[0030] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, and circuits have been omitted so as not to obscure the description of this application with unnecessary detail.

[0031] With the popularization of information technology, more and more smart devices have emerged in various fields. For example, smart blackboards can enrich the intelligence of teaching and are widely used in various educational venues, replacing traditional blackboards. Currently, smart blackboards in related technologies are usually equipped with different display stands to meet different educational display needs, such as wired wall-mounted display stands and wireless mobile display stands. Among them, wired wall-mounted display stands are limited by connecting cables and are usually placed close to the smart blackboard, such as on the left or right sides. As a result, because the wall-mounted space on one side of the smart blackboard is occupied by the wall-mounted display stand, there is not enough space to attach paper documents such as timetables and student rules, which cannot be pasted on both sides of the smart blackboard as needed. Wireless mobile display stands offer high flexibility, allowing for handheld or fixed placement for demonstrations. To prevent loss, a dedicated space is typically needed at the podium or other location for storage. Therefore, to accommodate both wired wall-mounted and wireless mobile display stands, not only is a wall-mounted stand required on one side of the smart blackboard in the educational setting, but a separate space is also needed at the podium or other location for storage. This results in a significant space requirement for storage in educational settings, which may not be feasible when space is limited. Furthermore, when a mobile display stand is placed at the podium or other locations, there is a risk of it being knocked down and damaged, or even injuring students, posing a safety hazard.

[0032] Therefore, this application provides a wireless display stand and a smart blackboard with a wireless display stand. The wireless display stand can meet the needs of both wall-mounted and mobile display stands, making it highly practical. Furthermore, the wireless display stand and the smart blackboard are set up adjacent to each other, eliminating the need to set up an additional display stand on the podium, thus saving space.

[0033] The following description, in conjunction with the accompanying drawings, provides an exemplary description of the wireless display stand and the smart blackboard with the wireless display stand provided in this application.

[0034] like Figure 1As shown, this application embodiment provides a smart blackboard with a wireless display stand, including a wireless display stand 1 and a smart blackboard 2. The first side of the wireless display stand 1 and the smart blackboard 2 are movably connected. Here, it can be understood that the movable connection means that the positional relationship between the wireless display stand 1 and the smart blackboard 2 can be adjusted according to different needs, which is highly flexible.

[0035] For example, when the wireless display stand 1 is not needed for display, it can be moved to the first side of the smart blackboard 2. It's worth noting that the first side of the smart blackboard 2 faces the wall or fixed object, and there is a gap between the first side of the smart blackboard 2 and the wall or fixed object to accommodate the wireless display stand 1. When the wireless display stand 1 and the smart blackboard 2 completely overlap, the wireless display stand 1 is completely contained within the gap between the first side of the smart blackboard 2 and the wall or fixed object. This allows for the attachment of paper documents such as timetables and student rules to the wall-mounted spaces on both sides of the smart blackboard 2 as needed. This avoids the problem of the wall-mounted display stand occupying one side of the smart blackboard 2, resulting in insufficient space for attaching timetables, student rules, and other paper documents to the sides of the smart blackboard 2 as required.

[0036] In this example, a connecting component can be provided between the wireless display stand 1 and the smart blackboard 2 to achieve an active connection between them. The connecting component can be a slide rail, slider, chain, traction device, etc., and this application does not impose specific limitations on it. For example, taking a slide rail as the connecting component, such as... Figure 2 As shown, the first surface of the smart blackboard 2 is provided with a first slide rail 21 and a second slide rail 22. The top of the wireless display stand 1 is connected to the first slide rail 21, and the bottom of the wireless display stand 1 is connected to the second slide rail 22. A channel 2A is formed between the first slide rail 21 and the second slide rail 22 for the wireless display stand 1 to slide. The wireless display stand 1 can move along the first slide rail 21 and the second slide rail 22 to achieve a telescopic function. When the wireless display stand 1 is not needed for display, it can be moved into the channel 2A until it completely overlaps with the smart blackboard 2. That is, the wireless display stand 1 can be completely stored in the gap between the first surface of the smart blackboard 2 and the wall, leaving wall-mounted space on one side of the smart blackboard 2 for posting timetables or student rules, thereby making full use of the space in the teaching space. When the wireless display stand 1 is needed for display, it is moved out of the channel 2A until it is as shown in the image. Figure 1 The wall-mounted space on one side of the smart blackboard 2 is shown. In this case, the wireless display stand 1 and the smart blackboard 2 are positioned adjacent to each other, allowing the wireless display stand 1 to display content as needed. Thus, by setting a first slide rail 21 and a second slide rail 22 on the first surface of the smart blackboard 2, the wireless display stand 1 can move relative to the smart blackboard 2 to meet different needs for storage and display, offering high flexibility.

