摘要： This application provides a keyboard assembly, including a keyboard substrate, a plurality of keycaps, and a plurality of lifting supports, where each keycap is connected to the keyboard substrate by using a lifting support; the keyboard substrate is connected to a bottom plate and a top plate; the bottom plate includes a key accommodation groove including a concave slope; the lifting support is located in the key accommodation groove; one end of the lifting support abuts against the concave slope and is capable of sliding on the concave slope; and in a process in which the top plate rotates to a first specified location, the keyboard substrate is driven to move, so that the lifting support slides in a first direction on the concave slope, the lifting support descends, and the keycap descends; and in a process in which the top plate rotates to a second specified location, the keyboard substrate is driven to move, so that the lifting support slides in a second direction on the concave slope, the lifting support ascends, the keycap ascends, and a key travel distance is increased. This application further relates to a device framework and an electronic device. The keyboard assembly provided in this application has a thin shape, a long key travel distance, a simple overall structure, and low manufacturing costs.

摘要： This application provides an electronic device, a keyboard, and an electronic device assembly. The electronic device includes a display and a processor assembly. The processor assembly includes a circuit board and a keyboard. The display is in connection with the keyboard through the circuit board. The keyboard includes a base plate and keys disposed on the base plate. The base plate includes a back support plate, a membrane, and a backlight plate. The membrane and the backlight plate are disposed on two sides of the back support plate. The back support plate supports the membrane, the backlight plate, and the keys. In addition, a buffer structure is disposed on a surface of a side that is of the backlight plate and that faces the key. The back support plate is provided with a first through hole. The membrane is provided with a second through hole. The key is disposed on a side that is of the membrane and that is away from the back support plate. A protrusion is disposed on a side that is of the key and that faces the base plate. The key moves toward the base plate. The protrusion can press the buffer structure. For the keyboard, when the key is pressed, the protrusion comes into contact with the buffer structure, so that the buffer structure buffers the key, and a user feels less fatigue when tapping the keyboard.
