Description

Technical Field

[0001] This utility model relates to the field of hard disk testing technology, and in particular to a hard disk testing device. Background Technology

[0002] As one of the main storage media in computers, the hard drive plays a crucial role in storing large amounts of data. With the widespread use of computers and other electronic products, the importance of hard drives has become increasingly prominent. To ensure data security and integrity, hard drive maintenance is paramount. Comprehensive and precise testing is required at every stage of hard drive production, repair, and performance evaluation.

[0003] Chinese patent CN219303012U discloses a hard drive testing device that features multiple hard drive slots and corresponding motherboard partitions, enabling simultaneous testing of multiple hard drives with high efficiency. It also displays the parameters of the tested hard drives on a screen, allowing users to switch the display to show the corresponding parameters via a toggle button, providing strong interactivity and ease of use. An external power supply is connected via a power interface for convenient power supply replacement.

[0004] The aforementioned testing device has several shortcomings. During testing, especially under full load, the hard drive generates a significant amount of heat, causing its temperature to rise rapidly. Once the hard drive temperature exceeds its normal operating range, its built-in overheat protection mechanism automatically reduces read and write speeds. This not only affects the hard drive's normal performance but also leads to inaccurate test results, failing to accurately reflect the hard drive's actual performance and severely reducing the accuracy and reliability of the test. Furthermore, the existing device lacks a guiding structure when inserting the hard drive into the testing device's interface, making it difficult for operators to precisely align the hard drive. This not only increases the difficulty of operation but also wastes considerable time due to repeated insertion attempts, reducing the efficiency of hard drive testing. Utility Model Content

[0031] Please see Figure 1-5 This utility model provides a hard disk testing device, comprising:

[0032] The chassis 1 has a first partition 11 and a second partition 12 fixedly installed inside it;

[0033] Multiple test benches 2 are fixedly installed between one side inner wall of the chassis 1 and the first partition 11. A heat insulation shell 21 is fixedly connected to the lower side wall of the test bench 2. A heat conduction plate 22 is fixedly embedded on the test bench 2. Heat dissipation fins 23 are installed on the lower side wall of the heat conduction plate 22.

[0034] Multiple hard drive interfaces 3 are installed on the rear inner wall of the chassis 1;

[0035] Multiple mounting plates 4 are fixedly mounted on one side wall of the second partition 12. A motherboard 41 is provided on the upper side wall of the mounting plate 4, and the hard disk interface 3 is electrically connected to the motherboard 41.

[0036] Water cooling component 5 is installed on chassis 1 and is used to cool the hard drive during testing.

[0037] Guide component 6 is mounted on chassis 1. Guide component 6 is used to guide the hard drive to be tested so that it is accurately inserted into hard drive interface 3.

[0038] By setting up the above structure, hard drive testing was achieved, and the accuracy and reliability of the test results were improved.

[0039] The water-cooling assembly 5 includes a liquid storage tank 51 and a circulation pump 52 fixedly mounted on the upper outer wall of the chassis 1. The inlet of the circulation pump 52 is connected to the liquid storage tank 51 through an inlet pipe. A heat exchange tube 53 is embedded in the heat dissipation fins 23. A diversion pipe 54 is fixedly mounted on one side outer wall of the chassis 1. One end of the diversion pipe 54 is connected to the outlet of the circulation pump 52. Multiple first connecting pipes 55 are connected to the diversion pipe 54. The other end of the first connecting pipe 55 is connected to one end of the heat exchange tube 53. A manifold 56 is fixedly mounted on one side wall of the first partition 11. Multiple second connecting pipes 57 are connected to the manifold 56. The other end of the second connecting pipe 57 is connected to the other end of the heat exchange tube 53. One end of the manifold 56 is connected to the liquid storage tank 51.

[0040] With the above structure, the circulating coolant carries away the heat from the heat sink fins 23, achieving continuous and efficient heat dissipation of the hard drive during the test. This avoids the problem of the hard drive automatically reducing its read and write speed due to high temperature, ensuring that the hard drive maintains normal performance throughout the test.

