Technical Field
[0001] This utility model relates to the field of teaching equipment technology, specifically to a combined electronic blackboard. Background Technology
[0002] With the development of technology, electronic teaching equipment has been widely used in the education field. Traditional single-function blackboards can no longer meet diverse teaching needs, leading to the emergence of modular electronic blackboards. Currently, modular electronic blackboards on the market generally embed an electronic screen at the back of the blackboard, which is revealed by sliding the blackboard, thus forming a modular electronic blackboard. This achieves a certain degree of integration between electronic teaching and traditional blackboard teaching, providing more options for teaching.
[0003] Existing modular electronic blackboards require folding to reduce their area to half, impacting the normal writing space. Furthermore, the electronic screen in the middle divides the two sides of the blackboard, creating gaps in the writing and hindering the full utilization of space, thus affecting teaching effectiveness. Utility Model Content
[0004] The technical problem this invention aims to solve is that existing modular electronic blackboards require folding during use, which reduces the blackboard area to half its original size, affecting the normal writing area, failing to fully utilize space, and impacting teaching effectiveness.
[0005] To solve the above-mentioned technical problems, the present invention provides a combined electronic blackboard, including a structural frame and an electronic screen. The internal part of the structural frame is divided into two identical mounting frames. The electronic screen is located inside one of the mounting frames. A first blackboard body and a second blackboard body are provided on the side of the structural frame facing the electronic screen, wherein the second blackboard body is fixedly connected to the structural frame.
[0006] A movable frame is slidably connected to the outer side of the first blackboard body, and the movable frame is U-shaped. Guide wheels are provided on both sides of the top of the movable frame, and a corresponding guide rail is provided at the top of the structural frame at the guide wheels. A protective cover is provided above the guide rail.
[0007] As a preferred embodiment of this utility model, the second blackboard body is 1 / 2 of the internal area of the structural frame.
[0008] As a preferred technical solution of this utility model, the outer surface of the movable frame is the same shape as the second blackboard body, and the U-shaped structure of the movable frame is horizontally arranged, with the opening of the U-shaped structure located on the side close to the second blackboard body.
[0009] As a preferred technical solution of this utility model, the upper and lower ends of the first blackboard body are provided with rectangular guide blocks, and the outer side of the guide blocks is provided with rollers. The inner side of the movable frame is provided with a movable groove that matches the shape of the guide blocks and rollers.
[0010] As a preferred embodiment of this utility model, both the movable frame and the first blackboard body are provided with embedded grooves on the side away from the second blackboard body.
[0011] As a preferred embodiment of this utility model, the bottom of the guide wheel is rotatably connected by a guide rod, and the bottom of the guide rail matches the shape of the guide rod, while the top of the guide rail matches the shape of the guide wheel.
[0012] As a preferred technical solution of this utility model, the internal direction of the guide slide rail is parallel to the structural frame, and the guide slide rail is an extended track inclined at 45 degrees at the guide wheel. At the same time, the vertical distance between the extended track and the guide slide rail is the same as the thickness of the moving frame.
[0013] The advantages of this utility model compared with the prior art are as follows:
[0014] The first blackboard body in this modular electronic blackboard can move flexibly on the structural frame through the cooperation of the moving frame, guide wheels and guide rails, making it easy to switch between using the electronic screen and the blackboard. It also forms a whole blackboard with the second blackboard body. The area of the blackboard is not reduced when using the electronic screen, so the space can be fully utilized.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] Example 1:
[0024] As per the instruction manual Figure 1-4 As shown, a combined electronic blackboard includes a structural frame 1 and an electronic screen 2. The interior of the structural frame 1 is divided into two identical mounting frames 3. The electronic screen 2 is located inside one mounting frame 3. A first blackboard body 4 and a second blackboard body 5 are provided on the side of the structural frame 1 facing the electronic screen 2. The second blackboard body 5 is fixedly connected to the structural frame 1 and is half the internal area of the structural frame 1.
[0025] In this utility model, a movable frame 6 is slidably connected to the outer side of the first blackboard body 4, and the movable frame 6 has an overall U-shaped structure. The outer shape of the movable frame 6 is the same as that of the second blackboard body 5, and the U-shaped structure of the movable frame 6 is horizontally arranged. The opening of the U-shaped structure is located on the side close to the second blackboard body 5. Both the movable frame 6 and the first blackboard body 4 are provided with embedded grooves 11 on the side away from the second blackboard body 5.
[0026] In this utility model, guide wheels 7 are provided on both sides of the top of the movable frame 6, and a corresponding guide rail 8 is provided at the top of the structural frame 1 at the guide wheel 7. The bottom of the guide wheel 7 is rotatably connected by the guide rod 12, and the bottom of the guide rail 8 matches the shape of the guide rod 12. The top of the guide rail 8 matches the shape of the guide wheel 7. The internal direction of the guide rail 8 is parallel to the structural frame 1, and the guide rail 8 at the guide wheel 7 is an extended track inclined at 45 degrees. At the same time, the vertical distance between the extended track and the guide rail 8 is the same as the thickness of the movable frame 6. A protective cover 9 is provided on the top of the guide rail 8.
[0027] In this utility model, the upper and lower ends of the first blackboard body 4 are provided with rectangular guide blocks, and the outer side of the guide blocks is provided with rollers. The inner side of the movable frame 6 is provided with a movable groove 10 that matches the shape of the guide blocks and rollers.
[0028] In practical implementation, when the electronic screen 2 is needed, the movable frame 6 is pulled outward, and the guide wheel 7 rolls within the guide rail 8. Due to the special design of the guide rail 8, it is an extended track at a 45-degree angle at the guide wheel 7, and the vertical distance between the extended track and the guide rail 8 is the same as the thickness of the movable frame 6. This allows the first blackboard body 4 to move smoothly to the front of the second blackboard and switch positions. The guide blocks and rollers at the upper and lower ends of the first blackboard body 4 roll within the movable groove 10 of the movable frame 6, ensuring smooth sliding of the first blackboard body 4 within the movable frame 6. After moving to the front of the second blackboard, the movable frame 6 is positioned, and the first blackboard body 4 is pulled further to unfold it, forming an integrated blackboard structure with the second blackboard body 5. At the same time, the protective cover 9 protects the guide rail 8, preventing debris from affecting the normal operation of the guide wheel 7.
