Description

Technical Field

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

[0002] The hard disk backplane is a component used to connect the server motherboard and the hard disk, also known as the hard disk bracket. Its main function is to provide physical support for the hard disk and connect the data transmission path between the hard disk and the motherboard. At present, the hard disk backplane is mainly installed on the hard disk slot or fixed frame of the server chassis, which 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, which is used to provide power supply; the other is the data interface, which is used to connect the hard disk and the motherboard.

[0003] In a rack-mounted server, the hard disk backplane is usually designed in a rectangular shape and is provided in multiples. Each hard disk backplane is an independent unit. Its main task is to provide an interface for the hard disk and connect to the server's mainboard through a data cable or to the mainboard through an array card. Each of them independently handles the data transmission of the hard disk connected to it. When installing the hard disk backplane, you need 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 to the bracket. Make sure the backplane is installed firmly without shaking or loosening.

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

[0005] However, most of the current server hard disks need to be fixed with a large number of screws. When a hard disk fails, all the screws need to be removed with tools, which makes the removal of the hard disk backplane body cumbersome and difficult to quickly remove and replace, reducing the overall work efficiency. At the same time, the fixing effect of the hard disk backplane body is poor, making it easy to shake, and the interface is easy to loosen. Summary of the invention

[0006] To this end, the present invention provides a server hard disk backplane configuration structure to solve the problems that the existing hard disk backplane body is complicated to disassemble, cannot be quickly disassembled and replaced, and has a poor fixing effect on the hard disk backplane body.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] A server hard disk backplane configuration structure comprises a mounting side plate, a positioning plate and a fixing rod, a fixing frame is fixedly mounted in the middle of the mounting side plate, a hard disk backplane body is arranged outside the front end of the fixing frame, an adjusting rod is installed at the upper middle end of the fixing frame, and a transmission assembly located in the fixing frame is arranged outside the lower end of the adjusting rod;

[0009] A positioning plate is integrally 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 connecting plate is installed in the middle of the front end of the positioning plate;

[0010] A fixing rod is arranged at the front end of the transmission assembly, and the front end of the fixing rod extends into the positioning plate and contacts the first connecting plate.

[0011] Furthermore, the hard disk backplane body is connected to the positioning plate by plugging, and a hard disk interface is provided on the outer side of the hard disk backplane body, and a prefabricated groove is provided through the middle of the lower end of the hard disk backplane body.

[0012] Furthermore, the transmission assembly 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, the transmission rod is rotatably installed inside the fixed frame, and the gear located directly in front of the rack is fixedly installed on the outer side of the transmission rod.

[0013] Furthermore, a U-shaped transmission shaft is fixedly installed in the middle and both ends of the transmission rod, and the middle part of the U-shaped transmission shaft is connected to the rear end of the fixed rod. A prefabricated through groove is opened inside the rear end of the fixed rod, and the U-shaped transmission shaft is connected to the fixed rod in a sliding manner through the prefabricated through groove.

[0014] Furthermore, a limit bar is integrally fixedly installed on the outer side of the front end of the rack, and the rack and the limit bar are connected to the fixing frame in a sliding manner.

[0015] Furthermore, the fixing rod is connected to the hard disk backplane body by plugging.

[0016] Furthermore, the limiting assembly includes a second airbag, a second connecting plate, a connecting gasket, a mounting plate and a return spring. The second airbag is installed in the mounting cavity, and a second connecting plate is installed on the outer side of the rear end of the second airbag. The second airbag is connected to the connecting hose.

[0017] Furthermore, a connection gasket is attached to the rear surface of the second connection plate, and the connection gasket is in contact with the front end of the side of the hard disk backplane body, and 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, and a return spring is installed on the outer side of the rear end of the second connecting plate.

