Description

Technical Field

[0001] This disclosure relates to the technical field of display devices, and in particular to an interactive flat panel and a connecting bracket. Background Technology

[0002] In the relevant technology, the top frame, two side frames and the back panel are integrally formed, and the back panel is connected to the back of the bottom frame through a connecting bracket.

[0003] However, when there are assembly tolerances, production deviations, or slight deformations in the lower bezel, connecting bracket, and back panel body, this connection method can result in a large splicing gap and discontinuity between the front of the lower bezel and the front of the side bezel, affecting the overall aesthetics of the interactive flat panel. Summary of the Invention

[0004] The purpose of this disclosure is to provide an interactive flat panel and a connecting bracket that can reduce the splicing gap and discontinuity between the bottom edge and the side edge on the front, thereby improving the aesthetics of the interactive flat panel.

[0005] According to one aspect of this disclosure, an interactive flat panel is provided, the interactive flat panel including at least a back panel, a first frame, a connecting bracket, and a protrusion, wherein the back panel includes a back panel body and a second frame, the back panel body and the second frame being an integral structure; the back side of the first frame is connected to the back panel body via the connecting bracket; the protrusion is sandwiched between the front side of the back panel body and the connecting bracket, and is perpendicular to the length direction of the first frame, the protrusion being located between the connection area of ​​the back panel body and the connecting bracket and the connection area of ​​the first frame and the connecting bracket, such that during the connection of the connecting bracket to the back panel body, the connecting bracket may rotate around the protrusion or have a tendency to rotate around the protrusion.

[0006] The technical solution provided in this disclosure, by integrating the back panel body and the second frame into an integrated structure, not only reduces the number of parts that need to be assembled in the interactive flat panel, simplifies the assembly process, reduces production costs, and facilitates quality control, but also reduces splicing gaps and improves aesthetics.

[0007] Furthermore, by connecting the back of the first frame to the back panel body via a connecting bracket, this disclosure addresses the issue of side frame deformation caused by the connection between the first and second frames. By using the connecting bracket to connect the first frame to the back panel body, the high strength of the back panel body improves the connection stability and product qualification rate of the first frame. Simultaneously, the back panel body has a large forming space, and the strength of the connection between the back panel body and the connecting bracket can be further improved by stamping and bending the portion of the back panel body used for connecting with the connecting bracket. On the other hand, a locking operation is performed on the back of the interactive flat panel, with the locking operation located outside the first frame for convenient operation.

[0008] Furthermore, a protrusion is positioned perpendicular to the length of the first frame at the connection area between the connecting bracket and the back panel body, and between the connecting bracket and the first frame. During the connection of the connecting bracket to the back panel body, the connecting bracket rotates or tends to rotate around the protrusion, causing the end of the connecting bracket connected to the first frame to rotate or tend to rotate towards the front. This, in turn, causes the first frame to rotate or tend to rotate towards the front, creating a closing force between the front of the first frame and the front of the side frame. This closing force helps to overcome assembly tolerances, production deviations, or slight deformations, reducing the gap and / or discontinuity between the front of the first frame and the front of the side frame, thus improving aesthetics and product yield.

[0009] Optionally, the protrusion is connected to the back of the connecting bracket, and the protrusion abuts against the front of the back plate body.

[0010] Using the above method, the protrusion can be installed together with the connecting bracket, simplifying the installation process.

[0011] Optionally, the connecting bracket includes a first connecting segment and a second connecting segment connected to the first connecting segment, wherein the first connecting segment is connected to the back panel body, the second connecting segment is connected to the first frame, and the strength of the second connecting segment is greater than the strength of the first connecting segment.

[0012] With the above solution, the strength of the second connecting segment can be greater than that of the first connecting segment, reducing the possibility of the second connecting segment breaking or bending under pressure or tension, so as to ensure the connection stability between the lower frame and the back panel body connected by the second connecting segment.

[0013] Optionally, the protrusion is disposed on the first connecting segment.

[0014] The above solution allows more of the first connecting segment to remain on the backplate body, thereby improving the reliability of the connection between the connecting bracket and the backplate body.

[0015] Optionally, the first connecting segment and the second connecting segment are formed into one piece using a die-casting process.

[0016] The above solution simplifies the production process. At the same time, the first and second connecting sections can be injection molded to meet high precision requirements.

[0017] Optionally, along the front to back direction of the interactive flat panel, the first connecting segment and the second connecting segment have overlapping areas; at least one first fastener passes through the second connecting hole of the first connecting segment, the second connecting segment and the first connecting hole of the back panel body to connect the first connecting segment, the second connecting segment and the back panel body.

