[0002] With the development of China's electronic technology, electronic equipment has been widely used. As an important component of electronic equipment, servers are responsible for responding to service requests, providing services, and guaranteeing services. They need to run for a long time, and data security and reliability are extremely important. The hard disk is one of the most important storage devices in the server. Most of the software required for the normal operation of the server is stored on the hard disk. Therefore, the hard disk must have reliability, scalability, ease of use, easy maintenance and manageability.

[0003] Since hard disk data is stored, maintained, expanded, and replaced frequently, in order to facilitate maintenance, expansion, and replacement of hard disks by computer room maintenance personnel, hard disks are generally installed detachably through hard disk trays.

[0004] The installation of hard disks and trays on the market is generally done by fixing the hard disk on the tray with two screws. During the disassembly and assembly process, a screwdriver is needed to screw in (install) or out (disassemble) the screws on the left and right sides of the hard disk in turn. Due to the large number of screws locking the hard disk in the entire hard disk array and their small size, maintenance personnel are prone to lose the screws during on-site disassembly and assembly, making the work extremely inconvenient. In addition, the installation positions and directions of the screws are not the same, making disassembly and assembly of the hard disk very time-consuming and labor-intensive, and the disassembly and assembly efficiency is low, resulting in increased labor costs for disassembly and assembly of the hard disk.

[0005] The existing hard disk tray structure has a complex manufacturing process, an increased number of assembly steps, a complex assembly process, and increased manufacturing costs. In addition, during transportation of the product, low-frequency vibrations may cause the shaft to loosen from the hard disk tray and the lock bolt, resulting in low reliability.

[0037] In order to make the purpose, technical solution and advantages of the utility model more clear, the following is a further detailed description of a tool-free hard disk tray of the utility model in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0038] Please refer to Figure 1-Figure 8 , a tool-free hard disk tray, comprising:

[0039] The tray body 100 includes a bottom support plate 110, two side plates 120 and a front end seat 140. A side plate 120 is connected to each of the two sides of the bottom support plate 110. The front end seat 140 is connected to one end of the two. The bottom support plate 110, the two side plates 120 and the front end seat 140 form a hard disk 300 receiving groove 160. The front end seat 140 has a first boss 141 protruding toward the hard disk 300 receiving groove 160. The first boss 141 is adapted to the front end screw hole 310 of the hard disk 300.

[0040] The elastic lock 200 includes an elastic plate 210, a second boss 211 arranged on the elastic plate 210, and a hook 230 arranged on the elastic plate 210 near the bottom support plate 110. One end of each side plate 120 away from the front end seat 140 is hinged to an elastic lock 200. The side plate 120 has a avoidance notch for the second boss 211 to extend into the hard disk 300 accommodating groove 160. The second boss 211 is adapted to the rear side screw hole 320 of the hard disk 300. The bottom support plate 110 is provided with a slot or hole 111 adapted to the hook 230.

[0041] The first boss 141 of the front seat 140 corresponds to the front screw hole 310 of the hard disk 300, which can ensure that the hard disk 300 is fixed and stable, and can also ensure that the indicator light 330, the jack and other positions at the front of the hard disk 300 correspond accurately to the front seat 140; the second boss 211 on the elastic lock buckle 200 corresponds to the rear screw hole 320 of the hard disk 300 by using the elastic deformation characteristics, and the hard disk 300 is limited in the hard disk 300 accommodating slot 160. The use of bosses to replace traditional screws makes it convenient, simple, time-saving and labor-saving to install the hard disk 300, eliminating the need for installation screws and tools, reducing costs and improving assembly time. In addition, the elastic properties of the elastic lock plate and the elastic properties of the first boss 141 are utilized. During the transportation of the product, low-frequency or high-frequency vibration will not cause the lock buckle to loosen from the hard disk 300 tray installation column, and the reliability is increased. The setting of the bottom support plate 110 strengthens the structural force support, and the overall structural reliability of the tray assembly is greatly enhanced.

[0042] Please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 The side plate 120 is provided with a hinge column 130 at one end away from the front seat 140. The hinge column 130 has a rotation limiter 131 formed by a protrusion. The elastic lock buckle 200 has a hinge tube 220. The hinge tube 220 has a slot 221. The rotation limiter 131 is located in the slot 221 to limit the rotation angle of the elastic lock buckle 200. The elastic lock buckle 200 is easily damaged by a large angle rotation. The rotation limiter 131 is provided to limit the rotation angle of the elastic lock buckle 200, which can effectively prevent the elastic lock buckle 200 from getting stuck and protect the various parts of the tray from being damaged. Preferably, the rotation angle limited by the slot 221 and the rotation limiter 131 is 20-50°, especially 30°.

[0043] Please refer to Figure 2 The hinge column 130 is sleeved with a gasket 132, which abuts against the end surface of the hinge cylinder 220. This prevents the tray and the left and right lock buckles from getting stuck due to manufacturing dimensional accuracy, assembly dimensional tolerance, and shape and position tolerance, and ensures the smooth rotation of the left and right lock buckles.

