[0025] Hereinafter, embodiments of the present application will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present application. In the following detailed description, for the sake of explanation, numerous specific details are set forth in order to provide a comprehensive understanding of the embodiments of the present application. However, obviously, one or more embodiments can also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of the present application.

[0026] The terms used herein are merely for describing specific embodiments and are not intended to limit the present application. The terms "including", "comprising", etc. used herein indicate the presence of the described features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0027] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0028] In the case of using expressions such as "at least one of A, B, and C, etc.", generally, it should be interpreted according to the meaning commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include, but is not limited to, a system having only A, only B, only C, having A and B, having A and C, having B and C, and / or having A, B, and C, etc.).

[0029] In the process of implementing the concept of the present application, the inventors found that for electrical equipment that is far from the power supply end of the server cabinet, the distance for the supplied current to reach the electrical equipment from the power supply end of the server cabinet is relatively long. Since the copper-clad trace of the PCB (printed circuit board) is relatively thin, it has a relatively large impedance and inductive reactance. The impedance will cause transmission loss, and the inductive reactance will cause electromagnetic interference. Thus, when using copper-clad traces to supply power to electrical equipment over a long distance, the power supply quality is relatively poor.

[0030] In view of this, embodiments of the present application provide a power supply device to improve the power supply quality for server nodes.

[0031] Figure 1 Schematically shows a schematic diagram of the power supply device according to an embodiment of the present application. As Figure 1 shown, the power supply device 100 of this embodiment includes a power supply cabinet body 110, a first conductive tray 120, and a second conductive tray 130.

[0032] The power supply cabinet body 110 may be the cabinet body of a server cabinet. The power supply end of the power supply cabinet body 110 can output a power supply voltage. The first conductive tray 120 is disposed inside the power supply cabinet body 110 and is in electrical contact with the power supply cabinet body 110. In this way, the first conductive tray 120 can receive voltage from the power supply cabinet body 110. The first conductive tray 120 can be used to support the second conductive tray 130 and is in electrical contact with the second conductive tray 130. Specifically, the first conductive tray 120 includes a conductive track 121 extending along the first direction X. The second conductive tray 130 is supported by the conductive track 121 and is in electrical contact with the conductive track 121. In this way, the first conductive tray 120 can provide the voltage from the power supply cabinet body 110 to the second conductive tray 130. The second conductive tray 130 is used to support the circuit board 140 and is in electrical contact with the circuit board 140. In this way, the voltage output by the power supply cabinet body 110 can be provided to the circuit board 140 for power supply via the first conductive tray 120 and the second conductive tray 130. The circuit board 140 may be, for example, the above-mentioned server node. For example, the material of the first conductive tray 120 may include a conductive material such as copper. In this way, it can be ensured that the first conductive tray 120 has good electrical conductivity and mechanical strength, and can support the second conductive tray 130 and the circuit board 140 on the second conductive tray 130. Similarly, the material of the second conductive tray 130 may also include a conductive material such as copper so as to better support the circuit board 140. However, the embodiments of the present application are not limited thereto, and new high-performance conductive materials such as nano-conductive coatings may also be used to manufacture the first conductive tray 120 and the second conductive tray 130, so that the first conductive tray 120 and the second conductive tray 130 have lower resistance, higher electrical conductivity, and better corrosion resistance.

[0033] The second conductive tray 130 can move relative to the first conductive tray 120 along the above-mentioned conductive track 121 in the above-mentioned first direction X, and the circuit board 140 and the second conductive tray 130 are relatively fixed. In this way, when the second conductive tray 130 moves along the first direction X on the conductive slide rail of the first conductive tray 120, the circuit board 140 can be driven to move in the first direction X. The moving direction can be along Figure 1 the left direction inFigure 1 The direction to the right in the middle.

