Abstract
The invention provides a touch pad module, which comprises a circuit board, a switch and a conductive heightening piece. The switch is configured on the circuit board. The metal dome elastomer of the switch includes a first portion corresponding to the first conductive portion and a second portion corresponding to the second conductive portion. The metal dome elastic body deforms in response to an external force, so that the first portion contacts the first conductive portion. The conductive padding is located between the second conductive portion and the second portion of the metal dome elastomer such that a space is formed between the circuit board and the second portion of the metal dome elastomer. The distance can reduce the contact area between the metal dome elastic body and the circuit board, thereby reducing the noise generated by knocking the circuit board by the metal dome elastic body and further improving the comfort of a user during operation. In addition, the invention also provides an electronic computer with the touch pad module.
Description
Technical Field
The present invention relates to the field of input devices, and particularly 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, etc., and the storage capacities and the computing 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 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 the cursor 23 on the screen 22, or can press the touch pad module 1 to make the notebook computer 2 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 5 in a synchronous manner, fig. 2 is a conceptual diagram of the touch pad module shown in fig. 1 when not being pressed, fig. 3 is a conceptual diagram of the touch pad module shown in fig. 2 when being pressed, fig. 4 is a conceptual diagram of a partial structure cross section of the circuit board and the switch when the touch pad module shown in fig. 2 is not being pressed, and fig. 5 is a conceptual diagram of a partial structure cross section of the circuit board and the switch after the touch pad module shown in fig. 3 is being pressed. The housing 21 of the notebook computer 2 has an inwardly recessed frame 24, and a supporting structure 241 and a triggering portion 242 extending into the frame 24 are respectively disposed at two opposite sides in 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, as shown in fig. 5, in this way, 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 due 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 when the user presses the touch pad module 1, the deformed metal dome elastic body 131 contacts the circuit board 14 in addition to the first conductive portion 141, that is, the deformed metal dome elastic body 131 contacts the circuit board 14 with a large area of knocking, thereby generating unpleasant noise, and therefore, how to improve the above problems is a focus of attention of those skilled in the art.

Other detailed structures of the touch pad module 3 according to the embodiment of the invention will be described in further detail below.
Please refer to fig. 8, which is a schematic diagram illustrating a cross-sectional structure of the switch shown in fig. 7. The metal dome elastic body 332 of the present embodiment includes a first portion 3301 for the first conductive portion 321 and a second portion 3302 corresponding to the second conductive portion 322. Moreover, the touch pad module 3 of the present embodiment further includes a conductive pad-up 30, the conductive pad-up 30 is disposed on the circuit board 32 and located between the second conductive portion 322 and the second portion 3302 of the metal dome elastic body 332, and the conductive pad-up 30 is located between the second conductive portion 322 and the second portion 3302 of the metal dome elastic body 332, so that a gap G is formed between the circuit board 32 and the second portion 3302 of the metal dome elastic body 332, in the present embodiment, the gap G is, for example, 0.15 mm, but the present invention is not limited thereto. It should be noted that the conductive raised element is only disposed in the region between the second portion 3302 of the metal dome elastic body 332 and the second conductive portion 322 of the circuit board 32, and no conductive raised element 30 is disposed in the region between the first portion 3301 of the metal dome elastic body 332 and the first conductive portion 321 of the circuit board 32, i.e., the conductive raised element 30 does not extend into the region between the first portion 3301 of the metal dome elastic body 332 and the first conductive portion 321 of the circuit board 32.
Specifically, the conductive raised element 30 of the present embodiment has the first surface 301 and the second surface 302 opposite to each other, the first surface 301 of the conductive raised element 30 contacts the second portion 3302 of the metal dome elastic body 332, and the second surface 302 of the conductive raised element 30 contacts the second conductive portion 322 of the circuit board 32, and with such a structure design, the conductive raised element 30 can raise the metal dome elastic body 332 away from the circuit board 32 to form the gap G shown in fig. 8, in other words, the size of the gap G depends on the thickness of the conductive raised element 30, that is, in the present embodiment, the thickness of the conductive raised element 30 is, for example, 0.15 mm, but the present invention is not limited thereto.
The detailed operation of the touch pad module 3 when being pressed is further described below.
