Description

Technical Field

[0001] This application relates to the field of server technology, and in particular to a test device and test method for server chassis sag. Background Technology

[0002] As server architectures become increasingly complex, the layout of various boards, hard drives, and other components within the chassis becomes denser, resulting in a greater load on the chassis.

[0003] After assembly, the server chassis will sag and deform under the weight of various circuit boards, hard drives, and other components. This sag and deformation is a major reason why servers cannot be easily pulled out from within the same rack. Therefore, server designers aim to minimize this sag and deformation. However, due to the wide variety of server architectures, it is generally impossible to accurately predict the amount of chassis sag during the design phase.

[0004] Therefore, how to provide a test device for server chassis sag is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

During this process, distance measurement data from at least three points is first read to form a reference plane in the data processing computer. Then, distance measurement data from the remaining points is read to obtain the server chassis sag data, which is then stored in the data processing computer. Subsequently, an upward arching force is provided to the server chassis by the adjustment component.

The upward arching force provided by the adjustment component generates an upward arching amount on the server chassis. Through repeated testing and iterative optimization, compensation for the server chassis sag can be achieved.

[0053] Based on the above structural and process descriptions, it can be seen that the server chassis recess measurement testing equipment has at least the following beneficial effects: the server chassis recess measurement testing equipment solves the problem of testing and adjusting server chassis recess, has the characteristics of simple operation, and reduces the iterative optimization cost of server chassis testing and adjustment.

[0065] Server chassis 01. Detailed Implementation

[0066] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0067] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0068] As explained in the background section, server chassis will sag under gravitational loads. In real-world business applications, servers are often housed in high-density racks with minimal spacing between them. Therefore, it is crucial to carefully control the sag of the server chassis; otherwise, the sag of upper-level servers will encroach on the space of lower-level servers, making it difficult to remove or retract them. Consequently, the design of server sag is a critical issue that must be properly addressed in server design and manufacturing. This problem is increasingly attracting the attention of server design companies.

[0069] In recent years, server designers have often used testing instruments to measure the deformation of the server chassis (with counterweights replacing individual components) under gravity after the server chassis is manufactured, thereby understanding the deformation of the server chassis when subjected to gravity.

[0070] Practice has shown that resolving the issue of excessive server chassis sag primarily relies on adding pre-deformation to the chassis. This pre-deformation creates an upward arch in the chassis before it is subjected to gravity, thus counteracting deformation under gravity. Because server chassis have complex shapes and house various types of components, the spatial distribution of sag deformation is complex. To address this, designers need to apply different amounts of arching to different parts of the chassis and conduct repeated sag tests until the deformation at the bottom of the chassis is reduced to within the design requirements. During this optimization process, designers must repeatedly test, add arching, test, add arching, and test again. This iterative process is extremely time-consuming and labor-intensive. Testing and adding pre-arching often involve two separate pieces of equipment, resulting in additional material handling costs.

[0071] Therefore, the existing server chassis testing and adjustment iteration optimization process has the following main drawbacks: (1) Due to the complexity of the chassis and the wide variety of components inside, determining the chassis camber often requires multiple iterations to find the optimal value; (2) When adjusting the chassis camber, the chassis needs to be removed from the sag test device and moved to the chassis camber device. After adjusting the chassis camber, the chassis is then moved to the chassis sag test device; (3) Multiple optimization iterations are required to find the optimal value of the chassis sag. Therefore, adjusting the chassis camber requires a total of 3 steps: test-camber-test, making the entire iteration process time-consuming and labor-intensive.

[0072] In view of the aforementioned prior art, this application provides a test device for server chassis sag, please refer to... Figure 1 , Figure 1 A schematic diagram of the structure of the server chassis sag test device provided in the embodiments of this application.

[0073] like Figure 1 As shown, a test device for server chassis sag mainly includes a test base 1, a detection component 2, and an adjustment component 3.

