Description

Technical Field

[0001] This utility model relates to the field of information sharing device technology, specifically to an interactive teaching information sharing device. Background Technology

[0002] In today's education field, information sharing devices play a crucial role in conducting teaching activities. Among them, interactive whiteboards, as a common information sharing device, are widely used. Interactive whiteboards integrate traditional blackboards with modern information technology, enabling information interaction and sharing between teachers and students. Teachers can write, annotate, and display various teaching materials, such as documents, images, and videos, directly on the interactive whiteboard. They can also access more teaching resources through network connections, greatly enriching teaching content and methods, improving teaching efficiency, and enhancing students' learning enthusiasm.

[0003] With the continuous changes and development of teaching needs, rotatable electronic whiteboards have emerged to meet the needs of different teaching scenarios. These rotatable whiteboards can increase the flexibility of teaching to a certain extent; for example, teachers can display teaching content from different directions for better presentation. However, existing rotatable whiteboards have some problems in practical use. When the whiteboard is rotated, it often obstructs the shelf underneath. This shelf is typically used to hold teaching aids, books, and other items. When obstructed, it becomes extremely inconvenient for teachers and students to retrieve these items, seriously affecting the normal use of the shelf and reducing the convenience and smoothness of the teaching process. Utility Model Content

[0004] This invention proposes an information sharing device for interactive teaching, which solves the problem in related technologies that the rotating electronic whiteboard will block the shelf, thereby affecting the normal use of the shelf and reducing the convenience and smoothness of the teaching process.

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

[0006] An interactive teaching information sharing device includes a support frame and an electronic whiteboard. The electronic whiteboard is rotatably connected to the support frame, and a rotating structure is provided at the connection between the electronic whiteboard and the support frame. The support frame has casters at its bottom and a shelf located below the electronic whiteboard. Support rods are provided on both sides of the support frame, and the shelf is slidably connected to the support rods. A rotating shaft is provided at the connection between the electronic whiteboard and the support frame, and the rotating shaft is fixedly connected to the electronic whiteboard. When the electronic whiteboard rotates, it drives the rotating shaft to rotate. The rotating shaft is rotatably connected to the support frame, and one end of the rotating shaft opposite to the electronic whiteboard extends out onto the side of the support frame opposite to the electronic whiteboard. The rotating shaft has a linkage structure connected to the shelf. When the rotating shaft rotates, it drives the linkage structure, which in turn causes the shelf to slide on the support rods.

[0007] Furthermore, the linkage structure includes a linkage gear and a linkage rack. The linkage gear is fixedly connected to the end of the rotating shaft away from the electronic whiteboard. The linkage rack meshes with the linkage gear and is slidably connected to the support frame. The end of the linkage rack facing the shelf extends toward the shelf, and the end of the linkage rack facing the shelf is fixedly connected to the shelf.

[0008] Furthermore, the linkage rack has a "U" shaped structure, with both ends of the linkage rack on the same side extending towards the shelf and fixedly connected to the shelf. The toothed structure of the linkage rack is located inside the "U" shaped structure and on the same side inside the "U" shaped structure.

[0009] Furthermore, a protective cover is provided on the side of the support frame away from the electronic whiteboard. The protective cover is fixedly connected to the support frame. The linkage structure is located inside the protective cover. The linkage rack extends out of the protective cover at both the end facing the shelf and the end away from the shelf.

[0010] Furthermore, the top of the protective cover is provided with a fixing groove, and the end of the linkage rack away from the shelf is located on the fixing groove.

[0011] Furthermore, the support rod is provided with a limiting slide rail, and the shelves are provided with limiting sliders on both sides. The limiting sliders are located inside the limiting slide rail and are slidably connected to the limiting slide rail.

[0012] The working principle and beneficial effects of this utility model are as follows:

[0013] This invention solves this problem through the design of a rotating shaft and a linkage structure. When the interactive whiteboard rotates, it drives the rotating shaft to rotate, which in turn drives the linkage structure, which in turn causes the shelf to slide on the support rod. In this way, as the interactive whiteboard rotates, the shelf moves accordingly to avoid being blocked by the interactive whiteboard, ensuring that the shelf can be used normally in various states of the interactive whiteboard, thus improving the practicality and user experience of the interactive teaching information sharing device.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] like Figures 1-5As shown, this embodiment proposes an interactive teaching information sharing device, including a support frame 1 and an electronic whiteboard 2. The electronic whiteboard 2 is rotatably connected to the support frame 1. A rotating structure 21 is provided at the connection between the electronic whiteboard 2 and the support frame 1. A movable wheel 13 is provided at the bottom of the support frame 1. A shelf 3 is provided on the support frame 1, located below the electronic whiteboard 2. Support rods 11 are provided on both sides of the support frame 1. The shelf 3 is slidably connected to the support rods 11. A rotating shaft 4 is provided at the connection between the electronic whiteboard 2 and the support frame 1. The rotating shaft 4 is fixedly connected to the electronic whiteboard 2. When the electronic whiteboard 2 rotates, it drives the rotating shaft 4 to rotate. The rotating shaft 4 is rotatably connected to the support frame 1. One end of the rotating shaft 4 away from the electronic whiteboard 2 extends out of the support frame 1 on the side away from the electronic whiteboard 2. A linkage structure 5 is provided on the rotating shaft 4. The linkage structure 5 is connected to the shelf 3. When the rotating shaft 4 rotates, it drives the linkage structure 5, which causes the shelf 3 to slide on the support rod 11.

