Height adjustment mechanism, platform and method
First Claim
1. A height adjustment platform, comprising:
- a first working table;
a bottom bracket;
at least one lifting arm comprising;
a first elongate portion and a second elongate portion, wherein the first and second elongate portions have a same shape and are displaced parallel to each other;
a first joint device and a second joint device, wherein the first and second joint devices have a same shape and are displaced parallel to each other and are perpendicular to the first working table, wherein opposite ends of each of the first elongate portion and the second elongate portion are coupled to the first joint device and the second joint device, respectively;
wherein the first and second elongate portions and the first and second joint devices are configured to move in a same plane during motion of the table height adjustment;
at least one driving mechanism configured to drive and lock the lifting arm, wherein a first end of the driving mechanism is connected to the first elongate portion of the lifting arm and a second end of the driving mechanism is connected to the second elongate portion of the lifting arm; and
at least one control switch configured to control the driving mechanism;
wherein an angle θ
is formed between the driving mechanism and the lifting arm;
wherein the first joint device is coupled to the first working table at a fixed location along the first working table;
wherein the second joint device is coupled to the bottom bracket at a fixed location along the bottom bracket; and
wherein each of the ends of the first and second elongate portions attached to the first joint device are in vertical alignment and each of the ends of the first and second elongate portions attached to the second joint device are in vertical alignment such that an angle α
ranging from 0 to 60 degrees is formed between the lifting arm and the bottom bracket.

Abstract
A height adjustment mechanism is provided. The height adjustment mechanism includes a lifting arm, a driving mechanism configured to drive and lock the lifting arm, and a control switch configured to control the driving mechanism; the driving mechanism is coupled to the lifting arm, and an angle is formed between the driving mechanism and the lifting arm. A height adjustment platform and method is also provided. The height adjustment platform includes a first working table, a bottom bracket, a lifting arm, a driving mechanism configured to drive and lock the lifting arm, and a control switch configured to control the driving mechanism; two opposite ends of the lifting arms are separately coupled to the first working table and the bottom bracket, the driving mechanism is coupled to the lifting arm, and the angle is formed between the driving mechanism and the lifting arm.
