Existing testing devices have significant shortcomings: functional separation necessitates the coordination of multiple devices, which is prone to errors; asynchronous testing and calibration environments lead to component deformation and positioning deviations; insufficient precision in insertion / removal displacement adjustment and a lack of real-time calibration mechanisms; unstable support structures that can easily damage the tested components; frequent power interruptions affecting test continuity; and poor versatility, making it difficult to adapt to different specifications of computer components and failing to meet the requirements for accurate, efficient, and stable testing.

[0003] To address this, we propose a computer cold start hot-plug testing device. Summary of the Invention

[0004] This invention aims to provide a computer cold start hot-swap testing device. Its core requirements include: integrating cold-state temperature control and hot-swap testing functions to simplify the testing process and reduce equipment connection errors; using the same cooling component to achieve synchronized temperature control between the testing and calibration environments, avoiding deviations caused by temperature differences; achieving precise displacement adjustment of the moving platform and testing device through a ball screw + double slide rail structure; combining laser ranging and photoelectric ranging for real-time calibration of insertion / removal displacement; optimizing the support and positioning structure to ensure safety during the testing process; integrating the power supply unit and power plug to ensure continuous and stable power supply; adapting to different specifications of computer components to improve versatility; and ultimately achieving the goals of accurate testing, simplified process, stable reliability, and strong versatility.

[0028] Example: A computer cold start hot-plug testing device, such as Figures 1-5 As shown, the device includes a test platform 1, a movable platform 2 at one top of the test platform 1, a cold-state constant temperature chamber 3 at the top of the movable platform 2, a suspension bracket 4 at one top of the test platform 1, the suspension brackets 4 corresponding to each other, a positioning bracket 5 inside the suspension bracket 4, a test component 6 movably mounted between the inner sides of the positioning brackets 5, a calibration base 7 at the bottom of the inner wall of the suspension bracket 4, the movable platform 2 corresponding to the calibration base 7, and the movable platform 2 consisting of several laterally movable support rails 8. A sealing cover 9 is located at the top of the cold-state constant temperature chamber 3. The device integrates a cold... The system features constant temperature control and hot-swap testing, enabling precise hot-swap testing of computer components under cold-start conditions without disassembly. This effectively simplifies the testing process, reduces errors caused by connecting different devices, and adapts to the cold-start hot-swap performance testing needs of various computer core components. The cold constant temperature chamber 3 and the calibration base 7 are synchronously temperature-controlled by the same cooling component 13, ensuring that the test environment and calibration environment maintain a high degree of temperature consistency. This avoids component deformation and positioning deviation caused by temperature differences, significantly improving the accuracy and reliability of test data and ensuring the reference value of test results.

[0029] like Figures 1-4 As shown, a ranging platform 10 is provided on one side of the test platform 1, and a ranging column 11 is provided at the top of the test platform 1. The ranging column 11 is cylindrical in shape and has several ranging photoelectric sensors 12 integrated around its surface. A cooling component 13 is installed on one side of the test platform 1. The cooling component 13 is electrically connected to the calibration base 7 and the cold constant temperature chamber 3. A ball screw 14 is installed between the moving platforms 2. The moving platforms 2 are engaged with the suspension bracket 4 and are driven up and down by the ball screw 14. The device integrates cold temperature control and hot-swap testing functions. It can realize accurate hot-swap testing of computer components under cold start conditions without disassembly, effectively simplifying the test process, reducing errors caused by the connection of different devices, and adapting to the cold start hot-swap performance testing needs of various computer core components. The cold constant temperature chamber 3 and the calibration base 7 are synchronously temperature controlled by the same cooling component 13, which can ensure that the temperature of the test environment and the calibration environment are highly consistent, avoiding component deformation and positioning deviation caused by temperature differences, greatly improving the accuracy and reliability of test data, and ensuring the reference value of test results.

