Title:
SINGLE-MOTOR L-SHAPED STANDING DESK
Document Type and Number:
WIPO Patent Application WO/2023/201606
Kind Code:
A1
Abstract:
A single-motor L-shaped standing desk, which relates to the technical field of standing desks. The standing desk comprises an L-shaped cross beam support (1). A lifting mechanism (2) is mounted on the L-shaped cross beam support (1), and the lifting mechanism (2) comprises a first lifting column (3), a second lifting column (4), a third lifting column (5), a first connecting rod (6), a second connecting rod (7), and a vertical motor (8). First gears (10) are coaxially mounted at the tops of the first lifting column (3), the second lifting column (4) and the third lifting column (5). Second gears (11) are coaxially mounted at two ends of the first connecting rod (6). Third gears (12) are coaxially mounted at two ends of the second connecting rod (7). The vertical motor (8) is in transmission connection with the first connecting rod (6). The first connecting rod (6) is driven by means of the vertical motor (8) to rotate, and the second gears (11) and the first gears (10) are engaged with each other, thereby driving the first gears (10) and the third gears (12) engaged with the first gears (10) to rotate at the same time, such that the first lifting column (3), the second lifting column (4) and the third lifting column (5) rotate and ascend and descend at the same time, thus preventing lifting height differences, and use costs and power consumption may be reduced by using a single motor driver.
