Technical Field

[0001] The present invention relates to the technical field of university education, and in particular to a university education and teaching management information display device with touch feedback. Background Art

[0002] Higher education enables students to quickly accumulate knowledge and master new technologies. It also broadens students' horizons and increases their opportunities. In the process of higher education, education and teaching management is a very important part. It covers basic school information, such as area, location, etc. It can also cover test information, score information, etc. When displaying education and teaching management information, a display screen is needed. When the display screen is working, it visualizes education information, teaching material information and other data, so that it can be displayed visually and is easy to read.

[0003] During the use of the education and teaching management information display screen, at night, there will be no students in front of the display screen, and the display screen does not need to work at this time, but at the same time, birds may stay on the device, and bird droppings will corrode the device, shortening the service life of the device.

[0004] In order to overcome the above defects, prior art 1 (Chinese patent application with application number CN202211210110.1 and application date CN202211210110.1) provides a display screen protection device, which can shield the surface of the display screen when the display screen is in a closed state to prevent direct sunlight or rain from directly impacting the display screen, and at the same time prevent the display screen from being broken by impact of foreign objects, thereby protecting the surface of the display screen and extending the service life of the display screen.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the university education and teaching management information display device with touch feedback adopts a new structural design, and the protective cloth can be quickly pulled open by the night protection component, so as to protect the display screen when the display screen is not working at night. At the same time, a cleaning component is also provided, and the surface of the display screen can be cleaned by a brush plate to remove the dust on the surface of the display screen. In addition, an air jet component is provided, so that the dust after cleaning is blown away by the air flow, thereby optimizing the cleaning effect. The specific contents are as follows:

[0018] (1) When using the touch-sensitive feedback information display device for higher education and teaching management, the staff completes the input of information by touching the display screen. At the same time, the display screen has the function of touch feedback, which makes the input process smoother. At the same time, a connecting rod and a connecting shaft are provided. The protective cloth on the surface of the connecting shaft is opened by the connecting rod to protect the display screen and prevent the display screen from being damaged.

[0019] Furthermore, when the connecting shaft rotates inside the fixed block, the torsion spring will be stretched, and then when the driving motor drives the threaded rod to rotate and the connecting rod moves back, the protective cloth and the connecting shaft lose tension. At this time, the connecting shaft rotates inside the fixed block under the action of the torsion spring. When the connecting shaft rotates, the protective cloth will be rolled up to facilitate the subsequent use of the protective cloth.

[0020] (2) The touch-feedback information display device for university education and teaching management, when the connecting rod moves, will drive the moving block and the force-bearing block to move synchronously. At this time, the force-bearing block will intermittently contact the protrusion. At this time, the force-bearing block, the moving block and the brush plate will make reciprocating linear motion in the vertical direction under the action of the thrust, the column and the first spring, and then the brush plate will play the role of cleaning the display screen, so that the dust on the surface of the display screen falls off.

[0021] Furthermore, after long-term use, dust will accumulate on the surface of the brush plate. At this time, the brush plate can be directly pulled out from the moving block, and after cleaning the brush plate, the brush plate can be inserted into the moving block, so that the brush plate is always in the best cleaning state, ensuring work efficiency;

[0022] (3) In the device for displaying information on education and teaching management of higher education with touch feedback, when the slider moves left and right, the slider will drive the second magnet to move synchronously. At this time, the second magnet will intermittently approach the first magnet, and then the working plate will drive the squeezing plate to intermittently squeeze the airbag under the action of the repulsive magnetic force, the cross bar and the second spring. When the airbag is squeezed, the airbag will spray through the air supply pipe and the air nozzle. When the air nozzle sprays, the dust on the surface of the display screen can be blown away. The air nozzle and the brush plate work together to achieve a better cleaning effect.

[0023] Furthermore, when the airbag is not squeezed, the airbag inhales air through the lower pipe, and during the process of the airbag exhaling and inhaling, the one-way valve directs the airflow from the lower pipe to the air nozzle, thereby ensuring the working stability of the airbag and the air nozzle.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1: By setting a night protection component, the display screen 9 can be covered by a protective cloth at night, such as Figure 1-Figure 3 As shown, it includes an outer frame 1, a driving machine is fixedly connected to the surface of the outer frame 1, and a threaded rod 2 is fixedly connected to the output end of the driving machine, and a support plate 3 is fixedly connected to the surface of the outer frame 1, and a display screen 9 is fixedly connected to the surface of the outer frame 1, a slider 5 is threadedly connected to the surface of the threaded rod 2, a fixed block 6 is fixedly connected to the surface of the outer frame 1, a connecting rod 8 is fixedly connected between the sliders 5, and a night protection component is arranged between the connecting rod 8 and the outer frame 1, and the night protection component includes a connecting shaft 7 rotatably arranged inside the fixed block 6, and the surface of the connecting shaft 7 is fixedly connected to the external protective cloth by winding, and when the night protection component is working, the display screen 9 is covered by the protective cloth.

[0038] A cleaning assembly is arranged between the connecting rod 8 and the outer frame 1, and the cleaning assembly includes a brush plate 16 slidably arranged on the surface of the outer frame 1. When the cleaning assembly is working, the display screen 9 is cleaned by the brush plate 16. A jet assembly is arranged on the surface of the outer frame 1, and the jet assembly includes an air nozzle 20 fixedly connected to the surface of the outer frame 1. When the jet assembly is working, air is blown toward the display screen 9. The support plates 3 are symmetrically distributed about the center of the outer frame 1. The night protection assembly also includes a limit rod 4 fixedly connected between the support plates 3, and a slider 5 is slidably connected to the surface of the limit rod 4.

