Embodiment

Hereinafter with reference to relevant drawings, the fan shock-damping structure according to the utility model preferred embodiment is described, to be convenient to understand for making, the same components among the following embodiment illustrates with identical symbology.

With reference to Fig. 1 and Fig. 2, it is the decomposition and the combination schematic representation of the utility model fan shock-damping structure.Among the figure, the fan shock-damping structure comprises blower module 1 and Buffer Unit 2.

Blower module 1 has fan unit 11, housing 12 and at least two limited parts 13, and fan unit 11 is arranged in the housing 12, and each limited part 13 is arranged at housing 12 outsides.Limited part 13 in the form of a ring and have breach 131, spacing hole 132 and at least one position limit arm 133.Breach 131 is positioned at a side of position limit arm 133, and spacing hole 132 runs through position limit arm 133 and defined by limited part 13 inwalls, and wherein, breach 131 communicates with spacing hole 132.In the present embodiment, represent with three limited parts 13, but not as limit.And limited part 13 can be arranged at blower module 1 and parallel place or place, diagonal angle.

Buffer Unit 2 can be made cylinder body shape by elastic material, and Buffer Unit 2 its bodies are provided with positioning hole 21, and wherein Buffer Unit 2 has first positioning part 22, second positioning part 23 and locating column 24.Locating column 24 connects first positioning part 22 and second positioning part 23.Wherein, first positioning part 22 and second positioning part 23 are cylindrical body.When locating column 24 snapped in spacing hole 132 by breach 131, positioning hole 21 was from bottom to top through the body of Buffer Unit 2.The vibrations that Buffer Unit 2 main effects are produced when being to absorb blower module 1 running.

When extruding Buffer Unit 2 makes locating column 24 produce deformation and when being easy to by breach 131, according to stopping extruding and buffer release assembly 2, make locating column 24 reinstatements, with clip in the spacing hole 132 that limited part 13 inwalls are defined, again according to its pairing first, second

position limit arm

1331,1332 upper limbs of first positioning part, 22 clips, and, Buffer Unit 2 is fixed on the limited part 13 according to its pairing first, second

position limit arm

1331,1332 lower edges of second positioning part, 23 clips.

In the present embodiment, position limit arm 133 is represented by first position limit arm 1331 and second position limit arm 1332, also can represent (as shown in Figure 3) with single position limit arm 133.

When blower module 1 high speed rotating, fan unit 11 imbalances (Unbalance) are the main causes that causes vibrations.Fan unit 11 imbalances are because the leaf quality skewness causes, and when fan unit 11 rotation, the axle center that the leaf quality skewness can cause fan unit 11 is (Radial) formation acceleration and produce centrifugal force radially.This centrifugal force makes the axle center of fan unit 11 move along force direction (being the direction of radial centrifugal force) with the blade rotation, this moves and is the main cause that produces vibrations, in brief, the every fortune in the axle center of fan unit 11 turns around, and produces the physical phenomenon of vibrations because of bearing unbalanced force.The perhaps axis deviation rotating center of fan unit 11 thereby form uneven particle, the axle center particle imbalance of this fan unit 11 also are that another that produce vibrations influences key element.

With reference to Fig. 4 and Fig. 1, wherein Fig. 4 is used in schematic representation on the substrate for the utility model fan shock-damping structure.Among the figure, the fan shock-damping structure also comprises positioning component 3.Positioning component 3 is can be by the rigidity material made and be installed on the substrate 4 (as computer casing, central processing unit (CPU) shell or power supply unit shell), and for example positioning component 3 directly penetrates to substrate 4 with plastics, perhaps sets to substrate 4 with rivet.

Wherein, positioning component 3 upper limbs have jut 31, and positioning hole 21 is sheathed on jut 31.Wherein the diameter 311 of jut can be less than the aperture (this positioning hole 21 is defined by Buffer Unit 2 inwalls) of positioning hole 211, to reduce the Buffer Unit 2 inwalls jut 31 of directly conflicting, is passed to jut 31 and reduce shaking force.

Therefore, above-mentioned positioning hole 21 is sheathed on jut 31, utilize Buffer Unit 2 absorb directions X that blower modules 1 running produced and Y to displacement, also promptly reduce blower module 1 forward and backward, left and right vibrations, so the minimizing shaking force is transmitted to other assembly (for example computer casing, Winchester disk drive, circuit board, media play CD-ROM drive) on the electronic equipment, and can prevent causing unstable aspect to take place and noise-decreasing in stop signal transmission or the signal forming process.

With reference to Fig. 5 and Fig. 1, wherein Fig. 5 is used in substrate and upper plate schematic representation for the Buffer Unit of the utility model fan shock-damping structure.Among the figure, the fan shock-damping structure also comprises upper plate 5.Blower module 1 is arranged between substrate 4 and the upper plate 5, defines spacing 6 between substrate 4 and the upper plate 5.And Buffer Unit 2 has height 25, therefore height 25 is greater than above-mentioned spacing 6,, Buffer Unit 2 is arranged between substrate 4 and the upper plate 5, in order to contact upper plate 5 and compress substrate 4, to reduce the displacement (vibrations) of blower module 1 along the Z direction, in brief, promptly reduce blower module 1 vertical tremor.

In sum, the shaking force that the fan unit rotation produces is cushioned assembly and absorbs, thereby significantly lower shaking force and be sent to other assembly on the electronic equipment, and then the minimizing blower module shakes and electronic equipment shakes the noise of (shake identical with blower module frequently) the two formation altogether, can prevent electronic equipment damage, instability and produce discordant sound.

The above only is an illustrative, but not is restricted person.Anyly do not break away from spirit of the present utility model and category, and, all should be contained in the scope of patent protection its equivalent modifications of carrying out or change.
