Because driving mechanism 1 energising is short to the time compole required than uniform rotation from state of rest, start-up course has bigger acceleration, this acceleration will cause the interaction of the non-fixed portions of driving mechanism 1 drive because of power, produce relative movement, use this principle, non-fixed portions operation ring track 30 is carried out structural design, make fan component 2 when just changeing, movable ball 322 falls in the ball hole 300 adjacent with fixing ball 320, thereby cause the off-centre of shake unit 3, realize that fan rotates and vibrating alert.During fan component 2 counter-rotating, movable ball 322 falls in the ball hole 300 with fixing ball 320 symmetries, and shake unit 3 keeps symmetry about axle, and barycenter has only fan to rotate and do not have vibration on axle.
The vibration fan below will be described in detail in detail realize that when just changeing the fan heat radiation adds vibrating alert, the working principle of only dispelling the heat during counter-rotating.Please one by one with reference to Fig. 2 A, Fig. 2 B, Fig. 2 C, Fig. 2 D, Fig. 3, Fig. 4.
Fig. 2 A is for just changeing the symmetrical momentary status schematic representation of the position of movable ball 322 in ball hole 300 when starting and fixing ball 320, below this transient process of detailed description.Original state, fixedly ball 320 falls among the ball hole 300a, and movable ball 322 falls among the ball hole 300b.When driving mechanism 1 is just changeing startup, quicken to rotate moment, because of movable ball 322 is in state of rest temporarily, movable ball 322 has relative movement with ring track 30, the left wall of ball hole 300 will produce interaction force with movable ball 322, each point on the ball hole 300 left walls all has along the active force of ball hole normal direction movable ball 322, whole left wall is to can being decomposed into joint efforts along the normal component of force Fn and the tangential component Ft of axle that movable ball 322 produces, and the startup acceleration of fan is big more, and these two component are also big more.Wherein tangential component Ft except that overcome friction, possible gravity the component of this direction, to make movable ball 322 along the tangential circular movement of doing acceleration of axle, normal component of force removes overcome friction, required circular motion centripetal force (when fan has just rotated, this power is very little), possible gravity is outside the component of this direction, to make movable ball 322 along method of principal axes to doing accelerated motion, this motion will make movable ball 322 break away from the bottom of ball hole 300b.Along with the bottom of movable ball 322 away from ball hole 300b, movable ball 322 weakens gradually with the interaction force of ball hole 300b, but because inertia, movable ball 322 will be along method of principal axes to moving, up to breaking away from ball hole 300b fully.At this moment, movable ball 322 has entered ring track 30, there has not been interaction force with ball hole 300b, owing to there has not been the personal component Ft of ball hole 300b, movable ball 322 no longer tangentially makes to quicken circular movement at this moment, and fan still continues to quicken to rotate, because of track more smooth, so the suffered frictional force of movable ball 322 deficiency far away makes movable ball 322 quicken synchronously with ring track 30, so produce relative movement, be that movable ball 322 relative ring tracks 30 move along ball hole 300b, movable ball 322 is close to the dragging track outer wall and is slided (Fig. 2 B is seen in phase diagram), and the dragging track outer wall will provide movable ball 322 to make the required centripetal force of circular movement.Movable ball 322 relative movement are up to the intersection of right wall that collides ball hole 300a and baffle plate 5, baffle plate 5 can slow down the bounce-back of movable ball 322, right wall of ball hole 300a and baffle plate 5 actings in conjunction provide the movable ball 322 tangential tangential components that quicken and the centripetal force of circular movement are provided, and make movable ball 322 realize quickening synchronously (Fig. 2 C is seen in phase diagram).This process will last till that fan quickens to finish, and enter uniform rotation state more stably.In this process, the right wall of ball hole 300a and baffle plate 5 offer movable ball 322 along a tangential component decrescence, up to the fan uniform rotation, this component is zero, at this moment, movable ball 322 falls into ball hole 300a fully, the normal force that ball hole 300a offers movable ball 322 makes movable ball 322 and the synchronous uniform circular motion of fan, when fan causes rotating speed to slow down because of problems such as power supplies or accelerates, movable ball 322 will little slip on ball hole 300a, produce mutual active force with left wall or right wall, provide that movable ball 322 is this to be slowed down or accelerate required tangential deceleration or quicken needed component, thereby under the situation of rotation speed of the fan shakiness, movable ball also can rotate synchronously with dragging track.The quality of movable ball 322 is superimposed upon fixedly ball 320 adjacents during because of stable state, realizes the off-centre of shake unit, produces vibration in the fan transhipment.Thereby realize ventilation fan heat radiation and vibrating alert function.
