touch device

Technical field

The present invention relates to a touch device, and in particular to a push-type touch device.

Background technique

The touchpad is a common input device in current electronic devices and has cursor dragging, clicking and zooming functions. In addition, if it is a push-type touch pad, it also has left and right button functions similar to that of a mouse. In order to allow users to have a clear pressing action and touch feeling, currently only the left and right key functions can be generated at specific positions of the touchpad (such as the lower left and lower right).

However, when the user uses the keyboard to input, the position of the thumb is not exactly at a specific position of the touch pad. Therefore, the user must move the thumb position to the bottom of the touch pad to perform pressing, which causes inconvenience. In addition, the traditional push-type touchpad cannot change the settings to change the user's pressing feel (that is, the touch cannot be adjusted). Therefore, the user cannot adjust the pressing feedback force by himself, such as increasing the feedback force for gaming needs or for noise reduction. Feedback needs to be reduced.

Embodiment 1

Please refer to FIGS. 1A and 1B , which respectively illustrate an appearance view and an exploded view of internal components of a push-type touch device 101 according to an embodiment of the present invention. The push-type touch device 101 can be applied to a notebook computer or other types of electronic devices. The user can use the push-type touch device 101 to replace the mouse to perform cursor movement and generate left and right key press functions. For example, the user can press the lower left or lower right position of the touch pad 110 to execute the left and right button functions of the mouse, or the user can press the upper left or upper right position of the touch pad 110 to execute the left and right button functions of the mouse. Therefore, there is no limitation. It can only be pressed at a specific position, so that the user can perform the left and right button functions of the mouse without moving the thumb position below the touch pad 110 .

As shown in FIGS. 1A and 1B , the push touch device 101 includes a touch panel 110 , a support structure 120 and a push switch element 130 . The touch panel 110 has an upper surface 111 and an opposite first side 112 and a second side 113 . The upper surface 111 is a touch surface, the first side 112 is, for example, the upper side, and the second side 113 is, for example, the lower side. For example, the touch panel 110 uses the first side 112 as the limiting side and the second side 113 as the pressing side, so that the touch panel 110 uses the first side 112 as the fulcrum, and the second side 113 can swing up and down relative to the first side 112 . In another embodiment, the touch panel 110 uses the second side 113 as the limiting side and the first side 112 as the pressing side, so that the touch panel 110 uses the second side 113 as the fulcrum, and the first side 112 is relative to The second side 113 can swing up and down. According to different embodiments, the push switch element 130 may be disposed below the touch panel 110 and adjacent to the first side 112 or the second side 113 . The following description takes 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 spring switch, which is disposed on the underside of a circuit board 131 . In another not-shown embodiment, the push switch element 130 is located on the upper side of the circuit board 131, for example. The metal spring piece switch has an arc-shaped spring piece, and the arc-shaped spring piece is pressed to contact a switch to conduct the switch to generate a pressing signal. Therefore, the controller of the touch panel 110 can receive the press signal and the position signal of the finger pressing the touch panel 110, and when the user presses the arc-shaped spring piece, he or she feels a pressing resistance (i.e., touch), and when the user presses and releases the , through the rebound force of the arc-shaped elastic piece, the user can clearly feel the rebound force of pressing the switch element 130 . At the same time, the controller can determine the function that the user wants to trigger based on the position of the finger pressing the touch panel 110, so as to send a left or right button signal.

Referring to Figure 1B, the push switch element 130 is disposed below the touch panel 110 and between the touch panel 110 and the support structure 120.

When the touch panel 110 is pressed, the two blocking pieces 1221 and 1222 separate. When the touch panel 110 is released, the two blocking pieces 1221 and 1222 contact and interfere with each other. Through the relative positional relationship between the two blocking pieces, the other side of the touch panel 110 can press the pressing switch element 130 with the limiting seat 122 as a fulcrum to generate a pressing signal.

In addition, in order to enable the touch panel 110 to move up and down under even force, the support structure 120 also includes a cantilever support rod 123 and a connecting rod 126 . The area of the support frame 121 is substantially equivalent to the area of the touch panel 110 . The cantilever support rod 123 is disposed on an opposite side of the support frame 121 corresponding to the limit seat 122 (that is, the side away from the limit seat 122), and the center of the cantilever support rod 123 presses the switch element 130. In this embodiment, the center of the cantilevered support rod 123 has, for example, two cantilever arms 124 and a contact pad 125 . The contact pad 125 is connected between the two cantilever arms 124 . The two cantilevers 124 can make the upper and lower corresponding contact pads 125 and push switch elements 130 receive even force, thereby avoiding the problem of poor contact between the contact pad 125 and the push switch element 130 when the touch panel 110 is tilted due to uneven force. In addition, the contact pad 125 can be further provided with a pad 128 corresponding to the push switch element 130 for preloading. The pad 128 can be set to different thicknesses, and the force and feel of the push trigger can be adjusted according to the thickness of the pad 128 . The material of the gasket 128 is, for example, Mylar sheet, but is not limited thereto.

In addition, the connecting rod 126 is, for example, a long strip, which extends along one side (eg, the long side) of the support frame 121 and is pivotally mounted on the cantilevered support rod 123 . The two ends 127 of the connecting rod 126 are bent and abutted above the short sides of the support frame 121 to balance the forces on both sides of the touch panel 110 and prevent the touch panel 110 from tilting due to uneven forces.

As can be seen from the above description, this embodiment generates a press signal in a local area by pressing the press switch element 130 located on a single side (the first side 112 or the second side 113 ), and the thickness of the adjustment gasket 128 can be adjusted. The force and feel of pressing and triggering the switch element 130 are determined to meet the operational design requirements.
