Detailed Description
In one aspect of the present application, a protective case for an electronic device is provided. As can be understood, with reference to fig. 1a and 1b, the protective case 10 includes: a body 100, wherein the body 100 has a hollow portion 110, and the hollow portion 110 has a light source opening region 111 therein; and a light guide film 200, wherein the light guide film 200 is disposed at one side of the body 100 and surrounds the hollow portion 110, and the light guide film 200 is used for emitting the light 55 emitted from the light source into the light guide film 200 at a predetermined region of the body 100. The inventor finds that, in the protective case 10, the light guide film 200 is disposed on one side of the main body 100, so that the light guide film 200 can guide out the light 55 emitted by the light source, and the protective case 10 can emit the light 55 when the electronic device obtains the predetermined information, thereby playing a role of prompting the predetermined information, and can directly utilize the existing light emitting component on the electronic device to emit light, and other structures and components are not required, so that the protective case has a simple structure, is low in cost, and is easy to industrialize.
Further, it is understood that the material forming the body 100 is not particularly limited, specifically, the material forming the body 100 may be an organic material, specifically, polycarbonate, and the form thereof is not particularly limited, for example, injection molding grade plastic particles of polycarbonate, etc., and those skilled in the art may flexibly select the material according to actual needs, and will not be described in detail herein.
Further, it can be understood that the specification, size, and the like of the body 100 are not particularly limited, and since the body serves as a protective shell of an electronic device, the specification and size of the body 100 can be selected according to the specification and size of the electronic device used, and a person skilled in the art can select the size and specification of the body 100 according to actual needs, which is not described in detail herein.
Further, it is understood that the shape of the hollow-out portion 110 is not particularly limited, and the hollow-out portion 110 is located on the protective shell 10, and functions as: when the protective case 10 is applied to an electronic device, the hollow portion 110 is used to expose the structures and components of the electronic device that need to be exposed. For example, in the related art, the electronic device has a photographing component, such as a camera, and the like, at this time, the hollow portion 110 is located on the protective shell 10, and when the protective shell 10 is used on the electronic device, the camera can be exposed through the hollow portion, so that normal photographing and photographing functions are realized. Therefore, the shape of the hollow portion 110 may be larger than the structure or the component, as long as the shape can completely expose the structure or the component that needs to be exposed on the electronic device to realize the normal function of the electronic device.
Further, it is understood that the shape of the light source opening area 111 is not particularly limited, the light source opening area 111 is located inside the hollow portion 110, and is not a solid structure or component located on the hollow portion 110, and it refers to only a specific area inside the hollow portion 110, and when the protective case 10 is used on an electronic device, the location of the light source opening area 111 is the location of the light emitting component on the electronic device. For example, in some examples of the present application, a flash lamp is provided on an electronic device, and when the protective case 10 is used on the electronic device, the position of the light source opening region 111 of fig. 1a is exactly the position of the flash lamp. Of course, the light source opening area 111 in fig. 1a is originally a defined area that is manually divided, and therefore, the shape and size thereof may vary according to the shape and size of the light emitting component of the electronic device, when the light emitting component of the electronic device on which the protective case 10 is used is a circle, the light source opening area 111 is a circle, when the light emitting component of the electronic device on which the protective case 10 is used is a square with a side length of 1cm, the light source opening area 111 is a square with a side length of 1mm, that is, the shape and size of the light source opening area 111 are not limited by the shape and size in fig. 1a, and when the light emitting component of the electronic device on which the protective case 10 is used is a square, the light source opening area 111 of which shape and which size should be defined.
Further, it is understood that the material forming the light guide film 200 is not particularly limited, and those skilled in the art can flexibly select the material according to actual needs as long as the requirements are satisfied. For example, in some examples of the present application, a material forming the light guiding film 200 may be an organic material, specifically, may be polycarbonate, and a form thereof is not particularly limited, for example, the material may be injection molding grade plastic particles of polycarbonate, and a person skilled in the art may flexibly select the material according to actual needs, and redundant description is omitted herein; in other examples of the present application, the light guiding film 200 may be made of a translucent material with a certain color, so that the light emitted from the light source of the light guiding film 200 can be made into a color with a more obvious prompting effect, such as yellow. Therefore, when the protective shell 10 is used for electronic equipment, the prompting function can be better played.
