[0030] Working principle: When in use, the first box body 1 can be used to load large items, while the second box body 2 can be used to store small items. The driving wheel 10 drives the second box body 2 and thus drives the first box body 1, so that the entire device can be driven to move. When the user needs to sit in the suitcase, the pull block 22 is pulled to drive the pull rod 19 to drive the limit block 20 to disengage from the corresponding limit groove 23, so that the first box body 1 and the second box body 2 are released from the limit, and then the first box body 1 and the second box body 2 are pulled apart. When pulling apart, the stabilizing bar 16 is inside the fixing sleeve 17. The slider 14 slides from the upper part of the slide groove 15 to the lower part of the slide groove 15, and at the same time, under the action of the hinge, the seat cushion plate 13 is driven to escape from the inside of the storage groove 12, and changes from vertical to horizontal to form a seating area, and then the pulled pull block 22 is released, and under the action of the first spring 21 pushing the limit block 20, the limit block 20 is pushed to the inside of another limit groove 23 that needs to be engaged, so as to fix the position of the stabilizer bar 16, and then fix the horizontal seat cushion plate 13, and then the user sits on the seat cushion plate 13, holds the handle 6, and moves with the suitcase as a whole; When the user sits down, the pressure from sitting down will squeeze the buffer plate 29, and the buffer plate 29 will move downward under pressure, thereby squeezing the multiple buffer blocks 28, so that the buffer blocks 28 squeeze the second springs 27, and the springs are compressed to generate elastic force. When the integral luggage box composed of the first box body 1 and the second box body 2 is bumpy during driving, the second springs 27 are repeatedly rebounded due to the force of shaking, and the impact force generated by the bumps is absorbed and buffered, thereby improving the comfort of the user when using; When the user needs to store personal belongings such as mobile phones and chargers, the user puts the personal belongings into the storage box 30 and then turns the knob 34 to drive the stud 33 to rotate. Under the action of the threaded hole 31, the limit plate 35 is driven to move toward the side of the stored items. At the same time, the connecting block 36 slides inside the connecting groove 32 to fix the stored items, thereby reducing the phenomenon that the stored items repeatedly hit the storage box 30 due to bumps.
