Abstract
The invention provides a key assembly, which comprises a key shell, a plurality of key layers, and elastic bodies corresponding to the respective key layers, and further comprises a film, wherein the key shell is ejected and formed on the film, and the elastic bodies are ejected and formed on the film connected with the key shell, so that the key shell and the elastic bodies are fixed through the film. Therefore, a fixing structure is eliminated, the production is more convenient, and the thinning of the key assembly is realized.
Description
[technical field]
The present invention relates to a kind of button assembly, especially refer to a kind of key casing and push the button assembly of elastomer formation in same film.
[background technology]
Along with popularizing of electronic products such as mobile phone, compete violently further, how to design electronic product cheap and that pattern is novel, become the emphasis that each manufacturer is studied.
The various button assembly that is used for each electronic product generally all include button, fixedly button shell and be positioned at the elastomer that the button below provides feel and realizes pressing function, generally be provided with fixed part around the elastomer, be fixed in shell by fixed part, have in the assembling process of button assembly elastic portion is fixed to this step of shell, if can cast out this step, can simplify the assembling process of button assembly.
In view of above disappearance, a kind of button assembly that can address the above problem of ad hoc meter.
[summary of the invention]
The object of the present invention is to provide a kind of easily manufactured button assembly.
For achieving the above object, the present invention adopts following technical scheme: a kind of button assembly, it comprises the elastomer of key casing, plurality of keys layer and corresponding each key layer, wherein this button assembly further comprises a film, the key casing ejection formation is in film, and the elastomer ejection formation is in the film that is connected with key casing then.
Compared with prior art, the present invention has the following advantages: described button assembly comprises a film, the key casing ejection formation is in film, the elastomer ejection formation is in the film that is connected with key casing, make key casing and elastomer fix by film, saved fixed structure, made more convenient and realized the thin typeization of button assembly.

Fig. 1 is the schematic diagram of button assembly of the present invention;
Fig. 2 is the exploded view of button assembly of the present invention;
Fig. 3 is the exploded view at another visual angle of button assembly of the present invention;
Fig. 4 is the profile of button assembly of the present invention.
[embodiment]
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
See also Fig. 1 to shown in Figure 4, button assembly 100 of the present invention comprises the plurality of elastic body 3 of key casing 1, plurality of keys layer 2, corresponding each key layer and is used to connect key casing and elastomeric film 4.
See also Fig. 2 to shown in Figure 3, this key casing 1 comprises flat part 11 and each kink 12 that extends from each bending back, edge of flat part, and kink 12 is positioned at a side at flat part 11 back sides.This flat part 11 is provided with window 111 and the some through holes 112 that is used to install display panel.
Plurality of elastic body 3 lays respectively in the different through hole 112, does not contact mutually, and the shape of each elastomer 3 is corresponding with the shape of each through hole 112.Each elastomer 3 comprises the projection 32 of main part 31 and autonomous body 31 back side central protrusion, and this projection 32 is cylindrical.Comprise a navigation elastomer 33 as navigation usefulness in the plurality of elastic body 3, this navigation elastomer 33 further has peripheral projection 34 around central protrusion 32 except that having central protrusion 32.
Elastomer 3 front surfaces are given prominence to key casing 1, and plurality of keys layer 2 sticks at the front surface of each elastomer 3 respectively, and key layer 2 is the plane with the contact-making surface of elastomer 3, and wherein a part of key layer is formed as one.The projection 32 of key layer 2 and elastomer 3 is positioned at the not homonymy of elastic body active body 31.
See also shown in Figure 4ly, film 4 is embedded in the flat part 11 of key casing 1 and the main part 31 of elastomer 3, and kink 12 and projection 32 are positioned at the homonymy of film 4.This film 4 reticulates that (drawing of the present invention is only represented with a plane, film surface has densely covered hole in fact), adopt PETG (PET) material to make, key casing 1 ejection formation is in film 4, elastomer 3 ejection formations are in the film 4 that is connected with key casing 1 then, and elastomer 3 is arranged in through hole 112, thereby make key casing 1 and elastomer 3 fix by film 4, saved fixed structure, made more convenient and realized the thin typeization of button assembly.
The above only is an execution mode provided by the invention, it or not whole or unique execution mode, the variation of any equivalence that those of ordinary skills take technical solution of the present invention by reading specification of the present invention is claim of the present invention and contains.