Further, it is understood that the light guide film 200 may be silk-screened with a customized pattern, for example, in some examples of the present application, the light guide film 200 may be silk-screened with a lettering pattern, thereby making the protective case 10 more commercially promising.
Further, it is understood that the predetermined area is located so as to better enable the user to perceive the emitted light, thereby better prompting the predetermined information. For example, in some examples of the present application, with reference to fig. 1b, the light 55 exits in a direction substantially perpendicular to the body 100. The emission direction of the light 55 and the main body 100 are not necessarily absolutely perpendicular to each other, but the emission direction of the light 55 may be inclined relative to each other within a certain angle range, and for example, when the emission direction of the light 55 is inclined within 5 degrees from the direction perpendicular to the main body 100, the light emission direction may be understood as "substantially perpendicular" here. Therefore, in the using process of the protective shell 10, the emitting direction of the light 55 can be directly emitted towards the user, so that the user can more easily sense the light emitted from the protective shell 10, and the predetermined information acquired by the electronic device can be better prompted.
Further, one possible specific structure of the light guiding film 200 described above is described in detail below according to an example of the present application:
it is understood that in some examples of the present application, in conjunction with FIG. 2, the light directing film 200 may further include: a base film 210; and a plurality of light guide structures 220 arranged at intervals, wherein the light guide structures 220 are arranged on the surface of the base film 210 close to the body 100. Therefore, light is guided by the light guide structure 220, and when light emitted from the light source is incident into the light guide structure 220, the light guide structure guides the light to a predetermined region of the body 100 for emission. Therefore, by arranging the light guide structure 220, the effect of guiding light to the predetermined area of the body 100 for emission is better, and light is further emitted when the electronic device acquires predetermined information, so that the prompt effect on the predetermined information is achieved.
It is understood that the base film 210 and the light guide structure 220 may be formed separately or integrally. In some examples of the present application, the base film 210 and the light guide structure 220 are integrally formed. Therefore, the base film 210 and the light guide structure 220 that are integrally formed do not have an obvious interface between the base film 210 and the light guide structure 220, and thus the reflection and refraction of light rays in the light guide structure 220 are not influenced too much; in addition, the base film 210 and the light guide structure 220 are integrally formed, so that the manufacturing process is simpler and more convenient, and industrialization is easy to realize.
Further, in the process of using the protective shell 10 in practice, a mobile phone is taken as an example (it can be understood by those skilled in the art that the description is only given by taking a mobile phone as an example, but not limiting the present application, the protective shell claimed in the present application can be used not only for a mobile phone, but also for other types of electronic devices, and will not be repeated in the following description), especially at night, many users are used to place the back of a mobile phone downward and the front of the mobile phone upward (i.e. the display screen upward and the flash lamp downward). At this time, after the mobile phone receives a new message and the screen of the mobile phone becomes a black screen, the new message acquired by the mobile phone cannot be prompted to the user. Therefore, the whole rear shell of the mobile phone needs to be luminous, and unread new information can be identified through the flash of the edge of the protective shell. And the more light guide structures, the more light is guided outThe higher the flux is, the brighter the light is, and further, in order to ensure that the whole surface of the mobile phone case emits light uniformly, the distance between two adjacent light guide structures 220 is gradually reduced in the direction away from the light source opening area 111. For example, referring to fig. 3, in fig. 3, a distance d between two adjacent light guide structures 2203Is less than d2Is less than d1. Therefore, the closer to the light source opening area 111, the smaller the number of the light guide structures, and the farther from the light source opening area 111, the denser the distribution of the light guide structures, so that the whole surface of the protective shell 10 can uniformly emit light, and when the electronic device is back-buckled, the light guide structure can also play a role in prompting predetermined information.
Further, it is understood that the shape of the light guide structure 220 is not particularly limited, for example, in some examples of the present application, the light guide structure 220 may be cylindrical, truncated cone, cubic, or hemispherical, etc. As long as the light guide structure 220 can normally realize the light guide function, that is, the specific shape can be flexibly selected by those skilled in the art according to actual needs, and will not be described in detail herein. After a great deal of research and examination, the inventor finds that when the light guide structure 220 is cylindrical, the light guide effect is better; meanwhile, the preparation is simple and convenient, and the industrial production is easy to realize.
