[0002] With the widespread adoption of information-based teaching, interactive displays have become a crucial tool for enabling teacher-student interaction in modern classrooms. Traditional teaching displays are often fixed. This rigid structure results in a small horizontal coverage area. During collaborative group learning, most interactions occur within a 4-6 meter multi-person operation area, making existing teaching aids difficult to meet. Furthermore, when conducting personalized tests or group competitions, the wide viewing angles of traditional display devices expose the screen content to the field of view of non-operators within the surrounding area, making the screen display easily visible to surrounding students, making it difficult to ensure fair teaching. Consequently, existing teaching aids are unable to meet the actual needs of teaching. Summary of the Invention

[0013] As a further solution of the present invention: the working method of the present invention comprises the following steps:

[0014] Step 1: The driving assembly drives the installation assembly to move, and the lifting rod assists in adjusting the screen position to assist in teaching operations;

[0033] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0034] like Figures 1 to 9 As shown, an embodiment of the present invention provides an educational teaching auxiliary device with adjustable screen, please refer to Figure 1 , including a base 101, a plurality of running wheels are rotatably mounted on the bottom of the base 101 to facilitate the movement of the entire device. If necessary, a running control mechanism can be set in the base 101 with reference to the prior art to control the rotation and direction of each running wheel, thereby realizing automatic movement of the device; in a specific implementation, a counterweight block can be set in the base 101 to improve the stability of the device during use;

[0035] A column 102 is fixedly mounted on the top of the base 101. Figure 1 and Figure 9 The column 102 is divided into a fixed section 1021 located below and fixedly connected to the base 101, and a movable section 1022 arranged above the fixed section 1021. A lifting push rod 1023 is fixedly installed inside the fixed section 1021, and the output end of the lifting push rod 1023 is fixedly connected to the bottom of the movable section 1022; thereby realizing the lifting and displacement adjustment of each device structure thereon; in specific implementation, a redundant limit switch can be set inside the column 102. When abnormal resistance is detected, the lifting and lowering will be automatically stopped and an audible and visual alarm will be triggered, thereby improving safety during use and avoiding forced lifting operations when there are obstacles on the top of the equipment or when there are debris attached, which may cause damage to the device.

[0036] In one embodiment, see Figure 1 and Figure 2 A sliding support assembly 2 is provided in the middle of the column 102. The sliding support assembly 2 includes a supporting ring. One side of the supporting ring is fixedly connected to the main sliding frame 201 through a connecting rod 204. The middle part of one side of the main sliding frame 201 is fixedly connected to the main sliding platform 2031. The middle part of the main sliding platform 2031 is slidably provided with a screen mounting mechanism 3. The screen mounting mechanism 3 includes a driving assembly 301 and a mounting assembly 303. The mounting assembly 303 is shifted and adjusted by the driving assembly 301. The mounting assembly 303 includes a mask 3031. One side of the inner wall of the mask 3031 A mounting frame 304 is slidably connected, and a display screen 305 is fixedly mounted on the inner wall of the mounting frame 304. The shield 3031 is made of opaque material, and the inner cavity of the shield 3031 is larger than the size of the mounting frame 304, so that the mounting frame 304 and the screen can rotate and shift within the shield 3031. In a specific implementation, a light-absorbing velvet cloth can be fixedly connected to the inner layer of the shield 3031 to reduce damage to the display screen 305 during the sliding and shifting process. Furthermore, a dust cover can be snapped onto the open end of the shield 3031 to prevent dust from contaminating the display screen 305.

