Description

Protective body for portable electronic products and manufacturing method thereof

This case relates to portable electronic products, especially a protective body applied to portable electronic products.

Portable electronic products are now very popular, especially mobile phones. As for the recent days, e-books and tablets have become popular. Because they are carried around, it is very important to protect the electronic products. of. Please refer to FIG. 1 , which is a schematic diagram of a protective case of a conventional technology. A protective case 1 is disclosed, which is divided into left and right parts by a bent portion 13, and an electronic article 2 is mounted on the right side, most of which is occupied by the screen 20, thereby being visible because the screen 20 is transparent, easily broken, and easy. It is wear and dirt, so it is necessary to protect the case 1 for protection. The portion of the protective casing 1 located to the left of the bent portion 13 can be covered on the screen 20 to provide protection. The bent portion 13 is present in order to open the protective case 1 as a book, but still can be kept in one piece, and in order to prevent the protective case 1 from being bent inward by the external force, the electronic article 2 is damaged. Inside the protective case 1 is a substrate 10 (shown by a broken line in Fig. 1), which is usually made of a hard material, and is disposed in the protective case 1 from left to right. In order to save weight and space, the bent portion is 13 is usually only composed of cloth 11 without the use of a hinge. The size of the cloth 11 is sufficient to cover two side-by-side substrates 10, and the cloth 11 is sandwiched between the front and the bottom of the substrate 10, and the cloth 11 is large to the center to retain a certain width so that the front and rear two pieces of fabric 11 can Direct contact, so that the center portion naturally forms a bent portion 13 due to the fact that the cloth 11 itself is suitable for the reverse bending property.

In order to allow the front and back two pieces of the cloth 11 to fix the substrate 10 therebetween, the cloth 11 extending outside the substrate 10 is directly joined to the front and back, and is usually ultrasonically coupled.

The cloth 11 is divided into a first fabric 111 attached to the first surface 101 and a second fabric 112 attached to the second surface 102. And the two fabrics (111, 112) are bonded to each other at the edge of the substrate 10 to form a closed portion 12, similar to the construction of the dumpling skin. It can be seen that there is no substrate 10 in the closed portion 12, that is, only the structure of the cloth is present, although a hard fabric is usually used, and since the closing portion 12 is usually ultrasonically coupled, it is closed. The material density and toughness of the portion 12 are relatively high, but after a long period of use, due to the pressing and collision, the closing portion 12 must have wrinkles, bends, buckling, etc., and in the severe case, the closed portion 12 The split, that is, the first fabric 111 and the second fabric 112 are separated from each other. Further, since the closing portion 12 is relatively thin, occasionally a condition of the user is cut.

It is damaged, easy to wear, and is easily soiled. Therefore, the protective body 3 is required as a protection. The portion of the protective body 3 located to the left of the bent portion 13 can be covered on the screen 20 to provide protection. The bent portion 13 is present in order to open the protective body 3 as a book, but still can be kept in one piece, and in order to prevent the protective body 3 from being bent inward by the external force, the electronic article 2 is damaged. In the protective body 3 is a substrate 10 (please cooperate with FIG. 4). Since the protective body 3 disclosed in FIG. 3 does not adopt the conventional closed portion 12 (see FIG. 2), the boundary of the substrate 10 is the protective body. The boundaries of 3 coincide. The substrate 10 is usually made of a hard material and is separated by the bent portion 13 to be disposed in the protective body 3 in a left-right manner. In order to save weight and space, the bent portion 13 is usually only made of the fabric 3'. Composition without the use of hinges. The fabric 3' is large enough to cover two side-by-side substrates 10, and the fabric 3' is a piece of the front and rear sheets sandwiching the substrate 10, and the fabric 11 is placed at a central position to retain a certain width for the front and rear two fabrics. 3' can be in direct contact, so that the central portion naturally forms a bent portion 13 due to the fact that the fabric 3' itself is suitable for the property of repeated bending.

Please refer to FIG. 4, which is a partial cross-sectional view of B-B of FIG. 1. The substrate 10 has a first surface 101 and a second surface 102, and the fabric 3' is further divided into a first fabric 31 attached to the first surface 101 and a second surface disposed on the second surface 102. The fabric 32 has a peripheral edge portion 31a which is folded over the edge of the substrate 10 and is bonded to the second surface, and the peripheral edge portion 31a is located between the substrate 10 and the second fabric 32. The second fabric 32 is bonded to the second surface 102 and the peripheral edge portion 31a of the substrate 10. In addition, in general, each fabric is permanently bonded to the substrate 10 by a thermal fusion technique. Therefore, a surface to be bonded to the substrate 10 on the first fabric 31 may form a hot melt adhesive layer or contain a hot melt adhesive.

