Description

Technical Field

[0001] This invention relates to the field of server technology, and more specifically to light-emitting modules and electronic devices. Background Technology

[0002] Servers and other electronic devices typically include a power button and an illumination module. The power button usually has a power icon that illuminates to indicate the power-on status of the server or other electronic device. The illumination module is typically used to display other operating statuses of the server or other electronic device. The illumination module usually includes status indicator lights (LEDs) and light guides. The status indicator lights are arranged on the PCB (printed circuit board), and the light guides project the illumination status of the status indicator lights on the PCB onto the surface of the server.

[0003] However, since both the status indicator light and the power button need to be connected to the PCB, and the light guide column occupies a large space; and due to the size of electronic devices such as servers and the layout limitations of the area where the power button is located, the light-emitting module and the power button need to be set at a certain distance, which occupies a lot of space. Summary of the Invention

[0004] In view of this, the present invention provides a light-emitting module and an electronic device to solve the problem that the light-emitting module and the power button occupy too much space.

[0005] In a first aspect, the present invention provides a light-emitting module adapted to be connected to an electronic device, the electronic device including a housing and a power button and a circuit board disposed inside the housing, the housing having an opening, one end of the power button being connected to the circuit board, and the other end being disposed at the opening; the light-emitting module including a light-emitting element and a light-guiding element; the light-emitting element being connected inside the housing, adapted to be sleeved on the outer periphery of the power button, and adapted to be connected to the circuit board; one end of the light-guiding element being connected to one side of the light-emitting element, and the other end being disposed at the opening; and the light-guiding element being adapted to be sleeved on the outer periphery of the power button.

[0006] Beneficial Effects: The power button can display the power-on status of servers and other electronic devices. In this invention, through connection with the circuit board, the light-emitting element can smoothly emit light at the appropriate time to display other operating states of servers and other electronic devices; the light guide is set between the opening and the light-emitting element, allowing the light emitted by the light-emitting element to be smoothly guided out of the housing through the opening, making it easy for maintenance personnel and users outside the housing to see. In this invention, both the light-emitting element and the light guide of the light-emitting module are suitable for being fitted around the outer periphery of the power button, ensuring the normal light emission and light guiding of the light-emitting module to display other operating states; it also makes reasonable use of the surrounding area of ​​the power button, saving the space occupied by the light-emitting module and the power button as a whole; and it unifies the layout of the light-emitting module and the power button, allowing it to be used as a whole on servers and other electronic devices of different specifications and layouts, eliminating the need to develop multiple circuit boards, indicator lights, and light guide structures to adapt to different electronic devices, thus reducing development costs.

[0007] In one alternative embodiment, the light-emitting module further includes a mounting base, which is fixedly connected to the housing, and the other side of the light-emitting element is connected to the mounting base.

[0008] Beneficial effects: The mounting base allows for a more stable and secure connection of the light-emitting element to the housing without requiring any modifications to the light-emitting element itself.

[0009] In one optional embodiment, the fixing base includes a first annular body and a connecting plate; the first annular body is adapted to be sleeved on the outer periphery of the power button and connected to the other side of the light-emitting element; the connecting plate protrudes from the outer periphery of the first annular body and is adapted to be fixedly connected to the housing by fasteners.

[0010] Beneficial effects: The first annular body is sleeved on the outer periphery of the power button, which can increase the connection area between the fixing base and the light-emitting element, making the connection more stable, and can also guide the connection process of the fixing base, simplifying the connection of the fixing base; the setting of the connecting plate can not only enhance the strength of the first annular body, but also facilitate the connection of the first annular body to the shell, providing positional compensation for the connection between the first annular body and the shell.

[0011] In one optional embodiment, the connecting plate is provided with a first mounting hole and at least one positioning hole, the housing is adapted to be provided with a second mounting hole and at least one positioning post, the positioning post is adapted to be disposed in the positioning hole, and the fastener is adapted to connect the first mounting hole and the second mounting hole in sequence.

[0012] Beneficial effects: The first and second mounting holes facilitate the detachable connection of fasteners between the mounting base and the housing. The positioning holes and positioning pins allow for pre-positioning of the mounting base's connecting plate at installation, preventing mistaken connections and facilitating the connection between the mounting base's connecting plate and the housing.

