[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figures 1 to 4 As shown, a trolley case includes: a case body 2 and a folding stool assembly 3. The case body 2 is provided with a reinforcing part 21. The folding stool assembly 3 is mounted on the reinforcing part 21 and includes a first plate 31, a second plate 32 and at least two support legs 33. The first plate 31 and the second plate 32 are pivotally connected to the reinforcing part 21, and the support legs 33 are simultaneously pivotally connected to the first plate 31 and the second plate 32. The folding stool assembly 3 can switch between a folded state and an unfolded state. In the folded state, the first plate 31, the second plate 32 and the support legs 33 are all parallel to the reinforcing part 21. In the unfolded state, the first plate 31 and the second plate 32 are perpendicular to the reinforcing part 21, and the support legs 33 are parallel to the reinforcing part 21.

[0027] In this application, the core design of this suitcase lies in the unique collaborative working mechanism between its folding stool assembly 3 and the main body 2. When the user needs to use the folding stool, the folding stool assembly 3 is operated first. Since the first plate 31 and the second plate 32 are pivotally connected to the reinforcing part 21 of the main body 2, and the support leg 33 is simultaneously pivotally connected to the first plate 31 and the second plate 32, by manually rotating the first plate 31 and the second plate 32 around the pivot point with the reinforcing part 21, it gradually changes from a folded state parallel to the reinforcing part 21 to an unfolded state perpendicular to the reinforcing part 21. During this process, the support leg 33, which was originally parallel to the reinforcing part 21, changes its connection point position as the first plate 31 and the second plate 32 rotate, ultimately making the support leg 33 also parallel to the reinforcing part 21, thus forming a stable support structure on the ground for the user to sit on.

[0028] After use, reverse the operation to rotate the first plate 31 and the second plate 32 back to the position parallel to the reinforcing part 21. The support leg 33 also returns to its initial state, completing the folding of the folding stool assembly 3 and making it fit against the reinforcing part 21 of the main body 2 without affecting the normal dragging and storage of the suitcase.

[0029] This application greatly solves the problem of rest for users when facing situations with large crowds and a shortage of external seats during travel. On the other hand, this folding stool component 3 serves as a temporary small table for placing items. When not in use, the folding stool component 3 is in a folded state, parallel to the reinforcing part 21, and closely attached to the main body of the box 2, taking up almost no extra space.

[0030] Specifically, the bottom of the box body 2 has multiple sets of movable wheels 22. When unfolded, the lower end of the support foot 33 is flush with the lower end of the movable wheel set 22.

[0031] When the folding stool assembly 3 is unfolded, the flat bottom of the moving wheel set 22 plays a crucial role; when the user sits on the folding stool to rest, even if the body moves slightly or the posture is adjusted, the suitcase will not tip over or shake due to a wheel being too high or too low, ensuring the user's safety while resting.

[0032] Specifically, the first plate 31 is provided with a first receiving groove 311, and the second plate 32 is provided with a second receiving groove 321. When the plate is folded up, the support foot 33 can be at least partially hidden in the first receiving groove 311 and the second receiving groove 321.

[0033] When the suitcase is in the folded state, the support foot 33 can be at least partially hidden within the first receiving groove 311 of the first plate 31 and the second receiving groove 321 of the second plate 32. This design effectively avoids the support foot 33 occupying additional external space when stored. Preferably, the support foot 33 can be completely hidden within the first receiving groove 311 and the second receiving groove 321, and the outer surface of the support foot 33 is flush with the outer surfaces of the first plate 31 and the second plate 32.

[0034] Specifically, the lower ends of the first plate 31 and the second plate 32 are pivotally connected to the reinforcing part 21.

[0035] Specifically, the reinforcing part 21 is provided with a third receiving groove 211, and when in the retracted state, the first plate 31 and the second plate 32 are at least partially hidden in the third receiving groove 211.

[0036] When the first plate 31 and the second plate 32 are at least partially hidden in the third accommodating slot 211 in the folded state, the overall space layout of the suitcase is optimized more efficiently. During carrying, the compact structure also reduces the encroachment on the surrounding space.

[0037] Furthermore, an elastic buckle or magnetic fixing device is provided in the third receiving slot 211. When the first plate 31 and the second plate 32 are stored therein, they can be automatically locked or magnetically fixed to prevent them from accidentally popping out during transportation due to bumps or shaking, thus enhancing the stability in the stored state.

[0038] Specifically, the first plate 31 has first mounting grooves 312 on both sides, and a first connector is installed in the first mounting groove 312. The first connector is pivotally connected to the side wall of the third receiving groove 211.

[0039] Specifically, the second plate 32 has second mounting grooves 322 on both sides, and a second connector is installed in the second mounting groove 322. The second connector is pivotally connected to the side wall of the third receiving groove 211.

[0040] The first and second connectors are rotating pin structures, which are existing technologies and will not be described in detail here.

[0041] The design of the first mounting groove 312 and the second mounting groove 322 is to facilitate the connection between the first connector, the second connector and the side wall of the third receiving groove 211. Specifically, the pivot connection is achieved by fixing a threaded rod to the side wall of the third receiving groove 211, then passing the rod through the first connector or the second connector, and finally being stopped by a nut.

[0042] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0043] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
