AI Technical Summary
In the existing indicator light structure of electronic products, the direction of the LED patch light beam is not in a straight line with the axis of the light-transmitting hole, resulting in poor indicator light effect. At the same time, the large area of the hole damages the appearance integrity and is costly.
A light-transmitting sheet is used to set the light at an angle to the central axis of the light-transmitting hole, and a limiting structure is used to ensure the stable installation of the light-transmitting sheet. The light-transmitting sheet diffuses the light, and the ring ribs guide the light to concentrate and pass through, thus avoiding light leakage.
It enables flexible positioning of LED patch light rays, reduces space occupation, improves light source utilization, protects appearance integrity, and reduces costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of indicator light structures, and more specifically to an indicator light structure for an electronic device and the electronic device thereof. Background Technology
[0002] Indicator lights are common components in electronic products. Currently, LED surface-mount lights are commonly used to achieve the light indication function. The LED surface-mount light generally corresponds to the light emission hole. Existing electronic product indicator light structures have the following defects:
[0003] 1. Due to the inherent structural limitations of LED chip indicator lights, the light-emitting part is located above the circuit board. When the light-transmitting hole is located in front of the electronic product, the direction of the light from the LED chip indicator light on the circuit board is not in the same straight line as the axis of the light-transmitting hole, which causes the indicator light of the electronic product to fail to play a good lighting indication role.
[0004] 2. Existing electronic product front-end indicator lights use light-emitting diodes as the light source, which requires large holes to be made in the housing, thus compromising the integrity of the appearance. In addition, the light protection cover makes the indicator light structure occupy a lot of space, resulting in high cost. Utility Model Content
[0005] To solve the above problems, this utility model provides the following technical solution:
[0006] An indicator light structure for an electronic device includes a housing, a cavity inside the housing, and a light-transmitting hole on the housing. A PCB board is provided inside the cavity, and a light-emitting element is provided on the PCB board. The light emitted by the light-emitting element is angled to the central axis of the light-transmitting hole. A light-transmitting sheet is also provided inside the cavity, and the light emitted by the light-emitting element is diffused through the light-transmitting sheet and then transmitted through the light-transmitting hole.
[0007] The present invention is further configured such that: the outer shell includes an upper shell and a lower shell, the upper shell and the lower shell are fixedly connected to form the cavity, one of the light-transmitting sheet and the PCB board is disposed in the upper shell, and the other of the two is disposed in the lower shell, and the light-transmitting sheet covers the light-transmitting hole.
[0008] The present invention is further configured such that: the light-transmitting sheet is disposed inside the lower shell, the light-transmitting hole is disposed on the side wall of the lower shell, the front end of the light-transmitting sheet is provided with an insert block facing the light-transmitting hole, the insert block is provided with an annular groove for installing a waterproof sealing ring, the side wall of the lower shell is provided with an installation hole facing the light-transmitting hole, the installation hole is configured to communicate with the light-transmitting hole, and the insert block is sealed and inserted into the installation hole.
[0009] The present invention is further configured such that: a limiting rib is provided inside the lower shell, and a hook is provided on the light-transmitting sheet to cooperate with the limiting rib; the limiting rib and the hook are used to limit the light-transmitting sheet in the horizontal direction.
[0010] The present invention is further configured such that: the light-transmitting sheet has a stepped surface, and a limiting protrusion protrudes from the side wall of the lower shell, the limiting protrusion being attached to the stepped surface for limiting the vertical direction of the light-transmitting sheet.
[0011] The present invention is further configured such that: a guide groove is provided on the light-transmitting sheet, the guide groove extends along the axial direction of the light-transmitting hole, and a guide rib protrudes from the lower shell toward the guide groove, the guide rib sliding relative to the guide groove.
[0012] The present invention is further configured such that: a ring of ribs protrudes from the side of the light-transmitting sheet facing the light-emitting element, and the light-emitting element is positioned opposite to the cavity formed by the ring of ribs and is located directly above the cavity.
[0013] The present invention is further configured such that the light-transmitting sheet is made of a transparent or semi-transparent material.
