The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0058] In the current interactive flat panel technology field, the frame assembly consists of a frame, inner corners, outer corners, glass blocks and glass. The glass is placed straight up and down on the filter strips of the frame, and is limited by the side of the four frame filter strips, and then fixed by the glass block. The glass block is fixed to the frame by screws, and the back panel is fixed to the frame by screws; the frame is an aluminum alloy structure, connected by die-cast inner corners and plastic outer corners. The structural design and assembly of the entire frame assembly are relatively complex, and there are many types and quantities of materials. This leads to high material and assembly costs.

[0059] Based on this, the present invention provides a frame structure, by setting a first accommodating cavity in the first frame and setting a first filter in the first accommodating cavity; by setting a snap-in groove on the first filter, the glass is snap-connected in the snap-in groove to ensure the reliability of the connection between the first filter and the first frame, and the reliability of the connection between the glass and the frame structure, thereby reducing the number of glass blocks used to clamp the glass and the frame structure to reduce material costs; at the same time, it can also make the installation of the frame assembly simpler, thereby reducing assembly costs.

[0060] See also Figures 3 to 15 As shown, an embodiment of the present invention provides a frame structure 100, which includes a frame assembly 110 and a plurality of first filters 120. The frame assembly 110 includes a plurality of first frames 111, each of which is connected end to end to enclose and define an installation area 180 for installing a display module 400. Each first frame 111 is constructed with a first accommodating cavity 1115 that passes through along the extension direction of the first frame 111, and an opening that is connected to the first accommodating cavity 1115, and the opening is arranged on a side of the frame facing the installation area; the first filters 120 correspond one-to-one to the first frames 111, each of which is arranged in the first accommodating cavity 1115, and a portion of each of which extends from the opening 1116; wherein each of the first filters 120 is constructed with a snap-in groove 123 that extends along the extension direction of the frame, and the snap-in groove 123 is used to snap-in with the glass 410.

[0061] The frame structure 100 provided by the present invention defines an installation area 180 for installing the display module 400 by connecting a plurality of first frames 111 end to end, and provides a first accommodating cavity 1115 in the first frame 111 to accommodate the first filter 120. The first filter 120 is provided in the first accommodating cavity 1115, and the first filter 120 is limited by the cavity wall of the accommodating cavity 122, so that the reliability of the connection between the first filter 120 and the first frame 111 can be improved. The clamping groove 123 is provided on the first filter 120, and the glass 410 is clamped in the clamping groove 123 on the first filter 120 to achieve the connection between the glass 410 and the frame assembly 110. Such a configuration can not only improve the reliability of the connection between the glass 410 and the frame structure 100, but also reduce the number of glass pressing blocks used to press the glass 410, thereby reducing the material cost, and at the same time, it can make the assembly of the entire frame structure 100 simpler, thereby reducing the assembly cost. The above structure can not only improve the reliability of the connection between the first filter 120 and the first frame 111, but also improve the reliability of the connection between the glass and the frame structure 100 and reduce the material cost and assembly cost.

[0062] It should be noted that, in the embodiment of the present invention, the first frame 111 is made of sheet metal and formed by a cold stamping process. Figure 4 As shown, the first frame 111 on the left is called the left frame, the first frame 111 on the top is called the top frame, and the first frame 111 on the right is called the right frame. The left frame, the top frame, and the right frame are fixedly connected by screws or welding to form a U-shaped frame. The extension direction of the first frame 111 is the length direction of the first frame 111. For example, Figure 4 In the figure, the extension direction of the left and right frames is the up-down direction in the figure, and the extension direction of the upper frame is the left-right direction in the figure. Compared with the prior art, the structural form of the aluminum alloy frame can save the inner and outer corners used to connect the two aluminum alloy frames, thereby reducing the types and quantities of materials, making the frame assembly 110 easier to assemble, thereby reducing the material and installation costs. The first filter 120 is made of plastic and is formed by an extrusion process.

