Method for preventing colliding dining table board during rotation of rail traffic passenger car seat, and electric dining table board

Abstract

The invention relates to the technical field of rail traffic passenger car seat accessories, in particular to a method for preventing colliding a dining table board during the rotation of a rail traffic passenger car seat, and the electric dining table board. On the basis of an original structure of a dining table board, a detection device, a driving device, a knob motor and an alarm are arranged,wherein the detection device is used for detecting whether the dining table board is collected to a seat back or not; the driving device is used for driving the dining table board to be collected toward the seat back. Under a situation that an existing compartment structure and car seat structure are not changed, the dining table board can be collected and locked, the problems that time and laborare wasted for manually collecting the dining table board previously are solved, commutation time in a rail traffic train camp can be greatly shortened, manpower and operation cost can be lowered, apossibility that the dining table board of the seat and a compartment body collide is avoided, and energy saving and consumption reduction are realized. Meanwhile, the electric dining table board hasthe functions of monitoring the state of the dining table board of the seat and carrying out fault alarming, thus facilitating overhaul and maintenance.

Description

technical field [0001] The invention relates to the technical field of rail transit passenger car seat accessories, in particular to a method for preventing a rail transit passenger car seat from colliding with a dining table when rotating and an electric dining table. Background technique [0002] With the rapid development of high-speed trains, more and more people travel by rail transit passenger cars such as high-speed trains and EMUs, and passengers have higher and higher requirements for the comfort and convenience of the riding environment, making high-speed trains not only for passengers The means of transportation that drive to a certain destination should also provide passengers with more comfortable functions such as rest, entertainment, work and dining. [0003] In order to meet the needs of passengers, current high-speed trains are all provided with dining table boards for passengers to have meals, place cups, notebook computers and other purposes. The existing...

[0004] But for high-speed trains such as high-speed trains, before the train arrives at the terminal and returns, the seat needs to be rotated 180° so that the passengers face the direction of the train. If the chair falls during rotation, it will cause the table board to collide with the windows of the train, other seats, etc., causing damage

However, it often happens that the table board is not put away in actual use. When passengers get off the train, some passengers do not put the table board away, or the cleaning staff forget to put the table board away when cleaning the train. If the table board is put away and fixed It is not firm and may fall when turning

Due to the short stop time of the train, the crew or cleaning personnel have to clean the car and rotate the seat, the time is tight, the workload is heavy, and the work intensity is high, which is not conducive to the rapid operation of the train and cost saving
