Problems solved by technology

[0002] With the advancement of science and technology and the improvement of the quality of life, airplanes and high-speed rails have gradually become the main force for travel, and the frequency of people taking airplanes and high-speed rails is also increasing. Currently, the seats used on airplanes or high-speed rails can only adjust the backrest angle, that is, adjust the backrest The angle of the board is suitable for passengers to lie on their backs. At present, the structure of the table board is fixed and can only be rotated to match the rotation of the seat back. The movable performance of the seat cushion can realize different lying postures. After the seat cushion moves, the buckle limit is at The table on the back of the seat needs to move with the seat to ensure the stability of the table

Embodiment 1

[0033] Such as Figure 1 to Figure 5 Shown, a kind of table board structure that is used on the back of train or aircraft seat described in this embodiment, table board structure comprises table board support, table board, one end of table board support is installed with the seat that is used to install seat The arm is hinged, and the other end is hinged with the table. The back of the seat is provided with a rotating buckle, which can limit the free end so that the free end and the seat move synchronously. The seat and the seat mounting arm 4 slide connected, and the seat swings around a certain point in the front and back direction of the seat. Here, the bottom support of the seat or the seat mounting arm 4 is not limited in this example. It only needs to satisfy that the seat can swing. The so-called swing means around a certain point Make an arc back and forth. The table bracket and the table hinge are equipped with a retractable compensation mechanism; when the table is ...

Embodiment 2

[0041] This embodiment is a further limitation of the first embodiment above, and further defines the structure of the seat for swinging, such as Figure 6 to Figure 8 As shown, there are two seat mounting arms 4 in this embodiment, which are symmetrically arranged on the left and right sides of the seat to jointly support the seat, that is, one seat corresponds to two left and right seat mounting arms. The seat is supported by a support frame. The support frame includes a base frame 1 and a swivel frame 2 . The swivel frame 2 is rotatably connected to the base frame 1 . Seat installation arm 4 is provided with guide rail 41, and guide rail 41 is arc-shaped, and the seat is provided with the arc-shaped second slide block 61 that matches guide rail 41, and seat is connected with guide rail 41 by second slide block 61 so that all Said seat swings in the front-rear direction. Seat here is made up of cushion board 3, backboard 5, and cushion board 3 is connected with backboard 5,...

Abstract

The invention discloses a table board structure used on the back of a train or airplane seat. The table board structure comprises a table board support and a table board. One end of the table board support is hinged with a seat mounting arm for mounting a seat, the other end is hinged with the table board; a rotating buckle is arranged on the back surface of the seat; the rotating buckle can limitthe table board so that the table board and the seat can move synchronously. The seat is connected with the seat mounting arm in a sliding mode, the seat swings around a certain point in the front-back direction of the seat, a telescopic compensation mechanism is arranged on the hinged portion of the table board support and the table board, and in the state that the table board is limited by therotating buckle, the compensation mechanism is driven to work when the seat swings so that the table board can not be separated from the rotating buckle to be limited. Compensation for rotation of theseat is achieved through telescopic sliding of the table board and the table board support, the telescopic requirement during rotation of the seat is met, the table board is provided with the springplunger, the position of the first sliding block can be locked, and the stability of the table board during use is guaranteed.
