Description
Technical Field
The present invention relates to the field of input devices, and in particular, to an input device with a touch function.
Background
With the development of technology, the electronic devices are greatly developed to bring convenience to human life, and therefore it is an important issue how to make the operations of the electronic devices more humanized. For example, the common electronic devices in daily life are notebook computers, mobile phones, satellite navigation devices, and the like, and the storage capacities and the operation performance of the processors of the electronic devices are greatly improved, so that the functions of the electronic devices become increasingly powerful and complex. In order to operate a plurality of electronic devices efficiently, manufacturers of electronic devices use touch pads as input devices to operate the plurality of electronic devices.
Please refer to fig. 1, which is a schematic structural diagram of a conventional notebook computer and a touch pad module thereof. The touch pad module 1 is disposed in the housing 21 of the notebook computer 2 and at least partially exposed to allow a user to touch the touch pad module 1 to operate the notebook computer 2, for example, the user can touch the touch pad module 1 with fingers and slide on the touch pad module 1 to move a cursor 23 on a screen 22, or can press the touch pad module 1 to allow the notebook computer 2 to perform a specific function, so that the touch pad module 1 can replace the function of a mouse, and the user does not need to carry or install the mouse additionally, which is inconvenient.
Referring to fig. 2 to 4 synchronously, fig. 2 is a conceptual diagram of the touch pad module shown in fig. 1 when the touch pad module is not pressed, fig. 3 is a conceptual diagram of the touch pad module shown in fig. 2 after the touch pad module is pressed, and fig. 4 is a conceptual diagram of a partial structure cross section of the circuit board and the switch of the touch pad module shown in fig. 1. The housing 21 of the notebook computer 2 has an inwardly recessed frame 24, and opposite sides in the frame 24 are respectively provided with a supporting structure 241 and a triggering portion 242 extending into the frame 24, and the first end 11 of the touch pad module 1 is connected to the supporting structure 241, so that the second end 12 of the touch pad module 1 can swing relative to the triggering portion 242 with the supporting structure 241 as a fulcrum.
In addition, the touch panel module 1 includes a switch 13 and a circuit board 14, the switch 13 is located below the second end 12 of the touch panel module 1 and corresponds to the triggering portion 242, and a metal dome elastic body (metal dome)131 is disposed in the switch 13, and the circuit board 14 has a first conductive portion 141 and a second conductive portion 142 corresponding to the metal dome elastic body 131, and a distance is provided between the first conductive portion 141 and the second conductive portion 142, wherein when the touch panel module 1 is not pressed, the metal dome elastic body 131 is not deformed, and at this time, the metal dome elastic body 131 only contacts the first conductive portion 141 but not the second conductive portion 142, as shown in fig. 4.
Furthermore, when the user touches the touch pad module 1, the second end 12 of the touch pad module 1 swings downward relative to the triggering portion 242 with the supporting structure 241 as a fulcrum until the switch 13 of the touch pad module 1 abuts against the triggering portion 242 of the frame 24 to deform the metal dome elastic body 131, and at this time, the metal dome elastic body 131 contacts the second conductive portion 142 in addition to the first conductive portion 141, so that electrical conduction is formed between the first conductive portion 141 and the second conductive portion 142, and thus, the switch 13 is triggered to output a switch signal to the notebook computer 2, thereby enabling the notebook computer 2 to perform a corresponding function. When the user no longer touches the touch pad module 1, the second end 12 of the touch pad module 1 swings upward relative to the trigger 242 according to the elastic force of the metal dome elastic body 131 and/or the elastic force of the supporting structure 241, so that the shape of the metal dome elastic body 131 is restored as shown in fig. 4, and the touch pad module 1 is restored.
However, the conventional touch pad module 1 has a disadvantage that unpleasant noises are generated when the user touches and presses the touch pad module 1, and a plurality of noises are generated by sounds generated when the switch 13 hits the trigger part 242 and sounds generated when the metal dome elastic body 131 is deformed and hits the second conductive part 142. Therefore, a conventional touch pad module in which a rubber (not shown) is disposed on the trigger 242 to buffer the switch 13 from directly striking the trigger 242, and a touch pad module in which the switch 13 is covered by a rubber cover (not shown) to block the transmission of the internal striking sound to the outside are also proposed. However, the trigger 242 has a limited noise reduction effect and thus has room for improvement, regardless of whether a rubber member is provided or the switch 13 is covered with a rubber cover.

