In the description of the present invention, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.
Referring to fig. 1 and 2, a head shaking mechanism 10 in an embodiment includes a mounting seat 100 and a rotating member 200, the rotating member 200 is rotatably disposed on the mounting seat 100, an air outlet main body (not shown) is connected with the rotating member 200, and the rotating member 200 drives the air outlet main body to rotate so as to realize air outlet of the air outlet main body at multiple angles.
Further, referring to fig. 3, 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, and the first state may be a state in which the rotating member 200 is in operation. Referring to fig. 4, when the rotating member 200 is in the second state, the rotating member 200 and the mounting base 100 can be separated, and at this time, the rotating member 200 and the mounting base 100 are in a state that they can be separated from each other when they want to be separated, but it is not necessary to say that the rotating member 200 is separated from the supporting base; in another aspect, when the rotating member 200 is in the second state, the rotating member 200 may be in an initial state of being mounted on the mounting base 100.
It is noted that when the rotating member 200 is in the first state, the rotating member 200 is in a limited engagement with the mounting base 100, and the rotating member 200 and the mounting base 100 are in a limited state in the longitudinal direction, at this time, the rotating member 200 cannot move upward in a direction overcoming the gravity of the rotating member 200 to be separated from the mounting base 100. Rather than the first state, the rotating member 200 and the mounting base 100 are in a locked state, because the rotating member 200 still needs to rotate relative to the mounting base 100 when the rotating member 200 is in a limited fit with the mounting base 100.
Referring to fig. 3, when a fan needs to be moved, the rotating member 200 can be in a first state, and the rotating member 200 is in limited 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, so that when a cooling fan is moved, under the action of external force, the rotating member 200 can support the mounting seat 100 and is always moved up together with the mounting seat 100, thereby avoiding the breakage of the connection parts between other components and the mounting seat 100 due to the gravity of the mounting seat 100, and further improving the reliability of the fan; referring to fig. 4, when the rotating member 200 and the mounting base 100 need to be separated, the rotating member 200 is only required to be driven to be in the second state, and the rotating member 200 and the mounting base 100 are in the separable state at this time, so that the rotating member 200 is separated from the mounting base 100.
Referring to fig. 4, in one embodiment, the rotating member 200 is provided with a second mounting hole 210, the mounting base 100 is provided with a positioning portion 110, and the positioning portion 110 is in clearance fit with the second mounting hole 210, so that when the rotating member 200 rotates, the second 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 second mounting hole 210 along an extending direction of the second mounting hole 210. Referring back to fig. 4, when the rotating member 200 rotates to the separation 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 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; based on this, it means that when the rotating member 200 needs to be detached from the mounting base 100, the rotating member 200 needs to be driven to rotate only until the separation position 214 contacts the positioning portion 110, or when the rotating member 200 is initially mounted with the mounting base 100, the rotating member 200 needs to be mounted on the mounting base 100 only by just making the separation position 214 contact the positioning portion 110; when the rotating member 200 is in the working state, in the present embodiment, the rotating member 200 is in the first state, and only the rotating member 200 needs to be driven to rotate so that the positioning portion 110 is always located between the locking position 212 and the separating position 214.
Referring to fig. 5, in the present embodiment, the second mounting hole 210 is an arc hole, and the positioning portion 110 has a certain limiting function, and the angle of the arc hole defines the rotation angle of the rotating member 200.
An alternative implementation of the positive engagement between the rotator 200 and the mount 100 will be described below in connection with an example.
Referring to fig. 8, in one embodiment, the mounting base 100 is provided with a first limiting portion 120 and a clearance portion 130 adjacent to the first limiting portion 120, and the rotating member 200 is provided with a second limiting portion 230; referring back to fig. 4, when the rotating member 200 is in the second state, the second limiting portion 230 is inserted into the space-avoiding portion 130; referring to fig. 7 and 8, when the rotating member 200 is in the first state, at least a portion of the second limiting portion 230 is separated from the space portion 130 and rotates to be in limiting engagement with the first limiting portion 120. In this way, it can be understood that, in the initial state, the rotating member 200 is mounted on the mounting base 100 by inserting the second limiting portion 230 into the space avoiding portion 130. When the rotating member 200 is required to be in the first state, or when the rotating member 200 is required to drive the air outlet main body to rotate, at least part of the second limiting portion is required to be driven to leave the clearance portion 130 to rotate to be in limiting fit with the first limiting portion 120, so that the rotating member 200 can rotate and also can be limited with the mounting seat 100.
Optionally, referring to fig. 8, the space-avoiding portion 130 is a plugging notch, the first limiting portion 120 is a limiting protrusion, and the second limiting portion 230 is a limiting recess; referring to fig. 4, when the rotating member 200 is in the second state, the limiting recess 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 limit fit with the mounting base 100 through concave-convex fit of the limit concave portion and the limit convex portion, and at least part of the limit convex portion is disposed in the concave space of the limit 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 piece 200 is lifted, the limit concave part contacts with the limit convex part and supports the mounting seat 100, thereby avoiding the separation between the rotating piece 200 and the mounting seat 100,
In order to ensure that when the rotating member 200 is in the first state, the rotating member 200 and the mounting seat 100 are always in a state of being in a limit fit, at this time, the rotating member 200 can rotate relative to the mounting seat 100, but under the action of external force, the rotating member 200 can support the mounting seat 100. In this embodiment, the angle between the first line between the separation position 214 and the center of the arc hole and the second line between the locking 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 > a2. Thus, when the rotating member 200 reciprocally rotates within the rotation angle a2, as a1 > a2, the positioning portion 110 is always located between the locking portion 212 and the separating portion 214, that is, when the rotating member 200 is in the first state, the rotating member 200 and the mounting seat 100 are in a limit fit, so that the rotating member 200 can support the mounting seat 100 in the gravity direction of the mounting seat 100, and further, breakage of the connection portion between other components and the mounting seat 100 due to gravity of the mounting seat 100 in the process of carrying is avoided.

At this time, when the driving assembly 300 drives the rotating member 200 to rotate, the rotating member 200 is in the first state, and the rotating member 200 is in a 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. Specifically, the driving assembly 300 drives the rotation member 200 to reciprocally rotate 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, crank 320 and linkage 330 form a "linkage". When the motor 310 is running, the crank 320 is driven to rotate, the crank 320 drives the connecting rod 330 to rotate, and because the connecting rod 330 is connected with the mounting seat 100, the mounting seat 100 is generally fixed, and therefore, 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 seat 100.
In other embodiments, the driving assembly 300 may be other rotation power sources, and the rotation power sources only need to drive the rotation member 200 to rotate, which is not described herein.
