Description

trunk

This creation is related to a storage compartment, especially a suitcase with impact resistance.

At present, the plastic hard-shell suitcases sold on the market are mostly formed by molding the base layer, but the surface after the molding is finished has irregularities, and the surface needs to be ground and then sprayed to form a smooth and bright Surface, this step is quite cumbersome and time consuming. Furthermore, the general hard-shell luggage has poor impact resistance, and the process of transportation during transportation is often deformed or cracked due to improper impact. Therefore, how to improve the above problems is an important issue.

The main purpose of this creation is to provide a suitcase that is impact resistant and extremely efficient to manufacture.

In order to achieve the above creation, the luggage of the present invention comprises a casing, a plurality of wheels and a handle member, characterized in that the casing has a base layer and a protective layer, the base layer is made of thermosetting polymer material (TS). The protective layer is made of a thermoplastic polymer material (TP) and coated on at least one side of the base layer.

Further, in the luggage case, the protective layer is disposed outside the base layer.

Further, in the luggage case, the casing has another protective layer, and the other protective layer is disposed inside the base layer.

Further, the luggage case, wherein the protective layer is also made of a thermoplastic polymer material (TP).

Further, the luggage case, wherein the thermosetting polymer material (TS) is epoxy resin or polyester.

Further, in the luggage case, the base layer contains carbon fibers.

Further, the luggage case, wherein the thermoplastic polymer material (TP) is at least one of the following groups: ABS, PP, PC, PE, TPU, PA.

Further, in the luggage case, the base layer is composed of a plurality of layer bodies.

The following describes the technical means and effects of the present invention in order to achieve the above objectives in conjunction with the drawings and the preferred embodiments of the present invention.

A first preferred embodiment of the present luggage case is shown in FIG. 1. The luggage case 1 includes a casing 2, a tie rod 3, a carrying handle 4, a latch 5, and a plurality of wheels 6. The casing 2 is the focus of reform.

The housing 2 of the present invention will be further described in detail below. As shown in FIGS. 2 to 3, the housing 2 is composed of a right half shell 2A and a left half shell 2B, and the housing 2 is zipper or the like. The structure is used as an opening or a combination, wherein each half shell has a base layer 22 and a protective layer 24, and the base layer 22 is a thermosetting polymer material (TS) which is incorporated into the thermosetting polymer material (TS). And being placed in a mold by pressure heating and vacuuming, the protective layer 24 is a thermoplastic polymer material (TP) and is disposed on the outer side 222 of the base layer 22, and the protective layer 24 is heated and pressurized and vacuumed. The base layer 22 is joined and fixed to the base layer 22 to form a protective film.

In the foregoing casing 2, the base layer 22 is actually constituted by a plurality of layers 221 of thermosetting polymer materials (TS). As shown in FIG. 4, the base layer 22 can be increased according to the size requirement of the trunk 1. The thickness is such that the base layer 22 conforms to the desired thickness of the casing 2 for the luggage 1 to provide better mechanical strength. In addition, the thermosetting polymer material (TS) may be epoxy resin (Epoxy), polyester (Polyester), the fiber may be glass fiber, carbon fiber, rayon, and the fiber may be uniaxial or braided. The base layer 22 of the thermoset polymer material (TS) provides the basic strength of the casing 2, while the protective layer 24 of the thermoplastic polymer material (TP) provides flexibility, thereby enhancing the ability of the casing 2 to be impacted on the one hand, On the one hand, the casing 2 can have good toughness, and it is easy to disperse the impact force, so that the trunk 1 is not easily broken and damaged to protect the internal articles.

In the aforementioned casing 2, the protective layer 24 is bonded to the base layer 22 by means of mold heating and pressing and vacuuming, and is disposed on the outer side 222 of the base layer 22 to form a smooth and shiny surface of the casing 2. The protective layer 24 is a thermoplastic polymer material (TP), and may be ABS resin (Acrylonitrile-Butadiene-Styrene, ABS for short), Polypropylene (PP), Polycarbonate (PC), Polyethylene (Polyethylene). , referred to as PE), Thermoplastic Polyurethane (TPU), Polyamide (PA) and its composite materials, have high tensile strength, strong wear resistance.

Through the above, the focus of the present work is that the base layer 22 formed by pressure heating and vacuuming in the mold can provide the basic strength of the casing 2, and the outer side 222 of the base layer 22 is covered via the protective layer 24 so that the casing 2 has It has better impact resistance and can be quickly produced.

A second preferred embodiment of the present luggage case is shown in FIG. 5, which emphasizes the complete protection effect inside and outside the luggage case 1 compared to the first preferred embodiment. The housing 2' has a base layer 22' and two protective layers. 24', the base layer 22' is a thermosetting polymer material (TS), which is incorporated into a thermosetting polymer material (TS) by a fiber, and is molded by heating and pressing and vacuuming, and each protective layer 24' For the thermoplastic polymer material (TP), since the base layer 22' has an outer side 222' and an inner side 224, the protective layers 24' are respectively disposed on the outer side 222' and the inner side 224 of the base layer 22' and are heated and pressurized and evacuated. The manner is joined to the base layer 22' and completely covers the outer side 222' and the inner side 224 of the base layer. The design of the two protective layers 24' protects the base layer 22' both internally and externally, making the housing 2' more impact resistant.

In the foregoing casing 2', the base layer 22' is actually constituted by a plurality of layers 221' of thermosetting polymer materials (TS), as shown in Fig. 6, which can be increased according to the size requirement of the trunk 1. The thickness of the base layer 22' is such that the base layer 22' conforms to the greater thickness required for the housing 2' to form the optimum mechanical strength of the luggage case 1. In this way, the thermosetting polymer material (TS) provides the basic strength of the casing 2', while the thermoplastic polymer material (TP) provides the flexural strength to strengthen the impact of the casing 2', so that the casing 2 'With good toughness, easy to disperse the impact of the impact, so that the trunk 1 is not easy to break, damage, to protect internal items.

In summary, the focus of this creation is on the design of the housing 2 (2'). The base layer 22 (22') is molded by a thermosetting polymer material (TS) by pressurized heating and vacuuming, and the protective layer 24 (24) ') is coated with a thermoplastic polymer material (TP) by bonding with the base layer 22 (22') to coat the outer side 222 (222') of the base layer 22 (22') or both inner and outer sides, thereby allowing the housing 2 (2') It is no longer necessary to produce by artificial replenishment as in the conventional technology, in other words, it can be mass-produced quickly, which is economical and is provided by the base layer 22 (22') and the protective layer 24 (24'). Perfectly composited, the luggage case 1 made of the present housing 2 (2') is particularly resistant to impact.

Finally, it must be explained again that the constituent elements disclosed in the foregoing embodiments are merely illustrative and are not intended to limit the scope of the present invention. Alternatives or variations of other equivalent elements should also be the scope of patent application of the present application. Covered.
