Description

Technical Field

[0001] This invention relates to the field of server hardware technology, specifically to a server hard drive backplane configuration structure. Background Technology

[0002] A server hard drive backplane, also known as a server hard drive bracket, is used to provide physical support for hard drives and connect the data transmission path between the hard drive and the motherboard.

[0003] Most existing hard drive backplates are drawer-type structures, requiring the backplate to be fully pulled out of the chassis when replacing a hard drive. The pull-out travel is typically 80-100mm to expose the hard drive connector. In high-density storage or compact servers, the limited operating space at the front of the chassis makes it difficult to fully pull out the backplate, resulting in difficulties in removing and placing the hard drive.

[0004] To address this issue, existing technology, such as the server disclosed in Chinese invention patent application CN109343668A, alters the angle between the hard drive loading / unloading port and the support plate by pivoting the hard drive module housing relative to the supporting chassis, thereby facilitating hard drive loading / unloading. However, this solution still has significant shortcomings in practical applications. First, in servers, hard drives are typically arranged vertically from top to bottom at intervals, and the tilt angle of a single hard drive is strictly limited by the distance between adjacent hard drives. To increase the tilt angle to obtain more operating space and achieve more convenient hard drive loading / unloading, the distance between adjacent hard drives must be increased, which requires reducing the hard drive density in the server. This is clearly disadvantageous in application scenarios that require high hard drive density within the server. Secondly, the limited rotation angle and limited front-to-back position change during the rotation of the hard drive module housing make it impossible to effectively expose the hard drive connection components installed at the rear of the server to the operator's field of vision at the front of the server. This makes it inconvenient for the operator to reach their hands and tools into the server from the front to inspect the hard drive connection components. This is obviously disadvantageous in application scenarios that pursue high front-to-back server density. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a server hard disk backplane configuration structure that can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a server hard drive backplane configuration structure, comprising two profiles arranged horizontally side by side within a server, the profiles extending along the front-rear direction of the server, and a slide bracket slidably mounted on one end of each profile along its length; a guide groove is provided on the opposite surface of each slide bracket, the guide groove extending horizontally along the sliding direction of the slide bracket; a support shaft is provided in each of the two guide grooves; the two support shafts extend to the space between the two slide brackets at their adjacent ends, and are jointly and fixedly connected to a hard drive clamp; an opening is provided at the front end of the hard drive clamp for the hard drive to enter and exit the hard drive clamp; Two support shafts extend from opposite ends to the corresponding carriage and profile respectively; an end ring is fixedly sleeved on the outer circumference of the support shaft located between the carriage and the profile, and the end ring is in contact with the carriage; a shift ring is also gapped on the outer circumference of the support shaft corresponding to one of the end rings; the shift ring is located between the end ring and the profile; the shift ring and the end ring are intermittently connected by transmission. A mounting base two is fixed along the length of the end of the profile corresponding to the transposition ring facing the slide. A guide groove two is provided on the rear side of the lower end of the mounting base two, and a guide groove three is provided on the front side of the lower end of the mounting base two. The guide groove two extends horizontally along the length of the mounting base two. One end of the guide groove three is connected to the guide groove two, and the other end extends forward and upward. A transposition post is fixed to the lower side of the end of the transposition ring furthest from the end ring; the transposition post cooperates with guide groove two and guide groove three.

[0007] Preferably, the sliding stroke of the carriage is less than or equal to half the length of the hard drive; the central axis of the support shaft is located behind the hard drive inside the hard drive clamp.

[0008] Preferably, an end plate is fixedly installed at the rear end of each profile, and an end box is fixedly installed at the front end of each profile.

[0009] Preferably, a rear baffle is fixedly connected to the opposite surfaces of the two carriages; the rear baffle is located behind the guide groove and can contact and cooperate with the end plate; the rear baffle is provided with a window for the hard disk connection components on the server to pass through.

[0010] Preferably, the end of the transposition ring facing the end ring contracts into a frustum, and an unlocking plate is provided below the frustum; the unlocking plate can move radially along the frustum and be inserted between the frustum and the end ring; the unlocking plate is slidably connected to the corresponding carriage.

