Description

Technical Field

[0001] The present invention relates to an input device, and particularly to a touchpad device. Background Art

[0002] A touchpad is a widely used input device for a computer, which is used to sense the movement or pressing of a user's finger to control the cursor to act (such as controlling cursor displacement or clicking, etc.).

[0003] The currently known touchpad structure has a touch plate and a substrate. The touch plate has a pivoting side and is pivotally fixed to the substrate with the pivoting side. When the part of the touch plate far from the pivoting side is pressed, the touch plate can swing and descend relative to the substrate with the pivoting side as the axis to generate corresponding signals.

[0004] However, during the process of the user operating the touch plate, the user does not necessarily press the part of the touch plate far from the pivoting side accurately. Therefore, when the user presses the pivoting side of the touch plate or the area or corner adjacent to the pivoting side, it will cause the touch plate to be unable to be stressed and descend smoothly, unable to generate corresponding signals, and cause problems such as operational troubles and affecting the operation feel. Summary of the Invention

[0005] In view of the above, in one embodiment, a touchpad device is provided, which includes a substrate, a circuit board, a reset member, an annular plate, a first linkage member and a second linkage member. The substrate includes a top surface. The circuit board is disposed above the top surface of the substrate, and the circuit board includes a bottom surface facing the top surface. The reset member is disposed between the substrate and the circuit board, and the reset member keeps the circuit board at a height position. The annular plate is fixed around the bottom surface of the circuit board. The annular plate includes an inner circumferential, and the inner circumferential includes a first side, a second side, a third side and a fourth side connected to each other. The first side and the second side are located on opposite sides, the third side and the fourth side are located on opposite sides, and a first limiting member is provided on the first side. The first linkage member and the second linkage member are disposed between the substrate and the circuit board, and the first linkage member and the second linkage member are respectively located on opposite sides of the reset member. The first linkage member includes a first swing plate. The first swing plate includes a first outer side and a first inner side. The first inner side is swingably connected to the substrate, the first outer side is adjacent to the first side, and the first outer side is clamped between the first limiting member and the circuit board.

[0006] In summary, according to the touchpad device of the embodiment of the present invention, by disposing the first linkage member and the second linkage member between the substrate and the touch plate, when any part (such as a corner or an edge) of the touchpad device is pressed, it can prompt the circuit board and the reset member to approach and press against each other, thereby generating a pressing feel. In addition, by clamping the first outer side of the first linkage member between the first limiting member of the annular plate and the circuit board, the situation of the first linkage member being displaced or shaken during actuation can be avoided, achieving the advantages of reducing noise during operation and improving the operation feel.

[0091] It should be noted that in the description of each embodiment, the so-called "first", "second", "third", and "fourth" are used to describe different elements, and these elements are not limited by such terms. In addition, for the convenience and clarity of description, the thickness or size of each element in the drawings is represented in an exaggerated, omitted, or schematic manner for the understanding and reading of those skilled in the art, and the size of each element is not completely its actual size, and it is not used to limit the implementable conditions of the present invention, so it does not have technical essence significance. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present invention. The same reference numerals will be used to represent the same or similar elements in all the drawings.

[0092] Figure 1 It is a schematic application diagram of the touchpad device of the present invention. Figure 2 It is an exploded perspective view of an embodiment of the touchpad device of the present invention. Figure 3 It is another exploded perspective view of an embodiment of the touchpad device of the present invention. Figure 4 It is a partial perspective view of an embodiment of the touchpad device of the present invention. Figure 5 It is a top view of an embodiment of the touchpad device of the present invention. As Figure 1 And Figure 2 shown, the touchpad device T (such as Touchpad or Trackpad) can be applied to computer products, and the user can operate the touchpad device T through actions such as finger sliding or pressing to control the displacement of the cursor or generate corresponding control signals. For example Figure 1 shown, in this embodiment, the touchpad device T is applied to a notebook computer N. However, this is not limited. In other embodiments, the touchpad device T can also be applied to other portable computers (such as tablet computers). Or, the touchpad device T can also be an independent device and externally connected to a portable computer, and this embodiment does not limit.

