Detailed Description

To explain the technical content, the structural features, the achieved objects and the effects of the invention in detail, the following detailed description is made with reference to the embodiments and accompanying drawings, wherein the "up" and "down" positional relationships in the present specification correspond to the up and down directions in fig. 1, respectively.

Fig. 1 shows a first embodiment of the present invention, and an electronic product protective case based on 3D printing includes a case 1, where the case 1 includes a bottom surface and a side surface formed around the bottom surface. In the present embodiment, the protective case is integrally formed by 3D printing. Optionally, the inner layer of the protective shell is a continuous enveloping surface, and the outer side of the protective shell is a hollowed-out buffering surface, or the inner layer of the protective shell can also be a hollowed-out surface, and the inner side surface contacting with an electronic product can also be an uneven surface. For convenience of description, the inner layer and the outer layer of the housing 1 will be described as the inner housing 11 and the buffer layer 12, respectively, i.e., the housing 1 is composed of the inner housing 11 and the buffer layer 12.

The buffer layer is actually a hollow elastic buffer structure formed by a plurality of 3-dimensional structure lines, and the repeating units of the 3-dimensional structure can adopt various three-dimensional structures, which is not limited in the structure shown in the figure. As shown in fig. 2, the buffer layer 12 is formed by overlapping a plurality of hollow three-dimensional structural ribs 122; the gaps between the hollow three-dimensional structure ribs 122 and the three-dimensional structure ribs 122 form a surface layer similar to an air cushion, so that the shock-proof structure has a good shock-proof effect, and the electronic product can be effectively prevented from being broken. The buffer layer 12 is thickened at four corners of the shell 1 to form elastic ear portions 121 protruding from the rest of the outer surface, and the elastic ear portions 121 may protrude only from the side surfaces of the shell 1 as shown in fig. 1, or protrude from both the side surfaces and the bottom surface of the shell.

An accommodating space 111 for accommodating an electronic product is arranged in the inner shell 11; the bottom surface of the shell 1 is provided with a camera hole 14 matched with a camera of an electronic product; the side of the housing 1 is further provided with a plurality of functional holes 13, including a volume key hole 131 matched with a volume key of an electronic product, a power key hole 132 matched with a power key, an external hole 133 matched with an external music port, a power interface hole 134 matched with a power interface of the electronic product, and an earphone hole 135 matched with an earphone interface.

The inner shell 11 and the buffer layer 12 are made of photosensitive resin materials and are integrally formed based on 3D printing. The photosensitive resin material can be acrylic epoxy resin, unsaturated polyester, polyurethane or polythiol/polyene photocuring resin. The materials have good elasticity and flexibility, and can play a good role in buffering and protecting electronic products when the electronic products are impacted by external force.

During the use, with the electronic product prevent including the accommodation space 111 in 11 shells, 11 parcels in the shell are outside at the electronic product, and when the electronic product dropped, the cladding had certain elasticity at 11 outside buffer layer 12 in the shell, especially the elasticity ear 121 of 1 four corners thickening in the shell, had protected the electronic product, prevented that vibrations from breaking. This elasticity ear 121 outwards protrusion in the side of casing 1, can touch ground earlier and form the strong point when electronic product falls to the ground, optionally, this elasticity ear still downwards protrusion in the bottom surface of casing, when electronic product places on horizontal planes such as desktop, elasticity ear supports casing and electronic product as the impetus.

In the present embodiment, the positions of the camera hole 14, the volume key hole 131, the power key hole 132, the external hole 133, the power interface hole 134, and the earphone hole 135 are merely illustrative, and the positions do not limit the scope of the present invention.

The present invention is also a second embodiment in addition to the above embodiments, and the present embodiment is different from the above embodiments in that: the inner shell 11 is formed by compression molding, and the buffer layer 12 is formed on the outer side of the inner shell 11 by photosensitive resin materials based on 3D printing; therefore, the 3D printing forming time is reduced, and the material cost is also reduced.

According to the two embodiments of the invention, the buffer layer 12 with four thickened corners is additionally arranged on the outer side of the protective shell, so that the electronic product in the protective shell is effectively prevented from being broken; adopt 3D printing technology processing, can produce the protective housing of different models fast, improve production efficiency, the product is more pleasing to the eye durable.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the foregoing description only for the purpose of illustrating the principles of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims, specification, and equivalents thereof.
