The inner surface 21 has a central area 215. Figure 2In the figure, a dotted line is used to indicate the boundary of the central area 215, but the dotted line is not an actual line of the touch panel 20, which is explained in advance.

The fourth balance bar 34 has a fourth inner end 341 and a fourth outer end 343 opposite to each other, and the fourth inner end 341 and the fourth outer end 343 are adjacent to the switch 22 and the fourth corner 214, respectively. That is to say, the first balance bar 31 , the second balance bar 32 , the third balance bar 33 and the fourth balance bar 34 surround the switch 22 and are arranged radially instead of being parallel to the side of the touch panel 20 .

[0101] like Figure 2 and Figure 3 As shown, the first balance bar 31 has a first shaft 315, the second balance bar 32 has a second shaft 325, the third balance bar 33 has a third shaft 335, and the fourth balance bar 34 has a fourth shaft 345, wherein the first shaft 315, the second shaft 325, the third shaft 335, and the fourth shaft 345 are respectively pivoted below the touch panel 20 and can rotate relative to the touch panel 20. For example, in this embodiment, the inner surface 21 of the touch panel 20 has an assembly plate 50, and the first shaft 315, the second shaft 325, the third shaft 335, and the fourth shaft 345 are respectively pivoted on the assembly plate 50. In some embodiments, the assembly plate 50 can be a hard plate made of metal or plastic, and the assembly plate 50 can be stacked and fixed on the inner surface 21 of the touch panel 20 by bonding, riveting, locking, or welding.

[0102] Figure 4 for Figure 2 A partial enlarged stereogram of Figure 5 for Figure 3 A partial enlarged stereogram of Figure 6 FIG. 1 is a top view of an embodiment of a touch panel device of the present invention, wherein Figure 6 The touch panel 20 is presented in a perspective manner so as to clearly show the arrangement of the balance component 30 covered by the touch panel 20. Figures 2 to 6As shown, the first balance bar 31 has a first swing bar 312a at a first inner end 311 adjacent to the switch 22, and a first swing bar 312b at a first outer end 313 adjacent to the first corner 211. The two first swing bars 312a and 312b are respectively connected to opposite ends of a first shaft 315, and each of the first swing bars 312a and 312b is substantially perpendicular to the first shaft 315. The second balance bar 32 has a second swing bar 322a at a second inner end 321 adjacent to the switch 22, and a second swing bar 322b at a second outer end 323 adjacent to the second corner 212. The two second swing bars 322a and 322b are respectively connected to opposite ends of a second shaft 325, and each of the second swing bars 322a and 322b is substantially perpendicular to the second shaft 325. The third balance bar 33 has a third swing bar 332a at a third inner end 331 adjacent to the switch 22, and a third swing bar 332b at a third outer end 333 adjacent to the third corner 213. The two third swing bars 332a and 332b are respectively connected to opposite ends of a third shaft 335, and each of the third swing bars 332a and 332b is substantially perpendicular to the third shaft 335. The fourth balance bar 34 has a fourth swing bar 342a at a fourth inner end 341 adjacent to the switch 22, and a fourth swing bar 342b at a fourth outer end 343 adjacent to the fourth corner 214. The two fourth swing bars 342a and 342b are respectively connected to opposite ends of a fourth shaft 345, and each of the fourth swing bars 342a and 342b is substantially perpendicular to the fourth shaft 345.

[0103] In some embodiments, the angle between each first swing arm 312a, 312b and the first axis 315, the angle between each second swing arm 322a, 322b and the second axis 325, the angle between each third swing arm 332a, 332b and the third axis 335, and the angle between each fourth swing arm 342a, 342b and the fourth axis 345 may also not be equal to 90 degrees (for example, the angle is 30 degrees, 45 degrees, 60 degrees, 120 degrees, 135 degrees or 150 degrees).

[0104] like Figures 2 to 6As shown, the substrate 10 has two first assembling components 11, two second assembling components 12, two third assembling components 13 and two fourth assembling components 14, wherein the two first assembling components 11 are spaced apart from each other and are respectively assembled with two first swinging bars 312a, 312b of the first balance bar 31. For example, each first assembling component 11 can be a plate (such as a U-shaped, L-shaped, or T-shaped plate) that is bent and extended upward from the substrate 10 as a whole. The two first swinging bars 312a, 312b of the first balance bar 31 are respectively movably assembled to the two first assembling components 11. When the touch panel 20 is pressed and descends toward the substrate 10, the first shaft 315 of the first balance bar 31 can rotate relative to the touch panel 20, and the two first swinging bars 312a, 312b can swing relative to the substrate 10, so that the ends of the two first swinging bars 312a, 312b can be tilted toward the touch panel 20. The structures of the second assembling components 12, the third assembling components 13 and the fourth assembling components 14 may be the same as the first assembling components 11. In the present embodiment, the two second assembling components 12 are spaced apart from each other and are respectively used to movably assemble the two second swing arms 322a, 322b of the second balance bar 32. The two third assembling components 13 are spaced apart from each other and are respectively used to movably assemble the two third swing arms 332a, 332b of the third balance bar 33. The two fourth assembling components 14 are spaced apart from each other and are respectively used to movably assemble the two fourth swing arms 342a, 342b of the fourth balance bar 34. The actuation mode of the second balance bar 32, the third balance bar 33 and the fourth balance bar 34 when the touch panel 20 is pressed may be the same as the first balance bar 31, which will not be repeated here.

