Abstract
The utility model relates to the field of an automobile air-conditioning box, and particularly relates to an automobile air-conditioning air door. A secondarily injected automobile air-conditioning air door with double sealing surfaces comprises a door plate and a door shaft; the door shaft is arranged at the axis of the door plate; a motor connector is arranged at one end of the door shaft; a shell connector is arranged at the other end of the door shaft; a circle of elastic body is coated outside the door plate; the shell connector is formed by two circles of inner and outer rings; and a gap between the two circles of inner and outer rings is matched with a shell connecting sleeve. Two sealing surfaces are formed by the two circles of inner and outer rings; and a circle of elastic body is coated outside the outer ring of the door plate, so that the sealing effect is improved; the leakage rate of the air door is reduced on the premise of not changing the whole structure of the air conditioner, and not generating a large effect on the air inlet amount of the air-conditioning box; the structure of the air-conditioning box is simplified; meanwhile, the secondarily injected automobile air-conditioning air door is simple in installation process on a production line of an air-conditioning box assembly, and flexible to operate, and can be used for saving lubricating oil for sealing, and reducing the production cost of the air-conditioning box.
Description
Technical field
The utility model relates to the automobile air conditioning box field, relates in particular to a kind of automobile air-conditioning throttle.
Background technology
Development along with science and technology, people are also more and more higher to the requirement of air conditioning for automobiles, not only require air-conditioning that good cooling and warming performance is arranged, and require the aircondition volume little, can adjust according to client's needs wind-warm syndrome humidity, air-out volume and leaving air temp.Sealing requirements to air door is also stricter.Internal-external cycle throttle can be from all-fresh air to full return air, guarantee that appropriate new wind enters, thereby guarantee that car is interior with fresh air, the leakage rate of internal-external cycle throttle requires lower than 2L/s, the leakage rate of blowing top blast pin air door requires lower than 1L/s, and the leakage rate of defroster door requires lower than 0.5L/s.Good sealing performance of throttle enough improves the comfortableness of air-conditioning.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of quadric injection mould double-sealing face automobile air-conditioning throttle, forms two sealing surfaces by inside and outside two circle circular ring structures, has improved sealing effectiveness, has also simplified the structure of air-conditioning box simultaneously.
The utility model is achieved in that a kind of quadric injection mould double-sealing face automobile air-conditioning throttle, comprise door-plate and door-hinge, described door-hinge is arranged on the axle center of door-plate, one end of door-hinge is equipped with motor connector, the other end of door-hinge is equipped with the housing connector, described door-plate is surrounded by a circle elastomer outward, and described housing connector is made of inside and outside two circle annulus, matches with the housing female connector in the gap between described inside and outside two circle annulus.
Described elastomer is the bilateral elastomer of V-arrangement.
The angle angle [alpha] of described V-arrangement is 40 ° ~ 60 °.
Also be provided with reinforcement on described door-plate.
The end that the utility model quadric injection mould double-sealing face automobile air-conditioning throttle is connected with the housing female connector forms two sealing surfaces by inside and outside two circle circular ring structures, and the outer ring of door-plate is surrounded by a circle elastomer, has improved sealing effectiveness; In the overall structure that does not change air-conditioning, simultaneously the intake volume of air-conditioning box do not produced under the prerequisite of considerable influence again, reduce the leakage rate of air door, simplified the structure of air-conditioning box; Installation process is simple on the production line of air-conditioning box assembly simultaneously, flexible operation, and saved the lubricating oil that is used for sealing, reduced the production cost of air-conditioning box.
