Shock Mitigation Suspension Structure
A shock mitigation suspension structure of a ceiling fan, with the structure, vibrations and noise may be reduced. The shock mitigation suspension structure is used for hanging a ceiling fan on a ceiling, the ceiling fan has a pole; the shock mitigation suspension structure substantially includes a fixing frame, a bowl-shaped underprop, a fixing plate and a shock damping unit; wherein the shock damping unit is disposed in the bowl-shaped underprop and the pole goes through the shock damping unit; the fixing plate is positioned at one end of the pole going through the shock damping unit, and the fixing plate presses and resists a top surface of the shock damping unit. With the configuration, vibrations produced in rotation of the ceiling fan are transferred to the shock damping unit via the fixing plate, and the shock damping unit absorbs the vibrations. Thus noise produced from the vibrations may be reduced and life of the ceiling fan may be longer.
The invention relates to a technique for holding a ceiling fan, more particularly, to a shock mitigation suspension structure of a ceiling fan, with the structure, shock may be mitigated and noise may decrease.
A ceiling fan is usually hung on a ceiling and drived by a motor. When the ceiling fan works, air may be guided from upside of the ceiling fan to underside of the ceiling fan, which makes air within a room circulate continuously, so as to dispel cool air congregating near the ceiling and hot air congregating near the ground. When the ceiling fan cooperates with air-conditioner to cool room temperature, less energy may be consumed. Additionally, some ceiling fan having elegant shapes may be as a decoration in the room.
Usually, a ceiling fan is fixed on a suspension structure through a pole and with less pivots to a ceiling, so when the fan blades of the ceiling fan rotate at a high speed, the ceiling fan may vibrate constantly, then the tremor may be transferred to the suspension structure through the pole and produce vibration noise, finally the vibration noise may affect the living quality of a user; and constant vibration of the ceiling fan may affect the life of the ceiling fan, so how to reduce the vibration of a working ceiling fan is an issue for the manufacturers.
The inventor has been investigating the problem diligently and thoroughly, combining research and manufacture experience in the field, the inventor invents a shock mitigation suspension structure of a ceiling fan to solve the problem, the structure may obstruct effectively the way transferring the vibration to reduce vibration and noise.
BRIEF SUMMARYThe invention provides a shock mitigation suspension structure of a ceiling fan, with which, noise producing in operation of the ceiling fan may be reduced and the life of parts of the ceiling fan may be extended.
So, the invention provides a technique to achieve various objects and efficiency. According to the invention, a shock mitigation suspension structure is used for hanging a ceiling fan on a ceiling and the ceiling fan has a pole. The shock mitigation suspension structure substantially includes a fixing frame, a bowl-shaped underprop, a fixing plate and a shock damping unit. The fixing frame is fixed with the ceiling, and the bowl-shaped underprop is housed in the fixing frame, and a bottom surface of the bowl-shaped underprop has a through-hole going through the bowl-shaped underprop; the fixing plate is fixing at one end of the pole, and the pole extends into the bowl-shaped underprop; the shock damping unit is disposed between an inside edge of the bowl-shaped underprop and a bottom edge of the fixing plate, and the shock damping unit can reduce vibration.
With the technique shown in the above, the vibrations produced in the operation of the ceiling fan may be transferred from the fixing plate to the shock damping unit, and the shock damping unit obstructs and absorbs the vibrations, thus noise produced in the vibrations is effectively reduced and the life of the ceiling fan is extended. A ceiling fan with the above-mentioned characters may have additional value, which may make the ceiling fan be competitive, popular and salable.
The foregoing and other features and advantages of the present invention will be more clearly understood through the following descriptions with reference to the drawings, wherein:
These and other features and advantages of the various embodiments disclosed herein will be better understood with respect to the following description and drawings, in which like numbers refer to like parts throughout, and in which:
The invention relates to a shock mitigation suspension structure of a ceiling fan for reducing vibrations. Referring to