During starting fan, the position of rest of movable ball 322 may be in another ball hole 300, position view can be equally with reference to figure 2D, it is the same that driving mechanism is just changeing startup labor principle, movable ball 322 breaks away from the bottom of ball hole 300a, right wall and baffle plate 5 intersections at ball hole 300a are realized transporting (with Fig. 2 C) with the synchronous acceleration of fan, when driving mechanism reaches than the uniform rotation state, the movable ball 322 rollback hole of bead 300a bottom (with Fig. 2 D) that falls is realized the function of fan heat radiation and vibrating alert equally.
When Fig. 3 starts for the driving mechanism counter-rotating, position and the fixedly ball 320 symmetrical momentary status schematic representation of movable ball 322 in ball hole 300b, movable ball 322 breaks away from the bottom of ball hole 300b, right wall and baffle plate 5 intersections at ball hole 300b are realized rotating with the synchronous acceleration of fan, when fan reaches than the uniform rotation state, movable ball 322 falls bottom the 300b of the rollback hole of bead, because movable ball 322 is with fixedly ball 320 is symmetrical, the barycenter of whole shake unit drops in the rotating shaft, therefore fan can not produce vibration in rotation process, only has the fan heat sinking function when promptly reversing.
When Fig. 4 reverses for driving mechanism, movable ball 322 is in another ball hole 300a, position and the fixedly ball 320 adjacent momentary status schematic representation of movable ball 322 in ball hole 300a, movable ball 322 breaks away from the bottom of ball hole 300, relative movement slides into the intersection realization acceleration synchronously of right wall and the baffle plate 5 of ball hole 300a along track, at last, the rollback hole of bead 300a bottom that falls, same realization only has the fan heat sinking function when reversing.
When state of rest, movable ball 322 can also can because of factors such as gravity, also have probability on ring track in ball hole 300b in ball hole 300a.This depends on that fan is just to change or inverted status when the deceleration stall.No matter the position of the movable ball 322 of state of rest wherein, when driving mechanism 1 is just changeing, because of the interaction of power, movable ball 322 necessarily drops among the ball hole 300a when the fan smooth rotation, with fixedly ball 320 synchronous rotation axles 12 rotations, realize off-centre, produce vibration; During driving mechanism 1 counter-rotating, among the movable ball hole 300b that ball 322 drops on when stable state with fixedly ball 320 symmetries are mutually far away, whole shake unit barycenter drops in the rotating shaft 12, does not produce vibration.As seen, utilize this principle, whole micro fan need not special material, and overall structure is simple, can realize that controlled ventilation fan heat radiation or heat radiation add the vibrating alert function.
Provide a kind of micro fan that has vibrating alert and heat sinking function simultaneously at the utility model, on micro fan, install vibrating mechanism additional, according to mechanics principle when driving mechanism rotates and reverse, cause the difference of inner centroid position, thereby realize that controllably heat radiation and heat radiation add the function of vibration, when driving mechanism just changes, realize that the fan heat radiation adds the vibrating alert function, and when counter-rotating only realized the function of fan heat radiation.Simultaneously, between two ball holes, set up baffle plate, the collision between the ball is played certain effect that slows down by baffle plate, the degree of depth of ball hole is about the 1/4-1/3 of ball, and such aperture immersal structure is when fan running, and it is steady to constitute barycenter, make micro fan reduce noise, it is more stable to turn round.In addition, the utility model combines the vibration principle of vibrating motor with the structural design of micro fan, not only can reduce material and assembly cost, can also save system bulk, make it to meet the needs of miniaturization, light, slimming development, so that widely apply in the mobile phone or other consumption electronic products in future.
