Consisting of a housing, a control unit, and storage units (FLASH and DRAM chips), SSDs undergo performance testing after production. Stress testing is a key method for assessing SSD quality, primarily to determine whether the SSD possesses sufficient resistance to deformation.

[0003] Publication No. CN221124096U discloses a solid-state hard disk stress test device, comprising a test box, a control box, a test bench disposed within the test box, a compression device disposed on the top of the test box and directly above the test bench, a deformation trigger switch disposed at the center of the test bench, and a deformation detection device disposed within the test box; the control box is provided with a deformation trigger warning light and a deformation detection light, the deformation trigger switch being connected to the deformation trigger warning light; the deformation detection device comprises a horizontal moving device and one or more conductive test pins disposed on the horizontal moving device; the control box is connected to the horizontal moving device and the compression device respectively; the deformation detection light is electrically connected to the conductive test pins; the test bench is provided with two clamping platforms, the two clamping platforms being disposed opposite each other, and the deformation trigger switch being located between the two clamping platforms. Although this stress test device cooperates with the deformation trigger switch and the deformation trigger warning light, after the solid-state hard disk is squeezed by the compression device, by checking whether the deformation trigger warning light is illuminated, it is possible to quickly and intuitively determine whether the solid-state hard disk as a whole has been bent. However, this type of stress testing device, with its fixed test points, lacks flexibility and cannot perform fixed-point or multi-point stress testing based on different testing requirements or the specific structural characteristics of different hard drives. This fixed nature limits the comprehensiveness and applicability of the test, making it impossible to effectively simulate the various physical stress conditions that hard drives may encounter in actual use. Therefore, improvements are needed. Utility Model Content

[0023] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0024] Please refer to Figure 1-Figure 5The present invention provides a solid-state hard drive stress testing device, comprising a base 1, a support frame 2 fixedly mounted on the top surface of the base 1, and a hydraulic cylinder 3 fixedly mounted on the top surface of the support frame 2. The hydraulic cylinder 3 drives a pressure plate 4 downward to perform pressure testing on the hard drive body 7. The pressure plate 4 is mounted on the output end of the hydraulic cylinder 3. This connection is typically bolted or welded, ensuring stable pressure transmission and the reliability of the pressure plate 4. A placement table 5 is fixedly mounted on the top surface of the base 1. A slot 6 is defined on the top surface of the placement table 5, and a hard drive body 7 is placed inside the slot 6. The hard drive body 7 is placed in the slot 6 and is pressed downward by the pressure plate 4 to test the structural strength of the hard drive body 7. The bottom surface of the pressure plate 4 defines a slot 8, to the inner wall of which an insert 9 is slidably connected. Both the slot 8 and the insert 9 are T-shaped. This sliding connection allows the insert 9 to move up and down within the slot 8, but restricts movement in other directions, thereby ensuring the accuracy of the test. A compression pad 10 is fixedly mounted on the bottom surface of the insert block 9 and is bolted or welded to the insert block 9, providing the necessary stability and durability. A rod 11 is inserted into the top surface of the pressure plate 4, and a top plate 13 is fixedly mounted on the top of the rod 11. A handle 17 is fixedly mounted on the top surface of the top plate 13. The handle 17 is made of PP plastic and provides a lightweight and durable operating handle.

[0025] The top plate 13 is slidably connected to the vertical plate 14. A top block 15 is fixedly mounted on the top of the vertical plate 14, and a spring 16 is sleeved on the surface of the vertical plate 14. One end of the spring 16 is fixedly connected to the top block 15, and the other end is fixedly connected to the top plate 13. This design allows the top plate 13 to move downward under the action of the spring 16, driving the insertion rod 11 to insert into the socket 12, thereby limiting the compression pad 10. This design improves operational flexibility and the adaptability of the equipment. A deformation trigger switch 22 is fixedly mounted on the top surface of the base 1, and a deformation trigger warning light 23 is fixedly mounted on the side of the support frame 2. When the hard disk body 7 is deformed due to force to trigger the deformation trigger switch 22, the deformation trigger warning light 23 will be illuminated, reminding the operator that the hard disk has reached the preset deformation threshold. At this time, the pressure plate 4 can be released to observe whether the hard disk body 7 has left the deformation trigger switch 22, thereby determining whether the hard disk body 7 has recovered.

