[0002] Interactive smart tablets integrate multiple functions of projectors, electronic whiteboards, screens, speakers, televisions, and video conferencing terminals. They are widely used in education and teaching, corporate meetings, commercial displays, and other fields, and can effectively improve the communication environment and enhance group communication efficiency.

[0003] Traditional interactive flat panels generally include a display module and an aluminum frame surrounding the outside of the display module. The frame is provided with a snap-in groove for snapping in the filter strip. The glass substrate is inserted into the filter strip and clamped by the filter strip. The back panel is overlapped and screwed to the supporting surface of the frame.

[0004] However, traditional interactive flat panels are inconvenient to install because the filter strips need to be clipped into the smaller clipping slots of the aluminum profile.

[0060] To make the purpose, technical solutions, and advantages of this application more clear, the embodiments of this application will be further described in detail below with reference to the accompanying drawings. It should be understood that the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0061] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0062] In the description of this application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In addition, in the description of this application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0063] Traditional interactive tablets generally include a display module and a frame surrounding the display module. The frame is generally made of aluminum profiles. A touch frame is installed inside the frame. The touch frame includes a touch frame PCBA and infrared transmitters / infrared receivers arranged on the touch frame PCBA.

[0064] An infrared transmitter is mounted on the touch frame PCBA within one of the two opposing frames of the interactive tablet, while an infrared receiver is mounted on the touch frame PCBA within the other frame. These infrared transmitters and receivers form an infrared detection network on the interactive tablet. Touching an object (such as a finger) modifies the infrared radiation at the touch point, which is then converted into the coordinates of the touch point, enabling a response.

[0065] To filter the light from the infrared transmitter and receiver, the interactive flat panel also features a filter strip on the frame to remove stray light. Specifically, traditional interactive flat panels have a snap-in slot on the frame, into which the filter strip is mounted. The filter strip has mounting slots, into which the glass substrate of the display module fits, thereby being clamped by the filter strip. The back panel of the interactive flat panel overlaps the frame and is screwed to the frame's supporting surface.

[0066] However, during the assembly process of traditional interactive flat panels, the filter strips need to be clipped into the smaller clipping slots of the aluminum profile, which is inconvenient to install. In addition, the glass substrate is limited by the clamping effect of the filter strips alone, which makes the glass substrate unstable and easily fall out of the filter strips.

[0067] To solve the above problems, the present application provides an interactive panel (not shown), please refer to Figure 1-8 As shown, the interactive panel includes a frame 1, a back plate 21, a glass substrate 22, a filter strip 3 and a glass pressing block 5, the filter strip 3 is arranged in the internal cavity of the frame 1, and part of the filter strip 3 extends into the opening 10 of the frame 1 to limit the cooperation with the support part 111 in the height direction of the frame 1, realizing the installation of the filter strip 3, and the deformation of the frame 1 can be avoided; the glass substrate 22 extends into the opening 10 of the frame 1 and is installed on the part of the filter strip 3 located in the opening 10, the fixed end 501 of the glass pressing block 5 is fixedly arranged on the support part 111, the abutting end 502 of the glass pressing block 5 abuts against the glass substrate 22, and the back plate 21 is fixedly arranged on the end face of the fixed end 501 of the glass pressing block 5 away from the support part 111, thereby limiting the glass substrate 22, preventing the glass substrate 22 from being pulled out of the filter strip 3, and the installation of the glass substrate 22 is more stable.

[0068] It should be noted that the interactive panel involved in the present application can be an electronic device with functions of writing, commenting, drawing, multimedia entertainment and network conference, and the interactive panel can integrate human-computer interaction, panel display, multimedia information processing and network transmission, and can be applied to office, teaching, graphic-text interactive demonstration and other scenes.

[0069] The specific structure of the interactive panel will be described below in combination with specific embodiments.

[0070] Please refer to Figure 1-8 As shown, the frame 1 is arranged on the circumferential side of the back plate 21 and the glass substrate 22, and the frame 1 includes a first plate body 113 and a second plate body 114 arranged in the height direction of the frame 1, wherein the height direction of the frame 1 refers to the arrow Z direction in Figure 5 and Figure 7 The first plate body 113 and the second plate body 114 constitute the boundary of the internal cavity of the frame 1, one end of the first plate body 113 close to the glass substrate 22 is formed with a support part 111, and the support part 111 and the second plate body 114 are arranged with a spacing to form an opening 10 communicating the internal cavity of the frame 1.

