A waterproof connection structure for a new energy vehicle motor is provided, which includes: a bearing pressure plate, one side surface of which is provided with a boss and a groove, the groove is circumferentially arranged around the boss, and the boss is arranged There are blind holes; the cover plate is arranged on the one side surface of the bearing pressure plate, and the cover plate is provided with a counterbore, the counterbore is corresponding to the position and number of the boss, and the counterbore can accommodate the boss a connecting piece, arranged in the counterbore and the blind hole, the bearing pressure plate and the cover plate are connected through the connecting piece; and a sealing piece, which is arranged in the groove, and is located between the bearing pressure plate and the cover plate between the covers. Rotate the bearing pressure plate, when the boss and the counterbore correspond to match, the assembly efficiency is improved, and there is no risk of water leakage in the thread gap.
Description
Technical field [0001] The present invention relates to a waterproof connection structure for a new energy automotive motor, belonging to the field of new energy automotive motor manufacturing. Background technique [0002] At present, in the structural design of new energy automotive motor, the front end bearing is a fixed end, typically using the bearing pressure plate pressurizing bearing ring as an axial positioning, and fastened with a rush of a wrapped screw. For example, Chinese patent ZL201820196572.5 discloses a positioning structure of a bearing pressure plate including a motor end cap and a bearing pressure plate; the motor end cover has a bearing chamber that houses the bearing; the bearing pressure plate is packaged outside the bearing chamber And connect to the motor end cover for axial positioning of the bearing; wherein the periphery of the bearing chamber on the motor end is provided with a first positioning member, set on the axial pressure plate. There is a sec...
