DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] [First embodiment]

[0027] like Figure 1-Figure 2 As shown, an embodiment of the utility model provides a protective case 1. The protective case 1 can be used to be mounted on an electronic device and protect the electronic device, especially an electronic device with a light-emitting portion, such as a mobile phone, a tablet computer, etc. The protective case 1 includes, for example: a back panel 10 and a side frame 20. A functional area 11 is provided on the back panel 10. The side frame 20 is arranged around the edge of the back panel 10. The functional area 11 includes a light-guiding portion 111, and the position of the light-guiding portion 111 corresponds to the position of the light-emitting portion on the electronic device, and the light-guiding portion 111 is used to guide the light emitted by the light-emitting portion of the electronic device to the outside of the back panel 10.

[0028] The back plate 10 is, for example, the bottom plate of the protective case 1, and a functional area 11 is provided at a position relative to the functional parts of the electronic device. The functional parts of the electronic device include, for example, a camera, a light emitting unit, etc., and the light emitting unit includes, for example, light emitting elements such as a flash, a fill light, and a lighting lamp. The purpose of providing the functional area 11 on the back plate 10 is to protect the functional parts of the electronic device to prevent the functional parts from being damaged when the electronic device falls, and to expose the camera, flash, etc. to prevent them from being blocked and unable to function.

[0029] The side frame 20 is arranged around the edge of the back plate 10, and together with the back plate 10, forms a storage space for placing electronic devices. The electronic device can be placed in the storage space, so that the protective case 1 can still be located in the storage space when the electronic device falls, thereby achieving the purpose of protecting the electronic device. The inner side of the back plate 10 is the side facing the storage space, and the outer side of the back plate 10 is the side away from the storage space.

[0030] The functional area 11 includes a light guide portion 111, which is arranged at a position relative to the light emitting portion of the electronic device. When the surrounding environment is dark, brighter photos can be taken using the light emitted by the light emitting portion of the electronic device.

[0031] The light guide 111 is a light-transmitting component that can absorb the light irradiated on one surface and transmit it to the other surface to emit the light. The position of the light guide 111 corresponds to the light-emitting portion so as to guide the light emitted by the light-emitting portion to the outside of the back plate, thereby preventing part of the light from being unable to be absorbed by the light guide 111, thereby reducing the amount of light passing through the light guide 111. Since one surface of the light guide 111 faces the light-emitting portion of the electronic device and the other surface faces the outside of the back plate 10, the light emitted by the light-emitting portion of the electronic device located on the inside of the back plate 10 can be guided from the inside of the back plate 10 to the outside of the back plate 10.

[0032] In this embodiment, a light guiding portion 111 is provided on the functional area 11 of the protective shell 1, and the light generated by the light emitting portion of the electronic device is guided to the outside through the light guiding portion 111, so that the light emitted by the light emitting portion of the electronic device will not be affected by the thickness of the protective shell 1, and after being guided to the outside, the amount of light will not be reduced due to the action of the light guiding portion 111. Therefore, compared with the prior art, the amount of light generated by the light emitting portion of the electronic device can be increased, thereby not affecting the shooting effect of the electronic device, thereby improving the user's sense of use and experience.

[0033] In a preferred embodiment of the utility model, the light-guiding portion 111 includes a light-transmitting structure made of a light-guiding material, and the light emitted by the light-emitting portion of the electronic device is guided to the outside of the back panel 10 via the light-transmitting structure. The light-guiding material includes, for example, glass or polymer materials. For example, polymer materials include polymethyl methacrylate, polystyrene, polycarbonate, styrene acrylonitrile copolymer, polymethyl isoprene, transparent polyamide, etc. The light-guiding material has good light-transmitting properties, so that the light-transmitting structure made of the light-guiding material can efficiently absorb the light emitted by the light-emitting portion of the electronic device, and will not reduce the amount of light in the process of transmitting the light, so that the amount of light emitted by the light-emitting portion will not be reduced after being transmitted to the outside of the back panel. At the same time, the light-guiding material has good plasticity and can be formed into different shapes and structures. The specific shape of the light-transmitting structure can also be set according to actual needs, which is not limited here.