[0013] In one optional embodiment, the light-emitting element includes a flexible adapter and a light-emitting part; one end of the flexible adapter is provided with an adapter ring, and the other end is adapted to be bent and connected to a connector on the circuit board; the adapter ring is connected between the light guide and the fixing base, and the adapter ring is sleeved on the outer periphery of the power button; the light-emitting part is connected to the adapter ring and disposed between the adapter ring and the light guide.

[0014] Beneficial effects: One end of the flexible adapter has an adapter ring, one side of which connects to the light guide and the other side to the mounting base. The adapter ring also connects the light-emitting part to the side close to the light guide, facilitating the extraction of light emitted from the light-emitting part. The flexible connector is easy to bend and deform as needed, and it also allows for conductive connection between the light-emitting part and the connector on the circuit board. Compared with light guide pillars in related technologies, the flexible adapter can be sheet-like, occupying less space. Furthermore, due to the flexibility of the flexible adapter, the light-emitting part can be positioned close to the opening to minimize the light guide path of the light guide and ensure better light guiding effect.

[0015] In one alternative embodiment, the flexible adapter is a flexible circuit board.

[0016] Beneficial effects: Flexible circuit boards are easy to fold and bend, and can also connect the light-emitting part to the circuit board.

[0017] In one alternative implementation, the light-emitting part is a light-emitting diode.

[0018] In one alternative embodiment, the light-emitting portion has a plurality of light-emitting portions, which are distributed circumferentially around the adapter ring.

[0019] Beneficial effect: It can form a ring of light around the power button, which is more aesthetically pleasing and eye-catching, making it easier for users and maintenance personnel to notice.

[0020] In one alternative embodiment, one side of the adapter ring is bonded and fixed to the light guide by an adhesive.

[0021] Beneficial effects: During bonding, the mating surface between the adapter ring and the light guide is relatively large, resulting in a more stable connection that is less prone to damage. In a specific implementation, the adhesive can be a hot melt adhesive.

[0022] In one alternative embodiment, the other side of the adapter ring is bonded to the mounting base with an adhesive.

[0023] Beneficial effects: During bonding, the mating surface between the adapter ring and the fixing base is relatively large, resulting in a more stable connection that is less prone to damage. In a specific implementation, the adhesive can be a hot melt adhesive.

[0024] In one optional embodiment, the light guide includes a second annular body and a first limiting flange; the second annular body is adapted to be sleeved on the outer periphery of the power button and slides in cooperation with the outer periphery of the power button, and one end is disposed at the opening; the first limiting flange protrudes from the outer periphery of the second annular body and is disposed near the other end of the second annular body, and one side of the first limiting flange is adapted to abut against the inner wall of the housing at the opening; the other end of the second annular body and / or the other side of the first limiting flange is connected to one side of the light-emitting element.

[0025] Beneficial effects: The first limiting flange can abut against the inner wall of the housing to limit the light-emitting module within the housing. The second annular body can both guide the light from the light-emitting element to the outside of the housing and slide with the power button to prevent the gap between the power button and the second annular body from being too large, which would cause light to leak out from the gap between the power button and the second annular body, thus preventing the leaked light from affecting the light-emitting effect of the light-emitting module and preventing light leakage between the light-emitting module and the power button.

[0026] In one optional embodiment, the light guide is made of a light-transmitting material, and the outer surface of the light guide includes a light-transmitting area and a non-light-transmitting area. The end face of the light guide facing the light-emitting element and the end face away from the light-emitting element are both light-transmitting areas, and the outer ring surface and the inner ring surface of the light guide are both non-light-transmitting areas.

[0027] Beneficial effects: The light-transmitting areas are located on the end face of the light guide facing the light-emitting element and the end face away from the light-emitting element, allowing light to propagate in a straight line, resulting in a short propagation path and minimal loss during propagation. The non-transmitting areas are located on the outer and inner ring surfaces of the light guide, meaning the light guide is positioned on the outer ring relative to the inner ring, or the exposed portion is the outer ring surface, preventing light from passing through and reducing light loss. The inner ring surface is also a non-transmitting area, preventing light leakage between the power button and the second ring body, reducing light loss, and also preventing light crosstalk between the light-emitting module and the power button.

[0028] In one alternative embodiment, the mounting base is made of an opaque material.

[0029] Beneficial effects: It can prevent the light emitted by the light-emitting component from leaking out of the mounting base, thus ensuring the light guiding effect of the light guide component.

