Description

A kind of fingerprint button patch

Technical field

It the utility model is related to electronic product and derive accessory technical field, especially a kind of fingerprint button patch.

Background technology

With the development of science and technology and the improvement of people's living standards, such as smart mobile phone, tablet personal computer, electronics are read Read the necessity that the electronic products such as device are increasingly becoming in people's daily life and work.For the facility for improving electronic product operation The needs of property and the security used, mobile phone that existing Apple Inc. or Huawei Company are produced, tablet personal computer etc. The HOME keys or single fingerprint unlocking button for being provided with there is fingerprint identification function；The mobile phone produced with Apple Inc. Exemplified by, when making pad pasting protection to mobile phone, diaphragm would generally leave blank in HOME key positions so that the upper table of HOME keys after pad pasting Face is lower than the upper surface of diaphragm, can produce certain height fall because of the difference in thickness of diaphragm between the two, thus HOME key positions are caused easily to invade the impurity such as dust, so as to be caused to the service life of mobile phone and the aesthetic appearance of mobile phone Strong influence.Simultaneously as HOME keys are exposed outside, once scratched, it is easy to HOME keys are influenceed to fingerprint signal Collection effect, or even cause HOME keys to damage.

Utility model content

For above-mentioned the shortcomings of the prior art, the purpose of this utility model is to provide a kind of fingerprint button patch.

To achieve these goals, the utility model adopts the following technical scheme that：

A kind of fingerprint button patch, it includes a conductive layer, an adhered layer being attached on the lower surface of conductive layer, one attached In the release film layer on the lower surface of adhered layer and the key mapping ring being attached on the upper surface of conductive layer.

Preferably, the adhered layer is silica gel material layer or EVA material layer or polythene material layer or polyolefin plastomers Resin bed.

Preferably, a pattern decorative layer is additionally provided between the adhered layer and conductive layer, the pattern decorative layer includes One is attached at PET material layer between adhered layer and conductive layer and one is attached at pattern printed layers on the surface of PET material layer.

Preferably, the axial cross section of the collar extension of the key mapping ring is shaped as a truncated cone-shaped, and the upper collar extension of the key mapping ring Bore be more than lower collar extension bore.

Preferably, the key mapping ring is made up of metal material.

As a result of such scheme, the utility model using key lose money in a business body height can reduce because electronic product attach protect Caused height fall sense after cuticula, the height of key mapping and diaphragm is set to strengthen the outward appearance of electronic product close to concordant to improve Aesthetic feeling and the comfortableness to key mapping operation；Simultaneously as the presence of conductive layer can strengthen the collection effect to finger touch signal Fruit, lift the identification function of electronic product fingerprint；Further, since key patch covers whole key mapping, can effectively act as to key mapping Protecting effect, avoid key mapping from occurring damaging because being scratched or the problems such as hydraulic performance decline；Its is simple and compact for structure, has very Strong practical value and market popularization value.

Brief description of the drawings

Fig. 1 is the cross section structure schematic diagram of the utility model embodiment in a disassembled state.

Embodiment

Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing, but the utility model can be by right It is required that the multitude of different ways for limiting and covering is implemented.

As shown in figure 1, a kind of fingerprint button patch that the present embodiment provides, it includes one and is used to be contacted with finger to rise To capacitance signal conduction conductive layer 1 (its can as the case may be by ito thin film (i.e.：Indium tin oxide semiconductor is transparent Conducting film) be made or by transparent conductive cloth into), one be attached on the lower surface of conductive layer 1 with realize whole key is pasted Adhered layer 2, one in key mapping corresponding to sticking in be attached on the lower surface of adhered layer 2 with when key patch is not used to adhered layer 2 are protected the release film layer 3 of (and key patch can be achieved when in use, after being torn off and attach function) and are attached at conduction Layer 1 upper surface on opponent's fingering row it is spacing and can make up key patch diaphragm between difference in height key mapping ring 4.Thus, (the HOME keys or fingerprint recognition of such as mobile phone are unlocked after by adhered layer 2, key is attached in the corresponding key mapping of electronic product Key), using key lose money in a business body height can reduce because electronic product attach diaphragm after caused by height fall sense, make key mapping with The height of diaphragm is close to concordantly with the aesthetic appearance of raising enhancing electronic product and the comfortableness to key mapping operation；Meanwhile Because the presence of conductive layer 1 can strengthen the collection effect to finger touch signal, the identification function of electronic product fingerprint is lifted；Separately Outside, because key patch covers whole key mapping, the protecting effect to key mapping can be effectively acted as, avoids key mapping because being scratched The problems such as now damage or hydraulic performance decline.

To ensure that key pastes the fastness sticked in key mapping, the adhered layer 2 of the present embodiment can be as the case may be using all Such as silica gel material layer, EVA material layer, polythene material layer or polyolefin plastomers resin bed.

Decorative effect for enhancing key patch to whole electronic product, the especially decorative effect in key mapping region, are pasting Be additionally provided with a pattern decorative layer between layer 2 and conductive layer 1, pattern decorative layer include one be attached at adhered layer 2 and conductive layer 1 it Between PET material layer 5 and one be attached at pattern printed layers 6 on the surface of PET material layer 5.Thus, by being set inside being pasted in key Placing graphic pattern decorative layer can effectively strengthen key and lose money in a business the aesthetic appearance of body or even electronic product.

Key mapping is operated exactly for ease of user, prevents finger from slipping, the collar extension of the key mapping ring 4 of the present embodiment Axial cross section is preferably shaped to truncated cone-shaped, and the bore of the upper collar extension of key mapping ring 4 is more than the bore of lower collar extension.Thus, pass through Structure improvement to key mapping ring 4 can provide a placement space that is abundant and specifying for finger, avoid finger from slipping.Certainly, originally The key mapping ring 4 of embodiment also can be according to the shape using other structural behaviours that there is upper port bore to be more than lower port bore Construction.

As a preferred scheme, the key mapping ring 4 of the present embodiment is made up of metal materials such as copper or alloys.Thus, Resistance to compression, the abrasion resistance of whole key patch can be strengthened.

Preferred embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, Every equivalent structure made using the utility model specification and accompanying drawing content or equivalent flow conversion, or directly or indirectly fortune Used in other related technical areas, similarly it is included in scope of patent protection of the present utility model.
