[0044] The shading device 1 is used to shade the light guide column 3 of the indicator light of electronic devices such as computers, mobile phones, routers, etc., reduce the light leakage caused by the light propagating outward from the side of the light guide column 3, and make the guided light more concentrated. The light in the light guide column 3 is provided by the light-emitting element 21, and the light-emitting element 21 is connected to the light-emitting circuit board 22. The shading device 1 needs to be able to wrap the light guide column 3 and the light-emitting element 21, and make a section of the light guide column 3 extend to the light-transmitting hole of the shell, so that the light can be emitted from the light-transmitting hole of the shell as the indicator light. The shell light-transmitting hole opened on the shell 4 can also limit the light guide column 3 to a certain extent, so the order of installation can be adjusted according to actual conditions. During actual installation, according to the product structure and requirements, the light guide column 3 can be placed first, and then the shading device 1 can be installed on its outside, and the light can be covered for shading; the shading device 1 can also be positioned to open it, and then the light guide column 3 is placed in the shading device 1, and then the shading device 1 is covered for shading.

[0045] The shading device 1 of the embodiment of the present application limits and blocks the light guide column 3 through the covering structure 11 and the supporting structure 12, and the hook 14 cooperates with the flexible structure 13 to realize the opening, closing and locking of the shading device 1, so that the shading device 1 can adapt to various installation scenarios and requirements, and does not require the coordination of multiple parts. It is easy to install and has a wide range of applicable scenarios.

[0046] Embodiment 1:

[0047] Reference Figure 1-Figure 2, the shading device 1 includes a bearing structure 12, a covering structure 11 and a hook 14. Among them, the bearing structure 12 is used to accommodate the light guide column 3, and the covering structure 11 and the bearing structure 12 are connected and rotated to open and close through the flexible structure 13, so as to surround the light guide column 3 and achieve the function of covering the light. The covering structure 11 and the bearing structure 12 cover each other to form a light hole 131 for the light guide column 3 to extend from one side, so that the light guide column 3 can guide the light out. In this embodiment, the light hole 131 is formed on one side of the flexible structure 13 and is arranged in a shape similar to the light guide column 3. There are two hooks 14, which are arranged on the bearing structure 12 and extend toward the covering structure 11, and the hook-shaped parts of the hooks 14 are arranged opposite to each other. At the same time, the hooks 14 are elastic, and the covering of the covering structure 11 and the bearing structure 12 is locked by the hooks 14, so that the shading device 1 can be opened and locked without the need for multiple parts to cooperate, and is easy to install and applicable to a wide range of scenarios.

[0048] In this embodiment, the light guide column 3 is placed in a horizontal direction, and the corresponding housing 4 is provided with a housing light-transmitting hole in a horizontal direction. Figure 1 The cover structure 11 of this embodiment includes a top plate 111 and a shielding edge 112. The top plate 111 shields the top surface of the light guide column 3. When the cover structure 11 covers the supporting structure 12, the top plate 111 is parallel to the supporting structure 12. According to actual conditions, the top plate 111 can also be set to be inclined. For example, the top plate 111 can be set to be inclined along the light propagation direction to adapt to the shape of the housing 4 and other external structures, such as Fig.10 As shown. The shielding edge 112 protrudes from the edge of the top plate 111. When the supporting structure 12 is covered with the covering structure 11, the shielding edge 112 shields the light-emitting element 21 and the light-guiding column 3. In other words, the shielding of the side of the light-guiding column 3 is achieved by the shielding edge 112. The light-emitting element 21 is located on the side of the light-guiding column 3 away from the light-through hole 131. When the covering structure 11 is covered with the supporting structure 12, the portion of the shielding edge 112 along the light propagation direction can also accommodate the light-emitting element 21 in the space formed by the covering structure 11 and the supporting structure 12, thereby achieving further light shielding.

