DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described in the description of the embodiments of the present application in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application.

[0038] In the description of the embodiments of the present application, the words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or having more advantages than other embodiments or design solutions. In fact, the words such as "exemplary" or "for example" are used in the sense of presenting related concepts in a specific manner.

[0039] Figure 1 The application scenario diagram of the visualization panel in the related art.

[0040] In the related art, the visualization panel 200 is provided with a shell 300, a plurality of light emitting elements 500, and a plurality of light guide structures 600. The shell 300 is provided with a plurality of light transmission portions 301 corresponding to the light emitting elements 500, which can be a hole structure or a light transmission material structure, etc. The light guide structure 600 is arranged between the light transmission portion 301 of the shell 300 and the corresponding light emitting element 500. When the light emitting element 500 emits light, the light guide structure 600 receives the light of the light emitting element 500 and guides the light to the light transmission portion 301, so that a user can observe the light emitting state of the light transmission portion 301 from the outside of the shell 300.

[0041] However, since the light guide structure 600 is made of transparent plastic material and has the characteristic of being transparent throughout, part of the light may leak from the side of the light guide structure 600 during the process of receiving and propagating the light from the light emitting element 500, causing the light to easily occur between the adjacent plurality of light guide structures 600.

[0042] For example, between two adjacent light emitting elements 500, when one of the light emitting elements 500 emits light, one of the light guide structures 600 propagates the light to one of the light transmission portions 301, causing one of the light transmission portions 301 to light up, and part of the light of one of the light guide structures 600 may propagate to the other light guide structure 600 from the side, indicating that the other light transmission portion 301 appears weakly lighted, affecting the light emitting stability.

[0043] Therefore, the present application provides a light guide assembly and a visualization panel, which have the effect of improving the light emitting stability.

[0044] Figure 2 The structure schematic diagram of the visualization panel in the embodiments of the present application. Figure 3 The structure schematic diagram of the front view of the light guide assembly in the first embodiment of the present application.

[0045] As shown in Figure 2 and Figure 3 , the present application first provides a light guide assembly 100, which is applied to a visual panel 200. The visual panel 200 can include a housing 300, a substrate 400, light emitting elements 500, and the light guide assembly 100, the number of light emitting elements 500 is greater than or equal to 2, the housing 300 is provided with a plurality of light transmission parts 301 corresponding to the light emitting elements 500, the light emitting elements 500 and the light guide assembly 100 are both arranged on the substrate 400, and the substrate 400 is fixed to the housing 300. The light guide assembly 100 is arranged between the plurality of light emitting elements 500 and the corresponding light transmission parts 301, and is used to receive light from the light emitting elements 500 and guide the light to the corresponding light transmission parts 301 for a user to observe the light emitting state of the light transmission parts 301.

[0046] The visual panel 200 provided by the present application can be applied to an electronic device, and the light emitting state of each light transmission part 301 of the visual panel 200 can be used to indicate the working state of the electronic device.

[0047] In the examples of the present application, the electronic device can be applied to a photovoltaic system, and the electronic device can be a photovoltaic inverter device. The photovoltaic inverter device can feed back different working states through each light transmission part 301 of the visual panel 200. For example, each light transmission part 301 can include first, second, and third light transmission holes that are distributed at intervals, wherein the first light transmission hole is used to feed back the power-on / off state of the photovoltaic inverter device, the second light transmission hole is used to feed back the connection state of the photovoltaic inverter device with other devices, and the third light transmission hole is used to feed back whether the photovoltaic inverter device is faulty. It can be understood that the specific structure of the visual panel 200 can also be set according to the actual application scene, for example, the number and distribution of the light transmission parts 301 can be set, other configurations (such as touch buttons, display modules, etc.) of the visual panel 200 can be set, and the installation position of the visual panel 200 can be set, etc. The present application does not limit this.

[0048] Figure 4 Structure diagram of the back view of the light guide assembly of the first embodiment of the present application.