[0037] In one embodiment, see Figure 7 and Figure 8 A push rod 3032 is fixedly installed at the bottom of the inner wall of the mask 3031, and the output end of the push rod 3032 is rotatably connected to the middle part of the mounting frame 304; in the teaching process, students are often required to cooperate in answering questions to complete the teaching work, and for the existing screen structure, when a student is answering a question, students in adjacent positions can see the question and the student's answer and operation, which in turn affects the subsequent question-and-answer teaching of other students; therefore, this application sets a mask 3031, and when students answer questions independently or perform private operations, the driving component 301 drives the screen to move backward along the main sliding frame 201, so that the screen completely enters the cavity of the mask 3031. The edge of the mask 3031 is made of flexible covering material, which automatically forms a surround shielding during the screen retraction process, blocks the side view through physical isolation, effectively prevents information leakage, avoids other students from snooping, and ensures the orderly progress of teaching operations; a sensor is integrated on the top of the mask 3031 to automatically sense the position of surrounding students and ambient brightness, and dynamically adjust the shielding range of the mask 3031 and the screen brightness to improve ease of use; in a specific embodiment, the display content of the display screen 305 and the control system inside the device can be shared in real time to another operating end through a signal line or a remote communication module, so that the teacher can remotely control it and understand the student's operation status in real time.

[0038] In one embodiment, to further adjust the screen posture, please refer to Figure 8, adjustment push rods 3033 are provided on the upper and lower sides of the push rod 3032, and the output ends of the two adjustment push rods 3033 are fixedly connected to the docking shaft. Two adjustment slots 3034 arranged up and down are opened on one side of the mounting frame 304, and the two docking shafts are slidingly connected to the two adjustment slots 3034 respectively, that is, the output ends of the two adjustment push rods 3033 form a structure similar to a sliding hinge with the adjustment slot 3034 through the docking shaft. By changing the propulsion stroke of the two adjustment push rods 3033, the pitch adjustment of the mounting frame 304 and the screen posture is realized, which is convenient for users to operate.

[0039] In one embodiment, see Figure 2 In order to extend the range of motion of the driving assembly 301 so as to facilitate the operation of students in the same row, two auxiliary sliding frames 202 are rotatably connected to the two sides of the main sliding frame 201 through two bearing shafts 207. One side of the two auxiliary sliding frames 202 is fixedly connected to an auxiliary sliding platform 2032. The size and structure of the auxiliary sliding platform 2032 are consistent with the size and structure of the main sliding platform 2031. The two auxiliary sliding frames 202 can be unfolded and moved to a position flush with the main sliding frame 201 by rotation. At this time, the auxiliary sliding platform 2032 is aligned with the main sliding platform 2031, so that the driving assembly 301 can move freely along the main sliding platform 2031 and the auxiliary sliding platform 2032; in order to limit the two auxiliary support brackets when not in use, two contact frames 205 are fixedly connected to the other side of the support ring, and one end of the two contact frames 205 is fixedly installed with a contact plate, and the inside of the contact plate is fixedly installed with a positioning magnet 206. When not in use, the two auxiliary sliding frames 202 are folded and retracted, so that the two positioning magnets 206 are magnetically adsorbed and connected to the middle part of the two auxiliary sliding frames 202 respectively, and the edge of the contact plate is fixedly connected with a soft pad to reduce friction damage between the auxiliary sliding frame 202.

[0040] In one embodiment, see Figure 3 In order to achieve the limiting and fixing of the auxiliary sliding frame 202, both ends of the main sliding frame 201 are fixedly connected with front rings 212, and the inner walls of the two front rings 212 are fixedly connected with plug-in plates 211. One end of the two auxiliary sliding frames 202 is fixedly connected with rear rings 213, and one end of the two plug-in plates 211 is respectively set corresponding to the two rear rings 213. When the auxiliary sliding frame 202 is flipped over and flush with the main sliding frame 201, the plug-in plates 211 are pushed and plugged into the rear rings 213 to achieve the limiting of the auxiliary sliding frame 202.

