Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a corner support and an interactive panel. BACKGROUND

[0002] In the related art, the frame and the back plate of some interactive panels are in a split structure, that is, the frame and the back plate are respectively processed and formed. In such an interactive panel, the corner support arranged at the corner position is mainly used to connect the frames of two adjacent sides of the interactive panel.

[0003] Since it is difficult to use the independent frame, the processing time is relatively long, and part of the edge of the back plate of some interactive panels is bent to process the frame structure in an integrated structure with the back plate. In this way, the number of split frames can be reduced to improve the processing efficiency and reduce the cost of the interactive panel. For example, some interactive panels only retain an independent upper frame assembly or a lower frame assembly, and the frame structures on the left and right sides are integrally formed on the back plate.

[0004] For the interactive panel integrally formed with the back plate, the corner structure used in the related art cannot be applied, and the function is relatively single, resulting in a large number of parts in the interactive panel. CONTENT OF THE UTILITY MODEL

[0005] The present application provides a corner support and an interactive panel, which aims to make the corner support applicable to the interactive panel integrally formed with the back plate, and expand the function of the corner support to reduce the number of parts in the interactive panel.

[0006] The specific technical solutions are as follows:

[0007] The embodiment of the first aspect of the present application provides a corner support for an interactive panel, the corner support comprising: a support body, the support body being provided with a connecting hole for connecting with a back plate of the interactive panel, the support body being further used for connecting with a frame assembly; and a plug-in part, the plug-in part being connected with the support body, the plug-in part being formed with a plug-in groove, the plug-in groove being used for limiting a touch assembly of the interactive panel; wherein the frame assembly and the touch assembly are arranged on adjacent sides of the interactive panel.

[0008] The corner support in the embodiment of the present application, wherein the support body is used to connect with the back plate of the interactive panel, and the support body is also used to connect with the frame assembly of the interactive panel, so that the frame assembly can be fixed to the back plate of the interactive panel through the support body, thereby realizing the installation and fixation of the frame assembly. In addition, the corner support also has a plug-in part connected with the support body, and one end of the touch assembly of the interactive panel can be plugged into the slot of the plug-in part, so that the touch assembly is limited through the slot. Therefore, the corner support has multiple functions, which can not only install and fix the frame assembly, but also limit the touch assembly of the adjacent side. In this way, it is not necessary to additionally set a structure specially used for limiting the touch assembly. The present application has multiple functions through the corner support, which is beneficial to reducing the number of parts in the interactive panel, thereby being beneficial to the cost optimization of the interactive panel.

[0009] In some embodiments, the touch assembly comprises a mounting frame and a touch circuit board, the mounting frame is provided with a receiving cavity, and the touch circuit board is arranged in the receiving cavity; the slot is used for limiting the mounting frame, and an abutting surface is formed in the slot and used for abutting against an end surface of one end of the mounting frame.

[0010] The slot is used for limiting the mounting frame, that is, the mounting frame of the touch assembly is plugged into the slot. On this basis, the abutting surface is arranged in the slot, and the abutting surface abuts against the end of one end of the mounting frame when the mounting frame is plugged into the slot. In this way, the abutting surface can also limit the mounting frame in the length direction of the mounting frame. Therefore, through the cooperation of the slot and the abutting surface, the mounting frame can be limited in different directions, so that the installation stability of the touch assembly can be effectively improved, and the working performance stability of the touch assembly can be ensured.

[0011] In some embodiments, the abutting surface is arranged obliquely relative to the length direction of the touch assembly.

[0012] The abutting surface is an inclined surface, which makes the abutting surface can be matched with the end inclined surface of the mounting frame, so that the abutting surface can have better stability when abutting against the end of the mounting frame.

[0013] In some embodiments, the support body is provided with a limiting protrusion, the limiting protrusion has a limiting surface, the limiting surface is arranged opposite to the slot, and the limiting surface is used for abutting against the end of the touch circuit board to limit the touch circuit board.

[0014] On the basis that the abutting surface abuts against the end of the mounting frame, thereby limiting the mounting frame along the length direction of the mounting frame, the end of the touch circuit board also abuts against the limiting surface of the limiting protrusion, so as to limit the touch circuit board along the length direction of the mounting frame. In this way, the corner support can limit the mounting frame of the touch assembly and the touch circuit board at the same time, thereby being beneficial to further ensuring the stable working performance of the touch assembly.

