Drainage structure for automobile motor

Abstract

The invention discloses a drainage structure for an automobile motor; a shell is formed by fixedly connecting an outer shell arranged at the outer side of the automobile motor with an end cover; based on the working state of the motor, at least one through drain hole is arranged in the shell at the lowest part of the motor; the drain hole is of a funnel shape, and the diameter of an opening at the lower end of the funnel shape is larger than that of an opening at the upper end of the funnel shape; the drainage structure is provided with a sealing plug made of elastic material; the sealing plug is movably inserted in the drain hole and is capable of moving the set distance along the axial direction of the drain hole; the specific structure comprises: the lower segment of the drain hole is a thread hole, a drain bolt is also arranged and screwed with the thread of the drain hole; the upper end of the drain bolt is pressed against the lower end of the sealing plug; the drain bolt is provided with a drain structure for communicating the outside with the drain hole; and the maximum radial external diameter of the sealing plug is larger than the minimum radial internal diameter of the drain hole. The drainage structure for the automobile motor is capable of draining and sealing by the axial movement of the sealing plug, so that the functions of automatically and smoothly discharging the water inside the motor as well as stopping and sealing the water outside the motor can be effectively realized, and the motor is better protected; and the accidents caused by the insulation problem can be avoided, so that the motor is safer in use.

Description

technical field [0001] The invention relates to a motor structure, in particular to a vehicle motor drainage structure. Background technique [0002] Electric vehicle motors, electric motorcycle motors and automobile motors operate in various environments. After wind and rain, it is common to pass through ponds. Water intake and drainage, waterproof and sealing are necessary measures to ensure the normal operation of the motors; in addition In addition, the motor may also produce condensed water under various climatic conditions, all of which will seriously damage the motor insulation and cause accidents. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a vehicle motor drainage structure, which has a simple drainage structure, good drainage and sealing effects, and is easy to use. [0004] The technical solution adopted by the present invention in order to solve the technical problem is: a vehicle motor drai...
