The invention discloses a non-symmetric repulsion mechanism. The non-symmetric repulsion mechanism comprises a transmission rod, a main quick repulsion unit, an auxiliary quick repulsion unit and a buffer unit. The main quick repulsion unit is composed of a movable repulsion coil and a first fixed repulsion coil. The auxiliary quick repulsion unit is composed of a movable repulsion aluminum plate and a second fixed repulsion coil. The movable repulsion coil and the movable repulsion aluminum plate are fixed to the transmission rod, and the first fixed repulsion coil and the second fixed repulsion coil are fixed to a repulsion mechanism coil mounting plate. The non-symmetric repulsion mechanism makes full use of the characteristic of high efficiency under heavy load of a coil-coil type repulsion structure to improve the driving efficiency of the repulsion mechanism and reduces the collision between the repulsion plate and the repulsion coil as well as between the repulsion coils to prolong the service life of the repulsion mechanism. A user can flexibly choose an opening unit and a closing unit as application occasion required. The non-symmetric repulsion mechanism is simple in structure, quick in movement, high in drive efficiency, long in service life and flexible in operation.