[0018] Through the above solution, the second connecting segment can not only be fixed to the back panel body via the first connecting segment, but also directly fixed to the back panel body via the first fastener, further improving the connection stability between the lower frame and the back panel body. Simultaneously, the direct connection of the second connecting segment to the back panel body can also share the connection stress between the first and second connecting segments, reducing the possibility of breakage due to excessive stress on the first connecting segment and improving its service life.

[0019] Optionally, the protrusion is connected to the front of the back plate body, and the protrusion abuts against the back of the connecting bracket.

[0020] Using the above method, the protrusion can be installed together with the main body of the back panel, simplifying the installation process.

[0021] Optionally, the first frame is a bottom frame, and the second frame includes a top frame and two side frames; when the bottom frame is connected to the back panel body through the two connecting brackets, the bottom frame, the top frame, and the two side frames form a quadrilateral frame structure surrounding the back panel body.

[0022] With the above solution, the bottom frame is used as the first frame, meaning that the bottom frame is formed separately, which makes it easier to form corresponding port holes and speaker holes on the bottom frame, simplifying the processing steps.

[0023] Optionally, there are two connecting brackets, which are symmetrically arranged at opposite ends along the length of the lower frame.

[0024] With the above solution, both ends of the lower frame are connected to the back panel body via connecting brackets, which improves the connection stability of the connecting brackets. Furthermore, it ensures that the force is evenly distributed at both ends of the connecting brackets, avoiding the possibility of damage caused by uneven force distribution.

[0025] Optionally, the front of the back panel body is provided with a mounting groove that bends and recesses towards the back, and the connecting bracket portion is located in the mounting groove and connected to the back panel body.

[0026] The above solution improves the strength of the connection between the back panel and the connecting bracket by bending the back panel body, thereby enhancing the installation stability of the lower frame connected to the connecting bracket.

[0027] Optionally, the bottom of the mounting groove is provided with a first positioning hole and a first connecting hole; the connecting bracket is provided with a first positioning pin corresponding to the first positioning hole and a second connecting hole corresponding to the first connecting hole, so that the first positioning pin is inserted into the first positioning hole, and the first fastener connects the connecting bracket to the back plate body through the first connecting hole and the second connecting hole.

[0028] The above method allows for the positioning of the connecting bracket before locking and connecting, improving installation efficiency.

[0029] Optionally, the front of the connecting bracket is provided with a slot, the slot is located in the area formed by the side frame, and the slot surface is provided with a first limiting part at one end near the lower frame.

[0030] The above solution also allows the connecting bracket to limit the light filter strip within the side frame, eliminating the need for additional components to limit the light filter strip within the side frame. This simplifies the number of components in the interactive flat panel, improves assembly efficiency, and reduces costs.

[0031] Optionally, the interactive flat panel further includes a protective panel, and the front of the connecting bracket is provided with a support portion; along the front of the interactive flat panel pointing to the back, the protective panel is constrained between the support portion and the filter strip located within the side frame, and / or, the protective panel is constrained between the support portion and the filter strip located within the lower frame.

[0032] The above solution also allows the connecting bracket to support and limit the protective panel, eliminating the need for additional components to support and limit the protective panel. This simplifies the number of components in the interactive flat panel, improves assembly efficiency, and reduces costs.

[0033] Optionally, the connecting bracket further includes a side plate portion, which is connected to the end of the lower frame.

[0034] With the above solution, when assembling the bottom frame with the rest of the interactive panel, the side of the connecting bracket can be pre-fixed to the end of the bottom frame to prevent the bottom frame from falling off during the process of flipping the interactive panel to the back facing up. Then, the connecting bracket on the back is locked to the bottom frame, which facilitates the assembly operation.

[0035] According to another aspect of this disclosure, a connecting bracket is also provided, the connecting bracket including a first connecting segment and a second connecting segment, the first connecting segment and the second connecting segment being integrally formed by a die-cutting process, wherein the back of the first connecting segment is provided with a protrusion, and the back of the first connecting segment is provided with a first positioning pin and / or a second connecting hole; the front of the second connecting segment is provided with a second positioning pin and / or a fourth connecting hole; wherein the protrusion is closer to the second connecting segment than the first positioning pin and the second connecting hole.

[0036] Optionally, the strength of the second connecting segment is greater than that of the first connecting segment; and / or, the first connecting segment is made of plastic and the second connecting segment is made of metal; and / or, the second connecting segment has a connecting hole coaxially arranged with the second connecting hole; and / or, the front of the first connecting segment is provided with a slot, and the slot surface of the slot is provided with a first limiting part near one end of the second connecting segment; and / or, the front of the first connecting segment is provided with a support part.

