Description

Technical Field

[0001] The present invention relates to an input device, and more 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 and other actions).

[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 downward 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 not be able to be pressed down smoothly and not 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 receiving board, a reset member, a triggering member, a first balance bar, a second balance bar, a first swing plate and a second swing plate. The substrate includes a top surface. The circuit board is disposed above the top surface of the substrate. The circuit board includes a bottom surface facing the top surface, and a triggering switch is provided on the bottom surface. The receiving board is fixed to the bottom surface of the circuit board. The receiving board includes a first side, a second side, a third side and a fourth side that are 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 the receiving board has a hollow hole corresponding to the triggering switch. The reset member is disposed between the substrate and the circuit board. The triggering member is disposed between the substrate and the circuit board and corresponds to the hollow hole. The first balance bar is disposed between the first side and the substrate, and the second balance bar is disposed between the second side and the substrate. The first swing plate and the second swing plate are disposed between the substrate and the circuit board. The first swing plate is connected between the third side and the triggering member, and the second swing plate is connected between the fourth side and the triggering member. The first swing plate and the second swing plate can be pressed to swing relative to the substrate to drive the triggering member to move upward toward the triggering switch.

[0006] In summary, for the touchpad device according to the embodiments of the present invention, the first balance bar and the second balance bar are respectively connected to the first side and the second side of the receiving plate, and the first swing plate and the second swing plate can swing relative to the substrate under pressure to drive the trigger member to move upward toward the trigger switch. When any part of the touchpad device (such as the corners or edges of the touch plate) is pressed, it can cause the circuit board and the trigger member to approach each other and press the trigger switch to trigger the generation of a signal, which can greatly reduce the dead travel and provide a good pressing feel.

[0075] Figure 1 FIG. is a schematic application diagram of an embodiment of the touchpad device of the present invention. Figure 2 FIG. is an exploded perspective view of an embodiment of the touchpad device of the present invention. Figure 3 FIG. is another exploded perspective view of an embodiment of the touchpad device of the present invention. Figure 4 FIG. is a top view of an embodiment of the touchpad device of the present invention. Figure 5 is Figure 4 A cross-sectional view taken along line 5-5. As Figure 1 and Figure 2 shown, the touchpad device 1 can be applied to computer products, and the user can operate the touchpad device 1 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 1 is applied to a notebook computer N. However, this is not limited. In other embodiments, the touchpad device 1 can also be applied to other portable computers (such as tablet computers). Or, the touchpad device 1 can also be an independent device and externally connected to a portable computer, and this embodiment is not limited.

[0076] As Figures 2 to 5 shown, the touchpad device 1 includes a substrate 10, a circuit board 20, a receiving board 30, a reset member 40, a trigger member 50, a first balance bar 61, a second balance bar 62, a first swing plate 71, and a second swing plate 72. Among them, the substrate 10 can be a rigid plate made of metal (such as iron, aluminum, or alloy, etc.) or plastic material, and the substrate 10 has a top surface 11. The circuit board 20, the receiving board 30, the reset member 40, the trigger member 50, the first balance bar 61, the second balance bar 62, the first swing plate 71, and the second swing plate 72 are all disposed above the top surface 11.

[0077] As Figures 2 to 5As shown, the circuit board 20 has a bottom surface 21 facing the top surface 11 of the substrate 10. In this embodiment, a trigger switch 22 is provided at the center of the bottom surface 21 of the circuit board 20. For example, the trigger switch 22 can be a push-button switch or a microswitch, but this is not limited. The trigger switch 22 can also be provided at other positions on the bottom surface 21. In some embodiments, the circuit board 20 can be various circuit boards such as a general printed circuit board (PCB), a flexible printed circuit board (FPCB), or a rigid-flex PCB.

[0078] As Figures 2 to 5 shown, the receiving plate 30 is fixed to the bottom surface 21 of the circuit board 20. The receiving plate 30 can be a rigid plate body made of metal or plastic, and the receiving plate 30 can be fixed to the bottom surface 21 of the circuit board 20 by means such as adhesion, riveting, locking, or welding. The outer circumference of the receiving plate 30 includes a first side 31, a second side 32, a third side 33, and a fourth side 34 that are connected to each other. The first side 31 and the second side 32 are located on opposite sides, and the third side 33 and the fourth side 34 are located on opposite sides. The lengths of the first side 31 and the second side 32 are greater than or equal to the lengths of the third side 33 and the fourth side 34, but this is not limited. In addition, the receiving plate 30 further has a hollow hole 35 that penetrates the opposite two surfaces of the receiving plate 30 and corresponds to the trigger switch 22.

