Furthermore, while some smart lecterns are equipped with facial recognition or image capture functions (such as attendance and identity authentication), the fixed-angle display may prevent the camera from being directly facing the lecturer's face, affecting recognition accuracy and response speed. These issues will impact the lecturer's user experience and teaching effectiveness. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a multifunctional lectern and smart teaching device based on a smart screen system that can automatically adjust the display angle according to the image acquisition status.

[0005] The purpose of this disclosure is achieved through the following technical solution:

[0006] A multi-functional lectern based on a smart screen system includes a lectern body and a multi-functional display. The multi-functional display is mounted on the lectern body and includes a main unit box, a motherboard, an angle adjustment mechanism, and a display screen. The main unit box is mounted on the lectern body, and the motherboard is located inside the main unit box. The display screen includes a display screen body and an image sensor, with the image sensor mounted on the display surface of the display screen body. The angle adjustment mechanism includes a first adjustment motor, a first swing arm, a transition rod, a second adjustment motor, and a second swing arm.

[0030] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0031] Please see Figure 1 The present invention is a multifunctional lectern 10 based on a smart screen system, which includes a lectern body 100 and a multifunctional display 200, the multifunctional display 200 being disposed on the lectern body 100.

[0032] like Figures 2 to 6 As shown, the multi-functional display 200 includes a main unit box 210, a motherboard 220, an angle adjustment mechanism 230, and a display screen 240. The main unit box 210 is mounted on the podium body 100, and the motherboard 220 is located inside the main unit box 210. The display screen 240 includes a display screen body 241 and an image sensor 242, with the image sensor 242 mounted on the display surface of the display screen body 241. The angle adjustment mechanism 230 includes a first adjustment motor 231, a first swing arm 232, a transition arm 233, a second adjustment motor 234, and a second swing arm 235. The first adjustment motor 231 is mounted on the main unit box 210. One end of the first swing arm 232 is connected to the drive shaft of the first adjustment motor 231. Specifically, one end of the first swing arm 232 is fixedly connected to the drive shaft of the first adjustment motor 231, and the other end of the first swing arm 232 is fixedly connected to the transition arm 233. The second adjustment motor 234 is mounted on the transition arm. On 233, one end of the second swing arm 235 is connected to the drive shaft of the second adjustment motor 234. Specifically, one end of the second swing arm 235 is fixedly connected to the drive shaft of the second adjustment motor 234, and the other end of the second swing arm 235 is fixedly connected to the display screen body 241. The display output terminal of the main board 220 is electrically connected to the display screen body 241, the acquisition terminal of the image sensor 242 is electrically connected to the acquisition signal receiving terminal of the main board 220, one drive control terminal of the main board 220 is electrically connected to the first adjustment motor 231, and the other drive control terminal of the main board 220 is electrically connected to the second adjustment motor 234, so that the main board 220 drives the first adjustment motor 231 and / or the second adjustment motor 234 to start according to the acquisition information of the image sensor 242, so as to swing the first swing arm 232 and / or the second swing arm 235, thereby driving the display screen 240 to rotate a certain angle, thereby adjusting the display direction of the display screen body 241.

[0033] In this embodiment, as Figure 7As shown, the motherboard 220 has an image recognition module 221, an image reference module 222, and an image comparison module 223. The image recognition module 221 and the image reference module 222 are electrically connected to the comparison end and the comparison end of the image comparison module 223, respectively. The data acquisition output end of the image sensor 242 is electrically connected to the receiving end of the image recognition module 221. The image comparison module 223 is used to compare whether the face information read by the image recognition module 221 matches the face information of the image reference module 222, that is, whether the image sensor 242 has fully captured the lecturer's face.

[0034] It is understandable that when the lecturer uses the multi-functional lectern 10, their eyes are aligned with the image sensor 242. The image sensor 242 acquires facial image information and feeds this information back to the image recognition module 221 on the motherboard 220. The image comparison module 223 compares the facial information from the image reference module 222 with the current facial information from the image recognition module 221. If they do not match, it indicates that the image sensor 242 has not fully captured the lecturer's face. Then, depending on the captured face position, it drives either the first adjustment motor 231, the second adjustment motor 234, or both simultaneously, until the image sensor 242 can fully capture the lecturer's face. Furthermore, when the image sensor 242 does not fully capture the lecturer's face, the image mapped onto the main display screen 241 only shows the upper or lower half of the face.

[0035] Furthermore, such as Figure 7 As shown, the motherboard 220 also has a motor control module 224. The comparison output terminal of the image comparison module 223 is electrically connected to the signal receiving terminal of the motor control module 224. One drive enable terminal of the motor control module 224 is electrically connected to the first regulating motor 231, and the other drive enable terminal of the motor control module 224 is electrically connected to the second regulating motor 234, so that the motor control module 224 has a first control state, a second control state, and a third control state. The first control state is to enable only the first regulating motor 231, the second control state is to enable only the second regulating motor 234, and the third control state is to enable both the first regulating motor 231 and the second regulating motor 234.

