Asymmetric repulsion mechanism

The utility model discloses an asymmetric repulsion mechanism. The mechanism comprises a transmission bar, a main rapid repulsion unit, a secondary rapid repulsion unit and a buffer unit. The main rapid repulsion unit is formed by a movable repulsion coil and a first fixing repulsion coil. The secondary rapid repulsion unit is formed by a movable repulsion aluminum disc and a second fixing repulsion coil. The movable repulsion coil and the movable repulsion aluminum disc are fixed to the transmission bar. The first fixing repulsion coil and the second fixing repulsion coil are fixed to a repulsion mechanism coil installing plate. The asymmetric repulsion mechanism provided in the utility model fully uses a characteristic that a coil-coil type repulsion structure has high efficiency under a large load to increase repulsion mechanism driving efficiency. The service life of the repulsion mechanism is prolonged through reducing collisions between a repulsion disc and the repulsion coil, and between the repulsion coil and the repulsion coil. According to an application occasion demand, an opening unit and a closing unit can be flexibly selected. The structure of the asymmetric repulsion mechanism is simple and motion is rapid. The driving efficiency is high, the service life is long and operation is flexible.
