Problems solved by technology

One downside of hard-sided luggage: they can be heavier than soft-sided luggage
However, soft-sided luggage is generally less durable and has lower support strength than hard-sided luggage, and their construction involves high labor input and material costs
Hybrid luggage that includes both hard and soft sides is lighter than hard-sided luggage, but is also less durable
For example, rolling a suitcase, especially a hard-sided suitcase, on a rough surface can cause vibration and noise and subject the suitcase to impact forces

Embodiment 1

[0051] Such as Figure 1~Figure 5 Shown: a luggage case, comprising a first shell 6 and a second shell 7, wherein the first shell 6 can be separated along a separation line and connected to the second shell 7 to define a storage space; A housing 6 is made of a curved metal plate. The metal plate is pivotally connected to the second housing 7 .

[0052] Specifically, the metal plate includes a first panel 1, a second panel 2, a plurality of hollow tubes 3 in the middle, and a brazing layer between the hollow tubes 3 and the first panel 1 and the second panel 2. The upper and lower sides of the hollow tubes 3 Each end is provided with a flanging 31, which turns out a circular structure. The flange 31 of the hollow tube 3 is connected to the first panel 1 and the second panel 2 by soldering 4 .

[0053] Both the first panel 1 and the second panel 2 are curved panels. The two ends of the hollow tube 3 are vertically connected with the contact surface of the panel. The line ty...

Embodiment 2

[0062] Such as Figure 6 Shown: The difference from Embodiment 1 is that both the first casing and the second casing are made of metal plates. Wherein, the first shell is made of a metal plate with a curved surface, and the structure of the metal plate is the same as that of the first embodiment. The second housing 7 is welded as a whole by four curved metal plates 71 . Because the second housing 7 has four corners, each corner part is a metal plate 71 with a curved surface; the metal plate 71 has a large arc, that is, a large central angle.

[0063] Frames 8 are provided on both sides between the panels, and the frame 8 is made of stainless steel, and the frame 8 is connected with the first panel 1 and the second panel 2 as a whole by brazing. The frame 8 is a semi-closed structure.

[0064] Others are with embodiment 1.

Embodiment 3

[0066] Such as Figure 7 Shown: a tool box, including a third housing 9 and a fourth housing 10, wherein the third housing 9 can be separated along a separation line and connected to the fourth housing 10 to define a storage space. Wherein the third housing 9 is made of a metal plate. The metal plate is pivotally connected to the fourth housing 10 .

[0067] The difference between this embodiment and Embodiment 1 is that the first panel and the second panel are both planar panels.

[0068] Other structures of the metal plate are the same as in Embodiment 1.

Abstract

A suitcase structure comprises a first casing and a second casing, wherein the first casing can be separated along a separation line and connected to the other casing to define a storage space; the suitcase structure is characterized in that the first casing and / or the second casing is formed by connecting one or more metal plates; each metal plate comprises a first face plate, a second face plateand a plurality of hollow pipes arranged between the first face plate and the second face plate, and a brazing layer is arranged between the hollow pipes and each of the first face plate and the second face plate; at least one end of each hollow pipe is provided with turnup. The suitcase structure has the advantages of being light in weight, durable, capable of absorbing impact force, keeping structural integrity under stress and reducing or minimizing vibration and / or noise and the like.

Description

technical field [0001] The invention relates to the field of luggage materials, in particular to a luggage structure. Background technique [0002] The shell of a hard-sided bag provides durability and support strength by using a formable, relatively stiff material to form its exterior. One downside of hard-sided luggage: they can be heavier than soft-sided luggage. However, soft-sided luggage is generally less durable and has lower support strength than hard-sided luggage, and their construction involves high labor input and material costs. Hybrid luggage, which includes both hard and soft-sided materials, is lighter than hard-sided luggage, but is also less durable. For example, rolling luggage, especially hard-sided luggage, on rough surfaces can cause vibrations and noise, and subject the luggage to impact forces. [0003] Accordingly, an improved luggage material is provided that is lightweight, durable, capable of absorbing impact, capable of maintaining structural ...
