[0028] In this embodiment, the outer ends of the second locking rod 14, the screw 16, and the fastening screw 6 are all provided with a toggle block.

[0029] Overall Motion Principle: This easy-to-ride suitcase combines the functions of a traditional suitcase with cycling functionality. When in riding mode, the drive wheel 8 at the rear of the suitcase body 1 rotates under the force generated by the user's feet pushing against the ground, thus propelling the suitcase forward. The steering wheel 2 at the front is connected to the handlebar 5 operated by the user's hand via a steering lever 3. By turning the handlebar 5, the user causes the steering lever 3 to drive the steering wheel 2 to change direction, thus steering the suitcase, just like controlling the riding direction and route on a regular bicycle.

[0030] Pedal assembly adjustment principle: The pedal assembly can be flexibly adjusted to accommodate users of different heights. The support plate 11 is fixed to the main body 1 of the trolley case 1 by screws 16 at both ends and screw holes 15 on both sides. When the position of the support plate 11 needs to be adjusted, the screws 16 are loosened, and the support plate 11 can slide on the second guide rail 17. The second guide rail 17 passes through the second cavities at both ends of the support plate 11. Since the cross-section of the second guide rail 17 is T-shaped, it can prevent the support plate 11 from falling off during sliding. After adjusting to the appropriate position, the screws 16 are tightened to fix it. The pedal body 13 is sleeved on the first guide rail 12 of the support plate 11. The first guide rail 12 passes through the first cavity of the pedal body 13. Similarly, the T-shaped cross-section of the first guide rail 12 ensures the stability of the sliding of the pedal body 13. When it is necessary to adjust the position of the pedal body 13, loosen the second locking rod 14 so that one end of it is disengaged from the contact with the first guide rail 12 or unscrewed from the groove inside the slot 10. At this time, the pedal body 13 can slide along the first guide rail 12. After adjusting to the appropriate position, tighten the second locking rod 14 so that one end of it contacts the first guide rail 12 again or is inserted into the groove and threadedly connected, thereby fixing the position of the pedal body 13.

[0031] Adjustment principle of steering rod 3 and handle 5: The push rod 4 at the top of steering rod 3 can extend and retract inside steering rod 3. When it is necessary to adjust the height of push rod 4, loosen the first locking rod 7 so that one end is out of contact with push rod 4. At this time, push rod 4 can be moved up and down. After adjusting to a suitable height, tighten the first locking rod 7 so that it contacts push rod 4 again, thereby limiting and fixing push rod 4. Handle 5 is connected to push rod 4 through fastening screw 6. When it is necessary to adjust the angle of handle 5 or to assemble, loosen fastening screw 6 to adjust handle 5 accordingly. After adjustment, tighten fastening screw 6 so that it is inserted into push rod 4 and threadedly connected, thereby fixing handle 5.

[0032] 1) Prepare the pedal adjustment assembly: Pull the pedal body 13 out of the slot 10, find the actuating block at the outer end of the second locking rod 14, rotate the actuating block to loosen the second locking rod 14, so that the pedal body 13 can slide along the first guide rail 12.

[0033] If the height of the support plate 11 needs to be adjusted, locate the actuating block at the outer end of the screw 16, rotate and loosen the screw 16 so that the support plate 11 can slide on the second guide rail 17, adjust the support plate 11 to the appropriate upper and lower position, and then tighten the screw 16.

[0034] When the pedal body 13 needs to be stored, rotate the toggle block at the outer end of the second locking rod 14 again to loosen the second locking rod 14, remove the pedal body 13 from the support plate 11, insert the pedal body 13 into the empty slot 10, and then insert one end of the second locking rod 14 into the groove inside the empty slot 10 and thread it in.

[0035] 2) Adjust the steering rod 3 and handle 5: Locate the actuating block at the outer end of the first locking rod 7, rotate to loosen the first locking rod 7, move the top rod 4 up and down to the appropriate height, and then tighten the first locking rod 7.

[0036] Locate the actuating block at the outer end of the fastening screw 6, rotate it to loosen the fastening screw 6, adjust the handle 5 to a suitable angle, and then tighten the fastening screw 6.

[0037] To begin riding: The user holds the handlebars 5 with both hands and places both feet on the pedals 13 on either side. By pushing off the ground with their feet, the drive wheels 8 rotate, propelling the suitcase forward. Simultaneously, by turning the handlebars 5, the user controls the direction of the steering wheels 2 using the steering lever 3, thus achieving steering during the ride.

[0038] The pedal assembly is flexibly adjustable in both forward / backward and up / down positions to meet the needs of users of different heights. Users can adjust the pedals to a suitable position according to their own situation, allowing their feet to rest comfortably on the pedals. This avoids the discomfort caused by the fixed footrest position of traditional rolling suitcases, greatly improving riding comfort.

[0039] The outer ends of the second locking rod 14, fastening screw 6, screw 16 and other adjusting components are equipped with toggle blocks. Without the need for additional tools, users can easily adjust and fix the positions of the pedal assembly, steering rod 3 and handle 5 by simply turning the toggle blocks by hand. The operation is simple and convenient, saving time and effort.

[0040] In this embodiment, the cross-sections of the first guide rail 12 and the second guide rail 17 are both T-shaped.

[0041] In this embodiment, a reinforcing frame 9 is provided on the outer wall of the suitcase body 1.

[0042] The first guide rail 12 and the second guide rail 17 both have a T-shaped cross-section. This design effectively prevents the pedal body 13 and the support plate 11 from coming off during sliding, ensuring the stability of the pedal assembly during use. At the same time, a reinforcing frame 9 is provided on the outer wall of the suitcase body 1, which enhances the overall structural strength of the suitcase, making it more stable and durable during riding, able to withstand a certain amount of impact, and extending the service life of the suitcase.

[0043] The pedal body 13 can be inserted into the slot 10 for storage, the top rod 4 can be retracted into the steering rod 3, and the handle 5 can also be adjusted appropriately. When the riding function is not used, the suitcase can be restored to a shape close to that of a traditional suitcase, which is convenient for storage and carrying, does not take up too much space, and is convenient for use in different scenarios.