[0034] It should be understood that when the second conductive tray 130 drives the circuit board 140 to move leftward on the conductive slide rail, the overlapping area between the orthographic projection of the first conductive tray 120 in the vertical direction Z (the projection plane is the upper surface of the first conductive tray 120, and the same applies hereinafter) and the orthographic projection of the second conductive tray 130 in the vertical direction Z (the projection plane is the upper surface of the first conductive tray 120, and the same applies hereinafter) shows an increasing trend; when the second conductive tray 130 drives the circuit board 140 to move rightward on the conductive slide rail, the overlapping area between the orthographic projection of the first conductive tray 120 in the vertical direction Z and the orthographic projection of the second conductive tray 130 in the vertical direction Z shows a decreasing trend.

[0035] During the process of installing the circuit board 140 inside the power supply cabinet 110, the second conductive tray 130 carries the circuit board 140 and slides inside the power supply cabinet 110 along the conductive track 121 of the first conductive tray 120, reducing the installation friction, thereby reducing the installation difficulty. When the area of the overlapping area is the largest (that is, Figure 1 when the left boundary of the second conductive tray 130 is flush with the left boundary of the first conductive tray 120 in the vertical direction Z), it can be determined that the second conductive tray 130 has slid to the target position. In this case, since the entire conductive track 121 extending along the first direction X can supply power to the second conductive tray 130, the second conductive tray 130 can receive a relatively good power supply voltage over a large area. Thus, by supplying power to the circuit board 140 through the second conductive tray 130 over a large area, the distance between the power-consuming device of the circuit board 140 and the power supply part is shortened, the power loss and electromagnetic interference during the power transmission process are reduced, the power supply efficiency and power supply stability are improved, and thus the power supply quality of the circuit board 140 is improved. Moreover, this method does not occupy the space of the circuit board 140, achieving the improvement of the power supply quality of the circuit board 140 while saving the space of the circuit board 140, so that the design difficulty and production cost of the circuit board 140 wiring can be reduced.

[0036] It should be added that during the process of installing the circuit board 140 into the power supply cabinet 110, the circuit board 140 moves Figure 1 leftward in the middle; during the process of removing the circuit board 140 from the power supply cabinet 110, the circuit board 140 moves Figure 1 rightward in the middle. This is only an example and is not used to limit the solution of this application.

[0037] Figure 2A Schematically shows a cross-sectional view of the conductive track in the first direction X according to an embodiment of the present application. Figure 2B Schematically shows a top view of the conductive track according to an embodiment of the present application.

[0038] As Figure 2A and Figure 2B shown, there are a conductive housing 211, a conductive shaft 212, and a conductive pulley 213. An insulating housing surrounding the conductive housing 211 can be provided outside the conductive housing 211 to prevent electrical connection to other positions of the first conductive tray via the conductive housing 211, causing a short circuit. A conductive shaft 212 is provided inside the conductive housing 211. The conductive pulley 213 has a hollow structure. Thus, the conductive pulley 213 can be sleeved on the conductive shaft 212. Multiple conductive pulleys 213 sleeved on the same conductive shaft 212 can form a set of pulley rows. Each conductive track can include multiple sets of pulley rows arranged in the second direction Y. On this basis, multiple sets of pulley rows can be provided inside the conductive housing 211.

[0039] The conductive shaft 212 can extend in a second direction Y that intersects (e.g., is perpendicular to) the first direction X. Both ends of the conductive shaft 212 can be respectively fixed to two opposite surfaces inside the conductive housing 211. Thus, when the conductive pulley 213 rotates around the conductive shaft 212, it can drive the second tray to move relative to the first conductive tray in the first direction X. When the second conductive tray is moved in the first direction X via the conductive pulley 213, the frictional force between the first conductive tray and the second conductive tray is small, reducing the mutual wear between the first conductive tray and the second conductive tray, improving the durability between the first conductive tray and the second conductive tray, and reducing the difficulty of inserting or removing the first conductive tray or the second conductive tray into or out of the power supply cabinet, making it more labor-saving. Moreover, the conductive track formed by the conductive frame, the conductive shaft 212, and the conductive pulley 213 has a certain thickness in the vertical direction Z. Compared with the copper-clad thin layer, it can transmit a larger current, thereby improving the power supply quality.

