[0051] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0052] Embodiment 1

[0053] This embodiment provides an electronic device 100a. Figure 1 and Figure 6 The electronic device 100a includes a housing 10, a light source 30 and an infrared light excitation layer 50 (see Figure 4A and Figure 4B). Wherein, the shell 10 includes a accommodating cavity 11, and the light source 30 is accommodated in the accommodating cavity 11. The light source 30 includes a first infrared light source 311, and the first infrared light source 311 is used to emit a first infrared light L1. The infrared light excitation layer 50 includes a first infrared light excitation layer 51, and the first infrared light excitation layer 51 is used to be excited by the first infrared light L1 and emit a first visible light L2. Specifically, the light source 30 also includes a visible light source 33, and the visible light source 33 is used to emit a second visible light L3. The shell 10 also includes a first light-transmitting portion 10a and a second light-transmitting portion 10b, and the first light-transmitting portion 10a and the second light-transmitting portion 10b do not overlap. The first infrared light excitation layer 51 is arranged on the first light-transmitting portion 10a and is located in the accommodating cavity 11. More specifically, the first light-transmitting portion 10a and the second light-transmitting portion 10b are both made of a light-transmitting material, the first light-transmitting portion 10a is used to emit the first visible light L2, and the second light-transmitting portion 10b is used to emit the second visible light L3. In other words, the first light-transmitting portion 10a is used to allow the first visible light L2 to pass through, and the second light-transmitting portion 10b is used to allow the second visible light L3 to pass through.

[0054] In this embodiment, the first infrared light source 311 corresponds to the first light-transmitting portion 10a, and the visible light source 33 corresponds to the second light-transmitting portion 10b. The first infrared light source 311 directly irradiates the first infrared light excitation layer 51, and the first infrared light L1 is not refracted by other light-guiding media (such as light-guiding columns, light-shielding plates, etc.) or transmitted to the first light-transmitting portion 10a, which simplifies the light-guiding structure and reduces light loss. At the same time, the first light-transmitting portion 10a and the second light-transmitting portion 10b are both light-transmitting materials. Specifically, when the visible light passes through the first light-transmitting portion 10a and the second light-transmitting portion 10b, it can be transmitted out and seen by the user. Optionally, the light-transmitting material includes polycarbonate (PC) material. At the same time, in addition to the first light-transmitting portion 10a and the second light-transmitting portion 10b, the remaining area of ​​the housing 10 that has no light-transmitting requirement can be made of acrylonitrile-butadiene-styrene (ABS) material.

[0055] In this embodiment, the housing 10 (see Figure 5 ) also includes a middle frame 13, a button 15 and a baffle set 17. Among them, the button 15 is installed on the middle frame 13, and the middle frame 13 is provided with a receiving hole 131 (see Figure 4A ) is used to place button 15. See Figure 2The button 15 includes a hollow main body 151 and a pressing portion 153 connected to one end of the main body 151, and the main body 151 and the pressing portion 153 are integrally formed into a cap-shaped structure. An optical channel 155 is formed in the main body 151. When the button 15 is installed on the middle frame 13, the main body 151 extends into the accommodating cavity 11 through the accommodating hole 131, and the pressing portion 153 is exposed to the outer surface of the shell 10, while the optical channel 155 is connected to the accommodating cavity 11. In addition, the baffle group 17 includes a first baffle 171 and a second baffle 173. The first baffle 171 and the second baffle 173 are respectively covered on the front and rear sides of the middle frame 13, and are used to be spliced ​​and assembled with the middle frame 13 to form a closed structure shell 10.

