Description

Technical Field

[0001] The present invention relates to the technical field of hard disk backplanes, and particularly to a configuration structure of a server hard disk backplane. Background Art

[0002] A hard disk backplane is a component used to connect a server motherboard and hard disks, also known as a hard disk carrier. Its main function is to provide physical support for the hard disks and connect the data transmission path between the hard disks and the motherboard. Currently, hard disk backplanes are mainly installed in the hard disk slots or fixing brackets of a server chassis and can accommodate multiple hard disks. There are usually two important interfaces on the hard disk backplane: one is the power interface of the hard disk for providing power supply; the other is the data interface for connecting the hard disk and the motherboard.

[0003] In a rack-mounted server, hard disk backplanes are usually designed in a rectangular shape and there are multiple of them. Each hard disk backplane is an independent unit. Their main task is to provide interfaces for the hard disks and connect to the server motherboard through data cables or connect to the motherboard through an array card, and independently process the data transmission of the hard disks connected thereto. When installing the hard disk backplane, it is necessary to first find the position of the backplane bracket, then align the hard disk backplane with the backplane bracket, and use multiple screws to fix the backplane on the bracket. Ensure that the backplane is firmly installed without shaking or loosening.

[0004] When a hard disk backplane has a hardware failure, such as interface damage, circuit board failure, or failure to correctly identify the connected hard disk, it needs to be quickly replaced to ensure the normal operation of the server. These failures may cause problems such as data read / write errors, the hard disk not being recognized by the system, or a decrease in data transmission speed. At the same time, if the performance of the existing hard disk backplane cannot meet the requirements of server data processing, for example, the data transmission rate of the backplane is lower than that of the hard disk, resulting in a data transmission bottleneck, it may be necessary to replace it with a higher-performance hard disk backplane to improve the overall performance of the server.

[0005] However, currently, when most server hard disks are fixed, a relatively large number of screws need to be locked for fixation. When a certain hard disk fails, it is necessary to use tools to remove all the screws, making the disassembly of the hard disk backplane body relatively cumbersome, unable to quickly disassemble and replace the hard disk backplane body, and reducing the overall work efficiency. At the same time, the fixing effect on the hard disk backplane body is poor, making it prone to shaking, and thus the interface is prone to loosening. Summary of the Invention

[0006] Therefore, the present invention provides a configuration structure of a server hard disk backplane to solve the problems that the disassembly of the hard disk backplane body is relatively cumbersome, unable to quickly disassemble and replace the hard disk backplane body, and at the same time, the fixing effect on the hard disk backplane body is poor.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A server hard disk backplane configuration structure includes a mounting side plate, a positioning plate, and a fixing rod. A fixing frame is fixedly installed in the middle of the mounting side plate. A hard disk backplane body is arranged on the outer side of the front end of the fixing frame. An adjusting rod is installed at the upper end of the middle of the fixing frame, and a transmission component is arranged on the outer side of the lower end of the adjusting rod and located inside the fixing frame;

[0009] The positioning plate is integrally and fixedly installed on the outer side of the front end of the fixing frame. A limiting component is installed on the inner side of the front end of the positioning plate, and a first connection plate is installed in the middle of the front end of the positioning plate;

[0010] The front end of the transmission component is provided with a fixing rod, and the front end of the fixing rod extends into the positioning plate and contacts the first connection plate.

[0011] Further, the hard disk backplane body is connected to the positioning plate in a plug-in manner, and a hard disk interface is arranged on the outer side of the hard disk backplane body. A prefabricated groove is penetrated and opened in the middle of the lower end of the hard disk backplane body.

[0012] Further, the transmission component includes a rack, a transmission rod, a gear, and a U-shaped transmission shaft. The rack is installed on the outer side of the lower end of the adjusting rod through a bearing. A transmission rod is rotatably installed inside the fixing frame, and a gear located directly in front of the rack is fixedly installed on the outer side of the transmission rod.

[0013] Further, U-shaped transmission shafts are fixedly installed in the middle and at both ends of the transmission rod, and the middle of the U-shaped transmission shaft is connected to the rear end of the fixing rod. A prefabricated through groove is penetrated inside the rear end of the fixing rod, and the U-shaped transmission shaft is connected to the fixing rod in a sliding manner through the prefabricated through groove.

[0014] Further, a limiting strip is integrally and fixedly installed on the outer side of the front end of the rack, and both the rack and the limiting strip are connected to the fixing frame in a sliding manner.

[0015] Further, the fixing rod is connected to the hard disk backplane body in a plug-in manner.

