Description

Technical Field

[0001] This utility model relates to the field of luggage technology, specifically to a trolley case with an external extension structure. Background Technology

[0002] In the luggage industry, especially in the case of suitcases, users often face the problem of insufficient storage space. Traditional solutions mainly rely on increasing the volume of the case or adding fixed external pockets. However, the former results in a bulky case, while the latter is difficult to disassemble quickly and can damage the appearance of the case. Therefore, there is an urgent need for a solution that can both expand storage space and enable the quick assembly and disassembly of external expansion structures.

[0003] Patent document CN206150727U discloses an externally mounted trolley case, including a case body and a trolley rod. The trolley rod includes a main trolley rod and a telescopic rod, with a handle on the telescopic rod. The case body has recesses on both sides and the upper part of its back. The main trolley rod is installed in the recesses on both sides of the back. When the telescopic rod is retracted into the main trolley rod, the handle is located in the recess at the upper part of the back. By providing recesses on both sides and the upper part of the back of the case body, and placing the main trolley rod within these recesses, the distance between the two main trolley rods is increased compared to a traditional trolley case. This allows for more space inside the case when placing wider items, enabling it to hold more items. However, the increased storage space provided by this design is relatively limited.

[0037] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0038] This utility model discloses a trolley case with an external extension structure. Based on the synergistic effect of the groove formed by the pre-set base plate in the case shell and the external insert, the insert on the back of the external structure can be inserted into the groove and limited by the base plate, thereby realizing the quick assembly and disassembly of the external extension structure and the case body. Moreover, the fixed design of the base plate and the case body means that the external structure does not need to be perforated or have any protruding parts added to the case shell, thus maintaining the integrity and aesthetics of the case structure.

[0039] The trolley case with an external extension structure provided by this utility model, such as Figure 1 As shown, the device includes a suitcase body 1 and an external hanging structure 10, the external hanging structure 10 being detachably fixed to the side of the suitcase body 1; wherein the external hanging structure 10 includes a bag structure, such as... Figure 2 , Figure 3 As shown, the side of the suitcase body 1 is provided with a case shell groove 8 and a base plate. The base plate is fixedly installed on the suitcase body 1 and covers the groove opening of the case shell groove 8. In a preferred embodiment, the base plate and the suitcase body 1 are glued, screwed, sewn, or connected by a metal presser foot.

[0040] like Figure 4 , Figure 5 As shown, the side of the main body 10 of the external structure is provided with an external mounting plate 11 and an external webbing 12. One end of the external mounting plate 11 is fixedly installed on the main body 10 of the external structure, and the other end of the external mounting plate 11 is a free end for detachable connection with the external webbing 12. The opposite sides of the case recess 8 have sockets that match the external mounting plate 11 between them and the base plate. When the main body 10 of the external structure is fixed to the side of the trolley case body 1, the other end of the external mounting plate 11 is inserted into the case recess 8 from one socket and then led out from the other socket, and fixed with the external webbing 12. Through the synergistic effect of the base plate, the case recess 8 and the external mounting plate 11, the external mounting plate 11 on the back of the external structure can be inserted into the case recess 8 and limited by the base plate, thereby realizing the quick assembly and disassembly of the external expansion structure and the case.

[0041] In a preferred embodiment, a first magnetic snap 13 is installed on the external webbing 12, and a second magnetic snap 14 is installed on the other end of the external insert 11 for magnetic connection with the first magnetic snap 13. After the external insert 11 on the back of the bag slides into the recess 8 of the case, the magnetic snap automatically aligns and snaps in place. During disassembly, only the magnetic snap needs to be separated and the external insert 11 needs to be pulled out, without the need for tools, greatly simplifying the loading and unloading process. When the external structure is fixedly installed on the side of the suitcase body 1, the recess 8 of the case forms a physical limit on the external insert 11, effectively preventing lateral displacement or shaking of the external structure; the magnetic snap provides vertical attraction force to prevent accidental disengagement under bumpy conditions. The function of the external webbing 12 on the external insert 11 is to allow the magnetic snap to be relatively free and increase the fault tolerance of the magnetic snap, that is, when the magnetic snap on the back of the bag bulges, the magnetic snap can automatically align.

[0042] In a preferred embodiment, the upper and lower sidewalls of the recess 8 are both arc-shaped, extending from the edge of the recess 8 towards the center of the bottom of the recess 8, serving as the upper guide structure 7 and the lower guide structure 9, respectively. Through the arc-shaped guide structure, the external insert 11 slides naturally along the hyperboloid during insertion and withdrawal from the recess 8, significantly reducing frictional resistance. Simultaneously, this arc-shaped guide structure eliminates the risk of hard collision between the insert and the recess, extending the service life of the structure.

[0043] In a preferred embodiment, the side of the suitcase body 1 is provided with a first substrate mounting area and a second substrate mounting area. The case shell groove 8 is located in the first substrate mounting area, and the second substrate mounting area is a planar structure. Both the first and second substrate mounting areas are equipped with substrates, and the case shell groove 8 is located in the middle of the first substrate mounting area. In the first substrate mounting area, the two sides of the substrate are respectively fixedly mounted on the mounting portions on both sides of the case shell groove 8, and the middle part of the substrate covers the opening of the case shell groove 8. Both the first and second substrate mounting areas extend along the width direction of the suitcase body 1. The upper and lower sides of the case shell groove 8 have insertion slots that match the external mounting tabs 11 between them and the substrates. The first and second substrate mounting areas are spaced apart, such as... Figure 3 As shown, the side of the suitcase body 1 can be divided into a second substrate mounting area, a first substrate mounting area, a second substrate mounting area, a first substrate mounting area, and a second substrate mounting area from top to bottom, and a first substrate 2, a second substrate 3, a third substrate 4, a fourth substrate 5, and a fifth substrate 6 are fixedly installed thereon. The second substrate 3 and the fourth substrate 5 cover the groove 8 of the case shell and are used to limit and fix the external insert 11.
