Description

Technical Field

[0001] The present invention relates to the technical field of server power supply, and in particular to a server power supply device. In addition, the present invention also provides a server comprising the server power supply device. Background Art

[0002] In recent years, with the rapid development of artificial intelligence technology, society's demand for server computing power has been growing, server performance has increased rapidly, and the scale of computer rooms has also increased accordingly, which has also brought about the problem of increased server power consumption.

[0003] At present, one of the traditional power supply methods is CRPS distributed power supply (Common Redundancy Power Supply). CRPS distributed power supply provides redundant power supply. Even if one power supply fails, another power supply can continue to supply power, thereby ensuring the continuous operation of the equipment. However, there is a problem of maximum power limitation. The other is centralized power supply, which provides power supply to multiple devices through specific equipment and systems. This power supply method is insufficient in conversion rate.

[0004] When the power consumption of the server further increases, more power supply modules are needed to provide power to the server system. In the process of increasing the number of power supply modules, since the power supply modules are basically of standard structure and cannot be matched according to the power consumption of the server, there is a situation where the actual power supply capacity of all power modules does not match the power consumption of the server, which can easily cause waste of electricity or affect the normal operation of the server.

[0005] In summary, how to provide a server power supply device that can match a power module according to the actual power consumption of the server is a technical problem that needs to be urgently solved by those skilled in the art. Summary of the invention

[0123] Furthermore, the active guide member can include a connecting guide rod 3-3-1-1 and a tilting guide rod 3-3-1-2, one end of the connecting guide rod 3-3-1-1 is connected to the operating module 3-4, the other end of the connecting guide rod 3-3-1-1 is connected to the tilting guide rod 3-3-1-2, and the length direction of the tilting guide rod 3-3-1-2 has extensions along the first direction and the second direction at the same time; the first slide groove 3-3-1-3 is arranged on the second radiator 3-2-3, the first slide groove 3-3-1-3 is sleeved on the outer periphery of the tilting guide rod 3-3-1-2, and the tilting guide rod 3-3-1-2 can be slidably arranged relative to the first slide groove 3-3-1-3.

[0124] In actual use, when the DC power supply device 3 needs to be installed, first, the cross beam 3-3-2-1 of the DC power supply device 3 needs to correspond to the first slideway of the top cover 1-2, and then the DC power supply device 3 needs to be pushed toward the inside of the device housing 1 to make the cross beam 3-3-2-1 slide along the first slideway. At the same time, the DC power supply device 3 moves toward the inside of the device housing 1. During this process, the inclined guide rod 3-3-1-2 slides relative to the first slide groove 3-3-1-3. Since the extension direction of the inclined guide rod 3-3-1-2 has components of the first direction and the second direction at the same time, during the sliding process of the inclined guide rod 3-3-1-2 relative to the first slide groove 3-3-1-3, the first slide groove 3 -3-1-3 moves along the first direction and moves downward along the second direction. Since the first slide groove 3-3-1-3 is set on the second radiator 3-2-3, the second radiator 3-2-3 moves along the first direction and moves along the second direction close to the DC power connector. During the movement of the second radiator 3-2-3 along the second direction, the second slide slides along the second direction relative to the longitudinal beam 3-3-2-2. The cooperation between the second slide and the longitudinal beam 3-3-2-2 plays a guiding role. The second radiator 3-2-3 drives the gold finger plate 3-1-1 to move along the first direction and the second direction, thereby realizing the plug-in cooperation between the gold finger of the gold finger and the DC power connector.

[0125] like Fig.15 As shown, one end of the second radiator 3-2-3 is provided with a Z-shaped bending structure, the Z-shaped bending structure is provided with an inclined inclined surface, the first slide groove 3-3-1-3 is an annular structure, and the first slide groove 3-3-1-3 of the annular structure can be sleeved on the outer periphery of the inclined guide rod 3-3-1-2.