[0056] In this example, see Figure 2 , the light source 30 includes a plurality of light emitting diodes (LEDs), that is, the first infrared light source 311 includes an infrared light LED that emits infrared light, and the visible light source 33 includes a visible light LED that emits visible light. Specifically, the number of the visible light LED is one, and the number of the infrared light LEDs is three. The visible light LED and the infrared light LED have the same size, and the emission angle when emitting light is also the same and is 120°. The difference between the two is that they can emit light of different wavelengths. In other embodiments, the number of infrared light LEDs included in the first infrared light source 311, the number of visible light LEDs included in the visible light source 33, the size of the visible light LED and the infrared light LED, and the emission angle are not limited thereto, and the light source 30 is not limited to only including LEDs. In addition, the light source 30 also includes a substrate 35, and the first infrared light source 311 and the plurality of LEDs of the visible light source 33 are arranged on the side of the substrate 35 facing the key 15, and the plurality of LEDs are electrically connected to the circuit board 70 by means of the substrate 35. The end of the main body 151 of the button 15 away from the pressing part 153 is close to the visible light LED on the substrate 35, that is, the optical channel 155 connects the optical path between the visible light source 33 and the pressing part 153, so that the second visible light L3 emitted by the visible light source 33 passes through the optical channel 155 and is received by the pressing part 153.

[0057] In the present embodiment, the infrared light excitation layer 50 includes an infrared light excitation luminescent material attached to the light-transmitting area of ​​the inner surface of the shell 10, that is, the first infrared light excitation layer 51 includes an infrared light excitation luminescent material. For example, the infrared light excitation luminescent material includes an organic infrared light excitation luminescent material. In the present embodiment, when the first infrared light L1 is irradiated to the first infrared light excitation layer 51, the first infrared light excitation layer 51 emits the first visible light L2. Specifically, taking the luminescence of the first infrared light excitation layer 51 as an example, when the first infrared light L1 is irradiated to the first infrared light excitation layer 51, the first infrared light L1 is absorbed by the first infrared light excitation layer 51 and energy transfer occurs, and the first infrared light excitation layer 51 absorbs energy and undergoes energy level transition to a higher energy level to reach an excited state; then, when the first infrared light excitation layer 51 transitions back to a lower energy level or a ground state energy level, it releases energy, thereby emitting the first visible light L2, that is, generating a light-stimulated luminescence phenomenon.

[0058] In this embodiment, the second light-transmitting portion 10b is located on the key 15. Specifically, the second light-transmitting portion 10b is disposed on the pressing portion 153 and constitutes a part of the pressing portion 153. In this embodiment, the second light-transmitting portion 10b includes two arrow patterns connected end to end. In other embodiments, the pattern of the second light-transmitting portion 10b can be set to other identification patterns as needed. The first light-transmitting portion 10a is disposed on the middle frame 13 to form a part of the middle frame 13, and the first infrared light excitation layer 51 is disposed on the inner surface 133 of the middle frame 13 (see FIG. Figure 4A and Figure 4B ). Specifically, the first light-transmitting portion 10a includes an annular structure surrounding the accommodating hole 131, and also includes a character pattern structure that does not overlap with the annular structure (the character pattern structure in the figure is shown as "Reset"), and the first infrared light excitation layer 51 and the first light-transmitting portion 10a overlap in position, that is, the first infrared light excitation layer 51 completely and just covers the annular structure and the character pattern structure. In addition, the main body 151 of the key 15 is opaque. When the first infrared light source 311 and the visible light source 33 of the light source 30 both emit light, the main body 151 can be used to block the second visible light L3 in the optical channel 155 from entering the optical path area of ​​the first infrared light L1, reducing the mutual interference of the optical paths of the first infrared light source 311 and the visible light source 33, that is, the optical path through the first light-transmitting portion 10a and the optical path through the second light-transmitting portion 10b are independent of each other in the optical path.

[0059] In this embodiment, when the pressing portion 153 of the button 15 is not pressed, the end of the body 151 away from the pressing portion 153 is separated from the substrate 35. When the pressing portion 153 of the button 15 is pressed, the body 151 moves toward the substrate 35 and presses the switch button 157. At this time, the body 151 may contact the substrate 35 or be close to the substrate 35. When there is a gap G between the body 151 and the substrate 35, part of the first infrared light L1 emitted by the first infrared light source 311 can enter the optical channel 155 through the gap G after being reflected in the housing 10. Due to the invisibility of infrared light to the naked eye, even if the first infrared light L1 enters the optical path area of ​​the second visible light L3 in the optical channel 155, the first infrared light L1 will not cause visible interference to the luminous effect of the second visible light L3, that is, the luminous effects of the first infrared light source 311 and the visible light source 33 on the corresponding first light-transmitting portion 10a and the second light-transmitting portion 10b respectively do not cross-talk.

