Introduce the assembling process of button of the present invention below earlier.Shown in Fig. 2 A to Fig. 2 E, shown the basic structure and the assembling process of button of the present invention.

Shown in Fig. 2 A; The substrate 2 of aluminum stamps out four pairs of inverted L shapes, first connecting portion 21; These four pairs of the first pontes are not positioned on the virtual foursquare side and contiguous four corners; Each first connecting portion 21 has hook part 210, forms the opening towards the outside, the distribution that meets at right angles of first connecting portion 21 of phase adjacency pair.One film circuit board 3 is arranged on the top of substrate 2, and its correspondence is the opening shape at first connecting portion, 21 places, passes to hold first connecting portion 21.The sheathed hook part of going into first connecting portion 21 of the following axostylus axostyle 4 of a quadrate shape is 210 times then; Four side 41 sizes of this time axostylus axostyle 4 are less a little than the virtual foursquare size that first connecting portion forms; Following axostylus axostyle 4 be positioned at the circular arc guiding face of hook part 210 upper surfaces that slip over first connecting portion under the effect of external force hook part 210 below, thereby upwards broken away from by hook part 210 restrictions.Following axostylus axostyle 4 is the square ring-type structure of circular cross section.

Shown in Fig. 2 B, a connection piece 1a is assembled in down a wherein side 41 of axostylus axostyle 4.At first connector 1a is aimed at the gap 13 (like Fig. 1) between first, second bent sheet of connector from the following inboard of axostylus axostyle 4, use external force outwards to promote connector 1a then, make that axostylus axostyle 4 gets in the sliding tray 112 of connectors down.When design, can the size in gap 13 be slightly less than down the cross section of axostylus axostyle 4, can prevent down that axostylus axostyle 4 breaks away from from sliding tray 112.Certainly, the weight of the rotation section 12 of the connector 1 of present embodiment is bigger, and generation own can produce the moment to inner rotary, also can prevent down that axostylus axostyle 4 breaks away from (clearly visible like Fig. 4) from sliding tray.

Shown in Fig. 2 C, a foursquare upper shaft lever 5 is set in the rotation section 12 of connector.The size of the following axostylus axostyle 4 of the size of upper shaft lever 5 is big.At first with a side of upper shaft lever 5 in the outside is pressed into four rotation slots 122 of above-mentioned connector 1a, be placed on down the top of axostylus axostyle 4 then to opposite spin and with upper shaft lever 5.

Shown in Fig. 2 D, other three connector 1b, 1c, 1d are assembled in order on other three limits of upper and lower axostylus axostyle.Can connector be placed down the interior side-lower of axostylus axostyle 4, will descend axostylus axostyle 4 to be set in the sliding tray 112 thereby outwards move then, be moved upwards up to upper shaft lever 5 places, outwards pushing is set in rotation slot 122 on the upper shaft lever, then accomplishes assembling.

Shown in Fig. 2 E, at last keycap 6 is withheld on upper shaft lever 5, can accomplish the assembling of a button.As shown in Figure 3; The inner bottom surface of keycap 6 is provided with eight pairs second connecting portions 61; Second connecting portion forms one and catches up with the unidimensional virtual square of axostylus axostyle 5; Foursquare every limit has a pair of second connecting portion 61, and every pair second connecting portion is on this virtual foursquare one side, and second connecting portion is provided with the narrower rotation slot 612 of opening that Open Side Down.Keycap 6 is when upwards axostylus axostyle 5 is withheld, and the rotation slot 612 of second connecting portion is set on the limit that is positioned at the connector outside of upper shaft lever 5.

The motion process that has shown button like Fig. 4 and Fig. 5.When free state (when keycap is not pushed downwards), elastomer (not icon) supports keycap 6 and is positioned at the higher position, and upper shaft lever 5 is accommodated in the rotation section 12 of connector 1, and the sliding tray of sliding part 11 is accommodated down axostylus axostyle 4 and descended axostylus axostyle to be positioned at the bottom of sliding tray.It is outside skewed that connector 1 is the upper end.When keycap 6 is pressed, contract under the elastomer, connector 1 because of skewed and natural by being rotated down clockwise; First connecting portion 21 is a fixed structure; Connector 1 is in the process that is rotated down, and rotate around upper shaft lever 5 rotation section 12, and sliding part 11 is moving inward in following axostylus axostyle 4 rotating process simultaneously slightly; Be in fully with the parallel state of substrate 2 until connector 1, this moment, axostylus axostyle 4 roughly moved to the opening part (but not breaking away from sliding tray) of sliding tray 112 down.The base portion 10 of connector roughly is pressed on the inner bottom surface of keycap 6, and the opening surface of rotation slot 122 is to substrate 2, and the opening level of sliding tray 112 outwardly.The size system that the diaxon bar forms is fixing, and two axostylus axostyles distance systems in the horizontal direction is fixing, and promptly Fig. 4 indicated apart from a.When upper shaft lever 5 pressed down, the distance under its side is followed between the side frame of axostylus axostyle 4 correspondences was certain, so connector 1 need move inward, to guarantee the distance between two axostylus axostyles, following axostylus axostyle 4 is then limited by the hook part 210 of first connecting portion all the time.

Can know from above-mentioned actuation of keys principle; The major function system of upper and lower axostylus axostyle is used for connector 1 is connected keycap 6 and substrate 2; In the process that keycap 6 is pushed downwards, connector 1 is with respect to upper and lower axostylus axostyle rotation and mobile, and relative keycap of upper and lower axostylus axostyle itself or substrate are also without spin.So derive another execution mode: shown in Fig. 2 A; Axostylus axostyle 4 changes into directly and being formed by first connecting portion under will being processed by metallic rod; Following down such as first connecting portion, axostylus axostyle is gone out by injection molded at aluminum base plate; Perhaps first connecting portion directly goes out by the substrate of plastics forming is one-body molded with following axostylus axostyle, guarantees that promptly axostylus axostyle gets final product with substrate is parallel down; In like manner, as shown in Figure 3, axostylus axostyle 5 changes into and is formed directly into the keycap inner bottom surface on will being processed by metallic rod, generally speaking, when keycap is parallel to substrate, also needs upper shaft lever to be parallel to the inner bottom surface of keycap, also guarantees that the relative substrate of keycap moves both vertically.Substrate of the present invention is not limited to above-mentioned execution mode, can do other variation, when being formed with first connecting portion on the LGP sometimes, and this LGP that is so-called substrate.