[0079] As Figures 2 to 5 shown, the reset member 40 is disposed between the substrate 10 and the circuit board 20. The reset member 40 can be fixed (such as by adhesion, riveting, locking, or welding) to the top surface 11 of the substrate 10 or the bottom surface 21 of the circuit board 20, and the reset member 40 corresponds to the trigger switch 22. The reset member 40 can keep the circuit board 20 and the receiving plate 30 at a height position and maintain a distance from the substrate 10. 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 plastic dome, a spring, or a spring piece, so that the reset member 40 can accumulate elastic force when pressed.

[0080] Again, as Figures 2 to 5As shown in the figure, a touch plate P is stacked above the circuit board 20, and the circuit board 20 is closer to the substrate 10 relative to the touch plate P. Among them, the touch plate P can be a plate made of glass or polyester resin (mylar) for the user to touch or press. The circuit board 20 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 plate P. Or the circuit board 20 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 plate P. For example, when the touch plate P is pressed and descends relative to the substrate 10, the reset member 40 and the trigger switch 22 can be pressed against each other to generate a signal. In addition, when the touch plate P is released, if the reset member 40 is an elastic body, the touch plate P can rise back to the above height position through the elastic force accumulated by the reset member 40. If the trigger switch 22 is a push-button switch, the touch plate 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 22.

[0081] As Figure 5 shown, in this embodiment, the reset member 40 is a metal dome and has elasticity. The trigger switch 22 is a trigger point provided on the bottom surface 21 of the circuit board 20. When the touch plate P is pressed and descends relative to the substrate 10, it can press the reset member 40 to collapse and touch and trigger the trigger switch 22, and accumulate elastic force. When the touch plate P is released, the touch plate P can rise back to the above height position through the elastic force accumulated by the reset member 40 (metal dome). However, this is not limited. In some embodiments, the reset member 40 and the trigger switch 22 can also be other different combinations. For example, the trigger switch 22 can be a push-button switch or a microswitch and has elasticity, the reset member 40 can be a non-elastic block, or the reset member 40 can also be an elastic rubber dome, spring, or elastic sheet.

[0082] In some embodiments, the above touch plate P and the circuit board 20 can also be integrated into the same plate. For example, the adjacent surfaces of the touch plate P and the circuit board 20 can be combined by means such as back glue, chemical glue (such as photo-curing glue), or physical glue (such as thermosetting glue or thermoplastic glue) to be integrated into the same plate.

[0083] As Figures 2 to 5 shown, the trigger member 50 is disposed between the substrate 10 and the circuit board 20 and corresponds to the hollow hole 35. In this embodiment, the trigger member 50 is a plate member and is located in the hollow hole 35 to correspond to the hollow hole 35, but this is not limited. In some embodiments, the trigger member 50 can also be located above or below the hollow hole 35, and the trigger member 50 can be a rigid plate made of metal or plastic. Further, the reset member 40 can be disposed between the trigger member 50 and the circuit board 20.

[0084] As Figure 3 andFigure 4 As shown in the figure, the first balance bar 61 includes a first rotating shaft 611 and two first side bars 612 respectively connected to both ends of the first rotating shaft 611. In this embodiment, the two first side bars 612 are substantially perpendicular to the first rotating shaft 611. The first rotating shaft 611 is arranged along the first side 31 of the receiving plate 30 and can rotate relative to the receiving plate 30. Here, a first long groove 381 is provided on the first side 31 of the receiving plate 30, and the first rotating shaft 611 of the first balance bar 61 is pivotally arranged in the first long groove 381. Each first side bar 612 of the first balance bar 61 is movably connected to the substrate 10. In this embodiment, two first connecting members 102 are protruded from the substrate 10 and arranged at intervals for connecting the two first side bars 612. Each of the first connecting members 102 is a hook seat integrally bent and extended upward from the substrate 10 (here it is a U-shaped hook seat, but it can also be a hook seat of other shapes such as an L-shaped or T-shaped one), and the end parts of the two first side bars 612 are respectively inserted into the two first connecting members 102. Thus, when the pressure plate P is pressed and descends towards the substrate 10, the first rotating shaft 611 can rotate relative to the receiving plate 30, and the end parts of the first side bars 612 can slide relative to the first connecting members 102, so that each first side bar 612 swings relative to the substrate 10.

