Embodiment Construction

[0023] Such as figure 1 As shown, the intelligent drainage device of the present invention includes a control unit 1 , a sensor 2 and a valve 3 . Wherein, the sensor 2 is arranged in the housing 4 of the electric drive module, near the bottom, and is used to detect whether there is liquid water exceeding a threshold amount in the housing 4, and send the monitoring result to the control unit 1 The control unit 1 can be arranged outside the housing 4, and control the opening and closing of the valve 3 according to the detection signal of the sensor 2; On the hole 41, the drain hole 41 is opened according to the control signal of the control unit 1, so that the internal water and impurities can be discharged normally, or the drain hole 41 is closed, so that the external liquid water no longer enters the inside of the housing 4.

[0024] The sensor 2 can be arranged on or near the bottom surface of both sides of the housing 4 in the axial direction, so as to avoid the installatio...

Abstract

The invention relates to an intelligent drainage device, an electrical driving module and a hybrid power automobile. The intelligent drainage device is applied to a shell of an electrical driving module of a purely electrical driving vehicle or a hybrid power vehicle, wherein the shell is provided with a drainage hole arranged at the very bottom. The intelligent drainage device comprises a valve used for closing the drainage hole. The intelligent drainage device further comprises a sensor and a control unit, wherein the sensor is arranged in the shell and used for detecting the water level in the shell, a detection result of the sensor is received by the control unit, and the control unit control open and close of the valve according to the detection result. The drainage hole can be quickly closed in a wading environment, thereby preventing inlet of external water, and effectively keeping the internal environment to be dry. Meanwhile, an enough smooth drainage space can be provided when the drainage hole is open, and blockage of a drainage channel is avoided.

Description

technical field [0001] The invention relates to an intelligent drainage device for an electric drive module in an automobile, the electric drive module and a hybrid electric vehicle using the electric drive module. Background technique [0002] In addition to the traditional internal combustion engine drive, there are also pure electric drive vehicles and hybrid drive vehicles. Pure electric drive vehicles use electric motors as the power source as the name implies, while hybrid vehicles refer to vehicles whose drive system consists of two or more energy sources. A vehicle consisting of a combination of individual drive systems operating simultaneously, powered by a hybrid powertrain with at least two power units. [0003] Whether it is pure electric drive or hybrid drive, the electric motor is used as (one of) the power sources, and the electric motor is different from the traditional internal combustion engine. It uses electric drive instead of 4-stroke fuel combustion, so...