[0093] AsFigures 2 to 5 As shown in the figure, the touchpad device T includes a substrate 20, a circuit board 30, a reset member 40, an annular plate 50, a first linkage member 60, and a second linkage member 70. The substrate 20 can be a rigid plate made of metal (such as iron, aluminum, or alloy) or plastic. The substrate 20 has a top surface 21, and the circuit board 30, the reset member 40, the annular plate 50, the first linkage member 60, and the second linkage member 70 are all disposed above the top surface 21.

[0094] As Figures 2 to 5 shown, the circuit board 30 has a bottom surface 31, and the bottom surface 31 faces the top surface 21 of the substrate 20. In this embodiment, a trigger switch 32 is provided on the bottom surface 31 of the circuit board 30. For example, the trigger switch 32 can be a push-button switch or a microswitch. In some embodiments, the circuit board 30 can be various circuit boards such as a general printed circuit board (PCB), a flexible printed circuit board (FPCB), or a rigid-flex PCB.

[0095] As Figures 2 to 5 shown, the reset member 40 is disposed between the substrate 20 and the circuit board 30. The reset member 40 can be fixed (such as by adhesion, riveting, locking, or welding) to the top surface 21 of the substrate 20 or the bottom surface 31 of the circuit board 30, and the reset member 40 corresponds to the trigger switch 32. The reset member 40 can position the circuit board 30 at a height position and keep a distance from the substrate 20. In some embodiments, the above-mentioned reset member 40 can be a block (as Figure 2 shown, it can be a plastic block or a metal block) or a magnetic member, or the reset member 40 can also be an elastic body such as a rubber dome, a metal dome, a spring, or a spring sheet, so that the reset member 40 can accumulate elastic force when pressed.

[0096] Again, as Figures 2 to 5As shown in the figure, a touch panel P is stacked above the circuit board 30, and the circuit board 30 is closer to the substrate 20 than the touch panel P. Among them, the touch panel P can be a plate made of glass or polyester resin (mylar) for the user to touch or press. The circuit board 30 can generate functions such as scrolling, zooming in, zooming out, or opening a window in response to the user's finger sliding or gesture on the touch panel P. Or the circuit board 30 can generate functions such as selection or display of a menu in response to the user's finger pressing, clicking, or double-clicking on the touch panel P. For example, when the touch panel P is pressed and descends relative to the substrate 20, the reset member 40 and the trigger switch 32 can be pressed against each other to generate a signal. In addition, when the touch panel P is released, if the reset member 40 is an elastic body, the touch panel P can rise back to the above height position through the elastic force accumulated by the reset member 40. If the trigger switch 32 is a push-button switch, the touch panel P can rise back to the above height position by pressing against the reset member 40 through the elastic force accumulated by the trigger switch 32. In some embodiments, the above touch panel P and the circuit board 30 can also be integrated into the same plate. For example, the adjacent surfaces of the touch panel P and the circuit board 30 can be combined by means such as back glue, chemical glue (such as photo-curing glue), or physical glue (such as thermosetting adhesive or thermoplastic adhesive) to be integrated into the same plate.

[0097] As Figures 2 to 5 shown, the annular plate 50 is fixed around the bottom surface 31 of the circuit board 30. The annular plate 50 can be a rigid plate made of metal or plastic, and the annular plate 50 can be fixed to the bottom surface 31 of the circuit board 30 by means such as cementing, riveting, locking, or welding.

[0098] As Figures 2 to 5 shown, the annular plate 50 includes an inner circumferential portion 51. The inner circumferential portion 51 includes a first side 52, a second side 53, a third side 54, and a fourth side 55 that are connected to each other. The first side 52 and the second side 53 are located on opposite sides, the third side 54 and the fourth side 55 are located on opposite sides, and at least one first limiting member 521 is provided on the first side 52 of the annular plate 50, and at least one second limiting member 531 is provided on the second side 53. For example, in this embodiment, three first limiting members 521 are provided on the first side 52 at intervals, and three second limiting members 531 are provided on the second side 53 at intervals. However, the above numbers of the first limiting member 521 and the second limiting member 531 are only examples and are not actually limited thereto.

