Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panels, in particular to a driving mechanism of a photovoltaic cleaning robot. Background Art

[0002] Photovoltaic panels are a type of power generation device that generates direct current when exposed to sunlight. They are made up of thin solid photovoltaic cells made almost entirely of semiconductor materials. Since they have no moving parts, they can operate for long periods of time without causing any loss. Simple photovoltaic cells can provide energy for watches and computers, while more complex photovoltaic systems can provide lighting for houses and power the grid.

[0003] Nowadays, in the process of using photovoltaic panels to provide energy, long-term use will inevitably lead to dust accumulation on the surface of the photovoltaic panels, which will easily affect the energy collection efficiency of the photovoltaic panels.

However, in the process of using cleaning robots, most of them use walking transmission or roller transmission, which can easily cause scratches and damage to the surface of the photovoltaic panels or the overall drive is relatively unstable, which can easily affect the cleaning effect and efficiency.