[0063] In some embodiments, such as Figure 5As shown, each first frame 111 includes a side plate 1111, and a first limiting plate 1112 and a second limiting plate 1113 connected to the opposite sides of the side plate 1111, and the side plate 1111, the first limiting plate 1112 and the second limiting plate 1113 jointly enclose a first accommodating cavity 1115; wherein, a side edge of the first filter element 120 facing the first limiting plate 1112 is constructed as a limiting flange 121 bent in a direction close to the first limiting plate 1112, and the limiting flange 121 is bent to abut against the side of the first limiting plate 1112 away from the first filter element 120, so as to limit the first filter element 120 from moving along an extension direction perpendicular to the first frame 111. By providing a limiting flange 121 on the first filter 120, and by abutting the limiting flange 121 against the side of the first limiting plate 1112 facing away from the first filter 120 to limit the first filter 120, the first filter 120 can be prevented from being separated from the first frame 111, so as to ensure the reliability of the cooperation between the first filter 120 and the first frame 111.

[0064] It should be noted that the interactive tablet 10 includes a frame structure 100, a display module 400 and a back plate 200, wherein the display module 400 is installed in the installation area 180 formed by the frame assembly 110 and is fixedly connected to the frame assembly 110. The surface of the display module 400 used for presenting images is the display surface, and the surface away from the display surface is the back surface. The back plate 200 is arranged on the back of the display module 400 and is fixedly connected to the frame structure 100. In an embodiment of the present invention, the first limiting plate 1112 is closer to the back plate 200 than the second limiting plate 1113. The limiting flange 121 of the first filter 120 is clamped and limited with the first limiting plate 1112, so that when the back plate 200 is fixedly connected with the frame structure 100, the back plate 200 can block the position where the first filter 120 is clamped with the first limiting plate 1112, thereby making the interactive tablet 10 more beautiful.

[0065] like Figure 5As shown, in some embodiments, the frame structure 100 further includes a plurality of first touch frames 130, the number of the first touch frames 130 corresponds to the number of the first optical filters 120, each first optical filter 120 is configured with a receiving cavity 122 extending along its extension direction, and each first touch frame 130 is fixed in the receiving cavity 122. It can be understood that the first touch frame 130 generally includes a printed circuit board and an infrared tube, the first touch frame 130 is arranged along the extension direction of the receiving cavity 122, and the infrared tube is electrically connected to the printed circuit board and faces the light emitting portion of the first optical filter 120. The accommodating cavity 122 on each first optical filter 120 is open at both ends along the extension direction, and the first touch frame 130 enters the accommodating cavity 122 from the opening at one end corresponding to the first optical filter 120. When the first touch frame 130 needs to be inspected or replaced, it can be taken out from the opening of the accommodating cavity 122, so that the installation and disassembly of the first touch frame 130 in the accommodating cavity 122 becomes convenient and quick, and there is no need to go through a complicated disassembly process to disassemble the frame structure 100, thereby saving the time required for inspection, maintenance and replacement of components and saving labor costs.

[0066] Specifically, in one embodiment of the present invention, Figure 7 As shown, grooves are formed on two oppositely disposed walls of the accommodating cavity 122 of the first optical filter 120, and the notches of the grooves on the two walls are disposed oppositely, and two opposite side surfaces of the first touch frame 130 are respectively engaged in the two oppositely disposed grooves to achieve mutual fixation of the first touch frame 130 and the first optical filter 120. With such a configuration, the structure is simple, and the fixed connection between the first touch frame 130 and the first optical filter 120 can be achieved without redundant components, thereby making the disassembly and assembly of the first touch frame 130 and the first optical filter 120 simpler and more convenient.

[0067] like Figures 8 to 10 As shown, in some embodiments, the frame structure 100 further includes a limiting bracket 140, and a limiting bracket 140 is disposed between two adjacent first frames 111, and two adjacent side surfaces of the limiting bracket 140 are respectively against two adjacent first touch frames 130. By disposing the limiting bracket 140 between two adjacent first frames 111, the first touch frames 130 in the two adjacent first frames 111 are limited to prevent the first touch frames 130 from moving relative to the first frames 111, thereby ensuring the stability of the first touch frames 130 in the frame structure 100.

[0068] It should be noted that, in the embodiment of the present invention, the position limiting bracket 140 includes a decorative surface 143, which is a surface on the position limiting bracket 140 located on the same side as the back plate 200, and the decorative surface is flush with the surface of the upper frame located on the same side as the back plate 200. With such a configuration, there is no need to set up another structure for decoration, thereby reducing the types of materials and further reducing costs. The outer corner surface on the position limiting bracket is constructed as an arc surface, and accordingly, the outer corner surfaces of the left and right frames are also configured as arc surfaces. With such a configuration, the arc surfaces of the outer corners on the left and right frames can fit with the outer corner surfaces of the position limiting bracket 140 to limit each other.

