The interactive flat panel includes a frame body and a back panel, wherein the back panel is fixedly attached to the frame body, and at least a portion of the frame body is located on the outer side of the back panel, such that at least a portion of the rear side of the frame body is exposed from the outer side of the back panel, forming a mounting portion. The interactive flat panel of this application also includes an antenna assembly mounted on the mounting portion. In the main viewing direction of the interactive flat panel, the antenna assembly is completely obscured by the frame body, or by the frame body and the back panel.

Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more particularly to an interactive flat panel. Background Technology

[0002] In related technologies, interactive flat panels are generally equipped with modules such as antenna modules and human body detection modules to provide different interactive functions.

[0003] Taking an interactive flat panel with an antenna module as an example, the antenna module is set inside the device frame. By setting a corresponding fixing structure between the antenna module and the device frame, the antenna module can be relatively fixed to the device frame. In addition, in order to prevent the antenna signal from being shielded or interfered with by the frame, a corresponding clearance area needs to be reserved inside the device frame for the antenna module, and through holes corresponding to the antenna module are opened on the device frame.

[0004] However, in the aforementioned antenna module mounting structure, the through holes on the device frame not only reduce the overall visual appeal of the product but also affect the structural strength of the device frame, making the product prone to deformation during handling or use. Furthermore, because a clearance area needs to be reserved within the device frame, the antenna module occupies a significant amount of layout space within the frame, which is detrimental to the design of narrow-bezel products. Summary of the Invention

[0005] The purpose of this application is to provide an interactive flat panel that solves the problems that the structural strength of the device frame of the interactive flat panel is affected by the installation structure of the antenna module, and that the antenna module occupies a large installation space within the device frame.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] An interactive flat panel is provided, comprising:

[0008] The border itself; and

[0009] A back panel is fixedly attached to the frame body, with at least a portion of the frame body located on the outside of the back panel, such that at least a portion of the rear side of the frame body is exposed from the outside of the back panel and forms a mounting portion.

[0010] An antenna assembly is mounted on the mounting portion, and in the main viewing direction of the interactive flat panel, the antenna assembly is completely obscured by the frame body, or the frame body and the back panel.

[0011] The beneficial effects of this application are as follows: the back panel of the interactive flat panel overlaps with one side of the frame body, so that the rear side of the frame body can be exposed from the outside of the back panel and form a mounting part for providing an antenna assembly mounting position. When the antenna assembly is installed in the mounting part, in the main viewing direction of the interactive flat panel, the antenna assembly is completely covered by the frame body, or the frame body and the back panel. There is no need to open through holes on the frame body corresponding to the antenna assembly position, thereby saving the corresponding manufacturing process, while also enhancing the structural strength of the frame body and improving the overall visual effect of the product.

[0012] The antenna assembly is located on the rear side of the frame body so that it can be exposed outside the frame body (rear side). The antenna assembly being located outside the frame body saves the clearance area required for the antenna assembly, allowing its size to be reduced and improving the structural compactness of the frame body, which is beneficial for the application of narrow bezel products.

[0023] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] In the description of this application, unless otherwise expressly specified and limited, the terms "connected" and "fixed" 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. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] In related technologies, interactive flat panels are generally equipped with modules such as antenna modules and human body detection modules to provide different interactive functions.

[0027] Taking an interactive flat panel with an antenna module as an example, as the background technology shows, the antenna module is set inside the device frame. By setting a corresponding fixing structure between the antenna module and the device frame, the antenna module can be relatively fixed to the device frame. In order to prevent the antenna signal from being shielded or interfered with by the frame, a corresponding clearance area needs to be reserved inside the device frame for the antenna module, and through holes corresponding to the antenna module are opened on the device frame.

[0028] However, in the aforementioned antenna module mounting structure, the through-holes on the device frame not only reduce the overall visual appeal of the product but also affect the structural strength of the device frame, making the product prone to deformation during handling or use. Although some interactive flat panel products use Mylar sheets to cover the through-holes, it is clear that due to the different materials of the Mylar sheets and the device frame, they still affect the overall visual appeal of the product. Furthermore, over time, the Mylar sheets on the device frame are prone to failure and detachment, resulting in low reliability. Moreover, because a clearance area needs to be reserved within the device frame, the antenna module occupies a significant amount of layout space within the device frame, which is detrimental to the design of narrow-bezel products. Therefore, this embodiment provides the following solution.

[0029] This embodiment provides an interactive flat panel. It is understood that the mounting structure of the antenna component 30 used in this interactive flat panel can also be applied to other electronic devices. The electronic devices described in this embodiment are generally devices that use electronic technology (including) software to perform functions, in order to realize human-computer interaction functions to a certain extent. These include, but are not limited to, electronic computers, robots, display terminals, etc.

[0030] Interactive flat panels can be used as conference flat panels, smart blackboards, commercial displays, and other display devices. They can also be integrated into televisions, computer monitors, and other display devices. Interactive flat panels allow for human-computer interaction by using touch technology to operate the content displayed on the screen. They integrate one or more functions such as projectors, whiteboards, screens, speakers, televisions, and video conferencing terminals. In practical applications, the hardware of an interactive flat panel consists of a touch membrane assembly, a screen 60, and a control unit, all assembled together by a unified structural system supported by a dedicated software system. The screen 60 works in conjunction with the touch membrane assembly to achieve display and touch functions. Users can interact with the display screen using their fingers or a stylus. The intelligent processing system generates handwriting based on the user's touch input and displays it on the screen, or generates control operations based on the user's touch input to process the displayed content.

[0031] To address the aforementioned technical issues, this interactive flat panel modifies and optimizes the assembly structure between the antenna assembly 30 and the frame body 10, thereby resolving a series of problems such as the low structural strength of the frame body 10 and its large size.

