The sliding sleeve 4 and the limiting boss 2-1 are located on opposite sides of the bottom of the suitcase 2. One end of each of the two sliding rods 3 is connected to the tail crossbeam 1-3, and the other end is connected to both ends of a connecting rod 5. The connecting rod 5 is connected to two longitudinal beams 1-1. During riding, the limiting boss 2-1 is positioned inside the tail crossbeam 1-3. By hinged the suitcase 2 to the sliding sleeve 4 and designing the limiting boss 2-1, the suitcase of this application has two states: riding state and dragging state. In addition, a limiting groove can be provided at the end of the limiting boss 2-1. When riding, the limiting groove is limited to the tail beam 1-3 to prevent the suitcase 2 from sliding along the slide bar 3.

[0030] The usage process of this utility model's suitcase is as follows: When riding, the suitcase 2 and the mounting bracket 1 are essentially vertical. At this time, the sliding sleeve 4 on one side of the bottom of the suitcase 2 is located inside the sliding rod 3, and the other side is supported on the mounting bracket 1 and limited by the limiting boss 2-1 or the limiting groove of the limiting boss 2-1 to stably limit the bottom of the suitcase 2, preventing it from sliding along the sliding rod 3 during riding. Pulling up the handlebar 15 of the suitcase 2 serves as a backrest during riding. When riding, the user sits on top of the suitcase 2 with their feet on the mounting bracket 1, and controls steering and speed by controlling the handlebars 9 and the throttle on the handlebars 9.

[0031] When the battery is low and towing is required, retract the lever 15, rotate and push the suitcase 2 backward so that the sliding sleeve 4 is located at the end of the sliding rod 3, the limiting groove 2-3 and the connecting seat 11 form a limiting fit, and finally loosen the locking nut 14, rotate the handlebar 9 relative to the connecting tube 16 and place it in the groove 2-2, and lift the head crossbeam 1-2 upward to achieve towing.
