A hemming structure and a vehicle. The hemming structure comprises a main body (100), an accessory piece (200) and a movable piece (300). The main body (100) is internally provided with a clamping cavity (101). The main body (100) is provided with a first assembling hole (102) in communication with the clamping cavity (101). The accessory piece (200) is provided with a fastener (210). The outer side of the fastener (210) is provided with a limiting protrusion (220). When the fastener (210) is being pressed, the limiting protrusion (220) can pass through the first assembling hole (102). When the limiting protrusion (220) enters the clamping cavity (101) from the first assembling hole (102), the fastener (210) changes from a pressed state to a recovered state. The limiting protrusion (220) abuts against the inner wall of the clamping cavity (101). The active piece (300) is provided on the side of the main body (100) away from the accessory piece (200). The active piece (300) is movably matched with the main body (100) and at least partially extends into the clamping cavity (101). The active piece (300) can move relative to the main body (100) and presses the fastener (210), so that the fastener (210) changes from a recovered state to a pressed state.
