Description

Technical Field

[0001] The present application relates to the technical field of test tools, and particularly relates to a test fixture and a server backplane test device. Background Art

[0002] With the development of information technology, blade servers are widely used in scenarios such as data centers, enterprise applications, and cloud computing platforms due to their advantages of compact structure, low energy consumption, and strong scalability. As a component connecting each blade server, the backplane is responsible for tasks such as data communication, power distribution, and signal transmission, and its performance directly affects the operation stability of the whole machine and the data interaction efficiency. Therefore, before the delivery of the whole server, it is necessary to test the electrical connection status, power supply capacity, and communication channels of the backplane.

[0003] In related technologies, for backplane testing, multiple components such as the main board, power module, cooling fan, network connection module, and management control module usually need to be installed into the server rack in sequence. After the backplane to be tested is installed, the detection is carried out through overall power-on operation to verify the working status and compatibility of the backplane in terms of power supply, connection, and communication. Since this testing method depends on the completion of the whole machine assembly, the testing process is cumbersome, the operation cycle is long, and when the testing fails or the backplane needs to be replaced, it is also necessary to repeat the disassembly and assembly operations of multiple components, which affects the backplane testing efficiency. Based on this, there is an urgent need for a test fixture to solve the technical problem of low operation efficiency in server testing in related technologies. Summary of the Invention

[0004] The present application provides a test fixture and a server backplane test device to at least solve the problem of low operation efficiency in server testing in related technologies.

[0005] The present application provides a test fixture for docking a first module and a second module of a server, including: a test platform and at least one locking component; wherein,

[0006] The first module is slidably installed on the test platform, and approaches the second module along a preset sliding direction and docks with the second module;

[0007] The locking component includes a transmission member, a rotating member, and a locking mechanism in contact with the rotating member. The transmission member is installed on the outer side wall of the first module, and the rotating member is rotatably connected to the outer side wall of the second module;

[0008] The transmission member is meshed with the rotating member, and through the locking mechanism, the rotating member rotates unidirectionally along the direction in which the first module approaches the second module and maintains the docking state of the first module and the second module.

[0009] The present application also provides a server backplane test device, including a computer module, a connection device module, and the above-mentioned test fixture;

[0010] The connection device module is provided with a backplane installation area, and the server backplane is installed in the connection device module through the backplane installation area;

[0011] The computer module is docked with the server backplane;

[0012] Among them, the computer module is the first module, and the connection device module is the second module.

[0013] Through the present application, the first module is slidably installed with the test platform, so that the first module can move along a preset sliding direction to the position of the second module. Without the need to disassemble the first module and the second module as a whole, the quick docking of the first module and the second module can be realized, thereby reducing the operation time consumed by frequent disassembly and assembly of the modules and shortening the time required for test preparation and disassembly. At the same time, by setting a locking component including a transmission member, a rotating member and a locking mechanism, during the process of the first module sliding to the docking position, the transmission member and the rotating member are meshed and driven, and the rotating member is unidirectionally locked by the locking mechanism at the end of the sliding, automatically maintaining the docking state of the first module and the second module, without the need to perform a manual locking operation separately, simplifying the test preparation process and reducing the connection abnormality caused by loosening or displacement during the test. The structural setting of the present application realizes the automatic linkage of the sliding movement and locking process of the first module. Therefore, the problem of low test operation efficiency caused by frequent manual disassembly and assembly of modules in the related art can be solved. Only by pushing the first module to complete the sliding docking can modular quick plugging and locking be realized, achieving the technical effect of improving the test operation efficiency.

[0024] Server module testing usually relies on installing the module under test in a fully assembled server system for verification. In this process, components such as computer modules, power modules, fan modules, network connection modules, etc. need to be installed into the server rack respectively, and the backplane needs to be inserted into the rear fixing structure, and then the whole machine is powered on for testing. When the test is over or components (such as the backplane) need to be replaced, the above components also need to be disassembled one by one to complete the removal and replacement operations of the components. This type of testing method has strong structural dependence, cumbersome assembly steps, and involves full-process repeated operations each time, resulting in low efficiency. Based on this, the present application provides a test fixture, which realizes the rapid and stable docking between the first module and the second module, and ensures the continuous reliability of the docking state during the test through a structural self-locking method.

