Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
Fig. 1 is the single-hand operated keyboard structure in the utility model, as shown in the figure, this single-hand operated keyboard structure comprises the operation body 1a that an insulating material is made, and vertically its end face is provided with two through holes 11, be used for ccontaining metal bar 2, the bottom 22 of metal bar 2 is connected with the signal wire of printed circuit board (PCB).End face at this operation body 1a has set firmly a sheet metal 3a, and this sheet metal 3a is electrically connected with printed circuit board (PCB).Wherein, under original state, the top 21 of metal bar 2 does not contact with this sheet metal 3a.Apply external force at the end of sheet metal 3a during use it is bent downwardly, the top 21 of the metal group 2 below it contacts the Continuity signal line.
Fig. 2 is the vertical view of another embodiment of the present utility model, as shown in the figure, present embodiment is with the difference of embodiment 1: the axis (vertical paper direction) with this operation body 1b is the center, is arranged with a cross rolling groove 12b at the end face of operating body 1b.The center of this rolling groove 12b and respectively be provided with a through hole 11 away from four ends of axis, metal bar 2 vertically is arranged in this through hole 11, and the bottom 22 of this metal group 2 is electrically connected with printed circuit board (PCB).Set firmly a cross sheet metal 3b identical with its shape in rolling groove 12b, this sheet metal 3b is electrically connected with printed circuit board (PCB).Sheet metal 3b does not contact with the top 21 of metal bar 2 under the original state.As shown in Figure 3, the sidewall of this rolling groove 12b is a circular arc, and the spacing at top, two side is less than the diameter of ball.Card is established a slidably ball 4 in rolling groove 12b, and it is positioned at the top of this sheet metal 3b.Ball 4 makes it to contact with metal bar 2 after pressing down sheet metal 3b, thereby the Continuity signal line sends signal.Wherein, this operation body 1b and ball 4 all are that insulating material is made.
As shown in Figure 4, the center of this sheet metal 3b is provided with a recessed arc surface 31b, and this arc surface 31b matches with the surface of ball 4.Respectively be provided with a downward-sloping from inside to outside transitional slope 32b from the outward extending four direction of arc surface 31b.Respectively be provided with the downward-sloping transitional slope 33b of an ecto-entad at sheet metal 3b away from four ends of center line, this transitional slope 33b is convenient to press down when ball 4 slides the outer end of sheet metal 3b in track.The surface of contact of transitional slope 32b and 33b lifting sheet metal 3b and metal bar 2 guarantees that it does not contact mutually before operation.
Fig. 5 is an operation chart of present embodiment, and solid line represents that ball 4 does not move to before the transitional slope 33b, and the end of sheet metal 3b does not contact with the top 21 of the metal bar 2 of its below.When dotted line represented that ball 4 moves to transitional slope 33b, the end of sheet metal 3b contacted with the top 21 of metal bar 2, thereby sends signal.
On mobile phone, be applied as example with the one-handed performance bond structure in the present embodiment, suppose that the ball signal that contact point sent that triggers that moves upward is S+, move on the cursor; The signal that contact point sent that ball moves downward triggering is S-, and cursor moves down; The ball signal that contact point sent of motion triggers left is SL, cursor left; The signal that contact point sent that ball moves right triggering is SR, cursor right; The signal that contact point sent that ball triggers in the center is S0, this S0 signal indication confirmation signal.With the dialing interface is example, and dialed digit on the screen distributes as shown in Figure 6, enter this interface after the cursor acquiescence be positioned at numeral " 5 ".With the numeral " 1 " in the number " 110 " is example, utilizes one-handed performance bond structure control cursor to move.The user moves to left ball by singlehanded thumb, and signal SL is sent in left contact point connection, and cursor moves and moves to left to numeral " 4 ".Return ball and move on to the initial position, last contact point is communicated with and sends signal S+, moves to numeral " 1 " on the cursor.Return ball to initial position (that is, the body center) and press down ball, thereby middle contact point is communicated with and sends the input that signal S0 finishes numeral " 1 ".
As shown in Figure 7, the difference of present embodiment and embodiment 2 is: the single-hand operated keyboard structure in the present embodiment comprise that also one is fixedly arranged on the top cover 5 at operation body 1 top, this top cover is provided with a groove 51 and cooperates with rolling groove 12b, and ball 4 cards are established and operated between body 1 and the top cover 5.Wherein, the shape that the roller track cross section that rolling groove 12b and groove 51 constitute is not limited to mention in the present embodiment can be square shape, circle, major segment, perhaps arch.
As shown in Figure 8, the difference of present embodiment and embodiment 2 is: the axis with operation body 1c is the center, and symmetry is arranged with a M shape sliding tray 12c.And the sheet metal 3c of one meter font matches with this sliding tray 12c.Correspondingly, respectively offer a through hole 11 at the end of rolling groove 12c and be used for ccontaining metal bar 2, set up to nine with the signal wire that the bottom 22 of metal bar 2 contacts.Remainder is identical with embodiment 2.
Except that mobile phone, the single-hand operated keyboard structure in the utility model also is applicable to multiple mancarried electronic aid, game machine for example, palm PC etc.
Though more than described embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
