As shown in fig. 1 and 3, the oscillating mechanism according to the embodiment includes: a fixed member 100, a moving head assembly 200, and an eccentricity correction assembly 300.
Specifically, the fixing member 100 is fixedly provided on the fan body, and the fixing member 100 has a fixed gear 110; the oscillating assembly 200 includes a driving source 210 and a driving gear 220, the driving source 210 is fixedly disposed on the fan head, the driving source 210 has a driving shaft 211, the driving gear 220 is connected to the driving shaft 211, and the driving gear 220 is engaged with the fixed gear 110; the eccentricity correction assembly 300 includes a mounting shaft 310 and an eccentricity correction gear 320 sleeved on the mounting shaft 310, wherein the mounting shaft 310 is disposed on the driving source 210 and spaced from the driving shaft 211, the eccentricity correction gear 320 is engaged with the fixed gear 110, and the eccentricity correction gear 320 is spaced from the driving gear 220.
More specifically, the eccentricity correction gear 320 and the driving gear 220 are uniformly arranged in the circumferential direction of the fixed gear 110.
In the above-described head shaking mechanism, since the driving gear 220 of the head shaking assembly 200 is connected to the driving shaft 211 of the driving source 210, the driving gear 220 can be driven to rotate by the driving source 210, and since the driving gear 220 is engaged with the fixed gear 110 of the fixture 100, the driving gear 220 can perform engagement transmission on the fixed gear 110 in a case where the driving gear 220 is driven to rotate, so that the driving gear 220 can drive the driving source 210 to rotate around the central axis of the fixed gear 110. Since the driving source 210 is fixedly provided to the fan head, the driving source 210 can rotate the fan head about the central axis of the fixed gear 110 in a case where the driving source 210 rotates about the central axis of the fixed gear 110. Since the fixing member 100 is fixedly installed on the fan body, the fan head can swing around the fan body when the fan head rotates around the central axis of the fixed gear 110 of the fixing member 100, thereby realizing the oscillating motion of the fan.
In addition, during the meshing transmission between the driving gear 220 and the fixed gear 110, the driving gear 220 may apply a certain centrifugal force to the fixed gear 110 due to the gravity of the fan head, so that the fixed gear 110 is easily eccentric. Since the eccentric correction gear 320 of the eccentric correction assembly 300 is sleeved on the mounting shaft 310 disposed on the driving source 210 and the eccentric correction gear 320 is engaged with the fixed gear 110, the eccentric correction gear 320 can be engaged with the fixed gear 110 along with the driving gear 220 in the process of engaging and driving the driving gear 220 and the fixed gear 110. Since the mounting shaft 310 is spaced apart from the driving shaft 211 and the eccentricity correction gear 320 is spaced apart from the driving gear 220, the eccentricity correction gear 320 does not interfere with the engagement between the driving gear 220 and the fixed gear 110 during the engagement transmission between the driving gear 220 and the fixed gear 110, and the eccentricity correction gear 320 can apply a reverse centrifugal force opposite to the driving gear 220 to the fixed gear 110 to offset the centrifugal force applied to the fixed gear 110 by the driving gear 220, so that the central axis of the fixed gear 110 is corrected. Further, the phenomenon that the transmission between the driving gear 220 and the fixed gear 110 is unstable due to the eccentric phenomenon can be prevented, thereby improving the stability of the fan when shaking the head.

Specifically, the driving source 210 is a synchronous motor, which has the advantage of large load bearing and can drive a heavy fan head to swing relative to the fan body.
Since one end of the mounting shaft 310 is fixedly coupled to the driving source 210, the mounting shaft 310 can rotate about the central axis of the fixed gear 110 along with the driving source 210 when the driving gear 220 rotates the driving source 210 about the central axis of the fixed gear 110. Since the eccentric correction gear 320 is rotatably sleeved on the mounting shaft 310, the mounting shaft 310 can drive the eccentric correction gear 320 to rotate around the central axis of the fixed gear 110. Since the eccentricity correction gear 320 is engaged with the fixed gear 110, when the eccentricity correction gear 320 rotates around the central axis of the fixed gear 110, the eccentricity correction gear 320 can be engaged with the fixed gear 110 to generate a reverse centrifugal force opposite to the centrifugal force applied by the driving gear 220 to the fixed gear 110, thereby canceling the centrifugal force applied by the driving gear 220 to the fixed gear 110, correcting the central axis of the fixed gear 110, avoiding the eccentricity of the fixed gear 110, and further improving the stability of the shaking head structure.
