[0043] 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 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 allow a section of the light guide column 3 to extend to the light-transmitting hole of the shell, so that light can be emitted from the light-transmitting hole of the shell to serve 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 installation order can be adjusted according to actual conditions. During actual installation, according to the product structure and needs, the light guide column 3 can be placed first, and then the shading device 1 can be installed on its outside, and then covered to block light; or the shading device 1 can be positioned first to open it, and then the light guide column 3 is placed in the shading device 1, and then the shading device 1 is closed to block light.

[0044] 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 a variety of installation scenarios and needs, and does not require the coordination of multiple parts. It is easy to install and has a wide range of applicable scenarios.

[0045] Example 1:

[0046] Reference Figure 1-Figure 2 The shading device 1 includes a supporting structure 12, a covering structure 11 and a hook 14. The supporting structure 12 is used to accommodate the light guide column 3. The covering structure 11 and the supporting structure 12 are connected by a flexible structure 13 and rotated to open and close, surrounding the light guide column 3 to achieve the function of shielding light. The covering structure 11 and the supporting 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 light out. In this embodiment, the light hole 131 is formed on one side of the flexible structure 13 and is arranged in the same shape as the light guide column 3. There are two hooks 14, which are arranged on the supporting structure 12 and extend toward the covering structure 11. 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 supporting 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. It is easy to install and has a wide range of applicable scenarios.

[0047] In this embodiment, the light guide column 3 is placed in a horizontal direction, and the corresponding housing 4 is provided with a horizontal light-transmitting hole. Figure 1 The covering 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 covering 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 tilted. For example, the top plate 111 can be set to be tilted along the direction of light propagation to adapt to the shape of the housing 4 and other external structures, such as Figure 10 As shown. The shielding edge 112 protrudes from the edge of the top plate 111. When the supporting structure 12 and the covering structure 11 are covered, the shielding edge 112 shields the light-emitting element 21 and the light guide column 3. In other words, the shielding edge 112 is used to shield the side of the light guide column 3. The light-emitting element 21 is located on the side of the light guide column 3 away from the light hole 131. When the covering structure 11 and the supporting structure 12 are covered, the portion of the shielding edge 112 along the light propagation direction can accommodate the light-emitting element 21 within the space formed by the covering structure 11 and the supporting structure 12, thereby achieving further light shielding.

[0048] Reference Figure 1-Figure 3, the top plate 111 is provided with slots 113 on both sides perpendicular to the direction of light propagation, and the hook 14 passes through the slots 113 and engages with the top surface of the top plate 111. The shielding edges 112 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 Figure 10 As 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 supporting 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 engagement, thereby locking the covering structure 11 and the supporting structure 12. This allows the shading device 1 to 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.

[0049] 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 supporting structure 12 and perpendicular to the supporting 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 supporting structure 12 are covered. It 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 supporting 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.

[0050] In this embodiment, if Figure 1-Figure 2As shown, the supporting structure 12 is provided with two symmetrically arranged positioning portions 16. Positioning slots 161 are defined on opposing sides of the two positioning portions 16. The light guide 3 is positioned between the two positioning portions 16, which provide horizontal positioning for the light guide 3. In this embodiment, the horizontally positioned light guide 3 has protruding positioning posts 31 on either side, perpendicular to the direction of light propagation. The light-emitting element 21 emits light horizontally toward one side of the light guide 3. When the light guide 3 is placed between the two positioning portions 16, the two positioning posts 31 engage in the two positioning slots 161, achieving positioning.

[0051] Reference Figure 1-Figure 2 A first fixing portion 171 is raised on the covering structure 11, and at least one second fixing portion 172 is raised on the supporting 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 supporting 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 can be opened on the supporting 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 supporting structure 12, thereby increasing the stability of the device.

[0052] The shading device 1 in this embodiment limits the position of the light guide column 3 via the covering structure 11 and the supporting structure 12. Specifically, the positioning portion 16 and its positioning groove 161 limit the light guide column 3 in the horizontal direction, while the first fixing portion 171 and the second fixing portion 172 limit the light guide column 3 in the vertical direction. Simultaneously, the covering structure 11 and the supporting structure 12 cooperate with the side blocking structure 15 and the flexible structure 13 to achieve multi-directional blocking of the light guide column 3. The hook 14 engages with the top plate 111 to further lock the shading device 1, making it adaptable to a variety of installation scenarios and requirements without requiring multiple parts, making it easy to install and applicable to a wide range of scenarios.