[0041] The guide assembly 6 includes two housings 61, which are fixedly mounted on one outer wall of the chassis 1 and one side wall of the first partition 11, respectively. A movable block 62 is slidably mounted inside the housing 61. A screw 63 is rotatably mounted on one inner wall of the housing 61. The other end of the screw 63 is threaded through the movable block 62 and extends to the outside of the housing 61 and is fixedly connected to an adjustment knob 64. Guide grooves 611 are provided on both the upper and lower side walls of the housing 61. A follower plate 65 is slidably mounted inside the guide groove 611. The follower plate 65 is fixedly connected to the movable block 62. Two side plates 67 are provided on the upper side wall of the test platform 2. Multiple guide rubber wheels 68 are provided on the side wall of the two side plates 67 that are close to each other. The follower plate 65 and the side plate 67 are fixedly connected to each other by a connecting rod 66.

[0042] The above-described structure provides precise guidance for hard drive insertion, ensuring accurate alignment of the hard drive with the interface, reducing operational difficulty, minimizing time wasted due to insertion difficulties, and improving testing efficiency.

[0043] A radiator 511 is installed on the upper side wall of the liquid storage tank 51.

[0044] With the above-described structure, the coolant in the reservoir 51 can be cooled. The radiator 511 is a mature existing technology that dissipates the heat of the coolant in a timely manner through heat transfer. Therefore, its specific structure will not be described in detail here.

[0045] A cooling fan 7 is installed on the other side wall of the chassis 1.

[0046] The above structure allows the heat generated by the motherboard 41 to be expelled from the chassis 1.

[0047] The front outer wall of chassis 1 is equipped with a display screen and a switching button is located below the display screen.

[0048] With the above-described structure, the display screen can show the hard drive test parameters interface, and the switch button can be used to display test parameters for different hard drives.

[0049] It should be noted that the display screen and the switching button have been used in Chinese patent CN219303012U and are common prior art in this field, so they will not be described again in this article.

[0050] The heat-conducting plate 22 is made of copper or aluminum, which ensures the heat exchange efficiency of the heat-conducting plate 22 and promptly transfers the heat of the hard drive to the heat dissipation fins 23.

[0051] It should be noted that this utility model is a hard drive testing device. In use, the hard drive is placed on the test platform 2 and then pushed. During this pushing process, the guide rubber wheels 68 on the two side plates 67 guide the hard drive to accurately insert into the hard drive interface 3. Then, the motherboard 41 tests the hard drive inserted into the hard drive interface 3, and the test data is displayed on the screen. During the test, the heat generated by the hard drive is conducted to the heat conduction plate 22, and then to the heat dissipation fins 23. The circulation pump 52 can draw coolant from the reservoir 51 and deliver it to the distribution pipe 54. Then, the coolant enters the heat exchange pipe 53 through each of the first connecting pipes 55. As the coolant flows through the heat exchange pipe 53, it absorbs heat, and then enters the collector pipe 56 through the second connecting pipe 57. Under water pressure, the coolant flows back into the reservoir 51. The radiator 511 continuously dissipates heat from the coolant in the reservoir 51, ensuring stable heat exchange. When the specifications of the hard drive to be tested change, insert a hard drive into the hard drive interface 3, and then turn the adjustment knob 64 to drive the screw 63 to rotate. When the screw 63 rotates, it can cause the moving block 62 to move the follower plate 65. When the follower plate 65 moves, it pushes each side plate 67 to move through the connecting rod 66, thereby changing the position of the guide rubber wheel 68, so that the guide rubber wheel 68 on one side of the hard drive fits against the side of the hard drive. Then, turn another adjustment knob 64 in the same way so that the guide rubber wheel 68 on the other side of the hard drive also fits against the other side of the hard drive. At this time, other hard drives of the same specifications can be directly and accurately connected when plugged into the hard drive interface 3.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
