Description
Technical field
The present invention relates to the gas handling system of vehicle, more particularly to a kind of waterproof air inlet system of hybrid electric vehicle
System.
Background technology
Gas handling system is the important ingredient of automobile dynamic system, and its performance quality directly affects electromotor
Performance, or even directly determine that can electromotor normally run.
Used as the important spare part in automobile front chamber, its water inlet will result directly in electromotor and floods cylinder gas handling system
Quit work.Traditional gas handling system does not have water-proof function, and air inlet is easily intake, even through anti-
Water is designed, and is also only capable of meeting conventional rain-proof splash-proof requirement, can be intake easily in the case of waterflooding.As specially
Sharp document CN1740547A, it discloses a kind of air intake installation of waterproof vehicle, in arrangement air inlet
During mouth, air inlet is placed among the encirclement of front deck covering, prevents external rainwater from entering air inlet；Again
Such as patent documentation CN102654087A, a kind of air intake structure of waterproof air filter is it discloses, by air inlet
Mouth is avoided directly intaking windward, changes into side arrangement.
Both the above design structure is simple, while normal air inlet is not affected, it is therefore prevented that certain direction water
Attacking, can ensure that the filter element of air filter be not exposed to water in various sleety weathers or when rinsing vehicle.
But this air inlet is only capable of meeting conventional splash-proof requirement, if the water surface is too high to flood air inlet pipe, hydrops
Air inlet can be easily passed through to pour in down a chimney, normally using for gas handling system is affected.
Therefore, traditional gas handling system waterproofing design is not comprehensive enough, and classification of waterproof is not high enough, far from full
The waterproof requirement of gas handling system in the case of sufficient waterflooding.
The content of the invention
It is an object of the invention to provide a kind of waterproof air inlet system of hybrid electric vehicle, it disclosure satisfy that waterflooding
In the case of waterproof requirement, and simple structure easily realizes.
To achieve these goals, the present invention provides a kind of waterproof air inlet system of hybrid electric vehicle, including
Air filter assembly with air inlet pipe and escape pipe, and the air induction hose of the escape pipe is connected to, separately
Outward, the waterproof air inlet system also includes air inlet pipe mouth mold block and air inlet flow guide pipe, the air inlet pipe mouth mold
Block is connected on the inlet end of the air inlet flow guide pipe, and the outlet side of the air inlet flow guide pipe is connected to described
In air inlet pipe, and the air inlet pipe mouth mold block includes body, and is rotatably arranged in the body
To open or close the valve block of the body.
Using such scheme, in hybrid electric vehicle waterflooding, gas handling system can be directly closed, stop sending out
The work of motivation, is then switched to electric drive mode by hybrid electric vehicle, and vehicle can be continued to run with, suitable
Profit is by region of paddling.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
