Description

Technical Field

[0001] This invention belongs to the field of slide rail testing technology, specifically relating to a mechanical testing device for server slide rails. Background Technology

[0002] With the rapid development of the Internet, servers are becoming increasingly common and the requirements for them are constantly increasing. The density of hardware such as storage devices and power modules placed in server chassis is becoming denser, causing them to bear increasingly greater loads.

[0003] The accompanying slide rails, as a crucial component, must not only withstand high loads but also allow for normal pull-out operation. Their superior performance is a fundamental guarantee for the server's performance.

[0004] Conventional slide rail load testing typically employs semi-automatic equipment, requiring a full-load counterweight test on the server chassis. For example, patent CN114002062A, titled "Server Rail Performance Testing Device and its Usage Method," discloses a testing device capable of measuring the load-bearing deformation of the slide rail and the sliding and pulling force of the server on the rail. However, its thrust testing method has limitations. Specifically, the thrust test involves horizontally pulling the server with a traction bracket and measuring the resistance change curve during the server's sliding on the rail. This method primarily reflects the sliding friction performance between the rail and the server, and cannot directly apply thrust to the side or front of the server chassis to test the reliability of the slide rail locking mechanism under lateral or longitudinal thrust. Furthermore, the device's fixed structural layout and lack of height adjustment in the thrust detection section make it difficult to adapt to server chassis of different heights, limiting its versatility. For example, patent number CN118362272A, titled "Server Mechanical Testing Fixture, Method, and Apparatus," relates to the structural reliability testing of a server as a whole under simulated vibration conditions. Its core lies in using a vibration table to excite the server and combining image and acceleration data to analyze the server's resonance and deformation. This technology primarily focuses on assessing the structural strength and dynamic stability of the entire server, rather than specifically testing the load-bearing capacity and locking function of a server slide rail. Its testing scenario, method, and purpose are fundamentally different from the mechanical performance testing of slide rails, and therefore cannot be used to evaluate the performance of slide rails in terms of static load-bearing capacity, smoothness of extension and retraction, and locking reliability. In summary, the load testing of slide rails in the prior art is complex, time-consuming, inefficient, and prone to errors. Meanwhile, the thrust testing of slide rails is usually carried out manually, which is often inefficient and has poor reliability. Summary of the Invention

[0005] Purpose of the invention: To address the problems of cumbersome, inefficient, and manually-dependent testing processes in existing server slide rail testing technologies, as well as the inability to simultaneously and accurately test load-bearing and locking performance and poor equipment versatility, this invention provides an integrated, automated, and adjustable server slide rail mechanical testing device, aiming to achieve rapid, accurate, and integrated testing of vertical load-bearing deformation and horizontal locking reliability of the slide rail.

[0006] Technical solution: A server slide rail mechanical testing device, including a testing base, a gravity testing device, a thrust testing device, and a display device.

[0007] In a further embodiment, the bottom of the detection base is provided with casters to facilitate the overall movement and positioning of the device.

[0008] In a further embodiment, the gravity detection device includes a first support frame and a first drive motor assembly. The first support frame is fixed to the top of the detection base, and one end of it has a horizontally extending first extension arm. The first drive motor assembly is fixed to the end of the first extension arm, and its output end is vertically downward and equipped with a pressure sensor. This device is used to apply a vertically downward pressure to the top of a server chassis mounted on a rack.

[0009] In a further embodiment, the thrust detection device includes a second support frame, a second drive motor assembly, and a linear slide rail assembly. The linear slide rail assembly is vertically mounted on the side of the detection base, and the second support frame is slidably mounted on the linear slide rail assembly and can move up and down along it to adjust its height. One end of the second support frame has a horizontally extending second extension arm, and the second drive motor assembly is fixed to the end of the second extension arm, with its output end horizontally positioned and equipped with a pressure sensor. This device is used to apply a horizontal thrust to the side or front of the server chassis.

[0010] In a further embodiment, the display device includes a display screen and a rotating arm. One end of the rotating arm is fixed to the first support frame of the gravity detection device, and the other end is connected to the display screen. The display screen can rotate around the rotating arm to adjust the viewing angle. It integrates a control system for setting the target pressure values ​​for gravity and thrust detection, controlling motor operation, displaying pressure sensor data in real time, and judging test results.

[0011] In a further embodiment, both the first drive motor assembly and the second drive motor assembly are servo electric cylinders or servo motors combined with ball screws, which can achieve precise loading and holding of pressure.

[0012] Compared with the prior art, the present invention has the following beneficial effects: High integration and automation improve efficiency: The slide rail load capacity test (gravity test) and locking reliability test (thrust test) are integrated into one device. The load is automatically applied by motor drive, eliminating the cumbersome manual counterweight step in the traditional load test, simplifying the operation process, greatly reducing labor costs, and improving the overall testing efficiency.

[0013] Adjustable parameters and precise measurement ensure accuracy: Through the display device, operators can precisely set the target pressure values ​​required for gravity and thrust tests in advance. The drive motor assembly is precisely loaded according to the set values, and its built-in pressure sensor provides real-time feedback of actual pressure and displacement data, ensuring the consistency of test conditions and the accuracy of result judgment, and avoiding subjective errors in manual testing.

[0014] Adjustable thrust detection height enhances applicability: The thrust detection device achieves flexible height adjustment of the second drive motor assembly through a linear slide rail assembly, enabling its force application point to accurately correspond to the force-bearing parts of server chassis of different heights. This greatly improves the device's adaptability to different server models and expands its application range.

