[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.

[0051] Reference Figure 1-12 As shown, the present application proposes a multifunctional luggage case, including a case body 1 and a frame 2 that can be combined or separated with each other, so that in some scenarios, the case body 1 and the frame 2 can be used separately, for example, the case body 1 can be used to place non-moving items, and the frame 2 can also be used for riding; and when the two are combined, they can be the same as the products in the prior art, as a device that can carry items and can be used for children to ride. The specific implementation will be further described below.

[0052] The frame 2 of the multifunctional suitcase includes a vertical rod 21 and a lower support portion 22 arranged at the lower end of the vertical rod 21. The lower support portion 22 is mainly used to support the lower part of the box body 1. In some cases, that is, when the frame 2 is separated from the box body 1, the lower support portion 22 can be used as a footrest for children to ride.

[0053] In order to expand its functionality, in a further implementation, the frame 2 further includes an upper support portion 23 disposed on the upright pole 21, and a support frame 24 is hinged on the upper support portion 23, and the support frame 24 can form an expanded state or a folded state with the upright pole 21. Figure 1-2 and Fig.11 As shown, the frame 2 is in the folded state; Figure 3-4 As shown, the frame 2 is in the unfolded state. In the folded state, the suitcase can be statically stored or moved independently, which is basically the same as a conventional trolley suitcase. In the unfolded state, when the frame 2 is combined with the box body 1, the upper support part 23 on the box body 1 can be used to rest the child's buttocks, thereby realizing the first way of riding; when the frame 2 is separated from the box body 1, the unfolded frame 2 can be used as a separate riding vehicle, the upper support part 23 can be used to rest the child's buttocks, and the lower support part 22 is used as a footrest to rest the feet, thereby realizing the second way of riding.

[0054] The body 1 of the multifunctional suitcase is provided with a buckle structure 3 for engaging with the upright pole 21 , and the body 1 can be combined with the frame 2 or detached from the frame 2 by locking or unlocking the buckle structure 3 .

[0055] There are many ways to implement the buckle structure 3, such as using a conventional buckle or a strap / tie.

[0056] As a preferred method, this method can achieve reliable connection and convenient operation. Figure 7-10 As shown, the buckle structure 3 includes a connecting portion 31, a first clamping member 32, a second clamping member 33, and a locking piece 34. Specifically, an embracing portion 311 is provided on the connecting portion 31, the first end of the embracing portion 311 is used to rotate and connect the first clamping member 32, and the other end is formed with a convex edge 3111; the other end of the first clamping member 32 is hinged to one end of the locking piece 34 and rotates around the first axis L1; one end of the second clamping member 33 is hinged to the middle of the locking piece 34 and rotates around the second axis L2, and the other end is formed with a hook portion 331; the vertical rod 21 is placed in the embracing portion 311, and the position of the first axis L1 and / or the second axis L2 and the first end of the embracing portion 311 is changed by rotating the locking piece 34, so that the hook portion 331 and the convex edge 3111 are engaged or released.

[0057] In simple terms, the relative deflection angle of the locking piece 34 in the buckle structure 3 is utilized to pull the hook portion 331 on the second clip 3111 tight or away from the convex edge 3111, thereby achieving unlocking or locking. Fig.10 As shown, it also shows the structural schematic diagram from the locked state to the unlocked state.

[0058] In order to save labor in operation, further, a first distance is formed between the first axis L1 and the second axis L2, and a second distance is formed between the second axis L2 and the outer end of the locking piece 34, and the first distance is smaller than the second distance. In this way, the locking piece 34 forms a lever of different lengths in the buckle structure 3, and the section that is manually pressed or pulled constitutes the longer section of the lever, thereby achieving a labor-saving effect.

[0059] For easy assembly, the connecting portion 31 is connected to the luggage case via a fastener 35. For example, a plate-like structure is formed on the connecting portion 31, and the plate-like structure is fixed to the wall of the case 1 via a plurality of screws.

[0060] For further cooperation between the box 1 and the frame 2: refer to Figure 4-6As shown, the lower part of the box body 1 is formed with a recessed part 11 and a protruding part 12, and the lower support part 22 is semi-open bucket-shaped. The lower support part 22 is provided with a support block 221 and a reinforcing rib 222. The support block 221 is used to support the protruding part 12, and the contour of the reinforcing rib 222 is adapted to the curvature of the recessed part 11. In this way, an effective support is formed for the lower part of the box body 1, and the overall strength is improved. The setting of the reinforcing rib 222 utilizes the internal space of the lower support part 22 itself, ensuring a compact structure while improving the strength of the lower support part 22.

[0061] In order to facilitate movement, first rollers 223 are provided on both sides of the lower support portion 22, and two second rollers 241 are provided at the lower end of the support frame 24. When folded, the second roller 241 is placed in the area between the two first rollers 223. As a further preferred embodiment, when folded, the second roller 241 and the first roller 223 maintain pressure contact with the ground together.

[0062] Regarding the specific implementation of the folding and unfolding of the frame 2, further reference is made to Fig.12 As shown, a locking structure 4 for locking the support frame 24 is disposed in the upper support portion 23 , and the locking structure 4 includes an unlocking block 41 , a locking pin 42 , a rotation matching portion 43 and a spring 44 .

[0063] Specifically, the unlocking block 41 is movably arranged in the upper support part 23, and is driven by a spring 44 to return to its original position; the rotating matching part 43 is rotatably arranged on both sides of the upper support part 23 and is used to connect the upper end of the support frame 24, that is, the upper end of the support frame 24 is fixedly inserted on the rotating matching part 43 and follows its rotation; a slide groove 431 is arranged in the rotating matching part 43, and a limiting groove 432 at at least two different positions connecting the slide groove 431 is arranged; the locking pin 42 passes through the unlocking block 41, and both ends are placed in the limiting grooves 432 to move and can be selectively locked in different limiting grooves 432; the locking pin 42 is driven to disengage the lock by pressing the unlocking block 41, and then it can be locked in one of the limiting grooves 432 as needed to achieve the switching between the unfolded state and the folded state.

[0064] Preferably, the upper support portion 23 includes a seating portion 231, the seating portion 231 is located between the upright pole 21 and the box body 1, and the unlocking block 41 is disposed in the seating portion 231 and does not protrude from the seating portion 231. Thus, when the frame 2 needs to be unfolded, manual operation can be performed at the upper position of the box body 1, which is more convenient.

[0065] Further features of the vertical pole 21: the vertical pole 21 is retractable and is provided with a handle 211 and an armrest 212. The distance between the handle 211 and the armrest 212 and the distance from the upper support portion 23 are adjustable, so that it can be used according to different requirements.