[0037] Optionally, for convenient mobile wireless display stand 1, such as Figure 3 As shown, a handle 13 can be provided on the side wall of the wireless display stand 1. Here, it can be understood that the side wall of the wireless display stand 1 refers to the side away from the side wall of the smart blackboard 2. By providing the handle 13, the convenience of the mobile wireless display stand 1 can be improved.

[0038] The display needs vary across different scenarios. For example, fixed displays may be required in large educational venues such as multimedia function halls, while handheld mobile displays may be necessary in smaller educational venues such as classrooms. To meet the display needs of different scenarios, the wireless display stand 1 in this application can achieve both fixed wall-mounted display and mobile display. Figure 4 As shown, in one example, the wireless display stand 1 in this application may include a stand 11 and a display stand body 12. The stand 11 is movably connected to the smart blackboard 2 to realize the storage and display of the wireless display stand 1, and the display stand body 12 is used for display according to different needs.

[0039] Optional, such as Figure 4 As shown, the stand 11 may include a stand body 111 and a tray 112 hinged to the stand body 111. It is worth noting that the stand body 111 and the tray 112 are movably hinged, meaning they are angled, and the angle can be adjusted according to different needs. The stand body 111 can be a groove-shaped structure, consisting of a bottom wall and a surrounding frame. A receiving cavity 11A is formed within the stand body 111, providing storage and display positions to meet various requirements. For example, when the main body 12 of the exhibition stand needs to be used for display, i.e., in the display state, the main body 12 of the exhibition stand can be set up according to different needs. For instance, when it needs to be used as a mobile exhibition stand, it can be held directly in hand; when it needs to be used as a fixed exhibition stand, it can be placed in the display position within the receiving cavity 11A. The stand body 111 and the tray 112 are set at an angle. At this time, the documents to be displayed can be placed on the tray 112. In this case, the tray 112 serves as a display platform, allowing the main body 12 to retrieve and display them. Thus, the main body 12 of the exhibition stand in this application is a two-in-one structure, which can be fixed in the display position within the receiving cavity 11A to meet the needs of a wall-mounted exhibition stand, and can also be held in hand to meet the needs of a mobile exhibition stand. It has strong flexibility and practicality, and there is no need to set up an additional podium or other storage device, reducing manufacturing costs and saving space.

[0040] In this example, to improve the stability of documents placed on tray 112, such as... Figure 5As shown, in the display state, the angle between the stand body 111 and the tray 112 can be 90 degrees. Thus, when the smart blackboard 2 is set perpendicular to the ground, the stand body 111 is also perpendicular to the ground, and the tray 112 is parallel to the ground. This avoids the problem that documents may slip off the tray 112 if it is tilted, thus improving the stability of documents placed on the tray 112. This ensures the reliability of the display stand body 12 in displaying documents on the tray 112 and guarantees the display effect.

[0041] Optionally, in order to improve the connection between the platform body 111 and the tray 112, the bottom of the tray 112 is hinged to the bottom of the platform body 111. The tray 112 can also be movably connected to the platform body 111 through two telescopic components to improve the connection between the platform body 111 and the tray 112. Other movable connecting parts can also be used. This application does not impose specific limitations on this.

[0042] For example, when no display is needed, i.e., in the non-display state, the main body 12 of the display stand can be stored in its storage position. That is, when no display is required, the main body 12 can be stored inside the frame 111 to prevent loss. This also prevents the main body 12 from being damaged by collisions or falling when placed on a podium or similar location, or from falling and injuring students, thus improving safety. In this case, to store the frame 11 into the gap between the first surface of the smart blackboard 2 and the wall, as follows... Figure 6 As shown, the tray 112 needs to cover the receiving cavity 11A to form a closed space. That is, at this time, the angle between the stand body 111 and the tray 112 is zero, and the edge of the stand body 111 and the tray 112 are in complete contact. Thus, in the display state, the tray 112 of the stand 11 can be used as a display tray, and in the non-display state, the stand 11 can be used as a storage structure to store the main body of the exhibition stand 12. Moreover, there is no need to set up an additional podium or other storage device, which reduces manufacturing costs and saves space.

