[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 2 This invention provides a portable electronic textbook, comprising a controller 505, a projector 6 at the bottom of the controller 505 for projecting learning content onto any platform, a camera 601 on one side of the projector 6 for capturing images of the learning content and answer questions, a recognition system for comparing the images captured by the camera 601 with the images before and after answering questions to obtain the answer, and an analysis system for comparing the answer with the correct answer to determine whether the answer is correct or incorrect.

[0027] The controller 505 is mounted and fixed by the mounting bracket 5;

[0028] It also includes an adjustment mechanism connected to the mounting bracket 5, used to adjust the angle of the mounting bracket 5 to meet the projection angle of the projector 6. It can be explained that the controller 505 is mounted on any learning platform via the mounting bracket 5, which can be a desk or study table. The angle of the controller 505 is adjusted via the adjustment mechanism, the projector 6 and camera 601 are activated, and the projector 6 projects learning content onto the learning platform. After projection, the camera 601 captures the projected content. Students answer questions based on the projected content. After answering, the camera 601 captures the answer again and uploads the captured answer to the controller 505. The recognition system compares the images captured by the camera 601 before and after the answer to obtain the answer. Finally, the analysis system compares the answer with the correct answer to determine whether the answer is correct or not. This embodiment of the invention replaces existing learning computers or tablets by setting up a projector 6 and a camera 601, thus protecting students' eyesight from the blue light emitted by computer screens.

[0029] As a further embodiment of the present invention, an adjustment box 501 is provided between the mounting frames 5, and a half gear 506 is rotatably arranged inside the adjustment box 501. The bottom of the half gear 506 is fixedly connected to the controller 505. A guide plate 503 is slidably arranged between the mounting frames 5, and a rack plate 504 that meshes with the half gear 506 is provided at the bottom of the guide plate 503.

[0030] Specifically, in this embodiment, when installing the controller 505, in order to adjust the angle between the projector 6 and the camera 601, the guide plate 503 is slid between the mounting brackets 5. During the sliding process, the guide plate 503 drives the half gear 506 to rotate through the rack plate 504. The half gear 506 then synchronously drives the controller 505 to rotate, thereby realizing the angle adjustment between the projector 6 and the camera 601.

[0031] In addition, a handle 502 is fixedly installed on the guide plate 503. The operator can push and pull the handle 502 to drive the guide plate 503 to slide, thereby adjusting the angle of the controller 505.

[0032] Please see Figure 3 As a further embodiment of the present invention, the adjustment mechanism includes a base 1 disposed on the learning platform, a support platform 2 disposed on the base 1, and an mounting plate 202 disposed on the support platform 2. The mounting plate 202 is detachably and fixedly connected to the mounting frame 5 through a telescopic bracket.

[0033] In one embodiment of the present invention, a telescopic bracket is provided at the bottom of the mounting frame 5, so that when the height of the controller 505 is adjusted, the telescopic bracket can be adjusted to extend or retract, so that the height of the projector 6 and the camera 601 meets the projection and imaging range.

[0034] Furthermore, two sets of limiting plates 204 are arranged opposite each other on the mounting plate 202, and the two limiting plates 204 surround to form a mounting groove. A base plate 203 is provided in the mounting groove. One end of the limiting plate 204 is fixedly connected to the mounting plate 202 by a pin, and the other end is fixedly connected to the base plate 203 by a pin. The base plate 203 is connected to the telescopic bracket.

[0035] It can be explained that the telescopic bracket base plate 203 is installed in the mounting groove formed by two sets of limiting plates 204, and the base plate 203 is fixed by the limiting plates 204 and the pins, which facilitates disassembly and assembly and provides higher stability.

[0036] Please see Figure 4 The base plate 203 is fixedly provided with a positioning plate 3, and the telescopic bracket includes a telescopic rod 301 that is rotatably arranged on the positioning plate 3. The ends of the telescopic rods 301 on both sides are rotatably provided with telescopic plates 303, wherein the ends of the telescopic plates 303 are rotatably connected to the mounting frame 5. It can be explained that when adjusting the height of the mounting frame 5, the telescopic rod 301 is first rotated to form a certain angle with the positioning plate 3, so that the telescopic rod 301 is flipped in the direction away from the positioning plate 3, and then the telescopic plate 303 is flipped again in the direction away from the telescopic rod 301, so that the distance between the mounting frame 5 and the positioning plate 3 is increased, thereby realizing the height adjustment of the controller 505.

[0037] In addition, a slot 302 is formed between the two telescopic rods 301 for storing the telescopic plate 303. When storing the portable electronic textbook, the telescopic rods 301 are first flipped toward the positioning plate 3, and then the telescopic plate 303 is flipped toward the telescopic rods 301, so that the telescopic plate 303 is stored in the slot 302, achieving a folding effect, occupying less volume and facilitating storage.

[0038] Please see Figure 5 As a further embodiment of the present invention, the support platform 2 is provided with a guide groove 201, and the mounting plate 202 is fixedly connected to the guide frame 404 which is slidably arranged in the guide groove 201.

[0039] A drive mechanism is also provided between the support platform 2 and the base 1. The drive mechanism is connected to the guide frame 404 to drive the mounting plate 202 to slide on the support platform 2. Specifically, in this embodiment, the mounting plate 202 is driven to slide on the support platform 2 by the drive mechanism, thereby realizing the horizontal position adjustment of the controller 505.

[0040] The driving mechanism includes a driving housing 4 disposed between the support platform 2 and the base 1. A screw 402 is rotatably disposed between the driving housing 4 and the screw 402. A handle 401 is provided at the end of the screw 402. A nut 403 is screwed onto the screw 402. The nut 403 is fixedly connected to the guide frame 404. Specifically, in this embodiment, the screw 402 is driven to rotate by rotating the handle 401. During the process of the nut 403 moving on the screw 402, the guide frame 404 is moved to achieve the horizontal position adjustment of the mounting plate 202 and the controller 505.

[0041] The working principle of the portable electronic textbook provided by this invention is as follows: The controller 505 is installed on any learning platform (such as a desk or study table) via the mounting bracket 5. The angle of the controller 505 is adjusted using an adjustment mechanism. The projector 6 and camera 601 are activated. The projector 6 projects learning content onto the learning platform. After projection, the camera 601 captures the projected content. Students answer questions based on the projected content. After answering, the camera 601 captures the answers again. The camera 601 uploads the captured answers to the controller 505. A recognition system compares the images captured by the camera 601 before and after the answers. After obtaining the answer, the system compares the answer with the correct answer to determine whether the answer is correct or not. By rotating the handle 401, the screw 402 is driven to rotate. As the nut 403 moves along the screw 402, it drives the guide frame 404 to move, thereby adjusting the horizontal position of the mounting plate 202 and the controller 505. When adjusting the height of the mounting frame 5, the telescopic rod 301 is first rotated to form a certain angle with the positioning plate 3, so that the telescopic rod 301 flips away from the positioning plate 3. Then, the telescopic plate 303 is flipped away from the telescopic rod 301 again, increasing the distance between the mounting frame 5 and the positioning plate 3, thereby adjusting the height of the controller 505.

[0042] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
