In related technologies, when assembling rack-mount servers, it is often necessary to push each electronic device into the server rack. During this process, the bottom of the electronic device is often in close contact with the surface of the tray, which results in significant sliding friction between the electronic device and the tray. This causes considerable resistance to the electronic device as it is pushed into the server rack, making the assembly of rack-mount servers extremely inconvenient. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] This disclosure provides a support device 01 for a server rack. (In conjunction with...) Figure 1 , Figure 2 As shown, the carrying device 01 includes a tray 1 and a rolling assembly 2. The tray 1 has a receiving space, and the rolling assembly 2 includes a support structure 21 and rollers 22. At least a portion of the support structure 21 is located within the receiving space and is fixedly connected to the tray 1. The rollers 22 protrude from the surface of the tray 1 and are rotatably connected to the support structure 21.

[0033] Using the support device 01 provided in this embodiment, during the process of pushing the electronic device into the server rack, the bottom of the electronic device can abut against the roller 22, and rolling friction occurs between the two. The frictional force of rolling friction is small, thereby reducing the resistance encountered by the electronic device during the process of pushing it into the server rack, and thus improving the convenience of rack server assembly.

[0034] The phrase "roller 22 protrudes from the surface of tray 1" means that roller 22 protrudes from the upper surface of tray 1 so that roller 22 can come into contact with electronic equipment during the installation of the rack server.

[0035] The extension direction of the roller 22's shaft is perpendicular to the direction of movement of the electronic device, so that the rolling between the roller 22 and the electronic device is smoother, thereby further reducing the resistance encountered by the electronic device when it is pushed into the server rack.

[0036] Combination Figure 2 , Figure 3 As shown, in some possible implementations, the support structure 21 includes a first support portion 211, a second support portion 212, and a connecting portion 213. The first support portion 211 and the second support portion 212 are opposite to each other, and the connecting portion 213 connects the first end of the first support portion 211 and the first end of the second support portion 212. The connecting portion 213 is connected to the tray 1. The rotation shafts of the rollers 22 are connected to the first support portion 211 and the second support portion 212, respectively.

[0037] In this way, an installation space can be formed by the opposing first support portion 211 and second support portion 212 to accommodate the roller 22, allowing the roller 22 to rotate within the installation space and generate rolling friction with the electronic equipment during the installation of the cabinet server. Furthermore, during the installation of the electronic equipment, when the electronic equipment presses against the roller 22, the external force on the roller 22 can be transmitted to the second support portion 212 and the connecting portion 213, and through the connecting portion 213 connected to the first support portion 211 and the second support portion 212, the force is transmitted to the tray 1, thereby providing better support for the electronic equipment.

[0038] Optionally, the support structure 21 is formed from sheet metal of metal material.

[0039] Combination Figure 1 , Figure 2 and Figure 4 As shown, in some possible implementations, the tray 1 includes an opposing top plate 11 and a bottom plate 12. The top plate 11 has a clearance hole 111, the size of which is adapted to the connecting portion 213. The connecting portion 213 is fixedly connected to the bottom plate 12. The second end of the first support portion 211 extends away from the second support portion 212 to form a first abutting portion 2111, and the second end of the second support portion 212 extends away from the first support portion 211 to form a second abutting portion 2121. The first abutting portion 2111 and the second abutting portion 2121 abut against the top plate 11 at the edge of the clearance hole 111, respectively.

[0040] When the electronic device's pressing roller 22 applies external force to the support structure 21, the connecting part 213 can transfer the force to the bottom plate 12, while the first abutting part 2111 and the second abutting part 2121 can transfer the force to the top plate 11. In this way, force can be transferred to the tray 1 at multiple locations, reducing the concentrated load on a single location on the tray 1 and thus reducing the possibility of deformation of the tray 1. Furthermore, since the first abutting part 2111 and the second abutting part 2121 abut against the top plate 11 respectively, when the first support part 211 and the second support part 212 are subjected to large external forces, the top plate 11 can support the first support part 211 and the second support part 212, thereby reducing the possibility of structural deformation of the first support part 211 and the second support part 212 and improving the load-bearing capacity of a single rolling assembly 2.

[0041] Furthermore, during the assembly of the rolling assembly 2 and the tray 1, since the size of the clearance hole 111 is adapted to the connecting part 213, the support structure 21 can be directly inserted into the receiving space through the clearance hole 111 until the connecting part 213 abuts against the top plate 11, and the first abutting part 2111 and the second abutting part 2121 abut against the top plate 11 respectively, thereby completing the positioning of the rolling assembly 2. Thus, the assembly convenience of the rolling assembly 2 and the tray 1 can be improved.

[0042] Optionally, the connecting part 213 is fixed to the base plate 12 by means of, but not limited to, bolts.