Further, the height of the light guide structure 220 may be 0.05mm to 0.15 mm. In particular, in some examples of the present application, the height of the light guiding structure may specifically be 0.05mm, or 0.05mm, etc. From this, this light-directing structure 220's height is comparatively suitable, both can realize the effect of leaded light better, also can not lead to the thickness of whole protective housing too thick too much too thick, does not conform to the development trend of frivolousization.
Further, the thickness of the base film may be 0.15mm to 0.45mm, specifically, 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, or 0.45 mm; accordingly, the thickness of the body 100 may be 0.7mm to 1.0mm, and specifically, may be 0.7mm, 0.8mm, 0.9mm, 1.0mm, or the like. Therefore, the height of the above structure is appropriate, which can be matched with the light guide structure 220 to better realize the light guide effect, and the over-thickness of the whole protective shell can not be caused by the over-thickness, so that the protective shell is not in line with the development trend of light and thin.
Further, on the surface of the light guide structure 220 close to the body 100, a distance between two points farthest apart in any direction is 0.1mm to 0.4mm, and specifically, the distance may be 0.1mm, 0.2mm, 0.3mm, 0.4mm, or the like. The distance between the two points farthest away in any direction is different when the light guide structures 220 have different shapes, for example, in some examples of the present application, the light guide structures 220 have a cylindrical shape, and the surface of the light guide structures 220 close to the body 100 means that the cylindrical shape is close to the bottom surface of the body 100; the distance between two points farthest apart in any direction means the diameter of the bottom surface of the cylinder; for another example, in other examples of the present application, the light guide structure 220 is a regular hexahedron, and the surface of the light guide structure 220 close to the body 100 refers to a surface of the regular hexahedron close to the body 100; the distance between two points farthest apart in any direction refers to the side length of the regular hexahedron. Therefore, the distance can enable the plurality of light guide structures 220 to be arranged well, so that more space is occupied to lead out more light; meanwhile, the light guide structure 220 with the above characteristics is relatively simple to manufacture and easy to realize industrialization.
Further, it can be understood that the distance between two adjacent light guide structures 220 is not greater than 8 mm. Specifically, in some examples of the present application, a distance between two adjacent light guide structures 220 may be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, or the like. Therefore, the light guide structure 220 can guide out the light with sufficient flux, so that the protective shell 10 can stably realize the prompting function of the predetermined information.
Further, in a specific example of the present application, in conjunction with fig. 4, there are at least two concentric annular regions (for example, a first annular region 221 and a second annular region 222 in fig. 4) around the light source opening region 111, the shape of the outer periphery of the annular regions is similar to the shape of the outer periphery of the light source opening region (it should be noted that, here, the similarity refers to the same shape and different size of the patterns), the density of the distribution of the plurality of light guide structures in each of the annular regions is substantially the same (for example, in fig. 4, the density of the distribution of the light guide structures in each of the first annular regions 221 is substantially the same, the density of the distribution of the light guide structures in each of the second annular regions 222 is substantially the same), and the density of the distribution of the plurality of light guide structures is gradually increased in a direction gradually away from the center of the annular regions (for example, in fig. 4, the density of the distribution of light guiding structures in the second annular region 222 is significantly greater than the density of the distribution of light guiding structures in the first annular region 221). Further, in an inside-out direction, a distance between two adjacent light guide structures in the annular region gradually decreases. It should be noted that, in the foregoing, only two annular regions surrounding the light source opening region 111 are taken as an example for illustration, but those skilled in the art can understand that more annular regions may also surround the light source opening region 111, and redundant description is not repeated herein; in addition, it should be noted that, the light guide structure is not provided in each portion of the annular region, for example, since the annular region is disposed around the light source opening region 111, there is a high possibility that the annular region has an overlapping portion with the hollow-out portion 110, and those skilled in the art can understand that the light guide structure is not provided in the portion where the annular region overlaps with the hollow-out portion 110. Therefore, the distribution mode of the light guide structures is the same as the shape of the light source opening area 111, and the distribution density of the light guide structures is dense in each part far away from the light source opening area 111; each part closer to the light source opening area 111, the intensity of the light guide structure distribution is sparse, and is lower than the intensity of the light guide structure distribution on the part farther from the light source opening area 111 in the communication direction, that is, the intensity of the whole light guide structure takes the light source opening area 111 as the central point to present a divergence shape, and the closer to the light source opening area 111, the more sparse the light guide structure distribution is, so that the whole protective shell 10 is more uniform in light emission, and the better prompt function is played for the predetermined information.
