The invention relates to the field of electric vehicle motor controller installation, in particular to an installation structure for mounting an electric vehicle motor controller on an integrated cast frame, which comprises a frame and a motor controller, and is characterized in that radiating ribs are arranged on the inner wall of a cavity below a rear bottom fork installation seat and are connected with a left leg arm and a right leg arm in a crossed manner; a motor controller installation column is arranged in a groove formed by cross connection of heat dissipation ribs, the motor controller is provided with an installation base and a motor controller body, the motor controller is fixedly connected with the motor controller installation column on the frame through the installation base, heat dissipation is accelerated through wind power in the driving process, and the problems that an installation structure is poor in heat dissipation performance and poor in heat dissipation effect and installation is tedious are solved.
Description
technical field [0001] The invention relates to the field of installation of electric vehicle motor controllers, in particular to an installation structure in which the electric vehicle motor controller is installed on an integral casting frame. Background technique [0002] The electric vehicle motor controller is an important part of the electric vehicle. It generates a lot of heat in the process of controlling the motor. It is usually installed on the electric vehicle frame, but the current frame is mainly divided into two categories. One type is composed of multiple simple parts through a certain process to form a space frame combination, that is, the space structure type frame, and the other type is a main beam type with a main beam as the main frame and some auxiliary mounting parts. structural frame. Due to the limitation of the current electric vehicle frame, the current electric vehicle motor controller is mostly installed on the outside of the vehicle frame by ins...
