[0025] DETAILED DESCRIPTION

[0026] In order to facilitate understanding of the present application, the present application is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification and in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0028] The present application provides an intelligent teaching aid 1000, which aims to improve the current situation where users need to turn pages at the projector and annotate and explain in front of the screen. The frequent movement increases the user's academic burden and reduces classroom efficiency.

[0029] See also Figure 1 and Figure 2The intelligent teaching aid 1000 includes a shell 100, a display mechanism 200 and a projection mechanism 300. The shell 100 includes a panel 110 and a top plate 120, and the top plate 120 is installed on the panel 110. The display mechanism 200 includes a carrier plate 210, and the carrier plate 210 and the top plate 120 are arranged relative to the panel 110. The projection mechanism 300 includes a camera component 310 and a display 320, and the camera component 310 is installed on the top plate 120, wherein the camera component 310 is used to capture images of objects located on the carrier plate 210, and the display 320 is installed on the panel 110, and the display 320 is used to display the images captured by the camera component 310. Through the above structure, the user can place the objects to be displayed on the carrier plate 210, and the image of the objects to be displayed is captured by the camera component 310 and displayed on the display 320. This allows users to annotate, turn pages, and explain content directly on the intelligent teaching aid 1000 without having to constantly move between the intelligent teaching aid 1000 and other devices, thereby reducing the workload and improving classroom efficiency. Furthermore, the presence of the display 320 allows users to view annotations and images captured by the camera assembly 310 by simply looking at the display 320 while writing, without having to turn or lower their heads.

[0030] In some embodiments, the panel 110 is arranged along a first direction F1. Along the first direction F1, the supporting plate 210 and the top plate 120 are arranged at opposite ends of the panel 110. The surface of the supporting plate 210 forms a first angle with the surface of the panel 110, and the display 320 forms a second angle with the surface of the supporting plate 210. It should be noted that the first angle and the second angle can be equal or unequal. When the first angle and the second angle are equal, the display 320 is parallel to the surface of the panel 110 and is recessed relative to the panel 110, thereby preventing damage to the display 320. When the first angle and the second angle are unequal, preferably, the second angle is greater than the first angle, so that the display 320 is arranged at an elevated angle when in use for ease of use. The display 320 can also be configured as a touch-sensitive display 320, so that users can directly mark information in electronic files such as courseware on the display 320 without having to use other devices such as a mouse to modify it.

[0031] Although the above structure is configured with full consideration given to the different viewing angles of the user when observing the display 320 , thereby enabling selection of different second angles, the present application still provides a technical solution to further improve the user experience.

[0032] See also Figure 3 and Figure 4In the embodiment of the present application, the panel 110 is provided with an opening 111. The projection mechanism 300 further includes a mounting bracket 330, which is rotatably mounted to the opening 111 of the panel 110. The display 320 is mounted on the mounting bracket 330, and the display 320 is exposed in the opening 111. The second angle is further described in conjunction with the adjustable mounting bracket 330. The mounting bracket 330 is used to adjust the elevation angle between the display 320 and the surface of the support plate 210, where the elevation angle can be understood as the second angle mentioned above. Optionally, the second angle can be between 60° and 150°. Preferably, the second angle is 90°. It is understood that the second angle can be adjusted according to the height, standing height, and sitting height of different users. For example, when a user is standing to give a presentation, the second angle can be increased to facilitate viewing of the display 320; when a user is sitting to give a presentation, the second angle can be decreased to facilitate viewing of the display 320, thereby improving the user experience and reducing user fatigue. As for the above-mentioned display 320, the display 320 includes a lens, a display body, a pressing block and a buffer cotton, so as to further protect and fix the display 320.