[0037] According to another aspect of this disclosure, an interactive flat panel is also provided, the interactive flat panel including a back panel body, a first frame and a protrusion, wherein the back side of the first frame is connected to the back panel body via a connecting bracket; the protrusion is clamped between the front side of the back panel body and the connecting bracket, and is located in a direction perpendicular to the length direction of the first frame, the protrusion being located between the connection area of ​​the back panel body and the connecting bracket and the connection area of ​​the first frame and the connecting bracket, such that during the connection of the connecting bracket to the back panel body, the connecting bracket rotates around the protrusion or has a tendency to rotate around the protrusion.

[0058] The outer shell of an interactive flat panel typically consists of a back panel and four side frames mounted around it. The side frames are connected to the back panel using screws, and adjacent side frames are connected by screws at their inner corners. The outer shell of an interactive flat panel has many parts, and the back panel and side frames require multiple connection operations, leading to an overly complex assembly process, difficulty in controlling seam gaps, and increased manufacturing costs. Furthermore, the outer shell of an interactive flat panel has multiple splicing areas, or rather, multiple seams, which seriously affect the aesthetics of the interactive flat panel.

[0059] To address this, this disclosure attempted to integrally mold the top frame and two side frames with the back panel body. Specifically, the top frame and two side frames were stamped from a single sheet of material, and their outer perimeter was plastically deformed to form the frame. This not only reduced the number of parts and simplified the assembly process but also reduced the gap between the frame and the back panel, improving aesthetics. However, because the two side frames were formed by plastic deformation of the outer perimeter of the sheet material, their strength was lower than that of side frames extruded from original aluminum. If, after integrally molding the top frame and two side frames with the back panel body, the bottom frame was still connected to the two side frames using internal corner pieces, it would easily lead to tensile deformation of the side frames, reducing the product yield.

[0060] Based on this, considering that the strength of the back panel body in the unibody molding scheme is higher than that of the side frame, and it is less prone to tensile deformation, this disclosure uses a connecting bracket to connect the lower frame to the back panel body. This utilizes the strength of the back panel body to improve the connection stability and product qualification rate of the lower frame. Simultaneously, the back panel body has a large molding space, and the strength of the connection between the back panel body and the connecting bracket can be further improved by stamping and bending the connection portion. Furthermore, by connecting the connecting bracket to the back of the lower frame, the connection operation between the connecting bracket and the lower frame is moved to the outside, obtaining more operating space and facilitating installation.

[0061] However, this also leads to a lack of connection and tension between the front of the bottom bezel and the front of the side bezel. When there are assembly tolerances, production deviations, or slight deformations in the components that work together, there will be a large gap and / or discontinuity between the front of the bottom bezel and the front of the side bezel, affecting the aesthetics of the interactive flat panel.

[0062] Therefore, this disclosure further provides a protrusion between the connecting bracket and the back plate body, and the protrusion is located between the connection area between the connecting bracket and the back plate body and the connection area between the connecting bracket and the lower frame. When the connecting bracket is connected to the back plate body, the connecting bracket rotates around the protrusion or has a tendency to rotate, so that there is a mutual approaching and closing force between the front of the lower frame and the front of the side frame. Thus, when there are assembly tolerances, production deviations or slight deformations, the mutual approaching and closing force can overcome the above problems as much as possible, reduce the gap and / or discontinuity between the front of the lower frame and the front of the side frame, and improve the aesthetics and product yield.

[0063] In addition, the connecting bracket can also integrate the filter strip limiting structure in the lower frame and the support structure of the protective panel, simplifying the number of parts and reducing production costs.

[0064] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this disclosure, but not all embodiments.

[0065] This disclosure provides an interactive flat panel that integrates infrared touch control and display functions. Specifically, the infrared touch control function utilizes touch components installed on the edge of the interactive flat panel. These components emit and receive infrared rays, forming an infrared detection network on the screen surface. When any object touches the screen, it alters the infrared light at the touch point, thereby enabling touchscreen operation. It should be noted that the interactive flat panel involved in this disclosure may include, but is not limited to, various interactive flat panels such as commercial displays, conference displays, touch all-in-one machines, self-service terminals, human-computer interaction flat panels, televisions, and smart blackboards.

