Description

Technical Field

[0001] This application relates to the technical field of servers, and particularly to a server power protection device and a server. Background Art

[0002] The capacity of the server power module is a key factor to ensure the stable operation of the server. The overvoltage and overcurrent problems of the server are likely to cause damage to the power module and the subsequent devices, which are the main reasons affecting the operation of the server power supply. Usually, an overcurrent protection module and an overvoltage protection module are set, and then the two protection modules are switched to be connected to protect the server in two states respectively. That is, when an abnormal current is detected, it is switched to the overcurrent protection module, and when an abnormal voltage is detected, it is switched to the overvoltage protection module.

[0003] In some related technologies, usually the two protection modules are respectively installed at fixed positions to realize the protection of the server power supply. Their positions are fixed, which is not convenient for adjusting the occupied space, and it is not convenient for maintaining and replacing the protection modules. In addition, the switching process of the existing switching structure for the two protection modules is relatively long, resulting in low switching efficiency, and it is easy to have problems that the power module is damaged due to overcurrent or overvoltage during the switching process.

[0011] In a specific embodiment, the slideway is annular, the driving part is correspondingly arranged at the central position of the annular slideway, and the driving part drives the rotating rod to perform a circular motion around the central position of the slideway.

[0033] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0034] An embodiment of the present application provides a server power protection device, which is applied to a server, such as Figure 1As shown in the figure, it includes a bracket 1, a support slide rail 2, and an overcurrent and overvoltage protector 3. The bracket 1 is vertically installed in the server. In order to increase the stability of the bracket 1, the bottom of the bracket 1 is provided with a bottom carrier plate 4. The support slide rail 2 is vertically arranged and rotatably connected to the bracket 1, so that the support slide rail 2 can be rotationally adjusted around the central axis of the bracket 1 in the horizontal direction. At the same time, the overcurrent and overvoltage protector 3 is slidably installed on the support slide rail 2, and the overcurrent and overvoltage protector 3 is provided with an overvoltage protection module 5, an overcurrent protection module 6, and a switching component 7 installed between the overvoltage protection module 5 and the overcurrent protection module 6. The switching component 7 is connected to the overvoltage protection module 5 or the overcurrent protection module 6 through a connection circuit. At the same time, the switching component 7 is used to switch the connection circuit to communicate with the overvoltage protection module 5 or the overcurrent protection module 6 according to the power supply state of the server to realize the protection of the server power supply. By setting the overcurrent and overvoltage protector 3 for accommodating the overcurrent protection module 6 and the overvoltage protection module 5, it can be slidably adjusted along the bracket 1 to realize the adjustment of the position of the protection module. At the same time, the setting of the switching component 7 in the present application improves the switching efficiency.

[0035] As Figure 1 shown, a rotating block 8 is fixedly connected to the side wall of the bracket 1 for installing the support slide rail 2. A rotating frame 9 is rotatably installed on the side of the rotating block 8 away from the bracket 1. The rotating block 8 is strip-shaped, and both the top end and the bottom end of the rotating block 8 are connected to the rotating frame 9 through damping rotating shafts. A rotating frame 9 is rotatably installed on the side of the rotating block 8 away from the bracket 1, and the side of the rotating frame 9 away from the rotating block 8 is connected to the support slide rail 2, so as to realize that the support slide rail 2 can be rotationally adjusted around the central axis of the bracket 1 by a certain angle of rotation, so as to realize the adjustment of the overcurrent and overvoltage protector 3 on the arc line where the central axis of the bracket 1 is located. At the same time, under the action of the damping rotation, the overcurrent and overvoltage protector 3 has good stability when not rotating. A sliding channel 201 is opened on the inner side of the support slide rail 2, and end plates 10 are provided at both the top and bottom ends of the support slide rail 2 to close the top and bottom of the sliding channel 201 through the end plates 10.

