Problems solved by technology

The existing electric vehicle controller has the following defects: 1. After a long time of use, the temperature of the electric vehicle controller will continue to rise. If the controller temperature is too high, the components will be damaged, and the heat dissipation capacity of the existing controller Poor; 2. The sealing performance of the existing controller’s shell is not perfect, and a small amount of rainwater will enter the inside of the controller in rainy days or when passing through muddy puddles

Abstract

The invention discloses a CAN communication controller of an electric vehicle. The CAN communication controller comprises a base formed by pressure casting, and a box housing pressed and fastened above the base, wherein an epoxy resin PCB is connected to the base; a 30-pin terminal, a 60-pin terminal, power MOS transistors, a positive phase-crossing flow guide copper sheet and a negative phase-crossing flow guide copper sheet are welded on the epoxy resin PCB in sequence through wave soldering; flow guide copper columns are perpendicularly connected to the epoxy resin PCB; silica gel gaskets are arranged above the power MOS transistors; 6063 aluminum section pressing strips are fixed and locked at the upper ends of the silica gel gaskets by using fixing MOS bolts; a plurality of holes for the flow guide copper columns to penetrate through are formed in the box housing; and silicon rubber seal rings are arranged at the upper ends of the flow guide copper columns. The CAN communication controller has the beneficial effects of good heat dissipation property and good seal property.

Description

technical field [0001] The invention relates to the technical field of controller design, in particular to a CAN communication controller of an electric vehicle. Background technique [0002] In recent years, electric vehicles have been widely used in people's daily life, and the controller of the electric vehicle is the core of the whole vehicle, which is equivalent to the heart of the electric vehicle. The existing electric vehicle controller has the following defects: 1. After a long time of use, the temperature of the electric vehicle controller will continue to rise. If the controller temperature is too high, the components will be damaged, and the heat dissipation capacity of the existing controller Poor; 2. The sealing performance of the casing of the existing controller is not perfect enough, and a small amount of rainwater will enter the inside of the controller in rainy days or when passing through muddy puddles. Contents of the invention [0003] In order to so...