[0066] Please see also Figures 1 to 3 As shown, the interactive flat panel may include at least a back panel 100, a first frame, and at least one connecting bracket 300. The back panel 100 serves as the main supporting component of the interactive flat panel, primarily supporting and protecting other components within the panel. Simultaneously, the back panel 100 covers the outer surface of the interactive flat panel, serving at least partially as an exterior component. Specifically, the back panel 100 includes a back panel body 110 and a second frame, which are integrally formed, or in other words, the back panel body 110 and the second frame are integrally molded, with the second frame surrounding the outer side of the back panel body 110. This not only reduces the number of components required for assembly, simplifies the assembly process, lowers production costs, and facilitates quality control, but also reduces splicing gaps and improves aesthetics.

[0067] The first frame is connected to the back plate body 110 via at least one connecting bracket 300. This addresses the issue of the lower frame 200 being prone to tensile deformation when connected to the side frame 130, as is common with the connection between the side frame 130 and the lower frame 200. By using the connecting bracket 300 to connect the first frame to the back plate body 110, the high strength of the back plate body 110 improves the connection stability and product qualification rate of the first frame. Furthermore, the back plate body 110 has a large forming space, and the strength of the connection between the back plate body 110 and the connecting bracket 300 can be further improved by stamping and bending the portion of the back plate body 110 used for connecting with the connecting bracket 300.

[0068] For example, such as Figure 3 and Figure 4 As shown, the front of the back panel body 110 is provided with a mounting groove 111 that bends and recesses towards its back side. The connecting bracket 300 is located in the mounting groove 111 and connected to the back panel body 110. By bending the back panel body 110, the strength of the connection between the back panel body 110 and the connecting bracket 300 is increased, thereby improving the installation stability of the first frame connected to the connecting bracket 300.

[0069] Regarding the specific connection structure between the connecting bracket 300 and the back plate body 110, in some embodiments, such as Figure 3 and Figure 5 As shown, the bottom of the mounting groove 111 may be provided with a first positioning hole 112 and a first connecting hole 113. Correspondingly, the connecting bracket 300 is provided with a first positioning pin 310 corresponding to the first positioning hole 112 and a second connecting hole 320 corresponding to the first connecting hole 113. This allows for positioning during assembly by first inserting the first positioning pin 310 into the first positioning hole 112, aligning the first connecting hole 113 with the second connecting hole 320, and then using a first fastener to connect the connecting bracket 300 to the back plate body 110 through the first connecting hole 113 and the second connecting hole 320. This allows for positioning before fastening, improving installation efficiency.

[0070] For example, the number of the first positioning hole 112, the first connecting hole 113, the second connecting hole 320, and the first positioning pin 310 can all be one or more. At least one of the first connecting hole 113 and the second connecting hole 320 can be a threaded hole, and correspondingly, the first fastener can be a screw, which connects the connecting bracket 300 to the back plate body 110 through the threaded connection of the screw to one or both of the first connecting hole 113 and the second connecting hole 320; the first connecting hole 113 and the second connecting hole 320 can both be through-hole structures, and correspondingly, the first fastener can be a bolt assembly, with the screw passing through the first connecting hole 113 and the second connecting hole 320 and connecting to the nut.

[0071] In some other embodiments, the connection point between the connecting bracket 300 and the back plate body 110 may also be provided with multiple first connecting holes 113 and second connecting holes 320, without the need to provide the first positioning pin 310 and the first positioning hole 112.

[0072] In some embodiments, the connecting bracket 300 may be one, and the connecting bracket 300 may extend along the length direction of the first frame to increase the connection area between the connecting bracket 300 and the first frame and the back plate body 110, thereby improving the connection stability of the first frame.

[0073] In some other embodiments, please refer again. Figure 2 As shown, there may be two connecting brackets 300. The first frame can be connected to the back plate body 110 through the two connecting brackets 300, and the two connecting brackets 300 are arranged adjacent to the opposite ends of the first frame along its length. In this way, the two ends of the first frame are connected to the back plate body 110 through the connecting brackets 300 respectively, which can improve the connection stability of the first frame. Furthermore, it can ensure that the two ends of the connecting brackets 300 are subjected to uniform force, avoiding the possibility of damage caused by uneven force at both ends.

[0074] In some embodiments, the connecting bracket 300 is connected to the front or back of the back panel body 110 to increase the connection area between the connecting bracket 300 and the back panel body 110, thereby improving the connection reliability. Simultaneously, the connection direction of the connecting bracket 300 is approximately perpendicular to the back panel body 110 for ease of connection. It should be noted that when the interactive flat panel is in normal use, or when it is suspended on a wall, the side facing the user is the front of the various components of the interactive flat panel, and vice versa.

[0075] Preferably, the connecting bracket 300 is located on the front of the back panel body 110, so that in addition to connecting the back panel body 110 and the lower frame 200, the connecting bracket 300 can also participate in other functions of the interactive flat panel, such as limiting the filter strip or supporting and protecting the panel.