[0032] Please refer to Figures 1-5 The interactive flat panel includes a frame body 10, which can be made of an insulating material, such as plastic, to prevent interference with the signal transmission and reception performance of the antenna assembly 30. Alternatively, to ensure the structural strength of the interactive flat panel meets product design requirements, the frame body 10 can also be made of a highly conductive material, such as aluminum or stainless steel, as long as it provides a suitable clearance area for the antenna assembly 30.

[0033] In one embodiment, the frame body 10 can be a profile frame or a sheet metal frame. In terms of cross-sectional structure, the profile frame is generally a closed frame structure, mainly formed by extrusion molding. The sheet metal frame, on the other hand, is generally an open structure, mainly formed by bending, rolling, stamping, and other processes. Taking the frame body 10 as a profile as an example, the frame body 10 can be a through-hole structure, so that a space for accommodating various functional modules is formed within the frame body 10, or a corresponding clearance area is provided for the antenna assembly 30. A clearance hole can be provided through the side wall of the frame body 10 on the rear side (i.e., in the direction indicated by the arrow in the attached figure) to connect the aforementioned accommodating space with the external environment of the frame body 10. Whether a clearance hole needs to be provided on the frame body 10, and the specific structure and location of the clearance hole, can be determined according to the requirements of the antenna assembly 30 located on the interactive flat panel and the applied electronic equipment. Generally, the clearance hole is usually provided in the area where the antenna assembly 30 is located; this embodiment does not specifically limit this.

[0034] like Figures 1-5As shown, according to the above embodiment, for ease of understanding, the interactive flat panel structure also includes a screen 60. The frame body 10 defines a display area 61 by enclosing it, allowing the screen 60 to cover the display area 61 when connected to the frame body 10, thereby providing image display functionality. It should be understood that the screen 60 includes LED (Light Emitting Diode) displays, OLED (Organic Light-Emitting Diode) displays, LCD (Liquid Crystal Display) displays, etc. The side of the interactive flat panel that provides image display functionality via the screen 60, and the direction the screen 60 faces, is the front side of each component in this embodiment, i.e., the "front" direction indicated by the arrow in the attached figures. The side away from the screen 60, i.e., the side where the back panel 20 faces in this embodiment, is the rear side of each component, i.e., the "rear" direction indicated by the arrow in the attached figures.

[0035] The interactive flat panel also includes a back panel 20 disposed on the rear side of the interactive flat panel. In one embodiment, the backlight module of the interactive flat panel can be fixed to the front side of the back panel 20. The interactive flat panel provides the brightness required for image display on the screen 60 through the backlight module and provides a certain degree of protection for the rear side of the interactive flat panel.

[0036] In one embodiment, the back plate 20 and the frame body 10 can be configured as a single piece, which can be manufactured by a one-piece molding process, such as sheet metal, injection molding, 3D printing, casting, etc.

[0037] Please continue to refer to this. Figures 1-5 In this embodiment, the frame body 10 and the back panel 20 are manufactured independently (e.g., the frame body 10 is manufactured using an extrusion process, and the back panel 20 is manufactured using a sheet metal process). They are then assembled using appropriate mounting structures to reduce the processing difficulty of the frame body 10 and the back panel 20. This also suits situations where the frame body 10 and the back panel 20 are manufactured using different materials. Generally, to ensure the seamlessness of the interactive flat panel, the back panel 20 is typically fixedly attached to the rear side of the frame body 10. This prevents the seam between the frame body 10 and the back panel 20 from extending to the rear side of the interactive flat panel in the main viewing direction, thus avoiding light leakage at the rear of the interactive flat panel.

[0038] In order to ensure good protection for the rear of the interactive flat panel and to allow the backlight module located on the front of the back panel 20 to provide the illumination required for image display on the screen 60 as a whole, the bezel body 10 is located at least partially outside the back panel 20, similar to the structure of the screen 60 located on the interactive flat panel. This allows the rear side of the bezel body 10 to be exposed from the outside of the back panel 20 and form the mounting part 11. In this example, the structure of the back panel 20 is similar to that of the screen 60, so that when the bezel body 10 encloses and forms the display area 61, the bezel body 10 can be set along the outer periphery of the screen 60 and the back panel 20, thereby forming the outer periphery structure of the interactive flat panel.

[0039] The interactive flat panel, based on the above structure, also includes an antenna assembly 30. The antenna assembly 30 can be used to support wireless communication in one or more wireless communication frequency bands. That is, the antenna assembly 30 can be used to transmit and receive radio frequency signals, and it integrates functions including but not limited to WIFI, Bluetooth, and network functions.

[0040] In order to reduce the overall visual clutter of the interactive flat panel product while solving the basic problems proposed in this embodiment, the antenna assembly 30 is assembled externally to the frame body 10 and the back plate 20. For example, the antenna assembly 30 is installed on the mounting part 11 of the frame body 10 so that in the main viewing direction of the interactive flat panel, the antenna assembly 30 can be completely blocked by the frame body 10, or completely blocked by the frame body 10 and the back plate 20. This type of arrangement allows the antenna assembly 30 to be fully exposed outside the basic structure of the interactive flat panel. In this embodiment, only the front side of the antenna assembly 30 is obscured by the frame body 10, or by the frame body 10 and the back panel 20. Compared with the antenna structure in the interactive flat panel of related technologies, this embodiment significantly reduces the obstruction area of ​​the antenna assembly 30. Except for its front side, the antenna assembly 30 is not obscured by the frame body 10 and the back panel 20 on its upper, lower, or rear sides. This provides sufficient clearance for the outside of the antenna assembly 30, minimizing the impact of the interactive flat panel on the performance of the antenna assembly 30 and preventing the signals received and / or transmitted by the antenna assembly 30 from being blocked or weakened by the screen 60 or the frame and back panel 20.

