Description

Technical Field

[0001] The utility model relates to the technical field of electronic device design, and particularly relates to a light anti-crossing structure and an electronic device. Background Art

[0002] Generally, electronic devices such as routers, switches, set-top boxes, etc. all have multiple indicator lights, and the working state of the electronic device is indicated according to the on or off of different indicator lights. Since the indicator lights of the electronic device are far from the product shell, a light guide component is usually matched to guide the light of the indicator lights to the surface of the product shell.

[0003] Currently, the light guide component mainly adopts two structural forms. The first structural form is that each indicator light is configured with a light guide column and a light-blocking member that does not conduct light; the second structural form is to combine the light guide bases of multiple indicator lights into an integral light guide base.

[0004] In the above first structural form, each indicator light is matched with a single light guide member and a light-blocking member. The number of parts is large and small, and the assembly is inconvenient and the cost is high.

[0005] The second structural form combines multiple light guide bases into an integral light guide base. During the assembly process, the integral light guide base is first inserted into the cavity reserved in the product shell, and then the light guide columns and light-blocking members are installed on the integral light guide base one by one. This structural form can save materials and simplify the assembly process to a certain extent, but there are still deficiencies:

[0006] For example, the light guide bases of two adjacent indicator lights are connected, which easily causes light to be emitted from the light guide column of another adjacent indicator light when one indicator light is on, that is, the so-called "light crossing" phenomenon in the industry occurs, resulting in the illusion that the remaining indicator lights are also lit, making it difficult for users to judge;

[0007] Therefore, finding a technical solution that can solve the above technical problems has become an important topic studied by those skilled in the art. Summary of the Utility Model

[0032] The embodiments of the present invention disclose a light leakage prevention structure and an electronic device, which are used to solve the technical problem that light leakage is likely to occur between multiple indicator lights on existing electronic devices.

[0033] To enable those skilled in the art to better understand the solution of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0034] Please refer to Figures 1 to 4 , a light leakage prevention structure provided by an embodiment of the present utility model includes a housing 1. A receiving cavity is provided inside the housing 1. A plurality of spaced and light-impermeable partition plates 101 are provided in the receiving cavity. The partition plates 101 and the housing 1 are of an integrally formed structure. Specifically, the partition plates 101 are specifically formed by extending downward from the top of the housing 1 to the receiving cavity. A light isolation cavity 102 is formed between two adjacent partition plates 101. An indicator light is placed in each light isolation cavity 102. A light outlet hole 103 is provided in the housing 1 at a position corresponding to the light isolation cavity 102. The area of the housing 1 around the light outlet hole 103 is a light-impermeable area;

[0035] The light leakage prevention structure further includes a light guide member 2. At least a part of the light guide member 2 is provided in the receiving cavity, and at least a part of the light guide member 2 faces or is inserted into the light outlet hole 103.

[0036] It should be noted that the receiving cavity in this embodiment is formed by recessing from the outer side surface of the housing 1 towards its interior.

[0037] In the above design, the light emitted when the indicator light is lit is blocked by the partition plate 101, and the light can only be emitted through the light guide member 2 from the light outlet hole 103 corresponding to the indicator light. Moreover, both the partition plate 101 and the area of the housing 1 around the light outlet hole 103 are made light-impermeable, effectively avoiding the phenomenon of light leakage between adjacent indicator lights.

[0038] Furthermore, the light guide member 2 and the housing 1 in this embodiment are of an integrally formed structure. Specifically, the housing 1 is a housing 1 made of plastic material, and the light guide member 2 is a light guide member 2 made of plastic material.

[0039] It should be noted that the light guide member 2 and the housing 1 are specifically combined into a whole by means of two-color injection molding. Through the above design, there can be zero clearance between the light guide member 2 and the housing 1, achieving dust and water protection. Without the need for waterproof parts such as waterproof gaskets, the waterproof performance of the entire light leakage prevention structure can be effectively improved, eliminating the need for the setting of waterproof gaskets and press-fitting fixing components, further simplifying the structure and reducing the occupied space. Therefore, the light guide member 2 can be set more compactly, and thus the limitation on the setting distance of the indicator lights is less.

