[0035] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. Before the present invention is described in detail, it should be noted that the relative position terms used in the following description content, such as "front-back direction X", "left-right direction Y", "top-bottom direction Z", are based on the orientation shown in each figure and the normal use orientation. The front-back direction X is perpendicular to the left-right direction Y and the top-bottom direction Z.

[0036] Refer to Figure 1 , Figure 2 , Figure 3 , an embodiment of the global touch panel device 1 of the present invention is suitable for being installed at the bottom (not shown in the figure) of a keyboard housing of a notebook computer, and includes a base 10, a touch unit 20 located at the top end of the base 10 along the top-bottom direction Z, and a linkage unit 30 disposed between the base 10 and the touch unit 20. The touch unit 20 can be transformed relative to the base 10 between a raised position and a lowered position through the linkage unit 30.

[0037] Refer to Figures 2 to 5 , the base 10 is fixedly disposed on the keyboard housing and includes a trigger portion 11. The base 10 of this embodiment further includes a substrate 12 disposed along the left-right direction Y, and an intermediate plate 13 fixedly disposed on the top surface of the middle portion of the substrate 12. The trigger portion 11 is located on the intermediate plate 13. The length of the intermediate plate 13 along the left-right direction Y is less than the length of the substrate 12 along the left-right direction Y.

[0038] Refer to Figure 1 , Figure 3 , Figure 6 , the touch unit 20 includes a touch plate 21, a circuit board 22 connected to the bottom of the touch plate 21, and a trigger switch 23 disposed on a circuit board bottom surface 221 of the circuit board 22. The trigger switch 23 is located at the top end of the trigger portion 11 and can be pressed by the trigger portion 11 to trigger the generation of a signal. Regarding the trigger distance of the trigger switch 23, it can be finely adjusted by changing the thickness of the intermediate plate 13.

[0039] Refer to Figure 2 , Figure 3 , Figure 4 , the linkage unit 30 is symmetric in the front-back direction and the left-right direction with the trigger switch 23 and the trigger portion 11 as the reference, and includes an outer frame 31, an inner frame 32, a first connection group 33, a left side plate 34, a right side plate 35, a second connection group 36, and a limit group 37.

[0040] Refer toFigure 2 , Figure 3 , Figure 5 , the outer frame 31 defines an outer frame chamber 311, and has an outer frame top surface 312 and an outer frame bottom surface 313 in opposite directions. The outer frame top surface 312 is fixed to the edge of the bottom surface 221 of the circuit board.

[0041] The shape of the outer frame 31 corresponds to the shapes of the touch pressure plate 21 and the circuit board 22. In this embodiment, the touch pressure plate 21 and the circuit board 22 are rectangular, and the outer frame 31 correspondingly is a rectangular frame. The outer frame 31 can be a single rectangular frame or a rectangular frame composed of several plate bodies. In this embodiment, the outer frame 31 is a rectangular frame composed of an outer frame left plate 314, an outer frame right plate 315, an outer frame front plate 316 and an outer frame rear plate 317.

[0042] Refer to Figure 2 , Figure 4 , Figure 5 , the inner frame 32 is symmetric front and back and symmetric left and right with reference to the trigger switch 23 and the trigger portion 11. The inner frame 32 has flexibility, is located in the outer frame chamber 311, defines an inner frame chamber 321, and has an inner frame top surface 322 and an inner frame bottom surface 323 in opposite directions.

[0043] The shape of the inner frame 32 corresponds to the shape of the outer frame 31 as a rectangular frame. The inner frame 32 also has an inner frame left plate 324, an inner frame right plate 325, an inner frame front plate 326 and an inner frame rear plate 327.

[0044] The inner frame 32 can be a single rectangular frame or a rectangular frame composed of a front half-frame and a rear half-frame.

[0045] Refer to Figure 1 , Figure 6 , Figure 7 , the thickness t2 of the inner frame 32 is the distance between the inner frame top surface 322 and the inner frame bottom surface 323, the thickness t1 of the outer frame 31 is the distance between the outer frame top surface 312 and the outer frame bottom surface 313, and the thickness t2 of the inner frame 32 is less than the thickness t1 of the outer frame 31.

