Problems solved by technology

[0009] This structure has several disadvantages: First, the heat dissipation effect of the plastic shell material is poor. The combined structure of half of the plastic shell and half of the aluminum alloy shell makes the overall heat dissipation surface area of ​​the controller smaller because it is difficult for plastic to conduct heat compared to metal; The second is that the sealing rubber pad installed in the controller structure and the split junction needs continuous pressing force to maintain the seal, while the mechanical strength of the plastic structural shell is low, and the plastic is prone to irreversible deformation when subjected to high temperature, and loses the sealing property. The required continuous pressing force; the third is that the plastic shell is not conducive to shielding the controller from electromagnetic interference; the fourth is the split structure of the plastic shell and the aluminum alloy heat dissipation shell, there are many sealing points, the sealing is difficult, and the waterproof effect is not good

Abstract

An electric vehicle controller provided by the present invention includes a casing, a terminal block, a pin socket, a circuit board and an end cover; the casing is made of stretched profiles, and the outer surface of the casing is divided into a flat surface and a heat dissipation rib surface. On the flat surface of the body, the upper two ends of the housing are respectively provided with a wiring seat gap to install the wiring seat, and the side of the housing is provided with a control line pin header socket hole to install the pin header socket; The cavity, corresponding to the notch side of the terminal block in the upper part of the shell, is provided with a rib for positioning the terminal block, and in the bottom or two sides of the shell, there is a perforated channel for installing the positioning member of the circuit board; The body is provided with a heat-conducting surface that fits the power tube; most of the exterior of the shell is provided with heat dissipation ribs. This structural design solves the contradiction between the two existing technologies, with simple and ingenious structure, good workmanship, high heat dissipation performance, low cost, and waterproof. It is reliable, and also plays the role of electromagnetic shielding; it improves the quality and standardization of electric vehicles, reduces the cost of the whole vehicle manufacturing process, and facilitates future maintenance.

Description

technical field [0001] The present invention relates to the technical field of electric vehicles, and more particularly, to a controller of an electric vehicle. Background technique [0002] The electric vehicle controller is one of the four important parts of an electric vehicle. It is the "brain" of the electric vehicle. It controls the start, operation, advance, retreat, speed, and stop of the electric vehicle. If the electric vehicle has a problem with the controller, it will be difficult to move. [0003] Among electric vehicles, the annual output of two-wheeled bicycles as means of transportation for ordinary people has reached the order of nearly 50 million units. In addition to takeaway / express electric two-wheeled vehicles, recreational electric vehicles, electric tricycles, etc., the number is already very large. The performance of the controller as the main part has seriously affected the product quality of the electric vehicle as well as the production process an...