Finally, the second fabric 32 and the substrate 10 are bonded. The second surface 102 and the peripheral edge portion 31a are thermocompression-bonded. Alternatively, the first surface 101 may be brought into contact with the first fabric 31, and then the peripheral edge portion 31a may be folded over to be in contact with the second surface 102. A fabric 31 and the first surface 101 simultaneously heat-press the second surface 102 and the peripheral edge portion 31a, and then the second fabric 32 is permanently bonded to the second surface 102 and the peripheral portion 31a through the hot press cooperation. . The thickness of each fabric in Figure 4 is only for the convenience of identification. In fact, the thickness of the fabric is a certain proportion thinner than the substrate.

5a to 5c are schematic views showing the manufacturing steps of an embodiment of the protective body of the present invention. First, please refer to FIG. 5a, in which a flat first fabric 31 is disclosed, and a peripheral portion 31a is formed at the periphery of the periphery, and a central portion is a bent portion 13, which divides the first fabric 31 into a substrate on the left and right sides. The adhesive portion 31b, that is, the portion enclosed by the dotted line in Fig. 5a. Next, as shown in FIG. 5b, after the substrate 10 is placed on the substrate adhering portion 31b, the peripheral portion 31a is folded over the edge of the substrate 10 to cover the substrate 10. As for the bent portion 13, the vacancy is maintained. Finally, referring to Fig. 5c, the second fabric 32 is placed on the substrate 10 and the peripheral portion 31a. Usually, the second fabric 32 is a whole piece of fabric from the left edge to the right edge of the protective body 3. Of course, for other considerations, the number of two or more sheets may be used. In addition, the steps regarding manufacturing are as described above and will not be described herein.

6a to 6c are schematic views showing the manufacturing steps of another embodiment of the protective body of the present invention. Looking at Figures 6a to 6c, the remainder is not substantially different from Figures 5a to 5c, the only difference being that the corners of the embodiment of Figures 6a to 6c are rounded, so that the first rounded fabric 31" has A rounded corner 31"R, and the peripheral edge portion 31a avoids the arc segment of the rounded corner 31"R until the portion of the straight line segment forms the peripheral edge portion 31a, so that the peripheral edge portion 31a is reversely contacted after the substrate 10 is disposed When the second surface 102 is reached (please cooperate with FIG. 4), unnecessary wrinkles are not generated due to the rounded corners 31"R of the circular arc design. It can be clearly seen from FIG. 6b that the peripheral portion 31a can be covered flatly. On the substrate 10, of course, the substrate 10 is also rounded with the same radius with the rounded corner 31"R. Finally, referring to Fig. 6c, the second fabric 32 is placed on the substrate 10 and the peripheral portion 31a (dotted line).

In summary, the "protective body of the portable electronic article and the manufacturing method thereof" of the present invention is to abandon the closed portion of the conventionally shaped dumpling-like food dough, because the closed portion forms a structure protruding from the substrate, This structure constitutes the edge of the protective casing of the conventional technique, but is bent and deformed due to the easy collision, and increases the size of the entire protective casing. Therefore, in the present invention, one of the two fabrics of the front and back sides is designed to have a peripheral portion structure, and the peripheral portion is folded from one side of the substrate to the other side of the substrate along the edge of the substrate, and covered by another fabric. The folded peripheral portion and the substrate, so that the structure such as the conventional closed portion is no longer needed, and therefore, when the side of the protective body of the present invention is subjected to pressing and collision, the external force can be directly received by the substrate without The phenomenon of bending, wrinkling, and even separation occurs like a conventional closed portion, and since there is no closed portion, the size of the protective body of the present invention can be made smaller, and there is no wrinkled closed portion after long-term use, and thus The appearance is beautiful. In addition, this case uses the hot pressing technology to improve the service life as much as possible, that is, to improve the durability, and the lowest temperature of the hot pressing in this case is one hundred degrees Celsius, and the highest temperature is one hundred and ninety degrees Celsius, that is, the temperature. The interval is from one bai to one hundred and ninety degrees Celsius. It can be seen that the present invention has a great contribution to the protection device for electronic products such as mobile phones or tablets that are carried around, and the manufacturing method of the protection device.