[0046] Refer to Figure 2 , Figure 4 , Figure 5, the first connecting group 33 includes several connecting blocks 331 fixed between the bottom surface 313 of the outer frame and the bottom surface 323 of the inner frame. In this embodiment, the first connecting group 33 includes four connecting blocks 331, and each connecting block 331 has a corner portion 332 fixed in the corner area of the bottom surface 313 of the outer frame, and a convex portion 333 protruding from the corner portion 332 and fixed to the bottom surface 323 of the inner frame. The positions of the connecting blocks 331 are preferably symmetrically arranged front and back and left and right with reference to the trigger switch 23 and the trigger portion 11.

[0047] Refer to Figure 2 , Figure 6 , Figure 7 , in the present invention, the first connecting group 33 is fixed between the bottom surface 313 of the outer frame and the bottom surface 323 of the inner frame, so that the outer frame 31 and the inner frame 32 are connected and fixed. Since the thickness t2 of the inner frame 32 is less than the thickness t1 of the outer frame 31, there is a gap 40 between the top surface 322 of the inner frame and the bottom surface 221 of the circuit board, so that the outer frame chamber 311 communicates with the inner frame chamber 321, and the bottom surface 221 of the circuit board cooperates with the outer frame chamber 311 and the inner frame chamber 321 to form a floating chamber 50 (floating chamber).

[0048] Refer to Figure 4 , Figure 5 , the left side plate 34 is flexible, extends along the front-rear direction X, and is fixed to the substrate 12 of the base 10, and is located in the inner frame chamber 321 near the left side plate 324 of the inner frame. The left side plate 34 has a middle portion 341 of the left side plate fixed to the substrate 12, a front portion 342 of the left side plate protruding from the middle portion 341 of the left side plate and extending towards the front plate 326 of the inner frame and protruding from the substrate 12, a rear portion 343 of the left side plate protruding from the middle portion 341 of the left side plate and extending towards the rear plate 327 of the inner frame and protruding from the substrate 12, and a left stop block 344 protruding from the middle portion 341 of the left side plate and extending towards the left side plate 324 of the inner frame and protruding from the substrate 12.

[0049] The right side plate 35 is flexible, extends along the front-rear direction X, and is fixed to the substrate 12, and is located in the inner frame chamber 321 near the right side plate 325 of the inner frame. The right side plate 35 has a middle portion 351 of the right side plate fixed to the substrate 12, a front portion 352 of the right side plate protruding from the middle portion 351 of the right side plate and extending towards the front plate 326 of the inner frame and protruding from the substrate 12, a rear portion 353 of the right side plate protruding from the middle portion 351 of the right side plate and extending towards the rear plate 327 of the inner frame and protruding from the substrate 12, and a right stop block 354 protruding from the middle portion 351 of the right side plate and extending towards the right side plate 325 of the inner frame and protruding from the substrate 12.

[0050] The left side plate 34 and the right side plate 35 are symmetric left and right with respect to the trigger portion 11, have the same thickness, and are abutted against the left and right sides of the middle plate 13.

[0051] Refer to Figure 2 、 Figure 4 、 Figure 5 and the second connecting group 36 has a left front connecting block 361 and a left rear connecting block 362 fixed between the bottom surface of the inner frame 323 and the bottom surface of the left side plate 34, and a right front connecting block 363 and a right rear connecting block 364 fixed between the bottom surface of the inner frame 323 and the bottom surface of the right side plate 35. Specifically, the left front connecting block 361 is fixed between the left part of the front plate 326 of the inner frame and the front part 342 of the left side plate, the left rear connecting block 362 is fixed between the left part of the rear plate 327 of the inner frame and the rear part 343 of the left side plate, the right front connecting block 363 is fixed between the right part of the front plate 326 of the inner frame and the front part 352 of the right side plate, and the right rear connecting block 364 is fixed between the right part of the rear plate 327 of the inner frame and the rear part 353 of the right side plate.