[0085] As Figure 3 shown Figure 4 As shown in the figure, the second balance bar 62 includes a second rotating shaft 621 and two second side bars 622 respectively connected to both ends of the second rotating shaft 621. In this embodiment, the two second side bars 622 are substantially perpendicular to the second rotating shaft 621. The second rotating shaft 621 is arranged along the second side 32 of the receiving plate 30 and can rotate relative to the receiving plate 30. Here, a second long groove 382 is provided on the second side 32 of the receiving plate 30, and the second rotating shaft 621 of the second balance bar 62 is pivotally arranged in the second long groove 382. Each second side bar 622 of the second balance bar 62 is movably connected to the substrate 10. In this embodiment, two second connecting members 103 are protruded from the substrate 10 and arranged at intervals for connecting the two second side bars 622. Each of the second connecting members 103 is a hook seat integrally bent and extended upward from the substrate 10 (here it is a U-shaped hook seat, but it can also be a hook seat of other shapes such as an L-shaped or T-shaped one), and the end parts of the two second side bars 622 are respectively inserted into the two second connecting members 103. Thus, when the pressure plate P is pressed and descends towards the substrate 10, the second rotating shaft 621 can rotate relative to the receiving plate 30, and the end parts of the second side bars 622 can slide relative to the second connecting members 103, so that each second side bar 622 swings relative to the substrate 10.

[0086] As Figures 2 to 5As shown, the first swing plate 71 and the second swing plate 72 are disposed between the substrate 10 and the circuit board 20. The first swing plate 71 is connected between the third side 31 and the trigger member 50, and the second swing plate 72 is connected between the fourth side 34 and the trigger member 50. In addition, when the first swing plate 71 and the second swing plate 72 are pressed, they can swing relative to the substrate 10 and drive the trigger member 50 to move upward toward the circuit board 20 to press against the trigger switch 22.

[0087] As Figures 2 to 5 shown, in this embodiment, the first swing plate 71 includes a first outer side 711 and a first inner side 712. The first outer side 711 is closer to the third side 31 of the receiving plate 30 than the first inner side 712. The first inner side 712 abuts against the bottom of the trigger member 50. A first flexible sheet 715 is connected between the first outer side 711 of the first swing plate 71 and the receiving plate 30. Therefore, when the first swing plate 71 swings, the first inner side 712 can abut against the trigger member 50 to move upward. The second swing plate 72 includes a second outer side 721 and a second inner side 722. The second outer side 721 is closer to the fourth side 34 of the receiving plate 30 than the second inner side 722. The second inner side 722 abuts against the bottom of the trigger member 50. A second flexible sheet 725 is further connected between the second outer side 721 of the second swing plate 72 and the receiving plate 30. Therefore, when the second swing plate 72 swings, the second inner side 722 can abut against the trigger member 50 to move upward. In some embodiments, the shapes of the first swing plate 71, the first flexible sheet 715, the second swing plate 72, and the second flexible sheet 725 may be rectangular, triangular, trapezoidal, polygonal, H-shaped, U-shaped, or other irregular shapes.

[0088] Continuing from the above, the first flexible sheet 715 and the second flexible sheet 725 may be flexible elastic thin plates made of plastic or metal. The first swing plate 71 and the second swing plate 72 may be rigid plates made of plastic or metal, but this is not limited. In addition, the rigidity of the first swing plate 71 and the second swing plate 72 is greater than that of the first flexible sheet 715 and the second flexible sheet 725. For example, the thickness of the first swing plate 71 and the second swing plate 72 may be greater than the thickness of the first flexible sheet 715 and the second flexible sheet 725. Thus, the first outer side 711 of the first swing plate 71 can swing relative to the receiving plate 30 through the flexibility of the first flexible sheet 715, and the second outer side 721 of the second swing plate 72 can swing relative to the receiving plate 30 through the flexibility of the second flexible sheet 725.

