Description

Technical Field

[0001] This utility model relates to a 360-degree oscillating fan and its accessories, particularly a spherical support bearing for a fan and a 360-degree oscillating fan. Background Technology

[0002] Chinese Patent Publication No. CN215633918U, published on January 25, 2022, discloses a dual-motor 360-degree adjustable fan light. It includes a main frame, a light source assembly connected to the main frame, a fan assembly, and a rotating mechanism for driving the fan assembly to rotate and adjust the airflow direction. The rotating mechanism includes an oscillating motor and a transmission assembly. The oscillating motor is mounted on the main frame and connected to the transmission assembly, driving the transmission assembly to rotate. The fan assembly is tilted and connected to the transmission assembly, discharging air in the tilted direction. The transmission assembly drives the fan assembly to rotate, allowing the fan assembly to rotate around a vertical axis to adjust to different directions, thus achieving airflow direction adjustment. To make the fan assembly rotation more stable, the fan light is equipped with a connecting bracket fixedly connected to the fan motor, a hinge ring hinged to the connecting bracket, and a fixed bracket hinged to the hinge ring. However, apart from this, the fan assembly's pivot is suspended, meaning all forces are supported only by the connecting bracket, resulting in poor oscillation balance. Over time, this leads to severe wear on the oscillating components and abnormal noise. Utility Model Content

[0006] Another objective of this invention is to provide a 360-degree oscillating fan with a reasonable structure, stable support, and smooth rotation.

[0007] Another objective of this utility model is achieved as follows: A 360-degree oscillating fan includes a fan assembly, a frame, and an oscillation drive mechanism. The oscillation drive mechanism is mounted on the frame and is used to drive the fan assembly to oscillate and rotate. The fan assembly includes a rotating shaft for connecting to the fan blades. The rotating shaft is connected to the frame via a spherical support bearing. The spherical support bearing includes a spherical sleeve and a ring. The spherical sleeve has a channel extending through both ends therethrough. The rotating shaft passes through the channel and rotates with the channel. The surface of the spherical sleeve has an arcuate surface. The ring is disposed outside the spherical sleeve and moves omnidirectionally with the arcuate surface.

[0008] Another objective of this utility model can also be achieved by the following technical measures: As a more specific embodiment, the collar includes a front collar and a rear collar, both of which are provided with a collar hole. The inner wall of the collar hole is provided with a conical surface or an arc surface. The arc surface of the spherical collar abuts against the conical surface or arc surface and is omnidirectionally movable.

[0009] As a further embodiment, the inner walls of the holes of the front and rear sleeves are tapered, and the front and rear sleeves are spaced apart.

[0010] As a further embodiment, the frame is provided with a bearing seat corresponding to the spherical support bearing. The front and rear rings of the spherical support bearing are disposed in the shaft holes of the bearing seat. The front and rear ends of the bearing seat are respectively provided with a front blocking part and a rear blocking part corresponding to the outer ends of the front and rear rings. The front ring abuts against the inner surface of the front blocking part directly or through an elastic washer, and the rear ring abuts against the inner surface of the rear blocking part directly or through another elastic washer.

[0011] As a further embodiment, the oscillating drive mechanism includes an oscillating drive motor and a crank arm. The oscillating drive motor is mounted on the frame, and the crank arm includes a coupling head and an output head. The central axis of the coupling head and the central axis of the output head form a certain angle. The coupling head is connected to the output shaft of the oscillating drive motor for transmission. The output head is coaxial with the central axis of the rotating shaft and rotates with the fan assembly. The central axis of the coupling head and the central axis of the output head intersect at the center point of the spherical support bearing.

[0012] As a further embodiment, the output shaft of the oscillating drive motor is provided with a horizontal hole, and the coupling head of the crank arm is provided with a relief groove corresponding to the horizontal hole. A horizontal pin is provided in the relief groove and inserted into the horizontal hole. A soft washer is provided between the output head of the crank arm and the opposite surface of the fan assembly, and a locking screw is also provided between the output head and the fan assembly to prevent the crank arm from separating from the fan assembly.

