Moreover, the shock prevention structure includes integrating at least a shock prevention element and a gasket. As the shock prevention element is made of a flexible material being shock-absorbent and damping, the vibration amplitude during motor rotation won't be transmitted to the bottom plate and the electronic system due to the damping function of the shock prevention element, and the resonant effect and noise out of vibration occurring in an electronic system is avoided.

Abstract: The present invention relates to a brushless DC motor structure providing at least a dust-filtering element between a holder of a rotor and a bearing. The dust-filtering element is made of a porous and absorbent material and nearly or slightly contacts with the holder and a spindle. As such, when particles and dust in air enter the motor structure to be completely filtered, blocked, and absorbed by the porous dust-filtering element, no particles and dust will get into the spindle seat to be mixed with lubricant in formation of oil sludge, thereby ruling out the blocking and locking issue of the spindle arising from the oil sludge and prolonging the operation life span of the motor.

Abstract: This invention relates to an oil retaining structure of a spindle, wherein the outer peripheral surface of the spindle is provided with a first oil groove extending spirally along a clockwise direction and a second oil groove extending spirally along a counterclockwise direction. The first oil groove and the second oil groove across each other so as to form a plurality of collecting points. In operation, the oil film formed on the outer peripheral surface of the spindle will collect in the two oil grooves slowly, and the lubricating oil in the two oil grooves will bump into each other at the collecting points and then diffuse. As a result, an interior cycle is formed, which not only prevents the leaking of the lubricating oil but also makes the lubricating oil distribute evenly on the surface of the spindle.

Abstract: An improved cooling module holder has a main body with two sides, a cooling fan and a heat sink disposed on the both sides respectively in formation of a cooling module. The ventilation hole corresponding to the cooling fan is disposed on the main body. At least one still leaf extends inwardly from the inner rim of the ventilation hole. When the cooling fan drives air flow to pass through those leaves, the still leave enables to lower the noise resulting from the pressure resonance and eliminating the unnecessary pressure loss caused by turbulence. Another wind pressure is formed along the tangent direction of the still leaf capable of avoiding the loss from the wind pressure. Meanwhile, the cooling performance of the cooling fan is enhanced by the wind pressure, achieving faster and more efficient cooling effect and improving the overheated issue at the lower half of the heat sink.

By means of the magnetic attraction and mutual traction, the driven element inside the cooled part is driven to synchronously rotate along with the hub, not only dissipating the heat of the cooled part, but also achieving dual effects inclusive of heat dissipation and power driving by means of the power supplied by the traction through the magnet or the permeable component.

Abstract: The invention relates to a heat sink structure, which includes a central heat conducting body having a plurality of cooling fins extending from the periphery of the central heat conducting body, a through hole therein penetrating both sides thereof, and a cover plate and a bottom plate enclosing both openings of the through hole so as to form a chamber filled with a cooling liquid. The bottom plate is swappable with the material having a higher thermo-conductivity coefficient than that of the chamber so as to have faster and better heat absorption and heat transfer effect. If combined with the auxiliary cooling fins, the heat exchange area of the cooling liquid not only is increased, but also the mixing turbulent flow effect of the cooling liquid is enhanced so that the heat absorbed is more swiftly and uniformly diffused to provide the fastest and the most efficient cooling effect.