[0071] The filter strip 3 is arranged in the internal cavity of the frame 1, and part of the filter strip 3 extends into the opening 10 to limit the cooperation with the support part 111 in the height direction of the frame 1, the glass substrate 22 extends into the opening 10 and is installed on the part of the filter strip 3 located in the opening 10, the fixed end 501 of the glass pressing block 5 is fixedly arranged on the support part 111, the abutting end 502 of the glass pressing block 5 abuts against the glass substrate 22, and the back plate 21 is fixedly arranged on the end face of the fixed end 501 of the glass pressing block 5 away from the support part 111.

[0072] The filter strip 3 is installed within the internal cavity of the frame 1, and the filter strip 3 can be limited in position by the internal cavity of the frame 1, thereby achieving installation of the filter strip 3. Since the glass block 5 is installed on the support portion 111, and the back plate 21 is installed on the end surface of the filter strip 3 at the fixed end 501 of the glass block 5 away from the support portion 111, the frame 1 is prone to deformation during assembly. By limiting the support portion 111 in the height direction of the frame 1, the deformation of the support portion 111 can be reduced, and the stability of the support portion 111 supporting the glass block 5 and the back plate 21 can be improved.

[0073] In some embodiments, the shape of the filter strip 3 is adapted to the cavity structure of the frame 1, and the filter strip 3 is laterally inserted into the frame 1. Compared with the prior art method of snap-fitting the filter strip 3 to the frame 1, the assembly of the filter strip 3 of the present invention is simpler and more convenient.

[0074] Please refer to Figure 5 , Figure 5 Schematic diagram of a partial structure of an interactive tablet in an embodiment of the present invention. In some embodiments, a receiving cavity 30 is provided inside the filter bar 3 , and the interactive tablet further includes a touch frame 4 , which is inserted into the receiving cavity 30 .

[0075] Specifically, along the height direction of the frame 1, two opposite cavity walls in the accommodating cavity 30 are provided with sliding grooves, and the touch frame 4 is embedded in the two oppositely arranged sliding grooves to achieve convenient installation and positioning of the touch frame 4. The touch frame 4 includes a touch frame PCBA and an infrared emitting / infrared receiving element provided on the touch frame PCBA. An infrared emitting element is provided on the touch frame PCBA in one of the two opposite frames 1 of the interactive tablet, and an infrared receiving element is provided on the touch frame PCBA in the other frame 1. The infrared emitting element and the infrared receiving element form an infrared detection network on the interactive tablet. The object of the touch operation (such as a finger) can change the infrared light of the contact point, which is then converted into the coordinate position of the touch to achieve the response of the operation.

[0076] Compared to traditional interactive tablets, where the touch frame is mounted directly on the frame, the touch frame is more likely to scratch the circuitry during assembly, causing short circuits. Since the filter strip 3 is typically extruded and made of a soft, insulating material, this application inserts the touch frame 4 into the filter strip 3. This not only improves the sealability of the touch frame 4 during installation, but also makes it less likely to scratch the circuitry during assembly, reducing the probability of short circuits.

[0077] For details, please refer to Figure 5 and Figure 7 , Figure 7This is a cross-sectional view of the filter strip 3 in an embodiment of the present invention. In some embodiments, the top and bottom walls of the accommodating cavity 30 are provided with slide grooves. The slide groove located on the top wall of the accommodating cavity 30 is a first slide groove 35, and the slide groove located on the bottom wall is a second slide groove 36. The top of the touch frame 4 is confined within the first slide groove 35, and the bottom of the touch frame 4 is confined within the second slide groove 36. The provision of the first slide groove 35 and the second slide groove 36 can limit and secure the touch frame 4, facilitating its installation while also preventing it from moving around.

[0078] Please continue to refer to Figure 7 In some embodiments, the first slide groove 35 and the second slide groove 36 are both set through the end of the filter bar 3, so that the touch frame 4 can be inserted into the accommodating cavity 30 from the end of the filter bar 3, which is convenient for installation.