[0040] Optionally, the material of the conductive shaft 212 is an elastic material. Thus, when the first conductive tray supports the second conductive tray, the conductive pulley 213 and the conductive shaft 212 will be subjected to a force from the second conductive tray, causing the conductive shaft 212 to deform. In this way, it can be ensured that the conductive frame can fit the lower surface of the first conductive tray with the largest possible contact area, which helps to improve the stability and reliability of power transmission between the first conductive tray and the second conductive tray, and can reduce problems such as increased resistance or power transmission interruption caused by poor contact.

[0041] Optionally, the first conductive tray further includes: a communication module and a first controller. For example, the communication module can send a control instruction to the first controller in response to a user operation. When the first controller receives the control instruction, it controls the rotation of the conductive pulley 213 according to the control instruction, so as to drive the second conductive tray to move in the first direction X. In this way, the convenience of taking out the circuit board from the power supply cabinet or installing it into the power supply cabinet is improved. Similarly, the communication module can also be arranged on the circuit board, and the present application does not limit this.

[0042] Optionally, the conductive pulley 213 and the conductive shaft body 212 can be designed to be adjustable in height in the vertical direction Z, and the spacing between the rows of conductive pulleys 213 in the second direction Y can be designed to be adjustable, so as to adapt to circuit boards of different sizes and specifications, and reduce the problem of difficult installation of the circuit board caused by the size difference of the circuit board.

[0043] Figure 3 Schematically shows a top view of a plurality of conductive tracks according to an embodiment of the present application. As Figure 3 shown, a tray connecting member is provided on the outer surface of the conductive frame. The tray connecting member is in electrical contact with the power supply connecting member of the power supply cabinet. For example, the tray connecting member can be a crown clip. The crown clip can clamp the power supply connecting member of the power supply cabinet. In this way, the voltage of the power supply cabinet can be transmitted to the conductive frame. Two opposite surfaces inside the conductive frame are respectively connected to both ends of the above-mentioned conductive shaft body. In this way, the electrical contact between the conductive frame and the above-mentioned conductive shaft body can enable the voltage of the conductive frame to be transmitted to the conductive shaft body and further transmitted to the conductive pulley. In this way, the second conductive tray can be powered via multiple groups of conductive pulley rows of the conductive track, thereby shortening the distance between the power supply position and the power-consuming end of the circuit board and improving the power supply quality.

[0044] There can be multiple conductive tracks. The multiple conductive tracks include a first conductive track 310 and a second conductive track 320. The first conductive track 310 is connected to the first power supply end of the above-mentioned power supply cabinet, and the second conductive track 320 is connected to the second power supply end of the above-mentioned power supply cabinet. The polarities of the voltages output by the first power supply end and the second power supply end are different. The power supply end here is the above-mentioned power supply connecting member.

[0045] For example, the output voltage of the first power supply end can be a positive voltage (+), and the voltage output by the second power supply end can be a negative voltage (-). In Figure 3Among the three conductive tracks shown, the current direction can be from the first power supply terminal to the first conductive track 310 in the middle, then from the first conductive track 310 in the middle to the circuit board, and then from the circuit board to the second conductive tracks 320 on both sides, and then flow to the second power supply terminal via the second conductive tracks 320, thus forming a complete power supply loop. It should be understood that the number of conductive tracks here is only an example and is not used to limit the solution of this application. The first conductive track 310 and the second conductive tracks 320 are alternately arranged in the second direction Y, which expands the power supply positions in the second direction Y, can shorten the distance between the electrical equipment and the conductive tracks in the second direction Y, reduces the loss and electromagnetic interference during the power transmission process, improves the power supply efficiency and power supply stability, and thus improves the power supply quality to the circuit board.

[0046] Figure 4 Schematically shows a schematic diagram of a power supply device according to another embodiment of the present application. As Figure 4 shown, the tray connecting member 411 of the first conductive tray 410 is in electrical contact with the power supply connecting member 421 of the power supply cabinet 420, so that the output voltage of the power supply cabinet 420 can be transmitted to the first conductive tray 410. The conductive pulley 412 of the first conductive tray 410 can support the second conductive tray 430 and is in electrical contact with the second conductive tray 430, so that the voltage is transmitted to the circuit board 440 via the second conductive tray 430.

