[0003] A hard disk (memory) is a standard storage device used in computer systems that is hot-swappable and capable of high-speed data transmission and is widely used. The 2.5-inch memory is a standard designated by the Global Network Storage Industry Association, with the ID SFF-8201. The standard specifies the appearance and installation dimensions of a 2.5-inch hard disk. The 2.5-inch hard disk itself is hot-swappable, but ordinary hard disks are not easy to replace when installed in embedded computers. Conventional hard disk extraction boxes or hard disk replacement brackets on the market have the disadvantages of being large in size, can only be disassembled along the plug-in direction, and are not easy to fix. In addition, due to the limited size and space of embedded computers, in addition to installing a hard disk in a limited space, the entire machine also needs to be designed for electromagnetic compatibility, etc. Therefore, the hard disk extraction box or hard disk replacement bracket in the prior art is not suitable for use in embedded computers.

[0004] Based on this, the existing technology needs to be further developed. Utility Model Content

[0032] In the embedded computer for facilitating replacement of the hard disk 31 of the present embodiment, the slide rails include: a first slide rail 111, the first slide rail 111 is located at the side opposite to the first plate body 11 and the second plate body 12, and the first slide rail 111 is arranged between the operation port 112 and the PCB back plate 2; a second slide rail 121, the second slide rail 121 is located at the side opposite to the second plate body 12 and the first plate body 11, and the second slide rail 121 is arranged; the slide groove includes: a first slide groove 321, the first slide groove 321 is arranged relative to the first slide rail 111; the second slide groove 322, the second slide groove 322 is arranged relative to the second slide rail 121; the first slide groove 321 and the second slide groove 322 are respectively located at both sides of the hard disk fixing box 32.

[0033] It should be noted that when installing the hard disk 31, first fix the hard disk 31 into the hard disk fixing box 32, then make the first slide groove 321 and the second slide groove 322 of the hard disk fixing box 32 respectively engage with the first slide rail 111 and the second slide rail 121, and then push the hard disk fixing box 32 toward the PCB backplane 2 to connect the hard disk 31 to the hard disk assembly 3. The first slide rail 111 and the second slide rail 121 have the function of positioning and guiding the installation of the hard disk 31.

[0034] Specifically, a plurality of first slide rails 111 and a plurality of second slide rails 121 are provided to enable installation of a plurality of hard disks 31 .

[0035] In the embedded computer of the present embodiment which is convenient for replacing the hard disk 31, a limiting portion 323 is provided at one end of the first slide groove 321 away from the PCB back plate 2; the limiting portion 323 protrudes from the outer surface of the hard disk fixing box 32; when installing the hard disk 31, when the limiting portion 323 abuts against the end surface of the first slide rail 111, the installation of the hard disk 31 is completed.

[0036] It should be noted that, through the cooperation between the limiting portion 323 and the first slide rail 111, after the hard disk 31 is accurately connected to the hard disk assembly 3, the hard disk fixing box 32 cannot be pushed forward any further, thereby preventing damage to the hard disk assembly 3 and the hard disk 31 due to excessive force, thereby increasing the service life of the hard disk assembly 3 and the hard disk 31.

[0041] In the embedded computer of the present embodiment which is convenient for replacing the hard disk 31 , a handle 326 is provided on the side of the hard disk fixing box 32 away from the PCB back plate 2 , and the hard disk fixing box 32 can be slid on the first slide rail 111 and the second slide rail 121 by pulling the handle 326 .

[0042] When installing the hard disk 31, first, install the hard disk 31 into the hard disk fixing box 32, and tighten the knurled small head screw to achieve a stable connection between the hard disk 31 and the hard disk fixing box 32. Secondly, put the hard disk assembly 3 into the computer case 1 through the operation port 112, and make the first slide groove 321 and the second slide groove 322 of the hard disk fixing box 32 respectively engage the first slide rail 111 and the second slide rail 121. Under the guidance of the first slide rail 111 and the second slide rail 121, the hard disk fixing box 32 is pushed toward the direction close to the PCB back plate 2 through the knurled small head screw or the handle 326 until the limit portion 323 abuts against the end surface of the first slide rail 111 and the hard disk fixing box 32 cannot be pushed further toward the direction close to the PCB back plate 2. At this time, the spring washer 327 and the flat washer 328 are put on the loose screw, and the loose screw is passed through the threaded through hole and tightened with the hard disk fixing box 32; finally, the detachable panel 113 is installed to the operation port 112 to complete the operation of installing the hard disk 31 on the embedded computer.

[0043] When removing the hard disk 31, first, remove the removable panel 113 from the operating port 112, and remove the captive screws to completely detach the captive screws from the hard disk fixing box 32; secondly, grasp the knurled small head screw or the handle 326 to pull the hard disk assembly 3 to the appropriate position and then remove it from the operating port 112 to complete the operation of removing the hard disk 31 of the embedded computer.

[0044] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
