DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 , the utility model provides a technical solution:

[0021] A multimedia courseware teaching display device comprises two groups of supporting plates 1 and a multimedia display screen 2, the tops of the two groups of supporting plates 1 are respectively fixedly connected with upright poles 3, the interiors of the two groups of upright poles 3 are respectively provided with cavities 4, the interiors of the two groups of cavities 4 are respectively provided with lifting components 5 for adjusting the height of the multimedia display screen 2, an installation frame 6 is fixedly connected to the outer wall of the multimedia display screen 2, a positioning shell 7 is fixedly connected to the side wall of one side of the installation frame 6, the two sides of the positioning shell 7 are respectively connected to the moving end of the lifting component 5, and two groups of whiteboards 8 are arranged on the inner wall of the positioning shell 7. By arranging the supporting plates 1, the upright poles 3, the cavities 4, the lifting components 5, the installation frame 6 and the positioning shell 7, the multimedia display screen 2 is provided with a plurality of lifting components 5, and the plurality of lifting components 5 are provided with a plurality of lifting components 5. The height of the multimedia display screen 2 can be adjusted by using the housing 7. By adjusting the height of the multimedia display screen 2, the teacher can ensure that each student can clearly see the content on the multimedia display screen, thereby avoiding distraction or decreased learning efficiency due to poor sight. Different teaching places (such as classrooms, conference rooms, lecture halls, etc.) may have different requirements for the height of the multimedia display screen 2. The height adjustment function of the device enables it to adapt to various teaching environments and has a wide range of applicability. Whether it is to adapt to students of different heights or to meet the display needs in different teaching scenarios, the height adjustment function can provide great convenience;

[0022] The lifting assembly 5 includes a ball screw 501, the top and bottom of which are rotatably mounted on the inner top and inner bottom of the cavity 4, respectively. The top of the ball screw 501 passes through the vertical rod 3 and is connected to a driving motor 502. A lifting block 503 is threadedly connected to the outer wall of the ball screw 501.

[0023] Specifically, by setting the driving motor 502, the ball screw 501 and the lifting block 503 for coordinated use, the output shaft of the driving motor 502 in operation can drive the ball screw 501 to rotate in a forward or reverse direction, thereby driving the lifting block 503 to reciprocate along the axial direction of the ball screw 501;

[0024] It also includes a connecting rod 9, which serves as the moving end of the lifting assembly 5. One end of the connecting rod 9 is fixedly connected to one side wall of the lifting block 503, and the other end of the connecting rod 9 is fixedly connected to one side wall of the positioning shell 7. When the lifting block 503 reciprocates along the axial direction of the ball screw 501, the positioning shell 7, the mounting frame 6 and the multimedia display screen 2 can be driven by the connecting rod 9 to adjust the height, so that the teacher can ensure that every student can clearly see the content on the multimedia display screen 2.

[0025] A through slot 10 is provided on one side wall of the vertical rod 3, and the outer wall of the connecting rod 9 is slidably connected to the inner wall of the through slot 10. By setting the through slot 10 and the connecting rod 9 in cooperation, the lifting block 503 is limited, making it more stable during operation, which is conducive to improving the stability of the device;

[0026] The driving motor 502 is fixedly connected to the top of the vertical pole 3, and one end of the output shaft of the driving motor 502 is fixedly connected to the top of the ball screw 501. The driving motor 502 is set as a forward and reverse stepping motor. The stepping motor has very high precision and can accurately control the position and speed of the motor by controlling the number and frequency of current pulses. In the multimedia courseware teaching display device, this means that the height of the multimedia display screen 2 can be accurately adjusted to ensure that each lifting and lowering can reach the preset precise position, which is very important for ensuring the stability and reliability of the teaching effect;

[0027] Two groups of loudspeakers 11 are fixedly mounted on the inner wall of the mounting frame 6. The two groups of loudspeakers 11 are symmetrically arranged. The loudspeakers 11 can amplify and transmit sound, ensuring that in a larger teaching environment, each student can clearly hear the teacher's explanation or the sound of the media content, which helps to improve students' attention and enhance learning effects, especially when it is necessary to emphasize key information or conduct listening training. In addition, the loudspeakers 11 can play various sound effects, such as background music, environmental sound effects, etc., to add more diversified elements to the teaching presentation. This interactive experience can stimulate students' interest in learning and make teaching more vivid and interesting, thereby improving students' participation and enthusiasm;

[0028] Two groups of slide grooves 12 are respectively provided at the inner top and the inner bottom of the positioning shell 7, and the top and the bottom of the two groups of whiteboards 8 are respectively fixedly connected with sliders 13 adapted to the slide grooves 12, and the sliders 13 are slidably connected to the inside of the slide grooves 12. The whiteboard 8 provides more writing and display space, so that the teaching display device has stronger versatility. Teachers can use the whiteboard 8 to write at any time according to the teaching content and needs. The whiteboard 8 can slide freely, so that teachers can easily switch between different whiteboards 8 to display different teaching contents.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