Referring to fig. 9 and 10, fig. 9 is a schematic cross-sectional view of a portion of the touch pad module and the frame shown in fig. 7 when being pressed. Fig. 10 is a conceptual sectional view of the switch shown in fig. 9. As shown in fig. 9, 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 46 with the supporting structure 47 as a fulcrum until the switch 33 abuts against the trigger 46 to deform the metal dome elastic body 332 in the switch 33. In the process of deformation of the metal dome elastic body 332, the first portion 3301 of the metal dome elastic body 332 corresponding to the first conductive portion 321 of the circuit board 32 contacts the first conductive portion 321, and the second portion 3302 of the metal dome elastic body 332 corresponding to the second conductive portion 322 of the circuit board 32 contacts the conductive pad-up 30, since the conductive pad-up 30 has conductivity, electrical conduction is formed between the first conductive portion 321, the second conductive portion 322 of the circuit board 32 and the conductive pad-up 30, and the switch 33 is triggered, so that the circuit board 32 electrically connected to the switch 33 outputs a corresponding electronic signal to the electronic computer 4, thereby enabling the electronic computer 4 to perform a corresponding function.
As described above, since the metal dome elastic body 332 of the switch 33 is lifted up in the direction away from the circuit board 32 so as to form the gap G between the second portion 3302 of the metal dome elastic body 332 and the circuit board 32, when the touch pad module 3 is pressed by a user to deform the metal dome elastic body 332, the contact area between the metal dome elastic body 332 and the circuit board 32 is reduced when the first portion 3301 of the metal dome elastic body 332 can reliably contact the first conductive portion 321 of the circuit board 32, and thus, the noise generated when the metal dome elastic body 332 strikes the circuit board 32 can be greatly reduced, and the comfort of the user can be further improved.
It should be noted that, in the embodiment, the gap G formed between the second portion 3302 of the metal dome elastic body 332 and the circuit board 32 by the conductive pad-up member 30 is 0.15 mm, which is only one embodiment of the present invention, in other embodiments, the gap G may be in a range greater than or equal to 0.1 mm and less than or equal to 0.5 mm, that is, the conductive pad-up member 30 with a thickness between 0.1 mm and 0.5 mm may be selected according to the actual requirement, so that the technical effects of reducing the noise generated by the metal dome elastic body 332 hitting the circuit board 32 and improving the comfort of the user can be achieved. In addition, in the present embodiment, the conductive pad-up member 30 is, for example, a rubber material, for example, the conductive pad-up member 30 of the present embodiment can be a rubber material such as a Pressure Sensitive Adhesive (PSA), a conductive silicone, an Anisotropic Conductive Film (ACF), a thermosetting conductive double-sided tape, and the like, but the invention is not limited thereto. In other embodiments, the conductive pad-up member 30 is, for example, a flexible conductive material, such as a conductive non-woven fabric, but the invention is not limited thereto.
Please refer to fig. 11, which is a schematic diagram illustrating a top view of the switch shown in fig. 8. As shown in fig. 11, the circuit board 32 of the present embodiment further includes a shaft center a, and the first conductive part 321 and the second conductive part 322 of the circuit board 32 are sequentially arranged in a concentric ring shape along the radial direction R from the shaft center a, in the present embodiment, the first conductive part 321 and the second conductive part 322 are respectively in a closed ring shape, the second conductive part 322 surrounds the first conductive part 321, and the conductive elevating element 30 is also in a closed ring shape and covers the second conductive part 322 of the circuit board 32. It should be noted that the configurations of the first conductive portion 321, the second conductive portion 322 and the conductive elevated element 30 are only one embodiment of the present invention, and the present invention is not limited to the configurations of the first conductive portion 321, the second conductive portion 322 and the conductive elevated element 30, and the configurations of the first conductive portion 321, the second conductive portion 322 and the conductive elevated element 30 may be different according to the requirements of the actual situation, and in addition, in the case that the structural strength of the conductive elevated element 30 is sufficient to form the gap G between the second portion 3302 of the metal dome elastic body 332 and the circuit board 32, the conductive elevated element 30 may not need to completely cover the second conductive portion 322 of the circuit board 32.
Please refer to fig. 12, which is a schematic top view of a touch pad module according to another embodiment of the present invention. As shown in fig. 12, the touch pad module 3a of the present embodiment is similar to the touch pad module 3 shown in fig. 6 to 11, except that the conductive pad 30a of the touch pad module 3a of the present embodiment is a ring structure, and the ring structure has at least one opening O to form a C-shaped ring structure, and a portion of the second conductive portion 322 of the circuit board 32 is exposed from the opening O of the ring structure. It should be noted that the above-mentioned ring structure having at least one opening O is only one embodiment of the present invention, and the present invention does not limit the number of the opening O, and the number of the opening O may be different according to the requirements of the actual situation.