[0025] In order to enable those skilled in the art of this technical field to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0026] Figure 1 This is a schematic diagram of the overall structure of the test fixture provided by the embodiment of the present application. A test fixture is a device used to achieve mechanical docking between different modules during the production or debugging of a server. As Figure 1 shown, the test fixture is used for docking the first module 11 and the second module 12 of the server. Exemplarily, the first module 11 generally refers to a functional module that bears components such as a server motherboard and interface slots, and the second module 12 is used to install system components such as power management, electrical signal interfaces, or backplanes. During the server backplane test, through the docking of these two, power supply tests, signal integrity verification, and system communication verification can be carried out. Among them, the test fixture includes a test platform 2. The upper surface of the test platform 2 is used to install or support multiple components, including the first module 11 and the second module 12.

[0027] The first module 11 is slidably installed on the test platform 2, which means that the first module 11 can move along a preset direction without detaching from the test platform 2. The first module 11 moves closer to the second module 12 along the preset sliding direction and docks with the second module 12. That is, the sliding direction is usually linearly arranged with the position where the second module 12 is located to ensure the accuracy of the sliding docking. In actual operation, the operator can manually push the first module 11 to move along the sliding direction, making it gradually approach the second module 12 and complete the docking process. Exemplarily, a sliding fit structure is provided between the test platform 2 and the first module 11, which may include slide rails, guide blocks, rolling components, or other low-friction elements to ensure that the first module 11 runs smoothly during the sliding process and will not cause difficult operation or inaccurate displacement due to excessive friction. During the sliding process of the first module 11, its docking surface gradually approaches the docking area of the second module 12, and finally realizes electrical connection or physical positioning. By setting the test platform 2 and the slidably installed first module 11, the control of the module movement path during the docking process is realized, and the mechanical consistency and operation efficiency of the module docking are improved.

[0028] Meanwhile, the test fixture further includes at least one locking component 3, which is used to keep the relative positions of the first module 11 and the second module 12 stable after docking, preventing loosening, dislocation or accidental separation during the test. The locking component 3 includes a transmission member 31, a rotating member 322, and a locking mechanism 33 which is arranged in contact with the rotating member 322. Among them, the transmission member 31 is installed on the outer side wall of the first module 11 and is a component that moves together with the first module 11. The rotating member 322 is rotatably connected to the outer side wall of the second module 12, and the transmission member 31 is meshed with the rotating member 322. During the process of the first module 11 sliding closer to the second module 12, relative movement occurs between the transmission member 31 and the rotating member 322, thereby driving the rotating member 322 to rotate in a direction consistent with the sliding direction. The transmission member 31 and the rotating member 322 are connected by a meshing structure, and the tooth profiles match each other to ensure effective transmission of force and displacement linkage.

[0029] The locking mechanism 33 is arranged on the rotating member 322 and is used to restrict the rotation direction of the rotating member 322 to ensure that it can only rotate in one direction. Through the locking mechanism 33, the rotating member 322 rotates unidirectionally in the direction of the first module 11 approaching the second module 12, that is, the rotating member 322 is allowed to rotate freely in one direction and is locked in the opposite direction, thereby forming a self-locking effect. At the same time, the docking state of the first module 11 and the second module 12 is maintained. Through the combined setting of the transmission member 31, the rotating member 322 and the locking mechanism 33, during the process of the first module 11 sliding towards the second module 12 and completing docking, the locking component 3 will act synchronously to achieve automatic locking after the modules are docked, without additional manual intervention or auxiliary operations. This structural form not only improves the operation efficiency, but also enhances the structural stability during the test, reducing problems such as poor contact, data deviation or test interruption caused by module displacement. At the same time, this structure is also convenient for repeated use and high-frequency testing, and has good maintainability and adaptability.

[0030] In one embodiment, in order to further improve the structural safety and stability during the docking process of the first module 11 and the second module 12, the test fixture further includes at least one buffer protection component 4. The function of the buffer protection component 4 is to form a physical buffer area during the module docking process, and absorb the impact force caused by differences in operation speed, force or module self-weight through elastic deformation, thereby reducing the risk of direct collision between the modules, protecting key structural parts and extending the service life of the equipment. Specifically, Figure 2 is a schematic structural diagram of the buffer protection component provided by the embodiment of the present application. As Figure 2As shown in the figure, the buffer protection component 4 includes a docking member 41 installed on the first module 11 and an elastic buffer member 42 correspondingly installed on the second module 12; the docking end of the docking member 41 extends to be flush with or beyond the side wall edge of the first module 11, and the elastic end of the elastic buffer member 42 extends beyond the side wall edge of the second module 12; when the first module 11 and the second module 12 are docked, the docking end of the docking member 41 abuts against the elastic end of the elastic buffer member 42, and the elastic buffer member 42 is in a compressed state.

