As shown in fig. 1 and 2, in a specific embodiment, the motor ventilating structure of the wiper motor of the automobile may generally include a motor 1, a transmission case 2, and a ventilation hole 3. The motor 1 is arranged inside a cover of the automobile, the motor shell 1-1 is arranged outside the motor 1, and the motor 1 is connected with a power supply inside the automobile and used for driving the motor 1. The gearbox 2 is arranged on the side part of the motor shell 1-1, is connected with the motor 1 and is used for driving the gearbox 2, and the gearbox 2 comprises a gearbox shell 2-1 and a gearbox cover plate 2-2 arranged on the top of the gearbox shell 2-1. The air vent 3 is arranged in the middle of the gear box cover plate 2-2, and an air vent cover 3-1 is arranged on the air vent 3. The air holes 3 are provided with air permeable films 3-2 for water resistance and air permeability.

The air holes 3 are formed in the middle of the cover plate 2-2 of the gearbox, the breathable films 3-2 are installed on the air holes 3 and used for water proofing and ventilation, the convex rings 3-3 are arranged outside the air holes 3 and protrude towards the outside of the air holes 3, internal and external pressure is balanced, internal heat is released, the breathable films 3-2 can be pressed through a tool, installation efficiency of the breathable films 3-2 can be effectively improved, the breathable films are not prone to wading, and therefore damage to the motor 1 is avoided.

Optionally, the motor housing 1-1 is sleeved outside the motor 1 and fixed inside the automobile cover through bolts, so as to fix the motor 1 and facilitate disassembly, assembly and maintenance.

Wherein, the gearbox shell 2-1 is fixed on the side part of the motor shell 1-1 through bolts, which is convenient for disassembly and maintenance.

Wherein, the air permeable membrane 3-2 is bonded with the air holes 3 through glue.

Alternatively, the gas permeable membrane 3-2 may be a polymer compound obtained by polymerizing tetrafluoroethylene, and has excellent chemical stability and corrosion resistance.

In the present embodiment, preferably, the airing hole 3 is circular.

In the embodiment, a convex ring 3-3 protruding to the outside of the vent hole 3 is further arranged on the outside of the vent hole 3 to increase the height of the vent hole 3, so that the breathable film 3-2 is convenient to install.

In this embodiment, it is preferable that the vent cover 3-1 is screw-mounted on the collar 3-3, and the vent cover 3-1 is adapted to the shape of the collar 3-3, and generally, the collar 3-3 and the vent cover 3-1 are both circular.

Wherein the height of the convex ring 3-3 is 0.5-1.5 CM.
