Detailed Embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1

[0027] As Figure 1As shown in the figure, Embodiment 1 of the present disclosure discloses a vibration damping assembly for a vibration damping alloy fan. The vibration damping assembly 1 includes a first connecting frame 11, a second connecting frame 12, and a plurality of vibration damping bodies 13. The first connecting frame 11, the second connecting frame 12, and the vibration damping bodies 13 are all made of vibration damping alloy materials. The first connecting frame 11 is suitable for absorbing radial vibration forces, and the vibration damping bodies 13 are suitable for absorbing vertical vibration forces. The second connecting frame 12 is an optional component, which is suitable for making a conversion connection when the size of the fan protection cover assembly 3 does not match that of the first connecting frame 11.

[0028] Based on practical applications, such as Figure 2 As shown in the figure, the outer shape of the first connecting frame 11 is a square body. The outer side of the square body is a first outer frame 111, and a first inner ring 112 is provided in the center. The space between the first outer frame 111 and the first inner ring 112 is hollowed out, and the two are connected by a plurality of first reinforcing ribs 113. Specifically, there are 8 first reinforcing ribs 113, which are evenly distributed on the outer side of the first inner ring 112. The hollow design provides a ventilation function on the one hand, and on the other hand, leaves a space for the first connecting frame 11 to deform, so as to consume and absorb part of the radial vibration force. Four of the spaced first reinforcing ribs 113 of the first connecting frame 11 are provided with first mounting holes 114 for connecting with the second connecting frame 12. The first connecting piece used here can be a countersunk head screw. Four fifth mounting holes 115 are pre-opened on the first outer frame 111 of the first connecting frame 11 for connecting with the chassis of external equipment. The number of the first mounting holes 114 and the fifth mounting holes 115 is not limited to the number disclosed in Embodiment 1 and can be flexibly set according to needs.

[0029] Based on practical applications, such as Figure 2 As shown in the figure, the second connecting frame 12 is a square body, which is the same size as the protection cover of the fan 2. The second connecting frame 12 includes a second outer frame 121 and a second inner ring 122. The space between the second outer frame 121 and the second inner ring 122 is hollowed out, and the two are connected by a plurality of second reinforcing ribs 123. Specifically, there are 12 second reinforcing ribs 123, which are evenly distributed on the outer side of the second inner ring 122. The hollow design provides a ventilation function on the one hand, and on the other hand, leaves a space for the second connecting frame 12 to deform, so as to consume and absorb part of the radial vibration force. Four of the spaced second reinforcing ribs 123 of the second connecting frame 12 are provided with second mounting holes 124 for connecting with the first connecting frame 11. In addition, four third mounting holes 125 are pre-opened on the second outer frame 121 of the second connecting frame 12, and a second connecting piece is used to connect with the vibration damping body 13. The second connecting piece uses a long bolt. The number of the second mounting holes 124 and the third mounting holes 125 is not limited to the number disclosed in Embodiment 1 and can be flexibly set according to needs.

[0030] Based on practical applications, such as Figure 2As shown, the vibration damper 13 is a cylinder, and the circumferential side wall of the cylinder is provided with two rotating thread grooves 131. A through fourth mounting hole 132 is provided in the middle of the cylinder, and the two ends of the fourth mounting hole 132 are respectively adapted to the third mounting hole 125 of the second connecting frame 12 and the sixth mounting hole 31 of the protective cover assembly 3 of the fan 2. Preferably, four vibration dampers 13 are provided, and are evenly installed at the four corners of the protective cover assembly 3 of the fan 2.

[0031] Based on the above, Figure 2 As shown, the vibration reduction assembly 1 also includes a plurality of sleeves 14, which are made of a vibration-damping alloy and are used to be installed between the front shell and the rear shell of the protective cover assembly 3 of the fan 2, so as to enhance the installation warning force and the vibration bearing capacity of the protective cover of the fan 2. Specifically, four sleeves 14 are preferably provided. A seventh through mounting hole 141 is provided in the middle of each sleeve 14, which is used to adapt to the sixth mounting hole 31 of the protective cover assembly 3 of the fan.

[0032] The operating principle of this embodiment is as follows: during installation, first place the four sleeves 14 between the front shell and the rear shell of the protective cover assembly 3 of the fan, corresponding to the position of the sixth mounting hole 31; then place the four vibration dampers 13 above the rear shell of the protective cover assembly 3 of the fan 2, corresponding to the position of the sixth mounting hole 31; then place the second connecting frame 12 above the vibration damper 13, so that the third mounting hole 125 of the second connecting frame 12 corresponds to the fourth mounting hole 132 of the vibration damper 13; use four long bolts for fastening, each long bolt passes through the third mounting hole 125, the fourth mounting hole 132, the first sixth mounting hole 31, the seventh mounting hole 141, and the second sixth mounting hole 31 in sequence, connects the second connecting frame 12, the vibration damper 13, the disassembled protective cover assembly 3, and the sleeve 14, and the ends are fastened by nuts. Finally, install the first connecting frame 11 and place it above the second connecting frame 12 so that the first mounting hole 114 of the first connecting frame 11 corresponds to the second mounting hole 124 of the second connecting frame 12, and fasten the first connecting frame 11 and the second connecting frame 12 with four countersunk screws.

[0033] The vibration absorption principle of the vibration damping assembly 1 is as follows: relying on the vibration damping property of the vibration damping alloy material itself, the first connecting frame 11, the second connecting frame 12 and the vibration damping body 13 can absorb part of the vibration. The hollow design of the first connecting frame 11 and the second connecting frame 12 can provide slight deformation in the radial direction, consume energy and absorb vibration in the radial direction. The two spiral grooves of the vibration damping body 13 have a spring-like shape as a whole. When subjected to force, vertical compression and stretching will occur, consuming energy and effectively absorbing vertical vibration.

[0034] Example 2

[0035] A fan 2, the fan 2 includes a protective cover assembly 3, an impeller assembly 4 and a motor drive assembly 5, and further includes a vibration damping assembly 1 made of the above-mentioned vibration damping alloy material. During installation, the fan 2 with the vibration damping assembly 1 is connected to the chassis of an external device through the fifth mounting hole 115 of the first connecting frame 11. When the vibration of the fan is transmitted to the chassis, the vibration damping assembly 1 first absorbs vibration radially and vertically through the first connecting frame 11 and the vibration damping body 13 made of vibration damping alloy, and then the second connecting frame 12 made of vibration damping alloy is used to assist in reducing vibration.

[0036] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