[0033] For the above display mechanism 200, please refer to Figure 3 , and in conjunction with other drawings. The display mechanism 200 also includes a writing board 220 and a capacitive film 230. The writing board 220 and the supporting plate 210 together enclose a receiving cavity 240. The capacitive film 230 is received in the receiving cavity 240 and is disposed adjacent to the writing board 220. Specifically, the writing board 220 is disposed on a side of the supporting plate 210 close to the top plate 120, and the capacitive film 230 is mounted on a side of the writing board 220 facing the supporting plate 210. The capacitive film 230 feeds back an electronic signal to display the written handwriting on the display 320. Through the above structure, when the user is in use, he can use a capacitive pen or other objects that will not leave notes on the paper to write on the capacitive film 230 or the paper carried on the capacitive film 230. If there is a mistake or other situation that needs to be modified, the handwriting can be cleared to reduce the waste of paper; in addition, the above structure can also be combined with the above display 320 to directly annotate and modify electronic files such as courseware, reducing the inconvenience caused by the user switching devices and improving classroom efficiency; and, by setting up the capacitive film 230, it is convenient to collect the handwriting left by the user, so as to re-demonstrate the process of leaving the handwriting, for example: the teacher can explain the problem and leave handwriting, and re-demonstrate the teacher's problem-solving process, so that students can fully understand and digest the content of the problem.

[0034] In the examples of this application, please refer to Figure 2, and in combination with other drawings. The top plate 120 is also provided with a mounting plate surface 121, and the mounting plate surface 121 is tilted relative to the writing board 220 and / or the carrier plate 210. The camera assembly 310 includes a camera 311 and a light-equalizing plate 312, and the camera 311 and the light-equalizing plate 312 are both mounted on the mounting plate surface 121. The camera 311 is used to capture images of objects on the carrier plate 210, and the light-equalizing plate 312 is used to adjust the brightness of the objects on the carrier plate 210. It can be understood that the tilted mounting plate surface 121 can effectively increase the area in which the camera 311 can capture images. The light-equalizing plate 312 is used to fill in the light, thereby reducing the impact of external light on objects placed on the writing board 220 or the carrier plate 210.

[0035] In the examples of this application, please refer to Figure 4 , and in conjunction with other drawings. The display mechanism 200 also includes a rotating shaft assembly 250, which includes: a shaft body 251, a first self-locking member 252 and an elastic member 253. The shaft body 251 is arranged at one end of the supporting plate 210 close to the panel 110. The first self-locking member 252 is sleeved on the shaft body 251, and the first self-locking member 252 is provided with a self-locking protrusion 2521, which is used to fix the panel 110 and the supporting plate 210. One end of the elastic member 253 is connected to the end of the shaft body 251, and the other end is connected to the first self-locking member 252. The elastic member 253 is used to drive the first self-locking member 252 to slide relative to the shaft body 251. The housing 100 also includes a stop assembly 130, which includes a second self-locking member 131. At least a portion of the second self-locking member 131 is connected to the panel 110, while the other portion is sleeved on the shaft 251. The second self-locking member 131 is provided with a concave self-locking recess 1311. The second self-locking member 131 is rotatable relative to the first self-locking member 252 between a first preset position and a second preset position. In the first preset position, the self-locking protrusion 2521 abuts the inside of the self-locking recess 1311. In the second preset position, the self-locking protrusion 2521 abuts the outside of the self-locking recess 1311. This allows the intelligent teaching aid 1000 to switch between an expanded state and a stowed state. When the second self-locking member 131 is in one of the first and second preset positions relative to the first self-locking member 252, it corresponds to the expanded state; the other position corresponds to the stowed state. It is worth noting that at least a portion of the panel 110 is concave, thereby facilitating the accommodation of the carrier plate 210 and / or the writing tablet 220.

[0036] In some embodiments, the shaft 251 extends along the second direction F2, and the first self-locking member 252 is provided with a self-locking protrusion 2521 protruding along the second direction F2. The elastic member 253 is used to drive the first self-locking member 252 to slide relative to the shaft 251 along the second direction F2. The second self-locking member 131 is provided with a self-locking recess 1311 that is concave along the second direction F2. The second self-locking member 131 can rotate relative to the first self-locking member 252 along the second direction F2 between a first preset position and a second preset position. The second direction F2 is perpendicular to the first direction F1.

[0037] Understandably, see Figure 4 , and in conjunction with other figures. The shaft 251 can be mounted on the writing board 220 or the supporting plate 210, or clamped and fixed by the writing board 220 and the supporting plate 210. When the second self-locking member 131 rotates relative to the first self-locking member 252 about the second direction F2, the self-locking protrusion 2521 first abuts against the surface of the first self-locking member 252. Until the self-locking protrusion 2521 is opposite to the self-locking recess 1311, the elastic member 253 pushes or pulls the second self-locking member 131 toward the first self-locking member 252, causing the self-locking protrusion 2521 to abut against the self-locking recess 1311, thereby fixing the angle between the panel 110 and the writing board 220 and / or the supporting plate 210. Optionally, the elastic member 253 includes a tension spring, a compression spring, a spring, etc.

