Detailed Description

Examples of the present application are described in detail below and are illustrated in the accompanying drawings. The examples described below with reference to the drawings are illustrative and intended to be used for explaining the present application and are not to be construed as limiting the present application.

In one aspect of the present application, a protective case is presented. According to some examples of the present application, referring to fig. 1 and 2 (fig. 2 is a schematic cross-sectional structural view of the protective case along direction AA' in fig. 1), the protective case 100 has a main body portion 110, a sidewall portion 120, and an anti-fouling coating 140, wherein the main body portion 110 has a first face 11 and a second face 12 disposed opposite to each other, the sidewall portion 120 is disposed around the main body portion 110, the sidewall portion 120 defines an electronic-device accommodating space 130 on a side of the second face 12 of the main body portion 110 away from the first face 11, and the anti-fouling coating 140 is disposed on a surface of the sidewall portion 120 on a side away from the electronic-device accommodating space 130, wherein a material forming the sidewall portion 120 includes a. Therefore, the anti-fouling coating 140 can better protect the side wall portion 120, improve the anti-fouling and anti-yellowing performance of the side wall portion 120, and the protective shell 100 has good service performance.

In addition, the "main body portion 110" of the protective case 100 described above, which is shown in fig. 1 and 2, is a portion corresponding to the protective case 100 and a battery cover (back cover) of an electronic device (not shown in the drawings), for example, the main body portion 100 may have a rectangular planar structure; the aforementioned "side wall portion 120" of the protective casing 100 is shown in fig. 1 and fig. 2, and is a portion corresponding to the protective casing 100 and a middle frame of an electronic device (not shown in the drawings), for example, the side wall portion 120 is extended from the main body portion 110 and forms an included angle (for example, an included angle of 90 degrees) with a plane where the main body portion 110 is located, and the side wall portion 120 may include two first side walls oppositely disposed along a length direction of the main body portion 110, two second side walls oppositely disposed along a width direction of the main body portion, and the like.

For ease of understanding, the following is a brief explanation of the principle by which the protective case 100 according to the example of the present application can achieve the above-described advantageous effects:

as mentioned above, the dirt resistance and aging resistance of the current plastic protective cases (e.g., mobile phone protective cases) used in electronic devices are still to be improved. Specifically, in the current protective shell, a thermoplastic elastomer (for example, a thermoplastic polyurethane elastomer, TPU) is generally used to make a side wall portion of the protective shell, or the entire protective shell is made of the thermoplastic elastomer, which is relatively soft, so that the hand feeling of holding and pressing a button of a user can be improved, and the scratch is not easily caused. However, the inventors found that the thermoplastic elastomer has poor dirt resistance and yellowing resistance, and the protective shell made of the thermoplastic elastomer is easily dyed by the hand sweat of a user soaking into the protective shell or easily fading clothes such as jeans, so that the protective shell has poor appearance and poor usability. Particularly, a protective shell with a light color (such as a light pink color, a light blue color, and the like) changes more obviously after being dyed, and the appearance and the texture of the protective shell are seriously affected. In the protective case 100 of the present application, by providing the anti-fouling coating 140 on the outer side (i.e., the side away from the electronic device accommodating space 130) of the side wall portion 120 formed of the thermoplastic elastomer, the anti-fouling coating 140 can better protect the side wall portion 120, dirt and the like is not easily adhered to the outer surface of the protective case 100, and the dirt is easily wiped off; moreover, the anti-smudge coating 140 can block ultraviolet rays, prevent the side wall portion 120 formed by the thermoplastic elastomer from aging and yellowing due to ultraviolet rays absorption, and the anti-smudge coating 140 can block hand sweat and the like from entering the protective shell 100 through micropores in the thermoplastic elastomer, and reduce the degree of yellowing of the protective shell 100 due to oxidation of the hand sweat, so that the protective shell 100 has good service performance and long service life.

According to some examples of the present application, the material forming the body portion 110 is not particularly limited, for example, the body portion 110 may be formed of polycarbonate, and the body portion 110 formed of polycarbonate has high hardness and strength, and may better support and protect an electronic device (e.g., a mobile phone).

According to other examples of the present application, the material forming the main body portion 110 may also be the same as the material forming the side wall portion 120, that is, the main body portion 110 may also be formed of a thermoplastic elastomer, and more specifically, the main body portion 110 and the side wall portion 120 may be integrally molded, for example, by a one-time injection molding process using a thermoplastic elastomer. Also, referring to fig. 3, when the main body portion 110 is formed of a thermoplastic elastomer, the anti-smudge coating 140 may be further provided on a surface of the first face 11 of the main body portion 110 on a side away from the second face 12. Thus, the anti-stain coating 140 can further protect the main body 110 formed of the thermoplastic elastomer, improve the stain resistance and yellowing resistance of the entire protective case 100, and improve the usability of the protective case 100.

