By setting up the protective mechanism 2, when the control panel 11 is idle... When in operation, the protective plate 201 can cover the control panel 11, preventing accidental contact caused by teachers and students moving around or operating carelessly during the teaching process. This prevents problems such as equipment malfunction, program interruption, or interface switching, ensuring the smoothness of classroom teaching. At the same time, the protective plate 201 can also block falling chalk dust, reducing contamination of the screen, buttons, and interfaces. When the protective plate 201 is open or closed, it can serve as an extension platform for the multimedia lectern body 1. Teachers can place teaching materials such as Chinese textbooks, lesson plans, and notebooks on the surface of the protective plate 201, alleviating the problem of insufficient space in the multimedia lectern body 1.

[0027] The support mechanism 3 includes a fixing block 301, which is fixedly connected to the bottom of the protective plate 201. There are two fixing blocks 301. A first connecting rod 302 is rotatably connected between the opposite sides of the two fixing blocks 301. Two support rods 303 are fixedly connected to the surface of the first connecting rod 302. A second connecting rod 304 is fixedly connected to one end of the two support rods 303. Two positioning blocks 305 are fixedly connected to one side of the multimedia lectern body 1. The top of each positioning block 305 is provided with a positioning groove 306. The positioning groove 306 works in conjunction with the second connecting rod 304. By setting up the support mechanism 3, the protective plate 201 in the open state can be supported when the multimedia control panel 11 is used, so as to prevent the protective plate 201 from being suspended. The support rods 303 can provide support force to the protective plate 201. When the protective plate 201 is supported and stabilized, it can become an additional working platform.

[0028] Reference Figure 4A damping bearing 9 is fixedly connected to the inner wall of the multimedia lectern body 1. The inner wall of the inner ring of the damping bearing 9 is fixedly connected to one end of the rotating shaft 207. The rotating shaft 207 is rotatably connected to the inner wall of the multimedia lectern body 1 through the damping bearing 9. By setting the damping bearing 9, the rotation of the rotating shaft 207 will be subject to appropriate resistance control, making the operation process smoother and more controllable, and also preventing the protective plate 201 from suddenly moving due to inertia or other external forces.

[0029] Reference Figure 2 The bottom of the protective plate 201 is fixedly connected to a support foot 4. The bottom of the support foot 4 contacts the top of the multimedia lectern body 1. By setting the support foot 4, the protective plate 201 can be supported after it is closed, so as to prevent the protective plate 201 from being suspended and increase the load-bearing capacity of the protective plate 201.

[0030] Reference Figure 2 and Figure 3 The top of the multimedia lectern body 1 is fixedly connected to the mounting box 5. The rotating rod 205 is rotatably connected to the inner wall of the mounting box 5. One end of the rotating rod 205 extends through to the outside of the mounting box 5. A handle 7 is fixedly connected to one end of the rotating rod 205. By setting the mounting box 5, the limit block 204 can be protected and supported to avoid accidental contact with the limit block 204. The handle 7 allows the user to easily rotate the limit block 204, thereby making it easy to release the lock on the card block 202.

[0031] Reference Figure 3 A torsion spring 6 is sleeved on the surface of the rotating rod 205. One end of the torsion spring 6 is fixedly connected to the surface of the rotating rod 205, and the other end of the torsion spring 6 is fixedly connected to the inner wall of the mounting box 5. By setting the torsion spring 6, torsion force can be provided to the rotating rod 205 and the limiting block 204, ensuring that the rotating rod 205 and the limiting block 204 can return to their original position after rotation. At the same time, the locking block 202 can be locked to ensure the stability of the protective plate 201 after it is closed.

[0032] Reference Figure 4 Both ends of the second connecting rod 304 are fixedly connected to mounting blocks 8. One side of each mounting block 8 contacts one side of each positioning block 305. By setting the mounting blocks 8, the second connecting rod 304 can be limited to prevent it from accidentally detaching from the positioning groove 306, thus ensuring the safety of the support.