Please refer to fig. 11, which is a conceptual diagram of the touch pad module shown in fig. 6 when being pressed. When the upper cover plate 31 of the touch pad module 3 is pressed, the first end 34 of the touch pad module 3 swings downward relative to the trigger part 46 with the supporting structure 47 as a fulcrum until the surface-mounted switch 33 abuts against the trigger part 46 to deform the metal dome elastic body 332 in the surface-mounted switch 33, and during the deformation of the metal dome elastic body 332, a portion of the metal dome elastic body 332 corresponding to the base conductive part 3311 contacts the base conductive part 3311, and a portion of the metal dome elastic body 332 corresponding to the elastic conductive part 333 contacts the elastic conductive part 333, so that an electrical conduction is formed between the base conductive part 3311 and the elastic conductive part 333, and the surface-mounted switch 33 is triggered, and thus, the circuit board 32 electrically connected to the surface-mounted switch 33 outputs a corresponding electronic signal to the electronic computer 4, thereby causing the electronic computer to perform the corresponding functions.
In particular, during the deformation of the metal dome elastic body 332, the portion of the metal dome elastic body 332 corresponding to the elastic conductive member 333, in addition to contacting the conductive contact portion 3331 of the elastic conductive member 333, pushes the conductive contact portion 3331 from the bottom to the top, so as to deform the arm portions 3332 of the elastic conductive member 333 toward the circuit board 32, since the elastic conductive member 333 is spaced from the circuit board 32 by the distance D, the metal dome elastic body 332 has a buffer space during the process of striking the elastic conductive member 333, so that the noise generated by the metal dome elastic body 332 striking the elastic conductive member 333 is reduced, and the comfort of the user operating the touch panel module 3 is improved.
In addition, the spacing distance D between the elastic conductive element 333 and the circuit board 32 may also be set according to practical application requirements, for example, the spacing distance D between the elastic conductive element 333 and the circuit board 32 is determined by matching with the deformation amount of the metal dome elastic body 332, so as to prevent the elastic conductive element 333 from being excessively deformed when being pressed by the metal dome elastic body 332, which may affect the hand feeling of the user pressing the touch pad module 3. Preferably, but not limited thereto, the conductive contact portion 3331 of the elastic conductive member 333 has a hollow region 3333 therein, i.e., the conductive contact portion 3331 is hollow, which also helps to reduce noise generated by the metal dome elastic body 332 striking the elastic conductive member 333.
In addition, when the user no longer touches the touch pad module 3, the first end 34 of the touch pad module 3 swings upward relative to the triggering portion 46 according to the elastic force of the metal dome elastic body 332 and/or the elastic force of the supporting structure 47, and finally, the shape of the metal dome elastic body 332 is restored, and the conductive contact portion 3331 of the elastic conductive member 333 is also restored to the original shape as shown in fig. 10 because the conductive contact portion is not pushed by the metal dome elastic body 332 any more.
However, the above embodiments are merely examples, and those skilled in the art can make various modifications and equivalents according to the actual application. For example, although the touch panel module 3 in the above embodiment does not contact the base conductive part 3311 at the portion of the metal dome elastic body 332 corresponding to the base conductive part 3311 vertically when the touch panel module 3 is not pressed, it may be alternatively designed that the portion of the metal dome elastic body 332 corresponding to the base conductive part 3311 vertically comes into contact with the base conductive part 3311 when the touch panel module 3 is not pressed.
For another example, the touch pad module may be designed to be independent of an input device outside the electronic computer. Referring to fig. 12 and 13, fig. 12 is a schematic view illustrating an application of a touch pad module according to another preferred embodiment of the present invention, and fig. 13 is a schematic view illustrating a partial structural cross-sectional concept of the touch pad module shown in fig. 12, wherein the touch pad module 3 ' of the present preferred embodiment is substantially similar to that described in the previous embodiment, and will not be described herein again, but the difference is that the touch pad module 3 ' further includes a triggering portion 37, a supporting structure 38, and a frame 36 for accommodating the upper cover plate 31, the colloid 39, the circuit board 32, and the surface-mounted switch 33, and the triggering portion 37 may be convex or flat and integrally formed with the frame 36, or may be an element additionally disposed in the frame 36, wherein the touch pad module 3 ' may be connected to the desktop computer 6 through a signal transmission means 5, such as a Universal Serial Bus (USB).
The above-mentioned embodiments are merely preferred embodiments of the present invention, which are not intended to limit the scope of the present invention, and therefore, all equivalent changes and modifications that do not depart from the spirit of the present invention are intended to be included within the scope of the present invention.