[0031] In this embodiment, the docking member 41 is a rigid member, and its structural feature is that the docking end extends along the sliding direction to be flush with the side wall edge of the first module 11 or slightly beyond this edge to ensure that contact with the elastic buffer member 42 occurs first before the modules are nearly completely docked. The elastic buffer member 42 is arranged at the corresponding position of the second module 12, and its structure includes an elastic end that extends towards the first module 11 and protrudes beyond the side wall edge of the second module 12 in the non-contact state, making it the first force-bearing member on the docking path of the modules. For example, the elastic buffer member 42 can be made of elastic rubber, a spring or other materials or combined structures with compression and rebound performance. During the process of the first module 11 sliding forward and approaching the second module 12, the docking end of the docking member 41 will first abut against this elastic end. When the first module 11 continues to slide, the elastic buffer member 42 is stressed and undergoes elastic compression, thereby absorbing part of the kinetic energy brought by the sliding inertia. During the entire docking process, the working principle of the buffer protection component 4 is based on the opposite arrangement and relative movement of the docking member 41 and the elastic buffer member 42. When the sliding direction of the first module 11 is the same as the extending direction of the elastic buffer member 42 and contact occurs, the elastic buffer member 42 undergoes controlled compression and continuously releases a reaction force in the compressed state to offset or weaken the impact force of the module continuing to move. The occurrence of this buffer deformation can reduce the probability of rigid collision between the module structures and improve the stability of the docking process between the modules. In summary, by setting the buffer protection component 4, the test fixture can effectively prevent problems such as deformation of the module end face and damage to the electrical connection end caused by rapid sliding, excessive inertia or operation errors, improve the overall reliability and fault tolerance of the test fixture, and provide a safer and more stable operation guarantee for the test process.

[0032] In a specific embodiment, the docking member 41 includes a first mounting block 411 and a docking rod 412; the elastic buffer member 42 includes a second mounting block 421, a buffer spring 422, and a buffer rod 423; the docking rod 412 is mounted on the top surface of the first module 11 through the first mounting block 411, and the axial direction of the docking rod 412 is parallel to the sliding direction of the first module 11; the second mounting block 421 is correspondingly mounted on the top surface of the second module 12, and a through hole is provided on the second mounting block 421, and the buffer rod 423 passes through the through hole and is slidably connected to the through hole; a docking block 424 is provided at one end of the buffer rod 423 close to the docking rod 412, the buffer spring 422 is sleeved on the buffer rod 423, and one end thereof is connected to the docking block 424 and the other end is connected to the second mounting block 421; wherein, when the first module 11 and the second module 12 are docked, the docking rod 412 abuts against the docking block 424, and the buffer spring 422 is in a compressed state.

[0033] In this embodiment, the first mounting block 411 is fixedly mounted on the top surface of the first module 11, and structurally serves as a support member for installing and fixing the position and attitude of the docking rod 412. The docking rod 412 is of an elongated rod-like structure, and its axial direction is set parallel to the sliding direction of the first module 11, ensuring that during the process of the first module 11 sliding close to the second module 12, the docking rod 412 can extend forward stably along the docking direction and come into contact with the corresponding structure of the elastic buffer member 42 in advance before touching the main body of the second module 12. The length and the extending distance of the docking rod 412 can be preset according to the module structure to establish a buffer path at the initial stage of docking. The second mounting block 421 is fixedly mounted on the top surface of the second module 12 and serves as a mounting base for the buffer structure. A through hole is provided in the second mounting block 421, and a sliding fit connection is formed between the through hole and the buffer rod 423. This sliding connection allows the buffer rod 423 to perform axial movement during the docking process, thereby creating space for the spring deformation. The buffer rod 423 is an elongated straight rod, one end of which passes through the second mounting block 421 and enters the through hole, and the other end extends toward the docking rod 412, and a docking block 424 is provided at one end of it close to the docking rod 412. The docking block 424 is a rigid limiting structure, and when it comes into direct contact with the docking rod 412, it forms an initial stress surface, causing the buffer structure to start responding. The buffer spring 422 is sleeved outside the buffer rod 423, one end of which is fixedly connected to the docking block 424 and the other end is fixedly connected to the second mounting block 421. This setting forms a compressed elastic space, and the buffer rod 423 slides along the through hole under the action of an external force, thereby causing the spring to be axially compressed.