[0015] In some embodiments, the touch circuit board protrudes from the mounting frame at one end close to the bezel assembly; and the limiting surface is located outside the insertion slot.

[0016] The touch circuit board protrudes from the mounting frame at one end close to the bezel assembly, so as to be beneficial to avoiding the problem that infrared rays are difficult to cover the edge of the display area, thereby ensuring that the infrared rays can cover the entire display area of the interactive panel in all directions. On this basis, the limiting surface is located outside the insertion slot, and the abutting surface is located in the insertion slot, so that the positions of the limiting surface and the abutting surface can better match the setting mode that the touch circuit board protrudes from the mounting frame at one end close to the bezel assembly.

[0017] In some embodiments, the support body comprises a first connecting part and a second connecting part connected with the first connecting part, the first connecting part is used for connecting with the bezel assembly, and the second connecting part is used for connecting with the back plate of the interactive panel.

[0018] By connecting the first connecting part with the bezel assembly and connecting the second connecting part with the back plate of the interactive panel, the mounting and fixing of the bezel assembly and the back plate can be realized.

[0019] In some embodiments, the first connecting part has a first supporting surface used for abutting against the bezel assembly, and the second connecting part has a second supporting surface used for abutting against the back plate; wherein the plane where the first supporting surface is located and the plane where the second supporting surface is located have a preset included angle.

[0020] In the case that the first connecting part is connected with the bezel assembly, the first supporting surface on the first connecting part closely abuts against the bezel assembly, and in the case that the second connecting part is connected with the back plate, the second supporting surface on the second connecting part closely abuts against the back plate. On this basis, the plane where the first supporting surface is located and the plane where the second supporting surface is located have an included angle, that is, the plane where the first supporting surface is located and the plane where the second supporting surface are not parallel. This makes the bezel assembly have a slight tendency to tilt up on the front surface of the interactive panel after being mounted. Taking the case that the bezel assembly is a lower bezel assembly as an example, it can be found that the bezel assembly has a tendency similar to "upward tilting of chin" when observed from the front surface of the interactive panel. In this way, the bezel assembly and the bezel part of the adjacent side edge are not easy to form an obvious step difference.

[0021] In some embodiments, the preset included angle is greater than or equal to 1° and less than or equal to 2°.

[0022] The preset included angle is controlled between 1° and 2° in the embodiment, so that the step difference between the frame assembly and the frame part of the adjacent side can be obviously reduced, and the aesthetic appearance of the interactive panel is not affected due to the small preset included angle value.

[0023] In some embodiments, the support body further comprises a third connecting part connected with the first connecting part; the first connecting part and the third connecting part are both plate-shaped structures, the third connecting part is perpendicular to the first connecting part, the first connecting part is used for connecting with the side part of the frame assembly, and the third connecting part is used for connecting with the end part of the frame assembly.

[0024] The frame assembly is overall configured as a cuboid structure, and the first connecting part and the third connecting part are both plate-shaped structures, so that the first connecting part in plate-shaped structure can be better attached to the side surface of the frame assembly in the case of connecting the first connecting part with the side part of the frame assembly, thereby improving the stability of the connection. On this basis, the third connecting part is further connected with the end part of the frame assembly, so that the connection firmness and stability between the support body and the frame assembly can be further improved.

[0025] In some embodiments, the corner support further comprises a positioning column connected with the support body, and the positioning column is used for cooperating with a positioning hole on the frame assembly.

[0026] In the process of connecting the support body with the frame assembly, the positioning column can be first made to pass through the positioning hole on the frame assembly, and then the connection operation is implemented. In this way, the connection process of the support body and the frame assembly can be more convenient, and the positional displacement of the two in the connection process can be prevented.

[0027] In some embodiments, the corner support further comprises a glass blocking part connected with the support body, and the glass blocking part is used for limiting the glass cover plate of the interactive panel.

[0028] The corner support is provided with the glass blocking part connected with the support body, and in the process of installing the glass cover plate on the interactive panel, the glass blocking part can block the glass cover plate from the side of the interactive panel, so as to prevent the glass cover plate from sliding out from the side of the interactive panel in the installation process, thereby reducing the risk of falling of the glass cover plate.