[0049] As shown in Figure 2 , Figure 3 and Figure 4 , the light guide assembly 100 includes a fixed plate 10, a light guide column 20, and a light shielding piece 30. The number of light guide columns 20 is greater than or equal to 2, and a plurality of light guide columns 20 are arranged at intervals on the fixed plate 10. The first end 21 of the light guide column 20 is used to be connected with the light emitting element 500, and the second end 22 of the light guide column 20 points to the light transmission part 301 corresponding to the light emitting element 500. The light shielding piece 30 is arranged on the side surface of the light guide column 20, and the light shielding piece 30 is used to shield the propagation of light.

[0050] Exemplarily, the fixing plate 10 is fixedly connected to the base plate 400, and the light guide columns 20 are fixed to the fixing plate 10, and the positions of the plurality of light guide columns 20 correspond to the positions of the plurality of light emitting elements 500 respectively. In the example of the present application, the number of the light guide columns 20 is 2; in other examples, the number of the light guide columns 20 can also be greater than 2, which can be configured according to the number of the light emitting elements 500.

[0051] The light guide column 20 is made of transparent plastic material, and the two ends of the light guide column 20 form a first end 21 and a second end 22 respectively. The first end 21 of the light guide column 20 is close to the corresponding light emitting element 500 to be connected with the light emitting element 500, and the second end 22 of the light guide column 20 is close to the light-transmitting part 301 of the shell 300 corresponding to the light emitting element 500. The light emitted by each light emitting element 500 can directly enter the corresponding light guide column 20 and propagate to the corresponding light-transmitting part 301 under the light guide action of the corresponding light guide column 20.

[0052] The light shielding member 30 is made of light shielding material, and is located on the side of the light guide column 20 to prevent the light from propagating from the side of the light guide column 20 to the light guide column 20. In this way, only the light from the corresponding light emitting element 500 is allowed to propagate from the first end 21 of the light guide column 20 to the light guide column 20, and the light from other light emitting elements (such as other light emitting elements 500 or adjacent other light guide columns 20) is prevented from affecting the light of the light guide column 20.

[0053] It can be understood that, in the process of the light emitted by the light emitting element 500 passing through the corresponding light guide column 20 and propagating to the corresponding light-transmitting part 301, the light shielding member 30 is used to shield the light, so as to prevent the light inside the light guide column 20 from propagating from the side to the outside of the light guide column 20, and to prevent the light outside the light guide column 20 from propagating from the side to the light guide column 20, thereby effectively reducing the light cross phenomenon between the adjacent plurality of light guide columns 20 and improving the light emitting stability.

[0054] It is worth noting that the structures of the plurality of light guide columns 20 in the example of the present application can be completely consistent, or there can be some inconsistent structures (such as different inner surface shapes), as long as each light guide column 20 can cooperate with the light shielding member 30.

[0055] Figure 5 The exploded view of the light guide assembly of the first embodiment of the present application.

[0056] As Figure 2 and Figure 5As shown, in an embodiment, the fixing plate 10 is made of transparent plastic material, the fixing plate 10 and the plurality of light guide columns 20 are integrally formed, so that the plurality of light guide columns 20 are fixedly connected to the fixing plate 10, the first end 21 of the light guide column 20 extends in the direction close to the light emitting element 500 on one side of the fixing plate 10, and the second end 22 of the light guide column 20 protrudes from the other side of the fixing plate 10 to the light transmission part 301. The fixing plate 10 and the light guide column 20 are integrally connected, and the light guide column 20 does not need to be fixed to the fixing plate 10 by other mounting structure, which simplifies the processing technology and reduces the material cost. In other embodiments, the fixing plate 10 and the light guide column 20 can also be connected in a split manner, for example, the light guide column 20 is inserted into the fixing plate 10 and is adhesively fixed to the fixing plate 10.