[0034] Specifically, when the first module 11 slides to the docking position, the docking rod 412 abuts against the docking block 424 on the buffer rod 423. When the first module 11 continues to slide, it pushes the buffer rod 423 to slide inward, causing the gradual compression of the buffer spring 422. During the complete fitting of the modules, the buffer spring 422 is in a compressed state and maintains a reaction force to counteract the impact inertia brought by the sliding of the modules, ensuring the softness of the contact action and the buffering of the structure. The entire process realizes the gradual release of force through the deformation of the spring, preventing the hard collision of the module structure and reducing the wear or damage of the components at the end of the module. At the same time, a limiting structure is also provided at the other end of the buffer rod 423, such as a plate structure with a diameter larger than the through hole, to reduce the occurrence of the buffer rod 423 disengaging from the through hole.

[0035] In one embodiment, to further improve the guiding accuracy and lateral stability during the sliding of the first module 11, the test fixture further includes at least two limiting components 5, and at least one limiting component 5 is provided on one side of the first module 11. Figure 3 The structural schematic diagram of the limiting component provided by the embodiment of the present application is shown in Figure 3 As shown in the figure, the limiting component 5 includes a limiting rod 51 and a limiting plate 52; the limiting plate 52 is vertically arranged on the test platform 2, and a strip-shaped limiting hole is provided on the limiting plate 52, and the long axis direction of the limiting hole is parallel to the sliding direction of the first module 11; one end of the limiting rod 51 is connected to the outer side wall of the first module 11, and the other end passes through the limiting hole and is slidably connected to the limiting hole; a limiting block 53 is provided at the end of the limiting rod 51 away from the first module 11, and the limiting block 53 is arranged in contact with the side wall of the limiting plate 52.

[0036] In this embodiment, the limiting plate 52 is vertically mounted on the upper surface of the test platform 2, and is usually made of a rigid material to ensure that it does not deform when subjected to the lateral force applied by the limiting rod 51. A strip limiting hole is provided on the limiting plate 52, and the long axis direction of the limiting hole is parallel to the sliding direction of the first module 11, so that the limiting rod 51 can achieve linear motion parallel to the sliding path in the limiting hole. One end of the limiting rod 51 is fixedly connected to the outer wall of the first module 11 to ensure that the limiting rod 51 moves with it during the sliding process of the first module 11. The other end passes through the limiting hole and forms a sliding fit connection with it. This sliding connection method ensures the free movement ability of the limiting rod 51 in the sliding direction of the module. A limiting block 53 is provided at one end of the limiting rod 51 away from the first module 11. The limiting block 53 is slightly larger than the limiting rod 51 body, is usually set at the end of the limiting rod 51, and is set in contact with the side wall of the limiting plate 52. During the sliding of the first module 11, the limit block 53 moves in the limit hole and is always close to the inner wall of the limit hole, thereby structurally limiting the possibility of the limit rod 51 deviating from the path of the limit hole. The existence of the limit block 53 can also prevent the limit rod 51 from escaping from the limit hole, further enhancing the structural safety of the component. The limit component 5 uses mechanical guidance and lateral support to ensure that the first module 11 always maintains the preset path during the sliding docking process, avoiding problems such as docking position deviation, plug-in angle error, or uneven force on the backplane interface due to module offset. At the same time, the structure is simple and versatile, and can be adapted to first modules 11 of different specifications. By setting at least one limit component 5 on one side of the first module 11 and setting a second limit component 5 according to actual symmetry requirements, a more precise bilateral constraint can be achieved, further improving the mechanical consistency and repeatability of docking. It can be seen that the setting of the limit assembly 5 can not only reduce the deviation and shaking of the first module 11 during the sliding docking process, but also maintain the linear consistency of its sliding path through mechanical limiting, reduce module misalignment or oblique insertion caused by operational deviation, external force interference or structural gap, thereby ensuring the accuracy and reliability of the docking action.

[0037] In a specific embodiment, the test platform 2 is provided with a plurality of rolling components; the first module 11 is placed on the rolling components and slides toward the second module 12 through the rolling components; the second module 12 is installed on the upper surface of the test platform 2 through a support plate 22 and is located at the end of the position where the first module 11 slides through the rolling components.