[0036] Furthermore, when only the second adjustment motor 234 is driven to work to adjust the display angle of the display screen body 241, the distance between the transition rod 233 and the human body remains unchanged; when only the first adjustment motor 231 is driven to work, or when both the first adjustment motor 231 and the second adjustment motor 234 are driven simultaneously to adjust the display angle of the display screen body 241, the distance between the transition rod 233 and the human body changes.

[0037] In the above embodiments, the multifunctional lectern 10 based on the smart screen system adopts an angle adjustment mechanism 230 and an image sensor 242. That is, after the image sensor 242 collects the position of the person, it controls the first adjustment motor 231 and / or the second adjustment motor 234 to start according to the collected information, so that the first swing arm 232 and / or the second swing arm 235 swings at a certain angle, thereby driving the display screen body 241 to rotate at a certain angle until the sensing area of ​​the image sensor 242 can cover the entire face of the lecturer, that is, the display surface of the display screen body 241 is facing the lecturer's face. In this way, the multifunctional lectern 10 can be well adapted to the usage needs of different lecturers.

[0038] like Figure 3 As shown, in one embodiment, the display screen 240 further includes a touch screen component 243, which is mounted on one side of the display screen body 241. In this embodiment, the touch screen component 243 includes a stylus 2431 and a placement plate 2432. The placement plate 2432 is connected to one side of the display screen body 241, and the stylus 2431 is movably mounted on the placement plate 2432. It can be understood that when an instructor uses the display screen body 241 to teach, if they need to operate the display screen body 241, the instructor can take the stylus 2431 from the placement plate 2432 to perform touch screen operations. When not using the stylus 2431, it can be placed back on the placement plate 2432, which makes using the stylus 2431 more convenient. Furthermore, the placement plate 2432 has a receiving slot 243a, in which the stylus 2431 is movably mounted. Thus, when the stylus 2431 is not in use, it can be placed in the receiving slot 243a to prevent it from suddenly slipping off the placement plate 2432. In a preferred embodiment, the stylus 2431 is magnetically disposed in the receiving slot 243a.

[0039] like Figure 1 As shown, in one embodiment, the multi-functional lectern 10 further includes a central control touchscreen panel 300, which is disposed on the lectern body 100 and is communicatively connected to the motherboard 220. It can be understood that when the central control touchscreen panel 300 is provided, the display angle of the display screen body 241 can be adjusted by operating the central control touchscreen panel 300 to control the first adjustment motor 231 and / or the second adjustment motor 234, and the display screen body 241 can also be turned on or off by operating the central control touchscreen panel, as well as the image sensor 242 can be turned on or off by operating the central control touchscreen panel.

[0040] like Figure 5 or Figure 6As shown, in one embodiment, the second swing arm 235 is perpendicular to the display screen body 241, that is, the center line of the second swing arm 235 forms a 90° angle with the center line of the display screen 240.

[0041] like Figure 5 As shown, in one embodiment, the host box 210 has a data port 211 on its side, which is electrically connected to the data transmission terminal of the motherboard 220. Thus, when the data port 211 is provided, the user can connect external devices to the host box 210 via a cable to enable data interaction or communication between the external devices and the host box 210, improving the interactivity of the multi-functional display 200. Furthermore, the data port 211 includes a USB port 2111, an HDMI port 2112, and a Type-C port 2113, all of which are electrically connected to the data transmission terminal of the motherboard 220. This provides the host box 210 with a rich variety of data ports 211, allowing connection to various types of external devices. For example, the HDMI port 2112 supports high-definition video transmission and provides clear image quality, and can be used to connect to a projector so that students can view the content displayed on the projector; the USB port 2111 can connect to various types of universal devices, such as USB flash drives, mice, keyboards, etc.; the Type-C port 2113 supports reversible insertion and can be used to connect USB flash drives, communication devices, etc.

[0042] like Figure 3 As shown, in one embodiment, the host box 210 has a network port 212 on its side, which is electrically connected to the network port of the motherboard 220. Thus, users can connect to the network port 212 via a network cable to achieve system networking.

[0043] Combination Figure 1 and Figure 4 As shown, in one embodiment, the multi-function display 200 also includes an anti-slip pad 250, which is disposed at the bottom of the main unit box 210 so that the anti-slip pad 250 abuts against the lectern body 100, thereby preventing the main unit box 210 from rubbing against the lectern body 100 and causing surface wear. The anti-slip pad 250 also prevents the main unit box 210 from sliding on the lectern body 100.

[0044] This disclosure also provides a smart teaching device, including a multi-functional lectern 10 based on a smart screen system according to any of the above embodiments.

[0045] Compared with the prior art, this disclosure has at least the following advantages:

[0046] The aforementioned multi-functional lectern 10 based on the smart screen system employs an angle adjustment mechanism 230 and an image sensor 242. The image sensor 242 collects the position of the person and, based on the collected information, controls the first adjustment motor 231 and / or the second adjustment motor 234 to start. This causes the first swing arm 232 and / or the second swing arm 235 to swing at a certain angle, thereby rotating the display screen body 241 at a certain angle until the sensing area of ​​the image sensor 242 covers the lecturer's entire face, meaning the display surface of the display screen body 241 is directly facing the lecturer's face. This allows the multi-functional lectern 10 to well adapt to the usage needs of different lecturers.

[0047] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
