[0079] Please refer to Figures 1 to 4 The present invention provides an anti-vibration fan, which comprises a motor (not shown), a blade assembly 1 , a frame 2 , at least one first anti-vibration member 3 , and at least one second anti-vibration member 4 .

[0080] The motor is disposed in the center of the frame 2. The blade assembly 1 is pivotally connected to the motor and is located in the frame 2. The frame 2 has at least one engaging portion 20. In this embodiment, the frame 2 has four engaging portions 20, which are arranged symmetrically with the center of the frame 2 as a point of symmetry. Each engaging portion 20 has two opposite ends. The two opposite ends of the engaging portion 20 are respectively a first end 201 and a second end 202. Please refer to Figure 3 , Figure 6 ,and Figure 7 The engaging portion 20 has two first buckle portions 203, two second buckle portions 204, and a bottom side surface 205. The two first buckle portions 203 are located at the first end 201 and extend away from each other. The two second buckle portions 204 are located at the second end 202 and extend away from each other. The bottom side surface 205 of the engaging portion 20 faces the center of the frame 2. The material of the frame 2 can be glass fiber reinforced polybutylene terephthalate (Glass fiber reinforced Polybutylene terephthalate), and its density is 1.3 g / cm3 (g / cm 3 ) to 1.6 g / cm3 (g / cm 3 ), and based on the entire glass fiber reinforced polybutylene terephthalate, the glass fiber contained in the glass fiber reinforced polybutylene terephthalate is 30 weight percent (wt%). In the present invention, the content of glass fiber contained in the glass fiber reinforced polybutylene terephthalate applicable to the frame 2 is greater than 0wt% and less than or equal to 30wt%.

[0081] Please refer to Figures 3 to 6 . In this embodiment, the anti-vibration fan has a plurality of first anti-vibration members 3, for example, four, but the present invention is not limited thereto. Each first anti-vibration member 3 is connected to each interlocking portion 20 on the frame 2. Each first anti-vibration member 3 has two opposite ends. The opposite ends of each first anti-vibration member 3 are a third end 31 and a fourth end 32, respectively. Each first anti-vibration member 3 has two first connecting portions 33, two locking blocks 34, two first protrusions 35, two second protrusions 36, and two first fixing portions 37.

[0082] The two first connecting parts 33 are arranged at intervals from each other and are located between the third end 31 and the fourth end 32. Each of the interlocking parts 20 is arranged between the two first connecting parts 33. The two first buckle parts 203 are buckled to the two first connecting parts 33 at the third end 31. The two second buckle parts 204 are buckled to the two first connecting parts 33 at the fourth end 32. In this way, each of the first vibration-proof members 3 cannot be separated from the frame 2 along the direction from the first end 201 to the second end 202 of the interlocking part 20.

[0083] The two snap-fit ​​blocks 34 are respectively connected to the two first connecting portions 33 and extend toward each other. The two snap-fit ​​blocks 34 are snapped onto the bottom side surface 205. In this way, the first vibration-proof member 3 cannot be separated from the frame 2 in a direction away from the center of the frame 2. The two first protrusions 35 are connected to the third end 31 of the first vibration-proof member 3 and extend from the two first connecting portions 33 in a direction away from each other. The two second protrusions 36 are respectively connected to the fourth ends 32 of the two first vibration-proof members 3 and extend in a direction away from each other. The two first fixing portions 37 are located between the two first connecting portions 33 and each has a first hole 371.

[0084] The first vibration-proof member 3 is made of hard plastic, and may be polybutylene terephthalate (PBT), polycarbonate (PC), polyamide (PA), liquid crystal polymer (LCP), polyphenylene sulfide (PPS), glass fiber reinforced polybutylene terephthalate, glass fiber reinforced polycarbonate, glass fiber reinforced polyamide, glass fiber reinforced liquid crystal polymer, or glass fiber reinforced polyphenylene sulfide, but not limited thereto. In the present embodiment, the first vibration-proof member 3 is made of polycarbonate, and its density is 1.18 g / cm 3 To 1.22g / cm 3 between.

