[0035] In some embodiments, the button module further includes a second circuit board on which a connector assembly is disposed, and a portion of the first circuit board is connected to the connector assembly to supply power to a plurality of second light-emitting elements.

[0036] In some embodiments, the connector assembly is provided with a slot, into which a portion of the second circuit board is inserted for connection with the connector assembly.

[0037] Secondly, in some embodiments, a box ear structure is provided, the box ear structure including a box ear shell and a button module of any one of the first aspects above, the button module being mounted on the box ear shell.

[0038] Thirdly, in some embodiments a server is provided, the server including a server chassis and a housing structure of any one of the second aspects above;

[0039] The ear-shaped housing is connected to the server chassis.

[0040] In some embodiments, a controller is provided in the server chassis. The controller is electrically connected to the light-emitting module of the button module. The controller is used to obtain the operating status of the server and control the light-emitting module to emit light according to the operating status.

[0041] In some embodiments, since the light guide assembly has a receiving cavity, the push-button component passes through the light guide assembly and abuts against the power supply assembly. At least a portion of the light-emitting module is located in the receiving cavity, so the light emitted by the light-emitting module can illuminate the light guide assembly. Since the power supply assembly includes a pressable portion, a first light-emitting portion, and a power connector, the first light-emitting portion is connected to the power connector. The pressable portion has a light-transmitting hole, and the first light-emitting portion faces the light-transmitting hole. Therefore, the light emitted by the first light-emitting portion can illuminate the light-transmitting hole. Since the push-button component abuts against the pressable portion and is light-guiding, and the push-button component at least covers a portion of the light-transmitting hole, when the push-button component is pressed, the push-button component can press the pressable portion, thereby applying force to the power connector. After receiving the force, the power connector can perform the corresponding operation. Since the first light-emitting part indicates the server's power-on status and the light-emitting module indicates the server's operating status, when the button module is installed on the ear structure and the ear structure is connected to the server, the operator can press the push-button component. The push-button component applies force to the pressable part, which in turn applies force to the power connector, allowing the power connector to power the server. During this process, the first light-emitting part will produce different colors depending on the server's power-on status. The light emitted by the first light-emitting part will illuminate the push-button component, allowing the operator to see the light from the first light-emitting part through the button cap, thus knowing the server's power-on status. The light-emitting module will also emit light, which will illuminate the light guide component, allowing the operator to see the light from the light-emitting module through the light guide component, thus knowing the server's operating status. In some embodiments, by providing a first light-emitting part in the power connector of the button module, and providing a light guide component and a light-emitting module, it is equivalent to integrating the light-emitting module and the light guide component. Thus, the button module not only has button functions, but also indicates the power-on status or running status of the service, thereby diversifying the functions of the button module and making it easier for operators to know the status of the server.

[0068] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0069] As shown in Figures 1 to 21, the button module is applied to the ear structure of the server. The button module includes: a pressing component 10, a power supply component 20, a light-emitting module 30, and a light guide component 40.

[0070] The light guide assembly 40 has a receiving cavity, in which at least a portion of the light-emitting module 30 is located. The push assembly 10 passes through the light guide assembly 30 and abuts against the power assembly 20. The light-emitting module 30 is used to indicate the operating status of the server. The power assembly 20 includes a pressable part 21, a first light-emitting part 22, and a power connector 23. The pressable part 21 is provided with a light-transmitting hole 211, and the light from the first light-emitting part 22 passes through the light-transmitting hole 211 and through the push assembly 10. When the push assembly 10 is pressed, the push assembly 10 presses the pressable part 21, the first light-emitting part 22 emits light to indicate the power-on status of the server, and the light-emitting module 30 emits light to indicate the operating status of the server.

[0071] In some embodiments, the light guide component 40 may have a through hole, through which the push-button component 10 can pass. The power supply component 20 is located outside the receiving cavity, allowing the push-button component 10 to pass through the light guide component 40 and abut against it. Furthermore, when the power supply component 20 includes a pressable portion 21, a first light-emitting portion 22, and a power connector 23, the first light-emitting portion 22 is connected to the power connector 23, the pressable portion 21 is connected to the power connector 23, the push-button component 10 abuts against the pressable portion 21, and the push-button component 10 guides light. The first light-emitting portion 22 faces the light-transmitting hole 211, and the push-button component 10 at least covers a portion of the light-transmitting hole 211. The first light-emitting portion 22 indicates the power-on status of the server. Additionally, the first light-emitting portion 22 can emit light of different colors, and the light-emitting module 30 can also emit light of different colors.

