[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0020] Embodiment 1, refer to Figure 1-Figure 11 A smart blackboard with systematic functions includes a mounting frame 1, a motor 5 is connected to the mounting frame 1, and protective frames 2 are arranged on both sides of the mounting frame 1, and also includes: The air blowing component 3 is connected to the mounting frame 1 and is used for cleaning dust; Display component 4, which is located inside the mounting frame 1 and is used to adjust the use angle; The optimization component 6 is connected to the display component 4 and is used to improve the use effect of the display component 4.

[0021] Furthermore, one end of the mounting frame 1 is fixedly connected to the motor 5, a placement groove 104 is provided on the inner wall of the mounting frame 1, mounting grooves 103 are provided at both ends of the mounting frame 1, a through hole 102 is provided on the inner wall of one end of the mounting groove 103, the inner wall of the mounting groove 103 is fixedly connected to the protective frame 2, and a plurality of fans 7 distributed in a linear array are provided on the inner side of the protective frame 2; a guide groove 101 is provided on the inner wall of the mounting frame 1, and the guide groove 101 is arranged in an arc shape; two groups of symmetrically distributed heat-conducting tubes 105 are fixedly connected to the inner wall of the mounting frame 1, each group of heat-conducting tubes 105 is provided with a plurality of heat-conducting tubes 105, and the plurality of heat-conducting tubes 105 are distributed in a linear array; a plurality of grooves 106 corresponding to the heat-conducting tubes 105 are provided on the inner wall of the mounting frame 1, and one end of the heat-conducting tube 105 is connected to the opening of the groove 106; a plurality of heat-dissipating plates 45 corresponding to the heat-conducting tubes 105 are fixedly connected to the side wall of the display board 41, and the heat-dissipating plates 45 and the heat-conducting tubes 105 are slidably connected.

[0022] Normal heat dissipation of the display assembly 4 by the mounting frame 1: During the normal use of the display board 41, the heat generated by the display board 41 can be transferred to the gap between the display board 41 and the mounting frame 1 through the heat sink 45, and the generated heat is taken away by the normal flow of air to ensure the normal heat dissipation of the display board 41. In addition, a temperature sensor is provided inside the display board 41, and the temperature sensor is electrically connected to the fan 7. When the display board 41 is overheated, the normal air circulation cannot effectively achieve the cooling effect, and this process will cause the detection value of the temperature sensor to reach When the temperature reaches the preset value, the fan 7 is triggered to start. At this time, the fan 7 extracts the heat inside the gap and blows it to the outside of the mounting frame 1 through the protective frame 2, so as to increase the air circulation rate and avoid continuous accumulation of heat, thereby ensuring the cooling and heat dissipation effect of the display board 41, and avoiding damage to the internal components of the display board 41 caused by excessive temperature. The protective frame 2 can adopt the filtering equipment in the prior art, which can effectively prevent external dust from entering the interior of the mounting frame 1 while realizing air flow, and reduce the adhesion of dust on the back of the display board 41, so as to ensure the heat dissipation effect of the display board 41 itself.

[0023] Reference Figure 2-Figure 9 , further; the display assembly 4 includes a display board 41, and two display boards 41 are provided. The two display boards 41 are symmetrically distributed about the center line of the mounting frame 1, one end of the display board 41 is fixedly connected to a sliding rod 42, and the other end of the display board 41 is fixedly connected to a rotating rod 43, the sliding rod 42 is slidably connected to the inner wall of the guide groove 101, and the rotating rod 43 is rotatably connected to the inner wall of the mounting frame 1; the outer wall of the rotating rod 43 is fixedly connected to a gear plate 44, the gear plate 44 is located inside the placement groove 104, and the two gear plates 44 are meshed and connected, and one end of one of the rotating rods 43 passes through the inner wall of the placement groove 104 and is fixedly connected to the motor 5.

