[0030] As Figures 1 to 12 shown, a business vehicle seat table board includes a first table board 1, a second table board 2, a folding arm 3, a rotary arm 4, and a support arm 5;

[0031] The first table board 1 is connected to the second table board 2 through a first rotary damper 6. The bottom end of the second table board 2 is arranged on a folding arm 3, and the folding arm 3 is used to support the second table board 2 and the first table board 1. The folding arm 3 is connected to a rotating arm 4 through a third rotary damper 8, the rotating arm 4 is connected to a support arm 5 through a fourth rotary damper 9, and the support arm 5 is arranged in the seat armrest box; the support arm 5 is used to support the rotating arm 4 and the folding arm 3, and further support the second table board 2 and the first table board 1. The folding arm 3 rotates along the third rotary damper 8 to adjust the angle between the folding arm 3 and the rotating arm 4; after the rotating arm 4 rotates along the fourth rotary damper 9, the rotating arm 4 is located above the support arm 5 or on one side of the support arm 5.

[0032] When the seat table board of the business vehicle of the present utility model is in use, the first table board 1 can be rotated according to requirements to realize the angle change between the first table board 1 and the second table board 2; as a preferred embodiment, the first table board 1 in the present application forms an angle of 0-180° with the second table board 2 after rotating along the first rotary damper 6; since the first table board 1 and the second table board 2 are connected by the first rotary damper, the first table board 1 can hover at any angle of 0-180° after rotating along the first rotary damper to adapt to different usage requirements. For example, as Figure 4 and Figure 5 shown, the first table board 1 can be rotated along the first rotary damper 6 to form an angle A of about 100° with the second table board 2, which is convenient for placing items on the second table board 2, and the first table board 1 realizes the support in the height direction of the items. For example, various electronic products can be placed on the second table board 2, and the first table board 1 realizes the support for the backs of various electronic products, which is convenient for improving the comfort of passengers; as Figure 3 shown, according to requirements, the first table board 1 can also be adjusted to form an angle of 180° with the second table board 2. At this time, both the first table board 1 and the second table board 2 are horizontally arranged, which is convenient for increasing the area of the table board and is convenient for placing books or dining on the table board; and the second table board 2 rotates through a second rotary damper 7 to adjust the positions of the first table board 1 and the second table board 2 on the folding arm 3, which is convenient for adapting to the usage requirements at different positions and improving the adaptability of the table board. In order to facilitate the support for the first table board 1 and the second table board 2 and ensure the horizontal setting of the second table board 2, the folding arm 3 in the present application is horizontally arranged. In order to further support the folding arm 3 through the rotating arm 4, when the table board is in use, an angle B of about 100° is maintained between the rotating arm 4 and the folding arm 3.

[0033] On the upper surface of the first table board 1 of the present application, there is a mirror 10 to meet the makeup needs of passengers. When the mirror is needed, the first table board can be rotated along the first rotary damper, so that an angle of about 100° is formed between the first table board 1 and the second table board 2, which is convenient for passengers to use the mirror.

[0034] When the table board of the business vehicle seat in the present application is not in use, it can be stored in the seat armrest box, reducing the occupation of the vehicle interior space and improving the comfort of passengers. When the horizontally arranged first table board 1 and the second table board are stored, first, as Figure 3 , Figure 6 and Figure 7 shown, hold the first table board 1 by hand and move the first table board 1 along the first rotary damper 6 towards the second table board 2 until the first table board 1 overlaps on the second table board 2. At this time, the angle between the first table board 2 and the second table board 2 changes from the flat 180° to 0°. The shapes and sizes of the first table board 1 and the second table board 2 in the present application are the same, which is convenient for the first table board 1 to completely cover the second table board 2 and avoid the problem that the volume of the first table board 1 or the second table board 3 is too large and not convenient for overlapping storage. As a preferred embodiment, the bottom end of the second table board 2 in the present application is arranged on the folding arm 3 through the second rotary damper 7, and the bottom end of the second table board 2 rotates on the folding arm 3 along the second rotary damper 7. More preferably, the second rotary damper 7 is arranged at a position offset from the center of the bottom end of the second table board 2. Then, after the second table board 2 rotates along the second rotary damper 7, as Figure 8 and Figure 9 shown, the adjustment of the length between the end of the second table board 2 far from the folding arm and the folding arm before and after the rotation of the second table board 2 is realized, which is convenient for reducing the overall length after the table board is stored and facilitating storage. Since the bottom end of the second table board 2 is arranged on the folding arm 3 through the second rotary damper 7, the second table board 2 rotates along the second rotary damper 7 until the second table board 2 rotates 180° in a circle, realizing the adjustment of the direction of the second table board 2 driving the first table board 1. Then, lift the folding arm 3 upwards along the third rotary damper 8, as Figure 10 shown, realizing that the angle between the folding arm 3 and the rotating arm changes from about 100° to 180° with the rotating arm, and the folding arm 3 is located at the top of the rotating arm 4. Finally, rotate the rotating arm 4 towards the support arm 5 side, and drive the folding arm 3 through the rotating arm 4 and then drive the second table board 2 to rotate towards the rotating arm 4 side, as Figure 11 and Figure 12 shown, realizing the folding and storage of the table board, which is convenient for fittingly placing the folded and stored table board into the seat armrest box, reducing the occupation of the table board on the interior space of the business vehicle and improving the comfort of passengers.

[0035] As a preferred embodiment, a support plate 11 is provided between the bottom end of the second table board 2 and the folding arm 3 in the present application. The folding arm 3 and the rotating arm 4 are supported by the support plate 11, enhancing the overall structural strength of the table board and improving the support performance of the table board. More specifically, one end of the support plate 11 is arranged on the rotating arm 4 through a rotating shaft, the other end of the support plate 11 is arranged on the moving seat 12 through a rotating shaft, the moving seat 12 is arranged in a sliding groove 13 at the bottom end of the folding arm 3, and the moving seat 12 moves along the sliding groove 13. When the folding arm 3 is lifted upward along the third rotary damper 8 to change the 100° rotation between the folding arm 3 and the rotating arm to 180° between the folding arm 3 and the rotating arm, the support plate 11 moves in the sliding groove 13 through the moving seat 12. That is, during the process of storing the table board, the support plate 11 also moves along the sliding groove of the folding arm 3 with the change of the angle between the folding arm 3 and the rotating arm 4, reducing the space occupation, facilitating the reduction of the overall volume of the stored table board, and reducing the space occupation in the seat armrest box.