[0029] In some embodiments, the corner support comprises a metal framework and a rubber coating at least partially covering the metal framework.

[0030] The corner support is provided with a metal framework, so that the corner support has good structural strength and structural rigidity, thereby ensuring good working stability of the corner support. In addition, the metal framework is covered with a rubber coating, which is conducive to protecting some wear-resistant components in contact with the corner support to avoid wearing related components such as glass cover plates due to the high hardness of the corner support. In addition, compared with a full metal piece, the structure of wrapping the metal framework with a rubber coating is also conducive to reducing the manufacturing cost.

[0031] The embodiment of the second aspect of the application provides an interactive panel, which comprises a back plate, a frame assembly and a touch assembly, the frame assembly and the touch assembly are located at adjacent sides of the interactive panel, and a corner support in any one of the above embodiments, the support body is connected with the frame assembly, the support body is also connected with the back plate, and the touch assembly is inserted into the insertion slot.

[0032] In the interactive panel in the embodiment of the application, the corner support comprises a support body and an insertion part, the support body is connected with the back plate, and the support body is also connected with the frame assembly, so that the frame assembly can be fixed to the back plate through the support body, thereby achieving the installation and fixation of the frame assembly. In addition, the corner support also has an insertion part connected with the support body, one end of the touch assembly is inserted into the insertion slot of the insertion part, so that the touch assembly is limited through the insertion slot. Therefore, the corner support has multiple functions, which can not only install and fix the frame assembly, but also limit the touch assembly on the adjacent side. In this way, it is not necessary to additionally provide a structure specially used for limiting the touch assembly. The application has multiple functions of the corner support, which is conducive to reducing the number of parts in the interactive panel, thereby optimizing the cost of the interactive panel.

[0033] In some embodiments, the frame assembly is connected with the back plate, an edge of the back plate is formed with a containing groove, and the touch assembly is arranged in the containing groove.

[0034] The containing groove is constructed on the edge of the back plate to accommodate the touch assembly, and the containing groove has a protective effect on the touch assembly, so that the containing groove can replace the independently manufactured frame. In this way, it is conducive to reducing the total processing time, thereby shortening the manufacturing period of the interactive panel. BRIEF DESCRIPTION OF DRAWINGS

[0060] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and embodiments.

[0062] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise explicitly specified and limited.

[0063] In the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0064] It is to be understood that when an element such as a layer, region or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element or intervening elements can be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present. It will be understood that, when a part is referred to as being "formed on" another part, it can be directly formed on the other part or there can be an intervening part. It will be understood that, when a part is referred to as being "connected to" another part, it can be directly connected to the other part or there can be an intervening part. As used herein, the term "vertical", "horizontal", "upper", "lower", "left", "right", and similar terms are intended for explanation purposes only and are not intended to be limiting.

[0065] In the related art, the frame and the back plate of some interactive flat panels are in a split structure, that is, the frame and the back plate are respectively processed and formed. In such an interactive flat panel, the corner support arranged at the corner position is mainly used to connect the frames of the two adjacent sides of the interactive flat panel.

[0066] Since it is difficult to independently process the frame, the processing time is relatively long, and part of the edge of the back plate of some interactive flat panels is bent to process a frame structure that is in an integrated structure with the back plate. In this way, the number of split frames can be reduced to improve the processing efficiency and reduce the cost of the interactive flat panel. For example, some interactive flat panels only retain an independent upper frame assembly or a lower frame assembly, and the frame structures of the left and right sides are integrally formed with the back plate.

[0067] For the interactive flat panel integrally formed with the back plate, the corner structure adopted in the related art cannot be applied, and the function thereof is relatively single, resulting in a large number of parts in the interactive flat panel. The corner support and the interactive flat panel aim to make the corner support applicable to the interactive flat panel integrally formed with the back plate and expand the function of the corner support.

[0068] Based on the above problems, the applicant proposes the technical scheme in the embodiments of the present application. Specifically, the corner support provided in the embodiments of the present application is applicable to the interactive flat panel integrally formed with the back plate, and the corner support in the embodiments of the present application has multiple functions. In addition to being able to fix the frame assembly, the corner support can also limit the touch assembly of the adjacent side. In this way, it is not necessary to additionally arrange a structure specially for limiting the touch assembly. By making the corner support have multiple functions, it is beneficial to reduce the number of parts in the interactive flat panel, thereby being beneficial to the cost optimization of the interactive flat panel.

