Description

Technical Field

[0001] This specification relates to the field of mobile phone case technology, and in particular to a partitioned light guide mobile phone case. Background Technology

[0002] As an essential accessory for everyday mobile phone use, phone cases not only serve the primary function of protecting the phone but also decorate its appearance, allowing users to express their personality. Among the dazzling array of phone cases available, LED illuminated phone cases have emerged. These cases contain light-emitting elements that can emit different brightness and colors of light based on user selection or external conditions (such as sound). Some LED illuminated phone cases even feature LED dot matrix displays to show information (such as time, call reminders, etc.).

[0003] However, the display effect of existing LED illuminated phone cases is not satisfactory. First, non-dot matrix LED illuminated phone cases often use a large backlight as the light source for the entire phone case, resulting in a very simple display effect; while dot matrix LED illuminated phone cases have very small light-emitting points, resulting in a small display area that is difficult to see.

[0012] In the partitioned light guide phone case of the embodiments of this specification, the diffusion component further includes a protective layer disposed on the inner surface of the base layer.

[0013] In the partitioned light guide mobile phone case of the embodiments of this specification, a reflector is provided on the outer surface of the mobile phone case body, and multiple LED point light sources of the point-to-surface conversion device are arranged at equal intervals and in a regular manner on the outer surface of the reflector.

[0044] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification. For example, in the following description, forming a second component on top of a first component can include embodiments where the first component and the second component are formed in direct contact, and can also include embodiments where the first component and the second component are formed in a non-direct contact manner (i.e., additional components may be included between the first component and the second component), etc.

[0045] Furthermore, for ease of description, some embodiments of this specification may use spatially relative terms such as "above," "below," "top," and "under" to describe the relationship between one element or component and another (or more) elements or components as shown in the accompanying drawings of the embodiments. It should be understood that, in addition to the orientations described in the drawings, the spatially relative terms are also intended to include different orientations of the device during use or operation. For example, if the device in the drawings is flipped, an element or component described as "below" or "under" other elements or components will subsequently be positioned "above" or "on top" other elements or components.

[0046] Figure 1 This specification illustrates a partitioned light-guiding mobile phone case according to some embodiments, which includes a mobile phone case body 10. The mobile phone case body 10 is provided with a plurality of point-to-surface conversion devices 20. Each point-to-surface conversion device 20 is used to convert the built-in point light source into a surface light source for display. In this way, it can realize independent display of multiple areas (such as independent light emission display of multiple pattern areas) and greatly expand the light emission area of ​​the light source, thereby effectively improving the display effect of the mobile phone case.

[0047] like Figure 2 As shown in some embodiments of this specification, the light-emitting area formed by the dot-to-surface conversion device 20 can be of any size, shape, and arrangement to achieve a specific display effect (e.g., multiple dot-to-surface conversion devices collaboratively displaying a pattern of a group of randomly arranged koi fish). The specific design can be customized according to actual needs. The thickness of the dot-to-surface conversion device 20 can be several millimeters (e.g., 1.0mm to 2mm) to facilitate easy integration into a mobile phone case.

[0048] Combination Figure 3 As shown in some embodiments of this specification, each of the point-to-surface conversion devices may include: a reflector 201, a light guide 202, a diffuser 203, and an LED point light source 204; the reflector 201, the light guide 202, and the diffuser 203 are stacked from the inside out.

[0049] Combination Figure 3 As shown, in some embodiments of this specification, the LED point light source 204 of each point-to-surface conversion device is used to generate point emission light as a built-in point light source; the LED point light source 204 of each point-to-surface conversion device can be integrated onto the corresponding reflector 201. The LED point light source 204 can be selected from white lamps, other color monochromatic lamps, or RGB tri-color lamps, etc.

[0050] In addition, when the required light-emitting area is large, multiple LED point light sources 204 can be used to guide light into the light guide component 202 from different angles to enhance brightness and light uniformity.

[0051] Combination Figure 3 As shown, in some embodiments of this specification, the reflective component 201 of each of the point-to-surface conversion devices is used to reflect the point-emitted light to the light guide component 202 to enhance the light intensity of the point-emitted light input to the light guide component 202. In some embodiments of this specification, the reflective component 201 may be made of a lightweight and highly reflective material, such as polycarbonate (PC), polyethylene terephthalate (PET), etc.

[0052] Combination Figure 3 As shown, in some embodiments of this specification, the light guide component 202 of each point-to-surface conversion device is used to propagate the point emitted light internally by total internal reflection and conduct it to the diffusion component 203 in the form of diffuse reflected light.

