[0010] The beneficial effects of the utility model are:

[0011] The seat back electrically adjustable table frame adjusts the angle of the table frame electrically. The table frame can be adjusted at multiple angles. The angle of the table frame is adjusted according to the seat back angle, which can better meet the needs of rear passengers. The operation is quick and easy, and it is convenient for rear passengers to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 The utility model provides a technical solution: a seat back electrically adjustable table structure frame 4, comprising a mounting seat 1, a driving motor 2, a recliner 3, a connecting rod group and a table frame 4. Mounting seats 1 are respectively provided on both sides of the table frame 4, and the two mounting seats 1 are respectively fixedly connected to the seat back frame. The fixed end of the driving motor 2 is fixedly connected to one of the mounting seats 1, and the output end is fixedly connected to the recliner 3. The recliner 3 is driven by the driving motor 2, and the recliner 3 is arranged on the corresponding mounting seat 1.

[0018] The connecting rod group includes a supporting connecting rod 51 and a linkage connecting rod 52. The shapes of the supporting connecting rod 51 and the linkage connecting rod 52 are similar to a zigzag shape. One end of the linkage connecting rod 52 is connected to the mounting seat 1 for limited rotation, and the other end is connected to the table frame 4 for limited rotation. One end of one supporting connecting rod 51 is fixedly connected to the angle adjuster 3, and the other end is connected to the table frame 4 for limited rotation. One end of the other supporting connecting rod 51 is connected to the mounting seat 1 for limited rotation, and the other end is connected to the table frame 4 for limited rotation. The connection position of the supporting connecting rod 51 and the table frame 4 is set at one end of the table frame 4 close to the mounting seat 1, and the connection position of the linkage connecting rod 52 and the table frame 4 is set at the middle position of the table frame 4. There is a certain distance between the connection position of the linkage connecting rod 52 and the table frame 4 and the connection position of the supporting connecting rod 51 and the table frame 4. When the driving motor 2 works to open the table frame 4, due to the different rotation arcs of the linkage link 52 and the support link 51, interference occurs between the two, so the support link 51 stops after rotating to a certain angle, and this position is the maximum opening angle of the table frame 4.

[0019] A torsion spring is arranged at the position where the supporting link 51 is connected to another mounting seat 1. The preload force of the torsion spring is consistent with the opposite direction of the opening direction of the table frame 4. Its function is to provide buffering and damping to prevent the risk of shaking and abnormal noise during the adjustment of the table frame 4.

[0020] The opening or closing of the table frame 4 is completed by the driving motor 2 as the driving element.

[0021] In order for the table frame 4 to better adapt to the angle of the seat back, in this embodiment, preferably, the drive motor 2 is communicated with the central control system in the car, and when the seat back is adjusted in angle, the drive motor 2 will be adjusted according to the angle of the seat back.

[0022] In order to better detect the working state of the table frame 4, in this embodiment, preferably, the mounting base 1 is provided with a position sensor, and the position sensor detects whether the small table frame 4 is opened and ensures that it is in a usable state.

[0023] Finally, it should be noted that the above description is only a preferred example of the present utility model and is not intended to limit the present utility model. Although the present utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
