Abstract
Description
Technical Field
[0001] This application relates to the technical field of electronic devices, and particularly relates to a light guide structure and an electronic device. Background Art
[0002] The indicator lights on a circuit board are generally divided into plug-in LEDs and surface-mounted LEDs. The plug-in LEDs are soldered to the circuit board through pins, and the pins are erected or bent at 90° to limit the height, so that the heads of the plug-in LEDs protrude from the panel. Users can understand the operating state of the electronic device by observing the color display of the plug-in LEDs. However, the plug-in LEDs are supported by two pins and are very easy to deform, with poor stability; moreover, the application of the plug-in LEDs is also relatively limited, and their height is limited by the length of the pins and cannot be used once it exceeds its effective height.
[0003] The surface-mounted LEDs are directly attached to the surface of the circuit board and have good stability; moreover, the surface-mounted LEDs are used in conjunction with a light guide structure to adapt to different heights. The light guide structure includes a plurality of light guide columns and a light-shielding member. The light guide columns can guide the light emitted by the surface-mounted LEDs from the circuit board to the panel or other positions, and the light-shielding member is used to separate two adjacent light guide columns to prevent light leakage between two adjacent light guide columns. The common light guide structure is generally fixed on the circuit board with screws, resulting in low assembly efficiency of the light guide structure. Summary of the Utility Model
[0004] In view of this, embodiments of this application provide a light guide structure and an electronic device to solve the problem of low assembly efficiency of the existing light guide structure.
[0005] A first aspect of this application proposes a light guide structure for being fixed on a circuit board, including:
[0006] A light-shielding member having a plurality of light-shielding grooves;
[0007] A plurality of light guide columns, with a plurality of the light guide columns respectively arranged in the plurality of light-shielding grooves;
[0008] A plurality of connecting columns, with the connecting columns arranged on one side of the light-shielding member and / or the light guide columns facing the circuit board. A plurality of tooth portions are provided on the outer wall surface of the connecting columns. A slot extending along its axial direction is opened at the middle position of the connecting columns, and the connecting columns are press-fitted into the fixing holes of the circuit board.
[0009] The beneficial effects of the light guide structure provided by the embodiment of the present application are as follows: since a slot extending along the axial direction is provided in the middle of the connecting column, the parts of the connecting column located on both sides of the slot have a certain elastic force; during assembly, the connecting column is inserted into the fixing hole of the circuit board with interference fit, and the parts of the connecting column located on both sides of the slot are elastically deformed so that the multiple teeth abut against the hole wall of the fixing hole, so that the connecting column is not easy to fall out of the fixing hole of the circuit board, thereby ensuring the stability of the light guide structure fixed on the circuit board. Moreover, the light guide structure can be fixed on the circuit board by simply inserting the connecting column into the fixing hole of the circuit board, thereby improving the assembly efficiency of the light guide structure.
[0010] In some embodiments, fixing glue is filled between two adjacent teeth.
[0011] The beneficial effect of adopting the above technical solution is that on the basis that the parts of the connecting column located on both sides of the groove abut against the hole wall of the fixing hole, the connecting column is bonded in the fixing hole by fixing glue, further ensuring that the connecting column is not easy to fall out of the fixing hole of the circuit board.
[0012] In some embodiments, the shading member, the plurality of light guide pillars, and the plurality of connecting pillars are integrally injection molded.
[0013] The beneficial effects of adopting the above technical solution are as follows: this can not only reduce costs and improve production efficiency, but also improve the overall structural strength and dimensional accuracy of the light guide structure.
[0014] In some embodiments, the light guide column is made of transparent PMMA, and / or the light shielding member is made of black PBT.

[0017] The beneficial effect of adopting the above technical solution is that the light-guiding structure can guide light to multiple rows of indicator lights while preventing cross-lighting, so that the electronic device can display more indicator light information.
[0018] In some embodiments, the light guide column includes a main body section and an inserting section for inserting into a plug hole on a panel, and an inserting direction of the inserting section is perpendicular to an inserting direction of the connecting column.
[0019] Advantages of adopting the above technical solution: Usually, the circuit board is horizontally arranged, that is, the light emitted by the indicator light is vertical. The insertion direction of the insertion section is perpendicular to the insertion direction of the connection column, realizing the turning of the light and making the light emit horizontally. In this way, the panel can face the operator, which is beneficial for the operator to observe the indicator light information.
[0020] In some embodiments, the light guide column includes a main body section and an insertion section for inserting into a jack on the panel, and the width of the insertion section is smaller than the width of the main body section.
[0021] Advantages of adopting the above technical solution: The width of the insertion section is smaller than the width of the main body section, which can converge the light and further improve the light guiding effect.
[0022] In some embodiments, one end face of the insertion section far from the main body section is a rectangular face.
