Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor ventilation components, in particular to an improved waterproof ventilation membrane protection structure. Background Art
[0002] A ventilation component is installed on the frame that contains electrical components such as motors, sensors, switches, and ECUs (electric control units). The ventilation component ensures ventilation between the inside and outside of the frame, alleviates pressure changes inside the frame caused by temperature changes, and prevents foreign matter from entering the frame.
[0003] At present, the breathable film is basically attached to the outer surface of the frame of the electrical component or a separate breathable component is added. In order to prevent the breathable film attached to the outer surface of the frame of the electrical component from being damaged, it is necessary to add another protective device on the breathable film. Whether adding another protective device on the breathable film or adding a separate breathable component, the cost is increased. In addition, in order to increase the ventilation area, the current breathable holes are all made larger, and the required protective device is also larger, which also increases the cost.
