[0033] See also Figures 1 to 8The utility model discloses a device for hard disk test, including: mount 10, fixed component 20 and heat dissipation component 30, fixed component 20 swing joint in mount 10, and fixed component 20 is used to install hard disk, heat dissipation component 30 installs in the top or side of mount 10 to provide heat dissipation for hard disk, fixed component 20 includes upper module 21 and with the lower module 22 of same structure of upper module 21, upper module 21 and lower module 22 are connected to the upper end and lower end of hard disk respectively, upper module 21 includes fixed plate 211, first fixed part 212 and second fixed part 213, fixed plate 211 swing joint in mount 10, fixed plate 211 is equipped with slide rail 2111, first fixed part 212 and second fixed part 213 slide connection in slide rail 2111, first fixed part 212 and second fixed part 213 combination to form the area for installing hard disk.
[0034] Specifically, by setting fixed component 20, it can be used for multiple hard disk parallel test placement, that is, multiple hard disks can be tested simultaneously, thereby improving test efficiency, which is particularly important for scenarios that require a large number of hard disk tests, such as hard disk manufacturers' quality detection, hard disk repair centers, etc. In addition, by setting heat dissipation component 30 at the end of the hard disk, the problem of poor heat dissipation of the hard disk during testing is solved, and the test accuracy is improved. That is, heat dissipation component 30 obtains the hard disk temperature from the server through network port 34 and automatically adjusts the speed of fan module 33 to keep the hard disk temperature within the preset range. This precise temperature control helps to ensure the accuracy and consistency of the test, avoids the impact of temperature fluctuations on the test results, and also solves the problem of temperature adjustment and control in PCBA disk testing, power consumption testing, UBER, MTBF, environmental climate testing without shell protection. In addition, the design of the device has a certain flexibility, which can be adjusted according to different test requirements and hard disk specifications. For example, by adjusting the position of fixed plate 211 on mount 10 and the position of first fixed part 212 and second fixed part 213 on slide rail 2111, different sizes of hard disks can be adapted. This flexibility makes the device suitable for a variety of test scenarios and hard disk types.
[0035] More specifically, in this embodiment, heat dissipation component 30 is installed on the top of mount 10, that is, blowing heat dissipation is performed on the hard disk from above. In other embodiments, heat dissipation component 30 can be installed on the side of mount 10, that is, blowing heat dissipation is performed on the hard disk from the side to adapt to different test scenarios. Fixed plate 211 is provided with a plurality of slide rails 2111, and the number of first fixed part 212 and second fixed part 213 corresponds to the number of slide rails 2111, which is not limited here.
[0036] Reference Figures 1 to 5As shown, in one embodiment, the first fixing member 212 is provided with a U-shaped groove 2121, and the second fixing member 213 is provided with a single-sided open U-shaped groove 2131, and the U-shaped groove 2121 and the single-sided open U-shaped groove 2131 are combined to form an area for installing the hard disk.
[0037] Specifically, the interior and exterior of the U-shaped groove 2121 and the single-sided U-shaped groove 2131 are made of an insulating material, and the inner diameter of the opening matches the thickness of the hard drive being tested. In other words, the design of the U-shaped groove 2121 and the single-sided U-shaped groove 2131, with the inner diameter of the opening matching the thickness of the hard drive being tested, ensures that the hard drive can be tightly and stably mounted in the fixing assembly 20. This precise fit helps reduce the hard drive's shaking and displacement during testing, thereby improving the accuracy and stability of the test. Furthermore, the design of the U-shaped groove 2121 and the single-sided U-shaped groove 2131 makes it easier to insert and remove the hard drive, without the need for complex operations or tools. This not only improves testing efficiency but also reduces operational difficulty and labor costs. Furthermore, the interior and exterior of the U-shaped groove 2121 and the single-sided U-shaped groove 2131 are made of an insulating material, which helps prevent damage to the hard drive due to static electricity or electrical interference during testing. The use of insulating materials improves the safety of the test and protects the integrity and performance of the hard drive. In addition, the insulating material can also reduce the electromagnetic interference between the hard disk and the fixed component 20, ensuring the accuracy and reliability of the test results, which is particularly important for hard disk testing that requires high-precision measurements. In addition, the combined design of the U-shaped groove 2121 and the single-sided open U-shaped groove 2131 allows the fixed component 20 to have a certain degree of flexibility. This flexibility helps to make fine adjustments as needed during the test to ensure the optimal installation position and stability of the hard disk. In addition, although the inner diameter of the opening of the U-shaped groove 2121 and the single-sided open U-shaped groove 2131 is consistent with a hard disk of a specific thickness, this design can be customized or adjusted for hard disks of different thicknesses. By replacing fixings of different sizes, the device can adapt to the testing needs of hard disks of various specifications.
