[0031] Refer to Figure 2 , Figure 8 , Figure 9 and Figure 14 , the processes of electric unfolding and contraction of the intelligent electric suitcase of the present application, as well as the left and right steering of the steering handle, are as follows:

[0032] During electric unfolding, the electric telescopic push rod 103 is activated, and its telescopic end extends forward. At this time, the sliding pin 117 gradually slides from the front end to the rear end of the sliding waist-shaped groove 116. The forward extension of the telescopic end drives the transmission link 114 to move forward, the transmission link 114 drives the fifth rotating link 115 to move forward, and the fifth rotating link 115 drives the first rotating link 109 to move forward, thereby driving the front wheel 108 to unfold outward. During the unfolding process of the front wheel 108, it always faces the front of the box body 10. After the front wheel 108 is fully unfolded, the sliding pin 117 synchronously slides to the rear end of the sliding waist-shaped groove 116. At this time, the telescopic end continues to extend forward, and the rear end of the sliding waist-shaped groove 116 pushes the sliding pin 117 forward, and the telescopic end drives the telescopic rod 102 to extend forward. Thus, the entire unfolding process of the electric suitcase ends;

[0033] During electric contraction, the electric telescopic push rod 103 is activated, and its telescopic end retracts backward. At this time, the sliding pin 117 gradually slides from the rear end to the front end of the sliding waist-shaped groove 116. The backward retraction of the telescopic end drives the transmission link 114 to move backward, the transmission link 114 drives the fifth rotating link 115 to move backward, and the fifth rotating link 115 drives the first rotating link 109 to move backward, thereby driving the front wheel 108 to contract inward. During the contraction process of the front wheel 108, it always faces the front of the box body 10. After the front wheel 108 is fully contracted, the sliding pin 117 synchronously slides to the front end of the sliding waist-shaped groove 116. At this time, the telescopic end continues to retract backward, and the front end of the sliding waist-shaped groove 116 pushes the sliding pin 117 backward, and the telescopic end drives the telescopic rod 102 to retract backward. Thus, the entire contraction process of the electric suitcase ends.

[0034] When turning left or right, the steering handle 20 rotates left and right, driving the steering connection member 201 and the steering connection rod 202 to rotate left and right. The steering connection rod 202 drives the fourth rotating link 113 to rotate left and right, and the fourth rotating link 113 drives the second rotating link 110 to rotate left and right, thereby driving the two front wheels 108 to turn left and right.

[0035] Refer to Figure 1 、 Figure 3 and Figure 4 As shown in, on both sides of the connecting pipe 106, there are symmetrically arranged footrest parts 119 for placing the feet of the user when in use. At the rear side of the bottom of the box body 10, there is a rear wheel 120. The number of the rear wheels 120 can be one or two.
