Car seat safe electromagnetic slide rail assembly

The invention discloses a car seat safe electromagnetic slide rail assembly. The electromagnetic slide rail assembly comprises a slide rail, sliding blocks, a resistance device, a control device and an actuator; a first solenoid is arranged in a cavity of the slide rail; the resistance device is fixed between the two sliding blocks; a second solenoid is arranged in the resistance device, and the current direction of the second solenoid is opposite to that of the first solenoid; the control device comprises a device housing; a third solenoid is arranged in the device housing; the third solenoidand the second solenoid are perpendicular to each other; the actuator comprises an inner sleeve, a compression spring, an outer sleeve, a locking pin and an iron sheet; the inner sleeve is movably sleeved with the outer sleeve; and one end of the locking pin is fixedly connected with the iron sheet. A seat is automatically unlocked and can move forwards by a certain distance in the event of a collision, so that the buffe
