Abstract

The invention discloses an electric bicycle controller. The advantages of the controller are that the controller has a miniaturization design and lower demands of installation space, terminals and lead wires are improved, automatic welding can be completely realized, the controller adopts a buckle type shell design and the assembly efficiency of the controller can be enhanced. The controller includes an upper cover of a shell, a lower cover of the shell, an upper plate of a circuit board, a lower plate of the circuit board, connecting terminals between plates, a power tube, lead terminals anda heat conduction material. The upper cover of the shell is connected and embedded to the lower cover of the shell through a buckle structure; the upper plate of the circuit board and the lower plateof the circuit board are in mechanical connection and electric connection through the connecting terminals between plates; the lower plate of the circuit board adopts an aluminum substrate structure;and the heat conduction material is filled between the lower plate of the circuit board and the lower cover of the shell, and the lower plate of the circuit board being fixed on the lower cover of theshell through bolts.

Description

technical field [0001] The invention relates to an electric vehicle controller, in particular to an electric vehicle controller with miniaturization, convenient production and assembly, and excellent waterproof performance. Background technique [0002] In 2012, the Electric Bicycle Association proposed for the first time that electric bicycles should evolve to be "light, refined, smart and high". Judging from the market trend in recent years, electric bicycles are also developing in the above direction, especially in terms of "lightness and compactness", which is the focus of market competition. [0003] In the process of improving the lightness of electric bicycles, the controller supporting the vehicle can no longer meet the needs of the increasingly light electric bicycle, and the market continues to be more integrated and smaller in size and other electric bicycle controllers. [0004] At the same time, most of the production and assembly of electric bicycle controller...
