Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
See Fig. 1, a kind of air conditioning for automobiles HVAC damper movement mechanism, comprises the driving lever 1 of rocking arm 2 and driving rocking arm 2; rocking arm 2 is connected with air door rotating shaft end; driving lever 1 is connected with actuator, and rocking arm 2 is provided with sector 3, and driving lever 1 is provided with the gear be meshed with the sector 3 of rocking arm 2; Gear one end is provided with radial the first baffle plate 5 extended.
The first end of driving link driving lever 1 is connected with actuator and is subject to actuator effect rotatable, with meshed transmission gear between the second end of driving lever 1 and follower rocking arm 2, has higher transmission efficiency and controls precision, and installing easy and simple to handle.The position that driving lever 1 is corresponding with the sector 3 of rocking arm 2 is provided with the first baffle plate 5, can prevent the axial float of rocking arm 2, thus prevents the axial float of air door.
The gear other end is also provided with radial the first baffle plate 5 extended, and sector 3 is limited between two the first baffle plates 5, as shown in Figure 3; First baffle plate 5 at gear two ends is reliably spacing sector 3, accurate positioning, prevents axial float.
The boundary position place, two ends of sector 3 profile of tooth is provided with second baffle 21.The second baffle 21 of sector 3 both sides limits the maximum rotation scope of gear, prevents pinion rotation excessive, causes gears meshing to depart from.
A tooth of sector 3 be axial dimension become large axis wide tooth 8, first baffle plate 5 on be provided with breach 4 with axial corresponding position, wide tooth 8 position, the function of mistake proofing can be played in assembling process.
The axle head that rocking arm 2 coordinates with air door rotating shaft end is at least provided with a reinforcement, can strengthen with air door coordinate intensity, prevent the radial-play of air door.
As shown in Figure 2, it is different with the second reinforcement 7 size with the second reinforcement 7, first reinforcement 6 that rocking arm 2 and the both sides of the axle head that air door rotating shaft end coordinates are respectively equipped with the first reinforcement 6, can play the function of mistake proofing in assembling process.
After adopting above-mentioned structure, with gear teeth meshing transmission between driving lever 1 and follower rocking arm 2, there is higher transmission efficiency and control precision, and install easy and simple to handle, the position that driving lever 1 is corresponding with the sector 3 of rocking arm 2 is provided with the first baffle plate 5, the axial float of rocking arm 2 can be prevented, thus prevent the axial float of air door.The second baffle 21 of sector 3 both sides limits the maximum rotation scope of gear, prevents pinion rotation excessive, causes gears meshing to depart from.First baffle plate 5 at gear two ends is reliably spacing sector 3, accurate positioning, prevents axial float.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