As shown in fig. 1 to 3, in one embodiment, there are a plurality of mounting shafts 310, the driving shaft 211 is spaced apart from the plurality of mounting shafts 310, and one end of each mounting shaft 310 is fixedly connected to the driving source 210; the eccentric correction gears 320 are provided in plurality, the driving gear 220 and the eccentric correction gears 320 are arranged at intervals, the eccentric correction gears 320 are sleeved on the mounting shafts 310 in a one-to-one correspondence manner, each eccentric correction gear 320 is rotatably connected with each mounting shaft 310, and each eccentric correction gear 320 is meshed with the fixed gear 110.
Specifically, the driving gear 220 and the plurality of eccentricity correction gears 320 are uniformly disposed on the fixed gear 110 in the circumferential direction of the fixed gear 110.
In this way, when the driving gear 220 and the plurality of eccentricity correction gears 320 are engaged with the fixed gear 110, a plurality of reverse centrifugal forces opposite to the centrifugal force applied by the driving gear 220 to the fixed gear 110 can be generated, and the centrifugal force applied by the driving gear 220 to the fixed gear 110 can be better balanced by the plurality of reverse centrifugal forces, so that the oscillating mechanism has stronger stability, and the stability of the fan during oscillating is further improved.

Since the gear bracket 330 is fixedly coupled to an end of the driving source 210 near the eccentricity correction gear 320 and an end of the mounting shaft 310 is fixedly coupled to a side of the gear bracket 330 near the eccentricity correction gear 320, the eccentricity correction gear 320 can be coupled to the gear bracket 330, and further the eccentricity correction gear 320 is fixed to the driving source 210 through the gear bracket 330. The eccentric correction gear 320 is fixed on the driving source 210 through the gear bracket 330, so that the machining process of the oscillating mechanism can be simplified, and the oscillating mechanism can be conveniently installed.
As shown in fig. 1 and 2, in one embodiment, the central axis of the fixed gear 110 is arranged along the left-right direction of the fan body, one end of the fixed gear 110 is fixedly connected with the fan body, the other end of the fixed gear 110 is rotatably connected with the fan body, and the fan body swings in the vertical direction with respect to the fan body in the case that the driving gear 220 performs meshing transmission with the fixed gear 110.
Specifically, in one of the embodiments, the fixed gear 110 is fixedly provided on one of the left ends of the fan body.
Since one end of the fixed gear 110 is fixedly connected to the fan body and the other end is rotatably connected to the fan head, the fan head can swing with respect to the fan body when the fan head rotates with respect to the fixed gear 110. Since the central axis of the fixed gear 110 is disposed along the left and right direction of the fan body, when the driving gear 220 is engaged with the fixed gear 110 on the fixed gear 110, the fan head fixedly connected to the driving gear 220 can rotate around the central axis of the fixed gear 110 along with the driving gear 220. When the driving gear 220 is driven to be engaged on the fixed gear 110 in a counterclockwise direction, the fan head swings in a counterclockwise direction with respect to the fan body, and when the driving gear 220 is driven to be engaged on the fixed gear 110 in a clockwise direction, the fan head swings in a clockwise direction with respect to the fan body, thereby realizing a vertical swing motion of the fan head with respect to the fan body.
As shown in fig. 1 and 2, in one embodiment, the oscillating mechanism further includes an oscillating bracket 400 fixedly connected to the fan head, the oscillating bracket 400 is provided with an accommodating cavity 410 and a mounting through hole 420 communicating with the accommodating cavity 410, the oscillating assembly 200 and the eccentric correcting assembly 300 are both disposed in the accommodating cavity 410, the fixed gear 110 is disposed in the mounting through hole 420, and the oscillating bracket 400 is rotatable relative to the fixed gear 110.
