AI Technical Summary
In the existing technology, the lubrication and maintenance of gears controlled by stepper motors is inconvenient, and it is difficult to perform effective lubrication and maintenance, which affects the service life.
A stepper motor for high and low beam control was designed, comprising a lubrication component and an installation component. The lubrication component uses a liquid storage tank, an infusion pump, and a drip tube to lubricate and maintain the gears, while the installation component uses a heat sink and fixing screws to facilitate the installation and removal of the heat sink.
It enables convenient lubrication and maintenance between gears and easy installation of heat sinks, improving service life and practicality, and simplifying the maintenance process.