[0076] The first border can be one of the bottom border 200, the top border 120, and the two side borders 130; the second border can be any other than the first border, and there is at least one border adjacent to the first border.

[0077] In some embodiments, such as Figures 1 to 3 As shown, the first frame is the lower frame 200, and the second frame includes the upper frame 120 and two side frames 130. When the lower frame 200 is connected to the back panel body 110 through two connecting brackets 300, the lower frame 200, the upper frame 120 and the two side frames 130 form a quadrilateral frame structure around the back panel body 110.

[0078] For example, the lower border 200 is parallel to and opposite to the upper border 120, and the two side borders 130 are located at opposite ends of the lower border 200, so that the lower border 200, the upper border 120, and the two side borders 130 form a rectangular structure. The integral molding method of the back panel body 110, the upper border 120, and the two side borders 130 can be 3D printing, casting, injection molding, and plastic deformation, etc. Taking the integral molding of the back panel body 110, the upper border 120, and the two side borders 130 by plastic deformation as an example, the upper border 120 and the two side borders 130 are plastically deformed from the periphery of the back panel body 110. The back panel body 110 covers the back of the interactive flat panel, and the upper border 120 and the two side borders 130 cover part of the sides and part of the front edge of the interactive flat panel.

[0079] For ease of understanding, the following description will use the example of the first border being the bottom border 200, and the second border including the top border 120 and two side borders 130.

[0080] Taking the connecting bracket 300 as an example, which can also limit the position of the filter strip 400 within the side frame 130, such as Figure 4 , Figure 6 and Figure 7 As shown, the front of the connecting bracket 300 may be provided with a slot 330, which is located in the area formed by the side frame 130. A first limiting part 340 is provided at one end of the slot surface near the lower frame 200. During installation, the connecting bracket 300 can be pre-installed on the back panel body 110. Then, the filter strip 400 of the side frame 130 is inserted into the side frame 130 from the corner opening on the top side and pushed towards the ground side until the filter strip 400 is inserted into the slot 330 and abuts against the first limiting part 340, thus determining the final installation position. Simultaneously, the two sides of the slot 330 can also limit the left and right sides of the filter strip within the side frame 130, thereby ensuring the accurate installation position of the filter strip 400 within the side frame 130 and improving infrared detection accuracy. In this way, the connecting bracket 300 can also limit the light filter strip 400 inside the side frame 130, eliminating the need for additional components to limit the light filter strip 400 inside the side frame 130, simplifying the number of components in the interactive flat panel, improving assembly efficiency and reducing costs.

[0081] For example, the first limiting part 340 may be provided on the bottom and / or side of the groove of the connecting bracket 300.

[0082] Taking the connecting bracket 300 as an example, which can also support the protective panel 500, for instance... Figure 7 and Figure 8As shown, the interactive flat panel also includes a protective panel 500, and a support portion 350 is provided on the front side of the connecting bracket 300. Along the direction from the front to the back of the interactive flat panel, the protective panel 500 is constrained between the support portion 350 and a light filter strip 400 located within the side frame 130, and / or, the protective panel 500 is constrained between the support portion 350 and the light filter strip 400 located within the lower frame 200. Alternatively, the front of the protective panel 500 abuts against the light filter strip 400, and the back of the protective panel 500 abuts against the support portion 350, thereby limiting the front and back of the protective panel 500. In this way, the connecting bracket 300 can also support and limit the protective panel 500, eliminating the need for additional components to support and limit the protective panel 500, simplifying the number of components in the interactive flat panel, improving assembly efficiency, and reducing costs.

[0083] For example, the support portion 350 can be constructed as a straight rod structure and disposed adjacent to the lower frame 200 or the side frame 130. The support portion 350 can also be constructed as an L-shaped structure, with one end of the support portion 350 disposed adjacent to the lower frame 200 and the other end of the support portion 350 disposed adjacent to the side frame 130.

[0084] Regarding the connection position between the connecting bracket 300 and the lower frame 200, this disclosure provides two feasible embodiments for reference.

[0085] In the first embodiment, the connecting bracket 300 is located on the top side of the lower frame 200, or in other words, the connecting bracket 300 is connected to the side of the lower frame 200 adjacent to the upper frame 120. During installation, the fastener needs to pass through the lower frame 200 from the bottom side and perform a locking operation inside the lower frame 200.