[0074] In this embodiment, the test base 1 is the foundation of the entire testing equipment, and all other components are mounted on the test base 1. The rigidity of the test base 1 meets the usage requirements; for example, cast iron is an acceptable material choice for the test base 1. During use, in addition to mounting all other components on the test base 1, the server chassis 01 is placed on the test base 1, and according to the initially determined server architecture scheme, counterweights are placed on the server chassis 01 to simulate the sinking of the server chassis 01 during actual use and the amount of sinking.

[0075] The detection component 2 is located above the server chassis 01. The detection component 2 is the detection part of the entire testing equipment. The detection component 2 detects the sinking detection area of ​​the server chassis 01 to obtain the sinking data of the server chassis 01.

[0076] The adjustment component 3 is located below the server chassis 01. The adjustment component 3 is the adjustment part of the entire test equipment. The adjustment component 3 provides an upward arching force to the server chassis 01 based on the sinking data in order to compensate for the sinking of the server chassis 01, such as the cancellation of sinking and upward arching when fully compensated.

[0077] In the process of using the server chassis sag testing equipment, firstly, the server chassis 01 is placed in the test base 1 of the testing equipment. According to the server configuration requirements, counterweights representing various server components are configured and placed at the corresponding positions on the server chassis 01. Then, the sag detection area of ​​the server chassis 01 is detected by the detection component 2. The sag detection area should cover the placement position of the counterweights. During this process, distance measurement data from at least three points are read and a baseline is formed in the data processing computer. The system first measures the plane, then reads the distance measurement data of the remaining points to obtain the sinking data of the server chassis 01 and stores it in the data processing computer. Subsequently, the system adjusts the component 3 to provide an upward arching force to the server chassis 01. The upward arching force provided by the adjustment component 3 to the server chassis 01 should be calculated based on the sinking data of the server chassis 01. Then, the upward arching force provided by the adjustment component 3 to the server chassis 01 generates an upward arching amount on the server chassis 01. Through repeated testing and iterative optimization, the sinking amount of the server chassis 01 can be compensated.

[0078] Based on the above structural and process descriptions, it can be seen that the server chassis sag measurement testing equipment has at least the following beneficial effects: the server chassis sag measurement testing equipment solves the problem of testing and adjusting the server chassis 01 sag measurement, has the characteristics of simple operation, and reduces the iterative optimization cost of testing and adjusting server chassis 01.

[0079] By using this testing equipment, the traditional steps of "testing the recess - removing the chassis - adding an arch to the chassis - removing the chassis - testing the recess" are no longer necessary during the optimization and iteration process. Instead, the chassis recess testing and adjustment can be completed on a single device. Compared with existing solutions, this equipment can significantly save testing and adjustment time and reduce chassis relocation costs. Furthermore, the device has a simple structure, can be mass-produced, is easy to install, and has low operating costs.

[0080] In some embodiments, the testing device further includes a controller connected to the detection component 2, the controller being used to receive subsidence data, and the controller being connected to the adjustment component 3, the controller being used to implement:

[0081] After receiving the first sinking data, the control adjustment component 3 acts on the server chassis 01 and generates an upward arch corresponding to the first sinking data. The system then receives the second sinking data and compares it with the standard sinking value. If the second sinking data is less than or equal to the standard sinking value, the test and adjustment are complete. If the second sinking data is greater than the standard sinking value, the control adjustment component 3 acts on the server chassis 01 again and generates an upward arch corresponding to the second sinking data. This process is repeated until the Nth sinking data is less than or equal to the standard sinking value, at which point the iteration stops; where N is a positive integer.

[0082] In this embodiment, the optimal value of the upward arch of the server chassis 01 can be determined through multiple optimization iterations. That is, based on the measured downward arch of the server chassis 01, the upward arch of the server chassis 01 is continuously adjusted to counteract the downward arch of the server chassis 01.

[0083] The iterative process is as follows: (1) Place the server chassis 01 without the added camber on the test equipment, and then place the counterweight representing the weight of each component in the server chassis 01 inside the server chassis 01. Collect the camber of the server chassis 01 through the test equipment; (2) If the camber of the server chassis 01 is less than the value required by the standard, the iteration stops. If it does not meet the requirements, add camber to the server chassis 01; (3) First, select the part with the largest camber exceeding the specified value and record its position. Record its camber and position according to the value of the camber. According to the above data records, add the corresponding camber to the server chassis 01 through the test equipment. Continue to collect the camber of the server chassis 01 through the test equipment and check whether its camber meets the requirements; (4) Iterate in this way until the camber of each part of the server chassis 01 meets the standard requirements.