[0023] Advantages of adopting the above technical solution: The end face of the insertion section is a rectangular face, which can improve the injection molding yield, and the light emitting area of the rectangular face is larger, making it easier to identify visually.
[0024] In some embodiments, the light guide column further includes a connection section provided on a side surface of the main body section facing the circuit board, the connection column is provided on the connection section, and the connection section, the main body section and the light shielding member enclose a receiving groove for receiving the lamp beads on the circuit board.
[0025] In a second aspect of the present application, an electronic device is proposed, and the electronic device includes the light guiding structure as described in the first aspect.

[0056] An embodiment of the first aspect of the present application provides a light guide structure. Please refer to Figure 2 、 Figure 5 and Figure 6 , the light guide structure 10 includes a light shielding member 11, light guide columns 12 and connecting columns 13. The light shielding member 11 has a plurality of light shielding grooves 111; a plurality of light guide columns 12 are provided, and the plurality of light guide columns 12 are respectively arranged in the plurality of light shielding grooves 111; a plurality of connecting columns 13 are provided and arranged on one side of the light shielding member 11 or the light guide columns 12 facing the circuit board 20. A plurality of tooth portions 131 are provided on the outer wall surface of the connecting column 13, and a slot 132 extending along its axial direction is opened at the middle position of the connecting column 13. The connecting column 13 is press-fitted into the fixing hole 22 of the circuit board 20.
[0057] The light shielding member 11 functions to shield light, so that light leakage does not occur between the two light guide columns 12 in adjacent two light shielding grooves 111, ensuring that the operator can accurately judge the indicator information.
[0058] In the present application, the shape of the light shielding groove 111 is not limited, as long as it can meet the light shielding of the light guide column 12. Among them, the light shielding groove 111 can be provided in one row or multiple rows; when the light shielding groove 111 is provided in multiple rows, the adjacent two rows of light shielding grooves 111 can be arranged in alignment or in a staggered manner.
[0059] The function of the light guide column 12 is to conduct the light emitted by the indicator lamp 21 on the circuit board 20 to the panel 30 for the operator to observe the indicator information, that is, to judge the operating state of the electronic device 100 according to the different colors displayed by the indicator lamp 21.
[0060] The plurality of light guide columns 12 are respectively arranged in the plurality of light shielding grooves 111, which can be understood as that one light guide column 12 is provided in each light shielding groove 111. Among them, the shape of the light guide column 12 is not limited in the present application, as long as it can conduct the light emitted by the indicator lamp 21 on the circuit board 20 to the panel 30.
[0061] The connecting posts 13 are provided on one side of the light-shielding member 11 and / or the light guide column 12 facing the circuit board 20. It can be understood that multiple connecting posts 13 can all be provided on the side of the light-shielding member 11 facing the circuit board 20; or, multiple connecting posts 13 can be respectively provided on the sides of multiple light guide columns 12 facing the circuit board 20; or, some connecting posts 13 are provided on the side of the light-shielding member 11 facing the circuit board 20, and some connecting posts 13 are provided on the side of the light guide column 12 facing the circuit board 20.
[0062] A plurality of tooth portions 131 are provided on the outer wall surface of the connecting post 13. It can be understood that a plurality of tooth portions 131 can all extend along the axial direction of the connecting post 13; or, a plurality of tooth portions 131 can also all extend along the circumferential direction of the connecting post 13; or, a plurality of tooth portions 131 can also extend in other directions.
[0063] A slot 132 extending along its axial direction is formed at the middle position of the connecting post 13. Optionally, in the axial direction of the connecting post 13, the slot 132 extends from one end of the connecting post 13 to the other end of the connecting post 13, and the slot 132 penetrates in the radial direction of the connecting post 13.
[0064] Optionally, a chamfer is provided at the insertion end of the connecting post 13 to facilitate guiding the connecting post 13 to be inserted into the fixing hole 22 of the circuit board 20.
[0065] Among them, the shape of the connecting post 13 is not limited in this application. For example, the connecting post 13 can be a cylinder, a prism, an elliptical cylinder, etc. Correspondingly, the fixing hole 22 can be a circular hole, a rectangular hole, an elliptical hole, etc.
[0066] The beneficial effects of the light guide structure 10 provided by the embodiments of this application: Since a slot 132 extending along its axial direction is formed at the middle position of the connecting post 13, therefore, the parts of the connecting post 13 on both sides of the slot 132 have a certain elasticity; during assembly, the connecting post 13 is press-fitted into the fixing hole 22 of the circuit board 20, and the parts of the connecting post 13 on both sides of the slot 132 undergo elastic deformation so that a plurality of tooth portions 131 abut against the hole wall of the fixing hole 22, making it difficult for the connecting post 13 to come out of the fixing hole 22 of the circuit board 20 and ensuring the stability of the fixation of the light guide structure 10 on the circuit board 20. Moreover, by simply inserting the connecting post 13 into the fixing hole 22 of the circuit board 20, the fixation of the light guide structure 10 on the circuit board 20 can be achieved, improving the assembly efficiency of the light guide structure 10.