[0060] In this embodiment, the electronic device 100a has different types of light-emitting structures (first infrared light source 311 and visible light source 33) and corresponding light-transmitting structures (first light-transmitting portion 10a and second light-transmitting portion 10b), and displays different light-emitting modes in different working states. When the first infrared light source 311 and visible light source 33 and their corresponding first infrared light source 311 and visible light source 33 cooperate with each other, four different light-emitting modes can be displayed. Specifically, the first light-emitting mode is that the first infrared light source 311 emits light and the visible light source 33 does not emit light, so that the first light-transmitting portion 10a emits the first visible light L2 and displays the corresponding logo, while the second light-transmitting portion 10b does not emit light; the second light-emitting mode is that the first infrared light source 311 does not emit light and the visible light source 33 emits light, so that the first light-transmitting portion 10a does not emit light and the second light-transmitting portion 10b emits the second visible light L3 and displays the corresponding logo; the third light-emitting mode is that both the first infrared light source 311 and the visible light source 33 emit light, so that both the first light-transmitting portion 10a and the second light-transmitting portion 10b emit light and display the corresponding logo; the fourth light-emitting mode is that neither the first infrared light source 311 nor the visible light source 33 emits light, so that neither the first light-transmitting portion 10a nor the second light-transmitting portion 10b displays the corresponding logo.

[0061] In this example, see Figure 3 The electronic device 100a further includes a circuit board 70, which is accommodated in the accommodating cavity 11. Meanwhile, the light source 30 is fixedly arranged on a side of the circuit board 70 facing the inner surface 133 of the middle frame 13, and the circuit board 70 is used to control and drive the light source 30 to emit light, specifically, respectively control and drive the first infrared light source 311 and the visible light source 33 to emit light.

[0062] In addition, the key 15 further includes a switch button 157, which is close to one end of the body 151 away from the pressing portion 153 and in contact with the body 151. The switch button 157 is disposed on the side of the circuit board 70 where the light source 30 is located, and the key 15 is electrically connected to the circuit board 70 by means of the switch button 157. When the pressing portion 153 is pressed toward the direction where the accommodating cavity 11 is located, the body 151 also presses the switch button 157 at the same time. When the switch button 157 is pressed, the switch button 157 is used to switch the working state of the electronic device 100a and execute a specific function, which is indicated by the identification pattern on the second light-transmitting portion 10b.

[0063] Embodiment 2

[0064] The present application embodiment also provides an electronic device 100b. Figures 7 to 9 The difference between the electronic device 100b and the electronic device 100a of the first embodiment is that the visible light source 33 in the light source 30 is replaced by a second infrared light source 313, and the second infrared light source 313 is used to emit a second infrared light L4; optionally, the visible light LED in the visible light source 33 is replaced by an equal number of infrared light LEDs. The infrared light excitation layer 50 also includes a second infrared light excitation layer 53, which is disposed on the second light-transmitting portion 10b and located in the accommodating cavity 11. Specifically, the second infrared light excitation layer 53 is located on the side of the pressing portion 153 facing the second infrared light source 313, and the second infrared light excitation layer 53 coincides with the second light-transmitting portion 10b.

[0065] In this embodiment, the second infrared light L4 is located in the optical channel 155, the second infrared light excitation layer 53 is used to be excited by the second infrared light L4 to emit the third visible light L5, and the second light-transmitting portion 10b is used to emit the third visible light L5. In other words, the second light-transmitting portion 10b is used to allow the third visible light L5 to pass through.

[0066] In this embodiment, the pressing portion 153 may be made of a light-transmitting material, and the second light-transmitting portion 10 b specifically includes two arrow patterns connected end to end, and the second infrared light excitation layer 53 overlaps with the arrow patterns.

