Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Referring to fig. 1 to 4, the soft case 10 of the base-less mobile phone includes a bottom 11 and a side 12 surrounding the bottom 11, where the side 12 is a double-layer structure formed by gluing a second surface layer 121 and a second inner layer 122, and further, an inner layer is glued on the inner side of the bottom 11, so that the bottom 11 is also a double-layer structure, that is, the bottom 11 is formed by a first surface layer 111 and a first inner layer 112, a rigid filament is clamped between the double-layer structures of the side 12 at the mouth of the soft case, and the rigid filament is connected end to form an annular skeleton 14 for supporting and maintaining the shape of the mouth.

Referring to fig. 3, the soft cover 10 of the base-less mobile phone is made of two pieces of cloth, one piece of cloth forms the first surface layer 111, the second surface layer 121 and the second inner layer 122, and the other piece of cloth forms the first inner layer 112.

In the present application, the bottom 11 of the soft shell 10 may also be a single layer structure. In this embodiment, the bottom portion 11 and the side portion 12 are made of the same sheet material.

The sheet material constituting the bottom portion 11 and the side portion 12 is a cloth. But leather or other similar materials may also be used in the present application.

Further, the rigid filaments are steel wires covered with rubber sleeves. The gum cover plays the effect of preventing the steel wire from rusting on the one hand, and on the other hand makes annular skeleton 14 produce little shrink, more does benefit to imbedding the cell-phone in this soft shell.

Referring to fig. 5, the base-material-free mobile phone soft shell 10 further has a camera hole 13 formed in the bottom 11, and an edge 15 is clamped at the edge of the camera hole 13. The edge 15 serves, on the one hand, for decoration and, on the other hand, for preventing thread detachment. The tipping 15 is preferably a metal sheet.

Referring to fig. 6, a forming process of the soft shell 10 of the base-material-free mobile phone includes the following steps:

and step S1, cutting. Cutting the cloth by adopting modes of punching, laser cutting and the like to obtain the fabric and the lining, wherein the size of the fabric is larger than the sum of the size of the bottom 11 of the shell and the size of the double side 12, and the size of the lining is the same as or slightly smaller than the size of the bottom 11 of the shell.

And step S2, coating the fabric with glue. And a hot-melt film is fused on the back side of the fabric. Specifically, the cut fabric is placed into a positioning die, a hot melt film and a PC sheet are sequentially placed into a film cavity of the positioning die, and then the fabric covered with the hot melt film and the PC sheet is heated to melt the hot melt film. The PC sheet is used as a process sheet to prevent the cloth from sticking together when subjected to high temperature, and is taken out after molding.

And step S3, stretching and forming. The structure of the drawing die 20 is shown in fig. 7, and includes an outer die 21 and an inner die 22, the outer die 21 having a cavity 211 in the middle. The specific stretch forming method comprises the following steps: putting the fabric on an outer die 21 of a stretching die 20, pushing an inner die 22 of the stretching die 20 placed above the fabric downwards into a cavity 211 in the middle of the outer die 21, so that the middle of the fabric moves downwards to stretch the fabric into a first semi-finished product with a bottom part 11 and a side part 12, cooling and shaping, and removing the stretching die 20 to obtain the first semi-finished product.

And step S4, embedding the annular framework 14. The ring-shaped frame is matched with the shape and size of the mouth of the soft shell 10 of the base-material-free mobile phone as shown in fig. 4, and is used for supporting and maintaining the shape of the mouth of the soft shell 10 of the base-material-free mobile phone.

Two dies, one of which is a core die 30 as shown in fig. 8 and the other of which is a push edge die 40 as shown in fig. 9, are used in the step of fitting the ring frame 14. Referring to fig. 8, the core mold 30 is formed by abutting a left mold part 31 and a right mold part 32, and the upper end of the core mold 30 has a lower recess 33 for positioning the ring frame 14. Referring to fig. 9, the push mold 40 includes an upper mold portion 43 and a lower mold portion 41, the lower mold portion 41 is capable of being received in the core mold 30 and clamping a side portion of the first semi-finished product in cooperation with the side portion of the core mold 30, the upper mold portion 43 is slightly smaller than the lower mold portion 41, and an inner recess 42 is formed at a connection portion of the upper mold portion 43 and the lower mold portion 41 for receiving the ring frame 14.

The specific method for embedding the annular framework 14 comprises the following steps: embedding a core mould 30 in the first semi-finished product, placing an annular framework 14 at the upper end of the core mould 30, pushing the edge of the first semi-finished product to fold inwards to wrap the annular framework 14 by using a side pushing mould 40, clamping between the core mould 30 and the side pushing mould 40, heating at high temperature, finishing and flattening the edge, cooling and shaping, and taking out the side pushing mould 40 and the core mould 30 to obtain a second semi-finished product with a shaped opening and embedded with the annular framework 14.

And step S5, gluing. And folding the edge of the second semi-finished product inwards by using the edge-pushing mould 40, heating at high temperature to melt the hot-melt adhesive sheet on the back side of the fabric, extruding to glue the two layers of folded fabric, cooling and shaping, and taking out the edge-pushing mould 40 to obtain a third semi-finished product of the side part 12 with the double-layer structure.

And step S6, punching edges. And (4) putting the third semi-finished product into a punching die, and removing the redundant part of the fabric by punching. The PC sheet was then peeled off.

And step S7, drying. Drying in a drier.

And step S8, gluing the lining. And pressing a hot melt adhesive sheet on the back side of the lining, then putting the lining pressed with the hot melt adhesive sheet into the non-base material soft shell processed in the step S7, and carrying out hot pressing to melt the hot melt adhesive sheet so as to glue the lining and the surface material to form the bottom 11 with the double-layer structure.

And step S9, opening the camera hole 13 to obtain the final soft shell without the base material. The openings are preferably laser cut.

The cooling in the above process is carried out in ice water.

It can be seen that the final soft cover of the handset is obtained without any rigid plate for supporting, that is, a soft cover 10 of a cloth material without a base material is obtained.

It is understood that the non-base material soft shell 10 can be made of leather or other similar materials by the above process, and that the above process can be used to form not only the soft shell of the mobile phone, but also any soft shell composed of a bottom 11 and four sides 12.

The present invention has been described in detail with reference to the specific embodiments, and the detailed description is only for assisting the skilled person in understanding the content of the present invention, and can not be understood as the limitation of the protection scope of the present invention. Various decorations, equivalent changes and the like which are performed on the scheme by the technical personnel in the field under the conception of the invention are all included in the protection scope of the invention.
