[0037] Combine the following Figures 1 to 18 An electronic device 100 according to an embodiment of the present application is described.

[0038] like Figure 1 As shown, an embodiment of the present application provides an electronic device 100, including: a device body 110; a light-transmitting member 120, which is arranged on the device body 110; and an infrared component 130, which is arranged on the device body 110; wherein the light emitted by the infrared component 130 enters the light-transmitting member 120 and generates an evanescent wave on the side of the light-transmitting member 120 away from the infrared component 130.

[0039] In an embodiment of the present application, the electronic device 100 includes a device body 110, a light-transmitting member 120 and an infrared component 130. The light-transmitting member 120 and the infrared component 130 are both arranged on the device body 110. The light emitted by the infrared component 130 is irradiated onto the light-transmitting member 120 and is totally reflected on the side of the light-transmitting member 120 away from the infrared component 130, thereby generating an evanescent wave on the side of the light-transmitting member 120 away from the infrared component 130, and the evanescent wave is propagated along the side of the light-transmitting member 120 away from the infrared component 130, so that the evanescent wave can be emitted from one end of the electronic device 100, thereby realizing the infrared remote control function of the electronic device 100.

[0040] Furthermore, the electronic device 100 provided in the present application performs infrared remote control with the help of evanescent waves generated by total reflection of light, and there is no need to set an opening in the electronic device 100 for the infrared remote control function. Moreover, when the user performs infrared remote control operation, one end of the electronic device 100 is pointed at the controlled device, which is consistent with the user's action of using a remote control and makes it easier for the user to use the infrared remote control function of the electronic device 100.

[0041] like Fig.18 As shown, the electronic device 100 provided in the present application does not need to open a hole in the frame 112 to achieve the emission of infrared light from the end of the electronic device 100, thereby retaining the integrity of the appearance of the electronic device 100. In addition, compared with emitting infrared light through the camera position, the electronic device 100 provided in the present application is more in line with the user's daily usage habits, that is, by pointing the end of the electronic device 100 to the controlled device, the user's usage experience is improved.

[0042] The wavelength of the light emitted by the infrared component 130 is in the range of 760nm to 1300nm, and the light in this wavelength range is invisible to the human eye, that is, infrared light.

[0043] Optionally, the device body 110 includes a frame 112 , and the light-transmitting member 120 has one side of the frame 112 protruding from the frame 112 .

[0044] like Figure 1 and Figure 2 As shown, as a possible implementation, the refractive index of the light-transmitting member 120 is greater than the refractive index of air, and at least part of the light emitted by the infrared component 130 is irradiated in the light-transmitting member 120 to the side of the light-transmitting member 120 facing away from the infrared component 130 at an incident angle greater than or equal to the critical angle between the light-transmitting member 120 and the air.

[0045] Specifically, Figure 3 As shown in Figure 1, evanescent waves will be generated under total reflection, that is, when the incident light is incident from a denser medium to a less dense medium, if the incident angle is greater than or equal to the critical angle θc between the denser medium and the less dense medium, the reflected light will be totally reflected, and an evanescent wave of a certain intensity will appear on the side of the less dense medium, and the evanescent wave will propagate along the surface of the less dense medium. The incident angle is the angle between the incident light and the normal.

[0046] According to the above principle, the refractive index of the light-transmitting member 120 is greater than the refractive index of the air. Therefore, when light is incident from the light-transmitting member 120 to the air, if the incident angle is greater than or equal to the critical angle between the light-transmitting member 120 and the air, total reflection will occur and an evanescent wave of a certain intensity will be generated on the air side, that is, on the side of the light-transmitting member 120 away from the infrared component 130, and propagate along the surface of the light-transmitting member 120.

[0047] Among them, the critical angle θc=arcsin(n2 / n1), wherein n1 represents the refractive index of the optically denser medium, and n2 represents the refractive index of the optically sparser medium. In the present application, n1 represents the refractive index of the light-transmitting element 120, and n2 represents the refractive index of air.

[0048] The light that generates total reflection may be part of the light or all of the light emitted by the infrared component 130 .

