  • Patent number: 11158470
    Abstract: A luminous key comprises a key cap, a bottom plate, a first circuit component and a second circuit component. The key cap comprises a body, an extension part and a light exiting part. The extension part is disposed at the periphery of the body. The light exiting part is disposed on the body. The bottom plate has a through hole. The first circuit component has a first layer, a second layer and a light emitting unit. The first layer is disposed on the second layer. The light emitting unit is disposed between the first layer and the second layer, and the light emitting unit is corresponding to the through hole. The second circuit component is disposed between the key cap and the bottom plate. A lifting structure is disposed between the key cap and the bottom plate. Light adjusting structures define a light adjusting region. An orthographic projection of the light adjusting region towards the second layer covers at least a portion of the light emitting unit.

  • Patent number: 10325735
    Abstract: The invention provides a key support mechanism and a key module. The key support mechanism is adapted to be disposed between a base plate and a keycap and includes two scissor structures and a first connecting member. The two scissor structures include two first support frames and two second support frames respectively pivotally connected to the two first support frames. Each of the first support frames includes a first side and a second side opposite to each other, a first fixing part located on the first side, and a second fixing part located on the second side. Each of the second support frames includes a third side and a fourth side opposite to each other, a third fixing part located on the third side, and a fourth fixing part located on the fourth side. The two first fixing parts and the two third fixing parts are respectively adapted to be fixed to the keycap, and the two second fixing parts and the two fourth fixing parts are respectively adapted to be fixed to the base plate.