[0099] Figure 6 For Figure 5 a cross-sectional view along line 6-6, please refer to Figure 3 and Figure 6As shown, in this embodiment, the first limiting member 521 is a plate member integrally extending from the first side 52 of the annular plate 50. The first limiting member 521 includes a first connecting plate 5211 and a first limiting plate 5212. The first limiting plate 5212 and the bottom surface 31 of the circuit board 30 are spaced apart from each other. The first connecting plate 5211 is a bent plate and is connected between one end of the first limiting plate 5212 and the first side 52, such that the first limiting member 521 as a whole is an L-shaped plate member. The second limiting member 531 may also be a plate member integrally extending from the second side 53 of the annular plate 50. The structure of the second limiting member 531 may be the same as or similar to that of the first limiting member 521, and thus will not be repeated here.

[0100] As Figures 2 to 4 shown, the first linkage 60 and the second linkage 70 are disposed between the substrate 20 and the circuit board 30 and are respectively located on opposite sides of the reset member 40. The first linkage 60 and the second linkage 70 are used to guide the lifting displacement of the touch pressing plate P and the circuit board 30 relative to the substrate 20. Herein, the first linkage 60 and the second linkage 70 are symmetrically disposed with respect to the reset member 40 as the center, but this is not limiting. The first linkage 60 includes a first flexible sheet 61 and a first swing plate 65. The second linkage 70 also includes a second flexible sheet 71 and a second swing plate 75. In some embodiments, the shapes of the above-mentioned first flexible sheet 61, first swing plate 65, second flexible sheet 71, and second swing plate 75 may be rectangular, triangular, trapezoidal, polygonal, H-shaped, U-shaped, or other irregular shapes.

[0101] As Figures 2 to 4 shown, the first swing plate 65 of the first linkage 60 includes a first outer side 66 and a first inner side 67. The first inner side 67 is closer to the reset member 40 than the first outer side 66. Among them, the first inner side 67 is swingably connected to the substrate 20. The first outer side 66 is adjacent to the first side 52 of the annular plate 50. The first flexible sheet 61 is connected between the first outer side 66 and the annular plate 50. The second swing plate 75 of the second linkage 70 includes a second outer side 76 and a second inner side 77. The second inner side 77 is closer to the reset member 40 than the second outer side 76. The second inner side 77 is swingably connected to the substrate 20. The second outer side 76 is adjacent to the second side 53 of the annular plate 50. The second flexible sheet 71 is connected between the second outer side 76 and the annular plate 50.

[0102] In some embodiments, the first flexible sheet 61 and the second flexible sheet 71 may be flexible elastic thin sheets made of plastic or metal, and the rigidity of the first swing plate 65 and the second swing plate 75 may be greater than that of the first flexible sheet 61 and the second flexible sheet 71. Thereby, the first swing plate 65 and the second swing plate 75 can move relative to the pressure contact plate P through the flexibility of the first flexible sheet 61 and the second flexible sheet 71. In addition, when the first flexible sheet 61 and the second flexible sheet 71 are made of plastic, they can be fixed to other components by adhesion. When the first flexible sheet 61 and the second flexible sheet 71 are made of metal, they can be fixed to other components by adhesion, welding, riveting or other means, but this is not limited thereto.

