圖8為本發明一實施例的按鍵的部分元件剖面示意圖。圖9為本發明一實施例的按鍵的部分元件剖面示意圖。在本發明中，當內支撐件142及外支撐件141位於其躺下位置時(即鍵帽110位於最低位置，鍵帽110與底板120之間的距離為最小)，內支撐件142與外支撐件141的遮光擋板1413會重疊，即內支撐件142與外支撐件141局部重疊。在一些實施例中，如圖8及9所示，當內支撐件142及外支撐件141移動至其躺下位置時，內支撐件142的鍵帽連接端1422向下與遮光擋板1413貼靠。舉例來說，如圖8所示，可對內支撐件142的鍵帽連接端1422做厚度縮減的設計，使得內支撐件142的鍵帽連接端1422之底部形成容槽1425，在內支撐件142及外支撐件141移動至其躺下位置之過程中，遮光擋板1413相對內支撐件142的鍵帽連接端1422向上進入容槽1425中，進而與鍵帽連接端1422相貼靠；據此，當內支撐件142與外支撐件141位於其躺下位置時，遮光擋板1413位於容槽1424中。 FIG. 8 is a schematic cross-sectional view of some components of a button according to an embodiment of the present invention. FIG. 9 is a schematic cross-sectional view of some components of a key according to an embodiment of the present invention. In the present invention, when the inner support 142 and the outer support 141 are in their lying down positions (ie, the keycap 110 is at the lowest position, and the distance between the keycap 110 and the bottom plate 120 is the smallest), the inner support 142 and the outer The light shielding baffles 1413 of the support member 141 overlap, that is, the inner support member 142 and the outer support member 141 partially overlap. In some embodiments, as shown in FIGS. 8 and 9 , when the inner support 142 and the outer support 141 move to their lying down positions, the keycap connecting end 1422 of the inner support 142 is downwardly attached to the light shielding baffle 1413 Depend on. For example, as shown in FIG. 8 , the keycap connecting end 1422 of the inner support 142 can be designed to have a reduced thickness, so that a groove 1425 is formed at the bottom of the keycap connecting end 1422 of the inner support 142 . During the process of moving the 142 and the outer support 141 to their lying position, the light-shielding baffle 1413 enters the accommodating groove 1425 upward relative to the key cap connecting end 1422 of the inner support 142, and then abuts against the key cap connecting end 1422; Therefore, when the inner support member 142 and the outer support member 141 are in their lying down positions, the light blocking baffle 1413 is located in the receiving groove 1424 .

在一實施例中，如圖9所示，上述的底板120具有破孔124，且薄膜電路板150具有相應於破孔124的貫孔151，遮光擋板1413向下延伸通過貫孔151進入破孔124中，即遮光擋板1413部分位於破孔124中，但本發明不僅限於此；在一實施例中，如圖8所示，上述的遮光擋板1413整體位於薄膜電路板150以及底板120之上方。此外，為使內支撐件142與外支撐件141的堆疊厚度達到按鍵薄型化的需求，外支撐件141位於躺下位置時，遮光擋板1413與內支撐件142、鍵帽110、底板120至少其中一個平行。 In one embodiment, as shown in FIG. 9 , the above-mentioned bottom plate 120 has a hole 124 , and the thin film circuit board 150 has a through hole 151 corresponding to the hole 124 , and the light-shielding baffle 1413 extends downward through the through hole 151 into the hole 151 In the hole 124, that is, the light-shielding baffle 1413 is partially located in the perforated hole 124, but the present invention is not limited to this; in an embodiment, as shown in FIG. above. In addition, in order to make the stacking thickness of the inner support member 142 and the outer support member 141 meet the requirement of thin keys, when the outer support member 141 is in the lying down position, the light shielding baffle 1413 and the inner support member 142, the key cap 110 and the bottom plate 120 are at least One of them is parallel.

在本發明實施例的按鍵100中，藉由上述遮光擋板1413，鍵帽110位於最高位置以及鍵帽110的靠近與遠離底板120之過程中，發光元件131所發出的光線可被有效遮蔽，從而減少光線從鍵帽110與底板120之間的間隙透出的情況，達到控制按鍵100周圍因漏光產生的光暈表現以及避免使用者在視覺上的不適之效果。 In the key 100 of the embodiment of the present invention, the light emitted by the light-emitting element 131 can be effectively shielded when the key cap 110 is located at the highest position and the key cap 110 is approaching and moving away from the bottom plate 120 by the light shielding baffle 1413. Thereby, the light penetrating from the gap between the keycap 110 and the bottom plate 120 is reduced, so as to control the halo performance around the key 100 due to light leakage and avoid visual discomfort for the user.
