Abstract

The invention relates to a controller for electric vehicle, comprising an outer housing and a circuit board mounted in the outer housing, a triode bar, a constantan wire and high current leads, an opening is provided on the edge side of the outer housing, the opening is sealed by a cover board, a mounting plate for mounting the controller on the electric vehicle is provided on one side of the outer housing, a heat radiation slot is arranged on the external side of the other side wall opposite to the mounting plate of the outer housing, characterized in that, the opening and the mounting plate of the outer housing are positioned on the same side, the circuit board is mounted in the outer housing and is fixedly connected with the side wall opposite to the opening of the outer housing by screw nails, the triode bar and the circuit board are in parallel welding, the triode bar and the side wall opposite to the opening of the outer housing is attached tightly. Compared to the prior art, the invention has good heat radiation performance and convenient assembling.

Description

technical field [0001] The invention relates to an electric vehicle controller. Background technique [0002] The existing electric vehicle controller casing is usually made of aluminum and is in the shape of a cuboid. There are many cooling grooves on its surface, and its front and rear ends (referring to the two ends of the cuboid with the smallest surface area) are closed with front and rear covers. , the wire passes through one of the front and rear covers on the circuit board and is exposed outside the housing, and the circuit board in the housing is fixed by screws on the side wall of the housing (referring to the second smallest wall surface). In order to solve the heat dissipation problem and facilitate the installation and fixing of the circuit board, it is necessary to fix the heat-conducting aluminum strip on the circuit board first (the heat-conducting aluminum strip is installed vertically with the circuit board), and then the circuit board is screwed to the sid...
