This disclosure provides a height-adjusting structure and electronic device for adjusting the height of a foot pad. The height-adjusting structure includes a linkage mechanism for driving the foot pad to rise or fall. The linkage mechanism includes: a gear set for linkage with the hinge shaft of the electronic device; a transmission link, the first end of which is meshed with the gear set, thereby reciprocating linearly along a first direction under the meshing transmission of the gear set; and a foot pad movement component, linked to the second end of the transmission link and the foot pad, configured to reciprocate linearly along a second direction under the drive of the reciprocating
linear motion of the transmission link, thereby synchronously driving the foot pad to rise or fall. When this height-adjusting structure is applied to electronic devices, especially laptops, it can better maintain the overall appearance of the
laptop and effectively solve the motion
interference problem during the opening and closing of the
laptop's display.