[0069] like Figure 8 and Fig.10 As shown, in some embodiments, the limiting bracket 140 includes a first limiting surface 141 and a buckle 142. The first limiting surface 141 is used to abut against a first frame 111; the buckle 142 includes a clamping surface 1421, and the clamping surface 1421 is spaced from the first limiting surface 141 in the thickness direction of the side wall of the first frame, and the side wall of the first frame 111 is clamped between the first limiting surface 141 and the clamping surface 1421. The limiting bracket 140 and the first frame 111 are pre-fixed by the first limiting surface 141 abutting against the first frame 111 and the buckle 142 engaging with the first frame 111, so that the assembly between the limiting bracket 140 and the first frame 111 is simpler, and no bolts or other materials are required between the two, thereby saving material costs.

[0070] Specifically, the surface of the limiting bracket 140 opposite to the decorative surface 143 abuts against the surface of the left frame facing the back plate 200; of course, the surface of the limiting bracket 140 on the right side opposite to the decorative surface abuts against the surface of the right frame facing the back plate 200. It should be noted that the side surfaces of the left and right frames on the side of the back plate 200 are lower than the side surfaces of the upper frame on the side of the back plate 200, and the height difference between the side surfaces of the left and right frames on the side of the back plate 200 and the side surfaces of the upper frame on the side of the back plate 200 is just equal to the thickness between the decorative surface of the limiting bracket 140 and the surface opposite to the decorative surface.

[0071] In one embodiment of the present invention, two spaced-apart notches are provided on the side surfaces of the left and right frames on one side of the back panel 200, one notch is used to avoid the buckle 142 to provide an operating space for the buckle 142 to be connected with the frame; the other notch is used to engage with the protruding part on the limiting bracket 140, so that the limiting part of the notch and the protruding part on the limiting bracket 140 can limit each other in the extension direction of the left and right frames, thereby improving the reliability of the connection between the limiting bracket 140 and the left and right frames.

[0072] The side surface of the limiting bracket facing the upper frame abuts against the end surface of the first touch frame 130 provided in the upper frame to limit the movement of the first touch frame 130 in the upper frame along the extension direction of the upper frame. The side surface of the limiting bracket 140 facing the left frame or the right frame is set as a plane, and the side surface abuts against the first touch frame 130 located in the left frame or the right frame to limit the movement of the first touch frame 130 in the left frame or the right frame.

[0073] It should be noted that, after the limiting bracket 140 cooperates with the upper frame and the left frame or the right frame, by fixing the back plate 200 with the frame structure 100, the side portion of the limiting bracket 140 facing the back plate 200 can abut against and fit with the back plate 200, so that the limiting bracket 140 can be limited by the back plate 200, thereby achieving the final limit of the limiting bracket 140. In other words, the limiting of the limiting bracket 140 is achieved by the joint action of the upper frame, the left frame or the right frame, and the back plate 200.

[0074] like Figure 3 and Figure 4 As shown, in some embodiments, the frame assembly 110 includes three first frames 111, and the three first frames 111 are enclosed to define an installation area with a gap; the frame structure 100 also includes a second frame 150, the second frame 150 is arranged at the gap, and the two ends of the second frame 150 are connected to the two first frames 111 arranged oppositely. It should be noted that the three first frames 111 are respectively the left frame, the upper frame and the right frame described above. After the left frame, the upper frame and the right frame are connected, a U-shaped frame is formed, so that the ends of the snap-in groove 123 on the first filter 120 located in the left and right frames are open, so that when installing the glass, the glass can be snapped into the snap-in groove 123 through the opening, and the glass can be pushed into the snap-in groove 123 in the first filter 120 in the upper frame in the direction of the upper frame. In this way, the glass can be engaged with the snap-in groove 123 in the first filter element 120 in the left frame, the upper frame and the right frame. This is not only simple and convenient to install, but also does not require special materials for fixing, thereby reducing the types of materials and reducing production costs. In this embodiment, the second frame 150 is made of aluminum alloy and is formed by hot extrusion combined with CNC processing. The second filter element 151 in the second frame 150 is installed in advance.