[0030] In one alternative embodiment, the end of the light guide away from the light-emitting element is disposed at the opening and is adapted to protrude through the opening from the outer surface of the housing and the power button.

[0031] Beneficial effects: The light guide protrudes from the outer surface of the housing and the outer surface of the power button. When maintenance personnel are maintaining servers and other electronic equipment with power on, the protruding light guide surrounding the power button can protect the power button and prevent accidental touches that could shut down the server or other electronic equipment.

[0032] In one optional embodiment, the light guide has a first annular end face and a second annular end face arranged in a stepped pattern on the end face facing the light-emitting element. The first annular end face is coaxially disposed on the inner circumference of the second annular end face and protrudes from the second annular end face. An annular receiving groove is provided on the second annular end face, and the light-emitting part is disposed in the annular receiving groove. The flexible adapter is sleeved on the outer circumference of the convex ring where the first annular end face is located, and one side of the flexible adapter is connected to the second annular end face, and the other side is connected to the fixed base. The power button includes a base and a pressing part. The base is fixedly connected to the circuit board, and the pressing part is movably connected to the end of the base facing away from the circuit board. The end of the pressing part away from the base is a movable end, which is movably disposed at the opening. The end of the movable end near the base protrudes outward with a second limiting flange, which is movably disposed between the first annular end face and the base. The outer diameter of the second limiting flange is larger than the outer diameter of the first annular end face and smaller than the diameter of the inner ring of the fixed base.

[0033] Beneficial effects: The second annular end face is provided with an annular receiving groove to accommodate the light-emitting part, preventing it from being damaged by the light guide and the fixing seat. It also collects the light emitted by the light-emitting part, ensuring that most of the light passes through the light-transmitting area away from the light-emitting part. The light guide is made of a light-transmitting material, and its outer surface includes light-transmitting and non-light-transmitting areas. Both the end face of the light guide facing the light-emitting part and the end face away from the light-emitting part are light-transmitting areas, while the outer and inner annular surfaces are non-light-transmitting areas. Furthermore, the fixing seat is made of a non-light-transmitting material, which further ensures that the light emitted by the light-emitting part can only be guided out through the light guide via the annular receiving groove. The first annular end face protrudes from the second annular end face, allowing for the positioning of the flexible adapter part fitted around the outer circumference of the protruding ring where the first annular end face is located, facilitating the connection of the flexible adapter part. The power button's base and pressing part are movable. When the pressing part is pressed into contact with the base, the power button is activated, powering on or off the server or other electronic equipment. The pressing part is provided with a second limiting flange, which can limit the position of the pressing part and prevent the pressing part from detaching from the inner ring of the light-emitting element under the elastic force of the elastic element, or from getting stuck with the inner ring of the light-emitting element and unable to move. Preferably, there is a gap between the second limiting part and the first annular end face to prevent the pressing part from hitting the light-emitting element with great force under the elastic force of the elastic element, which would cause damage to the light-emitting element and the light guide.

[0034] Secondly, the present invention also provides an electronic device, including a housing, a circuit board, a power button, and the aforementioned light-emitting module; the housing has an opening; the circuit board is disposed within the housing; one end of the power button is connected to the circuit board, and the other end is disposed at the opening; the light-emitting module includes a light-emitting element and a light-guiding element; the light-emitting element is connected within the housing, adapted to be sleeved around the outer periphery of the power button, and adapted to be connected to the circuit board; one end of the light-guiding element is connected to one side of the light-emitting element, and the other end is disposed at the opening; and the light-guiding element is adapted to be sleeved around the outer periphery of the power button.

[0035] In one alternative implementation, the electronic device is a server, and the housing is the housing of the server's mounting ears. Attached Figure Description

[0052] According to an embodiment of the present invention, in one aspect, a light-emitting module 100 is provided, such as... Figures 1 to 6As shown, the light-emitting module 100 is adapted to be connected to an electronic device. The electronic device includes a housing 200 and a power button 300 and a circuit board 400 disposed inside the housing 200. The housing 200 has an opening 201. One end of the power button 300 is connected to the circuit board 400, and the other end is disposed at the opening 201. The light-emitting module 100 includes a light-emitting element 1 and a light guide element 2. The light-emitting element 1 is connected inside the housing 200, adapted to be fitted around the outer periphery of the power button 300, and adapted to be connected to the circuit board 400. One end of the light guide element 2 is connected to one side of the light-emitting element 1, and the other end is disposed at the opening 201. The light guide element 2 is adapted to be fitted around the outer periphery of the power button 300.

