Description

Technical Field

[0001] This utility model relates to the field of controller technology, specifically to an integrated plug-in controller structure. Background Technology

[0002] The electric-assist bicycle controller is one of the core components of an e-bike. It is mainly responsible for managing and coordinating the operation of the e-bike's motor, battery, sensors, and other components to achieve switching of assist modes and optimization of riding status.

[0003] Currently, the internal wiring harnesses of electric bicycle controllers are mostly connected to the PCB board via distributed soldering. When the controller needs to perform multiple functions, the wiring harnesses are numerous, scattered, and prone to interference with other components, resulting in low internal space utilization. Furthermore, the soldering efficiency is low, and there is a risk of incorrect soldering position identification.

[0004] Patent document CN219305278U discloses an electric vehicle controller and an electric vehicle. The electric vehicle controller includes: a heat sink; six to twelve power transistors soldered to a circuit board; at least four thermal relays thermally connected to the metal backplate of the power transistors; and a terminal device electrically connected to the circuit board, with its external power input facing one direction and its three-phase motor output facing another direction.
