[0032] The "range" disclosed in this application is defined by a lower limit and an upper limit. A given range is defined by selecting a lower limit and an upper limit, which define the boundaries of a specific range. Ranges defined in this way include endpoint values ​​and can be arbitrarily combined; that is, any lower limit can be combined with any upper limit to form a range. For example, if ranges of 60-120 and 80-110 are listed for a specific parameter, it is also expected that ranges of 60-110 and 80-120 are also included. Furthermore, if the minimum range values ​​are listed as 1 and 2, and the maximum range values ​​are listed as 3, 4, and 5, then the following ranges are all expected: 1-3, 1-4, 1-5, 2-3, 2-4, and 2-5. In this application, unless otherwise stated, the numerical range "ab" represents a shortened representation of any combination of real numbers between a and b, where a and b are real numbers. For example, the numerical range "0-5" means that all real numbers between "0-5" have been listed herein; "0-5" is simply a shortened representation of these numerical combinations. Furthermore, when a parameter is described as an integer greater than or equal to 2, it is equivalent to disclosing that the parameter is, for example, an integer such as 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, etc.

[0039] The blackboard is the most traditional and widely used teaching medium in the classroom, an indispensable piece of educational equipment. It is reusable, inexpensive, and meets the needs of teachers to disseminate educational information to students in a class setting. With the continuous development of information technology, the term "blackboard" has been enriched and perfected, gradually becoming a general term for presentation-type teaching media, and its form has undergone tremendous changes. It has evolved from the initial simple wooden blackboard painted black, to multimedia projection systems supported by slide projection technology, and finally to interactive electronic blackboards containing basic components such as electronic screens, computers, and projection equipment.

[0040] In current electronic interactive blackboards, the main screen (hereinafter referred to as the main screen) is usually an 86-inch or 98-inch large screen, which is also quite heavy and is installed flush against the wall. During assembly, the main screen is usually fixed to the wall first using a wall-mounted bracket, and then the sub-board (also called the sub-screen) is fixed to the main screen. Figure 1 This is a partial structural diagram of an electronic interactive blackboard according to an embodiment of the related technology, such as... Figure 1 As shown, most current main screens and sub-boards are connected via a buckle system, which cannot achieve stepless adjustment. Due to the influence of the corner dimensions and assembly tolerances of the main screen, as well as the dimensional tolerances and assembly tolerances of the sub-board connectors, especially since there is no positioning structure during the assembly of the sub-board connectors (the main body of the sub-board is a honeycomb aluminum plate, which cannot be positioned), the differences are significant each time. This can cause the tightness of the locking structure to be found to be insufficient after fastening, requiring repeated adjustments after fastening, which causes a lot of inconvenience to the installation workers.

[0041] In view of this, the present application provides an electronic interactive blackboard, which includes a first main body and a second main body; a connecting component, including a first connecting component and a second connecting component, the second connecting component including a first sub-component and a second sub-component, the first connecting component being connected to the first main body, the first sub-component being connected to the first connecting component, and the second sub-component being connected to the second main body; the first sub-component includes a threaded sleeve structure that mates with the threaded structure of the first connecting component, the second sub-component includes a third connecting component, a sliding part, and a support structure, the sliding part being located between the third connecting component and the support structure, and the support structure being used to connect the second main body; the third connecting component is used to connect to the first sub-component, and the sliding part is used to provide sliding space for the first sub-component. In the technical solution of this application, the first main body and the second main body are connected by threads, which can easily realize the connection between different components of the electronic interactive blackboard and achieve the effect of stepless adjustment.

[0042] The electronic interactive blackboard described in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0043] Figure 2This is a schematic diagram of the structure of an electronic interactive blackboard according to one embodiment of this application. Figure 2 As shown, the electronic interactive blackboard 10 includes a first main body 20 and a second main body 30.

[0044] In some embodiments, the first main body 20 can be the main screen of the electronic interactive blackboard 10, and the second main body 30 can be the sub-board of the electronic interactive blackboard 10; in other embodiments, the first main body 20 can also be the sub-board of the electronic interactive blackboard 10, and the second main body 30 can also be the main screen of the electronic interactive blackboard 10.

[0045] In some embodiments, the first main body 20 is the main screen 20, and the second main body 30 is the sub-board 30.

[0046] In some implementations, the secondary board 30 is located on both sides of the main screen 20.