[0016] Further, the limiting component includes a second airbag, a second connection plate, a connection gasket, a mounting plate, and a return spring. The second airbag is installed in the mounting cavity, and a second connection plate is installed on the outer side of the rear end of the second airbag. The second airbag is communicated with a connection hose.

[0017] Further, a connection gasket is adhesively arranged on the rear surface of the second connection plate, and the connection gasket contacts the front side of the edge of the hard disk backplane body. The second connection plate is connected to the positioning plate in a sliding manner.

[0018] Furthermore, a mounting plate is installed on the outer side of the front end of the second airbag, and the mounting plate is fixedly installed in the mounting cavity. A return spring is installed on the outer side of the rear end of the second connecting plate.

[0019] Furthermore, a mounting cavity for installing a limiting component is formed inside the positioning plate. A first airbag is installed inside the front end of the positioning plate. A first connecting plate is arranged on the outer side of the rear end of the first airbag. A connecting hose is communicated with the outer side of the first airbag. A limiting component is arranged on the outer side of the end of the connecting hose away from the first airbag.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. By adjusting the height of the rack through the adjusting rod, the transmission rod, the gear and the U-shaped transmission shaft are driven to rotate in the reverse direction, so that the U-shaped transmission shaft drives the fixing rod to move backward, facilitating the extraction of the fixing rod from the hard disk backplane body, and making the fixing rod lose the fixing effect on the hard disk backplane body. At the same time, the connection between the fixing rod and the first connecting plate is released. At this time, the return spring in the stretched state restores its deformation, driving the second connecting plate and the connecting gasket to move backward in the mounting cavity. At this time, the second connecting plate exerts a squeezing effect on the second airbag, so that the gas in the second airbag flows into the first airbag through the connecting hose, thus facilitating driving the first airbag and the first connecting plate to return to their original states, facilitating subsequent fixing and installation of the hard disk backplane body, and further reducing the cumbersome effect of disassembling the hard disk backplane body, facilitating relatively rapid disassembly and replacement of the hard disk backplane body, and improving the overall installation work efficiency.

[0022] 2. Through the movement of the fixing rod, the front end of the fixing rod penetrates and inserts into the hard disk backplane body and contacts the first connecting plate, and exerts a squeezing force on the first connecting plate. At this time, the gas inside the first airbag flows into the second airbag through the connecting hose, making the volume of the second airbag increase, driving the second connecting plate and the connecting gasket to move backward, and at the same time stretching the return spring. As the volume of the second airbag increases, the connecting gasket is tightly connected to the front end of the side of the hard disk backplane body under the action of the second airbag, thus facilitating improving the fixing effect during the installation of the hard disk backplane body, and avoiding the hard disk backplane body from shaking due to vibration or external force during transportation or operation, and making the interface prone to looseness.

[0023] 3. The U-shaped transmission shaft is connected to the corresponding fixing rod in a sliding manner through a prefabricated through groove, so that multiple groups of fixing rods move forward under the action of the U-shaped transmission shaft and are respectively inserted into through holes formed in the hard disk backplane body, thereby playing a fixing role on the hard disk backplane body and improving the installation effect on the hard disk backplane body.

[0034] The following further details the present application with reference to the drawings through specific embodiments.

[0035] As shown Figures 1 to 7 in the figure, a server hard disk backplane configuration structure in an embodiment of the present invention includes a fixing frame 2 fixedly installed in the middle of an installation side plate 1, and a positioning plate 3 integrally and fixedly installed on the outer side of the front end of the fixing frame 2. A hard disk backplane body 4 is arranged on the outer side of the front end of the fixing frame 2, a hard disk interface 5 is arranged on the outer side of the hard disk backplane body 4, and a prefabricated groove 23 is penetrated and opened in the middle of the lower end of the hard disk backplane body 4.

[0036] Among them, fixing bolts 22 are penetrated and installed inside the upper and lower sides of the rear end of the installation side plate 1, which is convenient to fixedly install the installation side plate 1 and the fixing frame 2 at a specified position in the server through the fixing bolts 22. The plate-shaped structures connecting the fixing frame 2 on both sides of the middle part are arranged in a staggered manner with the position of the hard disk interface 5, which can not only avoid affecting the normal use of the hard disk backplane body 4 and the hard disk interface 5, but also make full use of the internal space of the server and improve the installation strength of the hard disk backplane body 4.

