CN2899320Y - Structure of cell-phone key and disk - Google Patents

Abstract

The utility model relates to a design of a new structure of cell-phone key and disk, comprising a disc structural key, wherein, a charge transfer induction slide which educes electrical signal through an induction slide line-out, is arranged in the composite materials layer under the keycap of the disc structural key. The composite materials layer is a composite bed of thermoplastic polyurethane film and silicone rubber layer, with the charge transfer induction slide being arranged between them. The new cell phone keypad and the disc structure, with the combination between the charge transfer induction slide and the existing disc structure of phone keypad, uses charge transfer induction technology to make a sliding disc in key regional. When a finger moves around the disc circumference, control from software makes address book or repertoire rolling. Therefore, quick information choice is accomplished using induction tablet while the key is being pressed. Such a structure can not only be applied to the cell phone key, but also can be applied to other electronic products.

Description

A kind of new mobile phone key and disc structure

Technical field

The utility model relates to a kind of key switch, particularly a kind of new mobile phone key and disc structure.

Background technology

At present, this structure below common employing the in cell phone keyboard: the Lower Half of button adopts 12 buttons of nine palace lattice, and the first half then is about a disk defines, and left and right sides four direction key is cooperating several function keys around the disk.Need constantly press directionkeys in address list and seek when needs are sought the dialing object, selected songs use very trouble too in having the MP3 functional mobile phone.This structure as shown in Figure 1 and Figure 2, adopt the composite material 2 that is composited by thermoplastic polyurethane's (being called for short TPU) sheet 21 and silastic-layer 22 that each keycap 1 is linked together mobile phone key keycap 1 time, thereby and the power on the keycap passed to the action that metal clips 3 is finished switch.

In the prior art, other has a kind of soft-touch control, and it is to utilize electric charge to shift induction technology, the design by electric charge being shifted induction point and integratedly accomplish the amount of increase and decrease control continuously.

Summary of the invention

The purpose of this utility model is to provide a kind of can do a kind of new mobile phone key and the disc structure that quick data is selected for the deficiency that solves above-mentioned technology when being used as button.

In order to achieve the above object, a kind of new mobile phone key and disc structure that the utility model is designed, it comprises the disc structure key, be provided with electric charge in the composite layer under the button keycap of disc structure key and shift sensing chip, electric charge shifts sensing chip and draws the signal of telecommunication by the sensing chip lead-out wire.Described composite layer is that thermoplastic polyurethane's sheet and silastic-layer are compound, and electric charge shifts sensing chip and can be arranged between thermoplastic polyurethane's sheet and the silastic-layer.

Resulting a kind of new mobile phone key of the utility model and disc structure utilize electric charge transfer induction technology that electric charge is shifted sensing chip and combine with existing mobile phone key disc structure, are one in appearance.But utilize electric charge to shift induction technology and can make a sliding disc in the key area.When finger is being done when disk circumference is moved, the control of software can make address list or song form and roll, and makes selecting its this structure as utilizing sensing chip to do quick data in the button, except that being applied on the button of mobile phone, can also be applied on other electronic products.