[0047] The main screen 20 is the core component of the electronic interactive blackboard 10, primarily responsible for processing and controlling its main functions. It typically integrates key hardware such as a processor, memory, and storage, runs an operating system and various teaching software, and performs functions such as processing touch signals, controlling signal display, and communicating with external devices. For example, when a user performs touch operations on the electronic interactive blackboard 10, the main screen 20 receives and analyzes the signals, and then executes corresponding actions according to the operation instructions, such as opening applications, writing on the blackboard, or playing multimedia content.

[0048] The secondary board 30 primarily serves as an auxiliary component to the main screen 20, providing additional functions or expansion interfaces. For example, the secondary board 30 may be equipped with commonly used shortcut keys for quickly performing functions such as opening the whiteboard software, saving whiteboard notes, scrolling up and down the page, changing pen colors, switching between software and desktop, and writing with chalk. Furthermore, the secondary board 30 may also be used to connect external devices, such as document scanners or infrared remote control receivers, to expand the functionality of the whiteboard.

[0049] The main screen 20 is usually located in the middle of the electronic interactive blackboard 10 and is the main display area of ​​the electronic interactive blackboard 10. It is relatively large in size. The secondary screen 30 is located on both sides of the main screen 20 and is relatively small in size.

[0050] Figure 3 for Figure 2 A magnified view of a portion of region A in the middle. Figure 4 This is a schematic diagram of the structure of the connecting component according to one embodiment of this application. Figure 5 This is a schematic diagram of the structure of the connecting component according to another embodiment of this application. Figure 6 This is a schematic diagram of the structure of the second connecting member according to an embodiment of this application. Figure 3-6As shown, the connecting component 40 includes a first connecting component 50 and a second connecting component 60. The second connecting component 60 includes a first sub-component 610 and a second sub-component 620. The first connecting component 50 is connected to the first main body 20, the first sub-component 610 is connected to the first connecting component 50, and the second sub-component 620 is connected to the second main body 30.

[0051] In other words, the first connecting component 50 is connected to the main screen 20, and the second connecting component 60 is connected to the sub-board 30.

[0052] Figure 3 The diagram shows the connection between the main screen 20 and the secondary board 30 achieved through the connecting component 40. Figure 4 The image shows the connection state between the first connecting component 50 and the second connecting component 60. Figure 5 The image shows the first connecting part 50 and the second connecting part 60 in a separated state. Figure 6 The image shows the first sub-component 610 and the second sub-component 620 in their separated state.

[0053] The first connecting component 50 includes a threaded structure, the first sub-component 610 includes a threaded sleeve structure that mates with the threaded structure of the first connecting component 50, and the second sub-component 620 includes a third connecting component 621, a sliding part 622, and a support structure 623. The sliding part 622 is located between the third connecting component 621 and the support structure 623. The support structure 623 is used to support the second sub-component 620 and connects to the second main body 30. The third connecting component 621 is used to connect with the first sub-component 610, and the sliding part 622 is used to provide sliding space for the first sub-component 610.

[0054] In the connected state of the electronic interactive blackboard 10, the first connecting component 50 is connected to the main screen 20, and the second connecting component 60 is connected to the sub-board 30. The second connecting component 60 includes a first sub-component 610 and a second sub-component 620. The threaded sleeve structure of the first sub-component 610 connects with the threaded structure of the first connecting component 50. That is, the connection sequence between the main screen 20 and the sub-board 30 via the connecting component 40 is: main screen 20, first connecting component 50, first sub-component 610, second sub-component 620, and sub-board 30.

[0055] The bracket structure 623 provides support for the second sub-component 620, and the bracket structure 623 can be used to connect the second connecting component 60 and the sub-plate 30.

[0056] like Figure 6As shown, when a sliding part 622 is provided between the elastic member 621 and the support structure 623, the transition from the assembly process to the locking process of the first connecting member 50, the first sub-member 610, and the second sub-member 620 can be realized. Specifically, before the second connecting member 60 is connected to the first connecting member 50 as a whole, the first sub-member 610 can first be connected to the second sub-member 620, and then slide on the sliding part 622 to contact the first connecting member 50, and then drag the entire second connecting member 60 to connect with the first connecting member 50. Therefore, when the first sub-member 610 is first connected and fixed to the second sub-member 620 and then connected to the first connecting member 50, the first sub-member 610 can slide on the sliding part 622, which can reduce the difficulty of connecting the first connecting member 50 and the first sub-member 610, so as to achieve a better connection state between the first connecting member 50 and the second connecting member 60.

