Problems solved by technology
After the motor assembly was disassembled in the rain, a little water droplets were found on the stator core, stator end cover, and rotor core, and the water resistance was poor.
In order to avoid this unfavorable situation, only high waterproof grade external rotor motors can be used in the prior art.
However, the higher the waterproof level of the external rotor motor, the higher its structural complexity, processing difficulty, and cost.
Therefore, this method is less cost-effective

Embodiment Construction
[0035] According to the actual needs of roof-mounted vehicle air conditioners, the applicant first considered how figure 1 The shown structure of a motor base with waterproof function proves that it can greatly reduce the amount of water splashed into the interior of the motor assembly (such as between the motor base and the fan blade), thereby providing a higher waterproof level at a lower cost .
[0036] However, for this motor base structure, when a small amount of water a1 falls into the motor base from the gap a2 between the motor base and the fan blades, the water will be difficult to discharge. 5°C, -7°C) test, the water a3 that is not discharged in time is easy to freeze, and the amount of freezing will gradually increase, so when the motor a5 drives the fan blade a4 to rotate, it may cause impact and damage the fan blade.
[0037] Therefore, the first aspect of the present invention provides an improved motor seat structure, which can prevent flying water from enteri...

The invention discloses a motor base. The motor base is used for fixing an outer rotor motor, wherein a fan blade is arranged on a rotor of the outer rotor motor; the motor base comprises a bottom plate and a folding edge; the folding edge is located on the side, toward the motor, of the bottom plate; and notches are distributed at the connected part of the folding edge and the bottom plate and run through the bottom plate and / or the folding edge of the motor base. The motor base disclosed by the invention can easily discharge water entering an assembly gap when reducing the water entering the assembly gap, so that the water can be prevented from entering the outer rotor motor after the motor base and the outer rotor motor are arranged in a fitting manner; and short circuit and burn-out accidents of the motor are avoided. The invention further discloses a motor component and an overhead-type vehicle air conditioner.
Description
technical field [0001] The invention relates to a motor base. The present invention also relates to a motor assembly with the aforementioned motor base and a top-mounted vehicle air conditioner. Background technique [0002] On the premise of ensuring stable performance and reliable operation, the outer rotor motor used in the air conditioner of a roof-mounted vehicle (such as a caravan) also needs to have the function of preventing rain, car washing and other harsh vehicle environments. The traditional outer rotor motor is waterproof only by its own waterproof structure, but in relatively harsh environments (such as storms or car washes, etc.), some water will always splash on the outer surface of the outer rotor motor, and the water on the outer surface will With the high-speed rotation of the motor, it may enter the interior of the motor, which may easily cause a short circuit of the motor. [0003] This type of external rotor motor is usually fixed on the chassis of th...