[0072] In some embodiments, since the light guide assembly 40 has a receiving cavity, the push assembly 10 passes through the light guide assembly 40 and abuts against the power assembly 20, and at least a portion of the light-emitting module 30 is located in the receiving cavity, the light emitted by the light-emitting module 30 can illuminate the light guide assembly 40. Since the power assembly 20 includes a pressable part 21, a first light-emitting part 22, and a power connector 23, the first light-emitting part 22 is connected to the power connector 23, and the pressable part 21 is provided with a light-transmitting hole 211, and the first light-emitting part 22 faces the light-transmitting hole 211, the light emitted by the first light-emitting part 22 can illuminate the light-transmitting hole 211 and pass through the hole 211. Since the push assembly 10 abuts against the pressable part 21 and the push assembly 10 can guide light, and the push assembly 10 covers at least part of the light-transmitting hole 211, when the push assembly 10 is pressed, the push assembly 10 can press the pressable part 21, thereby the pressable part 21 applies force to the power connector 23, and the power connector 23 can perform the corresponding operation after receiving the force. Since the first light-emitting part 22 indicates the power-on status of the server and the light-emitting module 30 indicates the operating status of the server, when the button module is installed on the ear structure and the ear structure is connected to the server, the operator can press the push component 10, which will apply force to the pressable part 21. The pressable part 21 will then apply force to the power connector 23, which will then power the server. During this process, the first light-emitting part 22 will also produce different colors depending on the power-on status of the server. The light emitted by the first light-emitting part 22 will shine on the push component 10, so the operator can see the light of the first light-emitting part 22 through the button cap and know the power-on status of the server. The light-emitting module 30 will also emit light, and the light of the light-emitting module 30 will shine on the light guide component 40, so the operator can also see the light of the light-emitting module 30 through the light guide component 40 and know the operating status of the server. In some embodiments, by providing a first light-emitting part 22 in the power connector 23 of the button module, and providing a light guide component 40 and a light-emitting module 30, it is equivalent to integrating the light-emitting module 30 and the light guide component 40. Thus, the button module not only has button functions, but also indicates the power-on status or running status of the service, thereby diversifying the functions of the button module and making it easier for operators to know the status of the server.

[0073] In some embodiments, the power-on state of the server may include the server being powered on and running, the server being powered off, and the server being powered on and in standby mode; the operating state of the server may include the server operating under low load, the server operating under medium load, and the server operating under high load.

[0074] In addition, the button module can be applied to the cabinet structure of a 1U server. Since the 1U server is small in size, the cabinet structure is also small in size. The button component 10, power component 20, light-emitting module 30 and light guide component 40 are integrated, which makes the button module highly integrated, resulting in a small button module size. The button module also has diversified functions, thus providing a button module with the characteristics of small size and diversified functions, which is more suitable for the cabinet structure of a 1U server.

[0075] In some embodiments, the first light-emitting part 22 can emit light of different colors, and each color of light corresponds to a power-on state of the server. For example, the first light-emitting part 22 can emit red, blue, and green light. Red corresponds to the server being powered on and running, blue corresponds to the server being powered off, and green corresponds to the server being powered on and in standby mode. Thus, the operator can quickly know the power-on state of the server by observing the color of the first light-emitting part 22 emitted by the pressing component 10.

[0076] In some embodiments, the light-emitting module 30 can emit light of different colors, with each color corresponding to a server's operating state. For example, the light-emitting module 30 can emit purple, cyan, and brown light, with purple corresponding to low server load, cyan to medium load, and brown to high load. Thus, operators can quickly determine the server's operating state by observing the color of the light-emitting module 30 transmitted by the light guide component 40.

[0077] The server can be equipped with a controller that can detect the server's power-on and operational status. After applying the button module to the ear-shaped structure, the ear-shaped structure can be installed on the server, and the power connector 23 and the light-emitting module 30 can be electrically connected to the controller. During use, after the controller detects the server's operational status, it can control the light-emitting module 30 to emit different colors of light. Similarly, after detecting the server's power-on status, the controller can control the first light-emitting part 22 to emit different colors of light. The controller can integrate a central processing unit (CPU) or a control chip. The CPU or control chip controls the first light-emitting part 22 and the light-emitting module 30 to emit different colors of light.

[0078] In some embodiments, the first light-emitting part 22 can be a light-emitting diode (LED). Of course, the first light-emitting part 22 can also be other light-emitting components, such as a light bulb. The type of the first light-emitting part 22 is not limited.

[0079] In some embodiments, the light-emitting module 30 may include a light-emitting diode (LED). Of course, the light-emitting module 30 may also include other light-emitting components, such as a light bulb. This is not a limitation.

[0080] In some embodiments, the actuating component 10 abuts against the pressable portion 21, so that after pressing the actuating component 10, the actuating component 10 can compress the pressable portion 21, applying force to the pressable portion 21, thereby subjecting the power connector 23 to force, and the power connector 23 can then power on the server. After the pressing component 10 is released, the pressable portion 21 returns to its initial state, thereby causing the actuating component 10 to reset. After pressing the actuating component 10 again, the actuating component 10 presses the pressable portion 21 again, thereby subjecting the power connector to force, and the power connector 23 can then power off the server. The pressable portion 21 is elastic.

