When a rider rides, the fan 13 is driven by the wind power of the fan 13, so that the fan 13 rotates to drive the ring gear 14 to rotate, the driven large gear 22 rotates to drive the spring fixing shaft 21 to rotate, and the energy storage spring 20 contracts to store energy.
At the same time, the ring gear 14 rotates to rotate the driven pinion 40, thereby rotating the driven pinion shaft 43, which in turn rotates the spline housing 42, thereby rotating the drive bevel gear 44.
At the same time, the wind deflector 50 moves to the right under the influence of wind force to touch the contact switch 52, so that the contact switch 52 is triggered, thereby starting the electromagnet 47, so that the electromagnet 47 can electrically attract the magnetic shaft sleeve seat 45, so that the magnetic shaft sleeve seat 45 overcomes the elastic force of the shaft sleeve seat spring 46 to move rightwards, thereby moving the spline shaft housing 42 to the right, so that the left drive bevel gear 44 is engaged with the driven bevel gear 49, the right drive bevel gear 44 is disengaged from the driven bevel gear 49, so that the left side drive bevel gear 44 is rotated to rotate the driven bevel gear 49, and thus the upper side driven bevel gear shaft 48, thereby rotating the transmission belt 41, under the action of the friction force between the transmission belt 41 and the elastic film 33, the transmission belt 41 drives the elastic film 33 to rotate, so that the left side of the elastic film 33 moves downward and the right side of the elastic film 33 moves upward.
Due to the inward bulges on the front edge and the rear edge of the elastic film 33, the elastic film 33 always covers the cambered surface guide frame 34 during the movement.
Because the width of the inner side surface of the cambered surface guide frame 34 is equal to the width of the outer side surface of the cambered surface guide frame 34, the elastic film 33 coated on the cambered surface guide frame 34 can ensure that the width of the inner side elastic film 33 is equal to that of the outer side elastic film 33 in the movement process, so that the elastic film 33 can always keep the smooth and tight surface state, and the sight of a driver is not influenced in the use process.
When the driver parks and waits for the traffic lights, because the vehicle stop motion, make the wind-force that deep bead 50 received reduce, thereby make deep bead 50 move to keeping away from contact switch 52 to left under deep bead spring 51's elastic force effect, and then make contact switch 52 stop triggering, make electromagnet 47 close, electromagnet 47 loses the electricity promptly, then magnetism axle sleeve seat 45 loses the appeal of electromagnet 47, make magnetism axle sleeve seat 45 move left under the elastic force effect of axle sleeve seat spring 46, thereby make right side magnetism axle sleeve seat 45 and driven bevel gear 49 meshing, left side magnetism axle sleeve seat 45 and driven bevel gear 49 break away from the meshing.
Meanwhile, because the fan 13 is not driven by wind, the energy storage spring 20 rotates reversely under the action of self elasticity, the fan 13 rotates reversely, the driving bevel gear 44 is driven to rotate reversely, the driving bevel gear 44 on the right side drives the driven bevel gear 49 to rotate in the same direction as before, the elastic film 33 keeps the rotating direction, rainwater or dust on the elastic film 33 can be cleaned when the driver stops at traffic lights such as a temporary stop, the driver can see the front clearly when driving again, and the driving safety is guaranteed.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