Specifically, in one embodiment, the moving head support 400 includes a mounting portion 430 and a connecting portion 440 fixedly connected to the mounting portion 430, the receiving cavity 410 and the mounting through hole 420 are formed on the mounting portion 430, the connecting portion 440 is formed on a side of the mounting portion 430 close to the driving source 210, the connecting portion 440 can cover the mounting portion 430 to cover the moving head assembly 200 and the eccentricity correction assembly 300 in the receiving cavity 410 of the mounting portion 430, and the connecting portion 440 is fixedly connected to the fan head.
More specifically, in one embodiment thereof, the mounting through-hole 420 is provided at a side of the mounting portion 430 adjacent to the fixed gear 110.
Further, in one embodiment, the driving source 210 and the gear holder 330 are fixed on the inner wall of the housing.
So, the subassembly 200 and the eccentric subassembly 300 of correcting of shaking the head can be fixed and the protection by the support 400 of shaking the head, because the support 400 and the fan aircraft nose fixed connection of shaking the head, and the support 400 of shaking the head is rotatable for fixed gear 110, consequently when the support 400 of shaking the head rotates for the fixed bolster, the support 400 of shaking the head can drive the fan aircraft nose and rotate to reach the fan aircraft nose for the purpose of fan fuselage wobbling. Since the driving source 210 and the gear holder 330 are fixed on the inner wall of the fixed gear 110, when the driving gear 220 and the eccentric correcting gear 320 are engaged with each other and driven by the fixed gear 110, the driving gear 220 and the eccentric correcting gear 320 can drive the swing bracket 400 to rotate by the driving source 210 and the gear holder 330, thereby achieving the purpose of rotating the swing bracket 400 relative to the fixed gear 110.
When the driving gear 220 is driven to be engaged with the fixed gear 110 in the counterclockwise direction, the eccentric correcting gear 320 can be engaged with the driving gear 220 in the counterclockwise direction on the fixed gear 110, at this time, the driving gear 220 and the eccentric correcting gear 320 can drive the driving source 210 and the gear bracket 330 to swing in the counterclockwise direction around the central axis of the fixed gear 110, so as to drive the swing bracket 400 to swing in the counterclockwise direction around the central axis of the fixed gear 110, and finally, the swing bracket 400 drives the fan head to swing in the counterclockwise direction around the central axis of the fixed gear 110, so as to achieve the purpose that the fan head swings in the counterclockwise direction relative to the fan body. When the driving gear 220 is driven to be meshed with the fixed gear 110 clockwise, the eccentric correcting gear 320 can be meshed with the driving gear 220 on the fixed gear 110 clockwise, at this time, the driving gear 220 and the eccentric correcting gear 320 can drive the driving source 210 and the gear bracket 330 to swing clockwise around the central axis of the fixed gear 110, so as to drive the swing bracket 400 to swing clockwise around the central axis of the fixed gear 110, and finally, the swing bracket 400 drives the fan head to swing clockwise around the central axis of the fixed gear 110, so that the purpose that the fan head swings clockwise relative to the fan body is achieved. The purpose of swinging the fan head relative to the fan body is further achieved.
As shown in fig. 1 and 3, in one embodiment, the fixed gear 110 is an internal gear, the driving gear 220 and the eccentricity correction gear 320 are external gears, the driving gear 220 and the eccentricity correction gear 320 are disposed in the fixed gear 110, and the driving gear 220 and the eccentricity correction gear 320 are engaged with the fixed gear 110.
Since the driving gear 220 and the eccentricity correction gear 320 are both disposed in the fixed gear 110 and the driving gear 220 and the eccentricity correction gear 320 are both engaged with the fixed gear 110, the volume of the swing mechanism can be reduced, and the overall volume of the fan can be reduced. In addition, the internal gear transmission can provide a stronger stability to the driving gear 220 and the eccentricity correction gear 320 when they are transmitted to the fixed gear 110, and can prevent the driving gear 220 and the eccentricity correction gear 320 from sliding in the axial direction of the fixed gear 110, thereby preventing the occurrence of the disengagement of the gears.
