Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of new energy vehicles, in particular to a fully sealed structure of a driving motor for a new energy vehicle. Background Art
[0002] With the booming development of new energy vehicles, new energy vehicles are used in different road conditions and environments, which puts higher requirements on the motor. The condensation problem of the motor has gradually emerged. How to solve the condensation problem has become a top priority for each vehicle enterprise.
[0003] The main source of motor condensation is the influence of the inside of the motor and the external environment. Since the external environment of the motor cannot be determined, it is necessary to consider how to avoid the condensation problem at the beginning of the design of the motor itself, and the concept of full sealing emerges as the times require.
[0004] The humidity inside the motor mainly comes from the stator. Therefore, when designing the structure, the stator cavity should be completely separated from the three-phase lines to ensure that there is no insulation failure caused by internal condensation in high and low temperature environments. Summary of the Invention
[0005] The purpose of the utility model is to provide a fully sealed structure of a driving motor for a new energy vehicle, which can ensure that there is no insulation failure caused by condensation in the motor under harsh environments and ensure the reliability of the motor.
[0006] The technical scheme adopted by the utility model is as follows: a fully sealed structure of a driving motor for a new energy vehicle, including a wiring seat and an end cover, the wiring seat is embedded in the end cover; a glue application groove is arranged at the connection between the wiring seat and the end cover, and the glue application groove is arranged on at least one surface of the wiring seat; a three-phase line outlet is opened on the side surface of the wiring seat, and a sealing rubber sleeve is arranged at the three-phase line outlet.
[0007] Further, the glue application groove is arranged at the edge of the wiring seat.
[0008] Further, the glue application grooves on different surfaces are connected to each other.
[0009] Further, extension parts are arranged on both sides of the sealing rubber sleeve, and the extension parts are clamped between an upper pressing plate and a lower pressing plate.
[0010] Further, both the upper pressing plate and the lower pressing plate are part of the wiring seat.
[0011] The beneficial effects of the utility model are as follows: the utility model adds a sealing structure at the three-phase lines of the motor, and at the same time adds a glue application groove at the wiring seat, so that the wiring seat and the motor end cover are sealed by a sealing glue, forming a double-layer seal as a whole.