[0011] Preferably, a pressure plate is embedded at one end of the mounting base two facing the shift ring; the pressure plate is slidably connected to the mounting base two along the axial direction of the shift ring; one end of the pressure plate abuts against the shift ring, and the other end is provided with a top block; the top block and the pressure plate form an inclined plane transmission connection.

[0012] Preferably, the top block is vertically slidably installed in the second mounting base, and a top compression spring is provided between the top block and the second mounting base, with the top compression spring in a pre-compressed state.

[0013] Preferably, an unlocking post is fixedly connected to one end of the unlocking plate along its length, and the unlocking post extends into the corresponding end box cavity; An adjusting shaft is rotatably mounted on the end box corresponding to the unlocking post. One end of the adjusting shaft extends to the front of the end box, and the other end extends into the inner cavity of the end box and is fixedly connected to an unlocking rod. The unlocking rod extends obliquely to the bottom of the unlocking post and is connected to the unlocking post in a transmission manner.

[0014] Preferably, the end box corresponding to the unlocking post has a movable slot for moving the unlocking post.

[0015] Compared with the prior art, the present invention provides a server hard disk backplane configuration structure, which has the following beneficial effects: 1. The front opening of the hard drive clamp is tilted downwards at 45°, allowing the hard drive to be pulled out of the clamp at an angle downwards or inserted into the clamp at an angle upwards or downwards. This tilt significantly increases the operating space when removing and placing the hard drive, making the operation more convenient and easier.

[0016] 2. When removing the hard drive, the horizontal distance from the front of the hard drive inside the hard drive clamp to the front of the end box is less than half the length of the hard drive. This greatly reduces the length of the operating space in front of the hard drive when removing it, making it suitable for use in environments with limited space in front of the server.

[0017] 3. When removing the hard drive, the length of the hard drive exposed on the server is greater than half the total length of the hard drive and also greater than the length of the hard drive located inside the server. Furthermore, the hard drive located inside the server is positioned in front of the central axis of the spindle. This ensures that the highest point of the hard drive inside the server can still be between the two hard drives above and below it, thus placing almost no additional requirements on the stacking spacing of adjacent hard drives. In other words, this invention can achieve convenient removal and placement while minimizing the impact on hard drive stacking density, effectively ensuring a high-density hard drive arrangement within the server.

[0018] 4. By adjusting the shaft, the teeth can be separated from the grooves, the transmission connection between the end ring and the shifting ring can be released, and the hard disk clamp can swing up and down 90° around the support shaft, effectively exposing the window and maximizing the space between the window and the hard disk clamp, thus facilitating the maintenance of the hard disk connection components installed in the window.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 12This invention discloses a server hard drive backplane configuration structure, comprising two profiles 1 arranged horizontally side-by-side within the server, the profiles 1 extending along the front-rear direction of the server. An end plate 21 is fixedly installed at the rear end of each profile 1, and an end box 15 is fixedly installed at the front end of each profile 1. It should be noted that the front-rear direction of the server is the same as the depth direction of the server.

[0023] Each of the two profiles 1 has a slide 2 at one end close to each other. The upper and lower ends of the slide 2 extend above and below the corresponding profile 1, respectively. Slide bars 202 are fixed to the slides 2 above and below the profile 1. The middle of the slide bar 202 is embedded in the profile 1 and can slide horizontally along the length of the profile 1. The slide bar 202 can slide to abut against the end box 15, thereby limiting the sliding stroke of the slide bar 2 and ensuring that the sliding stroke of the slide bar 2 is less than or equal to half the length of the hard disk 100.

[0024] A rear panel 203 is fixedly connected to the opposite sides of the two carriages 2 near the rear of the server. The rear panel 203 can contact and engage with the end plate 21 to prevent the carriages 2 from sliding off the server from the rear. The rear panel 203 is provided with a window 2031 for hard drive connection components on the server to pass through. Guide grooves 201 are provided on the opposite surfaces of the two slides 2. The guide grooves 201 are located in front of the rear baffle 203 and extend horizontally along the sliding direction of the slides 2. A base plate 204 is fixedly connected to the inner side of the two slides 2. The base plate 204 is located below the guide grooves 201, and a slot is provided at the center of the front end of the base plate 204. The slot serves as an operating space when loading and unloading the hard disk 100.