[0034] In one embodiment of the present invention, Figure 1-Figure 2 As shown, the functional area 11 further includes, for example, a light guide installation hole 112, and the light guide 111 is connected to a hole wall 1121 of the light guide installation hole 112. Figure 2 As shown, the light guide mounting hole 112 is a through hole opened at the position of the functional area 11 relative to the light emitting part of the electronic device. The shape of the light guide mounting hole 112 is, for example, consistent with the shape of the light emitting part, which can prevent the functional area 11 from blocking the light emitted by the light emitting part without affecting the protective performance of the protective shell 1. For example, when the light emitting part is circular, the light guide mounting hole 112 is also circular; when the light emitting part is non-circular, the light guide mounting hole 112 is also non-circular. The light guide 111 is an independently formed component, which is connected to the hole wall 1121 of the light guide mounting hole 112. The shape of the light guide portion 111 is, for example, consistent with the shape of the light guide portion mounting hole 112, so that when the light guide portion 111 is connected to the hole wall 1121 of the light guide portion mounting hole 112, it can fill the entire light guide portion mounting hole 112, and there is no gap between the hole wall 1121 and the light guide portion 111. On the one hand, it can avoid the problem of light emitted by the light-emitting portion leaking from the gap between the light guide portion 111 and the hole wall 1121, resulting in a reduction in the amount of light. On the other hand, the hole wall 1121 can be connected to the light guide portion 111 in all directions, so that the light guide portion 111 will not fall off easily when the protective shell 1 falls accidentally.

[0035] In a preferred embodiment of the present invention, Figure 2-Figure 4 As shown, a first clamping portion 1111 is provided on the side wall of the light guide portion 111, and a second clamping portion 1122 corresponding to the first clamping portion 1111 is provided on the hole wall 1121, and the first clamping portion 1111 is clamped with the second clamping portion 1122. Specifically, as Figure 4 and Figure 5As shown, the side wall of the light guide 111 is a side surface arranged between the surface of the light guide 111 facing the light emitting part of the electronic device and the surface away from the light emitting part of the electronic device. The first clamping portion 1111 arranged on the side wall of the light guide 111 is, for example, a structure protruding from the side wall toward the hole wall 1121 of the light guide mounting hole 112. In this embodiment, the light guide is an annular structure, and the first clamping portion 1111 can be, for example, an outward annular protrusion. Correspondingly, a second clamping portion 1122 is arranged on the hole wall 1121 of the light guide mounting hole 112. The second clamping portion 1122 is, for example, a circle of annular groove structures arranged around the hole wall 1121, and the annular groove structure corresponds to the annular protrusion structure. The annular protrusion structure of the first clamping portion 1111 is clamped into the annular groove structure of the second clamping portion 1122, so that the light guide 111 is clamped on the light guide mounting hole 112. In other embodiments, the first clamping portion 1111 is, for example, an annular groove structure arranged around the side wall of the light guide portion 111, and the second clamping portion 1122 is, for example, an annular protrusion structure arranged around the hole wall 1121. The specific structures of the first clamping portion 1111 and the second clamping portion 1122 can be arranged according to actual conditions, and are not specifically limited here. The light guide portion 111 and the hole wall 1121 are clamped together by the first clamping portion 1111 and the second clamping portion 1122, so that the light guide portion 111 can be easily assembled and disassembled. On the one hand, the production efficiency of the protective shell 1 can be improved, and on the other hand, when the light guide portion 111 is accidentally damaged, a new light guide portion 111 can be easily replaced, which has the characteristics of simple structure, convenience and speed.

[0036] Furthermore, if Figure 5 As shown, the light guide portion 111 further includes an opaque coating 1112. The opaque coating 1112 is disposed on the side wall of the light guide portion 111, and the opaque coating 1112 includes, for example, a vinyl coating, a PVC coating, and a PTFE coating, etc., which can prevent light leakage from the side wall of the light guide portion 111, and prevent external light from propagating through the side wall of the light guide portion to the camera, thereby causing certain effects when the camera is used for taking photos or videos, such as glare when the camera is taking photos, etc., thereby causing a negative impact on the camera's photographic effect and affecting the camera's video effect.

[0037] Furthermore, if Figure 5As shown, the surface of the light guide portion 111 is a plane. In the present embodiment, the surface of the light guide portion 111 is the top surface and the bottom surface of the light guide portion 111. The top surface of the light guide portion 111 may be the end surface of the light guide portion 111 away from the accommodating space, and the bottom surface of the light guide portion 111 is the end surface of the light guide portion arranged in the accommodating space. The bottom surface may be in contact with the light emitting portion on the electronic device, or may not be in contact with the light emitting portion. When the surface of the light guide portion 111 is a plane, when the light emitted by the light emitting portion of the electronic device is transmitted to the outside of the back plate 10 through the light guide portion 111, due to the effect of the plane mirror, the direction of the light generated by the light emitting portion does not change, and can be directly projected to the outside of the back plate. Therefore, the surface of the light guide portion 111 is a plane, which can ensure that the shooting effect after the light guide portion 111 is set is the same as the shooting effect before the light guide portion 111 is set.

[0038] In a preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, the functional area 11 also includes a camera avoidance hole 114, and the camera avoidance hole 114 is spaced apart from the light guide portion 111. The camera avoidance hole 114 is a hole that is opened at a position of the functional area 11 relative to the camera of the electronic device and does not affect the function of the camera of the electronic device. The camera avoidance hole 114 is spaced apart from the light guide portion 111, so that on the one hand, the protective shell 1 between the camera avoidance hole 114 and the light guide portion 111 can protect the light-emitting portion and the camera of the electronic device separately, and on the other hand, the light-emitting portion and the camera of the electronic device can be protected by the protective shell around the light guide portion mounting hole 112 and the camera avoidance hole 114, respectively, thereby improving the protection performance of the protective shell 1 on the electronic device without affecting the functions of the camera and the light-emitting portion.