[0075] like Fig.11As shown, in one embodiment, the second frame 150 includes a first support plate 152 and a second support plate 153 which are arranged opposite to each other and spaced from each other, the extension direction of the first support plate 152 and the second support plate 153 is consistent with the extension direction of the second frame 150, and a receiving groove 154 is defined between the first support plate 152 and the second support plate 153; the frame structure also includes a second filter 151, the second filter 151 is clamped in the receiving groove 154, and the edges of the glass 410 corresponding to the second filter 151 are against the second filter 151. In this way, the movement of the second filter 151 is limited by the receiving groove to improve the reliability of the connection between the second filter 151 and the second frame. Specifically, the first support plate 152 is provided with a guide rib protruding toward the second support plate 153, and the extension direction of the guide rib is consistent with the extension direction of the first support plate 152; the end of the second support plate is folded in the direction close to the first support plate 152 to construct a bent edge 1531. The second filter 151 is provided with guide grooves on two sides opposite to the first support plate 152 and the second support plate 153, and the guide ribs and the bent edges are respectively clamped in the corresponding guide grooves. In this embodiment, a middle frame 156 is further provided in the second frame 150, and the middle frame 156 is supported between the two groove walls of the accommodating groove 154 to improve the strength of the second frame 150.

[0076] like Figure 12 to Figure 14 As shown, in one embodiment, the frame structure 100 further includes a corner piece 160, and a corner piece 160 is provided at both ends of the second frame 150, and two adjacent side surfaces of each corner piece 160 are respectively against the first filter 120 of the first frame 111 and the end of the second filter 151 in the second frame 150. By providing the corner pieces 160 at both ends of the second frame 150, the connection between the two ends of the second frame 150 and the first frame 111 is achieved, and the corner pieces 160 are also used to limit the filters in the first frame 111 and the second frame 150, so that the positions between the first filter 120, the second filter 151 and the frame are more reliable, and at the same time, the problem of excessive gaps between the first filters 120 and the second filters 120, 151 can be effectively avoided.

[0077] Specifically, in this embodiment, the corner piece 160 is a plastic piece, compared to the related art that uses a zinc alloy die-casting inner corner piece 160 combined with a plastic outer corner piece 160 to achieve the connection between the first frame 111 and the second frame 150. In this solution, only one corner piece 160 is needed to achieve the connection between the first frame 111 and the second frame 150, and at the same time, the filter can be limited.

[0078] like Fig.12As shown, in one embodiment, a second limiting groove 161 is configured on one side of the corner piece 160, and the first touch frame 130 in the first optical filter 120 disposed in the first frame 111 is snapped into the second limiting groove 161. By providing the second limiting groove 161 on the corner piece 160, and snapping the first touch frame 130 in the first optical filter 120 in the first frame 111 into the second limiting groove 161, the first touch frame 130 is limited.

[0079] Among them, one side of the corner piece 160 is in contact with the side of the left frame or the right frame on the same side as the back plate 200, and a plurality of stud holes are provided on the corner piece 160. The corner piece 160 is fixed to the left frame or the right frame by bolts; the corner piece 160 is also fixed to the second frame 150 by bolts; and the back plate 200 is also fixed to the corner piece 160 by bolts. In this way, the left frame, the second frame 150 and the back plate 200 can be fixedly connected to each other through one corner piece 160, with fewer types of materials and convenient connection.

[0080] like Fig.14 As shown, in one embodiment, one end of the first frame 111 facing the second frame 150 is constructed as an arc structure, and the position where the arc structure is connected to the corner piece 160 is constructed with a folding edge 1114 bent toward the installation area 180; the corner piece 160 is constructed with an avoidance groove 162, and the folding edge 1114 is accommodated in the avoidance groove 162; the side of the second frame 150 is in contact with the side of the folding edge 1114. The avoidance groove 162 on the corner piece 160 provides a space for accommodating the folding edge 1114 on the first frame 111; and the side of the second frame 150 is in contact with the side of the folding edge 1114. On the one hand, the folding edge 1114 can be mutually limited with the second frame 150 to ensure the gap between the first frame 111 and the second frame 150; on the other hand, the side of the folding edge 1114 can be used as a positioning reference for the second frame 150, so that the installation is easier and the installation efficiency is improved.

