DETAILED DESCRIPTION

[0009] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0010] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0011] The electronic device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0012] Please refer to Figure 1 to Figure 13 An embodiment of the present application discloses an electronic device, and the disclosed electronic device includes a mounting base 100, a reflective cover 300 and a light source assembly 200.

[0013] The mounting base 100 provides a mounting space for the components of the electronic device. The mounting base 100 is provided with a light-transmitting area 101 and a reflective surface 102, wherein the reflective surface 102 is located on one side of the light-transmitting area 101, and the light-transmitting area 101 and the reflective surface 102 are arranged opposite to each other. At this time, the light emitted by the light source of the electronic device is reflected by the reflective surface 102 and then emitted from the light-transmitting area 101. Specifically, the light-transmitting area 101 may have a light-entering side and a light-emitting side, wherein the light-entering side refers to the side where the light enters the light-transmitting area 101, and the light-emitting side refers to the side where the light exits the light-transmitting area 101. Since the light exits the light-transmitting area 101 through the reflective surface 102, the reflective surface 102 is located on the light-entering side of the light-transmitting area 101. In one embodiment, the mounting base 100 is formed with an inner cavity, and the light-transmitting area 101 is a partial side wall forming the inner cavity, and the reflective surface 102 is located in the inner cavity.

[0014] The reflector 300 and the reflective surface 102 are located on the same side of the light-transmitting area 101. The reflective surface 102 is arranged around the reflector 300, and the reflector 300 includes a reflective portion 310 and an annular diffusion portion 320. The annular diffusion portion 320 here can diffuse the light, so that the light is more uniform and dispersed. The reflective portion 310 can reflect the light. The annular diffusion portion 320 is connected to the reflective portion 310, and the annular diffusion portion 320 extends along the circumference of the reflective portion 310. It can also be understood here that the annular diffusion portion 320 is arranged along the outer peripheral edge of the reflective portion 310. Or the annular diffusion portion 320 can also be a partial side of the reflector 300.

[0015] The light source assembly 200 includes a plurality of light-emitting components 220, where the light-emitting components 220 are the light sources mentioned above. The light-emitting components 220 may be LED lamps or other elements capable of emitting light, and the specific type of the light-emitting components 220 is not limited herein. The plurality of light-emitting components 220 are located on the side of the reflector 300 away from the light-transmitting area 101. The plurality of light-emitting components 220 are arranged in the inner ring area of ​​the annular diffuser 320 and are arranged at intervals along the circumference of the annular diffuser 320. The light emitted by the plurality of light-emitting components 220 passes through the reflector 300 and the reflecting surface 102 and then is emitted from the light-transmitting area 101.

[0016] In a specific operation process, the light emitted by the light emitting element 220 will be reflected by the reflective portion 310 of the reflective cover 300 , and then pass through the annular diffusion portion 320 to be emitted toward the reflective surface 102 , and then be emitted from the light-transmitting area 101 after being reflected by the reflective surface 102 .

[0017] In the embodiment disclosed in the present application, the reflective portion 310 can reflect the light emitted by the light emitting element 220, and the reflected light is further diffused by the annular diffuser 320 and then emitted to the light-transmitting area 101 through the reflective surface 102. Therefore, the embodiment disclosed in the present application can improve the optical uniformity by reflecting and diffusing the light, thereby avoiding the phenomenon of the light ring having a hot spot, thereby improving the uniformity of the light emitted by the electronic device, and thus improving the appearance performance of the electronic device.

[0018] In addition, compared with the solutions in the related art, the present application can reflect the light multiple times through the reflective portion 310 of the reflector 300, thereby improving the utilization rate of light energy. Therefore, the technical solution disclosed in the present application has a better utilization rate of light energy. In addition, the annular diffuser 320 can not only diffuse the light, but also shield the visibility of the device. The annular diffuser 320 has a good shielding effect, thereby further avoiding the risk of exposing the internal devices of the electronic device, thereby further improving the appearance performance of the electronic device.

