Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
As shown in Figure 1, Figure 2 and Figure 3, the air door mechanism that this utility model embodiment provides, including air door fixed frame 5, wind
Door 1, rotating driving device 4, drive link 3 and intermediate connecting rod 2.Wherein, air door fixed frame 5 has vent；Air door 1 is arranged
At vent, air door 1 and air door fixed frame 5 are articulated with the first articulated section 15；The body of rotating driving device 4 is fixed with air door
Frame 5 is relatively fixed, and the drive shaft 41 of rotating driving device 4 is provided with locating surface 42；Drive link 3 has drive shaft jack
31, it is provided with the location convex surface 32 matched with locating surface 41 in drive shaft jack 31；Intermediate connecting rod 2 is hinged with drive link 3
In the second articulated section 23, intermediate connecting rod 2 and air door 1 are articulated with the 3rd articulated section 25, drive shaft the 41, first articulated section 15, second
In articulated section 23 and the 3rd articulated section 25, any distance the most therebetween is more than zero.
The air door mechanism that this utility model embodiment provides, due to the 15, second articulated section 23, drive shaft the 41, first articulated section
And the 3rd distance the most therebetween in articulated section 25 more than zero, the drive shaft 41 at rotating driving device 4 drives the company of driving
When bar 3 rotates, drive link 3 drives intermediate connecting rod 2, intermediate connecting rod 2 to drive air door 1, finally realizes air door 1 solid relative to air door
Determine the switch motion of the vent of frame 5.Owing to being provided with locating surface 42 in drive shaft 41, the drive shaft jack 31 of drive link 3
Inside it is provided with the location convex surface 32 matched with locating surface 41, i.e. only need drive shaft 41 is inserted drive shaft jack 31, by fixed
Plane 42 coordinates with location convex surface 32, can be conveniently accomplished the assembling of drive link 3 and drive shaft 41；And, it is ensured that
Drive link 3 is with the situation of drive shaft 41 synchronous axial system, it is ensured that it is accurate that rotating driving device 4 drives that drive link 3 rotates
Property, it is to avoid the two situation about mutually skidding, it is effectively increased the precision controlling air door 1 folding angle, improves control air quantity
Precise degrees.
It is understood that in the 15, second articulated section, drive shaft the 41, first articulated section 23 and the 3rd articulated section 25 any two
Distance between person is any the two axial line distance.Wherein, the 15, second articulated section 23, drive shaft the 41, first articulated section and
The axis of three articulated sections 25 is parallel to each other, and then ensure that rotating driving device 4 drives the operation that air door 1 is opened and closed.Wind

Limiting plate 12.The outer wall of air door fixed frame 5 is air door fixed frame 5 intermediate connecting rod 2 dorsad, rotating driving device 4 and drive link 3
One side.When air door 1 is closed, the outer wall location fit of Guan Bi limiting plate 12 and air door fixed frame 5, it is to avoid air door 1 continues
Guan Bi, effectively prevent air door 1 and closes excessive situation.
In order to improve the drive link 3 rotational stability relative to rotating driving device 4, drive link 3 also includes having
Disk connector 33, drive shaft jack 31 is arranged concentrically with disk connector 33.By above-mentioned setting, improve drive link 3
The weight in the rotation center of circle (disk connector 33 position), and then improve drive link 3 relative to rotating driving device 4
Rotational stability.
In the present embodiment, air door fixed frame 5 has the body with rotating driving device 4 and fix the driving means being connected
Box 54.That is, in rotating driving device 4 is directly anchored to the driving means box 54 of air door fixed frame 5.Can also be solid by connector
Determine rotating driving device 4, e.g., rotating driving device 4 and air door fixed frame 5 be fixed in the housing of total-heat exchanger jointly,
And then reach being relatively fixed of air door fixed frame 5 and rotating driving device 4.
This utility model embodiment additionally provides a kind of total-heat exchanger, and including air door mechanism, air door mechanism is as above-mentioned
Any one air door mechanism.Owing to above-mentioned air door mechanism has above-mentioned technique effect, there is the total-heat exchanger of above-mentioned air door mechanism
Also should have same technique effect, no longer be discussed in detail at this.
As shown in Figures 7 and 8, the outdoor air inlet 7 of the total-heat exchanger in the present embodiment and the air door 1 of air door mechanism are right
Should arrange；When air door 1 reaches maximum relative to the opening angle of air door fixed frame 5, air door 1 sealing chamber external air inlet mouth 7.At this
In embodiment, when air door 1 turns to maximum opening angle 90 °, air door 1 gets final product sealing chamber external air inlet mouth 7, it is achieved Total heat exchange
The indoor air circulation state of device.Further, when air door 1 turns to other angles, air quantity can be regulated to realize different complete
Heat exchange function.That is, the air door mechanism of total-heat exchanger can realize the effect of double-direction control air quantity.
In order to improve the effect of air door 1 sealing chamber external air inlet mouth 7, the inside of total-heat exchanger has and outdoor air inlet 7
The bottom angled face 6 being correspondingly arranged；Air door 1 has and tilts the closed bottom 13 that wind deflector 6 matches.Under in working order,
The main body (air quantity of the vent on damper fixed frame 5) of air door 1 is vertically arranged, and the closed bottom 13 of air door 1
It is horizontally disposed with.For more preferable air intake, the internal backplane of total-heat exchanger is provided with bottom angled face 6, in order to improve into
Air quantity.When air door 1 turns to maximum opening angle 90 °, closed bottom 13 closed bottom inclined plane 6 and outdoor air inlet 7 shape
The opening become.