[0081] like Fig.15As shown, in one embodiment, the frame structure 100 also includes a glass block 170, one end of the glass block 170 is fixedly connected to the second frame 150, and the other end of the glass block 170 is used to press against the glass; wherein, the glass block 170 is made of plastic. In this embodiment, the glass is fixed by the glass block 170, thereby ensuring the reliability of the connection between the glass and the frame structure 100. The glass block 170 is made of plastic material, which can prevent the glass from being scratched during assembly. At the same time, there is no need to attach foam to protect the glass. Compared with the glass block made of metal material, it can save materials and facilitate installation, thereby reducing material and assembly costs. Specifically, the glass block 170 is fixed to the second frame 150 by bolts. It should be noted that the hardness of the plastic material in the glass block 170 should be lower than the hardness of the ink on the glass surface, so that the glass block 170 will not scratch the ink on the glass surface.

[0082] like Fig.11 As shown, in one embodiment, the second frame 150 is configured with a second accommodating cavity 157 that passes through along its extension direction, and the frame structure 100 further includes a second touch frame 155, which is fixed in the second accommodating cavity 157. The structure and function of the second touch frame 155 are the same as those of the first touch frame described above, and will not be described in detail here.

[0083] like Figure 1 and Figure 2 As shown, an embodiment of the present invention further provides an interactive flat panel 10, and the interactive flat panel 10 includes the frame structure 100 as described above. Using the frame structure 100 as described above in the interactive flat panel 10 can not only improve the reliability of the connection between the glass and the frame structure 100, but also reduce the number of glass pressing blocks used to press the glass, thereby reducing the material cost, and at the same time make the assembly of the entire frame structure 100 simpler, thereby reducing the assembly cost. Through the above structure, not only can the reliability of the connection between the first filter 120 and the first frame 111 be improved, but also the reliability of the connection between the glass and the frame structure 100 can be improved, and the material cost and assembly cost can be reduced.

[0084] like Figure 1 and Figure 2 As shown, in one embodiment, the interactive tablet 10 further includes a display module 400, a back panel 200 and a plastic frame 300. The display module 400 is installed in the installation area and fixedly connected to the frame structure 100; the back panel 200 is covered on the back of the display module 400 and fixedly connected to the frame assembly 110; the plastic frame 300 is pressed between the back panel 200 and the first filter 120. By arranging the plastic frame 300 between the back panel 200 and the first filter 120, the glass is fixed to prevent the glass from being separated from the frame structure 100, thereby ensuring the reliability of the entire interactive tablet 10.

[0085] An embodiment of the present invention further provides an assembly method of an interactive flat panel, which is used to assemble the above interactive flat panel. The assembly method of the interactive flat panel 10 includes the following steps: step S10, assembling the frame assembly 110, and installing multiple first filters 120 into the accommodating cavity 122 of the first frame 111 respectively; step S20, clamping the glass into the clamping groove 123 from the ends of two oppositely arranged first filters 120, and pushing the glass in the direction of another first frame 111 connected to the two oppositely arranged first frames 111, so that three adjacent edges on the glass are respectively clamped into the clamping grooves 123 on the three adjacent first filters 120.

[0086] The glass assembly is inserted into the clamping groove 123 of the first filter 120 in the U-shaped frame formed by the left frame, the upper frame and the right frame in a side-entry manner. No glass pressing block is needed to fix the glass at the positions of the left frame, the upper frame and the right frame. This can reduce the number of materials and simplify the assembly work, thereby reducing the material and assembly costs.

[0087] In the assembly method of the interactive tablet 10 provided in this embodiment, in step S10, assembling the frame assembly 110, installing the plurality of first optical filters 120 into the accommodating cavity 122 of the first frame 111 respectively also includes: connecting the left limit bracket 140 with the left frame and the upper frame; connecting the right limit bracket 140 with the right frame and the upper frame. Install the first touch frames 130 into the corresponding first optical filters 120 respectively. Install the first touch frame 130 in the second frame 150 into the second frame 150, and then connect the four first touch frames 130. Install the first optical filters 120 into the corresponding frames respectively.

[0088] After the glass is inserted into the clamping groove 123 from the ends of the two first filters 120 arranged opposite to each other in step S20, the following steps are further performed: connecting the left corner piece 160 to the left frame and the second frame 150, and connecting the right corner piece 160 to the right frame and the second frame 150. Then, the glass pressing block is connected to the second frame 150 to press the glass. Finally, the back panel 200 is connected to the first frame 111, the second frame 150, the limiting bracket 140 and the corner piece 160 by screws. In this way, the assembly of the entire interactive flat panel 10 is realized.