[0079] For further information, please refer to Figure 5 The portion of the filter strip 3 that extends into the opening 10 is provided with an embedding groove 31, and the glass substrate 22 is inserted into the embedding groove 31. Thus, the embedding groove 31 can limit and secure the glass substrate 22. During assembly, the fixing end 501 of the glass pressing block 5 is fixed to the support portion 111, and the abutting end 502 of the glass pressing block 5 abuts against the glass substrate 22. At this point, the glass substrate 22 is not only limited and secured by the embedding groove 31, but also abutted and secured against the glass substrate 22 in the height direction of the frame 1 by the glass pressing block 5, thereby improving the stability of the assembly of the glass substrate 22 and reducing the risk of the glass substrate 22 falling off from the filter strip 3.

[0080] In some embodiments, the frame 1 is formed from sheet metal by stamping and rolling, with fewer processing steps and a short delivery cycle. The prepared frame 1 has a simple structure and relatively low cost.

[0081] like Figure 6 As shown, Figure 6 1 is a cross-sectional view of a frame body in an embodiment of the present invention. In some embodiments, the frame 1 further includes a panel 112, which is connected between the first plate 113 and the second plate 114 and is arranged to form a cavity structure (not shown). The end of the first plate 113 away from the panel 112 forms a support portion 111. The frame 1 is integrally formed by sheet metal stamping and rolling. Since the frame 1 is surrounded by the panel 112, the first plate 113 and the second plate 114, a semi-enclosed structure with an opening 10 is formed. The structure is relatively simple and the semi-enclosed structure is relatively easy to prepare.

[0082] In some embodiments, the enclosure 112 , the first plate 113 , the second plate 114 and the support portion 111 are integrally formed. The frame 1 as an integral structure does not need to be assembled, and the integral structure of the frame 1 has a higher supporting strength.

[0083] In addition, the outer surface formed by the enclosure 112, the first plate body 113 and the second plate body 114 serves as the appearance and shape of the product. The surface treatment uses a powder spraying process, which does not produce sewage during the treatment process and is more environmentally friendly. The specific powder spraying process belongs to the existing technology and will not be repeated here.

[0084] For further information, please refer to Figure 6 , Figure 6 This is a cross-sectional view of the frame body in an embodiment of the present invention. In some embodiments, the support portion 111 includes a limiting segment 1111 and a supporting segment 1112. The limiting segment 1111 and the supporting segment 1112 are arranged at an angle. The limiting segment 1111 extends along the height direction of the frame 1, and the supporting segment 1112 extends in a direction away from the internal cavity of the frame 1; the supporting segment 1112 and the first plate 113 are spaced apart along the height direction of the frame 1 to form an opening 10, and the fixed end 501 of the glass block 5 is fixed to the supporting segment 1112. The filter strip 3 and the supporting segment 1112 are limited in the height direction of the frame 1, and the limiting segment 1111 can play a role in limiting the back panel 21.

[0085] It should be noted that the angle formed between the limiting section 1111 and the supporting section 1112 should not include the cases of 0° and 180°, because when the angle formed between the limiting section 1111 and the supporting section 1112 is 0° and 180°, the supporting section 1112 cannot achieve the function of supporting the back panel 21 and the glass pressing block 5 in the height direction of the frame 1.

[0086] Please refer to Figure 6 In some embodiments, the limiting segment 1111 and the supporting segment 1112 are perpendicularly disposed to form an L-shaped structure. In this way, the supporting segment 1112 can support the back panel 21 and the glass pressing block 5 in the height direction of the frame 1. Of course, in other embodiments, the limiting segment 1111 and the supporting segment 1112 can form an acute angle or an obtuse angle. As long as the supporting portion 111 formed by the angle between the limiting segment 1111 and the supporting segment 1112 can support the glass pressing block 5, it is sufficient. This will not be elaborated here.

[0087] like Figure 5 and Figure 7 As shown, the filter strip 3 is provided with a limiting notch 32 recessed into the interior of the accommodating cavity 30. The support portion 111 extends into the limiting notch 32 and cooperates with the limiting notch 32 in the height direction of the frame 1. Since the back panel 21 is fixed to the support portion 111 via the fixed end 501 of the glass block 5, a certain force is exerted on the support portion 111, thereby causing the support portion 111 and even the frame 1 to deform. The limiting notch 32 can limit the support portion 111, thereby reducing the deformation of the support portion 111 and even the frame 1, thereby improving the stability of the installation of the back panel 21.

[0088] It is understandable that, in order to improve the fit between the limiting notch 32 and the support portion 111 , in some embodiments, the shape and structure of the limiting notch 32 is configured to fit the support portion 111 .