[0053] The power button 300 can display the power-on status of electronic devices such as servers. In this embodiment, through connection with the circuit board 400, the light-emitting element 1 can smoothly emit light at appropriate times to display other operating states of the electronic devices such as servers; the light guide 2 is disposed between the opening 201 and the light-emitting element 1, which can smoothly guide the light emitted by the light-emitting element 1 through the opening 201 out of the housing 200, so that it can be noticed by maintenance personnel and users outside the housing 200. In this embodiment, the light-emitting element 1 and the light guide 2 of the light-emitting module 100 are both suitable for being fitted around the outer periphery of the power button 300, which not only ensures the normal light emission and light guiding of the light-emitting module 100 to display other operating states, but also makes reasonable use of the surrounding area of ​​the power button 300, saving the space occupied by the light-emitting module 100 and the power button 300 as a whole; and the layout of the light-emitting module 100 and the power button 300 is unified, so that it can be used as a whole on electronic devices such as servers with different specifications and layouts, without the need to develop multiple circuit boards 400, indicator lights and light guide structures to adapt to different electronic devices, thus reducing development costs.

[0054] In one embodiment, the light-emitting module 100 further includes a fixing base 3, which is fixedly connected inside the housing 200, and the other side of the light-emitting element 1 is connected to the fixing base 3.

[0055] The mounting base 3 allows for a more stable connection of the light-emitting element 1 to the housing 200 without requiring any modification to the light-emitting element 1 itself.

[0056] In one embodiment, such as Figure 4 and Figure 6 As shown, the fixing base 3 includes a first annular body 31 and a connecting plate 32; the first annular body 31 is adapted to be sleeved on the outer periphery of the power button 300 and connected to the other side of the light-emitting element 1; the connecting plate 32 protrudes from the outer periphery of the first annular body 31 and is adapted to be fixedly connected to the housing 200 by fasteners 33.

[0057] The first annular body 31 is sleeved on the outer periphery of the power button 300, which can increase the connection area between the fixing base 3 and the light-emitting element 1, making the connection more stable, and can also guide the connection process of the fixing base 3, simplifying the connection of the fixing base 3; the setting of the connecting plate 32 can enhance the strength of the first annular body 31 and facilitate the connection of the first annular body 31 to the housing 200, providing positional compensation for the connection between the first annular body 31 and the housing 200.

[0058] In a specific implementation, the fastener 33 may be a fastening structure such as a screw or bolt, and the connecting plate 32 may be detachably connected to the housing 200 through the fastener 33.

[0059] As an alternative implementation, the fixing base 3 may include a horizontal bar and vertical bars connected to both ends of the horizontal bar. The horizontal bar is fixedly connected to the housing 200, and the two vertical bars are respectively connected to the two ends of the other side of the light-emitting element 1.

[0060] In one embodiment, the connecting plate 32 is provided with a first mounting hole 34 and at least one positioning hole 35, the housing 200 is adapted to be provided with a second mounting hole and at least one positioning post 203, the positioning post 203 is adapted to be disposed in the positioning hole 35, and the fastener 33 is adapted to connect the first mounting hole 34 and the second mounting hole in sequence.

[0061] The first mounting hole 34 and the second mounting hole facilitate the detachable connection of the fastener 33 to the fixing base 3 and the housing 200. The positioning hole 35 and the positioning post 203 allow for pre-positioning of the connecting plate 32 of the fixing base 3 at the installation point, achieving a foolproof effect and facilitating the connection between the connecting plate 32 of the fixing base 3 and the housing 200. In a specific embodiment, the fastener 33 can be a screw or bolt, and the connecting plate 32 can be detachably connected to the housing 200 through the fastener 33. Correspondingly, the first mounting hole 34 and the second mounting hole are threaded holes, or the first mounting hole 34 is a normal through hole and the second mounting hole is a threaded hole.

[0062] like Figure 7 and Figure 9 As shown, a mounting post protrudes from the inner wall of the housing 200, and the second mounting hole is a blind hole provided on the mounting post; the positioning post 203 protrudes from the side of the mounting post and is connected to the mounting post, and the end face of the positioning post 203 away from the inner wall of the housing 200 protrudes from the end face of the mounting post, and the fixing seat 3 abuts against the end face of the mounting post away from the inner wall of the housing 200.