[0039] Furthermore, the functional area 11 also includes, for example, a protective portion 113, and the protective portion 113 is disposed between the light guide portion 111 and the camera avoidance hole 114, and the light guide portion 111 and the protective portion 113 are an integrally formed structure. The protective portion 113 is, for example, a protective plate disposed on the functional area 11, and the light guide portion 111 and the protective portion 113 can be directly injection molded on a mold so that the light guide portion 111 and the protective portion 113 are injection molded into an integrally formed structure. The light guide portion 111 and the protective portion 113 are integrally formed, which improves the overall aesthetics of the protective shell 1, and ensures that when the protective shell 1 accidentally falls, the light guide portion 111 will not easily fall off from the protective portion 113, and has better strength and stability. In addition, since the light guide portion 111 and the protective portion 113 only need to complete the integral molding process in the same mold, there is no need to separately make a molding mold for the light guide portion 111, which reduces the steps of assembling and connecting the light guide portion 111 and improves production efficiency.

[0040] [Second embodiment]

[0041] The structure of the protective shell 1 provided in this embodiment is substantially the same as that of the protective shell 1 provided in the first embodiment, and the main difference therebetween is that the surface of the light guide portion 111 of the protective shell 1 in this embodiment is convex outward.

[0042] Specifically, Figure 6 As shown, in this embodiment, the surface of the light guide portion 111 is the top surface and the bottom surface of the light guide portion 111. The top surface of the light guide portion 111 can be the end surface of the light guide portion 111 away from the accommodating space, and the bottom surface of the light guide portion 111 is the end surface of the light guide portion arranged in the accommodating space. The bottom surface can be in contact with the light-emitting portion on the electronic device, or it can be not in contact. When the surface of the light guide portion 111 is convex outward, it has a convex lens effect, that is, it converges the light. After passing through the light guide portion 111, the light emitted by the light-emitting portion of the electronic device will converge due to the convex lens effect, which not only allows the light emitted by the light-emitting portion to be concentrated into a smaller area, but also can improve the brightness of the light. When the light-emitting portion of the electronic device needs to be used as a lighting device, if the brightness of the light-emitting portion is not enough, the light guide portion 111 can concentrate the light emitted by the light-emitting portion into a smaller area, thereby increasing the brightness of the area to improve the lighting effect of the light-emitting portion. When using an electronic device for macro photography, the light guide portion 111 allows the light to be concentrated on the part of the subject where details need to be highlighted, thereby improving the quality of macro photography. The light from the light emitting part is concentrated by the light guide part 111, so that the light from the light emitting part can be prevented from directly shining on the camera and causing glare. In a dark environment, the light guide part 111 increases the brightness of the light emitting part so that the camera can take brighter photos, thereby improving the camera's shooting effect and enhancing the user's sense of use and experience.

[0043] [Third embodiment]

[0044] The structure of the protective shell 1 provided in this embodiment is basically the same as the structure of the protective shell 1 provided in the first and second embodiments, and the main difference is that the surface of the light guiding portion 111 of the protective shell 1 in this embodiment is recessed toward the center of the light guiding portion 111 .

[0045] Specifically, Figure 7As shown, in this embodiment, the surface of the light guide portion 111 is the top surface and the bottom surface of the light guide portion 111. The top surface of the light guide portion 111 may be the end surface of the light guide portion 111 away from the accommodating space, and the bottom surface of the light guide portion 111 is the end surface of the light guide portion arranged in the accommodating space. The bottom surface may or may not be in contact with the light emitting portion on the electronic device. When the surface of the light guide portion 111 is concave toward the center of the light guide portion 111, it has a concave lens effect, that is, it diverges the light. The light emitted by the light emitting portion of the electronic device will diverge due to the concave lens effect after passing through the light guide portion 111, which can not only make the light emitted by the light emitting portion softer, but also expand the lighting range of the light emitting portion, so that the light emitting portion can illuminate a wide area. When the brightness of the light-emitting part is too high, it is easy to cause glare to the camera. At this time, the concave lens effect of the light-guiding part 111 can soften the light of the light-emitting part, which can not only avoid glare during shooting, but also help reduce shadows and highlight areas, so that the light can cover the subject more evenly and obtain a softer shooting effect, thereby improving the camera's shooting effect and enhancing the user's sense of use and experience.

Under the premise that the technical features do not conflict, the structures do not contradict, and the purpose of the present invention is not violated, the technical solutions of the various embodiments can be arbitrarily combined and used in combination.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
