Background

The integral forming is a main method for making the structure light and thin and reducing the manufacturing process, and in general light and thin keys, for example, a metal sheet or a plastic sheet is often used as the key main body, which uses the steel-hard material of the material to support the whole key structure but often makes the touch of the key hard and the sealing property with the housing less sufficient.

In general, a key body made of an elastic material such as silicone rubber, polyester plastic, polyether plastic, acryl or photo-curable resin needs to have a certain thickness because the texture of the elastic material is soft, and if the thickness of the made key body is insufficient, the key structure will collapse to cause abnormal depression on the surface of the key, and the inclined wall of the key will not have abnormal resilience resistance before and after sitting and lying, so that the problem of insufficient rigidity of the key without section feeling is caused, and the key structure made of the elastic material is not easy to be thinned.

In view of the above, when a lighter, thinner and more pleasant feel is desired, a thin key is formed by combining a key main body made of a light, thinner and integrally molded elastic material and a key support structure sheet made of a high-rigidity material, and the key support structure sheet made of the high-rigidity material is used to increase the rigidity of the thin key main body made of the elastic material, so that the weight of the key structure can be reduced, the manufacturing process can be reduced, the elastic feeling of the elastic material can be pressed, the high extensibility of the elastic material can be improved, and the coating adhesion and key section feel after assembling other components can be reduced.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention is directed to a thin key, and more particularly, to a key structure, which includes: an integrally formed thin key main body made of an elastic material and a key support structure piece composed of a material of high rigidity are provided under the integrally formed thin key main body made of an elastic material, the aforesaid member is formed by joining and then integrating the integrally formed thin key main body made of an elastic material and the key support structure piece made of a material of high rigidity; the thin type press key is made of silicon rubber, polyester plastic, polyether plastic, acryl or light-cured resin, is made of an integrally formed press key main body made of an elastic material which still has elasticity after being cured after the material is thinned, is connected below the press key main body, is used for solving the problem of insufficient rigidity such as structural soft collapse and no step feeling caused by the thinning of the elastic material, and is made of a plastic sheet, a acryl sheet, a nylon sheet or a metal sheet; and the required high-rigidity material with the required color, shape, light transmission degree and rigidity degree can be respectively selected according to the color, shape, light transmission degree and rigidity degree required by each key body in the thin key body to manufacture the required key supporting structure sheet, so that the thin key has better functionality and finished product effect.

Detailed Description

FIG. 1 is a schematic sectional view of an embodiment, which is implemented as follows: the thin key body 11 is made of silicone rubber, polyester plastic, polyether plastic, acryl or photo-curing resin, which is made of an elastic material having elasticity after curing.

The plastic sheet, the acrylic sheet, the nylon sheet or the metal sheet is made of a material having high rigidity when being in a sheet shape, and is made into a key supporting structure sheet 22 which is connected with the thin key main body 11 made of an elastic material and integrally formed by hot press molding, injection molding, punch molding and laser engraving molding.

Then, the thin key body 11 made of elastic material and the key supporting structure sheet 22 made of high rigidity material are jointed and connected with each other in the following way: the key supporting structure sheet 22 made of high-rigidity material is placed in the mold for forming the thin key body 11 made of elastic material, and then the thin key body 11 made of elastic material is formed by hot press forming, injection forming and photo-curing to complete the bonding of the two; after the key main body 11 made of elastic material and the key supporting structure sheet 22 made of high rigidity material are formed integrally, they are bonded together by adhesive; and the key supporting structure sheet 22 made of high-rigidity material required by each key unit can be selected according to the required color, shape, light transmission degree and rigidity of each key unit in the thin key body 11, and then the key supporting structure sheet is jointed once again, so that the thin key can provide more choices of color, shape, light transmission degree and rigidity degree and the effect of finished products.

Fig. 2 is a schematic diagram of a general non-thin type key in an embodiment when pressed, because the thickness of the key body-non-thin type key 12 made of an elastic material is enough, when the pressed key body-non-thin type key 13 is pressed, because the rigidity of the key structure is enough, no matter the pressed-unfinished key structure k2 or the pressed-unfinished key structure k3 is consistent with the key structure k1 which is not pressed yet, and no key structure collapse is generated; and the push-to-bottom key inclined wall m1 and the push-to-bottom key inclined wall m2 are bent along the normal sitting and lying curvature, so that the normal key section feeling is generated along with the push.

Fig. 3 and 2 are schematic diagrams of pressing without using a key supporting structure sheet and pressing of a general non-thin key in the embodiment, as shown in fig. 3, even though the key structure soft-collapse deformation is not generated on the non-pressed key structure k4 due to the lightness and thinness of the integrally formed thin key main body-non-used key supporting structure sheet 14 made of an elastic material, when the pressed thin key main body-non-used key supporting structure sheet 15 is also generated on the key structure soft-collapse deformation when the key structure k5 is pressed and not reached due to the insufficient structural rigidity of the key, and the key structure soft-collapse deformation is also generated on the key structure k6 when the pressing-reaching is increased with the increase of the pressing degree; while the key inclined wall m3 does not bend with the proper sitting and lying curvature like the key inclined wall m1 of fig. 2 when pressed and not pressed to the bottom, the key inclined wall m4 is completely different from the proper sitting and lying curvature of the key inclined wall m2 of fig. 2 when pressed and pressed to the bottom, and the key section feeling cannot be generated because the normal sitting and lying curvature cannot be generated.

Fig. 4 and 2 are schematic diagrams of pressing with the key support structure sheet and pressing of a general non-thin key in the embodiment, as shown in fig. 4, since the key support structure sheet 22 made of a high-rigidity material is used, it is able to obtain sufficient structural rigidity for the thin key main body-using key support structure sheet 16, so that the pressed thin key main body-using key support structure sheet 17, the key structure k8 at press-not-to-bottom and the key structure k9 at press-to-bottom are consistent with the non-pressed key structure k7 and the key structure k2 and the key structure k3 of fig. 2, and no key structure collapse deformation is generated; moreover, the key inclined wall m5 at the press-bottom position is consistent with the sitting and lying curvature of the key inclined wall m1 in fig. 2 when being bent, and the key inclined wall m6 at the press-bottom position is also consistent with the sitting and lying curvature of the key inclined wall m2 in fig. 2 when being bent, so that the normal key section feeling can be generated along with the press.
