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.

Claims

1. A control method of an electrical adjustable table, comprising:

a) activating an internal setting value or a user setting value;

b) entering a static status;

c) receiving an operation via a hand control device of the electrical adjustable table and extending or shrinking at least a table foot in a first direction according to the operation to adjust a height of a table plate of the electrical adjustable table; and

d) stopping adjusting the height of the table plate when sensing the table plate being tilted via at least one motion sensor unit of the electrical adjustable table during adjusting the height of the table plate.

2. The control method of the electrical adjustable table of claim 1, wherein the motion sensor unit is a gyroscope or an accelerometer sensor, and the step d) is performed by sensing a first tilt angle via the motion sensor unit and determine whether the table plate is tilted according to the first tilt angle.

3. The control method of the electrical adjustable table of claim 2, wherein the step d) is performed by determining the table plate being tilted when the first tilt angle is not less than 0.3 degree.

4. The control method of the electrical adjustable table of claim 1, wherein the step d) comprises further adjusting the table plate to a second direction opposite to the first direction to adjust the height of the table plate to a safety distance when stopping adjusting the height of the table plate.

5. The control method of the electrical adjustable table of claim 4, wherein the step d) is performed by further adjusting the height of the table plate heading the first direction after adjusting the table plate heading to the second direction to the safety distance.

6. The control method of the electrical adjustable table of claim 1, wherein after the step c), the control method further comprises a step e):

entering a safety mode when sensing an obstacle via at least one obstacle sensor unit of the electrical adjustable table during adjusting the height of the table plate.

7. The control method of the electrical adjustable table of claim 6, wherein after step e), the following steps are performed:

e1) sensing a first distance between the table plate and the obstacle via the obstacle sensor unit in the safety mode; and

e2) stopping adjusting the height of the table plate and issuing a first warning if determining the first distance being not larger than a first distance setting value.

8. The control method of the electrical adjustable table of claim 7, wherein after the step e1, the following step is performed:

if determining the first distance being not less than a second distance setting value, adjusting the height of the table plate heading to the first direction, wherein the second distance setting value is larger than the first distance setting value.

9. The control method of the electrical adjustable table of claim 6, wherein after the step e), a step e4 is comprised:

adjusting the position of the table plate horizontally to avoid meeting the obstacle.

10. The control method of the electrical adjustable table of claim 1, wherein after the step b), a step f) is comprised:

when sensing the table plate being tilted via the motion sensor unit in the static status, entering a response mode and issuing a warning.

11. The control method of the electrical adjustable table of claim 10, wherein the step f) is performed by sensing a second tilt angle via the motion sensor unit and determining the table plate being tilted when the second tilt angle is not less than 1 degree.

12. The control method of the electrical adjustable table of claim 10, wherein a step f1) is performed after the step f):

extending a table foot plate of the electrical adjustable table in the response mode.

13. The control method of the electrical adjustable table of claim 10, a step f2) is comprised after the step f):

lowering the height of the table plate in the response mode.

14. The control method of the electrical adjustable table of claim 10, a step f3) is comprised after the step f):

adjusting the position of the table plate horizontally in the response mode.