[0049] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, as a possible implementation, the infrared component 130 includes: an infrared light source 132; a light guide 134, which is arranged between the infrared light source 132 and the light transparent member 120, and the light guide 134 is used to guide the light emitted by the infrared light source 132 to irradiate the side of the light transparent member 120 away from the light guide 134 at an incident angle greater than or equal to the critical angle between the light transparent member 120 and the air.

[0050] Specifically, the infrared component 130 includes an infrared light source 132 and a light guide 134. The light guide 134 is located between the infrared light source 132 and the light transparent member 120. The light guide 134 can adjust the propagation direction of the light emitted by the infrared light source 132 so that when a part of the light is incident on the air from the light transparent member 120, it is propagated in a manner where the incident angle is greater than or equal to the critical angle between the light transparent member 120 and the air, thereby ensuring the generation of total reflection and the reliability of the infrared remote control function.

[0051] Since the space inside the electronic device 100 is limited, the infrared light source 132 cannot be set at a larger angle. Therefore, by setting the light guide 134, the difficulty of layout inside the electronic device 100 can be reduced and the normal effect of the infrared remote control function can be ensured.

[0052] The light that generates total reflection may be part of the light or all of the light emitted by the infrared light source 132 .

[0053] That is, with the help of the light guide 134, the light emitted by the infrared light source 132 is incident on the light transparent member 120 at an angle greater than or equal to the critical angle θc, so that total reflection can occur at the junction of the light transparent member 120 and the air, causing the evanescent wave to propagate along the surface of the light transparent member 120 away from the infrared light source 132, and then can be emitted from the end of the electronic device 100 and control various controlled devices.

[0054] The light guide 134 is a columnar structure. Specifically, the shape of the light guide 134 includes but is not limited to a cylindrical shape, a rectangular shape, a triangular prism shape or other prism-shaped structures.

[0055] Furthermore, the light emitting direction of the infrared light source 132 can be perpendicular to the surface of the light transparent member 120 facing the infrared light source 132 , the light guide member 134 is in contact with the light emitting surface of the infrared light source 132 , and the light guide member 134 is also in contact with the surface of the light transparent member 120 facing the infrared light source 132 .

[0056] The function of the light guide 134 is to change the propagation path of the light through an internally designed optical structure so as to satisfy the requirement that the light is incident on the surface of the light-transmitting member 120 facing away from the infrared component 130 at an angle greater than or equal to the critical angle θc, and generates total reflection at the interface between the light-transmitting member 120 and the air, so that the evanescent wave propagates along the surface of the light-transmitting member 120 and is emitted from the end of the electronic device 100 for controlling various controlled devices.

[0057] The infrared light source 132 may be a chip that can emit infrared light.

[0058] As a possible implementation, the infrared component 130 further includes a circuit board 136 , and the infrared light source 132 is disposed on the circuit board 136 .

[0059] As a possible implementation, the refractive index of the light guide member 134 is greater than or equal to the refractive index of the light transparent member 120 .

[0060] Specifically, the refractive index of the light guide 134 is greater than or equal to the refractive index of the light transparent member 120 , thereby ensuring that the incident angle of light from the light transparent member 120 into the air is greater than or equal to the critical angle between the light transparent member 120 and the air.

[0061] Among them, when the refractive index of the light guide 134 is greater than the refractive index of the light transparent member 120, when the light enters the light transparent member 120 from the light guide 134, the refraction angle increases, thereby increasing the incident angle of the light from the light transparent member 120 to the air; when the refractive index of the light guide 134 is equal to the refractive index of the light transparent member 120, when the light enters the light transparent member 120 from the light guide 134, the refraction angle remains the same as the incident angle, thereby maintaining the incident angle of the light from the light transparent member 120 to the air.

[0062] The material of the light guide member 134 includes, but is not limited to, any material having a refractive index greater than or equal to the refractive index of the light-transmitting member 120 , such as glass, plastic, or resin.

[0063] Furthermore, the infrared light source 132 may be one, two or more lamp beads to ensure the light output efficiency of total reflection of the light.

