Description
Technical field
The present invention is relevant a kind of Trackpad, particularly about a kind of Trackpad of supporting double-side operation.
Background technology
Trackpad is because volume is little, cost is low, consumed power is low and long service life, therefore be widely used on each electronic product, for example mobile computer, mouse, MP3 player, mobile phone or the like even, as input media, user only need slides on level and smooth panel with finger or electric conductivity object (for example pointer) or contacts, cursor is produced relatively move, absolute coordinates moves or other extensibility function (for example virtual key function), can finish various inputs such as comprising character calligraph, rolling stripe coiling and button.Yet Trackpad is a level and smooth panel, and only supports the single face operation, therefore when carrying out button operation with virtual key, can't clear and definite operational motion be arranged as physical button.
For making button operation have the sensation of physical button, and support the operation of Trackpad, known technology to have two kinds simultaneously.First kind is button and Trackpad two elements for separating, product also be two elements in appearance for reality, shown in Figure 1A and Figure 1B.Second kind is button and Trackpad two elements for separating, but product be holistic element in appearance, shown in Fig. 2 A and Fig. 2 B.With reference to Figure 1A, when using button operation, directly import with physical button 100.With reference to Figure 1B, physical button 100 is raised the operational zone 110 that is Trackpad, comprise hand-written district 120, acknowledgement key 130, cancel key 140, directionkeys 150 and 152 and Chinese and English switch key 160 and 162.Though the device of this kind structure has the function of button and Trackpad simultaneously, be to use independently element of two difference, so the volume of product is big and cost is higher.With reference to Fig. 2 A and Fig. 2 B, by the perforation 220 at correspondent entity button place on Trackpad 210, make when pushing physical button 200, by the button detecting mechanism of 220 activation Trackpads, 210 belows of boring a hole, finish the button input.When desire uses touch control plate function to carry out handwriting input,, therefore can directly on physical button 200, carry out handwriting input because Trackpad 210 is positioned at the below of physical button 200.Though this kind structure is structure as a whole in appearance, but in fact the detecting of push button signalling is not to be carried out by Trackpad 210, therefore be keypress function or touch control plate function for what distinguish use, in design often based on keypress function, and sacrificed the function of Trackpad, cause the functional response of Trackpad slack-off with the usefulness variation, cause the inconvenience in the use, and, make cost effectively to reduce because button and Trackpad in fact still are two other elements of branch.
Therefore, a kind of Trackpad of supporting touch-control sensing and physical button, what people expected just.
Summary of the invention
Fundamental purpose of the present invention is to propose a kind of Trackpad of supporting double-side operation.
According to the present invention, a kind of Trackpad of supporting double-side operation comprises an inductor, one insulation course is positioned at the top of this inductor so that an operational zone to be provided, and one the button operation conductor be positioned at the below of this inductor, for connecting or, triggering keypress function near this inductor.
In one embodiment, this inductor is positioned at the upper strata of a printed circuit board (PCB), and the lower floor of this printed circuit board (PCB) comprises a lead, and this lead connects this inductor, makes this button operation conductor dbus cross and connects this lead and connect this inductor indirectly, triggers keypress function.
In another embodiment, this inductor is positioned at the upper strata of a printed circuit board (PCB), and this button operation conductor dbus is crossed near this printed circuit board (PCB) and near this inductor, triggers keypress function.
In another embodiment, this inductor comprises the capacitive sensing conductor that the one first spindle guide body and the second spindle guide body are formed, and one insulation course between this capacitive sensing conductor and this button operation conductor, have the cavity on this insulation course and allow this button operation conductor pass and connect this first spindle guide body and/or this second spindle guide body, trigger keypress function.
In different embodiment, this inductor comprises one first spindle guide body, one second spindle guide body, and an insulation course is between this first spindle guide body and the second spindle guide body, have the cavity on this insulation course and allow this second spindle guide body pass and connect this first spindle guide body, trigger keypress function.
The Trackpad of support double-side operation of the present invention is finished touch-control sensing and two kinds of different inputs of keypress function with single component, reaches the assembly that reduces electronic product, reduces cost and increase and use the purpose that goes up convenience.