[0081] In some embodiments, the pressing component 10 may include a button lever 11 and a button head 12. One end of the button lever 11 is connected to the button head 12, and the other end of the button lever 11 abuts against or is connected to the pressable part 21. The button lever 11 covers at least part of the light-transmitting hole 211. The button module also includes an elastic element 50, which is sleeved on the button lever 11. The two opposite ends of the elastic element 50 abut against the button head 12 and the pressable part 21, respectively. Both the button head 12 and the button lever 11 can guide light.

[0082] Since one end of the button lever 11 is connected to the button head 12, and the other end of the button lever 11 abuts against or connects to the pressable part 21, and the button lever 11 covers at least part of the light-transmitting hole 211, once the first light-emitting part 22 emits light, the light emitted by the first light-emitting part 22 can be transmitted to the light-transmitting hole 211 and illuminate the button lever 11. Since both the button head 12 and the button lever 11 can guide light, after the light from the first light-emitting part 22 illuminates the button lever 11, the light can pass through the button lever 11 and be transmitted to the button head 12, thereby allowing the button head 12 to transmit the light to the outside so that the operator can see it. Since the elastic element 50 is sleeved on the button lever 11, and the two opposite ends of the elastic element 50 abut against the button head 12 and the pressable part 21 respectively, when the pressing assembly 10 is pressed, the button head 12 is actually pressed. The button head 12 can drive the button lever 11 to move, and the button lever 11 presses the pressable part 21. During this process, the button head 12 will also press the elastic element 50, so that both the pressable part 21 and the elastic element 50 are compressed. Once the pressing of the button head 12 is stopped, the pressable part 21 will cause the button head 12 to drive the button lever 11 to return to its original position due to its own elasticity. At the same time, the elastic element 50 will also exert force on the button head 12 due to its own elasticity, so that the button head 12 will drive the button lever 11 to return to its original position. By setting up a button head 12 and a button lever 11, and by sleeved the elastic element 50 on the button lever 11, the button head 12 can be subjected to the force of the pressable part 21 and the force of the elastic element 50 when it returns to the initial position, thereby ensuring that the button head 12 can quickly return to the initial position.

[0083] In some embodiments, the elastic element 50 can be a spring. Of course, the elastic element 50 can also be a resilient plastic column with a through hole so that the button rod 11 can pass through the through hole. The type of elastic element 50 is not limited.

[0084] In some embodiments, the actuating assembly 10 may further include a pusher 60, which is connected to one end of the button lever 11. The pusher 60 abuts against the pressable portion 21 and covers the light-transmitting hole 211. The two ends of the elastic member 50 abut against the pusher 60 and the button head 12, respectively. The pusher 60 is light-guiding. The size of the pusher 60 may be larger than the size of the button lever 11.

[0085] Since one end of the button lever 11 is connected to a pusher 60, which abuts against the pressable portion 21, and both ends of the elastic member 50 abut against the pusher 60 and the button head 12 respectively, when the button head 12 is pressed, the button head 12 applies force to the button lever 11, which in turn applies force to the pusher 60, causing the pusher 60 to apply force to the pressable portion 21. Because the size of the pusher 60 is larger than that of the button lever 11, the contact area between the pusher 60 and the pressable portion 21 is larger. Therefore, when the pressable portion 21 is pressed, although the pusher 60 is subjected to force from the pressable portion 21, the actual pressure on the pusher 60 is smaller, resulting in a smaller pressure transmitted to the button lever 11 and extending the service life of the button lever 11. Since the pusher 60 is a light guide, the light emitted by the first light-emitting part 22, after shining on the light-transmitting hole 211, can be transmitted to the pusher 60. The light then passes through the pusher 60 and shines on the button lever 11, finally transmitting the light from the button head 12 to the outside, allowing the operator to see the light emitted by the first light-emitting part 22. By setting the pusher 60, the pressure on the button lever 11 can be reduced without affecting the transmission of light from the first light-emitting part 22, thereby helping to extend the service life of the button lever 11.

[0086] It should be noted that the dimension of the button lever 11 refers to the dimension of its cross-section, which is the surface perpendicular to the axial direction of the button lever 11. The dimension of the pusher 60 refers to its circumferential dimension. Therefore, having a dimension smaller than that of the pusher 60 ensures that the projection of the button lever 11 in a preset direction lies within the projection of the pusher 60 in the preset direction, which is either the direction from the button lever 11 to the pusher 60, or the direction from the pusher 60 to the button lever 11.

[0087] In addition, in some embodiments, the surface of the push member 60 facing the button rod 11 is provided with a connecting groove 601; one end of the button rod 11 is connected to the connecting groove 601.

[0088] Since the pusher 60 has a connecting groove 601 on its surface facing the button lever 11, when it is necessary to connect the button lever 11 to the pusher 60, one end of the button lever 11 can be connected to the connecting groove 601, thus directly connecting the pusher 60 and the button lever 11. In other words, by providing the connecting groove 601 on the pusher 60, it is convenient to connect the button lever 11 to the pusher 60.

[0089] Of course, the button lever 11 can also be connected to the pusher 60 by setting a groove at one end of the button lever 11 and a boss on the pusher 60, with the boss embedded in the groove, so that the button lever 11 is connected to the pusher 60.