[0103] As Figures 2 to 4 shown, in this embodiment, at least one first hook 671 is provided on the first inner side 67 of the first swing plate 65. Here, the number of the first hooks 671 is two and they are integrally bent out from the first inner side 67 (here, the first hooks 671 are in an L shape). A first hook seat 211 corresponding to the first hook 671 is provided on the top surface 21 of the substrate 20, and the number of the first hook seats 211 corresponds to the number of the first hooks 671. Here, the first hook seat 211 is integrally bent from the substrate 20 and protrudes from the top surface 21. The first hook seat 211 may be a U-shaped hook seat (as Figure 3 shown), an L-shaped hook seat, a T-shaped hook seat or a hook seat of other shapes, which is not limited thereto. Each first hook 671 of the first swing plate 65 is hooked to each first hook seat 211, so that the first inner side 67 of the first swing plate 65 is swingably connected to the substrate 20. At least one second hook 771 is also provided on the second inner side 77 of the second swing plate 75. A second hook seat 212 corresponding to the second hook 771 is provided on the top surface 21 of the substrate 20, and the number of the second hook seats 212 corresponds to the number of the second hooks 771. And the second hook 771 of the second swing plate 75 is hooked to the second hook seat 212, so that the second inner side 77 of the second swing plate 75 is swingably connected to the substrate 20. The structures of the second hook 771 and the second hook seat 212 may be the same as or similar to the structures of the first hook 671 and the first hook seat 211 respectively, and will not be repeated here.

[0104] As Figures 2 to 4 and Figure 6As shown, a first limiting portion 661 corresponding to the first limiting member 521 is further provided on the first outer side 66 of the first swing plate 65. The number of the first limiting portions 661 corresponds to the number of the first limiting members 521. And each first limiting portion 661 is clamped between each first limiting member 521 and the circuit board 30. For example, in this embodiment, each first limiting portion 661 is a plate member and integrally extends from the first outer side 66, and each first limiting portion 661 is clamped between the first limiting plate 5212 of each first limiting member 521 and the bottom surface 31 of the circuit board 30. Similarly, a second limiting portion 761 corresponding to the second limiting member 531 can be provided on the second outer side 76 of the second swing plate 75. The number of the second limiting portions 761 corresponds to the number of the second limiting members 531. Each second limiting portion 761 can also be a plate member and integrally extends from the second outer side 76, and each second limiting portion 761 is clamped between each second limiting member 531 and the bottom surface 31 of the circuit board 30.

[0105] Thereby, when any part of the touch pressure plate P (such as each corner or each edge of the touch pressure plate P) is pressed, the trigger switch 32 of the circuit board 30 and the reset member 40 can be mutually approximated and pressed through the first linkage 60 and the second linkage 70, so as to generate a signal and a pressing feel. Please refer to Figure 6 and Figure 7 shown in Figure 7 is Figure 6 the pressure-actuated diagram of Figure 7 In this embodiment, when a corner, an edge or a region of the touch pressure plate P close to the first linkage 60 is pressed (as shown by the arrow L in Figure 7 ), the touch pressure plate P can be driven by the first linkage 60 to descend and approach the top surface 21 of the substrate 20. Specifically, the pressing force on the touch pressure plate P can be transmitted to the first inner side 67 through the first flexible sheet 61 to drive the first swing plate 65, so that the first swing plate 65 can swing relative to the substrate 20 with the first inner side 67 as a fulcrum and based on the foldability of the first flexible sheet 61, so as to drive the touch pressure plate P to descend and approach the top surface 21 of the substrate 20 to trigger the above-mentioned trigger switch 32 to generate a signal. Similarly, when a corner, an edge or a region of the touch pressure plate P close to the second linkage 70 is pressed, the pressing force can drive the second swing plate 75 of the second linkage 70 to swing, so as to drive the touch pressure plate P to descend and approach the substrate 20 to trigger the generation of a signal, which will not be repeated here. It can be seen from the above description that when any side or corner of the touch pressure plate P is pressed, it can be lifted and lowered more stably through the linkage of the first linkage 60 and the second linkage 70, effectively preventing noise and shaking during operation and improving the operation feel.

[0106] In addition, as shown in Figure 3 , Figure 4 and Figure 7As shown, during the swinging process of the first swing plate 65 and the second swing plate 75, the first limiting portion 661 on the first outer side 66 of the first swing plate 65 is clamped between the first limiting member 521 and the bottom surface 31 of the circuit board 30, and the second limiting portion 761 on the second outer side 76 of the second swing plate 75 is clamped between the second limiting member 531 and the bottom surface 31 of the circuit board 30. This can effectively prevent the first linkage member 60 and the second linkage member 70 from being displaced or shaken during operation, achieving the advantages of reducing noise during operation and improving the operating feel.