[0025] Each of the two guide slots 201 has a support shaft 4. The two support shafts 4 extend from one end close to each other to between the two carriages 2, and are jointly and fixedly connected to a hard disk clamp 3. The front end of the hard disk clamp 3 has an opening for the hard disk 100 to enter and exit the clamp 3. Specifically, the hard disk clamp 3 includes a clamping plate 31 and side plates 32; the clamping plate 31 has a U-shaped structure with its opening facing the front of the server, and its lower end extends to the front of its upper end; two side plates 32 are fixedly installed on the inner side of the clamping plate 31, and the space enclosed by the two side plates 32 and the clamping plate 31 is used to clamp the hard disk 100; the ends of the two side plates 32 that are far apart from each other are respectively fixedly connected to the two support shafts 4. It should be noted that the connection between the support shaft 4 and the side plate 32 is located at the rear end of the side plate 32, and the central axis of the support shaft 4 is located behind the hard disk 100 inside the hard disk clamp 3.

[0026] It should be noted that a front baffle 20 is also provided between the two carriages 2, and the front baffle 20 is located in front of the hard disk clamp 3. The front baffle 20 is used to stop the hard disk 100 in front of it and keep the hard disk 100 in the hard disk clamp 3.

[0027] Two fastening knobs are screwed onto the inner side of the front baffle 20, with the studs of the two fastening knobs facing the two carriages 2 respectively; the studs of the fastening knobs can pass through the corresponding carriages 2 and abut against the corresponding end box 15, so as to achieve relative stillness between the carriages 2, the front baffle 20 and the server.

[0028] Two limiting plates are fixed to the rear end of the front baffle 20. The two limiting plates can abut against the upper and lower surfaces of the hard disk 100 respectively to keep the hard disk 100 in a horizontal state.

[0029] It should be noted that before removing the hard drive 100 from the hard drive clamp 3, the front panel 20 needs to be removed by loosening the fastening knob.

[0030] Furthermore, the ends of the two support shafts 4, which are far apart from each other, extend to the space between the corresponding carriage 2 and the profile 1. An end ring 5 is fixedly fitted onto the outer circumference of the support shaft 4 located between the carriage 2 and the profile 1, and the end ring 5 contacts and engages with the carriage 2. The engagement of the two end rings 5 ​​with the two carriages 2 holds the hard disk clamp 3 between the two carriages 2, ensuring that the hard disk clamp 3 does not shift towards either carriage 2 during its movement.

[0031] One of the end rings 5 ​​has a linkage ring 6 fitted on its outer circumference. The linkage ring 6 and the end ring 5 are rotatably connected. A spring column 7 is fixedly installed on the slide 2 corresponding to the linkage ring 6; the spring column 7 is vertically set, and its moving end is pluggably installed on the linkage ring 6. Through the cooperation between the spring column 7 and the linkage ring 6, the slide 2 can move forward of the server along with the support shaft 4; When the slide bar 202 slides to abut against the end ring 5, as the support shaft 4 moves further forward of the server, it drives the linkage ring 6 to disengage from the spring column 7, allowing the slide 2 to move to the rear of the server to reset, thus achieving slot reset.

[0032] A shift ring 8 is also fitted on the outer circumferential surface of the support shaft 4 corresponding to the other end ring 5. The shift ring 8 is clearance-fitted with the support shaft 4, so that the shift ring 8 can move axially along the support shaft 4 and rotate circumferentially along the support shaft 4; the shift ring 8 is disposed between the end ring 5 and the profile 1.

[0033] The end of the transposition ring 8 facing the end ring 5 has multiple teeth spaced circumferentially along the support shaft 4; the end of the end ring 5 facing the transposition ring 8 has multiple tooth grooves; the multiple tooth grooves and multiple teeth engage. The intermittent transmission connection between the end ring 5 and the transposition ring 8 is achieved by whether the teeth and tooth grooves engage or not.

[0034] A transposition post 9 is fixed to the lower side of the end of the transposition ring 8 that is away from the end ring 5.

