Shock absorbing element, shock-proof fan device with the same and computer equipment

Back to list Release date: Sep 19, 2019

in the current information industry, the use of general computers is becoming more and more extensive, and the required working efficiency is becoming more and more powerful, which increases the heat generated by internal systems of hosts such as server, thus the use of fans is also increasing.

as shown in fig.1, Taiwan patent publication No.500296 of China discloses a motor fan connecting element 9, which is used to replace a conventional screw and comprises an elastic penetrating rod 91 and a stay rod 90 arranged in the elastic penetrating rod 91, and the elastic penetrating rod 91 is contracted inward to form a recessed portion 911.the two ends of the elastic penetrating rod 91 are respectively provided with a bolt head 912, and the peripheral portion of each bolt head 912 is provided with a recessed neck 913, so as to be serially supported on a through hole 921 of a body shell wall 92, and the recessed portion of the middle section is serially connected to a motor fan the perforation 931.of the rack 93, in order to achieve the shockproof effect.

as shown in figs.2 and 3, in U.S.patent publication No.6, 351,380, the inventor disclosed a-fan connection device 80 for fixing a fan device 70 on a fan base 60, the fan device 70 is provided with a plurality of connection holes 71, and the inner wall of each connection hole 71 is convexly provided with a plurality of interference pieces 72. The fan connecting device 80 comprises at least one connecting piece 81 and a bracket 82 connected with the fan bracket 60.the connecting piece 81 has an outer elastic element 811 and an inner element 812, one end of the inner element 812 is connected with the bracket 82, and the outer

in the above two cases, when the fan is running, although the connecting element is provided with elastic material outside to absorb some vibration energy, since its inner backbone is still made of rigid material, the vibration generated by the fan running will still connect the body shell wall or the fan base, thus affecting the performance of other components in the system. Therefore, it is still necessary to develop a device that can slow down the vibration caused by fan operation.
