Description

The present invention relates to the field of materials, and more particularly to a housing.

The present invention relates to the field of materials, and more particularly to a housing.

At present, the development of housings for mobile phones, electrical appliances, computers and the like has made great progress. In the prior art, the conventional housing is made of metal material or plastic. However, although the metal material is strong, it is heavy, it consumes precious metal resources and is not easy to carry. The plastic is thick and not strong enough, it is easily affected by the environment, and it may be loose, or it may be pressed to the internal circuit. Or parts. Apple 's patented "Reinforced Device Housing" uses multiple layers of carbon fiber or the same material used in the trunk and frame with carbon fiber. The use of outer frames or multi-layer materials ensures the strength of the fibers in different directions and solves the problem that carbon fibers are fragile at specific angles. The ultimate goal is to replace the oversized housing made of metal. However, mass production and cost can still be bottlenecks. Therefore, the iPhone 5 and iPad 3 are still not available as scheduled. The advantage of a shell retaining carbon fiber material overcomes the advantages of low production cost and mass production.

In view of the foregoing technical problems, it is an object of the present invention to provide a more robust and lightweight housing.

The object of the present invention is achieved by the following technical solution: a casing comprising: a composite fiber body, an elastic layer bonded to the composite fiber body, and a plastic body bonded to the elastic layer.

Further, the composite fibrous body is a thermosetting fibrous body or a thermoplastic fibrous body.

Further, the fibers in the composite fibrous body are long fibers or short fibers.

Further, the elastic layer comprises a thermoplastic elastomer.

Further, the thermoplastic elastomer comprises a polyurethane resin or a polyamide resin.

Further, the elastic layer comprises a thermoplastic elastomer and a hot melt colloid.

Further, the plastic body comprises a polyamide resin, an ABS resin, a polycarbonate resin, a PC/ABS resin, a polyamide resin mixed with glass fiber or carbon fiber, a polycarbonate resin, an ABS resin, a PC resin, a PC/ABS resin, and a PP. One or more of a resin or a polymethyl methacrylate resin.

Further, the composite fiber body, the elastic layer and the plastic body are combined in such a manner that the composite fiber body and the elastic layer are integrated by heating and pressurization, combined with the plastic body, or the composite fiber with the elastic layer added thereto The body and the plastic body to which the elastic layer is added are integrated by heating and pressurization.

Further, the number of layers of the elastic layer is a single layer, or the number of layers is a plurality of layers.

By using the technical solution of the present invention, it is possible to overcome the defects such as insufficient rigidity caused by using only plastic, and to save resources, and the housing is durable and light.

The present invention will be further described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , the present invention provides a casing comprising: a composite fiber body 1 , an elastic layer 2 bonded to the composite fiber body 1 , which is bonded to the elastic layer 2 Plastic body 3.

For example, the advantages of the housing of this structure, such as a mobile phone, the casing of the mobile phone is generally metal, the metal casing is too heavy, wastes resources, and is electrically conductive. Or the casing of the electrical appliance is a combination of a composite fibrous body and a plastic body. Generally, composite fiber bodies and plastic bodies take a long time to react and bond. There are also composite fiber bodies, but the disadvantage is that the success rate is small. It is a waste of time to cut the joints with a computer, and there are many raw edges. Therefore, the above disadvantages can be overcome by using a combination of three materials. The composite fiber body is sturdy and lightweight, and the plastic body can be combined to form a perfect shell. Such a casing can be used to manufacture a casing for 3C electrical products such as mobile phones, notebooks, etc., and to manufacture small accessories for sporting goods, such as pedals for bicycles, outsole for bicycles and other uses, and spare parts for motorcycles.

Further, the composite fibrous body 1 is a thermosetting fibrous body or a thermoplastic fibrous body.

Further, the fibers in the composite fibrous body 1 are long fibers or short fibers. Long fibers have better strength, and short fibers can be used for parts that do not require too high strength, and short fibers are less expensive than long fibers.

Further, the elastic layer 2 contains a thermoplastic elastomer. The thermoplastic elastomer is a rubber having elasticity at normal temperature and a plasticizable body at a high temperature.

Further, the thermoplastic elastomer comprises a polyurethane resin or a polyamide resin. Polyurethane resins have good oil resistance, toughness, abrasion resistance, aging resistance and adhesion. The polyamide resin has non-toxicity, light weight, excellent mechanical strength, wear resistance and good corrosion resistance.

Further, the elastic layer 2 comprises a thermoplastic elastomer and a hot melt colloid. The hot melt colloid can reinforce the thermoplastic elastomer. Can be applied to sports goods to increase the torsion resistance.

Further, the plastic body 3 comprises a polyamide resin, an ABS resin, a polycarbonate resin, a PC/ABS resin, a polyamide resin mixed with glass fibers or carbon fibers, a polycarbonate resin, an ABS resin, a PC resin, a PC/ABS resin, One or more of PP resin and polymethyl methacrylate resin. A polyamide resin mixed with glass fiber or carbon fiber is stronger than a polyamide resin and is resistant to high temperatures.

Further, the composite fiber body 1, the elastic layer 2 and the plastic body 3 are combined in such a manner that the composite fiber body 1 and the elastic layer 2 are integrated by heating and pressing, and then combined with the plastic body 3, and the bonding mode is suitable. The overall combination and manufacture of a relatively thin, small housing. Alternatively, the composite fibrous body 1 to which the elastic layer 2 is added and the plastic body 3 to which the elastic layer 2 is added are integrated by heating and pressurization. This method is more suitable for the manufacture of large finished parts.

The plastic body 3 in the above embodiment may be bonded, that is, combined with the elastic layer 2 by injection molding.

Further, the number of layers of the elastic layer 2 is a single layer, or the number of layers is a plurality of layers. The single layer will be lighter and thinner, and the multilayer will be stronger.
