Anti-deformation structure for air door shafts of air conditioner

Abstract

The invention provides an anti-deformation structure for air door shafts of an air conditioner. The anti-deformation structure comprises a first air door, a second air door, a first rotating shaft, a second rotating shaft and a third rotating shaft, wherein the first air door and the second air door are provided with first rib plates, second rib plates, a plurality of third rib plates and fourth rib plates; inclination directions of the two adjacent fourth rib plates are the same; the first rotating shaft, the second rotating shaft and the third rotating shaft are connected between the first rib plates and the second rib plates; one ends of the third rib plates intersect the first rib plates; the other ends of the third rib plates intersect the second rib plates, and stretch out of the outer parts of the second rib plates; the height of the parts, stretching out of the outer parts of the second rib plates, of the third rib plates is gradually decreased till the parts intersect the first air door or the second air door; and the fourth rib plates are arc-shaped. According to the anti-deformation structure, a product can be prevented from deforming due to shrinkage while the product strength is guaranteed and the product reliability is improved, besides, the self weight of the product can be decreased, and the production cost of the product is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted air conditioners, in particular to an anti-deformation structure for an air conditioner damper shaft. Background technique [0002] The automotive air conditioning system is a device that cools, heats, ventilates, and purifies the air in the cabin. It can provide a comfortable environment for passengers, reduce driver fatigue, and improve driving safety. The air conditioning unit has become one of the symbols to measure whether the car is fully functional. During the rotation of the automobile air-conditioning damper, the strength must be sufficient to overcome the influence of wind pressure; however, the rotating part of the air-conditioning damper in the prior art directly uses a cylindrical structure, which is prone to shrinkage and deformation of the product due to excessive thickness of the material. [0003] Therefore, it is necessary to provide an anti-deformation structure for the...