[0084] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the probe module provided in an embodiment of this application.

[0085] In some embodiments, the detection component 2 includes a probe holder 201 and a probe module 202.

[0086] like Figure 2As shown, probe brackets 201 are installed on both sides of the test base 1, facing each other and extending along the height direction of the test base 1. The upper end of the probe bracket 201 can fix the probe module 202. The two ends of the probe module 202 are installed on the probe brackets 201 on the corresponding sides of the test base 1. The probe module 202 is equipped with a ranging probe 20201, and the detection direction of the ranging probe 20201 is vertically set towards the server chassis 01.

[0087] Optionally, the ranging probe 20201 is a laser ranging probe. Its ranging principle is to obtain the ranging data between the ranging probe 20201 and the server chassis 01 based on laser ranging, and then obtain the sinking amount of the server chassis 01 based on the ranging data.

[0088] It should be noted that the subsidence can be calculated by the difference between the distance measurement data of the ranging probe 20201 before and after two measurements, or by first determining the reference plane and then calculating it based on the difference between the distance measurement data and the reference plane. Both of these methods should fall within the scope of this embodiment.

[0089] Please continue to refer to this. Figure 2 In some embodiments, the detection component 2 includes a plurality of probe modules 202, which are spaced apart along the length of the test base 1.

[0090] In this embodiment, multiple probe modules 202 in the detection component 2 detect different sag areas of the server chassis 01, thereby obtaining distance measurement data of the detection points in the sag detection area. The chassis sag is calculated based on the distance measurement data, and the upward arch is calculated based on the chassis sag. Then, the adjustment component 3 provides upward arching force to different positions of the server chassis 01, so that the sag and upward arch at the same position are matched, thus expanding the testing and adjustment range for chassis sag on the server chassis 01.

[0091] Based on this, the detection component 2 includes multiple sets of ranging probes 20201. The number of sets of ranging probes 20201 corresponds to the number of probe modules 202. Multiple ranging probes 20201 are set on each probe module 202, and the multiple ranging probes 20201 are spaced apart in the width direction of the test base 1.

[0092] In this embodiment, a reference plane can be formed using ranging data from multiple ranging probes 20201, for example, using ranging data from at least three ranging probes 20201, and these three ranging probes 20201 are located on at least two probe modules 202. Figure 2As shown, markers A and B represent two ranging probes 20201 on the first probe module 202, and marker C represents one ranging probe 20201 on another probe module 202. Following the principle that three points define a plane, the ranging data from the three ranging probes 20201 form a reference plane. Based on this, the difference between the ranging data from the remaining ranging probes 20201 and the reference plane can be used to obtain the subsidence data of the server chassis 01. The calculation formula is as follows: Chassis subsidence = Distance measured by the ranging probe - Distance from the ranging probe to the reference plane.

[0093] Please refer to Figure 3 and Figure 6 , Figure 3 This is a schematic diagram of the structure of the adjustment component provided in an embodiment of this application. Figure 6 This is a schematic diagram of the structure of the cam provided in an embodiment of this application.

[0094] In some embodiments, the adjustment component 3 includes a first drive 301, a rotating shaft 302, a cam 303, and a push rod 304.

[0095] The first driving member 301 is used to output rotational power. Optionally, the first driving member 301 is a stepper motor. The rotating shaft 302 is connected to the first driving member 301 and is used to rotate around the rotation axis 302 line under the drive of the first driving member 301. The cam 303 is disposed on the rotating shaft 302 and is fixed relative to the rotating shaft 302. The cam 303 is used to rotate under the drive of the rotating shaft 302. The outer surface of the cam 303 is provided with at least a first curved surface 30301 and a second curved surface 30302, and the second curved surface 30302 protrudes from the first curved surface 30301. The push rod 304 abuts against the cam 303 and is used to push upward and provide an upward arching force to the server chassis 01 when the contact position with the cam 303 changes from the first curved surface 30301 to the second curved surface 30302.

