Description

Touch control device

Technical Field

The present invention relates to a touch device, and more particularly, to a pressing type touch device.

Background

The touch pad is a common input device in current electronic devices, and has functions of cursor dragging, clicking and zooming. In addition, if the touch pad is a pressing type touch pad, the touch pad also has the functions of left and right keys similar to a mouse. In order to make the user have clear pressing action and touch feeling, the function of left and right keys can only be generated at specific positions (such as left lower and right lower) of the touch pad.

However, when the user inputs an input using the keyboard, the position of the thumb is not exactly located at the specific position of the touch pad, and therefore, the user must move the position of the thumb to a position below the touch pad to perform the pressing operation, which is inconvenient. In addition, the conventional pressing type touch pad cannot change the setting to change the pressing touch feeling of the user (i.e. the touch feeling is not adjustable), so that the user cannot adjust the pressing feedback force by himself/herself, for example, the feedback force needs to be increased for playing or reduced for reducing noise.

According to an aspect of the present invention, a pressing type touch device is provided, which includes a touch pad, a pressing switch element and a supporting structure. The touch pad has an upper surface and a first side and a second side opposite to the upper surface. The press switch element is arranged below the touch pad and adjacent to the first side or the second side, the support structure is used for supporting the touch pad, one side of the support structure is provided with a plurality of limiting seats, and when the touch pad is pressed, the press switch element presses the support structure by taking the limiting seats as fulcrums.

Detailed Description

The following embodiments are provided for illustrative purposes only and are not intended to limit the scope of the present invention.

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted.

Example one

Referring to fig. 1A and 1B, fig. 1A and 1B respectively illustrate an external view and an exploded view of internal components of a push type touch device 101 according to an embodiment of the invention. The push type touch device 101 can be applied to a notebook computer or other types of electronic devices, and a user can use the push type touch device 101 to replace a mouse to execute cursor movement and generate a left-right key pressing function. For example, the user may press a lower left or lower right position of the touch pad 110 to perform the left or right key function of the mouse, or the user may press an upper left or upper right position of the touch pad 110 to perform the left or right key function of the mouse, and thus, the user is not limited to pressing only at a specific position, and the user may perform the left or right key function of the mouse without moving the position of the thumb to a position below the touch pad 110.

As shown in fig. 1A and 1B, the pressing type touch device 101 includes a touch pad 110, a supporting structure 120 and a pressing switch element 130. The touch pad 110 has an upper surface 111 and a first side 112 and a second side 113 opposite to each other. The upper surface 111 is a touch surface, the first side 112 is an upper side, and the second side 113 is a lower side. For example, the touch pad 110 uses the first side 112 as a limit side and the second side 113 as a pressing side, so that the touch pad 110 can swing up and down relative to the first side 112 with the first side 112 as a fulcrum and the second side 113 as a fulcrum. In another embodiment, for example, the touch pad 110 uses the second side 113 as a limiting side, and uses the first side 112 as a pressing side, so that the touch pad 110 uses the second side 113 as a fulcrum, and the first side 112 can swing up and down relative to the second side 113. The push switch element 130 may be disposed under the touch pad 110 and adjacent to the first side 112 or the second side 113, corresponding to different embodiments. The following description is given by taking the push switch element 130 disposed adjacent to the second side 113 as an example.

The push switch element 130 is, for example, a metal dome switch, and is disposed on the lower side of a circuit board 131. In another embodiment, not shown, the push switch element 130 is located on the upper side of the circuit board 131. The metal elastic piece switch is provided with an arc-shaped elastic piece which is pressed to contact a switch to conduct the switch so as to generate a pressing signal. Therefore, the controller of the touch pad 110 can receive the pressing signal and the position signal of the finger pressing the touch pad 110, and the user can feel a pressing resistance (i.e. a touch) when pressing the arc-shaped elastic sheet, and when the user releases the pressing, the user can clearly feel the resilience of the push switch element 130 through the resilience of the arc-shaped elastic sheet. Meanwhile, the controller may determine a function to be triggered by the user according to a position where the touch pad 110 is pressed by the finger, so as to transmit a left key or a right key signal.

Referring to fig. 1B, the push switch element 130 is disposed below the touch pad 110 and between the touch pad 110 and the supporting structure 120, and the supporting structure 120 is used for supporting the touch pad 110 and making the touch pad 110 have a pushing function. In addition, the supporting structure 120 has a plurality of position limiting seats 122 disposed adjacent to the first side 112. In another embodiment, not shown, the position-limiting seat 122 is disposed adjacent to the second side 113. When the touch pad 110 is pressed, the push switch element 130 can be pressed on the supporting structure 120 with the stopper 122 as a fulcrum.

