Description

Technical Field

[0001] This invention relates to the field of teaching equipment technology, specifically to a display device for cultural comparison teaching. Background Technology

[0002] Comparative cultural teaching is a teaching method centered on comparing different cultures. It aims to help learners understand cultural diversity and enhance their intercultural awareness and communication skills by systematically comparing the similarities and differences between two or more cultures. In current intercultural or comparative cultural teaching, teachers typically need to simultaneously display physical teaching aids (such as traditional handicrafts and objects) from different cultural backgrounds, along with corresponding written explanations, illustrations, or blackboard content. This helps learners understand the similarities and differences between different cultures, thereby enhancing their intercultural awareness and communication skills, and helping students intuitively understand cultural differences and commonalities.

[0003] However, existing teaching and display devices often rely on podium displays or handheld items for demonstration, making it impossible to observe small cultural items from all angles. Students find it difficult to fully understand their structure, patterns, or craftsmanship details. Furthermore, existing teaching equipment often separates physical displays from textual explanations, failing to achieve simultaneous presentation. Summary of the Invention

[0030] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0031] Please see Figure 1-10This embodiment provides a display device for cultural comparison teaching, comprising: a cabinet 1, with a mounting block 2 fixedly installed on the top of the cabinet 1, two mounting cavities 201 formed on the top of the mounting block 2, and a storage cavity 103 on one side of the cabinet 1; and a display component disposed inside the storage cavity 103, comprising: multiple electric push rods 603 disposed inside the cabinet 1, each of the multiple electric push rods 603 having an equipment box 6 fixedly connected to its top, each of the multiple equipment boxes 6 having a motor 601 fixedly installed inside, each of the motors 601 having a turntable 602 driven to its top via a rotating shaft, a servo motor b5 fixedly installed inside the cabinet 1, a slider 502 disposed inside the storage cavity 103, a camera b504 fixedly installed on one side of the slider 502, and a fixed mounting block 2 on one side. The cabinet is equipped with a display screen b701; an expansion component is installed inside the cabinet 1, which includes: storage cavities a102 on both sides of the cabinet 1, each of the two storage cavities a102 having a mounting plate 301 inside, and an expansion blackboard 302 installed on one side of each of the two mounting plates 301; and a camera component is installed between the cabinet 1 and the mounting block 2, which includes: servo motors a202 fixedly installed inside each of the two mounting cavities 201, a moving platform 204 fixedly installed inside each of the two mounting cavities 201, an electric telescopic rod 205 fixedly installed on the top of the moving platform 204, a mounting plate 206 fixedly connected to the bottom of the electric telescopic rod 205, a camera a207 fixedly installed on one side of the mounting plate 206, and two display screens a7 fixedly installed on one side of the mounting block 2.

[0032] Among them, by setting up the display components, it is possible to raise, lower, rotate and switch between multiple cultural comparison items for shooting, which makes it easier for students to observe different cultural objects and enhances the intuitiveness of teaching and the depth of cultural cognition. Secondly, by setting up the expansion components, the hidden expansion blackboard 302 can be quickly unfolded, providing an additional writing area to support the juxtaposition of bicultural content, enhancing classroom comparative analysis capabilities and space utilization efficiency. At the same time, the setting of the spring limit block 401, magnet 402 and magnet strip 304 facilitates the limiting of the mounting plate 301. Next, by setting up the shooting component, the written content on the extended blackboard 302 can be dynamically captured and projected onto the corresponding display screen in real time, solving the problem of students at the side and rear of the classroom having difficulty viewing. At the same time, it works in conjunction with the display component to achieve synchronous display of text and physical objects.