[0041] In the above embodiments, if the portion of the antenna assembly 30 used for transmitting and / or receiving radio frequency signals is located on the rear side of the frame body 10, then the rear side of the frame body 10 can have the aforementioned clearance hole corresponding to the position of the antenna assembly 30, so that the clearance hole and the internal accommodating space of the frame body 10 can cooperate to provide sufficient clearance area for the front side of the antenna assembly 30. When the portion of the antenna assembly 30 used for transmitting and / or receiving radio frequency signals is located on the rear side of the back plate 20, then the rear side of the back plate 20 can have a clearance hole corresponding to the position of the antenna assembly 30, so that the radio frequency signal can be transmitted and received through the front side of the display screen. In this case, the signal transmission and reception area of ​​the antenna assembly 30 can be set directly opposite the non-display area 61 of the screen 60, so as to further reduce the signal interference of the screen 60 to the antenna assembly 30.

[0042] In the above embodiments, regardless of whether the part of the antenna assembly 30 used for transmitting and / or receiving radio frequency signals is located on the rear side of the frame body 10 or the rear side of the back panel 20, there is no need to open a corresponding through-hole structure on the front side of the frame body 10 corresponding to the position of the antenna assembly 30. This can save the process steps required in the manufacturing process of the interactive flat panel. In addition, during the assembly process of the antenna assembly 30 and the frame body 10, the assembly accuracy requirements between the antenna assembly 30 and the frame body 10 are reduced. The assembler no longer needs to accurately align the antenna assembly 30 and the through-hole opened on the front side of the frame body 10, which reduces the assembly difficulty of the interactive flat panel. Furthermore, the front side of the frame body 10 does not need to have a through-hole structure at the position corresponding to the antenna assembly 30, thereby improving the integrity of the frame body 10 structure and enhancing its structural strength. The frame body 10 does not need to be reinforced by strengthening the material or by other means of strengthening the structure, which can save on the manufacturing and material costs of the frame body 10. Of course, the frame body 10 with the above structure can also improve the overall visual effect of the interactive flat panel product. The frame body 10 does not need to be covered by Mylar sheets, thus meeting the aesthetic needs of some users.

[0043] In addition, the antenna assembly 30 is located on the back side of the frame body 10, or the frame body 10 and the back panel 20, and is external to the interactive flat panel. That is, the frame body 10 does not need to reserve the required clearance area for the antenna assembly 30, or the clearance area reserved inside the frame body 10 for the antenna assembly 30 can be reduced accordingly, so that the width and thickness of the frame body 10 can be narrowed, which is beneficial to the application of narrow bezel products.

[0044] It should be noted that in the interactive flat panel products of the relevant technology, the outer periphery of the screen 60 and the back panel 20 are generally rectangular. Correspondingly, the frame body 10 on the screen 60 and the back panel 20 also includes frame portions placed on the upper, lower, left and right sides of the screen 60 and the back panel 20. Of course, in other embodiments, the screen 60 and the back panel 20 of the interactive flat panel can also be designed into irregular shapes such as polygons according to the usage scenario or other factors. This example continues with the rectangular structure of the interactive flat panel. Generally, the lower frame body 10 of the interactive flat panel is larger in size than the upper, left, and right frame bodies 10. Correspondingly, the lower frame body 10 provides more internal space, which is configured to accommodate functional modules with different functions, such as a microphone module, a speaker module, a camera module, and the antenna assembly 30 described in this embodiment. Furthermore, the motherboard for electrical connection with the screen 60 is also located at the lower part of the interactive flat panel. Considering all these factors, during the use of the interactive flat panel, the functional modules and the screen 60 (including the motherboard) will cause some interference to the signal transmission and reception of the antenna assembly 30. Therefore, in this embodiment, the antenna assembly 30 is installed on the rear side of the upper frame body 10 of the interactive flat panel, so that the antenna assembly 30 can form a larger assembly gap with other functional modules and electronic components such as the motherboard of the interactive flat panel, thereby reducing the interference caused by the functional modules and electronic components to the antenna module.

[0045] Of course, based on the principles of the above embodiments, in other embodiments, the antenna assembly 30 can also be disposed on the rear side of the frame body 10 located on the left or right side of the interactive flat panel.

[0046] In this embodiment, since the antenna assembly 30 is mounted externally to the frame body 10, the antenna assembly 30 cannot be mounted on the interactive flat panel relying on the frame body 10. Please refer to the appendix for further details. Figures 3-5 In this example, the antenna assembly 30 needs to be mounted on the frame body 10 via the antenna bracket 40. The antenna bracket 40 serves as the main support for the antenna assembly 30 on the frame body 10, and is located between the frame body 10 and the antenna assembly 30 in the assembled state.

[0047] One side of the antenna bracket 40 is mounted on the mounting portion 11 of the frame body 10, while the antenna assembly 30 is mounted on the side of the antenna bracket 40 away from the mounting portion 11. Specifically, the front side of the antenna bracket 40 is fixedly engaged with the frame body 10, and the antenna assembly 30 is mounted on the rear side of the antenna bracket 40 so that the antenna assembly 30 is exposed from the rear side of the antenna bracket 40. This ensures that the structure meets the condition of the antenna assembly 30 being externally placed on the frame body 10, and avoids the presence of the antenna bracket 40 affecting the installation and removal of the antenna assembly 30 on the interactive flat panel.

[0048] In one embodiment, the antenna bracket 40 and the frame body 10 can be configured as a single piece. This can also be understood as the antenna assembly 30 being directly fixed to the rear side of the frame body 10. However, it is clear that with the frame body 10 being formed using an extrusion process, it is impossible to integrally design the antenna bracket 40 onto the frame body 10. The antenna bracket 40 and the frame body 10 need to be processed using injection molding, 3D printing, casting, or other processes. Therefore, in this embodiment, the antenna bracket 40 and the frame body 10 are two independently processed components, subsequently assembled and fitted together using corresponding assembly structures. For example, the frame body 10 is formed using an extrusion process, while the antenna bracket 40 is formed using injection molding, 3D printing, or other processes.