[0057] Further, the fixing plate 10 is provided with a groove part 11, the groove part 11 is arranged between the adjacent plurality of light guide columns 20, and the groove part 11 is used for blocking the propagation of light. For example, the groove part 11 is formed by inwardly recessing the surface of the fixing plate 10, the groove part 11 forms a stepped fault structure inside the fixing plate 10, which blocks the light transmission between the positions close to the two sides of the groove part 11 of the fixing plate 10; in other embodiments, the groove part 11 can also be a through groove structure, that is, it penetrates through both surfaces of the fixing plate 10, so as to achieve the effect of blocking light.

[0058] It can be understood that, since the fixing plate 10 has a certain light transmission, when the light emitting element 500 emits light to the corresponding light guide column 20, part of the light may be transmitted to the adjacent light guide column 20 through the part of the fixing plate 10 close to the light emitting element 500, and the groove part 11 has a blocking effect on this part of the light, which further reduces the light cross phenomenon between the adjacent plurality of light guide columns 20.

[0059] In an embodiment, the light guide column 20 is arranged in the light propagation direction of the light emitting element 500 as a whole, that is, the length direction of the light guide column 20 is parallel to the light propagation direction of the light emitting element 500. One end of the light guide column 20 connected to the fixing plate 10 forms the second end 22, and the other end of the light guide column 20 away from the fixing plate 10 forms the first end 21.

[0060] In an embodiment, the inner surface of the light guide column 20 is preferably a concave light scattering structure, so as to improve the light transmission effect.

[0061] In an embodiment, the light shielding part 30 is located on the side of the corresponding light guide column 20 facing the adjacent light guide column 20. In this way, the light shielding part 30 can effectively prevent the propagation of light between the sides of the adjacent plurality of light guide columns 20.

[0062] Figure 6 For Figure 3 A partial schematic view along the section of A-A line.

[0063] AsFigure 2 and Figure 6 As shown in FIG. 1, in an embodiment, the light shielding member 30 is in the shape of a sleeve as a whole. The light shielding member 30 is provided with a receiving groove 31 extending through both ends of the light shielding member 30, and the light guide column 20 is received in the receiving groove 31. In this way, the light shielding member 30 is sleeved on the light guide column 20 to achieve a comprehensive light shielding effect, and both ends of the light guide column 20 are exposed at both ends of the light shielding member 30, respectively, so as to be respectively connected with the light emitting element 500 and the light transmitting part 301. In addition, the overall length of the light shielding member 30 is greater than the length of the light guide column 20 exposed to the fixing plate 10, so that a space is left between the end of the light shielding member 30 away from the fixing plate 10 and the first end 21 of the light guide column 20 for accommodating the light emitting element 500.

[0064] In an embodiment, the light shielding member 30 is detachably connected with the light guide column 20. In this way, it is convenient for the user to disassemble and replace the light shielding member 30 and the light guide column 20.

[0065] Specifically, a clamping structure is arranged between the light shielding member 30 and the light guide column 20, and the light shielding member 30 and the light guide column 20 are detachably connected through the clamping structure, so as to improve the disassembly efficiency of the light shielding member 30 and the light guide column 20.

[0066] For example, the clamping structure includes a clamping block 32 and a clamping part 25. The clamping block 32 is arranged on the groove wall of the receiving groove 31, and the clamping part 25 is arranged on the side surface of the light guide column 20. The clamping block 32 and the clamping part 25 are clamped in cooperation in the length direction of the light guide column 20, so as to relatively fix the light shielding member 30 and the light guide column 20.

[0067] When it is needed to install the light shielding member 30 on the light guide column 20, the light shielding member 30 can be sleeved on the first end 21 of the light guide column 20, and the light shielding member 30 is pushed towards the second end 22 of the light guide column 20, so that the clamping block 32 and the clamping part 25 are clamped through interference fit. When it is needed to disassemble the light shielding member 30 from the light guide column 20, the light shielding member 30 can be pulled towards the first end 21 of the light guide column 20, so that the clamping block 32 and the clamping part 25 are separated through interference fit.