[0035] Furthermore, the middle of the two profiles 1 at their closest points is recessed. A mounting base 2 12 is fixedly installed in the recess of the profile 1 corresponding to the transposition ring 8. The mounting base 2 12 extends along the length of the profile 1. A guide groove 2 121 is provided on the rear side of the lower end of the mounting base 2 12, and a guide groove 3 122 is provided on the front side of the lower end of the mounting base 2 12. The guide groove 2 121 extends horizontally along the length of the mounting base 2 12. One end of the guide groove 3 122 is connected to the guide groove 2 121, and the other end extends forward and upward.

[0036] The transposition post 9 is matched with guide groove 2 121 and guide groove 3 122.

[0037] refer to Figure 10 The above technical solution is used as follows: Remove the front baffle 20 to move the hard disk 100 forward, which will cause the support shaft 4 to move in the guide groove 1 201, and cause the shifting column 9 to move along the guide groove 2 121, so that the slide bar 202 moves towards the end box 15. When the slider 202 abuts against the end box 15, the transposition post 9 is located at the intersection of the guide groove 2 121 and the guide groove 3 122; the front end of the hard disk 100 is exposed between the two end boxes 15, so that the horizontal distance between the front end of the hard disk 100 and the front end of the end box 15 is M, and M is less than half the length of the hard disk 100.

[0038] After the slide bar 202 abuts against the end box 15, as the support shaft 4 moves further forward of the server, the transposition post 9 moves along the guide groove 122, causing the lower end of the transposition ring 8 to swing upward and backward, and through the cooperation of the teeth and grooves, it causes the support shaft 4 to deflect, so that the front end of the hard disk clamp 3 and the hard disk 100 are further exposed between the two end boxes 15 and tilted downward into the slot. After the transposition post 9 moves to the end of the guide slot 122, the front end of the hard disk 100 tilts downward at an angle of 45°. The horizontal distance from the front end of the hard disk 100 to the front end of the end box 15 is N, which is greater than M and less than half the length of the hard disk 100.

[0039] exist Figure 10 In the diagram, the three shortest center lines represent the change in the horizontal position of the spindle 4 during the movement of the hard disk 100; the distance between the two second shortest center lines is the length of the hard disk 100; and the horizontal distances from the two third shortest center lines to the longest center line are M and N, respectively.

[0040] With the above configuration, the server hard disk backplane configuration structure of the present invention has the following significant effects when placing or removing the hard disk 100: First, the front opening of the hard drive clamp 3 is tilted downwards at 45°, allowing the hard drive 100 to be pulled out of the hard drive clamp 3 at an angle downwards, or inserted into the hard drive clamp 3 at an angle up and down. This tilting posture can significantly increase the operating space when removing and placing the hard drive 100, making the operation of removing and placing the hard drive 100 more convenient and easier.

[0041] Secondly, when removing the hard disk 100, the horizontal distance from the front end of the hard disk 100 inside the hard disk clamp 3 to the front end of the end box 15 is less than half the length of the hard disk 100. This greatly reduces the need for the length of the operating space in front of the hard disk 100 when removing the hard disk 100, making it suitable for use in environments with limited space in front of the server.

[0042] Finally, when removing the hard drive 100, the length of the hard drive 100 exposed on the server is greater than half the length of the hard drive 100 itself, and also greater than the length of the hard drive 100 located inside the server. Furthermore, the hard drive 100 located inside the server is positioned in front of the central axis of the spindle 4. This ensures that the highest point of the hard drive 100 inside the server remains between the two adjacent hard drives 100 within the server, thus placing almost no additional requirements on the stacking spacing of the adjacent hard drives (100). In other words, this invention can achieve convenient removal and placement while minimizing the impact on the stacking density of the hard drives 100, effectively ensuring a high-density hard drive arrangement within the server.

[0043] Furthermore, the transposition ring 8 retracts into a frustum at one end toward the end ring 5, and an unlocking plate 10 is provided below the frustum. The unlocking plate 10 can move radially along the frustum and be inserted between the frustum and the end ring 5 to separate the teeth from the tooth groove.

[0044] The surface of the unlocking plate 10 away from the truncated cone is slidably fitted with a mounting base 11, which is fixedly connected to the corresponding slide 2.