[0057] In the above scheme, the first connecting component 50 is connected to the main screen 20, and the second connecting component 60 is connected to the sub-board; furthermore, the first sub-component 610 of the first connecting component 50 and the second connecting component 60 are connected by threads to realize the connection between the main screen 20 and the sub-board 30. In this way, the connection between the main screen 20 and the sub-board 30 of the electronic interactive blackboard 10 can be easily realized, achieving the effect of stepless adjustment.

[0058] It should be noted that this application does not have a particular limitation on the length of the sliding part 622, which can be modified according to the actual needs of the product. For example, it can be 1mm, 5mm, 10mm, etc.

[0059] In some embodiments, the third connecting member 621 includes an elastic member 621 that is embedded in the first sub-member 610 to achieve the connection between the first sub-member 610 and the second sub-member 620.

[0060] Specifically, an elastic member 621 is used as an intermediate medium to connect the first sub-component 610 and the second sub-component 620. The elastic member 621 is deformable and can return to its original shape. It generates a restoring force through its own elasticity. When it is inserted into the first sub-component 610, the elastic member 621 opens, thereby realizing the connection between the first sub-component 610 and the second sub-component 620.

[0061] In the above scheme, the third connecting component 621 is an elastic component 621. The elastic component 621 is inserted into the first sub-component 610 so that when the first sub-component 610 and the second sub-component 620 are connected, there is no need for precise thread matching, which can accommodate certain dimensional errors. The elastic component 621 also has a certain buffering capacity, which can reduce the damage to the first sub-component 610 (threaded sleeve structure 610) or other components caused by rigid impact. Furthermore, the assembly and disassembly of the elastic component 621 are quicker.

[0062] It should be noted that the elastic component 621 here can be a spring or other elastic metal, or a rubber ring or silicone pad or other elastic non-metal. This application does not limit the type of component.

[0063] Please continue to refer to Figure 5 and Figure 6 In some embodiments, the first sub-component 610 includes a first end 613 away from the first connecting member 50 and a second end 614 close to the first connecting member 50; the outer diameter of the elastic member 621 is larger than the inner diameter of the first end 613, and the inner diameter of the second end 614 is larger than the inner diameter of the first end 613.

[0064] The first sub-component 610 includes a first end 613 and a second end 614. Specifically, the first end 613 is connected to the elastic member 621, and the second end 614 is connected to the first connecting member 50.

[0065] The elastic component 621 is embedded in the first sub-component 610, and the outer diameter of the elastic component 621 is larger than the inner diameter of the first end 613. This is a mechanical structure design that uses an interference fit and elastic deformation to achieve a fast connection. Its core is to generate continuous radial pressure through the "size difference" of the elastic component 621 to ensure that the elastic component 621 and the first end 613610 of the threaded sleeve structure 610 are tightly connected.

[0066] In the above solution, by making the outer diameter of the elastic component 621 larger than the inner diameter of the first end 613, a more secure connection can be achieved between the first sub-component 610 and the second sub-component 620, which can take into account both tightness, cushioning and assembly flexibility.

[0067] It should be noted here that the outer diameter of the elastic component 621 refers to the outer diameter of the elastic component 621 at its largest size in its natural state.

[0068] In some embodiments, the difference between the outer diameter of the elastic member 621 and the inner diameter of the first end 613 is greater than or equal to 1 mm.

[0069] Specifically, the difference between the outer diameter of the elastic member 621 and the inner diameter of the first end 613 can be 1mm, 1.1mm, 1.3mm, 1.5mm, 1.6mm, 1.8mm, 2mm, 2.5mm, 3mm or any value within the above range.

[0070] It should be noted that the difference between the outer diameter of the elastic component 621 and the inner diameter of the first end 613 should be flexibly changed according to the elastic force of the elastic component 621, the required firmness of the first sub-component 610 and the second sub-component 620, and the external dimensions of the electronic interactive blackboard 10.

