Description

Technical Field

[0001] The utility model relates to the technical field of servers, in particular to a fan module with a self-locking characteristic and a cabinet for installing the fan module. Background Art

[0002] In a server, multiple fan modules are often installed inside the chassis to dissipate heat for the server system. As a heat dissipation component in a server, the fan module plays an important role. In the prior art, the fan module in a server is usually designed in the following three ways:

[0003] 1. The fan bracket is riveted with captive screws, which are fixed to the chassis by hand. When the fan module fails, the captive screws need to be manually unscrewed. This method realizes tool-free disassembly and assembly, but the efficiency is relatively low.

[0004] 2. The fan bracket is riveted with an elastic hook, which is used to hook and fix the fan module to the chassis by elastic deformation. During reliability testing, the elastic hook is prone to failure, causing the fan module to loosen. This method has low reliability.

[0005] 3. The fan bracket is disassembled into multiple parts, and the multiple parts are matched to form a quick-disassembly design. This method has a complex design structure and high cost.

[0006] In view of this, the utility model provides a fan module with a self-locking feature to solve the defects and problems existing in the prior art. Utility Model Content

[0030] The following describes the specific implementation of the utility model in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the utility model. Although the utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, rather than limiting the scope of the utility model.

[0031] like Figures 1 to 4 As shown, a fan module with self-locking characteristics, the fan module 3 is provided with a rotating handle 3-1, a fan bracket 3-2, a fan 3-3, a rotating rivet 3-4, a screw 3-5 and a fan plug 3-3-1. The fan module 3 is plugged into the mounting frame 2 on the chassis 1, as shown in FIG. Figure 3 , Figure 4As shown, there is a gap between the left and right sides of the fan bracket 3-2 and the mounting frame 2, and the rotating handle 3-1 is U-shaped, and its two ends are connected to the left and right sides of the fan bracket 3-2 by rotating rivets 3-4 to form a lever structure. In order to make the lever structure formed by the rotating handle 3-1 and the rotating rivet 3-4 more labor-saving, the rotating rivet 3-4 is located closer to the end of the rotating handle 3-1. Figure 2 As shown, the inner side of the mounting frame 2 is provided with two cylindrical positioning columns 2-1 on the left and right. When the fan module 3 is plugged into the mounting frame 2 by rotating the handle 3-1, the U-shaped end faces at both ends of the rotating handle 3-1 abut against and slide against the outer contour surface of the positioning column 2-1. By adjusting the angle of the rotating handle 3-1, the position of the fan module 3 in the mounting frame 2 can be adjusted. Figure 3 As shown, a limiting fold 3-1-1 is provided at the upper end of the rotating handle 3-1. When the limiting fold 3-1-1 contacts the fan bracket 3-2, the force direction at the contact point between the rotating handle 3-1 and the positioning column 2-1 is parallel to the plug-in direction of the fan module 3 and the mounting bracket 2. At this time, after the fan module 3 and the mounting bracket 2 are plugged into place, the angle between the limiting fold 3-1-1 and the fan bracket 3-2 is adjusted by rotating the handle 3-1 to realize the overall insertion and removal of the fan module 3 in the mounting bracket 2.

[0032] like Figure 1 As shown, the mounting frame 2 is connected to a fan back plate 4, and the fan back plate 4 is provided with a fan socket 4-1. Figure 3 , Figure 5 As shown, the fan 3-3 is fixedly connected to the fan bracket 3-2 by screws 3-5, and the fan 3-3 has a fan plug 3-3-1. When the limit fold 3-1-1 contacts the fan bracket 3-2, the fan plug 3-3-1 is plugged into the fan socket 4-1 on the fan back plate 4. Figure 6 As shown, at this time, the rotary handle 3 - 1 , the rotary rivet 3 - 4 and the positioning column 2 - 1 constitute an equivalent four-bar mechanism and the equivalent four-bar mechanism is in a dead point position, and the fan module 3 is self-locked on the mounting frame 2 .

[0033] It should be explained in detail that the self-locking property of the fan module 3 is derived from the equivalent four-bar mechanism abcd formed between the rotating handle 3-1 of the fan module 3, the rotating rivet 3-4 and the positioning column 2-1. Figure 7As shown, when the fan module 3 is installed in place, the rocker bc and the connecting rod cd are in line. With the rocker ad as the active part, that is, when the fan module 3 is pushed in the direction of the separation chassis 1 by external force, the force direction of the abutment between the rotating handle 3-1 and the positioning column 2-1 is parallel to the plugging direction of the fan module 3 and the mounting frame 2, and the equivalent four-bar mechanism formed by the rotating handle 3-1, the rotating rivet 3-4 and the positioning column 2-1 is in the dead point position. The equivalent four-bar mechanism is self-locking, and the fan module 3 can be reliably fixed without additional screws, thereby achieving the effect of fixing the fan module 3 without screws.

[0034] It is worth noting that this design method of the fan module 3 with self-locking characteristics is not only applicable to the fan module 3 with self-locking characteristics, but also applicable to other modules with rapid disassembly and assembly requirements, and has a wide range of applications.

[0035] The working principle of the fan module with self-locking characteristics of the utility model is as follows:

[0036] Install and fix the fan module: first adjust the rotating handle 3-1 to rotate to the appropriate angle with the fan bracket 3-2, then push the fan module 3 into the mounting frame 2 in the chassis 1, and when the rotating handle 3-1 is pushed to rotate toward the mounting frame 2, the rotating handle 3-1 moves along the outer contour edge of the positioning column 2-1, and the rotating handle 3-1 will move toward the chassis 1, and then rotate the limit folding edge 3-1-1 on the rotating handle 3-1 to the position flush with the fan bracket 3-2, and the fan plug 3-3-1 of the fan 3-3 is plugged into the fan socket 4-1 on the fan backplane 4. The equivalent four-bar mechanism formed by the rotating handle 3-1, the rotating rivet 3-4, and the positioning column 2-1 is in the dead point position, and the mechanism is self-locking, and no additional screws are needed to fix the fan module.

[0037] Pull out the fan module: Figure 8 As shown, the rotating handle 3-1 is unscrewed. During the unscrewing process, the rotating handle 3-1 moves along the outer contour edge of the positioning column 2-1. At this time, the rotating handle 3-1 will move in the direction of leaving the chassis 1. The lever structure formed by the rotating handle 3-1 and the rotating rivet 3-4 separates the fan module 3 from the mounting frame 2, and the fan module 3 is pulled out.

[0038] like Figure 1 As shown, a cabinet is composed of a chassis 1, a mounting frame 2, a fan module 3 and a fan back plate 4. The chassis 1 is provided with at least two groups of the above-mentioned fan modules 3, and the mounting frame 2 and the fan back plate 4 are matched with the fan modules 3.

[0039] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
