Description

Key cap illuminated illuminated keyboard

The invention relates to an illuminated keyboard for a keycap illumination, in particular to an illuminated keyboard in which a light shielding sheet is superposed on a bearing surface of a pressing member, and the light that is directed to the bearing surface is shielded from light, and only the pressing surface and the connecting surface are projected.

Whether it is a desktop computer or a notebook computer, the keyboard device is the most important command input device in the computer system, and its design focus is more on allowing users to input commands comfortably and accurately. In a low-light environment, a user who is not familiar with the symbol or text configuration on the keycap is faced with the inability to accurately input commands. Therefore, in order to respond to the lack of light, the user can clearly identify the keycap. There are a variety of illuminated keyboards available today, such as the United States, No. 6284988, 6322229, 6199996, 6554442, 6179432, Taiwan Bulletin No. 509955, 465777, 535385, 438035, 570235, 468833, 516671, the above cases Both mention a light-emitting keyboard that uses a built-in illuminating sheet to project a light source, and allows the user to accurately judge the keyboard characters under insufficient light.

However, in the above cases, the key cap, the elastic body and the linkage mechanism are made of a light-transmitting material, or the key cap is designed to be non-transparent, and then the symbol on the key cap is used to transmit light, so that the light-emitting element is made. The whole piece of light is generated, so that the keyboard exhibits a uniform light projection pattern. However, such a light-emitting form may cause users to be troubled in use. In the case of insufficient light, the uniform illumination of the keyboard will result in its overall brightness being too strong, which is unfavorable for the user to view, so that the character symbol on each keycap cannot be clearly recognized, even if only the character symbol emits light or If it is obscured, it will still be difficult to identify due to the light interference caused by the adjacent keycaps. For users who are not familiar with the keyboard symbol configuration, the problem cannot be solved specifically.

To this end, the inventors have proposed a non-uniform light-emitting illuminated keyboard. For example, in the Republic of China No. I230957, a shielding member is disposed between the keycap and the light-emitting element to shield the component from a position of the individual keycaps into a light-transmitting region. The adjacent keycaps are not a non-transparent area under the individual keycaps, thereby forming a non-uniform light projection, thereby solving the problem that the conventional illuminated keyboard causes excessive brightness of the keyboard due to uniform light projection. In addition, today's keyboard structure is more pursuit of thinner and lighter. In addition to changing the thickness of the keyboard structure, there is a thin keyboard with no interlocking mechanism or no elastic body. Therefore, the inventor has been able to construct another luminous keyboard structure. The specific thinning.

The main object of the present invention is to provide an illuminated keyboard having both non-uniform illumination and slimness.

In order to achieve the above object, the present invention provides a keycap illuminated illuminated keyboard, the illuminated keyboard includes a keyboard portion and a light emitting portion, and the keyboard portion includes at least a circuit board having a plurality of keyboard command portions and a plurality of corresponding keyboard command portions. A pressing member for triggering the keyboard command portion is pressed by the user on the circuit board, and each pressing member defines a pressing surface, a bearing surface, and a connecting surface between the pressing surface and the bearing surface. Forming a light source projection interval between the pressing surface and the circuit board; the light emitting portion includes a light emitting unit for providing light to the light source projection interval, and a light shielding sheet including a pressing surface for the pressing member The through hole and the light shielding portion stacked on the bearing surface, the light shielding portion shields the light projected from the light source into the bearing surface, thereby limiting the light of the light source of the light source to the pressing surface and the connecting The light is thrown out.

In an embodiment, the connecting surface between the pressing surface and the bearing surface is a slope or a vertical surface.

In one embodiment, the bearing surface is formed by a connecting arm connected to the bottom edge of the connecting surface of the adjacent pressing member.

In an embodiment, the bearing surface is formed by extending a bottom edge of the connecting surface of the adjacent pressing member horizontally with respect to the pressing surface.

In an embodiment, the pressing surface is further provided with a light transmitting area and a non-light transmitting area. Further, the light transmitting area on the pressing surface is a character symbol.

In an embodiment, the connecting surface can be a light transmissive surface or a non-transparent surface.

In an embodiment, the keyboard portion includes an elastic support body that assists displacement of the pressing members relative to the circuit board.
