After the second body 12 of the box 1 is unfolded relative to the first body 11, the gap formed by the slope 454 can avoid the second body 12, which is beneficial to increasing the unfolding angle of the second body 12.

Referring to fig. 3 and 8, in the present embodiment, a pull rod 8 for dragging or pushing the electric luggage to move is installed on the right side wall of the luggage body 1. The right side wall of the box body 1 corresponds to the right wall of the first split body, and the pull rod 8 is correspondingly installed on the first split body 11 of the box body 1. The tie rod 8 comprises a first base 81, two telescopic struts 82 connected to the first base 81, a second base 83 to assist in assembling the two struts 82, and a handle 84 to connect the two struts 82. The number of the struts 82 may be one. The first base 81 and the second base 83 are both located on the right wall of the first body 11. Wherein: the first base 81 is installed at the front end of the right wall of the first split body, and avoids the installation position of the steering rod 31; the second base 83 is mounted on the rear end of the right wall of the first split body. The first and second bases 81 and 83 avoiding the installation position of the steering rod 31 can maximally utilize the front-rear length of the housing 1 to install the strut 82 having a relatively long length, thereby increasing the stretching length of the tie rod 8. The pull rod 8 has a tensile length of 1.2 to 1.5 m, and is suitable for children and adults. When a user drags or pushes the electric luggage case to move through the pull rod 8, the case body 1 inclines to the ground, the two rear wheels 22 are separated from the ground, the two front wheels 21 are in contact with the ground, and the electric luggage case is used as a common luggage case for the user.
