However, the adjustment effect of the movable structure of traditional display screens is very limited. Summary of the Invention

[0043] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0044] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0045] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0046] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0048] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0049] Currently, in smart classrooms, a display screen (main controller) is installed on the podium. Teachers can interact with students' devices or control other electronic products in the classroom through the screen. To facilitate teacher use, the screen is supported by movable supports such as mounting bases or brackets. Telescopic motors and casters are installed on these supports, allowing the screen to rotate and move on the podium. However, traditional supports fail to consider that the screen protrudes too much from the podium, affecting students' viewing experience (some students' view is blocked by the screen), and that the screen often deviates from its intended position when moved. Therefore, to address the issues of traditional supports, the traditional method is to reduce the height of the support to lower the screen's installation height. However, as the support height decreases, the space for installing the telescopic motor is correspondingly reduced, requiring smaller motor models and decreasing the motor's extension range, ultimately limiting the screen's adjustable angle.

[0050] Therefore, in response to the problem that the display screen cannot be effectively rotated and moved in the classroom in traditional solutions, this application changes the structure of the stabilizing bracket equipped with the telescopic motor and the installation method of the stabilizing bracket on the moving component, thus ensuring that the display screen can be effectively rotated and moved.

[0051] Specifically, in this embodiment, a stabilizing bracket 200 is provided. The portion of the stabilizing bracket 200 protruding from the moving component 100 extends into the mounting platform 600 through the opening 610. When the moving component 100 moves the display screen, the stabilizing bracket 200 also moves within the opening 610 along the direction of movement. By limiting the sliding within the opening 610, the stabilizing bracket 200 ensures the stability of the movement of the display screen and the moving component 100. Furthermore, by installing the driving component 400 on the portion of the stabilizing bracket 200 protruding from the moving component 100, the installation space for the driving component 400 is increased. Compared to existing technologies, this allows the driving component 400 to rotate the display screen at a greater angle, thereby improving the rotation effect. Further, by improving the rotation and movement effects, the adjustment effect of the display screen is improved.

[0052] like Figures 1 to 8As shown, the teaching adjustment device includes: a mounting platform 600, a moving component 100, and a driving component 400. The mounting platform 600 has an opening 610. The moving component 100 is used to mount the display screen and can drive the display screen to move on the mounting platform 600. The moving component 100 has a stabilizing bracket 200, and the portion of the stabilizing bracket 200 protruding from the moving component 100 extends into the mounting platform 600 through the opening 610. The opening 610 extends along the moving direction of the moving component 100, and the stabilizing bracket 200 can move within the opening 610 along the moving direction. The driving component 400 is mounted on the moving component 100 through the portion of the stabilizing bracket 200 protruding from the moving component 100, and the output end of the driving component 400 is used to drive the display screen to rotate.

[0053] The aforementioned teaching adjustment device connects the display screen to the moving component 100, which in turn moves the display screen, thereby adjusting the relative position between the display screen and the presenter. An opening 610 is provided on the mounting platform 600, and a stabilizing bracket 200 is mounted on the moving component 100. The portion of the stabilizing bracket 200 protruding from the opening 610 of the moving component 100 extends into the mounting platform 600. When the moving component 100 moves the display screen, the stabilizing bracket 200 also moves along the direction of movement within the opening 610. By limiting the sliding motion of the stabilizing bracket 200 within the opening 610, the stability of the movement of the display screen and the moving component 100 is ensured. Furthermore, by providing a driving component 400, which is mounted on the portion of the stabilizing bracket 200 protruding from the moving component 100, the installation space for the driving component 400 is increased, thus increasing its range of motion. Compared to existing technologies, this allows the driving component 400 to rotate the display screen at a greater angle, thereby improving the rotation effect. Furthermore, by improving the flipping and moving effects, the adjustment effect of the display screen has been further enhanced.

[0054] Specifically, such as Figures 1 to 3 As shown, the portion of the stabilizing bracket 200 protruding from the moving component 100 slides against the extended side of the opening 610. The stabilizing bracket 200 extends into the opening 610 and abuts against the extended side of the opening 610, thereby reducing the shaking caused by the sliding of the moving component 100 and improving the sliding stability of the display screen.

