Kind Code:
A1
Abstract:
Provided is a dual-powered raising/lowering desktop, comprising a desktop cover panel (1), a support system arranged on the lower end of the desktop cover panel (1), and a drive system used for driving a support assembly; said support system comprises a base (21) and a support assembly arranged between the base (21) and the desktop cover panel (1); the drive system comprises a drive assembly arranged at the middle of the desktop cover panel (1), a rotary shaft (31) in a bearing position and connected to the output end of the drive assembly, a traction component sleeved on the rotary shaft (31), and a traction steel cable (33) positioned on the desktop cover panel (1) by means of a rotary plate (32); the traction component drives the support assembly by means of the traction steel cable (33); in the dual-powered raising/lowering desktop, the traction steel cable (33) is used to drive the support assembly, simplifying the internal structure of the dual-powered raising/lowering desktop, reducing its cost and eliminating the mechanical wear and tear of its geared transmission, thereby reducing the driving force required and the noise produced.