[0126] In this specific embodiment, the second heat sink 3-2-3 is driven to move along the tilting direction of the tilting guide rod 3-3-1-2 through cooperation with the first slide groove 3-3-1-3, so that the moving direction of the second heat sink 3-2-3 has both the first direction component and the second direction component; and because the second heat sink 3-2-3 is fixedly connected to the gold finger plate 3-1-1, the moving direction of the gold finger plate 3-1-1 has both the first direction component and the second direction component, so that the second heat sink 3-2-3 can move along the first direction. When the operating module 3-4 is pushed inward, the gold finger plate 3-1-1 moves along the first direction toward the inner side of the device housing 1 and along the second direction toward the side close to the DC power connector, thereby realizing the plug-in fit between the gold finger plate 3-1-1 and the DC power connector; when the operating module 3-4 is pulled outward along the first direction, the gold finger plate 3-1-1 moves along the first direction toward the outer side of the device housing 1 and along the second direction toward the side away from the DC power connector, thereby realizing the release of the plug-in fit between the gold finger plate 3-1-1 and the DC power connector.

[0127] In the present specific embodiment, during the process of plugging and mating the DC power supply device 3 with the DC power connector or releasing it, it is only necessary to push the DC power supply device 3 inwardly along the first direction or pull the DC power supply device 3 outwardly along the first direction, and there is no need to disassemble the device housing 1 for operation, which makes the installation and removal process of the DC power supply device 3 more convenient and easy to operate.

[0128] On the basis of the above embodiments, the operating module 3-4 can include an operating shell 3-4-1 and a locking assembly; the crossbeam 3-3-2-1 is fixedly connected to the operating shell 3-4-1; the active guide is movably arranged on the operating shell 3-4-1 along a first direction between a first position and a second position; when the active guide moves to the first position, the plug-in portion and the DC power connector are released from the plug-in connection; when the active guide moves to the second position, the plug-in portion and the DC power connector are plug-matched; the locking assembly is arranged on the operating shell 3-4-1, and when the active guide moves to the first position, the locking assembly and the active guide are unlocked; when the active guide moves to the second position, the locking assembly and the active guide are locked and fixed.

[0129] Specifically, the locking assembly can include a locking buckle 3-4-3, a first elastic return member 3-4-4, and an unlocking button 3-4-5; wherein the locking buckle 3-4-3 is rotatably arranged on the operating shell 3-4-1, one of the locking buckle 3-4-3 and the active guide member is provided with a locking protrusion 3-4-3-1, and the other of the locking buckle 3-4-3 and the active guide member is provided with a locking groove 3-3-1-4 for cooperating with the locking protrusion 3-4-3-1 for locking; one end of the first elastic return member 3-4-4 abuts against the operating shell 3-4-1, and the other end abuts against the locking buckle 3-4-3; the unlocking button 3-4-5 is rotated along the first elastic return member The extension direction of the component 3-4-4 is movably arranged on the operating shell 3-4-1 between the third position and the fourth position, and the unlocking button 3-4-5 is connected to the locking buckle 3-4-3; the locking buckle 3-4-3 is rotatably arranged between the first angle position and the second angle position; when the locking buckle 3-4-3 is located at the first angle position, the unlocking button 3-4-5 is located at the third position, and the locking protrusion 3-4-3-1 and the locking groove 3-3-1-4 cooperate to lock; when the locking buckle 3-4-3 is located at the second angle position, the unlocking button 3-4-5 is located at the fourth position, and the locking protrusion 3-4-3-1 and the locking groove 3-3-1-4 are unlocked.

[0130] On the basis of the above embodiment, the operating module 3-4 can also include a guide assembly, the operating shell 3-4-1 includes a first shell and a second shell that are snap-fitted, and the inner sides of the first shell and the second shell are both provided with a second slide groove 3-4-9 extending along the first direction; the guide assembly includes a roller 3-4-6, a guide column 3-4-7 and a second elastic return member 3-4-2, the roller 3-4-6 is arranged at one end of the active guide member and can be slidably arranged along the extension direction of the second slide groove 3-4-9, the length direction of the guide column 3-4-7 is arranged along the extension direction of the second slide groove 3-4-9, one end of the second elastic return member 3-4-2 abuts against the inner side wall of the second slide groove 3-4-9, and the other end abuts against the guide column 3-4-7.