[0039] The slider 5 is symmetrically distributed about the center of the connecting rod 8, and the left surface of the connecting rod 8 is connected to the end of the protective cloth. The surface of the connecting shaft 7 is fixedly connected with a torsion spring 10 which plays an elastic reset role, and the other side of the torsion spring 10 is fixedly connected to the inner wall of the fixed block 6.

[0040] At night, the driving motor on the surface of the outer frame 1 is started, and the threaded rod 2 rotates, and then the slider 5 and the connecting rod 8 move in the horizontal direction under the action of the threaded rod 2 and the limit rod 4. At this time, the slider 5 drives the connecting rod 8 to move to the right side of the outer frame 1, and then the connecting rod 8 drives the protective cloth to unfold, so as to protect the display screen 9.

[0041] During the unfolding process of the protective cloth, the connecting shaft 7 will rotate inside the fixed block 6. When the connecting shaft 7 rotates, the torsion spring 10 will be stretched. During the day, when the display screen 9 needs to be used again, the threaded rod 2 will rotate. At this time, the slider 5 and the connecting rod 8 will move back, and then the connecting shaft 7 and the protective cloth will lose the tension. At this time, the connecting shaft 7 will rotate under the action of the torsion spring 10. When the connecting shaft 7 rotates, the protective cloth will be rolled up to facilitate the next use of the night protection component.

[0042] Embodiment 2: Different from Embodiment 1, the dust on the surface of the display screen 9 can be cleaned by the brush plate 16 by means of the cleaning component. Figure 4-Figure 7 As shown, the cleaning assembly also includes a column 13 fixedly connected to the inner wall of the connecting rod 8, and a moving block 14 is slidably connected to the surface of the column 13, and a brush plate 16 is plugged and connected to the surface of the moving block 14.

[0043] A long rod 11 is fixedly connected to the outer wall of the outer frame 1, and a protrusion 12 is fixedly connected to the upper surface of the long rod 11, and the protrusions 12 are evenly spaced on the upper surface of the long rod 11, and the left and right side surfaces of the protrusions 12 are both inclined, a force block 15 is fixedly connected to the lower surface of the moving block 14, and a first spring 17 that plays an elastic reset role is fixedly connected to the upper surface of the moving block 14, and the other side of the first spring 17 is fixedly connected to the inner wall of the connecting rod 8.

[0044] When the connecting rod 8 moves, the connecting rod 8 drives the moving block 14 and the force block 15 to move synchronously, and then the force block 15 will intermittently contact the protrusion 12. When the force block 15 is pushed by the protrusion 12, the force block 15 and the moving block 14 rise under the action of the column 13. At this time, the first spring 17 is squeezed, and when the connecting rod 8, the moving block 14 and the force block 15 continue to move, the force block 15 and the moving block 14 return to their original positions under the action of the elastic force, and the above process is repeated. The moving block 14 drives the brush plate 16 to make reciprocating linear motion in the vertical direction. At this time, the brush plate 16 can clean the dust on the surface of the display screen 9, thereby playing a self-cleaning role.

[0045] Embodiment 3: Different from Embodiment 2, the dust swept by the brush plate 16 can be blown away by the air jet nozzle 20 by means of the air jet assembly. Figure 9-11 As shown, the jet assembly includes a protection plate 19 fixedly connected to the back of the outer frame 1, and the left side view of the protection plate 19 is an inverted "L" structure, and the inner wall of the protection plate 19 is bonded with an air bag 21, the surface of the air bag 21 is fixedly connected to an air supply pipe 25, and the end of the air supply pipe 25 is fixedly connected to the jet nozzle 20, and the air supply pipe 25 is fixedly connected to the outer frame 1, the lower surface of the air bag 21 is fixedly connected to a lower connecting pipe 26, and the surface of the lower connecting pipe 26 and the surface of the air supply pipe 25 are fixedly connected to a one-way valve 27.

[0046] A cross bar 18 is fixedly connected to the back of the outer frame 1, and the end of the cross bar 18 is convex, and a working plate 22 is slidably connected to the surface of the cross bar 18, and an extrusion plate 23 corresponding to the airbag 21 is fixedly connected to the surface of the working plate 22, and a second magnet 29 is fixedly connected to the surface of the upper end slider 5, and first magnets 28 are fixedly connected to the surface of the working plate 22 at equal intervals, and the magnetic poles of the adjacent positions of the first magnet 28 and the second magnet 29 are the same, and a second spring 24 is fixedly connected to the surface of the working plate 22, and the other side of the second spring 24 is connected to the convex position of the cross bar 18.

[0047] When the slider 5 moves left and right, the slider 5 will drive the second magnet 29 to move synchronously. At this time, the second magnet 29 will intermittently approach the first magnet 28. When the second magnet 29 approaches the first magnet 28, the working plate 22 moves away from the outer frame 1 under the action of the repulsive magnetic force. At this time, the second spring 24 is squeezed, and when the second magnet 29 is away from the first magnet 28, the working plate 22 returns to its original position under the action of the second spring 24. The above process is repeated. The working plate 22 drives the squeezing plate 23 to perform reciprocating linear motion in the horizontal direction. At this time, the squeezing plate 23 will intermittently squeeze the airbag 21. When the airbag 21 is squeezed, the airbag 21 sprays air through the air supply pipe 25 and the air nozzle 20. When the air nozzle 20 sprays air, dust on the surface of the display screen 9 can be blown away. The air nozzle 20 and the brush plate 16 work together to achieve a better cleaning effect.

[0048] When the airbag 21 is not squeezed, the airbag 21 inhales air through the lower connecting pipe 26. During the process of the airbag 21 exhaling and inhaling, the one-way valve 27 directs the airflow from the lower connecting pipe 26 to the air nozzle 20, thereby ensuring the working stability of the airbag 21 and the air nozzle 20.

[0049] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
