The invention relates to the field of automobiles, in particular to a thermoforming tailored blank laser welding integrated door ring and a vehicle. The invention provides a thermal forming tailored blank laser welding integrated door ring which comprises an A column reinforcing plate, an A column roof side rail, a B column reinforcing plate upper section, a B column reinforcing plate lower section, a threshold outer plate, an A column roof side rail patch plate and a B column patch plate. Joint positions of the A-column reinforcing plate, the A-column upper edge beam, the B-column reinforcing plate upper section, the B-column reinforcing plate lower section and the threshold outer plate form a door ring body through laser welding, the A-column upper edge beam patch plate is connected to the A-column upper edge beam and the B-column reinforcing plate upper section through spot welding, and the B-column patch plate is connected to the B-column reinforcing plate upper section through spot welding. The door ring body connected with the A column roof side rail patch plate and the B column patch plate is sequentially subjected to hot stamping forming, laser trimming and hole cutting, and then a door ring finished product is formed.