[0013] As a further embodiment, the fan assembly includes a fan drive motor, and the rotating shaft is the rotating shaft of the fan drive motor; the rear end of the rotating shaft is rotatably engaged with the output head of the curved arm; or, the rear end of the rotating shaft is rotatably engaged with the output head of the curved arm, and the front end of the fan drive motor is provided with limit holes or limit rods distributed around the central axis of the rotating shaft, and the front cover is provided with limit rods or limit holes, the outer diameter of the limit rod being smaller than the inner diameter of the limit hole, the limit rod extending into the limit hole, and the limit rod rotating relative to the limit hole when the fan assembly oscillates; or, the rear end of the rotating shaft is rotatably engaged with the output head of the curved arm, and the rear end of the fan drive motor is provided with limit holes or limit rods distributed around the central axis of the rotating shaft, the rear cover is provided with limit rods or limit holes, the outer diameter of the limit rod being smaller than the inner diameter of the limit hole, the limit rod extending into the limit hole, and the limit rod rotating relative to the limit hole when the fan assembly oscillates.

[0014] As a further embodiment, the fan assembly also includes a limiting plate, which is disposed on the fan blade drive motor, and the limiting hole located on the fan blade drive motor is disposed on the limiting plate.

[0015] The beneficial effects of this utility model are as follows: (1) The spherical support bearing of this utility model is provided with two front and rear rings, and the two rings are spaced apart. Therefore, the two rings can have a margin to approach each other. When the two rings approach each other, the friction between the sleeve hole and the arc surface of the spherical sleeve increases slightly, making it difficult for the spherical sleeve to rotate relative to the rings, but it does not affect its swaying.

[0016] (2) The present invention provides a spherical support bearing at the center point of the oscillation rotation of the fan assembly to support the rotating shaft. Without interfering with the rotation of the rotating shaft and the oscillation rotation, it provides support for the fan assembly, thereby reducing the load on the oscillation drive mechanism, making the oscillation smoother and the service life longer.

[0017] (3) In view of the problem that the spherical sleeve and the ring of the spherical bearing are prone to wear when they rotate at high speed, this utility model adopts a shaft and a clearance fit to make the two rotate together and avoid driving the spherical sleeve to rotate. On the other hand, considering that when the shaft swings, it will inevitably have contact with the channel wall of the spherical sleeve, which may drive the spherical sleeve to rotate, the structure of front and rear rings is adopted. In addition, at least one ring is supported by an elastic washer on the outside, so that the ring is close to the spherical sleeve to increase the friction. When the friction between the spherical sleeve and the ring is greater than the friction between the shaft and the channel wall of the spherical sleeve, the spherical sleeve will not be driven to rotate by the shaft.

[0018] (4) The limiting plate and the limiting rod of this utility model have no mechanical connection relationship, but only a positioning and matching relationship, which makes installation more convenient. Moreover, the mechanical stress and wear are small, making it less prone to damage and reducing working noise. Attached Figure Description

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments: Spherical Support Bearing Example 1 See Figure 1 and Figure 2 As shown, a spherical bearing 7 includes a spherical sleeve 73 and rings. The spherical sleeve 73 has a channel 731 extending through both ends and has an arc surface. The rings include a front ring 741 and a rear ring 742, both of which have a bushing 743. The inner wall of the bushing 743 has a tapered surface. The arc surface of the spherical sleeve 73 abuts against the tapered surface (forming a ring-shaped line contact at the contact point to avoid surface wear) and is universally movable. The front ring 741 and the rear ring 742 are spaced apart. Figure 2 As shown at point F. When the spherical sleeve 73 is positioned, both the front sleeve 741 and the rear sleeve 742 can move closer to the spaced-out area, so that the conical surface of the sleeve hole 743 abuts against the arc surface of the spherical sleeve 73.

