AIR-CONDITION CONTROL DIAL OF A VEHICLE, CAPABLE OF OPERATING A CONTROL DOOR OF A HEATING-VENTILATION-AND-AIR CONDITIONING SYSTEM

摘要

PURPOSE: An air-condition control dial of a vehicle is provided to improve the un-uniformity of an effort per a section which a user feels when operating an operating knob of the air-condition control.;CONSTITUTION: An air-condition control dial of a vehicle comprises a rotary lever(300), an elastic unit(500), and a rotary guide(700). The rotary lever is rotated by being interlocked with an operating knob(100), and a rotating end(320) of the rotary lever is connected to an HVAC(Heating, Ventilation, and Air Conditioning) system with a wire ring. The elastic unit is installed on one end of the rotary lever. The rotary guide is closely adhered to the elastic unit along a rotating radius of the end of the rotary lever, and projections(720) are gradually formed in the surface where the rotary guide is adhered along the rotating radius so that elastic power which is different per a step is stored in the elastic unit and the operating power of the operating knob becomes uniform.;COPYRIGHT KIPO 2013
