In the use process of the stereo garage, the movement of the automobile tray is driven by a motor, but the waterproof problem of a motor brake is a great problem for the stereo garage built outdoors. The existing gear motor solves the sealing problem of the braking end and the motor, but does not solve the problem that the water seepage in the shell of the braking end is caused by a drainage channel during installation.

For this purpose, chinese patent: the application number is CN201920706130.5, and discloses a sealing structure of a braking end of a special gear motor of a stereo garage, wherein the perpendicular line distance from the inner peripheral surface of a fan housing to the central line of a motor rear end cover is smaller than the perpendicular line distance from the hole wall, close to the central line, of a connecting hole to the central line, so that the fan housing avoids the connecting hole, and water on the outer surface of the motor is prevented from flowing into the fan housing from the connecting hole.

However, in the actual use process, due to the coanda effect of the fluid, water flowing out of the inside of the connecting hole does not drip on the end face of the connecting portion, but flows along the outer surface of the connecting portion, and then flows to the supporting surface through the outer surface of the connecting portion, so that the water flows into the inside of the fan housing through the gap between the connecting portion and the fan housing, and there is still a possibility that water seepage in the brake end housing may occur.

Therefore, we propose a sealing device of a braking end of a special gear motor for a stereo garage to solve the problems.
