Description
Technical field
The utility model relates to display technology field, in particular to a kind of key module.
Background technique
Display is also generally referred to as monitor.Display is the I/O equipment for belonging to computer, i.e. input-output equipment.It
It is a kind of show tools that certain electronic document is shown to by specific transmission device and is re-reflected into human eye on screen.Root
According to the difference of manufacture material, cathode-ray tube display (CRT), plasma display PDP, liquid crystal display LCD etc. can be divided into.
With the continuous development of human society, the continuous improvement of economic level, user is more next to the experience requirements of display
Higher, in some industry generic modules, some users require to provide the higher module of integrated level, need integrating keys.
Utility model content
The purpose of the utility model is to provide a kind of key modules, and which solve press in traditional industry generic module without integration
Key, the lower problem of integrated level.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of key module, including be arranged on Liquid Crystal Module pcb board keypad, diaphragm, fitting part, bowl key and
Bracket, the bracket are located at the Liquid Crystal Module back side, and the keypad is fixed on the bracket, and the bowl key is located at
Setting is contacted between the diaphragm and the keypad and with the keypad, the diaphragm is fixed on institute by the fitting part
It states on bracket, PET bump button contact is provided on the diaphragm, PET bump button contact is with the bowl by bonded
Touching.
Using the above structure, it using bowl key, is positioned by band fitting part diaphragm, bowl key-press joint into PCB,
Again by pressing pressuring film plate, bowl key is touched using PET sheet salient point, realizes keypress function.Structure is simple, compact, easy to process,
Improve the integrated level of industrial generic module.
It advanced optimizes are as follows: the diaphragm is PET dough sheet.
Using the above structure, cheap, sense of touch is preferable.
It advanced optimizes are as follows: the fitting part is Double-face adhesive, and is attached to the diaphragm back side on one side, another side and the bracket side
The fitting of portion edge.
It advanced optimizes are as follows: there are cavity between the keypad and the fitting part, the bowl key is contained in institute
It states in cavity, PET bump button contact is protruded to the cavity inside direction and with the bowl by key contacts.
It advanced optimizes are as follows: the PET sheet thickness is 0.012mm-0.25mm.
In conclusion the utility model has the following beneficial effects: being determined using bowl key by band double-sided adhesive diaphragm
Bowl key is touched using PET sheet salient point, realizes key bowl key-press joint into PCB, then through pressing PET dough sheet in position
Function.Structure is simple, compact, easy to process, simple economy, improves the integrated level of industrial generic module.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment, is mainly used for embodying the structure of Liquid Crystal Module；
Fig. 2 is the schematic cross-sectional view of embodiment, is mainly used for embodying the structure of key module.
In figure, 1, Liquid Crystal Module；2, keypad；3, diaphragm；4, fitting part；5, bowl key；6, PET bump button touches
Point；7, bracket；8, cavity.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment: a kind of key module, as shown in Figure 1, 2, including be arranged on Liquid Crystal Module 1PCB plate keypad 2,
Diaphragm 3, fitting part 4, metal bowl key 5 and bracket 7.Bracket 7 is located at 1 back side of Liquid Crystal Module, and keypad 2 is fixed on bracket 7
On, bowl key 5 contacts setting between diaphragm 3 and keypad 2 and with keypad 2.PET sheet thickness is 0.012mm-
0.25mm, and preferably 0.036mm, 0.05mm or 0.125mm.Diaphragm 3 is fixed on bracket 7 by fitting part 4, on diaphragm 3
It is provided with PET bump button contact 6, PET bump button contact 6 is contacted with bowl key 5.Diaphragm 3 is PET dough sheet, fitting part 4
For Double-face adhesive, and it is attached to 3 back side of diaphragm on one side, another side is bonded with 7 side margins of bracket.It is stayed between keypad 2 and fitting part 4
There is cavity 8, bowl key 5 is contained in cavity 8, and PET bump button contact 6 is protruded to 8 internal direction of cavity and pressed with bowl
Key 5 contacts.
Using metal bowl key 5, is positioned, bowl key 5 is fitted in PCB, then pass through by band double-sided adhesive diaphragm 3
PET dough sheet is pressed, bowl key 5 is touched using PET sheet salient point, realizes keypress function.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
