The invention provides an armrest movement mechanism and an automobile. The armrest movement mechanism comprises an armrest and a driving mechanism, a hinge structure; and a positioning shaft; the hinge structure comprises a shell, a guide piece, a fixing disc, a ratchet wheel, a pawl and an elastic unit. The shell is fixed with the handrail; the guiding piece, the fixing disc, the ratchet wheel, the pawl and the elastic unit are all arranged in the shell. The fixing disc is fixed to the positioning shaft, the pawl is hinged to the fixing disc, and the ratchet wheel is fixed to the shell. A first tooth part is arranged on the pawl, and a second tooth part matched with the pawl is arranged on the ratchet wheel; a positioning column is arranged on the pawl, a guide groove is formed in the guide piece, and the guide groove is provided with a first position, a second position and a third position; the elastic unit applies force to the positioning column, so that when the positioning column of the pawl is located at the third position, the elastic unit provides force for the pawl to push against the ratchet wheel.