[0037] At the same time, the hard disk backplane body 4 and the positioning plate 3 are connected by plugging, which is convenient to limit and support both sides of the hard disk backplane body 4 through multiple groups of positioning plates 3, and is convenient to improve the firmness of the installation of the hard disk backplane body 4; and the prefabricated groove 23 is used for wiring to prevent the phenomenon that the hard disk backplane body 4 affects the overall wiring inside the server.

[0038] An adjusting rod 6 is installed at the upper end of the middle part of the fixing frame 2, and a transmission component is arranged on the outer side of the lower end of the adjusting rod 6 and located inside the fixing frame 2. The transmission component includes a rack 7, a transmission rod 8, a gear 9 and a U-shaped transmission shaft 10. The rack 7 is installed on the outer side of the lower end of the adjusting rod 6 through a bearing, and a transmission rod 8 is rotatably installed inside the fixing frame 2, and a gear 9 located directly in front of the rack 7 is fixedly installed on the outer side of the transmission rod 8.

[0039] Among them, the adjusting rod 6 and the fixing frame 2 are connected by a thread, which is convenient to adjust the height of the rack 7 by rotating the adjusting rod 6, so that the rack 7 can be meshed with the gear 9 when moving, thereby driving the transmission rod 8 to rotate inside the fixing frame 2; a limiting strip 24 is integrally and fixedly installed on the outer side of the front end of the rack 7, and both the rack 7 and the limiting strip 24 are connected to the fixing frame 2 by sliding. The limiting strip 24 moves synchronously with the rack 7 when the rack 7 moves, which is convenient to improve the smoothness of the movement of the rack 7 inside the fixing frame 2.

[0040] Meanwhile, a fixing rod 11 is arranged at the front end of the transmission assembly, and a prefabricated through groove 12 is formed in the rear end of the fixing rod 11 in a penetrating manner. U-shaped transmission shafts 10 are fixedly installed in the middle and at both ends of the transmission rod 8, and the middle of the U-shaped transmission shaft 10 is connected to the rear end of the fixing rod 11. The U-shaped transmission shaft 10 is connected to the fixing rod 11 in a sliding manner through the prefabricated through groove 12. The transmission rod 8 serves to install the U-shaped transmission shaft 10, facilitating the simultaneous rotation of the transmission rod 8 to drive the U-shaped transmission shaft 10 to rotate synchronously within the fixing frame 2, thereby facilitating the rotation of the U-shaped transmission shaft 10 to drive the fixing rod 11 to move at the front end of the fixing frame 2, and further facilitating the subsequent fixing of the hard disk backplane body 4.

[0041] A first airbag 14 is installed inside the front end of the positioning plate 3, and a first connecting plate 13 is arranged on the outer side of the rear end of the first airbag 14. The fixing rod 11 is connected to the hard disk backplane body 4 in a plug-in manner, and the front end of the fixing rod 11 extends into the positioning plate 3 and contacts the first connecting plate 13.

[0042] Among them, the first airbag 14 serves to install the first connecting plate 13, facilitating the contact between the first connecting plate 13 and the fixing rod 11 when the fixing rod 11 fixes the first airbag 14, so that the fixing rod 11 generates a forward extrusion force on the first connecting plate 13, causing the first connecting plate 13 to move forward within the positioning plate 3, thereby squeezing the first airbag 14.

[0043] A connecting hose 15 is communicated with the outer side of the first airbag 14, and a limiting component is arranged on the outer side of one end of the connecting hose 15 away from the first airbag 14. An installation cavity 21 for installing the limiting component is formed inside the positioning plate 3. The limiting component includes a second airbag 16, a second connecting plate 17, a connecting gasket 18, a mounting plate 19, and a return spring 20. The second airbag 16 is installed in the installation cavity 21, and a second connecting plate 17 is installed on the outer side of the rear end of the second airbag 16.

[0044] Among them, the second airbag 16 is communicated with the connecting hose 15, and the gas inside the first airbag 14 can flow into the second airbag 16 through the connecting hose 15 after the first airbag 14 is squeezed. At the same time, a connecting gasket 18 is adhesively arranged on the rear surface of the second connecting plate 17, and the connecting gasket 18 contacts the front side edge of the hard disk backplane body 4, facilitating the installation of the connecting gasket 18 through the second connecting plate 17, so that the connecting gasket 18 can be tightly connected to the front side edge of the hard disk backplane body 4 under the action of the second airbag 16, thereby improving the fixing effect on the hard disk backplane body 4 and preventing the hard disk backplane body 4 from shaking due to vibration or external force during transportation or operation, which may cause loosening at the interface.

