[0028] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or components / elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0029] The following describes a method for forming a soft plastic protective case according to an embodiment of the present application in conjunction with the accompanying drawings.

[0030] Figure 1 is a schematic diagram of the structure of a soft rubber protective case provided by an embodiment of the present application. Figure 2 is an AA cross-sectional view of a soft rubber protective case provided by an embodiment of the present application, Figure 4 FIG. 1 is a rear view of a soft rubber protective case provided by an embodiment of the present application. Figure 1-2 and Figure 4 As shown: the soft glue protective shell includes a soft glue frame 1, an appearance protection layer 2 bonded to the inner end surface of the soft glue frame 1, and a removable glue layer 3 bonded to the inner side of the appearance protection layer 2.

[0031] According to an embodiment of the present application, the removable adhesive layer 3 is frame-shaped and is disposed at the edge of the appearance protection layer 2 .

[0032] According to an embodiment of the present application, a three-dimensional glue layer 8 is provided on the outer side of the soft glue frame 1 .

[0033] Specifically, the appearance protection layer 2 is bonded to the soft rubber frame 1 by glue, and then the appearance protection layer 2 is installed and fixed on the mobile phone, tablet, laptop and other products by the removable adhesive layer 3, replacing the buckle. In the past, it was installed by buckles, which were too tight. Nowadays, women love manicures, which are easy to hurt nails during installation and removal. Therefore, we adopt the gluing method, which is simpler to install and remove without hurting nails. In addition, the removable adhesive layer 3 is easy to stick and remove, and it is also convenient for users to replace it later.

[0034] like Figure 2 As shown, in one embodiment of the present application, the removable adhesive layer 3 is frame-shaped and does not need to cover the entire appearance protection layer 2. The bonding is sufficiently firm and easy to remove.

[0035] like Figure 4As shown, in one embodiment of the present application, the liquid soft glue can be used to drip the three-dimensional glue layer 8 onto the soft glue frame 1 of the solid soft glue through a glue dripping process using a mold, and then solidified into one piece. The production cost can be greatly reduced by making the three-dimensional glue layer 8 through the glue dripping process. At present, a set of molds only costs a few thousand yuan, while the traditional hard glue mold costs more than 50,000 yuan. In order to meet the needs of various customers in the market, the three-dimensional glue layer 8 needs to be designed with a variety of patterns to attract consumers, and this cost difference will be multiplied by dozens or hundreds of times. Similarly, in the design and production of the soft glue frame 1, the mold cost is also lower than the traditional one, and molds can be designed for different electronic device sizes.

[0036] It should be noted that the soft glue frame can be made of silicone or rubber, and the manufacturing processes of the two are similar. Among them, the silicone molding process is vulcanization and drip glue curing molding, which can be multi-color and multi-shape drip glue curing vulcanization molding, and can make a product appearance with a variety of colors and shapes to improve the aesthetics to meet the needs of users and consumers. Relatively speaking, rubber has better wear resistance and can be selected according to the performance requirements of specific users.

[0037] A soft rubber protective shell according to the present application is bonded with removable glue, which is easy to install and remove, and prevents damage to the user's nails; the design and manufacturing cost is low, and it is easy to adapt to the market with changing demands.

[0038] Figure 3 is an AA cross-sectional view of a soft rubber protective case provided by another embodiment of the present application. Figure 5 FIG. 1 is a rear view of a soft rubber protective case provided by another embodiment of the present application. Figure 1 , 3 As shown in 5: the removable adhesive layer 3 covers the entire appearance protection layer 2; a release film layer 5 is arranged on the inner side of the removable adhesive layer 3, and a graphene layer 6 is arranged on the inner side of the release film layer 5; a frame-shaped section 7 is arranged at the edges of the release film layer 5 and the graphene layer 6.

[0039] According to an embodiment of the present application, soft pads 9 are provided at the four outer corners of the soft rubber frame 1 .

[0040] Specifically, the release film layer 5 can be made of polyethylene glycolterephthalate (PET) material, and the release film layer 5 is used as an intermediate layer to connect the appearance protection layer 2 and the graphene layer 6, and the graphene layer 6 is bonded to the product. The graphene layer 6 is set on the release film layer 5 by a roll coating process. Since the frame-shaped section 7 separates the middle part and the edge part, when it is needed, the release film layer 5 at the edge is torn off, and the graphene layer 6 also falls off, exposing the inner frame-shaped removable adhesive layer 3, so that the product can be bonded.

[0041] Graphene has the function of conducting electricity and dissipating heat. Usually, mobile phones, tablets, notebooks and other electronic products will generate heat during use. We use graphite to dissipate heat.

[0042] Generally, the lower shell of an electronic device covers the processor, hard disk and other heat generating devices of the device, so a graphene layer 6 is required. When used as a lower shell, soft pads 9 can be provided at the four corners of the outer side of the soft rubber frame 1, so that the outer shell can still be placed stably without shaking or sliding.

[0043] It should be noted that the frame-shaped section 7 can be cut and formed on the release film layer 5 by a laser cutting process.

[0044] According to an embodiment of the present application, a glue groove 4 is provided on the inner end surface of the soft glue frame 1 , and adhesive is provided in the glue groove 4 , and the appearance protection layer 2 is bonded by the adhesive.

[0045] Specifically, glue can be applied on the inner end surface of the soft glue frame 1 to bond the appearance protection layer 2, but the glue is easy to flow to the outside during production, affecting the product appearance. In order to solve this problem, a glue groove 4 can be provided so that the glue will not flow to the side, thereby improving product quality.