[0055] More specifically, such as Figures 1 to 3 As shown, the opening 610 is a square through hole formed on the mounting platform 600, and part of the stabilizing bracket 200 extends into the mounting platform 600 through the opening 610.

[0056] It should be noted that the extended side of the opening 610 refers to the two sidewalls of the opening 610 that are perpendicular to the sliding direction.

[0057] In some embodiments, the drive element 400 is a motor. The output of the motor is connected to the display screen, and the motor can drive the display screen to rotate.

[0058] In some embodiments, the drive element 400 is a cylinder. The piston rod of the cylinder is connected to the display screen, and the cylinder can drive the display screen to rotate.

[0059] In some embodiments, the drive element 400 is a gas spring. The output end of the gas spring is connected to the display screen, enabling the gas spring to drive the display screen to rotate.

[0060] Furthermore, such as Figures 1 to 3 As shown, the stabilizing bracket 200 includes two opposing first abutment portions 210 and a first connecting portion 220. The two first abutment portions 210 are respectively connected and engaged with both ends of the first connecting portion 220, and the two first abutment portions 210 and the connecting portion enclose a receiving portion for mounting the driving component 400. The receiving portion extends out of the mounting platform 600 through the opening 610, and the two first abutment portions 210 slide against the two extended sides of the opening 610. By having the first abutment portions 210 abut against the extended sides of the opening 610, the sliding stability of the moving component 100 is improved, and the first connecting portion 220 connects the two first abutment portions 210 to form the receiving portion, which facilitates the installation of the driving component 400.

[0061] Specifically, such as Figures 1 to 3 As shown, each of the two first abutting portions 210 includes a first plate 211 and a second plate 212 arranged at an angle. Both first plates 211 are connected to the moving component 100, and both second plates 212 are connected to both ends of the first connecting portion 220 via the opening 610. The two second plates 212 and the first connecting portion 220 form a receiving portion, and the two second plates 212 slide against the two extended sides of the opening 610. The first plate 211 and the second plate 212 are arranged at an angle. The first plate 211 is connected to the moving component 100, thereby connecting the stabilizing bracket 200 and the moving component 100. The second plate 212 extends into the opening and abuts against the extended side of the opening 610, thereby reducing the shaking of the display screen during movement.

[0062] Specifically, in this embodiment, the first plate 211 and the second plate 212 are arranged vertically.

[0063] In other embodiments, the included angle between the first plate 211 and the second plate 212 is set according to actual operational needs.

[0064] Furthermore, such as Figures 1 to 3As shown, the system also includes a guide member 300, which includes two opposing second abutment portions 310 and a second connecting portion 320 connecting the two second abutment portions 310. One second abutment portion 310 is mounted and engaged with the moving component 100, while the other second abutment portion 310 and the second connecting portion 320 pass through the opening 610 and are abutted against the surface of the mounting platform 600 facing away from the moving component 100. The second connecting portion 320 of the guide member 300 extends into the opening 610, and the second abutment portions 310 are respectively used to connect to the moving component 100 and the surface of the mounting platform 600 facing away from the moving component 100, thereby fastening the guide member 300 onto the moving component 100. By providing the guide member 300, the stabilizing bracket 200 and the guide member 300 cooperate with each other to further limit the shaking during the sliding process of the display screen.

[0065] Specifically, the guide component 300 is bow-shaped.

[0066] More specifically, in this embodiment, the first plate 211, the second plate 212, the first connecting part 220, the second abutting part 310, and the second connecting part 320 are all straight plate structures.

[0067] In other embodiments, the first plate 211, the second plate 212, the first connecting portion 220, the second abutting portion 310, and the second connecting portion 320 can be of any structure, such as an arc-shaped plate.

[0068] In this embodiment, as Figures 1 to 3 As shown, the guide 300 and the stabilizing bracket 200 are two separate components.

[0069] In other embodiments, the guide 300 and the stabilizing bracket 200 are integrally formed.

[0070] In some embodiments, multiple stabilization supports 200 are provided, and all multiple stabilization supports 200 can be disposed within the opening 610; by providing multiple stabilization supports 200, the sliding stability of the moving component 100 is further improved.