[0064] As a possible implementation, Fig.10 and Fig.11 As shown, the light guide 134 is integrated on the infrared light source 132; or Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the light guide 134 and the infrared light source 132 are opposed to each other.

[0065] Specifically, Fig.10 and Fig.11 As shown, the light guide 134 can be integrated on the infrared light source 132 , that is, the light guide 134 constitutes a lampshade of the infrared light source 132 , thereby reducing the thickness of the infrared component 130 and reducing the thickness of the electronic device 100 .

[0066] That is, the light guide 134 is packaged on the infrared light source 132. This solution can cancel the packaging of the infrared light source 132, and only retain the light guide 134, which reduces the space occupied by the infrared component 130, is conducive to reducing the thickness of the electronic device 100, and can greatly save the stacking space inside the electronic device 100. In addition, it can be achieved that the infrared light can be emitted from the end of the electronic device 100 without opening a hole in the frame 112, which retains the integrity of the appearance of the electronic device 100 and conforms to the user's usage habits.

[0067] Among them, Figure 5 As shown, in order to ensure that the light guide member 134 and the light transmissive member 120 abut against each other, a heightening member 138 may be provided on the side of the infrared light source 132 facing away from the light transmissive member 120 .

[0068] Or, if Figure 1 , Figure 2 and Figure 4 As shown, the light guide 134 and the infrared light source 132 offset each other. By manufacturing the light guide 134 separately, the difficulty of producing the infrared light source 132 is reduced, and the production cost is reduced.

[0069] That is, the infrared light source 132 has its own packaging shell, and the light guide 134 is located on the light-emitting side of the infrared light source 132 .

[0070] The material of the packaging shell of the infrared light source 132 includes but is not limited to glass, plastic, resin, or any other material whose refractive index is greater than or equal to that of the light-transmitting element 120 . The materials of the light guide 134 and the packaging shell may be the same or different.

[0071] like Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, as a possible implementation, the light guide 134 is a hollow structure, and the inner wall 1342 of the light guide 134 has at least one protrusion 1344 .

[0072] Specifically, the light guide 134 is a hollow structure, and the inner wall 1342 of the light guide 134 has at least one protrusion 1344 , so that the light changes its propagation direction through reflection by the protrusion 1344 , so as to achieve the effect of total reflection on the side of the light-transmitting element 120 away from the infrared component 130 .

[0073] As a possible implementation, Figure 6 and Figure 7 As shown, the protrusion 1344 is an annular structure, and along the first direction, the inner wall 1342 of the light guide 134 has at least two protrusions 1344; or as shown Figure 8 and Fig. 9As shown, along the circumference of the light guide 134 , the inner wall 1342 of the light guide 134 has at least two protrusions 1344 , and along the first direction, the inner wall 1342 of the light guide 134 has at least two protrusions 1344 ; wherein the first direction is the direction from the infrared component 130 to the light-transmitting member 120 .

[0074] Specifically, Figure 6 and Figure 7 As shown, the protrusion 1344 is an annular structure, that is, the protrusion 1344 surrounds the inner wall 1342 of the entire light guide 134, and along the first direction, the inner wall 1342 of the light guide 134 has at least two protrusions 1344, that is, along the first direction, the interior of the light guide 134 has multiple layers of protrusions 1344, so that light can be reflected on at least two protrusions 1344, and then more light can be totally reflected on the surface of the light-transmitting member 120, thereby ensuring the energy of the evanescent wave and ensuring the normal use of the infrared remote control function.

[0075] Or, if Figure 8 and Fig. 9 As shown, along the circumference of the light guide 134, the inner wall 1342 of the light guide 134 has at least two protrusions 1344, that is, along the circumference of the light guide 134, the inside of the light guide 134 has at least two protrusions 1344, and along the first direction, the inner wall 1342 of the light guide 134 has at least two protrusions 1344, that is, along the first direction, the inside of the light guide 134 has multiple layers of protrusions 1344, so that light can be reflected on at least two protrusions 1344, and then more light can be totally reflected on the surface of the light transparent member 120, thereby ensuring the energy of the evanescent wave and ensuring the normal use of the infrared remote control function.