[0047] Figure 5A Schematically shows a top view of a second conductive tray according to an embodiment of the present application, Figure 5B Schematically shows a schematic diagram of a conductive track supporting a second conductive tray according to an embodiment of the present application. As Figure 5A and Figure 5B shown, the second conductive tray 510 includes a conductive area and an insulating area. The conductive area includes a conductive plate body 511 and a conductive support member 513. The insulating area includes an insulating frame 512.

[0048] The conductive support member is disposed on the upper surface of the conductive plate body 511 and is in electrical contact with the conductive plate body 511 via its lower surface, so that the voltage from the conductive plate body 511 can be received. The upper surface of the conductive support member 513 can be used to support the circuit board and is in electrical contact with the power-consuming end (i.e., the input end) of the circuit board, so that the power-consuming end of the circuit board can be directly powered, thereby reducing the power transmission loss.

[0049] The lower surface of the conductive plate body 511 may be provided with a protruding structure. The protruding structure and the lower surface of the conductive plate body 511 together form a guide groove extending along the second direction Y, so as to facilitate the conductive track to support and move the second conductive tray 510 in the guide groove, ensuring that there is no offset when the first conductive tray and the second conductive tray 510 move relative to each other, thereby avoiding the occurrence of short - circuit conditions. For example, multiple conductive tracks may respectively support the second conductive tray 510 in multiple guide grooves. The insulating frame 512 surrounds the outer periphery of the guide groove to ensure that the conductive area in the guide groove is not electrically connected to other positions of the second conductive tray 510, thereby causing a short - circuit. For example, the above - mentioned protruding structure may also be designed as an insulating structure. The second conductive tray 510 may include a conductive metal such as copper. In this way, the upper and lower surfaces of the second conductive tray 510 are smooth, which can reduce the contact resistance between the conductive pulley and the lower surface of the second conductive tray 510, as well as reduce the contact resistance between the conductive support 513 and the upper surface of the first conductive tray, reducing the power supply loss and improving the power supply quality.

[0050] Optionally, the circuit board may include a circuit controller. At least one of the first conductive tray and the second conductive tray 510 further includes a sensor. The sensor may be disposed in the conductive track or the guide groove. The sensor is connected to the circuit sensor and sends the electrical parameters of the first conductive tray and the second conductive tray 510 collected to the circuit controller. For example, the electrical parameters may include current values and so on. For example, when the circuit controller detects that the received current value is greater than or equal to a predetermined current threshold, it controls the circuit board to stop receiving the voltage from the second conductive tray 510. For example, it may be to control the electrical connection between the power - consuming end and the grounding end of the circuit board to avoid damage to the power - consuming equipment of the circuit board due to overload and so on. However, the embodiments of the present application are not limited thereto. Parameters such as voltage fluctuations and frequency changes can also be collected through the sensor. In the case of collecting these parameters, these parameters can be sent to the management system to timely detect problems of the circuit board and take corresponding measures to ensure the stable operation of the circuit board.

[0051] Figure 6 Schematically shows a schematic diagram of the second conductive tray supporting the circuit board according to an embodiment of the present application. As Figure 6 shown, in addition to the conductive support 611 between the second conductive tray 610 and the circuit board 620, fixing screws 630 may also be provided. The position relationship between the circuit board 620 and the second conductive tray 610 can be fixed through the fixing screws 630. For example, the second conductive tray 610 may be provided with fixing screw positioning holes, and the circuit board 620 may be provided with through - holes corresponding to the positions of the fixing screw positioning holes. In this way, the position relationship between the circuit board 620 and the second conductive tray 610 can be fixed by using the fixing screws 630 through the fixing screw positioning holes and the through - holes.