[0053] Example 2:

[0054] Reference Figure 4The shading device 1 includes a supporting structure 12, a covering structure 11, and a hook 14, wherein the supporting structure 12 and the covering structure 11 are connected via a flexible structure 13. The supporting structure 12, the covering structure 11, and the flexible structure 13 of this embodiment are basically the same as the supporting structure 12, the covering structure 11, and the flexible structure 13 of the first embodiment. The light guide column 3 is a light guide column 3 placed in the horizontal direction, which will not be described in detail in this embodiment. The only difference between this embodiment and the first embodiment is 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 of the covering structure 11 to the side blocking structure 15.

[0055] In this embodiment, if Figure 4-Figure 6 As 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 supporting structure 12, the side block structure 15 enters the projection area of ​​the top plate 111. That is to say, when the covering structure 11 is covered with the supporting 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 mechanism 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 provided 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 light.

[0056] 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 direction of light transmission, 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 supporting 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 supporting structure 12, thereby increasing the stability of the device.

[0057] The shading device in this embodiment limits the position of the light guide column through the covering structure and the supporting structure, wherein the positioning portion and its positioning groove limit the light guide column in the horizontal direction, and the first fixing portion and the second fixing portion limit the light guide column in the vertical direction. At the same time, the covering structure, the supporting structure cooperate with the side block structure and the flexible structure, and when covering, the top of the side block structure enters the first avoidance groove, reducing the gap between it and the covering structure, effectively achieving the blocking of the light guide column in multiple directions. The hook and the top plate are engaged and cooperated to further achieve the locking of the shading device, so that the shading device can adapt to a variety of installation scenarios and needs, and does not require the coordination of multiple parts. It is easy to install and has a wide range of applicable scenarios.

[0058] Example 3:

[0059] Reference Figure 7-Figure 9 The shading device 1 of the embodiment of the present application includes a supporting structure 12, a covering structure 11 and a hook 14. Among them, the supporting structure 12 is used to accommodate the light guide column 3, and the covering structure 11 and the supporting structure 12 are connected by a flexible structure 13 and rotated to open and close, thereby surrounding the light guide column 3 and achieving the function of shielding the light. The covering structure 11 and the supporting 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 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 upward. The light hole 131 is formed by the side of the covering structure 11 and the supporting 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 supporting 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 supporting structure 12, or on two sides of the supporting structure 12 that are perpendicular to each other. The hook 14 is elastic, and the covering structure 11 and the supporting 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.

[0060] In this embodiment, the light-transmitting hole on the housing 4 is a vertical light-transmitting hole, which is arranged 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.

[0061] Reference Figure 7-Figure 8A block 114 protrudes from the shielding edge 112, and the hook 14 engages with the block 114. The length of the inner surface of the hook 14 extending from the support structure 12 is substantially the same as the distance between the top surface of the block 114 and the support structure 12. This allows the top surface of the block 114 to contact the inner surface of the hook 14 when the covering structure 11 is covered with the support structure 12. This means that the hook 14 can ensure that the shading device 1 has a good shading effect. The top surface of the hook 14 has an inclined guide surface on the side facing the inner side of the support structure 12. When the covering structure 11 is covered with the support structure 12, the shielding edge 112 first contacts the hook 14, causing 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.

[0062] In this embodiment, referring to Figure 7-Figure 9 , a first accommodating groove 123 and a limiting card 124 are provided on the supporting structure 12, and a second accommodating groove 117 and a second avoidance groove 118 are provided on the covering structure 11. The first accommodating groove 123 cooperates with the second accommodating 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 raised on its side, and according to actual conditions, its bottom can have a raised shape of a square or other shape. A positioning blind hole 121 is provided in the first accommodating groove 123. 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 set in the positioning blind hole 121.

[0063] Reference Figure 7-Figure 8 The position-limiting clip 124 cooperates with the positioning blind hole 121 to jointly limit the position of the light guide column 3. Depending on the actual situation, the position-limiting clip 124 can be made into a buckle shape, and its curved portion limits the bottom of the light guide column 3. Since the light guide column 3 is placed vertically in this embodiment, the position-limiting clip 124 cooperates with the positioning blind hole 121 to better fix the light guide column 3. At the same time, since the position-limiting clip 124 protrudes from the supporting structure 12, a second avoidance groove 118 is also provided on the covering structure 11 at a position corresponding to the position-limiting clip 124 to avoid and accommodate the position-limiting clip 124.

[0064] In this embodiment, referring to Figure 7-Figure 8 A fixing block 116 is raised 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 the covering is completed.

