A self-balancing table assembly

Abstract

The present invention provides a self-balancing table assembly. The self-balancing table assembly is set in an electric seat. The electric seat is provided with: a motor that rotates under the drive of the motor and drives the seat back to realize angle adjustment. The synchronizing rod, and the table board arranged on the back of the seat back through a table board rotating shaft, the self-balancing table board assembly includes: a gear box mechanism, including: a gear box housing, assembled in the gear box housing and being driven by the synchronizing rod A transverse bevel gear that penetrates axially, a longitudinal bevel gear that meshes with the transverse bevel gear; a worm gear mechanism, including: a worm gear box housing, a worm gear that is concentrically assembled with the table rotation axis, and a worm that engages with the worm gear; and connecting the longitudinal Flexible shafts for bevel gears and worms. The present invention is based on the existing electric seat, in which a gear box mechanism, a flexible shaft and a worm gear mechanism are added to provide an automatic seat that can automatically follow the change of the inclination angle of the backrest and adjust the inclination angle of the table so that it is always parallel to the floor. Balance table assembly.

Description

technical field [0001] The invention relates to a table top, more particularly to a self-balancing table top assembly. Background technique [0002] Currently on the market, when the small table mounted on the back of the seat back is in use, the angle between the small table and the chair back remains constant without manual intervention. That is to say, the small table board can not automatically adjust the angle to keep the level with the change of the seat back angle. [0003] In actual use, if the tray table cannot be self-leveled with the change of the backrest angle of the seat, the rear occupants need to manually adjust the inclination angle of the tray table to restore the level when using it. Due to the limitation of the current tray table structure ( Such as gear structure), in some cases even can not achieve level, to a certain extent, causing inconvenience to the rear occupants. Another situation is that the items that have been placed on the small table may b...

Problems solved by technology

[0004] The purpose of the present invention is to provide a self-balancing table board assembly, so as to solve the problem that the small table board on the back of the seat back in the prior art cannot always be kept horizontal due to the change of the inclination angle of the backrest, which affects the horizontal use of the table board by the rear passengers.
