Description

    BACKGROUND OF THE INVENTION
  • (a) Field of the Invention
  • The present invention relates to a fan vibration absorber device, and more particularly to a fan vibration absorber device that effectively reduces transmission of vibrational torque of fans, and lowers noise output therefrom.
  • (b) Description of the Prior Art
  • Air convection produced by high speed rotation of heat dissipating fans conventionally used in computer power supply devices or host computers achieves the objective of dissipating heat from the electronic components.
  • However, when the fans are rotating, torque produced by the fan blades is transmitted to a support body of the host computer, circuit boards or the case of the computer power supply device. Moreover, the high vibration and noise produced after the fan blades have been rotating for a long period of time also cause loosening of connecting bolts on the support body or case.
  • Thus, it is a feature of the present invention to provide a fan vibration absorber device that overcomes the aforementioned shortcomings of prior art.
    • SUMMARY OF THE INVENTION
  • A primary objective of the present invention is to provide a fan vibration absorber device that is able to reduce vibrational moment of fans and lower noise output in a host computer case or a power supply device.
  • To enable a further understanding of said objectives and the technological methods of the invention herein, brief description of the drawings is provided below followed by detailed description of the preferred embodiments.

  • flexible pins 40, each of which have a neck portion 42 of relatively small diameter and an insert end 41, and the flexible pins 40 respectively insert into the connecting holes 32 of the flexible pads 30 and the through holes 12, 22 of the left and right side fans 10, 10′, 20, 20′ respectively.
  • Referring to FIGS. 1 and 2, the flexible pads 30 and the pins 40 are fabricated from rubber material, and a protruding piece 33 extends from one side of each of the flexible pads 30.
  • A front end of the neck portion 42 of each of the pins 40 assumes a tapered form 44, and a rear wall 45 of relatively large surface area is formed at a rear end of the neck portion 42 (see FIG. 3).
  • The flexible pads 30 have concave surfaces 35 that cover and join to outer surfaces 141, 241 of the connecting frames 14, 24 respectively.
  • Referring to FIGS. 1 and 2, wherein the flexible pads 30 have two or more of the hollow portions 31, 31′. A connecting member 301 connects the adjacent hollow portions 31, 31′, and a through hole 302 is defined in each of the connecting members 301. Two adjacent sides of the flexible pads 30 respectively adjoin the pair of left side fans 10, 10′ and the pair of right side fans 20, 20′;
  • The neck portion 42 of each of the pins 40 penetrates the through holes 22, 12 of the right side fans 20, 20′ and the left side fans 10, 10′ respectively and the respective connecting holes 32 of the flexible pads 30, thereby positionally fixing the structural configuration of an embodiment of the present invention.
  • Referring to FIGS. 4 and 5, wherein an inner surface of each of the protruding pieces 33 respectively covers and joins to surfaces of the connecting frames 14, 24 of the left side fans 10, 10′ and the right side fans 20, 20′.
  • Referring to FIGS. 4 and 5, wherein an assemblage 100 of the left side fans 10, 10′ and the right side fans 20, 20′, the flexible pads 30 and the pins 40 is securely installed within a case 50 that serves as an outer case for a power supply device.
  • Referring to FIGS. 1 and 2, which show an elevational view and an exploded elevational view s of an assembly of four fans respectively, including left fans 10, 10′ and right fans 20, 20′. The fans 10, 10′ and 20, 20′ are provided with two quadrilateral connecting frames 14, 24 respectively. An embodiment of the present invention comprises at least more than one rubber pad 30, with a preferred embodiment having a configuration including three pads 30, each of which can be designed with a connecting member 301 according to needs. The connecting member 301 and the pad 30 are formed as an integrated body that provides a resiliently deformable characteristic to the configuration when subjected to a force, and reciprocal connecting of the two sets of adjacent left fans 10, 10′ and the two sets of adjacent right fans 20, 20′, along with resilient deformability of the connecting members 301, enable mutual displacement. Moreover, in order to facilitate assembling an assemblage 100 at different relative positions interior of a case 50, hollow portions 31, 31′ are defined in the pads 30 to correspond to air inlets or air outlets of the fans 10, 20, 10′, 20′ respectively.
  • Referring to FIG. 3, insert ends 41 and tapered forms 44 of pins 40 insert and penetrate through holes 12, 22 of the left side fans 10, 10′ and the right side fans 20, 20′ respectively. A neck portion 42 of relatively small external diameter of each of the pins 40 tightly fits into the through holes 12, 22.

  • Concave surfaces 35 of the pads 30 cover and join to surfaces 141, 241 of the connecting frames 14, 24 respectively, and the connecting frames 14, 24 of the left and right side fans 10, 10′, 20, 20′ covered and positioned on the flexible and vibration-absorbing pads 30 enable the entire assemblage 100 to be securely installed within the case 50. Moreover, all contact surfaces between the assemblage 100 and the case 50 have one of the pads 30 disposed therebetween. Hence, the greater part of the torque produced by the high speed rotation of the left and right fans 10, 10′, 20, 20′ is equally absorbed by the pads 30, thereby achieving vibration-absorbing effectiveness and substantially reducing the vibrational torque on the assemblage 100 assembled in the case 50, and, thus, preventing loosening of screw component members interior of the case 50 (such as bolts), and lowering noise produced by vibration.
  • Referring to FIGS. 4 and 5, which depict the assemblage 100 being installed within the case 50 and the assemblage 100 securely installed within the case 50 respectively. A circuit board 55 with an electronic component member 56 (such as a transformer) fixedly soldered thereon is installed within the case 50. Because of the pads 30 disposed between all contact surfaces between inner surfaces of the case 50 and the assemblage 100, thus, the pads 50 absorb vibrational force of the torque produced when the fans 10, 10′, 20, 20′ are rotating, thereby substantially reducing vibrational force transmitted to the case 50.
  • At least more than one of the pads 30 is connected to the plurality of fans 10, 10′, 20, 20′, the number of pads 30 being determined by operating requirements.
  • In conclusion, objectives achieved by the characteristics of the present invention, uniqueness and advancement of the present invention clearly comply with essential elements as required for a new patent application. Accordingly, a new patent application is proposed herein.