[0036] Furthermore, installation holes 11 are also opened at the top and bottom of the bracket 1. The installation holes 11 are used to be connected and fixed to the installation rack in the server. During use, the connecting piece passes through the installation holes 11 and is fixedly connected to the vertical installation rack in the server to reduce the occupied space of the device. Or, it is connected to the wall through expansion screws, which can effectively reduce the space occupation during use. The bottom end of the bracket 1 is installed with a bottom carrier plate 4 to support the bracket 1. At the same time, the bottom of the support slide rail 2 can also be supported by the bottom carrier during rotation to improve the stability of the overcurrent and overvoltage protector 3 on one side of the bracket 1.

[0037] As Figure 2 andFigure 3 As shown in the figure, a sliding block 12 is also slidably connected to the support slide rail 2. One side of the sliding block 12 away from the support slide rail 2 is connected to a support frame 33. The support frame 33 is used to accommodate and fix the overcurrent and overvoltage protector 3, and is also passed through the support frame 33 by a positioning component 13 and inserted into a clamping hole 15 on the overcurrent and overvoltage protector 3 to position the overcurrent and overvoltage protector 3.

[0038] In this embodiment, as Figure 4 shown, the positioning component 13 includes a positioning plate 1301 and a sleeve 1302. The support frame 33 is L-shaped, and the side surface of the overcurrent and overvoltage protector 3 is rectangular, with the bottom side fitting against the bottom of the L-shaped support frame 33 and the side of the overcurrent and overvoltage protector 3 fitting against the side of the L-shaped support frame 33. The bottom side and the side of the L-shaped support frame 33 are both greater than or equal to the side length of the overcurrent and overvoltage protector 3. The positioning plate 1301 is fixedly connected to the support frame 33, and a plurality of them are respectively arranged at intervals along the side and the bottom of the support frame 33 and are distributed on both sides of the overcurrent and overvoltage protector 3. A sleeve 1302 is arranged on the side of the positioning plate 1301 away from the overcurrent and overvoltage protector 3. A positioning column 1303 is movably inserted into the sleeve 1302. The end of the positioning column 1303 is sequentially connected to a first elastic member 1304 and a positioning seat 1305. The overcurrent and overvoltage protector 3 has a housing 14, and a plurality of clamping holes 15 corresponding to the sleeves 1302 are formed along the edge of the housing 14. During use, the positioning column 1303 elastically penetrates through the sleeve 1302 and is inserted into the clamping hole 15 of the housing 14 of the overcurrent and overvoltage protector 3 to fix the overcurrent and overvoltage protector 3 located on the support frame 33. The installation and disassembly are convenient. The L-shaped support frame 33 can maintain the stability of the overcurrent and overvoltage protector 3 during use and reduce the risk of falling off.

[0039] As Figure 3 shown, a sliding block 12 is fixedly connected to the side of the support frame 33 close to the support slide rail 2. The sliding block 12 is slidably connected and fitted in the support slide rail 2. The cross-section of the sliding block 12 is T-shaped and is slidably fitted with a slideway 701 on the support slide rail 2.

[0040] To improve the smoothness of the sliding block 12 during sliding and reduce the impact of vibration on the over-current and over-voltage protector 3, on both side walls of the sliding block 12 close to the support slide rail 2, a first plate body 17, a guiding telescopic rod 18, and a second plate body 19 are sequentially connected respectively. A second elastic member 20 is also connected between the first plate body 17 and the second plate body 19. On the side of the second plate body 19 away from the first plate body 17, pulleys 21 are installed. A plurality of pulleys 21 are arranged at intervals along the length direction of the second plate body 19. Under the action of the second elastic member 20, the pulleys 21 are elastically in contact with the side wall of the slideway 701 in the support slide rail 2. The second elastic member 20 can be set as a spring. When the second plate body 19 is extruded by an external force, the second plate body 19 moves towards the first plate body 17 to achieve elastic contact between the sliding block 12 and the inner side wall of the support slide rail 2. By installing the pulleys 21 outside the second plate body 19, the stability of the sliding block 12 sliding along the support slide rail 2 is improved.

