Abstract
The utility model discloses a kind of air outlet for preventing from uttering long and high-pitched sounds, it is characterised in that：Including air outlet housing, toggle, connecting rod and one group of sealing blade；The two ends of the sealing blade are connected with air outlet housing and sealing blade respectively, and the toggle is located on wherein one sealing blade, and it is raised that the sealing blade is provided with one group of flow-disturbing.This utility model destroys the vortex structure of quasi-ordering by distinctive flow-disturbing bulge-structure, reduces air resonance, so as to solve to utter long and high-pitched sounds.
Description
Technical field
This utility model is related to automobile interior functional part field, particularly a kind of air outlet for preventing from uttering long and high-pitched sounds.
Background technology
Passenger car noise, vibration and sound vibration roughness（Noise, Vibration, Harshness, NVH）The direct shadow of performance
Ring and arrive riding comfort, it is a kind of common NVH problems that air-conditioner air outlet is uttered long and high-pitched sounds, passenger can be caused uncomfortable and fatigue, increasingly
Many main engine plants and supplier start to be concerned about and try to solve the problem.
Similar air outlet enclosure interior includes the structures such as toggle, sealing blade, when sealing blade will be closed, can produce
Raw phenomenon of uttering long and high-pitched sounds.If simultaneously closing off other air outlets, single air outlet pressure drop increases, and utters long and high-pitched sounds and becomes apparent from.
Utility model content
Goal of the invention：In order to overcome the deficiencies in the prior art, this utility model offer is a kind of to prevent that uttered long and high-pitched sounds to go out
Air port.
Technical scheme：For solving above-mentioned technical problem, a kind of air outlet for preventing from uttering long and high-pitched sounds that this utility model is provided, its are special
Levy and be：Including air outlet housing, toggle, connecting rod and one group of sealing blade；Described sealing blade two ends respectively with air-out
Mouth housing is connected with sealing blade, and the toggle is located on wherein one sealing blade, and the sealing blade is provided with one group of flow-disturbing
Raised.
Further, the flow-disturbing projection is isodistantly spaced and is uniformly distributed.
Further, it is in half cone-shaped that the flow-disturbing is raised, parallel with sealing blade face.
Further, the quantity of the sealing blade is 5.
Further, the raised quantity of the flow-disturbing is 3 ~ 10.
Further, the envelope blade is provided with union joint, realizes the connection with connecting rod.
Beneficial effect：This utility model has advantages below in terms of existing technologies：
This utility model destroys the vortex structure of quasi-ordering by distinctive flow-disturbing bulge-structure, reduces air resonance, so as to
Solution is uttered long and high-pitched sounds.
Description of the drawings
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model sealing blade construction schematic diagram.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described.
As illustrated in fig. 1 and 2, a kind of air outlet for preventing from uttering long and high-pitched sounds that this utility model is provided, including air outlet housing 1, dials
Button 2, connecting rod 3 and one group of sealing blade 4；Described sealing blade 4 two ends respectively with air outlet housing 1 and seal 4 phase of blade
Even, the toggle 2 is located on wherein one sealing blade 4, and the sealing blade 4 is provided with one group of flow-disturbing projection 5.The flow-disturbing is convex
Play 5 to be isodistantly spaced and be uniformly distributed.It is in half cone-shaped that the flow-disturbing is raised, parallel with 5 face of sealing blade, is located at 5 end of sealing blade
Portion.The quantity of the sealing blade 5 is 5.The quantity of the flow-disturbing projection 5 is 3 ~ 10.4 company of being provided with of the sealing blade
Joint 6, realizes the connection with connecting rod 3.
The above is only preferred implementation of the present utility model, it should be pointed out that：Common skill for the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improvement and
Retouching also should be regarded as protection domain of the present utility model.