[0049] Reference Figure 1-Figure 3 , the top plate 111 is provided with slots 113 on both sides perpendicular to the light propagation direction, and the hook 14 passes through the slots 113 and engages with the top surface of the top plate 111. The shielding edges 112 located on both sides of the top plate 111 extend to the side of the slot 113 away from the light-through hole 131 to avoid affecting the engagement of the hook 14 with the top plate 111. The height of the bottom surface of the hook 14 is substantially the same as the height of the top plate 111 after the covering structure 11 is covered, so that when the hook 14 is engaged with the top surface of the top plate 111, the bottom surface of the hook 14 contacts the top surface of the top plate 111, that is, the hook 14 can enable the shading device 1 to basically ensure a good shading effect. According to actual conditions, when the top plate 111 is tilted, such as Fig.10As shown, the bottom surface of the hook 14 is also adapted to be an inclined surface. Since the hook 14 is elastic, the horizontal cross-sectional area of ​​the slot 113 is actually smaller than the bottom cross-sectional area of ​​the hook 14. The top surface of the hook 14 has an inclined guide surface on the opposite side. When the covering structure 11 and the bearing structure 12 are covered, the slot 113 first contacts the hook 14 and causes the hook 14 to bend outward. As the covering structure 11 moves further downward, the bottom surface of the hook 14 is higher than the top surface of the top plate 111. At this time, the hook 14 is no longer pushed by the surface of the slot 113, and rebounds and completes the buckling, thereby locking the covering structure 11 and the bearing structure 12, so that the shading device 1 can be opened and locked without the need for multiple parts to cooperate. It is easy to install and has a wide range of applicable scenarios.

[0050] Reference Figure 1-Figure 3 , the shading device 1 also includes two side blocking structures 15, which are symmetrically arranged on both sides of the bearing structure 12 and are perpendicular to the bearing structure 12. In this embodiment, the side blocking structure 15 is arranged on the outside of the hook 14, and its shape is basically the same as the curved edge formed by the flexible structure 13 when the covering structure 11 and the bearing structure 12 are covered, and is used to block the part of the side of the light guide column 3 that is not blocked by the blocking edge 112. At the same time, its area will not exceed the edge formed by the flexible structure 13 too much, so as to avoid occupying too much space. In other words, the top plate 111, the blocking edge 112, the bearing structure 12, the flexible structure 13 and the side blocking structure 15 together constitute a shielding for the light guide column 3, so that the light of the light-emitting element 21 can only be emitted from the light-through hole 131, further improving the shading effect.

[0051] In this embodiment, if Figure 1-Figure 2 As shown, two symmetrically arranged positioning parts 16 are provided on the bearing structure 12, and positioning grooves 161 are provided on opposite sides of the two positioning parts 16. The light guide column 3 is placed between the two positioning parts 16, and the two positioning parts 16 position the light guide column 3 in the horizontal direction. For the horizontally placed light guide column 3 in this embodiment, positioning columns 31 are raised on both sides thereof perpendicular to the propagation direction of the light, and the light emitting direction of the light emitting element 21 is to emit light to one side of the light guide column 3 in the horizontal direction. When the light guide column 3 is placed between the two positioning parts 16, the two positioning columns 31 are inserted into the two positioning grooves 161 to achieve positioning.

[0052] Reference Figure 1-Figure 2, a first fixing portion 171 is protruded on the covering structure 11, and at least one second fixing portion 172 is protruded on the bearing structure 12. The first fixing portion 171 cooperates with the second fixing portion 172 to limit the light guide column 3 in the vertical direction. Since the light guide column 3 is arranged between the two positioning portions 16, at least one second fixing portion 172 is located between the two positioning portions 16 to support the bottom of the light guide column 3. According to actual conditions, the number of second fixing portions 172 can be one, two or more. The first fixing portion 171 is also arranged at a position between the two positioning portions 16. When the covering structure 11 and the bearing structure 12 are covered, the light guide column 3 is located between the second fixing portion 172 and the first fixing portion 171 and is limited. According to actual conditions, a fixing block can also be provided on the covering structure 11, and a corresponding fixing groove is opened on the bearing structure 12 to cooperate with it. When covering, the fixing block can enter the fixing groove to further limit the covering structure 11 and the bearing structure 12, thereby increasing the stability of the device.

[0053] The shading device 1 in this embodiment limits the light guide column 3 by the covering structure 11 and the bearing structure 12, wherein the positioning portion 16 and its positioning groove 161 limit the light guide column 3 in the horizontal direction, and the first fixing portion 171 and the second fixing portion 172 limit the light guide column 3 in the vertical direction. At the same time, the covering structure 11, the bearing structure 12 cooperate with the side blocking structure 15 and the flexible structure 13 to achieve shielding of the light guide column 3 in multiple directions. The hook 14 is engaged with the top plate 111 to further lock the shading device 1, so that the shading device 1 can adapt to a variety of installation scenarios and requirements, and does not require the coordination of a variety of parts, and is easy to install and applicable to a wide range of scenarios.