[0071] In some embodiments, multiple guide members 300 are provided, and each guide member 300 can be disposed within the opening 610. By providing multiple guide members 300, the display screen is further limited in position, reducing its wobbling.

[0072] In this embodiment, as Figures 1 to 3 As shown, there is one stabilization support 200 and two guide members 300, and the two guide members 300 are arranged in a direction perpendicular to the direction of movement.

[0073] Furthermore, such as Figures 4 to 8As shown, the moving component 100 includes a sliding part 120, a mounting base 110, and a placement plate 170. The sliding part 120 is mounted on the mounting base 110, and the mounting base 110 is slidably engaged with the mounting platform 600 via the sliding part 120. The placement plate 170 is rotatably mounted on the mounting base 110 and is used to place the display screen. The mounting base 110 has a transition opening for the stability bracket 200 to pass through. The output end of the driving component 400 is mounted and engaged with the placement plate 170. By setting the placement plate 170 to support the display screen, and the mounting base 110 connected to the sliding part 120, the sliding part 120 can slide, thereby driving the mounting base 110, the placement plate 170, and the display screen to slide. The output end of the driving component 400 can pass through the transition opening and be mounted and engaged with the placement plate 170 to drive the display screen to rotate.

[0074] Specifically, such as Figure 1 As shown, a rotating shaft is provided on the mounting base 110, and hinge plates 180 are installed at both ends of the rotating shaft. The rotating shaft is connected to the placement plate 170 through the hinge plates 180. When the rotating shaft rotates, it drives the hinge plates 180 and the placement plate 170 to rotate synchronously.

[0075] In this embodiment, as Figure 1 , Figures 4 to 6 As shown, the output end of the drive unit 400 passes through the transition port and is connected to the placement plate 170. The drive unit 400 pushes the placement plate 170 to rotate, thereby causing the display screen to rotate.

[0076] Specifically, such as Figure 1 , Figures 4 to 6 As shown, the output end of the drive unit 400 is connected to the placement plate 170 via the mounting member 700. The mounting member 700 is provided at the output end of the drive unit 400, and the mounting member 700 is connected to the placement plate 170. The drive unit 400 can drive the mounting member 700 and the placement plate 170 to rotate, thereby causing the display screen to rotate.

[0077] More specifically, such as Figure 1 As shown, the mounting member 700 includes two opposing third plates 710 and a fourth plate 720 connecting the two third plates 710. The fourth plate 720 is connected to the two third plates 710 to form a mounting portion for accommodating the output end of the drive member 400. The side of the fourth plate 720 facing away from the output end of the drive member 400 is connected to the placement plate 170. By connecting the two third plates 710 with the fourth plate 720, a mounting portion is formed, and the output end of the drive member 400 extends into the mounting portion, thereby increasing the contact area between the output end of the drive member 400 and the mounting member 700, and thus increasing the thrust stability. The side of the fourth plate 720 facing away from the output end of the drive member 400 is connected to the placement plate 170. The drive member 400 pushes the mounting member 700 and the placement plate 170, thereby driving the display screen to rotate.

[0078] In some embodiments, the output end of the drive member 400 extends into the mounting portion and abuts against the inner wall of the mounting portion, thereby driving the mounting member 700 and the placement plate 170 to rotate.

[0079] In some embodiments, the output end of the drive member 400 extends into the mounting portion and is connected to the inner wall of the mounting portion. The output end of the drive member 400 extends into the mounting portion, thereby increasing the contact area between the output end of the drive member 400 and the mounting member 700. Connecting the output end of the drive member 400 to the inner wall of the mounting portion prevents the output end from falling out of the mounting portion.

[0080] More specifically, the third plate 710 and the fourth plate 720 are set vertically.

[0081] In other embodiments, the placement plate 170 is provided with an opening, and the output end of the drive unit 400 passes through the transition port and the opening in sequence to connect to the display screen.

[0082] Specifically, such as Figures 4 to 8 As shown, the sliding part 120 includes a plurality of pulleys, and at least one of the pulleys is provided with a braking structure 190. The multiple pulleys improve the sliding effect, and the braking structure 190 on at least one pulley allows the pulley to be stopped when a stop is required, thereby limiting the pulley's movement.