[0033] Among them, the servo motor b5 is connected to the screw 501 via a rotating shaft on one side, the slider 502 has a threaded hole that mates with the screw 501 on one side, the blackboard 702 is fixedly installed on one side of the cabinet 1, the storage cavity 101 is opened on one side of the cabinet 1, and two open storage cabinets 8 are fixedly installed on one side of the cabinet 1; multiple equipment boxes 6 are located inside the storage cavity 103, one end of the screw 501 passes through the threaded hole on the slider 502 and is connected to one side of the inner wall of the storage cavity 103 via a bearing, and an LED light 503 is fixedly installed on the top of the inner wall of the storage cavity 103.

[0034] In use, open the protective door on one side of the storage compartment 103, then take out the smaller items to be displayed. Attach a piece of double-sided tape to the top of each of the multiple turntables 602, then press the items onto the tape one by one. Next, control the electric push rod 603 to extend, causing the equipment box 6 and the turntables 602 to rise and move to the side of the camera b504, capturing images of the items on the turntables 602. The images are then transmitted in real-time to the display screen b701 via the camera 504. Simultaneously, activating the motor 601 rotates the turntables 602 and the items, allowing the camera b504 to focus on them. The object is photographed from 360 degrees to allow students to observe it in more detail. After observing the first object, the first electric push rod 603 is retracted and the second electric push rod 603 is raised. Then, the servo motor b5 is activated, which rotates the screw 501, causing the slider 502 to move the camera b504 along the direction of the screw 501, bringing the camera b504 closer to the second object for photographing. In addition, the LED light 503 provides a light source for the camera b504.

[0035] Each of the two servo motors a202 has a lead screw 203 connected to one side via a rotating shaft. The mounting block 2 has two storage cavities b208 inside. L-shaped sliders 4 are provided on the outer sides of both lead screws 203. Each of the two L-shaped sliders 4 and the two moving platforms 204 has a screw hole on one side that mates with the lead screw 203. One side of the lead screw 203 passes through the screw hole on the L-shaped slider 4 and the moving platform 204, and is connected to one side of the inner wall of the mounting cavity 201 via a bearing. The two storage cavities b208... 8. Limiting grooves 209 are provided at the bottom of the inner wall; the positions of the two storage cavities b208 and the two mounting cavities 201 correspond one-to-one, and a sliding groove 210 is provided between the mounting cavity 201 and the storage cavity b208; the bottom of the L-shaped slider 4 extends into the storage cavity b208 and is fixedly connected to a spring limiting block 401. A magnet 402 is provided on one side of the spring limiting block 401, and a spring sheet 403 is provided inside the spring limiting block 401. One end of the magnet 402 is fixedly connected to the spring limiting block 401.

[0036] When writing on the extended blackboard 302 on one side of the mounting plate 301, it is inconvenient for students sitting on the other side of the classroom to see. The user can control the electric telescopic rod 205 to lower the moving platform 204, and then transmit the content on the corresponding extended blackboard 302 to the corresponding display screen a7 through the corresponding camera a207, so that students on the other side of the classroom can see it. When explaining content related to the displayed items, the image of the items can also be displayed on the display screen b701 through the camera b504, so that students can learn and observe better.

[0037] Among them, the top and bottom of the inner walls of the two storage cavities a102 are provided with limiting grooves 104, and limiting magnets 105 are fixedly connected in the limiting grooves 104. The top and bottom of the two mounting plates 301 are fixedly connected with iron limiting sliders 303, and the iron limiting sliders 303 and the limiting grooves 104 are slidably connected. Limiting pull plates 3 are fixedly installed on one side of the two mounting plates 301. Iron blocks 306 are fixedly installed on both sides of the cabinet 1. Limiting slots 308 are provided on one side of the two mounting plates 301, and magnetic strips 304 are fixedly connected to one side of the inner wall of the limiting slots 308. Wheels 307 are fixedly connected to the bottom of the two limiting pull plates 3. Magnet blocks 305 are fixedly installed on one side of the two limiting pull plates 3, and the magnet blocks 305 are magnetically connected to the iron blocks 306.