[0107] As Figures 2 to 4 shown, in this embodiment, the touchpad device T further includes a third linkage member 80 and a fourth linkage member 90. The third linkage member 80 and the fourth linkage member 90 are disposed between the substrate 20 and the circuit board 30 and are respectively adjacent to the third side 54 and the fourth side 55 of the annular plate 50. The third linkage member 80 and the fourth linkage member 90 are used to guide the touch plate P and the circuit board 30 to perform lifting displacement relative to the substrate 20. Here, the third linkage member 80 and the fourth linkage member 90 are symmetrically arranged with respect to the reset member 40 as the center, but this is not limited. Specifically, the four sides of the annular plate 50 are respectively connected to the first linkage member 60, the second linkage member 70, the third linkage member 80, and the fourth linkage member 90. When any side or corner of the touch plate P is pressed, it can be further lifted and lowered more stably through the linkage of the third linkage member 80 and the fourth linkage member 90, more effectively preventing noise and shaking during operation and improving the operating feel.

[0108] As Figures 1 to 4 shown, the third linkage member 80 includes a third flexible sheet 81 and a third swing plate 85, and the fourth linkage member 90 also includes a fourth flexible sheet 91 and a fourth swing plate 95. In this embodiment, the third swing plate 85 and the fourth swing plate 95 are long plates, which are different from the shapes of the above-mentioned first swing plate 65 and second swing plate 75, but this is not limited. In some embodiments, the shapes of the above-mentioned third flexible sheet 81, third swing plate 85, fourth flexible sheet 91, and fourth swing plate 95 can be rectangular, triangular, trapezoidal, polygonal, H-shaped, U-shaped, or other irregular shapes.

[0109] As Figures 2 to 4As shown, the third swing plate 85 of the third linkage 80 includes a third outer side 86 and a third inner side 87. The third inner side 87 is closer to the reset member 40 than the third outer side 86. The third inner side 87 is swingably connected to the substrate 20. The third outer side 86 is adjacent to the third side 54 of the annular plate 50. The third flexible sheet 81 is connected between the third outer side 86 and the annular plate 50. The fourth swing plate 95 of the fourth linkage 90 includes a fourth outer side 96 and a fourth inner side 97. The fourth inner side 97 is closer to the reset member 40 than the fourth outer side 96. The fourth inner side 97 is swingably connected to the substrate 20. The fourth outer side 96 is adjacent to the fourth side 55 of the annular plate 50. The fourth flexible sheet 91 is connected between the fourth outer side 96 and the annular plate 50.

[0110] In some embodiments, the above-mentioned third flexible sheet 81 and fourth flexible sheet 91 can be flexible elastic thin sheets made of plastic or metal. The rigidity of the third swing plate 85 and the fourth swing plate 95 can be greater than that of the third flexible sheet 81 and the fourth flexible sheet 91. Thus, the third swing plate 85 and the fourth swing plate 95 can move relative to the pressure contact plate P through the flexibility of the third flexible sheet 81 and the fourth flexible sheet 91. The actuation modes of the third linkage 80 and the fourth linkage 90 can be the same as those of the first linkage 60 and the second linkage 70 mentioned above, and will not be repeated here.

[0111] As Figures 2 to 4 shown, in this embodiment, at least one third limiting member 541 is provided on the third side 54 of the annular plate 50, and at least one fourth limiting member 551 is provided on the fourth side 55. For example, in this embodiment, five third limiting members 541 are provided on the third side 54 at intervals, and five fourth limiting members 551 are provided on the fourth side 55 at intervals. However, the numbers of the above-mentioned third limiting member 541 and fourth limiting member 551 are only examples, and actually are not limited thereto.