[0085] Please refer to Figure 3 , Figure 4 , Figure 6 ,and Figure 7 In this embodiment, the anti-vibration fan has a plurality of second anti-vibration members 4, for example, four, but the present invention is not limited thereto. Each second anti-vibration member 4 is mounted on each first anti-vibration member 3. The second anti-vibration member 4 has a second connecting portion 41, two second fixing portions 42, two fixing grooves 43, a first long groove 44, and a second long groove 45.

[0086] The second connecting portion 41 is connected to the first vibration-proof member 3. The two second fixing portions 42 are arranged side by side and at intervals on the second connecting portion 41. Each second fixing portion 42 has a second hole 421. In the present embodiment, two fixing grooves 43 are respectively formed in the two second fixing portions 42. The two first fixing portions 37 are respectively accommodated in the two fixing grooves 43. The first hole 371 on each first fixing portion 37 and the second hole 421 on each second fixing portion 42 are aligned with each other. In other embodiments, the two first fixing portions 37 are respectively arranged side by side with the two second fixing portions 42, so that the first hole 371 on each first fixing portion 37 and the second hole 421 on each second fixing portion 42 are aligned with each other. In this way, the vibration-proof fan can be installed on an external unit or structure by the side-by-side first hole 371 and second hole 421, and the first vibration-proof member 3 and the second vibration-proof member 4 cannot be separated from each other.

[0087] The first long groove 44 and the second long groove 45 are formed in the second connecting portion 41. One of the first protrusions 35 and one of the second protrusions 36 connected to one of the first connecting portions 33 are arranged in the first long groove 44. Another first protrusion 35 and another second protrusion 36 connected to another first connecting portion 33 are arranged in the second long groove 45. In other words, the first protrusion 35 and the second protrusion 36 facing the same direction are arranged in the first long groove 44 or the second long groove 45. In this way, the first vibration isolating member 3 and the second vibration isolating member 4 are connected to each other. In this way, the first vibration isolating member 3 and the second vibration isolating member 4 are embedded with each other and will not be separated due to vibration.

[0088] The material of the second vibration-proof member 4 is a soft plastic, which may be silicone, thermoplastic polyurethane (TPU), or thermoplastic vulcanizate (TPV), but is not limited thereto. In this embodiment, the material of the second vibration-proof member 4 is thermoplastic polyurethane, with a Shore hardness of 60A to 85D and a density of 1.10 g / cm 3 To 1.25g / cm 3 between.

[0089] When the anti-vibration fan is running, vibration occurs between the motor and the blade assembly 1, and then is transmitted to the frame 2. The interlocking portion 20 is interlocked with the first connecting portion 33 through the first snap portion 203 and the second snap portion 204, so as to transmit the vibration along the axial direction of the center of the frame 2 to the first anti-vibration member 3. At the same time, the interlocking portion 20 is interlocked with the two snap blocks 34 through the bottom side surface 205, so as to transmit the vibration perpendicular to the axial direction of the center of the frame 2 to the first anti-vibration member 3. The first anti-vibration member 3 then transmits the vibration to the second anti-vibration member 4 through the first protrusion 35 and the two second protrusions 36. Through the combination of the above multi-layer structures, the vibration further loses energy during the transmission process, thereby achieving the effect of reducing the vibration energy.

[0090] In addition, based on the design of this multi-layer structure, the first vibration-proof member 3 is made of hard plastic to make the vibration-proof fan more stable. The second vibration-proof member 4 is made of soft plastic to absorb the vibration energy transmitted by the first vibration-proof member 3 through the elasticity and viscosity of the material itself. In this way, the vibration-proof fan has both vibration-proof and stability.

[0091] The advantage of the present invention is that the anti-vibration fan achieves the effect of further reducing vibration energy through the differences in structure and medium properties between the frame 2, the first anti-vibration member 3, and the second anti-vibration member 4, thereby reducing damage to the anti-vibration fan and surrounding equipment caused by vibration.

[0092] Although the present invention is disclosed as above by the aforementioned embodiments, it is not intended to limit the present invention. Any relevant technician familiar with the art can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the patent protection scope of the present invention shall be determined by the protection scope of the claims attached to this specification.
