The invention discloses an active suspension structure which comprises a linear actuator, a spring assembly, a damper and a mounting frame. The linear actuator is a ball screw assembly which is of a hollow structure and is driven by a motor to do linear motion. The upper end of the spring assembly is connected with the ball screw pair assembly, the lower end of the spring assembly is connected with the mounting frame, and the spring assembly is stretched or compressed along with the movement of the ball screw pair assembly; the damper is arranged in a hollow structure in the linear actuator, and a damper piston is arranged at the front end of the damper; the upper end of the mounting frame is connected with the damper piston, the middle of the mounting frame is connected with the spring assembly, and a mounting hole for connecting a hub is formed in the bottom of the mounting frame; the bottom mounting frame moves up and down along with stretching and compression of the spring assembly. All the components are integrated into one module, all the components are modularized, the height, rigidity and damping characteristics of the suspension can be adjusted in real time, the response speed is high, and the comfort level and durability are improved.
