Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

Referring to fig. 1 and 2, an embodiment of an oscillating mechanism 10 includes a mounting base 100 and a rotating member 200, the rotating member 200 is rotatably disposed on the mounting base 100, an air outlet main body (not shown) is connected to the rotating member 200, and the rotating member 200 drives the air outlet main body to rotate to realize air outlet at multiple angles.

Further, the rotating member 200 includes a first state and a second state, referring to fig. 3, when the rotating member 200 is in the first state, the rotating member 200 is in a spacing fit with the mounting base 100, so that the rotating member 200 can support the mounting base 100 in the gravity direction of the mounting base 100; the first state may be a state in which the rotation member 200 is operated. Referring to fig. 4, when the rotating member 200 is in the second state, the rotating member 200 can be separated from the mounting base 100, and at this time, the rotating member 200 and the mounting base 100 are in a state that they can be separated as desired, that is, the rotating member 200 is not necessarily separated from the supporting base; from another perspective, when the rotating member 200 is in the second state, the rotating member 200 may be just mounted on the mounting base 100 in the initial state.

It should be noted that when the rotating member 200 is in the first state, the rotating member 200 is in a limit fit with the mounting seat 100 so that the rotating member 200 can support the mounting seat 100 in the gravity direction of the mounting seat 100, which means that the rotating member 200 and the mounting seat 100 are in a limit state in the longitudinal direction, and the rotating member 200 cannot move upward to separate from the mounting seat 100 in a direction against the gravity of the rotating member 200. Rather than in the first state, the rotation element 200 and the mounting base 100 are in a locked state, because the rotation element 200 still needs to rotate relative to the mounting base 100 when the rotation element 200 is in limit fit with the mounting base 100.

Referring to fig. 3, when the fan needs to be moved, the rotating member 200 may be in the first state, and the rotating member 200 is in limit fit with the mounting base 100, so that the rotating member 200 can support the mounting base 100 in the gravity direction of the mounting base 100, and thus when the cooling fan is moved, under the action of an external force, the rotating member 200 can support the mounting base 100 and is always moved together with the mounting base 100, thereby preventing the connection parts between other components and the mounting base 100 from being broken due to the self gravity of the mounting base 100, and further improving the reliability of the fan; referring to fig. 4, when it is required to separate the rotating member 200 from the mounting base 100, it is only necessary to drive the rotating member 200 to be in the second state, and at this time, the rotating member 200 and the mounting base 100 are in a separable state, so that the rotating member 200 is separated from the mounting base 100.

Referring to fig. 4, in one embodiment, the rotating member 200 has a first mounting hole 210, the mounting base 100 has a positioning portion 110, and the positioning portion 110 is in clearance fit with the first mounting hole 210, at this time, when the rotating member 200 rotates, the first mounting hole 210 can move relative to the positioning portion 110.

Further, referring to fig. 5, a locking position 212 and a separating position 214 are disposed along an inner wall of the first mounting hole 210 in an extending direction of the first mounting hole 210. Referring back to fig. 4, when the rotating member 200 rotates to the separating position 214 to contact the positioning portion 110, the rotating member 200 can be separated from the mounting base 100; referring to fig. 6 and 7, when the positioning portion 110 is located between the locking position 212 and the separating position 214, the rotating member 200 is in a limiting fit with the mounting base 100, so that the rotating member 200 can support the mounting base 100 in the gravity direction of the mounting base 100; based on this, it means that when the rotating member 200 needs to be detached from the mounting base 100, the rotating member 200 only needs to be driven to rotate until the separating position 214 contacts the positioning portion 110, or, when the rotating member 200 and the mounting base 100 are initially mounted, the rotating member 200 can be mounted on the mounting base 100 only by just making the separating position 214 contact the positioning portion 110; when the rotation member 200 is in the operating state, in the present embodiment, the rotation member 200 is in the first state, and it is only necessary to drive the rotation member 200 to rotate so that the positioning portion 110 is always located between the locking position 212 and the release position 214.

Referring to fig. 5, in the present embodiment, the first mounting hole 210 is an arc-shaped hole, the positioning portion 110 has a certain limiting effect, and the angle of the arc-shaped hole defines the rotation angle of the rotating member 200.

An alternative embodiment of the limit fit between the rotatable member 200 and the mounting base 100 will be described with reference to the following examples.