[0041] As Figure 5 and Figure 6 shown, the over-current and over-voltage protector 3 includes an over-current protection module 6, an over-voltage protection module 5, a switching component 7, and a connection circuit arranged in a housing 14. The switching component 7 is located between the over-current protection module 6 and the over-voltage protection module 5. At the same time, there are two groups of the over-current protection module 6, the over-voltage protection module 5, and the switching component 7 arranged along the height direction of the housing 14. Among them, the over-voltage protection module 5 includes a normally closed relay, a normally open relay, a voltage dividing circuit, and an MCU controller. The over-current protection module 6 includes a PTC thermistor, a bimetal temperature switch, a triode clamping circuit, and a control module. It also includes an auxiliary power supply for supplying power to the control module and the MCU controller.

[0042] As Figure 7 and Figure 8As shown in the figure, the switching component 7 includes a slideway 701, a partition 702 and a sub-space 703. The slideway 701 is arranged on the housing 14 between the overcurrent protection module 6 and the overvoltage protection module 5, and the slideway 701 is arranged in a circular ring shape. The partition 702 is fixedly connected in the slideway 701 and is evenly spaced along the length direction of the slideway 701 to divide the slideway 701 into several continuously arranged sub-spaces 703. A contact slider 35 is slidably connected in the sub-space 703 along the slideway 701. And, in order to ensure that the contact slider 35 is located at one end of the sub-space 703 in the initial position, a reset elastic member 22 is connected in the sub-space 703. One end of the reset elastic member 22 is connected to the contact slider 35, and the other end is connected to the partition 702. Among them, the reset elastic member 22 can be configured as a reset spring. A cover plate 23 is connected to the outer side wall of the slideway 701. The cover plate 23 is arranged in a circular shape corresponding to the slideway 701. A driving part 24 is installed on the side of the cover plate 23 close to the slideway 701. The output end of the driving part 24 is connected to a conversion rod 25. The end of the conversion rod 25 far from the driving part 24 is connected to an elastic contact block 2501. The driving part 24 is correspondingly arranged at the center position of the annular slideway 701. The driving part 24 drives the rotating rod to perform a circular motion around the center position of the slideway 701. So as to realize that the driving part 24 drives the conversion rod 25 to rotate, so that the elastic contact block 2501 drives the contact slider 35 to slide along the slideway 701 in a sub-space 703, and continue to move to another adjacent sub-space 703 after contacting the partition 702, and contact the contact slider 35 in another sub-space 703, so as to realize the intermittent electrical connection between the server power supply and the overvoltage protection module 5 and the overcurrent protection module 6 in turn.

[0043] Further, a contact groove 26 is formed in the contact slider 35, and the contact groove 26 is open on the side facing the elastic contact block 2501, which is convenient for the elastic contact block 2501 to enter the contact groove 26 and convenient for connecting the overcurrent protection module 6 or the overvoltage protection module 5.

[0044] In use, the driving part 24 drives the conversion rod 25 to rotate, so that the elastic contact block 2501 drives the contact slider 35 to slide along the slideway 701 in a sub-space 703. At this time, when the elastic contact block 2501 rotates, it can drive the contact slider 35 to squeeze the reset elastic member 22. During the squeezing process, the elastic contact block 2501 is always in contact with the contact slider 35 to make the corresponding protection module work properly at this time. When the contact slider 35 is pressed against the side wall of the partition plate 702, the rotation stops. According to the power supply state of the detection server of the detection circuit, if it is necessary to switch to another protection module, under the drive of the driving part 24, the elastic contact block 2501 continues to rotate. After finally disengaging from the contact slot 26, it enters the next sub-interval and contacts the contact slider 35 in this sub-interval, and then compresses the reset elastic member 22. After completion, the rotation stops. During the switching, under the action of the reset elastic member 22, the contact slider 35 can be made to approach the partition plate 702. When it is necessary to switch the protection module, the switching stroke can be effectively shortened, the switching efficiency can be improved, and it is convenient to switch the connection circuit to be connected to the overvoltage protection module 5 or the overcurrent protection module 6 according to the power supply state of the server, thereby solving the problem that the switching efficiency of the two protection modules is relatively low, and it is easy to cause overcurrent or overvoltage during the switching process of the power supply module, resulting in damage. In this way, it is beneficial to reduce the switching stroke and improve the switching efficiency.