[0043] In this example, to improve the contact stability and firmness between the frame of the stand body 111 and the tray 112, and to avoid the problem of the tray 112 falling off due to low connection firmness between it and the stand body 111 when the wireless display stand 1 is stored in the gap between the first side of the smart blackboard 2 and the wall, thus affecting the storage effect, in one example, such as Figure 3As shown, a locking member 1121 can be provided on the tray 112. The locking member 1121 is positioned corresponding to the edge of the stand body 111. That is, when the wireless display stand 1 does not need to be displayed, after the tray 112 covers the receiving cavity 11A, the tray 112 can be fixedly connected to the stand body 111 through the locking member 1121. This avoids the problem that the tray 112 may fall off due to weak adhesion between the tray 112 and the stand body 111, thus affecting the storage effect. For example, as shown... Figure 6 As shown, the locking element 1121 can be located on the top of the tray 112 or in other locations. This application does not impose any specific restrictions on this.

[0044] To facilitate separation of the tray 112 from the stand body 111 during display, in one example, such as Figure 6 As shown, a handle position 1122 may also be provided on the tray 112.

[0045] To achieve the storage and display of the main body of the exhibition stand 12 by the stand 11, in one example, such as Figure 7 As shown, the stand 11 may also include a first wall-mounted bracket 113 and a second wall-mounted bracket 114. Both the first wall-mounted bracket 113 and the second wall-mounted bracket 114 are fixed to the bottom wall of the receiving cavity 11A. The main body of the display stand 12 can be installed on either the first wall-mounted bracket 113 or the second wall-mounted bracket 114 to meet different needs. For example, when no display is required, the main body of the display stand 12 can be installed on the first wall-mounted bracket 113 at the storage position; when a fixed display is required, the main body of the display stand 12 can be installed on the second wall-mounted bracket 114 at the display position.

[0046] Optional, such as Figure 7 As shown, the display position can be located in the middle area of ​​the bottom wall of the cavity 11A, that is, the second wall-mounted bracket 114 is located in the middle area of ​​the bottom wall of the cavity 11A, so as to facilitate the display of the main body 12 of the booth in the display state; the storage position is located in the area close to the side wall of the cavity 11A, so that in the non-display state, the main body 12 of the booth can be stored sideways in the frame 11, so that the main body 12 of the booth can be completely located in the cavity 11A, avoiding the problem that the cavity 11A of the frame 11 is too large, resulting in the wireless booth 1 being too large.

[0047] To enable flexible assembly and disassembly between the main body 12 of the exhibition stand and the frame 11, such as Figure 8As shown, in one example, the main body 12 of the booth may include: a body 121 and a connecting component 122. The body 121 and the connecting component 122 are detachably connected. The connecting component 122 is also detachably connected to the first wall-mounted bracket 113 and the second wall-mounted bracket 114. In this way, the body 121 can be disassembled and assembled with the first wall-mounted bracket 113 or the second wall-mounted bracket 114 through the connecting component 122 to meet different needs.

[0048] For example, in a non-display state, such as Figure 9 As shown, the connecting component 122 is installed on the first wall-mounted bracket 113 so that the body 121 is in the storage position for storage; in the display state, as... Figure 10 As shown, the connecting component 122 is mounted on the second wall-mounted bracket 114 so that the device 121 is positioned for display. To enable the device 121 to be displayed, a camera 1211 is installed on the device 121. In the display state, the camera 1211 faces the tray 112 to display the documents and other items on the tray 112. The capture range of the camera 1211 on the device 121 can be as follows: Figure 11 As shown.

[0049] Optional, such as Figure 8 As shown, the connecting component 122 can be provided with two through holes, and fasteners are passed through the two through holes one by one to connect the connecting component 122 and the body 121. The fasteners can be pins, hand-tightening screws, bolts, etc., which provide a strong fastening effect and low cost. Moreover, when moving and displaying, the connecting component 122 and the body 121 can be separated by fasteners. That is, when holding the device, only the body 121 can be held for moving and displaying, so as to obtain a better grip.

[0050] In order to achieve a detachable connection between the connecting component 122 and the first wall-mounted bracket 113 and the second wall-mounted bracket 114, so as to achieve a detachable connection between the body 121 and the first wall-mounted bracket 113 and the second wall-mounted bracket 114, in one example, one of the first wall-mounted bracket 113 and the connecting component 122 may be provided with an opening, and the other may be provided with a limiting part; similarly, one of the second wall-mounted bracket 114 and the connecting component 122 may be provided with an opening, and the other may be provided with a limiting part.

[0051] For example, an opening can be provided on the first wall-mounted bracket 113, an opening can be provided on the second wall-mounted bracket 114, and a limiting part can be provided on the connecting assembly 122. For example, as Figure 7As shown, three first openings 113A can be provided on the first wall-mounted bracket 113. Two of the first openings 113A are symmetrically arranged at the bottom of the first wall-mounted bracket 113 to cooperate with the limiting part of the connecting component 122 to achieve a detachable connection. The remaining first opening 113A is arranged at the top of the first wall-mounted bracket 113 to accommodate the fasteners in the main body 12 of the exhibition stand to connect the body 121 and the connecting component 122, so as to avoid the problem of the fasteners causing wear to the first wall-mounted bracket 113 when the main body 12 of the exhibition stand is placed on the first wall-mounted bracket 113.

