[0001] This utility model relates to the field of electronic device technology, and in particular to an educational tablet computer with a finger-reading function. Background Technology

[0002] In modern education, educational tablets are widely used in classroom teaching and self-directed learning as a convenient and efficient teaching aid. To enhance the learning experience, especially for learning scenarios such as reading, translation, and literacy, many educational tablets are equipped with a reading mirror. The reading mirror magnifies the text, helping students observe text details more clearly. This is of great significance for young children learning to read, people with poor eyesight reading, and those learning foreign languages ​​to see word details.

[0003] However, most existing educational tablets and reading mirrors use magnetic attachment, which has several problems. Magnetic connections rely on magnetic force to hold the reading mirror and tablet together, resulting in poor stability. When the tablet is placed on a table or similar surface, if the table shakes or the user accidentally bumps the reading mirror, it can easily detach from the tablet or shift position. In such cases, the user needs to frequently adjust the reading mirror's position to ensure it functions properly, increasing the user's workload and affecting the continuity and effectiveness of learning. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, this utility model provides an educational tablet computer with a finger-reading function.

[0005] The technical solution of this utility model is implemented as follows:

[0006] An educational tablet computer with a finger-reading function includes a finger-reading mirror structure that can be detachably installed on the tablet computer. The finger-reading mirror structure includes a clamping part for clamping on the tablet computer and having a plane mirror, a clamping plate movably disposed on the clamping part, and an adjustment mechanism for adjusting the degree of fit between the clamping plate and the tablet computer. The clamping part has a clamping groove for engaging with one side of the tablet computer and accommodating the clamping plate, and the clamping plate is movably disposed in the clamping groove.

[0007] Furthermore, a receiving groove is provided in the clamping groove, extending to the side of the clamping part away from the plane mirror, and an extension plate extending through the receiving groove is provided on the side of the clamping plate near the receiving groove, and the extension plate is rotatably connected in the receiving groove.

[0008] Furthermore, the adjustment mechanism includes a knob rotatably disposed on the side of the clamping part away from the plane mirror, a moving block screwed inside the knob, and a pressing block protruding on the side of the moving block near the extension plate, the bottom surface of the pressing block being an inclined surface.

[0009] Furthermore, the extension plate has a slot for accommodating the extrusion block, the bottom of the slot is an inclined surface, and the bottom of the slot is in contact with the bottom surface of the extrusion block.

[0010] Furthermore, the top and bottom of the extension plate are reserved with a certain space corresponding to the inner wall of the receiving groove, and the two sides of the extension plate are rotatably connected to the receiving groove through a rotating shaft.

[0011] Furthermore, the knob has a threaded groove for accommodating the movable block, and the movable block is screwed into the threaded groove through the thread on its outer wall.

[0012] Furthermore, the two sides of the extrusion block are flat cut surfaces, and its two sides fit into the inner walls of the two sides of the slot.

[0013] Furthermore, the clamping part is provided with a receiving groove for accommodating the plane mirror. The plane mirror is tilted at a certain angle relative to the tablet computer, and the plane mirror reflects the content displayed on the tablet computer screen to the camera set on the tablet computer.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This invention incorporates a movable clamp within the reading mirror structure to adhere to a tablet computer. An adjustment mechanism regulates the adhesion between the clamp and the tablet, thus adjusting the stability of the reading mirror structure. This effectively prevents the reading mirror from detaching from the tablet, replacing the existing method of magnetically attaching the reading mirror to the tablet. This improves installation stability and prevents the reading mirror from easily detaching or shifting position. It also solves the problem of poor stability in existing magnetic connections between educational tablets and reading mirrors, where magnetic force adheres to the reading mirror and tablet. Even if the user accidentally touches the reading mirror during operation, it will not easily detach from the tablet or shift position, ensuring uninterrupted learning. Attached Figure Description

[0022] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0023] like Figure 1-5 As shown, this embodiment provides an educational tablet computer with a finger-reading function, including a finger-reading mirror structure 2 that can be detachably installed on the tablet computer 1. The finger-reading mirror structure 2 includes a clamping part 3 for clamping on the tablet computer 1 and having a plane mirror 18, a clamping plate 4 movably disposed on the clamping part 3, and an adjustment mechanism 5 for adjusting the degree of contact between the clamping plate 4 and the tablet computer 1. The clamping part 3 has a clamping groove 6 for engaging with one side of the tablet computer 1 and accommodating the clamping plate 4, and the clamping plate 4 is movably disposed in the clamping groove 6.

