Description

Technical Field

[0001] The utility model relates to the technical field of electric bicycle manufacturing, in particular to a high-performance controller device for an electric bicycle. Background Art

[0002] As an environmentally friendly and convenient means of transportation, electric bicycles are widely used in daily life and work; with the continuous progress of technology and the continuous development of the market, higher requirements are put forward for the performance of electric bicycles in order to bring people a more comfortable, convenient and environmentally friendly travel experience.

[0003] In related technologies, the controller device, as the core component of an electric bicycle, is responsible for controlling the speed, start, stop and various protection functions of the motor. The performance of the controller device directly affects the quality of the electric bicycle. Since the controller device generates a certain amount of heat during operation, if the heat dissipation design is not good, it is easy to cause the controller device to overheat, thereby affecting its performance and service life.

[0004] However, the traditional controller device uses the method of setting heat sinks for heat dissipation. Since the heat sink is installed inside the controller device and does not directly contact its outer casing, it only dissipates heat through air transmission, with low heat dissipation efficiency, and will cause the components inside the controller device to work at a high temperature for a long time, affecting its performance.