[0096] Please continue to refer to this. Figure 3 In some embodiments, the adjustment component 3 includes a plurality of rotating shafts 302, which are spaced apart along the length of the test base 1. The rotation of the plurality of rotating shafts 302 is independent of each other, so that the push rods 304 on the plurality of rotating shafts 302 provide an upward arching force to different areas of the server chassis 01.

[0097] In this embodiment, by adjusting the multiple rotating shafts 302 in the component 3 and the cams 303 and push rods 304 on the rotating shafts 302, an upward arching force is provided to different areas of the server chassis 01, so that the server chassis 01 generates an upward arching amount at the same position that matches the sinking amount, thereby expanding the testing and adjustment range for the chassis sinking amount on the server chassis 01.

[0098] Based on this, the adjustment component 3 includes multiple sets of cams 303. The number of sets of cams 303 corresponds to the number of rotating shafts 302. Multiple cams 303 are provided on each rotating shaft 302. The multiple cams 303 are spaced apart in the width direction of the test base 1. The multiple cams 303 rotate synchronously on the same rotating shaft 302.

[0099] In this embodiment, the principle of chassis recess adjustment is as follows: the first driving component 301 drives the rotating shaft 302 to rotate. Driven by the rotating shaft 302, the cam 303 pushes up the push rod 304, causing the push rod 304 to lift the bottom of the server chassis 01 from below, thereby providing an upward arching force to the server chassis 01 and causing the server chassis 01 to arch upward. The rotation angle of the rotating shaft 302 is controlled by the chassis recess data stored in the data processing computer. That is, the upward arching is calculated based on the chassis recess, and then the lift of the adjusting push rod 304 is obtained from the upward arching. Finally, the angle that the cam 303 needs to rotate through is calculated through the rotation angle-lift curve of the cam 303. This angle is transmitted to the control system of the first driving component 301, which issues a control signal to make the rotating shaft 302 rotate through the corresponding angle.

[0100] Furthermore, to improve adjustment efficiency, the data processing computer can calculate the upward arching amount at different positions based on the stored chassis recess amount, allowing different rotating axes 302 to rotate through different angles simultaneously. After the rotating axis 302 has rotated through the corresponding angle, the push rod 304 causes the server chassis 01 to generate a certain upward arching amount, which will cancel out the chassis recess amount. Theoretically, only one adjustment is needed, but this can also be achieved through an iterative optimization process.

[0101] If it is an iterative optimization process, after the first round of adjustments is completed, the chassis recess can be retested according to the aforementioned testing process. If the recess at the bottom of the chassis meets the standard requirements, the adjustment process can be completed. Otherwise, the next round of testing and adjustment can be carried out according to the aforementioned process.

[0102] Please refer to Figure 4 , Figure 4 This is a schematic diagram of the push rod provided in an embodiment of this application.

[0103] like Figure 4 As shown, the push rod 304 adopts a design that is wider at the bottom and narrower at the top. The lower part is the force-receiving part 30401, and the upper part is the force-applying part 30402. The purpose is that the narrower design at the top is conducive to more precise application of the upward arch, and the wider design at the bottom is conducive to more even distribution of force from the cam 303.

[0104] Please refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of the limiting plate provided in an embodiment of this application.

[0105] like Figure 5 As shown, the limiting plate 306 has mounting holes 30602 at both ends. The limiting plate 306 is fixed to the test base 1 through the mounting holes 30602. The limiting plate 306 also has vertically penetrating limiting holes 30601. The limiting holes 30601 are distributed along the length of the limiting plate 306. The limiting holes 30601 allow the push rod 304 to pass through and restrict the push rod 304 from sliding in the vertical direction.