[0071] Figure 7 and Figure 8 This is a schematic diagram of the connecting component according to another embodiment of this application. Wherein, Figure 7 This indicates that the first connecting part 50 is not locked to the second connecting part 60. Figure 8 This indicates the locked state of the first connecting member 50 and the second connecting member 60. In some embodiments, the first sub-component 610 includes a first end 613 away from the first connecting member 50 and a second end 614 close to the first connecting member 50, and the third connecting member 621 includes a limiting portion 6241. The first end 613 is located between the support structure 623 and the limiting portion 6241. When the first sub-component 610 is locked with the first connecting member 50, the limiting portion 6241 abuts against the first end 613.

[0072] In some embodiments, the second sub-component 620 further includes a fourth connecting component 624, which is located on the side of the sliding portion 622 away from the support structure 623, and the third connecting component 621 is threadedly connected to the fourth connecting component 624.

[0073] like Figure 7 As shown, when the first sub-component 610 is first connected to the second sub-component 620 but not tightly connected to the first connecting component 50, the first end 613 of the first sub-component 610 can slide on the sliding part 622. At this time, the fourth connecting component 624 and the third connecting component 621 are threadedly connected.

[0074] like Figure 8 As shown, when the first sub-component 610 is tightly connected to the first connecting component 50, the first end 613 of the first sub-component 610 abuts against the limiting part 6241, and at this time the fourth connecting component 624 is located inside the first sub-component 610.

[0075] That is, when the first sub-component 610 and the second sub-component 620 are connected by elastic force, the second sub-component 620 includes an elastic member 621; when the first sub-component 610 and the second sub-component 620 are connected by threads, the second sub-component 620 includes a fourth connecting member 624.

[0076] It should be noted that this application does not limit the assembly process of the second sub-component 620. For example, the third connecting component 621, the sliding part 622, and the support structure 623 in the second sub-component 620 can be an integrally formed structure or a structure to be assembled later. When it is a structure to be assembled later, the third connecting component 621 can be inserted into the first sub-component 610 first, and then the third connecting component 621, the sliding part 622, and the support structure 623 can be assembled in sequence. Of course, it can also be flexibly adjusted according to the specific manufacturing process.

[0077] It should be noted that the limiting part 6241 only needs to abut against the first end 613 to achieve the locking function when the first sub-part 610 is locked with the first connecting part 50. It can be provided on the third connecting part 621, the fourth connecting part 624, or the sliding part 622.

[0078] Please continue to refer to Figure 6 .like Figure 6 As shown, the outer surface of the first sub-component 610 is provided with a protrusion 611 and a recess 612 extending along the axial direction of the first sub-component 610, and the protrusion 611 and the recess 612 are alternately arranged.

[0079] The axial direction of the first sub-component 610 refers to the direction parallel to the central axis of the first sub-component 610. Here, the first sub-component 610, which is the threaded sleeve structure 610, can be considered as a hollow cylinder (or approximately a cylinder) with an imaginary straight line running through its center (passing through the center points of both end faces of the threaded sleeve structure 610). This straight line is the "axis line" of the threaded sleeve structure 610. The "axial direction" is the direction along this axis, simply put, it is the length direction of the threaded sleeve structure 610 (the direction extending from one end of the threaded sleeve structure 610 to the other end).

[0080] In the above scheme, by providing alternating protrusions 611 and recesses 612 on the outer surface of the first sub-component 610 of the threaded sleeve structure, the friction of the threaded sleeve structure 610 can be increased, making it easier to rotate the first sub-component 610.

[0081] It should be noted that, in addition to setting alternating protrusions 611 and recesses 612 to increase the friction of the first sub-component 610, a rubber ring or other material with high friction can also be set on the surface of the first sub-component 610.

[0082] In some embodiments, the first connecting component 50 is threaded or slidably connected to the main screen 20; the second connecting component 60 is threaded or slidably connected to the sub-plate 30.

[0083] That is, the first connecting component 50 and the main screen 20 can be connected by a thread or a sliding connection, and the second connecting component 60 and the sub-board 30 can be connected by a thread or a sliding connection.

[0084] In some embodiments, when the first connecting component 50 is threadedly connected to the main screen 20, the second connecting component 60 is slidably connected to the sub-board 30; when the first connecting component 50 is slidably connected to the main screen 20, the second connecting component 60 is slidably connected to the sub-board 30.

[0085] That is, the connection method between the first connecting component 50 and the main screen 20 can be different from the connection method between the second connecting component 60 and the sub-board 30, so as to balance the connection strength and convenience of the electronic interactive blackboard 10.