[0068] In an embodiment, the clamping block 32 is formed by protruding from the groove wall of the receiving groove 31, the clamping part 25 is a clamping groove formed by recessing the side surface of the light guide column 20, and the clamping block 32 is matched with the clamping part 25. The clamping block 32 is received in the clamping part 25 and abuts against the groove wall of the clamping part 25 in the length direction of the light guide column 20, so as to realize clamping cooperation.

[0069] In an embodiment, the number of the clamping portions 25 is greater than or equal to 2, and the plurality of clamping portions 25 are spaced apart around the circumference of the light guide column 20. The number and distribution of the clamping blocks 32 correspond to those of the clamping portions 25. For example, the number of the clamping portions 25 is 2, and the two clamping portions 25 are oppositely arranged on the side surface of the light guide column 20. The number of the clamping blocks 32 is 2, and the positions of the two clamping blocks 32 correspond to those of the two clamping portions 25. In this way, the plurality of clamping blocks 32 can be clamped with the plurality of clamping portions 25, respectively, to improve the connection stability of the light shielding member 30 and the light guide column 20.

[0070] Figure 7 An exploded view of the light guide column and the light shielding member of the first embodiment of the present application.

[0071] As shown in Figure 6 and Figure 7 In an embodiment, the light shielding member 30 is provided with a clearance 33, which is arranged on the side of the clamping block 32 and communicates with the light shielding member 30. For example, the two sides of each clamping block 32 are provided with the clearance 33, which penetrates the inner side and the outer side of the light shielding member 30 and penetrates one end of the light shielding member 30 along the side surface of the clamping block 32. By arranging the clearance 33, the deformation range of the part of the light shielding member 30 close to the clamping block 32 can be increased, so that the clamping block 32 deforms more easily when it is in interference fit with the clamping portion 25, and the user can conveniently install or dismount the light shielding member 30.

[0072] Figure 8 A distribution diagram of the plurality of light guide columns of the first embodiment of the present application.

[0073] As shown in Figure 7 and Figure 8 Further, the side surface of the light guide column 20 has a first surface 23 and a second surface 24. The first surface 23 of the light guide column 20 faces the adjacent light guide column 20, and the clamping portion 25 is arranged on the second surface 24, so that the clearance 33 is arranged on the second surface 24. For example, the cross section of the light guide column 20 is rectangular (the cross section direction is perpendicular to the length direction of the light guide column 20), and the circumferential side of the light guide column 20 forms four side surfaces. Among the four side surfaces, the side surface facing the other light guide column 20 forms the first surface 23, and the remaining side surfaces form the second surface 24. In this embodiment, two oppositely arranged light guide columns 20 are taken as an example, i.e., the side surfaces of the two light guide columns 20 facing each other are the first surface 23. It can be understood that the number or distribution of the light guide columns 20 can be changed, and the distribution of the first surface 23 and the second surface 24 can also be changed adaptively.

[0074] In another aspect, the circumferential side of the light guide column 20 is bent to form four side surfaces in the present embodiment. In other embodiments, the circumferential side of the light guide column 20 can be continuously distributed (for example, the cross section of the light guide column 20 is in the shape of a waist, and the cross section direction is perpendicular to the length direction of the light guide column 20), so that the circumferential side of the light guide column 20 forms four regions. The side surface in the four regions that faces the other light guide column 20 forms the first surface 23, and the remaining side surfaces in the four regions form the second surface 24.

[0075] It can be understood that, in the case where the light guide column 20 is not sleeved with the light shielding piece 30, the first surface 23 of the light guide column 20 is prone to light leakage with the adjacent other light guide column 20, and the second surface 24 of the light guide column 20 is not prone to light leakage with the adjacent other light guide column 20. In the present embodiment, the light shielding piece 30 is distributed on the second surface 24, so that the light shielding piece 30 completely shields the first surface 23, thereby preventing the light from interfering with the light guide column 20 through the accommodation opening 33.

[0076] In an embodiment, the inner side of the light shielding piece 30 is correspondingly arranged in the shape of the circumferential side of the light guide column 20, so that the light shielding piece 30 is positioned and matched with the light guide column 20 in the circumferential direction of the light guide column 20.

