The invention discloses a locking mechanism, an electric vehicle and a locking method. The locking mechanism is used for locking a battery pack to a vehicle body, the locking mechanism comprises a lock head and a lock body, the lock head comprises a fixing part and a rotating part, the fixing part is fixed to the vehicle body, the rotating part is connected to the fixing part through threads, andthe lock body comprises a connecting part connected with the rotating part; and the rotating part and the fixing part relatively rotate, so that the rotating part pulls the connecting part to lock thebattery pack on the vehicle body. According to the locking mechanism, screw-in and screw-out are not needed in threaded fit, the problems of inaccurate threaded head position butt joint and thread abrasion possibly existing in threaded butt joint screwing are avoided, large butt joint errors are allowed, the structure is simple and reliable, and the production and maintenance cost is low.