[0106] Based on this, the push rod 304 is further provided with a limiting part 30403 between the force receiving part 30401 and the force applying part 30402. The diameter of the limiting part 30403 is larger than that of the force receiving part 30401 and smaller than that of the limiting hole 30601. When the limiting part 30403 abuts against the bottom of the limiting plate 306, the push rod 304 has the maximum lifting height.

[0107] In addition, the rotating shaft 302 adopts a design with unequal lengths of optical shafts on both sides. The purpose is that the longer end can extend out of the test base 1 and be connected to the first drive member 301 through the coupling 305.

[0108] Please refer to Figure 7 , Figure 7 This is a schematic diagram of the structure of the first shifting component provided in an embodiment of this application.

[0109] In one specific embodiment, in order to further improve the use effect of the above-mentioned testing equipment and enable the detection component 2 and the adjustment component 3 to have the effect of movable position, the testing equipment also includes a displacement component. The displacement component is disposed on the testing base 1. The detection component 2 and the adjustment component 3 are installed on the testing base 1 through the displacement component. The displacement component is used to adjust the position of the detection component 2 and the adjustment component 3 in the length direction of the testing base 1. The displacement component includes a first displacement component 4 connected to the detection component 2 and a second displacement component connected to the adjustment component 3.

[0110] It should be noted that there are various ways to implement the first shifting component 4 and the second shifting component, including but not limited to cylinders, linear electric cylinders, etc., which should also fall within the scope of this embodiment.

[0111] In some embodiments, the first shifting component 4 includes a shifting track 401, a shifting slider 402, a support plate 403, a second driving member 404, and a pitch-changing mechanism 405.

[0112] like Figure 7As shown, a shift track 401 is mounted on the test base 1, extending along the length of the test base 1. A shift slider 402 is mounted on the shift track 401 and can slide along the shift track 401. A support plate 403 is mounted on the shift slider 402 and can move along the shift track 401 via the shift slider 402. A second drive member 404 is mounted on the test base 1, and its actuating end is connected to the support plate 403. The second drive member 404 provides the power for the movement of the support plate 403. A pitch-changing mechanism 405 is mounted on the support plate 403 and is connected to the detection assembly 2. The pitch-changing mechanism 405 outputs linear power and adjusts the distance between multiple probe modules 202.

[0113] In this embodiment, the movement position of the detection component 2 on the test base 1 can be adjusted by the drive of the second drive component 404. On the one hand, by adjusting the movement position of the detection component 2 on the test base 1, the detection component 2 can be moved away when the server chassis 01 is placed into the test base 1, improving the convenience of use. On the other hand, when testing and adjusting the server chassis 01 placed in the test base 1, by adjusting the movement position of the detection component 2 on the test base 1, the area detected by the detection component 2 can be changed, so that the detection component 2 can detect the server chassis 01 with a smaller detection range per test and multiple tests, reducing the construction volume of the detection component 2, improving the applicability of the test, and meeting more testing conditions.

[0114] In addition, because the variable distance mechanism 405 can adjust the distance between multiple probe modules 202, the density of the area detected by the detection component 2 can be adjusted, thereby meeting more testing conditions.

[0115] Please continue to refer to this. Figure 7 The pitch mechanism 405 includes a support base 40501, a bidirectional lead screw 40502, a third drive member 40503, a first nut seat 40504, a center seat 40505, and a second nut seat 40506.

[0116] In this embodiment, the support base 40501 is mounted on the support plate 403. A bidirectional lead screw 40502 is mounted on the support base 40501 and can rotate relative to the support base 40501 around its rotation axis 302. A third drive member 40503 is mounted on the support plate 403, and its actuating end is connected to the bidirectional lead screw 40502. The third drive member 40503 outputs rotational power and drives the bidirectional lead screw 40502 to rotate. A first nut seat 40504 is mounted on the first section of the bidirectional lead screw 40502 and engages with its positive thread. The first nut seat 40504 is connected to the probe bracket 201 on which the first probe module 202 is mounted. The center seat 40505 is installed in the middle of the bidirectional lead screw 40502 and mates with the unthreaded section of the bidirectional lead screw 40502. The center seat 40505 is connected to the probe bracket 201 on which the second probe module 202 is installed. The second nut seat 40506 is installed in the second section of the bidirectional lead screw 40502 and mates with the reverse thread of the bidirectional lead screw 40502. The second nut seat 40506 is connected to the probe bracket 201 on which the third probe module 202 is installed.

