Description
Technical field
The invention belongs to the parts in air conditioning for automobiles, particularly a kind of air door mechanism.
Background technology
Automotive air conditioning device will realize the face of blowing, blows pin, defrosting isotype regulates, and air door is governor motion main at present, by motion and the stop of air door, guides the air flowing in air-conditioning box, realizes above-mentioned wind direction and regulate.
Come from high-end light truck to driving comfort sexual demand, the regulatory function of air-conditioning should meet the wish of user more.
Tradition truck air door structure is made up of air door body and sealing sponge, and air door bulk material is PP-ps40, and sponge material is polyethers foaming (PU) foam sponge, and sponge is fixed on air door body by the mode that glue is pasted.
There is following defect in existing air door structure:
Reliability is poor, and for a long time under the air-conditioning box environment of changes in temperature, sponge easily comes off.
Poor sealing, easily ventilative.When controller wire drawing stroke is less than normal or knob is not screwed into gear, the rotational angle of air door can less than normally cause air door thrust less than normal, and the decrement of sponge may be less than 50%, causes air door place to be leaked out.
Sponge material itself is ventilative, and due to Cost Problems, sealing sponge material multiselect polyethers foam sponge at present, this sponge material is open cell type, and cost is low, easily ventilative.
Sponge for a long time in air-conditioning box in wet environment, easily mouldy, produce peculiar smell, IAQ is driven in impact.
The controlling organization of pattern throttle linkage is comparatively complicated, needs to carry out coordinated signals to several air door, and control accuracy requires higher, easily causes leaking out.This structure is blown face, is blown pin, defroster door is that independently three connecting rods carry out coordinated signals, and this adds difficulty with regard to giving the design of rotating disk middle guide, and track slightly deviation will cause the problems such as air door clamping stagnation, thrust are little.
