Description
Technical field
The present invention relates to a kind of air inlet structures, more specifically to a kind of air inlet of adjustable air entraining pipe air inflow
Structure.
Background technology
At present, what is used on load-carrying vehicle is the air entraining pipe of the fixed piece that keeps off the rain, the piece that keeps off the rain with the horizontal certain angle,
The piece that keeps off the rain is high, low close to outer surface side close to air entraining pipe central side, i.e., low inside and high outside；The structure ensures will in the operation of rainy day vehicle
Rainwater is isolated in outside air entraining passage, and rainwater is avoided to enter air inlet system for vehicle, avoids the damage of engine.But it is kept off in the structure
The presence at rain piece inclination angle brings larger intake resistance to air inlet, reduces air inlet amount, is unfavorable for improving the combustion of vehicle
Oiliness economy.
The content of the invention
It is an object of the invention to be directed to the existing piece that keeps off the rain to cause intake resistance larger, no with the horizontal certain angle
The problems such as beneficial to the aviation fuel economy for improving vehicle, provide a kind of air inlet structure of adjustable air entraining pipe air inflow.
To achieve the above object, technical solution of the invention is：A kind of air inlet of adjustable air entraining pipe air inflow
Structure, including multiple pieces that keep off the rain, the piece both ends of keeping off the rain are connected respectively by axis pin with the air inlet inner wall of both sides, and are kept off
Rain on piece is provided with cantilever, and the cantilever between multiple pieces that keep off the rain is connected by connecting rod I.
The piece that keeps off the rain is reverse U shape structure, and corresponding piece both ends end of keeping off the rain is provided with U on the air inlet inner wall of both sides
The rainwater diversion slot of shape.
The connecting rod I is connected by connecting rod II with driving wheel, and II place plane phase of driving wheel, connecting rod I and connecting rod
Mutually parallel, driving wheel axle center is not on the extended line of connecting rod I.
Compared with prior art, the beneficial effects of the invention are as follows：
Piece both ends of keeping off the rain in the present invention are connected respectively by axis pin with the air inlet inner wall of both sides, and the piece that keeps off the rain can be revolved around axis pin
Turn certain angle so that keep off the rain piece tilt adjustable；On piece of keeping off the rain is provided with cantilever, and the cantilever between multiple pieces that keep off the rain passes through connecting rod
I is connected；The synchronous Inclination maneuver of multiple pieces that keep off the rain is realized by the connection of connecting rod I.Therefore, travelled in the rainy day, the piece that keeps off the rain is with showing
It is stateful to be consistent, it is ensured that rainwater is stopped in outside air entraining passage, ensures that engine is unaffected；It is travelled in the non-rainy day, it can
By the Inclination maneuver for the piece that keeps off the rain to level, intake resistance is reduced, increases air entraining pipe air inflow in the case where not changing other boundary conditions,
It may be such that engine combustion is more abundant, so as to reduce vehicle oil consumption, improve the fuel economy of vehicle.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure, keep off the rain piece 1, air inlet inner wall 2, connecting rod I 3, connecting rod II 4, driving wheel 5, axis pin 6, cantilever 7, rainwater diversion
Slot 8.
Specific embodiment
Below in conjunction with description of the drawings, the present invention is described in further detail with specific embodiment.
Referring to Fig. 1, a kind of air inlet structure of adjustable air entraining pipe air inflow is the plurality of to keep off the rain including multiple pieces 1 that keep off the rain
Piece 1 is arranged in air inlet；1 both ends of piece of keeping off the rain are connected respectively by axis pin 6 with the air inlet inner wall 2 of both sides, are made
The piece 1 that must keep off the rain can rotate by a certain angle around axis pin 6.And cantilever 7 is provided on the piece 1 that keeps off the rain, cantilever 7 is equipped with circular hole, multiple
The cantilever 7 to keep off the rain between piece 1 is connected by connecting rod I 3；The synchronous inclination angle tune of multiple pieces 1 that keep off the rain is realized by the connection of connecting rod I 3
It is whole.
Referring to Fig. 1, the piece 1 that keeps off the rain is reverse U shape structure, corresponding 1 both ends of piece of keeping off the rain on the air inlet inner wall 2 of both sides
End is provided with the rainwater diversion slot 8 of U-shaped, and rainwater diversion slot 8 is arranged below 1 both ends end of piece of keeping off the rain.Rainwater diversion slot 8
The rainwater at 1 both ends of piece of ensureing to keep off the rain can be flowed out by rainwater diversion slot 8, without flowing into air entraining pipe along air inlet inner wall 2；If not yet
Rain diversion trench 8, then keeping off the rain between piece 1 and air inlet inner wall 2 can be there are gap, and rainwater can be along flowing into air inlet inner wall 2
Air entraining passage.
Referring to Fig. 1, the connecting rod I 3 is connected by connecting rod II 4 with driving wheel 5, and driving wheel 5, connecting rod I 3 and connecting rod
II 4 place planes are mutually parallel, and 5 axle center of driving wheel is not on the extended line of connecting rod I 3.5 shape of connecting rod I 3, connecting rod II 4 and driving wheel
Into linkage, so as to by driving wheel 5（It is connected with servomotor）Rotation, connecting rod I 3 is transferred to by connecting rod II 4 so that
Connecting rod I 3 realizes the reciprocating motion of vertical direction and the Inclination maneuver of multiple pieces 1 that keep off the rain.When being connected on driving wheel 5 with connecting rod II 4
Point is rotated to top dead centre（Peak）When neighbouring, the piece 1 that keeps off the rain forms inclination maximum；When on driving wheel 5 with II 4 tie point of connecting rod revolve
Go to lower dead center（Minimum point）When neighbouring, the piece 1 that keeps off the rain is horizontal.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, it is impossible to assert
The specific implementation of the present invention is confined to these explanations.For those of ordinary skill in the art to which the present invention belongs, exist
On the premise of not departing from present inventive concept, several simple deduction or replace can also be made, said structure should be all considered as belonging to
Protection scope of the present invention.