[0131] like Fig.16 , Fig.17 As shown, the inclined guide rod 3-3-1-2, the connecting guide rod 3-3-1-1 and the rod-shaped part of the guide assembly are an integrated structure, and the rod-shaped part of the guide assembly is provided with a mounting block, and the opposite sides of the mounting block are provided with rollers 3-4-6, the axial direction of the roller 3-4-6 is perpendicular to the first direction, and the axial direction of the guide column 3-4-7 is arranged along the first direction; the operating shell 3-4-1 is provided with an operating handle 3-4-8 connected to the active guide member, the operating handle 3-4-8 is in a C-shaped structure, and the inner side of the operating handle 3-4-8 is provided with a contoured recess for easy gripping.

[0132] like Fig.19 As shown, the operating shell 3-4-1 is provided with a clamping portion for fixedly connecting with the crossbeam 3-3-2-1 of the first guide device 3-3-2, so that the first guide device 3-3-2 can move synchronously with the operating shell 3-4-1; the operating shell 3-4-1 is provided with a mounting position for installing the second guide device 3-3-1, so that the operating shell 3-4-1 can include a first shell and a second shell that are snap-fitted together. In actual use, the second guide device 3-3-1 can be clamped between the first shell and the second shell.

[0133] like Fig. 22 , Fig.25As shown, at this time, the DC power supply device 3 is not plugged into the DC power connector. In actual use, it is first necessary to make the crossbeam 3-3-2-1 correspond to the C-shaped slide rail 1-2-2 of the top cover 1-2, and then hold the operating handle 3-4-8 to push the operating module 3-4 inward, and the operating module 3-4 drives the second guide device 3-3-1 to move along the first direction. During the movement of the second guide device 3-3-1 along the first direction, due to the cooperation between the first slide groove 3-3-1-3 and the inclined guide rod 3-3-1-2 in the second guide device 3-3-1, during the movement of the second guide device 3-3-1 along the first direction, the second heat sink 3-2-3 equipped with the first slide groove 3-3-1-3 will be driven to move along the first direction, and the second heat sink 3-2-3 will move downward along the second direction until the gold finger plate 3-1-1 is plugged and matched with the DC power connector. At this time, as shown in FIG. Fig.23 , Fig.24 As shown, the locking recess of the second guide device 3-3-1 cooperates with the locking protrusion 3-4-3-1 on the locking buckle 3-4-3 to lock, and under the elastic force of the first elastic reset member 3-4-4, the locking cooperation between the second guide device 3-3-1 and the locking buckle 3-4-3 is achieved.

[0134] When the locking cooperation between the second guide device 3-3-1 and the locking buckle 3-4-3 needs to be released, the unlocking button 3-4-5 is pressed along the first direction. The contact position between the unlocking button 3-4-5 and the locking buckle 3-4-3 deviates from the rotation axis of the locking buckle 3-4-3. Therefore, during the process of pressing the unlocking button 3-4-5, Fig.23 The locking buckle 3-4-3 overcomes the elastic force of the first elastic reset member 3-4-4 and rotates clockwise until the locking protrusion 3-4-3-1 of the locking buckle 3-4-3 is disengaged from the locking groove 3-3-1-4 of the second guide device 3-3-1. At this time, the operating handle 3-4-8 can be pulled outward along the first direction. At the same time, under the elastic force of the second elastic reset member 3-4-2, the second guide device 3-3-1 moves outward along the first direction. During the process of the second guide device 3-3-1 moving outward along the first direction, due to the elastic force of the first slide groove 3-3-1-3 and the second guide device 3-3-1, the locking buckle 3-4-3 is disengaged from the locking groove 3-3-1-4 of the second guide device 3-3-1. The cooperation of the inclined guide rod 3-3-1-2 will drive the second heat sink 3-2-3 installed with the first slide groove 3-3-1-3 to move outward in the first direction, and at the same time, the second heat sink 3-2-3 moves upward in the second direction. Because the second heat sink 3-2-3 is fixedly connected to the gold finger plate 3-1-1, the gold finger plate 3-1-1 is driven to move outward in the first direction, and at the same time, the gold finger plate 3-1-1 moves upward in the second direction, so that the gold finger plate 3-1-1 is unplugged from the DC power connector. Continuing to pull the operating handle 3-4-8 outward, the DC power supply device 3 can be taken out of the device housing 1.