According to further examples of the present application, referring to fig. 4, the body part 110 may include a first body part 111 and a second body part 112 which are arranged in a stack, wherein the second body part 112 is arranged near the electronic device accommodating space 130, and the anti-fouling coating 140 is further arranged on a surface of the first body part 111 on a side away from the second body part 112. Specifically, the material forming the first body portion 111 may include a thermoplastic elastomer, and the material forming the second body portion 112 may include polycarbonate; more specifically, the first body portion 111 and the sidewall portion 120 may be integrally formed, that is, the first body portion 112 may be formed by injection molding of polycarbonate, the first body portion 111 and the sidewall portion 120 may be formed on the outer side of the second body portion 112 by injection molding of thermoplastic elastomer, and the anti-fouling coating 140 may be formed on the outer side of the first body portion 111 and the sidewall portion 120 by spraying. Therefore, the second main body part 112 has better strength and hardness, and can better protect and support the electronic equipment; the first body portion 111 is located outside the second body portion 112, so that the protective shell 100 is not prone to scratching, and usability of the protective shell 100 is improved; moreover, the appearance of the protective case 100 is uniform, that is, the first body 111 and the sidewall 120 are integrally formed of the same material on the outer side of the protective case 100, and there is no boundary line between different materials, which further improves the appearance of the protective case 100; moreover, the anti-smudge coating 140 can further protect the protective shell 100, improve the anti-smudge performance and the anti-yellowing performance of the protective shell 100 as a whole, and improve the usability of the protective shell 100.

Specifically, referring to fig. 4, the thickness h of the first body 111 may be 0.5-0.7mm, for example, 0.55mm, 0.6mm, or 0.65mm, and thus when the thickness of the first body 111 is within the above range, the protective shell 100 may be prevented from being scratched, the hand feeling of the user may be improved, the light and thin design of the protective shell 100 may be facilitated, and the appearance effect of the protective shell 100 may be further improved. Specifically, the thickness L of the second main body 112 may be 0.6 to 0.9mm, for example, 0.65mm, 0.7mm, 0.75mm, 0.8mm, and the like, so that the second main body 112 having the thickness has better strength and hardness, and can better protect the electronic device, and when the thickness of the second main body 112 is within the above range, the injection molding is facilitated, the injection molding deformation and the like are not easy to occur, and the appearance effect and the usability of the protective case 100 are further improved.

According to some examples of the present application, referring to fig. 2 and 4, the thickness d of the anti-smudge coating 140 may be 2-15 μm, for example, may be 4 μm, may be 5 μm, may be 6 μm, may be 8 μm, may be 10 μm, may be 12 μm, may be 14 μm, and the like. When the thickness of the anti-stain coating layer 140 is within the above range, the sidewall portion 120 and the main body portion 110 formed of the thermoplastic elastomer can be well protected, and the anti-stain capability and the anti-yellowing capability of the protective case 100 can be improved. When the thickness of the anti-smudge coating 140 is too small, for example, less than 2 μm, the protective case 100 may not be well protected; when the thickness of the anti-smudge coating 140 is too large, for example, greater than 15 μm, raw materials are wasted, and the original color effect of the main body portion 110 and the sidewall portion 120 is affected, which affects the appearance of the protective shell 110.

Specifically, the anti-fouling coating 140 is transparent, and the material forming the anti-fouling coating 140 may include ultraviolet light curing paint (UV paint) or polyurethane paint (PU paint) or the like. Therefore, the anti-stain coating 140 formed of the above material has high transparency and good oil repellency, and dirt and the like are not easily adhered and are easily wiped off, and the anti-stain coating 140 formed of the above material can better block ultraviolet rays and the like, thereby improving the anti-yellowing capability of the protective case 100 and further improving the service life and the use performance of the protective case 100. Specifically, the material forming the anti-smudge coating 140 may include propylene glycol methyl ether, ethyl acetate, butyl acetate, etc., and propylene glycol methyl ether may be used as a solvent to sufficiently dissolve other paint raw materials without causing damage to the sidewall 120 formed of the thermoplastic elastomer.

According to some examples of the present application, referring to fig. 5, the protective case 100 may further include an appearance layer 150, the appearance layer 150 may be disposed on a side of the first face 11 of the body part 110 away from the second face 12, and the appearance layer 150 may include at least one of a color layer, a pattern layer, and a veneer layer. Therefore, the appearance layer 150 can further enrich the appearance effect of the protective shell 100, improve the texture of the protective shell 100, and improve the user experience. Specifically, when the main body 110 is made of polycarbonate, a leather-like, laser engraved LOGO, or printed pattern marks may be attached to the first surface 11 of the main body 110 on the side away from the second surface 12; specifically, when the main body 110 is formed of a thermoplastic elastomer, the appearance layer 150 may be formed on the first surface 11 of the main body 110 away from the second surface 12, and then the anti-stain coating 140 may be formed on the appearance layer 150 away from the main body 110 by spraying.