[0053] Combination Figure 4 As shown in some embodiments of this specification, each light guide component includes a total reflection layer 2021 and a diffuse reflection layer 2022 disposed on the inner surface of the total reflection layer. The total reflection layer 2021 is used to propagate the point-emitted light through total internal reflection (to reduce light loss during propagation), that is, the point-emitted light is propagated through reciprocating total internal reflection within itself, thereby diffusing to the entire total reflection layer 2021; in order to achieve propagation of the point-emitted light through total internal reflection, it can enter the total reflection layer 2021 at a certain angle. The diffuse reflection layer 2022 is used to convert the total internal reflection light at the corresponding position into diffuse reflection light and transmit it outward. The diffuse reflection layer 2022 can be a densely distributed reflective protrusion on the inner or outer surface of the total reflection layer 2021; each reflective protrusion can be used to disrupt the total internal reflection of the total reflection layer 2021 at that position, increasing the emission angle of the diffuse reflection light, thereby enabling it to exit from the front of the total reflection layer 2021. In addition, considering the loss of light propagation, the size of the reflection point can be reduced at positions closer to the corresponding LED point light source, and increased at positions farther from the light source. That is, the size of the reflection convex point is positively correlated with its distance relative to the corresponding LED point light source, so as to improve the uniformity of light emission.

[0054] Combination Figure 4As shown, in some embodiments of this specification, the total reflection layer 2021 and the diffuse reflection layer 2022 can be integrally formed, that is, the reflective bumps densely distributed on the inner or outer surface of the total reflection layer 2021 can be integrally formed on the total reflection layer 2021. In other embodiments of this specification, the reflective bumps can also be formed on the inner or outer surface of the total reflection layer 2021 by screen printing or other processes. In some embodiments of this specification, the reflective bumps can be arranged in a regular, evenly spaced layout (e.g., a matrix layout); in other embodiments of this specification, the reflective bumps can also be arranged irregularly (e.g., varying the spacing and / or size of the reflective bumps). In some embodiments of this specification, both the total reflection layer 2021 and the diffuse reflection layer 2022 can be made of materials with good optical conductivity, high strength, impact resistance, and light weight (e.g., acrylic).

[0055] Combination Figure 3 As shown in some embodiments of this specification, the diffusion component 203 of each point-to-surface conversion device is used to diffuse the diffused light into a surface light source and transmit it outward, thereby completing the conversion of the point light source into a surface light source for display.

[0056] Combination Figure 5 As shown, in some embodiments of this specification, each diffusion component 203 may include a substrate layer 2031 and a refractive layer 2032 disposed on the outer surface of the substrate layer 2031; the substrate layer 2031 is used to transmit and conduct the diffused light; the refractive layer 2032 is used to randomly refract the diffused light into a surface light source and transmit it outward. The refractive layer 2032 may be microspheres of different sizes and mixed distribution densely distributed on the outer surface of the substrate layer 2031. These microspheres of varying sizes can cause random refraction of light, thereby achieving the effect of diffusing light. In other embodiments of this specification, the diffusion component may also include a protective layer 2033 disposed on the inner surface of the substrate layer 2031. In some embodiments of this specification, the substrate layer 2031 may be made of a thin and lightweight material (e.g., PET plastic material) with good mechanical properties (e.g., high mechanical strength and high flexibility) and good optical conductivity. The refractive layer 2032 may be made of a thin and lightweight material with good optical conductivity (e.g., acrylic). In some embodiments of this specification, the diffusion component 203 may have a certain degree of fogging to make the displayed image more delicate and realistic.

[0057] refer to Figure 6As shown in some embodiments of this specification, a reflector 301 is provided on the outer surface of the phone case body 10 of the partitioned light-guiding phone case. Multiple LED point light sources 204 of point-to-surface conversion devices are arranged at equal intervals on the outer surface of the reflector 301. The reflector sub-area around each LED point light source 204 forms a reflective component corresponding to the point-to-surface conversion device; that is, the reflective components of multiple point-to-surface conversion devices are integrally formed on one reflector 301. In some embodiments of this specification, the reflector 301 can be a reflective printed circuit board (PCBA), i.e., other highly reflective materials are applied to the PCBA board to provide reflective functionality. The LED point light sources 204 are mounted on the front (i.e., outer surface) of the reflective PCBA board, and other components are mounted on the back, making the front relatively flat and facilitating the installation of other components. The reflective PCBA board preferably uses high-brightness white solder resist to achieve a better reflective effect. The LED point light sources 204 integrated on the reflective PCBA board are side-emitting, facilitating the emission of light from the side of the light-guiding component 202.