[0046] Figure 6 is an AA cross-sectional view of a soft rubber protective case provided by another embodiment of the present application, such as Figure 6 As shown: a graphene layer 6 is provided between the removable adhesive layer 3 and the appearance protection layer 2 .

[0047] Specifically, in addition to the basic anti-scratch protection, the graphene layer 6 can be rolled to improve the heat dissipation performance of the protective shell. This technical solution can be used in the design of the upper shell and the lower shell, and when used as the lower shell, the overall production cost is low.

[0048] According to one embodiment of the present application, the cross-section of the soft rubber frame 1 is L-shaped.

[0049] Specifically, the L-shaped soft rubber frame 1 can cover the side of the electronic device housing, and the front is covered by part of the soft rubber frame 1 and the appearance protection layer 2, thereby completely covering the exposed end face of the housing. Moreover, the soft rubber frame 1 is made of a relatively soft material, and when a collision occurs, it is generally the side frame that is hit. The soft rubber frame 1 can play a buffering role and better protect the device. In addition, when the front falls, since the L-shaped frame on both sides forms a raised platform, the front fall impact is also buffered and protected by the soft rubber frame 1.

[0050] According to an embodiment of the present application, the appearance protection layer 2 is one of transparent film, leather, cloth, microfiber synthetic leather, laser pattern or printed pattern.

[0051] Specifically, according to customer requirements, the surface appearance layer can be made of transparent film as a protective layer, or can be made of high-grade genuine leather, or can be made of ultra-fine fiber synthetic leather, commonly known as ultra-fine fiber, also known as split cowhide. In addition to leather, cloth can also be used, such as non-woven fabric or horsehair cloth. In addition, laser patterns or printed patterns can also be used, so that the appearance protection layer 2 can be easily printed with various patterns in addition to the basic protective function.

[0052] It should be noted that the transparent film can be made of transparent frosted or mirrored materials such as PET, PC (polycarbonate), PETG (polyethylene terephthalate), APET (amorphous polyethylene terephthalate), TPU (thermoplastic polyurethane), etc. These materials are low in cost and high in hardness, and can play a good role in scratch resistance.

[0053] Figure 7 FIG. 1 is a rear view of a soft rubber protective case provided by another embodiment of the present application. Figure 7 As shown: the appearance protection layer 2 is provided with a plurality of heat dissipation grooves 10.

[0054] Specifically, when the protective shell is used as the lower cover, if there are holes for exhaust and heat dissipation in the corresponding device, a row of corresponding heat dissipation grooves 10 can be cut out by die stamping at the appearance protective layer 2 of the protective shell.

[0055] It should be noted that, in some embodiments, a release film layer 5 and a graphene layer 6 are provided on the inner side of the appearance protection layer 2 , which can be stamped together with the appearance protection layer 2 .

[0056] Example 1: Figure 1 , 2 As shown in Figures 4 and 5, the design is a protective cover for the upper cover of a tablet computer. The soft glue frame 1 with an L-shaped cross-section protects the frame of the upper cover of the tablet computer; the appearance protection layer 2 is made of APET material with a frosted design. The material has a high hardness and good scratch resistance; the appearance protection layer 2 is bonded to the soft glue frame 1 through the glue in the glue groove; the removable glue layer 3 at the appearance protection layer 2 is used to bond the end face of the upper cover of the tablet computer. A three-dimensional glue layer 8 is fixed to the soft glue frame 1 on the back (also called the front for the upper cover). In this embodiment, the three-dimensional glue layer 8 includes a trademark and a three-dimensional pattern next to it.

[0057] Example 2: Figure 1 , 3 As shown in FIG. 5 , the design is a lower cover protective cover for a tablet computer. The soft rubber frame 1 with an L-shaped cross-section protects the frame of the lower cover of the tablet computer; the appearance protection layer 2 is made of leather and is bonded to the soft rubber frame 1 by glue in the glue groove; a release film layer 5 made of PET material is provided on the inner side of the appearance protection layer 2, and a graphene layer 6 is rolled on the inner side of the release film layer 5. It should be noted that Figure 3 It is a structural diagram. The actual product of the graphene layer 6, the release film layer 5, the removable adhesive layer 3 and the appearance protection layer 2 is very thin. The stacked thickness of the graphene layer 6, the release film layer 5 and the removable adhesive layer 3 is approximately equivalent to the thickness of the double-sided tape. Therefore, it will not affect the heat dissipation of the device due to being too thick.

[0058] Example 3: Figure 1 , 5 As shown in Figure 6, the design is a lower cover protective cover for a tablet computer. The soft rubber frame 1 with an L-shaped cross-section protects the frame of the lower cover of the tablet computer; the appearance protection layer 2 is made of APET material, with a frosted design and good scratch resistance; the appearance protection layer 2 is bonded to the soft rubber frame 1 by glue in the glue groove; the inner side of the appearance protection layer 2 is roll-coated with a graphene layer 6, and the inner side of the graphene layer 6 is provided with a removable glue layer 3 for bonding the end face of the lower cover of the tablet computer, and the removable glue layer 3 is frame-shaped, which is easy to load and unload.

[0059] The above embodiments are preferred implementation schemes of the present application. In addition, the present application may also be implemented in other ways. Any obvious replacement without departing from the concept of the present application is within the protection scope of the present application.
