Description

Technical Field

[0001] This utility model relates to the field of server design technology, and specifically to a tool-free hard drive backplane that facilitates server maintenance. Background Technology

[0002] With the rapid development of computer technology, server systems, which serve as the data transmission hub, require massive storage space for data exchange. Generally, server systems have multiple hard drives. To facilitate unified maintenance and management, multiple hard drives are usually connected to a hard drive backplane, which is then connected to the server motherboard. This allows for the installation of multiple hard drives through the hard drive backplane.

[0003] A hard drive backplane is a printed circuit board that integrates hard drive interfaces, wires, and control chips, and its role in practical applications is becoming increasingly important. However, in general servers, especially 2U servers, fixing the hard drive backplane is a significant challenge due to space constraints.

[0004] Existing tool-free hard drive backplanes (a tool-free server hard drive backplane with application number 201620583695.5) use limiting protrusions and pressure plates to position and fix the hard drive backplane. The installation process requires no screwdrivers or screws, offering flexibility, high efficiency, safety, reliability, and ease of maintenance. However, this single limiting protrusion and pressure plate cannot accurately position and fix the hard drive backplane from all angles, thus affecting the quality and efficiency of server hard drive backplane maintenance and installation. Utility Model Content

[0005] In view of the above-mentioned defects or deficiencies in the existing technology, it is desirable to provide a tool-free hard drive backplane that is easy to maintain for servers. This would solve the technical problem that existing hard drive backplanes, which rely solely on a single limiting protrusion and pressure plate, cannot accurately position and fix the hard drive backplane in all directions, thus affecting the maintenance and installation quality and efficiency of server hard drive backplanes.

[0006] According to the technical solution provided in the embodiments of this application, a tool-free hard drive backplane that facilitates server maintenance includes a hard drive backplane that is installed at the rear end of each hard drive in a server chassis. The hard drive backplate has a rectangular structure, and its lower part has a rectangular array of several locking holes, so that each locking hole can be locked into the corresponding locking mechanism. Two positioning strips are installed on opposite sides of the server chassis wall for positioning and fixing the hard drive backplate on both sides. Multiple clamping mechanisms are arranged side-by-side and spaced apart inside the server chassis cover for clamping and fixing the upper part of the hard drive backplate.

[0007] Furthermore, the locking mechanism includes two locking blocks and a support plate. The support plate has a U-shaped structure, and the two locking blocks are correspondingly installed on the inner side of the support plate, and the locking blocks are engaged in the locking holes.

[0008] Furthermore, the positioning strip is provided with a U-shaped positioning groove along the vertical direction.

[0009] Furthermore, the clamping mechanism includes a clamping plate, a clamping rod, a fixed seat, and a first elastic element. The fixed seat is installed inside the box cover, while the clamping rod is movably installed inside the fixed seat, with the top of the clamping rod abutting against the first elastic element, and the clamping plate is installed at the bottom of the clamping rod.

[0010] Furthermore, a second elastic element is also sleeved on the outside of the clamping rod.

[0011] Furthermore, the bottom of the clamping plate is provided with a U-shaped slot, which engages with the clamping groove above the hard drive backplate.

[0012] Furthermore, the clamping plate, the positioning strip, and the locking block are all made of insulating material.

[0013] Furthermore, the first elastic element and the second elastic element are compression springs.

[0014] Furthermore, the support plate is made of an elastic material.

[0015] In summary, the beneficial effects of this application are as follows: 1. By setting multiple locking holes at the bottom of the hard drive backplate, and moving the two sides of the hard drive backplate down along the corresponding positioning grooves, the U-shaped support plate is opened, and the two locking blocks on the inside of the support plate are engaged with the two sides of the locking holes, thereby locking and fixing the bottom of the hard drive backplate, replacing the original limiting protrusion and pressure plate fixing method, improving the tool-free maintenance quality and efficiency of the hard drive backplate. Second, by setting multiple clamping mechanisms inside the cover plate, when the cover plate is fastened to the server chassis, the clamping plate that is engaged in the clamping groove of the hard drive back panel moves vertically and compresses the compression spring of the first elastic element, thereby clamping and fixing the top of the hard drive back panel, thereby improving the stability of tool-free maintenance installation of the server hard drive back panel. III. Explanation of the locking mechanism, positioning bar, and clamping mechanism: Through the linkage of bottom locking, lateral positioning, and upper clamping, the hard drive backplane is secured in all directions when installed inside the server chassis.

Detailed Implementation

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A tool-free hard drive backplane for easy server maintenance, its structure is as follows: Figure 1 and Figure 2 As shown, it includes a hard disk backplate 100, which has a rectangular structure and is snapped onto the rear end of each hard disk installed in the server chassis 200, replacing the original single limiting protrusion and pressing plate fixing method, thereby enabling quick plugging and unplugging of the hard disk backplate 100 for installation and maintenance.

