Please refer to FIG. 6 to FIG. 8, FIG. 6 is a partial schematic top view of the keyboard holder and key cap, FIG. 7 is a schematic top view of the key cap, and FIG. 8 is a partial top schematic view of the keyboard holder. In this embodiment, in more detail, the length W1 of the keycap 2 between the bottoms of the two outer sloping surfaces 211 is 16.45 mm, the width D4 is 16.25 mm, and the inclined side wall 11 is between the tops of the two inner sloping surfaces 111 The length W2 is 16.55 mm, and the width D1 is 16.35 mm. The gap between the inclined side wall 21 of the entire keycap 2 side and the adjacent inclined side wall 11 is 0.05mm, while the gap between the side wall of the general keycap side and the adjacent side wall is 0.5mm Or greater than 0.5mm design.

Please refer to FIG. 2. In this embodiment, in more detail, when the keycap 2 is pushed down, the keycap 2 is pushed against the rubber dome 4 below. The rubber dome 4 is collapsed to provide tactile feedback of pressing the keycap 2. In addition to providing the desired tactile response, the rubber dome 4 can also suppress keystroke. In addition, the bottom of the keycap 2 is provided with each link mechanism 5, the keycap 2 is pivotally disposed in the accommodating hole 12, and pressing the keycap 2 can trigger the key contacts on the circuit board.

In more detail, the inwardly inclined surface 111 of the inclined side wall 11 has an inwardly inclined angle Ɵ2 (see FIG. 4 ), and the outwardly enlarged inclined surface 211 of the inclined side wall 21 has an outwardly inclined angle Ɵ1. In an embodiment, the outwardly-inclined tilt angle Ɵ1 is greater than or equal to the retracted-inclined tilt angle Ɵ2. The inward tilt angle Ɵ2 is 15 degrees to 20 degrees, preferably 17 degrees or 18 degrees. The external expansion angle Ɵ1 is 20 degrees to 25 degrees, preferably 22 degrees.

Please refer to FIG. 2, FIG. 9 to FIG. 10, FIG. 9 is a schematic diagram of the appearance of the keycap, and FIG. 10 is a schematic diagram of a top view. As a second embodiment of this creation, in this embodiment, the top surface of the keycap 2 is provided with a shielding layer 25, and the inclined side walls 21 of each keycap 2 are made of transparent or translucent materials.

In this embodiment, in more detail, the material of the keycap 2 may be acrylic (Polymethyl methacrylate (PMMA), polycarbonate (Polycarbonate, PC), glass, or the like.

In this embodiment, in more detail, the shielding layer 25 may be formed on the top surface of the keycap 2 by painting, printing, in-mold transfer (IMR) or out-of-mold transfer (OMR) technology.

In this embodiment, in more detail, the shielding layer 25 includes key engravings 251 (key legend) in the shape of hollow patterns, numbers, or characters. The hollow patterns, numbers or characters of the key engraving 251 (key legend) can be formed by the process technology of the laser engraving or micro-hole laser engraving. The inscription 251 (key legend).

In this embodiment, in more detail, the keyboard device 100 may also be a backlit keyboard. The keyboard device 100 includes a plurality of light-emitting elements. The light-emitting part may specifically be a light-emitting body such as an LED lamp, a white woven lamp or a halogen lamp. Each light-emitting element is electrically connected to the conductive circuit on the circuit board to provide power through the conductive circuit to emit light. The light-emitting side of each light-emitting member faces the keycap 2 so that the light transmitted through the inclined side wall 21 of the keycap 2 is evenly distributed and can be seen in a dark environment.

In this embodiment, in more detail, the key inscription 251 on the keycap 2 of the backlit keyboard device 100 and the transparent or translucent portion of the inclined side wall 21 of each keycap 2 are for light transmission. Especially when the top of each keycap 2 protrudes out of each accommodating hole 12 (please refer to FIG. 2 and FIG. 4 at the same time), bright light is emitted around the periphery of each keycap 2. In the dim light, the user can see the edge of the key cap 2. That is to say, in the backlight-type keyboard device 100, the light source can emit divergent light on the inclined side walls 21 of each keycap 2, so that the periphery of each keycap 2 generates a halo effect. In other words, the position of the inclined sidewall 21 and the key inscription 251 of each keycap 2 is not provided with a shielding layer and can transmit light.

Through the design of the trapezoidal key cap 2, it can effectively block the light from passing through the gap between the key cap 2 and the inclined side wall 11 to produce halos and prevent the problem of light leakage from the keyboard.

In summary, when the keyboard device of the present invention provides that the top surface of the keycap protrudes out of the accommodating hole, the bottom of the inclined side wall of the keycap abuts the top of the inclined side wall of the keyboard frame, and the inclined side wall is closely related to the inclined side wall Jointing and no gap, to avoid the problem of fingers easily entering the gap or using foreign objects to extend into the gap. In addition, the inclined side wall and the inclined side wall are tightly joined and have no gaps to prevent water from penetrating into the keyboard frame, resulting in the problem of short circuit of the circuit board circuit.

In the keyboard device of the present invention, when the inclined side walls of each keycap are transparent or translucent, light can be transmitted. When the top surface of the keycap protrudes out of the accommodating hole, the inclined side wall around each keycap provides a halo effect to help the user see the edge of the keycap in dim light. Through the trapezoidal key cap design, it can effectively block light from passing through the gap between the key cap and the inclined side wall to produce halos and prevent the problem of light leakage from the keyboard.

Although this creation is disclosed as above with the foregoing embodiments, it is not intended to limit this creation. Anyone who is familiar with similar techniques can make some changes and retouching without departing from the spirit and scope of this creation. The scope of patent protection shall be determined by the scope of the patent application attached to this specification.