[0038] Users can write on the blackboard 702 with chalk. When the blackboard 702 is full, the limit pull plates 3 on both sides of the cabinet 1 are pulled to release the limit of the magnet block 305 and the iron block 306, and the limit pull plates 3 slide out along the limit groove 209 until the extended blackboard 302 on one side of the mounting plate 301 is fully extended. At this time, the limit slider 303 and the limit magnet 105 are magnetically connected. Then, the servo motor a202 is turned on, and the lead screw 203 is rotated by the servo motor a202, thereby driving the L-shaped slider 4 and the moving platform 204 to move along the slide groove 210 until the moving platform 204 moves to the end of the slide groove 210. The magnet 402 of the spring limit block 401 at the bottom of the L-shaped slider 4 moves into the limit groove 308 and is attached to the magnet strip 304. At this time, the magnet strip 304 and the magnet 402 are magnetically connected to fix the mounting plate 301.

[0039] The working principle is as follows: In use, open the protective door on one side of the storage compartment 103, then take out the smaller items to be displayed. Attach a piece of double-sided tape to the top of each of the multiple turntables 602, then press the items onto the tape one by one. Next, control the electric push rod 603 to extend, causing the equipment box 6 and the turntables 602 to rise and move to the side of the camera b504, capturing images of the items on the turntables 602. The images are then transmitted in real-time to the display screen b701 via the camera 504. Simultaneously, activating the motor 601 rotates the turntables 602 and the items, allowing the camera b504 to focus on them. The object is photographed from 360 degrees to allow students to observe it in more detail. After observing the first object, the first electric push rod 603 is retracted and the second electric push rod 603 is raised. Then, the servo motor b5 is activated, which rotates the screw 501, causing the slider 502 to move the camera b504 along the direction of the screw 501, bringing the camera b504 closer to the second object for photographing. In addition, the LED light 503 provides a light source for the camera b504.

[0040] Furthermore, the user can write on the blackboard 702 with chalk. When the blackboard 702 is full, the user pulls the limiting plates 3 on both sides of the cabinet 1 to release the limiting of the magnet block 305 and the iron block 306, and the limiting plates 3 slide out along the limiting groove 209 until the extended blackboard 302 on one side of the mounting plate 301 is fully extended. At this time, the limiting slider 303 and the limiting magnet 105 are magnetically connected. Then, the servo motor a202 is turned on, and the lead screw 203 is rotated by the servo motor a202, thereby driving the L-shaped slider 4 and the moving platform 204 to move along the slide groove 210 until the moving platform 204 moves to the end of the slide groove 210. The magnet 402 of the spring limiting block 401 at the bottom of the L-shaped slider 4 moves into the limiting groove 308 and is attached to the magnet strip 304. At this time, the magnet strip 304 and the magnet 402 are magnetically connected to fix the mounting plate 301.

[0041] In addition, by setting the spring plate 403, when the limiting slot 308 is not aligned with the magnet 402, the magnet 402 can move away from the mounting plate 301, so as to prevent the spring limiting block 401 from squeezing the mounting plate 301 and causing the mounting plate 301 to deform, and the magnet 402 has inclined surfaces on both sides.

[0042] Furthermore, when writing on the extended blackboard 302 on one side of the mounting plate 301, it is inconvenient for students sitting on the other side of the classroom to see. The user can control the electric telescopic rod 205 to lower the moving platform 204, and then transmit the content on the corresponding extended blackboard 302 to the corresponding display screen a7 through the corresponding camera a207, so that students on the other side of the classroom can see it. When explaining content related to the displayed items, the image of the items can also be displayed on the display screen b701 through the camera b504, so that students can learn and observe better.

[0043] In addition, a controller is installed on one side of the cabinet 1. The controller can control the start and stop of the servo motor a202, the electric telescopic rod 205, the camera a207, the servo motor b5, the LED light 503, the camera b 504, the electric motor 601, the electric push rod 603, the display screen a7 and the display screen b701.
