Integrated motor controller for electric vehicle

Abstract

The invention discloses an integrated motor controller for an electric vehicle. The integrated motor controller comprises a fixed base and a protective cover plate; a shockproof water cooling mechanism, a limiting mechanism and an air cooling mechanism are arranged between the fixed base and the protective cover plate; the shockproof water cooling mechanism comprises a bottom cavity and a side cavity which are arranged in the fixed base, and a water bag is fixedly mounted in the bottom cavity. A nut on a ball screw is used for driving a limiting bolt to move so as to insert and fix the fixed base provided with an integrated circuit assembly, and a driven rack and a limiting plate are arranged on the fixed base; a lifting pressing plate movably abutting against the water bag is arranged through a bearing supporting rod, a low-temperature liquid in the water bag is discharged into a cooling water tank through a drainage pipe under the action of heavy pressure, and a low-temperature conduction effect is achieved for the integrated circuit assembly through a heat conduction plate; a telescopic rod is used for supporting a locking plate to make the locking plate move back and forth, so that a limiting frame which is slidably arranged in the fixed base in a sleeving manner is retracted and fixed, and the protective cover plate is used for providing a protective effect on the integrated circuit assembly.

Description

technical field [0001] The invention relates to the technical field of electric vehicle manufacturing, in particular to an integrated motor controller for electric vehicles. Background technique [0002] Because of the continuous development of science and technology, people's production and lifestyle are constantly innovating. In recent years, in response to the environmental protection call of green travel, more and more groups have begun to choose electric vehicles as transportation tools. Electric vehicles are different from traditional vehicles. The integrated motor controller is mainly used. The motor controller is an integrated circuit that controls the motor to work according to the set direction, speed, angle, and response time through active work. [0003] Under the existing technology, the function of the motor controller is to convert the electric energy stored in the power battery into the electric energy required to drive the motor according to the gear positio...