[0086] In some embodiments, when the first connecting component 50 is slidably connected to the main screen 20, one of the first connecting component 50 and the main screen 20 is provided with a T-shaped slider, and the other is provided with a convex groove.

[0087] In some embodiments, when the second connecting member 60 is slidably connected to the sub-plate 30, one of the second connecting member 60 and the sub-plate 30 is provided with a T-shaped slider 70, and the other is provided with a convex groove 80.

[0088] The cross-section of the T-shaped slider 70 is T-shaped, consisting of a vertical rod and a horizontal head. The vertical rod is a vertical rod-like structure, with one end connected to an external component (such as a worktable or actuator), and is the main body for transmitting motion and force. The horizontal head is a horizontal "cap-like" structure at the bottom of the vertical rod, wider than the vertical rod, used to lock into the convex groove 80 to prevent the T-shaped slider 70 from disengaging in a direction perpendicular to the direction of motion.

[0089] The convex groove 80 is a "groove-shaped channel" fixed on the base (such as the frame or guide rail base). Its cross-section is convex and it is the "motion track" of the T-shaped slider 70.

[0090] The top of the T-shaped slider 70 has a transverse flange, and the inner side of the groove of the convex groove 80 has a raised step. The T-shaped flange is embedded in the convex step to form a mechanical constraint, which ensures that the T-shaped slider 70 slides along the length of the convex groove 80 and prevents the T-shaped slider 70 from coming out of the groove.

[0091] When using a sliding connection, the sliding connection is achieved by the combination of the T-shaped slider 70 and the convex groove 80.

[0092] In some embodiments, the T-shaped slider 70 and the convex groove 80 are detachably connected.

[0093] Figure 9 This is a partial structural diagram of an electronic interactive blackboard according to one embodiment of this application. Figure 9 As shown, in this embodiment, the first connecting component 50 is connected to the main screen 20 by a thread, and the second connecting component 60 is slidably connected to the sub-plate 30. The second connecting component 60 is provided with a T-shaped slider 70, and the sub-plate 30 is provided with a convex groove 80.

[0094] In some embodiments, there are multiple convex grooves 80 and T-shaped sliders 70.

[0095] In the above solution, by having multiple convex grooves 80 and multiple T-shaped sliders 70, the connection between the convex grooves 80 and the T-shaped sliders 70 can be improved.

[0096] In some embodiments, a convex groove 80 is disposed on a first connector 90, and the first connector 90 is fixed to a first main body portion 20 or a second main body portion 30.

[0097] Please continue to refer to Figure 9 In some embodiments, the first connector 90 includes a first part 910, a second part 920 and a third part 930 connecting the first part 910 and the second part 920. The first part 910 is connected to the first main body 20 or the second main body 30, and the second part 920 is connected to the support structure 623.

[0098] That is, when a sliding connection is used, the convex groove 80 can be fixed to the first main body 20 or the second main body 30 through the first connector 90. More specifically, the second part 920 of the first connector 90 is provided with the convex groove 80, and the T-shaped slider 70 is connected to the convex groove 80 on the second part 920.

[0099] It should be noted here that when choosing a sliding connection method, the T-slider 70 should be positioned in a location that does not obstruct the normal operation of other components, for example... Figure 9 As shown, the T-shaped slider 70 can be set at the bottom of the support structure 623.

[0100] Here is a brief description Figure 9 The connection process between the main screen 20 and the secondary board 30 is shown below:

[0101] First, the first connecting component 50 is fixed to the main screen 20 by threaded connection.

[0102] Next, the second connecting component 60 is assembled into the convex groove 80 of the connector of the sub-plate 30 via the T-shaped slider 70. The convex groove 80 is designed with large and small ends. The T-shaped slider 70 is first inserted into the large end and then slid into the small end to realize the connection between the second connecting component 60 and the sub-plate 30.

[0103] Finally, the first sub-component 610 is connected to the elastic component 621. The first sub-component 610 slides towards the main screen 20 within the sliding part 622 until it makes threaded contact with the first connecting component 50. Then, the first sub-component 610 is rotated. When the first sub-component 610 rotates to the limiting structure position of the elastic component 621 (i.e., the junction between the first sub-component 610 and the sliding part 622), the first sub-component 610 and the second sub-component 620 will no longer move relative to each other. When the first sub-component 610 rotates next, it will pull the sub-plate 30 to move towards the main screen 20, thereby locking the main screen 20 and the sub-plate 30 together.

[0104] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