[0089] In some embodiments, when the first flexible sheet 715 and the second flexible sheet 725 are made of plastic, they can be fixed to other components by adhesion. When the first flexible sheet 715 and the second flexible sheet 725 are made of metal, they can be fixed to other components by adhesion, welding, riveting, etc., but this is not limited.

[0090] Thereby, as Figures 2 to 5 shown, in the embodiment of the present invention, by arranging the first rotating shaft 611 of the first balance bar 61 along the first side 31 of the receiving plate 30 and the second rotating shaft 621 of the second balance bar 62 along the second side 32, it is possible to increase the rigidity of the corners and the surrounding of the touchpad device 1, so that when each corner or each edge of the pressure plate P is pressed, other components can be quickly linked through the first balance bar 61 and the second balance bar 62, thereby greatly reducing the dead travel when the pressure plate P is pressed and avoiding situations such as shaking and bending of the pressure plate P during the actuation process.

[0091] Again, as Figure 3 shown in Figure 4 In this embodiment, the receiving plate 30 includes a main board 37 and a ring frame 38 connected to the periphery of the main board 37. The main board 37 abuts against the bottom surface 21 of the circuit board 20. The thickness of the ring frame 38 is greater than that of the main board 37, and the ring frame 38 abuts against the periphery of the circuit board 20, so that the circuit board 20 is accommodated in the receiving plate 30 to reduce the overall thickness of the touchpad device 1. In addition, the first long groove 381 and the second long groove 382 are provided at the bottom of the ring frame 38 with a larger thickness to pivotally support the first rotating shaft 611 of the first balance bar 61 and the second rotating shaft 621 of the second balance bar 62 respectively, so that the first balance bar 61 and the second balance bar 62 can adopt a larger rod diameter to improve the overall structural rigidity, which is more conducive to the force transmission when the corners or edges of the pressure plate P are pressed.

[0092] Again, as Figure 3 shown in Figure 4 In this embodiment, both ends of the first rotating shaft 611 of the first balance bar 61 extend to the third side 33 and the fourth side 34 of the receiving plate 30, so that the two first side bars 612 of the first balance bar 61 can be closer to the third side 33 and the fourth side 34 respectively. Both ends of the second rotating shaft 621 of the second balance bar 62 extend to the third side 33 and the fourth side 34 of the receiving plate 30, so that the second side bars 622 of the second balance bar 62 can also be closer to the third side 33 and the fourth side 34 respectively. Thereby, it is possible to further improve the rigidity of the corners and the surrounding of the pressure plate P, so that when the corners or edges of the pressure plate P are pressed, the transmission of the pressing force can be strengthened to improve the linkage effect.

[0093] In addition, in the embodiment of the present invention, the first swing plate 71 is connected between the third side 31 of the receiving plate 30 and the trigger member 50, and the second swing plate 72 is connected between the fourth side 34 of the receiving plate 30 and the trigger member 50. Moreover, when the first swing plate 71 and the second swing plate 72 are pressed, they can drive the trigger member 50 to move upward toward the trigger switch 22, which can further strengthen the linkage effect of the pressure on the corners and edges of the pressure plate P and can accelerate the trigger switch 22 of the trigger circuit board 20 to shorten the pressing stroke, which is described in detail as follows.