[0019] Furthermore, an installation cavity for installing a limiting component is opened inside the positioning plate, a first airbag is installed inside the front end of the positioning plate, and a first connecting plate is arranged on the outer side of the rear end of the first airbag, a connecting hose is arranged on the outer side of the first airbag, and a limiting component is arranged on the outer side of one 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 opposite direction, so that the U-shaped transmission shaft drives the fixing rod to move backward, which is convenient for pulling the fixing rod out of the hard disk backplane body, so that the fixing rod loses its fixing effect on the hard disk backplane body. At the same time, the fixing rod is disconnected from the first connecting plate, and the restoring spring in the stretched state recovers its deformation, driving the second connecting plate and the connecting gasket to move backward in the installation cavity. At this time, the second connecting plate exerts an extrusion effect on the second airbag, so that the gas in the second airbag flows into the first airbag through the connecting hose, thereby facilitating the first airbag and the first connecting plate to restore their original state, facilitating the subsequent fixed installation of the hard disk backplane body, thereby reducing the cumbersome effect of disassembling the hard disk backplane body, facilitating relatively fast 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 through 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, so that the volume of the second airbag increases, driving the second connecting plate and the connecting gasket to move backward, and at the same time stretching the reset spring. As the volume of the second airbag increases, the connecting gasket is tightly connected to the side front end of the hard disk backplane body under the action of the second airbag, thereby facilitating the improvement of the fixing effect of the hard disk backplane body during installation, and preventing the hard disk backplane body from shaking due to vibration or external force during transportation or operation, which makes the interface easy to loosen;

[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 sets of fixing rods move forward under the action of the U-shaped transmission shaft and are respectively inserted into the through holes opened in the hard disk backplane body, so that the hard disk backplane body plays a fixing role, thereby improving the installation effect of the hard disk backplane body.

[0034] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0035] like Figures 1 to 7 As shown, 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 panel 1, and a positioning plate 3 is integrally fixedly installed on the outer front end of the fixing frame 2, a hard disk backplane body 4 is arranged on the outer 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 opened through the middle of the lower end of the hard disk backplane body 4.

[0036] Among them, fixing bolts 22 are installed through the upper and lower sides of the rear end of the installation side panel 1, which makes it convenient to fix the installation side panel 1 and the fixing frame 2 to the specified position in the server through the fixing bolts 22. The plate-like structures connected to the installation side panel 1 arranged on both sides of the middle part of the fixing frame 2 are staggered 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 in a plug-in manner, which is convenient for limiting and supporting the two sides of the hard disk backplane body 4 through multiple sets of positioning plates 3, thereby improving the firmness of the installation of the hard disk backplane body 4; and the prefabricated groove 23 is used for wiring to prevent the hard disk backplane body 4 from affecting the overall wiring inside the server.

[0038] An adjusting rod 6 is installed at the upper middle end of the fixing frame 2, and a transmission assembly located in the fixing frame 2 is arranged on the outer side of the lower end of the adjusting rod 6. The transmission assembly 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. The 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 is connected to the fixing frame 2 in a threaded manner, so that the height of the rack 7 can be adjusted 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 in the fixing frame 2; a limit bar 24 is integrally fixedly installed on the outer side of the front end of the rack 7, and the rack 7 and the limit bar 24 are both connected to the fixing frame 2 in a sliding manner. When the rack 7 moves, the limit bar 24 moves synchronously with it, which is convenient for improving the stability of the movement of the rack 7 in the fixing frame 2.

[0040] At the same time, a fixing rod 11 is provided at the front end of the transmission assembly, and a prefabricated through groove 12 is penetrated inside the rear end of the fixing rod 11, and a U-shaped transmission shaft 10 is fixedly installed in the middle and both ends of the transmission rod 8, and the middle part of the U-shaped transmission shaft 10 is connected to the rear end of the fixing rod 11, and 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 plays an installation role for the U-shaped transmission shaft 10, which facilitates the transmission rod 8 to drive the U-shaped transmission shaft 10 to rotate synchronously in the fixing frame 2 while rotating, so as to facilitate the fixing rod 11 to move at the front end of the fixing frame 2 through the rotation of the U-shaped transmission shaft 10, thereby facilitating the subsequent fixation 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 provided 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 by plugging, 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 plays an installation role for the first connecting plate 13, which makes it convenient for the first connecting plate 13 to contact with the fixing rod 11 when the fixing rod 11 fixes the first airbag 14, so that the fixing rod 11 produces a forward squeezing force on the first connecting plate 13, causing the first connecting plate 13 to move forward in the positioning plate 3, thereby squeezing the first airbag 14.