[0077] For example, the cross section of the light guide column 20 is in the shape of a rectangle (the cross section direction is perpendicular to the length direction of the light guide column 20), the circumferential side of the light guide column 20 forms four side surfaces, and an included angle is formed between two adjacent side surfaces. The shape of the light shielding piece 30 is adapted to the shape of the light guide column 20, so that the inner side of the light shielding piece 30 also forms four side surfaces, and an included angle is formed between two adjacent side surfaces. When the light shielding piece 30 is sleeved on the light guide column 20, the inner side of the light shielding piece 30 is parallel to the circumferential side of the light guide column 20. In other embodiments, the cross section of the light guide column 20 can also be in other shapes (for example, the shape of a waist, and the cross section direction is perpendicular to the length direction of the light guide column 20), and the shape of the light shielding piece 30 is adaptively modified to correspond to the light guide column 20, as long as the positioning and matching effect between the light guide column 20 and the light shielding piece 30 can be achieved.

[0078] The circumferential side of the light guide column 20 and the inner side of the light shielding piece 30 are matched with each other to limit the displacement of the light shielding piece 30 and the light guide column 20 in the circumferential direction. On the one hand, the clamping block 32 and the clamping portion 25 can be aligned to prevent the light shielding piece 30 from being incorrectly assembled or from being ineffective in cooperation. On the other hand, the displacement of the accommodation opening 33 to the first surface 23 to cause light leakage of the first surface 23 can be prevented.

[0079] In one embodiment, the opening area of the receiving groove 31 near one end of the fixed plate 10 is larger than the cross-sectional area (cross-sectional direction perpendicular to the length direction of the light guide column 20) of the first end 21 of the light guide column 20. For example, the light guide column 20 gradually shrinks in the direction away from the fixed plate 10, and the shape of the light shielding member 30 is matched with the shape of the light guide column 20. In this way, when the user sets the light shielding member 30 on the first end 21 of the light guide column 20, the first end 21 of the light guide column 20 can easily enter the receiving groove 31, which facilitates the user to install the light shielding member 30.

[0080] Figure 9 An exploded view of the light guide column and the light shielding member of the second embodiment of the present application. Figure 10 A cross-sectional view of the light guide column and the light shielding member of the second embodiment of the present application.

[0081] As shown in Figure 9 and Figure 10 , the difference between the present embodiment and the first embodiment includes that the light guide column 20 is uniformly distributed along the length direction of the light guide column 20, and the clamping portion 25 is a protruding structure formed by protruding from the surface of the light guide column 20. The clamping block 32 of the light shielding member 30 is arranged obliquely towards the inside of the light shielding member 30.

[0082] When the light shielding member 30 is set on the light guide column 20, the clamping portion 25 abuts against the clamping portion 25 along the length direction of the light guide column 20 to form a clamping fit, and at the same time, a gap is left between the inside of the light shielding member 30 and the circumferential side of the light guide column 20 to facilitate the disassembly of the light shielding member 30 from the light guide column 20.

[0084] As shown in Figure 2 , Figure 11 and Figure 12 , the difference between the present embodiment and the first embodiment includes that the light shielding member 30 includes a light shielding portion 40 and a bottom plate portion 50, the light shielding portion 40 is set on the light guide column 20, and the inside of the light shielding portion 40 forms the receiving groove 31. The bottom plate portion 50 is fixed to the light shielding portion 40. For example, the bottom plate portion 50 and the light shielding portion 40 are integrally formed, the bottom plate portion 50 is located at one end of the light shielding portion 40 close to the fixed plate 10, the bottom plate portion 50 is distributed along the outside of the light shielding portion 40, and the bottom plate portion 50 is parallel to the fixed plate 10; in other embodiments, the bottom plate portion 50 and the light shielding portion 40 can also be connected in a separate manner, for example, the bottom plate portion 50 and the light shielding portion 40 are fixed by adhesion.