[0069] The above is the core idea of the present application, and the technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0070] As shown in FIG. 1, the corner support 100 is arranged at the corner position of the interactive flat panel 200. The corner support 100 is mainly used to connect the frames of the two adjacent sides of the interactive flat panel 200. Figure 1 , Figure 2 , Figure 3 ,Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown in FIGS. 1-9, embodiments of the first aspect of the present application provide a corner support 10 for an interactive panel 1. The corner support 10 includes a support body 11 and a plug-in part 12. The support body 11 is provided with a connecting hole 115 for connecting with a back plate 40 of the interactive panel 1, and is further configured to connect with a bezel assembly 20. The plug-in part 12 is connected with the support body 11, and is formed with a plug-in slot 121 for limiting a touch assembly 30 of the interactive panel 1. The bezel assembly 20 and the touch assembly 30 are arranged on adjacent sides of the interactive panel 1.

[0071] Specifically, the back plate 40 is a housing plate located at the back side (non-light emitting side) of the interactive panel 1, and mainly functions to protect the internal structure of the interactive panel 1, such as a display panel, a diffusion plate, an optical film, etc.

[0072] The bezel assembly 20 is an assembly having a bezel structure independent of the back plate 40, that is, the bezel structure in the bezel assembly 20 is a split structure with the back plate 40, i.e., they are independently manufactured and formed. Exemplarily, the bezel assembly 20 can be a lower bezel assembly or an upper bezel assembly.

[0073] The side where the touch assembly 30 is located is not provided with a bezel structure independent of the back plate 40, that is, the back plate 40 can form a receiving groove 41 for accommodating the touch assembly 30 on the side where the touch assembly 30 is located, thereby replacing the bezel structure on this side.

[0074] Taking the bezel assembly 20 as a lower bezel assembly as an example, in this case, the touch assembly 30 is a touch assembly located on the left side or the right side of the interactive panel 1, and correspondingly, the corner support 10 is arranged at the lower left corner or the lower right corner of the interactive panel 1.

[0075] The corner support 10 in the embodiment of the present application, wherein the support body 11 is used to connect with the back plate 40 of the interactive panel 1, and the support body 11 is also used to connect with the frame assembly 20 of the interactive panel 1, so that the frame assembly 20 can be fixed to the back plate 40 of the interactive panel 1 through the support body 11, thereby realizing the installation and fixation of the frame assembly 20. In addition, the corner support 10 also has the plug-in part 12 connected with the support body 11, and one end of the touch assembly 30 of the interactive panel 1 can be plugged into the slot 121 of the plug-in part 12, so that the touch assembly 30 is limited through the slot 121. Therefore, the corner support 10 has multiple functions, which can not only install and fix the frame assembly 20, but also limit the touch assembly 30 of the adjacent side. In this way, it is not necessary to additionally set a structure specially used for limiting the touch assembly 30. The present application makes the corner support 10 have multiple functions, which is beneficial to reducing the number of parts in the interactive panel 1, thereby being beneficial to the cost optimization of the interactive panel 1.

[0076] As shown in Figure 7 , Figure 10 and Figure 11 , in some embodiments, the touch assembly 30 includes the mounting frame 31 and the touch circuit board 32, the mounting frame 31 is provided with the accommodation cavity 311, and the touch circuit board 32 is arranged in the accommodation cavity 311. The slot 121 is used for limiting the mounting frame 31, and the abutting surface 122 is formed in the slot 121 and used for abutting with the end surface 312 of one end of the mounting frame 31.

[0077] Exemplarily, the touch circuit board 32 can be an infrared circuit board having an infrared emission function. The infrared emitted by the infrared circuit board can be emitted through the opening on one side of the mounting frame 31, so that the infrared is distributed on the display side of the interactive panel 1. In this way, when a user touches the interactive panel 1, the control intention of the user can be recognized through the infrared, and the interactive panel 1 can give the user a corresponding response.

