The air door includes：Both ends are equipped with the door-hinge and door-plate of air door spiral position limiting structure, wherein：Two air door spiral shells
Rotation position limiting structure is in contact with intermediate bulkhead and distribution tank shell to realize that the multidirectional rotary of air door, door-plate are set to air door respectively
Both sides, with door-hinge it is perpendicular while it is parallel with air port to cover air outlet open area.
The door-plate is equipped with the matched flexible glue structure of flange face on distribution tank shell to realize sealing.
The shell spiral branch of corresponding air door spiral position limiting structure is respectively equipped on the distribution tank shell and intermediate bulkhead
Support structure and intermediate bulkhead spiral support structure.
The shell spiral support structure and intermediate bulkhead spiral support structure is preferably ramp structure.
Technique effect
Compared with prior art, the present invention realizes conversion of the air door on different sealing directions, by this conversion,
The patency that air-conditioning distributor box inner flow passage can be effectively improved makes wind because of the space hold without traditional strip air door
Amount is improved, and linear temperature increase controls more preferable, because vertical angle is presented in sealing direction and the damper movement direction of the design,
The resistance that wind pressure generates damper movement when air door is closed is efficiently avoided, the driving force in air door closing process is made to reduce

Specific implementation mode
As depicted in figs. 1 and 2, it is a kind of spiral damper unit for lateral seal that the present embodiment is related to, including：Distributor box
Shell 1, intermediate bulkhead 2 and it is movably set in air door 3 therebetween and across distribution tank shell 1 and the wind that is connected with air door 3
Door rocking arm 8.
As shown in Figure 3 and Figure 4, the throttle rocker 8 includes：Rocker arm body 17 is set to 17 side of rocker arm body
Rocking arm buckle 10 and be set to the other side be connected with driving mechanism with dowel pin 18, wherein：Rocking arm buckle 10 be set to
The rocking arm fixed structure 9 distributed on tank shell 1 is clamped.
As shown in Fig. 5~Fig. 7, the air door 3 includes：Both ends are equipped with the door-hinge 15 of air door spiral position limiting structure 13,14
And door-plate 16, wherein：Air door spiral position limiting structure 13,14 is in contact with intermediate bulkhead 2 and distribution tank shell 1 to realize respectively
The Multidirectional motion of air door 3, door-hinge 15 are fixedly connected by intermediate bulkhead spiral support structure 7 with door-plate 16.
As shown in figures 9 a and 9b, the rocker arm body of the throttle rocker is further connected with drive component, the driving
Component includes：Connecting rod 19, track disk 20, holder and motor.
The door-plate 16 is equipped with the matched flexible glue of flange face 5 on distribution tank shell to realize sealing.
As shown in figure 9, the air door spiral position limiting structure 13,14 is internally provided with air door splined hole 12；Described in correspondence
Rocker arm body 17 be equipped with spline 11, the splined hole 12 of spline 11 and air door coordinates.
The Multidirectional motion refers to：Air door 3 is opening and closing position, and air door uses rotary motion, while axially producing
Raw displacement, to ensure the leakproofness of air door, displacement is sealing interference standard volume and air door shell coordinates the sum of axial gap, excellent
2.5~4 degree are selected as, corresponding 1.8~2.2mm, the standard single sided 0.6mm of body clearance.
The distribution tank shell 1 is equipped with air port 4, and 16 shape of door-plate on air door 3 matches with air port 4, and air door
The door-plate flexible glue 5 of interference fit is further provided on 3 to improve leakproofness.
As shown in fig. 7, being respectively equipped with corresponding air door spiral position limiting structure on the distribution tank shell 1 and intermediate bulkhead 2
14,13 shell spiral support structure 6 and intermediate bulkhead spiral support structure 7.
The shell spiral support structure 6 and intermediate bulkhead spiral support structure 7 is arc wedge structure, specific shape
Shape structural requirement is：Be set to arc wedge structure both ends has two sections of planes respectively, is formed as 5 degree of rotation angle, acts on respectively
It is rotated to locking when opening and closing position in air door, avoids air door angular deviation caused by Mechanism Clearance, the arc
Wedge structure is depending on the rotation angle of air door, it is assumed that air door rotation angle is A, and arc wedge structure should subtract both ends locking plane
For A-2*5 degree, and assume that axle of the air door to displacement is B, and arc wedge is calculated by rotation angle A and axial displacement B
Slope.When air door 4 is rotated to different angle, air door spiral position limiting structure 13,14 and shell helical structure 6,7 contacts, by
Air door 4 is set to carry out Y-direction movement when rotated in different displacements in Y-direction in helical structure 6,7.
As shown in figure 9, being clearance fit between the air door 3 and throttle rocker 8, preferred design gap should be unilateral
0.05-0.1mm。
Present apparatus specific work process is as follows：External driving mechanism is coordinated by parts such as motor, mode dial, connecting rods to be driven
Rocking arm 8 rotates, and rocking arm 8 drives air door 3 to do identical rotary motion, while rocking arm 8 and shell 1 by spline fitted
On rocking arm fixed structure 9 pass through buckle 10 fix so that rocking arm 8 is all held axially fixed when doing any movement, works as wind
When door 3 is rotated by the drive of rocking arm 8, helical structure 6 and 7 is respectively equipped on shell 1 and intermediate bulkhead 2, structure is in arc
Spiral position limiting structure 13,14 on shape wedge, with air door 3 contacts, due to the structural principle of arc wedge so that air door 3 is at different angles
When spending, axial to generate displacement, displacement stroke causes air door door-plate 16 and door-plate flexible glue 5 to be contacted with shell 1, and further generates
Interference fit makes its deformation to realize the sealing function of air-conditioner air outlet since the elastic principle of flexible glue 5 is non-rigid contact.
