Door opening and closing mechanism and instrument desk air outlet with same

Abstract

The invention provides a door opening and closing mechanism which comprises a roller and an opening and closing door. The roller is connected with the opening and closing door through a connecting rod and a rotating shaft arm. The opening and closing door comprises a face blowing air door and a defrosting stop block. One end of the defrosting stop block is fixedly connected with the face blowing air door, the other end of the defrosting stop block is fixedly connected with the rotating shaft arm, the face blowing air door is used for controlling the face blowing air outlet amount. The defrosting stop block is used for controlling the defrosting air outlet amount. The invention further provides an instrument desk air outlet with the door opening and closing mechanism. The door opening and closing mechanism in the instrument desk air outlet adopts the single opening and closing door and a single-connecting-rod structure, the function of simultaneously controlling defrosting and air blowing is achieved, consumption of moving members is reduced as much as possible, the structural space is reduced, and the stability and reliability of the mechanism are greatly enhanced; the number of parts is decreased, so that the mold, part and labor cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of vehicle instrument panels, and specifically designs an opening and closing mechanism and an instrument panel air outlet with the opening and closing mechanism. Background technique [0002] On the instrument panel of some current vehicles, in addition to being equipped with blowing air outlets to provide hot and cold air for the occupants of the vehicle, it is also equipped with left and right defrosting grilles, which are located at the air outlet grilles on the left and right sides of the instrument panel, and are mainly used for air conditioning. The air outlet is guided, and the exported wind is used to remove frost and fog in the area of ​​the rearview mirror on the left and right side windows. The structure of the air outlet generally includes rollers and an opening and closing door. The opening and closing door is installed inside the connecting air duct (inlet air passage of the air outlet). By co...

AI Technical Summary

Problems solved by technology

Although the existing surface blowing outlet with integrated defrosting control function can realize the integrated control function of the blowing surface air outlet and the left and right defrosting outlets, due to the use of the double opening and closing door control mechanism, there is a need for a gap between the two opening and closing doors and the rollers. Two connecting rods are connected to realize the function, and the whole mechanism includes 4 kinematic pairs (between the roller 11 and the connecting rod 12 of the surface blowing door, between the connecting rod 12 of the surface blowing door and the opening and closing door 13 of the surface blowing control, between the surface blowing control Between the opening and closing door 13 and the defrosting door connecting rod 15, between the defrosting door connecting rod 15 and the defrosting control opening and closing door 14), the components of this kind of movable connection are not only required to have high machining accuracy of the mating surface, but the key is the mechanism Poor stability, the consequence of this poor stability is that the tuyere opening and closing mechanism is prone to failure, the production scrap rate is high, and the finished product failure rate is high
