The table plate structure is provided with a telescopic compensation mechanism; in the state of the free end of the rotating buckle, the seat causes the compensation mechanism to work when swinging so that the free end does not depart from the rotating buckle limit.

Specifically, the seat is supported by the seat mounting arm 4 and can be swung. One end of the table plate structure is hinged to the seat mounting arm 4, when the table plate structure is not used, the free end is limited on the back of the seat through rotation buckle, when the table plate structure is used, the free end is separated from the rotation buckle and limited, and the function of the table plate 8 can be used. When the seat is swung, the seat mounting arm 4 is fixed and cannot be swung, and likewise the table structure is not swung. If the seat swings, the track of the seat can be changed, at this time, if the table plate structure is not used, the table plate structure is limited on the back of the seat, the table plate structure can not be separated from the rotation buckle limit only by the telescopic change of the table plate structure when the seat swings, referring to the principle shown in fig. 2, the rotation radius R1 of the seat, after the seat rotates for a certain angle, the position of the table plate 8 is also changed, if the rotation buckle limit is kept, the table plate structure needs to move downwards by the distance of L1 to adapt to the position change of the seat, and the scalability of the compensation mechanism is needed.

When the table support 7 supports the table 8 horizontally, one fulcrum is provided with the rotating shaft 9, and the other point is provided with the limiting stop pin 84 of the arc groove 701. The arc groove 701 is arranged to facilitate the rotation and retraction of the table board 8, when the stop pin 84 reaches the top of the arc groove 701, the arc groove 701 plays a limiting and supporting role for the stop pin 84. The first spring 86 is compressed, and in a normal state, the first spring 86 causes the first slider 83 to approach the table support 7, even though the table 8 and the table support 7 are extended to the longest state. When the seat is near standing position, need table 8 and table support 7 to be the longest state, the seat swing back is the posture of lying on the back, and table 8 and table support 7 are the state of shortening this moment, overcome the elasticity of first spring 86 and can shorten, therefore, when table 8 is spacing behind the seat, the seat rotates, and first spring 86 satisfies the elasticity of table structure for providing a telescopic distance.