[0033] Reference Figure 4 An elastic ring 10 is fixedly connected to the bottom of the protective plate 201. The inner wall of the elastic ring 10 is in contact with the surface of the second connecting rod 304. By setting the elastic ring 10, the elasticity of the elastic ring 10 can be used to lock the retracted support rod 303 and the second connecting rod 304, ensuring that the protective plate 201 closes smoothly.

[0034] Working Principle: The multimedia lectern body 1 is an integrated platform that integrates various hardware devices such as a computer, projector, sound system, and microphone. These devices are interconnected with the monitor through a series of interfaces, and the teaching content is displayed on the monitor. The control panel 11 is the core control part of the multimedia lectern, helping teachers easily manage and switch different teaching content. This is existing technology and will not be elaborated further. When the protective plate 201 is closed, when the user needs to use the control panel 11, the user can rotate the handle 7 to rotate the rotating rod 205 and the limit block 204. At this time, the torsion spring 6 will twist, providing torsional potential energy to the rotating rod 205 and the limit block 204, facilitating the rotation of the rod 205 and the limit block 204. Block 204 returns to its original position. By rotating the rotating rod 205 and the limiting block 204, the limiting block 204 disengages from the slot 203 within the locking block 202, thereby releasing the locking block 204 from the locking block 202. At this point, the user rotates the protective plate 201, causing the locking block 202 to disengage from the limiting slot 206. The user then releases the handle 7, at which point the torsion spring 6 rebounds, causing the rotating rod 205 and the limiting block 204 to return to their original positions. The protective plate 201 rotates around the rotating shaft 207. When the rotating shaft 207 rotates, it drives the inner ring of the damping bearing 9 to rotate. The outer ring of the damping bearing 9 is fixed inside the multimedia lectern body 1. The damping bearing 9 makes the rotation process smoother and more controllable, and also prevents rotation due to inertia or other external forces. If the protective plate 201 suddenly moves, the user can fully open the protective plate 201 and then manually pull the second connecting rod, which is fixed to the bottom of the protective plate 201 by the elastic ring 10, out of the elastic ring 10. The elastic ring 10 serves to limit and fix the movement. When it needs to be unfolded, the second connecting rod 304 can be pulled open by its own elasticity. As the second connecting rod unfolds, it will drive the two connected support rods 303 to unfold synchronously. The support rods 303 rotate around the first connecting rod 302. The two fixing blocks 301 can limit the first connecting rod 302 to ensure the stability of the rotation. After the support rods 303 are unfolded, the user places the second connecting rod in the positioning grooves 306 of the two positioning blocks 305 on one side of the multimedia lectern body 1. The positioning block 305 and the 06 can mechanically limit and support the second connecting rod, ensuring that the protective plate 201 remains stable when carrying Chinese teaching materials, and will not shift or collapse. This ensures the safety of the protective plate 201 in the open state. When the control panel 11 is idle, the user can retract the support rod 303 and the second connecting rod 304, fix the second connecting rod 304 through the elastic ring 10, and then rotate the protective plate 201. When the protective plate 201 is closed, the thrust of rotating the protective plate 201 pushes the locking block 202 into the limiting groove 206 of the multimedia lectern body 1. At this time, the locking block 202 will push the limiting block 204 open, and the limiting block 204 will rotate around the rotating rod 205. At this time, the torsion spring 6 is torsionally stored.As the locking block 202 is pushed in, the limiting block 204 contacts the slot 203 on the surface of the locking block 202. The slot 203 provides rotation space for the limiting block 204. When the limiting block 204 enters the slot 203, the torsion spring 6 rebounds, thereby locking the limiting block 204 and locking the locking block 202, ensuring the safety of the closed protective plate 201. The supporting feet 4 support the closed protective plate 201, ensuring its load-bearing capacity. Whether open or closed, the protective plate 201 serves as an extension platform for the multimedia lectern body 1. Teachers can place teaching materials such as textbooks, lesson plans, and notebooks on the surface of the protective plate 201, alleviating the problem of insufficient usable space in the multimedia lectern body 1.
