Title:
TRANSMISSION ASSEMBLY OF FAN, FAN AND ROTATING BLADE FAN
Document Type and Number:
WIPO Patent Application WO/2018/072507
Kind Code:
A1
Abstract:
A transmission assembly of a fan, a fan and a rotating blade fan provided with the same, wherein the transmission assembly comprises: a rotating shaft (10); a rotating member (20), which cooperates with the rotating shaft (10), which is driven by the rotating shaft (10) to rotate, and which is for use in connecting a wind deflector cover (100) on an outer side of a blade of the fan such that the wind deflector cover (100) is driven by the rotating shaft (10) to rotate; a first transmission structure (30) and a second transmission structure (40), wherein one of the first transmission structure (30) and the second transmission structure (40) is disposed on the rotating shaft (10) and rotates synchronously with the rotating shaft (10), while the other of the first transmission structure (30) and the second transmission structure (40) is disposed on the rotating member and rotates synchronously with the rotating member. The first transmission structure (30) may rotate with the second transmission structure (40) such that the rotating shaft (10) spurs the wind deflector cover (100) to rotate, and when the wind deflector cover (100) becomes stuck, the first transmission structure (30) and the second transmission structure (40) may slide opposite to each other so as to disconnect a transmission engagement between the rotating shaft (10) and the rotating member (20). The transmission assembly solves the problem in the existing technology where a motor is easily damaged when a wind deflector wheel of a vane fan becomes stuck.
