Embodiment
Come a kind of mobile phone navigation key of the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment, but can not limit protection range of the present utility model with this.
For the mobile phone navigation key that the utility model disclosed, please see Figure 3 earlier, Fig. 3 is the structural representation of a kind of mobile phone navigation key of the utility model.As seen from the figure, mainly include roller 31, pedestal 32, sensitive switch 32, rolling switch 33 and the base plate 35 of band roller bearing on the mobile phone navigation key structure of the present utility model.
Be provided with a polygonal hole on the side on the top of rolling switch 33, the upper end of pedestal 34 is provided with groove, and the pressure contact on the described sensitive switch 32 is arranged at the top of sensitive switch.
One end of the roller bearing part of the roller 31 of band roller bearing is rounded, and the other end is polygon, and rounded roller bearing one end frame extend on the pressure contact of sensitive switch 32 after on the pedestal 34, is polygonal roller bearing one end and extend in the rolling switch 33.
The structure of rolling switch is divided into standing part and movable part, as shown in Figure 4 and Figure 5, Fig. 4 is the rolling switch internal structure standing part structural representation of a kind of mobile phone navigation key of the utility model, and Fig. 5 is the rolling switch internal structure movable part structural representation of a kind of mobile phone navigation key of the utility model.Three metal contacts 41,42,43 that the standing part encapsulation links to each other with three pins.Be packaged with a rotating disk in the movable part, be fixed with a metal slip ring 51 on the rotating disk, the contact 52 of three protrusions on the metal slip ring 51, the center of rotating disk is a polygonal hole, polygon one end of roller bearing is inserted in the polygonal hole.When coming the rotation roller axle, can drive rotating disk and rotate by roller.Contact on the metal slip ring on the rotating disk is according to the direction of rotating, three metal contacts that three pins of conducting according to certain rules link to each other are two sheet metals wherein, control cell phone keyboard matrix circuit two-way Closing Switch according to the electric signal that three pins of roller switch 33 are exported.Be positioned at the polygon aperture of center of turntable, the roller bearing of being convenient to an end of the roller control rolling switch that just in time is placed in one.Rotation by roller during use drives dial rotation, sends the signal that moves or move down to keyboard.Roll before the roller and after roll realize respectively page option before turn over and after turn over.Wherein said page option is not limited to tabulation, can be many palaces lattice menu of various patterns, text, picture, video.This electricity piece both can also can respond by many lattice in single lattice response, rolled slightly to single lattice response, was equal to clicking of traditional navigation key; Continuous rolling is that many lattice responses are equal to the multi-hit of traditional navigation key.
The pin of sensitive switch 32 is drawn from the another side of base plate 35 and is connected on the cell phone keyboard matrix circuit, and the pin of described rolling switch 33 is also drawn on the matrix circuit that is connected to cell phone keyboard from the another side of base plate 35.
The volume of roller type navigation key according to the size of mobile phone can do very little, the navigation key width is the order of magnitude of 5-7mm in the reality, the order of magnitude of height 7-10mm, the thickness 7-10mm order of magnitude, the order of magnitude of roller widths 2-4mm, the order of magnitude of roller diameter 5-8mm.See on the whole with the common key-press size similar, thereby allow roller type navigation bond energy to be installed on the position that mobile phone needs.
The roller of tape spool in the utility model is the transmission device, as navigation key, and control rolling switch during rolling, control sensitive switch when pressing.
Pedestal prevents that roller from moving forward and backward, better firm roller.Sensitive switch for a kind of packaged fine motion formula switch, is shaped as long cubic, selects enter-key signal for the input of cell phone keyboard matrix, plays the support roller effect simultaneously.The sensitive switch of this cube column wherein one side has two bumps, links to each other with the cell phone keyboard matrix circuit, to keyboard input push button signalling, wherein Dui Ying another side is the touch point of switch, is mechanical device, in spring is arranged, closing of circuit when pressing gently, the cut-out circuit of upspringing automatically during release.The closure of sensitive switch is directly controlled by the roller bearing of roller, and the roller bearing of roller places on the sensitive switch, and when roller was pushed, roller bearing extruding sensitive switch made it to open and close the acknowledgement key function that realizes mobile phone navigation key.
Rolling switch rises according to different roll modes and to move or to move down (move to left or move to right) navigation function on the cursor.
Base plate, the immobilising device effect.
As shown in Figure 3, Fig. 3 is the structural representation of a kind of mobile phone navigation key of the utility model.Among the figure: 32 is sensitive switch, and 33 is rolling switch, 31 rollers for the band roller bearing, and 34 is pedestal, 35 is base plate.Pedestal 34, sensitive switch 32, rolling switch 33 is fixed on the base plate 35, sensitive switch 32, the circuit pin of rolling switch 33 links to each other with the keyboard matrix circuit of mobile phone, one end of the roller 31 of band roller bearing is that the roller bearing of polygonal cross-section is placed in the changeable shape hole, rolling switch center, is convenient to control rolling switch and rolls 33, and the other end of the roller 31 of band roller bearing is that the roller bearing of circular cross-section is controlled sensitive switch by 34 of the pedestals on the chassis on sensitive switch 32.
Among the embodiment, it is HWT that sensitive switch 32 adopts the brand of device, the three-dimensional column of model WK-01[], also can adopt brand DONG HAI, model is small-sized sensitive switch [rectangular-shaped]; Rolling switch 33 is an encoder, employing be: the U.S. male MX 05[specification of brand is 5mm], also can adopt the encoder of brand HWT model BM-050.
The roller switch that the utility model is used in a band rubber tire replaces the press-type button of simple function, just can conveniently realize stirring up and down of mobile phone browser interface, and is flexible, and less to the device wearing and tearing, practicality is very strong.The above only is a preferable implementation column of the present utility model, is not to be used for limiting practical range of the present utility model, and all equivalences of doing according to the content of the utility model claim change and modify, and all should be technology category of the present utility model.