[0063] The second mounting hole is designed as a blind hole to prevent the fastener 33 from protruding from the outer surface of the housing 200 after being connected to the first mounting hole 34 and the second mounting hole in sequence, thus ensuring the integrity and aesthetics of the outer surface of the housing 200. The mounting post and positioning post 203 compensate for the distance between the fixing seat 3 and the housing 200, allowing the connecting plate 32 to abut against the end face of the mounting post away from the inner wall of the housing 200, increasing the contact area, ensuring connection stability, and preventing the connecting plate 32 from deflecting or tilting. Furthermore, the end face of the positioning post 203 away from the inner wall of the housing 200 protrudes from the end face of the mounting post, ensuring that the end of the positioning post 203 extends into the positioning hole 35 for positioning and limiting. The connection between the positioning post 203 and the mounting post also enhances the strength of the mounting post and the positioning post 203. In a preferred embodiment, two positioning posts 203 can be provided, respectively located on both sides of the mounting post; correspondingly, two positioning holes 35 are also provided, respectively located on both sides of the first mounting hole 34. There is no need to impose too much limit on the number of positioning holes 35 and positioning pins 203; the number of the two should correspond one-to-one.

[0064] In a specific implementation, both the mounting post and the positioning post 203 are set on the front panel of the housing 200 with the opening 201, so that the light-emitting module 100 can be placed in a more forward position.

[0065] In one embodiment, the light-emitting element 1 includes a flexible adapter 11 and a light-emitting part 12; one end of the flexible adapter 11 is provided with an adapter ring 111, and the other end is adapted to be bent and connected to the connector 401 on the circuit board 400; the adapter ring 111 is connected between the light guide 2 and the fixing base 3, and the adapter ring 111 is sleeved on the outer periphery of the power button 300; the light-emitting part 12 is connected to the adapter ring 111 and disposed between the adapter ring 111 and the light guide 2.

[0066] One end of the flexible adapter 11 is provided with an adapter ring 111. One side of the adapter ring 111 is connected to the light guide 2, and the other side is connected to the fixing base 3. The adapter ring 111 also connects the light-emitting part 12 to the side close to the light guide 2, so as to guide the light emitted by the light-emitting part 12 out. The flexible connection part is easy to bend to deform as needed, and can also conduct the light-emitting part 12 to the connector 401 of the circuit board 400. Compared with the light guide column in the related technology, the flexible adapter 11 can be thin and takes up less space. Moreover, due to the flexibility of the flexible adapter 11, the light-emitting part 1 can be placed near the opening 201 to shorten the light guide path of the light guide 2 as much as possible and ensure better light guiding effect.

[0067] In a specific implementation, the flexible connection part has a thin sheet structure, which saves a lot of space.

[0068] In one embodiment, the flexible adapter 11 is a flexible circuit board 400. The flexible circuit board 400, also known as an FPC connector 401, is a PCB connector 401 made of soft material (a material that can be folded and bent), and is commonly used for connecting LCD displays to driving circuits (PCBs).

[0069] In one embodiment, the light-emitting part 12 is a light-emitting diode (LED). The flexible circuit board 400 can be easily folded and bent, and can also connect the light-emitting part 12 to the circuit board 400. A light-emitting diode, or LED for short, is a commonly used light-emitting device that emits light by releasing energy through the recombination of electrons and holes; it is widely used in the lighting field.

[0070] In one embodiment, there are multiple light-emitting parts 12, which are distributed circumferentially around the adapter ring 111. This forms a ring-shaped light-emitting circle around the power button 300, which is more aesthetically pleasing, more eye-catching, and easier for users and maintenance personnel to notice.

[0071] In a preferred embodiment, there are multiple light-emitting parts 12, which are evenly distributed around the circumference of the transition ring 111. This forms a more uniform light strip, which is more aesthetically pleasing.

[0072] In one embodiment, one side of the adapter ring 111 is bonded and fixed to the light guide 2 by an adhesive.

[0073] During bonding, the mating surface between the adapter ring 111 and the light guide 2 is relatively large, resulting in a more stable connection that is less prone to damage. In a specific embodiment, the adhesive can be a hot melt adhesive.

[0074] In one implementation, the other side of the adapter ring 111 is bonded and fixed to the fixing seat 3 by an adhesive.

[0075] During bonding, the mating surface between the adapter ring 111 and the fixing base 3 is relatively large, resulting in a more stable connection that is less prone to damage. In a specific embodiment, the adhesive can be a hot melt adhesive.