In the present embodiment, the supporting structure 120 includes a supporting frame 121, wherein the supporting frame 121 further includes a lower frame 1211 and an upper frame 1212, the lower frame 1211 has a plurality of blocking pieces 1221 bent upward from a groove, the upper frame 1212 has a plurality of blocking pieces 1222 bent downward from a groove, and each blocking piece 1221 is opposite to a corresponding blocking piece 1222 to form the limiting seat 122. When the touch pad 110 is pressed, the two

stoppers

1221 and 1222 are separated, and when the pressing of the touch pad 110 is released, the two

stoppers

1221 and 1222 are contacted to interfere with each other. Through the relative position relationship between the two blocking pieces, the other side of the touch pad 110 can press the push switch element 130 with the limiting seat 122 as a fulcrum to generate a push signal.

In addition, in order to make the touch pad 110 move up and down with even force, the supporting structure 120 further includes a cantilever supporting rod 123 and a connecting rod 126. The area of the supporting frame 121 is substantially equal to the area of the touch pad 110. The cantilever-type supporting rod 123 is disposed on an opposite side of the supporting frame 121 (i.e., a side away from the position-limiting seat 122) corresponding to the position-limiting seat 122, and a center of the cantilever-type supporting rod 123 presses the switch element 130. In the present embodiment, the center of the cantilever support rod 123 has two cantilevers 124 and a contact pad 125, for example, and the contact pad 125 is connected between the two cantilevers 124. The two cantilevers 124 can make the upper and lower corresponding touch pads 125 and the push switch device 130 uniformly stressed, thereby avoiding the failure problem caused by poor contact between the touch pads 125 and the push switch device 130 when the touch pad 110 is not uniformly stressed and is tilted. In addition, a pad 128 corresponding to the push switch element 130 can be further disposed on the contact pad 125 for preloading, and the thickness of the pad 128 can be different, so as to adjust the force and feel of the push trigger according to the different thickness. The material of the pad 128 is, for example, mylar, but is not limited thereto.

In addition, the connecting rod 126 is, for example, a long bar, which extends along one side (e.g., the long side) of the supporting frame 121 and is pivotally installed on the cantilever supporting rod 123. The two ends 127 of the connecting rod 126 are bent to abut against the upper side of the short side of the supporting frame 121 for balancing the stress on the two sides of the touch pad 110, so as to avoid the inclination of the touch pad 110 caused by uneven stress.

As can be seen from the above description, the present embodiment generates the pressing signal of the local area by pressing the pressing switch element 130 located on a single side (the first side 112 or the second side 113), and the thickness of the adjusting pad 128 can adjust the force and feel of the pressing trigger of the pressing switch element 130, so as to meet the design requirement of operation.

Example two

Referring to fig. 2A and 2B, fig. 2A and 2B are respectively an exploded view of an internal element and a schematic view of an element driving configuration of a push type touch device 102 according to another embodiment of the invention. The push-type touch device 102 of the present embodiment and the above embodiments generate the push signal of the local area by pressing the push switch element located on a single side (the first side 112 or the second side 113), and the difference is that: in the embodiment, the resilient force of the push switch element 130' is adjusted in an electrically controlled manner, so that a user can change the setting according to the requirement, for example, the feedback force needs to be increased for playing or decreased for reducing noise, so as to meet the design requirement in operation.

Referring to fig. 2B, the push type touch device 102 of the present embodiment includes a driving element 140, and the driving element 140 is electrically connected between the touch pad 110 and the push switch element 130', for example. When the touch pad 110 and the push switch device 130 ' are pressed to generate the push signal P, the driving device 140 outputs an electrical signal E to the push switch device 130 ', and the push switch device 130 ' converts the electrical signal E into a forced feedback signal to generate a resilient force F. In one embodiment, the push switch element 130' is, for example, a piezoelectric switch or other type of switch (e.g., an electromagnetic switch), and the piezoelectric switch has a flexible elastic sheet or composite material, which can adjust the resilience according to the strength of the electrical signal, so as to provide different push feelings for the user. The driving element 140 may be an integrated circuit having an input end, an output end, and a variable voltage setting module (not shown), and the elastic force F is changed by adjusting the electrical signal E of the output end through the pressing signal P of the input end and the variable voltage setting module.

EXAMPLE III

Referring to fig. 3, fig. 3 is an exploded view of internal components of a push type touch device 103 according to another embodiment of the invention. The pressing type touch device 103 of the present embodiment is substantially the same as the two embodiments, except that: in the present embodiment, the pressing signals of the full-area pressing are generated by at least two pressing switch devices 130 disposed on two sides of the circuit board 131 (adjacent to the first side 112 and the second side 113 of the touch pad 110), and a predetermined pressing feeling (or different pressing feelings) can be generated by the resilience of the pressing switch devices 130, so as to meet the design requirement of the operation. The push switch element 130 is, for example, a metal dome switch or other type of switch element (e.g., a piezoelectric switch or an electromagnetic switch).

