Abstract

The utility model discloses a mobile phone keystroke structure, comprising a mobile phone shell 20, a keystroke group 10 consisting of a plurality of hard plastic keystrokes which are arranged together, and a film 30 which is provided with a plurality of bulges and soft performance; wherein, the mobile phone shell 20 is arranged between the keystroke group 10 and the film 30; the keystroke group 10 is connected with the film 30 by a superglue or a strong double-sided glue; and the mobile phone shell 20 is laminated between the keystroke group 10 and the film 30. According to the keystroke structure, the keystrokes can be simply fixed on the mobile phone shell without designing an additional fixed plate fixed on the shell as the traditional keystroke design which has plenty of limits on the keystroke group design. The structure leads the appearance design effect of the keystroke group to be more flexible and changeable; simultaneously, the structure saves the fixed part compared with the traditional mobile phone keystroke design, thus designing thinner and lighter keystrokes; furthermore, when the film is suitably changed, the film circumference is hermetically bonded on the shell, thus preventing dust and water from entering the keystroke area and increasing the use safety of the mobile phone.

Description

A kind of mobile phone press-key construction

Technical field:

The utility model relates to a kind of mobile phone component, particularly a kind of press-key structure that is used for mobile phone.

Background technology:

Along with development of science and technology, the development of mobile phone is more and more universal, and outward appearance is also come also ultimate attainment more, and the button design style of individual character effect also gets more and more and occupy greatly in mobile phones design.Traditional mobile phone key design is an independently composition,

In the mode that fixing plank arranged or on plastic key, grow the lip limit fix, this design is able to widespread usage because of its ease for use in the regular handset button, but owing to key groups independently will be fixed on the housing, require button and housing border from the teeth outwards that certain distance is arranged, could be on enclosure interior be fixing key groups, appearance and modeling is single, and since after be loaded on housing, dust and sweat are easy to into, cause disabler.

The utility model content:

In order to solve the problems of the technologies described above, the purpose of this utility model provides a kind of simple, easy-to-use novel button project organization.

This mobile phone press-key construction comprises housing, key groups, cushion compound.Wherein, key groups and cushion compound are clipped in the middle housing, adopt glue, double faced adhesive tape or hot melt solid gum that key groups is fixed on the cushion compound convex platform.

Described housing is provided with perforation in the key area, and the convex platform of cushion compound is by passing perforation and adopting glue, double faced adhesive tape or hot melt solid gum that key groups is fixed on the cushion compound convex platform like this.

Described key groups can be to adopt the working of plastics of Shooting Technique (plastics PC ABS PMMA and synthetic plastic thereof), also can be the plastic tab that adopts cross cutting and Sheet Metal Forming Technology.

Described housing can be the working of plastics that adopts Shooting Technique, the steel disc that also can be bumped into by in-mould injection technology in the key area.

The described part of cushion compound beyond pressing partly can being bonded on the housing to reach the effect of sealing.

Described cushion compound adopts silica gel to make.

Above-mentioned press-key structure, in the time of user's pressing keys, because key groups directly is bonded on the cushion compound convex platform, pressure can pass on the boss of weak foot sheet by key groups, pass to following metal DOME (metal bump steel disc) sheet group again and produce the button effect, wherein cushion compound has played and has pushed the metamorphosis that needs and the transfer function of pressing force.

Above-mentioned press-key structure, after key groups and cushion compound are fixed together housing is clipped in the middle, after housing was fixing, the key groups on the surface was fixed together because of large tracts of land and flexible glue, and difficult generation mobile phone falls or other impact the phenomenon that back key groups are deviate from mobile phone shell.Cut because do not need other fixed forms, the key groups of outside can design at any time.No longer include the border and need leave the limitation of fixed in space button.

Description of drawings:

Further specify the utility model below in conjunction with the drawings and specific embodiments.

Fig. 1 is the application decomposing schematic representation of the mobile phone press-key construction among the embodiment.

Fig. 2 is the profile a of the mobile phone press-key construction among the embodiment.

Fig. 3 is the sectional exploded view of the mobile phone press-key construction among the embodiment.

Fig. 4 is the profile b of the mobile phone press-key construction among the embodiment.

Embodiment:

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 1, the press-key structure in the present embodiment comprises

handset shell

20, and 10, one of several duroplasts key arrangement key groups together have the film 30 of several projectioies and softness.Wherein handset shell 20 is between key groups 10 and film 30, and key groups 10 adopts super glue or powerful double faced adhesive tape to link to each other with film 30, and handset shell 20 is clipped in the middle.Its middle shell can be with the duplicate material of housing in the part 21 of button, and when needs were saved thickness, housing also can be a steel disc in the part 21 of button, and thickness 0.2mm is above to get final product, and adopts the in-mould injection processes together.

As shown in Figure 2, handset shell 20 is pressed from both sides 30 in the centre by button 10 and cushion compound, and handset shell 20 and film 30 are to bond together by glue.Below cushion compound 30 DOME that is used for button elastic force and function (a kind of mobile phone key common metal contact flat spring) group 40 and the button electrical property plate of using always 50.

As shown in Figure 3, convex platform 31 and following convex cylindrical 32 are arranged above the cushion compound 30, wherein convex platform 31 is that the hole 22 of passing housing bonds together with key groups.Lower convex platform 31 is boss commonly used in the mobile phone press-key construction, is used for following DOME effect.

As shown in Figure 4, Fig. 4 represents that the another kind of this example uses, when cushion compound 30 as figure when 33 places and housing 20 are fixed together, just can realize that button seals fully, prevent that sweat, dust from entering into mobile phone inside by the slit of key groups 10, damage the mobile phone internal components.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
