Description
Technical field
This utility model relates to a kind of vehicle air conditioning outlet, belongs to technical field of automotive upholstery.
Background technology
Existing in view of user difference needs, in the hope of reaching the most comfortable effect, vehicle air conditioning outlet all has wind
To governor motion or air force governor motion.According to vehicle air conditioning outlet shape and the difference of regulative mode, substantially may be used
Spherical and grid type, wherein grid type vehicle air conditioning outlet is provided with scalable wind direction in generally comprising housing, housing
Vertical vane and horizontal blade, also have the air door mechanism for closing air outlet, such as Patent No. ZL200820032263.0
Chinese utility model patent " vehicle air conditioning outlet assembly " (Authorization Notice No.: CN201173556Y).
Having the vehicle air conditioning outlet of air door structure, the China referring to Patent No. ZL200520114144.6 is practical
New patent " a kind of vehicle air conditioning outlet " (Authorization Notice No.: CN2813347Y), the sealing lid (phase in this patent
When in air door) middle part is rotatably arranged at rotating cylinder (being equivalent to housing) in, seals lid perisporium and be provided with sealing ring, sealing Gai Youyi
Connecting rod drives and controls, and when sealing lid turns to level, then closes air outlet.But in actual application, this kind of structure
Close closure design poor sealing, in the case of completely closing also have a small amount of gas leakage, mainly sealing ring of tracing it to its cause
For easily worn part, long-time use is easily deformable, thus forms gap with rotating cylinder inwall, causes having gas out in the same old way.
To this end, the applicant discloses the air door structure of a kind of improvement, see the China of Patent No. 200920190514.2
(Authorization Notice No. is utility model patent " structure for improving sealing performance of throttle for automobile air conditioner air outlet "
CN201438030U), encapsulated in patent (sealing ring) it is convexly equipped with the jut that the inwall with housing contacts.Due to projection
The setting in portion, can effectively make up the gap produced because of encapsulated deformation, improve the airtight performance of air door.But work as air-conditioning
Air outlet close time or closing process in, air pressure can become suddenly big, when on-board air conditioner discharge pressure of fan one timing, encapsulated with
The gap of case inside wall is the least, and the blast that encapsulated edge is born is the biggest, and encapsulated by airflow influence, and vibration also can
The most obvious, (air-flow) turbulent flow causing encapsulated periphery is the most obvious, will produce offensive sharply uttering long and high-pitched sounds, shadow therewith
Ring and use impression.
For solving to utter long and high-pitched sounds problem, prior art has suffered a solution, sees Patent No. ZL201220361018.0
Chinese utility model patent " air throttle structure of air outlet of automobile air conditioner " (Authorization Notice No. is CN202734180), this patent
Improve in patent applicant, eliminate a circle stage portion of inner walls, utter long and high-pitched sounds it is thus regarded that solve.But this structure
Problem of uttering long and high-pitched sounds the most thoroughly solve, meanwhile, after life-time service sealing reduce.Therefore have much room for improvement.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of air door closing process for the above-mentioned state of the art
Middle energy reduces the air throttle structure of air outlet of automobile air conditioner uttered long and high-pitched sounds.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is: a kind of outlet air door of vehicle air conditioner knot
Structure, including housing and air door, aforesaid housing has cavity, and this cavity front end forms air outlet, and aforesaid air door can turn
Being arranged in cavity dynamicly and can open and close air outlet, the periphery of aforementioned air door is provided with a sealing ring, it is characterised in that described close
At least side indentation on rear side of on front side of the edge of seal and edge.
The assembling structure of sealing ring is preferably as follows: the outer face of described air door radially-inwardly forms cannelure, described sealing
The inner ring of circle is embedded in aforesaid cannelure.
For improving sealing, the inwall of described housing forming the stage portion of annular, described air door is closed down,
Described sealing ring is in sealing contact with stage portion.
Further, the side of described housing is provided with air door driving mechanism, and this air door driving mechanism includes
Thumb wheel, can be rotatably arranged in housing side；
Crank, is connected with the shaft of aforementioned air door；And
Connecting rod, one end is flexibly connected with aforesaid thumb wheel, and the other end is flexibly connected with aforesaid crank.
Further, the air outlet of described housing is provided with a panel, and this panel side has an installing hole, described thumb wheel portion
Divide and stretch out this installing hole.
Compared with prior art, the utility model has the advantage of: the zigzag of sealing ring outer end edges, it is possible to reduce week
Limit (air-flow) turbulent flow, thus reduce vibration, play the effect of uttering long and high-pitched sounds reducing wind door sealing structure.