[0054] Embodiment 2:

[0055] Reference Figure 4 , the shading device 1 includes a bearing structure 12, a covering structure 11 and a hook 14, wherein the bearing structure 12 is connected to the covering structure 11 through a flexible structure 13. The bearing structure 12, the covering structure 11, the flexible structure 13 of this embodiment are basically the same as the bearing structure 12, the covering structure 11, the flexible structure 13 of the first embodiment, and the light guide column 3 is a light guide column 3 placed in the horizontal direction, which will not be repeated in this embodiment. The difference between this embodiment and the first embodiment is only the different positional relationship between the side blocking structure 15 and the hook 14, and the avoidance of the inner side of the top plate 111 in the covering structure 11 to the side blocking structure 15.

[0056] In this embodiment, if Figure 4-Figure 6As shown, the side block structure 15 is arranged on the inner side of the hook 14. At this time, when the covering structure 11 is covered with the bearing structure 12, the side block structure 15 enters the projection area of ​​the top plate 111. In other words, when the covering structure 11 is covered with the bearing structure 12, the side block structure 15 is located within the area wrapped by the covering structure 11 and the flexible structure 13, rather than being arranged outside the covering structure to occupy additional space. A first avoidance groove 115 for avoiding the side block structure 15 is provided on the inner side of the covering structure 11. According to actual conditions, the first avoidance groove 115 can be arranged on the lower surface of the top plate 111. When the side block structure 15 is covered, its top end can be avoided by the first avoidance groove 115, which reduces the gap between the side block structure 15 and the covering structure 11, and can better block the light.

[0057] Reference Figure 5 Since the positioning portion 16 is used for positioning and limiting, the side blocking structure 15 is arranged on the outside of the two positioning portions 16. That is to say, for each of the two sides perpendicular to the light transmission direction, the side blocking structure 15 is located between the hook 14 and the positioning portion 16, so that it can block the light without affecting the placement of the light guide column 3. According to actual conditions, a fixing block can also be provided on the covering structure 11, and a corresponding fixing groove can be opened on the bearing structure 12 to cooperate with it. When covering, the fixing block can enter the fixing groove to further limit the covering structure 11 and the bearing structure 12, thereby increasing the stability of the device.

[0058] The shading device in this embodiment limits the light guide column by means of the covering structure and the bearing structure, wherein the light guide column is limited in the horizontal direction by the positioning portion and its positioning groove, and the light guide column is limited in the vertical direction by the first fixing portion and the second fixing portion. At the same time, the covering structure, the bearing structure, the side blocking structure, and the flexible structure cooperate, and when covering, the top of the side blocking structure enters the first avoidance groove, reducing the gap between it and the covering structure, and effectively realizing the shielding of the light guide column in multiple directions. The hook and the top plate are buckled together to further realize the locking of the shading device, so that the shading device can adapt to a variety of installation scenarios and requirements, and does not require the coordination of a variety of parts, and is easy to install and applicable to a wide range of scenarios.

[0059] Embodiment three:

[0060] Reference Figure 7-Figure 9, the shading device 1 of the embodiment of the present application includes a bearing structure 12, a covering structure 11 and a hook 14. Among them, the bearing structure 12 is used to accommodate the light guide column 3, and the covering structure 11 and the bearing structure 12 are connected by a flexible structure 13 and rotated to open and close, so as to surround the light guide column 3 and achieve the function of covering the light. The covering structure 11 and the bearing structure 12 can cover each other to form a light hole 131 for the light guide column 3 to extend from one side, so that the light guide column 3 can guide the light out. In this embodiment, the light guide column 3 is a light guide column 3 placed in a vertical direction, and the light emitting direction of the light emitting element 21 is to emit light upward. The light hole 131 is formed by the covering structure 11 and the side of the bearing structure 12 away from the light emitting element 21, and is arranged in the same shape as the light guide column 3. There are two hooks 14, which are arranged on the bearing structure 12 and extend toward the covering structure 11. According to actual conditions, the hooks 14 can be arranged on the same side of the bearing structure 12, or on two sides perpendicular to each other on the bearing structure 12. The hook 14 is elastic, and the covering structure 11 and the bearing structure 12 are locked by the hook 14, so that the shading device 1 can be opened and locked without the need for multiple parts to cooperate. It is easy to install and has a wide range of application scenarios.

[0061] In this embodiment, the housing light-transmitting hole on the housing 4 is a housing light-transmitting hole in a vertical direction, which is in the same direction as the light guide column 3. Figure 7-Figure 8 , the covering structure 11 of this embodiment includes a top plate 111 and a shielding edge 112. The top plate 111 and the supporting structure 12 realize shielding of the end face of the light guide column 3, and the flexible structure 13 and the shielding edge 112 realize shielding of the side of the light guide column 3. When the covering structure 11 and the supporting structure 12 are covered, the top plate 111 is parallel to the supporting structure 12. The shielding edge 112 protrudes from the edge of the top plate 111, and the light-emitting element 21 is located on the side of the light guide column 3 away from the light-through hole 131. Since the light-emitting element 21 is connected to the light-emitting circuit board 22, according to actual conditions, a notch for avoiding the light-emitting element 21 can be opened on the shielding edge 112.