[0030] like Figures 1-5 As shown, linear slide rails 15 are provided on both sides of the bottom of the inner wall of the positioning bracket 5. A test device 16 is arranged between the linear slide rails 15. The test device 16 is an electrical component with an integrated power plug. The top two sides of the test device 16 engage with the positioning bracket 5 and slide along the positioning bracket 5 with the help of the linear slide rails 15. The calibration base 7 is correspondingly arranged with the test device 16. There are laser rangefinders 17 on both sides of the test device 16. A power supply unit 18 is installed on one side of the test platform 1. The power supply unit 18 is electrically connected to the test device 16. The suspension bracket 4 and the positioning bracket 5 correspond to each other and cooperate closely to provide stable installation support and precise positioning constraints for the test device 16. This effectively avoids damage to the tested component caused by unstable support or positioning misalignment during hot-plugging operations, ensuring the safety of the testing process. The test device 16 integrates a power plug, which can directly and quickly connect to the computer component under test without the need for additional power adapter components. At the same time, the power supply unit 18 on one side of the test platform 1 is stably electrically connected to the test device 16, which can continuously provide stable power to the test device 16 and the tested component, avoiding power interruption from affecting the test progress and ensuring the continuity and stability of the test process. The overall device adopts an integrated structural design, and the functional components work together and connect smoothly. It can realize automated and precise operation of cold start hot-plugging test, greatly reducing the operation error caused by manual intervention, improving test efficiency, and adapting to the testing needs of computer components of different specifications, with strong versatility.

[0031] Working Principle: The power supply unit 18, as the core power supply component of the entire device, is stably electrically connected to the test device 16. It can continuously provide stable and continuous power support to the test device 16 and the computer components under test during subsequent hot-swap tests, avoiding test failures or damage to the components under test due to unstable or interrupted power supply, and providing power assurance for the smooth progress of the test. The cooling component 13 is installed on one side of the test platform 1 and is connected to the calibration base 7 and the cold constant temperature chamber 3 through dedicated pipelines. It can precisely adjust the cooling power according to the test requirements and synchronously control the temperature of the calibration base 7 and the cold constant temperature chamber 3, quickly setting up a cold test environment that meets the requirements of computer cold start conditions, ensuring that the test environment is highly consistent with the low-temperature scenario in actual use. The moving platform 2 and the suspension bracket 4 are connected by a snap-fit ​​mechanism. The ball screw 14 runs through the entire moving platform 2. Driven by the drive mechanism, the ball screw 14 can achieve precise rotation, thereby driving the moving platform 2 to complete a smooth up and down movement along the suspension bracket 4. Meanwhile, the mobile platform 2 itself has several support slide rails 8 that can be adjusted laterally. Through coordinated adjustment of the vertical and horizontal directions, the cold constant temperature chamber 3 at the top of the mobile platform 2 can be accurately aligned with the calibration base 7, ensuring that the tested component in the cold constant temperature chamber 3, the calibration base 7, and the test device 16 are in the same reference position. The positioning bracket 5 is fixedly installed inside the suspension bracket 4, and the linear slide rails 15 on both sides of the bottom of its inner wall provide stable sliding support for the test device 16. The top of the test device 16 and the positioning bracket 5 adopt a snap-fit ​​design, which can achieve smooth and stable reciprocating sliding along the linear slide rails 15 to meet the displacement requirements of hot-swap operation. The laser rangefinders 17 on both sides of the testing device 16 can detect their sliding displacement along the linear slide rail 15 in real time and provide real-time feedback of the displacement data. At the same time, several ranging photoelectric sensors 12 surrounding the surface of the ranging column 11 provide auxiliary detection of the overall displacement. The two work together to complete the displacement calibration, ensuring that the testing device 16, calibration base 7, and cold constant temperature chamber 3 always maintain precise correspondence, avoiding displacement deviation from affecting the test results. The testing component 6 is movably installed inside the positioning bracket 5 and works in conjunction with the testing device 16. As an electrical component integrating a power supply plug, the testing device 16, after sliding into position, can achieve precise docking with the computer component under test in the cold constant temperature chamber 3. By reciprocating along the linear slide rail 15, the hot-plugging action under cold start conditions is completed, thereby detecting the connection reliability, power supply stability, and plugging / unplugging performance of the component under test in a cold environment, realizing a comprehensive and accurate test of the cold start hot-plugging performance of the computer component.