[0094] Please refer to Figure 3 、 Figure 5 and Figure 6 as shown, where Figure 6 is Figure 5 the compression actuation diagram of Figure 5 . In this embodiment, when the corner, edge or area where the touch plate P approaches is pressed (as shown by the arrow L in Figure 5 , here it is the area where the touch plate P approaches the third side 33 that is pressed), the pressing force can be quickly transmitted in the direction of the fourth side 34 via the first balance bar 61 and the second balance bar 62 to drive other components in conjunction, and the pressing force can drive the first swing plate 71 to swing relative to the substrate 10 via the first flexible sheet 715, so that the first inner side 712 of the first swing plate 71 rises towards the circuit board 20 to synchronously drive the trigger member 50 to rise and move towards the trigger switch 22, causing the trigger member 50 to press against the reset member 40 to collapse, thereby accelerating the triggering of the trigger switch 22 of the circuit board 20 and significantly shortening the pressing stroke. Similarly, when the corner, edge or area where the touch plate P approaches the fourth side 34 is pressed, the pressing force can drive the second swing plate 72 to swing relative to the substrate 10 via the second flexible sheet 725, so that the second inner side 722 of the second swing plate 72 rises towards the circuit board 20 to synchronously drive the trigger member 50 to rise and move towards the trigger switch 22, causing the trigger member 50 to press against the reset member 40 to collapse, thereby accelerating the triggering of the trigger switch 22 of the circuit board 20 and significantly shortening the pressing stroke. In addition, when the touch plate P is released, the elastic force accumulated by the reset member 40 can be used to push against the trigger member 50 to descend, driving the touch plate P to rise and return to the non-pressed position (i.e., the above-mentioned height position).

[0095] As can be seen from the above description, when any side or corner of the touch plate P is pressed, it can be stably lifted and lowered through the linkage of the first swing plate 71, the second swing plate 72, the first balance bar 61 and the second balance bar 62, and can significantly reduce the dead stroke when the touch plate P is pressed, avoid situations such as shaking and bending of the touch plate P during the actuation process, strengthen the linkage effect of the corners and edges of the touch plate P being pressed, and accelerate the triggering of the trigger switch 22 of the circuit board 20 to shorten the pressing stroke.

[0096] Figure 7 is Figure 4 the cross-sectional view along the line 7-7, as shown in Figure 3 、 Figure 4 and Figure 7As shown, in this embodiment, at least one support member 12 (two support members 12 in this case, but this is not limiting) is further provided on the substrate 10, and each support member 12 abuts against the bottom of the first swing plate 71 and is located between the first outer side 711 and the first inner side 712. The support member 12 can be a plate member, a block, a rib, etc., so that the first swing plate 71 can swing with the support member 12 as a fulcrum when pressed. In addition, in this embodiment, each support member 12 is a C-shaped support member and has a side guide groove 121. The opposite sides of the first swing plate 71 are respectively received in the side guide grooves 121 of the two support members 12, so that the first swing plate 71 can be further limited by the support member 12 during the swinging process to avoid shaking or displacement. In addition, as Figure 3 shown, at least one support member 13 (two support members 13 in this case, but this is not limiting) can also be provided on the substrate 10 to abut against the bottom of the second swing plate 72, so that the second swing plate 72 can swing with the support member 13 as a fulcrum when pressed. Here, the support member 13 has the same or similar structure as the support member 12, so it will not be described in detail.

[0097] Figure 8 is Figure 4 a cross-sectional view along line 8-8. As Figure 3 、 Figure 4 and Figure 8 shown, in this embodiment, the trigger member 50 is located in the hollow hole 35. The receiving plate 30 has at least one abutting portion 301. Here, the receiving plate 30 has a plurality of abutting portions 301 and is respectively adjacent to the four corners of the hollow hole 35, and each abutting portion 301 is a notch provided at the edge of the hollow hole 35. The trigger member 50 has a plurality of abutting members 503 corresponding to the number and position of the abutting portions 301. Each of the abutting members 503 is a plate member extending from the periphery of the trigger member 50. The plurality of abutting members 503 of the trigger member 50 respectively abut against the plurality of abutting portions 301 of the receiving plate 30 to support the trigger member 50 and limit the horizontal displacement of the trigger member 50, so as to avoid the trigger member 50 from being displaced or falling downward during the actuation process. In addition, during the upward movement of the trigger member 50, if one side of the trigger member 50 is tilted, the abutting member 503 on the other side of the trigger member 50 will interfere with and press against the corresponding abutting portion 301, which can further accelerate the trigger member 50 to press against the reset member 40 to cause collapse to trigger the trigger switch 22.

[0098] However, the above embodiments are only examples. In some embodiments, each abutting portion 301 of the receiving plate 30 and each abutting member 503 of the triggering member 50 may be structures that can cooperate and abut against each other. For example, each abutting portion 301 of the receiving plate 30 may also be a plate member extending from the edge of the hollow hole 35, and each abutting member 503 of the triggering member 50 is a corresponding notch, or each abutting portion 301 of the receiving plate 30 may be a plate member extending from the edge of the hollow hole 35, and the triggering member 50 directly abuts on each abutting portion 301.

