Description

Fan module and the case where the fan module is applied

technical field

The present invention relates to a fan module, in particular to a fan module for improving fan assembly efficiency and a casing using the fan module.

Background technique

When computer systems (such as personal computers, server hosts, etc.) are running, waste heat will be generated correspondingly. This waste heat will increase or decrease with the operating time and operating performance of the computer system. When the waste heat gradually accumulates in the computer system, it will cause the internal temperature of the computer system to rise and affect the performance of the computer system, or even cause the computer system to crash. Therefore, a cooling device (such as a fan) is generally configured in the computer system to remove waste heat generated when the computer system is running.

The fan assembly method in the past is to place the fan on a fully-covered assembly frame first, and then assemble the assembled assembly frame and the fan together in the computer system. However, the fully-covered assembly rack needs to occupy a relatively large space, so that the internal space of the computer system cannot be effectively utilized. In addition, the full-covered assembly frame often needs to be locked by screws, which increases the difficulty of assembly. Therefore, how to improve the structure of the fan and the assembly frame so as to reduce the accommodating space required by the fan and the assembly frame and increase the convenience of assembly will be one of the problems that researchers should solve.

Contents of the invention

The second plate maintains a distance from the first plate, and has at least one first buckle structure or one guide block. The fan module includes a combined frame and a fan. The assembly frame includes an assembly base and a fan fixing base. The assembly seat extends along a first direction, and the assembly seat is detachably assembled on the first buckle structure or the guide block of the second plate. The fan fixing base is connected to the assembly base and extends toward a second direction, and the fan fixing base is detachably assembled on the first plate.

The casing disclosed in the present invention includes a fixing frame and a fan module. The fixing frame includes a first plate and a second plate. . The second plate has a first buckle structure. The fan module includes a combined frame and a fan. The assembly frame includes an assembly base and a fan fixing base. The assembly seat extends along a first direction. The first direction is parallel to the extending direction of the second board. The assembly seat is detachably assembled on the first buckle structure or the guide block of the second plate. The fan fixing base is connected to the assembly base and extends toward a second direction. The second direction is perpendicular to the first direction, and the fan fixing seat is detachably assembled on the first plate. The fan is detachably mounted on the fan fixing seat.

According to the fan module disclosed in the present invention and the casing using the fan module, the fan is assembled in a half-covered assembly frame formed by connecting the assembly base with the fan fixing base, and the required accommodation space for the half-covered assembly frame is Smaller, so it can effectively avoid wasting the internal space of the electronic device.

When the sliding body 200 is at the release position, the first abutting portion 111d and the second abutting portion 250 jointly press the elastic body 300 and reduce the protruding amount of the protruding side 111e of the second buckle structure 230 .

Then, as shown in Figure 5, since the opposite ends of the guide groove 115 are respectively located on the bottom plate 111 and the front plate 114 which are perpendicular to each other, therefore, through the guidance of the guide block 24b and the guide groove 115, and along the direction indicated by the arrow c (Parallel to the second direction) Press the combination frame 30 downwards, so that the guide block 24b is displaced relative to the guide groove 115 and displaces from the release end 115b of the guide groove 115 to the buckle end 115a, and the second engagement of the fan holder 120 The portion 123 is engaged with the first engaging portion 22 a of the first plate 22 . In this way, the relative position between the assembly frame 30 and the fixing frame 20 can be quickly located.

Next, as shown in FIG. 6 , the sliding body 200 is released, and the second abutting portion 250 of the sliding body 200 is pushed against by the elastic restoring force of the elastic body 300, so as to drive the sliding body 200 along the direction indicated by the arrow d ( parallel to the first direction) and displace from the release position to the buckle position. When the sliding body 200 is at the buckling position, the two stoppers 240 abut against the barbs 113b, and the two second buckling structures 230 protrude from the side 111e and buckle respectively on the two first buckling structures 24a, so that The assembly frame 30 can be assembled to the fixing frame 20 along the first direction and the second direction to quickly complete the fixing of the assembly frame 30 .

It should be noted that the combined frame 30 in the above embodiment is assembled to the fixed frame 20 through the sliding body 200, but it is not limited thereto. In other embodiments, the combined frame 30 can also be assembled to Fixed frame 20.

The assembly between the frame body 100 and the second plate 24 in the above embodiment of FIG. 24, but it is not limited thereto. In other embodiments, the frame body 100 and the second plate 24 can also be guided through other ways. Please refer to FIG. 7 . FIG. 7 is an exploded view of a fan module according to a second embodiment of the present invention.

In this embodiment, the second board 24 has two card slots 24c. The assembly seat 110 includes a front panel 114 and two hooks 116 .