[0078] In the embodiment, the slot 121 is used for limiting the mounting frame 31, that is, the mounting frame 31 in the touch assembly 30 is plugged into the slot 121. On this basis, the abutting surface 122 is also arranged in the slot 121, and the abutting surface 122 abuts with the end of one end of the mounting frame 31 in the case that the mounting frame 31 is plugged into the slot 121. In this way, the abutting surface 122 can also limit the mounting frame 31 along the length direction of the mounting frame 31. Therefore, through the cooperation of the slot 121 and the abutting surface 122, the mounting frame 31 can be limited in different directions, so that the installation stability of the touch assembly 30 can be effectively improved, and the working performance stability of the touch assembly 30 can be ensured.

[0079] As shown in Figure 10As shown, in one of the embodiments, the abutting surface 122 is obliquely arranged relative to the length direction of the touch assembly 30, that is, the abutting surface 122 is an inclined surface.

[0080] In combination Figure 7 , Figure 11 Generally, the touch assembly 30 further comprises a light filtering strip 33 arranged at the opening position of the mounting frame 31, so that the infrared rays emitted by the touch circuit board 32 can pass through the light filtering strip 33. In some cases, the light filtering strip 33 and the mounting frame 31 are made by using a two-color injection molding process, so that the light filtering strip 33 and the mounting frame 31 are integrally formed, thereby having good connection strength between the light filtering strip 33 and the mounting frame 31. Generally, the interactive panel 1 also has a corresponding touch circuit board and light filtering strip on the side where the frame assembly 20 is located. For the sake of description, the light filtering strip on the side where the frame assembly 20 is located is referred to as a second light filtering strip. The light filtering strip 33 and the second light filtering strip are spliced by using an inclined surface at the corner position, so that a gap can be avoided between the light filtering strip 33 and the second light filtering strip.

[0081] Since the light filtering strip 33 and the mounting frame 31 are integrally formed, when the light filtering strip 33 is cut to form the inclined surface for splicing, the end of the mounting frame 31 is also cut to form an inclined surface.

[0082] In the embodiment, the abutting surface 122 is an inclined surface, which makes the abutting surface 122 can be matched with the inclined surface of the end of the mounting frame 31, so that the abutting surface 122 can have better stability when abutting with the end of the mounting frame 31.

[0083] As Figure 7 , Figure 10 shown, in some embodiments, the support body 11 is provided with a limiting protrusion 111, the limiting protrusion 111 has a limiting surface 1111, the limiting surface 1111 is arranged opposite to the insertion slot 121, and the limiting surface 1111 is used for abutting with the end of the touch circuit board 32 to limit the touch circuit board 32.

[0084] The limiting protrusion 111 is used for limiting the touch circuit board 32. Specifically, on the basis of the abutting surface 122 abutting with the end of the mounting frame 31 to limit the mounting frame 31 along the length direction of the mounting frame 31, the end of the touch circuit board 32 also abuts with the limiting surface 1111 of the limiting protrusion 111 to limit the touch circuit board 32 along the length direction of the mounting frame 31. In this way, the corner support 10 can limit the mounting frame 31 and the touch circuit board 32 of the touch assembly 30 at the same time, thereby being conducive to further ensuring the stable working performance of the touch assembly 30.

[0085] As Figure 4 , Figure 10As shown in one of the embodiments, the touch circuit board 32 extends out of the mounting frame 31 near one end of the frame assembly 20, and the limiting surface 1111 is located outside the slot 121.

[0086] Generally, a plurality of infrared LED lamp beads are arranged on the touch circuit board 32 to emit infrared rays. The infrared LED lamp bead closest to the end of the touch circuit board 32 often has a certain distance from the end surface of the touch circuit board 32. If the end of the touch circuit board 32 is flush with the end of the mounting frame 31, the infrared rays emitted by the infrared LED lamp bead closest to the end may have a certain distance from the edge of the display area of the interactive flat panel 1, making it difficult for the infrared rays to cover the entire display area.

[0087] In the embodiment, the touch circuit board 32 extends out of the mounting frame 31 near one end of the frame assembly 20, which is conducive to avoiding the problem that infrared rays are difficult to cover the edge of the display area, thereby ensuring that the infrared rays can cover the entire display area of the interactive flat panel 1 in all directions. On this basis, the limiting surface 1111 is located outside the slot 121, and the abutting surface 122 is located inside the slot 121, so that the positions of the limiting surface 1111 and the abutting surface 122 can better match the setting mode of the touch circuit board 32 extending out of the mounting frame 31 near one end of the frame assembly 20.