Referring to fig. 8, in one embodiment, the mounting base 100 has a second position-limiting portion 120 and a space-avoiding portion 130 adjacent to the second position-limiting portion 120, and the rotating member 200 has a third position-limiting portion 230; referring back to fig. 4, when the rotating member 200 is in the second state, the third position-limiting portion 230 is inserted into the clearance portion 130; referring to fig. 7 and 8, when the rotating member 200 is in the first state, at least a portion of the third position-limiting portion 230 leaves the clearance portion 130 and rotates to be in position-limiting engagement with the second position-limiting portion 120, so that the third position-limiting portion 230 can support the second position-limiting portion 120 in the gravity direction of the mounting base 100. As described above, in the initial state, the rotating member 200 is mounted on the mounting base 100 by inserting the third stopper 230 into the recess 130. When the rotation member 200 needs to be in the first state, or the rotation member 200 needs to drive the air outlet main body to rotate, at this time, only at least part of the third limiting portion needs to be driven to leave the escape portion 130 and rotate to be in limiting fit with the second limiting portion 120, so that the rotation member 200 can rotate and can be limited with the mounting base 100.

Optionally, referring to fig. 8, the clearance portion 130 is an insertion notch, the second limiting portion 120 is a limiting convex portion, and the third limiting portion 230 is a limiting concave portion; referring to fig. 4, when the rotating member 200 is in the second state, the limiting concave portion is inserted into the insertion notch; referring to fig. 3, 6 and 7, when the rotating member 200 is in the first state, the rotating member 200 is in a position-limiting fit with the mounting base 100 through the concave-convex fit of the position-limiting concave portion and the position-limiting convex portion, and at least a portion of the position-limiting convex portion is disposed in the concave space of the position-limiting concave portion. Wherein at least part of the limit convex part is arranged in the concave space of the limit concave part, which means that the limit concave part covers at least part of the limit convex part, when the rotating member 200 is lifted, the limit concave part contacts with the limit convex part and supports the mounting base 100, thereby avoiding the separation between the rotating member 200 and the mounting base 100,

in order to ensure that the rotating member 200 is always in a position-limited engagement with the mounting base 100 when the rotating member 200 is in the first state, the rotating member 200 can rotate relative to the mounting base 100, but the rotating member 200 can support the mounting base 100 under the action of external force. In this embodiment, an angle of a first line between the separation position 214 and the center of the arc hole and a second line between the lock position 212 and the center of the arc hole is a1, and when the rotating member 200 is in the first state, the rotating angle of the rotating member 200 is a2, where a1 > a 2. In this way, when the rotating member 200 rotates back and forth within the rotation angle of a2, since a1 > a2, the positioning portion 110 is always located between the locking position 212 and the separating position 214, that is, when the rotating member 200 is in the first state, it can be ensured that the rotating member 200 is in spacing fit with the mounting base 100 so that the rotating member 200 can support the mounting base 100 in the gravity direction of the mounting base 100, and further the rotating member 200 supports the mounting base 100 under the action of external force, thereby avoiding the fracture of the connecting portion between other components and the mounting base 100 due to the self gravity of the mounting base 100 during the transportation process.

On the basis of the foregoing embodiment, referring to fig. 6 and 9, the oscillating mechanism 10 further includes a driving assembly 300, the driving assembly 300 is connected to the rotating member 200, and the driving assembly 300 is configured to drive the rotating member 200 to rotate so as to make the positioning portion 110 between the locking position 212 and the separating position 214. At this time, when the driving assembly 300 drives the rotating member 200 to rotate, at this time, the rotating member 200 is in the first state, and the rotating member 200 is in spacing fit with the mounting base 100, so that the rotating member 200 can support the mounting base 100 in the gravity direction of the mounting base 100, and further the rotating member 200 supports the mounting base 100 under the action of external force. Specifically, the driving assembly 300 drives the rotation member 200 to rotate back and forth within the angle a 2.

Alternatively, referring to fig. 6 and 9, the driving assembly 300 includes a motor 310, a crank 320 and a connecting rod 330, the motor 310 is connected to the rotating member 200, a power output end of the motor 310 is connected to one end of the crank 320, the other end of the crank 320 is connected to one end of the connecting rod 330, and the other end of the connecting rod 330 is connected to the positioning portion 110. The motor 310, the crank 320 and the connecting rod 330 constitute a "link mechanism". When the motor 310 operates, the crank 320 is driven to rotate, the crank 320 drives the connecting rod 330 to rotate, and since the connecting rod 330 is connected to the mounting base 100, the mounting base 100 is generally fixed, when in use, the connecting rod 330 applies a force to the crank 320 to drive the motor 310 to drive the rotating member 200 to rotate relative to the mounting base 100.

In other embodiments, the driving assembly 300 may also be another rotation power source, and the rotation power source only needs to drive the rotation member 200 to rotate, which is not described herein.

Thus, the rotating portion 220 is configured as a wear-resistant shaft, and at this time, depending on the wear-resistant characteristic of the wear-resistant shaft, when the wear-resistant shaft is directly matched with the second mounting hole 140, the wear of the wear-resistant shaft can be reduced; alternatively, the wear-resistant shaft may be made of a wear-resistant material such as POM (Polyoxymethylene resin) or Peek (polyetheretherketone), and the mounting seat 100 may be made of ABS (Acrylonitrile Butadiene Styrene) or PP (polypropylene).
