[0026] An obstacle avoidance structure of a road surface scanning and recognition system for an active suspension of a passenger vehicle comprises a vehicle 1, a camera 2 is fixedly installed on the top of the vehicle 1, a mounting template 3 is arranged on the front side surface of the vehicle 1, a mounting compartment 4 is provided inside the mounting template 3, a sensor module 401, a limiting sleeve 402, a limiting column 403, a moving bar 404 and a driving motor 405 are respectively arranged inside the mounting compartment 4, a laser sensor 4011 and an ultrasonic sensor 4012 are respectively arranged on the front side surface of the sensor module 401, a gear 4051 is fixedly sleeved on the output end of the driving motor 405, a control box 5 is fixedly installed on the front side of the vehicle 1, and an actuator 501 and a vehicle-mounted computer 502 are respectively fixedly installed on the bottom end of the control box 5;
[0027] It should be noted that the installation template 3 is embedded and connected to the front surface of the vehicle 1 through a clamp;
[0028] Specifically, the front ends of the limiting sleeve 402 and the moving bar 404 are fixed to the rear surface of the sensor module 401, the front end of the sensor module 401 is sealed and fits through the front inner wall of the installation bin 4 and extends outward, the rear end of the limiting column 403 is welded to the rear inner wall of the installation bin 4, and its front end slides through the rear end surface of the limiting sleeve 402 and extends inward, the top surface of the driving motor 405 contacts the top inner wall of the installation bin 4, the outer surface of the moving bar 404 is provided with a rack, and the gear 4051 is meshed and connected with the rack;
[0029] In this embodiment, the driving motor 405 is mainly used to drive the gear 4051. Under the meshing transmission of the gear 4051 and the rack, the moving bar 404 drives the sensor module 401 to move, and the limiting sleeve 402 is mainly used to telescopically slide with the limiting column 403, so that the sensor module 401 can maintain a stable state when moving, and the laser sensor 4011 and the ultrasonic sensor 4012 can be stored in the installation bin 4, so as to protect the laser sensor 4011 and the ultrasonic sensor 4012.
[0030] Specifically, the laser sensor 4011, the ultrasonic sensor 4012 and the camera 2 are electrically connected to the vehicle-mounted computer 502 through wires, and the vehicle-mounted computer 502 performs information fusion through the Kalman filter algorithm and is electrically connected to the actuator 501 through wires;