[0038] In this embodiment, the test platform 2 serves as the structural foundation of the entire test fixture. A plurality of rolling components are provided thereon, which are used to carry the first module 11 and guide it to slide along a preset direction to dock with the second module 12. The setting of the rolling components can effectively reduce the frictional resistance during the sliding of the module, improve the sliding smoothness and operation convenience, and reduce the operation discomfort and structural wear problems caused by large friction and serious jamming in the traditional slide rail structure. Specifically, a plurality of rolling components are evenly arranged on the upper surface of the test platform 2 and arranged along the sliding direction of the first module 11. This direction is usually a linear straight line direction. Each rolling component has a self-rotation function. Exemplarily, its structural form can be a roller or a ball bearing assembly. The bottom plate of the first module 11 is attached to the upper surfaces of the plurality of rolling components, forming a supporting contact relationship. Through this structural setting, the first module 11 can easily slide along the rolling components without being lifted or applying a large driving force, achieving rapid docking. The rolling components can be reasonably spaced according to the weight, length and support requirements of the first module 11 to ensure that the first module 11 is always in a uniformly stressed state during the sliding process, avoiding tilting, sinking or shaking caused by uneven support.

[0039] The second module 12 is fixedly installed on the upper surface of the test platform 2, and its bottom is connected to the platform through a support plate 22. The support plate 22 has good rigidity and stability to ensure that the second module 12 always remains fixed during the test. The installation position of the second module 12 is at the end point of the sliding path of the first module 11, that is, the first module 11 can be moved to the position where it docks with the second module 12 by sliding along the rolling components. Through the structural setting of this embodiment, the test platform 2 not only ensures the sliding docking efficiency of the module, but also improves the stability and operation comfort of the test operation. The setting of the rolling components reduces the friction force, enabling the operator to more easily push the module for positioning without having to repeatedly adjust the posture or consume extra physical strength, improving the operation efficiency of the overall test process. Especially in the server backplane detection scenario with multiple batches of tests and frequent repeated plugging and unplugging operations, this structure can effectively reduce the manual burden.

[0040] Specifically, the rolling components are roller shafts 21; a plurality of roller shafts 21 are arranged at intervals along the sliding direction of the first module 11, and the axial direction of the roller shafts 21 is perpendicular to the sliding direction of the first module 11; both ends of the roller shafts 21 are rotatably connected to the test platform 2, and the bottom plate of the first module 11 is attached to the upper surfaces of the plurality of roller shafts 21.

[0041] In this embodiment, the application of the roller 21 not only effectively reduces the friction resistance during the sliding process of the first module 11, but also realizes the dynamic balance and structural stability of the module during the sliding process through the evenly distributed rolling support. Specifically, multiple rollers 21 are arranged at intervals along the sliding direction of the first module 11, that is, they are arranged in sequence according to the preset spacing on the sliding path of the test platform 2. This structural method of arranging and equidistantly arranged along the sliding direction can ensure that the first module 11 is always in a state of multi-point contact and multi-axis support throughout the sliding stroke, and there will be no problems such as support interruption, force concentration or local settlement. The spaced arrangement is not only conducive to dispersing the load, but also can be flexibly adjusted according to the size and mass of the first module 11, so that the distribution of rollers 21 meets the support requirements of different modules and has good structural adaptability.

[0042] The axis direction of the roller 21 is perpendicular to the sliding direction of the first module 11. This arrangement ensures that the rotation direction of the roller 21 is consistent with the sliding path of the module to reduce the friction resistance during the sliding process. Each roller 21 can rotate freely around its own axis when the first module 11 slides, thereby forming a smooth linear rolling support, avoiding the sticking or jumping problems common in traditional planar contact support structures. In terms of installation method, both ends of each roller 21 are rotatably connected to the test platform 2, that is, the roller 21 is installed on the platform through a bearing or a rotating slot structure. This rotating connection structure not only ensures that the roller 21 has rotational freedom in the axial direction, but also fixes its radial position to prevent the roller 21 from moving or loosening during the sliding of the module. Exemplarily, the roller 21 body is usually made of metal or plastic material, has high wear resistance and rotation stability, and is suitable for long-term high-frequency operation.

[0043] During the docking operation, the first module 11 slides smoothly along the surface of the roller 21 under manual push, and the roller 21 rotates accordingly to achieve low-resistance, high-precision guided movement. The number and arrangement density of the rollers 21 are configured according to the bottom length and load-bearing requirements of the module to ensure that the first module 11 has multiple rollers 21 to support it at any position, maintaining its horizontal state and avoiding tilting, tilting or shaking. In summary, the setting of the roller 21 structure optimizes the flatness and continuity of the module sliding path, improves the ease of operation, and can achieve longer distance sliding with less driving force, effectively improving the efficiency of test preparation.