[0067] In this embodiment, the electronic device 100b has different types of light-emitting structures (first infrared light source 311 and second infrared light source 313) and corresponding light-transmitting structures (first light-transmitting portion 10a and second light-transmitting portion 10b), and displays different light-emitting modes in different working states. When the first infrared light source 311 and second infrared light source 313 and their corresponding first infrared light source 311 and second infrared light source 313 cooperate with each other, four different light-emitting modes can be displayed. Specifically, the first light-emitting mode is that the first infrared light source 311 emits light and the second infrared light source 313 does not emit light, so that the first light-transmitting part 10a emits the first visible light L2 and displays the corresponding logo while the second light-transmitting part 10b does not emit light; the second light-emitting mode is that the first infrared light source 311 does not emit light and the second infrared light source 313 emits light, so that the first light-transmitting part 10a does not emit light and the second light-transmitting part 10b emits the third visible light L5 and displays the corresponding logo; the third light-emitting mode is that both the first infrared light source 311 and the second infrared light source 313 emit light, so that the first light-transmitting part 10a and the second light-transmitting part 10b both emit light and display the corresponding logo; the fourth light-emitting mode is that neither the first infrared light source 311 nor the second infrared light source 313 emits light, so that neither the first light-transmitting part 10a nor the second light-transmitting part 10b displays the corresponding logo.

[0068] In the present embodiment, when the pressing portion 153 of the button 15 is not pressed, the end of the body 151 away from the pressing portion 153 is separated from the substrate 35. When the pressing portion 153 of the button 15 is pressed, the body 151 moves toward the substrate 35 and presses the switch button 157. At this time, the body 151 may contact the substrate 35 or be close to the substrate 35. When there is a gap G between the body 151 and the substrate 35, part of the first infrared light L1 emitted by the first infrared light source 311 may enter the optical channel 155 through the gap G after being reflected in the housing 10. Due to the invisibility of infrared light to the naked eye, the luminous effects of the first infrared light excitation layer 51 and the second infrared light excitation layer 53 will not produce visible interference to the naked eye, that is, the luminous effects of the first infrared light source 311 and the second infrared light source 313 on the corresponding first light-transmitting portion 10a and the second light-transmitting portion 10b, respectively, do not cross-talk.

[0069] In this embodiment, the first infrared light source 311 and the second infrared light source 313 are disposed on the circuit board 70 with the aid of the substrate 35 and are electrically connected to the circuit board 70. The circuit board 70 is used to respectively control and drive the first infrared light source 311 and the second infrared light source 313 to emit light.

[0070] In the above two embodiments, the electronic device (100a, 100b) can adopt a spraying method to form the infrared light excitation layer 50 during assembly. The spraying method can quickly form the infrared light excitation layer 50 on the first light-transmitting portion 10a and / or the second light-transmitting portion 10b, and make the infrared light excitation layer 50 evenly distributed and the brightness difference will not be too large when showing light. The average thickness of the infrared light excitation layer 50 is in the order of micrometers, specifically in the range of 20μm to 30μm. In addition, the spraying method is also more flexible, and the spraying area can be arbitrarily controlled.

[0071] The electronic device (100a, 100b) provided in the embodiment of the present application utilizes the characteristic that infrared light is invisible to the naked eye, and the characteristic that infrared light can excite the infrared light excitation layer to emit visible light after being irradiated by the infrared light, and uses the first infrared light source 311 to emit the first infrared light L1 and display light in combination with the first infrared light excitation layer 51. The electronic device (100a, 100b) is provided with the first infrared light excitation layer 51 on the first light-transmitting part 10a that emits the first visible light L2. Due to the invisibility of the first infrared light L1 to the naked eye, the influence of the first infrared light source 311 on other light-transmitting parts (such as the second light-transmitting part 10b) can be reduced, and the mutual interference of the optical paths of the first light-transmitting part 10a and other light-transmitting parts can be reduced. Based on this, the electronic device (100a, 100b) can avoid the problem of light crosstalk between the light-emitting effects of different light-transmitting parts including the first light-transmitting part 10a, and finally effectively improve the light-guiding efficiency. The electronic device (100a, 100b) having such advantages can be widely used in the electrical, electronic, and communication industries, for example, as a router, a computer, a television, and the like.

[0072] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