[0058] Continue to refer to Figure 6 As shown in some embodiments of this specification, the phone case body 10 further includes a light guide plate frame 302 covering the reflector 301. The light guide plate frame 302 has multiple regularly arranged, equally spaced hollow areas. Each hollow area is used to accommodate one light guide component 202 and one LED point light source 204. Each light guide component 202 is slightly smaller than its corresponding hollow area to facilitate placement within the hollow area and fixation to the light guide plate frame 302. An arc-shaped groove is formed in the middle of the upper edge of each hollow area, which easily accommodates the LED point light source 204.

[0059] Continue to refer to Figure 6 As shown, in some embodiments of this specification, the light guide plate frame 302 is made of a highly reflective material. This avoids light leakage at the edges of the light guide assembly 202 during operation, preventing crosstalk between closely spaced point-to-surface conversion devices and affecting performance. It also avoids the problem of reduced efficiency and brightness of the point-to-surface conversion devices caused by light leakage. Therefore, the light guide plate frame 302 both supports multiple point-to-surface conversion devices and achieves light isolation between them. Furthermore, the thickness of the light guide assembly 202 and the light guide plate frame 302 is basically the same to ensure that after being embedded in the light guide plate frame 302, a flat surface is formed, avoiding unevenness on the surface of the partitioned light guide phone case. Otherwise, it would affect aesthetics, reduce structural strength, and be detrimental to phone protection. In some embodiments of this specification, the material of the light guide plate frame 302 can be a highly reflective, high-strength, and tough reflective material, such as PC or PVC. The color of the light guide plate frame 302 is preferably white or silver to increase the reflective effect.

[0060] Continue to refer to Figure 6 As shown in some embodiments of this specification, the phone case body 10 also includes a diffuser plate 303 covering the light guide plate frame 302. Each diffuser component 203 forms a diffuser component of a corresponding point-to-surface conversion device, that is, multiple reflective components of point-to-surface conversion devices are integrally formed on a diffuser plate 303.

[0061] Continue to refer to Figure 6 As shown, in some embodiments of this specification, the phone case body 10 further includes a decorative cover plate 304 covering the diffuser plate 303. (In conjunction with...) Figure 7 As shown, the decorative cover 304 can be provided with multiple display windows (such as...). Figure 7 The polygonal frame in the display case allows for the application of one or more user-defined patterns (such as heart shapes, koi fish, facial masks, smiley faces, and other emoticons) on each display window. When multiple patterns are used, they can correspond to the positions of multiple point-to-surface conversion devices to achieve the visual effect of independently illuminating different patterns in multiple areas. Furthermore, since the decorative cover 304 is located on the outermost layer, it also provides protection.

[0062] Continue to refer to Figure 6 As shown in some embodiments of this specification, a first groove 101 is formed on the outer surface of the phone case body 10, and a second groove 102 is formed at the bottom of the first groove 101. The reflector 301, the light guide plate frame 302, and the light guide component 202 are fitted into the second groove 102 (i.e., the shapes of the reflector 301, the light guide plate frame 302, and the light guide component 202 are adapted to the shape of the second groove 102, and their dimensions are slightly smaller than the second groove 102). The outer surfaces of the light guide plate frame 302 and the light guide component 202 are basically flush with the bottom of the first groove 101. The diffuser 303 and the decorative cover 304 are fitted into the first groove 101 (i.e., the shapes of the diffuser 303 and the decorative cover 304 are adapted to the shape of the first groove 101, and their dimensions are slightly smaller than the first groove 101). The outer surface of the decorative cover 304 is basically flush with the outer surface of the phone case body 10. In some embodiments of this specification, the decorative cover 304 is made of a thin and light material with good light-guiding properties.

[0063] refer to Figure 1 As shown in some embodiments of this specification, the sides of the phone case body 10 are preferably made of a flexible material, such as thermoplastic polyurethane (TPU), to facilitate fitting onto the phone; while other parts of the phone case body 10 are preferably made of a relatively hard material, such as PC / acrylic, to provide better structural strength.

[0064] It should also be understood that, in the embodiments of this specification, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0065] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an apparatus or device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an apparatus or device. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the apparatus or device that includes said element.

[0066] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
