Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment indication, in particular to an indicator light display component and electronic equipment. Background Art

[0002] At present, indicator lights are widely used in electronic devices, and the traditional indicator light display method is: a through hole is opened on the shell of the electronic device, an LED (Light Emitting Diode) lamp is arranged in the shell, and the lamp head of the LED lamp is exposed outside the shell through the through hole for display. Because the entire LED lamp will emit light when the LED lamp is displayed, if no light shielding structure is added, problems such as light straying and light leakage often occur. At present, light shielding foam is usually used to press and fill the gap between the PCB board and the shell to separate the light path, thereby solving the problems of light straying and light leakage. However, for electronic device shells with assembly requirements, such as aluminum extruded hollow shells, during assembly, the circuit board needs to be pushed from the outside into the aluminum extruded hollow shell for assembly. During the pushing process, the inner side of the circuit board and the shell at the light-emitting position have relative movement. If the light shielding foam is filled between them to separate the light path, the foam will be deformed during the assembly process, and it is very easy to block the lamp beads, affecting the light effect.

[0019] In order to more fully understand the technical content of the present invention, the technical solution of the present invention is further introduced and illustrated below in conjunction with the schematic diagram, but is not limited thereto.

[0020] Reference Figures 1 to 4 , Figures 1 to 4A specific embodiment of the electronic device 100 of the utility model is shown. In the embodiment shown in the drawings, the electronic device 100 includes a housing 20, an indicator light 40, a circuit board 30 and an indicator light display assembly 10, wherein the circuit board 30 is arranged in the housing 20, the indicator light 40 is arranged on the circuit board 30, the indicator light display assembly 10 includes an elastic shading member 11 and a first shading member 12, the first shading member 12 is arranged on the circuit board 30 and covers the indicator light 40, the elastic shading member 11 is located above the first shading member 12, and its top end is attached to the inner wall of the housing 20, the elastic shading member 11 is provided with a penetrating light-transmitting through hole 111, the top of the first shading member 12 extends into the light-transmitting through hole 111, the housing 20 is provided with a light-emitting hole 21 at the position corresponding to the indicator light 40, so that the light of the indicator light 40 is emitted through the light-emitting hole 21, and one end of the elastic shading member 11 is open. In the utility model, the circuit board 30 can be a flexible printed circuit (FPC) or a printed circuit board. It can be understood that the circuit board 30 is usually made of materials such as copper foil, metal coating, solder mask ink, etc., and has a certain thickness. Therefore, it has a certain light-shielding ability. The light-shielding performance of circuit boards of different materials and thicknesses is different. Different circuit boards can be selected according to the intensity of the light emitted by the indicator light 40. The circuit board 30 supplies power to the indicator light 40. When powered on, the indicator light 40 emits light of preset intensity and color at a preset time, and can also block the light directly from the indicator light 40 to the circuit board 30. Based on the above design, the first shading member 12 is arranged on the circuit board 30 and covers the four sides of the indicator light 40. It is a closed shading structure connected to the circuit board 30, which can block the light emitted by the indicator light 40 to the four sides and retain the light emitted upward. The elastic shading member 11 is a semi-closed shading structure with an opening at one end, and it is connected to the inner wall of the shell 20. The top of the first shading member 12 extends into the elastic shading member 11, and the elastic shading member 11 can block the light at the gap between the side wall of the shell 20 and the first shading member 12, which can further reduce light leakage and light crosstalk to the greatest extent. The opening is convenient for pushing the first shading member 12 during assembly, and together constitute a double-layer shading structure, which can not only meet the assembly of the circuit board 30 in the shell 20 of certain electronic equipment, but also improve the display effect of the indicator light 40.

[0021] In the present invention, one or more indicator lights 40 may be provided according to specific light effect requirements. Figure 3 and Figure 4As shown, in this embodiment, two indicator lights 40 are arranged on the circuit board 30, and the first light shielding member 12 covers the outside of the two indicator lights 40. The indicator lights 40 can be optical devices such as light emitting diodes that can emit light, and can be monochromatic light sources or red, green and blue tricolor light sources, which are not limited in this embodiment of the utility model.

