Background technology
When hydrops chin-deep on rainy day road, automobile is placed on road surface, hydrops can enter cylinder via the air inlet pipe of automobile, Incoercibility due to water, piston movement stroke will shorten thus causing engine link bending or fracture, fracture connecting rod can be caused to fly out and puncture cylinder body, cause the damage of automobile under extreme condition, in prior art, there is not yet the device for preventing automotive air intake water inlet tube of a kind of simple in construction.
Summary of the invention
It is an object of the invention to provide the automotive air intake pipe waterproof device of a kind of simple in construction.
For realizing object above, the technical solution used in the present invention is: a kind of automotive air intake pipe waterproof device, including connecting rod, one end of connecting rod connects ball float, the other end connects baffle plate, the plate face of connecting rod and baffle plate is that angle formula is arranged, the bottom margin of the mouth of pipe of baffle plate and air inlet pipe is hinged, is sagging shape during ball float free state, and the mouth of pipe of air inlet pipe is in open state；When ball float is bubbled through the water column upper by buoyancy, baffle plate is resisted against on the end face of the mouth of pipe.
Compared with prior art, there is techniques below effect in the present invention: vehicle travels without hydrops road surface, and whole device is hung on the bottom of the mouth of pipe because of action of gravity, and baffle plate will not block the mouth of pipe of air inlet pipe；When surface gathered water is deeper, ball float floats on the surface, and baffle plate together rotates and is resisted against with ball float and connecting rod on the mouth of pipe end face of air inlet pipe and air inlet pipe blocked, and effectively prevents hydrops from entering air inlet pipe, and structure is relatively simple.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is present invention structural representation when being placed on hydrops road surface.
Detailed description of the invention
Below in conjunction with Fig. 1 to Fig. 2, the present invention is described in further detail.
A kind of automotive air intake pipe waterproof device, including connecting rod 10, one end of connecting rod 10 connects ball float 20, the other end connects baffle plate 30, the plate face of connecting rod 10 and baffle plate 30 is that angle formula is arranged, the bottom margin of the mouth of pipe 41 of baffle plate 30 and air inlet pipe 40 is hinged, being sagging shape during ball float 20 free state, the mouth of pipe 41 of air inlet pipe 40 is in open state；When ball float 20 is bubbled through the water column upper by buoyancy, baffle plate 30 is resisted against on the end face of the mouth of pipe 41.In conjunction with Fig. 1, when road surface is without hydrops, whole waterproof device because being hung on the bottom of the mouth of pipe 41 of air inlet pipe 40 by action of gravity, and the mouth of pipe 41 is in open state, and air inlet pipe 41 can normally use；In conjunction with Fig. 2, when there is hydrops on road surface, ball float 20 is because of by buoyancy, ball float 20 turns to and swims on the water surface, the rotation rotating drive baffle plate 30 of ball float 20, until baffle plate 30 is resisted against the closing realizing line up 41 on the end face of the mouth of pipe 41, effectively prevents hydrops from entering in air inlet pipe 40.After hydrops disappears, ball float 20 rotates around described hinged place, falls to free shape, drives baffle plate 30 to rotate simultaneously, baffle plate 30 and the mouth of pipe 41 depart from, and the mouth of pipe 41 is in open state again, and air inlet pipe 40 just can normally use, the structure of whole device is relatively simple, and manufacturing cost is relatively low.
Preferred version: the edge contour of described baffle plate 30 is consistent with the edge contour of the mouth of pipe 41, coaming plate 31 is arranged to the mouth of pipe 41 place side-stand type in the edge of baffle plate 30, on coaming plate 31 and air inlet pipe 40, the outer peripheral face socket near the mouth of pipe 41 coordinates, and the mouth of pipe 41 is wrapped by coaming plate 31, makes water-inlet-proof better effects if.
Further, the direction of the jointed shaft 50 of described hinged place is arranged along vehicle-body width direction, the pipe shaft of air inlet pipe 40 is arranged block 60 near jointed shaft 50 place, when connecting rod 10 is in plumb position, block 60 and baffle plate 30 are positioned at the both sides of connecting rod 10, the setting of block 60 can stop that ball float 20 is floating to the direction away from the mouth of pipe 41, it is ensured that ball float 20 is when floating, and baffle plate 30 can be resisted against on the mouth of pipe 41.
The angular range in the plate face of described connecting rod 10 and baffle plate 30 is 90 °-130 °, and the angle in the plate face of connecting rod 10 and baffle plate 30 can be determined according to the angle of inclination of the end face of the mouth of pipe 41, it is ensured that when ball float 20 swims on the water surface, baffle plate 60 can recline with the mouth of pipe 41.
Seal between described baffle plate 30, coaming plate 31 and the mouth of pipe 41 of air inlet pipe 40 and coordinate, it is ensured that hydrops will not enter in air inlet pipe 40 when coordinating.
The hollow ball that described ball float 20 is made up of plastic material, makes ball float 20 can float on the water surface.
Described connecting rod 10 is connected with the edge of baffle plate 30, the angle in the plate face of connecting rod 10 and baffle plate 30 is 90 °, jointed shaft 50 is positioned at the external corners place of described angle, because the end face of the mouth of pipe 41 of general air inlet pipe 40 is all in vertical, so the angle by the plate face of connecting rod 10 and baffle plate 30 is designed as 90 °, when ball float 20 swims on the water surface, connecting rod 10 is horizontal direction, and the plate face of baffle plate 30 is vertical, just ensure that the end face of baffle plate 30 and the mouth of pipe 41 reclines and reaches water-inlet-proof effect.
Between described block 60 and connecting rod 10, magnet attraction unit is set, therebetween the buoyancy that magnetic picture is subject to less than ball float 20 for the moment of jointed shaft 50 on the water surface is relative to the moment of jointed shaft 50, when road surface is without hydrops, because magneticaction is pulled together between block 60 and connecting rod 10, when vehicle travels, can prevent whole waterproof device from swinging and produce noise or break other parts；When there is hydrops on road surface, after the magnetic force between buoyancy overcoming block 60 and the connecting rod 10 of ball float 20, ball float 20 swims on the water surface.
In order to make water-inlet-proof better effects if, the plate face towards the mouth of pipe 41 in baffle plate 30 is cambered surface 32, cambered surface 32 is protruding to the outside of baffle plate 30, and the edge of cambered surface 32 and the internal diameter of the mouth of pipe 41 coincide, and the projection at cambered surface 32 place of baffle plate 30 side is equivalent to stopper and is clogged by the mouth of pipe 41.