[0041] In one embodiment, see Figure 4, because after the auxiliary sliding frame 202 is flipped and unfolded, its end is too far away from the column 102, and the driving component 301 actively screen mounting mechanism 3 as a whole has a large dead weight, in order to improve the bearing capacity of the auxiliary mounting frame 304 and avoid its fracture and deformation, the present application rotatably installs two traction rings 209 on the top of the column 102, and one end of the top of the two auxiliary sliding frames 202 is fixedly connected to a hanging ring 208, and the two traction rings 209 are fixedly connected to the two hanging rings 208 by a hanging cable 210. The hanging cable 210 is woven stainless steel and has a polyurethane coating on the surface to prevent wear. When the auxiliary mounting frame 304 is flipped open, it drives the hanging cable 210 to move and at the same time The dynamic traction ring 209 rotates by itself, and the length of the lifting cable 210 is sufficient. When the sub-mounting frame 304 is flipped open to be flush with the main sliding frame 201, the lifting cable 210 is in a tensioned state; the carrying capacity of the sub-mounting frame 304 is improved by the traction and pulling effect of the lifting cable 210; in specific implementation, the motor and winch encoder and other structures can be fixedly installed at the position of the traction ring 209 to realize automatic winding and tightening of the lifting cable 210, and the bearing pressure of the sub-sliding frame 202 can be detected in real time by the sensor. In this way, when the bearing pressure is too large, the operator is reminded to pay attention and make adjustments and maintenance in time to avoid the safety hazard caused by the breakage of the sub-sliding frame 202.

[0042] In one embodiment, see Figure 6 The driving component 301 of the present application includes a driving frame 3011, and a docking groove is opened on one side of the driving frame 3011. The inner wall of the docking groove is slidably connected to the main sliding table 2031. A plurality of driving motors 3012 are fixedly installed on one side of the docking groove. The output ends of the plurality of driving motors 3012 are fixedly connected to driving rollers 3013. One side of the driving roller 3013 is in close contact with the main sliding table 2031. The outer wall of the driving roller 3013 is fixedly connected to a friction pad, so as to increase the friction resistance between the driving roller 3013 and the main sliding table 2031. The friction between the pressing roller and the friction pad and the main sliding frame 201 drives the driving frame 3011 to move as a whole.

[0043] In one embodiment, in order to facilitate adjustment of the screen's posture to meet the needs of different teaching environments, a steering motor is fixedly installed inside the driving frame 3011 , and the output end of the steering motor is fixedly connected to a load-bearing steering column 3014 .

[0044] In one embodiment, see Figure 5The cam 3024 is fixedly mounted on the inner wall of the cam 3022 and the vertical guide rail 3023 is slidably mounted on the inner wall of the cam 3023. The cam 3024 is slidably mounted on the inner wall of the cam 3023. One end of the cam 3024 is fixedly connected to the cam 3024 and the output end of the cam 3024 is fixedly connected to the cam 3024. The cam 3024 is fixedly mounted on the inner wall of the cam 3022 and the vertical guide rail 3023. The cam 3024 is fixedly mounted on the inner wall of the cam 3023. The cam 3024 is fixedly mounted on the inner wall of the cam 3023.

[0045] When the present invention is in use, the entire device is moved to the use position by manual pushing or the driving of the built-in travel control mechanism. The driving motor 3012 drives the driving roller 3013 to rotate, thereby driving the additional shifting assembly 302 and the installation assembly 303 to slide and shift along the main sliding platform 2031. The lifting push rod 1023 drives the movable section 1022 to move up and down to adjust the position of the display screen 305. When the display screen 305 is in the appropriate position, the display screen 305 starts to display teaching content to assist teaching operations.

[0046] When the lateral movement distance of the display screen 305 needs to be extended to meet the needs of group collaborative teaching of multiple students in the same row, the auxiliary sliding frame 202 can be flipped open until the auxiliary sliding frame 202 is flush with the main sliding frame 201, and then the plug board 211 is pushed to move so that its end passes through the rear ring 213 to fix the auxiliary sliding frame 202; then the driving assembly 301 drives the display screen 305 to pass in front of each student in turn, and the display screen 305 is reset after the student completes the operation;

[0047] When students need to perform separate screen operations to complete answering teaching, the driving component 301 and the lifting push rod 1023 drive the display screen 305 to move to the student position, and the push rod drives the screen to retract, and the mask 3031 is used to cover the screen to prevent neighboring students from looking at it and affecting the answering; when a student finishes answering the question, the driving component 301 drives the screen to continue to move horizontally, so that students in neighboring positions can complete the answering in turn, and then the driving component 301 drives the display screen 305 to reset, thereby achieving assistance to teaching.

[0048] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