[0019] In addition, the present application utilizes the reflective portion 310 and the annular diffuser 320 to improve the light guiding uniformity and also expand the light transmission range, thereby reducing the number of light emitting elements 220 and reducing the manufacturing cost of the electronic device.

[0020] Optionally, the reflective portion 310 can be made of materials such as PC (polycarbonate), glass, etc. The reflectivity of the reflective portion 310 can be greater than 97.5%, and its transmittance can be less than 0.1%. The type of reflection generated by the reflective portion 310 can be specular reflection, or of course diffuse reflection. In an optional solution, the reflective portion 310 can be made of white PC material, and the refractive index of the reflective portion 310 can be 1.58.

[0021] In an optional embodiment, the annular diffusion part 320 may include a light-transmitting body and a diffusion film, and the diffusion film is attached to the light-transmitting body. Alternatively, in another optional solution, the main body material of the annular diffusion part 320 may be silicone, and a diffusing agent is added to the silicone, so the annular diffusion part 320 may be made of a composite material of silicone and a diffusing agent. The annular diffusion part 320 in the present application may have a higher refractive index. For example, the refractive index of the annular diffusion part 320 may be 1.67. Of course, the refractive index of the annular diffusion part 320 may also be other values, which are not limited herein.

[0022] In another optional embodiment, the electronic device may further include an annular reflector 400, which is disposed on the side of the reflector 300 away from the light-transmitting area 101. In this case, the annular reflector 400 and the reflector 300 may be located on the same side of the light-transmitting area 101, and at the same time, the annular reflector 400 is located on the side of the reflector 300 away from the light-transmitting area 101, that is, the light-transmitting area 101, the reflector 300 and the annular reflector 400 are arranged in sequence. The annular reflector 400 may be arranged opposite to the reflecting portion 310, and the inner edge of the annular reflector 400 is provided with a plurality of first notches 401 arranged at intervals along the circumference thereof, and the outer edge of the annular reflector 400 is provided with a plurality of second notches 402 arranged at intervals along the circumference thereof. The plurality of first notches 401 and the plurality of second notches 402 are arranged one by one, and each light-emitting element 220 is arranged opposite to a first notch 401.

[0023] Specifically, the reflecting portion 310 and the annular reflecting member 400 can form a reflecting gap, and the light-emitting surface of the light-emitting member 220 faces the reflecting portion 310. At this time, the light emitted by the light-emitting member 220 is first emitted to the reflecting portion 310, and then reflected by the reflecting portion 310 and emitted to the annular reflecting member 400 on the opposite side of the reflecting portion 310, and after multiple reflections by the reflecting portion 310 and the annular reflecting member 400, it is emitted from the annular diffusion portion 320 to the reflecting surface 102, and then emitted from the reflecting surface 102 to the light-transmitting area 101.

[0024] In this scheme, the annular reflector 400 can further improve the utilization rate of light, and the reflector 310 and the annular reflector 400 form a double reflection structure, which is more conducive to improving the uniformity of light emitted by the electronic device. In addition, the annular reflector 400 has notches on the inner ring edge and the outer ring edge corresponding to the light emitting element 220, thereby weakening the intensity of the reflected light in the area corresponding to the light emitting element 220. The intensity of the reflected light in the area directly facing the light emitting element 220 of the reflector 310 is greater than the intensity of the reflected light in the area of ​​the reflector 310 away from the light emitting element 220 along the circumferential direction. Therefore, by providing notches on the inner ring edge and the outer ring edge corresponding to the light emitting element 220 on the annular reflector 400, the reflected light in the area directly facing the light emitting element 220 of the annular reflector 400 can be weakened, so that the intensity of the reflected light in the circumferential direction of the reflection gap formed by the reflector 310 and the annular reflector 400 is more consistent, which is more conducive to uniform light emission, thereby further improving the light emission uniformity of the electronic device.

[0025] Optionally, the reflector may be silver-plated PC or glass. Of course, the reflector may also be made of other materials, which is not limited herein. In one solution, the reflectivity of the reflector is greater than 97%.

