Vehicle air conditioning unit

Abstract

A vehicle air conditioning unit includes: a slide door which controls an opening ratio of an opening allowing an air stream to flow therethrough; a deflection suppressing portion which suppresses a deflection of the slide door by pressing the slide door; and a vibration suppressing portion which suppresses the amplitude of a vibration of the slide door generated when the slide door is exposed to the air stream.

1 . A vehicle air conditioning unit comprising:
 a slide door which has an opening and is adopted to control an opening ratio of the opening allowing an air stream to flow therethrough;   a deflection suppressing portion which is adopted to suppress a deflection of the slide door by pressing the slide door; and   a vibration suppressing portion which is adopted to suppress an amplitude of a vibration of the slide door generated when the slide door is exposed to the air stream.   
     
     
         2 . The vehicle air conditioning unit according to  claim 1 , wherein the vibration suppressing portion comes into contact with the slide door from a downstream side of the air stream when the slide door is vibrated. 
     
     
         3 . The vehicle air conditioning unit according to  claim 1 , wherein the vibration suppressing portion is provided apart from the deflection suppressing portion, and the deflection suppressing portion and the vibration suppressing portion are disposed in the whole width of the slide door at a nonuniform interval. 
     
     
         4 . The vehicle air conditioning unit according to  claim 2 , wherein the vibration suppressing portion is provided apart from the deflection suppressing portion, and the deflection suppressing portion and the vibration suppressing portion are disposed in the whole width of the slide door at a nonuniform interval. 
     
     
         5 . The vehicle air conditioning unit according to  claim 1 , wherein a plurality of the deflection suppressing portions is disposed in a width direction of the slide door, and the vibration suppressing portion is disposed between the deflection suppressing portions. 
     
     
         6 . The vehicle air conditioning unit according to  claim 2 , wherein a plurality of the deflection suppressing portions is disposed in a width direction of the slide door, and the vibration suppressing portion is disposed between the deflection suppressing portions. 
     
     
         7 . The vehicle air conditioning unit according to  claim 1 , wherein the slide door is slidable by a rack-and-pinion system including a rack and a pinion, a thickness of the slide door is 1 mm or less, and the rack is integrally formed with the slide door. 
     
     
         8 . The vehicle air conditioning unit according to  claim 2 , wherein the slide door is slidable by a rack-and-pinion system including a rack and a pinion, a thickness of the slide door is 1 mm or less, and the rack is integrally formed with the slide door.