[0044] Furthermore, in order to further improve the sliding operation convenience and control accuracy of the first module 11, an electric telescopic rod for pushing the first module 11 is added to the test platform 2. The electric telescopic rod can replace the manual push-pull operation and realize the movement of the first module 11 along the preset sliding direction in a mechanism-driven manner, thereby improving the stability, consistency and control safety of the sliding docking.

[0045] In this specific embodiment, the electric telescopic rod is disposed on the upper surface of the test platform 2 and is located at the rear side of the sliding path of the first module 11, that is, at the end far from the second module 12. The electric telescopic rod is arranged parallel to the sliding direction of the first module 11 to ensure that the force transmission direction during the pushing process is consistent with the module movement direction, avoiding offset or structural distortion. The fixed end of the electric telescopic rod is mounted on the test platform 2 through a connecting bracket, and its output end is connected to the rear end face of the first module 11 through a universal joint. The electric telescopic rod internally integrates a motor drive assembly, and its motor can be a DC motor or a stepper motor, and the linear telescopic movement of the rod body is realized by driving a screw mechanism. During the actual operation process, the electric telescopic rod receives an external control signal and is started through a button, a switch, remote control or a preset program. In the test preparation stage, after the electric telescopic rod is started, its output end slowly extends, pushing the first module 11 connected thereto to move along the sliding path towards the second module 12, and the docking of the modules is achieved at the sliding end. After the test is completed, the electric telescopic rod performs a contraction action, driving the first module 11 to slide back to the initial position for replacing the backplane or performing the next round of test tasks. In summary, through the setting of the electric telescopic rod, the automation degree and operation efficiency of the overall test fixture are improved. And it should be noted here that the electric telescopic rod can be flexibly selected according to specific usage requirements and is not specifically limited herein.

[0046] In a specific embodiment, Figure 4 The structural schematic diagram of the locking component provided by the embodiment of the present application. As Figure 4 shown, the locking component 3 further includes a protective plate 34; the transmission member 31 includes a rack 311; the rotating member 322 includes a gear 321 and a rotating shaft; Figure 5 The partial structural schematic diagram of the latching mechanism provided by the embodiment of the present application. As Figure 5 shown, the latching mechanism 33 includes a ratchet 331, a pawl 332, a positioning spring 333 and a positioning plate 334; the protective plate 34 is U-shaped, and its two ends are connected to the outer side wall of the second module 12 and enclose a cavity with the outer side wall of the second module 12, and the gear 321 is arranged in the cavity;

[0047] One end of the rotating shaft is rotatably connected to the outer side wall of the second module 12, and the other end sequentially passes through the gear 321, the protective plate 34 and the ratchet 331; both the gear 321 and the ratchet 331 are sleeved on the rotating shaft without relative sliding; the rack 311 is mounted on the outer side wall of the first module 11, and the rack 311 is in meshing transmission with the gear 321;

[0048] The pawl 332 includes a positioning portion 3321 and an abutting portion 3322 connected in sequence. The abutting portion 3322 abuts against the ratchet wheel 331. One end of the positioning portion 3321 away from the abutting portion 3322 is sleeved on the connecting rod 335 and is rotatably connected to the connecting rod 335. One end of the positioning spring 333 is connected to the top surface of the positioning portion 3321, and the other end is connected to the positioning plate 334, and the positioning spring 333 is in a compressed state. Both the connecting rod 335 and the positioning plate 334 are installed on the protective plate 34.

[0049] Wherein, through the abutting of the abutting portion 3322 against the ratchet wheel 331, the gear 321 and the rotating shaft rotate unidirectionally in the direction in which the first module 11 approaches the second module 12, and the docking state of the first module 11 and the second module 12 is maintained.

[0050] In this embodiment, the protective plate 34 has a U-shaped structure, and its two ends are respectively fixedly connected to the outer side walls of the second module 12, and a semi-closed cavity space is formed in structure with the second module 12. This cavity is used to accommodate and protect the gear 321, reduce the external force impact or foreign object interference during operation, and at the same time improve the overall mechanical integrity and safety of the device. The protective plate 34 can be made of metal sheet or high-strength plastic, taking into account the convenience of assembly and processing while ensuring rigidity. The rotating shaft passes through the cavity and bears the gear 321 and the ratchet wheel 331. One end of it is rotatably connected to the outer side wall of the second module 12 through a bearing or a rotating shaft seat, and the other end sequentially passes through the gear 321, the protective plate 34 and the ratchet wheel 331. Both the gear 321 and the ratchet wheel 331 are rotating elements sleeved on the rotating shaft, and there is no relative sliding with the rotating shaft in structure, that is, they are fixedly connected to the rotating shaft by means of interference fit, keyway connection or screw fixation, etc., to ensure synchronous rotation during rotation without slipping or relative rotation. The rack 311, as the transmission member 31, is fixedly installed on the outer side wall of the first module 11 and is arranged along its sliding direction. The tooth surface of the rack 311 meshes with the gear 321 arranged in the cavity. During the process of the first module 11 sliding closer to the second module 12, the rack 311 pushes the gear 321 to rotate along the sliding direction, driving the rotating shaft to rotate synchronously, and realizing the mechanical response to the sliding action of the module. The module number and tooth pitch of the gear 321 match those of the rack 311 to ensure the meshing accuracy and transmission efficiency.

