The swinging driver 24 drives the driving gear 23 to rotate around the periphery of the central gear 22, and the driving gear 23 is arranged on the fan head 1 and moves synchronously, so that the fan head 1 swings under the driving of the driving gear 23. The swing head driver 24 may be a motor or an electric motor, such as a stepping motor. The outer peripheries of the sun gear 22 and the drive gear 23 are provided with respective tooth portions, which may be only partial regions, such as the full region of the outer periphery, 1/3 region of the outer periphery, 1/2 region of the outer periphery, 1/4 region of the outer periphery, 1/6 region of the outer periphery, 1/5 region of the outer periphery, and so forth. In the preferred embodiment, the drive shaft 21 extends in a transverse direction.

The fan head 1 includes a mounting rack 11 for mounting the blade driver 4, that is, the mounting rack 11 is used for mounting the blade driver 4 for driving the blades to rotate. In a preferred embodiment, a swing head driver 24 and a driving gear 23 are further mounted on the mounting frame 11, so that the swing head mechanism does not occupy additional space and does not need to additionally design other mounting frames. The fan head 1 also comprises a rear housing 12, and in other embodiments the yaw drive 24 and the drive gear 23 may also be mounted on the rear housing 12.

The number of the rotating shafts 21 may be one, two, or the like. In the preferred embodiment, the first rotating shaft 211 and the second rotating shaft 212 are formed to extend from both sides of the mounting frame 11, i.e. two rotating shafts, or one rotating shaft may be fixed to the mounting frame 11. The central gear 22 is sleeved on the first rotating shaft 211, and the driving gear 23 is arranged on one side of the mounting rack 11 extending from the first rotating shaft 211. Specifically, the mounting block 11 includes a main plate 111 and side plates 112 disposed at both sides of the main plate 111, the vane driver 4 is mounted at a back surface of the main plate 111, a driving shaft of the vane driver 4 extends from the main plate 111 and is connected to the vanes, a first rotating shaft 211 and a second rotating shaft 212 are respectively formed by extending in opposite directions from the two side plates 112 of the mounting block 11, and the yaw drive 24 and the drive gear 23 are disposed on the side plates 112. The swing head driver 24 is disposed inside the side plate 112, the driving shaft of the swing head driver 24 extends from the side plate 112, and the driving gear 23 is disposed outside the side plate 112 and connected to the driving shaft of the swing head driver 24.

A torsion spring 25 is fitted around the first rotating shaft 211. The torsion spring 25 is located between the central gear 22 and the side plate 112 of the mounting bracket 11, one end of the torsion spring 25 is connected to the central gear 22, and the other end of the torsion spring 35 is connected to the side plate 112 of the mounting bracket 11.

A first engaging groove (not shown) is formed in the first rotating shaft 211, and a first engaging ring 26 is engaged with the first engaging groove for axially fixing the sun gear 22 relative to the first rotating shaft 211 to avoid slippage.

The end of the second rotating shaft 212 is sleeved with a bushing 27, the second rotating shaft 212 rotates relative to the bushing 27, and the bushing 27 is fixed by the fixing frame 3. The fixing frame 3 is roughly in the shape of a horn frame, and two angles of the horn are respectively used for fixing the shaft sleeve 27 and the central gear 22. A second locking groove (not shown) is formed on the second rotating shaft 212, and a second locking ring 28 is clamped on the second locking groove to further avoid the sliding phenomenon.

When the swing head driver is in a working state, the driving gear is driven to rotate by the swing head driver. Because of drive gear and sun gear meshing, drive gear corotation or reversal will be along the regional rotary motion of the peripheral tooth portion of sun gear, drive whole fan head luffing motion together, realize automatic yaw. When the weight of the head part is increased and the driving torque of the swing head driver is insufficient, the driving torque can be supplemented by adjusting the torsion of the torsion spring to assist the swing head, so that the torque of the swing head is larger, and the automatic swing head is realized.

When the fan head needs to be manually rotated, the swinging driver can rotate forwards or reversely under the driving of external force, so that when the fan head is rotated by the manual external force, the driving gear can rotate along the central gear, and the manual swinging is realized.

The utility model discloses a yaw mechanism that yaw fan designed makes the fan head can realize the luffing motion under drive gear drive axis of rotation pivoted condition, not only can automatic yaw, also can be at the manual yaw of outage state, and fan head and driver, drive gear synchronous motion simultaneously, the integrative design of three can save space, reduces the whole volume of fan.
