Detailed description of the invention
Fig. 1 is a kind of cross-sectional view of key in the embodiment of the present application.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiment is some embodiments of the present application, instead of all the embodiments.Based on this Shen
Please in embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall in the protection scope of this application.
A kind of key and mobile terminal provided by the embodiments of the present application, mobile terminal can be smart phone, computer, more matchmakers
Body player, electronic reader, wearable device etc..
A kind of key and mobile terminal provided by the present application is discussed in detail below by specific embodiment is enumerated.
Referring to Fig.1, show a kind of key of the embodiment of the present application, the key include keycap 10, key support 11, every
From bag 12 and press component 13；
The key support 11 is provided with key hole 111；
The keycap 10 is in the key hole 111；
The sack of the isolation pocket 12 is fixedly connected with the inner wall of the key hole 111；
Along the pressing direction of the keycap 10, the projection of the press component 13 projected with the keycap 10 is at least partly
It is overlapped.
Specifically, as shown in Figure 1, a kind of key disclosed in the embodiment of the present application include keycap 10, key support 11, every
From bag 12 and press component 13.Keycap 10 is the part that user's finger touches contact, has the press surface A contacted with finger, is led to
Often for the ease of the blind operation of user, some salient points can be set on press surface A.Key support 11 is the fixed bracket of keycap installation
Structure, which can undertake cradling function by the center either shell of mobile terminal, on key support 11
Key hole 111 is offered, keycap 10 is inlaid in key hole 111, keycap 10 and 111 clearance fit of key hole, when finger presses
When touching press surface A, keycap 10 can slide in key hole 111.Isolation pocket 12 be can elastic telescopic deformation film or soft
Fexible film made of property material, isolation pocket 12 are set between the side wall of keycap 10 and the inner wall of key hole 111, isolation pocket 12
Sack be fixedly connected with the inner wall of key hole 111.The sack of isolation pocket 12 can be with the first side of key hole 111 or second side