[0049] In one embodiment, the antenna bracket 40 and the antenna assembly 30, as well as the antenna bracket 40 and the frame body 10, can be configured to be non-removable after installation. This ensures that the antenna assembly 30, when mounted on the frame body 10 via the antenna bracket 40, can be relatively stably placed on the interactive flat panel, avoiding the impact on the assembly strength of the antenna assembly 30 on the frame body 10 due to its external placement. In this embodiment, however, the antenna bracket 40 and the antenna assembly 30, as well as the antenna bracket 40 and the frame body 10, are both configured to be detachably connected. This ensures that the antenna bracket 40 can be stably placed on the frame body 10, and the antenna assembly 30 can be stably placed on the antenna bracket 40. While ensuring the antenna assembly 30 can be stably externally placed on the frame body 10, the antenna assembly 30 and the antenna bracket 40 can be disassembled and replaced on the interactive flat panel, extending its service life.

[0050] In the above embodiment, a first fixing structure is provided between the antenna bracket 40 and the frame body 10. The antenna bracket 40 is detachably installed on the mounting part 11 through the first fixing structure. The first fixing structure needs to meet the requirement that the antenna bracket 40 and the frame body 10 can be detached in a stable installation state. That is, the first fixing structure between the antenna bracket 40 and the frame body 10 can be set as a threaded connection structure, a snap-fit ​​connection structure, a plug-in fixing, etc.

[0051] And please refer to Figures 3-4 With the antenna assembly 30 and antenna bracket 40 installed and engaged, the first fixing structure is at least partially exposed from the rear side of the interactive panel, allowing personnel to operate the first fixing structure from the rear side of the interactive panel. For example, if the first fixing structure is a threaded connection, the screw head can be exposed from the rear side of the interactive panel; if the first fixing structure is a snap-fit ​​connection, the part used to operate the snap-fit ​​or to apply movement in the disassembly direction to the snap-fit ​​needs to be exposed from the rear side of the interactive panel; if the first fixing structure is a plug-in fixing structure, the part used to apply movement in the disassembly direction to the plug-in structure needs to be exposed from the rear side of the interactive panel. This achieves the purpose of meeting the assembly and disassembly requirements of the antenna bracket 40 and the frame body 10.

[0052] Please refer to the attached document. Figures 3-4 As one embodiment of the first fixing structure, the first fixing structure in this embodiment adopts a threaded connection structure. Specifically, the first fixing structure includes a threaded hole 12 formed on the frame body 10, a fixing arm 41 disposed on the antenna bracket 40, and a fixing hole located on the fixing part. In the assembled state of the antenna bracket 40 and the frame body 10, the antenna bracket 40 abuts against the rear side of the frame body 10 through the fixing arm 41, so that the positioning hole 411 located on the fixing arm 41 can be in a state of alignment with the threaded hole 12 located on the rear side of the frame body 10. Here, the diameter of the positioning hole 411 needs to be set to be larger than that of the threaded hole 12. The hole diameter is designed to allow the fixing screw 13 to pass through the positioning hole 411 from the rear side of the fixing arm 41 to the front side and be threaded into the threaded hole 12. It should be understood that the hole diameter of the positioning hole 411 should be set to be smaller than the screw head of the fixing screw 13 and larger than the threaded section of the fixing screw 13. This ensures that after the fixing screw 13 is screwed into the threaded hole 12 through its threaded section, the screw head of the fixing screw 13 cannot pass through the positioning hole 411. That is, the fixing screw 13 can abut against the rear side of the fixing arm 41 through its screw head and push the antenna bracket 40 forward (towards the frame body 10) so that the antenna bracket 40 is finally stably assembled on the rear side of the frame body 10.

[0053] Based on the above structural form, in one embodiment, in order to make the assembly relationship between the antenna bracket 40 and the frame body 10 more reliable and stable, the first fixing structure specifically includes threaded holes 12 opened on the frame body 10 and located on opposite sides of the mounting part 11. It can be understood that there are at least two threaded holes 12 in this example. On the basis of ensuring that threaded holes 12 are provided on both opposite sides of the frame body 10 located on the mounting part 11, multiple threaded holes 12 that are spaced apart from each other can also be opened on the periphery of the frame body 10 located on the mounting part 11. Accordingly, the antenna bracket 40 is provided with fixing arms 41 and positioning holes 411 corresponding to the number and position of the threaded holes 12 on the frame body 10, so that when the antenna bracket 40 is close to the mounting part 11, each positioning hole 411 can be aligned and engaged with each threaded hole 12. This improves the assembly stability of the antenna bracket 40 and the frame body 10 when the fixing screws 13 are fixed in each positioning hole 411 and threaded hole 12, and also meets the requirement that the antenna bracket 40 and the frame body 10 are detachable.

[0054] Furthermore, in the above embodiment, in order to control the width dimension of the border body 10 (the distance between the inner side of the border body 10 and the outer side of the border body 10) and reduce the width dimension of the border body 10 to make the interactive flat panel more favorable to the current trend of narrow border design, in this example, each threaded hole 12 is spaced apart along the length direction of the border body 10.

[0055] In the above embodiment, the purpose of positioning the antenna bracket 40 with the frame body 10 by setting the extended fixing arm 41 is to allow the fixing arm 41 to be exposed on the rear side of the interactive flat panel when the frame body 10, the antenna bracket 40 and the antenna assembly 30 are installed together, so as to avoid the fixing arm 41 being blocked by the antenna assembly 30 when the antenna assembly 30 is assembled on the antenna bracket 40.