[0086] In the second embodiment, the connecting bracket 300 is located on the back of the lower frame 200, or in other words, the connecting bracket 300 is connected to the back of the lower frame 200. Thus, compared to the top-side connection method of the connecting bracket 300 and the lower frame 200, this embodiment allows the connecting bracket 300 and the lower frame 200 to be locked on the back of the interactive flat panel. The locking operation is located on the outside of the lower frame 200, which is convenient for operation.

[0087] Regarding the specific connection structure between the lower frame 200 and the connecting bracket 300, in some embodiments, such as Figure 7 , Figure 9 and Figure 10As shown, the back of the lower frame 200 is also provided with a second positioning hole and a third connecting hole. Correspondingly, the connecting bracket 300 is provided with a second positioning pin 360 corresponding to the second positioning hole and a fourth connecting hole 370 corresponding to the third connecting hole. This allows for positioning during assembly by first inserting the second positioning pin 360 into the second positioning hole, aligning the third connecting hole and the fourth connecting hole 370, and then using a second fastener to connect the connecting bracket 300 to the lower frame 200 through the third connecting hole and the fourth connecting hole 370. This allows for positioning before fastening, improving installation efficiency.

[0088] For example, the number of the second positioning hole, the third connecting hole, the second positioning pin 360, and the fourth connecting hole 370 can all be one or more. At least one of the third connecting hole and the fourth connecting hole 370 can be a threaded hole, and correspondingly, the second fastener can be a screw, which connects the connecting bracket 300 to the lower frame 200 by threading one or both of the third connecting hole and the fourth connecting hole 370; the third connecting hole and the fourth connecting hole 370 can both be through holes, and correspondingly, the first fastener can be a bolt assembly, with the screw passing through the third connecting hole and the fourth connecting hole 370 and connecting to the nut.

[0089] Considering that during the assembly process of the lower frame 200, when assembling the lower frame 200 with the rest of the interactive flat panel (the whole formed by the back panel 100, display module, and protective panel 500), the other components of the interactive flat panel are in a front-facing state, while the locking area between the connecting bracket 300 and the lower frame 200 is located on the back of the lower frame 200, making locking impossible, in some embodiments, the connecting bracket 300 further includes a side plate portion 380 for connecting to the end of the lower frame 200. Thus, when assembling the lower frame 200 with the rest of the interactive flat panel, the side plate portion 380 of the connecting bracket 300 can be pre-fixed to the end of the lower frame 200 to prevent the lower frame 200 from detaching during the process of flipping the interactive flat panel to the back-facing position, and then the locking operation between the connecting bracket 300 and the lower frame 200 on the back can be performed.

[0090] Regarding the specific structure of the connecting bracket 300, as follows: Figure 4 and Figure 5 ,as well as Figure 7 and Figure 9As shown, the connecting bracket 300 may include a first connecting segment 301 and a second connecting segment 302 connected to the first connecting segment 301. The first connecting segment 301 is used to connect to the back panel body 110. Accordingly, the aforementioned first positioning pin 310, second connecting hole 320, slot 330, first limiting part 340, and support part 350 are all formed on the first connecting segment 301. The second connecting segment 302 is used to connect to the lower frame 200. Accordingly, the aforementioned second positioning pin 360, fourth connecting hole 370, and side plate part 380 are formed on the second connecting segment 302.

[0091] In some embodiments, the strength of the first connecting segment 301 and the second connecting segment 302 can be kept consistent.

[0092] In some other embodiments, the strength of the second connecting segment 302 may be greater than that of the first connecting segment 301, reducing the possibility of the second connecting segment 302 breaking or bending under pressure or tension, so as to ensure the reliability of the connection between the lower frame 200 and the back panel body 110 connected by the second connecting segment 302.

[0093] Optionally, the first connecting segment 301 and the second connecting segment 302 can be formed by two-color injection molding, controlling the strength variation of the first connecting segment 301 and the second connecting segment 302 by controlling the different materials used in each injection. The first connecting segment 301 and the second connecting segment 302 can also be formed into one piece by overmolding. In this way, at least one of the first connecting segment 301 and the second connecting segment 302 can be made of a non-plastic material. For example, the second connecting segment 302 can be made of metal, such as SECC (galvanized steel sheet). Correspondingly, the side plate portion 380 can be formed by bending. The first connecting segment 301 can be made of plastic material to facilitate the formation of the first positioning pin 310, the second connecting hole 320, the slot 330, the first limiting portion 340, and the support portion 350 by injection molding, ensuring high precision requirements.