[0045] The second connecting plate 17 is connected to the positioning plate 3 in a sliding manner. An installation plate 19 is installed on the outer side of the front end of the second airbag 16, and a return spring 20 is installed on the outer side of the rear end of the second connecting plate 17.

[0046] Among them, the installation plate 19 is fixedly installed in the installation cavity 21, which plays a good role in installing the second airbag 16. At the same time, the return spring 20 plays an auxiliary supporting role for the second connecting plate 17, facilitating the adjustment of the positions of the second connecting plate 17 and the connecting gasket 18 under the combined action of the return spring 20 and the second airbag 16, so as to determine the connection state between the connecting gasket 18 and the hard disk backplane body 4.

[0047] Working principle

[0048] First, stably place the installation side plate 1 and the fixing frame 2 at the designated position in the server, and then fix the installation side plate 1 through the fixing bolts 22. After fixing, insert the hard disk backplane body 4 from top to bottom to the outer side of the front end of the fixing frame 2. At this time, the side of the hard disk backplane body 4 is located inside the positioning plate 3 and slides with the positioning plate 3 until the bottom end, so that the through holes formed through the inner side of the hard disk backplane body 4 are aligned with the fixing rods 11.

[0049] Rotate the adjusting rod 6 so that the adjusting rod 6 is threadedly connected to the fixing frame 2. At this time, the adjusting rod 6 rotates through the bearing in the middle of the upper end of the rack 7. As the adjusting rod 6 rotates, the lower end of the adjusting rod 6 moves upward inside the fixing frame 2, thereby driving the rack 7 and the limiting strip 24 to move upward synchronously. While moving, the rack 7 is meshed with the gear 9, thereby driving the gear 9, the transmission rod 8 and multiple U-shaped transmission shafts 10 to rotate synchronously clockwise inside the fixing frame 2, so that the U-shaped transmission shafts 10 are connected to the corresponding fixing rods 11 in a sliding manner through the prefabricated through grooves 12. Furthermore, multiple fixing rods 11 move forward under the action of the U-shaped transmission shafts 10 and are respectively inserted into the through holes formed in the hard disk backplane body 4, thereby playing a fixing role for the hard disk backplane body 4 and improving the installation effect of the hard disk backplane body 4.

[0050] As the fixing rod 11 moves, the front end of the fixing rod 11 penetrates through the hard disk backplane body 4 and comes into contact with the first connecting plate 13, and generates a squeezing force on the first connecting plate 13. At this time, the gas inside the first airbag 14 flows into the second airbag 16 through the connecting hose 15, causing the volume of the second airbag 16 to increase, driving the second connecting plate 17 and the connecting gasket 18 to move backward, and at the same time stretching the return spring 20. As the volume of the second airbag 16 increases, the connecting gasket 18 is tightly connected to the front side of the edge of the hard disk backplane body 4 under the action of the second airbag 16, so as to facilitate improving the fixing effect during the installation of the hard disk backplane body 4, and avoid the hard disk backplane body 4 from shaking due to vibration or external force during transportation or operation, making the interface prone to looseness. After the installation is completed, insert the hard disk outside the hard disk interface 5, and at the same time connect the power interface and data interface of the hard disk backplane body 4 to the server motherboard or the power backplane.

[0051] When it is necessary to disassemble the hard disk backplane body 4, just operate in the reverse order of the above steps. Just rotate the adjusting rod 6 in the reverse direction, so that the adjusting rod 6 drives the transmission rod 8, the gear 9 and the U-shaped transmission shaft 10 to rotate in the reverse direction by adjusting the height of the adjusting rack 7, so that the U-shaped transmission shaft 10 drives the fixing rod 11 to move backward, facilitating the extraction of the fixing rod 11 from the hard disk backplane body 4, and making the fixing rod 11 lose its fixing effect on the hard disk backplane body 4. At the same time, the connection between the fixing rod 11 and the first connecting plate 13 is released. At this time, the stretched return spring 20 resumes deformation, driving the second connecting plate 17 and the connecting gasket 18 to move backward in the installation cavity 21. At this time, the second connecting plate 17 generates a squeezing effect on the second airbag 16, causing the gas in the second airbag 16 to flow into the first airbag 14 through the connecting hose 15, so as to facilitate driving the first airbag 14 and the first connecting plate 13 to return to their original states, facilitating subsequent fixing and installation of the hard disk backplane body 4, and thereby reducing the cumbersome effect of disassembling the hard disk backplane body 4, facilitating relatively rapid disassembly and replacement of the hard disk backplane body 4, and improving the overall installation work efficiency.

[0052] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written out should also be considered to be within the scope recorded in this specification.