[0052] Figure 7 Schematically shows a schematic diagram of a power supply device according to another embodiment of the present application. As Figure 7 shown, the first conductive tray 720 and the second conductive tray 730 are assembled in the power supply cabinet 710. The power supply cabinet 710 is provided with cabinet fixing members. The first conductive tray 720 includes a first tray fixing member. The second conductive tray 730 includes a second tray fixing member. The cabinet fixing member and the first tray fixing member are adapted to each other. After the first conductive tray 720 is installed in the power supply cabinet 710, the cabinet fixing member and the first tray fixing member can be used to relatively fix the cabinet and the first conductive tray 720. Similarly, the second conductive tray 730 includes a second tray fixing member. The first tray fixing member and the second tray fixing member are adapted to each other. After both the first conductive tray 720 and the second conductive tray 730 are installed in the power supply cabinet 710, the first tray fixing member and the second tray fixing member can be used to relatively fix the first conductive tray 720 and the second conductive tray 730. In this way, the structural stability among the first conductive tray 720, the second conductive tray 730, and the power supply cabinet 710 can be ensured.

[0053] For example, the cabinet fixing member can be provided on the surface of the power supply cabinet 710. For example, it can be the surface for installing the first conductive tray 720 and the second conductive tray 730 (such as Figure 7 the surface shown). The first tray fixing member and the second tray fixing member can be provided on the surface on the same side as the cabinet fixing member (such as Figure 7 the surface shown). For example, the cabinet fixing member, the first tray fixing member, and the second tray fixing member can be hooks.

[0054] In the case where maintenance is required for the first conductive tray 720, the second conductive tray 730, and the circuit board, the hooks fixing the first conductive tray 720, the second conductive tray 730, and the circuit board can be opened, so as to take out the part to be maintained. And, handles are respectively designed on both sides of the first conductive tray 720 and the second conductive tray 730, which is convenient for relevant personnel to disassemble or install the first conductive tray 720 or the second conductive tray 730 respectively.

[0055] Optionally, the second conductive tray 730 includes a trigger. When the trigger is triggered, the trigger can send a trigger signal to the circuit board. Specifically, it can be to send a trigger signal to the hot-swap circuit in the circuit board. The hot-swap circuit can be used to implement the hot-swap function of the circuit board. When the circuit controller of the circuit board receives the above trigger signal and the hot-swap circuit is disconnected from the ground terminal, it controls the electrical connection between the enable terminal of the hot-swap circuit and the ground terminal so that the hot-swap function of the hot-swap circuit becomes effective, and when it receives the above trigger signal and the hot-swap circuit is electrically connected to the ground terminal, it controls the disconnection of the electrical connection between the enable terminal of the hot-swap circuit and the ground terminal so that the hot-swap function of the hot-swap circuit becomes ineffective.

[0056] For example, when it is necessary to install the circuit board inside the power supply cabinet 710, it is necessary to disable the hot-swap circuit through a trigger signal. In this way, during the process of the second conductive tray 730 carrying the circuit board and sliding into the power supply cabinet 710 via the conductive rail, the conductive rail can charge the capacitor in the circuit board via the second conductive tray 730. When the second conductive tray 730 slides into place, the hot-swap circuit is then controlled to be powered on through the trigger signal. In this way, through the electric energy pre-charged in the capacitor, the occurrence of uncontrollable surge current can be avoided during the slow power-on process of the hot-swap circuit, reducing the risk of the circuit board generating surge current and the high-voltage risk of the components of the circuit board, and improving the stability of power supply to the circuit board. In this way, the trigger can be triggered before the overlapping area between the orthographic projection of the first conductive tray 720 in the vertical direction Z and the orthographic projection of the second conductive tray 730 in the vertical direction Z increases (i.e., before the second conductive rail carries the circuit board and slides into the power supply cabinet 710), or can be triggered when the overlapping area remains unchanged (i.e., after the second conductive rail slides into place). For example, the trigger can be a button provided on the surface of the first conductive tray 720 (such as Figure 7 the surface shown). When the relevant person presses this button, a trigger signal can be generated.
