Document Type and Number:
WIPO Patent Application WO/2021/143106
Kind Code:
A1
Abstract:
An electric lifting platform control system enabling a retreat function when encountering an obstruction. The control system comprises a controller, a table (1), and a lifting vertical column (2) for driving the table (1) to move vertically. A first grating component, a second grating component, and a third grating component are respectively provided, and the third grating component is divided into two portions, that is, a fourth grating component and a fifth grating component. The fourth grating component and the first grating component are matched to form a first grating group. The fifth grating component and the second grating component are matched to form a second grating group. Each of the first grating group and the second grating group is spaced apart from a lower surface of the table (1), and is electrically connected to the controller. The system improves detection reliability, and enables a retreat function when encountering an obstruction.