[0014] The present invention is further configured such that the light emanating from the light-emitting element forms a 90° angle with the central axis of the light-transmitting hole.
[0015] In addition, this utility model also proposes an electronic device including the above-mentioned indicator light structure.
[0016] Compared with the prior art, the present invention has at least the following advantages:
[0017] 1. This application changes the existing technology by setting a light-transmitting sheet, which aligns the light-transmitting hole with the light source, i.e., the light source faces the light-transmitting hole directly. Instead, it uses a light-transmitting sheet to reflect and transmit light, allowing light to pass through the light-transmitting hole from any direction. This enables the use of LED chip lights as the light source while allowing for flexible setting of the light position. The structure is simple, occupies little space, and facilitates the optimization of the internal layout of the product.
[0018] 2. Through the cooperation of the limiting ribs and the hooks, when the light-transmitting sheet is installed, one side is in contact with the inner wall of the lower shell, and the other side is limited by the limiting ribs, thereby achieving horizontal limitation; through the cooperation of the limiting protrusions and the stepped surface, when the light-transmitting sheet is installed, the bottom is in contact with the lower shell, and the upper part of the stepped surface is blocked by the limiting protrusions, thereby achieving vertical limitation.
[0019] 3. By setting a ring of ribs on the side of the light-transmitting sheet facing the light-emitting element, a physical barrier is formed, which effectively blocks the leakage of light in non-target directions and guides the light more concentratedly into the interior of the light-transmitting sheet, thereby improving the utilization rate of the light source.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0028] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] An indicator light structure for an electronic device, such as Figure 1 and Figure 2As shown, the device includes an outer shell with a cavity 7 inside and a light-transmitting hole 6 on the outer shell. A PCB board 3 is housed within the cavity 7, and a light-emitting element 4 is mounted on the PCB board 3. The light emitted by the light-emitting element 4 is angled to the central axis of the light-transmitting hole 6. A light-transmitting sheet 5 is also provided within the cavity 7, allowing the light from the light-emitting element 4 to diffuse through the light-transmitting sheet 5 and then pass through the light-transmitting hole 6. By reflecting the light source through the light-transmitting sheet 5, the light-emitting element 4 can transmit light through the light-transmitting hole 6 even if it is not on the same straight line as the light source. The light-emitting element 4 can be an LED chip or an LED surface mount lamp. This embodiment uses an LED surface mount lamp. By using an LED surface mount lamp as the light source, the position of the light can be flexibly set, facilitating the optimization of the internal structure layout of the product.
[0030] In some embodiments, the light-emitting element 4 and the light-transmitting hole 6 are located on different horizontal planes (with the center plane of the light-transmitting hole as the boundary), specifically, the orientation of the light-emitting element 4 is perpendicular to the light-transmitting hole 6. The outer shell includes an upper shell 1 and a lower shell 2, which are fixed by snap-fit fasteners at the edges, or by screws, or a combination of snap-fit fasteners and screws. After the upper shell 1 and the lower shell 2 are fixedly connected, a cavity 7 is formed inside. One of the light-transmitting sheet 5 and the PCB board 3 is located on the upper shell 1, and the other is located on the lower shell 2. The light-transmitting sheet 5 covers the light-transmitting hole 6, so that light can be emitted through the light-transmitting hole 6 after passing through the light-transmitting sheet 5.
[0031] like Figures 3 to 5 As shown, in this embodiment, after the upper shell 1 and lower shell 2 are fixedly connected by a snap-fit, a cavity 7 is formed inside. The PCB board 3 is set on the upper shell 1, and the LED chip lights are set on the PCB board 3. Specifically, the PCB board 3 is fixed to the upper shell 1 by welding or screws, and the LED chip lights are welded to the PCB board 3. The light-transmitting sheet 5 is connected to the lower shell 2 by a snap-fit structure. The light-transmitting hole 6 is set on the side wall of the lower shell 2. The front end of the light-transmitting sheet 5 has an insert 11 facing the light-transmitting hole 6. The insert 11 and the light-transmitting sheet 5 are integrally formed. The insert has an annular groove 9 for installing a waterproof sealing ring 8. The side wall of the lower shell 2 has a mounting hole 10 facing the light-transmitting hole 6. The mounting hole 10 is connected to the light-transmitting hole 6, and the insert 11 and the mounting hole 11 are sealed and plugged in. By plugging the insert 11 with the waterproof sealing ring 8 into the mounting hole, water is prevented from entering the cavity 7 from the light-transmitting hole 6, which could damage the internal parts.
