[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0037] Reference Figure 1 、 Figure 2 As shown, a pluggable fan module includes a handle assembly 1, a self-locking mechanism 2, a snap-fit ​​mechanism 3, a heat dissipation mechanism 4, a plug-in base assembly 5, and a light guide mechanism 6. The self-locking mechanism 2 is slidably disposed within the handle assembly 1, the snap-fit ​​mechanism 3 is fixedly sleeved on the handle assembly 1, one end of the heat dissipation mechanism 4 is fixedly connected to the snap-fit ​​mechanism 3, the plug-in base assembly 5 is fixedly connected to the heat dissipation mechanism 4, and the light guide mechanism 6 is fixedly disposed on one side of the snap-fit ​​base assembly 5. The fan module is assembled by securing the self-locking mechanism 2 within the handle assembly 1 through the handle assembly 1, then snapping the snap-fit ​​mechanism 3 onto the handle assembly 1, then securing the heat dissipation mechanism 4 and the snap-fit ​​mechanism 3 to the handle assembly 1 via bolts, and bolting the plug-in base assembly 5 to the heat dissipation mechanism 4. Finally, one end of the light guide mechanism 6 is inserted into the fan module, forming a pluggable fan module.

[0038] Reference Figure 3 As shown, the handle assembly 1 includes a handle cover 11, a square box 12, a handle 13, and a spring 14. The handle cover 11 is fixedly mounted directly above the square box 12, and a leaf spring 111 is fixedly mounted on the inner side of the handle cover 11. Two limit slots 121 are provided on both sides of the square box 12 to limit the movement of the self-locking mechanism 2. The handle 13 is slidably mounted directly below the handle cover 11, and the spring 14 is fixedly mounted between the handle cover 11 and the handle 13 to provide downward tension. When the fan module is inserted and fixed, the handle assembly 1 is in a released state, and the spring 14 and leaf spring 111 are extended. When the fan module needs to be removed, the handle cover 11 and the handle 13 are pinched together, at which point the spring 14 and leaf spring 111 are compressed, and the self-locking mechanism 2 is driven upward to release the self-locking function.

[0039] Reference Figure 4 As shown, the self-locking mechanism 2 includes two spring clip seats 21 and spring clips 22. Each spring clip seat 21 is fixedly arranged at both ends of the handle 13 for placing the spring clip 22. Each spring clip 22 is arranged in the spring clip seat 21 for self-locking the fan module. The mechanism drives the spring clip seat 21 and the spring clip 22 to work through the operation of the handle assembly 1. When the fan module needs to be removed, the handle 13 and the handle cover 11 are pinched together, and the handle moves upward. Due to the action of the upper limit slot 121 on the square box 12, the overall upward movement of the spring clip is restricted, but the tail of the spring clip 22 will continue to move upward. At this time, the head of the spring clip 22 will move downward, releasing the fixation between the fan module and the chassis shell. When it is necessary to install and lock it, it is only necessary to push the fan module into the chassis shell to be installed to automatically lock it.

[0040] Reference Figure 5 As shown, the snap-on mechanism 3 includes a snap-on cover assembly 31 and a middle frame bracket 32. The snap-on cover assembly 31 is fixedly mounted on the square box 12 for connecting and fixing the fan group module. The middle frame bracket 32 ​​is fixedly arranged between the snap-on cover assembly 31 and the heat dissipation mechanism 4 for maintaining the gap between the snap-on cover assembly 31 and the heat dissipation mechanism 4 and fixing the snap-on cover assembly 31.

[0041] Reference Figure 6As shown, the snap-on cover assembly 31 includes a honeycomb mesh 311, a connecting rod 312, and several EMI shrapnel 313. The honeycomb mesh 311 is fixed to one end of the snap-on cover assembly 31 to prevent the ingress of debris. The connecting rod 312 is fixed to one end of the several EMI shrapnel 313 to connect each of the EMI shrapnel 313. The other ends of the several EMI shrapnel 313 are fixed to the honeycomb mesh 311 to snap on and secure the fan module. The elastic force of the EMI shrapnel 313 effectively stabilizes the fan module. When the fan module is installed, it is simply pushed forward. At this time, the snap-on cover assembly 31 and the shrapnel 22 of the self-locking mechanism 2 cooperate with each other to lock and secure the fan module.

[0042] Reference Figure 7 As shown, the heat dissipation mechanism 4 includes a heat dissipation cover 41 and a heat dissipation fan 42. The heat dissipation cover 41 is fixedly connected to the square box 12 via studs. The heat dissipation cover 41 has a heat dissipation groove 411 on its surface for heat dissipation by the heat dissipation fan 42. A fan base 412 is fixedly installed inside the heat dissipation cover 41. The heat dissipation fan 42 is fixed on the fan base 412 to dissipate heat from the device. The rotation of the heat dissipation fan discharges the hot air inside the chassis shell.

[0043] Reference Figure 8 As shown, the plug-in base assembly 5 includes a base bracket 51, a socket 52, and a gold finger 53. The base bracket 51 has fixing holes on both sides for plugging the base assembly 5 into the heat dissipation mechanism 4. The socket 52 is fixedly mounted on the base bracket 51 for connecting to the gold finger 53. The gold finger 53 is fixedly mounted on the base bracket 51 to supply power to the entire fan module. Screw holes are provided on both sides of the gold finger 53 for fixing the gold finger 53 to the base bracket 51. By connecting the gold finger 53 to the socket 52 and fixing the gold finger 53 to the base bracket 51, the required power for the cooling fan 42 can be obtained by plugging the gold finger 53 into the chassis shell.

[0044] Reference Figure 9 As shown, the light guide mechanism 6 includes a light guide 61 and a light guide base 62. One end of the light guide 61 passes through the heat dissipation cover 41 and extends to the box 12. The other end of the light guide 61 is plugged into the light guide base 62 for acquiring optical signals. The light guide base 62 is fixed to one side of the base bracket 51 and is located next to the gold finger 53. By connecting the light guide to the light guide base, when the system is operating, the optical signal of the system operating status can be transmitted through the light guide to the surface of the box 12 for easy observation.
