Control method for electrical adjustable table
First Claim
1. A control method of an electrical adjustable table, the electrical adjustable table comprising a table plate, at least one table foot, a lifting structure, a hand control device, at least one motion sensor unit and a control box, the control method comprising:
- a) activating an internal setting value or a user setting value at the control box for completing initialization setting;
b) entering a standby status for enabling to be operable;
c) receiving an operation via the hand control device and controlling the lifting structure to extend or shrink the at least a table foot in a first direction according to the operation to adjust a height of the table plate;
d) controlling the lifting structure to stop adjusting the height of the table plate when sensing the table plate being tilted via the at least one motion sensor unit during adjusting the height of the table plate;
e) retrieving a first length of the at least one table foot during adjusting the height of the table plate;
f) retrieving a second length of the at least one table foot after a first time period elapses;
g) when determining that an extending or shrinking speed of the at least one table foot being too fast according to the first length, the second length and the first time period, controlling the lifting structure to slow down the extending or shrinking speed; and
h) when determining the extending or shrinking speed being too slow according to the first length, the second length and the first time period, controlling the lifting structure to increase the extending or shrinking speed.

Abstract
A control method of an electrical adjustable table is provided. The control method of the electrical adjustable table includes following steps. Initialize an internal setting value or a user setting value. Enter a static status. Extend or shrink a table foot for adjusting the height of a table plate heading to a first direction according to an operation to a hand control device. Stop adjusting the height of the table plate when a motion sensor unit is used and detects the table plate tilted during adjusting the height of the table plate. The method effectively prevents the table plate to keep lifting when the table plate hits an obstacle to avoid objects fallen, the obstacle damaged or malfunction of the electrical adjustable table.