[0135] It needs to be explained that if Fig. 22 , Fig.23 As shown, in this specific embodiment, the rotation axis of the locking buckle 3-4-3 is not colinear with the position in the locking buckle 3-4-3 that contacts the unlocking button 3-4-5, and the rotation axis of the locking buckle 3-4-3 is not colinear with the position in which the first elastic reset member 3-4-4 contacts the locking buckle 3-4-3. Therefore, under the elastic force of the first elastic reset member 3-4-4, the locking buckle 3-4-3 will generate Fig. 22 , Fig.23 The first elastic reset member 3-4-4 provides a locking force for the locking protrusion 3-4-3-1 of the locking buckle 3-4-3 and the locking recess of the second guide device 3-3-1. When the unlocking button 3-4-5 is pressed, the locking buckle 3-4-3 is locked. Fig. 22 , Fig.23 The tendency to rotate clockwise in the direction shown causes the locking protrusion 3-4-3-1 of the locking buckle 3-4-3 to be unlocked from the locking recess of the second guide device 3-3-1.

[0136] In this specific embodiment, by setting the unlocking button 3-4-5, the locking of the locking buckle 3-4-3 and the second guide device 3-3-1 can be easily contacted, and the operation is convenient. In addition, the setting of the locking buckle 3-4-3 can limit the position of the gold finger plate 3-1-1 in the first direction to avoid accidental separation of the gold finger plate 3-1-1 from the DC power connector.

[0137] In a specific embodiment, the power substrate 2 can include a substrate body, an external power connector 2-4, a capacitor 2-3, a relay 2-2, a connection part 2-1 and a DC power connector; wherein the external power connector 2-4 is installed on the substrate body; the capacitor 2-3 is installed on the substrate body for filtering and energy storage, and the capacitor 2-3 is electrically connected to the external power connector 2-4; the relay 2-2 is installed on the substrate body for controlling the on and off of the circuit; the connection part 2-1 is a power gold finger arranged on the substrate body; the DC power connector is arranged on the surface of one side of the substrate body in the thickness direction, and the DC power connector includes a primary side high voltage connector 2-5 and a secondary side low voltage connector 2-6; the external power connector 2-4, the capacitor 2-3, and the relay 2-2 are arranged in sequence along the same straight line.

[0138] like Fig. 9 As shown, in this specific embodiment, the external power connector 2-4, the capacitor 2-3, and the relay 2-2 are arranged in sequence along the same straight line, so that the structural layout of the power substrate 2 is more reasonable.

[0139] On the one hand, along the thickness direction of the substrate body, the power gold finger is located on the side of the substrate body where the DC power connector is provided; and the upper surface of the power gold finger is higher than the surface of the substrate body where the DC power connector is installed, and the lower surface of the power gold finger is higher than the surface of the substrate body away from the DC power connector.

[0140] In this specific embodiment, the power gold finger is higher than the substrate body, and the power gold finger is connected to the substrate body through a copper busbar, ensuring that the gold finger position of the server power supply device in this application is the same as that of the standard CRPS power module, and can be directly replaced, thereby reducing the height of the substrate body in the server power supply device and increasing the space above the substrate body. While ensuring the compatibility of the server power supply device, the internal space utilization rate of the device housing 1 is improved.

[0141] like Fig. 9 As shown, a avoidance groove 2-7 is arranged between adjacent DC power connectors, and the avoidance groove 2-7 includes a middle groove and end grooves arranged at both ends of the middle groove, the end grooves are connected to the middle groove, and the width of the end grooves is smaller than the width of the middle groove; the avoidance groove 2-7 extends along the length direction of the DC power connector, and the middle groove is located between the primary side high voltage connector 2-5 and the secondary side low voltage connector 2-6 in the same DC power connector; when the plug-in part is plugged into the DC power connector, the power board 3-1-2 is located in the avoidance groove 2-7.