[0056] In the embodiment where the portion of the antenna assembly 30 used for transmitting and receiving radio frequency signals is located on the rear side of the frame body 10, i.e., the rear side of the frame body 10 has a clearance hole corresponding to the antenna assembly 30, the mounting portion 11 of the frame body 10 is located around the clearance hole. When the antenna bracket 40 and the frame body 10 are in the installed and fitted state, the antenna bracket 40 is attached to the rear side of the frame body 10 by the fixing arm 41. The fixing arm 41 can play a certain role in front limiting the antenna bracket 40. In this embodiment, the fixing arm 41 is set to two corresponding threaded holes 12, and the two fixing arms 41 are respectively set at opposite ends of the antenna bracket 40 to prevent the antenna bracket 40 from being inserted into the receiving space of the frame body 10 through the clearance hole, thereby affecting the assembly accuracy of the antenna assembly 30 on the frame body 10 and ensuring that the antenna assembly 30 can provide good signal transmission and reception functions.

[0057] The above-described embodiment provides an implementation that allows the antenna bracket 40 to be stably mounted on the frame body 10 and to be detached from the frame body 10. During the assembly of the antenna bracket 40 with the frame body 10, to ensure rapid positioning between the positioning hole 411 and the threaded hole 12, the assembly positions of the antenna bracket 40 and the subsequently assembled antenna assembly 30 on the frame body 10 are relatively accurate. In this example, a first positioning structure is provided between the antenna bracket 40 and the frame body 10, and the antenna bracket 40 is positioned and engaged with the frame body 10 through the first positioning structure. In one embodiment, the first positioning structure can be configured as a limiting plate (not shown) fixed on the antenna bracket 40. In an embodiment where the antenna bracket 40 is disposed on the upper side of the frame body 10, the antenna bracket 40 can be attached to the side (outer side) of the frame body 10 away from the back plate 20 by the limiting plate, so that it can be positioned with the frame body 10 in the horizontal direction; or, the first positioning structure can be configured as a protrusion and a concave part respectively located on the antenna bracket 40 (as shown in the figure), so that the antenna bracket 40 is positioned on the frame body 10 by the matching of the protrusion and concave part.

[0058] In this example, please refer to Figures 3-8 Considering the narrow bezel design of the interactive flat panel, the first positioning structure adopts a structure in which a first positioning protrusion 412 and a first positioning recess 14 are set between the frame body 10 and the antenna bracket 40, so as to avoid the first positioning structure protruding beyond the antenna bracket 40 and / or the outer side of the frame body 10.

[0059] Specifically, the first positioning protrusion 412 and the first positioning recess 14 are structurally compatible. They can be configured as protruding columnar structures with corresponding countersunk holes or through holes, or as protruding plate-like structures with corresponding grooves, etc., so that the antenna bracket 40 and the frame body 10 can be positioned and engaged by the first positioning protrusion 412 and the first positioning recess 14 before being fixedly engaged by the first fixing structure. In this example, the first positioning protrusion 412 and the first positioning recess 14 are respectively disposed on the antenna bracket 40 and the frame body 10. Furthermore, to avoid affecting the width dimension of the frame body 10, the first positioning protrusion 412 and the first positioning recess 14 are located on the front side of the antenna bracket 40 and the rear side of the frame body 10, respectively. Their extension directions are both set to the front-rear direction of the interactive flat plate; that is, the first positioning structure will not protrude from the outside of the frame body 10 or the outside of the antenna bracket 40.

[0060] Based on the embodiments provided above, at least two ways of configuring the first positioning protrusion 412 and the first positioning recess 14 are provided below:

[0061] 1. The first positioning protrusion 412 protrudes from the antenna bracket 40, and the first positioning recess 14 is formed in the mounting part 11;

[0062] 2. The first positioning protrusion 412 protrudes from the mounting part 11, and the first positioning recess 14 is formed in the antenna bracket 40.

[0063] In this embodiment, considering that the antenna bracket 40 is generally manufactured using injection molding and other processes, and that the frame body 10 is manufactured using extrusion, additive manufacturing is easier to perform on the antenna bracket 40. Similarly, subtractive manufacturing processes such as drilling are easier to implement on the extruded frame body 10. Compared to machining grooves on the antenna bracket 40 and protrusions on the frame body 10, the above method is obviously more beneficial to the manufacturing of the interactive flat panel in this embodiment, reducing manufacturing difficulty and cost, and improving production efficiency.

[0064] In the above description of the first positioning structure, in an embodiment where the first fixing structure includes a fixing arm 41 disposed on the antenna bracket 40, the first positioning protrusion 412 protrudes from the fixing arm 41 and is located on the side of the positioning hole 411, while the corresponding first positioning recess 14 is formed on the mounting portion 11 of the frame body 10 and is located on the side of the threaded hole 12.

[0065] According to the embodiment described above, where a first fixing structure is provided between the antenna bracket 40 and the frame body 10, the antenna assembly 30 in this example includes a dielectric substrate 31 and an antenna unit 32. The dielectric substrate 31 can be a PCB board with various dielectric constants. The dielectric substrate 31 can be a single-layer board, a two-layer board, or a multi-layer board. The dielectric substrate 31 can be used to support various electronic components of the antenna assembly 30 and to arrange wiring layers for electrically connecting various electronic components. The antenna unit 32 is a unit component that can realize the transmission and / or reception of radio frequency signals as described above. It can include an antenna circuit disposed on the dielectric substrate 31 and an antenna radiator disposed on the dielectric substrate 31 and electrically connected to the antenna circuit. The antenna circuit is communicatively connected to the motherboard of the interactive flat panel to realize the transmission of signals between the control unit and the antenna radiator. The antenna radiator is used to receive signals sent from the outside or to send signals transmitted from the antenna circuit to the antenna radiator to the outside of the interactive flat panel.

