Keyboard device and key structure thereof

A keyboard device includes a base plate and a key structure. The key structure includes a keycap, a first connecting element, a second connecting element and a stabilizer bar. The first connecting element and the second connecting element are arranged between the base plate and the keycap and connected with the base plate and the keycap. The stabilizer bar is fixed on the first connecting element and the second connecting element. Since the stabilizer bar does not collide with the base plate to generate the unpleasant noise, the keyboard device of the present invention is capable of reducing the noise. Moreover, since the stabilizer bar is fixed on the first connecting element and the second connecting element, it is not necessary to install hooks corresponding to the stabilizer bar on the keycap and the base plate and the fabricating cost is reduced.

The key includes a keycap and a stabilizer bar. The stabilizer bar is connected between the keycap and the base plate. The stabilizer bar includes a main bar part, a first linking part and a first insertion part. The first linking part is connected between the main bar part and the first insertion part. The buffering part is disposed on the base plate or the membrane circuit board and located under the first linking part. While a keycap is moved downwardly relative to the base plate, the linking part of the stabilizer bar is contacted with the buffering part. The contact point between the linking part of the stabilizer bar and the buffering part is used as a fulcrum.

A luminous keyboard includes a key module, a light guide plate, a top-view light-emitting element and a light-shading element. The top-view light-emitting element emits a light beam. The light guide plate is located under the key module. The top-view light-emitting element is located under the light guide plate. A light-outputting surface of the top-view light-emitting element is contacted with the light guide plate. The light-shading element is disposed on the light guide plate for shading the light beam. A portion of the light-shading element is inserted into the light guide plate opening and formed as a reflective part in the light guide plate opening. After the light beam is projected on the reflective part and reflected by the reflective part, the light beam is transferred within the light guide plate and projected to the key module.

Luminous keyboard

A keyboard device includes a key switch, a base plate, a connecting element and a replaceable key. The replaceable key includes a coupling plate and a keycap. The connecting element is connected between the coupling plate and the base plate. The coupling plate includes a first sliding part. The keycap includes a second sliding part. When the second sliding part is slid relative to the first sliding part, the keycap is combined with the coupling plate or the keycap is detached from the coupling plate. Consequently, the keycap is easily assembled or disassembled. Moreover, since the connecting element is not touched during the process of disassembling the keycap, the connecting element is not damaged.

The present invention provides a luminous keyboard, including: at least one key cap; a support plate; a support component, connected to the key cap and the support plate and capable of guiding the key cap to vertically move relative to the support plate; a thin film circuit board, disposed on the support plate; at least one light emitting component, configured to emit a light ray to the key cap; and a shield, covering the light emitting component, where there is a gap between the shield and the light emitting component, and the shield is provided with a diffraction grating at a position where the light ray passes through the shield.

The present invention provides a backlight structure, including: a light source module having a first slant surface, where a slot is provided on the first slant surface, and the slot is configured to accommodate a light emitting element; a light guiding module having a light guiding plate and a light shielding layer, where a second slant surface is provided at a side of the light guiding module; and a baseplate configured to bear the light guiding module and the light source module. The light source module is engaged with the second slant surface of the light guiding module by means of the first slant surface.

Backlight structure

A keyboard device includes a base plate, a connecting element and a keycap. The connecting element is connected with a hook of the keycap and the base plate. The keycap includes an elastic structure, a first hooking part and a second hooking part. The elastic structure hook is installed on an inner surface of the keycap. The first hooking part is arranged beside a first side of the elastic structure. The second hooking part is arranged beside a second side of the elastic structure. While the connecting element is assembled with the keycap, the first hooking part and the second hooking part are pushed by the connecting element and the keycap is bent in response to the elasticity of the elastic structure. Consequently, the first hooking part is moved away from the second hooking part.

The present invention relates to a keyboard, including: a key, a switch circuit board, and a base plate, and the key includes a keycap and a balance bar.

The keyboard includes a membrane circuit board, a key frame, a key, a linking rod and a fixing plate. The linking rod is connected with the key frame. The fixing plate is disposed under the key frame. While the linking rod is rotated relative to the key frame to push the key frame, a position-limiting structure of the key frame is moved along a guiding structure of the fixing plate. Consequently, the key frame is limited to be moved in a first axial direction. Moreover, when the key frame is moved to a locked position at the same level with a keycap of the key, the keycap cannot be pressed down.