[0045] In a specific embodiment, as Figure 9 shown, a fixed plate 27 is connected to the bottom of the support frame 33. A through hole 28 is opened on the bottom side of the fixed plate 27. An active pressure plate 29 is movably inserted through the through hole 28. An anti-slip pad 30 is fixedly connected to one end of the active pressure plate 29 close to the support slide rail 2. One end of the active pressure plate 29 is elastically connected to the fixed plate 27 through a third elastic member 31, and the other end extends out of the through hole 28 and is inserted into the slideway 701 of the support slide rail 2 and abuts against the bottom of the slideway 701; the third elastic member 31 is configured as a compression spring. After the active pressure plate 29 extends out, it is inserted into the slideway 701 on the support slide rail 2 through the anti-slip pad 30, and the support frame 33 is limited by friction, so as to realize the positioning of the overcurrent and overvoltage protector 3.

[0046] Further, the surface of the anti-slip pad 30 facing the support slide rail 2 is an inclined surface, and a connecting member is inserted through the bottom of one end of the fixed plate 27 close to the active pressure plate 29. By rotating the connecting member, when the end of the connecting member with a rubber pad contacts the support slide rail 2, the fixed plate 27 is fixed by friction, strengthening the fixing effect of the fixed plate 27 and making it more stable during use.

[0047] As Figure 9As described above, in order to facilitate the adjustment of the overcurrent and overvoltage protector 3 on the support frame 33, a handle 32 is fixedly connected to the bottom end of the movable pressure plate 29. After the movable pressure plate 29 is loosened through the handle 32, the support frame 33 and the overcurrent and overvoltage protector 3 therein can be driven to move.

[0048] It should be noted that the connecting parts in this embodiment include but are not limited to one or more of screws, the cooperation connection of screws and gourd holes, bolts, studs, rivets, pin shafts or connecting shafts.

[0049] Specific implementation process: When the server power protection device in this embodiment is working / being used, first, the overcurrent and overvoltage protector 3 is installed on the support frame 33, and the overcurrent and overvoltage protector 3 is limited by the multiple positioning plates 1301 of the support frame 33. Then, after adjusting the position of the overcurrent and overvoltage protector 3, it is tightened and fixed through the connecting parts. When the position of the overcurrent and overvoltage protector 3 needs to be adjusted, by loosening the connecting parts, the support frame 33 and the overcurrent and overvoltage protector 3 can slide on the support slide rail 2. During the sliding process, the handle 32 is pulled to make the anti-slip pad 30 away from the support slide rail 2, and then the support frame 33 slides vertically along the support slide rail 2 to realize the movement of the overcurrent and overvoltage protector 3 thereon. After moving to the specified position, the anti-slip pad 30 abuts against the support slide rail 2 under the action of the third elastic member 31 to limit the sliding of the support frame 33. At this time, it is convenient to adjust the position of the overcurrent and overvoltage protector 3 again. After the adjustment is completed, the connecting parts are tightened, and the overcurrent and overvoltage protector 3 is connected to the connection circuit through a wire to perform overcurrent and overvoltage protection on the power supply of the server. During the protection process, the circuit is detected by the detection module, and different protection modules are selected according to needs.

[0050] At the same time, the overcurrent and overvoltage protector 3 is provided with an overvoltage protection module 5, an overcurrent protection module 6 and a switching component 7. The switching component 7 is connected to the overcurrent and overvoltage protector 3 through a connection circuit to switch the connection circuit to be connected to the overvoltage protection module 5 or the overcurrent protection module 6 according to the power supply state of the server, so as to solve the problem that the switching efficiency of the two protection modules is relatively low, and it is easy to cause overcurrent or overvoltage during the switching process of the power supply module and thus damage.