[0090] In some embodiments, the button lever 11 can also be directly embedded in the light-transmitting hole 211, thereby connecting the button lever 11 to the pressable part 21. In this case, when the button head 12 is pressed, the button head 12 presses the button lever 11, and the button lever 11 can apply force to the pressable part 21. The button lever 11 can be interference-fitted with the light-transmitting hole 211.

[0091] Of course, the end of the button lever 11 can also abut against the pressable part 21, so that the button lever 11 completely covers the light-transmitting hole 211. This is not a limitation.

[0092] In addition, in some embodiments, a slot 111 is provided on the outer wall of the button rod 11 along the circumferential direction of the button rod 11, one end of the button rod 11 is embedded in the connecting groove 601, and the slot 111 is located in the connecting groove 601; a plurality of elastic buckles 602 are provided at intervals on the groove wall of the connecting groove 601 along the circumferential direction of the button rod 11, and the elastic buckles 602 are engaged with the slot 111 so that one end of the button rod 11 is connected to the connecting groove 601.

[0093] Since a slot 111 is provided on the outer wall of the button rod 11 along the circumferential direction of the button rod 11, and one end of the button rod 11 is embedded in the connecting groove 601, and multiple elastic buckles 602 are provided at intervals on the groove wall of the connecting groove 601 along the circumferential direction of the button rod 11, when it is necessary to connect the button rod 11 to the push member 60, one end of the connecting rod can be directly embedded in the connecting groove 601 on the push member 60. In this process, the end of the connecting rod will squeeze the elastic buckle 602, causing the elastic buckle 602 to contract. Once the slot 111 on the button rod 11 enters the connecting groove 601, and the slot 111 moves to the position of the elastic buckle 602, the elastic buckle 602 will stop being subjected to force, and the elastic buckle 602 will extend and embed into the slot 111, so that one end of the button rod 11 is fixed by the elastic buckle 602, and the button rod 11 is connected to the connecting groove 601. When it is necessary to separate the button lever 11 from the connecting groove 601, force can be applied to the button lever 11, causing the elastic buckle 602 to separate from the slot 111, and the button lever 11 can then be removed from the connecting groove 601. By providing the slot 111 on the button lever 11 and the elastic buckle 602 in the connecting groove 601, it is easy to connect or separate the button lever 11 from the connecting groove 601.

[0094] The number of elastic clips 602 can be set according to actual needs. For example, the number of elastic clips 602 can be 5, or the number of elastic clips 602 can be 3. There is no limit to the number of elastic clips 602.

[0095] In addition, in some embodiments, the surface of the button head 12 facing away from the button lever 11 has a first light-emitting area 121, and a first light-shielding layer is provided on the part of the button head 12 other than the first light-emitting area 121. A first light-shielding layer is also provided on the side wall of the button lever 11.

[0096] With this configuration, once the first light-emitting part 22 emits light, after the light reaches the button lever 11, it can continue to reach the button head 12. The first light-emitting area 121 on the button head 12 can then transmit the light from the first light-emitting part 22 to the outside. However, other parts of the button head 12 and the first light-shielding layer on the side wall of the button lever 11 can block the light from the first light-emitting part 22 from reaching other locations, thus preventing light leakage. By providing a first light-shielding layer on the button head 12 and the side wall of the button lever 11, light leakage is avoided while ensuring that the light from the first light-emitting part 22 can be seen by the operator.

[0097] In some embodiments, the shape of the first light-emitting area 121 can be set according to actual needs. For example, the first light-emitting area 121 is annular, or for another example, the first light-emitting area 121 is square. There is no limitation thereto.

[0098] In addition, in some embodiments, the aesthetics of the button head 12 when transmitting light from the first light-emitting part 22 can be improved by setting the shape of the first light-emitting area 121.

[0099] In some embodiments, the light guide assembly 40 includes a light guide element 41 and a light guide base 42. The light guide element 41 is provided with a receiving cavity. The light guide element 41 and the light guide base 42 are spaced apart. At least a portion of the light-emitting modules 30 are located between the light guide element 41 and the light guide base 42, and at least a portion of the light-emitting modules 30 extend into the receiving cavity. The light guide element 41 and the light guide base 42 are connected through the light-emitting modules 30.

[0100] Since the light guide 41 and the light guide base 42 are spaced apart, and at least part of the light-emitting module 30 is located between the light guide 41 and the light guide base 42, the light guide 41 and the light guide base 42 can be connected through the light-emitting module 30, thereby ensuring that the components of the light guide assembly 40 are not easily separated.