[0038] In other embodiments, the first fixing member 212 and the second fixing member 213 may also be movable clips for clamping the hard disk.
[0039] See also Figures 1 to 5 As shown, in one embodiment, the first fixing member 212 and the second fixing member 213 are both slidably connected to the slide rail 2111 via an adjusting bolt 214 .
[0040] Specifically, adjustment bolt 214 passes through slide rail 2111 and connects to first fixing member 212 or second fixing member 213. Moving adjustment bolt 214 adjusts the distance between first fixing member 212 and second fixing member 213. This fine-tuning capability allows the hard drive to be accurately installed in the predetermined position, ensuring the hard drive's stability during testing. Furthermore, thanks to the presence of adjustment bolt 214, fixing assembly 20 can accommodate hard drives of varying lengths. By adjusting the position of adjustment bolt 214, the hard drive can be securely secured within fixing assembly 20, preventing shaking or displacement from affecting test results.
[0041] See also Figures 1 to 4 As shown, in one embodiment, the four corners of the fixing plate 211 are provided with guide blocks 2112 , and the mounting frame 10 is provided with guide rails 11 corresponding to the guide blocks 2112 .
[0042] Specifically, the cooperation between the guide blocks 2112 and the guide rails 11 allows for convenient adjustment of the positions of the two fixing plates 211 on the mounting frame 10. This adjustability allows the device to accommodate hard drives of varying widths without requiring replacement or adjustment of other components, thereby enhancing the device's versatility and flexibility. Furthermore, by being able to accommodate hard drives of varying widths, this design enables the test device to test a wider variety of hard drives, expanding its testing scope. This is particularly important for hard drive manufacturers, repair centers, research institutions, and other organizations that need to test a variety of hard drive specifications.
[0043] See also Figures 1 to 2 As shown, in one embodiment, the heat dissipation assembly 30 includes a support plate 31, a support arm 32 and a fan module 33, the fan module 33 is installed on the support plate 31, the support plate 31 is located at the top or side of the mounting frame 10, one end of the support arm 32 is connected to the support plate 31, and the other end is connected to the mounting frame 10.
[0044] Specifically, the mounting frame 10 is provided with mounting holes corresponding to the support arms 32 in both the vertical and horizontal directions, so that the support plate 31 can be installed on the top or side of the mounting frame 10 through the support arms 32, so that the fan module 33 can dissipate heat from the hard disk in different directions, expanding the application scenarios of hard disk testing. In addition, as the core component of the heat dissipation assembly 30, the fan module 33 generates airflow through rotation, accelerates air flow, and thus takes away the heat generated by the hard disk test, which helps prevent the hard disk from overheating and ensures the accuracy of the test. In addition, the support plate 31 not only provides a mounting base for the fan module 33, but also plays a role in supporting and stabilizing the entire heat dissipation assembly 30, which ensures that the fan module 33 will not affect the heat dissipation effect due to vibration or shaking during operation.
[0045] See also Figures 1 to 2As shown, in an embodiment, the side of the support plate 31 is also provided with a network port 34, which is electrically connected to the fan module 33.
[0046] Specifically, the network port 34 adopts an RJ-45 interface and is connected to a server network to obtain the real-time temperature of the hard disk, which is used to adjust the rotating speed of the fan module 33 so as to accurately control the hard disk temperature within the set disk temperature ± 2℃ range. That is, by connecting to the server network through the network port 34, the working temperature of the hard disk can be obtained in real time. This real-time monitoring capability enables the system to respond quickly to temperature changes, so as to take appropriate heat dissipation measures. In addition, according to the real-time temperature data, the system can accurately control the rotating speed of the fan module 33 to achieve the purpose of controlling the hard disk temperature. This accurate adjustment capability helps to ensure that the hard disk temperature is within the set disk temperature ± 2℃ range, thereby improving the test accuracy. In addition, by accurately controlling the hard disk temperature, the interference of temperature on the test results of the hard disk can be reduced, which helps to improve the accuracy and reliability of the test, so that the test results are closer to the performance in the actual use scenario. In addition, a stable temperature environment helps to optimize the hard disk test environment, so that the test results are more consistent and predictable, which is particularly important for hard disk manufacturers, maintenance centers or research institutions that need to conduct a large number of hard disk tests.
[0047] Referring to Figures 1 to 2 As shown, in an embodiment, the side of the support plate 31 is also provided with a power interface 35, which is electrically connected to the fan module 33.
