[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle air-conditioning dial operating device for opening and closing a shutter valve by operating a dial provided on a side surface of an air-conditioning case.

[0002]

2. Description of the Related Art FIGS. 4 to 8 show a conventional dial operating device for vehicle air conditioning. Reference numeral 20 denotes an air-conditioning case, to which a dial 21 is rotatably mounted on a side surface and protrudes from the front surface of the finisher 22. A link mechanism 23 connects the dial 21 and the shutter valve 24. Dial 2
(1) A notch 25 is formed on a part of the outer periphery, and
Are provided facing inward in the circumferential direction.
Is protruding. An arc-shaped stopper 28 is provided at the center of the rotation locus of the notch 25 and fixed to the air-conditioning case 20, and a projection 29 is protruded at the center of the outside. Reference numeral 30 denotes a horizontal louver.

Next, the operation will be described. Dial 21
Is rotated up and down, the shutter valve 24 is rotated via the link mechanism 23 to open and close the air passage in the air conditioning case 20. When fully opened and fully closed, the projection 27 of the bullet 26 rides over the projection of the stopper 28, and the operation ends.

[0004]

In the above prior art, when the force of the fingertip for rotating the dial 21 is weak, the projection 27 of the bullet 26 abuts the projection 29 of the stopper 28 as shown in FIG. Sometimes the illusion that the operation has been completed is made and the fingertip is released. Thus, the shutter valve 24 had problems points that may arise from malfunction of being held in the B position does not reach the fully closed state of the front of the fully closed state A.

SUMMARY OF THE INVENTION A vehicle air conditioning die according to the present invention.
The dial operation device aims to solve the above problems,
In a vehicle air-conditioning dial operating device in which a dial provided on a side surface of an air-conditioning case and a shutter valve are connected by a link mechanism, a fan-shaped hollow portion is formed on the dial, and a rotation locus of the hollow portion Inside, an arc-shaped stopper fixed to the air-conditioning case protrudes, and the shutter valve is fully opened.
It as both ends of the recessed portions in synchronization with the fully closed abuts alternately at both ends of the arc-shaped stopper, outside the recessed portions of the dial
A torque output member protrudes from the inner surface of the side arc-shaped part, and this is
When the shutter valve rotates, the outer arc is elastically deformed.
Pressing and sliding along the outer surface of the arc-shaped stopper
The torque output of the dial is performed by means of

1 to 3 show an embodiment of the present invention . 1
The dial 2 is rotatably mounted on a side surface of an air-conditioning case, and protrudes from the front surface of the finisher 3. Reference numeral 4 denotes a link mechanism that connects the dial 2 and the shutter valve 5. A fan-shaped hollow portion 6 is formed on the dial 2, and the air-conditioning case 1 is provided in a rotation locus of the hollow portion 6 when the dial 2 rotates between a fully closed position and a fully opened position of the shutter valve 5.
An arc-shaped stopper 7 fixed to is protruded. And
Synchronizing with the full opening and full closing of the shutter valve,
Both ends should alternately contact both ends of the arc-shaped stopper
That it is set to. An arc-shaped torque output member 9 is provided at the center of the inner surface of the outer arc-shaped portion 8 of the lightening portion 6.
This torque output member 9 is used when the shutter valve 5 rotates.
The outer stopper 8 is elastically deformed while the outer stopper 8 is
Is slid along the outer surface of the slab.

Next, the operation will be described. When the dial 2 is turned up and down, the shutter valve 5 is turned through the link mechanism 4 to open and close the air passage in the air conditioning case 1.
During the rotation of the shutter valve 5, the torque output member 9 is pressed and slid along the outer surface of the arc-shaped stopper 7 as a sliding member while elastically deforming the outer arc-shaped portion 8, whereby the fingertip is moved.
Gives a certain resistance to the turning operation of the dial 2 by the
Feeling improves. Further, when the shutter valve 5 is fully opened and fully closed, one end of the lightening portion 6 comes into contact with one end of the arc-shaped stopper 7 and stops .
Is different from that which decreases after increasing the pressure
Incorrect position of shutter valve due to malfunction
There is no stop.

[Effect of the invention] Dial operating device for vehicle air conditioning of the present invention
In a vehicle air-conditioning dial operating device in which a dial provided on a side surface of an air-conditioning case and a shutter valve are connected by a link mechanism, a fan-shaped hollow portion is formed on the dial, and rotation of the hollow portion is performed. an arcuate stopper fixed to the air conditioning case in a kinematic trajectory is projected, fully open the shutter valve, both ends of the recessed portions in synchronization with the fully closed to as contacting alternately ends of the arcuate stopper of the dial Meat removal
A torque output member protrudes from the inner surface of the outer
When the shutter valve rotates, the outer arc is elastically deformed.
While sliding along the outer surface of the arc-shaped stopper.
The torque of the dial.
Gives a certain resistance to the rotation of the dial with the fingertip.
Well, the operation feeling is better. Also, the shutter
When reaching the fully open / closed position, it is an illusion that the operation has been completed.
If you release your fingertips and the fully open and fully closed movements become uncertain
Problem can be prevented.