[0089] For example, see Figure 5 In this embodiment, the limiting notch 32 is a 90° L-shaped notch, and the limiting section 1111 and the supporting section 1112 are vertically arranged, and the formed supporting portion 111 also has an L-shaped structure. In this way, the supporting portion 111 can be adapted to the limiting notch 32, thereby ensuring that the limiting notch 32 can be limitedly matched with the supporting portion 111 in the height direction of the frame 1.

[0090] Of course, in some other embodiments, the limiting notch 32 can also be a notch of other shapes. It only needs to match the shape and structure between the limiting notch 32 and the supporting portion 111, so that the limiting notch 32 can support the supporting portion 111 in the height direction of the frame 1. We will not go into details here.

[0091] In some embodiments, the filter strip 3 is made of PC (Polycarbonate) material through extrusion molding. This material is soft and insulating. When the touch frame 4 is installed in the filter strip 3, it can prevent the circuit on the touch frame 4 from being scratched during the assembly process of the touch frame 4. At the same time, the filter strip 3 itself is insulated, which can also reduce the probability of short circuiting of the touch frame 4 when it is scratched.

[0092] Please refer to Figure 5 In some embodiments, in order to facilitate the installation of the glass substrate 22, the notch of the embedding groove 31 is set toward the back plate 21 and the glass substrate 22. The embedding groove 31 is a U-shaped structure, so that the glass substrate 22 can be overlapped to fix the glass substrate 22.

[0093] Of course, in some other embodiments, the embedding groove 31 may also be in other shapes, as long as the embedding groove 31 can accommodate the glass substrate 22 for positioning and fixing, which will not be elaborated here.

[0094] Please continue to refer to Figure 5 Furthermore, a guiding slope 33 is provided at the notch of the embedding groove 31 , and the guiding slope 33 is used to guide the glass substrate 22 into the embedding groove 31 so as to facilitate the smooth installation of the glass substrate 22 .

[0095] In some embodiments, in order to facilitate the assembly of the glass substrate 22, the slot of the embedding groove 31 is set to be open. In other words, the diameter of the guide slope 33 is continuously increased along the direction from the bottom of the slot to the insertion opening of the slot. This not only guides the installation of the glass substrate 22, but also the guide slope 33 is located on the inner side of the glass substrate 22, which has a more beautiful appearance.

[0096] Based on any of the above examples, please refer to Figure 5 The filter strip 3 has a light emitting surface 34 on one side of the embedded groove 31. Along the height direction of the frame 1, the light emitting surface 34 is located below the embedded groove 31. The angle between the light emitting surface 34 and the glass substrate 22 is a, 90°<a<180°. The angle range is an obtuse angle, which plays a role in reflecting interference signals to counteract signal interference, thereby playing a role in reducing interference signals.

[0097] Optionally, a may be 95°, 120°, 130°, 150° or 175°.

[0098] It is understandable that within the range of 90° < a < 180°, as angle a increases, the reflection effect on interference signals improves, and the anti-interference effect improves. However, a larger angle a results in a larger visible area of ​​the filter strip 3, a visually wider width of the frame 1, and a poor appearance. Furthermore, a larger angle a also causes the infrared signal inside the filter strip 3 to be refracted by the light-emitting surface 34, increasing the signal recognition height, thereby deteriorating the user's writing experience and making misreading more likely. Furthermore, as angle a increases, a greater proportion of the infrared signal inside the filter strip 3 is reflected back by the light-emitting surface 34, resulting in a smaller effective signal.

[0099] Therefore, based on the above considerations, the angle between the light emitting surface 34 and the glass substrate 22 is preferably in the range of 100°≤a≤120°. When a is within this range, the light emitting surface 34 can better reflect the interference signal, while avoiding the filter strip 3 from being visually wider, thereby ensuring a beautiful appearance.

[0100] Furthermore, when 100°≤a≤120°, the infrared signal inside the filter strip 3 can be avoided from being refracted by the light-emitting surface 34, thereby making the signal recognition height higher, ensuring a better writing experience and less prone to misreading; the infrared signal inside the filter strip 3 can emit a sufficient effective signal through the light-emitting surface 34.

[0101] The following will be combined Figures 10 to 13 The disclosed embodiments describe the specific structure of the glass pressing block 5. Figure 10 The structure of the glass pressing block 5 in the embodiment of the present invention is shown in FIG.
