The invention relates to an automobile air conditioner blower motor end cover. The problem that squeak abnormal noise is generated when a commutator in a motor of an existing automobile air conditioner blower is directly blown by cold air is mainly solved. The commutator is characterized in that an air inlet baffle (6) is arranged on the bottom plate (2) between the air inlet window (4) and the bearing mounting hole (5), the radian of the air inlet baffle (6) is not smaller than that of the air inlet window (4), and the height of the air inlet baffle (6) is not smaller than the length of the commutator. The air inlet baffle is arranged and corresponds to the air inlet window for direct blowing of cold air, so that direct blowing of the cold air to the commutator can be effectively avoided, the service life of the commutator is prolonged, meanwhile, heat exchange in the end cover is not affected, heat dissipation of the motor is taken into consideration while abnormal noise is eliminated, and the service life of the commutator is prolonged. The motor has the characteristics of simple structure, low cost and long service life.
本发明涉及一种汽车空调鼓风机电机端盖。主要解决了现有的汽车空调鼓风机电机中的换向器被冷空气直吹会产生“吱吱”异响噪声的问题。其特征在于:所述进风窗口(4)与轴承安装孔(5)之间的底板(2)上设有进风挡板(6),所述进风挡板(6)的弧度不小于进风窗口(4)的弧度,所述进风挡板(6)的高度不小于换向器的长度。本发明设置了进风挡板,进风挡板与冷空气直吹的进风窗口相对应,能够有效避免冷空气对换向器直吹,提高了换向器使用寿命,同时不影响端盖内的热量交换,在消除了异响噪声的同时兼顾了电机散热,具有结构简单、成本低及电机使用寿命长的特点。
