Embodiment
Hereinafter with reference to relevant drawings, key board unit and the button of the utility model one embodiment is described, wherein identical element is illustrated with identical reference marks.
Please refer to Fig. 1, Fig. 2 A to Fig. 2 B, Fig. 1 is the schematic diagram of a kind of key board unit according to the utility model one embodiment.Fig. 2 A is the cutaway view of button 11 along hatching AA ' of Fig. 1.Fig. 2 B is schematic diagram when button 11 shown in Fig. 2 A is pressed.
Key board unit 1 of the present utility model comprises multiple button 11, base plate 12 and conductive film 13.Conductive film 13 is arranged on base plate 12, and multiple button 11 correspondences are configured in the top of conductive film 13.Conductive film has multiple toggle area (not shown), and it corresponds to multiple button 11, when button 11 is pressed, can contact conducting, to transmit push button signalling with the toggle area of corresponding conductive film 13.
Button 11 comprises keycap 111, first strutting piece 112, second strutting piece 113 and electric conductor 114.Electric conductor 114 is arranged on the bottom surface of keycap 111.Base plate 12 comprises the first fixed part 121 and the second fixed part 122.The primary importance 111A of keycap 111 and second place 111B is respectively arranged with water droplet pore structure and sliding groove structure.In the present embodiment, the first fixed part 121 and the second fixed part 122 are respectively axis hole.
First strutting piece 112 comprises the first support portion 112A and the second support portion 112B.One end of first support portion 112A is connected to base plate 12.Second support portion 112B stretches out from the other end of the first support portion 112A, second support portion 112B is connected with the water droplet pore structure of the primary importance 111A of keycap 111, that is one end of the second support portion 112B is fastened in the primary importance 111A of keycap 111 (water droplet pore structure).In addition, one end of the first support portion 112A is then connected with the first fixed part 121 of base plate 12, that is one end and first fixed part 121 (axis hole) of the first support portion 112A are articulated.
One end of second strutting piece 113 is connected to the second fixed part 122 of base plate 12, that is one end of the second strutting piece 113 and the second fixed part 122 (axis hole) are articulated.Due to, in the present embodiment, the second place 111B of keycap 111 is sliding groove structure, and therefore, the other end of the second strutting piece 113 is connected to the second place 111B (sliding groove structure) of keycap 111 in movable mode.In other embodiments, the second place 111B of keycap 111 can be the axis hole of the comparatively wide length in aperture, provides the other end of tolerable second strutting piece 113 to carry out the space of small distance displacement.
In the present embodiment, the first fixed part 121 and the second fixed part 122 are axis hole, instead of known coupler construction.That is, one end of the first strutting piece 112 with and the second strutting piece 113 when assemble, its assembling process can complete easily, assists to assemble without the need to using the instrument of too complex.In addition, the material of the first strutting piece 112 and the second strutting piece 113 can be plastics, rubber or other macromolecular materials.What therefore material cost can be more next than the scissor serial verb construction of metal material in background technology is low.
As shown in Figure 2 B, when button 11 is biased F pressing, because the two ends of the first strutting piece 112 are connected with base plate 12 with keycap 111 respectively, second strutting piece 113 can do the displacement of small distance in the second place 111B of keycap 111 (sliding groove structure), that is, second strutting piece 113 is considered as fulcrum with the junction (the second fixed part) of the second fixed part 122 of the second strutting piece 113 and base plate 12, therefore second strutting piece 113 can produce low-angle wobble, and displacement is carried out in the second place 111B (sliding groove structure) of keycap 111, tilt to move down to make the corresponding second place of keycap 111.
Because electric conductor 114 is arranged at the bottom surface of keycap 111, when button 11 is pressed, electric conductor 114 can be corresponding be pressed button 11 the toggle area of conductive film 13 contact conducting, make signal transacting (not shown) to transmit push button signalling to backend electronics element.In addition, electric conductor 114 is arranged at the position of keycap 111 bottom surface, can be the center of keycap or other positions off-centered, not be restricted in the utility model, can adjust according to product actual design.
In the present embodiment, electric conductor 114 is elastic component, and when button 11 is biased F pressing, electric conductor 114 can contact conductive film 13, and generation deformation quantity, in addition, the first strutting piece 112 is fixed due to two ends, therefore also can produce a little deformation quantity because of force F, thus, when the F that exerts a force is removed, electric conductor 114 can provide restoring force jointly with the first strutting piece 112, makes button 11 recover position originally.
As shown in Figure 2 A, the first support portion 112A of the first strutting piece 112 and the angle theta of the second support portion 112B are obtuse angle, that is the first support portion 112A of the first strutting piece 112 and the angle theta of the second support portion 112B are greater than 90 degree and are less than 180 degree.
Please refer to Fig. 3, Fig. 3 is the schematic diagram of another embodiment of button 11 shown in Fig. 2 A.The structure of the button 11 of Fig. 3 is close with button 11 structure of Fig. 2 A, main difference part is: in the present embodiment, first support portion 112A of the first strutting piece 112 and the angle theta of the second support portion 112B are acute angle, that is the first support portion 112A of the first strutting piece 112 and the angle theta of the second support portion 112B are less than 90 degree.
Please refer to Fig. 4 A to Fig. 4 D, Fig. 4 A to Fig. 4 D is the assembling flow path figure of the key board unit according to the utility model one embodiment.
As shown in Figure 4 A, first conductive film 13 is arranged on base plate 12.Afterwards as shown in Figure 4 B, the first strutting piece 112 is connected with the second fixed part 122 with the first fixed part 121 of base plate 12 respectively with the second strutting piece 113.Afterwards, then as shown in Figure 4 C, by keycap 111 and electric conductor 114 with extra quality injection technique injection molding.Finally, as shown in Figure 4 D, keycap 111 and electric conductor 114 and the first strutting piece 112 and the second strutting piece 113 are assembled, the first strutting piece 112 is connected with the sliding groove structure of second place 111B with the water droplet pore structure of keycap 111 primary importance 111A respectively with the second strutting piece 113.
Because keycap 111, first strutting piece 112 of the present utility model and the second strutting piece 113 are all the simple parts of structure, again because assembling easily, all can effectively reduce in material cost, process costs.
In sum, key board unit of the present utility model and button, because composed component is less, and structure is simple, and compared to known with the button of scissor serial verb construction, except can reducing costs, it is more convenient to assemble.In addition, button thickness can adjust fast according to product demand.
Although the utility model with embodiment openly as above; so itself and be not used to limit the present invention, any those skilled in the art, not departing from spirit and scope of the present utility model; when doing a little change and retouching, therefore protection range of the present utility model is as the criterion when defining depending on claims.