[0085] The fixing plate 10 is provided with a mounting member 60 for mounting the bottom plate part 50. In this way, the fixing plate 10 is mounted and fixed with the bottom plate part 50 through the mounting member 60, so that the light shielding part 40 is fixed to the circumferential side of the light guide column 20, and the light shielding member 30 is fixed to the light guide column 20.

[0086] It is worth noting that, unlike the first embodiment, the light shielding member 30 in this embodiment does not need to be clamped with the light guide column 20, so it is not necessary to process a corresponding clamping structure on the light guide column 20, which guarantees the structural integrity of the light guide column 20, and further reduces the risk of light leakage of the light guide column 20 by not processing a displacement structure on the circumferential side of the light shielding member 30.

[0087] Figure 13 It is an exploded view of the light shielding member and the fixing plate of the third embodiment of the present application. Figure 14 It is a schematic view of the cooperation relationship between the mounting member and the bottom plate part of the third embodiment of the present application.

[0088] As shown in Figure 13 and Figure 14 In an embodiment, the mounting member 60 is mounted on the bottom plate part 50 in a non-detachable manner. For example, the bottom plate part 50 is provided with a positioning hole 51, which penetrates through both sides of the bottom plate part 50 along the thickness direction of the bottom plate part 50. The mounting member 60 is located on the side of the fixing plate 10 where the light guide column 20 is arranged, and extends along the length direction of the light guide column 20. The mounting member 60 is inserted into the positioning hole 51, one end of the mounting member 60 is fixed to the fixing plate 10, and the other end of the mounting member 60 is exposed from the positioning hole 51 and provided with a plug 61, which is fixed to the bottom plate part 50. For example, the cross-sectional area of the plug 61 is larger than that of the positioning hole 51 (the cross-sectional direction is perpendicular to the length direction of the mounting member 60), so that the plug 61 limits the bottom plate part 50 along the length direction of the mounting member 60, preventing the bottom plate part 50 from being separated from the fixing plate 10.

[0089] Specifically, the mounting member 60 is provided in plurality, and the plurality of mounting members 60 are distributed at intervals. The number and distribution of the positioning holes 51 are correspondingly arranged with the mounting members 60. The plurality of mounting members 60 are respectively matched with the plurality of positioning holes 51 through the plurality of plugs 61, which improves the mounting stability of the bottom plate part 50. At the same time, the plurality of mounting members 60 have a limiting effect on the bottom plate part 50 by being inserted into the corresponding positioning holes 51, preventing the bottom plate part 50 from being displaced and deviated.

[0090] In an embodiment, the mounting member 60 is made of a hot-melt material, so that the plug 61 can be formed by hot melting the end of the mounting member 60. For example, the mounting member 60 is made of plastic material and is integrally formed with the fixing plate 10; in other embodiments, the mounting member 60 and the fixing plate 10 can also be connected separately, for example, by bonding the mounting member 60 and the fixing plate 10.

[0091] When fixing the light-shielding component 30, the base plate 50 can be placed on the surface of the fixing plate 10, and the mounting component 60 can be inserted into the positioning hole 51. Then, the end of the mounting component 60 exposed in the positioning hole 51 can be heated by a heating tool (such as a welding machine) to heat-melt the end of the mounting component 60 to form a plug 61, thereby completing the fixing of the base plate 50 and improving the installation speed of the base plate 50.

[0092] Furthermore, the inner side of the positioning hole 51 gradually expands away from the fixing plate 10. For example, the inner diameter of the end of the positioning hole 51 away from the fixing plate 10 is larger than the inner diameter of the other end of the positioning hole 51. In this way, the filling space at the end of the mounting part 60 can be increased during heat fusion, which facilitates the user to heat fuse the mounting part 60, while increasing the overall volume of the plug 61 and improving the connection stability between the plug 61 and the base plate 50.

[0093] In one embodiment, multiple adjacent base plate portions 50 are fixedly connected. This embodiment takes two opposing light guide pillars 20 as an example, that is, the two base plate portions 50 are integrally connected, and multiple positioning holes 51 are distributed around the integral base plate structure formed by the two base plate portions 50; it can be understood that the number and distribution of positioning holes 51 can also be adaptively adjusted.