[0062] Reference Figure 7-Figure 8, a block 114 is protruded on the shielding edge 112, and the hook 14 is buckled with the block 114. The length of the inner plane of the hook 14 extending out of the bearing structure 12 is substantially the same as the distance between the top surface of the block 114 and the bearing structure 12, so that when the covering structure 11 covers the bearing structure 12, the top surface of the block 114 contacts the inner plane of the hook 14, that is, the hook 14 can basically ensure a good shading effect for the shading device 1. The top surface of the hook 14 has an inclined guide surface on one side facing the inner side of the bearing structure 12, and when the covering structure 11 covers the bearing structure 12, the shielding edge 112 first contacts the hook 14, and causes the hook 14 to bend outward. As the covering structure 11 moves further, the bottom surface of the hook 14 is higher than the top surface of the block 114. At this time, the hook 14 is no longer pushed by the shielding edge 112 and the side of the block 114, and rebounds and completes the engagement, thereby locking the covering structure 11 and the supporting structure 12.

[0063] In this embodiment, refer to Figure 7-Figure 9 , a first receiving groove 123 and a limiting clamp 124 are provided on the bearing structure 12, and a second receiving groove 117 and a second avoidance groove 118 are provided on the covering structure 11. The first receiving groove 123 cooperates with the second receiving groove 117, and is arranged in the shape of the light guide column 3, for accommodating the light guide column 3 and forming a light through hole 131 on one side. For the light guide column 3 arranged in the vertical direction, a positioning column 31 is protruded from its side, and according to actual conditions, its bottom can have a protruding shape of a square or the like. A positioning blind hole 121 is provided in the first receiving groove 123, and the number and position of the positioning blind holes 121 are the same as those of the light guide column 3. When the light guide column 3 is placed, the positioning column 31 of the light guide column 3 is arranged in the positioning blind hole 121.

[0064] Reference Figure 7-Figure 8 , the limit card 124 cooperates with the positioning blind hole 121 to limit the light guide column 3 together. According to actual conditions, the limit card 124 can be made into a buckle shape, and its curved part limits the bottom of the light guide column 3. Since the light guide column 3 is placed vertically in this embodiment, the positioning blind hole 121 and the limit card 124 cooperate to limit the light guide column 3 better. At the same time, since the limit card 124 is raised from the bearing structure 12, a second avoidance groove 118 is also opened at a position corresponding to the limit card 124 on the cover structure 11, which is used to avoid and accommodate the limit card 124.

[0065] In this embodiment, refer to Figure 7-Figure 8 A fixing block 116 is protruded on the covering structure 11, and a fixing groove 122 is opened on the supporting structure 12. The positions of the fixing block 116 and the fixing groove 122 correspond to each other, so that the connection between the covering structure 11 and the supporting structure 12 is tighter and stronger after covering.

[0067] Embodiment 4:

[0068] Reference Fig.11 , Fig.12 , the shading device 1 includes a bearing structure 12, a covering structure 11 and a hook 14, wherein the bearing structure 12 is connected to the covering structure 11 through a flexible structure 13. The bearing structure 12, the covering structure 11, the flexible structure 13 of this embodiment are basically the same as the bearing structure 12, the covering structure 11, and the flexible structure 13 of the first embodiment, and the light guide column 3 is a light guide column 3 placed in a horizontal direction, which will not be repeated in this embodiment. The only difference between this embodiment and the first embodiment is that a fixing hook 119 and a fixing block 116 are provided on the covering structure 11, and a fixing groove 122 corresponding to the fixing block 116 is provided on the bearing structure 12. The fixing hook 119 enables the covering structure 11 and the bearing structure 12 to be covered by the engagement between the hook 14 and the fixing hook 119, and the cover structure 11 does not have a slot 113, and both sides of the flexible structure 13 extend to the outside of the side blocking structure 15. The fixing block 116 cooperates with the fixing groove 122 so that the connection between the covering structure 11 and the bearing structure 12 is limited in the horizontal direction after the covering is closed, and the whole is more stable. When in use, the locking effect is not easily affected by external factors such as vibration.

