Description

Luggage box structure and its preparation method

The present invention relates to a rigid luggage case, and more particularly to a box structure of a rigid luggage case and a structure and a method of manufacturing the same.

At present, the trunk can be mainly divided into a soft suitcase made of flexible material and a hard suitcase made of hard plastic depending on the material of the box. Among them, because the hard luggage has better resistance to deformation, the softer luggage can provide better protection of the contents. However, conventional hard luggage is limited in material and often lacks the appeal of appearance and touch, and it is difficult to reduce the weight of the trunk body.

With the advancement of materials science, as shown in Figures 1 to 3, there are currently related companies that use a thermoplastic composite material to woven into a flexible rectangular sheet 10, and four slits 11 are formed by removing the four corner ends of the sheet 10. Then, the four side edges 12 of the plate 10 are folded up to combine the two side edges 111 of the slit 11 to form the three-dimensional concave box 100, and finally formed by thermoforming or molding. A lightweight and high structural strength luggage case A 100 is made from a thermoplastic composite.

As shown in Figures 1 to 3, the side edge 111 of the slit 11 of the aforementioned sheet material 10 is mainly By providing the assembly holes 112, the rigid protection members 13 are assembled to the assembly holes 112 for the purpose of bonding and fixing the side edges 111 of the slits 11. However, in the actual use of the trunk A, since the plate 10 is provided with the four slits 11, the four side plate ends of the trunk A case 100 are separated from each other, although the rigid protective member 13 is combined. Protection, but there is still a problem of insufficient structural strength in essence, that is, as shown in Fig. 1, the casing 100 provided with the slit 11 at the corner end of the plate 10 can only be complemented by increasing the covering area of the rigid protective member 13. The overall structural strength of the trunk A also extends the problem of increasing the overall weight of the trunk A.

The object of the present invention is to provide a trunk box structure and a manufacturing method thereof, which mainly utilizes a folding means to fold and process a sheet material having no slit at a corner end into a three-dimensional concave box structure, thereby effectively improving the corner end portion of the box body. Structural strength without significantly increasing the overall weight of the luggage.

The foregoing luggage case structure of the present invention is folded and molded by a shell plate. The shell plate has four sides and four corner ends connecting the four sides, and the shell plate is provided with the four closed arc-shaped notches adjacent to the four corner ends, wherein the corner ends are Between the notch and the two adjacent sides thereof, one first fold line and one auxiliary line are formed equal to each other and are perpendicular to each other, and a second fold line is disposed between the notch and the sharp point of the corner end.

Further, the method for manufacturing the foregoing shell plate into a box comprises: providing a rectangular flexible sheet material obtained by braiding a thermoplastic composite material; and adjacent to the sheet material and being equidistant from a side of the sheet material Providing four closed shape notches; a first fold line and an auxiliary line are disposed from the notch to the side of the sheet, and a second fold line is disposed from the notch to the corner end of the sheet; folding the four corner ends of the sheet to The region between the first fold line and the second fold line and the area between the auxiliary line and the second fold line are overlapped to form a single body; the sheet body is placed in close contact with the inner surface of the sheet material, and the sheet material is formed into four pieces. The three-dimensional concave structure formed by the side plate and the bottom plate; the three-dimensional concave structure is formed by the press molding process to have a luggage case body integrally connected with the stacked corner end structure.

Preferably, in the foregoing luggage box structure and the manufacturing method thereof, the overlapping structure of the first overlapping portion and the second overlapping portion is defined as a thickening piece, and the four thickening pieces of the box body may be reversed The hour hand or the clockwise direction is attached to the inner surface of the side plate of the box, or the four side plates defining the box are two relatively short side plates and two relatively long side plates, and the four thick plates of the box can be along the two short side plates. Or attached to the inner surface of the side plate along the two long side plates, and the structural strength of the end portion of the arc angle of the box is increased through the thickened piece.

Preferably, in the foregoing luggage box structure and the manufacturing method thereof, the first overlapping portion and the second overlapping portion of each of the arcuate end portions of the box body can be matched by directly bonding or fixing corresponding positions of the perforations. The appropriate fixing parts are placed and fixed to ensure the overlapping of the first overlapping portion and the second overlapping portion.