[0051] The locking mechanism 33 is arranged on the side of the rotating shaft away from the gear 321, and is mainly composed of a ratchet 331, a pawl 332, a positioning spring 333 and a positioning plate 334. The ratchet 331 is fixed on the rotating shaft and forms a meshing structure with the pawl 332. The pawl 332 includes a positioning portion 3321 and an abutting portion 3322 connected in sequence, wherein the abutting portion 3322 directly abuts against the tooth surface of the ratchet 331 to form a one-way restriction. When the gear 321 drives the rotating shaft to rotate in the direction of the first module 11 approaching the second module 12, the pawl 332 is allowed to jump teeth due to the structural setting, and the movement is not restricted; when trying to rotate in the reverse direction, the pawl 332 is embedded in the tooth gap of the ratchet 331, forming a mechanical blockage, limiting the reverse movement of the rotating shaft, thereby realizing the one-way locking function. The positioning portion 3321 is a structural section connecting the pawl 332, and its end away from the abutting portion 3322 is sleeved on the connecting rod 335 and is rotatably connected to the connecting rod 335. The connecting rod 335 provides a rotation fulcrum for the pawl 332, so that it has the ability to swing tangentially around the rotation axis. One end of the positioning spring 333 is connected to the top surface of the positioning portion 3321, and the other end is fixedly connected to the positioning plate 334 installed on the protective plate 34. The spring is in a compressed state and always applies a return force inward to ensure that the pawl 332 fits the surface of the ratchet 331 to achieve adaptive meshing. Through the structural combination of this embodiment, when the first module 11 moves along the sliding direction to approach the second module 12, the rack 311 pushes the gear 321 to rotate and simultaneously drives the rotating shaft to rotate in the clockwise direction, and the pawl 332 jumps teeth to cooperate without hindering movement. When the first module 11 stops at the docking position, if it attempts to slide in the opposite direction, the ratchet 331 will be blocked by the pawl 332, the rotating shaft cannot rotate counterclockwise, and the gear 321 cannot reverse, thereby achieving the structural locking of the first module 11 and the second module 12. This structure not only has a holding function, but also improves the reliability of module fixation during the test and reduces contact looseness caused by operational errors.

[0052] In a specific embodiment, at least one operating handle 23 is installed on the first module 11 .

[0053] The operating handle 23 is used to provide a part for the operator to apply force, so that the first module 11 can slide along the test platform 2 to the docking position with the second module 12 without the aid of additional tools. At the same time, after the test is completed, the first module 11 can also be quickly withdrawn through this handle. By setting the shape, position and installation method of the operating handle 23, the usability and structural practicality of the device can be improved. Specifically, the operating handle 23 is installed on the outer wall of the first module 11, and its specific position can be adjusted according to the sliding direction of the first module 11 and the operator's usage habits. It is usually set at the front end, top or side of the first module 11 to ensure that the operator can naturally grasp and stably apply force when pushing forward or pulling backward. The structure of the operating handle 23 can be common holding forms such as annular, strip-shaped or T-shaped, and its surface is treated with anti-slip or covered with a flexible material to improve the operation feel and reduce the fatigue caused by long-term use. To ensure the structural strength and stability during operation, the handle is usually made of metal and is reliably fixed to the shell or frame of the first module 11 by means of screws, studs or embedded nuts. By setting the operating handle 23, the operator can obtain a more direct and stable mechanical support when pushing or pulling the first module 11 to slide. At the same time, this structure also improves the efficiency and safety of the test operation. Especially in the application environment where the first module 11 has a large mass or a long sliding path, the setting of the operating handle 23 can reduce the operation intensity and improve the comfort of the overall operation.

