Abstract
The utility model discloses a bidirectional turnup edge encapsulation air door structure for a vehicle air-conditioning box. The bidirectional turnup edge encapsulation air door structure comprises an air door body, wherein the air door body is provided with a rotary shaft chamber; bidirectional turnup edge encapsulation is formed on the air door body; the bidirectional turnup edge encapsulation has an angle relative to the plane where the air door body is located; and the angle of the bidirectional turnup edge encapsulation relative to the plane where the air door body is located is an obtuse angle at the side facing a sealing structure. According to the bidirectional turnup edge encapsulation air door structure, after the planar encapsulation on the existing air door structure is changed into bidirectional turnup edge encapsulation, when the air door body turns to a limit position, owing to the existence of the angle, the encapsulation on the air door body is compressed tightly and deforms appropriately without encapsulation curl and swell phenomena, however the sealing performance is good, so that the balance and the effective distribution of the air quantity in the vehicle air-conditioning box are ensured.
Description
Technical field
The utility model relates to the motorcar air conditioner technical field, relates in particular to a kind of encapsulate air door structure that is used for the air conditioning for automobiles case.
Background technology
The air conditioning for automobiles case need lean on the routing motion of various air doors to realize functions such as air circulation, air quantity distribution and adjustment.According to the requirement of its function, the air door of air conditioning for automobiles case generally can be divided into fresh wind/cycle throttle, temperature blender door, distribution air door.The air quantity distribution function of air conditioning for automobiles case plays the effect of balance air quantity, is the key factor that air obtains good comfort in the car.Air-conditioning box mainly comprises the distribution of three air quantity, is respectively defrosting, blows face, blows pin.Therefore, the distribution air door can be divided into defroster door again, blows the face air door, blows three kinds of pin air doors.
No matter any air door when two extreme positions work of opening and closing, all requires the maintenance excellent sealing performance.Like this, could guarantee the balance of air quantity and effectively distribution.In the past, the method for pasting sealing strip is adopted in the sealing of air door mostly, complex process, and cost is high, and the air door volume is big, hinders gas flow.Now, most air conditioning for automobiles casees adopt the encapsulate air door of quadric injection mould moulding, utilize to have certain flexible encapsulate on the air door structure and partly realize sealing.But in practical application, mechanical movements such as the opening and closing of air door are all realized by the motion of air-conditioning box.During design movement mechanism, in order to let air door close tightlyer at extreme position, better tightness all can let the rotational angle interference (the promptly rotation several years) of air door more.
Like Fig. 1, shown in Figure 2, existing plane encapsulate air door structure mainly comprises the air door body 1 with rotation axocoel 11, on air door body 1, forms plane encapsulate 12 through quadric injection mould.When air door body 1 turned to extreme closed position, the plane encapsulate 12 of both sides compressed with the hermetically-sealed construction 2 of air-conditioning box housing respectively and realizes sealing.Air door body 1 is after having rotated certain interference angle, and plane encapsulate 12 all can have the distortion of certain size usually.
Existing this plane encapsulate air door structure because plane encapsulate 12 is simple in structure, does not have deformation space after fastening; The edge of plane encapsulate 12 receives the support of air door body 1 weak; After stressed, it is serious but do not have deformation space that plane encapsulate 12 receives the crimp of hermetically-sealed construction 2, deforms easily excessively, encapsulate curls and the protuberance phenomenon; Cause the sealing of whole wind door to reduce, thereby had influence on air balance and effectively distribution in the air conditioning for automobiles case.
Therefore, those skilled in the art is devoted to develop a kind of encapsulate air door structure of simple in structure, good seal.
The utility model content
Because the above-mentioned defective of prior art, the utility model technical problem to be solved provides a kind of simple in structure, two-way flange encapsulate air door structure that is used for the air conditioning for automobiles case that sealing is good.
For realizing above-mentioned purpose, the utility model provides a kind of two-way flange encapsulate air door structure that is used for the air conditioning for automobiles case, comprises the air door body with rotation axocoel; Be formed with two-way flange encapsulate on the said air door body; The plane at the said relatively air door body of said two-way flange encapsulate place has an angle, and the said angle between the plane at the said relatively air door body of said two-way flange encapsulate place is being the obtuse angle in the face of hermetically-sealed construction one side.
Preferably, said two-way flange encapsulate is the thermoplastic rubber material.
Preferably, said air door body is the PP-T40 material.
The beneficial effect of the utility model is:
After the utility model will have plane encapsulate on the air door structure now and change two-way flange encapsulate into; When the air door body turns to extreme position; Because the existence of this angle, distortion did not suitably have encapsulate to curl and the protuberance phenomenon when encapsulate on the air door body was compacted; Favorable sealing property, thus the air balance and effectively distribution in the air conditioning for automobiles case guaranteed.
Below will combine accompanying drawing that the technique effect of design, concrete structure and the generation of the utility model is described further, with purpose, characteristic and the effect of understanding the utility model fully.
Description of drawings
Fig. 1 is the structural representation of existing plane encapsulate air door structure.
Fig. 2 is the broken section structural representation of Fig. 1.
Fig. 3 is the structural representation of the utility model one specific embodiment.
Fig. 4 is the broken section structural representation of Fig. 3.
The specific embodiment
Like Fig. 3, shown in Figure 4, two-way flange encapsulate air door structure one specific embodiment of the utility model is mainly used in and is used for the air conditioning for automobiles case, mainly comprises the air door body 1 with rotation axocoel 11, and air door body 1 is the PP-T40 material.
On air door body 1, utilize quadric injection mould to be formed with two-way flange encapsulate 12, two-way flange encapsulate 12 is thermoplastic rubber (TPE) material.
The plane at two-way flange encapsulate 12 relative air door bodies 1 place with an angle.Be specially, in a side of the hermetically-sealed construction 2 of facing the air-conditioning box housing, the angle between the plane at two-way flange encapsulate 12 relative air door bodies 1 place is the obtuse angle.
In use, owing to be formed with an angle between two-way flange encapsulate 12 and the air door body 1, air door body 1 provides the space of a distortion just when turning to that the closed position is stressed to be compressed, make two-way flange encapsulate 12 by flattening by force.Under the interaction of power, the two-way flange encapsulate 12 in the utility model can make air door body 1 close tightlyer, and sealing property is better.
In concrete the application, the choosing of the turnover angle of above-mentioned two-way flange encapsulate 12 will drive the interference angle that air door body 1 rotates with motion and match.Like this, can be so that hermetically-sealed construction 2 appropriateness of two-way flange encapsulate on the air door body 1 12 and air-conditioning box compress, effectively sealing.
More than describe the preferred embodiment of the utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variation according to the design of the utility model.Therefore, all technical staff in the art according to the design of the utility model on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in determined protection domain by claims.