[0026] In the above embodiment, part of the annular reflector 400 may be located below the annular diffuser 320, that is, the surface of the annular diffuser 320 on the side away from the reflector 300 may be directly overlapped on the annular reflector 400. Alternatively, the annular reflector 400 may be located at the inner edge of the annular diffuser 320, that is, the outer diameter of the annular reflector 400 is less than or equal to the inner diameter of the annular diffuser 320.

[0027] In the above embodiment, the reflective surface 102 is an annular surface, so the light effect formed by the electronic device is an annular light effect. In order to optimize the layout space of the electronic device, the reflective portion 310 of the reflective cover 300 can be set to an annular structure, and the camera module of the electronic device is opposite to the inner ring area of ​​the reflective portion 310. At this time, the external light enters the camera module after passing through the light-transmitting area 101 and the inner ring area of ​​the reflective portion 310, thereby realizing the shooting operation of the camera module. However, since the reflective portion 310 has a high reflection performance, the light reflected by the reflective portion 310 is likely to interfere with the camera module, thereby affecting the shooting performance of the camera module.

[0028] In another optional embodiment, the reflector 300 further includes a light shielding portion 330, the reflective portion 310 is arranged around the light shielding portion 330, and the light shielding portion 330 may be provided with a light through hole 331, and the light through hole 331 is arranged opposite to the light-transmitting area 101. The light shielding portion 330 here is used to isolate light, that is, the light shielding portion 330 cannot transmit light. The light through hole 331 here is used to expose the lens of the camera module, so that the external light passes through the light-transmitting area 101 and then shoots toward the light through hole 331, and then enters the lens of the camera module through the light through hole 331.

[0029] In this solution, the shading portion 330 can play a role in isolating light, thereby avoiding the influence of the reflecting portion 310 on the camera module. In addition, the shading portion 330 is also a supporting body of the reflecting portion 310, thereby improving the overall strength and rigidity of the reflector 300. In addition, the shading portion 330 can also be used to support the camera module, thereby simplifying the connection structure of the electronic device.

[0030] Optionally, the light shielding portion 330 may be made of black PC material. Alternatively, the base material of the light shielding portion 330 may be a transparent resin, and then ink is screen-printed on the transparent resin to form the light shielding portion 330. The light transmittance of the light shielding portion 330 is less than 0.1%.

[0031] In one solution, the reflective portion 310, the annular diffuser 320 and the shading portion 330 can be assembled and connected by bonding, clamping or the like. Alternatively, in another optional solution, the reflective portion 310, the annular diffuser 320 and the shading portion 330 are three-color injection molded. In other words, the reflector 300 is integrally injection molded. The three-color injection molding here is similar to the two-color injection molding, except that the two-color injection molding is a molding process in which two different materials are injected into the same set of molds, thereby realizing that the molded parts are formed of two materials. The three-color injection molding is a molding process in which three different materials are injected into the same set of molds, thereby realizing that the molded parts are formed of three materials.

[0032] In order to further improve the light uniformity of the electronic device, in another optional solution, the reflective portion 310 includes a first ring body 311 and an outer baffle 312, and the outer baffle 312 extends from the outer edge of the first ring body 311 in a direction away from the light-transmitting area 101, that is, the outer baffle 312 here is located on the side of the first ring body 311 away from the light-transmitting area 101. The annular diffuser 320 is arranged on the surface of the side of the outer baffle 312 away from the light-transmitting area 101, and the annular diffuser 320 extends along the circumference of the outer baffle 312. At this time, the annular diffuser 320 is located below the outer baffle 312, and the below here is relative to the position of the first ring body 311, that is, the first ring body 311 is located above the outer baffle 312, and the annular diffuser 320 is located below the first ring body 311. At this time, the outer baffle 312 and the annular diffuser 320 together form the side of the reflector 300.

