AI Technical Summary

Technical Problem

Existing motor controllers often have excessively long wiring harnesses that cannot be wound up, resulting in exposed harnesses that are prone to bending and damage, affecting normal use. Additionally, they cannot effectively cool down under high loads, impacting their lifespan.

Method used

The design incorporates a winding wheel, shaft, and rubber clips to wind up the wire harness. Active cooling is achieved through components such as cooling pipes, heat sinks, and micro pumps. The combination of cooling pipes, heat sinks, micro pumps, heat exchange fins, and radiators forms a highly efficient heat dissipation system.

Benefits of technology

It achieves effective winding of the wire harness, protecting it from damage, while actively cooling the motor controller to improve its lifespan and reliability.

Abstract

The utility model discloses a motor controller with a heat dissipation structure, and the technical scheme is that the motor controller comprises a support and a box body, the top of the support is provided with the box body, the box body is internally provided with a motor control board through a supporting column, the middle of the rear surface of the box body is provided with a wire holder, and the middle of the interior of the wire holder is provided with a rotating shaft. A winding wheel is installed on the outer surface of the rotating shaft, a positioning screw is installed on the outer surface of the winding wheel, a rubber buckle is installed on the outer surface of the winding wheel, and a connecting wire is arranged at the position, located at the winding wheel, of the interior of the wire holder. The motor controller with the heat dissipation structure solves the problems that a connecting wire harness of an existing motor controller is prone to being too long during paying off, the too long wire harness cannot be wound in the wiring process, the too long wire harness is exposed at the connecting position and prone to being bent and damaged, and normal use of the motor controller is affected, the protection effect of the wire harness is improved, and the service life of the motor controller is prolonged. Therefore, the normal use of the motor controller is ensured.
