Description

Technical Field

[0001] The utility model relates to the technical field related to teaching records, and in particular to a device for combining teaching record videos with courseware backgrounds. Background Art

[0002] Teaching video is an educational tool that records the teaching process and presents classroom content in the form of video. This form of video is helpful for students to learn remotely, learn independently, and for teachers to demonstrate their teaching skills. Through the video, students can watch the teaching content through digital devices at any time and any place, which improves the flexibility and convenience of learning. Teachers can demonstrate teaching skills, classroom interaction and professional knowledge in the video, so that the audience can understand the teaching process more intuitively. This form also provides a platform for teachers to share experiences and exchange teaching methods. In general, teaching video promotes the sharing of teaching resources and the popularization of teaching content through digital means, and provides a wider communication channel for teaching. In the process of use, when recording teaching videos, a projector is needed to project the background of the courseware so that the audience can see the teaching content more intuitively. During the projection, the movement of people or some indoor layouts may block the projection, resulting in an incomplete background of the recorded courseware, affecting the recording quality of the teaching video. Therefore, a device combining teaching video with the background of the courseware is particularly needed.

[0003] However, in the use of most existing teaching recording devices, teachers may need to express teaching content through oral description, which may not be as clear and intuitive as through visualization, and some viewers may have limited understanding of oral descriptions. Especially when it comes to some complex concepts or processes, the lack of graphic support may lead to difficulties in understanding. Utility Model Content

During projection, the movement of people or some indoor layouts may block the projection, resulting in incomplete courseware background after recording, affecting the recording quality of the teaching video.

[0005] To achieve the above-mentioned purpose, the utility model provides a device for combining teaching video recordings with courseware backgrounds, including a recording camera and a courseware projector, the bottom surface of the recording camera is fixedly connected to the courseware projector, the outer surface of the recording camera is provided with a background projection mechanism, and the outer surface of the recording camera is provided with an adjustment and fixing mechanism.

[0023] Furthermore, the background projection mechanism 3 includes a mounting post 301, a magnetic shell 302, a transparent background plate 303, a sliding clamp 304, a connecting shell 305 and a projection background plate 306. The outer surface of the recording camera 1 is fixedly connected with the mounting post 301, the outer surface of the mounting post 301 is slidably connected with the magnetic shell 302, the inner surface of the magnetic shell 302 is fixedly connected with the transparent background plate 303, the outer surface of the magnetic shell 302 is snap-connected with the sliding clamp 304, and the outer surface of the sliding clamp 304 is fixedly connected with the connecting The housing 305 is connected to the inner surface of the housing 305 and is fixedly connected with a projection background plate 306.

The magnetic housing 302 is rotated downward and slid until it is adsorbed to the lens of the recording camera 1. The adsorption frame 401 on the recording camera 1 is used to fix the current position. The transparent background board 303 on the magnetic shell 302 is drawn with a background layer. The recording camera 1 assists teaching through the background layer when recording teaching videos. Since the background layer directly covers the front of the lens of the recording camera 1 and will not be blocked, it is ensured that the background layer always has the function of assisting teaching. The magnetic shell 302 is clamped with a sliding clamp 304. The sliding clamp 304 is made of plastic and has a certain elasticity. It can be stuck on the magnetic shell 302 and change its position freely. An auxiliary pattern for teaching is drawn on the projection background board 306. When the projection background board 306 on the sliding clamp 304 is aligned with the output end of the courseware projector 2, the courseware projector 2 projects the auxiliary pattern to the teaching area for assisting teaching.

[0026] Furthermore, the input end of the recording camera 1 is slidably connected to the transparent background board 303, and the output end of the courseware projector 2 is slidably connected to the projection background board 306. When recording the teaching video, the recording camera 1 assists the teaching through the background layer. Since the background layer directly covers the front of the lens of the recording camera 1 and will not be blocked, the teaching auxiliary background is projected through the transparent background board 303 and the courseware projector 2 so that the teacher can also see it and assist in teaching. In this way, the effect of combining the courseware background assistance while recording the teaching can be added.

Through the arrangement of the adsorption frame 401, the limiting frame 402, the sliding plate 403, the limiting block 404 and the fixed shell 405, during use, The magnetic shell 302 rotates downward and slides until it is adsorbed onto the adsorption frame 401 on the recording camera 1 to fix the current position. The sliding plate 403 can slide freely between the limit frame 402 and the recording camera 1, and the limit block 404 limits the range of movement to prevent it from falling. The fixed shell 405 can move with the sliding plate 403. When the magnetic shell 302 is inside the fixed shell 405, the magnetic shell 302 will adsorb the fixed shell 405 to prevent the magnetic shell 302 from rotating to the lens of the recording camera 1.

During use, the recording camera 1 is used to record teaching videos, and the courseware background is directly covered on the lens of the recording camera 1 through the background projection mechanism 3. The courseware projector 2 projects the teaching courseware auxiliary background through the background projection mechanism 3. The adjustment fixing mechanism 4 is used to adjust and switch the background projection mechanism 3. The magnetic shell 302 can slide and rotate freely on the mounting column 301. The magnetic shell 302 is rotated to the bottom and slid until it is adsorbed on the adsorption frame 401 on the recording camera 1 to fix the current position. The transparent background plate 303 on the magnetic shell 302 is drawn with a background layer. The magnetic shell 302 is clamped with a sliding clamp 304. The projection background plate 306 is drawn with an auxiliary pattern for teaching. When the projection background on the sliding clamp 304 When the background board 306 is aligned with the output end of the courseware projector 2, the courseware projector 2 projects the auxiliary pattern onto the teaching area for auxiliary teaching, and the magnetic shell 302 is rotated downward and slid until it is adsorbed onto the adsorption frame 401 on the recording camera 1 to fix the current position. The sliding plate 403 can slide freely between the limit frame 402 and the recording camera 1, and the range of movement is limited by the limit block 404 to prevent it from falling. The fixed shell 405 can move with the sliding plate 403. When the magnetic shell 302 is inside the fixed shell 405, the magnetic shell 302 will adsorb the fixed shell 405 to prevent the magnetic shell 302 from rotating to the lens of the recording camera 1. The magnetic shell 302 is taken out and rotated by moving the fixed shell 405 to adsorb the recording camera 1, thereby completing a device combining a teaching video with a courseware background.