[0026] The bottom surface of the compression pad 10 is equipped with a concentrated stress testing mechanism. This mechanism includes circular holes 18, which are evenly spaced. Magnets 19 are fixedly mounted on the inner walls of the circular holes 18. Short rods 20 made of ferritic stainless steel are also mounted on the inner walls of the circular holes 18. The circular holes 18 are sized to accommodate the short rods 20, and a metal block 21 is fixedly mounted at the bottom end of the short rods 20. This configuration allows the magnets 19 to attract the short rods 20, keeping the metal block 21 stably fixed within the circular holes 18, thereby simulating the situation of a hard object squeezing the hard disk body 7 during the pressure test. This design improves the practicality and applicability of the test while increasing its flexibility, making the entire testing process more efficient and convenient. The metal blocks 21 enable a hard squeeze test on the surface of the hard disk body 7, simulating a solid object squeezing the hard disk body 7. Workers can also install multiple metal blocks 21 depending on the desired location for the squeeze test. When removing the metal block 21 , the worker only needs to pull the metal block 21 outward, and the metal block 21 can then drive the short rod 20 to leave the circular hole 18 , thereby facilitating operation and maintenance.

[0027] In this embodiment, the pressure plate 4 can be driven to move downward by the hydraulic cylinder 3. At this time, the hard disk body 7 is placed in the card slot 6, and then the hard disk body 7 can be squeezed downward by the pressure plate 4. At this time, the hard disk body 7 can be tested, and when the hard disk body 7 is deformed to the point of squeezing the deformation trigger switch 22, the deformation trigger warning light 23 can be lit. Then, when the pressure plate 4 is released, it is observed whether the hard disk body 7 leaves the deformation trigger switch 22 to determine whether the hard disk body 7 is restored. At the same time, during the test, the staff can insert the plug 9 into the slot 8. Then, due to the elastic force of the spring 16, the spring 16 can drive the top plate 13 to move downward, and the top plate 13 can then drive the insertion rod 11 to insert the insertion rod. The hole 12 is formed, and the squeeze pad 10 can be limited at this time. The squeeze pad 10 can be set to perform stress testing on a certain position on the surface of the hard disk body 7. At the same time, multiple slots 8 can be equipped with multiple squeeze pads 10, so that stress testing can be conveniently performed on multiple positions on the surface of the hard disk body 7. The utility model can flexibly set the position of the squeeze pad 10 through the design of the plug block 9 and the slot 8, combined with the top plate 13 driven by the spring 16 and the plug rod 11 mechanism, so as to realize stress testing on multiple specific positions on the surface of the hard disk body 7. This design enables the device to perform fixed-point or multi-point pressure testing on different positions according to the test requirements, thereby improving the comprehensiveness and applicability of the test, and using multiple slots 8 and squeeze pads 10 can greatly improve the safety of the hard disk body 7. The combination is convenient for testers to adjust the distribution and number of test points according to their needs, which increases the flexibility of the test and makes the entire test process more efficient and convenient. The metal block 21 provided can perform a hard extrusion test on the surface of the hard disk body 7, simulating a solid hard object squeezing the hard disk body 7. At the same time, the staff can also install multiple metal blocks 21 according to the location of the extrusion test as needed, and when removing the metal block 21, the staff only needs to pull the metal block 21 outward, and the metal block 21 can then drive the short rod 20 to leave the round hole 18. The utility model uses the metal block 21 to perform hard extrusion on the hard disk body 7, which can simulate extreme situations that may be encountered in actual use, such as object collision or high pressure. The impact of the environment on the hard disk. This test can better evaluate the durability and stability of the hard disk when it is hit by hard objects. At the same time, multiple metal blocks 21 can be installed on the test bench as needed, so that the test device can perform stress tests on different positions of the hard disk simultaneously or separately. This design improves the flexibility and coverage of the test, allowing staff to customize the layout of pressure points according to test requirements and more comprehensively evaluate the structural strength of the hard disk. The metal block 21 is designed to be easy to install and disassemble. The staff can easily replace it by simply pulling it outward, which not only simplifies the testing process, but also speeds up the configuration and reset time of the test equipment. This quick replacement mechanism is particularly suitable for high-efficiency production line testing and quality control.

[0028] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
