The invention discloses an automobile air conditioner mode air door driving mechanism and a heater shell in the technical field of automobile spare parts, the automobile air conditioner mode air door driving mechanism comprises a driving plate, three track grooves are formed in the driving plate, driving lever pieces are movably arranged in the track grooves, and the driving lever pieces are in transmission connection with rotating shafts of a face blowing air door, a foot blowing air door and a defrosting air door respectively. The shifting rod piece comprises a rod body, a mounting frame arranged at the end of the rod body and a plurality of rolling bodies arranged on the outer ring of the mounting frame, all the rolling bodies are evenly distributed along the same circumferential line, the diameter of the circumferential line where all the rolling bodies are located is equal to the width of the track groove, and the shifting rod piece makes rolling contact with the groove walls of the two sides of the track groove through the rolling bodies. According to the driving mechanism, a completely matched rolling contact mode is adopted between the deflector rod piece and the track groove, so that the guide precision of the track groove can be greatly improved, the angle control precision of air doors in various modes is ensured, and meanwhile, the problems of blockage, groove wall abrasion, abnormal sound and the like can be avoided.
本发明公开了汽车配件技术领域中的一种汽车空调模式风门驱动机构及加热器壳体,包括拨盘,所述拨盘上设有三条轨迹槽,所述轨迹槽内均活动设有拨杆件,所述拨杆件分别与吹面风门、吹脚风门和除霜风门的转轴传动连接,所述拨杆件包括杆体,以及设于杆体端部的安装框,以及设于安装框外圈的若干个滚动体,所有滚动体沿同一圆周线均匀分布,且所有滚动体所在圆周线的直径等于轨迹槽的宽度,所述拨杆件通过滚动体与轨迹槽的两侧槽壁滚动接触。该驱动机构中拨杆件与轨迹槽之间采用完全匹配的滚动接触方式,其可大幅提高轨迹槽的导向精度,从而保证各模式风门的角度控制精确性,同时可避免卡顿、槽壁磨损、异响等问题。
