1. A keyboard assembly, comprising:
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 plurality of keycaps;
wherein, for each keycap of the plurality of keycaps, a keycap is connected to the keyboard substrate by using a lifting support of the plurality of lifting supports corresponding to the keycap;
wherein the keyboard substrate is configured to be connected to a bottom plate and a 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, for each key accommodation groove of the plurality of key accommodation grooves, a 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.