[0117] When the second driving component 404 is activated, the detection component 2 adjusts its position along the length of the test base 1; when the third driving component 40503 is activated, the probe module 202 in the detection component 2 adjusts its spacing along the length of the test base 1.

[0118] Please refer to Figure 8 , Figure 8 This is a schematic diagram of the transposition component provided in an embodiment of this application.

[0119] like Figure 8 As shown, the testing equipment also includes a rotation component 5, which is installed on the test base 1. The rotation component 5 is used to adjust the placement angle (rotation angle in the horizontal plane) of the server chassis 01 in the test base 1. By adjusting the placement angle of the server chassis 01 in the test base 1, the downward test direction of the server chassis 01 can be matched with the downward adjustment direction of the adjustment component 3.

[0120] For example, when the server chassis 01 is placed in the test base 1 at the first placement angle, the multiple probe modules 202 in the detection component 2 test the server chassis 01 in a fixed position, corresponding to the first type of sinking test of the server chassis 01. The multiple rotating shafts 302, cams 303, and push rods 304 in the adjustment component 3 adjust the server chassis 01 in a fixed position, corresponding to the first type of sinking adjustment of the server chassis 01. When the server chassis 01 is rotated by a certain angle and placed in the test base 1 at the second placement angle, although the multiple probe modules 202 in the detection component 2 and the multiple rotating shafts 302, cams 303, and push rods 304 in the adjustment component 3 are still in fixed positions, the detection component 2 will correspond to the second type of sinking test of the server chassis 01, and the adjustment component 3 will correspond to the second type of sinking adjustment of the server chassis 01, thus realizing multiple testing and adjustment methods for the server chassis 01.

[0121] Please continue to refer to this. Figure 8 The indexing assembly 5 includes a fourth drive 501, a fifth drive 502, and a tray 503.

[0122] The fourth drive unit 501 is mounted on the test base 1 and is used to output linear power. The fifth drive unit 502 is mounted on the actuating end of the fourth drive unit 501 and is used to output rotational power. The tray 503 is mounted on the actuating end of the fifth drive unit 502 and is used to lift and place the server chassis 01 under the drive of the fourth drive unit 501 and to adjust the orientation angle of the lifted server chassis 01 under the drive of the fifth drive unit 502.

[0123] This application also provides a method for testing server chassis recess, using the aforementioned testing equipment, and the testing method includes:

[0124] S1. Place the server chassis 01 in the test base 1 of the test equipment, and place the counterweights corresponding to the configuration requirements in the corresponding positions of the server chassis 01 according to the server configuration requirements.

[0125] S2. Use detection component 2 to detect the sinking detection area of ​​server chassis 01. First, read the distance measurement data of the corresponding points using at least three distance measuring probes 20201, for example... Figure 2 The markers A, B, and C shown form a reference plane in the data processing computer. Then, the ranging data of the corresponding points of the remaining ranging probe 20201 are read to obtain the sinking data of the server chassis 01 and store it in the data processing computer.

[0126] S3. Based on the sinking data of the server chassis 01 measured in the previous step, the data processing computer calculates the upward arching force data that the adjustment component 3 should provide to the server chassis 01, obtains the rotation angle data of the rotating shaft 302, and makes the rotating shaft 302 rotate through the corresponding angle. The cam 303 on the rotating shaft 302 acts on the push rod 304, and the push rod 304 applies an upward arching force to the server chassis 01.

[0127] S4. Repeat step S2 to detect the sinking amount of server chassis 01, and compare the sinking amount data of server chassis 01 with the standard value of sinking amount of server chassis 01 to determine whether to continue to adjust the sinking amount.

[0128] If a next iteration is required, repeat the testing and adjustment steps S2 to S4 above.

[0129] After testing and adjustments are completed, remove server chassis 01 and record the results.