[0033] The outer retaining wall 312 may include a plurality of protrusions 3121, which are arranged at intervals along the circumference of the first ring body 311, and the height of each protrusion 3121 decreases from the middle position to the two side positions. At this time, the direction in which the protrusion 3121 decreases from the middle position to one of the side positions is along the circumference of the first ring body 311. Therefore, the height of the protrusion 3121 changes along the circumference of the first ring body 311.

[0034] The height direction of the raised portion 3121 here can be understood as the axial direction of the reflector 300, or as the thickness direction of the reflector 300. Of course, it can also be understood that the raised portion 3121 has a first end face and a second end face that are arranged opposite to each other, and the first end face is connected to the first ring body 311. Therefore, the first end face can be understood as a reference plane, and the height of the raised portion 3121 can be the distance between the first end face and the second end face. Therefore, the distance between the first end face and the second end face decreases along the middle position of the raised portion 3121 to the positions on both sides.

[0035] Each light emitting member 220 is disposed corresponding to a protrusion 3121 , and each light emitting member 220 may be opposite to a middle position of the protrusion 3121 .

[0036] In this solution, since the light emitting element 220 is opposite to the middle position of the protrusion 3121, it can be understood that each light emitting element 220 is arranged at the highest position of the outer baffle 312 of the reflective portion 310, so the highest position of the outer baffle 312 can block more light from the light emitting element 220, thereby reducing the light output of the area directly facing the reflector 300 and the light emitting element 220. The farther the reflector 300 is from the light emitting element 220, the lower the height of the corresponding outer baffle 312 is, so the amount of light blocked from the light emitting element 220 is greater, thereby increasing the light output, so that the light output of the circumferential light of the reflector 300 is consistent or relatively close, thereby further improving the light output uniformity of the electronic device.

[0037] In the above solution, by utilizing the height change of the outer baffle wall 312, the light output amount can be adjusted, which is more conducive to the uniformity of light output of the electronic device.

[0038] In an optional solution, the highest position of the raised portion 3121 is located below the light-emitting surface of the light-emitting element 220, and the distance between the light-emitting surface and the highest position of the raised portion 3121 can be 0.2 mm. The lowest position of the raised portion 3121 can be located above the light-emitting element 220, and the distance between the light-emitting surface and the lowest position of the raised portion 3121 can be 0.6 mm. At this time, the distance between the highest position and the lowest position of the raised portion 3121 is controlled at 0.8 mm. Of course, the distance between the highest position and the lowest position of the raised portion 3121 and the light-emitting surface of the light-emitting element 220 can also be other values, which are not limited in this article.

[0039] In another optional solution, the entire raised portion 3121 is located above the light-emitting surface. In this case, the distance between the light-emitting surface and the highest position of the raised portion 3121 can be 0.2 mm. And the distance between the light-emitting surface and the lowest position of the raised portion 3121 can be 0.6 mm. In this case, the distance between the highest position and the lowest position of the raised portion 3121 is controlled at 0.4 mm. Of course, the distance between the highest position and the lowest position of the raised portion 3121 and the light-emitting surface of the light-emitting element 220 can also be other values, which are not limited herein.

[0040] In the above embodiment, the light-emitting surface of the light-emitting element 220 can be lower than the lower edge of the reflective surface 102, so as to avoid the light-emitting element 220 directly irradiating the light-emitting surface, and further avoid the phenomenon of the light ring having a burst point. Specifically, the light-emitting surface of the light-emitting element 220 can be 1 mm lower than the lower edge of the reflective surface 102. Of course, other values ​​can also be used, which are not limited in this article.

[0041] In another optional solution, the annular diffuser 320 has a first surface 321 and a second surface 322 that are arranged opposite to each other, the second surface 322 faces the outer baffle wall 312, and the first surface 321 faces away from the outer baffle wall 312. The second surface 322 may include a plurality of arc-shaped concave surfaces 3221 arranged at intervals along the extension direction of the annular diffuser 320, and each arc-shaped concave surface 3221 is in contact with the surface of the protrusion 3121. At this time, the outer baffle wall 312 and the annular diffuser 320 form the side wall of the reflector 300. In this solution, the shape of the second surface 322 of the annular diffuser 320 matches the shape of the surface of the outer baffle wall 312, thereby improving the matching performance of the annular diffuser 320 and the outer baffle wall 312, making the overall structure of the reflector 300 more regular and compact.