[0088] As shown in Figure 9 , Figure 10 and Figure 12 , in some embodiments, the support body 11 includes a first connecting portion 112 and a second connecting portion 113 connected with the first connecting portion 112, the first connecting portion 112 is used to connect with the frame assembly 20, and the second connecting portion 113 is used to connect with the back plate 40 of the interactive flat panel 1.

[0089] Exemplarily, the first connecting portion 112 and the frame assembly 20 can be connected through connecting members such as screws and bolts. Similarly, the second connecting portion 113 and the back plate 40 can be connected through connecting members such as screws and bolts.

[0090] By connecting the first connecting portion 112 with the frame assembly 20 and connecting the second connecting portion 113 with the back plate 40 of the interactive flat panel 1, the installation and fixation of the frame assembly 20 and the back plate 40 can be achieved.

[0091] As shown in Figure 12 , Figure 13As shown, in one of the embodiments, the first connecting part 112 has a first supporting surface 1121 for abutting against the frame assembly 20, and the second connecting part 113 has a second supporting surface 1131 for abutting against the back plate 40, wherein the plane in which the first supporting surface 1121 lies and the plane in which the second supporting surface 1131 lies have a preset included angle.

[0092] In the case where the first connecting part 112 is connected with the frame assembly 20, the first supporting surface 1121 on the first connecting part 112 is tightly attached to the frame assembly 20, and in the case where the second connecting part 113 is connected with the back plate 40, the second supporting surface 1131 on the second connecting part 113 is tightly attached to the back plate 40. On this basis, the plane in which the first supporting surface 1121 lies and the plane in which the second supporting surface 1131 lie have a preset included angle, that is, the plane in which the first supporting surface 1121 lies and the plane in which the second supporting surface 1131 lie are not parallel. This makes the frame assembly 20 have a slight tendency to tilt after installation on the front surface (the surface facing the light-emitting side) of the interactive panel 1. Taking the case where the frame assembly 20 is the lower frame assembly as an example, it can be found from the front surface of the interactive panel 1 that the frame assembly 20 has a tendency to tilt like a "chin". Such an arrangement is conducive to preventing the frame assembly 20 and the frame part (formed by bending the edge of the back plate 40) of the adjacent side from forming a significant step difference.

[0093] In one of the embodiments, the preset included angle between the plane in which the first supporting surface 1121 lies and the plane in which the second supporting surface 1131 lies is greater than or equal to 1° and less than or equal to 2°.

[0094] If the value of the above-mentioned preset included angle is too large, the front surface of the frame assembly 20 will be significantly tilted compared with other appearance surfaces of the front surface of the interactive panel 1, thereby affecting the aesthetic appearance of the interactive panel 1. Conversely, if the value of the above-mentioned preset included angle is too small, the step difference will be less obvious, and it will be difficult to reduce the step difference.

[0095] Based on the above reasons, the value of the above-mentioned preset included angle is controlled to be between 1° and 2° in the present embodiment. Such an arrangement can significantly reduce the step difference between the frame assembly 20 and the frame part of the adjacent side, and at the same time, the value of the preset included angle is small, and thus the aesthetic appearance of the interactive panel 1 will not be affected.

[0096] As shown in FIG. 1, the interactive panel 1 comprises a back plate 40, a frame assembly 20, a display panel 10, and a first connecting part 112 and a second connecting part 113. Figure 4 , Figure 9As shown, in some embodiments, the bracket body 11 further includes a third connecting portion 114 connected to the first connecting portion 112. Both the first connecting portion 112 and the third connecting portion 114 are plate-shaped structures. The third connecting portion 114 is perpendicular to the first connecting portion 112. The first connecting portion 112 is used to connect to the side of the frame assembly 20, and the third connecting portion 114 is used to connect to the end of the frame assembly 20.

[0097] The frame assembly 20 is generally constructed as a cuboid. Both the first connecting part 112 and the third connecting part 114 are plate-like structures. This allows the plate-like first connecting part 112 to fit snugly against the side of the frame assembly 20 when it is connected to the side of the frame assembly 20, thus improving the stability of the connection. Furthermore, the third connecting part 114 is also connected to the end of the frame assembly 20, further enhancing the strength and stability of the connection between the support body 11 and the frame assembly 20.