[0038] It is worth mentioning that see Figure 4 , and in combination with other drawings. The second self-locking member 131 can be rotated to a third preset position relative to the first self-locking member 252 around the second direction F2, thereby increasing the gear of the angle between the panel 110 and the writing board 220 and / or the supporting plate 210. On the one hand, it can play a damping role to prevent the writing board 220 and / or the supporting plate 210 from rotating rapidly and causing safety hazards. On the other hand, it can also increase the angles of different sizes between the panel 110 and the writing board 220 and / or the supporting plate 210, thereby increasing the use environment. In combination with the above-mentioned rotatable embodiment of the writing board 220 and / or the supporting plate 210, "there is a first angle between the board surface of the supporting plate 210 and the board surface of the panel 110" means that during the use of the intelligent teaching aid 1000, the angle between the supporting plate 210 and the panel 110 is set. Optionally, the first angle can be between 45° and 135°. Preferably, the first angle is 90°. The first angle between the carrier plate 210 and the panel 110 can be adjusted according to different usage scenarios, thereby increasing the space between the carrier plate 210 and the panel 110, making it easier to use other teaching aids for auxiliary teaching, such as teaching models, globes, etc.

[0039] Further, see Figure 4, and in conjunction with other drawings. The rotating shaft assembly 250 also includes a first limiting member 254, which is sleeved on the shaft body 251. The first limiting member 254 is further provided with a limiting notch 2541 along the circumference of the shaft body 251. The limiting assembly 130 also includes a second limiting member 132, which is at least partially fixed to the panel 110. Another portion of the second limiting member 132 is sleeved on the shaft body 251. At least a portion of the second self-locking member 131 is fixed to the second limiting member 132. The second limiting member 132 is provided with a limiting protrusion 1321, which rotates relative to the first limiting member 254 within the limiting notch 2541. By providing the limiting protrusion 1321 and the limiting notch 2541, the maximum and minimum angles of relative rotation between the supporting plate 210 and the panel 110 are limited. It is understandable that the relative rotation stroke between the limiting notch 2541 and the limiting protrusion 1321 is greater than the relative rotation stroke between the self-locking protrusion 2521 and the self-locking recess 1311. Optionally, the limiting protrusion 1321 protrudes from the second limiting member 132 along the second direction F2.

[0040] For the second limiting member 132 and the second self-locking member 131, please refer to Figure 4 The second self-locking member 131 is further bent to form a clamping portion 1312 , and the second position-limiting member 132 is further provided with a clamping hole 1322 . The clamping portion 1312 is clamped in the clamping hole 1322 , thereby achieving synchronous rotation of the second self-locking member 131 and the second position-limiting member 132 .

[0041] Further, see Figure 2 , and in combination with other drawings. The display mechanism 200 also includes a first magnetic member 260, and the first magnetic member 260 is installed on the end of the supporting plate 210 away from the panel 110. The shell 100 also includes a second magnetic member 140, and the second magnetic member 140 is installed on the panel 110 and / or the top plate 120, and the second magnetic member 140 is used to adsorb with the first magnetic member 260. Therefore, when the supporting plate 210 and the panel 110 are fitted together, the limiting notch 2541 is abutted and fixed with the limiting protrusion 1321, and the second magnetic member 140 is adsorbed and fixed with the first magnetic member 260, thereby preventing the supporting plate 210 from suddenly loosening and causing safety hazards. In addition, the first magnetic member 260 disposed on the carrier plate 210 can also be used to attract other magnetic blocks, thereby clamping thin paper such as test papers between the first magnetic member 260 and the magnetic blocks, preventing the thin paper such as the test paper from falling off the carrier plate 210; accordingly, when the paper is placed on the writing board 220, the corresponding magnetic member is arranged in the same manner as the above-mentioned scheme of the first magnetic member 260 being arranged on the carrier plate 210, and will not be repeated here. Optionally, the magnetic member includes a permanent magnet and an electromagnet, wherein the second magnetic member 140 can be a metal that can be magnetically attracted.