[0099] For another example Figure 3 , Figure 4 and Figure 8 As shown in, in this embodiment, the substrate 10 includes at least one supporting portion 101 corresponding to the hollow hole 35. Here, the substrate 10 has a plurality of supporting portions 101, and each supporting portion 101 is a folded plate formed by integrally bending the substrate 10 upward. The plurality of supporting portions 101 respectively abut against opposite sides of the bottom of the triggering member 50, so that the triggering member 50 is further supported by the substrate 10 to avoid situations such as displacement or dropping downward during the actuation process. In addition, during the upward movement of the triggering member 50, if one side of the triggering member 50 is tilted, the other side of the triggering member 50 will interfere and press against the corresponding supporting portion 101, which can further accelerate the triggering member 50 pressing against the reset member 40 to cause collapse to trigger the trigger switch 22.

[0100] For another example Figure 3 As Figure 4 shown, the triggering member 50 is further provided with at least one first limiting portion 501. Here, the triggering member 50 has two first limiting portions 501, and each first limiting portion 501 is a slot provided at the edge of the triggering member 50. The receiving plate 30 is provided with two second limiting portions 302 corresponding to the number and positions of the first limiting portions 501. Here, the second limiting portions 302 are protrusions and extend from the edge of the hole of the hollow hole 35, and the two second limiting portions 302 are respectively inserted into the two first limiting portions 501 and abut against each other to limit the horizontal displacement of the triggering member 50, so that the triggering member 50 is not easily offset or shaken during the lifting and lowering actuation process and is more stable.

[0101] However, the above embodiments are only examples. In some embodiments, the first limiting portion 501 of the triggering member 50 and the second limiting portion 302 of the receiving plate 30 may be structures that can cooperate and abut against each other. For example, the first limiting portion 501 and the second limiting portion 302 may both be protrusions and abut against each other, or the first limiting portion 501 may be a protrusion and the second limiting portion 302 may be a corresponding slot.

[0102] Figure 9 For Figure 4 a cross-sectional view along line 9-9, as Figure 3 shown in Figure 9As shown, in this embodiment, the trigger member 50 includes at least one stopper portion 502, and the stopper portion 502 abuts against the substrate 10 to limit the horizontal displacement of the trigger member 50. Here, the trigger member 50 includes a plurality of stopper portions 502, and each stopper portion 502 is a plate member integrally bent downward from the trigger member 50, and the plurality of stopper portions 502 are respectively located on opposite sides of the trigger member 50 and respectively abut against the outer sides of the support portions 101 of the substrate 10 to strengthen the limitation of the horizontal displacement of the trigger member 50.

[0103] As Figure 2 with Figure 3 As shown, in this embodiment, the receiving plate 30 further includes at least one limiting member 303. The limiting member 303 can be a slot for the corresponding limiting plate 14 of the substrate 10 to be inserted and abutted against each other, so as to limit the horizontal displacement of the receiving plate 30 through the substrate 10, making the receiving plate 30 less likely to shift or shake during the lifting operation and more stable.

[0104] However, the above embodiments are only examples. In some embodiments, it is only necessary that there is a structure that can cooperate and abut between the receiving plate 30 and the substrate 10. For example, the limiting member 303 of the receiving plate 30 can be a convex block to be correspondingly inserted into the slot of the substrate 10 to achieve the limitation of the horizontal displacement of the receiving plate 30, or the limiting member 303 of the receiving plate 30 can also be a convex block to be correspondingly abutted against the convex block on the substrate 10 to similarly limit the horizontal displacement of the receiving plate 30.

[0105] As Figure 3 with Figure 4 As shown, the receiving plate 30 is provided with a plurality of elastic arms 304, 305. After the pressure plate P is pressed, the elastic arm 304 elastically abuts against the first swing plate 71 and provides an elastic force toward the third side 33, and the elastic arm 305 elastically abuts against the second swing plate 72 and provides an elastic force toward the fourth side 34. After the pressure plate P is released, the first swing plate 71 and the second swing plate 72 can be accelerated to reset through the elastic arms 304, 305, and the first swing plate 71 and the second swing plate 72 can be more buffered by the elastic arms 304, 305 during the operation process to reduce vibration and noise.