[0048] Specifically, the power interface 35 is used to provide power for the fan module 33, which adopts an IEC60320 C13 female head. That is, the main function of the power interface 35 is to connect the power cord to provide stable power supply for the fan module 33, which is the basis for the normal operation of the fan module 33 and the premise of realizing the heat dissipation function. In addition, the IEC60320 C13 female head is used as the power interface 35, which ensures the compatibility with the standard power cord. This interface design has been widely recognized and used internationally, which is convenient for users to replace or repair the power cord.
[0049] More specifically, the fan module 33 includes a plurality of fans, and the specific number is not limited here.
[0050] Referring to Figures 1 to 2 and Figures 6 and 7As shown, in one embodiment, one side of the mounting frame 10 is further provided with an interface component 40 corresponding to the fixing component 20, and the interface component 40 includes a connecting column 41 and a cover plate 42, and the connecting column 41 is provided with a placement groove 411 and a wire hole 412, and the wire hole 412 is connected to the placement groove 411, and the cover plate 42 is connected to the connecting column 41 and is used to cover the placement groove 411, and the placement groove 411 is used to place a signal line interface (not shown in the figure), one end of the signal line interface is electrically connected to the hard disk, and the other end is connected to a signal line (not shown in the figure), and the signal line passes through the wire hole 412 and is connected to the external host.
[0051] Specifically, the design of the placement slot 411 provides a fixed storage space for the signal line interface, so that the signal line interface is fixed, which can ensure a stable connection between the signal line interface and the hard disk, so as to avoid the situation where the test accuracy is affected by an unstable connection. In addition, the wire hole 412 is connected to the placement slot 411, so that the signal line can easily pass through the connecting column 41 and be connected to the external host. This design avoids the signal line from being in disarray on the mounting frame 10, and improves the neatness and aesthetics of the device. In addition, one end of the signal line interface is electrically connected to the hard disk, and the other end is connected to the external host through a signal line. This connection method ensures that the signal transmission between the hard disk and the external host is stable and reliable, and provides a strong guarantee for reading and writing data.
[0052] More specifically, the number of interface assemblies 40 corresponds to the number of slide rails 2111 and is not limited here.
[0053] In one embodiment, the connection post 41 may be an outer insulating metal component integral with the mounting bracket 10 ; or an independent outer insulating metal component, which is then fixed to the mounting bracket 10 by bolts.
[0054] Specifically, when the connecting column 41 is an outer insulating metal component that is integrated with the mounting frame 10, the connection between them is more secure and less likely to loosen or fall off. This design helps to improve the stability and safety of the entire structure. In addition, for independent outer insulating metal components, fixing them to the mounting frame 10 with bolts can ensure that the connection between the connecting column 41 and the mounting frame 10 is tight and reliable. The bolt fixing method has high shear and tensile resistance and can withstand large external forces, thereby ensuring the stability and safety of the structure. In addition, the outer insulating metal component can play a role in shielding electromagnetic interference and protect the signal line interface from interference and influence of external electromagnetic waves, which helps to improve electromagnetic compatibility and ensure the normal progress of the test.
[0055] In one embodiment, the outer surface of the cover plate 42 is flush with the connecting post 41 .
[0056] Specifically, the cover plate 42 is fixed to the connecting post 41 via screws, and the outer surface of the cover plate 42 is flush with the connecting post 41. The use of screws to secure the cover plate 42 to the connecting post 41 ensures a secure and reliable connection between the cover plate 42 and the connecting post 41, making it less likely to loosen or fall off. This fixing method can withstand certain external forces and maintain structural stability. Furthermore, the outer surface of the cover plate 42 is flush with the connecting post 41, making the entire structure more neat and aesthetically pleasing. This design avoids the cover plate 42 protruding or recessed, reducing visual interference and discomfort.
[0057] See also Figures 1 to 2 As shown, in one embodiment, the bottom of the mounting frame 10 is further connected to a base 50 .
[0058] Specifically, the base 50 serves as a connecting component between the mounting frame 10 and the ground or other infrastructure. Its primary function is to enhance the stability of the mounting frame 10. By fixing the base 50, the mounting frame 10 can be more firmly installed in the desired position, avoiding safety problems caused by shaking or tilting of the mounting frame 10.
[0059] In one embodiment, the base 50 is a flat plate, or is provided with four columns for connection with the mounting bracket 10 .
[0060] Specifically, the flat plate, through its wide contact area, provides stable and uniform support for the mounting frame 10. This design helps distribute the pressure of the mounting frame 10 on the ground or underlying structure, preventing localized overloads that could damage the ground or cause the mounting frame 10 to tilt. The columnar base 50 is connected to the ground or underlying structure via four columns, providing four stable support points for the mounting frame 10. This design helps enhance the mounting frame 10's resistance to overturning and torsional torsion.
[0061] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