[0142] In the actual assembly process, Fig.12 As shown, the size of the power board 3-1-2 in the direction perpendicular to the substrate body is larger than the size of the gold finger board 3-1-1 in the direction perpendicular to the substrate body, and the top of the power board 3-1-2 is aligned with the top of the gold finger board 3-1-1. When the gold finger board 3-1-1 is plugged into the DC power connector, the power board 3-1-2 is located in the avoidance groove 2-7, and the magnetic core installed on the power board 3-1-2 is not located in the middle groove.

[0143] In this specific embodiment, by providing the avoidance groove 2-7, the avoidance installation of the power board 3-1-2 can be better achieved to avoid interference.

[0144] In a specific embodiment, the device housing 1 can include a device base 1-1 and a detachable top cover 1-2 arranged on the upper opening of the base 1-1, the power substrate 2 is fixed to the device base 1-1, and the DC power connector of the power substrate 2 is arranged toward the top cover 1-2; at least one side of the device housing 1 is provided with an opening, and the DC power supply device 3 is inserted into the device housing 1 through the opening.

[0145] like Figure 4As shown, the bottom of the base 1-1 is provided with riveted studs 1-1-2, and the two sides of the base 1-1 are provided with riveted nuts 1-1-1. During the actual assembly process, the riveted studs 1-1-2 are used to be fixedly connected with the power substrate 2 to realize the positioning installation of the power substrate 2; the top cover 1-2 is fixedly connected with the base 1-1 through the riveted nuts 1-1-1.

[0146] A ventilation hole 1-2-1 is provided on the side of the device casing 1 opposite to the opening, and the first slide is a C-shaped slide rail 1-2-2 provided on the inner wall of the top cover 1-2; the setting of the ventilation hole 1-2-1 can realize smooth airflow through the device casing 1, which is beneficial to the heat dissipation of the server power supply equipment.

[0147] On the other hand, the height of the DC power supply device 3 can be made less than 1U. During the installation of the DC power supply device 3, the DC power supply device 3 can be directly installed from the opening side of the equipment casing 1 without disassembling the equipment casing 1, which simplifies the installation and disassembly process and facilitates operation.

[0148] During the installation and removal of the DC power supply device 3, generally, only one DC power supply device 3 can be installed or removed at a time. When the power consumption of the server is large and a large number of DC power supply devices 3 need to be installed, if only one DC power supply device 3 can be installed at a time, it takes a long time and is easy to affect work efficiency. Therefore, the server power supply device can also include a connecting component for connecting adjacent DC power supply devices 3. The connecting component is provided with a fixing buckle for fixed connection with the DC power supply device 3. When the plug-in portion is plugged into the DC power connector, a portion of the DC power supply device 3 located outside the device housing 1 is provided with a fixing slot for engaging with the fixing buckle. The connecting component is used to connect multiple DC power supply devices 3 as a whole. At the same time, the portion of the connecting component used for connecting with the DC power supply device 3 is connected to the portion of the DC power supply device 3 that does not need to extend into the device housing 1, which will not affect the normal installation and removal of the DC power supply device 3.

[0149] During actual use, when multiple DC power supply devices 3 need to be installed, the multiple DC power supply devices 3 can be connected into an integrated structure in advance through a linking component, and then the beams 3-3-2-1 of the multiple DC power supply devices 3 are made to correspond to the multiple first slides at the same time, and the multiple DC power supply devices 3 are pushed inward at the same time, so that the multiple DC power supplies move synchronously and the synchronous installation of the multiple DC power supplies is realized.

[0150] In this specific embodiment, by providing a connection component to combine multiple DC power supply devices 3 into an integrated structure, multiple DC power supply devices 3 can be installed simultaneously, which can effectively improve the installation efficiency of the DC power supply devices 3.

[0151] In a specific embodiment, the server power supply device also includes a first controller, the device housing 1 is provided with an in-place detection member, and the DC power connector is provided with a depth detection member for detecting the insertion depth of the plug-in part; the in-place detection member is used to obtain the distance information between the part of the DC power supply device 3 extending into the device housing 1 and the preset position, and transmit the obtained distance information to the first controller, the depth detection member is used to obtain the insertion depth information of the plug-in part inserted into the DC power connector, and transmit the insertion depth information to the first controller, and the first controller determines whether the plug-in part is plugged into the preset position based on the distance information and the insertion depth information.