As shown in fig. 1 and 2, in one embodiment, the fan further includes a sensing assembly 500, and the sensing assembly 500 is used for limiting the swing angle of the fan head relative to the fan body.
Specifically, in one embodiment, the sensing assembly 500 includes a first sensing element 510 and a second sensing element 520, the first sensing element 510 is disposed on the moving head assembly 200, the second sensing element 520 is disposed on the fixing element 100, and the first sensing element 510 is electrically connected to the driving source 210;
when the second sensing member 520 is in contact with or spaced within a predetermined distance from the first sensing member, the first sensing member 510 is used to transmit a reverse driving signal to the driving source 210.
More specifically, the first sensing member 510 is a hall switch, and the second sensing member 520 is an induction magnet block, it should be noted that the hall switch can be triggered when the magnetic field intensity around the hall switch is stronger.
More specifically, when the driving source 210 rotates reversely for a certain time, the driving source 210 can automatically perform the normal rotation.
In this way, when the second sensing member 520 is in contact with or spaced apart from the first sensing member by a predetermined distance, the first sensing member 510 can transmit a reverse driving signal to the driving source 210, and the driving source 210 drives the driving gear 220 to be engaged with the fixed gear 110 in a counterclockwise direction, and the eccentricity correction gear 320 can be engaged with the driving gear 220 on the fixed gear 110 in a counterclockwise direction. At this time, the driving gear 220 and the eccentric correcting gear 320 can drive the moving head assembly 200 and the eccentric correcting assembly 300 to swing counterclockwise around the central axis of the fixed gear 110, so as to drive the fan head to swing counterclockwise around the central axis of the fixed gear 110, thereby achieving the purpose that the fan head swings counterclockwise relative to the fan body.
After the driving source 210 rotates reversely for a certain time, the driving source 210 starts to rotate forward, at this time, the driving source 210 drives the driving gear 220 to mesh on the fixed gear 110 in a clockwise direction, the eccentric correction gear 320 can mesh on the fixed gear 110 in a clockwise direction along with the driving gear 220, at this time, the driving gear 220 and the eccentric correction gear 320 can drive the oscillating assembly 200 and the eccentric correction assembly 300 to swing clockwise around the central axis of the fixed gear 110, so as to drive the fan head to swing clockwise around the central axis of the fixed gear 110, thereby achieving the purpose that the fan head swings clockwise relative to the fan body. The purpose of swinging the fan head relative to the fan body is further achieved.
The working principle of the oscillating mechanism is as follows: in the case that the fixed gear 110 is located at the left end of the fan body, the initial position of the fan head is located at the horizontal position, and the driving source 210 starts to rotate forward after rotating backward for 13s, at this time, the first sensing member 510 is spaced apart from the second sensing member 520 within a predetermined distance, the first sensing member 510 transmits a reverse driving signal to the driving source 210, at this time, the driving source 210 drives the driving gear 220 to be engaged on the fixed gear 110 in the counterclockwise direction, and the eccentricity correction gear 320 can be engaged on the fixed gear 110 in the counterclockwise direction along with the driving gear 220. At this time, the driving gear 220 and the eccentric correcting gear 320 can drive the moving head assembly 200 and the eccentric correcting assembly 300 to swing counterclockwise around the central axis of the fixed gear 110, i.e., drive the fan head to swing upward around the central axis of the fixed gear 110, so that the fan head can swing upward in a vertical direction with respect to the fan body. When the driving source 210 starts the forward rotation after the reverse rotation for 13s, at which time the driving source 210 drives the driving gear 220 to be engaged on the fixed gear 110 in the clockwise direction, the eccentricity correction gear 320 can be engaged with the driving gear 220 on the fixed gear 110 in the clockwise direction. At this time, the driving gear 220 and the eccentric correcting gear 320 can drive the moving head assembly 200 and the eccentric correcting assembly 300 to swing clockwise around the central axis of the fixed gear 110, that is, drive the fan head to swing downward around the central axis of the fixed gear 110, so that the fan head can swing downward in the vertical direction with respect to the fan body. So that the fan head can swing up and down in the vertical direction with respect to the fan body.
A fan according to an embodiment includes: the fan comprises a fan body, a fan head and the oscillating mechanism.