The supporting structure 120' of the present embodiment includes a supporting frame 121, two cantilever-type supporting rods 123 and two connecting rods 126. Two limiting seats 122' are correspondingly disposed on two sides of a central portion of the supporting frame 121, and the structure thereof is similar to the limiting seat 122 described above, and will not be described herein again. Through the position limitation of the position limiting seat 122 ', the opposite sides (e.g., the long sides) of the touch pad 110 swing up and down with the position limiting seat 122' as a fulcrum. That is, the difference from the above two embodiments is: the position-limiting seats 122 'are located on two sides of a central portion between the first side 112 and the second side 113 of the touch pad 110, and when the touch pad 110 is pressed, the at least two push switch devices 130 are pressed on the support structure 120 with the central position-limiting seats 122' as a fulcrum.

In addition, the center of the two cantilever-type support rods 123 respectively press the two push switch elements 130, and the two connecting rods 126 are respectively pivoted to the two cantilever-type support rods 123 for balancing the stress on the two sides of the support frame 121, thereby preventing the two sides of the touch pad 110 from being stressed unevenly and inclined.

Example four

Referring to fig. 4, fig. 4 is an exploded view of internal components of a push type touch device 104 according to another embodiment of the invention. The pressing type touch device 104 of the present embodiment is substantially the same as the third embodiment, except that: the push switch element 130 'may be disposed on both sides of the circuit board 131, or may be disposed on the center of the circuit board 131, so that when the user presses the center of the touch pad 110, the push switch element 130' still generates a push signal, and is not limited to be disposed on only two opposite sides of the circuit board 131.

In addition, in the present embodiment, the resilience of the push switch element 130' is adjusted through an electrical control manner, so that the user can change the setting as required, please refer to fig. 2B. In one embodiment, the driving element 140 outputs an electrical signal E to the push switch element 130 ', and the push switch element 130' converts the electrical signal E into a forced feedback signal to generate a resilient force path F. The push switch element 130' is, for example, a piezoelectric switch or other types of switches (e.g., electromagnetic switches), and the piezoelectric switch has a flexible elastic sheet or composite material, which can adjust the resilience according to the strength of the electrical signal, so as to provide different push feelings for the user.

EXAMPLE five

Referring to fig. 5, fig. 5 is an exploded view of internal components of a push type touch device 105 according to another embodiment of the invention. The push type touch device 105 of the present embodiment has substantially the same component configuration as that of the third and fourth embodiments, and the difference is that: the push switch element 130 is disposed only in the center of the circuit board 131. Although the push switch device 130 is not disposed on two sides of the circuit board 131, the two cantilever-type support rods 123 and the two connecting rods 126 are disposed on two opposite sides of the supporting structure 120 ″ respectively, so that the two opposite sides of the touch pad 110 can move up and down with even force, and the push switch device 130 disposed in the center of the circuit board 131 can still generate a push signal to realize a full-area push function.

In addition, in the embodiment, the cantilever support rod 123 may be additionally disposed at the center of the support frame 121 in addition to being disposed at the two opposite sides of the support frame 121, as shown in fig. 5, the support structure 120 ″ includes a cantilever bracket 123 'similar to the structure of the cantilever support rod 123, for example, the center of the cantilever bracket 123' has two cantilevers 124 and a contact pad 125, and the contact pad 125 is connected between the two cantilevers 124. The two cantilevers 124 can make the upper and lower corresponding touch pads 125 and the push switch device 130 uniformly stressed, thereby avoiding the failure problem caused by poor contact between the touch pads 125 and the push switch device 130 when the touch pad 110 is not uniformly stressed and is tilted. In addition, the contact pad 125 may further be provided with a pad corresponding to the push switch element 130 for pre-loading, and the pad may be provided with different thicknesses, so as to adjust the force and feel of the push trigger according to the different thicknesses.

EXAMPLE six

Referring to fig. 6, fig. 6 is an exploded view of internal components of a push type touch device 106 according to another embodiment of the invention. The push type touch device 106 of the present embodiment has substantially the same configuration as that of the fifth embodiment, except that: in this embodiment, the resilient force of the push switch element 130' is adjusted through an electrical control manner, so that a user can change the setting as needed, as shown in fig. 2B, which is not described again. The push switch element 130' is, for example, a piezoelectric switch or other type of switch (e.g., an electromagnetic switch), and can adjust the resilient force according to the strength of the electrical signal, so that the user can have different push feelings.

Since the present embodiment has only a single push switch element 130 ', the cost of the element can be saved compared to providing a plurality of push switch elements 130'.

In addition, when the push switch element 130' is only disposed in the center of the circuit board 131, the

push touch devices

101 and 102 with single-side push can be applied, as shown in fig. 1B and 2A, but not limited to the application of the push touch device with double-side push.

The pressing type touch device of the above embodiment of the invention can adjust the resilience according to the requirement, so that the user has different pressing feelings, and can realize the function of pressing the touch panel locally or completely. For example, the push switch element may be disposed at two sides, the center, or both sides of the circuit board as required, and the user can press the left lower, right lower, left upper, right upper, center, or other positions of the touch pad to implement a local or full-area pressing function through a single-side pressing type touch device or a double-side pressing type touch device.

In summary, although the present invention has been described with reference to the above embodiments, the present invention is not limited thereto.