[0024] The motor 5 adjusts the angle of the display board 41: the display board 41 as a whole is composed of a whole or multiple smart screens. When the screen of the display board 41 is reflective, the motor 5 can be started by connecting the electric signal between the external remote control or the control system of the display board 41 itself and the motor 5, so that one of the display boards 41 rotates with the corresponding rotating rod 43 as the axis. At this time, through the meshing connection between the two gear plates 44, the other display board 41 can be synchronously driven to rotate with another set of rotating rods 43 as the axis, and the sliding connection between the slide bar 42 and the guide groove 101 is cooperated to achieve the synchronous angle adjustment of the two display boards 41, thereby reducing or avoiding the occurrence of reflection. For people sitting on the two sides or the back row in the classroom or conference room, by adjusting the angles of the two sides of the display board 41, the direction of the light reflected from the surface of the display board 41 can be changed, reducing the visual blind spot caused by the reflection of the display board 41, so that the viewer can see the content on the display board 41 more clearly; In addition, after adjustment, the space between the display board 41 and the mounting frame 1 is increased. Meanwhile, during the adjustment process, the sliding connection between the heat sink 45 and the heat-conducting tube 105 can drive a part of the heat sink 45 to extend out of the heat-conducting tube 105, thereby increasing the overall heat dissipation area, improving the heat dissipation effect of the display board 41 itself, promoting air circulation, and helping the display board 41 to dissipate heat better, thereby ensuring the stable operation of the equipment and extending the service life of the equipment. In addition, the use of the fan 7 can be effectively reduced or avoided, thereby saving resources and reducing the use cost. The heat sink 45 and the heat-conducting tube 105 can be made of materials with good thermal conductivity, such as copper, aluminum, etc., to promote the heat dissipation effect. In addition, Fig.12As shown, the display board 41 is provided with an Internet of Things central control processing module, which is electrically connected to a power supply module, a data acquisition module and a heat dissipation module. The power supply module is used to supply power to the live components of the entire device, and the data acquisition module can receive external remote control signals, thereby feeding back to the Internet of Things central control processing module for processing and analysis, while the heat dissipation module controls the start and stop of the fan 7 according to the specific signal. In addition, the Internet of Things central control processing module is also electrically connected to an interactive processing module, an instruction module, an external device management module, a system management module and a function expansion module. The interactive processing module is used to process touch / pressure pen input, generate handwriting data, and support gesture operation; the instruction module can receive external voice commands and convert them into executable system operations; the external device management module is used to manage external devices, such as U disks, cameras, etc., to realize resource loading and signal input; the system management module monitors the device status, such as temperature, power, etc., and cooperates with the heat dissipation module to control the heat dissipation effect, manage authority and data security; the function expansion module can be connected to an external VR device to realize three-dimensional content rendering and immersive teaching. Through the combination of multiple modules, the display board 41 reflects systematic functions and increases the intelligence of the blackboard.

[0025] Further; the optimization component 6 includes a light shield 61, and two light shields 61 are provided. The two light shields 61 are respectively fixedly connected to the side walls of one end of the two display boards 41, and the two light shields 61 are symmetrically distributed about the center line of the mounting frame 1, and a lamp tube 63 is provided inside the light shield 61; the light shield 61 is internally rotatably connected to a support frame 65, and the support frame 65 is located on the outside of the lamp tube 63, and the side walls of the support frame 65 are respectively fixedly connected with a protective cover 1 62 and a protective cover 2 64, and the protective cover 1 62 and the protective cover 2 64 are arranged in an arc shape, and the protective cover 1 62 and the protective cover 2 64 are symmetrically distributed about the center line of the support frame 65, and a knob 66 ​​is provided at one end of the light shield 61, and one end of the knob 66 ​​passes through the side wall of the light shield 61 and is fixedly connected to the side wall of the support frame 65.

