To make to have further understanding to the purpose of the present invention, construction, feature and its function, hereby cooperate embodiment detailed
It is described as follows.
Fig. 1 and Fig. 2 is please referred to, Fig. 1 is the stereoscopic schematic diagram according to keyboard 10 provided by one of present invention embodiment,
The keyboard 10 that Fig. 2 is Fig. 1 is along the section schematic diagram of hatching A-A.Keyboard 10 includes bottom plate 12, multiple keys 14, keyboard frame
Frame 16, flexible mask 18 and cementing layer 20, multiple keys 14 are set on bottom plate 12 for user's pressing and execute use
The family function to be inputted.It should be noted that keyboard 10 can preferably apply it is general have be made of upper cover and lower case
(such as laptop or foldable keyboard device) executes use for user's pressing on the portable electronic devices of open-and-close mechanism
The family function to be inputted, but not limited to this.Each key 14 includes keycap 22 and lifting device 24, and lifting device 24 is set
It is placed between bottom plate 12 and keycap 22 and can preferably be designed using the common scissor supporting mechanism applied on keyboard
(but being not limited, other common key lifting supported designs, such as magnetic button design also can be used), whereby, keycap 22
It can be moved up and down via lifting device 24 relative to bottom plate 12.
It is carried out in detail below for the connection process of key 14 and keyboard frame 16, flexible mask 18 and cementing layer 20
Thin description, please refers to Fig. 2, Fig. 3 and Fig. 4, and Fig. 3 is the button cap structure manufacturing method that is proposed according to the embodiment of the present invention
Flow chart, Fig. 4 be arrange in pairs or groups Fig. 3 processing procedure schematic diagram.Firstly, executing step 300, provides and be formed with multiple perforation structures 26
Keyboard frame 16, and keyboard frame 16 and multiple keycaps 22 (only showing it in Fig. 4 with two) are set in lower mold 11
(shown in such as Fig. 4 (a)), so that each keycap 22 is located on corresponding perforation structure 26, wherein as shown in Fig. 2, each keycap
The peritreme supporting surface 30 of 22 top surface 28 and perforation structure 26 is tied at a distance of vertical interval V, the side 32 of each keycap 22 and perforation
The wall surface of the hole 34 of structure 26 is at a distance of horizontal space H.
Then, step 302 is executed, cementing layer 20 is coated on the bottom surface 36 that flexible mask 18 faces multiple keycaps 22
On, and the flexible mask 18 for having been coated with cementing layer 20 is set to (such as Fig. 4 (b) between upper mold 13 and lower mold 11
It is shown).After completing the procedure, step 304 is executed, using 13 pairs of upper mold flexible masks 18 and is set to lower mold 11
In keyboard frame 16 and multiple keycaps 22 carry out it is hot-forming, on flexible mask 18 moulding go out corresponding each keycap
22 protrusion overlay structure 38, and cementing layer 20 is made to fit in the peritreme supporting surface 30 and each key of each perforation structure 26
Cap 22 (shown in such as Fig. 4 (c)), and then flexible mask 18 is completed with the connection process of key 14 and keyboard frame 16 so that key

Cementing layer is coated on the top surface that flexible mask faced on the bottom surface of multiple keycap or be coated on each keycap
And on the peritreme supporting surface of each perforation structure；And
Carry out with the keyboard frame and multiple keycap being set in the lower mold that gas is auxiliary to be heated into the pliability mask
Type, on the pliability mask moulding go out the protrusion overlay structure of corresponding each keycap, and the cementing layer is fitted in
The peritreme supporting surface of each perforation structure and each keycap, or the cementing layer is made to fit in being somebody's turn to do for each perforation structure
Between peritreme supporting surface and the pliability mask and fit in the top surface of each keycap and corresponding protrusion overlay structure
Between；
Wherein the pliability mask have a piece body thickness, the piece body thickness be less than the horizontal space and be less than this it is vertical between
Away from；
When the keycap is pressed, the lateral arm portion which corresponds to the horizontal space generates deflection deformation；
When the keycap is released, the lateral arm portion of deflection deformation provides back stretch to drive the keycap to return to original position.
8. button cap structure manufacturing method as claimed in claims 6 or 7, which is characterized in that the horizontal space between 0.4mm extremely
Between 2mm, the vertical interval is between 0.7mm between 3mm, and the piece body thickness is between 0.1mm between 1mm.
9. button cap structure manufacturing method as claimed in claims 6 or 7, which is characterized in that by the keycap by detachable key
Cap combination parent part and keycap fitting bull combine to be formed.
10. button cap structure manufacturing method as claimed in claim 9, which is characterized in that be first respectively completed the keycap combination parent part
The attaching that assembling and the keycap between the lifting device are bonded between bull and the pliability mask is fixed, and then again will
Keycap fitting bull overlapping is attached on the keycap combination parent part so that the keycap is collectively formed.