[0023] The support frame 1 serves as the main support for the entire device, supporting the electronic whiteboard 2, shelf 3, and other components to ensure the stability of the entire device; it also provides installation positions for the casters 13, support rods 11, etc. The electronic whiteboard 2 is the core component for interactive teaching and information sharing, displaying teaching materials, supporting writing and annotation, and facilitating teacher-student interaction. The electronic whiteboard 2 mainly consists of hardware and software. The hardware includes a display panel for presenting content, a touch system for human-computer interaction, electronic circuits for powering and processing signals for each component, and a frame and shell for protection and support. The software includes an operating system as the basic platform, teaching software specifically for instruction, and drivers that enable the hardware and software to work together. The rotating structure 21 connects the electronic whiteboard 2 and the support frame 1, allowing the horizontally placed electronic whiteboard 2 to be rotated to a vertical position (or vice versa), transforming the content originally displayed horizontally on the electronic whiteboard 2 into a vertical display. During the teaching process, this conversion can adapt to different formats of teaching materials, such as vertical images, documents, or specific teaching software interfaces. The rotating structure 21 greatly enriches the presentation format of teaching content and meets the diverse presentation needs of teaching materials. By switching between horizontal and vertical screens, teachers can more flexibly display various information, make full use of the display area of ​​the electronic whiteboard 2, improve the display effect of teaching resources, avoid affecting students' understanding of teaching content due to screen display orientation limitations, and enhance the pertinence and efficiency of teaching. The existing rotating structures 21 mainly include turntable-bearing type rotating structures, gear transmission rotating structures, and ratchet locking mechanisms. Among them, the turntable-bearing type rotating structure includes a chassis, a turntable, bearings (such as rolling bearings or sliding bearings), and a fixed bracket. The turntable is connected to the chassis through bearings, the whiteboard is fixed on the turntable, and the chassis should be fixedly connected to the support frame 1. The gear transmission rotating structure includes a driving gear (such as a bevel gear), a driven gear, a motor drive device, and a transmission shaft. The motor drives the driving gear, which transmits power to the driven gear through meshing, causing the whiteboard to rotate. The ratchet locking mechanism includes a ratchet, a limiting post, a damping device, and a base. The ratchet's one-way locking characteristic allows the whiteboard to be fixed at any angle. During rotation, the limiting post engages with the ratchet teeth, and the damping device provides rotational resistance to prevent wobbling. The casters 13 provide mobility, facilitating transport between different teaching locations. This improves the device's convenience and applicability, allowing teachers to flexibly move it to various locations within the classroom or to other classrooms as needed. The shelf 3 stores teaching aids, books, and other items, providing convenient storage space during the teaching process. The shelf 3 allows teachers and students to easily access needed items, reducing search time and improving the flow of teaching. Support rods 11 are installed on both sides of the support frame 1, providing sliding tracks for the shelf 3, allowing it to slide along the support rods 11.Meanwhile, the support rod 11 supports the electronic whiteboard 2, ensuring it remains stably positioned at a specified height. The support rod 11, in conjunction with the linkage structure 5, enables the shelf 3 to move as the electronic whiteboard 2 rotates, ensuring the shelf 3 is not obstructed by the electronic whiteboard 2. The rotating shaft 4 transmits the rotation of the electronic whiteboard 2 to the linkage structure 5. When the electronic whiteboard 2 rotates, it drives the rotating shaft 4, which in turn drives the linkage structure 5, changing the position of the shelf 3. The rotating shaft 4 should be fixedly connected to the rotation center of the rotating structure 21, such as the center of the turntable in a turntable-bearing type rotating structure, the center of the driven gear in a gear-driven rotating structure, or the center of the ratchet in a ratchet locking mechanism. The linkage structure 5 connects the rotating shaft 4 and the shelf 3. When the rotating shaft 4 rotates, it drives the linkage structure 5, causing the shelf 3 to slide on the support rod 11, thus achieving linkage between the rotation of the electronic whiteboard 2 and the movement of the shelf 3. Through ingenious linkage design, the problem of the shelf 3 being blocked by the electronic whiteboard 2 is solved, ensuring the normal use of the shelf 3 during the rotation of the electronic whiteboard 2.