[0065] The shading device in this embodiment utilizes a covering structure and a supporting structure to limit the position of the light guide column. The first and second receiving slots cooperate to accommodate the light guide column, while the positioning blind holes and limiting clamps limit the light guide column. The covering and supporting structures work together to effectively block the light guide column in multiple directions. The hook and the clamping block engage to further lock the shading device, making it adaptable to various installation scenarios and requirements without requiring multiple parts, making it easy to install and widely applicable.

[0067] Reference Figure 11 、 Figure 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, 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 opened 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 slot 113 is not provided on the covering structure 11, 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 supporting structure 12 is limited in the horizontal direction after the covering is closed, making the whole more stable and not easily affected by external factors such as vibration during use.

[0068] In this embodiment, referring to Figure 12 Since the shielding edge 112 is set at the edge of the top plate 111, and the two 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. Figure 13 As shown, when the cover structure 11 is completely closed, the fixing hook 119, the hook 14, and the side blocking structure 15 are all located within the shielding area of ​​the top plate 111 and the flexible structure 13. The shielding edge 112, the top plate 111, and the flexible structure 13 surround the light guide column 3, reducing the light transmission gap and better blocking the light. At the same time, because the top plate 111 of the cover structure 11 does not have a locking groove 113 in this embodiment, it can further prevent light from leaking out.

[0069] In this embodiment, if Figure 11-14 As shown, the fixing hook 119 is provided on the inner side of the top plate 111 of the covering structure 11 and can be engaged with the hook 14. Figure 11 、 Figure 14 The number and position of the fixing hooks 119 correspond to the number and position of the hooks 14. Depending on the actual situation, the fixing hooks 119 can be positioned inside the two hooks 14 to mate with them. For example, if there are two hooks 14 and their hook-shaped portions are positioned opposite each other, two fixing hooks 119 can also be provided, with their hook-shaped portions facing in opposite directions. In other words, for a set of hooks 14 and fixing hooks 119, their hook-shaped portions face each other.

[0070] When the cover is closed, the fixing hook 119 is buckled on the inner side of the hook 14. Figure 11 、 Figure 14 As shown. The fixing hook 119 is elastic and has an inclined guide surface on its top surface. After closing, for each set of hooks 14 and fixing hooks 119, their guide surfaces are substantially parallel. When the covering structure 11 and the supporting structure 12 are closed, the fixing hook 119 first contacts the hook 14, causing sliding between their guide surfaces and pushing each other so that both the fixing hook 119 and the hook 14 bend toward the side away from their hook-shaped portions. In other words, for a set of hooks 14 and fixing hooks 119, the hook 14 bends outward and the fixing hook 119 bends inward. As the covering structure 11 moves further downward, the bottom surface of the hook-shaped portion of the hook 14 is higher than the top surface of the hook-shaped portion of the fixing hook 119. At this time, the hook 14 and the fixing hook 119 are no longer pushed by each other, rebound and complete the engagement, achieving the locking of the covering structure 11 and the supporting structure 12. This allows the shading device 1 to be opened and locked without the need for multiple parts to cooperate, making it easy to install and applicable to a wide range of scenarios.

[0071] 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 11-14 As shown. The position of the fixing groove 122 corresponds to the position of the fixing block 116, and is provided on both sides of the supporting structure 12. According to actual conditions, since both sides of the flexible structure 13 extend to the outside of the side block structure 15, and the side block structure 15 is located within the projection range of the top plate 111 when the cover is closed, the edge of the supporting structure 12 actually extends to be close to the outermost edge of the flexible structure 13. In other words, the fixing groove 122 is provided on the outside of the side block structure 15, and when the cover is closed, the fixing block 116 is also located on the outside of the side block structure. After the cover is closed, when factors such as shaking that interfere with the installation stability of the shading device 1 occur, the fixing block 116 is horizontally confined within the fixing groove 122, so that the connection between the covering structure 11 and the supporting structure 12 is horizontally limited, making the whole more stable and preventing 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 side shading effect of the light guide column 3.

[0072] The shading device in this embodiment limits the position of the light guide column by the covering structure and the supporting structure, wherein the positioning portion and its positioning groove limit the light guide column in the horizontal direction, and the first fixing portion and the second fixing portion limit the light guide column in the vertical direction. At the same time, the covering structure, the supporting structure cooperate with the side block structure and the flexible structure, and when covering, the fixing hook and the hook are correspondingly engaged, so that the covering structure and the supporting structure can achieve simple and effective cooperation, further realizing the locking of the shading device, and making the shading device adaptable to a variety of installation scenarios and requirements, without the need for multiple parts to cooperate, easy to install and applicable to a wide range of scenarios. At the same time, arranging the fixing 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 can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
