Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 As shown, the motor controller is composed of a capacitor component 1 , a power module assembly 2 , a module cover assembly 3 and an outlet cover 4 . The capacitive component 1 is used as a supporting component of the controller and is located at the bottom of the motor controller. The power module assembly 2 is located right above the capacitive component 1 and fixed on the capacitive component 1 . The module cover plate assembly 3 is a hollow structure, and is connected with the capacitor component 1 through the mounting holes around it. An outlet cover 4 is installed above the module cover assembly 3 .

[0027] The capacitive component 1 , the module cover assembly 3 and the outgoing line cover 4 constitute a controller casing; the outer surface of the capacitor casing 101 of the capacitive component 1 is provided ...

Abstract

The invention relates to an electric vehicle motor controller structure. The electric vehicle motor controller structure includes a capacitor component (1), a power module assembly (2), a module cover plate assembly (3) and a wire outgoing cover plate (4); the capacitor component (1) is adopted as a supporting component for the motor controller and is located at the bottommost portion of the motor controller; the power module assembly (2) is located directly above the capacitor component (1) and is fixed onto the capacitor component (1); the module cover plate assembly (3) is of a hollow structure and is connected with the capacitor component (1) through mounting holes at the periphery of the module cover plate assembly (3); the wire outgoing cover plate (4) is arranged above the module cover plate assembly (3); the capacitor component (1), the module cover plate assembly (3) and the wire outgoing cover plate (4) form a controller housing; and the outer surface of the capacitor housing (101) of the capacitor component (1) is provided with mounting legs for fixing the motor controller.

Description

technical field [0001] The invention relates to a structure of a motor controller in the field of electric vehicles. Background technique [0002] As the country pays more and more attention to environmental protection and energy issues, the development of new energy electric vehicles is gradually accelerating. The electric drive system is the core of electric vehicles. As a key component of the electric drive system, the motor controller needs to have good waterproof, heat dissipation, and shockproof performance. With the maturity of the motor controller, the size of the power density has been paid more and more attention. Therefore, the structure of the motor controller needs to be continuously improved. [0003] Chinese patents CN201520891524.4, CN201520005101.8 and CN201120222659.3 provide several different electric vehicle motor controller structures, the overall layout of which is roughly the same, and its main features are: [0004] (1) The support capacitor and th...