[0106] Please refer to Figure 4 with Figure 5As shown, in this embodiment, the receiving plate 30 is provided with at least one limiting hook 39. The first outer side 711 of the first swing plate 71 is clamped between the limiting hook 39 and the main board 37 to prevent the first swing plate 71 from being displaced or shaken during actuation. In addition, by elastically abutting the elastic arm 304 against the first swing plate 71, it can further prevent the first outer side 711 of the first swing plate 71 from detaching from the limiting hook 39 to achieve the effect of strengthening the limit. In some embodiments, the receiving plate 30 may be provided with a plurality of limiting hooks 39, and some of the limiting hooks 39 are correspondingly clamped to the second outer side 721 of the second swing plate 72 to prevent the second swing plate 72 from being displaced or shaken during actuation, which is not shown here for simplicity.

[0107] As Figure 3 with Figure 4 As shown, in this embodiment, the touchpad device 1 further includes a third balance bar 63 and a fourth balance bar 64. The third balance bar 63 is disposed between the third side 33 of the receiving plate 30 and the first swing plate 71, and the fourth balance bar 64 is disposed between the fourth side 34 of the receiving plate 30 and the second swing plate 72. The third balance bar 63 includes a third rotating shaft 631 and two third side bars 632 respectively connected to both ends of the third rotating shaft 631. The third rotating shaft 631 is perpendicular to the first rotating shaft 611 and is pivotally provided on the receiving plate 30, and the two third side bars 632 are movably connected to the substrate 10. The fourth balance bar 64 includes a fourth rotating shaft 641 and two fourth side bars 642 respectively connected to both ends of the fourth rotating shaft 641. The fourth rotating shaft 641 is perpendicular to the first rotating shaft 611 and is pivotally provided on the receiving plate 30, and the two fourth side bars 642 are movably connected to the substrate 10. Thus, in the embodiment of the present invention, the rigidity of the corners and the periphery of the touchpad device 1 can be further improved through the third balance bar 63 and the fourth balance bar 64, so that when the pressure plate P is pressed, other components can be more quickly linked to improve the linkage effect.

[0108] Continuing from the above, as Figure 3As shown, in this embodiment, two third connecting members 104 are protruded from the substrate 10 and are arranged at intervals for connecting two third side rods 632, and two fourth connecting members 105 are protruded from the substrate 10 and are arranged at intervals for connecting two fourth side rods 642. Each of the third connecting members 104 and each of the fourth connecting members 105 are hook seats integrally bent and extended upward from the substrate 10 (herein, a U-shaped hook seat, but may also be a hook seat of other shapes such as an L-shaped or T-shaped hook seat). The end portions of the two third side rods 632 of the third balance rod 63 are respectively inserted into the two third connecting members 104, and the end portions of the two fourth side rods 642 of the fourth balance rod 64 are respectively inserted into the two fourth connecting members 105. Thus, when the touch plate P is pressed and descends toward the substrate 10, the third rotating shaft 631 and the fourth rotating shaft 641 can rotate relative to the receiving plate 30, and the end portions of each of the third side rods 632 can slide relative to the third connecting member 104, so that each of the third side rods 632 swings relative to the substrate 10, and the end portions of each of the fourth side rods 642 can slide relative to the fourth connecting member 105, so that each of the fourth side rods 642 swings relative to the substrate 10.

[0109] In summary, the touch panel device according to the embodiment of the present invention is provided with a first balance rod and a second balance rod respectively connected to the first side and the second side of the receiving plate, and a first swing plate and a second swing plate respectively adjacent to the third side and the fourth side of the receiving plate. When any part of the touch panel device (such as each corner or each edge of the touch plate) is pressed, other components can be quickly linked through the first balance rod, the second balance rod, the first swing plate and the second swing plate, so as to greatly reduce the dead travel when the touch plate is pressed. Furthermore, when the first swing plate and the second swing plate are pressed, they can drive the trigger member to move toward the trigger switch, and the mutual approach of the trigger switch and the trigger member can accelerate the pressing of the trigger switch to trigger the generation of a signal, further shortening the pressing stroke.
