Problems solved by technology

[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

Embodiment 1

[0029] In the method for preventing the rail transit bus seat from colliding with the dining table when the seat is rotated in this embodiment, before the seat is rotated, a detection device is used to detect whether the dining table on the rear side of the seat is retracted, and if it is not retracted, the driving device is used to drive the dining table to the opposite direction. Stow the back of the chair, and then use the locking device to lock it on the back of the chair, then turn the seat, and continue to monitor whether the dining table leaves the back of the chair during the turning process, and stop turning the seat if the dining table leaves the back of the chair And sound the alarm. On the one hand, the method can detect whether the dining table board is put away for processing, and on the other hand, prevents the dining table board from leaving the chair back during the rotation process of the seat. In the prior art, the position detection, automatic storage, and ...

Embodiment 2

[0035] like figure 1 , figure 2 Shown, a kind of electric table board is used for the method for preventing rail transit passenger car seats from colliding with the table board when rotating, and it includes a table board 1, a first rotating shaft 2, a support arm 3, a second rotating shaft 4 and a The dining table board 1 is locked on the locking knob 5 on the back side of the chair. The dining table board 1 is rotatably connected to one end of the support arm 3 through the first rotating shaft 2. The first transfer 2 support arm 3 and the second transfer 4 are both two. The other end of the support arm 3 is rotatably connected to the back of the chair through the second rotating shaft 4, and also includes a detection device for detecting whether the dining table 1 is received on the back of the chair, and drives the dining table 1 toward the chair. The driving device, the knob motor 6 and the alarm that the back is retracted, the detection device includes a position senso...

Embodiment 3

[0043] like image 3 As shown, this embodiment provides another driving device for driving the dining table 1 to be retracted towards the back of the chair. Specifically, on the basis of Embodiment 2, the driving device further includes a synchronous belt 91, and the synchronous belt One end of 91 is drivenly connected with the first rotating shaft 2 through the first synchronous wheel 92, and the other end of the synchronous belt 91 is connected with the output end of the second rotating shaft 4 and the turning motor 8 through the second synchronous wheel 93 , the timing belt 91 is arranged in the support arm 3 , and in this embodiment, the timing belt 91 drives the table board 1 to rotate relative to the support arm 3 . As another embodiment, a motor may also be provided at the first rotating shaft 2 to drive the table board 1 to rotate.

[0044] Other technical features of this embodiment are the same as those of Embodiment 2, and will not be repeated here.

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...
