Description

Technical Field

[0001] The utility model belongs to the technical field of server SAG measurement, and particularly relates to a weight block structure of a server SAG measurement main board module and a server module. Background Art

[0002] With the development of servers, the server architecture design is becoming more and more extreme. The server configuration is compact, the overall weight of the server is getting heavier, and the gaps between components are getting smaller and smaller, resulting in more and more problems of overall SAG (sinking or sagging) of the server. The overall SAG value of the server should neither be too high nor too low. If the SAG value is too low, it will cause installation interference between components and make installation difficult. If the SAG value is too high, it means that the overall machine sinks too much, and interference is likely to occur between the overall machines when placed in the cabinet.

[0003] At present, the measurement of the overall SAG value of the server is usually carried out in the chassis factory. Generally, the chassis is pre-arched first, then weight blocks are placed in the chassis to simulate the weight of the components in the chassis, and finally the overall SAG value of the server is measured on the measuring instrument. According to the measured SAG value, the arch amount of the chassis is adjusted, and this process is repeated until the SAG value meets the requirements, and then the corresponding arch amount of the chassis at this time is determined as the design value control for future use. In this process, whether the weight and placement position of the weight block are consistent with the actual components directly affect the accuracy of the SAG measurement. However, the weight blocks currently used in the chassis factory usually only have a few weights of certain specifications, and the weight blocks have uniform quality, single form, and fixed centroid, making it difficult to simulate the actual weight distribution and centroid position in the chassis, thus unable to ensure the accuracy of the overall SAG value measurement of the server, and further affecting the accuracy of the design value of the chassis arch amount. Summary of the Utility Model

[0004] In order to solve the problem that the traditional weight block has uniform quality, single form, and fixed centroid, making it difficult to simulate the actual weight distribution and centroid position in the chassis, thus unable to ensure the accuracy of the overall SAG value measurement of the server, and further affecting the accuracy of the design value of the chassis arch amount, the utility model provides a weight block structure of a server SAG measurement main board module and a server module.

[0005] On the one hand, the utility model is realized by the following technical solutions:

[0006] A server SAG measurement motherboard module counterweight structure includes several first counterweights in the shape of rectangular plates, several second counterweights, and several third counterweights. On one adjacent side of the first counterweight, there are several positioning posts, and on the other adjacent side, there are positioning holes that can be inserted and positioned with the positioning posts. On the upper side of the first counterweight, there are several slide rails. On the lower side of the second counterweight, there are chutes that can be slidably matched with the slide rails. On the upper side and the left and right sides of the second counterweight, there are slideways that are in the same direction as the chutes. On one side of the third counterweight, there are sliders that can be slidably matched with the slideways.

[0007] A further improvement of the present utility model is that chamfers are provided at the ends of the positioning posts and the positioning holes.

[0008] A further improvement of the present utility model is that the cross-sections of the slide rails and the chutes are in a matching trapezoidal structure.

[0009] A further improvement of the present utility model is that a chamfer is provided at the end of the chute.

[0010] A further improvement of the present utility model is that the slideway is in an arc surface structure, and its included angle is greater than 180 degrees.

[0011] A further improvement of the present utility model is that a chamfer is provided at the end of the slider.

[0012] A further improvement of the present utility model is that a first size scale is provided on the first counterweight along the direction of the slide rail.

[0013] A further improvement of the present utility model is that a second size scale is provided on the second counterweight along the direction of the slideway.

[0014] A further improvement of the present utility model is that the number of sliders is two.

[0015] On the other hand, the present utility model is realized through the following technical solutions:

[0016] A server module includes a chassis, and a hard disk module, a fan module, a power supply module, and the server SAG measurement motherboard module counterweight structure are installed on the chassis.