[0076] The first direction is the direction from the infrared component 130 to the light-transmitting element 120 .

[0077] That is, there are a plurality of protrusions 1344 on the inner wall 1342 of the light guide 134, which can change the path of the light emitted by the infrared light source 132, so that within the range of angles that the infrared light source 132 can emit, light at certain specific angles passes through the reflection path and is incident on the surface of the light-transmitting member 120 on the side away from the infrared light source 132 at an angle greater than or equal to the critical angle θc.

[0078] Furthermore, the surface of the protrusion 1344 may be a curved surface, a flat surface, or an inclined surface. Of course, the surface of the protrusion 1344 may also be a combination of at least two of the curved surface, the flat surface, and the inclined surface.

[0079] like Fig.10 , Fig.11 , Fig.12 and Fig.13As shown, as a possible implementation, the light guide 134 is a solid structure, and a side wall 1346 of the light guide 134 has at least one recess 1348 .

[0080] Specifically, the light guide 134 is a solid structure, and the side wall 1346 of the light guide 134 has at least one recess 1348 , so that the light changes its propagation direction through reflection by the recess 1348 , thereby achieving a total reflection effect on the side of the light-transmitting element 120 away from the infrared component 130 .

[0081] As a possible implementation, Fig.10 and Fig.11 As shown, the recess 1348 is an annular structure, and along the first direction, the side wall 1346 of the light guide 134 has at least two recesses 1348; or as shown in FIG. Fig.12 and Fig.13 As shown, along the circumference of the light guide 134 , the side wall 1346 of the light guide 134 has at least two recesses 1348 , and along the first direction, the side wall 1346 of the light guide 134 has at least two recesses 1348 ; wherein the first direction is the direction from the infrared component 130 to the light-transmitting element 120 .

[0082] Specifically, Fig.10 and Fig.11 As shown, the recess 1348 is an annular structure, that is, the recess 1348 surrounds the side wall 1346 of the entire light guide 134, and along the first direction, the side wall 1346 of the light guide 134 has at least two recesses 1348, that is, along the first direction, the light guide 134 has multiple layers of recesses 1348, so that light can be reflected on at least two recesses 1348, and then more light can be totally reflected on the surface of the light-transmitting member 120, thereby ensuring the energy of the evanescent wave and ensuring the normal use of the infrared remote control function.

[0083] Or, if Fig.12 and Fig.13 As shown, along the circumference of the light guide 134, the side wall 1346 of the light guide 134 has at least two protrusions 1344, that is, along the circumference of the light guide 134, the inside of the light guide 134 has at least two protrusions 1344, and along the first direction, the side wall 1346 of the light guide 134 has at least two recesses 1348, that is, along the first direction, the inside of the light guide 134 has multiple layers of recesses 1348, so that light can be reflected on at least two recesses 1348, and then more light can be totally reflected on the surface of the light transparent member 120, thereby ensuring the energy of the evanescent wave and ensuring the normal use of the infrared remote control function.

[0084] The first direction is the direction from the infrared component 130 to the light-transmitting element 120 .

[0085] That is, there are several recesses 1348 on the side wall 1346 of the light guide 134, which can change the path of the light emitted by the infrared light source 132, so that within the range of angles that the infrared light source 132 can emit, light at certain specific angles passes through the reflection path and is incident on the surface of the light-transmitting member 120 on the side away from the infrared light source 132 at an angle greater than or equal to the critical angle θc.

[0086] Furthermore, the surface of the recess 1348 may be a curved surface, a flat surface or an inclined surface. Of course, the surface of the protrusion 1344 may also be a combination of at least two of the curved surface, the flat surface and the inclined surface.

[0087] The recess 1348 can be processed by etching, injection molding, or grinding.

[0088] like Fig.14 , Fig.15 , Fig.16 and Fig.17 As shown, as a possible implementation, the light guide member 134 has at least one light guide surface 1350 therein.