[0066] like Figures 3-6 As shown, the dielectric substrate 31 serves as the carrier of the antenna assembly 30. The antenna assembly 30 is mounted on the antenna bracket 40 via the dielectric substrate 31. The antenna element 32 is located on the dielectric substrate 31 to realize the signal receiving and / or transmitting functions of the antenna assembly 30. In order to ensure that the antenna assembly 30 can be stably mounted on it, the antenna bracket 40 has a fixing groove 42 on its rear side that is adapted to the structure of the dielectric substrate 31, and the dielectric substrate 31 is accommodated in the fixing groove 42.

[0067] In one embodiment, when the dielectric substrate 31 is housed in the fixing groove 42, the antenna support 40 can be fixed to the dielectric substrate 31 by the groove wall of the fixing groove 42 abutting against the edge of the dielectric substrate 31.

[0068] In this embodiment, the antenna support 40 and the dielectric substrate 31 are mounted and cooperated by a second fixing structure. It can be understood that since the antenna assembly 30 generally uses a PCB board as the dielectric substrate 31, and it is not easy to process related fixing structures on the PCB board, the second fixing structure in this embodiment is set on the fixing groove 42 of the antenna support 40. The dielectric substrate 31 is detachably mounted on the fixing groove 42 through the second fixing structure. In this example, the second fixing structure can be set as a fixing structure such as a buckle or a limiting plate that can move relative to the antenna support 40.

[0069] Of course, in other embodiments, the second fixing structure can also be configured in a similar form to the first fixing structure. For example, a first fixing hole (not shown) can be provided at the bottom of the fixing groove 42, and a second fixing hole (not shown) can be provided on the dielectric substrate 31, so that the two can be fixed by means of fasteners passing through. Alternatively, the second fixing structure can also be configured as a guide groove provided on the groove wall of the fixing groove 42 or at other positions outside the guide groove, so that the dielectric substrate 31 can be inserted into the guide groove, move into the fixing groove 42 under the guidance of the guide groove, and be stably held in the fixing groove 42 by fixing with the guide groove.

[0070] Please continue to refer to the appendix. Figures 3-4 , Figures 6-8In one specific embodiment, the second fixing structure is a snap-fit ​​structure 421 disposed on the fixing groove 42. The dielectric substrate 31 and the antenna support 40 are engaged by snap-fit ​​structure 421. The snap-fit ​​structure 421 is specifically located on the groove wall of the fixing groove 42, or it is disposed on one side of the fixing groove 42. The snap-fit ​​structure 421 includes an elastic arm 4211 with a first end fixedly connected to the antenna support 40 and a second end extending rearward, and a fastener 4212 fixed to the second end of the elastic arm 4211. The fastener 4212 protrudes from the elastic arm 4211, so that an installation gap 4213 is formed between the snap-fit ​​structure 421 and the bottom of the fixing groove 42. The installation gap 4213 is specifically located between the part of the fastener 4212 protruding from the elastic arm 4211 and the bottom of the fixing groove 42. The dielectric substrate 31 can be secured in the installation gap 4213 by snap-fit ​​structure 421. During the installation of the dielectric substrate 31 and the antenna bracket 40, the dielectric substrate 31 can be installed from the opening of the fixing groove 42 towards the bottom of the fixing groove 42. During this process, the dielectric substrate 31 will abut against the fastener 4212 of the snap-fit ​​structure 421, and apply a force to the fastener 4212 in a direction away from the dielectric substrate 31. Under the action of the dielectric substrate 31, the fastener 4212 drives the elastic arm 4211 to deform relative to the antenna bracket 40 in a direction away from the dielectric substrate 31. Finally, the snap-fit ​​structure 421 moves until the dielectric substrate 31 can be inserted into the fixing groove 40. In the state within the slot 42, after the dielectric substrate 31 is placed into the fixing slot 42, the elastic arm 4211 will elastically reset to the position where the fastener 4212 is located on the side of the dielectric substrate 31 away from the bottom of the fixing slot 42 (the rear side of the dielectric substrate 31) when the force of the dielectric substrate 31 is removed. In this way, the opposite two sides (front and rear sides) of the dielectric substrate 31 can be restricted by the bottom of the fixing slot 42 and the snap-fit ​​structure 421, respectively, while the outer edges of the dielectric substrate 31 are constrained by the walls of the fixing slot 42 or the elastic arm 4211. Similarly, when the dielectric substrate 31 needs to be removed from the antenna bracket 40, the user can apply a force to the dielectric substrate 31 in a direction away from the bottom of the fixing slot 42, or the user can apply a force to the snap-fit ​​structure 421 in a direction away from the dielectric substrate 31, thereby causing the snap-fit ​​structure 421 to detach from the dielectric substrate 31 under the action of external force or the action of the dielectric substrate 31, and finally realize the removal of the dielectric substrate 31 from the antenna bracket 40.

[0071] The above embodiments provide a method for stably mounting the dielectric substrate 31 to the antenna bracket 40 and allowing the dielectric substrate 31 to be detached from the antenna bracket 40. During the assembly of the dielectric substrate 31 with the antenna bracket 40, or when the dielectric substrate 31 is fixed in the fixing groove 42 by the snap-fit ​​structure 421, to ensure high positioning accuracy between the dielectric substrate 31 and the fixing groove 42, in this example, a second positioning structure is provided between the dielectric substrate 31 and the antenna bracket 40. During the assembly of the dielectric substrate 31 to the antenna bracket 40, and when the dielectric substrate 31 is housed in the fixing groove 42, the dielectric substrate 31 achieves positioning and engagement with the antenna bracket 40 through the second positioning structure. Unlike the first positioning structure, since the dielectric substrate 31 is a PCB board, it is not easy to fabricate the second positioning structure on the dielectric substrate 31 using additive manufacturing processes. Therefore...

