End is connect with rope 121.When flywheel body 101 rotating speed increase when, weight slide block 117 can due to self gravitation effect and by
The external force effect upward sliding arrived.121 one end of rope is connect with weight slide block 117, and the other end connects across sliding part 119 and second
It connects end 111 to be fixedly connected, 111 one end of second connection end is fixedly connected with flabellum 103, the other end and the inner wall of installation passage 125
It is slidably connected, the first connecting pin 109 is flexibly connected with installed part ontology 123.When 117 upward sliding of weight slide block, rope 121
By pulley action drive one end that second connection end 111 and 125 inner wall of installation passage are slidably connected in installation passage 125 to
Right slip.At this point, the other end due to second connection end 111 with flabellum 103 is to be fixedly connected, work as second connection end 111
It turns right during slip with flabellum 103, the first connecting pin 109 can be gradually distance from due to the gravity that receives and pulling force effect
Flywheel body 101 also gradually increases so as to fulfill the first connecting pin 109 and the angle of the tangent line of flywheel body 101, and then can be with
Improve flabellum 103 and cooling effect area, so as to improve radiating efficiency.Meanwhile by rotating speed come adjust heat dissipation effect this
One design is also effectively improved the flexibility of flywheel fan 100, has saved resource, avoids waste, and need in small air quantity
The generated noise that runs at high speed is reduced when asking, ensure that the property requirements of 100 low noise of flywheel fan.
As a preferred option, mounting portion 105 also has the second elastic component 115, and 115 one end of the second elastic component connects with second
111 connection of end is connect, the other end is connect with installed part ontology 123.Second elastic component, 115 one side can be to second connection end 111
A cushioning effect to be played, on the other hand a draw can be provided so that the movement of second connection end 111 is more steady,
So as to ensure the even running of flabellum 103.
In the present embodiment, referring to Fig. 4, the first elastic component 113 and the second elastic component 115 are spring.Spring is one
Kind utilizes elasticity come the machine components of work.Part deforms upon under external force made of elastic material, removes external force
It restores to the original state again afterwards.Also make " spring ".Generally it is made of spring steel.The type complexity of spring is various, by shape point, mainly there is spiral shell
Revolve spring, scroll spring, flat spring, heterotypic spring etc..In the present embodiment, the type of spring does not limit, and user can be with
It is selected according to self-demand.Certainly, in the other embodiment of the utility model, the type of elastic component is not limited in bullet
Spring, it is also an option that for shrapnel etc., the utility model does not limit.
In the present embodiment, referring to Fig. 4, sliding part 119 is pulley.Pulley is that a periphery has slot, can be around shaft rotation
Dynamic steamboat.By flexible cable (rope, adhesive tape, cable wire, chain etc.) institute that can be around the fluted disk of central axis and across disk
Composition can be called pulley around the simple and mechanical of center axis rotation.Certainly, it is sliding in the other embodiment of the utility model
The type of moving part 119 can also be selected according to demand, and the utility model does not limit.
In the present embodiment, referring to Fig. 1, the number of flabellum 103 is 6.Certainly, the utility model other
In embodiment, the number of flabellum 103 can also be selected according to demand, such as can with selected as 5,7,8 and more
More etc., the utility model does not limit.
The present embodiment additionally provides a kind of engine and includes engine body and the flywheel being set in engine body
