[0033] The technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention; it is obvious that the embodiment described above is only one implementation method of the present invention, and all other embodiments obtained by ordinary technicians in this field based on the following embodiments without making any creative work are within the scope of protection of the present invention.
[0034] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be an element in the middle. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an element in the middle. In the present invention, the terms "upper", "lower", "bottom", "back", "side", etc. indicate that the orientation or position relationship is based on the orientation or position relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the present invention.
[0035] This embodiment provides a multifunctional case with an integrated folding table function, including a case lid 1 and a case body 2 as shown in FIG1 . A buckle 24 is provided on the case body 2, and a corresponding position of the case lid 1 is provided with a slot 13 as shown in FIG2 . As shown in FIG11 , the slot 13 and the buckle 24 engage with each other to achieve the closing of the case body 2 and the case lid 1 . The connection method between the case lid 1 and the case body 2 is not a primary technical feature of the present invention and is provided herein for illustrative purposes only. In other possible implementations, those skilled in the art may use any existing detachable connection method to close the case lid 1 and the case body 2 .
[0036] Figures 2-7 illustrate the structure of the lid 1. Specifically, the end face of the lid 1 is a panel 11, to which a pair of foldable support frames 12 are hingedly connected. A retaining slot 13 is defined on the outer side of the lid. Specifically, referring to Figure 3, two hinge points 112 are provided on each of the two opposing sides 111 of the lid 1. Two limiting bumps 113 are positioned between the two hinge points 112 on the same lid side 111. These hinge points 112 are hingedly connected to the hinged ends of the support frames 12. The limiting bumps 113 are used to limit the rotation angle of the support frames 12, thereby limiting the degree of opening.
[0037] Furthermore, it can be seen from Figures 3, 5 and 6 that in this embodiment, the support frame 12 is roughly U-shaped, and the support frame 12 includes two support arms 122 arranged in parallel, one end of the two support arms 122 is connected by a connecting arm 123, and the other end of the support arm 122 away from the connecting arm 123 is a hinged end, and each support frame 12 includes a hinged end bent to form a limiting portion 121.
[0038] In this embodiment, each support frame 12 has two hinged ends, which are respectively hinged to hinge points 112 on the same side of two lid side surfaces 111. In other possible implementations, the two hinged ends can be respectively hinged to two hinge points 112 on the same lid side surface 11, or can be hinged to hinge points 112 on different sides of the lid side surfaces 111.
[0039] In this embodiment, the support frame 12 is U-shaped. When the support frame 12 is opened, the connecting arm 123 has a larger contact area with the ground, thereby providing better support and greater stability. In addition, compared to the four straight support frames 12, the connecting arm 123 can also limit the relative position of the two support arms 122 connected thereto, further increasing the stability of the support frame 12. According to the above technical concept, in other possible implementations, the support frame 12 can also have two support arms 122 and a connecting arm 123 connecting the support arms 122. These support arms 122 and connecting arms 123 can be arc-shaped, broken-line-shaped, or wavy-shaped. Suboptimally, the connecting arm 123 may not abut the ground when the support frame 12 is opened. In this case, the connecting arm 123 can be connected to the ends of the two support arms 122, or to the middle of the two support arms 122, or to the middle of one support arm 122 and to the end of the other support arm 122.
[0040] The following is an explanation of the coordination between the support frame 12 and the box lid 1. The support frame 12 is bent at its hinged end to form a limiting portion 121, and the end of the limiting portion 121 is movably hinged to the hinge point 112. When the support frame 12 is in a folded state, the structure of the box lid 1 is shown in Figures 2 and 3, and the support frame 12 is completely stored in the box lid 1. As can be seen from Figure 4, at this time, the limiting portion 121 is not in contact with the limiting protrusion 113. Afterwards, the support frame 12 rotates along the hinge point 112 in a direction away from the panel 11 until it reaches the open state shown in Figures 5 and 6, at which point the support frame 12 supports the box lid 1 to form a table. Among them, as shown in Figure 7, the limiting portion 121 abuts against the limiting protrusion 113, preventing the support frame 12 from continuing to rotate outward.
[0041] Furthermore, in this embodiment, the support frame 12 is made of a hard metal tube, which has good supporting capacity and is small in size and light in weight. When the support frame 12 is opened, it can better support the box cover 1. When folded and stored in the box cover 1, it requires less space and has a light weight, making it easy to carry.
[0042] Furthermore, the multifunctional case provided in this embodiment is also a trolley case having rollers 22 and a stop structure (i.e., a stop bump 23). Referring to Figures 8-10, in this embodiment, two rollers 22 are positioned opposite each other on the sides and rear of the case 2. The outer tube of a pull rod 21 is fixedly mounted on the rear surface of the case 2, with the pull rod 21 positioned between the two rollers 22. A stop bump 23 is positioned on the lower surface of the case 2, away from the pull rod 21 and rollers 22. The height of the stop bump 23 is equivalent to the distance between the lowest edge of the rollers 22 and the lower surface of the case 2. To move the multifunctional case, simply pull the pull rod 21 to tilt the case 2 backward, and the stop bump 23 will lift off the ground. To stop the case 2 from moving, simply lay the case 2 flat, at which point the stop bump 23 will contact the ground, preventing unintended movement of the rollers 22.
