The invention discloses a safety belt pre-tightening device and a vehicle. The safety belt pre-tightening device comprises a detection mechanism and an execution mechanism, wherein the detection mechanism comprises a detection ball and a shell, the detection ball is movably supported in the shell, the shell is provided with a first electrode layer and a second electrode layer which are spaced in an insulating mode, and the detection mechanism is constructed to enable the detection ball to move in the shell and enable the first electrode layer to be electrically connected with the second electrode layer when the acceleration of the vehicle exceeds a set value; the execution mechanism is electrically connected with the detection mechanism, the detection mechanism outputs an electric signal to the execution mechanism when the first electrode layer is electrically connected with the second electrode layer, and the execution mechanism controls a safety belt to be locked and tightened when receiving the electric signal. According to the safety belt pre-tightening device, the execution mechanism can lock and tighten the safety belt under the working conditions of rapid deceleration or rapid acceleration or sharp turn and the like of the vehicle, and the safety of passengers is guaranteed.