[0026] Treatment of the display board 41 by the optimization component 6: During the use of the display board 41, not only can the angle be adjusted to avoid reflection, but also the lamp tube 63 in the optimization component 6 can be turned on. The lamp tube 63 can be an incandescent lamp, and the protective cover 1 62 and the protective cover 2 64 can protect the lamp tube 63 to avoid damage to the lamp tube 63 caused by external collision. In addition, the protective cover 1 62 is made of transparent material, which can protect the lamp tube 63 while ensuring the normal emission of the light of the lamp tube 63. Through the light irradiated parallel to the surface of the display board 41, the reflection of the blackboard surface can be reduced, and the shadow of the teacher when explaining can be effectively reduced, thereby improving the teaching efficiency; The protective cover 2 64 can be made of warm yellow light-transmitting materials, such as polycarbonate, acrylic, etc., and the light emitted by the general screen is cold white. The warm yellow light can complement the cold white light in terms of color tone. When the warm yellow side light is irradiated, its light mixes with the reflected light from the screen, which can neutralize the strong light reflected from the screen to a certain extent, making the reflected light less glaring, thereby reducing the interference of reflection on vision. In addition, the color temperature of warm yellow light is usually low, and the light with low color temperature is relatively softer and warmer. It does not have strong directness and high brightness contrast like the high color temperature cold white light, which makes it not produce overly strong mirror effect when it is irradiated on the screen. Surface reflection can effectively reduce the intensity of reflection. At the same time, the human eye has good adaptability and comfort to warm yellow light. In a warm yellow light environment, the human eye is not easy to produce fatigue and discomfort. Even if the screen has a small amount of reflection, due to the soft characteristics of warm yellow light, the human eye is more likely to accept and adapt, and will not make people feel obvious discomfort like reflection under other colors of light. The setting of knob 66 ​​is to adjust protective cover 1 62 and protective cover 2 64. Knob 66 ​​can be rotated according to specific usage conditions to obtain different lighting usage requirements, and it can also be used in conjunction with the angle adjustment of display board 41 to further avoid the impact caused by reflection.

[0027] Example 2, refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 , further; the blowing assembly 3 includes a baffle 31, two baffles 31 are provided, the two baffles 31 are symmetrically distributed on both sides of the mounting frame 1, the baffle 31 is fixedly connected to the mounting frame 1, and a drainage groove 32 is provided on the side wall of the baffle 31, and the drainage groove 32 is arranged in a "T" shape; a fillet 33 is provided at one end corner of the drainage groove 32, and a plurality of blowing grooves 34 distributed in a linear array are provided on the inner wall of the drainage groove 32, and the blowing groove 34 is arranged in a parallelogram shape, and the blowing groove 34 is located on one side of the fillet 33, and one end of the drainage groove 32 is connected to the through hole 102.

[0028] The cleaning of the display component 4 by the air blowing component 3: during the operation of the fan 7, part of the air is discharged to the outside through the protective frame 2, while the other part of the air enters the inside of the through hole 102 through the obstruction of the protective frame 2, and then diffuses into the inside of the drainage groove 32. With the continuous flow of air, it can be discharged from the air blowing groove 34. The air blowing groove 34 is set in the shape of a parallelogram in order to better utilize the air when it is discharged. The air is blown to the surface of the display board 41 through the inclined surface of the air blowing groove 34, so as to achieve the cleaning of the dust on the surface of the display board 41. The setting of the rounded corner 33 is to better guide the flow of air, so that when the air enters the drainage groove 32, it can quickly pass through the guiding action of the rounded corner 33. It can be used to discharge it to improve the cleaning effect and enhance the heat dissipation efficiency. In addition, when the temperature of the display board 41 rises, the migration speed of the charge on the surface of the object will be accelerated, and the static electricity will be more easily dissipated. The surface of the blackboard usually generates static electricity due to friction and other reasons, and static electricity will attract dust. When the temperature rises, the static electricity on the surface of the blackboard decreases, and the adsorption capacity of dust will decrease. Dust is not easy to be adsorbed on the surface of the blackboard. The temperature increase may make the dust particles drier and fluffier, and the adhesion between the dry and fluffy dust particles will decrease, and the adhesion to the surface of the blackboard may also decrease, so that it is not easy to be adsorbed on the blackboard. At this time, combined with the flow of air, the cleaning effect can be effectively improved, the adhesion of dust can be reduced, and the viewing clarity can be improved.

[0029] It should be noted that the specific model specifications of the motor and fan need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
