AI Technical Summary
Existing suitcases are ineffective at protecting the contents when subjected to impacts, lacking shock absorption and drop protection, which leads to damage to the items.
The honeycomb structure design, through the combination of surface layer, inner layer and reinforcing ribs, forms a cavity. The reinforcing ribs deform and absorb energy during impact, evenly distribute stress, and reduce the transmission of impact force to the inner layer.
It effectively buffers impact forces, avoids stress concentration, protects the items inside the box from damage, and has a simple, economical and practical structure.

Abstract
Description
[Technical Field]
[0001] This utility model mainly relates to an impact-resistant luggage structure. [Background Technology]
[0002] Suitcases are essential for travel, containing clothing and valuables. External impacts or drops can damage not only the suitcase itself but also the contents. Currently, most suitcases lack shock absorption and drop protection, focusing instead on enhancing their impact resistance. This makes it difficult to guarantee that items inside will remain undamaged during impacts. Therefore, we propose an impact-resistant suitcase structure. [Utility Model Content]
[0003] To address the issue of suitcases being lifted horizontally, this utility model proposes a novel structural solution. This impact-resistant suitcase structure employs the following technical solution:
[0004] An impact-resistant suitcase structure includes a suitcase body, which includes a surface layer and an inner layer. A cavity is provided between the surface layer and the inner layer, and reinforcing ribs are arranged in the cavity. The surface layer is connected to the inner layer as a whole through the reinforcing ribs. The surface layer under stress deforms in the cavity through the reinforcing ribs to buffer the impact and reduce the force transmitted to the inner layer.
[0005] Preferably, the inner layer has inwardly arranged stripes, with the stripes spaced apart.
[0006] Preferably, the surface layer is horizontal to the inner layer, and the surface layer is perpendicular to or inclined to the reinforcing ribs.
[0007] Preferably, the reinforcing rib includes a first rib and a second rib, which are intersected and connected.
[0008] The beneficial effects of this utility model compared with the prior art are:
[0009] In this structure, the outer and inner layers employ a porous design with reinforcing ribs within the cavities. The outer and inner layers are connected as a whole by these ribs, forming a honeycomb structure. Upon impact, this honeycomb structure absorbs energy through deformation. The honeycomb design ensures even stress distribution throughout the structure, preventing stress concentration. It boasts advantages such as simple structure, compact fit, and rational design; therefore, it is a product with superior technical and economic performance. [Attached Image Description]

Detailed Implementation Methods
[0013] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.
[0014] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0015] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0016] The preferred embodiment provided by this utility model is as follows: Figures 1-3 As shown, an impact-resistant suitcase structure includes a suitcase body made of ABS, PC, or a combination of both. The suitcase body includes a surface layer 1 and an inner layer 2. There is a cavity 3 between the surface layer 1 and the inner layer 2. Reinforcing ribs 4 are arranged inside the cavity 3. The surface layer 1 is connected to the inner layer 2 as a whole through the reinforcing ribs 4. The surface layer 1 under stress deforms in the cavity 3 through the reinforcing ribs 4 to buffer the impact and reduce the force transmitted to the inner layer 2.
[0017] The inner layer 2 is provided with inwardly arranged stripes, which are spaced apart; the reinforcing ribs 4 can be designed with single-strip spacing, or the reinforcing ribs 4 include a first rib 41 and a second rib 42, with the first rib 41 and the second rib 42 intersecting and connecting, or the first rib 41 and the second rib 42 are arranged in a figure-eight shape, which is taken as an example in this embodiment.
[0018] The surface layer 1 is horizontal to the inner layer 2, and the surface layer 1 is perpendicular to or inclined to the reinforcing rib 4, so as to increase the spacing between the surface layer 1 and the inner layer 2 and provide deformation space for the reinforcing rib 4.
[0019] In this structure, the outer layer 1 and inner layer 2 employ a void structure, with reinforcing ribs 4 set in the void cavity 3. The outer layer 1 and inner layer 2 are connected as a whole by the reinforcing ribs 4. The outer layer 1, inner layer 2, and reinforcing ribs 4 work together to form a honeycomb structure. When subjected to impact, the honeycomb structure can absorb energy through deformation. The honeycomb structure design allows stress to be evenly distributed throughout the structure, avoiding stress concentration problems. See also... Figure 2 In a localized area of the housing, the surface layer 1, inner layer 2, and reinforcing ribs 4 form a quadrilateral. When the surface layer 1 is compressed, the force is transmitted to the reinforcing ribs 4. After the reinforcing ribs 4 are deformed and compressed within the cavity 3, the weakened force is transmitted to the inner layer 2. At the same time, the stripes of the inner layer 2 can be further bent to reduce the force, thus achieving the effect of airway impact resistance.
