Detailed description of the invention
Understandable, below in conjunction with the accompanying drawings for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from
The present invention is further detailed explanation with detailed description of the invention.
Fig. 1 is the schematic diagram of the side key structure of one embodiment of the invention.Side key structure bag shown in Fig. 1
Include the first key-press shell 1, side switch 2 and metal dome 3；
First key-press shell 1 is provided with by keyway 11, and side switch 2 is by inserting the first key-press shell by keyway 11
In 1；
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, keycap 21 and soft key core 221
Fixing connection；
The bottom of hard key core 222 contacts with metal dome 3.
The key core of the embodiment of the present invention is made up of soft key core 221 and hard key core 222, soft key core 221
More can be firmly fixed with keycap 21.After keycap 21 is applied external pressure, external pressure can edge
The direction keycap 21 soft key core 221 hard key core 222 is transferred to metal dome 3.
Owing to hard key core 222 has preferable rigidity, the beneficially conduction of button active force, therefore phase
Than in the conventional keys core being only made up of soft material, the side key structure that the embodiment of the present invention provides has more preferably
Side switch feel.
It is provided with stopper slot 12 in first key-press shell 1.
The width of the widest part position 2211 of soft key core 221 is more than the groove width pressing keyway 10, and key core is positioned at
By in keyway 10 and stopper slot 12.
When key core is installed, it is internal that the widest part position of soft key core 221 is positioned at stopper slot 12, prevents key core
Drop from by keyway 10.
Before keycap 21, soft key core 221 and hard key core 222 are loaded the first key-press shell 1, right
Above-mentioned three is fixed.Double-color integrated moulding process can be used soft key core 221 and hard
Key core 222 is fixed, and re-uses glue or other adhesivess by bonding to keycap 21 and soft key core 221
Fixing, it is also possible to according to practical situation, to use other applicable patterns by keycap 21 and soft key core 221
Fixing.
In reality, the structure of keycap 21 and the bonding site of soft key core 221 is designed,
It is provided with one first groove structure bottom keycap 21, correspondingly, arranges one at the top of soft key core 221
The first bulge-structure mated with the first groove structure.Time bonding, can be at the first groove of keycap 21
Structure interior surface coating glue and/or the surface-coated glue of the first bulge-structure at soft key core 221,
Both are combined closely by the way of grafting by gluing.
It addition, also the structure of soft key core 221 is designed, set in the bottom of soft key core 221
Putting one second groove structure, the top of hard key core 222 can be plugged in the second groove structure, above-mentioned
Structure achieves the strong bond of soft key core 221 and hard key core 222.
May be located on the roof of the first key-press shell 1 by keyway 10.
The structure of side switch, in order to increase the water resistance of side key structure, has been done further by the embodiment of the present invention
Improve, can include following two improved procedure:
First kind of way, by one end of stopper slot 12 through the sidewall of the first key-press shell 1, forms one
Lateral through aperture, the upper side wall of stopper slot 11 connects with by the lower slotted eye of keyway 10, and side key structure also includes
Second key-press shell 4 and waterproof double faced adhesive tape 5, the side of waterproof double faced adhesive tape 5 is pasted on around lateral through aperture
On first key-press shell 1, the opposite side of waterproof double faced adhesive tape 5 is pasted on the inwall of the second key-press shell 4.
Further, being additionally provided with run channel 13 in the first key-press shell 1, the upper slotted eye of run channel 13 is with spacing
The lower wall connection of groove 12, key core is positioned at presses keyway 11, stopper slot 12 and run channel 13.
The second way, is provided with water-proof silica-gel 6 inside side key structure.Specifically, water-proof silica-gel 6
Periphery is fixed on the inwall of the first key-press shell 1, and the bottom of hard key core 222 fits in water-proof silica-gel 6
Upper wall, 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 at circuit
Lay an enhancing plate below plate, and circuit board and enhancing plate are fixed, paste double afterwards below enhancing plate
Face glue, uses double faced adhesive tape circuit board and enhancing plate to be fixed in the first inner walls, it is also possible to be fixed on
On second key-press shell 2.In reality, if using fixing for above-mentioned side key structure on mobile terminals, such as
Be fixed on mobile phone use, then metal dome 3 may be also secured on mobile phone center.
