Description
[technical field]
The utility model relates to a kind of air conditioning for automobiles rotary air valve sealing arrangement.
[background technology]
Along with the develop rapidly of modern automobile a/c system, it is perfect that automotive air-conditioning system is tending towards more, wherein increased some functions, as heat, defrosting etc., this has just determined the variation of air supply pattern.Therefore, in air conditioning for automobiles, need enter in the compartment by a plurality of air discharge ports through the air of overregulate, thereby, its air-out pattern is divided into following five kinds basically, shown in Fig. 1-5, is respectively: defrosting mode, and the pin pattern is blown in defrosting, blow the pin pattern, blow pin and blow surface model, blow surface model.Be directed to this, at present air conditioning for automobiles also be provided with the defrosting air port mostly, blow the face air port, blow the pin air port, back dispatch wind air port etc.In this case, the air discharge port pattern will increase greatly by the complexity that mechanical device is provided with, and has also increased the size of A/C air-supply arrangement.Therefore, be necessary the throttle setting of air-conditioning air-out pattern is studied, to reach the comfort feature and the practicality of installing and using.
In order to simplify throttle setting, many rotary air valves that all adopt disclose a kind of A/C that adopts rotary air valve as Chinese patent CN1153112A in the prior art.Its compact conformation uses simply, the convenient switching that realizes multiple air-out pattern.But there is the shortcoming of poor sealing in rotary air valve, and this in use causes great inconvenience will for the user, needs the sealing problem of rotary air valve is studied for this reason.Provided some solutions among another part Chinese patent CN1103702C, it is by installing diaphragm additional, and to keep at least one end be free end, by gas pressure diaphragm is abutted against on the inwall of rotary air valve housing, thereby has improved sealing property effectively.
[utility model content]
Technical problem to be solved in the utility model is: design a simple and reliable rotary air valve sealing arrangement and regulate the air-out pattern of air conditioning for automobiles, and improve the leak tightness of rotary air valve as far as possible.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
In this air-out pattern throttle setting, mainly comprise three parts: the rotary air valve of first for rotating around self rotating shaft; Second portion is to have flexible diaphragm; Third part is the support sponge between the outer circle wall of diaphragm and rotary air valve.
Rotary air valve is half-cylindrical framed structure, circle wall of outside formation, rotary air valve can have been cut platform along a certain angle in the one end rotating shaft around self rotating shaft rotation, be used for and carry out connecting rod being rigidly connected, the rotary air valve framework is the support component that supports diaphragm.A plurality of openings are arranged on the periphery of rotary air valve, whole rotary air valve places air conditioning box body to be right after in the revolution space at air outlet place, when the air outlet on the housing is communicated with the vent window of rotary air valve, be opened, and with vent window beyond zone when contacting, air outlet is then sealed up by diaphragm.The gap that has 5mm between the outer circle wall of diaphragm and rotary air valve.
In the gap that exists between the outer circle wall of diaphragm and rotary air valve, there is the sponge of support to fill.The support sponge is an elastic support member, and being used to keep described diaphragm is tensioning state, and is the arcwall face coaxial with the rotary air valve outer circle wall, can play a leak free effect like this.
Air extractor vent on the diaphragm overlaps with corresponding opening on the rotary air valve, to form vent window, is opened when the ventilation inlet in air channel is communicated with the vent window of rotary air valve, and other is then sealed up by diaphragm with the air channel that exterior domain contacts with vent window.On the edge of one end of diaphragm outer circle wall one end at rotary air valve fixed by snap, the part of the other end is passed from the chute of rotary air valve outer circle wall one end margin, outwardly-bent again 180 degree are fixed on the edge of chute side, another part inserts in the chute, forms the elastic bending fixed end.The buckle here can have multiple, uses these two kinds of mushroom-shaped buckle and hook-type buckles in two kinds of this utility model different embodiments.
When rotary air valve rotates, diaphragm can be along with the actual conditions expansion or the contraction automatically of peripheral casing, when the air-out pattern is changed, peripheral casing can be squeezed in some part of the diaphragm of being expanded by blast before the mode converting, then the Elastic Fixed Ends of diaphragm has corresponding variation, the film strip that passes chute can be to the inner slide of rotary air valve framework under elastomeric effect, and the film strip that snaps in draw-in groove can slide in draw-in groove with moving of whole diaphragm; Blast can make some part of the diaphragm that is pushed by peripheral casing before mode converting expand again simultaneously, then the Elastic Fixed Ends of diaphragm also can be made corresponding variation at this moment, the film strip that passes chute can slide in the outside to the rotary air valve framework under the pulling of diaphragm main body, and the film strip that snaps in draw-in groove can move outside draw-in groove with whole diaphragm.Therefore, diaphragm all the time can with peripheral casing each air outlet closed contact particularly, when rotary air valve expands with heat and contract with cold owing to temperature traverse, film spare is expansion or contraction automatically, make diaphragm be close to peripheral casing all the time, and do not produce fold, realized sealing function.
The utility model has the advantages that, make diaphragm have scalability, improved the sealing property of rotary air valve by the Elastic Fixed Ends of using diaphragm.Through the actual proof of using, the utility model is simple and compact for structure, and is easy to use and reliable, and sealing property is superior.
