Embodiment
For just your auditor to the technical problems to be solved in the utility model, shape, constructing apparatus feature and effect thereof, do further understanding and understand, lift a preferred embodiment and conjunction with figs. now, be described in detail as follows:
Be generally used in the optical profile type mouse of desktop computer, usually move this mouse by the user, and the mouse mat of this mouse below is motionless, by moving of this mouse, pass on movable signal to receive for a computer apparatus, this computer apparatus can recomputate and draw a new slider position on this computer screen after receiving this movable signal, so, can reach the purpose of moving cursor.The utility model is then opposite with the action of aforementioned conventional mouse, it makes the Trackpad pad on the Trackpad vernier location structure move, and this location structure body motionless (being traditional mouse) so, can reach above moving cursor and certain purpose of moving equally.
See also shown in Fig. 1,2, it is a most preferred embodiment of the Trackpad vernier location structure on a kind of portable computer of the present utility model, it is located at a rectangular aperture 13 places of a portable computer 10 keyboards 11 below housings 101, the outside segment distance of edge extends downwards respectively and is provided with driving fit element 131 around housing 101 back sides of this rectangular aperture 13, as: flange.Be respectively equipped with a Trackpad pad 20 in this rectangular aperture 13, one supporting seat 21 and an optical circuit substrate 25, wherein upper limb is respectively equipped with another driving fit element 211 around this supporting seat 21, as: flange, these another driving fit elements 211 just can make these supporting seat 21 driving fits be embedded in the driving fit element 131 of these housing 101 inner faces, and this Trackpad pad 20 is arranged on this supporting seat 21, and expose in this rectangular aperture 13, and can accept to point 40 driving and on this supporting seat 21, move freely by the user, this Trackpad pad 20 is because of being subject to the restriction of these another driving fit elements 211 around this supporting seat 21 simultaneously, and can prevent that it from going beyond the scope when mobile and clamp (as shown in Figure 2).
In the present embodiment, be respectively equipped with a hollow column 22 downwards around this supporting seat 21, these column 22 outside sheathed flexible members 23 respectively, as: coil spring.And these column 22 hollow interior, then corresponding just insertion one is positioned on another column 24 of these portable computer 10 keyboards 11 below drain pans 102.
In the present embodiment, the area of this optical circuit substrate 25 is less than the area of this supporting seat 21, and is installed in these supporting seat 21 belows between this drain pan 102.Be respectively equipped with a microswitch 251, an optical sensing apparatus 252 and required electronic component 255, the circuit of normal operation thereof on this optical circuit substrate 25.And this optical sensing apparatus 252 is made of the lens 254 that a light-emitting component 253, an image capture element (not shown) and just can be located on this optical sensing apparatus 252.When the through hole 212 of light source on this supporting seat 21 of this light-emitting component 253 was projected to 20 on this Trackpad pad, 20 on this Trackpad pad was gone up the images that throwed and just be can be this image capture element and capture.Again and since this column 22 sheathed flexible member 23 length a little more than the top (as shown in Figure 2) of this microswitch 251, when this Trackpad pad 20 was moved, this supporting seat 21 can not touch this microswitch 251, and produced the situation of misoperation.
The member that nationality is above-mentioned, its mode of operation is the vernier on these portable computer 10 screens 103, pointed 40 by the user and move this Trackpad pad 20 and after producing movable signal and conveying to this portable computer 10, this computer 10 promptly receives this movable signal, and recomputate and draw a new slider position on this firefly power 103, this vernier just is moved and arrives a new vernier destination.If when choosing, as long as finger 40 light these Trackpad pads 20 of pressing, at this moment, this supporting seat 21 will down be forced down because of the effect of flexible member 23 simultaneously, and move down this microswitch 251 of light pressure, and then reach the purpose of choosing.After finger 40 unclamps this Trackpad pad 20 of gently being pressed, this supporting seat 21 promptly by around flexible member 23 original height and position that rebounds, form and prepare the state that clicked once more.
In the present embodiment, the central spot of this Trackpad pad 20 is provided with a cross mark 201 (as shown in Figure 1), it is in order to aim at a set respectively label symbol 132 on this rectangular aperture 13 outer rim all around, and acting as of this rectangular aperture 13 makes this Trackpad pad 20 can expose outside this housing 101, so that the user point 40 can be on the central point of this Trackpad pad 20, and, moving this Trackpad pad 20, and then reach the purpose of moving cursor by the moving of this finger 40.
In the present embodiment, see also shown in Figure 1, the lower left of these keyboard 11 below housings 101 is respectively equipped with a left button 30 and a right button 31, this left button 30 positioning key that promptly makes zero, be connected with a signal wire (end shows among the figure) on this optical circuit substrate 25, it is not put in order to pin this left button 30 when user's a finger (not shown), and another finger 40 is when moving this Trackpad pad 20, vernier on this screen 103 can't moving and moving cursor (i.e. the temporary transient inefficacy of the movable signal of this Trackpad pad 20 can't be conveyed to computer 10) because of this Trackpad pad 20, and this effect is the position that will adjust this Trackpad pad 20, promptly so-called flyback action.Usually run into the situation that needs to adjust these Trackpad pad 20 positions, in the time of near the slider position on this screen 103 is positioned at screen 103 central authorities, and the cross mark 201 on this Trackpad pad 20 does not just need when being near the position that is positioned at the central point of this rectangular aperture 13.
Moreover, the another kind of method of adjusting these Trackpad pad 20 positions, be when making this portable computer 10 just end machine, slider position all is set at the middle position of this screen 103, at this moment, cross mark 201 on this Trackpad pad 20 should be arranged on the center position place of this rectangular aperture 13, if cross mark 201 central points on this Trackpad pad 20, be not when the center position place of this rectangular aperture 13, as long as move this Trackpad pad 20, make its central point on the center position of this rectangular aperture 13, and then gently press this left button 30 to send a signal, slider position on this screen 103 is repainted in this screen 103 central authorities, can finish the flyback action of adjusting these Trackpad pad 20 center position.In addition, this right button 31 is connected with another signal wire (not shown) on this optical circuit substrate 25, and this right button 31 is equivalent to the right button on traditional mouse, has identical effect.
In addition in the present embodiment, the formula software that includes on this optical circuit substrate 25 need be done some adjustment, in order to prevent that when this Trackpad pad 20 was up mobile, the vernier on this screen 103 can produce the phenomenon that moves down.
The above, only be best specific embodiment of the present utility model, only feature of the present utility model is not limited thereto, and anyly is familiar with this skill person in the utility model field, can think easily and variation or modification, all should be encompassed in claims scope of the present utility model.