[0101] In addition, in some embodiments, the light-emitting module 30 includes a first circuit board 31 and a second light-emitting element 32 disposed on the first circuit board 31; a light guide 41 and a light guide base 42 are spaced apart, the first circuit board 31 is located in the gap between the light guide 41 and the light guide base 42, and the light guide 41 and the light guide base 42 are connected through the first circuit board 31. A receiving groove 412 is provided on the side of the light guide 41 facing the light guide base 42, and a first through hole 411 penetrates the bottom of the receiving groove 412. A plurality of second light-emitting elements 32 are located in the receiving groove 412, and the receiving groove 412 forms a receiving cavity. The light guide 41 may have a first through hole 411, the light guide base 42 may have a second through hole 421, and the first circuit board 31 may have a third through hole 311. The first through hole 411, the second through hole 421, and the third through hole 311 are positioned opposite each other. A portion of the push-button component 10 passes through the first through hole 411, the second through hole 421, and the third through hole 311 and abuts against the pushable part 21. The first through hole 411 and the second through hole 421 form a through hole. The first through hole penetrates the bottom of the receiving groove.

[0102] Since the light guide 41 and the light guide base 42 are spaced apart, the first circuit board 31 can be placed in the gap between the light guide 41 and the light guide base 42, and the light guide 41 and the light guide base 42 are connected through the first circuit board 31. Since the light guide 41 is provided with a first through hole 411, the light guide base 42 is provided with a second through hole 421, and the first circuit board 31 is provided with a third through hole 311, the first through hole 411, the second through hole 421 and the third through hole 311 are positioned opposite each other, when the pressing component 10 is set, a part of the pressing component 10 can pass through the first through hole 411, the second through hole 421 and the third through hole 311 and abut against the pressable part 21, thereby equivalent to the first through hole 411 and the second through hole 421 forming a through hole on the light guide component 40. Since the light guide 41 has a receiving groove 412 on the side facing the light guide base 42, and the first through hole 411 penetrates the bottom of the receiving groove 412, and multiple second light-emitting elements 32 are located in the receiving groove 412, when the multiple second light-emitting elements 32 emit light, the light from the second light-emitting elements 32 can be transmitted to the light guide 41. The light guide 41 can then transmit the light emitted by the second light-emitting elements 32 to the outside of the button module, making it visible to the operator. By setting up the light guide 41 and the light guide base 42, and by setting the receiving groove 412 on the light guide 41, the placement of the first circuit board 31 can be facilitated, and the light emitted by the multiple second light-emitting elements 32 can be easily seen by the operator.

[0103] It should be noted that the first circuit board 31 can be a flexible printed circuit (FPC), or it can be a printed circuit board (PCB). There is no limitation on the type of the first circuit board 31.

[0104] In some embodiments, the second light-emitting element 32 can be a light-emitting diode (LED). Of course, the second light-emitting element 32 can also be other light-emitting components, such as a light bulb. The type of the second light-emitting element 32 is not limited.

[0105] In some embodiments, the first circuit board 31 has a first surface and a second surface opposite to each other along its thickness direction; the first surface faces the light guide 41, the second surface faces the light guide base 42, the second light-emitting element 32 is disposed on the first surface, the light guide 41 is connected to the first surface, and the light guide base 42 is connected to the second surface. Both the first and second surfaces may be provided with adhesive; the light guide 41 is bonded to the first surface by adhesive, and the light guide base 42 is bonded to the second surface by adhesive.

[0106] Since the first surface faces the light guide 41 and the second surface faces the light guide base 42, and multiple second light-emitting elements 32 are disposed on the first surface, when the multiple second light-emitting elements 32 emit light, the light can be transmitted to the light guide 41, allowing the light guide 41 to transmit the light to the outside of the button module to ensure that the operator can see it. Because both the first and second surfaces are provided with adhesive, after placing the first circuit board 31 between the light guide 41 and the light guide base 42, the light guide 41 can be bonded to the first surface with adhesive, and the light guide base 42 can be bonded to the second surface with adhesive, thus facilitating the connection between the light guide base 42 and the light guide 41. By providing adhesive on the first and second surfaces, the connection between the light guide base 42 and the light guide 41 can be easily achieved.

[0107] It should be noted that when applying adhesive to the first surface, the adhesive on the first surface should avoid the second light-emitting element 32 to prevent the second light-emitting element 32 from being bonded by the adhesive.

[0108] In some embodiments, multiple second light-emitting elements 32 surround the third through hole 311 and are spaced apart along the circumferential direction of the third through hole 311. With this arrangement, when the multiple second light-emitting elements 32 emit light, the light from them can surround the button lever 11 and illuminate the light guide 41, resulting in a ring-shaped distribution of light at the point of transmission of light through the light guide 41. This avoids excessive light from the second light-emitting elements 32 being transmitted to the button lever 11 and ultimately to the button head 12, preventing the light on the button head 12 from becoming mixed and affecting the operator's viewing experience. By setting multiple second light-emitting elements 32 spaced apart around the third through hole 311, the operator can easily view the light emitted by the second light-emitting elements 32.

[0109] In some embodiments, a plurality of second light-emitting elements 32 may be equally spaced around the third through hole 311, that is, the distance between any two adjacent second light-emitting elements 32 is equal along the circumferential direction of the third through hole 311. Of course, a plurality of second light-emitting elements 32 may also be spaced around the third through hole 311, but the distance between two adjacent second light-emitting elements 32 may not be equal. This is not a limitation.

