Abstract

Revised Summary Date 5/2/2016 TV lift mechanism with separate drive electric motor drive unit By developing for Solved this problem by developing a separate motor drive structure with Control circuit series Reducing the use of the slide rail, the main feature of the invention is the introduction of the principle of Screw threads to change from circular motion to straight axial Electric motor transmits power through Toothed belt to drive screw threads And two sets of drive control circuits, combined with two small side rail sets and a TV mount, are assembled in a metal structure. -------------------------------------------------- -------------------------------------------------- ----------------------- TV lift mechanism with electric motor driven separate axis. By controlling the payment Power to the drive unit with two separate drive electric motors working in unison to help drive the TV mount to move smoothly and precisely, reducing stumbling or jamming during movement. Reduce vibration This made the structure smaller due to the separation of the electric motor drive axis from the screw thread axis. By using a belt The gear tooth is the transmission. It is also possible to reduce the size of the expensive and difficult to maintain slide rail kits to reduce production costs.