[0032] The lower shell 2 has a limiting rib 12 inside, and the light-transmitting sheet 5 has a hook 13 that cooperates with the limiting rib 12. The limiting rib 12 and the hook 13 are used to limit the horizontal movement of the light-transmitting sheet 5. The hook 13 is elastic. After the light-transmitting sheet 5 is installed, the insert block 11 is inserted into the mounting hole 10 and connected, with its front end fitting against the inner wall of the lower shell 2. At this time, the hook 13 is engaged with the limiting rib 12, so that the light-transmitting sheet 5 cannot move in the front-back direction. Stepped baffles 16 are also provided inside the lower shell 2 on the left and right sides of the light-transmitting sheet 5. When the light-transmitting sheet 5 is installed, the baffles 16 block it, so that the light-transmitting sheet 5 cannot move in the left and right direction either.
[0033] A stepped surface 14 is provided on one side of the front end of the light-transmitting sheet 5, and a limiting protrusion 15 protrudes from the side wall of the lower shell 2. The limiting protrusion 15 is attached to the stepped surface 14 to limit the vertical movement of the light-transmitting sheet 5. After the light-transmitting sheet 5 is installed, the bottom of the light-transmitting sheet 5 is attached to the lower shell 2 or to the lowest step of the baffle 16. At this time, the limiting protrusion 15 is attached to the step surface 14, so that the light-transmitting sheet 5 cannot move up or down, thus achieving vertical limitation.
[0034] A guide groove 17 is provided on the light-transmitting sheet 5, extending along the axial direction of the light-transmitting hole 6. A guide rib 18 protrudes from the lower shell 2 into the guide groove 17, and slides relative to the guide groove 17. Two guide grooves 17 are provided, symmetrically arranged on the left and right sides of the light-transmitting sheet 5, with the guide groove 17 located at the rear end of the light-transmitting sheet 5. Two guide ribs 18 are also correspondingly provided. The guide rib 18 is cylindrical, with its peripheral sidewalls fitting against the left and right sides of the inner wall of the guide groove 17. The light-transmitting sheet 5 can only be moved and installed along the axial direction of the light-transmitting hole 6. Before the light-transmitting sheet 5 is installed, the guide rib 18 is located at one end of the guide groove 17. When the insert block 11 of the light-transmitting sheet 5 moves to engage with the mounting hole 10 on the side wall of the lower shell 2 and covers the light-transmitting hole 6, the guide rib 18 moves to the other end of the guide groove 17.
[0035] A ring-shaped rib 19 protrudes from the side of the light-transmitting sheet 5 facing the light-emitting element 4. The light-emitting element 4 and the cavity formed by the ring-shaped rib 19 are positioned opposite each other and directly above the cavity. The light-transmitting sheet 5 is integrally molded. The ring-shaped rib 19 is integrally molded with the light-transmitting sheet 5 and forms a rectangle. The ring-shaped rib 19 forms a physical barrier. When the LED chip light shines downwards, it blocks the light from spreading in all directions, directing the light more concentratedly into the interior of the light-transmitting sheet 5, thus improving the utilization rate of the light source.
[0036] In this embodiment, the light-transmitting sheet 5 can be made of a transparent material or a semi-transparent material.
[0037] This embodiment also proposes an electronic device, including the indicator light structure of the above-mentioned electronic device. The electronic device can be a mobile phone, a remote control, etc. In this embodiment, the electronic device is a remote control. The light-transmitting hole 6 is opened at the front end of the remote control. The light of the LED chip lamp is diffused through the light-transmitting sheet 5 and emitted from the front end of the remote control.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