[0094] Furthermore, along the front-to-back direction of the interactive flat panel, the first connecting segment 301 and the second connecting segment 302 have an overlapping area. At least one first fastener passes through the second connecting hole 320 of the first connecting segment 301, the second connecting segment 302, and the first connecting hole 113 of the back panel body 110, thereby connecting the first connecting segment 301, the second connecting segment 302, and the back panel body 110. In this way, the second connecting segment 302 can not only be fixed to the back panel body 110 via the first connecting segment 301, but also directly fixed to the back panel body 110 via the first fastener, further improving the connection stability between the lower frame 200 and the back panel body 110. Simultaneously, the direct connection of the second connecting segment 302 to the back panel body 110 can also share the connection stress between the first connecting segment 301 and the second connecting segment 302, reducing the possibility of the first connecting segment 301 breaking due to excessive stress and improving its service life.

[0095] In some embodiments, such as Figure 10 and Figure 11 As shown, the interactive flat panel also includes a corner piece 600, which covers the end opening of the lower frame 200 and smoothly connects with the appearance surface of the side frame 130 of the lower frame 200 to ensure the aesthetics of the interactive flat panel.

[0096] Furthermore, the corner piece 600 is provided with a second limiting part 610. When the corner piece 600 is installed on the end opening of the lower frame 200, the second limiting part 610 can abut against and limit the end of the filter strip 400 inside the lower frame 200, so as to improve the accuracy of the installation position of the filter strip 400 inside the lower frame 200.

[0097] For example, the second limiting part 610 can be integrated with the corner piece 600 or designed separately. One end of the corner piece 600 adjacent to the side frame 130 may have a first insertion part 620, and the other end of the corner piece 600 may have a second insertion part 630. The length of the first insertion part 620 may be greater than that of the second insertion part 630. The first insertion part 620 is used to insert into the side frame 130, and the first insertion part 620 and the side frame 130 have sufficient contact area to minimize the splicing gap between the corner piece 600 and the side frame 130. The second insertion part 630 is used to insert into the lower frame 200, and the second insertion part 630 is provided with a buckle. Correspondingly, the lower frame 200 is provided with a slot, thereby fixing the corner piece 600 by the engagement of the buckle and the slot.

[0098] Furthermore, the back of the corner piece 600 may also be provided with connecting holes, and the corner piece 600 may also be fixed to the lower frame 200 or the back plate body 110 through the connecting holes, so as to further improve the installation stability of the corner piece 600.

[0099] Considering that when the second connecting segment 302 is connected to the back of the lower frame 200, there is no connecting tension between the front of the lower frame 200 and the front of the side frame 130, when there are assembly tolerances, production deviations or slight deformations, there will be a large gap and / or discontinuity between the front of the lower frame 200 and the front of the side frame 130, which will affect the aesthetics of the interactive flat panel.

[0100] Therefore, in some embodiments, such as Figure 1 , Figure 5 and Figure 12 As shown, a protrusion 390 can be clamped between the connecting bracket 300 and the back plate body 110, and is perpendicular to the length direction of the lower frame 200 (e.g., Figure 12 In the direction of center (b), or in other words, along the direction from the top to the bottom of the interactive flat panel, the protrusion 390 is located between the connection area between the connecting bracket 300 and the back panel body 110 and the connection area between the connecting bracket 300 and the lower frame 200. Thus, during the connection of the connecting bracket 300 to the back panel body 110, the connecting bracket 300 rotates around the protrusion 390 or has a tendency to rotate, so that the end of the connecting bracket 300 connected to the lower frame 200 rotates towards the front (e.g., ...). Figure 12 The center direction a) or has a tendency to flip, thereby causing the lower frame 200 to flip to the front or has a tendency to flip, so that there is a mutual approaching and closing force between the front of the lower frame 200 and the front of the side frame 130. In this way, when there are assembly tolerances, production deviations or slight deformations, the mutual approaching and closing force can overcome the above problems as much as possible, reduce the gap and / or discontinuity between the front of the lower frame 200 and the front of the side frame 130, and improve the aesthetics and product yield.

[0101] It should be noted that the connection area defined in this disclosure can be understood as the area formed or composed of the corresponding fasteners. For example, when the connecting bracket 300 is connected to the back plate body 110 and the lower frame 200 respectively by a fastener, the area formed by the fastener connected to the back plate body 110 is the connection area between the connecting bracket 300 and the back plate body 110, and the area formed by the fastener connected to the lower frame 200 is the connection area between the connecting bracket 300 and the lower frame 200. When the connecting bracket 300 is connected to the back plate body 110 and the lower frame 200 respectively by a plurality of fasteners, the area formed by the plurality of fasteners connected to the back plate body 110 (which completely covers the plurality of fasteners) is the connection area between the connecting bracket 300 and the back plate body 110, and the area formed by the plurality of fasteners connected to the lower frame 200 (which completely covers the plurality of fasteners) is the connection area between the connecting bracket 300 and the lower frame 200.

