Description
Technical field
The present invention relates to a kind of air inlet pipe, especially relate to a kind of air feeder structure that improves fordability.
Background technology
Vehicle has become a kind of general vehicles, and along with the development of auto industry, it is superior that vehicle usesPerformance also more and more receives designer and user's concern. Wherein gas handling system is the key of engine workOne of link, it comprises air filter and admission line, air enters air filter through admission line, filtersThe various dust grains of sand in atmosphere, then enter engine. But at sleety weather, especially there is heavy rain or largeWhen wind and snow, vehicle is immersed in water, and water flows into air filter by admission line, in the time that vehicle starts again,Part water enters engine can affect the vehicle life-span.
Summary of the invention
Object of the present invention is exactly to provide a kind of simple in structure, effect in order to overcome the defect that above-mentioned prior art existsThe air feeder structure of the improved fordability that fruit is good.
Object of the present invention can be achieved through the following technical solutions: a kind of air inlet duct ligation that improves fordabilityStructure, described air inlet pipe connects air filter, it is characterized in that, and described air inlet pipe is provided with a mouth of pipe upwardAir inlet pipe, make the air inlet end of air inlet pipe be divided into main air inlet pipe and an air inlet pipe, described main air inlet pipe andIn air inlet pipe, be equipped with electrically-controlled valve, when water enters after main air inlet pipe, the electrically-controlled valve in main air inlet pipe is closed, atmosphere fromProp up air inlet pipe and enter air filter, work on, in the time that the air inlet pipe mouth of pipe is propped up in water level arrival, in an air inlet pipeElectrically-controlled valve is closed, and anti-sealing enters air inlet pipe.
The mouth of pipe of described main air inlet pipe is provided with sensor a, and electrically-controlled valve a is set in main air inlet pipe, an air inlet pipeThe mouth of pipe is provided with in sensor b, an air inlet pipe and electrically-controlled valve b is set, sensor a, electrically-controlled valve a, sensor b and electricityControl valve b all connects a controller, and the water level information that sensor a and sensor b detect sends controller to, logicalCross the opening and closing of controller control electrically-controlled valve a and electrically-controlled valve b.
Described sensor a is arranged on the lowest part of the main air inlet pipe mouth of pipe, and described sensor b is arranged on Zhi JinqiThe lowest part of the pipe mouth of pipe.
In described main air inlet pipe, be provided with the installation draw-in groove a that electrically-controlled valve a is tightly connected, in a described air inlet pipe, establishThere is the installation draw-in groove b being tightly connected with electrically-controlled valve b.
A described air inlet pipe is the branch road separating from air inlet pipe, and an air inlet pipe is arranged on air inlet pipe top, its pipeUpwards, the length of an air inlet pipe is 10～50mm to mouth.
Compared with prior art, the present invention arranges an air inlet pipeline, this air inlet pipeline at the port of export of air inlet pipeUpwards extend, upward, in the time that excessive water enters main air inlet pipeline, electrically-controlled valve a closes the mouth of pipe, makes main air inlet pipeRoad is closed, and anti-sealing enters engine, because an air inlet pipeline designs upward, is equivalent to warning line to carry simultaneouslyGao Liao, atmosphere still can enter from an air inlet pipeline, and vehicle is normally moved, when water level arrives the pipe that props up air inlet pipelineWhen mouth, the electrically-controlled valve in an air inlet pipeline is closed and is sealed, and places water and enters air filter, effectively improves vapour
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As shown in Figure 1, a kind of air feeder structure that improves fordability, described air inlet pipe connects air-filteringDevice, described air inlet pipe is provided with a mouth of pipe air inlet pipe upward, makes the air inlet end of air inlet pipe be divided into main air inletPipe 1 and an air inlet pipe 2, make the air inlet end of air inlet pipe be " Y " type. Prop up air inlet pipe for to separate from air inlet pipeBranch road, air inlet pipe is arranged on air inlet pipe top, upwards, the length of an air inlet pipe is 10～50mm to its mouth of pipe,Be equivalent to the warning line of vehicle to improve 10～50mm.
The mouth of pipe of described main air inlet pipe 1 is provided with sensor a11, electrically-controlled valve a12 is set, Zhi Jin in main air inlet pipeThe mouth of pipe of tracheae is provided with in sensor b21, an air inlet pipe electrically-controlled valve b22 is set, and in main air inlet pipe, is provided with electrically-controlled valveThe installation draw-in groove a that a is tightly connected, is provided with the installation draw-in groove being tightly connected with electrically-controlled valve b in a described air inlet pipeB, sensor a11, electrically-controlled valve a12, sensor b21 and electrically-controlled valve b22 are all connected same controller, sensorThe water level information that a11 and sensor b21 detect sends controller to, by controller control electrically-controlled valve a12 andThe opening and closing of electrically-controlled valve b22.
Sensor a11 is arranged on the lowest part of main air inlet pipe 1 mouth of pipe, and described sensor b21 is arranged on Zhi JinqiManage the lowest part of 2 mouths of pipe, when water enters after main air inlet pipe 1, sensor a11 detects water level and has exceeded warning waterPosition, just passes to controller by this information, and controller control electrically-controlled valve a12 closes, and now, atmosphere is from an air inlet pipeEnter air filter, work on, meet the Vehicle Driving Cycle under low speed, when water level arrives air inlet pipe 2 mouth of pipeTime, the electrically-controlled valve b22 in air inlet pipe closes, and anti-sealing enters air inlet pipe, effectively improves automobile engineService life.