[0072] In this embodiment, a second positioning protrusion 422 and a second positioning recess 311 are provided between the frame body 10 and the dielectric substrate 31. The second positioning protrusion 422 and the second positioning recess 311 are structurally compatible. They can be configured as protruding columnar structures and corresponding countersunk holes or through holes, or they can be configured as protruding plate-like structures and corresponding grooves, so that the dielectric substrate 31 and the antenna support 40 can be positioned and engaged by the second positioning protrusion 422 and the second positioning recess 311 before and after being fixedly engaged by the second fixing structure. Specifically, the second positioning protrusion 422 and the second positioning recess 311 are respectively provided on the dielectric substrate 31 and the antenna support 40. In order to avoid affecting the width dimension of the antenna support 40, the second positioning protrusion 422 and the second positioning recess 311 are respectively located on the rear side of the antenna support 40 and the front side of the dielectric substrate 31. The extension direction of both is set to the front-back direction of the interactive plate, that is, the second positioning structure will not protrude from the outside of the antenna support 40 and the outside of the dielectric substrate 31.

[0073] Based on the embodiments provided above, at least two configurations of the second positioning protrusion 422 and the second positioning recess 311 are provided below:

[0074] 1. The second positioning protrusion 422 protrudes from the antenna support 40, and the second positioning recess 311 is formed on the dielectric substrate 31;

[0075] 2. The second positioning protrusion 422 is protruded on the dielectric substrate 31, and the second positioning recess 311 is formed on the antenna support 40.

[0076] Unlike the first positioning structure, since the dielectric substrate 31 is a PCB board, it is not easy to use additive manufacturing to process the second positioning structure on the dielectric substrate 31. The antenna bracket 40 is generally formed by injection molding and other processes. Therefore, additive manufacturing is easier to process on the antenna bracket 40. Similarly, subtractive manufacturing processes such as drilling are easier to implement on the dielectric substrate 31. Compared with the solutions of processing grooves on the antenna bracket 40 and protrusions on the dielectric substrate 31, it is obvious that the above method is more conducive to the processing of the interactive flat panel of this solution, reducing processing difficulty and cost, and improving production efficiency.

[0077] As described in the above embodiments, the antenna assembly 30 includes a dielectric substrate 31 and antenna elements 32. In one embodiment, a radio frequency (RF) chip corresponding to the number of antenna elements 32 is also disposed on the dielectric substrate 31. Alternatively, the RF chip can also be disposed on the main board of the interactive flat panel. The RF chip can be a Wi-Fi RF chip, such as a Wi-Fi RF chip supporting 2.4G and 5G. Of course, the RF chip can also be other wireless communication chips such as Bluetooth.

[0078] In this example, antenna unit 32 includes a first antenna 321 and a second antenna 322. The first antenna 321 and the second antenna 322 can be used to transmit and / or receive different radio frequency signals, respectively. Correspondingly, the radio frequency chips are configured as a first radio frequency chip corresponding to the first antenna 321 and a second radio frequency chip corresponding to the second antenna 322. According to the above embodiment, in this example, the first antenna 321 can be configured to implement the WIFI function of antenna assembly 30, while the second antenna 322 can be configured to implement the Bluetooth function of antenna assembly 30.

[0079] like Figures 3-5 As shown, in one embodiment, the dielectric substrate 31 is arranged in a vertical direction, which can also be understood as the dielectric substrate 31 being arranged in a position parallel to the screen 60. In this example, the part of the antenna assembly 30 used for transmitting and / or receiving radio frequency signals is arranged on the rear side of the back plate 20. Therefore, the first side of the antenna assembly 30 is connected to the frame body 10 and located on the rear side of the frame body 10, and the second side of the antenna assembly 30 needs to be arranged to extend to the rear side of the back plate 20. The first antenna 321 is arranged on the dielectric substrate 31 located on the rear side of the back plate 20.

[0080] Taking the first antenna 321 used to implement the WIFI function of the antenna assembly 30 as an example, the first antenna 321 is a slot antenna. Figures 3-5The flat, extended portion towards the screen at a direction of 60 is a schematic model of the signal transmission and reception area of ​​the slot antenna, which can also be understood as a schematic model of the front clearance area of ​​the slot antenna. It should be understood that a slot antenna is an antenna formed by opening a slot on a conductor surface, and it can also be called a slotted antenna. Generally, the slot shape of the slot antenna is elongated. Based on the strong directivity of the slot antenna, the signal transmission and / or reception area formed by the slot antenna is also relatively flat due to the constraint of its slot shape.

[0081] To improve the WIFI signal transmission and reception performance of the interactive tablet, the signal transmission and reception direction of the first antenna 321 is set to face the front of the interactive tablet in this example. That is, the slot antenna is located on the rear side of the back plate 20 and is directly opposite the back plate 20. As can be seen from the above embodiment, in order to ensure the structural strength of the interactive tablet, the back plate 20 can be made of metal and processed by sheet metal technology. In order to avoid the metal back plate 20 from interfering with the first antenna 321, a first clearance hole 21 is provided on the back plate 20 opposite to the slot antenna so that the first antenna 321 can transmit and receive radio frequency signals through the first clearance hole 21.

[0082] Please continue to refer to this. Figures 3-8 In the embodiment where the antenna assembly 30 is fixed to the frame body 10 by the antenna bracket 40, in order to adapt to the structure of the dielectric substrate 31, the antenna bracket 40, in addition to being installed and mated with the frame body 10, also needs to have one side of its structure extending to the rear side of the back plate 20. In this embodiment, because the antenna assembly 30 is relatively light, the antenna bracket 40 can be made of plastic, which is relatively light and has weaker structural strength than metal. In the case where the antenna bracket 40 is made of plastic, since plastic is an insulating material, even if the antenna bracket 40 is located between the back plate 20 and the first antenna 321, the antenna bracket 40 will not interfere with the first antenna 321. By using a plastic antenna bracket 40, not only is the problem of fixing the antenna assembly 30 on the frame body 10 solved, but interference with the first antenna 321 is also avoided.

