Description

fan mount

technical field

The invention relates to a fan fixing device, in particular to a fan fixing device with shock-absorbing effect.

Background technique

In an electronic device, one or more fans are often installed to dissipate heat from the electronic device. However, the vibration generated by the fan during operation will generate noise and affect the service life of the fan and electronic equipment.

Contents of the invention

In view of the above, it is necessary to provide a fan fixing device that can effectively absorb shock.

A fan fixing device is used to fix a fan. The fan fixing device includes a fixing frame for fixing the fan, a mounting piece and a torsion spring. An elastically deformable card is arranged on the periphery of the fixing frame. The mounting part is provided with a card hole, the fixed frame is rotatably accommodated in the mounting part, the torsion spring is fixed on the fixed frame, and the two clamping feet of the torsion spring are respectively fixed on the fixed frame and the installation part. The fixed frame rotates in the mounting part to engage the card in the card hole and elastically deform the torsion spring.

The fan fixing device of the present invention uses the torsion spring and the card to fix the fixing frame for accommodating the fan to the mounting part, thereby reducing the vibration generated by the operation of the fan.

detailed description

Please refer to FIG. 1 and FIG. 2 together. A preferred embodiment of the fan fixing device of the present invention is used to fix a fan 10 to an electronic device (not shown). The fixing device includes a fixing frame 20 for accommodating and fixing the fan 10 , a mounting part 30 fixed in the electronic equipment, a buckle 40 fixed on the fixing frame 20 and a torsion spring 50 . The fixing frame 20 is fixed on the mounting member 30 .

The fan 10 includes a connector 12 .

The fixing frame 20 includes a cylindrical body 22 . The first end 220 of the body 22 defines an opening. A bottom plate 24 is detachably mounted on the second end of the body 22 . A through hole 242 is defined near the edge of the bottom plate 24 . A U-shaped operating rod 244 protrudes from the outer side of the bottom plate 24 . The body 22 defines a through hole 221 , and a line connecting the through hole 221 and the through hole 242 is parallel to the axis of the body 22 . Two opposite buckles 222 protrude from the inner wall of the body 22 near the first end 220 . The opening of the first end 220 of the body 22 is provided with three convex strips 224, one end of the convex strips 224 is connected to each other to form a connection part approximately on the axis of the body 22, and the other end of the three convex strips 224 is connected to the body 22 the inner wall. A protrusion 246 protrudes outward from the connecting portion. A fixing post 248 protrudes outward from one of the protruding strips 224 . The fixing post 248 is adjacent to the inner wall of the body 22 . In other embodiments, the protruding strip 224 , the protruding post 246 and the fixing post 248 can be integrally formed and detachably mounted on the opening of the first end 220 .

The mounting member 30 is cylindrical and includes a bottom wall 32 and an open end 34 opposite to the bottom wall 32 . A connector 322 and a post 324 protrude from the bottom wall 32 . A locking hole 36 is defined at a periphery of the mounting member 30 . The bottom wall 32 defines a plurality of ventilation holes 320 beside the connector 322 and the post 324 to facilitate air flow.

A card 42 protrudes from the first end of the buckling member 40 .

The torsion spring 50 includes a first locking foot 52 and a second locking foot 54 .

Please refer to FIG. 3 and FIG. 4 together. During assembly, the fan 10 is installed on the bottom plate 24 of the fixed frame 20 and faces away from the operating rod 244 of the fixed frame 20 . The bottom plate 24 is installed on the second end of the fixed frame 20, and the fan 10 is accommodated in the body 22 of the fixed frame 20. At this time, the connector 12 of the fan 10 is buckled on the The buckle 222 of the body 22 . The buckle 40 passes through the through hole 242 of the bottom plate 24 , and the card 42 of the buckle 40 passes through the through hole 221 of the body 22 . The torsion spring 50 is sleeved on the protrusion 246 of the fixing frame 20 , and the first locking foot 52 of the torsion spring 50 is buckled on the fixing post 248 of the fixing frame 20 . The fixing frame 20 is installed into the mounting part 30 from the open end 34 of the mounting part 30 . And through the ventilation hole 320 , the second clip 54 of the torsion spring 50 is clipped to the clip 324 of the mounting part 30 . The card 42 elastically resists the inner wall of the installation part 30 .

Referring to FIG. 5 , the operating lever 244 of the fixing frame 20 is operated to make the fixing frame 20 rotate in the mounting part 30 . When the card 42 of the buckle 40 is buckled in the hole 36 of the mounting part 30, the connector 12 of the fan 10 is connected to the connector 322 of the mounting part 30, and the torsion spring 50 is Stretching produces deformation. The fixing frame 20 is connected to the mounting part 30 through the torsion spring 50 and the card 42, which reduces the vibration generated by the fan 10 running.

In other embodiments, the fan fixing device may not be provided with a buckle 40, but an elastic card 42 is directly protruded on the periphery of the body 22 of the fixing frame 20.
