The invention discloses an auto-resetting folding footplate comprising a vehicle body, a footplate assembly, pins and an air spring. A footplate supporting plate is disposed at the rear of the vehicle body. U-blocks are symmetrically arranged on two sides of the footplate supporting plate; each U-block is provided with a first through hole; mounting blocks fitting the U-blocks are symmetrically disposed at the front end of the footplate assembly; each mounting block is provided with a second through hole; the U-blocks and the mounting blocks are connected in a hinged manner through the pins; the footplate assembly can rotate around the pins relative to the footplate supporting plate; a first mounting plate is disposed within the footplate supporting plate; a second mounting plate is disposed at the bottom of the footplate assembly; one end of the air spring is connected with the first mounting late, and the other end of the air spring is connected with the second mounting plate; a rear cover plate is disposed between the air spring and the bottom of the footplate assembly. The auto-resetting folding footplate has the advantages that since the piston rod extends out when the air spring is stressed and automatically resets when the air spring is idle, after a driver leaves the footplate assembly, the footplate assembly can automatically close; labor intensity is reduced.
