Embodiment
Referring to Fig. 3, its be key board unit of the present invention in the structure top view of a preferred embodiment.Key board unit 2 includes
Keyboard base 21, multiple press-key structures 22 and the key switch 23 of multiple press-key structures 22 is corresponded to respectively (in order to more clear
Illustrate to Chu, single key switch as shown by dashed lines is only shown in Fig. 3 23), keyboard base 21 carries multiple press-key structures 22
With multiple key switches 23, and multiple press-key structures 22 on keyboard base 21 are arranged to correspond on keyboard base 21
Lower movement；Wherein, move down and support the corresponding button being disposed below when any press-key structure 22 is touched and open
When closing 23, key switch 23 can produce output key signal and give electronic installation (not shown, such as electricity being connected with key board unit 2
Brain), with so that drive electronics perform corresponding instruction.
Fig. 4 and Fig. 5 are referred to, Fig. 4 is the structural representation by bond of key board unit shown in Fig. 3, and Fig. 5 is shown in Fig. 4
The perspective exploded view of press-key structure.Press-key structure 22 includes keycap 221 and multiple graphical pieces 222, and keycap 221 be by
First material is formed, and is had and extended downwardly by the upper surface of keycap 221 and correspond respectively to the multiple of multiple graphical pieces 222
Groove 2211, and multiple graphical pieces 222 are then formed by the second material, and a part for each graphical piece 222 is filled in relatively
In the groove 2211 answered, another part of each graphical piece 222 is then exposed to outside corresponding groove 2211 for pressing.Supplement
Illustrate, in order to more clearly illustrate, Fig. 3 only shows the graphical piece 222 on single push-button structure 22, and enters one with Fig. 4
Walk explanation.
Wherein, the shape of each graphical piece 222 can be font face or geometry, be primarily used to indicate press-key structure
22；For Fig. 4, multiple graphical pieces 222 are to be combined into windows marks, are so as to press-key structure 22 shown in sign picture 4
Windows indicates key.And because multiple graphical pieces 222 are partly to protrude from outside groove 2211 and provide three-dimensional present to feel, therefore
User press-key structure 22 can be identified by pressing the feel of multiple graphical pieces 222 when operation.
Furthermore in this preferred embodiment, it is different from being used for making graphical piece for manufacturing the first material of keycap 221
222 the second material, the ability for carrying out key range structure 22 via graphical piece 222 is pressed so as to lifting user；Wherein, first
Material can be makrolon (PC) material or ABS (Acrylonitrile Butadiene Styrene) material, and the second material
Can be polyvinyl chloride (PVC) material or silica resin (Polysiloxanes) material.And embodiment is above are only, this area skill
Art personnel can be according to practical application request and using appropriate material come keycap 221 and graphical piece 222.
Referring to Fig. 6, its preferred approach flow chart for the manufacture method of press-key structure of the present invention.Press-key structure 22
Manufacture method comprises the following steps：Step S1, the keycap 221 with groove 2211 is formed to project technique；Step S2, to drip glue
Technique forms graphical piece 222 at groove 2211, and at least part graphical piece 222 is outside groove 2211.Wherein, glue work is dripped
Skill is also known as micro injection technique, and the second material is mainly injected to keycap by it by compressed air from syringe (not shown)
On 221, then by heat treatment its solidification is set to turn into graphical piece 222；Therefore, the use of the second material should select it in liquid
The material of more flowability, could more favourable graphical piece 222 manufacture.And the embodiment for being related to drip adhesive process is this
Art personnel are known, therefore are no longer repeated herein.
In addition, in adhesive process is dripped, syringe is first to be moved by machine and again inject the second material after accurately positioning
To keycap 221, therefore, when machine repeatedly moves syringe in response to the shape of graphical piece 222 and completes to inject the second material
Operation after, the ability preliminarily forming of graphical piece 222 and and then can be heat-treated and solidify.And illustrate, present invention design
It is in the reason for formation groove 2211 on keycap 221, the second material is fixed in groove after being injected to keycap 221
Dissipated in 2211 without overflowing, namely being injected to the second material after keycap 221 is filled in groove 2211, therefore in this hair
In bright, the shape of groove 2211 is to correspond to the shape of graphical piece 222 and be designed.
Preferably, but be not limited, key board unit 2 shown in Fig. 3 is the key board unit 2 for including light-emitting component 24, and
Light-emitting component 24 is arranged in keyboard base 21 and to provide light beam, and is then adopted for making the second material of graphical piece 222
Presented with light-transmitting materials, and at the groove 2211 of keycap 221 transparent, therefore the light beam that light-emitting component 24 is provided can be via button
Graphical piece 222 in structure 22 and outwards export, wherein, the light transmittance of light-transmitting materials is determined according to practical application request.
Furthermore in this preferred embodiment, multiple graphical pieces 222 of press-key structure 22 shown in Fig. 4 are respectively by with not
Manufactured by the second material of color, namely in dripping in adhesive process, machine is to drive syringe by second with different colours
Material is injected separately into different groove 2211a~2211d, therefore the light beam provided when light-emitting component 24 is respectively by multiple
Graphical piece 222a~222d and after outwards exporting, a kind of colorful pattern can be outwards presented in the keycap 221 of press-key structure 22
Windows indicates, allows user more to recognize the position of windows mark keys with eyes in the use environment of luminance shortage whereby
Put.
According to more than explanation it can be seen from, press-key structure of the present invention because can be lifted with relief graphical piece user with
The ability of operating handle key range structure, and can when applied to illuminated keyboard auxiliary light emission keyboard produce output it is colorful
Light beam lift the visual identity of user, therefore great industrial utilization.Although in addition, in the above-described embodiments, button
Structure is to be used in key board unit, but those skilled in the art can be according to the enlightenment that above-described embodiment is obtained, and this is sent out
Bright press-key structure be applied to other it is various be used as control purposes electronic installation in, such as remote control, automobile-used control panel.
The foregoing is only presently preferred embodiments of the present invention, be not limited to protection scope of the present invention, thus it is all its
It is intended to be limited solely by protection scope of the present invention without departing from the lower equivalent change or modification completed of spirit disclosed in this invention
It is interior.