[0043] Optionally, a first pin is provided between the first abutting part 2111 and the top plate 11. The first pin passes through the first abutting part 2111 and the top plate 11 in sequence and enters the receiving space. A second pin is provided between the second connecting part 213 and the top plate 11. The second pin passes through the second abutting part 2121 and the top plate 11 in sequence and enters the receiving space. In this way, the first abutting part 2111 and the second abutting part 2121 can be limited by the first pin and the second pin respectively, so as to reduce the possibility of displacement of the first abutting part 2111 and the second abutting part 2121, and further reduce the possibility of deformation of the support structure 21.

[0044] like Figure 2 As shown, in some possible implementations, the rolling component 2 includes a plurality of rollers 22, which are arranged at intervals.

[0045] In this way, the load can be distributed among multiple rollers 22, thereby avoiding excessive load on a single roller 22 and reducing the possibility of deformation of the support structure 21 due to excessive local stress.

[0046] like Figure 2As shown, in some possible implementations, the carrier device 01 includes a plurality of rolling components 2, which are arranged in an array of multiple rows and columns.

[0047] In this way, the array of rolling components 2 can support the electronic device at various positions, thereby reducing the possibility of the electronic device tilting up locally during movement and ensuring the stability of the electronic device's movement.

[0048] like Figure 4 As shown, in some possible implementations, the tray 1 includes a top plate 11, a bottom plate 12, and multiple side plates, with the top plate 11 opposite to the bottom plate 12, and the multiple side plates connecting the top plate 11 and the bottom plate 12. At least one of the multiple side plates has a first air vent 151, and the top plate 11 has a second air vent 112, which is connected to the first air vent 151.

[0049] In this way, an air inlet or outlet can be provided at the bottom of the electronic device, and the air inlet or outlet at the bottom of the electronic device is opposite to the second air outlet 112. Air is then supplied to or discharged from the electronic device through the air duct formed by the first air outlet 151, the second air outlet 112 and the receiving cavity, thereby increasing the air volume of the electronic device and improving its cooling performance.

[0050] Combination Figure 2 , Figure 4 As shown, in some possible implementations, one of the multiple side panels has a first air vent 151, which is an air inlet. The tray 1 also includes a baffle 13, which is located within the receiving space and at the edge of the second air vent 112 away from the first air vent 151, and opposite to the side panel where the first air vent 151 is located. The baffle 13 connects the top plate 11 and the bottom plate 12.

[0051] Thus, after the wind enters the accommodating space from the first air vent 151, the wind deflector 13 can block the wind, thereby preventing the wind from continuing to move towards the side plate where the first air vent 151 is located and the arrangement direction of the wind deflector 13, thereby changing the wind direction so that the wind flows out from the second air vent 112.

[0052] Optionally, the wind deflector 13 can be detachably connected to the top plate 11 and the bottom plate 12.

[0053] Combination Figure 2 , Figure 4 As shown, in some possible implementations, the tray 1 includes an opposing top plate 11 and a bottom plate 12, the top plate 11 having a liquid inlet 113. The carrying device 01 also includes a liquid collection structure 3, which is fixedly connected to the bottom plate 12. The liquid collection structure 3 has a liquid collection tank 31 for collecting liquid that enters the receiving space through the liquid inlet 113.

[0054] In this way, when an electronic device leaks liquid, the liquid can enter the containment space through the liquid inlet 113 on the top plate 11 and enter the liquid collection tank 31, thereby preventing the liquid leaked from a single electronic device from flowing to other electronic devices in the server rack, thus reducing the possibility of other electronic devices being damaged due to the leakage of a single electronic device.

[0055] Optionally, the liquid inlet 113 is opposite to the liquid dispensing port of the electronic device.

[0056] like Figure 5 As shown, in some possible implementations, the carrier device 01 further includes a liquid guide pipe 4. The liquid guide pipe 4 is partially located within the receiving space and is connected to the liquid collection tank 31.

[0057] Thus, when there is liquid in the collection tank 31, the liquid can be discharged from the tray 1 through the liquid guide pipe 4. For example, the liquid can be directed to the liquid collection device on the server rack, thereby preventing excessive liquid in the collection tank 31 and leakage, and further reducing the possibility of leakage from a single electronic device interfering with other electronic devices.

[0058] Optionally, a detection unit can be installed in the liquid collection tank 31 and the liquid guide pipe 4, and an alarm unit can be installed on the server rack. The detection unit is used to detect whether there is liquid in the liquid collection tank 31 or the liquid guide pipe 4. The alarm unit is electrically connected to the detection unit, so that an alarm can be issued in time when the electronic equipment leaks liquid.

[0059] like Figure 1 As shown, in some possible implementations, the carrier device 01 further includes a guide assembly 5, which includes a first guide plate 51 and a second guide plate 52 facing each other. The first guide plate 51 and the second guide plate 52 are respectively connected to the tray 1. The opposing surfaces of the first guide plate 51 and the second guide plate 52 have a plurality of guide protrusions 501, which are used to abut against electronic equipment in the server rack.