[0083] As described in the above embodiments, the screen 60 is located on the front side of the back panel 20. In one embodiment, the screen 60 includes a display area 61 and a black border area 62 formed around the display area 61. The black border area 62 can be an area formed by ink screen printing on the back side of the glass panel. It is used to shield electronic components located at the edge of the screen 60 and to prevent the backlight module from leaking light at the edge of the screen 60. On this basis, the first antenna 321 is set directly opposite the black border area 62 of the screen 60. In this way, in addition to avoiding the first antenna 321 from being exposed from the display area 61 of the screen 60 and affecting the overall visual effect of the interactive flat panel, it can also avoid interference from components such as the liquid crystal panel set in the display area 61 to the first antenna 321.

[0084] With the above configuration, when the first clearance hole 21 is provided on the back panel 20, the front side of the first antenna 321 has a sufficient clearance area, so that it can transmit and / or receive signals through the antenna bracket 40 and the screen 60. In addition to meeting the functional requirements of the antenna assembly 30, it also ensures that the antenna assembly 30 will not be exposed from the front and outside of the interactive tablet, and avoids the situation of opening through holes on the front side of the frame body 10, ensuring that the interactive tablet has a high overall visual effect.

[0085] As an implementation that can be independent of the aforementioned slot antenna, or incorporated into the aforementioned implementation of the slot antenna scheme, in this implementation, the second unit is a steel sheet antenna. The block-shaped portions located on the front and rear sides of the dielectric substrate 31 in the figure are schematic models of the signal transmission and reception areas of the steel sheet antenna, which can also be understood as schematic models of the clearance areas on the front and rear sides of the steel sheet antenna. The steel sheet antenna can be formed by stamping, which has the advantage of making full use of various irregular surfaces in three-dimensional space and reducing the size of the antenna. Since the directivity of the steel sheet antenna is relatively weak, it can be set on the front or rear side of the dielectric substrate 31. In this example, the steel sheet antenna is located on the rear side of the frame body 10.

[0086] In the above structure, since the antenna assembly 30 is externally located on the rear side of the frame body 10, the interactive flat panel has clearance areas on the upper, lower, and rear sides of the second antenna 322. To accommodate the characteristic that a clearance area needs to be formed within a certain area around the steel sheet antenna, such as... Figures 4-5 As shown, a hollow cavity is formed inside the frame body 10. In the embodiment where the frame body 10 is a profile frame, the cavity is the accommodating space inside the profile frame. A second clearance hole 15 communicating with the cavity is provided at the position of the mounting part 11 opposite to the steel sheet antenna, so that the front side of the second antenna 322 can form a clear area with the cavity formed by the frame body 10 through the second clearance hole 15.

[0087] According to the above implementation, the upper, lower and rear sides of the second antenna 322, which is a steel sheet antenna, are not blocked or interfered with by other structural components of the interactive flat plate. The front side of the second antenna 322 can form a clear area through the second clearance hole 15 and the cavity. Although the cavity distance between the second antenna 322 and the antenna body is small, it is enough to meet the characteristics of the steel sheet antenna, so that the second antenna 322 can normally provide the corresponding signal reception and / or transmission functions.

[0088] According to any of the above embodiments, since the antenna assembly 30 of this solution is externally mounted on the frame body 10, its upper, lower, and rear sides are exposed to the outside of the interactive flat panel when it is installed on the frame body 10. To provide appropriate protection for the antenna assembly 30, such as... Figures 1-5 As shown, the interactive flat panel also includes an antenna cover plate 50, which covers the rear side of the frame body 10. When the antenna cover plate 50 is installed on the frame body 10, a hollow protective cavity is formed between the antenna cover plate 50 and the frame body 10, or between the antenna cover plate 50 and the frame body 10 and the back plate 20, to provide an installation position for the antenna assembly 30. Whether the antenna cover plate 50 forms a protective cavity only with the frame body 10 or between the frame body 10 and the back plate 20 depends on whether the antenna assembly 30 is only located on the rear side of the frame body 10 or on the rear side of the frame body 10 and the back plate 20.

[0089] In an embodiment where the antenna assembly 30 is only disposed on the rear side of the frame body 10, the antenna cover 50 is disposed on at least a portion of the rear side of the frame body 10, and the antenna cover 50 cooperates with the frame body 10 to surround the periphery of the antenna assembly 30; while in an embodiment where the antenna assembly 30 is disposed on the rear side of both the frame body 10 and the back plate 20, the antenna cover 50 is disposed on at least a portion of the rear side of both the frame body 10 and the back plate 20, and the antenna cover 50 cooperates with the frame body 10 and the back plate 20 to surround the periphery of the antenna assembly 30.

[0090] To prevent the antenna cover 50 from interfering with the antenna assembly 30, a clearance gap 51 is formed between the antenna cover 50 and the antenna assembly 30 to ensure sufficient clearance area between them, meeting the functional requirements of the antenna assembly 30. Furthermore, the antenna cover 50 must be made of a material without signal shielding capabilities (such as plastic) to avoid shielding or interfering with the signal of the antenna assembly 30 when it is placed over the antenna assembly 30.

[0091] In summary, this embodiment places the antenna assembly 30 externally on the rear side of the frame body 10, so as to avoid setting a clearance hole on the front side (the appearance surface of the interactive flat panel) of the frame body 10 while meeting the functional requirements of the antenna assembly 30. This achieves the purpose of improving the structural strength of the frame body 10 and even the entire interactive flat panel, as well as the overall visual effect of the product. Furthermore, it allows the interactive flat panel to continue the concept of narrow bezel design and meet the usage needs of different user groups.