[0017] From the above technical solutions, it can be seen that the beneficial effects of the present utility model are:

[0018] The weight block structure of the server SAG measurement main board module can be directly placed inside the chassis. For the simulation of the main board module, several first weight blocks are inserted and positioned through corresponding positioning posts and positioning holes, and are flexibly combined to simulate the main board (weight and size). A second weight block (matched with the chute) is slidably installed on the slide rail of the first weight block, and the front and rear positions of the second weight block are slidably adjusted. Third weight blocks of different weights are selectively installed on the upper side, left and right sides of the second weight block (the slider is slidably matched with the slideway), and the precise adjustment of the center of mass can be flexibly realized. Thus, by selectively combining different weights of the third weight blocks with the second weight block, the true simulation (position, center of mass and weight) of the CPU, radiator and memory on the main board is realized, so as to ensure the accuracy of the server SAG measurement and the accuracy of the designed value of the chassis camber. The overall structure is simple and easy to implement. The weight blocks can be flexibly assembled and moved and adjusted to realize the accuracy of the simulation of different main board modules. It has strong versatility and a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] To make the objectives, features, and advantages of the present utility model more obvious and understandable, the following will clearly and completely describe the technical solutions in the present utility model with reference to the accompanying drawings in the specific embodiments. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this patent.

[0027] As Figure 2-5 shown, the present utility model discloses a weight block structure for a server SAG measurement main board module, which includes a plurality of first weight blocks 1 in the shape of rectangular plates, a plurality of second weight blocks 2, and a plurality of third weight blocks 3; a plurality of (4) positioning posts 12 are arrayed on an adjacent side (right side and rear side) of the first weight block 1, and positioning holes 13 (arrayed 4) capable of being inserted and positioned with the positioning posts 12 are provided on the other adjacent side (left side and front side). A plurality of front-to-back sliding rails 11 are arrayed on the upper side of the left and right of the first weight block 1; the second weight block 2 has a cuboid structure, and a sliding groove 21 capable of slidingly cooperating with the sliding rail 11 is provided on its lower side, and sliding grooves 22 in the same direction as the sliding groove 21 are respectively provided on its upper side and left and right sides; the third weight block 3 has a cuboid structure, and a slider 31 capable of slidingly cooperating with the sliding groove 22 is provided on one of its side surfaces.

[0028] The weight block structure of the server SAG measurement main board module can be directly placed in the chassis 4. For the main board module simulation, a plurality of first weight blocks 1 are inserted and positioned through the corresponding positioning posts 12 and positioning holes 13, and are flexibly combined to simulate the main board (weight, size). The second weight block 2 (matched with the sliding groove 21) is slidably installed on the sliding rail 11 on the first weight block 1, and the front-to-back position of the second weight block 2 is slidably adjusted. Different weights of the third weight block 3 are selectively installed (the slider 31 slidingly cooperates with the sliding groove 22) on the upper side and left and right sides of the second weight block 2, and the precise adjustment of the center of mass can be flexibly realized. Thus, by selectively combining different weights of the third weight block 3 with the second weight block 2, the true simulation (position, center of mass, and weight) of the CPU, radiator, and memory on the main board is realized, thereby ensuring the accuracy of the server SAG measurement and the accuracy of the design value of the chassis camber. The overall structure is simple, easy to implement, the weight blocks can be flexibly assembled and moved and adjusted, the accuracy of different main board module simulations can be realized, and it has strong versatility and a wide range of applications.

[0029] To ensure the accuracy of the simulation, the second weight block 2 and the third weight block 3 can be designed with multiple weights.

[0030] The front and rear surfaces of the second weight block 2 are square, and its side surfaces (up and down, left and right) are 20 mm long.

[0031] Among them, to ensure the convenience of the insertion and fitting of the positioning post 12 and the positioning hole 13, chamfers are provided at the ends of both the positioning post 12 and the positioning hole 13, which play a guiding role.

[0032] As Figure 2 , 3 shown, the cross-sections of the slide rail 11 and the chute 21 are in a trapezoidal structure that matches each other. Through the trapezoidal engagement and sliding guidance, reliable engagement and guiding sliding adjustment of the second counterweight 2 with the slide rail 11 on the first counterweight 1 can be achieved.

