Detailed description of the invention
The present invention is described in detail with embodiment below in conjunction with the accompanying drawings.
Refer to Fig. 1 to Fig. 3, a kind of keystroke fixing structure includes fore shell 1 and button 2.Fore shell 1
It is provided with button installing zone 12, docking screwed hole 11 and cincture and forms the convex of docking screwed hole 11
Go out portion 15..Docking screwed hole 11 is offered from first direction A and is positioned in button installing zone 12
Edge, protuberance 15 forms a boss 13 towards button installing zone 12 projection.
Button 2 includes stator 21 and the button rubber cushion 22 being connected with stator 21.Stator
21 offer at least one button through hole 211, and the position of its corresponding boss 13 arranges fastener
23.Button rubber cushion 22 includes the press section 221 corresponding with button through hole 211..
After stator 21 A in the first direction is assembled to fore shell 1, fastener 23 blocks with boss 13
Hold, thus prevent the relative fore shell 1 of button 2 from rocking along second direction B contrary with first direction A；
And then prevent button 2 B in a second direction being assembled to fore shell 1 from separating with fore shell 1.
In the present embodiment, touching for convenience, press section 221 is protruded and is arranged and be embedded in button through hole
In 211.Button 2 farther includes to be connected to the button cap 24 of press section 221.Button cap 24
Connection with press section 221 can use the mode that glue is bonding, it would however also be possible to employ other mode,
The present invention is without limitation.
Please with reference to Fig. 4 to Fig. 7, in the present embodiment, it is preferable that fastener 23 include for
Guide fastener 23 snap in boss 13 guidance part 231 and with the clamping part 232 of boss clamping.
Arranging of guidance part 231 facilitates button 2 rapid and convenient to be assembled to fore shell 1.Clamping part 232 is with convex
The way of contact of platform 13 preferred face contact, it is to avoid portable mobile termianl bears relatively during using
Rupture at clamping part 232 or boss 13 during big external impacts.
Preferably, both fastener 23 and stator 21 select identical elastomeric material integrated injection molding
Molding, makes buckling piece 23 have the most elastic and be prone to processing.
The docking screwed hole 11 of fore shell 1 setting and the back cover of portable mobile termianl (not shown)
The screwed hole (not shown) that (not shown) corresponding position is arranged is together by screw (not shown)
Fasten.
Please with reference to Fig. 8 to Fig. 9, owing to the size of fore shell 1 is relatively thin, docking screwed hole 11 is opened
It is located on the protuberance 15 that fore shell 1 is arranged.A part for protuberance 15 protrudes out to button installing zone
12 i.e. form boss 13.
Please refer to Fig. 7, owing to a part for protuberance 15 protrudes out to button installing zone 12,
The corresponding position of stator 21 arranges the arc gap 212 accommodating protuberance 15, fastener 23
The most right with arc gap 212.
Please with reference to Figure 10 to Figure 12, fore shell 1 farther includes multiple locating dowel 14, fixing
Sheet 21 farther includes multiple fixing mouth 213 being correspondingly arranged with locating dowel 14, and locating dowel 14 is overlapped
If to fixing in mouth 213 to prevent relative fore shell 1 A in the first direction of button 2 from shaking.
Stator 21 farther includes multiple connection post 214, and button rubber cushion 22 farther includes many
Individual be connected the connector 222 that post 214 is correspondingly arranged respectively；Stator 21 and button rubber cushion 22
Connect by connecting post 214 and connector 222.
Compared with prior art, the stator 21 of keystroke fixing structure of the present invention corresponding fore shell 1
Docking boss 13 position outside screwed hole 11 arranges fastener 23, and stator 21 is along first
Direction A is assembled to fore shell 1 to be made fastener 23 with boss 13 clamping thus reaches to prevent button 2 phase
The purpose that fore shell 1 is rocked along second direction B contrary with first direction A.And can be at not shadow
On the premise of ringing the intensity of fore shell frame, reach the effect of fixing main button, reduced mobile phone
Frame insufficient space in the design process, it is impossible to design buckle situation, be greatly improved hands
The serviceability of machine and quality, reduce the maintenance probability of mobile phone virtually, cost-effective, improves
The reliability of mobile phone.
The present invention further provides a kind of portable mobile termianl applying aforementioned keys fixed structure.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention,
Every equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion, or
Directly or indirectly being used in other relevant technical fields, the patent being the most in like manner included in the present invention is protected
In the range of protecting.