[0054] The embodiment of the present application also provides a server backplane test device, including a computer module, a connection device module and the test fixture of the above embodiment; the connection device module is provided with a backplane installation area, and the server backplane is installed in the connection device module through the backplane installation area; the computer module is docked with the server backplane; wherein, the computer module is the first module 11, and the connection device module is the second module 12.

[0055] In this embodiment, the computer module in the test device is used to simulate the main control system unit when the server is working. Components such as a motherboard, a processor, a memory module, and an interface module are usually installed inside it, and it can provide functional interfaces such as data communication, power connection, and signal interaction. As a test-end access device, the computer module has a docking connector structure for plugging into the backplane at its docking end face, including but not limited to a power plug or a high-speed signal port, etc. During the test, the computer module moves towards the connection device module through a sliding fit structure and establishes a physical and electrical connection with the server backplane, so as to realize the test call of each functional path of the backplane. The connection device module serves as the installation and fixing structure of the server backplane, and a backplane installation area is provided thereon. This backplane installation area is a specially reserved position area for installing the server backplane, and its structural dimensions, mounting hole positions, and electrical port positions are all set according to the backplane specifications actually required for testing. The server backplane is fixed in the backplane installation area by means of buckles or bolts, etc., and its interface is kept facing the computer module to complete the docking connection. The test fixture in the test device constitutes the structural connection platform between the first module 11 and the second module 12, and is used to guide the computer module to slide to the connection device module to realize the alignment and plugging of the backplane. The locking component 3, the limiting component 5, the rolling structure, and the buffer protection structure in the test fixture work together to ensure the guiding accuracy, docking stability, and position locking ability of the computer module during the sliding process, and avoid problems such as plugging misalignment and impact damage caused by human misoperation or the weight of the module.

[0056] Furthermore, the computer module is used to install the server motherboard and the cooling fan; the connection device module is also used to install the network connection device and the power management device.

[0057] In the server backplane test device, the computer module is specifically used to install components such as the server motherboard and the cooling fan. The server motherboard, as the core processing unit, is the basic platform for executing data processing, interface control, and communication protocol parsing. A central processor, memory slots, expansion interfaces, a storage controller, and various peripheral interface modules are integrated thereon. During the test, the motherboard on the computer module is electrically connected to the server backplane through the backplane connection interface, so as to simulate the working state during the actual operation of the server and verify and detect the signal path, power distribution ability, and interface matching relationship of the backplane. In order to ensure the continuous and stable operation of the motherboard during the test, a cooling fan structure is also equipped in the computer module. This fan is usually installed on the top surface, side wall of the computer module or near the heat source, and ventilates and cools the motherboard area through axial or transverse air flow methods, preventing the processor or other device groups from overheating due to long-term operation, and ensuring that each component works under temperature control conditions. The introduction of the cooling fan not only extends the service life of the motherboard, but also improves the safety and stability of the entire test system.

[0058] The connection device module serves as the second module 12, and its functions are not limited to installing the server backplane. It is further used to install network connection devices and power management devices. The network connection devices include, but are not limited to, gigabit Ethernet network cards, 10-gigabit fiber optic interface modules, or other high-speed network adapters, which are used to simulate the network communication capabilities of the server backplane in actual deployment scenarios, and through connecting to test ends or load devices, to achieve the test and verification of the on / off state, bandwidth stability, and data throughput capacity of the backplane network interfaces. Through the network devices on the connection device module, interface testing, protocol consistency detection, rate fault tolerance analysis, etc. can be carried out.

[0059] The connection device module is also installed with a power management device, which is used to provide an adjustable and monitorable power supply environment for the server backplane and its connected components. The power management device may include a power module, a voltage converter, a power distribution unit, a status monitoring board card, etc. It is not only responsible for converting the input voltage into multiple stable output powers required by each backplane, but also can monitor and record parameters such as current, voltage, and power consumption in real time, providing data basis for fault judgment, overload protection, and performance analysis during the test process. Through the setting of the power management device, operations such as the determination of the backplane power supply capacity, the verification of the shunting ability, and the dynamic load simulation can be achieved without relying on the overall server power supply system. In summary, the computer module and the connection device module respectively integrate the components of the test drive side and the tested cooperation side in terms of structural configuration, improving the independence and functional integrity of the test, and also providing multi-dimensional support for the test of the server backplane. And it should be further noted here that the specific installation positions of the components in the computer module and the connection device module can be flexibly set according to the test needs, and the specific test process and test content can be adjusted according to the requirements, and no further restrictions are made here.