[0069] In this embodiment, refer to Fig.12 Since the shielding edge 112 is arranged at the edge of the top plate 111, and both sides of the flexible structure 13 extend to the outside of the side blocking structure 15, the side blocking structure 15 is actually located within the projection range of the top plate 111 when the cover is closed. Fig.13 As shown, when the covering structure 11 is covered, the fixing hook 119, the hook 14 and the side blocking structure 15 are all located in the shielding area of ​​the top plate 111 and the flexible structure 13, and the shielding edge 112, the top plate 111 and the flexible structure 13 surround the light guide column 3, reducing the light-transmitting gap and better shielding the light. At the same time, since the top plate 111 of the covering structure 11 does not have a card slot 113 in this embodiment, it can further prevent light from leaking out.

[0070] In this embodiment, if Figure 11-Figure 14 As shown, the fixing hook 119 is disposed on the inner side of the top plate 111 of the covering structure 11 and can be buckled with the hook 14. Fig.11 , Fig.14 , the number and position of the fixing hooks 119 correspond to the number and position of the hooks 14. According to the actual situation, the fixing hooks 119 can be arranged inside the two hooks 14 to cooperate with the hooks 14. For example, when there are two hooks 14 and their hook-shaped parts are arranged oppositely, there are also two fixing hooks 119, and the hook-shaped parts of the fixing hooks 119 are arranged in opposite directions. That is to say, for a set of hooks 14 and fixing hooks 119, their hook-shaped parts are arranged in opposite directions.

[0071] When the cover is closed, the fixing hook 119 is buckled on the inner side of the hook 14. Fig.11 , Fig.14 As shown. The fixing hook 119 is elastic, and its top surface has an inclined guide surface. After covering, for each group of hooks 14 and fixing hooks 119, their guide surfaces are basically parallel. When the covering structure 11 and the bearing structure 12 are covered, the fixing hook 119 first contacts the hook 14, and sliding occurs between their guide surfaces, and they push each other so that the fixing hook 119 and the hook 14 are bent toward the side away from their hook-shaped parts. In other words, for a group of hooks 14 and fixing hooks 119, the hook 14 bends toward the outside, and the fixing hook 119 bends toward the inside. As the covering structure 11 moves further downward, the bottom surface of the hook-shaped part of the hook 14 is higher than the top surface of the hook-shaped part of the fixing hook 119. At this time, the hook 14 and the fixing hook 119 are no longer pushed by each other, and rebound and complete the buckling, so as to achieve the locking of the covering structure 11 and the bearing structure 12, so that the shading device 1 can be opened and locked without the need for multiple parts to cooperate, and is easy to install and applicable to a wide range of scenarios.

[0072] In this embodiment, the fixing blocks 116 are formed by extending from both ends of the shielding edge 112 and are respectively located on both sides of the top plate 111. Figure 11-Figure 14 As shown. The position of the fixing groove 122 corresponds to the position of the fixing block 116, and is opened on both sides of the bearing structure 12. According to the actual situation, since the two sides of the flexible structure 13 extend to the outside of the side blocking structure 15, and the side blocking structure 15 is located within the projection range of the top plate 111 when the cover is closed, the edge of the bearing structure 12 actually extends to be close to the outermost edge of the flexible structure 13. In other words, the fixing groove 122 is opened on the outside of the side blocking structure 15, and when the cover is closed, the fixing block 116 is also located on the outside of the side blocking structure. After the cover is closed, when there are factors such as shaking that interfere with the installation stability of the shading device 1, in the horizontal direction, the fixing block 116 is restricted in the fixing groove 122, so that the connection between the covering structure 11 and the bearing structure 12 is limited in the horizontal direction, and the whole is more stable, avoiding external factors such as vibration from affecting the locking effect. At the same time, the fixing block 116 extends on the shielding edge 112, and can cooperate with the shielding edge 112 to further improve the effect of side shading of the light guide column 3.

[0073] The shading device in this embodiment limits the light guide column by the covering structure and the bearing structure, wherein the positioning part and its positioning groove limit the light guide column in the horizontal direction, and the first fixing part and the second fixing part limit the light guide column in the vertical direction. At the same time, the covering structure, the bearing structure cooperate with the side block structure and the flexible structure, and when covering, the fixed hook and the hook are correspondingly engaged, so that the covering structure and the bearing structure can achieve simple and effective cooperation, further realize the locking of the shading device, and enable the shading device to adapt to a variety of installation scenarios and requirements, and do not require a variety of parts to cooperate, easy to install, and widely applicable scenarios. At the same time, setting the fixed hook, the hook and the side block structure within the covering range of the top plate, the flexible structure and the shielding edge can also further improve the shading effect. The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
