A through groove 7 is opened on the suitcase body 1 in the groove 4, and a baffle 8 is hingedly arranged in the through groove 7, and a twist spring is installed at the hinge to apply torsional force to the baffle 8. A limiting plate 801 is installed on the baffle 8. This arrangement facilitates the fixation of the back panel 10.

[0041] A first receiving groove 6 for receiving the electric roller 22 is provided on the luggage case body 1 below the groove 4. This arrangement facilitates the placement of the electric roller 22 when the folding frame 9 is in the storage state.

[0042] The fixing mechanism 19 includes a slide 1901, a swing arm 1906 and a hook 1907. A cavity 1001 is provided in the back plate 10. A limit slide 1903 and a rotating shaft 1909 are arranged transversely in the cavity 1001 in the back plate 10. A strip hole 1902 is provided on the slide 1901. The strip hole 1902 is slidably sleeved on the limit slide 1903. A plurality of springs 1904 are connected between the inner wall of the strip hole 1902 and the limit slide 1903. An arc groove 1905 is provided, and a swing arm 1906 is rotatably provided on the rotating shaft 1909. An arc block 1908 is fixedly provided at one end of the swing arm 1906, and the arc block 1908 is located in the arc groove 1905. A hook 1907 is fixed at the other end of the swing arm 1906. A pull ring 1910 is fixedly provided on the swing arm 1906 in the cavity 1001. The lock tongue 17 matches the hook 1907, which facilitates the fixation of the folding frame 9 in the unfolded or stored state, and facilitates the use of the device.

[0043] The pull ring 1910 is connected to a T-shaped handle 20 through a pull rope 21. The handle 20 is plugged into the top of the backboard 10. Footrests 24 are fixedly provided on the side walls on both sides of the wheel frame 23, which are convenient for stepping on the foot and can limit the handrail 12 when in use. Reinforcement rods 18 are fixedly provided between the support rods 14 to strengthen the support rods 14 to prevent deformation. The roller 3 is a universal wheel. After the folding frame 9 is unfolded, the suitcase body 1 tilts, and the roller 3 of the suitcase body 1 that touches the ground deflects along the direction of force and turns to roll along the direction of force, which is convenient for use in different states of the device.

[0044] Working principle: A folding frame 9 is installed on the suitcase body 1, and the back panel 10 on the folding frame 9 is installed on the rectangular tube 5 in the groove 4; during installation, the baffle 8 is rotated to disengage the baffle 8 from the through groove 7, and then the large cap nails 1002 installed on the back panel 10 are respectively inserted into the large hole ends of the corresponding limiting holes 501, and the back panel 10 is moved upward to move the large cap nails 1002 to the small hole ends of the corresponding limiting holes 501 for limiting. Finally, the baffle 8 is rotated to make the baffle 8 enter the through groove 7 to support the back panel 10. Under the action of the torsional force of the hinge spring, the baffle 8 can be firmly fixed in the through groove 7 to prevent the back panel 10 from falling off or displacement. This arrangement facilitates the connection between the suitcase body 1 and the folding frame 9, and does not require the use of other auxiliary devices, and is very convenient to install and disassemble.

[0045] When in use, the storage box 2 can store items and can also serve as a cushion for the user when unfolding. When the folding frame 9 needs to be unfolded, the fixing mechanism 19 needs to be opened, and by pulling the handle 20, the side of the curved block 1908 of the swing arm 1906 moves downward under the drive of the pull rope 21, squeezing the slide 1901 to move backward, and at the same time, the hook 1907 moves upward, which can release the restriction of the lock tongue 17 on the handrail 12;

[0046] Then, the locking tongue 17 on the T-shaped slider 16 is moved up to the hook 1907 of the upper fixing mechanism 19, and the handle 20 is released. Under the action of the spring 1904, the slide 1901 moves forward, and at the same time, the arc block 1908 is squeezed and pushed up, and the hook 1907 moves down, restricting the locking tongue 17 on the T-shaped slider 16. At this time, the folding frame 9 can be unfolded, and the folding frame 9 can be used as a scooter by cooperating with the electric roller 22 on the wheel frame 23 below the handrail 12 and the roller 3 on the bottom of the luggage case body 1, which can save physical energy for the user and is very convenient to use, and can meet various usage needs;

[0047] Moreover, the suitcase body 1 is in an inclined state at this time, and forms a triangle with the folding frame 9 as a whole, which has good stability. Moreover, the folding frame 9 and the suitcase body 1 have three wheels on the ground, which is not easy to tip over, has low driving difficulty, and is convenient for users to operate.

[0048] When folding is required, the same operation is performed by pulling the handle 20 to release the restriction of the locking tongue 17 on the T-shaped slider 16 by the fixing mechanism 19. The T-shaped slider 16 moves downward, and the folding frame 9 is folded to fit onto the suitcase body 1. The locking tongue 17 on the handrail 12 is inserted into the hook 1907. The handle 20 is released, and the slide 1901 moves forward under the action of the spring 1904, while squeezing and pushing the arc block 1908 upward, and the hook 1907 moves downward to restrict the locking tongue 17 on the handrail 12. At this time, the folding frame 9 on the suitcase body 1 is in a folded state, which can save space, facilitate storage and transportation, and is easy to use.

[0049] The user can use the handle 26 to adjust the direction of travel, and can also adjust the height of the handle 26 by adjusting the extension length of the pull rod 25 on the handrail 12, so as to adapt to users of different heights, improve the stability and safety of use, and facilitate better support for users.

[0050] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
