DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present disclosure, and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present disclosure.

[0033] It should be noted that when an element is referred to as being fixedly connected to another element, it can be directly fixedly connected to the other element or the element can be indirectly fixedly connected to the other element via one or more intermediate elements. When an element is referred to as being directly connected to another element, it can be directly connected to the other element or the element can be indirectly connected to the other element via one or more intermediate elements. In the description of the present disclosure, it should be noted that the terms upper, lower, bottom, rear, side, etc. indicate the orientation or positional relationship based on the orientation shown in the drawings. The positional relationship is only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the referenced device or element must have a specific orientation, be constructed, and be operated in a specific orientation. Therefore, the positional relationship should not be understood as a limitation of the present disclosure.

[0034] The present embodiment provides a multifunctional case with an integrated folding table function, comprising a case lid 1 and a case body 2 as shown in FIG. 1. The case body 2 comprises two buckles 24, and the case lid 1 comprises two buckling grooves 13, as shown in FIG. 2, configured to correspond to the two buckles 24. As shown in FIG. 11, the two buckling grooves 13 and the two buckles 24 are configured to be buckled to each other to achieve opening and closing of the case body 2 and the case lid 1. A connection method between the case lid 1 and the case body 2 is not a main technical feature of the present disclosure. It is only an illustrative explanation. In other possible implementations, those skilled in the art can use any existing detachable connection method to open and close the case lid 1 and case body 2.

[0035] Referring to FIGS. 2 to 7, a structure of the case lid 1 is shown. Specifically, an end surface of the case lid 1 defines a panel 11, a pair of foldable supporting frames 12 are pivotally connected to the case lid 1, and an outer side of the case lid 1 comprises the buckling grooves 13. Specifically, referring to FIG. 3, the case lid 1 comprises two lid sides 111 opposite to each other, and each of the two lid sides 111 comprises two pivoting points 112. Each of the two lid sides 111 comprises two position-limiting protrusions 113 disposed between the two pivoting points 112. The two pivoting points 112 are pivotally connected to pivoting ends of the pair of foldable supporting frames 12, and the two position-limiting protrusions 113 are configured to limit a rotating angle of the pair of foldable supporting frames 12 to limit an unfolding degree of the pair of foldable supporting frames 12.

[0036] Further, as shown in FIGS. 3, 5, and 6, in this embodiment, each foldable supporting frame of the pair of foldable supporting frames 12 is substantially U-shaped, and each foldable supporting frame of the pair of foldable supporting frames 12 comprises two supporting arms 122 parallel to each other. First ends of the two supporting arms 122 are connected together by a connecting arm 123. Second ends of the two supporting arms 122 away from the connecting arm 123 define the pivoting ends. The pivoting ends of each foldable supporting frame of the pair of foldable supporting frames 12 are bent to form position-limiting members 121.

[0037] In this embodiment, each foldable supporting frame of the pair of foldable supporting frames 12 comprises two pivoting ends of the pivoting ends. The two pivoting ends are respectively pivotally connected to one of the two pivoting points 112 on a first one of the two lid sides 111 and one of the two pivoting points 112 on a second one of the two lid sides 111 that are disposed on a same side of the case body 2. In other possible implementations, the two pivoting ends can be respectively pivotally connected to the two pivoting points 112 on a corresponding one of the two lid sides 111, or the two pivoting ends can be pivotally connected to one of the two pivoting points 112 on the first one of the two lid sides 111 and one of the two pivoting points 112 on the second one of the two lid sides 111 that are disposed on different sides of the case body 2.

[0038] In this embodiment, the pair of foldable supporting frames 12 are U-shaped. When the pair of foldable supporting frames 12 are unfolded, the connecting arm 123 has a larger contact area with ground, so the pair of foldable supporting frames 12 are more stable. Compared with four linear support frames, the connecting arm 123 can also limit a relative position between the two supporting arms 122 connected to the connecting arm 123, further increasing stability of the pair of foldable supporting frames 12. According to the above technical concept, in other possible implementations, each of the pair of foldable supporting frames 12 comprises two supporting arms 122 and a connecting arm 123 connected to the two supporting arms 122. The two supporting arms 122 and the connecting arm 123 can be arc-shaped, zigzag-shaped, or wave-shaped. Suboptimally, the connecting arm 123 does not need to be in contact with the ground when the pair of foldable supporting frames 12 are unfolded, and the connecting arm 123 can be connected to the first ends of the two supporting arms 122, middles of the two supporting arms 122, or the first end of one of the two supporting arms 122 and the middle of a second one of the two supporting arms 122.

[0039] A cooperative relationship between the pair of foldable supporting frames 12 and the case lid 1 will be described below. The pivoting ends of each foldable support frame of the pair of foldable supporting frames 12 are bent to form the position-limiting members 121, and distal ends of the position-limiting members 121 are movably pivotally connected to the two pivoting points 112. When the pair of foldable supporting frames 12 are in a folded state, a structure of the case lid 1 is as shown in FIGS. 2 and 3. The pair of foldable supporting frames 12 are completely stored in the case lid 1. Referring to FIG. 4, at this time, the position-limiting members 121 are not in contact with the two position-limiting protrusions 113. Afterwards, the pair of foldable supporting frames 12 are rotated around the two pivoting points 112 in a direction away from the panel 11 until the pair of foldable supporting frames 12 reach an unfolded state as shown in FIGS. 5 and 6. At this time, the pair of foldable supporting frames 12 support the case lid 1 to define a table. As shown in FIG. 7, the position-limiting members 121 are in contact with the two position-limiting protrusions 113 so that the pair of foldable supporting frames 12 cannot be rotated outward.

[0040] Furthermore, in this embodiment, the pair of foldable supporting frames 12 are made of a hard metal tube, which has good supporting capacity and is small in size and light in weight. When the pair of foldable supporting frames 12 are unfolded, the pair of foldable supporting frames 12 can better support the case lid 1. When the pair of foldable supporting frames 12 are folded and stored in the case lid 1, the pair of foldable supporting frames 12 require less space and are light in weight, making the multifunctional case easy to carry.

[0041] In addition, the multifunctional case provided by the present embodiment is also a trolley case with two rollers 22 and a stop structure (i.e., position-stopping protrusions 23). Referring to FIGS. 8 to 10, in the present embodiment, the two rollers 22 are opposite to each other and disposed on a rear of two sides of the case body 2. An outer tube of a pulling rod 21 is fixedly connected to a rear surface of the case body 2. The pulling rod 21 is located between the two rollers 22, and the position-stopping protrusions 23 are disposed on a side of a lower surface of the case body 2 away from the pulling rod 21 and the two rollers 22. A height of the position-stopping protrusions 23 is equal to a height between a lowermost edge of the two rollers 22 and the lower surface of the case body 2. When the multifunctional case needs to be moved, the pulling rod 21 is pulled to tilt the case body 2 backward and the position-stopping protrusions 23 leave the ground. When the multifunctional case needs to be stopped from moving, the case body 2 is laid flat. At this time, the position-stopping protrusions 23 are in contact with the ground to prevent the two rollers 22 from moving unintentionally.