[0036] Example 2 of spherical support bearing The difference between this and its first embodiment is: see [link to embodiment 1] Figure 3 As shown, the front collar 741 and the rear collar 742 are further provided with an annular sleeve 76. The front and rear ends of the annular sleeve 76 are respectively provided with a front flange and a rear flange. The front collar 741 and the rear collar 742 are limited between the front flange and the rear flange, so that the conical surface of the sleeve hole 743 abuts against the arc surface of the spherical sleeve 73, and so that the front collar 741, the rear collar 742, and the spherical sleeve 73 are combined together.

[0037] Spherical Support Bearing Example 3 The difference between this and its second embodiment is: see [link to embodiment 2] Figure 4 As shown, the front collar 741 abuts against the inner surface of the front flange via an elastic washer 72, and the rear collar 742 abuts directly against the inner surface of the rear flange. The elastic washer 72 is a wave-shaped washer.

The oscillating drive mechanism is mounted on the frame 1 and is used to drive the fan assembly to oscillate and rotate. The fan assembly includes a rotating shaft 21 for connecting to the blades. The rotating shaft 21 is connected to the frame 1 through a spherical support bearing 7. The spherical support bearing 7 includes a spherical sleeve 73 and a ring. The spherical sleeve 73 has a channel 731 passing through both ends of it. The rotating shaft 21 passes through the channel 731 and rotates with the channel 731. The surface of the spherical sleeve 73 has an arc surface. The ring is located outside the spherical sleeve 73 and moves in a universal manner with the arc surface.

[0039] The collar includes a front collar 741 and a rear collar 742. Both the front collar 741 and the rear collar 742 are provided with a sleeve hole 743. The inner wall of the sleeve hole 743 is provided with a conical surface. The arc surface of the spherical sleeve 73 abuts against the conical surface and is omnidirectionally movable.

[0041] Specifically: the frame 1 includes a front cover 11 and a rear cover 12, and the fan assembly is located in the space surrounded by the rear cover 12 and the front cover 11; the oscillating drive motor 3 is mounted on the rear cover 12, and the rear cover 12 is provided with a wire outlet hole 13 corresponding to the periphery of the oscillating drive motor 3, and a second wire binding rod 131 is provided on the wire outlet hole 13; the spherical support bearing 7 is mounted on the front end face of the front cover 11.

[0042] The bearing seat 14 is provided at the center of the front cover 11. The bearing seat 14 has a flange at the front end of the shaft hole, which forms the front blocking part 141. The bearing seat 14 has a connecting hole at the outer periphery of the rear end, and a limit screw is connected to the connecting hole. The top cap of the limit screw protrudes to the rear end of the shaft hole, forming the rear blocking part 71.

[0043] The oscillating drive mechanism includes an oscillating drive motor 3 and a crank arm 5. The oscillating drive motor 3 is mounted on the frame 1. The crank arm 5 includes a coupling head 54 and an output head 56. The central axis of the coupling head 54 and the central axis of the output head 56 form a certain angle. The coupling head 54 is connected to the output shaft 31 of the oscillating drive motor 3. The output head 56 is coaxially arranged with the central axis of the rotating shaft 21 and rotates with the fan assembly. The central axis of the coupling head 54 and the central axis of the output head 56 intersect at the center point of the spherical support bearing 7.

[0044] The output shaft 31 of the oscillating drive motor 3 is provided with a horizontal hole 32. The coupling head 54 of the crank arm 5 is provided with a relief groove 55 corresponding to the horizontal hole 32. A horizontal pin 52 is provided in the relief groove 55 and is inserted into the horizontal hole 32. A soft washer 53 is provided between the output head 56 of the crank arm 5 and the opposite surface of the fan assembly. A locking screw 51 is also provided at the outer end of the output head 56. The screw of the locking screw 51 is screwed into the fan assembly, and the head of the locking screw abuts against the outer end of the output head 56.

