The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0040] In interactive flat panels, the bezel structure typically includes a top bezel, a bottom bezel, a left bezel, and a right bezel. These four bezels are connected and interlocked by a connecting structure to surround and protect the glass cover. The bottom bezel specifically surrounds and protects the bottom edge of the glass cover.

[0041] Currently, the bottom bezel structure typically includes a frame, a touch component, multiple glass supports, multiple welding supports, multiple small back cover supports, and a small back cover. The frame is formed using a roll forming process. The multiple glass supports and welding supports are all attached to the frame with screws. The touch component is pressed into the frame by the welding supports. The multiple glass supports and the touch component together clamp and support the glass cover. The multiple small back cover supports are attached one-to-one with the welding supports using screws. The small back covers are also attached to the multiple small back cover supports with screws. When the frame is used to house integrated control buttons and integrated circuit boards, the small back covers are used to shield the integrated control buttons and integrated circuit boards housed within the frame. However, in the above structure, the frame's cross-section is usually rectangular or trapezoidal, resulting in high material costs. Furthermore, the frame's processing involves blanking, cutting, flanging, threading, forming, and tapping, leading to low processing efficiency.

[0042] In view of this, the present invention provides an embodiment of a lower frame structure 100. Compared with the traditional frame 1 with a rectangular or trapezoidal cross-section, in the frame 1 of the embodiment of the present invention, the first piece 11 and the second piece 12 are arranged in an L-shape, and the second piece 12 and the third piece 13 are arranged in an L-shape. This can reduce structural features, reduce material costs, require only blanking and cutting processes, and omit processes such as flanging, toothing, forming and tapping, thereby improving processing efficiency.

[0043] For the lower border structure 100 mentioned above, please refer to Figures 1 to 4 The lower frame structure 100 includes a frame 1, a first support 2, a touch component 3, and a second support 4. The frame 1 includes a first piece 11, a second piece 12, and a third piece 13 connected in sequence. The first piece 11 and the third piece 13 are arranged opposite each other. The first piece 11 and the second piece 12 are arranged in an L-shape, and the second piece 12 and the third piece 13 are also arranged in an L-shape. The first support 2 includes a first plate 21, a second plate 22, and a first protrusion 23. The first plate 21 and the second plate 22 are connected and are arranged at an angle. The first plate 21 is fixed to the first piece 11, and the end of the second plate 22 away from the first plate 21 abuts against the third piece 13 facing the first plate. On the surface of plate 21, a first protrusion 23 is connected to the surface of the second plate 22 facing away from the second sheet 12. The first protrusion 23 is disposed opposite to the third sheet 13. The third sheet 13, the second plate 22, and the first protrusion 23 enclose a slot 24. The touch component 3 is inserted into the slot 24 and has a step 31. The second bracket 4 is connected to the first plate 21. The second bracket 4 at least partially abuts against the horizontal wall of the step 31 of the touch component 3. The second bracket 4 and the vertical wall of the step 31 of the touch component 3 are spaced apart and form a first clamping space. The first clamping space is used to accommodate the glass cover plate 200. The second bracket 4 and the vertical wall of the step 31 of the touch component 3 jointly clamp the glass cover plate 200. The first sheet 11 and the third sheet 13 extend vertically in the same direction on opposite sides of the second sheet 12, and the vertical extension height of the first sheet 11 is less than the vertical extension height of the third sheet 13. In addition, the first plate 21 is perpendicularly connected to the second plate 22, and the first protrusion 23 is perpendicularly connected to the surface of the second plate 22 opposite to the first plate 21.

[0044] In some embodiments, there are multiple first brackets 2 and multiple second brackets 4, with multiple first brackets 2 arranged at intervals. The first plate 21 of a first bracket 2 is connected to the first piece 11 of the frame 1, and a second bracket 4 is connected to the first plate 21 of a first bracket 2.

[0045] In some embodiments, please refer to Figure 4The surface of the third piece 13 facing the first piece 11 has an arc-shaped protrusion 131. The second plate 22 is located above the arc-shaped protrusion 131 and abuts against the arc-shaped protrusion 131. In this way, the arc-shaped protrusion 131 supports the second plate 22, and the second plate 22 abuts against the surface of the third piece 13 facing the first piece 11, which can improve the stability and structural strength of the second plate 22, reduce the deformation of the second plate 22 under pressure, and thus improve the structural strength of the first support 2.

[0046] In some embodiments, please refer to Figure 4 The second plate 22 and the third piece 13 are welded to the surface of the first piece 11. This method improves the stability and structural strength of the second plate 22, reduces deformation under pressure, and thus enhances the structural strength of the first support 2.

[0047] In some embodiments, please refer to Figure 5 and Figure 6 The second bracket 4 is provided with a first plug-in structure 41, which is located above the touch component 3 and is used to plug into the back plate 300. This improves the stability of the back plate 300. It is understood that the first plug-in structure 41 includes, but is not limited to, a post or a socket.

[0048] Please see Figure 4 The first plate 21 is provided with a plurality of first hollow holes 211, which are spaced apart; and / or, the second plate 22 is provided with a plurality of second hollow holes 221, which are spaced apart. Through the above method, the weight of the first support 2 can be reduced, and material costs can be lowered. It should be noted that the first hollow holes 211 and the second hollow holes 221 are hollow holes of different sizes and shapes, or the first hollow holes 211 and the second hollow holes 221 are hollow holes of the same size and shape, or the first hollow holes 211 and the second hollow holes 221 are integrally formed hollow areas, etc.