[0102] Optionally, the protrusion 390 can be connected to the back of the connecting bracket 300, and the protrusion 390 abuts against the front of the back plate body 110. In this way, the protrusion 390 can be installed together with the connecting bracket 300, simplifying the installation process. For example, the protrusion 390 can be integrally formed with the connecting bracket 300, or it can be formed separately and then connected to each other.

[0103] The protrusion 390 can be disposed on the first connecting section 301, so that more of the first connecting section 301 remains on the back plate body 110, thereby improving the connection stability between the connecting bracket 300 and the back plate body 110. The protrusion 390 can also be disposed on the second connecting section 302. It should be noted that when the protrusion 390 is disposed on the second connecting section 302, the protrusion 390 should protrude from the back of the first connecting section 301, or the back plate body 110 should protrude from the front at the position corresponding to the protrusion 390, so that the protrusion 390 can abut against the front of the back plate body 110.

[0104] The protrusion 390 can also be connected to the front of the back panel body 110, abutting against the back of the connecting bracket 300, or the protrusion 390 can be a separate part located between the front of the back panel 110 and the back of the connecting bracket 300. Furthermore, the same effect can be achieved if the protrusion 390 is located between the connection area between the connecting bracket 300 and the back panel body 110 and the connection area between the connecting bracket 300 and the lower frame 200, along the direction from the top to the bottom of the interactive flat panel, or in other words, along the direction from the top to the bottom of the interactive flat panel.

[0105] For example, the protrusion 390 can be constructed as a strip structure, and the protrusion 390 is arranged substantially parallel to the lower border 200. The protrusion 390 can also be a multi-point structure, and the lines connecting the multiple points in the multi-point structure are straight lines, and these straight lines are arranged substantially parallel to the lower border 200.

[0106] According to another aspect of this disclosure, a connecting bracket 300 is also provided, comprising a first connecting segment 301 and a second connecting segment 302. The first connecting segment 301 and the second connecting segment 302 are integrally formed using a die-casting process. The back of the first connecting segment 301 is provided with a protrusion 390, and a first positioning pin 310 and / or a second connecting hole 320 are provided on the back of the first connecting segment 301. The front of the second connecting segment 302 is provided with a second positioning pin 360 and / or a fourth connecting hole 370. The protrusion 390 is closer to the second connecting segment 302 than the first positioning pin 310 and the second connecting hole 320.

[0107] Furthermore, the strength of the second connecting segment 302 is greater than that of the first connecting segment 301; and / or, the first connecting segment 301 is made of plastic and the second connecting segment 302 is made of metal; and / or, the second connecting segment 302 has a connecting hole coaxially arranged with the second connecting hole 320; and / or, the front of the first connecting segment 301 is provided with a slot 330, and the groove surface of the slot 330 is provided with a first limiting part 340 near one end of the second connecting segment 302; and / or, the front of the first connecting segment 301 is provided with a support part 350.

[0108] It should be noted that the specific structure of the first connecting segment 301 and the second connecting segment 302 can be found in the detailed description in the above embodiments, and will not be repeated here.

[0109] According to another aspect of this disclosure, an interactive flat panel is also provided. The interactive flat panel includes a back panel body 110, a first frame, and a protrusion 390. The back side of the first frame is connected to the back panel body 110 via a connecting bracket 300. The protrusion 390 is sandwiched between the front side of the back panel body 110 and the connecting bracket 300, and is located in a direction perpendicular to the length direction of the first frame. The protrusion 390 is located between the connection area of ​​the back panel body 110 and the connecting bracket 300 and the connection area of ​​the first frame and the connecting bracket 300, so that during the connection process between the connecting bracket 300 and the back panel body 110, the connecting bracket 300 can rotate around the protrusion 390 or has a tendency to rotate around the protrusion 390.

[0110] It should be noted that the first border defined here can be any of the top border, bottom border, and side border. The back panel body 110 can be an independent integral structure, or it can form an integral structure with at least one of the other borders besides the aforementioned borders. For example, when the first border is the bottom border, the back panel body 110 can be an independent integral structure without forming an integral structure with the top border and side border. Alternatively, the back panel body 110 can form an integral structure with at least one of the top border and side borders. Furthermore, regarding the specific structure of the connection between the back panel body 110 and the border via the connecting bracket 300, please refer to the detailed description of the connection between the back panel body 110 and the bottom border 200 via the connecting bracket 300 in the foregoing embodiments; it will not be repeated here.