[0052] The limiting group 37 has a left limiting block 371 fixed to the bottom surface of the left plate 324 of the inner frame and located on the bottom side of the left stop block 344, and a right limiting block 372 fixed to the bottom surface of the right plate 325 of the inner frame and located on the bottom side of the right stop block 354.

[0053] Refer to Figure 1 、 Figure 4 、 Figure 6 When the full - area touchpad device 1 of the present invention is assembled, the touch unit 20 is located at the raised position relative to the base 10 through the linkage unit 30, and at the same time the trigger switch 23 is in the untriggered state.

[0054] When the user presses the touch plate 21, the touch unit 20 moves downward through the linkage unit 30 and is located at the lowered position relative to the base 10, so that the trigger switch 23 is pressed by the trigger portion 11, and then the trigger switch 23 changes from the untriggered state to the triggered state and generates a signal.

[0055] The operation and technical means of the full - area touchpad device 1 of the present invention will be described in detail below.

[0056] Refer to Figure 1 、 Figure 4 、 Figure 5When the right side of the touch-pressure plate 21 is pressed, the outer frame right plate 315, the right part of the outer frame front plate 316 and the right part of the outer frame rear plate 317 will be subjected to downward pressure and move toward the bottom end. Because the outer frame 31 and the inner frame 32 are connected by the first connecting group 33, the inner frame right plate 325, the right part of the inner frame front plate 326 and the right part of the inner frame rear plate 327 will be driven by the outer frame 31 to move toward the bottom end, causing the right part of the inner frame front plate 326 and the right part of the inner frame rear plate 327 to bend downward. At the same time, the right limit block 372 is driven by the inner frame right plate 325 to move toward the bottom end and disengage from the right stop block 354. At this time, the right front connecting block 363 is fixed between the right part of the inner frame front plate 326 and the front part 352 of the right side plate to form a right front fulcrum, and the right rear connecting block 364 is fixed between the right part of the inner frame rear plate 327 and the rear part 353 of the right side plate to form a right rear fulcrum. Theoretically, the left part of the inner frame front plate 326, the left part of the inner frame rear plate 327, and the inner frame left plate 324 will move toward the top, but because the left front connecting block 361 is fixed between the left part of the inner frame front plate 326 and the left side plate front part 342 to form a left front fixed point, and the left rear connecting block 362 is fixed between the left part of the inner frame rear plate 327 and the left side plate rear part 343 to form a left rear fixed point, the left part of the inner frame front plate 326, the left part of the inner frame rear plate 327, and the inner frame left plate 324 cannot move toward the top, and the left side of the touch plate 21 cannot move toward the top, thereby achieving the effect of limiting the swing stroke of the left and right sides of the touch unit 20 in the up and down direction. When the touch unit 20 moves to the descending position, the trigger switch 23 is pressed by the trigger part 11, and the trigger switch 23 can be changed from the untriggered state to the triggered state and generate a signal.

[0057] It is worth mentioning that because the left limit block 371 is fixed to the inner frame left plate 324 and is located on the bottom side of the left stop block 344, even if the left part of the inner frame front plate 326, the left part of the inner frame rear plate 327 and the inner frame left plate 324 have a tendency to move toward the top, they can still be blocked by the left stop block 344 through the left limit block 371, resulting in the effect that the left part of the inner frame front plate 326, the left part of the inner frame rear plate 327 and the inner frame left plate 324 cannot move toward the top.

[0058] When the pressing is released, the inner frame 32 returns to its original state due to its flexibility, and drives the touch unit 20 to move to the raised position, thereby changing the trigger switch 23 from the triggered state to the untriggered state.

[0059] Similarly, when pressing the left side of the touch plate 21, the touch control unit 20 will move to the lowered position by the same technical means, which will not be elaborated here.