[0083] More specifically, such as Figure 8 As shown, a braking structure 190 is provided on at least one pulley. The braking structure 190 includes a rotating part 191 and a brake pad 192 connected to each other. The rotating part 191 is connected to the body of the pulley and can rotate, thereby causing the brake pad 192 to abut against the sliding surface of the pulley, thus braking the pulley. When the moving component 100 moves the display screen to a preset position, the rotating part 191 of the braking structure 190 is operated, causing the brake pad 192 to abut against the sliding surface of the pulley, limiting the pulley and thus restricting the movement of the moving component 100.

[0084] Specifically, such as Figures 4 to 8As shown, the movable component 100 also includes a slide rail bracket 130 and a pulley bushing 140. The pulley bushing 140 is connected to the mounting base 110, and the slide rail bracket 130 is fixed on the mounting platform 600. The slide rail bracket 130 is provided with a groove 131 extending in the moving direction, and the pulley bushing 140 slides in cooperation with the groove 131. By setting the slide rail bracket 130 and the pulley bushing 140, and providing the groove 131 extending in the moving direction on the slide rail bracket 130, the pulley bushing 140 is inserted into the groove 131 on the slide rail bracket 130. When the pulley slides in the moving direction, the pulley bushing 140 slides synchronously along the groove 131. This application guides the moving direction of the movable component 100 by setting the pulley bushing 140 to slide along the groove 131. Moreover, both the sliding part 120 and the pulley bushing 140 can slide, improving the sliding stability of the movable component 100.

[0085] Specifically, such as Figures 4 to 8 As shown, the slide rail bracket 130 includes a mating part 132 and a supporting part 133 connected to each other. The mating part 132 and the supporting part 133 are arranged at an included angle. The supporting part 133 is connected to the mounting platform 600, and the mating part 132 is provided with a sliding groove 131. By setting the supporting part 133 to be connected to the mounting platform 600, the slide rail bracket 130 is connected and fixed. The sliding groove 131 on the mating part 132 slides and engages with the pulley bushing 140 mounted on the mounting base 110.

[0086] Specifically, the mating part 132 and the supporting part 133 are arranged at an angle, with the angle between the mating part 132 and the supporting part 133 being greater than 0° and less than 180°.

[0087] In this embodiment, the included angle between the mating part 132 and the supporting part 133 is 90°, such as Figures 4 to 8 As shown, the slide rail bracket 130 is L-shaped.

[0088] In other embodiments, the included angle between the mating part 132 and the support part 133 is set according to the operational requirements, for example, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, or 170°.

[0089] The existing pulley bushing and slide groove have a single-sided contact and sliding fit structure, which leads to unstable sliding and the pulley bushing 140 is prone to derailment. To solve this problem, such as... Figures 4 to 8As shown, the slide groove 131 of this application is a closed structure, and the pulley bushing 140 is inserted into the slide groove 131 and slides in cooperation with it. By making the slide groove 131 a closed structure, this application increases the contact area between the pulley bushing 140 and the slide groove 131 when the pulley bushing 140 is inserted into the slide groove 131, which not only improves the sliding stability but also prevents the pulley bushing 140 from disengaging from the slide groove 131.

[0090] It should be noted that the above-mentioned closure refers to... Figure 5 and Figure 7 From the perspective shown, both the upper and lower end faces of the pulley bushing 140 are in contact with the groove wall of the slide groove 131.

[0091] Specifically, such as Figures 4 to 8 As shown, the pulley bushing 140 is connected to the mounting base 110 via the connecting bracket 150.

[0092] Specifically, such as Figures 4 to 8 As shown, the connecting bracket 150 is L-shaped, with one end connected to the bottom surface of the mounting base 110 and the other end connected to the pulley bushing 140.

[0093] Specifically, such as Figures 4 to 8 As shown, the moving assembly 100 also includes a limiting plate 160, which is connected to the slide rail bracket 130 and is used to limit the movement of the pulley bushing 140. By setting the limiting plate 160, the limiting plate 160 can abut against the pulley bushing 140, thereby limiting the sliding distance of the pulley bushing 140.