[0067] In some embodiments, fixing glue is filled between adjacent two tooth portions 131.
[0068] When the multiple tooth portions 131 all extend along the axial direction of the connecting post 13, the fixing glue can be filled between two adjacent tooth portions 131 before the connecting post 13 is inserted into the fixing hole 22 of the circuit board 20, or the fixing glue can also be filled between two adjacent tooth portions 131 after the connecting post 13 is inserted into the fixing hole 22 of the circuit board 20; when the multiple tooth portions 131 all extend along the circumferential direction of the connecting post 13, the fixing glue needs to be filled between two adjacent tooth portions 131 before the connecting post 13 is inserted into the fixing hole 22 of the circuit board 20.
[0069] It can be understood that the fixing glue can be filled between any two adjacent tooth portions 131, or can also be filled between some two adjacent tooth portions 131.
[0070] On the basis that the portions of the connecting post 13 on both sides of the slot 132 abut against the hole wall of the fixing hole 22, the connecting post 13 is bonded in the fixing hole 22 through the fixing glue, further ensuring that the connecting post 13 is not easily disengaged from the fixing hole 22 of the circuit board 20.
[0071] In other embodiments, if after the connecting post 13 is inserted into the fixing hole 22 of the circuit board 20, the portions on both sides of its slot 132 have sufficient elasticity to ensure that the connecting post 13 is stably fixed in the fixing hole 22 of the circuit board 20, then the fixing glue may not be filled between two adjacent tooth portions 131.
[0072] In some embodiments, the light-shielding member 11, the multiple light guide posts 12 and the multiple connecting posts 13 are integrally injection-molded.
[0073] Optionally, the light guide post 12 is made of transparent PMMA (Polymethyl Methacrylate), and the transparent PMMA has a high light transmittance after injection molding, generally reaching more than 95%, so as to improve the light guiding effect; the light-shielding member 11 is made of black PBT (Polybutylene Terephthalate), and the black PBT has a high light-shielding property after injection molding, so as to improve the light-shielding property.
[0074] During injection molding, the materials used for the light-shielding member 11 and the light guide posts 12 are different. The two different materials are injection-molded into the same set of molds, and are simultaneously injection-molded at one time using a two-color injection molding machine, which reduces costs and improves production efficiency. In addition, since the two materials are melted and combined together by injection molding, the overall structural strength and dimensional accuracy of the light guiding structure 10 are improved.
[0075] It can be understood that the multiple connecting posts 13 can be respectively arranged on the multiple light guide posts 12, that is, the multiple connecting posts 13 are respectively formed together with the multiple light guide posts 12 during injection molding, and the connecting posts 13 and the light guide posts 12 are made of the same material. Alternatively, the multiple connecting posts 13 can also be arranged on the light shielding member 11, that is, the multiple connecting posts 13 are formed together with the light shielding member 11 during injection molding, and the connecting posts 13 and the light shielding member 11 are made of the same material.
[0076] In other embodiments, the shading member 11 and the light guiding column 12 can be formed separately and then fixed together; in this case, the connecting column 13 can be integrally formed on the shading member 11 and / or the light guiding column 12, and the connecting column 13 can also be fixed on the shading member 11 and / or the light guiding column 12.
[0077] Please also refer to Figure 4 , Figure 6 and Figure 7 In some embodiments, a plurality of light-shielding grooves 111 are arranged into a plurality of rows, and the light-shielding grooves 111 in each row are arranged at intervals along the first direction X; a plurality of light-guiding columns 12 are arranged into a plurality of rows, and the light-guiding columns 12 in each row are arranged at intervals along the first direction X and are disposed in each row of light-shielding grooves 111.
[0078] Optionally, the plurality of light shielding grooves 111 are arranged in two rows, and correspondingly, the plurality of light guide columns 12 are arranged in two rows, wherein each row of light guide columns 12 is provided with a row of connecting columns 13. Figure 2 and Figure 3 As shown, two rows of indicator lights 21 and two rows of fixing holes 22 are arranged on the circuit board 20 along the second direction Y, and the two rows of indicator lights 21 are located between the two rows of fixing holes 22; at the same time, two rows of sockets 31 are provided on the panel 30 along the third direction X, and optionally, the sockets 31 are rectangular holes.
[0079] Of course, the plurality of light-shielding grooves 111 may also be arranged in three or more rows, and correspondingly, the plurality of light-guiding columns 12 may be arranged in three or more rows.
[0080] By adopting the above technical solution, the light guide structure 10 can guide light to multiple rows of indicator lights 21 while preventing cross-lighting, so that the electronic device 100 can display more indicator light information.