[0022] Continue to refer to Figures 2 to 4 In some embodiments, the indicator light display assembly 10 further includes a light-distributing member 13, the light-incident surface of the light-distributing member 13 faces the indicator light 40, and the light-emitting surface of the light-distributing member 13 protrudes from the top of the elastic light-shielding member 11 and is located in the light-emitting hole 21. Based on the above design, the light emitted by the indicator light 40 passes through the light-transmitting through hole 111 and then is emitted through the light-distributing member 13, so as to further improve the indication effect of the indicator light 40.

[0023] Preferably, in this embodiment, a buffer gap is provided between the light incident surface of the light evenly distributed member 13 and the indicator light 40 , so as to prevent the light evenly distributed member 13 from squeezing the indicator light 40 and damaging the indicator light 40 when an external force is applied.

[0024] In some embodiments, the elastic shading member 11 is a shading foam. In order to avoid the occurrence of cross-light phenomenon as much as possible, the shading foam can be made of dark plastic particles. In the utility model, the elastic shading member 11 has a certain elasticity, so it is easier to stably set between the inner wall of the shell 20 and the first shading member 12. In order to fill the gap between the inner wall of the shell 20 and the first shading member 12 as much as possible to prevent light leakage, the elastic shading member 11 can be attached to the inner wall of the shell 20 by means of tape or glue, so as to fit the inner wall of the shell 20 as much as possible. For example, the elastic shading member 11 can be attached to the inner wall of the shell 20 by adhesive backing.

[0025] In some embodiments, the first light shielding member 12 is a light shielding silicone. In order to better avoid the phenomenon of light crosstalk, the first light shielding member 12 is as close to the circuit board 30 as possible, and the first light shielding member 12 and the circuit board 30 can be connected by means of tape and / or glue. Specifically, in this embodiment, when the first light shielding member 12 is installed, it can be pre-fixed by back glue, and then a circle of black AB glue is applied to the bottom of the four side walls that are closely attached to the circuit board 30, so as to ensure the light shielding effect while fixing the first light shielding member 12 and the circuit board 30.

[0026] Furthermore, a first gap 50 is provided between the side wall of the first shading member 12 and the side wall of the elastic shading member 11 to facilitate the push-in assembly of the first shading member 12; and a second gap 60 is provided between the side wall of the first shading member 12 and the two indicator lights 40. The first shading member 12 does not contact the indicator lights 40, thereby realizing an air-avoiding design of the indicator lights 40, which can improve the heat dissipation of the indicator lights 40 and avoid safety problems that may be caused by overheating of the indicator lights 40.

[0027] In summary, the indicator light display assembly in the electronic device of the utility model is provided with an elastic shading member and a first shading member, and the elastic shading member and the first shading member constitute a double-layer shading structure to achieve the shading effect, that is, the first shading member is arranged on the circuit board and covers the surrounding of the indicator light, and is a closed shading structure connected to the circuit board, which can block the light emitted by the indicator light to the surroundings and retain the light emitted upward, and the elastic shading member is a semi-closed shading structure with an open end, and it is connected to the inner wall of the shell, and the top of the first shading member extends into the elastic shading member. The elastic light-shielding member can block the light at the gap between the side wall of the shell and the first light-shielding member, which can further reduce light leakage and light crosstalk to the greatest extent. The elastic light-shielding member has an opening at one end, and the first light-shielding member has a certain distance from the inner wall of the electronic device shell, which is conducive to the push-in assembly of the first light-shielding member, so that it and the elastic light-shielding member together form a double-layer light-shielding structure, and the indicator light will not be blocked due to the deformation of the first light-shielding member. It can meet the assembly of circuit boards in the shell of some electronic equipment, and is convenient for establishing light shielding in shells with assembly requirements, avoiding light leakage and light crosstalk, and improving the display effect of the indicator light.