[0024] In this embodiment, the finger-reading mirror structure 2 is used to assist the user in performing finger-reading operations on the tablet computer 1. It realizes the finger-reading function by reflecting the screen content to the camera 14. The clamping part 3 is the main part of the finger-reading mirror structure 2 and is used to fix the entire finger-reading mirror structure 2. The clamping groove 6 is opened on one side of the clamping part 3, and one side edge of the tablet computer 1 is engaged into the clamping groove 6. The clamping plate 4 set in the clamping groove 6 is used to clamp the tablet computer 1. The tightness of the clamping plate 4 is adjusted by the adjusting mechanism 5, so that the clamping part can be firmly clamped on the tablet computer 1, thereby realizing the stable connection between the finger-reading mirror structure 2 and the tablet computer 1.

[0025] Furthermore, the clamping groove 6 has a receiving groove 7 that extends through to the side of the clamping part 3 away from the plane mirror 18, and the clamping plate 4 has an extension plate 8 extending through the receiving groove 7 on the side close to the receiving groove 7, and the extension plate 8 is rotatably connected in the receiving groove 7.

[0026] Specifically, the clamping plate 4 is disposed between the inner wall of the clamping groove 6 and the outer wall of the tablet computer 1. When the clamping plate 4 is driven by the adjusting mechanism 5 to press against the outer wall of the tablet computer 1, it can improve the stability of the finger reading mirror structure 2 installed on the tablet computer 1. The receiving groove 7 is a groove that communicates with the clamping groove 6 and is used to install and receive the extension plate 8 of the clamping plate 4, providing the moving space for the extension plate 8.

[0027] Furthermore, the adjustment mechanism 5 includes a knob 9 rotatably disposed on the side of the clamping part 3 away from the plane mirror 18, and a moving block 10 screwed inside the knob 9. The moving block 10 has a pressing block 11 protruding on the side near the extension plate 8, and the bottom surface of the pressing block is an inclined surface.

[0028] Furthermore, the extension plate 8 has a slot 15 for accommodating the extrusion block 11. The bottom of the slot 15 is an inclined surface, and the bottom of the slot 15 is in contact with the bottom surface of the extrusion block.

[0029] In this embodiment, by rotating the knob 9, the threaded groove 12 inside the knob 9 interacts with the external thread of the moving block 10, pushing the moving block 10 to move along the threaded groove 12. The movement of the moving block 10 drives the pressing block 11 to move towards the extension plate 8. Through the movement of the moving block 10, the pressing block 11 applies pressure to the extension plate 8. After being pressed, the extension plate 8 rotates with the connection between the receiving groove 7 and the extension plate 8 as the fulcrum. The clamping plate 4 on the other side of the extension plate 8 is raised, which increases the adhesion between the clamping plate 4 and the tablet computer 1, thereby ensuring the stable installation of the finger reading mirror structure 2.

[0030] By rotating the knob 9, users can flexibly adjust the fit between the clamping plate 4 and the tablet computer 1 to accommodate tablet computers 1 of different thicknesses. The design of the pressing block 11 utilizes the principle of inclined plane, which can effectively apply pressure to the extension plate 8 to ensure a tight fit between the clamping plate 4 and the tablet computer 1, thereby improving the stability of the installation. The design of the knob 9 allows users to easily perform adjustment operations, improving the convenience of use.

[0031] In this embodiment, the clamping part 3 is provided with a mounting ring 16 for mounting the knob 9, and a limiting ring 17 is provided at the connection part between the knob 9 and the mounting ring 16, which engages with the inner wall of the mounting ring 16, so that the knob 9 can be rotated and mounted on the clamping part 3.

[0032] Furthermore, the top and bottom of the extension plate 8 are reserved with a certain space corresponding to the inner wall of the receiving groove 7, and the two sides of the extension plate 8 are rotatably connected to the receiving groove 7 through a rotating shaft.

[0033] Furthermore, the knob 9 has a threaded groove 12 for accommodating the movable block 10, and the movable block 10 is screwed into the threaded groove 12 through the thread on its outer wall.

[0034] The top and bottom of the extension plate 8 are reserved with a certain space from the corresponding inner wall of the receiving groove 7, so that the extension plate 8 can rotate freely within a certain range without obstruction; the two sides of the extension plate 8 are connected to the rotating shaft in the receiving groove 7 through the rotating shaft, so that it can rotate flexibly.

[0035] Furthermore, the two sides of the extrusion block 11 are flat cut surfaces, and its two sides are in contact with the inner walls of the two sides of the slot 15.