[0152] Specifically, the in-place detection component can be set as a distance sensor, which can obtain the distance between the DC power supply device 3 and the target position in real time. When the distance between the DC power supply device 3 and the target position is zero, it means that the DC power supply device 3 has moved to the preset position; the depth detection component can be set as a pressure sensor. During actual use, when the plug-in part is inserted into the DC power connector, the plug-in part contacts the pressure sensor. The installation position of the pressure sensor is located at the preset plug-in position of the plug-in part. When the pressure detected by the pressure sensor changes significantly, indicating that the plug-in part is in contact with the pressure sensor, it means that the plug-in part has been inserted to the preset depth.

[0153] In this specific embodiment, by setting up a position detection member and a depth detection member, the distance information of the DC power supply device 3 extending into the equipment housing 1 and the plug-in information of the plug-in part can be obtained in time, and the installation status of the DC power supply device 3 can be fed back in time to facilitate the installation.

[0154] In a specific embodiment, the server power supply device also includes a display module arranged on the outside of the device housing 1 and a shooting module arranged inside the device housing 1, and the display module and the DC power connector are arranged in a one-to-one correspondence; it should be noted that, in this specific embodiment, the one-to-one correspondence between the display module and the DC power connector can be to set multiple display modules, each display module and the DC power connector are arranged in a one-to-one correspondence, or to set one display module, but the area for displaying information in the display module is divided into different display areas, and the display area and the DC power connector are arranged in a one-to-one correspondence, which is determined according to actual conditions and will not be elaborated here.

[0155] The shooting module is used to obtain first image information of the DC power connector and second image information of the DC power supply device 3 plugged into the DC power connector, and transmit the first image information and the second image information to the first controller; the first controller obtains the plug-in depth information of the plug-in part in the corresponding DC power connector and the status information of the DC power connector according to the first image information and the second image information, and controls the display module to display the plug-in depth information and the status information.

[0156] It should be noted that the state information of the DC power connector mentioned in this specific embodiment includes: whether the DC power connector is plugged with a plug part, the plugging posture information of the plug part in the DC power connector, whether there are impurities in the slot of the DC power connector, etc., which are determined according to actual conditions and will not be described in detail here. The plugging position of the plug part mentioned here includes the plugging position and plugging angle of the plug part.

[0157] During actual use, the first controller obtains the plugging depth information of the plug-in part in the corresponding DC power connector and the status information of the DC power connector based on the first image information and the second image information, and the display module displays the plugging depth information and the status information of the DC power connector, so that the operator can intuitively observe the plugging depth information and the status information of the DC power connector, which is conducive to timely feedback.

[0158] On the other hand, a display module can also be set on the external device, and the display module of the external device can be connected to the first controller. The first controller controls the display module of the external device to display the plug-in depth information and the status information of the DC power connector. The operator can intuitively observe the plug-in depth information and the status information of the DC power connector without opening the server.

[0159] On the basis of the above embodiment, relevant warning equipment may be further provided. When the DC power supply device 3 is not properly plugged in and an error occurs, the warning equipment may promptly issue a warning message so as to provide timely feedback to the operator.

[0160] In addition, in addition to the above-mentioned server power supply device, the present invention also provides a server including the server power supply device provided by the above-mentioned embodiment. The other structures of this server can refer to the prior art and will not be described in detail here.

[0161] During actual use of the server in this specific embodiment, the portion of the mainboard used for connecting to the power supply can retain the original structure, and the server power supply device provided in the above embodiment can directly replace the original power supply.

[0162] During actual use, the number of server power supply devices to be installed and the number of DC power supply devices 3 to be installed in the server power supply devices can be selected according to the actual power consumption of the server to avoid the situation where the actual power supply capacity of the power module does not match the server power consumption.

[0163] It should also be noted that, in this specification, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.