[0094] Specifically, multiple slide rail brackets 130 and pulley bushings 140 are provided, with each slide rail bracket 130 and pulley bushing 140 corresponding one-to-one. By providing multiple slide rail brackets 130 and pulley bushings 140 that slide in cooperation with the multiple slide rail brackets 130, the sliding stability is improved.

[0095] More specifically, such as Figures 4 to 8As shown, the sliding part 120 includes a first pulley and a second pulley arranged along a first direction; the slide rail bracket 130 includes a first slide rail bracket 130 and a second slide rail bracket 130 arranged along the first direction; the pulley bushing 140 includes a first pulley bushing 140 that slides with the first slide rail bracket and a second pulley bushing 140 that slides with the second slide rail bracket. The system is equipped with a first pulley and a second pulley, a first slide rail bracket 130 and a second slide rail bracket 130, and a first pulley bushing 140 and a second pulley bushing 140. The first slide rail bracket 130 and the first pulley bushing 140 slide with each other, and the second slide rail bracket 130 and the second pulley bushing 140 slide with each other. Both the first pulley and the second pulley are mounted on the mounting base 110. When the first pulley and the second pulley drive the mounting base 110 to move, the pulley bushing 140 slides synchronously within the corresponding slide rail bracket 130, thereby improving the sliding stability of the moving component 100.

[0096] More specifically, such as Figures 4 to 8 As shown, the slide rail bracket 130 is L-shaped, and the support portions 133 of the two slide rail brackets 130 extend in a direction away from each other.

[0097] More specifically, such as Figures 4 to 8 As shown, a braking structure 190 is provided on one of the first pulley and the second pulley.

[0098] In this embodiment, as Figures 4 to 8 As shown, the first pulley and the first slide rail bracket 130 are arranged along the moving direction, and the second pulley and the second slide rail bracket 130 are also arranged along the moving direction. The sliding part 120 and the slide rail bracket 130 are arranged along the moving direction, and a groove 131 extending along the moving direction is provided on the slide rail bracket 130. The pulley bushing 140 is embedded in the groove 131 and can slide along the groove 131. That is, the sliding part 120 and the pulley bushing 140 are arranged along the moving direction and move coaxially. Furthermore, by limiting the arrangement of the sliding part 120 and the slide rail bracket 130, the slide rail bracket 130 provides a certain degree of support for the mounting base 110, solving the problem of the base plate of the mounting base 110 being recessed due to the installation of the display screen on the placement plate 170.

[0099] More specifically, such as Figures 4 to 8 As shown, the sliding part 120 is located in front of the slide rail bracket 130, where "in front" refers to the direction in which the moving component 100 moves away from the mounting platform 600 along the moving direction. That is, the sliding part 120 is located in front of the mounting base 110, and the slide rail bracket 130 is located behind the sliding part 120. The slide rail bracket 130 provides a certain support for the mounting base 110, preventing the middle area of ​​the mounting base 110 from sinking.

[0100] In other implementations, the relative interval between the two slide rail brackets 130 is greater than the relative interval between the two pulleys. By limiting the distance between the two pulleys and the distance between the two slide rail brackets 130, the sliding traction is made smoother.

[0101] Specifically, such as Figures 1 to 8 As shown, it also includes a dust cover 500, which is connected to the mounting base 110 and the placement plate 170. The dust cover 500, the mounting base 110, and the placement plate 170 form a dustproof space. By setting the dust cover 500 to connect the mounting base 110 and the placement plate 170, the dust cover 500, the mounting base 110, and the placement plate 170 form a dustproof space, preventing external dust or water droplets from flowing into the opening 610 or flowing into the area below the mounting platform 600 through the opening 610.

[0102] This application also provides a smart lectern, such as Figure 9 As shown, the system includes a display screen and any of the aforementioned teaching adjustment devices, along with a cabinet base 800. The teaching adjustment device is mounted on the cabinet base 800. The display screen is connected to the movable component 100, and the teaching adjustment device is mounted on the cabinet base 800. By improving the flipping and moving effects, the adjustment effect of the display screen is improved.

[0103] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0104] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