[0040] Furthermore, the light guide member 2 in this embodiment includes a light guide base 201 and at least two light guide columns 202;

[0041] The plurality of light guide pillars 202 are disposed at intervals on the light guide base 201 and are disposed one-to-one correspondingly to the plurality of light exit holes 103;

[0042] The light guide column 202 is provided with a light input end 2023 and a light output end 2024. The light input end 2023 of the light guide column 202 is used to be set toward the indicator light in the assembled state, and the light output end 2024 of the light guide column 202 is directed toward or inserted in the light output hole 103. Specifically, the light output end 2024 of the light guide column 202 can be set in the air relative to the light output hole 103 or inserted in the light output hole 103 or exposed from the light output hole 103. This embodiment does not limit this. The light output end of the light guide column 202 can achieve external light guiding.

[0043] It should be noted that, through the above design, the light guide column 202 can effectively guide the light emitted by the indicator light. Specifically, when the indicator light is on, the light emitted by it enters the light guide column 202 and is emitted from the light output end of the light guide column 202.

[0044] See also Figure 4 , the light guide column 202 in this embodiment includes a column 2021 and a light guide head 2022 connected to the top of the column 2021;

[0045] The light guide head 2022 is oriented toward or inserted into the light exit hole 103. Specifically, the light guide head 2022 can be spaced apart from the light exit hole 103 or inserted into the light exit hole 103 or exposed from the light exit hole 103. This embodiment does not limit this. The light guide head 2022 can achieve external light guidance.

[0046] It should be noted that the cross section of the column 2021 in this embodiment is larger than the cross section of the light guide head 2022. With such a structural design, the light emitted by the indicator light can enter the light guide column 202 as much as possible. In addition, the above design can firstly allow the light to be gathered to the light guide head 2022 through the column 2021, forming a focusing effect, and the light is brighter and more concentrated; secondly, a shoulder surface can be formed at the connection between the column 2021 and the light guide head 2022 to provide a limit in the assembly structure, which helps to enhance the compactness of the internal structure.

[0047] Furthermore, the light guide base 201 and the light guide column 202 in this embodiment are an integrally formed structure.

[0048] It should be noted that the above design can reduce the assembly connections between parts, reduce the difficulty of assembly, effectively save installation time, and greatly improve production efficiency.

[0049] Further, to better solve the problem of light crosstalk, the housing 1 in this embodiment is specifically an opaque structure. To achieve the light guiding function, the light guiding member in this embodiment is a light transmissive structure.

[0050] Please refer to Figures 1 to 4 , an electronic device provided by an embodiment of the present utility model includes the above anti-light-crosstalk structure.

[0051] It should be noted that the electronic device in this embodiment can be a router, a switch, a set-top box, a speaker, etc., and this embodiment does not limit this.

[0052] Further, the electronic device in this embodiment further includes a PCB board and a plurality of indicator lights electrically connected to the PCB board;

[0053] The PCB board is disposed in the housing 1 of the anti-light-crosstalk structure, and the indicator lights are located in the light isolation cavity 102 of the anti-light-crosstalk structure.

[0054] Further, in some cases, to enable users to better judge various states of the electronic device, the display colors of the plurality of indicator lights in this embodiment are different from each other.

[0055] In the electronic device of this embodiment, the light emitted when the indicator light is lit is blocked by the partition 101, and the light can only pass through the light guiding member 2 from the light outlet hole 103 corresponding to the indicator light. Moreover, the partition 101 and the area of the housing 1 around the light outlet hole 103 are both made opaque, effectively avoiding the phenomenon of light crosstalk between adjacent indicator lights.

[0056] The above has introduced in detail an anti-light-crosstalk structure and an electronic device provided by the present utility model. For those of ordinary skill in the art, according to the idea of the embodiments of the present utility model, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present utility model.