[0076] In one embodiment, the light guide 2 includes a second annular body 21 and a first limiting flange 22; the second annular body 21 is adapted to be sleeved on the outer periphery of the power button 300 and slides in cooperation with the outer periphery of the power button 300, and one end is disposed at the opening 201; the first limiting flange 22 protrudes from the outer periphery of the second annular body 21 and is disposed near the other end of the second annular body 21, and one side of the first limiting flange 22 is adapted to abut against the inner wall of the housing 200 at the opening 201; the other end of the second annular body 21 and / or the other side of the first limiting flange 22 is connected to one side of the light-emitting element 1.

[0077] The first limiting flange 22 can abut against the inner wall of the housing 200 to limit the light-emitting module 100 within the housing 200. The second annular body 21 can both guide the light from the light-emitting element 1 to the outside of the housing 200 and slide with the power button 300 to prevent the gap between the power button 300 and the second annular body 21 from being too large, causing light to leak out from the gap between the power button 300 and the second annular body 21, thus preventing the leaked light from affecting the light-emitting effect of the light-emitting module 100.

[0078] In one embodiment, the light guide 2 is made of a light-transmitting material, and the outer surface of the light guide 2 includes a light-transmitting area 23 and a non-light-transmitting area 24. The end face of the light guide 2 facing the light-emitting element 1 and the end face away from the light-emitting element 1 are both light-transmitting areas 23, and the outer ring surface and the inner ring surface of the light guide 2 are both non-light-transmitting areas 24.

[0079] The light-transmitting area 23 is located on the end face of the light guide 2 facing the light-emitting element 1 and the end face away from the light-emitting element 1, allowing light to propagate in a straight line with a short propagation path and minimal loss during propagation. The non-light-transmitting area 24 is located on the outer and inner ring surfaces of the light guide 2, meaning that the light guide 2 is positioned on the outer ring relative to the inner ring, or the exposed portion is the outer ring surface, preventing light from passing through and reducing light loss. The inner ring surface is also a non-light-transmitting area 24, which prevents light from leaking between the power button 300 and the second annular body 21, further reducing light loss.

[0080] In a specific implementation, a non-light-guiding black paint can first be sprayed onto the outer surface of the light guide 2. This outer surface excludes the end face of the light guide 2 facing the light-emitting element 1, but includes the inner ring surface of the light guide 2. Then, the black paint on the end face of the light guide 2 facing away from the light-emitting element 1 is removed, including by laser engraving. After removing the black paint from the end face of the light guide 2 facing away from the light-emitting element 1, a translucent paint can be sprayed onto it to increase light transmission.

[0081] In one embodiment, the mounting base 3 is made of an opaque material. This prevents light emitted by the light-emitting element 1 from leaking out of the mounting base 3, ensuring the light-guiding effect of the light guide element 2.

[0082] In one embodiment, the end of the light guide 2 away from the light-emitting element 1 is disposed at the opening 201, and is adapted to protrude through the opening 201 from the outer surface of the housing 200 and the power button 300.

[0083] The light guide 2 protrudes from the outer surface of the housing 200 and the outer surface of the power button 300. When maintenance personnel maintain servers and other electronic equipment while they are powered on, the light guide 2 protrudes around the power button 300, which can protect the power button 300 and prevent accidental touches that could cause the server or other electronic equipment to shut down.

[0084] In a specific implementation, the end of the light guide 2 facing away from the light-emitting element 1 is a rounded transition end. The protruding rounded transition end has no sharp edges, so that maintenance personnel and operators will not be scratched when they touch or brush against it, thus protecting the fingers of maintenance personnel and operators.

[0085] In one embodiment, the light guide 2 has a first annular end face 25 and a second annular end face 26 arranged in a stepped pattern on one end face facing the light-emitting element 1. The first annular end face 25 is coaxially disposed on the inner circumference of the second annular end face 26, and the first annular end face 25 protrudes from the second annular end face 26. The second annular end face 26 has an annular receiving groove 27, and the light-emitting part 12 is disposed in the annular receiving groove 27. The flexible adapter part 11 is sleeved on the outer circumference of the convex ring where the first annular end face 25 is located, and one side of the flexible adapter part 11 is connected to the second annular end face 26, and the other side is connected to the fixing base 3. The power button 3 The device 300 includes a base 301 and a pressing part 302. The base 301 is fixedly connected to the circuit board 400. The pressing part 302 is movably connected to one end of the base 301 facing away from the circuit board 400. The end of the pressing part 302 away from the base 301 is a movable end. The movable end is movably disposed at the opening 201. A second limiting flange 303 protrudes outward from the end of the movable end near the base 301. The second limiting flange 303 is movably disposed between the first annular end face 25 and the base 301. The outer diameter of the second limiting flange 303 is larger than the outer diameter of the first annular end face 25 and smaller than the diameter of the inner ring of the fixed base 3.