[0015] Compact design and easy mobility for an optimized user experience: The casters at the bottom of the testing base allow the entire testing equipment to be easily moved within the laboratory or along the production line, facilitating connection to different testing stations or server racks, enhancing the flexibility of equipment deployment and ease of use.

Server rack; Detailed Implementation The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1 to 3 As shown, a server slide rail mechanical testing device mainly includes a testing base 1, a gravity testing device 2, a thrust testing device 3, and a display device 4.

[0026] The testing base 1 serves as the basic support platform for the equipment, employing a rigid frame structure. The control system and power module can be housed internally. Four locking casters 5 are installed at the bottom corners, allowing the equipment to be easily moved and remain stable once in place.

[0027] Gravity detection device 2, such as Figure 4 As shown, it is fixedly installed at the top center of the detection base 1. It includes an inverted L-shaped first support frame 21, the vertical part of which is fixed to the base 1, and the horizontal part forms a first extension arm 211. At the end of the first extension arm 211, a first drive motor assembly 22 is fixed by a mounting plate. The first drive motor assembly 22 is preferably a servo electric cylinder, whose piston rod (output end) extends vertically downward, and the end is equipped with a pressure sensor (not shown separately in the figure, which can be integrated into the electric cylinder or installed on the pressure head) and a force-applying pressure head for contacting the top of the server chassis. This device is used to simulate the vertical pressure on the slide rail when the server is fully loaded.

[0028] Thrust detection device 3, such as Figure 5As shown, it is installed on one side (usually the front or side) of the detection base 1. It includes a vertically mounted linear slide rail assembly 33, which is securely connected to the side of the detection base 1 by a bracket. A second support frame 31 is connected to the linear slide rail assembly 33 by a slider and can be manually or driven by an additional small adjusting motor to slide up and down along the linear slide rail. The second support frame 31 is also inverted L-shaped, and its horizontal portion forms a second extension arm 311. At the end of the second extension arm 311, a second drive motor assembly 32 is installed. The second drive motor assembly 32 is also a servo electric cylinder, but its installation direction is horizontal, the piston rod extends horizontally, and the end is also equipped with a pressure sensor and a force-applying head or push plate suitable for lateral or front thrust.

[0029] Display device 4, such as Figure 6 As shown, the system includes a display screen 41 and a mechanical rotating arm 42. One end of the rotating arm 42 is fixed to the column of the first support frame 21 by a clamp or bolt, and the other end is connected to the display screen 41. The rotating arm 42 allows the display screen 41 to rotate at multiple angles and directions, facilitating observation by the operator from different positions. The display screen 41 is a touch screen, integrating the core controller of the equipment (such as a PLC or industrial computer) and running internal control software. The operator can set test parameters (such as pressure value, thrust value, holding time, etc.) through the touch screen, start the test program, and view the pressure-displacement curve, test status, and final pass / fail judgment result in real time.

[0030] Working principle: Before testing, secure the server rack 8 with the server rail 7 installed, and pull the server chassis 6 out through the rail 7 until it is fully extended and locked in place.

[0031] Gravity (load-bearing) test (e.g.) Figure 7 As shown): The target downward pressure value (simulating the full load weight of the server) is set via display device 4. The gravity detection program is initiated, and the piston rod of the first drive motor assembly 22 moves downward, applying a vertically downward pressure to the top center of the server chassis 6 through the pressure head until the set value is reached and maintained. The system monitors the stability of the pressure and the amount of chassis subsidence (i.e., the elastic deformation of the slide rail) through the pressure sensor within the first drive motor assembly 22 and the built-in displacement encoder (or through an external sensor). This deformation is compared with a preset standard to determine whether the load-bearing capacity of the slide rail is qualified.

[0032] Thrust (lock-up) test: Divided into front thrust test (e.g., Figure 8 (as shown) and side thrust test (as shown) Figure 9 (As shown).

[0033] Front-end test: Adjust the height of the thrust detection device 3 so that the pressure head of the second drive motor assembly 32 is aligned with the center of the front panel of the server chassis 6. Set a horizontal thrust value (simulating the thrust of an accidental collision or improper operation) via the display device 4. Start the thrust detection program, and the second drive motor assembly 32 pushes the front panel of the chassis horizontally forward. The system monitors the thrust value and observes whether the locking mechanism of the slide rail 7 disengages or slides. If the slide rail lock fails (displacement occurs) at the set thrust, it is considered unqualified.

[0034] Side test: Move the device to the side of the chassis, and adjust the thrust detection device 3 to a suitable height, aligning it with the side panel of the chassis. Apply a horizontal lateral thrust and test the locking stability of the slide rail under lateral force.

[0035] Throughout the entire testing process, all actions are controlled by the program, and data is automatically collected and judged without the need for manual intervention in reading or judging, making it efficient and objective.

[0036] Other embodiments: In another embodiment, the lifting drive of the linear guide rail assembly 33 can be integrated with a servo motor, which, in conjunction with the display device 4, enables the digital setting and automatic adjustment of height parameters, further enhancing the degree of automation.

[0037] In another embodiment, the force-applying ends of the first drive motor assembly 22 and the second drive motor assembly 32 may be equipped with a variety of replaceable pressure heads or clamps to adapt to different server chassis top structures (such as whether there are handles or grooves) and side / front contact requirements.

[0038] In another embodiment, a level and leveling feet can be installed on the detection base 1 to ensure that the device is in an absolutely level state during testing when used in conjunction with the moving wheels 5, thereby improving testing accuracy.

[0039] In another embodiment, the control system of the display device 4 may have the functions of data storage, historical query, generating test reports and uploading them via the network, which facilitates quality traceability and management.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
