Meanwhile under the pulling force effect of extension spring 8, the interior side direction of brake pad 7 to holding circle 4 is slided, brake pad 7 and outer barrel 1 does not contact, and keeps circle 4 to be rotated on outer barrel 1；In order that the present invention reaches preferable using effect, by inner cylinder 3 and fixed block Frictional force between 24 is arranged to higher value.

When the vehicle is running, external air flow flows through the inner side of outer barrel 1 and turbofan 2 is produced rotation, and turbofan 2 drives and turbofan The bevel gear wheel 5 of 2 connections rotates simultaneously, and because the frictional force between inner cylinder 3 and fixed block 24 is relatively large, gear engagement rubs It is relatively small to wipe the rotation friction sum of power, the rotation friction of bevel pinion 6 and holding circle 4, therefore inner cylinder 3 is not produced and turned Dynamic, the bevel gear wheel 5 being connected with inner cylinder 3 also remains stationary as, and now bevel pinion 7 produces under the engagement of bevel gear wheel 5 Own rotation simultaneously drives holding circle 4 to produce revolution motion.

Keep the revolution of circle 4 to make brake pad 7 produce centrifugation to slide, when car speed is relatively low, the velocity of rotation of turbofan 2 compared with It is low, therefore keep that the revolution speed of circle 4 is relatively low, and the centrifugal force acted on brake pad 7 is smaller, the centrifugation of brake pad 7 slide away from From smaller or do not slide；

With the increase of speed, increasing therewith by the air velocity of the inner side of outer barrel 1 makes the velocity of rotation of turbofan 2 constantly accelerate, The revolution speed of circle 4 is kept also to be continuously increased, the centrifugal force acted on brake pad 7 constantly increases and overcomes the pulling force of extension spring 8 Make brake pad 7 to 4 outer Slideslip of circle and gradually close with outer barrel 1 is kept, after brake pad 7 contacts with outer barrel 1, in centrifugal force In the presence of, the contact between brake pad 7 and outer barrel 1 gradually increases, therefore the frictional force between brake pad 7 and outer barrel 1 The revolution of holding circle 4 is obstructed, keep the revolution speed of circle 4 to be gradually reduced, but due to turbofan 2 drive be connected with turbofan 2 it is big The rotating speed of bevel gear 5 is constantly accelerated under airflow function or keeps constant trend, small after keeping the revolution speed of circle 4 to reduce The bevel gear wheel 5 that 7 pairs of bevel gear is connected with inner cylinder 3, which produces engagement, makes the bevel gear wheel 5 drive inner cylinder 3 to produce and turbofan 2 Reverse rotation, as the frictional force between brake pad 7 and outer barrel 1 constantly increases, the revolution rotating speed of bevel pinion 7 constantly drops Low, bevel gear wheel 5 drives the velocity of rotation of inner cylinder 3 to increase therewith, makes when the frictional force between brake pad 7 and outer barrel 1 increases to Keeping circle 4, the rotating speed of inner cylinder 3 is consistent with the rotating speed of turbofan 2 in opposite direction when can not rotate, and flabellum 9 rotates with inner cylinder 3 and by gas Stream blows to the lateral direction of outer barrel 1.

When needing to carry out in-car ventilation, handle 21 is stirred, external toothing 18 rotates simultaneously with ring gear 13, air outlet guard board 17 Engagement through second gear 19 and external toothing 18, which rotates, becomes larger the space between adjacent air outlet guard board 17, Inlet channel open, air-flow through exhaust vent 10 into the car, when air outlet guard board 17 turns to it is parallel with the direction of exhaust vent 10 when, Inlet channel is opened completely, reaches maximum intake；

With the further increase of speed, air velocity constantly increase and the rotation to fan of the inner side of outer barrel 1 form certain do Disturb, fan is blown into the air-flow of in-car and reduce, therefore when stirring handle 21, the rotation of ring gear 13 makes trunnion axis 14 through first The engagement of gear 15 and ring gear 13 rotates and drives the lateral direction of the phase inner cylinder 3 of rotating vane 16 to rotate, and outer barrel 1 is with turning Region between leaf 16 diminishes, and fraction is stopped by rotating vane 16 and is blown into in-car through fan, intake is increased again, reaches Preferable ventilation effect；When inlet channel fully opens, rotating vane 16 turn to it is closest or contacted with outer barrel 1 with outer barrel 1, Region between outer barrel 1 and rotating vane 16 reaches the minimum value of setting or closure, rotating vane 16 are in its fully unfolded position, air-flow completely Effectively it is blocked between outer barrel 1 and inner cylinder 3 by rotating vane 16, the air-flow being blocked is blown into in-car through fan, intake is reached pole Big value.

In order that the present invention reaches more preferable ventilation effect, outer barrel 1 can be lengthened and be added in one end where turbofan 2 Air filter screen is filled, the particulate matters such as the pollen in air can not only be filtered, after air-flow can also be made fully to cool in outer barrel 1 In-car is entered back into, in-car air is kept more comfortable state.

Clever structure of the present invention, it is simple to operate, drive turbofan to rotate using external air flow, and pass through centrifugal force controlled planet The motion of gear, and then realize and fan is automatically controlled under different speeds, complete the ventilation operation of vehicle；The present invention utilizes hand Handle synchronizes control to air outlet guard board and rotating vane to realize being blown into and stops control to air-flow, not only simplify to operate and walks Suddenly, it can also make air inlet effect more stable；Because external air flow need to be blown into by fan again after passing through fan, rather than directly it is blown into Vehicle interior, thus the present invention with directly windowing ventilation compare with wind make an uproar small, air-flow be blown into velocity-stabilization the characteristics of, while by It can ensure the unimpeded of air-flow in outer barrel and inner cylinder, it is controllable to the blocking effect of air-flow, therefore caused wind in driving conditions Resistance is smaller, will not increase excessive energy consumption and carry out offset resistance, the reduction for energy consumption serves good gain effect.

In addition, the present invention is controlled using centrifugal force to planetary gear to realize the control to fan running status, when During low vehicle speeds, fan does not rotate with turbofan, and the influence now travelled to vehicle by windage is smaller, therefore can open air-out Mouth realizes that the air-flow inside and outside vehicle exchanges by natural airflow during traveling, or the ventilation that opens a window as needed, can equally meet to make Use demand；When the vehicle runs at a high speed, fan rotates through planetary engagement with turbofan and rotating speed gradually increases, will more More air-flows is blown into in-car, and avoids the need for the worry of windowing ventilation；Meanwhile separating turbofan with inner cylinder is meeting fan Another gain effect to be worked under the conditions of specific speed is that fan will not be operated uninterruptedly, effectively reduces the abrasion of fan, carries High service life.