[0043] A connecting hose 15 is provided on the outer side of the first airbag 14, and a limiting assembly is provided 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 assembly is provided inside the positioning plate 3. The limiting assembly 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 connected to the connecting hose 15. After the first airbag 14 is squeezed, the gas inside it can flow into the second airbag 16 through the connecting hose 15. At the same time, a connecting gasket 18 is pasted on the rear surface of the second connecting plate 17. The connecting gasket 18 is in contact with the side front end of the hard disk backplane body 4, which is convenient for installing the connecting gasket 18 through the second connecting plate 17. Therefore, the connecting gasket 18 can be tightly connected with the side front end of the hard disk backplane body 4 under the action of the second airbag 16, thereby improving the fixing effect of the hard disk backplane body 4, avoiding the hard disk backplane body 4 from shaking due to vibration or external force during transportation or operation, and making the interface easy to loosen.

[0045] The second connecting plate 17 is connected to the positioning plate 3 in a sliding manner. A mounting 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 mounting plate 19 is fixedly installed in the mounting cavity 21, which plays a good installation role for the second airbag 16. At the same time, the reset spring 20 plays an auxiliary supporting role for the second connecting plate 17, which facilitates the adjustment of the position of the second connecting plate 17 and the connecting gasket 18 under the joint action of the reset spring 20 and the second airbag 16, thereby determining the connection status of the connecting gasket 18 and the hard disk backplane body 4.

[0047] How it works

[0048] First, place the installation side plate 1 and the fixing frame 2 stably at the designated position in the server, and then fix the installation side plate 1 with the fixing bolts 22. After fixing, insert the hard disk backplane body 4 from top to bottom to the front outer side 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, so that the through hole opened inside the side of the hard disk backplane body 4 is aligned with the fixing rod 11.

[0049] The adjusting rod 6 is rotated to make the adjusting rod 6 threadedly connected with the fixing frame 2. At this time, the adjusting rod 6 rotates in the middle of the upper end of the rack 7 through the bearing. As the adjusting rod 6 rotates, the lower end of the adjusting rod 6 moves upward in the fixing frame 2, thereby driving the rack 7 and the limit bar 24 to move upward synchronously. The rack 7 is meshed with the gear 9 while moving, thereby driving the gear 9, the transmission rod 8 and the multiple sets of U-shaped transmission shafts 10 to rotate synchronously clockwise inside the fixing frame 2, so that the U-shaped transmission shaft 10 is connected with the corresponding fixing rod 11 through the prefabricated through groove 12 in a sliding manner, and then the multiple sets of fixing rods 11 move forward under the action of the U-shaped transmission shaft 10, and are respectively inserted into the through holes opened in the hard disk backplane body 4, so that the hard disk backplane body 4 plays a fixing role, and the installation effect of the hard disk backplane body 4 is improved.

[0050] As the fixing rod 11 moves, the front end of the fixing rod 11 penetrates the hard disk backplane body 4 and contacts 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, so that the volume of the second airbag 16 increases, driving the second connecting plate 17 and the connecting gasket 18 to move backward, and at the same time, the reset spring 20 is stretched. As the volume of the second airbag 16 increases, the connecting gasket 18 is tightly connected to the side front end of the hard disk backplane body 4 under the action of the second airbag 16, so as to improve the fixing effect of the hard disk backplane body 4 during installation, and avoid the hard disk backplane body 4 from shaking due to vibration or external force during transportation or operation, so that the interface is easy to loosen. After the installation is completed, insert the hard disk into the outside of the hard disk interface 5, and connect the power interface and data interface of the hard disk backplane body 4 to the server motherboard or power backplane.

[0051] When the hard disk backplane body 4 needs to be disassembled, the above steps can be reversed. It is only necessary to rotate the adjusting rod 6 in the reverse direction so that the adjusting rod 6 can drive 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 rack 7, thereby making the U-shaped transmission shaft 10 drive the fixing rod 11 to move backward, making it easy to pull the fixing rod 11 out of the hard disk backplane body 4, so that the fixing rod 11 loses 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, and the restoring spring 20 in the stretched state recovers its 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 exerts an extrusion 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, thereby facilitating the first airbag 14 and the first connecting plate 13 to restore their original state, facilitating the subsequent fixed installation of the hard disk backplane body 4, thereby reducing the cumbersome effect of disassembling the hard disk backplane body 4, facilitating relatively quick 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 may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