[0094] It is understandable that multiple adjacent light-shielding parts 40 form an integral light-shielding structure that can be simultaneously fitted onto multiple light guide pillars 20. During installation, the light-shielding structure of multiple light guide pillars 20 can be installed at the same time, improving installation efficiency.

[0095] Figure 15 This is a schematic diagram showing the fit between the mounting component and the base plate in the fourth embodiment of this application.

[0096] like Figure 15 As shown, the difference between this embodiment and the fourth embodiment includes: the plug 61 can be formed by applying adhesive to the end of the mounting part 60.

[0097] When fixing the light-shielding component 30, the base plate 50 can be placed on the surface of the fixing plate 10, and the mounting component 60 can be inserted into the positioning hole 51. Then, glue is applied to the end of the mounting component 60 exposed in the positioning hole 51 using a glue dispensing tool. The solidified glue forms a plug 61 and bonds the mounting component 60 to the base plate 50, thus fixing the base plate 50 and improving the installation stability of the base plate 50.

[0098] Figure 16 This is a schematic diagram showing the fit between the mounting component and the base plate in the fifth embodiment of this application.

[0099] like Figure 16As shown, the difference between the present embodiment and the third embodiment includes that the mounting member 60 is detachably mounted to the bottom plate 50. In this way, the user can conveniently dismount and replace the light shielding member 30 and the light guide column 20. For example, the mounting member 60 can be a mounting screw 62, and the fixed plate 10 is provided with a screw hole matched with the mounting screw 62.

[0100] When the light shielding member 30 is fixed, the bottom plate 50 can be placed on the surface of the fixed plate 10, so that the positioning hole 51 of the bottom plate 50 is in communication with the screw hole of the fixed plate 10, and then the mounting screw 62 is arranged in the positioning hole 51 and screwed into the screw hole, thereby completing the fixation of the bottom plate 50.

[0101] Figure 17 The exploded view of the light guide structure and the shell of the present embodiment is shown in the figure, taking the light guide structure of the first embodiment as an example.

[0102] As shown in Figure 3 and Figure 17 The present application also provides a visual panel 200, which can be applied to an electronic device. The visual panel 200 includes a shell 300, a substrate 400, a light emitting element 500, and the light guide assembly 100 of any one of the embodiments described above. The light guide assembly 100 includes a fixed plate 10, a light guide column 20, and a light shielding member 30. The number of light emitting elements 500 is greater than or equal to 2, and the shell 300 is provided with a plurality of light transmission portions 301 corresponding to the light emitting elements 500. The number, distribution, etc. of the light transmission portions 301 and the light emitting elements 500 can be configured according to actual needs. The light emitting element 500 and the light guide assembly 100 are both arranged on the substrate 400, and the substrate 400 is fixed to the shell 300.

[0103] For example, the shell 300 can be a shell structure of an electronic device. The shell 300 is provided with a through hole structure to form the light transmission portion 301. The substrate 400 is arranged opposite to the fixed plate 10, and the substrate 400 and the fixed plate 10 are parallel to each other with a spacing therebetween. The substrate 400 and the fixed plate 10 are fixed by a connecting column. The shell 300 is located on the side of the fixed plate 10 away from the substrate 400, and the shell 300 and the fixed plate 10 are spaced apart. The substrate 400 is fixed to the shell 300, so that the fixed plate 10 is fixed relative to the shell 300. The light emitting element 500 is welded to the side of the substrate 400 facing the fixed plate 10. The first end 21 of the light guide column 20 is close to the light transmission portion 301 corresponding to the light emitting element 500, and the second end 22 of the light guide column 20 is close to the light transmission portion 301 of the shell 300 corresponding to the light emitting element 500. The light emitted by each light emitting element 500 can directly enter each corresponding light guide column 20, and propagate to the corresponding light transmission portion 301 under the light guide action of the corresponding light guide column 20.