[0110] In addition, in some embodiments, the surface of the light guide 41 facing away from the light guide base 42 may be provided with a relief groove 413. Along the direction from the light guide 41 to the light guide base 42, the relief groove 413 is positioned opposite to the receiving groove 412. The first through hole 411 passes through the bottom of both the receiving groove 412 and the relief groove 413. At least part of the pressing component 10 passes through the first through hole 411, and the other part of the pressing component 10 is located in the relief groove 413.

[0111] Since the surface of the light guide 41 facing away from the light guide base 42 can be provided with a relief groove 413, and the first through hole 411 passes through both the receiving groove 412 and the bottom of the relief groove 413, when installing the push assembly 10, the push assembly 10 can be directly passed through the first through hole 411. Thus, some keycaps pass through the first through hole 411, while other keys are located in the relief groove 413. This ensures that a significant portion of the light emitted by the second light-emitting element 32 is transmitted to the relief groove 413 on the light guide 41, and then to the surface of the light guide 41 facing away from the base, thereby preventing excessive light from the second light-emitting element 32 from being transmitted to the button head 12. By providing a relief groove 413 on the surface of the light guide 41 facing away from the light guide base 42, it is beneficial to separate the light from the first light-emitting part 22 and the second light-emitting element 32. This allows operators to observe the light from the first light-emitting part 22 and the second light-emitting element 32 through the button head 12 and the light guide 41 respectively, thus understanding the different states of the server.

[0112] In some embodiments, when the pressing component 10 includes a button head 12 and a button lever 11, the button lever 11 may pass through a first through hole 411, and the pressing component 10 is located in the clearance.

[0113] In some embodiments, the light guide base 42 is detachably connected to the power connector 23 in the power supply assembly 20, allowing the light guide base 42 and the power connector 23 to be separated or connected. This arrangement allows for direct connection of the light guide base 42 and the power supply assembly 20 when needed, and also facilitates separation when necessary.

[0114] In some embodiments, the power connector 23 is provided with a first snap-fit ​​groove 231, and the light guide base 42 is provided with a first snap-fit ​​buckle 422. The first snap-fit ​​buckle 422 is snapped into the first snap-fit ​​groove 231 so that the light guide base 42 and the power assembly 20 can be detachably connected; or, the light guide base 42 is provided with a second snap-fit ​​groove, and the power connector 23 is provided with a second snap-fit ​​buckle. The second snap-fit ​​buckle is snapped into the second snap-fit ​​groove so that the light guide base 42 and the power assembly 20 can be detachably connected.

[0115] When the power connector 23 has a first latching slot 231 and the light guide base 42 has a first latching buckle 422, when it is necessary to connect the light guide base 42 to the power connector 23, the light guide base 42 can be directly moved to the power connector 23, and the first latching buckle 422 can be engaged in the first latching slot 231, thereby completing the connection between the power connector 23 and the light guide base 42. Furthermore, the light guide base 42 can be fixed by the power connector 23, preventing potential shaking of the light guide base 42.

[0116] It should be noted that the number of first card clips 422 and the number of first card slots 231 can be set according to actual needs. For example, the number of first card clips 422 and the number of first card slots 231 can both be 2. Or, for example, the number of first card clips 422 and the number of first card slots 231 can both be 4. There is no limitation on this.

[0117] When the light guide base 42 is provided with a second latching slot and the power connector 23 is provided with a second latching buckle, when it is necessary to connect the light guide base 42 and the power connector 23, the light guide base 42 can be directly moved to the power connector 23, and the second latching buckle can be engaged in the second latching slot, thereby completing the connection between the power connector 23 and the light guide base 42. Furthermore, the light guide base 42 can be fixed by the power connector 23, preventing potential shaking of the light guide base 42.

[0118] It should be noted that the number of second card clips and the number of second card slots can be set according to actual needs. For example, the number of second card clips and the number of second card slots can both be 2. Or, for example, the number of second card clips and the number of second card slots can both be 4. There is no limitation on this.

[0119] In some embodiments, the first circuit board 31 may include a setting part 312 and a connecting part 313. The setting part 312 is connected to the connecting part 313. The setting part 312 is located between the light guide 41 and the light guide base 42, and a third through hole 311 is provided on the setting part 312. A plurality of second light-emitting elements 32 are disposed on the setting part 312. The connecting part 313 is used to connect a power supply connector to supply power to the plurality of second light-emitting elements 32.

[0120] Since the setting part 312 is located between the light guide member 41 and the light guide base 42, multiple second light-emitting elements 32 can be mounted on the setting part 312, allowing the light emitted by the multiple second light-emitting elements 32 to be transmitted to the light guide member 41. The setting part 312 is connected to the connecting part 313, thus allowing the power supply connector to be connected via the connecting part 313. The power supply connector can then transmit electrical energy to the setting part 312 via the connecting part 313, and subsequently to the multiple second light-emitting elements 32, supplying power to the multiple second light-emitting elements 32 so that they can emit light. In other words, by setting the first circuit board 31 as the setting part 312 and the connecting part 313, it is convenient to supply power to the multiple second light-emitting elements 32 in practical applications.