[0086] The second annular end face 26 is provided with an annular receiving groove 27, which can accommodate the light-emitting part 12, prevent the light-emitting part 12 from being squeezed and damaged by the light guide 2 and the fixing seat 3, and also collect the light emitted by the light-emitting part 12, ensuring that most of the light from the light-emitting part 12 is transmitted through the light-transmitting area 23 away from the light-emitting part 12. The light guide 2 is made of light-transmitting material, and the outer surface of the light guide 2 includes a light-transmitting area 23 and a non-light-transmitting area 24. The end face of the light guide 2 facing the light-emitting part 1 and the end face away from the light-emitting part 1 are both light-transmitting areas 23, and the outer annular surface and the inner annular surface of the light guide 2 are both non-light-transmitting areas 24. The fixing seat 3 is made of non-light-transmitting material, which can further ensure that the light emitted by the light-emitting part 12 can only be discharged from the light guide 2 through the annular receiving groove 27. The first annular end face 25 protrudes from the second annular end face 26, which can position the flexible transition part 11 sleeved on the outer periphery of the protruding ring where the first annular end face 25 is located, which facilitates the connection of the flexible transition part 11. The power button 300 has a base 301 and a pressing part 302 that are movably configured. When the pressing part 302 is pressed until it contacts the base 301, the power button 300 is activated, powering on or off electronic devices such as servers. The pressing part 302 is provided with a second limiting flange 303, which limits the position of the pressing part 302, preventing it from detaching from the inner ring of the light-emitting element 1 under the elastic force of the elastic member, or from becoming stuck and unable to move. Preferably, there is a gap between the second limiting part and the first annular end face 25 to prevent the pressing part 302 from forcefully impacting the light-emitting element 1 under the elastic force of the elastic member, thus preventing damage to the light-emitting element 1 and the light guide element 2.

[0087] According to an embodiment of the present invention, another aspect provides an electronic device, including a housing 200, a circuit board 400, a power button 300, and the aforementioned light-emitting module 100; the housing 200 has an opening 201; the circuit board 400 is disposed within the housing 200; one end of the power button 300 is connected to the circuit board 400, and the other end is disposed at the opening 201; the light-emitting module 100 includes a light-emitting element 1 and a light guide element 2; the light-emitting element 1 is connected within the housing 200, adapted to be sleeved on the outer periphery of the power button 300, and adapted to be connected to the circuit board 400; one end of the light guide element 2 is connected to one side of the light-emitting element 1, and the other end is disposed at the opening 201; and the light guide element 2 is adapted to be sleeved on the outer periphery of the power button 300.

[0088] The power button 300 can display the power-on status of electronic devices such as servers. In this embodiment, through connection with the circuit board 400, the light-emitting element 1 can smoothly emit light at appropriate times to display other operating states of the electronic devices such as servers; the light guide 2 is disposed between the opening 201 and the light-emitting element 1, which can smoothly guide the light emitted by the light-emitting element 1 through the opening 201 out of the housing 200, so that it can be noticed by maintenance personnel and users outside the housing 200. In this embodiment, the light-emitting element 1 and the light guide 2 of the light-emitting module 100 are both suitable for being fitted around the outer periphery of the power button 300, which not only ensures the normal light emission and light guiding of the light-emitting module 100 to display other operating states, but also makes reasonable use of the surrounding area of ​​the power button 300, saving the space occupied by the light-emitting module 100 and the power button 300 as a whole; and the layout of the light-emitting module 100 and the power button 300 is unified, so that it can be used as a whole on electronic devices such as servers with different specifications and layouts, without the need to develop multiple circuit boards 400, indicator lights and light guide structures to adapt to different electronic devices, thus reducing development costs. Furthermore, the light-emitting module 100 provided in this embodiment is connected to the power button 300, which also enhances the product's technological feel.
