Luggage box body structure and its manufacturing method

Abstract

The invention provides a luggage box body structure and a manufacturing method thereof, wherein the luggage box body structure is a stereoscopic box body being made from a woven thermoplastic composite material. The box body includes four side plates, a bottom plate and four arc-angle end parts, wherein a sealed arc-shaped gap is formed at an adjacent connection position of each arc-angle end part and the bottom plate. Any two adjacent connection side plates are each integratedly extended to form a first laminated part and a second laminated part, wherein an integrated connection structure being free of notch is formed between the first laminated part and the second laminated part. The arc-angle end parts of the box body are folded and are attached to the first laminated part and a second laminated part and are arranged on an inner surface of one side surface to form an integratedly connected and laminated angle end structure. By means of the folding method, the plate material, of which the angle ends are not notched, are folded and are processed to form a stereoscopic concave box body structure, thereby achieving the object of increasing the strength of the angle end parts of the box body without increasing of the whole weight of the luggage box.

Description

technical field [0001] The present invention relates to a hard suitcase, in particular to the box structure of the hard suitcase and the shell plate structure and manufacturing method of the box. Background technique [0002] At present, suitcases can be mainly divided into soft suitcases made of flexible materials and hard suitcases made of hard plastics according to the material of the casing. Among them, since hard luggage has better resistance to deformation, it can provide better protection for the contents than soft luggage. However, the existing hard suitcases are limited by the material and often lack attractiveness in appearance and touch, and it is difficult to reduce the weight of the suitcase body. [0003] With the advancement of materials science, such as Figure 1 to Figure 3 As shown, there are currently relevant operators who use thermoplastic composite materials to weave a flexible rectangular plate 10, and form four incisions 11 by removing the four corne...

AI Technical Summary

Problems solved by technology

However, when the existing luggage case A is in actual use, since the plate 10 is provided with the four cutouts 11, the ends of the four side panels of the luggage case A box body 100 are in a separated state, although the rigid protection member 13 Combined with protection, there is still the problem of insufficient structural strength in essence, so, if figure 1 As shown, the above-mentioned box body 100 with notches 11 at the corner ends of the panels 10 can only supplement the overall structural strength of the suitcase A by increasing the covering area of ​​the rigid protection member 13, but at the same time, it also extends the problem of increasing the overall weight of the suitcase A.