[0042] See also Figure 2, and in combination with other drawings. In order to make it easier for users to use the intelligent teaching aid 1000, the intelligent teaching aid 1000 in this application also includes a key assembly 500, which is installed on the top plate 120. The key assembly 500 is used to control the image displayed on the display 320. Among them, the number of key assemblies 500 can be multiple. Preferably, the number of keys can be five, which are respectively used to amplify the image captured by the camera 311, reduce the image captured by the camera 311, clear all handwriting captured by the capacitive film 230 or withdraw the previous handwriting captured by the capacitive film 230, and intercept and save the image currently displayed on the display 320.

[0043] See also Figure 2 , and in combination with other drawings. In an embodiment of the present application, the intelligent teaching aid 1000 further includes a microphone assembly 400, and the microphone assembly 400 is mounted on the panel 110 or the top plate 120 or the carrier plate 210. When the microphone assembly 400 is arranged on the panel 110, it is convenient for the user to use it when standing or sitting. When the microphone assembly 400 is arranged on the top plate 120, it is convenient for the user to use it when standing. When the microphone assembly 400 is arranged on the carrier plate 210, it is convenient for the user to use it when sitting. It is understandable that in addition to the amplification function, the microphone assembly 400 may also have a recording function, which is convenient for replaying the recording, for example: by playing back the recording of the teacher explaining the subject or question, it is convenient for students to fully understand and digest the content of the question.

[0044] See also Figure 2 and Figure 6 Based on the above structure, it is still necessary to supplement that the present application also includes a mainboard 600, and the capacitive film 230, the camera 311, the light-distributing plate 312, the display 320, the microphone assembly 400, and the key assembly 500 are electrically connected to the mainboard 600, respectively, so as to facilitate the mainboard 600 to control the above structure and process the electrical signals fed back from the above structure. Among them, the mainboard 600 is connected to the server 2000 for communication, and the server 2000 is connected to the display device 3000 for communication, so as to realize the interconnection between the devices and improve the teaching efficiency.

[0045] In summary, the intelligent teaching aid 1000 provided in this application can improve the current situation where users need to turn pages at the projector and also need to make annotations and explanations in front of the screen. Frequent walking increases the user's academic burden and reduces classroom efficiency. Among them, the intelligent teaching aid 1000 includes a shell 100, a display mechanism 200 and a projection mechanism 300. The shell 100 includes a panel 110 and a top plate 120, and the top plate 120 is installed on the panel 110. The display mechanism 200 includes a carrier plate 210, and the carrier plate 210 and the top plate 120 are arranged relative to the panel 110. The projection mechanism 300 includes a camera assembly 310 and a display 320, and the camera assembly 310 is installed on the top plate 120, wherein the camera assembly 310 is used to capture images of objects located on the carrier plate 210, and the display 320 is installed on the panel 110, and the display 320 is used to display the images captured by the camera assembly 310. With the above structure, users can place the materials to be explained on the carrier board 210. The camera assembly 310 captures images of the materials to be explained and displays them on the display 320. This allows users to perform operations such as correcting and turning pages directly on the carrier board 210. Users can also see and indicate the content of the materials to be explained on the display 320. This reduces the user's frequent movement, reduces the workload, and improves classroom efficiency.

[0046] Based on the same inventive concept, the present application further provides a teaching system 1, comprising: a server 2000, a display device 3000, and the aforementioned intelligent teaching aid 1000, wherein the display device 3000 is communicatively connected to the server 2000, and the display device 3000 comprises: a mobile terminal and a display 320, and the intelligent teaching aid 1000 is communicatively connected to the server 2000. The structure and effect of the intelligent teaching aid 1000 in the teaching system 1 are the same as those of the aforementioned intelligent teaching aid 1000, and are not described in detail here.

[0047] The intelligent teaching aid 1000 and the display device 3000 communicate and transmit data via the server 2000. The images captured by the camera 311 and the handwriting information captured by the capacitive film 230 are transmitted to the mobile terminal and the display 320. For example, the mobile terminal can be a mobile device used by a student, teacher, or parent; the display 320 can be a large screen, projector, or electronic whiteboard in the classroom.

[0048] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of this application. However, the present application can be implemented in many different forms and is not limited to the embodiments described in this specification.