[0021] like Figure 4 and Figure 5As shown, multiple locking mechanisms 110 are installed side-by-side and spaced apart on the bottom plate inside the server chassis 200. Each locking mechanism 110 includes two locking blocks 111 and a support plate 112. The support plate 112 has a U-shaped structure and is made of elastic material. The two locking blocks 111 are correspondingly installed on the inner side of the support plate 112. When the two sides of the hard disk backplane move down along the corresponding positioning grooves 121 of the positioning strips 120, the U-shaped support plate 112 is opened, and the two locking blocks 111 on the inner side of the support plate 112 are engaged with the two sides of the locking holes 101 provided at the bottom of the hard disk backplane, thereby locking and fixing the bottom of the hard disk backplane 100 by the locking mechanism 110.

[0022] like Figure 2 and Figure 3 As shown, two positioning strips 120 are installed on the sides of the server chassis 200, and the positioning strips 120 are provided with U-shaped positioning grooves 121 in the vertical direction so that the two sides of the hard disk backplate 100 are engaged in the positioning grooves 121, thereby positioning the two sides of the hard disk backplate 100 by the two positioning strips 120.

[0023] like Figure 2 and Figure 6 As shown, multiple clamping mechanisms 130 are arranged side by side and spaced apart inside the server chassis 200 cover 300 to clamp and fix the upper part of the hard drive backplate 100.

[0024] like Figure 3 and Figure 6 As shown, the clamping mechanism 130 includes a clamping plate 131, a clamping rod 132, a fixing seat 133, and a first elastic element 134. The fixing seat 133 is installed inside the cover 300, while the clamping rod 132 is movably installed inside the fixing seat 133, and the top of the clamping rod 132 abuts against the first elastic element 134. A second elastic element 135 is also sleeved on the outside of the clamping rod 132. The first elastic element 134 and the second elastic element 135 are metal springs. The clamping plate 131 is installed at the bottom of the clamping rod 132 so that the clamping mechanism 130 is engaged with the hard drive when the cover is fastened to the server chassis 200. The clamping plate 131 in the backplate clamping groove 102 moves vertically, compressing the spring that abuts against the first elastic element 134 and the second elastic element 135 sleeved on the outside of the clamping rod 132. The first elastic element 134 is used to replace the main clamping force, while the second elastic element 135 is used to assist in guiding and buffering the clamping rod 132. Thus, the rebound force generated after the second elastic element 135 and the first elastic element 134 are compressed pushes the clamping plate 131 connected to the clamping rod 132 to clamp and fix the hard disk backplate, thereby improving the tool-free maintenance installation stability of the server hard disk backplate 100.

[0025] like Figure 6As shown, the bottom of the clamping plate 131 is provided with a U-shaped slot so that the slot can be engaged in the clamping groove 102 above the hard disk backplate 100, thereby improving the fixation stability of the hard disk backplate 100.

[0026] like Figure 2 and Figure 3 As shown, the clamping plate 131, the positioning strip 120 and the locking block 111 are all made of insulating material to prevent the clamping plate 131, the positioning strip 120 and the locking block 111 from becoming electrified, thereby improving the installation and maintenance quality of the hard drive backplane 100.

[0027] This application installs the hard disk backplane in a 2U server, reducing maintenance time from 10 minutes to 2 minutes compared to existing technologies, while increasing the fixing strength by 20%.

[0028] The working principle of this tool-free hard drive backplane, which facilitates server maintenance, is as follows: During the installation and maintenance of the server's hard drive backplane 100, to improve the maintenance quality, multiple locking holes 101 are provided at the bottom of the hard drive backplane 100. This allows maintenance personnel to push the hard drive backplane 100 downwards along the corresponding positioning grooves 121 of the positioning strips 120 on both sides inside the server chassis 200. This causes the bottom of the hard drive backplane to open the U-shaped support plate 112, allowing two locking blocks 111 on the inner side of the support plate 112 to engage with the locking holes 101 on both sides, thus locking and fixing the bottom of the hard drive backplane. This replaces the original limiting protrusions and pressure plate fixing method, thereby improving the tool-free maintenance quality and efficiency of the hard drive backplane. Simultaneously, maintenance personnel can also... When the cover 300 above the server chassis 200 is fastened onto the server chassis 200, the clamping plates 131 on the multiple clamping mechanisms 130 installed inside the cover 300 engage with the clamping grooves 102 above the hard drive backplane. This causes the clamping plates 131 to move vertically under the push of the hard drive backplane, thereby compressing the clamping rod 132 against the first elastic member 134 and the second elastic member 135 sleeved on its outer side. The rebound force generated by the compression of the second elastic member 135 and the first elastic member 134 pushes the clamping plate 131 connected to the clamping rod 132 to press and fix it above the hard drive backplane 100, thereby improving the stability of the tool-free maintenance installation of the server hard drive backplane 100. The multiple locking mechanisms 110, positioning bars 120, and multiple clamping mechanisms 130 further improve the efficiency and quality of tool-free maintenance of the hard drive backplane 100.

[0029] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