[0112] Figure 8 For Figure 5 the cross-sectional view along line 8-8, in this embodiment, the third limiting member 541 is a plate member integrally extending from the third side 54. The third limiting member 541 includes a third connecting plate 5411 and a third limiting plate 5412. The third limiting plate 5412 and the bottom surface 31 of the circuit board 30 are spaced apart from each other. The third connecting plate 5411 is a bent plate and is connected between one end of the third limiting plate 5412 and the third side 54, so that the third limiting member 541 as a whole is an L-shaped plate member. The fourth limiting member 551 can also be a plate member integrally extending from the fourth side 55. The structure of the fourth limiting member 551 can be the same as or similar to that of the third limiting member 541, and will not be repeated here.

[0113] Again, as Figures 2 to 4As shown, in this embodiment, at least one third hook 871 is provided on the third inner side 87 of the third swing plate 85, and at least one fourth hook 971 is also provided on the fourth inner side 97 of the fourth swing plate 95. On the top surface 21 of the substrate 20, a third hook seat 213 corresponding to the third hook 871 and a fourth hook seat 214 corresponding to the fourth hook 971 are provided. The number of the third hook seats 213 corresponds to the number of the third hooks 871, and the number of the fourth hook seats 214 corresponds to the number of the fourth hooks 971. The third hook 871 of the third swing plate 85 is hooked to the third hook seat 213, so that the third inner side 87 of the third swing plate 85 is swingably connected to the substrate 20. The fourth hook 971 of the fourth swing plate 95 is hooked to the fourth hook seat 214, so that the fourth inner side 97 of the fourth swing plate 95 is swingably connected to the substrate 20. Among them, the structures of the third hook 871 and the fourth hook 971 can be the same as or similar to the structures of the above-mentioned first hook 671 and second hook 771, and the structures of the third hook seat 213 and the fourth hook seat 214 can be the same as or similar to the structures of the above-mentioned first hook seat 211 and second hook seat 212, and thus will not be repeated here.

[0114] As Figures 2 to 4 shown, a third limiting portion 861 corresponding to the third limiting member 541 is further provided on the third outer side 86 of the third swing plate 85. Similarly, a fourth limiting portion 961 corresponding to the fourth limiting member 551 can be provided on the fourth outer side 96 of the fourth swing plate 95. The number of the third limiting portions 861 corresponds to the number of the third limiting members 541, and the number of the fourth limiting portions 961 corresponds to the number of the fourth limiting members 551. The third limiting portion 861 is clamped between the third limiting member 541 and the circuit board 30, and the fourth limiting portion 961 is clamped between the fourth limiting member 551 and the bottom surface 31 of the circuit board 30, so as to effectively prevent the third linkage 80 and the fourth linkage 90 from being displaced or shaken during operation, achieving the advantages of reducing the noise during operation and improving the operation feel. In some embodiments, the structures of the above-mentioned third limiting portion 861 and fourth limiting portion 961 can be the same as or similar to the structures of the above-mentioned first limiting portion 661 and second limiting portion 761, and thus will not be repeated here.

[0115] Figure 9 is Figure 2 a partial enlarged perspective view of the region 9, Figure 10 is Figure 9 a partial cross-sectional view, Figure 11 is Figure 5 a cross-sectional view along the line 11-11, Figure 12 is Figure 5 a cross-sectional view along the line 12-12. Please refer to Figure 4 , Figures 9 to 12As shown, in this embodiment, at least one first elastic arm 672 is further provided on the first inner side 67 of the first swing plate 65 of the first linkage 60. Here, the number of the first elastic arms 672 is two and they extend integrally from the first inner side 67, and the end portions of the first elastic arms 672 abut against the top surface 21 of the substrate 20 (as Figure 11 shown), which can eliminate the tolerance gap between the first linkage 60 and the substrate 20, avoid shaking or vibration caused by the tolerance gap when the touch pressure plate P is pressed, and thus further improve the operation feel of the touch panel device T. In addition, as Figure 10 shown, in this embodiment, the end portion of the first elastic arm 672 further has a bump 673, and the first elastic arm 672 abuts against the top surface 21 of the substrate 20 with the bump 673, which can reduce the interference area between the first elastic arm 672 and the substrate 20 and avoid excessive resistance when the first linkage 60 operates.