[0121] It should be noted that adhesive can be applied to the two opposite surfaces of the setting part 312, so that the light guide base 42 and the light guide 41 are respectively bonded to the two opposite surfaces of the setting part 312, thereby connecting the light guide 41 and the light guide base 42.

[0122] In some embodiments, one end of the connecting portion 313 is connected to the setting portion 312, and the other end of the connecting portion 313 is used to connect to the power supply connector. The middle part of the connecting portion 313 is bent, and the middle part of the connecting portion 313 is the portion between the two ends of the connecting portion 313.

[0123] With this design, when the button module is applied to the earpiece structure, the bend in the connecting part 313 ensures that the connecting part 313 can avoid other components in the earpiece structure, facilitating the connection of the connecting part 313 to other components. In other words, by setting the middle bend of the connecting part 313, it is easy to install the button module in the earpiece.

[0124] In addition, in some embodiments, the surface of the light guide 41 facing away from the light guide base 42 has a second light-emitting area 414, and a second light-shielding layer is provided on the surface of the light guide 41 facing away from the light guide base, except for the second light-emitting area 414. A second light-shielding layer is also provided on the sidewall of the light guide 41 and the sidewall of the light guide base 42.

[0125] With this configuration, once the second light-emitting element 32 emits light, the light can be transmitted to the light guide 41. The presence of the second light-shielding layer ensures that the light from the second light-emitting element 32 is only transmitted to the second light-emitting area 414, preventing the light from being transmitted to other locations and causing light leakage. By setting the second light-shielding layer, it is ensured that the light from the second light-emitting element 32 is only transmitted to the second light-emitting area 414, preventing the light from being transmitted to other locations through the sidewall of the light guide 41, thereby avoiding light leakage problems when the button module is actually used.

[0126] It should be noted that the thickness of the second light-shielding layer can be set according to actual needs. For example, the thickness of the second light-shielding layer is 3 mm, or for another example, the thickness of the second light-shielding layer is 5 mm. There is no limitation on this.

[0127] In addition, in some embodiments, the button module may also include a second circuit board 70, on which a connector assembly 80 is disposed, and a portion of the first circuit board 31 is connected to the connector assembly 80 to supply power to a plurality of second light-emitting elements 32.

[0128] With this configuration, in practical applications, the second circuit board 70 can be directly connected to the power supply, or the second circuit board 70 can be electrically connected to the controller in the server. This allows electrical energy to be transferred to the second circuit board 70 and then to the first circuit board 31, enabling the multiple second light-emitting elements 32 to emit light. In other words, by setting up the second circuit board 70, it is convenient to supply power to the second light-emitting elements 32.

[0129] It should be noted that connector assembly 80 can be a power supply connector.

[0130] In some embodiments, the connector assembly 80 may be provided with a slot into which a portion of the second circuit board 70 is inserted for connection with the connector assembly 80. This arrangement facilitates the connection between the connector assembly 80 and the second circuit board 70 to supply power to the second light-emitting element 32.

[0131] It should be noted that when the second circuit board 70 includes a setting part 312 and a connecting part 313, the connecting part 313 is connected to the connector assembly 80.

[0132] The following description, with reference to Figures 1 to 21, illustrates the module installation method of the buttons provided in some embodiments:

[0133] During the installation of the button module, the light guide 41 and the light guide base 42 can be connected through the first circuit board 31. Then, the button rod 11 is passed through the first through hole 411, the second through hole 421 and the third through hole 311, and the pressing component 10 is located in the relief groove 413 on the light guide 41. Then, one end of the button rod 11 is embedded in the connecting groove 601 on the pusher 60, and the pusher 60 is abutted against the pressable part 21. Finally, the light guide base 42 is snapped into the power connector 23.

[0134] In some embodiments, since the light guide assembly 40 has a receiving cavity and a through hole, the push assembly 10 can be inserted through the through hole, and the power assembly 20 can be placed outside the receiving cavity, with the push assembly 10 abutting against the power assembly 20. Since at least a portion of the light-emitting module 30 is located in the receiving cavity, the light emitted by the light-emitting module 30 can illuminate the light guide assembly 40. Since the power assembly 20 includes a pressable part 21, a first light-emitting part 22, and a power connector 23, the first light-emitting part 22 is connected to the power connector 23, the pressable part 21 is provided with a light-transmitting hole 211, the pressable part 21 is connected to the power connector 23, and the first light-emitting part 22 faces the light-transmitting hole 211, therefore, the light emitted by the first light-emitting part 22 can illuminate the light-transmitting hole 211. Since the push assembly 10 abuts against the pressable part 21 and the push assembly 10 can guide light, and the push assembly 10 covers at least part of the light-transmitting hole 211, when the push assembly 10 is pressed, the push assembly 10 can press the pressable part 21, thereby the pressable part 21 applies force to the power connector 23, and the power connector 23 can perform the corresponding operation after receiving the force. Since the first light-emitting part 22 indicates the power-on status of the server and the light-emitting module 30 indicates the operating status of the server, when the button module is installed on the ear structure and the ear structure is connected to the server, the operator can press the push component 10, which will apply force to the pressable part 21. The pressable part 21 will then apply force to the power connector 23, which will then power the server. During this process, the first light-emitting part 22 will also produce different colors depending on the power-on status of the server. The light emitted by the first light-emitting part 22 will shine on the push component 10, so the operator can see the light of the first light-emitting part 22 through the button cap and know the power-on status of the server. The light-emitting module 30 will also emit light, and the light of the light-emitting module 30 will shine on the light guide component 40, so the operator can also see the light of the light-emitting module 30 through the light guide component 40 and know the operating status of the server. In some embodiments, by providing a first light-emitting part 22 in the power connector 23 of the button module, and providing a light guide component 40 and a light-emitting module 30, it is equivalent to integrating the light-emitting module 30 and the light guide component 40. Thus, the button module not only has button functions, but also indicates the power-on status or running status of the service, thereby diversifying the functions of the button module and making it easier for operators to know the status of the server.

