Keyboard assembly, device framework, and electronic device

An electronic device, comprising:

• a screen;
• and
• a device framework;
• wherein the device framework further comprises a top plate, a bottom plate, and a keyboard assembly;
• wherein the screen is disposed on the top plate and faces the keyboard assembly, and connected to the device framework in a wired manner or a wireless manner;
• wherein the keyboard assembly comprises a keyboard substrate, a keycap array comprising a plurality of keycaps, and a lifting support array comprising a plurality of lifting supports that are one-to-one corresponding to the keycaps, wherein, for each keycap of the plurality of keycaps, a keycap is connected to the keyboard substrate by using a lifting support corresponding to the keycap;
• wherein the keyboard substrate is configured to be connected to the bottom plate and the top plate;
• wherein the top plate is rotatably connected to the bottom plate;
• wherein the bottom plate comprises a plurality of key accommodation grooves one-to-one corresponding to the plurality of keycaps;
• wherein each key accommodation groove comprises a concave slope;
• wherein the lifting support is located in the key accommodation groove;
• wherein one end of the lifting support abuts against the concave slope and is capable of sliding on the concave slope;
• wherein in a process in which the top plate rotates to a first location relative to the bottom plate, the top plate drives the keyboard substrate to move relative to the bottom plate, so that each lifting support slides in a first direction on the concave slope, and each lifting support descends, to drive each keycap to descend;
• wherein in a process in which the top plate rotates to a second location relative to the bottom plate, the top plate drives the keyboard substrate to move relative to the bottom plate, so that each lifting support slides in a second direction on the concave slope, and each lifting support ascends, to drive each keycap to ascend, thereby increasing a key travel distance of the keycap;
• and
• wherein a direction in which the top plate rotates to the first location is opposite to a direction in which the top plate rotates to the second location.

A device framework, comprising:

• wherein the keyboard substrate is configured to be connected to the bottom plate and the top plate;
• wherein the top plate is rotatably connected to the bottom plate;
• wherein the bottom plate comprises a plurality of key accommodation grooves that are one-to-one corresponding to the plurality of keycaps;
• wherein each key accommodation groove comprises a concave slope;
• wherein the lifting support is located in the key accommodation groove;
• wherein one end of the lifting support abuts against the concave slope and is capable of sliding on the concave slope;

• and
• wherein a direction in which the top plate rotates to the first location is opposite to a direction in which the top plate rotates to the second location.