[0116] In addition, as Figure 4 shown, at least one second elastic arm 772 can also be provided on the second inner side 77 of the second swing plate 75 of the second linkage 70 to abut against the top surface 21 of the substrate 20, and at least one third elastic arm 872 can also be provided on the third inner side 87 of the third swing plate 85 of the third linkage 80 to abut against the top surface 21 of the substrate 20 (as Figure 12 shown), and at least one fourth elastic arm 972 can also be provided on the fourth outer side 96 of the fourth swing plate 95 of the fourth linkage 90 to abut against the top surface 21 of the substrate 20, so as to eliminate the tolerance gap between the second linkage 70, the third linkage 80 and the fourth linkage 90 and the substrate 20, and avoid shaking or vibration caused by the tolerance gap when the touch pressure plate P is pressed.

[0117] Furthermore, as Figures 2 to 4 and Figure 6 shown, in this embodiment, the touch panel device T further includes a flexible plate 26. The flexible plate 26 can be an elastic thin plate made of plastic or metal with flexibility, and the flexible plate 26 is connected between the first inner side 67 of the first swing plate 65, the second inner side 77 of the second swing plate 75, the third inner side 87 of the third swing plate 85, the fourth inner side 97 of the fourth swing plate 95 and the substrate 20 to strengthen the limiting effect of the first swing plate 65, the second swing plate 75, the third swing plate 85 and the fourth swing plate 95. In addition, in this embodiment, the reset member 40 is fixed on the flexible plate 26. For example, the reset member 40 can be fixed on the surface of the flexible plate 26 by adhesion, but this is not limited.

[0118] Figure 13 is an exploded perspective view of another embodiment of the touch panel device of the present invention. As Figure 13As shown, in this embodiment, the substrate 20 is further provided with a reinforcing structure 25, and the reinforcing structure 25 is adjacent to the reset member 40. The reinforcing structure 25 can be at least one folding plate 251 and is integrally bent from the substrate 20. Here, the number of folding plates 251 is two and they are respectively located on opposite sides of the reset member 40. For example, the folding plates 251 can be formed by stamping or drawing the substrate 20. Thereby, the reinforcing structure 25 can strengthen the structural strength of the area of the substrate 20 near the reset member 40 to prevent the deformation of this area due to force and affect the triggering effect of the trigger switch 32 or the operating feel of the user. In addition, in this embodiment, the length of the reinforcing structure 25 is also greater than the length of the reset member 40, so that a better structural reinforcement effect can be obtained for the area of the substrate 20 near the reset member 40.

[0119] Again, Figure 13 As shown, the substrate 20 is further provided with at least one fixing portion 22 and at least one hollow hole 23. In this embodiment, the number of fixing portions 22 is multiple and they are located around the substrate 20 for assembling and fixing to the surrounding frames 100, 101. For example, the frames 100, 101 can be part of the housing of the touch panel device T. The number of hollow holes 23 is also multiple and they are located between the multiple fixing portions 22 and the reset member 40. Thereby, if deformation occurs in the fixing portion 22 or the area of the substrate 20 adjacent to the fixing portion 22 after the fixing portion 22 is fixed to the frames 100, 101, the hollow holes 23 can prevent the above deformation from affecting the area of the substrate 20 near the reset member 40, so that the area of the substrate 20 near the reset member 40 can remain flat and avoid affecting the triggering effect.

[0120] Figure 14 is Figure 13 a cross-sectional view along line segment 14-14. Please refer to Figure 13 and Figure 14 As shown, the substrate 20 is further provided with at least one elastic arm 24. Here, the number of elastic arms 24 is multiple and they are respectively located in the multiple hollow holes 23, and the end portions of each elastic arm 24 abut against the frame 101 on which the substrate 20 is mounted. For example, the end portions of each elastic arm 24 can directly abut against the frame 101 or indirectly abut against the frame 101 through the elastic body 241. Thereby, since the elastic arms 24 are integrally connected to the area of the substrate 20 near the reset member 40, the rigidity of the area of the substrate 20 near the reset member 40 can be enhanced, so that the trigger switch 32 of the circuit board 30 can be triggered faster after the touch plate P is pressed and has a better pressing feel.
