Description
本發明有關一種發光鍵盤,尤指一種鍵盤部一體成形以方便組裝的發光鍵盤。The invention relates to an illuminated keyboard, in particular to an illuminated keyboard in which the keyboard portion is integrally formed to facilitate assembly.
目前市面上所見之鍵盤產品,為因應不同消費市場的需求,各家廠商分別推出整合有發光模組以產生照明效果的發光鍵盤,以吸引消費者目光,並以此附加特點增加消費者購買意願。在強調發光功能的同時,業者亦致力於研發可降低鍵盤模組整體厚度之結構設計,使其可廣泛應用於如筆記型電腦或強調輕薄設計的桌上型鍵盤上。At present, the keyboard products seen on the market, in response to the needs of different consumer markets, each manufacturer has launched a luminous keyboard integrated with a lighting module to produce lighting effects, in order to attract consumers' attention, and to increase the consumer's willingness to purchase with this additional feature. . While emphasizing the illuminating function, the company is also working on a structural design that reduces the overall thickness of the keyboard module, making it widely used in notebook computers or desktop keyboards that emphasize thin design.
習用發光鍵盤結構如美國發明專利第US8,319,130、US7,939,773、US6,217,183等專利案所揭,習用發光鍵盤具有一鍵帽、一受該些鍵帽觸發產生指令訊號的電路板、一設置於該電路板一側的基板,以及一兩端分別連接該鍵帽與該基板的連動機構。該發光鍵盤架構中,該鍵帽受力朝該電路板方向位移時,該連動機構受壓迫而向下觸壓該電路板上的一電路開關,令該電路開關導通產生相應的控制訊號,當該鍵帽所受按壓的作用力消失時,該連動機構則提供該鍵帽一回彈力道推頂該鍵帽脫離該電路板而相對該電路板具有一高度。然而,該連動機構始終具有一定的結構厚度,縱使該連動機構受該鍵帽連動而產生壓縮,其仍具有一定的厚度,使該發光鍵盤的薄型化仍然受限於該連動機構而無法進行更進一步的改良。The conventional illuminating keyboard structure is disclosed in US Patent No. 8,319,130, US Pat. No. 7,939,773, and US Pat. No. 6,217,183. The conventional illuminated keyboard has a key cap, a circuit board triggered by the key caps to generate a command signal, and a setting. The substrate on one side of the circuit board and the two ends are respectively connected to the interlocking mechanism of the key cap and the substrate. In the illuminating keyboard structure, when the keycap is displaced in the direction of the circuit board, the linkage mechanism is pressed to touch a circuit switch on the circuit board downward, so that the circuit switch is turned on to generate a corresponding control signal. When the force of pressing the keycap disappears, the linkage mechanism provides the keycap with a resilient force to push the keycap away from the circuit board to have a height relative to the circuit board. However, the linkage mechanism always has a certain structural thickness, and even if the linkage mechanism is compressed by the linkage of the key cap, it still has a certain thickness, so that the thinning of the illuminated keyboard is still limited by the linkage mechanism and cannot be performed. Further improvement.
為克服該連動機構所衍生的問題,亦有廠商提出一鍵盤結構設計,如中華民國第M434979號專利所揭,其是以一第一支撐件及一第二支撐件組合形成一V字型結構,透過該V字型結構的設計解決習用該連動機構X字型結構所帶來的厚度問題。然而M434979號專利雖然可降低該發光鍵盤的厚度,但實質上僅是將該連動機構以另一型態實施於該鍵盤之中,所能產生的薄型化效果仍然有限,且該第一支撐件與該第二支撐件的設置,實際上不利於該鍵盤的組裝,使該鍵盤組裝的步驟增加。In order to overcome the problems caused by the linkage mechanism, some manufacturers have proposed a keyboard structure design. As disclosed in the Patent No. M434979 of the Republic of China, a combination of a first support member and a second support member forms a V-shaped structure. Through the design of the V-shaped structure, the thickness problem caused by the X-shaped structure of the interlocking mechanism is solved. However, although the patent No. M434979 can reduce the thickness of the illuminated keyboard, substantially only the linkage mechanism is implemented in the keyboard in another type, and the thinning effect that can be produced is still limited, and the first support member is still limited. The arrangement with the second support member is actually not conducive to the assembly of the keyboard, and the steps of assembling the keyboard are increased.