[0044] Please refer to Figure 7, the hinged column 130 and the hinged tube 220 bulge inwardly into the hard disk 300 receiving groove 160 to form a safety blocking portion 150. The safety blocking portion 150 is provided to block the hard disk 300. Even if the second protruding column 211 is broken, the safety blocking portion 150 can still block the hard disk 300 to prevent the hard disk 300 from falling, and the hard disk 300 connected to the tool-free hard disk 300 tray of the present application can be taken out as a whole, and then the elastic lock 200 can be re-engaged to facilitate maintenance and repair. During assembly, the elasticity of the side panel 120 and the hinged column 130 itself can be used for assembly, or an inclined angle can be used for assembly, such as tilting 15° to first align the front screw hole 310 of the hard disk 300 with the first protruding column 141, and then the rear end is inserted into the hard disk 300 receiving groove 160, and then locked by the elastic lock 200.

[0045] Please refer to Figure 8 , a foolproof portion 212 is provided on one side of the two side panels 120 facing away from the hard disk 300 receiving slot 160 or one side of the two elastic plates 210 facing away from the hard disk 300 receiving slot 160. The foolproof portion 212 can be a protrusion or a groove to prevent reverse installation. A novice user or a non-professional user can easily insert the hard disk 300 tray in the reverse direction, effectively protecting the hard disk 300 gold finger from being damaged by the hard disk 300 backplane connector, the hard disk 300 backplane connector from being damaged by the hard disk 300 gold finger, or preventing the hard disk 300 gold finger from damaging the electronic components on the hard disk 300 backplane, thereby improving the assembly safety and reliability of the whole hard disk 300.

[0046] Please refer to Figure 2 , Figure 7 and Figure 8 A pair of elastic arch bridges 121 are respectively provided at both ends of the side of the side panel 120 facing away from the hard disk 300 receiving slot 160. Each pair has two elastic arch bridges 121 spaced apart from each other and arched away from each other. The elastic arch bridges 121 are used to cooperate with the guide rail. When there is a gap 170 between the hard disk 300 tray module and the installation guide rail, the elastic arch bridge 121 fills the gap 170 to ensure that the hard disk 300 tray is in good contact with the guide rail in both the up and down and left and right directions, and the hard disk 300 tray can be plugged in and out smoothly; at the same time, when the product is transported in a vibration environment, the entire module will not shake up and down or make abnormal sounds due to the elastic deformation of the plastic arch bridge of the tray, thereby ensuring the assembly reliability of the hard disk 300 and the back panel. Preferably, the elastic arch bridges 121 at the upper and lower ends are positioned correspondingly, are arranged in pairs, and arched away from each other; the elastic arch bridges 121 are particularly symmetrically arranged, that is, the elastic arch bridges 121 on the left and right side panels 120 are symmetrically arranged. It can be understood that the side panel 120 is generally made of plastic or metal (aluminum alloy, stainless steel, etc.), which itself has a certain elasticity. The elasticity is enhanced by arching so that the elastic arch bridge 121 can be deformed.

[0047] Please refer to Figure 2 and Figure 8 The bottom support plate 110 is provided with a plurality of heat dissipation holes 113. This can be beneficial to the heat dissipation of the hard disk 300 and can reduce the weight of the tray assembly. Preferably, the heat dissipation holes 113 are arranged in an array.

[0048] Please refer to Figure 8 The bottom support plate 110 has a slot or hole 111 that matches the hook 230 and extends to have a hand buckle space 112. The hand buckle space 112 is provided to facilitate opening the elastic lock 200.

[0049] Please refer to Figure 7 There is a gap 170 between the bottom support plate 110 and the front end seat 140. The setting of the gap 170 facilitates the installation of the hard disk 300. During installation, the front end of the hard disk 300 can be tilted and aligned with the first protrusion 141, and then snapped into the second protrusion 211.

[0050] Please refer to Figure 1 The front seat 140 has a connecting spring and a clearance hole for the hard disk indicator light 330 to pass through. It is convenient to connect the spring and convenient for the user to observe the hard disk indicator light 330. In particular, the front seat 140 is provided with a light guide column corresponding to the clearance hole of the hard disk indicator light 330, so as to better guide the light out for the user to observe.

[0051] Please refer to Figure 3 In particular, the upper end of the elastic plate 210 has a notch 213 , and the notch 213 abuts against the side plate 120 to limit the elastic plate 210 .

[0052] Typically, the tray body 100 is made of plastic or metal, and the bottom support plate 110, the side plate 120 and the front end seat 140 are connected by an integrated molding process or a welding process.

[0053] Please refer to Figure 5 In particular, an end surface of the hinge column 130 away from the bottom support plate 110 is provided with an anti-collision portion 133. The anti-collision portion 133 is an anti-collision notch or an anti-collision bevel groove, and the anti-collision bevel groove is inclined toward the bottom support plate 110. When the user assembles the hard disk 300 array and the insertion force is too large, the anti-collision bevel groove effectively protects the hard disk 300 gold finger from being damaged by the hard disk 300 backplane connector.

[0054] The tool-free hard drive tray of the present application is not limited to use with E3.S1T, but also includes E3.S1T 1C, E3.S1T2X1C, E3.S1T 2C, E3.S1T 4C, E3.S1T 4C+, E3.S2T, E3.S2T 1C, E3.S2T 2X1C, E3.S2T 2C, E3.S2T4C, and E3.S2T 4C+.

[0055] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).
