[0017] Compared with the prior art, the advantages of the present invention are:

[0018] First, the present invention utilizes a trolley case assembly and a mobile assembly. When road conditions are poor, the user can directly control the suitcase's external controller. The controller controls the first and second electric push rods. The first push rod drives the first mounting frame outward and extends the first roller outward. The second push rod then maneuvers the second mounting frame outward, simultaneously extending the second roller outward. This increases the support area of ​​the suitcase's bottom surface, making it more stable on uneven surfaces. This helps prevent the suitcase from tipping or shaking while in motion. The user can adjust the support area of ​​the suitcase's bottom surface at any time using the external controller according to actual road conditions. This flexibility allows the suitcase to better adapt to various complex terrains, such as muddy, potholed, or rocky roads.

[0019] 2. Based on beneficial effect 1, through the provided shock-absorbing assembly, when the bottom of the suitcase body is bumped, the first spring and the second spring will be deformed, and the deformation force will be transmitted to the first damper and the second damper. The first damper and the second damper gradually reduce the fluctuation of the deformation force. When bumps occur, the fixing frame and the clamping rod are locked to fix the mounting block and the suitcase body together. The combined action of the spring and the damper can effectively improve the stability of the suitcase, extend its life, and enhance the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The second mounting frame 27 is used to mount a second roller 28, which is used to enable the suitcase to move. The second rotating shaft 29 allows the second roller 28 to rotate freely.

[0042] Working principle:

[0043] When the road conditions are bad;

[0044] First, the user can directly control the first electric push rod 22 and the second electric push rod 26 through the external controller of the luggage case body 11;

[0045] At this time, the first electric push rod 22 drives the first mounting frame 23 to move outward, and extends the first roller 24 outward, and the second electric push rod 26 moves the second mounting frame 27 outward;

[0046] At the same time, the second roller 28 is extended outward to expand the support area of ​​the bottom surface of the luggage box body 11, so that the luggage box will be more stable on uneven roads;

[0047] This step helps prevent the suitcase from tipping over or shaking while driving.
