As shown in FIG. 4, the reinforcing component 12 includes two first reinforcements. Part 120, and a second reinforcing part 121 connected between the two first reinforcing parts 120, and where the second reinforcing part 121 is lower than the touch area 112, the second reinforcing part 121 may be long Those plate-shaped ones extend in two directions along the underside of the supporting plate area 111 so that the two first reinforcing portions 120 are respectively connected to the two ends of the second reinforcing portion 121 and the two first reinforcing portions 120 Those that are roughly in the shape of a rectangular plate are located below the pallet area 111 of the upper cover 11 and are laminated and combined. In the embodiment of the present invention, the two first reinforcing portions 120 may be a fiber material, such as a composite material such as carbon fiber, glass fiber, plastic, or the two first reinforcing portions 120 may be aluminum, magnesium, or Made of metal materials such as alloys. The second reinforcing portion 121 may be a fiber material, for example, a composite material such as carbon fiber, glass fiber, plastic, or the two first reinforcing portions 120 may be a stamped and formed plate made of a metal material such as aluminum, magnesium, or an alloy thereof. The metal stamping plate of the second reinforcing portion 121 forms a concave accommodating space 123 (as shown in FIG. 5) for accommodating the touch panel 4 in the touch area 112, and the concave accommodating space is formed. The depression angle, radian or shape of 123 can be designed according to actual needs, and is not limited to the embodiment shown in the drawings. The two first reinforcing portions 120 are respectively connected to two ends of the second reinforcing portion 121 to form a reinforcing component 12. As shown in part A of FIG. 5, in the embodiment of the present invention, the reinforcing component 12 may be formed integrally. As shown in FIG. 6 or FIG. 7, in one embodiment of the present invention, the above-mentioned first reinforcing portion 120 and second reinforcing portion 121 may be combined with each other in a laminating or overlapping manner, or may be further adhered to each other. Adhesive methods such as adhesives or other fixing methods are used to adhere to each other to increase the strength of the joint surface between the first reinforcing portion 120 and the second reinforcing portion 121 to form the reinforcing component 12. As shown in FIG. 8, in one embodiment of the present invention, the two first reinforcing portions 120 are respectively covered and connected to two ends of the second reinforcing portion 121. As shown in FIG. 9, in one embodiment of the present invention, the two first reinforcing portions 120 and the second reinforcing portion 121 are respectively abutted and combined at two ends.

Please refer to FIG. 3 and FIG. 5 together. In addition to the above-mentioned reinforcing components 12 being bonded under the pallet area 111 by lamination, they can also be adhered with each other by means of adhesion such as an adhesive to increase the The strength of the joint surface between the upper cover 11 and the reinforcing component 12, and the reinforcing component 12 can also be disposed on the lower surface of the pallet area 111 of the upper cover 11 through adhesive or other fixing methods.

In the embodiment of the present invention, the two first reinforcing portions 120 may be respectively provided with one or a plurality of grooves 122, and the grooves 122 may be through holes or through holes, and the supporting plate A corresponding one or a plurality of reinforcing ribs 113 may be provided below the region 111; therefore, when the upper cover 11 and the reinforcing component 12 are assembled and combined, the groove 122 on the two first reinforcing portions 120 will be connected to the lower portion of the supporting plate region 111. The reinforcing ribs 113 are embedded in each other and combined and positioned as an implementation aspect of structural assembly.

As shown in FIG. 1 and FIG. 5, since the touch area 112 of the upper cover 11 is used for the touch panel 4 configuration, and in order not to affect the required thickness space D of the touch panel 4 installation, the second reinforcement The portion 121 has the concave receiving space 123, so that a gap d can be reserved between the touch area 112 and the second reinforcing portion 121 so that the touchpad 4 still has a sufficient thickness space D to enable It is disposed in the touch area 112.

Further, as shown in FIG. 10, in the design of the above-mentioned reinforcing rib 113, the present invention is based on a center point C on the surface of the keyboard 1 or the upper cover 11 as a center, and extends toward the two first reinforcing portions 120, respectively. The outer diffusion or the radial structure extends, or it is preferable that the above-mentioned reinforcing rib 113 is attached to a center point C on the surface of the upper cover 11 as a center and faces the two first reinforcing portions along a diagonal direction of the upper cover surface, respectively. Extending to form the extended form of the reinforcing rib 113; thus, after the upper cover 11 is combined with the reinforcing component 12, the torsional rigidity of the keyboard 1 on the two sides of the touch area 112 can be increased. In addition, of course, the reinforcing ribs 113 can also be extended in the vertical or horizontal direction to increase the bending rigidity, and even the plural reinforcing ribs 113 are in the radial, vertical, or horizontal extending types to meet the requirements. Anti-twist and bending rigidity in all directions.
