Detailed description of the invention
Fig. 1 is the schematic diagram of the side key structure of one embodiment of the invention.
Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Fig. 1 is the schematic diagram of the side key structure of one embodiment of the invention.Side key structure shown in FIG. 1 includes the first key
Shell 1, side switch 2 and metal dome 3；
First key-press shell 1 is equipped with key slot 11, and side switch 2 is inserted into the first key-press shell 1 by key slot 11；
Side switch 2 includes keycap 21 and key core (unmarked), and key core includes soft key core 221 and hard key core 222, soft key
Core 221 and hard key core 222 are structure as a whole, and keycap 21 is fixedly connected with soft key core 221；
The bottom end of hard key core 222 is contacted with metal dome 3.
The key core of the embodiment of the present invention is made of soft key core 221 and hard key core 222, and soft key core 221 can be with key
The relatively firm fixation of cap 21.After applying external pressure to keycap 21, external pressure can be along keycap 21 --- soft key core
221 --- the direction of hard key core 222 is transferred to metal dome 3.
Since hard key core 222 has preferable rigidity, be conducive to the conduction of key active force, therefore compared to only by soft
Conventional keys core made of material, side key structure provided in an embodiment of the present invention have better side switch feel.
Limiting slot 12 is equipped in first key-press shell 1.
The width of the widest part position 2211 of soft key core 221 is greater than the groove width of key slot 11, and key core is located at 11 He of key slot
In limiting slot 12.
When key core is installed, the widest part position of soft key core 221 is located inside limiting slot 12, prevents key core from falling from key slot 11
It falls.
Before keycap 21, soft key core 221 and hard key core 222 are packed into the first key-press shell 1, to will be to above-mentioned three
It is fixed.Can be fixed by soft key core 221 and hard key core 222 using Double-color integrated moulding process, reuse glue or
Keycap 21 and soft key core 221 are adhesively fixed by other adhesives, can also according to the actual situation, using other applicable patterns
Keycap 21 and soft key core 221 is fixed.
In practice, the structure of the bonding site of keycap 21 and soft key core 221 is designed, is set in 21 bottom of keycap
There is one first groove structure, correspondingly, setting one and matched first protrusion of the first groove structure at the top of soft key core 221
Structure.It, can be in the first groove structure inner surface coating glue of keycap 21 and/or the first of soft key core 221 when bonding
The surface coating glue of bulge-structure, is combined closely the two by way of gluing and grafting.
In addition, also being designed the structure of soft key core 221, in the bottom of soft key core 221, setting one second is recessed
The top of slot structure, hard key core 222 can be plugged in the second groove structure, above structure realize soft key core 221 with
The strong bond of hard key core 222.
Key slot 11 can be located on the roof of the first key-press shell 1.
The embodiment of the present invention is further improved the structure of side switch to increase the waterproof performance of side key structure, can
To include following two improved procedure:
First way forms one side wall through-hole, limit by one end of limiting slot 12 through the side wall of the first key-press shell 1
The upper side wall of position slot 12 is connected to the lower slot of key slot 11, and side key structure further includes the second key-press shell 4 and waterproof double-sided adhesive 5,
The side of waterproof double-sided adhesive 5 is pasted on the first key-press shell 1 around lateral through aperture, and the other side of waterproof double-sided adhesive 5 is pasted on
On the inner wall of second key-press shell 4.
Further, run channel 13, the upper slot of run channel 13 and the lower wall of limiting slot 12 are additionally provided in the first key-press shell 1
Connection, key core are located in key slot 11, limiting slot 12 and run channel 13.
The second way is equipped with water-proof silica-gel 6 inside side key structure.Specifically, the periphery of water-proof silica-gel 6 is fixed on
On the inner wall of one key-press shell 1, the bottom end of hard key core 222 fits in the upper wall of water-proof silica-gel 6, and the upper wall of metal dome 3 fits in
The lower wall of water-proof silica-gel 6.
The lower wall of metal dome 3 fits in circuit board, in order to increase the intensity of circuit board, it will usually be laid with below circuit board
One reinforcing plate, and circuit board and reinforcing plate are fixed, the sticking two-faced adhesive tape below reinforcing plate later, using double-sided adhesive by circuit board
It is fixed on first shell inner wall, is may be also secured on the second key-press shell 4 with reinforcing plate.In practice, if by above-mentioned side switch knot
Structure fixation uses on mobile terminals, such as is fixed on mobile phone and uses, then metal dome 3 may be also secured on mobile phone center.
In the embodiment of the present invention, the setting of waterproof double-sided adhesive 5 and water-proof silica-gel 6 can effectively enhance the anti-of side key structure
Aqueous energy.
Side key structure in the embodiment of the present invention can be applied to mobile terminal, use on mobile terminals.User makes
When with mobile terminal, preferable side switch sense of touch can be experienced.In addition, since used side key structure has preferable waterproof
Property, therefore can protect the devices such as the circuit board in mobile terminal, display screen, can effectively extend mobile terminal uses the longevity
Life.
In conclusion according to the present invention, improving side key structure, the key cored structure of side switch is specifically improved, is used
Key core include soft key core and hard key core two parts, soft key core and hard key core are structure as a whole, keycap and soft key
Core is fixedly connected, and the bottom end of the hard key core is contacted with the metal dome.Since hard key core can preferably conduct key
Active force, soft key core have the characteristics that easy for installation, therefore the present invention is while realization facilitates installation, can preferably by
Key active force is transferred to metal dome, ensure that user to the sense of touch of side switch.
Furthermore it is possible to the side key structure of the embodiment of the present invention is applied to mobile terminal, due to used side key structure
With preferable waterproofness, therefore it can protect the devices such as the circuit board in mobile terminal, display screen, effectively extension mobile terminal
Service life.