[0052] For example, such as Figure 7 As shown, three second openings 114A can be provided on the second wall-mounted bracket 114. Two of the second openings 114A are symmetrically arranged at the bottom of the second wall-mounted bracket 114 to cooperate with the limiting part of the connecting component 122 to achieve a detachable connection. The remaining second opening 114A is located at the top of the second wall-mounted bracket 114 to accommodate the fasteners in the booth body 12 used to connect the body 121 and the connecting component 122, so as to avoid the problem of wear on the second wall-mounted bracket 114 caused by the fasteners when the booth body 12 is placed on the second wall-mounted bracket 114. It is worth noting that, in order to reduce manufacturing costs, the first wall-mounted bracket 113 and the second wall-mounted bracket 114 can have the same structure.

[0053] The connecting component 122 has a limiting portion on the side facing the first wall mount bracket 113, for example, such as... Figure 8 As shown, the limiting part can be a hook 1221, and the connecting component 122 can be provided with two hooks 1221. The two hooks 1221 are symmetrically arranged at the bottom of the connecting component 122, so that when installed on the first wall-mounted bracket 113, the two hooks 1221 extend into the two first openings 113A at the bottom of the first wall-mounted bracket 113, thereby connecting the connecting component 122 and the first wall-mounted bracket 113. Alternatively, when installed on the second wall-mounted bracket 114, the two hooks 1221 extend into the two second openings 114A at the bottom of the second wall-mounted bracket 114, thereby connecting the connecting component 122 and the second wall-mounted bracket 114. Disassembly is convenient when moving and displaying the device.

[0054] To further improve the stability of the connecting component 122 when it is installed on the first wall-mounted bracket 113 or the second wall-mounted bracket 114, at least one hook 1221 may be provided at the top of the connecting component 122. The top of the first wall-mounted bracket 113 and the second wall-mounted bracket 114 may be hollow structures, so that when the connecting component 122 is installed on the first wall-mounted bracket 113 or the second wall-mounted bracket 114, the hook 1221 provided at the top of the connecting component 122 abuts against the side wall of the hollow structure at the top of the first wall-mounted bracket 113 or the second wall-mounted bracket 114, thereby further improving the stability of the connecting component 122 when it is installed on the first wall-mounted bracket 113 or the second wall-mounted bracket 114. It is worth noting that the number of hooks 1221 provided at the top of the connecting component 122 can be set according to actual needs. For example, if it is desired to further improve the firmness of the connecting component 122 installed on the first wall-mounted bracket 113 or the second wall-mounted bracket 114, multiple hooks 1221 can be provided side by side. If it is desired to reduce manufacturing costs, only one hook 1221 can be provided. This application does not impose specific restrictions on this.

[0055] In summary, the wireless display stand 1 provided in this embodiment has a two-in-one structure, which can be fixed in the display position within the receiving cavity 11A to meet the needs of a wall-mounted display stand, and can also be handheld to meet the needs of a mobile display stand. It offers strong flexibility and practicality, and eliminates the need for an additional podium or other storage devices, reducing manufacturing costs and saving space. Furthermore, in the non-display state, the wireless display stand 1 can be stored in the gap between the first surface of the smart blackboard 2 and the wall, leaving wall-mounting space on one side of the smart blackboard 2 for posting timetables or student rules, thereby fully utilizing the space in the teaching environment.

[0056] To prevent the main body of the booth 12 from being lost while placed in the frame 11, in one example, such as Figure 12 As shown, a locking structure 23 can be provided on the side wall of the smart blackboard 2. When the wireless display stand 1 completely overlaps with the first surface of the smart blackboard 2 through the channel 2A, the side wall of the smart blackboard 2 is flush with the side wall of the wireless display stand 1. At this time, the wireless display stand 1 can be fixed to the first surface of the smart blackboard 2 by the locking structure 23, so as to achieve storage stability and avoid the problem of the display stand body 12 being lost when placed in the frame 11.

[0057] Optionally, the locking structure 23 can be a burglarproof lock, a combination lock, or other similar structure. This application does not impose specific restrictions on this.

[0058] In one example, a baffle 24 can also be provided on the side wall of the smart blackboard 2. When the wireless display stand 1 completely overlaps with the first surface of the smart blackboard 2 through the channel 2A, the baffle 24 is located on the upper side of the wireless display stand 1 and is flush with the side wall of the wireless display stand 1.