[0098] Furthermore, the end of the frame assembly 20 may be provided with a connecting ear plate, and the third connecting part 114 is connected to the connecting ear plate, thereby realizing the connection between the third connecting part 114 and the frame assembly 20.

[0099] like Figure 8 , Figure 9 As shown, in some embodiments, the corner bracket 10 further includes a positioning post 13, which is connected to the bracket body 11 and is used to engage with the positioning hole on the frame assembly 20.

[0100] During the connection of the bracket body 11 and the frame assembly 20, the positioning post 13 can be passed through the positioning hole on the frame assembly 20 first, and then the connection operation can be carried out. This makes the connection process between the bracket body 11 and the frame assembly 20 more convenient and prevents the two from shifting during the connection process.

[0101] like Figure 8 , Figure 10 As shown, in some embodiments, the corner bracket 10 further includes a glass blocking part 14 connected to the bracket body 11, which is used to limit the glass cover plate 50 of the interactive flat panel 1.

[0102] The corner bracket 10 is provided with a glass blocking part 14 connected to the bracket body 11. During the installation of the glass cover plate 50 on the interactive flat panel 1, the glass blocking part 14 can block the glass cover plate 50 from the side of the interactive flat panel 1, thereby preventing the glass cover plate 50 from sliding out from the side of the interactive flat panel 1 during the installation process, so as to reduce the risk of the glass cover plate 50 falling.

[0103] like Figure 10 , Figure 13As shown, in some embodiments, the corner support 10 comprises a metal framework 101 and a rubber coating 102 covering the metal framework 101.

[0104] Exemplarily, the metal framework 101 can be an iron framework, an aluminum framework, an alloy framework, etc.

[0105] The corner support 10 is provided with the metal framework 101, so that the corner support 10 can have good structural strength and structural rigidity, thereby ensuring that the corner support 10 has good working stability. In addition, the metal framework 101 is covered with the rubber coating 102, which is conducive to protecting some wear-resistant components in contact with the corner support 10, so as to avoid wearing related components, such as the glass cover plate 50, due to the excessively high hardness of the corner support 10. In addition, compared with a full metal piece, the structure of wrapping the metal framework 101 with the rubber coating 102 is also conducive to reducing the manufacturing cost.

[0106] Reference Figures 1 to 7 The embodiments of the second aspect of the present application provide an interactive panel 1, which comprises a back plate 40, a frame assembly 20, a touch assembly 30, and the corner support 10 in any of the above embodiments. The frame assembly 20 and the touch assembly 30 are located at adjacent side edges of the interactive panel 1, the support body 11 of the corner support 10 is connected with the frame assembly 20, the support body 11 is also connected with the back plate 40, and the touch assembly 30 of the corner support 10 is inserted into the insertion slot 121.

[0107] In the interactive panel 1 in the embodiments of the present application, the corner support 10 comprises the support body 11 and the insertion part 12, the support body 11 is connected with the back plate 40, and the support body 11 is also connected with the frame assembly 20. Thus, the frame assembly 20 can be fixed to the back plate 40 through the support body 11, so as to realize the installation and fixation of the frame assembly 20. In addition, the corner support 10 also has the insertion part 12 connected with the support body 11, one end of the touch assembly 30 is inserted into the insertion slot 121 of the insertion part 12, so that the touch assembly 30 is limited through the insertion slot 121. Thus, the corner support 10 has multiple functions, which can not only install and fix the frame assembly 20, but also limit the touch assembly 30 at the adjacent side edges. In this way, it is not necessary to additionally provide a structure specially for limiting the touch assembly 30. The present application makes the corner support 10 have multiple functions, which is conducive to reducing the number of parts in the interactive panel 1, thereby being conducive to the cost optimization of the interactive panel 1.

[0108] As shown in Figure 2 , Figure 7 In some embodiments, the frame assembly 20 is connected with the back plate 40, the edge of the back plate 40 forms a receiving groove 41, and the touch assembly 30 is arranged in the receiving groove 41.

[0109] The accommodating groove 41 can be made by bending sheet metal.

[0110] An accommodating groove 41 for accommodating the touch assembly 30 is configured at the edge of the back plate 40, and the accommodating groove 41 has a protective effect on the touch assembly 30, so that the accommodating groove 41 can replace the frame made independently. In this way, the total processing time is reduced, thereby shortening the manufacturing cycle of the interactive panel 1.

[0111] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