[0060] Thus, during the movement of the electronic device, multiple guide protrusions 501 can abut against the electronic device, thereby guiding the electronic device, preventing the electronic device from shifting its position, and ensuring that the electronic device is installed in the corresponding position.

[0061] Optionally, the first guide plate 51 and the second guide plate 52 are detachably connected to the tray 1.

[0062] In some possible implementations, the first guide plate 51 and the second guide plate 52 are respectively used to connect to the side wall of the server rack.

[0063] Thus, during the use of the bearing device 01, the first guide plate 51 connects the tray 1 and the side wall of the server rack respectively, and the second guide plate 52 connects the tray 1 and the side wall of the server rack respectively, thereby transmitting the force on the tray 1 to the side wall of the server rack, thereby improving the bearing capacity of the tray 1.

[0064] Combination Figure 1 , Figure 4 As shown, in some possible implementations, the tray 1 includes a top cover 1a and a base 1b. The base 1b includes a base plate 12 and a first side plate 14, a second side plate 15, a third side plate 16, and a fourth side plate 17 connected to the base plate 12, with the first side plate 14, the second side plate 15, the third side plate 16, and the fourth side plate 17 connected in sequence. The top cover 1a includes a top plate 11 and a first connecting plate 18 and a second connecting plate 19 connected to the top plate 11. The top plate 11 is connected to the second side plate 15 and the fourth side plate 17. The first connecting plate 18 and the second connecting plate 19 are opposite each other and are respectively attached to and connected to the first side plate 14 and the third side plate 16. The first end of the first connecting plate 18 and the first end of the second connecting plate 19 protrude relative to the first side plate 14 and the third side plate 16, respectively, and are used to connect to the side wall of the server rack.

[0065] In this way, the pallet 1 can form a frame structure, thereby improving the overall structural strength of the pallet 1 and enabling the load-bearing device 01 to have better load-bearing capacity. Furthermore, since the first end of the first connecting plate 18 and the first end of the second connecting plate 19 are connected to the side wall of the server rack, and the first guide plate 51 and the second guide plate 52 are also connected to the side wall of the server rack, the load-bearing device 01 can be connected to the side wall of the server rack at multiple locations, thereby distributing the load on the load-bearing device 01 and enabling it to have better load-bearing capacity.

[0066] Optionally, the fourth side plate 17 is detachably connected to the first side plate 14, the third side plate 16, the top plate 11, and the bottom plate 12, respectively. The top plate 11 also has a plurality of stop protrusions 110 for limiting the fourth side plate 17 to position the fourth side plate 17 during installation.

[0067] Based on the same concept, this disclosure also provides a server rack, such as Figure 6 As shown, the server rack includes rack 02 and the above-provided support device 01.

[0068] Combination Figure 6 , Figure 7As shown, the rack 02 includes two first square hole strips 021 and multiple second square hole strips 022. The first square hole strips 021 and the second square hole strips 022 are arranged vertically, and multiple square holes are provided on the first square hole strips 021 and the second square hole strips 022. The two first square hole strips 021 are respectively located near the front door of the server on the rack 02, and the multiple second square hole strips 022 are respectively located on the left and right side walls of the rack 02. The first end of the first connecting plate 18 and the first end of the second connecting plate 19 are respectively fixedly connected to the two first square hole strips 021, and the first guide plate 51 and the second guide plate 52 are respectively fixedly connected to the second square hole strips 022.

[0069] In addition, rack 02 also includes two third-party hole strips, which are located near the rear of the server. The two ends of the fourth side plate 17 are fixedly connected to the two third-party hole strips respectively.

[0070] During the installation of the server rack, the support device 01 without the fourth side plate 17, guide assembly 5, and liquid guide tube 4 is first mounted on the rack. Then, screws are used to fix the first end of the first connecting plate 18 and the first end of the second connecting plate 19 to the first square hole strip 021 on the front side of the rack 02. After that, the fourth side plate 17 is assembled onto the support device 01, and screws are used to fix the fourth side plate 17 to the third square hole strip on the rear side of the rack 02. Then, the first guide plate 51 and the second guide plate 52 are fixed onto the tray 1 with screws, and the first guide plate 51 and the second guide plate 52 are fixed onto the second square hole strip 022 on the side wall of the rack 02 with Cam screws. Finally, the liquid guide tube 4 is assembled onto the support device 01.

[0071] Combination Figure 8 , Figure 9 As shown, using the rack provided in this embodiment, during the process of pushing the electronic device 03 into the server rack, the bottom of the electronic device 03 can abut against the roller 22, and rolling friction occurs between them. The frictional force of rolling friction is small, thereby reducing the resistance encountered by the electronic device 03 during the process of pushing it into the server rack, and thus improving the convenience of rack server assembly. Furthermore, during this process, the guide protrusions 501 on the first guide plate 51 and the second guide plate 52 can guide the electronic device 03, thereby ensuring the stability of the movement of the electronic device 03.