[0033] Among them, to ensure the convenience of the engagement between the chute 21 and the slide rail 11, a chamfer is provided at the end of the chute 21, which plays a guiding role.

[0034] As Figure 1-2 shown, the length of the slide rail 11 is the same as the front and back length of the first counterweight 1, that is, the slide rail 11 is arranged throughout. When the first counterweights 1 are docked front and back, it can ensure that the corresponding slide rails 11 can also be docked tightly, avoiding large gaps that may cause the second counterweight 2 (chute 21) to slide and jam.

[0035] Among them, as Figure 3-4 shown, the slideway 22 has an arc surface structure, and its included angle is greater than 180 degrees, preferably 300 degrees. The slider 31 has an arc surface columnar structure that matches the slideway 22. When the two sliders 31 are engaged with the two slideways 22, the third counterweight 3 fits against the corresponding side surface of the second counterweight 2 to ensure the reliability of the engagement.

[0036] Furthermore, to ensure the convenience of the insertion of the slider 31 into the slideway 22, a chamfer is provided at the end of the slider 31, which plays a guiding role.

[0037] Among them, on the first counterweight 1 (the upper left and right edges), a first size scale is provided along the direction of the slide rail 11. The adjustment position of the second counterweight 2 can be visually displayed, realizing the accuracy of the adjustment.

[0038] Furthermore, on the second counterweight 2 (at the upper left and right edges), a second size scale is provided along the direction of the slideway 22. The front and back adjustment positions of the third counterweight 3 on the second counterweight 2 can be visually displayed, realizing the accuracy of the adjustment.

[0039] Among them, the number of the sliders 31 is two, and the number of the slideways 22 on each side of the second counterweight 2 is two, which not only ensures the reliability of the engagement between the third counterweight 3 and the second counterweight 2, but also ensures the convenience of the insertion of the slider 31 into the slideway 22.

[0040] As Figure 1As shown in the figure, the present utility model also discloses a server module, which includes a chassis. A hard disk module, a fan module, a power supply module and the server SAG measurement main board module counterweight structure are installed on the chassis. The whole server mainly consists of a hard disk module, a fan module, a power supply module, a main board module, etc. Among them, the hard disk, fan and power supply are selected components and are common components in different servers. Therefore, the counterweight of this part can be replaced by physical objects. The main board module is generally the module with the heaviest weight and the largest size in the whole server, and the main boards of different servers are designed differently according to requirements. Since most of the main boards are newly developed and the price of the main board module is relatively high, if the main board module is provided to the chassis factory for SAG testing for different main boards, this approach is too costly and prone to material waste. Therefore, the server SAG measurement main board module counterweight structure is used to simulate the main board module.

[0041] For the server SAG measurement main board module counterweight structure and the server module, the server SAG measurement main board module counterweight structure can be directly placed in the chassis 4. For simulating the main board module, several first counterweights 1 are inserted and positioned through corresponding positioning posts 12 and positioning holes 13, and are flexibly combined to simulate the main board (weight and size). A second counterweight 2 (matched with the chute 21) is slidably installed on the slide rail 11 of the first counterweight 1, and the front and rear positions of the second counterweight 2 are slidably adjusted. Different weights of third counterweights 3 are selectively installed on the upper side and the left and right sides of the second counterweight 2 (the slide block 31 is slidably matched with the slideway 22), and the precise adjustment of the center of mass can be flexibly realized. Thus, by selectively combining different weights of third counterweights 3 with the second counterweight 2, the true simulation (position, center of mass and weight) of the CPU, radiator and memory on the main board is realized, so as to ensure the accuracy of the server SAG measurement and the accuracy of the designed value of the chassis upward arch amount. The overall structure is simple, easy to implement, the counterweights can be flexibly assembled and moved and adjusted, the accuracy of simulating different main board modules is realized, the universality is strong, and the applicable range is wide.