[0081] In other embodiments, the plurality of light shielding grooves 111 may also be arranged in a row, and correspondingly, the plurality of light guiding pillars 12 may be arranged in a row.
[0082] Please also refer to Figure 3 , Figure 7 and Figure 8 In some embodiments, the light guide column 12 includes a main body section 122 and an inserting section 121 for inserting into the insertion hole 31 on the panel 30 , and the insertion direction of the inserting section 121 is perpendicular to the insertion direction of the connecting column 13 .
[0083] Among them, the insertion direction of the insertion section 121 is the second direction Y, and the insertion direction of the connecting column 13 is the third direction Z.
[0084] It can be understood that it is not absolute that the insertion direction of the insertion section 121 is perpendicular to the insertion direction of the connecting column 13. The insertion direction of the insertion section 121 can also be approximately perpendicular to the insertion direction of the connecting column 13.
[0085] Usually, the circuit board 20 is horizontally arranged, that is, the light emitted by the indicator light 21 is vertical. Making the insertion direction of the insertion section 121 perpendicular to the insertion direction of the connecting column 13 realizes the turning of the light, enabling the light to be emitted horizontally. In this way, the panel 30 can face the operator, which is beneficial for the operator to observe the indicator light information.
[0086] In other embodiments, the insertion direction of the insertion section 121 can be parallel to the insertion direction of the connecting column 13; or, the insertion direction of the insertion section 121 and the insertion direction of the connecting column 13 form a set angle, for example, 30°, 45°, 60°, etc.
[0087] Please refer to Figure 7 and Figure 8 . In some embodiments, the light guide column 12 includes a main body section 122 and an insertion section 121 for inserting into the jack 31 on the panel 30. The width of the insertion section 121 is smaller than the width of the main body section 122.
[0088] Among them, the width direction of the insertion section 121 and the width direction of the main body section 122 are both the first direction X.
[0089] Optionally, the width of the main body section 122 is about 3 mm, the width of the insertion section 121 is about 2 mm, and the width of the insertion section 121 is about 1 mm smaller than the width of the main body section 122.
[0090] The width of the insertion section 121 being smaller than the width of the main body section 122 can converge the light, further improving the light guiding effect.
[0091] In other embodiments, the width of the insertion section 121 can be equal to or greater than the width of the main body section 122.
[0092] Please refer to Figure 8 . In some embodiments, one end face of the insertion section 121 away from the main body section 122 is a rectangular face 1211.
[0093] By adopting the above technical solution, the end face of the insertion section 121 is the rectangular face 1211, which can improve the injection molding yield, and the light emitting area of the rectangular face 1211 is larger, making it easier to identify visually.
[0094] In other embodiments, the end face of the insertion section 121 away from the main body section 122 is a curved surface, for example, a spherical surface.
[0095] Please refer to Figure 4 , Figure 7 and Figure 8 , in some embodiments, the light guide column 12 further includes a connection section 123 provided on the side surface of the main body section 122 facing the circuit board 20. The connection post 13 is provided on the connection section 123. The connection section 123, the main body section 122, and the light-shielding member 11 enclose a receiving groove 14 for receiving the indicator light 21 on the circuit board 20.
[0096] Optionally, the indicator light 21 is a surface mount LED; generally, the surface mount LED is a rectangular structure. Correspondingly, the receiving groove 14 is a rectangular groove.
[0097] Optionally, two rows of the receiving grooves 14 are arranged along the second direction Y.
[0098] Please refer to Figures 1 to 3 , a second aspect of the present application provides an electronic device 100. The electronic device 100 includes the light guide structure 10 as in the first aspect.
[0099] Among them, the electronic device 100 further includes a circuit board 20 and a panel 30. The circuit board 20 is provided with an indicator light 21 and a fixing hole 22. The panel 30 is provided with a jack 31. The connection post 13 is inserted into the fixing hole 22 to fix the light guide structure 10 on the circuit board 20. At the same time, the main body section 122 of the light guide column 12 is arranged corresponding to the indicator light 21, and the insertion section 121 of the light guide column 12 is inserted into the jack 31.
[0100] Optionally, the insertion direction of the insertion section 121 is perpendicular to the insertion direction of the connection post 13, that is, the circuit board 20 is perpendicular to the panel 30. For example, the circuit board 20 is horizontally arranged and the panel 30 is vertically arranged. Of course, the insertion direction of the insertion section 121 can also be parallel to the insertion direction of the connection post 13, that is, the circuit board 20 is parallel to the panel 30. For example, both the circuit board 20 and the panel 30 are horizontally arranged; or, the insertion direction of the insertion section 121 can also form a set angle with the insertion direction of the connection post 13. For example, the circuit board 20 is horizontally arranged and the panel 30 is inclined.