Further, it can be understood that, in other examples of the present application, in combination with fig. 5, the protective casing is divided into a plurality of predetermined regions, for example, a first predetermined region 223, a second predetermined region 224, a third predetermined region 225, and a fourth predetermined region 226 in fig. 5, and as the distance between the predetermined region and the light source opening region 111 increases, the distance between two adjacent light guide structures in the predetermined region gradually decreases. Therefore, the distribution mode of the light guide structures is the same as the shape of the light source opening area 111, and the distribution density of the light guide structures is dense in each part far away from the light source opening area 111; in each part close to the light source opening area 111, the distribution density of the light guide structures is sparse and lower than the distribution density of the light guide structures in the part far from the light source opening area 111 in the communication direction, that is, the density of the whole light guide structure takes the light source opening area 111 as a central point to be in a divergent shape, and the light guide structures are distributed more sparsely closer to the light source opening area 111, so that the whole protective shell 10 can emit light more uniformly, and the preset information can be better prompted; in addition, the manufacturing process is simple and convenient, and industrialization is easy to realize.
Further, it can be understood that the inside of the light guide structure may further contain a matte powder. For example, in some examples of the present application, based on the total mass of the light guide film, the mass percentage of the matte powder is not greater than 3%, specifically, the mass percentage may be 1%, 2%, or 3%, and the like, and the matte powder may be acrylic powder, so that the light guide effect of the light guide structure is better and brighter, and the whole protective shell 10 may exhibit an appearance effect of a frosted or matte surface, so that the protective shell has a texture more, and the grade of the protective shell is further improved.
Further, the materials forming the protective shell may be transparent materials. Therefore, on one hand, the protective shell can be ensured to emit light on the whole surface; on the other hand, because the transparent material is adopted, when the electronic device is applied to the electronic device, the color and the shape of the rear shell of the electronic device cannot be shielded.
Further, with reference to fig. 6, at least a portion of the edge of the protective casing 10 may further include a protective film 300, where the thickness of the protective film may be 1.1mm to 1.3mm, and specifically, the thickness of the protective film may be 1.1mm, 1.2mm, or 1.3mm, etc. Therefore, the thickness of the protective film 300 is not too thin to protect the product well, and is not too thick to make the whole product bulky.
Further, it can be understood that the material forming the protective film 300 may be a thermoplastic polyurethane elastomer, the specific form may be injection-molded transparent plastic particles of the thermoplastic polyurethane elastomer, the specific forming manner of the protective film 300 may be skin injection molding, and the forming may be directly performed in a skin injection mold, and the specific steps thereof, for example, the step of baking the protective film at 90 ℃ for 4 hours to remove moisture before injection molding, may be flexibly selected by those skilled in the art according to actual needs, and will not be described herein in too much detail. In addition, a predetermined amount of toner can be added according to the actual product requirement when the sheath is injected and fed, the injection temperature of the sheath injection can be 210-230 ℃, the mold temperature can be 30-50 ℃, and the injection pressure, injection speed, pressure holding time and the like can be specifically adjusted according to the product shape, the mold gate mode and the like, and redundant description is omitted.
In another aspect of the present application, a method of making a protective case for an electronic device is provided. It will be appreciated that in conjunction with fig. 7 and fig. 8a and 8b, the method includes the steps of:
s100: a prefabricated film 199 is formed on one side of the substrate 99 (see fig. 8a for a schematic structural view).
It is to be understood that the specific manner of forming the prefabricated film 199 is not particularly limited, and in some examples of the present application, the prefabricated film 199 may be formed in a manner of being coated with a hot melt adhesive and then directly attached to the surface of one side of the substrate 99; in other examples of the present application, the light guide film may be further formed by in-mold insert injection molding. Specifically, a metal injection mold is designed according to the designed product size, and the prefabricated film 199 is placed in the metal injection mold and injection-molded from the back side. In order to improve the reliability of the product, the periphery of the prefabricated film needs to be wrapped during injection molding. In addition, as will be understood by those skilled in the art, the raw material before injection molding is baked at a temperature of 95 ℃ to 100 ℃ for 4 hours to remove moisture.
