Embodiment Construction

[0041] Such as Figure 4 to Figure 9D Shown, illustrate the embodiment of the luggage box body structure of the present invention and its manufacturing method.

[0042] A suitcase body structure provided by the present invention consists of a flat shell plate 20 which is folded and shaped to form a three-dimensional concave structure body 30 . The box body 30 can be selected from thermoplastic composite materials such as PVC (polyvinyl chloride), PP (polypropylene, Polypropylene) or PET (polyethylene terephthalate, Polyethylene terephthalate), woven into a single layer or The shell plate 20 of multi-layer structure is folded and shaped. Wherein, the manufacturing method steps of the casing 30 include:

[0043] A. Provide a rectangular flexible sheet made of thermoplastic composite material through weaving;

[0044] B. If Figure 8A As shown, four closed gaps 23 are provided adjacent to the plate and at positions equal to the vertical distance from the side of the plate;

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...
