The invention discloses a vehicle, a safety belt and a buckle device of the safety belt. The buckle device comprises a guide rail, a buckle, a locking component, a contact switch, a button and a bidirectional coil spring. The buckle is disposed on the guide rail in a manner of moving up and down and fits a tongue of the safety belt. The locking component is disposed on the guide rail and can move between a locking position and a contact position. When at the locking position, the locking component allows the buckle to be locked to the guide rail; when at the contact position, the locking component allows the buckle to move up and down along the guide rail. One end of the contact switch is connected with the buckle, and the other end thereof is connected with the locking component. The contact switch is configured to, when the buckle fits the tongue, trigger the locking component to move to the contact position so that the buckle is driven to move down the guide rail; and to, after the button is connected with the locking component and pressed, trigger the locking component to move to the contact position so that the buckle is driven to move up the guide rail. Two ends of the bidirectional coil spring are connected with the buckle and the guide rail, respectively. The buckle device of the safety belt is high in reliability and low in cost.
