Embodiment
Figure 1A is the decomposing schematic representation of press-key structure of the mobile computer of one embodiment of the invention, and Figure 1B is the assembling synoptic diagram of the press-key structure of Figure 1A.Fig. 1 C is the diagrammatic cross-section of the press-key structure of Figure 1B along the I-I line.Mobile computer has a housing 110, a display screen (not illustrating), a Trackpad 120 and a press-key structure 130.Trackpad 120 and press-key structure 130 are assembled in respectively on the housing 110, and the user is moving the cursor on the control display screen curtain to move/pull, click functions such as application program or window choosing by finger on the Trackpad 120.
Press-key structure 130 is assembled in the key zone T of Trackpad 120 belows, and its function is equivalent to the right and left key of mouse.Press-key structure 130 comprises a circuit board 140 and a button framework 150 at least.Circuit board 140 can be placed in the fluting 112 of housing 110.Circuit board 150 is electrically connected to a cursor control (not illustrating) with Trackpad 120.Circuit board 140 has first switch S 1 and second switch S2, for example is push switch or Piezoelectric switches, and wherein the position of first switch S 1 is corresponding to the left side of key zone T, and the position of second switch S2 is corresponding to the right side of key zone T.When pushing first switch S 1 or second switch S2, first switch S 1 can judge via cursor control (not illustrating) with the electrical functionality of second switch S2, to click or function such as On/Off application program, is not described in detail in this.
Structurally, button framework 150 integrated left side and the right sides that extend key zone T, just extend first switch S 1 of circuit board 140 and the top of second switch S2, and divide into a 150a of Left button portion, a 150b of right button portion and a butt shell fragment 150c of portion.In the present embodiment, button cover plate 160 can cover the key zone T of Trackpad 120 belows, that is covers button framework 150 and circuit board 140.The left side of button cover plate 160 and right side for example have two projections 162,164 (shown in Fig. 1 C), respectively corresponding first switch S 1 and second switch S2.The user can come function circuit plate 140 by the left side and the right side of pressing keys cover plate 160.
The 150a of Left button portion is corresponding to first switch S 1 of circuit board 140.The 150b of right button portion is corresponding to the second switch S2 of circuit board 140.The butt shell fragment 150c of portion is connected between first switch S 1 and second switch S2 of circuit board 140.Specifically, the two ends of the butt shell fragment 150c of portion connect 150a of Left button portion and the 150c of right button portion respectively, for example be a v-shaped structure,, and do not influence each other so that 150a of Left button portion and the 150b of right button portion are central pivot point start separately with the butt shell fragment 150c of portion.For convenience of description, below at button framework 150 detailed description.
Please refer to Figure 1A and Fig. 2, Fig. 2 is the backplan of the button framework of Figure 1A.Button framework 150 is a hollow out platy structure, and it has an outer frame 150d who connects Left button 150a of portion and the 150b of right button portion, so that have an open C in the button framework 150.The size of Trackpad 120 equals the size of open C haply, and button framework 150 can be fixed in Trackpad 120 in the open C.Button framework 150 also has a plurality of locking part F, for example is screw or perforation, can pass and is fixed on the housing 110 of mobile computer for locking part L.When Trackpad 120 is fixed in an outside surface of housing 110 by button framework 150, be available for users on the Touch Zone of Trackpad 120, operate, so that cursor moves.In addition, the 150a of Left button portion for example has a start window W1, corresponding to first switch S 1, so that the projection 162 of button cover plate 160 can be arranged in start window W1, and contacts first switch S 1 via pushing.The 150b of right button portion for example has another start window W2, corresponding to second switch S2, so that another projection 164 of button cover plate 160 can be arranged in start window W2, and contacts second switch S2 via pushing.
In addition, please refer to Figure 1A and Fig. 3, Fig. 3 is the backplan of the support plate of Figure 1A.In another embodiment of the present invention, press-key structure 130 can comprise that more one supports plate 170, and it is connected to respectively between button framework 150 and the circuit board 140.Support plate 170 suitable upwards anchorage force can be provided,, avoid false touch to move switch so that button framework 150 keeps suitable spacing with circuit board 140 down in the normality state.In addition, support plate 170 and also can improve the sensitivity of pushing, increase the user in operational sense of touch.
Supporting plate 170 is the plate body of strip, for example has two start window W1, W2, and its position and function are with respect to two start windows of button framework 150.In addition, the centre that supports plate 170 can have an opening 172, and the butt shell fragment 150c of portion of button framework 150 can be connected on the circuit board 140 via opening 172.In addition, the two ends of supporting plate 170 can be fixed on the casing 110 by locking part, that is to say that the two ends of supporting plate 170 are stiff end.Again, the two ends of supporting plate 170 for example are provided with two elastic arms 174, to increase elasticity.
In sum, press-key structure of the present invention utilizes butt shell fragment portion to be connected between first switch and second switch of circuit board.Therefore, the Left button portion of button framework and right button portion are separated and start separately by butt shell fragment portion, do not influence each other.Phenomenon and the button that can avoid seesaw takes place do not have shake-up or the not good situation generation of sense of touch, can avoid the user to push Left button and right button simultaneously yet, and the problem of moving together about producing.In addition, structurally, the button framework is integrated.Therefore, the user can assemble the button framework apace.
Though the present invention discloses as above with embodiment; right its is not in order to limit the present invention; have in the technical field under any and know the knowledgeable usually; without departing from the spirit and scope of the present invention; when doing a little change and retouching, so protection scope of the present invention is as the criterion when looking the claim person of defining.