[0135] In some embodiments, a box ear structure is provided, which includes a box ear shell 100 and a button module as described in any of the above embodiments, wherein the button module is mounted on the box ear shell 100.

[0136] In some embodiments, since the light guide assembly 40 has a receiving cavity and a through hole, the push assembly 10 can be inserted through the through hole, and the power assembly 20 can be placed outside the receiving cavity, with the push assembly 10 abutting against the power assembly 20. Since at least a portion of the light-emitting module 30 is located in the receiving cavity, the light emitted by the light-emitting module 30 can illuminate the light guide assembly 40. Since the power assembly 20 includes a pressable part 21, a first light-emitting part 22, and a power connector 23, the first light-emitting part 22 is connected to the power connector 23, the pressable part 21 is provided with a light-transmitting hole 211, the pressable part 21 is connected to the power connector 23, and the first light-emitting part 22 faces the light-transmitting hole 211, therefore, the light emitted by the first light-emitting part 22 can illuminate the light-transmitting hole 211. Since the push assembly 10 abuts against the pressable part 21 and the push assembly 10 can guide light, and the push assembly 10 covers at least part of the light-transmitting hole 211, when the push assembly 10 is pressed, the push assembly 10 can press the pressable part 21, thereby the pressable part 21 applies force to the power connector 23, and the power connector 23 can perform the corresponding operation after receiving the force. Since the first light-emitting part 22 indicates the power-on status of the server and the light-emitting module 30 indicates the operating status of the server, when the button module is installed on the ear structure and the ear structure is connected to the server, the operator can press the push component 10, which will apply force to the pressable part 21. The pressable part 21 will then apply force to the power connector 23, which will then power the server. During this process, the first light-emitting part 22 will also produce different colors depending on the power-on status of the server. The light emitted by the first light-emitting part 22 will shine on the push component 10, so the operator can see the light of the first light-emitting part 22 through the button cap and know the power-on status of the server. The light-emitting module 30 will also emit light, and the light of the light-emitting module 30 will shine on the light guide component 40, so the operator can also see the light of the light-emitting module 30 through the light guide component 40 and know the operating status of the server. In some embodiments, by providing a first light-emitting part 22 in the power connector 23 of the button module, and providing a light guide component 40 and a light-emitting module 30, it is equivalent to integrating the light-emitting module 30 and the light guide component 40. Thus, the button module not only has button functions, but also indicates the power-on or running status of the service, thereby diversifying the functions of the button module and making it easier for operators to know the status of the server. Once the box-ear structure is applied to the server, the operator can directly know the status of the server, making it convenient for the operator to perform other operations based on the status of the server.

[0138] With this configuration, the housing 100 can protect the power supply component 20, and the light guide component 40 is installed in the mounting hole so that the button slot faces the outside of the housing 100, making it easy for the operator to press and operate the component 10, and also making it easy for the operator to know the status of the server by pressing the component 10.

[0139] In some embodiments, a server is provided, which includes a server housing 200 and a case ear structure as described in any of the above embodiments; the case ear shell 100 is connected to the server housing 200.

[0140] In some embodiments, a controller (not shown in the figure) is provided in the server housing 200. The controller is electrically connected to the light-emitting module 30 of the button module. The controller is used to obtain the operating status of the server and control the light-emitting module 30 to emit light according to the operating status.

[0141] The controller can be a control circuit board with control functions, which may integrate a central processing unit or a control chip.

[0142] Additionally, the controller can be electrically connected to the second circuit board 70 of the button module, thereby connecting to the connector assembly 80. Once the connection portion 313 of the first circuit board 31 is connected to the connector assembly 80, the controller can control the second light-emitting element 32 on the first circuit board 31. Furthermore, the controller can be electrically connected to the power connector 23. The controller can be electrically connected to the second circuit board 70 via a cable (not shown in the figure) or to the power connector 23 via a cable.