[0042] In an optional solution, the second surface 322 is composed of a plurality of arc-shaped concave surfaces 3221 connected end to end, thereby forming a wavy annular surface matching the outer retaining wall 312. The first surface 321 may be an annular plane.

[0043] In another optional embodiment, a first groove 3111 is provided between two adjacent protrusions 3121. The second surface 322 may have a plurality of first protrusions 3222, and a first protrusion 3222 is provided between two adjacent arc-shaped concave surfaces 3221. At least a portion of each first protrusion 3222 may be embedded in its corresponding first groove 3111. In this solution, the first protrusion 3222 is embedded in the protrusion 3121, and the first protrusion 3222 here is actually an undercut, and the corresponding undercut can pull the protrusion 3121, thereby improving the injection molding strength of the annular diffuser 320 and the reflector 310, and further improving the connection reliability of the annular diffuser 320 and the reflector 310.

[0044] Furthermore, each arc-shaped concave surface 3221 may be provided with a second protrusion 323 along a side facing the outer retaining wall 312, and the outer side wall of the protrusion 3121 is provided with a second groove 3122, and at least part of the second protrusion 323 is embedded in the second groove 3122. This solution can further improve the connection reliability between the annular diffuser 320 and the reflector 310.

[0045] In an optional solution, the second groove 3122 is located in the middle position of the protrusion 3121. At this time, the first grooves 3111 are arranged on both sides of the protrusion 3121, and the second groove 3122 is arranged in the middle position of the protrusion 3121. Therefore, the middle and two side positions of each protrusion 3121 are connected to the annular diffuser 320 through undercuts, which is more conducive to improving the connection reliability between the annular diffuser 320 and the reflection part 310.

[0046] In another optional solution, the reflective portion 310 may further include an inner baffle 313, the inner baffle 313 may be disposed at the inner edge of the reflective portion 310, and the outer baffle 312 may be disposed around the inner baffle 313. The inner baffle 313, the outer baffle 312, and the first ring body 311 may enclose an annular groove 3101, and the light emitting member 220 is disposed opposite to the annular groove 3101. In this case, the plurality of light emitting members 220 may be arranged at intervals along the extension direction of the annular groove 3101.

[0047] In this solution, the inner retaining wall 313 can reflect the large-angle light from the light source, thereby helping to improve the utilization rate of the light.

[0048] Furthermore, a plurality of recessed portions 3131 arranged at intervals along the extension direction of the inner retaining wall 313 may be provided on one side of the inner retaining wall 313 facing the outer retaining wall 312, and each light emitting element 220 is arranged opposite to a recessed portion 3131. In this solution, the recessed portion 3131 can avoid the light emitting element 220, thereby facilitating the reduction of the occupied space of the reflector 300 and the light source assembly 200. In addition, the recessed portion 3131 can also reduce the intensity of the reflected light in the area directly facing the light emitting element 220, thereby making the intensity of the circumferential reflected light of the reflective portion 310 closer, thereby further improving the light uniformity of the electronic device.

[0049] In another optional solution, the light source assembly 200 may also include a circuit board 210, and the circuit board 210 may be located on a side of the reflector 300 away from the light transmission area 101. The annular diffuser 320 may be located between the reflector 310 and the circuit board 210. A plurality of light emitting elements 220 may be arranged on a side of the circuit board 210 facing the reflector 300. The annular reflector 400 may be attached to a side of the circuit board 210 facing the reflector 300. In this solution, the circuit board 210 can be used to carry the light emitting elements 220 and can be electrically connected to the light emitting elements 220, thereby simplifying the structure of the electronic device.
