Abstract
The invention provides a mobile communication terminal and a key device thereof, which are used for solving the problem that the other side or corner of a key in the key device of the mobile communication terminal in the prior art is tilted when one side or one corner of the key is pressed. The key device comprises a silicone key layer on which a plurality of silicone key contact areas are formed, and discontinuous grooves are formed around each silicone key contact area. By the technical scheme, the problem that the other side or corner of the key is tilted when one side or one corner of the key is pressed is effectively solved.
Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of mobile communication terminal and key device thereof.
Background technology
At present the thickness of mobile communication terminal is more and more thinner, also makes the more and more narrow that the design space of button becomes, and the button of ultra-thin liding machine has become a thin slice basically and has been attached to the design on the face-piece.But can have the button good hand touch of the button of zone line than fringe region to the too close housing of such button, the button at edge is too near to housing, thereby the resistance to deformation power of sheet material causes feel bad greatly when pushing.To the bad problem of feel, generally be to add the resistance to deformation power that a circle groove in a disguised form reduces silica gel at the whole edge of pushing, thereby this in addition structure can also need not spur feasible the slim and graceful of change of pushing of the distortion of sheet material.But feel when improving, also brought push on one side or one jiao in addition on one side or one jiao of problem that warps, warping causes seeing the mouth of a river, just can button be buckled, scrape serious problem of appearance such as hand with nail.
Like application number is that 200510082941.5 application for a patent for invention just discloses a kind of button and had the shell of this button; This button includes a key body, and this key body has a positive and back side, and the back side of this key body is formed with a fixed part and a junction; This fixed part supplies to be fixed in a housing; This connecting portion is away from this fixed part, and and connect this housing with mobilizable mode, make that this key physical efficiency is that the strong point is done slightly swing with this fixed part.The present invention connects on this housing with mobilizable mode through this connecting portion, and makes this button that the situation of perk, distortion can not take place.Press-key structure with said structure is appointed the one side so there is pressing keys or one jiao, in addition on one side or one jiao of problem that warps.
In the prior art, the key device of mobile communication terminal is on one side of pressing keys or one jiao the time, in addition on one side or one jiao warp, for this problem, effective solution is not proposed as yet at present.
Summary of the invention
Main purpose of the present invention provides a kind of mobile communication terminal and key device thereof, with the key device that solves mobile communication terminal in the prior art on one side of pressing keys or one jiao the time, in addition on one side or one jiao of problem that warps.
To achieve these goals, according to an aspect of the present invention, a kind of key device of mobile communication terminal is provided.
The key device of mobile communication terminal of the present invention comprises: silica gel key-press layer, be provided with several silica gel push-button contact regions, and around each silica gel push-button contact region, be provided with discontinuous groove.
Further, key device also comprises: several keycaps are arranged on the top of key device, and match with several silica gel push-button contact regions on the silica gel key-press layer; Sheet material is arranged between keycap and the silica gel key-press layer, which is provided with several perforates that match with keycap.
Further, key device also comprises: layers of two-sided, be arranged on silica gel key-press layer below, and bonding with silica gel key-press layer; Thin film switch, be arranged on layers of two-sided below, and bonding with layers of two-sided.
According to a further aspect in the invention, a kind of mobile communication terminal is provided, has comprised the key device of mobile communication terminal of the present invention in this mobile communication terminal.
According to technical scheme of the present invention; Through around the silica gel push-button contact region, being provided with discontinuous groove; Flat sections between the discontinuous groove section is kept key device and is in plateau, has effectively avoided on one side of pressing keys or one jiao the time, in addition on one side or one jiao of problem that warps.