[0045] Furthermore, a pressure plate 13 is embedded at one end of the mounting base 12 facing the transposition ring 8. The pressure plate 13 is slidably connected to the mounting base 12 along the axial direction of the transposition ring 8. One end of the pressure plate 13 abuts against the transposition ring 8, and the other end is provided with a top block 14; the top block 14 and the pressure plate 13 form an inclined plane transmission connection; the top block 14 is vertically slidably installed in the mounting base 12, and a top pressure spring 141 is provided between the top block 14 and the mounting base 12. The top pressure spring 141 is in a pre-compressed state, and the rebound force of the top pressure spring 141 is used to drive the pressure plate 13 to move toward the transposition ring 8.

[0046] Furthermore, an unlocking post 101 is fixedly connected to one end of the unlocking plate 10 along its length, and the unlocking post 101 extends into the inner cavity of the corresponding end box 15.

[0047] The end box 15 corresponding to the unlocking post 101 has a movable slot for the unlocking post 101 to move.

[0048] An adjustment shaft 151 is rotatably mounted on the end box 15 corresponding to the unlocking post 101. One end of the adjustment shaft 151 extends to the front of the end box 15 and is fixedly connected to an adjustment knob 152. The other end of the adjustment shaft 151 extends into the inner cavity of the end box 15 and is fixedly connected to a linkage plate 153. An unlocking rod 154 is fixedly connected to the linkage plate 153. The unlocking rod 154 extends obliquely to the bottom of the unlocking post 101 and is connected to the unlocking post 101 in a transmission manner.

[0049] By rotating the adjustment knob 152 clockwise, the adjustment shaft 151 rotates, causing the linkage plate 153 and the unlocking rod 154 to rotate and move upward, which can push the unlocking post 101 upward, insert the unlocking plate 10 between the end ring 5 and the frustum, realize the separation of the teeth and the groove, release the transmission connection between the end ring 5 and the shift ring 8, and make the pressure plate 13 slide into the mounting base 12, compressing the top pressure spring 141.

[0050] When the adjustment knob 152 is turned counterclockwise, the top pressure spring 141 rebounds and pushes the truncated cone to the end ring 5, so that the teeth are engaged in the tooth groove, and the end ring 5 and the shift ring 8 are connected together again, so that the unlocking plate 10 moves and resets.

[0051] After the teeth separate from the groove, as the support shaft 4 moves along the guide groove 201, the support shaft 4 can be manually rotated to make the front end of the hard disk 100 swing up and down; and after the hard disk 100 is removed, the hard disk clamp 3 can swing up and down 90° around the support shaft 4, which facilitates the maintenance of the components on the server that are electrically connected to the hard disk 100 from the front of the server.

[0052] like Figure 11 and Figure 12 As shown, the hard disk clamp 3 rotates downward to a 90° position and is located in the slot of the base plate 204, effectively exposing the window 2031 and maximizing the space between the window 2031 and the hard disk clamp 3, thereby facilitating the maintenance of the hard disk connection components installed in the window 2031.

[0053] Furthermore, a lead screw 17 is provided above the truncated cone, and the lead screw 17 extends along the length direction of the profile 1; the rear end of the lead screw 17 is rotatably connected to the corresponding end plate 21, and the front end extends into the inner cavity of the corresponding end box 15 and is rotatably connected to the end box 15.

[0054] A transmission sleeve 171 is threaded onto the outer circumference of the lead screw 17. A transmission plate 16 is rotatably mounted on the outer circumference of the end ring 5 corresponding to the frustum. A transmission column 161 is fixed on the transmission plate 16 and is pluggably mounted onto the transmission sleeve 171.

[0055] A transmission gear 172 is fixed on a lead screw 17 located inside the end box 15. A gear shaft 18 is rotatably mounted inside the end box 15. The teeth of the gear shaft 18 mesh with the transmission gear 172. A pull rope 19 is wound around the outer circumference of the shaft portion of the gear shaft 18. Both ends of the pull rope 19 pass downward through the end box 15.

[0056] By pulling down both ends of the pull rope 19, the gear shaft 18 can be reciprocated, which in turn causes the transmission gear 172 and the lead screw 17 to reciprocate, thereby causing the transmission sleeve 171, transmission column 161 and transmission plate 16 to move back and forth, and thus the support shaft 4 to move back and forth.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