[0089] Specifically, the light guide member 134 has at least one light guide surface 1350 therein, and the light changes its propagation direction through reflection by the light guide surface 1350 , so as to achieve a total reflection effect on the side of the light-transmitting member 120 facing away from the infrared component 130 .

[0090] The light guide surface 1350 may be made of glass, plastic, resin or metal, etc. The light guide surface 1350 may be disposed in the light guide component 134 by way of an insert.

[0091] As a possible implementation, Fig.14 and Fig.15 As shown, the light guide surface 1350 is an annular structure, and along the first direction, the interior of the light guide member 134 has at least two light guide surfaces 1350; or as shown Fig.16 and Fig.17 As shown, along the circumference of the light guide 134 , the light guide 134 has at least two light guide surfaces 1350 inside, and along the first direction, the light guide 134 has at least two light guide surfaces 1350 inside; wherein the first direction is the direction from the infrared component 130 to the light-transmitting element 120 .

[0092] Specifically, Fig.14 and Fig.15As shown, the light guiding surface 1350 is a ring-shaped structure, that is, the light guiding surface 1350 surrounds the entire light guiding member 134, and along the first direction, the interior of the light guiding member 134 has at least two light guiding surfaces 1350, that is, along the first direction, the light guiding member 134 has multiple layers of light guiding surfaces 1350, so that light can be reflected on at least two light guiding surfaces 1350, and more light can be totally reflected on the surface of the light-transmitting member 120, thereby ensuring the energy of the evanescent wave and ensuring the normal use of the infrared remote control function.

[0093] Or, if Fig.16 and Fig.17 As shown, along the circumference of the light guide 134, there are at least two light guiding surfaces 1350 in the light guide 134, that is, along the circumference of the light guide 134, there are at least two light guiding surfaces 1350 inside the light guide 134, and along the first direction, there are at least two light guiding surfaces 1350 inside the light guide 134, that is, along the first direction, there are multiple layers of light guiding surfaces 1350 inside the light guide 134, so that light can be reflected on at least two light guiding surfaces 1350, and then more light can be totally reflected on the surface of the light transparent member 120, thereby ensuring the energy of the evanescent wave and ensuring the normal use of the infrared remote control function.

[0094] The first direction is the direction from the infrared component 130 to the light-transmitting element 120 .

[0095] That is, there are several light-guiding surfaces 1350 on the inside of the light guide 134, which can change the path of the light emitted by the infrared light source 132, so that within the range of angles that the infrared light source 132 can emit, light at certain specific angles can pass through the reflection path and be incident on the surface of the light-transmitting member 120 on the side away from the infrared light source 132 at an angle greater than or equal to the critical angle θc.

[0096] Furthermore, the surface of the light guide surface 1350 may be a curved surface, a flat surface or an inclined surface. Of course, the surface of the protrusion 1344 may also be a combination of at least two of the curved surface, the flat surface and the inclined surface.

[0097] As a possible implementation manner, the light-transmitting member 120 is any one of the following: a screen protection glass, a battery cover, and a camera protection cover.

[0098] Specifically, the light-transmitting member 120 may be a screen protective glass of the screen assembly of the electronic device 100, that is, the outermost layer of the screen assembly. The screen assembly includes a laminated structure such as a copper foil layer, a circuit layer, a polarizing layer, and a protective glass. The light-transmitting member 120 may be the outermost protective glass.

[0099] The light-transmitting member 120 may also be a battery cover of the electronic device 100 , and the battery cover may be made of glass, plastic, or high molecular polymer.

[0100] The light-transmitting member 120 may also be a camera protection cover of the electronic device 100 , and the camera protection cover may be made of glass, plastic, or high molecular polymer.

[0101] The electronic device 100 may be a terminal, or may be another device other than the electronic device 100. For example, the electronic device 100 may be a mobile phone, a tablet computer, a laptop computer, a PDA, a music player, a private network communication terminal device (such as a walkie-talkie), a mobile Internet device (Mobile Internet Device, MID), an augmented reality / virtual reality / mixed reality device, a robot, a wearable device, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a netbook or a personal digital assistant (personal digital assistant, PDA), etc., and the embodiments of the present application are not specifically limited.