[0060] It is easy to understand that since the structure of the linkage unit 30 is symmetric about the trigger switch 23 and the trigger portion 11, the touch feeling for triggering is the same when the user presses the left or right side of the touch plate 21.

[0061] Refer to Figure 1 、 Figure 4 、 Figure 8 When pressing the front side of the touch plate 21, the front frame plate 316 of the outer frame 31 will receive a downward pressure, and the front frame plate 326 of the inner frame 32, the front portions of the left inner frame plate 324 and the right inner frame plate 325 will also receive downward pressures. Since the middle portion 341 of the left side plate 34 is fixedly disposed on the substrate 12 to form a left fulcrum, and the middle portion 351 of the right side plate 35 is fixedly disposed on the substrate 12 to form a right fulcrum, the front portions of the left side plate 342 and the right side plate 352, and the front portions of the left inner frame plate 324 and the right inner frame plate 325 will be bent downward. Theoretically, the rear portions of the left inner frame plate 324, the right inner frame plate 325, and the rear frame plate 327 of the inner frame will move toward the top. However, since the left rear connecting block 362 is fixedly disposed between the left portion of the rear frame plate 327 of the inner frame and the rear portion 343 of the left side plate to form a left rear fixed point, and the right rear connecting block 364 is fixedly disposed between the right portion of the rear frame plate 327 of the inner frame and the rear portion 353 of the right side plate to form a right rear fixed point, the rear portions of the left inner frame plate 324, the right inner frame plate 325, and the rear frame plate 327 of the inner frame cannot move toward the top, and correspondingly, the rear side of the touch plate 21 cannot move toward the top either. Thus, the effect of restricting the swing stroke of the front and rear sides of the touch control unit 20 in the up and down direction is achieved. When the touch control unit 20 moves to the lowered position and the trigger switch 23 is pressed by the trigger portion 11, the trigger switch 23 can be changed from the untriggered state to the triggered state and generate a signal.

[0062] Similarly, when pressing the rear side of the touch plate 21, the touch control unit 20 will move to the lowered position by the same technical means, which will not be elaborated here.

[0063] It is easy to understand that since the linkage unit 30 is symmetric about the trigger portion 11 and the trigger switch 23, the touch feeling for triggering is the same when the user presses the front or rear side of the touch plate 21.

[0064] When pressing the middle area of the touch pressure plate 21, the outer frame 31 receives a downward pressure, driving the inner frame 32 to move toward the bottom end. The inner frame 32 drives the front part 342 and the rear part 343 of the left side plate, and the front part 352 and the rear part 353 of the right side plate to bend and deform downward, so that the touch control unit 20 moves smoothly to the descending position.

[0065] In summary, the full-area touch panel device 1 of the present invention has the following functions and advantages, so it can indeed achieve the purpose of the present invention.

[0066] First, the linkage unit 30 of the present invention is symmetrically arranged front and back and left and right with respect to the trigger portion 11 and the trigger switch 23. Pressing any part of the touch pressure plate 21 can produce a trigger effect, and the touch feelings of pressing the left side and the right side of the touch pressure plate 21 to produce a trigger effect are the same, and the touch feelings of pressing the front side and the rear side of the touch pressure plate 21 to produce a trigger effect are the same, which can improve the operation feeling.

[0067] Second, the present invention does not need to be provided with a stop structure. Through the structures of the left side plate 34, the right side plate 35, the inner frame 32 and the second connecting group 36, the swinging stroke and the moving stroke of the touch control unit 20 can be limited, and the use purpose and effect of full-area triggering can be achieved.

[0068] Third, the bottom surface 221 of the circuit board of the present invention cooperates with the outer frame chamber 311 and the inner frame chamber 321 to form the floating chamber 50. Therefore, when the user presses the touch pressure plate 21, there will be a cushion touch feeling, which can improve the operation feeling.

[0069] Fourth, through the floating chamber 50 of the present invention, the transmission efficiency of the downward pressure can be improved, and further, the pressing sensitivity can be improved and the moving smoothness of the touch control unit 20 can be improved.