[0036] The two sides of the extrusion block 11 are designed with flat cut surfaces, which fit against the inner walls of the slots 15 on both sides of the extension plate 8, ensuring that the extrusion block 11 can stably cooperate with the slots 15 during the adjustment process, and effectively preventing the extrusion block 11 from rotating and shifting along with the moving block 10 during the adjustment process.

[0037] Furthermore, the clamping part 3 is provided with a receiving groove 13 for accommodating the plane mirror 18. The plane mirror 18 is tilted at a certain angle relative to the tablet computer 1, and the plane mirror 18 reflects the content displayed on the screen of the tablet computer 1 to the camera 14 set on the tablet computer 1.

[0038] In this embodiment, the camera 14 captures the text image on the screen by reflecting the content through the reading mirror structure 2, and uses the OCR (Optical Character Recognition) technology on the tablet computer 1 to convert the text in the image into an editable text format. The user can point to the text on the screen through the reading mirror, and the OCR technology will recognize and extract the text content in real time, providing basic data for subsequent voice reading and intelligent processing.

[0039] By using TTS (Text-to-Speech) technology, the text content recognized by OCR is converted into speech output, realizing the voice reading function of finger reading. Users point to the text on the screen with a finger reading mirror, and after OCR technology recognizes the text, TTS technology converts the text content into speech, helping users to better understand and learn the content.

[0040] The tablet PC 1 uses deep learning algorithms to correct OCR recognition results, improving the accuracy of text recognition, especially in complex backgrounds or blurry images; deep learning algorithms can also optimize TTS speech synthesis, making speech output more natural and fluent, and improving user experience.

[0041] The working process and principle of this utility model are as follows:

[0042] When using this educational tablet computer, the user first installs the finger-reading mirror structure 2 on one side of the tablet computer 1 through the clamping groove 6 of the clamping part 3. An extension plate 8 is provided inside the clamping groove 6, and its two sides are connected to the rotating shaft in the receiving groove 7 via rotating shafts, ensuring that the extension plate 8 can rotate flexibly. The user rotates the knob 9, and the threaded groove 12 inside the knob 9 interacts with the external thread of the moving block 10, pushing the moving block 10 to move along the threaded groove 12. The movement of the moving block 10 causes the pressing block 11 to move towards the extension plate 8. The inclined surface of the pressing block 11 fits against the bottom of the slot 15 on the extension plate 8, applying pressure to the extension plate 8. After being pressed, the extension plate 8 rotates around the connection point between the receiving groove 7 and the extension plate 8, making the clamping plate 4 fit tightly against the outer wall of the tablet computer 1, ensuring that the finger-reading mirror structure 2 is securely installed on the tablet computer 1.

[0043] The plane mirror 18 is tilted at a certain angle relative to the tablet computer 1, reflecting the screen content to the camera 14. The camera 14 captures the reflected text image, providing a basis for the subsequent finger reading function.

[0044] During use, the OCR technology in Tablet 1 converts the text in the image into an editable text format, and the TTS technology converts the text content recognized by OCR into speech output, realizing the voice reading function, which helps users better understand and learn the content. At the same time, the deep learning algorithm corrects the OCR recognition results, improves the accuracy of text recognition, and optimizes the speech synthesis of TTS, making the speech output more natural and fluent, and improving the user experience.

[0045] This utility model is based on the adjustment of mechanical structure and optical reflection. The clamping part 3 serves as the main body of the finger-reading mirror structure 2. Through the design of the clamping groove 6 and the clamping plate 4, a stable connection with the tablet computer 1 is achieved. The receiving groove 7 opened in the clamping groove 6 is used to install and receive the extension plate 8. A certain space is reserved between the top and bottom of the extension plate 8 and the inner wall of the receiving groove 7 to ensure that it can rotate freely. The knob 9, the moving block 10 and the pressing block 11 in the adjustment mechanism 5 work together. By rotating the knob 9, the moving block 10 moves along the threaded groove 12, driving the pressing block 11 to apply pressure to the extension plate 8. The flat cut surfaces on both sides fit snugly against the inner walls of the slots 15 on the extension plate 8, ensuring that the squeezing block 11 can stably cooperate with the slots 15 during adjustment, effectively preventing the squeezing block 11 from rotating or shifting during adjustment. The plane mirror 18 is installed in the receiving slot 13 of the clamping part 3, at a certain angle relative to the tablet computer 1, reflecting the screen content to the camera 14, ensuring that the reflected content can be accurately captured by the camera 14. This not only ensures the stable installation of the finger reading mirror structure 2, but also adapts to tablet computers 1 of different thicknesses through a flexible adjustment mechanism, improving the product's versatility and ease of use.
