The second connecting rod 3 is specifically hingedly connected to the mounting frame 4 through the first transverse portion 30, and the connection method between the two is the same as the connection method between the first connecting rod 2 and the mounting frame 4 mentioned above, which will not be repeated here.

[0064] Here, in order to realize the hinge between the second transverse portion 302 and the slider 6, continue to refer to Figure 5 As shown in the figure, as a preferred embodiment, the second connecting rod 3 is connected to the slider 6 through the step screw 10, and one end of the second connecting rod 3 is rotatably arranged on the light rod part of the step screw 10. In addition, a limiting sleeve 9 is provided on the step screw 10, and the limiting sleeve 9 is used to limit the displacement of the second connecting rod 3 along the axial direction of the step screw 10.

[0065] Based on the above overall description, when the seat table board assembly of this embodiment is used, the table board 1 is first unlocked, and then the table board 1 is manually flipped over, so that the table board 1 is unfolded to a horizontal unfolded state under the drive of the transmission mechanism. Then, according to the use requirements, the table board 1 is slid forward and backward to adjust the table board 1 to a suitable front and rear position, so as to have better use convenience.

[0066] At this time, to prevent the table board 1 from sliding backward excessively and detaching from the slider 6, as a further implementation manner, a limit block (not shown in the figure) is provided on the sliding housing 5 and located in the avoidance portion 502, and a mating block (not shown in the figure) that extends into the avoidance portion 502 is provided on the slider 6.

In addition, to prevent the table board 1 from sliding forward excessively, as a preferred embodiment, the second connecting rod 3 abuts against the table board 1, which can limit the sliding displacement of the table board 1 close to the mounting bracket 4.

[0067] That is to say, the inclined portion 303 of the second connecting rod 3 can abut against the table board 1 to limit its forward sliding displacement. Of course, in addition to adopting the above structure, other conventional settings can also be used to limit the sliding displacement of the table board 1. In addition, it should be further pointed out that in order to stably hold the table board 1 at the position after sliding, a rubber pad can be provided on the slider 6 and abuts against the groove wall of the sliding groove through this rubber pad. Among them, the setting of the rubber pad can increase the friction between the slider 6 and the sliding housing 5, and can play a damping role, so as to better maintain the state stability of the table board 1 and effectively prevent the table board 1 from rattling.

[0068] Therefore, for the seat table board assembly of this embodiment, by adopting the above structure, different passengers can adjust the front and rear positions of the table board 1 according to their own needs, which can improve the convenience and comfort of using this seat table board assembly.

[0069] In addition, another object of this embodiment is to propose a seat, and the seat is provided with the seat table board assembly as described above.
