Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of press-key structure of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of key base.
Embodiment
Below with reference to drawings and Examples, the utility model is described further, but protection range of the present utility model should not be limited with this.
For convenience of description and understand the technical solution of the utility model, below illustrate that the orientation that the noun of locality used all is shown with accompanying drawing is as the criterion.
As shown in Figure 1 to Figure 3, a kind of press-key structure of the present utility model, it is for portable electron device, also can be used for other electronic installations except portable electron device.A kind of press-key structure of the present utility model comprises key base 1 and keying body 2.Described key base 1 offers location hole 111, described keying body 2 to be partially housed in location hole 111 and can along location hole 111 reciprocating motion.
Key base 1 comprises fixed head 11 and two fixing holes 12, and the middle part of described fixed head 11 offers location hole 111, and described fixing hole 12 is positioned at the edge of fixed head 11 and integrative-structure with it.The periphery that fixing hole 12 can be distributed in fixed head 11 symmetrically also can be arranged on the periphery of fixed head 11 unevenly.Fixing hole 12 is fixedly connected with by the installing component of connector with preset electronic device, and connector can be screw or rivet.
Keying body 2 comprises the press section 21 be positioned at above fixed head 11 and the support portion 22 being contained in location hole 111.The shape of fixed head 11 and the mating shapes of press section 21, and the area of fixed head 11 is slightly larger than the area of press section 21, thus, fixed head 11 both can limit the motion of press section 21 in the vertical direction, the pressing stroke of button is limited, operation is more accurate, can save installing space simultaneously, simple and compact for structure.
The material of press section 21 is silica gel.Because silica gel has certain elasticity, therefore when operating press section 21, feel is more comfortable.And silica gel can make it have different apparent colours by changing composition, therefore easily makes the outward appearance of press section 21 improve, thus button can be made to coordinate mutually with the overall appearance of portable electron device, use more flexible.The upper surface of described press section 21 is inclined-plane, and in order to match with use habit, operating aspect is comfortable.The upper surface of described press section 21 is provided with the dimpled grain for identification of function, and the shape of dimpled grain is the identification of function mark that button is corresponding, makes user visually more directly perceived.
Support portion 22 comprises support column 221 and supporting seat 222, and support column 221 to be contained in location hole 111 and can along location hole 111 reciprocating motion.Described support column 221 upper end is run through location hole 111 and is fixed in the bottom of described press section 21, and described support column 221 lower end is movably connected on supporting seat 222.Support column 221 does along location hole 111 radial motion that axial motion can limit support column 221 simultaneously, in the process of pressing keys, operate more stable, exert oneself evenly.And in the installation process of button, in advance the installing component of fixing hole 12 with preset electronic device is fixedly connected with, thus key base 1 is fixedly mounted on preset electronic device.Keying body 2 is installed on the basis of the key base 1 fixed, and be easy to location during operation, simple installation is quick.
Supporting seat 222 is installed in the PCB substrate of preset electronic device, and the part that PCB substrate is positioned at supporting seat 222 has triggering position.The inside of supporting seat 222 is provided with cone shaped spring (not shown), and the small end of described cone shaped spring upward and the lower end being fixed in support column 221 returns back to original position for making press section 21 after operation.During the press section 21 of downward pressing keys main body 2, the support column 221 affixed with it, at the transmission moved downward of active force, drives cone shaped spring generation elastic deformation, and the bottom of support column 221 touches triggers position thus realizes triggering.When unclamping press section 21, the cone shaped spring being in compressive state upwards extends, and support column 221 is moved up, and the bottom of support column 221 is left and triggered position.
Change the elastic force of cone shaped spring, can change feel, the elastic force of button is also different.Frequency of utilization as button is little, and the elastic force of cone shaped spring is less, and as frequency of utilization is large, the elastic force of cone shaped spring is comparatively large, also can not be tired after so long-time use, ensure that comfortable feel.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned execution mode and revise.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