[0045] The fan assembly includes a fan drive motor 2, and the rotating shaft 21 is the rotating shaft 21 of the fan drive motor 2. The fan assembly also includes a limiting plate 4, which is disposed on the rear end of the fan drive motor 2. The limiting plate 4 has a shaft head 42 corresponding to the central axis of the rotating shaft 21, and the output head 56 of the crank arm 5 is rotatably engaged with the shaft head 42. The locking screw 51 is connected to the rear end of the shaft head 42, and the soft washer 53 is sleeved on the outside of the shaft head 42.

[0046] Limiting holes 41 are distributed around the central axis of the rotating shaft 21 on the limiting disc 4. A limiting rod 6 is provided on the rear cover 12. The outer diameter of the limiting rod 6 is smaller than the inner diameter of the limiting hole 41. The limiting rod 6 extends into the limiting hole 41. When the fan assembly oscillates, the limiting rod 6 rotates relative to the limiting hole 41. The limiting disc 4 is disc-shaped, and the shaft head 42 is provided at its center.

[0047] Three limiting holes 41 are provided, and the limiting holes 41 are evenly distributed around the center of the rotating shaft 21. The size, shape, and position distribution of the limiting holes 41 are determined according to the oscillation trajectory of the fan drive motor 2, and the limiting holes 41 change with the distance from the oscillation center point along the axis of the rotating shaft 21. Since the entire fan assembly is rotated and engaged with the output head 56 of the crank arm 5 of the oscillation drive mechanism, without the limiting effect of the limiting holes 41 and the limiting rod 6, the fan assembly may rotate 360 ​​degrees around the output head 56 as the axis during the oscillation process, causing the wires to become entangled. By setting the above-mentioned limiting structure, this situation can be avoided.

[0048] The surface of the limiting plate 4 is provided with a wire hole 44, and the side wall of the wire hole 44 is provided with a wire binding rod 43.

[0049] The fan assembly also includes a control circuit board 22, which is located at the rear end of the housing of the fan drive motor 2 and in front of the limiting plate 4. The control circuit board 22 is provided with wires. The wires first pass through the wire hole 44 on the limiting plate 4 and are fixed to the binding rod 43 by cable tie (or other fasteners). Then, the wires corresponding to the limiting plate 4 and the outlet hole 13 are wound into a spiral buffer section. Finally, the wires pass out of the outlet hole 13 and are fixed to the second binding rod 131 of the outlet hole 13, which is not shown in the figure.

[0050] Example 2 of 360-degree oscillating fan The difference from Example 1 is as follows: See Figures 13 to 16 As shown, the rear end 211 of the rotating shaft is rotatably engaged with the output head 56 of the crank arm 5, the locking screw 51 is connected to the rear end 211 of the rotating shaft, and the soft washer 53 is sleeved on the outside of the rotating shaft.

[0051] The fan assembly also includes a limiting disk 4, which is located on the front end of the fan drive motor 2, and the rotating shaft 21 passes through the center of the limiting disk 4.

[0052] Limiting holes 41 are distributed around the central axis of the rotating shaft 21 on the limiting plate 4. A limiting rod 6 is provided on the front cover 11. The outer diameter of the limiting rod 6 is smaller than the inner diameter of the limiting hole 41. The limiting rod 6 extends into the limiting hole 41. When the fan assembly shakes, the limiting rod 6 rotates relative to the limiting hole 41.

[0053] Three limiting holes 41 are provided, and the limiting holes 41 are evenly distributed around the center of the rotating shaft 21. The size, shape and position distribution of the limiting holes 41 are determined according to the trajectory of the fan drive motor 2 oscillating. The limiting holes 41 change with the distance from the axis of the rotating shaft 21 to the center point of the oscillation.

[0054] The fan assembly also includes a control circuit board 22, which is located at the front end of the housing of the fan drive motor 2 and behind the limiting plate 4.
