Mobile phone back cover protection patch structure

This creation is a mobile phone back cover protection patch structure, especially one that protects the back cover of the mobile phone from scratching and abrasion.

According to the modern people, the use of portable electronic devices such as mobile phones, tablets or personal digital processing devices (PDAs) has become more and more popular, and it is almost inseparable from life. Therefore, people are concerned about such portable electronic devices. Protection requirements are more important. In the foregoing portable electronic device, taking a mobile phone as an example, in the course of use, there is often an unavoidable cause of damage to the mobile phone, for example, the appearance is broken due to dropping or as shown in FIG. 1 The back cover 2 wears and scratches, so in order to avoid the damage of the mobile phone 1, the mobile phone 1 usually has a protective sticker attached to the screen, and the outer casing is sleeved with a protective cover to protect the appearance of the mobile phone. Free of damage; however, the modern mobile phone 1 is based on the demand for thinning. After the protective cover of the mobile phone is set, the grip is thicker, and the appearance of the original bare-metal design is lost due to the shielding of the protective cover. At the same time, it also causes the problem that the mobile phone 1 and the protective cover are not integrated and different styles.

The main purpose of the present invention is to solve the above problems, and to provide a mobile phone back cover protection patch structure, the main technology and purpose is: attaching a protective layer of a glass layer as a base material on the back cover of the mobile phone, the glass layer The printing layer is provided on the side, and the printing layer can be printed according to the user's requirements. It has a decorative print pattern that protects the back cover of the phone and has a thin grip.

According to the above object of the present invention, a mobile phone back cover protection patch structure comprises: a glass layer; a printing layer disposed on one side of the glass layer; and a high adhesive adhesive layer disposed on the printing layer facing away from the a transparent substrate disposed on a side of the high-viscosity adhesive layer facing away from the printed layer; and a low-viscosity adhesive layer disposed on the transparent substrate facing away from the high-viscosity adhesive layer The side of the protective patch has a curved arc that conforms to the edge of the back cover.

In an embodiment of the present invention, the protection patch is provided with at least one hollowed out area.

In an embodiment of the present invention, the printed layer may be a printed pattern of a pattern, a graphic, a line, a web, a text, or a stereo image.

In an embodiment of the present invention, the transparent substrate is made of a material of polyethylene terephthalate (PET), and the high-viscosity adhesive layer is made of OCA optical glue or acrylic. The low-viscosity adhesive layer is made of silicone.

With the above structure, the back cover of the mobile phone can be protected, and the grip feeling of thinning can be achieved, and the aesthetic design can be revealed.

In order to make the reviewer have a better understanding of the creation, a preferred embodiment is shown in conjunction with the drawings, as detailed below: please refer to Figures 2 and 3, including: a glass layer 11; a printed layer 12, set a side of the glass layer 11; a high-adhesive layer 13 disposed on a side of the printing layer 12 facing away from the glass layer 11; a transparent substrate 14 disposed on the high-adhesive layer 13 away from the printing a side of the layer 12; and a low-adhesive layer 15 disposed on a side of the transparent substrate 14 facing away from the high-adhesive layer 13; the edge of the protective sheet 10 is provided with a curved surface conforming to the edge of the back cover 4 bending the arc segment 16, and the protective patch 10 is provided with at least one hollowed out region 17; by the above structure, the back cover of the mobile phone can be protected, and the grip feeling of the thinning can be obtained, and the aesthetic design feeling can be revealed; At the same time, the printed layer 12 can print decorative patterns such as decorative patterns, graphics, lines, textures, characters or stereoscopic images according to user requirements.

The composition and function of the above embodiment are described in detail as follows: Referring to Figures 2 to 3, in the present embodiment, the transparent substrate 14 of the protective patch 10 is made of polyethylene terephthalate (PET). The high-viscosity adhesive layer 13 is made of high transparency OCA optical adhesive and acrylic, and the low-viscosity adhesive layer 15 is made of high transparency silicone; When the protective cover 10 is covered on the back cover 2 of the mobile phone 1, first, the protective patch 10 is adjacent to the top of the mobile phone 1. The hollowed out area 17 corresponds to the camera lens 3 of the mobile phone 1, the brand logo or other functions of the mobile phone 1. The protective portion 10 can be exposed through the protective patch 10 to be unobstructed, and then slowly lowered to adhere the protective patch 10 to the back cover 2 of the mobile phone 1 to complete the bonding action of the protective patch 10; The curved section 16 is wrapped on the curved surface 4 of the edge of the back cover 2 (as shown in FIG. 3), and the protective patch 10 is not easily touched and flipped off, so that the back cover 2 is Not directly affected by impact or friction. Furthermore, the printed layer 12 can be formed into various patterns and colors with different pigments to present a translucent or opaque quality. Sense, used to decorate the phone 1 back cover 2 to express different styles, or as a publicity, advertising effect, to achieve a variety of variability.

According to the above technical means, the present invention can also be implemented in another embodiment shown in FIG. 4. The protective patch 20 comprises: a glass layer 21; an adhesive layer 22 disposed on the glass layer 21. One side; an explosion-proof layer 23 disposed on a side of the adhesive layer 22 facing away from the glass layer 21; a printed layer 24 disposed on a side of the explosion-proof layer 23 facing away from the adhesive layer 22; a high-viscosity adhesive a layer 25 disposed on a side of the printed layer 24 facing away from the explosion-proof layer 23; a transparent substrate 26 disposed on a side of the high-viscosity adhesive layer 25 facing away from the printed layer 24; and a low-viscosity adhesive layer 27 And disposed on a side of the transparent substrate 26 facing away from the high-adhesive adhesive layer 25; the edge of the protective patch 20 is provided with a curved portion 28 conforming to the curved surface of the back cover edge, and the protective patch 20 is provided At least one hollowed out area 29.