According to some examples of the present application, to further understand the protective shell 100 of the present application, a method of preparing the protective shell 100 of the present application is briefly described below, in particular, with reference to fig. 2 and 6, the method comprising:

s100: forming the main body part by a first injection molding process

In this step, the main body is formed by a first injection molding process. According to some examples of the present application, a first material (e.g., polycarbonate) may be subjected to a first injection molding process using a first mold to form a body portion. Specifically, the injection temperature of the first injection molding treatment may be 270-310 ℃, for example, 270 ℃, 280 ℃, 290 ℃, 300 ℃ or the like; specifically, the temperature of the first mold may be 80 to 100 ℃, for example, 85 ℃, 90 ℃, 95 ℃ or the like. Accordingly, when the injection temperature of the first injection process and the temperature of the first mold are within the above ranges, the injection molding of polycarbonate is facilitated, and the body portion having excellent strength and hardness can be formed. Specifically, the injection pressure, injection speed, pressure holding time, and the like of the first injection process may be adjusted according to the shape of the manufactured body, the mold gate method, and the like.

Specifically, before forming the main body part by the first injection molding process, the method may further include: the injection molded pellets, such as polycarbonate injection molded pellets, used for injection molding the body portion are subjected to a drying process to remove moisture absorbed during transportation and storage thereof, further improving the properties of the second body portion produced. Specifically, the polycarbonate injection molding particles can be baked for 3-5h at 95-100 ℃.

S200: forming the side wall part by a second injection molding process

In this step, the side wall portion is formed on the periphery of the main body portion manufactured in the preceding step by the second injection molding process. According to some examples of the present application, a second injection molding process may be performed on a second material (e.g., a thermoplastic elastomer) using a second mold to form the sidewall portion. Specifically, the injection temperature of the second injection molding treatment may be 210-230 ℃, for example, 215 ℃, 220 ℃, 225 ℃ or the like; specifically, the temperature of the second mold may be 30 to 50 ℃, for example, 35 ℃, 40 ℃, 55 ℃ or the like. Therefore, when the injection temperature of the second injection molding process and the temperature of the second mold are in the above ranges, the injection molding of the thermoplastic elastomer is facilitated, and the sidewall portion having good flexibility can be formed. Specifically, the injection pressure, injection speed, dwell time, and the like of the second injection molding process may be adjusted according to the shape of the sidewall portion to be produced, the mold gate method, and the like.

Specifically, before forming the side wall portion by the second injection molding process, the method may further include: the injection molded pellets are dried to remove moisture absorbed during transportation and storage, further improving the properties of the sidewall part produced. Specifically, the thermoplastic elastomer injection molding particles can be baked for 3-5h at 85-95 ℃.

S300: performing a punching process to form a first opening and a second opening

In this step, the main body portion and the side wall portion formed in the previous step are subjected to punching processing to form a first hole penetrating the main body portion and a second hole penetrating the side wall portion. Specifically, numerical control machining (CNC) can be adopted to punch a hole so as to form a first hole and a second hole, the first hole can include a camera hole, a flash lamp hole and the like, and the second hole can include a data line hole, an earphone line hole, an elevating camera hole and the like.

S400: formation of anti-smudge coating

In this step, the anti-stain coating is formed on the outer surface of the side wall portion formed in the preceding step. Specifically, the main body part and the side wall part formed in the previous step can be clamped on a jig, and after clamping is completed, only the side wall part needing spraying is exposed, so that the main body part is shielded; then cleaning the outer surface of the side wall part by using a plasma cleaning machine; and then spraying UV paint or PU paint on the outer surface of the side wall part, and curing, wherein the sprayed UV paint can be cured for 5min at 80 ℃, the PU paint can be baked for 5min in an oven at 80 ℃, or the natural curing can be completed after the storage for 7 days in a warehouse, and the like. Specifically, the thickness of the anti-fouling coating formed after spray curing can be 2-15 μm.

S500: forming an appearance layer

According to some examples of the present application, after the anti-smudge coating is formed in the previous step, an appearance layer may be formed on the outer surface of the body portion, for example, a LOGO may be embossed; color layers can be formed by silk-screen printing of color ink and the like, for example, different colors of ink can be silk-screen printed to form a protective shell with a gradient color or color collision effect; imitation leather can also be stuck. From this, the outward appearance effect and the performance of the protective housing of preparing have further been improved.

To sum up, protective housing in this application has good resistant dirty and anti-yellowing performance, and this protective housing performance is good, and appearance effect preferred.