[0024] In this embodiment, the linkage structure 5 includes a linkage gear 51 and a linkage rack 52. The linkage gear 51 is fixedly connected to the end of the rotating shaft 4 away from the electronic whiteboard 2. The linkage rack 52 meshes with the linkage gear 51 and is slidably connected to the support frame 1. The end of the linkage rack 52 facing the shelf 3 extends towards the shelf 3 and is fixedly connected to the shelf 3. The linkage rack 52 has a "U"-shaped structure. Both ends of the linkage rack 52 on the same side extend towards the shelf 3 and are fixedly connected to the shelf 3. The toothed structure of the linkage rack 52 is located inside the "U"-shaped structure and on the same side inside the "U"-shaped structure. The support rod 11 is provided with a limiting slide rail 12, and limiting sliders 31 are provided on both sides of the shelf 3. The limiting sliders 31 are located inside the limiting slide rail 12 and are slidably connected to the limiting slide rail 12.

[0025] The linkage gear 51 is fixedly connected to the end of the rotating shaft 4 opposite to the electronic whiteboard 2. When the rotating shaft 4 rotates with the electronic whiteboard 2, the linkage gear 51 rotates synchronously. Because it meshes with the linkage rack 52, it can transmit the rotational motion of the rotating shaft 4 to the linkage rack 52, thereby driving the linkage rack 52 to perform linear motion. As the transmission component between the rotating shaft 4 and the linkage rack 52, the linkage gear 51 cleverly achieves the conversion of motion forms, transforming the rotational motion generated by the electronic whiteboard 2 into the linear motion of the linkage rack 52, providing power support for the subsequent movement of the shelf 3, and ensuring the smooth operation of the entire device's linkage mechanism. The linkage rack 52 meshes with the linkage gear 51 and performs linear motion under the drive of the linkage gear 51. It has a "U"-shaped structure, with both ends on the same side extending towards the shelf 3 and fixedly connected to it. Therefore, when the linkage rack 52 moves, it can drive the shelf 3 to slide along the support rod 11. Meanwhile, its toothed structure is located inside the "U"-shaped structure and on the same side. This structural design ensures stable meshing with the linkage gear 51, ensuring the reliability of transmission. The linkage rack 52, through its cooperation with the linkage gear 51, realizes the movement of the shelf 3, effectively solving the problem of the electronic whiteboard 2 obstructing the shelf 3 when rotating. The "U"-shaped structure and specific toothed position design not only enhance the stability of the connection with the shelf 3, but also ensure the stability of the transmission with the linkage gear 51, improving the reliability and durability of the entire device. The limiting slide rail 12 is used to provide a specific movement trajectory for the limiting slider 31, so that the shelf 3 can only slide along the direction set by the support rod 11, which restricts and guides the movement of the shelf 3, ensuring its accuracy and stability, and preventing the shelf 3 from shaking, deviating, or detaching from the support rod 11 during the sliding process. The limiting slider 31 is used to cooperate with the limiting slide rail 12, and slides within the limiting slide rail 12 as the shelf 3 moves. It connects the shelf 3 to the limiting slide rail 12, so that the shelf 3 can slide smoothly under the constraint of the limiting slide rail 12, and can also bear the weight of the shelf 3 and various forces generated during the movement.

[0026] In this embodiment, a protective cover 53 is provided on the side of the support frame 1 facing away from the electronic whiteboard 2. The protective cover 53 is fixedly connected to the support frame 1. The linkage structure 5 is located inside the protective cover 53. The linkage rack 52 extends out of the protective cover 53 at both the end facing the shelf 3 and the end facing away from the shelf 3. A fixing groove 54 is provided on the top of the protective cover 53, and the end of the linkage rack 52 facing away from the shelf 3 is located on the fixing groove 54.

[0027] The protective cover 53 protects the linkage structure 5 from collisions and scratches caused by external objects during daily use, and prevents dust and debris from entering the linkage structure 5 and affecting the normal meshing and transmission of the linkage gear 51 and linkage rack 52. The protective cover 53 effectively extends the service life of the linkage structure 5, ensures its stable operation, and thus ensures the continuous and reliable operation of the linkage mechanism between the rotation of the electronic whiteboard 2 and the movement of the shelf 3 in the entire device. This reduces device malfunctions caused by damage to the linkage structure 5 and improves the stability and reliability of the interactive teaching information sharing device. The protective cover 53 extends from both the end of the linkage rack 52 facing the shelf 3 and the end facing away from the shelf 3. The end facing the shelf 3 extends and is fixedly connected to the shelf 3, effectively driving the shelf 3. A fixing groove 54 is provided on the top of the protective cover 53 to accommodate the end of the linkage rack 52 facing away from the shelf 3. A fixed support point is provided for the linkage rack 52, which restricts the displacement of the linkage rack 52 in the vertical direction, so that the linkage rack 52 maintains a stable position during the movement, prevents it from shaking during the movement, and ensures that the linkage rack 52 and the linkage gear 51 always maintain a good meshing state.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