[0049] Please see Figure 5 The lower frame structure 100 includes a rivet 51, which comprises a first end, a connecting portion, and a second end connected in sequence. The first end abuts against the surface of the first piece 11 facing away from the first plate 21, the connecting portion passes through the first piece 11 and the first plate 21 in sequence, and the second end abuts against the surface of the first plate 21 facing away from the first piece 11. Compared with the traditional screw connection method, the rivet connection method can improve the assembly efficiency of the first piece 11 and the first plate 21, thereby improving the assembly efficiency of the frame 1 and the first bracket 2.

[0050] Please see Figures 5 to 7The first support 2 includes a second protrusion 25, which is connected to the surface of the second plate 22 facing away from the second sheet 12. The lower frame structure 100 includes a connector 6 and a third support 7. One end of the connector 6 is fixed to the second protrusion 25, and the other end of the connector 6 is used to fix it to the third support 7 and the back plate 300. The back plate 300 is located between the connector 6 and the third support 7, and the third support 7 is used to abut against the glass cover 200. In this way, an interlocking structure can be formed between the first support 2, the connector 6, the third support 7, and the back plate 300, which helps to improve the stability of the glass cover 200, the back plate 300, and the frame 1. It should be noted that both the second support 4 and the third support 7 are used to abut against the glass cover 200. The second support 4 is used to achieve the pre-fixation or pre-positioning of the glass cover 200, and the third support 7 is used to achieve the final fixation or final positioning of the glass cover 200.

[0051] In some embodiments, there are multiple second protrusions 25, connectors 6 and third brackets 7, with multiple second protrusions 25 spaced apart, and the two ends of a connector 6 are respectively connected to a second protrusion 25 and a third bracket 7.

[0052] Please see Figure 7 The lower frame structure 100 includes a first screw connector 52 and a second screw connector 53. The first screw connector 52 passes through one end of the connector 6 and is screwed onto the second protrusion 25 so that one end of the connector 6 is fixed to the first bracket 2. The second screw connector 53 passes through the other end of the connector 6 and the back plate 300 in sequence and is screwed onto the third bracket 7 so that the other end of the connector 6 is fixed to the back plate 300 and the third bracket 7. The back plate 300 is located between the connector 6 and the third bracket 7. The surface of the third bracket 7 facing away from the back plate 300 is used to abut against the glass cover plate 200.

[0053] In some embodiments, please refer to Figures 5 to 7 The third bracket 7 is provided with a second plug-in structure 71, which is located above the touch component 3 and is spaced apart from the second screw connector 53. The second plug-in structure 71 is used to plug into the back plate 300. This improves the stability of the back plate 300. It is understood that the second plug-in structure 71 includes, but is not limited to, a post or a socket.

[0054] Please see Figures 5 to 7The vertical walls of the steps 31 of the third support 7 and the touch component 3 are spaced apart, forming a second clamping space. The second clamping space is used to accommodate the glass cover 200. The vertical walls of the steps 31 of the third support 7 and the touch component 3 jointly clamp the glass cover 200. In this way, the second clamping space and the first clamping space cooperate to clamp one part of the glass cover 200 along the length direction of the glass cover 200, and the vertical walls of the steps 31 of the first support 2 and the touch component 3 jointly clamp the other part of the glass cover 200, effectively improving the stability of the glass cover 200.

The lower frame structure 100 includes a shielding member 8 and a third screw connector 54, which passes through the shielding member 8 and is screwed to the third plate 26. In this way, the shielding member 8 can shield the frame 1, the first support 2, the second support 4, the third support 7, and the connector 6, thus providing protection and reducing the risk of loosening of any one or more of the frame 1, the first support 2, the second support 4, the third support 7, and the connector 6 due to collisions.

[0056] In some embodiments, please refer to Figure 8 The shielding member 8 includes a first shielding wall 81 and a second shielding wall 82 that are vertically connected. The first shielding wall 81 is connected to the third plate 26 and is parallel to the third plate 26. The second shielding wall 81 is spaced apart from the first plate 21.

[0057] Please see Figure 8 The frame 1 includes a fourth piece 14, which is connected to the end of the third piece 13 away from the second piece 12. The fourth piece 14 is inclined relative to the third piece 13 and is located above the touch component 3. The fourth piece 14 is at least partially inclined and abuts against the touch component 3. In this way, the stability of the touch component 3 can be improved.

[0058] Please see Figure 8 The first piece 11, the second piece 12, the third piece 13, the first plate 21 and the second plate 22 enclose and form a receiving space 91. The third piece 13 is provided with a through 92 that communicates with the receiving space 91. The receiving space 91 is used to accommodate electronic components, and the through 92 is used for at least part of the electronic components to pass through.

[0059] This invention provides a lower frame structure 100, including a frame 1, a first support 2, a touch component 3, and a second support 4. The frame 1 includes a first piece 11, a second piece 12, and a third piece 13 connected in sequence. The first piece 11 and the third piece 13 are arranged opposite to each other.

The first clamping space is used to accommodate the glass cover plate 200. The second bracket 4 and the vertical wall of the step 31 of the touch component 3 jointly clamp the glass cover plate 200.

[0060] Compared to the traditional frame 1 with a rectangular or trapezoidal cross-section, the frame 1 of the present invention can reduce structural features and material costs through the above method. It only requires blanking and cutting processes, omitting processes such as flanging, thread pulling, forming and tapping, thereby improving processing efficiency.