[0105] As above, Figure 3 and Figure 5As shown, in this embodiment, each first assembly member 11 includes two vertical plates 111 and a horizontal plate 112, the two vertical plates 111 are spaced apart from each other and are integrally connected to the base plate 10, and each vertical plate 111 is perpendicular to the base plate 10. The horizontal plate 112 of each first assembly member 11 is perpendicular to each vertical plate 111 and is integrally connected between the two vertical plates 111, so that each first assembly member 11 is a semi-closed U-shaped plate, each first swing rod 312a, 312b of the first balance bar 31 is located between the two vertical plates 111 and the horizontal plate 112, and each first swing rod 312a, 312b is against the bottom surface of the horizontal plate 112. Thus, when the touch panel 20 is pressed and descends toward the substrate 10, each first swing rod 312a, 312b can swing relative to the substrate 10 with the portion against the horizontal plate 112 as a fulcrum, so that the end of each first swing rod 312a, 312b tilts toward the touch panel 20. In addition, by each first assembly member 11 being a semi-enclosed U-shaped plate, the first assembly member 11 as a whole can have a better structural strength, and the first assembly member 11 can be prevented from being deformed when subjected to force. In some embodiments, the structure of each second assembly member 12, each third assembly member 13, and each fourth assembly member 14 can be the same as that of each first assembly member 11 and be a semi-enclosed U-shaped plate, and will not be repeated here.

[0106] Thus, through the arrangement of the above-mentioned balancing element 30, when any part of the touch panel 20 (such as each corner or each edge of the touch panel 20) is pressed, the pressing force can be directly and quickly transmitted to the switch 22 in the central area 215 through the balancing element 30. Figure 2 , Figure 3 and Figure 6 As shown, when the first corner 211 of the touch panel 20 is pressed, since the two ends of the first balance bar 31 are respectively adjacent to the first corner 211 and the switch 22, the pressing force can be directly transmitted to the switch 22 along the extension direction of the first balance bar 31. Similarly, when the second corner 212, the third corner 213 or the fourth corner 214 of the touch panel 20 is pressed, the pressing force can also be directly transmitted to the switch 22 via the second balance bar 32, the third balance bar 33 or the fourth balance bar 34, respectively, so as to improve the transmission efficiency of the pressing force, and also avoid problems such as shaking, bending or excessive idle travel when the corners or edges of the touch panel 20 are pressed.

[0107] Figure 7 for Figure 6 The cross-sectional view along line segment 7-7, Figure 8 for Figure 7 The pressing diagram is as follows: Figures 2 to 7As shown, the trigger member 40 is located between the central area 215 of the touch panel 20 and the substrate 10. The trigger member 40 has a top 41 and a bottom 45. The bottom 45 is supported by the ends of the first swing rod 312a, the second swing rod 322a, the third swing rod 332a and the fourth swing rod 342a adjacent to the switch 22. The top 41 of the trigger member 40 contacts the switch 22 to keep the touch panel 20 at a height position. In addition, in this embodiment, the assembly plate 50 has a hollow hole 51. The position of the trigger member 40 corresponds to the position of the hollow hole 51 to avoid the trigger member 40 and the switch 22 being blocked by the assembly plate 50. In this regard, please also refer to Figure 7 and Figure 8 As shown, when the touch panel 20 is pressed and descends toward the substrate 10, the ends of the first swing rod 312a, the second swing rod 322a, the third swing rod 332a and the fourth swing rod 342a can swing relative to the substrate 10 to apply a force toward the touch panel 20 to the trigger member 40, so that the trigger member 40 is lifted toward the switch 22 and presses the switch 22 to collapse, thereby accelerating the triggering of the switch 22 and shortening the pressing stroke, so as to provide the user with a better operating feel.

[0108] In some embodiments, the bottom 45 of the trigger member 40 may be in point contact or surface contact with the ends of the first swing rod 312a, the second swing rod 322a, the third swing rod 332a, and the fourth swing rod 342a. Figure 7 and Figure 8 As shown, in this embodiment, the bottom 45 of the trigger member 40 has a plurality of inclined surfaces 451. When the touch panel 20 is not pressed (eg, Figure 7 As shown in FIG. 1 , the plurality of inclined surfaces 451 are respectively the same as the inclination angles of the first swing bar 312a, the second swing bar 322a, the third swing bar 332a and the fourth swing bar 342a, and the plurality of inclined surfaces 451 are respectively supported by the inclined surfaces of the ends of the first swing bar 312a, the second swing bar 322a, the third swing bar 332a and the fourth swing bar 342a, so that the triggering member 40 and the first swing bar 312a, the second swing bar 322a, the third swing bar 332a and the fourth swing bar 342a form a surface contact instead of a point contact. Thus, when the touch panel 20 is pressed and the first swing bar 312a, the second swing bar 322a, the third swing bar 332a and the fourth swing bar 342a swing relative to the substrate 10, the force can be more effectively transmitted to the triggering member 40 through the above-mentioned surface contact method, so that the triggering member 40 is lifted toward the touch panel 20. In some embodiments, the bottom 45 of the trigger member 40 may also bear against the ends of the first swing bar 312a, the second swing bar 322a, the third swing bar 332a and the fourth swing bar 342a through sides or corners (such as arc edges or rounded corners) to form point contacts.

[0109] In some embodiments, the trigger member 40 may be composed of at least one plate. Figures 2 to 6As shown, in this embodiment, the trigger member 40 includes a first plate 42 and a second plate 43 stacked and fixed to each other, wherein the first plate 42 contacts the switch 22, and the second plate 43 rests on the ends of the first swing rod 312a, the second swing rod 322a, the third swing rod 332a, and the fourth swing rod 342a. For example, the first plate 42 and the second plate 43 can be fixed to each other by adhesion, buckle, or locking. However, the above embodiment is only an example, and the trigger member 40 may also only include the above first plate 42 or the second plate 43.
